The invention provides a cervical vertebra massager.

Referring to fig. 1 to 3, in the preferred embodiment of the cervical vertebra massager of the present invention, the cervical vertebra massager 10 includes an elastic member 11, an electrode assembly 12, a flexible member 13, an insert 14, an electric pulse generating device 15 and two handles 16. The electric pulse generating device 15 is electrically connected to the electrode assembly 12. The electrode assembly 12 is disposed on the elastic member 11 through the flexible member 13 and the insert 14, and the electrode assembly 12 is adjusted in a floating manner by deformation of the flexible member 13. The handle 16 is fixedly connected to both ends of the elastic member 11, and the wearing grip is realized by the deformation of the elastic member 11.

It should be noted that the flexible element 13 is less rigid than the insert 14, and after being injection molded into a certain shape, it will deform under the action of external force to generate resilience, and will recover to its original shape once the external force is removed. The flexible member 13 may be made of silicone rubber.

The insert 14 includes a base 141 and hooks 142 disposed on the base 141, and the insert 14 is integrally injection-molded with the flexible member 13 at the base 141. The insert 14 has a stiffness greater than that of the flexible member 13. The elastic member 11 is provided with a plurality of slots 111 along the direction of the elastic member 11. The hooks 142 are held in the corresponding slots 111, and pull the flexible element 13 to be disposed along the direction of the elastic element 11, and the flexible element 13 generates a deformation resilience force with the base 141 of the insert 14 as a fulcrum when being stressed.

Compared with the background art, the cervical vertebra massager 10 of the present invention can better ensure the floating adjustment performance of the electrode assembly 12, and the specific reasons are as follows: since the hardness of the insert 14 is greater than that of the flexible element 13, and the insert 14 is integrally injection-molded with the flexible element 13 at the base 141, the relative connection positions of the insert 14 and the flexible element 13 are integrally cured, and the insert 14 is uniform and reliable, when the flexible element 13 deforms, the insert 14 will be spontaneously supported by the base 141 of the insert 14, in other words, the actual supporting point position of the deformation of the flexible element 13 is determined by the insert 14, and the mounting position of the insert 14 itself is determined by the mutual engagement of the hooks 142 and the slots 111, it is known that the engagement and mounting manner of the hooks 142 and the slots 111 is more stable and reliable than the adhesion manner mentioned in the background art, so that the insert 14 can be well mounted in place during the actual production process, thereby ensuring the actual supporting point position of the deformation of the flexible element 13, and further, the resilience generated when the flexible member 13 is deformed is ensured, so that the floating adjustment performance of the electrode assembly 12 is reliably ensured.

In order to better ensure the stable holding of the insert 14, the elastic member 11 includes a first end 112 and a second end 113 opposite to the first end 112, and a portion of the hooks 142 faces the first end 112 of the elastic member 11 and a portion faces the second end 113 of the elastic member 11. When the insert 14 is used, the insert 14 is prevented from falling off the elastic member 11 during repeated expansion and contraction of the elastic member 11, for example, the elastic member 11 tends to be straightened and deformed when being expanded to two sides, so that the design of hooks with incompletely consistent orientation can avoid the situation that all the hooks 142 are about to fall off, in other words, at least part of the hooks 142 are in a stable clamping state, thereby ensuring the stable clamping of the insert 14. Specifically, the cervical vertebra massager 10 further includes an axis, the first end 112 and the second end 113 of the elastic member 11 are symmetrical with respect to the axis, the hooks 142 of the plurality of hooks 142 close to the axis are disposed in a direction away from the axis, and the hooks 142 far away from the axis are disposed in a direction toward the axis. When the elastic member 11 is expanded towards two sides, the hook 142 far from the axis has a relatively obvious tendency to move towards the axis relative to the corresponding slot 111, so that the hook 142 can be forced to be hooked on the slot wall of the slot 111 close to the axis more stably.

Furthermore, the width of the locking slot 111 along the direction of the elastic element 11 is equivalent to the width of the corresponding hook 142. So that the hook 142 is less likely to be separated from the card slot 111.

As for the material selection of the insert 14, the following schemes can be specifically adopted in this embodiment, but not limited to:

first, the insert 14 is an elastic member, which generates a resilient force along with the deformation of the elastic member 11, in this embodiment, the insert 14 can enhance the resilient performance of the elastic member 11, specifically, the insert can be a steel strip, and the elastic member 11 can be a plastic strip.

Secondly, the insert 14 is a plastic member which can be bent into various shapes at will without spontaneous springback, and the insert 14 of this solution is not resilient and thus saves more time and labor during assembly.

In particular production, the way in which the flexible element 13 and the insert 14 are injection-molded as a single piece in the present invention can take, but is not limited to, the following two specific forms:

first, the flexible member 13 and the insert 14 are injection molded into a flat shape, the insert 14 is assembled to the elastic member 11 and then changes from the flat shape to a shape which is identical to the shape of the elastic member 11, the flat flexible member 13 and the insert 14 have lower requirements for the structure of the mold, and the finished product is easier to transport and package.

Secondly, as shown in fig. 3, the flexible element 13 and the insert 14 are injection molded into an arc shape, and have a shape corresponding to the shape of the elastic element 11, and the flexible element 13 and the insert 14 of this embodiment are matched with the elastic element 11, so as to facilitate the alignment installation of the hook 142 and the slot 111. This embodiment adopts such a scheme.

In order to firmly fix the insert 14, the elastic element 11 is provided with a groove 114, and the base 141 of the insert 14 is sunk into the groove 114. By sinking the insert 14 into the groove 114, the base 141 can be limited by the wall of the groove 114, which on the one hand prevents the hook 142 from being pulled off by direct force and on the other hand is more attractive.

Referring to fig. 3 and 4, in order to maximize the adjustment space, the elastic member 11 of the present invention includes two convex edges 115 and a cavity 116 located between the two convex edges 115, the two convex edges 115 are disposed at two sides of the elastic member 11, the elastic member 11 is respectively provided with a groove 114 at each convex edge 115, the bottom of each groove 114 is provided with the locking slot 111, and the locking hook 142 is locked in the locking slot 111 when the insert 14 is inserted into the groove 114. In the present embodiment, the present invention includes two inserts 14, each insert 14 is a strip-shaped body, and the hook 141 of each insert 14 passes through the slot 111 of the corresponding groove 114 and finally locates in the cavity 116. Since the inserts 14 are elongated bodies rather than wide plates, i.e., they do not occupy too much space in the cavity 116, this provides as much space as possible for the deformation of the flexible member 13, and thus the adjustable spatial extent of the electrode assembly 12 is also greater.

Referring to fig. 2 again, for reinforcement, the weak point of the elastic element 11 in the slot wall of the slot 111 is further provided with a reinforcing rib 117.

Referring to fig. 4 again, in the present embodiment, the specific structure of the flexible element 13 includes a body 131 and a hollow flexible base 132, the body 131 and the flexible base 132 are integrally formed, the electrode assembly 12 is disposed on the flexible base 132, and the thickness of the connection portion between the flexible base 132 and the body 131 is thinner than the thickness of other portions of the body 131. Such that the flexible base 132 tends to deform uniformly at the joint when the electrode assembly 12 is swung for adjustment, so that adjustment of the electrode assembly 12 is smoother.

The cervical massager 10 further comprises a rigid mounting seat 17, the rigid mounting seat 17 is disposed at the free end of the flexible base 132, and the electrode assembly 12 is fixed to the rigid mounting seat 17. Such a way makes the free end of the flexible base 132 stronger than the joint where the flexible base 132 is more easily subjected to swing adjustment when the electrode assembly 12 swings. In addition, the addition of the rigid mounting 17 also facilitates the mounting of the electrode assembly 12.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
