Description

Technical Field

[0001] This utility model relates to the field of massagers, specifically to an electric neck and back massage device. Background Technology

[0002] Neck and back massage devices, as a type of massager, are easy to install and use, and are widely used in car seats, office chairs, or sofas. To improve the massage effect and cater to people of different heights or to massage different body parts, the massage mechanism needs to be mobile. To address this issue, Chinese utility model patent CN204181862U discloses a multi-functional walking massager that can perform rotational and tapping massages while the massage mechanism is moving, achieving multi-directional massage of the body. In this massager, the lead screw is located on one side of the base and connected to one side of the massage mechanism. Driven by a second motor, the massage mechanism moves along the lead screw, achieving the walking massage function. However, because the drive component is located on one side of the base and massage mechanism, the stability of operation is not improved. Therefore, to avoid the shortcomings of the existing technology, it is necessary to improve it. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies in the existing technology and provide an electric neck and back massage device that operates smoothly and has an adjustable massage height.

[0008] Furthermore, the horizontal height of the inner bottom surface of the guide groove is higher than the horizontal height of the inner bottom surface of the mounting shell.

[0009] Furthermore, the mounting housing is provided with a fixing bracket, and the fixing bracket is provided with a first screw seat and a second screw seat. The screw passes through the first screw seat, the first nut, the second nut and the second screw seat in sequence and is installed on the first screw seat and the second screw seat.

[0010] Furthermore, ball bearings are installed inside the first screw seat and the second screw seat.

[0011] Furthermore, it also includes a battery and a control circuit board, wherein the control circuit board is electrically connected to the battery, the drive mechanism and the massage mechanism respectively.

[0012] Furthermore, the mounting housing has several mounting slots, and the battery, control circuit board and drive motor are respectively installed in the mounting slots.

[0013] Furthermore, the massage mechanism includes a rotating base, a massage motor that drives the rotating base to rotate, and a massage head mounted on the rotating base.

[0014] Furthermore, a lumbar pad or a lumbar heating pad is installed on the movable slider.

[0015] Compared with the prior art, this utility model provides a first nut and a second nut at the front and rear ends of the movable slider, so that the front and rear ends of the movable slider are screwed to the screw respectively, making the movable slider move more smoothly, preventing shaking, and improving operational stability.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 The electric neck and back massage device of this utility model includes a mounting shell 1, a movable slider 2 that slides within the mounting shell 1, a massage mechanism mounted on the movable slider 2, and a drive mechanism for driving the movable slider 2. Guide mechanisms 7 are provided on the left and right sides of the mounting shell 1, and the movable slider 2 slides within these guide mechanisms. The drive mechanism includes a drive motor 3, a screw 4 connected to the output end of the drive motor 3, and a first nut 5 and a second nut 6 respectively screwed to the screw 4. The first nut 5 and the second nut 6 are respectively located at the front and rear ends of the movable slider 2. The drive motor 3 directly drives the screw 4 to rotate, and the screw 4 can pass directly through the middle of the movable slider 2. The movable slider 2 moves synchronously via the first nut 5 and the second nut 6, improving operational stability. The drive motor 3 drives the screw 4 to rotate, and the movable slider 2 moves simultaneously, realizing the up-and-down movement of the massage mechanism.

[0023] The first nut 5 and the second nut 6 are ball bearing nuts, which make the operation smoother.

[0024] The guide mechanism 7 is a guide groove 8, which further limits the running trajectory of the moving slider 2 and prevents displacement. The horizontal height of the inner bottom surface of the guide groove 8 is higher than the horizontal height of the inner bottom surface of the mounting shell 1, reducing the contact area between the moving slider 2 and the bottom of the mounting shell 1 and reducing resistance.

[0025] The mounting housing 1 contains a fixing bracket 9, on which a first screw seat 10 and a second screw seat 11 are mounted. The screw 4 passes sequentially through the first screw seat 10, the first nut 5, the second nut 6, and the second screw seat 11 and is mounted on the first screw seat 10 and the second screw seat 11. This positioning of the screw 4 at both ends improves its operational stability.

[0026] Ball bearings are installed in the first screw seat 10 and the second screw seat 11.

[0027] It also includes a battery 12 and a control circuit board 13, which are electrically connected to the battery 12, the drive mechanism and the massage mechanism respectively.

[0028] The mounting housing 1 has several mounting slots, and the battery 12, control circuit board 13 and drive motor 3 are respectively installed in the mounting slots.

[0029] The massage mechanism includes a rotating base 14, a massage motor 15 that drives the rotating base 14 to rotate, and massage heads 16 mounted on the rotating base 14. The massage motor 15 drives the rotating base 14 to rotate, and the massage heads 16 on the rotating base 14 move in conjunction to achieve massage.

[0030] The mounting housing 1 is also covered with a cover plate, which has an opening for the massage mechanism to operate.

[0031] Of course, the massage mechanism can be omitted from the movable slider 2; instead, a lumbar cushion or lumbar heating pad can be directly installed for use as a lumbar support.

[0032] This utility model electric neck and back massage device can be installed in a shell made of pure cotton, latex or other breathable and comfortable materials, and can be used as a neck pillow, lumbar support, etc.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
