Micropore atomizing film Background technique:

In the prior art, the micropore atomized film is composed of a ring-shaped piezoelectric ceramic sheet and a circular metal film attached to the ceramic sheet. A bulge is formed in the center of the circular metal film on the micropore atomizing film, There is a uniform size of the micropore, the use of the atomizing film by applying voltage on the piezoelectric ceramic sheet to produce high-frequency vibration can make the liquid contact with the microporous atomized atomization.


Currently, on the market of small humidifier are using this micropore atomizing film, but micropore atomizing film in the liquid atomization process prone to bubbles, because the atomization of the smaller aperture, cannot be the bubble discharge, Which will affect the liquid atomization effect.


SUMMARY OF THE INVENTION To solve the above problems, the present invention provides a micropore atomization sheet capable of discharging bubbles generated during atomization.


The technical solution adopted by the utility model to solve the technical problem is a micropore atomized sheet comprising a ring-shaped piezoelectric ceramic sheet and a metal film coated on the ring-shaped piezoelectric ceramic sheet, wherein the metal film is arranged on the ring-shaped piezoelectric ceramic sheet Part of the ring is equipped with atomizing holes, the metal film has at least two different diameter atomizing holes. Further, as a modification of the present invention, a protrusion is formed on the inner portion of the ring-shaped piezoelectric ceramic sheet on the metal film, and each of the atomizing holes is located on the protrusion.


Further, as an improvement of the present invention, the atomizing hole is a conical hole, the two ends of the atomizing hole are respectively a water inlet end and a water outlet end, and the diameter of the water inlet end is larger than the diameter of the water outlet end. Further as an improvement of the utility model, the metal film is provided with connection holes on the portion coated with the annular piezoelectric ceramic sheet. Beneficial Effects of the Present Invention The micropore atomizing sheet of the present invention has at least two atomizing holes with different diameters. The atomizing holes with smaller diameters can produce better atomizing effect, and the atomizing holes with larger diameters can The bubbles generated by the atomization are discharged, so that the bubbles are discharged and the work of the atomized sheet is more stable and the humidification effect is better while the atomization effect is not affected.
