Description

Technical Field

[0001] This application relates to the field of beauty device technology, and in particular to an electrode pad and energy delivery device. Background Technology

[0002] With the continuous development of the medical aesthetics technology field, more and more beauty devices or equipment are rapidly developing towards portability and miniaturization. Currently, portable small electronic masks have appeared on the market, which can temporarily provide electronic beauty treatments to users' facial skin. However, these electronic masks lack a temperature feedback mechanism; they can only release energy to the user's skin when connected to a power source to perform the beauty treatment. If too much energy is released to the user's facial skin in a short period, the skin temperature will rise abnormally, potentially causing burns. If too little energy is released, the skin temperature will be too low, resulting in poor treatment effects. It is also difficult to accurately detect the skin temperature and confirm whether the beauty effect is appropriate. Utility Model Content

[0033] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0034] In the description of this application, it should also be noted that, unless otherwise explicitly specified and limited, the term "mechanical connection" should be interpreted broadly, distinguishing it from electrical connections that are fixed, detachable, or integrally formed, such as various welded, snap-fit, and threaded connections. It can be a direct connection or an indirect connection through an intermediate medium, and can represent the internal connection of two components. Those skilled in the art can understand the specific meaning of the above term in this application based on the specific circumstances.

[0035] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0036] This application presents a first embodiment of an energy transmission device; please refer to... Figure 1 The electrode pad includes:

[0037] Flexible circuit board 10;

[0038] Multiple temperature sensors 20 are mechanically connected to the flexible circuit board 10;

[0039] Each of the temperature sensors 20 has a first terminal and a second terminal;

[0040] Each of the first terminals is electrically connected to the first trace of the flexible circuit board 10, and each of the second terminals is electrically connected to a plurality of second traces of the flexible circuit board 10 in a one-to-one correspondence. The first trace and the plurality of second traces are used to supply preset DC power to the plurality of temperature sensors 20.

[0041] It should be understood that, in this embodiment, the temperature sensor 20 can be an NTC resistor. The real-time impedance of an NTC resistor can decrease as the ambient temperature rises or increase as the temperature falls. Therefore, by providing a preset DC current to the temperature sensor 20 and acquiring the corresponding electrical parameters, the real-time impedance of the temperature sensor 20 can be obtained, and then the real-time temperature of the corresponding location area can be obtained based on the current real-time impedance.

[0042] It should be noted that, in this embodiment, multiple temperature sensors 20 can be mechanically connected to various areas on the flexible circuit board 10, and the first terminals of each temperature sensor 20 are connected together through a first trace. The end of the first trace can be connected to a grounding port provided on the flexible circuit board 10. Simultaneously, the second terminals of each temperature sensor 20 can be connected one-to-one to multiple DC power supply ports provided on the flexible circuit board 10 through their respective second traces. Thus, each DC power supply port can be connected to the second terminal of its corresponding temperature sensor 20 through its corresponding second trace, and the grounding port can be connected to the first terminal of each temperature sensor 20 through its first trace. When the electrode pad is electrically connected to an external device or equipment through the DC power supply ports and the grounding port, each temperature sensor 20 can simultaneously form multiple parallel connection loops with the external device or equipment through its first trace and its corresponding second trace. A preset DC power transmitted by the external device or equipment can be provided to each corresponding temperature sensor 20 according to each connection loop, and the external device or equipment can obtain the real-time temperatures collected by each temperature sensor 20 by collecting the electrical parameters in each connection loop, thereby facilitating the judgment of the cosmetic effect of the current electrode pad.

[0043] Furthermore, in this embodiment, the electrode pad further includes: an encryption chip 30;

[0044] The encryption chip 30 is mechanically connected to the flexible circuit board 10;

[0045] The encryption chip 30 has an encryption port, which is electrically connected to the third trace of the flexible circuit board 10. The third trace is used to transmit encrypted information stored inside the encryption chip 30.

[0046] It should be noted that, in this embodiment, an encryption chip 30 is also mechanically connected to the flexible circuit board 10. The encryption chip 30 stores encrypted information including the current working parameters of the electrode pad and production identification.

[0047] In a specific implementation, the encryption port of the encryption chip 30 can be electrically connected to the third trace on the flexible circuit board 10, and the third trace is connected to the encryption output port provided on the flexible circuit board 10. When the encryption output port is connected to an external device or external equipment, the encryption chip 30 can transmit the internally stored encryption information to the external device or external equipment through the third trace on the flexible circuit board 10, so that the external device or external equipment can obtain the initial operating parameters required by the current electrode pad (the operating parameters of electrode pads working in different skin areas are different). Here, the operating parameters can be understood as the electrical parameters sent to the electrode pad by the external device or external equipment, including the preset DC electrical parameters mentioned above.

[0048] In addition, external devices or equipment can identify the production markings of the current electrode pad to determine whether the current electrode pad is a genuine product or an expired product, so as to better provide after-sales service.

[0049] Furthermore, in this embodiment, the flexible circuit board 10 includes: a plurality of electrode sheets 40;

[0050] Each of the electrode plates 40 has a radio frequency port, and each radio frequency port is electrically connected to a plurality of fourth traces of the flexible circuit board 10 in a one-to-one correspondence. Each of the fourth traces is used to deliver a preset pulse to its corresponding electrode plate 40.

[0051] Each of the electrode sheets 40 is exposed on one side of the flexible circuit board 10, and each of the temperature sensors 20 is disposed on the other side of the flexible circuit board 10, with each of the temperature sensors 20 mapped onto each of the electrode sheets 40.

[0052] It should be understood that, in this embodiment, the flexible circuit board 10 also has a plurality of electrode sheets 40, each electrode sheet 40 being disposed on one side of the electrode area of ​​the flexible circuit board 10 for exposure.

[0053] It should be noted that, in this embodiment, each electrode pad 40 has a radio frequency (RF) port on its unexposed side. Each RF port is electrically connected to a corresponding fourth trace in the flexible circuit board 10, and the end of each fourth trace is connected to an RF input port on the flexible circuit board 10. When the RF input port is connected to an external device or equipment, each electrode pad 40 can obtain a preset pulse current transmitted by the external device or equipment through the corresponding fourth trace, and use the preset pulse current to perform cosmetic treatment on the user's skin.

[0054] It is worth noting that, in this embodiment, as one scenario, the preset pulse current can be a low-frequency pulse current with a frequency below 100 Hz, which can be either alternating current or direct current. When the electrode pad 40 receives the low-frequency pulse current, it can promote the production of collagen and elastin in the user's skin through electrical stimulation, thereby achieving a cosmetic effect on the user's skin. Alternatively, the preset pulse current can be a high-frequency current with a frequency above 10000 Hz. When the electrode pad 40 receives the high-frequency current, it can generate high-frequency electromagnetic waves (radio frequency energy), which can promote the regeneration of collagen and tissue metabolism in the dermis of the user's skin through radio frequency energy, thereby achieving a cosmetic effect on the user's skin.

[0055] It is readily understood that, in this embodiment, each temperature sensor 20 can be disposed on the side of the electrode area on the flexible circuit board 10 where the electrode plates 40 are not exposed, and the specific position of each temperature sensor 20 can be correspondingly set according to the positional distribution of the electrode plates 40, so that each temperature sensor 20 is mapped onto each electrode plate 40. Mapping can be performed one-to-one, or multiple temperature sensors 20 can be mapped onto the same electrode plate 40. As a preferred example, the mapping position of each temperature sensor 20 can be set in a preset central area on the corresponding electrode plate 40 to improve the accuracy of temperature acquisition.

[0056] Furthermore, in this embodiment, each of the electrode sheets 40 is symmetrically distributed around a preset axis, and a gap coated with dielectric material is provided between each adjacent electrode sheet 40.

[0057] It is easy to understand that in this embodiment, each electrode sheet 40 can be symmetrically distributed along a preset axis on the electrode area, and a certain gap can be provided between adjacent electrode sheets 40 so that each electrode sheet 40 can better fit the uneven area on the user's skin.

[0058] It is worth noting that, in this embodiment, the gaps between adjacent electrode sheets 40 can be coated with a dielectric material to better form the required electric field, thereby improving the effect of skin electrical stimulation or radiofrequency treatment on the user.

[0059] Furthermore, in this embodiment, each of the electrode sheets 40 is coated with an inert metal layer, the thickness of which is 0.001-0.05 μm.

[0060] It is easy to understand that, in this embodiment, the surface of each electrode sheet 40 may also be plated with an inert metal layer, such as a gold layer. The thickness of the inert metal layer may be limited to within 0.001-0.05 μm. The conductivity and mechanical flexibility of each electrode sheet 40 can be adjusted by controlling the thickness of the inert metal layer, so as to improve the cosmetic treatment effect and the user's tactile sensory experience.

[0061] This application provides an electrode pad, comprising: a flexible circuit board; multiple temperature sensors mechanically connected to the flexible circuit board; each temperature sensor having a first terminal and a second terminal; each first terminal being electrically connected to a first trace on the flexible circuit board, and each second terminal being electrically connected to a plurality of second traces on the flexible circuit board respectively, wherein the first trace and the plurality of second traces are used to supply a preset DC current to the plurality of temperature sensors. By providing a preset DC current to the plurality of temperature sensors disposed on the flexible circuit board through the first trace and the plurality of second traces within the flexible circuit board, each temperature sensor can feed back the real-time temperature at each position on the electrode pad through electrical parameters in multiple parallel current paths, thereby improving temperature acquisition accuracy and enabling more precise confirmation of cosmetic effects.

[0062] Based on the first embodiment of the electrode pad of this application, in the second embodiment of the electrode pad of this application, the contents that are the same as or similar to those in Embodiment 1 above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 The electrode pad further includes: conductive gel 50;

[0063] The conductive gel 50 is attached to the surface of each of the electrode sheets 40. The impedance of the conductive gel 50 does not exceed 1KΩ, and the pH value of the conductive gel 50 is in the range of 3.5-7.

[0064] It should be noted that, in this embodiment, a conductive gel 50 with an impedance of less than 1KΩ can also be disposed on the surface of each electrode pad 40 to facilitate better adhesion to the user's skin and to protect each electrode pad 40 from damage. Setting its impedance to a range similar to that of the human epidermis allows for better transmission of electrical stimulation or radiofrequency energy to the user's skin. The conductive gel 50 can be a human-dermal-like gel with a pH value between 3.5 and 7, making the user more comfortable when applying the electrode pads 40 without damaging the skin.

[0065] Furthermore, in this embodiment, the electrode pad further includes: release paper 60;

[0066] The release paper 60 covers the surface of the conductive gel 50 and is used to protect the conductive gel 50.

[0067] It should be noted that in this embodiment, a release paper 60 can also be covered on the surface of the conductive gel 50. The release paper 60 is mainly used to protect the conductive gel 50 and the internal electrode pad 40. When the electrode pad needs to be used, the user can find the handle of the release paper 60 by following the tear-off markings on the release paper 60, so as to facilitate the user to peel off the release paper 60 and use the electrode pad for cosmetic treatment.

[0068] Furthermore, in this embodiment, the electrode pad further includes: medical foam 70;

[0069] The medical foam 70 is attached to the non-electrode area of ​​the flexible circuit board 10.

[0070] It is easy to understand that, in this embodiment, a layer of medical foam 70 can also be attached to the non-electrode area of ​​the flexible circuit board 10, so that the user's tactile experience is more comfortable when the flexible circuit board 10 is attached to the user's skin.

[0071] It is worth noting that, in this embodiment, the medical foam can also be attached to the surface of the electrode area connected to each temperature sensor 20.

[0072] Furthermore, in this embodiment, the shape of the electrode area of ​​the flexible circuit board 10 and the shape of each electrode sheet 40 distributed on the electrode area can be designed according to the specific contours of human skin. This can be combined with... Figures 3 to 6 To understand, Figure 3 The shapes of the electrode areas and the electrode pads 40 shown are suitable for facial skin. Figure 4 The shapes of the electrode areas and the electrode pads 40 shown are suitable for forehead skin. Figure 5 The shapes of the electrode areas and the electrode pads 40 shown are suitable for the skin of the mandible. Figure 6 The shapes of the electrode areas and the electrode pads 40 shown are suitable for the skin around the eyes.

[0073] As is easily understood, electrical stimulation for cosmetic purposes is primarily suitable for areas of the face with more muscles. It involves electrically stimulating muscles such as the zygomaticus minor, zygomaticus major, orbicularis oculi, frontalis, and risorius to achieve effects such as thickening muscle fibers, strengthening muscles, and improving facial expression. For example... Figure 6 Facial skin areas such as the skin around the eyes and mouth are not suitable for cosmetic treatments involving electrical stimulation. Therefore, cosmetic treatments that transmit radiofrequency energy can be used to treat the skin in these areas to improve the overall comfort of the treatment.

[0074] It is worth noting that for certain skin areas, some of the electrode pads 40 in the electrode area can work by electrical stimulation, while others can work by transmitting radiofrequency energy, thereby further improving the treatment effect and reducing the treatment time.

[0075] This application also provides an energy transmission device, see reference. Figure 7 The energy transmission device includes: a host computer 200, which includes a host computer 202 and a DC power supply 201; and an electrode pad 100 as described above.

[0076] The electrode pad 100 is detachably connected to the host 200. The DC power supply 201 is used to provide preset DC power to multiple temperature sensors 20 through a first trace and multiple second traces when the electrode pad 100 is connected to the host 200. The host computer 202 is used to collect multiple sets of voltage differences between the first trace and each of the second traces when the electrode pad 100 is connected to the host 200, and to obtain the real-time temperature of the electrode pad 100 based on each set of voltage differences.

[0077] It should be understood that, Figure 7 The diagram below is a simplified structural diagram of one example of this embodiment. It only describes the structural connection diagram corresponding to the case where a temperature sensor 20 outputs a preset DC current, an electrode plate 40 outputs a preset pulse current, and the encrypted information transmitted by the encryption chip 30 is obtained. It should not be considered as limiting the number of temperature sensors 20, electrode plates 40, and the number of corresponding connection lines.

[0078] It should be noted that in this embodiment, the electrode pad 100 can be assembled with the host 200 through a number of ports provided on the flexible circuit board 10, and the host 200 can be understood as the external device or external equipment mentioned above.

[0079] It is easy to understand that, in this embodiment, if the electrode pad 100 is connected to the host 200, the negative terminal of the DC power supply 201 inside the host 200 can be connected to the first trace of the electrode pad 100, and the multiple positive terminals of the DC power supply 201 can be connected to the multiple second traces of the electrode pad 100 one by one, thereby supplying a constant current of preset DC power to the multiple temperature sensors 20 of the electrode pad 100 respectively. Simultaneously, the host computer 202 can collect the electrical parameters of the electrical signals transmitted between each connected second trace and the first trace, such as the voltage difference between a certain second trace and the first trace. The host computer 202 can determine the real-time temperature of the corresponding position of the electrode pad 100 collected by the current temperature sensor 20 based on the collected electrical parameters.

[0080] As an example, temperature sensor 20 is an NTC resistor, and DC power supply 201 can output a constant current preset DC power to the corresponding temperature sensor 20. At this time, when the host 200 is connected to the electrode pad 100, the impedance of the current temperature sensor 20 can be determined by the voltage difference between the corresponding second trace and the first trace collected by the host computer 202 and the current value of the preset DC power. Then, combined with the temperature / impedance characteristics of the NTC resistor, the real-time temperature of the corresponding position of the electrode pad 100 collected by the temperature sensor 20 can be obtained.

[0081] It is worth noting that, in this embodiment, there may be an electrical connection between the DC power supply 201 and the host computer 202. The host computer 202 may output a corresponding current control signal to control whether the DC power supply 201 outputs a preset DC power and to adjust the electrical parameters of the preset DC power.

[0082] Furthermore, in this embodiment, the host computer 202 is also used to send preset pulses to the multiple electrode pieces 40 of the electrode pad 100 through multiple fourth traces when the electrode pad 100 is connected to the host computer 200.

[0083] It should be noted that in this embodiment, the host computer 202 can also generate and send pulse signals. In specific implementation, when the electrode pad 100 is connected to the host computer 200, the host computer 202 can electrically connect to multiple electrode pads 40 on the electrode pad 100 through multiple fourth traces on the electrode pad 100. The host computer 202 can send the generated pulse signals to their respective corresponding electrode pads 40 through each fourth trace, that is, send preset pulse electricity to each electrode pad 40. This allows each electrode pad 40 to perform electrical stimulation or send radio frequency energy to the user's skin based on the preset pulse electricity it receives, thereby achieving electrode-based cosmetic treatment for the user's skin.

[0084] Furthermore, in this embodiment, the host computer 202 is also used to adjust the electrical parameters of the preset pulse current based on the real-time temperature of the electrode pad 100.

[0085] It should be noted that in this embodiment, the host computer 202 can also determine the cosmetic effect of the current electrode pad 100 based on the real-time temperature collected by each temperature sensor 20 on the electrode pad 100. If the real-time temperature collected by one or more temperature sensors 20 is detected to be too high or too low, it can be determined that the operating parameters of the current electrode pad 100 are abnormal, and the preset pulse current output to each electrode plate 40 needs to be appropriately adjusted. When a real-time temperature is detected to be too high, any one or more of the electrical parameters of the preset pulse current, such as amplitude, frequency, and duty cycle, can be reduced to prevent burns to the user's skin; when a real-time temperature is detected to be too low, any one or more of the electrical parameters of the preset pulse current, such as amplitude, frequency, and duty cycle, can be increased to improve the cosmetic effect.

[0086] Furthermore, in this embodiment, the host computer 202 is also used to receive encrypted information sent by the encryption chip 30 of the electrode pad 100 through a third trace when the electrode pad 100 is connected to the host computer 200, and to set the initial electrical parameters of the preset pulse current based on the encrypted information.

[0087] It should be noted that in this embodiment, when the host computer 200 is connected to the electrode pad 100, the host computer 202 can also be electrically connected to the encryption chip 30 of the electrode pad 100 through the third trace on the flexible circuit board 10. At this time, the host computer 202 can receive the encrypted information sent by the encryption chip 30, thereby identifying the current operating parameters and production identification of the electrode pad 100. The operating parameters include the preset DC power parameters output to the electrode pad 100 and the initial electrical parameters of the preset pulse power, as mentioned above, so as to provide different electrical parameters for electrode pads designed for different skin areas, thereby providing the best cosmetic effect for each area of ​​the user's skin. The production identification can be understood as being used to distinguish whether the current electrode pad 100 is a genuine product or a used product, preventing counterfeit or inferior products from being assembled and used with the host computer 200, and facilitating after-sales service.

[0088] It is worth noting that in this embodiment, after the host computer 202 obtains the encrypted information, the time of obtaining the encrypted information can be set as the time when the electrode pad 100 starts to be used, and a timer will be started. When the accumulated time reaches the preset beauty time, it will be determined that the electrode pad 100 is no longer usable, and the transmission of preset electrical pulses to the electrode pad 100 will stop, so as to prevent damage to the user's skin from prolonged excessive beauty treatment.

[0089] Since the energy delivery device provided in this application embodiment uses the electrode pad described above, it can also solve the technical problem of how to more accurately detect temperature to confirm the beauty effect when performing electrode beauty treatments on users. Compared with the prior art, the other beneficial effects of the energy delivery device provided in this application embodiment are the same as the beneficial effects of the electrode pad provided in the above embodiments, and will not be repeated here.

[0090] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent scope of this application.
