[0030] An embodiment of the present invention provides a massage hand, such as Figures 1 to 3 As shown, it is applied to a shampooing machine, comprising a driving mechanism 72, a connecting assembly 73, a swing arm 74, a first mounting seat 61 and a massage portion 62; the driving mechanism 72 and the connecting assembly 73 are drivingly connected, one end of the swing arm 74 is rotatably connected to the connecting assembly 73, the other end of the swing arm 74 is connected to the massage portion 62, and the massage portion 62 is rotatably connected to the first mounting seat 61; the driving mechanism 72 is used to drive the connecting assembly 73 to move back and forth in a straight line, and the connecting assembly 73 is used to drive the massage portion 62 to rotate through the swing arm 74.

[0031] The driving mechanism 72 can be an electric push rod, a linear stepper motor, or a telescopic cylinder. The output end of the driving mechanism 72 can be bolted, clamped, or welded to the connecting assembly 73, and the driving mechanism 72 drives the connecting assembly 73 to reciprocate linearly. The connecting assembly 73 is provided with a first socket, and the swing arm 74 is provided with a second socket. The first rotating shaft is inserted into the first and second sockets, and the swing arm 74 can rotate relative to the connecting assembly 73. The massage part 62 is provided with a third socket, and the other end of the swing arm 74 is inserted into the third socket. The massage part 62 includes a connecting column 66. The first mounting seat 61 is provided with a second mounting hole. The connecting column 66 is inserted into the second mounting hole to achieve a rotational connection between the massage part 62 and the first mounting seat 61.

[0032] During operation of the driving mechanism 72, the driving mechanism 72 first drives the connecting assembly 73 to move in the negative direction of the Y-axis. The connecting assembly 73 drives one end of the swing arm 74 to move in the negative direction of the Y-axis. Under the limiting action of the first mounting seat 61, one end of the swing arm 74 rotates around the axis of the first rotating shaft. The other end of the swing arm 74 drives the massage part 62 to rotate counterclockwise around the connecting post 66. Then, the driving mechanism 72 drives the connecting assembly 73 to move in the positive direction of the Y-axis. The connecting assembly 73 drives one end of the swing arm 74 to move in the positive direction of the Y-axis. Under the limiting action of the first mounting seat 61, one end of the swing arm 74 rotates around the axis of the first rotating shaft. The other end of the swing arm 74 drives the massage part 62 to rotate clockwise around the connecting post 66. This cycle is repeated to achieve reciprocating rotation of the massage part 62.

[0033] The advantage of such an arrangement is that, through the driving connection between the driving mechanism 72 and the connecting assembly 73, the driving mechanism 72 can drive the connecting assembly 73 to move back and forth in a straight line, and through the rotational connection between one end of the swing arm 74 and the connecting assembly 73, the connecting assembly 73 can drive the swing arm 74 to move back and forth in a straight line, and through the connection between the other end of the swing arm 74 and the massage part 62, the massage part 62 and the first mounting seat 61 are rotationally connected, so that the swing arm 74 can drive the massage part 62 to rotate back and forth, so that the massage part 62 can reciprocate and rub the user's hair, thereby enhancing the cleaning effect on the user's hair.

[0034] like Figure 2 、 Figure 3As shown, the driving mechanism 72 includes a motor 721, an eccentric connecting member 722 and a connecting rod 723. The motor 721 and the eccentric connecting member 722 are driven and connected. One end of the connecting rod 723 is connected to the eccentric connecting member 722, and the other end of the connecting rod 723 is connected to the connecting assembly 73. The motor 721 is used to drive the eccentric connecting member 722 to rotate, the eccentric connecting member 722 is used to drive one end of the connecting rod 723 to perform eccentric motion, and the other end of the connecting rod 723 is used to drive the connecting assembly 73 to perform linear reciprocating motion.

[0035] The motor 721 can be a DC motor, an asynchronous motor, or a synchronous motor. The rotating shaft of the motor 721 can be keyed, pinned, or screwed to the eccentric connector 722. The eccentric connector 722 can be an eccentric sleeve, an eccentric bearing, or a connecting rod. The eccentric connector 722 is provided with a first connecting hole and a second connecting hole. The first connecting hole is provided with a keyway. The rotating shaft of the motor 721 is keyed to the first connecting hole. One end of the connecting rod 723 is provided with a third connecting hole. The first connecting shaft is inserted into the second and third connecting holes. The axis of the first connecting shaft is parallel to and co-linear with the axis of the rotating shaft of the motor 721.

[0036] In one embodiment, the connecting assembly 73 is provided with a fourth connecting hole, the other end of the connecting rod 723 is provided with a fifth connecting hole, and the second connecting shaft is inserted into the fourth and fifth connecting holes. In another embodiment, the massage hand further includes a connecting frame 75, which is welded or screwed to the connecting assembly 73, and the fourth connecting hole is provided on the connecting frame 75.

[0037] During the operation of the motor 721, the rotating shaft of the motor 721 drives the eccentric connector 722 to rotate, and the eccentric connector 722 drives one end of the connecting rod 723 to perform eccentric motion relative to the rotating shaft of the motor 721, and the other end of the connecting rod 723 drives the connecting assembly 73 to reciprocate linearly along the Y-axis direction. For example, during the process of the eccentric connector 722 rotating one circle, the eccentric connector 722 first rotates 90°, and the relative distance between the end of the connecting rod 723 close to the connecting assembly 73 and the rotating shaft of the motor 721 gradually becomes longer, and the connecting rod 723 pushes the connecting assembly 73 forward; the eccentric connector 722 continues to rotate 90°, and the relative distance between the end of the connecting rod 723 close to the connecting assembly 73 and the rotating shaft of the motor 721 gradually becomes shorter, and the eccentric connector 722 drives the connecting assembly 73 to rotate. The connecting rod 723 returns to its original position; the eccentric connecting member 722 continues to rotate 90°, and the relative distance between the end of the connecting rod 723 close to the connecting component 73 and the rotating shaft of the motor 721 becomes longer, and the connecting rod 723 pulls the connecting component 73 backward; then the connecting member 722 continues to rotate 90°, and the relative distance between the end of the connecting rod 723 close to the connecting component 73 and the rotating shaft of the motor 721 gradually becomes shorter, and the eccentric connecting member 722 drives the connecting rod 723 back to its original position.

[0038] The advantage of such an arrangement is that during the operation of the motor 721, the motor 721 only needs to rotate in one direction. The motor 721 and the eccentric connector 722 are driven and connected, so that the motor 721 can drive the eccentric connector 722 to rotate. One end of the connecting rod 723 is connected to the eccentric connector 722, so that the eccentric connector 722 can drive one end of the connecting rod 723 to perform eccentric movement. The other end of the connecting rod 723 is connected to the connecting assembly 73, so that the other end of the connecting rod 723 can drive the connecting assembly 73 to reciprocate linearly, thereby realizing the reciprocating linear motion of the connecting assembly 73, avoiding the torque generated by the switching of the rotation direction of the motor 721 shaft, and making the operation of the motor 721 more stable.

[0039] like Figures 2 to 5 As shown, the massage hand also includes a guide column 711 and a second mounting seat 71, the guide column 711 is connected to the second mounting seat 71, a through hole is opened on the connecting component 73, the guide column 711 is passed through the through hole, and the connecting component 73 is suitable for reciprocating linear motion along the guide column 711.

[0040] The guide post 711 is keyed, clamped, welded, or threadedly connected to the second mounting base 71. The through hole is arranged along the axial direction of the guide post 711, and the connecting assembly 73 can slide relative to the guide post 711. The guide post 711 is arranged along the Y-axis. During the operation of the drive mechanism 72, the drive mechanism 72 drives the connecting assembly 73 to move along the axial direction of the guide post 711.

[0041] The advantage of this arrangement is that the guide column 711 is connected to the second mounting seat 71 by connecting the guide column 711 to achieve the installation of the guide column 711; the guide column 711 is passed through a through hole on the connecting component 73 to guide the connecting component 73; under the guiding action of the guide column 711, the connecting component 73 can move along the axial direction of the guide column 711, thereby achieving the linear reciprocating motion of the connecting component 73; in addition, the guide column 711 limits the displacement of the connecting component 73, making the connecting component 73 more stable during movement.

[0042] like Figures 1 to 4 As shown, a strip hole 714 is provided on the second mounting seat 71, and the length direction of the strip hole 714 is the same as the axial direction of the guide column 711. The connecting component 73 includes a guide slider 731, and the guide slider 731 is passed through the strip hole 714. The guide slider 731 can slide along the strip hole 714; the first mounting seat 61 and the driving mechanism 72 are respectively installed on the opposite sides of the second mounting seat 71.

[0043] In one embodiment, the strip hole 714 is located on the upper side of the guide column 711, the outer wall of the guide slider 731 is in contact with the inner wall of the strip hole 714, and the strip hole 714 is arranged along the Y-axis direction. The guide slider 731 can slide in the strip hole 714. The guide slider 731 can be driven and connected to the driving mechanism 72. The driving mechanism 72 is mounted on the second mounting seat 71, and the driving mechanism 72 is bolted, clamped or welded to the second mounting seat 71. In another embodiment, a mounting bracket is provided on the second mounting seat 71, and the driving mechanism 72 is mounted on the mounting bracket. The first mounting seat 61 can be screwed, clamped or welded to the second mounting seat 71.

[0044] Thus, the first mounting seat 61 and the driving mechanism 72 are respectively installed on the opposite sides of the second mounting seat 71, thereby realizing the installation of the first mounting seat 61 and the driving mechanism 72. The guide sliding block 731 is passed through the strip hole 714, so that the guide sliding block 731 can slide along the strip hole 714, so that the driving mechanism 72 can drive the connecting assembly 73 to move through the guide sliding block 731. The length direction of the strip hole 714 is the same as the axial centerline direction of the guide column 711, so that the guide direction of the guide sliding block 731 is the same as that of the guide column 711, thereby avoiding the strip hole 714 interfering with the movement of the guide sliding block 731.

[0045] like Figures 3 to 5 As shown, the connecting component 73 includes a first connecting member 732 and a second connecting member 733. The first connecting member 732 is driven and connected to the driving mechanism 72. The second connecting member 733 is pin-connected to the swing arm 74. The first connecting member 732 and the second connecting member 733 are respectively pin-connected to the guide column 711. The second connecting member 733 can rotate relative to the guide column 711.

[0046] The first connecting member 732 can be key-connected, screw-connected, or pin-connected to the driving end of the driving mechanism 72. In one embodiment, the first connecting member 732 includes a first limiting plate and a second limiting plate, and the second connecting member 733 is located between the first limiting plate and the second limiting plate. The two end faces of the second connecting member 733 in the axial direction of the guide column 711 are respectively fitted with the first limiting plate and the second limiting plate. A first guide hole is provided on the first limiting plate and the second limiting plate, and a second guide hole is provided on the second connecting member 733. The guide column 711 is passed through the first guide hole and the second guide hole to realize the pin connection between the first connecting member 732 and the second connecting member 733 and the guide column 711. The first connecting member 732 and the second connecting member 733 can both slide along the axial direction of the guide column 711, and the second connecting member 733 can rotate around the axial line of the guide column 711. Thus, by positioning the second connecting member 733 within the first limiting plate and the second limiting plate, the first limiting plate and the second limiting plate can limit the displacement of the second connecting member 733 in the radial direction of the guide column 711, thereby making the second connecting member 733 more stable during movement. The second connecting member 733 includes a first connecting plate and a second connecting plate, and the swing arm 74 is positioned between the first connecting plate and the second connecting plate. The first connecting plate and the second connecting plate are provided with a first connecting hole, and the swing arm 74 is provided with a second connecting hole. A rotating shaft is provided through the first connecting hole and the second connecting hole, and the swing arm 74 can rotate around the axis of the rotating shaft. Thus, by positioning the swing arm 74 between the first connecting plate and the second connecting plate, on the one hand, the first connecting plate and the second connecting plate can limit the position of the swing arm 74, and on the other hand, the connection between the swing arm 74 and the second connecting member is strengthened.

[0047] The advantage of such an arrangement is that the first connecting member 732 is driven and connected to the driving mechanism 72 so that the driving mechanism 72 can drive the first connecting member 732 to reciprocate linearly. The first connecting member 732 and the second connecting member 733 are respectively pin-connected to the guide column 711. On the one hand, the first connecting member 732 can drive the second connecting member 733 to move along the guide column 711. On the other hand, the second connecting member 733 can rotate relative to the guide column 711 to avoid the first connecting member 732 interfering with the rotation of the second connecting member 733. The second connecting member 733 is pin-connected to the swing arm 74 so that the swing arm 74 can rotate relative to the second connecting member 733, thereby realizing the rotational connection between the second connecting member 733 and the swing arm 74.

[0048] like Figure 6 、 Figure 8 As shown, the massage part 62 also includes a connecting column 66. A third through hole is opened on the first mounting seat 61. The connecting column 66 is passed through the third through hole. The swing arm 74 is connected to the connecting column 66. The swing arm 74 is suitable for driving the connecting column 66 to rotate.

[0049] In one embodiment, the first mounting seat 61 includes a first mounting seat body and a cover plate, the third through hole is provided on the first mounting seat body, a limiting hole is provided on the cover plate, the connecting column 66 is passed through the limiting hole and the third through hole, the limiting hole and the third through hole are coaxial, and the cover plate is bolted or screwed to the first mounting seat body. Thus, by providing a limiting hole on the cover plate, the connecting column 66 is simultaneously passed through the limiting hole and the third through hole, so that the limiting hole can limit the connecting column 66 to prevent the connecting column 66 from shaking. The connecting column 66 is also provided with an annular protrusion structure, which is attached to the first mounting seat 61 to clamp the connecting column 66 on the first mounting seat 61 to prevent the connecting column 66 from slipping off the first mounting seat 61. The swing arm 74 is a retractable connecting arm or elastic arm. One end of the swing arm 74 is provided with a threaded structure. A threaded hole is formed in the side wall of the connecting post 66. The swing arm 74 is threadedly connected to the connecting post 66. During the movement of the connecting assembly 73, the connecting assembly 73 drives one end of the swing arm 74 to reciprocate linearly along the Y-axis. One end of the swing arm 74 rotates relative to the connecting assembly 73, and the other end of the swing arm 74 drives the connecting post 66 to rotate.

[0050] The advantage of such an arrangement is that, by passing the connecting column 66 through the third through hole, the connecting column 66 can rotate relative to the first mounting seat 61, thereby realizing a rotational connection between the connecting column 66 and the first mounting seat 61, and by connecting the swing arm 74 to the connecting column 66, the swing arm 74 can drive the connecting column 66 to rotate, thereby realizing the rotation of the massage part 62.

[0051] like Figure 8 As shown, a guide hole 661 is opened on the side wall of the connecting column 66, and the guide hole 661 is arranged along the radial direction of the connecting column 66. The swing arm 74 includes an insertion shaft 741, and the insertion shaft 741 is passed through the guide hole 661, and the insertion shaft 741 can slide along the guide hole 661.

[0052] The guide hole 661 passes through the connecting column 66, and the swing arm 74 includes a connecting head, which is pin-connected to the connecting component 73. The plug-in shaft 741 is threaded or welded to the connecting head. During the movement of the connecting component 73, the connecting component 73 drives one end of the swing arm 74 to move back and forth in a straight line, and one end of the swing arm 74 rotates around the axis of the connecting column 66. The plug-in shaft 741 slides out or extends in the guide hole 661, and drives the connecting column 66 to rotate.

[0053] In another embodiment, the length of the swing arm 74 is telescopically adjustable. The swing arm 74 includes a first connecting tube and a second connecting tube. The first connecting tube has a through hole extending through the first connecting tube body along its axis. The second connecting tube is inserted into the through hole and is slidable relative to the first connecting tube. As the swing arm 74 drives the connecting post 66 to rotate, the second connecting tube can slide toward the first connecting tube to accommodate changes in the relative distance between the swing arm 74 and the connecting post 66. In other embodiments, the swing arm 74 can also be a spring or a telescopic rod.

[0054] The advantage of this arrangement is that, in the process of the swing arm 74 driving the connecting column 66 to rotate, the plug shaft 741 is passed through the guide hole 661, and the guide hole 661 is arranged along the radial direction of the connecting column 66, so that the plug shaft 741 can slide along the guide hole 661, so that the plug shaft 741 can adapt to the change in the relative distance between the swing arm 74 and the connecting column 66, thereby avoiding the connecting column 66 interfering with the movement of the swing arm 74.

[0055] like Figure 6 、 Figure 7 As shown, the first mounting seat 61 is connected to the axial hole of the guide column 711 , and the first mounting seat 61 can rotate relative to the guide column 711 .

[0056] The first mounting seat 61 has a connecting hole, and the guide post 711 is inserted into the connecting hole. The first mounting seat 61 can rotate about the axis of the guide post 711, and the massage part 62 rotates with the first mounting seat 61. In one embodiment, there are two first mounting seats 61 and two guide posts 711. The two first mounting seats 61 are located at both ends of the second mounting seat 71, and the two first mounting seats 61 are respectively connected to the guide posts 711 with pins.

[0057] In one embodiment, an elastic connector 712 is disposed between the first mounting seat 61 and the second mounting seat 71. One end of the elastic connector 712 contacts the first mounting seat 61 and exerts a certain elastic force, while the other end of the elastic connector 712 contacts the second mounting seat 71 and exerts a certain elastic force. The elastic connector 712 may be a spring or a torsion spring. During the rotation of the first mounting seat 61, the elastic connector 712 can limit the rotation angle of the first mounting seat 61. When the force on the first mounting seat 61 disappears, the elastic connector 712 resets the first mounting seat 61.

[0058] In another embodiment, a limiting groove is defined on the first mounting seat 61, and a limiting hole is defined on the second mounting seat 71. One end of the elastic connector 712 is inserted into the limiting hole, and the other end of the elastic connector 712 is inserted into the limiting groove. With the two ends of the elastic connector 712 respectively inserted into the limiting hole and the limiting groove, the limiting hole and the limiting groove can limit the elastic connector 712, preventing the elastic connector 712 from slipping out from between the first mounting seat 61 and the second mounting seat 71.

[0059] The advantage of this arrangement is that the first mounting seat 61 is connected to the guide column 711 through a pin, so that the first mounting seat 61 can rotate relative to the guide column 711. When the massage part 62 acts on the human body, the first mounting seat 61 can be adaptively rotated to make the massage part 62 fit the part to be massaged.

[0060] like Figures 1 to 3 As shown, the massage hand also includes a connecting frame 75, and there are multiple connecting components 73, swing arms 74, first mounting seats 61 and massage parts 62 respectively. The driving mechanism 72 is drivingly connected to the connecting frame 75, and the driving mechanism 72 is suitable for driving the connecting frame 75 to perform linear reciprocating motion. All the connecting components 73 are respectively connected to the connecting frame 75, and the connecting components 73 are rotationally connected to at least two of the swing arms 74, and the swing arms 74 are respectively used to drive the massage parts 62 to rotate.

[0061] In one embodiment, there are two connecting assemblies 73 and two first mounting seats 61, and four swing arms 74 and four massage parts 62. The two connecting assemblies 73 are disposed opposite each other and are located at either end of the second mounting seat 71. The two connecting assemblies 73 are screwed or welded to the connecting frame 75. Each connecting assembly 73 is hinged to two swing arms 74, each swing arm 74 is connected to the massage part 62, and each first mounting seat 61 is rotationally connected to two massage parts 62. The two massage parts 62 are disposed opposite each other and are located at either end of the first mounting seat 61. During operation of the driving mechanism 72, the driving mechanism 72 drives the connecting frame 75 to perform linear reciprocating motion, which in turn drives all the connecting assemblies 73 to perform linear reciprocating motion. Each connecting assembly 73 drives two swing arms 74 to rotate, and all the swing arms 74 drive the massage parts 62 to rotate.

[0062] In another embodiment, the connecting frame 75 is provided with a protrusion structure, which protrudes from the upper end surface of the second mounting seat 71, and the driving mechanism 72 is connected to the protrusion structure. Therefore, by providing the protrusion structure on the connecting frame 75, a certain gap is created between the protrusion structure and the second mounting seat 71. On the one hand, it can facilitate the connection between the driving mechanism 72 and the connecting frame 75, and on the other hand, it can prevent the second mounting seat 71 from interfering with the driving of the driving mechanism 72.

[0063] The advantage of such an arrangement is that, through the arrangement of the connecting frame 75, the connecting frame 75 is driven and connected to the driving mechanism 72; the driving mechanism 72 can drive the connecting frame 75 to reciprocate linearly, and all the connecting components 73 are respectively connected to the connecting frame 75, so that the connecting frame 75 can drive all the connecting components 73 to reciprocate linearly, and the connecting components 73 are rotationally connected to at least two of the swing arms 74, so that the connecting component 73 can drive at least two of the swing arms 74 to rotate, so that the driving mechanism 72 can simultaneously drive multiple massage parts 62 to operate synchronously, which on the one hand improves the synchronization of all the massage parts 62, and on the other hand avoids the arrangement of multiple driving mechanisms 72, thereby saving energy and making space utilization more compact.

[0064] An embodiment of the present invention further provides a hair washing machine, comprising the massage hand as described above, wherein the massage hand drives the finger assembly to reciprocately rub the user's hair to achieve cleaning of the user's hair. The hair washing machine also has the beneficial effects of the massage hand, which will not be described in detail here.

[0065] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present invention.
