Principle of operation

When the time set outside is up or after manual start, the lifting motor 30 arranged in the shell 10 is started, the rotating shaft 31 is rotated, the rotating shaft 31 rotates to drive the basin bottom reel 33 at the tail end to rotate, and the basin wall reel 32 meshed with the basin bottom reel 33 rotates at the same time;

the pull rope 34 wound on the surface is pulled due to the rotation of the basin bottom reel 33, the sliding shell 37 is lifted due to the winding of the pull rope 34, meanwhile, the basin wall reel 32 pulls up the basin wall spool 29 through the pull rope due to the rotation of the basin bottom reel 33 and the basin wall spool 29 is lifted faster due to the larger basin wall reel 32;

in the process of lifting the sliding shell 37, as the ratchet bar 35 in the sliding groove 36 is meshed with the big ratchet gear 40, the big ratchet gear 40 rotates, as the big ratchet gear 40 rotates to enable the transmission pinion 46 fixedly arranged on the surface to rotate, as the transmission pinion 46 rotates to drive the driven pinion 45 meshed with the big ratchet gear 46 to rotate, as the driven pinion 45 rotates to enable the stirring gear shaft 44 to rotate and drive the intermittent gear 43 and the stirring gear 42 on the surface of the stirring gear shaft 44 to rotate, after the stirring gear 42 and the intermittent gear 43 rotate by a certain angle, the stirring gear 42 is contacted with the rotating post 58 arranged between the stirring gear 42 and the intermittent gear 43 and pushes the rotating post 58 towards one side of the basin bottom 21, at the moment, the transmission bevel gear 50 is meshed with the driven bevel gear 39, and when the continuous rotation is continued, the stirring gear 42 pushes the rotating post 58 upwards, so that the meshing pinion 51 is meshed with the intermittent gear 43 and drives the meshing pinion 51 to rotate, and therefore, the driven bevel gear 50 also rotates to enable the basin bottom transmission shaft 38 to rotate to turn over the basin bottom 21, when the sliding shell 37 continues to lift up, the stirring gear 42 rotates by a certain angle, the rotating post 58 is not acted on the rotating post 58 and is further pulled out of the rotating post 48, and the rotating post 52 is meshed with the rotating post 52, and the rotating post is completed;

after the basin bottom 21 is turned over, the lifting motor 30 stops rotating, the sliding shell 37 descends under the action of gravity, the basin bottom 21 cannot be turned over because the surfaces of the ratchet gear 40 and the ratchet bar 35 are ratchet teeth, the basin bottom reel 33 reversely rotates to drive the basin wall reel 32 to reversely rotate because the sliding shell 37 descends to pull the pull rope 34, the basin wall 14 gradually descends and closes with the basin bottom 21 below through the inserting column 22 after the pull force of the basin wall sliding column 29 is lost, and then the motor in the cat litter box 18 discharges new cat litter into the cat litter basin through the discharging hose 53;

the cleaning hydraulic pump 57 is then started, air is injected or pumped into the cleaning rod 23 so that the supporting end 54 can reciprocate, the supporting column 55 is pushed upwards through the air passage so that the cleaning cotton 26 contacts the lower surface of the basin bottom 21 for wiping, and meanwhile, water in the water storage tank 17 is injected into the supporting column 55 through the water delivery hose 24 and gradually seeps out of the surface of the cleaning cotton 26 through the penetrating holes 27 to achieve a further cleaning effect.

The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes using the descriptions and the drawings of the present invention or directly or indirectly applied to other related technical fields are included in the scope of the invention.
