Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a pregnancy aid for improving the physiological and psychological states of pregnancy assistance. Background Art

[0002] There is a conventional pregnancy aid including a piston tube, a plunger rod with a piston at the front end, and an outer sleeve tube. The front end of the plunger rod extends into the piston tube at the rear end of the piston tube, and the piston is in mating contact with the inner wall of the piston tube. The outer sleeve tube is sleeved outside the piston tube. A detachable semen collection funnel is connected to the front end of the piston tube. After the pregnancy aid is inserted into the vagina, pushing the piston rod can pump semen out from the front end of the piston tube to the cervix.

[0003] Another conventional pregnancy aid has an added vibration function. The vibration motor is arranged at a position on the pregnancy aid that is farther from the semen container and closer to the tail of the pregnancy aid. After the pregnancy aid is inserted into the vagina, the vibration is first started to stimulate the vagina, and then the piston rod is pushed to pump out semen.

[0004] However, in fact, users with a resistant psychology towards the pregnancy aid are often more resistant to the start and the process of inserting the pregnancy aid. And the existing design of this vibration-type pregnancy aid does not well consider the physiological and psychological states of users before and during the insertion. Summary of the Invention

[0005] The purpose of the present invention is to provide a pregnancy aid that can improve the physiological and psychological states of pregnancy assistance before and during the insertion.

[0006] The pregnancy aid provided by the present invention includes a piston and a piston tube that are in piston cooperation in a straight line direction. A sperm storage space and an ejection hole of the sperm storage space are provided at the front end of the piston tube; a vibration module; and a propulsion module. The propulsion module includes a propulsion member that can move in a straight line direction. The propulsion member is provided with a first cavity, and the vibration module is placed in the first cavity; the propulsion member can push the piston forward.

[0007] As can be seen from the above solution, the present invention combines the vibration module into the pregnancy aid. However, different from the existing vibration-type pregnancy aid, the vibration module of the present invention is combined at a position near the piston at the front part of the pregnancy aid. Since the position of the piston is close to the head position of the pregnancy aid, the vibration is better transmitted to the head of the pregnancy aid. Therefore, the user can be stimulated by the vibration of the head of the pregnancy aid before and during the insertion to relieve the resistant psychology, relax the body and mind, and moisten the vaginal environment, making the insertion of the pregnancy aid more comfortable and smooth. When the pregnancy aid is inserted in place, the user does not need complex stretching and pushing operations, and only needs to press a button to control the propulsion module to work to automatically pump out semen to complete pregnancy assistance. It can be seen that the pregnancy aid of the present invention can improve the physiological and psychological states of pregnancy assistance before and during the insertion, and is conducive to a smoother and easier pregnancy assistance process.

[0008] A further solution is that the piston is sleeved outside the propulsion member; or, it also includes an inner component, the piston is sleeved outside the inner component, and the propulsion member abuts against the inner component; the inner component is provided with a screw hole, and the screw hole is used for detachable connection with the screw of the pumping rod, the piston tube, the piston and the inner component can be disassembled synchronously, and when the piston tube is in the disassembled state, the screw hole is exposed.

[0009] As can be seen from the above, in the technical solution where the piston is mounted outside the propulsion member, the vibration of the propulsion member is more directly transmitted to the piston, and then better transmitted to the head of the fertility aid; while the solution where the piston module can be detached is convenient for the user to manually pump in semen, and the straight-line screw button of the pumping rod can be inserted and passed through the straight-line screw button hole and then rotated to reach the fastening state, and then the user can pull the pumping rod to pump semen from the outlet of the piston tube into A further solution is that the propulsion member includes a first piece; a first snap-fit structure group is arranged between the first piece and the piston, the first snap-fit structure group includes a first snap-fit structure arranged on the outer periphery of the first piece and a second snap-fit structure arranged on the inner periphery of the piston, one of the first snap-fit structure and the second snap-fit structure is a radial protrusion along the piston, and the other of the first snap-fit structure and the second snap-fit structure is a radial groove, and the first snap-fit structure and the second snap-fit structure cooperate to fix the relative position of the first piece and the piston in a linear direction.

[0010] As can be seen from the above, since the forward and backward movement of the piston is driven by the first piece, the setting of the first engaging structure group enables the piston and the first piece to maintain a good engaging relationship, especially relative fixation in the straight line direction. This setting can enable the piston and the first piece to maintain a connection state for a long time, effectively and stably, and the product is more durable.

[0011] A further solution is that a sealing rib is protruded from the outer periphery of the piston, and the sealing rib abuts against the inner wall surface of the piston tube; at least one set of engaging structure groups and the sealing rib are on the same plane perpendicular to the straight line direction.

[0012] As can be seen from the above, this arrangement can utilize the force generated by the abutment between the piston and the piston tube to prevent the first engaging structure and the second engaging structure from separating radially, further ensuring that the piston and the first member maintain a stable engaging relationship.

[0013] In a further solution, the vibration module includes an eccentric rotor; the piston is provided with a second cavity, and the first piece and the eccentric rotor are both located in the second cavity.

[0014] As can be seen from the above, under this setting, the eccentric rotor that generates vibration is located inside the piston, and the vibration is further effectively transmitted to the head of the fertility aid, achieving a better stimulation effect.

[0015] Another further solution is that the propulsion member includes a second part, the second part covers and combines with the first part in a linear direction to form a first cavity; the vibration module includes a first driving unit, and at least a part of the first driving unit is located inside the second part.

[0016] As can be seen from the above, the second part is first assembled. Subsequently, the vibration module is first installed in the first cavity, and then the first part is covered and fixed. This setting reduces the assembly difficulty of the propulsion member and the vibration module.

[0017] Another further solution is that the propulsion member further includes a third part; the propulsion module includes a second driving unit, a reciprocating lead screw, a moving part, and a guiding part; the reciprocating lead screw is arranged in a linear direction, and the second driving unit drives the reciprocating lead screw to rotate; the guiding part is fixedly arranged on the outer periphery of the reciprocating lead screw, the third part is arranged on the outer periphery of the guiding part and is slidably matched with the guiding part; the guiding part is provided with a guiding hole, the guiding hole extends in a linear direction and communicates between the reciprocating lead screw and the third part, and the guiding hole has a first inlet in the linear direction; the moving part is inserted into the guiding hole and is slidably matched with the guiding hole in the linear direction, one end of the moving part is matched with the third part, and the other end of the moving part is matched with the thread groove of the reciprocating lead screw.

[0018] As can be seen from the above, in this setting, the second driving unit only needs to rotate in one direction to drive the piston to move forward and backward, reducing the cost investment of the driving unit.

[0019] Another further solution is that the propulsion member further includes a connecting piece; the third part includes an installation opening penetrating inside and outside, and the connecting piece can be detachably installed in the installation opening from the outer periphery of the third part; the third part is provided with a concave first arc part, the connecting piece is provided with a concave second arc part, the first arc part and the second arc part are arranged oppositely and an axial hole is formed between the two; the third part is provided with a second inlet in the linear direction, and the first arc part, the second arc part and the second inlet are arranged in sequence in the linear direction; the moving part includes a shaft body, and the shaft body is matched with the axial hole.

[0020] As can be seen from the above, since both the guiding part and the third part need to be sleeved in a linear direction, and need to be sleeved on the reciprocating lead screw from the inside to the outside one by one, and the moving part extends in a direction perpendicular to the linear direction and straddles the reciprocating lead screw, the guiding part and the third part, which causes certain obstacles. This setting makes the assembly of the propulsion member have a certain installation difficulty. And the present invention combines a detachable connecting piece, and combines the second inlet provided on the third part and the first inlet provided on the guiding part. Both the first inlet and the second inlet are used for the moving part to enter in the linear direction. This setting enables the guiding part and the third part to be sleeved without being hindered by the moving part, and finally the connecting piece is installed to limit the moving part and enable the moving part to have a rotational freedom.

[0021] A further solution is that the guiding member is arranged around the reciprocating lead screw, and the outer peripheral surface of the guiding member cooperates with the inner peripheral surface of the third member; and / or, the inner periphery of the third member is provided with a rib protruding towards the reciprocating lead screw, and the rib extends in a straight line direction, and the rib cooperates with the guiding hole, and the first arc portion is arranged at the extending end of the rib.

[0022] As can be seen from the above, with this setting, it can be ensured that there is no relative rotation between the guiding member and the third member. Mainly, it can ensure that the moving member moves reciprocally in a straight line, ensuring the stability and effectiveness of the action.

[0023] A further solution is that it further includes a first housing, the first housing is connected to the piston tube and arranged in sequence along a straight line direction, and the first housing is sleeved outside the third member; it further includes a detection module and a detected member; the detected member is arranged on the third member, the detection module is arranged on the first housing, and the detection module includes at least two detection units arranged at intervals along a straight line direction; when the propulsion member is located at the first extreme position in the straight line direction, the detected member is within the detection range of one of the detection units; when the propulsion member is located at the second extreme position in the straight line direction, the detected member is within the detection range of another detection unit.

[0024] As can be seen from the above, with this setting, when the propulsion member moves forward and backward to the corresponding extreme positions, it can be sensed, and the start and stop of the motor of the propulsion module can be controlled according to the obtained corresponding sensing signals.

[0037] The first embodiment of the pregnancy aid Refer to Figure 1 , in the figure, the x-axis direction represents the linear direction of the present invention, which is also the length direction of the pregnancy aid, and is also the axial direction of the piston 12 and the piston tube 11 of the pregnancy aid. Additionally, Figure 1 the front part in the positive direction of the x-axis shown is the head of the pregnancy aid, Figure 1 the rear part in the positive direction of the x-axis shown is the tail of the pregnancy aid.

[0038] The pregnancy aid of this embodiment includes a piston module 1, a vibration module 2, a propulsion module 3, an outer sleeve assembly, a housing assembly, a battery 95, a circuit board 96, and a button 97.

[0039] Among them, the piston module 1 includes a piston 12 and a piston tube 11 that cooperate with the piston. The front end of the piston tube 11 is provided with a sperm storage space 110 and an ejection hole 1101 of the sperm storage space 110.

[0040] Among them, the vibration module 2 includes a first driving unit 21 and an eccentric rotor 22 driven to rotate by the first driving unit 21. The rotation axis of the eccentric rotor 22 coincides with the axis of the piston 12.

[0041] Among them, the propulsion module 3 mainly uses a telescopic gearbox, which includes a first driving unit 39, a reciprocating lead screw 38, a guide member 37, a sealing ring 36, a moving member 35, a connecting member 34, and a propulsion member that can reciprocate in the x-axis direction. The propulsion member includes a third member 33, a second member 32, and a first member 31.

[0042] Among them, the outer sleeve assembly includes a head sleeve 91 and a body sleeve 92, and the housing assembly includes a first housing 93 and a second housing 94.

[0043] Refer to Figure 1 and Figure 2, the second housing 94 actually includes two semi - shell structures divided by a base surface passing through the axis of the assistive device. The second housing 94 includes a cylindrical wall 941 and an end wall 942 at the tail of the assistive device. The first housing 93 is cylindrical. The first end of the first housing 93 and the cylindrical wall 941 of the second housing 94 are fixed by a snap connection. The second end of the first housing 93 is sleeved on the tail of the cylindrical wall of the piston tube 11. The external thread 119 ( Figure 3 as shown) of the tail of the cylindrical wall of the piston tube 11 is thread - fitted with the internal thread 939 at the second end of the first housing 93 for fixed connection. The second housing 94, the first housing 93, and the piston tube 11 are sequentially connected along the positive x - axis direction to form the complete housing body of the assistive device. The piston 12, the vibration module 2, the propulsion module 3, the battery 95, the circuit board 96, and the button 97, etc. are all arranged as internal structures within the housing body, and the outer sleeve assembly is sleeved outside the housing body.

[0044] Continue to refer to Figure 1 and Figure 2 , among which, the battery 95, the circuit board 96, the button 97, and the first driving unit 39 are all arranged within the second housing 94. The second housing 94 is also provided with a button hole 940 for the button 97 to pass through. The other structures of the propulsion module 3 except the first driving unit 39 are mainly arranged within the first housing 93. The piston 12 is arranged within the piston tube 11. The first part 31 and the vibration module 2 can move between the first housing 93 and the piston 12.

[0045] Refer to Figure 1 , Figure 3 and Figure 7 , the third part 3, the second part 2, and the first part 1 are sequentially connected and arranged in sequence along the positive x - axis direction. The first part 1 is fixedly connected to the piston 12. The front end of the first part 1 is provided with a disc 311. The disc 311 protrudes radially along the piston 12 towards the outer periphery of the disc 311. Correspondingly, in the x - axis direction, on one side of the disc 311, a second annular groove 313 is formed. The inner periphery of the second annular groove 313 is provided with a connecting post 3131 with a cross - shaped cross - section; in addition, on the outer periphery of the first part 1, a first annular groove 312 closer to the second part 32 than the second annular groove 313 is also provided. In addition, from the first annular groove 312 to the second annular groove 313, the outer peripheral surface of the first part 1 is set as an outward - convex arc surface that gradually narrows along the cross - section. Among them, the disc 311, the first annular groove 312, and the second annular groove 313 are all the first engaging structures arranged on the outer peripheral part of the first part 1 of the present invention. The disc 311 is a protrusion, and the first annular groove 312 and the second annular groove 313 are both grooves.

[0046] Continue Figure 1 , Figure 3 and Figure 7, In contrast, on the inner peripheral portion of the second chamber 1200 of the piston 12, a third annular groove 121, a second annular protrusion 123, and a first annular protrusion 122 are sequentially arranged along the negative x-axis direction. The third annular groove 121, the second annular protrusion 123, and the first annular protrusion 122 are all the second engaging structures of the present invention. The third annular groove 121 is a card slot, and both the second annular protrusion 123 and the first annular protrusion 122 are protrusions.

[0047] The piston 12 is sleeved outside the first member 31, that is, the first member 31 is installed in the second chamber 1200. The third annular groove 121 engages with the disc 311, the first annular protrusion 122 engages with the first annular groove 312, and the second annular protrusion 123 engages with the second annular groove 313. The first engaging structure and the second engaging structure constitute the first engaging structure group of the present invention. With the cooperation of multiple groups of first engaging structure groups, the first engaging structure and the second engaging structure cooperate to fix the relative position of the first member 31 and the piston in the x-axis direction.

[0048] Furthermore, two sealing rib strips 129 are convexly provided on the outer peripheral portion of the piston 12 at intervals along the x-axis direction. The sealing rib strips 129 are in contact with the inner wall surface of the piston tube 11. For details, refer to Figure 7 , the third annular groove 121, the disc 311, and one of the sealing rib strips 129 relatively close to the head of the pregnancy aid are all on the same plane L perpendicular to the x-axis direction. This setting can use the acting force generated by the contact and cooperation between the piston and the piston tube 11 to prevent the first engaging structure and the second engaging structure from separating radially, further ensuring the stable engagement relationship between the piston 12 and the first member 31.

[0049] Refer to Figure 1 , Figure 4 and Figure 7 , the second member 32 and the first member 31 are covered and formed a first chamber 300 along the x-axis direction; the first driving unit 21 is a motor, and at least a part of the first driving unit 21 is located inside the second member 32. The first member 31 and the eccentric rotor 22 are both located in the second chamber 1200. Under this setting, the second member 32 can be adhesively fixed and installed on the third member 33 by screwing inside the second member 32 first, and then the vibration module 2 and the first member 31 are installed. This setting optimizes the product assembly structure and reduces the assembly difficulty. Among them, preferably, in order to ensure the connection stability between the first member 31 and the second member 32, in other embodiments, the first member 31 and the second member 32 can be connected by threads.

[0050] Refer to Figure 1 , Figure 5 and Figure 6, the second driving unit 39 is a motor. Driven by the second driving unit 39, the reciprocating lead screw 38 can rotate around the axis of the piston 12 as the rotation center. The moving member 35 functions the same as a lead screw nut or a lead screw ball. Mainly, the moving member 35 pushes the third member 33 to move along the x-axis direction. However, since the reciprocating lead screw 38 is provided with two thread grooves 380 with opposite and interconnected spiral directions, the moving member 35 needs to have a rotational degree of freedom to complete the switching between the two spiral grooves 380.

[0051] Among them, it is necessary to make the third member 33 finally move accurately along the x-axis direction through the anti-rotation and limiting effects of the guiding member 37. The guiding member 37 is a sleeve member. The guiding member 37 is fixedly sleeved on the outer periphery of the reciprocating lead screw 38 and is fixed by its own flange part to the housing of the second driving unit 39 or is threadedly connected to the housing fixedly connected to the second driving unit 39; the guiding member 37 is provided with a guiding hole 370. The guiding hole 370 extends along the x-axis direction and communicates between the reciprocating lead screw 38 and the third member 33. The guiding hole 370 has a first inlet 3701 in the x-axis direction, and the first inlet 3701 opens towards the negative x-axis direction. In addition, the outer peripheral contour of the guiding member 37 is hexagonal prism-shaped.

[0052] The inner peripheral contour of the cylindrical wall of the third member 33 is hexagonal prism-shaped, and the cylindrical wall of the third member 33 is provided with a rib 332. The rib 332 protrudes towards the reciprocating lead screw 38 on its inner circumference and the rib 332 extends along the x-axis direction. Thus, when the third member 33 is sleeved on the outer periphery of the guiding member 37, the polygonal inner peripheral surface of the third member 33 cooperates with the polygonal outer peripheral surface of the guiding member 37, and the rib 332 is snapped into the guiding hole 370. Under this cooperation, the third member 33 and the guiding member 37 are slidably matched along the x-axis direction, and the third member 33 cannot rotate relative to the guiding member 37.

[0053] The cylindrical wall of the third member 33 includes an installation port 330 that penetrates between the inner and outer sides of the cylindrical wall along the radial direction of the piston 12. The cross section of the extending end of the rib 332 is set as a concave first arc portion 331. The axis of the first arc portion 331 is along the radial direction of the piston 12. The installation port 330 communicates to the axis position of the first arc portion 331 along its penetrating direction. In addition, the third member 33 is provided with a second inlet 3301 in the x-axis direction. The second inlet 3301 opens towards the negative x-axis direction, and the second inlet 3301 is opposite to the first arc portion 331. The connecting member 34 can be detachably installed in the installation port 330 from the outer periphery of the third member 33. The connecting member 34 is provided with a concave second arc portion 341. The first arc portion 331 and the second circular ring portion are arranged oppositely and an axial hole is formed between them. At this time, the first arc portion 331, the second arc portion 341 and the second inlet are arranged in sequence along the x-axis direction.

[0054] The opposite ends of the moving part 35 are respectively a shaft body 351 and a moving body 352. The moving body 352 includes two cones located on opposite sides of the axis of the shaft body 351, and the two cones can play a guiding role when switching the thread groove 380. The moving part 35 is inserted through the guiding hole 370 and is slidably matched with the guiding hole 370 along the x-axis direction. The shaft body 351 of the moving part 35 is rotationally matched with the shaft hole formed between the first arc part 331 and the second ring part on the third part 33. The moving body 352 of the moving part 35 is matched with the thread groove 380 of the reciprocating lead screw 38. The present invention provides a detachable connecting piece 34, and in combination with the second inlet 3301 provided on the third part 33 and the first inlet 3701 provided on the guiding piece 37, both the first inlet 3701 and the second inlet 3301 are used for the moving part 35 to enter along the x-axis direction. This setting enables the guiding piece 37 and the third part 33 to be sleeved without being hindered by the moving part 35, and finally the connecting piece 34 is installed to limit the moving part 35 and enable the moving part 35 to have a rotational degree of freedom.

[0055] See Figure 1 , the propulsion member further includes a sealing ring 36 sleeved outside the third part 33; the first housing 93 is sleeved outside the third part 33, and the sealing ring 36 abuts against the inner peripheral surface of the first housing 93. With this setting, the space where the driving unit is located and the space where the piston module is located are separated by the sealing ring 36, and the motor and the circuit are better protected.

[0056] See Figure 1 , the body sleeve 92 is sleeved outside the first housing 93 and the second housing 94 and is engaged. See Figure 7 , the head sleeve 91 is provided with an emission channel 911. The head sleeve 91 is sleeved outside the piston tube 11, and the emission channel 911 is communicated with the emission hole 1101. A second engaging structure group is provided between the head sleeve 91 and the piston tube 11. The second engaging structure group includes a third engaging structure 118 provided on the outer peripheral part of the piston tube 11 and a fourth engaging structure 918 provided on the inner peripheral part of the head sleeve 91. One of the third engaging structure 118 and the fourth engaging structure 918 is a protrusion along the radial direction of the piston, and the other of the third engaging structure 118 and the fourth engaging structure 918 is a groove along the radial direction. The third engaging structure 118 and the fourth engaging structure 918 cooperate to fix the relative position of the head sleeve 91 and the piston tube 11 in the x-axis direction. The setting of the head sleeve 91 makes the head of the fertility aid have a more skin-friendly and soft touch, and even when the vibration module works in a strong vibration mode, it can avoid causing pain, thereby ensuring a strong stimulation feeling but not causing discomfort and improving the use experience.

[0057] Mainly, the present invention keeps combining the vibration module 2 with the sperm injector. However, different from the existing vibratory sperm injectors, the vibration module 2 of the present invention is arranged inside the piston 12, and the piston 12 is very close to the head of the sperm injector. In this setting, the vibration is better transmitted to the head of the sperm injector. Therefore, before and during the insertion of the sperm injector, the user can be stimulated by the vibration of the head of the sperm injector to relieve the resistance psychology, relax the body and mind, and moisten the vagina and its entrance environment, making the insertion of the sperm injector more comfortable and smooth. When the sperm injector is inserted in place, the user does not need complex stretching and pushing operations, and only needs to control the propulsion module 3 to work by pressing the button 97 to automatically pump out semen to complete sperm injection.

[0058] Furthermore, the vibration module 2 is arranged at a position close to the head on the sperm injector, and it is also desired to be able to electrically push and pump out semen to further reduce the operation difficulty of the user. At this time, it is necessary to consider and solve the coordination and feasibility of the layout and assembly structures of the piston module 1, the vibration module 2, and the propulsion module 3. For this reason, the present invention also coordinates the layout, assembly relationship, and position relationship among the piston module 1, the vibration module 2, and the propulsion module 3, and finally meets the position requirements of the vibration module 2 and other action requirements.

[0059] The sperm injector of the present invention can improve the physiological and psychological states during sperm injection before and during the insertion, which is beneficial to the smoother and easier progress of the sperm injection process.

[0060] The second embodiment of the sperm injector See Figure 8 , different from the first embodiment, a detection module 41 and a detected part 42 are also provided in this embodiment. The detected part 42 is a magnet, and the detected part 42 is fixedly installed outside the third part 433. The detection module 41 is arranged on the first housing 493. The detection module 41 includes two detection units 411 arranged at intervals in a straight line direction. Both detection units 411 are Hall elements. When the propulsion member is at the first extreme position in the straight line direction, the detected part 42 is within the detection range of one of the detection units 411; when the propulsion member is at the second extreme position in the straight line direction, the detected part 42 is within the detection range of the other detection unit 411. In this way, when the propulsion member moves forward and backward to the corresponding extreme positions, it can be sensed, and the start and stop of the motor of the propulsion module can be controlled according to the corresponding induction signals obtained.

[0061] In addition, in this embodiment, a one-way valve 44 is sleeved outside the outlet end corresponding to the outlet hole of the piston tube. Of course, the head cover is also sleeved outside the one-way valve 44. In the natural state, the one-way valve 44 blocks the outlet hole, and after the pressure in the sperm storage space increases when the piston moves forward, the one-way valve 44 will open to connect the outlet hole.

[0062] The third embodiment of the sperm injector In the first embodiment, the semen can be automatically drawn into the liquid storage space by the backward movement of the propulsion member driving the piston backward. In contrast to the first embodiment, in this embodiment, the drawing-in operation needs to be performed manually.

[0063] Refer to Figure 9 . In this embodiment, different from the first embodiment, the first part 51 in this embodiment is not sleeved with the piston 52. Moreover, this embodiment further includes an internal part 53 that the first embodiment does not have.

[0064] Combined with Figures 10 to 12 , actually, the internal part 53 is a component for detachably connecting with the drawing rod 54. The piston 52 is sleeved outside the internal part 53, that is, the internal part 53 is located in the second cavity of the piston 52, while the first part 51 is located outside the piston 52 and abuts against the internal part 53 in a straight line direction. Among them, there is no other connection relationship between the first part 51 and the internal part 53. In this setting, when the propulsion member moves forward, the first part 51 pushes the internal part 53 forward, and the piston 52 also moves forward accordingly ( Figure 9 shown as moving in the left direction), but when the first part 51 moves backward, the internal part 53 and the piston 52 will remain in their original positions and separate from the first part 51.

[0065] Refer to Figure 11 and Figure 12 . The internal part 53 is provided with a snap hole 530. The snap hole 530 penetrates along a straight line direction, and in the projection of the straight line direction, the snap hole 530 passes through the center of the internal part 53 and is in a shape of a straight line. In addition, it can be seen that a baffle 531 and a stop block 532 are respectively arranged on the opposite sides of the straight-line-shaped snap hole 530. The stop block 532 protrudes along the straight line direction relative to the baffle 531. The two baffles 531 on both sides of the snap hole 530 are axially symmetrically arranged with the center of the internal part 53 as the center, and the two stop blocks 532 on both sides of the snap hole 530 are axially symmetrically arranged with the center of the internal part 53 as the center.

[0066] Refer to Figure 12 . This embodiment further includes an independent drawing rod 54. Of course, in other embodiments, the drawing rod may not be included, and the drawing rod needs to be equipped by the user additionally. The front end of the drawing rod 54 is a straight-line-shaped snap 541. The snap 541 passes through the center line of the drawing rod 54, and the snap 541 and the main body end face 542 of the drawing rod 54 are connected by a connecting column to form a gap 543. In the straight line direction, the size of the gap 543 is larger than the size of the baffle 531 and smaller than the size of the stop block 532.

[0067] The screwing button 541 can pass through the screwing button hole 530 which is also in a linear shape in a linear direction. Subsequently, the screwing button 541 is rotated so that the linear arm part of the screwing button 541 faces the baffle 531 in a linear direction. At this time, the baffle 531 is located in the interval 543, and at this time, the screwing button 541 and the baffle 531 restrict each other in a linear direction. In this way, through the detachable connection between the screwing button hole 530 and the screwing button 541 of the draw rod 54, the internal part 53 and the draw rod 54 are detachably connected, and after connection, the piston can be driven to retract by pulling the draw rod 54. In addition, when installing the draw rod 54, the stopper 532 can restrict the rotation of the screwing button 541 to prompt the user that the rotation is in place.

[0068] Of course, only after the piston module is disassembled can the user insert the draw rod 54 onto the internal part 53. For this reason, in this embodiment, the piston module is also set in a detachable form, that is, the piston tube, the piston 52 and the internal part 53 can be disassembled synchronously. When the piston tube is in a disassembled state, the screwing button hole 530 is exposed.

[0069] Of course, in this embodiment, although the propulsion module is not sleeved on the piston, since the propulsion module where the vibration module is located is in close contact with the internal part, the vibration of the vibration module can also be well transmitted to various parts of the piston module and the pregnancy aid head.

[0070] Finally, it should be emphasized that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
