Referring to FIGS. 1-5, a sexual stimulation device 100 according to a first embodiment of the present application is shown. The sexual stimulation device 100 includes a shell 10 and a driving mechanism 20 arranged in the shell 10. The shell 10 is provided with a massage portion 11, and the driving mechanism 20 is connected to the massage portion 11 in a transmission way. Under the action of the driving mechanism 20, the massage portion 11 rotates around a first axis X1 to form an annular trajectory. A sensitive area of the human body, such as the clitoris, the vagina of the woman, the rectum, the prostate of the man, as long as it is covered by the annular trajectory of the massage portion 11, can be stimulated by the massage portion 11.

The massage portion 11, serving as a functional part of the present sexual stimulation device that directly acts on the human body, is flexible and may be made of silicone, rubber, and etc. The massage portion 11 has a soft touch and can provide a certain buffering effect, thereby improving the comfort of use. It should be noted that the massage portion 11 may be made of other soft materials that can directly contact the human body, which is not limited by the present application. Compared to the existing sexual stimulation devices which stimulate the human body by hitting in high-frequency, the massage portion 11 of the present sexual stimulation device rotates to form an annular trajectory, and thus kneads the sensitive area of the human body. An area of the human body kneaded by the massage portion 11 is enlarged and accordingly a stimulation effect is better. Moreover, the massage portion 11 kneads the human body, which is similar to the motion of the human hand, providing a more comfortable user experience.

In this embodiment, the shell 10 further includes a holding end. The massage portion 11 is defined on a front end of the shell 10, and the holding end is defined on a rear end of the shell 10 thus facilitating to grab the shell 10. In this embodiment, the massage portion 11 is generally spherical-shaped or ellipsoidal-shaped.

As shown in FIGS. 1-2, the shell 10 is elongated and generally rod-shaped, being similar to the male penis. During use, the shell 10, particularly the massage portion 11 of the shell 10, is inserted into the sexual organs of the human body, such as the vagina, the rectum and the like. It should be understood that the sexual stimulation device 100 of this application is not limited to be used in the human body. In some embodiments, the sexual stimulation device 100 may be used to stimulate the chest of the human body. According to specific application scenarios, the shell 10 may be configured with different shapes, making the massage portion 11 thereof be easily to contact the sexual organs of the user.

In this embodiment, a front end of the shell 10 is bent laterally, and a base portion 52 is formed on the front end of the shell 10. One end of the massage portion 11 serving as a connecting end is connected to the base portion 52, and another end of the massage portion 11 serving as a free end. Specifically, the base portion 52 is concaved inwardly recessed to form a bowl-shaped portion which is arranged around the first axis X1, wherein the first axis X1 is generally perpendicular to a longitudinal direction of the shell 10. The massage portion 11 is set in the base portion 52, with one end thereof serving as a connecting end for connecting a central, bottom of the base portion 52. The massage portion 11 extends partly beyond the base portion 52 through an open side 521 of the base portion 52. When the massage portion 11 is driven to rotate, it swings in the base portion 52 with its connecting end as the center. It should be understood that the base portion 52 may be other shape, such as a protrusion and a column being as high as the holding end.

In this embodiment, the shell 10 may be a double-layer structure, and includes an outer layer 10a and an inner layer 10b inside the outer layer 10a. The outer layer 10a is made of soft material, and the inner layer 10b is made of hard materials such as plastic, metal, etc. The inner layer 10b provides support for the outer layer 10a and the driving mechanism 20. In this embodiment, the massage portion 11 may be a single-layer structure, and includes the outer layer 10a.

In this embodiment, the outer layer 10a of the massage portion 11, the outer layer 10a of the base portion 52 and outer layer 10a of the rest of the shell 10 are integrally formed, thus not only simplifying production and assembly of the sexual stimulation device 100, but also improving the connection strength between the massage portion 11 and the outer layer 10a. During rotation of the massage portion 11 around the first axis X1, it can generate greater deformation without damage, further increasing the stimulation force and stimulation range of the massage portion 11 on the human body. In addition, the outer layer 10a encloses the inner layer 10b, which can achieve good sealing effect for the components inside the shell 10, thereby play a waterproof and dustproof role, and facilitating the cleaning and storage of the sexual stimulation device 100. For the sexual stimulation device 100 of the present application, it should be understood that the massage portion 11 and the outer layer 10a of shell 10 may be formed separately and then assembled together, so that the massage portion 11 can be selectively disassembled and replaced. In practical applications, the sexual stimulation device 100 can be formed with several massage portions 11 in different shapes and/or sizes. According to specific usage scenarios, the user can choose a corresponding massage portion 11 to ensure the stimulation effect. In this situation, the outer layer 10a is no longer limited to be formed by the same material as that of the massage portion 11. Soft materials such as silicone and rubber, as well as hard materials such as plastic and alloy, may be used to form the outer layer 10a.

Referring to FIGS. 5-6, the driving mechanism 20 includes a driving module 22 and a first driving rod 24. The driving mechanism 20 is connected to the first driving rod 24 to drive the first driving rod 24 to rotate around the first axis X1. The first driving rod 24 includes a first end 24a and a second end 24b, and the second end 24b is inclined relative to the first end 24a. The first end 24a is connected to the driving 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. During rotating of the massage portion 11, it can vibrate at a predetermined frequency along with the first vibration component 41, which not only stimulates the sensitive area of the human body through kneading, but also generates deep stimulation through vibration. A combination of the two different types of stimulation makes the stimulated area of the human body, such as the sexual organs, such as the clitoris or the prostate, more excited, so that the users are more likely to reach orgasm with the help of the present sexual stimulation device 100, resulting in better sexual life and better sexual experience.

In this embodiment, a first angle α1 defined between the second end 24b and the first end 24a. The first end 24a of the first driving rod 24 extends along the first axis X1, and the second end 24b extends along a first central axis X3. A second angle β1 is defined between the first central axis X3 and the first axis X1. Preferably, the second angle β1 is an obtuse angle, and more preferably, the second angle β1 is less than 45°. The first angle α1 between the first end 24a and the second end 24b is complementary with the second angle β1 between the first axis X1 and the first central axis X3. That is, a sum of the first angle α1 and the second angle β1 is 180°, i.e., α1+β1=180°. In this way, the second angle β1 between the first central axis X3 and the first axis X1 can be determined according to the first angle α1 between the first end 24a and the second end 24b of the first driving rod 24, thereby determining a rotation radius of the massage portion 11. In this embodiment, the massage portion 11 is generally coaxial with the second end 24b of the first driving rod 24, that is, the first central axis X3 is a central axis of the massage portion 11.

As shown in FIG. 6, the driving 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 first gear 223 mesh with each other, and the first end 24a of the first driving rod 24 is connected to the second gear 224. The motor module 221 may be a DC motor, and has the output shaft 2211 rotating at high-speed. The motor module 221 runs to drive the first gear 223 and the second gear 224 to rotate, and further drives the first driving rod 24 to rotate, thus driving the massage portion 11 to rotate around the first axis X1. In a specific embodiment, the first gear 223 and the second gear 224 are bevel gears, so that a rotation axis of the first driving rod 24 and a rotation axis of the output shaft 2211 of the motor module 221 intersect (the rotation axes perpendicularly intersect in the embodiment shown in FIG. 2), thus facilitating to arrange the driving module 22 to minimize the sexual stimulation device 100. It should be understood that the first gear 223 and the second gear 224 may be replaced by other transmitting mechanisms such as cylindrical gears, worm and worm wheel. Moreover, a transmitting module (such as one or more gear) may be disposed between the first gear 223 and the second gear 224.

In this embodiment, the massage portion 11 is provided at the front end of the shell 10, and the driving mechanism 20 is set adjacent to the front end of the shell 10 to facilitate the connection between the driving mechanism 20 and the massage portion 11. The first gear 223 and the second gear 224 perform as a steering unit between the driving module 22 and the first driving rod 24 for the convenience of arrangement of the driving 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 an output speed of the motor module 221 is not exceed 1000 rpm. That is, a speed of the output shaft 2211 of the motor module 221 does not exceed 1000 rpm, and accordingly, a speed of the first driving rod 24 and/or the massage portion 11 does not exceed 1000 rpm. In some embodiments, the motor module 221 may be connected to the first driving rod 24 directly, omitting the first gear 223 and the second gear 224. At this time, the output shaft 2211 of the motor module 221 may be inclined or perpendicular relative to the output shaft of the motor. In this situation, the gear unit may include bevel gears, etc., and the driving module 22 itself may achieve power transmission and change of the power transmission direction.

In a specific embodiment, the first vibrating component 41 may be integrally fixed inside the massage portion 11 during the process of forming the massage portion 11.

As shown in FIG. 3, along the first axis X1, a depth of the base portion 52 is less than the height of the massage portion 11, so that the massage portion 11 extends partially beyond the base portion 52 through the open side 521, making it be convenient to contact the human body. The first vibrating component 41 is fixed in a portion of the massage portion 11 extending beyond the base portion 52, so that the first vibrating component 41 can be closer to the human body. The first central axis X3 of the massage portion 11 is coaxial with or parallel to the central axis of the second end 24b, and the central axis of the base portion 52 is coaxial with or parallel to the central axis of the first end 24a, so that the massage portion 11 is eccentrically arranged relative to the base portion 52, facilitating swinging of the massage portion 11 inside the base portion 52. During swinging of the massage portion 11, a middle portion thereof is adjacent to the inner edge of the open side 521 of the base portion 52.

In actual use, the stimulated part of the human body may experience slight indentations under the action of massage portion 11. Correspondingly, a part of the human body around the stimulated part may protrude due to the indentations of the stimulated part. The base portion 52 further provides support and surrounding for the surrounding part of the stimulated part. The massage portion 11 protrudes outwardly relative to base portion 52 allows it to maintain contact with the indented stimulated part, further enhancing the stimulation effect. In some embodiments, the depth H of the base portion 52 is 5-10 mm, which may be 6.5 mm, 7.8 mm, and etc. The diameter D of the open side 521 of the base portion 52 is 20-50 mm, which may be 32 mm, 45 mm, and etc. The height L of the massage portion 11 extending beyond the open side 521 of the base portion 52 is less than 50 mm, which may be 18.5 mm, 35 mm, and etc.

Under the driving of the driving module 22, the first driving rod 24 drives the massage portion 11 to rotate around the first axis X1 at an appropriate speed, such as not exceeding 1000 rpm. The first end 24a of the first driving rod 24 rotates around its central axis, i.e., the first axis X1. The second end 24b and the massage portion 11 connected to the second end 24b rotate around the first axis X1/the first end 24a. The trajectory of massage portion 11 around the first axis X1 is generally circular, and the sensitive area of the human body covered by this circular trajectory can be kneaded by the massage portion 11, thereby enlarging the stimulation area and improving the stimulation effect.

As shown in FIG. 7, on a plane perpendicular to the first axis X1, a projection of the massage portion 11 is generally a circle with a radius of R1, and a projection of the open side 521 of the base portion 52 is generally a circle with a radius of R2, wherein centers of the two projected circles are spaced from each other with a certain distance. During rotation of the massage portion 11 around the first axis X1, the base portion 52 may provide a support for the rotation of the massage portion 11 and limit the rotation trajectory of the massage portion 11. In this application, the massage portion 11 rotates around the first axis X1, and its trajectory is generally a circle with a radius of R3, wherein R3 is larger than R1, i.e., R3>R1.

For the existing devices, the human body are generally stimulated by high-frequency hitting. With the same massage portion 11, a stimulated area of the existing device is generally the circle with the radius of R1, while a stimulated area of the present device is generally the circle with the radius of R3. Therefore, without changing the size of the massage portion 11, an enlarged stimulation range on the human body can be obtained by changing the motion of the massage portion 11, thereby obtaining better stimulation effect. It should be understood that, based on the sexual organs to be stimulated, the massage portion 11 may have different sizes; and/or, the massage portion 11 may be deflected at different angles relative to the base portion 52, further improving the stimulation range of the massage portion 11 on the human body.

In one embodiment, as shown in FIG. 8, the second angle αl between the first central axis X3 of the massage portion 11 and the first axis X1 is increased, and the sizes of the base portion 52 and the massage portion 11 are not changed. The distance between the center of the projection of the massage portion 11 on the plane perpendicular to the first axis X1 and the first axis X1 is increased. That is, the rotation radius of the massage portion 11 is increased to R4. In this way, the trajectory of the massage portion 11 is generally a circle with a radius of R4, wherein R4 is larger than R3, i.e., R4>R3. Due to the square relationship between area and radius, a little increase in the rotation radius of massage portion 11 may lead to a large increase in the stimulation range, further enhancing the stimulation effect.

In this embodiment, a first driving wheel 26 is mounted around the second end 24b of the first driving rod 24. Generally, the first driving wheel 26 is a flat and annular, and has a radial size larger than that of the first driving rod 24, so that it can better drive the massage portion 11 to rotate. During production, the first driving rod 24 and first driving wheel 26 may be pre-assembled and placed in the mold, and then, the massage portion 11 is formed by over-molding. The first driving wheel 26 may be fixed inside the massage portion 11 as on piece, effectively improving the connection stability therebetween. The massage portion 11, especially its end connected to the base portion 52, may have a clearance fit with the first driving rod 24, allowing the massage portion 11 to produce sufficient deformation during rotation with the first driving rod 24, making the rotation of the massage portion 11 smoother.

Preferably, the first driving wheel 26 has a first neck 27, and the first driving wheel 26 has the smallest inner diameter at the first neck 27. The second end 24b of the first driving rod 24 extends through the first neck 27 and forms two first protrusions 25 at two opposite axial sides of the first neck 27, respectively. The outer diameter of the protrusion 25 is larger than the inner diameter of the first neck 27. After assembly, the first protrusions 25 act as position limit components for the first neck 27, so that the first driving wheel 26 will not disengages from the first driving rod 24 without external force, facilitating the forming and manufacturing of the outer shell and massage portion 11 in the subsequent process. Of course, the first driving wheel 26 and the first driving rod 24 may also be fixed by other means, such as tight fitting, which is not limited in this application.

In this embodiment, and a plurality of buttons 31 are provided on the holding end, such as switch keys, function keys, etc. In the holding end of the shell 10, a control device, such as a control circuit board 33 is provided. The button 31 forms a control circuit with the driving module 22, the first vibrating component 41, and etc. through the control circuit board 33. The user can control the operation of the sexual stimulation device 100, such as adjust the speed and rotation direction of the driving module 22, adjust the vibration frequency of first vibrating component 41, etc. through the buttons 31. A battery 35, such as a rechargeable battery, is provided in the handle of the shell 10 and electrically connected to control circuit board 33, severing as the power source of the whole sexual stimulation device 100.

During the use of the sexual stimulation device 100, the users may choose different modes through the buttons 31 on the handle according to needs. For example, the users may only start the first vibrating component 41 to drive the massage portion 11 to perform high-frequency vibration, achieving a certain stimulation effect through vibration. Alternatively, the users may only start the driving module 22 to drive the massage portion 11 to rotate, producing a kneading stimulation effect on the human body. Alternatively, the users may simultaneously start the first vibrating component 41 and the driving module 22, making the massage portion 11 to vibrate and rotating, generating a dual stimulation effect on the human body, which is convenient to use and has a good stimulation effect.

FIGS. 9-10 show a second embodiment of the sexual stimulation device of the present application, which differs from the first embodiment mainly in the massage portion 11. In this embodiment, the shell 10 of the sexual stimulation device 100 is generally elongated and rod-shaped. A branch 18 extends from the middle portion of the shell 10 curvedly towards an upper side of a front end of the shell 10, and a distal end of the branch 18 forms the base portion 52. The massage portion 11 is connected to the base portion 52. Specifically, the base portion 52 is concaved inwardly recessed to from a bowl-shaped portion on the shell 10. The massage portion 11 is set in the base portion 52 and partly extends beyond the base portion 52 through its open side 521. In this embodiment, the open side 521 of the base portion 52 is inclined at a certain angle towards the middle portion of the shell 10, and the massage portion 11 extends beyond the base portion 52 is close to the middle portion of the shell 10.

The shell 10 is provided with a driving mechanism 20, which includes a driving module 22 and a first driving rod 24. The first driving rod 24 includes a first end 24a and a second end 24b opposite to the first end 24a. The first end 24a is connected to the driving module 22, and the second end 24b is inserted into the massage portion 11. Under the action of the driving module 22, the massage portion 11 rotates along with the second end 24b around the first end 24a, forming an annular trajectory, which can generate a kneading effect on the human body. Similarly, the massage portion 11 is provided with a first vibrating component 41, such as a vibration motor, which allows the massage portion 11 to generate dual stimulation on the human body.

In this embodiment, the front end of the shell 10 forms a massage end 13, and a second vibrating component 42, such as a vibration motor, is provided inside the massage end 13. A holding end is formed on the rear end of shell 10 serving as a handle for holding of the sexual stimulation device 100. The holding end is equipped with buttons 31, etc., to control the operation of driving module 22, the first vibrating component 41 and the second vibrating component 42 etc. During 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, further improving the stimulation effect. For example, the massage end 13 may be used to stimulate the vagina while the massage portion 11 may be used to stimulate the clitoris. For another example, the massage end 13 may be used to stimulate the rectum while the massage portion 11 may be used to stimulate the prostate. In an alternatively embodiment, only one of the massage portion 11 and the massage end 13 has a vibrating component disposed therein.

In this embodiment, the driving mechanism 20 has the similar structure as the driving mechanism 20 in the first embodiment. The driving mechanism 20 of this embodiment is no more described in detail.

FIGS. 11-12 show a third embodiment of the sexual stimulation device of the present application, which differs from the first embodiment mainly in the massage portion. In this embodiment, the shell 10 of the sexual stimulation device 100 is generally elongated and rod-shape. A middle portion of the shell 10 is laterally to form the base portion 52 and the massage portion 11 is connected to the base portion 52. Specifically, the middle portion of the shell 10 is concaved inwardly recessed to form the base portion 52. The massage portion 11 is set in the base portion 52 and partly extends beyond the base portion 52 through its open side 521. Preferably, protruding dots 34 are provided on an outer surface of the massage portion 11 to enhance the stimulation effect of the massage portion 11.

The shell 10 is provided with a driving mechanism 20, which includes a driving module 22 and a first driving rod 24. The first driving rod 24 includes a first end 24a and a second end 24b opposite to the first end 24a. The first end 24a is connected to the driving module 22, and the second end 24b is connected to the massage portion 11. Under the action of driving module 22, the massage portion 11 rotates along with the second end 24b around the first end 24a, forming an annular trajectory, which can generate a kneading effect on the human body.

In this embodiment, the front end of the shell 10 forms a massage end 13, and a second vibrating component 42, such as a vibration motor, is provided inside the massage end 13.
