[0004] 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 and hair styling tools. These products typically include a heating unit and a fan unit. The fan unit allows external air to enter the hair dryer, where it is heated by the heating unit and then discharged as hot air. The hot air acts on the hair to dry and style the hair. For hair combs, these products include comb teeth and multiple air outlets, allowing them to dry the hair while combing.

[0005] Existing hot air comb products are equipped with an internal guide to allow the airflow entering the comb head to flow out from multiple air outlets. The specific structure is to set multiple blades facing the air outlets along the axial direction of the comb head. However, there is still a defect that the air output at the bottom of the comb head is less than the air output at the upper part of the comb head, resulting in uneven air output. How to achieve uniform air output from multiple air outlets is a technical problem that needs to be solved.

The beneficial effects of the present disclosure are as follows:

[0027] 1. By arranging a 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 airflow from the first and second air outlets arranged along the combing head axis is improved, even if the airflow from the upper and lower parts of the combing head is substantially the same. More specifically, the airflow entering the combing head first enters the air outlet cylinder and is blown from the main air outlet located on its side toward the two-way air guide. The two-way air guide guides the airflow and discharges it from the first and second air outlets. Unlike existing combing head air duct structures, this method can improve the uniformity of airflow from the first and second air outlets, solving the problem in existing solutions where airflow is blown out from the air outlet near the top, while the air outlet at the bottom of the combing head blows out a small amount of airflow or even no airflow.

[0028] 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 tube is in the first position, the distance between the two-way air guide and the main air outlet is constant along the axial direction of the comb head, 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.

[0029] 2. 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; at the same time, the air outlet uniformity of the upper comb body assembly and the lower comb body assembly is the same.

[0030] 3. By aligning the middle raised portion with the longitudinal axis of the main air outlet, it helps to equally divide the air flow 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.

[0031] 4. By forming independent first and second air outlet cavities inside the combing head, the airflows of the first and second air outlet cavities do not interfere with each other, thereby reducing noise.

[0032] 5. 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.

[0033] 6. 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 output from the combing head along its longitudinal axis.

[0034] 7. 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, or the lower comb body assembly, or from the upper comb body assembly and the lower comb body assembly at the same time, 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 from one of them separately, the wind pressure and wind speed are different, thereby achieving switching of the air outlet mode and improving user experience.

[0035] Furthermore, 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 in the second position, the air flow blown out from the main air outlet first passes through the air guide portion, and under the action of the air guide portion, the air flow is guided to both sides, thereby improving the uniformity of the single-sided air outlet.

[0036] 8. By making the air guide portion include a tip and a first guide slope extending from the tip to both sides, and aligning the tip 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 the air outlet.

[0037] 9. When 0.5mm≤D≤20mm, it can ensure the uniformity of the air outlet of the combing head when the air outlet is respectively in the first position and the second position, and at the same time ensure the air outlet volume of the combing head and make the combing head have a smaller volume; when D<0.5mm, the too small distance will cause the air volume to be suppressed and the air cannot be discharged efficiently; it will also cause the tip of the air outlet 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 combing head will be larger in volume, turbulence will be more likely to form, noise will increase, and air volume will decrease.

[0038] 10. By making the air inlet area of ​​the first hole position smaller than the air inlet areas of the second and third hole positions, 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 or the third position, the air outlet uniformity of the first, second and third hole positions is improved, preventing the air volume of the first hole position from being significantly higher than that of other holes.

[0039] 11. 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 the air output.

[0040] 12. When the air outlet is in the first position, the airflow is blocked by the setting of the first wind shield rib, so that the airflow changes its route under the action of the first wind shield rib, and the airflow flows to the first hole position and the third hole position, so that airflow also flows out from the first hole position and the third hole position away from the two-way air guide component, reducing the airflow outflow from the second hole position close to the two-way air guide component, and improving the uniformity of the air outlet.

[0041] 13. When the air outlet is in the first position, the setting of the third guide slope guides the airflow to be discharged from the third hole position. When the air outlet is in the second position or the third position, the third guide slope accelerates the airflow to be discharged from the third hole position, thereby improving the air outlet efficiency and further improving the air outlet uniformity of the first air outlet.

[0042] 14. Through the arrangement of the second hole group and the air induction part, the airflow in different areas of the comb head can be guided separately to improve the uniformity of the air outlet. More specifically, when the air outlet is located at the first position, the air induction 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 the air outlet holes away from the two-way air guide also have airflow discharged, thereby improving the uniformity of the circumferential air outlet; when the air outlet is located at the second position and the third position, the air induction part guides the airflow from the main air outlet to the fourth hole position and the fifth hole position, thereby improving the uniformity of the circumferential air outlet.

[0043] 15. When the air outlet is in the first position, the fourth guide slope is set to block the air flow discharged from the fourth hole position, and the blocked air flow continues to flow along the plane part, and reaches the fifth guide slope after being guided by the plane part, so that the air flow is discharged from the fifth hole position, thereby ensuring that the fourth and fifth hole positions have a certain air outlet volume; when the air outlet is in the second position or the third position, the plane part guides the air flow from the main air outlet to the fourth guide slope and the fifth guide slope, so that the air flow is discharged from the fourth and fifth hole positions.

[0044] 16. By providing a straightening comb assembly, the comb has multiple functions, improving the user experience; by providing styling vents on both sides of the straightening comb assembly and allowing air to be discharged from the styling vents, the function of the comb is expanded and the user experience is improved.

[0045] 17. By setting the air guide cover, an independent air outlet cavity is formed in the comb head, which is connected to the first air outlet hole and the second air outlet hole respectively, 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.

[0059] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0060] The contents of the present disclosure are described in detail below through specific implementation methods.

[0061] Example 1:

[0062] As shown in Figures 1 to 10, a multifunctional combing head 00 includes an airflow inlet 1 for receiving airflow; a plurality of airflow outlets 15, through which the airflow is discharged; an upper comb body assembly 2 and a lower comb body assembly 3, wherein the plurality of airflow outlets 15 include a first air outlet 4 located on the upper comb body assembly 11 and a second air outlet 5 located on the lower comb body assembly 3.

[0063] Among them, the combing head 00 also includes an air outlet 6, which is provided with a main air outlet 601 arranged along the longitudinal axis of the combing 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. The two-way air guide 7 is arranged along the longitudinal axis of the combing head 00. As shown in Figures 3 and 4, when the air outlet 6 is in the first position, the main air outlet 601 is aligned with the two-way air guide 7, and the air flow is discharged from the first air outlet 4 and the second air outlet 5. When the air outlet 6 is in the second position, the main air outlet 601 is aligned with the first air outlet 4, and the air flow is discharged from the first air outlet 4.

[0064] It is understandable that when the air outlet 6 is in 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. As shown in Figure 12, the comb head 00 described in the present disclosure is used to be connected to a host 01 capable of generating airflow. The host 01 generally includes an air inlet, a fan unit and a heater provided inside the host, and an air outlet. The heater is located downstream of the fan unit. When the fan unit is working, the external air flow enters the interior of the host 01 from the air inlet, and is heated by the heater and discharged from the air outlet. The hot air flow enters the interior of the comb head 00 through the air 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 ensure stable air flow, the position of the punching bag 6 needs to be locked. Therefore, a position locking structure for the punching bag 6 is provided on the combing head 00.

[0066] As shown in Figure 5, the upper comb body assembly 2 also includes a first bristle implant 201 for arranging bristles and soft-rubber comb teeth, and a first air outlet 4 is provided on the first bristle implant 201; the lower comb body assembly 3 also includes a second bristle implant 301 for arranging bristles and soft-rubber comb teeth, and a second air outlet 5 is provided on the second bristle implant 301. The first bristle implant 201 and the second bristle implant 301 are connected by screws; one of the first bristle implant 201 and the second bristle implant 301 is provided with a groove extending along the length direction of the comb head 00, and the other is provided with a rib that cooperates with the aforementioned groove, which plays a positioning role and facilitates the rapid assembly of the first bristle implant 201 and the second bristle implant 301. Furthermore, the comb head 00 also includes a protective aluminum cover (not shown in the figure) that is sleeved on the outside of the first bristle implant 201 and the second bristle implant 301. The protective aluminum cover is provided with the same hole position as the first bristle implant 201 and the second bristle implant 301 to facilitate the air flow to blow out and the bristles and soft-rubber comb teeth to pass through. As shown in Figures 3, 4, 5, and 6, a positioning protrusion 22 is provided above the first bristle implant 201 or the second bristle implant 301, and a buckle position 704 that cooperates with the positioning protrusion 22 is provided on the two-way flow guide 7, which facilitates the rapid assembly of the two-way flow guide 7. A rib 705 is provided on one side of the inner side wall of the two-way flow guide 7 close to the first bristle implant 201 and the second bristle implant 301. The rib 705 has two ribs, which respectively abut against the inner side wall of the first bristle implant 201 and the second bristle 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 in the first position, the distance between the two-way air guide 7 and the main air outlet 601 is constant along the axis of the combing head 00. The two-way air guide 7 receives substantially the same amount of airflow and for the same duration at different longitudinal positions, thereby allowing the first air outlet 4 and the second air outlet 5 located at different axial positions of the combing head 00 to discharge air simultaneously, improving air uniformity.

[0068] Furthermore, the two-way air guide 7 is symmetrically arranged about its longitudinal axis, and the upper comb assembly 2 and the lower comb assembly 3 are symmetrically arranged about the longitudinal axis of the comb head 00. This can further improve the uniformity of airflow from the first air outlet 4 and the second air outlet 5, while ensuring that the airflow uniformity of the upper comb assembly 2 and the lower comb assembly 3 is the same.

[0069] More specifically, as shown in Figure 3, the two-way air guide 7 includes a central raised portion 701 and curved air guide plates 702 located on either side of the central raised portion 701. When the air outlet 6 is in the first position, the central raised portion 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 M-shaped. Aligning the central raised portion 701 with the longitudinal axis of the main air outlet 601 helps to evenly divide the airflow from the main air outlet 601, ensuring that the airflow from the upper comb assembly 2 and the lower comb assembly 3 is the same. The curved air guide plates 702 guide the airflow from the main air outlet 601, improving airflow uniformity.

[0070] The comb head 00 is also provided with a partition wall 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 central raised portion 701 abuts against the air outlet tube 6 to form a first air outlet chamber 8 and a second air outlet chamber 9 within the comb head 00 that are independent of each other. The main air outlet 601 includes a first main port 6011 and a second main port 6012, which are located on either side of the central raised portion 701. The first air outlet chamber 8 communicates with the first main port 6011 and the first air outlet hole 4, and the second air outlet chamber 9 communicates with the second main port 6012 and the second air outlet hole 5. By making the first air outlet chamber 8 and the second air outlet chamber 9 independent of each other, the airflows in the first air outlet chamber 8 and the second air outlet chamber 9 do not interfere with each other, reducing noise while also improving the concentration and uniformity of the single-sided air outlet.

[0071] As can be understood, as shown in another example in Figures 2-7, the comb head 00 further includes a straightening comb assembly 18, which is connected to the upper comb body assembly 2 and the lower comb body assembly 3, respectively. The straightening comb assembly 18 is disposed opposite the two-way air guide 7. Styling air vents 23 are provided on both sides of the straightening comb assembly 18, and the air outlet 6 has a third position for discharging air from the styling air vents 23. This expands the functionality of the comb head 00, achieving multi-purpose use and improving the user experience. When the straightening comb assembly 18 is in operation, the styling air vents 23 can either discharge air or not.

[0072] Furthermore, the hair straightening comb assembly 18 includes an air guide cover 1801, which abuts against the outer wall of the air outlet 6. The air guide cover 1801, the air outlet 6, the upper comb assembly 2, and the lower comb assembly 3 form an air outlet cavity. The air guide cover has a first air guide arc surface 19 facing the upper comb assembly 2 and a second air guide arc surface 20 facing the lower comb 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, achieve good air guiding effects, reduce the possibility of the airflow being squeezed and forming vortices here, and affect the air output, and improve the uniformity of the air output. In this example, when the air outlet 6 is in the third position, the main air outlet 601 is located within 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.

[0073] As shown in Figures 4, 8-10, the inner wall of the upper comb body assembly 2 is provided with a plurality of air guides 10 that are spaced apart along the longitudinal axis of the comb head 00 and protrude toward the air outlet 6. In the second position, the air guide 10 is provided corresponding to the main air outlet 601. It is understandable 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, thereby improving 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, thereby further improving the uniformity of the single-sided air outlet. More specifically, the air guide 10 is provided on the inner wall of the first bristle implant 201 and the second bristle implant 301. When the air outlet 6 is in 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, and 0.5mm≤D≤20mm can ensure the uniformity of the air outlet of the combing head when the air outlet 103 is in the first position and the second position, while ensuring the air output of the combing head 00 and making the combing head 00 have a smaller volume. When D is less than 0.5mm, the too small distance will cause the air volume to be suppressed, and the air cannot be efficiently discharged. In addition, when the air outlet 6 is in the first position, the tip 103 will block the airflow, resulting in uneven air output on both sides. When D is greater than 20mm, the combing head 00 will be larger, more likely to form turbulence, resulting in increased noise and reduced air volume. Preferably, D = 1.4mm.

[0074] The first air outlet holes 4 include a plurality of first hole groups 401 spaced apart along the longitudinal axis of the combing head 00. The first hole groups 401 include a first hole position 4011, and second and third hole positions 4012 and 4013 located on either side of the first hole position 4011. The first hole positions 4011 are arranged alternately with the air guide portion 10, and the second hole positions 4012 are located near the two-way flow guide 7. The air inlet area of ​​the first hole positions 4011 is smaller than the air inlet areas of the second and third hole positions 4012 and 4013. In other words, the air inlet area of ​​the holes located near the air guide portion 10 is smaller than the air inlet area of ​​the holes located farther from the air guide portion 10. This has the advantage that, when the air outlet tube 6 is in the second or third position, the air outlet uniformity of the first, second, and third hole positions 4011, 4012, and 4013 is improved, preventing the air volume of the first hole position 4011 from being significantly higher than that of the other holes.

[0075] 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 expanding the air outlet of the first hole position 4011 when the air outlet pipe 6 is in the first position, thereby improving the uniformity of the air outlet.

[0076] A first wind shielding rib 11 is provided on a side of the second hole 4012 near the two-way air guide 7. When the air outlet is in the first position, the first wind shielding rib 11 blocks the airflow, causing the airflow to change its path under the action of the first wind shielding rib 11, directing the airflow toward the first hole 4011 and the third hole 4013. This also allows air to flow out from the first hole 4011 and the third hole 4013 away from the two-way air guide 7, reducing the amount of air outflow from the second hole 4012 near the two-way air guide 7 and improving air outlet uniformity.

[0077] The air inlet end of the third hole 4013 has a third guide slope 12 extending outward from a position close to the first hole 4011 to a direction away from the two-way guide member 7.

[0078] The first air outlet 4 also includes a plurality of second hole groups 402 spaced apart along the longitudinal axis 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. The air induction portion 17 and the air guide portion 10 are alternately arranged along the longitudinal axis of the combing head 00. Through the arrangement of the second hole group 402 and the air induction part 17, the airflow in different areas of the comb head 00 can be guided separately to improve the uniformity of the air outlet. More specifically, when the air outlet cylinder 6 is located in the first position, the air induction part 17 guides the airflow guided by the two-way flow guide 7 for a second time, and guides the airflow into the fifth hole position 4022 away from the two-way flow guide 7, so that the air outlet holes away from the two-way flow guide 7 also have airflow discharged, thereby improving the uniformity of the circumferential air outlet; when the air outlet cylinder 6 is located in the second position and the third position, the air induction part 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 the circumferential air outlet.

[0079] The air induction portion 17 includes a planar portion 16, a fourth guide slope 13 and a fifth guide slope 14 located on both sides of the planar portion 16, the fourth guide slope 13 extends outward from one side of the planar 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 planar portion 16 toward the direction close to the fifth hole position 4022. When the air outlet 6 is 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 air flow continues to flow along the plane portion 16, and reaches the fifth guide slope 14 after being guided by the plane portion 16, so that the air flow 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 6 is in the second position or the third position, the plane portion 16 guides the air flow from the main air outlet to the fourth guide slope 13 and the fifth guide slope 14, so that the air flow is discharged from the fourth hole position 4021 and the fifth hole position 4022.

[0080] 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 flow and uniformity of the single-sided air outlet.

[0081] Example 2:

[0082] The difference between this embodiment and embodiment 1 is that, as shown in Figure 11, the two-way air guide 7 is provided with an air outlet hole 703, and part of the air flow discharged from the main air outlet is discharged to the first air outlet hole 4 and the second air outlet hole 5 through the air outlet hole 703; by providing the air outlet hole 703 on the two-way air guide 7, the air flow is discharged from the first air outlet hole 4 and the second air outlet hole 5 through the air outlet hole 703, so that the corresponding air outlet holes 703 can also be provided in the overlapping areas of the upper comb body assembly 2, the lower comb body assembly 3 and the two-way air guide 7, thereby increasing the air volume and improving the air outlet efficiency.

[0083] Furthermore, the air outlet holes 703 include a first air outlet group 7031 and a second air outlet group 7032, arranged alternately along the axis of the two-way air guide 7. Along the longitudinal axis 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. Airflow from the first air outlet group 7031 is discharged from the first hole group 401, and airflow from the second air outlet group 7032 is discharged from the second hole group 402. With 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, airflow is blown out from both the first hole group 401 and the second hole group 402, and the airflow is blown out along a predetermined trajectory, thereby improving the uniformity of airflow along the longitudinal axis of the combing head 00. More specifically, the construction of the upper comb body assembly 2 and the lower comb body assembly 3 is the same as in Example 1; the composition of the first hole group 401 and the second hole group 402 is the same as in Example 1. The hole positions of the first air outlet group 7031 correspond one-to-one with the hole positions of the first hole group 401 , and the hole positions of the second air outlet group 7032 correspond one-to-one with the hole positions of the second hole group 402 .

[0084] Through the technical solution provided by the present disclosure, the air outlet uniformity of the combing head 00 can be guaranteed when the air outlet tube 6 is located at different positions.
