Technical Field

[0002] The present application relates to the technical field of pet supplies, and in particular to a feces collection bin structure and a cat toilet, a door assembly and a feces collection bin, and a cat toilet feces collection bin and a cat toilet. Background Art

[0003] The introduction of cat litter boxes has eliminated the tedious and time-consuming task of shoveling poop for cat owners, improving the cat-keeping experience. The working principle of automatic cat litter boxes currently on the market is as follows: cat litter is placed in a rotating drum with a screen inside. When a cat defecates on the litter, the litter combines with the clumps to form a clumping mass. The rotating drum, in conjunction with the screen, separates the litter from the clumping mass and discharges the clumping mass into a collection bin.

[0004] However, the opening of the feces collection bin in the current automatic cat toilet equipment is mostly designed to be open all the time, which causes the feces to accumulate and smell to be emitted during use, affecting the user experience.

[0005] The introduction of cat litter boxes has significantly improved the cat owner's experience. The working principle of existing automatic cat litter boxes on the market is as follows: cat litter is placed in a rotating drum with a screen inside. When a cat defecates on the litter, the litter combines with the clumps to form a clumping mass. The rotating drum, in conjunction with the screen, separates the litter from the clumping mass and discharges the clumping mass into a collection bin.

[0006] Currently, the opening of the feces collection bin in most automatic cat toilets is always open. This causes the odor of feces to escape during use, affecting the user experience. To address this issue, some feces collection bins have doors installed on the opening to reduce the release of odor. However, most existing doors are directly installed on the opening, making them difficult to remove and cleaning.

[0007] The introduction of cat litter boxes has eliminated the tedious and time-consuming task of shoveling poop for cat owners, improving the cat-keeping experience. The working principle of automatic cat litter boxes currently on the market is as follows: cat litter is placed in a rotating drum with a screen inside. When a cat defecates on the litter, the litter combines with the clumps to form a clumping mass. The rotating drum, in conjunction with the screen, separates the litter from the clumping mass and discharges the clumping mass into a collection bin.

[0008] Since the storage bin has a limited capacity, it is necessary to check whether it is full in time so that the bin can be cleaned in time. To this end, the storage bin of existing automatic cat toilets is equipped with a detection device to detect whether it is full, but it can only detect whether it is full and cannot detect the remaining amount.

[0137] The following is a clear and complete description of the technical solutions of the embodiments of the present application, with reference to the accompanying drawings. It should be understood that the embodiments described are only a portion of the embodiments of the present application, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present application without inventive effort are also within the scope of protection of the embodiments of the present application.

Therefore, they should not be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0139] In the description of the embodiments of the present application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, replaceable connections, or integral connections. They can also refer to mechanical connections or electrical connections. They can also refer to direct connections or indirect connections through an intermediate medium. They can also refer to internal connections between two components. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0140] The embodiment of the present application discloses a feces collection bin structure.

[0141] Please refer to FIG1 , an embodiment of a feces collection bin structure provided in the present application includes:

[0142] The bin body 100 and the bin cover 200.

[0143] A receiving cavity for receiving the agglomerates is provided in the bin body 100 , and an opening communicating with the receiving cavity is provided at the top of the bin body 100 .

[0144] 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 close or open the opening. The bin cover 200 can be mounted directly on the opening, or the opening can be extended upward to form an extension channel, and the bin cover 200 is then mounted on the extension channel. There is no specific limitation.

[0145] The driving mechanism 3 is used to drive the door 2 to move so that the opening is closed or opened, ensuring that when the feces collecting bin is in use, the opening can be opened normally to allow the clumps to fall into it, and when not in use, the opening can be closed, so that the feces collecting bin is in a closed state most of the time, avoiding the odor in the feces collecting bin from being emitted and affecting the user experience.

[0146] The above is a first embodiment of a feces collection bin structure provided by the embodiment of the present application. The following is a second embodiment of a feces collection bin structure provided by the embodiment of the present application. Please refer to Figures 1 to 7 for details.

[0147] Based on the solution of the above embodiment 1:

[0148] Furthermore, as shown in FIG. 2 , the driving mechanism 3 includes a driver 31 and a rotating shaft 32 .

[0149] The driving end of the driver 31 is connected to the rotating shaft 32, which is used to drive the rotating shaft 32 to rotate, and the warehouse door 2 is connected to the rotating shaft 32. The driver 31 is a rotating motor that can rotate forward and reverse, which drives the rotating shaft 32 to rotate, thereby driving the warehouse door 2 to open and close the opening.

[0150] Furthermore, as shown in FIG2 , the driving end of the driver 31 can be connected to the rotating shaft 32 via a transmission assembly 33. The transmission assembly 33 can be a gear transmission structure, a pulley transmission structure, or the like, without specific limitation. Utilizing 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, the installation and removal of the rotating shaft 32 from the driver 31 are more convenient, facilitating maintenance. Of course, as desired, the driving end of the driver 31 can also be directly connected to one end of the rotating shaft 32, without specific limitation.

[0151] Furthermore, as shown in Figures 2, 4, and 7, whether the door 2 is fully opened or closed is usually detected by a Hall sensor, which inevitably results in some detection errors causing the door 2 to not be 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.

[0152] The driving end of the driver 31 is connected to the driving gear 331, driving the driving gear 331 to rotate. The driven gear 332 is elastically connected to the rotating shaft 32 via the elastic member 334. The driving gear 331 meshes with the driven gear 332 to drive the rotating shaft 32 to rotate. With this design, when the door 2 is opened or closed, the driven gear 332 drives the rotating shaft 32 to rotate via the elastic member 4. When the door 2 is fully closed, the driving gear 331 continues to rotate a certain angle. At this time, the position of the door 2 does not change, but the elastic member 334 is compressed or stretched, providing a spring force to keep the door 2 closed tightly.

[0153] As for the design of the driven gear 332 , it can be a full gear design. In the full gear design, a sensor can be additionally provided to detect the rotation angle of the driven gear 332 to avoid excessive compression or stretching of the elastic member 334 .

[0154] Of course, it can also be an incomplete gear design. For example, the driving gear 331 is meshed with the incomplete tooth portion 333 on the driven gear 332. When the driving gear 331 is meshed with a 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, the gear will slip and emit a sound similar to "clicking" to prompt that the warehouse door 2 is in place and is compressed by the elastic member 2. It can be seen that the use of an incomplete gear design can not only solve the problem of excessive compression or stretching of the elastic member 334, but also provide a prompt for the warehouse door 2 to be in place. Compared with the complete gear design, it has lower cost and better use effect. The span of the incomplete tooth portion 333 of the driven gear 332 can be set according to the actual need. The angle range is not specifically limited.

[0155] 7 , the elastic member 334 is preferably a torsion spring. The driven gear 332 is rotatably mounted on one end of the shaft 32 ; the elastic member 334 is sleeved on the shaft 32 , with one torque arm connected to the shaft 32 and the other torque arm connected to the driven gear 332 .

[0156] Furthermore, as shown in FIG1 , in order to facilitate the installation and arrangement of the driving mechanism 3 , the bin cover 200 further includes a frame 1 .

[0157] Frame 1 is mounted on the opening, with a central cavity formed in the middle that connects to the opening. Drive mechanism 3 is mounted on frame 1 and is used to drive door 2 to open or close the cavity. In other words, drive mechanism 3 controls the opening or closing of the cavity by driving door 2.

[0158] Furthermore, as shown in FIG3 , in order to facilitate the overlapping fit between the door 2 and the frame 1 , a step 121 that can contact and abut the door 2 is provided around one end of the through cavity away from the opening.

[0159] Furthermore, as shown in FIG. 2 and FIG. 3 , in terms of realizing the opening and closing control of the warehouse door 2 , the driving mechanism 3 may also be designed to include a rotating member 34 and a warehouse door bracket 35 .

[0160] A rotating member 34 is fixed to one side of the rotating shaft 32 and movably extends into the central cavity. A door bracket 35 is hingedly connected to the rotating member 34. The door 2 is mounted on the door bracket 35. It is understood that when the driver 31 drives the rotating member 34 upward by a certain angle via the rotating shaft 32, the door bracket 35 and the rotating member 34 are rotatably connected. Therefore, under the force of gravity of the door bracket 35 and the door 2, the door bracket 35 rotates relative to the rotating member 34, causing the door 2 to assume a vertical position, i.e., the door 2 is opened. When the driver 31 drives the rotating member 34 downward by a certain angle via the rotating shaft 32, the door bracket 35 rotates relative to the rotating member 34 due to the rotatable connection between the rotating member 34 and the door bracket 35, causing the door 2 to re-engage with the step 121, i.e., the door 2 is closed.

[0161] 5 , a roller 353 is pivotally connected to the door bracket 35 and is in rolling contact with the step 121. The provision of the roller 353 can make the cooperation between the door 2 and the step 121 smoother.

[0162] Furthermore, the door 2 and the door bracket 35 are detachably connected and cooperated, so as to facilitate cleaning or replacement of the door 2 .

[0163] Furthermore, as shown in FIG3 , the step 121 is tilted as a whole, so that the warehouse door 2 in the closed state is tilted. This design makes the opening and closing of the warehouse door 2 more convenient. Specifically, the top of the frame 1 can be tilted, so that the step 121 formed at the top edge of the central cavity of the frame 1 is also tilted as a whole. For example, if the step 121 is tilted downward along one side edge toward the other side edge, the rotating shaft 32 can be set at a position below one side edge of the step 121, and there is no specific limitation. Taking this as an example, when the warehouse door 2 needs to be opened, the driver 31 rotates, and the rotating shaft 32 is driven to rotate through the transmission assembly 33, and then the rotating member 34 is driven to rotate diagonally upward; when the warehouse door 2 needs to be closed, the driver 31 is reversed, and the rotating shaft 32 is driven to rotate through the transmission assembly 33, and then the rotating member 34 is driven to rotate diagonally downward.

[0164] Furthermore, as shown in FIG3 , the frame 1 of the present application is designed to include a lower frame 11 and an upper frame 12 .

[0165] The upper frame 12 is detachably mounted on the top of the lower frame 11 , and can be fixed to the lower frame 11 by fasteners such as screws, without limitation.

[0166] As shown in Figures 4 and 6 , a first stopper 111 is provided at the top of the lower frame 11, and a second stopper 123 is provided at the bottom of the upper frame 12. When the upper frame 12 is mounted on the lower frame 11, a rotation cavity is formed between the first stopper 111 and the second stopper 123, allowing the rotation of the rotating shaft 32. Both the lower frame 11 and the upper frame 12 are provided with a clearance groove 112 to prevent rotation of the rotating member 34. Similarly, when the lower frame 11 and the upper frame 12 are mounted together, corresponding installation cavities for the driver 31 and the transmission assembly 33 are also formed, without further limitation.

[0167] Furthermore, as for the design of the first limiting portion 111 , it can be a first groove portion for the rotating shaft 32 to be inserted into. As shown in FIG. 4 , the first groove portion can be a semi-cylindrical groove adapted to the length of the rotating shaft 32 .

[0168] The bottom of the upper frame 12 is provided with a plurality of ribs 122. The second stopper 123 is a second groove portion provided at the bottom of the ribs 122 for the rotation shaft to be inserted into. The second groove portion is an arc-shaped groove adapted to the curvature of the rotation shaft 32. In addition, the design of the ribs 122 can also enhance the structural strength of the upper frame 12.

[0169] The above design also allows a rotation cavity to be formed between the first groove portion and the second groove portion. The axial direction of the rotating shaft 32 can be limited by the transmission assembly 33 or by the end of the first groove portion, without any specific limitation.

[0170] In the present application, the frame 1 is designed to be a combination of an upper frame 12 and a lower frame 11, so that the installation and disassembly of the driving mechanism 3 is more convenient and facilitates maintenance.

[0171] Furthermore, the rotating member 34 and the door bracket 35 are preferably designed to be detachably connected to facilitate maintenance. Specifically, as shown in Figures 6 and 7, a connecting shaft 341 is provided on the rotating member 34. The rotating member 34 may include two side panels arranged in parallel, one end of which is connected to the rotating shaft 32, and a connecting plate disposed between the two side panels, with the connecting shaft 341 connected between the other ends of the two side panels. The specific design can be varied according to actual needs and is not limited.

[0172] The door bracket 35 is provided with a plurality of slots 351 with a certain deformation amount, that is, the width of the slots 351 can be elastically changed within a certain range, which is conducive to connection and matching.

[0173] A limiting block 352 is further provided in the slot 351 ; the connecting shaft 341 is inserted into the slot 351 via the limiting block 352 and rotates in conjunction with the slot 351 .

[0174] The setting of the limit block 352 is used to prevent the connecting shaft 341 from loosening. During installation, the connecting shaft 341 can be pressed with a little force to make the connecting shaft 341 overcome the elastic force of the slot 351 and thus be inserted into the slot 351 through the limit block 352; during disassembly, the connecting shaft 341 can be taken out of the slot 351 with a little force, thereby realizing the rapid disassembly of the warehouse door bracket 35 and the rotating part 34.

[0175] The door bracket 35 also plays a certain role of counterweight. After being connected to the door 2, when the door 2 rotates upward on the rotating member 34, the door 2 can be turned downward more smoothly to a vertical state to be opened.

[0176] Furthermore, as shown in FIG1 , a handle 101 is provided on one side of the bin body 100 for easy taking.

[0177] Furthermore, as shown in FIG2 , since the opening of the bin body 100 is generally designed to be smaller, when the internal garbage bag is full of clumped garbage, it is difficult to remove it from the opening. In order to facilitate the removal of the garbage bag full of clumped garbage, the present application also provides a notch 102 on the side of the bin body 100. The notch 102 can be specifically provided on the opposite side of the handle 101, and a detachable sealing plate can be additionally provided to close the notch 102 when not in use, without any specific limitation.

[0178] The feces collection bin structure designed in this application opens the bin door 2 when it is necessary to receive agglomerated feces, and closes the bin door 2 at other times. In this way, the feces collection bin is sealed most of the time without affecting the normal function of the feces collection bin, thus avoiding the release of odor in the feces collection bin and improving the user experience.

[0179] The present application also discloses a cat litter box, comprising a base, a rotating drum, and the feces collection bin structure of the above-mentioned embodiment 1 or embodiment 2.

[0180] The drum and the feces collection bin structure are both installed on the base; the feces collection bin structure is used to collect the clumps separated from the drum, and the base is provided with a drum drive assembly for driving the drum to rotate. The drum drive assembly drives the drum to rotate to separate the cat litter and clumps inside. The clumps separated in the drum fall into the bin body from the clumping outlet; in addition, in order to facilitate taking out, the handle on one side of the bin body is exposed on the base.

[0181] The above is a detailed introduction to the feces collection bin structure and cat toilet provided by this application. For those skilled in the art, based on the ideas of the embodiments of this application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on this application.

[0182] An embodiment of the present application discloses a door assembly.

[0183] Referring to FIG. 8 and FIG. 10 , an embodiment of a door assembly provided in the embodiments of the present application includes:

[0184] The door 100 and the door support 200 .

[0185] The door 100 is provided with a first plug-in portion 11 , and the door bracket 200 is provided with a second plug-in portion 21 that plugs and cooperates with the first plug-in portion 11 .

[0186] The door 100 is also provided with a first locking portion 12, and the door bracket 200 is also provided with a second locking portion 22 that can be locked and matched with the first locking portion 12; when the first plug-in portion 11 and the second plug-in portion 21 are plugged and matched in place, the first locking portion 12 and the second locking portion 22 are locked and matched.

[0187] The door assembly designed in the present application adds a door bracket 200, which uses the plug-in cooperation between the first plug-in part 11 and the second plug-in part 21, and then uses the locking cooperation between the first locking part 12 and the second locking part 22 to lock the connection between the door 100 and the door bracket 200. When the first plug-in part 11 and the second plug-in part 21 are connected in place, the first locking part 12 and the second locking part 22 can be used to lock the door, thereby realizing a quick connection between the door bracket 200 and the door 100; and when the door 100 needs to be disassembled, the door 100 can be quickly removed by unlocking the connection between the first locking part 12 and the second locking part 22, thereby improving the convenience of cleaning the door 100.

[0188] The above is Example 1 of a door assembly provided in an embodiment of the present application. The following is Example 2 of a door assembly provided in an embodiment of the present application. Please refer to Figures 8 to 11 for details.

[0189] Based on the solution of the above embodiment 1:

[0190] Furthermore, as shown in Figures 8 to 10, in terms of the plug-in matching method, the second plug-in portion 21 can be designed as a female plug structure for the first plug-in portion 11 as a male plug structure to be movably inserted. It can be understood that the second plug-in portion 21 is a slot structure. Taking this as an example, the second locking portion 22 can be arranged in the second plug-in portion 21.

[0191] Correspondingly, the first plug-in portion 11 is provided with an escape groove 111 for the insertion of the second locking portion 22. The first locking portion 12 is disposed in the escape groove 111 to facilitate locking engagement with the second locking portion 22. Centrally arranging the first locking portion 12 and the first plug-in portion 11, and the second locking portion 22 and the second plug-in portion 21, can further optimize the structure and make the overall structure more compact.

[0192] Of course, the above embodiment can also be designed in reverse, that is, the second plug-in portion 21 serves as a male plug structure, and the first plug-in portion 11 serves as a female plug structure for the second plug-in portion 21 to be inserted into. The first locking portion 12 is correspondingly disposed in the first plug-in portion 11, and the second plug-in portion 21 is provided with a relief groove 111 for the first locking portion 12 to be inserted into, and the second locking portion 22 is disposed in the plug-in portion. Those skilled in the art can make appropriate variations based on this design without limitation.

[0193] Furthermore, the second plug-in portion 21 can be a U-shaped groove structure, and correspondingly, the first plug-in portion 11 is a U-shaped frame structure. The first plug-in portion 11 is a U-shaped frame structure design, which can not only serve as a male plug structure, but also form a corresponding avoidance groove 111 for the second locking portion 22 to be inserted. Of course, it can also be a structure of other shapes, which can meet the above-mentioned plug-in matching requirements while realizing the locking matching between the first locking portion 12 and the second locking portion 22.

[0194] Furthermore, in order to facilitate locking or unlocking between the first locking portion 12 and the second locking portion 22 , the first locking portion 12 and the second locking portion 22 may be designed to be in a snap-fit ​​connection.

[0195] Furthermore, as shown in Figures 9 to 11, taking a snap-on connection as an example, the first locking portion 12 can be designed as a slot, and the second locking portion 22 can be designed as a snap-on with a certain elastic deformation. The end of the snap-on away from the door bracket 200 is provided with a protrusion that can be snapped into the slot. The second locking portion 22 can be integrally formed with the door bracket 200. The elastic deformation design can utilize elastic force when the protrusion of the second locking portion 22 is snapped into the first locking portion 12, so that the protrusion can achieve displacement changes when subjected to a certain external force, thereby facilitating the locking and cooperation with the first locking portion 12. When unlocking, the snap-on is deformed by external force so that the protrusion is disengaged from the first locking portion 12 to complete the unlocking, which is also convenient.

[0196] Furthermore, as shown in FIG9 , an annular flange 13 may be provided at the bottom of the door 100 , and a slot may be formed between the annular flange 13 and the bottom of the door 100 .

[0197] A first guide portion 131 is provided on the outer side of the annular flange 13 to guide the protrusion to slide into the slot, and a second guide portion 132 is provided on the inner side of the annular flange 13 to guide the protrusion to slide out of the slot.

[0198] When the first plug-in portion 11 and the second plug-in portion 21 are plugged into place, the protrusion passes through the first guide portion 131 and the second guide portion 132 and enters the slot. When the protrusion passes through the first guide portion 131, it moves away from the door 100, causing the second locking portion 22 to deform. When it passes through the second guide portion 132, it recovers its deformation, allowing it to fit tightly into the slot. When unlocking is required, a force is applied to separate the first plug-in portion 11 and the second plug-in portion 21, causing them to move in the separation direction. During this process, the protrusion passes through the second guide portion 132 and the first guide portion 131 and slides out of the slot, thereby completing the unlocking process.

[0199] In this design, the first guide portion 131 facilitates the protrusion to slide into the slot, thereby improving the convenience of locking, while the second guide portion 132 facilitates the protrusion to slide out of the slot, thereby improving the convenience of unlocking.

[0200] In the present application, only the first guide portion 131 or only the second guide portion 132 may be designed. The specific selection may be varied according to actual needs without limitation.

[0201] In the present application, the first guide portion 131 and the second guide portion 132 may be inclined ribs connecting the side surface of the card slot and the bottom of the door 100 , and there is no specific limitation thereto.

[0202] Furthermore, as shown in FIG. 9 to FIG. 11 , the first plug-in portion 11 is provided with a limiting groove 112 along the plug-in matching direction with the second plug-in portion 21 .

[0203] One end of the retaining groove 112 extends from the first plug-in portion 11, while the other end is closed. The second plug-in portion 21 is provided with a retaining edge 211 that flexibly inserts into the retaining groove 112 through one end of the retaining groove 112. The coordinated design of the retaining groove 112 and the retaining edge 211 further enhances the secure connection between the first plug-in portion 11 and the second plug-in portion 21, thereby improving the reliability of the interlocking between the doors 100.

[0204] Furthermore, as shown in FIG11 , the limiting grooves 112 may be designed to be two, respectively provided on the two side surfaces of the first plug-in portion 11 ; correspondingly, the limiting edges 211 are also designed to be two, corresponding one to one with the limiting grooves 112 .

[0205] Furthermore, as shown in FIG8 , in order to improve the strength of the door bracket 200 , a plurality of reinforcing ribs 23 may be provided on the door bracket 200 .

[0206] As shown in FIG12 , the present application further discloses a feces collection bin, comprising a bin body 300 and the door assembly of the above-mentioned embodiment 1 or embodiment 2.

[0207] An opening 31 is provided on the warehouse body 300 , and the door assembly is installed on the opening 31 . The warehouse door 100 of the door assembly is connected to the warehouse body 300 via a warehouse door bracket 200 .

[0208] As for the connection design between the warehouse door bracket 200 and the warehouse body 300, the warehouse door bracket 200 can be directly hinged to the warehouse body 300, or can be hinged to the warehouse body 300 through a rotating member 4.

[0209] Taking the connection method of the rotating part 4 as an example, one end of the rotating part 4 is hinged to the warehouse body 300, and the other end is hinged to the warehouse door bracket 200. A driving mechanism can be used to drive the rotating part 4 to rotate, thereby driving the warehouse door 100 to open and close. A step 32 that contacts and abuts the warehouse door 100 can be set on the opening 31, so that the warehouse door 100 can better cover the opening 31.

[0210] The above is a detailed introduction to a door assembly and a feces collection bin provided by the present application. For a person skilled in the art, according to the ideas of the embodiments of the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.

[0211] The embodiment of the present application discloses a cat litter box.

[0212] Please refer to FIG13 , an embodiment of a cat litter box provided in the present application includes:

[0213] The feces collecting bin body 1 and the remaining amount detection device 2.

[0214] The feces collecting bin body 1 is provided with a receiving cavity for collecting agglomerates, and the residual amount detecting device 2 is used for detecting the residual amount in the receiving cavity.

[0215] The above design uses the remaining amount detection device 2 to detect the remaining amount of the storage chamber in the feces collection bin body 1, thereby providing the feces collection bin with a remaining amount detection function. Compared with the existing method that can only detect whether it is full, it is convenient for the owner to understand the remaining amount of the storage chamber of the feces collection bin body 1 in real time, so that the feces collection bin body 1 can be cleaned in advance according to the remaining amount, avoiding overflow, and providing a better user experience.

[0216] The above is Example 1 of a cat litter box and feces collection bin provided in an embodiment of the present application. The following is Example 2 of a cat litter box and feces collection bin provided in an embodiment of the present application. Please refer to Figures 13 to 15 for details.

[0217] Based on the solution of the above embodiment 1:

[0218] Furthermore, as shown in FIG15 , the design of the remaining amount detection device 2 includes a detection sensor and a processor.

[0219] The detection sensor 23 detects the agglomeration in the accommodation cavity and obtains information.

[0220] The processor 22 is electrically connected to the detection sensor 23 and analyzes and processes the acquired information to obtain the remaining volume of the accommodation cavity. The processor can be a PLC processor (PLC control board), a microprocessor, etc., and is not specifically limited.

[0221] Furthermore, the detection sensor 23 may be a distance measuring sensor for measuring the distance between itself and the agglomerates in the accommodation chamber.

[0222] Correspondingly, the processor 22 is used to compare and analyze the measured distance with the preset distance to obtain the remaining space of the accommodating cavity. In other words, the processor is used to process the distance measurement result and determine the remaining space of the accommodating cavity.

[0223] Furthermore, taking a distance measuring sensor as an example, the detection sensor may be a TOF sensor, an infrared sensor, a laser sensor, an ultrasonic sensor or a radar sensor.

[0224] Taking the application of a TOF sensor as an example, the TOF sensor points toward the cluster within the cavity and emits infrared light or laser light toward the cluster. The light is reflected by the cluster and returns to the TOF sensor. The distance between the cluster and the TOF sensor can be measured based on the time difference between the emission of the light and the light's return to the sensor after being reflected by the object. The cavity margin corresponding to the preset distance itself can be obtained through experimentation. Similarly, the relationship between the numerical change in the preset distance and the change in the cavity margin can also be summarized through experimentation. Therefore, the processor 22 compares the measured distance with the preset distance, determines the difference between the measured distance and the preset distance, and substitutes the difference between the measured distance and the preset distance into the relationship between the numerical change in the preset distance and the change in the cavity margin to obtain the cavity margin. The details will not be elaborated here.

[0225] Furthermore, the detection sensor 23 may also be an image sensor for acquiring image information of the agglomeration within the storage chamber; accordingly, the processor 22 is configured to analyze and process the acquired image information to determine the remaining amount of the storage chamber. More specifically, the processor 22 compares the acquired image information of the agglomeration within the storage chamber with images of various feces collection bin remaining amounts pre-stored in an image library. The image with the highest degree of match is then used as the current feces collection bin remaining amount.

[0226] Furthermore, since the shapes of the agglomerates are irregular, that is, the agglomerates are not stacked evenly in the collection bin, it is preferable to design a plurality of detection sensors 23, which are spaced apart from each other. By combining the detection data of multiple detection sensors 23 to determine the remaining capacity of the storage chamber, detection errors caused by the uneven stacking of agglomerates in the collection bin can be avoided, making the determination more accurate.

[0227] Furthermore, the structure of the feces collection bin 1 comprises a bin body 11 and a bin lid 12. The bin body 11 defines a storage chamber, and the top of the bin body 11 defines an opening that communicates with the storage chamber. The bin lid 12 is mounted directly above the opening and includes a bin door 121 that corresponds to the opening and can be opened and closed. When the bin door 121 is open, separated clumps can fall into it. When the bin door 121 is closed, the odor of the clumps in the storage chamber is prevented from escaping, improving the user experience.

[0228] As for the arrangement position of the detection sensor, it can be installed on the bin cover 12, or on the bin door 121, or on the top of the storage chamber. Of course, it can also be installed at the position corresponding to the opening above the bin cover 12, as shown in Figures 13 and 14, that is, installed on the outside of the feces collection bin body 1. In order to facilitate installation and fixation at an external position, the residual detection device 2 also includes a device shell 21, which is used to provide a fixed installation position for the processor 22 and the detection sensor 23. At the same time, it can cooperate with other structures of the cat toilet to achieve a fixed setting. The device shell 21 can be designed to include an upper shell 211 and a lower shell 212 detachably connected to the upper shell 211. As shown in Figure 15, the processor 22 can be fixed between the upper shell 211 and the lower shell 212, and the detection sensor 23 can be fixed on the processor 22, and the inside of the storage chamber can be detected through the corresponding detection avoidance hole on the lower shell 212. Those skilled in the art can make variations based on this design, and there is no specific limitation.

[0229] Furthermore, in order to facilitate taking and placing, a handle (not shown) is connected to one side of the bin body 11. The handle can be a notch for convenient hand grasping, or a U-shaped handle structure.

[0230] Furthermore, the processor 22 is also electrically connected to a display screen (not shown); the processor 22 is also used to display the remaining information obtained on the display screen. Of course, it can also be displayed through an APP on a mobile terminal such as a mobile phone, without limitation.

[0231] Furthermore, in order to remind the owner more promptly, the processor 22 is also electrically connected to an alarm (not shown in the figure); the processor 22 is also used to drive the alarm to send an alarm signal when it detects that the remaining volume of the accommodating cavity is lower than the warning value. The alarm can be a buzzer alarm or an audible and visual alarm.

[0232] The present application also discloses a cat litter box, comprising a base (not shown in the figure), a rotating drum (not shown in the figure), and the cat litter box collecting bin of the above-mentioned embodiment 1 or embodiment 2.

[0233] The feces collecting bin body 1 and the rotating drum of the cat toilet are installed on a base; a driving mechanism for driving the rotating drum to rotate is provided on the base; the feces collecting bin body 1 is used to collect the clumps separated from the rotating drum.

[0234] As shown in Figures 13 and 14, taking the cat litter box feces collection bin remaining detection device 2 installed on the outside and above the collection bin body 1, and its detection sensor 23 is a TOF sensor as an example, then when the bin door 121 is opened, the TOF sensor can emit infrared light or laser to irradiate the clumps in the accommodating cavity.

[0235] In addition, the handle connected to one side of the bin body 11 is preferably exposed on the base to facilitate taking it out.

[0236] The above is a detailed introduction to a cat litter box and a cat litter box provided in this application. For those skilled in the art, according to the ideas of the embodiments of this application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting this application.
