[0009] refer to Figures 1 to 4 The adjustable negative pressure acquisition device 1000 in this embodiment has an overall cylindrical structure, including an outer cylinder 50, a cup body 101, a soft gel 70, and a control structure 80.

[0010] like Figures 3 to 4As shown, a gap cavity 300 is formed inside the outer cylinder 50, which is used to accommodate and install the cup body 101 and the control structure 80. The outer cylinder 50 and the cup body 101 are open on one side and detachably connected to each other, and are spaced apart, thereby forming the aforementioned gap cavity 310 between the outer cylinder 50 and the cup body 101. The gap cavity 310 includes a first cavity 310a located between the bottom wall 101a of the cup body 101 and the bottom wall 50a of the outer cylinder 50, and a second cavity 310b located between the side wall 101b of the cup body 101 and the side wall 50b of the outer cylinder 50, and the two cavities 310a and 310b are interconnected. In this embodiment, the outer cylinder 50 further includes an opening 501 corresponding to the opening of the cylinder body and a bottom 502 corresponding to the bottom wall 50a. The depth of the cup body 101 is less than the depth of the outer cylinder 50, and the inner diameter gradually decreases from the opening 501 to the bottom 502, thereby forming the first cavity 310a and the second cavity 310b. It can be understood that in other embodiments, the cup body and the outer cylinder may have other structural and shaped combinations. A first vent hole 1011 and a second vent hole 1012 are provided on the bottom wall 101a of the cup body 101. The first vent hole 1011 and the second vent hole 1012 respectively penetrate the bottom wall 101a, thereby making the second cavity 310b communicate with the inner cavity 500 of the cup body 101, forming a gas channel among the first cavity 310a, the second cavity 310b, and the inner cavity 500 of the cup body 101.

[0011] The inner cavity 500 of the cup body 101 is formed as a receiving cavity for accommodating the soft gel 70. A portion of the side wall 101b of the cup body 101 has an adjustable inner diameter. The cup body 101 includes a rigid material portion and an elastically deformable body 20 exposed within the receiving cavity. The rigid material portion and the elastically deformable body 20 are sealed together to connect the elastically deformable body 20 to the outer cylinder 50. Under the action of a pressure difference, the elastically deformable body 20 can deform inward toward the interior of the cup body 101, thereby changing the inner diameter of the side wall 101b of the cup body 101. In this embodiment, the elastically deformable body 20 is an annular elastic material layer with a certain width, which can simultaneously serve as part of the side wall 101b of the cup body 101. The material thickness of the elastic material layer at the periphery of the annulus is greater than the material thickness in the middle part of the annulus, thereby forming a recessed region X in the middle part between the two peripheries. This structure is more conducive to maintaining a certain shape of the elastically deformable body and is more conducive to its fixation and shrinkage deformation. A rigid material portion is fitted onto the elastically deformable body 20 and adapted to the periphery of the elastically deformable body 20. In this embodiment, the rigid material portion includes a clamping member 40 fitted onto the middle portion of the elastically deformable body 20. The clamping member 40 includes a first clamping portion 40a and a second clamping portion 40b, which are disposed opposite to each other and fitted onto the middle portion of the elastically deformable body 20 corresponding to the recessed area X. In some embodiments, a protruding ridge is provided at the middle portion of the elastically deformable body 20, and the opposite ends of the first clamping portion 40a and the second clamping portion 40b are tightly abutted against the opposite sides of the protruding ridge.

[0012] The rigid material part also includes a cup part 10, which clamps both sides of the elastic deformable body 20 through the cup part 10 and the clamping member 40, thereby tightly connecting the rigid material part and the elastic deformable body 20.

[0013] The cup body 10 covers the end edge of the elastically deformable body 20 from one side, for example, the inner side, and the material hardness is higher than that of the elastically deformable body 20. The clamping member 40 covers the end edge of the elastically deformable body 20 from the other side, for example, the outer side, and the hardness of the clamping member 40 is also higher than that of the elastically deformable body 20. The high hardness of the cup body 10 and the clamping member 40 enables them to stably hold the elastically deformable body 20.

[0014] The upper periphery of the elastically deformable body 20 is provided with a first upper engaging portion 21, and the lower periphery is provided with a first lower engaging portion 22. On one side of the elastically deformable body 20, the first rigid material portion is provided with a cup mouth portion 110 at the upper end of the elastically deformable body 20, and a cup bottom portion 130 at the lower end of the elastically deformable body 20. The cup mouth portion 110 forms the cup mouth of the cup body 101 and covers the upper end of the elastically deformable body 20, and the cup mouth portion 110 is provided with a second upper engaging portion 111 corresponding to the first upper engaging portion 21. The cup bottom portion 30 forms the cup bottom of the cup body 101 and covers the lower end of the elastically deformable body 20, and the cup bottom portion 30 is provided with a second lower engaging portion 131 corresponding to the first lower engaging portion 22. On the other side of the elastically deformable body 20, the upper end of the second rigid material portion 40 is provided with a third upper engaging portion 41 corresponding to the first upper engaging portion 21, and the lower end is provided with a third lower engaging portion 42 corresponding to the first lower engaging portion 22. Thus, the second upper engaging part 111 and the third upper engaging part 41 clamp and engage the two sides of the first upper engaging part 21 of the elastic deformable body 20, and the second lower engaging part 131 and the third lower engaging part 42 clamp and engage the two sides of the first lower engaging part 22 of the elastic deformable body 20, which can tightly connect the rigid material part and the elastic deformable body 20. Moreover, the cup body 101 has a simple structure and is easy to install.

[0015] Here, an airbag space 200 can be formed between the side of the elastic deformable body 20 opposite to the controllable gas cavity 100 and the clamping member 40. The airbag space 200 can be in a normal pressure state, but the airbag space 200 is not limited to a normal pressure state, as long as it is higher than the controllable gas cavity 100 and sufficient to cause the elastic deformable body 20 to deform inward.

[0016] The soft gel 70 is housed within the receiving cavity of the cup body 101, and is made of soft materials such as silicone and rubber that are skin-friendly and highly flexible. The soft gel 70 has an internal receiving channel 700 that communicates with the outside, providing a passage for the insertion of sexual organs and the collection of semen. One end of the receiving channel 700 is open, forming a receiving opening 701, while the other end is closed to accommodate sexual organs. The soft gel 70, due to its material properties, can block the opening of the cup body 101, achieving an effective seal between the soft gel 70 and the cup body 101. The gas pressure between the soft gel 70 and the cup body 101 can be controlled by the control structure 80; therefore, the gas between the soft gel 70 and the cup body 101 is sometimes referred to as the controllable gas chamber 100.

[0017] At normal pressure, one side of the elastic deformable body 20 is in contact with the controllable gas chamber 100. In other words, there is a gap between the elastic deformable body 20 and the soft colloid 70, which ensures space for the elastic deformable body 20 to deform inward. The other side of the elastic deformable body 20 is isolated from the controllable gas chamber 100. When the controllable gas chamber 100 is controlled so that the gas pressure is lower than that on the other side of the elastic deformable body 20, under the pressure difference, the elastic deformable body 20 deforms inward toward the interior of the cup body 101. As the pressure difference increases, the elastic deformable body 20 gradually contacts and squeezes the receiving channel 700 of the soft colloid 70, causing it to deform.

[0018] Optionally, to further ensure the seal between the soft gel 70 and the cup body 101, a sealing ring 60 is provided between the soft gel 70 and the cup body 101.

[0019] The control structure 80 is housed within the first cavity 310a. The control structure 80 includes electronic components such as a negative pressure generating unit 81, a solenoid valve 82, a battery 83, and a control circuit 84. The negative pressure generating unit 81 is connected to the controllable gas cavity 100. Upon activation, it uses a pumping function to expel gas from the controllable gas cavity 100, gradually creating a negative pressure, i.e., a vacuum cavity. In this application, "vacuum cavity" includes both a vacuum state and a near-vacuum state. When the negative pressure generating unit 81 operates to create a vacuum in the controllable gas cavity 100, the soft gel 70 stretches within the controllable gas cavity 100 due to its material properties. The inner wall of the soft gel 70 applies a pulling force to the sexual organ towards the cup body 101, stimulating the sexual organ and thus assisting in ejaculation.

[0020] Furthermore, the solenoid valve 82 is connected to the controllable gas chamber 100. When the negative pressure generating unit 81 is working, it closes the channel to prevent gas from flowing into the controllable gas chamber 100, ensuring that the controllable gas chamber 100 can smoothly form a vacuum chamber. When the negative pressure generating unit 81 is not working, the solenoid valve 82 opens the channel, allowing gas outside the cup body 101 (such as gas in the gap chamber 300) to flow into the controllable gas chamber 100, restoring the controllable gas chamber 100 to a normal pressure state. The battery 83 provides the power required for the operation of each electronic component. The control circuit 84 controls the operation of each electronic component and may include an operating unit 841 such as control buttons and switch buttons.

[0021] The elastic deformable body 20 is annularly disposed on the side wall 101b of the cup body 101, enabling the application of compressive force to the soft gel 70 in its circumferential direction. This provides a sexual stimulation experience different from the pulling force of negative pressure directly applied to the soft gel 70, thereby assisting in ejaculation. Because the rigid material and the elastic deformable body 20 are tightly connected, the gas between the elastic deformable body 20 and the rigid material is effectively sealed. Furthermore, because the gas between the soft gel 70 and the cup body 101 is effectively sealed, the gas in the controllable gas chamber 100 is reliably controllable.

[0022] Alternatively, the cup body 101 can be a single unit, with the rigid material part being an integral structure. The rigid material part is connected to the elastically deformable body 20, and the connection is fused together, which can tightly connect the rigid material part and the elastically deformable body 20, and this method has a simpler structure.

[0023] Optionally, the elastic deformable body 20 is annularly disposed on the side wall 101b of the cup body 101. The rigid material part includes a cup mouth wall portion forming the cup mouth of the cup body and a cup bottom wall portion forming the cup bottom of the cup body. By utilizing the elasticity of the elastic deformable body 20, the elastic deformable body 20 is elastically sleeved between the cup mouth wall portion and the cup bottom wall portion, which can also tightly connect the rigid material part and the elastic deformable body 20. Moreover, this method has a simple structure and is easy to install.

[0024] Optionally, the airbag space 200 can be divided into one or more sub-divisions as needed, allowing the elastically deformable body 20 to form one or more concave structures that play an important role in subsequent use. The height, size, shape, etc., of the concavities among multiple sub-divisions can be the same or different.

[0025] Alternatively, multiple elastic deformable bodies 20 can be distributed dispersedly on the sidewall 101b of the cup body 101, for example, multiple elastic deformable bodies 20 can be distributed at intervals along a direction intersecting the radial direction, which can achieve a variety of stimulation sensations and assist in ejection.

[0026] Optionally, the outer cylinder 50 is provided with a light-transmitting viewing window 51. The overlapping portion of the viewing window 51 of the soft gel body 70 has a through-hole, ensuring that the soft gel body 70 does not obstruct the viewing window 51, allowing the patient to observe the changing state of the receiving channel 700 through the viewing window 51, particularly to determine whether semen has been collected and the amount of semen. Furthermore, when the elastic deformable body 20 is positioned facing the viewing window 51, the patient can directly observe the gradual bulging of the soft gel body 70 under the pressure of the elastic deformable body 20, providing visual assistance for ejaculation.

[0027] When using the negative pressure acquisition device 1000 of this application for treatment, such as Figure 4As shown, the operation button 841 triggers the negative pressure generating unit 81 to operate, and the solenoid valve 82 seals the controllable gas chamber 100 from the external gas. The negative pressure generating unit 81 evacuates air from the controllable gas chamber 100 inside the cup body 101. The gas discharge causes the air pressure in the controllable gas chamber 100 to gradually decrease, generating negative pressure on one side of the elastic deformable body 20. The two sides are at a higher pressure than negative pressure, such as normal pressure, thus creating a pressure difference between the two sides. This negative pressure causes the elastic deformable body 20 to elastically deform towards the receiving channel 700, and squeezes the receiving channel 700 of the soft rubber body 70, causing it to deform. As a result, the soft rubber body 70 stretches and moves towards the bottom of the cup body 101, while the inner diameter of the soft rubber body 70 narrows, providing the user with a variety of stimulation experiences, thereby assisting in ejection. In addition, because the negative pressure acquisition device 1000 of this application has a simple structure, it has good handheld operation durability.

[0028] After use, the operation button 841 triggers the negative pressure generating unit 81 to stop working, and the solenoid valve 82 connects the controllable gas chamber 100 with the external gas. Under the pressure difference, the external gas flows into the controllable gas chamber 100 until it returns to normal pressure. At this time, the soft gel 70 can be removed for easy collection of semen for testing.
