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.

Embodiment Construction

[0085] The present invention will be described in more detail below based on embodiments.

[0086] (implementation form 1)

[0087] FIG. 1 shows a perspective view of the appearance of a liquid atomizing device in Embodiment 1. As shown in FIG. The liquid atomizing device is composed of a main body 1 and a liquid supply assembly 2. The main body 1 has a battery housing 5 (refer to FIG. 3 ) and a circuit section inside, and the liquid supply assembly 2 is detachably installed on the Body part 1.

[0088] In FIG. 2 showing a partially cutaway perspective view of the liquid supply unit 2 and FIG. 3 showing a longitudinal sectional view inside the device, a primary liquid storage unit 10 for storing the liquid (medicine solution) to be atomized is disposed inside the device. A movable member 12 capable of moving up and down is mounted in a liquid-tight manner on the bottom of the primary liquid storage portion 10 , and the movable member 12 doubles as the bottom wall of the prim...

Abstract

A chemical stored in a primary liquid storage part (10) for storing the atomized chemical is filled by a specified amount to a secondary liquid storage part (16) through a liquid feed passage (18), a piston (20) is pushed by an operating rod (42) to turn on a power supply switch (46) when a liquid supply button (40) is slid to the left side, a valve (22) is moved leftward to open a liquid feed passage (24) as the chemical in the secondary liquid storage part (16) is pushed when the piston (20) is moved leftward, and the specified amount of chemical in the secondary liquid storage part (16) is fed to the atomizing part formed of a horn vibrator (30) and a mesh member (32) through the liquid feed passage (24) and a guide groove (26) and atomized there, whereby the atomization can be stabilized by making constant the liquid amount fed to the atomizing part at a low cost.

Description

technical field [0001] 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 [0002] 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 the liquid in the liquid storage part by the vibration of the vibration source and the mesh member. [0003] That is, the liquid in the liquid storage part enters the gap between the net member and the front end of the vibration source, and the vibration action of the net member and ...
