Description

Technical Field

[0001] This utility model relates to the field of hair curlers, specifically to a light-emitting, high-temperature resistant hair curler. Background Technology

[0002] As a common hair styling tool, curling brushes are constantly evolving towards greater functionality. Among them, curling brushes that emit light and possess heat-resistant properties have garnered widespread attention from consumers. These curling brushes not only fulfill basic curling functions, but their light-emitting design allows users to more clearly observe the hair's condition during styling, while their heat-resistant properties adapt to the high-temperature environments generated during operation.

[0003] When reassembling common curling combs, the light panel is usually tied to the nylon bristles with cable ties (without an aluminum tube). This manual installation is very difficult, resulting in low production volume, high labor costs, and insufficient output. To address this issue, some factories directly assemble PCBA components (with ordinary high-temperature resistant LEDs and true infrared lamps emitting 850nm invisible light) in the middle of the aluminum tube. However, while ordinary high-temperature resistant LEDs have some heat resistance, they are difficult to adapt to the high-temperature environment of curling comb operation and are prone to failure due to high temperatures during prolonged use, failing to provide continuous and stable illumination. Therefore, we propose a high-temperature resistant, luminous curling comb. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned defects and provide a light-emitting, high-temperature resistant curling comb that avoids structural deformation and damage caused by high temperatures during use. This invention solves the technical problem in the prior art where the high temperature generated at the center of the aluminum tube where the light assembly is mounted easily causes structural deformation and damage.

[0005] The objective of this utility model is achieved through the following means:

[0006] A high-temperature resistant, luminescent curling comb includes a handle. A connector is snapped into the internal opening of the handle. A heat-conducting tube is inserted inside the connector. A bracket is connected to the outside of the heat-conducting tube. A plug is snapped into the inside of the bracket. Long strips are inserted into both sides of the heat-conducting tube. A PCB motherboard is also housed inside the handle. A button is connected to the control port of the PCB motherboard. A female connector assembly is snapped into the tail opening of the handle. A tail ring is fitted onto the outside of the female connector assembly. A power cord electrically connected to the PCB motherboard is located inside the tail ring. PCT boards are inserted into both sides of the inside of the connector. PTC extended springs are laid on the inner side of the PCT boards. A mica sheet is installed in the center of the inner side of the connector, and a copper busbar is laid on the surface of the mica sheet. A tungsten filament lamp is electrically connected to the copper busbar. A dual-color electronic lead is electrically connected to the interface of the copper busbar. Positioning holes are evenly distributed on the surface of the copper busbar. Rivets are inserted into the positioning holes, and the copper busbar is fixed to the surface of the mica sheet by the rivets.

[0007] Furthermore, a nylon comb and hair implantation assembly is inserted inside the heat-conducting pipe. The nylon comb and hair implantation assembly includes a hair implantation roller and a comb. Through holes are circumferentially opened on the surface of the heat-conducting pipe, and the combs of the nylon comb and hair implantation assembly all penetrate through the through holes on the surface of the heat-conducting pipe.

[0008] Furthermore, the handle also houses a negative ion generator electrically connected to the PCB motherboard. A decorative cover is inserted inside the upper handle at a position corresponding to the connector. The handle includes an upper handle and a lower handle, with the upper handle mounted on top of the lower handle. A lens is inserted in the center of the surface of the upper handle. The negative ion generator is located inside the handle, complementing the decorative cover and the lens in the center of the upper handle. The negative ion generator releases ions during curling, reducing static electricity and making hair smoother and softer. The decorative cover facilitates maintenance of the negative ion generator components. The lens allows users to easily observe the hair styling process, enhancing the user experience and styling effect.

[0009] Furthermore, a thermally conductive adhesive layer is laid between the mica sheet and the copper busbar. This thermally conductive adhesive layer is evenly applied to the surface of the mica sheet. Positioning holes are drilled in the surface of the copper busbar, through which rivets are inserted to connect it to the mica sheet, with the thermally conductive adhesive layer between them. The rivet connection ensures a stable connection between the copper busbar and the mica sheet, preventing loosening. The evenly applied thermally conductive adhesive layer efficiently conducts heat, allowing the heat generated by the tungsten filament lamps mounted on the copper busbar surface of the mica sheet to dissipate quickly, thus improving the high-temperature resistance and luminous stability of the curling comb.

[0010] Furthermore, the upper handle's mounting surface is connected to locating pins, and the bottom ends of these pins are all spherical. The locating pins are evenly distributed along the edge of the upper handle. Correspondingly, the lower handle's mounting surface has sockets at positions corresponding to the locating pins. The locating pins are inserted into the sockets. Both the locating pins and sockets have through-hole threaded holes, and screws are screwed into these threaded holes. This structure ensures precise handle assembly, facilitates insertion of the spherical locating pins, and enhances connection strength with screw fixation, preventing handle loosening during use and improving safety.

[0011] Furthermore, the PTC extended spring is equipped with a circular terminal on its exterior, and a copper dielectric is inserted inside the circular terminal. The copper dielectric and the circular terminal are electrically connected by an NTC wire. The PCT plate and the mica sheet both extend into the interior of the heat pipe and are arranged along the length of the heat pipe.

[0012] Furthermore, the connector is internally filled with heat-insulating silicone. The dual-color electronic leads and NTC wires both penetrate the connector and the heat-insulating silicone. The dual-color electronic leads and NTC wires are each covered with a yellow adhesive paper sleeve. The heat-insulating silicone is inserted into the connector, through which the dual-color electronic leads and NTC wires pass and are covered with yellow adhesive paper sleeves. The heat-insulating silicone effectively blocks the high-temperature conduction of the heat pipe, protecting the internal circuitry; the yellow adhesive paper sleeves enhance the insulation of the wires. Together, these two elements ensure the safe and stable operation of the curling comb's circuitry under high-temperature conditions.

[0013] Furthermore, an annular groove and an annular protrusion are provided between the heat-insulating silicone and the inner wall of the connector. The annular protrusion is located at the outer edge of the heat-insulating silicone, and the annular groove is located at a corresponding position on the inner wall of the connector. The annular protrusion is inserted into the annular groove. Heat-shrinkable sealing ends are provided at both ends of the yellow adhesive paper sleeve. These heat-shrinkable sealing ends are tightly wrapped around the connection points of the dual-color electronic leads and NTC wires with the yellow adhesive paper sleeve by heat shrinking. The heat-insulating silicone and the inner wall of the connector are engaged by the annular groove and the annular protrusion, and the yellow adhesive paper sleeve has heat-shrinkable sealing ends at both ends. The annular structure ensures stable installation of the heat-insulating silicone and better heat insulation; the heat-shrinkable sealing ends tightly wrap around the wire connection points to prevent dust and other contaminants from entering, enhancing insulation and ensuring the curling comb operates safely and reliably in high-temperature environments.

[0014] The beneficial effects of this utility model are:

[0015] This solution integrates the structure of the lamp board, including mica sheet, copper busbar, and tungsten filament lamp, with the connector of the curling comb. This facilitates the industrial manufacturing and installation of the structural components, avoiding the low installation efficiency caused by manually binding the lamp strip to the nylon bristles of the curling comb with cable ties. This reduces labor costs and increases manufacturing output.

[0016] This solution uses mica sheets instead of traditional PCB substrates. Because mica sheets have high-temperature resistance, they remain stable in high-temperature environments, providing reliable support for internal components and effectively preventing structural deformation and damage caused by high temperatures. Furthermore, tungsten filament lamps replace traditional LED lamps. Due to their excellent high-temperature resistance, tungsten filament lamps can withstand the high temperatures generated by the curling comb, ensuring continuous and stable illumination during prolonged use without failure due to high temperatures. Simultaneously, by fixing copper busbars to the mica sheets with rivets, the solution is more robust and durable than traditional thin copper sheets, able to withstand high temperatures without warping or deformation, ensuring stable circuit connections. This allows the curling comb to emit light safely, stably, and continuously in high-temperature operating environments, improving product reliability and safety, and providing users with a superior and reassuring user experience.

[0027] In this embodiment, refer to Figure 1 - Figure 8 The present invention relates to a light-emitting, high-temperature resistant curling comb, comprising an upper handle 1 and a lower handle 2.

Both PCT board 15 and mica sheet 16 extend into the interior of heat pipe 3 and are arranged along the length of heat pipe 3. The structure of the lamp board, including mica sheet 16, copper busbar 21, and tungsten filament lamp 22, is structurally integrated with the connector 7 of the hair curling comb. This facilitates the industrial manufacturing and installation of the structural components, avoiding the problem of low installation efficiency caused by manually binding the light strip to the nylon bristles of the hair curling comb with cable ties, reducing labor costs and increasing manufacturing output.

[0028] By replacing the traditional PCB substrate with mica sheet 16, the mica sheet 16, with its high-temperature resistance, can remain stable in high-temperature environments, providing reliable support for internal components and effectively preventing structural deformation and damage caused by high temperatures. Furthermore, by replacing the traditional LED light with a tungsten filament lamp 22, the tungsten filament lamp 22, with its excellent high-temperature resistance, can adapt to the high temperatures generated by the curling comb, ensuring continuous and stable illumination during long-term use without failure due to high temperatures. At the same time, by fixing the copper busbar 21 to the mica sheet 16 with rivets, it is more stable and durable than the traditional thin copper sheet, able to withstand high temperatures without warping or deformation, ensuring stable circuit connections. This allows the curling comb to emit light safely, stably, and continuously in high-temperature working environments, improving the reliability and safety of the product and bringing users a better and more reassuring user experience.

[0029] The upper handle 1 and the lower handle 2 are electrically connected to the negative ion generator 9 on the outside of the PCB motherboard 8.

The dual-color electronic lead 23 and the NTC wire 18 are covered with yellow adhesive paper sleeves.

[0030] The surface of the copper busbar 21 is evenly provided with positioning holes, and rivets are inserted into the positioning holes.

The annular protrusion is inserted into the annular groove. Heat-shrinkable sealing ends are provided at both ends of the yellow adhesive paper sleeve. The heat-shrinkable sealing ends are tightly wrapped around the connection between the dual-color electronic lead 23 and the NTC wire 18 and the yellow adhesive paper sleeve by heating and shrinking.

[0031] This solution replaces the traditional PCB substrate with a mica sheet 16. Due to its high-temperature resistance, the mica sheet 16 remains stable in high-temperature environments, providing reliable support for internal components and effectively preventing structural deformation and damage caused by high temperatures. Furthermore, it replaces the traditional LED light with a tungsten filament lamp 22. The tungsten filament lamp 22 has excellent high-temperature resistance, adapting to the high temperatures generated by the curling comb, ensuring continuous and stable illumination during prolonged use without failure due to high temperatures. Simultaneously, by fixing the copper busbar 21 to the mica sheet 16 with rivets, it is more stable and durable than traditional thin copper sheets, able to withstand high temperatures without warping or deformation, ensuring stable circuit connections. This allows the curling comb to emit light safely, stably, and continuously in high-temperature operating scenarios, improving product reliability and safety, and providing users with a better and more reassuring user experience.
