[0002] In the hairdressing industry, hair straighteners are a commonly used hairdressing tool that is widely used to straighten and style hair. Most traditional hair straighteners heat the hair through a heating element to make it smooth and easy to straighten. However, during the heating process, the hair is easily damaged by high temperatures and lacks a lasting styling effect after straightening.

[0003] In order to overcome these shortcomings, hair straighteners with cold air styling functions have gradually appeared on the market. After heating the hair, this type of hair straightener quickly cools the hair with cold air to achieve a styling effect. However, existing cold air hair straighteners still have some design deficiencies. For example, the cold air is not evenly distributed, resulting in poor styling effects, and the cold air generating device has large noise and vibration, which affects the user experience. Summary of the invention

[0004] In order to overcome the shortcomings and deficiencies in the prior art, an object of the present invention is to provide a cold air hair straightener.

[0005] To achieve the above-mentioned purpose, a cold air hair straightener of the present invention comprises a main body, the main body is provided with an ironing plate heating assembly, the main body comprises a first shell, a first cover body covered on the first shell, and a flow guide assembly located between the first shell and the first cover body; the first shell and the first cover body are covered to form a accommodating chamber, the flow guide assembly comprises a flow guide member arranged in the accommodating chamber, an air guide plate arranged on the first shell, an air containing cavity is formed between the air guide plate and the first shell, the flow guide member is used to accommodate a blowing assembly, the flow guide member is connected with the air containing cavity to form a first air duct, and a first air outlet hole connected with the air containing cavity is further provided on the first shell; the blowing assembly inhales fluid from the outside, flows along the first air duct, is diverted by the air guide plate, and is quickly discharged from the first air outlet hole to form cold air, and the cold air is used to style the hair heated by the ironing plate heating assembly.

[0006] Through the carefully designed guide component, including the guide member located in the accommodating chamber and the air guide plate on the first shell, the first air duct for the flow of cold air is effectively constructed, so that the cold air generated by the blowing component can flow smoothly along this air duct, and achieve precise diversion through the air guide plate, and finally be evenly discharged to quickly cool and shape the heated hair. In specific implementation, the user only needs to place the hair on the ironing plate heating component to heat it, and then start the blowing component. The cold air will flow along the preset path and act on the hair, achieving fast and uniform cooling and shaping, which greatly improves the straight hair effect and convenience of use.

[0007] The cold air hair straightener also includes a clamping plate body rotatably matched with the main body, the ironing plate heating assembly is arranged on a side where the main body or / and the clamping plate body are close to each other, the main body or the clamping plate body is provided with a control assembly, and the control assembly is electrically connected to the blowing assembly and the ironing plate heating assembly; one end of the main body is a handle portion, and the end away from the handle portion is a clamping portion, the first cover body is detachably connected to the handle portion, the guide member is located between the handle portion and the first cover body, the ironing plate heating assembly is arranged on the clamping portion, and the air guide plate is located between the ironing plate heating assembly and the first shell.

[0008] A rotatable clamping plate body and a control component are added to the main body, so that the ironing plate heating component and the blowing component can work together, and the user can easily adjust them through the control component. At the same time, the detachable connection between the first cover body and the handle part is convenient for maintenance and cleaning. The guide member is located between the handle part and the first cover body, which effectively utilizes the space and ensures the smooth flow of cold air. The ironing plate heating component is located in the clamping part, which is convenient for direct contact and heating of the hair, and the air guide plate is cleverly placed between the ironing plate heating component and the first shell body to guide the cold air to be evenly distributed. In specific implementation, the user can hold the handle part, clamp the hair with the clamping part, start the ironing plate heating component for heating through the control component, and then start the blowing component. The cold air is evenly blown on the heated hair through the action of the guide member and the air guide plate, so as to achieve rapid styling, simple operation and significant effect.

[0009] The air guide plate includes a first plate body arranged on the ironing plate heating assembly, and an air guide unit arranged on the first plate body, the air guide unit has an air guide strip, the air guide strip includes an air guide rib arranged along the length direction of the first plate body, and an arc-shaped air guide tail wing bent from the air guide rib along the width direction of the first plate body; the air guide rib is used to guide part of the cold air to flow along the length direction of the first plate body for secondary diversion of the cold air, and the arc-shaped air guide tail wing is used to gather part of the cold air.

[0010] The air guide plate includes a first plate body arranged on the ironing plate heating assembly, which serves as a supporting base and fixes the air guide strips. Multiple groups of air guide strips are arranged on the first plate body, and the layout and functional design of the air guide strips can effectively guide the flow of cold air to ensure that the cold air can accurately cover the hair. The air guide ribs are arranged along the length direction of the first plate body, and play a role in guiding part of the cold air to flow in this direction. In this way, the cold air can be diverted for a second time to ensure that the cold air can be evenly and accurately distributed when flowing through the hair, avoiding excessive concentration or unevenness of the wind flow. The far end of the air guide rib is provided with an arc-shaped air guide tail wing, which is arranged along the width direction of the first plate body, and can gather part of the cold air, helping the wind flow to act more concentratedly on the styling area of ​​the hair, thereby improving the styling effect of the cold air.

[0011] The air guide unit includes two air guide strips, the two air guide ribs of the two air guide strips are arranged in parallel, the air guide ribs of the two air guide strips are located between the arc-shaped air guide tail wings of the two air guide strips, the two air guide strips are arranged on the first plate body at intervals, and a second air duct is formed between the two air guide strips.

[0012] When the air guide unit includes two parallel air guide strips, the second air duct formed therebetween further promotes the uniform distribution and efficient use of cold air. In specific implementation, the user can start the ironing plate heating component and the blowing component through the control component. The cold air is guided and diverted through the air guide ribs under the joint action of the guide member and the air guide plate, and the wind direction and intensity are then adjusted by the arc-shaped air guide tail wing. Finally, it acts evenly and efficiently on the heated hair, achieving a fast and high-quality styling effect.

[0013] There are multiple groups of air guide units on the air guide plate, and the multiple groups of air guide units are arranged along the length direction of the air guide plate. The side close to the guide member is the first group of air guide units, and the side of the first group of air guide strips away from the guide member is the second group of air guide units. The width of the second air duct between the two air guide strips of the first group of air guide units is greater than the width of the second air duct between the two air guide strips of the second group of air guide units, and the second air duct of the first group of air guide units is connected to the second air duct of the second group of air guide units.

[0014] The width of the second air duct of the first group of air guide units (close to the guide member) is designed to be larger than the width of the second air duct of the second group of air guide units (far away from the guide member). This design not only ensures that the cold air can be fully diffused in the initial stage, but also enhances the flow rate and pressure of the cold air through the gradually narrowing air duct structure, thereby achieving precise focusing and efficient use of the cold air. The second air ducts of all air guide units are interconnected, ensuring the continuous flow and uniform distribution of the cold air on the entire air guide plate. In specific implementation, the user starts the ironing plate heating component and the blowing component, and the cold air enters the air guide plate under the guidance of the guide member. After being divided and focused step by step by multiple groups of air guide units, it finally acts on the heated hair with uniform and high-intensity cold air, achieving a fast and lasting styling effect, significantly improving the efficiency and user experience of the hair straightener.

[0015] A tail air guide group is also provided on the side of the second group of air guide units away from the first group of air guide units. The tail air guide group includes an air guide rib and two arc-shaped air guide tail wings arranged at the tail of the air guide rib. The tail air guide group is used to gather the cold air at the end of the second air duct. The air guide rib of the tail air guide group is located between the two air guide ribs of the second group of air guide units.

[0016] The single air guide rib and two curved air guide tail wings of the tail air guide group can efficiently gather the cold air at the end of the second air duct, ensuring the intensity and concentration of the cold air when it finally acts on the hair. The second air ducts of the entire air guide system are interconnected, ensuring the continuous, uniform and efficient flow of cold air throughout the entire flow channel.

[0017] A hollow boss is provided on one side of the air guide plate close to the guide member, and the air guide member includes a guide tube, a driving motor accommodated in the guide tube, fan blades arranged on the output shaft of the driving motor, and an electronic control device connected to the driving motor, and the driving motor, the fan blades and the electronic control device are combined to form a blowing assembly; the guide tube includes a cylinder body portion, and an air collecting portion used in conjunction with the hollow boss is provided at one end of the cylinder body portion, the hollow boss is accommodated in the air collecting portion, and the hollow boss is used to connect the air containing cavity and the cylinder body portion; the blowing assembly is located in the cylinder body portion.

[0018] The hollow boss designed on the side of the air guide plate close to the guide member perfectly cooperates with the air collecting part of the guide tube in the guide member, which not only simplifies the flow path of the cold air from the guide tube to the air chamber, but also enhances the initial speed and pressure of the cold air through the design of the air collecting part. The blower assembly integrated in the guide tube, including the drive motor, fan blades and electronic control devices, has a compact structure and excellent performance, ensuring the stable generation and continuous supply of cold air. In specific implementation, the user starts the ironing plate heating assembly and the blower assembly controlled by the electronic control device. The cold air is generated by the fan blade in the guide tube, and enters the air chamber through the guidance of the air collecting part and the hollow boss. After the step-by-step processing of multiple groups of air guide units and the final aggregation of the tail air guide group, the uniform and high-intensity cold air acts on the heated hair, achieving a fast, lasting and high-quality styling effect. This design not only significantly improves the use efficiency and styling quality of the hair straightener, but also reduces noise and energy consumption through structural optimization, greatly enhancing the user experience.

[0019] The guide tube also includes a hollow cone portion connecting the cylinder portion and the wind collecting portion. The inner hole diameter of the hollow cone portion gradually increases along the direction from the wind collecting portion to the cylinder portion. The cylinder portion is made of elastic material, and a plurality of groups of convex rings are arranged on the cylinder portion at intervals. The convex rings on the cylinder portion are in conflict with the inner wall of the first cover and / or the inner wall of the first shell to reduce the vibration and noise generated by the guide member during operation.

[0020] The guide tube in the guide member, especially its unique hollow cone design, not only optimizes the flow path of the cold air, but also effectively reduces the resistance and energy consumption of the cold air during the flow process by gradually increasing the inner hole diameter. At the same time, the barrel of the guide tube is made of elastic material, and multiple sets of convex rings are arranged at intervals. These convex rings conflict with the inner wall of the first cover and / or the inner wall of the first shell, which effectively reduces the vibration and noise generated by the guide member during operation and improves the overall stability and quietness of the hair straightener. The multiple sets of air guide units and the tail air guide group arranged on the air guide plate, combined with the gradually narrowing air duct structure, ensure that the entire process from the generation of cold air to the action on the hair remains efficient, uniform and concentrated.

[0021] Preferably, the guide tube is made of elastic material as a whole, that is, the cylinder part, the wind collecting part and the hollow cone part are formed in one piece, which can reduce the assembly of components, increase the overall sealing and facilitate flow diversion, and can be slightly stretched and deformed when assembled with other parts, reducing the difficulty of assembly requirements.

[0022] Because the temperature of the ironing plate heating component can reach up to 230 to 240 degrees Celsius when the product is working, when the distance between the air collecting part and the ironing plate heating component is set too short, the aging of the air collecting part will be accelerated and its performance will be affected. Therefore, when setting it, the air collecting part should be placed as close to the inner surface of the first shell as possible, and the ironing plate heating component of the main body should be placed away from the first shell to increase the distance between them.

[0023] Preferably, if Fig.11 As shown, the cross-sectional wind area B of the wind collecting part is smaller than the cross-sectional wind area A of the cylinder part, and 0.1A≤B≤0.2A, which can ensure that the wind flow through the wind collecting part can be accelerated when the blowing component is at a lower speed. Of course, the cross-sectional wind area B of the wind collecting part cannot be too small. If B<0.1A, the noise will increase and the air volume cannot meet the requirements of product design.

[0024] A boss ring is arranged outside the hollow boss, and the number of boss rings is multiple. The multiple boss rings are extended along the length direction of the hollow boss, and all boss rings of the hollow boss are located in the wind collecting part, and the wind collecting part is made of elastic material. The multiple boss rings arranged on the hollow boss strengthen the connection strength between the boss and the wind collecting part.

[0025] The first shell is provided with a plurality of recessed strip grooves extending along the length direction of the first shell, and a plurality of first air outlet holes are arranged at intervals in the strip grooves to prevent the hair wrapped around the main body from clogging the first air outlet holes; the air outlet holes are also arranged on both side longitudinal sides of the first shell to further increase the cold air straightening effect.

[0026] The design of the strip groove is coordinated with the interval of the first air outlet, which can effectively reduce the possibility of hair entering the first air outlet. The design of the groove makes the air flow more dispersed and is not easy to guide the hair directly into the hole, thereby avoiding the blockage problem. In this way, even if the hair approaches the air outlet during use, it is not easy to block the air outlet, thereby improving the reliability of the device.

[0027] The electric control device is connected to the control assembly via a power line. The power line passes through the puncture hole on the side of the guide tube or is directly led from the air collecting part to the control assembly. The power line passes through the puncture hole on the side of the guide tube, and sealant is applied at the puncture hole to prevent air leakage. This design is simple and compact. In this way, the isolation between the power line and other components (such as the cold air channel and the air guide plate) can be ensured to avoid interference between the power line and the cold air flow area. Another design is to directly lead the power line out of the air collecting part and connect it to the control assembly. The design of the lead wire of the air collecting part can optimize the wiring method and make the power line more concealed.

[0028] The side of the clamp body is provided with heat dissipation holes, and the heat dissipation holes are arranged along the length direction of the clamp body. The heat dissipation holes are arranged along the length direction of the clamp body, which can distribute the heat release more evenly. In this way, during the use of the cold air hair straightener, the heat will not be concentrated in a certain part, but can be evenly distributed and quickly dissipated to the outside through the heat dissipation holes, ensuring that the internal temperature of the device is kept within a reasonable range.

[0029] The control assembly includes a first electric control board and a second electric control board vertically mounted on the first electric control board. A mounting groove is provided on the bottom surface of the first electric control board, and a limiting protrusion is provided on the side of the second electric control board. The second electric control board is vertically mounted in the mounting groove of the first electric control board via the limiting protrusion. The first electric control board and the second electric control board are manufactured in a separate processing manner. If a certain electric control board in the electric control system fails, the damaged electric control board can be replaced separately without replacing the entire control assembly, thereby reducing maintenance costs and time. The vertical installation method saves installation space and enables the control assembly to be more compactly integrated in a limited space. This not only optimizes the overall structural design of the cold air hair straightener, but also makes the layout of internal parts more reasonable, thereby improving the space utilization rate of the equipment.

[0030] The hair straightener also includes an air inlet assembly installed at the end of the handheld part of the main body, the air inlet assembly includes a mounting ring, an air inlet net clamped with the mounting ring, the mounting ring is provided with a positioning limit groove and a clamping groove, a first protrusion and a second protrusion are provided on the inner wall of the annular air inlet net, the first protrusion is clamped with the positioning limit groove to prevent the air inlet net from moving left and right, and the second protrusion is clamped with the clamping groove to prevent the air inlet net from moving up and down.

[0031] The design of the air inlet net can effectively guide the air flow into the device, and the snap-on design prevents the air inlet net from moving, making the air flow direction more accurate and avoiding the deviation of the air flow direction. This can improve the efficiency of air inflow and enable the device to maintain a stable wind speed and wind force during operation. The air inlet net can be easily disassembled and cleaned through the snap-on design of the mounting ring and the air inlet net. Regular cleaning of the air inlet net can effectively prevent the accumulation of dust and impurities, maintain smooth air circulation inside the device, and also extend the service life of the device.

[0032] The first electric control board and the second electric control board are both arranged longitudinally along the accommodating chamber and are arranged between the air inlet component and the guide member. The external fluid flows in from the air inlet component and passes through the first electric control board and the second electric control board to take away the heat generated by the electronic components, thereby improving product performance and extending product life.

[0033] The second electric control panel is provided with a display screen, a switch and mode selection button, a temperature and wind speed increase button, and a temperature and wind speed decrease button. A groove is opened on the side of the first cover body, and a mounting shell is installed on the groove. The mounting shell is made of a light-transmitting material. The mounting shell is provided with a first through hole for accommodating the switch and mode selection button, the temperature and wind speed increase button, and the temperature and wind speed decrease button; the groove is provided with a second through hole corresponding to the first through hole of the mounting shell. The mounting shell is installed on the first cover body via the groove, and is used to protect the display screen and the buttons from external damage, while increasing the overall aesthetics of the hair straightener. The mounting shell is made of a light-transmitting material, such as transparent plastic or acrylic, so that light can penetrate and illuminate the display screen for users to check the temperature and wind speed.

[0034] This design effectively protects the display screen and buttons of the cold air hair straightener through the combination of the mounting shell and the groove made of translucent material, while improving the aesthetics and ease of use of the device. The translucent design not only enhances the visual effect of the device and creates a modern feel, but also allows light to penetrate and illuminate the display screen, making it easier for users to view information such as temperature and wind speed. The protective function effectively protects the device from external damage and improves durability. The simple installation and easy-to-clean design improve the user experience and further enhance the market competitiveness of the device.

[0035] Beneficial effects of the present invention: The cold air hair straightener provided by the present invention realizes efficient generation, stable flow and precise control of cold air through its innovative design of guide assembly and air guide plate. The guide member and the air guide plate in the guide assembly work together, which not only optimizes the flow path of the cold air and reduces energy consumption, but also ensures that the cold air is efficient, uniform and concentrated throughout the entire process from generation to action on the hair through the arrangement of multiple groups of air guide units and tail air guide groups. At the same time, the elastic material design and convex ring structure of the guide tube, as well as the elastic material and boss ring arrangement of the air collecting part, effectively reduce the vibration and noise during operation, and improve the overall stability and quiet performance of the hair straightener. In addition, the design of the strip groove and multiple first air outlets on the first shell prevents the problem of hair blocking the air outlet, further enhancing the user experience. This series of innovative designs not only significantly improves the use efficiency and styling quality of the hair straightener, but also greatly reduces noise and energy consumption, bringing users a more comfortable and efficient hair straightening experience.

The width of the second air duct 21 between the two air guide strips 17 of the first group of air guide units 102 is greater than the width of the second air duct 21 between the two air guide strips 17 of the second group of air guide units 102, and the second air duct 21 of the first group of air guide units 102 is connected to the second air duct 21 of the second group of air guide units 102.

[0048] The width of the second air duct 21 of the first group of air guide units 102 (close to the air guide 12) is designed to be greater than the width of the second air duct 21 of the second group of air guide units 102 (far away from the air guide 12). This design not only ensures that the cold air can be fully diffused in the initial stage, but also enhances the flow rate and pressure of the cold air through the gradually narrowing air duct structure, thereby achieving precise focusing and efficient use of the cold air. The second air ducts 21 of all air guide units 102 are interconnected, ensuring the continuous flow and uniform distribution of the cold air on the entire air guide plate 13. In specific implementation, the user starts the ironing plate heating component 3 and the blowing component 101, and the cold air enters the air guide plate 13 under the guidance of the air guide 12. After being divided and focused step by step by multiple groups of air guide units 102, the cold air finally acts on the heated hair with uniform and high-intensity cold air, achieving a fast and lasting styling effect, which significantly improves the efficiency and user experience of the hair straightener.

[0049] A tail air guide group 22 is also provided on the side of the second group of air guide units 102 away from the first group of air guide units 102. The tail air guide group 22 includes an air guide rib 18 and two arc-shaped air guide tail wings 19 arranged at the tail of the air guide rib 18. The tail air guide group 22 is used to gather the cold air at the end of the second air duct 21. The air guide rib 18 of the tail air guide group 22 is located between the two air guide ribs 18 of the second group of air guide units 102.

[0050] The single air guide rib 18 and two arc-shaped air guide tail wings 19 of the tail air guide group 22 efficiently gather the cold air at the end of the second air duct 21, ensuring the intensity and concentration of the cold air when it finally acts on the hair. The second air ducts 21 of the entire air guide system are interconnected, ensuring the continuous, uniform and efficient flow of the cold air in the entire flow channel.

[0051] A hollow boss 23 is provided on one side of the air guide plate 13 close to the air guide member 12. The air guide member 12 includes a air guide tube 24, a driving motor 25 accommodated in the air guide tube 24, a fan blade 104 arranged on an output shaft 103 of the driving motor 25, and an electronic control device 26 connected to the driving motor 25. The driving motor 25, the fan blade 104, and the electronic control device 26 are combined to form a blowing assembly 101; the air guide tube 24 includes a barrel portion 27, one end of the barrel portion 27 is provided with an air collecting portion 28 used in conjunction with the hollow boss 23, the hollow boss 23 is accommodated in the air collecting portion 28, and the hollow boss 23 is used to connect the air containing cavity 100 with the barrel portion 27; the blowing assembly 101 is located in the barrel portion 27.

[0052] The hollow boss 23 designed on one side of the air guide plate 13 close to the air guide member 12 perfectly matches the air collecting portion 28 of the air guide tube 24 in the air guide member 12, which not only simplifies the flow path of the cold air from the air guide tube 24 to the air containing cavity 100, but also enhances the initial speed and pressure of the cold air through the design of the air collecting portion 28. The blowing assembly 101 integrated in the air guide tube 24, including the driving motor 25, the fan blades 104 and the electronic control device 26, has a compact structure and excellent performance, ensuring the stable generation and continuous supply of cold air. In specific implementation, the user starts the ironing plate heating component 3 and the blowing component 101 controlled by the electronic control device 26, and the cold air is generated by the fan blades 104 in the guide tube 24, and enters the air-containing cavity 100 through the guidance of the air collecting portion 28 and the hollow boss 23, and then is processed step by step by multiple groups of air guide units 102 and finally gathered by the tail air guide group 22, so that the uniform and high-intensity cold air acts on the heated hair, achieving a fast, lasting and high-quality styling effect. This design not only significantly improves the use efficiency and styling quality of the hair straightener, but also reduces noise and energy consumption through structural optimization, greatly enhancing the user experience.

[0053] The guide tube 24 also includes a hollow cone 105 connecting the cylinder portion 27 and the wind collecting portion 28. The inner hole diameter of the hollow cone 105 gradually increases along the direction from the wind collecting portion 28 to the cylinder portion 27. The cylinder portion 27 is made of elastic material, and a plurality of groups of convex rings 32 are arranged on the cylinder portion 27 at intervals. The convex rings 32 on the cylinder portion 27 are in contact with the inner wall of the first cover body 5 and / or the inner wall of the first shell body 4 to reduce the vibration and noise generated by the guide member 12 during operation.

[0054] The guide tube 24 in the guide member 12, especially its unique hollow cone 105 design, not only optimizes the flow path of the cold air, but also effectively reduces the resistance and energy consumption of the cold air during the flow process by gradually increasing the inner hole diameter. At the same time, the barrel portion 27 of the guide tube 24 is made of elastic material, and multiple groups of convex rings 32 are arranged at intervals. These convex rings 32 conflict with the inner wall of the first cover body 5 or / and the inner wall of the first shell 4, effectively reducing the vibration and noise generated by the guide member 12 during operation, and improving the overall stability and quiet performance of the hair straightener. The multiple groups of air guide units 102 and the tail air guide group 22 arranged on the air guide plate 13, combined with the gradually narrowing air duct structure, ensure that the entire process from the generation of cold air to the action on the hair remains efficient, uniform and concentrated.

[0055] Preferably, the guide tube 24 is made of elastic material in one piece, that is, the cylinder portion 27, the air collecting portion 28, and the hollow cone portion 105 are formed in one piece, which can reduce the assembly of components, increase the overall sealing and facilitate flow diversion, and can be slightly stretched and deformed when assembled with other components, reducing the difficulty of assembly requirements.

[0056] When the product is working, the temperature of the ironing plate heating component 3 can reach up to 230 to 240 degrees Celsius. When the distance between the air collecting part 28 and the ironing plate heating component 3 is set too short, the aging of the air collecting part 28 will be accelerated and its performance will be affected. Therefore, when setting, the air collecting part 28 should be as close to the inner surface of the first shell 4 as possible, and the ironing plate heating component 3 of the main body 1 should be away from the first shell 4 to increase the distance between them.

[0057] Preferably, if Fig.11 As shown, the cross-sectional wind area B of the wind collecting portion 28 is smaller than the cross-sectional wind area A of the cylindrical portion 27, and 0.1A≤B≤0.2A, which can ensure that the wind flow through the wind collecting portion 28 can be accelerated at a lower rotation speed of the blowing component 101. Of course, the cross-sectional wind area B of the wind collecting portion 28 cannot be too small. If B<0.1A, the noise will increase and the air volume cannot meet the requirements of product design.

[0058] A boss ring 106 is provided on the outer side of the hollow boss 23. The number of boss rings 106 is multiple, and the multiple boss rings 106 are extended along the length direction of the hollow boss 23. All boss rings 106 of the hollow boss 23 are located at the wind collecting portion 28, and the wind collecting portion 28 is made of elastic material. The multiple boss rings 106 provided on the hollow boss 23 strengthen the connection strength between the boss and the wind collecting portion 28.

[0059] The first shell 4 is provided with a plurality of recessed strip grooves 33, which extend along the length direction of the first shell 4. A plurality of first air outlet holes 15 are arranged at intervals in the strip grooves 33, which can prevent the hair that comes up from the main body 1 from clogging the first air outlet holes 15; the air outlet holes 15 are also arranged on both side longitudinal sides of the first shell 4, further increasing the cold air straightening effect.

[0060] The design of the strip groove 33 cooperates with the first air outlet 15 to effectively reduce the possibility of hair entering the first air outlet 15. The design of the groove makes the air flow more dispersed and does not easily guide the hair directly into the hole, thereby avoiding the problem of blockage. In this way, even if hair approaches the air outlet during use, it is not easy to block the air outlet, thereby improving the reliability of the device.

[0061] The electric control device 26 is connected to the control assembly 7 via a power line. The power line passes through the puncture hole on the side of the guide tube 24 or is directly led from the air collecting part 28 to the control assembly 7. The power line passes through the puncture hole on the side of the guide tube 24, and sealant is applied at the puncture hole to prevent air leakage. This design is simple and compact. In this way, the isolation between the power line and other components (such as the cold air channel and the air guide plate 13) can be ensured to avoid interference between the power line and the cold air flow area. Another design is to directly lead the power line out of the air collecting part 28 and connect it to the control assembly 7. The design of the lead of the air collecting part 28 can optimize the wiring method and make the power line more concealed.

[0062] The side of the clamp body 2 is provided with heat dissipation holes 70, and the heat dissipation holes 70 are arranged along the length direction of the clamp body 2. The heat dissipation holes 70 are arranged along the length direction of the clamp body 2, which can distribute the release of heat more evenly. In this way, during the use of the cold air hair straightener, the heat will not be concentrated in a certain part, but can be evenly distributed and quickly dissipated to the outside through the heat dissipation holes 70, ensuring that the internal temperature of the device is kept within a reasonable range.

[0063] The control assembly 7 includes a first electric control board 52 and a second electric control board 53 vertically mounted on the first electric control board 52. A mounting groove 54 is provided on the bottom surface of the first electric control board 52, and a limiting protrusion 55 is provided on the side of the second electric control board 53. The second electric control board 53 is vertically mounted in the mounting groove 54 of the first electric control board 52 via the limiting protrusion 55. The first electric control board 52 and the second electric control board 53 are manufactured in a separate processing manner. If a certain electric control board in the electric control system fails, the damaged electric control board can be replaced separately without replacing the entire control assembly 7, thereby reducing maintenance costs and time. The vertical installation method saves installation space, so that the control assembly 7 can be more compactly integrated in a limited space. This not only optimizes the overall structural design of the cold air hair straightener, but also makes the arrangement of internal parts more reasonable, thereby improving the space utilization rate of the equipment.

[0064] The hair straightener also includes an air inlet assembly 56 installed at the end of the handheld portion of the main body 1. The air inlet assembly 56 includes a mounting ring 57 and an air inlet net 58 clamped with the mounting ring 57. The mounting ring 57 is provided with a positioning limit groove 59 and a clamping groove 60. A first protrusion 61 and a second protrusion 62 are provided on the inner wall of the annular air inlet net 58. The first protrusion 61 is clamped with the positioning limit groove 59 to prevent the air inlet net 58 from moving left and right, and the second protrusion 62 is clamped with the clamping groove 60 to prevent the air inlet net 58 from moving up and down.

[0065] The first electric control board 52 and the second electric control board 53 are both arranged longitudinally along the accommodating chamber 8 and are arranged between the air inlet component 56 and the guide member 12. The external fluid flows in from the air inlet component 56 and passes through the first electric control board 52 and the second electric control board 53 to take away the heat generated by the electronic components, thereby improving product performance and extending the life of the product.

[0066] The design of the air inlet net 58 can effectively guide the air to flow into the device, and because the snap-fit ​​design prevents the air inlet net 58 from moving, the air flow direction is more accurate and the deviation of the air flow direction is avoided. This can improve the efficiency of air inflow and enable the device to maintain a stable wind speed and wind force during operation. Through the snap-fit ​​design of the mounting ring 57 and the air inlet net 58, the air inlet net 58 can be easily disassembled and cleaned. Regular cleaning of the air inlet net 58 can effectively prevent the accumulation of dust and impurities, maintain smooth air circulation inside the device, and also extend the service life of the device.

[0067] The second electric control panel 53 is provided with a display screen 63, a switch and mode selection button 64, a temperature and wind speed increase button 65, and a temperature and wind speed decrease button 66. A groove 67 and a mounting shell 68 mounted on the groove 67 are provided on the side of the first cover body 5. The mounting shell 68 is made of a light-transmitting material. A first through hole 72 for accommodating the switch and mode selection button 64, the temperature and wind speed increase button 65, and the temperature and wind speed decrease button 66 is provided on the mounting shell 68; a second through hole 73 corresponding to the first through hole 72 of the mounting shell 68 is provided on the groove 67. The mounting shell 68 is installed on the first cover body 5 via the groove 67 to protect the display screen 63 and the buttons from external damage and to increase the overall aesthetics of the hair straightener. The mounting shell 68 is made of a light-transmitting material, such as transparent plastic or acrylic, so that light can penetrate and illuminate the display screen 63 for users to check the temperature and wind speed.

[0068] This design effectively protects the display screen 63 and buttons of the cold air hair straightener through the cooperation of the mounting shell 68 and the groove 67 made of translucent material, while improving the aesthetics and ease of use of the device. The translucent design not only enhances the visual effect of the device and creates a modern feel, but also allows light to penetrate and illuminate the display screen 63, making it easier for users to view information such as temperature and wind speed. The protective function effectively protects the device from external damage and improves durability. The simple installation and easy-to-clean design enhance the user experience and further enhance the market competitiveness of the device.
