[0040] The present utility model provides a massager.

[0041] Please refer to Figure 1 , Figure 2 , in an embodiment of the present utility model, the massager includes a massage assembly 100 and a housing 200. The massage assembly 100 is installed in the housing 200, and the massage assembly 100 includes:

[0042] A first massage head 110 and a movable arm 120. The movable arm 120 has a first end 121 and a second end 122. The first massage head 110 is provided at the second end 122. The movable arm 120 is movably installed in the housing 200 and can drive the first massage head 110 to move, and the massage action is completed through the movement of the first massage head 110.

[0043] The mounting shaft 170 and the first driving structure 130 are installed. The mounting shaft 170 is slidably connected to the movable arm 120, and the sliding direction is along the length direction of the movable arm 120. The first driving structure 130 is drivingly connected to the movable arm 120. The first driving structure 130 is used to swing the second end 122 along the first trajectory. When the second end 122 of the movable arm 120 swings along the first trajectory, the first massage head 110 can also swing along the first trajectory, thereby completing the massage action. At this time, the first massage head 110 can swing along the first trajectory, so that the massage range of the first massage head 110 is larger than that of the massage head for fixed-point massage, and thus the technical problems existing in the prior art can be solved. At the same time, when the second end 122 of the movable arm 120 swings along the first trajectory, the first end 121 of the movable arm 120 swings along the second trajectory, and the mounting shaft 170 reciprocally slides relative to the movable arm 120. At this time, both the first end 121 and the second end 122 of the movable arm 120 can move. In this way, when the second end 122 moves, its range can increase. Compared with the structure in which the first end 121 of the movable arm 120 cannot move, as the movement range of the second end 122 increases, the range of the first trajectory also increases. At this time, when the first massage head 110 massages along the first trajectory, the massage range of the first massage head 110 can also increase, realizing a larger range of massage, and thus solving the technical problems existing in the prior art.

[0044] In one embodiment, please refer to Figure 2 , the first driving structure 130 includes a first rotating wheel 131 and a first eccentric shaft 132 provided on the first rotating wheel 131. The first eccentric shaft 132 is rotatably connected to the movable arm 120. When the first rotating wheel 131 rotates, it can drive the first end 121 to swing along the first trajectory through the first eccentric shaft 132. In this embodiment, the first rotating wheel 131 can be driven directly or indirectly. When directly driven, the output end of the motor directly drives the first rotating wheel 131 to rotate. When indirectly driven, the motor indirectly drives the first rotating wheel 131 to rotate through a transmission belt, or a transmission gear, or a chain.

[0045] In one embodiment, please refer to Figure 2 、 Figure 3, the first driving structure 130 further includes a guiding structure 133 and a first driving groove 1311 formed in the first rotating wheel 131. The first eccentric shaft 132 is slidably disposed in the guiding structure 133 and passes through the first driving groove 1311. When the first rotating wheel 131 rotates, the first driving groove 1311 can drive the first eccentric shaft 132 to slide along the guiding structure 133, and at the same time, the first eccentric shaft 132 reciprocates within the first driving groove 1311. Further, since the first eccentric shaft 132 is disposed through the first driving groove 1311, the connection line between the axis of the first eccentric shaft 132 and the rotation axis of the first rotating wheel 131 is parallel to the length extension direction of the first driving groove 1311 or is disposed at a certain angle. When the connection line is parallel to the extension direction or at a non-90-degree angle, the width of the first driving groove 1311 is adapted to the diameter of the first eccentric shaft 132. When the angle is 90 degrees, the width of the first driving groove 1311 is greater than the diameter of the first eccentric shaft 132. At this time, in order to enable the first driving groove 1311 to drive the first eccentric shaft 132 to slide along the guiding structure 133, a transmission member is further provided between the first driving groove 1311 and the first eccentric shaft 132. The transmission member is used to transmit the power of the first driving groove 1311 to the first eccentric shaft 132 so that the first eccentric shaft 132 slides along the guiding structure 133. That is, the first driving groove 1311 pushes the first eccentric shaft 132 to slide along the guiding structure 133 through the transmission member, and the transmission member can be a rod-shaped structure. In this embodiment, the first rotating wheel 131 drives the first eccentric shaft 132 to rotate, and the movement trajectory of the first eccentric shaft 132 is affected by the guiding structure 133. According to different shapes of the guiding structure 133, the movement trajectory of the first eccentric shaft 132 is also different.

[0046] In one embodiment, please refer to Figure 2 、 Figure 3, the guiding structure 133 is configured as an elliptical guide groove, and the first eccentric shaft 132 slides along the elliptical guide groove. At this time, the moving track of the first eccentric shaft 132 is elliptical. At the same time, in this embodiment, when the moving track of the first eccentric shaft 132 is elliptical, when the first eccentric shaft 132 moves to different positions, affected by the elliptical contour, the moving speed corresponding to the first eccentric shaft 132 will change, so that the second end 122 of the movable arm 120 has different swinging speeds, and further enables the first massage head 110 to achieve different massage effects when massaging. However, this design is not limited to this. In other embodiments, the guiding structure 133 can also be configured as guide grooves or guide rails of other shapes, such as a lotus-shaped guide rail, a quadrilateral guide rail, etc. When the guiding structure 133 is configured as a quadrilateral guide rail, in order to facilitate the first eccentric shaft 132 to pass through the sharp corners of the quadrilateral guide rail, a bearing can be sleeved outside the first eccentric shaft 132 to reduce the friction between the first eccentric shaft and the sharp corners of the quadrilateral guide rail so that the first eccentric shaft 132 can pass through. However, this design is not limited to this. In other embodiments, when the guiding structure 133 is configured as a quadrilateral guide rail, the sharp corners of the quadrilateral guide rail are processed into arcs so that the first eccentric shaft 132 can pass through the sharp corners of the quadrilateral guide rail.

[0047] In one embodiment, please refer to Figure 2 , Figure 3 , the massager is provided with a base 210 and a cover body. The base 210 is provided with an elliptical guide groove, and the cover body is provided with an elliptical hole 221. One end of the first eccentric shaft 132 is slidably arranged in the elliptical guide groove, and the other end passes through the first driving groove 1311 and is slidably arranged in the first driving groove 1311; when the first eccentric shaft 132 slides along the elliptical guide groove, the first rotating wheel 131 can limit the first eccentric shaft 132 in the elliptical guide groove. In this embodiment, the first eccentric shaft 132 needs to be installed into the elliptical guide groove first, and then the first rotating wheel 131 is installed. When installing the first rotating wheel 131, the first eccentric shaft 132 passes through the first driving groove 1311. At this time, when the first eccentric shaft 132 slides along the elliptical guide groove, the first rotating wheel 131 can limit it in the elliptical guide groove to prevent it from disengaging from the elliptical guide groove.

[0048] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the massager further includes a second rotating wheel 140. The movable arm 120 is provided with a second driving groove 123 corresponding to the mounting shaft 170. The second driving groove 123 extends along the length direction of the movable arm 120, and the mounting shaft 170 is slidably inserted into the second driving groove 123;

[0049] The mounting shaft 170 is fixedly arranged on the housing 200 or the second rotating wheel 140. When the mounting shaft 170 is fixed on the second rotating wheel 140, the mounting shaft 170 is coaxially arranged with the second rotating wheel 140. At this time, when the third rotating wheel 161 rotates, the mounting shaft 170 can remain stationary relative to the second rotating wheel 140, or can rotate with the second rotating wheel 140, that is, rotate on its own axis. At this time, the mounting shaft 170 reciprocally slides relative to the second driving groove 123.

[0050] However, the present design is not limited to this. In other embodiments, it is arranged on the second rotating wheel 140 and is eccentrically arranged relative to the rotation axis of the second rotating wheel 140. When the mounting shaft 170 is eccentrically arranged on the second rotating wheel 140 and the second rotating wheel 140 rotates, the mounting shaft 170 can rotate around the rotation axis of the second rotating wheel 140. At this time, the mounting shaft 170 drives the movable arm 120 to move. At the same time, in this embodiment, the mounting shaft 170 reciprocally slides in the first driving groove 1311.

[0051] However, the present design is not limited to this. In other embodiments, the movable arm 120 is provided with a guide rail corresponding to the mounting shaft 170. The mounting shaft 170 is slidably arranged in the guide rail (not shown), and the mounting shaft 170 is rotatably connected between the housing 200 or the second rotating wheel 140. At this time, when the movable arm 120 moves, when the first end 121 swings along the second trajectory, the guide rail can move on the guide shaft so that the mounting shaft 170 moves relative to the guide rail. Since the mounting shaft 170 is rotatably connected between the housing 200 or the second rotating wheel 140, when the mounting shaft 170 moves with the movable arm 120 at this time, the guide shaft can rotate correspondingly relative to the housing 200 or the second rotating wheel 140.

[0052] In one embodiment, please refer to Figure 2 , the second rotating wheel 140 is in transmission connection with the first rotating wheel 131, and the transmission connection between the second rotating wheel 140 and the first rotating wheel 131 can be through direct connection or indirect connection. When the second rotating wheel 140 and the first rotating wheel 131 are directly connected, the second rotating wheel 140 and the first rotating wheel 131 can be configured as transmission gears, and the direct connection is completed through the meshing of the two transmission gears. When the second rotating wheel 140 and the first rotating wheel 131 are indirectly connected, the second rotating wheel 140 and the first rotating wheel 131 can be indirectly connected through a transmission belt, a chain, or a transmission gear. Since the second rotating wheel 140 and the first rotating wheel 131 are in transmission connection, at this time, driving one of them can cause the other to rotate accordingly. However, the present design is not limited to this. In other embodiments, the second rotating wheel 140 may not be in transmission connection with the first rotating wheel 131, and the second rotating wheel 140 can be driven to rotate indirectly or directly by a motor. For the method of indirectly or directly driving the second rotating wheel 140 by the motor, the cooperation method between the first rotating wheel 131 and the motor described above can be referred to.

[0053] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , the massager further includes a second massage head 150 and a second driving structure 160, and the second driving structure 160 is used to drive the second massage head 150 to rotate. In this embodiment, the manner in which the second driving structure 160 drives the second massage head 150 to rotate can be direct driving or indirect driving. For direct driving, the second driving structure 160 is configured as a motor, and the output end of the motor directly drives the second massage head 150 to rotate. For indirect driving, the second driving structure 160 can indirectly drive the second massage head 150 to rotate through a transmission belt, or transmission gears, or a chain by the motor.

[0054] In one embodiment, please refer to Figure 5 , Figure 6 , the second driving structure 160 can also adopt the following structure. The second driving structure 160 includes a third rotating wheel 161 and a transmission structure 162, and the second massage head 150 is installed on the transmission structure 162; when the third rotating wheel 161 rotates, the third rotating wheel 161 can drive the second massage head 150 to rotate through the transmission structure 162. In this embodiment, the manner of driving the third rotating wheel 161 to rotate can be direct driving or indirect driving. When directly driving, the output end of the motor directly drives the third rotating wheel 161 to rotate. At this time, the third rotating wheel 161 drives the transmission structure 162 to rotate, so that the transmission structure 162 drives the second massage head 150 to rotate. When indirectly driving, the motor indirectly drives the transmission structure 162 through a transmission belt, or transmission gears, or a chain, so that the transmission structure 162 drives the second massage head 150 to rotate. At the same time, in this embodiment, the transmission structure 162 can be a connecting rod or a rotating wheel structure, which is not limited herein. When the transmission structure 162 is configured as a connecting rod, one end of the connecting rod is connected to the second massage head 150, and the other end is connected to the third rotating wheel 161. When the transmission structure 162 is configured as a rotating wheel structure, the second massage head 150 is installed on the rotating wheel structure, and the transmission wheel structure is in transmission connection with the third rotating wheel 161.

[0055] In one embodiment, please refer to Figure 5 , Figure 6 , the third rotating wheel 161 is provided with an eccentric hole 1611;

[0056] The transmission structure 162 includes a transmission rod 1621, a spherical part 1622, a universal joint seat 1623 and a universal joint fixing cover 1624 provided on the transmission rod 1621. The universal joint fixing cover 1624 is used to restrict the spherical part 1622 to move within the universal joint seat 1623. One end of the transmission rod 1621 is movably inserted into the eccentric hole 1611, and the second massage head 150 is installed at the other end of the transmission rod 1621. When the first rotating wheel 131 rotates, the eccentric hole 1611 drives the transmission rod 1621. One end of the transmission rod 1621 inserted into the eccentric hole 1611 rotates following the eccentric hole 1611. Under the action of the spherical part 1622, the end of the transmission rod 1621 connected to the second massage head 150 can rotate. At this time, the transmission rod 1621 can make the second massage head 150 rotate, and further make the second massage head 150 perform massage.

[0057] In one embodiment, please refer to Figure 5 , Figure 6 , the first rotating wheel 131 and the third rotating wheel 161 are in transmission connection. The first rotating wheel 131 and the third rotating wheel 161 can be directly in transmission connection or indirectly in transmission connection. When the first rotating wheel 131 and the third rotating wheel 161 are directly in transmission connection, both the first rotating wheel 131 and the third rotating wheel 161 are configured as transmission gears. The power transmission between the third rotating wheel 161 and the first rotating wheel 131 is completed by the meshing of the two transmission gears. At the same time, when the second rotating wheel 140 is also configured as a transmission gear and the first rotating wheel 131 and the second rotating wheel 140 are directly in transmission connection, when the number of teeth of the second rotating wheel 140 and the third rotating wheel 161 is designed to be the same, the movements of the first massage head 110 and the second massage head 150 will be in the same frequency, and the effect of synchronous kneading can be achieved. If the number of teeth is designed inconsistently, that is, the movements of the first massage head 110 and the second massage head 150 are not in the same frequency, and they knead once when moving to a certain fitting point, a different kneading effect will be shown. When the first rotating wheel 131 and the third rotating wheel 161 are indirectly in transmission connection, the first rotating wheel 131 and the third rotating wheel 161 can be indirectly transmitted through a transmission belt, or a chain, or a transmission gear. That is to say, the power between the first rotating wheel 131 and the third rotating wheel 161 can be transmitted through a transmission belt, or a chain, or a transmission gear.

[0058] In one embodiment, please refer to Figure 1 , the massage assembly 100 is provided in two groups;

[0059] The massager further includes a drive shaft 300. The two massage components 100 are symmetrically arranged with respect to the drive shaft 300. The drive shaft 300 is used to drive the first drive structure 130 in the two massage components 100, that is, to drive the first rotating wheel 131 in the first drive structure 130 to rotate. At this time, the first rotating wheel 131 is in transmission connection with the second rotating wheel 140 and the third rotating wheel 161. When the first rotating wheel 131 rotates, power can be transmitted to the second rotating wheel 140 and the third rotating wheel 161 through the rotational connection.

[0060] Further, the drive shaft 300 can be rotated directly by the output end of the motor, or the drive shaft 300 can be configured as the output end of the motor, or the output end of the motor can indirectly drive the drive shaft 300 to rotate through other structures such as a coupling.

[0061] At the same time, in this embodiment, the drive shaft 300 can drive the first rotating wheel 131 directly or indirectly. When the drive shaft 300 directly drives the first rotating wheel 131 to rotate, the drive shaft 300 is configured as a screw, and the first rotating wheel 131 is configured as a transmission gear. By directly driving the two transmission gears with the screw, the direct transmission of power can be achieved. When the drive shaft 300 indirectly drives the first rotating wheel 131 to rotate, the axis of the drive shaft 300 is parallel to the axis of rotation of the first rotating wheel 131. At this time, the power can be indirectly transmitted between the drive shaft 300 and the first rotating wheel 131 through a transmission belt, a sprocket, or a transmission gear. At this time, the drive shaft 300 can drive the first rotating wheels 131 in the two first drive structures 130 to rotate simultaneously. However, this design is not limited thereto. The drive shaft 300 can drive the second drive structure 160 in the two massage components 100 to rotate, that is, to drive the second rotating wheel 140 in the second drive structure 160 to rotate. However, this embodiment is not limited thereto. The drive shaft 300 can also drive the third rotating wheels 161 in the two massage components 100 to rotate.

[0062] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
