[0037] The utility model provides a massage comb.

[0038] Please refer to Figures 1 to 4 In one embodiment of the utility model, the massage comb includes a handle assembly, a comb tooth assembly 300 and a waterproof breathable component 400; the handle assembly includes a shell 100 and a power component 200 arranged in the shell 100, and the shell 100 is provided with a heat dissipation hole 120a; the comb tooth assembly 300 is installed in the shell 100 and is transmission-connected to the power component 200; the waterproof breathable component 400 is installed at the heat dissipation hole 120a.

[0039] The handle assembly refers to the part for the user to hold. The handle assembly includes a shell 100 and a power assembly 200 arranged in the shell 100, so that the shell 100 can have a good protective effect on the power assembly 200. In order to facilitate heat dissipation, the shell 100 can be made of a material with good heat dissipation performance. The shell 100 is provided with a heat dissipation hole 120a, which is used for the heat in the shell 100 to dissipate therefrom, thereby achieving the effect of heat dissipation in the shell 100. Specifically, the heat dissipation hole 120a can be provided with one, two or more. The shape of the heat dissipation hole 120a can be circular, rectangular or other shapes.

[0040] The waterproof breathable member 400 is a member having a waterproof function and capable of allowing gas to pass through. By installing the waterproof breathable member 400 at the heat dissipation hole 120a, on the one hand, the risk of water entering the housing 100 through the heat dissipation hole 120a opened on the housing 100 can be avoided, and on the other hand, the heat in the housing 100 can be dissipated while being waterproof, thereby achieving a better heat dissipation effect.

[0041] The power assembly 200 is a component that can provide a reciprocating swinging motion for the comb tooth assembly 300. The comb tooth assembly 300 is a main component that can directly contact the user's scalp and massage the user's scalp. The power assembly 200 includes a motor 210 and a cam mechanism, and the comb tooth assembly 300 is connected to the cam mechanism in a transmission manner, so that the comb tooth assembly 300 can also reciprocate to achieve the effect of massaging the user's scalp.

[0042] The technical solution of the utility model is to open a heat dissipation hole 120a on the housing 100 of the handle assembly, and a waterproof and breathable member 400 is installed at the heat dissipation hole 120a, so that the heat dissipation hole 120a has a waterproof and breathable effect, thereby ensuring the dustproof and waterproof effect, and dissipating the heat inside the housing 100. By arranging a power assembly 200 in the housing 100, and the comb tooth assembly 300 is installed on the housing 100 and connected to the power assembly 200 in a transmission manner, the power assembly 200 can provide power for the reciprocating motion of the comb tooth assembly 300, so that the comb tooth assembly 300 swings to close inward or open outward, thereby forming a grasping action to achieve the effect of massaging the user's scalp. In addition, combined with the heat dissipation hole 120a opened on the housing 100, the heat generated by the power assembly 200 in the housing 100 during operation can be dissipated through the heat dissipation hole 120a, reducing the risk of thermal expansion and deformation of the seal, thereby increasing the service life and waterproof sealing performance of the massage comb, and can reduce the temperature of the handle, and improve the user's experience.

[0043] In the embodiments of the present utility model, please refer to Figure 1 , Figure 5 as well as Figure 6A fan 500 is also provided in the housing 100, and the fan 500 is transmission-connected to the power assembly 200; the heat dissipation hole 120a includes an air inlet hole 121 and an air outlet hole 122, the air inlet hole 121 is connected to the air inlet side of the fan 500, and the air outlet hole 122 is connected to the air outlet side of the fan 500.

[0044] The heat dissipation hole 120a includes an air inlet 121 and an air outlet 122, so that the cold air from the outside can enter the housing 100 and exchange heat with the hot air in the housing 100, and the air after heat exchange flows out from the air outlet 122, and the massage comb achieves a good heat dissipation effect in this cycle; and such a configuration also avoids the risk of vacuum in the housing 100. By arranging a fan 500 in the housing 100, and the fan 500 is connected to the power assembly 200 by transmission, the power assembly 200 can drive the fan 500 to rotate, so that when the fan blades of the fan 500 stir the surrounding air, a pressure difference is formed between the air inlet side and the air outlet side of the fan 500, which is conducive to the airflow moving from the air inlet side of the fan 500 to the air outlet side, that is, it is conducive to the airflow to enter from the air inlet 121 stably and regularly, and to flow out from the air outlet 122 and increase the rate of airflow flowing out of the heat dissipation hole 120a, thereby improving the heat dissipation efficiency.

[0045] In combination with the above-mentioned scheme that the comb tooth assembly 300 is also connected to the power assembly 200 in a transmission manner, in this embodiment, a power assembly 200 can not only achieve the effect of driving the comb teeth to swing back and forth, but also achieve the effect of driving the fan 500 to rotate to accelerate the heat dissipation.

[0046] In the embodiments of the present utility model, please refer to Figure 1 , Figure 5 as well as Figure 6 The power assembly 200 includes a motor 210 and a gear set, wherein the motor 210 is disposed in the housing 100; the gear set is rotatably installed in the housing 100 and is transmission-connected to the motor 210; the comb assembly 300 and the fan 500 are both transmission-connected to the gear set.

[0047] By connecting the motor 210 to the gear set, the gear set can be rotated. In addition, by connecting the fan 500 to the gear set, the fan 500 can rotate with the gear set. By connecting the comb tooth assembly 300 to the gear set, the comb tooth assembly can be driven to swing back and forth when the gear set rotates, thereby massaging the scalp. In this embodiment, only one motor 210 is used to drive the comb teeth to swing and the fan 500 can be rotated to accelerate the heat dissipation of the hot air in the housing 100.

[0048] Specifically, the gear set may include at least two gears, one of which may be transmission connected to the fan 500, and the other gear may be transmission connected to the comb tooth assembly 300; alternatively, one of the gears may be transmission connected to the motor 210, and the other gear may be transmission connected to both the fan 500 and the comb tooth assembly 300; alternatively, the gear set may include at least three gears, wherein the three gears are transmission connected to the motor 210, the fan 500 and the comb tooth assembly 300, respectively.

[0049] In the embodiments of the present utility model, please refer to Figure 5 and Figure 6 The gear set includes a first gear 220 and a second gear 230 . The first gear 220 is transmission-connected to the motor 210 . The second gear 230 is transmission-connected to the first gear 220 . The fan 500 is coaxially fixedly connected to the second gear 230 .

[0050] By connecting the first gear 220 to the motor 210 and the second gear 230 to the first gear 220, the motor 210 drives the first gear 220 to rotate, and then the first gear 220 drives the second gear 230 to rotate. Further, by coaxially fixing the fan 500 to the second gear 230, the second gear 230 can drive the fan 500 to rotate synchronously. Specifically, the rotating shaft of the first gear 220 and the rotating shaft of the second gear 230 can be arranged in parallel or vertically, as long as they can be reasonably arranged according to the space in the housing 100 and ensure that the first gear 220 can be meshed with the second gear 230 for transmission.

[0051] In the embodiments of the present utility model, please refer to Figure 6 and Figure 7 A mounting groove 231 is formed on the second gear 230, and the fan 500 is fixedly installed in the mounting groove 231; an air inlet channel 232 and an air outlet channel are formed on the second gear 230, one end of the air inlet channel 232 is connected to the air inlet hole 121, and the other end is connected to the air inlet side of the fan 500; one end of the air outlet channel is connected to the air outlet hole 122, and the other end is connected to the air outlet side of the fan 500.

[0052] By forming a mounting groove 231 on the second gear 230, the fan 500 is fixedly mounted in the mounting groove 231. On the basis of the fan 500 being able to rotate with the second gear 230, the fan 500 can also reduce the space outside the second gear 230 that is additionally occupied by the fan 500, thereby improving the utilization rate of the space inside the housing 100 and helping to reduce the volume of the massage comb. In order to facilitate the airflow to flow from one side of the fan 500 to the other side and finally flow out of the housing 100 from the air outlet 122, an air inlet channel 232 and an air outlet channel are formed on the second gear 230. By connecting one end of the air inlet channel 232 to the air inlet 121 and the other end to the air inlet side of the fan 500, the airflow entering the housing 100 from the air inlet 121 can flow to the air inlet side of the fan 500 after passing through the air inlet channel 232 on the second gear 230, thereby reducing the risk of the air inlet side of the fan 500 being blocked by the second gear 230. By connecting one end of the air outlet channel to the air outlet hole 122 and the other end to the air outlet side of the fan 500, the wind flowing out from the air outlet side of the fan 500 first flows through the air outlet channel to the air outlet hole 122, and then flows out of the shell 100 from the air outlet hole 122. The setting of the air outlet channel, on the one hand, provides a flow guide for the air flow to flow to the air outlet hole 122, and on the other hand, avoids the risk of the air outlet side of the fan 500 being blocked.

[0053] Specifically, when the second gear 230 is provided with a mounting groove 231 and the fan 500 is installed in the mounting groove 231 of the second gear 230, the air inlet passage 232 may be provided on the side wall of the second gear 230, the wheel disc surface of the second gear 230, etc., and the air inlet passage 232 may be in a straight line, a curve, or a broken line shape, etc. The air outlet passage may also be provided on the side wall of the second gear 230, the wheel disc surface of the second gear 230, etc., and the air outlet passage may also be in a straight line, a curve, or a broken line shape, etc.

[0054] Please refer to Figure 6 and Figure 7 In the embodiment of the present invention, the fan 500 is interference fit with the mounting groove 231 .

[0055] By providing interference fit between the fan 500 and the mounting groove 231 , the number of connecting pieces between the fan 500 and the second gear 230 can be reduced, thereby reducing component costs and installation steps.

[0056] Of course, in other embodiments, the fan 500 and the mounting slot 231 may also be fixedly connected by means of a snap connection, a screw connection, or a magnetic connection.

[0057] Please refer to Figure 6 and Figure 7In the embodiment of the present invention, one of the side wall of the fan 500 and the side wall of the mounting slot 231 is provided with a protrusion 510 , and the other one is provided with a slot 234 , and the protrusion 510 is inserted into the slot 234 .

[0058] Specifically, the side wall of the fan 500 is provided with a protrusion 510, and the groove wall of the installation groove 231 is provided with a clamping groove 234. Alternatively, the side wall of the fan 500 is provided with a clamping groove 234, and the groove wall of the installation groove 231 is provided with a protrusion 510. By clamping the protrusion 510 into the clamping groove 234, the risk of slipping between the second gear 230 and the fan 500 can be reduced, thereby improving the stability of the second gear 230 rotating to drive the fan 500 to rotate synchronously.

[0059] Please refer to Figure 6 and Figure 7 In the embodiment of the present utility model, the mounting groove 231 and the locking groove 234 both penetrate the end surface of the second gear 230 away from the comb tooth assembly 300 .

[0060] By arranging both the mounting groove 231 and the clamping groove 234 through the end surface of the second gear 230 away from the comb tooth assembly 300, on the one hand, it is convenient for the fan 500 to be installed in the mounting groove 231 along the axial direction of the gear set from the side of the second gear 230 away from the comb tooth assembly 300, and at the same time, the effect of inserting the protrusion 510 into the clamping groove 234 is achieved; on the other hand, the installation of the fan 500 and the installation of the comb tooth assembly 300 can be carried out at the same time, and the two do not interfere with each other. In addition, by arranging both the mounting groove 231 and the clamping groove 234 through the end surface of the second gear 230 away from the comb tooth assembly 300, the action of inserting the main body of the fan 500 into the mounting groove 231 and the action of installing the protrusion 510 into the clamping groove 234 can be carried out at the same time, thereby saving installation time. In addition, it is understandable that if the slot 234 does not penetrate the end face of the second gear 230 away from the comb tooth assembly 300, the protrusion 510 on the fan 500 will be squeezed by the groove wall of the installation groove 231 at the beginning of inserting the fan 500 into the installation groove 231, making it difficult to install the fan 500 in place. In this embodiment, by setting the slot 234 to penetrate the end face of the second gear 230 away from the comb tooth assembly 300, the protrusion 510 will not be squeezed by the groove wall of the installation groove 231 when inserted into the slot 234 along the axial direction of the second gear 230, so that the fan 500 can be quickly and labor-savingly installed on the gear set.

[0061] like Figure 7 As shown, in an embodiment of the utility model, a swing track 235 is provided on the end face of one side of the gear set, and the comb tooth assembly 300 is inserted into the swing track 235. When the gear set rotates, the comb tooth assembly 300 is driven to swing back and forth in the radial direction of the gear set to retract inward or open outward.

[0062] By setting a swing track 235 on the end surface of one side of the gear set, and inserting the comb tooth assembly 300 into the swing track 235, the gear set can drive the comb tooth assembly 300 to swing back and forth in the radial direction of the gear set when rotating, thereby achieving the massage effect of the comb tooth assembly 300 on the scalp. Specifically, the comb tooth assembly 300 may include a plurality of comb tooth portions, which are distributed in a ring shape, and two adjacent comb tooth portions can move relative to each other; the swing track 235 is a non-circular track, so that the side wall of the swing track 235 forms a cam-like shape for the comb tooth assembly 300, and the swing track 235 is symmetrically arranged about its rotation center, so that the comb tooth assembly 300 can swing back and forth under the drive of the side wall of the swing track 235, so that each comb tooth portion can be retracted inward or opened outward, thereby achieving a pinching action to massage the scalp.

[0063] Specifically, when the gear set includes the first gear 220 and the second gear 230, the comb assembly 300 can be connected to the first gear 220 or the second gear 230. When the comb assembly 300 is connected to the first gear 220, the swing track 235 can be provided on the end surface of one side of the first gear 220; when the comb assembly 300 is connected to the second gear 230, the swing track 235 can be provided on the end surface of one side of the second gear 230.

[0064] like Figure 1 As shown, in an embodiment of the utility model, the shell 100 includes a main body 110 and a cover body 120, the power component 200 is installed in the main body 110, and the main body 110 has an installation opening; the cover body 120 is detachably connected to the main body 110, and the cover body 120 covers the installation opening; the heat dissipation holes 120a are all opened in the cover body 120, and the waterproof and breathable component 400 is installed on the side of the cover body 120 facing the inner cavity of the main body 110.

[0065] Since the handle assembly is usually in the shape of an elongated strip, in this embodiment, by detachably connecting the main body 110 and the cover body 120, it is convenient to install the power assembly 200 into the main body 110 through the installation opening of the main body 110 when the main body 110 and the cover body 120 are separated from each other, so as to achieve the effect that the power assembly 200 is easy to install in the housing 100. By covering the installation opening with the cover body 120, the housing 100 has good sealing performance, and the dustproof and waterproof effect of the massage comb is improved. In addition, by opening the heat dissipation hole 120a in the cover body 120, it is convenient to install the waterproof breathable member 400. By installing the waterproof breathable member 400 on the side of the cover body 120 facing the inner cavity of the main body 110, the area of ​​the waterproof breathable member 400 exposed to the outside is reduced, and the service life of the waterproof breathable member 400 is improved.

[0066] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
