[0055] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0056] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0057] It should also be noted that the directional terms such as left, right, up, and down in this embodiment are merely relative concepts or are based on the normal use status of the product and should not be considered as restrictive.

[0058] like Figures 1 to 3 As shown, it is a schematic diagram of the radio frequency beauty instrument provided by the embodiment of the utility model. The radio frequency beauty instrument 100 includes a housing 11, a radio frequency electrode 20b, a cold compress component 30, and a heat dissipation component 40. The radio frequency beauty instrument 100 can be used for skin beauty care. The following mainly uses the radio frequency beauty instrument for whitening, skin rejuvenation, wrinkle removal, etc. as an example for exemplary description, but it does not mean that the radio frequency beauty instrument 100 in this embodiment is limited to skin rejuvenation, whitening, and wrinkle removal. The principle of the radio frequency beauty instrument is to reach the bottom layer of the skin through radio frequency and activate collagen. After using the radio frequency beauty instrument 100, the skin will become fuller, and the local skin may become red and swollen after use, which can be relieved by cold compress. The radio frequency beauty instrument 100 localizes tissue heating, prompts the subcutaneous collagen to shrink and tighten, and takes cooling measures on the skin surface at the same time. The dermis is heated while the epidermis maintains a normal temperature. The radio frequency beauty instrument 100 can heat the tissue, prompt the subcutaneous collagen to shrink, and take cooling measures on the skin surface at the same time to keep the dermis at a normal temperature.

[0059] The radio frequency electrode 20b is mounted on the housing 11 and is used to perform radio frequency electrical stimulation on the skin to be treated.

[0060] In one embodiment, a plurality of radio frequency electrodes 20b are provided, and the plurality of radio frequency electrodes can be arranged at intervals along a preset direction so as to perform radio frequency treatment on the skin.

[0061] The following mainly uses the example of a radio frequency beauty instrument 100 including a plurality of radio frequency electrodes 21 arranged at intervals for exemplary description.

[0062] The cold compress assembly 30 is used to apply cold compress to the skin to be treated.

[0063] In one embodiment, see also Figures 4 to 6 The cold compress assembly 30 includes a cold compress member 31 installed on the shell 11, and the cold compress member 31 is used to apply cold compress to the skin to be treated, that is, the cold compress assembly 30 applies cold compress to the skin to be treated through the cold compress member 31; of course, in other embodiments, the cold compress assembly 30 may also include a radio frequency electrode, that is, the radio frequency electrode is the cold compress member, so as to apply cold compress to the skin through the radio frequency electrode.

[0064] In one embodiment, see also Figures 4 to 6The heat dissipation component 40 is arranged in the shell 11, and the heat dissipation component 40 is used to dissipate heat for the cold compress component 30; the heat dissipation component 40 includes at least one heat pipe 41, at least one support member 43, and a heat sink assembly 42, the heat pipe 41 has an evaporation portion 411 and a condensation portion 412, the evaporation portion 411 of the heat pipe 41 is thermally connected to the cold compress component 30, and the condensation portion 412 of the heat pipe 41 is thermally connected to the heat sink assembly 42; one end of the support member 43 is connected to the cold compress component 30, and the other end is connected to the heat sink assembly 42, and the support member 43 is at least used to support the heat pipe 41.

[0065] It can be understood that the cold compress component 30 will generate more heat when working. In this way, the evaporation part 411 of the heat pipe 41 is thermally connected to the cold compress component 30, and the condensation part 412 is connected to the heat sink component 42. In this way, the heat pipe 41 can transfer the heat generated by the cold compress component 30 to the heat sink component 42, so as to utilize the heat sink component 42 for heat dissipation. Heat dissipation using the heat sink can improve the heat dissipation efficiency of the radio frequency beauty instrument; and due to the supporting effect of the support member 43 on the heat pipe 41, the structure of the heat dissipation component 40 is relatively stable, ensuring that the heat dissipation component 40 has stable heat dissipation performance, thereby ensuring that the heat dissipation performance of the radio frequency beauty instrument 100 is stable.

[0066] The cold compress 31 can be made of a crystal material, specifically sapphire, K9 glass, crystal glass, and any material that meets the requirement of good thermal conductivity. In this embodiment, the cold compress 31 is preferably made of sapphire crystal material. Optionally, the cold compress 31 can be a circular plate or a rectangular block. In this embodiment, the cold compress 31 is preferably a rectangular block.

[0067] Of course, the cold compress 31 may also be made of other heat-conducting materials, such as a metal part, a heat-conducting ceramic part, or a heat-conducting alloy part.

[0068] The cold compress 31 contacts the skin to cool the skin to relieve the burning pain of the skin. The cold compress 31 can be as low as zero degrees, which can really make the burned skin reach a temperature as close to the freezing point as possible, thereby relieving the burning pain of the skin, and short-term contact will not cause skin damage.

[0069] One end of the heat pipe 41 is an evaporation part 411, and the other end is a condensation part 412. When one end of the heat pipe 41 is heated, the cooling liquid inside the heat pipe 41 will evaporate rapidly, and the steam flows from one end to the other end under the pressure difference, and releases energy to condense into liquid again. The formed liquid flows back to the evaporation part 411 under the action of capillary force along the capillary porous material. In this way, the heat is transferred from one end of the heat pipe 41 to the other end, thereby continuously dissipating heat. The condensation part 412 of the heat pipe 41 is thermally connected to the heat sink assembly 42, and the heat is transferred to the heat sink assembly 42. The heat sink assembly 42 further improves the heat dissipation efficiency of the heat pipe 41.

[0070] In some embodiments, the cooling liquid inside the heat pipe 41 may optionally be cooling water. The cooling liquid can accelerate the heat conduction effect of the heat pipe 41 , so that the heat pipe 41 can continuously transfer heat to the heat sink assembly 42 , and the heat sink assembly 42 dissipates the heat.

[0071] Since the heat pipe 41 is relatively long, is a slender member, and has a hollow structure inside, in order to improve the structural strength of the heat pipe 41, a support member 43 may be provided to support the heat pipe 41. The support member 43 may be a solid non-hollow structure and be made of a hard metal material so that the support member 43 has sufficient structural strength to support the heat pipe 41.

[0072] In some embodiments, the support member 43 is a heat conductive member and is made of a material with good thermal conductivity, such as an aluminum alloy material, so as to improve the overall heat dissipation efficiency of the heat dissipation assembly 40 .

[0073] In some embodiments, at least one cold compress 31 is provided between any two adjacent RF electrodes 21 in a preset direction. In this way, at least a cold compress effect of alternating hot and cold can be formed, and the cold compress and beauty effects on the covered skin can be improved, and the user experience can also be improved.

[0074] In some embodiments, the RF electrode 20b and the cold compress assembly 30 are located at the head of the housing 11, the heat sink assembly 42 is located at the tail of the housing 11, and the heat pipe 41 and the support member 43 extend from the head of the housing 11 to the tail of the housing 11. In some embodiments, since the heat pipe 41 has a long length, the support member 43 can effectively support the heat pipe 43.

[0075] For example, the housing 11 has a head and a tail, the length direction of the housing 11 is from the head to the tail, the head and the tail are respectively located at the two ends of the length direction of the housing 11, the RF electrode 20b and the cold compress assembly 30 are both located at the head of the housing 11, the heat sink assembly 42 is located at the tail of the housing 11, and the heat pipe 41 and the support member 43 are both extended from the head of the housing 11 to the tail of the housing 11. It is worth noting that the extension of the heat pipe 41 and the support member 43 from the head of the housing 11 to the tail of the housing 11 here refers to their approximate position and approximate length, but does not mean that the length of the heat pipe 41 and the support member 43 must be the same as the length of the housing 11. The length of the support member 43 can be roughly the same as the length of the heat pipe 41, so that the support member 43 can provide a relatively stable support for the heat pipe 41.

[0076] In some embodiments, Figures 4 to 6As shown, the at least one heat pipe includes a first heat pipe 41a and a second heat pipe 41b, and the first heat pipe 41a and the second heat pipe 41b are arranged at intervals, and the support member 43 is arranged between the first heat pipe 41a and the second heat pipe 41b.

[0077] In this embodiment, two heat pipes 41 are provided, namely, a first heat pipe 41a and a second heat pipe 41b, the first heat pipe 41a and the second heat pipe 41b are arranged side by side, and the support member 43 is provided between the first heat pipe 41a and the second heat pipe 41b, and the opposite sides of the support member 43 can respectively abut against the side ends of the first heat pipe 41a and the second heat pipe 41b to stably support the first heat pipe 41a and the second heat pipe 41b. Of course, in other embodiments, the opposite sides of the support member 43 may not abut against the side ends of the first heat pipe 41a and the second heat pipe 41b, that is, a small gap is left between the support member 43 and the side ends of the first heat pipe 41a and the second heat pipe 41b, at which time the first heat pipe 41a and the second heat pipe 41b are allowed to have a small deformation, and the first heat pipe 41a and the second heat pipe 41b can still abut against the support member 43 after slight deformation, so that the support member 43 can also play a good supporting role.

[0078] In some other embodiments, a plurality of heat pipes 41 and a plurality of support members 43 are provided, and the plurality of heat pipes 41 are arranged at intervals, and a support member 43 is correspondingly provided between any two adjacent heat pipes 41 .

[0079] In this embodiment, the number of heat pipes 41 and the number of support members 43 are both multiple. For example, the number of heat pipes 41 is set to three, and the three heat pipes 41 are arranged side by side and spaced apart. A support member 43 is provided between any two adjacent heat pipes 41 among the three heat pipes 41, that is, the number of support members 43 is two, and the number of heat pipes 41 is one more than the number of support members 43, and so on. In this way, it can be ensured that each heat pipe 41 can be supported by the support member 43, thereby improving the overall stability of the heat dissipation assembly 40.

[0080] In some embodiments, see Figure 5 , Figure 6 The heat pipe 41 further includes a connecting section 413, which connects the evaporation section 411 and the condensation section 412. The connecting section 413 is disposed between the evaporation section 411 and the condensation section 412, and the evaporation section 411, the connecting section 413 and the condensation section 412 together constitute the heat pipe 41.

[0081] In some embodiments, the evaporation portion 411 and the connection section 413 are connected in a curved manner; the condensation portion 412 and the connection section 413 are connected; Figure 6As shown, the evaporation portion 411 and the connection section 413 are connected in a curved manner, and the condensation portion 412 is connected to the connection section 413. Accordingly, the support member 43 may also be configured as a curved structure, and the support member 43 bends along with the bending of the heat pipe 41, thereby ensuring the overall structural strength of the heat pipe 41. In other embodiments, it is understood that the condensation portion 412 and the connection section 413 may also be connected in a curved manner, and may be configured as required.

[0082] In other embodiments, Fig.13 As shown, the evaporation part 411 and the connection section 413 are connected by bending, and the condensation part 412 is connected to the connection section 413, and the connection section 413 can also be bent at least once. Accordingly, the support member 43 can be bent / bent along with the bending of the heat pipe 41. The bending or bending of the support member 43 and the heat pipe 41 is to better adapt to the shape change of the housing 11, especially when the housing 11 is an irregular shape, the space inside the housing 11 can be fully utilized by bending or bending the support member 43 and the heat pipe 41, thereby improving the space utilization rate and making the overall structure more compact.

[0083] In some embodiments, see Figure 1a The RF electrode 20b includes at least three RF electrodes 21 arranged at intervals along a first direction X (ie, a preset direction). The RF electrodes 21 are used to fit the skin to be treated. At least one cold compress 31 is provided between any two adjacent RF electrodes 21 in the first direction X.

[0084] In this embodiment, the first direction X may be a straight line direction, for example Figure 1a In the embodiment shown, the first direction X is a vertical straight line direction. However, the first direction X is not limited to a straight line direction, and the first direction X can also be along an arc direction or a circular direction, such as Figure 1b As shown, when the first direction X is along an arc, the RF electrodes 21 in the first direction X are arranged in a fan shape. When the first direction X is a ring direction, the RF electrodes 21 are arranged in a ring shape.

[0085] In some embodiments, the RF electrode 21 is a linear electrode, and the extension direction of the linear electrode is arranged at an angle with the first direction X; or, the RF electrode 21 is a ring electrode.

[0086] The extension direction of the linear electrode refers to the extension direction of the length of the electrode as a straight line direction. When the first direction X is a straight line direction, the angle between the extension direction of the length of the linear electrode and the first direction X can be an acute angle, an obtuse angle or a right angle. In some other embodiments, such as Figure 1c As shown, the radio frequency electrode 21 may also be a ring electrode.

[0087] In some embodiments, see Figure 1dThe RF electrode 21 includes a plurality of electrode units 21b spaced apart along its own extension direction; and / or, a cold compress 31 is provided between any two adjacent RF electrodes 21 in the first direction X, and the extension direction of the cold compress 31 is consistent with the extension direction of the linear electrode.

[0088] The structure of the radio frequency electrode 21 can be an independent integral structure or a component structure. When it is a component structure, Figure 1d As shown, the RF electrode 21 includes a plurality of electrode units 21b arranged along its own extension direction. Among the plurality of RF electrodes 21, a cold compress 31 is arranged between any two adjacent RF electrodes 21 to cool the skin. Since the RF electrodes 21 generate a lot of heat when working, a cold compress 31 is arranged between every two adjacent RF electrodes 21 to avoid heat concentration, which is conducive to balanced and efficient heat dissipation, thereby giving users a better experience.

[0089] In some embodiments, the working surface of the RF electrode 21 in contact with the skin to be treated is flush with the side of the cold compress 31 facing the skin to be treated, or the working surface of the RF electrode 21 in contact with the skin to be treated protrudes from the side of the cold compress 31 facing the skin to be treated.

[0090] The working surface of the RF electrode 21 in contact with the skin to be treated is made flush with the side of the cold compress 31 facing the skin to be treated, or the working surface of the RF electrode 21 in contact with the skin to be treated protrudes from the side of the cold compress 31 facing the skin to be treated. The purpose is to make the RF electrode 21 contact with the skin to be treated over as large an area as possible and maintain good fit, thereby ensuring the care effect of the RF electrode 2121.

[0091] In some embodiments, the shapes of the RF electrodes 21 are the same or different; and / or, the number of the RF electrodes 21 is three, four, five or six.

[0092] The shapes of the RF electrodes 21 are not limited, and the shapes of the RF electrodes 21 can be the same or different. The number of the RF electrodes 21 is also not limited, and the number of the RF electrodes 21 can be as follows: Figure 1a In the illustrated embodiment, the number of the plurality of radio frequency beauty devices 100 is three, and may also be four, five, six, or more than six. The number of the plurality of radio frequency beauty devices 100 may be selected based on the actual situation such as the area of ​​the skin to be treated and the shape of the radio frequency beauty device 100.

[0093] In some embodiments, see Figure 1a Among the plurality of RF electrodes 21 arranged at intervals in the first direction X, the two outermost RF electrodes 21 have the same shape, and the shapes of the two outermost RF electrodes 21 are different from those of the other RF electrodes 21 .

[0094] In this embodiment, the first direction X is a vertical straight line direction. At this time, the two outermost RF electrodes 21 refer to the two RF electrodes 21 located at the bottom and the top on the vertical straight line. In this embodiment, the two outermost RF electrodes 21 have the same shape, which means that the two RF electrodes 21 located at the bottom and the top have the same shape. The shapes of these two RF electrodes 21 are different from those of other RF electrodes 21. For example, Figure 1a In the embodiment in FIG. 1 , the width of the middle RF electrode 21 is significantly wider than the widths of the two RF electrodes 21 located at the bottom and the top.

[0095] In some embodiments, Figure 1e As shown, among the multiple RF electrodes 21 arranged at intervals in the first direction X, the two outermost RF electrodes 21 are first electrodes 21a, and the side of one first electrode 21a away from the other first electrode 21a is arc-shaped; and / or, the working surface of one first electrode 21a is at least partially gradually curved backward in the direction away from the other first electrode 21a.

[0096] like Figure 1e In the embodiment, the two outermost RF electrodes 21 are respectively located at the bottom and the top, and the side of the top first electrode 21a away from the bottom first electrode 21a is arc-shaped. This arrangement allows the first electrode 21a to smoothly contact the skin to be treated, thereby giving the user a better experience. Figure 1f As shown, in other embodiments, the working surface 211 of the first electrode 21a located at the uppermost end includes a straight portion 2111 and a curved portion 2112, wherein the curved portion 2112 is gradually curved toward the rear side of the RF electrode 21 in a direction away from the RF electrode 21 located at the bottom, so as to ensure that the first electrode 21a is in smooth contact with the skin to be treated during operation, thereby improving the user experience, and also increasing the contact area between the first electrode 21a and the skin to be treated to a certain extent, thereby improving the care efficiency.

[0097] In some embodiments, see Figure 4 , Fig.11 The shell 11 is provided with an air inlet 113 and an air outlet 114. A fan 44 is provided inside the shell 11. The fan 44 is used to drive wind to flow between the air inlet 113, the heat sink assembly 42 and the air outlet 114 to achieve gas exchange inside and outside the shell 11 to improve the heat dissipation effect.

[0098] For example, see Figure 4 , Fig.11The fan 44 has an air inlet and an air outlet. The air inlet of the fan 44 is opposite to the air inlet 113 on the housing 11, and the air outlet of the fan 44 faces the heat sink assembly 42. The fan 44 dissipates heat for the components in the housing 11. The fan 44 can perform the heat dissipation function independently or together with the heat sink assembly 40. The fan 44 can be fixed to the inner side of the housing 11 (such as Figure 4 As shown), support ribs and other components are provided on the inner side of the housing 11 to support the fan 44. Figure 4 and Figure 6 In this embodiment, one end of the support member 43 close to the heat sink assembly 42 is pressed against the heat sink assembly 42, so that the heat on the support member 43 can be transferred to the heat sink assembly 42, thereby preventing the temperature of the support member 43 from being too high.

[0099] In other embodiments, see Fig.11 A fan bracket 13 is provided in the housing 11, and the fan bracket 13 is used to install the fan 44. One end of the support member 43 close to the heat sink assembly 42 is fixed to the fan bracket 13. That is, in this embodiment, the fan bracket 13 can be used not only to install and fix the fan 44, but also to install and fix the support member 43.

[0100] In this embodiment, the fan bracket 13 is a square frame structure, and the heat sink assembly 42 can also be installed in the fan bracket 13. The heat sink assembly 42 includes a plurality of heat sinks arranged side by side, and the gaps between adjacent heat sinks form the air passages. The air outlet of the fan 44 is connected to each air passage so that the refrigerant flows into the gaps between the heat sinks to dissipate heat from the heat sinks. The air outlet side of the heat sink assembly 42 can be set according to specific circumstances, which will not be described in detail here.

[0101] In some embodiments, see Fig. 9 , the radio frequency beauty instrument 100 also includes a circuit board assembly 50, which includes a first control board 51, a second control board 52, a radio frequency circuit board 53, and a key board 54. The first control board 51, the second control board 52, the radio frequency circuit board 53, and the key board 54 enclose a receiving cavity, and the heat pipe 41 is arranged in the receiving cavity. Among them, the first control board 51 can at least be used to control the operation of the fan 44, the radio frequency circuit board 53, the cooling plate 32 and other components, the second control board 52 can be set as a main control board, and the second control board 52 is integrated with a control chip. The radio frequency electrode 21 is electrically connected to the radio frequency circuit board 53. The radio frequency circuit board 53 is mainly used to form a radio frequency generating circuit, such as a boost circuit, pulse adjustment, etc.; the key board 54 is used to control the key. This arrangement can make full use of the space in the housing 11, improve the utilization rate of the space, and also make the overall structure of the radio frequency beauty instrument 100 more compact, avoiding the radio frequency beauty instrument 100 from being too large.

[0102] In some embodiments, see Fig. 9 As shown, the radio frequency beauty instrument 100 also includes a display panel 56 located on the same side of the radio frequency beauty instrument 100 as the key panel 54, and the display panel 56 is arranged at an angle with the key panel 54. The display panel 56 is used to display the working mode of the radio frequency beauty instrument 100 and provide users with relevant reminder functions to enhance the intelligence and experience of the radio frequency beauty instrument 100. In addition, the display panel 56 and the key panel 54 are located on the same side of the radio frequency beauty instrument 100, which fully utilizes the internal space of the radio frequency beauty instrument 100 and improves the utilization rate of the space.

[0103] In some embodiments, see Figure 2 A battery 60 is also provided in the housing 11, and the battery 60 is used to store electrical energy for the radio frequency beauty instrument 100, so that the radio frequency beauty instrument 100 can be used independently, and it is also convenient for the user to carry it when going out.

[0104] In some embodiments, see Figure 2 , Fig. 9 The housing 11 includes a first shell 111 and a second shell 112 connected to the first shell 111 . The cold compress 31 and the radio frequency electrode 20 b are installed in the first shell 111 . The heat pipe 41 , the support member 43 and the heat sink assembly 42 are all arranged in the second shell 112 .

[0105] The first shell 111 is located at the head of the housing 11, one end of the cold compress 31 is installed on the first shell 111, the RF electrode 20b is installed on the first shell 111, and the second shell 112 is also used for human hand holding, and the second shell 112 is in a long strip shape. Both the first shell 111 and the second shell 112 can be made of plastic material.

[0106] In some embodiments, see Figure 2 , Figure 3The first shell 111 includes a substrate 110 and a surrounding plate 1115 arranged at the periphery of the substrate 110. The substrate 110 is provided with an electrode mounting hole 1111 and a cold compress hole 1114. The RF electrode 21 is inserted into the electrode mounting hole 1111. After the RF electrode 21 is inserted into the electrode mounting hole 1111, the RF electrode 21 protrudes from the outer surface of the substrate 110, so that the RF electrode 21 can quickly contact the skin to be treated during operation, and can also adjust the contact area with the skin to a certain extent. For example, the corner of the RF electrode 21 can contact the skin to be treated with a smaller area to adapt to the skin part that needs small area contact care. The cold compress 31 is inserted into the cold compress hole 1114. After the cold compress 31 passes through the cold compress hole 1114, the cold compress 31 protrudes from the outer surface of the substrate 110, so that it can quickly contact the skin to be treated during operation, and can also improve the fit with the skin, so that the cold compress effect is better. An installation opening 1121 is formed at one end of the second shell 112, and the enclosure 1115 of the first shell 111 is installed at the installation opening 1121; the first shell 111 and the second shell 112 can be integrally formed, or can be a split structure. When the first shell 111 and the second shell 112 are a split structure, the first shell 111 and the second shell 112 can be fixedly connected or detachably connected. The first shell 111 and the second shell 112 can be snap-fitted or fastened by fasteners such as screws. The first shell 111 is used to install the radio frequency electrode 21 and the cold compress 31, and the second shell 112 can be in the shape of a square cylinder, a long strip, etc. The second shell 112 is used for being held by hand, and can also be used to install a control panel, buttons, etc.

[0107] In other embodiments, see Figures 8 to 11As shown, the housing 11 includes a first housing 111 and a second housing 112 connected to the first housing 111. The first housing 111 includes an end cover 1112 and a first extension 1113 extending from the end cover 1112 toward one side of the second housing 112. An angle is formed between the first extension 1113 and the end cover 1112. The second housing 112 includes a handheld portion 1122 and a second extension 1123 extending from the handheld portion 1122 toward one side of the first housing 111. An angle is formed between the second extension 1123 and the handheld portion 1122. The side edge of the first extension 1113 is butted against the side edge of the second extension 1123. In this embodiment, the first housing 111 and the second housing 112 are not of regular shape, but are both arranged in a bent state. In this embodiment, the first extension portion 1113 and the end cover portion 1112 are set at an obtuse angle, the hand-held portion 1122 and the second extension portion 1123 of the second shell 112 are set at an obtuse angle, and after the first shell 111 and the second shell 112 are connected, the shell 11 is bent as a whole. In this way, when using, the user does not need to raise the hand to a higher height or bend the wrist to a larger angle to make the radio frequency electrode 21 close to the skin to be treated, which is more in line with ergonomic principles. At the same time, it is also more convenient for the operator to adjust the use angle, which saves time and is convenient.

[0108] In some embodiments, Figure 1 As shown, the length direction of the first shell 111 is consistent with the length direction of the second shell 112. The first shell 111 is located in the extension direction of the length of the second shell 112, and the first shell 111 and the second shell 112 are coaxially arranged. The radio frequency beauty instrument 100 of this structure is simple in shape and easy to process.

[0109] In some embodiments, see Figure 1 The cross-sectional area of ​​the first shell 111 is smaller than the cross-sectional area of ​​the second shell 112. The cross-sectional area of ​​the first shell 111 is smaller than the cross-sectional area of ​​the second shell 112, so that when the use angle of the radio frequency electrode 21 is adjusted when the radio frequency beauty instrument 100 is used, the problem of interference and inconvenience caused by the excessive volume of the second shell 112 can be avoided.

[0110] In some embodiments, see Figure 4 , Fig.11The cold compress assembly 30 also includes a cooling sheet 32, the cooling surface of the cooling sheet 32 ​​is thermally connected to the cold compress 31, and the thermally conductive surface of the cooling sheet 32 ​​is thermally connected to the heat dissipation assembly 40; the cooling sheet 32 ​​can be a TEC semiconductor temperature difference cooling sheet, and during the operation of the cooling sheet 32, as long as there is a temperature difference between the cold end of the cooling sheet 32 ​​and the hot end of the cooling sheet 32, the heat is continuously transferred, and the heat is moved to the hot end of the cooling sheet 32 ​​and dissipated through the heat dissipation assembly 40. Therefore, the cooling sheet 32 ​​is an active cooling device for the cold compress 31, and an active heat conduction device for the entire device.

[0111] See also Figure 2 , Figure 4 , a mounting bracket 12 is provided in the outer shell 11, and the cold compress 31 and the refrigeration sheet 32 ​​are both installed on the mounting bracket 12; a cold compress mounting groove 121 for mounting the cold compress 31 and a refrigeration sheet mounting groove 122 for mounting the refrigeration sheet 32 ​​are provided on the mounting bracket 12, and the cold compress mounting groove 121 is communicated with the refrigeration sheet mounting groove 122. The mounting bracket 12 is provided in the inner cavity of the outer shell 11, and the mounting bracket 12 can be made of plastic material. The mounting bracket 12 is used to install the cold compress 31, the refrigeration sheet 32 ​​and other components in the outer shell 11.

The side light source 55 includes phototherapy lamp beads and phototherapy plates with phototherapy functions. The working principle of the phototherapy lamp beads is to use light of a specific wavelength to act on the skin, stimulate the mitochondria in the skin cells, and trigger the production of cellular energy (ATP). This energy activates skin cells, promotes cell repair and regeneration, and thus improves skin quality. Phototherapy lamp beads are commonly used in the fields of beauty, phototherapy, and manicure, and different lamp bead models and specifications can be selected according to different needs.

[0113] In some embodiments, see Fig.14 , the mounting bracket 12 is provided with a light board mounting groove 123 for mounting the side light source 55, and the light board mounting groove 123 is connected with the cold compress mounting groove 121. That is, in the present embodiment, the side light source 55 is mounted on the light board mounting groove 123 on the mounting bracket 12. During installation, the phototherapy board of the side light source 55 can be fixed to the mounting bracket 12 by fasteners such as screws, and the phototherapy lamp beads face the side of the cold compress 31, and the light emitted by the phototherapy lamp beads is emitted through the cold compress 31 to the skin to be treated. The mounting bracket 12 is also provided with a light guide hole 124, and the light guide hole 124 is connected with the light board mounting groove 123. The light guide hole 124 is used for the light emitted by the phototherapy lamp beads to pass through and illuminate the cold compress 31, and then be emitted through the cold compress 31 to the skin to be treated.

[0115] The heat-conducting fixture 33 is located on the side of the mounting bracket 12 facing away from the cold compress 31. The heat-conducting fixture 33 is in contact with the side of the cooling plate 32 facing away from the cold compress 31 (i.e., the heat-conducting surface). The heat-conducting fixture 33 is made of a metal material with good thermal conductivity, such as aluminum. The heat-conducting fixture 33 is also used to fix the heat pipe 41. The end of the heat pipe 41 close to the head of the radio frequency beauty instrument 100 is fixed on the heat-conducting fixture 33. Accordingly, the heat-conducting fixture 33 is provided with a fixing groove (not shown in the figure) for fixing the heat pipe 41. It is worth noting that part of the heat pipe 41 is accommodated in the fixing groove and part is exposed outside the fixing groove, which can help the heat pipe 41 to better play the role of evaporation and condensation.

[0116] In some embodiments, see Fig.11 The shell 11 is provided with an air inlet 113 and an air outlet 114. The air inlet 113 on the shell 11 is opposite to the air inlet of the fan 44.

[0117] The air inlet 113 on the housing 11 allows fresh air from outside the housing 11 to enter the housing 11. After entering the housing 11, the fresh air exchanges heat with the heat-generating components (such as the heat sink assembly 42, the support member 43, the heat pipe 41, the electronic components, etc.) in the housing 11 to become hot air, and then is discharged from the air outlet 114. This cycle continues, and the heat in the housing 11 can be continuously discharged. In this embodiment, the air outlet 114 is located at the rear of the housing 11, at the end surface of the end facing away from the cold compress 31 and the radio frequency electrode 21, and the air inlet 113 and the air outlet 114 both include a plurality of small holes arranged in an array.
