Description

Built-in inflation mechanism and built-in inflation method for adult product prosthesis Technical Field

[0001] The present invention relates to an inflation mechanism for adult products, and in particular to a built-in inflation mechanism and a built-in inflation method for an adult product prosthesis. Background Art

[0002] For some silicone adult prostheses, inflation is generally used to expand or contract the prosthesis. For relevant information, please refer to the Chinese patent publication number CN107468497A, entitled "A Sex Toy with Natural Body Feeling", which states:

[0003] "A sex toy with a natural feel, comprising a column and hanging ball that simulate the male penis and testicles. When the inflatable bag is continuously squeezed, the air storage chamber is inflated and expands, effectively supporting the column, allowing it to become firm and hard, effectively simulating the erection function of the male penis. When the air valve is pressed to deflate the air storage chamber, the column returns to its soft state. During the experience, the column can be converted from soft to hard as needed. The column also features a three-layer design. The A0 hardness middle layer allows the outer layer to move or slide relative to the inner layer, simulating the properties of the male foreskin and corpus cavernosum. This makes the product of this technical solution closer to the contact effect of real sex and greatly enhances the natural feeling of sex."

[0004] The inflation mechanism in this type of product continuously squeezes the inflation bag before the adult prosthesis is used to inflate the air storage cavity. The degree of expansion of the adult prosthesis before and after use is fixed and cannot simulate the real, gradual expansion effect, so it cannot meet application requirements.

[0025] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0026] The present invention discloses a built-in inflation mechanism for an adult product prosthesis, as shown in Figures 1 to 7, which includes a fixed sleeve 2, a piston sleeve 3 and a press-and-exhaust valve 4 arranged inside the adult product prosthesis 1, the fixed sleeve 2 is close to the lower end of the adult product prosthesis 1, the piston sleeve 3 is inserted into the inner side of the upper end of the fixed sleeve 2 and the two are slidably matched, the upper end of the piston sleeve 3 is provided with an inflation hole 30 and an exhaust hole 31, the inflation hole 30 and the exhaust hole 31 are both facing the inflation chamber 10 near the upper end of the adult product prosthesis 1, the upper end of the piston sleeve 3 is provided with a first one-way valve 5 that can cover the inflation hole 30, the first one-way valve 5 is used when the air flow When the piston sleeve 3 enters the inflation chamber 10, the inflation hole 30 is opened. A lifting spring 6 and a hose 7 are provided in the fixed sleeve 2. The upper end of the lifting spring 6 abuts against the piston sleeve 3. The side of the fixed sleeve 2 is provided with an intake pipe head 20 and an exhaust pipe head 21. The upper and lower ends of the hose 7 are respectively connected to the exhaust hole 31 and the exhaust pipe head 21. The intake pipe head 20 is connected to the fixed sleeve 2. A second one-way valve 20 is provided in the intake pipe head 20. The second one-way valve 20 is used to open the intake pipe head 20 when the air flow enters the fixed sleeve 2 from the outside. The exhaust pipe head 21 is connected to the press exhaust valve 4.

[0027] In the above structure, before use, it is not necessary to fill a large amount of air into the inflation chamber 10 of the adult product prosthesis 1. It is only necessary to ensure that the adult product prosthesis 1 has an appropriate hardness. When the user repeatedly pushes and pulls the adult product prosthesis 1 during use, relative movement occurs between the fixed sleeve 2 and the piston sleeve 3. Specifically, when the piston sleeve 3 moves into the fixed sleeve 2, the air pressure in the fixed sleeve 2 drives the first one-way valve 5 to open, and the air flow enters the inflation chamber 10 from the piston sleeve 3. When the piston sleeve 3 moves out of the fixed sleeve 2, the air pressure in the fixed sleeve 2 drives the first one-way valve 5 to open. When the first one-way valve 5 is closed, the negative pressure generated in the fixed sleeve 2 drives the second one-way valve 20 to open, and the air flow enters the fixed sleeve 2 from the outside. Based on the reciprocating relative motion between the fixed sleeve 2 and the piston sleeve 3, the inflation chamber 10 is gradually inflated, the adult product prosthesis 1 gradually expands, and the hardness gradually increases, which better simulates the effect of gradual change in hardness during use. When use is completed, the inflation chamber 10 can be exhausted through the exhaust hole 31, the hose 7 and the exhaust pipe head 21 by simply pressing the press exhaust valve 4.

[0028] It should be noted that the shape of the adult product prosthesis 1 shown in FIG1 is only an application example and is not limited thereto in the actual design and manufacturing process, and may also be various other shapes. Therefore, the present invention does not limit the specific shape of the adult product prosthesis 1. That is, no matter what shape it is designed to be, what kind of usage it is used for, etc., as long as the implementation principle is the same or equivalent to the present invention, it falls within the scope of protection of the present invention.

[0029] Please refer to Figures 2 and 3. As a preferred structure, the upper end of the piston sleeve 3 is formed with an upwardly protruding ridge 32, and the inflation hole 30 and the exhaust hole 31 are both located on the inner side of the ridge 32.

[0030] To reliably control the opening and closing of the inflation hole 30, in this embodiment, the first one-way valve 5 is an umbrella-shaped one-way valve. A valve seat 33 is formed at the edge of the inflation hole 30, and the first one-way valve 5 is located within the valve seat 33. Specifically, the first one-way valve 5 is made of silicone, which is soft and self-resetting, and can reliably control the opening and closing of the inflation hole 30.

[0031] In order to ensure reliable sealing at the connection between the piston sleeve 3 and the fixed sleeve 2, in this embodiment, a piston sealing ring 34 is provided on the outer side of the piston sleeve 3, and the piston sealing ring 34 is clamped between the inner wall of the piston sleeve 3 and the fixed sleeve 2.

[0032] As shown in conjunction with Figures 3 and 6 , in this embodiment, an annular groove 35 is formed on the outer wall of the ridge 32, and an annular ridge 11 is formed on the inner wall of the adult product prosthesis 1. The annular ridge 11 is locked within the annular groove 35. Due to the engagement relationship between the annular ridge 11 and the annular groove 35, this embodiment enables the piston sleeve 3 and the adult product prosthesis 1 to move synchronously. Accordingly, a clearance groove 12 is provided on the inner wall of the adult product prosthesis 1. The clearance groove 12 should be aligned with the outer wall of the piston sleeve 3. When the adult product prosthesis 1 is pushed or pulled, the adult product prosthesis 1 at the location of the clearance groove 12 will undergo telescopic deformation due to its thinner sidewalls, thereby cooperating with the telescopic movement of the piston sleeve 3, making it easier to operate.

[0033] 4 and 5 , regarding the preferred structure of the push-to-exhaust valve 4, in this embodiment, the push-to-exhaust valve 4 includes a valve body 40, a valve core 41, a valve cap 42, a valve core spring 43 and a valve core sealing ring 44. The valve core sealing ring 44 is sleeved on the valve core 41 near the upper end, and the valve core sealing ring 44 is clamped between the end cap 410 of the valve core 41 and the top of the valve body 40. The valve cap 42 is fixed to the lower end of the valve core 41. The valve core spring 43 is sleeved on the valve core 41, and the valve core spring 43 is clamped between the valve body 40 and the valve cap 42.

[0034] In the above structure, the push-to-exhaust valve 4 is a self-locking push-to-exhaust valve. It opens when it is pressed and closes when it is pressed again. Specifically, a limit pin 400 can be provided on the inner wall of the valve body 40, and a limit groove 411 can be provided on the outer wall of the end cap 410. Each time the valve core 41 moves up and down, the limit pin 400 abuts against the two high and low positions of the limit groove 411, thereby achieving a self-locking push-to-exhaust function.

[0035] In practical applications, both the first one-way valve 5 and the second one-way valve 20 are one-way valves made of silicone material.

[0036] On this basis, the present invention also relates to a built-in inflation method for an adult product prosthesis, as shown in Figures 1 to 7, the built-in inflation method is implemented based on a built-in inflation mechanism, and the built-in inflation mechanism includes a fixed sleeve 2, a piston sleeve 3 and a press-exhaust valve 4 arranged inside the adult product prosthesis 1, the fixed sleeve 2 is close to the lower end of the adult product prosthesis 1, the piston sleeve 3 is inserted into the inner side of the upper end of the fixed sleeve 2 and the two are slidably matched, and the upper end of the piston sleeve 3 is provided with an inflation hole 30 and an exhaust hole 31, and the inflation hole 30 and the exhaust hole 31 are both facing the adult product prosthesis. 1 is located near the upper end of the inflation chamber 10. The upper end of the piston sleeve 3 is provided with a first one-way valve 5 that can cover the inflation hole 30. The fixed sleeve 2 is provided with a lifting spring 6 and a hose 7. The upper end of the lifting spring 6 abuts against the piston sleeve 3. The side of the fixed sleeve 2 is provided with an intake pipe head 20 and an exhaust pipe head 21. The upper and lower ends of the hose 7 are respectively connected to the exhaust hole 31 and the exhaust pipe head 21. The intake pipe head 20 is connected to the fixed sleeve 2. A second one-way valve 20 is provided in the intake pipe head 20. The exhaust pipe head 21 is connected to the press exhaust valve 4.

[0037] The built-in inflation method includes:

[0038] When the adult product prosthesis 1 is pushed and pulled, the fixed sleeve 2 and the piston sleeve 3 move relative to each other. When the piston sleeve 3 moves into the fixed sleeve 2, the air pressure in the fixed sleeve 2 drives the first one-way valve 5 to open, and the air flow enters the inflation chamber 10 from the piston sleeve 3. When the piston sleeve 3 moves out of the fixed sleeve 2, the first one-way valve 5 is closed, and the negative pressure generated in the fixed sleeve 2 drives the second one-way valve 20 to open, and the air flow enters the fixed sleeve 2 from the outside. Based on the reciprocating relative motion between the fixed sleeve 2 and the piston sleeve 3, the inflation chamber 10 is gradually inflated. When the press-to-exhaust valve 4 is pressed, the inflation chamber 10 is exhausted through the exhaust hole 31, the hose 7 and the exhaust pipe head 21.

[0039] Based on the aforementioned operating principle, when a user pushes or pulls the adult prosthesis 1, the fixed sleeve 2 and the piston sleeve 3 reciprocate relative to each other, gradually inflating the inflation chamber 10. During this process, the adult prosthesis 1 gradually expands and increases in hardness, effectively simulating the effect of gradual hardness change during use. When use is complete, simply press the push-to-exhaust valve 4 to exhaust the air, thereby enhancing ease of use. Furthermore, practical applications of the present invention include, but are not limited to, male anal products (prostate and anal plugs) and female massagers.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
