[0034] The present utility model provides a litter box that is convenient to clean.

[0035] In the embodiments of the present utility model, please refer to , the litter box that is convenient to clean includes:

[0036] A base 100, the base 100 is provided with an installation groove 120, a feces outlet 11 is opened on the bottom wall of the installation groove 120, and rolling members are provided on the wall of the installation groove 120;

[0037] A feces collection tray 300, the feces collection tray 300 is connected to the base 100 and communicated with the feces outlet 110; and

[0038] The roller 200 is rotatably installed in the installation groove 120. The outer surface of the roller 200 is conformally arranged with the groove wall of the installation groove 120 and is in rolling contact with the rolling member. The roller 200 is provided with an open bin 210 for accommodating cat litter.

[0039] In the technical solution of the present utility model, the feces collection tray 300 is arranged below the base 100 and is located below the feces outlet 110. Among them, the rolling member is independently exposed in the installation groove 120. The installation groove 120 is only provided with the feces outlet 110 and is communicated with the feces collection tray 300 through the feces outlet 110, so that the impurities in the installation groove 120 can only fall into the feces collection tray 300. Here, the roller 200 is rotatably arranged in the installation groove 120. Through the guidance of the rolling member, the rotation smoothness of the roller 200 is improved, so that the fecal mass in the roller 200 can enter the feces collection tray 300 from the open bin 210 through the feces outlet 110. During the process of cleaning the cat litter box, the impurities cleaned from the roller 200 can enter the feces collection tray 300 through the installation groove 120, and the impurities cleaned from the installation groove 120 also enter the feces collection tray 300 through the feces outlet 110. That is to say, all the impurities in the cat litter box are collected by the feces collection tray 300. Finally, the impurities in the feces collection tray 300 are poured out and the feces collection tray 300 is cleaned, then the cleaning of the cat litter tray can be completed. In this way, all the impurities in the cat litter tray can be cleaned into the feces collection tray 300, avoiding impurities such as broken cat litter and broken fecal masses from falling into the interior of the base 100 and being difficult to clean, thereby improving the convenience of cleaning the cat litter box.

[0040] It should be noted that a cavity is provided inside the base 100, so that on the basis of being able to support the roller 200 and the feces collection tray 300, the base 100 can maintain a good shape, thus ensuring the overall appearance of the cat litter box. Among them, the rolling member can guide the rotation of the roller 200. Even when impurities are stuck between the roller 200 and the installation groove 120, the rotation smoothness of the roller 200 can be ensured, improving the convenience of cleaning or discharging feces. At the same time, the rolling member is arranged in the installation groove 120 and can be specifically arranged adjacent to the feces outlet 110. The installation groove 120 does not have an avoidance opening due to the arrangement of the rolling member, so that the lower part of the rolling member is still the groove wall of the installation groove 120. In this way, it is avoided that impurities such as broken cat litter and broken fecal masses fall into the base 100 from the position of the rolling member and are difficult to clean. In addition, for the rotating shaft of the roller 200, the rotating connection between the rotating shaft of the roller 200 and the installation groove 120 is arranged adjacent to the groove opening of the installation groove 120, which can prevent impurities such as broken cat litter and broken fecal masses from invading the rotating connection between the rotating shaft of the roller 200 and the installation groove 120. At the same time, the shape of this connection is adapted to the end of the rotating shaft of the roller 200, avoiding a large gap and preventing impurities such as broken cat litter and broken fecal masses from remaining, thereby reducing the cleaning difficulty.

[0041] Further, in this embodiment, please refer to Figures 2 to 5, the rolling member is disposed at the periphery of the excrement outlet 110. Without loss of generality, the feces collection tray 300 is vertically opposite to the excrement outlet 110 and the rolling member, so that impurities falling from the rolling member or the excrement outlet 110 will fall into the feces collection tray 300. Thus, in this embodiment, an avoidance hole may be formed in the groove wall of the installation groove 120 corresponding to the rolling member to ensure the free rotation of the rolling member and facilitate the formation of the installation groove 120. Or, the groove wall of the installation groove 120 corresponding to the rolling member may not be provided with an avoidance hole, and the groove portion recessed to avoid the rolling member is arranged to penetrate along the groove wall of the installation groove 120 towards the excrement outlet 110. Therefore, on the premise of ensuring the stable rotation of the roller 200, impurities such as crushed cat litter and fecal masses can fall into the feces collection tray 300 more accurately. Of course, in other embodiments, the rolling member may also be disposed at a position far from the excrement outlet 110, and the installation groove 120 is recessed with an avoidance groove corresponding to the rolling member to avoid interfering with the rotation of the rolling member.

[0042] Further, in this embodiment, please continue to refer to Figures 3 to 6 , a movable groove 130 is further recessed in the bottom wall of the installation groove 120. The movable groove 130 penetrates towards the excrement outlet 110, and the rolling member is rotatably disposed in the movable groove 130. It can be understood that the movable groove 130 can avoid the rolling member and ensure the smooth rotation of the rolling member. Moreover, the movable groove 130 also provides a positioning reference for the installation of the rolling member, thereby improving the installation convenience of the rolling member. Thus, by making the movable groove 130 penetrate along the groove wall of the installation groove 120 towards the excrement outlet 110, the impurities falling into the movable groove 130 can be simply guided to the excrement outlet 110 to be collected by the feces collection tray 300, avoiding the impurities from falling into the base 100 or other difficult-to-clean positions of the cat litter box, thereby improving the cleaning convenience of the cat litter box. Of course, in other embodiments, the movable groove 130 may also be recessed from the installation groove 120 into a semicircle and does not penetrate the groove wall of the installation groove 120.

[0043] Specifically, in this embodiment, please refer to Figures 3 to 6 and Figure 3 , the rolling member is configured as a roller 140, and the rotation direction of the roller 140 is parallel to the rotation direction of the roller 200. Thus, under the action of the roller 140, the roller 200 can rotate back and forth around its rotation axis, and by using the supporting action of the roller 140, the stress on the rotating shaft of the roller 200 is reduced, and the use stability of the cat litter box is improved. In another embodiment, the rolling member may also be configured as a ball.

[0044] In one embodiment, please refer to Figure 6, the base 100 is respectively provided with rotating grooves 150 on the opposite side walls of the installation groove 120. The end portions of the rotating shafts of the rollers 200 are rotatably installed in the rotating grooves 150, and the rotating grooves 150 communicate with the installation groove 120. It can be understood that the rotating grooves 150 are recessed and formed from the side wall of the installation groove 120. The rotating shafts of the rollers 200 rotate in the corresponding rotating grooves 150, and the bottom walls of the two rotating grooves 150 are arranged opposite to each other. In this way, the rotating grooves 150 can provide support for the rotation of the rollers 200 and ensure the stability of the rotation of the rollers 200. At the same time, the openings of the rotating grooves 150 communicate with the installation groove 120, so that the impurities falling into the rotating grooves 150 can slide into the installation groove 120, thereby preventing the impurities from staying in the rotating grooves 150 and improving the cleanliness of the litter box and the convenience of cleaning the litter box. Of course, in other embodiments, two opposite rotating channels can also be opened on the opposite side walls of the installation groove 120, and the end portions of the rotating shafts of the rollers 200 can also pass through the corresponding rotating channels and remain stable axially relative to the rotating channels.

[0045] Further, in this embodiment, please refer to Figures 2 to 4 and Figure 3 , from the bottom wall of the rotating groove 150 to the installation groove 120, the connecting groove includes a driving section 151 and a bearing section 152 distributed in sequence. The diameter of the bearing section 152 is larger than that of the driving section 151, and the bearing of the rotating shaft of the roller 200 is installed in the bearing section 152. It can be understood that in the direction from the bottom of the rotating groove 150 to its opening, the rotating groove 150 expands outwards in a flared shape. In this way, the impurities in the rotating groove 150 can fall into the installation groove 120 more smoothly, thereby preventing the impurities from staying. At the same time, a bearing is installed in the bearing section 152 to form a certain degree of sealing protection for the rotating groove 150 at the opening where the rotating groove 150 communicates with the installation groove 120, preventing the impurities from falling into the rotating groove 150 from the opening of the rotating groove 150. Thus, while ensuring the stable rotation of the roller 200, it is also convenient to clean the litter box. Among them, a driving member (not shown in the figure) is provided in the base 100. In this embodiment, the driving member is configured as a motor. A driving opening is provided in the driving section 151, and the driving gear 160 provided on the driving member is exposed in the driving section 151 from the driving opening, and then the rotating shaft of the roller 200 is driven to rotate through the driving gear 160. The bearing provided in the bearing section 152 can prevent impurities from invading the driving section 151, and further prevent the impurities from falling into the base 100 from the driving opening of the driving section 151, thereby reducing the cleaning difficulty of the litter box.

[0046] Specifically, in one embodiment, please refer to and Figure 4, the litter box is also provided with an inner shovel 400. The inner shovel 400 rotates coaxially with the roller 200, and the opposite ends of the rotating shafts of the two are respectively engaged with the driving gears 160 in the two rotating grooves 150. That is, the base 100 is provided with driving members and driving gears 160 corresponding to the two rotating grooves 150. One driving gear 160 drives the rotation of the rotating shaft of the roller 200, and one driving gear 160 drives the rotation of the rotating shaft of the inner shovel 400. In this way, the inner shovel 400 is used to scrape the side wall inside the roller 200, avoiding the situation that the fecal mass adheres to the cavity wall of the roller 200 and is not cleaned or the cleaning is incomplete, thereby improving the automatic cleaning ability of the litter box. In addition, two independent driving gears 160 are provided. When the roller 200 needs to rotate, the roller 200 is driven to rotate by a driving member so that the cat litter and the fecal mass in the roller 200 are separated. During this process, the other driving member can drive the inner shovel 400 to rotate according to the needs, so as to improve the separation rate of the cat litter and the fecal mass while ensuring the cleaning effect of the inner wall of the roller 200. In this way, the two driving members can separate the fecal mass and clean the roller 200 according to the actual environmental needs, improving the practicability and use experience of the litter box.

[0047] In one embodiment, please refer to Figure 1 and Figure 2 , the base 100 further includes a waterproof ear 170. The rotating groove 150 penetrates through the notch of the installation groove 120. At the notch of the installation groove 120, the waterproof ear 170 covers the rotating groove 150. It can be understood that the rotating groove 150 penetrates upward through the notch of the installation groove 120. In this way, when disassembling and assembling the roller 200, the roller 200 can be installed from the notch of the installation groove 120 into the rotating groove 150, thereby improving the convenience of disassembling and assembling the roller 200. Here, the waterproof ear 170 is provided to block the rotating groove 150 and prevent external impurities from invading the rotating groove 150 and affecting the rotation of the roller 200. Specifically, when cleaning the litter box, or when the litter box is in an outdoor environment, the waterproof ear 170 can prevent external water from seeping into the rotating groove 150, thereby avoiding damage to components such as the rotating shaft and driving gear 160 of the roller 200, and thus ensuring the stability of the rotation of the roller 200 and the use stability of the litter box. Of course, in other embodiments, the rotating groove 150 may not penetrate through the notch of the installation groove 120 so that the rotating shaft of the roller 200 is not exposed outside the installation groove 120.

[0048] Further, in this embodiment, please continue to refer to Figure 3 and Figure 4, a guiding and limiting rib 153 is provided adjacent to the rotating groove 150 on the base 100. The guiding and limiting rib 153 extends parallel to the rotating shaft of the roller 200. A guiding clamping groove 171 is provided on the waterproof ear 170, and the guiding and limiting rib 153 is clamped in the guiding clamping groove 171. It should be noted that the waterproof ear 170 is disassembled and assembled along the direction parallel to the rotating shaft of the roller 200. During the installation process of the waterproof ear 170, the guiding and limiting rib 153 and the guiding clamping groove 171 are adaptively clamped, and the waterproof ear 170 is restricted from disengaging from the base 100 in the notch direction of the installation groove 120. While improving the disassembly and assembly convenience of the waterproof ear 170, the installation stability of the waterproof ear 170 on the base 100 is also ensured. Of course, in other embodiments, the guiding and limiting rib 153 can also extend along the notch direction of the installation groove 120, that is, the guiding and limiting rib 153 and the guiding clamping groove 171 extend in the vertical direction.

[0049] In one embodiment, please refer to Figure 3 and Figure 4 , a sealing ring 180 is provided around the periphery of the outlet 110 of the installation groove 120. The roller 200 has a use state for pets to defecate and a cleaning state for cleaning fecal masses. In the use state, the outer periphery of the roller 200 is hermetically abutted against the sealing ring 180. It should be noted that in the use state, the opening of the opening bin 210 is arranged in the same direction as the notch of the installation groove 120, so as to facilitate pets to enter and exit the opening bin 210 for defecation. In the use state, the outer surface of the roller 200 tightly presses against the sealing ring 180 to achieve the purpose of sealing the outlet 110, thereby preventing the smell of the fecal mass in the feces collection tray 300 from overflowing into the environment and improving the user experience.

[0050] Among them, it is possible that a boss or a convex ring (not shown in the figure) can be provided at the lower part of the drum 200. In the use state, the boss or the convex ring abuts against the sealing ring 180 to achieve the sealing of the feces outlet 110. For the rolling member, an avoidance opening can be provided on the boss or the convex ring to ensure the stability and smoothness of the rotation of the drum 200. When the drum 200 is in the feces cleaning state, the sealing relationship between the drum 200 and the sealing ring 180 is released, so that the opening of the opening bin 210 can communicate with the feces outlet 110, thereby discharging the feces mass into the feces collection basin. It can be understood that for the switching of the sealing relationship between the sealing ring 180 and the drum 200, after the drum 200 disengages from the sealing relationship with the sealing ring 180 in one direction, it can rotate back and forth on this side. For example, one side of the sealing ring 180 has a larger thickness and the other side has a smaller thickness. Correspondingly, one side of the boss or the convex ring has a smaller protruding thickness and the other side has a larger protruding thickness. The drum 200 rotates towards the side with the smaller thickness of the sealing ring 180 to switch to the feces cleaning state. Then the inner shovel 400 cleans the drum 200 and separates the feces mass from the cat litter until it rotates to pour the feces mass in the opening bin 210 into the feces collection basin, and finally rotates back to the use state. During this process, impurities such as cat litter or feces mass clamped between the drum 200 and the wall of the installation groove 120 will also fall into the feces collection tray 300. It is also possible that one of the corresponding parts of the sealing ring 180 and the drum 200 has the ability of relative lifting (not shown in the figure). In the use state, the sealing ring 180 and the drum 200 move towards each other until they are in close contact. In the feces cleaning state, the sealing ring 180 and the drum 200 move away from each other until they are separated. Specifically, the sealing ring 180 can be driven to lift by a motor, and the groove wall of the installation groove 120 that accommodates the sealing ring 180 is recessed and at least partially penetrates to the feces outlet 110 to prevent impurities from being stuck in the sealing ring. It is also possible that the sealing ring 180 is configured with a certain elastic deformation ability, which can not only avoid interfering with the rotation of the drum 200, but also ensure the convenience of the drum 200 to switch between the use state and the feces cleaning state. Of course, in other embodiments, a baffle can also be provided at the feces outlet 110. In the use state, the baffle covers the feces outlet 110. In the feces cleaning state, the baffle opens the feces outlet 110. An independent driving mechanism can be provided for the baffle to be synchronized with the drum 200 in the use state and the feces cleaning state. Or, a transmission member can be provided to synchronously drive the movement of the baffle by the driving member that drives the rotation of the drum 200. Or, the sealing ring 180 is provided at the outer bottom of the drum 200. Referring to the above description, it has a thickness difference, lifting and telescoping or elastic deformation ability in the upstream and downstream directions of rotation to ensure the convenience of the drum 200 to switch between the use state and the feces cleaning state. Or, the rolling member is configured as the sealing ring 180, that is, the rolling member is arranged in a ring around the periphery of the feces outlet 110 and can rotate self-reliantly. Correspondingly, referring to the above description, it also has a thickness difference, lifting and telescoping or elastic deformation ability in the upstream and downstream directions of rotation to ensure the convenience of the drum 200 to switch between the use state and the feces cleaning state.

[0051] In one embodiment, a ladder (not shown in the figures) is provided on the base 100, and the ladder extends obliquely downward from the opening of the opening bin 210. It can be understood that the upper end of the ladder is adjacent to the opening of the opening bin 210, and the lower end of the ladder is adjacent to the base surface where the litter box is placed. In the use state, the pet can enter and exit the opening bin 210 through the ladder for defecation, so as to reduce the difficulty for the pet to use the litter box, thereby improving the user experience. Specifically, the ladder can be an independent component or formed on the surface of the base 100.

[0052] Furthermore, in this embodiment, the base 100 is provided with a receiving bin (not shown in the figures) communicating with the feces collection tray 300, and the receiving bin is used to receive the ladder. The ladder includes multiple steps and a support plate conforming to the outer side wall of the base 100. The steps are arranged on the support plate, and the support plate is pivotally connected to the lower edge of the receiving bin. It can be understood that in the use state, the pet enters and exits the opening bin 210 through the steps on the ladder. When the ladder is not in use or when the ladder is being cleaned, the ladder can be flipped into the receiving bin so that the support plate is coplanar with the outer side wall of the base 100, thereby ensuring the integrity of the appearance of the litter box. At the same time, after the ladder is received in the receiving bin, impurities such as broken cat litter on the steps also fall into the receiving bin and then enter the feces collection tray from the receiving bin, so as to avoid the scattering of impurities such as broken cat litter near the litter box and realize the automatic cleaning of the ladder, improving the user experience. Of course, in other embodiments, the ladder can also be fixed outside the base 100, or the ladder is connected to the base 100 in a pull-out manner.

[0053] In one embodiment, please refer to Figure 2 and Figure 5 , the feces collection tray 300 is detachably installed at the lower part of the base 100. The base 100 is provided with a plurality of support legs 190, and the plurality of support legs 190 are distributed along the circumference of the feces collection tray 300 and are staggered from the disassembly and assembly direction of the feces collection tray 300. The plurality of support legs 190 form a supporting effect on the base 100 in the circumferential direction to ensure the stability of the litter box. At the same time, a space for disassembly and assembly of the feces collection tray 300 can be formed between the support legs 190, so that the feces collection tray 300 can be disassembled and assembled between the plurality of support legs 190, thereby facilitating the user's use. Specifically, the length of the support legs 190 is adjustable to adapt to the placement position of the litter box and leveling. Of course, in other embodiments, the lower surface of the base 100 is a plane and directly supports the placement position of the litter box. There is an installation space between the feces outlet 110 below the roller 200 and the lower surface of the base 100, and the feces collection tray 300 is detachably installed in this installation space and is vertically opposite to the feces outlet 110.

[0054] In one embodiment, please refer to Figure 1 and Figure 2 Figure 1 Figure 2, at the edge of the open bin 210, the drum 200 is provided with a sand baffle 220, and the sand baffle 220 extends along both ends of the rotating shaft of the drum 200. Without loss of generality, the sand baffle 220 is arranged on one edge of the open bin 210 close to the ladder and is opposite to the edge where the open bin 210 discharges the fecal mass into the fecal collection tray 300. Thus, when the drum 200 is in use, if a pet has a sand-scratching action when entering the litter box to defecate, it will cause some cat litter to be scratched out of the open bin 210 by the pet. At this time, the sand baffle 220 can block the cat litter, which not only avoids the waste of cat litter being scratched out of the litter box, but also avoids the cat litter falling between the drum 200 and the installation groove 120 to form a resistance to the rotation of the drum 200, thereby reducing the use cost of the litter box and improving the user experience.

[0055] The above are only optional embodiments of the present invention, and do not limit the protection scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields is included in the protection scope of the present invention.
