Description

Technical Field

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

[0002] Common toilet seats on the market typically use a combination of upper and lower covers. Because these seats often integrate critical electronic components (such as heating elements and temperature sensors), or to meet the required mechanical strength and structural stability, adhesive (usually hot melt adhesive or epoxy resin) is often injected into the interior during assembly. The specific steps are: invert the upper cover, inject adhesive into the upper cover, and then fasten the upper and lower covers together.

[0003] However, because the inner surface of the toilet seat cover is usually not a regular flat structure, in order to conform to ergonomics and product shape, when the cover is inverted, its inner shape often presents a concave shape with a relatively higher central area and a significantly lower area near the front and rear ends. This special geometry causes a problem during the static curing stage after glue application: under the influence of gravity, the fluid liquid glue naturally accumulates towards the lowest point of the toilet seat cover. This glue migration phenomenon leads to a critical quality defect—the glue layer thickness in the lower area of ​​the seat is significantly increased (too thick glue), while the glue layer in the central area, which requires more support and fixation (such as the core parts for installing electronic components or structural locations requiring reinforced support, usually the central area of ​​the seat), becomes thinner or even insufficient. This can ultimately affect the fixation and protection of electronic components and may even weaken the overall structural strength and durability of the toilet seat. This situation, where the amount of glue applied to different parts of the toilet seat cannot be controlled according to actual production needs, resulting in glue layer distribution that does not achieve the expected effect, is a key problem that needs to be addressed during the production process. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a seat ring rubber-blocking structure.

[0005] This utility model is achieved by the following method: a seat ring adhesive-blocking structure, including an upper cover and a lower cover, the upper cover and the lower cover are spliced ​​together to form an inner cavity, the upper cover and / or the lower cover are provided with adhesive-blocking posts, when the upper cover and the lower cover are spliced ​​together, the adhesive-blocking posts divide the inner cavity into at least an independent first region and a second region at a preset position, the first region and / or the second region are filled with adhesive.

[0006] Preferably, the adhesive-blocking post is made of a deformable material.

[0007] Preferably, the deformable material is tin foil, silicone, or rubber.

[0008] Preferably, the longitudinal cross-sectional dimension of the glue-blocking post in its initial state is greater than the longitudinal cross-sectional dimension of the inner cavity formed by the upper cover and the lower cover at its location after being assembled; after the upper cover and the lower cover are assembled, the longitudinal cross-sectional dimension of the glue-blocking post is equal to the longitudinal cross-sectional dimension of the inner cavity formed by the upper cover and the lower cover at its location.

[0009] Preferably, the inner cavity includes a high region and a low region, and the adhesive-blocking post can separate the high region and the low region, with the first region located in the low region and the second region located in the high region.

[0010] Preferably, the high-position area is located in the middle or lower part of both sides of the inner cavity.

[0011] Preferably, a heating wire is provided in the upper cover or the lower cover, and the adhesive-blocking post is provided on the heating wire, with the bottom of the adhesive-blocking post sealingly fitted to the heating wire.

[0012] Preferably, a seating sensor is provided in the second region, and the seating sensor is wrapped with glue.

[0013] Preferably, the upper cover and the lower cover are bonded together by the adhesive in the first region and / or the second region.

[0014] Preferably, the upper cover and the lower cover are further provided with connecting holes, and a connector is inserted through the connecting holes to connect and fix the upper cover and the lower cover.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a seat ring adhesive-blocking structure, which, compared with the prior art, has at least the following technical effects: 1. The adhesive-blocking column divides the inner cavity into at least an independent first region and a second region at a preset position. The first region and / or the second region is filled with adhesive. The user can set an area that can be independently injected with adhesive according to actual needs. The independent region restricts the adhesive to the predetermined area. As a physical barrier, the adhesive-blocking column can also be adjusted more flexibly according to actual needs when injecting adhesive. 2. The deformable material (such as a soft polymer) can adapt to the shape of the inner surface of the seat ring's upper or lower cover, ensuring that the adhesive-blocking column is tightly attached to the inner surface of the upper or lower cover, forming an effective seal and preventing adhesive leakage or migration. 3. The glue-blocking post, whose initial size is larger than the installation space, is compressed and deformed when the upper and lower covers are fastened together, forming a tight interference fit. It fits tightly with the upper or lower cover, ensuring complete sealing of the area used for glue injection and effectively preventing glue from flowing to other areas. The size of the compressed glue-blocking post matches its glue injection area, providing additional support and strengthening the mechanical strength of the seat ring in that area. 4. The adhesive-blocking pillars physically separate the high and low areas, allowing the high area to have an independently injectable adhesive zone. When injecting adhesive in the high area, it ensures that the adhesive only fills that area, preventing migration to the low area. This avoids the uneven adhesive distribution caused by the concave shape of the inner side of the top cover in existing technologies, where the shape is designed to conform to ergonomics and product design, resulting in a relatively high central area and a significantly lower area near the front and rear ends. This ensures that the liquid adhesive naturally flows towards the low area of ​​the seat ring during curing, ensuring sufficient adhesive thickness for the mounting points of electronic components in the high area. This improves the fixation and protection of electronic components or guarantees the required adhesive thickness in the necessary areas, enhancing the mechanical strength of that area and preventing excessive adhesive buildup in the low area. 5. The middle of both sides of the seat ring is a concentration area of ​​ergonomic and structural stress (such as electronic component mounting points). Providing independently injectable adhesive zones in these areas significantly improves the adhesive thickness and structural stability, enhancing the overall rigidity and durability of the seat ring. 6. The adhesive-blocking post holds the heating wire in place, securing and protecting it to prevent displacement or damage during adhesive flow and seat ring use. 7. The second area houses the seat sensor, which is encased in adhesive. By strategically designing the adhesive application area and distribution, the sensor achieves full contact with the adhesive. The adhesive's viscosity and sealing properties enhance the sensor's fixation, improving the stability and accuracy of the detection signal and enhancing the seat ring's intelligent sensing performance.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Please see Figures 1 to 4 A seat ring adhesive-blocking structure includes an upper cover 1 and a lower cover 2, which are joined to form an inner cavity. The upper cover 1 and / or the lower cover 2 are provided with adhesive-blocking posts 4. When the upper cover 1 and the lower cover 2 are joined, the adhesive-blocking posts 4 divide the inner cavity into at least a first region 3 and a second region 7 at a preset position. The first region 3 and / or the second region 7 are filled with adhesive. Users can set independently injectable areas according to their actual needs. These independent injection areas confine the adhesive within the predetermined areas. The adhesive-blocking posts 4 act as physical barriers, allowing for more flexible adjustment of the amount of adhesive injected into different areas based on actual needs. In this embodiment, four adhesive-blocking posts are provided, dividing the inner cavity of the seat ring into at least a first region 3, a second region 7, a third region 8, and a fourth region 9 at preset positions. Adhesive is injected into each of the four regions separately according to actual injection requirements. The second region 7 and the third region 8 are symmetrically arranged in the middle area on the left and right sides of the inner cavity. The first region 3 is located in the rear or front part of the inner cavity, and the fourth region 9 is located in the front or rear part of the inner cavity. In the preferred embodiment, the first region 3 is located in the front part, and the fourth region 9 is located in the rear part.

[0024] Please see Figures 1 to 4 Preferably, in this embodiment, the adhesive-blocking post 4 is initially fixed to the upper cover 1.

[0025] Please see Figures 1 to 4 Preferably, the adhesive-blocking post 4 is made of a deformable material. The deformable material (such as a soft polymer) adheres tightly to the inner surface of the upper cover 1 or lower cover 2 during the fastening process of the upper and lower covers 2, ensuring that the adhesive-blocking post 4 adheres tightly to the inner surface of the upper cover 1 or lower cover 2, forming an effective seal and preventing adhesive leakage or migration.

[0026] Please see Figures 1 to 4 Preferably, the deformable material is tin foil, silicone, or rubber. It can also be TPE, EPDM, etc., and is not limited to these, as long as it can deform under pressure and completely fit the inner surfaces of the upper cover 1 and the lower cover 2, so that the glue-blocking column 4 can be interference-fitted with the upper cover 1 and the lower cover 2 to prevent the glue from flowing to other areas.

[0027] Please see Figures 1 to 4 Preferably, the initial longitudinal cross-sectional dimension of the glue-blocking post 4 is larger than the longitudinal cross-sectional dimension of the inner cavity formed by the upper cover 1 and the lower cover 2 at its location; after the upper cover 1 and the lower cover 2 are connected and assembled, the longitudinal cross-sectional dimension of the glue-blocking post 4 is equal to the longitudinal cross-sectional dimension of the inner cavity formed by the upper cover 1 and the lower cover 2 at its location. The glue-blocking post 4, whose initial dimension is larger than the inner cavity, is compressed and deformed when the upper and lower covers 2 are fastened, forming a tight interference fit, ensuring that both ends of the glue injection area are completely sealed, effectively preventing glue from flowing to other areas; the dimension of the compressed glue-blocking post 4 matches the inner cavity where its glue injection area is located, providing additional support and strengthening the mechanical strength of this area.

[0028] Please see Figures 1 to 4 Preferably, the inner cavity includes a high region 10 and a low region 5, with the first region 3 located in the low region 5 and the second region 7 located in the high region 10. The adhesive-blocking column 4 can separate the high region 10 and the low region 5, allowing the high region 10 to have an area for independent adhesive injection. When injecting adhesive into the high region 10, it can ensure that the adhesive only fills the high region 10, preventing migration to the low region. This avoids the problem of uneven adhesive distribution caused by the inner shape of the toilet seat being relatively high in the middle and significantly lower near the front and rear ends, which is common in the prior art for ergonomic and product design. This ensures that the installation parts of electronic components, etc., installed in the high region receive sufficient adhesive thickness, thereby improving the fixation, heat dissipation, and protection of electronic components or ensuring the required adhesive thickness in the required parts, improving the mechanical strength of the area, and also avoiding the problem of excessive adhesive thickness caused by adhesive accumulation at both ends.

[0029] Please see Figures 1 to 4 Preferably, the high-position area 10 is located in the middle or lower middle part of both sides of the inner cavity. The middle part of both sides of the seat ring is a concentrated area of ​​ergonomic and structural stress (e.g., setting an area where electronic component mounting points can be independently glued can significantly improve the glue layer thickness and structural stability in this area, enhancing the overall rigidity and durability of the seat ring). In this embodiment, the second area 7 and the third area 8 are respectively located in the high-position area 10; the front and rear parts of the inner cavity each have a low-position area 5, and the first area 3 and the fourth area 9 are respectively located in the low-position area (see...). Figure 1 ).

[0030] Please see Figures 1 to 4 Preferably, a heating wire is provided in the upper cover 1 or the lower cover 2, and the adhesive-blocking post 4 is disposed on the heating wire, with the bottom of the adhesive-blocking post 4 sealingly fitted to the heating wire. The adhesive-blocking post 4 abuts against the heating wire, which can fix and protect the heating wire, preventing the heating wire from shifting or being damaged during glue flow and use of the seat ring. In this embodiment, the heating wire is disposed in the upper cover 1.

[0031] Please see Figures 1 to 4 Preferably, a seat sensor is provided in the second region 7, and the seat sensor is wrapped with adhesive. By properly setting the second region 7 and distributing the adhesive, the seat sensor and adhesive are in full contact. The adhesive's stickiness and sealing properties enhance the seat sensor's fixation, improve the stability and accuracy of the detection signal, and enhance the seat ring's intelligent sensing performance. Alternatively, the seat sensor can be located in a symmetrical third region 8, which is filled with adhesive.

[0032] Please see Figures 1 to 4 Preferably, the upper cover 1 and the lower cover 2 are bonded together with adhesive in the high position area 10 and / or the low position area 5. The adhesive bonding of the upper cover 1 and the lower cover 2 eliminates the need for additional complex connectors, simplifying the seat assembly process and reducing production costs. Furthermore, the combination of adhesive bonding and a rationally designed injection area enhances the connection strength between the upper cover 1 and the lower cover 2, ensuring the overall structural stability and durability of the seat.

[0033] Please see Figures 1 to 4 Preferably, the upper cover 1 and the lower cover 2 are further provided with connecting holes 6, through which a connector is inserted to connect and fix the upper cover 1 and the lower cover 2. Providing connecting holes 6 and connecting components on the upper cover 1 and the lower cover 2 offers an additional connection and fixing method, enhancing the connection strength between the upper cover 1 and the lower cover 2, ensuring the stability of the seat ring structure, and, together with adhesive bonding, improving the overall assembly quality and reliability of the seat ring. The connector can be a bolt, nut, or screw, or threaded in the connecting hole 6.

[0034] The working principle of this utility model is as follows:

[0035] Connect and assemble the upper cover 1 and the glue-blocking column 4, and fill the second area 7 and third area 8 of the high position area 10 on both sides of the upper cover 1, and the first area 3 and fourth area 9 of the low position area 5 with glue separately to wrap the electronic components (if any) such as heating wires and seating sensors. Then, fasten the upper cover 2. When the upper cover 1 and the lower cover 2 are fastened and fixed, the glue-blocking column 4, whose initial longitudinal cross-sectional dimension is larger than the longitudinal cross-sectional dimension of the inner cavity at its location, will be deformed by the pressure of the upper cover 1 and the lower cover 2. Finally, its longitudinal cross-sectional dimension is equal to the longitudinal cross-sectional dimension of the inner cavity at its location, and it tightly fills the space between the upper cover 1, the lower cover 2 and the two ends of the glue injection area to form a good seal. Wait for the glue to cure. Since the glue-blocking column 4 is set in the independent glue injection area between the upper cover 1 and the lower cover 2, the glue-blocking column 4 plays a role in preventing the glue from flowing between the areas, so that the glue is distributed according to the actual needs of the user. If the upper cover 1 and the lower cover 2 are connected and fixed through the connecting hole 6 and the connector, the connector is passed through the connecting hole 6 to further enhance the connection between the upper cover 1 and the lower cover 2.
