Description

Technical Field

[0001] This utility model relates to the field of seat ring technology, and in particular to a heated seat ring. Background Technology

[0002] Urea-formaldehyde resin has high hardness, resulting in good scratch resistance. Furthermore, the molded urea-formaldehyde resin exhibits a strong ceramic-like texture and good resistance to yellowing, making it a common choice for toilet seat rings. However, when using urea-formaldehyde resin in heated toilet seat rings, the following problems arise:

[0003] Urea-formaldehyde is a thermosetting material that requires compression molding. When the heating module's lead wire is led out from the seat ring, it is squeezed by the upper and lower molds, which may cause it to break or be crushed. This would prevent the heating module from making an electrical connection with the seat ring base, causing the seat ring heating function to fail and increasing production costs.

[0017] 1. This utility model proposes a heated seat ring, comprising a seat ring body and a heating module disposed within the seat ring body. The seat ring body has an embedded part with a cavity and an inlet and an outlet connecting the cavity. The lead wire of the heating module passes through the inlet and is then housed within the cavity, preventing damage to the lead wire from the upper and lower molds during the seat ring molding process.

Detailed Implementation

[0037] The following is combined with Figures 1-11 This utility model will be described in detail.

[0038] A heated seat ring includes a seat ring body 10, within which a heating module 30 is disposed. The seat ring body 10 has an embedded part 40, which has a cavity 401 and an inlet 402 and an outlet 403 connecting the cavity 401. The lead wire 303 of the heating module 30 passes through the inlet 402 and is housed within the cavity 401, preventing damage to the lead wire 303 from the upper and lower molds during the seat ring molding process. After molding is completed, the lead wire 303 is pulled out from the outlet 403 for easy connection to the base, thereby supplying power to the heating module 30.

[0039] In this embodiment, a first support 201 is provided on one side of the rear end of the seat ring body 10, and a second support 202 is provided on the other side of the rear end of the seat ring body 10. One of the first support 201 and the second support 202 is provided with an embedded part 40. Further, the embedded part 40 is located on the first support 201, and the end face of the embedded part 40 facing the second support 202 is flush with the end face of the first support 201 facing the second support 202. The distance L between the end face of the embedded part 40 away from the second support 202 and the end face of the first support 201 away from the second support 202 is at least 2.5 mm. Figure 7 As shown, this ensures the thickness of the urea-formaldehyde coating on the surface of the embedded part 40, thus improving the phenomenon that urea-formaldehyde material is prone to falling off around the end face of the embedded metal part.

[0040] In this embodiment, as Figure 5As shown, the first support 201 is also provided with a first hinge hole 502, which is connected to the cavity 401 via an outlet 403. The lead wire 303 is pulled out after passing through the outlet 403 and the first hinge hole 502 in sequence. Furthermore, one end of the embedded part 40 facing the second support 202 is provided with an opening 4031 connected to the cavity 401. The side wall of the embedded part 40 near the opening 4031 is provided with a notch 4032 connected to the opening 4031. The purpose of providing the notch 4032 is to prevent the pulled-out wire from interfering with the connection between the seat ring base and the rotating shaft. The notch 4032 and the opening 4031 together constitute the outlet 403. Meanwhile, the end face of the first support 201 facing the second support 202 is provided with a groove 501. The groove 501 connects the first hinge hole 502 and the outlet 403. Specifically, the first hinge hole 502 is connected to the notch 4032 via the groove 501, and then to the cavity 401, so that the pulled-out lead wire 303 can be placed in the groove 501. After the molding is completed, the lead wire 303 is pulled out from the opening 4031. After being pulled out, the lead wire 303 passes through the notch 4032 and the groove 501 in sequence, and is finally pulled out from the first hinge hole 502 for electrical connection to the seat ring base.

[0041] In this embodiment, as Figure 8 As shown, the outer surface of the embedded part 40 has a protrusion 404, which allows urea-formaldehyde to wrap around the protrusion 404 during molding, improving the bonding force between the embedded part 40 and the urea-formaldehyde material. Alternatively, a recess can be provided at a certain position on the outer surface of the embedded part 40, allowing the urea-formaldehyde material to flow into the recess during molding. The protrusion 404 and the recess work together to further improve the bonding force between the embedded part 40 and the urea-formaldehyde material. Simultaneously, the embedded part 40 is fixed in a preset position to prevent displacement of the embedded part 40 during molding, which would affect the molding effect. A sealing material, such as epoxy resin or glue, is filled between the lead wire 303 and the inlet 402 to prevent urea-formaldehyde material from entering the interior of the embedded part 40 during molding, thus preventing the lead wire 303 from being pulled out. Furthermore, the embedded part 40 is made of metal, such as... Figure 10 As shown, a heat-conducting component 80 connects the embedded part 40 and the heating module 30. The heat-conducting component 80 is made of a metal with good thermal conductivity, such as copper or aluminum. In use, the heat from the heating module 30 is conducted to the embedded part 40 through the heat-conducting component 80. The embedded part 40 is also equipped with a temperature fuse to monitor its temperature. When the temperature of the embedded part 40 exceeds a preset threshold, the temperature fuse burns out, and the heating module 30 stops heating, thus providing over-temperature protection.

[0042] In this embodiment, the second support 202 is provided with a second hinge hole 602 and a material leakage hole 601, such as Figure 6As shown. The second hinge hole 602 is used to connect the lifting device and is the main stress point during the lifting process of the seat body 10. The material-stealing hole 601 is a blind hole with a depth of approximately 10mm. Its function is to prevent the first support 201 from being too thick and to solve the problem of uneven curing during the molding process.

[0043] In this embodiment, as Figure 9 As shown, heating wires 301 are provided at certain locations within the heating module 30, and perforations 302 are provided at the locations where heating wires 301 are located. Specifically, the heating module 30 uses a heating film made of PET-encapsulated graphene material. The heating wires 301 are arranged in an S-shape within the heating film. Therefore, perforations 302 can be provided at locations where heating wires 301 are not located, facilitating the flow of urea-formaldehyde material during molding and improving the bonding force between the heating film and the urea-formaldehyde material. Furthermore, a thermally conductive layer is provided on the surface of the heating module 30. This thermally conductive layer is applied to the surface of the heating module 30 by adhesive bonding or spraying, preventing the heat generation area from concentrating around the heating wires 301, thereby increasing the heat generation area.

[0044] During the compression molding process, if the heating module 30 is directly molded together with urea-formaldehyde, delamination can easily occur between the heating module 30 and the urea-formaldehyde material, leading to a decrease in thermal conductivity and physical properties. Therefore, if... Figure 11 As shown, a compatibility layer 70 is provided on the surface of the heating module 30 to improve the adhesion between the heating module 30 and the urea-formaldehyde material and reduce the occurrence of delamination between the heating module 30 and the urea-formaldehyde material.

[0045] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
