[0047] The pet device in this embodiment can be used as a pet toilet, specifically including a frame and a cleaning mechanism. The frame includes a first cavity 1, a second cavity 2, and a partition separating the first cavity 1 and the second cavity 2, all arranged adjacent to each other. Pet litter (e.g., cat litter) can be added to the first cavity 1, while the second cavity 2 is mainly used to collect waste cat litter. In this embodiment, the second cavity 2 is located at the front of the first cavity 1, and the partition is either part of the first cavity 1 or part of the second cavity 2. More specifically, the partition can be part of the front side of the first cavity 1 or part of the rear side of the second cavity 2. The partition can be detachably connected to the first cavity 2, or the partition can be detachably connected to the second cavity 2, to facilitate adding pet litter to the first cavity 1 or cleaning waste pet litter from the second cavity 2.

[0048] The cleaning mechanism includes a cleaning frame 4 that moves within the first cavity 1 in a direction approaching or away from the second cavity 2, a drive mechanism for moving the cleaning frame 4, and a scraper 3 mounted on the cleaning frame 4 and moving synchronously with it. The scraper 3 can move up and down along the cleaning frame 4. When the cleaning frame 4 moves towards the second cavity 2, the scraper 3 can move upward to allow items in the first cavity 1 (such as clumps of waste cat litter) to cross the partition and enter the second cavity 2.

[0049] In this embodiment, the cleaning rack 4 is configured to drive the scraper 3 to move along the front-to-back direction of the pet equipment, and the scraper 3 can slide up and down relative to the cleaning rack 4. In some other embodiments, the scraper 3 can also rotate while sliding up and down relative to the cleaning rack; the specific movement of the scraper 3 is not limited here.

[0050] The scraper 3 has at least a first position farther from the second cavity 2 and a second position closer to the second cavity 2. When the scraper 3 is in the first position, at least the bottom of the scraper 3 is lower than the top of the partition, and there is a gap between the scraper 3 and the second cavity 2. When the scraper 3 is in the second position, at least a portion of the scraper 3 is higher than the partition and the scraper is close to the second cavity 2, and the scraper 3 is in contact with the second cavity 2. That is, the height of the scraper 3 in the second position is higher than the height in the first position. In this embodiment, the scraper 3 always extends vertically, and the scraper 3 has a gap that is larger than the particle size of clean pet litter but smaller than the size of the clumped waste pet litter. For example, the scraper 3 can be configured as a mesh or comb structure. Furthermore, the lower edge of the scraper 3 can also have a short upward-curved section, which provides some support for the waste pet litter while ensuring that the waste pet litter can smoothly enter the second cavity 2.

[0051] like Figure 1 and Figure 2 As shown, the pet equipment also includes a drive mechanism located at the bottom. The drive mechanism is connected to the cleaning rack 4. Located at the bottom of the rack, the drive mechanism makes full use of the space below the first cavity 1, minimizing the overall size of the pet equipment. The drive mechanism includes a moving part, and the cleaning rack 4 is connected to the moving part. Further, the drive mechanism includes a transmission screw 51, a nut 52 (i.e., the moving part), and a drive motor 53. The transmission screw 51 is located below the first cavity 1 and extends along the front-rear direction of the pet equipment. The nut 52 is fixedly connected to the cleaning rack 4 and is screwed to the transmission screw 51. See details... Figure 1 and Figure 5 Nut 52 is sleeved on transmission screw 51. Drive motor 53 is used to drive transmission screw 51 to rotate. In some other embodiments, the drive mechanism may include gears and racks, or it may include a drive cylinder. This embodiment does not limit the structure and specifications of the drive mechanism; it can be set according to actual needs.

[0052] like Figure 2 As shown, the drive motor 53 is also electrically connected to an external power supply 54. In this embodiment, the power supply 54 is independent of the pet device. In some other embodiments, the power supply may also be located inside the pet device. This is not limited here.

[0053] like Figure 3 As shown, the first cavity 1 has a connecting guide surface 11 and a lower bottom surface 12. The guide surface 11 is located on the side near the second cavity 2, specifically, the guide surface 11 is located on the front side of the lower bottom surface 12. When the scraper 3 is in the second position, at least part of the scraper 3 and the guide surface 11 are in close contact. The guide surface 11 can be an inclined surface, an arc surface, or a combination of an inclined surface and an arc surface. In this embodiment, the guide surface 11 is an arc surface that protrudes outward from the inside of the first cavity 1 (specifically, protrudes towards the location of the transmission screw 51). The lower bottom surface 12 is parallel to the horizontal plane. The guide surface 11 is set as an arc surface so that when the cleaning rack 4 moves the scraper 3 to a position near the second cavity 2, the scraper 3 moves against the guide surface 11 until the scraper 3 moves to the top of the entire pet equipment, pushing the waste pet litter into the second cavity 2. In some other embodiments, the guide surface may not be provided, and instead a drive mechanism that drives the scraper 3 to move up and down along the cleaning rack 4 may be provided directly.

[0054] In this embodiment, the length of the transmission screw 51 is greater than or equal to the length of the first cavity 1 in the front-to-back direction. During the movement of the cleaning frame 4 and the scraper 3, once the scraper 3 contacts the guide surface 11, if the cleaning frame 4 continues to move forward, the guide surface 11 will block the scraper 3's forward movement. Therefore, the scraper 3 will gradually move upward relative to the cleaning frame 4 during the compression process with the curved surface. Thus, it is necessary to ensure that the cleaning frame 4 can move forward a sufficient distance to ensure that the scraper 3 can move upward a sufficient height, thereby allowing the scraper 3 to push a sufficient amount of waste pet litter into the second cavity 2 to ensure a good cleaning effect. Figure 3 and Figure 5 As shown, the pet equipment also includes a main body shell 6 fitted around the first cavity 1 and the second cavity 3, and a cleaning rack 4 disposed between the first cavity 1 and the main body shell 6. Figure 3 and Figure 5 As shown, since the scraper 3 always moves inside the first cavity 1, while the cleaning rack 4 moves around the first cavity 1, in order to ensure the connection between the scraper 3 and the cleaning rack 4, the height of the cleaning rack 4 and the scraper 3 is greater than the height of the first cavity 1.

[0055] The cleaning rack 4 includes at least a vertical section extending in a vertical direction, and the scraper 3 is slidably disposed on the vertical section. Further, the cleaning rack 4 specifically includes a first transmission part 41 and a second transmission part 42 disposed on opposite sides of the first cavity 1. The first transmission part 41 has a first segment 411 extending in a vertical direction, and the second transmission part 42 has a third segment 421 extending in a vertical direction. The upper ends of the first segment 411 and the third segment 421 are respectively provided with grooves extending in a vertical direction, and the scraper 3 is provided with protrusions that cooperate with the grooves, thereby slidably inserting into the grooves. In some other embodiments, grooves may also be provided on the scraper 3, and protrusions that cooperate with the grooves may be provided on the first segment 411 and the third segment 421. Figure 5 and Figure 8 As shown, the first transmission part 41 further includes a second segment 412 connected to the first segment 411 and extending in the left-right direction, and the second transmission part 42 further includes a fourth segment 422 connected to the third segment 421 and extending in the left-right direction. The first transmission part 41 and the second transmission part 42 are respectively L-shaped and arranged along the outer wall of the first cavity 1, and the second segment 412 and the fourth segment 422 are respectively fixedly connected to the nut 52. Figure 4 As shown, the chute in this embodiment is specifically a "T" shaped chute. In other embodiments, the chute can also be of other shapes, as long as it can enable the relative sliding of the cleaning rack 4 and the scraper 3.

[0056] In some other embodiments, the second segment 412 and the fourth segment 422 can also be integrally formed, that is, the first segment 411 and the third segment 421 are connected by a support crossbar, and the first transmission part 41 and the second transmission part 42 are a whole, in the shape of a "U", with the nut 52 fixedly connected to the support crossbar. Furthermore, a drive mechanism can be provided below the first transmission part 41 and the second transmission part 42 respectively. In this embodiment, it is preferred to provide a single drive mechanism, which makes it easier to keep the first transmission part 41 and the second transmission part 42 synchronized.

[0057] like Figure 1 As shown, the frame also includes a base plate 71 disposed below the first cavity 1 and the second cavity 2, and the two ends of the transmission screw 51 are respectively connected to the support base 72 fixed to the base plate 71. In this embodiment, it is preferable that the distance between the transmission screw 51 and the first segment 411 and the distance between the transmission screw 51 and the third segment 421 are equal, that is, the area of ​​the scraper 3 on the left and right sides of the transmission screw 51 is equal. This arrangement makes it easier to maintain balance during the movement of the cleaning frame 4 and the scraper 3.

[0058] The second cavity 2 includes an inner cavity 21 and a cover plate 22 rotatably connected to the inner cavity 21. The cover plate 22 effectively isolates odors from the second cavity 2. When the scraper 3 is in the first position, the orthographic projection of part of the cover plate 22 in a top view coincides with the orthographic projection of part of the guide surface 11. That is, before the scraper 3 contacts the cover plate 22 and when the cover plate 22 is still closed, a portion of the rear side of the cover plate 22 covers a portion of the front side of the first cavity 1. This arrangement facilitates the scraper 3 to open the cover plate 22 and push the waste pet litter into the inner cavity 21 during its upward movement. Furthermore, at least part of the second cavity 2 is detachably connected to the first cavity 1 or the main shell 6. For example, the bottom plate or side plate of the second cavity 2 is configured to be detachable, or the second cavity 2 can be completely detached to facilitate the user's cleaning of waste pet litter. The second cavity 2 can also be provided with a gripping part for easy disassembly.

[0059] A splash guard 8 is also provided above the main body shell 6. The splash guard 8 has an opening on its front side, and in this example, the splash guard 8 also has an opening on its upper side. The splash guard 8 is mainly used to prevent pet litter from falling out of the pet equipment from the left and right sides during the pet equipment's use and during automatic cleaning. The front opening of the splash guard 8 is to provide sufficient space for the rotation of the cover plate 22, and the upper opening of the splash guard 8 is to provide sufficient space for the upward movement of the scraper 3. In some other embodiments, after designing the upward movement distance of the scraper 3 and the height of the splash guard, the splash guard can also be set as a closed structure; the specific design is not limited here.

[0060] The following combination Figures 3 to 8 The operation process of the pet device in this embodiment will be described in detail:

[0061] When cleaning of the pet equipment is required, the drive motor 53 drives the transmission screw 51 to rotate, causing the cleaning rack 4 to move the scraper 3 from back to front. When the scraper 3 contacts the guide surface 11, the cleaning rack 4 continues to move forward. The guide surface 11 blocks the forward movement of the scraper 3, so the scraper 3 gradually moves upward relative to the cleaning rack 4 during the process of being squeezed against the curved surface. The scraper 3 pushes open the cover plate 22 of the second cavity 2 and pushes the waste pet litter into the second cavity 2, completing the cleaning. After cleaning is completed, the drive motor 53 reverses, and the cleaning rack 4 returns to the starting state from front to back, waiting for the next cleaning.

[0062] In summary, the pet device in this embodiment has at least the following advantages:

[0063] 1. The cleaning frame is driven by a drive mechanism, which in turn drives the scraper to move, enabling automatic cleaning of waste pet litter, making it highly convenient to use;

[0064] 2. The scraper can be movably mounted on the cleaning rack in the up-down direction, eliminating the need for additional grooves on the pet equipment to follow the scraper's movement path, resulting in a simple structure;

[0065] 3. The drive mechanism is located at the bottom of the pet device and has a simple structure and small size, which saves manufacturing costs.
