Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to an ultrasonic atomizer used for humidifying the upper respiratory tract, inhaling medicinal solutions, and the like.

(B) Conventional technology A conventional ultrasonic atomizer consists of a rigid metal body with a large diameter part and a small diameter part, with an ultrasonic vibrator fixed to the large diameter part and atomization in the small diameter part. A horn that integrally forms a diaphragm as a part, a bottle for storing the liquid to be atomized, and a water absorption band for guiding the liquid from the bottle to the horn, There is a device in which the liquid in the atomizing section is atomized by guiding the liquid through the water absorption band to the atomizing section of the horn and driving the ultrasonic vibrator.

Ultrasonic atomizers that use this type of water absorption band supply liquid using only capillary action, so the liquid cannot be supplied properly and efficiently, and the liquid may remain in the pot. However, in order to overcome these drawbacks, the inventors of this application developed an ultrasonic atomization system that supplies the liquid in the bottle using a separate water supply nozzle. I suggested a device.

(c) Problems to be Solved by the Invention When supplying liquid by using the water supply nozzle described above, since a liquid supply groove and an outside air introduction groove are provided, the bristles are affected by both the in-line phenomenon and the liquid's own weight. The advantage is that the liquid is supplied to the water at a high rate, but if the connection between the tip of the water supply nozzle and the atomizing surface of the Pawn is not appropriate, the liquid will definitely be absorbed by the Bohr. There is a problem in that liquid is not supplied to the atomizing surface of the atomizing section or liquid is discharged to the back side of the vibrating surface of the atomizing section, which adversely affects the driving circuit section.

This invention ensures the connection between the water supply nozzle and the Pawn atomization surface, and (+ (the supplied liquid is successfully applied to the atomization surface).

It is an object of the present invention to provide a Kawano '6M' FA converter that can be used without discharging atomized liquid on the back side.

(d) Means and operation for solving the problem The ultrasonic atomizer of the present invention divides the tip of the water supply nozzle into two parts with the liquid supply groove as the boundary, and one part is used to mist the water supply nozzle. In this ultrasonic atomizer, the tip of the water supply nozzle is in contact with the side of the water supply nozzle, and the other part is provided to protrude from the one part and extend to the surface of the atomization surface. Since one part is in contact with the side of the atomizing part of the pawn, the liquid will not get around to the back side of the vibrating surface. Also,
Since the other part of the nozzle tip protrudes more than the one part, that is, extends deeper than the edge of the atomizing part along the surface of the atomizing part, the liquid supplied from the liquid supply groove is
The liquid is guided between this other part and the atomizing part by capillary action and its own weight, and is reliably guided throughout the atomizing part.
