[0003] The present disclosure relates to a water tank cleaner, in particular to an electric cleaner including, among other things, a filter box.BACKGROUND:

[0004] Due to the accumulation of dirt at the bottom of the pool after long-term use, it is necessary to regularly clean the pool. At present, many people use poolcleaners that can swim 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 works, the water in the pool flows sequentially through the pool cleaner and the water pump before returning to the pool. The water flowing through the pool cleaner drives the impeller of the pool cleaner to rotate and drive it to move. However, the setting of water pipes can greatly interfere with the movement of the pool cleaner, thereby affecting the cleaning effect of the pool cleaner.

[0005] Existing pool cleaners, when in use, will allow the water flow mixed with dirt to flow through the trash box (hereinafter, “the filter box” or “the box body”), and the filter box will filter the water flow. The dirt in the water flow will be left in the filter box. The filter box is generally detachably connected to the body of the pool cleaner, so that the filter box can be removed separately for cleaning the dirt in the filter box. After the existing filter box is removed, it is generally first used to pour out the water flow in the filter box from the clear water outlet of the filter box, thereby reducing the weight of the filter box for easy movement of the filter box. However, at present, the speed of pouring out the water flow from the clear water outlet of the filter box may be too slow.

[0006] Given the existence of the aforementioned issues, it is desirable to provide an electric cleaner that has the advantage of flexible walking and a filter box which can quickly discharge the water flow.SUMMARY:

[0084] To further explain the technical solution of the present disclosure, the following will provide a detailed explanation of the present disclosure through specific embodiments. As shown in FIGS. 1-30, the present disclosure discloses an electric cleaner, comprising a cleaner body A and a driving control device B, a filtering device C, and a cleaning device D installed on the cleaner body A. The left and right sides of the cleaner body A are respectively equipped with left walking devices E and right walking devices F. The driving control device B has two walking motors 1 , a main control board 2 electrically connected to the two walking motors 1 , and a power supply battery 3 electrically connected to the main control board 2. The walking output shafts 11 of the two walking motors 1 are respectively matched with the left walking device E and the right walking device F for transmission. The cleaning device D is used to clean the dirt attached to the bottom and wall of the pool, and the filtering device C is used to filter the water flow to collect dirt in the water flow.

[0085] The electric water tank cleaner of the present disclosure drives the left walking device E and the right walking device F, respectively, through two walking motors 1 , and the walking motors 1 are directly powered by the power supply battery 3. The electric water tank cleaner of the present disclosure does not need to be connected to an external water pump through a water pipe, nor does it need to be connected to an external power source through a cable. Therefore, the electric water tank cleaner of thepresent disclosure will not be disturbed by water pipes and cables during walking, making it have the advantage of flexible walking.

[0086] In an embodiment of the present disclosure, the cleaning device D comprises at least one rotatable wheel brush D1 installed on the cleaning device body A. Specifically, the number of wheel brushes D1 in the cleaning device D is two, and the two wheel brushes D1 can be rotatably installed at the front and rear of the cleaner body A. The wheel brushes D1 can clean the dirt attached to the bottom and wall of the pool.

[0087] In embodiments of the present disclosure, each wheel brush D1 is driven and matched with a walking motor 1 of the driving control device B through a unidirectional driving mechanism G. The filtering device C has a suction port C103 adjacent to the wheel brush D1 , and the water of the water tank enters the filtering device C from the suction port C103. Each wheel brush D1 of the present disclosure is driven and matched with a walking motor 1 of the driving control device B through a unidirectional driving mechanism G, which can keep the wheel brush D1 rotating in the same direction, so that the present disclosure can control the wheel brush D1 to rotate continuously in the direction of pushing dirt towards the suction port C103, which may improve the efficiency of filtering device C to collect dirt, and effectively improve the cleaning effect of the water tank. The bristles D11 of the wheel brush D1 move against the edge of the suction port C103 adjacent to the wheel brush D1 , which can remove the dirt attached to the bristles D11 of the wheel brush D1 .

[0088] In an embodiment of the present disclosure, the unidirectional driving mechanism G comprises a rotatable drive component G1 installed on the cleaner body A, a first driving wheel G2, a second driving wheel G3, a driven wheel G4, and a reversing wheel G5. Drive component G1 is in transmission coordination with walking motor 1 , driven wheel G4 is in transmission coordination with wheel brush D1 , and the cleaning brush rotates synchronously with driven wheel G4 (driven wheel G4 and wheel brush D1 can be inserted and matched). Drive component G1 is in one-way transmission coordination with the first driving wheel G2 and the second driving wheel G3, and the one-way rotation directions of the first driving wheel G2 and the second driving wheel G3 are opposite. The first driving wheel G2 is engaged with the drivenwheel G4, and the second driving wheel G3 is in transmission coordination with the driven wheel G4 through the reversing wheel G5. The reversing wheel G5 is engaged with the second driving wheel G3 and the driven wheel G4 respectively. When the walking motor 1 drives the drive component G1 to rotate in the forward direction, the drive component G1 drives the first driving wheel G2 to rotate in the forward direction, and the drive component G1 does not drive the second driving wheel G3 to rotate. Then, the first driving wheel G2 drives the driven wheel G4 to rotate in the forward direction, causing the driven wheel G4 to drive the wheel brush D1 to rotate in the forward direction. When the walking motor 1 drives the drive component G1 to rotate in the opposite direction, the drive component G1 drives the first driving wheel G2 to rotate, and the drive component G1 drives the second driving wheel G3 to rotate in the opposite direction. Then, the second driving wheel G3 drives the driven wheel G4 to rotate in the forward direction through the reversing wheel G5, so that the driven wheel G4 still drives the wheel brush D1 to rotate in the forward direction. As mentioned above, the unidirectional driving mechanism G can keep the wheel brush D1 rotating in one direction at all times. A first unidirectional ratchet G21 is formed on the inner side of the first driving wheel G2, and a second unidirectional ratchet G31 is formed on the inner side of the second driving wheel G3. The drive component G1 is matched with a first unidirectional meshing component G6 and a second unidirectional meshing component G7. The first unidirectional meshing component G6 is equipped with at least two first unidirectional pawls G61 that are unidirectionally engaged with the first unidirectional ratchet G21 , which enables the drive component G1 to be unidirectionally matched with the first driving wheel G2. The second unidirectional meshing component G7 is equipped with at least two second unidirectional pawls G71 that are unidirectionally engaged with the second unidirectional ratchet G31 , which enables the drive component G1 to be unidirectionally matched with the second driving wheel G3. The driven wheel G4 has a first gear portion G41 and a second gear portion G42 coaxially arranged. The first gear portion G41 is engaged with the first driving wheel G2, and the second gear portion G42 is engaged with the reversing wheel G5. This arrangement facilitates the setting of the reversing wheel G5. At the same time, the present disclosure can also control the transmission ratio between the first driving wheelG2 and the driven wheel G4, as well as the transmission ratio between the reversing wheel G5 and the driven wheel G4, so that the rotational speed of the wheel brush D1 is less than that of the wheel brush D1 when the direction of rotation of the wheel brush D1 hinders the movement of the electric water tank cleaner of the present disclosure. The rotational speed during obstruction may reduce the obstruction effect of the wheel brush D1 on the movement of the electric water tank cleaner of the present disclosure.

[0089] In an embodiment of the present disclosure, the two wheel brushes D1 of the cleaning device D are respectively driven and matched with the left walking device E and the right walking device F through two unidirectional driving mechanisms G, so that the two walking motors 1 can drive the two wheel brushes D1 to rotate separately. Specifically, the drive component G1 of one of the two one-way driving mechanisms G is matched with one of the left walking device E and the right walking device F, and the drive component G1 of the other one-way driving mechanism G is matched with the other drive component G1 of the left walking device E and the right walking device F. This arrangement helps to make the electric water tank cleaner of the present disclosure walk more smoothly.
