[0002] A magnetic pump is a pump that uses a magnetic transmission to achieve contactless torque transmission, thereby replacing dynamic seals with static seals to achieve a completely leak-free pump. When the magnetic pump is in use, a filter mechanism is required to filter out impurities in the liquid to prevent them from being damaged.

[0003] A Chinese patent with publication number CN 114810681 B discloses a fluorine-lined magnetic pump with an impurity filtering mechanism. The key points of its technical solution are: it includes a fluorine-lined magnetic pump body, one end of the fluorine-lined magnetic pump body is connected to a water inlet pipe, and the fluorine-lined magnetic pump body is provided with a fixed bin at one end close to the water inlet pipe. The internal fixed sleeve of the fixed bin is provided with a fixed ring. The larger impurities, debris and fibers in the liquid medium are intercepted by the filtering component, and the impurities in the liquid medium are accumulated, thereby realizing the filtration of the liquid medium, while facilitating the cleaning of the staff, and ensuring that the impurities in the liquid medium will not cause damage to the impeller in the fluorine-lined magnetic pump body, thereby increasing the service life of the impeller. The debris and fibers in the liquid medium are intercepted in turn by the second filter screen, the third filter screen and the polypropylene filter membrane, thereby ensuring that the liquid medium entering the water inlet pipe can be purer, so that no debris or fibers will remain in the liquid medium.

Since the filtering mechanism cannot be easily disassembled, the convenience of disassembling and cleaning the device is poor.
