Description

Technical Field

[0001] This utility model relates to the field of intelligent cat litter boxes, specifically to a semi-open cat litter box ball chamber body structure. Background Technology

[0002] Existing smart litter boxes mainly have two types of ball chamber structures: one is composed of two hemispherical chambers joined together, and the other is a semi-open ball chamber structure. Both of these structures present some problems when cleaning up cat waste.

[0003] First, the two hemispherical compartments assembled together form a closed system, with an entrance only in one hemisphere, and the two hemispheres are connected by screws. This closed system makes it difficult for owners to directly observe their cats' littering behavior to assess their health. Furthermore, the assembled compartments have some hard-to-clean corners and areas that can easily trap litter and urine. The joint between the two compartments is also prone to leakage.

[0004] In addition, while the semi-open ball pit allows owners to easily observe their cats' toilet habits, the curvature design of this type of ball pit is not ideal. This means that when cleaning, the cat feces removed by the filter cannot flow back into the collection tank at the bottom. Even with a deflector already installed, an additional deflector is needed to help guide the cat feces into the collection tank, increasing the production cost of the litter box.

[0005] Furthermore, both types of litter boxes have spherical bottom sand storage areas, resulting in low utilization rates. Also, due to the shape limitations, the sand surface is higher in the middle and lower on the sides after being laid out, making it very easy for the sand to stick to the bottom if the cat urinates from the side, as the side is further forward. Utility Model Content

[0006] To address the aforementioned technical problems of litter box ball compartments, such as difficult-to-clean dead corners, increased production costs due to the addition of additional guide plates, low utilization rate of the litter storage area, and easy adhesion of excrement to the bottom, this utility model provides a semi-open litter box ball compartment body structure.

[0007] This utility model provides a semi-open litter box ball chamber body structure, which includes: a ball chamber body, the ball chamber body structure being connected to a motor of the litter box base and rotating under the drive of the motor, a guide plate being disposed on the upper inner side of the ball chamber body, a filter plate being connected to the inner side of the guide plate, and a litter pad being disposed inside the ball chamber body. The inner sides of the ball chamber body are provided with guide surfaces, which are curved surfaces, and the bottom surface of the litter storage area at the bottom of the ball chamber body is a flat surface.

[0008] The semi-open litter box ball chamber structure provided by this utility model may also have the following feature: the transverse tangential angle between the guide surface and the horizontal line is greater than 25°.

[0009] The semi-open litter box ball chamber structure provided by this utility model may also have the following feature: when 4 liters of cat litter are laid flat in the litter storage area, the thickness of the cat litter at the center of the litter storage area is greater than 5 cm.

[0010] The semi-open litter box ball chamber body structure provided by this utility model may also have the following feature: the ball chamber body is a one-piece molded ball chamber body.

[0011] The semi-open litter box ball chamber body structure provided by this utility model may also have the following feature: the guide plate is detachably connected to the ball chamber body through a rotating assembly.

[0012] The semi-open litter box ball chamber body structure provided by this utility model may also have the following features: a buckle position is provided on the inner side of the guide plate, and a buckle is provided on one side of the filter plate, and the buckle is engaged with the buckle position.

[0013] The semi-open litter box ball chamber body structure provided by this utility model may also have the following features: a limiting groove is provided on the inner side of the ball chamber body along its circumference, and a limiting buckle is provided on the outer ring of the litter pad, with the limiting buckle engaging with the limiting groove.

[0014] The semi-open litter box ball chamber structure provided by this utility model may also have the following feature: the litter pad is located above the litter storage area.

[0015] The beneficial effects of this utility model are as follows:

[0016] The semi-open litter box ball compartment structure of this utility model includes a ball compartment body, a guide plate, a filter plate, and a litter pad. The ball compartment body is connected above the litter box's waste collection compartment and is connected to a motor on the base on both sides, allowing it to rotate under the motor's drive. The guide plate, filter plate, and litter pad are disposed within the ball compartment body. Specifically, the guide plate is located at the top inside the ball compartment body, the filter plate is connected to the inner side of the guide plate, and the litter pad surrounds the middle of the ball compartment body. Additionally, the two inner sides of the ball compartment body are provided with curved guide surfaces. The bottom surface of the litter storage area is flat.

[0017] Based on the semi-open litter box ball compartment structure, the one-piece molding of the ball compartment body avoids assembly gaps, thus preventing the formation of litter and urine traps in hard-to-reach areas and urine leakage from assembly gaps. Furthermore, the curved guide surface has a lateral tangential angle greater than 25° with the horizontal line. This angle allows litter in this area to naturally slide into the litter storage area at the bottom of the ball compartment and smoothly enter the waste collection opening, eliminating the need for additional guide plates and reducing production costs.

[0018] Furthermore, the bottom of the litter storage area is flat. When 4 liters of cat litter are laid evenly in this area, the litter thickness at the center is greater than 5 cm. Utilizing the flatness of the bottom surface, the same amount of litter can be laid thicker and higher compared to a spherical litter storage area, significantly reducing the problem of litter sticking to the bottom due to side urination. Simultaneously, because the litter thickness in the center is greater than 5 cm, it also prevents the center from sticking to the bottom. Attached Figure Description

[0024] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The semi-open litter box ball chamber structure in this embodiment is applied in a smart litter box, providing a ball chamber structure that is easy to clean and can empty clean litter.

[0026] like Figures 1-5 As shown, the semi-open litter box ball compartment structure 100 includes a ball compartment body 10, a guide plate 20, a filter plate 30, and a litter pad 40. Figure 1As shown, the semi-open litter box ball chamber body structure 100 is rotatably connected to the base of the smart litter box 200. A waste collection chamber is provided below the base, and a motor is provided at the connection point with the semi-open litter box ball chamber body structure 100, which can drive the semi-open litter box ball chamber body structure 100 to rotate.

[0027] The ball chamber body 10 is a one-piece ball chamber structure, with connecting gears 11 on the outer ends of both sides. These connecting gears 11 are connected to the motor on the base and can rotate under the drive of the motor.

[0028] Several limiting grooves 12 are provided along the circumference of the inner side of the sphere body 10, located in the lower middle part.

[0029] The inner sides of the ball-shaped hopper body 10 are provided with guide surfaces 13. The area formed on the inner side of the ball-shaped hopper body 10 by the construction lines (the outline of the ball-shaped hopper is a curved surface shape generated by rotating the construction lines along the axis of rotation, where the axis of rotation is the pivot formed between the two connecting gears 11) is the guide surface 13. This guide surface 13 is located outside the projection plane of the waste collection compartment opening, and its lateral tangential angle with the horizontal X-axis is greater than 25°. This angle range allows the cat litter on the guide surface 13 to be smoothly guided into the waste collection compartment.

[0030] Additionally, the bottom of the spherical container body 10 is a sand storage area 14, which is located below the limiting groove 12. The bottom surface of the sand storage area 14 is flat. Figure 5 As shown, when 4L of cat litter is laid flat in the litter storage area 14, the height h between its bottom surface and the top surface of the laid cat litter is greater than 5cm.

[0031] Rotating components are respectively provided on both sides of the front end of the deflector 20, and corresponding connecting holes 15 are provided on the ball tank body 10. The rotating components include a connecting groove and a rotary button. The connecting groove is provided on the deflector 20, corresponding to the position of the connecting hole 15. The rotary button extends into the connecting groove and the connecting hole, and its bottom is provided with a rotating protrusion, which can engage with the connecting hole 15 during rotation. When the rotating protrusion engages with the connecting hole 15, the deflector 20 is connected to the top of the inner side of the ball tank body 10.

[0032] The rear end of the baffle 20 has several snap-fit ​​positions, and one end of the filter plate 30 has several snap-fit ​​positions. The filter plate 30 is connected to the baffle 20 by snapping into the snap-fit ​​positions.

[0033] The litter pad 40 is a hollow circular structure. A limiting buckle is provided on the outer ring of the circle. The limiting buckle is inserted into the limiting groove 12 on the ball chamber body 10, so that the litter pad 40 is connected to the ball chamber body 10 and is located above the litter storage area 14.

[0034] The semi-open litter box ball compartment structure according to the above embodiment includes a ball compartment body, a guide plate, a filter plate, and a litter pad. The ball compartment body is connected above the litter box's waste collection compartment and is connected to a motor on the base on both sides, allowing it to rotate under the motor's drive. The guide plate, filter plate, and litter pad are disposed within the ball compartment body. Specifically, the guide plate is located at the top inside the ball compartment body, the filter plate is connected to the inner side of the guide plate, and the litter pad surrounds the middle of the ball compartment body. Furthermore, the two inner sides of the ball compartment body are provided with curved guide surfaces. The bottom surface of the litter storage area is flat.

[0035] Based on the semi-open litter box ball compartment structure, the one-piece molding of the ball compartment body avoids assembly gaps, thus preventing the formation of litter and urine traps in hard-to-reach areas and urine leakage from assembly gaps. Furthermore, the curved guide surface has a lateral tangential angle greater than 25° with the horizontal line. This angle allows litter in this area to naturally slide into the litter storage area at the bottom of the ball compartment and smoothly enter the waste collection opening, eliminating the need for additional guide plates and reducing production costs.

[0036] Furthermore, the bottom of the litter storage area is flat. When 4 liters of cat litter are laid evenly in this area, the litter thickness at the center is greater than 5 cm. Utilizing the flatness of the bottom surface, the same amount of litter can be laid thicker and higher compared to a spherical litter storage area, significantly reducing the problem of litter sticking to the bottom due to side urination. Simultaneously, because the litter thickness in the center is greater than 5 cm, it also prevents the center from sticking to the bottom.

[0037] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
