Description

Technical Field

[0001] This application relates to the field of pet supplies technology, and more particularly to a cat litter cleaning device. Background Technology

[0002] As people's living standards continue to improve, they are beginning to pursue a richer spiritual life, and many choose to add color to their lives by keeping pets. Cats, due to their inherent characteristics, have become the preferred pet.

[0003] Currently, cat litter boxes are used to hold cat litter for cats to excrete. In order to facilitate the cleaning of cat litter, existing technologies use a moving mechanism and a lifting mechanism to drive the cat litter scoop to move horizontally and vertically in the cat litter box and rotate the cat litter scoop to scoop the cat litter into the collection space. However, cat feces in the collection space are easily exposed to the air, affecting the surrounding air environment and reducing the user experience. Utility Model Content

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a cat litter cleaning device.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] This application provides a cat litter cleaning device, comprising:

[0007] The shell has a litter box and a waste collection box arranged sequentially along its length. The waste collection box includes a box body and a cover body, and the cover body is rotatably mounted on the box body.

[0008] A motion module is disposed on the side of the housing and is capable of reciprocating along the length of the housing;

[0009] A moving mechanism is disposed on the motion module, and the moving mechanism is used to drive the motion module to reciprocate along the length direction of the housing;

[0010] A lifting mechanism is provided in the motion module and can reciprocate along the height direction of the housing;

[0011] The rotating mechanism includes a rotating drive, a swing arm, and an arc-shaped rack. The arc-shaped rack is fixed on the lifting mechanism. When the lifting mechanism reciprocates along the height direction of the housing, it drives the rotating mechanism to reciprocate along the height direction of the housing. The rotating drive is disposed on the swing arm, and the output end of the rotating drive meshes with the arc-shaped rack. When the rotating drive rotates, it drives the swing arm to reciprocate clockwise or counterclockwise.

[0012] The litter rake is fixed to the end of the swing arm away from the arc-shaped rack and swings back and forth clockwise or counterclockwise with the swing arm. A part of the litter rake is located inside the litter bin, and the litter rake is provided with a support part.

[0042] like Figure 1 As shown, an embodiment of this application provides a cat litter cleaning device 100, which is mainly used to clean feces from cat litter.

[0043] Combination Figures 2 to 4 As shown, the cat litter cleaning device 100 includes a housing 120, a motion module 110, a moving mechanism 130, a lifting mechanism 140, a rotating mechanism 150, and a cat litter rake 160.

[0044] Combination Figure 5 As shown, a litter bin 121 and a waste collection box 122 are sequentially arranged along the length of the shell 120. The waste collection box 122 includes a box body 1221 and a cover 1222, with the cover 1222 rotatably mounted on the box body 1221. The side of the cover 1222 away from the litter bin 121 is rotatably connected to the box body 1221. If the cover 1222 is rotatably connected to the box body 1221 via a pivot 123, it can close the opening 12211 of the box body 1221.

[0045] Continue reading Figure 2 and Figure 4 As shown, the motion module 110 is disposed on the side of the housing 120 and is capable of reciprocating along the length of the housing 120. A moving mechanism 130 is disposed on the motion module 110 and is used to drive the motion module 110 to reciprocate along the length of the housing 120. Exemplarily, a guide rack 1201 is provided at the bottom of the housing 120. The moving mechanism 130 includes a transverse motor 131 and an output gear 132. The output gear 132 is meshed with the guide rack 1201, and the output end of the transverse motor 131 is fixedly connected to the output gear 132, for driving the output gear 132 to move along the guide rack 1201.

[0046] Understandably, two racks can be provided, spaced apart at the bottom of the housing 120. Two output gears 132 are also provided and connected via a synchronous shaft 170. The motor drives the output gears 132 to move along the racks. This ensures the synchronicity of the movement of the motion modules 110 on both sides of the housing 120.

[0047] Of course, in other embodiments, the moving mechanism 130 includes a transverse motor 131, a driving wheel, and a driven wheel. The driving wheel and the driven wheel are connected by a racetrack-shaped belt. The driven wheel is rotatably mounted on the bottom of the housing 120. The output end of the motor is connected to the driving wheel to drive its rotation. The motion module 110 is mounted on the belt. The motor can rotate forward and backward to enable the motion module 110 to move along the length of the housing 120.

[0048] Combination Figure 4 , Figure 9 and Figure 11As shown, the lifting mechanism 140 is disposed on the motion module 110 and can reciprocate along the height direction of the housing 120. The lifting mechanism 140 includes a lifting motor 141, a gear 142, a moving rack 143, and a bracket 144. The lifting motor 141 is fixed on the motion module 110, and the moving rack 143 is fixed on the bracket 144. The top of the motion module 110 has an opening. The output end of the lifting motor 141 is fixedly connected to the gear 142. The gear 142 meshes with the rack. The lifting motor 141 drives the gear 1511 to rotate, thereby moving the moving rack 143, which in turn moves the bracket 144 along the height direction of the housing 120.

[0049] Combination Figure 4 and Figure 9 As shown, the rotating mechanism 150 includes a rotating drive 151, a swing arm 152, and an arc-shaped rack 153. The arc-shaped rack 153 is fixed on the lifting mechanism 140. When the lifting mechanism 140 reciprocates along the height direction of the housing 120, it drives the rotating mechanism 150 to reciprocate along the height direction of the housing 120. The rotating drive 151 is disposed on the swing arm 152, and the output end of the rotating drive 151 meshes with the arc-shaped rack 153. When the rotating drive 151 rotates, it drives the swing arm 152 to reciprocate clockwise or counterclockwise. For example, a drive gear 1511 is fixed to the output end of the rotating drive 151, and the drive gear 1511 meshes with the arc-shaped rack 153.

[0050] Combination Figure 3 As shown, one end of the litter rake 160 passes through the opening of the motion module 110 and is fixed to the end of the swing arm 152 away from the arc-shaped rack 153. The litter rake 160 swings back and forth clockwise or counterclockwise following the swing arm 152. A part of the litter rake 160 is located inside the litter bin 121, and the litter rake 160 is provided with a support part 161. When the support part 161 abuts against the cover 1222, the litter rake 160 can flip the cover 1222 under the action of the lifting mechanism 140 and the rotating mechanism 150, so as to rake out the feces in the litter bin 121 and push them into the box 1221.

[0051] For example, the motion module 110 moves towards the litter box 122 under the action of the moving mechanism 130 until the support part 161 of the litter rake 160 abuts against the cover 1222. At this time, the moving mechanism 130 stops moving, and the lifting mechanism 140 rises along the height of the housing 120 to drive the litter rake 160 to lift the cover 1222. At the same time, the feces on the litter rake 160 can fall into the box 1221 through the opening 12211. Then, the lifting mechanism 140 descends to the initial position along the height direction of the housing 120. At this time, the cover 1222 rotates under the action of gravity to seal the box 1221. Meanwhile, the moving mechanism 130 can drive the motion module 110 to move away from the litter box 122. Of course, when the motion module 110 moves closer to the litter box 122 under the action of the moving mechanism 130 until the support part 161 of the litter rake 160 abuts against the cover 1222, the litter rake 160 can also be driven to rotate by the rotating mechanism 150 to lift the cover 1222, and then the litter rake 160 can be driven to rise by the lifting mechanism 140, or the lifting mechanism 140 and the rotating mechanism 150 can work simultaneously to lift and rotate the litter rake 160, so as to lift the cover 1222 and push the cat's feces into the box 1221.

[0052] It should be noted that there are two motion modules 110, which are respectively arranged on opposite sides of the housing 120 in the width direction, and the two motion modules 110 are connected by a synchronous shaft 170. There are also two lifting mechanisms 140. The lifting mechanism 140 with the rotating mechanism 150 is fixed on one side of the housing 120 and is connected to the gear 142 of the lifting mechanism 140 on the other side of the housing 120 through the synchronous shaft 170. The synchronous shaft 170 and the gear 142 adopt an interference fit. During the rotation of the lifting motor 141, it drives the gear 142 of the two lifting mechanisms 140 to move synchronously, so as to ensure the synchronicity of the movement of the lifting mechanism 140.

[0053] The cat litter cleaning device 100 provided in this application's embodiments drives the motion module 110 to reciprocate along the length of the housing 120 via a moving mechanism 130. Simultaneously, a lifting mechanism 140 drives the rotating mechanism 150 to reciprocate along the height of the housing 120. The litter rake 160 is fixed to the swing arm 152 of the rotating mechanism 150. A rotating drive component 151 drives the swing arm 152 to rotate along the arc-shaped rack 153. When the litter rake 160 rises or rotates, the support part 161 lifts the cover 1222, allowing the litter rake 160 to push feces into the box 1221. When the litter rake 160 moves away from the cover 1222, the cover 1222 rotates under gravity to seal the box 1221, reducing the evaporation of fecal odor from the collection box 122. This facilitates cleaning cat feces, reduces odor generation, and improves the user experience.

[0054] like Figure 3 As shown, in some embodiments, the end of the cover 1222 near the litter box 121 is provided with an abutment portion 1223 that cooperates with the support portion 161, and the support portion 161 can abut against the abutment portion 1223. In this embodiment, by providing the abutment portion 1223 on the cover 1222 that cooperates with the support portion 161, it is convenient for the support portion 161 to lift and flip the cover 1222 to open the litter box 122.

[0055] In the above embodiment, the projection of a portion of the abutment portion 1223 onto the plane of the litter box 121 is located inside the litter box 121. In this embodiment, a portion of the abutment portion 1223 is located inside the litter box 121, which facilitates the abutment portion 1223 to abut against the support portion 161, so that when the cover 1222 is flipped over, the feces on the litter rake 160 can be pushed into the box 1221.

[0056] like Figure 7 and Figure 8 As shown, in some embodiments, the abutment portion 1223 is an abutment groove, which is provided with a first groove 12231 along the length direction of the housing 120 and a second groove 12232 along the height direction of the housing 120. The first groove 12231 is arranged towards the cat litter rake 160, and the first groove 12231 and the second groove 12232 are connected. The second groove 12232 is arranged downward. In this embodiment, the abutment portion 1223 is an abutment groove, and the support portion 161 can abut against the groove body of the abutment groove through the first groove 12231, so that the cat litter rake 160 can abut against the abutment groove when it moves to the cover 1222, thereby flipping the cover 1222 under the action of the lifting mechanism 140 and the rotating mechanism 150.

[0057] like Figure 6 and Figure 8 As shown, in some embodiments, the litter box 121 has a first connecting portion 1211 at one end near the box body 1221, and a second connecting portion 12233 is provided in the abutment groove, the second connecting portion 12233 engaging with the first connecting portion 1211. Exemplarily, the first connecting portion 1211 is a locking hole, and the second connecting portion 12233 is a positioning post; the positioning post engages with the locking hole to facilitate the connection between the cover 1222 and the box body 1221.

[0058] Of course, in other embodiments, the first connecting part 1211 and the second connecting part 12233 can both be magnets, or the first connecting part 1211 can be an iron part and the second connecting part 12233 can be a magnetic part, or the first connecting part 1211 can be a magnetic part and the second connecting part 12233 can be an iron part.

[0059] like Figure 5 and Figure 6As shown, in some embodiments, the wall of the litter bin 121 near the housing 1221 is an arc-shaped wall 1212, and the height of the arc-shaped wall 1212 along the height direction of the housing 120 is less than the height of the side walls of the litter bin 121 along the length direction of the housing 120. In this embodiment, the arc-shaped wall 1212 facilitates the dispensing of feces into the housing 1221 when the litter rake 160 rotates or moves up and down; that is, the litter rake 160 rotates along the arc-shaped wall 1212 to dispense feces into the housing 1221. Simultaneously, the side walls on both sides of the arc-shaped wall 1212 are higher than the height of the arc-shaped wall 1212 to prevent feces from slipping off the sides.

[0060] like Figure 5 and Figure 6 As shown, in some embodiments, the first connecting portion 1211 is disposed at the top end of the arc-shaped wall 1212. In this embodiment, the first connecting portion 1211 is disposed at the top end of the arc-shaped wall 1212, so that when the support portion 161 abuts against the abutting portion 1223, the first connecting portion 1211 and the second connecting portion 12233 can be easily separated under the action of the lifting mechanism 140 and the rotating mechanism 150.

[0061] like Figure 5 and Figure 6 As shown, in some embodiments, comb teeth 1213 are provided on the arc-shaped wall 1212. The comb teeth 1213 extend along the length of the housing 120 and are located above the box body 1221. In this embodiment, the comb teeth 1213 are provided so that when the cat litter rake 160 rotates, feces are pushed into the box body 1221 from the comb teeth 1213.

[0062] like Figure 5 As shown, in some embodiments, the rake bars of the cat litter rake 160 near the litter bin 121 include a first bent portion 1611 and a second bent portion 1612, which are connected to form a support portion 161. In this embodiment, the support portion 161 is formed by bending the first bent portion 1611 and the second bent portion 1612, which facilitates manufacturing.

[0063] like Figure 5 As shown, in some embodiments, the first bend 1611 is a straight segment, and the second bend 1612 is an arc segment. One end of the straight segment and one end of the arc segment are connected by a circular transition, and the other end of the straight segment is connected to the rake bar. In this embodiment, the support 161 is defined by the connection of the straight segment and the arc segment to form a crescent shape, so that the tip of the crescent shape abuts against the cover 1222.

[0064] like Figure 2 and Figure 5As shown, in some embodiments, the waste collection box 122 also includes a side cover 1224, which is disposed on the side away from the litter box 121, and the side cover 1224 is detachably connected to the box body 1221. When it is necessary to clean the feces in the waste collection box 122, the feces in the box body 1221 can be removed by opening the side cover 1224.

[0065] like Figure 9 and Figure 10 As shown, in any of the above embodiments, the end of the swing arm 152 away from the arc-shaped rack 153 is rotatably connected to the bracket 144 and has a mounting groove 1521. The cat litter rake 160 is provided with a connecting rod 162, the end of the connecting rod 162 is bent to form a connecting part 1621, and the connecting part 1621 is interference-fitted into the mounting groove 1521 so that the cat litter rake 160 can be rotated when the swing arm 152 rotates.
