Problems solved by technology

[0002] When the general pump is exhausted, there are more or less problems with poor airtightness, noise in the airflow, and low air pressure.
Diaphragm pumps disclosed in the prior art have relatively mature functions and structures. If the exhaust pressure is to be increased, the structural changes will be large and the cost will be high.

Abstract

The invention discloses an upper cover for a pump and the pump. According to the pump, the upper cover is provided with an air outlet hole channel, and is used for covering an air bag of the pump, theair bag is provided with an air cavity facing the opening of the upper cover, and the upper cover is provided with a pressurization bulge which is suitable for extending into the air cavity. According to the upper cover for the pump, the pressurization bulge can cooperate with the compression of the air cavity after reasonable molding so as to reduce the amount of residual gas and to increase exhaust pressure; and the pressurization mode is simple and reasonable in structure, and the upper cover is relatively low in cost.

Description

technical field [0001] The invention relates to the technical field of pump body equipment, in particular to an upper cover for pumps and a pump. Background technique [0002] Ordinary pumps still have the problems of poor airtightness, noise in the airflow, and low air pressure when exhausting. The diaphragm pumps disclosed in the prior art have relatively mature functions and structures. If the exhaust pressure is to be increased, the structure needs to be changed greatly and the cost is relatively high. Contents of the invention [0003] The purpose of this application is to provide an upper cover for a pump, which is beneficial to increase the exhaust pressure of the pump, and has little structural modification and low cost. [0004] Another object of the present invention is to provide a pump with the above cover. [0005] According to the upper cover for the pump of the present invention, the upper cover is provided with an air outlet channel, and the upper cover i...
