Technical Field
[0001] The utility model relates to the field of hair care electrical appliances, in particular to an air guide component for an air comb. Background Art
[0002] With the improvement of people's living standards, hair care appliances have become a daily necessity for modern people. Hair care appliances include hair dryers, hair styling tools and other products. Such products usually include a heating unit and a fan unit. The fan unit allows external airflow to enter the hair dryer, which is heated by the heating unit and then discharged as hot air. The hot air acts on the hair to dry the hair and style the hair. For wind comb products, which include comb teeth and multiple air outlets, the hair can be dried while combing.
[0003] Existing hot air comb products lack diversified functional options such as double-sided air outlet, single-sided air outlet, and styling air outlet. In addition, although the guide piece set inside the existing hot air comb products has the effect of guiding the airflow to multiple air outlets, it still has the defect of uneven air outlet. Therefore, how to achieve double-sided air outlet of the hot air comb and achieve air outlet uniformity when double-sided air outlet is a technical problem that needs to be solved. Summary of the invention

[0005] The technical solution of the utility model is as follows:

[0008] Preferably, 360 mm 2 ≤S1+S2≤760mm 2 .
[0009] Preferably, the area of the main air outlet is S, 0.5≤(S1+S2) / S≤1.2.

[0011] Preferably, the distance between the second edge line and the second projection line is L2, and L2=L1.
[0012] Preferably, the first guide arc surface and the second guide arc surface have the same curvature radius, and the ratio of the curvature radius of the first guide arc surface to its arc length is in the range of 0.4 to 1.2.
[0013] Preferably, the radius of curvature of the first guide arc surface is R, 8mm≤R≤40mm.
[0014] Preferably, the diameter of the punching tube is d, 22mm≤d≤28mm.
[0015] Preferably, the wind speed of the airflow discharged from the main air outlet is V1, and the wind speed of the airflow after being guided by the guide member is V2, and V2 ≥ 70% V1.
[0016] The beneficial effects of the utility model are as follows:
[0017] 1. The guide member includes a first guide arc surface and a second guide arc surface, and the first guide arc surface and the second guide arc surface are connected and form an "M" shape on the transverse section, and the connection between the two protrudes toward the main air outlet, and then when the main air outlet is aligned with the guide member, the guide member can guide the airflow blown out of the main air outlet to both sides, so that the wind comb of the wind guide assembly provided by the present application can achieve the effect of double-sided wind outlet. Furthermore, at this time, the length of the guide member is set to be greater than the length of the main air outlet to ensure that the guide member can fully guide the airflow blown out of the main air outlet. At this time, the length ratio of the guide member to the air outlet is preferably set in the range of 1.05 to 1.3, which can not only ensure the guiding effect of the guide member on the airflow, but also avoid the increase in the volume of the wind comb due to the excessive length of the guide member, which is conducive to the miniaturization of the machine.
[0018] 2. The air guide 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; the first edge line is projected along a direction perpendicular to the axis of the air outlet to form a first projection line, and the second edge line is projected along a direction perpendicular to the axis of the air outlet 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 and the air guide; the second edge line and the second projection line are connected to form a second virtual plane located between the air outlet and the air guide; by controlling the ratio of the area S1 of the first virtual plane to the area S2 of the second virtual plane within a range of 0.8-1.2, the air guide and the two sides of the air outlet are formed to have similar sizes, which is beneficial for the airflow derived from the two sides of the air guide to have approximately the same wind speed and wind pressure, thereby improving the air outlet uniformity of the air guide component.
[0019] 3. The area of the main air outlet is S, 0.5≤(S1+S2) / S≤1.2. By setting the ratio of (S1+S2) to S, the guide can be controlled to adjust the wind speed and wind pressure of the airflow blown out of the air outlet within an appropriate range to ensure that the airflow exported to both sides by the air guide component has an appropriate wind speed and wind pressure, which is conducive to the airflow being able to fully flow to the opposite side of the guide component, avoiding the air outlet of the wind comb being excessively concentrated on the side close to the main air outlet, which is conducive to the air guide effect of the air guide component and the air outlet uniformity of the wind comb using the air guide component. Further, the size of (S1+S2) is set at 360mm. 2 -760mm 2, which is conducive to further controlling the adjustment effect of the guide member on the airflow blown out of the air outlet, can avoid the air speed being too low due to too large an area, and the air flow being difficult to blow to the side away from the main air outlet, which is conducive to ensuring that the air comb can have sufficient airflow in the circumferential direction, improving the air outlet uniformity of the air comb, and at the same time preventing the air flow from passing through an area that is too small and causing excessive air volume loss. By adjusting the size of (S1+S2), the air guide component can achieve the effect of taking into account both air volume and wind speed, and the air guide component is conducive to ensuring the uniform air outlet of the air comb, and is also conducive to maintaining a certain ideal wind speed after the air flow is blown out from the air comb, so as to ensure the hair drying and styling effects of the air comb when the air is discharged from both sides.
[0020] 4. The distance L1 between the first edge line and the first projection line is set within the range of 1.5mm-6mm, which is conducive to ensuring that there is an appropriate distance between the guide member and the air outlet, so as to form a reasonable airflow passage area between the two, and at the same time, it can also avoid the distance between the guide member and the air outlet being too large, which affects the overall volume of the air guide component and the wind comb. 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 to evenly guide the airflow to the air outlet holes on both sides, thereby improving the uniformity of the air outlet of the wind comb. At the same time, the diameter d of the air outlet is set to 22mm-28mm, which is conducive to controlling the wind speed and pressure at the main air outlet, limiting the size of the air guide component, and miniaturizing the wind comb.
[0021] 5. Setting the curvature radius of the first guide arc surface and the second guide arc surface to be equal is beneficial to improving the uniformity of air outlet. The ratio of the curvature radius of the first guide arc surface to its arc length is set in the range of 0.4 to 1.2, and the curvature radius of the first guide arc surface is set to R, 8mm≤R≤40mm. By controlling the curvature of the guide arc surface, the guide member can effectively guide the airflow to the air outlet holes on both sides of the main air outlet to ensure that when the wind comb discharges air on both sides, there is sufficient airflow on the air outlet surface.
[0022] 6. The wind speed of the airflow discharged from the main air outlet is V1, and the wind speed of the airflow after passing through the guide member is V2, V2 ≥ 70% V1. By adjusting the wind comb that guides the airflow out of the guide member, it is beneficial to make the airflow passing through the guide member have sufficient wind speed, so that it can run to the air outlet position far away from the guide member, and have an ideal blowing distance and wind pressure after blowing out the wind comb, thereby ensuring the air volume and air uniformity of the wind comb in the circumferential direction.

[0037] The contents of the present invention are described in detail below through specific implementation modes.
[0038] 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.
[0039] 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.
[0040] 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.
[0041] 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.
[0042] 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.
[0043] 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.
[0044] 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.
[0045] 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.
[0046] 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.
[0047] 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 gears of wind pressure with obvious differences in the three wind outlet modes, thereby providing users with a variety of choices with differentiated blow-drying effects, so that users can meet different styling needs through different wind speeds and wind pressures.
[0048] 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.
[0049] 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.
[0050] 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.
[0051] 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.
[0052] 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.
