Description

Technical Field

[0001] The utility model relates to the technical field of massagers, in particular to a multifunctional massager with stable operation. Background Art

[0002] For example, some massagers, especially neck and shoulder massagers, mainly adopt an eccentric wheel structure. Some massagers have eccentric wheels respectively arranged at both ends of a rotating shaft. The eccentric wheels are then connected to massage heads for massage. By rotating the rotating shaft, the eccentric wheels are driven to drive the massage heads to swing and knead and massage parts such as the neck and shoulders of the human body. And some massagers set the eccentric wheel on the end face of a gear. The eccentric wheel is then connected to the massage head for massage. By rotating the gear, the eccentric wheel is driven to drive the massage head to swing, so as to achieve the kneading and massaging effect.

[0003] However, the design of the eccentric wheel has defects such as unstable operation and high wear. And, in order to achieve the kneading and massaging effect on the neck and shoulders, the existing massagers often need to design complex reciprocating swing massage mechanisms and circumferential swing massage mechanisms. There are many components, and there are problems such as difficult assembly. Summary of the Utility Model

Detailed implementation manners

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0045] As Figures 1 to 10 shown, a multifunctional massager with stable operation of the present utility model includes a first massage component 1, a second massage component 2, a driving component 3, a transmission component 4, a control component 5, and a housing 6.

[0046] The first massage component 1 is installed on the housing 6 of the massager, and the first massage component 1 can perform reciprocating swing massage.

[0047] As Figure 1 and Figure 2 shown, the first massage component 1 includes a first swing arm 11, a first swing rod 12, and a first rotating wheel 13;

[0048] The first rotating wheel 13 is rotatably installed in the housing 6 along the horizontal direction. A first spherical surface groove 131 is provided at the top of the first rotating wheel 13, and a first eccentric inclined hole 132 is provided in the first spherical surface groove 131;

[0049] The first swing arm 11 is movably mounted on the upper side of the housing 6. The outer end of the first swing arm 11 is far from the housing 6, and a first massage head 111 is provided at the outer end of the first swing arm 11. The inner end of the first swing arm 11 extends into the housing 6, and a spherical first rotating portion 112 is provided at the inner end of the first swing arm 11. The lower part of the first rotating portion 112 is hemispherical and is rotatably fitted into the first spherical groove 131 of the first rotating wheel 13.

[0050] Refer to Figure 5 and Figure 10 , a swing rod groove 113 is recessed in the bottom surface of the lower part of the first rotating portion 112. The upper end of the first swing rod 12 is hinged in the swing rod groove 113. The first swing rod 12 can swing left and right in the swing rod groove 113, and the lower end of the first swing rod 12 extends out of the swing rod groove 113 and extends into the first eccentric inclined hole 132.

[0051] First limiting columns 114 extend left and right from the left and right sides of the first rotating portion 112 respectively. Two first limiting grooves 71 are provided on the housing 6, and the two first limiting grooves 71 are respectively for inserting the two first limiting columns 114 to limit the rotation angle of the first rotating portion 112 of the first swing arm 11. In this embodiment, the left and right rotation of the first rotating portion 112 is mainly limited, and at the same time, the first rotating portion 112 is restricted from disengaging from the housing 6 upward.

[0052] In this embodiment, the first limiting groove 71 can be recessed in the bottom surface of the first limiting cover plate 7, and the first limiting cover plate 7 can be locked above the first opening 611 provided on the top surface of the housing 6 for the first swing arm 11 to extend out.

[0053] With this structure, when the first rotating wheel 13 rotates, it can drive the lower end of the first swing rod 12 to perform a horizontal circular motion. Since the upper end of the first swing rod 12 is inserted into the swing rod groove 113, it has a tendency to drive the first rotating portion 112 to perform a horizontal circular motion. However, since the first limiting column 114 of the first rotating portion 112 is restricted by the first limiting groove 71 and cannot rotate left and right, and the swing rod groove 113 allows the first swing rod 12 to swing left and right, the original horizontal circular motion that the first rotating portion 112 needs to perform is decomposed and converted into the front and back reciprocating rotation of the first rotating portion 112 and the left and right reciprocating swing of the first swing rod 12. The front and back reciprocating rotation of the first rotating portion 112 drives the first swing arm 11 to swing back and forth. That is, the rotation of the first rotating wheel 13 can finally achieve the back and forth reciprocating swing of the first swing arm 11, so that the first massage head 111 at the outer end of the first swing arm 11 realizes the back and forth reciprocating swing massage.

[0054] Moreover, the spherical fit between the first rotating portion 112 and the first rotating wheel 13 can reduce wear and improve the running stability. At the same time, the structure of the first massage assembly 1 is simple and convenient to assemble.

[0055] In this embodiment, the first swing arm 11 can be arc-shaped, with the two ends of the arc being the first massage head 111 and the first rotating part 112 respectively. Moreover, a limiting part 72 can be provided at the top of the first limiting cover plate 7 to limit the range within which the first swing arm 11 can swing back and forth, and this range can be adjusted according to actual needs.

[0056] In this embodiment, the first limiting post 114 can be cylindrical, and the first limiting groove 71 can be a circular groove, such that the first limiting post 114 can rotate back and forth along with the first rotating part 112, and can further improve the rotational stability of the first rotating part 112.

[0057] Specifically, as Figure 2 、 Figure 9 and Figure 10 shown, the upper end of the first swing rod 12 has a hinge part 121, and a hinge hole 1211 that penetrates through from front to back is provided on the hinge part 121, and this hinge part 121 is located within the swing rod groove 113; a shaft hole 115 that communicates with the swing rod groove 113 forward is provided at the rear side of the first rotating part 112, and a pin rotating shaft 116 is fixedly inserted through the shaft hole 115, and this pin rotating shaft 116 simultaneously passes through the hinge hole 1211 of the hinge part 121; in this way, the first swing rod 12 can rotate along the pin rotating shaft 116, and at the same time, it is convenient for the assembly of the product; and the left and right width of the first swing rod 12 is less than the left and right width of the swing rod groove 113, so as to facilitate the left and right swing of the first swing rod 12.

[0058] In this embodiment, the left and right width of the upper part of the swing rod groove 113 is less than the left and right width of the lower part of the swing rod groove 113, and it can be approximately fan-shaped, so that the first swing rod 12 can have sufficient swing space and ensure that the strength of the first rotating part 112 is sufficient.

[0059] At the same time, the part of the lower end of the first swing rod 12 extending into the first eccentric inclined hole 132 can be a circular rod, and the upper end of the first swing rod 12 can have front and rear planes. Similarly, the front and rear side walls of the swing rod groove 113 can be planes, which is convenient for the upper end of the first swing rod 12 to be installed into the swing rod groove 113 and for the pin rotating shaft 116 to pass through.

[0060] As Figure 1 and Figure 2 shown, the housing 6 in this embodiment includes an upper housing 61 and a lower housing 62. The upper housing 61 and the lower housing 62 are covered up and down to form a housing space 63, and the housing space 63 is used to install the drive assembly 3, the transmission assembly 4, the control assembly 5, the first rotating wheel 13 and the second rotating wheel 23 described below.

[0061] One first massage assembly 1 and one second massage assembly 2 are provided at the front and rear intervals on the left side of the massager, and another first massage assembly 1 and another second massage assembly 2 are provided symmetrically on the right side of the massager with respect to the left side layout.

[0062] The second massage component 2 includes a second swing arm 21, a second swing rod 22, and a second rotating wheel 23;

[0063] The second rotating wheel 23 is rotatably mounted in the housing 6 in the horizontal direction. A second spherical groove 231 is provided at the top of the second rotating wheel 23, and a second eccentric inclined hole 232 is provided in the second spherical groove 231;

[0064] The second swing arm 21 is movably mounted on the upper side of the housing 6. The outer end of the second swing arm 21 is far from the housing 6, and a second massage head 211 is provided at the outer end of the second swing arm 21; the inner end of the second swing arm 21 extends into the housing 6, and the inner end of the second swing arm 21 has a spherical second rotating portion 212. The lower part of the second rotating portion 212 is hemispherical and is rotatably fitted into the second spherical groove 231 of the second rotating wheel 23;

[0065] The upper end of the second swing rod 22 is inserted upward into the lower part of the second rotating portion 212, and the lower end of the second swing rod 22 extends downward into the second eccentric inclined hole 232;

[0066] Second limiting columns 213 extend respectively in the front and rear directions on the front and rear sides of the second rotating portion 212. Two second limiting grooves 612 are provided on the housing 6, and the two second limiting grooves 612 are respectively for inserting the two second limiting columns 213, so as to limit the rotation angle of the second rotating portion 212. In this embodiment, it mainly limits the second rotating portion 212 from disengaging from the housing 6 upward and enables the second rotating portion 212 to rotate slightly left and right.

[0067] In this embodiment, the second limiting grooves 612 can be provided on the front and rear sides of a second opening 613 provided on the housing 6, and the second swing arm 21 extends out from the second opening 613.

[0068] The bottom of the first rotating wheel 13 has a first rotating shaft 133, and the first rotating shaft 133 is rotatably inserted into a first installation groove 621 provided inside the housing 6. The bottom of the second rotating wheel 23 has a second rotating shaft 233, and the second rotating shaft 233 is rotatably inserted into a second installation groove 622 provided inside the housing 6.

[0069] With this structure, when the second rotating wheel 23 rotates, it can drive the lower end of the second swing rod 22 to perform a horizontal circular motion, and the upper end of the second swing rod 22 drives the second rotating portion 212 to perform a horizontal circular motion, and the horizontal circular motion of the second rotating portion 212 drives the second swing arm 21 to perform a horizontal circular motion. That is, the rotation of the second rotating wheel 23 can make the second massage head 211 at the outer end of the first swing arm 11 perform a swinging massage of horizontal circular motion.

[0070] In this embodiment, the second limiting post 213 can be semi-cylindrical, the top surface of the second limiting post 213 is an arc surface, and the second limiting groove 612 can be a long groove extending vertically. The second limiting post 213 can perform a yielding movement of rising and falling in the second limiting groove 612 along with the horizontal circular movement of the second rotating part 212, and at the same time, it can also maintain the stability of the movement of the second rotating part 212.

[0071] The second massage head 211 in this embodiment can be in the shape of a "peanut" to improve the massage effect. Moreover, the second rotating part 212 and the second rotating wheel 23 are in spherical cooperation, which can reduce wear and improve the running stability. At the same time, the structure of the second massage assembly 2 is simple and convenient to assemble.

[0072] Thus, the massager of this embodiment is provided with two first massage assemblies 1 and two second massage assemblies 2. It can utilize the reciprocating swing massage of the first massage assembly 1 and the horizontal circular movement massage of the second massage assembly 2 to achieve the kneading massage effect on the user's shoulder and neck parts, and can run stably and reliably, effectively relieve the user's physical fatigue, and improve the user experience.

[0073] As Figure 2 、 Figure 7 and Figure 8 shown, the driving assembly 3, the transmission assembly 4 and the control assembly 5 are installed inside the housing 6.

[0074] The driving assembly 3 is in transmission connection with the first rotating wheel 13 and the second rotating wheel 23 through the transmission assembly 4 to drive the first rotating wheel 13 and the second rotating wheel 23 to rotate.

[0075] Specifically, the driving assembly 3 is a driving motor 31, the driving motor 31 is installed at the middle position inside the housing 6, and driving ends 311 are respectively provided at the left and right ends of the driving motor 31; the transmission assembly 4 includes two worm gears 41 and two transmission wheels 42, and the two worm gears 41 are respectively connected to the driving ends 311 at the left and right ends of the driving motor 31; the two transmission wheels 42 are distributed left and right, and are both horizontally rotatably installed between the first rotating wheel 13 and the second rotating wheel 23 on the same side; the transmission wheel 42 includes a coaxial turbine 421 and a transmission gear 422; the first rotating wheel 13 and the second rotating wheel 23 are provided with gear structures 8; the turbine 421 of the transmission wheel 42 meshes with the worm gear 41 on the same side, and the transmission gears 422 of the transmission wheel 42 respectively mesh with the first rotating wheel 13 and the second rotating wheel 23 on the same side.

[0076] Thus, the drive motor 31 can drive the worm 41 to rotate. The worm 41 drives the engaged turbine 421 to rotate horizontally, and the transmission gear 422 coaxial with the turbine 421 rotates synchronously, which can drive the first rotating wheel 13 and the second rotating wheel 23 to rotate, realizing the synchronous movement of the first swing arm 11 of the first massage assembly 1 and the second swing arm 21 of the second massage assembly 2.

[0077] The control assembly 5 includes a control circuit board 51 and a battery 52; both the control circuit board 51 and the battery 52 are electrically connected to the drive motor 31; the control circuit board 51 can be used to control the battery 52 to supply power to the drive motor 31 and control the operation of the drive motor 31 to realize the opening and closing of the massage function and the adjustment of the massage intensity, etc.
