[0065] As part of the inventive concept of the present application, before describing the embodiments of the present application, the causes of the long preheating time and poor heating effect of the air comb during use in the related art are analyzed, and the technical solution of the embodiments of the present application is obtained through reasonable analysis.

[0066] In the related art, hot air is generated during the use of the air comb, mainly by the PTC heating body to generate heat, the motor to work to generate airflow, to drive the airflow to blow through the PTC heating element to heat the airflow to generate hot air, and then the hot air is transferred to the air comb head to heat the heating body of the air comb head, generally the comb teeth, so that high-temperature heating straightening effect is achieved during combing, and the comb teeth are generally made of metal materials such as aluminum and aluminum alloy to maintain good heat transfer effect.

[0067] However, the current air comb head needs a long time to preheat and has poor heating effect when the airflow keeps flowing through the comb tooth position during use, resulting in poor experience effect.

[0068] Therefore, the present application provides an air comb to solve the technical problems of long preheating time and poor heating effect of the air comb head in the prior art.

[0069] The technical solutions of the embodiments of the present application are described in detail below in combination with the drawings. The technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0070] ReferenceFigure 1 In the embodiments of the present application, an air comb head is provided, which comprises a shell 1 serving as the overall framework basis of the air comb head structure, and the specific shape thereof can be adjusted according to actual needs. In addition, referring to Figure 2 and Figure 3 The air comb head further comprises a wind cylinder 2, a wind guide structure 3, a comb tooth structure 4 and inner teeth 5 arranged in the shell 1.

[0071] The wind cylinder 2 is arranged in the shell 1 and fixedly connected thereto, and the fixed connection mode can be clamping and holding fixation or adhesive fixation. The wind cylinder 2 is internally provided with an air inlet channel 21. In use, one end of the air inlet channel 21 is open and connected to a structure for generating hot air, so that the hot air is delivered into the air inlet channel 21. The cross-sectional shape of the wind cylinder 2 can be a polygon such as a rectangle, a pentagon or a circle, an ellipse or other irregular shape. In the embodiments of the present application, only the case where the cross section of the wind cylinder 2 is circular is taken as an example, and here it is meant that the inner and outer circles of the cross section of the wind cylinder 2 are circular.

[0072] The wind guide structure 3 is arranged on the wind cylinder 2, and in the embodiments of the present application, the two are integrally formed. Of course, in other embodiments, the two can also be arranged as a split structure and connected through clamping, adhesive, hot melt connection, bolt fixation and the like.

[0073] The wind guide structure 3 is provided with an air inlet 31 and an air outlet 32, and the air inlet 31 and the air outlet 32 are not connected to each other. Here, the air inlet 31 and the air outlet 32 are in a state of mutual independence in the wind guide structure 3. The air inlet 31 is connected to the air inlet channel 21, and correspondingly, the air outlet 32 is isolated from the air inlet channel 21.

[0074] The comb tooth structure 4 is connected to the wind guide structure 3, and the comb tooth structure 4 comprises a support 41 and a plurality of tooth-shaped housings 42 arranged on the support 41. The support 41 is fixedly connected to the wind guide structure 3, and the connection mode can also be clamping, adhesive, hot melt connection and the like. The cavities in the tooth-shaped housings 42 are connected to the air inlet 31 and the air outlet 32, so that the airflow in the air inlet channel 21 is delivered into the tooth-shaped housings 42 through the air inlet 31 and discharged from the air outlet 32. In addition to the above transmission path, the tooth-shaped housings 42 are sealingly connected to other positions of the wind guide structure 3. Correspondingly, the number of air inlets 31 is the same as that of tooth-shaped housings 42, and the airflow is delivered into the corresponding tooth-shaped housings 42 through the plurality of air inlets 31. In other embodiments, one air inlet 31 can correspond to a plurality of tooth-shaped housings 42, and the airflow is delivered into the plurality of tooth-shaped housings 42 through the one air inlet 31.

[0075] Referring to Figure 3 and Figure 4The inner tooth 5 is also provided with a plurality of inner teeth 5, which are one-to-one corresponding to the plurality of tooth-shaped housings 42, and the plurality of inner teeth 5 are connected to the air guide structure 3, and the plurality of inner teeth 5 are one-to-one corresponding to the plurality of tooth-shaped housings 42. The inner tooth 5 is provided with a first surface and a second surface facing away from each other, and the inner tooth 5 is located inside the tooth-shaped housing 42, and the first surface and the second surface are attached to the inner wall of the tooth-shaped housing 42. The gap between the side wall between the first surface and the second surface of the inner tooth 5 and the inner wall of the tooth-shaped housing 42 forms a ventilation flow channel 6, that is, the side wall between the first surface and the second surface of the inner tooth 5 and the inner wall of the tooth-shaped housing 42 form a ventilation flow channel 6.

[0076] The ventilation flow channel 6 is V-shaped, and is divided into a first flow channel 61 and a second flow channel 62 which are in communication with each other. The first flow channel 61 is away from the second flow channel 62 at one end, and the second flow channel 62 is away from the first flow channel 61 at one end. The end of the first flow channel 61 and the second flow channel 62 is a communication end. The first end is in communication with the air inlet 31, and the second end is in communication with the air outlet 32. The flow path of the air inlet channel 21-air inlet 31-first flow channel 61-second flow channel 62-air outlet 32 is formed.

[0077] The inner tooth 5 is provided with a flow guide channel 51, which is in communication with the first flow channel 61 and the second flow channel 62. One end of the flow guide channel 51 is located between the first end and the communication end, and the other end of the flow guide channel 51 is located between the second end and the communication end.

[0078] On the one hand, the first flow channel 61 and the second flow channel 62 are in communication through the communication 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 in communication through the flow guide channel 51, and two paths are formed from the air inlet 31 to the air outlet 32.

[0079] In this way, in the process of use, the airflow is transmitted according to the path of the air inlet channel 21-air inlet 31-first flow channel 61-second flow channel 62-air outlet 32, and a part of the airflow is split into the flow guide channel 51 during transmission in the first flow channel 61, and is transported to the second flow channel 62 from the flow guide channel 51. After converging with the airflow directly transported from the first flow channel 61 to the second flow channel 62, it is transmitted to the air outlet 32.

[0080] By setting the flow guide channel 51, a Tesla valve reverse flow channel is formed, that is, two air flow channels that are close to each other and collide in the positive direction. The flow guide channel 51 is approximately similar to the structure of the Tesla valve reverse flow channel. The air flow converges in the second flow channel 62, and when converging, the air flow collides and rubs to generate heat. The kinetic energy of the air flow is converted into heat energy. Compared with the prior art in which the air flow directly transmits along the ventilation flow channel 6 and flows through the tooth-shaped shell 42, the amount of heat generated in the tooth-shaped shell 42 is increased, the preheating time is shortened, the heating effect is improved, and the user experience is better.

[0081] On the other hand, in the existing comb structure, the temperature at the rear position in the air flow transmission path is lower, so that the heating efficiency and temperature of the air comb at the corresponding position are also lower. By setting the flow guide channel 51, the temperature of the second flow channel 62 near the air outlet 32, that is, the rear position in the air flow transmission path, can be improved to a certain extent, thereby improving the uniformity of the temperature at different positions of the air comb.

[0082] In addition, it should be noted that the tooth-shaped shell 42 is made of aluminum, which has good heat conduction effect. In other embodiments, materials with good heat conduction performance such as aluminum alloy, iron, low-carbon steel, or ceramic can also be selected. In the embodiments of the present application, only the material is exemplarily described, and various materials commonly used in the related field can be used in actual design.

[0083] Reference 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 tooth-shaped shell 42 form the flow guide channel 51. Figure 5 In another embodiment, the flow guide channel 51 is a through hole penetrating the inner tooth 5, and the two ends of the through hole are in communication with the first flow channel 61 and the second flow channel 62, respectively.

[0084] In the embodiments of the present application, the flow guide channel 51 is a groove, and the first surface and the second surface are both provided with a groove. Only the groove on the first surface is taken as an example to illustrate the specific shape and setting method. 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 different according to actual needs. In the case of a through hole as the flow guide channel 51, the shape of the through hole can refer to the specific setting method of the groove.

[0085] Reference Figure 3 The flow direction of the air flow transported by the flow guide channel 51 to the second flow channel 62 is the first direction, and the flow direction of the air flow at the position connected with the flow guide channel 51 in the second flow channel 62 is the second direction. The included angle between the first direction and the second direction is obtuse.

[0086] Exemplarily, the air flow channel 51 and the ventilation flow channel 6 are both V-shaped, and are bent in opposite directions, wherein the ventilation flow channel 6 is formed in a V-shaped structure with an opening facing the direction in which the air guide structure 3 is located, and the air flow channel 51 is formed in a V-shaped structure with an opening facing away from the direction in which the air guide structure 3 is located. It should be noted that the ventilation flow channel 6 and the air flow channel 51 described in the embodiments of the present application are V-shaped, which means that the shapes of the ventilation flow channel 6 and the air flow channel 51 are approximately V-shaped, and other embodiments can also be provided in other similar shapes, for example, U-shaped, but the opening direction of the two ends of the air flow channel 51 needs to be adjusted according to the actual situation, and the two ends are not arranged to face the same direction.

[0087] In this case, by adjusting the inclination of the air flow channel 51, the first direction and the second direction form obtuse angles of different sizes, so that when the two air flows converge, compared with the case of forming acute angles or right angles, the heat generated by the impact and friction of the two air flows is more, and the heat generation efficiency is higher, that is, the heating efficiency of the air comb is higher and the effect is better.

[0088] In other embodiments, the included angle between the first direction and the second direction can also be an acute angle or a right angle.

[0089] Reference Figure 6 The flow direction of the air flow transmitted from the first flow channel 61 to the air flow channel 51 is the third direction, and the flow direction of the air flow at the position where the first flow channel 61 is connected to the air flow channel 51 is the fourth direction, and the included angle between the third direction and the fourth direction is an acute angle.

[0090] Exemplarily, the air flow channel 51 extends along a straight line, and one end of the air flow channel 51 connected to the first flow channel 61 is farther away from the connection end than the other end connected to the second flow channel 62, that is, it is closer to the side of the opening of the V-shaped structure formed by the ventilation flow channel 6.

[0091] In this case, the air flow is transmitted along the first flow channel 61, and when it reaches the position of the air flow channel 51, part of it is diverted to the air flow channel 51, transmitted by the air flow channel 51 to the second flow channel 62, and converges with the air flow in the second flow channel 62 to generate heat by impact and friction.

[0092] By setting the included angle between the third direction and the fourth direction to be an acute angle, the smoothness of the air flow diverted from the first flow channel 61 to the air flow channel 51 is improved, and the amount of change in direction of the air flow during the diversion process is reduced, so that the speed loss of the air flow is small, the energy lost by the air flow during transmission is reduced, the main energy conversion process is carried out when the air flow converges in the second flow channel 62, the heat generated in the second flow channel 62 is improved, the heat generation efficiency is higher, and the position of the heat generated by the impact and friction of the air flow is closer to the rear of the air flow transmission path, which is more conducive to improving the uniformity of the temperature of each position of the air comb.

[0093] In actual design, in addition to adjusting the size of the flow channel 51, the proportion of the airflow shunted from the first flow channel 61 to the flow channel 51 can also be adjusted by adjusting the size of the angle between the third direction and the fourth direction.

[0094] In other embodiments, in addition to the above-mentioned orientation of the openings at both ends of the flow channel 51, the specific orientation of the flow channel 51 can also be changed, such as setting the flow channel 51 to be serpentine or other irregular shapes; however, it should be noted that the more the orientation of the flow channel 51 is changed, the more energy will be lost when the airflow is transmitted along the flow channel 51, affecting the heat production efficiency when the airflow converges in the second flow channel 62.

[0095] Reference Figure 2 and Figure 3 The air guide structure 3 is also provided with a cavity 33, and the mutually opposite two sides of the cavity 33 are provided with the above-mentioned air outlets 32, and the cavity 33 is configured to shunt the airflow discharged by the second flow channel 62 to the air outlets 32 on both sides.

[0096] Specifically, the air outlets 32 and the second flow channel 62 are both in communication with the cavity 33, the air outlets 32 are provided in plurality, are all in communication with the cavity 33, and the plurality of air outlets 32 are respectively distributed on the mutually opposite two sides of the cavity 33; the arrangement direction of the plurality of air outlets 32 on each side is the same as the arrangement direction of the plurality of tooth-shaped housings 42. The path of the airflow channel formed 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 airflow is also transmitted through the flow channel 51.

[0097] In the process of using the air comb, the discharged airflow is discharged in two directions away from each other, which has a good heating effect.

[0098] In addition, referring to Figure 7 The air comb further comprises a wind blocking structure 7, which is arranged on the air guide structure 3 and cooperates with the plurality of air outlets 32, the wind blocking structure 7 selectively blocks one side of the air outlet 32, and the other side of the air outlet 32 is in a normal air outlet state; in some embodiments, the wind blocking structure 7 can also be arranged to allow both sides of the air outlet 32 to blow air at the same time.

[0099] Specifically, the wind blocking structure 7 comprises two wind blocking plates 71, the two wind blocking plates 71 correspond to the air outlets 32 on both sides of the cavity 33, and the two wind blocking plates 71 are both in sliding cooperation with the air guide structure 3 and selectively block one side of the air outlet path, wherein the air outlet path refers to the channel path of the airflow discharged from the corresponding air outlet 32.

[0100] Reference Figure 8 andFigure 9 In the embodiment of the present application, the shell 1 is provided with a through hole 11 corresponding to the air outlet 32, and the corresponding air outlet path is from the air outlet 32 to the through hole 11 on the shell 1 to the outside of the air comb. The air baffle 71 is in sliding connection with the shell 1 and is attached to the inner side wall of the shell 1. The air baffle 71 is provided with a plurality of air outlets 711, which correspond one-to-one to the plurality of through holes 11 on the shell 1. The air baffle 71 is controlled to slide relative to the shell 1 so that the air outlet 711 communicates with the corresponding through hole 11, and the corresponding air outlet path is opened to blow air; the air baffle 71 can also be controlled to slide relative to the shell 1 so that the air outlet 711 is misaligned with the corresponding through hole 11, and the corresponding air outlet path is blocked.

[0101] In other embodiments, the air baffle 71 can also be attached to the side wall of the air guide structure 3, and the air outlet 711 is correspondingly arranged with the air outlet 32. By sliding the air baffle 71, the air outlet 711 is brought into communication or misalignment with the corresponding air outlet 32, so as to realize the change of the opening and blocking state of the air outlet path.

[0102] In other embodiments, the shell 1 can not be provided, in which case the air baffle 71 is attached to the outer side wall of the air guide structure 3, and the air outlet 711 is correspondingly arranged with the air outlet 32. The air baffle 71 is slid to adjust the air outlet path.

[0103] In the specific adjustment process, the area of the air outlet 711 in communication with the air outlet 32 or the through hole 11 on the shell 1 can also be adjusted to adjust the air volume of the corresponding air outlet 32.

[0104] Reference Figure 10 The air baffle structure 7 further comprises a driving member 72 for driving the air baffle 71 to slide. The driving member 72 comprises a driving block 721 in sliding connection with the shell 1 and a wrench 722 fixedly connected to the driving block 721. The wrench 722 extends outside the shell 1 so as to be directly operated to drive the driving block 721 to slide. In addition, the air baffle 71 is fixedly connected with a driven block 73 at one end facing the driving block 721. The surface of the driven block 73 facing the driving block 721 is provided as an inclined surface.

[0105] The driving block 721 slides between the two air baffles 71 and abuts against the driven blocks 73 on the two air baffles 71, respectively. By sliding cooperation with the inclined surface of the driven block 73, the air baffle 71 is driven to slide. In addition, in combination with reference Figure 9 A spring is also correspondingly provided on the side of the air baffle 71 away from the driving block 721.

[0106] In the natural state, the driving block 721 is separated from the driven block 73, and each air outlet path is in an open state for normal air outlet. When it is necessary to adjust the air outlet direction or change the air outlet volume, the driving block 721 is slid towards the direction of one of the air baffle plates 71, thereby driving the corresponding air baffle plate 71 to slide towards the direction away from the driving block 721, and pressing the spring on the corresponding side, so that the size of the corresponding air outlet path is reduced or completely blocked. When it is necessary to open the corresponding air outlet path, the driving block 721 is slid to be separated from the corresponding driven block 73, and the air baffle plate 71 is restored to the original position under the action of the corresponding spring, so that the corresponding air outlet path is opened for air outlet.

[0107] In some embodiments, by adjusting the size of the driving block 721 and the sliding stroke thereof, two different air outlet schemes can be selected. The first scheme is that the air outlet paths on both sides are always in a state of one being connected and the other being blocked. The above-mentioned one being connected or blocked means that the air outlet path is completely connected or blocked. In the process in which the air outlet path on one side changes from being connected to being blocked, the air outlet path on the other side changes from being blocked to being connected at the same time. The second scheme is that the air outlet paths on both sides can be connected at the same time, and one of the air outlet paths can be blocked by sliding the driving block 721.

[0108] For the specific manner of the driving member 72, in other embodiments, the driving member 72 can also be a gear and rack structure driven by a motor, or a screw and slider structure, or a linear extension mechanism such as an electric push rod or an air cylinder, to drive the air baffle plate 71 to slide. In actual use, the specific type of the driving member 72 can be selected according to actual needs, and the present application will not be described in more detail.

[0109] Reference Figure 11 The air comb head further comprises a movable tooth set 8 in sliding cooperation with the comb tooth structure 4. The movable tooth set 8 comprises a tooth rack 81 and a plurality of sub-teeth 82 fixedly connected to the tooth rack 81. The tooth rack 81 is in sliding connection with the shell 1, and the plurality of sub-teeth 82 are respectively located in the gaps between two adjacent tooth-shaped housings 42. The tooth rack 81 slides relative to the comb tooth structure 4, thereby driving the sub-teeth 82 to be attached to or separated from the respective two adjacent tooth-shaped housings 42. The clip hair function is realized by cooperation of the movable tooth set 8 and the comb tooth structure 4.

[0110] For example, the movable tooth set 8 further comprises a button 83 for driving the tooth rack 81 to slide and a spring. The button 83 and the spring are respectively located on the two sides of the tooth rack 81 away from each other. The button 83 is connected with the shell 1, and one end thereof extends to the outside of the shell 1, and the other end thereof is located inside the shell 1 and connected with the tooth rack 81. One end of the spring is in abutment with the tooth rack 81, and the other end thereof is in abutment with the shell 1.

[0111] Specifically, the knob 83 is rotationally connected with the shell 1, and in other embodiments, the knob 83 can also be provided with a clamping or sliding connection with the shell 1; the knob 83 abuts against the rack 81, and by pulling the end of the knob 83 outside the shell 1, the end of the knob 83 inside the shell 1 is driven to move, the rack 81 is driven to slide away from the knob 83, and the spring is extruded; after the knob 83 is released, the rack 81 is reset under the action of the spring.

[0112] In other embodiments, a motor-driven gear rack, a motor-driven screw slider structure, or a linear extension mechanism such as an electric push rod or a pneumatic cylinder can also be provided to drive the rack 81 to slide.

[0113] In addition, referring to Figure 12 , the inside of the air duct 2 is provided with a plurality of shunt plates 22, and the plurality of shunt plates 22 are arranged in the extension direction of the air inlet 32; the shunt 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 plurality of shunt plates 22 away from 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.

[0114] In this way, during use, the airflow is transmitted along the air inlet channel 21 and is uniformly distributed on the cross section of the air inlet channel 21, and in the transmission direction of the air inlet airflow, every time the airflow is transmitted to a shunt plate 22, a part of the airflow is blocked by the shunt plate 22 and is shunted to the air inlet 32 between the corresponding shunt plate 22 and the previous shunt plate 22; wherein the previous shunt plate 22 refers to the previous one in the air inlet direction. By providing the shunt plate 22, the uniformity of the airflow supplied to the plurality of air inlets 32 can be improved, so that the heating effect of each part of the air comb and the air outlet are more uniform, and the use effect is better.
