[0028] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention more clearly understood, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the described embodiments are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0029] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0030] like Figures 1 to 5As shown, a storage barrel provided by the present invention comprises a barrel body 3, a cover body 1 and an air extraction seat 4. A storage cavity communicating with the outside is provided inside the barrel body 3. The cover body 1 and the barrel body 3 are connected to seal the storage cavity. The air extraction seat 4 and the barrel body 3 are detachably connected. A first connector is provided on the air extraction seat 4. An air extraction component is provided in the air extraction seat 4. The air extraction component comprises an air pipe and a vacuum pump 7. Both ends of the air pipe are connected to the first connector and the vacuum pump 7 respectively. A second connector is provided on the barrel body 3. The second connector is provided with a connection to the storage cavity. The first ventilation channel 301 is connected, and a valve 5 is provided at the first ventilation channel 301. When the vacuum seat 4 and the barrel body 3 are separated, the valve 5 is closed. When the vacuum seat 4 and the barrel body 3 are connected, the first connector and the second connector are connected, the valve 5 is opened, and the air pipe is connected to the first ventilation channel 301; a ring-shaped sealing groove 101 is provided on one side of the cover body 1 close to the barrel body 3, and a second sealing ring 17 is provided in the sealing groove 101. The upper end face of the barrel body 3 is inserted into the sealing groove 101 and pressed tightly against the second sealing ring 17. When the vacuum pump 7 evacuates the storage chamber, the air pressure in the storage chamber is much lower than the external air pressure, and the atmospheric pressure can press the barrel body 3 and the cover body 1 tightly, so that the upper end surface of the barrel body 3 can press the second sealing ring 17 in the sealing groove 101, thereby realizing a sealed connection between the cover body 1 and the barrel body 3; by providing a detachably connected barrel body 3 and a vacuum seat 4, the vacuum assembly is arranged in the vacuum seat 4, and when the storage barrel needs to be vacuumed, the vacuum seat 4 and the barrel body 3 can be connected. At this time, the valve 5 is opened, and the vacuum pump 7 is turned on to extract the air in the storage chamber, thereby realizing a sealed storage chamber. vacuum; after the vacuuming is completed, the vacuum seat 4 can be removed, which not only reduces the weight of the storage barrel, but also can use the vacuum seat 4 to vacuum other storage barrels, that is, one vacuum seat 4 can be suitable for multiple storage barrels, reducing the use cost of the storage barrel; when the vacuum seat 4 and the barrel body 3 are separated, the valve 5 is closed, and the outside air cannot enter the storage cavity, which can maintain the vacuum state in the storage cavity and delay the deterioration of the items stored in the storage barrel; by setting the first connector and the second connector, the connection between the barrel body 3 and the vacuum seat 4 can be facilitated, and the vacuum efficiency can be improved.

[0031] Specifically, the valve 5 includes a spring 502 and a sealing plug 503, and the spring 502 and the sealing plug 503 are both arranged in the first ventilation channel 301. One end of the spring 502 is connected to the barrel body 3, and the other end of the spring 502 is connected to the sealing plug 503. The spring 502 always has a tendency to drive the sealing plug 503 to move away from the storage cavity. The diameter of the end of the first ventilation channel 301 away from the storage cavity is smaller than the diameter of the end of the first ventilation channel 301 close to the storage cavity. When the vacuum seat 4 and the barrel body 3 are separated, the sealing plug 503 and the hole wall of the first ventilation channel 301 are pressed tightly. When the vacuum seat 4 and the barrel body 3 are connected, the vacuum seat 4 presses against the sealing plug 503, and the sealing plug 503 and the hole wall of the first ventilation channel 301 are separated. By setting the spring 502 and the sealing plug 503, when the vacuum seat 4 and the barrel body 3 are separated, under the elastic action of the spring 502, the sealing plug 503 and the hole wall of the first ventilation channel 301 are pressed tightly, so that the sealing plug 503 can block the first ventilation channel 301 and prevent external air from entering the storage cavity; when the vacuum seat 4 and the barrel body 3 are separated, the vacuum seat 4 presses against the sealing plug 503 and overcomes the elastic force of the spring 502 to make the sealing plug 503 move toward one side of the storage cavity. Since the diameter of the first ventilation channel 301 away from the storage cavity is smaller than the diameter of the first ventilation channel 301 close to the storage cavity, the position change of the sealing plug 503 makes the gap between the sealing plug 503 and the hole wall of the first ventilation channel 301 larger. At this time, the sealing plug 503 no longer blocks the first ventilation channel 301, so that the first ventilation channel 301 can be connected to the trachea, thereby realizing the vacuum extraction operation of the vacuum pump 7.

[0032] Specifically, the valve 5 includes a cap 501, a first boss 302 protruding from the wall of the storage chamber, a first vent channel 301 disposed on the first boss 302, a snap-fit ​​block 303 protruding from the periphery of the first boss 302, a snap-fit ​​groove disposed on the cap 501, into which the snap-fit ​​block 303 is inserted, and a second vent channel 504 communicating with the first vent channel 301. One end of a spring 502, distal from the sealing plug 503, is connected to the cap 501. In this embodiment, the ends of the spring 502 abut against the cap 501 and the sealing plug 503, respectively. By providing the cap 501 and the first boss 302, the valve 5 and the barrel body 3 are snap-fitted together, facilitating installation of the valve 5, reducing assembly difficulty, and thereby improving production efficiency. The snap-fit ​​block 303 and the snap-fit ​​groove have a simple structure, reducing production costs.

The second boss 401 is also provided with a sealing cover 6, which blocks the end of the third ventilation channel 402 away from the storage cavity. When the vacuum seat 4 and the barrel body 3 are connected, the unlocking block 404 presses against the sealing plug 503, and the third ventilation channel 402 is connected to the first ventilation channel 301. By setting the second boss 401, the installation of the air pipe can be facilitated, thereby facilitating the connection between the vacuum pump 7 and the first ventilation channel 301 and facilitating the vacuum operation; by setting the unlocking block 404 in the third ventilation channel 402, it can be ensured that when the unlocking block 404 is pressed against the sealing plug 503, the third ventilation channel 402 and the first ventilation channel 301 are positioned opposite each other, thereby ensuring the connection between the two.

[0034] Specifically, in this embodiment, the first connector is the third boss 403, the second connector is the connecting groove 304, the hole wall of the third ventilation channel 402 extends toward the side away from the vacuum seat 4 to form the third boss 403, and the circumference of the first ventilation channel 301 is provided with a connecting groove 304. When the vacuum seat 4 and the barrel body 3 are connected, the third boss 403 is inserted into the connecting groove 304. By providing the connecting groove 304 and the third boss 403, the vacuum seat 4 and the barrel body 3 are connected in a plug-in manner, which not only facilitates the installation and positioning between the vacuum seat 4 and the barrel body 3, but also avoids the positional offset of the vacuum seat 4 and the barrel body 3 during the vacuum operation, thereby ensuring the vacuuming effect of the storage cavity.

[0035] Specifically, a first sealing ring 16 is clamped between the third boss 403 and the wall of the connecting groove 304. The provision of the first sealing ring 16 can seal the gap between the third boss 403 and the connecting groove 304, preventing air from entering the gap between the third boss 403 and the connecting groove 304, thereby ensuring that the air extracted by the vacuum pump 7 comes from the storage chamber, thereby ensuring the vacuum extraction effect in the storage chamber.

[0036] In the present embodiment, the vacuum seat 4 is arranged at the bottom of the barrel body 3. In this case, the first ventilation channel 301 and the valve 5 are correspondingly arranged at the bottom of the barrel body 3. By arranging the vacuum seat 4 at the bottom of the barrel body 3, the gravity of the barrel body 3 itself can be used to make the unlocking block 404 press against the sealing plug 503, so that the sealing plug 503 overcomes the elastic force of the spring 502 and realizes the communication between the storage cavity and the vacuum pump 7. In other embodiments, the vacuum seat 4 can also be arranged on the side of the barrel body 3. In this case, the vacuum seat 4 and the barrel body 3 can be connected by external force or by snapping, so that the unlocking block 404 can press the sealing plug 503, so that the sealing plug 503 can overcome the elastic force of the spring 502 and move its position, thereby realizing the communication between the storage cavity and the vacuum pump 7.

[0037] Specifically, the vacuum assembly also includes a circuit board 12, an electromagnetic pressure relief valve 11, a battery 13, and a pressure sensor 18. The air pipe includes a first air pipe 8 and a second air pipe 9. The vacuum pump 7 is connected to the first ventilation channel 301 through the first air pipe 8.
