An inner side wall of the installation cavity 22 is concavely provided with a guide groove 25 extending vertically. The inner side wall of the installation cavity 22 is concavely provided with a lock groove 26 that is located beside a lower end of the guide groove 25 and that communicates the lower end of the guide groove 25. There are two guide grooves 25 provided symmetrically, and correspondingly, there are two lock grooves 25 provided radially and symmetrically. Further, the cover 20 is provided with an installation hole 27 communicating outside and the accommodating cavity 11, and the installation hole 27 is located beside the installation cavity 22.
The cover 20 is provided with a vacuumizing device 30 and a deflating component 40. The vacuumizing device 30 is an air bag vacuumizing device that compresses an air bag 31 to exhaust air in the accommodating cavity 11 to achieve a vacuum state. The deflating component 40 deflates the accommodating cavity 11. A particular description is as follows.
The vacuumizing device 30 includes the air bag 31, a lower one-way valve 32, an upper one-way valve 33, a pressing button 34 and a support spring 35. The air bag 31 is pressably provided in the installation cavity 22. The air bag 31 has a compression air cavity 301 inside. A top of the air bag 31 is provided with a second air hole 302 communicating the compression air cavity 301 and the outside. The lower one-way valve 32 is provided in the first air hole 23 to enable the accommodating cavity 11 to communicate the compression air cavity 301 in one way. The upper one-way valve 33 is provided in the second air hole 302 to enable the compression air cavity 301 to communicate the outside in one way. The pressing button 34 is provided on top of the air bag 31 and in the installation cavity 22 to enable the air bag 31 to compress downward. The support spring 35 is provided in the compression air cavity 301 to enable the air bag 31 to be restored upwards. In this embodiment, a lower opening of the air bag 31 sheathes the bump 24, and the air bag 31 is sealed and fixedly installed to the bump 24 via a first sealing ring 36. This structure is simple and is assembled easily. Further, an outer side wall of the pressing button 34 is convexly provided with a guide portion 303 moving up and down the guide groove 25. The pressing button 34 is a rotating pressing button. When the pressing button 34 is pressed down to an extreme position, the pressing button 34 rotates to lead the guide portion 303 rotating and locked into the lock groove 26, so that the pressing button 34 is fixed from springing back. Meanwhile, the pressing button 34 is not higher than a top surface of the cover 20, and thereby a size of the tank is small, facilitating transportation. Besides, there are two guide portions 303 provided radially and symmetrically. Moreover, a decorating cover plate 37 is provided in the installation cavity 22. The decorating cover plate 37 is provided with a spacing hole 304, and the pressing button 34 passes the spacing hole 304 to extend upwards. The decorating cover plate 37 is configured to limit a springing height of the pressing button 34.
The deflating component 40 includes a button member 41, a deflating spring 42 and a deflating sealing ring 43. The button member 41 is provided movable up and down in the installation hole 27. A lower end of the button member 41 extends into the accommodating cavity 11. The deflating spring 42 sheathes an upper end of the button member 41 and pushes the button member 41 to move upwards. The deflating sealing ring 43 sheathes the lower end of the button member 41 and is located in the accommodating cavity 11. The deflating sealing ring 43 seals or opens a lower opening of the installation hole 27 as the button member 41 moves up and down.
An operation principle of this embodiment is as follows.
In use, when the pressing button 34 is pressed down, the pressing button 34 squeezes the air bag 31. When the air bag 31 is compressed, the lower one-way valve 32 is automatically closed under air pressure, and the upper one-way valve 33 is automatically open to exhaust air in the compression air cavity 301. In the meantime, the support spring 35 is compressed. When the pressing button 34 is released, the support spring 35 in the air bag 31 springs back. The upper one-way valve 33 is automatically closed under air pressure. The lower one-way valve 32 is automatically open, and air in the accommodating cavity 11 of the body 10 flows into the compression air cavity 301. By repetition of the operations, the air in the accommodating cavity 11 of the body 10 may be exhausted so that the accommodating cavity 11 achieves a vacuum state.
When the cover 20 is to be opened, the button member 41 is pressed to compress the deflating spring 42. The button member 41 leads the deflating sealing ring 43 down, so that the lower opening of the installation hole 27 is open and the outer air flows into the accommodating cavity 11 of the body 10 through the installation hole 27. As a result, the vacuum state may be relieved and the cover 20 may easily be opened.
A key point of the design of the present disclosure is as follows. The vacuumizing device and the deflating component are provided. After a stuff to be stored is placed in the accommodating cavity and the cover is on, the accommodating cavity may be vacuumized through the vacuumizing device, so that the stuff to be stored may keep fresh for a long time in the vacuum state. Besides, the deflating component may be applied to relieve the vacuum state, so that it is easy to open the cover, which brings about convenience for use.
