Liquid level induction system of ultrasound atomising device

Abstract

The invention relates to a liquid level induction device of an ultrasonic atomizing device, which comprises an atomizer and a liquid receiving container, wherein, the atomizer comprises a shell and anenergy conversion sheet; and the atomizer is detachably fixed on the bottom of the liquid receiving container. The device is characterized by comprising an electrode plate fixed on the side wall of the liquid receiving container; a control circuit of the atomizer is connected with the electrode plate by an electrical conductor. The electrode plate takes a circular shape or a sheet plate shape, and is arranged in the side wall body and the inner surface or outer surface of the side wall body of the liquid receiving container. The electrode plate is arranged above the atomizer, namely, the position outside an atomization cavity, so that the ultrasonic atomizing device manufactured by the technical proposal of the invention not only can accurately control the liquid level, but also is convenient for cleaning the energy conversion sheet. Therefore, the device can be widely applied to devices with atomized liquid, such as water, aromatizer, lotion, liquid medicine, liquid preparation, alcohol, etc.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic atomizers, in particular to the technical field of liquid level detection in ultrasonic atomizers. Background technique [0002] The ultrasonic atomization device used for humidification, fragrance, sterilization or decoration in daily life can atomize the liquid contained in the liquid container through the ultrasonic wave generated by the ultrasonic generator, so as to realize its atomization function. In these atomization devices, automatic liquid level detectors and controllers are generally provided, so that the liquid level of the atomized liquid can be automatically detected, especially when the liquid is about to run out, the work must be stopped immediately, otherwise the high-speed vibrating The transducer sheet may not be able to dissipate heat reliably due to lack of water and be damaged by dry burning. Therefore, in the atomization device that automatically controls the atomizatio...

AI Technical Summary

Problems solved by technology

[0003] 1. The plate of electrode A cannot be made too high or too large. Too small an area will limit its effective area and thus limit the capacitance of the capacitor. It requires high conductivity of water quality.

If the capacitance of the capacitor is too small, and the distributed capacitance formed by other factors such as wiring will have a greater impact on the circuit part, which will eventually reduce the stability of the circuit.

If the effective area of ​​the plate is made larger, the liquid storage capacity of the entire atomization chamber will be reduced, and the effective work of the transducer will be hindered.

[0004] 2. The liquid level sensor 92 of this structure can only be placed in the atomization chamber together with the atomizer, and the mist-liquid mixing column generated when the atomizer is working directly impacts the liquid level sensor 92 on the side, thereby affecting the electric current. The capacity will cause a certain deviation, which will easily cause the atomizer to flash between working and stopping, that is, false liquid level

[0005] 3. Since the liquid level sensor 92 of this structure can only be placed in the atomization chamber together with the atomizer, it will not only affect the appearance of the entire atomization chamber, but also affect the appearance of the atomization chamber, the upper surface of the housing and the transducer sheet. inconvenient cleaning
