Abstract

The invention relates to the technical field of vacuum pumps, and discloses a miniature vacuum pump which comprises a motor. A base is installed at the top of the motor, the surface of the base is communicated with an air inlet, and an eccentric wheel is installed in the base. According to the miniature vacuum pump, the purpose of noise reduction is achieved by omitting the installation of an umbrella-shaped rubber part, air pressure in a tower-shaped air bag can be discharged through a lower cover and an air nozzle without using the umbrella-shaped rubber part, thus, the situation that noise is generated by opening and closing of the umbrella-shaped rubber part cannot occur any more, and then the decibel value of the vacuum pump during working is reduced. The purpose of convenient installation is achieved by arranging the bottom of an inner cavity of the eccentric wheel and the bottom end of a connecting rod into a hemispherical shape, the connecting rod can be directly clamped to the eccentric wheel, thus, the effect of cooperative use of a steel needle and steel balls is achieved, then, the step of installing the steel needle and the steel balls is omitted, the installation process is simplified, and the installation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of vacuum pumps, in particular to micro vacuum pumps. Background technique [0002] A micro vacuum pump is a micro vacuum pump that can form a negative pressure at the suction port of the micro pump to allow the gas to be pumped out under the action of atmospheric pressure. It is called a micro vacuum pump. And the miniature air pump that can generate negative pressure is also often called "miniature negative pressure pump" and "miniature vacuum pump". [0003] When today’s micro vacuum pumps are in use, the umbrella-shaped rubber piece on the top of the airbag will open and close as the airbag vents and inhales, and every opening and closing of the umbrella-shaped rubber piece will beat the air nozzle and the umbrella-shaped mounting piece. As a result, noise will be generated, and today's micro vacuum pumps need to install the rotating steel ball and the steel needle separately when installing, first put ...
