Description

Technical Field

[0001] This utility model relates to the field of toilet accessories, specifically to a seat ring with temperature-sensitive color change. Background Technology

[0002] Toilets are a common bathroom fixture, and after years of development and improvement, they offer many user-friendly functions, greatly facilitating the needs of daily life. To ensure comfortable use in cold environments, toilet seats are designed with a heated structure, such as an internal heating element. The heat generated by this element is conducted to the seat, bringing its surface temperature close to body temperature. However, if the heating function is activated before use, the seat needs time to heat up. While waiting, users may touch the seat to check if it has reached the set temperature, which is inconvenient, and the psychological effect of touching it necessitates handwashing afterwards. Alternatively, adding a temperature display to the toilet would increase costs. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a seat ring with temperature-sensitive color-changing properties.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: A thermochromic seat ring includes a seat ring body with a heating function, and a thermochromic sticker is attached to the seat ring body. The thermochromic sticker includes a thermochromic layer and a light-transmitting surface layer. The thermochromic layer is a reversible thermochromic layer, and the light-transmitting surface layer is attached to the upper surface of the thermochromic layer.

[0005] Furthermore, the light-transmitting surface layer is a transparent thin film layer.

[0006] Furthermore, the light-transmitting surface layer is a hydrophobic transparent thin film layer.

[0007] Furthermore, the temperature-sensitive color-changing sticker is affixed to the surface of the seat cushion of the seat ring body.

[0008] Furthermore, the thermochromic sticker also includes a seating sensing layer, which is disposed at the bottom of the thermochromic layer.

[0009] Furthermore, the sensing end of the seating sensing layer is a capacitive sensor; the sum of the thicknesses of the light-transmitting surface layer and the thermochromic layer is less than 5 mm.

[0010] Furthermore, the thermochromic sticker also includes an insulating layer, which is disposed between the thermochromic layer and the seating sensing layer.

[0011] Furthermore, the sensing end of the seating sensing layer is a capacitive sensor; the sum of the thicknesses of the light-transmitting surface layer, the thermochromic layer, and the insulating layer is less than 5 mm.

[0012] The technical solution provided by this utility model has the following beneficial effects: A thermochromic sticker is installed on the seat ring body. The thermochromic layer of the sticker changes color by sensing the temperature of the seat ring body. When the temperature of the seat ring body reaches the preset temperature (i.e., close to human body temperature), the thermochromic layer will change color, allowing the user to intuitively confirm the heating status of the seat ring. The light-transmitting surface layer serves as an isolation and protection layer to prevent wear and tear on the thermochromic layer. Attached Figure Description

Detailed Implementation

[0014] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0015] In the description of this utility model, terms such as "upper", "lower", "left", "right", "front", and "rear" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] Example 1 Reference Figures 1 to 2As shown, this embodiment provides a seat ring with thermochromic properties, including a seat ring body 100 with a heating function. Specifically, the seat ring body 100 with the heating function has an existing structure, such as an electric heating wire or similar structure inside the seat ring body 100. A thermochromic sticker 10 is also attached to the seat ring body 100. Specifically, the thermochromic sticker 10 can be circular or square and is attached to the seat ring body 100. The thermochromic sticker 10 includes a thermochromic layer 1 and a light-transmitting surface layer 2. The thermochromic layer 1 is a reversible thermochromic layer, i.e., it is prepared using a reversible thermochromic material in the prior art. The light-transmitting surface layer 2 is attached to the upper surface of the thermochromic layer 1.

[0018] A thermochromic sticker 10 is installed on the seat body 100. The thermochromic layer 1 of the thermochromic sticker 10 changes color by sensing the temperature of the seat body 100. For example, when the temperature of the seat body 100 reaches a preset temperature (i.e., close to human body temperature), the thermochromic layer 1 will change color, allowing the user to intuitively confirm the heating status of the seat. This eliminates the need for touch sensing and the addition of a temperature display or other structures to the toilet, making it convenient and cost-effective. The light-transmitting surface layer 2 serves as an insulating and protective layer, preventing wear and tear on the thermochromic layer 1.

[0019] Specifically, the thermochromic layer uses reversible thermochromic materials from existing technologies. When the temperature rises to the set temperature, the thermochromic layer will change color (e.g., turn black), and when the temperature drops below the set temperature, it will revert to its original color (e.g., turn white), thus achieving reversibility and reusability.

[0020] Specifically, the thermochromic layer can be prepared on the lower surface of the translucent surface by means of spraying or other methods.

[0021] Specifically, to better adhere to the seat body 100, an adhesive layer can be provided at the bottom of the thermochromic sticker 10, which is then adhered to the seat body 100 via the adhesive layer. Of course, other methods can also be used for adhesion.

[0022] Specifically, in this embodiment, the light-transmitting surface layer 2 is a transparent thin film layer with a thickness of millimeters or micrometers, and is further a hydrophobic film, such as a polytetrafluoroethylene (PTFE) film, to prevent water vapor or water droplets from accumulating on the surface of the light-transmitting surface layer and affecting the temperature-sensitive color-changing layer 1.

[0023] The surface of the translucent layer 2 can be decorated with graphics or text, such as descriptions of the colors before and after low-temperature color change, to better help users confirm relevant information. The goal is simply to allow users to observe the color of the thermochromic layer 1 through the translucent layer 2.

[0024] Furthermore, in this embodiment, the temperature-sensitive color-changing sticker 10 is affixed to the seat cushion surface 101 of the seat ring body 100. The seat cushion surface 101 of the seat ring body 100 is used to contact human skin. By setting it in this location, the heating status of the seat ring body 100 can be more accurately confirmed.

[0025] Example 2 This embodiment provides a seat ring with temperature-sensitive color-changing function, which, based on the seat ring with temperature-sensitive color-changing function provided in Embodiment 1, further adds the following structure: (Refer to...) Figure 3 As shown, the thermochromic sticker 10 also includes a seating sensing layer 3, which is disposed at the bottom of the thermochromic layer 1. The seating sensing layer 3 is used to sense whether someone has sat down. The seating sensing of the seating sensing layer 3 is existing technology and can be implemented directly using existing structures, such as a capacitive seating sensing structure, that is, the sensing end of the seating sensing layer 3 is a capacitive sensor. Its specific structure and working principle will not be detailed here. The light-transmitting surface layer 2 simultaneously isolates and protects the thermochromic layer 1 and the seating sensing layer 3.

[0026] Furthermore, since the seating sensing layer 3 adopts a capacitive seating sensing structure, in order to ensure that it can be effectively sensed, in this embodiment, the thickness of the covering layer above the seating sensing layer 3 (in this embodiment, the sum of the thicknesses of the thermochromic layer 1 and the light-transmitting surface layer 2) should be less than 5mm.

[0027] Example 3 This embodiment provides a seat ring with temperature-sensitive color-changing function, which, based on the seat ring with temperature-sensitive color-changing function provided in Embodiment 2, further adds the following structure: (Refer to...) Figure 4 As shown, the thermochromic sticker 10 also includes an insulating layer 4, which is disposed between the thermochromic layer 1 and the seating sensing layer 3. The insulating layer 4 provides separate isolation and protection for the seating sensing layer 3 to prevent any possible mutual interference between the thermochromic layer 1 and the seating sensing layer 3.

[0028] Specifically, the insulating layer 4 is insulating, such as by using an insulating film from existing technologies.

[0029] Furthermore, since the seating sensing layer 3 adopts a capacitive seating sensing structure, in order to ensure that it can be effectively sensed, in this embodiment, the thickness of the covering layer above the seating sensing layer 3 (in this embodiment, it is the sum of the thicknesses of the light-transmitting surface layer 2, the thermochromic layer 1, and the insulating isolation layer 4) should be less than 5mm.

[0030] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
