Detailed Description

Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.

Referring to fig. 1-2, an electrode assembly 20 according to an embodiment of the present invention is described, in which a liquid containing portion 33 is disposed on an electrode pad 28 of the electrode assembly 20, and the electrode assembly 20 can make the resistance of the skin on the contact area between the electrode assembly 20 and the neck of the user uniform by a conductive liquid applied on the liquid containing portion 33, so as to effectively eliminate the pricking feeling of the skin on the contact area between the electrode pad 28 of the electrode assembly 20 and the neck of the user due to excessive local current. The use experience of the user can be improved. The electrode assembly 20 of the present embodiment can also be widely applied to various neck massage apparatuses 100.

As shown in conjunction with fig. 1 and 2, an electrode assembly 20 according to an embodiment of the present invention may include: the electrode sheet 28, electrode sheet 28 is provided with a plurality of liquid containing parts 33 for containing the conductive liquid, liquid containing parts 22 are distributed on the inner side surface of electrode sheet 28, at least a part of the conductive liquid coated on the inner side surface of electrode sheet 28 is contained in liquid containing parts 33, and the inner side surface of electrode sheet 28 is a surface adhered to the skin. That is, the liquid containing portion 33 is provided on the inner side surface of the electrode sheet 28, and the liquid containing portion 33 may make the conductive liquid, which may be a good conductive material, be uniformly distributed, for example: water, and the like.

Further, the inner surface of the electrode pad 28 is the surface of the electrode pad 28 that is attached to the neck of the human body, and the uniform distribution of the conductive liquid on the liquid containing portion 33 can make the electrode pad 28 and the stratum corneum of the skin on the neck contact region uniformly contact the conductive liquid, and the conductive liquid can permeate into the gaps of the scale-shaped microstructure of the stratum corneum of the human body, so that the resistance of the stratum corneum of the skin is reduced, and the resistance of the skin on the neck contact region becomes uniform. Because neck massager 100 voltage is stable, and the resistance of skin on the neck contact area is even, so electrode slice 28 just also is invariable with the electric current that skin received on the neck contact area, effectively eliminates electrode slice 28 among neck massager 100 and the skin on the contact area of neck and probably produces the sense of sting because local electric current is too big, has promoted user's use experience.

Further, as shown in fig. 1 and 2, the liquid containing portion 33 is a groove and/or a hole, and the groove or the hole is plural. That is, the liquid containing portion 33 may be a groove, a hole, or a combination of a groove and a hole. Specifically, the grooves or holes can contain the conductive liquid, the grooves or holes divide part of the conductive liquid into a plurality of parts, the parts are stored, the rest less conductive liquid exists on the surface of the electrode plate 28, the conductive liquid in each groove or hole and the conductive liquid on the surface of the electrode plate 28 are not aggregated into flowable water bead particles due to less reasons, and only the bottom and the peripheral wall surfaces of the grooves or holes and the surface of the electrode plate 28 are wetted, so that the electrode plate 28 is ensured to be in contact with the skin of a user in a wet state, the resistance of the stratum corneum of the skin is reduced, and meanwhile, the conductive liquid can be prevented from directly flowing to the back of the person from the compact and smooth electrode plate 28 and being wetted by clothes of the user.

Optionally, the liquid container 33 is one of a circular hole, a circular groove, a polygonal hole and a polygonal groove, wherein the polygonal hole and the polygonal groove may be a square hole or a square groove, but not limited thereto, and thus, by such an arrangement, on the premise of not affecting each functional requirement of the electrode assembly 20, the variety of products can be enriched, so that the products can satisfy the preferences of various users, and the popularization and application of the products can be promoted.

Further, as shown in FIG. 1 and FIG. 2, when the liquid containing portion 33 is a circular hole or a circular groove, the inner diameter of the liquid containing portion 33 is a, wherein a is greater than 0 and less than or equal to 50 μm. Specifically, the liquid containing parts 33 are a plurality of grooves or holes, and since the diameter of human hair is between 70 μm and 80 μm, in order to prevent the grooves or holes on the electrode sheet 28 that is in close contact with the neck skin from trapping hair when the user wears the neck massager 100, the inner diameter of the grooves or holes can be controlled to be less than 50 μm, thereby preventing the grooves or holes from trapping hair. That is, the inner diameter a of each groove or hole may range from 0 < a ≦ 50 μm. In addition, when the liquid containing part 33 is a polygonal hole or a polygonal groove, the size requirement of the liquid containing part 33 also needs to satisfy not only that the liquid containing part 33 can contain the conductive liquid to prevent the conductive liquid from wetting the clothes of the user, but also that the hair of the liquid containing part 33 is prevented from being caught.

Referring to fig. 1 and 2, the thickness of the electrode sheet 28 is b, wherein b is greater than or equal to 1mm and less than or equal to 5 mm. Specifically, since the electrode pads 28 are formed by sintering, if the electrode pads 28 are designed to be too thin, the electrode pads 28 are easily perforated during sintering, and thus, when the conductive liquid is applied, a liquid leakage phenomenon occurs, so that the liquid containing portion 33 cannot store the conductive liquid, thereby damaging the neck massager 100.

Further, the electrode tabs 28 need to be welded to other electrode assemblies 20, so if the electrode tabs 28 are designed to be too thin, welding is easily deformed when the electrode tabs 28 are welded to other electrode assemblies 20, resulting in a failure in connection.

Further, if the electrode plate 28 is designed to be too thick, not only the weight of the entire neck massager 100 is increased and the user feels not light enough, but also unnecessary waste of raw materials is caused, and the production cost is increased. Therefore, the thickness of the electrode plate 28 can be designed to be 1mm or more and b or less than 5 mm. The quality and the production cost of the product can be balanced as much as possible.

Further, the depths of the liquid containing portions 33 are different, for example, when the liquid containing portions 33 are circular grooves, the depths of at least two circular grooves are different, that is, when the liquid containing portions 33 are circular grooves, the depths of at least two liquid containing portions 33 are different, because the inclination angles of the electrode pads 28 are different when the electrode assembly 20 is attached to the necks of different users, and if the deep portions of the liquid containing portions 33 are designed to be the same, then when the user uses the neck massager 100, two design defects that a lot of or no conductive liquid comes out from the conductive liquid will occur, and designing the liquid containing portions 33 into circular grooves with different depths can make the conductive liquid on the attachment positions of the electrode pads 28 and the necks of the human body substantially the same when the electrode pads 28 are at different inclination angles or the electrode pads 28 are at different attachment positions of the human body. In addition, when the liquid storage parts 33 have other shapes, it is necessary to satisfy the condition that the depths of at least two liquid storage parts 33 are different.

Further, the electrode sheet 28 may be a stainless steel sheet, a titanium sheet, a copper sheet, or an aluminum sheet. Titanium is light and corrosion resistant, and is not easy to generate rejection reaction with human skin; copper and aluminum have good electric and thermal conductivity, and the cost of aluminum is lower. Since the liquid containing part 33 of the electrode plate 28 needs to be coated with the conductive liquid, in this case, stainless steel is preferably used as the material of the electrode plate 28, and stainless steel is preferably used as the material of the electrode plate 28, so that the electrode plate 28 is not rusted in a humid environment, and compared with the above, stainless steel is more economical, the production cost is saved, and the quality of the product and the production cost are balanced as much as possible.
