[0032] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element and integrated with it, or there may be intermediate elements present at the same time. The terms "installation", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this technology belongs. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0034] The present invention specifically provides an embodiment of a sperm extraction device. See Figure 1 and Figure 2, including a movable cylinder 1 that can reciprocate; a rotatable inner cylinder 2 is arranged inside the movable cylinder 1, and at least one end of the inner cylinder 2 is open; a telescopic drive assembly is arranged on the side of the movable cylinder 1 and drives the movable cylinder 1 to reciprocate; a rotary drive assembly is also arranged on the side of the movable cylinder 1 and drives the inner cylinder 2 to rotate relative to the movable cylinder 1; a flexible cylinder 36 is arranged inside the inner cylinder 2, and at least one end of the inner cylinder 2 is open; the sperm extraction device further includes a sound structure, the sound structure is arranged outside the movable cylinder 1 and is relatively stationary with respect to the movable cylinder 1 and the inner cylinder 2, the sound structure includes a micro speaker 23 and a plurality of sound outlet holes 24 communicating with the outside, the plurality of sound outlet holes 24 are arranged around the inner cylinder 2, and the central axis formed by the arrangement of the plurality of sound outlet holes 24 coincides with the axis of the inner cylinder 2, and the sound wave generated by the micro speaker 23 is transmitted out through the sound outlet holes 24. The telescopic drive assembly drives the movable cylinder 1 to reciprocate. Since the inner cylinder 2 is arranged on the movable cylinder 1, when the movable cylinder 1 reciprocates, it will drive the inner cylinder 2 and the flexible cylinder 36 inside the inner cylinder 2 to reciprocate. The rotary drive assembly drives the inner cylinder 2 to rotate relative to the movable cylinder 1, and the inner cylinder 2 can also drive the flexible cylinder 36 inside it to rotate together, so as to realize that the flexible cylinder 36 has both telescopic and rotary functions. Through the telescoping and rotation of the flexible cylinder 36, it can perform all-round and more diverse massages when the user extracts sperm, improving the user's experience and being more conducive to promoting ejaculation. The telescopic drive assembly is arranged on the side of the inner cylinder 2, avoiding the arrangement of the telescopic drive assembly and the inner cylinder 2 in the length direction, effectively reducing the telescopic stroke of the telescopic drive assembly, improving the stability of the movement, and saving the space of the sperm extraction device in the length direction; by arranging a sound structure in the sperm extraction device, music or sounds can be played when the user uses it to relieve the user's mood and ejaculate smoothly. In addition, since the sound structure is arranged outside the movable cylinder 1 and is relatively stationary with respect to the movable cylinder 1 and the inner cylinder 2, it effectively avoids the interference of the movement of the movable cylinder 1 and the inner cylinder 2 on the micro speaker 23 and avoids pulling the wires of the micro speaker 23; and since the plurality of sound outlet holes 24 are arranged around the inner cylinder 2, and the central axis formed by the arrangement of the plurality of sound outlet holes 24 coincides with the axis of the inner cylinder 2 (the so-called "coincidence" here can be considered as complete coincidence or coincidence within an error range), through this axis coincidence structure, the sound wave passing through the sound outlet holes 24 by the micro speaker 23 can be propagated in the axial direction and directly applied to the genitals inside the flexible cylinder 36, which can enhance the effect and assist ejaculation. By providing at least one open end on the inner cylinder 2 and the flexible cylinder 36, a port for the user's genitals to insert is provided. In this embodiment, the flexible cylinder 36 is arranged in the inner cylinder 2 and reciprocates and rotates with the inner cylinder 2. The flexible cylinder 36 is used for inserting the male genitals and massaging the male genitals to ejaculate. Since the sperm extraction device can reciprocate and rotate for all-round massage, the user's experience is better and the effect of promoting ejaculation is better.In addition, the material of the flexible cylinder 36 can be silica gel.

[0035] In a preferred embodiment, referring to Figure 1 , both ends of the moving cylinder 1, the inner cylinder 2, and the flexible cylinder 36 are in an open state. On the basis that the telescopic drive assembly and the rotary drive assembly are arranged on the side of the moving cylinder 1 or the inner cylinder 2, it is allowed that both ends of the moving cylinder 1, the inner cylinder 2, and the flexible cylinder 36 are open, which is convenient for cleaning the flexible cylinder 36 and is more hygienic.

[0036] In a preferred embodiment, referring to Figure 2 , the sperm collection device further includes an inner housing 3, and the moving cylinder 1, the inner cylinder 2, the flexible cylinder 36, and the sound structure are all arranged in the inner housing 3; the inner housing 3 includes a first end face 301 and a second end face 302, and through holes are respectively arranged on the first end face 301 and / or the second end face 302. The through hole on the first end face 301 is used to expose the open end of the flexible cylinder 36. Specifically, when the flexible cylinder 36 has one open end, the through hole on the first end face 301 is used to expose the open end of the flexible cylinder 36. When the flexible cylinder 36 has two open ends, a through hole is also arranged on the second end face 302 to expose the open end of the other end of the flexible cylinder 36; a plurality of sound holes 24 are arranged on the second end face 302 of the inner housing 3, and an annular conduction cavity 25 is arranged inside the second end face 302 of the inner housing. The conduction cavity 25 is communicated with the plurality of sound holes 24, and the micro speaker 23 is arranged in the conduction cavity 25. Specifically, the first end face 301 of the inner housing 3 is the side for the user's genitals to insert, and the second end face 302 is the opposite face of the first end face 301; by arranging the conduction cavity 25, internal sound wave leakage can be reduced, preventing sound waves from overflowing from non-target directions, and at the same time blocking the noise interference generated during the operation of the telescopic drive assembly and the rotary drive assembly to a certain extent, effectively improving the output sound quality; the plurality of sound holes 24 are arranged in an annular array around the flexible cylinder 36 on the second end face 302 of the inner housing 3, which can make the output sound uniform. In addition, the sperm collection device in the prior art does not have the function of playing music. Since the sperm collection device itself is small and the internal structure is compact, it is usually not convenient for the installation of the sound structure; in this embodiment, by arranging the conduction cavity 25 inside the second end face 302 of the inner housing 3 and arranging the micro speaker 23 in the conduction cavity 25, the bottom space of the inner housing 3 can be effectively utilized, not only ensuring the sound effect, but also effectively utilizing the installation space, avoiding interference with the telescopic drive assembly and the rotary drive assembly, and ensuring that the sperm collection device still has the characteristics of small volume and compact structure.

[0037] In a preferred embodiment, referring to Figure 2, an assembly groove is provided on the surface of the conduction cavity 25 facing away from the sound outlet hole 24, a shock-absorbing layer 27 is provided in the assembly groove, the micro speaker 23 is connected to the shock-absorbing layer 27, and the distance between the sound-emitting surface of the micro speaker 23 and the sound outlet hole 24 is 5 mm - 10 mm. By providing the shock-absorbing layer 27, vibration interference to the micro speaker 23 generated by the telescopic drive mechanism during operation can be avoided; in addition, making the distance (which can be understood as the vertical distance) between the sound-emitting surface of the micro speaker 23 and the sound outlet hole 24 be 5 mm - 10 mm can shorten the sound wave transmission path, reduce loss, control the back pressure of the diaphragm, improve efficiency, and can also meet the compact space layout, enhance the anti-interference ability, that is, avoid the friction between the diaphragm and the edge of the sound outlet hole 24 caused by too close distance, resulting in noise or damage, and improve the service life.

[0038] In a preferred embodiment, refer to Figure 2 , a sound-absorbing cotton layer 28 is provided on the cavity wall surface of the conduction cavity 25 where the sound outlet hole 24 is not provided. By providing the sound-absorbing cotton layer 28 to absorb the noise generated during the movement of the telescopic drive assembly and the rotary drive assembly, it is ensured that the sound transmitted from the micro speaker 23 through the sound outlet hole 24 is pure and has good sound effects.

[0039] In a preferred embodiment, a waterproof and breathable membrane (not shown in the figure) covering the sound outlet hole 24 is provided on the inner surface of the second end face 302 of the inner shell at the position of the sound outlet hole 24, and the pore diameter of the waterproof and breathable membrane is 0.1 μm - 0.5 μm. By providing the waterproof and breathable membrane and setting the pore diameter of the waterproof and breathable membrane, efficient waterproofing, dustproofing, and antibacterial can be achieved through a physical mechanism, and sufficient air permeability and low air resistance can be ensured.

[0040] In a preferred embodiment, refer to Figure 2, the sperm extraction device further includes a first control module 29, which is arranged on the side wall inside the inner shell 3. The first driving mechanism 5 in the rotation driving assembly, the second driving mechanism 9 in the telescopic driving assembly, and the micro speaker 23 are respectively electrically connected to the first control module 29. The first control module 29 controls the playing rhythm of the micro speaker 23 to be synchronized with the moving speed of the moving cylinder 1 and the inner sleeve 2. Specifically, the first control module 29 can receive the operating parameters of the first driving mechanism 5 and the second driving mechanism 9, thereby judging the rhythm of the music or sound played by the micro speaker 23 to match the movement of the moving cylinder 1 and the inner sleeve 2, so as to enhance the auditory feedback during the user's use and accelerate the sperm ejaculation process. When the user wears a wearable device (such as a bracelet), the wearable device can be in signal communication with the first control module 29. The signal communication method is the prior art, such as Bluetooth connection, etc. The parameters such as the user's heart rate and emotion detected by the wearable device are sent to the first control module 29, and the first control module 29 can control the playing of music matching the user's current state. For example, when the customer has a fast heart rate and is nervous, some soothing music is played to relieve the tension.

[0041] In a preferred embodiment, referring to Figure 3 , the rotation driving assembly includes a first gear 7, a second gear 8, and a first driving mechanism 5 that outputs rotational motion. The first driving mechanism 5 can be a motor that outputs rotational motion or an electric motor that outputs rotational motion; the first driving mechanism 5 is connected to the outer wall of the moving cylinder 1, that is, a first mounting seat 6 is provided on the outer side wall of the moving cylinder 1, a mounting groove is provided on the first mounting seat 6, the first driving mechanism 5 is installed in the mounting groove of the first mounting seat 6, and the output shaft of the first driving mechanism 5 passes through one side wall of the mounting groove to be connected to the first gear 7. A notch is provided on one side wall of the mounting groove of the first mounting seat 6, and the output shaft of the first driving mechanism 5 can pass through the notch; the first driving mechanism 5 is connected to the first gear 7, and a second gear 8 is provided around the inner sleeve 2. The first gear 7 meshes with the second gear 8. By driving the first gear 7 to rotate through the first driving mechanism 5, the first gear 7 drives the second gear 8 to rotate, and then drives the inner sleeve 2 to rotate. On the basis of arranging the rotation driving assembly and the telescopic driving assembly on the side of the moving cylinder 1, the telescopic driving assembly and the rotation driving assembly can be directly arranged and directly act on the parts they drive, reducing the intermediate transmission parts, with a simpler structure and more accurate transmission.

[0042] In a preferred embodiment, the second gear 8 can be sleeved on the outer side wall of the inner sleeve 2 through its inner hole; or a circular flange can be provided at one end port of the inner sleeve 2, and meshing teeth are provided on the edge of the circular flange. The second gear 8 is formed by the meshing teeth and the circular flange, referring to Figure 3 .

[0043] In a preferred embodiment, referring to Figure 3 , the telescopic driving assembly includes a second driving mechanism 9 that outputs linear reciprocating motion, such as a linear motor or an electric cylinder, etc. The output shaft of the second driving mechanism 9 is connected to the moving cylinder 1, and the reciprocating motion of the output shaft of the second driving mechanism 9 drives the moving cylinder 1 to perform reciprocating motion; alternatively, the telescopic driving assembly includes a screw transmission structure, a guiding structure, and a second driving mechanism 9 that outputs rotational motion; the second driving mechanism 9 is connected to the moving cylinder 1 through the screw transmission structure, and the second driving mechanism 9 outputs rotational motion to drive the moving cylinder 1 to perform reciprocating motion through the screw transmission structure; the guiding structure is guidingly connected to the moving cylinder 1, and under the guidance of the guiding structure, the moving cylinder 1 performs reciprocating motion along a straight line. Among them, the screw transmission structure has various structures, as long as it can transform the rotational motion output by the second driving mechanism 9 into linear motion. For example, referring to Figure 1 and Figure 3 , the screw transmission structure includes a screw rod 11 connected to the second driving mechanism 9 and a threaded sleeve 10 with an internal threaded hole connected to the side wall of the moving cylinder 1. The second driving mechanism 9 is connected to the bottom surface of the inner housing 3, and the threaded sleeve 10 is sleeved on the screw rod 11 through thread fitting. By driving the screw rod 11 to rotate forward and backward by the second driving mechanism 9, the threaded sleeve 10 performs reciprocating motion along the axial direction of the screw rod 11, thereby driving the moving cylinder 1, the inner sleeve 2, and the flexible cylinder 36 to perform reciprocating motion. The threaded sleeve 10 is connected to the moving cylinder 1 through a connecting plate 12; referring to Figure 4 , the screw transmission structure can also be a threaded sleeve 10 that does not perform reciprocating motion with the moving cylinder 1 and a screw rod 11 connected to the moving cylinder 1 and performing reciprocating motion with the moving cylinder 1. The second driving mechanism 9 is connected to the moving cylinder 1 and performs reciprocating motion with the moving cylinder 1, and the second driving mechanism 9 is connected to the screw rod 11, so that the screw rod 11 is indirectly connected to the moving cylinder 1. The threaded sleeve 10 is connected to the inner housing 3 of the sperm extraction device through a connecting plate 12, and the threaded sleeve 10 is sleeved on the screw rod 11 through thread connection. By rotating the second driving mechanism 9 forward and backward to drive the screw rod 11 to rotate, due to the thread fit between the screw rod 11 and the threaded sleeve 10, the screw rod 11 can drive the second driving mechanism 9 and the moving cylinder 1 to perform reciprocating motion while rotating relative to the threaded sleeve 10, thereby driving the inner sleeve 2 and the flexible cylinder 36 to perform reciprocating motion through the moving cylinder 1; referring to Figure 5, the screw drive structure may also include a threaded sleeve with internal threads connected to the second drive mechanism 9 and a screw 11 connected to the moving cylinder 1 through a connecting plate 12. The screw 11 is spaced from the moving cylinder 1 through the connecting plate 12 to avoid interference of the moving cylinder 1 with the connection between the screw 11 and the threaded sleeve. The second drive mechanism 9 is connected to the bottom surface of the inner housing 3. The second drive mechanism 9 drives the threaded sleeve to rotate forward and backward, and the screw 11 moves along its axial direction through the threaded engagement with the threaded sleeve, thereby driving the moving cylinder 1, the inner sleeve 2 and the flexible cylinder 36 to make reciprocating motions; see Figure 6 , the screw drive structure may also include a threaded sleeve 10 and a screw 11 threadedly connected to the threaded sleeve 10. The screw 11 is vertically connected to the bottom surface of the inner housing 3. The second drive mechanism 9 is connected to the moving cylinder 1. The second drive mechanism 9 is connected to the threaded sleeve 10 through a gear meshing connection structure. The threaded sleeve 10 is sleeved on the screw 11 through threaded engagement. The second drive mechanism 9 drives the threaded sleeve 10 to rotate forward and backward. The threaded sleeve 10 moves up and down through the threaded engagement with the screw 11 to drive the second drive mechanism 9 and the moving cylinder 1 to make reciprocating motions, thereby driving the inner sleeve 2 and the flexible cylinder 36 to make reciprocating motions; the above Figure 3-6 The thread on the screw 11 of the screw drive structure in the above is a one-way thread. When the moving cylinder 1 needs to make a reciprocating motion, the second drive mechanism 9 needs to output a forward and reverse motion to achieve it. Of course, the thread on the screw 11 can adopt a double helical groove 13, see Figure 7, the so-called double helical groove 13 includes an ascending helical groove and a descending helical groove. An annular sliding sleeve 14 is connected to the side wall of the moving cylinder 1 through a connecting plate 12. A guide pin is arranged in the inner hole of the sliding sleeve 14. The guide pin includes a connecting column 15 connected to the sliding sleeve 14 and an arc-shaped portion 16 extending into the double helical groove 13 on the screw rod 11. The arc-shaped portion 16 is connected to the connecting column 15, and the shape of the arc-shaped portion 16 is adapted to the double helical groove 13. The screw rod 11 is connected to the second driving mechanism 9. The screw rod 11 is driven by the second driving mechanism 9 to rotate unidirectionally, so as to cause the guide pin to continuously move in the double helical groove 13 of the screw rod 11, thereby driving the sliding sleeve 14 and the moving cylinder 1 to make reciprocating motions, and further driving the inner sleeve 2 and the flexible cylinder 36 to make reciprocating motions. It can be seen that by continuously driving the screw rod 11 to rotate unidirectionally by the second driving mechanism 9, the reciprocating motions of the moving cylinder 1, the inner sleeve 2, and the flexible cylinder 36 can be realized; the helix directions of the ascending helical groove and the descending helical groove are different, which can be understood as one being left-handed and the other being right-handed. They intersect with each other, and the top of the ascending helical groove is connected to the top of the descending helical groove, and the bottom of the ascending helical groove is connected to the bottom of the descending helical groove, which is convenient for the guide pin to enter the descending helical groove from the ascending helical groove or enter the ascending helical groove from the descending helical groove, ensuring that when the screw rod 11 rotates unidirectionally, the guide pin can effectively drive the reciprocating motions of the sliding sleeve 14, the moving cylinder 1, the inner sleeve 2, and the flexible cylinder 36.

[0044] In the preferred embodiment, referring to Figure 1 and Figure 3, the guiding structure includes a guiding rod 20 and a sliding sleeve 19; the sliding sleeve 19 is connected to the moving cylinder 1. One end of the guiding rod 20 is fixed, and the other end of the guiding rod 20 passes through a sliding hole provided on the sliding sleeve 19, and the sliding sleeve 19 reciprocates along the guiding rod 20. Additionally, the sperm extraction device further includes an outer cylinder 17. A first opening groove 18 is axially provided on the side wall of the outer cylinder 17. The sliding sleeve 19 is arranged on the side wall of the moving cylinder 1, and the guiding rod 20 is arranged on the side of the outer cylinder 17. Part of the sliding sleeve 19 passes through the first opening groove 18 on the outer cylinder 17 and then sleeves on the guiding rod 20. The moving cylinder 1 reciprocates to drive the sliding sleeve 19 to reciprocate relative to the first opening groove 18 and the guiding rod 20. Specifically, at least one end of the guiding rod 20 is connected to the bottom surface of the inner housing 3, that is, a second mounting seat 21 is provided on the bottom surface of the inner housing 3. An installation groove is provided on the second mounting seat 21, and the corresponding end of the guiding rod 20 is inserted into the installation groove of the second mounting seat 21; part of the sliding sleeve 19 passes through the first opening groove 18 on the outer cylinder 17 and then sleeves on the guiding rod 20. The moving cylinder 1 reciprocates to drive the sliding sleeve 19 to reciprocate relative to the first opening groove 18 and the guiding rod 20. The sliding sleeve 19 and the guiding rod 20 constitute the guiding structure. Such a guiding structure can have one or more groups, which is set according to actual needs. In this embodiment, two groups of such guiding structures are adopted, and the guiding is more stable. Through the cooperation of the sliding sleeve 19 with the guiding rod 20 and the first opening groove 18, it can be ensured that the moving cylinder 1 does not rotate but only reciprocates in the axial direction; and the first opening groove 18 provides a space for the sliding sleeve 19 to pass through. In addition, the outer cylinder 17 can also play a role in protecting the internal structure and preventing external sundries from entering the internal structure.

[0045] In a preferred embodiment, referring to Figure 1 and Figure 3 , the sperm extraction device further includes an outer cylinder 17. A second opening groove 22 is axially provided on the side wall of the outer cylinder 17. The rotation driving assembly further includes a first mounting seat 6 for mounting the first driving mechanism 5. The first mounting seat 6 is arranged on the moving cylinder 1. Part of the first mounting seat 6 passes through the second opening groove 22 on the outer cylinder 17. The moving cylinder 1 reciprocates to drive the first mounting seat 6 to reciprocate relative to the second opening groove 22. Specifically, the second opening groove 22 is mainly used to provide an installation space for the first mounting seat 6. A third opening groove 4 is also axially provided on the side wall of the outer cylinder 17. The third opening groove 4 is configured to allow part of the telescopic driving assembly to pass through. Specifically, when the thread transmission structure adopts Figure 1 , Figure 3 , Figure 5 and Figure 7 in the implementation manners, the third opening groove 4 is mainly used to provide a space for part of the connecting plate 12 in the telescopic driving assembly to pass through.
