[0018] In order to clarify the objectives, technical means and advantages of the embodiments of the present invention, the present invention will be described in more detail below with reference to the drawings. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various ways. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without the need for creative work are all within the scope of protection of the present invention.

[0019] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, several embodiments of the present invention will be described in detail with reference to the accompanying drawings. Unless a contradiction occurs, the features of the following embodiments can be combined with each other.

[0020] <Massage device> 1 to 3, in one embodiment, the massager of the present application includes an upper case 1, a lower case 2, a soft cloth 3, a strap 4, and a massage machine core 5. The massager of this embodiment is used to massage a user's limbs. The upper case 1 is provided with a display and operation buttons. The lower case 2 is connected to the upper case 1. The soft cloth 3 is attached to the lower case 2. The strap 4 is attached between the upper case 1 and the lower case 2. The strap 4 may be an elastic band or may have Velcro, but only a portion of the strap 4 is shown in the figure. The massage machine core 5 can be attached to the upper case 1 with a screw post. When the massage machine core 5 is operated, it massages the user via the soft cloth 3. The soft cloth 3 may be replaced with a soft rubber material, such as silicone, to provide waterproofing.

[0021] <Massage Machine Core> 4 to 14, the massage machine core 5 according to one embodiment of the present invention includes a base 5A, a swing arm 5B, a first massage head 5C, a center base 5D, a swing frequency control member 5E, a swing width control member 5F, a regulating member 5G, a swing frequency drive motor 5H, a swing width drive motor 5I, a swing frequency transmission mechanism 5J, a swing width transmission mechanism 5K, an eccentric connecting member 5L, an adapter 5M, and a position detection mechanism 5N. The swing arm 5B, the first massage head 5C, and the center base 5D are arranged in a plurality of corresponding sets.

[0022] The base 5A is used to mount other components of the massage machine core 5, and has a semicircular arc-shaped storage tank corresponding to the oscillation frequency drive motor 5H and the oscillation width drive motor 5I, and a slide groove K along which the center base 5D slides.

[0023] The swing arm 5B has an elongated structure, and is provided with a long hole tank 5B-1 along its length.

[0024] The first massage heads 5C are attached to the swing arms 5B. The first massage heads 5C may be massage heads with heating and light-emitting functions. The number of first massage heads 5C on each swing arm 5B can be adjusted according to the needs of the product design.

[0025] The center base 5D has a base portion 5D1 and a sliding portion 5D2. The sliding portion 5D2 is located above the base portion 5D1. The base portion 5D1 is located within the slide groove K and restricts the center base 5D to move within a set range. The sliding portion 5D2 penetrates the elongated groove 5B-1 of the swing arm 5B and is slidably fitted to the swing arm 5B. The sliding portion 5D2 is located between the outer end K2 and the inner end K1 of the swing arm 5B, allowing the swing arm 5B to rotate around the sliding portion 5D2. By adjusting the position of the base portion 5D1 within the slide groove K, the relative positions of the sliding portion 5D2 and the inner end K1 and outer end K2 of the swing arm 5B can be adjusted. This controls the swing width of the outer end K2 of the swing arm 5B.

[0026] The oscillation frequency control member 5E is attached to the base 5A by a T-shaped pin part T1, thereby rotating around a first set central axis. In this embodiment, the inner ends K1 of the multiple oscillation arms 5B are spaced apart along the outer periphery 5M1 of the adapter 5M and are all rotatably connected to the adapter 5M (as shown in FIG. 9, they are rotatably connected by a U-shaped pin part T2). The adapter 5M is rotatably connected to the oscillation frequency control member 5E. Specifically, the adapter 5M is rotatably fitted onto an eccentric rod 5L. The eccentric rod 5L is eccentrically provided on the oscillation frequency control member 5E (in this embodiment, it is integrally molded, but it may be formed as a separate part). A cap 5O is provided at the end of the eccentric rod 5L to prevent the adapter 5M from being removed from the oscillation frequency control member 5E. The cap 5O is held to the eccentric rod 5L by a fastening screw 5P. The rotation center axis of the adapter 5M is eccentric with respect to the first set center axis. Because the adapter 5M is rotatable relative to the oscillation frequency control member 5E and the oscillation arms 5B are rotatable relative to the adapter 5M, the oscillation arms 5B do not become jammed when the oscillation frequency control member 5E rotates. By providing a second massage head (not shown) on the adapter 5M, the massage range and massage technique of the massage machine core can be more comprehensive. Referring to FIG. 16, in other embodiments, a second massage head 5Q may be provided on the cap 5O to provide a more omnidirectional massage area. The cap 5O may also be designed as a part of the second massage head 5Q, for example, to function as a base for the second massage head 5Q. However, it should be understood that the second massage head 5Q may also be provided on the adapter 5M or 5L.

[0027] The oscillation width control member 5F rotates around the second set central axis. In this embodiment, the oscillation width control member 5F is fitted to the oscillation frequency control member 5E. The rotation central axes of the oscillation width control member 5F and the oscillation frequency control member 5E are aligned (i.e., the first set central axis and the second set central axis are aligned). However, it should be understood that in other embodiments, the first set central axis and the second set central axis may be designed to be parallel and spaced apart, or may be designed to form a fixed angle. The oscillation width control member 5F can convert its own rotation into the movement of the center base 5D within a set range. Specifically, the oscillation width control member 5F in this embodiment has a guide groove S into which the sliding contact portion 5D2 of the center base 5D is slidably fitted. The number of guide grooves S corresponds to the number of center bases 5D, and the extension direction of the guide grooves S and the movement direction of the center base 5D form a predetermined angle (see Figure 11 for the shape and trajectory of the guide grooves S). The existence of this angle allows the guide grooves S to push and move the sliding contact portion 5D2 when the oscillation width control member 5F rotates, thereby allowing the center base 5D to move within a set range. In this embodiment, the oscillation width control member 5F has an inner peripheral portion N1 and an outer peripheral portion N2. The guide groove S is provided on the outer peripheral portion N2. The inner peripheral portion N1 is recessed more than the outer peripheral portion N2 and is rotatably fitted to the oscillation frequency control member 5E. The regulating member 5G is provided on the oscillation frequency control member 5E and regulates the separation of the oscillation width control member 5F from the oscillation frequency control member 5E in the axial direction. By recessing the inner peripheral portion N1 relative to the outer peripheral portion N2 and restricting it with the restricting member 5G, the surfaces of the outer peripheral portion N2 and the restricting member 5G can be made substantially flush, making the overall structure more compact and thinner. To improve wear resistance, a wear-resistant washer may be provided between the oscillation frequency control member 5E and the oscillation width control member 5F.

[0028] The oscillation frequency control member 5E is driven to rotate around a set central axis by being operably connected to the oscillation frequency drive motor 5H via an oscillation frequency transmission mechanism 5J. In this embodiment, the oscillation frequency transmission mechanism 5J is a double gear, one end of which is a helical gear (or worm wheel) and the other end of which is a spur gear. The helical gear (or worm wheel) at one end of the double gear meshes with a worm provided on the oscillation frequency drive motor 5H. The spur gear at the other end of the double gear meshes with the outer circumferential spur tooth portion of the oscillation frequency control member 5E. However, it should be understood that the oscillation frequency transmission mechanism 5J may be configured using a multi-stage gear transmission, but detailed description thereof will be omitted here. The oscillation width control member 5F is driven to rotate by being operably connected to the oscillation width drive motor 5I via an oscillation width transmission mechanism 5K. In this embodiment, the oscillation width transmission mechanism 5K includes a double gear M1 and a rack M2. The rack M2 is an arc-shaped spur-tooth rack fixed to the oscillation width control member 5F. The center of the rack M2 coincides with the rotation axis of the oscillation width control member 5F. The duplex gear M1 has a helical gear (or worm wheel) at one end and a spur gear at the other end. The helical gear (or worm wheel) at one end meshes with a worm attached to the motor shaft of the oscillation width drive motor 5I, and the spur gear at the other end meshes with the rack M2. However, unlike this embodiment in which the oscillation frequency control member 5E and the oscillation width control member 5F are driven by different motors, in other embodiments, both can be driven by the same motor. In this case, it should be understood that the motor is transmissively connected to the oscillation frequency control member 5E and the oscillation width control member 5F, respectively, via two transmission mechanism paths.

[0029] The position detection mechanism 5N is used to detect the rotational displacement of the oscillation width control member 5F. When the oscillation width control member 5F rotates forward and backward, the guide groove S allows the center base 5D to move linearly back and forth within the slide groove K. In this embodiment, the oscillation width control member 5F is provided with two trigger members N3. The position detection mechanism 5N is a microswitch. When the oscillation width control member 5F rotates forward or backward and reaches its limit position, the trigger member N3 contacts the microswitch and triggers an electrical signal. Whether the position detection mechanism 5N is triggered can be used to detect whether the rotation position of the oscillation width control member 5F is at its limit position, which indirectly detects whether the center base 5D is at its limit position within the slide groove K. When the center base 5D is at its limit position within the slide groove K, the massage machine core's control circuit (not shown) controls the forward or reverse rotation of the motor, thereby eliminating the risk of the center base 5D colliding with the slide groove K. The microswitch may be replaced with a position detection mechanism such as a Hall sensor or photocoupler sensor, but a detailed description thereof will be omitted here. The aforementioned detection of whether the center base 5D is positioned within the slide groove K can only determine whether it is at one of two limit positions. To more accurately detect the specific position of the center base 5D within the slide groove K, an encoder sensor assembly is installed on the motor shaft of the oscillation width drive motor 5I to detect the number of motor rotations and further estimate the specific displacement of the center base 5D through the gear transmission ratio. When the position detection mechanism 5N triggers an electrical signal, it is determined that the center base 5D is at the starting position. By detecting the specific displacement of the center base 5D through the aforementioned scheme, the specific position of the center base 5D in the slide groove K can be accurately determined, and therefore the relative positions of the sliding contact portion 5D2 and the slotted groove 5B-1 can be determined. By controlling the relative position of the sliding contact portion 5D2 in the long-hole tank 5B-1 of the swing arm 5B, the swing width of the first massage head can be accurately controlled, making the range of motion of the massage head more wide and controllable according to needs, thereby realizing a variety of trajectories of the massage head.In another embodiment, the same function as above can be realized by attaching an encoder sensor assembly to the oscillation width control member 5F and directly detecting the number of rotations of the oscillation width control member 5F, but a detailed description thereof will be omitted.

[0030] Referring to FIG. 15, in another embodiment of the massage machine core of the present application, the inner ends of multiple swing arms 5B are stacked and each is rotatably connected to a swing frequency control member (each is rotatably fitted onto an eccentric rod 5L, and the eccentric rod 5L is eccentrically connected to the swing frequency control member). The swing arms 5B have their rotation axes eccentrically positioned relative to a first set center axis. The inner ends 5B1 of the multiple swing arms 5B are bent relative to the other portions 5B2. In this embodiment, the bending degree of the inner ends 5B1 of each swing arm 5B relative to the other portions 5B2 is gradually increased, so that the other portions 5B2 of each swing arm 5B are positioned approximately flush with each other. FIG. 15 does not show the caps attached to the ends of the eccentric rods 5L. The caps prevent the inner ends 5B1 of each swing arm 5B from separating from the eccentric rod 5L. Referring to FIG. 17, based on the technical solution shown in FIG. 15, a second massage head 5Q may be provided on the cap 5O.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto, and any modifications or replacements that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be in accordance with the scope of protection of the claims.
