Piezoelectric ceramic atomizer plate

Abstract

The invention relates to a piezoelectric ceramic atomizer plate which comprises a piezoelectric ceramic chip, wherein the upper portion of the piezoelectric ceramic chip is in a circular truncated cone shape, and the lower portion of the piezoelectric ceramic chip is cylindrical. A front round electrode is arranged on the bottom face of the piezoelectric ceramic chip, and a reverse round electrodeand a reverse electrode connecting wire are arranged on the top face of the piezoelectric ceramics chip. A reverse electrode welding area is connected with the reverse round electrode through the reverse electrode connecting wire to achieve conduction. A reverse welding area is connected with the front round electrode through a side face connecting wire to achieve conduction. The welding areas are arranged on circular truncated cone slopes of the piezoelectric ceramics chip, direct influence of the welding areas on electrode oscillation can be effectively avoided, the atomizing effect has noloss and is not affected, and meanwhile, soldering tin can be prevented from diffusing to the surface of the round electrode. In addition, due to the fact that the upper portion of the piezoelectric ceramic chip is in a circular truncated cone shape, and the lower portion of the piezoelectric ceramic chip is cylindrical, the effect gathering effect of products can be effectively motivated, and a good atomizing effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of piezoelectric ceramic atomizing sheets, in particular to a piezoelectric ceramic atomizing sheet. Background technique [0002] Piezoelectric ceramic atomizers use a certain stable voltage to oscillate out the frequency. According to the thickness of the product, the oscillation frequency is basically controlled between 1.53 and 3.0MHZ, which has exceeded the hearing range of the human ear. no harm. When the piezoelectric ceramic atomizer works, it throws up and breaks up the molecular structure of liquid water to produce a natural and elegant water mist, which can be realized without heating or adding any chemical reagents. In the prior art, piezoelectric ceramic atomizing sheets are mainly used in the fields of indoor humidification, indoor aromatherapy, dust removal, etc., and the products are required to have small atomized particles and a large amount of atomization. However, because the load forme...

Problems solved by technology

However, because the load formed during welding will compress the vibration of the atomizer, the larger the solder joint, the more serious the impact will be, and the more the vibration of the atomizer will be restrained, which will greatly affect the atomization amount of the product. And the atomization effect, there are often phenomena such as low water cut-off sensitivity, small amount of atomization, and unstable atomization process.
