Description

Technical Field

[0001] This utility model relates to the field of beauty equipment technology, and in particular to a head body and beauty instrument. Background Technology

[0002] With the rapid development of medical aesthetics technology, it has become increasingly common to integrate electrostimulation beauty technology with other beauty techniques (such as microneedling, cryotherapy, and light therapy) onto the same beauty head. Therefore, through holes are set in the integrated beauty head to allow the beauty functional components to extend and directly contact the skin, while the electrodes are arranged circumferentially around the through holes. However, it is difficult to achieve a high energy density on the surface of a biological body. The reason is that to achieve a high energy density on the surface of a biological body, it is usually necessary to increase the applied voltage. However, the increase in voltage will simultaneously increase the intensity of the current introduced through the skin, leading to intolerance of the biological skin.

[0003] Therefore, there is an urgent need to research a head body, beauty head, and beauty device that integrates electrical stimulation beauty technology with other beauty technologies and can achieve high energy density on the surface of a living organism. Utility Model Content

[0053] In cryotherapy beauty heads, the contact method between the cryotherapy beauty head and the skin is to use the freezing medium or components to directly contact the skin. Therefore, this type of beauty head needs to be provided with through holes so that the freezing medium or device can extend and directly contact the skin. When the cryotherapy beauty head needs to integrate electrodes, the electrodes are usually arranged in a way that is uniformly arranged around the through holes in the circumference. However, it is difficult to achieve a high energy density on the surface of a biological body.

[0054] In electrotherapy beauty heads, to achieve a high energy density on the surface of a living organism, it is usually necessary to increase the applied voltage. However, the increase in voltage will simultaneously increase the intensity of the current introduced through the skin. Since the tolerance threshold of biological skin is limited, in order to avoid the risk of damage caused by excessive charge accumulation, the prior art has set multiple staggered array electrodes on the entire contact surface of the beauty head to form a focused electric field, which can achieve a high energy density on the surface of a living organism. However, in this prior art, since the through-hole structure is completely eliminated, the freezing component for direct contact with the skin cannot be integrated into the beauty head.

[0055] It is evident that there is currently a lack of technology that integrates staggered array electrodes onto a cryotherapy head. This invention provides a head body and a beauty device to solve the technical problem that existing cryotherapy heads and beauty devices cannot achieve high-energy-density electrical stimulation treatment on the skin surface.

[0056] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0057] Please see Figures 1 to 9 The present invention provides a head body comprising:

[0058] The housing 1 has a contact end 10 for contacting the skin, and the contact end 10 is provided with a first mounting through hole 100;

[0059] Circuit component 2 is mounted on housing 1;

[0060] Electrode assembly 3 is exposed at contact end 10 and electrically connected to circuit assembly 2. Electrode assembly 3 includes multiple positive electrodes 30 and multiple negative electrodes 31. Multiple positive electrodes 30 are arranged in an array around the outer periphery of the first mounting through hole 100, and multiple negative electrodes 31 are arranged in an array around the outer periphery of the first mounting through hole 100. Each positive electrode 30 is arranged adjacent to at least one negative electrode 31, and the positive electrode 30 and the adjacent negative electrode 31 form an electric field for discharging to the skin.

[0061] In the layout of this embodiment, since the head body is provided with a first mounting through hole 100, the first mounting through hole 100 can be used to install beauty function components for beauty functions other than electrodes; and since multiple arrayed positive electrodes 30 and negative electrodes 31 are installed on the outside of the first mounting through hole 100, that is, an array of dense electrodes is formed on the surface of the contact end 10, when the positive electrodes 30 and negative electrodes 31 discharge, each electrode can form a dense, relatively high-energy electric field on the contact end 10 under the low-energy power supply of the circuit component 2, which can perform high-energy-density electrical stimulation treatment on the skin surface.

[0062] In the operation of this embodiment, after the head body is connected to the beauty function components and the external power device, the beauty head composed of the head body can not only perform high-energy-density electrical stimulation treatment on the skin, but also perform composite beauty treatment on the skin except for the motor.

[0063] Compared to existing technologies, if only a single array of multiple electrodes is used, it can only perform high-energy-density electrical stimulation treatment on the skin, but cannot perform complex treatments on the skin. If electrodes are simply placed outside the through-hole, it can only perform cryotherapy on the skin, but cannot perform high-energy-density electrical stimulation treatment on the skin. In this solution, a first mounting through-hole 100 and positive electrodes 30 and negative electrodes 31 arranged in an array around it are provided, so that the head body can achieve both cosmetic function treatments other than electrodes and high-energy-density electrical stimulation treatment on the skin surface.

[0064] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 7 In one specific embodiment, both the positive electrode 30 and the negative electrode 31 are point electrodes. The densely arranged point electrodes will form a high electric field under low voltage, which will significantly improve the effect of electrical stimulation therapy.

[0065] Based on the above embodiments, a specific arrangement of the positive electrodes 30 is further provided. Multiple positive electrodes 30 are arranged to form multiple positive electrode columns 300. The multiple positive electrode columns 300 are parallel and / or perpendicular to each other. For example, on the contact end 10, the arrangement direction of the multiple positive electrode columns 300 is along the horizontal or vertical direction to form a parallel array. Alternatively, the arrangement direction of the multiple positive electrode columns 300 is perpendicular to each other and crosses by 90° to form an orthogonal array. Or, some of the multiple positive electrode columns 300 are parallel and others are perpendicular to each other to form an array where parallelism and perpendicularity coexist.

[0066] Based on the above embodiments, a specific arrangement of the negative electrode 31 is further provided. Multiple negative electrodes 31 are arranged to form multiple negative electrode columns 310. The multiple negative electrode columns 310 are parallel and / or perpendicular to each other. The arrangement principle of the multiple negative electrode columns 310 is the same as that of the multiple positive electrode columns 300, which will not be elaborated here.

[0067] Based on the above embodiments of positive electrode 30 and negative electrode 31, a specific arrangement of positive electrode 30 and negative electrode 31 is further provided. At least one column of negative electrode 310 is arranged between two adjacent columns of positive electrode 300 that are parallel to each other, and / or at least one column of positive electrode 300 is arranged between two adjacent columns of negative electrode 310 that are parallel to each other. For example, each column of positive electrode 300 has one column of negative electrode 310 on one side, and each column of negative electrode 310 has one column of positive electrode 300 on one side, forming an array of alternating positive and negative positive and negative arrangements. Alternatively, each column of positive electrode 300 has two columns of negative electrode 310 on one side, and each column of negative electrode 310 has one column of positive electrode 300 on one side, forming a positive-negative-negative-positive arrangement. The array is arranged in an alternating pattern, for example, with two columns of positive electrodes 300 on one side of each column of negative electrodes 310 and one column of negative electrodes 310 on one side of each column of positive electrodes 300, forming an array of alternating negative and positive electrodes, forming a cross-combined point array arrangement. In specific implementation, the positive and negative electrodes formed by the positive electrode columns 300 and negative electrode columns 310 are arranged more closely, further improving the regularity, controllability and upper limit of the electric field distribution, reducing the influence of electroporation caused by differences in physiological state of the skin at a smaller scale (such as wounds, scars, acne marks, etc.). At the same time, this design increases the speed at which the skin releases charge during the pulse interval during the application of the pulsed electric field, reducing the skin polarization phenomenon caused by charge accumulation.

[0068] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, in order to make the electric field intensity more uniform, the length of any positive electrode array 300 is matched with the length of at least one adjacent negative electrode array 310. For example, if a positive electrode array 300 is longer, then at least one of the two adjacent negative electrode arrays 310 is the same length as the positive electrode array 300; or, for example, if a positive electrode array 300 is shorter, then at least one of the two adjacent negative electrode arrays 310 is the same length as the positive electrode array 300. This length-matching design of the electrode arrays can make the electric field intensity more uniform and the electrical stimulation intensity more uniform.

[0069] It should be noted that in order to achieve the matching of the length of the positive electrode array 300 with the length of at least one adjacent negative electrode array 310, the adapted circuit must also be of the same length, that is, the length of the circuit connected to any positive electrode array 300 must match the length of the circuit connected to the adjacent negative electrode array 310.

[0070] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, to further enhance the uniformity of the electric field strength, multiple positive electrode arrays 300 form a first pattern on the contact end 10. Parts of the pattern on the first pattern are arranged symmetrically around the center of the first mounting through-hole 100, for example, as... Figure 2 and Figure 3 The multiple positive electrode rows 300 shown at both ends of the diagonal are arranged symmetrically with respect to the center of the first mounting through hole, as shown in the example. Figure 1 The plurality of positive electrode arrays 300 located on the left and right sides of the first mounting through hole 100 are arranged symmetrically with respect to the center of the first mounting through hole 100; and / or, the plurality of negative electrode arrays 310 form a second pattern on the contact end 10, and a portion of the pattern on the second pattern is arranged symmetrically with respect to the center of the first mounting through hole 100, which is the same as the arrangement of the plurality of positive electrode arrays 300, and will not be described in detail here.

[0071] The contact end 10 may form only the first pattern, only the second pattern, or both the first and second patterns simultaneously. Those skilled in the art can choose according to actual needs.

[0072] It should be pointed out that, from Figure 4 and Figure 5 The arrangement of circuit components can reflect the arrangement of multiple positive electrode rows and multiple negative electrode rows, such as... Figure 5 The circuits on the left and right sides of the circuit assembly shown are arranged symmetrically with respect to the center of the first mounting via, such that the first pattern formed by the plurality of positive electrode columns connected thereto is arranged at least partially symmetrically with respect to the center of the first mounting via, and the second pattern formed by the plurality of negative electrode columns connected thereto is arranged at least partially symmetrically with respect to the center of the first mounting via.

[0073] Based on the above embodiments, in one possible embodiment, such as Figure 1 and Figure 7As shown, multiple positive electrode arrays 300 and multiple negative electrode arrays 310 are arranged radially outward from the first mounting through hole 100. That is, with the first mounting through hole 100 as the center, multiple positive electrode arrays 300 are arranged radially outward, and multiple negative electrode arrays 310 are also arranged radially outward, so that the electric field radiation lines formed by both are the same, radiating or expanding outward from the center. This allows the current to diffuse evenly from the center to the surrounding skin tissue, avoiding the problem of edge electric field energy distortion and concentration caused by edge effects in traditional parallel electrodes.

[0074] The radial arrangement of the multiple positive electrode rows 300 and the multiple negative electrode rows 310 can be uniform, for example, the angle between two adjacent radial positive electrode rows 300 is the same as the angle between the next two adjacent radial positive electrode rows 300; the radial arrangement of the multiple positive electrode rows 300 and the multiple negative electrode rows 310 can be non-uniform, for example, the angle between two adjacent radial positive electrode rows 300 is not the same as the angle between the next two adjacent radial positive electrode rows 300, but the radial distribution can be maintained in general.

[0075] Based on the above embodiments, in one possible embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the multiple positive electrode arrays 300 and multiple negative electrode arrays 310 are symmetrically arranged with the first mounting through hole 100 as the center. That is, after the multiple positive electrode arrays 300 and multiple negative electrode arrays 310 on the upper side and left side of the first mounting through hole 100 rotate around the first mounting through hole 100, they coincide with the multiple positive electrode arrays 300 and multiple negative electrode arrays 310 on the lower side and right side of the first mounting through hole 100.

[0076] Based on the above embodiments, such as Figures 1 to 3 As shown, on adjacent and parallel positive electrode rows 300 and negative electrode rows 310, positive electrodes 30 and negative electrodes 31 are staggered along the parallel axis direction. That is, at the position between two positive electrodes 30, on the axis perpendicular to the row, there is a negative electrode 31 of the adjacent row located on the axis, so that the periphery of the positive electrode 30 except the edge is surrounded by negative electrodes 31, and the periphery of the negative electrode 31 except the edge is surrounded by positive electrodes 30, thereby making the arrangement density between the positive electrodes 30 and negative electrodes 31 higher and the resulting electric field strength higher.

[0077] It should be pointed out that, such as Figure 7As shown, in one embodiment, on adjacent and parallel positive electrode columns 300 and negative electrode columns 310, the positive electrode 30 and the negative electrode 31 are aligned along the parallel axis direction. That is, in the direction perpendicular to the positive electrode column 300, the positive electrode 30 on the positive electrode column 300 and the negative electrode 31 on the adjacent negative electrode column 310 are aligned in the same axial direction. However, the density and electric field are higher when they are staggered. Those skilled in the art can choose according to their needs.

[0078] Please refer to Figure 4 and Figure 5 In a specific embodiment, a feasible structure for the circuit assembly 2 is further provided. The circuit assembly 2 includes a first circuit piece 20 and a second circuit piece 21 plated on the contact end 10 of the housing 1. Along the direction from the contact end 10 to the opposite end of the housing 1 (the connection end connected to the mounting base), the projections of a plurality of positive electrodes 30 are all located on the first circuit piece 20, and the first circuit piece 20 is conductively fixedly connected to the plurality of positive electrodes 30. Along the direction from the contact end 10 to the opposite end of the housing 1, the projections of a plurality of negative electrodes 31 are all located on the second circuit piece 21, and the second circuit piece 21 is conductively fixedly connected to the plurality of negative electrodes 31. In a specific implementation, each positive electrode 30 and negative electrode 31 has a corresponding circuit piece to supply power to ensure the formation of an electric field.

[0079] In one embodiment, such as Figure 4 and Figure 5 As shown, both the first circuit piece 20 and the second circuit piece 21 are ring-shaped structures. The first circuit piece 20 and the second circuit piece 21 are arranged around the outer periphery of the first mounting through hole 100. The first circuit piece 20, the second circuit piece 21 and the first mounting through hole 100 can be arranged coaxially. The first circuit piece 20 is located on the side of the second circuit piece 21 adjacent to the first mounting through hole 100, or the second circuit piece 21 is located on the side of the first circuit piece 20 adjacent to the first mounting through hole 100. In specific implementation, the first circuit piece 20 and the second circuit piece 21 can be attached to the contact end 10. The first circuit piece 20 and the second circuit piece 21, which are arranged coaxially with the first mounting through hole 100, can make full use of the end face of the contact end 10, which can reduce cross-layer wiring and make as many electrical connections as possible with the positive electrode 30 and the negative electrode 31, providing an electrical connection structure basis for the densely arranged positive electrode 30 and negative electrode 31.

[0080] The arrangement and connection relationship of the first circuit piece 20, the second circuit piece 21, the positive electrode 30, and the negative electrode 31 are as follows: For example, the first circuit piece 20 is arranged on the side adjacent to the first mounting through hole 100, and the second circuit piece 21 is arranged on the side away from the first mounting through hole 100. The first circuit piece 20 is electrically connected to the positive electrode 30, and the second circuit piece 21 is electrically connected to the negative electrode 31. Alternatively, the first circuit piece 20 is arranged on the side away from the first mounting through hole 100, and the second circuit piece 21 is arranged on the side adjacent to the first mounting through hole 100. The first circuit piece 20 is electrically connected to the positive electrode 30, and the second circuit piece 21 is electrically connected to the negative electrode 31. The first circuit piece 20 is electrically connected to the negative electrode 31; for example, the first circuit piece 20 is arranged on the side adjacent to the first mounting through hole 100, and the second circuit piece 21 is arranged on the side away from the first mounting through hole 100. The first circuit piece 20 is electrically connected to the negative electrode 31, and the second circuit piece 21 is electrically connected to the positive electrode 30. Alternatively, the first circuit piece 20 is arranged on the side away from the first mounting through hole 100, and the second circuit piece 21 is arranged on the side adjacent to the first mounting through hole 100. The first circuit piece 20 is electrically connected to the negative electrode 31, and the second circuit piece 21 is electrically connected to the positive electrode 30. Those skilled in the art can choose according to their needs.

[0081] In addition, such as Figure 6 As shown, the first circuit piece 20 has a pin terminal 200, which is located on the side of the housing 1 away from the contact terminal 10; the second circuit piece 21 has a pin terminal 210, which is located on the side of the housing 1 away from the contact terminal 10. Each pin terminal is located on the back of the housing 1 to be electrically connected to an external power source independently. That is, the pin terminal protrudes and is located at the bottom of the housing 1, or extends from the side wall of the housing 1 to the bottom of the housing 1. In specific implementation, the pin terminal located at the bottom of the housing 1 is used to make electrical connection between the head body and the mounting base.

[0082] Based on the above embodiments, in this embodiment, the first circuit chip 20 includes two interconnected positive circuits, referred to as the first positive circuit 201 and the second positive circuit 202, and the second circuit chip 21 includes two interconnected negative circuits, referred to as the first negative circuit 211 and the second negative circuit 212. The first positive circuit 201, the first negative circuit 211, the second positive circuit 202 and the second negative circuit 212 are all comb-shaped circuits. The first positive circuit 201 and the first negative circuit 211 are arranged interlaced on the same end face, and the second positive circuit 202 and the second negative circuit 212 are arranged interlaced on the same end face to accommodate the arrangement of multiple positive electrodes 30 and negative electrodes 31.

[0083] Specifically, for the first positive circuit 201, such as Figure 4 and Figure 5As shown, the first positive circuit 201 is located on the upper right side. The first positive circuit 201 includes a first arc-shaped circuit body 2010 and a plurality of first straight circuit bodies 2011 arranged side by side along the circumference of the first mounting through hole 100. The first straight circuit bodies 2011 are connected to the positive electrode 30 in the corresponding area and the first arc-shaped circuit body 2010. The positions of the plurality of first straight circuit bodies 2011 corresponding to the positions of the plurality of positive electrodes 30 in the corresponding area form a comb-shaped circuit.

[0085] The length of the first linear circuit body 2011 is matched with the length of an adjacent second linear circuit body 2021 to adapt and achieve the matching of the length of the positive electrode column 300 with the length of at least one adjacent negative electrode column 310.

[0086] Specifically, for the second positive circuit 202, such as Figure 4 and Figure 5 As shown, the second positive circuit 202 is located on the lower left side. The second positive circuit 202 includes a third arc-shaped circuit body 2110 and a plurality of third straight circuit bodies 2111 arranged side by side along the circumference of the first mounting through hole 100. The length of the third straight circuit body 2111 matches the length of the adjacent fourth straight circuit body 2121. The third straight circuit body 2111 is connected to the positive electrode 30 in the corresponding area and the third arc-shaped circuit body 2110.

The third arc-shaped circuit body 2110 is arranged adjacent to the edge of the second mounting through hole 101, and the third arc-shaped circuit matches half of the outline of the second mounting through hole 101.

[0087] Specifically, for the second negative electrode circuit 212, such as Figure 4 and Figure 5As shown, the second negative electrode circuit 212 is located on the lower left side.

The fourth arc-shaped circuit body 2120 is arranged near the edge of the contact end 10, and the fourth arc-shaped circuit body 2120 matches half of the contour of the edge of the contact end 10.

[0088] The length of the third linear circuit body 2111 is matched with the length of an adjacent fourth linear circuit body 2121 to adapt and achieve the matching of the length of the positive electrode column 300 with the length of at least one adjacent negative electrode column 310.

[0089] It should be understood that, based on the above specific embodiments, in the embodiments of the first positive circuit 201 and the first negative circuit 211, a second straight circuit 2021 is provided between two adjacent first straight circuit bodies 2011, and / or a first straight circuit 2011 is provided between two adjacent second straight circuit bodies 2021. That is, the comb-shaped plurality of first straight circuit bodies 2011 will be interspersed with the comb-shaped plurality of second straight circuit bodies 2021 so that the first positive circuit 201 and the first negative circuit 211 are interspersed on the same plane; in the embodiments of the second positive circuit 202 and the second negative circuit 212, a fourth straight circuit 2121 is provided between two adjacent third straight circuit bodies 2111, and / or two adjacent fourth straight circuit bodies 2021 are interspersed with the first negative circuit 2021.

That is, the comb-shaped third linear circuit bodies 2111 are interspersed with the comb-shaped second linear circuit bodies 2021 so that the second positive electrode circuit 202 and the second negative electrode circuit 212 are interspersed on the same plane. Since the length of the first linear circuit body 2011 matches the length of an adjacent second linear circuit body 2021 and the length of the third linear circuit body 2111 matches the length of an adjacent fourth linear circuit body 2121, the length of the positive electrode array 300 matches the length of at least one adjacent negative electrode array 310. This makes the overall length of the positive and negative electrodes at the contact end similar, resulting in a more uniform electric field and uniform electrical stimulation intensity.

[0090] In other embodiments, such as Figure 8As shown, in this embodiment, the first circuit chip 20 includes a complete ring-shaped positive electrode circuit, and the second circuit chip 21 includes two negative electrode circuits, namely the first negative electrode circuit 211 and the second negative electrode circuit 212. The ring-shaped positive electrode circuit is arranged along the edge of the contact end 10, and the two negative electrode circuits are arranged along the edge of the first mounting through hole 100. The ring-shaped positive electrode circuit and the two negative electrode circuits also form a comb-like structure to be interlocked with each other to adapt to the arrangement of multiple positive electrodes 30 and negative electrodes 31. The description of the interlocking of the comb-like structure can be found above, and will not be repeated here.

[0091] Please refer to Figure 1 , Figure 4 and Figure 5 In one specific embodiment, to enhance the electrotherapy and achieve a combined therapeutic effect, the electrode assembly 3 further includes at least one third electrode 32 and at least one fourth electrode 33. That is, the number of third electrodes 32 and fourth electrodes 33 can be one, two, three, or even more. The third electrodes 32 and fourth electrodes 33 are arranged on opposite sides of the first mounting hole 100, both along the edge of the first mounting hole 100. All positive electrodes 30 and all negative electrodes 31 are located on the side of the third electrodes 32 and fourth electrodes 33 away from the first mounting hole 100. Specifically, the third electrode... The electric field formed by electrode 32 and the fourth electrode 33 can differ from the electric field formed by positive electrode 30 and negative electrode 31, allowing for independent power supply to the electrodes in each region. The current intensity is adjustable and controllable, enabling the electrode intensity in each region to form differentiated electric field intensities on the inner and outer sides as needed. This enriches the layers of electrical stimulation treatment and allows users to make free choices. For example, a first-intensity electric field can be formed in one region, and a second-intensity electric field can be formed in another region, thereby enabling precise treatment of different areas of the skin. Of course, the electric field intensities in the two regions can be the same, and those skilled in the art can choose according to their needs.

[0092] In this embodiment, as Figure 1 and Figure 5 As shown, both the third electrode 32 and the fourth electrode 33 are strip electrodes, which are arc-shaped and match the contour of the first mounting through hole 100. Both the third electrode 32 and the fourth electrode 33 are connected to the electrode sheet, which extends to the bottom of the housing 1 for external electrical connection. In specific implementation, the electrode adjacent to the first mounting through hole 100 is a strip electrode, and the electrode away from the first mounting through hole 100 is a point electrode. The strip electrode is closer to the skin area to be treated, causing overall muscle contraction in the skin area to be treated, while the outer point electrode can regulate the muscle contraction of the edge area of ​​the skin to be treated. For example, the inner strip electrode is used for overall facial skin tightening, while the outer point electrode is used for local wrinkles such as nasolabial folds. The current intensity can be adjusted in zones, and they work together to make the overall skin treatment effect better.

[0093] like Figure 1 and Figure 2 As shown, there is one third electrode 32 and one fourth electrode 33, which are arranged opposite to each other on both sides of the first mounting through hole 100. The third electrode 32 and the fourth electrode 33 respectively match the semi-circular contour of the first mounting through hole 100; as in another embodiment Figure 7 As shown, there are two third electrodes 32 and two fourth electrodes 33. The two third electrodes 32 are arranged on the same side, and the two fourth electrodes 33 are also arranged on the same side. The third electrodes 32 and the fourth electrodes 33 are also arranged on opposite sides of the first mounting through hole 100.

[0094] Based on the embodiments of the third electrode 32 and the fourth electrode described above, please refer to... Figure 4 and Figure 5 In one embodiment, the circuit assembly 2 further includes a third circuit piece 22 and a fourth circuit piece 23 plated on the contact end 10 of the housing 1; along the direction from the contact end 10 to the opposite end of the housing 1, the projections of the third electrodes 32 are all located on the third circuit piece 22, and the third circuit piece 22 is electrically and fixedly connected to a plurality of third electrodes 32; along the direction from the contact end 10 to the opposite end of the housing 1, the projections of the fourth electrodes 33 are all located on the fourth circuit piece 23, and the fourth circuit piece 23 is electrically and fixedly connected to a plurality of fourth electrodes 33; wherein, the first circuit piece 20 and the second circuit piece 21 are respectively used to connect to the first positive electrode and the first negative electrode, and the third circuit piece 22 and the fourth circuit piece 23 are respectively used to connect to the second positive electrode and the second negative electrode. In specific implementation, each positive electrode 30, negative electrode 31, third electrode 32 and fourth electrode 33 has a corresponding circuit piece to supply power to ensure the formation of an electric field.

[0095] In one embodiment, such as Figure 4 and Figure 5 As shown, both the third circuit piece 22 and the fourth circuit piece 23 are strip-shaped structures, and their structures match the shapes of the third electrode 32 and the fourth electrode 33. The third circuit piece 22 and the fourth circuit piece 23 are arranged opposite to each other around the first mounting through hole 100. The third circuit piece 22 and the fourth circuit piece 23 are both located on the side of the first circuit piece 20 and the second circuit piece 21 adjacent to the first mounting through hole 100. In specific implementation, the third circuit piece 22 and the fourth circuit piece 23 can also fit on the contact end 10, and can also reduce cross-layer wiring, providing an electrical connection structure basis for the densely arranged third electrode 32 and fourth electrode 33.

[0096] In addition, such as Figure 6As shown, the third circuit piece 22 has a pin terminal 220, which is located on the side of the housing 1 away from the contact terminal 10; the fourth circuit piece 23 has a pin terminal 230, which is located on the side of the housing 1 away from the contact terminal 10. Each pin terminal is independently electrically connected to an external power supply. That is, the pin terminal extends out and is located at the bottom of the housing 1, or extends from the side wall of the housing 1 to the bottom of the housing 1. In specific implementation, the pin terminal located at the bottom of the housing 1 is used to make electrical connection between the head body and the mounting base.

[0097] Please refer to Figure 1 As shown, in a specific embodiment, the head body also includes a color sensor 4, which is used to detect the color of the skin. The contact end 10 is also provided with a second mounting through hole 101, which is used to install the color sensor 4. When the color sensor 4 is installed in the second mounting through hole 101, the detection head of the color sensor 4 is exposed outside the second mounting through hole 101. In specific implementation, the color sensor 4 can detect the skin condition during treatment and reflect the current state of the skin through the depth of color. For example, if the skin is excessively red, the detection feedback from the color sensor 4 can help avoid overstimulating the skin and causing skin damage.

[0098] Please refer to Figures 1 to 7 As shown, in a specific embodiment, a feasible structure for the housing 1 is further provided. The housing 1 is a plastic housing 1, a glass housing 1, or a sapphire housing 1. That is, the designed head body can be one of a plastic housing 1, a glass housing 1, and a sapphire housing 1.

[0099] Based on the above embodiments, in this embodiment, as Figures 1 to 4 As shown, the plastic housing 1 is a hollow frustum-shaped structure. The circuit assembly 2 and electrode assembly 3 are directly fabricated on the top of the plastic housing 1 using LDS (Laser Direct Structuring) process. The pins of the circuit assembly 2 are located on the back of the plastic housing 1. Subsequently, a surface layer is sprayed using a spraying process to make the conductive impedance of the contact terminal 10 less than 1Ω, the surface salt spray test result above 96H, and the electrolysis resistance of the pulse circuit to 110V.

[0100] Based on the above embodiments, in this embodiment, as Figures 7 to 9 As shown, both the glass shell 1 and the sapphire shell 1 are hollow annular structures. The circuit assembly 2 and electrode assembly 3 are directly fabricated on the top of either the glass shell 1 or the sapphire shell 1 using a PVD (Physical Vapor Deposition) process. Figure 9As shown, the pins of the circuit assembly 2 extend along the sidewall of the glass housing 1 or the sapphire housing 1 to the back of the glass housing 1 or the sapphire housing 1. By using the glass housing 1 and the sapphire housing 1, the contact end 10 can bring a natural cooling sensation to the skin when it comes into contact with the skin.

[0101] The second aspect of this utility model provides a beauty device, comprising:

[0102] The mounting base is equipped with a beauty function component, which includes one of the following: a cryotherapy component, a microneedling component, and a light therapy component.

[0103] The first aspect is the head body, which is mounted on a mounting base. When the head body is mounted on the mounting base, the beauty function component is located within the first mounting through hole 100, and at least a portion of the structure of the beauty function component is exposed outside the head body.

[0104] An operating handle, on which a mounting base is installed.

[0105] In the operation of this embodiment, when the freezing component is installed in the first mounting hole 100, a synergistic combination of freezing and electrostimulation is formed on the beauty head. The electrostimulation generated by each electrode of the electrode component can open skin cells in the form of electroporation, promoting the absorption of cosmetics. However, electroporation is painful. The freezing effect of the freezing component can reduce the pain of electroporation. Moreover, the opening of cells by electroporation is reversible. Freezing can lock the cells after they are opened by electroporation, prolonging the cell closure time and promoting the absorption of skin care products. When the microneedle component is installed in the first mounting hole 100, a synergistic combination of microneedling and electrostimulation is formed on the beauty head. The microneedle component forms multiple micropores on the skin. The electroporation of the electrode component can further expand the micropores to promote the absorption of skin care products. The electrostimulation of the electrode component can also promote skin cell proliferation and repair, improving skin texture. When the light component is installed in the first mounting hole 100, a synergistic combination of light therapy and electrostimulation is formed on the beauty head. The light component can accelerate the absorption of skin care products applied to the skin. Combined with the electroporation of the electrode component, it can enhance the drug absorption efficacy.

[0106] It should be noted that electroporation mainly refers to applying electrical pulses to the skin using low-voltage current to form temporary micropores on the cell membrane, thereby temporarily increasing the skin's permeability. When the electrical pulses act on the skin, the electric field strength inside the cells reaches a certain level, which causes the lipid bilayer of the cell membrane to reorganize, forming aqueous channels, i.e., electropores. These channels allow cosmetic ingredients to pass through, thereby enabling active ingredients to penetrate deep into the skin and exert better effects.
