[0031] As part of the creative concept of the present application, before describing the embodiments of the present application, it is necessary to analyze the causes of the problems of long preheating time and poor heating effect when using air combs in related technologies, and obtain the technical solution of the embodiments of the present application through reasonable analysis.

[0032] In the related technology, hot air is generated during the use of an air comb, and heat is mainly generated by the PTC heating element. The motor generates airflow, which drives the airflow to blow through the PTC heating element, heating the airflow to generate hot air, and then the hot air flows into the air comb head to heat the heating element of the air comb head, generally the comb teeth of the air comb head, so that the effect of high-temperature heating and straightening the hair can be achieved during the combing process. The material of the comb teeth is generally metal materials such as aluminum and aluminum alloy to maintain a good heat transfer effect.

[0033] However, during the use of current air combs, the airflow remains in a flowing state passing through the comb teeth, and preheating requires a long time, resulting in a poor heating effect, resulting in a poor user experience.

[0034] To this end, the present application provides an air combing head, thereby solving the technical problems of long preheating time and poor heating effect of air combing heads in the prior art.

[0035] The technical solutions of the embodiments of the present application are described in detail below in conjunction with the accompanying drawings. The technical features involved in the different implementation modes of the present application described below can be combined with each other as long as there is no conflict between them.

[0036] refer to Figure 1 In an embodiment of the present application, an air combing head is provided, which includes a shell 1. The shell 1 serves as the overall structural basis of the air combing head structure, and its specific shape can be adjusted according to actual needs; in addition, referring to Figure 2 and Figure 3 The air comb head also includes a wind tube 2 arranged in the shell 1 and a comb tooth assembly arranged on the wind tube 2.

[0037] Among them, the air duct 2 is provided with an air inlet channel 21, the comb tooth assembly is provided with an air inlet 31, an air outlet 32 ​​and a ventilation channel 6 located in the comb tooth assembly, and the air inlet 31 is connected to the air inlet channel 21. The ventilation channel 6 is divided into a first channel 61 and a second channel 62 that are connected to each other, the end of the first channel 61 away from the second channel 62 is the first end, the end of the second channel 62 away from the first channel 61 is the second end, and the end where the first channel 61 and the second channel 62 are connected is the connecting end. Among them, the first end is connected to the air inlet 31, and the second end is connected to the air outlet 32. A flow path of the air inlet channel 21-air inlet 31-first channel 61-second channel 62-air outlet 32 ​​is formed. Exemplarily, the ventilation channel 6 is V-shaped.

[0038] A drainage channel 51 is also provided in the comb tooth assembly, and the drainage channel 51 connects the first flow channel 61 and the second flow channel 62. The end of the drainage channel 51 connected to the first flow channel 61 is located between the first end and the connecting end, and the end of the drainage channel 51 connected to the second flow channel 62 is located between the second end and the connecting end.

[0039] On the one hand, the first flow channel 61 and the second flow channel 62 are connected through the connecting end to form a V-shaped ventilation flow channel 6; on the other hand, the first flow channel 61 and the second flow channel 62 are also connected through the drainage channel 51, forming two passages from the air inlet 31 to the air outlet 32.

[0040] In this way, during use, the airflow is transmitted along the path of air inlet channel 21-air inlet 31-first flow channel 61-second flow channel 62-air outlet 32. At the same time, a part of the airflow is diverted to the drainage channel 51 during transmission in the first flow channel 61, and is transported from the drainage channel 51 to the second flow channel 62, and then converges with the airflow directly transported from the first flow channel 61 to the second flow channel 62 and is transmitted to the air outlet 32.

[0041] By setting the drainage channel 51, a Tesla valve-like reverse flow channel is formed. The Tesla valve reverse flow channel is two air flow channels that are close to colliding in the forward direction. The present application forms a structure similar to the Tesla valve reverse flow channel through the drainage channel 51; the airflows converge in the second flow channel 62, and when converging, the airflows collide with each other and generate heat by friction, and the kinetic energy of the airflow is converted into thermal energy. Compared with the prior art where the airflow is directly transmitted along the ventilation channel 6 and flows through the toothed shell 42, the heat generated in the toothed shell 42 is increased, the preheating time is shortened, the heating effect is improved, and the user experience is better.

[0042] On the other hand, during use of the existing combing head structure, the further back the position is on the air flow transmission path, the lower the temperature is, so that the heating efficiency and temperature of the corresponding position of the air combing head are also lower. By setting the drainage channel 51, the temperature of the second flow channel 62 close to the air outlet 32 ​​end, that is, the temperature of the rear position on the air flow transmission path, can be increased, which can improve the uniformity of the temperature at different positions of the air combing head to a certain extent.

[0043] Specifically, the comb tooth assembly includes an air guide structure 3 connected to the air cylinder 2 , a comb tooth structure 4 and inner teeth 5 .

[0044] The air duct 2 is arranged in the housing 1 and fixedly connected to the housing 1. The two can be fixedly connected by clamping or bonding. An air inlet channel 21 is arranged inside the air duct 2. When in use, one end of the air inlet channel 21 is connected to the structure for generating hot air, so that the hot air is transported to the air inlet channel 21. The cross-sectional shape of the air duct 2 can be set to a polygon such as a rectangle or a pentagon, or a circle, an ellipse or other irregular shapes. In the embodiment of the present application, the cross-sectional shape of the air duct 2 is only taken as an example, which means that the inner circle and the outer circle of the cross-sectional shape of the air duct 2 are both circular.

[0045] The wind guide structure 3 is arranged on the wind tube 2. The embodiment of the present application is explained by taking the integral molding of the two as an example. Of course, in other embodiments, the two can also be set as separate structures and connected by means of snap-on, bonding, hot-melt connection, bolt fixing, etc.

[0046] The air inlet 31 and the air outlet 32 ​​are arranged on the air guide structure 3, and the air inlet 31 and the air outlet 32 ​​are not connected to each other; the air inlet 31 and the air outlet 32 ​​are not connected to each other here, which means that the two are in an independent state in the air guide structure 3, and are not directly connected, but may be connected through another structure. Among them, the air inlet 31 is connected to the air inlet channel 21.

[0047] The comb tooth structure 4 is connected to the air guide structure 3, and the comb tooth structure 4 includes a bracket 41 and a plurality of tooth-shaped shells 42 arranged on the bracket 41; the bracket 41 is fixedly connected to the air guide structure 3, and similarly, the connection method can be different methods such as snap connection, bonding, and hot-melt connection; the cavity inside the tooth-shaped shell 42 is connected to the air inlet 31 and the air outlet 32, so that the airflow in the air inlet channel 21 is transported to the tooth-shaped shell 42 through the air inlet 31, and discharged from the air outlet 32. In addition to the above-mentioned transmission path, the tooth-shaped shell 42 maintains a sealed connection with other connected positions of the air guide structure 3. Correspondingly, the number of air inlets 31 is the same as the number of tooth-shaped shells 42, and airflow is transported to the corresponding tooth-shaped shells 42 through multiple air inlets 31. In other embodiments, one air inlet 31 can also be set to correspond to multiple tooth-shaped shells 42, and ventilation can be provided to multiple tooth-shaped shells 42 through one air inlet 31.

[0048] refer to Figure 3 and Figure 4 , there are also multiple inner teeth 5, and they correspond to the multiple tooth-shaped housings 42 one by one. The multiple inner teeth 5 are all connected to the air guide structure 3, and the multiple inner teeth 5 are respectively located in the multiple tooth-shaped housings 42 in a one-to-one correspondence. The inner teeth 5 are provided with a first surface and a second surface that are separated from each other, and when the inner teeth 5 are located inside the tooth-shaped housing 42, the first surface and the second surface are both in contact with the inner wall of the tooth-shaped housing 42, and a gap is left between the side wall of the inner teeth 5 located between the first surface and the second surface and the inner wall of the tooth-shaped housing 42, and the gap forms a ventilation channel 6, that is, the side wall of the inner teeth 5 located between the first surface and the second surface and the inner wall of the tooth-shaped housing 42 are surrounded to form the ventilation channel 6.

[0049] In addition, it should be noted that the toothed housing 42 is made of aluminum, which has a good thermal conductivity. In other embodiments, materials with good thermal conductivity such as aluminum alloy, iron, low carbon steel or ceramics can also be selected. The material is only exemplified in the embodiments of this application. In actual design, various materials commonly used in related fields can be used.

[0050] refer to Figure 4 The first surface and / or the second surface is provided with a groove, and the side wall of the groove and the inner wall of the toothed housing 42 are surrounded to form a drainage channel 51. Figure 5 In another embodiment, the drainage channel 51 is a through hole penetrating the inner tooth 5 , and both ends of the through hole are respectively connected to the first flow channel 61 and the second flow channel 62 .

[0051] In the embodiment of the present application, the drainage channel 51 is a groove, and the grooves are provided on both the first surface and the second surface as an example for description, and only the groove located on the first surface is used as an example to describe its specific shape and setting method, and the groove on the second surface is symmetrically arranged with the groove on the first surface. Of course, in some embodiments, the shapes of the grooves on the first surface and the second surface can be set to be different according to actual needs. In the case where the drainage channel 51 is a through hole, the shape of the through hole can refer to the specific way of setting the groove.

[0052] refer to Figure 3 , it is set that the flow direction of the airflow transported from the drainage channel 51 to the second flow channel 62 is the first direction, the flow direction of the airflow at the position where the second flow channel 62 is connected to the drainage channel 51 is the second direction, and the angle between the first direction and the second direction is an obtuse angle.

[0053] Exemplarily, the drainage channel 51 and the ventilation channel 6 are both V-shaped, and the two are bent in opposite directions, wherein the opening of the V-shaped structure formed by the ventilation channel 6 faces the direction of the wind guide structure 3, and the drainage channel 51 is V-shaped with the opening facing away from the direction of the wind guide structure 3. It should be noted that the ventilation channel 6 and the drainage channel 51 described in the embodiment of the present application are V-shaped, which means that the shapes of the ventilation channel 6 and the drainage channel 51 are approximately V-shaped, and other similar shapes can also be set in other embodiments, such as U-shaped, but the setting of the opening direction of the two ends of the drainage channel 51 needs to be adjusted according to the actual situation, rather than setting the openings at both ends to face the same direction.

[0054] In this case, by adjusting the inclination degree of the drainage channel 51 to different degrees, the first direction and the second direction are made to form obtuse angles of different sizes, so that when the two airflows converge, the heat generated by the impact and friction of the two airflows is greater than that at an acute angle or a right angle, and the heat generation efficiency is higher, that is, the heating efficiency of the air comb is higher and the effect is better.

[0055] In other embodiments, the angle between the first direction and the second direction may also be set to be an acute angle or a right angle.

[0056] refer to Figure 6 The flow direction of the airflow transmitted from the first flow channel 61 to the drainage channel 51 is the third direction, the flow direction of the airflow at the position where the first flow channel 61 is connected to the drainage channel 51 is the fourth direction, and the angle between the third direction and the fourth direction is an acute angle.

[0057] Exemplarily, the drainage channel 51 extends in a straight line, and the end of the drainage channel 51 connected to the first flow channel 61 is farther away from the connecting end than the end connected to the second flow channel 62, that is, closer to the side of the V-shaped structure opening formed by the ventilation flow channel 6.

[0058] In this case, the airflow is transmitted along the first flow channel 61. When it is transmitted to the position of the drainage channel 51, a part of it is diverted to the drainage channel 51, and is transmitted from the drainage channel 51 to the second flow channel 62, and converges with the airflow in the second flow channel 62, generating heat through impact and friction.

[0059] The angle between the third direction and the fourth direction is set to be an acute angle, which improves the smoothness of the airflow diverted from the first flow channel 61 to the drainage channel 51, and reduces the change in direction of the airflow in the process of diverting the airflow from the first flow channel 61 to the drainage channel 51. The airflow speed loss is small, and the energy lost in the transmission process is reduced. The main energy conversion process is carried out when the airflow converges in the second flow channel 62, which increases the heat generated in the second flow channel 62 and has a higher heat generation efficiency. The location where the airflow collides and frictionally generates heat is closer to the rear of the airflow transmission path, which is more conducive to improving the uniformity of the temperature at various positions of the air combing head.

[0060] In actual design, in addition to adjusting the size of the drainage channel 51 , the ratio of the airflow diverted from the first flow channel 61 to the drainage channel 51 can also be adjusted by adjusting the angle between the third direction and the fourth direction.

[0061] In some other embodiments, in addition to the above-mentioned limitation on the direction of the openings at both ends of the drainage channel 51, the specific direction of the drainage channel 51 can also be changed, for example, the drainage channel 51 can be set to a serpentine or other irregular shape; however, it should be noted that the more the direction of the drainage channel 51 is changed, the more energy the airflow loses when transmitting along the drainage channel 51, affecting the heat generation efficiency when the airflow converges in the second flow channel 62.

[0062] refer to Figure 2 and Figure 3 A cavity 33 is further provided in the air guide structure 3 , and the air outlets 32 are provided on both sides of the cavity 33 which are away from each other. The cavity 33 is configured to divert the airflow discharged from the second flow channel 62 to the air outlets 32 on both sides.

[0063] Specifically, the air outlet 32 ​​and the second flow channel 62 are both connected to the cavity 33. There are multiple air outlets 32, all of which are connected to the cavity 33, and the multiple air outlets 32 are respectively distributed on two sides of the cavity 33 that are away from each other; the arrangement direction of the multiple air outlets 32 on each side is the same as the arrangement direction of the multiple toothed housings 42. The path of the formed air flow channel is the air inlet channel 21-air inlet 31-first flow channel 61-second flow channel 62-cavity 33-air outlet 32. Of course, in the first flow channel 61-second flow channel 62 part, part of the air flow is transmitted through the drainage channel 51.

[0064] When the air comb is used, the discharged airflow is discharged in two divergent directions, which has a better heating effect.

[0065] In addition, reference Figure 7 The comb tooth assembly also includes a wind shield structure 7, which is arranged on the wind guide structure 3 and cooperates with multiple air outlets 32. The wind shield structure 7 selectively blocks the air outlets 32 on one side, while allowing the air outlets 32 on the other side to be in a normal air outlet state; in some embodiments, the wind shield structure 7 can also be set to allow the air outlets 32 on both sides to discharge air at the same time.

[0066] Specifically, the wind shield structure 7 includes two wind shields 71, and the two wind shields 71 ​​correspond to the air outlets 32 on both sides of the cavity 33 respectively. The two wind shields 71 ​​are slidably matched with the wind guide structure 3 to selectively block the air outlet path on one side, wherein the air outlet path refers to the channel path through which the airflow is discharged from the corresponding air outlet 32.

[0067] refer to Figure 8 and Fig. 9 In the embodiment of the present application, when a housing 1 is provided, a through hole 11 corresponding to the air outlet 32 ​​is provided on the housing 1, and the corresponding air outlet path is from the air outlet 32 ​​to the through hole 11 on the housing 1 to the outside of the air combing head. A windshield 71 is provided to be slidably connected with the housing 1 and abuts against the inner wall of the housing 1. A plurality of air outlets 711 are provided on the windshield 71, and the plurality of air outlets 711 correspond one-to-one to the plurality of through holes 11 on the housing 1. The windshield 71 is controlled to slide relative to the housing 1 so that the air outlet 711 is connected to the corresponding through hole 11, and the corresponding air outlet path is opened for air outlet; the windshield 71 can also be controlled to slide relative to the housing 1 so that the air outlet 711 is misaligned with the corresponding through hole 11, and the corresponding air outlet path is blocked.

[0068] In some other embodiments, a wind shield 71 may be provided to be in contact with the side wall of the air guide structure 3, and the exhaust port 711 may be provided corresponding to the air outlet 32. By sliding the wind shield 71, the exhaust port 711 and the corresponding air outlet 32 ​​may be connected or misaligned with each other, thereby realizing the change of the opening and blocking state of the air outlet path.

[0069] In some other embodiments, the outer shell 1 may not be provided. In this case, a wind shield 71 is provided to be in contact with the outer wall of the wind guide structure 3, the exhaust port 711 is provided in one-to-one correspondence with the air outlet 32, and the sliding wind shield 71 is used to adjust the air outlet path.

[0070] In the specific adjustment process, the air volume of the corresponding air outlet 32 ​​can also be adjusted by adjusting the area of ​​the air outlet 711 communicating with the air outlet 32 ​​or the through hole 11 on the housing 1 .

[0071] refer to Fig.10 The windshield structure 7 further includes a driving member 72 for driving the windshield plate 71 to slide. The driving member 72 includes a driving block 721 slidably connected to the housing 1 and a wrench 722 fixedly connected to the driving block 721. The wrench 722 penetrates the housing 1 and extends to the outside of the housing 1, so that the wrench 722 can be directly operated to drive the driving block 721 to slide. In addition, a driven block 73 is fixedly connected to one end of the windshield plate 71 facing the driving block 721, and the surface of the driven block 73 facing the driving block 721 is set as an inclined surface.

[0072] The driving block 721 slides between the two windshield plates 71, and respectively contacts with the driven blocks 73 on the two windshield plates 71, and drives the windshield plates 71 to slide by sliding with the inclined surfaces of the driven blocks 73. Fig. 9 A spring is also provided on the side of the wind shield 71 away from the driving block 721 .

[0073] In the natural state, the driving block 721 is separated from the driven block 73, and each air outlet path is in the open state and discharges air normally. When the air outlet direction needs to be adjusted or the air outlet volume needs to be changed, the driving block 721 is slid toward the wind shield 71 on one side, driving the corresponding wind shield 71 to slide in the direction away from the driving block 721, and squeezing the spring on the corresponding side, so that the size of the corresponding air outlet path is reduced or completely blocked. When the corresponding air outlet path needs to be opened later, the sliding driving block 721 is separated from the corresponding driven block 73, and the wind shield 71 returns to its original position under the action of the corresponding spring, so that the corresponding air outlet path is opened and air is discharged.

[0074] In some embodiments, by adjusting the size of the driving block 721 and its sliding stroke, two different air outlet solutions are selected. The first is that the air outlet paths on both sides always maintain a state of one connected and one blocked. The above-mentioned one connected and one blocked refers to complete connection or complete blockage. When the air outlet path on one side changes from connected to blocked, the air outlet path on the other side changes from blocked to connected at the same time. The second is that the air outlet paths on both sides can be connected at the same time, and the air outlet path on one side is blocked by sliding the driving block 721.

[0075] Regarding the specific manner of setting the driving member 72, in other embodiments, the driving member 72 can also be set as a gear rack structure driven by a motor, or a screw slider structure, or a linear telescopic mechanism such as an electric push rod and a cylinder is set to drive the windshield 71 to slide. In actual use, the specific type of the driving member 72 can be selected according to actual needs, and will not be described in detail in the embodiments of this application.

The movable tooth group 8 includes a tooth frame 81 and a plurality of divided teeth 82 fixedly connected to the tooth frame 81. The tooth frame 81 is slidably connected to the housing 1. The plurality of divided teeth 82 are respectively located in the gaps between two adjacent tooth-shaped housings 42. The tooth frame 81 slides relative to the comb tooth structure 4, driving the divided teeth 82 to contact or separate from the two adjacent tooth-shaped housings 42. The hair clamping function is achieved by the movable tooth group 8 cooperating with the comb tooth structure 4.

[0077] Exemplarily, the movable tooth group 8 also includes a lever button 83 and a spring for driving the gear rack 81 to slide. The lever button 83 and the spring are respectively located on two sides of the gear rack 81 that are away from each other. The lever button 83 is connected to the outer shell 1, with one end extending to the outside of the outer shell 1, and the other end being located on the inner side of the outer shell 1 and connected to the gear rack 81. One end of the spring abuts against the gear rack 81, and the other end abuts against the outer shell 1.

[0078] Specifically, the paddle button 83 is rotationally connected to the outer shell 1. In other embodiments, the paddle button 83 can also be arranged to be snap-connected or slidingly connected to the outer shell 1; the paddle button 83 abuts against the gear rack 81, and by pulling the end of the paddle button 83 located outside the outer shell 1, the end of the paddle button 83 located inside the outer shell 1 is driven to move, driving the gear rack 81 to slide away from the paddle button 83 and squeeze the spring. After the paddle button 83 is released, the gear rack 81 returns to its original position under the action of the spring.

[0079] In other embodiments, a motor-driven gear rack, a motor-driven screw slider structure, or a linear telescopic mechanism such as an electric push rod and a cylinder may be provided to drive the gear rack 81 to slide.

[0080] In addition, refer to Fig.12 A diverter plate 22 is provided inside the air duct 2, and the diverter plate 22 is configured to evenly distribute the airflow in the air inlet channel 21 in the arrangement direction of the air inlet 31; illustratively, there are multiple diverter plates 22, and the multiple diverter plates 22 are arranged at intervals along the extension direction of the air inlet 32; the diverter plate 22 is fixedly connected to the side of the air duct 2 where the air inlet 32 ​​is located, and in the air inlet direction, the edges of the multiple diverter plates 22 away from the side of the air inlet 32 ​​gradually move away from the air inlet 32; wherein the air inlet direction is the transmission direction of the airflow in the air inlet channel 21.

[0081] Thus, during use, the airflow is transmitted along the air inlet channel 21 and evenly distributed on the cross section of the air inlet channel 21. In the transmission direction of the airflow, each time it is transmitted to a diverter plate 22, a part of the airflow is blocked by the diverter plate 22 and diverted to the air inlet 32 ​​between the corresponding diverter plate 22 and the previous diverter plate 22; wherein the previous diverter plate 22 refers to the previous one in the air inlet direction. By setting the diverter plate 22, the uniformity of the airflow supplied to the multiple air inlets 32 can be improved, so that the heating effect of each part of the air combing head and the air outlet are more uniform, and the use effect is better.
