Description

Technical Field

[0001] This utility model relates to the field of peristaltic pump application technology, and in particular to a self-priming peristaltic pump with a snap-on cap. Background Technology

[0002] Currently, peristaltic pump head covers on the market mainly adopt two designs: screw fixing and flip-top structure. However, both methods have significant drawbacks. Screw fixing is cumbersome, requiring tools to tighten or loosen the screws each time it's installed or removed, which is time-consuming and labor-intensive, especially when frequently changing pipes or performing maintenance, greatly reducing work efficiency. Furthermore, after long-term use, the screws are prone to wear and even stripping, increasing maintenance costs. If the screws are not tightened properly, it may affect the pump head's sealing performance, leading to safety hazards such as liquid leakage. On the other hand, while the flip-top structure avoids the problem of frequent tool use, its mold costs are high. Customizing complex molds not only increases production costs but also extends the development cycle. At the same time, the complex structural design increases the difficulty of production and assembly. After prolonged use, the hinges and latches may age or break, affecting normal use.

[0003] Therefore, there is an urgent need in the market for a simpler, more economical, and reliable pump head cover solution to improve the user experience and the market competitiveness of products. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a self-priming peristaltic pump with a snap-on lid, including a peristaltic front cover, magnets, a support partition plate, and a peristaltic pump body. The support partition plate is disposed between the peristaltic front cover and the peristaltic pump body. Two magnets are provided, with the two magnets respectively disposed on both sides of the support partition plate.

[0006] Preferably, the interior of the gas-permeable front cover is provided with a first groove.

[0007] Preferably, the support partition plate is provided with a second groove, the second groove is at the same installation height as the first groove, and the two magnets are respectively placed in the first groove and the second groove, with the magnetic poles of the two magnets facing the support partition plate being opposite.

[0008] Preferably, the supporting partition plate is provided with a positioning block, which is located below the second groove.

[0009] Preferably, the inside of the peristaltic pump body is provided with a supporting positioning groove matched with the positioning block, and the peristaltic pump body and the supporting partition plate are fixed through the plug-in cooperation of the positioning block and the supporting positioning groove.

[0010] Preferably, the edge of the gas peristaltic front cover is fitted with the shell edge of the peristaltic pump body.

[0011] Therefore, the self-suction buckle cover peristaltic pump has the following beneficial effects:

[0012] (1) The magnetic attraction structure of the utility model can easily realize the installation and disassembly of the front cover without tools, significantly improves the operation efficiency, especially when frequently replacing the pipeline or maintaining, greatly saves the time and effort, and the magnetic attraction design can ensure the close fit between the front cover and the pump body, provide good sealing performance, and ensure the safe and stable operation of the equipment;

[0013] (2) Compared with the complex mold required by the flip cover structure, the magnetic attraction structure is designed to be simpler, reduces the mold manufacturing cost, shortens the development cycle, and also reduces the complexity of production and assembly, further reduces the overall production cost; the magnetic attraction part is usually made of high-strength and corrosion-resistant material, has a long service life, can maintain stable performance in various working environments, and reduces the daily maintenance demand;
