The ultrasonic oscillation mechanism 7 supplies power to the fuel cell 2. Then, an ultrasonic wave is oscillated, and the ultrasonic wave atomizes the chemical liquid (liquid chemical) in the chemical liquid container 8 and diffuses it into the atmosphere.
Other configurations are the same as those of the first and second reference examples described above.

The ultrasonic oscillation mechanism 7 includes a diaphragm 70 and an oscillator 71, for example, a piezoelectric oscillator, and the oscillator 71 is connected to a piezoelectric oscillation circuit (not shown) to oscillate ultrasonic waves using the fuel cell 2 as a power source. Ultrasonic waves are transmitted to the diaphragm 70.
The drug container 8 has a liquid absorption core 81 inserted into the container body 80, and supplies the drug to the diaphragm 70 through the liquid absorption core 81.
Since it is like this, the above-mentioned ultrasonic wave is transmitted to the vibration plate 70, and the chemical liquid in the container body 80 supplied to the vibration plate 70 is atomized by the above-described liquid absorption core 81 and sprayed to the atmosphere. That is, the liquid absorption core 81 is a chemical liquid supply means for supplying a chemical liquid to the vibration plate 70, and a liquid absorption core other than the liquid absorption core can be used. For example, dropping chemicals on the diaphragm.

A chemical container storage chamber 82 and an ultrasonic oscillation mechanism storage chamber 72 are formed in the first main body 5, and the ultrasonic oscillator storage chamber 72 is opened to the atmosphere through a spray port 73.

  Also in the above-described reference example, as shown in FIG. 8, the first main body 5 and the second main body 6 are connected to each other by a hinge 17 so as to be freely opened and closed. The fuel cell 2 (fuel body 20) can be exposed to the outside by opening.

According to the ultrasonic-type medicine diffusion device shown in FIG. 7, the chemical liquid atomized by the heat generated when the fuel cell 2 generates power can be heated to reduce the viscosity of the chemical liquid.
That is, the generated heat from the fuel cell 2 is transmitted from the communication hole 83 to the chemical liquid container 8 to heat the chemical liquid to be atomized, thereby reducing its viscosity and maintaining a viscosity range that can be sprayed constantly with a uniform particle size distribution. To be able to. Further, the generated heat can be effectively used for preventing clogging of the liquid absorbent core 81 and the liquid can be stably fed to the ultrasonic oscillation mechanism 7.

As described above, an apparatus for atomizing and spraying a chemical using ultrasonic waves is not limited to the above-described piezo-type spray apparatus, and the following apparatus may be used.

Secondly, a device that uses a vibration plate that is vibrated by ultrasonic waves in the spray cylinder and sucks and atomizes the chemical in the spray cylinder, specifically, an ultrasonic pump, a type that uses an ultrasonic transducer, It consists of a piezoelectric element, a liquid suction port, and a spray cylinder mechanism. An alternating voltage is applied to the piezoelectric element, the natural frequency of the piezoelectric element and the transducer are resonated, and the power is expanded and transmitted to the tip of the transducer. Atomized.
However, in consideration of the miniaturization of the apparatus and the ease of handling, a piezo-type spray apparatus and an ultrasonic pump-type spray apparatus are preferable.

  As for the spray pattern of the chemical liquid to be sprayed as described above, spraying may be performed continuously or spraying may be performed intermittently. When intermittent spraying is performed, it is effective for a particle diameter in which spray particles float for a long time, and it is possible to reduce power consumption. In addition, safety can be improved in controlling pests such as insecticides.

  The heating element 3 and the drug holding body 4, the blower 19, the drug holding body 4, the ultrasonic transmission mechanism 7 and the drug container 8 in each of the reference examples described above are means for diffusing the drug to the atmosphere using the fuel cell 2 as a power source.

Further, at startup, the lid 92 is removed to open the storage chambers 14 and 15, and the battery body 20 and the fuel tank 21 are exposed to the outside.

The fuel cell 2 (battery body 20) may be exposed on the lower surface of the device body 1.
