In addition, the first elastic element 51 can assist in centering the second elastic element 52, and can prevent the second elastic element 52 from being skewed when being reset, so that the stability of the whole elastic element 5 is ensured.

In addition, it should be added that, in the present embodiment, the elastic member 5 includes a first elastic member 51 and a second elastic member 52 that are connected to each other and sleeved together, and in other embodiments, there may be more than two elastic members 5, or three or more elastic members that are connected to each other and sleeved together, so that the overall stability of the elastic members is better. Specifically, the number of the elastic members is set according to actual needs, and this embodiment does not specifically limit this.

It should be added that the first elastic element 51 and the second elastic element 52 may be springs, and the springs should be always in a compressed state, so that the springs may have a compressive deformation force in the compressed state for pushing the connecting rod 3 abutting against them to move circumferentially and/or axially relative to the fixing element 2. Specifically, the length, the elastic modulus, and the initial compressibility of the spring are determined according to the actual requirement of the amount of movement of the massage head assembly 4 to achieve the axial and/or circumferential movement, which is not specifically limited in this embodiment.

Further, in this embodiment, a space is provided between the second elastic member 52 and the inner wall of the connecting rod 3, so that the second elastic member 52 does not interfere with the inner wall of the connecting rod 3 in the process of resetting or deforming, and the deformation and resetting of the second elastic member 52 are affected, thereby ensuring the sliding or rotating stroke of the connecting rod 3 abutted against the second elastic member 52, and further ensuring the moving stroke of the massage head assembly 4 connected to the connecting rod 3.

Specifically, in the present embodiment, the interval is greater than 1.5mm, for example, the interval between the second elastic element 52 and the inner wall of the connecting rod 3 may be 2mm or 3mm, and the size of the interval may also be set according to actual needs, which is not specifically limited in the present embodiment.

As shown in fig. 3d, in the embodiment of the present embodiment, the first elastic member 51 is cylindrical, the second elastic member 52 is tower-shaped, and the diameter of the tower-shaped second elastic member 52 is greater than the outer diameter of the circular first elastic member 51, so that the tower-shaped second elastic member 52 is located outside the cylindrical first elastic member 51, and thus after the first elastic member 51 is positioned, the first elastic member 51 can perform an auxiliary positioning function on the second elastic member 52, and prevent the second elastic member 52 from tilting due to resetting, which affects smooth resetting of the second elastic member 52.

In other embodiments of the present embodiment, the first elastic element 51 is square, the second elastic element 52 is prism-shaped, and the diameter of the prism-shaped second elastic element 52 is greater than the outer diameter of the square-shaped first elastic element 51, so that the prism-shaped second elastic element 52 is located outside the square-shaped first elastic element 51, and thus after the first elastic element 51 is positioned, the first elastic element 51 can play an auxiliary positioning role for the second elastic element 52, and the second elastic element 52 is prevented from being reset and inclined, which affects smooth resetting of the second elastic element 52.

In addition, the shapes of the first elastic element 51 and the second elastic element 52 may not be limited to the above examples of the embodiment, and may be set to other shapes according to actual needs, which is not specifically limited in the embodiment.

As shown in fig. 3c and 3D, when the second elastic member 52 is of a tower shape, the radial dimension of the second elastic member 52 is D, D is greater than or equal to 2mm and less than or equal to 3mm, so that the flexibility of the second elastic member 52 can be satisfied, that is, the rigidity of the second elastic member 52 is not too high, so that the second elastic member 52 has a certain sensitivity, that is, the second elastic member 52 can be smoothly twisted in the axial direction or the circumferential direction of the connecting rod 3, so as to ensure the motion flexibility of the connecting rod 3 connected therewith, thereby indirectly ensuring that the connecting rod 3 drives the massage head assembly 4 to flexibly move, so that the massage head assembly 4 can more flexibly move or rotate to fit the neck of the human body. Specifically, the radial dimension of the second elastic element 52 may be 2mm, may also be 3mm, and may also be any dimension between 2mm and 3mm, which is specifically set according to actual needs, and this embodiment does not specifically limit this.

As shown in fig. 3b, 3c, and 3d, the density of the first and second elastic members 51 and 52 gradually decreases from both ends to the middle in the axial direction (i.e., the vertical direction in fig. 3 b) of the first and second elastic members 51 and 52.

In an embodiment of the present embodiment, the first elastic member 51 and the second elastic member 52 may be springs, and the decreased density means that the spring coils at the upper and lower ends are more dense and the spring coil in the middle is more loose, so that the elastic member 5 can be stably installed. Specifically, the two ends of the first elastic member 51 and the second elastic member 52 are used for abutting against the first housing 11 or the connecting rod 3, and the spring coils at the two ends of the first elastic member 51 and the second elastic member 52 are arranged densely, so that the rigidity is high, the elasticity is poor, and the deformation is not easy to occur, thereby reducing the interference between the two ends of the first elastic member and the first housing 11 or the connecting rod 3 to a certain extent. The spring coils of the first elastic element 51 and the second elastic element 52 located in the middle are loose, so that the elasticity of the middle position of the spring coils is strong, the rigidity is not too high, and the sensitivity of the spring coils can be improved, i.e. the first elastic element 51 and the second elastic element 52 can be smoothly twisted in the axial direction or the circumferential direction of the connecting rod 3.

In other embodiments of the present embodiment, the first elastic element 51 and the second elastic element 52 may also be other members that are bendable and have elastic deformation capability.

In this embodiment, as shown in fig. 6, a position on the inner wall of the first housing 11 corresponding to the first elastic element 51 extends toward the fixing element 2 to form the positioning portion 13, the first elastic element 51 is sleeved on the outer peripheral wall of the positioning portion 13, so as to play a role in positioning the first elastic element 51, so that the first elastic element 51 can be smoothly reset, and meanwhile, the second elastic element 52 connected with the first elastic element 51 can be indirectly assisted to be positioned, thereby preventing the resetting from being skewed, and ensuring the stability of the elastic element 5.

In order to make the first elastic element 52 sleeved on the periphery of the positioning portion 13 and not easy to separate from the positioning portion 13 in the process of resetting or deformation, in this embodiment, the extending length of the positioning portion 13 is greater than 4mm in the extending direction from the first housing 11 to the fixing element 2, so as to ensure that the overlap ratio between the first elastic element 51 and the positioning portion 13 is high enough to prevent the first elastic element 51 from falling off, and ensure the positioning reliability. Specifically, the extension length of the positioning portion 13 may be 4.5mm, that is, the length of the overlapped portion between the first elastic member 51 and the positioning portion 13 may be 4.5mm, the extension length of the positioning portion 13 may also be 5mm, and the like.

In this embodiment, as shown in fig. 6, the positioning portion 13 is a cross positioning portion, the cross positioning portion is an axisymmetric structure or a centrosymmetric structure, and has 4 edges 131 symmetrically arranged, the first elastic member 51 is sleeved on the peripheries of the 4 edges 131, so that the stability of sleeving between the first elastic member 51 and the positioning portion 13 can be improved, and the cross positioning portion is a symmetric structure, so that self-help centering of the first elastic member 51 can be further ensured. In other embodiments, the positioning portion 13 may also be a cylindrical structure or a prismatic structure, which is specifically set according to actual needs, and this embodiment does not specifically limit this.

Further, as for the connection mode between the fixing element 2 and the first housing 11, referring to fig. 2a, fig. 2b, and fig. 2c, in this embodiment, the outer periphery of the fixing element 2 extends outward to form a mounting portion 22, a clamping portion 111 is formed on the inner wall surface of the first housing 11 at a position corresponding to the mounting portion 22, and the fixing element 2 and the first housing 11 are relatively fixed by the matching clamping of the mounting portion 22 and the clamping portion 111, so that the connection between the fixing element 2 and the first housing 11 is more reliable, and the falling off is prevented.

In the embodiment of the present embodiment, the mounting portion 22 may be a mounting post or a mounting boss formed to protrude outward from the outer peripheral wall of the fixing member 2. The joint portion comprises two teeth that set up relatively, and the joint between mounting column or installation boss stretch into the space that two teeth formed in order to realize mounting 2 and first casing 11 to make the connection between mounting 2 and the first casing 11 more reliable, prevent to take place to drop.

It should be added that the mounting post or the mounting boss is a cylindrical member extending outward along the outer peripheral wall of the fixing member 2, and the specific cross-sectional shape of the cylindrical member may be a rectangle, a diamond, or any other shape, which is specifically selected according to actual needs, and this embodiment does not limit this.

It should be noted that, as shown in fig. 2b, a gap is formed between the two teeth that are oppositely arranged, and in order to avoid the problem that the mounting portion 22 is easy to fall off from the gap when extending into the space formed by the two teeth, which results in the failure of the relatively fixed connection between the fixing member 2 and the first housing 11, the gap may be set to be smaller than the maximum size of the mounting portion 22, so as to lock the mounting portion 22 and avoid the mounting portion 22 falling off from the gap.

Specifically, the size of the gap and the size difference between the gap and the maximum size of the mounting portion 22 are set according to actual needs, and this embodiment is not particularly limited thereto.

In other embodiments of the present embodiment, the mounting portion 22 may also be a hook, and the clamping portion 111 may specifically be a clasp, and the hook is hung on the clasp, so that the fixed member 2 and the first housing 11 can also be fixedly connected relatively.

It should be noted that, for the relative fixed connection between the fixing member 2 and the first housing 11, reference may be made to the above two examples of the present embodiment, but it should not be limited that the fixing member 2 and the first housing 11 may be connected only by the above two ways, and other similar schemes should be considered as falling within the protection scope of the present embodiment.

Further, in this embodiment, each tooth is formed with a guiding inclined plane 112, so that the guiding inclined planes 112 of the two oppositely arranged teeth jointly form an opening 113 for guiding the installation part 22, thereby facilitating the connection and assembly between the installation part 22 and the clamping part 111 and improving the installation efficiency.

Further, in this embodiment, referring to fig. 3a and 3b, a socket 23 is disposed at one end of the fixing member 2 away from the first housing 11 (that is, the socket 23 is disposed at the bottom end of the fixing member in fig. 3 b), the connecting rod 3 includes a first connecting rod 31 and a second connecting rod 32, one end of the first connecting rod 31 is connected to the massage head assembly 4, and the other end of the first connecting rod forms the second connecting rod 32 in a direction away from the massage head assembly 4, and the second connecting rod 32 is located in the cavity 21 of the fixing member 2, so that the second connecting rod 32 can move axially or rotate axially relative to the inner wall of the fixing member 2, so as to drive the massage head assembly 4 connected to one end of the first connecting rod 31 to move axially and/or circumferentially along the second connecting rod 32 or the first connecting rod 31, so as to better fit the neck of the human body, and thus the massage effect is better.

In addition, it should be explained that, since the second connecting rod 32 is located in the inner cavity 21 of the fixing member 2 for circumferential or axial movement relative to the inner cavity of the fixing member 2, the second connecting rod 32 is located in the inner cavity 21 of the fixing member 2, and one end of the first connecting rod 31 is connected with the massage head assembly 4, so that the first connecting rod 31 is located at least partially outside the fixing member 2 to be connected with the massage head assembly 4 without interference, and therefore, the first connecting rod 31 can extend from the socket 23 to the outside of the fixing member 2.

In order to satisfy the above situation, the outer diameter of the second section of connecting rod 32 is greater than the outer diameter of the first section of connecting rod 31, and the outer diameter of the first section of connecting rod 31 is less than or equal to the inner diameter of the socket 23, so that the second section of connecting rod 32 extends into the fixing member 2 and the first section of connecting rod 31 partially protrudes out of the socket 23, specifically, the outer diameter of the first section of connecting rod 31, the outer diameter of the second section of connecting rod 32, the caliber size of the socket 23 and the size difference between the first section of connecting rod 31 and the second section of connecting rod are set according to actual requirements, as long as the second section of connecting rod 32 can be located in the inner cavity 21 of the fixing member 2 so as not to slide out of the socket 23, and the part of the first section of connecting rod 31 can protrude out of the fixing member 2 from the socket 23, which is not specifically limited in this embodiment.

It can be added that the first connecting rod 31 and the second connecting rod 32 can be integrally formed, so as to save the processing procedure and improve the production efficiency.

Further, in this embodiment, as shown in fig. 3b, one end of the first section of connecting rod 31 far away from the massage head assembly 4 (i.e. the upper end of the first end connecting rod in fig. 3 b) extends into the inside of the second section of connecting rod 32 to form a boss 311, a clamping groove 312 is formed between the outer side wall of the boss 311 and the inner side wall of the second section of connecting rod 32, one end of the second elastic member 52 close to the massage head assembly 4 is clamped in the clamping groove 312, so as to play a positioning role for the second elastic member 52, and prevent the problem that the one end of the second elastic member 52 close to the massage head assembly 4 is unreliable due to the fact that there is no limiting device to abut against the connecting rod 3.

It should be added that the size of the snap groove 312 may be specifically determined according to the size of the second elastic member 52, and this embodiment is not particularly limited thereto.

In this embodiment, as for the formation manner of the clamping groove 312, the wall thickness of the second section of connecting rod 32 may gradually decrease along the direction toward the first housing 11; and the wall thickness of the first section connecting rod 31 forming the boss 311 is gradually reduced along the direction towards the first casing 11, so that the part of the first section connecting rod 31 extending into the second section connecting rod 32 has a gap between the second section connecting rod 32, that is, the clamping groove 312 described herein is formed, thereby preventing the massage head component 4 from interfering with the second elastic member 5 when moving circumferentially, and improving the use reliability.

Further, in this embodiment, referring to fig. 3a and 3b, the radial dimension (i.e., the dimension in the left-right direction) of the second-stage connecting rod 32 is gradually increased along the direction approaching the first housing 11, so that the outer surface of the second-stage connecting rod 32 is convex, the inner wall surface of the fixing member 2 contacting the second-stage connecting rod 32 is concave adapted to the convex surface, because the inner wall surface of the fixing member 2 contacting the second-stage connecting rod 32 is concave adapted to the convex outer surface of the second-stage connecting rod 32, and the concave-convex surfaces are matched to play a guiding role, so that the fixing member 2 and the second-stage connecting rod 32 are automatically centered through the concave-convex surface matching, which is beneficial for the second-stage connecting rod 32 to return to the initial position when being reset, so as to improve the repeatability of the movement of the massage head assembly 4.

Moreover, it should be added that the fixing member 2 and the second section of connecting rod 32 are matched through the spherical surface, and can also be used for providing a rotating space for the second section of connecting rod 32 to rotate relative to the circumferential direction of the fixing member 2, so as to improve the degree of freedom of the circumferential rotation of the first section of connecting rod 31 connected with the second section of connecting rod 32, so that the circumferential rotation of the massage head assembly 4 connected with the first section of connecting rod 31 is more free and smooth, thereby better fitting the neck of the human body, and better massaging effect. The convex outer surface of the second-stage connecting rod 32 of the present embodiment can be understood as a partial spherical surface as shown in fig. 3 b.

Further, in this embodiment, referring to fig. 3a and 3b, as mentioned above, the second section of connecting rod 32 needs to move along the axial direction thereof in the cavity 21 of the fixing member 2 to enable the massage head assembly 4 to move along the axial direction of the second section of connecting rod 32, therefore, in order to satisfy the above working process, a plurality of first sliding portions 321 are disposed on the outer circumferential wall of the second section of connecting rod 32 at intervals along the circumferential direction thereof, and a plurality of second sliding portions 24 are formed on the inner wall of the fixing member 2 at positions corresponding to the first sliding portions 321, so that the second section of connecting rod 32 and the fixing member 2 can be slidably connected through the sliding fit of the first sliding portions 321 and the second sliding portions 24, thereby enabling the second section of connecting rod 32 to move along the axial direction and/or the circumferential direction thereof in the fixing member 2.

In the implementation manner of the present embodiment, one of the first sliding portion 321 and the second sliding portion 24 is a protrusion, and the other is a sliding groove, so that the second connecting rod 32 and the fixing member 2 can be slidably connected through the sliding fit of the protrusion and the sliding groove.

For example, referring to fig. 3a, a plurality of protrusions are formed on the outer circumferential wall of the second connecting rod 32 at intervals along the circumferential direction thereof as first sliding portions 321, and a plurality of sliding grooves are formed on the inner wall of the fixing member 2 at positions corresponding to the protrusions as second sliding portions 24, so that the second connecting rod 32 and the fixing member 2 can be slidably connected through sliding engagement of the protrusions and the sliding grooves, and the second connecting rod 32 can move in the fixing member 2 along the axial direction thereof.

Alternatively, in other embodiments, the following may be used: a plurality of sliding grooves are formed in the peripheral wall of the second section of connecting rod 32 at intervals along the circumferential direction of the second section of connecting rod, and a plurality of protrusions are formed on the inner wall of the fixing part 2 at positions corresponding to the sliding grooves, so that the second section of connecting rod 32 and the fixing part 2 can be slidably connected through the sliding fit of the protrusions and the sliding grooves, and the second section of connecting rod 32 can move in the fixing part 2 along the axial direction of the fixing part.

In other implementation manners of the present embodiment, one of the first sliding portion 321 and the second sliding portion 24 is a rolling ball, and the other is a sliding rail, so that the second connecting rod 32 and the fixing member 2 can be slidably connected through sliding engagement of the rolling ball and the sliding rail.

For the sliding connection manner between the second connecting rod 32 and the fixing part 2, reference may be made to the above example of the present embodiment, but it should not be limited that the sliding connection manner between the second connecting rod 32 and the fixing part 2 can be implemented only by the above example, and other similar alternatives should also belong to the protection scope of the present embodiment.

Further, in this embodiment, a gap is preset between the outer peripheral wall of the first connecting rod 31 and the socket 23 to prevent the first connecting rod 31 from interfering with the inner wall of the socket 23 of the fixing member 2 during circumferential rotation, which affects the reliability and continuity of circumferential rotation, and further affects the circumferential movement of the massage head assembly 4 to better fit the neck of the human body.

Specifically, the gap may be set to be greater than 1mm, for example, the gap may be specifically 2mm, may also be 2.5mm, and may also be other gap values, which is specifically set according to actual needs, and this embodiment does not specifically limit this.
