Description

Technical Field

[0001] This utility model relates to the technical field of massage equipment, and more specifically, to a massager. Background Technology

[0002] In daily work and life, people often experience neck, shoulder and back discomfort for various reasons, such as maintaining one posture for a long time at work, or becoming a "head-down generation" by looking at mobile phones for a long time. There is a great demand for multifunctional massagers.

[0003] Currently available massagers include two pairs of different massage heads with kneading functions. However, since the two pairs of massage heads cannot be independently controlled under the drive of a single motor, the massager has a limited range of massage modes. Utility Model Content

[0031] like Figure 1 and Figure 2 As shown in the figure, this utility model provides a massager for massaging the human body. Specifically, the massager of this embodiment is used to knead the neck, shoulders, and back of the human body. The massager provided in this embodiment has multiple massage structures, which are coaxial and independently controlled, so that the massager only needs one drive structure, saving internal space and improving the controllability of multiple massage structures. The following is a detailed description of the specific implementation:

[0032] The massager in this embodiment includes:

[0033] The system comprises: a fixed housing 1; a drive structure 2 mounted on the fixed housing 1; a first output gear 3 connected to the drive structure 2; an output shaft 4 coaxially connected to the first output gear 3; a second output gear 5 movably mounted on the output shaft 4; a first eccentric wheel 6 fixedly connected to the output shaft 4; a second eccentric wheel 7 fixedly connected to the second output gear 5; a first massage structure 8 connected to the first eccentric wheel 6; and a second massage structure 9 connected to the second eccentric wheel 7. A one-way transmission component is provided between the first output gear 3 and the output shaft 4.

[0034] The drive structure 2 is used to drive the first output gear 3 and the second output gear 5 to rotate simultaneously. The drive structure 2 has a first motion state and a second motion state. In the first motion state, the first output gear 3 can drive the output shaft 4 and the first eccentric wheel 6 to rotate, so as to drive the first massage structure 8 to swing. The second output gear 5 drives the second massage structure 9 to move closer to or away from the first massage structure 8 through the second eccentric wheel 7. In the second motion state, the first massage structure 8 is located at a set position, and the second output gear 5 drives the second massage structure 9 to move closer to or away from the first massage structure 8 through the second eccentric wheel 7.

[0035] Here, it can be understood that the fixed shell 1 refers to the shell component used to fix and protect the internal parts of the massager; the fixed shell 1 is a hollow structure, which is used to house and fix the drive structure 2, the first output gear 3, the output shaft 4, the second output gear 5, the first eccentric wheel 6, the second eccentric wheel 7, the first massage structure 8, and the second massage structure 9;

[0036] The drive structure 2 refers to the component used to drive the first massage structure 8 and the second massage structure 9 to perform corresponding massage actions; the drive structure 2 includes, but is not limited to, a motor; the drive structure 2 is provided with a drive shaft, which can be connected to the first output gear 3 and the second output gear 5 to transmit power; specifically, the drive structure 2 has a first motion state and a second motion state, the drive structure 2 outputs power in one direction in the first motion state, and the drive structure 2 outputs power in the opposite direction in the second motion state.

[0037] The first output gear 3 refers to the gear structure used to transmit the power of the drive structure 2; the first output gear 3 is connected to the drive structure 2 in a transmission manner, and the drive structure 2 can drive the first output gear 3 to rotate.

[0038] Output shaft 4 refers to the shaft used for outputting power; output shaft 4 is coaxially arranged with the first output gear 3; a one-way transmission component is provided between output shaft 4 and the first output gear 3, the one-way transmission component refers to a component used for one-way power transmission; the one-way transmission component includes, but is not limited to, a one-way bearing; this embodiment takes a one-way bearing as an example to introduce the power transmission process, that is, when the first output gear 3 rotates in one direction, it can drive the output shaft 4 to rotate in that direction, but when the first output gear 3 rotates in the opposite direction, the first output gear 3 cannot drive the output shaft 4 to rotate in the other direction;

[0039] The second output gear 5 refers to the gear structure used to transmit the power of the drive structure 2; the second output gear 5 is connected to the drive structure 2 in a transmission manner, and the drive structure 2 can drive the second output gear 5 to rotate.

[0040] The first eccentric wheel 6 refers to the eccentric wheel used to drive the first massage structure 8 to perform massage actions; specifically, the first eccentric wheel 6 is connected to the output shaft 4 and the first massage structure 8.

[0041] The second eccentric wheel 7 refers to the eccentric wheel used to drive the second massage structure 9 to perform massage actions; specifically, the second eccentric wheel 7 is connected to the second massage structure 9.

[0042] The working principle of the massager provided in this embodiment is as follows:

[0043] The drive structure 2 has a first motion state and a second motion state. In the first motion state, the drive structure 2 rotates in one direction, driving the first output gear 3 and the second output gear 5 to rotate in that direction. The first output gear 3 drives the output shaft 4 to rotate through a one-way transmission component. Since the output shaft 4 is connected to the first eccentric wheel 6, the output shaft 4 drives the first eccentric wheel 6 to rotate around the axis of the output shaft 4. The first eccentric wheel 6 then drives the first massage structure 8 to perform a massage action. The second output gear 5 drives the second eccentric wheel 7 to rotate around the output shaft 4. The second eccentric wheel 7 drives the second massage structure 9 to perform a massage action.

[0044] Conversely, in the second motion state, the drive structure 2 rotates in the other direction, driving the first output gear 3 and the second output gear 5 to rotate. Since the first output gear 3 and the output shaft 4 are unidirectional transmission components, the first output gear 3 will not drive the output shaft 4 to rotate in the other direction, thereby causing the first eccentric wheel 6 and the first massage structure 8 on the output shaft 4 to remain in the set position, that is, the first massage structure 8 remains in the fixed position; the second output gear 5 drives the second eccentric wheel 7 to rotate around the output shaft 4, and the second eccentric wheel 7 drives the second massage structure 9 to perform massage actions that move closer to or away from the first massage structure 8.

[0045] By adopting the above technical solution, the massager includes a first massage structure 8 and a second massage structure 9 that can be used to massage different parts of the human body respectively. The first massage structure 8 and the second massage structure 9 are connected to the same drive structure 2. They are coaxial and independently controlled, so that the massager only needs one drive structure 2, saving the internal space of the massager. At the same time, the independent control of the first massage structure 8 and the second massage structure 9 is achieved by the rotation of the drive structure 2 in two opposite directions and the cooperation of the first output gear 3, the second output wheel 5 and the output shaft 4, so that the massager has multiple massage modes.

[0046] Please refer to the following: Figure 3 In one embodiment, the fixed housing 1 includes a bottom housing 11 and a first fixed housing 12 connected to the bottom housing 11. The drive structure 2, the first output gear 3 and the second output gear 5 are disposed between the bottom housing 11 and the first fixed housing 12. The first eccentric wheel 6 and the first massage structure 8 are connected to the first fixed housing 12.

[0047] Here, it can be understood that the fixed housing 1 includes a bottom housing 11 and a first fixed housing 12. The first fixed housing 12 is disposed on the bottom housing 11, and the two are used to house the drive structure 2, the first output gear 3 and the second output gear 5. The first eccentric wheel 6 and the first massage structure 8 are connected to the first fixed housing 12, that is, the first eccentric wheel 6 and the first massage structure 8 are directly or indirectly connected to the first fixed housing 12. In this embodiment, the first eccentric wheel 6 and the first massage structure 8 are located on the side of the first fixed housing 12 away from the drive structure 2, the first output gear 3 and the second output gear 5, so that the internal components of the fixed housing 1 are stacked.

[0048] By adopting the above technical solution, the internal components of the fixed shell 1 are stacked, which helps to make the massager smaller.

[0049] In one embodiment, the first fixed housing 12 is provided with a first groove 121, and the first massage structure 8 is provided with a first sliding member 81 that slides in the first groove 121.

[0050] Here, it can be understood that the first slide groove 121 refers to the groove structure used to guide the first massage structure 8 to move along a predetermined trajectory; the first fixed housing 12 is provided with the first slide groove 121, and the first massage structure 8 is provided with the first sliding member 81. The shape and size of the first sliding member 81 match the shape and size of the first slide groove 121, so that the first sliding member 81 can just move along the length direction of the first slide groove 121 in the first slide groove 121. Under the joint limitation of the first sliding member 81, the output shaft 4 and the first eccentric wheel 6, the first massage structure 8 moves along a preset trajectory, that is, performs a massage action.

[0051] By adopting the above technical solution, the first massage structure 8 can perform preset massage actions.

[0052] In one embodiment, a second fixed housing 13 is formed on the portion of the bottom housing 11 near the first fixed housing 12. A connecting rod 14 connecting the second eccentric wheel 7 is provided between the first fixed housing 12 and the second fixed housing 13. A connecting hole 122 is provided on the portion of the first fixed housing 12 corresponding to the second massage structure 9. A connecting rod 123 connected to the second massage structure 9 is movably provided in the connecting hole 122. The connecting rod 123 is movably connected to the connecting rod 14. The second eccentric wheel 7 sequentially drives the connecting rod 14, the connecting rod 123, and the second massage structure 9 to move.

[0053] Here, it can be understood that the fixed shell 1 also includes a second fixed shell 13. The second fixed shell 13 can be manufactured separately from the bottom shell 11 and then assembled, or the second fixed shell 13 can be integrally formed on the bottom shell 11. The second fixed shell 13 is located between the bottom shell 11 and the first fixed shell 12. A connecting rod 14 is provided between the first fixed shell 12 and the second fixed shell 13. The connecting rod 14 is used to connect the second eccentric wheel 7. The first fixed shell 12 is provided with a connecting hole 122. A connecting rod 123 is provided in the connecting hole 122. The connecting rod 123 is connected to the second massage structure 9. At the same time, the connecting rod 123 is movably inserted in the connecting hole 122, that is, the connecting rod 123 can maintain its connection with the connecting hole 122 and can also swing, thereby driving the second massage structure 9 to perform a massage action. It needs to be further explained that the connecting rod 123 is movably connected to the connecting rod 14, that is, the second eccentric wheel 7 can sequentially drive the connecting rod 14, the connecting rod 123 and the second massage structure 9 to move.

[0054] By adopting the above technical solution, the second eccentric wheel 7 and the second massage structure 9 are connected by the connecting rod 14 and the connecting rod 123, and its transmission structure is simple, which makes the massager easy to manufacture.

[0055] In one embodiment, the fixed housing 1 further includes a first eccentric wheel cover 15 covering the first eccentric wheel 6 and a second eccentric wheel cover 16 covering the second eccentric wheel 7; the first eccentric wheel cover 15 is used for axial positioning of the first eccentric wheel 6 and the first massage structure 8, and the second eccentric wheel cover 16 is used for axial positioning of the second eccentric wheel 7 and the connecting rod 14.

[0056] Here, it can be understood that the first eccentric wheel cover 15 refers to the cover used to limit the first eccentric wheel 6 and the first massage structure 8 on the first fixed housing 12, and the first eccentric wheel cover 15 restricts the axial movement of the first eccentric wheel 6 and the first massage structure 8 on the first fixed housing 12; the second eccentric wheel cover 16 refers to the cover used to limit the second eccentric wheel 7 and the connecting rod 14 on the second fixed housing 13, and the second eccentric wheel cover 16 restricts the axial movement of the second eccentric wheel 7 and the connecting rod 14 on the second fixed housing 13.

[0057] By adopting the above technical solution, the possibility of the first eccentric wheel 6 and the second eccentric wheel 7 falling off during eccentric rotation is reduced.

[0058] In one embodiment, the second fixed housing 13 is provided with a second sliding groove 131, the connecting rod 14 is provided with a sliding end that slides in the second sliding groove 131, the sliding end is provided with a limiting groove 141, and the connecting rod 123 is provided with a limiting post 1231 that is limited in the limiting groove 141.

[0059] Here, it can be understood that the sliding end of the connecting rod 14 moves back and forth in the second slide groove 131 under the limitation of the second eccentric wheel 7 and the second slide groove 131. At the same time, the sliding end is also provided with a limiting groove 141, and the connecting rod 123 is provided with a limiting post 1231. Through the cooperation of the limiting post 1231 and the limiting groove 141, the connecting rod 123 moves back and forth. The second massage structure 9 is provided on the end of the connecting rod 123 away from the limiting post 1231.

[0060] Specifically, the sliding end of the connecting rod 14 can reciprocate in the second sliding groove 131. The sliding end is provided with a limiting groove 141. The limiting post 1231 on the connecting rod 123 is limited in the limiting groove 141. That is, the connecting rod 14 can drive the limiting post 1231 to reciprocate through the limiting groove 141 of the sliding end, thereby driving the entire connecting rod 123 to reciprocate, and finally driving the second massage structure 9 to reciprocate.

[0061] By adopting the above technical solution, the connecting rod 123 drives the second massage structure 9 to perform massage actions.

[0062] In one embodiment, the wall of the connecting hole 122 is an inner spherical surface, and the connecting rod 123 is provided with a ball 1232 movably disposed in the inner spherical surface, with the ball 1232 and the inner spherical surface in clearance fit.

[0063] Here, it can be understood that the shape and size of the sphere 1232 match the shape and size of the inner sphere, so that the sphere 1232 is just accommodated in the inner sphere and fits the inner sphere with a gap.

[0064] Specifically, when the sliding end of the connecting rod 14 drives the entire connecting rod 123 to reciprocate, the ball 1232 on the connecting rod 14 is limited by the inner spherical surface. Therefore, the entire connecting rod 123 rotates around the ball 1232, thereby causing the second massage structure 9 on the connecting rod 123 to swing.

[0065] By adopting the above technical solution, the second massage structure 9 was made to swing.

[0066] In one embodiment, the massager includes a drive structure 2, two first output gears 3 respectively disposed on both sides of the drive structure 2, and a second output gear 5 coaxially disposed in correspondence with the first output gears 3; the drive structure 2 is provided with two drive shafts 21, each drive shaft 21 being used to drive the corresponding first output gear 3 and second output gear 5 to rotate.

[0067] Here, it can be understood that the massager includes two sets of massage structures, each set including a first massage structure 8 and a second massage structure 9; each first massage structure 8 corresponds to a first output gear 3, and each second massage structure 9 corresponds to a second output gear 5; the two sets of massage structures share a common drive structure 2. Specifically, the massager includes a drive structure 2, two first output gears 3 and two second output gears 5, with the first output gears 3 and second output gears 5 coaxially arranged; the drive structure 2 is provided with two drive shafts 21, each drive shaft 21 being used to drive the corresponding first output gear 3 and second output gear 5 to rotate.

[0068] By adopting the above technical solution, the two massage structures share a single drive structure 2, saving internal space in the massager and reducing manufacturing costs.

[0069] In one embodiment, each drive shaft 21 is provided with a double gear 22, which includes a first gear 221 and a second gear 222 coaxially fixedly connected to the first gear 221. The first gear 221 is connected to the drive shaft 21 for transmission, and the second gear 222 is used to mesh with the corresponding first output gear 3 and second output gear 5 at the same time.

[0070] By adopting the above technical solution, the transmission between the drive shaft 21 and the first output gear 3 and the second output gear 5 is reliable.

[0071] In one embodiment, the unidirectional transmission component includes an outer bearing ring and an inner bearing ring disposed inside the outer bearing ring. The outer bearing ring is fixedly connected to the first output gear 3 and the outer bearing ring is fixedly connected to the output shaft 4.

[0072] Here, it can be understood that the unidirectional transmission component includes the outer ring of the bearing and the inner ring of the bearing, and the inner ring of the bearing can rotate unidirectionally along the circumference of the inner ring of the bearing.

[0073] By adopting the above technical solution, the first output gear 3 drives the output shaft 4 to rotate in one direction.

[0074] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
