Some innovative straightening irons integrating the functions of blowing, perming and cold wind styling have gradually appeared on the market. These devices can heat the hair while styling by cold wind through the combination of blowing unit and perming unit, thereby avoiding the damage of overheat to the hair. However, the flow guide structure in the prior art still has problems such as uneven airflow, excessive vibration and unstable structure, which affects the efficiency and stability of the device. SUMMARY

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the utility model is to provide a shock absorption flow guide structure and straightening iron with shock absorption flow guide structure.

[0004] To achieve the above-mentioned purpose, the utility model relates to a shock absorption flow guide structure, which comprises a shock absorption flow guide member, the shock absorption flow guide member is integrally formed by an elastic material, and comprises a cylindrical part and a wind collecting part; the cylindrical part is used for fixing and limiting a blowing unit; the shock absorption flow guide structure further comprises a hollow taper part which is in communication with the cylindrical part and the wind collecting part, the inner hole diameter of the hollow taper part gradually increases in the direction from the wind collecting part to the cylindrical part; the cross-sectional wind passing area B of the wind collecting part is smaller than the cross-sectional wind passing area A of the cylindrical part, and satisfies 0.1A≤B≤0.2A; the wind collecting part and the cylindrical part are arranged in unilateral alignment; a plurality of shock absorption protrusions are arranged on the outer surface of the cylindrical part in intervals.

[0005] A straightening iron comprises a first clamping plate, a second clamping plate and an elastic member, one end of the first clamping plate and the second clamping plate are hinged, and the other end can be opened and closed to receive and clamp hair; the elastic recovery force of the elastic member is used to keep the two clamping plates in an open state or a closed state; the first clamping plate or the second clamping plate comprises a shell member, a blowing unit, a cover plate member, a perming unit and a shock absorption flow guide member, two ends of the shell member are a handle part and a perming part respectively, the cover plate member is detachably connected with the handle part, the shock absorption flow guide member is located between the handle part and the cover plate member, the shock absorption flow guide member is sleeved on the outside of the blowing unit, the perming unit is arranged in the perming part, and the two perming units are located on the side of the two clamping plates close to each other; the perming part is provided with an air outlet hole in communication with the shock absorption flow guide member.

[0006] The first clamping plate and the second clamping plate are conveniently opened and closed through rotation and elastic restoring force of the elastic member; meanwhile, the integrated design of the blowing unit, the hair straightening unit and the shock-absorbing flow guide improves the straightening efficiency, optimizes the airflow path through the shock-absorbing flow guide, reduces vibration, ensures smooth air outlet, realizes the dual functions of rapid drying and straightening, and the detachable design of the cover plate facilitates maintenance and cleaning.

[0007] The straightening device is also provided with an air guide plate on the housing member, and an air chamber is formed between the air guide plate and the housing member. The shock-absorbing flow guide is in communication with the air chamber to form a first air duct. The external fluid sucked by the blowing unit flows along the first air duct, is divided by the air guide plate, and is quickly discharged from the air outlet hole to form cold air. The cold air quickly cools and shapes the hair heated by the hair straightening unit.

[0008] When the blowing unit and the shock-absorbing flow guide are arranged on the second clamping plate, the air outlet hole is arranged on the bottom surface and the side edge of the housing member of the second clamping plate along the length direction of the housing member, which ensures smooth air outlet of the blowing unit.

[0009] The straightening device optimizes the airflow channel by arranging the air guide plate on the housing member and using the air chamber formed between the air guide plate and the housing member. The shock-absorbing flow guide is in communication with the air chamber to form a first air duct. The cold air blown by the blowing unit flows through the first air duct and is divided by the air guide plate, and is uniformly discharged from the air outlet hole. The cold air not only helps to alleviate the damage of heat to the hair, but also helps the hair to cool and shape quickly after being heated by the hair straightening unit, providing a more smooth and natural effect. At the same time, this design enhances the stability and comfort of the product, ensuring efficient drying and shaping functions.

[0010] The hollow ring-shaped table is arranged on one side of the air guide plate close to the shock-absorbing flow guide, and is used in cooperation with the air collecting part of the shock-absorbing flow guide to optimize the guiding and dividing effect of the airflow. The hollow ring-shaped table communicates the air chamber with the cylindrical part to ensure that the cold air generated by the blowing unit can flow efficiently and form a smooth airflow path through the air collecting part and the hollow cone part. The gradually increasing design of the inner hole of the hollow cone part helps to guide the airflow to be more uniformly distributed, avoiding the blockage of the airflow. At the same time, the cylindrical part, as a part of the shock-absorbing flow guide, is made of elastic material and is provided with multiple shock-absorbing protrusions. These shock-absorbing protrusions are in contact with the inner wall of the cover plate or the housing member, further reducing the vibration and noise generated during use, improving the comfort experience of the user, and enhancing the stability and durability of the equipment.

[0011] The hollow annular table is provided with a plurality of boss rings extending along the length direction of the hollow annular table. All the boss rings of the hollow annular table are inserted into the wind collecting part in an interference fit. The wind collecting part, as a part of the shock-absorbing flow guide, is made of elastic material. The connection between the parts is stable and the sealing performance is good, which can ensure smooth flow of fluid.

[0012] The plurality of boss rings can provide additional support to prevent displacement or loosening during use. All the boss rings are located inside the wind collecting part and abut against the inner side wall of the wind collecting part. The wind collecting part is made of elastic material, which can adapt to different working environments and effectively resist external pressure, further improving the tightness and durability of the structure. This design optimizes the guidance and control of airflow, reduces noise caused by vibration and friction, and improves the stability and comfort of the straightening iron during use.

[0013] The first clamping plate is provided with an opening and closing guide rail slot, and the second clamping plate is provided with an opening and closing lock. The opening and closing lock includes an opening and closing guide rail slider and a sliding member. The opening and closing guide rail slot is coveringly arranged on the opening and closing lock to form a sliding chamber. The sliding member is slidingly arranged in the sliding chamber. The opening and closing guide rail slider is further provided with a limiting portion. The sliding member is slid to the end away from the limiting portion, and the elastic member is released. The first clamping plate and the second clamping plate are in an open state. When an external force is applied to keep the first clamping plate and the second clamping plate closed, the sliding member is slid to the end close to the limiting portion, and the sliding member is limited in the limiting portion. The elastic member is compressed. The cooperation between the sliding member and the limiting portion enables the first clamping plate and the second clamping plate to remain in a closed state after the external force is released.

[0014] The opening and closing lock includes an opening and closing guide rail slider and a sliding member. The sliding member can freely slide in the sliding chamber. When the sliding member slides away from the limiting portion, the sliding member is released, thereby relaxing the elastic member and keeping the first clamping plate and the second clamping plate in an open state. When an external force is applied to keep the first clamping plate and the second clamping plate closed, the sliding member slides towards the limiting portion. The sliding member is limited in the limiting portion. The cooperation between the sliding member and the limiting portion enables the first clamping plate and the second clamping plate to remain in a closed state after the external force is released.

[0015] The opening and closing guide rail slot is provided with a first protrusion, and the opening and closing lock is provided with a second protrusion. One end of the elastic member is installed on the first protrusion, and the other end is installed on the second protrusion.

[0016] The design of the first protrusion and the second protrusion not only improves the stability of the elastic member, but also effectively avoids excessive stretching or compression of the elastic member, enhancing the durability and reliability of the structure and ensuring that the clamping plate can be accurately in an open or closed state.

[0017] The sliding member comprises a locking slider and a locking cover, the locking slider is provided with a mounting groove, the opening-closing guide rail sliding groove bottom is provided with a slot, the locking cover comprises a sliding part slidingly arranged on the first clamping plate body and a sliding rod arranged on the sliding part, the locking cover is arranged in the mounting groove through the slot via the sliding rod, and the sliding rod drives the locking slider to reciprocate in the sliding chamber after the sliding part is slid.

[0018] The side of the locking slider close to the limiting part is provided with a lock, when the first clamping plate and the second clamping plate are kept in a closed state by applying an external force, the locking cover drives the locking slider to slide to the side close to the limiting part, and the lock is limited in the limiting part, so that the first clamping plate and the second clamping plate can still be kept in a closed state after the external force is released.

[0019] The function of the lock is to accurately limit the locking slider in the limiting part, so that the slider cannot deviate or be misoperated during the opening and closing process of the sliding member, when the locking slider is close to the limiting part, the lock enters the limiting part, so that the slider cannot continue to slide, thereby keeping the first clamping plate and the second clamping plate in a closed state. Conversely, when the sliding member is away from the limiting part, the lock is released, and the first clamping plate and the second clamping plate recover to an open state under the elastic force of the elastic member. This design effectively prevents unstable movement of the locking slider, improves the safety, reliability and accuracy of the opening and closing mechanism, and ensures smooth operation and service life of the device.

[0020] The side of the locking slider is also provided with an elastic limiting arm, the side of the elastic limiting arm is provided with a protruding part, and the protruding part is used for abutting against the inner side wall of the opening-closing guide rail sliding block to prevent the locking slider from falling off.

[0021] By arranging the elastic limiting arm on the side of the locking slider and the protruding part on the side of the limiting arm, the locking slider can be effectively prevented from falling off or deviating during the opening and closing process. The function of the elastic limiting arm is to provide a certain elastic resistance force, so that the locking slider can always be kept in the correct position. When the locking slider moves in the sliding chamber, the protruding part will contact the inner side wall of the opening-closing guide rail sliding block, so as to avoid falling off or unstable movement of the slider.

[0022] Preferably, the cross-wind area B of the wind collecting part is smaller than the cross-wind area A of the cylindrical part, and 0.1A≤B≤0.2A, so that the wind flow passing through the wind collecting part can be accelerated at a low rotating speed of the blowing unit. Of course, the cross-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 product design requirements.

[0023] Since the temperature of the hair iron unit can reach 230-240 degrees Celsius when the product is in operation, setting the air collecting part too close to the hair iron unit can accelerate the aging of the air collecting part and affect its performance. Therefore, the air collecting part is arranged as close as possible to the inner surface of the housing member, and the hair iron unit is arranged away from the housing member to increase the distance between them. Specifically, the air collecting part and the cylindrical part are arranged in a non-concentric shaft arrangement, i.e., the air collecting part and the cylindrical part are arranged in a one-sided alignment arrangement.

[0024] The convex part is in a semi-spherical structure. The design of the semi-spherical convex part not only prevents the sliding part from falling off, but also increases the contact area between the sliding part and the opening and closing guide rail slider, enhancing the stability of the connection.

[0025] The hair iron unit on one side of the first clamping plate and the second clamping plate is provided with a buffer, and the inner bottom surface of the housing member is provided with a receiving groove. The buffer is installed in the receiving groove. The buffer is used to reduce the speed and temperature of heat transfer from the hair iron unit to the housing member, so as to keep the temperature of the housing member within a safe range. The buffer can also realize the floating function of the two opposite hair iron units when clamping hair.

[0026] The air guide plate includes a first plate body arranged on the hair iron unit and an air guide unit arranged on the first plate body. The air guide unit has an air guide strip, which includes an air guide rib arranged along the length direction of the first plate body and an arc-shaped tail wing arranged 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 distribution of the cold air. The arc-shaped tail wing is used to gather part of the cold air to change the direction of the air flow.

[0027] The air guide plate includes a first plate body arranged on the hair iron heating assembly as a support base and a fixed air guide strip. Multiple groups of air guide strips are arranged on the first plate body. The layout and functional design of the air guide strips can effectively guide the flow of cold air and ensure that the cold air can accurately cover the hair. The air guide rib is arranged along the length direction of the first plate body, which plays a role in guiding part of the cold air to flow in this direction. In this way, the cold air can be distributed in a secondary distribution manner to ensure that the cold air can be evenly and accurately distributed when flowing through the hair, avoiding excessive concentration or unevenness of the air flow. The distal end of the air guide rib is provided with arc-shaped tail wings, which are arranged along the width direction of the first plate body. These tail wings can gather part of the cold air to help the air flow more concentratedly act on the styling area of the hair, thereby improving the styling effect of the cold air.

[0028] The hair straightener also includes a control assembly electrically connected with the hair iron unit and the air blowing unit. The control assembly drives the hair iron unit to heat and straighten external hair. After the control assembly drives the air blowing unit to suck in cold air from the outside and flow to the hair iron part through the shock-absorbing guide part, the cold air is discharged through the air outlet hole to quickly cool and style the external hair.

[0029] The air guide unit comprises two air guide strips, 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 tail wings of the two air guide strips, the two air guide strips are arranged on the first plate body in a spaced manner, and the second air duct is formed between the two air guide strips.

[0030] When the air guide unit comprises two air guide strips arranged in parallel, the second air duct formed between the two air guide strips further promotes the uniform distribution and efficient use of cold air. In specific implementation, the user can start the ironing plate heating assembly and the blowing assembly through the control assembly. Under the joint action of the flow guide and the air guide plate, the cold air is guided and divided by the air guide ribs, and then the wind direction and intensity are adjusted by the arc-shaped tail wings. Finally, the cold air uniformly and efficiently acts on the heated hair, realizing a rapid and high-quality cooling and styling effect.

[0031] The number of air guide units on the air guide plate is multiple groups, the multiple groups of air guide units are arranged along the length direction of the air guide plate, the side close to the flow guide is the first group of air guide units, the side away from the flow guide of the first group of air guide strips is the second group of air guide units, the width of the second air duct spaced between the two air guide strips of the first group of air guide units is greater than the width of the second air duct spaced 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 and the second air duct of the second group of air guide units are communicated.

[0032] The second air duct width of the first group of air guide units (close to the flow guide) is designed to be greater than the second air duct width of the second group of air guide units (away from the flow guide). 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, realizing precise focusing and efficient use of the cold air. The second air ducts of all air guide units are communicated with each other, 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 assembly and the blowing assembly. The cold air enters the air guide plate under the guidance of the flow guide, is gradually divided and focused by the multiple groups of air guide units, and finally acts on the heated hair with uniform and high-intensity cold air, realizing a rapid and long-lasting styling effect, and significantly improving the use efficiency and user experience of the straightening iron.

[0033] The side away from the first group of air guide units of the second group of air guide units is further provided with a terminal air guide group. The terminal air guide group comprises one air guide rib and two arc-shaped tail wings arranged at the tail of the air guide rib. The terminal air guide group is used for gathering the cold air at the end of the second air duct. The air guide rib of the terminal air guide group is located between the two air guide ribs of the second group of air guide units.

[0034] The single air guide rib of the terminal air guide group and the two arc-shaped tail wings are arranged to efficiently gather the cold air at the end of the second air duct, and ensure the intensity and concentration of the cold air when the cold air finally acts on the hair.

[0035] When the blowing unit and the shock-absorbing guide member are arranged on the second clamping plate body, the outer side of the first clamping plate is provided with heat dissipation holes, and the heat dissipation holes on the first clamping plate are used to dissipate the heat generated by the hair straightening unit, so as to avoid that the temperature inside and on the surface of the shell member of the first clamping plate is too high.

[0036] Since the first clamping plate and the second clamping plate are hingedly connected at one end and opened and closed at the other end, both are in a long and narrow shape, and tend to be left and right offset when the other end is closed, so that the two hair straightening units are difficult to align and fit. In order to solve this problem or reduce the impact, a sliding limiting cavity is recessed on the cover plate member, and a second cover plate member is arranged on the first clamping plate in correspondence, the second cover plate member is protrusively arranged downward with a sliding first wall, the sliding first wall slides in the sliding limiting cavity, the sliding first wall forms an opening and closing guide rail sliding groove, the outer wall of the sliding cavity is protrusively arranged upward to form a sliding second wall, the sliding second wall slides in the opening and closing guide rail sliding groove, the top of the sliding second wall extends into the sliding cavity to form a limiting portion, and when the product is closed, the limiting portion blocks or approaches the bottom of the opening and closing guide rail sliding groove. Therefore, the locking block structure can be more compact, and such a structure design not only solves or reduces the problem of left and right offset when the upper and lower clamping plates are closed, but also simplifies the locking structure.

[0037] The utility model discloses the beneficial effects: the utility model discloses through the integration blowing unit, hair straightening unit and the innovative shock-absorbing guide member, not only significantly improved straightening efficiency, also optimized airflow path, effectively reduced vibration and noise, ensured the smooth and uniform of the air outlet. The cross-sectional wind area B of the shock-absorbing guide member set wind part is less than the cross-sectional wind area A of the cylinder part, and 0.1A≤B≤0.2A, which can ensure that the blowing unit can still accelerate the airflow through the set wind part at a lower speed, and ensure that the straightening efficiency is not affected.

[0038] At the same time, the air guide plate and the plurality of air guide units used by the hair straightener further enhance the focusing and efficient use of cold air, achieve rapid cooling and shaping, and improve the user experience. In addition, the unique opening and closing locking and heat dissipation design solves the problem of closing offset, ensures the stability and durability of the product, and provides users with a safer, more comfortable and efficient straightening experience.

DETAILED DESCRIPTION

[0053] For the convenience of those skilled in the art, the present application will be further described below in conjunction with the embodiments and drawings, and the content mentioned in the embodiments is not a limitation of the present application.

[0054] Please refer to Figures 1 to 12 As shown in the drawings, the shock-absorbing flow guide structure comprises a shock-absorbing flow guide piece 104, which is integrally formed by an elastic material, and comprises a cylindrical part 112 and an air collecting part 113.

The air collecting part 113 and the cylindrical part 112 are arranged in unilateral alignment. A plurality of shock-absorbing protrusions 115 are arranged on the outer surface of the cylindrical part 112 at intervals.

[0055] A straightener comprises a first clamping plate 1, a second clamping plate 2 and a resilient member 3, the first clamping plate 1 and the second clamping plate 2 are hingedly connected at one end and can be opened and closed to receive and clamp hair at the other end, and the resilient member 3 is used to restore the two clamping plates to an open state; the first clamping plate 1 or the second clamping plate 2 comprises a housing member 100, a blowing unit 101, a cover member 102, a perming unit 103 and a shock-absorbing flow guide member 104, both ends of the housing member 100 are a handle portion 105 and a perming portion 106 respectively, the cover member 102 is detachably connected with the handle portion 105, the shock-absorbing flow guide member 104 is located between the handle portion 105 and the cover member 102, the shock-absorbing flow guide member 104 is sleeved on the outside of the blowing unit 101, the perming unit 103 is arranged in the perming portion 106, and the two opposite perming units 103 are located on the side where the two clamping plates are close to each other, and the perming portion 106 is provided with an air outlet hole 107 in communication with the shock-absorbing flow guide member 104.

[0056] The first clamping plate 1 and the second clamping plate 2 are rotatably connected, and the resilient member 3 is used to restore the two clamping plates to an open state; meanwhile, the blowing unit 101, the perming unit 103 and the shock-absorbing flow guide member 104 are integrated, which not only improves the straightening efficiency, but also optimizes the airflow path through the shock-absorbing flow guide member 104, reduces vibration, ensures smooth air outlet, realizes the dual functions of rapid drying and straightening, and the detachable design of the cover member 102 facilitates maintenance and cleaning.

[0057] The straightener is also provided with an air guide plate 110 on the housing member 100, an air containing chamber 108 is formed between the air guide plate 110 and the housing member 100, the shock-absorbing flow guide member 104 and the air containing chamber 108 are in communication to form a first air duct 109, the external fluid sucked by the blowing unit 101 flows along the first air duct 109, is divided by the air guide plate 110 and is quickly discharged from the air outlet hole 107 to form cold air, and the cold air quickly cools and shapes the hair heated by the perming unit 103.

[0058] The straightener is provided with the air guide plate 110 on the housing member 100, and the air containing chamber 108 is formed between the air guide plate 110 and the housing member 100, which effectively optimizes the airflow channel. The shock-absorbing flow guide member 104 and the air containing chamber 108 are in communication to form the first air duct 109, the cold air blown by the blowing unit 101 flows through the first air duct 109 and is divided by the air guide plate 110 and is uniformly discharged from the air outlet hole 107. The cold air not only helps to alleviate the damage of heat to the hair, but also helps the hair to cool and shape quickly after being heated by the perming unit 103, and provides a more smooth and natural effect. At the same time, the design enhances the stability and comfort of the product, and ensures the efficient drying and shaping functions.

[0059] When the blowing unit 101 and the shock-absorbing flow guide 104 are arranged on the second clamping plate 2, the air outlet holes 107 are arranged on the bottom surface and the side edge of the housing 100 of the second clamping plate 2 and are arranged along the length direction of the housing 100, which ensures smooth air blowing of the blowing unit 101.

[0060] The shock-absorbing flow guide 104 is integrally formed by using an elastic material, and the air flow guide plate 110 is arranged on one side of the shock-absorbing flow guide 104 and is provided with a hollow annular platform 111. The shock-absorbing flow guide 104 comprises a cylindrical portion 112, and one end of the cylindrical portion 112 is provided with a wind collecting portion 113 which is used in cooperation with the hollow annular platform 111. The hollow annular platform 111 is arranged in the wind collecting portion 113, and the hollow annular platform 111 is used for connecting the air chamber 108 and the cylindrical portion 112, and the blowing unit 101 is arranged in the cylindrical portion 112. The shock-absorbing flow guide 104 further comprises a hollow tapered portion 114 which connects the cylindrical portion 112 and the wind collecting portion 113. The inner hole diameter of the hollow tapered portion 114 gradually increases along the direction from the wind collecting portion 113 to the cylindrical portion 112. A plurality of shock-absorbing protrusions 115 are arranged on the outer surface of the cylindrical portion 112 at intervals. The shock-absorbing protrusions 115 on the cylindrical portion 112 abut against the inner wall of the cover plate 102 and / or the inner wall of the housing 100 to reduce the vibration and noise generated by the shock-absorbing flow guide 104 during operation.

[0061] Preferably, with particular reference to Figure 11 As shown in the figure, the cross-sectional air passing area B of the wind collecting portion 113 is smaller than the cross-sectional air passing area A of the cylindrical portion 112, and 0.1A≤B≤0.2A. This can ensure that the air flow passing through the wind collecting portion 113 is accelerated even at a low rotating speed of the blowing unit 101. Of course, the cross-sectional air passing area B of the wind collecting portion 113 cannot be too small. If B<0.1A, the noise will increase and the air volume cannot meet the design requirements of the product.

[0062] Since the temperature of the hair ironing unit 103 can reach 230 to 240 degrees Celsius during operation of the product, if the distance between the wind collecting portion 113 and the hair ironing unit 103 is too short, the aging of the wind collecting portion 113 will be accelerated and its performance will be affected. Therefore, the wind collecting portion 113 is arranged as close as possible to the inner surface of the housing 100, and the hair ironing unit 103 is arranged as far away as possible from the housing 100 to increase the distance between them. In this embodiment, the wind collecting portion 113 and the cylindrical portion 112 are arranged in a non-concentric shaft manner, i.e., the wind collecting portion 113 and the cylindrical portion 112 are arranged in unilateral alignment.

[0063] The hollow annular table 111 is in communication with the cylindrical part 112, which ensures that the cold air generated by the air blowing unit 101 can flow efficiently and form a smooth air flow path through the air collecting part 113 and the hollow cone part 114. The gradually increasing design of the inner hole of the hollow cone part 114 helps to guide the air flow to be distributed more uniformly, avoiding the obstruction of the air flow. At the same time, the cylindrical part 112, as part of the shock-absorbing guide part 104, is made of elastic material and is provided with multiple shock-absorbing protrusions 115, which are in contact with the inner wall of the cover plate 102 or the shell 100, further reducing the vibration and noise generated during use, improving the user's comfort experience, and enhancing the stability and durability of the device.

[0064] The outer side of the hollow annular table 111 is provided with a plurality of boss rings 116, which are arranged along the length direction of the hollow annular table 111. All the boss rings 116 of the hollow annular table 111 are inserted into the air collecting part 113 in an interference fit. The air collecting part 113, as part of the shock-absorbing guide part 104, is made of elastic material, has strong connection stability and good sealing performance, and can ensure smooth flow of fluid.

[0065] The multiple boss rings 116 can provide additional support to prevent displacement or loosening during use. All the boss rings 116 are located inside the air collecting part 113 and are in contact with the inner side wall of the air collecting part 113. The air collecting part 113 is made of elastic material, which makes it able to adapt to different working environments and effectively resist external pressure, further improving the tightness and durability of the structure. This design optimizes the guidance and control of air flow, while reducing the noise generated by vibration and friction, thereby improving the stability and comfort of the straightening iron during use.

[0066] The first clamping plate 1 is provided with an opening and closing guide rail sliding groove 4, and the second clamping plate 2 is provided with an opening and closing locking device 5. The opening and closing locking device 5 includes an opening and closing guide rail sliding block 6 and a sliding member 7. The opening and closing guide rail sliding groove 4 is arranged on the opening and closing locking device 5 to form a sliding chamber 8. The sliding member 7 is slidingly arranged in the sliding chamber 8. The opening and closing guide rail sliding block 6 is further provided with a limiting portion 9. When the sliding member 7 is slid to the end away from the limiting portion 9, the elastic member 3 is released, and the first clamping plate 1 and the second clamping plate 2 are in an open state. When an external force is applied to keep the first clamping plate 1 and the second clamping plate 2 closed, the sliding member 7 is slid to the end close to the limiting portion 9 and slides into the limiting portion 9. The limiting portion 9 limits the sliding member 7 and compresses the elastic member 3. The cooperation between the sliding member 7 and the limiting portion 9 enables the first clamping plate 1 and the second clamping plate 2 to remain in a closed state after the external force is released.

[0067] The opening and closing lock 5 comprises an opening and closing guide rail slider 6 and a sliding piece 7, the sliding piece 7 can freely slide in a sliding chamber 8. When the sliding piece 7 slides away from the limiting part 9, the sliding piece 7 is released, so as to drive the elastic piece 3 to relax, the first clamping plate 1 and the second clamping plate 2 are in an open state; when the sliding piece 7 slides towards the limiting part 9 after an external force is applied to keep the first clamping plate 1 and the second clamping plate 2 in a closed state, the sliding piece 7 slides into the limiting part 9 and is limited by the limiting part 9, the cooperation between the sliding piece 7 and the limiting part 9 enables the first clamping plate 1 and the second clamping plate 2 to still be in a closed state after the external force is released. This design simplifies the opening and closing mechanism, makes the opening and closing of the clamping plate more stable, is convenient to operate, guarantees the stability of the structure, and improves the user experience.

[0068] The opening and closing guide rail groove 4 is provided with a first protrusion 11, the opening and closing lock 5 is provided with a second protrusion 12, one end of the elastic piece 3 is installed on the first protrusion 11, and the other end is installed on the second protrusion 12.

[0069] The design of the first protrusion 11 and the second protrusion 12 not only improves the stability of the elastic piece 3, but also effectively avoids excessive stretching or compression of the elastic piece 3, enhances the durability and reliability of the structure, and ensures that the clamping plate can be accurately in an open or closed state.

[0070] The sliding piece 7 comprises a locking slider 13 and a locking cover 14, the locking slider 13 is provided with a mounting groove 15, the bottom surface of the opening and closing guide rail groove 4 is provided with a strip hole 16, the locking cover 14 comprises a sliding part 17 slidingly arranged on the first clamping plate body and a sliding rod 18 arranged on the sliding part 17, the locking cover 14 is accommodated in the mounting groove 15 through the strip hole 16 via the sliding rod 18, and after the sliding part 17 is slid, the sliding rod 18 drives the locking slider 13 to reciprocate in the sliding chamber 8.

[0071] The locking slider 13 is provided with a lock 19 on one side close to the limiting part 9, when the locking cover 14 drives the locking slider 13 to slide towards one side close to the limiting part 9 after an external force is applied to keep the first clamping plate 1 and the second clamping plate 2 in a closed state, the lock 19 is limited in the limiting part 9, so that the first clamping plate 1 and the second clamping plate 2 can still be in a closed state after the external force is released.

[0072] The latch 19 is used to precisely limit the locking slider 13 with the limiting part 9, to ensure that the slider does not deviate or misoperate during the opening and closing of the sliding part 7. When the locking slider 13 approaches the limiting part 9, the latch 19 enters the limiting part 9, so that the slider cannot continue to slide, thereby keeping the first clamping plate 1 and the second clamping plate 2 in a closed state. Conversely, when the sliding part 7 is away from the limiting part 9, the latch 19 is released, and the first clamping plate 1 and the second clamping plate 2 return to the open state under the elastic force of the elastic member 3. This design effectively prevents unstable movement of the locking slider 13, improves the safety, reliability and precision of the opening and closing mechanism, and ensures smooth operation and service life of the device.

[0073] The locking slider 13 side is also provided with an elastic limiting arm 21, and the side of the elastic limiting arm 21 is provided with a protruding part 22, which is used to resist the inner side wall of the opening and closing guide rail slider 6 to prevent the locking slider 13 from falling off.

[0074] By providing the elastic limiting arm 21 on the side of the locking slider 13, and providing the protruding part 22 on the side of the elastic limiting arm 21, the locking slider 13 is effectively prevented from falling off or deviating during the opening and closing process. The elastic limiting arm 21 provides a certain elastic resistance to ensure that the locking slider 13 always stays in the correct position. When the locking slider 13 moves in the sliding chamber 8, the protruding part 22 will contact the inner side wall of the opening and closing guide rail slider 6, avoiding the slider from falling off or unstable movement.

[0075] The protruding part 22 is a hemispherical structure. The design of the hemispherical protruding part 22 not only prevents the sliding part 7 from falling off, but also increases the contact area between the sliding part 7 and the opening and closing guide rail slider 6, enhancing the stability of the connection.

[0076] The hair straightening unit 103 of the first clamping plate 1 and the second clamping plate 2 is provided with a buffer 33 on the side close to the housing member 100, and the inner bottom surface of the housing member 100 is provided with a containing groove 34, and the buffer 33 is installed in the containing groove 34.

[0078] The air guide plate 110 includes a first plate body 200 arranged on the perming unit 103, and an air guide unit 201 arranged on the first plate body 200, the air guide unit 201 having an air guide strip 202 including an air guide rib 203 arranged along the length direction of the first plate body 200, and an arc-shaped tail wing 204 arranged along the width direction of the first plate body 200.

[0079] The straightening device further includes a control assembly 27 electrically connected with the perming unit 103 and the blowing unit 101, the control assembly 27 drives the perming unit 103 to heat and straighten external hair, and the control assembly 27 drives the blowing unit 101 to suck cold air from the outside, flow the cold air to the perming part 106 through the shock-absorbing guide part 104, and then discharge the cold air through the air outlet hole 107 to quickly cool and shape the external hair.

[0080] The air guide unit 201 includes two air guide strips 202, the air guide ribs 203 of the two air guide strips 202 are arranged in parallel, the air guide ribs 203 of the two air guide strips 202 are located between the arc-shaped tail wings 204 of the two air guide strips 202, the two air guide strips 202 are arranged in a spaced manner on the first plate body 200, and a second air duct 205 is formed between the two air guide strips 202.

[0081] When the air guide unit 201 comprises two parallel air guide strips 202, the second air duct 205 formed between the two air guide strips 202 further promotes the uniform distribution and efficient use of cold air. In specific implementation, the user can start the hair ironing unit 103 and the hair blowing unit 101 through the control assembly 27. Under the joint action of the air guide member and the air guide plate 110, the cold air is guided and distributed by the air guide rib 203, and then the wind direction and intensity are adjusted by the arc tail wing 204, so that the cold air uniformly and efficiently acts on the heated hair, and a fast and high-quality cooling and styling effect is achieved.

[0082] The number of air guide units 201 on the air guide plate 110 is multiple groups, and the multiple groups of air guide units 201 are arranged along the length direction of the air guide plate 110. The side close to the air guide member is the first group of air guide units 201, the side away from the air guide member of the first group of air guide strips 202 is the second group of air guide units 201, the width of the second air duct 205 between the two air guide strips 202 of the first group of air guide units 201 is greater than the width of the second air duct 205 between the two air guide strips 202 of the second group of air guide units 201, and the second air duct 205 of the first group of air guide units 201 is in communication with the second air duct 205 of the second group of air guide units 201.

[0083] The width of the second air duct 205 of the first group of air guide units 201 (close to the air guide member) is designed to be greater than the width of the second air duct 205 of the second group of air guide units 201 (away from the air 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, achieving precise focusing and efficient use of the cold air. The second air duct 205 of all air guide units 201 is in communication with each other, ensuring the continuous flow and uniform distribution of cold air on the entire air guide plate 110. In specific implementation, the user starts the hair ironing unit 103 and the hair blowing unit 101, and the cold air enters the air guide plate 110 under the guidance of the air guide member. After being gradually distributed and focused by the multiple groups of air guide units 201, the cold air uniformly and with high intensity acts on the heated hair, achieving a fast and long-lasting styling effect, and significantly improving the use efficiency and user experience of the hair straightener.

[0085] The single air guide rib 203 of the end air guide group 206 and the two arc-shaped tail wings 204 can efficiently gather the cold air at the end of the second air duct 205, and ensure the intensity and concentration of the cold air when the cold air finally acts on the hair. The second air ducts 205 of the whole air guide system are connected with each other, and the continuous, uniform and efficient flow of the cold air in the whole flow channel is ensured.

[0086] When the blowing unit 101 and the shock-absorbing guide 104 are arranged on the second clamping plate body, the outer side of the first clamping plate 1 is provided with the heat dissipation hole 32, and the heat dissipation hole 32 on the first clamping plate 1 is used to dissipate the heat generated by the hair ironing unit 103, so as to avoid the high temperature inside and on the surface of the shell 100 of the first clamping plate 1.

[0087] Since the first clamping plate 1 and the second clamping plate 2 are hingedly connected at one end and opened and closed at the other end, both are in a long and narrow shape, and when the other end is closed, the left and right sides are often offset, so that the two hair ironing units 103 are difficult to align and fit. In order to solve this problem or reduce the influence, the cover plate 102 is recessed and provided with a sliding limiting cavity 82, and the first clamping plate 1 is provided with a second cover plate 117 corresponding to the sliding limiting cavity 82, the second cover plate 117 is provided with a sliding first wall 41 protruding downward, the sliding first wall 41 slides in the sliding limiting cavity 82, the sliding first wall 41 forms an opening and closing guide rail sliding groove 4, the outer wall of the sliding cavity 8 is protruded upward to form a sliding second wall 81, the sliding second wall 81 slides in the opening and closing guide rail sliding groove 4, the top of the sliding second wall 81 extends into the sliding cavity 8 to form a limiting part 9, and when the product is closed, the limiting part 9 blocks or approaches the bottom of the opening and closing guide rail sliding groove 4, so that the locking block 13 structure can be more compact. The structure design not only solves or reduces the problem of left and right offset when the upper and lower clamping plates are closed, but also ingeniously simplifies the locking structure.

[0088] The above is only a preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation mode and application range can be changed, and the content of the specification should not be understood as a limitation of the present application.
