Description

Technical Field

[0001] This invention relates to the field of massage equipment technology, and in particular to a double-headed cross-reciprocating oscillating massage device. Background Technology

[0002] Currently, in existing technologies, handheld massagers, due to the design requirements of easy operation and compact structure, typically use a single massage head or two massage heads set at opposite ends of a massage stick. The massage movements of the two massage heads are relatively independent. Existing massagers mainly rely on vibration to achieve the massage effect. Some massagers also use a single-head oscillation method for massage. However, these massage movements are relatively simple, and the massage effect and comfortable experience are not ideal, failing to meet users' strong demands for a better massage experience. Summary of the Invention

[0067] This application provides a dual-headed, cross-shaped, reciprocating massage device to solve the technical problem that existing massagers using single-headed massage movements have unsatisfactory massage effects and comfort experiences, failing to meet users' strong demands for a superior massage experience. By designing dual massage heads that cross-shaped and reciprocate to massage body parts, a dual-swinging motion massage is achieved, increasing the number of massages to enhance the massage effect and improve the comfort experience, thereby satisfying users' strong demands for a superior massage experience.

[0068] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0069] Please refer to the following: Figures 1 to 8 This embodiment provides a dual-headed reciprocating massage device, including a pivot 100, a first massage head 500, a second massage head 200, and a massage drive mechanism 300. The first end of the first massage head 500 is rotatably connected to the pivot 100; the first end of the second massage head 200 is rotatably connected to the pivot 100; the massage drive mechanism 300 is driven to the first end of the first massage head 500 and the first end of the second massage head 200, respectively, so that the massage drive mechanism 300 drives the second end of the first massage head 500 and the second end of the second massage head 200 to reciprocate around the central axis of the pivot 100 in a manner that brings them closer to or moves them further away from each other, thereby generating a massage action.

[0070] The dual-headed reciprocating massage device is a handheld massager suitable for massaging certain parts of the body. Certain massage components can be adapted to be installed and fixed on the heads of the first massage head 500 and the second massage head 200 according to the specific parts of the body being massaged, or the heads of the first massage head 500 and the second massage head 200 can be designed with a specific massage shape structure.

[0071] It can be seen that, as Figure 6 As shown, the dual-headed reciprocating massage device of this embodiment generates a massage action by driving the second ends of the first massage head 500 and the second massage head 200 to reciprocate around the central axis of the pivot 100 in a manner that moves closer or further apart from each other. The first massage head 500 and the second massage head 200 reciprocate back and forth to massage the body parts, realizing bidirectional swing massage. The swing speed is increased and the number of massages is increased, thereby enhancing the massage effect and improving the comfort of the massage experience to meet the user's strong demand for a good massage experience.

[0072] In this embodiment, as Figures 1 to 4As shown, the second end of the first massage head 500 is provided with a first flexible massage head 510, and the second end of the second massage head 200 is provided with a second flexible massage head 210. The flexible massage heads are more gentle and skin-friendly, making the massage of body parts more comfortable and avoiding skin abrasion. The massage heads can be made of silicone or rubber materials, and other flexible materials can also be used. The first massage head 500 and the second massage head 200 are arranged in a mirror symmetrical manner, and the shape and structure of the first flexible massage head 510 and the second flexible massage head 210 can be adaptively designed according to the specific parts of the body being massaged.

[0073] Among them, such as Figure 1 and Figure 4 As shown, the dual-head reciprocating oscillating massage device of this embodiment has a front cover 400, which is generally cylindrical. The front face of the front cover 400 has a pair of through holes 410, which are waist-shaped or elliptical. The pair of through holes 410 extend on the front face of the front cover 400 along a direction perpendicular to the central axis of the pivot 100. The first massage head 500 and the second massage head 200 are respectively inserted into the pair of through holes 410 to reserve space for the reciprocating oscillating movement of the first massage head 500 and the second massage head 200, so that when the first massage head 500 and the second massage head 200 reciprocate around the central axis of the pivot 100, they also reciprocate along the extension direction of the through holes 410.

[0074] The lower end of the first flexible massage head 510 and the lower end of the second flexible massage head 210 are connected as an integral structure through a flexible annular end face 240. Furthermore, the second end of the first massage head 500 and the second end of the second massage head 200 are respectively inserted into the first flexible massage head 510 and the second flexible massage head 210. The flexible annular end face 240 is installed and fixed on the front end face of the front end cover 400 to achieve a sealing, waterproof and moisture-proof effect.

[0075] Specifically, such as Figure 1 and Figure 4 As shown, the first flexible massage head 510 has a built-in first vibration motor 2520, and the second flexible massage head 210 has a built-in second vibration motor 220.

[0076] The second end of the first massage head 500 and the second end of the second massage head 200 both extend axially to form a receiving groove, which is a cylindrical groove. The first vibration motor 2520 and the second vibration motor 220 are both cylindrical. The lower ends of the first vibration motor 2520 and the second vibration motor 220 are respectively housed in the receiving grooves of the first massage head 500 and the second massage head 200. The upper ends of the first vibration motor 2520 and the second vibration motor 220 are respectively housed in the first flexible massage head 510 and the second flexible massage head 210. When the first massage head 500 and the second massage head 200 cross and reciprocate to massage the body parts, the massage effect is more intense when combined with the vibration massage of the first vibration motor 2520 and the second vibration motor 220.

[0077] In this embodiment, as Figures 1 to 6 As shown, the massage drive mechanism 300 includes: a rotating wheel 320, a drive unit 310, a first conversion unit 340, and a second conversion unit 330. The rotation axis of the rotating wheel 320 is configured to be perpendicular to the central axis of the pivot 100. The rotating wheel 320 has a first cam connection and a second cam connection. The drive unit 310 drives the rotating wheel 320 to rotate. The rotational motion of the rotating wheel 320 is converted into a reciprocating oscillating motion of the first massage head 500 around the central axis of the pivot 100 by the first conversion unit 340 cooperating with the first cam connection. The rotational motion of the rotating wheel 320 is converted into a reciprocating oscillating motion of the second massage head 200 around the central axis of the pivot 100 by the second conversion unit 330 cooperating with the second cam connection. The second massage head 200 and the first massage head 500 perform reciprocating oscillating massage actions in a manner that brings them closer to each other or moves them further away from each other.

[0078] Among them, such as Figure 6 As shown, the rotating wheel 320 is driven to rotate by the drive unit 310, and the rotational force of the rotating wheel 320 is transmitted to the first conversion unit 340 and the second conversion unit 330 through the first cam connection and the second cam connection of the rotating wheel 320, respectively. This causes the first conversion unit 340 and the second conversion unit 330 to push and pull the first end of the first massage head 500 and the first end of the second massage head 200, thereby causing the first massage head 500 and the second massage head 200 to reciprocate around the central axis of the pivot 100 in a manner that moves closer to or further away from each other, thus generating a massage action.

[0079] Specifically, such as Figures 1 to 6 As shown, the first cam connection has: a first boss wheel 321, which is stacked on the rotating wheel 320 in an eccentric state relative to the rotation axis of the rotating wheel 320, and a first cam surface is formed on the outer peripheral surface of the first boss wheel 321;

[0080] The second cam connection has a second boss wheel 322, which is eccentrically stacked on the first boss wheel 321 relative to the rotation axis of the rotating wheel 320, and a second cam surface is formed on the outer peripheral surface of the second boss wheel 322.

[0081] The first conversion part 340 includes a first sliding part 341 and a first conversion connection part 370. The first sliding part 341 has a first annular hole 342 and is movably engaged with the first cam surface of the first boss wheel 321 through the first annular hole 342. The first conversion connection part 370 is connected between the first sliding part 341 and the first end of the first massage head 500 so as to convert the movement of the first sliding part 341 into the reciprocating oscillating movement of the first massage head 500 around the central axis of the pivot 100 through the first conversion connection part 370.

[0082] The second conversion part 330 includes a second sliding part 331, a second conversion connection part 360, and a guide structure 350. The second sliding part 331 has a second annular hole 332, and the second sliding part 331 is movably engaged with the second cam surface of the second boss wheel 322 through the second annular hole 332. The second conversion connection part 360 is connected between the second sliding part 331 and the first end of the second massage head 200, so as to convert the movement of the second sliding part 331 into the reciprocating oscillating movement of the second massage head 200 around the central axis of the pivot 100 through the second conversion connection part 360. When the rotating wheel 320 is rotating, the guide structure 350 guides the first sliding part 341 and the second sliding part 331 to move along the movement path perpendicular to the central axis of the pivot 100, and at the same time, the movement directions of the first sliding part 341 and the second sliding part 331 are opposite.

[0083] Among them, such as Figure 4 and Figure 6As shown, the shapes of the first annular hole 342 and the second annular hole 332 are both approximately elliptical or waist-shaped. When the driving part 310 drives the rotating wheel 320 to rotate, the first boss wheel 321 and the second boss wheel 322 above the rotating wheel 320 rotate together with the rotating wheel 320. The first cam surface of the first boss wheel 321 rolls into contact with the inner wall of the first annular hole 342 of the first sliding part 341, and the second cam surface of the second boss wheel 322 rolls into contact with the inner wall of the second annular hole 332 of the second sliding part 331. Thus, the rotational force of the first boss wheel 321 and the rotational force of the second boss wheel 322 are respectively transmitted to the first sliding part 341 and the second sliding part 331. Under the guidance of the guide structure 350, the rotational force of the first boss wheel 321 and the second boss wheel 322 is transferred to the first sliding part 341 and the second sliding part 331. The first sliding part 341 and the second sliding part 331 move along a movement path perpendicular to the central axis of the pivot 100. Since the first boss wheel 321 and the second boss wheel 322 are staggered and stacked, the first sliding part 341 and the second sliding part 331 move in opposite directions at the same time. Under the action of the first conversion part 340 and the second conversion part 330, the movement of the first sliding part 341 and the second sliding part 331 is converted into the first massage head 500 and the second massage head 200 reciprocating around the central axis of the pivot 100 in a way that they move closer to each other or further away from each other, thereby realizing that the first massage head 500 and the second massage head 200 cross and reciprocate to massage the body parts.

[0084] like Figures 4 to 6 As shown, in this embodiment, the first boss wheel 321 of the rotating wheel 320 serves as the first cam connection point. The first boss wheel 321 engages with the first annular hole 342 of the first sliding part 341 to convert the rotational motion of the rotating wheel 320 and the first boss wheel 321 into the movement motion of the first sliding part 341. The second boss wheel 322 of the rotating wheel 320 serves as the second cam connection point. The second boss wheel 322 engages with the second annular hole 332 of the second sliding part 331 to convert the rotational motion of the rotating wheel 320 and the second boss wheel 322 into the movement motion of the second sliding part 331. It can be understood that the operating structure of the first cam connection point of the rotating wheel 320 engaging with the first sliding part 341 and the operating structure of the second cam connection point engaging with the second sliding part 331 can be modified by corresponding replacement of the motion mechanism and structural adjustment. Without creative effort, any replacement of the motion mechanism and structural adjustment that achieves the same motion function is within the protection scope of this invention.

[0085] In addition, such as Figures 4 to 6As shown, in this embodiment, the double cams above the rotating wheel 320 are respectively linked with the first sliding part 341 and the second sliding part 331 of the yoke type, so that a single drive part 310 can drive two massage heads to perform reciprocating oscillating massage movements in a way that moves closer or further apart. That is, a single drive achieves double oscillating motion, which makes the structure simpler and more compact, the drive transmission method more stable and reliable, the overall weight of the massage device is smaller, it is easier to use, easier to assemble, and lower in cost. Specifically, the drive part 310 can be a rotary motor, and the output shaft 311 of the drive part 310 is flat. The bottom of the rotating wheel 320 is provided with a prism-shaped mounting hole. The flat drive part 310 output shaft 311 is installed and engaged with the prism-shaped mounting hole of the rotating wheel 320 to play a circumferential positioning role, so that the drive part 310 can drive the rotating wheel 320 to rotate more stably.

[0086] In one possible implementation, such as Figures 1 to 6 As shown, the first conversion connection part 370 includes: a first shaft 344 and a first swing arm slot 530. The first shaft 344 is disposed on the left side of the first sliding part 341, and the central axis of the first shaft 344 extends in a direction parallel to the central axis of the pivot 100. The first swing arm slot 530 is disposed at the first end of the first massage head 500, and the first swing arm slot 530 extends downward along the longitudinal axis of the first massage head 500. The first swing arm slot 530 is movably engaged on the first shaft 344.

[0087] The second conversion connection part 360 includes a second shaft 334 and a second swing arm slot 230. The second shaft 334 is disposed on the right side of the second sliding part 331, and the central axis of the second shaft 334 extends in a direction parallel to the central axis of the pivot 100. The second swing arm slot 230 is disposed at the first end of the second massage head 200, and the second swing arm slot 230 extends downward along the longitudinal axis of the second massage head 200. The second swing arm slot 230 is movably engaged on the second shaft 334.

[0088] Among them, such as Figures 4 to 6As shown, when the drive unit 310 drives the rotating wheel 320 to rotate, the first boss wheel 321 and the second boss wheel 322 above the rotating wheel 320 cooperate with the first sliding part 341 and the second sliding part 331 respectively, so that the first sliding part 341 and the second sliding part 331 move along a movement path perpendicular to the central axis of the pivot 100 under the guidance of the guide structure 350. At the same time, the first sliding part 341 and the second sliding part 331 move in opposite directions, thereby causing the first shaft 344 on the left side of the first sliding part 341 to cooperate with the first swing arm slot 530 at the first end of the first massage head 500 to push and pull the first massage head 500 to reciprocate around the central axis of the pivot 100. The second shaft 334 on the right side of the second sliding part 331 cooperates with the second swing arm slot at the first end of the second massage head 200. The second massage head 200, in conjunction with the first massage head 500, reciprocates around the central axis of the pivot 100. At the same time, the first massage head 500 and the second massage head 200 swing in opposite directions. During the swinging process of the first massage head 500 and the second massage head 200, the first swing arm slot 530 and the second swing arm slot 230 rotate around the first shaft 344 and the second shaft 334, respectively. At the same time, the first shaft 344 and the second shaft 334 also slide along the extension direction of the first swing arm slot 530 and the second swing arm slot 230, respectively. The design structure of the first swing arm slot 530 and the second swing arm slot 230 provides an activity gap for the sliding of the first shaft 344 and the second shaft 334. The structure is simpler and more compact, the motion transmission method is more stable and reliable, the assembly is more convenient and quick, and the cost is lower.

[0089] Specifically, such as Figures 4 to 6 As shown, the first swing arm slot 530 and the second swing arm slot 230 are roughly fork-shaped. The first swing arm slot 530 is located on the left side of the first end of the first massage head 500, and the second swing arm slot 230 is located on the right side of the first end of the second massage head 200. The plane on which the plates of the first swing arm slot 530 and the second swing arm slot 230 are located is parallel, and this plane is perpendicular to the central axis of the pivot 100. In this way, the distance between the first swing arm slot 530 and the second swing arm slot 230 is larger. Under the premise of limited internal space of the massage device, sufficient movement space is provided for the first sliding part 341 and the second sliding part 331 to drive the first swing arm slot 530 and the second swing arm slot 230 to swing back and forth, so as to avoid malfunctions caused by interference contact during movement.

[0090] The first shaft 344 has a first flange 345 at one end near the first sliding part 341, and the second shaft 334 has a second flange 335 at one end near the second sliding part 331, so that the first swing arm slot 530 and the second swing arm slot 230 are axially positioned by the first flange 345 and the second flange 335 respectively.

[0091] In this embodiment, as Figures 3 to 4 As shown, the guide structure 350 includes: a fixed base 351, a first slider 343, and a second slider 333. The fixed base 351 extends along a direction perpendicular to the central axis of the pivot 100 and forms a guide groove 3513. The first slider 343 is disposed at the end of the first sliding portion 341 and is slidably mounted in the guide groove 3513 so as to guide the first sliding portion 341 to move along a movement path perpendicular to the central axis of the pivot 100 by sliding the first slider 343 along the extension direction of the guide groove 3513. The second slider 333 is disposed at the end of the second sliding portion 331 and is slidably mounted in the guide groove 3513 so as to guide the second sliding portion 331 to move along a movement path perpendicular to the central axis of the pivot 100 by sliding the second slider 333 along the extension direction of the guide groove 3513.

[0092] Specifically, such as Figures 3 to 4 As shown, the fixed base 351 is roughly cylindrical cup-shaped, and the upper and lower parts of the fixed base 351 are a large cylindrical sleeve 3512 and a small cylindrical sleeve 3511, respectively. The small cylindrical sleeve 3511 is fitted onto the upper end of the drive part 310. The large cylindrical sleeve 3512 is used to accommodate and install the pivot 100, the rotating wheel 320, the first conversion part 340, and the second conversion part 330. Partial guide grooves 3513 are formed on the inner walls of the cylinders at both the front and rear ends of the fixed base 351. The guide grooves 3513 guide the first slider 343 and the second slider 333 to move along a movement path perpendicular to the central axis of the pivot 100. The guide grooves 3513 are rectangular grooves. The first slider 343 and the second slider 333 are both strip-shaped plates. The first sliding part 341 and the second sliding part 331 are respectively supported on the guide grooves 3513 of the fixed base 351 through the first slider 343 and the second slider 333 to provide support and guidance.

[0093] In another possible implementation, such as Figures 7 to 8 As shown, the first conversion connection part 370 includes: a first swing arm end 550 and a first connecting rod 371. The first swing arm end 550 is disposed at the first end of the first massage head 500 and extends downward along the longitudinal axis of the first massage head 500. The first end of the first connecting rod 371 is pivotally connected to the end of the first slider 343 through a first pivot shaft 373, and the second end of the first connecting rod 371 is pivotally connected to the first swing arm end 550 through a second pivot shaft 372. The central axis of the first pivot shaft 373 and the central axis of the second pivot shaft 372 are both parallel to the central axis of the pivot 100.

[0094] like Figures 7 to 8As shown, the second conversion connection 360 includes a second swing arm end 250 and a second connecting rod 361. The second swing arm end 250 is disposed at the first end of the second massage head 200 and extends downward along the longitudinal axis of the second massage head 200. The first end of the second connecting rod 361 is pivotally connected to the end of the second slider 333 through a third pivot shaft 363, and the second end of the second connecting rod 361 is pivotally connected to the second swing arm end 250 through a fourth pivot shaft 362. The central axis of the third pivot shaft 363 and the central axis of the fourth pivot shaft 362 are both parallel to the central axis of the pivot 100.

[0095] Among them, such as Figure 4 , Figure 7 and Figure 8 As shown, when the drive unit 310 drives the rotating wheel 320 to rotate, the first boss wheel 321 and the second boss wheel 322 above the rotating wheel 320 cooperate with the first sliding part 341 and the second sliding part 331 respectively, so that the first sliding part 341 and the second sliding part 331 move along a movement path perpendicular to the central axis of the pivot 100 under the guidance of the guide structure 350. At the same time, the first sliding part 341 and the second sliding part 331 move in opposite directions, thereby causing the first slider 343 of the first sliding part 341 to drive the first connecting rod 371 to push and pull the first swing arm end 550 together with the first massage head 500 to reciprocate around the central axis of the pivot 100. The second slider 333 of the second sliding part 331 drives the second connecting rod The second swing arm end 250, along with the second massage head 200, reciprocates around the central axis of the pivot 100. At the same time, the swing directions of the first massage head 500 and the second massage head 200 are opposite. During the swing of the first massage head 500 and the second massage head 200, the first connecting rod 371 pushes and pulls the first swing arm end 550 relative to the first swing arm end 550, and the second connecting rod 361 pushes and pulls the second swing arm end 250 relative to the second swing arm end 250, so as to achieve the purpose of realizing double swing motion with single drive. The structure is simple and compact. Compared with the above-mentioned implementation, the implementation of the first conversion connection part 370 and the second conversion connection part 360 is relatively complex in structure, with additional parts such as the first connecting rod 371 and the second connecting rod 361.

[0096] Specifically, such as Figures 7 to 8As shown, the first link 371 extends at intervals by bending around the outer peripheral surface of the first sliding part 341, and the second link 361 extends at intervals by bending around the outer peripheral surface of the second sliding part 331. The first pivot shaft 373 and the third pivot shaft 363 are located at the two ends of the first sliding part 341, respectively. The first link 371 and the second link 361 are designed to be approximately centrally symmetrical, so that the first link 371 and the second link 361 have sufficient movement space when pushing and pulling the first swing arm end 550 and the second swing arm end 250, respectively, to avoid malfunctions caused by interference contact during movement, and the drive transmission structure is more stable and reliable.

[0097] In this embodiment, as Figures 3 to 4 As shown, support seats 3514 are provided on both the left and right sides of the fixed base 351, and the two ends of the pivot 100 are respectively placed on the two support seats 3514. The first massage head 500 and the second massage head 200 are rotatably connected to the pivot 100 along the central axis of the pivot 100. In addition, a cylindrical tube 540 protrudes between the first massage head 500 and the second massage head 200, and a spacer ring is provided between the cylindrical tube 540 of the first massage head 500 and the cylindrical tube 540 of the second massage head 200, so that the first massage head 500 and the second massage head 200 are rotatably connected to the pivot 100 through the cylindrical tube 540, so that the first massage head 500 and the second massage head 200 are more stable and reliable when they reciprocate around the pivot 100.

[0098] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0099] The dual-headed reciprocating massage device of the present invention generates a massage action by driving the second ends of the first massage head 500 and the second massage head 200 to reciprocate around the central axis of the pivot 100 in a manner that moves closer or further apart from each other. The first massage head 500 and the second massage head 200 reciprocate back and forth to massage body parts, realizing bidirectional reciprocating massage. The speed of reciprocating is increased and the number of massages is increased, thereby enhancing the massage effect and improving the comfort of the massage experience, so as to meet the user's strong demand for a good massage experience.
