Description

Technical Field

[0001] This application relates to the field of massage technology, and in particular to a massage mechanism and a waist massager. Background Technology

[0002] For discomforts such as lower back fatigue and soreness caused by prolonged sitting, more and more people are using lower back massagers to massage their lower backs and achieve relief.

[0003] In related technologies, lumbar massagers typically include a waist belt and a massage mechanism mounted on the belt. The massage mechanism has massage heads exposed outside the belt, allowing the user's waist to be massaged through the movement of the massage heads. Furthermore, to further alleviate lumbar discomfort, phototherapy devices are usually incorporated into the massage heads. However, current phototherapy devices have a small phototherapy range, resulting in a limited area of ​​phototherapy applied to the massaged area and thus poor phototherapy effects.

[0032] As an optional implementation, in an embodiment of the first aspect of this application, the plurality of massage heads includes two first massage heads and two second massage heads. The two first massage heads are respectively disposed at both ends of the core housing in the first direction, and the two second massage heads are spaced apart between the two first massage heads along the first direction. The two first massage heads and the two second massage heads are all connected to the power assembly through the swing rod.

[0037] Compared with the prior art, the beneficial effects of this application are:

[0038] The massage mechanism provided in this application includes multiple massage heads connected to a power assembly via a swing arm. The first end of the swing arm is movably connected to the mechanism housing, and the second end is connected to the massage head. Driven by the power assembly, the swing arm oscillates around the first end, causing the massage heads to oscillate. This allows adjacent massage heads 201 to move closer or further apart along a first direction. Compared to the reciprocating oscillation of massage heads in a plane parallel to the skin surface of the massage mechanism in related technologies, when two massage heads move to their furthest point and then approach each other, the swing arm's length direction intersects the skin surface. The massage heads then oscillate in an arc shape on the side near the skin surface, making it easier for the two massage heads to pinch and massage the skin, thus achieving a more comfortable pinching effect. Meanwhile, since at least two phototherapy components are placed on at least two massage heads that are close to or far apart from each other, the light emitted by the phototherapy components changes when the massage heads oscillate. When the two massage heads are close to each other, the light emitted by each phototherapy component will shine inward along with the massage head, which can provide concentrated phototherapy to the massage area on the inner side. When the two massage heads are far apart, the light emitted by each phototherapy component will diffuse outward along with the massage head. As a result, the area illuminated by the phototherapy components on the two massage heads is larger, which can provide phototherapy to a larger area of ​​massage, thereby expanding the range of phototherapy of the massage mechanism and improving the effect of phototherapy.

[0068] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0069] Please see Figure 1 and Figure 2This application discloses a massage mechanism 100, including a mechanism housing 10, a massage mechanism 20, and a drive mechanism 30. The mechanism housing 10 has a skin-friendly surface 10a. The massage mechanism 20 includes a plurality of massage heads 201 movably disposed on the mechanism housing 10. The plurality of massage heads 201 are spaced apart along a first direction X and located on the side of the skin-friendly surface 10a. The drive mechanism 30 includes a power component 31 and a plurality of swing arms 32 connected to the power component 31. Each swing arm 32 has a first end 32a and a second end 32b opposite to each other along its length direction. The length direction of each swing arm 32 intersects the skin-friendly surface 10a. Each first end 32a is movably connected to the mechanism housing 10, and each second end 32b is connected to a massage head. Each swing arm 32 swings around the first end 32a under the drive of the power component 31, thereby causing each massage head 201 to swing, so that any two adjacent massage heads 201 can move closer to each other or further away from each other along the first direction X.

[0070] It should be noted that the skin-proximal surface 10a of the mechanism housing 10 refers to the surface of the massage mechanism 100 facing the user's skin during use. Therefore, by placing multiple massage heads 201 of the massage mechanism 20 on the side of the skin-proximal surface 10a, the massage heads 201 can massage the user. Furthermore, the length direction of each swing arm 32 intersects the skin-proximal surface 10a; that is, the length direction of each swing arm 32 is angled to the skin-proximal surface 10a. Compared to when the length direction of each swing arm 32 is parallel to the skin-proximal surface, causing the massage head to swing in a plane parallel to the skin-proximal surface 10a, the swing arm 32 arrangement in this application allows the massage head 201 to swing within the space on the side of the skin-proximal surface 10a.

[0071] It can be understood that, under the action of the power component 31, the movement directions of any two adjacent swing arms 32 in the first direction X are opposite, so that any two adjacent massage heads move closer or further apart from each other along the first direction X.

[0072] Optionally, the core housing 10 can be generally elongated, and the first direction X can be the length direction of the core housing 10. Multiple massage heads 201 are spaced apart along the length direction of the core housing 10, which can provide more space for the massage heads 201, thereby enabling the massage mechanism 20 to have a larger massage range.

[0073] The massage mechanism 100 provided in this application has a first end 32a of a swing arm 32 movably connected to the mechanism housing 10, and a second end 32b connected to a massage head. This allows the swing arm 32 to swing around the first end 32a under the drive of the power component 31, thereby causing the massage head 201 to swing. This allows adjacent massage heads 201 to move closer or further apart along the first direction X. Compared to the way massage heads 201 swing in a plane parallel to the skin surface 10a in related technologies, because the length direction of the swing arm 32 in this application intersects with the skin surface 10a, the movement of adjacent massage heads 201 moving closer or further apart along the first direction X occurs within the space on the side of the skin surface 10a. The massage heads 201 change height during the movement. This allows the two massage heads 201 to more easily pinch and knead the skin of the massage area when they reach their furthest point and then move closer together, thus achieving a more comfortable pinching effect.

[0074] In order to enable the massage mechanism 100 to have a better phototherapy effect under the above-mentioned movement mode of the massage head 201, in some possible embodiments, the massage mechanism 100 may also include a plurality of phototherapy components 40. At least two massage heads 201 that are close to or far from each other are provided with phototherapy components 40. The phototherapy components 40 swing under the swing of the massage head 201 to change the direction of the light emitted by the phototherapy components 40.

[0075] By arranging phototherapy components 40 on at least two massage heads 201 that are close to or far apart, the light emitted by the phototherapy components 40 changes when the massage heads 201 oscillate. When the two massage heads 201 are close together, the light emitted by each phototherapy component 40 illuminates the inner side between the two adjacent massage heads 201, allowing for concentrated phototherapy to the massage area on the inner side. When the two massage heads 201 are far apart, the light emitted by each phototherapy component 40 diffuses outwards from the two adjacent massage heads 201. This results in a larger area illuminated by the phototherapy components 40 on the two massage heads 201, allowing for phototherapy to a wider range of massage areas. This expands the range of phototherapy provided by the massage mechanism 100 and enhances the phototherapy effect.

[0076] It should be noted that at least two massage heads 201, which are close to or far apart from each other, are equipped with phototherapy components 40. While achieving a massage effect, these components can also emit different colors of light to achieve multi-dimensional effects, from surface skincare to deep tissue repair. Users can select different colors of light according to their needs (e.g., exercise recovery, chronic pain, or skin care). For example, infrared light can be used to assist in muscle repair and joint inflammation relief; near-infrared light can be used for deep muscle / ligament repair or nerve pain management; and blue light can be used for acne treatment and skin soothing.

[0077] Optionally, the number of massage heads 201 can be two, four, or six, etc. Taking four massage heads 201 as an example, the four massage heads 201 can be arranged sequentially at intervals along the first direction X. Since any two adjacent massage heads 201 can move closer or further apart along the first direction X, the first massage head 201 and the second massage head 201 can move closer or further apart along the first direction X, the second massage head 201 and the third massage head 201 can move closer or further apart along the first direction X, and the third massage head 201 and the fourth massage head 201 can move closer or further apart along the first direction X. Specifically, when the first massage head 201 and the second massage head 201 are farthest apart, the second massage head 201 and the third massage head 201 are closest together, and the third massage head 201 and the fourth massage head 201 are farthest apart. Then, each of the first to fourth massage heads 201 is equipped with a phototherapy component 40. At this time, the phototherapy components 40 on the first and second massage heads 201 emit light to the outside of the two massage heads 201, the phototherapy components 40 on the second and third massage heads 201 emit light to the inside between the two massage heads 201, and the phototherapy components 40 on the third and fourth massage heads 201 emit light to the outside of the two massage heads 201.

[0078] Continue reading Figure 1 and Figure 2 In some possible embodiments, the plurality of massage heads 201 includes two first massage heads 21 and two second massage heads 22. That is, the massage mechanism in this application includes four massage heads. The two first massage heads 21 are respectively disposed at both ends of the core housing 10 in the first direction X. The two second massage heads 22 are spaced apart between the two first massage heads 21 along the first direction X. The two first massage heads 21 and the two second massage heads 22 are all connected to the power assembly 31 through the swing rod 32. The adjacent first massage heads 21 and second massage heads 22 move closer or further away from each other along the first direction X under the action of the power assembly 31 and the swing rod 32.

[0079] In some possible implementations, each of the two first massage heads 21 is provided with a phototherapy component 40, and when the two first massage heads 21 are close to each other, the light emitted by the phototherapy components 40 of the two first massage heads 21 converges between them.

[0080] It is understood that the massage mechanism 20 may include four massage heads, which can be divided into two massage groups. The two massage groups can be arranged at intervals along the first direction X. Each massage group may include a first massage head 21 and a second massage head 22. The first massage head 21 and the second massage head 22 of each massage group can swing closer to each other or further away along the first direction X. Thus, the massage mechanism 20 of this application can perform a large-area massage by using the four massage heads. When the massage heads move closer to each other, they can pinch a larger area of ​​muscles, further increasing the massage range and achieving a comprehensive massage effect.

[0081] Especially when used for waist massage, the two sets of first massage heads 21 and second massage heads 22 can be located on the left and right sides of the waist respectively, and pinch and massage the erector spinae muscles on the left and right sides of the waist respectively. At the same time, the waist can be massaged in all directions. Since the phototherapy component 40 is set on the two massage heads (i.e. the two first massage heads 21) on the outside, the area irradiated by the phototherapy component 40 can be maximized and the phototherapy range can be expanded.

[0082] Optionally, the length directions of the two first massage heads 21 and the two second massage heads 22 are parallel to the skin surface 10a and are set at an angle to the first direction X, for example, at 80°, 85° or 90°. That is, the extension directions of the two first massage heads 21 and the two second massage heads 22 are not only parallel to the skin surface 10a, but also at an angle to the first direction X.

[0083] With two first massage heads 21 and two second massage heads 22 on the housing 10 of the mechanism, which can perform a large-area massage, the massage heads are set at an angle relative to the first direction X, so that the length direction of the massage heads does not extend along the first direction X. This makes the long strip-shaped massage heads have a larger kneading range, which can better gather the muscles and gather a larger area of ​​muscles, making the massage range wider. Furthermore, during the swinging of the two first massage heads 21, the area swept by the light emitted by the phototherapy component 40 is further increased, resulting in a larger massage range and a larger area covered by the light.

[0084] In some possible implementations, in two massage heads 201, each equipped with a phototherapy component 40, one massage head 201 is configured as a first sub-massage head 20a, the other massage head 201 is configured as a second sub-massage head 20b, the swing arm 32 connected to the first sub-massage head 20a is configured as a first sub-swing arm 32c, and the swing arm 32 connected to the second sub-massage head 20b is configured as a second sub-swing arm 32d.

[0085] Combination Figure 3 The diagram illustrates the farthest distance between the first sub-massage head 20a and the second sub-massage head 20b. In this diagram, O1 is the extension line of the axis of the swing arm 32 (first sub-swing arm 32c) connected to the first sub-massage head 20a, and O2 is the extension line of the axis of the swing arm 32 (second sub-swing arm 32d) connected to the second sub-massage head 20b. In some possible implementations, when the first sub-massage head 20a and the second sub-massage head 20b are moved away from each other to their maximum distance, the extended lines of the axes of the first sub-swing arm 32c and the second sub-swing arm 32d intersect, and the point of intersection is located on the side away from the skin surface 10a. That is, the extended lines of the axes of the swing arm 32 (first sub-swing arm 32c) connected to the first sub-massage head 20a and the extended lines of the axes of the swing arm 32 (second sub-swing arm 32d) connected to the second sub-massage head 20b are diverging on the side near the skin surface 10a and contracting on the side away from the skin surface 10a. If they continue to extend in this direction, O1 and O1 will intersect at a point.

[0086] When the extended lines of the axes of the first sub-oscillating arm 32c and the second sub-oscillating arm 32d intersect, and the intersection point is located on the side away from the skin surface 10a, the light emitted by the phototherapy component 40 of the first sub-massage head 20a and the light emitted by the phototherapy component 40 of the second sub-massage head 20b spreads out on the outer side of the first sub-massage head 20a and the second sub-massage head 20b, so that the phototherapy component 40 can sweep over a larger area of ​​massage area to achieve the maximum phototherapy range.

[0087] In other possible implementations, combined with Figure 4This diagram illustrates the closest possible distance between the first sub-massage head 20a and the second sub-massage head 20b. O3 represents the extension of the axis of the swing arm 32 (first sub-swing arm 32c) connected to the first sub-massage head 20a, and O4 represents the extension of the axis of the swing arm 32 (second sub-swing arm 32d) connected to the second sub-massage head 20b. When the first and second sub-massage heads 20a and 20b are at their minimum distance, the extensions of the axes of the first and second sub-swing arms 32c and 32d intersect, and the point of intersection is located on the side near the skin surface 10a. That is, the extensions of the axes of the swing arm 32 (first sub-swing arm 32c) connected to the first sub-massage head 20a and the swing arm 32 (second sub-swing arm 32d) connected to the second sub-massage head 20b converge on the side near the skin surface 10a. If extended further in this direction, O3 and O4 will intersect at a single point.

[0088] When the extended lines of the axes of the first sub-oscillating arm 32c and the second sub-oscillating arm 32d intersect, and the intersection point is located on the side near the skin surface 10a, the light emitted by the phototherapy component 40 of the first sub-massage head 20a and the light emitted by the phototherapy component 40 of the second sub-massage head 20b converge between the first sub-massage head 20a and the second sub-massage head 20b, so that the phototherapy component 40 can concentrate phototherapy on the massage area.

[0089] In some other possible embodiments, when the first sub-massage head 20a and the second sub-massage head 20b are brought close to each other to their minimum distance, the extended lines of the axes of the first sub-oscillating arm 32c and the second sub-oscillating arm 32d intersect, and the point of intersection is located on the side near the skin surface 10a. Simultaneously, when the first sub-massage head 20a and the second sub-massage head 20b are moved away from each other to their maximum distance, the extended lines of the axes of the first sub-oscillating arm 32c and the second sub-oscillating arm 32d intersect, and the point of intersection is located on the side away from the skin surface 10a.

[0090] By defining the relationship between the axes of the massage head swing arm 32, the light emitted by the phototherapy component 40 of the first sub-massage head 20a and the phototherapy component 40 of the second sub-massage head 20b can both converge and diverge. When converging, the phototherapy component 40 can concentrate the phototherapy on the massage area, and when diverging, the phototherapy component 40 can sweep across a larger area of ​​the massage area to achieve the maximum phototherapy range.

[0091] In some possible implementations, the two massage heads 201 closest to both ends of the movement housing 10 in the first direction X are respectively configured as a first end massage head 20c and a second end massage head 20d. The first end massage head 20c and the second end massage head 20d move closer to each other or further away from each other in the first direction X under the action of the power assembly 31 and the swing arm 32.

[0092] Optionally, in this embodiment, when the first end massage head 20c and the second end massage head 20d are brought close to each other to their minimum distance, they intersect the extension lines of the axes of the swing arms 32 to which they are respectively connected, and the intersection point is located on the side near the skin surface 10a. Simultaneously, when the first end massage head 20c and the second end massage head 20d are moved away from each other to their maximum distance, they intersect the extension lines of the axes of the swing arms 32 to which they are respectively connected, and the intersection point is located on the side away from the skin surface 10a.

[0093] See also Figure 3 and Figure 4 In order to enable the massage mechanism 20 to perform phototherapy over a larger area, in some possible embodiments, the phototherapy component 40 includes two components, which are respectively disposed on the first end massage head 20c and the second end massage head 20d.

[0094] Since the massage heads located near both ends of the housing 10 affect the massage range in the first direction X, by limiting the two end massage heads to swing relative to or close to each other in the first direction X under the action of the power component 31 and the swing arm 32, and by setting the phototherapy component 40 on the two end massage heads, the massage range can be maximized. When the two end massage heads move away from each other and reach the farthest distance, the light emitted by the phototherapy component 40 can diffuse outward to a greater extent. When the two end massage heads move close to each other and reach the minimum distance, the light emitted by the phototherapy component 40 can be concentrated to a greater extent, providing concentrated treatment to the massage area. In this way, the irradiation area of ​​the massage area by the light source of the two end massage heads can be maximized, achieving a better phototherapy effect.

[0095] It is worth noting that when the two massage heads 201 closest to the two ends of the mechanism housing 10 are configured to move closer to or further away from each other along the first direction X under the action of the power assembly 31 and the swing arm 32, since it is also necessary to satisfy that any two adjacent massage heads 201 move closer to or further away from each other in the first direction X, then no massage head 201 may be provided between the first end massage head 20c and the second end massage head 20d. That is, the massage mechanism 20 includes only two massage heads 201, or the number of massage heads 201 provided between the first end massage head 20c and the second end massage head 20d can be an even number such as two or four.

[0096] For example, when the number of massage heads 201 is four, the two first massage heads 21 mentioned above are also the first end massage head 20c and the second end massage head 20d. The four massage heads are spaced apart along the first direction X on the core housing 10, from one end of the core housing 10 to the other end in the first direction X. Figure 3 and Figure 4The massage heads (from left to right on the paper) are designated as the first, second, third, and fourth massage heads. The first and fourth massage heads are the two closest to the two ends of the housing 10, respectively, and are configured as the first end massage head 20c and the second end massage head 20d. When the first and second massage heads are at their furthest distance from each other, the second and third massage heads are at their furthest distance from each other, and the third and fourth massage heads are at their furthest distance from each other. The first and fourth massage heads (first end massage head 20c and second end massage head 20d) are at their furthest distance from each other. Since two phototherapy components 40 are respectively disposed on the first end massage head 20c and the second end massage head 20d, that is, phototherapy components 40 are respectively provided on the first and fourth massage heads. In one example, phototherapy components 40 are provided only on the first and fourth massage heads. In another example, the first and fourth massage heads are equipped with phototherapy components 40, and the second and third massage heads can also be equipped with phototherapy components 40, so that each massage head is equipped with a phototherapy component 40 to achieve a deeper phototherapy effect.

[0097] Combination Figure 3 and Figure 4 In some possible embodiments, when the first end massage head 20c and the second end massage head 20d are close to each other to the minimum distance, the angle of inclination of the axis of the swing arm 32 of the first end massage head 20c and the second end massage head 20d relative to the second direction Y is α1. When the first end massage head 20c and the second end massage head 20d are far apart from each other to the maximum distance, the angle of inclination of the axis of the swing arm 32 of the first end massage head 20c and the second end massage head 20d relative to the second direction Y is α2, where α1 > α2.

[0098] As the first end massage head 20c and the second end massage head 20d approach each other, they can gather and pinch the muscles of the massage area. Since phototherapy is mainly used to massage the inner area between the two massage heads, by setting a larger angle of inclination of the axis of the swing arm 32 when the two end massage heads are close to each other to their minimum distance, that is, the two end massage heads swing inward to a greater extent, which can provide a more concentrated kneading force and achieve a deeper massage effect. At the same time, the light emitted by the phototherapy component 40 that swings along with it can be more concentrated, and the area irradiated during the swing is also larger, thereby achieving a more comprehensive and deeper massage phototherapy effect. As the first end massage head 20c and the second end massage head 20d move away from each other, they can stretch the muscles of the massage area that are pinched. By setting a smaller angle of inclination of the axis of the swing arm 32 when the two end massage heads are far apart from each other, that is, the two end massage heads swing outward to a smaller extent, the reduced outward swing angle can avoid overstretching the skin, thereby achieving a more comfortable massage effect.

[0099] Especially when the massage mechanism 100 is used for waist massage, the two end massage heads can be located on the left and right sides of the waist. At the same time, a deeper massage can be achieved on the inner area between the two end massage heads, while a larger area of ​​light therapy can be implemented, thus achieving a more comprehensive and deeper massage and light therapy effect.

[0100] The second direction Y is configured to be perpendicular to the near-surface 10a. It can be understood that this second direction Y can be the thickness direction of the movement housing 10, perpendicular to the first direction X.

[0101] In some possible implementations, the angle range of α1 is 25° to 40°, and the angle range of α2 is 10° to 20°. Optionally, the angle range of α1 can be 25° to 35°, 25° to 30°, or 30° to 40°, for example, α1 can be 30°, 35°, or 40°. The angle range of α2 can be 10° to 17°, 10° to 15°, or 15° to 20°, for example, α2 can be 10°, 15°, or 20°.

[0102] If the inward tilt angle α1 is too small, it will not achieve an effective pinching effect on the massaged area and will also affect the irradiation range of the light emitted by the phototherapy component 40, thus failing to achieve an effective phototherapy effect. If the inward tilt angle α1 is too large, the end massage head may apply excessive kneading pressure to the pinched muscles, causing pain to the user due to over-pinching of the massaged area, and may also interfere with the mechanism housing 10. Therefore, by limiting the inward tilt angle α1 of the massage head to a reasonable range, the phototherapy irradiation range can be large enough to provide a larger area of ​​phototherapy while also providing a good kneading sensation.

[0103] If the outward tilt angle α2 is too small, the massage range of the massage head will be limited, affecting the massage area; if the outward tilt angle α2 is too large, it will overstretch the skin of the massage area, affecting the comfort of the massage. Therefore, by limiting the outward tilt angle α2 of the massage head within a reasonable range, the massage head can have a larger massage area without overstretching the massage area, thus improving the comfort of the massage.

[0104] It is worth noting that the first massage head 21, the second massage head 22, the first sub-massage head 20a, the second sub-massage head 20b, the first end massage head 20c, and the second end massage head 20d are all parts of a plurality of massage heads 201, that is, different names defined for different embodiments of massage heads 201.

[0105] Please refer to the following: Figures 5 to 8 In some possible embodiments, each rocker arm 32 has a ball joint portion 321 at its first end 32a, and a ball groove 101 is provided on the inner surface of the movement housing 10. The ball joint portion 321 is rotatably disposed in the ball groove 101. That is, the rocker arm 32 is connected to the movement housing 10 by the ball joint portion 321 and the ball groove 101 to achieve a movable connection with the movement housing 10.

[0106] By providing a ball bearing portion 321 at the first end 32a of the swing arm 32 and a ball groove 101 on the inner surface of the mechanism housing 10, the second end 32b of the swing arm 32 is movably connected to the mechanism housing 10 through the fit between the ball bearing and the ball groove 101. During the swinging process of the swing arm 32, the groove wall surface of the ball groove 101 serves as a support surface, providing support for the swing arm 32 and thus providing sufficient support force for the massage head connected to the swing arm 32, making the movement of the massage head more reliable. At the same time, by using the ball groove 101 on the inner surface of the mechanism housing 10 to accommodate the ball bearing portion 321 of the swing arm 32, a certain constraint can be provided on the swing fulcrum of the swing arm 32, making the swing arm 32 more stable during the swinging process around the fulcrum, further improving the reliability of the massage head movement.

[0107] Optionally, the ball shaft portion 321 can be a sphere or a hemisphere, and correspondingly, the ball groove 101 can be a sphere-shaped ball groove 101 or a hemisphere-shaped hemispherical groove 101, as long as it can satisfy the contact between the spherical structure of the rocker arm 32 and the movement housing 10.

[0108] Combination Figure 6 and Figure 9In some possible embodiments, the power assembly 31 includes a power component 311, a plurality of eccentric gears 312 and a plurality of connecting arms 313. The power component 311 is disposed on the movement housing 10. Each eccentric gear 312 is rotatably disposed on the movement housing 10 and is connected to the power component 311. Each eccentric gear 312 rotates around the second direction Y under the drive of the power component 311. An eccentric shaft 312a is provided on the end face of each eccentric gear 312. One end of a connecting arm 313 is connected to an eccentric shaft 312a and the other end of a connecting arm 313 is connected to a rocker arm 32.

[0109] The power assembly 31 includes a power component 311, multiple eccentric gears 312, and multiple connecting arms 313. The eccentric shaft 312a on the eccentric gear 312 is connected to one end of the connecting arm 313, and the other end of the connecting arm 313 is connected to the swing arm 32. When the power component 311 drives the eccentric gear 312 to rotate circumferentially, the eccentric shaft 312a rotates accordingly, thereby driving the connecting arm 313 to move. Under the drive of the connecting arm 313, the swing arm 32 swings around the ball shaft 321 as the fulcrum, thereby driving the massage head connected to the second end 32b of the swing arm 32 to move closer or further away from each other along the first direction X. The massage head can reciprocate around the rotation axis located in the middle of the massage head at both ends in the third direction Z, thereby enriching the massage effect of the massage head when kneading massage during the process of moving closer or further away. Furthermore, by using an eccentric gear 312 and an eccentric shaft 312a mounted thereon to connect with the connecting arm 313 to drive the swing arm 32, the rotational motion can be converted into the swinging motion of the swing arm 32, resulting in high transmission efficiency, a compact structure, and more stable power output.

[0110] Optionally, the power assembly 31 may also include multiple worm gears 314, which are then connected to the eccentric gear 312 for transmission. The power component 311 may include a motor 311a and a worm 311b connected to the motor 311a. The worm 311b can mesh with the worm gears 314, so that when the motor 311a drives the worm 311b to rotate, the worm 311b synchronously drives the worm gears 314 to rotate, which in turn drives the eccentric gear 312 to rotate. Thus, under the driving action of the eccentric shaft 312a and the connecting arm 313, any two adjacent massage heads 201 will swing closer or further apart along the first direction.

[0111] Specifically, the worm gear 314, the eccentric gear 312, and the connecting arm 313 together constitute a transmission assembly. This transmission assembly is connected between the power component 311 and the swing arm 32, and is used to transmit the power of the power component 311 to the swing arm 32, so that the swing arm 32 swings and drives the massage head to swing.

[0112] Of course, in other embodiments, the power component 311 may include multiple motors 311a, which can be used to directly drive the eccentric gear 312 to rotate, and can also drive the rocker arm 32 to swing.

[0113] The following will use multiple massage heads 201, including two first massage heads 21 and two second massage heads 22, as an example to introduce the movement process of the massage heads.

[0114] It is understood that the multiple massage heads 201 can be divided into two massage groups, each massage group including a first massage head 21 and a second massage head 22. Correspondingly, the transmission components can also include two groups. Each group of transmission components can include a worm gear 314, two eccentric gears 312 and two connecting arms 313. The power component 311 is disposed between the two transmission components, and the two sides of the worm 311b of the power component 311 can be meshed with the worm gear 314 respectively. Taking one massage unit as an example, the worm gear 314 meshes with one of the eccentric gears 312, which in turn meshes with another eccentric gear 312. Both eccentric gears 312 are equipped with eccentric shafts 312a. One end of the connecting arm 313 is connected to the eccentric shaft 312a, and the other end is connected to the rocker arm 32. The worm gear 314 is connected to the worm 311b, which can mesh with the worm gear 314. Therefore, when the motor 311a drives the worm 311b to rotate, the worm 311b synchronously drives the worm gear 314 to rotate, thus driving the... The eccentric gear 312 connected to it rotates, which drives the eccentric shaft 312a on it to rotate. Under the drive of the eccentric shaft 312a, the connecting arm 313 moves, which in turn drives the swing arm 32 to swing, thereby causing one of the massage heads 201 (first massage head 21) to swing. At the same time, since the two eccentric gears 312 are connected to each other, the other eccentric gear 312 rotates and drives the eccentric shaft 312a on it to rotate. Under the drive of the eccentric shaft 312a, the connecting arm 313 moves, which in turn drives the swing arm 32 to swing, thereby causing the other massage head 201 (second massage head 22) to swing.

[0115] Optionally, continue reading Figure 6 The movement housing 10 may include an upper housing 11, a lower housing 12, and a bracket 13 connecting the two. The worm gear 314 and the eccentric gear 312 are both rotatably mounted on the lower housing 12. The lower housing 12 provides effective support for the worm gear 314 and the two eccentric gears 312, ensuring smooth operation during transmission. The connecting arm 313 can be mounted on the bracket 13, which provides support for the connecting arm.

[0116] Among them, the two eccentric gears 312 are arranged side by side along the first direction X, so that the two eccentric gears 312 drive the swing arm 32 to swing in a consistent manner.

[0117] Continue reading Figures 6 to 8 as well as Figure 10 In some possible embodiments, a plurality of limiting grooves 102 extending along the second direction Y are provided on the skin surface 10a. The limiting grooves 102 are connected to the interior of the core housing 10 and extend along the first direction X. A swing rod 32 is movably inserted through a limiting groove 102. The limiting groove 102 is used to limit the position of the swing rod along the third direction Z so that the projection of the swing trajectory of a massage head on the skin surface 10a is a straight line parallel to the first direction X.

[0118] By providing a limiting groove 102 near the skin surface 10a, the swing arm 32 can be movably inserted through the limiting groove 102. The limiting groove 102 extends along the first direction X and restricts the swing arm 32's swing along the third direction Z within the limiting groove 102. This ensures that the swing arm 32 swings only in the first direction X, thereby causing the massage head to move only in the first direction X. This prevents the massage head from shifting position in the third direction Z, allowing the two massage heads to move closer or further apart along the first direction X for massage, achieving consistency in massage direction and effect, and improving massage accuracy. Furthermore, when the massage head moves to any position, the mechanism housing 10 can provide stable support to the massage head via the swing arm 32, maintaining the stability of the massage head's movement.

[0119] It should be noted that, as mentioned above, under the drive of the swing arm 32, any two adjacent massage heads can swing towards or away from each other along the first direction X. The swing arm 32 can swing in any way that allows the adjacent massage heads to move closer or further away on the side near the skin surface 10a. For example, the swing arm 32 can rotate 360° around the first end 32a as the fulcrum (the trajectory of the second end 32b of the swing arm 32 is projected as a circle on the near skin surface 10a), or the swing arm 32 can rotate 180° around the first end 32a as the fulcrum (the trajectory of the second end 32b of the swing arm 32 is projected as a semicircle on the near skin surface 10a), etc.

[0120] Furthermore, this application further limits the movement mode of the swing arm 32 by using a limiting groove 102 extending along the first direction X. The swing arm 32 can only swing along the first direction X to achieve a movement mode of moving closer or further apart from each other. At this time, the projection of the movement trajectory of the second end 32b of the swing arm 32 onto the skin surface 10a is a straight line along the first direction X. That is, the projection of the movement trajectory of each massage head onto the skin surface 10a is a straight line along the first direction X.

[0121] The third direction Z is configured to be perpendicular to the first direction X and the second direction Y. As mentioned above, the first direction X can be the length direction of the movement housing 10, the second direction Y can be the thickness direction of the movement housing 10, and therefore, the third direction Z can be the width direction of the movement housing 10.

[0122] As can be seen from the foregoing, the two massage heads closest to both ends of the housing 10 in the first direction X are respectively configured as the first end massage head 20c and the second end massage head 20d. Under the action of the power assembly 31 and the swing arm 32, the first end massage head 20c and the second end massage head 20d move closer to each other or further away from each other in the first direction X.

[0123] In some possible embodiments, both the first end massage head 20c and / or the second end massage head 20d are provided with phototherapy components 40. That is, the first end massage head 20c is provided with phototherapy components 40, or the second end massage head 20d is provided with phototherapy components 40, or both the first end massage head 20c and the second end massage head 20d are provided with phototherapy components 40.

[0124] Continue reading Figure 6 In some possible embodiments, the limiting groove 102 through which the swing rod 32 of the first end massage head 20c and / or the second end massage head 20d passes has a first groove sidewall 102a and a second groove sidewall 102b arranged opposite to each other along the first direction X. That is, the limiting groove 102 through which the swing rod 32, which is connected to the massage heads near both ends of the movement housing 10, passes has a first groove sidewall 102a and a second groove sidewall 102b arranged opposite to each other along the first direction X. In the first direction X, the first groove sidewall 102a is located inside the second groove sidewall 102b. The distance from the projection of the contact point between the ball joint 321 and the movement housing 10 on the near-skin surface 10a to the projection of the first groove sidewall 102a on the near-skin surface 10a is L1, and the distance from the projection of the contact point between the ball joint 321 and the movement housing 10 on the near-skin surface 10a to the projection of the second groove sidewall 102b on the near-skin surface 10a is L2, where L1 > L2.

[0125] By limiting the two end massage heads to swing relative to each other or close to each other along the first direction X under the action of the power component 31 and the swing arm 32, and by setting the phototherapy component 40 on the two end massage heads, the massage range can be maximized and the area of ​​light irradiated by the phototherapy component 40 can be expanded, thereby achieving a more comprehensive massage phototherapy effect. At the same time, by limiting the position of the two opposite groove sidewalls of the swing arm 32 relative to the limiting groove 102, the inward swing angle of the end massage heads is greater than the outward swing angle. During the entire swing of the end massage heads, the massage area can be pinched more deeply to achieve a deeper massage. Furthermore, the light emitted by the phototherapy component 40 that swings along with it can be more concentrated, and the irradiated area during the swing is also larger, thereby achieving a more comprehensive and deeper massage phototherapy effect.

[0126] It should be noted that, in the first direction X, the first groove sidewall 102a is located inside the second groove sidewall 102b. This inside refers to the inner region relative to the area where the first end massage head 20c and the second end massage head 20d are close to each other. If the first end massage head 20c and the second end massage head 20d are arranged alternately along the first direction X, then the sidewall closer to the massage part of the second end 32b is the first groove sidewall 102a among the two sidewalls of the limiting groove 102 corresponding to the first end massage head 20c, and the sidewall closer to the massage part of the first end 32a is the first groove sidewall 102a among the two sidewalls of the limiting groove 102 corresponding to the second end massage head 20d. When both the first end massage head 20c and the second end massage head 20d are provided with phototherapy components 40, then the two first groove sidewalls 102a of the limiting grooves 102 corresponding to them are arranged opposite each other along the first direction X, and both are located in the inner region where the two end massage heads are close to each other.

[0127] It is understandable that when the first end 32a of the swing arm 32 is provided with a ball joint portion 321, and is movably connected to the ball groove 101 provided on the inner surface of the movement housing 10, a limiting groove 102 can be provided on the movement housing 10 to achieve a movement form in which the swing arm 32 only swings in an arc along the first direction X (the projection of the movement trajectory of the second end 32b of the swing arm 32 onto the near-surface surface 10a is a straight line along the first direction X). Of course, in some possible embodiments, combined with Figure 7 The first end 32a is provided with a first shaft connection portion 322, and the inner surface of the movement housing 10 is provided with a second shaft connection portion 103. The axes of the first shaft connection portion 322 and the second shaft connection portion 103 extend along a third direction Z, and the first shaft connection portion 322 is rotatably connected to the second shaft connection portion 103. The third direction Z is configured to be parallel to the near-surface surface 10a and perpendicular to the first direction X. This third direction Z can also be the width direction of the movement housing 10.

[0128] In this embodiment, since the first end 32a of the swing arm 32 rotates about the third direction Z through the first shaft connection 322 and the second shaft connection 103 on the movement housing 10, the swing arm 32 can swing in an arc shape in a plane perpendicular to the near skin surface 10a and the first direction X. Similarly, the projection of the motion trajectory of the second end 32b of the swing arm 32 onto the near skin surface 10a is a straight line along the first direction X.

[0129] By providing a first shaft connection 322 at the second end 32b, which is rotatably connected to a second shaft connection 103 on the mechanism housing 10, and setting the axes of the first shaft connection 322 and the second shaft connection 103 along a third direction Z, the swing arm 32 can rotate around the third direction Z. Similarly, the swing arm 32 can swing back and forth in the first direction X, making its trajectory a straight line along the first direction X. Because of the shaft connection, the swing arm 32 can only rotate around the axis along the third direction Z, reducing the possibility of the swing arm 32 swaying in other directions, making the movement of the swing arm 32 more reliable, thereby improving the reliability of the massage head's movement.

[0130] See Figure 11 In some possible embodiments, the massage head equipped with the phototherapy component 40 includes a base 211 and a cover plate 212 connected to the base 211. The base 211 is connected to the second end 32b of the swing arm 32. The base 211 is provided with a mounting cavity 213. The phototherapy component 40 is disposed in the mounting cavity 213. The cover plate 212 covers the mounting cavity 213. The cover plate 212 has a light-transmitting area, through which the light emitted by the phototherapy component 40 is emitted.

[0131] The massage head includes a base 211 and a cover plate 212, and the mounting cavity 213 is provided on the base 211 to set the phototherapy component 40. This provides sufficient space for the phototherapy component 40. Furthermore, the use of the inwardly recessed mounting cavity 213 to set the phototherapy component 40 does not excessively increase the volume of the massage head, making the overall structure of the massage head more compact and more conducive to miniaturization design.

[0132] In some possible implementations, each massage head 201 has an elongated structure, and each phototherapy component 40 includes a plurality of light source components 41, which are spaced apart along the length of the massage head 201.

[0133] By setting the massage head 201 to a long strip shape and arranging the multiple light source components 41 of the phototherapy component 40 along the length of the massage head, the area swept by the light emitted by the phototherapy component 40 can be wider during massage, making it easier to perform large-area phototherapy on the massage area.

[0134] It should be noted that the phototherapy component 40 may also include a circuit board 42, on which the aforementioned light source component 41 can be disposed for electrical connection. Optionally, the light source component 41 may be an LED bead or a laser diode, or other structure capable of emitting light of different colors, thereby achieving a phototherapy effect. As mentioned above, the light source component 41 may emit infrared light, near-infrared light, or blue light, or other light capable of achieving a phototherapy effect.

[0135] Optionally, such as Figure 11 As shown, the base 211 includes a first part 211a and a second part 211b. The first part 211a is connected to the second part 211b to form a mounting cavity 213 for mounting a phototherapy component between the two. The phototherapy component 40 is connected to the first part 211a. The second part 211b is provided with multiple through holes, through which the light source component on the phototherapy component can extend out of the second part. That is, the second part 211b is connected between the cover plate 212 and the first part 211a, so that the light emitted by the light source component 41 is emitted through the light-transmitting area of ​​the cover plate.

[0136] In some possible implementations, each massage head extends parallel to the skin surface 10a along its length and is disposed in a direction perpendicular to the first direction X. That is, the extension direction of the massage head is perpendicular to the direction in which any two adjacent massage heads 201 move closer or further apart.

[0137] By extending the massage head along a direction perpendicular to the first direction X, that is, the length direction of the massage head is perpendicular to the direction of movement of the massage head, the elongated massage head can better gather the muscles as the two massage heads approach each other, and can gather a larger range of muscles, making the massage range wider. Furthermore, during the oscillation of the massage head, the area swept by the light emitted by the phototherapy component 40 on the massage head is further increased, resulting in a larger massage range and a larger area covered by the light.

[0138] In some possible implementations, the length of each massage head ranges from 8cm to 12cm. Alternatively, the length of each massage head can range from 8cm to 10cm, 8cm to 9cm, or 10cm to 12cm, for example, the length of each massage head can be 8cm, 9cm, 10cm, or 12cm.

[0139] If the massage head is too short, the massage area will be small, which is not conducive to all-round massage and will result in a small area of ​​light therapy coverage, failing to effectively achieve the light therapy effect. If the massage head is too long, it will not only increase the size of the massage head, which is not conducive to the miniaturization of the entire massage mechanism, but will also affect the structural strength of the massage head itself.

[0140] By appropriately setting the length range of the massage head, it can be matched to the massage area, especially the waist, which is better suited to the waist width, covering multiple acupoints and achieving a large-area massage. It also allows for a more reasonable distribution of the light source in the phototherapy component 40, improving the uniformity of phototherapy. Furthermore, it enables the overall miniaturization of the massage mechanism 100 and increases the structural strength of the massage head, thereby improving the reliability of the massage head's movement.

[0141] See Figure 12 This application also discloses a waist massager 200, including a waist belt 2a and a massage mechanism 100 as described in the above embodiments, wherein the massage mechanism 100 is disposed on the waist belt 2a.

[0142] In one example, a portion of the massage mechanism 100 is disposed inside the waist belt 2a, while another portion is disposed outside the waist belt 2a. Specifically, the mechanism housing 10 is disposed inside and connected to the waist belt 2a, while the massage mechanism 20 is disposed outside the waist belt 2a for direct contact with the waist for massage. In another example, the entire massage mechanism 100 is disposed inside the waist belt 2a, and the massage mechanism 20 can indirectly contact the waist for massage.

[0143] The waist belt 2a, which allows the entire waist massager 200 to be worn on the waist, is generally elongated in shape. The material of the waist belt 2a includes, but is not limited to, fabric and leather. For ease of wear, both ends of the waist belt 2a are equipped with interlocking fasteners such as Velcro, magnetic buckles, and clips to facilitate locking and unlocking during use.

[0144] Understandably, the belt 2a can be a structure made of only one material, or it can be a structure made of multiple materials, such as fabric on the side closer to the waist and leather on the side further away from the body.

[0145] Of course, in other embodiments, the belt 2a can also be in the form of having a flexible layer and a filling layer inside the flexible layer. The filling layer can be an elastic material such as sponge or memory foam, which would give the belt 2a greater elasticity and better wearing comfort.

[0146] Optionally, the belt 2a can be a belt 2a that only serves a wearing function, or it can be a belt 2a with built-in wiring. The wiring can be a power line or a signal line. The wiring connects the massage mechanism 100 to the power supply, or connects the massage mechanism 100 to the control unit, etc.

[0147] Furthermore, the massage mechanism 100 can be detachably connected to the waist belt 2a. The detachable connection can take various forms, including but not limited to buckle connections, magnetic connections, and screw connections. By separating the waist belt 2a from the massage mechanism 100, the waist belt 2a can be separated from the massage mechanism 100 and washed separately during prolonged use of the waist massager 200. This avoids the health risks associated with bacterial growth on the waist belt 2a during extended use, ensuring the waist belt 2a remains clean.

[0148] In some possible implementations, a plurality of massage heads 201 are spaced apart along the length of the waist belt 2a, and the length of the massage heads extends along the width of the waist belt 2a.

[0149] Because the waist belt 2a is a long strip worn around the waist, by arranging multiple massage heads at intervals along the length of the waist belt 2a, a larger placement space is provided for the massage heads. This allows the massage heads to massage in the width direction of the waist and ensures that the light therapy and massage cover the main areas of the waist. Furthermore, by extending the length of the massage heads along the width of the waist belt 2a, the massage heads can move and massage along the length of the waist belt 2a, making them more conform to the waist curve and allowing for a wider massage range in the width direction, thereby expanding the overall area of ​​waist massage.

[0150] The massage mechanism and waist massager disclosed in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the massage mechanism and waist massager of this application and their core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
