Referring to FIGS. 1-5, a massage device 100 according to an embodiment of the present application includes a shell 20, a driving assembly 30 supported by the shell 20, and a massage member 40 connected to the driving assembly 30 in a transmission way. During use, a front portion of the shell 20 may be inserted into a human body, particularly a rectum or a vagina of the human body. In this embodiment, a vibration motor 50 is set inside the front portion of the shell 20, which generates a stimulation effect on a clitoris or a prostate of the human body through vibration.

In this embodiment, the shell 20 in whole is elongated and generally rod-shaped. A moving space 22 is defined in a middle portion of the shell 20 along its longitudinal direction (i.e., X-direction). The massage member 40 at least partly extends into the moving space 22 of the shell 20, and is driven to rotate in the moving space 22 under the action of the driving assembly 30. The rotating massage member 40 generates a kneading stimulation effect on a vaginal wall or a rectal wall of the human body, further stimulating the clitoris or the prostate, making it easier for the users to reach orgasm, thereby obtaining a more comfortable sexual experience.

In this embodiment, as shown in FIG. 3 and FIG. 4, the moving space 22 extends through two opposite sides of the shell 20, such as, extends along Z-direction through top and bottom sides of the shell 20. That is, in the Z-direction, a depth of the moving space 22 is substantially equal to a thickness of the shell 20. Two openings 23 are defined at top and bottom sides of a lateral wall of the shell 20, respectively. The moving space 22 communicates with an external environment out of the shell 20 through the openings 23, and the massage member 40 may extend into the external environment via the opening 23 to directly contact the vaginal wall or rectal wall.

In this embodiment, a size of the whole massage member 40 in the Z-direction is greater than a depth of the moving space 22 in the Z-direction, top and bottom portions of the massage member 40 extend beyond the moving space 22 of the shell 20 into the upper and lower sides of the shell 20 through the openings 23, respectively. Thus, the massage member 40 can simultaneously come into contact with portions of the rectum wall/vaginal wall located at its upper and lower sides, which increases a stimulated area of the massage member 40 of the present massage device 100 on the human body.

As shown in FIGS. 5-7, the massage member 40 is shaped like an annular belt, and specifically, shaped like an elliptical caterpillar belt. An outer circumferential surface of the massage member 40 is provided with a plurality of protrusions 42, which extend outwardly from the moving space 22 of the shell 20 to contact the rectum wall/vaginal wall directly, further improving the stimulation effect on the rectum wall or the vaginal wall. The protrusions 42 may be convex points, convex pillars, convex strips, convex ribs, etc., distributed at intervals along a circumferential direction of the massage member 40. In this embodiment, the protrusions 42 are shaped as elongate convex ribs.

FIGS. 8-10 show alternative embodiments of the massage member. As shown in FIG. 8, the massage member 40a has a plurality of protrusions 42a shaped like balls provided on its outer circumferential surface. As shown in FIG. 9, the protrusions 42b of the massage member 40b are shaped like arc sheets. As shown in FIG. 10, the protrusions 42c of the massage member 40c are shaped like pillars. It should be noted that the protrusions are designed for enhancing the stimulation effect, and may be modified according to needs and should be limited to the specific embodiments.

In addition, the depth of the moving space 22 may be less than the thickness of the shell 20 in the Z-direction. In this case, the moving space 22 may only penetrate one of the top and bottom sides of the shell 20. For example, as shown in FIG. 11, the massage device 200 has a moving space 22 only penetrating the top side of the lateral wall of the shell 20, so that only the top portion of the massage member 40 extends into the external environment over the shell 20. During in use, the massage member 40 is driven to rotate, kneading a portion of the rectum wall or the vaginal wall nestled to the open side of the moving space 22.

As shown in FIGS. 5-7, the driving assembly 30 includes a driving motor 32, a driving wheel 34 connected to the driving motor 32, and a driven wheel 36 that cooperates with the driving wheel 34. As shown in FIG. 4, the driving motor 32 is set in a rear portion of the shell 20, while the driving wheel 34 and the driven wheel 36 both are received in the moving space 22. The massage member 40 is mounted around and engaged with the driving wheel 34 and the driven wheel 36. During use, the driving motor 32 drives the massage member 40 to rotate in the moving space 22 through the driving wheel 34 and the driven wheel 36.

As shown in FIG. 2 and FIG. 5, the moving space 22 is generally closed in its circumferential direction, and the shell 20 forms two support arms 24 at left and right sides, of the moving space 22, respectively. The driving wheel 34 and the driven wheel 36 are arranged side by side in the X-direction, wherein the driving wheel 34 is set adjacent to a rear end of the moving space 22, and is pivotally connected to the support arms 24 by a first shaft 35; and, the driven wheel 36 is set adjacent to a front end of the moving space 22, and is pivotally connected to the support arms 24 by a second shaft 37.

In this embodiment, the first shaft 35 and the second shaft 37 both extend laterally, such as along Y-direction. The first shaft 35 may be formed separately and then connected to the shell 20 and the driving wheel 34. The second shaft 37 may be formed separately and then connected to the shell 20 and the driven wheel 36. Alternatively, the first shaft 35 may be integrally formed with the shell 20 or the driving wheel 34; and/or, the second shaft 37 may be integrally formed with the shell 20 or the driven wheel 36.

In this embodiment, the driving wheel 34 and the driven wheel 36 both are gears, and an inner circumferential surface of the massage member 40 has a plurality of teeth 44 provided thereon, which are evenly spaced along the circumferential direction of the massage member 40 and mesh with the driving wheel 34 and the driven wheel 36. In this way, when the driving motor 32 drives the driving wheel 34 to rotate, the driving wheel 34 drives the massage member 40 engaged with it to rotate, and the massage member 40 drives the driven wheel 36 engaged with it to rotate, so that the massage member 40 can rotate continuously.

A transmission unit, such as a gear unit 38, is provided between the driving motor 32 and the driving wheel 34. As a transmission mechanism, the gear unit 38 can not only transmit the torque from the driving motor 32 to the driving wheel 34, but also change the direction of torque transmission as needed. In a specific embodiment, as shown in FIGS. 6-7, the gear unit 38 includes a first gear 381, a second gear 383, a third gear 385, and a fourth gear 387.

Among them, the first gear 381 is mounted around a shaft 33 of the driving motor 32, and the two are preferably arranged coaxially; the second gear 383 meshes with the first gear 381, preferably with a diameter smaller than that of the first gear 381; the third gear 385 and the second gear 383 are arranged coaxially, and the two can be connected integrally; the fourth gear 387 meshes with the third gear 385, preferably the third gear 385 and the fourth gear 387 both are bevel gears. The driving wheel 34 is coaxial with the fourth gear 387, wherein the diameter of the driving wheel 34 is greater than the diameter of the fourth gear 387.

By matching of the two bevel gears 385 and 387, a 90-degree change in the direction of torque transmission can be achieved, and thus the axial direction of the driving wheel 34 may be perpendicular to the shaft 33 of the driving motor 32. Through the gear unit 38, the torque transmission direction can be changed and long-distance deceleration torque transmission can be achieved.

After the high-speed rotation of the driving motor 32 is decelerated step by step, the driving wheel 34 is driven to rotate at an appropriate speed, thereby driving the massage member 40 to rotate at an appropriate speed. In the illustrated embodiment, the driving motor 32, the first gear 381, and the second gear 383 are set inside the rear portion of the shell 20, and the third gear 385 and the fourth gear 387 are accommodated in one of the support arms 24 of the shell 20. The third gear 385 is connected to the second gear 383 through an elongated rod 39, allowing the driving wheel 34 to be arranged in the moving space 22.

In this embodiment, a non-circular shaped, such as square-shaped, connecting hole 341 is defined in the center of the driving wheel 34, and the fourth gear 387 extends outward to form a connecting portion 389. The connecting portion 389 is inserted into the connecting hole 341 and fixed in a circumferential direction through shape matching. In this way, the fourth gear 387 can drive the driving wheel 34 to rotate synchronously. It should be understood that the fourth gear 387 may be assembled to the driving wheel 34 in other ways, as long as it can drive the driving wheel 34 to rotate.

It should be understood that the quantity, structure, size, etc. of the gears in the gear unit 38 may be adjusted as needed. In addition, other transmission mechanisms, such as worm gears, pulleys, etc., or a combination of multiple transmission mechanisms may be provided between the driving motor 32 and the driving wheel 34. That is, the transmission mechanism between the driving motor 32 and the driving wheel 34 is not limited to the gear transmission shown in the drawings. Furthermore, in some embodiments, the driving motor 32 may drive the driving wheel 34 to rotate directly, omitting the transmission mechanism.

In this embodiment, the rear portion of the shell 20 is configured as a handle of the massage device 100, and function buttons 52 are provided on an outer wall of the handle. In the handle, a control circuit board 54 is provided, which connects electrically to the vibration motor 50, the driving motor 32, the buttons 52 and other electronic components to form a control circuit. The users may control the operation of the present massage device, such as control the direction and speed of the driving motor 32, control the vibration frequency of the vibration motor 50 inside the front portion of the shell 20, and etc. through the buttons 52 on the handle of the shell 20.
