Referring toFIGS.1-4, a massage device according to an embodiment of the present application is shown. In this embodiment, the massage device100includes a shell10, a first driving unit30mounted in the shell10, and a first massage portion12driving by the first driving unit30.

In this embodiment, the shell10is elongated and generally rod-shaped, and a moving space14is defined in a middle portion of the shell10. The first massage portion12extends into the moving space14, and is movable in the moving space14. In this embodiment, the moving space12extends through two opposite sides of the shell10along its lateral direction, i.e., Z-direction in the drawings, and thus two openings15are defined at two sides, such as top and bottom sides, of a lateral wall of the shell10, respectively. The moving space14communicates an exterior environment out of the shell10through the openings15.

Under the driving of the first driving unit30, the first massage portion12is capable of extending into the exterior environment out of the shell10via each of the openings15, thereby stimulating a part of the human body around the shell10. Particularly, the shell10is configured to be inserted into a rectum or a vagina of the human body along its longitudinal direction, i.e., X-direction in the drawings, and the first massage portion12is configured to knead a rectum wall or a vaginal wall.

As shown in the drawings, the opening15of shell10is generally perpendicular to the Z-direction. The first massage portion12moves in a longitudinal plane of the shell10, such as the XZ-plane, which is generally perpendicular to the opening15. During the movement of the first massage portion12, its massage surface, such as its upper and lower surfaces in the Z-direction, may extend outwardly to the exterior environment out of the shell10through the openings15. Alternatively, the first massage portion12may totally return into the moving space14of the shell10, so as to get greater swing amplitude when it extends outwardly next time, thereby obtaining a greater stimulation force. In some embodiments, the massage surface of the first massage portion12is convex, and may be provided with protrusions or patterns to further enhance the stimulation effect.

In an embodiment, the first driving unit30includes a swing arm32. The swing arm32is arranged in the shell10with one end thereof connected to the first massage portion12, thereby driving the first massage portion12to do reciprocating motion. Specifically, the swing arm32is slidably connected to the shell10by a first shaft40, allowing the first massage portion12to do linear reciprocating motion relative to the shell10. At the same time, the swing arm32is rotatably connected to the shell10by a second shaft42, allowing the first massage portion12to do reciprocating swinging relative to the shell10. The linear reciprocating motion and reciprocating swinging of the first massage portion12are superimposed, finally forming an annular trajectory, such as a circular trajectory, an elliptical trajectory and the like. Thus, the first massage portion12is driven to knead the vaginal wall or the rectum wall, stimulating the crus of clitoris or the prostate.

By means of setting the moving space14, the first massage portion12may swing back and forth between the interior and exterior of the shell10, thereby getting a larger moving range and generating greater force on the human body, enhancing the stimulation effect. Preferably, the moving space14is elongated, making the first massage portion12have a larger swinging radius. It should be understood that the setting of the moving space14is to make the interior space and exterior space of the shell10be communicated with each other, so as to increase the moving range of the first massage portion12. In some embodiments, the moving space14of the shell10may be a blind groove with one side being opened and another side being closed. For example, the moving space14may only penetrate the upper side of the lateral wall of the shell10, so that the first massage portion12can extend into the external environment at the upper side of the shell10.

In this embodiment, as shown inFIGS.3-4, the shell10may be a double-layer structure, and includes an inner shell10aand an outer shell10bcovering the inner shell10a. The inner shell10ais made of hard materials such as plastic, metal, etc., which has a relatively high strength and thus provides support for the components mounted inside the shell10, such as the first driving unit30and etc. The outer shell10bis made of flexible materials such as silicone, rubber, and etc., and has a soft touch. In other embodiments, the outer shell10bmay be made of other flexible materials that can directly contact the skin, which is not limited in the present application.

As shown inFIG.3, the first massage portion12may be a double-layer structure, and includes a hard layer12aand a soft layer12bcovered on the hard layer12a. The hard layer12amay be part of the inner shell10a, while the soft layers12bmay be part of the outer shell10b. In this embodiment, the soft layer12bof the first massage portion12is integrally connected to the outer shell10b, and wrinkles13are formed at a joint of the soft layer12band the outer shell10b. The hard layer12aof the first massage portion12is disconnected from the inner shell10aat a position corresponding to the wrinkles13, making the first massage portion12be easier to deform during movement. The first massage portion12thus may have a larger swing and/or movement amplitude, thereby having a larger stimulation range.

In an embodiment, as shown inFIGS.5-7, the swing arm32is generally an elongated plate, wherein its longitudinal direction is consistent with the longitudinal direction of the shell10(i.e., X-direction), and its width direction is consistent with a depth direction of the moving space (i.e., the Z-direction). The end of the swing arm32is inserted into the hard layer12aof the first massage portion12, and is fixedly connected to the hard layer12athrough snap-fitting, welding, bonding, interference fitting, and etc., so as to drive the entire first massage portion12to move. The hard layer12acan better transmit the force of the swing arm32to the first massage portion12, allowing the first massage portion12to have a larger swing and/or movement range, thereby having a larger stimulation range.

A middle portion of the swing arm32is slidably connected to the shell10through the first shaft40, and another end of the swing arm32is pivotally connected to the shell10through the second shaft42. The first shaft40and the second shaft42both extend along Y-direction, being perpendicular to the swing arm32. When the second shaft42is driven to rotate around an axis O in a longitudinal plane, such as the XZ-plane, due to the limitation of the first shaft40, the rotational motion of the second shaft42is transformed into the linear reciprocating motion of the swing arm32in the X-direction and the reciprocating swinging in the XZ-plane, finally driving the first massage portion12connected to the swing arm32to move along a circular trajectory.

In an embodiment, the swing arm32is provided with a sliding groove321at the middle portion thereof. The sliding groove321is elongated and extends along the X-direction. The first shaft40is inserted into the sliding groove321, with a diameter generally equivalent to a width of the sliding groove321but much smaller than a length of the sliding groove321. Through the cooperation of the first shaft40and the sliding groove321, the swing arm32can slide relative to the first shaft40along its length direction; and the swing arm32and the first shaft40are relatively fixed in the width direction of the swing arm32. In the illustrated embodiment, the shell10is provided with a first support seat20at a position corresponding to the first shaft40, and an end of the first shaft40extends beyond the sliding groove321and is inserted into the first support seat20.

In an embodiment, the first driving unit30further includes a gearbox34and a rotary member36connected to the gearbox34for power transmission. Referring toFIG.8, the gearbox34includes a motor341and a gear unit343. The motor341serves as a driving component of the massage device100and has an output shaft342rotating at high-speed. The gear unit343includes a gear housing345and a plurality of gears347arranged in the gear housing345. The gears347mesh with each other, and a reduction ratio of the whole gear unit343can be determined according to the gear ratios between the meshed gears347. In an embodiment, the reduction ratio of the gear unit343is not less than 4:1 and not more than 100:1, and an output speed of the gearbox34is not exceed 1000 rpm. That is, a speed of an output shaft349of the gearbox34does not exceed 1000 rpm.

The rotary member36is connected to the output shaft349of the gearbox34in a transmission way. Under the driving of the gearbox34, the rotary member36rotates about the axis O, wherein the axis O may be a central axis of the rotary member36. Preferably, a speed of the rotary member36does not exceed 1000 rpm. The shell10is provided with a second support seat22at a position corresponding to the rotary member36, and a rotating shaft361extends outwardly from the rotary member36into the second support seat22. Preferably, the rotating shaft361is rotatably inserted into the second support seat22. The second shaft42is eccentrically arranged on the rotary member36, and rotates around the axis O under the driving of the gearbox34.

In an embodiment, the second shaft42and the rotary member36may be integrally formed as one piece. The another end of the swing arm32, which is away from the first massage portion12, is provided with a shaft hole323, and the second shaft42may be rotatably inserted into the shaft hole323. Preferably, a fixing hole44is provided in the second shaft42, and a rod portion of the fixing member46, such as pins, rivets, screws, etc., is inserted into the fixing hole44of the second shaft42, and a head portion of the fixing member46abuts against the swing arm32at a periphery of the shaft hole323, so as to fix the second shaft42and the swing arm32in the Y-direction. In this way, the second shaft42will not automatically detach from the shaft hole323of the swing arm32, ensuring the connection stability between the swing arm32and the rotary member36.

In some embodiments, the second shaft42may be integrally formed on the swing arm32, and a shaft hole323may be provided on the rotary member36corresponding to the second shaft42. Alternatively, the second shaft42may be formed separately and then pivotally connected to the swing arm32and/or rotary member36.

When the gearbox34is started, the output shaft342of the motor341rotates at high speed. After being slowed down by the gear unit343, the rotary member36rotates at an appropriate speed, such as no more than 1000 rpm. The second shaft42rotates around the axis O, driving the swing arm32to rotate. The swing arm32generates displacement in both its length and width directions. Due to the engagement between the first shaft40and the sliding groove321, the movement of the swing arm32in its length direction is not restricted, allowing the swing arm32to slide along its sliding groove321relative to the first shaft40; and the movement of the swing arm32in its width direction is limited by the first shaft40, causing the swing arm32to rotate relative to the second shaft42and thus generate swing.

As shown inFIGS.9-12, as the rotation angle of the second shaft42around the axis O changes, the swinging center of the swing arm32continuously changes. The swing arm32simultaneously generates two different reciprocating movements, namely the linear reciprocating movement of the swing arm32in the X-direction and the reciprocating swing of the swing arm32in the XZ-plane. The combination of these two reciprocating movements drives the first massage portion12connected to the swing arm32to move along a circular or elliptical trajectory in the XZ-plane, as shown by the dashed line inFIG.13.

Preferably, the length of the swing arm32is not less than 2 centimeters, allowing the swing arm32and the first massage portion12connected to the swing arm32to have a larger moving range, thereby an area of the human body kneaded by the first massage portion12being enlarged and accordingly a stimulation effect being better. In an embodiment, the trajectory of the first massage portion12is substantially an elliptical trajectory, wherein the major axis of the elliptical trajectory is not less than 1 centimeter. In another embodiment, the trajectory of the first massage portion12is substantially a circular trajectory, wherein the diameter of the circular trajectory is not less than 1 centimeter. In the illustrated embodiment, the swing arm32in whole is elongated in the X-direction, but its middle portion is bent to facilitate the arrangement of the gearbox34. In some embodiments, the swing arm32may be a longitudinal, flat structure.

Compared to the existing massage devices which stimulate the human body by linear reciprocating motion, the first massage portion12of the present massage device moves along an annular trajectory, and thus kneads the sensitive area, such as the rectum or vagina of the human body. An area of the human body kneaded by the first massage portion12is enlarged and accordingly a stimulation effect is better. Moreover, the first massage portion12kneads the human body, which is similar to the motion of the hand, providing a more comfortable sexual experience.

In an embodiment, as shown inFIGS.5-7, a steering unit38is provided between the rotary member36and the gearbox34. By means of the steering unit38, the direction of power transmission may be changed, facilitating the arrangement of the gearbox34. In the illustrated embodiment, the gearbox34is arranged with its output shaft349being generally parallel to the swing arm32. The steering unit38is located between the gearbox34and the swing arm32. In this way, the space in the longitudinal direction of the shell10may be fully utilized, which is conducive to the miniaturization of the device.

Specifically, the steering unit38is a steering gear unit, and includes a plurality of gears that mesh with each other, such as a first gear38a, a second gear38b, and etc. The first gear38ais mounted around the output shaft349of the gearbox34, preferably the first gear38aand the gearbox34are arranged coaxially. The second gear38bis mounted around the rotating shaft361of the rotary member36, preferably the second gear38band the rotary member36are integrally formed as on piece. The first gear38aand the second gear38bmay be bevel gears and mesh with each other, achieving a change of 90 degrees in the direction of power transmission between the gearbox34and the rotary member36.

In other embodiments, the direction of power transmission can be determined based on the internal space of the massage device100, and the angle that needs to be changed is not limited to 90 degrees. Users can choose corresponding type of steering unit according to their needs to achieve direction change, which should not be limited by specific embodiments. In some embodiments, the steering unit38may also be integrated inside the gearbox32, thereby a separate steering unit is no longer needed. Alternatively, in some embodiments, there is no need for direction change between the gearbox34and the rotary member36, and thus the steering unit38may be omitted.

In an embodiment, the first driving unit30further includes a first vibration motor39mounted inside the first massage portion12. When the first vibration motor39is activated, it drives the first massage portion12to vibrate at a certain frequency, stimulating the human body, such as the vagina or the rectum through vibration. It should be understood that during use, the vibration frequency of the first vibration motor39may be adjusted according to the user's needs.

In an embodiment, a front end of the shell10, which is a portion of the shell10located at a front side of the moving space14, acts as a second massage portion16. A second driving unit, such as a second vibration motor50, is set in the second massage portion16. When the second vibration motor50is started, it drives the second massage portion16to vibrate at a certain frequency, stimulating the human body, such as the vagina or the rectum through vibration.

The second massage portion16and the first massage portion12are located at different positions of the shell10, allowing for stimulating two different positions of the human body at the same time. Overall, the massage device100has a larger stimulation range and further enhanced stimulation effect.

In an embodiment, the shell10is further provided with a third massage portion18. In the illustrated embodiment, the third massage portion18extends upwards and forwards by bending and extending from a rear end of the moving space14of the shell10, generally above and separated from the first massage portion12. A third driving unit, such as a third vibration motor52, is set in the third massage portion18. When the third vibration motor52starts, it drives the third massage portion18to vibrate at a certain frequency, stimulating the human body, such as the vulva, particularly the clitoris.

The third massage portion18, the first massage portion12, and the second portion section16are located at different positions on the shell10, allowing for stimulating three different positions of the human body at the same time. Accordingly, the massage device100has a larger stimulation range and further enhanced stimulation effect.

In an embodiment, a rear end of the shell10serves as a handle19, and buttons70are provided on the handle19. A control circuit board72is provided in the handle19, and forms a control circuit with the gearbox34, the first and/or second and/or third vibration motors, and etc. The buttons70may be touch type buttons and/or mechanical buttons, and the users can control the operation of the massage device100through the buttons70, including controlling the speed and direction of the gearbox34, the vibration frequency of the first, second and third vibration motors, and etc. A battery74, preferably a rechargeable battery, is provided inside the shell10. The battery74is connected to the control circuit board72electrically and serves as a power source of the massage device100.

Preferably, after being assembled with the first driving unit30, the second vibration motor50, the third vibration motor52, the control circuit board72, the battery74, etc., the inner shell10ais integrally formed by over-molding on the inner shell10a, achieving good sealing effect for the components inside the shell10. The outer shell10bplays a waterproof and dustproof role, facilitating the cleaning and storage of the massage device100. The end of the swing arm32may be integrally fixed in the hard layer12aof the first massage portion12during the forming the soft layer12b, which not only simplifies production and assembly, but also enhances the connection strength between the first massage portion12and the swing arm32, allowing the first massage portion12to have a larger swing amplitude.

During use of the massage device100of this application, the user may activate the gearbox34of the first driving unit30to achieve a kneading effect to the vagina/rectum through the movement of the first massage portion12; and/or, activate the first vibration motor39of the first driving unit30to achieve a stimulation effect to the vagina/rectum through the high-frequency vibration of the first massage portion12; and/or, activate the second vibration motor50to enhance a stimulation effect to the vagina/rectum through the high-frequency vibration of the second massage portion16; and/or, activate the third vibration motor52to enhance a stimulation effect to the vulva through the high-frequency vibration of the third massage portion18, which can be more convenient to use.

By means of setting the moving space14in the shell10, the present massage device100provides a wider moving range for the first massage portion12, allowing the first massage portion12to have greater force and effectively improve the stimulation effect. Further, by means of slidable and rotatable cooperation between the swing arm32and the shell10, the first massage portion12swings back and forth and moves back and forth simultaneously in the XZ-plane, finally forming an annular trajectory. This generates a kneading effect on the human body, enlarging the stimulation area and improving the sexual experience. In other embodiments, the shape of the shell10may be modified according to the part of the human body to be stimulated, which should not be limited to specific embodiments.

Finally, it should be noted that: the above merely describes preferred embodiments of the present application without intention to limit the scope of the present application. Although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions described in the foregoing embodiments can still be modified, or some of the technical features can be equally replaced. Any modifications, equivalent replacements, improvements, and etc. made within the spirit and principle of the present application should be within the scope of the present application.
