The terms used in the description of this application are intended to explain specific embodiments only and are not intended to limit this application.Referring to FIGS. 1 to 7, a massage apparatus according to an embodiment of the present application is illustrated. In this embodiment, massage device 100 includes a housing 20 and a stimulation arrangement disposed in housing 20.As shown in FIGS. 3 and 4, the housing 20 is preferably a double-layered structure including an outer housing 20 aand an inner housing 20 bintegrally fixed in the outer housing 20 a. The inner housing 20 bmay be made of a hard material, such as plastic, metal, etc., that has high strength and thus provides support for the stimulation modules 30, 40 mounted in the housing 20. The outer housing 20a may be made of a flexible material such as silicone, rubber, etc. which is directly in contact with a part of the human body to be stimulated, so that the present massage device 100 as a whole provides high strength and a comfortable use experience.In a specific embodiment, the outer housing 20a is overmoulded around the inner housing 20b after the inner housing 20b is assembled with the components to be mounted in the housing 20, such as the stimulation assembly and the like, to achieve good sealing of the components within the housing 20. The outer housing 20 ais formed integrally and plays a role for water seal and dust seal, which promotes maintenance and storage of the massage device 100.In this embodiment, the housing 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 dual layer structure to provide support for the stimulation assembly and the like. The second massage portions 26 integrally extend outward from the outer housing 20 aof the main portion 22. The first massage portion 24 is surrounded by and integrally connected to the inner ends of the second massage portions 26. A chamber 28 is formed between the second massage portions 26 for accommodating a part of the human body (such as the chest) to be stimulated. Preferably, the chamber 28 has a size that gradually decreases inwardly. That is, the chamber 28 has the maximum dimension at its top.In this embodiment, the first massage portion 24 is dome-shaped and the second massage portion 26 is plate-shaped. The first massage portion and the second massage portions 24, 26 together are configured in the form of a flower, wherein the first massage portion 24 is configured as the center of the flower and the second massage portions 26 are configured as petal. Outer ends of the second massage portions 26 extend slightly away from each other, and thus the chamber 28 is formed in a substantially cup shape to be adaptable to the shape of the human body's chest. In particular, the depth d of the chamber 28 can be 3-300 mm and the diameter D of the chamber 28 on its open side can be 10-200 mm.In this embodiment, the second massage portions 26 are evenly distributed in a circumferential direction and arranged symmetrically with respect to the first massage portion 24. Specifically, the second massage portions 26 are spaced apart from each other in the circumferential direction, and a gap 29 is formed between each two adjacent second massage portions 26. Thus, the second massage sections 26 do not interfere with each other during operation. Therefore, the swing amplitude of the second massage portions 26 can be increased and the stimulation of the human body can be enhanced. It is to be understood that the second massage sections 26 can also be arranged asymmetrically and / or can be formed in different sizes or shapes.In this embodiment, the first massage portion 24 of the housing 20 is configured as a vibrating portion, and the second massage portions 26 of the housing 20 are configured as vibrating portions. That is, the housing 20 is configured with two different types of massage portions for generating two different types of movements. Accordingly, the stimulation assembly includes a first stimulation module 30 configured to vibrate the first massage portion 24 and a second stimulation module 40 configured to vibrate the second massage portions 26 relative to the first massage portion 24.As shown in FIGS. 3 and 4, the first stimulation module 30 includes at least one vibration motor installed in the first massage portion 24 of the housing 20 to generate high-frequency vibration at the part of the human body accommodated in the chamber 28. When the present massage device 100 is used for stimulating the chest, the vibration motor 30 drives the first massage portion 24 to stimulate the nipple so that a better stimulating effect is obtained.As shown in FIGS. 5 and 6, the second stimulation module 40 includes a gear 42, a pivoting unit 44, and a transmission unit 46 connected between the gear 42 and the pivoting unit 44.Referring to FIG. 7, the transmission 42 includes a rotation motor 421 and a reduction gear unit 423 connected to the rotation motor 421. The rotation motor 421 serves as a driving component of the second stimulation module 40 and has an output shaft 422 that rotates at a high speed. The reduction gear unit 423 includes a gear housing 425 and a plurality of gears 427 disposed in the gear housing 425. The gears 427 are meshed with each other, and the reduction ratio of the entire transmission 42 can be determined according to the ratio between the meshed gears 427 of the reduction gear unit 423. In one embodiment, the reduction ratio of the transmission 42 is not less than 4:1 and not more than 100:1.The reduction gear unit 423 has an output shaft 429. At this time, the output shaft 429 serves as the output shaft of the transmission 42. By the reduction of the reduction gear unit 423, the rotation speed of the output shaft 429 does not exceed 1000 rpm.The transmission unit 46 is configured to convert the rotation of the output shaft 429 of the transmission 42 into a linear reciprocating motion. In this embodiment, the transmission unit 46 includes an eccentric disk 461 and a sliding member 462.The eccentric disk 461 is connected to the output shaft 429 at a central portion thereof. In this embodiment, a central hole 463 for inserting the output shaft 429 is defined in the eccentric disk 461. The central hole 463 is formed non-circular, such as in a D-shape, and the cross section of the output shaft 429 has a shape matching the shape of the central hole 463. After the output shaft 429 is inserted into the central hole 463, the relative rotation therebetween is limited by positive locking, so that the eccentric disk 461 can rotate with the output shaft 429 of the transmission 42.An eccentric rod 464 is eccentrically attached to the eccentric disk 461 and extends to the slide member 462. Substantially, the eccentric rod 464 is parallel to the output shaft 429 of the transmission 42. in this embodiment, the eccentric rod 464 and the output shaft 429 extend in the X direction as shown in FIG. 5. During the co-rotation of the eccentric disk 461 with the output shaft 429, the eccentric rod 464 rotates about the output shaft 429 in the YZ plane. In other words, the eccentric rod 464 causes displacements in the Y direction and the Z direction under driving of the transmission 34.In the slide member 462, a slide groove 465 is defined which is formed substantially in a strip shape and elongated in a direction perpendicular to the eccentric rod 464 as in the Y direction. The eccentric rod 464 is engaged with the slide groove 465 and is fixed relative to the slide member 462 in the Z direction and simultaneously slidable relative to the slide member 462 in the Y direction. During the revolution of the eccentric rod 464 about the output shaft 429, its displacement in the Y direction results in its sliding relative to the sliding member 462 along the sliding groove 465, and its displacement in the Z direction drives the sliding member 462 in movement therewith in the Z direction.By the cooperation of the eccentric rod 464 of the eccentric disk 461 and the slide groove 465 of the slide member 462, the rotation of the gear 42 is converted into a linear reciprocating motion of the slide member 462 in the Z direction.The pivot unit 44 includes a plurality of pivot rods 441 disposed about the slide member 462. Each of the pivot rods 441 is rotatably connected to the housing 20, preferably to the inner housing 20b, by a first pivot 442. In this embodiment, the pivot rod 441 is substantially plate-shaped and elongated in the Z direction. One end, preferably the end remote from the first pivot pin 442, of the pivot rod 441 is configured as a pivot end 443 and extends into one of the second massage portions 26 of the housing 20.The first trunnions 442 extend perpendicular to the Z direction, some of the first trunnions 442 extend in the X direction and some of the first trunnions 442 extend in the Y direction. When the slide member 462 moves in the Z direction, the pivot rods 441 are vibrated about the respective first trunnions 442. That is, the pivot rods 441 swing in the XZ plane and the YZ plane, respectively. The pivotal ends 443 of all the pivotal rods 441 swing synchronously toward or away from each other, thereby achieving compression to knead the part of the human body inserted into the chamber 28 and covered by the pivotal rods 441.Further, a slide frame 48 is provided in the housing 20 for rotatably connecting the pivot rods 441 to the slide member 463. In this embodiment, the slide frame 48 is configured substantially as a polygonal structure having a number of lateral edges corresponding to the number of the pivot rods 441 / the second massage portions 26. The connecting end 444 of each pivot rod 441 is rotatably connected to a lateral edge of the slide frame 48 by a second pivot 481. Each second pivot pin 481 is mounted substantially parallel to a corresponding first pivot pin 442 of the same pivot rod 441.The slide frame 48 may be separately formed and then fitted with the slide member 462, or may be integrally formed with the slide member 462 as long as the slide frame 48 can be moved with the slide member 462. In this embodiment, the second pivot pin 481 is integrally formed with the slide frame 48, and a U-shaped groove 445 is defined in the connecting end 444 of the pivot rod 441 to facilitate the joining of the second pivot pin 481 and the pivot rod 441. It should be appreciated that in other embodiments, the second pivot pin 481 may be separately formed and then assembled with the slide frame 48 and / or pivot rod 441.In this embodiment, as shown in FIG. 5, the slide frame 48 is formed substantially rectangular, and four pivot rods 441 are provided to be connected to the four lateral edges of the slide frame 48. Accordingly, the housing 20 includes four second massage portions 26 disposed around the first massage portion 24 and for receiving the pivotal ends 443 of the four pivot rods 441. It should be noted that the number of the second massage portions and / or the pivot rods is not limited to four as in the above-mentioned embodiment.FIG. 8 shows a second stimulation module 40 aof a massage device according to an alternative embodiment. In this embodiment, the second stimulation module 40 aincludes three pivot rods 441 connected to the transmission unit 46 by a substantially hexagonally shaped slide frame 48 a. Preferably, the massage device can have 3 to 8 pivot rods 441, e.g. five or six pivot rods 441. Accordingly, there may be 3 to 8 second massage portions 26. The slide frame 48 may be configured with a number of lateral edges greater than or equal to the number of the pivot rods 441 / the second massage portions 26.In operation, the slide member 462 and the slide frame 48 move together in the Z direction under the drive of the gear 42, and in turn, the pivot rods 441 simultaneously swing about the first pivot pins 442 with respect to the housing 20 and swing about the second pivot pins 481 with respect to the slide frame 48, so that the pivot ends 443 and the second massage portions 26 swing toward or away from the first massage portion 24 for kneading the human body as in the case of being kneeled with a human hand, and thus the user more easily comes to an orgasm by the present massage apparatus 100.In this embodiment, the first pivot pin 442 faces the connecting end 444 and faces away from the pivot end 443 of the pivot rod 441, so that the pivot end 443 of the pivot rod 441 can rotate about the first pivot pin 442 with a larger swing amplitude even when the swing angle of the pivot rod 441 about the second pivot pin 481 is small. Accordingly, the second massage portions 26 driven by the pivot rods 441 can provide enhanced stimulation to the human body.Referring again to FIGS. 3 and 4, a control board 60 is mounted in the housing 20 and electrically connected to the rotary motor 421 and the vibration motor 30 to drive their operation, such as the vibration frequency of the vibration motor 30, the rotation speed of the rotary motor 42, and the like, according to user instructions. Joysticks 62, such as mechanical buttons or touch buttons, may be provided on the outer housing 20a for input of user instructions. Further, a battery 64, preferably a rechargeable battery, is disposed in the main portion 22 of the housing 20 and electrically connected to electrical components such as the rotation motor 421, the vibration motor 30, and the like through the electric power supply control board 60.In operation, the second stimulation module 40 alone can be switched on in order to achieve a stimulation effect on the human body, such as on the breast, by vibration of the second massage sections 26. Alternatively, the first stimulation module 30 alone may be turned on to achieve a stimulation effect on the human body by the high-frequency vibration of the first massage portion 24. Still alternatively, the first stimulation module 30 and the second stimulation module 40 may be simultaneously turned on to provide a combined stimulation effect on the human body. For enhancing user comfort, the second massage portions 26 and the first massage portion 24 of the housing 20 are configured as a soft single-layer structure, i.e., without the hard inner housing 24.In the massage device 100 described above, the chamber 28 is formed between some second massage portions 26 to accommodate a part of the human body such as the chest. The second massage sections 26 swing toward or away from the first stimulation module 30 to knee the portion of the human body located in the chamber 28, which is more suitable for a user, in particular for stimulation of the user's breast. It is understood that stimulation of the breast can not only improve sexual experience in sex life, but also plays a role for the treatment of breast diseases in the healthcare field. In addition, such a massage device can also be used for a user, such as to stimulate the oak of the penis.FIGS. 9 to 19 show a massage device according to a third embodiment of the present application.

Similarly to the first embodiment, the housing 20 cis configured with two layers, i.e., an inner hard layer and an outer flexible layer, on the main portion 22 cand with a single layer on the first massage portion 24 cand the second massage portions 26 c. Preferably, the first massage portion 24c and the second massage portions 26c are integrally formed with the outer flexible layer of the main portion 22c.The first massage portion 24 cis formed substantially in a columnar shape, a distal end thereof being configured in a dome shape. Each of the second massage portions 26 cis curved and plate-shaped. In this embodiment, the adjacent second massage portions 26 care connected to each other so that a chamber 28 cformed between the second massage portions 26 cis substantially closed in the circumferential direction, thereby more effectively enclosing the user's chest in use. Preferably, a joint between two adjacent second massage portions 26 cis formed substantially in a V shape to facilitate the vibration of the second massage portions 26 c.Referring to FIGS. 11 and 15, the stimulation assembly includes a first stimulation module 30 c, such as a vibration motor, provided in the first massage portion 24 cof the housing 20 cto vibrate the first massage portion 24 c, a second stimulation module 40 cto vibrate the second massage portions 26 cto or away from the first massage portion 24 c, and a third stimulation module 50 cto vibrate the first massage portion 24 c.Referring also to FIGS. 16 and 17, the second stimulation module 40 ccomprises a gear 42 c, a pivoting unit 44 cand a transmission unit 46 cconnected between the gear 42 cand the pivoting unit 44 c.The transmission unit 46 cis configured to convert the rotation of the transmission 42 cin a linear reciprocating motion. As shown in FIG. 16, the transmission unit 46 cincludes a fixed member 72 c, a rotating member 74 c, and a sliding member 76 ccooperating with each other. The rotary component 74 cis thereby connected in a force-transmitting manner to an output shaft 429 cof the transmission 42 c. Preferably, a steering gear unit 43c is provided between the output shaft 429c and the rotating member 74c to change the direction of power transmission and thereby simplify the arrangement of the transmission 42c.The steering gear unit 43c may be composed of two bevel gears so as to allow the direction of power transmission to be changed by 90 degrees. As shown in FIG. 16, the transmission 42 cis arranged such that the output shaft 429 cextends therefrom in the X direction. An output shaft 431 cof the steering gear unit 43 cextends in the Z direction. In other embodiments, the output shaft 431 cof the steering gear unit 43 cmay be inclined to the output shaft 429 cof the transmission 42 c. In other embodiments, the rotating member 74 cmay be directly connected to the output shaft 429 cof the transmission 42 c, so that the steering gear unit 43 cis omitted.The fixed member 72 cis fixedly mounted in the housing 20 c, and a first slide groove 721 cextending in the Z direction is defined in the fixed member 72 c. The rotating member 74 cis rotatably mounted in the housing 20 c, and in the rotating member 74 c, a second slide groove 741 cthat extends spirally in the circumferential direction is defined. The slide member 76 ccooperates with the first slide groove 721 cand the second slide groove 741 cin parallel to convert the rotation of the rotation member 74 cin a linear reciprocating motion of the slide member 76 cin the Z direction.In this embodiment, a mounting seat 78 cis provided in the housing 20 c, more specifically, in an inner housing 201 cto accommodate the steering gear unit 43 c, the fixed member 72 c, the rotating member 74 c, and the sliding member 76 c. A pair of locking apertures 781c are defined in the mounting seat 78c, and a pair of locking ridges 723c extend radially outward from the stationary member 72c and engage the locking apertures 781c to fixedly attach the stationary member 72c to the mounting seat 78c. In other embodiments, the locking ridges may be provided on the mounting seat 78c and the locking apertures may be defined in the stationary component 72c.The fixed member 72 cis hollow and cylindrical. The rotating member 74 cis configured as a rotating shaft and rotatably mounted in the fixed member 72 c. The slide member 76 cis configured as a hollow sleeve and slidably mounted about the fixed member 72 c. In this embodiment, the output shaft 431 cof the steering gear unit 43 cextends into the fixed member 72 cto be connected to one end (such as a lower end) of the rotating member 74 c. The rotating member 74 cand the output shaft 431 cmay be fixed in the circumferential direction by positive engagement, locking, etc. In operation, the rotating member 74 cis rotated with the output shaft 431 cabout a rotation axis extending in the Z direction.Referring to FIGS. 12, 17 and 18, a first sliding portion 761 cprotrudes radially inward from the sliding member 76 cand slidably engages with the first sliding groove 721 c, and a second sliding portion 763 cprotrudes radially inward from the first sliding portion 761 cand slidably engages with the second sliding groove 741 c. The first slide groove 721 cextends through a circumferential wall of the fixed member 72 cin the radial direction, so that the second slide portion 763 cmay extend into the second slide groove 741 cthrough the first slide groove 721 c. Preferably, the second slide groove 741 cis axis-symmetrical about the rotational axis of the rotating member 74 c.In operation, the rotating member 74 cis caused to rotate about its rotational axis (i.e., a central axis of the rotating member 74 c), and the second sliding portion 763 cengaged with the second sliding groove 741 cof the rotating member 74 capplies the sliding member 76 cin a tendency to rotate about the rotational axis. However, the first slide portion 761c, which is engaged with the first slide groove 721c of the fixed member 72c, prevents the rotation of the slide member 76c. Therefore, the first sliding portion 761c slides along the first sliding groove 721c and the second sliding portion 763c slides along the second sliding groove 741c, so that the sliding member 76c is vertically moved in the Z direction.In this embodiment, the first sliding portion 761 cand the second sliding portion 763 care separately formed and then fitted to the sliding member 76 c, which promotes the fitting of the fixed member 72 c, the rotating member 74 c, and the sliding member 76 c. In other embodiments, the first sliding portion 761 cand / or the second sliding portion 763 cmay be integrally formed with the sliding member 76 c, and the first sliding portion 761 cand the second sliding portion 763 cmay be integrally formed with each other.The pivot unit 44c includes a plurality of pivot rods 441c rotatably connected to a fixed frame 448c by a plurality of first pivot pins 442c. At this time, the fixed frame 448c is fixed in an inner case 201c. In this embodiment, the pivot rod 441 cis formed to be substantially plate-shaped and elongated. One end, preferably the end remote from the first pivot pin 442c, of the pivot rod 441c is configured as a pivot end 443c and extends into one of the second massage portions 26c of the housing 20c. Another end, preferably the end facing the first pivot pin 442c, of the pivot rod 441c is configured as a connecting end 444c for connection to the slide member 76c.In this embodiment, an opening 449 cis defined in a central portion of the fixed frame 448 c.

Another end (such as an upper end) of the slide member 76c extends into the opening 449c of the fixed frame 448c. Referring to FIG. 14, a plurality of rectilinear depressions 765 care defined in an outer peripheral wall of the upper end of the slide member 76 c, and the connecting ends 444 cof the pivot rods 441 crotatably engage with the rectilinear depressions 765 c.In operation, the slide member 76c is caused to move in the Z direction by the gear 42c which in turn causes the connecting ends 444c of the pivot rods 441c to move simultaneously in the Z direction. The connecting end 444 cis thus rotated in the rectilinear recess 765 c, and accordingly the entire pivot rod 441 cis rotated about the first pivot pins 442. Finally, the swing ends 443 cand the second massage portions 26 chaving the swing ends 443 cinserted therein swing toward or away from each other to knead the human body in the chamber 28 c,as in the case of being crumpled with a human hand, thereby providing more comfortable sexual stimulation.Referring to FIGS. 16 and 17, the third stimulation module 50 cincludes a drive rod 52 c, a rotational component 54 c, and a drive component such as a rotational motor, a gear, and the like.The drive rod 52 ccomprises a first end portion 521 chaving a first central axis X 1 and a second end portion 523 chaving a second central axis X 2.
