[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 combs have internal guides to allow the airflow entering the comb to flow out from multiple air outlets. However, the existing guides still have the defect that the air volume at the bottom of the comb is less than that at the top of the comb, resulting in uneven air flow.

[0025] The beneficial effects of the utility model are as follows:

[0026] 1. By making the position of the air outlet adjustable, air can be discharged from different areas of the combing head when it is in different positions, that is, when it is in different positions, air can be discharged from the upper comb body assembly, the lower comb body assembly, or both, thereby achieving multi-functions and improving user experience; moreover, when the combing head is connected to the host, under the same host working mode, when air is discharged from the comb tooth assembly and the lower comb body assembly at the same time, and when air is discharged from either of them separately, the wind pressure and wind speed are different, thereby achieving switching of the air outlet mode.

[0027] Furthermore, the air outlet area of ​​the combing hair can be adjusted by only changing the air outlet, which has a simple structure and is easy to operate.

[0028] By arranging the two-way air guide along the longitudinal axis of the combing head and aligning the two-way air guide with the main air outlet, the uniformity of the air outlet of the first air outlet and the second air outlet arranged along the axis of the combing head is improved, even if the air outlet of the upper and lower parts of the combing head is basically the same. More specifically, the airflow entering the combing head first enters the air outlet cylinder, and blows toward the two-way air guide from the main air outlet arranged on the side thereof, and the two-way air guide is guided by the two-way air guide to be discharged from the first air outlet and the second air outlet. Different from the existing combing head air duct structure, this method can improve the uniformity of the air outlet of the first air outlet and the second air outlet, and solves the problem that the airflow is blown out from the air outlet near the upper part, while the air outlet at the lower part of the combing head blows out a small amount of airflow or even no airflow in the existing solution.

[0029] 2. By making the longitudinal axis of the two-way air guide parallel to the longitudinal axis of the main air outlet, when the air outlet is in the first position, along the axial direction of the comb head, the distance between the two-way air guide and the main air outlet is constant, and the air flow rate and time received by the two-way air guide at different positions in the longitudinal direction are basically the same, so that the first air outlet and the second air outlet located at different positions in the axial direction of the comb head can discharge air at the same time, thereby improving the uniformity of air outlet.

[0030] 3. The two-way air guide is symmetrically arranged about its longitudinal axis, and the upper comb body assembly and the lower comb body assembly are symmetrically arranged about the longitudinal axis of the comb head, which can further improve the uniformity of air outlet from the first air outlet and the second air outlet; and at the same time, make the air outlet uniformity of the upper comb body assembly and the lower comb body assembly the same.

[0031] 4. By aligning the middle raised portion with the longitudinal axis of the main air outlet, it helps to equally divide the amount of air blown out from the main air outlet, so that the air output of the upper comb body assembly and the lower comb body assembly is the same; the air flow from the main air outlet is guided by the arc-shaped air guide plate to improve the uniformity of the air output.

[0032] 5. By forming independent first air outlet cavity and second air outlet cavity inside the combing head, the airflows of the first air outlet cavity and the second air outlet cavity do not interfere with each other, thereby reducing noise.

[0033] 6. By setting air outlet holes on the two-way air guide, the air flow is discharged from the first air outlet hole and the second air outlet hole through the air outlet holes, so that corresponding air outlet holes can also be set in the overlapping areas of the upper comb body assembly, the lower comb body assembly and the two-way air guide, thereby increasing the air volume and improving the air outlet efficiency.

[0034] 7. By making the first air outlet group correspond to the first hole group and the second air outlet group correspond to the second hole group, airflow is blown out from both the first hole group and the second hole group, and the airflow is blown out along a preset trajectory, thereby improving the uniformity of air outlet along the longitudinal axis of the comb head.

[0035] 8. By providing an air guide portion protruding toward the air outlet, and the air guide portion is provided corresponding to the main air outlet, when the air outlet is located at the second position, the air flow blown out from the main air outlet first passes through the air guide portion, and the air flow is guided to both sides under the action of the air guide portion, thereby improving the uniformity of the single-sided air outlet.

[0036] 9. By making the air guide portion include a tip and a first guide slope extending from the tip to both sides, and the tip is aligned with the axis of the main air outlet, the airflow from the main air outlet is evenly divided and then blown to both sides under the guidance of the first guide slope, which can further improve the uniformity of air outlet.

[0037] 10. When 0.5mm≤D≤20mm, it can ensure the uniformity of the air outlet of the comb when the air outlet is located at the first position and the second position respectively, and at the same time ensure the air outlet volume of the comb and make the comb have a smaller volume; when D<0.5mm, too small a distance will cause the air volume to be suppressed and the air cannot be discharged efficiently; it will also cause the tip to block the airflow when the air outlet is in the first position, resulting in uneven air outlet on both sides; when D>20mm, the comb will be large in size, turbulence will be more easily formed, noise will increase, and air volume will decrease.

[0038] 11. By making the air inlet area of ​​the first hole position smaller than the air inlet areas of the second hole position and the third hole position, that is, the air inlet area of ​​the hole position close to the air guide portion is smaller than the air inlet area of ​​the hole position far from the air guide portion, the advantage is that when the air outlet is in the second position, the air outlet uniformity of the first hole position, the second hole position and the third hole position is improved, and the air volume of the first hole position is prevented from being significantly higher than that of other holes.

[0039] 12. By setting the second guide slope, the air output of the first hole is increased when the air outlet is located at the first position, thereby improving the uniformity of air output.

[0040] 13. When the air outlet is located at the first position, the first wind shielding rib is set to block the airflow, so that the airflow changes its path under the action of the first wind shielding rib, and the airflow flows to the first hole position and the third hole position, so that the airflow also flows out from the first hole position and the third hole position away from the two-way air guide component, and the airflow outflow from the second hole position close to the two-way air guide component is reduced, thereby improving the uniformity of air outlet.

[0041] 14. When the air outlet is in the first position, the third guide slope guides the airflow to be discharged from the third hole. When the air outlet is in the second position, the third guide slope accelerates the airflow to be discharged from the third hole, thereby improving the air outlet efficiency and further improving the air outlet uniformity of the first air outlet.

[0042] 15. Through the arrangement of the second hole group and the air guiding part, the airflow in different areas of the comb head can be guided separately to improve the uniformity of air outlet. More specifically, when the air outlet is located at the first position, the air guiding part guides the airflow guided by the two-way air guide for a second time, and guides the airflow into the fifth hole position away from the two-way air guide, so that air can also be discharged from the air outlet holes away from the two-way air guide, thereby improving the uniformity of circumferential air outlet; when the air outlet is located at the second position, the air guiding part guides the airflow from the main air outlet to the fourth hole position and the fifth hole position, thereby improving the uniformity of circumferential air outlet.

[0043] 16. When the air outlet is located at the first position, the fourth guide slope is set to block the airflow discharged from the fourth hole position, and the blocked airflow continues to flow along the plane part, and reaches the fifth guide slope after being guided by the plane part, so that the airflow is discharged from the fifth hole position, thereby ensuring that the fourth and fifth holes have a certain air outlet; when the air outlet is located at the second position, the plane part guides the airflow from the main air outlet to the fourth guide slope and the fifth guide slope, so that the airflow is discharged from the fourth and fifth holes.

[0044] 17. By setting up the hair straightening comb tooth assembly, the comb has multiple functions and the user experience is improved; by setting up styling air outlets on both sides of the hair straightening comb tooth assembly and allowing the air flow to be discharged from the styling air outlets, the function of the hair comb is expanded and the user experience is improved.

[0045] 18. By setting the air guide cover, an independent air outlet cavity which is respectively connected to the first air outlet hole and the second air outlet hole is formed in the comb head, thereby reducing the noise caused by turbulence; further, by setting the first air guide arc surface and the second air guide arc surface, the eddy current is reduced, thereby reducing the air volume loss and making the air outlet more uniform.

DETAILED DESCRIPTION

[0059] The contents of the present invention are described in detail below through specific implementation modes.

[0060] Embodiment 1

[0061] like Figures 1 to 10 As shown, a multifunctional comb head 00 comprises an airflow inlet 1 for receiving airflow; a plurality of airflow outlets 15 through which airflow is discharged; an upper comb body assembly 2 and a lower comb body assembly 3, wherein the plurality of airflow outlets 15 comprise a first air outlet 4 located in the upper comb body assembly 11, and a second air outlet 5 located in the lower comb body assembly 3,

[0062] The comb head 00 further comprises an air outlet 6, on which a main air outlet 601 is arranged along the longitudinal axis of the comb head 00, and a two-way air guide 7 is fixedly provided at the connection between the upper comb body assembly 2 and the lower comb body assembly 3, and the two-way air guide 7 is arranged along the longitudinal axis of the comb head 00, as shown in FIG. Figure 3 , 4 As shown, when the air outlet pipe 6 is in the first position, the main air outlet 601 is aligned with the two-way air guide 7, and the air is discharged from the first air outlet 4 and the second air outlet 5. When the air outlet pipe 6 is in the second position, the main air outlet 601 is aligned with the first air outlet 4, and the air is discharged from the first air outlet 4.

[0063] It can be understood that when the air outlet 6 is located at the second position, the main air outlet 601 is aligned with the second air outlet 5 , and the air flow is discharged from the second air outlet 5 .

[0064] like Fig.12 As shown, the comb head 00 of the utility model is used to connect with a host 01 capable of generating airflow, and the host 01 generally includes an air inlet, a fan unit and a heater arranged inside the host, and an air outlet. The heater is located downstream of the fan unit. When the fan unit is working, the external airflow enters the host 01 from the air inlet, and is discharged from the air outlet after being heated by the heater. The hot airflow enters the comb head 00 through the airflow inlet 1.

[0065] The user can control the position of the punching bag 6 as needed. More specifically, the combing head 00 also includes an operating knob 21 located at the end of the combing head 00. The operating knob 21 is fixedly connected to the punching bag 6, preferably by screws. Twisting the operating knob 21 can drive the punching bag 6 to rotate, thereby achieving position switching. In order to stabilize the air flow, the position of the punching bag 6 needs to be locked, so a position locking structure of the punching bag 6 is provided on the combing head 00.

[0066] like Figure 5As shown, the upper comb body assembly 2 also includes a first bristle body 201 for setting bristles and soft-rubber comb teeth, and a first air outlet 4 is arranged on the first bristle body 201; the lower comb body assembly 3 also includes a second bristle body 301 for setting bristles and soft-rubber comb teeth, and a second air outlet 5 is arranged on the second bristle body 301. The first bristle body 201 and the second bristle body 301 are connected by screws; one of the first bristle body 201 and the second bristle body 301 is provided with a groove extending along the length direction of the comb head 00, and the other is provided with a rib matching the aforementioned groove, which plays a positioning role and facilitates the rapid assembly of the first bristle body 201 and the second bristle body 301. Furthermore, the comb head 00 also includes a protective aluminum cover (not shown in the figure) sleeved on the outside of the first bristle body 201 and the second bristle body 301, and the protective aluminum cover is provided with the same hole position as the first bristle body 201 and the second bristle body 301 to facilitate the airflow to blow out and the bristles and soft-rubber comb teeth to pass through. As shown Figure 3 , 4 As shown in Figures 5 and 6, a positioning protrusion 22 is provided above the first hair implant 201 or the second hair implant 301, and a buckle position 704 cooperating with the positioning protrusion 22 is provided on the two-way flow guide 7, which is convenient for quick assembly of the two-way flow guide 7. A convex rib 705 is provided on one side of the inner side wall of the two-way flow guide 7 close to the first hair implant 201 and the second hair implant 301, and the convex rib 705 has two ribs, which respectively abut against the inner side wall of the first hair implant 201 and the second hair implant 301, further improving the assembly stability of the two-way flow guide 7.

[0067] The longitudinal axis of the two-way air guide 7 is parallel to the longitudinal axis of the main air outlet 601. When the air outlet cylinder 6 is located at the first position, along the axial direction of the combing head 00, the distance between the two-way air guide 7 and the main air outlet 601 is constant, and the air flow and time received by the two-way air guide 7 at different positions in the longitudinal direction are basically the same, so that the first air outlet 4 and the second air outlet 5 at different positions in the axial direction of the combing head 00 can discharge air at the same time, thereby improving the uniformity of air discharge.

[0068] Furthermore, the two-way air guide 7 is symmetrically arranged about its longitudinal axis, and the upper comb body assembly 2 and the lower comb body assembly 3 are symmetrically arranged about the longitudinal axis of the comb head 00. The uniformity of air outlet from the first air outlet 4 and the second air outlet 5 can be further improved, and the uniformity of air outlet from the upper comb body assembly 2 and the lower comb body assembly 3 is made the same.

[0069] More specifically, Fig.11As shown, the two-way air guide 7 includes a central protrusion 701 and arc-shaped air guide plates 702 located on both sides of the central protrusion 701. When the air outlet tube 6 is in the first position, the central protrusion 701 of the two-way air guide 7 is aligned with the longitudinal axis of the main air outlet 601. In this example, the cross-section of the two-way air guide 7 is in an "M" shape. By aligning the central protrusion 701 with the longitudinal axis of the main air outlet 601, it is helpful to divide the air flow blown out from the main air outlet 601 equally, so that the air flow of the upper comb body assembly 2 and the lower comb body assembly 3 is the same; the air flow from the main air outlet 601 is guided by the arc-shaped air guide plate 702 to improve the uniformity of the air flow.

[0070] In one example, the comb head 00 is further provided with a partition wall (not shown in the figure) between the upper comb body assembly 2 and the lower comb body assembly 3, the partition wall abuts against the air outlet tube 6, the middle raised portion 701 abuts against the air outlet tube 6 to form a first air outlet cavity 8 and a second air outlet cavity 9 that are independent of each other inside the comb head 00, the main air outlet 601 includes a first main port 6011 and a second main port 6012 and are respectively located on both sides of the middle raised portion 701, the first air outlet cavity 8 is connected with the first main port 6011 and the first air outlet hole 4, and the second air outlet cavity 9 is connected with the second main port 6012 and the second air outlet hole 5. By making the first air outlet cavity 8 and the second air outlet cavity 9 independent of each other, the airflows of the first air outlet cavity 8 and the second air outlet cavity 9 do not interfere with each other, thereby reducing noise and improving the concentration and uniformity of the single-sided air outlet.

[0071] Understandable, such as Figure 2-7 Another example is shown, the combing head 00 further includes a hair straightening combing tooth assembly 18, the hair straightening combing tooth assembly 18 is respectively connected to the upper combing body assembly 2 and the lower combing body assembly 3, the hair straightening combing tooth assembly 18 is arranged opposite to the two-way air guide 7, and the two sides of the hair straightening combing tooth assembly 18 are provided with styling air outlets 23, and the air outlet 6 has a third position for the air flow to be discharged from the styling air outlet 23, so as to expand the function of the combing head 00, realize one machine with multiple uses, and improve the user experience. When the hair straightening combing tooth assembly 18 is working, the styling air outlet 23 can or cannot discharge air.

[0072] Furthermore, the hair straightening comb tooth assembly 18 includes an air guide cover 1801, and the air guide cover 1801 is in contact with the outer wall of the air outlet tube 6. The air guide cover 1801, the air outlet tube 6, the upper comb body assembly 2, and the lower comb body assembly 3 form an air outlet cavity, and the air guide cover 1801 has a first air guide arc surface 19 facing the upper comb body assembly 2 and a second air guide arc surface 20 facing the lower comb body assembly 3. More specifically, the first air guide arc surface 19 and the second air guide arc surface 20 have the same curvature with a maximum curvature of 0.2, which can guide the airflow and have a good air guiding effect, reduce the possibility of the airflow being squeezed and forming vortices here to affect the air outlet, and improve the air outlet uniformity. In this example, when the air outlet tube 6 is in the third position, the main air outlet 601 is located in the first air guide arc surface 19 and the second air guide arc surface 20 to ensure that the airflow is discharged from the styling air outlet 23. Figure 4 , 8 -10, the inner wall of the upper comb body assembly 2 is provided with a plurality of air guides 10 which are arranged at intervals along the longitudinal axis direction of the comb head 00 and protrude toward the air outlet 6. In the second position, the air guide 10 is arranged corresponding to the main air outlet 601. It can be understood that the lower comb body assembly 3 is also provided with the same air guide 10, which guides the airflow from the main air outlet 601 to both sides to improve the uniformity of the single-sided air outlet. Furthermore, the air guide 10 has a tip 103 close to the air outlet 6, and a first guide slope 101 extending from the tip 103 to both sides. The tip 103 is aligned with the axis of the main air outlet 601 to further improve the uniformity of the single-sided air outlet. More specifically, the air guide 10 is arranged on the inner walls of the first hair implant 201 and the second hair implant 301. When the air outlet 6 is located at the first position, the distance between the position on the air outlet 6 that is directly opposite to the tip 103 and the tip 103 is D, 0.5mm≤D≤20mm, which can ensure the uniformity of the air outlet of the comb head when the air outlet 103 is located at the first position and the second position respectively, and at the same time ensure the air outlet volume of the comb head 00 and make the comb head 00 have a smaller volume; when D<0.5mm, too small a distance will cause the air volume to be suppressed and the air cannot be discharged efficiently; it will also cause the tip 103 to block the airflow when the air outlet 6 is located at the first position, resulting in uneven air outlet on both sides; when D>20mm, the comb head 00 will be large in volume, turbulence will be more easily formed, noise will increase, and air volume will be reduced. Preferably, D=1.4mm.

[0073] The first air outlet hole 4 includes a plurality of first hole groups 401 spaced apart along the longitudinal axis direction of the combing head 00, the first hole group 401 includes a first hole position 4011, and a second hole position 4012 and a third hole position 4013 located on both sides of the first hole position 4011, the first hole position 4011 and the air guide portion 10 are alternately arranged, the second hole position 4012 is close to the two-way flow guide 7, and the air inlet area of ​​the first hole position 4011 is smaller than the air inlet area of ​​the second hole position 4012 and the third hole position 4013. That is, the air inlet area of ​​the hole position close to the air guide portion 10 is smaller than the air inlet area of ​​the hole position far from the air guide portion 10, and the advantage is that when the air outlet tube 6 is in the second position or the third position, the air outlet uniformity of the first hole position 4011, the second hole position 4012, and the third hole position 4013 is improved, and the air volume of the first hole position 4011 is prevented from being significantly higher than that of other holes.

[0074] The upper end and / or lower end of the air guide portion 10 is provided with a second guide slope 102, and the second guide slope 102 extends upward from a position close to the two-way guide member 7 to a direction close to the first hole position 4011, thereby increasing the air output of the first hole position 4011 when the air outlet pipe 6 is in the first position and improving the uniformity of the air output.

[0075] The first wind shielding rib 11 is disposed on one side of the second hole 4012 close to the two-way air guide 7. When the air outlet is located at the first position, the first wind shielding rib 11 blocks the airflow, so that the airflow changes its path under the action of the first wind shielding rib 11, and flows to the first hole 4011 and the third hole 4013, so that the airflow also flows out from the first hole 4011 and the third hole 4013 away from the two-way air guide 7, and the outflow of the airflow from the second hole 4012 close to the two-way air guide 7 is reduced, thereby improving the uniformity of air outlet.

[0076] The air inlet end of the third hole position 4013 has a third guide slope 12 extending outward from a position close to the first hole position 4011 to a direction away from the two-way guide member 7.

[0077] The first air outlet 4 also includes a plurality of second hole groups 402 spaced apart along the longitudinal axis direction of the combing head 00, the first hole group 401 and the second hole group 402 are alternately arranged, the second hole group 402 includes a fourth hole position 4021 and a fifth hole position 4022 arranged laterally, an air induction portion 17 is provided between the fourth hole position 4021 and the fifth hole position 4022, and the air induction portion 17 and the air guide portion 10 are alternately arranged along the longitudinal axis direction of the combing head 00. Through the arrangement of the second hole group 402 and the air induction portion 17, the airflows in different areas on the comb head 00 are guided separately to improve the uniformity of air outlet. More specifically, when the air outlet cylinder 6 is located at the first position, the air induction portion 17 performs secondary air induction on the airflow guided by the two-way flow guide 7 to guide the airflow into the fifth hole position 4022 away from the two-way flow guide 7, so that airflow is also discharged from the air outlet holes away from the two-way flow guide 7, thereby improving the uniformity of circumferential air outlet; when the air outlet cylinder 6 is located at the second position and the third position, the air induction portion 17 guides the airflow from the main air outlet to the fourth hole position 4021 and the fifth hole position 4022, thereby improving the uniformity of circumferential air outlet.

[0078] The air guide portion 17 includes a plane portion 16, a fourth guide slope 13 and a fifth guide slope 14 located on both sides of the plane portion 16, the fourth guide slope 13 extends outward from one side of the plane portion 16 toward the direction close to the fourth hole position 4021, and the fifth guide slope 14 extends outward from the other side of the plane portion 16 toward the direction close to the fifth hole position 4022. When the air outlet pipe 6 is located in the first position, the fourth guide slope 13 is set to block the air flow discharged from the fourth hole position 4021, and the blocked airflow continues to flow along the plane portion 16, and reaches the fifth guide slope 14 under the guidance of the plane portion 16, so that the airflow is discharged from the fifth hole position 4022, thereby ensuring that the fourth hole position 4021 and the fifth hole position 4022 have a certain air outlet; when the air outlet pipe 6 is located in the second position or the third position, the plane portion 16 guides the airflow from the main air outlet to the fourth guide slope 13 and the fifth guide slope 14, so that the airflow is discharged from the fourth hole position 4021 and the fifth hole position 4022.

[0079] When the air outlet cylinder 6 is located at the second position, the middle protrusion 701 abuts against the side wall of the air outlet cylinder 6 to ensure the air volume and uniformity of the single-sided air outlet.

[0082] Further, the air outlet holes 703 include a first air outlet group 7031 and a second air outlet group 7032 arranged alternately along the axial direction of the two-way air guide 7; along the longitudinal axial direction of the combing head 00, the first air outlet holes 4 include a first hole group 401 and a second hole group 402 arranged alternately, the airflow discharged from the first air outlet group 7031 is discharged from the first hole group 401, and the airflow discharged from the second air outlet group 7032 is discharged from the second hole group 402. By the first air outlet group 7031 corresponding to the first hole group 401 and the second air outlet group 7032 corresponding to the second hole group 402, the first hole group 401 and the second hole group 402 are both blown out with airflow, and the airflow is blown out along a preset trajectory, thereby improving the uniformity of the airflow of the combing head 00 along its longitudinal axial direction. More specifically, the structures of the upper comb body assembly 2 and the lower comb body assembly 3 are the same as those of Example 1; the composition of the first hole group 401 and the second hole group 402 is the same as that of Example 1. The hole positions of the first air outlet group 7031 correspond one-to-one to the hole positions of the first hole group 401 , and the hole positions of the second air outlet group 7032 correspond one-to-one to the hole positions of the second hole group 402 .

[0083] Through the technical solution provided by the utility model, the air outlet uniformity of the combing head 00 can be guaranteed when the air outlet tube 6 is located at different positions.
