[0032] Reference Figures 1 to 3According to an example of the utility model, a cat litter box with a rolling bin that is easy to disassemble and assemble comprises a base 100, two pressure covers 210 and a rolling bin 300. The base 100 has two mounting walls 110 that are arranged opposite to each other. The mounting wall 110 is provided with a mounting surface 111 and a receiving groove 112. The side wall of the receiving groove 112 is provided with a guide limiting groove 113. The entrance of the guide limiting groove 113 and the entrance of the receiving groove 112 are both located on the mounting surface 111. The guide limiting groove 113 faces the receiving groove 112. The side wall inside the groove 112 is provided with a plug hole 114; the two glands 210 are respectively abutted against the two mounting surfaces 111, and a first mounting hole 01 is provided between the glands 210 and the corresponding mounting wall 110. The glands 210 are locked to the corresponding mounting wall 110 by a locking structure. The locking structure includes a limit plate 230 and an operating plate 220 connected to the gland 210. The limit plate 230 is rotatably mounted on the operating plate 220 through a first rotating shaft 231. The operating plate 220 Located in the corresponding accommodating groove 112, the limiting plate 230 is provided with a plug 232, and the plug 232 is inserted in the corresponding guide limiting groove 113 and the corresponding insertion hole 114, and at least one of the side walls of the plug 232 and the insertion hole 114 is elastic, and the first rotating shaft 231, the corresponding plug 232 and the corresponding entrance of the guide limiting groove 113 are distributed in a triangle, and the inner wall of the guide limiting groove 113 can abut against and block the plug 232 from popping out of the corresponding insertion hole 114, wherein the operating plate 220 is elastic or can rotate relative to the pressure cover 210, when the operating plate 220 drives the first rotating shaft 231 to move to the position where the first rotating shaft 231, the plug 232 and the corresponding entrance of the guide limiting groove 113 are distributed in a straight line, the inner wall of the guide limiting groove 113 releases the restriction on the corresponding plug 232; the rolling bin 300, the second rotating shafts 310 are provided at the opposite ends, and the two second rotating shafts 310 are rotatably installed in the two first mounting holes 01 one by one.

[0033] Reference Figure 3According to the principle of mechanics, the tension F0 applied to the gland 210 eventually forms a thrust F1 directed from the first shaft 231 to the plug post 232 and a rotational force F2 perpendicular to the limit plate 230 on the limit plate 230. When the first shaft 231, the corresponding plug post 232 and the corresponding entrance of the guide limit groove 113 are distributed in a triangular shape, the thrust F1 points to an inner wall of the guide limit groove 113. At this time, in addition to the abutment between the insertion hole 114 and the plug post 232, the inner wall of the guide limit groove 113 also abuts against the plug post 232. Under the obstruction of the inner wall of the guide limit groove 113, , the pin 232 is difficult to pop out from the corresponding socket 114. When the first rotating shaft 231, the corresponding pin 232 and the corresponding entrance of the guide limit groove 113 are distributed in a straight line, the thrust F1 points to the entrance of the guide limit groove 113, so that the inner wall of the guide limit groove 113 will not abut against and block the pin 232. Only the inner wall of the socket 114 blocks the pin 232, and at least one of the side wall of the socket 114 and the pin 232 is elastic. At this time, only a smaller thrust F1 is needed to make the pin 232 pop out from the socket 114 and the guide limit groove 113.

[0034] The cat litter box provided by the utility model utilizes the pressure cover 210 and the corresponding installation wall 110 to cooperate with each other to rotatably install the corresponding second rotating shaft 310 of the rolling bin 300 in the corresponding first installation hole 01, thereby, the rolling bin 300 can be disassembled and assembled by disassembling and assembling the two pressure covers 210, wherein, when installing the pressure cover 210, it is only necessary to place the pressure cover 210 on the installation surface 111 and insert the operating plate 220 into the receiving groove 112. Since at least one of the side walls of the plug post 232 and the insertion hole 114 is elastic, the plug post 232 on the limit plate 230 can be inserted into the insertion hole 114 under the guidance of the guide limit groove 113 during this process. At this time, since the first rotating shaft 231, the corresponding plug post 232 and the corresponding entrance of the guide limit groove 113 are distributed in a triangle, The inner wall of the guide limit groove 113 abuts against and blocks the plug post 232 from popping out of the corresponding insertion hole 114, thereby locking the corresponding pressure cover 210 on the corresponding mounting wall 110. When the pressure cover 210 needs to be removed, it is only necessary to operate the operating panel 220 and pull the pressure cover 210. During this process, the operating panel 220 can drive the first rotating shaft 231 to move to a position where the first rotating shaft 231, the plug post 232 and the corresponding entrance of the guide limit groove 113 are linearly distributed, so that the inner wall of the guide limit groove 113 releases the restriction on the corresponding plug post 232, thereby when the pressure cover 210 is pulled, the plug post 232 can automatically pop out from the insertion hole 114 and the guide limit groove 113. Through the above-mentioned arrangement, the pressure cover 210 is convenient and simple to disassemble and assemble, thereby making the rolling bin 300 convenient and simple to disassemble and assemble.

[0035] Reference Figure 1 , Figure 4 and Figure 5According to some examples of the present invention, the mounting surface 111 is located on the upper surface of the corresponding mounting wall 110, the accommodating groove 112 and the guide limit groove 113 are both extended from top to bottom, the accommodating groove 112 is opened on the side of the corresponding mounting wall 110 away from the rolling bin 300, and the first rotating shaft 231 is located on the side of the corresponding guide limit groove 113 close to the rolling bin 300. Therefore, when removing the pressure cover 210, the user's hand can grasp the lower end of the operating panel 220 and pull up. During the pulling process, the operating panel 220 will drive the first rotating shaft 231 to move away from the rolling bin 300, thereby making the first rotating shaft 231, the plug column 232 and the corresponding entrance of the guide limit groove 113 distributed in a straight line, and then during the pulling process, the plug column 232 can automatically pop out of the socket 114 and the guide limit groove 113, thereby completing the disassembly of the pressure cover 210, and the disassembly of the pressure cover 210 is relatively convenient.

[0036] It is conceivable that, in other examples, the first rotating shaft 231 can also be set on the side of the corresponding guide limit groove 113 away from the rolling bin 300. Therefore, when removing the pressure cover 210, the user's hand needs to press the lower end of the operating panel 220 and pull up the pressure cover 210 at the same time. During this process, the operating panel 220 is compressed and drives the first rotating shaft 231 to rotate in the direction close to the rolling bin 300, thereby making the first rotating shaft 231, the plug column 232 and the corresponding entrance of the guide limit groove 113 distributed in a straight line, so that when the pressure cover 210 is pulled up, the plug column 232 can automatically pop out of the socket 114 and the guide limit groove 113, thereby successfully completing the removal of the pressure cover 210.

[0037] Reference Figure 3 , Figure 4 and Figure 6 According to some examples of the present invention, the first mounting hole 01 includes a first mounting groove 115 and a second mounting groove 211. The first mounting groove 115 is arranged on the corresponding mounting surface 111, and the second mounting groove 211 is arranged on the corresponding pressure cover 210. Therefore, during the installation of the rolling bin 300, the two second rotating shafts 310 of the rolling bin 300 can be placed one by one from top to bottom into the two first mounting grooves 115, and then the two pressure covers 210 are installed to complete the installation of the rolling bin 300. When disassembling the rolling bin 300, the two pressure covers 210 can be disassembled first, and then the rolling bin 300 can be separated from the base 100. Therefore, when disassembling the pressure covers 210, there is no need to take and place the rolling bin 300, and the disassembly and assembly is more convenient and labor-saving.

[0038] It should be noted that the first mounting hole 01 may also be arranged in other ways. For example, in some examples, the first mounting hole 01 includes a U-shaped hole arranged on the mounting surface 111, and the pressure cover 210 is used to close the entrance at the upper end of the U-shaped hole. Therefore, the pressure cover 210 cooperates with the corresponding mounting wall 110 to realize the installation of the second rotating shaft 310.

[0039] Reference Figure 1 , Figure 4 According to some examples of the present invention, the mounting wall 110 is provided with a guide portion 120, and the guide portion 120 is located on one side of the corresponding mounting surface 111. One of the guide portion 120 and the corresponding pressure cover 210 is provided with a guide groove 212, and the other is provided with a guide protrusion 121. The guide protrusion 121 can be slidably inserted in the guide groove 212 up and down. Therefore, during the installation of the pressure cover 210, the guide protrusion 121 and the guide groove 212 can cooperate with each other to guide the pressure cover 210 to be accurately installed on the corresponding mounting wall 110, ensuring that the plug column 232 on the limit plate 230 can accurately enter the corresponding socket 114. In addition, the cooperation between the guide protrusion 121 and the guide groove 212 can also play a positioning role to prevent the pressure cover 210 from shaking relative to the mounting wall 110.

[0040] Reference Figures 4 to 6 According to some examples of the present invention, one of the pressure cover 210 and the corresponding mounting surface 111 is provided with a positioning groove 213, and the other is provided with a positioning protrusion 116. The positioning groove 213 is inserted into the positioning protrusion 116. Through the cooperation between the positioning protrusion 116 and the positioning groove 213, the pressure cover 210 can be positioned to prevent the pressure cover 210 from deviating along the mounting surface 111.

[0041] Reference Figure 2 , Figure 4 According to some examples of the utility model, the base 100 is provided with a first driving device 400, and the output shaft of the first driving device 400 is installed with a driving gear 410. A driven gear structure 360 ​​is provided on the rolling bin 300, and the driven gear structure 360 ​​is detachably engaged with the driving gear 410 for transmission. With the above arrangement, during the installation of the rolling bin 300, the rolling bin 300 is placed on the base 100, so that the driving gear 410 and the driven gear structure 360 ​​can be easily engaged with each other. When disassembling the rolling bin 300, the driving gear and the driven gear structure 360 ​​will not cause obstacles, and the rolling bin 300 can be directly removed.

[0042] Reference Figure 1 , Figure 4 and Figure 7 According to some examples of the utility model, the rolling bin 300 has an inner cavity 320, the rolling bin 300 is provided with an opening 321 connected to the inner cavity 320, the rear side wall of the inner cavity 320 is provided with a cat litter holding chamber 330, the lower end of the cat litter holding chamber 330 is provided with a filter port 331 connected to the inner cavity 320, the filter port 331 is installed with a cat litter filter 340, the base 100 is provided with a discharge hole 130, the discharge hole 130 is located below the rolling bin 300, and the base 100 is installed with a feces collection bin 500 below the discharge hole 130. With the above arrangement, according to Figure 3When the rolling bin 300 is rotated in the direction indicated by the middle arrow, the cat feces can be separated from the cat litter by the cat litter filter 340, and the separated cat litter enters the cat litter holding chamber 330, and the separated cat feces passes through the outer wall of the cat litter holding chamber 330. When the opening 321 of the rolling bin 300 is facing the discharge hole 130, the pet cat feces can fall from the inner cavity 320 through the opening 321 to the discharge hole 130, and finally enter the feces collecting bin 500. After the feces are discharged, the rolling bin 300 rotates in the opposite direction to reset. At this time, the cat litter in the cat litter holding chamber 330 returns to the bottom of the rolling bin 300 from the cat litter filter 340. After the feces collecting bin 500 collects a certain amount of feces, the user can pour out the feces in the feces collecting bin 500.

[0043] Reference Figure 4 and Figure 7 According to some examples of the present invention, a cat litter bag 350 for holding cat litter is detachably mounted on the bottom wall of the inner cavity 320, and the cat litter bag 350 can be disassembled to facilitate cleaning of the cat litter bag 350 later.

[0044] Reference Figure 7 In the specific process, the rolling bin 300 includes an outer shell 300a and an inner cover 300b. The inner cavity 320 is located in the outer shell 300a. The second rotating shaft 310 and the driven gear structure 360 ​​are integrally formed with the outer shell 300a. The inner cover 300b is installed in the outer shell 300a. The inner cover 300b and the outer shell 300a are enclosed to form a cat litter containing cavity 330.

[0045] Reference Figure 2 , Figure 4 and Figure 8 According to some examples of the utility model, the feces collection bin 500 can be pulled out and installed on the base 100 through the guide rail structure 600. The feces collection bin 500 can be used to place a garbage bag, which is used to collect and store feces. With the above arrangement, when the feces needs to be thrown away, the feces collection bin 500 can be pulled out, and then the garbage bag can be taken out and thrown away.

[0046] Reference Figure 2 , Figure 4 and Figure 7 In some examples, a door panel 700 is slidably disposed in the base 100, and a second driving device is disposed in the base 100. The second driving device is electrically connected to the main control circuit board of the cat litter box, and the second driving device can drive the door panel 700 to open and close the discharge hole 130. Therefore, when it is necessary to discharge the feces in the rolling bin 300 into the feces collecting bin 500, the second driving device drives the door panel 700 to slide to open the discharge hole 130. After the feces are discharged, the second driving device drives the door panel 700 to close the discharge hole 130 to reduce the odor leakage in the feces collecting bin 500.

[0047] Reference Figure 4 , Figure 8 and Fig. 9 According to some examples of the utility model, the bottom of the base 100 is provided with a plurality of embedding holes 140, and the embedding holes 140 are detachably inserted with mounting feet 810, and the bottom wall of the embedding holes 140 is provided with a weighing sensor 900, and the mounting feet 810 are provided with a second mounting hole 811 in the up-down direction, and a top rod 820 is slidably mounted in the second mounting hole 811, and the top end of the top rod 820 abuts against the weighing sensor 900, and the bottom end of the top rod 820 is provided with a foot pad 821, and the foot pad 821 protrudes from the second mounting hole 811, wherein the weighing sensor 900 is electrically connected to the main control circuit board of the cat litter box. Therefore, by using the mounting feet 810, the top rod 820 and the foot pad 821 can slide up and down relative to the base 100, and when the cat litter box is correctly placed on the ground, the foot pad 821 contacts the ground to achieve an anti-slip effect, and at the same time, the top rod 820 is pressed against the weighing sensor 900, thereby making the cat litter box weighable. In addition, when the weight of the cat litter box exceeds a preset range, the lower end of the mounting foot 810 contacts the ground, so that the push rod 820 will not continue to push upward, thereby providing overload protection for the weighing sensor 900.

[0048] Reference Figure 8 and Fig. 9 In order to fix the mounting foot 810 and facilitate the disassembly and assembly of the mounting foot 810, a limit card slot 150 is set in the embedding hole 140, and a limit buckle 830 is movably installed in the mounting foot 810. The limit buckle 830 can be a hard component. A reset member 840 is set between the limit buckle 830 and the mounting foot 810. An operating part 831 is set on the limit buckle 830, and the operating part 831 is penetrated to the outside of the support member, wherein the reset member 840 can drive the limit buckle 830 to move and be locked in the corresponding limit card slot 150 to limit the mounting foot 810 from being separated from the corresponding insertion hole, and the operating part 831 is used to drive the limit buckle 830 to move out of the limit card slot 150. Therefore, when assembling the mounting foot 810, it is only necessary to align the limiting buckle 830 with the position of the limiting slot 150 and directly insert the mounting foot 810 into the embedding hole 140. When the mounting foot 810 needs to be disassembled, the limiting buckle 830 can be driven to move out of the limiting slot 150 through the operating part 831, and then the support member can be easily taken out. Compared with setting an elastic buckle on the mounting foot 810, the mounting foot 810 is more labor-saving and convenient to assemble and disassemble.

[0049] Reference Fig. 9 In a specific process, the limit buckle 830 can be rotatably installed in the mounting foot 810, or the limit buckle 830 can slide radially in the mounting foot 810, thereby, the pressing operation part 831 can drive the limit buckle 830 to move out of the limit slot 150.

[0050] In some embodiments, the pressure cover 210 is provided with a third mounting groove 214, and a limiting protrusion 215 is provided on the lower side wall of the third mounting groove 214. The upper end of the operating panel 220 can be movably inserted in the third mounting groove 214. The operating panel 220 is provided with a buckle 221. The buckle 221 and the limiting protrusion 215 cooperate with each other to limit the upper end of the operating panel 220 in the third mounting groove 214, so that the operating panel 220 can rotate relative to the pressure cover 210.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiment is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiment, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the present purpose.
