Description

Technical Field

[0001] The utility model belongs to the technical field of peristaltic pumps, and in particular relates to a portable large-flow peristaltic pump. Background Art

[0002] Peristaltic pumps consist of three parts: the drive, the pump head and the hose. The main competitive advantages of peristaltic pumps are that the fluid is isolated in the pump tube, the pump tube can be quickly replaced, the fluid is reversible, it can run dry, and the maintenance cost is low. The peristaltic pump is like squeezing a hose full of fluid with your fingers, and the fluid in the tube moves forward as the fingers slide forward. The peristaltic pump is also based on this principle, but the fingers are replaced by rollers. The fluid is pumped by alternately squeezing and releasing the elastic delivery hose of the pump. Just like squeezing a hose with two fingers, as the fingers move, negative pressure is formed in the tube, and the liquid flows.

[0003] A portable peristaltic pump disclosed in announcement number CN216975188U includes a pump housing, a pump head and a control panel are provided at the front end of the pump housing, a hose is passed through the pump head, a fixed block is provided at the side end of the pump housing, a screw groove is provided on the fixed block, a slide groove is provided at the side end of the pump housing, a slide seat is slidably connected in the slide groove, a slide block is provided on the slide seat, a groove is provided on the fixed block and the slide block, a damping buckle sleeve is provided in the groove, a handle is provided at the top of the pump housing, and a threaded column is provided on the fixed block. The two ends of the hose can be bent into the damping buckle sleeves on the fixed blocks on both sides, and the slide block is slid downward and locked by the threaded column, and then the handle can be held to carry the peristaltic pump as a whole, which improves the overall convenience and aesthetics of the peristaltic pump as a whole, and by providing a symmetrical trapezoidal waterproof seat structure with a corrosion-resistant and anti-skid layer, the waterproof, anti-skid and corrosion resistance of the peristaltic pump when it is placed on a workbench for work is improved.
