[0022] Hair straighteners are typically equipped with a fan to blow dry your hair while straightening. However, existing hair straighteners typically have a one-way air outlet, resulting in extremely uneven airflow. As a result, drying efficiency is reduced during use, and hair is not dried evenly. Furthermore, a one-way air outlet means that hair is exposed to uneven airflow during drying, causing frizz, significantly detracting from the overall user experience.

[0023] In order to solve the above problems, an example of the implementation of the present utility model proposes a hair straightener, further, in combination with the text and the attached drawings, the specific structure and functional features of the hair straightener proposed in the example of the implementation of this utility model will be described in detail.

[0024] As shown in Fig. 1-7, the hair straightener proposed in the embodiment of the present utility model includes: a lower clamping device 100 and an upper clamping device 200, the lower clamping device 100 includes a lower housing 110, a lower heating component 120 and a fan 130. The lower housing 110 is made of high-strength plastic with a certain elasticity and heat resistance, which ensures its stability and prevents deformation or damage during long-term use.

[0025] The upper side of the lower body 110 is flat, and it is divided along the length into a hand-held part and a hair straightening part, the hand-held part is cylindrical, and the straightening part is flat, the lower heating component 120 is placed in the hair straightening part of the lower body 110 and protrudes on the upper surface of the lower body 110, during use, the heat generated by the lower heating component 120 is transferred to the hair, achieving effective straightening.

[0026] The lower body 110 is equipped with an air inlet 111 and an air outlet 112. The air inlet 111 is located on the handpiece, at the end remote from the lower heating element 120. Its shape and width can be optimally selected based on the overall structure of the hair straightener and the required air volume to ensure sufficient air flow. The air outlet 112 is located in the hair straightening section and covers the lower heating element 120.

[0027] The lower body hand portion 110 is formed approximately cylindrical to form an internal air intake duct, the fan 130 is installed inside the air intake duct between the air intake port 111 and the air outlet 112, a high-speed fan 130 is used that provides a large air volume with low noise, and allows the air sucked in through the air intake port 111 to be uniformly discharged through the air outlet 112.

[0028] The upper clamping device 200 includes an upper housing 210 and an upper heating component 220. The upper housing 210 is connected to the lower housing 110 via a hinge or axis, which allows the upper housing 210 to rotate toward or away from the lower housing 110, facilitating the clamping and release of hair. The upper heating component 220 is mounted on the upper housing 210 on the side facing the lower heating component 120, and together with the lower heating component 120, it provides heating and straightening of hair.

[0029] In the actual working process, when the user uses the hair straightener of this utility model, the hair is first divided into several strands, after which one strand is placed on the lower heating component 120, then the upper body 210 is rotated so that the upper heating component 220, together with the lower heating component 120, clamps the strand of hair. At this moment, the power of the hair straightener is turned on, the lower heating component 120 and the upper heating component 220 begin to heat up, and the fan 130 is simultaneously driven, sucking in air through the air inlet 111 and uniformly blowing it out through the air outlet 112, achieving drying and straightening of the hair. During the straightening process, thanks to the uniform air flow, the hair dries quickly and evenly, without causing a frizzy effect.

[0030] As shown in Fig. 6 and 7, alternatively, a fan circuit board 130 may be installed inside the air intake duct, and during operation, air sucked in through the air intake port 111 and passed through the air outlet port 112 is capable of removing heat generated by the electronic components on the circuit board, thereby achieving cooling.

[0031] In the hair straightener illustrated in the exemplary embodiment of this utility model, air exits from the air outlet 112, which envelops the lower heating element 120, in multiple directions. This multi-directional airflow significantly improves the uniformity of the airflow: the airflow evenly covers the hair, affecting all sections simultaneously, allowing for quick and even drying. At the same time, thanks to the uniform airflow, the hair is not frizzed due to the strong localized airflow, providing a better blow-drying effect and overall user experience.

[0032] Alternatively, a grille may be installed on the air outlet 112 to form a plurality of evenly distributed small holes, the diameter of these small holes being small and allowing the air flow to be more evenly distributed throughout the surrounding space while maintaining the overall air volume.

[0033] Alternatively, since the hair straightener's air intake duct does not contain heating elements, it delivers a relatively low-temperature, uniform airflow that hits the hair at close range, promoting more effective drying. Furthermore, the low-temperature airflow quickly cools the styled hair, locking in shape and reducing damage from residual heat after styling.

[0034] As shown in Fig. 8 and 9, in some embodiments, the air outlet 112 may also be located in the upper housing 210, in which case an air duct tube 160 is provided on the lower housing 110, and an air inlet 230 is located on the side of the upper housing 210 facing the lower housing 110, when the user rotates the upper housing 210 so that the upper heating component 220 and the lower heating component 120 clamp the hair, the air duct tube 160 on the lower housing 110 is connected to the air inlet 230 on the upper housing 210, when the fan 130 is operating, air enters through the air inlet 111, then passes through the air duct tube 160 and the air inlet 230 into the upper housing 210, and ultimately exits through the air outlet 112 on the upper housing 210.

[0035] Alternatively, a grille and filter may be installed in the air inlet 230 to prevent foreign matter from entering.

[0036] As shown in Fig. 2-4, the hair straightener according to the embodiment of the present utility model further includes an air duct component 140, when the air outlet 112 is located in the lower housing 110, the air duct component 140 is located inside the lower housing 110, and when the air outlet 112 is located in the upper housing 210, the air duct component 140 is located inside the upper housing 210. The air duct component 140 includes an upper air guide body 141 and a lower air guide body 142, which are connected to each other using a clamp or fixed with screws.After connecting the lower air guide body 142 and the upper air guide body 141, an air duct inlet 143 and an air guide channel 144 are formed inside, which envelops the lower heating component 120, the air guide channel 144 has an approximately U-shaped form, which makes it possible to create a relatively stable air flow direction inside the channel, reducing turbulence and energy loss.

[0037] The air inlet 143 of the duct is located at the end of the air duct component 140, near the fan 130. When the fan 130 operates, the air sucked through the air inlet 111 first enters the air inlet 143 of the duct, and then is guided to move along the air guide channel 144. Since the air guide channel 144 wraps around the lower heating component 120, the air flow can be discharged around the lower heating component 120 when moving.

[0038] An air duct outlet 145 is provided on the upper air guide body 141, this outlet 145 connects the air outlet 112 and the air guide channel 144. After passing through the air guide channel 144, the air flow is discharged through the air duct outlet 145 as a uniform air flow, achieving drying and straightening of the hair located between the upper heating component 220 and the lower heating component 120. This not only improves the uniformity of the air flow, but also allows the heat to act more effectively on the hair, improving the overall performance and operating efficiency of the hair straightener.

[0039] Alternatively, the air duct component 140 may be fixed to the lower housing 110 or the upper housing 210 using a clamp or screws to ensure a secure connection.

[0040] Alternatively, in addition to installing the air duct component 140, a solid multi-section partition can be formed inside the lower housing 110 or the upper housing 210, this multi-section partition in combination with the wall of the lower housing 110 is also capable of forming an air guide channel 144.

[0041] According to Fig. 2-4, in an embodiment of the present utility model, the hair straightener includes an air guide channel 144, which consists of two first air ducts and a second air duct, the two first air ducts are located on both sides of the lower heating component 120, the second air duct and the inlet of the air duct 143 are located at opposite ends of the two first air ducts, wherein the second air duct connects the two first air ducts, and the inlet of the air duct 143 is directly connected to the two first air ducts, this allows the air entering through the inlet of the air duct 143 to quickly separate and be directed into the two first air ducts, and then enter the second air duct.

[0042] A guide plate 146 is installed on the first air guide body. This guide plate 146 is located in the middle of the air duct inlet 143, with inclined surfaces on both sides that guide air into the first two air ducts. When the fan 130 operates, air is sucked through the air inlet 111 into the air intake duct of the handpiece and reaches the air duct inlet 143, where the guide plate 146 evenly and simultaneously distributes the air flow into the first two air ducts.For example, when the air flow meets the guide plate 146 in the inlet opening 143 of the air duct, due to the guiding function of the guide plate 146, part of the air flow is directed along the inclined surface on one side of the guide plate 146 into one first air duct, and the other part of the flow is directed along the inclined surface of the guide plate 146 on the other side of the plate into another first air duct, which ensures rational distribution of the air flow.

[0043] The first two air ducts are arranged in parallel, and air duct outlet openings 145 are installed on their upper portions, so that the divided air flow can be discharged both through the air ducts and through the air outlet opening 112. The second air duct is located at the end of the air duct component 140, remote from the air duct inlet opening 143, and an air duct outlet opening 145 is also installed on its upper portion, so that the air flow collected from the first two air ducts can be discharged through the air duct outlet opening 145.

[0044] According to Fig. 3 and 4, in the hair straightener shown in this embodiment of the utility model, protrusions are formed on the wall of the lower air guide body 142, forming guide ribs 147, wherein the guide ribs 147 extend from the inlet opening 143 of the air duct to the outlet opening 145 of the air duct, during operation, when the fan 130 is turned on, the air sucked through the air intake opening 111 enters the inlet opening 143 of the air duct and then moves along the air guide channel 144. At this moment, the guide ribs 147 located on the lower wall of the air guide channel 144 provide a directed air flow, due to which the air can exit through the outlet opening 145 of the air duct located above.

[0045] As shown in Fig. 2-4, in the hair straightener shown in this embodiment of the utility model, the lower heating component 120 includes a mounting frame 121, a heating plate 122 and an ironing plate 123, wherein the heating plate 122 and the ironing plate 123 are fixed on the mounting frame 121, a recess is made on the upper side of the upper air guide body 141, forming a mounting groove 148, the mounting frame 121 is fixed in the mounting groove 148 using screws, which makes it possible to increase the compactness of the entire structure.

[0046] Alternatively, the 121 mounting frame has a certain heat resistance and can withstand part of the heat load generated during the hair straightening process. The outer side of the ironing plate 123 is made predominantly flat, which ensures its full contact with the user's hair, and on the inner side of the ironing plate 123, two fastening plates 124 are located at an interval, on the outer sides of the two fastening plates 124, clamps are provided that engage with the fastening frame 121, the heating plate 122 is placed on the inner side of the ironing plate 123 and is located between the two fastening plates 124, wherein the two fastening plates 124 are curved in such a way as to partially cover the heating plate 122, during use, the heat emitted by the heating plate 122 is directly transferred to the ironing plate 123, which allows for the effective straightening of the user's hair.

[0047] It should be noted that the heating plate 122 is a PTC thermal plate, and the ironing plate 123 is made of pure aluminum by cold pressing. After pressing, the material density becomes higher and more uniformly distributed. The ironing plate material is pure aluminum or AL1050 / 1070 alloy, and the thermal conductivity coefficient can reach more than 231W / (m⋅K). The thickness of the ironing plate 123 can be limited to ≤0.9mm. Since the ironing plate 123 is thin enough and made of pure aluminum with a high thermal conductivity, the heat transfer efficiency of the heating plate 122 is greatly improved. During use, even if the hair absorbs some of the heat, the cold pressing technology of pure aluminum ensures that the ironing plate 123 heats up and recovers its temperature faster, effectively improving the efficiency of hair straightening.

[0048] Alternatively, the lower heating component 120 may also include a pressure cover 125, the pressure cover 125 is located between the ironing plate 123 and the fastening frame 121, when the two fastening plates 124 bend, they simultaneously embrace the heating plate 122 and the pressure cover 125, ensuring that the heating plate 122 and the pressure cover 125 are securely fixed.

[0049] It should be noted that the pressure cover 125 has certain heat-insulating properties, which can reduce the heat transfer from the heating plate 122 to the mounting frame 121, due to which the heat of the heating plate 122 is transferred to the ironing plate 123 as efficiently as possible, ensuring its faster heating.

[0050] It should be noted that the upper heating component 220 and the lower heating component 120 have the same composition and structure, which ensures the interchangeability of parts during assembly.

[0051] Alternatively, a heat insulating plate 126 is further installed between the mounting frame 121 and the upper air guide body 141, and the heat insulating plate 126 may be made of a heat-insulating fiber-based aerogel, which reduces heat transfer from the mounting frame 121 to the upper body 210, due to which the air discharged from the hair straightener is close to room temperature, which can quickly cool the hair and reduce the thermal impact on it during straightening.

[0052] According to Fig. 1 and Fig. 6, the hair straightener according to the embodiment of the utility model further includes a control unit 300, the control unit 300 consists of a control panel 310, a blowing control button 320, a heating control button 330 and a power control button 340, the control panel 310 is located inside the upper body 210 and performs important functions of processing signals and transmitting commands. The blowing control button 320, the heating control button 330 and the power control button 340 are connected to the upper body 210 and protrude on the outer surface of the upper body 210, which is convenient for users. These buttons have a shape that is easy to press, and appropriate markings can be applied to their surface to clearly indicate their functions.

[0053] The blowing control button 320 is electrically connected to the control panel 310 and the fan 130, when the user presses the blowing control button 320, a signal is transmitted to the control panel 310, and the control panel 310, in turn, controls the turning on and off of the fan 130 according to the received command. For example, when it is necessary to use the blowing function of the hair straightener, the user only needs to press the blowing control button 320, the fan 130 will start to work, drawing in external air, which passes through the air guide channel 144 and is discharged through the air outlet 112; when this button is pressed again, the fan 130 stops.

[0054] The heating control button 330 is also electrically connected to the control panel 310, the upper heating component 220 and the lower heating component 120. The user can turn on or off the upper heating component 220 and the lower heating component 120 by pressing the heating control button 330. When the heating control button 330 is pressed to turn on the heating function, the control panel 310 transmits a command to the upper heating component 220 and the lower heating component 120 to supply electricity, as a result of which they begin to generate heat necessary for straightening the hair; when the heating function is turned off, the control panel 310 cuts off the supply of electricity, stopping the heating of the components.

[0055] Power control button 340 is electrically connected to control panel 310 and functions as the main power switch. Pressing power control button 340 supplies power to the hair straightener, switching it to standby or operating mode. Pressing it again interrupts the power supply, stopping operation. This allows the user to conveniently control the power on and off of the hair straightener, ensuring safety and convenience. For example, when not using the hair straightener for a long time, the user can completely turn off the device by pressing power control button 340, avoiding unnecessary energy consumption and potential safety risks.

[0056] Alternatively, the control unit 300 may also include power level indicators, several such indicators may be installed on the side of the blowing control button 320 and the side of the heating control button 330, for example, three power level indicators are located on one side of the blowing control button 320 and the heating control button 330, which display different power levels, by pressing the blowing control button 320 and the heating control button 330, different power levels can be switched.

[0057] Alternatively, heating plate 122 is designed as a PTC plate and is equipped with a temperature sensor on one side. The user can adjust the temperature using heating control button 330. The temperature sensor continuously monitors the heating of the PTC plate, maintaining its temperature within the selected level. For example, the temperature levels can be set to three positions: 140°C, 160°C, and 220°C. During use, the user can adjust the temperature of the PTC plate according to needs.

[0058] As shown in Fig. 6, in the hair straightener presented in this embodiment of the utility model, the control unit 300 also comprises a Hall sensor 350 and a Hall switch 360, wherein the Hall sensor 350 is mounted on the lower housing 110, and the Hall switch 360 is fixed on the upper housing 210 in a corresponding position. The Hall switch 360 is electrically connected to the control panel 310 and the fan 130, thus forming a complete induction control circuit.

[0059] When the hair straightener is in the idle state, that is, when the upper clamping device 200 and the lower clamping device 100 are disconnected, there is no induced signal between the Hall switch 360 of the upper body 210 and the Hall sensor 350 of the lower body 110. In this case, the Hall switch 360 is in an open state even if the user presses the blower control button 320. Because the Hall switch 360 is not closed, the control panel 310 does not send a command to the fan 130, and the fan 130 does not start. This prevents the fan 130 from running idle when the hair straightener is not being used to clamp hair, which saves electricity and simultaneously reduces unnecessary noise.

[0060] When the user needs to clamp the hair for straightening with the hair straightener, he presses the fan control button 130 and rotates the upper clamping device 200 toward the lower clamping device 100. When the upper clamping device 200 rotates, the upper body 210 gradually approaches the lower body 110, when the Hall switch 360 of the upper body 210 and the Hall sensor 350 of the lower body 110 reach the working induction distance, an induced signal is generated between them, after which the Hall switch 360 is closed.After the Hall switch 360 is closed, a signal is transmitted to the control panel 310, having received the signal, the control panel 310 determines that the user is using the hair straightener to clamp the strands of hair, and sends a command to the fan 130 to start, the fan 130 starts to operate, sucks in air, which passes through the air guide channel 144 and comes out of the air outlet 112, together with the heating component, providing drying and straightening of the hair.

[0061] For example, during normal use, the user picks up the hair straightener and prepares to straighten hair. Until the hair is clamped between the upper and lower clamping devices 100, the fan 130 does not start. When the user places the hair between the upper clamping device 200 and the lower clamping device 100 and squeezes it, the Hall switch 360 detects a signal, and the fan 130 immediately starts, beginning normal operation. This Hall sensor-based control method allows the fan 130 to start when the hair is clamped and stop when the hair is not clamped, effectively improving the energy efficiency of the hair straightener, reducing operating costs, and simultaneously improving user convenience.

[0062] According to Fig. 1-3, in the hair straightener presented in this example of the embodiment of the utility model, the lower clamping device 100 further includes teeth 150, wherein the teeth 150 are mounted on the lower housing 110 in a removable manner and are located on one side of the lower heating component 120. During operation, the user can independently decide whether to install the teeth 150, depending on their habits and actual needs. For example, users with less hair volume and smoother hair can do without installing the teeth 150, since hair straightening is performed effectively without them; in this case, the teeth 150 can be removed, which reduces the overall weight of the straightener and makes its use more convenient, and for users with thick hair prone to tangling, the installation of the teeth 150 provides additional combing and facilitates the straightening process.

[0063] Furthermore, with prolonged use, the 150 teeth may become worn or damaged, or the user may want to replace them with 150 teeth of a different size or material to suit different hairstyles. The detachable design allows for a simple and quick replacement process. The user simply needs to perform a few disassembly steps, such as twisting or pulling out the 150 teeth, to easily remove the old ones and install the new 150 teeth.

[0064] During operation of the hair straightener, when the hair is clamped between the upper and lower clamping devices 100, the teeth 150 pre-comb the hair, ensuring it is guided evenly and smoothly into the heating zone. Thus, as the hair passes through the lower heating element 120 and the upper heating element 220, it is uniformly heated, preventing localized overheating or insufficient straightening caused by tangled or curled hair.

[0065] According to Fig. 1-3, in the hair straightener shown in this embodiment of the utility model, the lower housing 110 is equipped with an insertion groove 113 located in the longitudinal direction, the lower end of the teeth 150 has an insertion plate 151, the dimensions and shape of the insertion groove 113 correspond to the insertion plate 151 located at the lower end of the teeth 150, which ensures their precise and reliable connection. The size, thickness and shape of the edges of the insertion plate 151 correspond to the insertion groove 113, which ensures smooth insertion of the insertion plate 151 into the insertion groove 113 without play or loosening.

[0066] When installing the teeth 150, the user simply needs to align the insertion plate 151 at the lower end of the teeth 150 with the insertion groove 113 on the lower body 110, and then smoothly insert it in the longitudinal direction of the insertion groove 113. During the insertion process, the insertion plate 151 fits tightly against the inner wall of the insertion groove 113, and due to the friction between them and the precise match of the shape, the insertion plate 151 is securely fixed inside the insertion groove 113. This insertion method is simple and convenient, does not require the use of additional tools, and even a user who uses a hair straightener for the first time can easily install the teeth 150.

[0067] When it is necessary to remove the teeth 150, the user only needs to carefully remove the insert plate 151 from the insert groove 113 by moving it in the direction opposite to the direction of insertion.

[0068] According to Fig. 1 and 5, in the hair straightener shown in this embodiment of the utility model, when the air outlet 112 is located in the lower housing 110, the upper housing 210 is equipped with an exhaust outlet 211, and the exhaust outlet 211 wraps around the upper heating component 220; and vice versa, if the air outlet 112 is located in the upper housing 210, then the lower housing 110 has an exhaust outlet 211, and the exhaust outlet 211 goes around the lower heating component 120. As an example, when the air outlet 112 is located in the lower housing 110, the upper housing 210 is equipped with an exhaust outlet 211, and the exhaust outlet 211 goes around the upper heating component 220 and is in connection with the air outlet 112 of the hair straightener. This allows the air coming out of the air outlet 112 of the lower housing 110 to pass unhindered through the exhaust outlet 211 and be discharged outside.

[0069] When the hair straightener starts to work, the fan 130 sucks in air from the outside, creating a flow that is discharged through the air outlet 112 of the lower housing 110. Since the exhaust outlet 211 wraps around the upper heating component 220 and is in connection with the air outlet 112, part of the air when discharged directly acts on the hair clamped between the upper and lower clamping devices 100; and the other part of the air is discharged outside the hair straightener through the exhaust outlet 211, ensuring normal air flow.

[0070] The utility model is not limited to the above-mentioned methods of implementation; specialists in this technical field may make equivalent modifications or replace individual elements without violating the essence of this utility model; all such equivalent modifications and replacements are included in the scope of protection determined by the claims of this application.
