Description

Technical Field

[0001] The utility model relates to the technical field of bathroom appliances, in particular to a fixing structure of a heating wire of a toilet seat. Background Art

[0002] As people's living standards improve, the requirements for comfort and functionality of household items are getting higher and higher. Among bathroom equipment, smart toilets are favored by consumers because of the many convenient functions they provide, among which the heating function of the toilet seat is especially popular among users in cold regions.

[0003] In the existing technology, urea-formaldehyde heated toilet seats are mainly formed in two ways:

[0004] One method is to cover the surface of the cover plate with a carbon film as a heating element by brushing after the cover plate is formed. Although this method can achieve the heating function, the carbon film is not tightly bonded to the cover plate, and it is easy to fall off or be damaged after long-term use, affecting the heating effect and the service life of the cover plate.

[0005] Another way is to use two pieces of cover material and add adhesive to sandwich the heating component in the middle. Although this method can solve the problem of carbon film falling off to a certain extent, the heat transfer is not uniform because the heating component is sandwiched between the two cover plates, and the use of adhesive may also affect the overall performance and environmental friendliness of the cover plate. In addition, this process is difficult, has poor strength, poor weather resistance and other disadvantages, and cannot meet the performance requirements of the seat ring. Utility Model Content

[0006] The utility model aims to provide a heating wire fixing structure for a toilet seat which can firmly fix the heating wire, ensure uniform heating and reduce costs.

[0007] To achieve the above-mentioned purpose, the solution of the utility model is: a fixing structure of a heating wire of a toilet seat, comprising an upper cover, a lower cover and a heating assembly;

[0008] The heating assembly comprises a fixing frame and a heating wire, wherein the fixing frame is provided with a wire groove, the heating wire is completely embedded in the wire groove, and a plurality of wire clamping assemblies are provided at the groove opening of the wire groove, and the wire clamping assemblies are used to limit the heating wire pressed into the wire groove from rebounding out of the wire groove;

[0009] The upper cover is formed by compression molding, the heating component is embedded between the upper cover and the lower cover, and the lower cover is secondary compression molded on the upper cover and the heating component.

[0010] Furthermore, the depth of the wire groove is greater than or equal to the diameter d of the heating wire;

[0011] The opening width W of the wire clamping assembly is less than or equal to the heating wire diameter d.

[0012] Furthermore, a plurality of groups of the wire clamping assemblies are evenly distributed on the wire slot along the track of the wire slot.

[0013] Furthermore, each set of wire clamping assemblies includes two wire clamping buckles, and the two wire clamping buckles extend toward each other from the wire slot openings, and the formed opening width W is less than the heating wire diameter d.

[0014] Furthermore, the wire grooves on the fixing frame are in a wavy or sawtooth shape, and the wire grooves are evenly distributed on the entire fixing frame.

[0015] Furthermore, the heating wires are all embedded on the same side of the fixing frame.

[0016] Furthermore, the upper cover is provided with a groove, the fixing frame is placed in the groove and one side of the fixing frame wire groove notch is closely fitted with the bottom surface of the upper cover groove, so that the heating wire is in direct contact with the upper cover surface.

[0017] Furthermore, a card block is provided at the front end of the fixing frame, a card slot is provided at the front end of the upper cover at a position corresponding to the card block, a positioning slot is provided at the rear end of the fixing frame, and a positioning protrusion is provided at the rear end of the upper cover at a position corresponding to the positioning slot. When the fixing frame is placed on the upper cover, the positioning slot on the fixing frame is aligned with the positioning protrusion on the upper cover to achieve positioning, and the card block on the fixing frame is embedded in the card slot on the upper cover to achieve stable installation of the fixing frame and the upper cover.

[0018] Furthermore, the upper cover and the lower cover are both formed by molding thermosetting materials.

[0019] Furthermore, a flow channel is formed on the fixing frame, and the material for forming the lower cover flows between the flow channel and the upper cover.

[0020] After adopting the above scheme, the beneficial effects of the utility model are:

[0021] 1. Convenient and firm molding: The utility model adopts a secondary molding process, first molding the upper cover, then placing the heating wire fixing frame together with the heating wire on the upper cover, and then molding the lower cover for the second time on this basis, completing the combined molding of the three at the same time. Not only is molding convenient, but it can also effectively avoid the errors and inconveniences caused by multiple assemblies, and improve the integrity and stability of the product.

[0022] 2. The heating wire is firmly fixed and heated evenly: The design of the wire slot and the wire clamp assembly ensures that the heating wire is completely embedded in the wire slot, and the wire clamp assembly is used to limit the rebound of the heating wire, so that the heating wire is firmly fixed in the wire slot. This embedding method can prevent the heating wire from being crushed, squeezed or messed during molding, and avoid non-heating or uneven heating;

[0023] Compared with the three-point positioning method used in the prior art, the track-type full-length positioning winding method of the utility model enables a longer heating wire to fit in the wire slot throughout the entire length, which not only improves the positioning accuracy, but also enhances the stability of fixation.

[0024] 3. Improve thermal conductivity: During assembly, place one side of the fixed wire trough slot close to the inner surface of the upper cover so that the heating wire can directly contact the inner surface of the seat ring, thereby improving thermal conductivity.

[0025] 4. Reduce product costs: Since the utility model fully protects the heating wire and is not easy to break, the heating wire can use a thinner wire diameter and the seat ring thickness can be correspondingly thinned, which is conducive to forming a denser product. The seat ring thickness is thinned, the material consumption is reduced, and the product cost can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] The utility model provides a fixing structure of a heating wire of a toilet seat, such as Figures 1 to 8 As shown, it includes an upper cover 1, a lower cover 2 and a heating assembly. The upper cover 1 is made by a compression molding process, and the heating assembly is embedded between the upper cover 1 and the lower cover 2. In order to increase the stability and sealing of the structure, the lower cover 2 is formed by a secondary compression molding technology based on the upper cover 1 and the heating assembly.

[0042] like Figure 1 and Figures 5 to 8 As shown, the heating assembly includes a fixing frame 3 and a heating wire 4. The fixing frame 3 is provided with a wire groove 31. The depth of the wire groove 31 is greater than or equal to the diameter d of the heating wire 4, so as to ensure that when the heating wire 4 is pressed into the wire groove 31 according to the preset groove track, the heating wire 4 can be completely embedded in the wire groove 31 and will not be higher than the plane of the fixing frame 3. Such a design can effectively prevent the heating wire 4 from being pressed, squeezed or jumbled during the molding process, thereby ensuring the stability and uniformity of the toilet seat heating function.

[0043] like Figure 1 and Figure 4 As shown, the upper cover 1 is provided with a groove 11 for placing the fixing frame 3, and the fixing frame 3 is placed in the groove 11 and covers the entire upper cover 1. The shape of the wire groove 31 is preset according to the shape that the heating wire 4 needs to be shaped, and is mostly wavy or zigzag. It allows the heating wire 4 to be accurately embedded in the wire groove 31 along a predetermined track. The wire grooves 31 are evenly distributed on the entire fixing frame 3, and the track of the wire groove 31 covers the entire plane of the fixing frame 3 as much as possible. When installed in the toilet seat, the entire toilet seat is heated evenly. In addition, the heating wire 4 is often faced with inaccurate positioning and loose fixing during installation and use due to its long length and often appearing disordered. However, in this solution, the design of the wire groove 31 effectively solves these problems. Compared with the three-point positioning method commonly used in the prior art, this track-type full-range positioning winding method has significant advantages. Although the three-point positioning can fix the heating wire 4 to a certain extent, due to its limited positioning points, it is easy to shift or deform during molding, resulting in uneven heating effect. The track-type full-length positioning winding method uses a continuous track design to enable the heating wire 4 to fit in the wire slot 31 throughout the entire process, which not only improves the positioning accuracy, but also enhances the fixing stability.

[0044] As a further improvement of the structure, a plurality of wire clamping components 5 are provided at the slot of the wire slot 31. Figures 6 to 8 As shown, the width of these wire clamping components 5 is smaller than the diameter d of the heating wire 4. Their function is to limit the heating wire 4 from rebounding out of the wire groove 31 after the heating wire 4 is pressed into the wire groove 31, so as to ensure that the heating wire 4 is firmly fixed in the wire groove 31. Even in the secondary molding process, it can maintain its stable position, further improving the reliability and durability of the toilet seat heating function. In addition, in order to further enhance the stability and safety of the heating wire 4 in the wire groove 31, several groups of wire clamping components 5 are evenly distributed on the wire groove 31 and arranged along the track of the wire groove 31. Figure 5 As shown, the wavy wire groove 31 is evenly and evenly provided with wire clamping assemblies 5. These wire clamping assemblies 5 evenly limit the heating wire 4 in the wire groove 31, ensuring that the heating wire 4 will not move or pop out of the wire groove 31 at will when subjected to external force or vibration. In this embodiment, each set of wire clamping assemblies 5 includes two wire clamping buckles 51, which extend toward each other from the notch of the wire groove 31, and the opening width W formed is less than the diameter d of the heating wire 4. Therefore, when the heating wire 4 is pressed into the wire groove 31, the heating wire 4 will not pop out from this opening, that is, it will not rebound from the wire groove 31.

[0045] like Figure 1 and Figure 5 As shown, the front end of the fixing frame 3 is provided with a block 32, the front end of the upper cover 1 is provided with a slot 12 at a position corresponding to the block 32, the rear end of the fixing frame 3 is provided with a positioning slot 33, and the rear end of the upper cover 1 is provided with a positioning protrusion 13 at a position corresponding to the positioning slot 33. When the fixing frame 3 is placed on the upper cover 1, the positioning slot 33 on the fixing frame 3 is aligned with the positioning protrusion 13 on the upper cover 1 to achieve positioning, and the block 32 on the fixing frame 3 is embedded in the slot 12 on the upper cover 1, thereby achieving stable installation of the fixing frame 3 and the upper cover 1.

[0046] like Figure 5 and Figure 6 As shown, the fixing frame 3 is formed with flow channels 34, and the function of these flow channels 34 is to allow the material for forming the lower cover 2 to flow between the flow channels 34 and the upper cover 1 during the molding process. This ensures that the material can evenly cover the contact surface between the fixing frame 3 and the upper cover 1, thereby achieving a firm combination between the fixing frame 3 and the lower cover 2. At the same time, the reasonable design of the flow channels 34 can also improve production efficiency, reduce the scrap rate, and improve product quality.

[0047] In this embodiment, the heating wires 4 are located on the same side of the fixing frame 3. By placing the heating wires 4 on the same side of the fixing frame 3, confusion or misalignment of the heating wires 4 during installation can be effectively avoided, thereby ensuring uniformity and stability of the heating effect.

[0048] The upper cover 1 and the lower cover 2 are both made of thermosetting materials with good heat resistance and chemical corrosion resistance through a molding process. The selection of this material ensures the stability and durability of the toilet seat heating wire 4 fixing structure in complex environments such as high temperature and humidity, further improving the overall performance and service life of the product.

[0049] The molding process of the fixing structure of the heating wire of the toilet seat ring of the utility model is as follows:

[0050] S1, assembling the heating assembly: pressing the heating wire 4 into the wire groove 31 of the fixing frame 3 according to the track of the wire groove 31, and the wire buckle 51 firmly fixes the heating wire 4 in the wire groove 31;

[0051] S2, first mold the upper cover 1, then open the mold, put in the assembled heating wire 4 assembly (including the fixing frame 3 and the heating wire 4 embedded thereon), so that one side of the notch of the wire groove 31 of the fixing frame 3 is close to the bottom surface of the groove 11 of the upper cover 1, even if the heating wire 4 directly contacts the surface of the upper cover 1, the heat conduction efficiency is improved;

[0052] S3, adding thermosetting materials such as plastic rice into the mold cavity, and secondary molding the lower cover 2 on the basis of the upper cover 1 and the heating component, and finally opening the mold to take out the product, so as to obtain a combination of the upper cover 1, the heating component and the lower cover 2.

[0053] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which 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 contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention.
