Liquid atomizer

Abstract

The invention relates to a liquid atomizing device, which comprises a liquid storage room, a measuring room, an atomizing portion, a piston, a piston driving portion, an impedance checking device and a vibrating stopping device, the liquid storage room is used to store liquid, the measuring room feeds in the liquid with specified amount from the above liquid storage room through a liquid feeding hole, the atomizing portion comprises a network component which is used to atomize the above liquid which is fed in from the above measuring room through the liquid feeding hole and an oscillator, the piston is used to thrust the above liquid in the measuring room through the closed above liquid feeding hole, thereby the above liquid is supplied to the above atomizing portion through the liquid feeding hole, the piston driving portion is used to drive the above piston, the impedance checking device is used to check the impedance of the above oscillator, and the vibrating stopping device is used to stop the vibration of the above oscillator relative to the impedance which is checked by the impedance checking device and is in the status under a regulated value.

Description

[0001] The application of the present invention is a divisional application of the invention application with the filing date of October 4, 2001 (the international filing date), the application number being 01816904.X, and the title of the invention being "liquid atomizing device". technical field [0002] The present invention relates to a liquid atomizing device having a liquid feeding mechanism for stably supplying a constant amount of liquid each time. Background technique [0003] For example, an existing ultrasonic liquid atomizer for portable use generally has a liquid storage part for storing liquid (medicine liquid), a vibration source (such as an ultrasonic horn vibrator) for supplying the liquid in the liquid storage part to the front end, and a vibrating source (such as an ultrasonic horn vibrator) arranged in contact with the liquid storage part. The mesh member having a plurality of fine pores on the end surface of the front end of the vibration source atomizes ...

AI Technical Summary

Problems solved by technology

However, in fact, the degree of inclination when the device is used, vibration from the outside, the residual liquid in the liquid storage part, etc. are affected, and the supply amount to the atomization part is not constant, and the atomization is unstable in many cases.

Such atomization instability is not ideal for suction therapy where a certain amount of high-concentration liquid medicine is inhaled each time, since the quantitative spray cannot be stabilized.
