Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Those skilled in the art should also recognize that the embodiments described in the specification are optional embodiments, and the actions and modules involved are not necessarily essential to this invention.

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] refer to Figure 1 as well as Figure 2 As shown, the temperature-changing bathroom sticker according to an embodiment of the present invention includes a base layer 100, a content layer 200, a transparent isolation layer 300, and an anti-slip layer 400 connected sequentially from top to bottom. An adhesive layer 500 is connected to the side of the base layer 100 away from the content layer 200. The content layer 200 is provided with a thermosensitive area 210 and a fluorescent area 220, respectively. The thermosensitive area 210 occupies 10%-30% of the content layer, and the fluorescent area 220 occupies 10%-30% of the content layer. The thermosensitive area 210 is filled with a thermosensitive color-changing material, and the fluorescent area 220 is filled with a fluorescent material. The transparent isolation layer 300 covers the content layer 200 and forms a seal between the two.

[0029] In practical use, by setting thermosensitive color-changing materials and fluorescent materials in the content layer 200, it can provide temperature indication of bathroom water and provide a positioning light source in the dark environment of the bathroom. At the same time, the content layer 200 is covered and sealed by the transparent isolation layer 300, thereby improving the sealing performance of the content layer 200 and improving the overall durability.

[0030] Specifically, the thermal region 210 and the fluorescent region 220 account for the proportion of the content layer in terms of area.

[0031] In some specific embodiments of this utility model, it may also have the following additional technical features: the content layer 200 further includes a graphic area 230, which occupies 40%-60% of the content layer. The graphic area 230, the thermally sensitive area 210, and the fluorescent area 220 form a pattern. The graphic area 230 can be decorated with elements such as flowers, geometric shapes, or text by printing or embedding, making the temperature-changing bathroom sticker both practical and aesthetically pleasing. In this process, the thermally sensitive area 210 and the fluorescent area 220 are cleverly integrated into the pattern. For example, the thermally sensitive area 210 constitutes a part of the pattern, and the color of this part changes when the temperature changes, thereby dynamically updating the appearance of the pattern; the fluorescent area 220 emits light in the dark, enhancing the visual effect of the pattern; for example, reference Figure 2 As shown, a relatively simple circular pattern is used as the graphic area 230, and thermal areas 210 and fluorescent areas 220 are arranged at intervals around the graphic area 230.

[0032] Alternatively, in one specific embodiment, the heat-sensitive area 210 can be designed in the shape of a petal, changing the color of the entire flower as the water temperature changes; the fluorescent area 220 can be arranged in the shape of a leaf outline, creating a luminous effect in the dark. This design not only enhances the decorative value of the product but also makes the temperature indication and light source positioning more intuitive and easy to understand through patterned layout, allowing users to quickly grasp its function without special training. The material of the graphic area 230 is usually consistent with the main body of the content layer 200 to ensure overall harmony, while its design can take user preferences into account, providing personalized options so that the temperature-changing bathroom sticker can blend into different bathroom decoration styles.

[0033] To achieve the above effects, the thermal zone 210 is printed with reversible thermochromic ink. The core of this ink is microencapsulated thermochromic pigment, whose color-changing range can be set according to bathroom safety requirements: it displays a safe blue or green below 30°C; it gradually turns yellow or light green in the comfortable 30°C to 40°C range; it turns into a warning orange or pink at 40°C to 45°C; and it displays a bright red when the temperature exceeds the burn threshold of 45°C.

[0034] The fluorescent area 220 uses fluorescent ink, which employs rare-earth-doped aluminate fluorescent material as the phosphor. This material can continuously emit light for several hours in the dark after absorbing ambient light, exhibiting high initial brightness and long afterglow time. The surface of the phosphor is coated with silica before being mixed with a transparent resin binder to form the fluorescent ink, which is then screen-printed onto a predetermined area of ​​the content layer 200.

[0035] All of these materials can be prepared using screen printing technology, resulting in high pattern resolution, clear boundaries, and a strong bond with the content layer 200 substrate.

[0036] In some specific embodiments of this utility model, it may also have the following additional technical features: the surface of the anti-slip layer 400 is provided with an uneven surface, and the surface roughness of the anti-slip layer 400 is 3.2μm to 6.3μm. This uneven structure provides additional friction by increasing the surface roughness, preventing users from slipping and falling on wet floors when using the bathroom.

[0037] Specifically, the anti-slip layer 400 includes an anti-slip main body fixedly connected to the transparent isolation layer 300 and multiple protrusions integrally formed with the anti-slip main body. These protrusions are spaced apart on the anti-slip main body, each protrusion having a conical cross-sectional shape and a smooth, rounded top. The ratio of the length to the height of the base of each protrusion is no greater than 1:2. This protrusion design effectively improves anti-slip performance while avoiding excessive irritation to the feet. The raised and recessed design not only enhances safety but also reduces water accumulation by dispersing water flow, accelerating the drying process and thus inhibiting mold growth.

[0038] In some specific embodiments of this utility model, it may also have the following additional technical features: the bottom of the base layer 100 has multiple adhesive protrusions 110 for improving the connection strength, and the adhesive layer 500 wraps around the adhesive protrusions 110. The adhesive protrusions 110 are evenly distributed on the bottom of the base layer 100, forming an anchor-like structure. When the adhesive layer 500 is applied, it fills the gaps between the protrusions and covers their surfaces, thereby increasing the bonding area and mechanical locking effect. This design significantly improves the adhesion between the adhesive layer 500 and the base layer 100, preventing delamination in humid or temperature-varying environments.

[0039] In some specific embodiments of this utility model, it may also have the following additional technical features: the thickness of the base layer 100 is 0.1mm-0.25mm, the thickness of the inner layer 200 is 0.05mm-0.15mm, the thickness of the transparent isolation layer 300 is 0.05mm-0.1mm, and the thickness of the anti-slip layer 400 is 0.1mm-0.15mm.

[0040] In some specific embodiments of this utility model, it may also have the following additional technical features: the base layer 100, the inner layer 200, and the transparent isolation layer 300 are all made of plastic. The base layer 100 uses modified polypropylene (PP) material, with its melt flow index controlled at 18-22 g / 10min, ensuring both injection molding fluidity and sufficient rigidity. The inner layer 200 uses polyethylene (PE) substrate, whose excellent flexibility ensures that heat-sensitive and fluorescent materials will not crack when the temperature changes. The transparent isolation layer 300 uses high-transparency TPU material, with a light transmittance of over 92% and good anti-yellowing properties.

[0041] In some specific embodiments of this utility model, it may also have the following additional technical features: the anti-slip layer 400 is made of transparent plastic. Specifically, it uses toughened polycarbonate (PC) material, with a transparency maintained above 88%, ensuring that the pattern and functional display of the inner layer 200 are not affected. This material, by adding nano-level anti-scratch agents, achieves a surface hardness of 2H pencil hardness, effectively resisting daily wear and tear. The anti-slip layer 400 and the transparent isolation layer 300 are bonded using a co-extrusion process, with an interface bonding strength exceeding 3.5 MPa, preventing delamination.

[0042] In some specific embodiments of this utility model, it may also have the following additional technical features: a release layer 600 is attached to the side of the adhesive layer 500 away from the base layer 100. In this embodiment, the release layer can be made of silicone paper or plastic film, protecting the adhesive layer 500 from contamination or oxidation before use and ensuring maximum initial adhesion. When the user is ready to install, simply peel off the release layer to expose the adhesive layer 500 for pasting. This design simplifies the installation process and prevents dust from adhering to the adhesive layer 500 during storage or transportation, thereby maintaining long-term reliability.

[0043] The manufacturing process of temperature-controlled bathroom stickers:

[0044] Phase 1: Substrate Preparation and Functional Layer Coating

[0045] Extrusion calendering of base layer 100:

[0046] Process: Extrusion calendering method is used. Modified polypropylene plastic granules are fed into a single-screw extruder for melt plasticization.

[0047] Molding: Molten PP is extruded into an initial sheet, which then enters the calendering rolls. By controlling the gap, temperature and speed between each calendering roll, the molten sheet is rolled and cooled to the target thickness. After passing through the final calendering roll, it passes through the embossing roll to form an adhesive protrusion 110 structure on the bottom of the substrate.

[0048] Winding: After molding and cooling, the base layer 100 film is wound into a large roll for use in subsequent processes.

[0049] Precision printing of content layer 200:

[0050] Substrate preparation: The 200 substrate for the content layer is also prepared by extrusion calendering and then unwound and corona treated to improve ink adhesion.

[0051] Functional printing: Using a roll-to-roll screen printing machine, printing is performed sequentially:

[0052] First, print the fluorescent area 220: using prepared rare earth aluminate fluorescent ink.

[0053] Secondly, for the printed graphic area 230: use ordinary decorative inks that are water-resistant and weather-resistant.

[0054] Finally, overprint the thermal area 210: using reversible thermochromic microcapsule ink.

[0055] Curing: After each color is printed, it is immediately passed through an ultraviolet (UV) curing station or hot air drying tunnel to instantly cure the ink, avoid color mixing and ensure the clarity and durability of the printed pattern.

[0056] Phase Two: Multilayer Composites and Post-Processing

[0057] Co-extruded composite of transparent isolation layer 300:

[0058] Process: This is key to achieving a perfect seal in an ultra-thin structure. A multi-layer co-extrusion casting composite process is employed. High-transparency TPU particles for the transparent separator layer 300 are melted in another extruder, while the pre-printed content layer 200 substrate is unwound as a "carrier".

[0059] Lamination: Molten TPU is coated onto the printed surface of the inner layer 200 as a molten film. With the help of a large-diameter cooling roller, the TPU film and the inner layer 200 are instantly thermally fused and cooled to form a transparent insulating layer 300. This process achieves seamless coverage and permanent sealing of the inner layer 200.

[0060] Anti-slip layer 400 hot-pressed composite:

[0061] Preparation: The anti-slip layer 400 is pre-processed with a textured surface by chemical etching or embossing rollers.

[0062] Lamination: The anti-slip layer 400 and the semi-finished product that has been laminated with the "inner layer 200-transparent isolation layer 300" are fed into a hot press laminating machine. The anti-slip layer 400 and the transparent isolation layer 300 are firmly laminated together using a transparent hot melt adhesive film or by local hot melting of the surface PC.

[0063] Phase 3: Final Processing

[0064] Adhesive and coating:

[0065] Flip the laminated product over so that the back of the base layer is facing up.

[0066] The medical-grade acrylic pressure-sensitive adhesive is evenly applied to the back of the base layer 100 using a coating head, and then immediately covered with a release layer 600 (glassine paper). Finally, a rubber roller is used to ensure that there are no air bubbles.

[0067] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
