[0002] Existing hair styling products have relatively simple functions, so users need to switch products or product accessories to achieve various functional effects. Too many styling tools are not only inconvenient for users to operate, but also take up a lot of storage space, which is not conducive to the user experience. The wind comb products in the prior art usually include comb teeth and multiple air outlets, which can dry the hair during the hair combing process. However, the existing hot air comb products lack the diversified functional options of double-sided air outlet, single-sided air outlet, and styling air outlet. When integrating multiple air outlet functions, how to control the size of the hot air comb body, how to ensure the air outlet effect of each air outlet mode and the air outlet uniformity of the wind comb to improve the styling effect of the wind comb are also technical problems that need to be solved. Summary of the invention

[0006] The combing head further comprises an air outlet, which is provided with a main air outlet. When the air outlet is in the first position, the air guide in the combing head is aligned with the main air outlet to guide the airflow to be discharged from the first air outlet and the second air outlet. The air outlet also has a second position to discharge the airflow from the first air outlet or the second air outlet. When the air outlet is in the first position, the wind pressure of the combing head is P1, and when the air outlet is in the second position, the wind pressure of the combing head is P2, and 50% P2≤P1<P2. Preferably, the longitudinal axis of the two-way air guide is parallel to the longitudinal axis of the main air outlet.

Styling air outlets are provided on both sides of the straight comb tooth assembly, and the air outlet has a third position for discharging air from the styling air outlet. When the air outlet is located at the third position, the air outlet pressure of the comb head is P3, 50% P3≤P2<P3.

[0008] Preferably, the air outlet pressure of the handle assembly is P4, and P3 ≥ 88% P4.

[0009] Preferably, when the air outlet is located at the second position, the air outlet area A of the comb head is larger than the air outlet area B of the handle assembly.

[0010] Preferably, B≤70%A.

[0011] Preferably, the upper comb body assembly and the lower comb body assembly both include a hair-implanted body and comb teeth arranged on the hair-implanted body, and the thickness of the hair-implanted body is d1, 2mm≤d1≤10mm.

[0012] Preferably, the hair implanting body is provided with hair implanting holes for installing comb teeth, and the thickness between the bottom wall of the hair implanting hole and the inner wall of the hair implanting body is d2, 1mm≤d2≤2.5mm.

[0013] Preferably, the comb head also includes a knob for controlling the rotation of the punching bag and a top cover arranged above the punching bag, the knob includes a connecting portion, the top cover is provided with a through hole, the connecting portion extends into the through hole and is connected to the punching bag, the knob also includes a first sealing surface extending outward in a circumferential direction around the connecting portion, a second sealing surface extending outward in a circumferential direction around the axis of the through hole is also provided in the through hole, and a sealing member is sandwiched between the first sealing surface and the second sealing surface.

[0014] Preferably, grooves are provided at the lower ends of the upper comb body assembly and the lower comb body assembly so that when the two are connected, a receiving groove for placing the punching bag can be formed. A groove is provided on the outer wall of the punching bag near one end of the receiving groove, and a sealing member is also provided in the groove.

[0015] Preferably, the straight comb head tooth assembly also includes a two-way flow guide member for guiding the airflow to the styling air outlet, and the two-way flow guide member and the flow guide member are both provided with convex ribs protruding toward the air outlet, and the convex ribs abut against the air outlet and are respectively connected to the upper comb body assembly and the lower comb body assembly to form a mutually independent first air outlet cavity and a second air outlet cavity, the first air outlet cavity is connected to the first air outlet hole, and the second air outlet cavity is connected to the second air outlet hole, and the side of the convex rib contacting the air outlet cylinder includes elastic material.

[0016] The beneficial effects of the utility model are as follows:

[0017] 1. By making the position of the air outlet adjustable, the air can be discharged from different areas of the comb when the air outlet is in different positions, and the air can be discharged from the upper comb tooth assembly, the lower comb tooth assembly, or both, to achieve multi-functions and improve user experience; moreover, when the comb is connected to the host, under the same host working mode, the wind pressure and wind speed are different when the air is discharged from the comb tooth assembly and the lower comb tooth assembly at the same time, and when the air is discharged from one of them respectively, to achieve the switching of the air outlet mode. When the air outlet is in the first position, the wind comb can achieve double-sided air outlet, at which time the air outlet area is the largest and the wind pressure is the lowest, which can meet the needs of users to dry their hair while combing their hair, and also allow users to wrap their hair around the comb and use the double-sided air outlet structure of the wind comb to dry and style their hair, and at this time the wind pressure P1 ≥ 50% P2 to ensure that the airflow blown out by the wind comb still has sufficient wind speed and blowing distance. When the air outlet is in the second position, the wind comb only achieves single-sided air outlet. Compared with the double-sided air outlet mode, this mode has higher wind pressure and wind speed, which makes it easier for users to achieve styling effects such as straight hair through the air comb. In addition, the air comb still has a large air outlet area, which makes it easier for users to handle more hair at the same time. In addition, this product can adjust the air outlet area of ​​the comb by only changing the air outlet, with a simple structure and easy operation.

[0018] 2. The comb also includes a straight comb head tooth assembly arranged opposite to the guide member. The straight comb head tooth assembly can also actively generate heat to style the hair, providing the user with a traditional straight heating mode. Styling air outlets are also provided on both sides of the straight comb head tooth assembly. The air outlet has a third position for discharging air from the styling air outlet, so that the wind comb can also provide the user with a third air outlet mode. When the straight comb head tooth assembly is working, the styling air outlet can either blow air or not. When the styling air outlet blows air, it can blow hot air to assist the straight comb head tooth assembly to heat the hair, or it can blow cold air to quickly cool the hair heated by the straight comb head tooth assembly, thereby improving the styling effect. More specifically, when the air outlet is in the third position, the wind pressure of the airflow discharged from the comb is P3, and P1<P2<P3. The wind pressure of the airflow from the handle assembly to the comb is P4, where P3 ≥ 88% P4. When the air outlet is in the third position, the comb can provide a larger wind pressure. When the styling air outlet is used alone, it is also convenient for users to quickly dry their hair and perform partial styling through the airflow blown out by the comb. By adding a straight comb head tooth assembly and a styling air outlet, users can have more functional options. This product expands the function of the comb, can achieve multiple uses, and improves user experience.

[0019] 3. The thickness of the hair implants of the upper comb body assembly and the lower comb body assembly is set within the range of 2mm-10mm, which can not only ensure that the hair implants have sufficient thickness for installing the comb teeth, but also help to control the overall thickness of the comb body assembly, while ensuring that the comb teeth can be firmly installed, while reducing the size of the comb head. The thickness between the bottom wall of the hair implant holes on the hair implant body and the inner wall of the hair implant body is controlled at 1mm-2.5mm to ensure that the hair implant body has a certain margin when implanting hair. In addition, when the air outlet is in the second position, the air outlet area A of the comb head is greater than the air outlet area B of the handle assembly, and preferably B≤70%A. By controlling the proportional relationship between the air outlet area of ​​the handle assembly and the air outlet area on one side of the comb head, it is beneficial for the air comb to have a larger air outlet area relative to the styling air outlet and appropriate wind pressure and wind speed when the air is discharged from one side, ensuring that the user can achieve a straight hair effect through the single-sided air outlet mode of the air comb. Limiting the size relationship between the air outlet area A of the comb head and the handle assembly B is also beneficial for controlling the size of the comb head and the handle assembly from being too large, thereby facilitating the miniaturization of the entire air comb.

[0020] 4. Since the air bag of this product needs to be rotatably installed in the comb head, the rotation gap formed inside the air comb and the gap caused by tolerance during the installation of the air comb will cause the air comb to leak air and heat. In addition, the present application sets a first sealing surface on the knob that extends outward in the circumferential direction around the connecting part, and forms a second sealing surface in the through hole around the axis of the through hole, so that a seal is sandwiched between the first sealing surface and the second sealing surface. This can ensure that there is a certain rotation gap between the knob and the top cover to prevent the knob from getting stuck when rotating, making it convenient for the user to drive the air bag to rotate by the knob. At the same time, the seal reduces the friction between the knob and the top cover, and prevents hot air from flowing out of the air comb from the gap between the two, thereby reducing the loss of air volume and heat. At the same time, the punching bag will also rotate relative to the accommodating groove, and the punching bag is provided with a groove on the wall close to the accommodating groove, and a seal is also placed in the groove, so that when the air outlet of the handle assembly is connected to the punching bag, the gap between the punching bag and the accommodating groove is no longer prone to air leakage due to the blocking of the seal, which is conducive to allowing the gas to fully enter the punching bag and reduce heat loss and noise problems caused by leakage.

[0021] 5. The straight comb head tooth assembly also includes a two-way flow guide member for guiding the airflow to the styling air outlet. The two-way flow guide member and the flow guide member are connected to the upper comb body assembly and the lower comb body assembly through the convex ribs in contact with the air outlet and respectively form a mutually independent first air outlet cavity and a second air outlet cavity. The first air outlet cavity is connected to the first air outlet hole, and the second air outlet cavity is connected to the second air outlet hole, so that the air outlet is located in the second position, and the airflow will not flow between the first air outlet cavity and the second air outlet cavity, so that the airflow only flows out through one of the first air outlet hole and the second air outlet hole, and when the user selects the single-sided air outlet mode, it can avoid the problem of air leakage on the side that does not blow air. Furthermore, the side of the convex rib contacting the air outlet includes elastic material, so that the air outlet can rotate relative to the convex rib, avoid the air outlet from getting stuck, and improve the working reliability of the wind comb.

[0036] The contents of the present invention are described in detail below through specific implementation modes.

[0037] like Figure 1-12 As shown, the utility model provides a wind comb 1, comprising a comb head 2, a handle assembly 3 connected to the comb head 2, and the handle assembly 3 generally comprises an air inlet 31, a fan unit and a heater arranged inside the handle assembly 3, and an air outlet 32. The heater is located downstream of the fan unit, and when the fan unit is working, the external airflow enters the inside of the handle assembly 3 from the air inlet 31, is discharged from the air outlet 32 ​​after being heated by the heater, and enters the inside of the comb head 2 through the airflow inlet.

[0038] The combing head 2 includes an air flow inlet and multiple air flow outlets for receiving air flow, and the air flow is discharged through the multiple air flow outlets and acts on the user's hair; the combing head 2 includes an upper comb body assembly 21 and a lower comb body assembly 22, and the multiple air flow outlets include a first air outlet 211 located in the upper comb body assembly 21 and a second air outlet 221 located in the lower comb body assembly 22; wherein, the combing head 2 also includes an air outlet cylinder 23 located between the upper comb body assembly 21 and the lower comb body assembly 22, and the air outlet cylinder 23 is provided with a main air outlet 231 arranged along the longitudinal axis of the combing head 2, and a guide member 24 is fixedly provided at the connection between the upper comb body assembly 21 and the lower comb body assembly 22, and the guide member 24 is also arranged along the longitudinal axis of the combing head 2, and when the air outlet cylinder 23 rotates to the first position, the main air outlet 231 is aligned with the guide member 24 to guide the air flow to be discharged from the first air outlet 211 and the second air outlet 221. At this time, the length of the guide 24 is set to be greater than the length of the main air outlet 231, so as to ensure that the guide 24 can fully guide the airflow blown out of the main air outlet 231 to the first air outlet 211 and the second air outlet 221 on both sides. Along the axial direction of the combing head 2, the distance between the guide 24 and the main air outlet 231 is constant, and the airflow volume and time received by the guide 24 at different positions in the longitudinal direction are basically the same, so that the first air outlet 211 and the second air outlet 221 located at different positions in the axial direction of the combing head 2 can discharge air at the same time, thereby improving the uniformity of the air outlet. Specifically, the length ratio of the guide 24 to the main air outlet 231 is preferably set in the range of 1.05 to 1.3, so that the guiding effect of the guide 24 on the airflow can be ensured, and the volume of the wind comb 1 can be prevented from increasing due to the excessive length of the guide 24, which is conducive to the miniaturization of the machine.

[0039] like Figure 5-6 As shown, the guide member 24 includes a raised portion 243 located in the middle and a first guide arc surface 241 and a second guide arc surface 242 located on both sides of the raised portion 243. The first guide arc surface 241 and the second guide arc surface 242 are connected so that the cross section of the guide member 24 is in an "M" shape. When the air outlet tube 23 is located in the first position, the raised portion 243 of the guide member 24 is aligned with the longitudinal axis of the main air outlet 231, which is convenient for equally dividing the air flow blown out from the main air outlet 231, which helps to make the air flow of the upper comb body assembly 21 and the lower comb body assembly 22 the same. The air flow from the main air outlet 231 is guided by two guide arc surfaces to improve the air outlet uniformity.

[0040] The guide member 24 has a first edge line and a second edge line, and the first edge line and the second edge line are respectively located on both sides of the main air outlet 231; the first edge line is projected along a direction perpendicular to the axis of the air outlet cylinder 23 to form a first projection line, and the second edge line is projected along a direction perpendicular to the axis of the air outlet cylinder 23 to form a second projection line; the first edge line and the first projection line are connected to form a first virtual plane located between the air outlet cylinder 23 and the guide member 24; the second edge line and the second projection line are connected to form a second virtual plane located between the air outlet cylinder 23 and the guide member 24; the area of ​​the first virtual plane is S1, and the area of ​​the second virtual plane is S2, 0.8≤S1 / S2≤1.2, by making the air outlet area formed by the guide member 24 and the two sides of the air outlet cylinder have similar sizes, it is beneficial to make the airflow derived from the two sides of the guide member 24 have approximately the same wind speed and wind pressure, thereby improving the uniformity of the air outlet on both sides of the wind comb 1. It can be understood that the preferred value of S1 / S2 is 1.

[0041] The area of ​​the main air outlet 231 is S, 0.5≤(S1+S2) / S≤1.2. By setting the ratio of (S1+S2) to S, the guide 24 can be controlled to adjust the wind speed and wind pressure of the airflow blown out of the air outlet 23 within a certain range, so as to ensure that the air outlet at the upper comb body assembly 21 and the lower comb body assembly 22 has appropriate wind speed and wind pressure when the air outlet 23 is in the first position, which is beneficial for the guide 24 to guide the airflow to the opposite side of the guide 24, avoiding excessive concentration of the air outlet of the wind comb 1 on the side close to the main air outlet 231, and is beneficial for improving the uniformity of the air outlet of the upper comb body assembly 21 and the lower comb body assembly 22. More specifically, 360mm 2 ≤S1+S2≤760mm 2 By setting the specific size of (S1+S2), it is beneficial to further control the adjustment effect of the airflow blown out of the air outlet 23 by the air guide 24, which can avoid the airflow being too low due to the large area, and the airflow being difficult to blow to the far end of the air outlet hole, which is beneficial to ensure that the combing head 2 can have sufficient airflow in the circumferential direction, improve the airflow uniformity of the air comb 1, and prevent the airflow from passing through a small area and causing excessive air volume loss. By adjusting the size of (S1+S2), the air guide 24 can achieve the effect of taking into account both air volume and wind speed, and while ensuring the uniform airflow of the air comb 1, it is also beneficial to maintain a certain ideal wind speed after the airflow is blown out from the air comb 1, and ensure the hair drying and styling effect of the air comb 1 when the air is discharged from both sides. In this example, S1+S2 is preferably 560mm².

[0042] like Figure 6As shown, the distance between the first edge line and the first projection line is L1, 1.5mm≤L1≤6mm. Such a setting is conducive to ensuring that there is a suitable distance between the guide member 24 and the air outlet 23, so as to form a reasonable air flow passing area between the two, and at the same time, it can also avoid that the distance between the guide member 24 and the air outlet 23 is too large, which affects the overall volume of the wind comb 1. Setting the distance between the second edge line and the second projection line to L2, and making L2=L1, is conducive to the guide member 24 to evenly guide the airflow to the air outlet holes on both sides, thereby improving the air outlet uniformity of the wind comb 1. Furthermore, the curvature radii of the first guide arc surface 241 and the second guide arc surface 242 are also set to be equal, which is also beneficial to improving the uniformity of air outlet. The ratio of the curvature radius of the first guide arc surface 241 to its arc length is within the range of 0.4 to 1.2, and the curvature radius of the first guide arc surface 241 is R, 8mm≤R≤40mm. By controlling the curvature of the guide arc surface, the guide member 24 can effectively guide the airflow to the air outlet holes on both sides of the main air outlet 231, so as to ensure that when the air outlet tube 23 is in the first position, the air outlet surfaces on both sides thereof can have sufficient airflow.

[0043] Furthermore, when the air outlet 23 is in the first position, the air velocity discharged from the main air outlet 231 is V1, which is set in the range of 38m / s to 43m / s. The air velocity after the airflow passes through the guide member 24 is V2, and V2 ≥ 70% V1, which is conducive to making the airflow passing through the guide member 24 have sufficient wind speed to run to the air outlet position farthest from the guide member 24, so as to ensure the air volume and air uniformity of the wind comb 1 in the circumferential direction. In this example, V1 is preferably 40m / s.

[0044] The present application achieves the effect of the combing head 2 being able to blow air on both sides of the upper comb body assembly 21 and the lower comb body assembly 22 by setting up the guide member 24, and through the specific structural design of the guide member 24 and the specific matching relationship between the guide member 24 and the air outlet tube 23, the air comb 1 has a better air outlet effect when the combing head 2 blows air on both sides, thereby improving the user experience when using the double-sided air outlet mode.

[0045] like Figure 1-9As shown, in order to further meet the user's needs for different functions, the air outlet 23 also includes a second position that allows only one of the upper comb body assembly 21 and the lower comb body assembly 22 to discharge air, providing the user with another air outlet area and wind speed. In addition, the comb 2 also includes a straight comb head tooth assembly 25 arranged opposite to the guide member 24. The straight comb head tooth assembly 25 can also actively generate heat to style the hair. Styling air outlets 26 are also provided on both sides of the straight comb head tooth assembly 25. The air outlet 23 has a third position for the air flow to be discharged from the styling air outlet 26, so that the wind comb 1 can also provide the user with a third air outlet mode, and when the straight comb head tooth assembly 25 is working, the styling air outlet 26 can either discharge air or not, and when the styling air outlet 26 is discharging air, it can either discharge hot air to assist the straight comb head tooth assembly 25 in heating the hair, or blow cold air to quickly cool the hair heated by the straight comb head tooth assembly 25, thereby improving the styling effect. By adding the straight comb head tooth assembly 25 and the styling air outlet 26, the user can have more functional options. This product expands the functions of the wind comb 1, enabling one machine to have multiple uses and improving user experience.

[0046] Specifically, when the air outlet 23 is in the first position, the wind pressure of the airflow discharged from the combing head 2 is P1; when the air outlet 23 is in the second position, the wind pressure of the airflow discharged from the combing head 2 is P2; when the air outlet 23 is in the third position, the wind pressure of the airflow discharged from the combing head 2 is P3, where P1<P2<P3. The wind pressure of the airflow blown from the handle assembly 3 to the combing head 2 is P4, where P3≥88%P4. Furthermore, when the air outlet 23 is in the third position, the wind comb 1 can provide a large wind pressure, which is convenient for the user to quickly dry the hair and perform partial styling through the airflow blown out of the styling air outlet 26. When the air outlet 23 is in the second position, one of the upper comb body assembly 21 and the lower comb body assembly 22 discharges air, and has a larger air outlet area relative to the styling air outlet 26, so that the wind comb 1 can act on more hair, and at this time P2≥50%P3, so that the wind comb 1 also has a large wind speed, and the user can achieve a better straight hair effect through the wind comb 1. When the air outlet 23 is in the first position, the air outlet area is the largest and the wind pressure is the lowest, which can meet the user's needs of combing hair and drying hair with soft wind. It can also allow the user to wrap the hair around the comb 2 and use the air outlet effect on both sides of the comb 2 to dry and style the hair. P1 ≥ 50% P2 is conducive to ensuring that the air comb 1 still has sufficient air volume and air outlet distance to meet the above-mentioned hair drying and styling needs when it is at the lowest wind pressure. In this example, the preferred values ​​of wind pressure are: P1 = 11g, P2 = 21g, P3 = 40g, P4 = 44g. This product forms three levels of wind pressure with obvious differences in the three wind outlet modes, thereby providing users with a variety of choices with differentiated hair-drying effects, so that users can meet different styling needs through different wind speeds and wind pressures.

[0047] The upper comb body assembly 21 and the lower comb body assembly 22 both include a hair implant body and comb teeth arranged on the hair implant body, and the thickness of the hair implant body is d1, 2mm≤d1≤10mm. This can not only ensure that the hair implant body has sufficient thickness for installing the comb teeth, but also help to control the overall thickness of the comb body assembly, while ensuring that the comb teeth can be firmly installed, while reducing the size of the comb head 2. The hair implant body is provided with a hair implant hole 201 for installing the comb teeth, and the thickness between the bottom wall of the hair implant hole 201 and the inner wall of the hair implant body is d2, 1mm≤d2≤2.5mm, to ensure that the hair implant body has a certain margin when implanting hair.

[0048] Furthermore, the diameter of the air outlet 23 is set to d, 22mm≤d≤28mm, and when the air outlet 23 is in the second position, the air outlet area A of the combing head 2 is greater than the air outlet area B of the handle assembly 3, and preferably B≤70%A. By controlling the proportional relationship between the air outlet area on one side of the combing head 2 and the air outlet area of ​​the handle assembly 3, it is beneficial to enable the air comb 1 to have a larger air outlet area and appropriate wind pressure and wind speed relative to the styling air outlet 26 when the air is discharged from one side, so that the user can achieve a straight hair effect through the single-sided air outlet mode of the air comb 1. By limiting the diameter of the air outlet 23, the wind pressure and air volume of the main air outlet can also be controlled, thereby ensuring that each air outlet on the combing head 2 has an ideal air outlet effect. At the same time, by limiting the diameter of the air outlet 23 and the size of the air outlet areas A and B, it is also beneficial to control the size of the combing head 2 and the handle assembly 3 so that it will not be too large, which is convenient for the overall miniaturization of the air comb 1.

[0049] Based on the design purpose of this product for multiple uses, the air outlet 23 needs to be rotatably installed in the comb head 2. The rotation gap formed inside the wind comb 1 and the gap caused by tolerance during the installation of the wind comb 1 will cause the wind comb 1 to have air leakage and heat leakage problems. Figure 10-11As shown, in this example, the comb head 2 also includes a knob 27 for controlling the rotation of the punching bag 23 and a top cover 28 arranged above the punching bag 23, the knob 27 includes a connecting portion 271 for connecting to the punching bag 23, the top cover 28 is provided with a through hole 281 allowing the connecting portion 271 to pass through, the connecting portion 271 of the knob 27 extends into the through hole 281 and forms a connection with the punching bag 23. Furthermore, the knob 27 also includes a first sealing surface 272 extending outwardly in the circumferential direction around the connecting portion 271, and a part of the wall surface of the through hole 281 is recessed and a second sealing surface 282 extending outwardly in the circumferential direction around the axis of the through hole 281 is formed in the through hole 281, and a sealing member is sandwiched between the first sealing surface 272 and the second sealing surface 282. Such a configuration can ensure that there is a certain rotation gap between the knob 27 and the top cover 28 to prevent the knob 27 from getting stuck when rotating, and at the same time, the friction between the knob 27 and the top cover 28 is reduced by the sealing member, and the hot air is prevented from flowing out of the wind comb 1 from the gap between the two, thereby reducing the loss of air volume and heat. In this example, a sealing ring with a thickness of 0.8 mm is preferably used between the first sealing surface 272 and the second sealing surface 282.

[0050] like Fig.12 As shown, the lower ends of the upper comb body assembly 21 and the lower comb body assembly 22 are provided with grooves, and when the two are buckled together, a receiving groove for placing the air outlet 23 is formed. The air outlet 23 is close to one end of the receiving groove, and its end outer wall surface is provided with a groove 232, and a seal is also placed in the groove 232. Then, when the air outlet 32 ​​of the handle assembly 3 is connected to the air outlet 23, the gap between the air outlet 23 and the receiving groove is no longer prone to air leakage due to the obstruction of the seal, which is conducive to allowing the gas to fully enter the air outlet 23 and reduce the heat loss and noise caused by air leakage. In this example, the seal in the groove 232 preferably uses a sealing ring with a thickness of 1 mm.

[0051] like Figure 4 and 8As shown, the straight comb head tooth assembly 25 also includes a two-way guide member 251 for guiding the airflow to the styling air outlet 26. The two-way guide member 251 and the guide member 24 are both provided with a convex rib 2510 protruding toward the air outlet tube 23. In this example, the convex rib 2510 of the guide member 24 is the above-mentioned protruding portion 243. The convex rib 2510 abuts against the air outlet tube 23 and is respectively connected to the upper comb body assembly 21 and the lower comb body assembly 22 to form a mutually independent first air outlet cavity 212 and a second air outlet cavity 222. The first air outlet cavity 212 is connected to the first air outlet hole 211, and the second air outlet cavity 222 is connected to the second air outlet hole 221, so that the air outlet tube 23 is located in the second position, and the airflow will not circulate between the first air outlet cavity 212 and the second air outlet cavity 222, so that the airflow can flow out only through one of the first air outlet hole 211 and the second air outlet hole 221, so that when the user selects the single-sided air outlet mode, the air leakage problem on the side where no air is discharged can be avoided. Furthermore, the side of the rib 2510 contacting the air outlet 23 includes elastic material, so that the air outlet 23 can rotate relative to the rib 2510, thereby preventing the air outlet 23 from getting stuck and improving the working reliability of the air comb 1.
