[0017] Referring to FIGS. 1 to 6, the negative pressure airplane cup 1000 of the present disclosure has an inner diameter that can be adjusted, and has a cylindrical structure as a whole, comprising an outer cylinder 50, a cup body 101, a soft gel body 70, and a control structure 80.

[0018] The inner part of the outer cylinder 50 forms a gap cavity 300, which is used for accommodating and mounting the cup body 101 and the control structure 80.

[0019] As shown in FIGS. 3-6, the outer cylinder 50 has a gap cavity 300 formed inside for accommodating and mounting the cup body 101 and the control structure 80. The outer cylinder 50 and the cup body 101 are open at one side end edge of each other and detachably connected to each other, and the bottom of the outer cylinder 50 is spaced apart from the bottom of the cup body 101, thereby forming the gap cavity 300 between the outer cylinder 50 and the cup body 101. The gap cavity 300 includes a first cavity 300a between the bottom wall 101a of the cup body 101 and the bottom wall 50a of the outer cylinder 50, and a second cavity 300b between the side wall 101b of the cup body 101 and the side wall 50b of the outer cylinder 50, and the two cavities 300a and 300b are in communication with each other. In the present embodiment, the outer cylinder 50 further includes an opening portion 501 corresponding to the opening of the cylinder body and a bottom portion 502 corresponding to the bottom wall 50a, the cup body depth of the cup body 101 is less than the cylinder depth of the outer cylinder 50, and the inner diameter gradually decreases from the opening portion 501 to the bottom portion 502, thereby forming the first cavity 300a and the second cavity 300b. It should be understood that in other embodiments, the cup body and the outer cylinder can also be matched in other structures and shapes. The first air hole 1011 and the second air hole 1012 are formed on the bottom wall 101a of the cup body 101. The first air hole 1011 and the second air hole 1012 respectively pass through the bottom wall 101a, thereby making the second cavity 300b and the inner cavity 500 of the cup body 101 communicate with each other, and forming a gas passage among the first cavity 300a, the second cavity 300b and the inner cavity 500 of the cup body 101.

[0020] The inner cavity of the cup body 101 forms a receiving cavity 500 for receiving the soft gel 70. The gap between the cup body 101 and the soft gel 70 forms a controllable gas cavity 100. Specifically, the controllable gas cavity 100 is formed by a first wall surface 1001 as the outer surface 1001 of the soft gel 70 and a second wall surface 1002 as the inner surface 1002 of the cup body 101, and the first wall surface 1001 and the second wall surface 1002 are arranged apart by a distance. The controllable gas cavity 100 can be discharged of gas by the control structure 80 to become a state of negative pressure, so that a part of the side wall 101b of the cup body 101 has an adjustable inner diameter function. The cup body 101 includes a hard material part and an elastically deformable body 20 exposed to the receiving cavity 500 and constituting part of the side wall of the cup body 101, and the hard material part and the elastically deformable body 20 are sealingly connected to connect the elastically deformable body 20 and the outer cylinder 50 together. The elastically deformable body 20 can be deformed to recess towards the inside of the cup body 101 under the action of the pressure difference, so as to change 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 constitutes part of the side wall 101b of the cup body 101. The thickness of the elastic material layer of the outer peripheral portion (peripheral edge) of the elastically deformable body 20 is greater than the thickness of the elastic material layer of the middle portion thereof, so that the middle portion between the two peripheral edges forms a U-shaped recessed area X in cross section, which is more conducive to maintaining a certain shape of the elastically deformable body and is more conducive to its fixation and contraction deformation. The hard material part is sleeved on the elastically deformable body 20 and is adapted to the peripheral edge of the elastically deformable body 20. In this embodiment, the hard material part includes a clamping piece 40 sleeved on the middle portion of the elastically deformable body 20, and the clamping piece 40 includes a first clamping portion 40a and a second clamping portion 40b, which are oppositely arranged and sleeved on the middle portion of the elastically deformable body 20 corresponding to the recessed area X. In some embodiments, a protruding rib 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 arranged on the opposite sides of the protruding rib.

[0021] The hard material part further includes a cup body part 10, which clamps both sides of the elastically deformable body 20 through the cup body part 10 and the clamping piece 40, so as to tightly connect the hard material part and the elastically deformable body 20.

[0022] The cup body 10 covers the end edge of the elastically deformable body 20 from one side, for example, the inner side, and has a higher material hardness than the elastically deformable body 20. The holder 40 covers the end edge of the elastically deformable body 20 from the other side, for example, the outer side, and has a higher material hardness than the elastically deformable body 20. Since the cup body 100 has a higher material hardness than the elastically deformable body 20 and the holder 40 has a higher material hardness than the elastically deformable body 20, the cup body 10 and the holder 40 can stably hold the elastically deformable body 20.

[0023] The end edges of the elastically deformable body 20 are sealed by being sandwiched between the cup body 10 and the holder 40, thereby sealing the wall surface of the cup body 10. The upper end edge of the elastically deformable body 20 is provided with a first upper engaging portion 21, and the lower end edge is provided with a first lower engaging portion 22. On one side of the elastically deformable body 20, a first hard 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, a second hard material portion 40 is provided with a third upper engaging portion 41 at the upper end corresponding to the first upper engaging portion 21 and a third lower engaging portion 42 at the lower end corresponding to the first lower engaging portion 22. The second upper engaging portion 111 and the third upper engaging portion 41 sandwichingly engage the first upper engaging portion 21 of the elastically deformable body 20, and the second lower engaging portion 131 and the third lower engaging portion 42 sandwichingly engage the first lower engaging portion 22 of the elastically deformable body 20, thereby tightly connecting the hard material portion and the elastically deformable body 20, and simplifying the structure of the cup body 101 and the installation.

[0024] Here, an air bag space 200 can be formed between the other side of the elastically deformable body 20 opposite to the controllable gas cavity 100 and the holder 40. The air bag space 200 can be in an atmospheric pressure state, but the air bag space 200 can not be limited to the atmospheric pressure state, as long as it is higher than the controllable gas cavity 100 and is sufficient to cause the elastically deformable body 20 to be deformed in a concave manner.

[0025] The soft gel body 70 is housed within the receiving cavity 500 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 body 70 has an internal receiving channel 700 that communicates with the outside of the negative pressure masturbator 1000. One end of the receiving channel 700 is open, forming a receiving opening 701, and the other end is closed, for accommodating the penis (sexual organ) 1. The soft gel body 70, due to its material properties, can block the opening of the cup body 101, achieving an effective seal between the soft gel body 70 and the cup body 101. This helps to control the gas pressure in the controllable gas chamber 100 between the soft gel body 70 and the cup body 101, which is why the gas between the soft gel body 70 and the cup body 101 is sometimes referred to as the controllable gas chamber 100. In the outer cylinder 50, the accommodating channel 700 is located at the center, the controllable gas chamber 100 is arranged on the outer periphery with the accommodating channel 700 as the center, and the gap chamber 300 is arranged on the outer periphery of the controllable gas chamber 100.

[0026] In the controllable gas chamber 100, the first wall surface 1001 is closer to the receiving channel 700 than the second wall surface 1002. Under atmospheric pressure, one side of the elastic deformable body 20 is in contact with the controllable gas chamber 100, and the first wall surface 1001 and the second wall surface 1002 are separated by a gap. In other words, there is a gap between the elastic deformable body 20 and the soft gel 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 to have a lower gas pressure than the gas on the other side of the elastic deformable body 20, the controllable gas chamber 100 becomes a negative pressure. Under this negative pressure, the elastic deformable body 20 forms a concave structure that deforms inward toward the inside 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 gel 70, causing it to deform. Specifically, the recessed structure compresses the first wall surface 1001 toward the center of the receiving channel 700, forcing a portion of the receiving channel 700 to concave toward the center (i.e., narrow). On the other hand, a portion of the soft gel 70 not opposite to the recessed structure will bulge and deform under the action of negative pressure, moving away from the direction toward the receiving channel 700 and closer to the second wall surface 1002. At this time, the bottom surface 702 of the soft gel 70 may be pulled by the negative pressure and closer to the bottom wall 101a of the cup body 101. Therefore, in addition to radial deformation under negative pressure, the depth (i.e., length) of the receiving channel 700 may also become longer.

[0027] In some embodiments of this disclosure, a sealing ring 60 is provided between the soft gel 70 and the cup body 101 to further ensure the sealing between the soft gel 70 and the cup body 101.

[0028] In some embodiments of this disclosure, the inner wall of the receiving channel 700 may be designed to present a shape with folds, protrusions, etc., so as to enrich the sexual experience from a tactile perspective through contact and friction with the penis 1, and bring the user a delicate and layered stimulation.

[0029] A control structure 80 is housed within the first cavity 300a. This 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, all controlled by the control structure 80. The negative pressure generating unit 81 is connected to the controllable gas cavity 100 and is controlled by the control structure 80 to generate negative pressure. When the negative pressure generating unit 81 is activated under control, it discharges gas from the controllable gas cavity 100, gradually forming a vacuum cavity. In this disclosure, "vacuum cavity" includes both a vacuum state and a near-vacuum state. When the negative pressure generating unit 81 operates to form a vacuum cavity 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 penis 1 in the direction of the cup body 101, thus stimulating the penis 1.

[0030] In some embodiments of this disclosure, the negative pressure generating unit 81 is connected to the controllable gas chamber 100 through the first vent 1011.

[0031] When the negative pressure generating unit 81 is controlled to generate negative pressure, an exhaust channel is formed from the inside of the cup body 101 to the first vent 1011. At the same time, the solenoid valve 82 is controlled to close the second vent 1012 to prevent air from flowing into the inside of the cup body 101 from the outside. Over time, the controllable gas chamber 100 enters a negative pressure state.

[0032] When the negative pressure generating unit 81 is not controlled (i.e., closed) to generate negative pressure for exhaust, the solenoid valve 82 is controlled to establish a connection between the controllable gas chamber 100 and the gap chamber 300, opening the second vent 1012 so that air flows from the outside of the cup body 101 into the interior of the cup body 101 through the second vent 1012. Over time, the amount of gas in the controllable gas chamber 100 gradually increases, and the controllable gas chamber 100 returns to atmospheric pressure.

[0033] 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 switches.

[0034] 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, resulting in a sexual stimulation experience different from the pulling force of negative pressure directly applied to the soft gel 70. 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.

[0035] In some embodiments of this disclosure, 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.

[0036] In some embodiments of this disclosure, 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.

[0037] In some embodiments of this disclosure, the airbag space 200 can be divided into one or more regions as needed, allowing the elastically deformable body 20 to form one or more structures corresponding to each of the one or more regions of the airbag space 200, playing an important role in subsequent use. The height, size, shape, etc., of the recesses between the multiple regions can be the same or different.

[0038] In some embodiments of this disclosure, the elastic deformable body 20 includes a plurality of elastic deformable sub-body, which are disposed on the sidewall 101b of the cup body 101. For example, the plurality of elastic deformable sub-body are distributed at intervals along a direction intersecting the radial direction, which can achieve a variety of stimulation sensations and meet the needs of different users.

[0039] In some embodiments of this disclosure, a light-transmitting viewing window 51 is provided on the side wall 50b of the outer cylinder 50. An opening is formed through the overlapping portion of the viewing window 51 of the soft gel body 70, ensuring that the soft gel body 70 does not obstruct the viewing window 51, allowing the user to observe the changing state of the accommodating channel 700 through the viewing window 51. Specifically, when the elastically deformable body 20 is positioned facing the viewing window 51, the user can directly observe the gradual bulging of the soft gel body 70 under the pressure of the elastically deformable body 20 through the viewing window 51, enriching the visual experience.

[0040] When using the negative pressure masturbator 1000 disclosed herein, as shown in Figure 6, the penis 1 is inserted into the receiving channel 700 of the soft gel body 70. The operation button 841 triggers the negative pressure generating unit 81 to operate, and the solenoid valve 82 isolates the controllable gas chamber 100 from the external gas. The negative pressure generating unit 81 discharges the gas inside the cup body 101, causing the air pressure in the controllable gas chamber 100 to gradually decrease. A negative pressure is generated on one side of the elastic deformable body 20, while the other side is under a pressure environment higher than this negative pressure, i.e., at atmospheric pressure. Therefore, a pressure difference is generated on both sides of the elastic deformable body 20. This negative pressure causes the elastic deformable body 20 to elastically deform towards the receiving channel 700, and squeezes and deforms the receiving channel 700 of the soft gel body 70. As a result, the soft gel body 70 stretches and moves towards the bottom of the cup body 101, while the inner diameter of the soft gel body 70 narrows, providing the user with a variety of stimulating experiences. Furthermore, due to the simple structure of the negative pressure masturbator 1000 disclosed herein, it offers excellent durability for handheld operation.

[0041] 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 the atmospheric pressure is restored. At this time, the soft gel 70 can be removed for easy cleaning.

[0042] The disclosed negative pressure masturbator 1000 has an adjustable inner diameter, which can provide adult users with a rich variety of sexual experiences under the premise of legality, privacy and compliance with public order and good morals.

The airbag space defines one or more regions, thereby forming one or more structures corresponding to each of the one or more regions of the airbag space, the one or more structures being recessed and deformed toward the center of the cup body.

19. The negative pressure masturbator according to claim 18, characterized in that, The cup body includes: The cup mouth forms the cup body and covers the upper end of the elastically deformable body; and The bottom of the cup forms the cup body and covers the lower end of the elastically deformable body.

20. The negative pressure masturbator according to claim 12, characterized in that, The negative pressure masturbator also includes a first vent and a second vent, both of which penetrate the body of the masturbator. The negative pressure masturbator also includes a solenoid valve. When the negative pressure generating unit is controlled to generate negative pressure, an exhaust channel is formed from the inside of the cup body to the first vent, and the solenoid valve closes the second vent to prevent air from flowing into the inside of the cup body from the outside; when the negative pressure generating unit is not controlled to generate negative pressure, the solenoid valve opens the second vent so that air flows into the inside of the cup body from the outside through the second vent.
