Description

Technical Field

[0001] This application relates to the field of pet supplies technology, and in particular to a waste collection chamber structure and a cat toilet. Background Technology

[0002] The introduction of cat litter boxes has solved the tedious and time-consuming task of scooping litter for cat owners, improving the pet ownership experience. Currently, the working principle of automatic cat litter boxes on the market is as follows: cat litter is laid in a rotating drum with a screen inside. After the cat defecates on the litter, the litter will clump together with the litter to form a clump. The rotation of the drum, together with the screen, separates the litter from the clump, and then the clump is discharged into the waste collection tank.

[0003] However, most current automatic cat litter boxes have an open design for the collection chamber, which causes odor to escape from the clumps of waste during use, affecting the user experience. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0066] This application discloses a stool collection chamber structure.

[0067] Please see Figure 1 One embodiment of a waste collection chamber structure provided in this application includes:

[0068] The storage body is 100 and the storage cover is 200.

[0069] The container 100 has a cavity for accommodating the clumps, and the top of the container 100 has an opening that connects to the cavity.

[0070] The bin cover 200 includes a bin door 2 and a drive mechanism 3; the drive mechanism 3 is connected to the bin door 2 and is used to drive the bin door 2 to move so that the opening is closed or opened. The bin cover 200 can be directly installed on the opening, or the opening can extend upward to form an extension channel, and the bin cover 200 can then be installed on the extension channel, without any specific restrictions.

[0071] The drive mechanism 3 is used to move the chamber door 2, so that the opening can be closed or opened. This ensures that the opening can be opened normally when the stool collection chamber is in use so that the stool can fall in, and can be closed when not in use, so that the stool collection chamber is in a sealed state most of the time, preventing the odor in the stool collection chamber from escaping and affecting the user experience.

[0072] The above is an embodiment of a stool collection chamber structure provided in this application. The following is an embodiment of a stool collection chamber structure provided in this application. Please refer to the following for details. Figures 1 to 7 .

[0073] Based on the solution of Embodiment 1 above:

[0074] Furthermore, such as Figure 2 As shown, the design of the drive mechanism 3 includes a driver 31 and a rotating shaft 32.

[0075] The drive end of the actuator 31 is connected to the rotating shaft 32 to drive the rotating shaft 32 to rotate. The compartment door 2 is connected to the rotating shaft 32. The actuator 31 is a rotary motor that can rotate in both directions. By driving the rotating shaft 32 to rotate, it drives the compartment door 2 to open and close.

[0076] Furthermore, such as Figure 2 As shown, the drive end of the driver 31 can be connected to the rotating shaft 32 via a transmission assembly 33. This transmission assembly 33 can be a gear transmission structure, a pulley transmission structure, etc., and is not specifically limited. Using the transmission assembly 33 to achieve the transmission connection can shorten the axial connection dimension between the driver 31 and the rotating shaft 32, resulting in a more compact structure. Furthermore, it facilitates the installation and disassembly of the rotating shaft 32 and the driver 31, making maintenance easier. Of course, depending on the needs, the drive end of the driver 31 can also be directly connected to one end of the rotating shaft 32, and there are specific limitations.

[0077] Furthermore, such as Figure 2 , Figure 4 as well as Figure 7 As shown, the opening and closing of the compartment door 2 is usually detected by a Hall sensor, which inevitably leads to some detection errors, causing the compartment door 2 to not open or close properly. To solve this problem, the transmission assembly is specifically designed to include a driving gear 331 and a driven gear 332.

[0078] The drive end of the actuator 31 is connected to the drive gear 331 to drive the drive gear 331 to rotate; the driven gear 332 is elastically rotatably connected to the rotating shaft 32 through the elastic element 334; the drive gear 331 meshes with the driven gear 332 to drive the rotating shaft 32 to rotate. With this design, when the compartment door 2 is opened or closed, the driven gear 332 drives the rotating shaft 32 to rotate through the elastic element 4. When the compartment door 2 is closed, the drive gear 331 continues to rotate at a certain angle. At this time, the position of the compartment door 2 does not change, but the elastic element 334 is compressed or stretched, thereby providing elastic force to make the compartment door 2 close tightly.

[0079] Regarding the design of the driven gear 332, it can be a complete gear design. In the case of a complete gear design, an additional sensor can be added to detect the rotation angle of the driven gear 332 in order to avoid excessive compression or stretching of the elastic element 334.

[0080] Of course, an incomplete gear design can also be used. Taking this as an example, the driving gear 331 and the driven gear 332 have incomplete tooth portions 333 meshing on each other. When the driving gear 331 engages with one tooth on the edge of the incomplete tooth portion 333 of the driven gear 332, if the driver 31 continues to drive the driving gear 331 to rotate, gear slippage will occur, producing a "clicking" sound to indicate that the compartment door 2 is in position and has been pressed down by the elastic element 2. It is evident that the incomplete gear design not only solves the problem of excessive compression or stretching of the elastic element 334, but also provides indication of the compartment door 2's position. Compared to a complete gear design, it is lower in cost and more effective. The span of the incomplete tooth portion 333 of the driven gear 332 can be set within an angle range according to actual needs, without specific limitations.

[0081] Furthermore, such as Figure 7 As shown, the elastic element 334 is preferably a torsion spring. The driven gear 332 is rotatably mounted on one end of the rotating shaft 32; the elastic element 334 is sleeved on 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.

[0082] Furthermore, such as Figure 1 As shown, to facilitate the installation and arrangement of the drive mechanism 3, the cover 200 also includes a frame 1.

[0083] A frame 1 is mounted on the opening, forming a central cavity that connects to the opening. A drive mechanism 3 is mounted on the frame 1 and is used to drive the door 2 to move, thereby closing or opening the central cavity. In other words, the drive mechanism 3 controls the opening or closing of the central cavity by driving the door 2 to move, thus controlling the opening or closing of the opening.

[0084] Furthermore, such as Figure 3As shown, in order to facilitate the overlapping and cooperation between the door 2 and the frame 1, a step 121 is provided around the end of the central cavity away from the opening, which can contact and abut against the door 2.

[0085] Furthermore, such as Figure 2 as well as Figure 3 As shown, in terms of the opening and closing control of the warehouse door 2, the drive mechanism 3 can also be designed to include a rotating part 34 and a warehouse door bracket 35.

[0086] The rotating component 34 is fixed to one side of the rotating shaft 32 and extends movably into the central cavity; the door bracket 35 is hinged to the rotating component 34; the door 2 is mounted on the door bracket 35. It can be understood that when the actuator 31 drives the rotating component 34 to rotate upwards by a certain angle via the rotating shaft 32, because the door bracket 35 and the rotating component 34 are rotatably connected, the door bracket 35 rotates relative to the rotating component 34 under the weight of the door bracket 35 and the door 2 itself, causing the door 2 to be in a vertical position, i.e., the door 2 is open. When the actuator 31 drives the rotating component 34 to rotate downwards by a certain angle via the rotating shaft 32, because the rotating component 34 and the door bracket 35 are rotatably connected, the door bracket 35 rotates relative to the rotating component 34, causing the door 2 to re-attach to the step 121, i.e., the door 2 is closed.

[0087] Furthermore, such as Figure 5 As shown, a roller 353 is pivotally connected to the door support 35, which rolls in contact with the step 121. The roller 353 makes the fit between the door 2 and the step 121 smoother.

[0088] Furthermore, the door 2 and the door bracket 35 are detachably connected, making it easy to clean or replace the door 2.

[0089] Furthermore, such as Figure 3 As shown, the step 121 is inclined, so that the closed door 2 is also inclined. This design makes opening and closing the door 2 more convenient. Specifically, the top of the frame 1 can be inclined, so that the step 121 formed by the top edge of the central cavity of the frame 1 is also inclined. Taking the step 121 as inclined downward from one edge to the other as an example, the rotating shaft 32 can be located below one edge of the step 121, and there is no specific limitation. Taking this example, when the door 2 needs to be opened, the driver 31 rotates, which drives the rotating shaft 32 to rotate through the transmission component 33, and then drives the rotating part 34 to rotate obliquely upward; when the door 2 needs to be closed, the driver 31 reverses, which drives the rotating shaft 32 to rotate through the transmission component 33, and then drives the rotating part 34 to rotate obliquely downward.

[0090] Furthermore, such as Figure 3As shown, the frame 1 of this application is designed to include a lower frame 11 and an upper frame 12.

[0091] The upper frame 12 is detachably mounted on top of the lower frame 11. Specifically, it can be fixed to the lower frame 11 with screws or other fasteners, without limitation.

[0092] like Figure 4 as well as Figure 6 As shown, the lower frame 11 has a first limiting part 111 at its top, and the upper frame 12 has a second limiting part 123 at its bottom. When the upper frame 12 is installed on the lower frame 11, a rotating cavity is formed between the first limiting part 111 and the second limiting part 123 for the rotating shaft 32 to rotate. Both the lower frame 11 and the upper frame 12 have clearance grooves 112 to allow the rotating component 34 to rotate. Similarly, when the lower frame 11 and the upper frame 12 are installed together, corresponding mounting cavities for the driver 31 and the transmission assembly 33 can also be formed, and there are no specific limitations.

[0093] Furthermore, regarding the design of the first limiting part 111, it can be a first recessed part into which the rotating shaft 32 is inserted, such as... Figure 4 As shown, it can be a semi-cylindrical groove that adapts to the length of the 32-inch rotating shaft.

[0094] The bottom of the upper frame 12 is provided with several ribs 122, and the second limiting part 123 is a second groove part opened at the bottom of the rib 122 for the rotating shaft to be inserted. The second groove part is an arc-shaped groove adapted to the curvature of the rotating shaft 32. In addition, the design of the ribs 122 can also enhance the structural strength of the upper frame 12.

[0095] The above design also allows a rotating cavity to be formed between the first groove and the second groove. The axial direction of the rotating shaft 32 can be limited by the transmission assembly 33 or by the end of the first groove; there is no specific limitation.

[0096] In this application, the frame 1 is designed as a combination of the upper frame 12 and the lower frame 11, which makes the installation and disassembly of the drive mechanism 3 more convenient and easier to maintain.

[0097] Furthermore, the rotating component 34 and the door bracket 35 are preferably designed to be detachably connected for easy maintenance. Specifically, for example... Figure 6 as well as Figure 7 As shown, a connecting shaft 341 is provided on the rotating component 34. The rotating component 34 may include two side plates arranged in parallel, with one end connected to the rotating shaft 32, a connecting plate provided between the two side plates, and the connecting shaft 341 connecting the other ends of the two side plates. The specific design can be varied according to actual needs and is not limited.

[0098] The door support 35 is provided with several slots 351 with a certain deformation, that is, the width of the slots 351 can be elastically varied within a certain range, which is conducive to connection and fit.

[0099] A limiting block 352 is also provided in the slot 351; the connecting shaft 341 is inserted into the slot 351 via the limiting block 352 and rotates with the slot 351.

[0100] The limiting block 352 is designed to prevent the connecting shaft 341 from loosening. During installation, pressing the connecting shaft 341 with a little force will allow the connecting shaft 341 to overcome the elastic force of the slot 351 and be inserted into the slot 351 by the limiting block 352. During disassembly, the connecting shaft 341 can be removed from the slot 351 with a little force, thus realizing the quick disassembly of the door bracket 35 and the rotating part 34.

[0101] The door bracket 35 also serves as a counterweight. After being connected to the door 2, when the door 2 rotates upward on the rotating part 34, the door 2 can more smoothly flip downward to a vertical position to open.

[0102] Furthermore, such as Figure 1 As shown, a handle 101 is provided on one side of the compartment 100 for easy access.

[0103] Furthermore, such as Figure 2 As shown, since the opening of the compartment 100 is generally designed to be small, it is difficult to remove the garbage bag from the opening when it is full of clumped garbage. In order to facilitate the removal of the garbage bag full of clumped garbage, this application also provides a notch 102 on the side of the compartment 100. The notch 102 can be set on the opposite side of the handle 101, and a removable sealing plate can be added to close the notch 102 when not in use. The specific details are not limited.

[0104] The waste collection chamber structure designed in this application opens the chamber door 2 when it needs to collect clumps, and closes it at other times. This achieves a sealed environment for the waste collection chamber most of the time without affecting its normal function, preventing odor from escaping and improving the user experience.

[0105] This application also discloses a cat toilet, including a base, a rotating drum, and the waste collection chamber structure of the above embodiment one or embodiment two.

[0106] Both the rotating drum and the waste collection chamber are mounted on the base. The waste collection chamber is used to collect the clumps separated from the rotating drum. The base is equipped with a rotating drum drive assembly to drive the rotating drum to rotate. The rotating drum drive assembly drives the rotating drum to rotate, thereby separating the cat litter and clumps inside. The clumps separated in the rotating drum fall into the chamber from the clump discharge port. In addition, for easy access, a handle on one side of the chamber is exposed on the base.

[0107] The above provides a detailed description of a feces collection chamber structure and a cat toilet provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
