It will be apparent to those skilled in the art that variations of these specific details are possible while still achieving the results of the present invention.Exemplary illustrative embodiments of the invention should be interpreted as example(s) and not in a limiting sense. The relationship between different arms where they are located, their composition(s), their function, and sometimes their size relative to the desired function of the invention are not important.< Embodiment>Referring to FIGS. 1 to 12, there is shown a massage module 100 of the first embodiment of the present disclosure. The massage module 100 may be inserted into a human body to provide multiple stimuli to the user. The massage module 100 comprises a main massage section 1, the major part of which is introduced into the human body, for example a vagina, an auxiliary massage section 2 extending from the main massage section 1, a massage head 30 arranged in the main massage section 1, a drive device 60 for controlling the main massage section and / or other massage functions of the massage module 100, and a shell 90 for accommodating functional elements, such as the drive device 60 of the massage module 100.In an exemplary embodiment of the present disclosure, the length of the auxiliary massage portion 2 is shorter than that of the main massage portion 1.The main massage section 1 comprises a head section 10, a connecting section 20 and a handle 50. The head section 10 is configured such that it can be inserted into the vagina along an insertion direction X in order to provide a first stimulus for a first region of the vagina. The first stimulus may be, for example, a stimulation sensation generated by at least one of the following methods: friction, knocking, or vibration applied to the object to be touched. In an exemplary embodiment, the frictional movement generated by the insertion or extraction from the body forms the first stimulus. The connecting portion 20 connects the head portion 10 and the handle 50, and the connecting portion 20 includes an undermassage portion 21 configured to impart a second stimulus to the object to be touched. The massage head 30 corresponds to the undermassage portion 21 and reciprocates and linearly with respect to the main massage portion 1 under the control of the driving device 60. Referring also to FIG. 4, when the massage head 30 is inserted into the human body, the undermassage portion 21 is also inserted into the human body and then gives a second stimulus to the body, the second stimulus being generated by the linear movement of the massage head 30.The handle 50 includes a handle housing 91 and a plurality of control elements disposed therein. The driving device 60 is correspondingly accommodated in a cavity 911 (as shown in FIG. 5 ) defined by the handle housing 91. In an exemplary embodiment of the present disclosure, the handle housing 91 is a part of the shell 90 and is integrally molded with other parts of the shell 90. A through hole 912 (as shown in FIG. 2 ) is defined in a wall of the handle housing 91 facing the connecting portion 20. A transmission function member of the driving device 60 is connected to the massage head 30 via the through hole 912, whereby the driving device 60 drives the massage head 30 to move. The shell 90 comprises two support arms 93 projecting from two opposite edges of an upper end of the handle housing 91 along the longitudinal direction of the main massage section 1. The longitudinal direction is parallel to the insertion direction X. The two support arms 93 are arranged at a distance. A cavity 931 is defined between the two support arms 93. The cavity 931 is also formed by a recess that 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. Each of the first opening 9311 and the second opening 9313 communicates with the cavity 931 and connects the cavity 931 inside the shell 90 to an external surrounding space outside the shell 90. In some exemplary embodiments of the present disclosure, the cavity 931 may be, for example, a recess formed in the shell 90 by being pressed inward in the thickness direction of the shell 90 without penetrating through the shell 90, and the recess includes side walls defined by the two support arms 93, a bottom wall (not denoted) defined by the remaining shell, and an opening (e.g., the first opening 9311) communicating with the cavity 931.The massage head 30 is accommodated in the cavity 931 and can linearly reciprocate with respect to the main massage portion 1 under the control of the driving device 60, and at least a portion of a massage surface 35 of the massage head 30 can protrude from the shell 90 via at least one of the first openings 9311 and 9313. When the massage head 30 performs the linear reciprocating motion in the longitudinal direction, the massage surface 35 repeatedly applies pressure or stimulation to various positions of a certain area of the touched object, following the motions of the massage head 30.A gap 9315 is formed between the inner wall of the two support arms 93 and the outer wall of the massage head 30, whereby the massage head 30 does not contact the inner side walls of the two support arms 93.Referring to FIGS. 6 and 7, a cover 70 made of flexible material having elasticity covers the outer surfaces of the shell 90 except for the first opening 9311 and the second opening 9313, thereby connecting the first opening 9311 and the second opening 9313 to an exterior outside the shell 90. In some example embodiments of the present disclosure, the side of the cover 70 near the head portion 10 forms a moving space 17 defined by the cavity 931. The moving space 17 is a long arc-shaped hole. The massage head 30 is installed inside the moving space 17 and can reciprocate with respect to the shell 90. In this embodiment, the cover 70 completely covers the two support arms 93, but does not cover the top and bottom of the cavity 931, thereby coinciding the moving space 17 and the cavity 931.The cover 70 covers the main massage section 1, the massage head 30, and the auxiliary massage section 2 and serves to protect from water. The shell 90 is made of solid material, and the cover 70 is provided with a first cover 71 and a second cover 73. The second cover 73 is telescopically mounted within the cavity 931 and covers the articles in the cavity 931. The first cover 71 is configured to cover the massage module 100 until the objects in the cavity 931 are covered. The sliding movement of the massage head 30 drives the second cover 73 to telescope 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. One end of the second cover 73 is fixed to the handle housing 91 of the shell 90, and covers the extension rod 45 and the massage head 30. The other end of the second cover 73 is connected to the lower surface of the head portion 10. The second cover 73 is a foldable structure. In addition, when the massage head 30 moves in the first direction X of the shell 90 from the handle 50 to the head portion 10, the portion of the second cover 73 near the head portion 10 is compressed while the portion far from the head portion 10 is expanded. When the massage head 30 moves from the head portion 10 to the handle 50, the portion of the second cover 73 is largely compressed by the head portion 10 while the portion near the head portion 10 is expanded to move telescopically following the massage head 30.Referring to FIG. 8, the inside of the tray 90 forms various brackets protruding with respect to the inner wall of the tray 90, and the brackets are configured to fix the positions of the driving device 60, a circuit board 15, and others. The shell 90 is made of a hard material to improve support stability, increase durability, and extend the life of the massage module 100. The rear end of the shell remote from the head portion 10 is provided with a control member 11. The control element 11 is directly connected to the printed circuit board 15 and serves for controlling the massage module 100. It will be understood that the preferred position of the control member 11 is at the rear end of the massage module 100 to avoid being far from the battery, thereby reducing power transfer losses. It will be understood that the positions of the control member 11 are adjustable or may be replaced by a remote device or electronic product for control.Moreover, the shell 90 is made of a first material, the massage head 30 is made of a second material, and the cover 70 is made of a third material. The elasticity of the first material is less than that of the second material, and the elasticity of the third material is greater than that of the second material.Referring to FIGS. 2, 5, 8, and 9, the driving device 60 is installed in the cavity 911 of the shell 90. The driving device 60 includes a driving member 13, the circuit board 15, and a transmission mechanism 40. The sliding of the massage head 30 in the cavity 931 is performed by the coordinate between the transmission mechanism 40 and the driving member 13.The driving member 13 is fixedly installed in the cavity 911, and an elongated rotating shaft 131 extends from one end of the driving member 13 and is configured to install the transmission mechanism 40.The transmission mechanism 40 includes a screw 41, a slide block 43, and the extension rod 45. The rotation shaft 131 is inserted into one end of the perforation 413 and extends through the other end of the perforation 413, so that the screw 41 is fitted on the rotation shaft 131. The rotating shaft 131 continues to rotate, driven by the driving member 13, while driving the screw 41 to rotate. The slide block 43 is movably slid on the screw 41. One end of the extension rod 45 is connected to the slide block 43 and the other end extends through the through hole 912 toward the cavity 931 until it is connected to the massage head 30. In some exemplary embodiments of the present disclosure, the extension rod 45 and the bolt 41 are arranged parallel to each other and spaced apart.Referring to FIGS. 9 and 10, the screw 41 is a long and hollow cylindrical tube having a circular cross section. The screw 41 forms a spiral sliding groove 411 along its length. The rotating shaft 131 continues to rotate, driven by the driving member 13, while driving the screw 41 to rotate. At this time, the slide block 43 may move forward along the slide groove 411 from the end of the screw 41 located near the driving member 13 toward the end of the screw 41 far away from the driving member 13, or may move rearward along the slide groove 411 from the end of the screw 41 located near the driving member 13 toward the end of the screw 41 far away from the driving member 13, so that the slide block 43 reciprocates with respect to the screw 41 through the slide groove 411. The slide groove 411 is composed of a plurality of inclined grooves 4111. The adjacent two inclined grooves 4111 are V-shaped, and the two separate inclined grooves 4111 are parallel to each other, so that the adjacent three inclined grooves 4111 have an inclined N-shape. It is understood that the specific structure of the slide groove 411 can be designed according to actual requirements.Referring to FIGS. 9, 11 and 12, the slide block 43 is rectangular and includes a first portion 431 and a second portion 433 extending from and protruding from the first portion 431. The first portion 431 is connected to the bolt 41 and the second portion 433 is connected to the extension rod 45. The first portion 431 and the second portion 433 are integrally formed structures. The center of the first portion 431 defines a first through hole 4315 that extends longitudinally through the first portion 431. The screw 41 is inserted into the first through hole 4315, so that the slide block 43 is fitted on the screw 41. The top of the first portion 431 far from the second portion 433 defines a second through hole 4317 and the second through hole 4317 is connected to the first through hole 4315. A restriction block 4313 and a plug 435 are installed in the second through hole 4317. The restriction block 4313 contacts the plug 435, whereby the restriction block 4313 prevents the plug 435 from moving in the second through hole 4317. One portion of the plug 435 is accommodated in the second through hole 4317 and contacts the slide block 43. the other portion of the plug 435 extends through the second through hole 4315 to the first through hole 4315 and contacts the slide groove 411.The plug 435 includes a cylindrical rotating end 4351 that can rotate in the second through hole 4317 and an arc-shaped sliding end 4353. The rotating end 4351 and the sliding end 4353 are integrally formed structures. The slide end 4353 is directly locked in the slide groove 411. The radians of the sliding end 4353 and the sliding groove 411 are the same, i.e., the sliding end 4353 is fully fitted to the inner wall of the sliding groove 411. The two sides of the first portion 431 extend along the width direction and form a guide vane 4311. The inner wall of the shell 90 extends inwardly to form a pair of projections at a distance. A slide rail 913 is formed between the two protrusions. The upper wall and the lower wall of the slide rail 913 are connected to the guide vane 4311, so that the upper wall and the lower wall restrict the movement of the guide vane 4311 upward and downward, and thus the slide block 43 cannot move upward and downward with respect to the shell 90.The center of the second portion 433 defines a third through hole 4331, and the opening of the third through hole 4331 is the same as that of the first through hole 431. One end of the extension rod 45 is directly inserted into the third through hole 4331 to connect to the slide block 43. The extension rod 45 and the screw 41 are arranged parallel to each other and spaced apart.Referring to FIG. 9, the massage head 30 is T-shaped and includes a raised portion 31 and a connecting portion 33 extending from the raised portion 31. The connecting portion 33 is perpendicular to the raised portion 31, and the connecting portion 33 is fixedly connected to the extension rod 45. Two ends of the raised portion 31 protrude from the shell 90 through the hollow portion, i.e., the two ends of the raised portion 31 protrude from the two support arms 93. Two ends of the raised portion 31 form at least one opening and fixedly install a second motor 311. The second motor 311 is a vibration motor. The second motor 311 may vibrate by operating the control member 11. By cooperation of the driving device 60 and the second motor 311, the massage head 30 can generate a vibration effect during sliding, thereby improving the massage experience for users. It is understood that the vibration speed of the second motor 311 can be controlled by the controller 11. It is understood that the driving device 60 and the second motor 311 are independent structures, which means that the massage head 30 can only slide or generate only vibrations or generate vibrations during sliding.It is understood that the massage head 30 can also be accommodated in the movement space 17 and does not protrude from the shell 90. At this time, a portion of the second region of the vagina is inserted into the moving space 17 to come into contact with the massage head 30. When the massage head 30 reciprocates in the moving space 17 with respect to the shell 90, the massage head 30 massages the second region of the vagina.In other embodiments, the both ends of the massage head 30 are projected from the both openings of the support arms 93, respectively, to project from the shell 90. The second cover 73 wraps around the massage head 30, and the second cover 73 is made of a flexible material having elasticity, whereby the second cover 73 that wraps around the ends of the massage head 30 protrudes. In addition, when the massage head 30 reciprocates with respect to the cup 90 below the second cover 73, the second cover 73 does not prevent the massage head 30 from moving.Referring to Figs. 9-12, the principle of sliding the massage head 30 within the moving space 17 is as follows.The user operates the control member 11 to drive the driving member 13. The driving member 13 drives the rotating shaft 131 to rotate it clockwise or counter-clockwise, and the rotating shaft 131 drives the screw 41 to rotate it. As the screw 41 rotates, the side wall of a first inclined slide 4111a pushes out the sliding end 4353 of the plug 435, so that the sliding end 4353 slowly moves toward a second inclined slide 4111b, thus changing the position in the sliding groove 411 of the plug 435. The guide vane 4311 is restricted by the slide rail 913 and cannot move vertically, so that the plug 435 can slide the bolt 41 only horizontally along the bolt 41. The sliding of the sliding block 43 drives the extension rod 45 horizontally, whereby the extension rod 45 slides the massage head 30. When the slide end 4353 of the plug 435 rotates from the first inclined slide 4111a to the last inclined slide 4111n, the plug 435 returns to the first inclined slide along the inclined slide 411 on the other side of the slide groove 411 due to the constant rotation direction of the rotation shaft 131. The slide block 43 retracts the extension rod 45, whereby the massage head 30 slides reciprocally or performs reciprocating linear movements. It is understood that the sliding speed of the massage head 30 can be controlled and that its sliding speed depends on the rotational speed of the rotary shaft 131.In addition, the transmission mechanism 40 may be driven by an externally applied force to rotate the plug 435, thereby changing the position of the plug 435 within the slide groove 411.In addition, the plug 435 and the screw 41 can rotate simultaneously, thereby changing the position of the plug 435 within the slide groove 411.Referring to FIG. 8, in this embodiment, the head portion 10 includes a first motor 11 and the auxiliary massage portion 50 includes a third motor 51. both the first motor 11 and the third motor 51 can generate vibrations and thereby drive the head portion 10 and the auxiliary massage portion 50 to generate vibrations or vibrations at multiple angles. It is understood that the first motor 11 and the third motor 51 are controlled independently of each other. It is also understood that the number of the first motor 11 and the third motor 51 is not limited, and may be zero, one, or a multiple.In this embodiment, the rear end of the tray 90 is provided with a charging port. The charging terminal is used to supply power to the driving member 13 and the circuit board 15. It will be appreciated that the power source of massage module 100 may be an internal battery or a direct external power supply.In this embodiment, the cover 70 completely covers the opposite sides of the two support arms 93, thereby forming the moving space 17 that overlaps with the cavity 931. The massage head 30 is slidable in the cavity 931. The main massage section 1, including head section 10 and massage head 30, can massage three different areas of the vagina simultaneously together with the auxiliary massage section 2 and thus provide a wide massage area. Among other things, massage head 30 may slide back and forth to massage by drive device 60. The reciprocating massage mode of the stimulation portion, in combination with the vibration effect of the second motor, provides a better massage experience and is more practical.< Embodiment>Next, a description will be given of a second embodiment. For simplicity, parts identical to those of the previous first embodiment in FIG. are given the same reference numerals. Figures 1 to 12 are identified by identical reference numerals and will not be described again for brevity. This embodiment is different in the structure of the second cover 73 a.Referring to FIGS. 1, 3 and 13, in this embodiment, the cavity 931 is formed between the two support arms 93, and has the first opening 9311 and the opposite second opening 9313. When the cover 70 covers the massage module 100 a, the cavity 931 defines the moving space 17 also having the first opening 9311 and the opposing second opening 9313. The massage head 30 is movably installed inside the moving space 17, and the both ends of the massage head 30 extend and lie outside the shell 90 through the first opening 9311 and the second opening 9313.The first cover 71 covers the handle housing 91 and the support arms 93. The second cover 73 acovers the massage head 30 and the extension rod 45. one end of the second cover 73 ais connected to the handle housing 91, and the other end is not connected to the lower surface of the head portion 10.The second cover 73 ais a folded structure.
