Description

Technical Field

[0001] The utility model relates to the technical field of peristaltic pumps, and more specifically to a peristaltic pump with a small-volume multifunctional pump head. Background Art

[0002] Peristaltic pump is a pumping device with the characteristics of constant flow pump and hose pump, mainly composed of three parts: driver, pump head and elastic hose. Its characteristics are that it can isolate the fluid in the pump tube, quickly replace the pump tube, allow the fluid to reverse, and can run dry.

[0003] Peristaltic pumps are widely used in biomedical fields, food and beverage industry, chemical industry, environmental protection field and pharmaceutical industry due to their characteristics of pollution-free, high precision, low shear force, good sealing, simple maintenance and quantitative pumping. At present, the pump tube of traditional peristaltic pumps is usually an integral long tube structure, that is, the two ends of the long tube are placed at the input position and the output position respectively. Since the tube is prone to damage under long-term use, it needs to be replaced regularly. However, when the long tube structure is replaced, only the pumping area is prone to damage, and overall replacement is prone to waste. In addition, the rotor of the traditional peristaltic pump is generally used with a pump tube of a specific size, which has high limitations and weak functionality. In view of this, we propose a peristaltic pump with a small volume and multifunctional pump head. Utility Model Content
