Description

Technical Field

[0001] This utility model relates to the field of hair styling tools, and in particular to hair straightening comb accessories and hair straighteners. Background Technology

[0002] In the hair care industry, hair styling products are constantly innovating and developing. In recent years, with the continuous advancement of technology and the increasingly diversified needs of consumers for hair care, the functions of hair styling products have continued to expand and enrich. Especially with the increasing popularity of emerging products such as high-speed hair dryers, combs, and multi-functional hair styling irons, users' expectations for the functions of hair styling products have reached a new level. They are no longer satisfied with single basic styling functions, but expect products to integrate multiple functions, achieving efficient styling while providing a convenient and comfortable user experience.

[0003] Existing hair straighteners typically have a fixed airflow direction, drawing in air from a fixed inlet and blowing heated air onto the hair through one or more fixed outlets. This fixed airflow design cannot adjust the airflow direction according to the combing direction. Therefore, the airflow may conflict with the combing action, preventing the hot or cold air from effectively reaching the hair being treated, thus reducing drying or styling efficiency. Furthermore, when the airflow and combing direction are inconsistent, it can easily cause hair breakage or split ends, affecting the user experience. Utility Model Content

[0042] The following is combined Figures 1 to 9 This invention describes a hair straightening comb accessory and hair straightener provided in an embodiment of the present invention.

[0043] The hair straightening comb accessory provided in this embodiment of the utility model includes: a housing 10, a movable comb tooth assembly 30, and a stop 100. The housing 10 is provided with an air inlet 112 and a cavity 111 that are interconnected, and the top surface of the housing 10 is also provided with a slot 213 that communicates with the cavity 111. The movable comb tooth assembly 30 is rotatably mounted at the slot 213, and the two sides of the movable comb tooth assembly 30 in the width direction form a first air outlet 40 and a second air outlet 50 between the slot 213 and the slot 213, respectively. The stop 100 includes a blocking part 120 and a venting part 110. The blocking part 120 is installed on the inner wall of the cavity 111, and the venting part 110 is connected to the blocking part 120. The venting part 110 is located within the frontal projection plane of the slot 213 on the stop 100. The first air outlet 40 and the second air outlet 50 are respectively connected to the air inlet 112 through the venting part.

[0044] Please see Figure 4 and Figure 9 The housing 10 has a cavity 111 extending along its extension direction. An air inlet 112 is provided on the housing 10, communicating with the cavity 111 for connection to an external air source. Please refer to [link / reference]. Figure 2 The top surface of the housing 10 is also provided with a slot 213, which is connected to the cavity 111, and the airflow in the cavity 111 can flow out through the slot 213.

[0045] In this embodiment, please refer to Figure 4 The movable comb tooth assembly 30 is rotatably mounted at the slot 213 between the first position and the second position. The two sides of the movable comb tooth assembly 30 in the width direction form a first air outlet 40 and a second air outlet 50 with the slot 213, respectively. It can be understood that there is a ring wall structure around the outside of the slot 213 on the housing 10. When the movable comb tooth assembly 30 is in the first position, the movable comb tooth assembly 30 and one side of the ring wall structure on the housing 10 form the first air outlet 40. When the movable comb tooth assembly 30 is in the second position, the movable comb tooth assembly 30 and the other side of the ring wall structure on the housing 10 form the second air outlet 50.

[0046] When the movable comb assembly 30 is in the first position, the first air outlet 40 is open, and the second air outlet 50 can be open or closed. When the movable comb assembly 30 is in the second position, the second air outlet 50 is open, and the first air outlet 40 can be open or closed.

[0047] For example, please refer to Figure 4The width of the movable comb tooth assembly 30 is set to be less than the width of the slot 213. When the movable comb tooth assembly 30 is in the first position, both the first air outlet 40 and the second air outlet 50 are open, and the opening degree of the first air outlet 40 is greater than that of the second air outlet 50. When the movable comb tooth assembly 30 is in the second position, both the first air outlet 40 and the second air outlet 50 are open, and the opening degree of the second air outlet 50 is greater than that of the first air outlet 40.

[0048] In some other implementations, the width of the movable comb assembly 30 can also be set to be greater than the width of the slot 213, that is, the movable comb assembly 30 covers the slot 213 (not shown in the figure). In this case, when the movable comb assembly 30 is in the first position, the first air outlet 40 is in the open state, while the second air outlet 50 can be in the closed state because the movable comb assembly 30 abuts against the top surface of the housing 10. When the movable comb assembly 30 is in the second position, the second air outlet 50 is in the open state, and the first air outlet 40 can be in the closed state because the movable comb assembly 30 abuts against the top surface of the housing 10.

[0049] like Figure 3 As shown, the first air outlet 40 and the second air outlet 50 can both be arranged along the extension direction of the cavity 111, that is, along the length direction of the movable comb assembly 30.

[0050] In this embodiment, the baffle 100 includes a blocking part 120 and a venting part 110 connected to each other. The blocking part 120 blocks the airflow, while the venting part 110 allows gas to flow. The blocking part 120 is connected to the inner wall of the cavity 111. The airflow in the cavity 111 is connected to the first air outlet 40 through the venting part 110, that is, the airflow can flow to the first air outlet 40 through the venting part 110. Similarly, the airflow in the cavity 111 is connected to the second air outlet 50 through the venting part 110, that is, the airflow can flow to the second air outlet 50 through the venting part 110.

[0051] The ventilation section 110 is located within the projection plane of the slot 213 onto the baffle 100. This means that the slot 213 covers the ventilation section 110 within the projection plane of the baffle 100, but not exactly. This arrangement ensures that the area directly below the first air outlet 40 and the second air outlet 50 is not entirely covered by the ventilation section 110. This prevents airflow from blowing out perpendicular to the top surface of the housing 10, thus allowing the airflow to follow the direction of hair combing during the user's hair styling process, improving the straightness of the combed hair.

[0052] This application does not limit the structure of the baffle 100. In some implementations, the vent 110 can be a single vent with a circular, elliptical, or polygonal cross-section. For example, the blocking part 120 is configured as an annular structure, with the vent 110 formed in the space inside the blocking part 120. In other implementations, please refer to... Figure 8 The ventilation section 110 can be a plate-shaped solid structure with multiple spaced ventilation holes. This configuration not only guides the airflow but also makes the airflow more uniform and reduces noise.

[0053] The hair straightening comb accessory provided in this embodiment of the utility model rotatably mounts the movable comb tooth assembly 30 at the slot 213. The two sides of the movable comb tooth assembly 30 in the width direction form a first air outlet 40 and a second air outlet 50 between them and the slot wall of the slot 213, respectively. The movable comb tooth assembly 30 can flexibly adjust the airflow direction according to the user's combing direction, so that the airflow can be precisely consistent with the hair combing direction. The baffle 100 is set in the cavity 111 by the shielding part 120, and the ventilation part 110 is set in the front projection plane of the slot 213 on the baffle 100. The airflow in the cavity 111 can flow to the first air outlet 40 or the second air outlet 50 through the ventilation part 110, avoiding the airflow blowing towards the first air outlet 40 or the second air outlet 50 in a direction perpendicular to the baffle 100, so that the airflow blows towards the hair as much as possible in the direction of hair combing, thereby improving the straightness of the hair after combing.

[0054] In some embodiments of this utility model, the ventilation section 110 is located within the projected plane of the movable comb assembly 30 onto the stop 100. Airflow within the cavity 111 enters the space between the stop 100 and the slot 213 via the ventilation section 110. Figure 7 As shown, the airflow flows along the inner wall of the movable comb assembly 30 towards the first air outlet 40 and the second air outlet 50, preventing the airflow from blowing vertically out in a direction perpendicular to the top surface of the housing 10, so that the airflow blows towards the hair as much as possible in the direction of hair combing, thereby improving the straightness of the hair after combing.

[0055] In some embodiments of this utility model, the venting part 110 is provided with a plurality of vent holes spaced apart from each other.

[0056] In some embodiments of this utility model, there may be one vent hole, which is located inside the projected surface of the movable comb assembly 30 on the stop 100. In some embodiments of this utility model, there may be multiple vent holes, spaced apart along the width direction of the stop 100. The size of each vent hole is not specifically limited, as long as all vent holes are located inside the projected surface of the movable comb assembly 30 on the stop 100. In some embodiments of this utility model, there may be multiple vent holes, spaced apart along the length direction of the stop 100. The size of each vent hole is not specifically limited, as long as all vent holes are located inside the projected surface of the movable comb assembly 30 on the stop 100. In some embodiments of this utility model, there may be multiple vent holes, such as... Figure 8 As shown, multiple vent holes are spaced apart along the width direction of the baffle 100 to form a row of vent holes, i.e., a vent hole group; further, the vent hole group is spaced apart along the length direction of the baffle 100 to ensure that all vent holes are located within the front projection plane of the movable comb assembly 30 on the baffle 100.

[0057] In some embodiments of this invention, the distance between the movable comb assembly and the baffle 100 along the air outlet direction of the vent 110 is 1mm-10mm. This helps guide the airflow and prevents the airflow from blowing out vertically in a direction perpendicular to the baffle 100 due to an excessively large distance between the baffle 100 and the movable comb assembly. Optionally, the distance between the movable comb assembly and the baffle 100 can be 1mm, 2mm, 5mm, 7.5mm, 8mm, 9mm, 9.6mm, 10mm, etc.

[0058] In some embodiments of the utility model, the movable comb tooth assembly 30 includes a movable comb tooth seat 31 and movable comb teeth 32, with the movable comb teeth 32 disposed on the outer wall surface of the movable comb tooth seat 31. The movable comb tooth seat 31 is rotatably mounted at the slot 213 between a first position and a second position.

[0059] Specifically, the movable comb tooth holder 31 is rotatably mounted at the slot 213. The movable comb tooth holder 31 can drive the movable comb teeth 32 to rotate within the slot 213, so that the movable comb tooth holder 31 is in a first position (near the second air outlet 50) or a second position (near the first air outlet 40). Figure 5 As shown, when the user combs their hair, the straightener attachment moves along the entire length of the hair. Figure 5 As shown in the direction M, the movable comb holder 31 moves along the direction of movement. This is due to the pushing action of the user's head. Figure 5 Rotate in the direction N shown to rotate to Figure 5 The first position shown. And when the user moves the straightener attachment along the entire length... Figure 5 When moving in the opposite direction to the indicated direction M, the movable comb holder 31 moves along the direction of the user's head under the pushing action of the user's head. Figure 5The direction opposite to the rotation direction N will rotate to the second position. In one embodiment, the movable comb tooth seat 31 is provided with pins at both ends in the length direction. The pins are fixed to the inner wall surface of the slot 213. The movable comb tooth seat 31 rotates around the pins, that is, the movable comb tooth seat 31 can drive the movable comb tooth 32 to rotate to the first position or the second position in the slot 213.

[0060] In the actual process of combing hair, when the movable comb tooth base 31 drives the movable comb teeth 32 to rotate to the first position, such as Figure 4 , Figure 5 and Figure 7 As shown, most of the airflow in cavity 111 is blown out along the hair through the first air outlet 40, while a small portion of the airflow is blown out through the second air outlet 50 and then flows along the outer wall of the movable comb base 31 back to the first air outlet 40, before being blown out along the hair. This ensures that the airflow direction is basically consistent with the hair combing direction, improving the straightness of the hair after combing and meeting user needs. When the movable comb base 31 drives the movable comb teeth 32 to rotate to the second position, most of the airflow in cavity 111 is blown out along the hair through the second air outlet 50, while a small portion of the airflow is blown out through the first air outlet 40 and then flows along the outer wall of the movable comb base 31 back to the second air outlet 50, before being blown out along the hair. This ensures that the airflow direction is basically consistent with the hair combing direction, improving the straightness of the hair after combing and meeting user needs.

[0061] In some embodiments of this utility model, the inner wall surface of the movable comb tooth seat 31 is provided with a first guide surface 311 near the first air outlet 40. In the first position, the airflow in the cavity 111 enters between the movable comb tooth seat 31 and the baffle 100 through the ventilation part 110. The first guide surface 311 guides the airflow from the cavity 111 out of the first air outlet 40 in a direction inclined relative to the top surface of the housing 10. Figure 7 As indicated by the black arrow, this prevents airflow from being blown vertically out of the first air outlet 40 from inside the cavity 111. The first guide surface 311 can be either a sloped surface or a curved surface.

[0062] In some embodiments of this utility model, the inner wall surface of the movable comb tooth seat 31 is provided with a second guide surface 312 near the second air outlet 50. In the second position (not shown in the figure), the airflow in the cavity 111 enters between the movable comb tooth seat 31 and the baffle 100 through the ventilation part 110. The second guide surface 312 guides the airflow from the cavity 111 out of the second air outlet 50 in a direction inclined relative to the top surface of the housing 10, thus preventing the airflow in the cavity 111 from being blown out vertically through the second air outlet 50. The second guide surface 312 can be an inclined surface or an arc surface.

[0063] In some embodiments of this utility model, the inner wall surface of the movable comb tooth seat 31 is provided with a first guide surface 311 near the first air outlet 40 and a second guide surface 312 near the second air outlet 50. Please refer to [link / reference]. Figure 4 , Figure 5 and Figure 7 In the first position, the first guide surface 311 guides a portion of the airflow from the cavity 111 out of the first air outlet 40 in a direction inclined relative to the top surface of the housing 10, such as... Figure 7 As indicated by the black arrow in the middle; the second guide surface 312 guides part of the airflow from the cavity 111 along a direction inclined relative to the top surface of the housing 10, flowing out of the second air outlet 50 and then towards the first air outlet 40, as shown. Figure 7 As indicated by the dashed arrow. In the second position (not shown in the figure), the second guide surface 312 guides part of the airflow from the cavity 111 to the second air outlet 50 in a direction inclined relative to the top surface of the housing 10, and the first guide surface 311 guides part of the airflow from the cavity 111 to the first air outlet 40 and then to the second air outlet 50 in a direction inclined relative to the top surface of the housing 10.

[0064] This is understandable; please refer to [link / reference]. Figure 5 When the movable comb seat 31 is in the first position, the second guide surface 312 of the movable comb seat 31 is closer to the inside of the cavity 111 than the first guide surface 311; while when the movable comb seat 31 is in the second position, its first guide surface 311 is closer to the inside of the cavity 111 than the second guide surface 312.

[0065] The hair straightening comb accessory provided in this embodiment of the utility model rotatably mounts a movable comb tooth base 31 at a first position and a second position at a groove 213. The two sides of the movable comb tooth base 31 in the width direction form a first air outlet 40 and a second air outlet 50 between themselves and the groove wall of the groove 213. The movable comb tooth base 31 assembly can flexibly adjust the airflow direction according to the user's combing direction, allowing the airflow to more precisely align with the hair combing direction. By providing a first guide surface 311 near the first air outlet 40 and / or a second guide surface 312 near the second air outlet 50 on the inner wall of the movable comb tooth base 31, it helps to direct the airflow in the cavity 111 along the first guide surface 311 to the first air outlet 40, or along the second guide surface 312 to the second air outlet 50, preventing the airflow from blowing out vertically, thereby improving the straightness and smoothness of the hair and enhancing the user's combing effect.

[0066] In some embodiments of this utility model, the first guide surface 311 is an arc-shaped surface recessed towards the outer wall surface of the movable comb seat 31, i.e., a concave surface, which has a good drainage effect. In some embodiments of this utility model, the second guide surface 312 is an arc-shaped surface recessed towards the outer wall surface of the movable comb seat 31, i.e., a concave surface, which has a good drainage effect. In yet another embodiment, both the first guide surface 311 and the second guide surface 312 are arc-shaped surfaces recessed towards the outer wall surface of the movable comb seat 31, i.e., concave surfaces, which also have a good drainage effect. It should be noted that the first guide surface 311 and the second guide surface 312 can have the same structure or completely different structures.

[0067] In some embodiments of this utility model, such as Figure 5 As shown, when the movable comb tooth seat 31 drives the movable comb tooth 32 to rotate to the first position, the angle between the tangent of the first guide surface 311 near the first air outlet 40 and the top surface of the housing 10 is C, where 0° < C ≤ 45°, resulting in good air blowing effect. Optionally, C can be 15°, 30°, or 45°.

[0068] In some embodiments of this utility model, when the movable comb tooth seat 31 drives the movable comb tooth 32 to rotate to the second position, the angle between the tangent of the second guide surface 312 near the second air outlet 50 and the top surface of the housing 10 is D, where 0° < D ≤ 45°, resulting in good air blowing effect. Optionally, D can be 15°, 30°, or 45°.

[0069] Please refer to some embodiments of this utility model. Figure 5 The outer wall of the movable comb seat 31 is also provided with a third guide surface 313. The third guide surface 313 is an arc surface that protrudes towards the outside of the cavity 111. It is used to direct the airflow of the first air outlet 40 to the second air outlet 50 through the third guide surface 313, or to direct the airflow of the second air outlet 50 to the first air outlet 40 through the third guide surface 313.

[0070] In one embodiment, the third guide surface 313 covers the first guide surface 311 and the second guide surface 312. In one embodiment, the entire outer wall surface of the movable comb seat 31 is configured as the third guide surface 313, which has a good drainage effect.

[0071] When the movable comb tooth seat 31 drives the movable comb tooth 32 to rotate to the first position, part of the airflow between the baffle 100 and the movable comb tooth seat 31 flows out along the first air outlet 40 under the action of the first guide surface 311. The airflow flowing out from the first air outlet 40 blows out along the hair, and the airflow direction is as follows. Figure 7 As shown by the solid arrow, the airflow passing through the second air outlet 50 flows towards the first air outlet 40 under the action of the third guide surface 313, and then blows out along the hair. The airflow direction is as follows. Figure 7As indicated by the dashed arrow.

[0072] When the movable comb tooth seat 31 drives the movable comb tooth 32 to rotate to the second position, part of the airflow between the baffle 100 and the movable comb tooth seat 31 flows out from the second air outlet 50 under the action of the second guide surface 312, and the airflow flowing out from the second air outlet 50 blows out along the hair. The airflow flowing through the first air outlet 40 flows towards the second air outlet 50 under the action of the third guide surface 313, and then blows out along the hair.

[0073] During the hair combing process, to ensure the hair remains straight and level, the movable comb tooth assembly 30 should not rotate arbitrarily. Therefore, this embodiment of the invention proposes using magnetic adsorption for fixation.

[0074] In some embodiments of this utility model, the hair straightener accessory further includes a first magnetic adsorption member 60 and a second magnetic adsorption member 80. The movable comb tooth seat 31 is provided with the first magnetic adsorption member 60, and the housing 10 or the stop member 100 is provided with the second magnetic adsorption member 80, which can magnetically attract the first magnetic adsorption member 60, so as to position the movable comb tooth seat 31 in the second position. Specifically, the first magnetic adsorption member 60 is provided on the inner wall surface of the movable comb tooth seat 31 near the first air outlet 40; the second magnetic adsorption member 80 is provided on the side of the housing 10 or the stop member 100 near the movable comb tooth seat 31. When the movable comb tooth seat 31 drives the movable comb teeth 32 to rotate to the second position, the first magnetic adsorption member 60 and the second magnetic adsorption member 80 come into contact and are attracted together, thereby fixing the movable comb tooth seat 31 in the second position and preventing it from moving in that direction ( Figure 5 During the hair combing process (in the opposite direction of the indicated movement direction M), the movable comb tooth base 31 rotates. In one embodiment, one of the first magnetic adsorption member 60 and the second magnetic adsorption member 80 is a metal part, and the other is a magnet. In another embodiment, both the first magnetic adsorption member 60 and the second magnetic adsorption member 80 are magnets, and the magnetic poles of the two magnets are opposite.

The movable comb tooth seat 31 is provided with the third magnetic adsorption member 70, and the housing 10 or the stop member 100 is provided with the fourth magnetic adsorption member 90, which can magnetically attract the third magnetic adsorption member 70, so as to position the movable comb tooth seat 31 in a first position. Specifically, the third magnetic adsorption member 70 is provided on the inner wall surface of the movable comb tooth seat 31 near the second air outlet 50; the fourth magnetic adsorption member 90 is provided on the side of the housing 10 or the stop member 100 near the movable comb tooth seat 31. When the movable comb tooth seat 31 drives the movable comb tooth 32 to rotate to the first position, the third magnetic adsorption member 70 and the fourth magnetic adsorption member 90 come into contact and are attracted together, such as... Figure 4 and Figure 5As shown, this fixes the movable comb holder 31 in the first position, preventing it from moving in that direction ( Figure 5 During the hair combing process (as shown in the direction of movement M), the movable comb tooth base 31 rotates. In one embodiment, one of the third magnetic adsorption member 70 and the fourth magnetic adsorption member 90 is a metal part, and the other is a magnet. In another embodiment, both the third magnetic adsorption member 70 and the fourth magnetic adsorption member 90 are magnets, and the magnetic poles of the two magnets are opposite.

[0076] In some embodiments of this utility model, the hair straightener accessory further includes a first magnetic adsorption member 60, a second magnetic adsorption member 80, a third magnetic adsorption member 70, and a fourth magnetic adsorption member 90. The movable comb tooth seat 31 is provided with the first magnetic adsorption member 60, and the housing 10 or the stop member 100 is provided with the second magnetic adsorption member 80, which can magnetically attract with the first magnetic adsorption member 60, so as to position the movable comb tooth seat 31 in a second position; the movable comb tooth seat 31 is provided with the third magnetic adsorption member 70, and the housing 10 or the stop member 100 is provided with the fourth magnetic adsorption member 90, which can magnetically attract with the third magnetic adsorption member 70, so as to position the movable comb tooth seat 31 in a first position.

[0077] This embodiment of the invention uses magnetic adsorption to fix and separate the movable comb tooth seat 31, which is convenient to operate.

[0078] In some embodiments of this utility model, the housing 10 includes a bottom shell having an air inlet 112. In some embodiments, the bottom shell includes an inner housing 11 and an outer housing 12, such as... Figure 1 and Figure 2 As shown, the inner shell 11 is disposed within the outer shell 12, as... Figure 4 and Figure 5 As shown, the inner shell 11 and the fixed comb tooth seat 21 together form a cavity 111, which extends along the axis of the inner shell 11. Figure 9 As shown, the end of the inner housing 11 is provided with an air inlet 112, which communicates with the cavity 111 to ensure smooth airflow. Furthermore, the end of the inner housing 11 is also provided with a mounting portion 113, which is used to connect to the main unit. The main unit communicates with the cavity 111 to provide power to drive the airflow. In one embodiment, the end of the inner housing 11 is provided with a rotating snap-fit ​​structure for connection to the main unit, such as... Figure 9 As shown, the main unit is snapped into the inner casing 11 for easy disassembly and replacement.

[0079] The housing 10 in this embodiment of the present invention also includes a fixed comb tooth assembly 20. The fixed comb tooth assembly 20 includes a fixed comb tooth seat 21 and fixed comb teeth 22. The fixed comb tooth seat 21 is installed on the bottom shell and forms a cavity 111 with the bottom shell. The fixed comb tooth seat 21 is provided with a groove 213. The fixed comb teeth 22 are provided on the fixed comb tooth seat 21 and are located on the outer periphery of the groove 213.

[0080] like Figure 2 and Figure 3 As shown, the fixed comb tooth base 21 has a groove 213, the length direction of which is consistent with the extension direction of the fixed comb tooth base 21. Fixed comb teeth 22 are provided on the fixed comb tooth base 21, located on the outer periphery of the groove 213, ensuring stable fixation of the fixed comb teeth 22 and effective combing of hair during use. The fixed comb tooth base 21 is installed on the bottom shell, such as by snap-fit; the side of the fixed comb tooth base 21 without fixed comb teeth 22 forms a cavity 111 with the bottom shell. In one embodiment, the movable comb tooth assembly 30 is rotatably mounted on the fixed comb tooth base 21, and the movable comb tooth assembly 30 is located at the groove 213.

[0081] In some embodiments of this utility model, the bottom surface of the fixed comb base 21 near the first air outlet 40 is provided with a first inclined surface 211. In the direction from the first air outlet 40 to the movable comb assembly 30, the first inclined surface 211 gradually approaches the outer wall surface of the fixed comb base 21, that is, in the direction from the cavity 111 towards the slot 213, the first inclined surface 211 gradually approaches the outer wall surface of the fixed comb base 21. When the movable comb base 31 is rotated to the second position, the airflow near the first air outlet 40 flows along the first inclined surface 211 to the third guide surface 313, and under the action of the third guide surface 313, flows to the second air outlet 50, and then blows out along the hair. When the movable comb seat 31 is rotated to the first position, the airflow near the first air outlet 40 can flow to the first guide surface 311 under the action of the first inclined surface 211, and is blown out through the first air outlet 40 under the action of the first guide surface 311, which can reduce the airflow from blowing directly vertically out of the first air outlet 40 and improve the straightness of the hair after combing.

[0082] In some embodiments of this utility model, the inner wall surface of the fixed comb tooth seat 21 near the second air outlet 50 is provided with a second inclined surface 212. In the direction from the second air outlet 50 to the movable comb tooth assembly 30, the second inclined surface 212 gradually approaches the outer wall surface of the fixed comb tooth seat 21, that is, in the direction from the cavity 111 towards the slot 213, the second inclined surface 212 gradually approaches the outer wall surface of the fixed comb tooth seat 21. Figure 4 and Figure 5 As shown, when the movable comb base 31 is rotated to the first position, the airflow near the second air outlet 50 flows along the second inclined surface 212 to the third guide surface 313, and under the action of the third guide surface 313, flows to the first air outlet 40, and then blows out along the hair. When the movable comb base 31 is rotated to the second position, the airflow near the second air outlet 50 can flow to the second guide surface 312 under the action of the second inclined surface 212, and then blown out through the second air outlet 50 under the action of the second guide surface 312. This reduces the amount of airflow blowing directly vertically out of the second air outlet 50, improving the straightness of the hair after combing.

[0083] In some embodiments of this utility model, the bottom surface of the fixed comb tooth seat 21 near the first air outlet 40 is provided with a first inclined surface 211. In the direction from the first air outlet 40 to the movable comb tooth assembly 30, the first inclined surface 211 gradually approaches the outer wall surface of the fixed comb tooth seat 21; the inner wall surface of the fixed comb tooth seat 21 near the second air outlet 50 is provided with a second inclined surface 212. In the direction from the second air outlet 50 to the movable comb tooth assembly 30, the second inclined surface 212 gradually approaches the outer wall surface of the fixed comb tooth seat 21.

[0084] In some embodiments of this utility model, the movable comb tooth assembly 30 further includes a rotating shaft 33, which extends along the extending direction of the fixed comb tooth seat 21. Both ends of the rotating shaft 33 are respectively connected to the fixed comb tooth seat 21. The movable comb tooth seat 31 is rotatably connected to the rotating shaft 33, and the movable comb tooth seat 31 can drive the movable comb tooth 32 to rotate around the rotating shaft 33.

[0085] like Figure 5 and Figure 6 As shown, in one embodiment, the bottom surface of the movable comb tooth seat 31 is provided with a groove, the opening of which faces the housing 10. The extending direction of the groove is consistent with the extending direction of the rotating shaft 33. The groove is used to accommodate the rotating shaft 33. Under the action of external force, the movable comb tooth seat 31 can drive the movable comb teeth 32 to rotate around the rotating shaft 33. In some embodiments, in order to prevent the rotating shaft 33 from dislodging from the groove, the bottom surface of the movable comb tooth seat 31 is provided with a limiting member. The two ends of the limiting member are respectively connected to the movable comb tooth seat 31. The limiting member and the groove match to form a receiving space for accommodating the rotating shaft 33. It should be noted that the size of the receiving space is larger than the rotating shaft 33 to facilitate the rotation of the movable comb tooth seat 31. There may be one limiting member, which is provided on the bottom surface of the movable comb tooth seat 31, located in the middle of the length direction, such as... Figure 6 As shown. Multiple limiting members can also be provided, spaced apart along the extending direction of the movable comb seat 31. In one embodiment, three limiting members are provided, respectively disposed on the bottom surface of the movable comb seat 31, located at both ends and the middle in the length direction. The number of limiting members in this embodiment can be set according to the length of the rotating shaft 33.
