Description

Technical Field

[0001] The invention relates to a multi-curved surface heat conduction mold for a hair straightener, in particular to a multi-curved surface heat conduction mold for a hair straightener, and belongs to the technical field of hair straighteners. Background Art

[0002] The working principle of a hair straightener is to generate heat through a heating element, which is evenly transferred to the working surface of the hair straightener (i.e., the clamping plate part) through a heat conduction mold, thereby heating and styling the hair. The multi-curved heat conduction mold is designed to better fit the shape of the hair, ensure uniform heating, and reduce local overheating or insufficient heating. This design not only improves heating efficiency and shortens styling time, but also helps protect hair quality and reduce heat damage. During installation, the multi-curved heat conduction mold is usually tightly connected to the heating element and clamping plate part of the hair straightener to ensure effective heat transfer. At the same time, the material and manufacturing process of the mold also need to meet certain requirements to ensure its thermal conductivity, structural strength and durability. Therefore, it can be said that the multi-curved heat conduction mold of the hair straightener is an important part of the hair straightener, and plays a key role in improving the performance and user experience of the hair straightener.

[0003] Chinese patent announcement number CN220069084U discloses "a hair straightener, comprising hinged clamping plate a and clamping plate b, clamping plate a is provided with heat conductive sheet a on the side facing clamping plate b, clamping plate b is provided with heat conductive sheet b on the side facing clamping plate a, the heat conductive sheet a is provided with a limit surface tilted toward the heat conductive sheet b at at least one end along its length direction, and the heat conductive sheet b is provided with a fitting surface fitted with the limit surface. By adopting the above technical solution, the utility model provides a hair straightener, the heat conductive sheet is provided with a limit surface that can limit the hair from leaving the heat conductive sheet, thereby improving the working efficiency of the heat conductive sheet and shortening the time of hair straightening";

[0004] The above patent has certain defects: for example, it lacks a drying function. For users who need to use a hair straightener to style their hair but their hair is still wet, the lack of a blowing structure means that they need to use a hair dryer to dry their hair before using the hair straightener.

DETAILED DESCRIPTION

[0036] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0037] like Figure 1 and Figure 2 As shown, the multi-curved heat conduction mold of the hair straightener provided in this embodiment includes a hair straightener body 1 composed of a hair straightener body 101, a multi-curved heat conduction clamp 102 installed on the hair straightener body 101, a control button 103 and a connecting wire 104. The number of the hair straightener body 101 and the multi-curved heat conduction clamp 102 are both two, the two hair straightener bodies 101 are arranged opposite to each other, and one end of each is elastically hinged, and the two multi-curved heat conduction clamps 102 are fixed to the opposite sides of the two hair straightener bodies 101. It should be noted that the multi-curved heat conduction mold (i.e., the multi-curved heat conduction clamp 102) is usually combined with a temperature control system, allowing the user to adjust the heating temperature as needed. The temperature adjustment function (i.e., the control button 103) is essential for different types of hair and styling requirements. For example, fine and soft hair may require a lower temperature to avoid overheating damage, while coarse and hard hair requires a higher temperature to achieve an ideal straightening effect. By adjusting the temperature, the user can optimize the performance of the hair straightener, reduce damage to the hair, and achieve a more natural straightening effect.

[0038] In this embodiment, if Figure 2-Figure 9As shown, the outer surface of the hair straightener body 101 is detachably mounted with a functional mechanism 2; the detachable mounting design of the hair straightener body 101 and the functional mechanism 2 allows the user to replace or upgrade the functional mechanism 2 as needed, thereby extending the service life of the hair straightener and meeting different usage requirements. The overall design takes into account the user's operational convenience and comfort, making the use process more pleasant and easy. The functional mechanism 2 includes a mounting shell 201, a nozzle 202 and a water storage structure 204 fixed inside the mounting shell 201, a fan 203 mounted on the top of the nozzle 202, and a connecting pipe 205 fixed between the water storage structure 204 and the nozzle 202; as shown Figure 5-Figure 8 As shown, the nozzle 202 includes a first expansion tube 2021, a second expansion tube 2022 and a throat 2023, wherein the throat 2023 is composed of a telescopic tube 1 20231 and a telescopic tube 20232 connected in a telescopic manner, and an adjustment mechanism 3 is provided between the first expansion tube 2021 and the second expansion tube 2022; the hair straightener not only has the traditional hair straightening function, but also realizes the dual functions of blowing and sprinkling (or spraying) by integrating components such as the nozzle 202, the fan 203 and the water storage structure 204. This design allows the user to replenish moisture to the hair, protect the hair quality and reduce damage caused by high temperature while using the hair straightener for styling. Figure 8 As shown, a valve 206 is arranged inside the connecting pipe 205, and a linkage structure 4 is installed between the telescopic tube 20232 and the connecting pipe 205 to cooperate with the regulating mechanism 3 and to regulate the opening and closing of the valve 206. The linkage structure 4 includes a connecting shaft 401 fixed to the top side of the valve 206, a rack 403 slidably arranged on the outer surface of the connecting pipe 205, a gear 402 fixed to the other end of the connecting shaft 401 and meshing with the rack 403, a connecting rod 404 hingedly installed between the telescopic tube 20232 and the rack 403, and a guide member installed inside the connecting pipe 205 for guiding the rack 403.

[0039] Specifically, Figure 3 and Figure 4As shown, a cavity 2011 is provided inside the mounting shell 201, an air outlet 210 communicating with the cavity 2011 and the outside is provided on the bottom side of the mounting shell 201, a mounting hole 209 for mounting and fixing is provided on the side of the mounting shell 201 close to the hair straightener body 101, and an inspection cover 208 is detachably installed on the outer surface of the mounting shell 201. The design of the inspection cover 208 on the outer surface of the mounting shell 201 allows the user to easily open the shell to inspect, clean or replace the internal components. This design improves the durability and maintainability of the hair straightener. The design of the cavity 2011 and the vent hole and other structures also facilitates the user to perform daily cleaning and maintenance work. The nozzle 202 is fixed in the cavity 2011, and the bottom end of the first expansion tube 2021 is bolted with a bottom shell 2024, and the lower surface of the bottom shell 2024 is installed with an elastic connection cover 2025 fixed to the inner wall of the cavity 2011.

[0040] To realize the operation of the fan 203, in this embodiment, the first expansion tube 2021 and the second expansion tube 2022 are connected vertically, and the first expansion tube 20231 and the second expansion tube 20232 are provided with through holes 207 connected with the first expansion tube 2021 and the second expansion tube 2022. The bottom shell 2024 is hollow inside, and its upper and lower sides are respectively connected with the through holes 207 and the elastic connection cover 2025. A vent hole connected with the outer surface is provided inside the mounting shell 201 to realize the operation of the fan 203. A limiter is provided between the first expansion tube 20231 and the second expansion tube 20232 to ensure their stable expansion and contraction.

[0041] like Figure 5 and Figure 6 As shown, the water storage structure 204 includes a water storage cylinder 2041 fixed to the outer surface of the bottom shell 2024, a connecting pipe 2042 fixedly connected to the upper surface of the water storage cylinder 2041, and a water supply pipe 2043 fixedly connected to the other end of the connecting pipe 2042, and the water supply pipe 2043 extends to the outside of the mounting shell 201. The water supply pipe 2043 can be used as an external pipe. The throat 2023 is smaller in shape than the first expansion pipe 2021 and the second expansion pipe 2022. In addition, the water storage cylinder 2041 adopts a high-strength structure, and a reinforcement frame can be installed in the water storage cylinder 2041 to ensure the strength of the water storage cylinder 2041. The through hole 207 opened inside the nozzle 202 and the design of the bottom shell 2024 and the elastic connection cover 2025 ensure that the airflow generated by the fan 203 can smoothly pass through the nozzle 202 and act on the hair evenly. This efficient airflow distribution helps to dry the hair quickly while reducing heat damage. In addition, the watering (or spraying) function transports the water in the water storage structure 204 to the nozzle 202 through the connecting pipe 205, and then sprays it out in the form of atomization to replenish moisture for the hair and keep the hair smooth and shiny.

[0042] like Figure 7-Figure 9As shown, the adjustment mechanism 3 includes a mounting platform 301 fixed to the outer surface of the first expansion tube 2021 and the second expansion tube 2022, a motor 302 fixed to the upper surface of the top side mounting platform 301, and a lead screw 303 with a bearing mounted between the two mounting platforms 301. The motor 302 drives the lead screw 303 to rotate, and the axial movement of the connecting block 304 along the lead screw 303 can be accurately controlled. Since the connecting block 304 is fixed to the telescopic tube 20231, the length of the throat 2023 of the nozzle 202 can be easily adjusted. This ability of precise adjustment allows the user to customize the intensity and range of the watering (or spraying) function according to actual needs, such as the length, thickness and desired styling effect of the hair, thereby providing a more personalized use experience. Through the ingenious design of the adjustment mechanism 3 and the linkage structure 4, the user can easily adjust the length of the throat 2023 of the nozzle 202, thereby controlling the opening and closing of the valve 206. This design allows the watering (or spraying) function to be accurately adjusted according to user needs, providing a more personalized use experience. The telescopically connected telescopic tube 1 20231 and telescopic tube 2 20232 allow the user to adjust the length and shape of the nozzle 202 as needed, increasing the flexibility of use. The top of the lead screw 303 is fixed to the output shaft of the motor 302, the external thread of the lead screw 303 is connected to the connecting block 304, and one side of the connecting block 304 is fixed to the outer surface of the telescopic tube 1 20231, the inside of the connecting tube 205 is provided with a through hole, and the end of the connecting shaft 401 away from the valve 206 passes through the through hole and extends to the outside of the connecting tube 205, and a sealing structure is provided at the connection between the connecting shaft 401 and the through hole.

[0043] To achieve stable transmission, Figure 8 and Fig. 9 As shown, the guide member includes a guide rod 406, a slider 407 sleeved and mounted on the outer surface of the guide rod 406, and a cushion block 408 fixed to the outer surface of the slider 407, and the side of the cushion block 408 away from the slider 407 is fixed to the outer surface of the rack 403. The interior of the connecting pipe 205 is provided with a mounting groove 405 connected to the outer surface, the guide rod 406 is fixed in the mounting groove 405, and a buffer spring 409 is fixed on the outer surface of the slider 407 and one side of the mounting groove 405, and the buffer spring 409 surrounds the outer surface of the guide rod 406. The buffer spring 409 surrounds the outer surface of the guide rod 406 and is connected between the slider 407 and one side of the mounting groove 405. This design provides additional buffering and shock absorption functions, which helps to reduce the impact and vibration that may be generated during the adjustment process. This can not only improve the durability and stability of the equipment, but also reduce the noise level and provide a more comfortable use environment.

[0044] When the embodiment is in use, the adjustment mechanism 3 and linkage structure 4 in the design of the hair straightener bring many benefits and advantages such as precise adjustment, stable transmission, buffering and shock absorption, easy maintenance and repair, and flexible adaptation. These design features not only improve the performance and durability of the device, but also provide users with a more comfortable and personalized use experience.

[0045] like Figure 1-Figure 9 As shown, the principle of the multi-curved heat conduction mold of the hair straightener provided in this embodiment is as follows:

[0046] When the present invention is used, the fan 203 is started, and the Laval principle nozzle 202 is used to send air out from the air outlet 210 to achieve blowing when the hair is straight. Then, the throat 2023 in the nozzle 202 is extended through the adjustment mechanism 3. When the throat 2023 is extended, the rack 403 is driven by the connecting rod 404. The displacement of the rack 403 drives the gear 402 to rotate, thereby opening the valve 206. When the fan 203 is working, blowing can generate airflow, which is used to blow the water in the water storage cylinder 2041 and transport it through the connecting pipe 205, and finally spray it out through the nozzle 202 to achieve the watering function.
