Description

Technical Field

[0001] The utility model relates to a pool cleaner, in particular to an electric pool cleaner. Background Art

[0002] Since dirt will accumulate on the bottom of the pool after long-term use, the pool needs to be cleaned regularly. At present, many people use a pool cleaner that can move in the pool to clean the pool; many existing pool cleaners are driven by hydraulic power. Specifically, the pool cleaner is connected to an external water pump through a water pipe. When the water pump is working, the water in the pool flows through the pool cleaner and the water pump in turn and then flows back to the pool. The water flowing through the pool cleaner will drive the impeller of the pool cleaner to rotate and drive the pool cleaner to move; however, the setting of the water pipe will greatly interfere with the movement of the pool cleaner, thereby affecting the cleaning effect of the pool.

[0089] The electric pool cleaner of the utility model uses two travel motors 1 to drive the left travel device E and the right travel device F respectively, and the travel motor 1 is directly powered by the power supply battery 3; when the electric pool cleaner of the utility model is in use, there is no need to connect an external water pump through a water pipe, and there is no need to connect an external power supply through a cable, so that the electric pool cleaner of the utility model will not be interfered by the water pipe and the cable when moving, so that the electric pool cleaner of the utility model has the advantage of flexible walking.

[0090] In an embodiment of the utility model, the cleaning device D includes at least one wheel brush D1 rotatably mounted on the cleaner body A; specifically, the number of the wheel brushes D1 of the cleaning device D is two, and the two wheel brushes D1 are rotatably mounted on the front and rear parts of the cleaner body A, respectively, and the wheel brush D1 can clean the dirt attached to the bottom and wall of the pool.

[0091] In an embodiment of the utility model, each wheel brush D1 is driven and matched with a travel motor 1 of a drive control device B through a one-way drive mechanism G; the filter device C has a sewage suction port C103 adjacent to the wheel brush D1, and the water of the pool enters the filter device C from the sewage suction port C103; wherein, each wheel brush D1 of the utility model is driven and matched with a travel motor 1 of a drive control device B through a one-way drive mechanism G, so that the wheel brush D1 can always rotate in the same direction, so that the utility model can control the wheel brush D1 to rotate in the direction of pushing the dirt to the sewage suction port C103, thereby improving the efficiency of the filter device C in collecting dirt, thereby effectively improving the cleaning effect of the pool. The bristles D11 of the wheel brush D1 are movable to contact the edge of the sewage suction port C103 adjacent to the wheel brush D1, so that the dirt attached to the bristles D11 of the wheel brush D1 can be removed.

[0092] In an embodiment of the utility model, the unidirectional driving mechanism G comprises a driving member G1, a first driving wheel G2, a second driving wheel G3, a driven wheel G4 and a reversing wheel G5 rotatably mounted on the cleaning device body A; the driving member G1 is in transmission cooperation with the travel motor 1, the driven wheel G4 is in transmission cooperation with the wheel brush D1, and the cleaning brush rotates synchronously with the driven wheel G4 (the driven wheel G4 and the wheel brush D1 can be plugged in and matched), the driving member G1 is in unidirectional transmission cooperation with the first driving wheel G2 and the second driving wheel G3 respectively, and the unidirectional rotation directions of the first driving wheel G2 and the second driving wheel G3 are opposite, the first driving wheel G2 is meshed with the driven wheel G4, the second driving wheel G3 is in transmission cooperation with the driven wheel G4 through the reversing wheel G5, and the reversing wheel G5 is in transmission cooperation with the second driving wheel G3 and The driven wheels G4 are meshed respectively; when the travel motor 1 drives the driving member G1 to rotate forward, the driving member G1 drives the first driving wheel G2 to rotate forward and the driving member G1 does not drive the second driving wheel G3 to rotate, and then the first driving wheel G2 drives the driven wheel G4 to rotate forward, so that the driven wheel G4 drives the wheel brush D1 to rotate forward; and when the travel motor 1 drives the driving member G1 to rotate reversely, the driving member G1 drives the first driving wheel G2 to rotate and the driving member G1 drives the second driving wheel G3 to rotate reversely, and then the second driving wheel G3 drives the driven wheel G4 to rotate forward through the reversing wheel G5, so that the driven wheel G4 still drives the wheel brush D1 to rotate forward; from the foregoing, it can be seen that the unidirectional drive mechanism G can make the wheel brush D1 always rotate in one direction.
