[0002] Peristaltic pump is a liquid delivery device with controllable flow rate. It has the advantages of high delivery accuracy, strong corrosion resistance, small shearing effect, simple operation and easy maintenance. It is used for water supply and drainage of sweepers, medical pumps for drug delivery, and inkjet printers. Therefore, it is widely used in scientific research, pharmaceuticals, chemicals, environmental protection, beverages, food, printing and other fields.

[0003] A peristaltic pump is like squeezing a fluid-filled hose with your fingers. As your fingers slide forward, the fluid moves forward. The peristaltic pump works on the same principle, except that the fingers are replaced by rollers. The fluid is pumped by alternately squeezing and releasing the pump's elastic delivery hose.

[0004] During operation, the existing peristaltic pump needs to reciprocately squeeze the internal hose to achieve the fluid movement effect, which reduces the service life of the hose and requires regular replacement. The traditional peristaltic pump needs to remove the pump cover and then disassemble and remove the internal hose, which is inconvenient overall and has low replacement efficiency. Therefore, it does not meet the existing needs. In this regard, we propose a peristaltic pump for a sweeper. Utility Model Content
