Description

Technical Field

[0001] The embodiments of this utility model belong to the field of pet supplies, and specifically relate to a pet litter box body, base, sealing element, and pet litter box. Background Technology

[0002] As people's material living standards continue to improve, their demands for spiritual life are also gradually increasing, leading to a growing number of people who enjoy keeping pet cats and dogs. Many cat and dog lovers adore their pets and have even purchased dedicated pet cabins for them. Most existing cat litter boxes are now smart litter boxes, which have greatly simplified the lives of cat owners, allowing them to pet their cats without having to clean up litter.

[0003] In existing technologies, to prevent the odor of pet excrement from overflowing from the collection container of a litter box, a mechanical transmission structure is usually used to seal the waste discharge port on the base of the litter box that connects to the collection container. Although this method can effectively prevent odor from overflowing, setting up a complex mechanical transmission structure on a compact litter box not only increases the difficulty of the litter box's structural design but also increases the product's production cost. Utility Model Content

[0004] The purpose of this utility model is to design a pet litter box body, base, sealing component, and pet litter box, which can not only seal the waste discharge outlet to prevent the odor generated in the waste collection device from overflowing into the external environment, but also simplify the structure of the pet litter box and reduce the design difficulty and production cost of the pet litter box.

[0005] To achieve the above objectives, an embodiment of the present invention provides a pet litter box body, wherein the body is at least partially disposed within the receiving space of the pet litter box base and is rotatable about a preset axis.

[0006] The basin is used to close the waste discharge port on the base when it is flipped to the initial position, and to flexibly seal the inlet side of the waste discharge port.

[0007] In addition, some embodiments of this utility model also provide a base for a pet litter box, the base having a accommodating space for mounting the basin as described above, and a waste discharge port communicating with the accommodating space;

[0008] The waste discharge outlet has an inlet side and an outlet side opposite to the inlet side; the inlet side is used to be closed by the basin when the basin is flipped to the initial position and to flexibly seal with the basin.

[0009] In addition, some embodiments of this utility model also provide a sealing element for a pet litter box. The sealing element is disposed between the basin body and the base as described above, and is used to flexibly seal the inlet side of the waste discharge port of the base to the basin body when the basin body is flipped to the initial position around a preset axis.

[0010] In addition, some embodiments of this utility model also provide a pet litter box, including:

[0011] The base as described above;

[0012] The basin as described above is at least partially embedded within the receiving space of the base;

[0013] The seal as described above.

[0014] Compared with the prior art, the embodiments of this utility model allow the litter box to be flipped back to its initial position after the litter box has finished emptying excrement and / or waste. This allows the litter box to seal the waste discharge port on the base and achieve a flexible seal with the inlet side of the waste discharge port. This not only isolates the waste discharge port from the outside world and effectively prevents odors generated in the litter box from overflowing into the external environment, but also simplifies the structure of the pet litter box and reduces the design difficulty and production cost of the pet litter box.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0026] Example 1

[0027] The first embodiment of this utility model relates to the body of a pet litter box, such as... Figure 1 As shown, the basin 1 is at least partially disposed within the accommodating space 22 of the base 2 of the pet litter box, and the basin 1 can be rotated around a preset axis.

[0028] The basin 1 is used to close the waste discharge port 21 on the base 2 when it is flipped to the initial position, and to flexibly seal the inlet side 211 of the waste discharge port 21.

[0029] As can be seen from the above, after the litter box 1 has finished emptying excrement and / or waste, it can be flipped back to its initial position, so that the litter box 1 can seal the waste discharge port 21 on the base 2 and achieve a flexible seal with the inlet side 211 of the waste discharge port 21. This not only isolates the waste discharge port 21 from the outside world and effectively prevents the odor generated in the litter box 6 from overflowing into the outside environment, but also simplifies the structure of the pet litter box and reduces the design difficulty and production cost of the pet litter box.

[0030] Specifically, in some embodiments, since the opening 11 of the basin 1 is generally facing the pet when the pet enters the basin 1, the initial position is the position when the basin 1 is stationary for a long time waiting for the pet to enter, and the position when the pet enters the basin 1 to relieve itself. Therefore, when the basin 1 is flipped back to the initial position, a flexible seal can be maintained between the basin 1 and the inlet side 211 of the waste discharge port 21 of the base 2 for a long time, effectively preventing odors from the toilet 6 from escaping into the external environment. Additionally, as... Figure 3 and Figure 4As shown, a sealing element 3 is provided between the basin body 1 and the inlet side 211 of the waste discharge port 21. For example, the sealing element 3 can be detachably installed on the basin body 1. This sealing element 3 allows for a flexible seal between the bottom 13 of the basin body 1 and the inlet side 211 of the waste discharge port 21 when the basin body 1 is flipped to its initial position. Specifically, when the basin body 1 is flipped to its initial position, the sealing element 3 can fit against the outer circumferential surface of the inlet side 211 of the waste discharge port 21, thus achieving a flexible seal between the basin body 1 and the inlet side 211 of the waste discharge port 21. Alternatively, in other embodiments, the sealing element 3 can also be partially inserted into the waste discharge port 21 when the basin body 1 is flipped to its initial position, and can be press-fitted with the waste discharge port 21. In this way, a flexible seal can also be achieved between the basin body 1 and the inlet side 211 of the waste discharge port 21.

[0031] Additionally, it is worth mentioning that in some embodiments, such as Figure 1 and Figure 3 As shown, the basin 1 includes: an upper edge 12 forming a basin opening 11, a basin bottom 13 relative to the upper edge 12, and the side of the basin 1 away from the basin opening 11 is a first spherical surface. Alternatively, combined with... Figure 1 and Figure 4 As shown, the side of the basin 1 away from the rim 11 is a first arc surface 131, and the first arc surface 131 extends along the flipping direction of the basin 1, so that the vertical distance from any point on the first arc surface 131 to the preset axis is equal, thereby ensuring that the basin 1 has a large flipping angle within the accommodating space 22 of the base 2. However, as a preferred solution, such as Figure 1 As shown, the first arc surface 131 extends along the tilting direction of the basin 1 to the rim 11 of the basin 1, making the entire basin 1 approximately bowl-shaped. This further increases the tilting angle of the basin 1, ensuring that the basin 1 can smoothly empty the collected waste and / or excrement when tilted. Furthermore, in some other embodiments, through... Figure 1 It is not difficult to see that, since the waste discharge port 21 is located on the bottom 23 of the base 2, and combined with Figure 9 As shown, the bottom 23 of the base 2 has a second arc surface 231 on the side facing the accommodating space 22. At the same time, the first arc surface 131 and the second arc surface 231 on the side of the basin bottom 13 away from the basin opening 1 have the same curvature, so that the gap between the basin 1 and the base 2 is small during the flipping process, thus preventing the pet from being pinched by the basin 1 when the basin 1 is flipped.

[0032] Furthermore, in order to ensure the sealing performance of the seal 3 when it is at the inlet side 211 of the flexible seal sewage discharge port 21, in some embodiments, such as Figure 3As shown, the sealing element 3 includes a mounting part 31 and a flexible sealing part 32. The mounting part 31 has approximately the same shape and size as the waste discharge port 21, and is detachably mounted on the basin 1. The flexible sealing part 32 is also connected to the mounting part 31. The orthographic projection of the flexible sealing part 32 onto the base 2 is a ring-shaped structure that surrounds the circumference of the waste discharge port 21. Therefore, when the basin 1 is flipped to its initial position, as... Figure 1 and Figure 2 As shown, the flexible sealing part 32 can fit against the outer peripheral surface 232 of the inlet side 211 forming the waste discharge port 21. Through the fit between the flexible sealing part 32 and the outer peripheral surface 232, a flexible seal can be achieved between the basin body 1 and the inlet side 211 of the waste discharge port 21. Alternatively, when the basin body 1 is flipped to the initial position, the flexible sealing part 32 can also be inserted into the waste discharge port 21 and press-fitted against it. In this way, a flexible seal can also be achieved between the basin body 1 and the inlet side 211 of the waste discharge port 21. Furthermore, in order to facilitate the installation of the sealing member 3 to the basin bottom 13 while ensuring the sealing performance between the basin body 1 and the inlet side 211 of the waste discharge port 21, in some embodiments, combined with... Figure 3 and Figure 4 As shown, the mounting part 31 can be a rigid mounting part, such as an injection-molded part or a metal part, so that the rigid mounting part 31 can be locked to the bottom of the basin 13 by bolts (not shown in the figure). The flexible sealing part 32 can be a rubber part, which can achieve a flexible seal between the basin 1 and the inlet side 211 of the waste discharge port 21 when the basin 1 is flipped to the initial position. It should be noted that, in order to make the sealing part 3 stably installed on the bottom 13 of the basin 1, as a preferred solution, in some other embodiments, such as Figure 2 As shown, a mounting groove 14 is provided on the side of the basin bottom 13 away from the basin opening 11, so that the mounting part 31 of the sealing member 3 can be directly embedded in the mounting groove 14. The mounting groove 14 can be used to position the sealing member 3 on the basin bottom 13. After the mounting part 31 of the sealing member 3 is installed in the mounting groove 14, the flexible sealing part 32 can protrude out of the mounting groove 14 to flexibly seal the inlet side 211 of the sewage discharge port 21. In addition, as a preferred embodiment, in some other embodiments, such as Figure 2As shown, at least a portion of the flexible sealing part 32 is exposed outside the mounting groove 14, and the flexible sealing part 32 includes: a first sealing section 321, a second sealing section 322 disposed relative to the first sealing section 321, and a connecting section 323 connected to the first sealing section 321 and the second sealing section 322 respectively. The connecting section 323 can fit against the mounting part 31 and can be locked to the bottom 13 of the basin body 1 by means of bolts. The first sealing section 321 and the second sealing section 322 can protrude from the mounting groove 14, and an annular groove (not shown in the figure) is formed between the first sealing section 321 and the second sealing section 322, into which a bolt can be screwed. Simultaneously, the first sealing section 321 and the second sealing section 322 can achieve a double-layer seal on the inlet side 211 of the waste discharge port 21 when the basin body 1 is flipped to the initial position, thereby further improving the sealing performance of the inlet side 211 of the waste discharge port 21.

[0033] However, as an alternative, in some other embodiments, such as Figure 1 As shown, Figure 5 , Figure 6 and Figure 7 As shown, a clamping element 4 is also provided on the basin body 1, and the sealing element 3 is detachably installed on the basin body 1 via the clamping element 4. Specifically, as Figure 6 As shown, the flexible sealing part 32 is located on one side of the mounting part 31. Simultaneously, the clamping member 4 can be used to clamp the mounting part 31 of the sealing member 3 from the side opposite to the bottom of the mounting groove 14. The clamping member 4 is separated from one side of the groove wall of the mounting groove 14, forming a notch 141. This notch 141 is for the flexible sealing part 32 to pass through, allowing a portion of the flexible sealing part 32 to be exposed outside the mounting groove 14. This allows it to abut against the inlet side 211 of the waste discharge port 21 on the base 2 when the basin 1 is flipped to its initial position, thus flexibly sealing the basin 1 against the inlet side 211 of the waste discharge port 21. Furthermore, through... Figure 5 It is easy to see that the mounting groove 14 is provided with a plurality of locking holes 15 along its circumference, and corresponding to each opening 15, the clamping member 4 is provided with a plurality of buckles 41 along its circumference. Each buckle 41 is used so that after the clamping member 4 is embedded in the mounting groove 14, it can be respectively locked into the corresponding locking hole 15, so that the clamping member 4 can be engaged with the groove wall of the mounting groove 14, thereby ensuring that the mounting part 31 of the sealing member 3 can be pressed tightly into the mounting groove 14 by the clamping member 4. At the same time, as a preferred solution, in some other embodiments, such as Figure 5 and Figure 6As shown, the mounting groove 14 is formed by a portion of the bottom 13 of the basin 1 protruding into the interior of the basin 1, so that a boss 16 can be formed inside the basin 1. The boss 16 can be locked and fixed to the clamping member 4 by bolts, screws and other locking devices (not shown in the figure). This not only further improves the clamping performance of the clamping member 4 on the sealing member 3, but also, by means of the engagement between the clamping member 4 and the groove wall of the mounting groove 14, when the clamping member 4 is locked and fixed to the boss 16 by bolts, screws and other locking devices, the clamping member 4 can also be pre-positioned in the mounting groove 14, avoiding the clamping member 4 from shifting when locking with the boss 16. This effectively improves the ease of installation between the clamping member 4 and the basin 1.

[0034] Additionally, as an alternative, in some other embodiments, such as Figure 8 As shown, the clamping component 4 includes an annular pressure strip 41, multiple pressure seats 42 disposed on the annular pressure strip 41, and connecting rods (not shown in the figure) disposed on each pressure seat 42. Each pressure seat 42 is distributed circumferentially along the annular pressure strip 41 and corresponds to each connecting rod, as shown in the figure. Figure 5 As shown, the basin body 1 is also provided with multiple mounting holes 17, and, as Figure 8 As shown, the sealing element 3 has multiple through holes 33, each corresponding to and connected to the mounting hole 17. Additionally, corresponding to each through hole 33 and mounting hole 17, each pressure seat 42 is provided with a positioning hole (not shown in the figure), and each positioning hole is aligned with each through hole 33 and positioning hole. Therefore, when the clamping element 4 presses the sealing element 3 onto the basin 1, combined with… Figure 8 As shown, each connecting rod can pass through each positioning hole into each through hole 33 and each mounting hole 17. Furthermore, it is worth noting that in some embodiments, each mounting hole 17 can be a threaded hole, and each connecting rod can be a bolt, which is threaded into each mounting hole 17. Therefore, by threading each connecting rod into each mounting hole 17, each bolt can apply force to each pressure seat 42, and the force can be transmitted to the annular pressure strip 41. This ensures that the annular pressure strip 41 can press and fix the sealing element 3 to the basin 1 as a whole under the action of each pressure seat 42, thus realizing the installation of the sealing element 3 on the basin 1.

[0035] Furthermore, since the basin 1 may have some play during the flipping process, it is necessary to ensure the sealing performance between the basin 1 and the inlet side 211 of the waste discharge port 21 when the basin 1 is flipped to the initial position. As a preferred embodiment, in some other embodiments, the length of the flexible sealing part 32 of the sealing member 3 can be appropriately lengthened, so that when the basin 1 is flipped to the initial position relative to the base 2, the basin 1 has an allowable angular accuracy in the initial position, so that the basin 1 can achieve a flexible seal with the inlet side 211 of the waste discharge port through the sealing member 3 within the angular accuracy range. For example, in some embodiments, the angular accuracy of the basin 1 can be controlled between +10° and -10°. If the default angle of the basin 1 in the initial position is 0°, and the basin 1 is actually flipped to between +10° and -10°, a flexible seal can be achieved between the basin 1 and the inlet side 211 of the waste discharge port 21 through the sealing member 3.

[0036] Additionally, in other embodiments, such as Figure 10 As shown, a sand-blocking plate 5 is also provided on the basin body 1, and the sand-blocking plate 5 is arranged circumferentially along part of the basin opening 11. By providing the sand-blocking plate 5 on the basin body 1, when the pet leaves the basin body 1 from the basin opening 11, the sand-blocking plate 5 can partially or completely remove the fine sand adhering to the pet's fur, allowing the removed fine sand to remain inside the basin body 1. This can reduce the amount of fine sand brought out by the pet when leaving the basin, effectively reducing pollution to the indoor environment. Furthermore, it should be noted that in some embodiments, the sand-blocking plate 5 can be a crescent-shaped sand-blocking plate with a higher middle and lower ends. It is easy to see that the higher middle height of the sand-blocking plate 5 can block the basin opening 11 to reduce the risk of pet sand splashing outside the basin body 1 due to the pet's digging, while the lower ends of the sand-blocking plate 5 ensure sufficient space at the top of the basin opening 11 for the pet to freely enter and exit the basin body 1.

[0037] Example 2

[0038] The second embodiment of this utility model relates to a base for a pet litter box, such as... Figure 1 and Figure 9 As shown, the base 2 has a accommodating space 22 for installing the basin 1 as described in Embodiment 1, and a waste discharge port 21 communicating with the accommodating space 22.

[0039] Among them, combined Figure 1 As shown, the waste discharge port 21 has an inlet side 211 and an outlet side 212 opposite to the inlet side 211. The inlet side 211 is used to be closed by the basin 1 when the basin 1 is flipped to the initial position and is flexibly sealed with the basin 1.

[0040] As can be seen from the above, since the base 2 is provided with a receiving space 22 and a waste discharge port 21 connected to the receiving space 22, the basin 1 of the pet litter box can be installed through the receiving space 22, so that the basin 1 can be flipped around a preset axis direction to pour out the collected excrement and / or waste through the waste discharge port 21 on the base 2. After the basin 1 has finished emptying the excrement and / or waste, it can be flipped back to the initial position, so that the inlet side 211 of the waste discharge port 21 on the base 2 can be resealed by the basin 1 and a flexible seal is achieved with the basin 1. This not only isolates the waste discharge port 21 from the outside world, effectively preventing the odor generated in the collection container 6 from overflowing into the outside environment, but also simplifies the structure of the pet litter box and reduces the design difficulty and production cost of the pet litter box.

[0041] Specifically, in some embodiments, such as Figure 1 and Figure 9 As shown, the base 2 includes: a bottom 23 and a side portion 24 surrounding the bottom 23, with the side portion 24 forming an accommodating space 22 on the bottom 23. The bottom 23 is provided with a waste discharge port 21 communicating with the accommodating space 22. Furthermore, combined with... Figure 2 As shown, the bottom 23, facing the accommodating space 22, also has an outer peripheral surface 232 forming an inlet side 211 of the waste discharge port 21, so that when the basin 1 is flipped to the initial position, as Figure 1 and Figure 2 As shown, the outer peripheral surface 232 can fit against the sealing element 3 on the basin body 1, so that the inlet side 211 of the waste discharge port 21 can be flexibly sealed with the basin body 1. Alternatively, when the basin body 1 is flipped to the initial position, the flexible sealing part 32 of the sealing element 3 can be inserted into the waste discharge port 21 and can be press-fitted with the flexible sealing part 32 of the sealing element 3. In this way, the inlet side 211 of the waste discharge port 21 can also achieve a flexible seal with the basin body 1.

[0042] Furthermore, as a preferred embodiment, in some other embodiments, the side of the bottom 23 facing into the receiving space 22 is a second spherical surface. Alternatively, in some other embodiments, combined with... Figure 9 As shown, the side of the bottom 23 facing the accommodating space 22 is a second arc surface 231, and the second arc surface 231 extends along the flipping direction of the basin 1, so that the vertical distance from any point on the second arc surface 231 to the preset axis is equal, thereby ensuring that the basin 1 has a large flipping angle within the accommodating space 22 of the base 2. Furthermore, in other embodiments, it is not difficult to see from the solution of Embodiment 1 that, as... Figure 4As shown, since the side of the bottom 13 of the basin 1 away from the opening 11 is a first arc surface 131, and the first arc surface 131 and the second arc surface 231 on the side of the bottom 23 facing the accommodating space 22 have the same radius of curvature, when the basin 1 is flipped, the gap between the basin 1 and the base 2 can be kept small, thereby preventing the pet from crawling into the gap and effectively avoiding the phenomenon of the pet being pinched.

[0043] Furthermore, based on the scheme of Embodiment 1, since a sealing element 3 is provided on the side of the basin bottom 13 away from the basin opening 11, when the flexible sealing part 32 of the sealing element 3 and the outer peripheral surface 232 are fitted together to achieve a flexible seal between the basin 1 and the inlet side 211 of the waste discharge port 21, as a preferred solution, in some other embodiments, such as... Figure 2 As shown, the outer peripheral surface 232 can protrude into the accommodating space 22, creating a certain height difference between the outer peripheral surface 232 and the second arc surface 231. Therefore, when the basin 1 is flipped to the initial position, the outer peripheral surface 232 can fit more tightly with the flexible sealing part 32 of the sealing element 3, thereby improving the sealing performance between the inlet side 211 of the sewage discharge port 21 and the basin 1. Simultaneously, the height difference between the second arc surface 231 and the outer peripheral surface 232 allows a gap 25 to be formed between the second arc surface 231 and the basin 1, such as... Figure 2 As shown, the gap 25 allows the flexible sealing portion 32 of the seal 3 to at least partially penetrate the basin 1 when it is tilted. This reduces the frictional resistance between the flexible sealing portion 32 and the second arc surface 231, making the tilting of the basin 1 smoother. Alternatively, in other embodiments, the gap 25 can be appropriately increased, or the length of the flexible sealing portion 32 can be appropriately shortened. This allows the flexible sealing portion 32 to completely separate from the second arc surface 23 after penetrating the gap 25, preventing the basin 1 from experiencing any resistance from the second arc surface 231 during tilting and effectively preventing the basin 1 from jamming during tilting.

[0044] Example 3

[0045] Embodiment 3 of this utility model relates to a sealing element for a pet litter box, such as... Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the sealing member 3 is disposed between the basin 1 as described in Embodiment 1 and the base 2 as described in Embodiment 2. The sealing member 3 is used to flexibly seal the inlet side 211 of the waste discharge port 21 of the base 2 with the basin 1 when the basin 1 is flipped to the initial position around the preset axis.

[0046] As can be seen from the above, after the litter box 1 has finished emptying excrement and / or waste, it can be flipped back to its initial position, so that the litter box 1 can seal the waste discharge port 21 on the base 2 and achieve a flexible seal with the inlet side 211 of the waste discharge port 21. This not only isolates the waste discharge port 21 from the outside world and effectively prevents the odor generated in the litter box 6 from overflowing into the outside environment, but also simplifies the structure of the pet litter box and reduces the design difficulty and production cost of the pet litter box.

[0047] Specifically, in some embodiments, the structure of the seal 3 can adopt the structure of the seal in Embodiment 1, that is, the seal 3 is an annular structure for sealing the inlet side 211 of the sewage discharge port 21, and as shown in the figure. Figure 2 and Figure 6 As shown, the sealing element 3 includes: a mounting portion 31 and a flexible sealing portion 32 connected to the mounting portion 31. Furthermore, it is easy to see from the solutions of Embodiments 1 and 2 above that, since the sealing element 3 is detachably mounted on the basin 1, and the sealing element 3 and the base 2 form an outer peripheral surface 232 that surrounds the inlet side 211 of the waste discharge port 21, a flexible seal is achieved between the basin 1 and the base 2. Of course, in other embodiments, the sealing element 3 can also be detachably mounted on the base 2, so that when the basin 1 is flipped to the initial position, a flexible seal can also be achieved between the basin 1 and the inlet side 211 of the waste discharge port 21, thus ensuring the sealing performance between the basin 1 and the inlet side 211 of the waste discharge port 21.

[0048] Furthermore, as a preferred embodiment, in some embodiments, the flexible sealing portion 32 of the seal 3 is used to deform when flexibly sealing the inlet side 211 of the waste discharge port 21 with the basin body 1. Simultaneously, the flexible sealing portion 32 is also used to spring back to its initial state when the flexible seal between the inlet side of the waste discharge port 21 and the basin body 1 is released. To achieve this characteristic of the flexible sealing portion 32 of the seal 3, in some embodiments, such as... Figure 6 As shown, the flexible sealing part 32 gradually expands in cross-section from one end away from the mounting part 31 to the other end. This results in a smaller cross-sectional diameter at the end of the flexible sealing part 32 away from the mounting part 31, providing sufficient flexibility to ensure a seal between the basin 1 and the inlet side 211 of the waste discharge port 2, while also reducing the resistance of the basin 1 during tilting, thus effectively improving the tilting performance of the basin 1. Conversely, the end of the flexible sealing part 32 connected to the mounting part 31 can have a larger cross-sectional diameter, providing sufficient rigidity and support. This allows the flexible sealing part 32 to return to its initial state when the basin 1 tilts away from its initial position, effectively ensuring a seal between the flexible sealing part 32 and the inlet side 211 of the waste discharge port 2.

[0049] Of course, as an alternative, in order to enable the flexible sealing part 32 to have certain deformation characteristics, in some other embodiments, the flexible sealing part 32 can also be a hollow structure with a hollow interior. Of course, in other embodiments, the sealing element 3 as a whole can also be made of flexible materials such as rubber or silicone, so that the flexible sealing part 32 can also have certain deformation characteristics to ensure the sealing performance between the basin 1 and the inlet side 211 of the sewage discharge port 21. In this embodiment, the structure and material of the sealing element 3 are not specifically limited.

[0050] Example 4

[0051] The fourth embodiment of this utility model relates to a pet litter box, such as... Figure 10 As shown, the pet litter box includes: a base 2 as described in Embodiment 2, a basin body 1 as described in Embodiment 1, and a sealing element 3 as described in Embodiment 3.

[0052] The basin 1 is at least partially embedded within the receiving space 22 of the base 2, and the basin 1 is rotatable about a predetermined axis. Furthermore, a collection container 6 is detachably disposed on the bottom 23 of the base 2, away from the receiving space 22, and the collection container 6 communicates with the receiving space 22 via a waste discharge port 21. This allows the basin 1 to receive excrement and / or waste poured out of the basin 1 when it is rotated to the waste-pouring position, and to receive excrement and / or waste poured out of the basin 1 via the waste discharge port 21 when the basin 1 is rotated back to the initial position. Figure 1 and Figure 5 As shown, the basin 1 can also be flexibly sealed to the inlet side 211 of the sewage discharge port 21 through the sealing element 3.

[0053] As can be seen from the above, after the litter box 1 has finished emptying excrement and / or waste, it can be flipped back to its initial position, so that the litter box 1 can seal the waste discharge port 21 on the base 2 and achieve a flexible seal with the inlet side 211 of the waste discharge port 21. This not only isolates the waste discharge port 21 from the outside world and effectively prevents the odor generated in the litter box 6 from overflowing into the outside environment, but also simplifies the structure of the pet litter box and reduces the design difficulty and production cost of the pet litter box.

[0054] Those skilled in the art will understand that the above embodiments are specific implementations of the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
