Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical massage, and particularly relates to an adjustable massager and a massage pillow pad. Background Art

[0002] With the rapid development of society and the accelerating pace of life, more and more people need to obtain appropriate physical and mental relaxation after work. Therefore, in addition to exercise, massage is also a way to relax. There are various massagers on the market now, but most of them are not only expensive, but also relatively simple in massage methods, which seriously limits the areas that the massager can massage.

[0003] In view of the existing technology, most massagers massage around a central point or rely on eccentric wheels. This also causes the massage position of the massager to be restricted when the user uses the massager for massage. In the case of a single massage point and function, the range that the massager can massage is small, and the desired massage effect cannot be achieved. In addition, when the user wants to massage a specified position or perform reciprocating massage, the position of the massager needs to be continuously adjusted so that the massage mechanism in the massager is aligned with the place to be massaged to complete the massage function. Such a design causes great inconvenience to the user and fails to achieve the purpose of physical and mental relaxation. Summary of the Invention

[0004] Aiming at the above deficiencies existing in the prior art, the technical problem to be solved by the present invention is to provide an adjustable massager and a massage pillow pad that can increase the massage points of the massager, continuously change the massage position, can adjust the massage position according to the user, are simple to operate, and have a high degree of comfort.

[0005] The technical solution adopted by the present invention to solve its technical problems is to provide an adjustable massager, including: a box body, which is internally provided with a cavity, a movable plate that can move longitudinally is arranged in the cavity, and a guide shaft that is longitudinally fixed in the cavity and is located above the movable plate. A rotating sleeve is movably sleeved on the guide shaft, and the rotating sleeve is movably connected to the movable plate;

[0006] A driving assembly, which is arranged in the movable plate, and a driving member is arranged on the driving assembly. The driving member includes two working states: forward rotation and reverse rotation;

[0007] Symmetrically arranged massage mechanisms, which are movably arranged on the side far from the movable plate and are connected to the driving assembly. An extension part is arranged on the massage mechanism, and a fixed shaft located above the driving assembly is connected to the movable plate. The extension part is movably sleeved on the fixed shaft;

[0008] When the driving member rotates forward, it is used to drive the driving assembly to drive the massage mechanism to perform a cyclic motion; when the driving member rotates reversely, it is used to drive the driving assembly to drive the massage mechanism to perform a cyclic motion, and at the same time, the driving assembly can drive the moving plate to reciprocate along the direction of the guiding shaft.

[0009] In the above-mentioned adjustable massager, a guiding block is arranged inside the rotating sleeve, and a left-handed thread groove and a right-handed thread groove which are cross-connected are arranged on the guiding shaft, and the guiding block is movably arranged in the left-handed thread groove and the right-handed thread groove.

[0010] In the above-mentioned adjustable massager, the driving assembly includes a first gear transmission assembly and a second gear transmission assembly, and a one-way bearing is sleeved coaxially between the first gear transmission assembly and the second gear transmission assembly;

[0011] When the driving member rotates forward, it can drive the first gear transmission assembly to rotate, and the one-way bearing is used to limit the rotation of the second gear transmission assembly coaxially with the first gear transmission assembly; when the driving member rotates reversely, when the first gear transmission assembly rotates, it can drive the second gear transmission assembly to rotate through the rotation of the one-way bearing.

[0012] In the above-mentioned adjustable massager, the first gear transmission assembly includes a worm gear and a worm which are meshed with each other, and a pinion and a large gear I which are meshed with each other. One end of the worm is connected to the driving end of the driving member. The pinion is fixed on the worm gear and is coaxially arranged with the worm gear, and the rotating shaft of the large gear I is connected to the massage mechanism.

[0013] In the above-mentioned adjustable massager, the second gear transmission assembly is provided with a large gear II and a large gear III which are meshed with each other, and a bevel gear I and a bevel gear II which are meshed with each other. The large gear II is close to the bottom of the cavity and is coaxially arranged with the large gear I. The bevel gear I is fixed on one side of the large gear III close to the bevel gear II, and the bevel gear I is coaxially arranged with the large gear III. The bevel gear II is fixed at one end of the rotating sleeve away from the guiding block, and the bevel gear II is perpendicularly meshed with the bevel gear I.

[0014] In the above-mentioned adjustable massager, a waist-shaped hole is arranged on the extending portion, and the waist-shaped hole is movably sleeved on the fixed shaft.

[0015] In the above-mentioned adjustable massager, a mounting seat is installed on the moving plate. An installation plate that can be connected by a connecting member is provided on the mounting seat. An installation hole is formed between the installation plate and the mounting seat. The guide shaft penetrates through the installation hole, and the rotating sleeve is movably arranged in the installation hole.

[0016] In the above-mentioned adjustable massager, a cover plate is connected to the open end of the cavity. A guide groove is longitudinally provided on the cover plate. The rotating shafts of the large gear I and the fixed shaft are both inserted into the guide groove and extend outside the cover plate.

[0017] In the above-mentioned adjustable massager, the massage mechanism further includes an eccentric wheel and a massage plate. The eccentric wheel is movably connected to the extension portion, and the eccentric wheel is eccentrically connected to the rotating shaft of the large gear I; the massage plate is located above the eccentric wheel and the extension portion, and the massage plate is fixed to the extension portion.

[0018] The technical solution adopted by the present invention to solve its technical problems is to further propose a massage pillow cushion, including the above-mentioned adjustable massager, and further including: a cushion, the cushion is provided with a receiving cavity, and the box body is placed in the receiving cavity;

[0019] A connecting belt, one end of the connecting belt is connected to the top of the cushion;

[0020] A massage pillow, which is connected to the other end of the connecting belt, and the massage pillow is located above the receiving cavity and is movably abutted against the massage mechanism.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The massage mechanism is composed of an eccentric wheel, an extension portion and a massage plate. The waist-shaped hole on the extension portion is movably arranged on the fixed shaft, and the eccentric wheel is eccentrically connected to the rotating shaft of the large gear I. When the eccentric wheel rotates, it can drive the waist-shaped hole on the extension portion to move on the fixed shaft, thereby driving the massage plate to massage. This massage mechanism replaces the traditional single-rotation massage method of the eccentric wheel. At the same time, by using the extension portion to move on the fixed shaft, while increasing the massage points of the massager, it also makes the massage position constantly change, replacing the traditional single-position massage method and improving the comfort of the user during massage.

[0023] (2) Adjust the driving part to reverse. When the driving part drives the first gear transmission assembly to rotate and drives the massage mechanism to perform reciprocating motion massage at the same time, the first gear transmission assembly drives the second gear transmission assembly to rotate through a one-way bearing. Finally, the bevel gear I drives the bevel gear II to make the rotating sleeve perform longitudinal reciprocating motion along the direction of the guide shaft. Also, because the rotating sleeve is movably arranged in the mounting hole formed between the mounting seat on the moving plate and the mounting plate, when the rotating sleeve moves longitudinally, it can drive the entire moving plate to move. Thus, while the entire massage mechanism performs reciprocating motion massage, it can also achieve longitudinal movement, ensuring that the entire massager can adjust the massage position according to the user's needs, increasing the massage position range, and also enhancing the comfort of the massage.

[0024] (3) The first gear transmission assembly includes a worm and a worm gear that mesh with each other, and the worm is connected to the driving end of the driving part. The first gear transmission assembly is used to drive the massage mechanism to perform reciprocating cyclic massage motion. The meshing of the worm and the worm gear utilizes its self-locking property to prevent the massage mechanism from continuing to drive the gear to rotate due to the inertia generated during movement when the massage ends, thereby ensuring the safety of the entire massager and ensuring that the components are not easily damaged.

[0025] (4) The guide shaft is provided with a left-handed thread groove and a right-handed thread groove that are cross-connected. The guide block arranged in the rotating sleeve is movably arranged in the left-handed thread groove and the right-handed thread groove. Ensure that when the guide block longitudinally moves to the limit position in the left-handed thread groove, it can directly move from the limit position of the left-handed thread groove to the right-handed thread groove, thereby realizing the longitudinal reciprocating motion of the entire moving plate, that is, driving the massage mechanism to perform longitudinal reciprocating motion, adjusting the massage position while increasing the range of massageable areas, facilitating the operation of the user, and bringing better comfort to the user.

[0026] (5) Connect a connecting belt above the cushion and a massage pillow cushion connected to the connecting belt. The massage pillow cushion is movably abutted against the massage plate. That is, when the user wants to massage closely, the massage pillow cushion can be flipped to one side of the cushion through the connecting belt. Similarly, when the user wants to increase the comfort of the cushion, the massage pillow cushion can be placed on the opening of the accommodation cavity and abutted against the massage plate, increasing the comfort of relying on the massager while also achieving the massage effect.

[0041] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0042] Embodiment 1

[0043] As Figures 1 to 2 shown, an adjustable massager, characterized in that it comprises: a box body 100 with an inner cavity 110 therein, a movable plate 120 longitudinally movable in the inner cavity 110, and a guide shaft 130 longitudinally fixed in the inner cavity 110 above the movable plate 120. A rotating sleeve 140 is movably sleeved on the guide shaft 130, and the rotating sleeve 140 is movably connected to the movable plate 120; a driving assembly 200 disposed in the movable plate 120, with a driving member 210 provided on the driving assembly 200, and the driving member 210 includes two working states of forward rotation and reverse rotation; symmetrically arranged massage mechanisms 300 movably disposed on one side away from the movable plate 120 and connected to the driving assembly 200. An extension portion 310 is provided on the massage mechanism 300, and a fixed shaft 121 located above the driving assembly 200 is connected to the movable plate 120. The extension portion 310 is movably sleeved on the fixed shaft 121; when the driving member 210 rotates forward, it is used to drive the driving assembly 200 to drive the massage mechanism 300 to perform a cyclic motion; when the driving member 210 rotates in reverse, it is used to drive the driving assembly 200 to drive the massage mechanism 300 to perform a cyclic motion, and at the same time, the driving assembly 200 can drive the movable plate 120 to perform a reciprocating motion along the direction of the guide shaft 130.

[0044] To achieve the purpose of increasing the massage points and expanding the massage range of the present invention, an extension portion 310 is provided on the massage mechanism 300, and the extension portion 310 is movably sleeved on the fixed shaft 121. When the driving member 210 drives the massage mechanism 300 to perform a cyclic motion, the massage range is increased. At the same time, the guide shaft 130 is longitudinally fixed in the inner cavity 110 of the box body 100 and is connected to the movable plate 120 by means of the rotating sleeve 140, that is, the longitudinal reciprocating motion of the rotating sleeve 140 on the guide shaft 130 is used to achieve the longitudinal reciprocating motion of the movable plate 120 in the inner cavity 110. It should be noted that the driving assembly 200 and the massage assembly in the present invention are both provided on the movable plate 120, and the longitudinal movement of the movable plate 120 is relied on to drive the driving assembly 200 and the massage assembly to achieve longitudinal movement, thereby increasing the massage range and enabling self-adjustment according to the user's own situation to improve the user's comfort. In addition, two working states are provided on the driving member 210. In the case where the driving member 210 rotates forward, the driving member 210 only drives the driving assembly 200 to drive the massage mechanism 300 to perform a reciprocating motion, while in the case where the driving member 210 rotates in reverse, the driving member 210 can simultaneously drive the massage mechanism 300 to perform a reciprocating motion and the movable plate 120 to perform a longitudinal reciprocating motion along the direction of the guide shaft 130. This design ensures that the user can self-adjust the height of the massage mechanism 300, expands the working range of the massage mechanism 300, and improves the comfort of the massage.

[0045] AsFigures 2 to 5 As shown, a guiding block 141 is provided inside the rotating sleeve 140, and a left-handed thread groove 131 and a right-handed thread groove 132 which are cross-connected are provided on the guiding shaft 130. The guiding block 141 is movably arranged inside the left-handed thread groove 131 and the right-handed thread groove 132.

[0046] First, in order to realize the longitudinal reciprocating movement of the moving plate 120 in the present invention, a left-handed thread groove 131 and a right-handed thread groove 132 which are cross-connected are provided on the guiding shaft 130. To ensure the stability of the moving plate 120 during longitudinal movement, a guiding block 141 is provided inside the rotating sleeve 140. The guiding block 141 is movably arranged inside the left-handed thread groove 131 and the right-handed thread groove 132. When the rotating sleeve 140 rotates on the guiding shaft 130, the guiding block 141 will reciprocate along the track of the left-handed thread groove 131 or the right-handed thread groove 132. It should be noted that the design principle of the left-handed thread groove 131 and the right-handed thread groove 132 is similar to the working principle of a bidirectional lead screw. By machining two threads with different helix directions on one lead screw, that is, one right-handed thread and one left-handed thread. Different from the nut screwed on its upper end, the guiding shaft 130 in the present invention is fixed inside the cavity 110 of the box body 100, and the guiding block 141 inside the rotating sleeve 140 moves in two thread grooves with different helix directions. While the rotating sleeve 140 rotates, it drives the moving plate 120 to reciprocate along the direction of the guiding shaft 130. The following is an example for illustration. If the guiding block 141 is located inside the left-handed thread groove 131 and moves downward along the longitudinal direction of the guiding shaft 130 to the end of the left-handed thread groove 131 when the rotating sleeve 140 rotates, because the left-handed thread groove 131 and the right-handed thread groove 132 are connected end to end, the guiding block 141 inside the rotating sleeve 140 will slide from the end of the left-handed thread groove 131 to the starting point of the right-handed thread groove 132, so as to ensure that the guiding block 141 continues to move upward along the longitudinal direction of the guiding shaft 130 by relying on the right-handed thread groove 132. Similarly, when the guiding block 141 moves to the end of the right-handed thread groove 132, it will continue to reciprocate along the guiding shaft 130 from the starting point of the left-handed thread groove 131. As for the starting point and the end point of the left-handed thread groove 131 and the right-handed thread groove 132, they can be determined by oneself. In short, the guiding block 141 inside the rotating sleeve 140 moving in the left-handed thread groove 131 and the right-handed thread groove 132 is the main technical means to realize the longitudinal reciprocating movement of the moving plate 120, and also the design concept to increase the massage range. With this function, the user can independently adjust the massager, improving the comfort of the massage.

[0047] Such as Figures 2 to 7As shown in the figure, the driving assembly 200 includes a first gear transmission assembly 220 and a second gear transmission assembly 240, and a one-way bearing 250 is sleeved coaxially between the first gear transmission assembly 220 and the second gear transmission assembly 240; when the driving member 210 rotates forward, it can drive the first gear transmission assembly 220 to rotate, and the one-way bearing 250 is used to limit the rotation of the second gear transmission assembly 240 coaxial with the first gear transmission assembly 220; when the driving member 210 rotates reversely, when the first gear transmission assembly 220 rotates, it can drive the second gear transmission assembly 240 to rotate through the rotation of the one-way bearing 250.

[0048] The massager in the present invention can achieve three different working states, and the specific analysis is as follows: The first working state:

[0049] When the driving member 210 rotates forward, the driving member 210 drives the first gear transmission assembly 220 to move. Since a one-way bearing 250 is provided at the connecting shaft of the first gear transmission assembly 220 and the second gear transmission assembly 240, and the one-way bearing 250 is a bearing that can rotate freely in one direction and is locked in the other direction, the first gear transmission assembly 220 will not drive the second gear transmission mechanism to move when rotating, and thus will not realize the movement of the massage mechanism 300 along the longitudinal direction of the guide shaft 130, and can only realize the function of driving the massage assembly to reciprocate by the first gear transmission assembly 220.

[0050] The second working state:

[0051] When the driving member 210 rotates reversely, at this time, the one-way bearing 250 rotates synchronously with the rotating shaft of the large gear I and has a driving force, that is, when the driving member 210 drives the first gear transmission assembly 220 to rotate, the first gear transmission assembly 220 can rely on the one-way bearing 250 to drive the second gear transmission assembly 240 to rotate, and further simultaneously realize that the first gear transmission assembly 220 drives the massage assembly to reciprocate, and when the second gear driving assembly 200 drives the rotating sleeve 140 to rotate, it drives the moving plate 120 to reciprocate along the longitudinal direction of the guide shaft 130.

[0052] The third working state:

[0053] According to the user's needs, the moving plate 120 does not necessarily have to be at the top or bottom of the cavity 110 of the box body 100. That is, the position of the moving plate 120 in the cavity 110 determines the massage position of the massage mechanism 300. Therefore, the user can directly reverse the driving member 210. When the moving plate 120 moves to the middle or other positions of the cavity 110 of the box body 100, the reverse state of the driving member 210 is adjusted to the forward rotation state. At this time, the second gear transmission assembly will not rotate with the rotation of the first gear transmission assembly due to the one-way bearing, that is, the moving plate 120 stops moving longitudinally along the direction of the guide shaft, and the massage mechanism 300 can stay at the position when the driving member 210 is reversely closed. Then, the massage mechanism 300 can perform reciprocating motion again at the position required by the user. This working state also enables the user to adjust the massage mechanism 300 to the required massage position according to their own needs and then perform reciprocating motion, which is convenient for the user to adjust the massage position of the massager and improves the comfort brought by the massager to the user.

[0054] The first gear transmission assembly 220 includes a worm wheel 221 and a worm 222 that mesh with each other, and a pinion 223 and a large gear I 224 that mesh with each other. One end of the worm 222 is connected to the driving end of the driving member 210. The pinion 223 is fixed on the worm wheel 221 and is coaxially arranged with the worm wheel 221. The rotating shaft of the large gear I 224 is connected to the massage mechanism 300.

[0055] To ensure that the driving member 210 can drive the massage mechanism 300 to perform reciprocating motion through the first gear driving assembly 200 when it rotates forward, a worm wheel 221 and a worm 222 that mesh with each other are provided in the first gear transmission assembly 220. One end of the worm 222 is connected to the output end of the driving member 210. When the driving member 210 is in the forward rotation working state, the driving end of the driving member 210 drives the worm 222 to rotate simultaneously. The worm 222 drives the worm wheel 221 meshing with it to rotate. Also, because the pinion 223 is fixed on the worm wheel 221 and is coaxially arranged with the worm wheel 221, when the worm wheel 221 rotates, it will drive the pinion 223 to rotate together, and then drive the large gear I 224 to rotate through the pinion 223. The massage mechanism 300 is connected to the rotating shaft of the large gear I 224. Therefore, when the large gear I 224 rotates, the massage mechanism 300 starts to enter the working state with the rotation of the large gear I 224. It should be noted that the worm wheel 221 is located on one side of the radial direction of the worm 222. On the other side of the radial direction of the worm 222, a support gear 230 is meshed. By meshing the worm wheel 221 and the support gear 230 on both sides of the worm 222, the tendency of the worm 222 to move downward during rotation is avoided, and the stability of the worm 222 during rotation is improved.

[0056] On the second gear transmission assembly 240, there are a large gear II 241 and a large gear III 242 that mesh with each other, as well as a bevel gear I 243 and a bevel gear II 244 that mesh with each other. The large gear II 241 is close to the bottom of the cavity 110 and is coaxially arranged with the large gear I 224. The bevel gear I 243 is fixed on one side of the large gear II 241 close to the bevel gear II 244, and the bevel gear I 243 is coaxially arranged with the large gear III 242. The bevel gear II 244 is fixed at one end of the rotating sleeve 140 away from the guide block 141, and the bevel gear II 244 meshes perpendicularly with the bevel gear I 243.

[0057] In the working state where the driving member 210 rotates in reverse, the first gear transmission assembly 220 can drive the second gear transmission assembly 240 to rotate through the one-way bearing 250. It should be noted that when the driving member 210 rotates in reverse, the driving member 210 drives the first gear transmission assembly 220 to work normally, that is, the massage mechanism 300 is in a working state regardless of whether the driving member 210 is in a forward or reverse working state. Therefore, when the driving member 210 rotates in reverse, it drives the first gear transmission assembly 220 to move, and relies on the first gear transmission assembly 220 to drive the massage mechanism 300 to perform reciprocating motion. At the same time, when the large gear I 224 in the first gear assembly is working, the one-way bearing 250 starts to work when the driving member 210 rotates in reverse, that is, the large gear I 224 drives the large gear II 241 arranged coaxially with it to rotate together. When the large gear II 241 rotates, it drives the large gear III 242 to rotate. Because the bevel gear I 243 is coaxially arranged with the large gear III 242, when the large gear III 242 rotates, it drives the bevel gear I 243 to rotate synchronously. The bevel gear I 243 is used to drive the bevel gear II 244 meshing with it to rotate. Also, because the bevel gear II 244 is connected to the rotating sleeve 140 as described above, and the bevel gear I 243 meshes perpendicularly with the bevel gear II 244, when the bevel gear I 243 drives the bevel gear II 244 to rotate, it will drive the rotating sleeve 140 to rotate together, thereby realizing the longitudinal reciprocating motion of the guide block 141 in the rotating sleeve 140 along the direction of the guide shaft 130, driving the longitudinal reciprocating motion of the moving plate 120, that is, the longitudinal reciprocating motion of the massage mechanism 300, and achieving the effect of increasing the massage position of the massage mechanism 300 and making the massage position adjustable.

[0058] In addition, the following is an explanation of the installation method of the one-way bearing 250: Since the large gear I 224 and the large gear II 241 are coaxially arranged, in order to ensure that the large gear II 241 will not rotate due to the rotation of the large gear I 224 when the driving member 210 rotates forward, and when the driving member 210 rotates in reverse, the large gear II 241 will rotate coaxially with the large gear I 224. Therefore, a one-way bearing 250 is sleeved on the coaxial shaft of the large gear I 224. The one-way bearing 250 is movably abutted against the large gear I 224 and is close to the side of the large gear II 241. A through hole is provided on the large gear II 241, and the through hole is sleeved on the one-way bearing 250, so as to realize the switching between the two states of the stop and rotation of the large gear II 241 by using the one-way bearing 250.

[0059] As Figures 2 to 10 shown, a waist-shaped hole 311 is provided on the extension part 310, and the waist-shaped hole 311 is movably sleeved on the fixed shaft 121; the massage mechanism 300 further includes an eccentric wheel 320 and a massage plate 330. The eccentric wheel 320 is movably connected to the extension part 310, and the eccentric wheel 320 is eccentrically connected to the rotating shaft of the large gear I 224; the massage plate 330 is located above the eccentric wheel 320 and the extension part 310, and the massage plate 330 is fixed on the extension part 310.

[0060] It is pointed out above that the extension part 310 can increase the massage points and expand the massage position of the massage mechanism 300. The principle of this design is that when the driving member 210 drives the first gear transmission assembly 220 to rotate, the large gear I 224 in the first gear transmission assembly 220 drives the eccentrically connected eccentric wheel 320 to rotate together. While the eccentric wheel 320 makes an elliptical motion along the eccentric shaft, because the eccentric wheel 320 is movably connected to the extension part 310, the rotation of the eccentric wheel 320 will drive the extension part 310 to rotate together. The waist-shaped hole 311 on the extension part 310 is movably arranged on the fixed shaft 121. Therefore, when the eccentric shaft makes an elliptical motion, the waist-shaped hole 311 on the extension part 310 will make a reciprocating motion along with the fixed shaft 121, that is, the elliptical motion formed by the eccentric rotation of the eccentric wheel 320 plus the sector motion of the waist-shaped hole 311 on the extension part 310 relying on the fixed shaft 121 forms a new massage method. This massage method replaces the working posture of the traditional single eccentric wheel 320 fixed massage. While increasing the massage points, the elliptical motion of the eccentric wheel 320 and the sector motion of the extension part 310 make the massage method closer to the posture during manual massage, expand the massage range, and are beneficial to improving the comfort of the user.

[0061] A mounting seat 122 is installed on the moving plate 120. An installation plate 123 that can be connected by a connecting piece is provided on the mounting seat 122. An installation hole 124 is formed between the installation plate 123 and the mounting seat 122. The guide shaft 130 passes through the installation hole 124, and the rotating sleeve 140 is movably arranged in the installation hole 124.

[0062] As pointed out above, the rotating sleeve 140 is connected to the moving plate 120. The longitudinal movement of the moving plate 120 is driven by the guiding block 141 on the rotating sleeve 140 moving longitudinally along the direction of the guiding shaft 130. Here, it should be noted that to ensure that the connection between the rotating sleeve 140 and the moving plate 120 does not affect the rotation effect of the rotating sleeve 140 itself, a mounting seat 122 is provided on the moving plate 120. The mounting hole 124 formed by the mounting seat 122 and the mounting plate 123 is used to place the rotating sleeve 140. The diameter of the mounting hole 124 formed here is slightly larger than the diameter of the rotating sleeve 140. In this way, the rotating sleeve 140 can rotate freely within the mounting hole 124. The guiding shaft 130 passes through the mounting hole 124 and is fixed within the cavity 110. The rotating sleeve 140 also passes through the mounting hole 124 and is rotatably arranged within the mounting hole 124. Therefore, under the action of the connecting piece, the mounting plate 123 is used to connect the rotating sleeve 140 and the mounting seat 122 together. When the rotating sleeve 140 rotates, the connected moving plate 120 is driven to move. This is also the way to drive the moving plate 120 to move longitudinally along the guiding shaft 130 by using the rotation of the rotating sleeve 140. In addition, the connecting piece described in the text can be a bolt connection, a screw connection or other connection methods.

[0063] A cover plate 150 is connected to the open end of the cavity 110. A guiding groove 151 is longitudinally provided on the cover plate 150. The rotating shaft of the large gear I 224 and the fixed shaft 121 are both inserted into the guiding groove 151 and extend outside the cover plate 150.

[0064] To ensure that the moving plate 120 does not deviate when moving longitudinally along the direction of the guiding shaft 130, a guiding groove 151 is longitudinally provided on the cover plate 150 at the open end of the cavity 110. The massage mechanism 300 is all arranged above the cover plate 150. When the driving member 210 reverses and the moving plate 120 moves longitudinally, the rotating shaft of the large gear I 224 and the fixed shaft 121 that pass through the guiding groove 151 and extend outside the cover plate 150 can move reciprocally along the direction of the guiding groove 151 with the longitudinal reciprocating movement of the moving plate 120. In addition, the cover plate 150 on the cavity 110 also plays a certain role in dust prevention; in addition, to further ensure the stability of the moving plate 120 when moving, a clamping groove 125 is opened at the bottom of the moving plate 120, and a corresponding clamping block 111 is opened at the bottom of the cavity 110. The clamping block 111 is clamped within the clamping groove 125. At the same time, a limiting block 126 is provided on one side of the moving plate 120, and a limiting groove 112 is provided on one side of the moving plate 120 that moves within the cavity 110. The limiting block 126 is movably clamped within the limiting groove 112. These methods can all be used to ensure that the moving plate 120 does not deviate when moving longitudinally along the guiding shaft 130 and has good stability.

[0065] In addition, it should be noted that the driving member 210 described above is provided with two driving ends. One of the driving ends is only connected to the first gear transmission assembly 220 and one of the massage mechanisms 300, while the other driving end is connected to the first gear transmission assembly 220, the massage mechanism 300, the second gear transmission assembly 240, and the installation of the moving plate 120 and the guide shaft 130. The installation of the second gear driving assembly 200 and the moving plate 120 and the guide shaft 130 is not symmetrically arranged because the purpose of the design of the second gear driving assembly 200 is to realize the longitudinal movement of the moving plate 120 to complete the longitudinal reciprocating movement of the massage mechanism 300. The stability of the moving plate 120 during movement has been solved above, so there is no need to set up the same mechanism to drive the longitudinal movement of the moving plate 120, which greatly saves the use of materials and reduces the manufacturing cost.

[0066] Embodiment 2

[0067] As Figures 1 to 10 shown, the present invention also provides a massage pillow cushion 430, which includes an adjustable massager according to Embodiment 1. Among them, it further includes: a cushion 400, the cushion 400 is provided with a receiving cavity 410, and the box body 100 is placed in the receiving cavity 410; a connecting belt 420, one end of the connecting belt 420 is connected to the top of the cushion 400; a massage pillow cushion 430, which is connected to the other end of the connecting belt 420, and the massage pillow cushion 430 is located above the receiving cavity 410 and is movably abutted against the massage mechanism 300.

[0068] During the process of the massager realizing the massage function, in order to improve the comfort of the user, the box body 100 is placed in the receiving cavity 410 by using the receiving cavity 410 provided on the cushion 400. To further ensure the convenience of the user when using the massager, convex portions 440 are symmetrically provided on both sides of the backrest. The convex portions 440 are arc-shaped and inclined. The top of the backrest is connected with a connecting belt 420, and the other end of the connecting belt 420 is connected to a massage pad. When the user wants to massage closely, only need to turn the massage pillow cushion 430 to one side of the cushion 400 through the connecting belt 420, then the massage position can be attached to the massage plate 330 for massage; when the user wants to further improve the comfort of the massage, only need to turn the massage pad to above the massage, the user leans on the massage pad, and the massage position is placed on the convex portions 440 with arc shapes on both sides, which not only increases the comfort but also has different massage effects. It should be noted that the force effect is significantly different when massaging without the massage pad compared to when the user leans on the massage pad for massage, and the user can also adjust the required massage force in this way.

[0069] As Figures 1 to 10 shown, the working principle of the adjustable massager and the massage pillow cushion is as follows:

[0070] When the driving member 210 is adjusted to the forward rotation state, the driving member 210 will drive the first gear transmission assembly 220 to rotate. While the first gear transmission assembly 220 is rotating, it will drive the massage mechanism 300 connected to the first gear transmission assembly 220 to rotate, so that the massage plate 330 makes a reciprocating motion. When the user needs to adjust the massage position, the driving member 210 can be adjusted to the reverse rotation state. Relying on the one-way bearing 250, when the driving member 210 drives the first gear transmission assembly 220 to rotate, it will drive the second gear transmission assembly 240 connected to the first gear transmission assembly 220 to rotate together. While the second gear transmission assembly 240 is rotating, when the bevel gear I 243 drives the bevel gear II 244 to rotate, the rotating sleeve 140 connected to the bevel gear II 244 will also rotate together. Also, because the guiding block 141 inside the rotating sleeve 140 will slide on the guiding shaft 130 when the rotating sleeve 140 rotates, and the rotating sleeve 140 is movably connected to the moving plate 120, so when the rotating sleeve 140 rotates, it drives the moving plate 120 to make a reciprocating motion in the longitudinal direction, and finally realizes the longitudinal reciprocating motion of the massage mechanism 300.

[0071] According to the user's own needs, the massage pillow 430 can be flipped onto the massage mechanism 300, which not only improves the massage comfort, but also enables the user to experience different massage intensities using the massage pillow 430.

[0072] The driving member 210 described in the text can be a stepping motor, a servo motor or other driving devices.
