Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handy cleaner for sucking dust accumulated on a desk of a general household, a seat of a car, and the like, and dust entering a gap of an OA device or the like.

[0002]

2. Description of the Related Art Conventionally, because it is lightweight, compact and easy to carry, it is used for sucking dust accumulated on a desk of a general household or a seat of a car or dust entering a gap of an OA device. A handy cleaner that is preferably used is
The suction force has been relatively small, which has forced the suction port to be small. In this type of handy cleaner, a brush (brush) that covers the periphery of the suction port is preferably used to cover the small suction force. Etc. were sucked through the suction port.

[0003]

However, in the above-mentioned conventional handy cleaner with a brush, the brush is provided around the suction port, and since the suction port itself is small, the area for providing the brush is also small. Garbage was not sufficiently lifted, making it difficult to improve the cleaning speed. In order to solve this, it is only necessary to make it easier to scrape up dust, and for that purpose, the area provided with the brush may be increased or the brush may be lengthened. However, simply providing a larger area than the suction port to make it easier to remove dust makes it difficult to suck dust, especially with a handy cleaner having a small suction force. Further, if the brush is merely lengthened, there is a distance between the brush and the cleaning place (floor), and the airtightness cannot be obtained. Therefore, it is difficult to suck dust, especially with a handy cleaner having a small suction force.

An object of the present invention is to solve such a conventional problem and to provide a handy cleaner having an improved suction force.

[0005]

In order to achieve the above object, a handy cleaner according to the present invention comprises a fan for generating a suction force, a motor for driving the fan, a power supply for supplying power to the motor, A dust collection case for storing collected dust and the like, a suction port for sucking dust and the like by the suction force generated by the fan and collecting the dust in the dust collection case, and a suction path provided between the dust collection case and the suction port. A check valve for preventing leakage of collected dust and the like, a suction wall formed to surround the suction port, and a brush formed to surround the suction wall, The area ratio of the suction port is 0.2 to 0.6 times the area of the part surrounded by the suction wall.

As a result, a wide range of dust and the like can be scraped up, and a suction wall is provided, so that the clearance between the cleaning place (floor) and the suction port can be reduced to improve the airtightness. Dust and the like can be efficiently sucked.

[0007] When cleaning the uneven surface with a handy cleaner with a brush, the suction wall may hit a cleaning place such as a keyboard, for example, so that the suction wall is formed of a soft material. Is desirable.

It is desirable that the brush is formed as a brush unit and is removable. This allows
Depending on the presence or absence of irregularities in the place of use such as the seat of the car or the keyboard of the personal computer, it is possible to selectively use the brush unit with a short hair tip and a long brush tip. Further, even when the brush is damaged or becomes dirty, if the brush unit alone is replaced, the main device can be used as it is.

It is desirable that an antistatic agent is contained in each of the materials forming the dust collecting case and the mounting portion for attaching the brush. This makes it possible to reliably suck the dust and the like swept up by the brush and soared from the suction port without adhering to those portions.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is an external view of a handy cleaner of the present invention. In the figure, reference numeral 1 denotes a motor, a fan,
A case 2 having a secondary battery or the like, a dust collecting case 2 having a suction port at the tip and a filter inside, a mounting portion 7 for mounting the brush unit 4, and a mounting unit 4 for mounting the brush unit 4. When it is attached to 7, it is attached at the position shown by the frame line 3. In the figure,
No suction wall is provided for ease of explanation. Since the main body case 1 and the dust collection case 2 are detachably connected,
By removing this, dust in the dust collecting case 2 can be removed.

FIG. 2 is a perspective view of the handy cleaner of the present invention. In the same figure, the parts shown with the same figure numbers as FIG. 1 are substantially the same as the parts described in FIG.
Description is omitted. A suction wall 6 is provided inside the mounting portion 7, and the suction wall 6 reduces a gap between a cleaning place (floor) and the suction port 5 to improve airtightness, and guides dust and the like to the suction port 5. By doing so, dust can be collected efficiently.

Reference numeral 5 denotes a suction port formed by a mouth smaller than the area of the opening of the brush 3, and collects dust and the like into the dust collecting case 2 through the suction port 5 by a suction force generated by the fan 11. Reference numeral 9 denotes a check valve, which is opened when used to collect dust and the like in the dust collecting case 2 by the suction force generated by the fan 11 and is kept closed by elasticity when not in use. This prevents the collected dust and the like from flowing back out of the cleaner by backflow. Reference numeral 10 denotes a motor, which receives power supply from a power supply unit 14 formed of a secondary battery or the like and rotates the fan 11. A filter 12 prevents dust and the like collected in the dust collecting case 2 from entering the main case 1. Reference numeral 13 denotes a switch, which is turned on by the user during use, so that power can be supplied from the power supply unit 14 to the motor 10 to perform cleaning.

In this embodiment, a secondary battery is used as the power supply unit. However, it goes without saying that the same effect can be obtained by using an AC power supply or a primary battery.

As shown in FIG. 2, the handy cleaner of the present invention includes a brush 3 provided to be larger than the area of the suction port 5 and a suction wall 6 inside the brush 3, as shown in FIG. The clearance between the cleaning place (floor) and the suction port 5 is reduced to improve the airtightness, and the suction wall 6 guides the dust to the suction port 5 so that the dust can be sucked.

According to experiments by the inventors, as shown in Table 1, when the ratio of the area of the suction port 5 to the inner area of the suction wall 6 is about 0.2 to 0.6 times, It has been confirmed that the dust rate increases. When the ratio of the area of the suction port 5 to the area of the suction wall 6 is 0.25 to 0.5 times, the dust collection rate exceeds 75%, and it can be seen that this is even better. In this experiment, the ratio was changed and measured by changing the size of the suction port 5 each time, and other conditions including the suction wall 6 were unchanged.

[0017]

[Table 1]

Further, as shown in FIG. 2, the suction wall 6 is slightly shorter than the length of the brush 3 so as not to hinder the dust from being scraped up. At this time, if the length of the suction wall 6 is too short, the airtightness is impaired, and the dust collection rate is reduced. Therefore, it is desirable to make the length as long as possible without hindering the scraping-up by experiments. Further, depending on the place to be cleaned, the suction wall 6 may hit and be damaged or damaged. Therefore, it is desirable to use a soft material such as rubber or elastomer for the material of the suction wall 6.

Further, it is desirable that the brush unit 4 (the brush 3 and its attaching portion) can be removed. This makes it possible to use the brush unit as a short brush unit or a long brush unit in accordance with the presence or absence of irregularities in a used portion of a car seat, a personal computer keyboard, or the like. Further, even when the brush is damaged or becomes dirty, if the brush unit alone is replaced, the main device can be used as it is. In addition, the aforementioned suction wall 6
By removing the brush unit 4, it becomes a new tip of the suction port 5, and two types of tips, a brush and a soft material suction wall 6, can be used depending on the cleaning place. In the case of the front end portion formed by the suction wall 6 made of a soft material, the gap between the suction portion 6 and the cleaning place (floor) can be reduced to zero.

FIGS. 3 and 4 show the removal structure of the brush unit 4.
It is shown using. Claw 8 provided with brush unit 4 on mounting portion 7
And the suction wall 6 is made of a soft material, so that the brush unit 4 can be easily removed.

In the dust collecting case 2 and the mounting portion 7 of the brush unit 4, static electricity is generated by brushing of the brush 3,
To solve the problem that dust and the like easily adhere, the antistatic agent is added to the above two parts and other parts that are considered necessary.
It is desirable to prevent adhesion of dust and the like.

[0022]

As apparent from the above embodiment,
According to the present invention, a wide range of dust and the like can be scraped up, and the suction wall is provided, so that the clearance between the cleaning place (floor) and the suction port can be reduced to improve the airtightness.
Dust and the like can be sucked with the highest dust collection efficiency, and the speed of cleaning can be increased.

Further, when the suction wall is formed using a soft material, it is possible to eliminate the possibility that the suction wall may be damaged or damaged even in a cleaning place such as a keyboard.

If the brush is formed as a brush unit and can be removed, the brush unit can be divided into a brush unit having a short hair tip and a brush unit having a long brush tip depending on the presence or absence of irregularities in a use place such as a car seat or a keyboard of a personal computer. Can be used properly. Further, even when the brush is damaged or becomes dirty, if the brush unit alone is replaced, the main device can be used as it is. Instead of using a brush unit, a cleaner can be used with a suction wall made of a soft material as a tip.

By including an antistatic agent in each of the materials forming the parts such as the dust collecting case and the mounting part for attaching the brush, dust and the like that are scooped up by the brush and flutter adhere to those parts. Therefore, suction can be surely performed from the suction port.
