Problems solved by technology

[0002] Existing micropumps mostly use smaller motors to drive smaller fan blades, but because their specific volume cannot be further reduced, they still cannot be used in many occasions, such as being used to supply air to masks on masks

Embodiment Construction

[0015] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0016] As shown in the figure, the present invention includes a box body 1, electrode plates 2 with opposite polarities located at both ends of the box body and an agitating diaphragm 3 connected to the middle of the box body;

[0017] The agitating diaphragm has polarity, and the polarities of the two electrode plates are periodically switched to each other, driving the agitating diaphragm to agitate toward the two electrode plates respectively;

[0018] One end of the box body has a fluid outlet 4, and the box body is provided with a fluid inlet 5 on the side of the agitating diaphragm close to the fluid outlet, and the fluid inlet is provided with a check valve 6 that only allows fluid to enter; the fluid outlet is pro...

Abstract

The invention relates to the field of pumps, in particular to a mini pump device. The mini pump device comprises a box body, electrode plates which are located at the two ends of the box body and areopposite in polarity, and a drumming film connected to the middle portion of the box body. Since a mini pump does not need to be provided with a motor or a fan, the structure is not limited from the motor or the fan, the size can be smaller, and the requirement for smaller mini pump bodies can be met.

Description

technical field [0001] The invention relates to the field of pumps, in particular to a micropump device. Background technique [0002] Existing micro-pumps mostly adopt smaller motors to drive smaller fan blades, but they cannot be further reduced because of their specific volume, so they still cannot be used in many occasions, such as being used to supply air to masks on masks. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a micropump device. [0004] The present invention is achieved through the following technical solutions: [0005] A micropump device comprising a box body, electrode plates with opposite polarities located at both ends of the box body and an agitating diaphragm connected to the middle of the box body; [0006] The agitating diaphragm has polarity, and the polarities of the two electrode plates are periodically switched to each other, driving ...
