The utility model provides a neck massage appearance.

As shown in fig. 1-3, in the present embodiment, the neck massager 10 includes a support 12, a battery 14, a control board 16, and a massage head 18.

The support 12 is used to support the elements. The bracket 12 includes a resilient arm 200 and two clip arm structures 300. The two clamping arm structures 300 are respectively disposed at two ends of the elastic arm 200, and the two clamping arm structures 300 are oppositely disposed and located at the same side of the elastic arm 200. Thus, when the neck massager 10 is used, the elastic arm 200 can be used to open and restore the neck massager 10 to fit different sizes of necks.

The battery 14 is disposed in one of the two clip arm structures 300, and the control main board 16 is disposed in the other of the two clip arm structures 300. The massage head 18 is provided on the elastic arm 200. The battery 14 is used to power the various components of the neck massager 10 that require power, such as the control board 16 and the massage head 18. The control main board 16 is connected with the massage head 18 in a communication way and is used for controlling the massage head 18 to work. When the neck massager 10 is a low-frequency micro-current massager, the control main board 16 controls the massage head 18 to generate low-frequency micro-current; when the neck massager 10 is a vibration massager, the control main board 16 controls the massage head 18 to vibrate, wherein low-frequency micro-current, vibration and the like act on the neck, and can produce positive effects on the neck. The batteries 14 and the control main board 16 are respectively disposed in the two clamping arm structures 300, so that the weight distribution of the whole neck massager 10 can be more balanced. The massage head 18 is used for massaging the neck. The massage head 18 can be directly contacted with the neck and cooperate with the two clip arm structures 300 to clip the neck.

In this embodiment, the two clamp arm structures 300 are substantially identical in construction, and the space and corresponding battery mount for assembling the battery 14 only differs from the space and corresponding motherboard mount for the control motherboard 16. The following description will be made mainly with respect to the common points of the two clamp arm structures 300.

As shown in fig. 1-3, the clamping arm structure 300 includes a housing 310 and an elastic bulge 320.

The housing 310 includes an inner surface 310a and an outer surface 310b, and the inner surface 310a is closer to the object to be clamped than the outer surface 310 b. In the present embodiment, the clip arm structure 300 is applied to the neck massager 10, and the object to be clipped is a neck. In other embodiments, when the clip arm structure 300 is applied to a lumbar massager, the object to be clipped is a lumbar; when the clamping arm structure 300 is applied to a leg massage apparatus, the clamped object is a leg. The inner side surface 310a and the outer side surface 310b may be flat or may be any non-flat surface such as a curved surface, and the inside and outside of the inner side surface 310a and the outer side surface 310b are mainly referred to as an object to be clamped.

The elastic bulge 320 is protruded from the inner side surface 310 a. When the clamped object presses the elastic bulge 320, the elastic bulge 320 is deformed under force, and the elastic bulge 320 is tightly attached to the clamped object alone or together with the inner side surface 310a located at the outer periphery of the elastic bulge 320.

When the clip arm structure 300 is worn, the elastic bulge 320 provides additional elastic close-fitting force, so that the wearing can be firmer. And the elastic bulge is stressed and deformed to be tightly attached to the clamped object, so that the elastic bulge is soft and skin-attached, and more comfortable feeling can be brought to a wearer.

Particularly, when the elastic bulge 320 and the inner side surface 310a located at the outer circumference of the elastic bulge 320 are tightly attached to the object to be clamped together, the inner side surface 310a can provide a close attachment force, so that the wearing can be further secured.

In the present embodiment, the elastic bulge 320 has a cavity 320a, and the cavity 320a facilitates deformation of the elastic bulge 320 and reduces the weight of the clipping arm structure 300. In other embodiments, the resilient bulge 320 may also be a solid body.

In this embodiment, the elastic bulge 320 is located in the middle of the inner side surface 310a, and when the elastic bulge 320 deforms under a force and is tightly attached to the clamped object, the outer periphery of the elastic bulge 320 deformed under a force has a circle of inner side surface 310a, that is, the inner side surface 310a of the outer periphery of the elastic bulge 320 deformed under a force is annular. So set up and more do benefit to stable centre gripping neck. It should be noted that the middle portion is not a strict middle portion, but only needs to satisfy "the inner side surface 310a of the outer periphery of the elastic bulge 320 deformed by force is annular".

In other embodiments, the elastic bulge 320 may also be located at the edge of the inner side surface 310a, and at this time, when the elastic bulge 320 deforms under a force and is tightly attached to the clamped object, the inner side surface 310a of the outer periphery of the elastic bulge 320 deformed under the force has a notch, and is not annular.

In the present embodiment, the housing 310 has a hollow structure. The inner side surface 310a is provided with a mounting hole 3122, and the mounting hole 3122 is communicated with the hollow cavity 310c of the housing 310. The side of the elastic bulge 320 far away from the clamped object is inserted into the mounting hole 3122. So, when elasticity swell 320 atress towards outside side 310b deformation, mounting hole 3122 can accommodate partial elasticity swell 320, provides deformation capacity for elasticity swell 320, more does benefit to firmly wearing, and more importantly, the pore wall all around of mounting hole 3122 can play the effect of supporting elasticity swell 320, and supplementary reinforcing elasticity swell 320 supports intensity, avoids elasticity swell 320 excessively recessed when using. In other embodiments, the mounting hole 3122 may be omitted, and in this case, the elastic bump 320 may be directly disposed on the inner side surface 310a by using an adhesive or the like.

Specifically, in the present embodiment, the housing 310 includes an inner shell 312 and an outer shell 314 that are detachably connected. In this manner, it is very convenient to assemble the elastic bulge 320 and disassemble and assemble the components disposed inside the housing 310. The inner shell 312 and the outer shell 314 are arranged along a direction from the inner side 310a to the outer side 310b, the inner side 310a is a side of the inner shell 312 away from the outer shell 314, and the outer side 310b is a side of the outer shell 314 away from the inner shell 312.

In the present embodiment, the elastic bump 320 is disposed through the mounting hole 3122, and a portion of the elastic bump 320 extends into the hollow cavity 310 c. The elastic bump 320 is attached to the hole wall of the mounting hole 3122 in a natural state, and is partially separated in a pressed state. The portion of the elastic bulge 320 extending into the hollow cavity 310c is connected to the housing 310. Specifically, in the present embodiment, the mounting hole 3122 is opened in the inner casing 312, and a portion of the elastic bump 320 extending into the hollow cavity 310c is connected to the inner casing 312. In other embodiments, the portion of the resilient bulge 320 extending into the hollow cavity 310c may also be connected to the housing 314.

The elastic bump 320 is attached to the hole wall of the mounting hole 3122 in a natural state, and is partially separated in a squeezed state, that is, the elastic bump 320 is a movable part relative to the hole wall of the mounting hole 3122, glue is not applied between the elastic bump 320 and the hole wall of the mounting hole 3122, and the elastic bump 320 is non-rigidly connected to the hole wall of the mounting hole 3122. Thus, after the elastic bulge 320 is extruded for multiple times, the elastic bulge 320 cannot be loosened due to degumming, and is more durable and higher in durability. In other embodiments, the elastic bulge 320 and the hole wall of the mounting hole 3122 may be fixed by gluing.

As shown in fig. 2-4, in the present embodiment, the elastic bump 320 includes a bump body 322 and a fixing ring 324 surrounding the bump body 322 for a circle. Specifically, in the present embodiment, the bulge body 322 is integrally formed with the fixing ring 324. Thus, the bulge body 322 and the fixing ring 324 are connected more tightly, glue is not easy to be separated, and meanwhile, the assembling procedure can be saved, so that the assembling time is saved. In other embodiments, the bulge body 322 and the fixing ring 324 may be connected by gluing or screwing.

The bulge body 322 is disposed through the mounting hole 3122, and the fixing ring 324 extends into the hollow cavity 310c and abuts against a circle of edge 3162 at the periphery of the mounting hole 3122 to close one end of the mounting hole 3122 near the outer side surface 310 b. Thus, it is possible to prevent external dust from entering the housing 310 through the mounting hole 3122. Moreover, when the housing 310 includes the inner shell 312 and the outer shell 314 detachably connected, the elastic bulge 320 can be installed from the inner side of the inner shell 312 (the side close to the outer shell 314), which is very convenient for assembly and disassembly.

In the present embodiment, the housing 310 includes a housing body and a mounting post 316. The housing body is hollow, the inner side 310a and the outer side 310b are two sides of the housing body, and the mounting posts 316 are disposed in the housing body. Specifically, in the present embodiment, the housing body includes an inner housing 312 and an outer housing 314 detachably connected, and the mounting post 316 is disposed on the inner housing 312 and located in the hollow cavity 310c of the housing 310. The mounting post 316 has opposite ends corresponding to the inner surface 310a and the outer surface 310b, respectively, and the mounting hole 3122 penetrates the opposite ends of the mounting post 316. A circle of edge 3162 on the periphery of the mounting hole 3122 is the end surface of the mounting hole 316 away from the inner side surface 310 a. The installation column 316 is arranged, so that the installation hole 3122 has a large depth, the elastic bulge 320 with a large size can be installed, and the elastic bulge 320 can deform along the extending direction of the installation hole 3122 when being extruded, so that a set deformation capacity is provided for the elastic bulge 320, and firm wearing is facilitated.

In other embodiments, the mounting posts 316 may be omitted, in which case the mounting holes 3122 extend through the wall of the inner casing 312, in which case a circle of the rim 3162 of the periphery of the mounting holes 3122 is the wall of the inner casing 312, and the fixing ring 324 abuts against and seals with a circle of the inner casing 312 of the periphery of the mounting holes 3122. Of course, the depth of the mounting hole 3122 may be increased by increasing the thickness of the wall of the inner case 312.

In this embodiment, the connection between the portion of the elastic bulge 320 extending into the hollow cavity 310c and the housing 310 includes at least one of clamping, gluing, and screwing. In this manner, not only is the retaining ring 324 interference sealed against the rim of the periphery of the mounting hole 3122, but assembly is also greatly facilitated.

Specifically, in the present embodiment, the inner casing 312 is provided with a fixing post 318, and the fixing post 318 is provided with an internal threaded hole 3182. The periphery of the fixing ring 324 is provided with a matching column 326, and the matching column 326 is provided with a matching hole 3262. The housing 310 also includes screws.

In one embodiment, the end surface of the mating post 326 abuts the end surface of the fixing post 318, and a screw is inserted through the mating hole 3262 and threadedly engaged with the internally threaded hole 3182 of the fixing post 318.

In one embodiment, the fixing post 318 is located at the periphery of the mounting post 316 and is connected to the side of the mounting post 316, and the height of the fixing post 318 is greater than the height of the mounting post 316. The fixing post 318 is inserted into the matching hole 3262, the screw is screwed with the internal threaded hole 3182 of the fixing post 318, and the size of the nut of the screw is larger than that of the matching hole 3262, so as to prevent the elastic bulge 320 from reversely falling off. Thus, the fixing posts 318 not only fix the elastic bumps 320, but also position the assembly of the elastic bumps 320.

In this embodiment, the elastic bulge 320 is separated from the inner casing 312 and fixed by screwing. In other embodiments, the elastic bulge 320 and the inner shell 312 may be integrally formed. In this way, the connection of the elastic bulge 320 and the inner shell 312 can be more secure, and the assembly process can be saved, thereby saving the assembly time.

In the present embodiment, the rigidity of the outer shell 314 is greater than the rigidity of the elastic bulge 320 and the inner shell 312, and the elastic bulge 320 and the inner shell 312 are relatively flexible. Specifically, in the present embodiment, the elastic bump 320 and the inner shell 312 are made of silicon rubber. Of course, in other embodiments, the elastic bulge 320 may be made of silicon rubber, and the inner casing 312 may be made of hard plastic.

In the present embodiment, a limiting member 328 is disposed on an end surface of the elastic bulge 320 near the outer side surface 310 b. The stop 328 serves multiple purposes.

In the present embodiment, the limiting member 328 has a function of interfering with the battery 14 disposed in the housing 310 to limit the movement of the battery 14. The limiting member 328 also has a function of preventing the elastic bulge 320 from being excessively extruded into the hollow cavity 310c and being unable to automatically recover when a gap 310d is formed between the limiting member 328 and a side of the elastic bulge 320 away from the outer side surface 310b, the gap 310d provides a limited deformation space for the elastic bulge 320. That is, the limiting member 328 has a certain width, and under the effect of the squeezing force, the side of the elastic bulge 320 away from the outer side surface 310b deforms toward the limiting member 328, and the limiting member 328 can prevent the elastic bulge 320 from further deforming, so as to prevent the elastic bulge 320 from being excessively squeezed into the hollow cavity 310c and not being automatically restored.

When the control main board 16 is disposed in the housing 310, the limiting member 328 is spaced apart from the control main board 16. Thus, the elastic bulge 320 is prevented from being excessively extruded into the hollow cavity 310c and being unable to automatically recover, and the limit member 328 is prevented from extruding the control main board 16 and damaging the control main board 16.

That is, in this embodiment, the elastic bulges 320 of the two clamping arm structures 300 (one clamping arm structure 300 is provided with the battery 14, and the other clamping arm structure 300 is provided with the control main board 16) are both provided with the limiting members 328, the battery 14 abuts against the limiting members 328 of the corresponding elastic bulges 320, and the spacing between the main board 16 and the limiting members 328 of the corresponding elastic bulges 320 is controlled. The position-limiting element 328 of each clamping arm structure 300 can prevent the elastic bulge 320 from being pressed into the hollow cavity 310c too much to be restored automatically.

In other embodiments, when the main purpose of the limiting member 328 is to prevent the elastic bulge 320 from being excessively pressed into the hollow cavity 310c and being unable to be automatically restored, when the battery 14 is disposed in the clamping arm structure 300, the battery 14 may be directly used as the limiting member 328; when the control main board 16 is disposed in the clamping arm structure 300, the control main board 16 can be directly used as the limiting member 328.

In this embodiment, the height of the elastic bulge 320 protruding from the inner side surface 310a is 1-10 mm. Thus, the phenomenon that the gravity center of the neck massager 10 moves backwards due to the fact that the height of the elastic bulge 320 is too high and the elastic bulge easily falls off can be avoided, too large elasticity is provided due to the fact that the height of the elastic bulge 320 is too high and the clamping is too tight can be avoided, and in addition, the phenomenon that the suitable wearing size is reduced due to the fact that the height of the elastic bulge 320 is too high can be avoided; the height of the elastic bulge 320 is too low, which causes the clip arm structure 300 not to be tightly attached to the neck and not to be fixed to the neck. Preferably, the height of the elastic bulge 320 protruding from the medial side 310a is 4-7 mm.

In this embodiment, the side 3222 of the elastic bulge 320, which is used for contacting with the clamped object, is an inward arc relative to the clamped object, that is, in the arrangement direction from the inner side 310a to the outer side 310b, the elastic bulge 320 is arc-shaped. Thus, the elastic bulge 320 deforms and gradually increases the contact area with the neck when being squeezed; meanwhile, the arc-shaped arch can provide more elasticity and larger space, components can be placed and protected in addition to providing more elasticity, and the elastic bulge 320 which is deformed is prevented from contacting with elements in the shell 310, namely, when the elastic bulge 320 is extruded, extrusion force is prevented from indirectly acting on the elements in the shell 310.

The above is only the optional embodiment of the present invention, and not the scope of the present invention is limited thereby, all the equivalent structure changes made by the contents of the specification and the drawings are utilized under the inventive concept of the present invention, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
