[0022] Referring to Figures 1 to 10, the present invention relates to a waterproof and stain-resistant paper cat litter box. A paper box 2 that is water and dirt resistant and a paper box body 1 made by joining together multiple sheets of assembled paperboard 11 The paper box body 1 is provided with a storage groove, and the surface of the paper box 2 is waterproof and dirt-resistant. The surface is provided with a waterproof and stain-resistant film, and the cat litter box is designed to be stable during transport and to prevent the accumulation of cat litter. The waterproof and dirt-resistant paper box can be switched between the collection state and the transportation state. 2 is folded into a flat structure (see FIG. 10), and the paper boxes 1 are stacked on top of each other. In the state where the cat litter is collected, the paper board 11 is divided into a plurality of assembled paper boards 11 (see FIG. 7). The waterproof and dirt-proof paper box 2 is unfolded and installed in the storage groove (see FIG. 6). The surface of the waterproof and stain-resistant paper box 2 is covered with a waterproof and stain-resistant film, and the storage groove Stay away from the interior walls.

[0023] The beneficial effects of this specific embodiment are as follows: Waterproof and stain-resistant during transportation. The anti-stick paper box 2 can be folded into a flat state, and the paper box bodies 1 can be stacked on top of each other. The cat litter box is divided into multiple stacked assembled paperboards 11. This design allows the cat litter box to be easily transported. It significantly reduces the space required for transportation and storage, facilitating lot transportation and warehousing, and reducing logistics costs. When it needs to be converted from the transport state to the cat litter collection state, the user Simply assemble the standing cardboard 11, unfold the waterproof and dirt-proof paper box 2, and place it in the storage groove. The whole process is quick and convenient, with no complicated installation steps required, The surface of the waterproof and dirt-resistant paper box 2 is waterproof and dirt-resistant. The anti-slip film effectively prevents cat feces from adhering, reducing cleaning difficulties and troubles. This design not only improves the user experience but also reduces the risk of sanitation caused by unclean cleaning. The paper cat litter box is more durable than the traditional plastic litter box. Environmentally friendly. Paper materials are easily decomposed and do not cause long-term pollution to the environment. As technology advances, paper cat litter boxes have become more sustainable. Therefore, the fabric of these cat litter boxes is relatively soft and does not catch the cat's claws like hard plastic. At the same time, the waterproof and stain-resistant design prevents cats from coming into contact with dirty substances while using it. The semi-closed design prevents contact and improves comfort for cats. It provides a private and enclosed space where your cat can feel more secure and hidden when defecating. This design is based on the cat's natural instinct to find hiding places and relieve themselves in their natural environment. Simulates natural behavior, helping to reduce anxiety and stress in cats and increasing their sense of security. In a semi-enclosed space, cats can feel at home without being disturbed by outside noise, people, or other pets. This is because they can focus more on their excretory activities. Helps your cat stay relaxed and comfortable, encouraging them to use the litter box The semi-closed design allows for more control over the diffusion within the odor chamber. By reducing the circulation of odors and dissipating them directly into the air, semi-closed cat litter boxes help keep the indoor air fresh. It helps to keep you cool and comfortable.

[0024] Additionally, one or more assembly boards 11 may have a first opening 11 for easy access. 2 is provided (see Figure 6-7). When the cat uses the litter box, it is easy to enter and exit. The first opening 12 is designed to fit the cat's body shape and Consider their behaviour and ensure they can easily and successfully enter and exit the litter box This will improve the comfort of your cat. If the entrance to the cat litter box is too narrow or difficult to find, If the cat is designed like this, it may refuse to use it due to inconvenience or fear. The clearly placed openings and easily identifiable features help your cat quickly adapt to and accept their new litter box. This helps reduce the problem of non-adaptation and defecating everywhere.

[0025] Furthermore, a plurality of locking projections 111 (see FIG. 8) are provided on each side of the assembly board 11. and a locking notch 112 is formed between adjacent locking projections 111. The vertical boards 11 are engaged with the engagement notches 112 via the engagement protrusions 111, and the two are assembled. Achieve this.

[0026] Here, the engagement between the locking projections 111 and the locking notches 112 allows the assembled cardboards 11 to Ensure that the connection is secure and that the paper board does not come loose or become loose due to the cat's movement or the weight of the litter during use. This allows the user to avoid the adhesive or tools from coming off. Assembly can be completed with simple locking without using a screwdriver, and installation and removal are easy. This greatly simplifies the process and improves the convenience of use. At the same time, as a paper product, The toilet itself is environmentally friendly, but the simplicity of the latching design makes it easier to collect and dispose of the product. This will facilitate the implementation of the concept of sustainable development.

[0027] In this embodiment, specifically, the method of using a locking projection 111 and a locking notch 112 is adopted for assembly. However, to meet different user needs or specific application scenarios, other assembly methods are available: You may also consider the formula:

[0028] Slot type assembly: Design a slot and tongue on the edge of the assembly board 11, and insert the tongue into the slot. This method is also easy to assemble, The structure has the advantage of being reliable. Velcro assembly: The assembly board 11 is attached to the appropriate position. Attach the hook and loop sides of the Velcro to the This method is suitable for situations where frequent attachment / detachment or size adjustment is required. Fixing with cable ties: Assemble with soft cable ties or elastic strings. This method binds the paperboard 11 together to form a secure structure. The slack of the cable tie can be adjusted according to actual needs. Assembling: Buttons and buttonholes are placed on the assembly board 11, and the buttons are fastened to the button holes. The fixing is achieved by fitting into a hole. This method requires some positioning during assembly. It may take some skill to align it, but once fixed, the structure is relatively stable.

[0029] Furthermore, the waterproof and dirt-proof paper box 2 is made by folding the waterproof and dirt-proof paper board. (See FIG. 9) The waterproof and stain-resistant paper board is formed on both the left and right sides and the front of the center The back and front sides of the waterproof and stain-resistant paper board are provided with folds. The waterproof and stain-resistant paper board can be folded along the crease, and the center of the waterproof and stain-resistant paper board is The bottom plate 21 is a left plate 23 and a right plate 22 on both sides of the bottom plate 21. The front and rear sides of the box are the front panel 25 and the rear panel 24, respectively. As a part of the structure, the bottom plate 21 provided a stable support surface for the entire structure. The bottom plate 21 is responsible for placing cat litter and excrement on it, ensuring the stability of the cat litter box. The left and right plates 23 and 22 are located on the left and right sides of the bottom plate 21, respectively, and are folded to form a 21. These two boards form the sides of the carton after folding, and are used to store cat litter and scent. The front plate 25 and the rear plate 24 are located on both the front and rear sides of the bottom plate 21, respectively. The front panel 25 and the rear panel 24 are connected to the bottom panel 21 through the fold lines. Forming the front and back of the carton, it not only enhances the structural strength of the carton, but also provides extra waterproofing and dirt prevention. It also provides more functionality.

[0030] Furthermore, the waterproof and stain-resistant paper board is made of waterproof and stain-resistant film that is layered from top to bottom. This waterproof and stain-resistant film includes: The cardboard sheet is made of silicone release film and is E-flute cardboard.

[0031] The waterproof and stain-resistant film is the top layer, and its main role is to The split prevents liquids such as cat litter and urine from penetrating the paper board, while also preventing the cat litter from contacting the paper board. This example uses a silicone release film. This material has excellent waterproof, oil-proof and stain-resistant properties, and effectively prevents liquid penetration. This effectively prevents cat litter from getting inside the house and reduces the amount of litter left behind.

[0032] The coated paper is placed between the waterproof and dirt-resistant film and the cardboard sheet. Coated paper has a smooth, firm surface that provides some cushioning and strengthening. This helps to maintain the flatness and stability of the waterproof and stain-resistant film.

[0033] The cardboard sheet is the bottom layer, and the cardboard sheet is the bearing part in the paperboard structure. In this example, E-flute corrugated cardboard is used, which has a relatively high durability. It has pressure and cushioning properties, and can withstand the weight of cat litter and cats without deformation. It also has some soundproofing and heat insulation effects, reducing the spread of odors and noise within the cat litter tray. Useful.

[0034] Therefore, overall, the paper material itself is recyclable and fits the eco-friendly concept. At the same time, each layer of material in the multi-layer structure design is recycled and processed separately to maximize resource utilization. Compared to conventional plastic cat litter boxes, it is waterproof and stain-resistant. Our paper cat litter boxes are functional and practical, yet offer lower costs and better cost performance. It has performance.

[0035] Furthermore, the front panel 25 has a second notch (see FIG. 9) aligned with the first opening 12. The second notch in the front panel 25 is aligned with the first opening 12 on the assembly cardboard 11. This provides a wider and smoother path for cats to get in and out of the litter box. When defecating, the urine passes through this opening without any obstruction, and the opening is too small or in the wrong place. By reducing the hassle caused by this, we have improved the comfort of the cat. The design of the cutout also takes into consideration the overall aesthetics, creating a unified visual effect with the first opening 12. This will make the cat litter box look cleaner and more harmonious.

[0036] To fully verify the performance of waterproof and stain-resistant paper cat litter boxes, we tested the following series: We have designed and conducted tests to verify that the product is waterproof, stain-resistant, and easy to clean. This is scientifically rigorously proven.

[0037] 1. Waterproof performance test (see Figure 1) Test purpose: To evaluate the waterproof ability of waterproof and stain-resistant paper box 2.

The waterproof and stain-resistant film layer on the surface has stain-resistant properties, preventing the adhesion of substances such as cat feces. Effective prevention of adhesion has been shown to make the cleaning process easier and more efficient.

[0049] 5. Comparative stain adhesion prevention test (see Figure 5) Test purpose: Compare cat litter boxes made of conventional materials (e.g., plastic) to determine whether they are waterproof and stain-resistant. Test whether the surface of the anti-adhesion paper box 2 has an advantage in preventing the adhesion of cat feces. .

[0050] Test method: Waterproof and stain-resistant paper box 2 with a surface similar to conventional plastic material The cat litter boxes were used as comparison samples. Both were kept clean and free of soiling before testing. The surface of a conventional plastic cat litter box is coated with the same amount of simulated cat feces material (e.g., white Toothpaste) was spread evenly on each surface.

[0051] A conventional plastic cat litter box was left standing for 10 minutes under the same conditions to measure the amount of feces during actual use. The same cat blade or spatula was used to simulate the residual situation. The toilet surface was cleaned with simulated feces to ensure the fairness of the test results. The force was kept constant during cleaning.

[0052] Observation and Recording: After cleaning is completed, the cleaning effect of the conventional plastic cat litter box surface is verified. Observations were made and recorded on the sword.

[0053] Test results: Traditional plastic cat litter boxes showed relatively high adhesion during cleaning. The stool (toothpaste) was simulated and left obvious residue and marks on the plastic surface. To remove it forcefully, you will need to scratch it repeatedly.
