This application proposes a neck massager.

In the embodiment of the present application, as shown in FIGS. 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 to support components such as the massage head 12, the main control board 13, and the battery 14.

The massage head 12 is arranged on the shell 11 and is used to massage the neck. In this embodiment, there are two massage heads 12, and the two massage heads 12 are arranged at intervals along the circumference of the neck massager 10.

The main control board 13 is arranged in the housing 11, and the main control board 13 is electrically connected with the massage head 12 for controlling the operation of the massage head 12. 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 (the massage head 12 has a built-in In the case of a vibrator), the main control board 13 controls the massage head 12 to generate low-frequency micro-currents and/or vibrations. Among them, the low-frequency micro-currents, vibrations, etc. act on the massaged part, which can have a positive effect on the massaged part.

The battery 14 is arranged in the housing 11 and is used to supply power to the components of the neck massager 10 that need to be powered, for example, to power the massage head 12 and the main control board 13.

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

In this embodiment, the housing 11 includes a middle section 11a, two elastic arms 11b, and two clamping arms 11c. Two elastic arms 11b are respectively arranged at both ends of the middle section 11a, and are located on the same side of the middle section 11a. The two clamping arms 11c are respectively connected to the ends of the two elastic arms 11b away from the middle section 11a in a one-to-one correspondence. In this embodiment, the two massage heads 12 are both arranged on the middle section 11a.

When wearing the aforementioned neck massager 10, the elastic arm 11b can expand to the outside with the end point of the middle section 11a as a fulcrum, and undergo elastic deformation, so that there is enough gap between the two clamping arms 11c for the human neck to pass through. Then the elastic arm 11b recovers under the action of the restoring force so that the clamping arm 11c and the massage head 12 are close to the skin of the human neck, so that the neck massager 10 can be stably worn and not easily detached from the neck.

In this embodiment, when the neck massager 10 is in the wearing state, the elastic arm 11b, the clamping arm 11c, and the massage head 12 are all close to the skin of the human neck. In this way, the neck massager 10 can be worn more stably and is not easily detached from the neck.

In this embodiment, the sides where the elastic arm 11b, the clamping arm 11c, and the massage head 12 adhere to the skin of the human neck are all curved surfaces. In this way, it can better fit the neck. Specifically, in this embodiment, the middle section 11a, the elastic arm 11b, the clamping 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 the outer diameter of the middle section 11a, and the outer diameter of the elastic arm 11b is smaller than the outer diameter of the clamping arm 11c.

It should be noted that, in this embodiment, when the middle section 11a, the elastic arm 11b, and the clamping arm 11c are irregular (non-cylindrical) shapes, the outer diameter refers to the distance between two points on the edge of any section of the element. .

The outer diameter of the elastic arm 11b is smaller than the outer diameter of the middle section 11a 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 middle section. The minimum outer diameter of the section 11a. Similarly, that the outer diameter of the elastic arm 11b is smaller than the outer diameter of the clamp arm 11c means that the maximum outer diameter of the elastic arm 11b is smaller than the minimum outer diameter of the end surface of the clamp arm 11c close to the elastic arm 11b. Preferably, the maximum outer diameter of the elastic arm 11b The diameter is smaller than the minimum outer diameter of the clamp arm 11c.

In a traditional neck massager, the shell usually includes an elastic bracket and two clamp arms, which is a three-segment shell. Among them, the outer diameter of the elastic bracket and the outer diameter of the clamp arm usually transition smoothly, specifically, elastic The outer diameter of the end surface of the bracket close to the clamping arm is approximately the same as the outer diameter of the end surface of the clamping arm close to the elastic bracket. Due to structural and technological limitations, the three-section housing is not conducive to further reducing the size of the neck massager, that is, it is not conducive to making the neck massager more compact.

In the aforementioned neck massager 10, the housing 11 includes a middle section 11a, two elastic arms 11b and two clamping arms 11c, that is, the housing 11 is a five-segment housing, and controls the outer diameter of the elastic arm 11b. It is smaller than the outer diameter of the middle section 11a, and the outer diameter of the control elastic arm 11b is smaller than the outer diameter of the clamping arm 11c, so that a smaller size neck massager 10 can be obtained, which makes the neck massager 10 more compact.

In addition, in the traditional neck massager, the outer diameter of the end of the elastic support near the clamp arm is relatively large, that is, the width of the end of the elastic support near the clamp arm is relatively large. After wearing the neck massager, there is obvious Grip feeling.

In the aforementioned 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, the neck massager 10 is worn, and the elastic arm 11b is close to the neck of the human body. In the case of skin, compared to the elastic arm with a larger width, the elastic arm 11b with a smaller width can reduce the gripping feeling, so that there is no obvious gripping feeling when wearing.

In this 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 11c. In this embodiment, there are multiple elastic strips 110 (more than or equal to two), and they are arranged at intervals. In this way, it is advantageous to obtain the elastic arm 11b with a smaller size, and it is advantageous to obtain the elastic arm 11b with better elasticity. In this embodiment, a plurality of elastic strips 110 are arranged at intervals in the up and down direction (human body height direction), and each elastic strip 110 is arc-shaped. In the wearing state, each elastic strip 110 can be connected to the neck fit. In this embodiment, there are two elastic strips 110. In this way, it is advantageous to obtain the elastic arm 11b with a smaller size, and it is advantageous to obtain the elastic arm 11b with better elasticity.

In this embodiment, the main control board 13 and the battery 14 are both arranged in the middle section 11a. In this embodiment, the middle section 11a is a hard shell, which is basically not elastic. In this way, the middle section 11a can better support the massage head 12, the main control board 13 and the battery 14, so as to avoid elastic deformation of the housing 11 and affect the stability of the electrical connection between the electrical components.

In the traditional neck massager, the main control board and the battery are respectively arranged in the two clamping arms, and the size (width) of the clamping arm that carries the main control board and the battery is relatively large, which leads to an obvious sense of clamping when worn.

In the above neck massager 10, the main control board 13 and the battery 14 are both arranged in the middle section 11a, and the arm 11c with a relatively small size (width) can be used, thereby reducing the wearing of the neck massager 10. The gripping feeling.

In this embodiment, in the radial direction of the neck massager 10, the middle section 11a includes an outer shell 122 and an inner shell 124 that are detachably connected, and the inner shell 124 is closer to the neck relative to the outer shell 122. In this embodiment, the outer shell 122 and the inner shell 124 are hard shells, which are basically not elastic, 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 second clamping arm is provided with a second button 140, and the second button 140 is arranged corresponding to the second button board 16.

In the traditional neck massager, the main control board and the battery are respectively arranged in the two clamping arms, and the key board is integrated on the main control board, instead of separately setting the key board. The button board is integrated on the main control board. Because the size of the main control board is limited by the size of the clamp arm, the space for the main control board to integrate the button board is limited. The number of buttons integrated in the limited space is limited, which is not conducive to satisfying users. Operational diversified needs.

In the above-mentioned neck massager 10, the main control board 13 and the battery 14 are both arranged in the hollow cavity 120 of the middle section 11a, and a first key board 15 and a first key board 15 and The second key board 16, two key boards relative to one key board, can be provided with more keys in a limited space, which can meet the needs of users for diversified operations. Moreover, the sizes of the first key board 15 and the second key board 16 are generally smaller than the sizes of the main control board 13 and the battery 14, so that a clamping arm 11c with a relatively small size (width) can be used, so that there is no obvious gripping feeling when wearing.

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 clamping arms 11c correspond to the front of the neck. The first button 130 and the second button 140 are arranged on the clamp arm 11c located in front of the neck, which is very convenient for the user to operate the buttons.

In this embodiment, the first button 130 is different from the second button 140, so that it can play a role in preventing fools.
