In the description of the present invention, reference to the description of the terms "one embodiment," "some embodiments," "an illustrative embodiment," "an example," "a specific example," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

According to the utility model, an erection aid is disclosed, referring to fig. 1 and 2, comprising a housing 100, a piston assembly 200 and an elastic member 300, wherein the housing 100 sequentially defines an accommodating cavity 110 and a piston cavity 120 along the axial direction thereof, and a connecting hole 130 for communicating the piston cavity 120 and the accommodating cavity 110 is arranged between the accommodating cavity 110 and the piston cavity 120; the piston assembly 200 comprises a piston head 210 and a piston rod 220, the piston head 210 is slidably connected to the piston cavity 120, and the piston rod 220 is connected to the piston head 210 and used for pushing the piston head 210 to move towards the connecting hole 130; the elastic member 300 is connected between the piston rod 220 and the housing 100 for pushing the piston head 210 away from the connecting hole 130 to suck the gas of the accommodating chamber 110.

Specifically, when the erection aid is used, the user pushes the piston rod 220 along the axial direction of the housing 100, the piston rod 220 moves towards the inside of the piston cavity 120, the piston head 210 synchronously moves towards the inside of the piston cavity 120, and the elastic member 300 is compressed; thereafter, the piston rod 220 pushes the piston rod 220 and the piston head 210 to move away from the accommodating chamber 110 under the action of the elastic member 300, and the gas in the accommodating chamber 110 flows into the piston chamber 120 from the connecting hole 130 under the action of the piston head 210, so that the accommodating chamber 110 is a negative pressure chamber, and erection of the penis is facilitated. Compared with the prior art, the scheme of the application has the advantages of simple structure and convenience in operation during use.

In some embodiments, the elastic member 300 is a spring, the spring is located in the piston cavity 120, one end of the spring abuts against one end of the piston cavity 120 close to the connecting hole 130, the other end of the spring abuts against the piston head 210, and the circumference of the spring abuts against the inner wall of the piston cavity 120. Because the spring has a good elasticity, the spring has a large enough elasticity to push the piston head 210 to move away from the connecting hole 130, so as to achieve air suction of the accommodating cavity 110.

In some embodiments, referring to fig. 2 and 3, the erection aid further comprises a check valve 400, the connection hole 130 is hermetically connected with a fixing seat 410, and the check valve 400 is hermetically connected to the fixing seat 410, so that the check valve 400 is hermetically connected with the connection hole 130. Moreover, the air outlet of the check valve 400 is located in the piston cavity 120, and the air inlet of the check valve 400 is located in the accommodating cavity 110, so that air can only flow from the accommodating cavity 110 to the piston cavity 120; meanwhile, the piston head 210 comprises a connector 212 and an elastic rubber 211, the connector 212 is integrally connected to the end of the piston rod 220 or detachably connected to the end of the piston rod 220, the elastic rubber 211 is connected to the connector 212, and the peripheral surface of the elastic rubber 211 is abutted to the peripheral surface of the piston cavity 120, so that the piston head 210 is hermetically connected with the piston cavity 120.

Specifically, when the piston head 210 moves towards the inside of the piston cavity 120 during the use of the erection aid, the gas in the piston cavity 120 is compressed, and the gas outlet of the check valve 400 is located in the piston cavity 120, so that the compressed gas generates enough pressure to contract and deform the elastic rubber 211, and the gas in the piston cavity 120 is discharged from the gap between the elastic rubber 211 and the piston cavity 120 and cannot be discharged into the accommodating cavity 110. In this way, when the piston head 210 moves away from the connecting hole 130, the piston head 210 can ensure that the gas in the accommodating chamber 110 can be pumped away, thereby ensuring the vacuum degree in the accommodating chamber 110.

It should be noted that, because the stroke of the spring is short, and the stroke of the piston rod 220 is limited, the piston rod may reciprocate many times, so as to ensure that the negative pressure value of the accommodating cavity 110 meets the use value of the user. Therefore, by adopting the above scheme, it is ensured that the gas in the piston cavity 120 can be discharged from the gap between the elastic rubber 211 and the piston cavity 120, and multiple reciprocating motions of the piston rod 220 are ensured, so that the gas in the accommodating cavity 110 is sucked away.

In some embodiments, the elastic rubber 211 is made of a silicone material, so that the elastic rubber 211 has better elasticity, thereby ensuring the sealing performance between the piston head 210 and the piston cavity 120; and ensures that the elastic rubber 211 is contracted and deformed under the condition that the gas pressure is sufficiently large, so that the gas in the piston cavity 120 can be discharged.

In order to ensure that the elastic rubber 211 can be compressed and deformed under the pressure of the gas, the elastic rubber 211 is contracted and deformed. In some embodiments, the cross section of the outer peripheral surface of the elastic rubber 211 is gradually increased along the elastic direction of the elastic member 300 (the elastic direction is the sliding direction of the piston rod 220 away from the connecting hole 130), and it can be seen that the cross section of the inner end of the elastic rubber 211 is smaller, and the cross section of the outer end of the elastic rubber 211 is larger; in this way, when the elastic rubber 211 moves to the inside of the piston cavity 120, the compressed gas can gradually compress the elastic rubber 211 along the outer circumferential surface of the elastic rubber 211, so that the elastic rubber 211 deforms inwards, and the gas in the piston cavity 120 is exhausted. On the contrary, when the elastic rubber 211 moves to the outside of the piston cavity 120, the elastic rubber 211 gradually increases, thereby ensuring the sealing property between the elastic rubber 211 and the piston cavity 120.

Referring to fig. 2 and 4, to further ensure that the elastic rubber 211 can shrink and deform under the pressure of the gas, in some embodiments, the connector 212 is provided with an annular groove 2121 along its circumferential surface, and the cross section of the annular groove 2121 is circular; meanwhile, the elastic rubber 211 is provided with a circular through hole 2111 along the axial direction thereof, and the diameter of the through hole 2111 is larger than the diameter of the bottom surface of the annular groove 2121. When the elastic rubber 211 is connected to the connecting head 212, the elastic rubber 211 is connected to the outside of the connecting head 212 in a sleeved manner, one end surface of the elastic rubber 211 is connected to one annular side surface of the annular groove 2121 in an abutting manner, the other end surface of the elastic rubber 211 is connected to the other annular side surface of the annular groove 2121 in an abutting manner, and the inner wall of the through hole 2111 is separated from the bottom surface of the annular groove 2121.

By adopting the scheme, the method has the following advantages; firstly, the elastic glue 211 is convenient to mount and dismount and is more stable to connect; secondly, the sealing performance between the connector 212 and the elastic rubber 211 is better, so that air suction of the accommodating cavity 110 can be realized; thirdly, the connector 212 is rotatably connected with the elastic rubber 211, so that the piston rod 220 is prevented from driving the elastic rubber 211 to rotate when the piston rod 220 rotates, and the elastic rubber 211 is prevented from being abraded; fourthly, the inner wall of the through hole 2111 is spaced from the bottom surface of the annular groove 2121, so that the elastic rubber 211 is more easily deformed under the action of the air pressure, and the air in the piston cavity 120 is exhausted; fifthly, an inner end surface is reserved on the connecting head 212, one end of the elastic member 300 can abut against the inner end surface of the connecting head 212, the connecting head 212 has enough hardness, and the elastic member 300 can stably act on the connecting head 212.

In some embodiments, referring to fig. 2 and 5, the erection aid further comprises a locking member 500, wherein the locking member 500 is connected to the housing 100 and is located at the opening of the piston chamber 120. Meanwhile, a side wall of an end of the piston rod 220 away from the connecting head 212 is provided with a first abutting surface 2231, and the first abutting surface 2231 faces the elastic direction of the elastic member 300. When the piston rod 220 is received in the piston cavity 120, the user adjusts the locking member 500 or adjusts the piston rod 220, so that the first abutting surface 2231 abuts against the locking member 500, thereby preventing the piston rod 220 from sliding outwards, and further achieving the effect that the piston rod 220 is received in the piston cavity 120.

As mentioned above, the piston rod 220 can rotate in the piston cavity 120 (the connection head 212 is rotationally connected to the elastic rubber 211), so that the locking member 500 can be fixedly connected to the opening of the piston cavity 120, the user can disengage the first abutment surface 2231 from the locking member 500 by rotating the piston rod 220, and the piston rod 220 can normally move along the axial direction of the piston cavity 120; meanwhile, the user may rotate the piston rod 220 to rotate the first abutting surface 2231 to the inner side of the locking member 500, and then the first abutting surface 2231 abuts against the locking member 500, so that the piston rod 220 is received in the piston cavity 120.

Specifically, a strip-shaped guide groove 221 is formed in a side wall of the piston rod 220 along an axial direction thereof, one end portion of the strip-shaped guide groove 221 extends toward one end portion of the piston rod 220, a port 222 is axially formed in an end portion of the piston rod 220 close to the connector 212, and the port 222 is communicated with the end portion of the strip-shaped guide groove 221. The other end of the strip-shaped guide groove 221 extends towards the other end of the piston rod 220, a clamping groove 223 is circumferentially formed in the side wall of the end of the piston rod 220, and the clamping groove 223 is communicated with the other end of the strip-shaped guide groove 221; meanwhile, the locking member 500 is provided with a guide hole 510, a guide portion 520 protrudes radially from the inner wall of the guide hole 510, the inner end portion of the piston rod 220 is slidably disposed in the guide hole 510 and is in threaded connection with the connector 212, and the guide portion 520 slides into the bar-shaped guide groove 221 from the port 222. In this way, the locking member 500 guides the piston rod 220 when the piston rod 220 moves, so that the piston rod 220 stably moves in the axial direction of the piston chamber 120. When the piston rod 220 is received, the user rotates the piston rod 220, and the guide 520 slides circumferentially into the locking groove 223, so that the piston rod 220 is locked, and the piston rod 220 is received in the piston cavity 120.

In some embodiments, the piston head 210 has a second abutting surface 2122, and the second abutting surface 2122 can abut against the locking member 500 to prevent the piston head 210 from sliding away from the piston cavity 120. in this view, the locking member 500 has the function of preventing the piston rod 220 from sliding away from the piston cavity 120.

One end of the handle set 600 has an abutting portion 610, and the abutting portion 610 abuts and is connected between the rotary handle 700 and the piston rod 220 and is rotatably connected to the piston rod 220.

In summary, through the arrangement of the handle assembly 600, a user can conveniently hold the handle assembly 600, so as to push the piston rod 220 to move axially, and further push the piston head 210. In addition, the handle set 600 is sleeved on the outer wall of the housing 100, so as to facilitate the accommodation of the erection aid.

Further, the rotating handle 700 is connected between the handle set 600 and the piston rod 220 in an abutting manner, and thus, the handle set 600 is detached by detaching the rotating handle 700; meanwhile, the handle assembly 600 is rotatably connected with the piston rod 220 and circumferentially fixed to the housing 100, so that the handle assembly 600 is convenient to axially slide and cannot drive the rotating handle 700 to rotate, and the piston rod 220 is locked.
