Description

Technical Field

[0001] The present invention relates to the technical field of massage and treatment, and in particular to an electrode head and a treatment device. Background Art

[0002] Facial and other skin care technologies include radiofrequency, ultrasound, phototherapy, and microcurrent. The working principle of radiofrequency is that the radiofrequency electrodes form a circuit with the skin, generating radiofrequency waves through the oscillation circuit. By adjusting the operating parameters of the radiofrequency, it can directly penetrate the skin and act on the tissue cells deep in the skin, achieving lifting and firming effects, promoting collagen regeneration, and hair regeneration.

[0003] Most existing RF devices are monopolar or bipolar. Their disadvantages are: 1) Existing RF devices have only one or two fixed electrodes. During treatment, the RF energy of monopolar RF is concentrated at a single point. Although bipolar RF is safer than monopolar RF, it still has strong noise points, and the current density at the two poles is high, generating high heat. 2) The supporting and fixing materials of the electrodes of existing RF therapy devices are plastic, which has poor thermal conductivity. During treatment, the RF energy emitted by the RF device interacts with the skin surface tissue, generating heat. The electrode surface temperature is high, and the surrounding material is plastic. The skin surface in direct contact with the RF head electrode will quickly accumulate heat and cannot dissipate, causing the surface skin tissue temperature to be too high, causing damage to the epidermal tissue cells. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an electrode head with good heat dissipation effect, good radio frequency effect and easy use.

[0005] Another technical problem to be solved by the present invention is to provide a therapeutic device having the above-mentioned electrode head.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is to provide an electrode head, which includes a support plate made of an insulating heat-conductive material, and the support plate has a heat-conducting surface for directly contacting the skin and a heat dissipation surface connected to the heat-conducting surface; a plurality of electrode plates arranged in an array are fixed on the heat-conducting surface of the support plate.

[0007] By adopting the electrode head of the above technical solution, multiple electrode sheets are arranged in an array and distributed on the heat-conducting surface of the support sheet. When in use, the heat-conducting surface of the support sheet and the multiple electrode sheets are directly in contact with the skin. The direct contact of the electrode sheets with the skin can ensure the best radio frequency effect. The support sheet is made of an insulating heat-conducting material, so the support sheet has good thermal conductivity. At the same time, the heat-conducting surface of the support sheet is in contact with the skin. Therefore, during treatment, the heat at the skin surface tissue and the heat generated by the electrode sheets can be efficiently and quickly diffused to the outside world or the heat dissipation surface through the heat-conducting surface. The heat dissipation surface can be designed to be exposed to the air so that the heat diffused to the heat dissipation surface can eventually be dissipated to the outside world, thereby ensuring that the skin surface tissue is not damaged due to excessive temperature. In addition, the array-arranged electrode sheets can form a more rigorous and delicate electric field, which can take care of the entire area of ​​the skin covered by the support sheet. The radio frequency energy is evenly applied to each area of ​​the covered skin, and the local area heat dissipation and cooling can be achieved by controlling the opening and closing of the electrode sheets in the local area.

[0008] As an improvement to the electrode head provided by the present invention, the support sheet has a mounting surface opposite to the heat-conducting surface; the mounting surface of the support sheet is concavely provided with multiple first airflow channels extending along a first direction; the first direction is perpendicular to the thickness direction of the support sheet; and the thickness direction is parallel to the direction from the side where the heat-conducting surface of the support sheet is located to the side where the mounting surface of the support sheet is located. It should be noted that in the prior art, the area behind the electrode sheet is usually a closed environment with poor heat dissipation effect, and the internal circuit itself generates heat, which exacerbates the difficulty of internal heat dissipation. However, through the above-mentioned improvement, multiple first airflow channels connected to the outside world are formed on the mounting surface of the support sheet (which can be understood as the back of the electrode sheet). The heat transferred from the skin surface tissue to the support sheet can not only be diffused to the outside world through the heat dissipation surface, but also be diffused to the outside world through the concave mounting surface. Moreover, during the treatment process, when the electrode head is moved, a fast-flowing airflow can be formed in the first airflow channel, and the convection of the air can quickly dissipate the heat of the support sheet, thereby enhancing the heat dissipation effect.

[0009] As an improvement to the electrode head provided by the present invention, the mounting surface of the support plate is recessed with multiple second airflow channels extending along a second direction; the second direction is perpendicular to the thickness direction; and each first airflow channel is cross-connected with multiple second airflow channels. This improvement forms multiple second airflow channels connected to the outside world on the mounting surface of the support plate, further enhancing the air convection effect on one side of the mounting surface of the support plate during movement of the electrode head, further improving heat dissipation efficiency.

[0010] As an improvement to the electrode head provided by the present invention, the heat dissipation device includes a plurality of heat sinks spaced apart along the extension direction of the first airflow channel. With this improvement, heat from the support plate is quickly absorbed by the heat sink and more efficiently diffused into the first airflow channel, thereby enhancing the heat dissipation effect of the support plate.

[0011] As an improvement to the electrode tip provided by the present invention, the heat dissipation device includes cooling tubes that are arranged in a curved, winding pattern and wound through the plurality of first airflow channels. With this improvement, the heat of the air within the first airflow channels can be removed by the cooling tubes, thereby rapidly reducing the temperature of the air within the first airflow channels. This allows the heat from the support plate to diffuse more quickly from the concave mounting surface to the first airflow channels, thereby enhancing the heat dissipation effect of the support plate.

[0012] As an improvement to the electrode head provided by the present invention, the support sheet has a plurality of wire holes that pass through the support sheet along the thickness direction, and the plurality of wire holes correspond one-to-one to the plurality of electrode sheets, and the wire holes are not connected to the first airflow channel. A wire is passed through each of the wire holes, one end of the wire is electrically connected to the corresponding electrode sheet, and the other end passes through the support sheet. Through the above improvements, each of the electrode sheets can be electrically connected to a matching signal generator through a relatively independent wire, which is beneficial to simplify the wire wiring of the electrode sheet and also beneficial to prevent the wiring harness from being entangled.

[0013] To solve another of the aforementioned technical problems, the present invention employs a technical solution to provide a therapeutic device comprising a housing and the electrode head described above, wherein the mounting surface of the support plate faces the housing and the support plate is mounted to the housing; a signal generator is disposed within the housing, and the multiple electrode plates on the electrode head are electrically connected to the signal generator. By employing the therapeutic device of the aforementioned technical solution, the heat dissipation surface of the support plate is exposed to the housing. Thus, during treatment, heat from the skin surface tissue can be efficiently and quickly diffused to the outside world through the support plate, ensuring that the skin surface tissue is not damaged.

[0014] As an improvement to the therapeutic device provided by the present invention, the housing further includes a switch circuit and a control unit electrically connected to the switch circuit; multiple electrode pads are electrically connected to the signal generator via the switch circuit; and the control unit controls at least one of the multiple electrodes to independently connect or disconnect with the signal generator via the switch circuit. With this improvement, the control unit can control the opening and closing of one or more electrode pads in a local area, thereby achieving targeted heat dissipation and cooling in that area.

[0015] As an improvement to the therapeutic device provided by the present invention, the support sheet has multiple wire holes extending through the support sheet along its thickness, each of which corresponds one-to-one to the multiple electrode sheets. A wire is passed through each of the wire holes, one end of which is electrically connected to the corresponding electrode sheet and the other end is electrically connected to the signal generator. With this improvement, each electrode sheet is electrically connected to the signal generator via its corresponding wire, which simplifies the wiring of the electrode sheets and prevents wire entanglement.

[0016] As an improvement to the therapeutic device provided by the present invention, a plurality of grooves extending along a first direction are provided on the side wall of the shell connected to the support sheet. Through the above improvement, the mounting surface of the support sheet will not be completely in contact with the shell, that is, a portion of the mounting surface will be exposed to the air, so that the heat transferred from the skin surface tissue to the support sheet can not only be diffused to the outside through the heat dissipation surface, but also diffused to the outside through the mounting surface. Moreover, during the treatment process, when the therapeutic device is moved, a fast-flowing airflow can be formed in the groove, and the convection of the air can quickly dissipate the heat of the support sheet, thereby enhancing the heat dissipation effect.

[0017] The implementation of the present invention can achieve at least the following beneficial effects:

[0018] 1. Multiple electrode sheets are arranged in an array on the heat-conducting surface of the support sheet. When in use, the heat-conducting surface of the support sheet and the multiple electrode sheets are directly in contact with the skin. The direct contact of the electrode sheets with the skin can ensure the best radio frequency effect;

[0019] 2. The support sheet is made of an insulating material with good thermal conductivity, so the support sheet has good thermal conductivity. At the same time, the heat-conducting surface of the support sheet is in contact with the skin. Therefore, during the treatment process, the heat on the skin surface tissue can be efficiently and quickly diffused to the outside world or the heat dissipation surface through the support sheet. The heat dissipation surface can be designed to be exposed to the air so that the heat diffused to the heat dissipation surface can eventually be dissipated to the outside world, thereby ensuring that the skin surface tissue is not damaged due to excessive temperature;

[0020] 3. The array of electrodes can form a more rigorous and delicate electric field, which can take care of the entire area of ​​the skin covered by the support sheet. The radio frequency energy is evenly applied to each area of ​​the covered skin, and the opening and closing of the electrode sheets in the local area can be controlled to achieve local heat dissipation and cooling;

[0021] 4. Multiple first airflow channels connected to the outside world are formed on the mounting surface of the support sheet (which can be understood as the back of the electrode sheet). The heat transferred from the skin surface tissue to the support sheet can be diffused to the outside world not only through the heat dissipation surface, but also through the concave mounting surface. Moreover, during the treatment process, when the electrode head is moved, a fast-flowing airflow can be formed in the first airflow channel, and the air convection can quickly dissipate the heat of the support sheet, thereby enhancing the heat dissipation effect.

[0022] 5. Each of the electrode sheets is electrically connected to the signal generator via a corresponding wire, which is beneficial to simplifying the wire wiring of the electrode sheets and also beneficial to preventing the wiring harness from being entangled. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] To facilitate understanding of the invention, the invention will be described more fully below with reference to the accompanying drawings. The drawings illustrate exemplary embodiments of the invention. However, the invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive disclosure of the invention.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the invention pertains. The terms used in the specification of the invention herein are for the purpose of describing specific embodiments only and are not intended to limit the invention.

[0037] Example 1

[0038] This embodiment provides a therapeutic device. Figure 1 , Figure 1 This is a structural diagram of the therapeutic device provided in this embodiment, wherein the therapeutic device includes a shell 2 and an electrode head 1 installed on the outside of the shell 2. The electrode head 1 includes a support plate 11 and a plurality of electrode plates 12 fixed on the support plate 11. Here, the support plate 11 is made of an insulating material with good thermal conductivity. Preferably, the support plate 11 is made of a ceramic material. The thermal conductivity of ceramic materials is generally above 20W / mK, or even as high as 200W / mK, while general plastics are mostly below 0.1W / mK. The thermal conductivity of ceramic materials is 200 or even 2000 times higher than that of general plastics. Therefore, the support plate 11 has good thermal conductivity. Figure 1 In the embodiment, the upward side of the support sheet 11 is the heat conducting surface 111, and the downward side is the mounting surface 112. The upper and lower side edges of the support sheet 11 are connected to the heat conducting surface 111 and the mounting surface 112 respectively, and the side surfaces thereof are the heat dissipation surfaces 113. The mounting surface 112 is fixedly connected to the housing 2, and the heat dissipation surface 113 is exposed to the housing 2. Here, a plurality of the electrode sheets 12 are arranged in an array and fixed on the heat conducting surface 111 of the support sheet 11, specifically in combination with Figure 2 , Figure 2This is a top view of the therapeutic device in this embodiment. As can be seen, the heat-conducting surface 111 of the support sheet 11 is flat, and the multiple electrode sheets 12 are arranged in an elliptical array on this surface. It can be understood that the multiple electrode sheets 12 in this embodiment are located on the same horizontal plane. During use of the therapeutic device, the heat-conducting surface 111 is in direct contact with the skin, ensuring optimal RF effect. Furthermore, during treatment, heat from the skin surface tissue and heat generated by the electrode sheets 12 can be quickly dissipated to the outside world or to the heat dissipation surface 113 through the heat-conducting surface 111. It should be noted that during movement of the therapeutic device, a portion of the heat-conducting surface 111 may be exposed to the air. In this case, heat from the skin surface tissue and heat generated by the electrode sheets 12 can be dissipated to the outside world through the heat-conducting surface 111. Furthermore, the array arrangement of the multiple electrode sheets 12 creates a more precise and precise electric field, covering the entire area of ​​skin covered by the support sheet 11, ensuring uniform application of RF energy to all areas of the covered skin. In addition, since the heat dissipation surface 113 is located on the periphery of the support sheet 11, it is exposed to the air during use. Therefore, during treatment, the heat from the skin surface tissue can be efficiently and quickly diffused to the outside world through the heat dissipation surface 113 of the support sheet 11, ensuring that the skin surface tissue is not damaged. Compared with ordinary single-electrode and dual-electrode skin beautification devices, the radio frequency head with a dot matrix arrangement has a more uniform energy distribution. At the same time, the support sheet 11 made of high thermal conductivity material can quickly dissipate heat, thus achieving a qualitative leap in protecting the epidermis. Figure 3 , Figure 3This is a schematic diagram of the circuit connection principle of the therapeutic device provided in this embodiment. The housing 2 is equipped with a signal generator, a switching circuit, and a control unit. Multiple electrode pads 12 are electrically connected to the signal generator via the switching circuit, and the control unit is electrically connected to the switching circuit. The signal generator is used to generate a therapeutic signal. Here, the therapeutic signal includes different types of electrical signals. It is understood that the signal generator is a type of power supply that outputs the electrical signal used for treatment. The switching circuit includes multiple switches, each of which is connected to one or more electrode pads 12. In addition, each electrode pad 12 is connected to at least one switch. In this way, a single switch can simultaneously control the connection or disconnection between one or more electrode pads 12 and the signal generator. The connection or disconnection between the same electrode pad 12 and the signal generator bracket can be controlled by different switches. The control unit is a microprocessor that controls the opening and closing states of the multiple switches in the switching circuit. Therefore, the control unit can control the independent connection or disconnection of at least one of the multiple electrodes with the signal generator through the switching circuit. In other words, the control unit can independently control the connection or disconnection between one or more electrode sheets 12 on the support sheet 11 and the signal generator. In this way, the control unit can control the opening and closing of one or more electrode sheets 12 in a local area, thereby achieving targeted heat dissipation and cooling in the local area.

[0039] Furthermore, the support sheet 11 has a plurality of wire holes that pass through the support sheet 11 along the thickness direction, and the plurality of wire holes correspond one-to-one to the plurality of electrode sheets 12; a wire is passed through each of the wire holes, one end of the wire is electrically connected to the corresponding electrode sheet 12, and the other end is electrically connected to the switching circuit. It should be noted that the thickness direction is parallel to the direction from the side where the heat conducting surface 111 of the support sheet 11 is located to the side where the mounting surface 112 of the support sheet 11 is located. In this way, each of the electrode sheets 12 is electrically connected to the signal generator through the corresponding wire, which is conducive to simplifying the wire wiring of the electrode sheet 12 and also helps to prevent the wire harness from being entangled.

[0040] In other embodiments, the support sheet 11 can also be made of other insulating materials with good thermal conductivity. For example, the industry uses a thermally conductive gasket TGP10000ULM specifically for improving thermal conductivity, and its thermal conductivity reaches 10W / m. It should be noted that in the industry, high thermal conductivity materials are mostly used in macroscopic structures, such as 5G transmitters, and are rarely used for cooling microstructures. Here, the thermally conductive gasket TGP is innovatively used in the manufacture of the support sheet 11 of the electrode head 1, which can achieve the purpose of improving the heat dissipation performance of the support sheet 11. Of course, the support sheet 11 can also be made of thermally conductive silicone sheets, thermally conductive insulating rubber, or graphene materials that have been insulated.

[0041] In other embodiments, the heat-conducting surface 111 of the support sheet 11 may be an arcuate surface, an annular surface, a curved surface, etc., and may be specifically designed according to the part to be treated.

[0042] In other embodiments, the multiple electrode sheets 12 on the support sheet 11 can be arranged in various shapes, such as a circular array, a rectangular array, a trapezoidal array, a triangular array, a ring array, a digital array, an alphabetical array, etc., and can also be an array in an irregular pattern, which can be specifically designed according to the part to be treated.

[0043] In other embodiments, the electrode head 1 is fixed in the housing 2 in an embedded manner. In this case, the heat dissipation surface 113 of the electrode head 1 is wrapped by the housing 2. Although this will reduce the heat dissipation performance to a certain extent, it can enhance the stability of the connection between the electrode head 1 and the housing 2. In this case, the heat conductive surface 111 of the electrode head 1 serves as the main heat dissipation path, and compared with the existing technology, it also has the advantage of high heat dissipation efficiency.

[0044] Example 2

[0045] The therapeutic device in this embodiment differs from the therapeutic device provided in the first embodiment only in that: the mounting surface 112 of the support sheet 11 is recessed with a plurality of first airflow channels 114 extending along a first direction; the first direction is perpendicular to the thickness direction of the support sheet 11; and the thickness direction is parallel to the direction from the side where the heat conducting surface 111 of the support sheet 11 is located to the side where the mounting surface 112 of the support sheet 11 is located. Figure 4 and Figure 5 , Figure 4 The structural diagram of the therapeutic apparatus provided in this embodiment is shown in FIG. Figure 4 In the figure, the first direction can be understood as a direction extending vertically from the outside of the paper to the inside of the paper; Figure 5 This is a bottom view of the electrode head 1 in the therapeutic device provided in this embodiment. Figure 4 and Figure 5As can be seen in FIG, a plurality of the first air flow channels 114 are arranged at equal intervals, and two adjacent first air flow channels 114 are separated by a support bar 115. When the support sheet 11 is mounted on the housing 2, only the bottom of the support bar 115 is in contact with the housing 2 (see FIG. Figure 4 ), so that the mounting surface 112 does not need to be completely connected to the shell 2. In other words, a portion of the mounting surface 112 is exposed to the air. Compared with the first embodiment, in this embodiment, a plurality of first air flow channels 114 connected to the outside world are formed at the mounting surface 112 of the support sheet 11. In this way, the heat transferred from the skin surface tissue to the support sheet 11 can not only diffuse to the outside world through the heat dissipation surface 113, but also diffuse to the outside world through the concave mounting surface 112. More importantly, during the treatment process, when the electrode head 1 is moved, a fast-flowing airflow can be formed in the first air flow channel 114, and the convection of the air can quickly dissipate the heat of the support sheet 11, thereby enhancing the heat dissipation effect.

[0046] Example 3

[0047] The therapeutic device in this embodiment differs from the therapeutic device provided in the second embodiment only in that: the mounting surface 112 of the support plate 11 is further provided with a plurality of second air flow channels 116 extending along a second direction; the second direction is perpendicular to the thickness direction; and each of the first air flow channels 114 is cross-connected with a plurality of the second air flow channels 116. Figure 6 , Figure 6 This is a schematic diagram of the electrode head 1 in the therapeutic device provided in this embodiment when viewed from above. The mounting surface 112 is provided with a first air flow channel 114 and a second air flow channel 116 that are staggered horizontally and vertically. Correspondingly, a plurality of support feet 117 arranged in an array are formed on the lower side of the support plate 11. When the support plate 11 is mounted on the shell 2, only the bottom of the support feet 117 is attached to the shell 2. In this way, the mounting surface 112 does not need to be completely connected to the shell 2. In other words, most of the mounting surface 112 will be exposed to the air. Compared with the second embodiment, firstly, the area of ​​the mounting surface 112 exposed to the air can be further increased, which can improve the heat dissipation effect of the support plate 11. In addition, the air convection effect on one side of the mounting surface 112 of the support plate 11 during the movement of the electrode head 1 can be further enhanced, thereby accelerating the flow and diffusion of hot air between the mounting surface 112 and the shell 2, and further improving the heat dissipation efficiency.

[0048] Example 4

[0049] The therapeutic apparatus in this embodiment differs from the therapeutic apparatus provided in the second embodiment only in that the heat dissipation device comprises a plurality of heat dissipation fins 13 arranged at intervals along the extending direction of the first air flow channel 114. Figure 7 , Figure 7 A schematic diagram of the electrode head 1 in the therapeutic device provided in this embodiment when viewed from above. Each of the first air flow channels 114 contains a row of multiple heat sinks 13 arranged at equal intervals. Here, the heat sink 13 can be made of a metal sheet with better thermal conductivity than the support sheet 11. In this way, the heat of the support sheet 11 can be quickly absorbed by the heat sink 13 and diffused more efficiently into the first air flow channel 114, thereby enhancing the heat dissipation effect of the support sheet 11. In order to reduce the obstruction of the heat sink 13 to the flow of gas in the first air flow channel 114, a plurality of air holes can be provided on the heat sink 13. At the same time, the height of the heat sink 13 is less than the height of the first air flow channel 114 (that is, the height of the support bar 115), which can further prevent the heat sink 13 from obstructing the flow of gas in the first air flow channel 114.

[0050] In some other embodiments, a plurality of rows of the heat sinks 13 may be disposed in the first air flow channel 114 , and a certain distance may be spaced between two adjacent rows of the heat sinks 13 .

[0051] Example 5

[0052] The difference between the therapeutic apparatus in this embodiment and the therapeutic apparatus provided in the second embodiment is that the heat dissipation device includes a cooling tube 14 that is bent and wound through the plurality of first air flow channels 114. Figure 8 , Figure 8 This is a schematic diagram of the electrode head 1 in the therapeutic device provided in this embodiment from a bottom view. The cooling tube 14 is in a continuous S-shape and is wound through the plurality of first air flow channels 114. The liquid inlet 141 and the liquid outlet 142 of the cooling tube 14 are respectively connected to a coolant supply device (not shown). The liquid flowing out of the liquid outlet 142 flows into the coolant supply device, and after heat exchange and cooling, flows back into the cooling tube 14 from the liquid inlet 141. During the flow of the coolant in the cooling tube, the heat of the air in the first air flow channel 114 can be taken away, thereby quickly reducing the temperature of the air in the first air flow channel 114, so that the heat of the support plate 11 can be more quickly diffused from the concave mounting surface 112 to the first air flow channel 114, thereby enhancing the heat dissipation effect of the support plate 11.

[0053] Example 6

[0054] The therapeutic device in this embodiment differs from the therapeutic device provided in the first embodiment only in that a plurality of grooves 21 extending in a first direction are provided on the side wall of the housing 2 connected to the support plate 11. Figure 9 , Figure 9 This is a schematic diagram of the structure of the therapeutic device provided in this embodiment. Figure 9As shown, since the upper side wall of the housing 2 is provided with a plurality of through grooves 21, when the support sheet 11 is mounted on the upper side wall of the housing 2, the mounting surface 112 of the support sheet 11 will not be completely in contact with the housing 2, that is, a portion of the mounting surface 112 will be exposed to the air, so that the heat transferred from the skin surface tissue to the support sheet 11 can not only diffuse to the outside through the heat conducting surface 111 and the heat dissipating surface 113, but also diffuse to the outside through the mounting surface 112. More importantly, during treatment, when the therapeutic device is moved, a fast-flowing airflow can be formed in the grooves 21, and the convection of the air can quickly dissipate the heat of the support sheet 11, thereby enhancing the heat dissipation effect.
