[0043] The utility model provides a hair comb.

[0044] See also Figure 1 , Figure 2 , Figure 4 In one embodiment of the utility model, the hair comb comprises:

[0045] The housing 100 includes a handle portion 110, a combing portion 120, and a seat body 190. The handle portion 110 and the combing portion 120 are connected via the seat body 190 (see FIG. Figure 8 ), wherein the combing portion 120 is mounted on the handle portion 110, and the combing portion 120 and the handle portion 110 are in communication, wherein the housing 100 is provided with an air inlet 130, a first air outlet 140 and an air cavity 150, and the air inlet 130 and the first air outlet 140 are both in communication with the air cavity 150. In this embodiment, the air inlet 130 is provided on the handle portion 110, the first air outlet 140 is provided on the combing portion 120, and the air cavity 150 is the inner area of ​​the housing 100. In this embodiment, a fan and a heating element for heating air are also provided in the housing 100, and the external air is sucked into the housing 100, that is, into the air cavity 150, by the fan. When the air needs to be heated, the heating element is activated to heat the air, so that the air is hot air when it is blown out through the first air outlet 140. When the air does not need to be heated, the heating element is not activated, and the air is blown out from the first air outlet 140 at a normal temperature. In other embodiments, the air inlet 130 may also be provided at other positions of the housing 100, such as the combing portion 120. In this embodiment, a refrigeration element for cooling the air may also be provided in the housing 100, so that the air can be cooled by the refrigeration element and the temperature of the air blown out from the first air outlet 140 is reduced.

[0046] The comb teeth 200 are fixed to the first air outlet 140. There are many ways to fix the comb teeth 200 to the first air outlet 140, which are not limited here. The comb teeth 200 can be fixed by screws or by buckles. The installation area 400 is formed between the comb teeth 200 and the first air outlet side wall 140, and the wind blown out of the first air outlet 140 can be blown to the outside of the hair comb through the installation area 400. The comb teeth 200 are used for the user to comb the hair.

[0047] refer to Fig.10 , Fig.11The wind-exchanging tooth 300 includes a first mounting plate 310 and at least one first tooth 320. The first mounting plate 310 is rotatably mounted on the mounting area 400. In this embodiment, the rotatable mounting method between the first mounting plate 310 and the mounting area 400 is not limited. The following structure can be adopted. In this embodiment, the housing 100 is provided with a groove relative to the first mounting plate 310. The first mounting plate 310 is provided with a first rotating shaft 360 corresponding to the groove. The first rotating shaft 360 cooperates with the groove so that the first mounting plate 310 is rotatably mounted on the mounting area 400. The first mounting plate 310 has a first position 700 relative to the housing 100, that is, the air-exchanging tooth 300 has a first position 700 relative to the housing 100. In this embodiment, the first position 700 is the position where the air-exchanging tooth 300 is close to or against the first air outlet 140. That is, when the air-exchanging tooth 300 is located at the first position 700, the gap between the air-exchanging tooth 300 and the comb tooth 200 is large, and the gap between the air-exchanging tooth 300 and the housing 100 is small or there is no gap. The first tooth 320 is fixedly arranged on the side of the first mounting plate 310 away from the air cavity 150. A convex portion 380 is arranged on the side of the first mounting plate 310 facing the air cavity 150. The convex portion 380 is used to make the side of the first mounting plate 310 facing the air cavity 150 have an air-guiding surface 390, wherein the air-guiding surface can have a high and low position under the action of the convex portion 380, wherein the position close to the convex portion 380 is the high side of the air-guiding surface 390, and the position away from the convex portion 380 is the bottom side of the air-guiding surface. When the air-stirring teeth 300 are located at the first position 700, that is, when the air-stirring teeth 300 are located at the first position 700, the wind guide surface can make part of the wind blown out through the installation area 400 flow along the surface of the comb teeth 200. Since the air-stirring teeth 300 are located at the first position 700, at this time, the gap between the air-stirring teeth 300 and the comb teeth 200 is larger, and the gap between the air-stirring teeth 300 and the shell 100 is smaller or there is no gap. At this time, a part with more wind in the wind cavity 150 can be blown out from the shell 100 through the larger gap, that is, blown out from between the air-stirring teeth 300 and the comb teeth 200. At this time, under the action of the wind guide surface, the wind blown out through the wind cavity 150 can flow along the surface of the comb teeth 200. When the wind flows on the surface of the comb teeth 200, it can attract the hair close to the comb teeth 200, avoiding the hair sticking to the coin in the process of combing the hair, resulting in poor combing or ineffective combing, thereby improving the convenience of the comb when combing the hair, and thus solving the technical problems existing in the prior art.

[0048] However, the present design is not limited thereto. In other embodiments, the first mounting plate 310 is configured as a concave arc surface on one side facing the wind cavity 150. When the wind in the wind cavity 150 blows toward the concave arc surface, the wind acting on the concave arc surface can be diffused to both sides, so that the first mounting plate 310 can play a better wind guiding effect under the action of the concave arc surface. At the same time, in this embodiment, the low point close to the concave arc surface is the bottom surface of the wind guiding surface, and the high surface away from the low point of the concave arc surface is the high surface of the wind guiding surface.

[0049] In one embodiment, reference Fig. 9 , Fig.10 , Fig.11 The first mounting plate 310 is disposed outside the shell 100. When the first mounting plate 310 is disposed outside the shell 100, the wind in the wind cavity 150 needs to pass through the first air outlet 140 before acting on the wind guide surface, and then act on the wind guide surface. In this way, the wind in the wind cavity 150 can pass through the first air outlet 140 more smoothly, thereby increasing the air outlet efficiency.

[0050] For further reference, Fig. 9 , Fig.10 , Fig.11 In one embodiment, the first mounting plate 310 can be arranged outside the shell 100 through the following structure, and the air-exchanging tooth 300 also includes a connecting plate, and the first mounting plate 310 is rotatably installed in the mounting area 400 through the connecting plate. In this embodiment, the number of connecting plates is configured as two, and the two connecting plates are respectively arranged at the top and bottom of the first mounting plate 310, wherein the connecting plate is fixed to the first mounting plate 310, and at this time, the connecting plate is rotatably installed in the mounting area 400.

[0051] In one embodiment, the air-spreading tooth 300 is integrally formed, so as to further reduce the production cost of the air-spreading tooth 300 and improve the overall strength of the air-spreading tooth 300 .

[0052] In one embodiment, reference Fig. 9 , Fig.10 , Fig.11The first mounting plate 310 further has a second position 800 relative to the housing 100. In this embodiment, when the first mounting plate 310 is located at the second position 800, that is, the air-exchanging teeth 300 are located at the second position 800. At the same time, the second position 800 is the position where the air-exchanging teeth 300 are close to or against the comb teeth 200. That is, when the air-exchanging teeth 300 are located at the second position 800, the gap between the air-exchanging teeth 300 and the comb teeth 200 is small or there is no gap. When the air-stirring teeth 300 are located at the second position 800, the wind blown out through the installation area 400 will have less wind flowing along the surface of the comb teeth 200 or no wind flowing along the surface of the comb teeth 200; the installation area 400 and the air-stirring teeth 300 are both configured as two, and the two air-stirring teeth 300 are installed in the two installation areas 400 in a one-to-one correspondence, and the two installation areas 400 are symmetrically arranged about the comb teeth 200. At the same time, when one of the air-stirring teeth 300 is located at the first position 700, the other air-stirring teeth 300 is located at the second position 800, so that only one wind direction of the wind blown out through the two installation areas 400 can flow along the surface of the comb teeth 200, so that the hair is adsorbed on the comb teeth 200. In addition, in the present embodiment, under the action of the two air-stirring teeth 300 and the two installation areas 400, the user can switch between the left and right hands during use, further improving the performance of the present application. In this embodiment, when the user combs the hair with the hairbrush, one of the air-push teeth 300 contacts the hair first, and the other contacts the hair later. During the combing process, the air-push teeth 300 that contact the hair first will be in the second position 800 due to the resistance of the hair. The air-push teeth 300 that contact the hair later will be in the first position 700 due to the resistance of the hair. After the hairbrush combs the hair, the air-push teeth 300 located in the first position 700 can make the wind blown out through the installation area 400 flow partially along the surface of the comb teeth 200. At this time, when the wind flows along the surface of the comb teeth 200, it can have an adsorption effect on the hair, making the hair fluffy, thereby increasing the number of effective combing times of the hairbrush, thereby solving the technical problems existing in the prior art.

[0053] In other embodiments, when there is only one air-stirring tooth 300, when the hair comb is in use, the comb tooth 200 contacts the hair first and the air-stirring tooth 300 contacts the hair last. In this way, the air-stirring tooth 300 can rotate to the first position 700 under the action of the resistance of the hair, so that the wind blown out through the installation area 400 partially flows along the surface of the comb tooth 200.

[0054] In one embodiment, reference Fig. 9 , Fig.10 , Fig.11When the protrusion 380 is arranged near the middle of the side of the first mounting plate 310 facing the wind cavity 150, the protrusion 380 enables the side of the first mounting plate 310 facing the wind cavity 150 to have two wind guide surfaces. In other words, when the wind in the wind cavity 150 directly acts on the side of the first mounting plate 310 facing the wind cavity 150, the wind can be directed to both sides under the action of the protrusion 380. At the same time, when the air-spreading tooth 300 is located at the first position 700, under the action of the protrusion 380, more wind can be guided to flow out between the comb teeth 200 and the air-spreading tooth 300. When the air-spreading tooth 300 is located at the second position 800, under the action of the protrusion 380, more wind can be guided to flow out between the air-spreading tooth 300 and the first outlet in the housing 100.

[0055] In one embodiment, reference Figure 5 In order to enable one of the air-steering teeth 300 to be located at the first position 700 and the other air-steering tooth 300 to be stably located at the second position 800, the hair comb further includes a linkage assembly 500, referring to Figure 6 , Figure 7 , the linkage assembly 500 is used to connect the two air-exchanging teeth 300, so that one of the two air-exchanging teeth 300 is located at the first position 700, and the other is located at the second position 800. In the present embodiment, the linkage assembly 500 may adopt the following structure, and the linkage assembly 500 includes a linkage seat. The two connecting plates in the air-exchanging teeth 300 are respectively a first connecting plate 330 and a second connecting plate 340, wherein the first connecting plate 330 is connected to the first linkage seat 510, wherein the first connecting plate 330 and the first linkage seat 510 are connected via a second rotating shaft 370. In the present embodiment, the first rotating shaft 360 is fixed to the first connecting plate 330, wherein the first rotating shaft 360 and the second rotating shaft 370 are respectively located on two opposite end surfaces of the connecting plate. When the air-steering teeth 300 rotate, the second rotating shaft 370 can swing around the first rotating shaft 360, and then through the linkage seat, when one air-steering tooth 300 rotates, the other air-steering tooth 300 can also rotate in the same direction as it, so that when one air-steering tooth 300 is located at the first position 700, the other air-steering tooth 300 is located at the second position 800.

[0056] Further, in one embodiment, referring to Figure 6 , Figure 7In order to enable the linkage structure to position the air-stirring teeth 300 at the first position 700 during use, the hair comb further includes a positioning member 600, which is used to position one of the air-stirring teeth 300 at the first position 700. When one of the air-stirring teeth 300 is positioned at the first position 700, the other air-stirring teeth 300 is positioned at the second position 800. In this way, when the user is combing the hair, even if the resistance between the air-stirring teeth 300 and the hair is small, that is, when the resistance of the hair cannot make the air-stirring teeth 300 be located at the first position 700, the air-stirring teeth 300 will not rotate from the first position 700 to the second position 800 under the action of the positioning member 600. In this way, when the user is using the hair comb, the air-stirring teeth 300 will not automatically rotate from the first position 700 to the second position 800, thereby further ensuring the effective combing times of the hair comb during the hair combing process.

[0057] Further, in one embodiment, referring to Figure 6 , Figure 7 , the first connecting plate 330 is provided with a positioning groove 350, and the positioning groove 350 cooperates with the positioning member 600. When the positioning member 600 is inserted into the positioning groove 350, one of the air-exchanging teeth 300 is positioned at the first position 700. In this embodiment, the first connecting plates 330 on the two air-exchanging teeth 300 are both provided with positioning grooves 350, and two positioning members 600 corresponding to the positioning grooves 350 are also provided; when the air-exchanging teeth 300 are located at the second position 800, the positioning member 600 corresponding to the second position 800 is not inserted into the positioning groove 350 on the connecting plate located at the second position 800, and when the air-exchanging teeth 300 are located at the first position 700, the positioning member 600 corresponding to the first position 800 is inserted into the positioning groove 350 on the connecting plate located at the first position 700.

[0058] Further, in one embodiment, referring to Figure 7 The positioning member 600 is configured as an elastic pin or a positioning glass bead. In this embodiment, the elastic pin includes a pin body 610 and a spring 620, wherein the spring 620 is sleeved outside the pin body 610, and the elastic pin and the housing 100 are slidably matched. When the elastic pin corresponds to the positioning groove 350, the pin body 610 can be inserted into the positioning groove 350 under the action of the spring 620, so as to position one of the air-moving teeth 300 at the first position 700.

[0059] In one embodiment, reference Figure 6The comb teeth 200 include a second mounting plate 210 and a plurality of second teeth 220, the plurality of second teeth 220 are fixedly mounted on the second mounting plate 210, the second mounting plate 210 is fixedly mounted on the first air outlet 140, in this embodiment, the side of the second mounting plate 210 facing the air cavity 150 is configured as an inner concave arc surface, under this structure, the wind can flow better in the air cavity 150. In this embodiment, the comb teeth 200 can be processed by an integrated molding method, so that the production and processing of the comb teeth 200 can be facilitated.

[0060] In one embodiment, reference Figure 3 , Figure 5 The hair comb also includes a second air outlet 160, and a plurality of second air outlets 160 are opened on the shell 100 and communicated with the wind cavity 150, wherein the second air outlet 160 is opened on the combing part 120. In the present embodiment, the shell 100 is configured as a cylindrical structure, so that when using the hair comb, the user can wrap the hair around the outside of the shell 100 through the comb teeth 200, and the hair wrapped around the shell 100 can be quickly dried under the action of the second air outlet 160, thereby achieving the purpose of quick-drying the hair, further improving the use effect of the present application.

[0061] In one embodiment, reference Figure 3 , Figure 5 The hair comb further includes a plurality of third air outlets 170, which are provided in the housing 100 and communicated with the air cavity 150. Bristles 180 are installed in the plurality of third air outlets 170, and a gap is provided between the bristles 180 and the third air outlets 170 for air to pass through.
