Description

TECHNICAL FIELD

[0001] The present utility model relates to the technical field of swimming pool cleaning devices, in particular a pool dirt vacuum cleaner. STATE OF THE ART

[0002] State-of-the-art water tank dirt extractors operate using a pump-like mechanism: the rotation of the electric motor causes the impeller to rotate at high speed. Under the influence of the centrifugal force generated by the impeller's high-speed rotation, the water flow in the flow channel of the dirt extraction chamber is propelled outward toward the outlet openings on the periphery of the impeller. This creates a vacuum in the impeller area, and under the influence of the pressure difference, the water from the tank is sucked back into the dirt extraction chamber, simultaneously sucking in contaminants such as sand and leaves in the water tank.The core of the water basin dirt extractor consists of a dirt extraction chamber, a motor chamber, and an impeller arranged at the top and bottom. The dirt extraction chamber is located at one end portion of the product, and the impeller is located between the dirt extraction chamber and the motor chamber. The impeller is connected to the output shaft of the electric motor. A filter device is arranged in the dirt extraction chamber, which is located at the front end of the dirt extraction chamber. The motor chamber consists of an electric motor, wires, and switches, etc. The impeller is provided with some drainage holes on the periphery.When working, water and dirt come out from the opening position of the dirt suction chamber and pass through the filter device of the dirt suction chamber, then dirt adheres in the filter device, and the passing water is discharged from the drainage holes next to the impeller.

[0003] Many existing pool debris vacuums on the market usually use suction to suck waste and debris on the water surface into the pool, but this method can only achieve initial cleaning. For finer debris and other contaminants, a single vacuum unit is often unable to filter them efficiently, resulting in incomplete water purification. In addition, existing units typically have limited volume and insufficient space for waste storage, requiring frequent disposal, increasing maintenance costs and operational complexity.
