[0002] As the quality of life improves, people's requirements for their own beauty also increase. For example, some women like to use hair straightening equipment to straighten their hair to enhance their temperament.

[0003] Existing hair straightening devices typically include two hinged heating plates. These plates are preheated to a high temperature before use. The plates then clamp the hair and repeatedly stretch it along the hair to achieve straightening. However, due to the high temperatures of the plates, these devices can easily burn or scorch the hair, burn the user's hands, or damage other objects, making them less safe. Furthermore, using these devices often requires the user to frequently tighten and loosen the plates, which can easily fatigue the user's hands and make operation inconvenient.

[0073] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0074] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0075] First, it should be noted that the axial direction in this article refers to the direction parallel to the central axis of the cylindrical shell 1. The four directions of up, down, left and right in this article are all based on the attached Figure 5 The top, bottom, left and right directions of the currently displayed view are used as the reference.

[0076] Please refer to Figures 1 to 6 , Figure 1 A partial cross-sectional structural diagram of a hair straightening device provided by a specific embodiment of the present invention; Figure 2 for Figure 1 Explosion structure; Figure 3 for Figure 1 An exploded structure diagram of another view; Figure 4 for Figure 1 The main view; Figure 5 for Figure 4 Middle AA section; Figure 6 for Figure 1 Structural diagram of the middle and lower shell.

[0077] An embodiment of the present invention discloses a hair straightening device comprising a cylindrical housing 1. In this embodiment, the cylindrical housing 1 is preferably cylindrical. The cylindrical housing 1 has a drainage groove 2 extending axially. The drainage groove 2 is preferably a cylindrical groove coaxially disposed with the cylindrical housing 1, with one end open and the other closed.

[0078] A straight-flow cavity 3 intersecting the axial direction is defined within the cylindrical housing 1. This cavity 3 is surrounded by a plurality of side panels to separate the cavity 3 from the drainage trough 2. Preferably, the cavity 3 extends perpendicularly through the cylindrical housing 1, i.e., the centerline of the cavity 3 is perpendicular to the centerline of the cylindrical housing 1.

[0079] A drainage port 4 is provided between the drainage trough 2 and the hair-straightening chamber 3. The drainage port 4 directs the air blown into the drainage trough 2 into the hair-straightening chamber 3, thereby straightening the hair within the hair-straightening chamber 3. The walls of the drainage trough 2 include inner and outer flaps, respectively, disposed at the bottom of the hair-straightening chamber 3. The inner and outer flaps are radially offset from each other along the drainage trough 2. The cavity formed between the inner and outer flaps serves as the drainage port 4. That is, the drainage port 4 is located at the bottom of the hair-straightening chamber 3. After passing through the drainage port 4, the air within the drainage trough 2 is blown out from the bottom to the top of the hair-straightening chamber 3. This ensures that the air blown out of the drainage port 4 has a certain pressure, facilitating full utilization of the hair-straightening chamber 3 and facilitating increased length of hair being blown, thereby facilitating rapid hair straightening.

[0080] During use, the hair to be blown is placed in the hair straightening chamber 3 before air is blown from the guide groove 2. The air flowing into the guide groove 2 is pressurized after passing through the guide port 4, so that the air with a certain pressure is blown into the hair straightening chamber 3, thereby straightening the hair in the hair straightening chamber 3. This prevents the heated clamps from scalding the user's hair or hands, and provides greater safety and ease of operation. Therefore, the hair straightening device provided by the present invention can safely and conveniently stretch hair.

[0081] In this embodiment, the drainage channel 2 includes a left drainage channel 21 and a right drainage channel 22, symmetrically arranged on the left and right sides of the straight hair cavity 3. The wall of the left drainage channel 21, which is closer to the straight hair cavity 3, includes a left inner flap 211 and a left outer flap 212. The left inner flap 211 and the left outer flap 212 are radially staggered along the left drainage channel 21. The wall of the right drainage channel 22, which is closer to the other side of the straight hair cavity 3, includes a right inner flap 221 and a right outer flap 222. The right inner flap 221 and the right outer flap 222 are radially staggered along the right drainage channel 22.

[0082] Specifically, the left inner flap 211 and the right inner flap 221 are symmetrically arranged about the central symmetry plane of the straight hair chamber 3. Both are located on either side of the straight hair chamber 3 and have the same curvature. The left inner flap 211 bends from the left side of the straight hair chamber 3 toward the center of the left drainage groove 21, while the right inner flap 221 bends from the right side of the straight hair chamber 3 toward the center of the right drainage groove 22. The left outer flap 212 is located outside the left inner flap 211, while the right outer flap 222 is located outside the right inner flap 221. The left and right outer flaps 212 and 222 are also symmetrically arranged about the central symmetry plane of the straight hair chamber 3 and have the same curvature. The left outer flap 212 bends from the left bottom of the straight hair chamber 3 toward the center of the left drainage groove 21, while the right outer flap 222 bends from the right bottom of the straight hair chamber 3 toward the center of the right drainage groove 22.

[0083] In this embodiment, the cross-section of the hair straightening chamber 3 is tapered. Specifically, the vertical distance between the left inner flap 211 and the right inner flap 221 gradually decreases from the bottom to the top of the hair straightening chamber 3, and the vertical distance between the left outer flap 212 and the right outer flap 222 also gradually decreases from the bottom to the top of the hair straightening chamber 3. That is, the larger diameter end of the upper tapered hair straightening chamber formed by the left inner flap 211 and the right inner flap 221 is opposite the smaller diameter end of the lower tapered hair straightening chamber formed by the left outer flap 212 and the right outer flap 222. Crucially, the maximum vertical distance between the left inner flap 211 and the right inner flap 221 is greater than the vertical distance between the left outer flap 212 and the right outer flap 222. That is, the larger diameter end of the upper tapered hair straightening chamber is always wider than the smaller diameter end of the lower tapered hair straightening chamber. This increases the pressure from the bottom to the top of the hair straightening chamber 3, further enhancing the hair straightening effect.

[0084] Please refer to Figures 7 to 17 , Figure 7 This is a structural diagram of a hair straightening device provided by the present invention, which is equipped with a left clamping plate and a right clamping plate; Figure 8 for Figure 7 Cross-sectional structural diagram; Figure 9 It is the main view of 7; Figure 10 for Figure 9 Middle BB section; Figure 11 for Figure 10 A partial enlarged view of center C; Figure 12 for Figure 7 Exploded diagram; Figure 13 for Figure 7 Assembly structure diagram of the middle and lower shell, left and right splints; Figure 14 for Figure 13 Another view of; Figure 15 for Figure 13 Structural diagram of the middle left limit plate; Figure 16 It is an assembly structure diagram between the left clamping piece and the left guide clamping plate with the left thrust plate; Figure 17 for Figure 7 Assembly structure diagram between the left middle clip, left guide plate and left stopper.

[0085] The present invention further includes a left clamping plate 23 and a right clamping plate 24, respectively disposed on the left outer flap 212 and the right outer flap 222. The left clamping plate 23 and the right clamping plate 24 elastically counteract each other to straighten the hair within the hair straightening chamber 3 by virtue of the elastic force. During use, the user manually pulls the hair between the left clamping plate 23 and the right clamping plate 24, causing the hair to overcome the elastic force between the left clamping plate 23 and the right clamping plate 24. Therefore, the elastic force between the left clamping plate 23 and the right clamping plate 24 is set according to actual conditions to ensure a good user experience.

[0086] In this specific embodiment, the left clamping plate 23 includes a left clamping piece 231 , a left abutting piece 232 , a left abutting post 233 , a left elastic member 234 and a left connecting piece 235 .

[0087] The left clip 231 extends axially, is parallel to the central symmetry plane of the hair straightening chamber 3, and is located at the bottom of the hair straightening chamber 3 for straightening hair.

[0088] The inner wall of the left outer flap 212 is provided with a left abutting groove 2121 , which is a rectangular groove extending in the axial direction. The left abutting piece 232 is installed in the left abutting groove 2121 .

[0089] One side of the left abutting piece 232 abuts against the inner sidewall of the left abutting groove 2121, while the other side is fixed to a left abutting post 233, which is perpendicular to the left abutting piece 232. The length of the left abutting post 233 is shorter than the width of the left abutting groove 2121, providing space for the installation of the left elastic member 234. The number of left abutting posts 233 provided depends on actual conditions.

[0090] The left elastic member 234 is mounted one-to-one with the left abutment post 233. Its two ends elastically abut against the left abutment piece 232 and the left abutment groove 2121, respectively. When the user inserts hair into the hair straightening chamber 3, the hair presses against the left clip 231, causing the left elastic member 234 to contract, creating space for the hair to enter. The elastic force of the left elastic member 234 also straightens the hair. In its natural state, the left elastic member 234 remains contracted, maintaining elastic contact between the left clip 231 and the right clip 241. The left elastic member 234 is specifically, but not limited to, a conventional cylindrical spring.

[0091] The left connecting piece 235 is parallel to the central axis of the straight hair chamber 3 and is vertically fixed between the left clamping piece 231 and the left abutting piece 232 to vertically connect the two. The left connecting piece 235 is set according to the width of the bottom of the straight hair chamber 3 and is not specifically limited here.

[0092] In this specific embodiment, the left clamping plate 23 and the right clamping plate 24 are preferably both aluminum plates, which are convenient for absorbing the heat of the hot air in the drainage groove 2, and are convenient for using the left clamping plate 23 and the right clamping plate 24 to heat the hair during the process of straightening the hair, so as to facilitate quick straightening of the hair.

[0093] To enhance versatility, the left clamping plate 23 and the right clamping plate 24 share the same structure, and both are arranged symmetrically about the central plane of symmetry of the hair straightening chamber 3. The right clamping plate 24 comprises a right clip 241, a right abutting plate 242, a right abutting post 243, a right elastic member 244, and a right connecting piece 245. The right clip 241 abuts against the left clip 231 to straighten hair. The materials and effective working lengths of the two clips are determined based on practical needs and are not limited here. The right abutting plate 242 is mounted within a right abutting groove provided on the inner wall of the right outer flap 222. The right abutting post 243 is perpendicularly positioned to the side of the right abutting plate 242. The right elastic member 244 is sleeved over the right abutting post 243, with its ends elastically abutting against the right abutting groove and the right abutting plate 242, respectively. The right connecting piece 245 is vertically fixed between the right clip 241 and the right abutting plate 242.

[0094] In this specific embodiment, the present invention also includes a left limit plate 61 and a right guide plate 62. The left limit plate 61 is fixed to the inner wall of the left outer flap 212, and the bottom of the left limit plate 61 is against the top of the left clamping plate 23, which is used to limit the position of the left clamping plate 23; the right guide plate 62 is fixed to the inner wall of the right outer flap 222, and the right guide plate 62 is against the top of the right clamping plate 24, which is used to limit the position of the right clamping plate 24, so that the left clamping plate 23 and the right clamping plate 24 can only move horizontally along a plane perpendicular to the straight hair cavity 3, and limit the left clamping plate 23 and the right clamping plate 24 to move in a direction parallel to the central axis of the straight hair cavity 3.

[0095] Specifically, the inner wall of the left outer flap 212 is provided with a left limiting groove extending in the axial direction, and the left limiting plate 61 is installed in the left limiting groove. The left limiting plate 61 is provided with a left limiting block that cooperates with the left limiting groove. The left limiting groove and the left limiting block are in interference fit, thereby securing the left limiting plate 61 in the left outer flap 212. The inner wall of the right outer flap 222 is provided with a right limiting groove extending in the axial direction. The right guide plate 62 is installed in the right limiting groove. The right guide plate 62 is provided with a right limiting block that cooperates with the right limiting groove. The right limiting groove and the right limiting block are in interference fit, thereby securing the right guide plate 62 in the right outer flap 222.

[0096] The left limiting plate 61 has an arc-shaped air guide surface for guiding the wind to be discharged from the left drainage groove 21. At the same time, the right limiting plate 62 also has an arc-shaped air guide surface for guiding the wind to be discharged from the right drainage groove 22. The arc-shaped air guide surface is specifically arc-shaped. Specifically, the arc-shaped air guide surface located at the left air guide port 41 is specifically bent from the bottom of the straight hair cavity 3 to the center of the left drainage groove 21, and the arc-shaped air guide surface located at the right air guide port 42 is specifically bent from the bottom of the straight hair cavity 3 to the center of the right drainage groove 22, so as to avoid excessive exhaust resistance at the left guide port 41 and the right guide port 42, and ensure that the wind discharged from the bottom of the straight hair cavity 3 has sufficient pressure.

[0097] In this specific embodiment, the drainage port 4 includes a left drainage port 41 and a right drainage port 42. The left drainage port 41 is arranged between the left inner flap 211 and the left outer flap 212, and the right drainage port 42 is arranged between the right inner flap 221 and the right outer flap 222. The slot widths of the two are equal, and the two are symmetrically arranged with the central symmetry plane of the straight hair cavity 3 as the center.

[0098] The present invention also includes a plurality of left guide plates 71 and a plurality of right guide plates 72, wherein the left guide plate 71 is arranged between the left inner flap 211 and the left outer flap 212, and the left guide plate 71 is located at the left guide port 41 to ensure that the left guide port 41 discharges air evenly; the right guide plate 72 is arranged between the right inner flap 221 and the right outer flap 222, and the right guide plate 72 is located at the right guide port 42 to ensure that the right guide port 42 discharges air evenly.

[0099] In this specific embodiment, all left guide plates 71 are vertically fixed to the side of the left limit plate 61 away from the left clamping plate 23, and all left guide plates 71 are abutted against the bottom of the left inner flap 211. The top of each left guide plate 71 is provided with an abutment groove abutting against the left inner flap 211. All left guide plates 71 are staggered along the axial direction and are used to separate the left guide port 41, so that the wind in the left guide groove 21 is evenly blown into the hair straightening chamber 3, so that the hair straightening chamber 3 can evenly straighten the hair.

[0100] Similarly, all right guide plates 72 are vertically fixed to the side of the right limit plate 62 away from the right clamping plate 24, and all right guide plates 72 are abutted against the bottom of the right inner flap 221. Each right guide plate 72 is also provided with an abutment groove abutting against the right outer flap 222. All right guide plates 72 are staggered along the axial direction and are used to separate the right guide port 42, so that the wind in the right guide groove 22 is evenly blown into the hair straightening chamber 3, so that the hair straightening chamber 3 can further evenly straighten the hair.

[0101] All left deflectors 71 are integrally formed by injection molding on the inner side of the left outer flap 212, and all right deflectors 72 are integrally formed by injection molding on the inner side of the right outer flap 222. Furthermore, the deflectors 71 and right deflectors 72 evenly space the air outlets 4 on both sides of the cylindrical housing to ensure uniform air flow.

[0102] Of course, a series of left limit plates 61 having a number of left guide plates 71 passing therethrough and a series of right guide support plates 62 having a number of right guide plates 72 passing therethrough can also be provided. By changing the axial distance between any two adjacent left guide plates 71 or the axial distance between any two adjacent right guide plates 72, the smaller the axial distance between any two adjacent left guide plates 71 or the axial distance between any two adjacent right guide plates 72, the greater the wind pressure at the bottom of the hair straightening chamber 3, thereby allowing the user to change the wind pressure at the bottom of the hair straightening chamber 3 as needed, thereby meeting the hair quality requirements of different users and further improving the user experience.

[0103] To further enhance convenience, a guide opening 5 is provided at one end of the cylindrical housing 1, communicating with the hair straightening chamber 3. This allows hair to enter the straightening chamber 3, making operation more convenient and more user-friendly. Preferably, the guide opening 5 is trumpet-shaped, with the smaller end of the trumpet-shaped guide opening connected to the straightening chamber 3, facilitating the insertion of hair.

[0104] Specifically, the trumpet-shaped guide port includes a left guide plate 51 and a right guide plate 52 that are oppositely arranged, and the two guide plates are distributed in a trumpet shape.

[0105] The left guide plate 236 is provided at one end of the left clamping plate 23 close to the left guide plate 51, and the front end of the left guide plate 236 is adjacent to and abuts against the rear end of the left guide plate 51. The left guide plate 236 is used to guide the hair guided by the left guide plate 51 to continue between the left clamping plate 23 and the right clamping plate 24. Similarly, the right clamping plate 24 is provided at one end close to the right guide plate 52, and the front end of the right guide plate 246 is adjacent to and abuts against the rear end of the right guide plate 52. The right guide plate 246 is used to guide the hair guided by the right guide plate 52 to continue between the left clamping plate 23 and the right clamping plate 24. The left guide plate 236 cooperates with the right guide plate 246 to enable the hair entering the guide opening 5 to quickly enter the hair straightening chamber 3 and between the left clamping plate 23 and the right clamping plate 24, thereby preventing the hair from accumulating at the guide opening 5 due to the clamping resistance between the left clamping plate 23 and the right clamping plate 24, which is conducive to improving the convenience of use for the user. The left guide plate 236 and the right guide plate 246 are also distributed in a trumpet shape, and their large diameter ends are connected to the small diameter ends of the trumpet-shaped guide openings.

[0106] In this embodiment, the left guide plate 236 is integrally provided with a left thrust plate 2361 that selectively abuts against the side of the left clamping piece 231. Specifically, the left thrust plate 2361 abuts against the end of the left guide plate 236 near the right clamping piece 246. The right guide plate 246 is integrally provided with a right thrust plate that selectively abuts against the side of the right clamping piece 241. Specifically, the right thrust plate abuts against the end of the right guide plate 246 near the left guide plate 236. Crucially, the left and right guide plates 236 and 246 elastically abut against opposite sides of the hair straightening chamber 3, respectively.

[0107] Specifically, two opposite sides of the straight hair chamber 3 are provided with clamping grooves for respectively installing the left guide clamping plate 236 and the right guide clamping plate 246, and two opposite sides of the clamping groove are respectively fixed with clamping springs, so that the left guide clamping plate 236 and the clamping groove and the right guide clamping plate 246 and the clamping groove are elastically abutted, thereby achieving elastic abutment between the left guide clamping plate 236 and the right guide clamping plate 246.

[0108] When the hair enters between the left guide plate 236 and the right guide plate 246, the left push-stop plate 2361 pushes the left clip 231, and at the same time the right push-stop plate pushes the right clip 241, so that the left clip 231 and the right clip 241 move away from each other, allowing the hair to enter between the left clip 231 and the right clip 241; when the hair enters between the left clip 231 and the right clip 241, the left push-stop plate 2361 moves away from the left clip 231, and at the same time the right push-stop plate moves away from the right clip 241, and after the left clip 231 and the right clip 241 are separated from the hair, they rely on elastic force to restore elastic deformation until the left clip 231 and the right clip 241 are restored to elastic resistance, thereby preventing the hair from falling out from between the left clip 231 and the right clip 241, thereby improving the user experience.

[0109] Of course, the left side clip 231 and the left guide plate 236 can also be connected as one piece, and the right side clip 24 and the right guide plate 246 are also connected as one piece. The left guide plate 236 and the right guide plate 246 are respectively provided with a left stop plate 237 and a right stop plate on the opposite sides. The left stop plate 237 and the right stop plate elastically offset each other, which can also prevent hair from falling out from between the left side clip 231 and the right side clip 241, which can also improve the user experience.

[0110] Please refer to Figures 18 to 21 , Figure 18 A structural diagram of a hair straightening device provided by the present invention and equipped with an elastic plate; Figure 19 for Figure 8 Diagram of the natural state of a neutral elastic plate; Figure 20 for Figure 8 Diagram of the elastic plate in the open state; Figure 21 for Figure 18 Structural diagram of the intermediate elastic plate.

[0111] The present invention also includes an elastic plate 9 disposed in the guide port 5 and used to selectively block the guide port 5. The elastic plate 9 cooperates with the hair straightening cavity 3 to form a cavity with a closed outer surface, thereby preventing hair from escaping from the hair straightening cavity 3 and providing a better user experience.

[0112] In this embodiment, the elastic plate 9 includes a left elastic plate 91 and a right elastic plate 92, which are arranged in an arc shape and elastically abut each other. The left elastic plate 91 is disposed on the left guide plate 51, and the right elastic plate 92 is disposed on the right guide plate 52. Specifically, the left elastic plate 91 and the right elastic plate 92 are both arc-shaped, which can increase the hair clamping space to a certain extent. The left elastic plate 91 and the right elastic plate 92 are preferably made of materials such as plastic or silicone.

[0113] Furthermore, to facilitate the disassembly and assembly of the elastic plate 9, the left elastic plate 91 is slidably mounted on the left guide plate 51, and the right elastic plate 92 is slidably mounted on the right guide plate 52, so that the user can conveniently disassemble and assemble the left elastic plate 91 and the right elastic plate 92 as needed. Specifically, mutually cooperating engaging grooves and engaging sliders are provided between the left elastic plate 91 and the left guide plate 51, and between the right elastic plate 92 and the right guide plate 52. The engaging grooves are specifically T-shaped grooves provided on the left guide plate 51 and the right guide plate 52, respectively, and the engaging sliders are specifically T-shaped sliders provided on the ends of the left elastic plate 91 and the end of the right elastic plate 92, respectively. Of course, interchanging the positions of the engaging grooves and the engaging sliders, or changing the structures of the engaging grooves and the engaging sliders does not affect the purpose of the present invention.

[0114] In this embodiment, a plurality of hair deflectors 8 are disposed on the outer periphery of the cylindrical housing 1 near one end of the guide opening 5. Each hair deflector 8 extends along the centerline of the straightening chamber 3 to block hair outside the guide opening 5 from entering the guide opening 5, preventing excessive hair from entering the straightening chamber 3. This ensures that the straightening chamber 3 straightens an appropriate amount of hair each time, thereby enhancing the straightening effect. In this embodiment, the hair deflectors 8 extend perpendicular to the axial direction and are symmetrically disposed on two transition plates, which are symmetrically connected between each guide plate and the outer periphery of the cylindrical housing 1.

[0115] Preferably, the cylindrical housing 1 includes a cooperating upper housing 11 and lower housing 12, both of which are preferably semicircular in shape. Cooperating buckles and latch holes 122 are provided between the upper and lower housings 11, 12 to securely connect the upper and lower housings 11, 12. This facilitates disassembly of the upper and lower housings 11, 12, and facilitates the timely removal of hair accumulated in the left and right drainage grooves 21, 22. This prevents the left air guide port 41 from being clogged by hair, ensures uniform wind force within the straightening chamber 3, and promotes improved straightening results. Preferably, the buckles are evenly distributed along the side edges of the upper housing 11, and the side edges of the lower housing 12 are evenly distributed with a plurality of latching seats, each corresponding to the buckles. The free end of each latching seat is provided with a latch hole 122 that engages with the buckle. Of course, the method of securing the upper and lower housings 11, 12 is not limited to this.

[0116] The upper shell 11 and the lower shell 12 are respectively provided with an upper straight hole 111 and a lower straight hole 121. The upper straight hole 111 and the lower straight hole 121 are arranged opposite each other and coaxially. Specifically, the upper straight hole 111 is a waist-shaped through hole extending through the upper shell 11, and the lower straight hole 121 is similarly a waist-shaped through hole extending through the lower shell 12. It should be noted that both the upper straight hole 111 and the lower straight hole 121 are provided with a connection port that communicates with the guide port 5. Of course, the configuration of the upper straight hole 111 and the lower straight hole 121 is not limited to a waist-shaped configuration.

[0117] An upper side panel 112 extending perpendicularly to the axial direction is fixedly disposed on the inner side of the upper straight-emission hole 111. The inner side of the upper straight-emission hole 111 refers to the side of the upper straight-emission hole 111 that is adjacent to the lower housing 12. Of course, the side panel forming the straight-emission cavity 3 can also be disposed on the inner side edge of the lower straight-emission hole 121. The inner side of the lower straight-emission hole 121 refers to the side of the lower straight-emission hole 121 that is adjacent to the upper housing 11, without affecting the objectives of the present invention. It should be noted that the arrows in the accompanying drawings indicate the direction of wind flow.

[0118] The upper side panel 112 includes a U-shaped side baffle 1121 positioned near the notch of the drainage trough 2, and a first side baffle 1122 and a second side baffle 1123 fixedly mounted on opposite sides of the U-shaped side baffle 1121. Accordingly, the U-shaped side baffle 1121, the first side baffle 1122, the upper shell 11, and the lower shell 12 define the left drainage trough 21, which communicates with the left air guide port 41. Similarly, the U-shaped side baffle 1121, the second side baffle 1123, the upper shell 11, and the lower shell 12 define the right drainage trough 22, which communicates with the right air guide port 42. Naturally, air flowing into the notch of the drainage trough 2 is evenly diverted into the left and right drainage troughs 21 and 22, allowing the air within the drainage trough 2 to be evenly blown into the hair straightening chamber 3, ensuring that the hair within the hair straightening chamber 3 is evenly straightened, effectively avoiding uneven straightening and further improving the straightening effect.

[0119] Specifically, the U-shaped side baffle 1121 protrudes toward the direction close to the notch of the drainage groove 2, and the left outer peripheral surface of the U-shaped side baffle 1121, the side of the first side baffle away from the straight hair chamber 3, the left inner side surface of the upper shell 11 and the left inner side surface of the lower shell 12 form a left drainage groove 21 extending along the axial direction. Similarly, the right outer peripheral surface of the U-shaped side baffle 1121, the side of the second side baffle away from the straight hair chamber 3, the right inner side surface of the upper shell 11 and the right inner side surface of the lower shell 12 form a right drainage groove 22 extending along the axial direction.

[0120] Please refer to Figures 22 to 23 , Figure 22 This is a diagram showing the initial state of a hair straightening device provided in a specific embodiment of the present invention; Figure 23 for Figure 22 A picture of the curly hair after being straightened.

[0121] Attach Figure 22 Based on the current view of the hair, the roots of the hair are located at the bottom of the straight hair chamber 3, and the tails of the hair are located at the top of the straight hair chamber 3, so as to ensure a better straightening effect by virtue of the traction force of the scalp on the hair.

[0122] Preferably, the working principle of the hair straightening device provided by the present invention is as follows:

[0123] A bunch of bent hair is manually introduced into the guide opening 5 in advance, and then the hair is pushed into the elastic plate 9, so that the hair enters the hair straightening chamber 3, and at the same time, the hair is clamped by the left clamping plate 23 and the right clamping plate 24; air with a certain pressure is blown into the notch of the guide groove 2 and blown evenly into the left guide groove 21 and the right guide groove 22. The air entering the left guide groove 21 is blown into the bottom of the hair straightening chamber 3 through the left guide opening 41, and the air entering the right guide groove 22 is blown into the bottom of the hair straightening chamber 3 through the right guide opening 42. The air in the hair straightening chamber 3 is blown out from the bottom to the top of the hair straightening chamber 3, thereby straightening the hair placed in the hair straightening chamber 3.

[0124] The present invention further provides a hair straightening device, comprising a hair dryer 10 and the aforementioned hair straightening device. The outlet of the hair dryer 10 is connected to the opening of the drainage groove 2 to provide an air source for the hair straightening device. The hair straightening device provided by the present invention has the same beneficial effects as the hair straightening device, and will not be described in detail here.

[0125] Preferably, the end of the cylindrical shell 1 close to the hair dryer 10 is provided with a snap-on protrusion 13 that is snap-connected with the hair dryer 10, preferably an annular protrusion provided on the inner side of the notch of the drainage groove 2, which facilitates the disassembly and assembly of the cylindrical shell 1 from the hair dryer 10, with little operation difficulty, which is conducive to further improving convenience.

[0126] The hair straightening device and hair straightening apparatus provided by the present invention are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the method and core concept of the present invention. At the same time, for those skilled in the art, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
