[0002] This application relates to the technical field of pet supplies, and particularly to an excrement storage container structure and a cat toilet, a door assembly and an excrement storage container, and an excrement storage container of a cat toilet and a cat toilet.

Background Art

[0003] With the advent of cat toilets, the time-consuming excrement removal work for cat owners has been eliminated, improving the breeding experience. The operating principle of currently commercially available automatic cat toilet devices is as follows. Cat litter is spread in a rotating drum and a screen is provided in the rotating drum. After the cat excretes on the cat litter, the cat litter solidifies and combines to form a solid mass. Further, through the rotation of the rotating drum and the cooperation of the screen, the separation of the cat litter and the solid mass is realized, and the solid mass is discharged into the excrement storage container.

[0004] However, the opening of the excrement storage container in conventional automatic cat toilet devices is often designed to be always open. Therefore, during use, the odor of the solid mass in the excrement storage container diffuses, affecting the user experience.

[0005] The introduction of cat litter boxes significantly improves the cat-owning experience for cat owners. The operating principle of currently available automatic cat litter boxes is as follows: Cat litter is packed into a rotating drum, and a screen is installed inside the rotating drum. After the cat defecates on the cat litter, the litter combines with the litter to form a clump. The rotation of the drum and the screen work together to separate the cat litter from the clump, and the clump is then discharged into a waste collection container.

[0006] Currently, the opening of the waste container in many automatic cat litter boxes is often designed to be open at all times. As a result, the odor of solidified waste escapes during use, affecting the user experience. To solve this problem, some waste containers have a container door installed at the opening to reduce the escape of solidified waste odor. However, conventional container doors are often directly attached to the opening, making them difficult to remove and cumbersome to clean.

[0007] The introduction of automatic cat litter boxes eliminates the time-consuming and laborious task of removing waste for cat owners, improving the cat-owning experience. The operating principle of currently available automatic cat litter boxes is as follows: Cat litter is packed into a rotating drum, and a screen is installed inside the rotating drum. After the cat defecates on the cat litter, the cat litter combines with the litter to form a clump. The rotation of the drum and the screen work together to separate the cat litter from the clump, and the clump is then discharged into a waste collection container.

[0008] Because the volume of the waste collection container is limited, it is necessary to monitor in real time whether the waste collection container is full or not, thereby enabling real-time cleaning of the waste collection container. Therefore, conventional automatic cat litter machines have a detection device in the waste collection container to detect whether it is full or not, but this device can only detect whether it is full or not, and cannot detect the remaining capacity.

[0029] In view of this, the purpose of this application is to provide a door assembly and a waste container, thereby solving the technical problems of conventional container doors being inconvenient to remove and container doors being complicated to clean.

[0030] To achieve the above technical objective, this application provides a door assembly comprising a container door and a container door bracket, The container door is provided with a first insertion portion.

The door assembly is attached to the opening. The container door of the door assembly is connected to the container body via a container door bracket.

[0040] As can be seen from the above technical solutions, the door assembly designed in this application involves installing an additional container door bracket, utilizing the interlocking fit between the first and second insertion parts, and further locking the connection between the container door and the container door bracket by the locking fit between the first and second lock parts.

[0041] In view of this, the purpose of this application is to solve the technical problem that conventional waste containers do not have a remaining capacity detection function by providing a waste container and a cat litter box for cats.

[0052] As can be seen from the above technical solutions, the waste collection container for cat litter designed in this application has a remaining capacity detection function by detecting the remaining capacity of the storage cavity inside the waste collection container body using a remaining capacity detection device. Compared to conventional methods that can only detect whether or not it is full, it is easier for pet owners to understand the remaining capacity status of the storage cavity inside the waste collection container body in real time, and as a result the waste collection container body can be cleaned in advance based on the remaining capacity status, thereby avoiding overflow situations and providing a better user experience.

[Modes for carrying out the invention]

For example, they may be fixedly connected, interchangeably connected, integrally connected, mechanically connected, electrically connected, directly connected, indirectly connected via an intermediate medium, or internally connected to two elements. Those skilled in the art will be able to understand the specific meaning of these terms in the embodiments of this application depending on the specific circumstances.

[0058] Embodiments of this application disclose a structure for a waste container.

[0059] Referring to Figure 1, one embodiment of the waste container structure according to the present application is: It includes a container body 100 and a container cover 200.

[0060] The container body 100 is provided with a containment cavity for accommodating the solid, and the top of the container body 100 is provided with an opening that communicates with the containment cavity.

[0061] The container cover 200 includes a container door 2 and a drive mechanism 3, the drive mechanism 3 being connected to the container door 2 and used to open and close the opening by driving the container door 2 to move. The container cover 200 may be attached directly to the opening, or the opening may extend upward to form an extending passage, and the container cover 200 may be attached to the extending passage, without specific limitations.

[0062] By using the drive mechanism 3 to move the container door 2, the opening can be opened and closed, allowing the opening to open properly to allow solid waste to fall out when the waste container is in use, and closing when not in use. This ensures that the waste container is sealed for most of the time, preventing odors from escaping from the waste container and affecting the user experience.

[0063] The above describes Embodiment 1 of the excrement container structure according to the present application, and the following describes Embodiment 2 of the excrement container structure according to the present application, specifically referring to Figures 1 to 7.

[0064] Based on the solution of Embodiment 1 described above, Furthermore, as shown in Figure 2, the design of the drive mechanism 3 includes a driver 31 and a rotating shaft 32.

[0065] The drive end of the drive unit 31 is connected to the rotating shaft 32 and is used to rotate the rotating shaft 32, and the container door 2 is also connected to the rotating shaft 32. The drive unit 31 is a rotary motor that can rotate in both forward and reverse directions, and by rotating the rotating shaft 32, it causes the container door 2 to open and close relative to the opening.

[0066] Furthermore, as shown in Figure 2, the drive end of the driver 31 can be connected to the rotating shaft 32 via a transmission assembly 33. The transmission assembly 33 may be a gear transmission structure, a pulley transmission structure, etc., and is not specifically limited. By using the transmission assembly 33 to achieve the transmission connection, the axial connection dimension between the driver 31 and the rotating shaft 32 can be shortened, the structure becomes more compact, and the attachment and detachment of the rotating shaft 32 and the driver 31 becomes easier, which is advantageous for maintenance. Of course, if necessary, the drive end of the driver 31 may be directly connected to one end of the rotating shaft 32, and is not specifically limited.

[0067] Furthermore, as shown in Figures 2, 4, and 7, whether or not the container door 2 is fully opened or closed is usually detected by a Hall sensor, and some detection errors are unavoidable, resulting in the container door 2 not being fully opened or closed. To solve this problem, the transmission assembly is specifically designed to include a driving gear 331 and a driven gear 332.

[0068] The drive end of the drive unit 31 is connected to the drive gear 331 and is used to rotate the drive gear 331. The driven gear 332 is elastically rotatably connected to the rotating shaft 32 via an elastic member 334, and the drive gear 331 rotates the rotating shaft 32 by meshing with the driven gear 332. With this design, when opening and closing the container door 2, the driven gear 332 is driven to rotate the rotating shaft 32 via the elastic member 4, and when the container door 2 is completely closed, the drive gear 331 continues to rotate by a certain angle, at which time the position of the container door 2 does not change, but the elastic member 334 is compressed or stretched, thereby providing elasticity to ensure that the container door 2 is securely closed.

[0069] Regarding the design of the driven gear 332, it may be a complete gear design, and taking the complete gear design as an example, one additional sensor may be installed to detect the rotation angle of the driven gear 332, thereby avoiding excessive compression or tension of the elastic member 334.

[0070] Of course, an incomplete gear design is also possible, for example, in which the driving gear 331 meshes with the incomplete teeth 333 of the driven gear 332. When the driving gear 331 meshes with one tooth on the edge of the incomplete teeth 333 of the driven gear 332, if the driver 31 continues to rotate the driving gear 331, the gear will slip and produce a "dada" sound, which indicates that the container door 2 has reached a predetermined position and is being elastically pressed by the elastic member 2. Thus, using an incomplete gear design not only solves the problem of overcompressing or overstretching the elastic member 334, but also enables the indication that the container door 2 has reached its position, and is less expensive and more effective than a complete gear design. The span of the incomplete teeth 333 of the driven gear 332 may be set within an angular range as needed and is not specifically limited.

[0071] Furthermore, as shown in Figure 7, the elastic member 334 is preferably a torsion spring. The driven gear 332 is rotatably mounted to one end of the rotating shaft 32, and the elastic member 334 is fitted onto the rotating shaft 32, with one torque arm connected to the rotating shaft 32 and the other torque arm connected to the driven gear 332.

[0072] Furthermore, as shown in Figure 1, the container cover 200 further includes a frame 1 to facilitate the installation and placement of the drive mechanism 3.

[0073] Frame 1 is attached to the opening, and a through cavity communicating with the opening is formed in the center. The drive mechanism 3 is attached to Frame 1 and is used to open and close the through cavity by driving the container door 2 to move. In other words, the drive mechanism 3 controls the opening and closing of the through cavity by driving the container door 2 to move, and further controls the opening and closing of the opening.

[0074] Furthermore, as shown in Figure 3, in order to facilitate the contact and fitting of the container door 2 and the frame 1, a step 121 is provided at one end of the through cavity away from the opening, which can contact and abut against the container door 2.

[0075] Furthermore, as shown in Figures 2 and 3, the drive mechanism 3 may be designed to include a rotating member 34 and a container door bracket 35 in order to realize the opening and closing control of the container door 2.

[0076] The rotating member 34 is fixed to one side of the rotating shaft 32 and is movably inserted into the through cavity, the container door bracket 35 is hinged to the rotating member 34, and the container door 2 is attached to the container door bracket 35. As can be understood, when the drive unit 31 rotates the rotating member 34 upward by a certain angle by the rotating shaft 32, the container door bracket 35 and the rotating member 34 are rotatably connected and fitted together, so that under the gravitational force of the container door bracket 35 and the container door 2 themselves, the container door bracket 35 rotates relative to the rotating member 34, making the container door 2 vertical, i.e., opening the container door 2. When the drive unit 31 rotates the rotating member 34 downward by a certain angle by the rotating shaft 32, the rotating member 34 and the container door bracket 35 are rotatably connected, so the container door bracket 35 rotates relative to the rotating member 34, making the container door 2 contact the stairs 121 again, i.e., closing the container door 2.

[0077] Furthermore, as shown in Figure 5, a roller 353 that rolls and makes contact with the stairs 121 is pivotally supported on the container door bracket 35. By installing the roller 353, the fitting between the container door 2 and the stairs 121 can be made smoother.

[0078] Furthermore, the container door 2 is detachably connected to and fitted into the container door bracket 35, making it easy to clean or replace the container door 2.

[0079] Furthermore, as shown in Figure 3, the stairs 121 are provided at an overall angle, thereby positioning the container door 2 at an angle when it is closed. This design makes opening and closing the container door 2 easier. Specifically, the upper part of the frame 1 may be made into an inclined structure, so that the stairs 121 formed on the upper edge of the through cavity of the frame 1 are provided at an overall angle. For example, the stairs 121 are provided at an angle downward from one edge to the other edge of itself, and the pivot shaft 32 may be, but is not specifically limited, positioned below one edge of the stairs 121. For example, when it is necessary to open the container door 2, the drive unit 31 rotates, rotating the pivot shaft 32 via the transmission assembly 33, and further rotating the rotating member 34 diagonally upward, and when it is necessary to close the container door 2, the drive unit 31 reverses, rotating the pivot shaft 32 via the transmission assembly 33, and further rotating the rotating member 34 diagonally downward.

[0080] Furthermore, as shown in Figure 3, the frame 1 of this application is designed to include a lower frame 11 and an upper frame 12.

[0081] The upper frame 12 is detachably attached to the upper part of the lower frame 11, and may, but is not limited to, being fixed to the lower frame 11 by fastening members such as screws.

[0082] As shown in Figures 4 and 6, a first position limiting portion 111 is provided on the upper part of the lower frame 11, and a second position limiting portion 123 is provided on the bottom of the upper frame 12. When the upper frame 12 is attached to the lower frame 11, a rotation cavity is formed between the first position limiting portion 111 and the second position limiting portion 123 for rotatably mounting the rotating shaft 32. Avoidance grooves 112 are provided in both the lower frame 11 and the upper frame 12 to prevent rotation of the rotating member 34. Similarly, when the lower frame 11 and the upper frame 12 are attached and fitted together, corresponding mounting cavities for mounting the drive unit 31 and the transmission assembly 33 may be further formed, but are not specifically limited.

[0083] Furthermore, the design of the first position limiting portion 111 may include a first groove for engaging the rotating shaft 32, and this first groove may be a semi-cylindrical groove that conforms to the length of the rotating shaft 32, as shown in Figure 4.

[0084] Multiple rib plates 122 are provided at the bottom of the upper frame 12, and the second position limiting portion 123 is provided at the bottom of the rib plate 122 and is a second groove for engaging with the rotating shaft, and the second groove is an arc-shaped groove that matches the arc of the rotating shaft 32. Furthermore, the design of the rib plates 122 can also strengthen the structural strength of the upper frame 12.

[0085] The above design also allows for the formation of a rotating cavity between the first groove and the second groove. The axial position of the rotating shaft 32 may be restricted by the transmission assembly 33, or by utilizing the end of the first groove; it is not specifically restricted.

[0086] In this application, by designing the frame 1 as a combination of an upper frame 12 and a lower frame 11, the mounting and detachment of the drive mechanism 3 is made easier, which is advantageous for maintenance.

[0087] Furthermore, the rotating member 34 and the container door bracket 35 are preferably designed to be detachably connected and fitted together for easy maintenance, specifically, as shown in Figures 6 and 7, the rotating member 34 is provided with a connecting shaft 341. The rotating member 34 may include two side plates, which are installed parallel to each other and one end of which is connected to the rotating shaft 32, a connecting plate is installed between the two side plates, and the connecting shaft 341 is connected between the other ends of the two side plates. The design may be modified as needed in practice and is not limited to this.

[0088] The container door bracket 35 is provided with a plurality of locking grooves 351 having a certain amount of deformation, that is, the width of the locking grooves 351 can be elastically changed within a certain range, which is advantageous for connection and fitting.

[0089] A position limiting block 352 is further provided within the locking groove 351, and the connecting shaft 341 engages with the locking groove 351 via the position limiting block 352 and rotates into the locking groove 351.

[0090] The position limiting block 352 is used to prevent the connecting shaft 341 from falling out. When installing, by pressing the connecting shaft 341 with some force, the connecting shaft 341 overcomes the elastic force of the locking groove 351, thereby allowing it to engage with the locking groove 351 via the position limiting block 352. When removing, the connecting shaft 341 can be removed from the locking groove 351 with some force, enabling the quick removal of the container door bracket 35 and the rotating member 34.

[0091] The container door bracket 35 also acts as a counterweight, and after being connected to the container door 2, the container door 2 can more smoothly flip downward when the rotating member 34 rotates upward, becoming vertical and thereby opening.

[0092] Furthermore, as shown in Figure 1, a handle 101 is provided on one side of the container body 100 for easier handling.

[0093] Furthermore, as shown in Figure 2, since the opening of the container body 100 is generally designed to be small, when the garbage bag inside is full of solidified garbage it is difficult to remove from the opening. To make it easier to remove the garbage bag full of solidified garbage, this application further provides one opening 102 on the side of the container body 100, and this opening 102 may be specifically provided on the opposite side of the handle 101, or one removable sealing plate may be added and installed, and the opening 102 may be sealed when not in use, and is not specifically limited.

[0094] The waste container structure designed in this application opens the container door 2 when it is necessary to accept solid waste and closes the container door 2 at other times. In this way, the waste container is sealed for most of the time without affecting the normal function of the waste container, preventing the release of odors from inside the waste container and improving the user experience.

[0095] This application further discloses a cat litter box, comprising a base, a rotating drum, and the waste collection container structure of Embodiment 1 or Embodiment 2 described above.

[0096] Both the rotating drum and the waste collection container structure are mounted on a base. The waste collection container structure is used to collect clumps separated from the rotating drum. The base is equipped with a rotating drum drive assembly to drive the rotating drum, which separates the cat litter from the clumps inside by rotating the drum. The clumps separated from the rotating drum fall into the container body through the clump discharge opening. Additionally, a handle on one side of the container body is exposed from the base for easier handling.

[0097] The excrement container structure and cat litter box described in this application have been presented in detail above. Those skilled in the art can modify the specific embodiments and scope of application based on the concept of the embodiments described in this application, and therefore, the contents of this specification should not be understood as limiting this application.

[0098] Embodiments of this application disclose a door assembly.

[0099] Referring to Figures 8 and 10, one embodiment of the door assembly according to the present application is: It includes a container door 100 and a container door bracket 200.

[0100] The container door 100 is provided with a first insertion portion 11, and the container door bracket 200 is provided with a second insertion portion 21 that fits into the first insertion portion 11.

[0101] A first locking portion 12 is further provided on the container door 100, and a second locking portion 22 is further provided on the container door bracket 200 that can lock and fit into the first locking portion 12. When the first insertion portion 11 is fully inserted into the second insertion portion 21, the first locking portion 12 locks and fits into the second locking portion 22.

[0102] The door assembly designed in this application involves installing an additional container door bracket 200, utilizing the interlocking fit between the first insertion part 11 and the second insertion part 21, and further locking the connection between the container door 100 and the container door bracket 200 through the locking fit between the first locking part 12 and the second locking part 22. When the first insertion part 11 is fully connected to the second insertion part 21, the lock is achieved by the interlocking of the first locking part 12 and the second locking part 22, enabling a quick connection between the container door bracket 200 and the container door 100. When it is necessary to remove the container door 100, the connection between the first locking part 12 and the second locking part 22 is unlocked, allowing the container door 100 to be quickly removed, improving the convenience of cleaning the container door 100.

[0103] The above describes Embodiment 1 of the door assembly according to the present application, and the following describes Embodiment 2 of the door assembly according to the present application, specifically referring to Figures 8 to 11.

[0104] Based on the solution of Embodiment 1 described above, Furthermore, as shown in Figures 8 to 10, regarding the method of insertion and fitting, the second insertion portion 21 may be designed as a female-side fitting structure for movably inserting the first insertion portion 11, which is a male-side fitting structure. To make this clear, the second insertion portion 21 is an insertion groove structure, and as an example, the second locking portion 22 may be provided inside the second insertion portion 21.

[0105] Accordingly, the first insertion portion 11 is provided with a clearance groove 111 for inserting the second locking portion 22, and the first locking portion 12 is provided within the clearance groove 111, making it easier to lock and fit into the second locking portion 22. By integrating the first locking portion 12 and the first insertion portion 11, and integrating the second locking portion 22 and the second insertion portion 21, the structure can be further optimized and the overall structure can be made more compact.

[0106] Of course, the embodiments shown above may be designed in reverse, namely, the second insertion portion 21 having a male-side fitting structure, and the first insertion portion 11 having a female-side fitting structure for inserting the second insertion portion 21. The first locking portion 12 is provided correspondingly within the first insertion portion 11, the second insertion portion 21 is provided with a clearance groove 111 for inserting the first locking portion 12, and the second locking portion 22 is provided within the insertion portion. Those skilled in the art may, and are not limited, make appropriate modifications based on this.

[0107] Furthermore, the second insertion portion 21 may have a substantially U-shaped groove structure, and correspondingly the first insertion portion 11 has a substantially U-shaped frame structure. The first insertion portion 11 is designed to have a substantially U-shaped frame structure, which not only allows it to be used as a male-side fitting structure, but also allows for the formation of a corresponding avoidance groove 111 for inserting the second locking portion 22. Of course, it may have other shapes and structures, as long as the above-mentioned insertion and fitting requirements are met and the locking fitting between the first locking portion 12 and the second locking portion 22 is achieved.

[0108] Furthermore, in order to facilitate locking or unlocking the first locking part 12 and the second locking part 22, the first locking part 12 and the second locking part 22 may be designed to be fitted together using a snap-fit ​​method.

[0109] Furthermore, as shown in Figures 9 to 11, taking a snap-fit ​​fitting as an example, the first locking portion 12 may be designed as a locking groove, and the second locking portion 22 may be designed as a fastener having a certain elastic deformation, and a projection that can engage with the locking groove is provided at one end of the fastener away from the container door bracket 200. The second locking portion 22 may be integrally molded with the container door bracket 200. The elastic deformation design allows for the use of elastic force when the projection of the second locking portion 22 engages with the first locking portion 12, enabling displacement changes when the projection receives a certain external force, and also facilitating locking with the first locking portion 12. When unlocking, the fastener is deformed by an external force, causing the projection to detach from the first locking portion 12, thus completing the unlocking process, and making unlocking easy.

[0110] Furthermore, as shown in Figure 9, an annular flange 13 may be provided at the bottom of the container door 100, and a locking groove is formed between the annular flange 13 and the bottom of the container door 100.

[0111] A first guide portion 131 is provided on the outside of the annular flange 13 to guide the projection so that it slides into the locking groove, and a second guide portion 132 is provided on the inside of the annular flange 13 to guide the projection so that it slides out of the locking groove.

[0112] In the process of fully inserting and fitting the first insertion portion 11 into the second insertion portion 21, the projection passes through the first guide portion 131 and the second guide portion 132 and enters the locking groove. As the projection passes through the first guide portion 131, it is displaced away from the container door 100, thereby deforming the second locking portion 22. As it passes through the second guide portion 132, the deformation is restored, and the projection engages well within the locking groove. When unlocking is required, applying a force in the separation direction to the first insertion portion 11 and the second insertion portion 21 moves them in the separation direction. In the process, the projection passes through the second guide portion 132 and the first guide portion 131 and slides out of the locking groove, thereby completing the unlocking.

[0113] In this design, the design of the first guide portion 131 facilitates the sliding of the projection into the locking groove, thereby improving the convenience of locking. The design of the second guide portion 132 facilitates the sliding of the projection out of the locking groove, thereby improving the convenience of unlocking the lock.

[0114] In this application, only the first guide section 131 may be designed, or only the second guide section 132 may be designed, and the choice may be made as specifically required by the actual circumstances, and is not limited.

[0115] In this application, the first guide portion 131 and the second guide portion 132 may be inclined ribs connecting the side surface of the locking groove and the bottom of the container door 100, and are not specifically limited.

[0116] Furthermore, as shown in Figures 9 to 11, the first insertion portion 11 is provided with a position limiting groove 112 along the direction in which it is inserted into and fitted into the second insertion portion 21.

[0117] One end of the position limiting groove 112 extends from the first insertion portion 11, and the other end is provided to seal it. The second insertion portion 21 is provided with a position limiting edge 211 that is movably inserted into the position limiting groove 112 via one end of the position limiting groove 112. The fitting design of the position limiting groove 112 and the position limiting edge 211 further improves the reliability of the fitting between the first insertion portion 11 and the second insertion portion 21, thereby improving the reliability of the fitting between the container door 100 and the container door 100.

[0118] Furthermore, as shown in Figure 11, two position-restricting grooves 112 may be designed, each provided on two sides of the first insertion portion 11, and correspondingly, two position-restricting edges 211 are also designed to fit into the position-restricting grooves 112 in a one-to-one correspondence.

[0119] Furthermore, as shown in Figure 8, multiple reinforcing ribs 23 can be provided on the container door bracket 200 to improve its strength.

[0120] As shown in Figure 12, this application further discloses an excrement container, which includes a container body 300 and a door assembly of Embodiment 1 or Embodiment 2 described above.

[0121] An opening 31 is provided in the container body 300, the door assembly is attached to the opening 31, and the container door 100 of the door assembly is connected to the container body 300 via a container door bracket 200.

[0122] Regarding the connection design between the container door bracket 200 and the container body 300, the container door bracket 200 may be directly connected to the container body 300 with a hinge, or a hinge connection with the container body 300 may be achieved via the rotating member 4.

[0123] As an example of the connection method for the rotating member 4, one end of the rotating member 4 is connected to the container body 300 by a hinge, and the other end is connected to the container door bracket 200 by a hinge. The rotating member 4 is rotated by a drive mechanism, and the container door 100 can be opened and closed. The opening 31 may be provided with steps 32 that come into contact with and abut against the container door 100, thereby allowing the container door 100 to better shield the opening 31.

[0124] The door assembly and waste container relating to this application have been described in detail above. Those skilled in the art can modify the specific embodiments and scope of application based on the concept of the embodiments of this application, and therefore, the contents of this specification should not be understood as limiting this application.

[0125] Embodiments of this application disclose a waste collection container for a cat litter box.

[0126] Referring to Figure 13, one embodiment of the waste container for a cat litter box according to the present application is: It includes a waste collection container body 1 and a remaining capacity detection device 2.

[0127] The waste collection container body 1 is provided with a collection cavity for collecting solid waste, and the remaining volume detection device 2 is used to detect the remaining volume in the collection cavity.

[0128] The above design enables the waste container to have a remaining capacity detection function by detecting the remaining capacity of the storage cavity inside the waste container body 1 using the remaining capacity detection device 2. Compared to conventional methods that can only detect whether or not the container is full, this design makes it easier for pet owners to understand the remaining capacity status of the storage cavity inside the waste container body in real time. This allows them to clean the waste container body in advance based on the remaining capacity status, thus avoiding overflow situations and providing a better user experience.

[0129] The above describes Embodiment 1 of the excrement container for a cat litter box according to the present application, and the following describes Embodiment 2 of the excrement container for a cat litter box according to the present application, specifically referring to Figures 13 to 15.

[0130] Based on the solution of Embodiment 1 described above, Furthermore, as shown in Figure 15, the design of the remaining capacity detection device 2 includes a detection sensor and a processor.

[0131] The detection sensor 23 detects clumps within the containment cavity and acquires information.

[0132] The processor 22 is electrically connected to the detection sensor 23 and analyzes and processes the acquired information to obtain the remaining capacity of the storage cavity. The processor may be a PLC processor (PLC control board), a microprocessor, etc., and is not specifically limited.

[0133] Furthermore, the detection sensor 23 may also be a distance measuring sensor, which is used to measure the distance between itself and the mass inside the containment cavity.

[0134] Correspondingly, the processor 22 is used to compare the measured distance with a preset distance and obtain the remaining capacity of the storage cavity. In other words, the processor processes the distance measurement results and is used to determine the remaining capacity of the storage cavity.

[0135] Furthermore, taking the distance measuring sensor as an example, the detection sensor may be a TOF sensor, infrared sensor, laser sensor, ultrasonic sensor, or radar sensor.

[0136] As an example of the application of a TOF sensor, the TOF sensor approaches a mass within the containment cavity, irradiates the mass with infrared or laser light, and after the light reaches the mass, it reflects and returns to the TOF sensor. Based on the time difference between the time of irradiation and the time after the light is reflected by the object and returns to the sensor, the distance between the mass and the TOF sensor can be measured. The remaining capacity of the containment cavity corresponding to a preset distance can be obtained experimentally, and similarly, the relationship between the numerical change in the preset distance and the change in the remaining capacity of the containment cavity can also be obtained experimentally. Therefore, the processor 22 can compare the measured distance with the preset distance, determine the difference between it and the preset distance, substitute it into the relationship between the numerical change in the preset distance and the change in the remaining capacity of the containment cavity, and obtain the remaining capacity of the containment cavity. This will not be described in detail.

[0137] Furthermore, the detection sensor 23 may be an image sensor, used to acquire image information of the mass within the containment cavity, and accordingly, the processor 22 analyzes the acquired image information and uses it to obtain the remaining capacity of the containment cavity. More specifically, the processor 22 compares the acquired image information of the mass within the containment cavity with images of the waste containment container under multiple remaining capacity states pre-stored in the image library, identifies the image with the highest degree of match, and can use the remaining capacity of the waste containment container corresponding to that image as the current remaining capacity of the waste containment container.

[0138] Furthermore, because the shape of the clumps is irregular, that is, the clumps are not piled up flat in the waste container, preferably, the detection sensors 23 are designed in multiple numbers and distributed at intervals from one another. By integrating the detection data from multiple detection sensors 23, the remaining capacity of the container cavity can be determined, avoiding detection errors caused by the clumps not being piled up flat in the waste container, and making the determination more accurate.

[0139] Furthermore, the structural design of the waste container body 1 includes a container body 11 and a container cover 12. A containment cavity is provided inside the container body 11, and an opening communicating with the containment cavity is provided at the top of the container body 11. The container cover 12 is attached directly above the opening and is provided with a container door 121 that corresponds to the opening and can be opened and closed with control. When the container door 121 is opened, separated solids can fall out, and when the container door 121 is closed, the odor of the solids inside the containment cavity can be prevented from escaping, improving the user experience.

[0140] The detection sensor may be mounted on the container cover 12, on the container door 121, or on the top of the containment cavity. Of course, as shown in Figures 13 and 14, it may also be mounted in a position corresponding to the upper opening of the container cover 12, that is, mounted on the outside of the waste containment container body 1. To facilitate mounting and securing in an external location, the remaining capacity detection device 2 further includes a device housing 21, which provides mounting and securing positions for the processor 22 and the detection sensor 23, and the device housing 21 itself can be fixedly installed by fitting into other structures of the cat litter box, and the device housing 21 may be designed to include an upper housing 211 and a lower housing 212 detachably connected to the upper housing 211, and as shown in Figure 15, the processor 22 may be fixed between the upper housing 211 and the lower housing 212, and the detection sensor 23 may be fixed to the processor 22 and detect the inside of the housing cavity by corresponding detection avoidance holes in the lower housing 212, and those skilled in the art may make variations on this, without specific limitations.

[0141] Furthermore, to facilitate insertion and removal, a handle (not shown) may be attached to one side of the container body 11, and this handle may have a notch or a U-shaped handle structure that is easy to grip by hand.

[0142] Furthermore, a display screen (not shown) is electrically connected to the processor 22, and the processor 22 is further used to display the obtained remaining capacity information on the display screen. Of course, it may also be displayed by an app on a mobile terminal such as a mobile phone, and is not limited to that.

[0143] Furthermore, to provide real-time notification to the owner, an alarm (not shown) is further electrically connected to the processor 22, and the processor 22 is further used to activate the alarm and emit an alarm signal when it detects that the remaining capacity of the housing cavity is lower than an early alarm value, the alarm may be a buzzer alarm or an audible and visual alarm.

[0144] This application further discloses a cat litter box, which includes a base (not shown), a rotating drum (not shown), and a waste collection container for the cat litter box of Embodiment 1 or Embodiment 2 described above.

[0145] The waste collection container body 1 and the rotating drum of the cat litter box are mounted on a base, and the base is equipped with a drive mechanism for rotating the rotating drum, and the waste collection container body 1 is used to collect the clumps separated from the rotating drum.

[0146] As shown in Figures 13 and 14, for example, if the remaining volume detection device 2 of the cat litter box's waste collection container is mounted on the outside upper part of the waste collection container body 1, and the detection sensor 23 is a TOF sensor, when the container door 121 is opened, the TOF sensor can emit infrared or laser light, which can be directed at the solid waste inside the collection cavity.

[0147] Furthermore, the handle attached to one side of the container body 11 is preferably exposed from the base, making it easy to pick up.

[0148] The excrement container and cat litter box of the present application have been described in detail above. Those skilled in the art can modify the specific embodiments and scope of application based on the concept of the embodiments of this application, and therefore, the contents of this specification should not be understood as limiting this application.
