The utility model provides a neck massage appearance.

In the embodiment of the present invention, as shown in fig. 1 and 2, the neck massager 10 includes a housing 11, a massage head 12, a main control board 13 and a battery 14.

The housing 11 is used for supporting the massage head 12, the main control board 13, the battery 14 and other elements.

The massage head 12 is provided on the housing 11 for massaging the neck. In the present embodiment, there are two massage heads 12, and the two massage heads 12 are arranged at intervals along the circumferential direction of the neck massager 10.

The main control board 13 is arranged in the shell 11, and the main control board 13 is electrically connected with the massage head 12 and used for controlling the massage head 12 to work. When the neck massager 10 is a low-frequency micro-current massager, the main control board 13 controls the massage head 12 to generate low-frequency micro-current; when the neck massager 10 can generate both low-frequency micro-current and vibration (a vibrator is arranged in the massage head 12), the main control board 13 controls the massage head 12 to generate low-frequency micro-current and/or vibration, wherein the low-frequency micro-current, the vibration and the like act on the massage part to generate positive effects on the massage part.

The battery 14 is disposed in the housing 11 for supplying power to each element of the neck massage apparatus 10, such as the massage head 12 and the main control board 13.

In the present embodiment, the housing 11 is adapted to be worn on the neck, and the shape of the housing is adapted to the shape of the neck.

In the present embodiment, the housing 11 includes an intermediate section 11a, two elastic arms 11b, and two clipping arms 11 c. The two elastic arms 11b are respectively arranged at two ends of the middle section 11a and are positioned at the same side of the middle section 11 a. The two clamping arms 11c are respectively connected with one end of the two elastic arms 11b far away from the middle section 11a in a one-to-one correspondence manner. In the present embodiment, both massage heads 12 are provided on the intermediate section 11 a.

When wearing the neck massager 10, the elastic arm 11b can expand outward with the end point of the middle section 11a as a fulcrum and elastically deform, so that a sufficient gap is formed between the two clamping arms 11c to allow the neck of the human body to pass through, and then the elastic arm 11b returns under the action of the return force to allow the clamping arms 11c and the massage head 12 to be attached to the skin of the neck of the human body, so that the neck massager 10 can be stably worn and is not easy to separate from the neck.

In the present embodiment, when the neck massage apparatus 10 is worn, the elastic arms 11b, the clip arms 11c, and the massage head 12 are all in close contact with the neck skin of the human body. In this way, the neck massager 10 can be worn more stably without being easily detached from the neck.

In this embodiment, the elastic arms 11b, the clip arms 11c and the massage head 12 are all curved surfaces on the side that is attached to the neck skin of the human body. Therefore, the neck can be better attached. Specifically, in the present embodiment, the middle section 11a, the elastic arm 11b, the clipping arm 11c and the massage head 12 are all arc-shaped.

In this embodiment, the outer diameter of the elastic arm 11b is smaller than that of the middle section 11a, and the outer diameter of the elastic arm 11b is smaller than that of the clipping arm 11 c.

In the present embodiment, when the middle section 11a, the elastic arm 11b and the clip arm 11c are irregular (non-cylindrical), the outer diameter refers to the distance between two points on the edge of any cross section of the element.

The outer diameter of the elastic arm 11b is smaller than the outer diameter of the middle section 11a, which means that the maximum outer diameter of the elastic arm 11b is smaller than the minimum outer diameter of the end surface of the middle section 11a close to the elastic arm 11b, preferably, the maximum outer diameter of the elastic arm 11b is smaller than the minimum outer diameter of the middle section 11 a. Similarly, the outer diameter of the elastic arm 11b is smaller than the outer diameter of the clipping arm 11c, which means that the maximum outer diameter of the elastic arm 11b is smaller than the minimum outer diameter of the clipping arm 11c near the end surface of the elastic arm 11b, and preferably, the maximum outer diameter of the elastic arm 11b is smaller than the minimum outer diameter of the clipping arm 11 c.

In traditional neck massage appearance, the casing includes elastic support and two arm lock usually, for the syllogic casing, wherein, the external diameter of elastic support and the external diameter of arm lock are steady transition usually, and the concrete expression is that the external diameter that the terminal surface of elastic support is close to the arm lock is roughly the same with the external diameter that the arm lock is close to the terminal surface of elastic support. Due to the structural and technological limitations, the three-section type shell is not beneficial to further reducing the size of the neck massager, and is also not beneficial to miniaturizing the neck massager.

In the above-mentioned neck massager 10, the housing 11 includes the middle section 11a, the two elastic arms 11b and the two clamping arms 11c, that is, the housing 11 is a five-section housing, and the outer diameter of the elastic arm 11b is controlled to be smaller than the outer diameter of the middle section 11a, and the outer diameter of the elastic arm 11b is controlled to be smaller than the outer diameter of the clamping arm 11c, so that the neck massager 10 with a smaller size can be obtained, and the neck massager 10 can be more miniaturized.

In addition, in traditional neck massage appearance, the external diameter that the elastic support is close to the one end of arm lock is relatively great, promptly the width that the elastic support is close to the one end of arm lock is relatively great, wears neck massage appearance back, has obvious centre gripping sense.

In the neck massager 10, since the outer diameter of the elastic arm 11b is relatively small, that is, the width of the elastic arm 11b is relatively small, when the neck massager 10 is worn and the elastic arm 11b is tightly attached to the neck skin of a human body, the elastic arm 11b with the small width can reduce the clamping feeling compared with the elastic arm with the large width, so that the wearing does not have obvious clamping feeling.

In the embodiment, the elastic arm 11b includes an elastic strip 110, and two ends of the elastic strip 110 are respectively connected to the middle section 11a and the clamping arm 11 c. In this embodiment, the elastic strips 110 are multiple (two or more) and are arranged at intervals. Thus, the elastic arm 11b having a smaller size is advantageously obtained, and the elastic arm 11b having a better elasticity is advantageously obtained. In this embodiment, many elastic strips 110 are arranged at intervals in up-down direction (human height direction), and every elastic strip 110 all is the arc, and under the wearing state, every elastic strip 110 homoenergetic and neck laminating. In this embodiment, the number of the elastic strips 110 is two. Thus, the elastic arm 11b having a smaller size is advantageously obtained, and the elastic arm 11b having a better elasticity is advantageously obtained.

In the present embodiment, the main control board 13 and the battery 14 are both disposed in the intermediate section 11 a. In this embodiment, the intermediate section 11a is a hard shell having substantially no elasticity. Thus, the middle section 11a can better support the massage head 12, the main control board 13 and the battery 14, and the shell 11 is prevented from generating elastic deformation to influence the stability of the electric connection among the electric elements.

In traditional neck massager, main control board and battery are located two arm lock respectively in, and the size (width) of the arm lock that bears main control board and battery is great, leads to wearing to have obvious centre gripping sense.

In the neck massager 10, the main control board 13 and the battery 14 are both disposed in the middle section 11a, and the clamp arms 11c having a relatively small size (width) can be used, so that the feeling of clamping when the neck massager 10 is worn can be reduced.

In the present embodiment, the intermediate section 11a includes an outer shell 122 and an inner shell 124 detachably connected to each other in the radial direction of the neck massager 10, and the inner shell 124 is closer to the neck with respect to the outer shell 122. In this embodiment, the outer shell 122 and the inner shell 124 are hard shells, which have substantially no elasticity, and the outer shell 122 and the inner shell 124 are fixed by screws.

In this embodiment, the inner shell 124 includes an inner plate 1242 and two side plates 1244, and the two side plates 1244 are respectively disposed on two sides of the inner plate 1242 in the width direction. The outer shell 122 is disposed on a side of the side plate 1244 away from the inner plate 1242, and encloses the inner shell 112 to form a hollow cavity 120.

The main control panel 13 is fixed to the inner panel 1242 of the middle section 11 a. The main control panel 13 is provided with a charging plug 13a, the side plate of the middle section 11a is provided with a jack 124a, and the charging plug 13a is inserted into the jack 112. In this way, the main control panel 13 can be more stably fixed to the inner panel 1242.

In the present embodiment, the battery 14 is provided on the surface of the main control panel 13 away from the inner panel 1242. Thus, the wiring for electrically connecting the battery 14 and the main control board 13 can be shortened.

In the present embodiment, the battery 14 is bonded to the main control board 13, and the battery 14 abuts against the case 122 of the intermediate section 11 a. In this way, the battery 14 can be firmly connected to the main control board 13, and the battery 14 can limit the movement of the main control board 13 in the radial direction of the neck massager 10, so that the main control board 13 can be more stably fixed on the inner board 1242.

In this embodiment, the two clamping arms 11c are a first clamping arm and a second clamping arm respectively. As shown in fig. 4, the neck massager 10 further includes a first key plate 15 and a second key plate 16, wherein the first key plate 15 and the second key plate 16 are respectively disposed in the first clamping arm and the second clamping arm. The first clip arm is provided with a first key 130, and the first key 130 is arranged corresponding to the first key plate 15. The second clip arm is provided with a second key 140, and the second key 140 is disposed corresponding to the second key plate 16.

In traditional neck massage appearance, the main control board is located respectively in two arm lock with the battery to integrated keypad on the main control board, and do not set up the keypad alone. The keypad is integrated on the main control board, because the size of main control board is limited by the size of arm lock, leads to the space of the integrated keypad of main control board limited, and the quantity of the integrated button is limited in limited space, is unfavorable for satisfying the diversified demand of user's operation.

In the neck massager 10, the main control board 13 and the battery 14 are both disposed in the hollow cavity 120 of the middle section 11a, and the first key board 15 and the second key board 16 are respectively disposed in the first clamping arm and the second clamping arm, and the two key boards can be provided with more keys in a limited space relative to one key board, so as to meet the diversified requirements of user operations. Moreover, the size of the first key sheet 15 and the second key sheet 16 is generally smaller than the size of the main control board 13 and the battery 14, so that the clamping arms 11c with relatively small size (width) can be used, and the wearing feeling is not obvious.

In this embodiment, when the neck massager is worn on the neck, the middle section 11a corresponds to the back of the neck, the two elastic arms 11b correspond to the left and right sides of the neck, and the two clipping arms 11c correspond to the front of the neck. The first button 130 and the second button 140 are disposed in the clamping arm 11c located in front of the neck, which is very convenient for the user to operate the buttons.

In the present embodiment, the first button 130 is different from the second button 140, so that the fool-proof function can be achieved. In the present embodiment, the first key 130 is one of an on-off key and a mode selection key, and correspondingly, the first key board 15 is one of an on-off board and a mode selection board; the second key 140 is the other of the switch key and the mode selection key, and correspondingly, the second key board 16 is the other of the switch board and the mode selection board. Specifically, in this embodiment, the first button 130 is an on-off button, and the first button plate 15 is a switch plate; the second key 140 is a mode selection key and the second key pad 16 is a mode selection pad.

In the present embodiment, as shown in fig. 1 to 7, the massage head 12 includes a connection member 12a and an electrode assembly 12b, and the connection member 12a connects the intermediate section 11a and the electrode assembly 12b, so that the electrode assembly 12b is provided on the case 11. In other embodiments, the connecting component 12a may be integrally formed with the middle section 11a, or may be independent, and in this case, the massage head 12 may not include the connecting component 12 a.

In the present embodiment, the connection assembly 12a includes an elastic column 200, one end of the elastic column 200 is connected to the middle section 11a of the case 11, and the other end is connected to the electrode assembly 12 b. When the neck massager 10 is worn, the electrode assembly 12b is attached to the neck, and the neck applies an external force to the electrode assembly 12b, and the external force is transmitted to the elastic column 200. Because the elastic column 200 has elasticity, the elastic column 200 can be twisted and deformed along the circumferential direction of the elastic column 200 and compressed along the axial direction of the elastic column 200, so that the electrode assembly 12b can be deformed along with the deformation of the elastic column 200 when being worn, can better adapt to necks of different human bodies (sizes), and realizes a better fitting effect.

In this embodiment, the elastic column 200 is similar to a bellows. The elastic column 200 includes a hollow tube 210 and a plurality of pleats 220 protruding from the outer wall of the hollow tube 210, and two adjacent pleats 220 define a groove 202. In this manner, the elasticity of the elastic column 200 can be increased. Also, the hollow tube 210 may be used for wiring (electrically connecting the electrode assembly 12b with the conductive member of the main control board 13 or the battery 14).

In the present embodiment, the plurality of pleats 220 are arranged along the axial direction of the hollow tube 210. Thus, the elastic column 200 is more easily deformed. In other embodiments, the plurality of pleats 220 may also be arranged along the circumference of the hollow tube 210.

In the present embodiment, the outer wall of the elastic column 200 is recessed to form a groove 202, so that the elastic column 200 comprises a hollow tube 210 and a pleat 220. I.e. the hollow tube 210 is integrally formed with the pleats 220. In the present embodiment, the corrugation 220 refers to a member for forming the groove 202, and the shape thereof may be arbitrary. For example, in some embodiments, the plurality of pleats 220 are spaced apart, and the plurality of pleats 220 are independent of and unconnected to each other. In some embodiments, the plurality of pleats 220 extend helically forming a spring-like structure.

In the present embodiment, the wall thickness of the hollow tube 210 is 1mm or less. In this way, excessive rigidity of the hollow tube 210 can be avoided.
