The invention provides a mute exhaust structure and a corresponding micro air pump. The mute exhaust structure comprises a pump shell and an air outlet valve body, wherein the pump shell comprises an air exhaust seat and a valve fixing seat; the air exhaust seat and the valve fixing seat are connected to form a valve cavity; an air outlet through hole communicating the valve cavity and an air outlet cavity is formed in the valve fixing seat; an air outlet opening communicating the valve cavity and the external space is formed in the air exhaust seat; the air outlet valve body is connected to the air outlet through hole and is used for controlling one-way air outlet; a connecting hole used for being connected with the air outlet through hole is formed in one end of the air outlet valve body; a long-strip-shaped air outlet hole is formed in the other end of the air outlet valve body; air in the air outlet cavity is pressed out to the external space through the air outlet hole of the air outlet valve body; and the air outlet valve body can automatically seal the air outlet hole through contraction. According to the mute exhaust structure, the air outlet hole is automatically sealed through contraction of the mute exhaust structure, the exhaust efficiency is high, the reverse sealing effect is good, and the noise is low.
Description
[0001] This application is a divisional application, the application number of the original application is: "202011479983.3", the application date is: "December 15, 2020", and the name of the invention is: "Micro Air Pump". technical field [0002] The invention relates to the field of air pumps, in particular to a quiet exhaust structure and a corresponding micro air pump. Background technique [0003] Micro air pump refers to a gas conveying device with small size and gaseous working medium, which is mainly used for gas sampling, gas circulation, vacuum adsorption, vacuum pressure maintaining, pumping, pumping, pressurizing and other purposes. At present, there are many kinds of air pumps on the market, which generally include power components, piston cylinder components, intake valve bodies, gas outlet valve bodies and corresponding multiple fixed seats, and the power components are used to drive and control the gas to enter through the intake valve body in one direction. ...
