[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1-8 The embodiment of the present invention provides a technical solution: a sealed tea box with a sealing and moisture-proof function, comprising a storage box 1 and a sealed box cover 2, the sealed box cover 2 is detachably sleeved on the top opening of the storage box 1, and an annular airbag sealing ring 22 and an air cylinder assembly 3 are arranged inside the sealed box cover 2; the annular airbag sealing ring 22 has a sealing state and an assembly and disassembly state, in the sealing state, the air cylinder assembly 3 supplies air to the annular airbag sealing ring 22 to seal the gap between the sealed box cover 2 and the storage box 1, and in the assembly and disassembly state, the air cylinder assembly 3 extracts gas from the annular airbag sealing ring 22.

[0032] The sealed state refers to the sealing box cover 2 being covered on the storage box 1 to achieve sealing of the storage box 1. In the sealed state, the user manually drives the air cylinder assembly 3 to supply air to the annular airbag sealing ring 22. The annular airbag sealing ring 22 collides and deforms to fill and seal the gap after the sealing box cover 2 and the storage box 1 are covered. The assembly and disassembly state refers to the state of installing and disassembling the sealing box cover 2. During installation and disassembly, the user manually drives the air cylinder assembly 3 to exhaust the annular airbag sealing ring 22. The annular airbag sealing ring 22 shrinks and recovers, so that the annular airbag sealing ring 22 will not be damaged during installation and disassembly of the sealing box cover 2. More specifically, the present embodiment provides a sealed tea box with a sealing and moisture-proof function, which is used for storing tea. When storing tea, the tea is stored through the storage box 1 and the opening of the storage box 1 is sealed through the sealed box cover 2. An annular airbag sealing ring 22 is arranged inside the sealed box cover 2. The annular airbag sealing ring 22 is arranged on the inner circumference of the sealed box cover 2, which is a closed annular airbag structure. The circumference of the sealed box cover 2 is also provided with an air cylinder assembly 3. The air cylinder assembly 3 includes a cylindrical groove, which is integrally formed with the sealed box cover 2 or directly opened on the circumference of the sealed box cover 2. The bottom opening of the cylindrical groove is sealed, and a piston is arranged inside the cylindrical groove. One end of the cylindrical groove is connected to the inside of the annular airbag sealing ring 22 through a pipeline or a through hole opened on the sealed box cover 2. The piston arranged inside the cylindrical groove moves inside the cylindrical groove to inject air into the annular airbag sealing ring 22. The activity drive of the piston in the cylinder is manually driven, that is, the piston is connected to the annular airbag sealing ring 22 through an adjusting rod. And it extends to the outside of the cylindrical groove, and then the piston is driven to move in the cylindrical groove by manually pressing the adjusting rod. The gas inside the cylinder assembly 3 is synchronously injected into the annular airbag sealing ring 22 under the action of the piston. The annular airbag sealing ring 22 expands and deforms to seal the gap between the sealing box cover 2 and the opening on the storage box 1, thereby realizing double sealing of the top opening of the storage box 1, significantly improving the sealing effect, and preventing the tea inside the storage box 1 from getting damp and deteriorating. When opening the cover, as described above, by reversely adjusting the piston in the cylinder assembly 3, the gas in the annular airbag sealing ring 22 is extracted through the cylinder assembly 3 to shrink it, and the gas in the cylinder assembly 3 is synchronously injected into the negative pressure sealing mechanism 5, so that the annular rubber edge is separated from the annular opening on the negative pressure sealing mechanism 5, and then the sealing box cover 2 is removed. There will be no mechanical deformation or damage to the negative pressure sealing mechanism, the annular rubber edge and the annular airbag sealing ring 22, thereby preventing their deformation from affecting the sealing performance, extending the service life and further improving the sealing effect.

[0033] It also includes a negative pressure sealing mechanism 5; the negative pressure sealing mechanism 5 is arranged on the inner top of the sealing box cover 2, and the negative pressure sealing mechanism 5 is connected to the gas cylinder assembly 3; in the sealed state, the gas cylinder assembly 3 synchronously extracts the gas in the negative pressure sealing mechanism 5 to achieve double sealing of the top opening of the storage box 1. Specifically, the negative pressure sealing mechanism 5 is arranged on the inner top of the sealing box cover 2, and the negative pressure sealing mechanism 5 is a truncated cone-shaped cover body.

The other end of the cylindrical groove is connected to the top of the sealing box cover 2 through a pipeline or a through hole opened on the sealing box cover 2 and the negative pressure sealing mechanism 5 to form a closed cavity. The piston member arranged inside the cylindrical groove moves inside the cylindrical groove to inject air into the annular airbag sealing ring 22 (that is, it is in a sealed state).
