Abstract
A linear cleaning peristaltic metering pump includes a pump body, a hose fixing accessory and an anti-backflow accessory. The hose fixing accessory is configured for arranging a working hose. The anti-backflow accessory is configured for clamping and loosening the working hose. The pump body is configured for performing reciprocating motion to clamp or loosen the working hose, thereby realizing a pumping effect by metering pump. The anti-backflow accessory is in cooperation with the pump body. The pump body comprises a roller lifting assembly, a roller hose-pressing assembly, a pump body outer cover assembly and a power transmission part. The power transmission part is configured for driving the roller lifting assembly to perform lifting linear motion, thereby driving the roller hose-pressing assembly to move and to clamp or loosen the working hose.
