As shown in fig. 1 and 2, the cervical vertebrae massager 10 of an embodiment includes a massager body 100 and an expansion assembly 200. In one embodiment, the expansion element 200 is elastically connected to the main body 100, so that the expansion element 200 can elastically support against the neck of the user. Referring also to fig. 3, the extension member 200 is formed with an electrode pad layer 205, and when the user wears the cervical vertebrae massager 10, the electrode pad layer 205 is closely attached to the neck of the user.

As shown in fig. 2 and 3, in one embodiment, the expansion assembly 200 is connected to the massager body 100, and the expansion assembly 200 includes an expansion piece 210, an elastic member 220 and a connecting head 230. The electrode sheet layer 205 is formed on one surface of the extending sheet 210. The elastic member 220 is connected to the expansion tab 210. The connection head 230 is connected to the elastic member 220 such that the connection head 230 is connected to the expansion piece through the elastic member 220. The elastic piece is used for having the elastic deformation in the predetermined angle range when using for the extension piece swings in the predetermined angle range. The expansion piece swings within a preset angle range through the elastic member 220, so that the expansion piece 210 swings within a preset angle range relative to the connecting head 230, and thus the expansion piece 210 is elastically attached to the neck of the human body. In this embodiment, when the cervical vertebra massager is worn and used, the elastic member 220 has an elastic deformation within a preset angle range, so that the expansion piece 210 swings within the preset angle range through the elastic member 220. The connection head 230 is also connected to the massage apparatus main body 100 such that the extension pieces are connected to the massage apparatus main body 100 through the elastic members 220 and the connection head 230, respectively, thereby elastically connecting the extension pieces to the massage apparatus main body 100.

The extension assembly 200 and the cervical vertebra massager 10, the connector 230 is connected with the massager body 100, because the elastic member 220 is connected with the extension sheet 210, the connector 230 is connected with the elastic member 220, so that the extension sheet 210 is connected with the connector 230 through the elastic member 220, thereby elastically connecting the extension sheet 210 to the massager body 100, in addition, when the cervical vertebra massager is worn and used, the elastic member 220 has elastic deformation within a preset angle range, so that the extension sheet 210 swings within the preset angle range through the elastic member 220, and the extension sheet 210 swings within the preset angle range relative to the connector 230, thereby elastically attaching the extension sheet 210 to the neck of a human body. When the massage device is worn, the neck of a user is abutted and pressed on the expansion piece 210, and due to the fact that the elastic part has elastic deformation within a preset angle range when the expansion piece is used, the expansion piece swings within the preset angle range relative to the massage device body, namely the expansion piece swings within the preset angle range through the elastic part, the expansion piece is pressed to drive the elastic part to bend within the preset angle range, so that the expansion piece 210 elastically deforms through the elastic part 220 and provides abutting force for the neck of the user, the neck of the user can be tightly attached to the expansion piece 210, and the problem that the expansion piece is easily separated from the skin of the neck is solved. In design, the electrode pad 205 may be disposed on the surface of the extension piece 210 that is in close contact with the neck of the user, so that the electrode pad 205 is in close contact with the neck of the user, and the electrode pad 205 can massage the neck of the user better.

As shown in fig. 1 and 2, in one embodiment, the massage apparatus body 100 has an arc shape, and an arc-shaped slot 110 is formed in the massage apparatus body 100. The connector 230 is connected to one side of the main body 100. In this embodiment, the main body of the massage apparatus is bent in a direction, a plane on which the main body of the massage apparatus is bent is set to be a radial plane of the main body of the massage apparatus, and a direction perpendicular to the radial plane of the main body of the massage apparatus is set to be an axial direction of the main body of the massage apparatus. The massager body is provided with a first side surface and a second side surface, and the first side surface and the second side surface are parallel to the radial plane. The connection head 230 is connected to a first side surface of the massager body 100. In a natural state, the extension pieces 210 face the arc-shaped groove 110 defined by the massager body 100, that is, the extension pieces are disposed toward the radial plane of the massager body, and the electrode pieces 205 are disposed toward the arc-shaped groove 110 defined by the massager body 100. When a user wears the massager, the neck of the user abuts against the expansion sheet 210, the expansion sheet drives the elastic member to bend towards the direction away from the arc-shaped groove 110 surrounded by the massager main body 100, namely the expansion sheet bends towards the direction away from the radial plane of the massager main body, and the expansion sheet 210 elastically deforms through the elastic member 220 and provides an abutting force for the neck of the user, so that the electrode sheet 205 is tightly attached to the neck of the user.

The extending direction of the end of the elastic member 220 adjacent to the expansion piece 210 and the extending direction of the end of the elastic member 220 away from the expansion piece 210 form an angle, i.e. the elastic member is bent. Because one end of the elastic element 220 extends to the expansion sheet 210 and is connected with the expansion sheet 210, the other end of the elastic element 220 extends to the connecting head 230 and is connected with the connecting head 230, and the two ends of the elastic element 220 are respectively connected with the expansion sheet 210 and the connecting head 230, so that the expansion sheet 210 is in better elastic abutting contact with the neck of a user, when the expansion piece is worn, the neck of the user abuts against the expansion sheet 210, the expansion sheet 210 elastically deforms through the elastic element 220 and provides abutting force for the neck of the user, the expansion sheet 210 can reliably cling to the neck of the user, and the problem that the fitting performance of the expansion sheet 210 and the neck of the user is poor is solved. In design, the electrode pad 205 may be disposed on the surface of the extension piece 210 that is in close contact with the neck of the user, so that the electrode pad 205 can better massage the neck of the user.
