Description

Technical Field

[0001] This utility model relates to the field of beauty instruments, and in particular to a scraping beauty instrument with alternating electrical stimulation function. Background Technology

[0002] Gua sha, guided by the theory of meridians and acupoints in Traditional Chinese Medicine, involves using specialized tools and techniques, applying a medium, and repeatedly scraping and rubbing the skin to induce "sha" changes, such as red millet-like or dark red bleeding points, thereby promoting blood circulation and removing sha. Traditional gua sha methods primarily rely on gua sha boards made of Bian stone, jade, or ox horn, combined with liquid or cream-based gua sha oil. However, traditional gua sha requires manual control of three core elements: angle, pressure, and speed. Without professional training, users are prone to errors such as incorrect scraping angle and improper pressure control, which not only affects the effectiveness but may also cause skin damage (such as bruising and scratches). Furthermore, traditional gua sha only achieves mechanical scraping, offering limited functionality and failing to meet the diverse needs of users.

[0003] Therefore, with the advancement of technology and the increasing demand for beauty and health care, modern beauty techniques such as hot compresses, phototherapy, and electrical stimulation are being integrated into gua sha tools. In addition, skin care products are being used instead of traditional gua sha mediums. This can promote the absorption of skin care products by the skin while performing gua sha, thus achieving the effect of beauty and skin care. For example, Chinese invention application CN119074498A discloses a gua sha device, which includes a shell. The shell is equipped with a gua sha head, a heat therapy mechanism, a red light mechanism, a microcurrent mechanism, and a massage mechanism. The heat therapy mechanism is used to provide a heat therapy effect during gua sha, and the red light mechanism is used to provide red light irradiation during gua sha. This gua sha device integrates microcurrent massage, red light, heat therapy, and vibration massage. It can not only use EMS microcurrent to lift and tighten the skin, but also use red light combined with heat therapy to open pores to promote the absorption of skin care products and penetrate the skin surface to help relax deep muscles. In addition, it can also massage the skin with high-frequency micro-vibration to further promote the absorption of skin care products. Furthermore, the contraction and relaxation of the skin during massage can exercise the skin, thereby enhancing the gua sha massage effect brought by the gua sha device. However, the red light combined with heat from the aforementioned gua sha device can only open the pores and gaps between the stratum corneum on the skin's surface. Skincare products have difficulty penetrating the stratum corneum to reach the dermis, especially for ingredients with larger molecular weights such as hyaluronic acid and peptides, which cannot penetrate the stratum corneum at all. As a result, most of the skincare products remain on the skin's surface and are easily removed during subsequent wiping or massage. The actual utilization rate of skincare products is less than 30%, resulting in waste.

[0004] Therefore, it is necessary to provide a technical solution to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a gua sha beauty device with alternating electrical stimulation function, which can solve the technical problem that existing gua sha devices cannot effectively utilize skin care products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gua sha beauty device with alternating electrical stimulation function includes a housing assembly and a control circuit board. A gua sha massage head is installed at one end of the housing assembly, and the control circuit board is disposed in the housing assembly. The gua sha massage head includes a massage head housing and multiple electrode plates disposed on the massage head housing. The multiple electrode plates are respectively connected to the control circuit board and are insulated from each other. The control circuit board is provided with an EMS microcurrent circuit and an EP electroporation circuit. The EMS microcurrent circuit and the EP electroporation circuit alternately output operating current to the electrode plates.

[0008] Furthermore, it also includes a conductive support mechanism, which is disposed between the control circuit board and the plurality of electrode plates. The conductive support mechanism includes a number of support columns, each of which has a through hole and a conductive spring disposed in each through hole. One end of each conductive spring contacts the control circuit board and the other end contacts the electrode plate. Each electrode plate is in contact with at least one conductive spring.

[0009] Furthermore, the conductive support mechanism also includes at least one base plate, which is connected to the control circuit board, and a plurality of the support columns are disposed on the base plate. The base plate is provided with through holes communicating with each of the through holes.

[0010] Furthermore, each of the electrode plates has at least one conductive plug-in structure on its inner surface. Each conductive plug-in structure includes a support portion and a plug-in portion arranged sequentially along the direction away from the electrode plate. The plug-in portion is inserted into and in contact with the conductive spring. The end of the support portion away from the electrode plate is supported on the end of the support post near the electrode plate.

[0011] Furthermore, the control circuit board is also provided with a skin contact detection circuit, which is used to detect whether the electrode pad is in contact with the skin.

[0012] Furthermore, at least a portion of the inner surface of the electrode sheet is provided with a heating film, and a temperature sensor is disposed in the heating film. Both the heating film and the temperature sensor are connected to the control circuit board.

[0013] Furthermore, it also includes a control button assembly, which is disposed on the housing assembly. The control button assembly includes a power button, an electrical stimulation level adjustment button, and a temperature level adjustment button. The power button, the electrical stimulation level adjustment button, and the temperature level adjustment button are all connected to the control circuit board. The electrical stimulation level adjustment button is used to adjust the intensity of the output current of the EMS microcurrent circuit and the EP electroporation circuit, and the temperature level adjustment button is used to adjust the output temperature of the heating film.

[0014] Furthermore, it also includes several phototherapy lamp beads, which are disposed on the control circuit board, and the light emitted by the several phototherapy lamp beads is emitted outward through the massage head housing.

[0015] Furthermore, it also includes a rechargeable battery, which is disposed in the housing assembly. The housing assembly is provided with a charging interface, and both the rechargeable battery and the charging interface are connected to the control circuit board.

[0016] Furthermore, it also includes a protective cover, which can be placed on the outside of the scraping massage head and is detachably connected to the housing assembly; the housing assembly includes an inner housing and an outer housing, the inner housing is provided with a mounting cavity, the control circuit board is disposed in the mounting cavity, and the outer housing is installed on the outside of the inner housing.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) By setting an EP electroporation circuit on the control circuit board of the gua sha beauty instrument, the EP electroporation circuit outputs an action current to the electrode plate, which makes reversible micropores form on the stratum corneum of the skin, so that the ingredients in the skin care products, especially the ingredients with large molecular weight such as hyaluronic acid and peptides, can reach the dermis more efficiently through the micropores, greatly improving the utilization rate of the skin care products.

[0019] (2) By setting an EMS microcurrent circuit on the control circuit board, the EMS microcurrent circuit outputs an action current to the electrode plate, which stimulates the contraction and relaxation of facial muscles by simulating the electrical signals emitted by the brain, thereby achieving the effect of lifting the skin and improving facial sagging.

[0020] (3) By setting the EMS microcurrent circuit and the EP electroporation circuit to alternately output the working current to the electrode plate, the user feels an intermittent slight tingling sensation, which allows the user to perceive that the gua sha beauty device is applying electrical stimulation to the skin, which helps to improve the user experience; and because the EP electroporation function allows the ingredients of the skin care product to enter the dermis, and the EP electroporation function and the EMS microcurrent function alternate, the EMS microcurrent function causes the facial muscles to contract and relax, which promotes the skin care product ingredients that have entered the dermis to diffuse to the surrounding area, avoiding the accumulation of skin care product ingredients in the local area, and further improving the utilization efficiency of skin care product ingredients.

Detailed Implementation

[0031] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0032] like Figures 1 to 5 As shown in the figure, this embodiment provides a gua sha beauty device with alternating electrical stimulation function, including a housing assembly 1 and a control circuit board 2. A gua sha massage head 3 is installed at one end of the housing assembly 1, and the control circuit board 2 is disposed in the housing assembly 1. The gua sha massage head 3 includes a massage head housing 31 and a plurality of electrode plates 32 disposed on the massage head housing 31. The plurality of electrode plates 32 are respectively connected to the control circuit board 2 and are insulated from each other. The control circuit board 2 is provided with an EMS microcurrent circuit and an EP electroporation circuit. The EMS microcurrent circuit and the EP electroporation circuit alternately output operating current to the electrode plates 32. Specifically, the gua sha beauty device in this embodiment is used on the human face. Therefore, along the length of the gua sha massage head 3, the top of the gua sha massage head 3 has a slightly concave arc shape to match the curvature of the human face, thereby allowing the gua sha massage head 3 to better fit the human face; and the cross-section of the gua sha massage head 3 has a rounded arc shape, improving the comfort when the gua sha massage head 3 contacts the human face. Furthermore, as... Figure 5As shown, the electrode pads 32 include three pairs of positive and negative electrodes. The first pair of positive and negative electrodes 323 is located in the middle of the massage head housing 31, while the second pair of positive and negative electrodes 324 and the third pair of positive and negative electrodes 325 are located at both ends of the massage head housing 31. Each electrode pad 32 is curved to fit the shape of the gua sha massage head 3. This arrangement ensures that regardless of the angle at which the massage head housing 31 contacts the face, there is always an electrode pad 32 in contact with the facial skin, eliminating the need for the user to position the massage head housing 31 at a specific angle, thus improving ease of use. Furthermore, the massage head housing 31 is made of insulating material, and the multiple electrode pads 32 are spaced apart on the massage head housing 31, thus ensuring that the electrode pads 32 are insulated from each other.

[0033] In this embodiment, an EP electroporation circuit is provided on the control circuit board 2 of the gua sha beauty device. The EP electroporation circuit outputs an active current to the electrode plate 32, that is, it outputs a pulsed electric field on the skin, which creates reversible micropores in the stratum corneum of the skin. This allows the ingredients in skin care products, especially those with larger molecular weights such as hyaluronic acid and peptides, to reach the dermis more efficiently through these micropores, greatly improving the utilization rate of skin care products. The control circuit board 2 in this embodiment is also equipped with an EMS microcurrent circuit. The EMS microcurrent circuit outputs an active current to the electrode plate 32, simulating the electrical signals emitted by the brain to stimulate facial muscle contraction and relaxation, achieving the effect of lifting the skin and improving facial sagging. Furthermore, since the skin feels nothing during EP electroporation, but experiences a slight tingling sensation during EMS microcurrent, users cannot perceive whether the gua sha device is working if only EP electroporation is used, resulting in a poor user experience. Therefore, this embodiment uses an alternating current output to the electrode 32 via the EMS microcurrent circuit and EP electroporation circuit, allowing the user to experience intermittent, slight tingling sensations. This enables the user to perceive that the gua sha device is applying electrical stimulation to the skin, improving the user experience. Additionally, since EP electroporation allows skincare product ingredients to penetrate the dermis, and the alternating use of EP electroporation and EMS microcurrent in this embodiment causes facial muscles to contract and relax, the skincare product ingredients already in the dermis diffuse outwards, preventing localized accumulation and further enhancing the utilization efficiency of the skincare product ingredients.

[0034] Furthermore, it also includes a conductive support mechanism 4, which is disposed between the control circuit board 2 and the plurality of electrode plates 32. The conductive support mechanism 4 includes several support columns 41, each of which has a through hole 411. Each through hole 411 contains a conductive spring 42, one end of which contacts the control circuit board 2 and the other end of which contacts the electrode plate 32. Each electrode plate 32 is in contact with at least one conductive spring 42. In this embodiment, the conductive springs 42 connect the electrode plates 32 to the control circuit board 2, and the support columns 41 are also provided. On the one hand, the support columns 41 can limit the conductive springs 42 to prevent them from bending and deforming. On the other hand, the support columns 41 provide support for the scraping massage head 3, reducing the possibility of deformation of the scraping massage head 3.

[0035] Furthermore, the conductive support mechanism 4 also includes at least one base plate 43, which is connected to the control circuit board 2. A plurality of support columns 41 are disposed on the base plate 43, and the base plate 43 has through holes communicating with each of the through holes 411. Specifically, two base plates 43 are provided, and the two base plates are respectively disposed on the control circuit board 2 corresponding to both ends of the scraping massage head 3. Each base plate 43 has a plurality of support columns 41. In this embodiment, the base plate 43 is provided to facilitate the installation of the support columns 41.

[0036] Furthermore, each electrode plate 32 has at least one conductive insertion structure on its inner surface. Each conductive insertion structure includes a support portion 321 and an insertion portion 322 arranged sequentially along a direction away from the electrode plate 32. The insertion portion 322 is inserted into and contacts the conductive spring 42. The end of the support portion 321 away from the electrode plate 32 is supported on the end of the support post 41 near the electrode plate 32. In this embodiment, the insertion portion 322 ensures effective contact between the electrode plate 32 and the conductive spring 42, and the support portion 321 further strengthens the support of the support post 41 for the scraping massage head 3.

[0037] Furthermore, the control circuit board 2 is also equipped with a skin contact detection circuit, which is used to detect whether the electrode pad 32 is in contact with the skin. Specifically, the contact state can be determined by detecting the contact impedance between the electrode pad 32 and the skin, which is existing technology and will not be described in detail here. In this embodiment, by setting up a skin contact detection circuit, the EMS microcurrent circuit and the EP electroporation circuit are activated to alternately output working current to the electrode pad 32 only when the skin contact detection circuit detects that the electrode pad 32 is in contact with the skin, thus avoiding the stinging sensation caused by activating the EMS microcurrent circuit when the electrode pad 32 is in near-contact with the skin.

[0038] Furthermore, at least a portion of the inner surface of the electrode sheet 32 ​​is provided with a heating film 5, and a temperature sensor is disposed in the heating film 5. Both the heating film and the temperature sensor are connected to the control circuit board 2. In this embodiment, by providing the heating film 5, when applying alternating EP electroporation and EMS microcurrent functions to the skin, heat therapy can also be applied to the skin, meeting the diverse usage needs of users; and by providing the temperature sensor, the output temperature of the heating film can be sensed and fed back to the control circuit board 2, so that the control circuit board 2 can adjust the output temperature of the heating film according to the set temperature.

[0039] Furthermore, the device also includes a control button assembly 6, which is mounted on the housing assembly 1. The control button assembly 6 includes a power button 61, an electrical stimulation level adjustment button 62, and a temperature level adjustment button 63. The power button 61, electrical stimulation level adjustment button 62, and temperature level adjustment button 63 are all connected to the control circuit board 2. The power button 61 is used to turn the gua sha beauty device on and off. The electrical stimulation level adjustment button 62 is used to adjust the intensity of the output current of the EMS microcurrent circuit and the EP electroporation circuit. The temperature level adjustment button 63 is used to adjust the output temperature of the heating film 5. Specifically, the electrical stimulation level adjustment button 62 can adjust the intensity of the output current of the EMS microcurrent circuit and the EP electroporation circuit in 6 levels, and the temperature level adjustment button 63 can adjust the output temperature of the heating film 5 in 3 levels and turn off the heating film 5. In addition, several status indicator lights 64 are provided on the housing assembly 1 next to the control button assembly 6. The status indicator lights 64 are also connected to the control circuit board 2 and are used to indicate the working status of the gua sha beauty device.

[0040] Furthermore, it also includes several phototherapy lamp beads 7, which are disposed on the control circuit board 2. The light emitted by the several phototherapy lamp beads 7 passes through the massage head housing 31 and is emitted outward. Specifically, the massage head housing 31 is light-transmitting, while the electrode plates 32 are not. Therefore, the light emitted by the phototherapy lamp beads 7 is emitted outward from the massage head housing 31 between adjacent electrode plates 32. The light emitted by the phototherapy lamp beads 7 is red light, and the phototherapy lamp beads 7 and the heating film 5 are turned on and off simultaneously. In this embodiment, by setting the phototherapy lamp beads 7, phototherapy can also be performed on the skin when applying alternating EP electroporation function and EMS microcurrent function, further meeting the diverse usage needs of users.

[0041] Furthermore, it also includes a rechargeable battery 8, which is disposed in the housing assembly 1. The housing assembly 1 is provided with a charging interface 81, and both the rechargeable battery 8 and the charging interface 81 are connected to the control circuit board 2. Specifically, a protective soft cover (not shown in the figure) is also provided on the outside of the charging interface 81.

[0042] Furthermore, it also includes a protective cover 9, which can be placed over the outside of the scraping massage head 3 and is detachably connected to the housing assembly 1. The housing assembly 1 includes an inner housing 11 and an outer housing 12. The inner housing 11 has a mounting cavity 10, and the control circuit board 2 is disposed in the mounting cavity 10. The outer housing 12 is installed on the outside of the inner housing 11. In this embodiment, by providing the protective cover 9, the scraping beauty device can be covered when not in use to protect the scraping massage head 3 and facilitate carrying it with you. In addition, by providing the inner housing 11 and the mounting cavity 10 in the inner housing 11, it is possible to reasonably place various components. The outer housing 12 is also provided on the outside of the inner housing 11 to make the scraping beauty device more aesthetically pleasing overall.

[0043] The control circuit block diagram of the scraping beauty device in this utility model is as follows: Figure 8 As shown; however, the specific control circuit is existing technology and will not be described in detail here.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
