Description

Technical Field

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

[0002] As society progresses, toilets are becoming increasingly functional, with features such as heated seats, seat sensors, and automatic flushing. These advancements bring greater convenience to people's lives. However, in current technology, heated seats require a certain amount of time to heat up. Users typically need to touch the seat to check if it has reached the set temperature, which is cumbersome, and the psychological need to wash hands afterward is understandable. Adding a temperature display to the toilet would also increase costs. Utility Model Content

[0003] Therefore, this utility model provides a seat-sensing sticker with temperature-sensitive color change, which integrates the functions of seat-sensing and temperature-sensitive color change. When applied to the toilet seat, it allows users to intuitively confirm the heating status of the seat.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: This solution provides a temperature-sensitive color-changing seating sensor sticker, comprising a seating sensing layer, an insulating layer, and a temperature-sensitive color-changing layer. The insulating layer is disposed above the seating sensing layer, and the temperature-sensitive color-changing layer is a reversible temperature-sensitive color-changing layer, disposed above the insulating layer.

[0005] Furthermore, a light-transmitting surface layer is provided above the thermochromic layer.

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

[0007] Furthermore, the light-transmitting surface layer is a hydrophobic film.

[0008] Furthermore, the sensing end of the seating sensing layer is a capacitive sensor; the combined thickness of the insulating layer and the thermochromic layer is less than 5 mm.

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

[0010] Another type of temperature-sensitive color-changing seating sensor provided in this solution includes a seating sensing layer, an insulating layer, and a temperature-sensitive color-changing layer. The insulating layer is disposed above the seating sensing layer, the temperature-sensitive color-changing layer is a reversible temperature-sensitive color-changing layer, the temperature-sensitive color-changing layer is disposed between the insulating layer and the seating sensing layer, and the insulating layer is a light-transmitting layer.

[0011] Furthermore, the sensing end of the seating sensing layer is a capacitive sensor; the combined thickness of the insulating layer and the thermochromic layer is less than 5 mm.

[0012] The technical solution provided by this utility model has the following beneficial effects: The temperature-sensitive color-changing seat sensor sticker provided in this application integrates seat sensing and temperature-sensitive color-changing functions. When applied to toilet seats, the temperature-sensitive color-changing layer can change color by sensing the temperature of the seat. That is, when the seat is heated to a certain temperature, the temperature-sensitive color-changing layer will change color, allowing users to intuitively confirm the heating status of the seat. It is also low in cost. Attached Figure Description

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 Figure 1As shown in the figure, this embodiment provides a temperature-sensitive color-changing seat sensor patch, including a seat sensing layer 1, an insulating layer 2, and a temperature-sensitive color-changing layer 3. The insulating layer 2 is disposed above the seat sensing layer 1, and the temperature-sensitive color-changing layer 3 is a reversible temperature-sensitive color-changing layer, that is, it is prepared using a reversible temperature-sensitive color-changing material. The temperature-sensitive color-changing layer 3 is disposed above the insulating layer 2; that is, the seat sensing layer 1, the insulating layer 2, and the temperature-sensitive color-changing layer 3 are stacked sequentially from bottom to top.

[0018] This seat-sensing sticker is applied to the surface of the toilet seat. The seat-sensing layer 1 detects whether someone is sitting down. This sensing technology is existing and can be implemented using existing structures, such as a capacitive sensor. The specific structure and working principle of the capacitive sensor layer 1 are not detailed here. The insulating layer 2 provides insulation protection for the seat-sensing layer 1 below; for example, an insulating film can be used. The thermochromic layer 3 changes color with temperature. When the seat is heated, the heat is conducted to the thermochromic layer 3. When the temperature reaches a certain value, the thermochromic layer 3 changes color, allowing the user to visually confirm the change without needing to touch it or add a temperature display to the toilet. This thermochromic seat-sensing sticker can be improved by adding a thermochromic layer 3 (and possibly a light-transmitting surface layer 4 as described below), resulting in lower cost and greater practicality.

[0019] Specifically, the thermochromic layer 3 uses a reversible thermochromic material in the existing technology. That is, when the temperature rises to the set temperature, the thermochromic layer 3 will change color (e.g., turn black), and when the temperature drops below the set temperature, it will turn back to its original color (e.g., turn white), thus achieving reversibility and reusability.

[0020] Specifically, the thermochromic layer 3 can be prepared on the upper surface of the insulating layer 2 by means of spraying or other methods.

[0021] Furthermore, a light-transmitting surface layer 4 is disposed above the thermochromic layer 3; this light-transmitting surface layer 4 is used to isolate and protect the thermochromic layer 3, preventing it from being worn. Specifically, in this embodiment, the light-transmitting surface layer 4 is a transparent thin film layer, and more specifically, a hydrophobic thin 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 4 and affecting the thermochromic properties of the thermochromic layer 3.

[0022] Meanwhile, markings and text descriptions can be designed on the upper surface of the light-transmitting layer 4, such as indicating the colors before and after the color change; at least enough to partially display the thermochromic layer 3.

[0023] Of course, in other embodiments, if the thermochromic layer 3 has the characteristics of structural stability and wear resistance, the structure of the light-transmitting surface layer 4 may not be used.

[0024] Specifically, since the seating sensing layer 1 adopts a capacitive seating sensing structure, in order to ensure effective sensing, in this embodiment, the thickness of the covering layer above the seating sensing layer 1 (in this embodiment, the sum of the thicknesses of the insulating isolation layer 2, the thermochromic layer 3, and the light-transmitting surface layer 4) should be less than 5mm. Of course, without the light-transmitting surface layer 4, such as... Figure 2 As shown, the sum of the thicknesses of the insulating layer 2 and the thermochromic layer 3 should be less than 5 mm.

[0025] Specifically, to ensure a better fit on the seat ring, an adhesive layer can be placed at the bottom of the seat sensor sticker, allowing it to adhere to the seat ring. Of course, other methods can also be used for adhesion.

[0026] Example 2 like Figure 3 As shown in the figure, this embodiment provides a temperature-sensitive color-changing seating sensor, including a seating sensing layer 1, an insulating layer 2, and a temperature-sensitive color-changing layer 3. The insulating layer 2 is disposed above the seating sensing layer 1. The temperature-sensitive color-changing layer 3 is a reversible temperature-sensitive color-changing layer, that is, it is prepared using a reversible temperature-sensitive color-changing material. The temperature-sensitive color-changing layer 3 is disposed between the insulating layer 2 and the seating sensing layer 1, and the insulating layer 2 is a light-transmitting layer. That is, the seating sensing layer 1, the temperature-sensitive color-changing layer 3, and the insulating layer 2 are stacked sequentially from bottom to top.

[0027] When using this seat-sensing sticker, it is affixed to the surface of the seat ring. The seat-sensing layer 1 is used to detect whether someone has sat down. The seat-sensing function of this layer is existing technology and can be implemented using existing structures, such as a capacitive seat-sensing structure, where the sensing end of the seat-sensing layer 1 is a capacitive sensor. The specific structure and working principle are not detailed here. The insulating layer 2 protects both the underlying thermochromic layer 3 and the seat-sensing layer 1, and also needs to be light-transmitting to ensure that the user can observe the color change of the thermochromic layer with the naked eye; for example, a transparent insulating film, as used in existing technology, can be used. The thermochromic layer 3 is used for temperature-sensitive color change. When the seat ring is heated, its heat will be conducted to the thermochromic layer. When the temperature reaches a certain value, the thermochromic layer 3 will change color. At this time, the user can intuitively confirm it with the naked eye. There is no need to touch it with your hands or add a temperature display to the toilet. This thermochromic seat sensor sticker can add the thermochromic layer 3 to the original seat sensor sticker. It is low in cost and highly practical.

[0028] Specifically, the thermochromic layer 3 uses a reversible thermochromic material in the existing technology. That is, when the temperature rises to the set temperature, the thermochromic layer 3 will change color (e.g., turn black), and when the temperature drops below the set temperature, it will turn back to its original color (e.g., turn white), thus achieving reversibility and reusability.

[0029] Specifically, the thermochromic layer 3 can be prepared on the lower surface of the insulating layer 2 by means of spraying or other methods.

[0030] Furthermore, the insulating layer 2 is a hydrophobic film to prevent water vapor or water droplets from accumulating on the surface of the insulating layer 2 and affecting the temperature-sensitive color change of the thermochromic layer 3.

[0031] Specifically, 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 insulating isolation layer 2 and the thermochromic layer 3) should be less than 5mm.

[0032] 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.
