Drive unit and pet toilet

Abstract

This invention relates to a driving device and a pet toilet. The driving device is used to drive a separating component to move within a litter box, separating pet litter clumps from the litter box. The driving device includes a driving arm and a driving power source. One end of the driving arm is rotatably connected to the separating component, and the other end of the driving arm is rotatably connected to the driving power source. One end of the driving arm can rotate around the driving power source, causing the other end to move between opposite ends of the litter box, thereby driving the separating component to separate pet litter clumps from the litter box. Furthermore, the driving power source can also drive the separating component to rise and move the raised separating component outside the litter box. The separating component outside the litter box can rotate relative to the driving arm, causing it to dump the separated pet litter clumps outside the litter box. Pet toilets using this driving device automatically clean without needing to flip the litter box; therefore, the side walls of the pet toilet are less likely to become contaminated with excrement.

Description

Technical Field

[0001] This invention relates to the field of pet toilet technology, and in particular to a drive device and a pet toilet. Background Technology

[0002] Pet owners typically provide their pets with dedicated litter boxes, such as cat litter boxes, to guide their cats to eliminate in a designated area. The litter in a cat litter box clumps together when the excrement is wet, making it easier to remove from the dry litter. Because pet excrement has an odor, pet owners need to remove the litter clumps promptly; otherwise, the cat will refuse to use the litter box.

[0003] Currently, the most common type of cat litter box with automatic cleaning function in the industry is the side-roller type. Its working principle involves the rotation of the litter bin, which drives the litter clumps through a filter screen, thus separating the litter from the litter clumps. However, because side-roller cat litter boxes require turning over the mixed litter clumps, excrement can easily stick to the inner wall of the litter box, leading to frequent cleaning of the inner wall. Summary of the Invention

[0004] Therefore, it is necessary to provide a driving device and a pet toilet to address the problem that excrement easily sticks to the inner wall of side-roller cat toilets. This driving device can drive the separating component to move inside the litter box and separate the pet litter clumps from the litter box. Pet toilets using this driving device can separate pet litter clumps from pet litter without turning the litter over.

[0005] A driving device, comprising:

[0006] A driving arm and a driving source component, wherein one end of the driving arm is rotatably connected to the separating component, and the other opposite end of the driving arm is rotatably connected to the driving source component;

[0007] One end of the driving arm can rotate around the driving force source, so that the other end moves between the two ends of the litter box, thereby driving the separating member to separate pet litter from the litter box. In addition, the driving force source can also drive the driving arm to rotate, so as to lift the separating member. The lifted separating member can move to the outside of the litter box. The separating member located outside the litter box can rotate relative to the driving arm, so that the separating member pours the separated pet litter out of the litter box.

[0008] The aforementioned drive device can move the separating component at opposite ends of the litter box, separating pet litter from litter clumps, thus automatically cleaning the pet toilet. Since this drive device eliminates the need to flip the litter box, the side walls are less likely to become soiled with excrement. Furthermore, because the drive device can lift the separating component to the outside of the litter box, it reduces the odor from spilled litter clumps flowing into the litter box and affecting the pet's excretion. Additionally, because the drive arm, drive source, and separating component are all rotatably connected, the separating component can move to any position within the litter box, offering high freedom of movement and adaptability to various usage scenarios. For example, when the pet is relieving itself, the separating component and drive arm can be moved above the litter box, not occupying the pet's space and minimizing their impact on excretion. When the pet toilet begins automatic litter clump cleaning, the separating component can clean all areas within the litter box, resulting in low litter clump residue and thorough cleaning.

[0009] A pet toilet, comprising:

[0010] A litter box is used to hold pet litter.

[0011] A separator for separating clumps of pet litter from the litter box;

Detailed Implementation

[0033] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] Reference Appendix Figure 1 This invention provides a pet toilet 10 with an automatic cleaning function, capable of separating pet litter and litter clumps within the toilet. The litter clumps refer to the clumps of litter formed by the pet's excrement and litter after defecation. It is worth noting that this pet toilet 10 can be used with cat litter boxes, rabbit litter boxes, dog litter boxes, etc., and its specific application to any particular pet is not limited to this application.

[0037] Reference Appendix Figure 2 The pet toilet 10 includes a litter box 100, a separating component 200, a collecting device 300, and a driving device 400. The litter box 100 holds pet litter, the separating component 200 separates clumps of litter from the litter box 100, the collecting device 300 holds clumps of litter, and the driving device 400 moves the separating component 200 between opposite ends of the litter box 100, thus separating the pet litter from clumps. The driving device 400 also transports the separated clumps of litter to the collecting device 300 outside the litter box 100 for collection, completing the cleaning of the litter box 100. It is worth noting that the driving device 400 can be manufactured and sold separately as an independent product or component. The separately manufactured and sold driving device 400 can be used in combination with other components of the pet toilet 10.

[0038] In one embodiment, the collection device 300 may only include a collection box with a collection opening 310 for receiving pet litter lumps separated by the separator 200. In other embodiments, the collection device 300 may also include a bag feeding mechanism and a sealing mechanism (not shown). The bag feeding mechanism can deliver garbage bags to the collection opening 310, and the garbage bags delivered to the collection opening 310 can be used to collect pet litter lumps separated by the separator 200. The sealing mechanism includes a fixed mounting bracket fixedly mounted on the collection opening 310, and the sealing mechanism can heat-seal the garbage bags passing through the collection opening 310 segment by segment, thereby making the tubular garbage bags into interconnected garbage bag packages, which are easy to take out and discard, and reduce odor. Alternatively, the collection device 300 may be a conduit with a crushing mechanism inside. After receiving pet litter lumps separated by the separator 200, the crushing mechanism can crush the pet litter lumps, and the conduit can guide the crushed pet litter lumps to the sewer of the household toilet. Alternatively, the pet toilet may not need to have a collection device 300. Instead, the pet toilet 10 can be placed next to the household toilet, and the drive device 400 can directly remove the pet litter separated by the separator 200 into the household toilet.

[0039] The litter box 100 may include an outer litter box 110 and an inner litter box 120. The inner litter box 120 is used to hold pet litter, and the pet defecates in the inner litter box 120. The inner litter box 120 and the collection device 300 are arranged opposite each other inside the outer litter box 110. By arranging the inner litter box 120 containing pet litter and the collection device 300 opposite each other inside the same outer litter box 110, when the pet toilet 10 needs to be moved, only the outer litter box 110 needs to be lifted, making it convenient for the user to move. It is worth noting that in this embodiment, the exterior of the litter box 100 refers to the exterior of the inner litter box 120 used to store pet litter, and the collection device 300 located in the outer litter box 120 is also considered to be outside the litter box 100. The inner litter box 120 can have an opening at the top for the pet to enter, or an opening at the side for the pet to enter (the outer litter box 110 has an opening at a corresponding position that matches the inner litter box 120). In addition, the inner litter box 120 can be separated from the outer litter box 110 by lifting it upwards, or by pulling it out from the side. After separation, the inner litter box 120 can be used alone or cleaned. It is worth noting that the above pet entry methods and inner litter box 120 separation methods can be combined arbitrarily. In other embodiments, the outer litter box 110 can be omitted, or the space inside the box can be divided into two relatively independent chambers by setting a partition inside the box, one chamber being the litter box 100 and the other chamber being the collection device 300.

[0040] Reference Appendix Figure 3 Appendix Figure 4The pet toilet 10 may also include a cover 500, which is rotatably mounted on top of the outer litter box 110. The cover 500 can close or open the inner litter box 120 and the collection device 300 on the outer litter box 110. In addition, the cover 500 can be quickly attached to and detached from the outer litter box 110. Specifically, the cover plate 500 includes a first end 510 and a second end 520. The first end 510 has mounting shafts 511 on opposite sides, and the outer sand basin 110 has connecting notches 111 and mounting holes 112 on opposite sides. The connecting notches 111 communicate with the mounting holes 112, allowing the mounting shafts 511 to enter and engage with the mounting holes 112 through the connecting notches 111, and also allowing the mounting shafts 511 to disengage from the mounting holes 112 through the connecting notches 111. The second end 520 has one of a locking block 521 and a locking groove 113 on the side facing the outer sand basin 110, and the other of the locking block 521 and locking groove 113 on the side facing the cover plate 500 (as shown in the attached diagram). Figure 4 As shown, the locking block 521 can engage with the locking groove 113, thereby completing the relative fixation of the second end 520 and the outer sand basin 110. In addition, a handle groove 522 can be provided on the side of the second end 520 facing away from the outer sand basin 110. The handle groove 522 facilitates the user to operate the cover plate 500 to rotate around the connection between the mounting shaft 511 and the mounting hole 112, thereby allowing the cover plate 500 to close or open the inner sand basin 120 and the collection device 300.

[0041] In one embodiment, the mounting shaft 511 is positioned along its length (see attached diagram). Figure 3 The thickness in the X direction is greater than the width in the mounting shaft 511 (see attached figure). Figure 3 The thickness of the mounting shaft 511 in the Y direction (in the image) is adapted to the thickness of the connecting notch 111 in the width direction. Adaptation means that the thickness of the mounting shaft 511 in the width direction is less than or equal to the opening size of the connecting notch 111. The mounting shaft 511 in the width direction can enter or exit the mounting hole 112 (as shown in the attached image) through the connecting notch 111. Figure 4 (As shown); the thickness of the mounting shaft 511 along its length is greater than the opening size of the connecting notch 111. The mounting shaft 511 cannot enter or exit the mounting hole 112 along its length through the connecting notch 111. However, the diameter of the mounting hole 112 is greater than or equal to the diameter along the length of the mounting shaft 511. Therefore, the mounting shaft 511 can rotate within the mounting hole 112 (as shown in the attached figure). Figure 3(As shown). In this embodiment, when the cover plate 500 and the outer sand basin 110 are disassembled or assembled, the mounting shaft 511 needs to be rotated to align the width direction with the connection notch 111. At this time, the mounting shaft 511 can quickly enter or disengage from the mounting hole 112. That is, the cover plate 500 needs to be rotated to a specific angle relative to the outer sand basin 110 before it can be disassembled or assembled. When the mounting shaft 511 enters the mounting hole 112, it rotates within the mounting hole 112 to align the length direction with the connection notch 111. At this time, the mounting shaft 511 is fixed within the mounting hole 112 (as shown in the attached figure). Figure 3 (As shown). In other embodiments, the outer sand basin 110 may only have a connection notch 111, the opening size of which is larger than the thickness of the mounting shaft 511 in any direction, that is, the mounting shaft 511 can freely enter or leave the connection notch 111.

[0042] Reference Appendix Figure 5 In one embodiment, a blocking plate 512 is provided on the side of the mounting shaft 511 away from the cover plate 500. The size of the blocking plate 512 is larger than that of the mounting hole 112. The blocking plate 512 can prevent the mounting shaft 511 from accidentally sliding from the mounting hole 112 into the sand basin 100, thereby enhancing the connection stability between the mounting shaft 511 and the mounting hole 112.

[0043] In one embodiment, the cover plate 500 is provided with a pet entry hole 530 facing the inner litter box 120, through which the pet can enter the inner litter box 120 to defecate. In addition, the cover plate 500 may also have a sand leakage hole 540 around the pet entry hole 530, so that when the pet jumps out of the inner litter box 120 onto the cover plate 500, the pet litter brought out can flow back to the inner litter box 120 or the collection device 300 through the sand leakage hole 540, thereby reducing the amount of pet litter brought out by the pet.

[0044] The separating element 200 can be configured as a rake body 220 with a plurality of sieve holes 210. When the rake body 220 passes over the mixture of pet litter and pet litter lumps, the pet litter can flow through the sieve holes 210 from one side of the rake body 220 to the other side, while the pet litter lumps, due to their relatively large size, cannot pass through the sieve holes 210 and are sifted to the same side of the rake body 220, thereby achieving the separation of pet litter lumps and pet litter. In other embodiments, the separating element 200 can also be configured as a mechanical claw (not shown), which can pick up pet litter lumps in the pet litter, thereby completing the separation of pet litter and pet litter lumps.

[0045] The following will describe in detail, with reference to the accompanying drawings, how the drive unit 400 drives the separator 200 to remove pet litter from the inner litter box 120 to the collection device 300.

[0046] Reference Appendix Figure 5The drive device 400 includes a drive arm 410 and a drive source component 420. One end of the drive arm 410 is rotatably connected to the separator 200, and the other opposite end of the drive arm 410 is rotatably connected to the drive source component 420. Preferably, the drive arm 410 is an L-shaped rod.

[0047] One end of the drive arm 410 can rotate around the drive source 420, so that the other opposite end moves between the opposite ends of the litter box 100, thereby driving the separator 300 to separate pet litter from the litter box 100. In addition, the drive source 420 can also drive the drive arm 410 to rotate, so as to lift the separator 200. The lifted separator 200 can move to the collection opening 310 located outside the litter box. The separator 200 located at the collection opening 310 can rotate relative to the drive arm 410, so that the separator 200 pours the separated pet litter into the collection device 300.

[0048] It is worth noting that, in order for the separating element 200 to completely separate pet litter and pet litter lumps, during the movement of the other opposite end of the driving arm 410 between the opposite ends of the litter box 100, the separating element 200 needs to be kept in contact with the bottom of the inner litter box 120. This contact is not absolute; for example, there may be a slight distance between the separating element 200 and the bottom of the inner litter box 120, but this does not affect the separating element 200's ability to separate all the pet litter and pet litter lumps, and can still be considered as contact. In addition, during the movement of the driving arm 410 between the opposite ends of the litter box 100, the separating element 200 can also move from one end of the inner litter box 120 along its length to the other opposite end, that is, the separating element 200 can separate pet litter at any position along the length of the inner litter box 120.

[0049] The drive arm 410 rotates relative to the drive source 420, enabling the pet toilet 10 to switch between a working state and a storage state. In the working state, the separating part 200 abuts against the bottom of the litter box 102; in the storage state, the drive arm 410 rotates around the drive source 420 until it is flush with the cover plate 500, and the separating part 200 rotates around the drive arm 410 until it is flush with the cover plate 500 (as shown in the attached diagram). Figure 6 As shown, the drive arm 410 and the separator 200 should be kept as far away from the inner litter box 120 as possible to prevent them from occupying the space for pet excretion and affecting pet excretion.

[0050] Reference Appendix Figure 7In one embodiment, the driving source 420 includes a housing 421 and a first driver 422. The first driver 422 is disposed in the housing 421, and its output end is connected to the driving arm 410, thereby driving the driving arm 410 to rotate. Specifically, the housing 421 has a mounting slot 4211 for mounting the first driver 422, and the mounting slot 4211 communicates with the outside of the housing 421. The first driver 422 is disposed in the mounting slot 4211, and the driving arm 410 is sleeved on the first driver 422, allowing the driving arm 410 to rotate within the mounting slot 4211. The first driver 422 includes a first motor 4221 and an adapter (not shown). The output end of the first motor 4221 is circumferentially fixed to one end of the adapter. The driving arm 410 has several circumferentially arranged fixing holes 411 facing the first motor 4221. The other end of the adapter is inserted into the fixing holes 411 of the driving arm 410 for fixation.

[0051] The movement of the other opposite end of the drive arm 410 between the opposite ends of the sand basin 100 can be such that the housing 421 can be translated above the sand basin 100, thereby driving the drive arm 410 mounted on the housing 421 to move. Specifically, the drive device 400 also includes a guide rail 430, which can be disposed on the side of the cover plate 500 facing the sand basin 100. The guide rail 430 and the cover plate 500 can be connected by a threaded connection, with threaded holes provided on the guide rail 430 and the cover plate 500, and the connection between the two achieved by a threaded connector; or, the guide rail 430 can be integrally formed and disposed on the cover plate 500. The housing 421 is movably disposed on the guide rail 430. The movability can be achieved by one of the guide rail 430 and the housing 421 having a moving groove 431, and the other of the guide rail 430 and the housing 421 having a moving block 4212, which can engage with the moving groove 431 and move within the moving groove 431; the housing 421 moves on the guide rail 430 to complete the movement of the drive arm 410 between the opposite ends of the sand basin 100. In other embodiments, the guide rail 430 can be disposed on the side wall of the sand basin 100.

[0052] The drive device 400 also includes a second driver 423, which drives the housing 421 to move on the guide rail 430. Specifically, the guide rail 430 may be provided with a plurality of slots 432 along its length. The second driver 423 is disposed on the housing 421 and includes a second motor 4231 and a gear 4232. The output end of the second motor 4231 is connected to the gear 4232. The gear 4232 can be exposed outside the housing 421 and mesh with the slots 432. The second motor 4231 can drive the gear 4232 to move along the length of the guide rail 430, thereby driving the housing 421 to move on the guide rail 430. In other embodiments, gear 4232 can be replaced with a rubber wheel (not shown). In this embodiment, the guide rail 430 may not have a groove 432, and the rubber wheel directly abuts against the guide rail 430. The output end of the second motor 4231 is connected to the rubber wheel, and the second motor 4231 can drive the rubber wheel to move on the guide rail 430, thereby driving the housing 421 to move on the guide rail 430. Alternatively, the second driver 423 may include a second motor 4231 and a lead screw (not shown). The output end of the second motor 4231 is connected to one end of the lead screw, and the other end of the lead screw is connected to the housing 421. The second motor 4231 can drive the lead screw to push the housing 421 to move on the guide rail 430. In this embodiment, the second driver 423 is disposed on the inner wall of the sand basin 100.

[0053] In one embodiment, at least one end of the guide rail 430 along its length has a notch 433, allowing the housing 421 to detach from the guide rail 430 through the notch 433. This allows components such as the drive arm 410 and the separator 200 associated with the housing 421 to detach from the guide rail 430. This design not only facilitates user replacement and maintenance of parts, but also allows the pet toilet 10 to be used independently after removing the drive unit 400 and the separator 200.

[0054] The other relative movement of the drive arm 410 between the opposite ends of the sand basin 100 can be achieved by fixing the housing 421 above the sand basin 100, and configuring the drive arm 410 to change its length as it rotates relative to the housing 421. Specifically, the drive arm 410 can be configured as a telescopic rod (as shown in the attached diagram). Figure 8As shown in the figure, the driving arm 410 includes a first rod 412 and a second rod 413. The first rod 412 has a telescopic cavity (not shown), and the second rod 413 is movably disposed in the telescopic cavity. The first rod 412 is rotatably connected to the housing 421, and the second rod 413 is rotatably connected to the separating member 200. When the separating member 200 moves between the opposite ends of the sand basin 100, the second rod 413 moves accordingly within the telescopic cavity to keep the separating member 200 abutting against the bottom of the sand basin 100. Alternatively, the driving arm 410 can also be configured as a folding rod (not shown). The driving arm includes a third rod and a fourth rod. The third rod can rotate relative to the fourth rod so that the third rod is stacked on top of the fourth rod. The third rod is rotatably connected to the housing 421, and the fourth rod is rotatably connected to the separating member 200. When the separating member 200 moves between the opposite ends of the sand basin 100, the third rod and the fourth rod rotate accordingly to keep the separating member 200 abutting against the bottom of the sand basin 100. It is worth noting that in embodiments where the drive arm 420 is a folding rod or a telescopic rod, the drive arm 410 can be rotated relative to the housing 421 by providing a driver inside the drive arm 410, and the first driver 421 may not be provided inside the housing 421.

[0055] Reference Appendix Figure 9 In one embodiment, the driving device 400 further includes a third driver 440, which is mounted on the driving arm 410. The output end of the third driver 440 is connected to the separator 200, and the third driver 440 can drive the separator 200 to rotate relative to the driving arm 410. Specifically, the third driver 440 includes a sleeve 441 and a third motor 442. The sleeve 441 is sleeved on the output end of the third motor 442, and the sleeve 441 and the output end of the third motor 442 are circumferentially fixed. The circumferentially fixed connection method can be that the output end of the third motor 442 is provided with a hexagonal bushing 443, and the sleeve 441 has a hexagonal locking hole 4411 facing the third motor 442 (as shown in the attached figure). Figure 10 As shown), one end of the hexagonal bushing 443 is connected to the output end of the third motor 442, and the other end is engaged in the hexagonal locking hole 4411; the sleeve 441 is fixedly connected to the separator 200. The fixed connection method can be that the sleeve 441 and the separator 200 are provided with corresponding threaded holes, and the connection is relatively fixed through the threaded connector.

[0056] In one embodiment, the housing 421 may also be equipped with sensors (such as one or more of infrared sensors, photoelectric sensors, laser sensors, ultrasonic radar, millimeter-wave radar, etc.) to detect the pet's entry and exit from the pet toilet 10 and its defecation.

[0057] In one embodiment, the pet toilet 10 can also have a disinfection function, capable of disinfecting and sterilizing the pet litter in the litter box 100. Specifically, the pet toilet 100 can achieve the disinfection function by setting an ultraviolet disinfection lamp, which is located above the litter box 100. For example, the ultraviolet disinfection lamp can be located on the cover plate 500 directly above the litter box 100, or it can be located on the side wall above the litter box 100, and the pet litter is disinfected and sterilized by the ultraviolet disinfection lamp. In other embodiments, the pet toilet 10 can also use an automatic spray mechanism to spray disinfectant to disinfect and sterilize the pet litter. In addition, the pet device 10 can also have an odor disinfection function to remove odors from the litter box 100 and prevent excessive odors from affecting the pet's excretion. Specifically, activated carbon can be placed in the litter box 100 to absorb odors, and air freshener can also be sprayed into the litter box 100 to remove odors.

[0058] The pet toilet 10 using the aforementioned driving device allows the separating member 200 to move between opposite ends of the litter box 100 via the driving device 400, separating pet litter and litter clumps within the litter box 100. This achieves automatic cleaning of the pet toilet 10. Since automatic cleaning of the pet toilet 10 does not require flipping the litter box, the side walls of the pet toilet 10 are less likely to become contaminated with excrement. Furthermore, because the pet toilet 10 uses a lifting mechanism to raise the separating member 200 to the collection opening 310 of the collection device 300, the height of the collection device 310 can be set higher than the litter box 100. This not only increases the capacity of the collection device 310 but also reduces the flow of odors from the collection device 310 into the litter box 100, thus minimizing their impact on pet excretion. Furthermore, since the drive arm 410, drive source component 420, and separator 200 are all rotatably connected, the separator 200 can move to any position within the litter box 100, exhibiting high overall freedom of movement and adaptability to various usage scenarios. For example, when a pet is defecating, the separator 200 and drive arm 410 can be moved above the litter box 100, without occupying the pet's space within the litter box 100, thus reducing the impact of the separator 200 and drive arm 410 on the pet's excretion. When the pet toilet 10 begins automatically cleaning pet litter, the separator 200 can clean various locations within the litter box 100, resulting in a low probability of pet litter residue and thorough cleaning. After removing pet litter from the litter box 100, the drive device 400 can also drive the separator 200 to reciprocate within the litter box 100, thereby leveling the pet litter within the litter box 100 and preventing pet litter from accumulating in specific locations, which could affect the pet's excretion.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
