[0040] In order to explain in detail the technical content, technical steps, objectives and effects achieved by this application, the following is a detailed description in combination with the implementation methods and the accompanying drawings.

[0041] Figure 1 It is a three-dimensional exploded schematic diagram of an embodiment of the skin care component of the present application. Figure 2 It is a three-dimensional exploded schematic diagram of another embodiment of the skin care component of the present application.

[0042] like Figure 1 and Figure 2 The skin care component 10 includes a cold compress 100, a refrigerating element 200, a heat sink 300, an electrode head 400 and a first cover body 500. The cold compress 100 has a contact surface 100a and a conductive surface 100b. Optionally, the contact surface 100a is used to contact the skin part. The refrigerating side 210 of the refrigerating element 200 is thermally coupled with the conductive surface 100b of the cold compress 100 to be able to cool the cold compress 100. The heat sink 300 is thermally coupled with the heating side 220 of the refrigerating element 200 to be able to dissipate heat from the refrigerating element 200. The electrode head 400 is relatively fixed to the cold compress 100, and is used to discharge and heat the skin contact part. The first cover body 500 is used to fix the cold compress 100 and the refrigerating element 200 and the heat sink 300. Optionally, the cold compress 100 and the electrode head 400 can be combined with other parts of the skin care assembly 10 through the first cover 500 to form a complete contact beauty device. The cold compress 100 and the cooling element 200 are fixed through the first cover 500 and the heat sink 300, which is more convenient during assembly and installation.

[0043] When the skin care component 10 is working, the electrode head 400 discharges electricity, for example, generates radio frequency or microcurrent, and the current passes through the skin part to stimulate the skin part, so that the expected beauty effect can be achieved. Because the skin part is equivalent to a resistor, the temperature of the skin part will increase. In addition, the thermal coupling between the cold compress 100, the refrigeration part 200 and the heat sink 300 allows the heat generated by the skin part to be conducted from the cold compress 100 through the refrigeration part 200 to the heat sink 300 and then dissipated from the contact beauty device.

[0044] Optionally, the cold compress 100 is relatively fixed to the electrode head 400, and the refrigerating element 200 is located between the heat sink 300 and the cold compress 100, and a sandwich structure of the heat sink 300, the refrigerating element 200 and the cold compress 100 is formed. Optionally, the first cover body 500 fixes the cold compress 100 and the refrigerating element 200 in the heat sink 300, and the cold compress 100 and the electrode head 400 are in contact with the skin and are adjacent to each other. On the one hand, while the electrode head 400 discharges and heats the deeper skin part, the cold compress 100 provides a lower temperature environment through the refrigerating element 200, and then the cold compress 100 can timely cool the shallower skin part to provide a more comfortable touch for the skin part. On the other hand, fixing the cold compress 100 and the refrigerating element 200 in the heat sink 300 through the first cover body 500 can facilitate the assembly and installation of the contact beauty instrument. For example, when the cold compress 100 or the refrigerating element 200 in the contact type beauty device needs to be replaced, the first cover 500 only needs to be removed from the heat sink 300, and the cold compress 100 and the refrigerating element 200 can be removed from the contact type beauty device and replaced. During installation, the cold compress 100 and the refrigerating element 200 are fixed to the heat sink 300 in sequence through the first cover 500, which is simple and convenient.

[0045] When electric current passes through the skin, it will cause muscle contraction and movement, achieving a beauty effect. During the discharge process, the electrode head 400 increases the epidermal temperature and dermal temperature of the skin. The increase in skin temperature includes the heat generated by skin cells and the heat after the conversion of electrical energy. By setting the cold compress 100, the heat generated by the electrode head 400 stimulating the epidermis is reduced, the skin epidermis is cooled, and the cold compress calms the skin, avoiding burns caused by excessive temperature, reducing discomfort during use, and improving the comfort of contact beauty devices. The refrigeration component 200 cools the cold compress 100 so that the cold compress 100 can continue to cool the skin epidermis. The process of alternating hot and cold can also expand and contract the skin, enhance the breathing of the skin, and better stimulate the tightening and regeneration of collagen in the dermis while protecting the skin from damage, tightening the skin and improving the beauty effect.

[0046] Optionally, the skin part may be facial skin or arm skin, etc., the shallower skin part may be the epidermis, and the deeper skin part may be the dermis. When the electrode head 400 is working, the discharge may generate radio frequency or microcurrent, etc., thereby beautifying the skin part.

[0047] The heat generated by the electrode head 400 at the skin site is conducted to the cold compress 100 and contacts the skin site through the contact surface 100a of the cold compress 100, thereby cooling the epidermis through the cold compress 100. Among them, the conduction surface 100b of the cold compress 100 is thermally coupled with the cooling side 210 of the cooling element 200, and then the cold compress 100 is cooled by the cooling element 200, and absorbs the heat conducted by the cold compress 100. When the cooling element 200 is cooling, heat will be generated on the heating side 220 accordingly, and the heating side 220 of the cooling element 200 is thermally coupled with the heat sink 300, and then the heat generated by the cooling element 200 is conducted to the heat sink 300 and discharged from the contact beauty device through the heat sink 300. In the entire heat transfer process, reducing the reflux of heat in a short period of time can extend the time for the contact beauty device to maintain a temperature equilibrium state.

[0048] Optionally, the cooling side 210 of the cooling element 200 is thermally coupled with the conductive surface 100b of the cold compress 100, and the heat sink 300 is thermally coupled with the heating side 220 of the cooling element, and heat transfer or heat transfer connection can be achieved through heat transfer, heat convection or heat radiation, or any combination of the above three methods.

[0049] Please continue reading Figure 1 and Figure 2 , the first cover body 500 is provided with an opening 510. Optionally, the opening 510 of the first cover body 500 is provided corresponding to the cold compress 100, the size of the opening 510 in at least one radial direction is smaller than the size of the cold compress 100 in the radial direction, and the first cover body 500 presses the edge of the cold compress 100 toward the heat sink 300 through the edge of the opening 510, thereby fixing the cold compress 100 and the refrigeration element 200 in the heat sink 300.

[0050] Optionally, the planar size of the contact surface 100a of the cold compress 100 is equal to the planar size of the opening 510, and the planar size of the conduction surface 100b of the cold compress 100 is larger than the planar size of the opening 510. Then, when the conduction surface 100b of the cold compress 100 is thermally coupled with the cooling side 210 of the refrigeration component 200 and the heating side 220 of the refrigeration component 200 is thermally coupled with the heat dissipation component 300, one side of the first cover body 500 is placed in the contact surface 100a of the compress 100 through the edge of the opening 510, and then the edge of the opening 510 can press the edge of the conduction surface 100b of the cold compress 100 toward the heat dissipation component 300 in an axial direction, so that the first cover body 500 fixes the cold compress 100 and the refrigeration component 200 in the heat dissipation component 300. In the design of the skin care component 10, the cold compress 100 and the refrigeration component 200 have specific functions, and generally the manufacturing and processing processes are relatively complicated. By providing an opening 510 on the first cover body 500, the cold compress 100 and the refrigeration component 200 can be fixed in the heat dissipation component 300 with a simple structure, thereby saving the internal space of the skin care component 10, reducing the production difficulty, and reducing the production cost.

[0051] Figure 3 4 is a front structural diagram of the skin care assembly of the present application. Optionally, the electrode head 400 is arranged at the edge of the opening 510 of the first cover 500, and the number of the electrode heads 400 is at least two. Among them, at least two electrode heads 400 are arranged at intervals on the periphery of the contact surface 100a of the cold compress 100.

[0052] Optionally, see Figures 1 to 3 The electrode head 400 includes an end 410 and a mounting post 420. A mounting hole 100c that penetrates the entire cold compress 100 and corresponds to the size of the mounting post 420 is provided on the contact surface 100a of the cold compress 100. The mounting post 420 is provided through the mounting hole 100c, so that the electrode head 400 is installed on the cold compress 100. The mounting post 420 can be relatively fixed to the cold compress 100 through one end thereof close to the conductive surface 100b. For example, a thread is provided at one end of the mounting post 420 close to the conductive surface 100b, and the electrode head 400 can be fixed to the cold compress 100 with a screw nut. The electrode head 400 can also be relatively fixed to the cold compress 100 in other ways.

[0053] Optionally, the mounting post 420 penetrates the cold compress 100 and mounts the end 410 on the contact surface 100a of the cold compress 100. When the end 410 and the contact surface 100a contact the skin part and the end 410 starts to transmit electricity, the heat emitted by the skin part caused by the end 410 can be radially conducted to the surroundings through the contact surface 100a of the cold compress 100 located around it. Under this structural design, the contact surface 100a of the cold compress 100 can be designed to be small enough, while ensuring that the cooling effect is achieved, saving costs, and at the same time not causing a large area of ​​cold feeling in the skin contact part.

[0054] The electrode head 400 is installed in a relationship with the cold compress 100. Optionally, the electrode head 400 installed in the cold compress 100 can be distributed in the middle of the cold compress 100, or can be distributed along the circumference. The end 410 of the electrode head 400 and the contact surface 100a of the cold compress 100 are in contact with the skin part. Since the electrode head 400 is installed on the whole piece of cold compress 100, no additional installation structure is required. There will be no extra grooves, grooves or protrusions, edges and other structures to scratch the skin. Therefore, the electrode head 400 installed on the whole piece of cold compress 100 can take into account both comfort and heat transfer performance, making the contacted skin part more comfortable. During the operation of the skin care component 10, the end 410 of the electrode head 400 and the contact surface 100a of the cold compress 100 can stably contact the skin at the same time. Therefore, the electrode head 400 is directly installed on the cold compress 100, which can take into account both the comfort and conduction performance of the skin care component 10.

[0055] Optionally, the skin care component 10 includes at least two electrode heads 400, and at least two electrode heads 400 are arranged at intervals on the periphery of the cold compress 100. Optionally, at least one electrode head 400 is a negative electrode, and at least one electrode head 400 is a positive electrode. Optionally, the electrode heads 400 can be distributed on the cold compress 100 in a dotted manner, or in a linear manner. The distribution of the electrode heads 400 cannot be too dense, and the interval distribution allows the cold compress 100 to fully contact the skin while the end 410 of the electrode head 400 contacts the skin, so that the distance between the end 410 of the electrode head 400 is not too small to block the contact surface 100a of the cold compress 100, resulting in the contact surface 100a of the cold compress 100 between the end 410 being unable to contact the skin.

[0056] Optionally, a plurality of electrode heads 400 may be disposed on the cold compress 100, and the plurality of electrode heads 400 are arranged at intervals in the circumference direction of the polygon, for example Figure 3In the figure, the cold compress 100 is a square with arc chamfers, and four electrode heads 400 are arranged at the four arc chamfers respectively. The multiple electrode heads 400 can also be arranged in a radial shape (such as a flower shape or a star shape) on the polygon as a whole. The multiple electrode heads 400 can also be arranged in a linear shape or multiple linear shapes on the polygon.

[0058] Optionally, a first snap fastener 520 is fixed to the first cover 500. A second snap fastener 310 is fixed to the heat sink 300 and snap-connected with the first snap fastener 520, so that the first cover 500 can fix the cold compress 100 and the refrigeration component 200 on the heat sink 300. Optionally, the first cover 500 is a square cover with four sides, and the first snap fastener 520 can be fixed on at least one side. The heat sink 300 is also a square structure, and the second snap fastener 310 can be set on its side corresponding to the first snap fastener 520, and the first snap fastener 520 is buckled into the second snap fastener 310, so that the first cover 500 can be fixedly connected with the heat sink 300.

[0059] Optionally, a first snap-fit ​​component 520 is respectively provided on the first side surface 530 and the second side surface 540 of the first cover body 500, and a corresponding second snap-fit ​​component 310 is also respectively provided on the corresponding third side surface 320 and fourth side surface 330 of the heat sink 300, and the heating side 220 of the refrigeration component 200 is thermally coupled with the heat sink 300, and the cooling side 210 of the refrigeration component 200 is thermally coupled with the conductive surface 100b of the cold compress 100. Optionally, the planar size of the contact surface 100a of the cold compress 100 is the same as the size of the opening 510 of the first cover body 500. The first cover body 500 is mounted on the contact surface 100a through the opening 510, and the first fastener 520 is buckled into the second fastener 310, and then the first fastener 520 is clamped by the second fastener 310, and the first cover body 500 is pulled to provide an axial force along the skin care component 10, so that the first cover body 500 is fixed to the heat sink 300, and the first cover body 500 fixes the cold compress 100 and the refrigeration component 200 to the heat sink 300.

[0060] Optionally, the first fastener 520 may be a cantilever hook, and the second fastener 310 may be a fixing hole. The cantilever hook is used to fix the fixing hole and hook the fixing hole, so that the first cover 500 is fixed to the heat sink 300.

[0062] Alternatively, if Figures 4 to 6 As shown, the heat sink 300 has a thermal coupling surface 340 thermally coupled to the heat-generating side 220 of the refrigerating element 200, and both sides of the thermal coupling surface 340 are connected to the third side surface 320 and the fourth side surface 330.
