[0050] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0051] See also Figures 1 to 3 The present application embodiment discloses a neck massager, comprising an intermediate bracket 1, two handles 2 and two connecting components 3, and the two ends of the intermediate bracket 1 are respectively provided with a first mounting hole 11 (i.e. Figure 1 The lower end of the middle bracket 1 is provided with two first mounting holes 11), and the ends of the two handles 2 facing the middle bracket 1 are respectively provided with second mounting holes 21 (i.e. Figure 1 The upper end of the middle handle 2 is provided with two second mounting holes 21). The neck massager further comprises a power supply device (not shown) and a pulse device (not shown). The power supply device is mounted in the middle bracket 1 or the handle 2, and the pulse generating device is mounted in the middle bracket 1 or the handle 2.

[0052] Wherein, each connection component 3 includes:

[0053] A twistable tubular component 31, both ends of which are fixedly connected to the corresponding ends of the intermediate bracket 1 and the handle 2, respectively. The twistable tubular component 31 is used to bend and twist to adjust the distance and spatial orientation of the two handles 2;

[0054] The protective cover 32 is made of a flexible material and is sleeved on the outside of the twistable tubular component 31. The two ends of the protective cover 32 are respectively fixedly connected to the corresponding ends of the corresponding intermediate bracket 1 and the handle 2. The protective cover 32 includes a protective cover body 321, and a first connecting portion 322 and a second connecting portion 323 extending from the first end 321a and the second end 321b of the protective cover body 321 respectively.

[0055] The first connection portion 322 extends into and is fixed in the first mounting hole 11 corresponding to the intermediate bracket 1, the second connection portion 323 extends into and is fixed in the second mounting hole 21 corresponding to the handle 2, the end face of the first end 321a of the protective cover body 321 is fixedly abutted against the end face of the first mounting hole 11, so that there is no gap at the connection between the first end 321a of the protective cover body 321 and the intermediate bracket 1, the end face of the second end 321b of the protective cover body 321 is fixedly abutted against the end face of the second mounting hole 21, so that there is no gap at the connection between the second end 321b of the protective cover body 321 and the handle 2.

[0056] The embodiment of the present application realizes twisting of the handle at any angle by adding a connecting assembly 3 having a twistable tubular component 31 between the intermediate bracket 1 and the handle 2. Specifically, the two ends of the twistable tubular component 31 are fixedly connected to the corresponding ends of the corresponding intermediate bracket 1 and the handle 2, respectively, so the bending and twisting of the twistable tubular component 31 can drive the bending and twisting of the handle 2, thereby realizing the adjustment of the distance and spatial orientation between the two handles 2.

[0057] In order to protect the twistable tubular component 31 and prevent it from being damaged by external twisting force or particles such as sand and dust in the external environment, the embodiment of the present application provides a protective cover 32 made of flexible material on the outside of the twistable tubular component 31. Since the protective cover 32 is flexible and bendable, it can twist along with the bending and twisting of the twistable tubular component 31.

[0058] In order to prevent the protective cover 32 from generating a gap between the intermediate bracket 1 and the two handles 2 due to twisting, the embodiment of the present application fixes the two ends of the protective cover 32 to the corresponding ends of the intermediate bracket 1 and the handle 2, respectively, and the two connecting parts of the protective cover 32 are respectively extended into and fixed to the first mounting hole 11 and the second mounting hole 22, so that the two end faces of the protective cover body 321 are respectively fixedly abutted against the end faces of the first mounting hole 11 and the end faces of the second mounting hole 22, thereby achieving a stable fixed connection relationship between the two end faces of the protective cover body 321 and the end faces of the intermediate bracket 1 and the end faces of the handle 2, that is, there is no gap at the connection between the protective cover body 321 and the intermediate bracket 1 and the connection between the handle 2. In this way, although the protective cover is deformed to a certain extent due to the bending and twisting of the twistable tubular component, there will be no gap at the connection between the protective cover body and the handle and the intermediate bracket, and the protective cover will not be detached from the handle or the intermediate bracket. On this basis, since the connection between the protective cover and the handle and the middle bracket will not have gaps due to twisting, it can effectively prevent particles such as sand and dust from entering the neck massager through the gaps and affecting the service life of the neck massager, thereby achieving the effect of dust prevention and extending the service life of the neck massager.

[0059] In the embodiment of the present application, the first connection part 322 not only extends into the first mounting hole 11 of the intermediate bracket 1, but also the outer surface of the first connection part 322 is in contact with the inner surface of the first mounting hole 11; the second connection part 323 not only extends into the second mounting hole 21 of the handle 2, but also the outer surface of the second connection part 323 is in contact with the inner surface of the second mounting hole 21. The outer surfaces of the two connection parts are fully in contact with the inner surface of the intermediate bracket and the inner surface of the handle, respectively, which is conducive to further improving the connection stability between the connection part and the intermediate bracket and the handle, and further avoiding the problem of gaps at the connection between the protective cover and the intermediate bracket and the handle, or even the problem of the protective cover detaching during bending and twisting.

[0060] As an optional implementation, please refer to Figures 4 to 8 , showing the structure of the connection between the protective cover, the intermediate bracket and the handle. Figure 4 It is a structural exploded view of the connection between the protective cover 32, the intermediate bracket 1 and the handle 2. Figure 5 Specifically, it is a structural exploded view of the connection between the protective cover 32 and the intermediate bracket 1. Figure 6 and Figure 7 is a schematic diagram of the structure of the protective cover 32 at different viewing angles, Figure 8 Specifically, it is a structural exploded view of the connection between the protective cover 32 and the handle 2. Figures 4 to 6 The end surface of the first end 321a of the protective cover body 321 is concave toward the inside of itself (ie Figure 6 The first end 321a of the middle portion is recessed downward from the end surface to form a slot 41, and the end surface of the first mounting hole 11 is directed toward the slot 41 (i.e. Figure 5 The first mounting hole 11 in the middle extends downward to form a plug column 42, which is inserted into the slot 41 to achieve a fixed connection between the first end 321a of the protective cover body 321 and the first mounting hole 11, thereby achieving a fixed connection between the first connecting portion 322 and the intermediate bracket 1. Figures 7 and 8 The outer surface of the second connecting portion 323 is recessed toward its interior to form a limiting groove 51, and the inner surface of the second mounting hole 21 protrudes radially inward to form a limiting rib 52. The limiting rib 52 cooperates and is clamped in the limiting groove 51 to achieve a fixed connection between the second connecting portion 323 and the handle 2.

[0061] The limiting groove 51 and the limiting rib 52 used to realize the fixed connection between the protective cover 32 and the handle 2 are arranged along a direction perpendicular to the axial direction of the protective cover 32. Figure 8 The limiting groove 51 and limiting rib 52 shown are arranged roughly in the transverse direction. The limiting groove 51 and limiting rib 52 are arranged in a direction perpendicular to the axial direction of the protective sleeve 32, which can not only realize the fixed connection between the protective sleeve 32 and the handle 2, but also limit the movement of the connection between the handle and the protective sleeve in the axial direction, thereby further ensuring the connection stability between the end face of the second mounting hole 21 of the handle 2 and the end face of the second end 321b of the protective sleeve 32 during the twisting process, and ensuring that no gap is generated between the two end faces due to the twisting of the handle. At the same time, the slot 41 and the plug column 42 used to realize the fixed connection between the protective sleeve 32 and the intermediate bracket 1 are both arranged along the axial direction of the protective sleeve 32, that is, as shown in FIG. Figure 5 , Figure 6 The slots 41 and the columns 42 are arranged substantially vertically. The vertical insertion of the slots 41 and the columns 42 can guide the assembly of the protective cover and the intermediate bracket, and the protective cover can be installed more conveniently and quickly.

[0062] Please refer to Figure 2 The intermediate bracket 1 includes a bracket shell formed by a bracket outer shell 12 and a bracket inner shell 13 that are relatively arranged and matched, and the bracket outer shell 12 and the bracket inner shell 13 are relatively enclosed to form a first accommodating cavity, and the first mounting hole 11 is located at the end of the first accommodating cavity. Among them, the bracket outer shell refers to the shell part of the neck massager away from the neck when the user wears the neck massager, and the bracket inner shell refers to the shell part of the neck massager close to the neck when the user wears the neck massager. Designing the intermediate bracket 1 as a structure in which the bracket outer shell 12 and the bracket inner shell 13 are relatively arranged and matched, it is more convenient to more conveniently assemble the structure between the first mounting hole 11 of the intermediate bracket 1 and the protective cover 32.

[0063] In the embodiment of the present application, only one plug-in column 42 extends from the end face of the first mounting hole 11, and the plug-in column 42 is formed by being located on the bracket housing 12 and extending from the end face of the first mounting hole 11 toward the slot 41. That is to say, the pair of fixed connection structures of the plug-in column 42 and the slot 41 are arranged on the outer side of the neck massager (i.e., the side of the neck massager away from the neck) and are arranged on one side. When the user uses the neck massager, from the initial state, by utilizing the characteristics of the twistable tubular component 31, the two handles 2 can be moved outward to adjust the distance between the handles 2, and then the intermediate bracket 1 is placed on the neck to be massaged. In this process, the pair of fixed connection structures of the plug-in column and the slot arranged on the outer side can effectively reduce the influence of the pulling force caused by the outward movement of the handle, and further ensure that the connection between the intermediate bracket 1 and the protective cover 32 will not have a gap due to the movement of the handle 2.

[0064] It is understandable that the intermediate bracket may also have a bracket shell that is integrally formed and has a first accommodating cavity formed therein.

[0065] In the embodiment of the present application, in order to more fully ensure the tightness of the connection between the slot 41 and the plug-in column 42, an interference fit connection is adopted between the slot 41 and the plug-in column 42, so that the plug-in column 42 can be tightly inserted into the slot 41, so that the plug-in column 42 and the slot 41 are clamped together.

[0066] In the embodiment of the present application, the pair of slots 41 are formed by being recessed from the end surface of the first end 321a of the protective cover body 321 toward the interior of the protective cover body 321 itself, and the shape of the transverse cross section of the pair of slots 41 (i.e. Figure 6The cross-sectional shape of the first mounting hole 11 along the direction perpendicular to the axial direction of the protective sleeve 32 is C-shaped. Correspondingly, the plug-in column 42 formed on the inner surface of the first mounting hole 11 in the direction of the slot 41 is also a C-shaped plug-in column, so as to be inserted into the C-shaped slot 41 in a matching manner. Since the slot 41 and the plug-in column 42 are set to a C-shaped structure, the plug-in column 42 can be limited in two directions in the transverse cross-section of the slot 41, which is conducive to better connection and fixation between the slot 41 and the plug-in column 42.

[0067] See also Fig. 9 , the plug-in column 42 is surrounded by three rib plates to form a C shape, wherein the thickness of the rib plate is D, 1.0mm≤D≤1.5mm. As some optional embodiments, the thickness D of the rib plate is 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm or 1.5mm. If the thickness of the rib plate is too thin, the strength of the plug-in column 42 formed by the rib plate is too small to meet the structural strength requirements of the connection between the middle bracket and the protective cover during the movement of the handle 2; if the thickness of the rib plate is too thick, the plug-in column 42 formed by the rib plate may cause certain restrictions on the bending and twisting activities of the handle, and increase the material cost of processing the plug-in column. It can be understood that the thickness of the three rib plates can be the same or different, for example, the longer rib plate in the middle is thicker, and the two shorter rib plates on both sides are thinner. In addition, when the plug column is set to other shapes, the plug column is formed by other numbers of ribs. For example, when the plug column is set to an L shape, the plug column is formed by two ribs. There is no limit on the number of ribs.

[0068] In addition, the length of the plug post 42 extending in the axial direction is L, L≤5mm. As some optional embodiments, the length L of the plug post 42 is 5mm, 4.5mm, 4mm, 3.5mm, 3mm, 2.5mm or 2mm. When the length L of the plug post 42 is ≤5mm, it can reduce the use of injection molding materials and thus reduce processing costs, and can also avoid the problem of difficulty in the movement of the handle 3 caused by the excessive length of the plug post 42.

[0069] In addition, the recessed depth of the slot 41 is greater than or equal to the length L of the insertion column 42, thereby ensuring that the insertion column 42 can be fully inserted into the slot 41, and there will be no gap at the connection between the intermediate bracket 1 and the protective cover body 321 due to the insertion column 42 being too long and unable to be inserted into the bottom of the slot 41.

[0070] Please refer to Figure 7 and Figure 8The limiting groove 51 includes a first limiting groove 511 and a second limiting groove 512 which are arranged in parallel and at intervals, and the limiting rib 52 includes a first limiting rib 521 and a second limiting rib 522 which are arranged in parallel and at intervals. The first limiting groove 511 is formed by being recessed from the connection between the protective cover body 321 and the second connecting part 323 to the inside of the second connecting part 323, and the second limiting groove 512 is arranged on both sides of the second connecting part 323 in the width direction. Specifically, the second limiting groove 512 is arranged Figure 7 The first limiting rib 521 is formed to protrude inward from the end surface of the second mounting hole 21, so that the first limiting rib 521 is matched and clamped in the first limiting groove 511 at the connection between the protective cover body 321 and the second connecting part 323, so as to achieve fixed contact between the end surface of the second end 321b of the protective cover body 321 and the end surface of the second mounting hole 21. The second limiting rib 522 is formed to protrude inward from the inner surface of the second mounting hole 21 along the two sides in the width direction of the handle. Specifically, the second limiting rib 522 is arranged at Figure 8 The left and right sides of the middle handle 2 and the protruding positions of the second limiting ribs 522 correspond to the second limiting grooves 512 , so that the second limiting ribs 522 are matched and clamped in the second limiting grooves 512 .

[0071] It is understandable that the number of the limiting grooves 51 can also be three, four or more, and the number of the limiting ribs 52 can also be set to three, four or more, which is the same as the number of the limiting grooves 51. In addition, any limiting groove 51 can be a complete groove body that is connected as a whole, or any limiting groove 51 can also be composed of a number of independent groove bodies that are arranged at intervals. In addition, the limiting groove 51 can be set at the top of the second connecting part (that is, the connection between the second connecting part and the protective cover body), can be set in the middle position of the second connecting part, and can also be set at the bottom of the second connecting part (that is, the end of the second connecting part away from the protective cover body), which is not limited here. In order to achieve a good matching connection, the setting position of the limiting rib 52 is adapted to the limiting groove 51. By setting a plurality of parallel and spaced limiting grooves 51 and limiting ribs 52, the connection between the handle 2 and the protective cover 32 can play a role of overlapping limiting, which helps to make the connection between the handle 2 and the protective cover 32 more stable and reliable. The more limiting grooves and limiting ribs there are, the more conducive it is to improving the connection stability between the handle and the protective cover; but the more limiting grooves are opened, the greater the impact on the structural strength of the second connecting part, so the embodiment of the present application preferably uses two limiting grooves and two limiting ribs.

[0072] In addition, see Figure 2The handle 2 includes a handle shell formed by a handle outer shell 22 and a handle inner shell 23 that are relatively arranged and matched to each other, and the handle outer shell 22 and the handle inner shell 23 are relatively enclosed to form a second accommodating cavity, and the second mounting hole 21 is located at the end of the second accommodating cavity. Among them, the handle outer shell refers to the shell part of the neck massager away from the neck when the user wears the neck massager, and the handle inner shell refers to the shell part of the neck massager close to the neck when the user wears the neck massager. Designing the handle 2 as a structure in which the handle outer shell 22 and the handle inner shell 23 are relatively arranged and matched to each other makes it easier to assemble the structure between the second mounting hole 21 of the handle 2 and the protective cover 32. It should be noted that in the embodiment of the present application, protruding inward refers to protruding toward the inner direction of the handle or toward the inner direction of the intermediate bracket.

[0073] In the embodiment of the present application, the first limiting groove 511 located at the connection between the protective cover body 321 and the second connecting portion 323 is an approximately elliptical limiting groove, and the second limiting grooves 512 located on the left and right sides of the second connecting portion 323 are strip-shaped limiting grooves. The second mounting hole 21 is formed with a first limiting rib 521 extending from the end surface of the handle outer shell 22 and the end surface of the handle inner shell 23. The first limiting rib 521 is clamped in the first limiting groove 511 by the relative matching connection between the handle outer shell 22 and the handle inner shell 23, so as to fix the connection between the protective cover body 321 and the second connecting portion 323. The second limiting rib 522 is formed by protruding inward from the inner surface of the handle shell 22. The second limiting rib 522 is arranged on the handle shell 22 and is located on the left and right sides of the inner surface of the handle shell 22 to be clamped in the second limiting groove 512, further assisting the fixed connection and limiting effect between the first limiting rib 521 and the first limiting groove 411, so that the connection between the protective cover body 321 and the second connecting part 323 is more stable without any gap.

[0074] Among them, the first limiting groove 511 and the second limiting groove 512 can also be set as limiting grooves of other shapes such as rectangles, as long as the first limiting groove 511 can be adapted to the shape of the first limiting rib 521 located on the handle, so that the first limiting rib 521 can be matched and stuck in the first limiting groove 511, and the second limiting groove 512 can be adapted to the shape of the second limiting rib 522 located on the handle, so that the second limiting rib 522 can be matched and stuck in the first limiting groove 512, the specific shape is not limited here.

[0075] As for the fixed connection structure between the protective cover and the intermediate bracket and the handle, as another optional implementation, the end face of the second end of the protective cover body is recessed toward the inside to form a slot, and the second mounting hole extends toward the slot to form a plug-in column, which is inserted into the slot to achieve a fixed connection between the second end of the protective cover body and the second mounting hole, thereby achieving a fixed connection between the second connection part and the handle. The outer surface of the first connection part is recessed toward the inside to form a limiting groove, and the first mounting hole protrudes radially inward from the inner surface to form a limiting rib, which cooperates and is stuck in the limiting groove to achieve a fixed connection between the first connection part and the intermediate bracket. The above structure can also be used to achieve a fixed connection between the two ends of the protective cover and the intermediate bracket and the handle, respectively.

[0076] As for the fixed connection structure between the protective cover and the intermediate bracket and the handle, as other optional implementations, the outer surface of the first connecting part and the outer surface of the second connecting part may be recessed inward to form a limiting groove, and the first mounting hole and the second mounting hole may protrude radially inward from the inner surface to form a limiting rib, and the limiting rib may cooperate and be stuck in the limiting groove to realize the fixed connection between the two ends of the protective cover and the intermediate bracket and the handle respectively; it may also be that the end face of the first end and the end face of the second end are recessed inward to form a matching slot, and the first mounting hole and the second mounting hole are provided with a matching plug-in column extending in the direction of the matching slot, and the matching plug-in column is inserted into the matching slot, which can also realize the fixed connection between the two ends of the protective cover and the intermediate bracket and the handle respectively. Among them, when the fixed connections between the two ends of the protective sleeve and the intermediate bracket and the handle are all connected by the engagement and limiting connection of the limiting groove and the limiting rib, the limiting groove and the limiting rib are both arranged radially. At this time, not only can the two ends of the protective sleeve be respectively fixedly connected to the intermediate bracket and the handle, but also the axial movement of the connection between the handle and the protective sleeve and the axial movement of the connection between the intermediate bracket and the protective sleeve can be further limited, thereby further ensuring the connection stability between the end face of the second mounting hole of the handle and the end face of the second end of the protective sleeve during the twisting process, and ensuring the connection stability between the end face of the first mounting hole of the intermediate bracket and the end face of the first end of the protective sleeve during the twisting process, and further ensuring that after the above-mentioned end faces are abutted, there will be no gap or even direct detachment due to the bending and twisting of the twistable tubular component.

[0077] As for the fixed connection structure between the protective cover and the intermediate bracket and the handle, as another optional embodiment, the two ends of the protective cover are respectively fixedly connected to the intermediate bracket and the handle by screws. For example, the first connection part of the protective cover extends into the first mounting hole of the intermediate bracket and is fixedly connected to the inner surface of the first mounting hole by screws; the second connection part of the protective cover extends into the second mounting hole of the handle and is fixedly connected to the inner surface of the second mounting hole by screws. The screw-fixed connection can not only make the connection between the protective cover and the intermediate bracket and the handle more stable, but also make the protective cover and the twistable tubular component assembled and fixed together, thereby improving assembly efficiency.

[0078] See also Fig.10 The outer surface of the protective cover 32 is smoothly connected to the outer surface of the handle 2 and the outer surface of the intermediate bracket 1. Since the outer surfaces of the protective cover 32, the handle 2 and the intermediate bracket 1 are smoothly connected, and there is no gap at the connection between the protective cover 3, the handle 2 and the intermediate bracket 1, the integrity of the neck massager can be better reflected, and the integrity of the neck massager will not be destroyed due to the assembly and cooperation between multiple parts.

[0079] In the embodiment of the present application, the two ends of the twistable tubular component 31 are respectively fixed to the handle 2 by screws and fixed to the intermediate bracket 1 by screws. Figure 2 , Figure 3 , Fig.10 The upper end of the twistable tubular component 31 has an opening, which can be inserted into the first mounting hole 11 of the intermediate bracket 1 and fixedly connected to the inner surface of the first mounting hole 11 by screws; the lower end of the twistable tubular component 31 also has an opening, which can be inserted into the second mounting hole 21 of the handle 2 and fixedly connected to the inner surface of the second mounting hole 21 by screws, thereby realizing quick and stable installation between the twistable tubular component 31 and the handle 2 and the intermediate bracket 1. In particular, when the protective cover is also fixedly connected to the intermediate bracket and the handle by threads, the protective cover is installed together with the twistable tubular component to improve the efficiency of assembly.

[0080] In the embodiment of the present application, the twistable tubular component 31 and the protective cover 32 are connected by secondary molding, that is, the twistable tubular component 31 is firstly made by the first injection molding, and then the twistable tubular component 31 and the protective cover are co-injected to form the two into one piece, which not only improves production efficiency but also facilitates assembly operation. Among them, the twistable tubular component 31 is provided with a through inner cavity 311 along the axial direction, and the through inner cavity is used to facilitate the routing of the electrical components inside the neck massager.

[0081] In the embodiment of the present application, the twistable tubular component 31 is a bellows or a gooseneck tube. The twistable tubular component 31 has the characteristics of being able to bend and twist arbitrarily and having a controllable bending state, so as to achieve bending and twisting at any angle. The flexible material of the protective cover 32 is a composite of one or more of silicone material, soft polyethylene material, polypropylene material, ethylene-vinyl acetate copolymer material, polyolefin elastomer material or polyurethane elastomer material. The above materials have the characteristics of being flexible and bendable, so as to adapt to the arbitrary bending and twisting of the twistable tubular component. For example, the twistable tubular component 31 is a bellows, and the protective cover is made of silicone material, which is a silicone protective cover.
