[0007] In order to allow those skilled in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. In addition to the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0008] It should be noted that when one component is referred to as "connected" to another component, it can be directly connected to the other component or indirectly connected through one or more intermediate components.

[0009] As used herein, the terms "longitudinal," "lateral," "top," "bottom," "inner," "outer," "central," "axial," "radial," "circumferential," and the like, used to denote directions or positions, are intended solely to facilitate the description of the present application and simplify the description based on directions or positions shown in the drawings, and do not indicate or imply that the devices or components referred to must be constructed or operated in a particular orientation, and therefore should not be understood as limitations of the present application.

[0010] Unless otherwise specified or limited, the specific meaning of all technical and scientific terms used in the specification can be specifically understood by those skilled in the art. The terms used in this specification are used only to describe specific embodiments and are not intended to limit the specification.

[0011] 1 to 6, a sex toy 100 according to a first embodiment of the present application is shown. The sex toy 100 comprises a shell 20 and a stimulation assembly mounted within the shell 20.

[0012] As shown in FIGS. 1 to 6, the shell 20 is generally configured as a human hand, and includes a main body 22 configured as a palm and several massage sections 24 extending from opposite sides of the main body 22. Each massage section 24 is long, curved, and cylindrical, and configured as a finger. Two fixing sections 26 extend from opposite sides of the main body 22. Each fixing section 26 is configured as a curved sheet and is aligned in a row on the same side of the massage sections 24 and the main body 22.

[0013] Referring also to Figure 2, the massaging portions 24 of the shell 20 cooperatively define a first internal chamber 241 therebetween. Referring also to Figure 4, the fixing portions 26 of the shell 20 cooperatively define a second internal chamber 261 therebetween. The first internal chamber 241 and the second internal chamber 261 communicate with each other and cooperatively define a stimulation chamber that is substantially cylindrical and configured to receive a sensitive part of the human body, such as a male sexual organ, therein.

[0014] 3 to 6, the shell 20 has a double-layer structure and includes an outer shell 20a and an inner shell 20b inside the outer shell 20a. The inner shell 20b may be made of a hard material such as plastic or metal, and provides support for the stimulation assembly attached to the inside of the shell 20. The outer shell 20a may also be made of a soft material such as silicone or rubber to directly contact the male genitalia, thereby providing the sex toy 100 with a high strength and comfortable use experience as a whole.

[0015] 6 and 7, the stimulation assembly of this embodiment includes a first stimulation module 40, a second stimulation module 50 and a third stimulation module 60.

[0016] 8a and 8b, the first stimulation module 40 includes a first motor 42, a swinging unit 44, and a first transmission unit 46 connected between the first motor 42 and the swinging unit 44. The swinging unit 44 includes a first swinging bar 441 and a second swinging bar 443 that are arranged substantially symmetrically to each other. During operation of the first motor 42, the first swinging bar 441 and the second swinging bar 443 are driven to swing toward or away from each other relative to the shell 20, thereby achieving a gripping action that grips the male organ into the stimulation chamber 28.

[0017] The first swing bar 441 includes a first connecting arm 441a and a first swing arm 441b connected to each other. Preferably, the first connecting arm 441a and the first swing arm 441b are integrally formed as a single unit, and an included angle is formed between them. The joint between the first connecting arm 441a and the first swing arm 441b is rotatably connected to the inner shell 20b by a first pivot 442. The distal end of the first connecting arm 441a remote from the first swing arm 441b is connected to the first transmission unit 46, and the distal end of the first swing arm 441b remote from the first connecting arm 441a is configured as a first swing end 441c, which extends into one of the massage elements 24 on a first lateral side of the shell 20 (e.g., the left side in FIG. 8a).

[0018] Similarly, the second swing bar 443 includes a second connecting arm 443a and a second swing arm 443b that are connected to each other and angled relative to each other. The junction of the second connecting arm 443a and the second swing arm 443b is rotatably connected to the inner shell 20b by a second pivot 444. The distal end of the second connecting arm 443a remote from the second swing arm 443b is connected to the first transmission unit 46, and the distal end of the second swing arm 443b remote from the second connecting arm 443a is configured as a second swing end 443c, which extends into one of the massage elements 24 on a second lateral side of the shell 20 (e.g., the right side in FIG. 8a).

[0019] The tips of the first and second connecting arms 441a, 443a can be driven to move along a first direction, such as the Z direction, and therefore the first and second swinging arms 441b, 443b can swing around the first pivot axis 442 and the second pivot axis 444, respectively.

[0020] The first pivot shaft 442 and the second pivot shaft 444 both extend along a second direction, such as the X direction, and are parallel to and spaced apart from each other. The first swing end 441c and the second swing end 443c face each other in a third direction, such as the Y direction. During operation, the first motor 42 drives the first connecting arm 441a and the second connecting arm 443a via the first transmission unit 46 to synchronously reciprocate in the Z direction, causing the first swing bar 441 to swing around the first pivot shaft 442 and the second swing bar 443 to swing in the opposite direction around the second pivot shaft 444, causing the first swing end 441c and the second swing end 443c to swing toward or away from each other, thereby achieving a meshing action.

[0021] In this embodiment, the swing unit 44 further includes a third swing bar 445 and a fourth swing bar 447, which are arranged substantially symmetrically with respect to each other. The first pivot 442 extends within a central portion of the third swing bar 445 and rotatably connects the third swing bar 445 to the inner shell 20b, and the second pivot 444 extends within a central portion of the fourth swing bar 447 and rotatably connects the fourth swing bar 447 to the inner shell 20b. The first pivot 442 may be fixed to the first and third swing bars 441, 445 so as to rotate along them, or may be fixed to the inner shell 20b. The second pivot 444 may be fixed to the second and fourth swing bars 443, 447 so as to rotate along them, or may be fixed to the inner shell 20b.

[0022] The third swing bar 445 has one end configured as a third swing end 445c, extending into the other massage part 24 on the first lateral side of the shell part 20, and the other end fixedly connected to the first connecting arm 441a of the first swing bar 441 by a third pivot 446, so that the third swing bar 445 can swing together with the first swing bar 441 around the first pivot 442. The fourth swing bar 447 has one end configured as a fourth swing end 447c, extending into the other massage part 24 on the second lateral side of the shell part 20, and the other end fixedly connected to the second connecting arm 443a of the second swing bar 443 by a fourth pivot 448, so that the fourth swing bar 447 can swing together with the second swing bar 443 around the second pivot 444. The third swinging end 445c and the fourth swinging end 447c face each other in the Y direction and can swing toward or away from each other to achieve a biting action.

[0023] In this embodiment, the shell 20, specifically the outer shell 20a, is provided with four massage units 24, each accommodating the four swinging ends 441c, 443c, 445c, and 447c, respectively, corresponding to the first to fourth swinging ends 441c, 443c, 445c, and 447c of the first to fourth swinging bars 441, 443, 445, and 447 of the swinging unit 44 of the first stimulation module 40. During operation, the massage units 24 swing together with the swinging ends 441c, 443c, 445c, and 447c, engaging the male genitalia with the stimulation chamber 28. This type of sex toy can simulate a human hand holding and pinching the male genitalia, thereby providing better stimulation to the user.

[0024] It should be understood that the number of the rocking bars of the rocking unit is preferably a plurality, such as 2, 3, 4, 6, 8, etc., but should not be limited to a specific embodiment. And the number of massage parts of the shell part may be designed similarly to the rocking bars, so that they are accommodated and rock with the rocking ends of the rocking bars, respectively.

[0025] 9a to 9d show alternative embodiments of the oscillating unit. FIG. 9a shows an oscillating unit 44a having a first oscillating bar 441 and a second oscillating bar 443, where the two oscillating bars 441, 443 are arranged substantially symmetrically with respect to each other in the Y direction. FIG. 9b shows an oscillating unit 44b having three oscillating bars 441, 443 arranged in a staggered manner in the X direction, where two first oscillating bars 441 are located on the same lateral side and one second oscillating bar 443 is located on the opposite lateral side. FIG. 9c shows an oscillating unit 44c having five oscillating bars 441, 443, where four first oscillating bars 441 are located on the same lateral side and one second oscillating bar 443 is located on the opposite lateral side. Figure 9d shows a swing unit 44d having six swing bars 441, 443, where three first swing bars 441 are provided on one side and three second swing bars 443 are provided on the opposite side.

[0026] 8a and 8d, in this embodiment, the first motor 42 is a rotary motor and has a rotary shaft 421 for outputting torque. The first transmission unit 46 is configured to convert the rotation of the first motor 42 into reciprocating motion along a first direction, thereby moving the tips of the first and second connecting arms 441a, 443a in the first direction. The first transmission unit 46 includes a first eccentric wheel 461 and a sliding piece 462.

[0027] The first eccentric ring 461 is coupled to the rotating shaft 421 of the first motor 42. In this embodiment, the first eccentric ring 461 is generally circular and has a central hole 463 defined in its center for inserting the rotating shaft 421 therein. The central hole 463 of the first eccentric ring 461 has a non-circular shape, such as a D-shape, and the cross section of the rotating shaft 421 has a shape that matches the cross section of the central hole 463. After the rotating shaft 421 is inserted into the central hole 463 of the first eccentric ring 461, relative rotation therebetween is limited due to shape matching, so that the first eccentric ring 461 can rotate together with the rotating shaft 421 of the first motor 42.

[0028] The first rod 464 extends outward from the periphery of the first eccentric wheel 461, i.e., the first rod 464 is eccentrically disposed on the first eccentric wheel 461. The first rod 464 is substantially parallel to the rotation axis 421 of the first motor 42. While the first eccentric wheel 461 rotates together with the rotation axis 421 of the first motor 42, the first rod 464 rotates around the rotation axis 421. In this embodiment, the rotation axis 421 extends along the X direction, and the first rod 464 rotates around the rotation axis 421 in the YZ plane. In other words, the first rod 464 is displaced in both the Y direction and the Z direction when driven by the first motor 42.

[0029] The sliding piece 462 defines an elongated sliding slot 465 therein, which is roughly strip-shaped and elongated in the Y direction. The first eccentric rod 464 engages with the elongated sliding slot 465 and is fixed relative to the sliding piece 462 in the Z direction, while being slidable relative to the sliding piece 462 in the Y direction. While the first eccentric rod 464 revolves around the rotation shaft 421, its displacement in the Y direction slides within the elongated sliding slot 465, preventing the sliding piece 462 from moving in the Y direction. However, its displacement in the Z direction causes the sliding piece 462 to reciprocate in the Z direction. As a result, the rotation of the first motor 42 is converted into reciprocating linear motion of the sliding piece 462 in the Z direction.

[0030] In this embodiment, the tip of the first connecting arm 441a defines a first slot 441d therein, and the tip of the second connecting arm 443a defines a second slot 443d therein. The second rod 466 extends outward from the sliding piece 462 along the X direction and is movably engaged with the first slot 441d and the second slot 443d. This allows the sliding piece 462 to drive the tips of the first and second connecting arms 441a, 443a to synchronously reciprocate in the Z direction. The first and second slots 441d, 443d can be strip-shaped in the extension direction of the first and second connecting arms 441a, 443a, allowing the second rod 466 more freedom to move within the first and second slots 441d, 443d.

[0031] In this embodiment, the sliding piece 462 is movably connected to the inner shell 20b by a fifth pivot 467 extending along the Z direction. The fifth pivot 467 movably extends within the sliding piece 462, thereby guiding the movement of the sliding piece 462 in the Z direction. Preferably, one fifth pivot 467 is provided at each end of the sliding piece 462 in the Y direction, which can more stabilize the movement of the sliding piece 462 in the Z direction and therefore more stabilize and strengthen the oscillation of the oscillating ends 441c, 443c, 445c, and 447c of the oscillating unit 44 driven by the second rod 466 of the sliding piece 462. In other words, the stimulation intensity of each massage section 24 of the sex toy 100 is more uniform, and the overall stimulation effect is better.

[0032] 5 and 6, the second stimulation module 50 further includes at least one vibration member, such as a second motor 52, preferably a vibration motor. The second motor 52 is mounted on the massage portion 24 of the shell 20 and is located adjacent to the distal end of the massage portion 24. The second motor 52 is configured to generate high-frequency vibrations on the male genitalia within the stimulation chamber 28. Preferably, there are several second motors 52, each mounted on one of the massage portions 24. During use, the first stimulation module 40 or the second stimulation module 50 may be activated separately, or the first stimulation module 40 and the second stimulation module 50 may be activated simultaneously.

[0033] 10a and 10b, the third stimulation module 60 includes a third motor 62 having a rotation axis 621, a third eccentric wheel 64 connected to the rotation axis 621 of the third motor 62, and a swing rod 66 connected to the third eccentric wheel 64. The third eccentric wheel 64 has a third rod 641 extending therefrom, which is parallel to the rotation axis 621 of the third motor 62. The swing rod 66 has the third rod 641 extending outward from its outer periphery and is generally perpendicular to the third rod 641. One end of the swing rod 66 is rotatably attached around the third rod 641, and the other end is embedded in the main body 22 of the shell 20, specifically in a portion of the main body 22 corresponding to the second internal chamber 261 between the fixing portions 26.

[0034] Preferably, a head portion 661 having a diameter larger than that of the other portion of the swing rod 66 embedded in the main body portion 22 is formed at the other end of the swing rod 66, improving the stability of the connection between the swing rod 66 and the main body portion 22. Preferably, in order to facilitate movement of the swing rod 66, the portion of the main body portion 22 corresponding to the head portion 661 of the swing rod 66 is configured with only the soft outer shell 20a, i.e., without the hard inner shell 20b, as shown in Figures 3 and 4.

[0035] 3 and 4, the rotation shaft 621 of the third motor 62 and the third rod 641 of the third eccentric wheel 64 both extend along the X direction, and the oscillating rod 66 extends along the Z direction. During operation, the rotation of the third motor 62 is converted into rotation of the oscillating rod 66 about the rotation shaft 621, which is then converted into reciprocating motion in the Z direction of the oscillating rod 66 and the portion of the body 22 adjacent to the head 661 of the oscillating rod 66, since the oscillating rod 66 is limited to moving in the X and Y directions due to engagement with the shell 20. At the same time, relative rotation occurs between the oscillating rod 66 and the third rod 641. That is, the third stimulation module 60 provides reciprocating motion in the Z direction to strike the male organ in the stimulation chamber 28.

[0036] The first and third stimulation modules 40, 60 provide stimulation to different parts of the male genitalia in different ways, thus achieving a better stimulation effect. It should be understood that the third stimulation module 60 may be activated separately or simultaneously used with the first stimulation module 40. To enhance user comfort, the massaging portion 24 of the shell 20, which forms the first internal chamber 241, and the fixed portion, which forms the second internal chamber 261, are configured with only the soft outer shell 20a, i.e., without the hard inner shell 20b.

[0037] 6 and 7, a battery 80, preferably a secondary battery, is disposed in the main body 22 of the shell 20 for supplying power to electrical components such as the first, second, and third motors 42, 52, and 62 of the sex toy 100. Furthermore, a control circuit board 82 is attached to the shell 20 and electrically connected to the first, second, and third motors 42, 52, and 62 for controlling their operations according to user instructions, such as controlling the vibration frequency of the second vibration motor 52 and the rotation speed of the rotation motors 42 and 62. Control buttons 84, such as mechanical buttons or touch buttons, may be provided on the outer shell 20a for inputting user instructions.

[0038] FIG. 11 shows a sex toy 100w according to a second embodiment of the present invention. This sex toy is similar to the previous embodiment, and for the same components, please refer to the description of the previous embodiment. This embodiment differs from the first embodiment mainly in the shape of the fixing portion 26w. Specifically, in this embodiment, the fixing portion 26w is cylindrical. The cylindrical fixing portion 26w defines a cylindrical second internal chamber 261w. One end of the fixing portion 26w adjacent to the massaging portion 24w is open, and the other end away from the massaging portion 24w is closed.

[0039] During use, the cylindrical fixing portion 26w can tightly encase the man's penis, particularly the glans penis, thereby further enhancing the stimulating effect of the sex toy 100w. It should be understood that in other embodiments, the end of the fixing portion 26w remote from the massaging portion 24w may also be open, allowing the glans penis to protrude from the cylindrical fixing portion 26w.

[0040] 12 to 17, a sex toy 100r according to a third embodiment of the present application is shown. The sex toy 100r includes a shell 20r composed of at least two massage portions 24r, a first stimulation module 40r, and a second stimulation module 50r. A stimulation chamber 28r for accommodating a male penis is defined between the at least two massage portions 24r. The at least two massage portions 24r include a first massage portion and a second massage portion disposed on opposite sides of the stimulation chamber 28r.

[0041] The first stimulation module 40r includes at least two sliding rods, such as a first sliding rod 241r and a second sliding rod 242r, which are arranged on opposite sides and extend into the at least two massage sections 24r of the shell section 20r. The first sliding rod 241r and the second sliding rod 242r extend into the first massage section and the second massage section, respectively. A driving mechanism 41r, such as a motor, is torque-transmittingly connected to the first sliding rod 241r and the second sliding rod 242r, and moves the first sliding rod 241r and the second sliding rod 242r toward or away from each other to change the radius of the stimulation chamber 28r at the position corresponding to the massage section 24r. The number of massage parts 24r / sliding rods 241r, 242r can be two, three, four or more. The more massage parts 24r there are, the larger the contact area with the penis in the stimulation chamber 28r will be, so that sufficient stimulation and massage effects can be achieved, and the user experience of the product will be improved.

[0042] In the present disclosure, the longitudinal direction refers to the extension direction of the stimulation chamber 28r, i.e., the insertion direction of the male penis into the stimulation chamber 28r, and the radial direction refers to the direction perpendicular to the extension direction of the stimulation chamber 28r.

[0043] On the other hand, the structure of the Sex Toy 100r is simple and compact, providing a more personalized and comfortable stimulating massage experience.

[0044] On the other hand, the sliding rods 241r, 242r can provide a more comprehensive stimulating massage effect to the male penis located within the stimulation chamber 28r, further improving the use experience of the product.

[0045] 14, 16, and 17, the first stimulation module 40r further includes a sliding member 420r driven by a rotating shaft 4121r of the driving mechanism 41r. When the rotating shaft 4121r rotates, the sliding member 420r moves along the longitudinal direction. Each of the first sliding rod 241r and the second sliding rod 242r includes at least one sliding body 13r slidably engaged with the sliding member 420r. When the sliding member 420r moves in the longitudinal direction, the sliding member 420r slides the first sliding rod 241r and the second sliding rod 242r in the radial direction.

[0046] That is, the first stimulation module 40r can convert rotational motion into linear motion, and the rotation of the rotation shaft 4121r of the first stimulation module 40r can slide the sliding member 420r along the longitudinal direction of the stimulation chamber 28r. The sliding member 420r and the sliding bodies 13r of the sliding rods 241r and 242r are slidably engaged with each other to drive the sliding bodies 13r to slide along a radial direction perpendicular to the longitudinal direction, thereby driving the first sliding rod 241r and the second sliding rod 242r to slide toward or away from each other along the radial direction.

[0047] 14, 16, and 17, in one embodiment, the first stimulation module 40r further includes a transmission mechanism 43r, which includes a rotating member 431r extending along the longitudinal direction and a second sliding block 432r cooperating with the rotating member 431r. The rotating member 431r is connected to the rotating shaft 4121r and rotates together with the rotating shaft 4121r. A second sliding groove 431ra is provided on the outer circumferential surface of the rotating member 431r. One end of the second sliding block 432r is slidably engaged in the second sliding groove 431ra, and the other end of the second sliding block 432r is fixed to the sliding member 420r. The sliding member 420r is slidable in the longitudinal direction together with the second sliding block 432r but is prevented from rotating together with the rotating member 431r. Therefore, as the rotating member 431r rotates, the second sliding block 432r engaged with the second sliding groove 431ra slides linearly along the longitudinal direction, causing the sliding member 420r fixed to the second sliding block 432r to slide linearly along the longitudinal direction.

[0048] In some embodiments, the second slide block 432r and the slide member 420r may be integrally formed as one piece.

[0049] Specifically, in one embodiment, the transmission mechanism 43r further includes a fixed member 433r fixed within the shell portion 20. The fixed member 433r is used to prevent the sliding member 420r from rotating together with the rotating member 431r. For example, the fixed member 433r has a first slide groove 4331r extending along the longitudinal direction, and the sliding member 420r has a first slide block 422r slidably engaged with the first slide groove 4331r. Preferably, the first slide groove 4331r and the first slide block 422r are configured to form-fit circumferentially so as to prevent relative rotation between the sliding member 420r and the fixed member 433r.

[0050] The other end of the second sliding block 432r may be fixedly connected to the first sliding block 422r, or the second sliding block 432r and the first sliding block 422r may be integrally formed as one piece.

[0051] The present disclosure does not limit the method of converting rotation into linear motion. As an example, the sliding member 420r of the first stimulation module 40r may be driven to move linearly by a threaded rod mechanism including a threaded rod threadably connected to the sliding member 420r.

[0052] Alternatively, torque transmission can be achieved using a cam mechanism, in which case the sliding member 420r can be configured as a driven part driven by a cam. The sliding member 420r is driven to move linearly by the rotation of the cam. The specific shape of the cam can be adapted to control the movement trajectory of the sliding member 420r.

[0053] Alternatively, torque transmission can be achieved using a gear-rack mechanism, in which rotation of a gear drives a meshed rack to move linearly. In particular, rotation of the gear can be converted into linear motion of the rack by meshing of the gear teeth with the rack. In this case, linear motion of the sliding member 420r can be achieved as long as the rack and the sliding member 420r are fixedly connected. Furthermore, known crank-slide mechanisms and other transmission mechanisms can also be used, but will not be described in detail herein.

[0054] In the present disclosure, the sliding body 13r is slidably engaged with the sliding member 420r, but the method for sliding the sliding body 13r in the radial direction while the sliding member 420r slides along the longitudinal direction is not particularly limited.

[0055] For example, in one embodiment, the sliding member 420r is provided with a wedge, and the sliding body 13r has an inclined surface that can engage with the wedge. When the sliding member 420r slides along the longitudinal direction, the wedge pushes the sliding body 13r through engagement with the inclined surface, causing it to slide along the radial direction.

[0056] In some embodiments, the slidable engagement between the sliding member 420r and each sliding body 13r is achieved by cooperation of the slot 421ra or 421rb with the protrusion 131r. In the embodiment shown in FIG. 17, the slots 421ra and 421rb are formed in the sliding member 420r, and the protrusion 131r is formed in each sliding body 13r. The protrusions 131r of the sliding bodies 13r of the first and second sliding rods 241r and 242r are slidably inserted into the slots 421ra and 421rb, respectively. The positions of the slots 421ra and 421rb and the protrusions 131r are not limited. That is, in other cases, the sliding member 420r may be configured with a protrusion 131r, and the sliding body 13r may be provided with corresponding slots 421ra and 421rb. When the sliding member 420r moves in the longitudinal direction, the protrusions 131r slide within the slots 421ra and 421rb, causing the sliding body 13r to move in the radial direction.

[0057] Specifically, the portions of the sliding member 420r adjacent to the first sliding rod 241r and the second sliding rod 242r are generally plate-like structures, and the first slot 421ra and the second slot 421rb are both formed in plate-like structures.

[0058] Both the first slot 421ra and the second slot 421rb are elongated. Referring to FIGS. 16, 17, and 22, both the first slot 421ra and the second slot 421rb are inclined with respect to the longitudinal direction. The protrusions 131r on the sliding bodies 13r of the first sliding rod 241r and the second sliding rod 242r are both configured as elongated pillars and are inserted into the first slot 421ra and the second slot 421rb, respectively. Because both the first slot 421ra and the second slot 421rb are inclined with respect to the longitudinal direction, the sliding bodies 13r of the first sliding rod 241r and the second sliding rod 242r are guided to move in the radial direction, thereby realizing the radial sliding of the first sliding rod 241r and the second sliding rod 242r.

[0059] In some embodiments, the first slot 421ra and the second slot 421rb extend gradually toward each other along the longitudinal direction away from the first sliding rod 241r and the second sliding rod 242r. In some embodiments, the first slot 421ra and the second slot 421rb extend gradually away from each other along the longitudinal direction away from the first sliding rod 241r and the second sliding rod 242r. That is, the radial distance between the first slot 421ra and the second slot 421rb gradually decreases or increases along the longitudinal direction.

[0060] In another embodiment, the extension direction of the first slot 421ra is parallel to the longitudinal direction, and the extension direction of the second slot 421rb is inclined at an angle relative to the extension direction of the first slot 421ra. Alternatively, the extension direction of the second slot 421rb is parallel to the longitudinal direction, and the extension direction of the first slot 421ra is inclined at an angle relative to the extension direction of the first slot 421ra. In this case, one of the first sliding rod 241r and the second sliding rod 242r corresponding to the inclined slot is driven to move in the radial direction, and the other of the first sliding rod 241r and the second sliding rod 242r does not move in the radial direction.

[0061] In other embodiments, one of the first sliding rod 241r and the second sliding rod 242r may be fixed within the shell portion 20r, and the other of the first sliding rod 241r and the second sliding rod 242r may be driven by the sliding member 420r.

[0062] Furthermore, in some embodiments, referring to FIGS. 16, 17, and 22, both the first slot 421ra and the second slot 421rb are inclined relative to the longitudinal direction, and the first slot 421ra and the second slot 421rb are arranged in a V-shape or a truncated V-shape. Therefore, an angle is defined between the first slot 421ra and the second slot 421rb. The range of the angle is not particularly limited and may be set to be greater than 0 degrees and less than 180 degrees as necessary. For example, the angle may be 30 degrees, 60 degrees, 90 degrees, 120 degrees, 150 degrees, etc. In the V-shape arrangement, first axial ends of the first slot 421ra and the second slot 421rb approach or intersect each other, and second axial ends of the first slot 421ra and the second slot 421rb are spaced apart from each other.

[0063] 13 and 14, in some embodiments, the drive mechanism 41r includes a first motor 441r and a gear assembly 412r connected to a rotary shaft 411r of the first motor 441r for torque transmission. The rotary shaft 4121r is configured as the output end of the gear assembly 412r. The gear assembly 412r can adjust the output speed of the rotary shaft 4121r and increase the output torque, thereby improving the control accuracy of the sex toy 100r, slowing the workload of the first motor 441r, and providing more stable stimulation to the male penis, thereby ensuring the reliability of the sex toy and the user's product experience.

[0064] In some embodiments, referring to Figures 12 to 17, the sex toy 100r is generally configured as a claw-like structure. The shell portion 20r includes an inner portion 20rb. At least two sliding rods 241r, 242r are disposed on opposite sides of the shell portion 20r. One end of each of the sliding rods 241r, 242r is slidingly connected to the shell portion 20r, and the tips of the first sliding rod 241r and the second sliding rod 242r protrude from the inner shell 20rb and extend toward each other. Preferably, the tips of the first sliding rod 241r and the second sliding rod 242r are curved toward each other. The at least two massage portions 24r and the base of the shell portion 20r surround a stimulation chamber 28r. Specifically, the inner shell 20rb includes an upper case 20rc and a lower case 20rd connected to each other, for example, by a snap fit. Inner shell 20rb defines a mounting cavity 21 therein, and first stimulation module 40r is disposed within mounting cavity 21 of shell portion 20r.

[0065] In some embodiments, referring to FIGS. 16, 17, and 22, the sex toy 100r further includes a guide member 3r, which is fixedly disposed within the inner shell 20rb to guide the radial sliding of the slider 13r. The guide member 3r has a guide slot 3ra for receiving the slider 13r. The guide slot 3ra extends generally radially. The shell 20r may be made of a hard plastic, such as, but not limited to, polypropylene (PP), polyvinyl chloride (PVC), or polycarbonate (PC). Thus, the shell 20r provides structural support for the components housed therein.

[0066] The guide slots 3ra extending generally in the radial direction means that the extension direction of the guide slots 3ra is the same as the radial direction or forms a slight angle with the radial direction. The angle range is not particularly limited and is preferably 0 to 20 degrees, for example, 0 degrees, 10 degrees, 20 degrees, etc. Exemplarily, in this embodiment, the guide slots 3ra penetrate two opposite sides of the guide member 3r in the radial direction, and the sliding body 13r is slidably inserted into the guide slots 3ra and is therefore slidable along the radial direction. The longitudinal slot walls of the guide slots 3ra prevent the sliding body 13r from moving in the longitudinal direction. The guide member 3r enhances the stability of the sliding body 13r when sliding in the radial direction.

[0067] 12 to 17, the shell 20r further includes an outer shell 20ra coated on the inner shell 20rb. The outer shell 20ra may be formed by injection molding and configured as a one-piece component. The outer shell 20ra includes at least two massage portions 24r for accommodating the sliding rods 241r and 242r.

[0068] In some embodiments, referring to FIGS. 15 to 17 , the second stimulation module 50r includes at least one vibration member, such as a vibration motor 52r. The number of vibration motors 52r may be one, two, or more. Each massage unit 24r may be provided with a second stimulation module 50r, or only one second stimulation module 50r may be disposed on one massage unit 24r. Alternatively, multiple second motors 52r may be provided on one massage unit 24r. The number and locations of the vibration motors 52r are not particularly limited herein. The vibration motor 52r may include, but is not limited to, an eccentric vibration motor, a linear vibration motor, an electromagnetic vibration motor, etc.

[0069] In some embodiments, the massager 24r includes a soft material disposed on at least one side facing the stimulation chamber 28r. Examples of the soft material include, but are not limited to, silicone, which is non-toxic, antibacterial, and chemically stable. Because the soft material is soft and gentle on the skin, the massager 24r contacts the man's penis within the stimulation chamber 28r through the soft material, thereby reducing friction and improving the comfort of the product.

[0070] The soft material of the massage portion 24r is configured as a flexible sleeve around the periphery, ensuring that all areas of the massage portion 24r are soft and gentle on the skin, further improving the user experience.

[0071] In some embodiments, the first sliding rod 241r includes a first support end 241ra, and the second sliding rod 242r includes a second support end 242ra. The first support end 241ra and the second support end 242ra extend within the massage portion 24r.

[0072] In this embodiment, the at least two sliding rods 241r, 242r include two first sliding rods 241r arranged on one side of the stimulation chamber 28r and two second sliding rods 242r arranged on the other side of the stimulation chamber 28r. The two first sliding rods 241r are arranged spaced apart from each other and connected to each other at their lower ends by a first beam 241rc. The two first sliding rods 241r are connected to a common sliding body 13r via the first beam 241rc. The two second sliding rods 242r are arranged spaced apart from each other and connected to each other at their lower ends by a second beam 242rc. The two second sliding rods 242r are connected to the common sliding body 13r via the second beam 242rc.

[0073] The sex toy 100r further includes a flexible cover 6r, which is an integral part. Preferably, the flexible sleeve is integrally formed with the flexible cover 6r, i.e., formed as a single unit. The flexible cover 6r may be formed by injection molding. The at least two massage portions 24r are partially disposed within the flexible cover 6r. The integral flexible cover 6r improves the integrity, sealing, product consistency, and aesthetics, which are beneficial to product sales and user experience.

[0074] Referring to Figure 17a, a sex toy 100s according to a fourth embodiment of the present disclosure is shown. The distal ends of the massage sections 24r may be connected to each other by a flexible member 93r. The flexible member 93r may be made of, but is not limited to, a stretchy, soft silicone. The flexible member 93r can further improve the enveloping effect of the stimulation chamber 28r of the sex toy 100r, thereby improving the user experience.

[0075] 18 to 23, a sex toy 100s according to a fifth embodiment of the present disclosure is shown. The sex toy 100s includes a shell 20s including at least two massage sections 24s and a first stimulation module 40s. The first stimulation module 40s includes a first sliding rod 241s and a second sliding rod 242s, which are disposed on opposite sides of the shell 20s and extend into the at least two massage sections 24s of the shell 20s, causing the first sliding rod 241s and the second sliding rod 242s to slide toward or away from each other. The detailed structure of the first stimulation module 40s can be seen in the embodiment of FIGS. 12 to 17, but will not be repeated here.

[0076] The shell 20s includes an outer tube 20sa and an inner tube 20sb disposed inside the outer tube 20sa. At least two massage portions 24s are defined as parts of the inner tube 20sb corresponding to the at least two sliding bars 241s, 242s. The inner tube 20sb is hollow and defines a stimulation chamber 100sa therein for accommodating a male penis. In this embodiment, the stimulation chamber 100sa is cylindrical. An accommodation chamber 100sb is formed between the outer tube 20sa and the inner tube 20sb. The at least two massage portions 24s are defined as parts of the inner tube 20sb corresponding to the at least two sliding bars 241s, 242s. In some embodiments, the at least two massage portions 24s may be integrally formed with the inner tube 20sb. In some embodiments, the inner tube 20sb may function as the massage portion 24s, and the first and second sliding rods 241s, 242s may be directly attached to the inner tube 20sb.

[0077] Illustratively, the outer tube 20sa is a generally hollow cylindrical structure. The inner tube 20sb is made entirely of a soft material such as silicone. A receiving chamber 100sb between the outer tube 20sa and the inner tube 20sb is used to place the first and second sliding rods 241s, 242s, etc. The first sliding rod 241s and the second sliding rod 242s are disposed on radially opposite sides of the inner tube 20sb.

[0078] As in the second embodiment, the first sliding rod 241s and the second sliding rod 242s of this embodiment can slide toward or away from each other. When the first and second sliding rods 241s, 242s slide toward each other, they push the inner tube 20sb inward, narrowing the radial dimension of the stimulation chamber 100sa and pinching the male penis accommodated therein.

[0079] In some embodiments, referring to FIG. 20, one longitudinal or axial end of the inner tube 20sb is open for insertion of the penis, and the other longitudinal or axial end is closed.

[0080] In some embodiments, referring to Figure 20, the inner tube 20sb is a one-piece component. The one-piece inner tube 20sb has better integrity, a tighter seal, and better product consistency and aesthetics, which are beneficial to product sales and user experience.

[0081] In some embodiments, the internal structure of the inner tube 20sb is more complex, for example, the inner tube 20sb is configured with non-uniform wall thickness, axial bends, etc. In this case, the inner tube 20sb can be formed by connecting multiple ring sections, which facilitates the processing and manufacturing of the product and reduces the manufacturing cost of the inner tube 20sb.

[0082] In some embodiments, referring to FIGS. 16 and 23 , the sex toy 100s further includes a battery 80s and a control circuit board 82s. The control circuit board 82s is electrically connected to the first stimulation module 40s. Because the battery 80s is electrically connected to both the control circuit board 82s and the first stimulation module 40s, a user can perform control operations, such as turning the first stimulation module 40s on and off and adjusting the mode, particularly the speed, of the first stimulation module 40s, using control buttons 84s on the control circuit board 82s. The battery 80s is used to supply power to the control circuit board 82s and the first stimulation module 40s. The battery 80s may be a removable battery 80s that can be easily replaced by the user, or a rechargeable battery 80s that is fixedly disposed within the sex toy 100s.

[0083] 18 to 23, the battery 80s and the control circuit board 82s are housed in the housing chamber 100sb. The battery 80s is disposed on a side of the first stimulation module 40s away from the massage portion 24s, and the control circuit board 82s is disposed on a longitudinal side of the inner tube 20sb.

[0084] 24 to 30, a sex toy 100h according to a sixth embodiment of the present application is shown. The sex toy 100h comprises a shell 20h and a stimulation assembly mounted within the shell 20h.

[0085] 26 and 29, the shell 20h has a double structure, with a flexible outer shell 201h and a hard inner shell 202h inside the outer shell 201h, and the massaging portions 24h and the rotating portion 28h are configured as a single layer structure, preferably as part of the flexible outer shell 201h, which provides a soft feel and a certain elastic cushioning effect, making the user feel more comfortable.

[0086] Similar to the first embodiment, the massage portions 24h are configured as elongated, curved pillars extending from two opposite sides of the main body portion 22h, respectively, and cooperatively define a first internal chamber 241h.

[0087] In this embodiment, the rotating portion 28h is generally cylindrical and is located at the axial end of the massaging portion 24h and spaced apart from the massaging portion 24h. The inner end of the rotating portion 28h closest to the massaging portion 24h is open, and the outer end of the rotating portion 28h remote from the massaging portion 24h is closed. The second internal chamber 281h is defined within the rotating portion 28h and communicates with the first internal chamber 241h through the open inner end of the rotating portion 28h. The first internal chamber 241h and the second internal chamber 281h cooperatively form a stimulation chamber 28 for accommodating the male genitalia therein.

[0088] During use, the male organ extends through the first internal chamber 241h between the massage portions 24h into the second internal chamber 281h inside the rotating portion 28h, with the glans penis enclosed in the closed end of the rotating portion 28h for greater comfort.

[0089] 29 and 30, the stimulation assembly includes a first stimulation module 40h configured to drive a massaging portion 24h to swing and pinch the rear end of the male organ, and a third stimulation module 70h configured to drive a rotating portion 28h to rotate and rub against the front end of the male organ. Thus, the massaging portion 24h functions as a first stimulation portion, and the rotating portion 28h functions as a second stimulation portion, acting on the male organ in different ways and thereby providing a better sexual experience.

[0090] As shown in FIGS. 31 to 33, the first stimulation module 40h includes a first motor 42h, a swinging unit 44h, and a first transmission unit 46h coupled between the first motor 42h and the swinging unit 44h.

[0091] The oscillating unit 44h includes a first oscillating bar 441h and a second oscillating bar 443h that are arranged substantially symmetrically to each other. The first oscillating bar 441h is rotatably mounted within the shell portion 20h by a first pivot 442h, and the second oscillating bar 443h is rotatably mounted to the shell portion 20h by a second pivot 444h. Each of the first and second oscillating bars 441h, 443h includes an oscillating arm having a tip end that is configured as an oscillating end 4412h, 4432h and engages with the massage portion 24h, and a connecting arm having a tip end that defines a slot 4414h, 4434h for connecting the oscillating unit 44h to the first transmission unit 46h.

[0092] The first transmission unit 46h includes a fixed member 47h, a rotating member 48h, and a sliding block 49h that cooperate with each other, and converts the rotation of the first motor 42h into the reciprocating linear motion of the sliding member 49h.

[0093] The fixed member 47h is fixedly installed on the shell portion 20h, and is fixedly connected to, for example, the motor housing of the first motor 42h with screws, etc. The fixed member 47h is provided with a first slide groove 471h extending along the X direction.

[0094] The rotating member 48h is connected to a rotating shaft 421h of a first motor 42h and rotates about an axis extending in the X direction by the action of the first motor 42h. The rotating member 48h and the rotating shaft 421h may be fixed in the circumferential direction via a metal fitting or the like so that they rotate synchronously. A second sliding groove 481h is provided in the rotating member 48h, and this sliding groove extends spirally in the circumferential direction of the rotating member 48h.

[0095] The sliding member 49h includes a first sliding block 491h and a second sliding block 492h, the first sliding block 491h being slidably engaged with a first sliding groove 471h of the fixed member 47h, and the second sliding block 492h being slidably engaged with a second sliding groove 481h of the rotating member 48h. Through cooperation between the first sliding block 491h and the first sliding groove 471h and cooperation between the second sliding block 492h and the second sliding groove 481h, the rotation of the first motor 42h is converted into reciprocating motion of the sliding member 49h in the X direction.

[0096] In the illustrated embodiment, the rotating member 48h is designed as a rotating shaft and is fixedly connected to the rotating shaft 421h of the first motor 42h. The fixed member 47h is cylindrical and attached to the periphery of the rotating member 48h. The sliding member 49h is cylindrical and attached to the periphery of the fixed member 47h. A first sliding block 491h protrudes inward from the sliding member 49h into the first sliding groove 471h of the fixed member 47h, and a second sliding block 492h extends through the first sliding groove 471h into the second sliding groove 481h of the rotating member 48h.

[0097] The second sliding block 492h is preferably an arc-shaped sheet that can adapt to the shape of the groove wall of the second sliding groove 481h. In this embodiment, the second sliding block 492h is formed separately and then fixedly connected to the first sliding block 491h, facilitating assembly of the sliding member 49h to the rotating member 48h. In some embodiments, the second sliding block 492h and the first sliding block 491h may be integrally formed as one piece.

[0098] 33 and 35, the second slide groove 481h includes a first helical segment 483h and a second helical segment 485h that are symmetrically arranged. The first helical segment 483h extends clockwise from the first base end A1 to the first tip end B1, and the second helical segment 485h extends counterclockwise from the first base end A1 to the first tip end B1. The first base end A1 and the first tip end B1 are arranged at a fixed interval in the axial direction of the rotating member 48h.

[0099] While the second sliding block 492h slides along the second sliding groove 481h from the first base end A1 to the first tip end B1, the sliding member 49h moves away from the fixed member 47h in the X direction. While the second sliding block 492h slides along the second sliding groove 481h from the first tip end B1 to the first base end A1, the sliding member 49h moves toward the fixed member 47h in the X direction. As a result, due to the rotation of the rotating member 48h, the sliding block 49h performs a linear reciprocating motion in the X direction.

[0100] In the illustrated embodiment, the first proximal end A1 and the first distal end B1 of the second slide groove 481h are located on the same base of the rotating member 48h, and the span of the first helical segment 483h or the second helical segment 485h is a full circle in the circumferential direction. In some embodiments, the first proximal end A1 and the first distal end B1 may be located on opposite sides of the rotating member 48h, i.e., separated by a semicircle in the circumferential direction. In this case, the span of the first helical segment 483h or the second helical segment 485h in the circumferential direction may be a semicircle.

[0101] In some embodiments, the second sliding groove 481h may be formed on the rotating shaft 421h of the first motor 42h. In this case, the rotating member 48h may be omitted, or a part of the rotating shaft 421h having the second sliding groove 481h may be considered to be the rotating member 48h.

[0102] The fixed member 47h, the rotating member 48h, and the sliding member 49h cooperate with one another to form a first transmission unit 46h, which converts the rotation of the first motor 42h into the reciprocating motion of the sliding member 49h.

[0103] In this embodiment, the sliding member 49h is provided with two transmission rods 495h, and each transmission rod 495h is engaged with a slot 4414h of either the first or second swing bar 441h, 443h. The transmission rod 495h is inclined in the X direction in which the first and second pivots 442h, 444h extend and in which the sliding member 49h moves. With the transmission rod 495h inclined, movement of the transmission rod 495h and the sliding member 49h in the X direction lifts or presses down the tips of the connecting arms of the swing bars 441h, 443h.

[0104] As a result, the swinging ends 4432h of the first and second swinging bars 441h, 443h are driven to swing toward or away from each other around their corresponding pivots 442h, 444h as rotation centers, which in turn drives the massage units 24h to swing toward or away from each other. In this embodiment, the slots 4414h at the ends of the connecting arms of the swinging bars 441h, 442h are generally U-shaped, which facilitates the movement and rotation of the transmission rods 495h within the slots 4414h.

[0105] In this embodiment, a sliding frame 497h is installed on the first motor 42h and the first transmission unit 46h and is connected to a sliding member 49h of the first transmission unit 46h. Specifically, two connecting rods 498h are provided on each of the opposing sides of the sliding member 49h, and two openings 499h are provided in the sliding frame 497h. Each connecting rod 498h engages with a corresponding opening 499h to fix the sliding frame 497h to the sliding member 49h in the X direction. The two transmission rods 495h are provided on the sliding frame 497h and are located at the end of the sliding frame 497h away from the openings 499h, facilitating connection with the swinging unit 46h.

[0106] In other embodiments, the connecting rod 498h may be provided on the sliding frame 497h, and the opening 499h may be defined in the sliding frame 497h. In other embodiments, the sliding frame 497h and the sliding member 49h may be fixed together in the X direction by screws, snap-fitting, bonding, etc. In other embodiments, the transmission rod 495h may be formed directly on the sliding member 49h, thereby eliminating the need for the sliding frame 497h.

[0107] In this embodiment, as shown in FIG. 28, the second stimulation module 50h includes at least one vibration member 52h such as a vibration motor, and the at least one vibration member 52h is provided on the massage part 24h, so that the massage part 24h can vibrate at a high frequency when oscillating, further enhancing the stimulating effect on the male genitals.

[0108] 34 and 35, the third stimulation module 70h includes a drive motor, a rotating shell part 74h mounted around the rotating part 28h, and a second transmission unit 76h connected between the rotating shell part 74h and the drive motor. In this embodiment, the first motor 42h also functions as a drive motor for the second stimulation module 70h. That is, the massage part 24h and the rotating part 28h are driven by the same component, i.e., the first motor 42h.

[0109] The rotating shell portion 74h is made of a hard material such as plastic or metal. The hardness of the rotating shell portion 74h is greater than that of the rotating portion 28h, so that the rotating portion 28h is supported and the torque of the first motor 42h is more effectively transmitted to the rotating portion 28h. Preferably, the rotating portion 28h is integrally formed inside the rotating shell portion 74h by overmolding, so that the rotating shell portion 74h and the rotating portion 28h can be driven to rotate synchronously.

[0110] The second transmission unit 76h may be a gear transmission unit including multiple gears that mesh with each other. One of the gears functions as an input wheel 761h and is connected to the rotating shaft 421h of the first motor 42h. The other gear functions as an output wheel 763h and is connected to the rotating shell 74h. The input wheel 761h and the output wheel 763h may be directly meshed with each other, or one or more intermediate gears 756h may be provided between the input wheel 761h and the output wheel 763h.

[0111] In this embodiment, a bearing seat 741h extends outward from the rotating shell portion 74h, and a central shaft 764h of an output wheel 763h of the second transmission unit 76h is inserted into the bearing seat 741h to drive the rotating shell portion 74h and the rotating portion 28h.

[0112] The second transmission unit 76h can transmit power over a long distance between the first motor 42h and the rotating part 28h, and can also change the direction of power transmission, facilitating the placement of the first motor 42h. In other embodiments, the second transmission unit 76h may be a pulley transmission unit, a worm gear transmission unit, or a combination of multiple transmission units, as long as it can rotate the rotating part 28h.

[0113] In this embodiment, the input wheel 761h of the second transmission unit 76h is coupled to a transmission rod 487h extending from the rotating member 48h. That is, the input wheel 761h is coupled to the first motor 42h via the rotating member 48h. In some embodiments, the input wheel 761h may be directly coupled to the rotating shaft 421h of the first motor 42h. Also, the rotating shell 74h may be directly coupled to the rotating member 48h or the rotating shaft 421h of the first motor 42h, omitting the second transmission unit 76h.

[0114] In some embodiments, referring to FIG. 26, a vibration motor 53h can be embedded in the rotating part 28h, so that the rotating part 28h can vibrate at a high frequency during rotation, further enhancing the stimulating effect on the male genitals.

[0115] As shown in Figure 26, in this embodiment, the shell portion 20h is generally L-shaped overall. The massage portion 24h is provided on the upper side of the shorter side of the shell portion 20h, and the rotating portion 28h is provided on the inside of the longer side of the shell portion 20h. Preferably, the inner wall of the rotating portion 28h surrounding the second internal chamber 281h is provided with a plurality of protrusions 283h, such as convex points, convex bulges, convex pillars, or convex bands, to enhance the stimulating effect on the male genitalia. It should be understood that protrusions may also be provided on the inner wall of the massage portion 24h surrounding the first internal chamber 241h.

[0116] 36 to 38, a sex toy 100i according to a seventh embodiment of the present application is shown. The sex toy 100i comprises a shell 20i and a stimulation assembly mounted within the shell 20i.

[0117] Similar to the second embodiment, the shell 20i includes a main body 22i, a plurality of massage portions 24i extending from opposite sides of the main body 22i, and a rotating portion 28i provided at the axial end of the massage portions 24i and spaced apart from the massage portions 24i. The massage portions 24i cooperatively define a first internal chamber 241i. A second internal chamber 281i is defined within the rotating portion 28h and communicates with the first internal chamber 241i. The first internal chamber 241i and the second internal chamber 281i cooperatively form a stimulation chamber 281i for receiving the male genitalia therein.

[0118] The stimulation assembly includes a first stimulation module 40i configured to drive the massage portion 24i to oscillate, and a third stimulation module 70i configured to drive the rotation portion 28i to rotate.

[0119] The second stimulation module 40i includes a gearbox 42i, a swinging unit 44i, and a transmission unit 46i connected between the gearbox 42i and the swinging unit 44i. The swinging unit 44i includes a first swinging bar 441i rotatably mounted within the shell 20i by a first pivot 442i and a second swinging bar 443i rotatably mounted to the shell 20i by a second pivot 444i. Each of the first and second swinging bars 441i, 443i includes swinging ends 4412i, 4432i, each of which includes a swinging arm having a distal end that engages with the massage part 24i and a connecting arm having a distal end that defines a slot 4414i, 4434i for connecting the swinging part 44i to the first transmission unit 46i.

[0120] The first transmission unit 46i includes a first eccentric wheel 461i and a sliding piece 462i. The first eccentric wheel 461i is connected to the rotary shaft 421i of the first motor 42i. The sliding piece 462i defines a sliding groove 465i therein, which is generally strip-shaped and elongated in the Y direction. The first rod 464i extends outward from the periphery of the first eccentric wheel 461i along the X direction and is slidably engaged with the elongated sliding slot 465i. The second rod 466i extends outward from the sliding piece 462i along the X direction and is movably and rotatably engaged with the slots 4414i and 4434i of the first and second swing bars 441i and 443i.

[0121] The third stimulation module 70i includes a drive motor, a rotating shell 74i mounted around the rotating part 28i, and a second transmission unit 76i connected between the rotating shell 74i and the drive motor. As in the second embodiment, the first motor 42i functions as the drive motor of the third stimulation module 70i.

[0122] The second transmission unit 76i includes an input wheel 761i connected to the first motor 42i in a transmission manner, an output wheel 763i connected to the rotating shell 74i, and several intermediate gears 765i arranged between the input wheel 761i and the output wheel 763i. In this embodiment, the input wheel 761i is attached and fixed around the first eccentric wheel 461i of the first stimulation module 40i. The intermediate gears 765i are arranged on both ends of the first motor 42i and connected by long rods 767i.

[0123] During operation, the first motor 42i drives the first rod 464i to rotate around the rotation axis 421i, thereby driving the sliding piece 462i to reciprocate in the Z direction, which in turn drives the first and second oscillation bars 441i, 443i to oscillate around the corresponding pivots 442i, 444i, respectively. This drives the massage units 24i to oscillate toward or away from each other. At the same time, the first motor 42i drives the rotation shell unit 74i via the third stimulation module 70i therebetween to rotate, which in turn rotates the rotating unit 28i. Therefore, the massage unit 24i and the rotating unit 28i simultaneously act on the male genitalia in different ways, providing a better sexual experience for the user.

[0124] 39 to 41, a sex toy 100j according to an eighth embodiment of the present application is shown. The sex toy 100j comprises a shell 20j and a stimulation assembly mounted within the shell 20j.

[0125] Similar to the second and third embodiments, the shell 20j includes a main body 22j, a plurality of massage units 24j provided on opposing sides of the main body 22j, and a rotating unit 28j provided at an axial end of the massage unit 24j. The stimulation assembly includes a first stimulation module 40j configured to drive the massage units 24j to oscillate, and a third stimulation module 70j configured to drive the rotating unit 28j to rotate.

[0126] In this embodiment, the first stimulation module 40j includes a first motor 42j, a swing unit 44j, and a transmission unit 46j connected between the first motor 42j and the swing unit 44j. The first transmission unit 46j includes a first eccentric wheel 461j and a sliding piece 462j cooperating with the first eccentric wheel 461j, and is similar to the first transmission unit 46i in the third embodiment (see FIG. 38), and details thereof will not be repeated here.

[0127] The swing unit 44j includes a first swing bar 441j and a second swing bar 443i that are arranged substantially symmetrically to each other. Each of the first and second swing bars 441j, 443j includes a swing arm having a tip end portion configured as a swing end 4412j, 4432j, which engages with the massage part 24j, and a connecting arm having a tip end portion defining a slot 4414j, 4434j for connecting the swing part 44j to the first transmission unit 46j.

[0128] The third stimulation module 70j includes a drive motor 72j, a rotating shell 74j mounted around the rotating unit 28j, and a second transmission unit 76j connected between the rotating shell 74j and the drive motor 72j. The second transmission unit 76j includes multiple gears that mesh with each other. That is, the massage unit 24j and the rotating unit 28j are driven by the first motor 42j and the drive motor 72j, respectively. The connection between the rotating unit 28j and the drive motor 72j may be simplified.

[0129] Furthermore, the movement of the massage unit 24j and the rotating unit 28j can be controlled separately. Specifically, the massaging unit 24j may be driven to oscillate while the rotating unit 28j remains stationary. Alternatively, the massaging unit 24j may be driven to oscillate while the rotating unit 28j remains stationary. It should be understood that the first motor 42j may be started to drive the massaging unit 24j to oscillate, and at the same time, the drive motor 72j may be started to drive the rotating unit 28j to oscillate. Therefore, the sex toy 100j of this embodiment can be used more conveniently.

[0130] 42 to 46, a sex toy 100k according to a ninth embodiment of the present application is shown. Sex toy 100k includes a shell 20k and a stimulation assembly mounted within shell 20k.

[0131] The shell portion 20k includes a main body portion 22k, a plurality of massage portions 24k provided on opposing sides of the main body portion 22k, and a rotating portion 28k provided at an axial end of the massage portion 24k and spaced apart from the massage portions 24k.

The third sliding groove 743k extends spirally in the circumferential direction of the rotating shell portion 74k. A fixing pin 79k is provided inside the shell portion 20k and is preferably fixed to the inner shell 202k. The fixing pin 79k is slidably engaged with the third sliding groove 743k of the rotating shell portion 74k. When the rotating shell portion 74k is driven to rotate, the fixing pin 79k slides along the third sliding groove 743k, moving the rotating shell portion 74k and the rotating portion 28k back and forth in the X direction, further enhancing the stimulating effect.

[0136] The third sliding groove 743k is configured symmetrically and includes two spiral segments extending in opposite directions from the second base end A2 to the second distal end B2. In this embodiment, the second base end A2 and the second distal end B2 are axially spaced a fixed distance apart. The circumferential span of each spiral segment of the third sliding groove 743k is a semicircle.

[0137] While the fixing pin 79k slides from the second base end A2 to the second tip end B2 along the third sliding groove 743k, the rotating part 28k slides toward the massage part 24k in the X direction. While the fixing pin 79k slides from the second tip end B2 to the second base end A2 along the third sliding groove 743k, the rotating part 28k slides away from the massage part 24k in the X direction.

Cooperation between the guide block 769m and the guide groove 745m allows smooth and stable movement of the rotating shell portion 74m and the rotating portion 28m in the X direction.

[0145] 50 to 57, a sex toy according to an eleventh embodiment of the present application is shown. In this embodiment, the sex toy 100t comprises a shell 20t and a stimulation assembly mounted within the shell 20t.

[0146] As shown in Figures 52 and 53, the shell 20t preferably has a double-layer structure and includes an outer shell 20ta and an inner shell 20tb integrally fixed to the inside of the outer shell 20ta. The inner shell 20tb may be made of a hard material such as plastic or metal and has relatively high strength, thereby providing support for the stimulation modules 50t, 40t attached to the inside of the shell 20t. The outer shell 20ta may be made of a soft material such as silicone or rubber for direct contact with the part of the human body that needs to be stimulated, thereby providing the sex toy 20ta with high strength and a comfortable user experience as a whole.

[0147] In one specific embodiment, the inner shell 20tb is first assembled with the components to be mounted inside the shell 20ta, such as the stimulation assembly, and then the outer shell 20ta is formed around the inner shell 20tb by overmolding, achieving a good sealing effect for the components inside the outer shell 20ta. The integrated outer shell 20ta provides waterproof and dustproof properties, making it easy to clean and store the sex toy 100t.

[0148] In this embodiment, the shell portion 20t includes a main body portion 22t, a second massage portion 26t, and a plurality of first massage portions 24t. The main body portion 22t is configured as a double-layer structure and provides support for a stimulation assembly, etc. The first massage portion 24t extends outward integrally from the outer shell 20ta of the main body portion 22t, and the second massage portion 26t is integrally surrounded and connected to the inner end of the first massage portion 24t. A chamber 28t is formed between the first massage portions 24t to accommodate a part of the human body (such as a breast) that needs to be stimulated therein. Preferably, the chamber 28t gradually decreases in size toward the inside. That is, the chamber 28t has a maximum size at its open side.

[0149] In this embodiment, the second massage portion 26t is dome-shaped, and the first massage portion 24t is sheet-shaped. Overall, the first and second massage portions 24t, 26t are configured like a flower, with the second massage portion 26t as the center of the flower and the first massage portion 24t as the petals. The outer ends of the first massage portion 24t extend slightly apart from each other, so that the chamber 28t is roughly bowl-shaped, which can better fit the shape of a human breast. Specifically, the depth "d" of the chamber 28t may be 3 to 300 mm, and the diameter "D" of the open side of the chamber 28t may be 10 to 200 mm.

[0150] In this embodiment, the first massage parts 24t are arranged evenly along the circumferential direction and symmetrically with respect to the second massage parts 26t. Specifically, the first massage parts 24t are spaced apart from one another in the circumferential direction, with a gap 29t between two adjacent first massage parts 24t. This prevents the first massage parts 24t from interfering with one another during operation. This allows the first massage parts 24t to have a larger oscillation amplitude and provide a stronger stimulation to the human body. It should be understood that the first massage parts 24t may be arranged asymmetrically and / or formed with different sizes or shapes.

[0151] In this embodiment, the second massage portion 26t of the shell portion 20t is configured as a vibrating portion, and the first massage portion 24t of the shell portion 20t is configured as a swinging portion. That is, the shell portion 20t is configured with two different massage portions for generating two different types of motion. Correspondingly, the stimulation assembly includes a second stimulation module 50t configured to drive the second massage portion 26t to vibrate, and a first stimulation module 40t configured to drive the first massage portion 24t to swing relative to the second massage portion 26t.

[0152] 52 and 53, the second stimulation module 50t includes at least one vibration member, such as a vibration motor, embedded in the second massage portion 26t of the shell portion 20t to generate high-frequency vibrations to the body part contained within the chamber 28t. When the sex toy 100t is used to stimulate the breasts, the vibration motor of the second stimulation module 50t drives the second vibration member 26t to stimulate the nipples, thereby achieving a better stimulation effect.

[0153] As shown in FIGS. 54 and 55, the first stimulation module 40t includes a gearbox 42t, a swing unit 44t, and a first transmission unit 46t coupled between the gearbox 42t and the swing unit 44t.

[0154] 56 , the gearbox 42t includes a rotary motor 421t and a reduction gear unit 423t coupled to the rotary motor 421t. The rotary motor 421t functions as a drive component of the first stimulation module 40t and has an output shaft 422t that rotates at high speed. The reduction gear unit 423t includes a gear housing 425t and a plurality of gears 427t disposed within the gear housing 425t. The gears 427t mesh with each other, and the reduction ratio of the entire gearbox 42t is determined according to the gear ratio between the meshed gears 427t of the reduction gear unit 423t. In one embodiment, the reduction ratio of the gearbox 42t is greater than or equal to 4:1 and less than or equal to 100:1.

[0155] The reduction gear unit 423t has an output shaft 429t, which functions as the output shaft of the gearbox 42. Due to the reduction effect of the reduction gear unit 423t, the speed of the output shaft 429t does not exceed 1000 rpm.

[0156] The first transmission unit 46t is configured to convert rotation of the output shaft 429t of the gear box 42t into reciprocating linear motion. In this embodiment, the first transmission unit 46t includes an eccentric wheel 461t and a sliding piece 462.

[0157] The eccentric 461t is coupled at its center to the output shaft 429t. In this embodiment, the eccentric 461t defines a central bore 463t for inserting the output shaft 429t therein. The central bore 463t has a non-circular shape, such as a D-shape, and the cross section of the output shaft 429t is shaped to match the cross section of the central bore 463t. After the output shaft 429t is inserted into the central bore 463t, relative rotation therebetween is limited due to the form fit, so that the eccentric 461t can rotate with the output shaft 429t of the gearbox 42t.

[0158] The eccentric rod 464t is eccentrically set on the eccentric wheel 461t and extends toward the sliding piece 462. The eccentric rod 464t is generally parallel to the output shaft 429t of the gearbox 42t. In this embodiment, as shown in FIG. 54, both the eccentric rod 464t and the output shaft 429t extend along the X direction. While the eccentric wheel 461t rotates together with the output shaft 429t, the eccentric rod 464t revolves around the output shaft 429t in the YZ plane. In other words, when driven by the gearbox 42t, the eccentric rod 464t generates displacement in both the Y and Z directions.

[0159] The sliding piece 462 defines an elongated sliding slot 465t therein, which is generally strip-shaped and extends in a direction perpendicular to the eccentric rod 464t, e.g., the Y direction. The eccentric rod 464t engages the sliding slot 465t and is fixed relative to the sliding piece 462t in the Z direction, while being slidable relative to the sliding piece 462t in the Y direction. As the eccentric rod 464t orbits the output shaft 429t, its displacement in the Y direction causes it to slide along the sliding slot 465t relative to the sliding piece 462t, while its displacement in the Z direction drives the sliding piece 462t to move in the Z direction therewith.

[0160] By cooperation of the eccentric rod 464t of the eccentric wheel 461t and the elongated sliding slot 465t of the sliding piece 462t, the rotation of the gear box 42t is converted into a reciprocating linear motion of the sliding piece 462t in the Z direction.

[0161] The swinging unit 44 includes a plurality of swinging bars 441t arranged around a sliding piece 462t. Each swinging bar 441t is rotatably connected to the shell 20t, preferably the inner shell 20tb, by a first pivot 442t. In this embodiment, the swinging bar 441t is generally sheet-shaped and elongated in the Z direction. One end of the swinging bar 441t, preferably the end farther from the first pivot 442t, is configured as a swinging end 443t and extends into one of the first massage sections 24t of the shell 20t. The other end of the swinging bar 441t, preferably the end adjacent to the first pivot 442t, is configured as a connecting end 444t connected to the sliding member 462t.

[0162] The first pivots 442t extend perpendicular to the Z direction, with a portion of the first pivots 442t extending along the X direction and a portion of the first pivots 442t extending along the Y direction. When the sliding pieces 462t move in the Z direction, the swinging bars 441t are driven to swing about the first pivots 442t. That is, the swinging bars 441t swing within the XZ plane or the YZ plane. The swinging ends 443t of all the swinging bars 441t swing toward or away from each other in synchronization, entering the chambers 28t and achieving a bite action that kneads the part of the human body covered by the swinging bars 441t.

[0163] A sliding frame 48t is provided inside the shell 20t to rotatably connect the swing bar 441t to the sliding member 463t. In this embodiment, the sliding frame 48t is configured as a polygonal structure having approximately the same number of side edges as the number of swing bars 441t / first massage units 24t. The connecting end 444t of each swing bar 441t is rotatably connected to the side edge of the sliding frame 48t by a second pivot 481t. Each second pivot 481t is set to be approximately parallel to the corresponding first pivot 442t of the same swing bar 441t.

[0164] It should be noted that the sliding frame 48t may be formed separately and then assembled to the sliding piece 4626, or may be formed integrally with the sliding piece 4626 as long as the sliding frame 48t can move together with the sliding piece 462t. In this embodiment, the second pivot 481t is formed integrally with the sliding frame 48t, and the connecting end 444t of the swing bar 441t is provided with a U-shaped groove 445 to facilitate assembly of the second pivot 481t and the swing bar 441t. It should be understood that in other embodiments, the second pivot 481t may be formed separately and then assembled to the sliding frame 48t and / or the swing bar 441t.

[0165] In this embodiment, as shown in Fig. 54, the sliding frame 48t is roughly square, and four swing bars 441t are provided to connect the four side edges of the sliding frame 48t. Correspondingly, the shell 20t includes four first massage parts 24t arranged around the second massage part 26t, and the swing ends 443t of the four swing bars 441t are housed inside the four second massage parts 26t, respectively. Note that the number of second massage parts and / or swing bars is not limited to four as in the above embodiment.

[0166] FIG. 57 shows a first stimulation module 40ta of a sex toy according to an alternative embodiment. In this embodiment, the first stimulation module 40ta includes three oscillating bars 40ta connected to the first transmission unit 46 by a sliding frame 48ta having a generally hexagonal shape. Preferably, the sex toy may have three to eight oscillating bars 441t, for example, five or six oscillating bars 441t. Correspondingly, there may be three to eight first massage portions 24t. The sliding frame 48t may be configured with side edges in a number equal to or greater than the number of oscillating bars 441t / first massage portions 24t.

[0167] During operation, the sliding member 462t and the sliding frame 48t are driven by the gearbox 42 to move together in the Z direction, which then drives the swinging bar 441t to swing around the first pivot 442t relative to the shell portion 20t, and simultaneously swing around the second pivot 481t relative to the sliding frame 48t, causing the swinging end 443t and the first massage portion 24t to swing towards or away from the second massage portion 26t, kneading the human body, which is similar to the pinching movement of a human hand and provides more comfortable sexual stimulation, and therefore the user is more likely to reach orgasm with the help of the sex toy 100t.

[0168] In this embodiment, the first pivot 442t is adjacent to the connecting end 444t and is distant from the swing end 443t of the swing bar 441t, so that the swing end 443t of the swing bar 441t, which rotates around the first pivot 442t, can achieve a larger swing amplitude even if the swing angle of the swing bar 441t, which rotates around the second pivot 481t, is small. As a result, the first massage part 24t driven by the swing bar 441t can provide an enhanced stimulation to the human body.

[0169] 52 and 53, the control circuit board 82 is attached to the shell 20t and electrically connected to the rotation motor 421t and the vibration motor of the second stimulation module 50t. The control circuit board 82 controls the operation of the rotation motor 421t and the vibration motor of the second stimulation module 50t, for example, by controlling the vibration frequency of the vibration motor of the second stimulation module 50t and the rotation speed of the rotation motor 42t, in accordance with user instructions. The control button 84t may be a mechanical button, a touch button, or the like, and may be provided on the shell 20t for inputting user instructions. The battery 80t, preferably a secondary battery, is disposed within the main body 22t of the shell 20t and electrically connected to the rotation motor 421t, the vibration motor, and other electrical components of the second stimulation module 50t, supplying power to them via the control circuit board 82t.

[0170] During operation, the first stimulation module 40t may be activated separately to achieve a stimulation effect on the human body, such as the breasts, through the vibration of the first massage portion 24t. Alternatively, the second stimulation module 50t may be activated separately to generate a stimulation effect on the human body through the high-frequency vibration of the second massage portion 26t. Alternatively, the first and second stimulation modules 40t, 50t may be activated simultaneously to provide multi-stimulation effects to the human body. To enhance user comfort, the first massage portion 24t and the second massage portion 26t of the shell portion 20t are configured as a soft single-layer structure, i.e., without a hard inner shell 24t.

[0171] In the above-described sex toy 100t, a chamber 28t is formed between several first massage units 24t to accommodate a part of the human body, such as a breast. The first massage units 24t swing toward or away from the second stimulation module 50t, sandwiching the part of the human body within the chamber 28t. This is more suitable for stimulating women, particularly their breasts. While breast stimulation may not enhance the sexual experience during sexual intercourse, it also plays a role in the treatment of breast disorders in healthcare. Furthermore, such a sex toy may also be used by men to stimulate the glans penis.

[0172] Furthermore, it should be noted that the massaging portions of the sex toy are not limited to being shaped like petals as in the previous embodiment. In other embodiments, the massaging portions may be shaped like fingers, claws, etc. A sex toy 100' provided in a twelfth embodiment of the present application is shown in Figure 58. The massaging portions 26' of the shell portion 20' are shaped like fingers and are arranged around the vibrating portion 24'. In this case, the gap 29' between adjacent massaging portions 26' is much wider.

[0173] Furthermore, the massaging portions are not limited to being separated from each other. A sex toy 100'' provided in a thirteenth embodiment of the present application is shown in Figure 59. Several massaging portions 26'' are arranged around a vibrating portion 24b'', and a connecting portion 27'' is formed between two adjacent massaging portions 26'' of the shell portion 20''. Preferably, the connecting portion 27'' is flexible and curved, which does not affect the rocking motion of the massaging portions 26''.

[0174] When the massage portion 26'' covers the breast during use, a sealed space of negative pressure may be formed between the massage portion 26'' and the human body, which further enhances the stimulating effect of the sex toy 100''. To improve flexibility and reliability, the connecting portion 27'' is integrally formed with the massage portion 26'' by soft silicone, and the thickness of the connecting portion 27'' is much smaller than the thickness of the massage portion 26''.

[0175] 60 to 70 show a sex toy according to a fourteenth embodiment of the present application. In this embodiment, the sex toy 100p comprises a shell 20p and a stimulation assembly mounted within the shell 20p.

[0176] 60, the shell portion 20p includes a main body portion 22p, a second massage portion 26p, and a plurality of first massage portions 24p arranged around the second massage portion 26p. As in the first embodiment, the main body portion 22p of the shell portion 20p is configured with two layers, i.e., an inner hard layer and an outer soft layer, while the second massage portions 26p and the first massage portions 24p are configured with a single layer. Preferably, the second massage portions 26p and the first massage portions 24p are formed integrally with the outer soft layer of the main body portion 22p.

[0177] The second massage portion 26p is generally cylindrical with a dome-shaped tip, and each first massage portion 24p is curved and sheet-like. In this embodiment, adjacent first massage portions 24p are connected to each other, so that the chambers 28p formed between the first massage portions 24p are generally circumferentially surrounded, thereby better enveloping the user's breasts during use. Preferably, the connection between two adjacent first massage portions 24p is generally V-shaped, which facilitates rocking of the first massage portions 24p.

[0178] Referring to Figures 62 to 66, the stimulation assembly is provided inside the second massage portion 26p of the shell portion 20p and includes a third stimulation module 30p such as a vibration motor for driving the second massage portion 26p to vibrate, a second stimulation module 40p for driving the first massage portion 24p to swing it toward or away from the second massage portion 26p, and a third stimulation module 50p for driving the first massage portion 24p to rotate it.

[0179] 67 to 68, the first stimulation module 40p includes a gearbox 42p, a swing unit 44p, and a first transmission unit 46p coupled between the gearbox 42p and the swing unit 44p.

[0180] The first transmission unit 46p is configured to convert the rotation of the output shaft 429 of the gearbox 42p into reciprocating linear motion. As shown in Fig. 67, the first transmission unit 46p includes a fixed member 72p, a rotating member 74p, and a sliding member 76p that cooperate with each other, where the rotating member 74p is connected to the output shaft 429p of the gearbox 42p in a transmission manner. Preferably, a steering gear unit 43p is provided between the output shaft 429p and the rotating member 74p to change the direction of power transmission, which facilitates the arrangement of the gearbox 42p.

[0181] The steering gear unit 43p may be composed of two bevel gears to achieve a 90-degree change in the power transmission direction. As shown in FIG. 67, the gearbox 42p is disposed so that its output shaft 429p extends along the X direction, while the output shaft 431p of the steering gear unit 43p extends along the Z direction. In other embodiments, the output shaft 431p of the steering gear unit 43p may be inclined relative to the output shaft 429p of the gearbox 42p. In other embodiments, the rotating member 74p may be directly coupled to the output shaft 429p of the gearbox 42p, thereby eliminating the need for the steering gear unit 43p.

[0182] The fixed member 72p is fixedly mounted within the shell portion 20p, and a first sliding groove 721p extending along the Z direction is defined within the fixed member 72p. The rotating member 74p is rotatably mounted within the shell portion 20p, and a second sliding groove 741p extending spirally in the circumferential direction is defined within the rotating member 74p. The sliding member 76p cooperates with the first sliding groove 721p and the second sliding groove 741p to convert rotation of the rotating member 74p into reciprocating linear motion of the sliding member 76p in the Z direction.

[0183] In this embodiment, the interior of the shell portion 20p, particularly the interior of the inner shell 201p, is provided with a mounting seat 78p for accommodating the steering gear unit 43p, the fixed member 72p, the rotating member 74p, and the sliding member 76p therein. Two locking holes 781p are formed in the mounting seat 78p, and two locking tabs 723p extending radially and outwardly from the fixed member 72p engage with the locking holes 781p, respectively, thereby fixedly connecting the fixed member 72p to the mounting seat 78p. In other embodiments, the locking tabs may be provided on the mounting seat 78p, and the locking holes may be limited to the fixed member 72p.

[0184] The fixed member 72p is hollow and cylindrical, the rotating member 74p is configured as a rotating shaft and is rotatably attached inside the fixed member 72p, and the sliding member 76p is configured as a hollow sleeve and is slidably attached around the fixed member 72p. In this embodiment, the output shaft 431p of the steering gear unit 43p extends inside the fixed member 72p and is connected to an end (such as the lower end) of the rotating member 74p. The rotating member 74p and the output shaft 431p may also be fixed in the circumferential direction by form-fitting, snap-fitting, or the like. During operation, the rotating member 74p is driven to rotate together with the output shaft 431p around a rotation axis extending along the Z direction.

[0185] 63, 68, and 69, the first sliding portion 761p protrudes inward and radially from the sliding member 76p and is slidably engaged with the first sliding groove 721p, and the second sliding portion 763p protrudes inward and radially from the first sliding portion 761p and is slidably engaged with the second sliding portion 741p. The first sliding groove 721p extends radially through the peripheral wall of the fixed member 72p, thereby allowing the second sliding portion 763p to extend through the first sliding groove 721p into the second sliding groove 741p. Preferably, the second sliding groove 741p is axially symmetrical with respect to the rotation axis of the rotating member 74p.

[0186] During operation, the rotating member 74p is driven to rotate about its rotation axis (i.e., the central axis of the rotating member 74p), and the second sliding portion 763p engaged with the second sliding groove 741p of the rotating member 74p tends to rotate the sliding member 76p about the rotation axis. However, the first sliding portion 761p engaged with the first sliding groove 721p of the fixed member 72p prevents the sliding member 76p from rotating. Therefore, the first sliding portion 761p slides along the first sliding groove 721p, and the second sliding portion 763p slides along the second sliding groove 741p, moving the sliding member 76p up and down in the Z direction.

[0187] In this embodiment, the first sliding portion 761p and the second sliding portion 763p are formed separately and then assembled onto the sliding member 76p, which facilitates assembly of the fixed member 72p, the rotating member 74p, and the sliding member 76p. In other embodiments, the first sliding portion 761p and / or the second sliding portion 763p may be formed integrally with the sliding member 76p, or the first sliding portion 761p and the second sliding portion 763p may be formed integrally as one piece.

[0188] The swing unit 44p includes a plurality of swing bars 441p, each rotatably connected to a fixed frame 448p by a plurality of pivots 442p, where the fixed frame 448p is fixed inside the inner shell 201p. In this embodiment, the swing bar 441p is generally sheet-shaped and elongated. One end of the swing bar 441p, preferably the end farther from the first pivot 442p, is configured as a swing end 443p and extends into one of the first massage sections 24p of the shell 20p. The other end of the swing bar 441p, preferably the end adjacent to the first pivot 442p, is configured as a connecting end 444p that is connected to the sliding member 76p.

[0189] In this embodiment, an opening 449p is defined in the center of the fixed frame 448p, the first and second sliding portions 761p and 763p are provided at one end (such as the lower end) of the sliding member 76p, and the other end (such as the upper end) of the sliding member 76p extends into the opening 449p of the fixed frame 448p. Referring to Fig. 65, a plurality of linear grooves 765p are defined in the outer peripheral wall at the upper end of the sliding member 76p, and the connecting ends 444p of the swing bar 441p are rotatably engaged with the linear grooves 765p, respectively.

[0190] In operation, the sliding member 76p is driven by the gearbox 42p to move in the Z direction, which in turn drives the connecting end 444p of the oscillating bar 441p to move in the Z direction at the same time, the connecting end 444p therefore rotates in the linear groove 765p, and therefore the whole oscillating bar 441p rotates around the first pivot 442p, and finally the oscillating end 443p and the first massage part 24p, with the oscillating end 443p inserted therein, oscillate or rock against each other, so as to knead the human body in the chamber 28p, which is similar to the pinching movement of a human hand and provides more comfortable sexual stimulation.

[0191] 67 and 68, the second stimulation module 50p includes a drive rod 52p, a rotating part 54p, and driving parts such as a rotation motor and gear components.

[0192] The driving rod 52p has a first end 521p having a first central axis X1 and a second end 523p having a second central axis X2. The first central axis X1 extends along the Z direction, and the second central axis X2 is inclined relative to the first central axis X1. An obtuse angle α is preferably defined between the first central axis X1 and the second central axis X2. The first end 521p is connected to the driving component in a transmission manner, and the second end 523p is engaged with the rotating component 54p. Preferably, a flange 525p is formed at the tip of the second end 525p to prevent the second end 525p from coming off the rotating component 54p.

[0193] In this embodiment, the rotating element 54p is configured as a rigid hollow structure, and the third stimulation module 30p is housed within the rotating element 54p. As shown in FIG. 63, the second massage element 26p defines a cavity 241p therein, within which the rotating element 54p and the third stimulation module 30p are fixed. Preferably, the central axis of the second massage element 26p is collinear with the second central axis X2 of the second end portion 523p and inclined relative to the first central axis X1 of the first end portion 521p. During operation, the first end portion 521p of the drive rod 52p is driven to rotate about the first central axis X1, thereby rotating the second end portion 523p of the drive rod 52p about the first central axis X1, which in turn drives the vibration motors of the second massage element 26p and the third stimulation module 30p to rotate about the first axis X1.

[0194] 63 to 67, the first end 521p of the drive rod 52p is connected to the output shaft 429p of the gearbox 42p via the rotating member 74p. That is, the gearbox 42p also functions as a driving component of the second stimulation module 50p. Specifically, the first end 521p of the drive rod 52p extends into the sliding member 76p, defining an axial hole 527p therein. The connecting rod 743p extends from the other end (such as the upper end) of the rotating member 74p through the fixed member 72p to the sliding member 76p. The connecting rod 743p is inserted into the axial hole 527p to connect the drive rod 52p to the rotating member 74p.

[0195] In other embodiments, the drive rod 52p may be coupled to the output shaft 429p of the gearbox 42p in other ways, such as by a shaft coupling device. Alternatively, the drive rod 52p may be directly coupled to the output shaft 429p of the gearbox 42p. In other embodiments, a separate gearbox may be provided to rotate the drive rod 52p, and as a result, the rotation of the second massage unit 26p may be controlled separately. In this embodiment, the second massage unit 26p not only stimulates the breasts through high-frequency vibrations generated by the third stimulation module 30p, but also kneads the breasts through rotation generated by the second stimulation module 50p, thereby further enhancing the stimulation effect.

[0196] In another embodiment, to further improve the stimulating effect of the first massage parts 24p, another vibration motor 27p may be provided inside one, some, or all of the first massage parts 24p, as shown in Fig. 62. Preferably, the vibration motor 27p is provided adjacent to the outer end of the first massage part 24p, preferably adjacent to the swing end 443p of the swing bar 441p, so that vibrations can be transmitted to the human body more efficiently.

[0197] 71 to 74 show a sex toy according to a fifteenth embodiment of the present application. In this embodiment, the sex toy 100q comprises a shell 20q and a stimulation assembly mounted within the shell 20q.

[0198] The shell portion 20q includes a main body portion 22q, a second massage portion 26q, and two first massage portions 24q. The second massage portion 26q is configured as a tongue, and the first massage portions 24q are arranged on two opposing sides of the second massage portion 26q. A chamber 28q is defined between the first massage portion 24q, and the second massage portion 26q extends partially beyond the chamber 28q. In this embodiment, the two first massage portions 24q are connected to each other in the circumferential direction and are configured as a mouth as a whole. Preferably, the connection between the two first massage portions 24q is roughly V-shaped.

[0199] As shown in FIG. 73, in this embodiment, the stimulation assembly is provided inside the second massage portion 26q of the shell portion 20q and includes a third stimulation module 30q such as a vibration motor for driving the second massage portion 26q to vibrate, a second stimulation module 40q for driving the first massage portion 24q to swing it toward or away from the second massage portion 26q, and a third stimulation module 50q for driving the first massage portion 24c to swing it.

[0200] As shown in FIG. 74, the first stimulation module 40q includes a gearbox 42q, a swing unit 44q, and a first transmission unit 46q connected between the gearbox 42q and the swing unit 44q for converting the rotation of the gearbox 42q into reciprocating linear motion.

[0201] The transmission unit 46q includes a fixed member 72q defining a first sliding groove 721q therein, a rotating member 74q defining a second sliding groove 741q therein, and a sliding member 76q having a first sliding portion 761q slidably engaged with the first sliding groove 721q and a second sliding portion 763q slidably engaged with the second sliding groove 741q (see FIG. 72). The first sliding groove 721q of the fixed member 72q is elongated in the Z direction, and the second sliding groove 741q of the rotating member 74q extends spirally in the circumferential direction.

[0202] In this embodiment, the through-hole 729q is limited to an end (e.g., the lower end) of the fixed member 72q, and a fixing member such as a screw extends through the through-hole 729q to fix the fixed member 72q to the shell portion 20q, and then to the gear housing 425q of the gearbox 42q. The rotating member 74q is configured as a rotating shaft, rotatably attached to the fixed member 72q, and is coupled to the output shaft 429q of the gearbox 42q in a transmission manner. The sliding member 76q is configured as a hollow sleeve, and is attached to the periphery of the fixed member 72q. Two connecting rods 769q extend radially and outward from the sliding member 76q.

[0203] The swinging unit 44q includes two swinging bars 441q, each located on two opposing sides of the sliding member 76q. Each swinging bar 441q is rotatably connected to the shell 20q, particularly the inner shell 201q, by a first pivot 442q, which is parallel to the connecting rod 769q. One end of each swinging bar 441q remote from the first pivot 442q is configured as a swinging end 443q and extends to one of the first massage sections 24q of the shell 20q. The other end of each swinging bar 441q adjacent to the first pivot 442q is configured as a connecting end 444q that connects the swinging bar 441q to the sliding member 76q.

[0204] In this embodiment, the connecting end 444q of each swing bar 441q defines an elongated slot 445q therein. Each connecting rod 769q is movably and rotatably engaged with the elongated slot 445q of a corresponding swing bar 441q, so that the sliding member 76q drives the connecting end 444q of the swing bar 441q to synchronously reciprocate in the Z direction, thereby driving the swing bar 441q to rotate the corresponding first pivot 442q in opposite directions. Finally, the swing end 443q and the first massage portion 24q swing toward or away from the second massage portion 26q.

[0205] As shown in FIG. 74, the second stimulation module 50q includes a drive rod 56q, a swinging element 58q, and drive elements such as a rotary motor and a gearbox. The drive rod 56q is connected to the drive elements via a transmission system and driven to rotate about a rotation axis extending along the Z direction. An eccentric rod 562q is eccentrically set on the drive rod 56q and extends toward the sliding element 58q. The swinging element 58q defines a long groove 581q for accommodating the eccentric rod 562q, and the long groove 581q extends in a direction perpendicular to the rotation axis of the drive rod 56q (e.g., the Y direction).

[0206] The oscillating part 58q is rotatably coupled to the shell part 20q by a third pivot 583q, where the third pivot 583q extends along the Y direction and is spaced apart parallel to the elongated groove 581q. In operation, the eccentric rod 562q is driven to rotate about the rotation axis of the drive rod 56q, and displacement in the Y direction causes the eccentric rod 562q to slide relative to the oscillating part 58q along the elongated groove 581q, while displacement in the X direction causes the oscillating part 58q to move therewith in the X direction, thereby causing the oscillating part 58q and the second massage part 26q to oscillate about the third pivot 583q in the XZ plane.

[0207] As shown in FIG. 72, the second massage part 26q defines a cavity 261q for accommodating the oscillating part 58q therein. Preferably, two support arms 203q extend from the inner shell 201q into the cavity 261q to respectively support two ends of the third pivot 583q. Preferably, the oscillating part 58q has an upper part embedded in the second massage part 26q and a lower part provided with the third pivot 583q and an elongated groove 581q housed in the cavity 261q. The drive rod 56q extends into the cavity 261q, and the eccentric rod 562q is slidably inserted into the elongated groove 581q of the oscillating part 58q.

[0208] Preferably, the oscillating element 58q is made of a hard material, and the third stimulation module 30q is attached to the oscillating element 58q, so that the oscillating element 58q and the second massage part 26q can oscillate together. Therefore, the second massage part 26q not only stimulates the human body through the high-frequency vibrations of the third stimulation module 30q, but also kneads the human body through the oscillations of the second stimulation module 50q, thereby further enhancing the stimulating effect of the second massage part 26q.

[0209] In this embodiment, the drive rod 56q is integrally formed on the upper end of the rotating member 74q, and the gearbox 42q also functions as a drive component of the second stimulation module 50q. In other embodiments, the drive rod 56q may be formed separately and then directly or indirectly connected to the gearbox 42q. In other embodiments, a separate gearbox is provided to rotate the drive rod 56q, thereby separately controlling the swinging motion of the second massage portion 26q.

[0210] Finally, it should be noted that the above describes only the preferred embodiments of the present application, and is not intended to define the scope of the present application. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art may find that the technical aspects described in the above embodiments may be modified, or some technical features may be replaced with equivalents. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should fall within the scope of the present application.
