The battery pack can be any battery with charging and power storage functions, the control mainboard operates and controls the supercharging device through a control key arranged on the shell and connected with the control mainboard, and the control mainboard can be a simple PCB circuit board and can realize the functions of controlling the starting of the supercharging device and adjusting the supercharging amplitude.

As shown in fig. 1, the litter box assembly also includes a base 13 located below the litter box 12 and a housing 11 covering the litter box. As shown in fig. 4, the spray arm 2 is connected to the housing 11 by a connecting assembly 22. As shown in fig. 5, the connection assembly 22 includes a claw 222 fixedly arranged on the spray arm and a connection column 221 fixedly arranged in the housing and clamped into the claw, and the spray arm 2 is positioned right above the litter box 12 and can rotate around the connection column 221. Base 13 is used for supporting cat litter basin 12 and plays the effect of addding other subassemblies, and the setting up of shell 11 is fixed supercharging device and water storage device on the one hand covers the outside that makes the nozzle spun water can not splash the cat litter basin with cat litter basin on the other hand.

As shown in fig. 4 and 6, the claw 222 is located at the middle of the length direction of the spray arm, the nozzle 21 is arranged at the bottom of the spray arm 2, the nozzle 21 is inclined at an angle with the vertical direction of the cat litter box 12, and the inclination angles of the nozzles 21 at the left side and the right side of the spray arm 2 are different. In addition, the number of the nozzles 21 on the left and right sides of the spray arm 2 may be different or the inclination angle and the number of the nozzles 21 on the left and right sides of the spray arm 2 may be different, so that the difference of the water column reaction force is generated when the water is sprayed on the left and right sides of the spray arm. Simultaneously spray arm 2's length is less than the diameter of cat litter basin 12, further avoids spraying rivers to cat litter basin 12 outside, because nozzle 21 is inclination, inside the spun rivers are the type of dispersing from the nozzle and spray the cat litter basin, can cover each region in the cat litter basin comprehensively.

The design of the nozzle 21 and attachment assembly 22 enables the spray arm 2 to be rotated circumferentially about the attachment post 221 when spraying water to repeatedly wash the litter box 12. Specifically, the connection column 221 is hollow and cylindrical, a hollow cylindrical structure is arranged in the claw 222 as a water inlet, the water inlet is inserted into the connection column 221 during assembly, the hose 33 is connected to the other end of the connection column 221 on the shell 11, a connection channel (not shown in the figure) is further arranged inside the spray arm, the connection channel connects the water inlet on the spray arm 2 with each nozzle 21, and water flow can reach each nozzle 21 after entering the spray arm 2 and is sprayed out from each nozzle 21 at a high speed. As shown in fig. 5, a connecting disc 223 with a diameter larger than that of the connecting column 221 is provided at the bottom of the connecting column 221, and the claw head of the claw 222 is pressed on the connecting disc 223 to connect the spray arm 2 with the housing 11. Meanwhile, a gap is formed between the jaw head and the connecting disc, when water flows through the nozzles to the outside spraying position, because the quantity and/or the water outlet direction of the nozzles on the left side and the right side of the spray arm are/is asymmetric, the counter-acting force generated when the nozzles on the two sides spray water is poor, and the spray arm is pushed to rotate around the circumference of the connecting column under the counter-acting force difference.
