Description
Technical Field
[0001] This utility model relates to the field of toilet heated seat technology, specifically a toilet heated seat fixed with aluminum foil without adhesive coating. Background Technology
[0002] In the existing technology, toilet heating is mainly achieved through electric auxiliary heating. The heating component of the toilet is encapsulated in the middle pad of the toilet. The heating component mainly includes aluminum foil as a heat carrier and heating cable as a heat source. The heating cable is bonded to the aluminum foil, and the side of the aluminum foil away from the heating cable is attached to the middle pad. The heat generated by the heating cable is transferred through the aluminum foil to the middle pad that is in direct contact with the human body during use, so as to improve the user experience.
[0003] Existing toilet seat heating systems use adhesive to fix aluminum foil, a complex and costly process. The presence of adhesive is also environmentally unfriendly, and with prolonged use, the adhesive can age and delaminate, causing the aluminum foil to detach. Furthermore, when fixing the heated seat to the existing toilet seat, the fixing method sometimes results in incompatibility between different toilet seats. Therefore, we propose a toilet seat heating system that eliminates the need for adhesive-coated aluminum foil fixing. Utility Model Content
[0004] The purpose of this utility model is to provide a toilet heated seat ring that is fixed with aluminum foil without adhesive coating. This toilet heated seat ring that is fixed with aluminum foil without adhesive coating solves the problem that the aluminum foil will fall off after long-term use due to the aging and delamination of the adhesive layer in the existing toilet heated seat rings that are glued together.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A toilet seat with a heated seat fixed by aluminum foil without adhesive coating includes an aluminum foil base and a top cover. The top surface of the aluminum foil base is fixedly connected to the bottom surface of the top cover. A heating cable is provided on the inner side of the aluminum foil base. An electrical connector is fixedly connected to one end of the heating cable. A power supply line is fixedly connected to the end of the electrical connector away from the heating cable. The device also includes a fixing component for connecting the aluminum foil base to the toilet seat without adhesive coating, avoiding glue adhesion and preventing the aluminum foil from falling off due to glue aging and delamination after prolonged use. The fixing component includes a movable groove located on the inner side of the aluminum foil base. A linkage block is slidably connected to the inner side of the movable groove. U-shaped blocks are fixedly connected to both ends of the linkage block. A hinge plate one is fixedly connected to the surface of the U-shaped block away from the linkage block. A shaft is rotatably connected through the inner side of the hinge plate one. A second hinge plate two is fixedly connected through the shaft. A clamping block is fixedly connected to the surface of the second hinge plate two.
[0007] Preferably, a rubber anti-slip block is fixedly connected to the side of the clamping block near the U-shaped block, and a torsion spring is fixedly connected to the surface of the second hinge plate, with the end of the torsion spring away from the second hinge plate being fixedly connected to the surface of the U-shaped block.
[0008] Preferably, an abutment block is fixedly connected to the side surface of the clamping block near the U-shaped block, and the side of the abutment block near the U-shaped block is an arc-shaped surface.
[0009] Preferably, a push rod is slidably connected to the inner side of the linkage block, and the push rod passes through the U-shaped block and is slidably connected to the U-shaped block.
[0010] Preferably, the push rod is fixedly connected to a ramp block at one end near the contact block, and the end of the ramp block facing the arc surface of the contact block is a ramp.
[0011] Preferably, a sleeve is fixedly connected to the inner side of the linkage block, the push rod is inserted into the sleeve, and an anti-detachment plate is fixedly connected to one end of the push rod located inside the sleeve.
[0012] Preferably, there are two sets of anti-detachment plates, and the two sets of anti-detachment plates are symmetrically arranged with the center line of the sleeve as the axis of symmetry, and a spring is fixedly connected between the two sets of anti-detachment plates.
[0013] By employing the above technical solution, this utility model provides a toilet heated seat ring that is fixed with aluminum foil without the need for adhesive coating. It has at least the following beneficial effects:
[0014] 1. This utility model uses symmetrically arranged push rods to push symmetrically arranged anti-detachment plates, which compresses the spring inside the sleeve. Then, the aluminum foil base is aligned with the toilet seat. After releasing the clamping block, the compressed torsion spring will spring back to the hinge plate and rotate the clamping block to reset. At the same time, the compressed spring will also push the push rod to reset through the anti-detachment plate, so that the push rod pushes the inclined block to lift the abutment block. Through the abutment force of the spring and torsion spring, the clamping block drives the rubber anti-slip block to stick tightly to the side of the toilet seat, making the entire aluminum foil base more stable during installation.
[0015] 2. This utility model uses springs and torsion springs to drive the clamping block to rotate and clamp the toilet seat, eliminating the need for adhesive bonding of the aluminum foil base during installation. This avoids the aluminum foil base from falling off due to aging and delamination of the adhesive after long-term use. At the same time, the linkage block can slide back and forth in the movable groove, allowing the clamping block to be adapted to more models of toilet seats for installation, thus expanding its applicability and extending its service life.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] A toilet seat heating element that requires no adhesive and is fixed with aluminum foil, such as Figure 1 - Figure 6As shown, the device includes an aluminum foil base 1 and a top cover 3. The top surface of the aluminum foil base 1 is fixedly connected to the bottom surface of the top cover 3. A heating cable 4 is provided inside the aluminum foil base 1, and an electrical connector 5 is fixedly connected to the end of the heating cable 4. A power supply line 6 is fixedly connected to the end of the electrical connector 5 away from the heating cable 4. The device also includes a fixing component 2, which allows the aluminum foil base 1 to be connected to the toilet seat without applying adhesive, avoiding glue adhesion and preventing the aluminum foil from falling off due to glue aging and delamination after long-term use. The fixing component 2 includes a movable groove 21, which is opened inside the aluminum foil base 1. A linkage block 22 is slidably connected to the inner side of the movable groove 21, and both ends of the linkage block 22 are fixedly connected to U. A hinge plate 24 is fixedly connected to the side of U-shaped block 23 away from linkage block 22. A shaft 25 is rotatably connected through the inner side of hinge plate 24. A second hinge plate 26 is fixedly connected through the shaft 25. A clamping block 28 is fixedly connected to the surface of hinge plate 26. When clamping block 28 is moved, it drives shaft 25 to rotate around shaft 25 via hinge plate 26. Simultaneously, the rotation of clamping block 28 causes rubber anti-slip block 29 to rise, and hinge plate 26 compresses torsion spring 27. After clamping block 28 is released, the compressed torsion spring 27 springs back to hinge plate 26, returning clamping block 28 to its original position. A rubber anti-slip block 29 is fixedly connected to the side of clamping block 28 near U-shaped block 23. A torsion spring 27 is fixedly connected to the surface of hinge plate 26, with the end of torsion spring 27 away from hinge plate 26 fixedly connected to the surface of U-shaped block 23. A contact block 210 is fixedly connected to the side surface of the clamping block 28 near the U-shaped block 23. The side of the contact block 210 near the U-shaped block 23 is an arc-shaped surface. A push rod 211 is slidably connected to the inner side of the linkage block 22. The push rod 211 passes through the U-shaped block 23 and is slidably connected to the U-shaped block 23. The push rod 211 is fixedly connected to the inclined block 212 near the abutment block 210. When the clamping block 28 is released, the compressed torsion spring 27 will cause the clamping block 28 to rotate and reset through the spring-back hinge plate 26. At the same time, the compressed spring 215 will also push the push rod 211 to reset through the anti-detachment plate 214, so that the push rod 211 pushes the inclined block 212 to lift the abutment block 210. Through the abutment force of the spring 215 and the torsion spring 27, the clamping block 28 drives the rubber anti-slip block 29 to stick tightly to the side of the toilet seat on the toilet, making the entire aluminum foil base 1 more stable when installed. The end of the inclined block 212 facing the arc surface of the abutment block 210 is an inclined surface. A sleeve 213 is fixedly connected to the inner side of the linkage block 22. The push rod 211 is inserted into the sleeve 213. During the rotation of the clamping block 28, it will drive the abutment block 210 fixedly connected to its surface to rotate together. When the abutment block 210 rotates, its arc surface will gradually abut the inclined surface of the inclined block 212, thereby forcing the inclined block 212 to push the push rod 211. When the push rod 211 is pushed, it will retract into the interior of the sleeve 213. The end of the push rod 211 located inside the sleeve 213 is fixedly connected to an anti-detachment plate 214.There are two sets of anti-detachment plates 214, and the two sets of anti-detachment plates 214 are symmetrically arranged with the center line of the sleeve 213 as the axis of symmetry. A spring 215 is fixedly connected between the two sets of anti-detachment plates 214. The push rod 211 will push the anti-detachment plates 214. By pushing the symmetrically arranged anti-detachment plates 214 with the push rod 211, the spring 215 in the sleeve 213 can be compressed.
[0026] In the use of this utility model, a toilet heated seat ring fixed with adhesive-free aluminum foil is installed by first moving the clamping block 28. After the clamping block 28 is moved, it drives the shaft 25 to rotate around the shaft 25 via the hinge plate 26. At the same time, the rotation of the clamping block 28 causes the rubber anti-slip block 29 to rise, and the hinge plate 26 compresses the torsion spring 27. After the clamping block 28 is released, the compressed torsion spring 27 will spring back to the hinge plate 26, causing the clamping block 28 to return to its original position. During the rotation of the clamping block 28, it will also cause the abutment block 210 fixed to its surface to rotate. When the abutment block 210 rotates, its arc-shaped surface will gradually abut against the inclined surface of the inclined block 212, thereby forcing the inclined block 212 to push the push rod 211. When the push rod 211 is pushed... The sleeve 213 will then retract into its interior, and the push rod 211 will push the anti-detachment plate 214. By pushing the symmetrically arranged anti-detachment plate 214 through the push rod 211, the spring 215 inside the sleeve 213 can be compressed, and then the aluminum foil base 1 will be aligned with the toilet seat. Then the clamp 28 will be released, and the compressed torsion spring 27 will drive the clamp 28 to rotate and reset through the spring-back hinge plate 26. At the same time, the compressed spring 215 will also push the push rod 211 to reset through the anti-detachment plate 214, so that the push rod 211 pushes the inclined block 212 to lift the abutment block 210. Through the abutment force of the spring 215 and the torsion spring 27, the clamp 28 will drive the rubber anti-slip block 29 to stick tightly to the side of the toilet seat, making the entire aluminum foil base 1 more stable during installation.
[0027] Furthermore, the clamping block 28 is driven to rotate and clamp the toilet seat by the spring 215 and the torsion spring 27, eliminating the need for adhesive bonding of the aluminum foil base 1 during installation. This prevents the aluminum foil base 1 from falling off due to aging and delamination of the adhesive after long-term use. At the same time, the linkage block 22 can slide back and forth in the movable groove 21, allowing the clamping block 28 to be adapted to more models of toilet seats for installation, thus having a wider range of applications and a longer service life.
