Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a heating evaporation device that evaporates a liquid evaporation agent by heating and diffuses its active ingredient into the air.

(Prior Art) Conventionally, a heating evaporation device of this type shown in FIG. 2 is known.

The heating evaporation device 101 shown in the figure is formed of a liquid-containing cardboard or the like, and has a rectangular impregnating material 102 impregnated with a liquid insecticide, and a metal transfer material that is firmly arranged on the base 103. It is composed of a heat portion 104 and a coil-shaped heat transfer heater 105 arranged below the heat transfer member 104.

In this heating evaporation device 101, the electric heater 105 is caused to generate heat by energization and the heat is transmitted to the impregnating material 102 via the heat transfer member 104, whereby the insecticide is heated and evaporated, and its effective component can be diffused into the air. It is like this.

(Problems to be solved by the invention) However, in the above-mentioned conventional heating evaporation device 101, in order to evaporate the insecticide impregnated in the impregnating material 102, the impregnating material 102 as a whole is evaporable at a temperature at which the insecticide can evaporate. However, there is a problem in that it takes time to start evaporation and a large amount of heat is required, resulting in high power consumption.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a heating evaporation device that can evaporate quickly and efficiently with low power consumption.

(Means for Solving the Problem) In order to achieve the above object, in the present invention, a storage chamber for storing a liquid vaporizing agent, a supply pipe having one end inserted into the storage chamber, and the other end of the supply pipe are provided. A spray nozzle capable of spraying the vaporized agent in a mist form, a panel-shaped electric heater arranged to face the jet nozzle outlet, a pump for pumping the vaporized agent interposed in the supply pipe, and a pump. A heating evaporation device is constituted by the driving means which is operated intermittently.

(Operation) In the heating evaporation apparatus according to the present invention, when the pump is intermittently operated by the driving means while the electric heater is energized, the evaporation agent in the storage chamber is sent to the spray nozzle through the supply pipe, and the electric heater is discharged from the ejection port. Is intermittently ejected in the form of a mist. The fine particles of the transpiration agent ejected from the spray nozzle are widely and almost evenly distributed over one surface of the electric heater which is generating heat, and at the same time as the contact, the active ingredient is diffused into the air.

(Embodiment) FIGS. 1 (a) and 1 (b) show an embodiment of the present invention.
FIG. 1A is a cross-sectional view of the heating evaporation device, and FIG. 1B is a block diagram of a pump side structure.

In the figure, reference numeral 21 denotes a case body, which is provided with a bottomed cylindrical lower case 22 and an evaporation chamber 23 having an upper opening.
2 and an upper case 24 detachably connected to the second case 2.

The inside of the lower case 22 is formed as a storage chamber 25. In the storage chamber 25, a liquid vaporizing agent F capable of evaporating at a predetermined temperature, for example, a deodorant containing various natural or synthetic deodorant components. It also contains fragrances, insecticides, etc.

Reference numeral 26 denotes a panel-shaped electric heater, which is composed of a thermistor or the like having a PTC characteristic, and evaporates the vaporizing agent F at a temperature at which it can be evaporated by supplying power from a power supply line (not shown). The electric heater 26 is arranged on one side of the evaporation chamber 23 in an inclined state, and its upper surface faces the opening of the evaporation chamber 23.

Reference numeral 27 denotes a spray nozzle, which is disposed laterally at the other end of the vaporization chamber 23, and has its ejection port 28 facing the upper surface of the electric heater 26. The spray nozzle 27 can eject the vaporizing agent F, which has been pressure-fed inward, from the ejection port 28 in a mist state.

29 is a supply pipe, the lower end of which is inserted into the storage chamber 25 and the upper end of which is connected to the spray nozzle 27.

Reference numeral 30 denotes a vaporizing agent pressure-feeding pump, which is interposed in the supply pipe 29 and is disposed in the upper case 24.

Reference numeral 31 is a driving means for the pump, which is connected to the power source 32 and the pump 30. The drive means 31 intermittently supplies drive power to the pump 30 so that the operation time and the stop time become a predetermined ratio. For example, after operating for 2 seconds, 2
The pump 30 is stopped for 0 second, and the operation of the pump 30 is controlled so that the operation and the stop can be repeated alternately.

Here, the evaporation operation of the above-described heating evaporation device will be described.

When the pump 30 is intermittently operated by the driving means 31 while the electric heater 26 is energized, the vaporizing agent F in the storage chamber 25 is sent to the spray nozzle 27 through the supply pipe 29 and directed from the jet outlet 28 to the electric heater 26. It is ejected intermittently in the form of mist.

The fine particles of the evaporative agent F ejected from the ejection nozzle 27 are widely and almost evenly dispersed on the upper surface of the electrothermal heater 26 which is generating heat, and at the same time as they come into contact with each other, the active ingredient is diffused into the air. .

As described above, according to the present embodiment, since the fine particles of the vaporizing agent F ejected in the form of mist are intermittently sprayed on the electric heater 26, the electric heater 26 can be quickly heated without any extra heat load. The fine particles of the evaporation agent F can be evaporated almost at the same time as the contact, and the time until the start of evaporation can be greatly shortened.

Further, since the fine particles of the vaporizing agent F can be sprayed over the upper surface of the electric heater 26 in a wide range and almost evenly by ejecting the vaporizing agent F in a mist state, the heat of the electric heater 26 is applied to the vaporized agent F thus sprayed. It can be effectively transmitted to efficiently perform the above-mentioned transpiration.

Furthermore, since the electric heater 26 can be quickly raised in temperature, it is possible to perform the above-mentioned transpiration just by heating the electric heater 26 immediately before the start of spraying, and the amount of heat required for transpiration, that is, the amount of power consumption is small. Complete.

Furthermore, the transpiration amount can be controlled arbitrarily and easily by changing the ratio of the operation time and the stop time of the pump 30.

A blower may be used as a means for assisting evaporation in the embodiment.

(Effect of the Invention) As described in detail above, according to the present invention, since the fine particles of the vaporizing agent sprayed in the form of mist are intermittently sprayed on the electric heater, there is no extra heat load on the electric heater. In addition to being quick, the fine particles of the transpiration agent can be evaporated almost simultaneously with the contact, and the time until the start of transpiration can be greatly shortened.

Further, by spraying the vaporizing agent in a mist state, the fine particles of the vaporizing agent can be spread over the electric heater in a wide range and almost evenly. Therefore, the heat of the electric heater is effectively transmitted to the sprayed vaporizing agent. Evaporation can be performed efficiently.

Further, since the electric heater can be heated quickly, the above evaporation can be performed only by heating the electric heater immediately before the start of spraying, and the amount of heat required for evaporation, that is, the power consumption can be reduced. .

Furthermore, the transpiration amount can be arbitrarily and easily controlled by changing the ratio of the operation time and the stop time of the pump.
