[0039] Specifically, in combination Figure 2 and Figure 3As shown, the base 110 is provided with a first mounting groove 112 and a waste collection chamber 111, the waste collection chamber 111 being used to hold the packaging bag 200. The roller assembly 120 is mounted in the first mounting groove 112 and rotates relative to the base 110. A sand separator 121 is provided inside the roller assembly 120. A first opening 122 is provided on the side of the roller assembly 120 near the waste collection chamber 111. The sand separator 121 extends to the position of the first opening 122. The roller assembly 120 is connected to the waste collection chamber 111 through the first opening 122. During rotation, the roller assembly 120 can separate pet feces and cat litter through the sand separator 121. The pet feces are transported to the waste collection chamber 111 through the first opening 122, causing the pet feces to fall directly into the packaging bag 200 in the waste collection chamber 111.

[0040] In this embodiment, the packaging device 130 is provided corresponding to the feces collection chamber 111. The packaging device 130 includes a sealing assembly 131 and a cutting assembly 132. The cutting assembly 132 includes a heating element 1321 and a cutting element 1322. The heating element 1321 is connected to the cutting element 1322. The sealing assembly 131 moves relative to the cutting element 1322. The sealing assembly 131 can abut against or move away from the cutting element 1322. Accordingly, after collecting pet feces through the packaging bag 200, the sealing assembly 131 can be opened towards the... The cutting component 1322 moves, and the sealing component 131 is used to tighten the packaging bag 200. Since the packaging bag 200 has a roll structure, the heating element 1321 heats the cutting component 1322 to increase its temperature. The sealing component 131 drives the packaging bag 200 to abut against the cutting component 1322 to automatically cut the connection part of the packaging bag 200, so that the cutting component 1322 has a certain melting effect on the packaging bag 200, thereby improving the cutting efficiency of the packaging bag 200, reducing the need for users to tear the packaging bag 200 by hand, and facilitating the cleaning of pet feces.

[0041] Exemplary, such as Figure 3 As shown, the height of the first opening 122 of the roller assembly 120 is higher than the height of the waste collection chamber 111, so that pet waste can fall through the first opening 122 of the roller assembly 120 into the sealing bag 200 of the waste collection chamber 111 for collection.

[0042] It should be noted that the reference Figure 4 and Figure 5As shown, the litter box 100 has a first direction X and a second direction Y, wherein the first direction X and the second direction Y are perpendicular to each other. For example, the first direction X refers to the length direction of the litter box 100, and the second direction Y refers to the height direction of the litter box 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the various parts of the litter box 100 and should not be construed as limitations on this application.

[0043] In one embodiment, alternatively, referencing Figure 5 As shown, the sealing assembly 131 includes a driving member 1311, a movable member 1312, and a transmission screw 1313. The driving member 1311 is connected to the transmission screw 1313, and the movable member 1312 is movably connected to the transmission screw 1313. The driving member 1311 drives the movable member 1312 to move relative to each other along the first direction X through the transmission screw 1313. In other words, the transmission screw 1313 passes through the movable member 1312. The driving member 1311 drives the transmission screw 1313 to rotate, and the transmission screw 1313 moves relative to the movable member 1312, causing the movable member 1312 to move relative to each other along the length of the litter box 100. The movable member 1312 abuts against the cutting member 1322 to achieve the purpose of cutting the sealing bag 200, or the movable member 1312 can be separated from the cutting member 1322.

[0044] In one embodiment, alternatively, referencing Figure 3 and Figure 4 As shown, the litter box 100 also includes a cover plate 1112. The waste collection chamber 111 has a second opening 1111. The cover plate 1112 covers the second opening 1111 and is movably connected to the waste collection chamber 111. Pet feces in the roller assembly 120 can fall through the first opening 122 into the second opening 1111 of the waste collection chamber 111, facilitating the collection of pet feces in the waste collection chamber 111. The cover plate 1112 can open the second opening 1111 of the waste collection chamber 111 or close the second opening 1111 of the waste collection chamber 111, reducing the odor from the waste collection chamber 111 and improving the user experience.

[0045] In one embodiment, alternatively, referencing Figure 1As shown, the litter box 100 also includes a control unit and a first sensor. The first sensor is located at the bottom of the waste collection chamber 111. The control unit is electrically connected to the first sensor. The first sensor is used to detect the weight of the pet's feces. When the litter box is full, the sealing assembly 131 is controlled to tighten and seal the sealing bag 200, and the connection of the sealing bag 200 is cut off by the cutting assembly 132. Furthermore, the roller assembly 120 is provided with a third sensor, which is electrically connected to the control unit. The third sensor is used to detect whether a pet has entered the roller assembly 120.

[0046] For example, the control element is a controller, which may include an integrated circuit chip with signal processing capabilities. The controller described above can be a general-purpose processor, including a central processing unit (CPU), or a microcontroller, microcontroller unit (MCU), complex programmable logic device (CPLD), field-programmable gate array (FPGA), application-specific integrated circuit (ASNC), embedded ARM, etc. The first sensing element can be a weight sensor, and the third sensing element can be an infrared sensor or other types of sensors; no specific limitations are imposed here.

[0047] In summary, during rotation, the roller assembly 120 of the litter box 100 separates pet feces and cat litter through the separating member 121. The pet feces are conveyed through the first opening 122 to the collection chamber 111, where they fall directly into the sealing bag 200. After the pet feces are collected through the sealing bag 200, they can be moved towards the cutting member 1322 via the sealing assembly 131. The sealing assembly 131 is used to tighten the sealing bag 200. With a roll-type structure, the heating element 1321 heats the cutting element 1322 to increase its temperature. The sealing assembly 131 drives the sealing bag 200 to abut against the cutting element 1322 to automatically cut the connection part of the sealing bag 200. This allows the cutting element 1322 to have a certain melting effect on the sealing bag 200, thereby improving the cutting efficiency of the sealing bag 200, reducing the need for users to tear the sealing bag 200 by hand, facilitating the cleaning of pet feces, and improving the user experience.

[0048] refer to Figures 1 to 3 As shown, an embodiment of this application provides another cat litter box 100, including a base 110, a roller assembly 120, and a packing device 130.

[0049] Specifically, in combination Figure 2 and Figure 3As shown, the base 110 is provided with a first mounting groove 112 and a waste collection chamber 111, the waste collection chamber 111 being used to place the packaging bag 200. The roller assembly 120 is mounted in the first mounting groove 112 and rotates relative to the base 110. A sand separator 121 is provided inside the roller assembly 120. A first opening 122 is provided on the side of the roller assembly 120 near the waste collection chamber 111. The sand separator 121 extends to the position of the first opening 122. The roller assembly 120 is connected to the waste collection chamber 111 through the first opening 122. The packing device 130 is configured corresponding to the waste collection chamber 111. The packing device 130 includes a sealing assembly 131 and a cutting assembly 132. The cutting assembly 132 includes a heating element 1321 and a cutting element 1322. The heating element 1321 is connected to the cutting element 1322. The sealing assembly 131 moves relative to the cutting element 1322, and the sealing assembly 131 can abut against or move away from the cutting element 1322. Correspondingly, during the rotation of the roller assembly 120, the pet feces and cat litter can be separated by the litter separator 121. The pet feces are transported to the waste collection chamber 111 through the first opening 122, allowing the pet feces to fall directly into the waste collection chamber 111. Inside the packaging bag 200, after collecting pet feces through the packaging bag 200, it can move towards the cutting member 1322 via the sealing component 131. The sealing component 131 is used to tighten the packaging bag 200. Since the packaging bag 200 has a roll-type structure, the heating element 1321 heats the cutting member 1322 to increase its temperature. The sealing component 131 drives the packaging bag 200 to abut against the cutting member 1322 to automatically cut the connection part of the packaging bag 200, so that the cutting member 1322 has a certain melting effect on the packaging bag 200, thereby improving the cutting efficiency of the packaging bag 200, reducing the need for users to tear the packaging bag 200 by hand, and facilitating the cleaning of pet feces.

[0050] It should be noted that the reference Figure 4 and Figure 5 As shown, the litter box 100 has a first direction X and a second direction Y, wherein the first direction X and the second direction Y are perpendicular to each other. For example, the first direction X is taken as the length direction of the litter box 100, and the second direction Y is taken as the height direction of the litter box 100.

[0051] In one embodiment, alternatively, referencing Figure 5As shown, the sealing assembly 131 includes a driving member 1311, a movable member 1312, and a transmission screw 1313. The driving member 1311 is tractively connected to the transmission screw 1313, and the movable member 1312 is movably connected to the transmission screw 1313. The driving member 1311 drives the movable member 1312 to move relative to it along a first direction X via the transmission screw 1313. In other words, the transmission screw 1313 passes through the movable member 1312. The driving member 1311 drives the transmission screw 1313 to rotate, causing the transmission screw 1313 to move relative to the movable member 1312, thus causing the movable member 1312 to move relative to the length of the litter box 100. The movable member 1312 abuts against the cutting member 1322 to cut the sealing bag 200, or the movable member 1312 can be separated from the cutting member 1322. For example, the driving member 1311 is a drive motor.

[0052] Optionally, refer to Figures 5 to 7 As shown, the sealing assembly 131 also includes a guide rail 1314. One end of the movable member 1312 is movably connected to the transmission screw 1313, and the end of the movable member 1312 away from the transmission screw 1313 is connected to the guide rail 1314. The guide rail 1314 is arranged parallel to the transmission screw 1313. The opposite ends of the movable member 1312 are respectively connected to the transmission screw 1313 and the guide rail 1314. Since the guide rail 1314 and the transmission screw 1313 are parallel to each other, the transmission screw 1313 and the guide rail 1314 together guide the relative movement of the movable member 1312, preventing the movable member 1312 from deviating during movement and ensuring that the movable member 1312 moves along a preset path.

[0053] Furthermore, such as Figure 6 As shown, the guide rail 1314 is the first guide rail 1314a, which has a track groove. The movable member 1312 is equipped with a connecting wheel 1312a. The connecting wheel 1312a is engaged in the track groove of the first guide rail 1314a. The movable member 1312 is slidably connected to the track groove of the first guide rail 1314a through the connecting wheel 1312a, allowing the movable member 1312 to move relative to the litter box 100 along its length. Figure 7 As shown, the guide rail 1314 can also be a second guide rail 1314b, which is a guide rod. The movable member 1312 is sleeved on the guide rod, so that the movable member 1312 moves relative to the guide rod along the length direction of the litter box 100.

[0054] Optionally, refer to Figure 5As shown, the sealing assembly 131 further includes a first micro switch 1315 and a second micro switch 1316. The movable member 1312 has a first position and a second position. The first micro switch 1315 is disposed in the first position, and the second micro switch 1316 is disposed in the second position. It can be understood that the micro switches are used to detect mechanical movement and convert it into an electrical signal. The first micro switch 1315 and the second micro switch 1316 are used to trigger the detection signal. The detection signal determines whether the movement of the movable member 1312 is in place, thereby realizing the automated sealing operation of the packaging bag 200. When the movable member 1312 is in the first position, the movable member 1312 abuts against the cutting member 1322, and the movable member 1312 abuts against the first micro switch 1315. The first position is the final position where the movable member 1312 tightens and seals the packaging bag 200. When the movable part 1312 is in the second position, the movable part 1312 is away from the cut-off part 1322, and the movable part 1312 abuts against the second micro switch 1316. The second position is the initial position of the movable part 1312 in the unused state, so that the movable part 1312 can move relative to the initial position and the final position.

[0055] Optionally, refer to Figure 5 and Figure 8 As shown, the cutting assembly 132 includes a housing 1323 with a receiving groove. The heating element 1321 is disposed in the receiving groove. The cutting element 1322 contacts the heating element 1321 and closes the opening of the receiving groove. The cutting element 1322 has a blade portion 1322a on the side away from the heating element 1321, which corresponds to the movable part 1312. Accordingly, the heating element 1321 is installed in the receiving groove. The housing 1323 serves a protective function to prevent the heating element 1321 from overheating and affecting other components. The heating element 1321 contacts the cutting element 1322 and heats it, so that the blade portion 1322a of the cutting element 1322 can directly melt the cut when cutting the packaging bag 200, thereby improving the cutting efficiency.

[0056] In one embodiment, alternatively, referencing Figure 3 and Figure 4As shown, the litter box 100 also includes a cover plate 1112. The waste collection chamber 111 has a second opening 1111, and the cover plate 1112 covers the second opening 1111. The cover plate 1112 is movably connected to the waste collection chamber 111. Pet feces in the roller assembly 120 can fall through the first opening 122 into the second opening 1111 of the waste collection chamber 111, facilitating the collection of pet feces by the waste collection chamber 111. The cover plate 1112 can open or close the second opening 1111 of the waste collection chamber 111, reducing odor escape from the waste collection chamber 111 and improving the user experience. Furthermore, the cover plate 1112 is hinged to the second opening 1111 of the waste collection chamber 111. For example, the cover plate 1112 is provided with a second sensor, which can detect the position state of the cover plate 1112. The control unit can control the movement of the cover plate 1112 through the second sensor to open or close the second opening 1111 of the waste collection chamber 111.

[0057] Optionally, such as Figure 3 As shown, the centerline direction of the second opening 1111 is perpendicular to the centerline direction of the first opening 122. In other words, the opening direction of the second opening 1111 and the opening direction of the first opening 122 are perpendicular to each other and are in different directions. For example, the height of the second opening 1111 is greater than the height of the first opening 122. The pet feces fall through the second opening 1111 to the position of the first opening 122, and finally the pet feces enter the feces collection chamber 111.

[0058] In one embodiment, alternatively, referencing Figure 4 As shown, the waste collection chamber 111 is provided with an exhaust vent and a ventilation component 1113. The ventilation component 1113 is located at the exhaust vent and can create a negative pressure space in the waste collection chamber 111. The ventilation component 1113 is used to control the opening and closing of the exhaust vent. The ventilation component 1113 can also create a negative pressure space in the waste collection chamber 111, allowing the sealing bag 200 to be adsorbed to the bottom of the waste collection chamber 111. This allows the sealing bag 200 to automatically unfold to collect pet feces, increasing the coverage area of ​​the sealing bag 200 and reducing the amount of pet feces falling into uncovered areas.

[0059] In one embodiment, alternatively, referencing Figure 1As shown, the litter box 100 also includes a control unit and a first sensor. The first sensor is located at the bottom of the waste collection chamber 111. The control unit is electrically connected to the first sensor. The first sensor is used to detect the weight of the pet's feces. When the litter box is full, the sealing assembly 131 is controlled to tighten and seal the sealing bag 200, and the connection position of the sealing bag 200 is cut off by the cutting assembly 132. Further, the roller assembly 120 is provided with a third sensor, which is electrically connected to the control unit.
