DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0019] See also Figure 1In this embodiment, a one-way dual-channel structure is provided, including a first shell 1, a second shell 2 and a third shell 3. The first shell 1 and the second shell 2 are connected at both ends of the third shell 3. When in use, when the medium enters the third shell 3 from the second shell 2, the first shell 1 is closed and the second shell 2 is opened; when the medium is discharged from the third shell 3 to the first shell 1, the first shell 1 is opened and the second shell 2 is closed, thereby ensuring that the medium is directional transferred and stored in the one-way dual-channel structure.

[0020] Specifically, the first shell 1 is a hollow tubular structure, and a first air duct 5 is provided at the lower end opening of the first shell 1. The first air duct 5 extends to the inner side of the first shell 1. A flange is provided at the upper end outer edge of the first shell 1. The upper end of the first shell 1 is connected to the first connecting pipe 4 through the flange. The first connecting pipe 4 is a conical tube, and a straight tube is connected to the smaller opening of the conical tube. The first connecting pipe 4 is used to connect to the third shell 3.

[0021] Specifically, the second shell 2 is a hollow tubular structure, and a flange is provided on the outer edge of the lower end of the second shell 2. The lower end of the second shell 2 is connected to the second connecting pipe 7 through the flange. The second connecting pipe 7 is a conical tube, and a straight tube is connected to the smaller opening of the conical tube. A second air duct 6 is provided at the upper end opening of the second shell 2, and the second air duct 6 is used to connect to the third shell 3.

[0022] Specifically, the third shell 3 is provided with a first interface 31, a first through hole 32, a second interface 33 and a second through hole 34. The first interface 31 is connected to the first connecting pipe 4 through a flange, and the second interface 33 is connected to the second air duct 6 through a flange. The first through hole 32 and the second through hole 34 are both located on the outer wall of the third shell 3, and the first through hole 32 is close to the first interface 31, and the second through hole 34 is close to the second interface 33.

[0023] In this embodiment, see Figure 2 As shown, a first spring 8 is arranged in a first channel formed after the first shell 1 and the first connecting pipe 4 are connected, one end of the first spring 8 is fixedly connected to the first air channel 5, and a first sphere 9 is arranged at the other end of the first spring 8, and the first sphere 9 can move axially along the first channel. When no medium enters the first shell 1, the first spring 8 abuts against the first sphere 9 and abuts against the inner wall of the first connecting pipe 4, thereby blocking the channel connecting the first interface 31 and the first connecting pipe 4, so that the first shell 1 is in a closed state; when the medium enters the first connecting pipe 4 and the first shell 1 from the first interface 31, the first sphere 9 is separated from the first connecting pipe 4, the first spring 8 is compressed, the medium is discharged from the first air channel 5, and the first shell 1 is in an open state.

[0024] In the present embodiment, a second spring 11 is arranged in a second channel formed after the second shell 2 and the second connecting tube 7 are connected. One end of the second spring 11 is fixedly connected to the second connecting tube 7. A second sphere 10 is arranged at the other end of the second spring 11. The second sphere 10 can move axially along the second channel. When no medium enters the second shell 2, the second spring 11 presses against the second sphere 10 and presses against the inner wall of the second connecting tube 7 to block the second connecting tube 7, thereby blocking the channel connecting the second air channel 6 and the second connecting tube 7, so that the second shell 2 is in a closed state; when the medium enters the second shell 2 from the second connecting tube 7, the second sphere 10 is separated from the second connecting tube 7, the second spring 11 is compressed, the medium enters the third shell 3 from the second air channel 6 and the second connecting tube 7, and the second shell 2 is in an open state.

[0025] Taking a flexible sphere as an example, the third shell 3 is fixed on the outer wall of the sphere, and the first through hole 32 and the second through hole 34 of the third shell 3 are connected to the inside of the sphere. When the medium is injected into the sphere, the medium enters the second shell 2 from the second connecting pipe 7. At this time, the second shell 2 is opened and the first shell 1 is closed. The medium enters the third shell 3 from the first through hole 32 and the second through hole 34 and enters the sphere to expand the sphere; after the pressure of the sphere increases, the medium is discharged from the third shell 3, the first shell 1 is opened, and the second shell 2 is closed, so that the medium is discharged from the first shell 1, thereby ensuring the direction transfer and storage of the medium in the unidirectional dual-channel structure, and improving the efficiency of medium transfer.

[0026] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
