[0062] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0063] Embodiment 1

[0064] Please also read Figure 1-3 The present invention discloses an electrode assembly 10, which can be applied to a massage device to massage a part of a human body to be massaged to achieve a soothing effect. The electrode assembly 10 includes a carrier 160, a non-metallic electrode sheet 180 and a metal foil 170. The carrier 160 can be used to be detachably supported on the massage device on the side to be massaged facing the human body. The non-metallic electrode sheet 180 is carried on the carrier 160 for contacting with human skin; the metal foil 170 is at least partially coated on the first surface 161 and the second surface 162 opposite to the carrier 160, and the part of the metal foil 170 coated on the first surface 161 is attached to the non-metallic electrode sheet 180.

[0065] It is understandable that the massage device can be a massage device used in conjunction with the electrode assembly, such as a wearable massage device and / or a massage head, etc. The carrier 160 is detachably connected to the massage device in a manner of being supported on the massage device, which means that the carrier 160 is directly arranged on the massage device, so that the massage device can be used as a support end or a wearable end, so that when the user wears or holds the massage device on the part to be massaged, the non-metallic electrode sheet 180 of the electrode assembly 10 can contact the part to be massaged by the user to achieve massage.

[0066] The first surface 161 of the carrier 160 may be an upward facing surface. Figure 1 As shown in the upward direction in FIG. 1 , the second surface 162 of the carrier 160 is a surface opposite to the first surface 161 , that is, the second surface 162 is a downward surface.

[0067] By coating the metal foil 170 on the first surface 161 and the second surface 162 of the carrier 160, when the electrode assembly 10 is mounted on a massage head provided with a heating component / heating sheet, the metal foil 170 can transfer heat from the second surface 162 of the carrier 160 to the first surface 161, and then transfer it to the non-metallic electrode sheet 180, thereby achieving the effect of heating the non-metallic electrode sheet 180. Since the metal foil 170 is in the form of a thin sheet, it has a fast heat conduction speed and low heat loss, and can transfer as much heat as possible to the non-metallic electrode sheet 180, thereby improving the heat conduction efficiency of the electrode assembly 10. When the non-metallic electrode sheet 180 is used, it can also be effectively heated, so that the electrode assembly 10 has a hot compress effect.

[0068] Optionally, the non-metallic electrode sheet 180 is a conductive gel sheet or a silicone conductive sheet. Exemplarily, the non-metallic electrode sheet 180 is a conductive gel sheet and conducts electricity through the metal foil 170. Since the surface of human skin is covered with a layer of scaly stratum corneum, which is a poor conductor of electricity, when the metal electrode sheet is directly attached to the surface of the stratum corneum, it is not easy for the current to pass through the metal electrode sheet and conduct with the human skin, and energy concentration is likely to occur locally, causing stinging. Therefore, the present invention adopts the design that the non-metallic electrode sheet 180 is a conductive gel sheet, and the conductive gel sheet can be used to fill the gap in the scaly stratum corneum, so that the conductive gel sheet can directly contact the dermis under the human stratum corneum, and then the conductive gel sheet and the part attached to the surface of the human skin can be fully electrically connected with the dermis, thereby increasing the area of ​​electrical conduction, reducing local energy concentration, avoiding stinging during use, and improving the user experience.

[0069] On the other hand, the conductive gel sheet can generate water vapor so that the non-metallic electrode sheet 180 forms a good fit with the skin. The carrier 160 is a plastic sheet, and the projection of the non-metallic electrode sheet 180 on the carrier 160 is covered by the carrier 160. The plastic sheet has good water-proof and air-proof properties, which can effectively prevent water vapor from penetrating into the massage head, avoiding corrosion of the internal components or short circuit of the internal circuit. At the same time, the carrier 160 is a plastic sheet with good elasticity and plasticity, which can adapt to the deformation of the mounting surface of the base to achieve good fitting installation. It can also have a relatively flat shape during manufacturing, transportation, and storage, which is convenient for manufacturing, transportation, and storage.

[0070] Optionally, the metal foil 170 is a copper foil or an aluminum foil, so as to have excellent electrical and thermal conductivity. Exemplarily, the metal foil 170 is a copper foil, which has excellent thermal conductivity and certain structural strength, and can effectively support the non-metallic electrode sheet 180 .

[0071] Furthermore, an optional way to coat the metal foil 170 on the first surface 161 and the second surface 162 of the carrier 160 is to directly coat the first surface 161 of the carrier 160 with a layer of metal foil 170 and simultaneously coat the second surface 162 of the carrier 160 with a layer of metal foil 170 .

[0072] Another optional way for the metal foil 170 to be coated on the first surface 161 and the second surface 162 of the carrier 160 is: the metal foil 170 may include an upper coating surface 172 and two side wings 173 arranged up and down, wherein the two side wings 173 extend outward from two sides 174 of the upper coating surface 172 and bend toward the second surface 162 of the carrier 160 to fit the second surface 162 of the carrier 160. In other words, in this way, when the metal foil 170 is disposed on the carrier 160, the metal foil 170 can be sleeved on the carrier 160 through the hollow space formed between the upper coating surface 172 and the two side wings 173, so that the carrier 160 is located in the hollow space of the metal foil 170, and the connection between the metal foil 170 and the carrier 160 can be completed. Optionally, if the metal foil 170 and the carrier 160 are to be further fixed, adhesive may be applied to the first surface 161 and the second surface 162 of the carrier 160 so that the first surface 161 and the second surface 162 of the carrier 160 are bonded to the upper covering surface 172 and the two side wings 173 respectively.

[0073] The upper covering surface 172 is oriented in the same direction as the first surface 161 of the carrier 160 , that is, in an upward direction, and the two side wings 173 are oriented in the same direction as the second surface 162 , that is, in a downward direction.

[0074] Furthermore, there is a distance between two opposite edges of the two side wings 173 , and light-transmitting holes 171 are provided at positions of the upper covering surface 172 corresponding to the distance to facilitate light transmission.

[0075] With the above design, when the electrode assembly 10 is applied to a massage head equipped with a light-emitting component or a far-infrared emitter, the distance and the light-transmitting hole 171 can be used to allow the light of the light-emitting component or the far-infrared rays to pass through the distance and the light-transmitting hole 171, thereby expanding the phototherapy and far-infrared functions of the electrode assembly 10.

[0076] Optionally, since the contact surface of the human neck is approximately a convex arc surface, in order to effectively adapt to the shape of the human neck and ensure that the non-metallic electrode sheet 180 can fit the neck, the carrier 160 is a concave arc shape, and the metal foil 170 and the non-metallic electrode sheet 180 are both flexible and deformable sheets. When the metal foil 170 and the non-metallic electrode sheet 180 are installed on the carrier 160, they can deform into a concave arc shape following the shape of the carrier 160, thereby effectively fitting the human neck.

[0077] Furthermore, the carrier 160 is a PVC sheet, PC or PP sheet with a light-transmitting matte surface, with a thickness of 0.1mm-0.5mm. The carrier 160 has a certain bearing capacity by using PVC, PC or PP sheets, and can effectively provide support for the metal foil 170 to shape the metal foil 170. The light-transmitting matte design can produce a uniform light effect on the light passing through the surface of the carrier 160.

[0078] The electrode assembly 10 disclosed in this embodiment 1 can fit the human neck more effectively through the concave arc design, and the non-metallic electrode sheet 180 adopts a conductive gel sheet or a silicone sheet, which can effectively avoid tingling when the user uses it; by adopting the metal foil 170 to conduct electricity and heat to the non-metallic electrode sheet 180, the metal foil 170 has a fast heat conduction speed and high safety, thereby improving the thermal conduction efficiency of the non-metallic electrode sheet 180 and enhancing the user experience.

[0079] Embodiment 2

[0080] Please also read Figure 4 and Figure 5 The present invention discloses a massage head 100, comprising: a base, a heating sheet 150, a metal foil 170, a non-metallic electrode sheet 180, a first conductive member 210 and a second conductive member 220. The non-metallic electrode sheet 180 is used to contact with human skin, and the upper surface of the non-metallic electrode sheet 180 is a massage surface for contacting the user's massaged part. The non-metallic electrode sheet 180, the metal foil 170 and the heating sheet 150 are sequentially arranged from top to bottom. The heating sheet 150 is arranged on a side of the base where the electrode assembly 10 is arranged, and the metal foil 170 is arranged toward the heating sheet 150. The metal foil 170 is arranged under the non-metallic electrode sheet 180 and is electrically connected to the non-metallic electrode sheet 180. The metal foil 170 abuts against the heating sheet 150 to conduct heat to the non-metallic electrode sheet 180.

[0081] The metal foil 170 is electrically connected to the first conductive member 210 and insulated from the heating sheet 150. The heating sheet 150 is electrically connected to the second conductive member 220 and insulated from the metal foil 170. The metal foil 170 is electrically connected to the non-metallic electrode sheet 180, so that a pulse current is applied to the user's massaged part through the non-metallic electrode sheet 180 to accelerate the blood circulation of the neck muscles. The heat generated by the heating sheet 150 being electrically connected to the second conductive member 220 is transferred to the non-metallic electrode sheet 180 through the metal foil 170. The metal foil 170 is soft and has high safety and good heat transfer properties, so that the heat is well transferred to the non-metallic electrode sheet 180, thereby improving the heat transfer efficiency.

[0082] Among them, the first conductive member 210 is the first power source connected to the metal foil 170, and the second conductive member 220 is the second power source connected to the heating sheet 150, and the first power source and the second power source are different power sources. Considering that the non-metallic electrode sheet 180 is mainly used to contact with the human neck to achieve pulse massage, and the heating sheet 150 is to achieve heat by energizing and transfer heat to the non-metallic electrode sheet 180, therefore, the first power source is an EMS (microcurrent) power source, and the second power source is the power source connected to the massage head 100 or the power source connected to the massage head 100.

[0083] It should be noted that the power source mentioned here does not refer to a battery, but a current source that can power the electrode assembly 10 and the heating plate 150. The power source can be obtained directly from the battery or from a control board, circuit board, etc. that is electrically connected to the battery.

[0084] In this embodiment, the massage head 100 further includes a carrier 160 , wherein the non-metallic electrode sheet 180 is carried on the carrier 160 , the metal foil 170 is coated on the first surface 161 and the second surface 162 of the carrier 160 , and the upper surface of the metal foil 170 is attached to the lower surface of the non-metallic electrode sheet 180 .

[0085] The first surface 161 of the carrier 160 is an upward surface. Figure 3 As shown in the upward direction in FIG. 1 , the second surface 162 of the carrier 160 is a surface opposite to the first surface 161 .

[0086] By coating the metal foil 170 on the first surface 161 and the second surface 162 of the carrier 160, the metal foil 170 can transfer the heat generated by the heating sheet 150 from the second surface 162 of the carrier 160 to the first surface 161, and then transfer it to the non-metallic electrode sheet 180, so as to achieve the effect of heating the non-metallic electrode sheet 180. Since the metal foil 170 is in the form of a thin sheet, it has a fast heat conduction speed and low heat loss, and can conduct as much heat as possible to the non-metallic electrode sheet 180, thereby improving the heat conduction efficiency of the electrode assembly 10. When the non-metallic electrode sheet 180 is used, it can also be effectively heated, so that the electrode assembly 10 has a hot compress effect.

[0087] Furthermore, an optional way to coat the metal foil 170 on the first surface 161 and the second surface 162 of the carrier 160 is to directly coat the first surface 161 of the carrier 160 with a layer of metal foil 170 and simultaneously coat the second surface 162 of the carrier 160 with a layer of metal foil 170 .

[0088] Another optional way for the metal foil 170 to be coated on the first surface 161 and the second surface 162 of the carrier 160 is: the metal foil 170 may include an upper coating surface 172 and two side wings 173 arranged up and down, wherein the two side wings 173 extend outward from two sides 174 of the upper coating surface 172 and bend toward the second surface 162 of the carrier 160 to fit the second surface 162 of the carrier 160. In other words, in this way, when the metal foil 170 is disposed on the carrier 160, the metal foil 170 can be sleeved on the carrier 160 through the hollow space formed between the upper coating surface 172 and the two side wings 173, so that the carrier 160 is located in the hollow space of the metal foil 170, and the connection between the metal foil 170 and the carrier 160 can be completed. Optionally, if the metal foil 170 and the carrier 160 are to be further fixed, adhesive may be applied to the first surface 161 and the second surface 162 of the carrier 160 so that the first surface 161 and the second surface 162 of the carrier 160 are bonded to the upper covering surface 172 and the two side wings 173 respectively.

[0089] Furthermore, there is a distance between two opposite edges of the two side wings 173 , and light-transmitting holes 171 are provided at positions of the upper covering surface 172 corresponding to the distance to facilitate light transmission.

[0090] Further, the carrier 160 is a plastic sheet, for example, a PVC sheet, PC or PP sheet with a light-transmitting matte surface, with a thickness of 0.1 mm-0.5 mm. Optionally, the thickness of the carrier 160 is 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm. By using PVC, PC or PP sheets, the carrier 160 has a certain bearing capacity, which can effectively provide support for the metal foil 170 and shape the metal foil 170. The light-transmitting matte design can produce a uniform light effect on the light passing through the surface of the carrier 160.

[0091] The carrier 160 adopts the above thickness because when the carrier 160, the metal foil 170, and the non-metallic electrode sheet 180 are bonded together to form a sheet structure, it has good flexibility and deformability. When the top of the base 120 is set in an arc shape to adapt to the shape of the human neck, the sheet structure formed by the carrier 160, the metal foil 170, and the non-metallic electrode sheet 180 can adapt to the arc shape and deform, so as to fit the top of the base 120, and then fit the human neck skin during massage. When the sheet structure formed by the carrier 160, the metal foil 170, and the non-metallic electrode sheet 180 is detached from the top of the base, the sheet structure can be deformed from the arc shape to a flat plate, so as to facilitate the storage and cleaning of the sheet structure.

[0092] In other words, the sheet structure can be deformed and switched between a top arc shape and a flat plate shape adapted to different bases according to different usage scenarios, and has a wider applicability.

[0093] Optionally, the massage head includes a base 120, a bracket 110 and a fixed ring cover 190, wherein the bracket 110 is disposed on the base 120, and the heating sheet 150 is disposed on a side of the bracket 110 away from the base 120. The fixed ring cover 190 is detachably connected to the base 120, and is enclosed with the base 120 to form a receiving space 191 with an upward opening, and the fixed ring cover 190 is used to press and fix the bracket 110, the heating sheet 150, the metal foil 170 and the non-metallic electrode sheet 180 on the base 120 to form a massage head with a complete surface.

[0094] Furthermore, the upper surface of the non-metallic electrode sheet 180 protrudes from the upper end surface of the fixed ring cover 190, and the protruding height is 0.1mm-0.3mm. The protruding portion of the non-metallic electrode sheet 180 contacts the user's massaged area, which is convenient for the user to identify the use area of ​​the massager and can effectively perform rotational massage on the user's massaged area.

[0095] See also Figure 6 In order to ensure insulation between the heating sheet 150 and the metal foil 170 while satisfying their respective power connections, a avoidance structure is provided on the base 120 and / or the metal foil 170. The heating sheet 150 has a bending portion, and the second conductive member 220 is electrically connected to the bending portion at the avoidance notch 111 to be insulated from the metal foil 170. Since the heating sheet 150 is located between the bracket 110 and the metal foil 170, the avoidance structure may be provided on the bracket 110, or the avoidance structure may be provided on the metal foil 170, or the avoidance structure may be provided on both the bracket 110 and the metal foil 170.

[0096] Optionally, the avoidance structure may be a avoidance notch or a avoidance depression. For example, when the avoidance structure is provided on the metal foil 170 and the avoidance structure is a avoidance depression, the avoidance depression may be recessed from the metal foil 170 toward the non-metallic electrode sheet 180, thereby forming an avoidance space between the metal foil 170 and the heating sheet 150. At this time, the bending portion of the heating sheet 150 may be located at the avoidance depression and electrically connected to the second conductive member 220.

[0097] Exemplarily, the avoidance structure is provided on the bracket 110, and the avoidance structure is an avoidance gap. The bracket 110 is provided with an avoidance gap 111 with an opening toward the metal foil 170, the bending portion of the heating sheet 150 extends toward the bracket 110 and is located in the avoidance gap 111, and the second conductive member 220 is electrically connected to the bending portion at the avoidance gap 111 to be insulated from the metal foil 170. Since the heating sheet 150 directly faces the second surface 162 of the carrier 160 wrapped with the metal foil 170, if the second conductive member 220 is set on the upper surface of the heating sheet 150 to achieve conductivity, on the one hand, it affects the flatness of the carrier 160 installed on the heating sheet 150, and on the other hand, it cannot be effectively insulated, which will cause the second conductive member 220 to contact the metal foil 170 and eventually cause the non-metallic electrode sheet 180 to short-circuit. By setting the bending portion, the second conductive member 220 is electrically connected to the bending portion at the avoidance notch 111 to be insulated from the metal foil 170, thereby ensuring that the heating sheet 150 can conduct electricity with the second conductive member 220 in the bottom direction toward the base 120, and avoiding the second conductive member 220 from contacting the metal foil 170, while also ensuring the flatness between the contact surfaces of the heating sheet 150 and the metal foil 170. It is understandable that in other embodiments, the avoidance structure on the bracket 110 can also be an avoidance recess.

[0098] Furthermore, the base also includes an insulating cover plate 140, which partially covers the avoidance gap 111 to form a through groove connected to the avoidance gap 111, and the bent portion extends from the through groove into the avoidance gap 111. Among them, an optional way for the insulating cover plate 140 to cover the avoidance gap 111 is: the insulating cover plate 140 and the base 120 are split structures, and the upper surface of the insulating cover plate 140 fits the upper surface of the heating plate 150, so that the heating plate 150 and the insulating cover plate 140 form a roughly flat upper surface. Among them, roughly flat means that the overall visual effect observed by the user is flat.

[0099] When this covering method is used, the area of ​​the insulating cover 140 is roughly consistent with the area of ​​the avoidance gap 111, which can effectively save the material of the insulating cover 140. The insulating cover 140 only needs to partially cover the avoidance gap 111, and it is also beneficial to form a roughly flat surface with the upper surface of the heating plate 150.

[0100] It should be noted that the substantially flat upper surface of the insulating cover plate 140 includes the specific situation that the upper surface thereof is inevitably not completely flat in the strict sense due to deviations caused by current processing and production limitations.

[0101] Among them, the insulating cover plate 140 partially covers the avoidance gap 111, forming a through groove connected to the avoidance gap 111. The part of the insulating cover plate 140 covering the avoidance gap 111 effectively ensures the insulation between the second conductive member 220 and the metal foil 170, preventing the current of the second conductive member 220 from being transferred to the metal foil 170, thereby causing the non-metallic electrode sheet 180 to short-circuit. The bent portion extends from the through groove into the avoidance gap 111 and is electrically connected to the second conductive member 220, so that the heating sheet 150 is energized and heated. Since the heating sheet 150 is in insulated contact with the metal foil 170, the heat of the heating sheet 150 can be transferred to the non-metallic electrode sheet 180 through the metal foil 170, thereby achieving a heating therapy effect.

[0102] like Figure 7 As shown, another optional way for the insulating cover plate 140 to cover the avoidance gap 111 is: the bracket 110 and the insulating cover plate 140 are integrally formed, the insulating cover plate 140 partially covers the opening of the avoidance gap 111, and the bent portion of the heating sheet 150 is passed downward from the insulating cover plate 140 to the avoidance gap 111, thereby ensuring that the bent portion of the heating sheet 150 is insulated from the metal foil 170, that is, the conductive part of the heating sheet 150 is disconnected from the metal foil 170 through the insulating cover plate 140 to ensure insulation. When this method is adopted, since the insulating cover plate 140 and the bracket 110 are integrally formed, it is easy to process, and at the same time reduces the assembly process, reduces the assembly error, and is conducive to improving the integrity of the base 120.

[0103] In some embodiments, a circuit board 130 is provided in the base 120 , and the circuit board 130 is provided below the heating plate 150 . The circuit board 130 is electrically connected to the first conductive member 210 and the second conductive member 220 , respectively, to connect the first conductive member 210 and the second conductive member 220 to a power source.

[0104] like Figure 8 , Fig. 9As shown, specifically, the circuit board 130 is provided with a first electrode connection terminal and a second electrode connection terminal, the second conductive member 220 includes a first connector 221 and a second connector 222, and the bending portion of the heating sheet 150 includes a first bending portion 151 and a second bending portion 152, wherein the first bending portion 151 and the second bending portion 152 are respectively fixedly connected and electrically connected to the first electrode connection terminal and the second electrode connection terminal through the first connector 221 and the second connector 222, the output electrodes of the first electrode connection terminal and the second electrode connection terminal are different, the first electrode connection terminal is connected to the positive electrode of the circuit board 130, and the second electrode connection terminal is connected to the negative electrode of the circuit board 130, and the first bending portion 151 of the heating sheet 150 is connected to the positive electrode of the circuit board 130 through the first connector 221 The second bent portion 152 of the heating sheet 150 is electrically connected to the second electrode connection end through the second connector 222 and connected to the negative electrode of the circuit board 130, so as to form a conductive loop for the heating sheet 150 and conduct electricity to the heating sheet 150. When the heating sheet 150 is powered on, it generates heat and transfers the heat to the metal foil 170, and transfers the heat to the non-metallic electrode sheet 180 through the metal foil 170.

[0105] The first connecting member 221 is a first rivet, the second connecting member 222 is a second rivet, and the circuit board 130 is provided with a first connecting ear 131 and a second connecting ear 132, which are respectively located corresponding to the first bending portion 151 and the second bending portion 152. The first connecting ear 131 and the second connecting ear 132 are respectively connected and electrically connected to the first bending portion 151 and the second bending portion 152 through the first rivet and the second rivet. The first rivet and the second rivet can well fix the heating sheet 150 on the circuit board 130, and are also easy to disassemble; due to the metal material characteristics of the rivet, it can also conduct the power supply to realize the power supply between the circuit board 130 and the heating sheet 150.

[0106] Furthermore, the circuit board 130 is provided with a third electrode connection terminal 133, the heating sheet 150 is provided with an air-avoiding hole 153, one end of the first conductive member 210 is electrically connected to the third electrode connection terminal 133, and the other end passes through the air-avoiding hole 153 in an insulated manner and abuts against and is electrically connected to the metal foil 170 to supply power to the metal foil 170. The first conductive member 210 is electrically connected to the metal foil 170, thereby providing a pulse current to the metal foil 170, and the pulse current is transmitted to the non-metallic electrode sheet 180, and the pulse current is provided to the user's massaged part through the non-metallic electrode sheet 180, thereby achieving a physical therapy effect. Since the heating sheet 150 is disposed between the circuit board 130 and the metal foil 170, there is a conductive loop between the heating sheet 150 and the circuit board 130 that is different from the metal foil 170, which is easy to interfere with the circuit between the first conductive member 210 and the metal foil 170, and the arrangement of the air-avoiding hole 153 avoids the short circuit of the non-metallic electrode sheet 180 caused by the conduction between the heating sheet 150 and the first conductive member 210, thereby ensuring the normal circuit connection between the first conductive member 210 and the metal foil 170. Among them, the first conductive member 210 can be a conductive spring pin or a rivet derived from the circuit board 130.

[0107] Please refer again Figure 5 , Figure 6 and Figure 7 Optionally, since the contact surface of the human neck is approximately a convex arc surface, in order to effectively adapt to the shape of the human neck and ensure that the non-metallic electrode sheet 180 can fit the neck, the carrier 160 is a concave arc shape, and the metal foil 170 and the non-metallic electrode sheet 180 are both flexible and deformable sheets. When the metal foil 170 and the non-metallic electrode sheet 180 are installed on the carrier 160, they can deform into a concave arc shape following the shape of the carrier 160, thereby effectively fitting the human neck.

[0108] Optionally, the non-metallic electrode sheet 180 is a conductive gel sheet or a silicone conductive sheet. Exemplarily, the non-metallic electrode sheet 180 is a conductive gel sheet and conducts electricity through the metal foil 170. Since the surface of human skin is covered with a layer of scaly stratum corneum, which is a poor conductor of electricity, when the non-metallic electrode sheet 180 is directly attached to the surface of the stratum corneum, it is not easy for the current to pass through the metal electrode sheet and conduct with the human skin, and energy concentration is likely to occur locally, causing tingling. Therefore, the present invention adopts the design of the non-metallic electrode sheet 180 as a conductive gel sheet, and the conductive gel sheet can be used to fill the gap in the scaly stratum corneum, so that the conductive gel sheet can directly contact the dermis under the stratum corneum of the human body, and then the conductive gel sheet and the part attached to the surface of the human skin can be fully electrically connected with the dermis, which increases the area of ​​electrical conduction, reduces local energy concentration, avoids tingling during use, and improves the user experience.

[0109] On the other hand, the gel electrode sheet can generate water vapor so that the non-metallic electrode sheet 180 forms a good fit with the skin. The carrier 160 is a plastic sheet, and the projection of the gel electrode sheet on the carrier 160 is located on the carrier 160. In this way, the carrier 160 has good water-proof and air-proof properties, which can effectively prevent water vapor from penetrating into the base 120, thereby avoiding corrosion of the components inside the base 120 or short circuit of the internal circuit of the noise. At the same time, the carrier 160 is a plastic sheet with good elasticity and plasticity, which can adapt to the shape of the mounting surface of the base 120 for mounting the electrode assembly 10 to achieve good fitting installation, and can have a relatively flat shape during manufacturing, transportation, and storage, which is convenient for manufacturing, transportation, and storage.

[0110] Optionally, the metal foil 170 is a copper foil or an aluminum foil, so as to have excellent electrical and thermal conductivity. Exemplarily, the metal foil 170 is a copper foil, which has excellent thermal conductivity and certain structural strength, and can effectively support the non-metallic electrode sheet 180 .

[0111] Optionally, the heating sheet 150 is a graphene sheet, the circuit board 130 is a flexible circuit board 130, a plurality of light-emitting elements 134 are provided on a side of the circuit board 130 facing the heating sheet 150, the metal foil 170 is provided with light-transmitting holes corresponding one to one with the light-emitting elements 134, and the carrier 160 on the metal foil 170 is a translucent material with a matte surface, which can produce a uniform light effect on the light emitted by the light-emitting elements 134.

[0112] The massage head 100 disclosed in this embodiment provides a pulse current to the metal foil 170 in a manner insulated from the heating sheet 150 through the first conductive member 210, and supplies power to the heating sheet 150 in a manner insulated from the metal foil 170 through the second conductive member 220, so that the heating sheet 150 generates heat and transfers the heat to the metal foil 170, thereby achieving electrical and thermal conductivity to the non-metallic electrode sheet 180 through the metal foil 170, which not only ensures the safety of user use, but also effectively improves the thermal conductivity efficiency of the non-metallic electrode sheet 180, thereby enhancing the user experience.

[0113] Furthermore, the fixed ring cover 190 and the bracket 110 form a snap-on detachable connection, and the metal foil 170 coated with the carrier 160 is pressed on the surface of the heating sheet 150 to form the massage head 100. Through the detachable connection of the fixed ring cover 190, it is convenient for users to disassemble and replace different parts during use, extend the service life, and save costs. At the same time, the electrode assembly 10 formed by the non-metallic electrode sheet 180, the metal foil 170 and the carrier 160 is detachably installed on the base 120. When the base 120 and the fixed ring cover 190 are disassembled, the electrode assembly 10 is disassembled relative to the base 120, so that the non-metallic electrode sheet 180 can be replaced. In particular, when the non-metallic electrode sheet 180 is damaged or dirty, the electrode sheet can be replaced in time to ensure that the non-metallic electrode sheet 180 always has excellent performance.

[0114] In addition, the non-metallic electrode sheet 180 , the metal foil 170 , and the heating sheet 150 are stacked without any gaps, making the structure of the massage head 100 thinner and lighter.

[0115] It should be noted that the massage head 100 of this embodiment can be used as an independent massage device or can be used in conjunction with a wearable massage device. When the massage head 100 of this embodiment is used as an independent massage device, it can be powered by a built-in power supply or an external power supply, and the user can hold the massage head 100 to massage the parts to be massaged, such as the neck, head, waist, feet, shoulders, legs, etc.

[0116] When the massage head 100 of this embodiment is used in a wearable massage device, the massage head 100 of this embodiment can be installed on the wearable massage device. In this case, the user does not need to hold it in hand, but can wear it on the body through the wearable massage device, so that the massage head 100 can be aimed at the user's massaged part to achieve massage. Optionally, the wearable massage device can be, but is not limited to, an eye massager, a neck massager, a head massager, a waist massager, a leg massager, or a shoulder massager.

[0117] The massage head 100, electrode assembly 10, neck massager and wearable massage device provided by the embodiment of the present invention are electrically connected to the first conductive member 210 in a manner of being insulated from the heating sheet 150 through the metal foil 170, and the heating sheet 150 is electrically connected to the second conductive member 220 in a manner of being insulated from the metal foil 170, so that the metal foil 170 serves as a conductive and heat-conductive layer of the non-metallic electrode sheet 180. While the metal foil 170 conducts electricity for the non-metallic electrode sheet 180 and provides pulse current, it can also efficiently conduct the heat generated by the heating sheet 150 being energized to the non-metallic electrode sheet 180, which has the beneficial effects of being able to effectively apply pulse current to the neck through the non-metallic electrode sheet 180, and being able to effectively improve the heat conduction efficiency of the non-metallic electrode sheet 180, and having high safety. In addition, the non-metallic electrode sheet 180 is in contact with the human neck, which can not only quickly conduct heat and pulse current to the human neck, but also has the beneficial effects of being soft and having good skin-fitting properties.

[0120] Optionally, the massager bracket 301 is approximately C-shaped, and is usually made of a material with elastic properties, such as silicone, rubber, etc., so that it is not only easy to wear on the human neck, but also has a certain degree of skin-friendliness. When the user uses the neck massager, the massager bracket 301 can be placed across the neck, so that the massage head 100 can be aligned with the neck part to be massaged and fit the neck skin to achieve massage.
