Description

Background

At present, there are two common champignon direct atomization devices in the market. One is to utilize compressed air to generate negative pressure at a venturi nozzle, extract liquid and atomize the liquid at the nozzle, the atomized gas-liquid mixture flows to an outlet through a spiral flow channel, and liquid drops are blown out by the compressed air and spread to an external space. There are two main disadvantages to the above approach: one, the noise is large, and the noise is not suitable for quiet environments such as bedrooms and hospitals; secondly, the atomized flow is difficult to accurately control, and the flow of the liquid with different viscosities under the same working condition has great difference, which can be dozens of times at most; in the other method, micropore piezoelectric ceramic is adopted for atomization, micropores with the order of tens to hundreds of microns are formed in an atomizing outlet, and liquid vibrates through the piezoelectric ceramic to form atomized substances which are diffused to an external space. There are three major disadvantages to this approach: the micropores are easy to be blocked, most atomization devices are used for generating water mist and are not suitable for atomizing essential oil/perfume/medicine; secondly, the atomization flow is basically fixed, and the flow is difficult to adjust by a user; thirdly, the liquid flows into the atomizing position by the self weight of the liquid, and the equipment cannot be toppled or inverted.

Referring to fig. 2 and 3, fig. 2 is a general structure diagram of the needle type piezoelectric ceramic driving mechanism in fig. 1; fig. 3 is an exploded view of fig. 2. In a specific embodiment, the piezoelectric ceramic assembly 20 employs a needle-type piezoelectric ceramic driving mechanism, in which the micro flow channel is a needle, and the needle-type piezoelectric ceramic driving mechanism specifically includes:

a base 24, said base 24 being used to support the entire mechanism and to dissipate heat;

the sheet body 22 is positioned on the base 24, and the sheet body 22 is fixedly connected with the needle 23;

the piezoelectric ceramic piece 21 is arranged on the piece body 22, when the piezoelectric ceramic piece 21 vibrates, the vibration is transmitted to the needle 23 through the piece body 22 and generates high-frequency vibration at the atomizing opening 231 of the needle 23, and then the liquid at the atomizing opening 231 is atomized.

The liquid inlet 241 is communicated with the hose 13, and a through micro channel is formed inside the base 24 and the amplitude variation vibration rod 23, and the inner diameter of the micro channel is between 0.4 and 1.2 mm. When the control board 40 drives the piezoelectric ceramic plate 22 to generate high-frequency vibration through the electrode 21, the vibration is transmitted to the atomizing opening 231 through the variable amplitude vibration rod 23, and thus the liquid in the atomizing opening 231 is atomized. The particle size of the atomized liquid is related to the drive frequency of the control plate 40. By adjusting the drive frequency, the particle size of the aerosol can be varied. The scheme adopts the driving frequency of 150-250KHz to realize that the diameter of most particles is between 5 and 15 microns.
