[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components.

Unless otherwise specified, "plurality" means two or more.

[0051] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0052] Please also read Figures 1 to 3 , Figure 1 FIG. 1 is an overall schematic diagram of a massage head assembly 100 for a neck massager according to the present invention. Figure 2 is a schematic cross-sectional exploded view of the massage head assembly 100, Figure 3 1 is a side cross-sectional view of a base body included in the massage head assembly 100. The massage head assembly 100 includes a massage head 1 and a gel cover 2. The gel cover 2 is used to be sleeved on the massage head 1.

[0053] The gel cover 2 includes a base 21 made of a flexible or elastic material, and the base 21 is configured in a sleeve shape. A first receiving cavity S1 is provided on a first side 211 of the base 21. The first receiving cavity S1 is adapted to the shape of the massage head 1 and is used to receive the massage head 1 so that the base 21 can be sleeved onto the massage head 1, thereby achieving the goal of sleeve-mounting the gel cover 2 on the massage head 1.

[0054] Please also read Figure 4 The second side 212 of the base 21 is provided with a second receiving cavity S2 connected to the first receiving cavity S1, and the second receiving cavity S2 is used to receive a conductive gel sheet 3, wherein when the conductive gel sheet 3 is received in the second receiving cavity S2 and the base 21 is sleeved on the massage head 1, the conductive gel sheet 3 is used to be electrically connected to the electrode sheet 11 provided at the end of the massage head 1, and is used to contact the part of the human neck to be massaged when massaging the part of the human neck to be massaged, so as to achieve pulse electric stimulation massage of the part of the human neck to be massaged.

[0055] Therefore, in the present invention, a gel sleeve 2 is sleeved on the massage head 1, and the gel sleeve 2 can further accommodate a conductive gel sheet 3 for electrically connecting to the electrode sheet on the massage head 1. The conductive gel sheet 3 is used to contact the human skin. The conductive gel sheet 3 can be filled into the gaps in the squamous stratum corneum, so that the electrode sheet on the massage head 1 is electrically in contact with the dermis layer under the stratum corneum of the human body, so that the electrode sheet can be fully electrically connected with the dermis layer of the human skin at the part to which the massage head 1 is attached, thereby increasing the effective area of ​​electrical conduction, reducing local energy concentration, and avoiding tingling during use.

[0056] In addition, since the base 21 is made of a flexible or elastic material, it can deform to a certain extent following the shape of the massage head 1, which is more conducive to the fit between the base 21 and the massage head 1, and the installation fit is tighter. Compared with a hard base, the flexible-elastic base is soft when in contact with the human body and will not make the human body feel hard, which can bring a better wearing experience.

[0057] In some embodiments, the conductive gel sheet 3 is a structure included in the gel sleeve 2, that is, the gel sleeve 2 includes the base 21 and the conductive gel sheet. The conductive gel sheet 3 can be detachably received and fixed in the second receiving cavity S2 of the base 21 of the gel sleeve 2, or can be integrally formed with the base 21 and disposed in the second receiving cavity S2 of the base 21 of the gel sleeve 2.

[0058] In other embodiments, the conductive gel sheet 3 is a structure independent of the gel sleeve 2, that is, in other embodiments, the gel sleeve 2 may not include the conductive gel sheet 3. The gel sleeve 2 and the conductive gel sheet 3 may be independently produced or even sold independently. The conductive gel sheet 3 may be accommodated in the second accommodation cavity S2 when a neck massager is needed for massage. The conductive gel sheet 3 may be detachably accommodated in the second accommodation cavity S2 of the gel sleeve 2.

[0059] like Figure 3 and Figure 4 As shown, in some embodiments, the base 21 also includes a spacer 213 arranged on the inner wall B1 of the base 21, and the spacer 213 extends in a direction away from the inner wall B1. The spacer 213 divides the internal space of the sleeve-shaped base 21 into the first receiving cavity S1 and the second receiving cavity S2. The spacer 213 is provided with a through hole K1, and the first receiving cavity S1 and the second receiving cavity S2 are connected through the through hole K1.

[0060] That is, in some embodiments, the first receiving cavity S1 and the second receiving cavity S2 are two receiving cavities substantially separated by the partition portion 213 .

[0061] Among them, the spacer 213 can be a roughly plate-shaped structure that extends straight from various positions on the inner circumference of the inner wall B1 of the base 21. The spacer 213 can extend a preset distance in the direction away from the inner wall B1, and the preset distance is smaller than the radius of the base 21, so that the through hole K1 is formed in the middle of the spacer 213.

[0062] In other embodiments, the base 21 may not include the spacer 213, that is, the inner side wall of the base 21 may not be provided with the spacer 213, and the first receiving cavity S1 and the second receiving cavity S2 are spaces corresponding to receiving the massage head 1 and the conductive gel sheet 3 when the massage head 1 and the conductive gel sheet 3 are received in the internal space of the base 21, respectively.

[0063] In some embodiments, when the base 21 includes the spacer 213 , a region of the spacer 213 where no through hole K1 is provided forms a depression 214 , and the depression 214 surrounds the through hole K1 .

[0064] Among them, the first surface F1 of the sink 214 facing the first side 211 and the inner wall B1 of the base located between the sink 214 and the first side 211 constitute the inner wall surface of the first receiving cavity S1. When the first receiving cavity S1 receives the massage head 1 therein, the outer surface of the massage head 1 fits with the inner wall surface of the first receiving cavity S1.

[0065] Among them, the outer surface of the massage head 1 can fit tightly with the inner wall surface of the first receiving cavity S1, and the first receiving cavity S1 of the base 21 tightly wraps the massage head 1, so that the installation fit between the base 21 and the massage head 1 is tighter. After the massage head 1 is fitted with the base 21, it can maintain almost the same original shape as the massage head 1.

[0066] The first receiving cavity S1 mentioned above is adapted to the shape of the massage head 1 , and the external shape of the massage head 1 may be substantially the same as the cavity shape of the first receiving cavity S1 of the base 21 .

[0067] The size of the first receiving cavity S1 may be slightly smaller than that of the massage head 1. Thus, when the massage head 1 is received in the first receiving cavity S1, since the base 21 is made of a flexible material or an elastic material, the first receiving cavity S1 is slightly deformed to generate an elastic restoring force to tightly wrap the massage head 1.

[0068] When the conductive gel sheet 3 is received in the second receiving cavity S2 , the second surface F2 of the sink 214 facing the second side 212 is in contact with a portion of the surface 31 of the conductive gel sheet 3 away from the second side F2 .

[0069] That is, when the conductive gel sheet 3 is accommodated in the second receiving cavity S2, a partial area of ​​the surface 31 of the conductive gel sheet 3 facing the second receiving cavity S2 is attached to the second surface F2 of the sinking platform 214, and the sinking platform 214 can be carried on the sinking platform 214 as a carrier.

[0070] The conductive gel sheet 3 and the second surface F2 of the sink 214 may be bonded by local glue dispensing to increase the accommodation stability of the conductive gel sheet 3 in the second accommodation cavity S2.

[0071] In some embodiments, the side periphery 32 of the conductive gel sheet 3 is tightly fitted with the inner side wall B1 of the base 21 located between the sink 214 and the second side 212 .

[0072] Among them, the second surface F2 of the sink 214 facing the second side 212 and the inner side wall B1 of the base 21 located between the sink 214 and the second side 212 constitute the inner wall surface of the second receiving cavity S2. In some embodiments, the side circumference 32 of the conductive gel sheet 3 and the surface 31 facing the second receiving cavity S2 are tightly fitted with the inner wall surface of the second receiving cavity S2. The tight fit refers to the fact that there is no gap between the side circumference 32 of the conductive gel sheet 3 and the surface 31 facing the second receiving cavity S2 and the inner wall surface of the second receiving cavity S2, which can be achieved according to existing processes or means. For example, it can be an interference fit or a seamless fit, thereby increasing the accommodation stability of the conductive gel sheet 3 in the second receiving cavity S2.

[0073] The side periphery 32 of the conductive gel sheet 3 and the inner side wall B1 of the base 21 between the sink 214 and the second side 212 may also be further bonded by local glue dispensing to further increase the accommodation stability of the conductive gel sheet 3 in the second accommodation cavity S2.

[0074] See also Figure 5 ,for Figure 4 A local enlarged view of area A0 in Figure 5 As shown, the thickness D0 of the conductive gel sheet 3 is greater than the depth D1 between the second surface F2 of the sink 214 and the end of the second side 212 of the substrate 21, and the conductive gel sheet 3 at least partially protrudes from the second side 212 of the substrate 21 to the outside of the substrate 21. In this way, the conductive gel sheet 3 can be ensured to contact with human skin.

[0075] Among them, the depth D1 between the second surface F2 of the sink 214 and the end of the second side 212 of the base 21 is also the depth of the second receiving cavity S2, that is, the thickness D0 of the conductive gel sheet 3 is greater than the depth D1 of the second receiving cavity S2, so that it at least partially protrudes outside the second receiving cavity S2.

[0076] In some embodiments, the height D2 of the portion of the conductive gel sheet 3 protruding from the second side 212 of the substrate 21 is between 0.3 mm and 2.5 mm. That is, the height D2 of the portion of the conductive gel sheet 3 protruding from the second side 212 of the substrate 21 is greater than or equal to 0.3 mm and less than or equal to 2.5 mm.

[0077] In some embodiments, the depth D1 between the second surface F2 of the sink 214 and the end of the second side 212 of the base 21 is between 1-4 mm. That is, the depth D1 between the second surface F2 of the sink 214 and the end of the second side 212 of the base 21, that is, the depth of the second receiving cavity S2, is greater than or equal to 1 mm and less than or equal to 4 mm.

[0078] Thus, the thickness D0 of the conductive gel sheet 3 may be the sum of the depth D1 between the second surface F2 of the sink 214 and the end of the second side 212 of the substrate 21 and the height D2 of the portion of the conductive gel sheet 3 protruding from the second side 212 of the substrate 21, and the thickness D0 of the conductive gel sheet 3 may be a value between 1.3 and 6.5 mm. Thus, by setting the depth D1 and the like, the conductive gel sheet 3 can be well positioned and accommodated in the second accommodation cavity S2 while being ensured to be not too thick, thereby avoiding energy loss caused by a large resistance due to an excessive thickness of the conductive gel sheet 3.

[0079] Among them, Figure 3-5 As shown, the depth of the second accommodating cavity S2 is significantly smaller than the depth of the first accommodating cavity S1; that is, the distance between the second surface F2 of the sink 214 and the end of the second side 212 of the base 21 is significantly smaller than the distance between the first surface F1 of the sink 214 and the end of the first side 211 of the base 21.

[0080] See also Figure 6 , is a side cross-sectional view of the base 21 in another embodiment containing the conductive gel sheet 3. The edge of the sink 214 connected to the through hole K1 has a circular chamfer A1, and is used to carry the conductive gel sheet 3. The portion of the conductive gel sheet 3 corresponding to the through hole K1 is recessed in the through hole K1 to contact and electrically connect with the electrode sheet of the massage head.

[0081] That is, the portion of the conductive gel sheet 3 corresponding to the through hole K1 is recessed in the through hole K1, and a portion is located in the first receiving cavity S1 or flush with the first surface F1 of the sink 214 facing the first receiving cavity S1 / first side 211. When the massage head 1 is received in the first receiving cavity S1, the electrode sheet 11 of the massage head 1 contacts the first surface F1 of the sink 214 facing the first receiving cavity S1 / first side 211, and contacts the portion of the conductive gel sheet 3 recessed in the through hole K1 and is electrically connected.

[0082] Among them, due to the provision of the arc chamfer A1, the conductive gel sheet 3 can be an overall curved surface with an arc transition, thereby reducing the sense of concavity and convexity, so that when the massage head 1 is covered with the gel sleeve 2 containing the conductive gel sheet 3, it can be well adapted to the human neck.

[0083] Please also read Figure 7 , is a schematic diagram of the decomposition of the substrate 21 and the conductive gel sheet 3 in a separated state in one embodiment of the present invention. Figure 7 As shown, the sink 214 is annular, and the hollow area surrounded by the annular sink 214 is the through hole K1. When the sink 214 is annular, the through hole K1 is a circular hole.

[0084] In some embodiments, the radial width of the depression 214 is between 3-6 mm, that is, the distance between the edge of the depression 214 connected to the through hole K1 and the inner side wall B1 of the base 21 is between 3-6 mm, that is, greater than or equal to 3 mm and less than or equal to 6 mm.

[0085] Preferably, the radial width of the sink 214 is 4.5 mm.

[0086] In some embodiments, the through hole K1 formed by the sink 214 may also be a square hole, a polygonal hole, an irregular-shaped hole or other through holes.

[0087] See also Figure 8 , which is a schematic top view of the base 21 in other embodiments of the present invention. In other embodiments, the spacer 213 may be a strip-shaped structure extending straightly from a plurality of preset positions on the same plane of the inner circumference of the inner side wall B1 of the base 21. For example, Figure 8 As shown, there may be four spacers 213 , which extend symmetrically from the inner side wall B1 of the base 21 and are not connected.

[0088] That is, in other embodiments, the spacer 213 can be a plurality of mutually spaced strip structures extending from the same plane of the inner wall B1 of the base 21, and the plurality of strip structures can support the conductive gel sheet 3, and the gaps between the strip structures can increase the contact area between the conductive gel sheet 3 and the electrode sheet 11 of the massage head 1 accommodated in the first accommodation cavity S1, thereby improving the conductive performance.

[0089] Please return to Figure 3-Figure 5The base 21 includes a first opening 22 located on the first side 211 and a second opening 23 located on the second side 212. The first opening 22 is a receiving opening of the first receiving cavity S1. The massage head 1 is received into the first receiving cavity S1 from the first opening 22. The second opening 23 is a receiving opening of the second receiving cavity S2. The conductive gel sheet 3 is received into the second receiving cavity S2 from the second opening 23.

[0090] like Figure 3 As shown, the inner diameter of the first receiving cavity S1 gradually increases from the first opening 22 to the second receiving cavity S2.

[0091] Furthermore, the diameter of the first opening 22 is smaller than the outer diameter of the massage head 1, and the inner diameter of the first receiving cavity S1 is equal to or slightly smaller than the outer diameter of the massage head 1. Therefore, since the base 21 is made of a flexible or elastic material, the massage head 1 can open the first opening 22 and be received in the first receiving cavity S1. Since the inner diameter of the first receiving cavity S1 is equal to or slightly smaller than the outer diameter of the massage head 1, the massage head 1 can be tightly wrapped.

[0092] See also Fig. 9 , is a schematic diagram viewed from the first side 211 of the substrate 21, as shown Fig. 9 As shown, the edge of the first opening 22 is provided with a convex edge 221 extending toward the inner side of the gel sleeve 2 .

[0093] Therefore, when the massage head 1 is received in the first receiving cavity S1 , one end of the massage head 1 close to the first side 211 can be wrapped and covered by the convex edge 221 , so that the massage head 1 can be more fully wrapped.

[0094] like Fig. 9 As shown, the first opening 22 is further provided with an extension portion 222 extending from the second side 212 to the first side 211. After the massage head 1 provided with the gel sleeve 2 is installed on the neck massager, the extension portion 222 can fit with the surface of the wearing bracket of the neck massager to improve the tightness of the connection.

[0095] The extending direction of the extending portion 222 is perpendicular to the extending direction of the convex edge 221 .

[0096] In some embodiments, the outer surface of the gel sleeve 2 is a smooth curved surface as a whole.

[0097] See also Fig.10, which is a schematic diagram of the base 21 after the conductive gel sheet 3 is contained therein and viewed from the second side 212. The periphery of the outer surface 33 of the conductive gel sheet 3 facing the second side 212 smoothly transitions with the end of the second containing cavity S2 located on the second side, so that the outer surface of the gel sleeve 2 is a smooth curved surface as a whole, which improves the comfort of attaching to the human neck.

[0098] In some embodiments, the outer surface 33 of the conductive gel sheet 3 facing the second side 212 may also be covered with a protective film. The protective film may be made of plastic, resin or other materials, and is used to protect the conductive gel sheet 3 to prevent dust accumulation. When in use, the protective film may be torn off first, so that the conductive gel sheet 3 can directly contact the skin of the human neck.

[0099] Please return to Figure 2 , wherein the massage head 1 may include a support portion 12, an electrode sheet 11 arranged at a first end of the support portion, and a connector 13 arranged at a second end of the support portion 12 opposite to the first end, and the massage head 1 is used to be fixedly connected to the neck massager through the connector 13.

[0100] The connector 13 may be a snap-fitting part, which is fixed to the wearing bracket of the neck massager by snap-fitting with another snap-fitting part of the wearing bracket of the neck massager. The connector 13 may also be a threaded stud, which is fixed to the wearing bracket of the neck massager by cooperating with a threaded opening on the wearing bracket of the neck massager.

[0101] Among them, the aforementioned massage head 1 is accommodated in the first accommodating cavity S1, and the support part 12 and the electrode sheet 11 of the massage head 1 are accommodated in the first accommodating cavity S1, and the connecting member 13 extends from the first opening 22 of the first accommodating cavity S1 and can be fixed on the wearing bracket of the neck massager.

[0102] See also Fig.11 , is a schematic side view of the massage head assembly 100. The massage head assembly 100 can be in the shape of a curved arch bridge as a whole when viewed from the side, and the center of curvature is located at the second side 212, so that when the massage head assembly is attached to the neck of a human body, it can fit well with the periphery of the neck.

[0103] like Fig.11 As shown, the support portion 12, the electrode sheet 11 disposed at the first end of the support portion, and the conductive gel sheet 3 are all in the shape of a curved arch bridge, so that the massage head assembly 100 is in the shape of a curved arch bridge as a whole when viewed from the side.

[0104] Among them, Fig. 9As shown in the figure, from the perspective of the first side 211, the projection of the base 21 in the direction from the first side 211 to the second side 212 is roughly in the shape of an elliptical track. Obviously, the projection of the conductive gel sheet 3, the support portion 12 of the massage head 1, and the electrode sheet 11 in the direction from the first side 211 to the second side 212 is also roughly in the shape of an elliptical track.

[0105] In some embodiments, the base 21 of the gel sleeve 2 is made of a material selected from the group consisting of silicone, rubber, TPE, and TPU.

[0106] Furthermore, the base 21 can be made of conductive silicone material. Thus, the base 21 and the spacer 213 included therein are both made of conductive silicone material, and the conductive gel sheet 3 accommodated in the second accommodation cavity S2 can not only be electrically connected to the electrode sheet 11 of the massage head 1 accommodated in the second accommodation cavity S2 through the through hole K1, etc., but can also be electrically connected to the electrode sheet 11 of the massage head 1 through the spacer 213, thereby increasing the electrical contact area between the conductive gel sheet 3 and the electrode sheet 11 of the massage head 1, and improving the conductive performance. Secondly, the base 21 is made of conductive silicone, and the base 21 itself can also conduct electricity, not just the conductive gel sheet 3; the massage area can be increased.

[0107] Please also read Figure 12-Figure 15 In some embodiments, the gel sleeve 2 further includes a supporting film 25. When the conductive gel sheet 3 is accommodated in the second accommodating cavity S2 and the base 21 is sleeved on the massage head 1, the supporting film 25 is located between the conductive gel sheet 3 and the electrode sheet 11 arranged at the end of the massage head 1, and the supporting film 25 is used to support the conductive gel sheet 3.

[0108] That is, in some embodiments, when the conductive gel sheet 3 is received in the second receiving cavity S2, a portion of the surface 31 of the conductive gel sheet 3 facing the second receiving cavity S2 is attached to the second surface F2 of the sink 214, and another portion of the surface corresponding to the support film 25 is attached to / contacted with the support film 25, so that the sink 214 can be carried on the sink 214 as a carrier, and further supported by the support film 25. Therefore, the stability of the conductive gel sheet 3 received in the second receiving cavity S2 is improved, and the conductive gel sheet 3 is prevented from collapsing into the through hole K1.

[0109] like Figure 13-15As shown, in this embodiment, the support film 25 is arranged on the first surface F1 of the sink 214 facing the first side 211. When the conductive gel sheet 3 is accommodated in the second accommodating cavity S2, the support film 25 contacts the corresponding area of ​​the surface 31 of the conductive gel sheet 3 away from the second side 212 through the through hole K1, thereby supporting the conductive gel sheet 3.

[0110] Among them, Fig.13 As shown, the support film 25 is a long strip-shaped film, which spans across the through hole K1 from one end of the sinking platform 214 and extends to the other end opposite to the sinking platform 214 .

[0111] That is, in this embodiment, the support film 25 is a long strip of film, and both ends of the support film 25 are fixed to the opposite ends of the first surface F1 of the sink 214 on both sides of the through hole K1, and the support film 25 correspondingly crosses the through hole K1. Therefore, when the conductive gel sheet 3 is accommodated in the second receiving cavity S2, the area of ​​the support film 25 crossing the through hole K1 can contact the corresponding area of ​​the conductive gel sheet 3 to support the conductive gel sheet 3.

[0112] The two ends of the support film 25 can be fixed on the first surface F1 of the sink 214 by means of adhesive or the like.

[0113] As mentioned above, the projection of the base 21 from the first side 211 to the second side 212 is roughly in the shape of an elliptical track, and the outer periphery of the sink 214 is also roughly in the shape of an elliptical track. Fig.13 As shown, the strip-shaped support film 25 extends substantially along the long side of the sink 214 , that is, the long side of the support film 25 is substantially parallel to the long side of the sink 214 .

[0114] Among them, Fig.13 As shown, the width of the support film 25 is smaller than the aperture of the through hole K1. The width of the support film 25 refers to the length of the short side of the support film. Therefore, there is a gap between the support film 25 and the edge of the sink 214 surrounding the through hole K1. After the conductive gel sheet 3 is supported by the support film 25, it can also be electrically contacted with the electrode sheet 11 located at the end of the massage head 1 through the gap.

[0115] Please also read Figure 16-Figure 19In the third embodiment, the support film 25 is arranged on the first surface F1 of the sink 214 facing the first side 211, and the support film 25 is also a long strip of film. The two ends of the support film 25 are fixed to the opposite ends of the first surface F1 of the sink 214 on both sides of the through hole K1, and the support film 25 correspondingly crosses the through hole K1. Therefore, when the conductive gel sheet 3 is accommodated in the second accommodation cavity S2, the area of ​​the support film 25 crossing the through hole K1 can contact the corresponding area of ​​the conductive gel sheet 3 to support the conductive gel sheet 3.

[0116] The two ends of the support film 25 can be fixed on the first surface F1 of the sink 214 by means of adhesive or the like.

[0117] The difference from the second embodiment is that in this embodiment, Fig.17 As shown, the strip-shaped support film 25 extends substantially along the short side of the sink 214 , that is, the long side of the support film 25 is substantially parallel to the short side of the sink 214 .

[0118] Similarly, the width of the support film 25 is smaller than the aperture of the through hole K1. Thus, there is a gap between the support film 25 and the edge of the sink 214 surrounding the through hole K1. After the conductive gel sheet 3 is supported by the support film 25, it can also be electrically contacted with the electrode sheet 11 at the end of the massage head 1 through the gap.

[0119] Please also read Figure 20-23 In the fourth embodiment, the support film 25 is disposed on the first surface F1 of the sink 214 facing the first side 211, and the support film 25 is a cross-shaped film, and the projection of the intersection 251 of the cross-shaped film in the direction of the through hole K1 is located inside the through hole K1.

[0120] That is, the four ends of the cross-shaped support film 25 are respectively fixed on the first surface F1 of the sink 214, the two relative terminals of the support film 25 are fixed to the opposite ends of the first surface F1 of the sink 214 along the first direction on both sides of the through hole K1, and the other two relative terminals of the support film 25 are fixed to the opposite ends of the first surface F1 of the sink 214 along the second direction on both sides of the through hole K1.

[0121] The first direction and the second direction are perpendicular. As mentioned above, the projection of the base 21 from the first side 211 to the second side 212 is roughly in the shape of an elliptical track, and the periphery of the sink 214 is also roughly in the shape of an elliptical track. For example, the first direction extends in the direction of the long side of the sink 214, and the second direction extends in the direction of the short side of the sink 214.

[0122] The four ends of the support film 25 can be fixed on the first surface F1 of the sink 214 by means of adhesive or the like.

[0123] Among them, the size of the intersection of the cross-shaped support film 25 is smaller than the size of the through hole K1, and the edges of the support film 25 and the sink 214 surrounding the through hole K1 have a gap. After the conductive gel sheet 3 is supported by the support film 25, it can also electrically contact the electrode sheet 11 located at the end of the massage head 1 through the gap.

[0124] Obviously, in other embodiments, the supporting film 25 may also be a film of other shapes disposed on the first surface F1 of the sink 214 facing the first side 211 for supporting the conductive gel sheet 3, for example, it may also be a grid-shaped, "M"-shaped, etc.

[0125] Please also read Figure 24-Figure 27 In other embodiments, the support film 25 is disposed on the second surface F2 of the sink 214 facing the second side 212. When the conductive gel sheet 3 is accommodated in the second accommodating cavity S2, the support film 25 is located between the second surface F2 of the sink 214 and the conductive gel sheet 3. The support film 25 contacts the corresponding area of ​​the surface 31 of the conductive gel sheet 3 away from the second side 212 to support the conductive gel sheet 3.

[0126] Thus, since the support film 25 and the conductive gel sheet 3 are arranged on the same side of the sinking platform 214, that is, both are arranged on the side of the sinking platform 214 facing the second side 212 of the substrate 21, and when the conductive gel sheet 3 is accommodated in the second accommodating cavity S2, the support film 25 is clamped between the second surface F2 of the sinking platform 214 and the conductive gel sheet 3. Through this arrangement, the support film 25 can be bonded more tightly, thereby enhancing the tension of the support film 25, and then enhancing the support stability of the support film 25.

[0127] That is, in other embodiments, the support film 25 may also be arranged on the second surface F2 of the sink 214 facing the second side 212, and when the conductive gel sheet 3 is accommodated in the second receiving cavity S2, the support film 25 is clamped between the second surface F2 of the sink 214 and the conductive gel sheet 3 to support the conductive gel sheet 3.

[0128] like Fig.25 As shown, in the fifth embodiment, the support film 25 is a long strip-shaped film, which spans across the through hole K1 from one end of the sinking platform 214 and extends to the other end opposite to the sinking platform 214 .

[0129] That is, in this embodiment, the support film 25 is a long strip-shaped film, and the two ends of the support film 25 are fixed to the opposite ends of the second surface F2 of the sink 214 on both sides of the through hole K1, and the support film 25 crosses the through hole K1 accordingly. When the conductive gel sheet 3 is received in the second receiving cavity S2, the support film 25 contacts the corresponding area of ​​the surface 31 of the conductive gel sheet 3 away from the second side 212, and supports the conductive gel sheet 3.

[0130] The two ends of the support film 25 can be fixed on the second surface F2 of the sink 214 by means of adhesive or the like.

[0131] As mentioned above, the projection of the base 21 from the first side 211 to the second side 212 is roughly in the shape of an elliptical track, and the outer periphery of the sink 214 is also roughly in the shape of an elliptical track. Fig.25 As shown, the strip-shaped support film 25 extends substantially along the long side of the sink 214 , that is, the long side of the support film 25 is substantially parallel to the long side of the sink 214 .

[0132] Among them, Fig.25 As shown, the width of the support film 25 is smaller than the aperture of the through hole K1. The width of the support film 25 refers to the length of the short side of the support film. Therefore, there is a gap between the support film 25 and the edge of the sink 214 surrounding the through hole K1. After the conductive gel sheet 3 is supported by the support film 25, it can also be electrically contacted with the electrode sheet 11 located at the end of the massage head 1 through the gap.

[0133] Please also read Figure 28-Figure 31 In the sixth embodiment, the support film 25 is arranged on the second surface F2 of the sink 214 facing the second side 212, and the support film 25 is also a long strip of film. The two ends of the support film 25 are fixed to the opposite ends of the second surface F2 of the sink 214 on both sides of the through hole K1, and the support film 25 correspondingly crosses the through hole K1. Therefore, when the conductive gel sheet 3 is accommodated in the second accommodating cavity S2, the area of ​​the support film 25 crossing the through hole K1 can contact the corresponding area of ​​the conductive gel sheet 3 to support the conductive gel sheet 3.

[0134] The two ends of the support film 25 can be fixed on the second surface F2 of the sink 214 by means of adhesive or the like.

[0135] The difference from the fifth embodiment is that in this embodiment, Fig.29As shown, the strip-shaped support film 25 extends substantially along the short side of the sink 214 , that is, the long side of the support film 25 is substantially parallel to the short side of the sink 214 .

[0136] Similarly, the width of the support film 25 is smaller than the aperture of the through hole K1. Thus, there is a gap between the support film 25 and the edge of the sink 214 surrounding the through hole K1. After the conductive gel sheet 3 is supported by the support film 25, it can also be electrically contacted with the electrode sheet 11 at the end of the massage head 1 through the gap.

[0137] Please also read Figure 32-Figure 35 In the seventh embodiment, the support film 25 is disposed on the second surface F2 of the sink 214 facing the second side 211, and the support film 25 is a cross-shaped film, and the projection of the intersection 251 of the cross-shaped film in the direction of the through hole K1 is located inside the through hole K1.

[0138] That is, the four ends of the cross-shaped support film 25 are respectively fixed on the second surface F2 of the sink 214, the two relative terminals of the support film 25 are fixed to the opposite ends of the second surface F2 of the sink 214 along the first direction on both sides of the through hole K1, and the other two relative terminals of the support film 25 are fixed to the opposite ends of the second surface F2 of the sink 214 along the second direction on both sides of the through hole K1.

[0139] The first direction and the second direction are perpendicular. As mentioned above, the projection of the base 21 from the first side 211 to the second side 212 is roughly in the shape of an elliptical track, and the periphery of the sink 214 is also roughly in the shape of an elliptical track. For example, the first direction extends in the direction of the long side of the sink 214, and the second direction extends in the direction of the short side of the sink 214.

[0140] The four ends of the support film 25 can be fixed on the second surface F2 of the sink 214 by means of adhesive or the like.

[0141] Among them, the size of the intersection of the cross-shaped support film 25 is smaller than the size of the through hole K1, and the edges of the support film 25 and the sink 214 surrounding the through hole K1 have a gap. After the conductive gel sheet 3 is supported by the support film 25, it can also electrically contact the electrode sheet 11 located at the end of the massage head 1 through the gap.

[0142] Obviously, in other embodiments, the supporting film 25 may also be a film of other shapes disposed on the second surface F2 of the sink 214 facing the second side 212 for supporting the conductive gel sheet 3, for example, it may also be a grid-shaped, "M"-shaped, etc.

[0143] In some embodiments, the support film 25 may be a PET (Polyethylene terephthalate) film.

[0144] In some embodiments, the thickness of the support film 25 is 0.06 mm. That is, in the present application, the support film may be a 0.06 mm PET film.

[0145] In other embodiments, the support film 25 may also be a film of other materials, for example, other transparent conductive films, such as ITO (indium tin oxid) film. Thus, the support film 25 can not only support the conductive gel sheet 3, but also realize the electrical connection between the conductive gel sheet 3 and the electrode sheet 11 at the end of the massage head 1, thereby improving the conductive performance. Fig.36 , is a schematic diagram of a neck massager 200 , which may include a massage head assembly 100 and a wearing bracket 300 in any of the aforementioned embodiments, wherein the massage head assembly 100 is mounted and fixed on the wearing bracket 300 .

[0146] Among them, Fig.36 The wearing bracket 300 may be a semi-enclosed ring structure that is roughly in an inverted "U" shape, and can be mounted on the neck of a human body when in use. The massage head assembly 100 is mounted and fixed on the inner side wall 301 of the wearing bracket 300. The inner side wall 301 is the side wall that is directly opposite to the neck of a human body when the wearing bracket 300 is mounted on the neck of a human body.

[0147] The inner wall 301 of the wearing bracket 300 is provided with a connector 302, and the connector 13 of the massage head 1 of the massage head assembly 100 cooperates with the connector 302 on the wearing bracket 300 to fix the massage head assembly 100 on the inner wall 301 of the wearing bracket 300. When the massage head assembly 100 is fixed on the inner wall 301 of the wearing bracket 300, the electrode sheet 11 and the conductive gel sheet 3 of the massage head 1 are located at the end away from the inner wall 301, and when the neck massager 200 is sleeved on the neck of the human body, the conductive gel sheet 3 contacts the skin of the neck of the human body, and a pulse electric stimulation massage of the part of the neck to be massaged can be achieved.

[0148] The connector 302 on the wearing bracket 300 may be a structure such as a snap-fitting part or a threaded opening that matches the connector 13 of the massage head 1 , and may be fixed to the connector 13 of the massage head 1 by snap-fitting or threading.

[0149] The setting position of the connector 302 on the wearing bracket 300 can be set in advance according to the part of the human neck to be massaged, such as the neck acupuncture points. Specifically, it can be predetermined that when the wearing bracket 300 of the neck massager 200 is correctly worn on the human neck, the position directly opposite to the part of the human neck to be massaged is the setting position of the connector 302, and the connector 302 is set at the setting position, so that when the massage head assembly 100 is connected to the connector 302 on the wearing bracket 300 through the connector 13, it will also be fixed at the position. When the wearing bracket 300 of the neck massager 200 is correctly worn on the human neck, the positions of the electrode sheet 11 of the massage head assembly 100 and the conductive gel sheet 3 will be directly opposite to the part of the human neck to be massaged, and the part to be massaged can be subjected to pulse electrical stimulation massage.

[0150] The neck massager 200 may include a plurality of massage head assemblies 100, each corresponding to a part of the human neck to be massaged. After each massage head assembly 100 is disposed on the wearing bracket 300, it extends radially inwardly of the wearing bracket 300, that is, extends in a direction away from the inner side wall 301 of the wearing bracket 300.

[0151] Thus, the neck massager 200, massage head assembly and gel sleeve provided by the present invention are provided with a gel sleeve 2 on the massage head 1, and the gel sleeve 2 can further accommodate a conductive gel sheet 3 for electrically connecting to the electrode sheet on the massage head 1, and contact with human skin is achieved through the conductive gel sheet 3. The conductive gel sheet 3 can be filled into the gaps in the squamous stratum corneum, so that the electrode sheet on the massage head 1 is in electrical contact with the dermis layer under the stratum corneum of the human body, so that the electrode sheet can be fully electrically connected with the dermis layer of the human skin at the part to which the massage head 1 is attached, thereby increasing the electrical conduction effect area, reducing local energy concentration, avoiding tingling during use, and greatly improving the user experience.

[0152] The neck massager disclosed in the embodiment of the present invention is introduced in detail above. Specific examples are used in this article to illustrate the principle and implementation mode of the present invention. The description of the above embodiment is only used to help understand the neck massager of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
