Referring to fig. 1 to 3, the portable anti-clogging water pump unit includes a housing 10, an impeller 20, and a power source 30. Wherein, the shell 10 is provided with a water suction port 11 and a water discharge port 12; a liquid flow path 13 is formed inside the housing 10 between the water suction port 11 and the drain port 12. The impeller 20 is arranged inside the shell 10 and close to the water suction port 11; the blades 21 of the impeller 20 are formed with cutting edges 22 on the edges of the sides facing the water intake 11. The power source 30 is used for driving the impeller 20 to rotate so as to enable the water suction port 11 to feed water.

Referring specifically to fig. 3, the pump may be composed of a plurality of portable anti-blocking water pump units, which are sequentially connected end to end from bottom to top. In some embodiments, the pump may be comprised of a single portable anti-clogging pumping unit.

Referring to fig. 3, when the pump includes a plurality of portable anti-clogging water pump units, water flows first from the water inlet of the first stage portable anti-clogging water pump unit located at the bottom of the pump body and then flows out from the water outlet of the first stage portable anti-clogging water pump unit. Then, water discharged from the water outlet of the first-stage portable anti-blocking water pump unit enters the second-stage portable anti-blocking water pump unit. Furthermore, it should be understood that the pump includes a plurality of portable anti-clogging pumping units, and is not meant to include only such units, but may include other types of pumping units.

It should be noted that, when the pump is placed in water to pump water, it is inevitable to suck some impurities in the water, which adversely affects the operation of the pump. In severe cases, the larger impurities may block the normal rotation of the water pump impeller, damaging the equipment, thereby increasing maintenance costs.

When the portable anti-clogging water pump unit is put into water during operation, the output shaft of the power source 30 outputs power, the impeller 20 is driven by the power source 30 to rotate, and water near the water suction port 11 is sucked into the casing 10, passes through the liquid flow passage 13 in the casing 10, and is discharged from the water discharge port 12. Referring to fig. 1 and 2, a power source 30 is accommodated inside the housing 10. In some embodiments, power source 30 is a permanent magnet variable speed motor.

The blades 21 of the impeller 20 are provided with cutting edges 22 on the edges facing one side of the water suction port 11, and along with the high-speed rotation of the impeller 20 during working, when sundries in water flow enter from the water suction port 11, the cutting edges 22 on the blades 21 can cut the sundries and are crushed into a plurality of split bodies so as to avoid interference on the normal operation of the pump.

Further, the impeller is a core component of the water pump, and the type of the impeller can be a closed impeller, a semi-open impeller and an open impeller. The closed impeller consists of blades, a front cover plate and a rear cover plate. The efficiency of the closed impeller is high and the manufacturing difficulty is high. Most applications are in centrifugal pumps.
