DETAILED DESCRIPTION

[0026] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] like Figures 1 to 4As shown, a heating film for a bathroom mirror comprises an upper aluminum foil film 1, a lower aluminum foil film 2, and a heating wire 3 coiled between the upper aluminum foil film 1 and the lower aluminum foil film 2; preferably, the heating wire 3 is a nickel-chromium heating wire. Of course, the heating wire 3 can also be a graphene heating wire or a carbon fiber heating wire. The lower aluminum foil film 2 is stamped with a winding wire groove 21 adapted to be embedded with the heating wire 3; and a plurality of glue grooves 22 are stamped and opened, each of which is connected to the winding wire groove 21. After the heating wire 3 is adapted to be embedded in the winding wire groove 21, the heating wire 3 is fixed in each of the glue grooves 22 by a first high-temperature double-sided tape 4, and the upper aluminum foil film 1 and the lower aluminum foil film 2 are connected by a second high-temperature double-sided tape 5. The core lies in the unique stamping design on the lower aluminum foil film 2. The lower aluminum foil film 2 is stamped to form a winding wire groove 21 that matches the shape of the heating wire 3. This design not only ensures the precise positioning of the heating wire 3, but also avoids the clutter in the traditional wiring method, and improves the overall aesthetics and structural stability. The glue groove 22 is used to accommodate the first high-temperature double-sided adhesive tape 4. After the heating wire 3 is embedded in the winding wire groove 21, the heating wire 3 is firmly fixed by the first high-temperature double-sided adhesive tape 4 in the glue groove 22, which effectively prevents loosening or displacement during the heating process and ensures uniform heat transfer. On the other hand, the second high-temperature double-sided adhesive tape 5 is used to connect the upper aluminum foil film 1 and the lower aluminum foil film 2 to form a double-layer stable structure. This design not only enhances the overall strength of the heating film, but also improves the durability of the structure, and can maintain stable performance even in extreme environments.

[0028] On the basis of the upper aluminum foil film 1, the lower aluminum foil film 2 and the heating wire 3, the lower aluminum foil film 2 is improved, and a coiling wire groove 21 and a glue groove 22 are opened on the lower aluminum foil film 2 by stamping. After the heating wire 3 is adapted and embedded in the coiling wire groove 21, the heating wire 3 is fixed in each glue groove 22 by a first high-temperature double-sided tape 4, and then the upper aluminum foil film 1 and the lower aluminum foil film 2 are connected by a second high-temperature double-sided tape 5. In this design, the coiling wire groove 21 is used to accurately position the heating wire 3, and then the first high-temperature double-sided tape 4 is used to firmly fix the heating wire 3 in the glue groove 22, which simplifies the installation process, reduces the installation difficulty, and makes the installation more convenient. At the same time, it effectively prevents loosening or displacement during the heating process, ensures uniform heat transfer, avoids the clutter in the traditional wiring method, and improves the overall aesthetics and structural stability of the structure.

[0029] In this embodiment, the bath mirror heating film also includes a terminal connection module 6 and a high-temperature wire 7 electrically connected to the heating wire 3; the lower aluminum foil film 2 is punched with a terminal installation groove 23 adapted to be embedded with the terminal connection module 6. In order to enhance the stability of the terminal connection module 6 on the lower aluminum foil film 2, the terminal installation groove 23 is punched on the lower aluminum foil film 2 to facilitate the precise positioning of the terminal connection module 6 and the electrical installation of the terminal connection module 6 and the heating wire 3. Among them, the terminal connection module 6 is located at the lower end of the lower aluminum foil film 2. Of course, the position of the terminal connection module 6 on the lower aluminum foil film 2 can also be reasonably set according to needs. Specifically, the terminal connection module 6 includes an electrical terminal 61, a PVC base plate 62, and a PVC cover plate 63; the two electrical terminals 61 are electrically connected to the two ends of the heating wire 3 and are installed on the PVC base plate 62; the PVC base plate 62 is adapted to be embedded in the terminal installation groove 23; the PVC cover plate 63 is adapted to cover the PVC base plate 62 and press and fix the electrical terminals 61. The terminal connection module 6 is formed by arranging the electrical terminals 61, the PVC base plate 62, and the PVC cover plate 63. The electrical terminals 61 are protected by the PVC base plate 62 and the PVC cover plate 63, which plays a good role in high temperature resistance, preventing the electrical terminals 61 from being damaged by high temperature, and facilitating stable electrical connection and installation with the heating wire 3. One end of the two high-temperature wires 7 is connected to the two electrical terminals 61 respectively; the high-temperature wire 7 is a silicone rubber insulated high-temperature wire with good electrical conductivity and high-temperature resistance.

[0030] In this embodiment, the heating wire 3 includes a straight heating segment 31, an arc heating segment 32, a first power-connected heating segment 33 and a second power-connected heating segment 34; a plurality of the straight heating segments 31 are evenly arranged on the lower aluminum foil membrane 2 from the left side to the right side thereof; two adjacent straight heating segments 31 are connected in series through a circular arc heating segment 32; the first power-connected heating segment 33 is connected to the leftmost straight heating segment 31; the second power-connected heating segment 34 is connected to the rightmost straight heating segment 31. Preferably, the circular arc heating segment 32 is a semicircular arc line structure. A plurality of straight heating segments 31 are evenly arranged from the left side to the right side of the lower aluminum foil membrane 2, and then connected in series through the circular arc heating segment 32 between two adjacent straight heating segments 31, and then electrically connected to the terminal connection module 6 through the first power-connected heating segment 33 and the second power-connected heating segment 34 to realize structural power supply.

[0031] With this design, the heating wire 3 is in close contact with the aluminum foil film, and the excellent thermal conductivity of the aluminum foil is utilized to better achieve rapid and uniform heat transfer, effectively solving the problem of fogging of the bathroom mirror.

[0032] The distance between two adjacent straight heating segments 31 is 10-15 mm, specifically 10 mm, 12 mm, or 15 mm. Reasonable design of the distance between two adjacent straight heating segments 31 is beneficial for enhancing the uniformity of heat transfer of the bathroom mirror heating film, effectively solving the problem of fogging the bathroom mirror.

[0033] In this embodiment, the thickness of the upper aluminum foil film 1 and the lower aluminum foil film 2 is 0.1-0.2 mm, preferably 0.1 mm.

[0034] In summary, the embodiment of the present invention provides a heating film for a bathroom mirror, wherein, on the basis of the upper aluminum foil film 1, the lower aluminum foil film 2 and the heating wire 3, the lower aluminum foil film 2 is improved, and a coiling wire groove 21 and a glue groove 22 are opened on the lower aluminum foil film 2 by stamping. After the heating wire 3 is adapted and embedded in the coiling wire groove 21, the heating wire 3 is fixed in each glue groove 22 by a first high-temperature double-sided tape 4, and then the upper aluminum foil film 1 and the lower aluminum foil film 2 are connected by a second high-temperature double-sided tape 5. In this design, the coiling wire groove 21 is used to accurately position the heating wire 3, and then the first high-temperature double-sided tape 4 is used to firmly fix the heating wire 3 in the glue groove 22, which simplifies the installation process, reduces the installation difficulty, and makes the installation more convenient. At the same time, it effectively prevents loosening or displacement during the heating process, ensures uniform heat transfer, avoids the clutter in traditional wiring methods, and improves the overall aesthetics and structural stability of the structure.

It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present application. These improvements and replacements should also be regarded as the scope of protection of the present application.
