[0007] Referring to FIG. 1 to FIG.12, a massage module 100 of the first embodiment of the present disclosure is shown. The massage module 100 is capable of being inserted into a hole-like portion to be massaged, e.g. a vagina of a female human body, to provide multi-stimuluses to the user.

[0008] The massage module 100 includes a main massage portion 1, most of which is inserted into the hole-like portion to be massaged, a vice massage portion 2 extending from the main massage portion 1, a massage head 30 located in a non-end portion of the main massage portion 1, a driving device 60 configured to control the main massage portion 1 and / or other massage functions of the massage module 100, and a shell 90 configured to receive function elements, such as the driving device 60 of the massage module 100.

[0009] The main massage portion 1 includes a head portion 10, a connecting portion 20 and a handle 50. The connecting portion 20 connects the head portion 10 and the handle 50. The connecting portion 20 includes a sub-massage portion 21 configured to provide a second stimulus to hole-like portion to be massaged. The massage head 30 is located corresponding to the sub-massage portion 21. The shell 90 includes a handle housing 91 corresponding to the handle 50, an internal space of the handle housing 91 forms a cavity 911 to receive the driving device 60, the control buttons 11 and so on. The connecting portion 20 includes two support arms 93 extending from two opposite edges of a top end of the handle housing 91 along the length direction of the main massage portion 1. The length direction is parallel to the insertion direction X. The two support arms 93 are arranged at an interval, and a hollow space 931 is defined between the two support arms 93. The hollow space 931 can be also formed by a recess penetrates through the shell 90 in a thickness direction of the shell 90 perpendicular to the length direction, thereby forming a first opening 9311 and a second opening 9313 opposite to the first opening 9311. Both the first opening 9311 and the second opening 9313 are communicated with the hollow space 931 and are intercommunicating the hollow space 931 inside the shell 90 with an outside environment space out of the shell 90. The hollow space 931 can be for example an elongated arc-shaped hole. In some exemplary embodiments of the present disclosure, as shown in FIG. 17, the hollow space 931 can be for example a recess 18 formed in the shell 90 by depressing a side of the shell 90 inward along the thickness direction of the shell 90 without penetrating through another side of the shell 90. The recess 18 includes side walls defined by the two support arms 93, a bottom wall defined by the remained shell and an opening (e.g. the first opening 9311) communicating with the hollow space 931.

[0010] The sub-massage portion 21 includes the massage head 30 and the hollow space 931, and the massage head 30 moves reciprocally with respect to the main massage portion 1 under the control of the driving device 60. In one example embodiment of the present disclosure, the massage head 30 performs synchronous or asynchronous linear movement following the movement of the head portion 10. Referring to FIG. 4, when the massage head 30 is inserted into the hole-like portion to be massaged, the sub-massage portion 21 is also inserted into the hole-like portion to be massaged, so as to provide a second stimulus to hole-like portion to be massaged. The second stimulus is generated by the movements of the massage head 30. At least a portion of a massage surface 35 of the massage head 30 is capable of protruding out of the shell 90 via at least one of the first opening 9311 and the second opening 9313. When the massage head 30 performs the linearly reciprocally movement in the length direction, the massage surface 35 repeatedly applies pressure or stimulation to different positions of a specific area of the object being contacted following the movements of the massage head 30.

[0011] Referring to FIG. 9, an exemplary embodiment of the massage head 30 is shown. The massage head 30 has a T-shaped structure and includes a soft casing 31 corresponding to a lateral portion of the T-shaped structure which has two free ends 31a, 31b, and a connecting part 32 corresponding to a longitudinal portion of the T-shaped structure, which extends from a center of the soft casing 31. The connecting part 32 is fixedly connected to an extension bar 45 (as shown in FIG.6). Most of the soft casing 31, the connecting part 32 and some of the extension bar 45 are located in the hollow space 931. The soft casing 31 includes a column 33 connected to the connecting part 32 and two protrusions 34 corresponding respectively to the two free ends 31a, 31b, and the two protrusions 34 protrude outside the shell 90 through the first opening 9311 and the second opening 9313 respectively. In this embodiment, the connecting part 32 is perpendicular to the soft casing 31. The soft casing 31 can be for example form by a second motor 311. The second motor 311 is a vibration motor. The second motor 311 generates vibrations under control of a control button 11. the massage head 30 can generate a vibration effect while sliding, thereby enhancing the massage experience for users. It can be understood that the vibration speed of the second motor 311 can be controlled by the control button 11. When the massage head 30 moves reciprocally in the hollow space 931 with respect to the shell 90, the massage head 30 massages the second area of the hole-like portion to be massaged.

[0012] Referring to FIG. 1, the head portion 10 is configured to be inserted into the hole-like portion to be massaged along the insertion direction X to provide a first stimulus to a first area of the hole-like portion to be massaged. The first stimulus can be for example a sensation of stimulation generated by at least one of friction, tapping, or vibration applied on the object to be contacted. In one example embodiment, the frictional motion generated by the action of inserting or withdrawing from the body forms the first stimulus. The driving device 60 is correspondingly received into the cavity 911 (as shown in FIG. 5) defined by the handle housing 91. In one exemplary embodiment of the present disclosure, the handle housing 91 is a part of the shell 90, and is integrally formed with other portions, e.g. the support arms 93, of the shell 90. A through opening 912 (as shown in FIG. 2) is defined in a partition wall 914 of the handle housing 91 that is configured to separate the hollow space 931 from the cavity 911. A transmission function element of the driving device 60 is connected to the massage head 30 via the through opening 912, thereby the driving device 60 drives the massage head 30 to move. In one exemplary embodiment of the present disclosure, the extension bar 45 passes through the cavity 911 via the opening 912 to enter the hollow space 931.

[0013] Referring to FIG. 2, FIG. 5, FIG. 8 and FIG. 9, the driving device 60 is installed within the cavity 911. The driving device 60 includes a driving member 13, the circuit board 15 and a transmission mechanism 40. A portion of the transmission mechanism 40 extends and protrudes towards the hollow space 931 through the through opening 912 and connects to the massage head 30. In the exemplary embodiment of the present disclosure, the sliding movement of the massage head 30 in the hollow space 931 is performed by the coordination between the transmission mechanism 40 and the driving member 13. The sliding movement of the massage head 30 refers to the reciprocating movement of the massage head 30 forward and backward in any one direction of the following directions: the insertion direction X, a length direction of the extension bar 45, a telescopic direction of the extension bar 45, and a direction pointing from the handle 50 to the head portion 10. Referring to Fig. 5, the driving member 13 is fixedly installed within the cavity 911, an elongated rotating shaft 131 is connected to an output shaft of the driving member 13 and is configured for engaging with the transmission mechanism 40. In some embodiments of the present disclosure, the driving member 13 can be a motor.

[0014] Referring also to Figs.9 and 10, the transmission mechanism 40 includes a screw rod 41, a sliding block 43 and the extension bar 45. The screw rod 41 has a perforation 413 in a length direction of the screw rod 41. The rotating shaft 131 enters and passes through the perforation 413, so that the screw rod 41 is sleeved on the rotating shaft 131. The rotating shaft 131 keeps rotating, driven by the driving member 13, so as to drive the screw rod 41 to rotate. The screw rod 41 includes a sliding groove 411 which is spirally arranged along a circumferential direction of the screw rod 41. The sliding block 43 is movably sleeved on the screw rod 41 and slides along the sliding groove 411. One end of the extension bar 45 is connected to the sliding block 43, and the other end extends towards the hollow space 931 through the through opening 912. In some exemplary embodiments of the present disclosure, the extension bar 45 and the screw rod 41 are arranged parallel to each other at an interval.

[0015] The sliding block 43 is capable of moving forward along the sliding groove 411 from the end of the screw rod 41 close to the driving member 13 towards the end of the screw rod 41 far away from the driving member 13, or can move backward along the sliding groove 411 from the end of the screw rod 41 far away from the driving member 13 towards the end of the screw rod 41 close to the driving member 13, so that the sliding block 43 reciprocally moves with respect to the screw rod 41. The sliding groove 411 includes a plurality of inclined chutes 4111. These inclined chutes 4111 are arranged to form two spiral paths which continuously encircles the circumferential surface of the screw rod 41 from one end to the other and intersects with each other. Referring also to FIG. 10, when viewed from one side of the screw rod 41, two adjacent inclined chutes 4111 are arranged as a V-shape structure, while two non-adjacent inclined chutes 4111 in consecutive V-shape structures are parallel to each other. Consequently, every three adjacent inclined chutes 4111 together form an N-shaped arrangement. It can be understood that the specific structure of the sliding groove 411 can be designed according to actual demands.

[0016] Referring to FIG. 9, FIG. 11 and FIG. 12, the sliding block 43 is substantially cross-shaped, and includes a longitudinal arm 43b arranged along the insertion direction X and a transverse arm 43a perpendicular to the longitudinal arm 43b. The longitudinal arm 43b includes a first portion 431 and a second portion 433 arranged opposite to the first portion 431, and the transverse arm 43a includes a third portion 4333 and a fourth portion 434 arranged opposite to the third portion 432. The first portion 431 is sleeved to the screw rod 41 and the second portion 433 is connected to the extension bar 45. A first through hole 4315 is defined at the intersection of the first portion 431 and the second portion 432, and passes through the sliding block 43 in the insertion direction X. The screw rod 41 is inserted into the first through hole 4315, so that the sliding block 43 is sleeved on the screw rod 41. The top of the first portion 431 far away from the second portion 433 defines a second through hole 4317, and the second through hole 4317 communicates with the first through hole 4315. A accommodating space is defined inside the first portion 431 so as to receive a plug 435 and a limiting block 4313. The accommodating space communicates with the first through hole 4315 and the second through hole 4317. The plug 435 is configured to move along the spiral paths defined by the screw rod 41, and the limiting block 4313 is configured to fixedly engage the plug 435 with the sliding block 431.A portion of the plug 435 is accommodated in the second through hole 4317. Another portion of the plug 435 is extended to the first through hole 4315 and contacts the sliding groove 411.

[0017] Referring to FIG. 12, in some embodiments of the present disclosure, the plug 435 includes a rotating end 4351 received and rotatably moving in the second through hole 4317 and an arc sliding end 4353 integrated with the rotating end 4351. The arc sliding end 4353 is directly engaged in the sliding groove 411. A sliding rail 913 is formed by internal walls located inside the shell 90.The third portion 432 is received and slidably moves in the sliding rail 913, so that these internal walls limit the third portion 432 to move up and down, and thus the sliding block 43 cannot move up and down with respect to the shell 90.

[0018] A third through hole 4331 is defined in the middle of the second portion 433. One end of the extension bar 45 is directly inserted into the third through hole 4331 so as to connect to the sliding block 43. After the extension bar 45 and the screw rod 41 are assembled, the extension bar 45 and the screw rod 41 are parallel to each other and arranged at an interval.

[0019] Referring also to FIG. 6 and FIG.7, a cover 70 made of elastic material covers outer surfaces of the shell 90 except the first opening 9311 and the second opening 9313, thereby forming a moving space 17 corresponding to the hollow space 931. The moving space 17 is communicated with an outside environment space out of the shell 90. In the moving space 17, the cover 70 covers the support arms 93, a first wall of the shell 90 between the hollow hole 931 and the handle 90, and a second wall of the shell 90 between the hollow hole 931 and the head portion 10.

[0020] The cover 70 covers the main massage portion 1, the massage head 30 and the vice massage portion 2 to play a waterproof role. The shell 90 is made of a solid material. The cover 70 further includes a first cover 71 and a second cover 73. The first cover 71 is in a flat state, and the second cover 73 is in a wrinkled state. The second cover 73 is located on a path where a telescopic movement is generated. In this embodiment, the second cover 73 is arranged to connect a first region from the partition wall 914 to the massage head 30 and connect a second region from the massage head 30 to an inner wall of the head portion 10. The sliding motion of the massage head 30 drives the second cover 73 to telescopically move with respect to the shell 90. The ends of the massage head 30 protruding from the shell 90 are covered by the cover 70, and the cover 70 is a curved structure. The second cover 73 has a folded structure. When the massage head 30 moves from the handle 50 towards the head portion 10, the portion of the second cover 73 close to the head portion 10 is compressed, while the portion far away from the head portion 10 is stretched. When the massage head 30 moves from the head portion 10 towards the handle 50, the portion of the second cover 73 far away from the head portion 10 is compressed, while the portion close to the head portion 10 is stretched, so as to move telescopically follow the massage head 30.

[0021] Referring to FIG. 8, the inside of the shell 90 forms various brackets used for fixing the positions of the driving device 60, a circuit board 15 and others. The shell 90 is made of hard material, so as to improve the bracing stability, enhance durability and extend the service life of the massage module 100. The back end of the shell is far from the head portion 10 provided with a control button 11. The control button 11 is directly connected to the circuit board 15 and used to control the massage module 100. It can be understood that the preferred position of the control button 11 is at the back end of the massage module 100 to avoid being far from the battery, thus reducing current transmission loss. It can be understood that the positions of the control button 11 are adjustable, or it can be replaced by a remote device or electronic product for control. It can be understood that the position of the control button 11 can be adjusted, and it can also be replaced by a remote device or an electronic product for control. Referring to FIG 3, the massage module 100 is also equipped with a hovering function. When activate the hovering function, the control button 11 can activate the control circuit board 15 to make the drive member 13 does not drive the rotating shaft 131 to rotate, and the second motor 311 generates vibration. The massage member 40 stay at a sensitive area of the hole-like portion and halt the telescopic function, generating only vibrations to maximize the stimulation of the sensitive area. Since everybody's sensitive areas vary, the hovering function helps users locate their sensitive area and then continuously stimulate them through vibrations. This sensitive area is typically a massage stimulation point, such as the G-spot.

[0022] The user operates the control button 11 to drive the drive member 13. The drive member 13 drives the rotating shaft 131 to rotate clockwise or counterclockwise, and the rotating shaft 131 drives the screw rod 41 to rotate. As the screw rod 41 rotates, the sliding end 4353 moves slowly towards a last inclined chute 4111, and thus the position in the sliding groove 411 of the plug 435 is changed. The third portion 432 of the sliding block 43 is restricted by the sliding rail 913 and cannot move vertically, so that the plug 435 can only drive the sliding block 43 to slide horizontally along the screw rod 41. The sliding of the sliding block 43 drives the extension bar 45 to move horizontally, thereby causing the extension bar 45 to drive the massage head 30 to slide. When the sliding end 4353 of the plug 435 rotates from the first inclined chute 4111a to the last inclined chute 4111n, due to the constant rotation direction of the rotating shaft 131, the plug 435 returns to the first inclined chute 4111a along the inclined chute 4111 on the other side of the sliding groove 411. The sliding block 43 drives the extension bar 45 to retract, thereby the massage head 30 reciprocally slides or performs reciprocal linear motions.

[0023] Furthermore, the transmission mechanism 40 can be driven by an externally applied force to rotate the plug 435, thereby changing the position of the plug 435 within the sliding groove 411.

[0024] Furthermore, the plug 435 and the screw rod 41 can rotate simultaneously, thereby changing the position of the plug 435 within the sliding groove 411.

[0025] Referring to FIG. 8, in this embodiment, the head portion 10 includes a first motor 11 and the vice massage portion 2 includes a third motor 51. Both the first motor 11 and the third motor 51 are capable of generating vibrations. The first motor 11 and the third motor 51 are controlled independently.

[0026] The massage head 30 has a sliding frequency A within the movement space 17. The sliding frequency A refers to the number of times the massage head 30 slides back and forth within the movement space 17 in one minute. The value range of A is 1 to 500 times. The sliding frequency A of the massage head 30 can be adjusted through a control button 11 (as shown in FIG.8).

[0027] In an exemplary embodiment of the present disclosure, a length of the vice massage portion 2 is shorter than that of the main massage portion 1, but the length relationship and / or length ratio between the main massage portion 1 and the vice massage portion 2 can be adjusted.

[0028] In this embodiment, the tail end of the shell 90 is provided with a charging port. The charging port is used to supply power to the driving member 13 and the circuit board 15. It can be understood that the power source of the massage module 100 can be an internal rechargeable battery or direct external power supply.

[0029] In this embodiment, the main massage portion 1, including head portion 10 and massage head 30, together with the vice massage portion 2, can simultaneously massage three different areas of the hole-like portion, thereby providing a wider massage area.

[0030] In the present disclosure, the size that can be inserted into the hole-like portion to be massaged of the human body is limited, in such situation, an additional movement space 17 is provided in the insertable part of the main massage portion 1, and also an additional massage structure that can provide additional stimulation can be arranged within this movement space 17 to enrich the massage experience. Moreover, the size of the movement space 17 is required to be designed under consideration of requirements such as a design size requirement of the insertable part, the stability requirements of the structure forming the moving space and the anti-stall requirements of the massage head, etc.. Through experiments, it is found that a distance L between two opposite end points of the moving space in the insertion direction X is preferably not less than 10 mm, reference data is 10mm to 200 mm, and the width W is preferably not less than 3 mm, reference data is 3mm to 65mm .

[0031] A gap 9135 is formed between cover layer 75 corresponding to an inner surface 932 of each of the two support arms 93 and the most outstanding outer surface 301 of a center of the massage head 30, thereby the massage head 30 does not contact the corresponding cover layer 75. The width of the gap 9135 is defined as M. As the dimensional constraints of the movement space 17, increasing the movement frequency and vibration intensity of the massage member 30 may cause slight displacements. Therefore, the width between the massage member 30 and the inner sidewall 242 must be carefully considered. Experimental results indicate that the width M is preferably not greater than 30 mm.<Second Embodiment>
