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 enrichment also increase, leading to a rise in pet ownership (such as cats, rabbits, or dogs). Consequently, the demand for intelligent pet litter boxes for collecting feces and urine is also growing. Currently, there is a type of flat-push pet litter box. Taking cat litter as an example, this litter box is used in conjunction with cat litter as a toilet. Cat litter is pre-filled into the litter box, and the cat urinates or defecates in it. The feces and urine mix with the litter to form a litter clump. After the cat finishes and leaves, a cleaning component moves linearly under the drive of a mechanism, pushing the litter clump containing feces and urine into a collection chamber on one side, where it is collected. However, existing flat-push pet litter boxes lack odor control in the litter box and collection chamber, resulting in a poor user experience. Therefore, improvements to existing flat-push pet litter boxes are necessary.

[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

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A push-type pet litter box includes a shell, a waste collection chamber, a drive mechanism, a waste cleaning component, a chamber door, a first deodorizing box, and a second deodorizing box;

[0007] The housing has an upward-opening sand trough. The feces collection chamber is detachably connected to the housing. The feces collection chamber has a feces collection slot, which is located adjacent to the sand trough along a first direction. The feces cleaning component extends into the sand trough and is slidably connected to the housing along the first direction. The driving mechanism is connected to the housing and the feces cleaning component. The driving mechanism is used to drive the feces cleaning component to reciprocate linearly along the first direction so that the feces cleaning component can push the sand clumps in the sand trough into the feces collection slot. The chamber door is rotatably connected to the housing and is used to cover the opening of the feces collection slot. The first deodorizing box is detachably connected to the chamber door and is used to deodorize the feces collection chamber. The second deodorizing box is detachably connected to the side of the feces cleaning component facing the feces collection chamber and is used to deodorize the sand trough.

[0008] In one of the technical solutions, the top of the compartment door has an installation hole that extends downward into the collection trough. The first deodorizing box is housed in the installation hole from the top of the compartment door. Multiple side holes in the installation hole have protruding limiting protrusions to restrict the position of the first deodorizing box. The top surface of the compartment door has a notch that communicates with the installation hole.

[0009] In one of the technical solutions, the fecal cleaning component has an installation groove on the side facing the fecal collection chamber. The installation groove extends upward and has two protruding strips on the side wall of the installation groove. The two protruding strips extend longitudinally and are spaced apart to form a slide. The second deodorizing box slides longitudinally into the installation groove along the slide.

[0010] In one of the technical solutions, the feces-cleaning assembly includes a movable seat and a feces-shoveling component;

[0011] The movable seat is slidably connected to the housing along the first direction. The drive mechanism is connected to the movable seat.

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.

[0014] 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.

[0015] In one of the technical solutions, the housing includes an outer shell and a sand chamber placed inside the outer shell, the sand chamber being provided with the sand trough, and the sand chamber being longitudinally detachable relative to the outer shell;

[0016] The shovel component is slidably connected to the side of the movable seat facing the collection chamber. The inner sidewall of the outer shell is provided with a mounting and disassembly groove that runs through both the top and bottom. When the cleaning component is reset to its initial position in the opposite direction of the first direction, the movable seat is located outside the path of the sand chamber moving upward, and the end of the shovel component in the length direction is located below the mounting and disassembly groove.

[0017] In one of the technical solutions, the push-type pet litter box further includes a first sensor and a second sensor. During the movement of the litter box component within the litter box, the litter box is divided into a first space and a second space arranged adjacent to each other along the first direction. The first sensor and the second sensor are disposed on the housing or on the movable base. The first sensor is used to detect biometric information in the first space, and the second sensor is used to detect biometric information in the second space. Both the first sensor and the second sensor are signal-connected to the drive mechanism.

[0018] In one of the technical solutions, the compartment door has a rotational tendency to automatically cover the opening of the collection tank under its own weight.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] Please refer to the following: Figure 1 , Figures 3 to 5The sliding pet litter box of this embodiment also includes a door 200, a first deodorizing box 7, and a second deodorizing box 8. The door 200 is rotatably connected to the housing 1 and is used to cover the opening of the waste collection trough 21 to limit the outward diffusion of odorous gases inside the waste collection trough 2. The first deodorizing box 7 is detachably connected to the door 200 and is used to deodorize the waste collection trough 21. The second deodorizing box 8 is detachably connected to the side of the waste cleaning assembly 4 facing the waste collection trough 2 and is used to deodorize the litter box 11. Specifically, this solution includes a first deodorizing box 7 on the door 200 to deodorize the litter box 21, and a second deodorizing box 8 on the litter cleaning component 4 to deodorize the litter box 11. By setting the first deodorizing box 7 and the second deodorizing box 8, the odor released from the pet litter box during use can be reduced, thereby improving the user experience. In addition, both the first deodorizing box 7 and the second deodorizing box 8 can be disassembled independently, allowing users to refill them with new deodorizing agent themselves.

[0049] Please refer to the following: Figure 10 and Figure 11 The top of the compartment door 200 has a mounting hole 204 that extends downwards into the waste collection trough 21. The aforementioned first deodorizing box 7 is housed within this mounting hole 204 from the top of the compartment door 200. Multiple side holes within the mounting hole 204 have protruding limiting protrusions 202. When the first deodorizing box 7 is inserted into the mounting hole 204, the limiting protrusions 202 restrict the position of the first deodorizing box 7, preventing it from falling downwards when the compartment door 200 is opened upwards. Furthermore, the top surface of the compartment door 200 has a notch 203 that communicates with the mounting hole 204. This notch 203 allows the user's finger to be inserted, making it easier for the user to remove the first deodorizing box 7.

[0050] Please refer to the following: Figure 10 and Figure 12 The cleaning component 4 has an installation groove 412 on the side facing the collection chamber 2. The installation groove 412 extends upward and has two protruding strips 413 on the side wall of the installation groove 412. The two protruding strips 413 extend longitudinally and are spaced apart to form a slide 414. With this design, the second deodorizing box 8 can slide down longitudinally into the slide 414 and be housed in the installation groove 412. When the cleaning component 4 moves along the first direction X, the second deodorizing box 8 is restricted by the protruding strips 413 and will not fall out of the installation groove 412, ensuring that the second deodorizing box 8 can be firmly attached to the cleaning component 4.

[0051] Please see Figure 13The first deodorizing box 7 and the second deodorizing box 8 have the same structure, both including a bottom shell 71 and a top cover 72. The bottom shell 71 and the top cover 72 are detachably connected. By opening the top cover 72, new deodorizing agent can be filled into the bottom shell 71. The top cover 72 is provided with multiple through holes 73, allowing the fresh gas emitted from inside the deodorizing box to enter the sand trough 11 or the feces collection trough 21 through the through holes 73. In fact, after the first deodorizing box 7 is installed on the door 200, the through holes 73 on the first deodorizing box 7 need to face the bottom feces collection trough 21. After the second deodorizing box 8 is installed on the feces cleaning component 4, the through holes 73 on the second deodorizing box 8 need to face the first direction X.

[0052] Please refer to the following: Figure 3 , Figure 6 and Figure 7 The 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 the first direction X. The drive mechanism 3 is connected to the movable seat 41 and is used to drive the movable seat 41 to reciprocate along the straight line of the first direction X. The shovel component 42 extends into the sand trough 11 and is slidably connected to the movable seat 41 along the longitudinal direction. Preferably, the outer surface of the movable seat 41 is provided with a guide rail portion 411 extending longitudinally. The shovel component 42 slides down from this guide rail portion 411. The housing 1 is provided with guide grooves 12 on two opposite inner sides. The bottom end of the guide groove 12 extends to the path on which the shovel component 42 moves along the first direction X. The guide groove 12 extends upward at an incline toward the collection chamber 2. The bottom surface of the sand 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 extended in an arc shape. The mounting groove 412 is preferably provided on the side of the movable seat 41 facing the collection chamber 2. Specifically, after the cat finishes using the litter box 11, the litter-cleaning component 4, driven by the drive mechanism 3, moves to its end along the first direction X. The scooping component 42 then slides into the guide groove 12 and moves upwards under its guidance. Simultaneously, the scooping component 42 pushes the litter clump containing urine and feces upwards along the inclined surface 113 until it is pushed into the waste collection chamber 2 on one side. Through this design, the scooping component 42 essentially only pushes litter clumps containing urine and feces into the waste collection chamber 2, while normal litter without urine and feces is almost never pushed into it, thus reducing litter consumption. 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.

[0053] Please refer to the following: Figure 6 and Figure 7The shovel component 42 includes a mounting base 421 and a shovel body 422. The mounting base 421 and the aforementioned movable base 41 are slidably connected in the longitudinal direction through a connecting guide rail 411. The shovel body 422 is rotatably connected to the mounting base 421. Moreover, the shovel body 422 can swing in the first direction X when rotating. In use, the scoop body 422 directly removes the litter clumps in the litter trough 11. By designing the scoop body 422 as a rotatable floating design, when the scoop body 422 moves in the opposite direction of the first direction X to reset, even if the scoop body 422 encounters a large obstacle (for example, if another cat enters the litter trough 11 to urinate or defecate while the scoop body 422 is moving in the first direction X, causing a new litter clump containing urine and feces to form in the litter trough 11), the scoop body 422 can automatically swing in the first direction X under the reaction force of the obstacle, so that the scoop body 422 can easily overcome the obstacle, thereby ensuring that the entire litter cleaning assembly 4 can reset to the initial position in the opposite direction of the first direction X, preventing the litter cleaning assembly 4 from being stuck in the middle position.

[0054] Please refer to the following: Figure 3 and Figure 4 The push-type pet litter box in this embodiment also includes a first sensor 5 and a second sensor 6. During the movement of the 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 moving base 41. 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.

[0055] Please refer to them again. Figure 3 and Figure 4In 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 movable seat 41 facing the stool collection chamber 2. In other embodiments, the first sensor 5 and the second sensor 6 may both be fixed on the movable seat 41, or the first sensor 5 and the second sensor 6 may both be fixed inside the housing 1.

[0056] Please refer to the following: Figure 1 , Figures 3 to 5 In this embodiment, the compartment door 200 is designed to automatically cover the opening of the collection trough 21 under its own weight. A drive unit 201 protrudes from the compartment door 200. 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 compartment door 200 upwards by squeezing the drive unit 201, thereby opening the opening of the collection trough 21. When the cleaning component 4 moves away from the collection chamber 2 in the opposite direction of the first direction X, the compartment door 200 will automatically fall down due to gravity and cover the collection trough 21 again.

[0057] Please refer to the following: Figures 1 to 3 and Figure 8 The 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.

[0058] 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.

[0059] 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.

[0060] 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.
