[0002] The cat litter boxes provided in the prior art are generally push-type cat litter boxes and drum-type cat litter boxes.

[0003] Push-type cat litter boxes are the mainstream product of open cat litter boxes at present, but their claws cannot scoop to the bottom of the litter box. Therefore, the feces balls are not very clean. In many cases, the feces balls will be broken. After cat urine enters the cat litter box, it may flow to the bottom of the box and then be absorbed by the cat litter, and then adsorbed to the bottom of the box and agglomerated. In this case, the push-type structure is completely unable to solve it.

[0004] The drum-type cat litter box, on the other hand, filters out the cat litter and cat feces or cat urine by rotating the cat litter barrel; during the rotation process, the cat litter is also turned over, which will produce a strong smell, and the cat feces will roll with it, and may be damaged or stick to other places. As for cat urine, if it is adsorbed to the bottom, it cannot be separated by gravity when rolling. Utility Model Content

[0026] In order to better understand the technical solution of the present utility model, the embodiments provided by the present utility model are described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-2 As shown, it can be understood that a cat litter box provided in this embodiment includes: a shell, a litter box 2 is provided in the shell 1, and a shovel 4 is provided above the litter box 2; a slide rail 3 is also provided on the shell 1, and a carriage can slide on the slide rail 3, and the shovel 4 is rotatably connected to the carriage 5; the slide rail 3 and the bottom of the litter box 2 are both arc-shaped, and the curvature is the same and the position corresponds; the tip 43 of the blade is wing-shaped, and a protrusion 431 is provided on the tip.

[0028] In this embodiment, the litter box 2 is used to hold cat litter, and the shovel blade 4 is used to scoop out cat feces after the cat urinates and defecates; the special feature is that a slide rail 3 is provided on the housing 1 to guide the sliding of the trolley 5, and the sliding of the trolley 5 drives the shovel blade 4 connected thereto to move, thereby realizing the cleaning of cat feces. In this embodiment, the bottom of the litter box 2 is designed to be an arc shape that is convenient for the shovel blade 4 to fit, so that when the shovel blade 4 is working, the shovel blade 4 can fit the bottom of the litter box 2 throughout the entire process; in order to make the shovel blade 4 fit completely to the bottom of the cat litter box, the slide rail 3 that drives the trolley 5 to move is also designed to be a corresponding arc shape, so that the shoveling angle of the shovel blade 4 is exactly the same when shoveling, and the shovel blade 4 fits completely.

[0029] In addition, if Figure 1 As shown, the blade tip 43 is an airfoil structure (i.e., it has a certain raised portion 431 at the top). When working, the blade tip 43 is responsible for shoveling cat feces from the bottom, and then the shovel blade 4 moves back and forth. At this time, the cat feces will float to the surface of the cat litter, and then move forward. The cat feces will stay on the top of the raised portion 431, and the cat feces will not accumulate in front of the blade tip 43 that contacts the bottom for a long time. The raised portion 431 is higher, so during the pushing process, the cat feces will be higher than the cat litter and will not be pushed away. On the contrary, if there is no airfoil blade tip 43, the cat feces will be concentrated in front of the blade tip 43, and the excess cat litter will also be pushed away.

[0030] Furthermore, the ends of the blade tips 43 are provided with auxiliary sections 432 in the transverse direction, and the auxiliary sections 432 are arranged at an angle to the direction of travel of the shovel blade 4. The blade tips 43 of the shovel blade 4 in the prior art are usually arranged in a straight line or a downward arc shape, without any turning at the tip. This design will result in a certain gap between adjacent blade tips. When shoveling cat feces, the cat feces in the gap are not easy to scoop up and are easy to leak; while in this embodiment, a transverse auxiliary section 432 is arranged at the end of the blade tip 43, and the auxiliary section 432 is usually arranged perpendicular to the blade tip 43, and can also be arranged at other angles, so that when shoveling cat feces, the cat feces can be pushed and scooped up as much as possible.

[0031] In this embodiment, if Figure 3As shown, the sand basin 2 is detachably connected to the shell 1. The sand basin 2 can be conveniently disassembled for cleaning. Specifically, a mounting groove 11 is provided in the shell, and the top of the sand basin 2 is detachably arranged on the mounting groove 11. A circle of mounting grooves 11 is provided in the shell 1 along the top of the sand basin 2. The mounting groove 11 can be a groove chiseled in the shell 1, or it can be protruded outwardly, and the top of the sand basin 2 can be placed. The top of the sand basin 2 protrudes slightly outward, which is convenient for being placed on the mounting groove 11, forming a drawer-type detachable sand basin 2.

[0032] Furthermore, a toilet bowl 6 is provided at one end of the sand basin 2, and the shovel 4 can slide back and forth toward the toilet bowl 6 through the slide rail 3; a rotatably connected toilet bowl cover 7 is provided on the toilet bowl 6, and the opening direction and connection direction of the toilet bowl cover 7 and the toilet bowl 6 are opposite.

[0033] The toilet 6 is provided with a rotatably connected toilet cover 7, and the opening direction and connection direction of the toilet cover 7 and the toilet 6 are opposite. The toilet cover 7 can be used to close the toilet 6 to prevent odor from overflowing. The toilet cover 7 is rotatably connected to the toilet 6, and its opening is opposite to the connection, which is convenient for opening.

[0034] In addition, the opening of the toilet bucket 6 is connected to the litter box 2, and the shovel blade 4 faces the opening direction of the toilet bucket 6, and the end of the shovel blade 4 fits with the litter box 2. The opening between the toilet bucket cover 7 and the toilet bucket 6 is connected to the litter box 2, which facilitates the shovel blade 4 to directly shovel cat feces from the litter box 2 into the toilet bucket 6, and the end of the shovel blade 4 fits with the bottom of the litter box 2, which can also clean the cat feces as cleanly as possible.

[0035] In this embodiment, the toilet bowl 6 is detachably arranged on the housing 1 through a snap-fit ​​structure, and abuts against the end of the sand basin 2. The sand basin 2 is fixed by the toilet bowl 6, and both the toilet bowl 6 and the sand basin 2 can be disassembled for easy cleaning.

[0036] On the basis of the above embodiment, further, at least one concave-convex portion 21 is provided at the bottom of the litter box 2 near the toilet bowl 6. The concave-convex portion 21 can be convex or concave. When the shovel blade 4 is close to the toilet bowl 6, due to the setting of the concave-convex portion 21, the shovel blade 4 will slightly rotate upward or downward. At this time, more cat litter on the shovel blade 4 will fall down to avoid shoveling more cat litter into the toilet bowl 6.

[0037] Furthermore, the shovel blade 4 includes a mesh blade surface 41 and a door opening arc wall 42. The door opening arc wall 42 is arranged on both sides of the blade surface 41 and is higher than the blade surface 41. The door opening arc wall 42 can contact the toilet cover 7. When the shovel blade 4 reaches the front end of the litter box 2, the door opening arc walls 42 at both ends of the shovel blade 4 will push the toilet cover 7 open. The shovel blade 4 continues to move forward and the toilet cover 7 will be pushed open further. When the shovel blade 4 passes over the front end of the litter box 2, the shovel blade 4 will tilt downward under the action of the torsion spring and gravity until all the cat feces are poured out. When the shovel blade 4 retreats, the toilet cover 7 will cover the toilet 6 back and have a certain degree of sealing to prevent the odor from overflowing.

[0038] In addition, a disinfection device is provided under the carriage 5; an ultraviolet disinfection lamp is provided under the carriage 5, and ultraviolet disinfection is performed while shoveling feces. In this embodiment, a circuit board, a battery and a sensing device are also provided in the housing 1, and the carriage 5, the disinfection device, the battery and the sensing device are all connected to the circuit board. A battery is provided in the machine, and the battery can be removed and charged. With such a function, the device can work independently even if it is far away from a power source. The sensing device is used to sense the position of the cat. When the sensor senses that the cat has come, it starts to shovel cat feces after a set delay time (giving cat litter absorption time). Under the push of the pushing carriage 5, the shovel blade 4 is pressed against the bottom of the cat litter box by the torsion spring and starts to shovel, pushes forward a certain distance, and then retreats a certain distance, and so on.

[0039] The above is a detailed introduction to a cat litter box provided in an embodiment of the present invention. For a person skilled in the art, according to the idea of ​​the embodiment of the present invention, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
