Description

Technical Field

[0001] The invention relates to a pump, in particular to a piezoelectric micro air pump with ozone and negative ion functions, which utilizes ozone for sterilization, disinfection or for increasing the negative ion content in the air. Background Art

[0002] Piezoelectric micro air pumps have the advantages of stable air pressure, small size, high efficiency, low noise and power consumption. They have been widely used in environments that require small size, high efficiency and high noise.

[0003] Due to its strong oxidizing property, ozone has been widely used in many fields such as disinfection, air purification, water treatment, food preservation and disease treatment.

[0004] In the prior art, ozone generation is based on the corona discharge method, and air ionization generates ozone. The ozone generator is composed of a generating plate control circuit and an ozone generating plate. The control circuit controls the operation of the ozone generating plate. After the air flows through the ozone generating plate, part of the air generates ozone.

[0005] Negative ions are called "air vitamins" and are extremely beneficial to human health.

[0006] The negative ion generator is composed of a switching power supply and a high-voltage discharge emitter head. The high-voltage discharge emitter head discharges in space to generate negative ions in the air.

[0007] In the prior art, the ozone generator or the negative ion generator is separately provided. In order to realize the flow of air containing ozone or negative ions, an air pump needs to be provided at the air inlet of the ozone generator or the negative ion generator. The disadvantages of the prior art of selecting different air pumps to be connected with the ozone generator or the negative ion generator are: since ozone is extremely unstable, the pressure size, pressure stability and flow rate of the pressurized air generated by the air pump cannot be reasonably and accurately matched with the ozone generator and the negative ion generator, and the production efficiency of ozone or negative ions in the gas is low, the structure is complex, the volume is large and the scope of application is small. Summary of the invention

[0010] The pump body is a dual-chamber structure consisting of a pressure gas generating chamber and a pressure gas processing chamber. The pressure gas generating chamber and the pressure gas processing chamber are connected through an outlet control valve. The pressure gas generating chamber is connected to the atmosphere through an inlet control valve. The pressure gas processing chamber is provided with an exhaust port.

[0011] A ceramic piezoelectric vibrator is arranged in the pressure gas generating chamber.

[0012] An ozone generating plate or a negative ion generator is fixedly supported in the pressure gas treatment chamber.

[0013] The pump body cover comprises: a pressure chamber pump cover and a processing chamber pump cover.

[0014] The pressure chamber pump cover is fixedly connected to the pressure gas generating chamber on the pump body to form a closed pressure gas generating chamber structure.

[0015] The processing chamber pump cover is fixedly connected to the pressure gas processing chamber on the pump body to form a closed pressure gas processing chamber structure.

[0016] The invention has the following beneficial effects: simple structure, small overall volume, low working noise, low cost, high efficiency of ozone or / and negative ion generation. The invention integrates a piezoelectric micro air pump, an ozone generator or / and a negative ion generator into one, thus expanding the application scope of the piezoelectric micro air pump, the ozone generator or the negative ion generator.

DETAILED DESCRIPTION

[0023] Referring to the attached drawings, a piezoelectric micro air pump with ozone and negative ion functions is shown, and the micro pump comprises: an electric control circuit, a pump body, a ceramic piezoelectric vibrator, a pump body cover, an air inlet control valve, and an air outlet control valve.

[0024] The pump body 1 is a dual-chamber structure consisting of a pressure gas generating chamber 1-1 and a pressure gas processing chamber 1-2. The pressure gas generating chamber 1-1 and the pressure gas processing chamber 1-2 are connected via an outlet control valve 2. The pressure gas generating chamber 1-1 is connected to the atmosphere via an inlet control valve 3. The pressure gas processing chamber 1-2 is provided with an exhaust port 4.

[0025] A ceramic piezoelectric vibrator 5 is disposed in the pressure gas generating chamber 1 - 1 .

[0026] An ozone generating plate 6 or a negative ion generator 7 is fixedly supported in the pressure gas treatment chamber 1 - 1 .

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

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

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

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

[0031] The pressurized air passes through the ozone generating plate 6 or the high-voltage discharge emission head 7 - 1 of the negative ion generator 7 in the pressure gas treatment chamber 1 - 2 to generate ozone or negative ions, and then is output from the exhaust port 4 .

[0032] According to the pressure size, pressure stability and flow rate of the pressure gas generated by the pressure gas generating chamber 1-1, a reasonable and accurate matching design is carried out with the ozone generator and / or the negative ion generator to achieve high efficiency of ozone generation and / or negative ion generation in the flowing pressure gas, increase the content (or density) of ozone and / or negative ions in the pressure gas and low energy consumption.

[0033] Based on the working principle and structural characteristics of the piezoelectric micro air pump, the present invention creatively designs the piezoelectric micro air pump and the ozone generator and / or the negative ion generator into an integrated structure, thereby solving the technical deficiencies such as complex structure, difficult sealing, large size and noise, and low density of ozone and / or negative ions caused by the connection between the air pump and the ozone generator and / or the negative ion generator.

[0034] According to a large number of experimental results, when a piezoelectric micro air pump is used together with an ozone generator and / or a negative ion generator to supply air, the content (or density) of ozone or / and negative ions in the pressure gas measured at the output end is higher than that of an air pump using other structures. At the same time, the total energy consumption of the integrated structure of the present invention is greatly reduced.

[0035] In the embodiment of the present invention, in order to expand the scope of use, the pressure gas treatment chamber 1-1 is fixedly provided with an ozone generating plate 6 and a negative ion generator 7. The present invention has a multifunctional piezoelectric micro air pump for oxygen pump, ozone generator and negative ion generator.

[0036] In the embodiment of the present invention, the high-voltage discharge emission head 7-1 of the negative ion generator 7 is arranged in the pressure gas processing chamber 1-1.

[0037] In the embodiment of the present invention, the negative ion generator (7) is arranged on the processing chamber pump cover (8-2). By replacing the processing chamber pump cover (8-2), the negative ion generating function of the piezoelectric micro air pump can be increased or decreased, which facilitates the standardized design of the product.

[0038] In an embodiment of the present invention, the electronic control circuit includes: a switching power supply, a main control circuit board, a display circuit, an air pump drive circuit, an ozone generator drive circuit and a negative ion generator drive circuit. The switching power supply is electrically connected to the display circuit, the air pump drive circuit, the ozone generator drive circuit and the negative ion generator drive circuit through the main control circuit board.
