Description

DEVICE TO KILL HARMFUL INSECTS SUCH AS MOSQUITOES, FLIES AND

SANDFLIES

This invention refers to, in general, a device to kill insects such as mosquitoes, sandflies and other harmful insects, in particular flying insects which suck blood or body liquids. Even when in the following only mosquitoes are mentioned, the invention is nevertheless about any harmful insect, such as for instance cockroaches and in general other harmful insects, flying or not. For the sake of simplicity in all the document by "killing" it is meant not only instantaneous or fast killing but also severely injuring causing later death.

More specifically, the invention enables to protect humans and certain animals from harmful insects and optionally also to exploit the high attractive power of humans and many other animals on those harmful insects, to attract them and kill them or stun them. In the configuration of the invention which is preferred, humans or animals attract the harmful insects, but as an alternative also other artificial or natural lure can be applied to attract those harmful insects. One of the two objectives (protection or killing) may be the main one, depending on the single case.

It is well known that mosquitoes or other harmful insects, stinging, not only are very annoying, but also can transmit serious disease (also potentially deadly or disabling) , like dengue fever, yellow fever, filariasis, malaria, etc.

It is also well known that mosquitoes or other harmful insects are attracted by men and other animals, from which they take blood meals, following different stimuli, which can be released smell/gas (like carbon dioxide), view stimuli (in the human-visible spectrum or IR or UV) , heat, etc.

Other lures for mosquitoes or for other harmful insects based on one or more visible stimuli (lamps emitting radiation at different wavelengths as human-visible or ultraviolet or infrared) or smell (carbon dioxide or other substances) or other artificial or non alive lures unlikely are effective like the "natural" or living attraction given by humans or other animals or their smell or leavings (like hair or dandruff or skin particles) or substances (like sebum) from their bodies.

The effectiveness of those non alive or artificial lures can be considered relatively low if positioned near to people or animals because, when both are present, mosquitoes or other harmful insects are often attracted by people or animals more than by those non alive or artificial lures.

Several traps have been designed in the past to kill mosquitoes or pest insects. If used for mosquito prevention and control most of them are not very effective and widespread. The larvae traps, focusing on giving a place for mosquito breeding and then killing either the larvae or the newly grown (after pupae) adult mosquito, have the main disadvantage that can afflict only a very little percentage of mosquitoes, because most mosquitoes will breed in the natural environment. More effective are the traps that use attractions for the insects, if the attractants are effective. Light (or electromagnetic waves in general) only attractants seem often to be not effective for mosquitoes. More effective are gas attractants (C02, lactic acid, etc.). But all these attractants are artificial: sooner or later they expire and need recharge and they are not as much effective as natural attractants like human beings or mammals or their leavings. This invention focuses mainly on human beings and mammals and other animals or their leavings as the preferred attractants, much more effective, much more available. Some common mosquito killing is achieved by electrocution through an electrified grid, which is quite effective indeed. But an electrified grid is proven to reduce the attraction of human beings or animals on the other side of the trap, because it limits both visual and gas attraction. Also electrocuting grids need sufficient protection by weather agents and water in general. Another common used mean to kill mosquitoes is suction by a fan and a net to keep them until they dry to death. This system can be quite energy consuming, can have maintenance issues, noise issues, and its effectiveness can be matter of much discussion. There are very effective fascinating and famous mosquito killing systems using optical laser tracking system and laser burning beams. But these systems are very expensive so far and are not feasible on a wide scale above all in poor countries .

There are several previous documents with similarities and intersection with the present invention like for instance US1471585A Bessette Francis P. 1923-10-23 (will be referred to as Dl), US1399193A Grover Coe Clyde 1921-12-06 (will be ref. as D2), US6874273B1 Weisenburg 2005-04-05, WO2015097722 Stella Alessio 2015-07-02. Very distinctive in the present invention is a partly/totally disposable or removable and cleanable structure as described further on in this document and in claim 6. Very distinctive is the enclosing/entrapping structure as described further on and in claims 1, 2, 3, 7, 8, 15 (and fig. 3, 4, 5 and 6 just as possible realizations) where the insects are easily trapped and unlikely manage to escape. Very distinctive is the smart movement structure described further on in this document and in claim 15 (and fig. 1 and 5 just as possible realizations) that exploits air flow to prevent insects from escaping during the structure movement. Distinctive is coupling mechanical movements with automatic efficient triggering systems like described further on and in claims 10, 11. Distinctive is the mobile station application like described further on and in claim 13. Distinctive is the use of dirt or leavings as lure like described further on and in claims 1 and 14.

A relevant difference with found previous works (ref. for instance Dl and D2) is also the functional decomposition in a first entrapping mechanism (examples fig.3, 4, 5, 6: 1A->1B, 30A, 6A, 6B, 40, 41) and a second killing mechanism (examples fig.3, 4, 5, 6: 1B->1C, 6A, 6B) , as expressed in claims 1 and 3 and in the description further on and as will be exemplified later when explaining the example figures. This decomposition makes the device more efficient as it is more difficult for harmful insects to manage to escape. While instead in Dl it is easy (the same author explicitely admits it) and in D2 it is relatively not difficult for insects to escape.

Another relevant difference with found previous works is the decomposition of the entrapping system in several subelements, as expressed with claims 7 or 8 or example fig. 3, 4, 5, 6

(1A->1B, 30A, 6A, 6B, 40, 41) . This, compared to found previous works, makes the mechanism more efficient because, if n are the subelements, for the same active area the action on harmful insects is at least a function of n times faster

(actually more because only the entrapping function is performed, leaving the killing to a further stage of action) both if the entrapping is implemented with rotation (examples as fig. 3, 4, 5), or with translation (example as fig. 6). The exact function of n reduction factor of time depends if we fix the speed or the power or the initial and final stop stress, but in any case in rotation we have a reduction of the total moment of inertia, in translation we have a reduction by n of the amplitude of the movement. The comparison is easily made for example with Dl for a translation and with D2 for a rotation .

Another relevant difference with found previous works (for example Dl and D2) is the fact that air flow is positive for the entrapping purpouse as expressed in claim 15 and exemplified in fig. 1 and 5, or in most embodiments can be set to be at least neutral to the entrapping purpouse as in example fig. 3, 4, 6, compliant with claims 1, 7, 8. As a matter of fact in Dl and D2 the air flow will tend to blow away the insects facilitating their escape, while here claim 15 will produce an air flow tending to entrap the insects, or even without claim 15 in the example fig. 3, 4, 6, compliant with claims 1, 7, 8, it is clear how the insects already inside the device are not blown away, for how the air fluid is interacted with by the mechanism.

Aim of this invention is to realise a device to kill harmful insects, like mosquitoes, more effective and convenient than other traditional devices. This and other aims, according to this invention, are fulfilled by a device to kill harmful insects according to claim 1 attached in the following; other more detailed optional features are described in the following dependent claims.

Advantageously, the killing device according to the invention conceives that humans or animals (one or more) or their smell or leavings (like hair or dandruff) or substances from their bodies play the role of the preferred applied lure, lure that comes out to be much more effective than any lamp or gas or else .

One basic idea, preferred but not necessarily always applied in all embodiments of this invention, is to use systems with wide opening, preferably but not necessarily dark or transparent, that leave a high exchange rate of gas to better attract target insects (like mosquitoes or other bugs) and leave also higher visual attraction. The invention here described has proved to be very effective for mosquito extermination and relatively low cost. The device to kill harmful insects, like for instance mosquitoes, comprises one or more structures (6A, 6B, 6C) each having at least one opening (30A, 30B, 30C) , said structures (6A, 6B, 6C) being applied, at least partially, to at least one wall (9) of at least one space (8A) where it is usually present at least one human being or animal (8) and/or their leavings (like for instance hair or skin particles or sebum) and/or at least one artificial or natural lure for said harmful insects, while at least at the remaining surfaces of said space (8A) surfaces and/or parts and/or elements are present that do not allow passing through of said harmful insects, such as for instance made of glass, plastic, wood, masonry and/or mosquito-nets, characterized in that of the said structures (6A, 6B, 6C) at least one is provided of at least one opening wide enough, or that can be set wide enough, to let said harmful insects pass through and of the said structures (6A, 6B, 6C) at least one is provided of one or more startable motions capable of killing or severely injuring said harmful insects, for instance by consequent pressure and/or crush and/or transfixing and/or electrocution. In the following the words "killing system" will be used to refer to said one or more structures (6A, 6B, 6C) .

The startable motions can be activated and provided for example with quite simple mechanics connected to pneumatic pistons or electric engines or fuel engines or other mechanical power sources. In such a conception of course standard safety measures must be accomplished.

Said one or more structures (6A, 6B, 6C) can optionally (in most embodiments) include a structure (6B) which is provided of a sufficiently dense net or grid and/or a sufficiently small said at least one opening (30B) so that it is possible for smell/gas and light to pass through, but it is not

possible for said harmful insects to pass through.

Said one or more structures (6A, 6B, 6C) may optionally (in most embodiments) include at least one structure (6A) which has at least one startable moving part (1A->1B) that can reduce its said at least one opening (30A) small enough to allow air to pass through but not said harmful insects to pass through .

Said one or more structures (6A, 6B, 6C) may optionally (in some embodiments) include at least one structure which

includes or is at least one structure electrified with at least one voltage, capable of killing or severely injuring said harmful insects by electrocution.

Said structures (6A, 6B, 6C) may optionally (in most

embodiments) include at least one structure (6A) having at least one startable motion (1B->1C), like for instance

translation, that reduces the space between said structure (6A) and at least another one of the said structures (6A, 6B, 6C) , so to kill or severely injure said harmful insects in between, for instance by pressure and/or crush and/or

transfixing (in this case it is preferred either the surfaces are sufficiently juxtaposable or they have some transfixing structure/pins) and/or electrocution.

Optionally (in some embodiments) at least one or at least a part of one of said one or more structures (6A, 6B, 6C) may be disposable and/or optionally can be removed to be washed or cleaned .

Optionally (in some embodiments) at least one of said

structures (6A, 6B, 6C) may be provided of structures (40, 41) capable of appropriate rotation (1A->1B), preferably

transparent or dark, like for instance parallel laths or laminas and/or like for instance structures similar to window blinds, capable of rotating to a common angle (1A->1B) which leaves little room between each other so that they reduce at least one of said openings (30A, 30B, 30C) enough that air can pass but said harmful insects cannot pass through. Optionally (in some embodiments) at least part of said

rotating structures (41) may have each rotation center or each rotation axis set towards the outside of the device so that when the said rotation to a common angle is started the air tends to flow inside the device and/or there is air pressure towards the inside of the device, so that the harmful insects are more easily trapped and/or find it more difficult to escape during the rotation.

Optionally (in some embodiments) at least one of said

structures (6A, 6B, 6C) may be provided of two parts capable of sliding one on the other (1A->1B), like for instance by rotation or linear translation, to reduce at least one of said openings (30A, 30B, 30C) enough that air can pass but said harmful insects cannot pass through.

Optionally (in most embodiments) at least one of said

structures (6A, 6B, 6C) and/or at least one of the surrounding structures may be, at least in part, transparent and/or semitransparent and/or dark and/or red to enhance visual attraction of said harmful insects.

Optionally (in some embodiments) said startable motions may be started automatically on the basis of a detection system, like for instance an optical sensor and/or a machine vision system and/or laser-optics triangulation and/or ultrasonic

sensor/sensors and/or acoustic sensor/sensors and/or an audio automatic recognition system and/or pressure sensor/sensors, said detection system capable of detecting said harmful insects, said detection being optionally usable also to start the optional said openings (30A, 30B, 30C) reduction if present .

Optionally (in some embodiments) said startable motions may be started periodically and/or following certain time intervals or time functions and/or time rules, optionally subordinated to some automatic programmable calendar (date, time of the day) .

A periodic start and periodic reset of the motions, according to an appropriately low duty cycle, with short distance of time between start and successive reset and longer distance in time between reset and successive start, can allow the use of the device without human or automatic control, of course decreasing the efficiency as the system is blind, trying to kill harmful insects without detecting (by human or machine eye) when the harmful insects are present. But we can suppose, at least in the case of mosquitoes, the decrease in killing efficiency is tolerable because it was observed that

mosquitoes tend to insist for a relatively long time moving against what lets them smell and/or see the target (human, animal, leavings) but doesn't let them pass, for instance a grid (6B) . So the said low duty cycle should guarantee a non very big killing efficiency loss.

Optionally (in most embodiments) the geometric structure and/or the said one or more startable motions and/or the power of the motions may be designed not to constitute a threat of injure to humans or pets or predetermined animals, for

instance setting protection grids on one or both sides of said structures (6A, 6B, 6C) .

One possible application (in some embodiments) is in a mobile station, like a wheeled vehicle or a boat or an aircraft, preferably of dark colour, said mobile station being driven by a human being or remotely driven or automatically driven or robot driven or being a robot or drone. Said mobile station may optionally have low cleanliness, to keep the smell and/or body leavings, like skin particles or hair or sebum, of human beings and/or animals, to better attract harmful insects.

Said killing system can be applied to windows, doors or openings and gaps in general of buildings/houses or of animal stables, or it can be applied to animal cages, or to mobile stations (like cars, boats) or it can be applied as part of mosquito nets for beds (in this case using special supplementary safety measures) . Said killing system can be provided of an internal net, with dense meshes, that doesn't allow insects to pass through also when the power is off.

An application of said killing system can be either a cage provided with at least one of said killing systems, or a casing-cover to be added on an ordinary animal cage.

In any case, in any of the applications the said killing system may be a portion of the complete casing or a portion of one wall of interest, but it is appropriate that the remaining surfaces do not allow the insects to pass through (by glass, plastic, wood, mosquito net, etc.); similarly, when the killing system is applied to windows or vents in general, it is appropriate that the part which is not occupied by the system has a layer of material that doesn't allow the harmful insects to pass through (plastic, glass, etc.) and that the other windows, door-windows or vents (if not provided with the killing system) are provided with mosquito nets or kept closed (for a better effectiveness of the killing system) .

Further features and advantages of a device to kill harmful insects, like mosquitoes, according to this invention, will be more evident from the previous and following descriptions of some preferred, but not limited to, realizations and from the attached drawings .

Figure 1 shows a first realization form of the device to kill harmful insects, like mosquitoes, according to this invention, applied in an animal cage. Figure 2 shows a second realization form of the device to kill harmful insects, like mosquitoes, according to this invention, applied in a house.

Figure 3 shows details of a realization form of the device to kill harmful insects, according to this invention, where three structures 6A, 6B, 6C are shown. Structures 6A and 6C are symmetric. Structure 6B is a grid which is an example for what specified in claim 2. In figure 3, startable movements are shown in three main steps/states (1A, IB, 1C) , as an example in particular for claims 3, 5 and 7. In this example figure 3, the movement from state 1A to state IB entraps the insects which are between structures 6A and 6B . The movement between state IB and 1C kills the same entrapped insects.

Figure 4 shows details of a realization form of the device to kill harmful insects, according to this invention, where two structures 6A, 6B are shown. Structure 6B is a grid which is an example for what specified in claim 2. Differently from the realization form of figure 3, where it is not strictly necessary, here structure 6B should be sufficiently resistant and rigid to kill harmful insects in the last movement of structure 6A against structure 6B . In figure 4, startable movements are shown in three main steps/states (1A, IB, 1C) , as an example in particular for claims 3, 5 and 7. In this example figure 4, the movement from state 1A to state IB entraps the insects which are between structures 6A and 6B . The movement between state IB and 1C kills the same entrapped insects .

Figure 5 shows details of a realization form of the device to kill harmful insects, according to this invention, where two structures 6A, 6B are shown. Structure 6B is a grid which is an example for what specified in claim 2. Differently from the realization form of figure 3, where it is not strictly necessary, here structure 6B should be sufficiently resistant and rigid to kill harmful insects in the last movement of structure 6A against structure 6B . In figure 5, startable movements are shown in three main steps/states (1A, IB, 1C) , as an example in particular for claims 3, 5 and 15. The main difference with figure 4 is that each rotation axis of the laths is more external, according to claim 15, so that when the said rotation to a common angle is started the air tends to flow inside the device and/or there is air pressure towards the inside of the device, so that the harmful insects are more easily trapped and/or find it more difficult to escape during the rotation.

Figure 6 shows details of a realization form which is an example for claim 8. Two parts (4, 5) of structure 6A, capable of sliding one on the other, are shown unmounted separately and they are shown together in two possible positions (1A, IB) . According to claim 8 they can slide one on the other, in this case by linear translation. A similar situation can be realized with two parts with radial openings, sliding one on the other by rotating around a common rotation axis. In both cases it can be provided an inner second structure 6B

(realization form of claim 2) with a grid shaped in order to be able to reach pressure (after the movement according to claim 5 is completed, for instance by approaching translation) on at least most of the inner surface of the couple of parts

(4, 5) composing structure 6A.

Referring to the mentioned figures, the device to kill harmful insects, like mosquitoes and similar, object of this invention, makes use in particular of one or more of said killing systems, to be applied or inserted in one or more surfaces of several possible objects and/or systems.

At least if the main target are mosquitoes, a dark material applied completely or partially to one or more of said killing systems may improve a lot the effectiveness of the device. Or also, at least if the main target are mosquitoes, a dark material composing completely or partially at least one or more of said killing systems, may improve a lot the effectiveness of the device. The dark colour increases the probability that mosquitoes alight on the device or try to pass through the device. In practice, according to some preferred, but not limited to, realizations of the invention, those said killing systems are applied on one or more walls of a cage or animal container (rodents, birds, guinea pigs, mice, cats, dogs, etc.).

Said killing systems, also of different types, can be applied also to arrays of animal cages put in public places or next to public places to kill harmful insects of the surrounding area, they can be applied also on walls and/or on windows and/or on doors of buildings for human beings or for animals, like cows, horses, pigs, etc., with the condition of being sufficiently protected by appropriate safety measures.

Moreover said killing systems can also be set inside vents and/or as panel/porthole/portion of a window and separately openable towards the inside, with the outside always open or the outside itself openable and closable.

Applications to windows or vents must strictly take into account safety matters related to systems using methane or flammable substances according to relative rules and legislations .

In general, in all applications, optionally at least one of said killing systems can be provided with at least one protection grid, set towards the inside or the outside of the space 8A, to avoid harm to human beings, or to animals which are different (of bigger size) from the harmful target insects, or contact with plants, if present inside or outside the space 8A.

At the surface or next to the surface where the said killing system is set, optional other tools may be set, like trays to collect dead insects, fans to help the catch of said insects, nets and/or sticky substances to trap insects, UV and/or IR and/or visible wavelengths lighting systems, attractive gas or odor emitting systems and/or heat emitting systems, with the aim of improving the attraction of the harmful insects. A grid of sufficiently dense mesh may be added to said killing system so that target harmful insects are not let pass through anyway. That is particularly useful in the case when the power supply is off, for instance if the device is intentionally switched off or if batteries are discharged or in case of a blackout or in case an automatic breaker of the electric circuit switched off, with the aim of protecting nevertheless the space 8A. That is particularly useful also in the case of malfunctioning of a possible optional automatic switching on/off and/or starting system based on the automatic detection of the presence of target harmful insects.

Moreover in general the device may be optionally connected to an automatic system switching it on/off, with a calendar that is programmable specifying dates and times of the day.

Moreover, methods can be optionally applied to activate the killing system only in presence of the insect, with saving of energy (and battery life if batteries are used) . Those methods can be for instance at least one of the following: a measure of parallel conductance, an optical barrier, an artificial vision system, an ultrasonic sensor, a radar or something else, or a human being that controls the device checking when the harmful insect is present and deciding when to activate the system.

One or more of said killing systems can be integrated with one or more bed-mosquito-nets. In particular, one or more killing systems can be set on at least one side or at least on one lateral portion of a bed, while mosquito nets are installed on the other sides of the bed and on the remaining parts of the sides where one or more killing systems are set. The presence of a human on the bed, or even in his/her absence the presence of his/her smell or leavings or substances (like skin particles or hair or sebum) , will attract mosquitoes or other harmful insects to death. According to other embodiments of the invention, it is possible to use a cage of little or big size (like an aviary or a big animal cage) , which can hold animals in the internal space 8A and which is provided internally of a set of plants carefully chosen and/or basins or tubs with water that is still and/or moved, aimed at making the internal space 8A of the cage an attracting situation for the insects. Similarly to what previously described, on one or more walls or portions of walls of the cage, one or more of said killing systems are set, while on the remaining surfaces or walls of the cage mosquito nets or panels of glass, plastic, wood or other materials are set, which do not allow insects to pass through. At last, the device can be applied to a mobile station, mobile on the ground or by water or flying, for instance on wheels or on boat or on aircraft, said mobile station being preferably but not necessarily of dark colour, because, if mosquitoes are the target, the dark colour increases the attractive power and in general the probability that mosquitoes approach. In the specific case of mosquitoes, the mobile station is particularly useful to act on wide areas, considering that mosquitoes are animals quite area settled, that move relatively little.

Said mobile station can be also one remotely driven or

automatically driven or robot driven or it may be a robot. Inside said mobile station, the attraction for insects can be one or more human beings and/or one or more animals and/or other lure.

For example it was observed that in general a car, with one or more of said devices, is an effective mosquito killing mobile station and it can be supposed that its effectiveness can be helped by dark colours and by a low cleaning of the interiors (also in absence of people inside the car) . It was observed that in some occasions (but not to be taken necessarily as a general rule) mosquitoes were more attracted by a dirty car than by a human being nearby and outside of the car.

Probably a mobile station as previously described more in general, especially if it is dark and/or dirty as previously said, can be mistaken as an animal by mosquitoes, so becomes very attractive.

More in general it can be useful if said mobile station has low cleanliness inside, to keep the smell and/or body

leavings, like skin particles or hair or sebum, of human beings or animals: with one or more humans and/or animals being or having been inside the mobile station, but not necessarily inside at the same moments when the station is applied as insect killer.

From the description given, the technical features and the advantages of the device to kill insects, according to the present invention, are clear.

It is clear that several other variants can be made of the said killing device, without diverging from the principles of novelty inherent of the inventive idea, as it is clear that, in the practical realization of the invention, the materials, the forms and the sizes of the explained details may be whatsoever depending on the needs and they can be substituted with other ones technically equivalent.

11. Device as claimed in at least one of the previous claims, characterized in that said startable motions are started periodically and/or following certain time intervals or time functions and/or time rules, optionally subordinated to some automatic programmable calendar (date, time of the day) .

12. Device as claimed in at least one of the previous claims, characterized in that the geometric structure and/or the said one or more startable motions and/or the power of the motions are designed not to constitute a threat of injure to humans or pets or predetermined animals, for instance setting protection grids on one or both sides of said structures (6A, 6B, 6C) .

13. Device as claimed in at least one of the previous claims, characterized in that at least one device is applied to a mobile station, like a wheeled vehicle or a boat or an

aircraft, preferably of dark colour, said mobile station being driven by a human being or remotely driven or automatically driven or robot driven or being a robot or drone.

14. Device as claimed in claim 13, characterized in that said mobile station has low cleanliness, to keep the smell and/or body leavings, like skin particles or hair or sebum, of human beings and/or animals.

15. Device as claimed in claim 7, characterized in that at least part of said structures (41) capable of appropriate rotation have each rotation center or each rotation axis set towards the outside of the device and/or at least part of said structures (41) capable of appropriate rotation are not symmetric each with respect to its own rotation center or rotation axis so that when the said rotation to a common angle is started the air tends to flow inside the device and/or there is air pressure towards the inside of the device, so that the harmful insects are more easily trapped and/or find it more difficult to escape during the rotation.
