Abstract: A water cleaner, including a housing and a filter mechanism. Two ends of the housing are provided with a first inlet and a first outlet, respectively. The filter mechanism is arranged in the housing. A first end and/or an outer circumference of the filter mechanism are/is provided with a second inlet, and a second end is provided with a second outlet. The sewage flows into the housing through the first inlet and flows towards the filter mechanism to be filtered. The obtained clean water flows into the filter mechanism through the second inlet and flows out of the housing through the second outlet and the first outlet in sequence. The first end of the filter mechanism is close to the first inlet, and the second end is close to the first outlet.
Abstract: An electric pool-cleaning robot, including a housing, a first filtering mechanism and a rotating wheel. One end of the housing is provided with a first water inlet, and the other end of the housing is provided with a first water outlet. The first filtering mechanism is arranged in the housing. The water enters the housing through the first water inlet, and then flows toward the first filtering mechanism to be filtered. The filtered water flows out of the housing through the first water outlet. The rotating wheel is arranged on the housing, and is capable of rotating to drive the housing to move.
Abstract: The invention relates to electric robots, and more particularly to a electric robot for pool cleaning, including a base with a water inlet channel, a volute assembly and a motor assembly capable of outputting positive and negative torques; where the volute assembly is rotatably provided above the base and communicates with the water inlet channel; the volute assembly includes a casing and an impeller assembly provided therein; a water outlet is provided on a side of the casing, and an water outlet channel is provided inside the casing to allow water to flow through the impeller assembly; the motor assembly is provided on the base, and connected with the impeller assembly through an output shaft; and an upper end surface of the base is provided with a limit structure for limiting a rotation angle of the volute assembly.
