[0013] In one embodiment, the second driving structure further includes a guiding structure and a second driving groove formed in the second rotating wheel. The second eccentric shaft is slidably disposed in the guiding structure and slidably penetrates through the second driving groove. When the second rotating wheel rotates, the second eccentric shaft can be driven to slide along the guiding structure through the second driving groove.

[0014] In one embodiment, the guiding structure is configured as an elliptical guiding groove, and the second eccentric shaft slides along the elliptical guiding groove.

[0015] In one embodiment, the massager is provided with a base and a cover body. The base is provided with the elliptical guiding groove, and the cover body is provided with an elliptical hole. One end of the second eccentric shaft is slidably disposed in the elliptical guiding groove, the other end passes through the second driving groove and is disposed in the first driving groove.

[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 300, wherein 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 disposed at the second end 122. The movable arm 120 is movably installed on the housing 300. The first massage head 110 can move following the movement of the movable arm 120, and the massage action is completed through the movement of the first massage head 110.

[0043] The first driving structure 130 and the second driving structure 140. The first driving structure 130 includes a first eccentric shaft 131. The first end 121 is rotatably connected to the first eccentric shaft 131. The first driving structure 130 drives the first end 121 through the first eccentric shaft 131 to make the first end 121 rotate around the rotation axis of the first eccentric shaft 131. The second driving structure 140 is drivingly connected to the movable arm 120 to make the second end 122 swing along a preset trajectory. Since the first massage head 110 is disposed on the movable arm 120 near the second end 122, when the second end 122 of the movable arm 120 swings along the preset trajectory, the first massage head 110 can also swing along the preset trajectory, thereby completing the massage action. At this time, the first massage head 110 can swing along the preset trajectory, so that the massage range of the first massage head 110 is larger than that of the massage head performing fixed-point massage, and thus the technical problems existing in the prior art can be solved. At the same time, the first end 121 of the movable arm 120 can rotate around the rotation axis of the first eccentric shaft 131, so that when the movable arm 120 moves, both the first end 121 and the second end 122 can move. In this way, when the second end 122 moves, its range can be increased. 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 preset trajectory also increases. At this time, when the first massage head 110 massages along the preset trajectory, the massage range of the first massage head 110 can also be increased, further realizing a larger range of massage.

[0044] In one embodiment, referring to Figure 2, the first driving structure 130 further includes a first rotating wheel 132, and the first eccentric shaft 131 is disposed on the first rotating wheel 132. When the first rotating wheel 132 rotates, it can drive the movable arm 120 through the first eccentric shaft 131, so that the first end 121 rotates around the rotation axis of the first rotating wheel 132. In this embodiment, there are various ways to drive the first rotating wheel 132, which can be directly driven or indirectly driven. When directly driven, the first rotating wheel 132 is directly connected to the output end of the motor. At this time, the motor can directly drive the first rotating wheel 132 to rotate. When the first rotating wheel 132 rotates, the first eccentric shaft 131 can rotate around the rotation axis of the first rotating wheel 132. At the same time, the first end 121 of the movable arm 120 can also rotate around the rotation axis of the first rotating wheel 132. When indirectly driven, the first rotating wheel 132 can be indirectly connected to the output end of the motor through a transmission belt, a chain, or a transmission gear. The motor indirectly transmits power to the first rotating wheel 132 to make the first rotating wheel 132 complete rotation. At the same time, when the first rotating wheel 132 is indirectly driven, according to different transmission methods, the rotation direction of the first rotating wheel 132 may be the same as or different from the rotation direction of the output end of the motor. For example, when the first rotating wheel 132 and the output end of the motor are indirectly driven through a synchronous belt or a chain, the rotation direction of the first rotating wheel 132 is the same as the rotation direction of the output end of the motor. When the first rotating wheel 132 and the output end of the motor are indirectly driven through a transmission gear, especially when the first rotating wheel 132 is configured as a transmission gear and the output end of the motor is also equipped with a transmission gear, and the two transmission gears are directly meshed, the rotation direction of the first rotating wheel 132 is opposite to the rotation direction of the output end of the motor.

[0045] In one embodiment, referring to Figure 1 , Figure 2 , the second driving structure 140 includes a second rotating wheel 141 and a second eccentric shaft 142. The movable arm 120 is provided with a first driving groove 123, and the first driving groove 123 extends along the length direction of the movable arm 120. The second eccentric shaft 142 is slidably inserted into the first driving groove 123; when the second rotating wheel 141 rotates, it can drive the second end 122 to swing along a preset trajectory through the second eccentric shaft 142. At this time, the second eccentric shaft 142 reciprocates in the first driving groove 123.

[0046] 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 second eccentric shaft 142. The second eccentric shaft 142 is slidably disposed in the guide rail, and the second eccentric shaft 142 is rotatably connected to the second rotating wheel 141. At this time, when the second rotating wheel 141 rotates, the second eccentric shaft 142 drives the guide rail, and the guide rail and the movable arm 120 move together. When the movable arm 120 moves, it can drive the second end 122 to swing along a preset trajectory. At this time, the second eccentric shaft 142 reciprocates in the guide rail. Since the second eccentric shaft 142 is rotatably connected to the second rotating wheel 141, when the second eccentric shaft 142 reciprocates along the guide rail, the second eccentric shaft 142 rotates relative to the second rotating wheel 141.

[0047] In one embodiment, referring to Figure 2 , the second rotating wheel 141 and the first rotating wheel 132 are in transmission connection, and the transmission connection between the second rotating wheel 141 and the first rotating wheel 132 can be direct connection or indirect connection. When the second rotating wheel 141 and the first rotating wheel 132 are directly connected, the second rotating wheel 141 and the first rotating wheel 132 can be configured as transmission gears, and the direct connection is completed by the meshing of the two transmission gears. When the second rotating wheel 141 and the first rotating wheel 132 are indirectly connected, the second rotating wheel 141 and the first rotating wheel 132 can be indirectly connected by means of a transmission belt, a chain, or a transmission gear. Since the second rotating wheel 141 and the first rotating wheel 132 are in transmission connection, at this time, driving one of them can make the other follow and rotate. However, the present design is not limited to this. In other embodiments, the second rotating wheel 141 may not be in transmission connection with the first rotating wheel 132, and the second rotating wheel 141 can be driven to rotate indirectly or directly by a motor. For the way of indirectly or directly driving the second rotating wheel 141 by the motor, the cooperation mode between the first rotating wheel 132 and the motor described above can be referred to.

[0048] In one embodiment, referring to Figure 1 , Figure 2 , Figure 3, the second driving structure 140 further includes a guiding structure 143 and a second driving groove 1411 formed in the second rotating wheel 141. The second eccentric shaft 142 is slidably disposed in the guiding structure 143 and passes through the second driving groove 1411. When the second rotating wheel 141 rotates, the second driving groove 1411 drives the second eccentric shaft 142 to slide along the guiding structure 143 and reciprocate within the second driving groove 1411. Further, since the second eccentric shaft 142 passes through the second driving groove 1411, the connection line between the axis of the second eccentric shaft 142 and the axis of rotation of the second rotating wheel 141 is parallel to the length extension direction of the second driving groove 1411 or is set at a certain angle. When the connection line is parallel to the extension direction or forms a non-ninety-degree angle, the width of the second driving groove 1411 is adapted to the diameter of the second eccentric shaft 142. When the angle is ninety degrees, the width of the second driving groove 1411 is greater than the diameter of the second eccentric shaft 142. At this time, in order to enable the second driving groove 1411 to drive the second eccentric shaft 142 to slide along the guiding structure 143, a transmission member is further provided between the second driving groove 1411 and the second driving groove 142. The transmission member is used to transmit the power of the second driving groove 1411 to the second eccentric shaft 142 so that the second eccentric shaft 142 slides along the guiding structure 143. That is, the second driving groove 1411 pushes the second eccentric shaft 142 to slide along the guiding structure 143 through the transmission member, and the transmission member can be a rod-shaped structure. In this embodiment, the second rotating wheel 141 drives the second eccentric shaft 142 to rotate. The movement track of the second eccentric shaft 142 is affected by the guiding structure 143. According to different shapes of the guiding structure 143, the movement track of the second eccentric shaft 142 is also different.

[0049] In this embodiment, referring to Figure 3, the guiding structure 143 is configured as an elliptical annular guide rail, and the second eccentric shaft 142 slides along the elliptical annular guide rail. At this time, the moving trajectory of the second eccentric shaft 142 is elliptical. At the same time, in this embodiment, when the moving trajectory of the second eccentric shaft 142 is elliptical, when the second eccentric shaft 142 moves to different positions, affected by the elliptical contour, the moving speed corresponding to the second eccentric shaft 142 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 thereto. In other embodiments, the guiding structure 143 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. Among them, when the guiding structure 143 is configured as a quadrilateral guide rail, in order to facilitate the second eccentric shaft 142 to pass through the sharp corners of the quadrilateral guide rail, a bearing can be sleeved outside the second eccentric shaft 142 to reduce the friction between the second eccentric shaft 142 and the sharp corners of the quadrilateral guide rail, so that the second eccentric shaft 142 can pass through. However, this design is not limited thereto. In other embodiments, when the guiding structure 143 is configured as a quadrilateral guide rail, the sharp corners of the quadrilateral guide rail are processed into arcs so that the second eccentric shaft 132 can pass through the sharp corners of the quadrilateral guide rail.

[0050] In one embodiment, referring to Figure 1 , Figure 2 , Figure 3 , the massager is provided with a base 310 and a cover 320. The base 310 is provided with an elliptical guide groove, and the cover 320 is provided with an elliptical hole 321. One end of the second eccentric shaft 142 slides in the elliptical guide groove, and the other end passes through the second driving groove 1411 and slides in the first driving groove 123; when the second eccentric shaft 142 slides along the elliptical guide groove, the first rotating wheel 132 can limit the second eccentric shaft 142 in the elliptical guide groove. In this embodiment, the second eccentric shaft 142 needs to be installed into the elliptical guide groove first, and then the second rotating wheel 141 is installed. When installing the second rotating wheel 141, the second eccentric shaft 142 passes through the second driving groove 1411. At this time, when the second eccentric shaft slides along the elliptical guide groove, the second rotating wheel can limit it in the elliptical guide groove to prevent it from disengaging from the elliptical guide groove.

[0051] In one embodiment, referring to Figure 4 , Figure 5 , Figure 6, the massage component 100 further includes a second massage head 160 and a third driving structure 150, and the third driving structure 150 rotates the second massage head 160. In this embodiment, the third driving structure 150 can drive the second massage head 160 to rotate directly or indirectly. For direct driving, the third driving structure 150 is configured as a motor, and the output end of the motor directly drives the second massage head 160 to rotate. For indirect driving, the third driving structure 150 can indirectly drive the second massage head 160 to rotate through a transmission belt, transmission gears, or a chain by the motor.

[0052] In one embodiment, referring to Figure 4 , Figure 5 , Figure 6 , the third driving structure 150 can also adopt the following structure. The third driving structure 150 includes a third rotating wheel 151 and a transmission structure 152, and the second massage head 160 is installed on the transmission structure 152; when the third rotating wheel 151 rotates, the third rotating wheel 151 drives the transmission structure 152 to rotate the second massage head 160. In this embodiment, the third rotating wheel 151 can be driven directly or indirectly. When directly driven, the output end of the motor directly drives the third rotating wheel 151 to rotate. At this time, the third rotating wheel 151 drives the transmission structure 152 to rotate, so that the transmission structure 152 drives the second massage head 160 to rotate. When indirectly driven, the motor indirectly drives the transmission structure 152 through a transmission belt, transmission gears, or a chain, so that the transmission structure 152 drives the second massage head 160 to rotate. At the same time, in this embodiment, the transmission structure 152 can be a connecting rod or a rotating wheel structure, which is not limited here. When the transmission structure 152 is configured as a connecting rod, one end of the connecting rod is connected to the second massage head 160, and the other end is connected to the third rotating wheel 151. When the transmission structure 152 is configured as a rotating wheel structure, the second massage head 160 is installed on the rotating wheel structure, and the rotating wheel structure is in transmission connection with the third rotating wheel 151.

[0053] In one embodiment, referring to Figure 4 , Figure 5 , Figure 6 , the third rotating wheel 151 is provided with an eccentric hole 1511;

[0054] The transmission structure 152 includes a transmission rod 1521, a spherical portion 1522 provided on the transmission rod 1521, a universal shaft seat 1523, and a universal shaft fixing cover 1524. The universal shaft fixing cover 1524 is used to restrict the spherical portion 1522 to move within the universal shaft seat 1523. One end of the transmission rod 1521 is movably inserted into the eccentric hole 1511, and the second massage head 160 is installed at the other end of the transmission rod 1521. When the third rotating wheel 151 rotates, the eccentric hole 1511 drives the transmission rod 1521. One end of the transmission rod 1521 inserted into the eccentric hole 1511 rotates following the eccentric hole 1511. Under the action of the spherical portion 1522, the end of the transmission rod 1521 connected to the second massage head 160 can rotate. At this time, the transmission rod 1521 can make the second massage head 160 rotate, thereby enabling the second massage head 160 to perform massage.

[0055] In one embodiment, referring to Figure 4 , Figure 5 , Figure 6 , the first rotating wheel 132 and the third rotating wheel 151 are in transmission connection. In this embodiment, the first rotating wheel 132 and the third rotating wheel 151 can be directly in transmission connection or indirectly in transmission connection. When the first rotating wheel 132 and the third rotating wheel 151 are directly in transmission connection, both the first rotating wheel 132 and the third rotating wheel 151 are configured as transmission gears, and the power transmission between the third rotating wheel 151 and the first rotating wheel 132 is completed by the meshing of the two transmission gears. At the same time, when the second rotating wheel 141 is also configured as a transmission gear and the first rotating wheel 132 and the second rotating wheel 141 are directly in transmission connection, when the number of teeth of the second rotating wheel 141 and the third rotating wheel 151 is designed to be the same, the movements of the first massage head 110 and the second massage head 160 will be in the same frequency, that is, 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 160 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 132 and the third rotating wheel 151 are indirectly in transmission connection, the first rotating wheel 132 and the third rotating wheel 151 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 132 and the third rotating wheel 151 can be transmitted through a transmission belt, or a chain, or a transmission gear.

[0056] In one embodiment, referring to Figure 4 , Figure 5 , Figure 6, the first rotating wheel 132 and the second rotating wheel 141 are drivingly connected through the third rotating wheel 151. That is to say, the first rotating wheel 132 and the second rotating wheel 141 complete indirect power transmission through the third rotating wheel 151. In this embodiment, direct drive or indirect drive can be adopted between the first rotating wheel 132 and the third rotating wheel 151. Similarly, the same applies to the drive mode between the third rotating wheel 151 and the second rotating wheel 141.

[0057] In one embodiment, referring to Figure 1 , Figure 2 , Figure 4 , Figure 5 , the massage components 100 are arranged in two groups;

[0058] The massager further includes a drive shaft 200. The two massage components 100 are symmetrically arranged with respect to the drive shaft 200. The drive shaft 200 is used to drive the first drive structure 130 in the two massage components 100 to rotate, that is, to drive the first rotating wheel 132 in the first drive structure 130 to rotate. At this time, the first rotating wheel 132 is drivingly connected to the second rotating wheel 141 and the third rotating wheel 151. When the first rotating wheel 132 rotates, power can be transmitted to the second rotating wheel 141 and the third rotating wheel 151 through the rotational connection.

[0059] Furthermore, the drive shaft 200 can be rotated directly by the output end of the motor, or the drive shaft 200 can be configured as the output end of the motor, or the output end of the motor can indirectly drive the drive shaft 200 to rotate through other structures such as a coupling.

[0060] At the same time, in this embodiment, the drive shaft 200 can drive the first rotating wheel 132 directly or indirectly. When the drive shaft 200 directly drives the first rotating wheel 132 to rotate, the drive shaft 200 is configured as a screw, and the first rotating wheel 132 is configured as a transmission gear. The two transmission gears can be directly driven by the screw to achieve direct power transmission. When the drive shaft 200 indirectly drives the first rotating wheel 132 to rotate, the axis of the drive shaft 200 is parallel to the axis of rotation of the first rotating wheel 132. At this time, the drive shaft 200 and the first rotating wheel 132 can complete indirect power transmission through a transmission belt, or a sprocket, or a transmission gear. At this time, the drive shaft 200 can drive the first rotating wheels 132 in the two first drive structures 130 to rotate simultaneously. However, this design is not limited to this. The drive shaft 200 can drive the second drive structure 140 in the two massage components 100 to rotate, that is, to drive the second rotating wheel 141 in the second drive structure 140 to rotate. However, this embodiment is not limited to this. The drive shaft 200 can also drive the third drive structure 150 in the two massage components 100 to rotate, that is, to drive the third rotating wheel 151 in the third drive structure 150 to rotate.

[0061] The above are only exemplary embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
