[0025] The present invention will now be described in further detail through specific embodiments and in conjunction with the accompanying drawings.
[0026] like Figures 2 to 6 As shown, this embodiment provides a vacuum cover, including an upper cover 1, a lower cover 2, a battery 3, a vacuum pump 4, and a main control circuit board 5. The upper cover 1 covers the lower cover 2, forming a cavity between the upper cover 1 and the lower cover 2. The battery 3, the vacuum pump 4, and the main control circuit board 5 are located within the cavity. The battery 3 is electrically connected to the main control circuit board 5 for electrical input and output. The main control circuit board 5 is electrically connected to the vacuum pump 4 and controls the vacuum pump 4. The main control circuit board 5 can start and stop the vacuum pump 4 or adjust the vacuuming time. The vacuum pump 4 extends to have an inlet 41 and an outlet 42. An air intake 21 is provided at the bottom of the lower cover 2, and an exhaust 11 is provided on the upper cover 1. The air intake 41 of the vacuum pump 4 is connected to the lower cover 2. The suction port 21 is connected via an air pipe. The air outlet 42 of the vacuum pump 4 is connected to the exhaust port 11 of the upper cover 1 via an air pipe. The suction port 21 draws the gas inside the bottle into the vacuum pump 4 and then discharges it to the exhaust port 11 of the upper cover 1. A sealing ring 6 is provided at the edge of the lower cover 2. The sealing ring 6 can prevent the bottle from leaking air and achieve a vacuum effect. A vent valve 7 is provided in the cavity. A first through hole 12 is provided on the upper cover 1, and the vent valve 7 is located in the first through hole 12. A second through hole 22 is provided at the bottom of the lower cover 2, and the vent valve 7 is located on the second through hole 22. When it is necessary to open the vacuum after vacuuming, the vent valve 7 can be pressed to allow external air to enter the bottle and form a pressure balance, so that the vacuum cover can be opened easily.
[0027] Furthermore, the vent valve 7 includes a pressure member 71, a button 72, a spring 73, and a venting silicone rubber 74. The pressure member 71 is provided with a third through hole 710. The button 72 is located in the third through hole 710 and moves up and down. The venting silicone rubber 74 is located at the bottom of the pressure member 71 and is provided with a protrusion 741. The protrusion 741 is provided with a strip-shaped groove 742. The spring 73 is located between the protrusion 741 and the button 72. When the bottle is evacuated, the strip-shaped groove 742 on the protrusion 741 is tightened under pressure. When the button 72 is pressed, the protrusion 741 will deform, opening the strip-shaped groove 742, allowing external air to enter the bottle and achieving parallel air pressure. This structure is simple and convenient.
[0028] Furthermore, the bottom of the sealing ring 6 is provided with a plurality of fourth through holes 61 around the axis. The fourth through holes 61 are provided in correspondence with the second through holes 22 at the bottom of the lower cover 2. This makes it convenient to install the sealing ring 6 without having to consider alignment. It can be installed arbitrarily, making the installation quick and simple.
[0029] Furthermore, the main control circuit board 5 is provided with a start switch 51, and the upper cover 1 is provided with a fifth through hole 13. The start switch 51 is located inside the fifth through hole 13, and the start switch 51 is convenient to press on the surface of the upper cover 1.
[0030] Furthermore, the main control circuit board 5 is provided with an electrical input terminal 52, and the upper cover 1 is provided with a sixth through hole 14. The electrical input terminal 52 is located inside the sixth through hole 14, and external power is charged into the battery 3 through the electrical input terminal 52.
[0031] Furthermore, the air extraction port 21 is provided with filter cotton, which can prevent clogging and improve service life.
[0032] Furthermore, the outer periphery of the sealing ring 6 is provided with a raised edge 62, which can provide better sealing.
[0033] like Figure 1 As shown, this embodiment provides a container, a vacuum cover of the first aspect of the utility model, which also includes a container body 8, and the vacuum cover is installed on the container body 8.
[0034] By pressing the start switch 51 to start the vacuum pump 4, the air inside the bottle enters the vacuum pump 4 through the air intake 21 of the lower cover 2, and then is discharged from the air outlet 42 of the vacuum pump 4 to the exhaust port 11 of the upper cover 1. This completes the air extraction process. When the air inside the bottle is extracted, the vacuum cover needs to be opened by pressing the vent valve 7. The strip groove 742 on the protrusion 741 tightens under pressure. Pressing the button 72 on the protrusion 741 will deform the protrusion 741, opening the strip groove 742 and allowing external air to enter the bottle to form a pressure balance. The vacuum cover can then be easily opened, solving the problem of the vacuum cover being difficult to open due to the strong adhesion between it and the bottle in the existing technology.
[0035] In practical applications, coffee enthusiasts with high standards for coffee quality are a broad group. The storage environment of coffee beans directly affects the taste of the brewed coffee. High humidity accelerates coffee bean deterioration, so it is essential to keep the storage environment dry. Use airtight containers, glass jars, or vacuum containers to store coffee beans, ensuring they are well-sealed to prevent air and odors from entering. For airtight containers, the venting mode can be used during the curing period, and then switched to sealed mode after curing. This achieves both dryness and one-way venting during the curing process.
[0036] By configuring the main control circuit board 5, it can be set to stop air intake only when the air pressure reaches a set value (e.g., -35 kPa), or to periodically (e.g., at 12-hour intervals) activate the air pump motor for approximately 10 seconds to unidirectionally remove the carbon dioxide generated during the settling process. This achieves the dryness of the sealed container and the unidirectional exhaust function to isolate air from the bean growing period.
[0037] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
