Description

Technical Field

[0001] This application relates to the field of packaging box technology, and in particular to a highly efficient moisture-proof coating structure for the inner wall of a cat litter box. Background Technology

[0002] Cat litter boxes are paper containers used to package cat litter. The paper material is relatively lightweight, making it convenient for consumers to carry and move cat litter, especially for large packages. The design of the boxes makes them easy to lift and move. The surface of the boxes is suitable for various printing and decorations, which can display information such as the brand, features, and instructions for use of the cat litter, attracting consumers' attention and playing a good role in publicity and promotion. They are mainly used to hold and protect cat litter, preventing it from being damaged, damp, or leaking during transportation, storage, and sales, and ensuring the quality and hygiene of the cat litter.

[0003] In addition, the existing patent publication number CN220518835U discloses a paper box packaging with moisture-proof function. The above device does not set up any special moisture-proof device for the bottom of the paper box, which is a key part that is easily exposed to ground moisture. It only mentions that the overall moisture-proof work is undertaken by each layer. The moisture-proof effect of the contact surface between the bottom and the bottom surface of the box is not good. Therefore, this solution proposes a high-efficiency moisture-proof coating structure for the inner wall of a cat litter box. Utility Model Content

[0004] To improve the problem of unsatisfactory moisture-proof effect on the contact surface between the bottom and the bottom of the box, this application provides a high-efficiency moisture-proof coating structure for the inner wall of a cat litter box.

[0005] The technical solution for the high-efficiency moisture-proof coating structure on the inner wall of a cat litter box provided in this application is as follows:

[0006] A highly efficient moisture-proof coating structure for the inner wall of a cat litter box includes a base plate, a fixed frame fixedly installed on the top of the base plate, a second rectangular groove opened above the fixed frame on the top of the base plate, a fixed plate symmetrically fixedly connected to the bottom center of the second rectangular groove, a montmorillonite desiccant for dehumidification locked between the two fixed plates, vertical plates symmetrically fixedly connected to the four corners of the top of the fixed frame, a rectangular cavity communicating with the second rectangular groove opened inside the vertical plate, and a connecting hole communicating with the rectangular cavity opened at equal intervals on one side of the multiple vertical plates.

[0007] By adopting the above technical solution, the base plate provides a supporting foundation for the overall structure, the fixed frame is used to connect other components, and the montmorillonite desiccant fixed by the two fixed plates in the second rectangular groove plays a dehumidifying role, absorbing moisture in the surrounding environment. The vertical plates at the top four corners of the fixed frame have internal rectangular cavities that are connected to the second rectangular groove. Air can enter through equidistant connecting holes on the vertical plates that are connected to the rectangular cavities, allowing air to circulate throughout the entire structure. This promotes full contact between the moisture and the montmorillonite desiccant, enhancing the dehumidification effect and thus improving the moisture-proof performance of the inner wall of the cat litter box, protecting the cat litter inside from moisture and deterioration.

[0008] Preferably, the two ends of the fixed frame are fixedly installed with support cross plates above the inner side between the two vertical plates to increase the support strength of the box.

[0009] By adopting the above technical solution, the supporting horizontal plate installed on the upper inner side between the two vertical plates at both ends of the fixed frame mainly serves to increase the overall support strength of the cat litter box.

[0010] Preferably, trapezoidal grooves are symmetrically formed at both ends of the bottom of the base plate.

[0011] By adopting the above technical solution, the trapezoidal groove is used to connect other components.

[0012] Preferably, the bottom of the base plate is engaged with a base, and the top two ends of the base are symmetrically fixedly connected with trapezoidal protrusions corresponding to the trapezoidal grooves.

[0013] By adopting the above technical solution, the trapezoidal protrusions symmetrically arranged at both ends of the top of the base are engaged with the trapezoidal groove at the bottom of the base plate. This achieves a stable assembly of the base plate and the base, making the connection between the two tighter and enhancing the stability of the entire cat litter box structure. On the other hand, this engagement method facilitates the disassembly and installation of the base and the base plate.

[0014] Preferably, the bottom of the base has a first rectangular groove that communicates with the outside at equal intervals, and rectangular grooves for moving the base are symmetrically formed in the middle of the two sides of the bottom of the base.

[0015] By adopting the above technical solution, the first rectangular grooves that are equidistantly opened at the bottom of the base and communicate with the outside can allow air to circulate between the base and the placement surface, avoiding the accumulation of moisture between the base and the placement surface due to the humid environment, thus playing a moisture-proof role and reducing the risk of the base and cardboard box getting damp. The rectangular grooves that are symmetrically opened in the middle of both sides of the bottom of the base for moving the base make it convenient for users to insert their fingers or tools into the grooves to apply force when they need to move the cat litter box.

[0016] Preferably, a waterproof layer is bonded to the top of the base, and the waterproof layer is compressed at the connection between the trapezoidal protrusion and the trapezoidal groove to form an inverted trapezoid.

[0017] By adopting the above technical solution, the waterproof layer bonded to the top of the base can effectively prevent moisture from entering from the bottom, ensuring the moisture-proof performance of the cat litter box in all aspects. The waterproof layer embedded in the trapezoidal groove can effectively prevent moisture from leaking out from the trapezoidal groove.

[0018] Preferably, a box body is fitted onto the top of the base plate, and rectangular holes are opened at the four corners of the bottom of the box body corresponding to the vertical plate. The innermost layer of the outer peripheral surface of the box body is coated with polyurethane primer, the outer layer of the polyurethane primer is coated with polyurethane intermediate coat, and the outer layer of the polyurethane intermediate coat is coated with polyurethane topcoat.

[0019] By adopting the above technical solution, the outer peripheral surface of the box is coated with polyurethane primer, polyurethane intermediate coat and polyurethane topcoat from the inside to the outside. The polyurethane primer can adhere tightly to the box surface and enhance the adhesion between the coating and the box. The polyurethane intermediate coat can increase the coating thickness and improve the protective performance and impact resistance. The polyurethane topcoat provides good weather resistance, wear resistance and water resistance, preventing external moisture, dust and other factors from corroding the box and internal structure. At the same time, it makes the box look more beautiful and extends the service life of the box and the cat litter box as a whole.

[0020] Preferably, a cover is fitted onto the top of the box.

[0021] By adopting the above technical solution, the cover that fits onto the top of the box mainly serves to provide a closed protection for the cat litter box.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The overall support strength is enhanced by the cooperation of the bottom plate, the top fixed frame, the vertical plate and the supporting horizontal plate to prevent the cardboard box from deforming. At the same time, the montmorillonite desiccant in the second rectangular groove dehumidifies through air circulation, the outer perimeter of the box is protected by a multi-layer coating, and the cover further blocks moisture. In addition, the effective moisture-proof measures at the bottom improve the stability and moisture-proof performance of the cat litter box from the overall structure and the synergistic effect of each part.

[0024] 2. The waterproof layer at the top of the base is squeezed into an inverted trapezoid shape at the connection between the trapezoidal protrusion and the trapezoidal groove connected to the base plate, which fits tightly against the bottom surface of the base plate. This effectively prevents moisture from entering from the bottom. In addition, the first rectangular groove at the bottom of the base promotes air circulation and reduces the risk of moisture. These special moisture-proof designs for the bottom make up for the shortcomings of existing patents in moisture-proofing the bottom of cardboard boxes and improve the moisture-proofing effect of the bottom.

[0035] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0036] The device's "up, down, left, right" perspectives are... Figure 1 The orientation of the attached diagram is the reference.

[0037] This application discloses a highly efficient moisture-proof coating structure for the inner wall of a cat litter box.

[0038] Reference Figure 1 , Figure 3 , Figure 4As shown, a high-efficiency moisture-proof coating structure for the inner wall of a cat litter box includes a base plate 3. A fixing frame 302 for increasing the support strength of the box body 4 is fixedly installed at the top center of the base plate 3. A second rectangular groove 303 for storage is opened above the fixing frame 302 at the top of the base plate 3. Fixing plates 304, which are bonded to the fixing frame 302 at both ends, are symmetrically fixedly connected to the bottom center of the second rectangular groove 303. The thickness of the fixing plates 304 is half the depth of the second rectangular groove 303. A montmorillonite desiccant 305 for dehumidification is installed in the groove between the two fixing plates 304. The montmorillonite desiccant 305 is packaged in a bag and is cheaper than other similar desiccants, but the effect is not much different. The four corners of the top of the fixing frame 302 are symmetrically fixedly connected to a tool for lifting. The box 4 is supported by a vertical plate 306. The vertical plate 306 has a rectangular cavity 307 inside, which is connected to the internal space of the second rectangular groove 303. Multiple vertical plates 306 have equidistant connecting holes 308 on one side, which are connected to the internal space of the rectangular cavity 307. The two ends of the fixed frame 302 are fixedly installed on the upper inner side between the two vertical plates 306, and the supporting horizontal plate 309 is used to increase the support strength of the box 4. The bottom of the base plate 3 has trapezoidal grooves 301 symmetrically opened at both ends for connecting other components. The bottom of the base plate 3 is engaged with a base 1 whose side surface is flush with the side surface of the base plate 3. The top of the base 1 has trapezoidal protrusions 103 symmetrically fixed at both ends, and the trapezoidal protrusions 103 are engaged with the trapezoidal grooves 301.

[0039] The base plate 3 serves as the basic support structure. The top fixed frame 302, vertical plate 306, and supporting horizontal plate 309 work together to enhance the overall support strength and prevent the cardboard box from deforming. The second rectangular groove 303 is used to store montmorillonite desiccant 305. The montmorillonite desiccant 305 in the groove between the two fixed plates 304 plays a dehumidifying role. The space inside the box 4 is connected to the second rectangular groove 303 through the connecting hole 308 on the vertical plate 306 and the rectangular cavity 307, so that the moisture inside the box is absorbed and circulated by the montmorillonite desiccant 305 to achieve moisture prevention. The base 1 is connected to the trapezoidal groove 301 at the bottom of the base plate 3 by the trapezoidal protrusion 103 at the top, which not only stabilizes the overall structure, but the waterproof layer 2 at the top of the base 1 further prevents moisture from entering from the bottom. When the base 1 is wet, it can be removed by separating the trapezoidal protrusion 103 from the base plate 3 to prevent the box 4 from being contaminated. The first rectangular groove 101 at the bottom of the base 1 promotes air circulation and reduces the risk of moisture.

[0040] Reference Figure 2 , Figure 5 , Figure 6As shown, the bottom of the base 1 has equidistant first rectangular grooves 101 communicating with the outside. Rectangular recesses 102 for moving the box 4 are symmetrically formed on both sides of the bottom of the base 1. A waterproof layer 2 is bonded to the top of the base 1. The waterproof layer 2 is located between the trapezoidal protrusion 103 and the trapezoidal groove 301, and the connection between the trapezoidal protrusion 103 and the trapezoidal groove 301 is compressed to form an inverted trapezoid. The waterproof layer 2 is bonded to the bottom surface of the base plate 3, and a box is fitted onto the top of the base plate 3. The box body 4 has rectangular holes 404 at the four corners of its bottom. The rectangular holes 404 are inserted into the vertical plate 306. The top surfaces of the vertical plate 306 and the supporting horizontal plate 309 are flush with the top surface of the box body 4. The innermost layer of the outer peripheral surface of the box body 4 is coated with polyurethane primer 401. The outer layer of the polyurethane primer 401 is coated with polyurethane intermediate coat 402. The outer layer of the polyurethane intermediate coat 402 is coated with polyurethane topcoat 403. The top of the box body 4 is fitted with a cover 5 whose outer side is flush with the outer side of the bottom plate 3.

[0041] The base 1 serves as the basic support component. The first rectangular grooves 101, evenly spaced at the bottom, allow air circulation between the base 1 and the placement surface, effectively preventing moisture accumulation and reducing the risk of dampness. The rectangular grooves 102 on both sides facilitate easy movement of the cardboard box by inserting fingers or tools. The waterproof layer 2, adhered to the top, is compressed at the connection between the trapezoidal protrusion 103 and the trapezoidal groove 301, forming an inverted trapezoid that tightly adheres to the bottom surface of the base plate 3. This enhances the seal between the base 1 and the base plate 3, preventing moisture from penetrating from the bottom. After the base plate 3 and base 1 are securely connected, the top... The box body 4 is fitted with a rectangular hole 404 at the four corners of the bottom of the box body 4, which is inserted into the vertical plate 306. The vertical plate 306 and the supporting horizontal plate 309 jointly support the box body 4 to ensure structural stability. The outer periphery of the box body 4 is coated with polyurethane primer 401, polyurethane intermediate coat 402 and polyurethane topcoat 403 in sequence. The primer enhances the adhesion of the coating, the intermediate coat improves protection and impact resistance, and the topcoat provides good weather resistance, wear resistance and water resistance, further protecting the box body 4 from external corrosion. Finally, the cover 5 fitted on the top of the box body 4 prevents dust and debris from falling in and further blocks moisture from entering.

[0042] It should be noted that polyurethane primer 401 has strong adhesion to the cardboard box surface, penetrating deep into the cardboard fibers to form a firm bond. It has excellent chemical resistance and abrasion resistance, enhancing the protective ability of the cardboard box surface and providing a stable adhesion interface for subsequent coatings. Polyurethane intermediate coat 402 further improves the waterproof performance and strength of the coating. It has good elasticity and flexibility, adapting to the expansion and contraction of the cardboard box in different environments and preventing the coating from cracking. At the same time, the intermediate coat also enhances the impact resistance of the entire coating system. Polyurethane topcoat 403 provides durable waterproof protection and an aesthetically pleasing appearance. It has high gloss and good weather resistance, resisting the erosion of natural factors such as ultraviolet rays and rain, extending the service life of the coating.

[0043] The implementation principle of the high-efficiency moisture-proof coating structure for the inner wall of a cat litter box in this application embodiment is as follows: The base plate 3 serves as the basic support structure, cooperating with the top fixed frame 302, vertical plate 306, and supporting horizontal plate 309 to enhance the overall support strength and prevent the box from deforming. The second rectangular groove 303 is used to store moisture-proof materials. The montmorillonite desiccant 305 in the groove between the two fixed plates 304 plays a dehumidifying role. Air enters the rectangular cavity 307 through the connecting hole 308 on the vertical plate 306, and then flows into the second rectangular groove 303, realizing air circulation inside the box. This allows the moisture to fully contact the montmorillonite desiccant 305, thereby absorbing the moisture. The trapezoidal protrusion 103 on the top of the base 1 and the base plate... The trapezoidal groove 301 at the bottom of the base plate 3 engages and connects to stabilize the overall structure. The top waterproof layer 2 is squeezed into an inverted trapezoid at the connection point, closely adhering to the bottom surface of the base plate 3, effectively preventing moisture from entering from the bottom. The first rectangular groove 101 at the bottom of the base plate 1 promotes air circulation and reduces the risk of moisture. After the base plate 3 is connected to the base plate 1, the top is fitted with the box body 4. The rectangular holes 404 at the four corners of the bottom of the box body 4 are inserted into the vertical plate 306 and supported by the vertical plate 306 and the supporting horizontal plate 309. The primer, intermediate coat and top coat on the outer periphery of the box body 4 respectively enhance adhesion, improve protection and impact resistance, and provide weather resistance, wear resistance and waterproofness. Finally, the top of the box body 4 is fitted with a cover 5 to prevent dust and debris from falling in and further block moisture.

[0044] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
