Technical Field
[0001] This application belongs to the field of health care comb technology, and in particular relates to a microcurrent comb. Background Technology
[0002] In modern life, people live at a fast pace and experience a lot of work and life pressure, which can easily damage the nerves. Regardless of whether they are blue-collar or white-collar workers, many people often experience headaches, dizziness, insufficient blood supply to the brain, and blocked meridians. In severe cases, this can even lead to hair loss.
[0003] People have long known from their life experience that combing hair can massage the scalp, which can not only increase blood flow to the hair roots and enhance the activity of melanocytes, but also stimulate nerve endings and promote blood circulation. Through the cerebral cortex, it can regulate the nerves in the head and relax the tense state of the head, which can significantly relieve mental stress.
[0004] However, existing combs, whether ordinary combs for daily use or health combs on the market, are basically composed of simple comb teeth fixed to a handle frame. When users use the comb to massage their scalp, they apply force to the comb and scrape the scalp. The comb teeth press against the scalp, transferring almost all the force to the scalp, causing scalp stinging. Utility Model Content
[0005] The purpose of this application is to provide a microcurrent comb that aims to solve the problem that the bristles of existing combs transmit almost all the force applied by the user to the scalp, causing scalp tingling.
[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a microcurrent comb, comprising a housing, a control board, an elastic surface shell, a first electrode foil, a second electrode foil, and multiple conductive comb teeth. The control board is disposed within the housing, the elastic surface shell is disposed within the housing, the first electrode foil and the second electrode foil are fixedly disposed on the elastic surface shell at intervals, the first electrode foil and the second electrode foil are respectively electrically connected to the control board and have opposite polarities, and the multiple conductive comb teeth are fixed on the elastic surface shell, at least some of the conductive comb teeth are electrically connected to the first electrode foil, and at least another portion of the conductive comb teeth are electrically connected to the second electrode foil. Each conductive comb tooth is used to contact the user's scalp to form a microcurrent circuit, and when scalp pressure is applied to the conductive comb teeth, the elastic surface shell, the first electrode foil, and the second electrode foil undergo elastic deformation.
[0007] In some embodiments, the elastic shell is provided with a plurality of insertion holes, and one end of a plurality of conductive comb teeth is inserted into the insertion holes and penetrates the elastic shell; at least a portion of the first electrode foil and at least a portion of the second electrode foil are covered and disposed inside the elastic shell; or, the first electrode foil and the second electrode foil are attached and fixed to the side of the elastic shell facing the housing, at least a portion of the conductive comb teeth penetrate the elastic shell and abut against the first electrode foil, and at least another portion of the conductive comb teeth penetrate the elastic shell and abut against the second electrode foil.
[0008] In some embodiments, the microcurrent comb also includes a phototherapy lamp, which is disposed in the housing and electrically connected to the control board. The elastic housing has a light-transmitting area, and the light emitted by the phototherapy lamp can pass through the light-transmitting area to irradiate the user's scalp.
[0009] In some embodiments, the elastic shell includes a central region, an inner ring region, and an outer ring region. The inner ring region surrounds the central region, and the outer ring region surrounds the inner ring region. Both the central region and the outer ring region are light-transmitting regions. A first electrode foil and a second electrode foil are disposed in the inner ring region, and the first electrode foil and the second electrode foil are symmetrically arranged with respect to the central axis of the inner ring region.
[0010] In some embodiments, the microcurrent comb further includes multiple light-guiding comb teeth, which are fixed in the light-transmitting area.
[0011] In some embodiments, the ends of both the conductive comb teeth and the light-guiding comb teeth away from the elastic shell are configured as spherical crowns.
[0012] In some embodiments, the resilient face shell is in the shape of a spherical crown protruding toward the side opposite to the shell.
[0013] In some embodiments, the housing includes a main housing and a handle portion. The main housing includes a first housing and a second housing, which are mutually capped. The handle portion is detachably connected to the side of the first housing away from the second housing. The circumferential edge of the elastic surface housing is sandwiched between the first housing and the second housing, and the elastic surface housing covers the second housing. The control panel is located inside the handle portion, and the phototherapy lamp is located in the second housing.
[0014] In some embodiments, the handle portion includes a connected handle housing and a connecting post. The first housing is provided with an insertion hole, the connecting post is inserted into the insertion hole, and the circumferential cylindrical surface of the connecting post is provided with a hook groove. The circumferential hole wall of the insertion hole is provided with a locking protrusion, and the hook groove is locked onto the locking protrusion to restrict the connecting post from coming out of the insertion hole.
[0015] In some embodiments, the outer contour of the handle housing is a spindle-shaped curve.
[0016] This application has at least the following beneficial effects: When a user combs their hair using the microcurrent comb provided in the embodiments of this application, the ends of the conductive comb teeth come into contact with the user's scalp. Since at least some of the conductive comb teeth are electrically connected to the first electrode foil and at least another part of the conductive comb teeth are electrically connected to the second electrode foil, and the first electrode foil and the second electrode foil have opposite polarities, the user's scalp, the corresponding conductive comb teeth, the first electrode foil, the second electrode foil, and the control board form a microcurrent circuit. The microcurrent stimulates the user's scalp, and combined with the comb teeth's massage of the user's scalp, it can not only increase blood flow to the hair roots and enhance the activity of melanocytes, but also stimulate nerve endings and promote blood circulation. It can regulate the nerves in the head through the cerebral cortex and relax the tense state of the head, which can significantly relieve mental stress. Furthermore, during the process of a user combing their hair using the microcurrent comb provided in the embodiments of this application, the user presses the comb so that the comb teeth press against the scalp. The corresponding comb teeth receive a reaction pressure from the scalp and this pressure is transmitted to the elastic shell and the first and second electrode foils thereon. At this time, the elastic shell, the first electrode foil, and the second electrode foil undergo elastic deformation. In other words, the elastic deformation of the elastic shell, the first electrode foil, and the second electrode foil can absorb some of the pressure applied by the user to the comb, thereby reducing the force transmitted from the comb teeth to the scalp. This helps to alleviate the stinging sensation caused by the comb teeth pressing against the scalp and improves the comfort of the comb teeth on the scalp during use. Attached Figure Description

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0023] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0024] like Figures 1 to 6 As shown, the microcurrent comb provided in the embodiments of this application includes a housing 10, a control board 20, an elastic surface shell 30, a first electrode foil 41, a second electrode foil 42, and a plurality of conductive comb teeth 51. The housing 10 provides mounting support for the remaining components. The control board 20 is disposed within the housing 10, and the elastic surface shell 30 is disposed within the housing 10. The first electrode foil 41 and the second electrode foil 42 are fixedly disposed at intervals on the elastic surface shell 30. The first electrode foil 41 and the second electrode foil 42 are electrically connected to the control board 20 respectively and have opposite polarities. The plurality of conductive comb teeth 51 are fixedly disposed on the elastic surface shell 30. At least some of the conductive comb teeth 51 are electrically connected to the first electrode foil 41, and at least another portion of the conductive comb teeth 51 are electrically connected to the second electrode foil 42. Each conductive comb tooth 51 is used to contact the user's scalp to form a microcurrent circuit, and when scalp pressure is applied to the conductive comb teeth 51, the elastic surface shell 30, the first electrode foil 41, and the second electrode foil 42 undergo elastic deformation.
[0025] When a user combs their hair using the microcurrent comb provided in the embodiments of this application, the ends of the conductive comb teeth 51 come into contact with the user's scalp. Since at least some of the conductive comb teeth 51 are electrically connected to the first electrode foil 41 and at least another part of the conductive comb teeth 51 are electrically connected to the second electrode foil 42, and the first electrode foil 41 and the second electrode foil 42 have opposite polarities, the user's scalp, the corresponding conductive comb teeth 51, the first electrode foil 41, the second electrode foil 42, and the control board 20 form a microcurrent circuit. The microcurrent stimulates the user's scalp, and combined with the comb teeth massaging the user's scalp, it can not only increase blood flow to the hair roots and enhance the activity of melanocytes, but also stimulate nerve endings and promote blood circulation. It can regulate the nerves in the head through the cerebral cortex and relax the tense state of the head, which can significantly relieve mental stress. Furthermore, during the process of a user combing their hair using the microcurrent comb provided in the embodiments of this application, the user presses the comb so that the comb teeth press against the scalp. The corresponding comb teeth receive a reaction pressure from the scalp and this pressure is transmitted to the elastic shell 30 and the first electrode foil 41 and the second electrode foil 42 thereon. At this time, the elastic shell 30, the first electrode foil 41, and the second electrode foil 42 undergo elastic deformation. That is to say, the elastic deformation of the elastic shell 30, the first electrode foil 41, and the second electrode foil 42 can absorb part of the pressure applied by the user to the comb, thereby reducing the force transmitted from the comb teeth to the scalp. This helps to reduce the stinging sensation caused by the comb teeth pressing against the scalp and improves the comfort of the comb teeth on the scalp during use.
[0026] In some embodiments, the microcurrent comb can be connected to a household electrical circuit via a connecting wire for power supply. Alternatively, in other embodiments, such as Figures 4 to 6 As shown, the microcurrent comb also includes a battery 21, which is located inside the housing 10 and is electrically connected to the control board 20, and is powered by the battery 21.
[0027] like Figure 6 and Figure 7As shown, the elastic shell 30 is provided with multiple insertion holes 31, and one end of multiple conductive comb teeth 51 is inserted into the insertion holes 31 and passes through the elastic shell 30. At least a portion of the first electrode foil 41 and at least a portion of the second electrode foil 42 are covered and disposed within the elastic shell 30. Specifically, a portion of the first electrode foil 41 and a portion of the second electrode foil 42 may be embedded within the elastic shell 30, or both the first electrode foil 41 and the second electrode foil 42 may be completely embedded within the elastic shell 30. When a portion of the first electrode foil 41 and a portion of the second electrode foil 42 are embedded in the elastic shell 30, the portion embedded in the elastic shell 30 consists of the two ends of the first electrode foil 41 and the second electrode foil 42, while the remaining portions of the first electrode foil 41 and the second electrode foil 42 are attached to the side of the elastic shell 30 facing the housing 10. In this case, one end of the conductive comb tooth 51 penetrating the elastic shell 30 abuts against the first electrode foil 41 or the second electrode foil 42 to achieve electrical connection. Alternatively, the portion embedded in the elastic shell 30 can be the remaining portion excluding the two ends. Or, both the first electrode foil 41 and the second electrode foil 42 are completely embedded in the elastic shell 30. In this case, one end of the conductive comb tooth 51 penetrating the elastic shell 30 also penetrates the first electrode foil 41 and the second electrode foil 42, thereby achieving electrical connection between a portion of the conductive comb tooth 51 and the first electrode foil 41, and electrical connection between the other portion of the conductive comb tooth 51 and the second electrode foil 42.
[0028] In some embodiments, the first electrode foil 41 and the second electrode foil 42 are attached and fixed to the side of the elastic shell 30 facing the housing 10. At least a portion of the conductive comb teeth 51 penetrate the elastic shell 30 and abut against the first electrode foil 41, and at least another portion of the conductive comb teeth 51 penetrate the elastic shell 30 and abut against the second electrode foil 42. In this embodiment, one end of the conductive comb teeth 51 penetrating the elastic shell 30 abuts against the first electrode foil 41 or the second electrode foil 42 to achieve electrical connection.
[0029] In the embodiments of this application, such as Figures 4 to 6As shown, the microcurrent comb also includes a phototherapy lamp 70, which is located in the housing 10 and electrically connected to the control board 20. The elastic housing 30 has a light-transmitting area, allowing the light emitted by the phototherapy lamp 70 to penetrate the light-transmitting area and irradiate the user's scalp, thereby achieving a phototherapy effect on the scalp. The light emitted by the phototherapy lamp 70 can be red light with a wavelength of 630nm-670nm, near-infrared light with a wavelength of 810nm-830nm, far-infrared light with a wavelength of 8µm-15µm, or blue light with a wavelength of 415nm. Among these, red light with a wavelength of 630nm-670nm is currently the most evidence-based "scalp therapy light"; blue light with a wavelength of 415nm targets inflammation; near-infrared light with a wavelength of 810nm-830nm targets deep nutrition; and far-infrared light with a wavelength of 8µm-15µm targets blood flow and relaxation. These four different wavelengths of light can be used alone or in combination to target different types of hair loss and scalp problems.
[0030] like Figure 7 As shown, the elastic shell 30 includes a central region 32, an inner ring region 33, and an outer ring region 34. The inner ring region 33 surrounds the central region 32, and the outer ring region 34 surrounds the inner ring region 33. The outline of the elastic shell 30 can be circular, elliptical, regular polygonal, rectangular, etc., and the shapes of the boundary lines between the central region 32 and the inner ring region 33, and between the inner ring region 33 and the outer ring region 34, are consistent with the outline of the elastic shell 30. Preferably, the outline of the elastic shell 30 is circular. In this embodiment, both the central region 32 and the outer ring region 34 are light-transmitting areas. The light emitted by the phototherapy lamp 70 passes through the central region 32 and the outer ring region 34 to irradiate the user's scalp. During the scalp combing process, the area of the head traversed by the microcurrent comb can achieve a phototherapy effect on the scalp. Furthermore, the first electrode foil 41 and the second electrode foil 42 are disposed in the inner ring region 33, and the first electrode foil 41 and the second electrode foil 42 are symmetrically arranged with respect to the central axis of the inner ring region 33. Correspondingly, a plurality of conductive comb teeth 51 are distributed on the inner ring region 33. In the embodiments of this application, the first electrode foil 41 and the second electrode foil 42 are semi-circular foils or arc-shaped foils with an arc-shaped elongated hole, and can be copper foils, steel foils, etc., preferably copper foils.
[0031] In the embodiments of this application, during the process of combing hair using the microcurrent comb, the light emitted by the phototherapy lamp 70 is easily blocked by hair after passing through the central region 32 and the outer ring region 34, thus reducing the light reaching the scalp. Therefore, as Figure 3 and Figure 7As shown, the microcurrent comb also includes multiple light-guiding comb teeth 52, which are fixed in the light-transmitting area. In this way, some light can be transmitted from the light transmission center area 32 and the outer ring area 34 and irradiate the scalp, while some light can be guided and propagated by the light-guiding comb teeth 52 to irradiate the scalp, thereby effectively improving the efficiency of the light emitted by the phototherapy lamp 70 to irradiate the scalp for phototherapy.
[0032] Among them, the conductive comb teeth 51 and the light-guiding comb teeth 52 of the microcurrent comb can be collectively referred to as comb teeth 50.
[0033] In the microcurrent comb of the embodiments of this application, such as Figure 8 As shown, the ends of both the conductive comb teeth 51 and the light-guiding comb teeth 52 furthest from the elastic shell 30 are configured with spherical crown-shaped comb tooth tips 53. The spherical crown-shaped comb tooth tips 53 can gently contact the scalp, making the scalp feel more comfortable and avoiding scalp injury caused by the sharp tips of the comb teeth 50.
[0034] In the microcurrent comb of this application embodiment, the elastic shell 30 is a spherical crown-shaped protrusion facing away from the shell 10. Furthermore, the lengths of each conductive comb tooth 51 extending from the elastic shell 30 and the lengths of each light-guiding comb tooth 52 extending from the elastic shell 30 are equal. Therefore, when a user combs their hair using this microcurrent comb, the user presses the comb so that each conductive comb tooth 51 and each light-guiding comb tooth 52 presses against the scalp. Since the spherical crown-shaped elastic shell 30 protrudes towards the scalp, the elastic shell 30 deforms most radially closer to its central axis. That is, among the multiple conductive comb teeth 51 and multiple light-guiding comb teeth 52, the comb teeth 50 that are radially closer to the central axis of the elastic shell 30 have better contact with the scalp. Thus, each conductive comb tooth 51 can make good contact with the scalp, thereby forming a larger microcurrent circuit, which is beneficial for improving the effect of microcurrent therapy on the scalp.
[0035] like Figures 4 to 6 As shown, in the microcurrent comb provided in the embodiments of this application, the housing 10 includes a main housing 11 and a handle portion 12. The main housing 11 includes a first housing 111 and a second housing 112, which are mutually capped. The handle portion 12 is detachably connected to the side of the first housing 111 facing away from the second housing 112. A control panel 20 is disposed within the handle portion 12 for convenient operation and control by the user. A phototherapy lamp 70 is disposed within the second housing 112, and a battery 21 is disposed within the main housing 11. Further, as... Figure 6As shown, the circumferential edge of the elastic shell 30 is sandwiched between the first shell 111 and the second shell 112, and the elastic shell 30 covers the second shell 112. In this way, the circumferential edge of the elastic shell 30 is clamped, fixed and positioned by means of the first shell 111 and the second shell 112, which not only improves the assembly efficiency, but also helps to make the assembly stability of the elastic shell 30 during deformation.
[0036] In some embodiments, such as Figures 4 to 6 As shown, the handle portion 12 includes a connected handle housing 121 and a connecting post 122. The handle housing 121 includes a first handle housing 1211 and a second handle housing 1212, and the connecting post 122 is located on the side of the second handle housing 1212 opposite to the first handle housing 1211. Furthermore, as... Figures 4 to 6 As shown, the first shell 111 has an insertion hole 113, through which the connecting post 122 is inserted to achieve detachable assembly between the handle part 12 and the main shell 11. Furthermore, the circumferential cylindrical surface of the connecting post 122 has a hook groove 123, and the circumferential wall of the insertion hole 113 has a locking protrusion 114. The hook groove 123 engages with the locking protrusion 114 to prevent the connecting post 122 from disengaging from the insertion hole 113. When it is necessary to detach the handle part 12 from the main shell 11, the user only needs to apply a pulling force to the handle part 12 and overcome the locking restriction between the hook groove 123 and the locking protrusion 114 to detach the handle part 12. This makes the microcurrent comb easier to store and more convenient to carry, as the handle part 12 is mounted on the main shell 11.
[0037] In the microcurrent comb of the embodiments of this application, the outer contour of the handle shell 121 is a spindle-shaped curve, and the outer contour of the handle shell 121 is more ergonomic and more comfortable for the user to hold.
[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
