[0035] The utility model provides a cat litter basin convenient to remove.

[0036] Please refer to Figure 1 And Figure 3 In an embodiment of the present application, the cat litter basin convenient to remove comprises:

[0037] The basin body 100 is provided with a containing cavity 110, which is provided in an open manner and used for containing cat litter.

[0038] The rolling member 200 is arranged at the bottom of the basin body 100 and used for supporting the basin body 100.

[0039] The handle member 300 is arranged on the basin body 100 and avoids the opening of the containing cavity 110, and the handle member 300 is used for being held by a user.

[0040] The technical scheme of the present application provides the rolling member 200 at the bottom of the basin body 100, the cat litter basin can be supported on the ground or other placement surface through the rolling member 200, in the process that the user acts on the handle member 300 to drive the cat litter basin to move, the rolling member 200 slides on the ground, thereby reducing the friction between the cat litter basin and the ground, so that the user can easily move the cat litter basin to a predetermined position, and the handle member 300 avoids the opening of the containing cavity 110, avoids the interference of the cat litter basin on the pet, and also provides a comfortable holding point for the user, so that the carrying process is more comfortable and controllable. In this way, the user can easily move the cat litter basin to a predetermined position according to the need, and the use experience of the user is improved.

[0041] It should be noted that the handle 300 can be arranged at any position of the basin body 100 avoiding the opening of the accommodating cavity 110, and the position for the user to hold conveniently and the environment for the user to place should be the main consideration, such as vertical extension arrangement, horizontal extension arrangement, or inclined arrangement, etc. The handle 300 can be fixedly arranged on the basin body 100, or movably arranged on the basin body 100 to adapt to different users and placement environments. Similarly, for the rolling member 200, the rolling member 200 can be detachably arranged on the bottom of the basin body 100, or fixedly arranged, or partially arranged on the bottom of the basin body 100 and partially arranged on the supporting part 140. During normal use of the litter box, the basin body 100 is supported on the ground by the supporting part 140 to keep the litter box stable and ensure normal use of the pet. When the litter box needs to be moved, the posture of the litter box is changed so that the basin body is supported on the ground only by the rolling member 200, and then the litter box is moved more conveniently by pulling the handle.

[0042] In an embodiment, referring to Figure 3 and Figure 4 , the handle 300 is arranged on the vertical side wall of the basin body 100, and the rolling member 200 is arranged adjacent to the handle 300. It can be understood that the handle 300 is located on the vertical side wall, so that the user can naturally stretch out his hand to hold it when carrying the litter box, without needing to bend over or twist his body, thereby reducing the physical burden during carrying. At the same time, the rolling member 200 is arranged adjacent to the handle 300, so that the user only needs to slightly change the posture of the basin body 100 while holding the handle 300, so that the basin body 100 is supported on the ground only by the rolling member 200, so that the user can easily push the litter box to move, thereby improving the efficiency and stability of carrying. In addition, the position of the handle 300 on the vertical side wall can also be adjusted to adapt to users of different heights and body shapes, so that they can carry the litter box in a comfortable way. Of course, in other embodiments, the arrangement position of the handle 300 can also be adjusted according to the in-out direction of the basin body 100 during use, to avoid hindering the normal use of the litter box, or the handle 300 can be detachably arranged on the bottom of the basin body 100, and then connected to the basin body 100 when needed.

[0043] Specifically, in the present embodiment, referring to Figures 1 to 3The handle 300 is located on the side wall of the litter box body 100 opposite to the opening of the receiving cavity 110. This ensures that the handle 300 does not interfere with direct contact between the pet / user and the litter when using the litter box. The pet can normally enter the litter box to defecate, and the user can add or clean litter without being blocked or affected by the handle 300. It also provides a positioning reference for the handle 300, making it easy for the user to quickly grasp it. Furthermore, when moving the litter box, the handle 300 is tilted downwards, ensuring that the opening of the receiving cavity 110 always faces upwards, thus preventing litter from scattering and reducing the possibility of spillage. This helps maintain the cleanliness and hygiene of the litter box, reducing cleaning and maintenance workload. Of course, in other embodiments, the handle 300 may also be placed on the side wall of the basin body 100 adjacent to the opening of the receiving cavity 110.

[0044] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 6 The handle 300 is retractably mounted on the vertical side wall of the litter box body 100, having both a retracted and an extended state. The extension and retraction directions of the handle 300 are parallel to the vertical direction. It can be understood that the retractable design of the handle 300 significantly reduces its volume when in the retracted state, thus not occupying additional space and lowering the space requirements for placing the litter box. This is especially important for users with limited living space, ensuring that the litter box does not become an obstacle when not in use. Simultaneously, the retracted handle 300 reduces the possibility of collisions with other items or people in the home, avoiding unnecessary injury or damage, and does not interfere with the pet's normal use of the litter box. Furthermore, when the litter box needs to be moved, the user can extend the handle 300 to an appropriate length, providing a comfortable grip point suitable for the user's height and strength, which helps maintain stability during transport and reduces physical strain. Of course, in other embodiments, the handle 300 can also be fixedly mounted on the litter box body 100, and only in one state.

[0045] Furthermore, in this embodiment, please refer to Figure 3 , Figure 4 and Figure 6, the vertical side wall of the basin body 100 is provided with a receiving cavity, and the handle piece 300 is arranged in the receiving cavity. In the retracted state, the handle piece 300 is accommodated in the receiving cavity. It can be understood that when the handle piece 300 is in the retracted state and completely accommodated in the receiving cavity, the appearance of the cat litter basin is more neat and beautiful, and the overall visual effect of the home environment is improved, making it more harmonious and unified. At the same time, the hidden handle piece 300 design reduces the possibility of accidental touch or tripping of users in daily life, especially in narrow spaces or busy environments, this design can avoid unnecessary interference and safety hazards. In addition, the receiving cavity provides a safe storage space for the handle piece 300, avoiding damage from the external environment such as collision, scratching or pollution during use, which helps to prolong the service life of the handle piece 300 and maintain its good use state. Of course, in other embodiments, the handle piece 300 can also be exposed outside the basin body 100.

[0046] Further, in the present embodiment, please refer to Figures 1 to 3 , the handle piece 300 includes a grip portion 320 and a telescopic portion 310 connected together, in the retracted state, the telescopic portion 310 is accommodated in the receiving cavity, and the grip portion 320 is adaptively located at the cavity opening of the receiving cavity and is conformally arranged with the outer side wall of the basin body 100. It can be understood that the conformal arrangement of the grip portion 320 with the outer side wall of the basin body 100 makes the handle piece 300 visually integrated with the basin body 100, reducing the sense of strangeness, not only improving the overall beauty of the cat litter basin, but also making it more in line with the aesthetic standards of modern homes. At the same time, the close fit of the grip portion 320 with the outer side wall of the basin body 100 reduces the occupation of the surrounding space by the handle piece 300 in the retracted state, making the cat litter basin more space-saving during storage and use, especially suitable for limited space in the home environment. In addition, the conformally arranged grip portion 320 and the outer side wall of the basin body 100 form a good support structure, reducing the possibility of deformation or damage of the handle piece 300 due to external forces, which helps to enhance the overall stability and durability of the cat litter basin. Of course, in other embodiments, the grip portion 320 can also protrude and be exposed outside the outer side wall of the basin body 100 to facilitate quick grabbing by users.

[0047] Specifically, in the present embodiment, the holding portion is movably connected to the telescopic portion, and in the retracted state, the holding portion has a first position adapted to the cavity opening of the accommodation cavity and a second position protruding out of the cavity opening of the accommodation cavity. (not shown) It can be understood that the holding portion can be flexibly switched between the first position and the second position as needed, both maintaining the hidden simplicity and beauty, and facilitating users to quickly find and use when needed, thereby providing double functions, both meeting the aesthetic needs and ensuring the practicability. Among them, when the holding portion is in the first position, it is completely integrated into the cavity opening of the accommodation cavity, reducing visual interference and making the litter box look more clean and integrated; when the litter box needs to be carried or moved, the user only needs to simply switch the holding portion to the second position, so that it can be easily held and operated, improving the convenience and comfort of use. In addition, the hidden holding portion design reduces the risk of accidental collision or tripping, especially in families with children, which can provide additional safety protection and reduce potential safety hazards. Of course, in other embodiments, the holding portion can also be fixedly adapted to the cavity opening of the accommodation cavity, and a pull ring or pull rope can be provided on the exposed side to pull the handle into the extended state.

[0048] In an embodiment, please refer to Figure 3 and Figure 6 The outer side wall of the basin body 100 is provided with a protruding portion 130, the protruding portion 130 has a first surface 131 inclined downward and relative to the outer side wall of the basin body 100, and the cavity opening of the accommodation cavity is opened on the first surface 131. It should be noted that the first surface 131 is inclined along the outer side wall of the basin body 100, and is inclined downward from top to bottom and gradually increases the spacing between the outer side walls of the basin body 100, so that the opening of the accommodation cavity is properly inclined upward. It can be understood that the inclined first surface 131 can naturally guide the position of the user's hand, when the user needs to hold the holding portion 320 of the handle 300, their hands will instinctively slide along the inclined surface to the cavity opening position, making holding more smooth and intuitive. At the same time, the design of the protruding portion 130 provides a separate space for the holding portion 320, so that the user will not conflict with other parts of the basin body 100 when grabbing the holding portion 320, thereby providing the user with a larger holding area and a more comfortable holding experience. In addition, the protruding portion 130 and its inclined first surface 131 are more prominent in vision, so that the user can more easily identify the position of the holding portion 320. Of course, in other embodiments, the cavity opening of the accommodation cavity can also be formed with the outer peripheral wall of the basin body 100.

[0049] In an embodiment, please refer to Figures 3 to 5It is to be noted that the universal wheel can rotate freely by 360 degrees on the horizontal plane, so that the litter box can change direction only by the rotation of the wheel without changing the overall direction of the device, thereby improving the flexibility of the mobile device and enabling it to easily cope with various complex movement requirements. For the user who needs to change the moving direction of the litter box, he or she only needs to push or pull gently to easily move and adjust the position of the device without having to move or adjust the overall direction of the device, thereby greatly reducing the labor intensity of the user. Of course, in other embodiments, the rolling member 200 can also be provided as a one-way pulley or a common roller.

[0050] In an embodiment, the rolling member is provided with a locking structure (not shown in the figure) for locking and unlocking the active state of the rolling member. It can be understood that the locking structure can lock or unlock the active state of the rolling member, thereby achieving control over the movement of the litter box. When the litter box needs to be moved, the rolling member can be unlocked to enable it to roll freely, and the litter box can be easily carried and moved to facilitate the user to clean the litter box or change the position of the litter box. When it is not necessary to move, the rolling member is locked to prevent it from moving accidentally and to ensure the stability of the litter box in the normal use state. In the unlocked state, although the rolling member allows the litter box to move, the design of the locking structure can generally ensure the stability during movement. For example, through a reasonable locking mechanism, the rolling member can be prevented from slipping or deviating during movement, thereby ensuring that the litter box moves smoothly and safely. Of course, in other embodiments, the locking structure can not be provided on the rolling member, but a locking anti-skid structure can be provided on the pot body. When the litter box does not need to be moved, the anti-skid structure is abutted to the ground, so that the litter box can be kept stable.

[0051] In an embodiment, please refer to Figures 3 to 5 The bottom of the pot body 100 is concavely provided with a clearance groove 120, and the rolling member 200 is installed in the clearance groove 120 and partially protrudes downward from the slot opening of the clearance groove 120 to the bottom of the pot body 100. The design of the clearance groove 120 enables the rolling member 200 to be partially embedded inside the pot body 100 instead of being completely suspended below the bottom of the pot body 100. This can effectively reduce the overall height of the litter box, making it more compact and low. This is particularly important for users who need to save floor space or adapt to low furniture. At the same time, it also ensures that the litter box can be easily moved and prevents it from tipping over or sliding sideways during movement. In addition, the clearance groove 120 also prevents the rolling member 200 from directly contacting sharp objects or dirt on the ground, thereby providing a certain degree of protection for the rolling member 200 and prolonging the service life of the rolling member 200. Of course, in other embodiments, the rolling member 200 can also be directly provided on the flat bottom of the pot body 100.

[0052] Further, in the present embodiment, please refer to Figures 3 to 5 The clearance groove 120 is arranged at the corner position of the bottom of the litter box body 100. When the litter box is moved, the clearance groove 120 at the corner position and the rolling member 200 therein can provide better support, helping to reduce the shaking of the litter box during movement, so that it can be moved more smoothly from one position to another. At the same time, the rolling member 200 at the corner position can roll along the predetermined path to guide the moving direction of the litter box, reducing the possibility of deviating from the predetermined direction. In addition, the rolling member 200 at the corner position enables the user to more easily control the direction and speed of the litter box when moving it, providing better maneuverability, so that the user can easily adjust the position of the litter box as needed. Similarly, for the support stability of the litter box in use, the rolling member 200 can increase the contact area with the ground. This helps to distribute the weight of the litter box and reduce the single-point pressure, thereby improving the stability of placement, such as preventing the litter box from tipping over when subjected to lateral force. In addition, it also enables the litter box to remain stable even when there is a slight unevenness or inclination on the ground. Of course, in other embodiments, the clearance groove 120 or the rolling member 200 can also be arranged at the center of the bottom of the litter box body 100.

[0053] In an embodiment, please refer to Figures 2 to 5 The bottom of the litter box body 100 is also provided with a support portion 140, and the support portion 140 and the rolling member 200 are respectively arranged adjacent to the opposite side edges of the bottom of the litter box body 100. It can be understood that the support portion 140 is located at a side edge of the bottom of the litter box body 100, which can provide stable support when the litter box is placed on the ground, helping to prevent the litter box from tilting or overturning during use due to uneven force. At the same time, the weight of the litter box can be distributed to a larger contact area, which helps to reduce the single-point pressure and prevent the ground from deforming or being damaged due to long-term pressure. In cooperation with the rolling member 200, the combined design of the support portion 140 and the rolling member 200 enables the litter box to maintain stability while also having mobility. The rolling member 200 is located at the other side edge, which facilitates the user to move the litter box as needed; while the support portion 140 ensures that the litter box remains stable in the stationary state, which can effectively prevent the cat from being injured when using the litter box due to the shaking or overturning of the litter box. Of course, in other embodiments, a limiting structure can also be arranged on the rolling member 200, which limits the rolling of the rolling member 200 when the litter box does not need to be moved, so as to ensure the stability of the litter box.

[0054] The above merely illustrates the exemplary embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields under the technical concept of the present application and by using the content of the present application specification and drawings are included in the patent protection scope of the present application.
