Abstract

The invention relates to a vacuum grain storage barrel capable of automatically inducing air extraction and a control method. 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 favorable for storing pet grains, and the grain storage time is prolonged. The barrel cover is tightly pressed on the barrel body through the locking device, the inside of the barrel body is ensured to be in a sealed state, and air leakage between the barrel cover and the barrel body cannot occur during subsequent vacuumizing. Because the locking device enables the barrel cover and the barrel body to be tightly pressed together all the time, air leakage is not easy to occur, the pressure maintaining time is longer, repeated vacuumizing caused by air leakage is not needed, and the power consumption is less. 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 closed at the same time, vacuumizing is started, the upper cover and an operation key do not need to be pressed in advance, and the purpose of automatic vacuumizing is achieved.

The power supply 41 supplies power to the vacuum grain storage barrel without connecting a power supply 41 line, so that the pet is prevented from being accidentally injured by household electricity; the built-in power supply 41 is also convenient to carry and use outside. The negative pressure switch 44 is preferably an electronic pressure switch, which senses pressure through a diaphragm, converts a physical signal into an electric signal through a pressure sensor, amplifies and processes the electric signal into a standard analog signal through an amplifying circuit in control, and outputs the standard analog signal or a solid-state relay. The inlet of the air suction mechanism 43 is communicated with the interior of the tub 1 to suck air in the tub 1. The negative pressure switch 44 is connected with the air suction mechanism 43, and when the negative pressure switch 44 detects that the pressure value in the barrel body 1 is reduced to the set pressure value in real time during vacuum pumping, the controller 3 controls the air suction mechanism 43 to stop working, so that a vacuum environment is formed in the barrel body 1, the vacuum environment is more favorable for storing pet food, and the food storage time is prolonged. Air inlet unit 5 includes inlet port 51 and sealing mechanism 50, and the export of inlet port 51 communicates with the inside of ladle body 1, and sealing mechanism 50 can open or close the entry of inlet port 51, when needing to open ladle lid 2, opens inlet port 51 completely through sealing mechanism 50, and the outside air gets into in ladle body 1 in the twinkling of an eye, breaks the vacuum environment in ladle body 1, alright open ladle lid 2 with quick this moment, need not to wait for the process of letting out the vacuum, reaches the effect of letting out the vacuum in the twinkling of an eye.

As shown in fig. 1 to 3, the barrel 1 and the barrel cover 2 are locked and pressed together by the locking device 6, and a closed structure is formed inside the barrel 1. The locking device 6 comprises a first lock catch 61 and a second lock catch 62 which are oppositely arranged, the first ends of the first lock catch 61 and the second lock catch 62 can be detachably connected with the barrel body 1, and the second ends of the first lock catch and the second lock catch 62 can be detachably connected with the barrel cover 2. The first and

second latches

61 and 62 are mounted at a set of opposite side walls of the tub 1, respectively. The barrel cover 2 covers the barrel body 1, the barrel cover 2 is tightly pressed on the barrel body 1 through the first lock catch 61 and the second lock catch 62, the inside of the barrel body 1 is guaranteed to be in a sealing state, and air cannot leak between the barrel cover 2 and the barrel body 1 during subsequent vacuumizing. Because the first lock catch 61 and the second lock catch 62 tightly press the barrel cover 2 and the barrel body 1 together, air leakage does not occur at ordinary times, the pressure maintaining time is longer, repeated vacuum pumping caused by air leakage is not needed, and the power consumption is less. A first trigger component and a second trigger component are arranged in the first lock catch 61 and the second lock catch 62; when ladle body 1 and bung 2 all are connected with first hasp 61 and all are connected with second hasp 62, also promptly after ladle body 1 and bung 2 carry out sealed fixed through first hasp 61 and second hasp 62, first trigger subassembly in first hasp 61 and the second hasp 62 all is close to inductive switch 42, produce electromagnetic induction between first trigger subassembly and the inductive switch 42, first trigger subassembly can trigger inductive switch 42 closed, the mechanism 43 that bleeds forms closed loop, the mechanism 43 that bleeds just this moment can start the mechanism 43 that bleeds and carry out the operation of bleeding. After the barrel body 1 and the barrel cover 2 are sealed and fixed through the first lock catch 61 and the second lock catch 62, the second trigger assembly abuts against the sealing mechanism 50, the sealing mechanism 50 is inserted into the air inlet hole 51, the inlet of the air inlet hole 51 is closed, and air leakage is avoided. After the first lock catch 61 and the second lock catch 62 are connected to the barrel body 1 and the barrel cover 2 simultaneously, the air inlet hole 51 is automatically closed, the vacuumizing is automatically started, additional operation is not needed, the operation is convenient and fast, the situation that grains in the barrel are not in a vacuum environment due to the fact that a user forgets to start the vacuumizing is avoided, and the storage time of the grains is shortened.

The Hall sensor is a magnetic field sensor manufactured according to the Hall effect, the Hall voltage changes along with the change of the magnetic field intensity, the stronger the magnetic field is, the higher the voltage is, the weaker the magnetic field is, the lower the voltage is, the Hall voltage is amplified by an amplifier in an integrated circuit, and the voltage can be amplified to be enough to output a stronger signal. If the Hall IC is used for sensing, the magnetic induction intensity needs to be changed mechanically. In the present invention, when the first magnet 631 and the second magnet 632 are respectively close to the first hall sensor 421 and the second hall sensor 422 in a one-to-one correspondence manner, the first hall sensor 421 and the second hall sensor 422 both generate hall voltages, the hall voltages are amplified and then input to corresponding modules of the controller 3 as electrical signals, and only when the first hall sensor 421 and the second hall sensor 422 generate hall voltages at the same time, the controller 3 controls the air pumping mechanism 43 to be opened to pump air in the tub. Avoid because of first hasp 61 and/or second hasp 62 not the lock and mistake pneumatic air exhaust mechanism 43, when first hasp 61 and/or second hasp 62 were the lock, bung 2 did not compress tightly on ladle body 1, had the risk of gas leakage, even start air exhaust mechanism 43 and bleed and also can't be taken out into vacuum in the bucket, under the condition that the user is unknown, can't protect the grain in the bucket effectively promptly, the electric energy of loss again.
