The terms used in the description of this application are intended to explain specific embodiments only and are not intended to limit this application.Referring to Figs. 1 to 5, there is shown a sexual stimulation apparatus 100 according to a first embodiment of the present application. The sexual stimulation apparatus 100 comprises a housing 10 and a drive mechanism 20 disposed in the housing 10. The drive mechanism 20 is power-transmittingly connected to the massage portion 11. Under the action of the drive mechanism 20, the massage section 11 rotates about a first axis X 1 to generate an annular trajectory. A sensitive area of the human body such as the clitoris or vagina of a user or the end intestine or prostate of a user can be stimulated by the massage section 11 as long as it lies in the annular trajectory of the massage section 11.The massage portion 11 which is in direct contact with the human body as a functional part of the present sexual stimulation apparatus is flexible and may be made of silicone, rubber and the like. The massage portion 11 has a soft haptic feel and can provide a certain cushioning effect, thereby improving convenience of use. Note that the massage portion 11 may be made of another soft material that is allowed to directly contact the human body, but the present application is not limited thereto. In contrast to the conventional sexual stimulation apparatus which stimulates the human body only by the impact at a high frequency, the massage portion 11 of the present sexual stimulation apparatus rotates to generate an annular trajectory and thereby kneads the sensitive area of the human body. The area of the human body kneaded by the massage portion 11 is enlarged, and thus a better stimulating effect is obtained. Moreover, the massage portion 11 kneads the human body similarly to a human hand, providing a more comfortable user experience.In this embodiment, the housing 10 further includes a handle end. The massage portion 11 is defined at a front end of the housing 10, and the grip end is defined at a rear end of the housing 10, thereby promoting grip of the housing 10. In this embodiment, the massage portion 11 is formed substantially in a spherical or ellipsoidal shape.As shown in FIGS. 1 and 2, the housing 10 is elongated and substantially rod-shaped, i.e., similar to a male penis. In use, the housing 10, particularly the massage portion 11 of the housing 10, is inserted into the sexual organ of the human body such as the vagina, the colon and the like. It is to be understood that the sexual stimulation apparatus 100 of the present application is not limited to use in a human body. In some embodiments, sexual stimulation device 100 may be used to stimulate the breast of a human body. According to the specific application scenario, the housing 10 may be configured in different shapes such that the massage portion 11 of the housing more easily contacts the sexual organ of the user.In this embodiment, a front end of the housing 10 is bent laterally, and a base portion 52 is formed at the front end of the housing 10. One end of the massage portion 11 serving as a connection end is connected to the base portion 52, and the other end of the massage portion 11 serves as a free end. Specifically, the base portion 52 is concaved inwardly to form a cup-shaped portion arranged around the first axis X 1. Here, the first axis X 1 is substantially perpendicular to the longitudinal direction of the housing 10, and the massage portion 11 is mounted in the base portion 52, one end of which serves as a connection end for connection to a central bottom part of the base portion 52. The massage portion 11 partially extends beyond the base portion 52 through an open side 521 of the base portion 52, and when the massage portion 11 is rotated, it pivots in the base portion 52 using the connection end of the massage portion as a center. It is to be understood that the base portion 52 may be formed in another shape, such as a protrusion or a column having the same height as that of the handle end.In this embodiment, the package 10 may be a dual layer structure comprising an outer layer 10a and an inner layer 10b within the outer layer 10a. The outer layer 10a is made of a soft material and the inner layer 10b is made of a hard material such as plastic, metal, etc. The inner layer 10b provides support for the outer layer 10a and the drive mechanism 20. In this embodiment, the massage portion 11 may be a single-layer structure including the outer layer 10 a.In this embodiment, the outer layer 10 aof the massage portion 11, the outer layer 10 aof the base portion 52, and the outer layer 10 aof the remaining case 10 are integrally formed, which not only facilitates production and assembly of the sexual stimulation device 100, but also improves the strength of connection between the massage portion 11 and the outer layer 10 a. When the massage portion 11 rotates about the first axis X 1, there may be greater deformation without damage, thereby increasing the force and the margin of stimulation of the massage portion 11 on the human body. Moreover, the outer layer 10a closes the inner layer 10b, so that it can achieve good sealing for the components inside the housing 10, plays a role for water sealing and dust sealing, thus promoting keeping clean and storage of the sexual stimulation device 100. It is to be understood that in the sexual stimulation apparatus 100 of the present application, the massage portion 11 and the outer layer 10a of the housing 10 may be separately formed and then joined together so that the massage portion 11 can be disassembled and replaced selectively. In practical applications, the sexual stimulation device 100 may be formed with some massage portions 11 of different shapes and / or sizes. According to the specific use scenarios, the user or the user can select a corresponding massage section 11 in order to ensure the stimulation effect. In this case, it is no longer limited to the outer layer 10 abeing formed of the same material as that of the massage portion 11. Both a soft material such as silicone and rubber and a hard material such as plastic and alloy can be used for forming the outer layer 10a.Referring to FIGS. 5 and 6, the drive mechanism 20 includes a drive module 22 and a first drive rod 24. the drive mechanism 20 is connected to the first drive rod 24 to rotate the first drive rod 24 about the first axis X 1. The first drive rod 24 includes a first end 24 aand a second end 24 b. The second end 24 bis inclined relative to the first end 24 a. The first end 24a is connected to the drive module 22, and the second end 24b is inserted into and connected to the massage portion 11. A first vibration component 41 such as a vibration motor is provided inside the massage portion 11. When the massage portion 11 is rotated, it may vibrate together with the first vibration component 41 at a predetermined frequency which not only stimulates the sensitive area of the human body by kneading but also generates deep stimulation by vibrations. The combination of stimulations of both types makes the stimulated region of the human body, such as a sexual organ, e.g., clitoris and prostate more excited, so that the user / user is more likely to get an orgasm by means of the present sexual stimulation apparatus 100, resulting in better sex life and sexual experience.In this embodiment, a first angle α1is defined between the second end 24 band the first end 24 a. The first end 24 aof the first drive rod 24 extends along the first axis X 1 and the second end 24 bextends along a first central axis X 3. A second angle β 1 is defined between the first central axis X 3 and the first axis X 1. Preferably, the second angle β1is an obtuse angle, and more preferably, the second angle β1is less than 45°. The first angle α 1 between the first end 24 aand the second end 24 bis complementary to the second angle β 1 between the first axis X 1 and the first central axis X 3. That is to say, the sum of the first angle α1and the second angle β1is 180°, that is to say α1+β1=180°. In this way, the second angle β 1 between the first center axis X 3 and the first axis X 1 can be determined according to the first angle α 1 between the first end 24 aand the second end 24 bof the first drive rod 24 to set the rotation radius of the massage portion 11. In this embodiment, the massage portion 11 is substantially coaxial with the second end 24 bof the first drive rod 24, i.e., the first center axis X 3 is a center axis of the massage portion 11.As shown in FIG. 6, the drive module 22 includes a motor module 221, a first gear 223, and a second gear 224. The first gear 223 is connected to an output shaft 2211 of the motor module 221. The second gear 224 and the third gear 223 are meshed with each other. The first end 24 aof the first drive rod 24 is connected to the second gear 224. The motor module 221 may be a DC motor and includes the output shaft 2211 rotating at a high speed. The motor module 221 is operated to rotate the first gear 223 and the second gear 224 and in turn rotate the first drive rod 24, thereby rotating the massage portion 11 about the first axis X 1. In a specific embodiment, the first gear 223 and the second gear 224 are bevel gears so that a rotation axis of the first drive rod 24 and a rotation axis of the output shaft 2211 of the motor module 221 intersect (the rotation axes intersect perpendicularly in the embodiment shown in FIG. 2 ), thus promoting the arrangement of the drive module 22 to minimize the sexual stimulation device 100. It is understood that the first gear 223 and the second gear 224 may be replaced with other transmission mechanisms such as cylindrical gears, worm, and worm gears. Moreover, a transmission module (such as one or more gears) may be located between the first gear 223 and the second gear 224.In this embodiment, the massage portion 11 is disposed at the front end of the housing 10, and the drive mechanism 20 is mounted adjacent to the front end of the housing 10 to improve the connection between the drive mechanism 20 and the massage portion 11. The first gear 223 and the second gear 224 function as a steering unit between the drive module 22 and the first drive rod 24 to facilitate the arrangement of the drive module 22.In a specific embodiment, the motor module 221 includes a motor and a gear unit connected between the first gear 223 and the motor. The reduction ratio of the gear unit is not less than 4:1 and not more than 100:1, and the output speed of the motor module 221 does not exceed 1000 rpm. Thus, the speed of the output shaft 2211 of the motor module 221 does not exceed 1000 rpm. Accordingly, the speed of the first drive rod 24 and / or the massage portion 11 does not exceed 1000 rpm. In some embodiments, the motor module 221 may be directly connected to the first drive rod 24 and the first gear 223 and the second gear 224 may be omitted. Here, the output shaft 2211 of the motor module 221 may be inclined or perpendicular to the output shaft of the motor. In this case, the transmission unit may include bevel gears and the like, and the drive module 22 itself may realize the power transmission and change the direction of the power transmission.In a specific embodiment, the vibration component 41 may be integrally fixed inside the massage portion 11 during the formation of the massage portion 11.As shown in FIG. 3, along the first axis X 1, the depth of the base portion 52 is less than the height of the massage portion 11, so that the massage portion 11 partially extends beyond the base portion 52 through the open side 521 to facilitate contact with the human body. The first vibration component 41 is fixed in a part of the massage portion 11 extending beyond the base portion 52 so that the first vibration component 41 can be located closer to the human body. The first central axis X 3 of the massage portion 11 is coaxial with or parallel to the central axis of the second end 24 b, and the central axis of the base portion 52 is coaxial with or parallel to the central axis of the first end 24 a, so that the massage portion 11 is disposed eccentrically relative to the base portion 52 to promote the vibration of the massage portion 11 within the base portion 52. In the pivoting of the massage portion 11, a central portion thereof is located adjacent to an inner edge of the open side 521 of the base portion 52.In practical use, the stimulated part of the human body could be slightly recessed under the action of the massage portion 11. Accordingly, due to the recessed stimulated portion, a part of the human body around the stimulated portion may protrude. The base portion 52 further supports and surrounds the vicinity of the stimulated part. The massage portion 11 protrudes outwards relative to the base portion 52 to allow to maintain its contact with the recessed stimulated part, thus allowing a further enhancement of the stimulating effect. In some embodiments, the depth H of the base portion 52 is 5-10 mm, such as 6.5 mm, 7.8 mm, etc. The diameter D of the open side 521 of the base portion 52 is 20-50 mm, such as 32 mm, 45 mm, etc. The height L by which the massage portion 11 extends beyond the open side 521 of the base portion 52 is less than 50 mm, such as 18.5 mm, 35 mm, etc.Under the driving of the driving module 22, the first driving rod 24 drives the massage section 11 in rotation about the first axis X 1 at a suitable speed, which does not exceed 1000 rpm, for example. The first end 24 aof the first drive rod 24 rotates about its central axis, i.e. the first axis X 1. The second end 24 band the massage portion 11 connected to the second end 24 brotate about the first axis X 1 and the first end 24 a, respectively. The trajectory of the massage portion 11 about the first axis X 1 is substantially circular, and the region of the human body covered by this circular trajectory may be kneaded by the massage portion 11, which increases the region of stimulation and improves the stimulation effect.As shown in FIG. 7, the projection of the massage portion 11 onto a plane perpendicular to the first axis X 1 substantially represents a circle having a radius of R 1, and the projection of the open side 521 of the base portion 52 substantially represents a circle having a radius of R 2. In this case, the centers of the two projected circles are spaced apart from one another at a specific distance. When the massage portion 11 rotates about the first axis X 1, the base portion 52 may assist the rotation of the massage portion 11 and limit the rotation trajectory of the massage portion 11. In the present application, the massage portion 11 rotates about the first axis X 1, and its trajectory substantially represents a circle having a radius of R 3, where R 3 is larger than R 1, that is, R 3>R 1.In conventional devices, the human body is generally stimulated by striking at a high frequency. In the same massage section 11, the stimulated area of a conventional device essentially represents a circle with a radius of R1, while the stimulated area of the device according to the invention essentially represents a circle with a radius of R3. Therefore, an increased range of stimulation on the human body can be obtained by changing the moving manner of the massage portion 11 without changing the size of the massage portion 11, achieving a better stimulating effect. It is to be understood that depending on the sexual organ to be stimulated, the massage portion 11 may have a different size and / or the massage portion 11 may be kinked by a different angle relative to the base portion 52 to further improve the range of stimulation of the massage portion 11 on the human body.In an embodiment shown in FIG. 8, the second angle α 1 between the first center axis X 3 of the massage portion 11 and the first axis X 1 is increased while the sizes of the base portion 52 and the massage portion 11 are maintained. The distance between the center of the projection of the massage section 11 onto the plane perpendicular to the first axis X 1 and the first axis X 1 is increased. Thus, the turning radius of the massage portion 11 is increased up to R 4. In this way, the trajectory of the massage section 11 essentially represents a circle with a radius of R4, wherein R4is greater than R3, i.e. R4>R3. Because of the quadratic relationship between the area and the radius, a slight increase in the radius of rotation of the massage portion 11 may result in a huge increase in the range of stimulation, further enhancing the stimulating effect.In this embodiment, a first drive gear 26 is mounted around the second end 24 bof the first drive rod 24. Generally, the first driving wheel 26 is formed in a flat and annular shape, and has a radial dimension larger than that of the first driving rod 24, so that it can more easily rotate the massage portion 11. During production, the first drive rod 24 and the first drive wheel 26 can be pre-assembled and inserted into a forming tool. Subsequently, the massage section 11 is formed by insert molding. The first drive wheel 26 may be integrally fixed in the massage portion 11 to effectively improve the connection stability therebetween. The massage portion 11, particularly the end thereof connected to the base portion 52, may have a clearance fit with the first drive rod 24 to allow the massage portion 11 to deform sufficiently during rotation with the first drive rod 24 to achieve smoother rotation of the massage portion 11.Preferably, the first drive wheel 26 has a first neck 27. At the first neck 27, the first drive wheel 26 has the smallest inner diameter. The second end 24 bof the first drive rod 24 extends through the first neck 27 and forms two first projections 25 on two opposite axial sides of the first neck 27. The outer diameter of the protrusion 25 is larger than the inner diameter of the first neck 27, After the joining, the first protrusions 25 functions as a position limiting component for the first neck 27, so that the first driving wheel 26 is not detachable from the first driving rod 24 without an external force, which promotes the formation and production of the outer housing and the massage portion 11 in a subsequent process. Of course, the first drive gear 26 and the first drive rod 24 may be fixed to each other by another means such as a close fit, which is not limited in the application.In this embodiment, a plurality of buttons 31 are provided at the handle end, such as power button, function button, etc. In the handle end of the housing 10, a control device, such as a control board 33, is provided. The button 31 forms a control circuit including the drive module 22, the first vibration component 41, and the like through the control board 33. The user or the user can control the operation of the sexual stimulation device 100 such as the speed and rotational direction of the drive module 22, the vibration frequency of the first vibration component 41, etc. A battery 35 such as a rechargeable battery is provided in the handle of the housing 10 and electrically connected to the control board 33, and it serves as a power source of the entire sexual stimulation device 100 through the buttons 31.In use of sexual stimulation device 100, the user or the user can select different modes as needed through knobs 31 on the handle. For example, the user or the user may only turn on the first vibration component 41 to drive the massage portion 11 to perform vibration at a high frequency, thereby achieving a certain stimulation effect by vibration. Alternatively, the user or the user may only turn on the driving module 22 for rotating the massage portion 11 to generate stimulation of the human body by kneading. Alternatively, the user or the user may simultaneously turn on the first vibration component 41 and the driving module 22 to vibrate and rotate the massage portion 11 to generate a double stimulation of the human body, facilitating the use and having a good stimulating effect.Figs. 9 and 10 show a second embodiment of the sexual stimulation apparatus of the present application, which is different from the first embodiment mainly in the massage portion 11. In this embodiment, the housing 10 of the sexual stimulation device 100 is substantially elongated and rod-shaped. A branch 18 extends from the central portion of the housing 10 curvedly to an upper side of a front end of the housing 10. The massage portion 11 is connected to the base portion 52. Specifically, the base portion 52 is concaved inwardly to form a cup-shaped portion on the housing 10. The massage portion 11 is mounted in the base portion 52 and extends partially beyond the base portion 52 through its open side 521. In this embodiment, the open side 521 of the base portion 52 is inclined to the central portion of the housing 10 at a certain angle. The massage portion 11 extends beyond the base portion 52 and is near the central portion of the housing 10.The housing 10 is provided with a drive mechanism 20 comprising a drive module 22 and a first drive rod 24. The first drive rod 24 includes a first end 24 aand a second end 24 bopposing the first end 24 a. The first end 24a is connected to the drive module 22, and the second end 24b is inserted into the massage portion 11. Under the action of the drive module 22, the massage section 11 rotates together with the second end 24 bacross the first end 24 a, generating an annular trajectory with which the human body can be kneaded. Similarly, the massage portion 11 is provided with a first vibration component 41, such as a vibration motor, that enables generation of the double stimulation of the human body by the massage portion 11.In this embodiment, the front end of the housing 10 forms a massage end 13, and a second vibration component 42 such as a vibration motor is provided in the massage end 13. At the rear end of the housing 10, a grip end is formed which serves as a handle for holding the sexual stimulation device 100. The handle end is provided with knobs 31 and the like to control the operation of the drive module 22, the first vibration component 41, the second vibration component 42 and the like. In use of the sexual stimulation device 100, the massage portion 11 and the massage end 13 act on two different parts of the human body to further improve the stimulation effect. As an example, the massage end 13 may be used for stimulating vagina and the massage portion 11 may be used for stimulating clitoris. As another example, massage end 13 may be used for stimulating the forearm and massage portion 11 may be used for stimulating the prostate. In an alternative embodiment, only one of the massage portion 11 and the massage end 13 is provided with a built-in vibration component.In this embodiment, the drive mechanism 20 has a similar structure to the drive mechanism 20 in the first embodiment. The drive mechanism 20 of this embodiment will not be discussed here any more.Figs. 11 and 12 show a third embodiment of the sexual stimulation apparatus of the present application, which is different from the first embodiment mainly in the massage portion. In this embodiment, the housing 10 of the sexual stimulation device 100 is substantially elongated and rod-shaped. A central portion of the housing 10 is inwardly and laterally recessed to form the base portion 52, and the massage portion 11 is connected to the base portion 52. Specifically, the central portion of the housing 10 is concave inwardly recessed to form the base portion 52. The massage portion 11 is mounted in the base portion 52 and extends partially beyond the base portion 52 through its open side 521. The protrusions 34 are preferably disposed on an outer surface of the massage member 11 to enhance the stimulating effect of the massage member 11.The housing 10 is provided with a drive mechanism 20 comprising a drive module 22 and a first drive rod 24. The first drive rod 24 includes a first end 24 aand a second end 24 bopposing the first end 24 a. The first end 24 ais connected to the drive module 22, and the second end 24 bis connected to the massage portion 11. Under the action of the drive module 22, the massage section 11 rotates together with the second end 24 bacross the first end 24 a, generating an annular trajectory with which the human body can be kneaded.In this embodiment, the front end of the housing 10 forms a massage end 13, and a second vibration component 42 such as a vibration motor is provided in the massage end 13. A branch 18 extends curvedly from the central portion of the housing 10 to an upper side of a central portion of the housing 10, and a third vibration component 43 such as another vibration motor is provided in the branch 18. The branch 18 is located between the handle end and the base portion 52 At the rear end of the housing 10 is formed a handle end which serves as a handle for holding the sexual stimulation device 100. The handle end is provided with knobs 31 for controlling the operation of the drive module 22, the first vibration component 41, the second vibration component 42, the third vibration component 43, and the like. In operation of this sexual stimulation device, massage portion 11, massage end 13 and branch 18 may act on three different parts of the human body. For example, the massage end 13 can be used for stimulating the vagina, the massage section 11 for stimulating the clitoris limb, and the branch 18 for stimulating the oak of the clitoris, in order to further improve the stimulation effect. In an alternative embodiment, the massage portion 11, the massage end 13 or the branch 18 is provided with a built-in vibration component, or alternatively, two parts of the massage portion 11, the massage end 13 and the branch 18 are each provided with a built-in vibration component.In this embodiment, the drive mechanism 20 has a similar structure to the drive mechanism 20 in the first embodiment. The drive mechanism 20 of this embodiment will not be discussed here any more.Figures 13 to 16 show a fourth embodiment of the sexual stimulation device 100 of the present application, which differs from the third embodiment mainly by the branch 18 and the massage end 13. In this embodiment, the housing 10 of the sexual stimulation device 100 is substantially elongated and rod-shaped. In this embodiment, the branch 18 is omitted and the massage end 13 is movable along the second axis X 2. That is, in this embodiment, the housing 10 is provided with a massage portion 11 and a massage end 13. The drive mechanism 20 is power-transmittingly connected to the massage portion 11 and the massage end 13, respectively. Under the action of the drive mechanism 20, the massage section 11 rotates about a first axis X 1 to generate an annular trajectory. The massage end 13 reciprocates along a second axis X 2 to generate a reciprocating trajectory. A sensitive area of the human body such as the clitoris or vagina of a user or the end intestine or prostate of a user can be stimulated by the massage section 11 as long as it lies in the annular trajectory of the massage section 11. A sensitive area of the human body such as the vagina of a user or a user can be stimulated by the massage end 13 by the friction of the massage end 13 as long as it is located on the reciprocating trajectory of the massage end 13. In use of the sexual stimulation device 100, the massage portion 11 and the massage end 13 simultaneously act on two different parts of the human body to further improve the stimulation effect.In this embodiment, the package 10 may be almost entirely a double layer structure comprising an outer layer 10a and an inner layer 10b within the outer layer 10a.

In particular, the outer layer 10a has an end opening 103. The inner layer 10 bhas a lid 102 for closing an end of the inner layer 10 band the outer layer 10 a. In this embodiment, the outer layer 10 amay be integrally formed around the inner layer 10 bby insert molding after the inner layer 10 bis joined to the inner components.In this embodiment, the housing 10 further includes a handle end. A front end of the housing 10 forms the massage end 13, and a rear end of the housing 10 forms the grip end serving as a handle for holding the sexual stimulation device 100. The massage portion 11 is located between the grip end and the massage end 13.In particular, the housing 10 includes an extension portion 16 formed at the handle end. The extension portion 16 is formed in the shape of a scrotum. In operation of sexual stimulation device 100, the user can hold extension portion 16 in the form of a scrotum and prefer to stimulate himself, thereby improving the stimulation effect. In particular, the housing 10 comprises a terminating end 17 which is formed at the handle end. The terminating end 17 is of plate-shaped design. In particular, the terminal end 17 is a single-layer structure with the outer layer 10 a,resulting in a flexible terminal end 17. The terminating end 17 has a concave cavity 171. The extension portion 16 is adjacent to the termination end 17 and is located between the termination end 17 and the massage portion 11 In this embodiment, the control board 33 and the battery 35 are accommodated in a cavity of the extension portion 16.A central portion of the housing 10 forms a base portion 52.

The massage portion 11 is mounted in the base portion 52 and extends partially beyond the base portion 52 through its open side 521. Specifically, a through hole 109 is defined in the inner layer 10 bto allow the first drive rod 24 to extend from the inside to the outside of the inner layer 10 b.In this embodiment, the inner layer 10b of the housing 10 includes a first portion 105 corresponding to the handle end and the base portion 52 and a second portion 106 corresponding to the massage end 13. The first portion 105 and the second portion 106 are spaced apart from each other, thereby defining a gap 108 therebetween. The second portion 106 is movable relative to the first portion 105. When the second portion 106 is reciprocated, the outer layer 10 aextend along the second axis X 2 and changes the width of the gap 108 so as to allow the movement of the massage end 13 along the reciprocating trajectory. More specifically, in the first portion 105, two beams 1051 are defined on an inner side wall thereof.

The third gear 225 is engaged with the second gear 224. One end of the threaded portion 230 is connected to the third gear 225, and a threaded slot 2271 is defined at the opposite end of the threaded portion 230. The third gear 225 has a shaft connected to the threaded portion 230. The threaded portion 230 is rotatably supported by the beams 1051 of the first portion 105. The slide member 36 movably engages with the threaded slot 2271 to form a screw-nut mechanism. The motor module 221 operates to rotate the first gear 223, the second gear 224, the third gear 225, and the threaded portion 230 and in turn to linearly move the slide member 36. In this specific embodiment, the third gear 225 is a bevel gear so that a rotation axis of the threaded portion 230 and a rotation axis of the output shaft 2211 of the motor module 221 are parallel to each other (the rotation axes are coaxial in the embodiment shown in FIG. 15 ), thereby promoting the arrangement of the drive module 22 to minimize the sexual stimulation device 100. It is understood that the third gear 225 may be replaced with other transmission mechanisms such as cylindrical gears. In another embodiment, a transmission module (such as one or more gears) may be located between the second gear 224 and the third gear 225. The screw-nut mechanism may also be replaced by another transmission mechanism, such as a rack and pinion steering gear mechanism, which converts rotation into linear motion.Specifically, the sliding member 36 includes an engaging portion 361 and a pin portion 363. The engaging portion 361 is formed in an arc shape to fit exactly with the helical thread slot 2271. The pin portion 363 is inserted into the locking slot 1064 of the second portion 106, such that the slide member 36 and the second portion 106 are moved along the second axis X 2 when the threaded portion 230 is rotated.In this embodiment, the massage portion 11 and the massage end 13 are driven by the same motor module 221 to reduce the cost and reduce the space occupied by the drive mechanism 20 for minimizing the sexual stimulation device 100. It is to be understood that in other embodiments, the massage portion 11 and the massage end 13 may be driven by two motor modules.Figs. 17 to 20 show a fifth embodiment of the sexual stimulation apparatus of the present application, which is different from the fourth embodiment in particular in the massage end 13 and the grip end. The housing 10 of the sexual stimulation device 100 is substantially elongated and rod-shaped. The massage end 13 is inclined relative to the handle end. In this embodiment, the extension portion 16 and the terminal end 17 are omitted. In this embodiment, the massage end 13 is also rotatable about the second axis X 2. That is, in this embodiment, the housing 10 is provided with a massage portion 11 and a massage end 13. The drive mechanism 20 is power-transmittingly connected to the massage portion 11 and the massage end 13, respectively. Under the action of the drive mechanism 20, the massage section 11 rotates about a first axis X 1 to generate an annular trajectory. The massage end 13 rotates about a second axis X 2 to generate an annular trajectory. A sensitive area of the human body such as the clitoris or vagina of a user or the end intestine or prostate of a user can be stimulated by the massage section 11 and the massage end 13 as long as it lies in the annular trajectory of the massage section 11. In use of the sexual stimulation device 100, the massage portion 11 and the massage end 13 simultaneously act on two different parts of the human body to further improve the stimulation effect.In this embodiment, the drive mechanism 20 includes a drive module 22, a first drive rod 24, and a second drive rod 37. the motor module 22 is connected to the first drive rod 24 and the second drive rod 37, respectively, to rotate the first drive rod 24 about the first axis X 1 and rotate the second drive rod 37 about the second axis X 2. The first drive rod 24 includes a first end 24 aand a second end 24 bopposing the first end 24 a. The first end 24 ais connected to the drive module 22, and the second end 24 bis connected to the massage portion 11. The second drive rod 37 comprises a third end 37 aand a fourth end 37 bopposing the third end 37 a. The third end 37a is connected to the drive module 22, and the fourth end 37b is connected to the massage end 13. Under the action of the drive module 22, the massage section 11 rotates together with the second end 24 bacross the first end 24 a, generating an annular trajectory with which the human body can be kneaded. The massage end 13 rotates together with the fourth end 37 babove around the third end 37 a, generating an annular trajectory with which the human body can be kneaded. Specifically, the first end 24 ais connected to the second gear 224 and the third end 37 ais connected to the third gear 225. In the specific embodiment, the first axis X 1 is perpendicular to the second axis X 2. It is understood that in another embodiment, the first axis X 1 may be inclined relative to the second axis X 2.In this embodiment, a second drive gear 38 is mounted around the fourth end 37 bof the second drive rod 37. Generally, the second driving wheel 38 is flat and annular, and has a radial dimension larger than that of the second driving rod 37, so that it can more easily rotate the massage end 13. The massage end 13 forms a connecting block 132 connected to the second drive wheel 38. The link block 132 rotates when the second drive rod 37 is rotated about the second axis X 2. A receiving slot for receiving the second drive wheel 38 is defined in the connecting block 132. The connecting block 132 and the second drive gear 38 are engaged with each other through a spherical surface. Specifically, the connection block 132 may be formed on the inner layer 10 bof the housing 10. Preferably, the second drive wheel 38 has a second neck 39. At the second neck 39, the second drive wheel 38 has the smallest inner diameter. The fourth end 37 bof the second drive rod 37 extends through the second neck 39 and forms two second projections 40 on two opposite axial sides of the second neck 39. The outer diameter of the second protrusion 40 is larger than the inner diameter of the second neck 39 After the joining, the second protrusion 40 functions as a position limiting component for the second neck 39 so that the second driving wheel 38 is not detachable from the second driving rod 37 without an external force. Of course, the second drive gear 38 and the second drive rod 37 may be fixed to each other by another means such as a close fit, which is not limited in the application.In this embodiment, a third angle α 2 is defined between the fourth end 37 band the third end 37 a. The third end 37 aof the second drive rod 37 extends along the second axis X 2 and the fourth end 37 bextends along a second central axis X 4. A fourth angle β 2 is defined between the second central axis X 4 and the second axis X 2. Preferably, the fourth angle β2is an obtuse angle, and more preferably, the fourth angle β2is less than 45°. The third angle α 2 between the third end 37 aand the fourth end 37 bis complementary to the fourth angle β 2 between the second axis X 2 and the second central axis X 4. That is to say, the sum of the third angle α2and the fourth angle β2is 180°, that is to say α2+β2=1800°. In this way, the fourth angle β 2 between the second center axis X 4 and the second axis X 2 can be determined according to the third angle α 2 between the third end 37 aand the fourth end 37 bof the second drive rod 37 to set the rotation radius of the massage end 13. In this embodiment, the massage end 13 is substantially coaxial with the fourth end 37 bof the second drive rod 37, i.e., the second center axis X 4 is coaxial with a center axis of the massage end 13.Figs. 21 to 24 show a sixth embodiment of the sexual stimulation apparatus of the present application, which is different from the fifth embodiment in particular in the massage end 13 and the grip end. In this embodiment, a part of the grip end is bent to one side of the sexual stimulation device to form a handle 15 and thereby define the sexual stimulation device in an L-shape. The bent handle 15 facilitates the holding by the user. A fourth vibration component 44, such as a vibration motor, is provided within the handle 15. In this embodiment, the massage end 13 is rotatable about a third axis X 5 in a certain range, so that the massage end 13 is pivotable about the third axis X 5. In this embodiment, the housing 10 is provided with a massage portion 11 and a massage end 13. The drive mechanism 20 is power-transmittingly connected to the massage portion 11 and the massage end 13, respectively. Under the action of the drive mechanism 20, the massage section 11 rotates about a first axis X 1 to generate an annular trajectory. The massage end 13 rotates about the third axis X 5 to generate an arcuate trajectory. A sensitive area of the human body such as the clitoris or vagina of a user or the end intestine or prostate of a user can be stimulated by the massage section 11 as long as it lies in the annular trajectory of the massage section 11. A sensitive area of the human body such as the vagina of a user or the colon can be stimulated by the massage end 13 as long as it lies in the arc-shaped trajectory of the massage end 13. In use of the sexual stimulation device 100, the massage portion 11 and the massage end 13 simultaneously act on two different parts of the human body to further improve the stimulation effect. It is to be understood that the handle end further forms a support opposite the handle 15 and thus defines the sexual stimulation device in T-shape.In this embodiment, the drive mechanism 20 includes a drive module 22, a first drive rod 24, and a pivot member 53. the motor module 22 is connected to the first drive rod 24 and the pivot member 53, respectively, to rotate the first drive rod 24 about the first axis X 1 and oscillate the pivot member 53 about the third axis X 5. The first drive rod 24 includes a first end 24 aand a second end 24 bopposing the first end 24 a. The first end 24 ais connected to the drive module 22, and the second end 24 bis connected to the massage portion 11. The pivot member 53 is connected to the massage end 13.

The massage end 13 swings together with the swing member 53 to generate an arcuate trajectory with which the human body can be kneaded. In the specific embodiment, the third axis X 5 is perpendicular to a plane spanned by the second axis X 2 and the first axis X 1.

The third drive rod 54 is connected to the drive module 22. The third drive rod 54 is rotatable about the second axis X 2. The eccentric disk 55 is connected to the third drive rod 54 so as to rotate about the second axis X 2 together with the third drive rod 54. The eccentric disk 55 includes an eccentric block 551 deviating from the second axis X 2. The pivot member 53 comprises two forked blocks 531 which are spaced apart from each other and thus form an open slot 533. The eccentric block 551 is movably accommodated in the open slot 533. The width of the eccentric block 551 is smaller than the width of the open slot 533, so that the eccentric block 551 selectively contacts only one of the two forked blocks 531. The distance D 1 of the eccentric block 551 to the second axis X 2 is larger than the difference value D 2 so that the eccentric block 551 presses the swing member 53 to swing about the third axis X 5 when the eccentric block 551 rotates. Here, the difference value D 2 represents a value formed by subtracting the width of the open slot 533 from the width of the eccentric block 551. The pivot member 53 is rotatably engaged with a rotation shaft 57 disposed along the third axis X 5 such that the pivot member 53 is rotatable about the third axis X 5. In particular, the third drive rod 54 is connected to the third gearwheel 225.Specifically, the pivot member 53 further includes a first fixing block 535, and at the second portion 106 of the inner layer 10 b, a second fixing block 1063 is formed on an inner side wall thereof. The first fixing block 535 is connected to the second fixing block 1063 to connect the swing member 53 to the massage end 13.Figs. 25 and 29 show a seventh embodiment of the sexual stimulation apparatus of the present application, which is different from the fourth embodiment mainly in the driving mechanism 20. In this embodiment, the base portion 52 is located between the massage end 13 and the handle end. The massage portion 11 is connected to the base portion 52. The drive mechanism 20 is power-transmittingly connected to the massage portion 11 and is connected to one end of the base portion 52 power-transmittingly connected to the grip end. Under the action of the drive mechanism 20, the massage section 11 rotates about a first axis X 1 to generate an annular trajectory. The massage portion 11 and the massage end 13 reciprocate along a second axis X 2 to generate a reciprocating trajectory. In a specific embodiment, the first portion 105 corresponds to the handle end and the second portion 106 corresponds to the base portion 52 and the massage end 13.In this embodiment, the drive mechanism 20 includes a drive module 22, a first drive rod 24, and a slide member 36. the drive module 22 is power-transmittingly connected to the first drive rod 24 and the slide member 36, respectively, to rotate the first drive rod 24 about the first axis X 1 and to move the slide member 36 along the second axis X 2. The first drive rod 24 includes a first end 24 aand a second end 24 b. The second end 24 bis inclined relative to the first end 24 a. The first end 24a is connected to the drive module 22, and the second end 24b is inserted into and connected to the massage portion 11. The slide member 36 is connected to an end of the base portion 52 connected to the handle end. Under the action of the drive mechanism 20, the massage section 11 rotates about a first axis X 1 to generate an annular trajectory. The massage portion 11 and the massage end 13 reciprocate along the second axis X 2 together with the slide member 36 to generate a reciprocating trajectory. In this embodiment, the slide member 36 is capable of pressing the massage portion 11, the massage end 13, and the base portion 52 to reciprocate as a whole because the slide member 36 is connected to the end of the base portion 52 connected to the grip end.In particular, the drive module 22 includes a motor module 221, a first gear 223 and a second gear 224. The first gear 223 is connected to an output shaft 2211 of the motor module 221. The second gear 224 and the third gear 223 are meshed with each other. The first end 24 aof the first drive rod 24 is connected to the second gear 224. The motor module 221 is operated to rotate the first gear 223 and the second gear 224 and in turn rotate the first drive rod 24, thereby rotating the massage portion 11 about the first axis X 1. In a specific embodiment, the first gear 223 and the second gear 224 are bevel gears so that a rotation axis of the first drive rod 24 and a rotation axis of the output shaft 2211 of the motor module 221 intersect (the rotation axes intersect perpendicularly in the embodiment shown in FIG. 2 ), thus promoting the arrangement of the drive module 22 to minimize the sexual stimulation device 100. It is understood that the first gear 223 and the second gear 224 may be replaced with other transmission mechanisms such as cylindrical gears, worm, and worm gears. In addition, a transmission member (such as one or more gears) may be located between the first gear 223 connected to the output shaft 2211 and the second gear 224 connected to the first drive rod 24.In particular, the drive module 22 further includes a threaded portion 230 and a pin 228. The threaded portion 230 is connected to the output shaft 2211, and the pin 228 is fixedly connected to the slide member 36. The pin 228 movably engages a threaded slot 2271 defined in the threaded portion 230, thereby forming a screw-nut mechanism. The motor module 221 is driven to rotate the threaded portion 230 to place the pin 228 and the slide member 36 in linear motion relative to the threaded portion 230. It is understood that the screw-nut mechanism may also be replaced by another transmission mechanism, such as a rack and pinion steering gear mechanism, that converts rotation into linear motion.In this embodiment, the sliding member 36 is fixed relative to the second portion 106. Specifically, the drive module 22 further includes a rail 229 fixed relative to the first portion 105, and the rail 229 is accommodated in the slide member 36.

The pin portion 2283 is inserted into the pin hole 362 of the slide member 36 so that the slide member 36 and the second portion 106 are moved along the second axis X 2 when the pin 228 is rotated. Specifically, the slide member 36 has two separately manufactured parts, i.e., an insert block 366 and a main portion of the slide member 36 are separately manufactured from each other. In the assembling, the engaging portion 2281 is inserted into the threaded slot 2271 of the threaded portion 230, then the threaded portion 230 extends into the rail 229, and the rail 229 is inserted into the sliding member 36. Finally, the insert block 366 is connected to the main portion of the slide member 36.Referring to FIG. 26, in a retracted state of the sexual stimulation device 100, the massage portion 11 and the massage end 13 are moved toward the grip end, and thereby the gap 108 has a first width. Referring to FIG. 30, in an extended state of the sexual stimulation device 100, the massage portion 11 and the massage end 13 are moved away from the grip end, and thereby the gap 108 has a second width larger than the first width.Figs. 31 and 34 show an eighth embodiment of the sexual stimulation apparatus of the present application, which is different from the sixth embodiment mainly in the case 10. In this embodiment, the housing 10 is elongated and substantially rod-shaped, i.e., similar to a male penis, while the handle 15 in the sixth embodiment is omitted. The housing 10 of the eighth embodiment of the sexual stimulation device is similar to the housing 10 of the third embodiment of the sexual stimulation device 100. That is, in this embodiment, the housing 10 includes a massage portion 11, a massage end 13 formed at a front end of the housing 10, and a branch 18 curvedly extending from the central portion of the housing 10 to an upper side of a front end of the housing 10.

One end of the branch 18 is connected to the first engaging portion 181 and the second engaging portion 182 and is located between the first engaging portion 181 and the second engaging portion 182.In this embodiment, the driving mechanism 20 is the same as the driving mechanism 20 of the sexual stimulation apparatus in the sixth embodiment. The drive mechanism 20 thus includes a drive module 22, a first drive rod 24, and a pivot member 53. the motor module 22 is connected to the first drive rod 24 and the pivot member 53, respectively, to oscillate the first drive rod 24 about a first axis X 1 and the pivot member 53 about a third axis X 5. The first drive rod 24 includes a first end 24 aand a second end 24 bopposing the first end 24 a. The first end 24 ais connected to the drive module 22, and the second end 24 bis connected to the massage portion 11. The pivot member 53 is connected to the massage end 13. Under the action of the drive module 22, the massage section 11 rotates together with the second end 24 bacross the first end 24 a, generating an annular trajectory with which the human body can be kneaded. The massage end 13 swings together with the swing member 53 to generate an arcuate trajectory with which the human body can be kneaded. In the specific embodiment, the third axis X 5 is perpendicular to a plane spanned by the second axis X 2 and the first axis X 1. It is to be understood that in another embodiment, the third axis X 5 may be inclined relative to the plane defined by the first axis X 1 and the second axis X 2. Specifically, the drive mechanism 20 further includes a third drive rod 54 and an eccentric disk 55. The third drive rod 54 is connected to the drive module 22. The third drive rod 54 is rotatable about the second axis X 2. The eccentric disk 55 is connected to the third drive rod 54 so as to rotate about the second axis X 2 together with the third drive rod 54. The eccentric disk 55 includes an eccentric block 551 deviating from the second axis X 2. The pivot member 53 comprises two forked blocks 531 which are spaced apart from each other and thus form an open slot 533. The eccentric block 551 is movably accommodated in the open slot 533. The width of the eccentric block 551 is smaller than the width of the open slot 533, so that the eccentric block 551 selectively contacts only one of the two forked blocks 531.
