Description

[Detailed description of the invention] The present invention relates to an improvement of an ultrasonic atomization device that atomizes liquid in an atomization tank by ultrasonic irradiation. The present invention provides an ultrasonic atomization device in which the temperature of the mist to be discharged can be controlled.

Hereinafter, the present invention will be described in detail based on embodiments and with drawings.

Fig. 1 is a perspective view of the ultrasonic atomization device implementing the present invention, Fig. 2 is an explanatory view of important points seen from the side,
Figure 3 is also an explanatory diagram of important points seen from the rear.
The simple configuration of this ultrasonic atomizer is that an ultrasonic vibrator 2 is provided in the main body 1 of the ultrasonic atomizer, and the ultrasonic vibrations are injected into an atomization tank 4 using water 3 contained in a container. The liquid drug 5 is indirectly communicated. The drug 5 that has been converted into fine particles by ultrasonic vibration is atomized in the atomization tank 4, and since the atomized particles are heavier than air, they are attached to the lid 6 provided at the top of the atomization tank 4. No injection is made from the injection tube 7. For this reason, wind pressure is applied to spray the mist particles to the outside (toward the oral cavity). For this purpose, as can be seen in FIG. 2, a center fan 8 is provided in the main body 1 of the ultrasonic atomizer, and as the fan 8 rotates, outside air is sucked in from the ventilation window 9 and passed through the wind barrel 10 and the hollow pipe handle 11. The air is sent into the atomization tank 4 through a connecting pipe 12 that is connected to a pipe handle 11 and houses an outside air purification filter 13 therein (in the figure, the arrow indicates the direction of air blowing). The drug particles are injected from the injection tube 7 by the wind pressure of the outside air blown in this way. At this time, the outside air sent into the atomization tank 4 comes into contact with the residual chemical liquid 5 generated by the ultrasonic vibration and cools it. Furthermore, as can be seen in FIG. 3, the outside air taken in by the center fan 8 is extracted from electric circuit components such as the power transformer 14, the power transistor 15, the ultrasonic vibrator 2, etc. that generate a large amount of heat in the ultrasonic generator installed in the main body 1. Directed for cooling. (Arrow a in FIG. 3 indicates the direction of outside air movement toward the atomization tank 4, and arrow b indicates the direction of movement of outside air passing through the main body 1.) In this way, the atomization described in the latter half of the configuration of the ultrasonic atomization device described above By adopting a mechanism that blows air into the tank 4 and blows air to cool the inside of the main body 1, the ultrasonic atomizer can spray particle medicine, and at the same time, one center fan can spray the medicine. Injection, cooling of the medicine, and cooling of the heat source can be performed simultaneously.

Further, in the present invention, in the ultrasonic atomization device, a temperature control device 16 for making the temperature of the drug particles injected from the injection barrel 7 approximately equal to body temperature is incorporated in the ventilation mechanism, and When using the ultrasonic atomizer in a season when there is a large difference between the ambient temperature and body temperature, stimulation to the human body due to the temperature of the mist sprayed from the spray cylinder 7 can be alleviated.

As described above, according to the present invention, since a temperature control device is provided in the air flow path from the air blower to the atomization tank, it is possible to control the temperature of the mist being sent out, making it possible to achieve practical ultrasonic atomization. The device may be provided.
