Detailed implementation manners

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0031] As Figures 1 to 7 , a portable handheld muscle relaxation device of the present utility model includes a handle 1, a drive motor 2, and a massage rod 3.

[0032] The handle 1 is arc-shaped, the massage rod 3 is installed between the two ends of the arc of the handle 1, the drive motor 2 is installed inside one end of the handle 1, and the drive motor 2 drives the massage rod 3 to rotate around the line connecting the two ends of the handle 1; the massage rod 3 includes a main shaft 31 and a plurality of massage heads 32, the two ends of the main shaft 31 are rotatably connected to the two ends of the handle 1, and the massage heads 32 are circumferentially spaced and distributed on the outer periphery of the main shaft 31.

[0033] In this way, the arc-shaped handle 1 is provided to facilitate targeted relaxation massage on various parts of the body. Moreover, the massage rod 3 can be driven by the drive motor 2 to achieve electric rotation. Through the circumferential rotation of multiple massage heads 32, the effect of rolling massage can be achieved, saving effort and eliminating the need to manually roll the massage heads 32, thus easily and conveniently achieving muscle relaxation.

[0034] As Figure 7 shown, the massage rod 3 further includes a massage assembly 33. The massage assembly 33 includes two turntables 331 arranged at intervals left and right, and a number of connecting shafts 332. The number of connecting shafts 332 is equal to the number of massage heads 32. In this embodiment, the number of both the massage heads 32 and the connecting shafts 332 is six. During the rotation of the massage rod 3, the massage heads 32 are circumferentially spaced and all perform circular motion around the main shaft 31, achieving the effect of vibrating massage.

[0035] As Figure 5 shown, the two turntables 331 can be respectively sleeved on both ends of the main shaft 31 and rotate synchronously with the main shaft 31. An installation plane 311 can be provided on the main shaft 31 to cooperate with the flat installation holes 3311 on the turntables 331 to achieve synchronous rotation.

[0036] As Figure 2 shown, both ends of the main shaft 31 can be rotatably fitted with both ends of the handle 1 through bearings 312.

[0037] Both ends of each connecting shaft 332 are respectively connected to the two turntables 331, and the connecting shafts 332 are circumferentially spaced and distributed on the outer periphery of the main shaft 31. The massage heads 32 are rotatably sleeved and fixed on the outer periphery of the connecting shafts 332. Thus, when the main shaft 31 is driven by the drive motor 2 to rotate, it will drive the turntables 331 and the massage heads 32 on the connecting shafts 332 to rotate.

[0038] In this embodiment, a number of protruding shaft hole seats 3312 are circumferentially spaced on the opposite sides of the two turntables 331. Shaft holes 3313 are provided on the shaft hole seats 3312. Both ends of each connecting shaft 332 are respectively inserted and fixed in the shaft holes 3313. Each connecting shaft 332 can be tightly fitted and inserted into the shaft hole seats 3312 to facilitate product assembly. The connecting shafts 332 can be made of hard metal material to support the massage heads 32.

[0039] Refer to Figure 6, the interior of the massage head 32 has a cavity 321 that penetrates through both ends for the connecting shaft 332 to pass through. Sleeve bushings 333 are tightly and fittingly embedded at the openings at both ends of the massage head 32, and the sleeve bushings 333 have sleeve bushing holes 3331 that are in clearance fit with the connecting shaft 332. The sleeve bushing 333 can be made of wear-resistant materials such as POM. Thus, during the rotation of the massage rod 3, the massage head 32 can not only revolve around the main shaft 31 but also rotate on its own through the cooperation between the sleeve bushing 333 and the connecting shaft 332, enhancing the rolling massage effect.

[0040] Moreover, the massage head 32 of this embodiment can be in the shape of a candied haws. A number of massage protrusions 322 are arranged on the massage head 32 along the axial direction of the connecting shaft 332, and the spaces between the massage protrusions 322 are massage recesses 323; the massage protrusions 322 between the circumferentially adjacent massage heads 32 are distributed in an alternating manner. Thus, better massage effects and vibration effects can be achieved. As the drive motor 2 drives the massage rod 3, while driving the massage head 32 to revolve, a free rotation is generated, enabling the alternating impact of the concave and convex massage heads 32 on the position to be relaxed without generating useless resistance, achieving the effect of impact vibration relaxation at any position.

[0041] As Figure 5 and Figure 7 shown, two turntables 331 can respectively extend connecting sleeves 3314 relatively. When the two turntables 331 are fixed at both ends of the main shaft 31, the two connecting sleeves 3314 abut and are connected to each other, and at the same time, the two connecting sleeves 3314 are sleeved and fixed on the outside of the main shaft 31. In this embodiment, the connecting sleeves 3314 are connected through a concave-convex structure, which can facilitate the assembly of the product. At the same time, the two turntables 331 are connected as a whole, which can improve the structural strength of the product and extend the service life of the product to adapt to the vibration intensity of the massage.

[0042] As Figure 2 and Figure 3 shown, one end of the handle 1 has a first chamber 11, the drive motor 2 is installed in the first chamber 11, a worm 21 is provided at the output end of the drive motor 2, and one end of the main shaft 31 extends into the first chamber 11 and is sleeved and fixed with a worm gear 22, and the worm gear 22 meshes with the worm 21. In this embodiment, the worm 21 is taken as an example of a double-headed worm, but not limited thereto; through the cooperation of the double-headed worm 21 and the worm gear 22, the transmission ratio is small, enabling the main shaft 31 to have a higher rotational speed to meet the massage rotational speed requirements.

[0043] At the same time, a second chamber 12 is provided inside the other end of the handle 1, and a battery 4 can be installed in the second chamber 12. The battery 4 is used to supply power to the drive motor 2. The battery 4 and the drive motor 2 are placed at opposite ends of the handle 1 to keep the center of gravity of the product centered, facilitating hand-held use.

[0044] Moreover, a third chamber 13 may be provided inside the handle 1. The third chamber 13 communicates with the first chamber 11. In this embodiment, the handle 1 may be formed by snap-fitting two front and rear housings 14. The first chamber 11, the third chamber 13, and the second chamber 12 may communicate with each other and are surrounded by the two housings 14.

[0045] And a control circuit board 5 may be installed in the third chamber 13. The control circuit board 5 is electrically connected to the drive motor 2, and the control circuit board 5 has a control switch 51 exposed on the outer surface of the handle 1. Thus, by pressing the control switch 51, the operation of the drive motor 2 can be controlled, and the rotation speed of the massage head 32 can be controlled to change. In this embodiment, it can be divided into three speed gears, and different vibration frequencies of the massage stick can be realized, which are suitable for different massage needs.

[0046] As Figure 1 shown, the arc-shaped middle part of the handle 1 in this embodiment is the holding part 15, and there is a holding space 16 between the holding part 15 and the massage stick 3; so that it is convenient for the user to stretch the palm through the holding space 16 and firmly hold the holding part 15.

[0047] In this embodiment, Braille 17 is also provided on the outer surface of the holding part 15 of the handle 1; to facilitate the use by blind people.

[0048] Moreover, on the outer surfaces of both ends of the handle 1 near the massage stick 3 inside the holding space 16, indicating protrusions 18 protrude for identification when touched by the fingers of blind people. The indicating protrusions 18 are used to indicate that the area below is the area where the rotating massage stick 3 is located.

[0049] In summary, by setting the drive motor 2 to drive the massage stick 3 between the two ends of the arc-shaped handle 1 to rotate, the present invention can achieve a relaxed and labor-saving rolling massage to fully relax the muscles.
