Description

Technical Field

[0001] The utility model relates to the technical field of suction pumps, in particular to an anti-clogging suction pump. Background Art

[0002] A suction pump is a device used to extract liquid or gas. It is usually driven by an electric motor and generates negative pressure through a mechanical device, so that the liquid or gas is drawn into the pump and then transmitted to the target location through a pipe or pipe system. However, due to impurities such as solid particles, fibers and dirt that may exist in the liquid or gas, the suction pump is often prone to blockage. Blockage will cause the pump efficiency to decrease or even cause damage to the suction pump. Therefore, it is necessary to design an anti-blocking suction pump.

[0003] In order to prevent blockage, some existing suction pumps will fix a filter device at the water inlet of the suction pump to filter solid particles and other debris contained in the liquid. However, as the use time increases, more debris will accumulate on the surface of the filter device, causing blockage on the surface of the filter device, which will also cause the suction pump to malfunction and even burn its internal motor, reducing the practicality of the device. Most of the existing filter devices are filter screens, which are fixed to the water inlet of the suction pump by multiple bolts. Therefore, when there are too many impurities on the filter screen and it needs to be cleaned, multiple bolts must be loosened for disassembly, which makes the operation more cumbersome and reduces work efficiency.
