Detailed Description of the Embodiments

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0036] In view of the problems existing in the prior art, an embodiment of the present utility model provides an electrode mechanism. Refer to Figure 1 , the electrode mechanism includes: a circuit board 110, a conductive circuit 120, an electrode assembly 130, and a cooling assembly 140. The circuit board 110 is provided with the conductive circuit 120 and the electrode assembly 130. The electrode assembly 130 is connected to the conductive circuit 120. The electrode assembly 130 is used to contact the skin to input energy to the skin. The cooling assembly 140 is disposed on the circuit board 110 corresponding to the electrode assembly 130. The cooling assembly 140 and the electrode assembly 130 are respectively located on opposite sides of the circuit board 110. The cooling assembly 140 is used to cool down the electrode assembly 130.

[0037] When the electrode assembly 130 outputs high energy, the electrode assembly 130 will generate relatively high heat. In this solution, the cooling assembly 140 is provided corresponding to the electrode assembly 130 to cool down the electrode assembly 130, effectively avoiding the problem of damaging the skin due to the too high temperature of the electrode assembly 130, improving the safety of use, and thus breaking the bottleneck of restricting energy output due to fear of skin burns in the past. The electrode assembly 130 can safely output higher energy. The high energy can penetrate the epidermis and reach the dermis layer or even deeper tissues, deepening the depth and scope of skin treatment, increasing the temperature of the deep layer of the skin (within the safe temperature range), improving the effectiveness of treatment, and greatly shortening the treatment time under the same treatment effect. After the electrode assembly 130 is cooled down, the skin surface temperature can also be maintained within a comfortable range, improving the comfort of the user.

[0038] In a specific embodiment, the electrode assembly 130 can be a monopolar radiofrequency electrode, a bipolar radiofrequency electrode, a multi-polar radiofrequency electrode, or any other electrode structure with radiofrequency function. For example, Figure 1 the bipolar radiofrequency electrode is adopted in the embodiment shown. To make the skin-adhering performance better, the electrodes can be selected with different shapes, arrangement modes, and densities according to the characteristics of the body part, which are not specifically limited herein. For example, the electrodes can be in the shape of dots, strips, or bands, etc. The electrode assembly 130 outputs radiofrequency energy for skin treatment.

[0039] In an embodiment, refer to Figure 1 and Figure 3, the cooling component 140 includes a bottom plate 141 and a housing 142. A cavity 143 is formed by enclosing with the bottom plate 141 and the housing 142. The bottom plate 141 is correspondingly arranged on the circuit board 110 with respect to the electrode assembly 130. The bottom plate 141 and the electrode assembly 130 are respectively located on opposite sides of the circuit board 110. The bottom plate 141 is made of a heat-conducting material. For example, materials with relatively high thermal conductivity such as electroless nickel-plated copper. The housing 142 is arranged on the side of the bottom plate 141 away from the circuit board 110. An inlet 1421 and an outlet 1422 communicating with the cavity 143 are provided on the housing 142. The inlet 1421 and the outlet 1422 are used to be respectively connected to a storage tank (not shown in the figure) through pipelines, and a coolant is circulated to the cavity 143 through a driving pump (not shown in the figure). The coolant can be water, liquid nitrogen, etc. Specifically, there are multiple cooling components 140 and they share a storage tank.

[0040] The bottom plate 141 with relatively high thermal conductivity is arranged corresponding to the electrode assembly 130. The heat of the electrode assembly 130 is conducted to the bottom plate 141, and the heat is continuously carried away by the circulated coolant, realizing continuous cooling and temperature reduction of the electrode assembly 130. Copper itself has excellent thermal conductivity, and its thermal conductivity is much higher than that of general metals. Through electroless nickel plating treatment, while maintaining the high thermal conductivity of copper, its surface hardness and corrosion resistance can be improved, ensuring that the bottom plate 141 can quickly and effectively conduct the heat generated by the electrode assembly 130 into the coolant.

[0041] In one embodiment, refer to Figure 1 and Figure 3 , a plurality of heat dissipation members 1411 are spacedly arranged on the side of the bottom plate 141 away from the circuit board 110. The heat dissipation members 1411 can be in the shape of a sheet, a column, a rod, etc. For example, when the heat dissipation members 1411 are in the shape of a sheet, a plurality of heat dissipation members 1411 are arranged in parallel; when the heat dissipation members 1411 are in the shape of a column or a rod, the heat dissipation members 1411 are distributed in an array of multiple rows or multiple columns. Preferably, the heat dissipation members 1411 are integrally formed with the bottom plate 141. By arranging the heat dissipation members 1411 on the bottom plate 141, the contact area between the bottom plate 141 and the coolant is increased, that is, the heat dissipation area is increased, so that the heat of the bottom plate 141 can be quickly transferred to the coolant, thereby improving the heat dissipation efficiency and ensuring that the heat of the motor assembly can be taken away more effectively and quickly.

[0042] In some specific embodiments, refer to Figure 1 and Figure 3, both the inlet 1421 and the outlet 1422 are located on the side of the housing 142 away from the bottom plate 141, or the inlet 1421 and the outlet 1422 are respectively located on opposite sides of the housing 142. The coolant in the pipeline enters the cavity 143 through the inlet 1421, passes through the bottom plate 141 and the heat sink 1411, takes away its heat, and is discharged from the outlet 1422, and then returns to the storage tank through the pipeline to realize the circulating refrigeration of the coolant.

[0043] In some embodiments, referring to Figure 3 , the bottom plate 141 and the housing 142 can be hermetically fixed by means such as welding, fasteners, adhesives or seals.

[0044] In one embodiment, referring to Figure 1 , the electrode mechanism further includes a refrigerating element 150 disposed between the circuit board 110 and the cooling assembly 140. The refrigerating element 150 is a thermoelectric cooler, which uses the thermoelectric effect of semiconductors to refrigerate. The thermoelectric cooler has a hot end and a cold end. The cold end of the thermoelectric cooler is disposed on the circuit board 110, the power supply circuit of the thermoelectric cooler is disposed on the circuit board 110 and is connected by welding, and the hot end of the thermoelectric cooler is fixedly connected to the bottom plate 141 of the cooling assembly 140 through heat-conducting paste. The thermal conductivity of the heat-conducting paste can be between 6-9 w / mk to enhance the heat conduction efficiency. The bottom plate 141 covers the hot end area of the thermoelectric cooler, and the electrode assembly 130 is located within the coverage of the thermoelectric cooler, so as to ensure that all the electrode assemblies 130 can be effectively cooled.

[0045] The cold end of the thermoelectric cooler faces the electrode assembly 130, the heat of the hot end of the thermoelectric cooler is taken away by the bottom plate 141, and the heat is continuously taken away by the circulating coolant. The heat of the electrode assembly 130 is controlled by the thermoelectric cooler, and the cold end of the thermoelectric cooler balances the heat of the electrode assembly 130, and the cooling assembly 140 cools the hot end of the thermoelectric cooler.

[0046] In some specific embodiments, referring to Figure 1 and Figure 2 , the refrigerating element 150 is fixed to the circuit board 110 by means such as snap fasteners 160, adhesives or fasteners. Specifically, the snap fastener 160 can be located inside the refrigerating element 150 and pass through the refrigerating element 150 or be located at the edge of the refrigerating element 150. The refrigerating element 150 is pressed and fixed to the circuit board 110 by the end 161 of the snap fastener 160, and the style of the snap fastener 160 is not limited.

[0047] In some embodiments, referring to Figure 4 and Figure 5 , the cooling assemblies 140 and the electrode assemblies 130 are arranged in one-to-one correspondence; or, referring to Figure 6 , one cooling assembly 140 corresponds to at least two electrode assemblies 130.

[0048] In some other embodiments, referring to Figure 5 and Figure 6 , at least two electrode assemblies 130 are provided on the same conductive line 120; alternatively, referring to Figure 4 , the electrode assemblies 130 are arranged in one-to-one correspondence with the conductive lines 120.

[0049] In one embodiment, referring to Figure 7 , the electrode mechanism further includes a control device 170, and the control device 170 includes a main control module 174 provided on the circuit board 110. The control device 170 further includes a temperature monitoring module 171 provided on the circuit board 110. The temperature monitoring module 171 is connected to the electrode assembly 130 and is used to detect the actual temperature of the electrode assembly 130. The main control module 174 is connected to the temperature monitoring module 171. The main control module 174 is used to judge whether the electrode assembly 130 exceeds a preset temperature range or has a tendency to exceed the preset temperature range according to the actual temperature data. If so, at least one of the refrigerating capacity of the refrigerating member 150, the output power of the electrode assembly 130, and the supply amount of the refrigerant of the cooling assembly 140 is controlled and adjusted; and / or, the control device 170 further includes an impedance monitoring module 172 provided on the circuit board 110. The impedance monitoring module 172 is connected to the electrode assembly 130 and is used to detect the actual impedance value between the electrode assembly 130 and the skin. The main control module 174 is connected to the impedance monitoring module 172 and is used to judge whether the actual impedance value exceeds the set impedance range according to the actual impedance value. If so, the main control module 174 controls the electrode assembly 130 to stop outputting energy.

[0050] The temperature monitoring module 171 (for example, a thermocouple) monitors the temperature of the electrode assembly 130 in real time. The main control module 174 is connected to the temperature monitoring module 171, the refrigerating member 150, the electrode assembly 130, and the cooling assembly 140. The main control module 174 has a specific algorithm program built in. The main control module 174 receives the actual temperature data from the temperature monitoring module 171 and makes a temperature comparison judgment and a temperature trend judgment. According to the temperature judgment result, the main control module 174 feedback-adjusts at least one of the refrigerating capacity of the refrigerating member 150, the output power of the electrode assembly 130, and the supply amount of the refrigerant of the cooling assembly 140. For example, when the temperature of the electrode assembly 130 is too high, the supply amount of the coolant is increased to quickly reduce the temperature; when the temperature is too low, the supply amount of the coolant is reduced, so as to effectively avoid scalding the skin due to overheating of the electrode assembly 130 or frostbiting the skin due to overcooling, ensure that the user's skin is within a safe temperature range, and improve the comfort of the user during use.

[0051] Good adhesion helps with the effective transfer of energy, thereby improving the skin treatment effect. Conversely, if the adhesion is poor, it may lead to uneven energy transfer, affecting the usage effect and even safety. The impedance monitoring module 172 detects the actual impedance value between the electrode assembly 130 and the skin in real time. The main control module 174 receives the actual impedance value from the impedance monitoring module 172 and makes an impedance comparison judgment. If it detects that the impedance value exceeds the set impedance range, the main control module 174 controls the electrode assembly 130 to stop outputting energy to ensure the safety of user use. Further, the main control module 174 is also connected to an alarm. When it detects that the impedance value exceeds the set impedance range, the main control module 174 controls the alarm to issue a safety alarm, such as sound and / or light alarm information, to remind the user to adjust the adhesion between the electrode assembly 130 and the skin.

[0052] Further, the electrode mechanism further includes: an electromagnetic shielding module 173, which is disposed on the circuit board 110 and is used to shield electromagnetic interference. The electromagnetic shielding module 173 can effectively block or weaken the interference of the external electromagnetic field on the circuit board 110 and the electronic components thereon, which ensures that the electrode mechanism can still work stably and reliably in a complex electromagnetic environment (such as in a dense area of electronic devices or near a high electromagnetic radiation source), improving the anti-interference ability of the electrode mechanism. In addition to preventing external interference, the electromagnetic shielding module 173 can also prevent the electromagnetic radiation generated by the internal electronic components of the circuit board 110 from leaking outwards, protecting the user from potential health risks and preventing interference to other surrounding electronic devices.

[0053] In one embodiment, the circuit board 110 is a flexible circuit board, a rigid circuit board or a rigid-flexible combined circuit board; and / or, the circuit board 110 includes a polyimide film, and the polyimide film contains alumina, which can increase its thermal conductivity by 5 to 10 times, helping to quickly conduct the heat of the electrode assembly 130 to the refrigerating member 150 and improving the efficiency of cooling the electrode assembly 130.

[0054] Adopting a flexible circuit board or a rigid-flexible combined circuit board with flexibility and bendability enables it to closely and smoothly adhere to the shell of a flexible electronic device (such as an electronic facial mask, a treatment eye mask, etc.), without affecting the flexibility of the flexible electronic device, thereby ensuring that when in use, the electrode assembly 130 can fit well with the user's skin.

[0055] In yet another embodiment, the electrode assembly 130 is a rigid electrode or a flexible electrode. Due to its high hardness and strength, the rigid electrode is not easily deformed or damaged. The rigid electrode usually has excellent electrical conductivity, reducing energy loss and achieving efficient energy transmission. The flexible electrode can closely adhere to the skin surface, reducing the air gap, which helps to reduce the loss of energy during transmission and improve the energy transmission efficiency.

[0056] The present utility model also provides an electrode device, comprising: an electrode mechanism as in any of the above embodiments and a packaging layer covering and disposed outside the circuit board 110, with a part of the electrode assembly 130 exposed outside the packaging layer to contact the skin. The electrode device is fixed to the skin by a hard fixing method (e.g., adhesive, strap, etc.) and / or a soft fixing method (e.g., by applying a conductive and viscous material such as conductive gel), and then, in cooperation with a water tank and a main unit, it can be used.

[0057] Specifically, the packaging layer is non-woven fabric. Using non-woven fabric as the packaging layer not only provides good air permeability and moisture absorption, but also reduces the discomfort caused by long-term use, such as stuffiness and dampness. The soft touch of the non-woven fabric also improves the user experience.

[0058] The present utility model also provides a skin treatment instrument, comprising: a housing and an electrode mechanism as in any of the above embodiments, with the electrode mechanism disposed on the housing. When the circuit board 110 is a flexible circuit board or a rigid-flexible circuit board and the electrode assembly 130 is a flexible electrode, the skin treatment instrument can be an electronic facial mask, a treatment mask, a treatment helmet (flexible), a treatment eye mask or an abdominal wrap, etc. When the circuit board 110 is a rigid circuit board and the electrode assembly 130 is a rigid electrode, the skin treatment instrument can be a treatment helmet (rigid) or a handheld skin treatment instrument.

[0059] The technical effects of the present utility model will be explained in detail below.

[0060] 1. The electrode assembly 130 is cooled by the cooling component 140, so that the electrode assembly 130 can output higher energy to deepen the skin treatment depth and range, enhance the treatment effect, and at the same time avoid damaging the user's skin due to the over-high temperature of the electrode assembly 130.

[0061] 2. The temperature of the electrode assembly 130 can be quickly reduced by the refrigerating member 150, improving the comfort during the treatment process.

[0062] 3. The coolant circulates to carry away the heat of the electrode assembly 130, not only improving the cooling efficiency, but also ensuring the stability and continuity of the cooling process.

[0065] 6. The impedance monitoring module 172 can detect the impedance value between the electrode assembly 130 and the skin, thereby evaluating the fitting condition of the electrode assembly 130 with the skin and ensuring the safety and treatment effect of the treatment.
