The technical solution of the present application will be further described with reference to the following embodiments and accompanying drawings.

Referring to fig. 1, 2a, 2b, 2c, 3a, the present application discloses a neck massager 10 comprising: the middle bracket 1 is provided with a fixing piece 2 with a cavity 21, and the fixing piece 2 is fixedly connected to the inner wall of the middle bracket 1; at least one part of the connecting rod 3 extends into the cavity 21, one end of the connecting rod 3 far away from the cavity 21 is connected with a massage head component 4, and the connecting rod 3 can drive the massage head component 4 to move along the axial direction and/or the circumferential direction of the connecting rod 3; and the elastic part 5 is in a compressed state, one end of the elastic part 5 is abutted on the inner wall of the middle support 1, and the other end of the elastic part 5 is abutted on the connecting rod 3, so that the connecting rod 3 is kept at a certain position or reset under the compression elastic force of the elastic part 5, and the universal floating of the massage head component 4 is realized, so that the massage head component 4 is more attached to the neck of a human body, and the massage effect is better.

In this embodiment, the specific implementation manner is as follows: the middle support 1 comprises a first shell 11 and a second shell 12 which are connected with each other, wherein the first shell 11 is a shell on the side far away from the user, that is, the first shell 11 is an outer shell, and the second shell 12 is a shell on the side close to the user, that is, the second shell 12 is an inner shell. The fixing member 2 is fixed on the inner wall of the first housing 11, and one end of the elastic member 5 abuts on the inner wall of the first housing 11. The first housing 11 and the second housing 12 may be fixedly connected by a snap connection, an adhesive connection, or the like, so that the first housing 11 and the second housing 12 are connected to form a complete housing structure with a smooth transition at the connection. It can be stated that the intermediate support 1 formed by the first shell 11 and the second shell 12 can have elasticity to adapt to users with different neck circumferences, and it can be made of a material with elasticity, and the specific material is selected according to actual needs, and this embodiment is not specifically exemplified.

In this embodiment, the elastic member 5 may be located in the fixing member 2 and the connecting rod 3, one end of the elastic member 5 abuts on the inner wall of the first housing 11, the other end abuts on the connecting rod 3, and the elastic member 5 is always in a compressed state, so that the elastic member 5 has a certain deformation between the two, the elastic member 5 can be compressed and deformed to generate a deformation force, and the connecting rod 3 abutting on the elastic member 5 can be pushed to be kept at a certain position or reset when moving along the axial direction and/or the circumferential direction of the connecting rod 3, so that the massage head assembly 4 can better contact with the skin of the human body.

Meanwhile, at least one part of the connecting rod 3 can extend into the cavity 21 of the fixing part 2, so that relative circumferential and/or axial movement can be generated between the connecting rod 3 and the cavity 21, namely, one end of the connecting rod 3 extending into the cavity 21 can rotate circumferentially or move axially relative to the inner wall of the fixing part 2, and therefore the connecting rod 3 can be linked with the massage head component 4 to move circumferentially and/or axially along the connecting rod 3, so that the massage head component 4 can move to a position attached to the skin of a human body.

In summary, in the embodiment, by providing the fixing member 2, the connecting rod 3 and the elastic member 5, one end of the connecting rod 3 away from the cavity 21 is connected with the massage head assembly 4, so that the massage head assembly 4 connected with the other end of the connecting rod 3 can be driven to move axially when the connecting rod 3 moves axially along the connecting rod 3; and at least one part of the connecting rod 3 can extend into the cavity 21 of the fixing part 2, so that relative circumferential motion can be generated between the connecting rod 3 and the cavity 21, namely, one end of the connecting rod 3 extending into the cavity 21 can move circumferentially relative to the inner wall of the fixing part 2, and the linked massage head assembly 4 of the connecting rod 3 can move circumferentially along the connecting rod 3. Therefore, the connecting rod 3 can link the massage head component 4 along the axial and/or circumferential motion of the connecting rod 3, and, one end butt of the elastic component 5 is on the inner wall of the middle support 1, the other end butt of the elastic component 5 is on the connecting rod 3, the elastic component 5 can compress to deform so as to generate deformation force, so that the connecting rod 3 can be kept at a certain position or reset under the compression elastic force of the elastic component 5 when moving along the circumferential direction and/or the circumferential direction, thereby realizing the universal floating of the massage head component 4, so that the massage head component 4 can be better attached to the neck of a human body, and achieving better massage effect.

It can be added that the elastic member 5 can be a spring, and the spring should always be in a compressed state, so that the spring can have a compression deformation force in the compressed state for pushing the connecting rod 3 abutting against it to move circumferentially and/or axially relative to the fixing member 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.

Moreover, as for the size of the inner cavity 21 of the fixing member 2, the size is determined according to the outer diameter of the portion of the connecting rod 2 extending into the inner cavity 21, so that the portion of the connecting rod 3 extending into the inner cavity 21 can slide relative to the inner wall of the inner cavity 21 to realize axial movement and can rotate relative to the inner wall of the inner cavity 21 to realize circumferential movement, which is not specifically limited in this embodiment.

In addition, the fixing member 2 and the connecting rod 3 may be made of a material with certain rigidity, for example, a material such as plastic or plastic may be used, and the material is specifically selected according to actual needs, which is not specifically limited in this embodiment.

It should be noted that, in the present embodiment, the massage head assembly 4 is specifically an assembly having a plurality of massage heads, and the plurality of massage heads can perform massage by using vibration massage or current stimulation massage, for example, when vibration massage is used, the massage head assembly 4 may be provided with a button vibration motor, and the button vibration motor drives the massage heads to perform vibration massage. The specific massage principle and the corresponding functional components of the massage head are not limited in detail in this embodiment, and can be selected according to actual needs. Moreover, the type of the button vibration motor can be selected from common types, and the embodiment also does not specifically limit the type. For example, when the current stimulation massage mode is adopted, the massage head assembly 4 can be provided with electrode plates, and different pulses are output to the electrode plates through the pulse generating device, so that the current stimulation massage function is provided for the human body.

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 likely 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 smaller than the radial dimension of the mounting portion 22, so as to lock the mounting portion 22 and avoid the mounting portion 22 falling off from the gap. The radial dimension here refers to a dimension in the left-right direction as in fig. 3a, i.e., a width dimension or an outer diameter dimension of the mounting portion 22.

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 a horn-shaped opening 113 which is open towards the fixing member 2, and the horn-shaped opening is used for guiding the mounting portion 22, so that the mounting portion 22 and the clamping portion 111 can be conveniently connected and assembled, and the mounting efficiency can be improved.

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 component 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 elastic component 5 close to the massage head component 4 is clamped in the clamping groove 312 for positioning the elastic component 5, and the problem that the one end of the elastic component 5 close to the massage head component 4 is unreliable due to the fact that there is no limit device for abutting with the connecting rod 3 is prevented.

It should be noted that the size of the snap groove 312 may be specifically determined according to the size of the elastic member 5, 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 is formed, thereby avoiding the interference between the massage head component 4 and the elastic member 5 when the massage head component moves circumferentially, and improving the use reliability.

Further, in the present embodiment, referring to fig. 3a and 3b, the radial dimension (i.e. the dimension in the left-right direction) of the cross section of the second-stage connecting rod 32 gradually increases in the direction approaching the first housing 11, so that the outer surface of the second connecting rod 32 is convex, the inner wall surface of the fixing part 2 contacted with the second connecting rod 32 is formed into a surface matched with the convex surface, since the inner wall surface of the fixing member 2 contacting the second-stage connecting rod 32 is formed in a concave shape fitting the convex outer surface of the second-stage connecting rod 32, and the convex and concave surfaces can be matched to play a guiding role, so that the fixing piece 2 and the second section of connecting rod 32 realize automatic centering through the concave-convex surface matching, and the second section of connecting rod 32 can return to the initial position when resetting, so that the repeatability of the movement of the massage head assembly 4 is improved.

Moreover, it should be added that the surface matching between the fixing member 2 and the second section of connecting rod 32 is a concave-convex surface, and the concave-convex surface 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 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 thus the second connecting rod 32 can move in the fixing member 2 along the axial direction and/or the circumferential 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.
