[0042] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0043] The utility model provides a cat litter box with a semi-automatic excrement shoveling function. The manufacturing cost of the cat litter box is low, the excrement shoveling steps are simple, and the time of the user in cleaning the cat litter box is saved.

[0044] Example 1:

[0045] Reference Figures 1 to 14 This embodiment provides a semi-automatic cat litter box with poop shoveling function, comprising a shell 1, a litter bin 2 and a poop shoveling assembly 3, wherein the shell 1 is arranged on the periphery of the litter bin 2.

[0046] Reference Figure 1 、 Figure 2 and Figure 8 A first opening 10 is provided in the middle of the shell 1 for the cat to enter the litter bin 2, and a second opening 12 is provided at one end of the shell 1 for the litter bin 2 to pass through. Under the action of external force, the shell 1 and the litter bin 2 can move relative to each other.

[0047] Reference Figure 1 、 Figure 4 and Figure 7 In this embodiment, a waste bin 20 is provided at one end of the sand bin 2 away from the second opening 12 , and the poop shoveling assembly 3 is provided at one end of the housing 1 close to the second opening 12 .

[0048] Refer to 1. Figure 2 and Figure 11 Furthermore, one end of the poop scooping assembly 3 is hinged to the housing 1, and the other end of the poop scooping assembly 3 is provided with a first tooth structure 310. The first tooth structure 310 extends into the litter bin 2 and is used to shovel waste in the litter bin 2. It should be noted that the spacing between adjacent racks in the first tooth structure 310 is smaller than the average size of cat feces, so that cat feces cannot pass through the first tooth structure 310, ensuring that the poop scooping assembly 3 can scoop cat feces cleanly.

[0049] For the convenience of description, the end of the litter bin 2 away from the waste bin 20 is set as the head end, and the end of the litter bin 2 close to the waste bin 20 is set as the tail end. The method of using the semi-automatic cat litter box provided in this embodiment is as follows:

[0050] When cat feces need to be scooped, the user grasps the front end of the sand bin 2 and pulls the sand bin 2 out along the second opening 12, causing the sand bin 2 and the housing 1 to move relative to each other. Using the sand bin 2 as a reference, the feces scooping assembly 3 moves along with the housing 1. Specifically, the feces scooping assembly 3 moves from the front end of the sand bin 2 to the rear end of the sand bin 2, and finally into the waste bin 20. During this movement, the first tooth-like structure 310 scoops cat feces from the sand bin 2 into the waste bin 20, completing the feces scooping process.

[0051] After shoveling cat litter, the user pushes the litter bin 2 along the second opening 12 to the inner periphery of the housing 1. The housing 1 and the litter bin 2 are relatively displaced. With the litter bin 2 as a reference, the litter shoveling assembly 3 moves along the housing 1 along the waste bin 20 to the head end of the litter bin 2. The first tooth-like structure 310 can smooth the cat litter during movement, preventing the litter from accumulating at the end of the litter bin 2.

[0052] Compared to manual litter boxes on the market, the litter box provided by this embodiment simplifies shoveling, requiring only a push and a pull to complete the shoveling function, saving the user time. Compared to fully automatic litter boxes on the market, the litter box provided by this embodiment does not require an electrical control component, thus controlling production costs and enabling consumers to purchase the litter box provided by this embodiment at a relatively low price. In summary, the litter box provided by this embodiment combines the convenience of shoveling with the advantage of being inexpensive, making it highly competitive in the market.

[0053] Reference Figure 12 In this embodiment, a first guide rail 13 is provided on the side of the housing 1 facing the sand bin 2. A first pulley 21 is provided on the side of the housing 1 facing the sand bin 2. The first pulley 21 is disposed in the first guide rail 13. The first guide rail 13 is a horizontal linear guide rail. When a user pulls the sand bin 2 to move, the first pulley 21 moves along the first guide rail 13. In this embodiment, the first guide rail 13 and the first pulley 21 provide guidance for the movement of the sand bin 2.

[0054] Reference Figure 3, second pulleys 22 are provided on both sides of the bottom of the head end of the litter bin 2. When the cat litter box in this embodiment is placed on the ground for use, when the user pulls the litter bin 2 to move, the second pulley 22 can generate a small rolling friction with the ground, and combined with the first pulley 21 described above, a small rolling friction can be generated between the litter bin 2 and the shell 1. Even when the litter bin 2 is full of cat litter, the user only needs to use very little force to pull the litter bin 2.

[0055] Reference Figure 3 、 Figure 4 as well as Figure 7 The head end of the sand bin 2 is provided with a grab plate 23 extending toward the bottom of the sand bin 2, and a gap 230 is provided between the grab plate 23 and the head end of the sand bin 2. The gap 230 here can provide sufficient gripping space for the user. The user can put his hand into the gap 230 and grab the grab plate 23, and then pull the sand bin 2.

[0056] Reference Figure 11 The poop scooping assembly 3 includes a connecting frame 30 and a poop scooping plate 31. In this embodiment, the poop scooping plate 31 is made of plastic. Compared with other materials, the cost of plastic is relatively low, and the surface of plastic is smooth and easy to wipe and clean, which helps to maintain the hygiene of the poop scooping plate 31. In another specific embodiment, the poop scooping plate 31 can be made of a combination of plastic and metal. Compared with using a pure plastic material, the combination of plastic and metal can provide higher durability and wear resistance, thereby extending the service life of the poop scooping plate 31.

[0057] In this embodiment, the connecting frame 30 is made of a combination of acrylonitrile-butadiene-styrene copolymer resin (ABS resin) and 30% glass fiber. Because ABS resin has excellent processing properties, it remains easy to mold and process when combined with glass fiber. Furthermore, the glass-fiber-reinforced ABS resin provides a smoother and more aesthetically pleasing appearance, giving the connecting frame 30 a more premium appearance. In another embodiment, the connecting frame 30 is made of a composite metal or directly die-cast from an aluminum alloy, providing greater strength and durability.

[0058] The connecting frame 30 includes a first beam 301 and movable bars 304 provided at both ends of the first beam 301 . The excrement scooping plate 31 is connected to the first beam 301 . The first tooth structure 310 is provided at one end of the excrement scooping plate 31 away from the first beam 301 .

[0059] The first crossbeam 301 is provided with a protruding structure 302, and the shit scooping board 31 is provided with a groove 311, and the groove 311 is adapted to the protruding structure 302. A cavity is provided inside the first crossbeam 301 (not shown in the figure), and a movable seat 303 is provided on the protruding structure 302. The movable seat 303 can move toward the direction of the cavity. A fixing hole 312 is provided on one side of the groove 311 of the shit scooping board 31, and the fixing hole 312 is adapted to the contour of the movable seat 303.

[0060] The assembly process of the poop scooping assembly 3 is as follows: the movable seat 303 is pressed toward the cavity by the side wall of the groove 311, and the protruding structure 302 is inserted into the groove 311. After the insertion is in place, the movable seat 303 is inserted through the fixing hole 312, and the poop scooping plate 31 is fixed to the connecting frame 30. The poop scooping assembly 3 is configured as an assembled type, which makes it convenient for the user to disassemble the poop scooping plate 31 for cleaning.

[0061] In this embodiment, the poop shoveling component 3 is set to a symmetrical structure, and the movable bar 304 on one side is taken as an example for explanation. One end of the movable bar 304 is hinged to the shell 1, and the other end of the movable bar 304 is provided with a third pulley 305. The side of the sand bin 2 is provided with a second guide rail 24, and the third pulley 305 is provided in the second guide rail 24 and can move along the second guide rail 24.

[0062] It should be noted that the first pulley 21, the second pulley 22 and the third pulley 305 in this embodiment are all rubber wheels. Compared with metal wheels, rubber wheels produce less noise when rolling, which can provide a relatively quiet and comfortable environment for cats. In addition, rubber wheels have strong wear resistance and can maintain good working condition for a long time.

[0063] Reference Figure 4 、 Figure 6 、 Figure 10 as well as Figure 12 The second guide rail 24 includes a first rail 240 and a second rail 241. The end of the first rail 240 is connected to the head end of the second rail 241. The head end of the second rail 241 is set as a "X" structure, and the end of the second rail 241 is set as a horizontal rail. The end of the sand bin 2 close to the second rail 241 is set as an upward extending arc structure 25.

[0064] Reference Figure 13The arc structure 25 is provided with a second tooth structure 250 at one end near the waste bin 20. The second tooth structure 250 is arranged alternately with the first tooth structure 310. When the excrement scooping plate 31 moves to the end of the arc structure 25, the second tooth structure 250 can extend into the adjacent rack gap 230 of the first tooth structure 310 to clean cat feces remaining on the first tooth structure 310.

[0065] Reference Figure 10 In this embodiment, an isolation section 2401 is provided in the middle of the first track 240, and the isolation section 2401 divides the first track 2400 into a first channel 2402 and a second channel 2403. The first channel 2402 is located above the second channel 2403, and the first channel 2402 and the second channel 2403 are roughly parallel. The head end of the first channel 2402 is connected with the head end of the second channel 2403, and the end of the first channel 2402 is connected with the end of the second channel 2403. The end of the isolation section 2401 close to the end of the first channel 2402 is provided with a rotating shaft 2404, and the rotating shaft 2404 is provided with a return bracket 2405.

[0066] In this embodiment, the first channel 2402 and the second channel 2403 are substantially parallel. A linear chute connects the first and second ends of the first and second channels 2402 and 2403, respectively, and an arcuate chute connects the first and second ends of the first and second channels 2402 and 2403, respectively. The first end of the second channel 2403 is closer to the front end of the sand bin 2, and the linear chute extends toward the front end of the sand bin 2.

[0067] In the absence of external force, the return bracket 2405 will abut against the side wall of the arc-shaped slide groove and be in a horizontal state, so that the first channel 2402 is connected to the second track 241; when external force is applied, the return bracket 2405 can rotate upward with the rotating shaft 2404 as the center, so that the second channel 2403 is connected to the second track 241.

[0068] In the initial state, the shell 1 covers the sand bin 2, and the third pulley 305 in the shit shoveling assembly 3 is located at the head end of the second channel 2403 under the action of gravity.

[0069] Reference Figure 13The user pulls the sand bin 2 to move horizontally along the first guide rail 13. Taking the sand bin 2 as a reference, the third pulley 305 moves along the second channel 2403. At the same time, the excrement shoveling plate 31 shovels the cat excrement in the sand bin 2 toward the waste bin 20. When the third pulley 305 moves to the arc-shaped chute, the return bracket 2405 can be pushed upward, so that the second channel 2403 is connected to the second track 241. The third pulley 305 continues to move along the head end of the second track 241 to the end, shoveling the cat excrement into the waste bin 20.

[0070] Reference Figure 14 After the cat feces are removed, the user pushes the litter bin 2 to return to its initial state, and the third pulley 305 moves along the end of the second track 241 to the head end of the second track 241. At this time, the return bracket 2405 returns to the horizontal position under the action of gravity, and the third pulley 305 enters the second channel 2403 along the top of the return bracket 2405 and continues to move to the head end of the second channel 2403. Since the head end of the second channel 2403 is connected to the head end of the first channel 2402 through a linear slide groove, under the action of gravity, the poop shoveling component 3 will slide along the linear slide groove into the head end of the second channel 2403.

[0071] It can be understood that, taking the sand bin 2 as a reference, when the sand bin 2 is pulled, the poop shoveling assembly 3 moves along the second channel 2403 located below, and most of the first tooth structure 310 of the poop shoveling plate 31 extends into the sand bin 2, shoveling the cat feces buried in the sand bin 2; and when the sand bin 2 is pushed to its original position, the poop shoveling assembly 3 moves along the first channel 2402 located above, and only a small part of the first tooth structure 310 of the poop shoveling plate 31 extends into the sand bin 2, smoothing the cat litter on the surface of the sand bin 2.

[0072] In another embodiment, the first track 240 is configured as a horizontal guide rail, the end of which is connected to the beginning of the second track 241. The ends of the first track 240 and the second track 241 are approximately at the same height. When the sand bin 2 is pulled, the third pulley 305 at the bottom of the feces scooping assembly 3 moves along the beginning of the first track 240 to the end of the second track 241. When the sand bin 2 is pushed to its original position, the third pulley 305 at the bottom of the feces scooping assembly 3 moves along the end of the second track 241 to the beginning of the first track 240.

[0073] Reference Figure 10 as well as Figure 12In this embodiment, a second crossbeam 26 and a third crossbeam 27 are provided at the end of the sand bin 2. The second crossbeam 26 is located at the top of the sand bin 2, and the third crossbeam 27 is located at the bottom of the sand bin 2. The first crossbeam 301 is provided with a locking portion 260. The top of the waste bin 20 is provided with a slot 201 that matches the locking portion 260. A third opening 28 is provided at the end of the sand bin 2. The waste bin 20 can be inserted between the first crossbeam 301 and the second crossbeam 26 along the third opening 28. The second crossbeam 26 is supported at the bottom of the waste bin 20. The locking portion 260 and the slot 201 are engaged and locked, securing the waste bin 20 to the end of the sand bin 2.

[0074] When using the cat litter box provided by the present invention, the user can directly collect cat feces in the waste bin 20, and after the waste bin 20 is full, take out the waste bin 20 from the tail of the litter bin 2 to clean the waste bin 20; the user can also put a garbage bag in the waste bin 20, collect cat feces in the garbage bag, and take out and discard it after the garbage bag is full.

[0075] Furthermore, a sealing gasket (not shown) is provided on the side of the housing 1 facing the waste bin 20. When the housing 1 covers the sand bin 2 and the waste bin 20, the sealing gasket can isolate the waste bin 20 from the external environment, preventing odor inside the waste bin 20 from leaking into the external environment. In another embodiment, the sealing gasket is provided on the side of the waste bin 20 facing the housing 1.

[0076] Reference Figure 1 、 Figures 9 and 10 In this embodiment, an integrally formed sand guard plate 11 is provided at the first opening 10 of the shell 1. The sand guard plate 11 includes a first surface 110, a second surface 111 and a third surface 112 connected in sequence. For the convenience of description, the end of the shell 1 provided with the poop shoveling component 3 is used as the front side of the first opening 10. A sand leakage net 113 is provided on the front side of the first opening 10. The first surface 110 is connected to the left side of the first opening 10, the second surface 111 is connected to the rear side of the first opening 10, and the third surface 112 is connected to the right side of the first opening 10.

[0077] Specifically, a first latch 114 is provided at the bottom of the first surface 110 and the third surface 112, and a second latch 116 is provided at the ends of the first surface 110 and the third surface 112. First slots 115 corresponding to the first latch 114 are provided on the left and right sides of the first opening 10, and a second slot 117 corresponding to the second opening 12 is provided on the front side of the first opening 10. The sand deflector 11 is connected to the housing 1 by the first latch 114 engaging with the first slot 115, and the second latch 116 engaging with the second slot 117. When a cat enters the sand bin 2 through the first opening 10 and moves within the bin 2, the cat litter within the bin 2 may splash. The sand deflector 11 blocks the splashing of cat litter from three directions of the first opening 10, while the sand filter 113 on the front flushes the splashed cat litter back into the bin 2, avoiding waste.

[0078] Furthermore, users can customize transparent or translucent sand guard boards 11 according to personal needs. The transparent sand guard boards 11 will not block the user's sight, and can facilitate the user to observe the situation in the sand bin from multiple angles, while the translucent sand guard boards 11 can provide cats with a relatively hidden environment, making them feel safer and more comfortable.

[0079] Example 2:

[0080] Reference Figure 15 The difference between this embodiment and embodiment 1 is that the head end of the first channel 2402 is connected to the head end of the second channel 2403 through an arc-shaped chute, the head end of the first channel 2402 is closer to the head end of the sand bin 2, and the arc-shaped chute extends toward the middle of the sand bin 2.

[0081] In the first embodiment, after the excrement shoveling work is completed, the user pushes the sand bin 2 back to its original position, and the excrement shoveling assembly 3 and the sand bin 2 also return to their initial positions together. Under the action of gravity, the excrement shoveling assembly 3 should slide into the head end of the second channel 2403.

[0082] However, as the poop scooping assembly 3 moves from the rear end of the litter bin 2 toward the front end, it may also carry some of the cat litter with it. The closer the area is to the front end of the litter bin 2, the more likely cat litter will accumulate. This accumulated cat litter creates resistance for the poop scooping assembly 3. If the resistance is too great, the poop scooping assembly 3 will not slide smoothly into the front end of the second channel 2403. If the user pulls the litter bin 2 in this situation, the poop scooping assembly 3 will not slide properly along the second channel 2403, thus hindering the smooth operation of the poop scooping operation.

[0083] In view of this, in this embodiment, the arc-shaped chute is designed to extend toward the middle of the litter bin 2. The closer it is to the middle of the litter bin 2, the more evenly the cat litter is distributed, and the less resistance the cat litter exerts on the poop scooping assembly 3. In this way, the poop scooping assembly 3 can slide smoothly into the head end of the second channel 2403, fully prepared for the next poop scooping.

[0084] It is understandable that those skilled in the art can, under the guidance of the above embodiments, combine various implementation methods in the above embodiments to obtain technical solutions of multiple implementation methods.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
