Description

Technical Field

[0001] The utility model relates to the field of pool cleaners, in particular to a pool cleaner and a one-way driving structure of a wheel brush thereof. 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. The pool cleaner is equipped with a wheel brush for cleaning the bottom of the pool. The suction port of the pool cleaner is adjacent to the wheel brush, and the wheel brush can move the dirt to the suction port.

[0003] The existing wheel brush will switch forward and reverse accordingly when the pool cleaner moves forward and backward. In this way, there will be a period of time (such as the period when the pool cleaner moves forward or backward) when the rotation of the wheel brush pushes the dirt away from the suction port, affecting the suction port's absorption of the dirt and affecting the cleaning effect of the pool.

[0004] In view of the above problems, it is necessary to study a pool cleaner and a one-way drive structure for a wheel brush thereof, which can enable the wheel brush to always rotate in a fixed direction when the pool cleaner moves. Utility Model Content

[0005] The utility model aims to provide a pool cleaner and a one-way driving structure of a wheel brush thereof, which can make the wheel brush always keep rotating in a fixed direction when the pool cleaner moves.

[0006] In order to achieve the above purpose, the solution of the utility model is:

[0007] A one-way drive structure for a wheel brush of a pool cleaner, comprising a one-way driver and a wheel brush; the one-way driver comprises a driving member rotatably mounted on a cleaner body of the pool cleaner, a first driving wheel, a second driving wheel, a driven wheel and a reversing wheel; the driving member is respectively in unidirectional transmission cooperation with the first driving wheel and the second driving wheel, and the unidirectional rotation directions of the first driving wheel and the second driving wheel are opposite; the first driving wheel is meshed with the driven wheel, the second driving wheel is in transmission cooperation with the driven wheel through the reversing wheel, and the reversing wheel is respectively meshed with the second driving wheel and the driven wheel; the wheel brush is in transmission cooperation with the driven wheel, and the wheel brush and the driven wheel rotate synchronously.

[0008] A circle of first one-way ratchet teeth is formed inside the first driving wheel; the driving member is matched with a first one-way meshing member, and the first one-way meshing member is provided with at least two first one-way pawls that are one-way meshed with the first one-way ratchet teeth.

[0009] The driving member is coaxially connected to the first one-way engaging member.

[0010] A circle of second one-way ratchet teeth is formed inside the second driving wheel; the driving member is matched with a second one-way meshing member, and the second one-way meshing member is provided with at least two second one-way pawls that are one-way meshed with the second one-way ratchet teeth.

[0011] The driving member is coaxially connected to the second one-way engagement member.

[0012] The driven wheel has a first gear portion and a second gear portion which are coaxially arranged, the first gear portion is meshed with the first driving wheel, and the second gear portion is meshed with the reversing wheel.

[0013] The second gear portion has a smaller diameter than the first gear portion.

[0014] The wheel brush is coaxially connected with the driven wheel.

[0015] A pool cleaner has at least one wheel brush one-way driving structure as described above.

[0016] The pool cleaner has two wheel brush one-way driving structures, and the wheel brushes of the two wheel brush one-way driving structures are respectively located on two opposite sides of the cleaning body of the pool cleaner.

[0017] The pool cleaner has two travel motors, and the two travel motors respectively drive the driving members of the two wheel brush one-way driving structures to rotate.

[0018] The pool cleaner has two sewage suction ports, and the two sewage suction ports are respectively arranged adjacent to the wheel brushes of the two wheel brush one-way driving structures.

[0019] The bristles of the wheel brushes of the two wheel brush one-way driving structures respectively move against the edges of the two sewage suction ports.

[0020] After adopting the above scheme, when the driving member rotates forward, the driving member drives the first active wheel to rotate forward and the driving member does not drive the second active wheel to rotate, and then the first active wheel drives the driven wheel to rotate forward, so that the driven wheel drives the wheel brush to rotate forward; and when the driving member rotates reversely, the driving member drives the first active wheel to rotate and the driving member drives the second active wheel to rotate reversely, and then the second active wheel drives the driven wheel to rotate forward through the reversing wheel, so that the driven wheel still drives the wheel brush to rotate forward; from the foregoing, it can be seen that the one-way driving structure of the wheel brush of the utility model can make the wheel brush always keep rotating in one direction, so that the utility model can control the wheel brush to rotate in the direction of pushing the dirt to the sewage suction port, thereby improving the cleaning effect.

[0039] In the present invention, when the driving member 11 rotates forward, the driving member 11 drives the first driving wheel 12 to rotate forward and the driving member 11 does not drive the second driving wheel 13 to rotate, and then the first driving wheel 12 drives the driven wheel 14 to rotate forward, so that the driven wheel 14 drives the wheel brush 2 to rotate forward; and when the driving member 11 rotates reversely, the driving member 11 drives the first driving wheel 12 to rotate and the driving member 11 drives the second driving wheel 13 to rotate reversely, and then the second driving wheel 13 drives the driven wheel 14 to rotate forward through the reversing wheel 15, so that the driven wheel 14 still drives the wheel brush 2 to rotate forward; from the foregoing, it can be seen that the wheel brush unidirectional drive structure of the present invention can make the wheel brush 2 always rotate in one direction.

[0040] In an embodiment of the utility model, the pool cleaner has two wheel brush one-way drive structures, and the wheel brushes 2 of the two wheel brush one-way drive structures are respectively located on opposite sides of the cleaner body 4 of the pool cleaner, so that the cleaning efficiency of the pool can be improved. Among them, the pool cleaner has two travel motors 3, and the two travel motors 3 respectively drive the driving members 11 of the two wheel brush one-way drive structures to rotate; the two travel motors 3 can be respectively driven and matched with the driving members 11 of the two wheel brush one-way drive structures through the gear transmission mechanism 5; the pool cleaner has two sewage suction ports 41, and the two sewage suction ports 41 are respectively arranged adjacent to the wheel brushes 2 of the two wheel brush one-way drive structures, so as to improve the collection efficiency of dirt, and the bristles 21 of the wheel brushes 2 of the two wheel brush one-way drive structures respectively move against the edges of the two sewage suction ports 41 to effectively remove the dirt attached to the bristles 21 of the wheel brush 2.

[0041] In an embodiment of the utility model, a circle of first one-way ratchet teeth 121 is formed on the inner side of the first driving wheel 12, and a circle of second one-way ratchet teeth 131 is formed on the inner side of the second driving wheel 13; the driving member 11 is equipped with a first one-way meshing member 16 and a second one-way meshing member 17, and the first one-way meshing member 16 and the second one-way meshing member 17 are coaxially connected to the driving member 11, and the first one-way meshing member 16 is provided with at least two first one-way pawls 161 that are unidirectionally meshed with the first one-way ratchet teeth 121, so that the driving member 11 and the first driving wheel 12 are unidirectionally transmitted, and the second one-way meshing member 17 is provided with at least two second one-way pawls 171 that are unidirectionally meshed with the second one-way ratchet teeth 131, so that the driving member 11 and the second driving wheel 13 are unidirectionally transmitted.
