Description

Technical Field

[0001] This technical solution relates to the field of massage machine technology, specifically an adjustable distance massage machine. Background Technology

[0002] Massagers are devices that promote blood circulation and soothe muscles by using rotating, vibrating, and tapping massage heads to relieve physical discomfort. Common massage mechanisms utilize the rotation of the massage heads to massage specific areas, combined with a oscillating structure to achieve a kneading massage effect. In actual use, the areas that need massage are not limited to the neck, back, and waist. The spacing between the massage heads in conventional massage devices is not adjustable, so they cannot simultaneously massage multiple areas. Chinese patent CN116531231A discloses a massage head distance adjustment mechanism and a massager. This massage head distance adjustment mechanism includes two massage heads and an adjustment rod. The two massage heads move closer to each other or further apart through the thread action on the adjustment rod. However, this adjustment method has the following problems: 1. The threaded adjustment method has low mechanical efficiency and slow adjustment speed. It usually requires turning the adjustment rod several times to move the massage head a certain distance. In addition, a lot of friction and heat will be generated during this process, making the operation laborious.

[0003] 2. During the adjustment process, the connection between the adjustment rod and the massage head wears out quickly and significantly, which shortens the lifespan of the massager. Summary of the Invention

[0004] The purpose of this technical solution is to provide an adjustable-distance massager that solves the problems of cumbersome distance adjustment, low efficiency, and easy wear and tear in the original massager by adding an independently driven adjustable-distance component.

[0005] The purpose of this technical solution is achieved as follows: An adjustable-distance massager includes: a housing assembly with an internal chamber; a rotating assembly disposed within the chamber for rotating massage heads; and an adjusting assembly disposed within the chamber for adjusting the relative distance between the massage heads. The adjusting assembly includes: an adjusting drive with an adjusting screw at its output end; an adjusting drive wheel rotatably disposed within the chamber and meshing with the adjusting screw; at least two eccentric adjusting wheel sets, each connected to the adjusting drive wheel; and at least two adjusting nested members, movably disposed on adjusting slides of the housing assembly and connected to corresponding eccentric adjusting wheel sets. Two rotating gears of the rotating assembly are disposed within corresponding adjusting nested members. The rotating assembly also includes a rotating rod for mounting massage heads, disposed at the center of the rotating gears and extending sequentially beyond the adjusting nested members and the housing assembly. When the adjusting drive is activated, the adjusting drive wheel drives the eccentric adjusting wheel sets to rotate, simultaneously moving the adjusting nested members under the action of the adjusting slides, and then moving the rotating gears through the action of the rotating rod.

[0006] Preferably, the eccentric adjusting wheel assembly includes: an adjusting driven wheel that meshes with the adjusting driving wheel; an eccentric adjusting cam connected to the adjusting driven wheel; and an adjusting linkage with its rear end sleeved outside the eccentric adjusting cam and its front end connected to the adjusting nesting member.

[0007] Preferably, the adjustable nesting component includes a rear shell and a front cover, which cooperate to form a space for installing a rotating gear, and the front cover has a through hole for the rotating rod to pass through.

[0008] Preferably, the housing assembly includes a first housing, a second housing, and a third housing, with the second housing fastened to the first housing and the third housing fastened to the second housing. The first housing has an adjustable sliding track, and the surface of the rear housing is provided with a protrusion adapted to the adjustable sliding track. When the adjustable nesting member is placed in the cavity, the protrusion is movably engaged in the adjustable sliding track.

[0009] Preferably, the front end of the adjusting linkage has a mounting hole; the surface of the front cover has a mounting portion that adapts to the mounting hole.

[0010] Preferably, the pitch adjustment assembly further includes a speed adjustment gear, which is coaxially arranged with the pitch adjustment drive wheel; both the speed adjustment gear and the pitch adjustment drive wheel are mounted on the housing via shafts; the pitch adjustment driven wheel meshes with the speed adjustment gear.

[0011] Preferably, the second housing has a limiting groove; the adjustable nesting component is movably disposed within the limiting groove.

[0012] Preferably, the housing has a limiting hole; the rotating rod extends out of the limiting hole and is movably disposed within the limiting hole.

[0013] Preferably, the rotating assembly further includes a rotating drive component, both ends of which are provided with rotating screws, and the rotating gear meshes with the rotating screws.

[0014] The key and beneficial technical effects of this technical solution compared to existing technologies are: 1. The rotating component and the distance adjustment component designed in this technical solution are independently controlled. The rotating component is used to control the massage head to rotate and massage, and the distance adjustment component is used to control the movement of the massage head, so that the distance between the massage heads changes. This allows the massage machine to massage the neck, back, waist or other parts. The two components do not interfere with each other, which increases the adaptability and functionality of the massage machine.

[0015] 2. The pitch adjustment component designed in this technical solution is powered by the pitch adjustment drive component, the pitch adjustment drive wheel transmits the power, and the eccentric pitch adjustment wheel set receives the power, ultimately realizing the movement of the pitch adjustment nested component. During the driving process, the rotation of the pitch adjustment driven wheel is transformed into the movement of the pitch adjustment nested component through the eccentric pitch adjustment cam, which reduces energy loss, improves transmission efficiency, and reduces the wear between various parts.

[0024] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, an adjustable distance massager includes a housing assembly 1, a rotating assembly 2, and an adjusting assembly 3. The housing assembly 1 provides installation space for parts. The rotating assembly 2 and the adjusting assembly 3 are both installed in the cavity inside the housing assembly 1. The rotating assembly 2 is used to rotate the massage head, and the adjusting assembly 3 is used to adjust the relative distance between the massage heads. The rotating assembly 2 and the adjusting assembly 3 each have independent drive components and transmission components, so they work together without interfering with each other.

[0026] like Figure 2 and Figure 3 As shown, the massager includes at least two massage heads arranged opposite each other. When massaging different parts of the body, the distance between the two massage heads needs to be adjusted to obtain a better massage effect. Specifically, the rotating assembly 2 includes a rotating drive 21, a rotating screw 24, a rotating gear 22, and a rotating rod 23. The massage heads are installed on the end side of the rotating rod 23. The rotating drive 21 is configured as a motor. Since it needs to drive the two massage heads to work, rotating screws 24 are provided on both sides of the motor. Each rotating screw 24 is connected to a rotating gear 22. The rotating rod 23 is installed at the center of the rotating gear 22. When the motor drives the rotating screw 24, the rotating screw 24 and the rotating gear 22 are threaded together, which realizes the rotation of the rotating rod 23, thereby realizing the rotation of the massage heads. The rotating assembly 2 has an independent drive and can synchronously drive the two massage heads to rotate.

[0027] like Figure 2 and Figure 3As shown, the adjusting assembly 3 includes an adjusting drive 31, an adjusting screw 32, an adjusting drive wheel 33, an eccentric adjusting wheel set 34, and an adjusting nested part 35. The adjusting assembly 3 can synchronously drive the two massage heads to move. The adjusting drive 31 is configured as a motor, with the adjusting screw 32 at one end of the motor. The center of the adjusting drive wheel 33 is provided with a shaft 37. The adjusting drive wheel 33 is mounted on the housing assembly 1 through the shaft 37 and meshes with the adjusting screw 32. In this way, the motor can drive the adjusting drive wheel 33 to rotate.

[0028] Furthermore, the number of eccentric adjustment wheel sets 34 is set to two, each corresponding to a massage head, and simultaneously meshing with the adjustment drive wheel 33. Each eccentric adjustment wheel set 34 is connected to an adjustment nesting piece 35, and the transmission rod is inserted into the adjustment nesting piece 35. In this way, when the adjustment nesting piece 35 moves, it can drive the massage head to move through the rotating rod 23, thereby realizing the adjustment.

[0029] like Figure 2 and Figure 3 As shown, the eccentric adjusting wheel assembly 34 includes an adjusting driven wheel 341, an eccentric adjusting cam 342, and an adjusting connecting rod 343. The adjusting driven wheel 341 meshes with the adjusting driving wheel 33 and is mounted on the eccentric adjusting cam 342 by means of a protrusion and a groove, so that there is no relative rotation between the adjusting driven wheel 341 and the eccentric adjusting cam 342. One end of the adjusting connecting rod 343 is sleeved on the outside of the eccentric adjusting cam 342. The eccentric adjusting cam 342 has an annular groove on its periphery, which allows the adjusting connecting rod 343 to be sleeved. The other end of the adjusting connecting rod 343 is connected to the adjusting nesting piece 35.

[0030] Furthermore, such as Figure 7 As shown, since the connection between the adjustable driven wheel 341 and the eccentric adjustable cam 342 is eccentric relative to the eccentric adjustable cam 342, when the eccentric adjustable cam 342 rotates, it will push the adjustable nesting piece 35 to move, thus changing the rotation into movement, thereby realizing the adjustment between the massage heads.

[0031] like Figure 3 and Figure 4 As shown, the adjustable spacing nesting piece 35 includes a rear shell 351 and a front cover 352. The rear shell 351 and the front cover 352 are detachably connected by screws. The rear shell 351 and the front cover 352 cooperate to form a space for installing the rotating gear 22. The front cover 352 has a through hole 355 for the rotating rod 23 to pass through. Therefore, the rotating gear 22 and the adjustable spacing nesting piece 35 are simultaneously fitted outside the rotating rod 23. So when the adjustable spacing nesting piece 35 moves, it can drive the massage head to move. At the same time, the rotating gear 22 can also drive the massage head to rotate through the rotating rod 23.

[0032] Furthermore, the front end of the adjusting link 343 has a mounting hole 344, and the surface of the front cover 352 has a mounting portion 354 that adapts to the mounting hole 344, so that the adjusting link 343 and the front cover 352 can be detachably connected.

[0033] Furthermore, the pitch adjustment assembly 3 also includes a speed adjustment gear 36, which is coaxially arranged with the pitch adjustment drive wheel 33. Both the speed adjustment gear 36 and the pitch adjustment drive wheel 33 are mounted on the housing 11 via a shaft 37. The pitch adjustment driven wheel 341 meshes with the speed adjustment gear 36. Speed ​​adjustment can be achieved by adjusting the gear ratio between the pitch adjustment drive wheel 33, the speed adjustment gear 36, and the pitch adjustment driven wheel 341.

[0034] like Figure 3-5 As shown, the housing assembly 1 includes a first housing 11, a second housing 12, and a third housing 13. The second housing 12 is fastened to the first housing 11, and the third housing 13 is fastened to the second housing 12. The three components cooperate to form a cavity.

[0035] Specifically, the housing 11 has an adjustable slide 111, and the surface of the rear housing 351 is provided with a protrusion 353 adapted to the adjustable slide 111. When the adjustable nesting member 35 is placed in the cavity, the protrusion 353 is movably engaged in the adjustable slide 111. In this way, the rear housing 351 will move in the adjustable slide 111 when it is pushed. The adjustable slide 111 can cooperate with the eccentric adjustable wheel set 34 to realize the stable movement of the adjustable nesting member 35.

[0036] Furthermore, the pitch adjustment slide 111 has several tracks. An additional slide can be provided near the connection between the eccentric pitch adjustment wheel assembly 34 and the pitch adjustment nesting piece 35, which can increase the stability of the pitch adjustment nesting piece 35 when it moves.

[0037] like Figure 6 As shown, housing 2 12 has a limiting groove 121. The shape of the limiting groove 121 is adapted to the shape of the adjusting nest 35. The adjusting nest 35 is movably disposed in the limiting groove 121, which can limit the movement stroke of the adjusting nest 35 and prevent the massage head from moving excessively.

[0038] The housing 13 has a limiting hole 131, and the rotating rod 23 extends out of the limiting hole 131 and is movably disposed within the limiting hole 131. The limiting hole 131 allows the rotating rod 23 to move.
