Referring to FIG. 1 to FIG. 7, a massage device according an embodiment of the present application is shown. In this embodiment, the massage device 100 includes a shell 20 and a stimulation assembly mounted in the shell 20.

As shown in FIG. 3 and FIG. 4, the shell 20, preferably, is a double-layer structure, and includes an outer shell 20a and an inner shell 20b being integrally fixed inside the outer shell 20a. The inner shell 20b may be made of hard materials, such as plastic, metal and etc., which has a relatively high strength and thus provides support for the stimulation modules 30, 40 mounted inside the shell 20. The outer shell 20a may be made of flexible materials, such as silicone, rubber and etc., for directly contacting a part of the human body which needs to be stimulated, so that the present massage device 100 in whole has high strength and comfortable use experience.

In a specific embodiment, firstly, the inner shell 20b is assembled with components to be installed inside the shell 20, such as the stimulation assembly and etc.; and then, the outer shell 20a is formed around the inner shell 20b through over-molding, achieving good sealing effect for the components inside the shell 20. The outer shell 20a is integral and play a waterproof and dustproof role, facilitating cleaning and storage of the massage device 100.

In this embodiment, the shell 20 includes a main portion 22, a first massage portion 24 and a plurality of second massage portions 26. The main portion 22 is configured as a double-layer structure, providing support for the stimulation assembly and etc. The second massage portions 26 extend integrally and outwardly from the outer shell 20a of the main portion 22, and the first massage portion 24 is surrounded by and connected to inner ends of the second massage portions 26 integrally. A chamber 28 is formed among the second massage portions 26 for accommodating a part of the human body (such as the breasts) that needs to be stimulated therein. Preferably, the chamber 28 has a size decreased gradually and inwardly. That is, the chamber 28 has the maximum size at its open side.

In this embodiment, the first massage portion 24 is dome-like, and the second massage portion 26 is sheet-like. In whole, the first and second massage portions 24, 26 are configured like a flower, wherein the first massage portion 24 is configured as a flower core, and the second massage portions 26 are configured as flowers petals. Outer ends of the second massage portions 26 extend slightly away from each other, and thus the chamber 28 is generally bowl-shaped, which can fit the shape of the breasts of the human body better. Specifically, a depth “d” of the chamber 28 may be 3-300 mm, and the diameter “D” of the chamber 28 at its open side may be 10-200 mm.

In this embodiment, the second massage portions 26 are set evenly along a circumferential direction, and symmetrical relative to the first massage portion 24. Specifically, the second massage portions 26 are spaced from each other in the circumferential direction, and a gap 29 is defined between each two neighboring second massage portions 26. Thus, the second massage portions 26 will not interfere with each other during operation. Accordingly, swinging amplitude of the second massage portions 26 may be greater and stimulation to the human body may be stronger. It should be understood that the second massage portions 26 may be set unsymmetrically, and/or, may be formed with different sizes or shapes.

In this embodiment, the first massage portion 24 of the shell 20 is configured as a vibration portion, and the second massage portions 26 of the shell 20 are configured as swinging portions. That is, the shell 20 is configured with two different massage portions for generating two different kinds of motions. Correspondingly, the stimulation assembly includes a first stimulation module 30 configured for driving the first massage portion 24 to vibrate and a second stimulation module 40 configured for driving the second massage portions 26 to swing relative to the first massage portion 24.

As shown in FIG. 3 and FIG. 4, the first stimulation module 30 includes at least one vibration motor, which is embedded in the first massage portion 24 of the shell 20 for generating high-frequency vibration to the part of the human body accommodated inside the chamber 28. When the present the massage device 100 is used to stimulate the breasts, the vibration motor 30 drives the first massage portion 24 to stimulate the nipples, obtaining a better stimulation effect.

As shown in FIG. 5 and FIG. 6, the second stimulation module 40 includes a gearbox 42, a swinging unit 44, and a transmission unit 46 connected between the gearbox 42 and the swinging unit 44.

Referring to FIG. 7, the gearbox 42 includes a rotary motor 421 and a reduction gear unit 423 connected to the rotary motor 421. The rotary motor 421 serves as a driving component of the second stimulation module 40 and has an output shaft 422 rotating at high-speed. The reduction gear unit 423 includes a gear housing 425 and a plurality of gears 427 arranged in the gear housing 425. The gears 427 mesh with each other, and a reduction ratio of the whole gearbox 42 can be determined according to the gear ratios between the meshed gears 427 of the reduction gear unit 423. In an embodiment, the reduction ratio of the gearbox 42 is not less than 4:1 and not more than 100:1.

The reduction gear unit 423 has an output shaft 429, wherein the output shaft 429 serves as an output shaft of the gearbox 42. Under the reduction effect of the reduction gear unit 423, a speed of the output shaft 429 does not exceed 1000 rpm.

The transmission unit 46 is configured for converting rotation of output shaft 429 of the gearbox 42 into reciprocating linear movement. In this embodiment, the transmission unit 46 includes an eccentric wheel 461 and a sliding member 462.

The eccentric wheel 461 is connected to the output shaft 429 at a central portion thereof. In this embodiment, the eccentric wheel 461 defines a central hole 463 for inserting of the output shaft 429 therein. The central hole 463 is non-circular shaped, such as D-shaped, and a cross section of the output shaft 429 has a shape matching with that of the central hole 463. After inserting of the output shaft 429 into the central hole 463, a relative rotation therebetween is limited for shape fitting, thereby the eccentric wheel 461 can rotate along with the output shaft 429 of the gearbox 42.

An eccentric rod 464 is set eccentrically on the eccentric wheel 461 and extends towards the sliding member 462. Generally, the eccentric rod 464 is parallel to the output shaft 429 of the gearbox 42. In this embodiment, as shown in FIG. 5, the eccentric rod 464 and the output shaft 429 both extends along X-direction. During rotation of the eccentric wheel 461 along with the output shaft 429, the eccentric rod 464 revolves round the output shaft 429 in YZ plane. In other words, under the driving of the gearbox 34, the eccentric rod 464 generates displacements in both Y-direction and Z-direction.

The sliding member 462 defines a sliding groove 465 therein, which is generally strip-shaped and elongated in a direction perpendicular to the eccentric rod 464, such as the Y-direction. The eccentric rod 464 engages into the sliding groove 465, and is fixed relative to the sliding member 462 in the Z-direction whilst is slidable relative to the sliding member 462 in the Y-direction. During revolving of the eccentric rod 464 round the output shaft 429, its displacement in the Y-direction makes it slide relative to the sliding member 462 along the sliding groove 465, while its displacement in the Z-direction drives the sliding member 462 to move along with it in the Z-direction.

By means of the cooperation of the eccentric rod 464 of the eccentric wheel 461 and the sliding groove 465 of the sliding member 462, rotation of the gearbox 42 is converted into reciprocating linear motion of the sliding member 462 in the Z-direction.

The swinging unit 44 includes multiple swinging bars 441 arranged around the sliding member 462. Each of the swinging bars 441 is rotatably connected to the shell 20, preferably the inner shell 20b, by a first pivot 442. In this embodiment, the swinging bar 441 is generally sheet-like and elongated in the Z-direction. One end of the swinging bar 441, preferably an end away from the first pivot 442, is configured as a swinging end 443 and extends into one of the second massage portions 26 of the shell 20; and, another end of the swinging bar 441, preferably an end adjacent to the first pivot 442, is configured as a connecting end 444 and connected to the sliding member 462.

The first pivots 442 extend perpendicular to the Z-direction, wherein some of the first pivots 442 extend along the X-direction, and some of the first pivots 442 extend along the Y-direction. When the sliding member 462 moves in the Z-direction, the swinging bars 441 are driven to swing about the first pivots 442, respectively. That is, the swinging bars 441 swing in the XZ plane or YZ-plane. The swinging ends 443 of all of the swinging bars 441 swing towards or away from each other synchronously, achieving an occlusion action to knead the part of the human body entering the chamber 28 and covered by the swinging bars 441.

Further, a sliding frame 48 is provided inside the shell 20 for rotatably connecting the swinging bars 441 to the sliding member 463. In this embodiment, the sliding frame 48 is generally constructed as a polygon structure with a number of lateral edges the same as the number of the swinging bars 441/second massage portions 26. The connecting end 444 of each swinging bar 441 is rotataly connected to a lateral edge of the sliding frame 48 by a second pivot 481. Each second pivot 481 is set to be generally parallel to a corresponding first pivot 442 for the same swinging bar 441.

The sliding frame 48 may be formed separately and then assembled to the sliding member 462, or, may be integrally formed with the sliding member 462 as one piece, as long as the sliding frame 48 can move together with the sliding member 462. In this embodiment, the second pivot 481 is integrally formed with the sliding frame 48 as one piece, and a U-shaped groove 445 is defined in the connecting end 444 of the swinging bar 441 for facilitating assembly of the second pivot 481 and the swinging bar 441. It should be understood that, in other embodiment, the second pivot 481 may be formed separately and then assembly to the sliding frame 48 and/or swinging bar 441.

In this embodiment, as shown in FIG. 5, the sliding frame 48 is generally square-shaped, and four swinging bars 441 are provided to connect four lateral edges of the sliding frame 48, respectively. Correspondingly, the shell 20 includes four second massage portions 26 arranged around the first massage portion 24 for accommodating the swinging ends 443 of the four swinging bars 441 therein, respectively. It should be noted that the number of the second massage portions and/or swinging bars are not limited to be four as the above embodiment.

FIG. 8 shows a second stimulation module 40a of a massage device according to an alternative embodiment. In this embodiment, the second stimulation module 40a includes three swinging bars 441 connected to the transmission unit 46 by a sliding frame 48a which is generally hexagonal-shaped. Preferably, the massage device may have 3-8 swinging bars 441, such as five or six swinging bars 441. Correspondingly, there may be 3-8 second massage portions 26. The sliding frame 48 may be configured with a number of lateral edges the same or larger than that of the swinging bars 441/second massage portions 26.

During operation, the sliding member 462 and the sliding frame 48 move together in the Z-direction under the driving of the gearbox 42, and in turn drives the swinging bars 441 to swing about the first pivots 442 relative to the shell 20, and swing about the second pivots 481 relative to the sliding frame 48 at the same time, thereby the swinging ends 443 and the second massage portions 26 swinging towards or away from the first massage portion 24 to knead the human body, which is similar to a pinch motion of the human hand, providing a more comfortable sexual stimulation, and thus the users are more likely to reach orgasm with the help of the present massage device 100.

In this embodiment, the first pivot 442 is adjacent to the connecting end 444 and away from the swinging end 443 of the swinging bar 441, so that the swinging end 443 of the swinging bar 441 which rotates about the first pivot 442 can get a greater swing amplitude even if a swinging angle of the swinging bar 441 rotating about the second pivot 481 is small. Accordingly, the second massage portions 26 driven by the swinging bars 441 can provide an enhanced stimulation to the human body.

Referring to FIG. 3 and FIG. 4 again, a control circuit board 60 is mounted in the shell 20 and electrically connected to the rotary motor 421 and vibration motor 30 for controlling their operation according to user's instructions, such as controlling the vibration frequency of the vibration motor 30, controlling the rotary speed of the rotary motor 42, and etc. Control buttons 62, such as mechanical buttons or touch buttons, may be provided on the outer shell 20a for input the user's instructions. Further, a battery 64, preferably a rechargeable battery, is arranged in the main portion 22 of the shell 20 and electrically connected to electric components, such as the rotary motor 421, the vibration motor 30, and etc., through the control circuit board 60 for supplying electric power.

During operation, the second stimulation module 40 may be started separately to achieve a stimulation effect to the human body, such as the breasts, through swinging of the second massage portions 26; or, the first stimulation module 30 may be started separately to achieve a stimulation effect to the human body through the high-frequency vibration of the first massage portion 24; or, the first and second stimulation modules 30, 40 may be started at the same time to provide a multi-stimulation effect to the human body. For enhance user comfort, the second massage portions 26 and the first massage portion 24 of the shell 20 are constructed as a soft single-layer structure, i.e., without the hard inner shell 24.

For the above massage device 100, the chamber 28 is formed among several second massage portions 26 to accommodate a part of the human body, such as the breasts, and the second massage portions 26 swing towards or away from the first stimulation module 30 to pinch the part of the human body inside the chamber 28, which is more suitable for women, particularly for stimulating the breasts of the women. It should be understood that stimulating the breasts may not enhance the sexual experience during sexual life, but also play a role in treating breast diseases in healthcare. In addition, such massage device may also be used for man, such as stimulating the glans penis.

As shown in FIG. 16, the gearbox 42c is arranged with the output shaft 429c thereof extending along the X-direction, while an output shaft 431c of the steering gear unit 43c extends along the Z-direction. In other embodiments, the output shaft 431c of the steering gear unit 43c may be inclined to the output shaft 429c of the gearbox 42c. In other embodiments, the rotary member 74c may be connected to the output shaft 429c of the gearbox 42c directly, thereby omitting the steering gear unit 43c.

The fixed member 72c is fixedly mounted in the shell 20c, a first sliding groove 721c which extends along the Z-direction is defined in the fixed member 72c. The rotary member 74c is rotatably mounted inside the shell 20c, a second sliding groove 741c which extends spirally in the circumferential direction is defined in the rotary member 74c. The sliding member 76c cooperates with the first sliding groove 721c and second sliding groove 741c simultaneously, converting the rotation of the rotary member 74c into reciprocating linear motion of the sliding member 76c in the Z-direction.

In this embodiment, a mounting seat 78c is provided inside the shell 20c, particularly inside an inner shell 201c, for accommodating the steering gear unit 43c, the fixed member 72c, the rotary member 74c, and the sliding member 76c therein.

As shown in FIG. 22, in this embodiment, the stimulation assembly includes a first stimulation module 30d, such as a vibration motor provided inside the first massage portion 24d of the shell 20d for driving the first massage portion 24d to vibrate; a second stimulation module 40d for driving the second massage portions 26d to swing towards or away from the first massage portion 24d; and a third stimulation module 50d for driving the first massage portion 24d to swing.

As shown in FIG. 23, the second stimulation module 40d includes a gearbox 42d, a swinging unit 44d, and a transmission unit 46d connected between the gearbox 42d and the swinging unit 44d for converting rotation of the gearbox 42d into reciprocating linear movement.

The transmission unit 46d includes a fixed member 72d defining a first sliding groove 721d therein, a rotary member 74d defining a second sliding groove 741d therein, and a sliding member 76d with a first sliding portion 761d being slidably engaged into the first sliding groove 721d and a second sliding portion 763d being slidably engaged into the second sliding groove 741d (refereeing to FIG. 21). The first sliding groove 721d of the fixed member 72d is elongated in the Z-direction, and the second sliding groove 741d of the rotary member 74d extends spirally in the circumferential direction.

In this embodiment, through holes 729d are defined at an end (such as a bottom end) of the fixed member 72d, and fixing members, such as screws, extend through the through holes 729d to fix the fixed member 72d in the shell 20d, such as fix to a gear housing 425d of the gearbox 42d. The rotary member 74d is configured as a rotary shaft, being rotatably mounted in the fixed member 72d and connected to an output shaft 429d of the gearbox 42d in a transmission way. The sliding member 76d is configured as a hollow sleeve, and mounted around the fixed member 72d. Two connecting rods 769d extend radially and outwardly from the sliding member 76d.

The swinging unit 44d includes two swinging bars 441d arranged at two opposite sides of the sliding member 76d, respectively. Each swinging bar 441d is rotatably connected to the shell 20d, particularly an inner shell 201d, by a first pivot 442d, wherein the first pivot 442d is parallel to the connecting rod 769d. An end of the swinging bar 441d away from the first pivot 442d is configured as a swinging end 443d and extends into one of the second massage portions 26d of the shell 20d; and, another end of the swinging bar 441d adjacent to the first pivot 442d is configured as a connecting end 444d for connecting the sliding member 76d.

In this embodiment, the connecting end 444d of each swinging bar 441d defines an elongated slot 445d therein. Each connecting rod 769d is movably and rotataly engaged into the elongated slot 445d of one corresponding swinging bar 441d, thereby the sliding member 76d can drive the connecting ends 444d of the swinging bars 441d to do reciprocating movement in the Z-direction synchronously, which in turn drives the swinging bars 441d to rotate about the corresponding first pivots 442d in opposite directions, respectively; and finally drives the swinging ends 443d and the second massage portions 26d to swing towards or away from the first massage portion 24d.

As shown in FIG. 23, the third stimulation module 50d includes a driving rod 56d, a swinging component 58d and a driving component such as a rotary motor, a gearbox and the like. The driving rod 56d is connected to the driving component in a transmission way, and is driven to rotate about a rotary axis which extends along the Z-direction. An eccentric rod 562d is set eccentrically on the driving rod 56d and extends towards the swinging component 58d. The swinging component 58d defines an elongated groove 581d for receiving the eccentric rod 562d, wherein the elongated groove 581d extends in a direction (such as the Y-direction) perpendicular to the rotary axis of the driving rod 56d.

The swinging component 58d is rotatably connected to the shell 20d by a third pivot 583d, wherein the third pivot 583d extends along the Y-direction, parallel to and spaced from the elongated groove 581d. During operation, the eccentric rod 562d is driven to revolve round the rotary axis of the driving rod 56d, its displacement in the Y-direction makes it slide relative to the swinging component 58d along the elongated groove 581d, while its displacement in the X-direction drives the swinging component 58d to move along with it in the X-direction, thereby making the swinging component 58d and the first massage portion 24d swing about the third pivot 583d in the XZ-plane.

As shown in FIG. 21, the first massage portion 24d defines a cavity 241d for receiving the swinging component 58d therein. Preferably, two support arms 203d extend from the inner shell 201d into the cavity 241d for support two ends of the third pivot 583d, respectively. Preferably, the swinging component 58d has an upper portion being embedded inside the first massage portion 24d, and a lower portion on which third pivot 583d and the elongated groove 581d are provided accommodated in the cavity 241d. The driving rod 56d extends into the cavity 241d, and the eccentric rod 562d is slidably inserted in the elongated groove 581d of the swinging component 58d.

Preferably, the swinging component 58d is made of hard materials, and the first stimulation module 30d is mounted in the swinging component 58d, and thus can swing together with the swinging component 58d and the first massage portion 24d. Therefore, the first massage portion 24d can not only stimulate the human body through high-frequency vibration caused by the first stimulation module 30d, but also knead the human body through swinging caused by the third stimulation module 50d, further enhancing the stimulation effect of the first massage portion 24d.

In this embodiment, the driving rod 56d is integrally formed on a top end of the rotary member 74d, and the gearbox 42d further serves as the driving component of the third stimulation module 50d. In other embodiments, the driving rod 56d may be formed separately and then connected to the gearbox 42d directly or indirectly. In other embodiments, another gearbox may be provided to drive the driving rod 56d to rotate, thereby the swinging motion of the first massage portion 24d can be controlled separately.
