[0023] Referring to the drawing, a piezoelectric micro-pump with ozone and negative ion functions, the micro-pump comprises: an electric control circuit, a pump body, a ceramic piezoelectric vibrator, a pump body cover, a gas inlet control valve, and a gas outlet control valve.

[0024] The pump body 1 is a double-cavity structure composed of a pressure gas generating cavity 1-1 and a pressure gas processing cavity 1-2, the pressure gas generating cavity 1-1 and the pressure gas processing cavity 1-2 are in communication through the gas outlet control valve 2, the pressure gas generating cavity 1-1 is in communication with the atmosphere through the gas inlet control valve 3, and the pressure gas processing cavity 1-2 is provided with the exhaust port 4.

[0025] The ceramic piezoelectric vibrator 5 is arranged in the pressure gas generating cavity 1-1.

[0026] The ozone generating plate 6 or the negative ion generator 7 is fixedly supported in the pressure gas processing cavity 1-2.

[0027] The pump cover comprises a pressure cavity pump cover 8-1 and a processing cavity pump cover 8-2.

[0028] The pressure cavity pump cover 8-1 is fixedly connected with the pressure gas generating cavity 1-1 on the pump body 1, so as to form a closed pressure gas generating cavity 1-1 structure.

[0029] The processing cavity pump cover 8-2 is fixedly connected with the pressure gas processing cavity 1-2 on the pump body 1, so as to form a closed pressure gas processing cavity 1-2 structure.

[0030] The high-frequency vibration of the ceramic piezoelectric vibrator 5 in the pressure gas generating cavity 1-1 generates pressure air, which enters the pressure gas processing cavity 1-2 through the gas outlet control valve 2.

[0031] The pressure air generates ozone or negative ions after passing through the high-voltage discharge emitting head 7-1 of the ozone generating plate 6 or the negative ion generator 7 in the pressure gas processing cavity 1-2, and is output by the exhaust port 4.

[0032] According to the pressure gas pressure size, pressure stability and flow generated by the pressure gas generating cavity 1-1, the ozone generator or / and the negative ion generator are reasonably and accurately matched and designed, so as to realize high efficiency of ozone generation or / and negative ion generation in the flowing pressure gas, improve the content (or density) of ozone or / and negative ions in the pressure gas, and reduce energy consumption.

[0033] Based on the working principle and structural characteristics of piezoelectric micro air pumps, this utility model creatively integrates piezoelectric micro air pumps with ozone generators and / or negative ion generators into a single structure, solving the technical shortcomings of connecting air pumps with ozone generators and / or negative ion generators, such as complex structure, difficult sealing, large size and noise, and low ozone and / or negative ion density.

[0034] Extensive experimental results show that when using a piezoelectric micro air pump and an ozone generator and / or a negative ion generator to supply air, the ozone or / negative ion content (or density) in the pressure gas measured at the output end is higher than that of air pumps using other structures. At the same time, the overall energy consumption is greatly reduced by using the integrated structure of this utility model.

[0035] In this embodiment of the invention, to broaden its application range, an ozone generating plate 6 and a negative ion generator 7 are simultaneously fixedly installed inside the pressure gas processing chamber 1-1.
