Description

Technical Field

[0001] This utility model relates to the technical field of pet litter boxes, and in particular to a push-pull type pet litter box. Background Technology

[0002] As people's living standards improve, their demands for spiritual life also gradually increase. More and more people are keeping pets (such as cats, rabbits, or dogs), and consequently, the demand for smart pet litter boxes for collecting urine and feces is also increasing. Currently, there is a type of flat-push pet litter box. Taking cat litter box as an example, the pet litter box is used with cat litter as a toilet for cats. When using it, cat litter needs to be poured into the litter box beforehand. The cat urinates and defecates in the litter box, and the urine and feces will mix with the cat litter to form a litter ball. After the cat finishes using the toilet and leaves, the litter cleaning component will move in a straight line under the drive mechanism to push the litter ball containing urine and feces into the litter collection chamber on one side, where the litter collection chamber collects the litter ball containing urine and feces. Current push-type pet litter boxes do not have a toilet safety detection function. When the cleaning component moves horizontally, the cat may jump back into the litter box, or another cat may jump into the litter box. At this time, there is a risk that the cleaning component will pinch and injure the cat. Moreover, the drive mechanism used to move the cleaning component is prone to damage because it can be stuck by the cat. Therefore, the existing push-type pet litter boxes need to be improved.

[0003] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

The drive gear is connected to the motor and meshes with the transmission gear. Both ends of the transmission rod in the length direction are sleeved and fixed with the traveling gear, which meshes with a corresponding rack.

[0019] In one of the technical solutions, flexible dustproof strips are provided on both sides of the groove opening of the sand trough along the second direction. The dustproof strips are located inside the rack to separate the rack and the sand trough. The upper or lower end of the dustproof strip is fixedly connected to the housing. The transmission rod passes through the dustproof strip to the top or bottom of the rack.

[0020] Compared with the prior art, the flat-push pet litter box provided by this utility model has at least the following beneficial effects:

[0021] During use, after the pet normally uses the litter box and leaves, the cleaning component moves along the first direction to clean or reset in the opposite direction, driven by the drive mechanism. If a pet enters the litter box during this movement, it will be detected by either the first or second sensor. If either the first or second sensor detects that a pet has entered the litter box, it will transmit this information to the main control board, which will then control the drive mechanism to stop. This will keep the cleaning component in a stopped state, ensuring it does not continue to move and harm the pet. Only when neither the first nor the second sensor detects a pet will the drive mechanism resume driving the cleaning component to clean along the first direction or reset in the opposite direction. This design ensures the safety of pets when using the litter box and improves the user experience. Attached Figure Description

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0042] Please refer to the following: Figure 1 , Figures 3 to 7 This utility model provides a push-type pet litter box, mainly including a shell 1, a litter collection chamber 2, a drive mechanism 3, and a litter cleaning component 4. The shell 1 has an upward-opening litter trough 11 for holding litter for pets to use. The litter collection chamber 2 has a litter collection trough 21 for collecting litter clumps containing urine and feces from the litter trough 11. The litter collection chamber 2 is detachably connected to the shell 1 so that the user can periodically pull out the litter collection chamber 2 and remove the litter clumps inside. The litter collection trough 21 is set at an adjacent position to the litter trough 11 along a first direction X. The litter cleaning component 4 extends into the litter trough 11 and is slidably connected to the shell 1 along the first direction X, either directly or indirectly through connecting other components. The drive mechanism 3 is connected to the shell 1 and the litter cleaning component 4 respectively, and is used to drive the litter cleaning component 4 to reciprocate linearly along the first direction X.

[0043] Taking cat use as an example, when using the litter box 11, cat litter needs to be poured into the litter box 11 beforehand. The cat defecates and urinates in the litter box 11, and the feces and urine will mix with the cat litter to form a litter ball. After the cat finishes using the litter box and leaves, the litter cleaning component 4 will move in a straight line along the first direction X under the drive of the drive mechanism 3. The litter cleaning component 4 pushes the litter ball containing feces and urine into the litter collection chamber 2 on one side, and the litter collection chamber 2 collects the litter ball containing feces and urine. After the litter cleaning is completed, the litter cleaning component 4 will return to the initial position in the opposite direction of the first direction X under the drive of the drive mechanism 3.

[0044] Please refer to the following: Figure 3 and Figure 4The push-type pet litter box in this embodiment also includes a first sensor 5 and a second sensor 6. During the movement of the litter cleaning component 4 in the litter trough 11, the litter trough 11 is actually divided into a first space 111 and a second space 112. The first space 111 and the second space 112 are arranged adjacent to each other along the first direction X. The first sensor 5 and the second sensor 6 are set on the housing 1 or on the litter cleaning component 4. The first sensor 5 is used to detect the biological feature information in the first space 111, and the second sensor 6 is used to detect the biological feature information in the second space 112. The first sensor 5 and the second sensor 6 are both signal connected to the aforementioned drive mechanism 3. Specifically, during the movement of the litter cleaning component 4 along the first direction X, if a pet enters the litter box 11, the pet will be detected by either the first sensor 5 or the second sensor 6. As long as either the first sensor 5 or the second sensor 6 detects that a pet has entered the litter box 11, the first sensor 5 or the second sensor 6 will transmit this information to the main control board 100, which will then control the drive mechanism 3 to stop operating. At this time, the litter cleaning component 4 can be controlled to be in a stopped state to ensure that the litter cleaning component 4 will not continue to move and harm the pet. Only when neither the first sensor 5 nor the second sensor 6 detects a pet will the drive mechanism 3 continue to drive the litter cleaning component 4 to clean along the first direction X or reset along the opposite direction of the first direction X. This solution ensures the safety of pets when using the toilet and improves the user experience.

[0045] Please refer to them again. Figure 3 and Figure 4 In this embodiment, the first sensor 5 is preferably fixed inside the housing 1 and located in the direction opposite to the stool collection chamber 2 of the stool cleaning assembly 4, and the second sensor 6 is preferably disposed on the side of the stool cleaning assembly 4 facing the stool collection chamber 2. In other embodiments, the first sensor 5 and the second sensor 6 may both be fixed on the stool cleaning assembly 4, or the first sensor 5 and the second sensor 6 may both be fixed inside the housing 1.

[0046] Please refer to the following: Figure 3 , Figure 6 and Figure 7The cleaning component 4 specifically includes a movable seat 41 and a shovel component 42. The movable seat 41 is slidably connected to the housing 1 along a first direction X. A drive mechanism 3 is connected to the movable seat 41 and drives the movable seat 41 to reciprocate along a straight line in the first direction X. The shovel component 42 extends into the sand trough 11 and is slidably connected to the movable seat 41 longitudinally. Preferably, the outer surface of the movable seat 41 has a longitudinally extending guide rail 411 protruding from the guide rail 411, and the shovel component 42 slides downwards from this guide rail 411. The housing 1... Guide grooves 12 are provided on both of the opposite inner sides. The bottom end of the guide grooves 12 extends to the path along which the scooping component 42 moves in the first direction X. The guide grooves 12 extend upward at an incline toward the collection chamber 2. The bottom surface of the litter trough 11 includes an inclined surface 113 that extends upward and gradually approaches the opening of the collection trough 21. The inclined surface 113 is preferably arc-shaped. In fact, this inclined surface 113 belongs to the second space 112. The second sensor 6 mentioned above is actually set on the side of the moving base 41 facing the collection chamber 2. Specifically, when the cat finishes using the litter trough 11, when the cleaning component 4 moves to the end in the first direction X under the drive of the drive mechanism 3, the scooping component 42 will slide into the guide groove 12 and move upward under the guidance of the guide groove 12. At the same time, the scooping component 42 will push the litter ball containing urine and feces upward along the inclined surface 113 until the litter ball containing urine and feces is pushed into the collection chamber 2 on one side. Through the above design, the shovel component 42 can only push sand clumps containing urine and feces into the feces collection chamber 2, while normal sand without urine and feces is almost never pushed into the feces collection chamber 2 by the shovel component 42, which helps to reduce the amount of sand consumed. Preferably, the end of the shovel component 42 in the second direction Y (the second direction Y is perpendicular to the first direction X) is connected to a freely rotatable roller 43. The roller 43 is designed to slide along the guide groove 12 to prevent mutual wear between the shovel component 42 and the groove wall of the guide groove 12, while improving the smoothness of the shovel component 42 sliding along the guide groove 12.

[0047] Please refer to the following: Figure 1 , Figures 3 to 5The push-type pet litter box in this embodiment also includes a door 200. The door 200 is rotatably connected to the housing 1 and automatically covers the opening of the waste collection trough 21 under its own weight to limit the outward diffusion of odorous gases inside the waste collection trough 2. The door 200 has a protruding drive part 201. When the scooping component 42 continues to move along the guide groove 12 in the first direction X, the scooping component 42 will push the door 200 upward by squeezing the drive part 201 to open the opening of the waste collection trough 21, so that the waste collection trough 21 can receive the litter containing urine and feces scooped by the scooping component 42. When the cleaning component 4 moves away from the waste collection trough 2 in the opposite direction of the first direction X, the door 200 will automatically fall down due to gravity and cover the waste collection trough 21 again. Based on the design with a compartment door 200, this embodiment has a first deodorizing box 7 on the compartment door 200. The first deodorizing box 7 contains a deodorizing agent and is used to deodorize the fecal collection tank 21. A second deodorizing box 8 is provided on the side of the movable seat 41 facing the fecal collection tank 2. The second deodorizing box 8 is used to deodorize the sand tank 11. Both the first deodorizing box 7 and the second deodorizing box 8 are detachable so that the user can fill them with deodorizing agent himself.

[0048] Please refer to the following: Figure 6 and Figure 7 The litter scooping component 42 includes a mounting base 421 and a litter scooping body 422. The mounting base 421 is slidably connected to the aforementioned movable base 41 in the longitudinal direction via a connecting guide rail 411. The litter scooping body 422 is rotatably connected to the mounting base 421, and the litter scooping body 422 can swing in the first direction X when rotating. In use, the litter scooping body 422 directly scoops out the litter clumps in the litter trough 11. By designing the litter scooping body 422 as a rotatable floating design, even if the litter scooping body 422 encounters a large obstacle (such as another cat entering the litter trough 11 while the litter scooping body 422 is moving in the opposite direction of the first direction X) during its reset movement, the litter scooping body 422 can still move in the opposite direction of the first direction X. Figure 3 After urination or defecation occurs in the first space 111, a new mass of urine and feces is formed in the first space 111. The shovel body 422 can automatically swing in the first direction X under the reaction force of the obstruction, so that the shovel body 422 can easily cross the obstruction, thereby ensuring that the entire shovel cleaning assembly 4 can be reset to the initial position in the opposite direction of the first direction X, preventing the shovel cleaning assembly 4 from being stuck in the middle position.

[0049] Please refer to the following: Figures 1 to 3 and Figure 8The housing 1 includes an outer shell 13 and a sand chamber 14 disposed inside the outer shell 13. The sand chamber 14 contains the aforementioned sand trough 11. The sand chamber 14 is detachable longitudinally relative to the outer shell 13. By designing a detachable sand chamber 14, users can remove the sand chamber 14 separately to clean the internal sand trough 11, thereby facilitating the cleaning of the sand trough 11. To achieve the detachable function of the sand chamber 14, this solution designs the shovel component 42 to be slidably connected to the side of the movable seat 41 facing the collection chamber 2. Furthermore, a vertically penetrating mounting and disassembly groove 131 is provided on the inner side wall of the outer shell 13. Specifically, when the cleaning component 4 is reset to its initial position in the opposite direction of the first direction X, the movable seat 41 is located outside the upward movement path of the sand chamber 14, so that the movable seat 41 will not interfere with the upward removal of the sand chamber 14. At the same time, the end of the shovel component 42 in the length direction (i.e., the second direction Y) is located below the mounting and disassembly groove 131. In other words, when the sand bin 14 needs to be disassembled, the entire cleaning assembly 4 needs to be moved to the initial position in the opposite direction of the first direction X. Then, the shovel part 42 is taken out upward along the mounting and disassembly groove 131. Only then can the sand bin 14 be easily taken out upward. During the upward removal process, the sand bin 14 will collide with the drive part 201 of the bin door 200 to drive the bin door 200 to automatically open upward. Of course, the bin door 200 can also be manually opened upward before removing the sand bin 14.

[0050] Please refer to the following: Figure 7 and Figure 9The sand trough 11 has racks 9 fixed on both sides in the second direction Y. The length direction of the racks 9 extends in the first direction X. The aforementioned movable seat 41 preferably achieves a sliding connection with the housing 1 in the first direction X by directly sliding with the racks 9 in the first direction X. The aforementioned drive mechanism 3 is preferably designed to be housed within the movable seat 41 to save space occupied by the drive mechanism 3, thereby helping to reduce the overall size of the flat-push pet litter box. The drive mechanism 3 preferably includes a motor 31, a drive gear 32, a transmission gear 33, a transmission rod 34, and a travel gear 35. The motor 31 is fixedly connected to the movable seat 41, the transmission rod 34 is rotatably connected to the movable seat 41, and both ends of the transmission rod 34 extend beyond the movable seat 41 along the second direction Y. The transmission gear 33 is sleeved and fixed on the transmission rod 34. The drive gear 32 is connected to the motor 31 and meshes with the transmission gear 33. The travel gear 35 is sleeved and fixed at both ends of the transmission rod 34 in the length direction (i.e., the second direction Y). The travel gear 35 meshes with a corresponding rack 9. When motor 31 drives the drive gear 32 to rotate, the drive gear 32 will drive the transmission gear 33 to rotate. Since the transmission gear 33 and the transmission rod 34 are fixedly connected, the transmission rod 34 will rotate with the transmission gear 33, thereby causing the traveling gear 35 at the end of the transmission rod 34 to roll relative to the rack 9. This achieves the purpose of enabling the entire cleaning assembly 4 to move along the first direction X. In fact, by controlling the forward and reverse rotation of motor 31, the entire cleaning assembly 4 can be controlled to move in the positive or negative direction of the first direction X. In other embodiments, the drive mechanism 3 can also be a lead screw module or a linear motor.

[0051] Please refer to the following: Figure 1 , Figure 3 and Figure 9 Considering that cats usually bury the litter box manually after using it, and that litter may fall onto the rack 9 during the process, causing severe wear on the rack 9 as the traveling gear 35 rolls on it, this embodiment addresses this issue by providing flexible dustproof strips 10 on both sides of the opening of the litter trough 11 along the second direction Y. The dustproof strips 10 are designed inside the rack 9 to separate it from the litter trough 11. The upper or lower end of the dustproof strip 10 is fixedly connected to the housing 1. The aforementioned transmission rod 34 extends from the dustproof strip 10 to the top or bottom of the rack 9, allowing the traveling gear 35 at the end of the transmission rod 34 to mesh with the rack 9. This design prevents litter from splashing onto the rack 9 without affecting the movement of the entire litter cleaning assembly 4 in the first direction X. In other embodiments, a bellows cover can be used to simultaneously cover both the rack 9 and the traveling gear 35.

[0052] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
