[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] Figure 1 The embodiment of the present application provides a smart toilet seat using a carbon fiber heating wire as a heating component, characterized in that it includes a plastic surface layer 11, an aluminum foil 12 within the heating component, and a heating wire 13 within the heating component. The heating wire 13 is fixed to the aluminum foil 12 by ultrasonic welding or thermal welding to form the heating component. The heating component is assembled with the plastic surface layer 11 by adhesive bonding. The heating wire 13 includes a core 21 and an outer layer 22 wrapped around the core.

[0031] The core 21 includes one or more carbon fiber filaments, wherein the carbon fiber filaments are arranged in parallel, or the carbon fiber filaments are spirally wound, or some of the carbon fiber filaments are spirally wound and the remaining carbon fiber filaments are arranged in parallel; the heating wire 13 generates heat when powered on and evenly transfers heat through the aluminum foil 12, and transmits heat to the outside using the plastic surface layer 11 as a medium carrier, and radiates heat to the outside through the core 21 of the heating wire 13 in the form of infrared and / or far infrared rays, so that a person sitting on the plastic surface layer of the toilet seat feels warm and comfortable.

[0032] The core 21 generates far infrared rays with a wavelength of 3 to 16 μm after being energized.

[0033] The core 21 comprises one or more alloy resistance wires, which are arranged parallel to or intertwined with the carbon fiber wires in the core, or some of the alloy resistance wires are spirally wound with the carbon fiber wires in the core, and the remaining alloy resistance wires are arranged in parallel.

[0034] The alloy resistance wire comprises one or more of copper, nickel, chromium, aluminum and iron, and the wire diameter of each alloy resistance wire is 0.02 to 0.50 mm.

[0035] Among them, one section of the core 21 is connected to one or more metal wires, and is wrapped and fixed with an alloy resistance wire so that the metal wire is tightly combined with the core, so that the core current passes directly through the metal wire to form a non-heating core segment, and the non-heating core segment is connected to the power supply; the metal wire of the non-heating core segment is a copper wire or an aluminum wire with a wire diameter of 0.02 to 0.80 mm.

[0036] The heating wire 13 is fixed to the aluminum foil 12 by ultrasonic welding or heat welding, and is attached to the bottom of the plastic surface layer 11 by double-sided tape 34. It is embedded in the plastic bottom layer 35 and fixed by ultrasonic welding, screw mounting, or buckling. Thus, the plastic surface layer 11, the heating wire 13, the aluminum foil 12, the double-sided tape 34, and the plastic bottom layer 35 are combined into a heating seat as a whole.

[0037] Or the heating wire 13 is fixed to the aluminum foil 12 by means of double-sided tape 44, and is attached to the bottom of the plastic surface layer 11 by means of double-sided tape 44, embedded in the plastic bottom layer 35 and fixed by ultrasonic welding, screw mounting or buckling, so that the plastic surface layer 11, the heating wire 13, the aluminum foil 12, the double-sided tape 44 and the plastic bottom layer 35 are combined into a heating seat as a whole;

[0038] Or the heating wire 13 is positioned and installed through the wire groove, embedded in the plastic bottom layer 55 and ultrasonic welding, screw installation, buckle fixation or glue bonding are used to combine the plastic surface layer 11, the heating wire 13 and the plastic bottom layer 55 into a heating seat as a whole;

[0039] The plastic bottom layer 35 and the plastic bottom layer 55 play the role of decoration, support and waterproofing.

[0040] The plastic surface layer 11 , the plastic bottom layer 35 and the plastic bottom layer 55 are made of PP, ABS, urea-formaldehyde, PVC, PE or PC materials.

[0041] Among them, after the plastic surface layer 11 and the heating wire 13 are fixed to the aluminum foil 12, they are pasted and installed by double-sided tape 34, or pasted and installed by double-sided tape 44, or positioned and installed by wire grooves, and then a plastic bottom layer 35 or a plastic bottom layer 55 is formed by secondary injection molding, thereby combining into a heating seat ring as a whole.

[0042] The carbon fiber filaments contained in the core body 21 have a tow specification of 1K to 96K.

[0043] It is understandable that when the carbon fiber filaments are laid out in parallel, they can provide relatively uniform strength and stiffness in the axial direction of the fiber, enhance resistance to tension and pressure in that direction, ensure that the structure has stable performance in that direction, and are less likely to have localized strength deficiencies or stress concentration. Since the direction of the carbon fiber filaments is consistent, the relevant parameters and models are relatively simple and clear when performing structural design and mechanical property calculations. Designers can then more accurately predict the overall strength, stiffness and other mechanical properties of the structure based on the performance and layout direction of the carbon fiber filaments, thereby performing more targeted structural optimization and design, reducing uncertainty and complexity in the design process.

[0044] When the carbon fiber strands are spirally wound and laid, they are distributed in different directions. This gives the structure good strength and rigidity in multiple directions, allowing it to better handle loads from different directions, disperse and withstand stress from all directions, and improve its overall stability and reliability. The spirally wound carbon fiber strands form a mesh-like structure within the structure, which increases the material's toughness and makes it less susceptible to brittle fracture when subjected to external forces. Even if some of the carbon fiber strands are damaged, the overall wound structure remains, allowing the structure to maintain a certain degree of integrity and load-bearing capacity.

[0045] When some of the carbon fiber filaments in each carbon fiber filament are spirally wound and laid out, and the remaining carbon fiber filaments are laid out in parallel, the strength, toughness and isotropic properties of the carbon fiber filament structure in the core can be balanced.

[0046] The core outer cladding 22 is made of silicone, rubber, PVC, PET or PTFE, and the thickness of the outer cladding is 0.10-3.00 mm.

[0047] The materials of the plastic surface layer 11 and the plastic bottom layer 35 and the plastic bottom layer 55 can be PP, ABS, urea-formaldehyde, PVC, PE or PC, and are made by injection molding process.

[0048] Specifically, the heating wire 13 is fixed to the aluminum foil 12 by ultrasonic welding or heat welding, and is attached to the bottom of the plastic surface layer 11 by double-sided tape 34. It is embedded in the plastic bottom layer 35 and fixed by ultrasonic welding, screw installation, or buckling. The plastic surface layer 11, the heating wire 13, the aluminum foil 12, the double-sided tape 34, and the plastic bottom layer 35 are combined into a heating seat as a whole.

[0049] Or the heating wire 13 is fixed to the aluminum foil 12 by the double-sided tape 44, and is pasted and installed on the bottom of the plastic surface layer 11 by the double-sided tape 44, embedded in the plastic bottom layer 35 and fixed by ultrasonic welding or screw installation or buckle fixing, so that the plastic surface layer 11, the heating wire 13, the aluminum foil 12, the double-sided tape 44 and the plastic bottom layer 35 are combined into a heating seat as a whole;

[0050] Or the heating wire 13 is positioned and installed through the wire groove, embedded in the plastic bottom layer 55 and ultrasonic welding, screw installation, buckle fixation or glue bonding are used to combine the plastic surface layer 11, the heating wire 13 and the plastic bottom layer 55 into a heating seat as a whole.

[0051] Specifically, Figure 3 、 Figure 4The heating wire 13 shown can be combined with the aluminum foil 12 and double-sided tape 34 and double-sided tape 44, and then attached to the bottom of the plastic surface layer 11, so that the heating component can be reliably installed inside the plastic surface layer 11, and the heating wire 13 can be arranged in a preset track inside the plastic surface layer 11; the preset track can be spread throughout the plastic bottom layer 11, so that the heating component can heat the plastic surface layer 11 of the heating seat as a whole; the aluminum foil 12 is used to support the paving shape of the heating wire and to balance the heating temperature.

[0052] Specifically, Figure 5 The heating wire 13 shown is installed in the wire groove at the bottom of the plastic surface layer 11 of the heating seat ring, embedded in the plastic bottom layer 55, and is combined into a heating seat ring as a whole by ultrasonic welding, screw installation, buckle fixation or glue bonding.

[0053] Specifically, a secondary injection molding process can also be used. After the plastic surface layer 11, the heating wire 13 and the aluminum foil 12 are fixed, they are then pasted and installed through double-sided tape 34, or pasted and installed through double-sided tape 44, or the heating wire 13 is positioned and installed through a wire groove, and then placed in an injection molding machine for secondary injection molding to form a plastic bottom layer 35 or a plastic bottom layer 55, thereby combining them into a heating seat ring as a whole.

[0054] It can be understood that the core 21 can generate heat after being energized, and transmit heat to the outside through the outer layer 22 and the plastic surface layer 11 as a medium carrier; and the heating component core 21 radiates heat to the outside in the form of infrared and / or far infrared rays, so that the person sitting on the plastic surface layer of the toilet seat feels warm and comfortable.

[0055] In addition, the core 21 emits far infrared rays with a wavelength of 3 to 16 μm. It can be understood that the far infrared rays in this band can have a health-care effect on the human body. The human body absorbs the far infrared rays to effectively promote blood circulation and metabolism, enhance the body's immunity and the tissue regeneration ability of biological cells. Therefore, the toilet seat can be used for human heating and / or health care, etc.

[0056] The toilet seat provided by this embodiment has a plastic surface layer, a heating component, and a plastic bottom layer, which are combined to form a heating seat. When the heating wire is energized, it generates heat and transmits heat to the outside through dielectric conduction, infrared radiation conduction, or far-infrared radiation conduction, thereby making the person sitting on the plastic surface layer of the toilet seat feel warm and comfortable. As can be seen from this, the toilet seat incorporates carbon fiber. Since carbon fiber has an electrothermal conversion efficiency of up to 95-99%, the toilet seat made of carbon fiber heating wire can more efficiently convert electrical energy into thermal energy than alloy resistance wire, and the toilet seat can reach a comfortable temperature in a shorter time. In addition, the heating wire emits far-infrared rays with a wavelength of 3-16 μm. Far-infrared rays have a health-promoting effect on the human body. After the human body absorbs the far-infrared rays, it can effectively promote blood circulation and metabolism, enhance the body's immunity and the tissue regeneration ability of biological cells, thus making the heating seat have the functions of human heating and health care. It can be seen that the toilet seat has higher heating performance and practicality.

[0057] In some embodiments of the present application, the core body mentioned in the aforementioned embodiments is further introduced. In addition to the carbon fiber filaments mentioned in the aforementioned embodiments, the core body can also include multiple alloy resistance wires to allow the carbon fiber filaments and the alloy resistance wires to generate mixed heat.

[0058] The material types included in each alloy resistance wire may include but are not limited to a combination of one or more of copper, nickel, chromium, aluminum and iron, and the wire diameter of each alloy resistance wire may be 0.02 to 0.50 mm.

[0059] Furthermore, each alloy resistance wire can be arranged in parallel with the carbon fiber wire in the core, or each alloy resistance wire can be arranged spirally wrapped with the carbon fiber wire in the core, or some of the alloy resistance wires can be arranged spirally wrapped with the carbon fiber wire in the core, and the remaining alloy resistance wires can be arranged in parallel.

[0060] It can be understood that when each alloy resistance wire is arranged in parallel with the carbon fiber wire in the core, the structural stability of the core in the axial direction of the fiber and the resistance to tension and pressure are enhanced on the basis of the parallel arrangement of each carbon fiber wire. When each alloy resistance wire is spirally wound and arranged with the carbon fiber wire in the core, the toughness, stability and reliability of the overall structure of the core can be further improved on the basis of the spiral winding arrangement of each carbon fiber wire. When some of the alloy resistance wires in each alloy resistance wire are spirally wound and arranged with the carbon fiber wire in the core, and the remaining alloy resistance wires are arranged in parallel, the structural stability of the core in the axial direction of the fiber and the resistance to tension and pressure, as well as the toughness, stability and reliability of the overall structure of the core can be simultaneously enhanced.

[0061] Considering that the heating of the toilet seat requires electrical energy, in some embodiments of the present application, both ends of the core mentioned in the aforementioned embodiments can be connected with non-heating leads, which have a conductive function and are used to connect to the power supply equipped with the smart toilet.

[0062] Alternatively, a non-heating wire segment made of copper or aluminum wire can be embedded in the core to connect to the power supply of the smart toilet. The copper or aluminum wire can have a diameter of 0.02 to 0.80 mm, specifically matching the diameter of the heating wire.

[0063] It can be understood that when the heating wire is powered on and generates heat, since the lead wire or non-heating wire end does not generate heat, the process of converting electrical energy into thermal energy is concentrated in the core of the heating wire, thereby achieving more efficient electrical-thermal energy conversion.

[0064] In order to improve the user experience of the toilet seat, in some embodiments of the present application, the toilet seat mentioned in the aforementioned embodiment is further introduced. The toilet seat may include a temperature regulator, which can control the working temperature of the heating wire after power is turned on, so that the user can obtain a more comfortable and safe use experience.

[0065] Finally, it should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0066] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The various embodiments can be combined as needed, and the same or similar parts can be referenced to each other.
