Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of an electrode assembly 100 applied to a massage apparatus.

The electrode assembly 100 includes a conductive contact layer 10, a conductive base material 20, and a support layer 30, which are sequentially stacked and integrally formed, the conductive base material 20 and the conductive contact layer 10 are in surface contact and electrically connected to each other, and the support layer 30 is connected to the conductive contact layer 10 and clamps the conductive base material 20.

The resistivity of the conductive base material 20 is smaller than that of the conductive contact layer 10, the conductive contact layer 10 is conductive in the stacking direction of the conductive base material 20 and the conductive contact layer 10 and is insulated in the rest directions except the stacking direction, the conductive contact layer 10 is used for contacting with a human body when the electric stimulation massager is used, the support layer 30 is used for supporting and keeping the conductive contact layer 10 and the conductive base material 20 not to deform, and further the rigidity of the electrode assembly 100 is increased, so that the shape of the electrode assembly 100 is favorably maintained, and the practical production and application of the electrode assembly 100 are facilitated.

When the conductive substrate 20 and the conductive contact layer 10 are not in laminated contact, a resistance value detected between any two points on one side of the conductive contact layer 10, which is far away from the conductive substrate 20, is a first resistance value; when the conductive base material 20 and the conductive contact layer 10 are in laminated contact, the resistance value obtained by detecting again between two points where the first resistance value is obtained before is the second resistance value which is smaller than the first resistance value; the conductive contact layer 10 is used to contact the human body when the electric stimulation massager is used.

Compared with the single use of the conductive contact layer 10, in the working process of the conductive contact layer 10, the current flows on the conductive contact layer 10, and the resistance value between any two points on the conductive contact layer 10 is larger than the resistance value between two points at the corresponding position on the electrode assembly 100 provided by the present application, in other words, the overall resistance value of the single use of the conductive contact layer 10 is larger than the resistance value of the electrode assembly 100 provided by the present application, so that a part of the electric energy is dissipated to the electric resistance of the single use of the conductive contact layer 10 during the working process, which causes electric energy waste and low utilization rate of the electric energy.

Based on this, under the condition that the electric quantity of the power supply is the same, the energy consumption of the conductive contact layer 10 used alone is larger, the corresponding power supply is charged relatively more frequently, and further the service life of the power supply is relatively shortened.

In the embodiment of the present invention, since the resistivity of the conductive base material 20 is smaller than the resistivity of the conductive contact layer 10, and after the conductive base material 20 is powered on, the current firstly flows through the conductive base material 20 and then flows to the conductive contact layer 10, that is, the conductive base material 20 with smaller resistivity is used as the power supply end of the conductive contact layer 10, compared with the case of using the conductive contact layer 10 alone as an electrode, the overall resistance value of the electrode assembly 100 is smaller, the energy consumed by the resistance is smaller, and more energy is used in physical therapy for human body, so the resistance of the electrode assembly 100 is smaller, the energy utilization rate is higher, and since the conductive contact layer 10 and the conductive base material 20 are both thinner, it is difficult to maintain their own shapes, the conductive contact layer 10 is easier to be scratched, and is not beneficial to production and application, therefore the electrode assembly 100 provided by the present invention further adds the supporting layer 30 which is in laminated contact with the conductive contact layer 10 and the conductive base material 20 and is integrally formed, therefore, the thickness of the electrode assembly 100 can be increased, the rigidity of the electrode assembly 100 can be increased, the shape of the electrode assembly 100 can be maintained, the practical production and application are facilitated, and the conductive contact layer 10 can be effectively prevented from being scratched.

In some embodiments, as shown in fig. 2, the conductive substrate 20 has a connection hole 21, the support layer 30 and the conductive contact layer 10 are connected through the connection hole 21, and the support layer 30 and the conductive contact layer 10 are further compositely connected with the conductive substrate 20. The support layer 30 and the conductive contact layer 10 are also bonded or press-fit connected to the conductive substrate 20 by a conductive adhesive, for example.

In other embodiments, the support layer 30 and the conductive contact layer 10 are compositely connected with the conductive substrate 20, and the peripheral side of the support layer 30 is connected with the peripheral side of the conductive contact layer 10.

As shown in fig. 3, the conductive contact layer 10 includes conductive particles 11 and an elastic matrix 13, the elastic matrix 13 is provided with a plurality of pores 130 extending along the stacking direction, the conductive particles 11 are filled in the pores 130, the conductive particles 11 are electrically contacted with the conductive substrate 20, and the conductive particles 11 guide the current to the skin of the human body to perform physical therapy on the local area of the human body.

Elastic matrix 13 can be elastic materials such as silica gel layer, rubber layer, and elastic matrix 13 has good flexibility, and deformability is strong, and then can be used to different application scenarios, for example as the physiotherapy electrode on the cervical vertebra massage appearance, can warp along with the deformation of cervical vertebra massage appearance to the human cervical vertebra of adaptation difference. The elastic matrix 13 itself is not electrically conductive, and the conductive particles 11 are filled in the pores 130 on the elastic matrix 13, and the conductive contact layer 10 is electrically conductive only in the stacking direction and is insulated in the remaining directions except the stacking direction.

The conductive particles 11 can be at least one of silver, gold, silver-coated copper, zinc and titanium, and the conductive particles 11 of various types not only have the conductive function, but also have the bactericidal function, and have good skin-friendly performance on human skin, thereby having good safety on human body.

The conductive contact layer 10 can be added with a toner, the toner is titanium dioxide, the titanium dioxide has strong covering power, strong tinting strength and good weather resistance, and the toner can modulate the color of the elastic matrix 13 into different colors to adapt to different application occasions, for example, the elastic matrix 13 is modulated into the color similar to the skin of a human body.

Specifically, the conductive particles 11 and the elastic matrix 13 are kneaded to form the conductive contact layer 10, the conductive particles 11 are in a dispersed phase in the conductive contact layer 10, and the elastic matrix 13 is in a continuous phase, so that the conductive contact layer 10 is conductive in the stacking direction and insulating in the remaining directions other than the stacking direction.

The supporting layer 30 may be made of the same material as the conductive contact layer 10, so that the conductive contact layer 10 and the supporting layer 30 may be simultaneously formed on both sides of the conductive substrate 20. The supporting layer 30 may be made of a material different from that of the conductive contact layer 10, for example, the supporting layer 30 is made of an elastic material such as silicone rubber, etc., and after the supporting layer 30 and the conductive substrate 20 are stacked, the conductive contact layer 10 is formed on one side of the conductive substrate 20, so that the conductive contact layer 10 is connected to the supporting layer 30 and cooperates with the supporting layer 30 to clamp the conductive substrate 20. Further, after the conductive contact layer 10 is connected to the conductive substrate 20, a pressing process is performed again to improve the conductivity between the conductive contact layer 10 and the conductive substrate 20, so that the conductive effect of the conductive contact layer 10 is better.

With reference to fig. 1 and fig. 2, the conductive substrate 20 may be a conductive cloth, a conductive gauze, a conductive foam, a conductive metal foil, etc., and the various conductive substrates 20 have good flexibility and strong deformability, and are suitable for different application scenarios.

For example, the conductive substrate 20 is a conductive cloth having a connection hole 21, the conductive cloth is formed by vacuum plating a woven cloth (e.g., a fiber cloth), and the plating metal may be nickel-copper alloy. The folding performance of the conductive cloth is good, the conductive cloth is not easy to crease after being folded or kneaded for many times, and the conductive cloth can not be broken due to stress fatigue even after being folded for many times.

In this embodiment, the conductive substrate 20 is a conductive gauze. Specifically, the conductive gauze is in a grid shape, the conductive contact layer 10 can penetrate through the mesh of the conductive gauze when in a fluid state, i.e. the mesh can be used as the connection hole 21 to connect with the support layer 30 and the conductive gauze, i.e. the support layer 30 and the conductive contact layer 10 penetrate through the mesh of the conductive gauze, and then the conductive contact layer 10 is solidified, so that the support layer 30, the conductive substrate 20 and the conductive contact layer 10 are integrated into a whole structure, thereby improving the adhesive force of the conductive contact layer 10 and the conductive gauze, improving the connection stability of the conductive contact layer 10, the conductive gauze and the supporting layer 30, and because the good contact nature of conductive contact layer 10 and electrically conductive gauze is favorable to promoting the electric conductivity of electrically conductive contact layer 10 in range upon range of orientation, is favorable to eliminating because of the extra resistance that produces because of the contact property between electrically conductive contact layer 10 and the electrically conductive gauze to further improve energy utilization.

The conductive mesh has 50-120 mesh openings per square centimeter. Research experiments show that the conductive gauze with the specification can ensure that the conductive gauze has enough adhesive force with the conductive contact layer 10, and the connection stability of the electrode assembly 100 is improved; on the other hand, the conductive mesh has high toughness, and the electrode assembly 100 can have good resilience when deformed by a force.

The conductive gauze is made of polypropylene material and the like through vacuum adsorption and electroplating. The electroplated metal can be nickel-copper alloy, the conductive gauze is not easy to crease after being folded or kneaded for many times, and the conductive gauze can not be broken due to stress fatigue even after being folded for many times. When the electrode assembly 100 is applied to the cervical vertebra massager, the electrode assembly 100 is not easy to generate creases along with the use of the cervical vertebra massager, and the condition of poor contact between the creases and the skin can be avoided.

In this embodiment, the conductive screen has a resistance of between 1 and 20 ohms. Research experiments show that the electrode assembly 100 adopting the conductive gauze of the specification can achieve a self-heating effect, the electrode assembly 100 does not need to be additionally provided with a heating layer, and further the functionality of the electrode assembly 100 is improved, so that the electrode assembly 100 can also be applied to a heating scene, and compared with similar products additionally provided with the heating layer, the electrode assembly 100 is simple in structure and high in production efficiency. If the resistance of the conductive gauze exceeds 20 ohms, the temperature rise is slow, and instant heating cannot be realized; if the resistance of the conductive gauze is less than 1 ohm, the temperature rise is fast, a user is easily scalded, and the power consumption is large. It has been found through experimental studies that the electrode assembly 100 can perform a good instant heating function when the electric resistance of the conductive gauze is between 1 to 20 ohms, and the generated temperature can be well applied to the skin of the user.

In the present embodiment, the thickness of the conductive contact layer 10 and the support layer 30 in the stacking direction is 0.05mm to 0.25mm, and the thickness of the conductive base material 20 in the stacking direction is 0.1mm to 0.3 mm. It has been found through research and experiment that the electrode assembly 100 formed by the conductive contact layer 10, the conductive base material 20 and the support layer 30 of the above specifications has sufficient flexibility, and the conductive contact layer 10 is not easily scratched. When the thicknesses of the conductive contact layer 10 and the support layer 30 are less than 0.05mm, the conductive contact layer 10 and the support layer 30 are easily scratched; when the thicknesses of the conductive contact layer 10 and the support layer 30 are greater than 0.25mm and the thickness of the conductive base material 20 is greater than 0.3mm, the electrode assembly 100 is brittle and cracks are easily generated in the electrode assembly 100. Therefore, when the thicknesses of the conductive contact layer 10 and the support layer 30 are 0.05mm to 0.25mm, and the thickness of the conductive base material 20 is 0.1mm to 0.3mm, the electrode assembly 100 has appropriate rigidity, is not easily deformed and scratched, and is not easily cracked, and the above dimensional limitations can satisfy the effect of electrotherapy on the human body, and also make the entire thickness of the electrode assembly 100 thinner, and the resistance is smaller, which is advantageous for improving the energy utilization rate of the electrode assembly 100.

Further, the thickness of the support layer 30 is smaller than the thickness of the conductive contact layer 10. The thickness of the conductive contact layer 10 is relatively thick, so that the conductive contact layer 10 is used as an exposed layer contacting with the skin, the toughness is relatively strong, and the conductive substrate 20 can be effectively prevented from being exposed due to tearing of the conductive contact layer 10.

In some embodiments, as shown in fig. 1, there is only one conductive substrate 20 between the support layer 30 and the conductive contact layer 10. In other embodiments, as shown in fig. 4, a plurality of conductive substrates 20 are disposed between the support layer 30 and the conductive contact layer 10, and the plurality of conductive substrates 20 are isolated and insulated from each other, i.e., a plurality of conductive substrates 20 are disposed on a side of the same conductive contact layer 10 facing the support layer 30, so that the electrode assembly 100 can be simultaneously connected to the positive and negative electrodes of the power source.

Based on this, the present application further provides a cervical vertebra massage apparatus 200, referring to fig. 5, fig. 5 is a schematic structural diagram of an embodiment of the cervical vertebra massage apparatus provided by the present application.

The cervical vertebra massager 200 comprises an elastic support 210 and the electrode assembly 100 as described above, wherein the electrode assembly 100 is disposed in the elastic support 210, and the conductive contact layer 10 protrudes from the elastic support 210 so as to be in contact with the skin of the neck of the human body.

Specifically, the cervical vertebra massage apparatus 200 includes a power source, an elastic support 210, and an electrode assembly 100. The power can make rechargeable batteries such as lithium cell, button cell or lead accumulator, and the power supplies power for electrode subassembly 100, and elastic support 210 is the arc setting and elastic support 210 has good elasticity to and electrode subassembly 100 also has good elasticity, therefore electrode subassembly 100 can warp along with elastic support 210 in order to adapt to different human necks, therefore this cervical vertebra massager 200 can be better with human skin laminating contact, area of contact is big, and is good to human physiotherapy effect.

The cervical vertebra massager 200 further comprises two clamping arms 240, a power supply is arranged in the clamping arms 240, the two clamping arms 240 are respectively connected to two ends of the elastic support 210, and the two clamping arms 240 are folded to prevent the cervical vertebra massager 200 from falling off when being worn on the neck of a human body.

Since the energy utilization rate of the electrode assembly 100 is relatively improved in the present application, the available time period of the power supply is relatively increased, and thus the volume of the power supply can be appropriately reduced to facilitate the miniaturization of the cervical massager 200.

In some embodiments, as shown in fig. 5, the electrode assemblies 100 of the cervical spine massager 200 are divided into two groups, corresponding to the two conductive contact layers 10. The elastic support 210 is correspondingly provided with two windows 212, and the conductive contact layer 10 protrudes from the corresponding window 212 so as to be in contact with the skin of the human body.

In other embodiments, the electrode assembly 100 of the cervical vertebra massager 200 is a set, the conductive contact layer 10 is an integral structure, and two conductive substrates 20 are respectively stacked on the conductive contact layer 10. The elastic support 210 is correspondingly provided with a window 212, the electrode assembly 100 is mounted on the elastic support 210, and the conductive contact layer 10 protrudes from the window 212, so that the elastic support 210 only needs to be provided with one mounting position of the electrode assembly 100, the structure is simpler compared with the elastic support 210 provided with two or more mounting positions, the production cost is lower, and the mounting efficiency of the electrode assembly 100 can be improved.

In other embodiments, the electrode assembly 100 and the elastic holder 210 may be integrally formed. For example, the elastic support 210 is made of the same material as the elastic matrix 13, the electrode assembly 100 may be prefabricated, and then the prefabricated electrode assembly 100 may be placed in a mold of the elastic support 210 as an insert, and the local temperature of the mold may be controlled to lower the mold temperature at the position where the electrode assembly 100 is placed, so as to integrally form the elastic support 210 and the elastic matrix 13. Certainly, the elastic support 210 and the conductive contact layer 10 may be integrated at a time, and the conductive particles 11 are arranged in the preset conductive region by applying an electric field to form different conductive electrodes, so that the production process is better, and the cost is saved. For example, the elastic support 210 is a silicone support, the support layer 30 and the conductive contact layer 10 are both conductive silicone, and the silicone support 210 and the conductive silicone 10 are integrally formed.

The application discloses an electrode assembly applied to a massager and a cervical vertebra massager, wherein the resistivity of a conductive base material is smaller than that of a conductive contact layer, the conductive contact layer is conductive in the stacking direction and is insulated in the other directions except the stacking direction, so that after the conductive base material is electrified, current flows through the conductive base material firstly and then flows along the stacking direction of the conductive contact layer, the resistivity of the conductive contact layer is smaller than that of the conductive contact layer which is conductive in all directions, and the conductive base material with smaller resistivity is used as a power supply end for the conductive contact layer, relatively speaking, the overall resistance value of the electrode assembly is smaller, the energy consumed by resistance is smaller, more energy is used for physical therapy on a human body, the energy utilization rate is higher, and the conductive contact layer and the conductive base material are thinner, so that the self shape is difficult to keep, and the conductive contact layer is easier to be scratched, the electrode assembly is not beneficial to production and application, the supporting layer which is in laminated contact with the conductive contact layer and the conductive base material and is integrally formed is further added, the rigidity of the electrode assembly can be improved by the supporting layer, the shape of the electrode assembly can be kept, the actual production and application are facilitated, and the conductive contact layer can be effectively prevented from being scratched.

The above description is only an example of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings, or which are directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present application.
