The driving control device E is respectively in transmission cooperation with the first walking device F, the second walking device G and the water spraying device C.

[0047] When the pool cleaner of the present invention is in use, the driving control device E drives the first walking device F and the second walking device G to act to drive the entire pool cleaner to walk in the pool; during the walking in the pool, the cleaning device D brushes the dirt attached to the pool bottom S1 and the pool wall S2, and the driving control device E drives the water spraying device C to work, so that the water in the pool flows through the filtering device B and the water spraying device C in sequence and then sprays out from the spray pipe H, and the filtering device B will collect the dirt in the water flow. In this way, the pool cleaner of the present invention can realize the brushing and collection of the dirt in the pool, so as to clean the pool. Among them, cooperate Figure 4As shown in the figure, when the pool cleaner of the present invention walks upward on the pool wall S2, since the outlet of the spray pipe H is inclined to the walking direction of the pool cleaner, the water flow ejected from the spray pipe H at this time will form an angle with the pool wall S2, so that the water flow ejected from the spray pipe H will exert two reaction forces on the pool cleaner. One reaction force F1 drives the pool cleaner to lean against the pool wall S2, and the other reaction force F2 will drive the pool cleaner to walk upward along the pool wall S2. In this way, the pool cleaner of the present invention can walk steadily upward on the pool wall S2 of the pool, thereby improving the cleaning effect on the pool wall S2.

[0048] In an embodiment of the present invention, the cleaner body A is assembled by a plurality of components, which facilitates the installation of the filtering device B, the water spraying device C, the cleaning device D and the drive control device E. The cleaner body A may be provided with a pick-up and placement opening A1 corresponding to the filtering device B for picking up and placing the filtering device B, and the filtering device B is inserted into the cleaner body A, so that the filtering device B is convenient to disassemble and assemble; and the cleaner body A is provided with a pick-up and placement cover I for actively opening and closing the pick-up and placement opening A1 and a locking assembly J for locking the pick-up and placement cover I; when installing the filtering device B, first open the pick-up and placement cover I, then load the filtering device B into the cleaner body A from the pick-up and placement opening A1, and then close the pick-up and placement cover I and make the locking assembly J lock the pick-up and placement cover I to prevent the filtering device B from falling out; when disassembling the filtering device B, first make the locking assembly J release the lock on the pick-up and placement cover I, then open the pick-up and placement cover I, then take out the filtering device B from the pick-up and placement opening A1, and then close the pick-up and placement cover I.

The locking assembly J may include a locking seat J1 and a locking torsion spring J2. The locking seat J1 is rotatably fitted to the cleaner body A, and the locking torsion spring J2 is fitted between the locking seat J1 and the cleaner body A. The locking torsion spring J2 is used to drive the locking seat J1 to abut against the inner wall of the other side of the pick-up and placement cover I. The locking seat J1 has a pressing portion J11 located outside the cleaner body A. The user can unlock and open the pick-up and placement cover I with one hand. Specifically, the user first presses the pressing portion J11 of the locking seat J1 with one hand to drive the locking seat J1 to rotate, so that the locking seat J1 releases the abutment against the pick-up and placement cover I to unlock the pick-up and placement cover I. At this time, the user's hand can just hook the side of the pick-up and placement cover I for cooperating with the locking seat J1. After that, the user's hand directly drives the pick-up and placement cover I to rotate to fully open the pick-up and placement cover I, and this operation is very convenient.

[0050] In an embodiment of the present invention, the cleaner body A may be provided with a drain port A2 communicating with the clean water port B02 of the filtering device B. The drain port A2 can be communicated with the clean water port B02 of the filtering device B through the inner cavity of the cleaner body A. When the user wants to take out the pool cleaner of the present invention from the pool, the water flow inside the pool cleaner can be discharged through the drain port A2, reducing the overall weight, thereby facilitating the user to take out the pool cleaner from the pool. A handle A4 may be provided on one side of the cleaner body A, and the drain port A2 is arranged away from the handle A4. When the user holds the handle A4 to take out the pool cleaner of the present invention from the pool, since the drain port A2 is arranged away from the handle A4, the water flow inside the pool cleaner at this time will be discharged along the drain port A2, making the whole operation of the user very smooth and convenient.

The sewage suction port B01 is provided with a sewage suction check valve piece B3 for controlling the unidirectional inflow of water into the sewage cavity B031. When the spraying device C works, the spraying device C can control the water flow to flow through the sewage suction port B01, the sewage cavity B031, the filter element B2, the clean water cavity B032 and the clean water port B02 in sequence. The filter element B2 can intercept the dirt in the water flow in the sewage cavity B031; when the water pump stops working, the sewage suction check valve piece B3 closes the sewage suction port B01, thereby preventing the dirt in the sewage cavity B031 from flowing out through the sewage suction port B01. Among them, the filter box B1 can be disassembled to facilitate the cleaning of the dirt on the sewage cavity B031 and the filter element B2; the sewage suction check valve piece B3 can be of an elastic structure. The sewage suction check valve piece B3 is fitted inside the sewage cavity B031 and one side of the sewage suction check valve piece B3 is connected to the filter box B1.
