Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] like Figures 1 to 3 As shown, the massager provided in the embodiments of this application includes a housing 10, a power mechanism 20, a rocking assembly 30, a swing assembly 40, and a massage hammer 50. The power mechanism 20 is mounted on the housing 10 and includes a power output shaft 21. The rocking assembly 30 includes a connecting portion 31 and a rocking portion 32 connected by a transmission connection. The rocking portion 32 is provided with a first rocker arm 321. The power output shaft 21 is connected to the connecting portion 31, and the connecting portion 31 rotates synchronously with the power output shaft 21, driving the first rocker arm 321 to rock. The swing assembly 40 has a first connecting end 41, a second connecting end 42, and a mounting structure 43 located between the first connecting end 41 and the second connecting end 42. The swing assembly 40 is assembled on the housing 10 through the mounting structure 43. The first connecting end 41 is connected to the first rocker arm 321, and the first rocker arm 321 drives the first connecting end 41 to cause the second connecting end 42 to swing back and forth. The massage hammer 50 is connected to the second connecting end 42 and located outside the housing 10. The axial direction of the massage hammer 50 intersects the direction from the first connecting end 41 to the second connecting end 42. The massage hammer 50 swings synchronously with the second connecting end 42 of the swing assembly 40 and taps to massage the user's first area to be massaged. In the embodiments of this application, the first area to be massaged refers to the user's back.

[0042] "The first rocker arm 321 rocking" means that when the first rocker arm 321 does not combine with other movements, that is, when the first rocker arm 321 only rocks, the end of the first rocker arm 321 near the power output shaft 21 is basically still, and the end of the first rocker arm 321 away from the power output shaft 21 rotates around an axis perpendicular to the power output shaft 21; "The second connecting end 42 reciprocating" means that when the second connecting end 42 does not combine with other movements, that is, when the second connecting end 42 only oscillates, the second connecting end 42 reciprocates with an arc-shaped trajectory centered on the connection position between the mounting structure 43 and the housing 10.

[0043] In the massager provided in the embodiments of this application, the housing 10 provides support for components such as the power mechanism 20, the rocking component 30, the swinging component 40, and the massage hammer 50, so that the various components can be assembled and used normally for massaging the user's back. When a user uses the massager, they wear it and place the massage hammer 50 on their back. Upon activating the massager, the massage hammer 50 is powered on to perform a tapping massage on the user's back. Simultaneously, the power mechanism 20 is powered on, causing the power output shaft 21 to rotate and output power. This drives the adapter 31 of the rocking assembly 30 to rotate synchronously. The adapter 31 then drives the first rocker arm 321 of the rocking part 32 to rock. The first rocker arm 321 then drives the first connecting end 41 of the swing assembly 40, causing the second connecting end 42 of the swing assembly 40 to swing back and forth. This, in turn, causes the massage hammer 50 to swing back and forth. In other words, the massage hammer 50 swings synchronously with the second connecting end 42 of the swing assembly 40 while simultaneously performing a tapping massage on the user's back, thus expanding the area of ​​the massage hammer 50 that is being tapped on the user's back. The area traversed by each massage hammer 50 as it swings with the second connecting end 42 is as follows: Figure 4 The range of motion of the massage hammer 50 within the mid-β angle allows the user's back muscles to relax, relieving back pain and discomfort. In other words, this massager can meet people's needs for back massage to relieve back pain and discomfort.

[0044] In the massager of the embodiments of this application, the housing 10 includes a housing body 11 and a housing cover 12 that overlap each other. Components such as the power mechanism 20, the rocking assembly 30, the oscillating assembly 40, and the massage hammer 50 are all mounted on the housing body 11. The housing cover 12 covers the power mechanism 20 to protect it. This massager includes, but is not limited to, battery-powered devices. For example... Figure 2As shown, the massager also includes a battery 70 and a control circuit board 24. The main body 11 has a battery compartment for accommodating the battery 70, and the battery compartment cover 13 is closed when the battery 70 is placed into the battery compartment to protect the battery 70. The control circuit board 24 is locked to the main body 11 by screws. The battery 70 is electrically connected to the control circuit board 24, and the power mechanism 20 and the massage hammer 50 are also electrically connected to the control circuit board 24.

[0045] like Figure 2 As shown, the massage hammer 50 includes a first hammer shell 511, a second hammer shell 512, a hammer sleeve 52, an electromagnetic module 53, and a hammer head 54. The first hammer shell 511 and the second hammer shell 512 are mated to form a receiving cavity and connected to the second connecting end 42. The hammer sleeve 52 is fixedly installed between the first hammer shell 511 and the second hammer shell 512, with one end of the hammer sleeve 52 extending into the receiving cavity and the other end extending to the outside. The hammer sleeve 52 is fitted onto the hammer head 54. The electromagnetic module 53 is installed in the receiving cavity and is drivenly connected to the hammer head 54. When the electromagnetic module 53 is energized, it drives the hammer head 54 to slide back and forth along the axial direction of the hammer sleeve 52, thereby performing a tapping massage on the user's back.

[0046] In some embodiments of this application, the massager may also be a control circuit board 24 with wires extending from it and connected to an external power source, i.e., wire-powered, to power the power mechanism 20 and the massage hammer 50. In other embodiments of this application, battery power and wire-powered power can coexist, meaning the massager can be either battery-powered or wire-powered. When a user uses the massager to massage their back while walking, battery power is used; when the user is in a fixed position (such as sitting in a chair) using the massager to massage their back, wire power can be used, simultaneously charging the battery 70. Of course, battery power can also be used as long as the battery has sufficient charge.

[0047] like Figure 2 , Figure 6 and Figure 7As shown, the adapter 31 includes a first adapter 311, a second adapter 312, and an end cap 313. The first adapter 311 is connected to the end of the power output shaft 21 and rotates synchronously with the power output shaft 21. The second adapter 312 includes a connecting disc 3121 and a connecting post 3122 connected together, with the connecting disc 3121 connected to the first adapter 311. Specifically, the first adapter 311 includes a body 3111 and an adapter protrusion 3112 connected to the body 3111. The body 3111 has a insertion hole 3113 into which the second power shaft is inserted. The connecting disc 3121 has a slot that matches the adapter protrusion 3112, and the adapter protrusion 3112 is inserted into the slot so that the first adapter 311 and the second adapter 312 can rotate synchronously. Furthermore, the connecting post 3122 is located on the side of the connecting plate 3121 opposite to the first adapter 311. The rocking part 32 is also provided with a mounting hole 323, and the connecting post 3122 is rotatably mounted in the mounting hole 323. The axial direction of the connecting post 3122 intersects the axial direction of the power output shaft 21 at an acute angle. In this way, when the second power shaft rotates and drives the first adapter 311 and the second adapter 312 to rotate synchronously, the connecting post 3122 rotates in the mounting hole 323, and the connecting post 3122 drives the first rocker arm 321 and the second rocker arm 322 to rock, thereby causing the massage head assembly 60 to knead and massage the user's shoulders, relaxing the shoulder muscles and relieving shoulder and back fatigue.

[0048] In the massager provided in the embodiments of this application, such as Figure 2 , Figure 6 and Figure 7 As shown, the connecting post 3122 passes through the assembly hole 323 and is connected to the end cap 313 to prevent the connecting post 3122 from coming out of the assembly hole 323.

[0049] In some embodiments of the massager provided in this application, the first adapter 311 and the second adapter 312 are integrally formed. Preferably, the integral first adapter 311 and the second adapter 312 are injection molded from plastic material using an injection molding process, which has high production efficiency and helps to improve the overall production efficiency of the massager. Furthermore, the overall strength of the integrally formed first adapter 311 and the second adapter 312 is better than the connection strength between the separate first adapter 311 and the second adapter 312, resulting in a more stable transmission effect.

[0050] In the massager provided in this embodiment, the housing 10 is provided with a limiting part 14 that restricts the first rocker arm 321, such as... Figure 2As shown, the first rocker arm 321 is movably connected to the swing assembly 40 after passing through the limiting groove of the limiting part 14, thereby limiting the rocking part 32 from rotating synchronously with the connecting part 31. Since the rocking part 32 is driven to rock by the connecting column 3122, and the axial direction of the connecting column 3122 intersects the axial direction of the power output shaft 21 at an acute angle, the rocking trajectory of the end of the first rocker arm 321 is not a circle. That is, in addition to circumferential rocking, the end of the first rocker arm 321 also moves closer to or further away from the axis of the power output shaft 21. In other words, the rocking trajectory of the end of the first rocker arm 321 is not in the same plane. Therefore, the first rocker arm 321 drives the first connecting end 41 of the swing assembly 40 to rock, rather than swing. If the swing assembly 40 is a rigid whole, then the second connecting end 42, which is linked with the first connecting end 41, will move up and down in addition to swinging. That is to say, the swing trajectory of the second connecting end 42 is not in the same plane, causing the user to feel that the tapping massage of the massage hammer 50 on the user's back is sometimes strong and sometimes weak, which is not conducive to the comfort of the tapping massage of the user's back by the massage hammer 50 on the second connecting end 42. Figure 2 and Figure 3 As shown, the swing assembly 40 includes a first swing arm 410 and a second swing arm 420. One end of the first swing arm 410 is pivotally connected to one end of the second swing arm 420 via a first pin 430. The end of the first swing arm 410 away from the second swing arm 420 is a first connecting end 41, and the end of the second swing arm 420 away from the first swing arm 410 is a second connecting end 42. A mounting structure 43 is disposed on the second swing arm 420 and is assembled to the housing 10 via a second pin 440. Thus, during the swinging of the first rocker arm 321, since one end of the first swing arm 410 is pivotally connected to one end of the second swing arm 420 via the first pin 430, the first swing arm 410 swings up and down around the first pin 430 without causing the second swing arm 420 to swing up and down. That is to say, in the swing assembly 40, only the first swing arm 410 swings with the first rocker arm 321 (here, "swinging" refers to a combination of circumferential swinging and up-and-down swinging motion), and the swing trajectory of the second swing arm 420 is in the same plane. In this way, the user feels that the tapping and pounding massage of the massage hammer 50 on the user's back is more even, which improves the comfort of the massage hammer 50 tapping and pounding massage on the user's back.

[0051] like Figure 2 and Figure 3As shown, the mounting structure 43 is configured as a straight slide groove, and the extension direction of the straight slide groove is consistent with the extension direction of the second swing arm 420. When the mounting structure 43 is assembled to the housing 10 via the second pin 440, that is, the second pin 440 passes through the straight slide groove and is fixedly connected to the housing 10, the second pin 440 can slide relative to the housing 10 within the straight slide groove, and a limiting block 431 is connected to the end of the second pin 440 away from the housing 10 to prevent the second pin 440 from dislodging from the straight slide groove. In this massager, the first swing arm 410 drives the second swing arm 420 to swing, while simultaneously pulling the straight slide groove of the second swing arm 420 relative to the second pin 440, thereby driving the massage hammer 50 to reciprocate.

[0052] In the massager provided in the embodiments of this application, the first connecting end 41 and the first rocker arm 321 are connected by a ball joint. Specifically, as shown... Figure 2 and Figure 3 As shown, the first rocker arm 410 includes a main arm 411 and a connecting member 412. The first connecting end 41 is configured as a ball socket formed by the inner surfaces of the main arm 411 and the connecting member 412. The free end of the first rocker arm 321 is configured as a ball head, which is connected to the ball socket via a ball joint. Alternatively, in other embodiments of the massager, the first rocker arm 321 is provided with a ball socket, and the end of the first rocker arm 410 away from the second rocker arm 420 is configured as a ball head adapted to the ball socket. That is, the first connecting end 41 and the first rocker arm 321 are connected via a ball joint. Through the ball joint connection between the first connecting end 41 and the first rocker arm 321, the first rocker arm 321 can flexibly and stably drive the first rocker arm 410 to rock.

[0053] In the massager provided in the embodiments of this application, such as Figure 2 As shown, the power output shaft 21 includes a first output shaft 211 and a second output shaft 212. The axis of the first output shaft 211 and the axis of the second output shaft 212 are on the same straight line. The extension direction of the end of the first output shaft 211 away from the second output shaft 212 is opposite to the extension direction of the end of the second output shaft 212 away from the first output shaft 211. Furthermore, the power mechanism 20 also includes a motor 22 and a reducer 23. The motor 22 is electrically connected to the control circuit board 24. The reducer 23 includes an input end and an output end. The rotating shaft of the motor 22 is drivenly connected to the input end of the reducer 23. Both the first output shaft 211 and the second output shaft 212 are connected to the output end, thereby enabling the first output shaft 211 and the second output shaft 212 to rotate synchronously. Figure 1 and Figure 2As shown, both the first output shaft 211 and the second output shaft 212 are connected to a rocking component 30, a swinging component 40, and a massage hammer 50. The massager drives the corresponding massage hammer 50 to reciprocate through the first output shaft 211 and the second output shaft 212, and the massage hammer 50 performs a tapping massage on the user's back. In other words, the massager uses two massage hammers 50 simultaneously to tap and massage the left and right sides of the user's back (divided by the user's spine), further expanding the area of ​​tapping and massaging the user's back. In the width direction of the back, the reciprocating distance of the two massage hammers 50 can basically completely cover the user's back, thereby relaxing the muscles throughout the entire back area and relieving the user's back pain and discomfort.

[0054] like Figures 1 to 3 As shown, the rocking part 32 is further provided with a second rocker arm 322. The free end of the second rocker arm 322 extends in the opposite direction to the free end of the first rocker arm 321, and the free end of the second rocker arm 322 extends to the outside of the housing 10. The massager also includes a massage head assembly 60, which is connected to the free end of the second rocker arm 322. The massage head assembly 60 is used to knead and massage the user's second area to be massaged. In the embodiment of this application, the second area to be massaged refers to the user's shoulder. That is to say, the massager of this embodiment not only performs a tapping massage on the user's back, but also simultaneously performs a kneading massage on the user's shoulder, so that the muscles of the user's back are relaxed, and the muscles of the user's shoulder are also relaxed, thereby relieving shoulder and back fatigue.

[0055] Specifically, the massage head assembly 60 includes a mounting shaft 61 and a massage head 62. The mounting shaft 61 is fixedly mounted on the free end of the second rocker arm 322, and the massage head 62 is rotatably connected to the mounting shaft 61. When the second rocker arm 322 drives the massage head assembly 60 to rock, and the massage head 62 contacts the user's shoulder, the massage head 62 rotates relative to the mounting shaft 61. That is, when the massage head 62 performs a kneading massage on the user's shoulder, there is rolling friction between it and the shoulder, which reduces resistance and helps to improve the comfort and effectiveness of the kneading massage.

[0056] Since the connecting post 3122 is rotatably mounted in the mounting hole 323, when the connecting post 3122 causes the rocking part 32 to rock, there will be friction between the port sidewall of the mounting hole 323 and the end cap 313. To reduce the friction between the port sidewall of the mounting hole 323 and the end cap 313, such as... Figure 3 and Figure 5 As shown, the side wall of the mounting hole 323 facing the end cover 313 is provided with a plurality of ball grooves 324 arranged in the circumferential direction. The ball grooves 324 are used to accommodate balls, and the end cover 313 contacts the balls.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
