[0031] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] Refer to Figures 1 to 5As shown in the figure, the present utility model provides a multifunctional massager, including: a housing 1, a transmission assembly 5, a first ball shaft 3, and a first kneading assembly 4; an installation cavity is provided inside the housing 1, and a limiting cavity is provided on the housing 1; the transmission assembly 5 is arranged in the installation cavity, and the transmission assembly 5 includes an eccentric shaft 503, a first guide member 7, and a first connecting rod 2; the first end of the first connecting rod 2 is slidably connected to the first guide member 7; the second end of the first connecting rod 2 is drivingly connected to the eccentric shaft 503; the first ball shaft 3 is provided with a first limiting sphere 301, passes through the housing 1, and the first limiting sphere 301 is located in the limiting cavity, and the first end of the first ball shaft 3 extends into the installation cavity to be rotatably connected to the first end of the first connecting rod 2; wherein, the rotation of the eccentric shaft 503 drives the first connecting rod 2 to move, so that the first end of the first connecting rod 2 and the first end of the first ball shaft 3 reciprocate along the first guide member 7 and in the rotation plane of the eccentric shaft 503, and the first end of the first connecting rod 2 and the first end of the first ball shaft 3 move synchronously; the first kneading assembly 4 is arranged at the second end of the first ball shaft 3, and the movement of the first ball shaft 3 drives the movement of the first kneading assembly 4.

[0033] Specifically, a first guide member 7 is fixedly installed in the installation cavity, the first end of the first connecting rod 2 is slidably connected to the first guide member 7, the second end of the first connecting rod 2 is drivingly connected to the eccentric shaft 503, the first end of the first ball shaft 3 is rotatably connected to the first end of the first connecting rod 2, the second end of the first ball shaft 3 is connected to the first kneading assembly 4, the first ball shaft 3 is provided with a first limiting sphere 301, the housing 1 is provided with a limiting cavity, and the first limiting sphere 301 is rotatably arranged in the limiting cavity. The eccentric shaft 503 pushes the first connecting rod 2 to perform an eccentric motion, so that the first end of the first connecting rod 2 and the first end of the first ball shaft 3 reciprocate along the first guide member 7 and in the swinging plane of the first connecting rod 2. Refer to Figure 2 and Figure 3 As shown, the first end of the first connecting rod 2 rotates and moves in the first guide member 7, the first end of the first connecting rod 2 and the first end of the first ball shaft 3 move synchronously in the swinging plane of the first connecting rod 2. The swinging plane of the first connecting rod 2 refers to the plane where the first connecting rod 2 is located during the movement process. Thus, the first kneading assembly 4 realizes the scraping massage function while realizing the kneading massage function. During the operation, the scraping massage and the kneading massage are carried out synchronously to improve the comfort performance of the multifunctional massager.

[0034] Refer to Figures 1 to 3 、 Figure 8As shown, the first guide member 7 has a length extension direction L1 and a width extension direction L2. Driven by the eccentric shaft 503, the first end of the first link 2 is slidably connected to the first guide member 7, and the second end of the first link 2 swings along the width extension direction of the first guide member 7. Since the first end of the first link 2 and the first end of the first ball shaft 3 move synchronously in the swinging plane of the first link 2, the position of the first end of the first ball shaft 3 on the first guide member 7 is the same as the position of the first end of the first link 2 on the first guide member 7. In addition, since the first end of the first ball shaft 3 is rotatably connected to the first end of the first link 2, when the first link 2 moves, it drives the first ball shaft 3 to swing around the center of the first limiting sphere 301. The first kneading assembly 4 is provided at the second end of the first ball shaft 3. Therefore, the eccentric shaft 503 drives the first link 2 to move, and further drives the second end of the first ball shaft 3 and the first kneading assembly 4 to swing around the center of the first limiting sphere 301, and the first kneading assembly 4 and the second end of the first ball shaft 3 will swing synchronously along the width extension direction of the first guide member 7 with the first link 2.

[0035] Figure 1 The eccentric shaft 503 is at the position of point A during rotation. At this time, the first end of the first link 2 and the first end of the first ball shaft 3 move to the farthest end in the length extension direction of the first guide member 7. At this time, the projection position of the first kneading assembly 4 on the plane where the first guide member 7 is located is A'. When the eccentric shaft 503 rotates 90 degrees clockwise from the position of point A and reaches position B, that is Figure 2 as shown, at this time, the first link 2 and the first ball shaft 3 swing inward to the maximum angle in the width extension direction of the first guide member 7, and the projection position of the first kneading assembly 4 on the plane where the first guide member 7 is located is B'. When the eccentric shaft 503 rotates 90 degrees clockwise from the position of point B and reaches point C, the first end of the first link 2 and the first end of the first ball shaft 3 move to the nearest end in the length extension direction of the first guide member 7. At this time, the distance between the first end of the first link 2 and the transmission assembly 5 is the closest, and the projection position of the first kneading assembly 4 on the plane where the first guide member 7 is located is C'. When the eccentric shaft 503 rotates 90 degrees clockwise from the position of point C and reaches point D, that is Figure 3 as shown, at this time, the first link 2 swings outward to the maximum angle relative to the width extension direction of the first guide member 7, and the projection position of the first kneading assembly 4 on the plane where the first guide member 7 is located is D'. When the eccentric shaft 503 moves from point A, successively through point B and point C to point D, the schematic diagram of the movement trajectory of the first kneading assembly 4 projected on the plane where the first guide member 7 is located is as Figure 8 shown. When the first kneading assembly 4 passes through A', B', C', D' and then returns to A', that is, the first kneading assembly 4 moves up and down along the neck to realize the kneading and massaging action on the neck.

[0036] Meanwhile, when the first kneading component 4 swings around the center of the first limiting sphere 301, in the plane where the length extension direction of the first ball shaft 3 and the length extension direction of the first connecting rod 2 are located, the movement track of the first kneading component 4 is arc-shaped, that is Figure 9 As shown, specifically, when the eccentric shaft 503 is at positions A, B, C, and D, in the plane where the length extension direction of the first ball shaft 3 and the length extension direction of the first connecting rod 2 are located, the corresponding positions of the first kneading component 4 in this plane are A'', B'', C'', and D''. When the eccentric shaft 503 moves from point A through points B and C to point D in sequence, the first kneading component 4 passes through A'', B'', C'', D'' and then returns to A''. Therefore, the first kneading component 4 performs an arc-shaped scraping and massaging action on the human neck, simulating scraping massage. Therefore, during the movement of the first kneading component 4, scraping massage and kneading massage can be achieved simultaneously.

[0037] In some embodiments of the present utility model, the housing 1 includes a first housing 101, a second housing 102, and a third housing 103. The first housing 101 and the second housing 102 enclose to form an installation cavity. A first hemispherical groove 1021 is opened on the lower end surface of the second housing 102. A second hemispherical groove 1031 is provided on the third housing 103. The second housing 102 and the third housing 103 enclose to form a limiting cavity. The first ball shaft 3 passes through the second housing 102 and the first end extends into the installation cavity, and the limiting ball is rotatably arranged in the limiting cavity.

[0038] Specifically, the first housing 101 and the second housing 102 of the housing 1 enclose to form an installation cavity. The first connecting rod 2 and the transmission component 5 are arranged in the installation cavity. The first end of the first ball shaft 3 passes through the limiting cavity to extend into the installation cavity and is in transmission connection with the first connecting rod 2. By covering the second housing 102, the concealed installation of the first connecting rod 2 and the transmission component 5 is realized, avoiding corrosion and pollution of the external environment and improving reliability. A limiting cavity is opened on the second housing 102. The first limiting sphere 301 of the first ball shaft 3 is installed in the limiting cavity. The limiting cavity realizes the position limitation of the first limiting sphere 301, so as to ensure that when the first connecting rod 2 slides on the first guiding member 7, the first ball shaft 3 is pushed to swing around the center of the first limiting sphere 301.

[0039] It can be understood that a first hemispherical groove 1021 is opened on the lower end surface of the second housing 102. The housing 1 further includes a third housing 103. A second hemispherical groove 1031 is provided on the third housing 103. The first hemispherical groove 1021 and the second hemispherical groove 1031 form a limiting cavity to limit the position of the first ball shaft 3.

[0040] It can be understood that the first hemispherical groove 1021 is provided on the upper end surface of the second housing 102. The third housing 103 is located above the second housing 102. The third housing 103 is provided with a second hemispherical groove 1031. The first hemispherical groove 1021 and the second hemispherical groove 1031 enclose a limiting cavity.

[0041] In some embodiments of the present utility model, the multifunctional massager further includes a driving member 6. The transmission assembly 5 includes at least one driving wheel 501 and a plurality of driven wheels 502. The driving wheel 501 and the driven wheels 502 are meshed and connected. The output end of the driving member 6 is in transmission connection with the driving wheel 501. An eccentric hole is provided on the driven wheel 502. One end of the eccentric shaft 503 is inserted into the eccentric hole, and the other end of the eccentric shaft 503 is adapted to be in transmission connection with the first link 2.

[0042] Specifically, the driving member 6 is fixed on the first housing 101. The output end of the driving member 6 passes through the first housing 101 to extend into the installation cavity and is in transmission connection with the transmission assembly 5. In the present utility model, the driving member 6 is a driving motor.

[0043] It can be understood that the output end of the driving member 6 is in transmission connection with the driving wheel 501. The driving member 6 drives the driving wheel 501 to rotate. By providing a plurality of driven wheels 502, the driving wheel 501 and the driven wheels 502 are meshed and connected. The driving wheel 501 drives the driven wheels 502 to rotate. An eccentric hole is provided on the driven wheel 502. One end of the eccentric shaft 503 is inserted into the eccentric hole. The other end of the eccentric shaft 503 is in transmission connection with the first link 2. The driven wheel 502 rotates to cause the eccentric shaft 503 to rotate and drive the first link 2 to move, so that the first end of the first link 2 and the first end of the first ball shaft 3 reciprocate along the first guide member 7 and in the rotation plane of the eccentric shaft 503. The first end of the first link 2 and the first end of the first ball shaft 3 move synchronously; the first kneading assembly 4 is provided at the second end of the first ball shaft 3. The movement of the first ball shaft 3 drives the movement of the first kneading assembly 4. Thus, the effects of scraping massage and kneading massage are achieved. The distance between the eccentric hole and the center of the driven wheel 502 changes, and the projection trajectory of the first kneading assembly 4 in the plane where the first guide member 7 is located also changes accordingly. When the distance between the eccentric hole and the center of the driven wheel 502 becomes larger, that is, the distance between the rotation axis of the eccentric shaft 503 and the rotation axis of the driven wheel 502 becomes larger, the swing amplitude of the second end of the first link 2 along the width extension direction of the first guide member 7 also becomes larger. In the projection of the movement trajectory of the first kneading assembly 4 in the plane where the first guide member 7 is located, the distance between the two points B' and D' also becomes larger, and the massage amplitude of the first kneading assembly 4 becomes larger, and the massage area increases accordingly. On the contrary, when the distance between the eccentric hole and the center of the driven wheel 502 becomes smaller, the distance between the two points B' and D' also becomes smaller, the massage amplitude of the first kneading assembly 4 becomes smaller, and the massage area decreases accordingly.

[0044] Refer to Figure 4As shown, in some embodiments of the present utility model, the length extension direction of the first guide member 7 passes through the central axis of the driven wheel 502, and the first end of the first link 2 is provided with a first connection portion 201 slidably connected to the first guide member 7.

[0045] Specifically, by setting the length extension direction of the first guide member 7 to pass through the central axis of the driven wheel 502, the effect of labor saving is achieved, the structural compactness is further improved, and the reliability of the structure is ensured.

[0046] In some embodiments of the present utility model, the first guide member 7 is a guide groove formed on the first housing 101 or a guide shaft fixed to the first housing 101.

In the plane where the length extension direction of the first link 2 and the length extension direction of the first ball shaft 3 are located, the first connection block 302 is rotatably connected to the first connection groove 202.

[0048] Refer to Figure 4 、 Figure 6 and Figure 7 As shown, specifically, by providing a first connection groove 202 at one end of the first link 2 and a first connection block 302 at one end of the first ball shaft 3, the first connection block 302 is in the shape of an inclined cylinder or semi-circular ring, and the two side walls of the first connection groove 202 limit the two sides of the first connection block 302 to ensure that in the swinging plane of the first link 2, the first end of the first link 2 and the first end of the first ball shaft 3 move synchronously; the first connection block 302 and the first connection groove 202 are rotatably connected, thereby avoiding excessive torque when the first link 2 pushes the first ball shaft 3 to rotate around the center of the first limiting sphere 301, resulting in breakage of the first ball shaft 3, and the rotational connection between the first ball shaft 3 and the first link 2 provides buffering at the connection node, thereby improving the reliability of the structure.

[0049] In some embodiments of the present utility model, the first kneading assembly 4 includes a connecting member 401 sleeved on the first ball shaft 3, and a kneading wheel 402 rotatably provided on the connecting member 401. There are two kneading wheels 402, and the diameter of the outer kneading wheel 402 is larger than the diameter of the inner kneading wheel 402.

By providing two kneading wheels 402 of different sizes, it is ergonomic, improves the fit between the human body and the kneading wheel 402, and further improves the user experience.

[0051] It can be understood that the first kneading component 4 is detachably connected to the first ball shaft 3 to improve versatility.

[0052] In some embodiments of the present invention, the multifunctional massager further comprises a second kneading component 8, a second connecting rod 11, a second guide member 9 and a second ball shaft 10.

Specifically, when the second kneading assembly 8 is used for neck massage, the first kneading assembly 4 and the second kneading assembly 8 move relative to or away from each other, and the first kneading assembly 4 and the second kneading assembly 8 can achieve massage of the neck.
