Problems solved by technology

Most of the existing peristaltic pump heads use a plurality of rollers to circulate and squeeze the hose to transport the fluid. During the delivery process, because the rollers continue to slide and rub against the hose, the hose is constantly replaced as needed. , which greatly increases the cost consumption

Abstract

The invention relates to a novel peristaltic pump head which comprises a miniature motor, a pump head base, a roller assembly and a pump head upper cover. A groove is formed in the upper surface of the pump head base, the roller assembly is positioned in the groove in the pump head base, the pump head upper cover is connected to the upper side of the pump head base, the roller assembly is positioned between the pump head base and the pump head upper cover, a through hole is formed in the center of the groove, a shaft extension end of the miniature motor penetrates the through hole to be meshed with the roller assembly, a first gear is arranged at the shaft extension end of the miniature motor, the miniature motor is connected with the roller assembly by the first gear, and two 'U'-shaped pipe access openings are formed in a side of the pump head upper cover. The novel peristaltic pump head has the advantages that squeezing conveying can be carried out by the aid of rolling friction instead of sliding friction, and accordingly purposes of prolonging the service lives of hoses and reducing the cost can be achieved.

Description

technical field [0001] The invention relates to a pump component, in particular to a novel pump head of a peristaltic pump. Background technique [0002] Peristaltic pumps are a type of positive displacement pumps and are mainly used for the distribution and delivery of fluids. When the pump head of the peristaltic pump is working, the roller rotates, squeezes the elastic hose, and delivers the fluid through the elastic hose. Most of the existing peristaltic pump heads use a plurality of rollers to circulate and squeeze the hose to transport fluid. During the delivery process, because the rollers continue to slide and rub against the hose, the hose is constantly replaced as needed. , greatly increasing the cost consumption. Contents of the invention [0003] The technical problem to be solved in the present invention is to use rolling friction instead of sliding friction to carry out squeezing and conveying, so as to prolong the service life of the hose and reduce the co...
