[0033] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the present application will be further described in detail below with reference to the drawings. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present application.

[0034] Some embodiments of the present application will be described in detail below with reference to the drawings. The features in the following embodiments can be combined with each other without conflict.

[0035]

Massage device

[0036]

Massage core

[0037] The base 5A is used for installing other components of the massage core 5. It has a semi-arc-shaped accommodation groove corresponding to the swing frequency drive motor 5H and the swing amplitude drive motor 5I, and a sliding groove K for the center seat 5D to slide.

[0038] The swing arm 5B is a long strip structure, which is provided with a long hole groove 5B-1 along the length direction thereof.

[0039] The first massage head 5C is installed on the swing arm 5B. The first massage head 5C can be a massage head with heating and lighting functions. The number of the first massage heads 5C on each swing arm 5B can be adjusted according to product design needs.

[0040] The center base 5D has a base portion 5D1 and a sliding portion 5D2, which is located on the upper side of the base portion 5D1. The base portion 5D1 is located in the sliding groove K so that the center base 5D is limited to move within a set range. The sliding portion 5D2 passes through the long hole slot 5B-1 of the swing arm 5B so as to be in sliding cooperation with the swing arm 5B, and is located between the outer end K2 and the inner end K1 of the swing arm 5B and allows the swing arm 5B to rotate thereabout. By adjusting the position of the base portion 5D1 in the sliding groove K, the relative position of the sliding portion 5D2 to the inner end K1 and the outer end K2 of the swing arm 5B can be adjusted, so as to control the swing range of the outer end K2 of the swing arm 5B.

[0041] The swing frequency control member 5E is mounted on the base 5A by a T-shaped pin T1 so as to rotate about a first set center axis. In the present embodiment, the inner ends K1 of the plurality of swing arms 5B are spaced apart along the outer periphery 5M-1 of the adapter base 5M and are rotatably connected to the adapter base 5M (e.g. Figure 9 The adapter base 5M is rotatably connected to the swing frequency control member 5E, specifically, the adapter base 5M is rotatably sleeved on the eccentric rod 5L, which is eccentrically arranged on the swing frequency control member 5E (in the present embodiment, it is integrally formed, but it can also be arranged in separate parts), and the end of the eccentric rod 5L is provided with a cap 5O for limiting the adapter base 5M from being separated from the swing frequency control member 5E, and the cap 5O is retained on the eccentric rod 5L by a fastening screw 5P. The rotation center axis of the adapter base 5M is eccentrically arranged compared with the first set center axis. Since the adapter base 5M can rotate relative to the swing frequency control member 5E, and the swing arm 5B can rotate relative to the adapter base 5M, when the swing frequency control member 5E rotates, each swing arm 5B will not be stuck. The adapter base 5M can be provided with a second massage head (not shown in the figure) so as to make the massage range and massage method of the massage core more comprehensive. Figure 16 In order to make the massage area more comprehensive, in another embodiment, the cap 5O can be provided with a second massage head 5Q, and the cap 5O can be designed to be part of the second massage head 5Q, such as a base of the second massage head 5Q. However, it should be understood that the second massage head 5Q can also be arranged on the adapter base 5M.

[0042] The swing control member 5F rotates around the second set center axis. In this embodiment, the swing control member 5F is sleeved on the swing frequency control member 5E, and the rotation center axes of the swing control member 5F and the swing frequency control member 5E coincide (i.e., the first set center axis and the second set center axis coincide). It should be understood that in another embodiment, the first set center axis and the second set center axis can be designed to be parallel and have a certain spacing, or the two center axes form a certain angle. The swing control member 5F can transform its rotation action into a moving action of the center seat 5D within a set range. Specifically, the swing control member 5F of this embodiment has a guide sliding groove S that is in sliding cooperation with the sliding portion 5D2 of the center seat 5D. The number of guide sliding grooves S corresponds to the number of center seats 5D, and the extension direction of the guide sliding groove S and the moving direction of the center seat 5D have a set angle (the shape and trajectory of the guide sliding groove S are shown in FIG. 6, and the shape and trajectory of the center seat 5D are shown in FIG. 7) Figure 11 ). This angle enables the guide sliding groove S to push the sliding portion 5D2 when the swing control member 5F rotates, so that the center seat 5D can move within a set range. In this embodiment, the swing control member 5F has an inner peripheral portion N1 and an outer peripheral portion N2, the guide sliding groove S is opened on the outer peripheral portion N2, the inner peripheral portion N1 is concave compared to the outer peripheral portion N2, the inner peripheral portion N1 is rotatably sleeved on the swing frequency control member 5E, and the limiting member 5G is arranged on the swing frequency control member 5E. The limiting member 5G limits the swing control member 5F from being separated from the swing frequency control member 5E along the axial direction. By making the inner peripheral portion N1 concave compared to the outer peripheral portion N2, and cooperating with the limiting of the limiting member 5G, the surface of the outer peripheral portion N2 and the limiting member 5G can be substantially flush, so that the overall structure is more compact and light. In order to improve wear resistance, a wear-resistant gasket can be arranged between the swing frequency control member 5E and the swing control member 5F.

[0043] The swing frequency control member 5E is drivingly connected to the swing frequency driving motor 5H through a swing frequency transmission mechanism 5J to be driven to rotate around a set center axis. In this embodiment, the swing frequency transmission mechanism 5J is a double gear, one end of which is a bevel gear (or a worm gear), and the other end of which is a spur gear. The bevel gear (or the worm gear) end of the double gear is engaged with a worm installed on the swing frequency driving motor 5H, and the spur gear end of the double gear is engaged with a peripheral spur gear of the swing frequency control member 5E. It should be understood that the swing frequency transmission mechanism 5J can also be composed of multiple gear transmissions, which will not be described here. The swing amplitude control member 5F is drivingly connected to the swing amplitude driving motor 51 through a swing amplitude transmission mechanism 5K to be driven to rotate. In this embodiment, the swing amplitude transmission mechanism 5K includes a double gear M1 and a rack M2. The rack M2 is an arc-shaped spur gear rack, which is installed and fixed on the swing amplitude control member 5F, and the center of the rack M2 coincides with the rotation center axis of the swing amplitude control member 5F. One end of the double gear M1 is a bevel gear (or a worm gear), and the other end of the double gear M1 is a spur gear. The bevel gear (or the worm gear) end of the double gear M1 is engaged with a worm on the motor shaft of the swing amplitude driving motor 51, and the spur gear end of the double gear M1 is engaged with the rack M2. It should be understood that, unlike the swing frequency control member 5E and the swing amplitude control member 5F in this embodiment, which are driven to rotate by different motors, in another embodiment, the two can be driven by the same motor, and the motor can be drivingly connected to the swing frequency control member 5E and the swing amplitude control member 5F through two transmission mechanism paths, respectively.

[0044] The position detection mechanism 5N is used to detect the rotational displacement of the swing control member 5F. When the swing control member 5F rotates in the forward and reverse directions, the guide slot S on the swing control member 5F can enable the central seat 5D to make reciprocating linear movement in the slot K. In this embodiment, the swing control member 5F is provided with two trigger portions N3, and the position detection mechanism 5N is a micro switch. When the swing control member 5F rotates in the forward or reverse direction to the limit position, the trigger portion N3 will touch the micro switch to trigger the electrical signal. By detecting whether the position detection mechanism 5N is triggered, it can be further detected whether the rotational position of the swing control member 5F is at the limit position, so as to indirectly detect whether the central seat 5D is at the limit position in the slot K. When the central seat 5D is at the limit position in the slot K, the control circuit (not shown in the figure) of the massage core controls the motor to rotate in the forward or reverse direction, so that the central seat 5D will not have the risk of collision in the slot K. The micro switch can also be replaced by a Hall sensor, an optical coupling sensor, or other position detection mechanisms, which will not be described here. The foregoing position detection of the central seat 5D in the slot K can only determine whether it is at the two limit positions. In order to further and more accurately detect the specific position of the central seat 5D in the slot K, a code disc sensor assembly can be arranged on the motor shaft of the swing driving motor 5I to detect the number of rotations of the motor, and then the specific displacement amount of the central seat 5D can be calculated through the gear transmission ratio. When the position detection mechanism 5N is triggered by the electrical signal, it is considered that the central seat 5D is at the starting position. By detecting the specific displacement amount of the central seat 5D according to the foregoing scheme, the specific position of the central seat 5D in the slot K can be accurately known, and thus the relative position of the sliding portion 5D2 and the long hole slot 5B-1 can be known. By controlling the relative position of the sliding portion 5D2 in the long hole slot 5B-1 of the swing arm 5B, the swing amplitude of the first massage head can be accurately controlled, the movement range of the massage head can be wider, and the massage head trajectory can be rich.

[0045] In combination Figure 15 In another embodiment, the massage core of the present application, the inner ends of the plurality of swing arms 5B are stacked and rotatably connected to the swing frequency control member (rotatably sleeved on the eccentric shaft 5L, and the eccentric shaft 5L is eccentrically connected to the swing frequency control member). The rotational center axis of the swing arm 5B is eccentrically arranged compared with the first set center axis. The inner ends 5B1 of the plurality of swing arms 5B are bent compared with the remaining portions 5B2. In this embodiment, the bending degree of the inner ends 5B1 of each swing arm 5B compared with the remaining portions 5B2 gradually increases in turn, so that the remaining portions 5B2 of each swing arm 5B can be substantially on the same plane, Figure 15 The cap installed on the end of the eccentric shaft 5L is omitted, and the cap limits the inner end 5B1 of each swing arm 5B from being separated from the eccentric shaft 5L. In combination Figure 17In Figure 15 Based on the scheme, a second massage head 5Q can be arranged on the cap 50.

[0046] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
