The invention relates to a vacuum grain storage barrel capable of automatically sensing air exhaust and a control method. The vacuum grain storage barrel comprises a barrel body, a barrel cover, a controller, a vacuumizing device, an air inlet device and a locking device. When the vacuumizing device detects that the pressure value in the barrel body is reduced to the set pressure value, the controller controls the air exhaust mechanism to stop working, a vacuum environment is formed in the barrel body, the vacuum environment is more beneficial to storage of pet food, and the food storage time is prolonged. The barrel cover is pressed on the barrel body through the locking device, it is guaranteed that the interior of the barrel body is in a sealed state, and air cannot leak between the barrel cover and the barrel body during follow-up vacuumizing. Due to the fact that the barrel cover and the barrel body are tightly pressed together all the time through the locking device, air leakage is not prone to occurring, the pressure maintaining time is longer, repeated vacuumizing caused by air leakage is not needed, and power consumption is lower. After the first lock catch and the second lock catch of the locking device are connected to the barrel body and the barrel cover at the same time, the air inlet holes are sealed at the same time, vacuumizing is started, an upper cover does not need to be pre-pressed, and an operation key does not need to be pre-pressed, so that the automatic vacuumizing purpose is achieved.
Description
technical field [0001] The invention relates to the technical field of grain storage equipment, in particular to a vacuum grain storage barrel with automatic induction pumping and a control method. Background technique [0002] Household food storage often uses vacuum storage barrels to store food for humans or animals. Existing vacuum grain storage equipment needs to be pressed by external force to make the lid and the barrel body pressed together before the air in the barrel can be successfully drawn out. The operation is cumbersome and can easily lead to failure of vacuuming. It will run all the time, and eventually the power will be exhausted, reducing the service life of the vacuum storage barrel. Secondly, the vacuum grain storage barrel of the prior art generally uses a solenoid valve to release the vacuum, which is cumbersome to operate, takes a long time to release pressure, poor user experience, and high cost; and After the battery is exhausted, it needs to be cha...
