Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of swimming pool cleaning equipment, especially to a pool sewage suction device. BACKGROUND

[0002] In the prior art, the pool sewage suction device is similar to the principle of a water pump. A motor rotates to drive an impeller to rotate at high speed. Under the action of centrifugal force generated by the high-speed rotation of the impeller, water in the flow passage of the sewage suction chamber is thrown to the water outlet around the impeller when passing through the impeller, and a vacuum is formed at the impeller. The water in the pool is again sucked into the sewage suction chamber under the action of the pressure difference, and the sand, fallen leaves and other impurities in the pool are also sucked in at the same time. The core part of the pool sewage suction device is composed of a sewage suction chamber, a motor chamber and an impeller, which are arranged in an up-down manner. The sewage suction chamber is located at the end of the product, and the impeller is located between the sewage suction chamber and the motor chamber. The impeller is connected to the output shaft of the motor. A filter device is arranged in the sewage suction chamber. The filter device is located at the front end of the sewage suction chamber. The motor chamber is composed of a motor, a circuit, a switch and the like. Several drain holes are arranged around the impeller. When working, water and dirt enter from the opening position of the sewage suction chamber, pass through the filter device of the sewage suction chamber, and the dirt is adsorbed in the filter device. The water passing through the filter device is discharged from the drain holes beside the impeller.

[0003] At present, many pool sewage suction devices on the market mostly suck the garbage and pollutants on the water surface into the interior through suction force, but this method can only achieve preliminary cleaning. For smaller impurities and other pollutants, a single sewage suction device often cannot efficiently filter, resulting in that the water quality cannot be thoroughly cleaned. In addition, the existing equipment also generally has problems of limited volume, insufficient space and the like in garbage storage, which requires frequent discharge of garbage, increasing maintenance cost and operation complexity.
