[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figure 1-13 The present invention provides a technical solution: a food detection and extraction device, comprising a box body 1, a box door 2 is provided on the box body 1, and further comprising:

[0038] The inflatable component 3 is arranged in the box body 1. After the box door 2 is closed, the inflatable component 3 is activated by the force of the closing of the box door 2, so that the inflatable component 3 runs into the box body 1 to inflate the air, and the high-salt air in the box body 1 is squeezed out of the box body 1;

[0039] The pressure relief valve 4 is provided on the box body 1 and is used to cooperate with the inflation component 3 to make the air pressure in the box body 1 higher than the external air pressure.

[0040] The inflation component 3 includes a fixing frame 32 fixedly connected to the box body 1, a high-pressure gas tank 31 is fixedly connected to the fixing frame 32, an outlet pipe 33 is fixedly connected to the high-pressure gas tank 31, and a delay component 6 is connected to the outlet pipe 33. Using the high-pressure gas tank 31 to inflate the box body 1 is safer, does not generate heat, and can be used without external energy, saving energy.

[0041] The delay assembly 6 includes a rotating shaft 66 rotatably connected to the air outlet pipe 33, a plurality of balls 67 are fixedly connected to the rotating shaft 66, a slide groove 68 that cooperates with the plurality of balls 67 is opened in the air outlet pipe 33, a gear 61 is fixedly connected to the rotating shaft 66, and a rotating shaft 2 62 and a rotating shaft 3 64 are rotatably connected in the box body 1 respectively, two gears 2 63 are fixedly connected to the rotating shaft 2 62, and the gear 2 63 is meshed with the gear 1 61, and the rotating shaft 3 64 is fixedly connected to the gear 3 65, and the gear 3 65 is meshed with the gear 2 63, and the rotating shaft 3 64 is fixedly connected with a coil spring 69, the lower end of the rotating shaft 66 is connected to the one-way member 8, and the upper end of the rotating shaft 66 is connected to the piston 7. When the box door 2 is closed, the rack 87 drives the driving tooth 86 to rotate, and the rotation of the driving tooth 86 drives the gear 1 61 to rotate, and the rotation of the gear 1 61 drives the rotating shaft 66 to rotate. The rotation of shaft 1 66 drives shaft 2 62 and gear 2 63 to rotate. The rotation of gear 2 63 drives gear 3 65 and shaft 3 64 to rotate. The rotation of shaft 3 64 drives coil spring 69 to rotate to store force. At the same time, the rotation of shaft 1 66 causes plug 71 to move upward, thereby releasing the high-pressure gas in the high-pressure gas cylinder 31 into the box body 1. After the box door 2 is completely closed, the rack 87 stops pushing the driving tooth 86 to rotate, and the gear 1 61 loses power and the coil spring 69 begins to release, and begins to drive gear 1 61 and shaft 1 66 to rotate in the opposite direction, and drives the plug 71 to move downward, closing the high-pressure gas cylinder 31, realizing the timed closure of the high-pressure gas cylinder 31 after the box door 2 is closed, preventing the high-pressure gas cylinder 31 from releasing gas all the time, causing the staff to have to replace the high-pressure gas cylinder 31 all the time, thereby extending the service life of a single high-pressure gas cylinder 31.

[0042] The one-way member 8 includes a rotating shaft 4 82 rotatably connected to the rotating shaft 1 66, a ratchet 81 fixedly connected to the rotating shaft 4 82, a rotating shaft 5 83 rotatably connected to the gear 1 61, a torsion spring 1 84 fixedly connected to the rotating shaft 5 83, an end of the torsion spring 1 84 away from the ratchet 81 fixedly connected to the gear 1 61, a ratchet 85 fixedly connected to the rotating shaft 5 83, a driving tooth 86 fixedly connected to the rotating shaft 4 82, a rack 87 fixedly connected to the box door 2, the rack 87 and the driving tooth 86 meshing with each other, and when the box door 2 is closed, the rack 87 will mesh with the driving tooth 86. , and pushes the driving tooth 86 to rotate. The rotation of the driving tooth 86 drives the rotating shaft 4 82 to rotate. The rotation of the rotating shaft 4 82 drives the ratchet 81 to rotate. The rotation of the ratchet 81 will push the ratchet 85 to drive the gear 1 61 to rotate. After the box door 2 is closed, the rack 87 stops pushing the driving tooth 86 and the coil spring 69 begins to release to drive the gear 1 61 to rotate in the opposite direction. The ratchet 85 will not block the rotation of the ratchet 81, ensuring that when the box door 2 is opened, the rack 87 will not drive the gear 1 61 to rotate, preventing the high-pressure gas tank 31 from being opened when the box door 2 is opened.

[0043] The piston 7 includes a plug 71 threadedly connected to the rotating shaft 66, and a guide rod 72 is fixedly connected to the high-pressure gas tank 31. The guide rod 72 passes through the plug 71. When the rotating shaft 66 rotates, the plug 71 moves toward the inside of the high-pressure gas tank 31, thereby creating a gap for the high-pressure gas to be released from the high-pressure gas tank 31. The rotating shaft 66 rotates in the opposite direction to drive the plug 71 to move toward the outlet pipe 33 to close the high-pressure gas tank 31. The plug 71 is set in the high-pressure gas tank 31 to control the switch of the high-pressure gas tank 31, which can make it easier to close the high-pressure gas tank 31.

[0044] The pressure relief valve 4 includes a shell 41 fixedly connected to the box body 1, a spring 43 fixedly connected inside the shell 41, a stopper 44 fixedly connected to one end of the spring 43, and an exhaust pipe 42 fixedly connected to the shell 41. When the high-pressure gas tank 31 is inflated into the box body 1, the high-pressure gas will gradually squeeze out the air containing high salt through the exhaust pipe 42, and then the high-pressure gas tank 31 stops releasing gas. Due to the presence of the spring 43, the air pressure in the box body 1 will be higher than the external air pressure, which can effectively prevent external air from entering the box body 1.

[0045] A cooling component 5 is connected to the box body 1 for cooling the inside of the box body 1 when the temperature inside the box body 1 is too high.

[0046] The cooling component 5 includes a groove 51 provided on the box body 1, a fixing frame 52 is fixedly connected in the groove 51, a motor 53 is fixedly connected to the fixing frame 52, a fan blade 54 is fixedly connected to the output end of the motor 53, a temperature sensor 56 is fixedly connected in the box body 1, the temperature sensor 56 and the motor 53 are electrically connected, and an air guide 55 is connected to the fixing frame 52. When high temperature is generated inside the box body 1 due to the operation of the wires, the temperature sensor 56 will first detect the high temperature, and then activate the motor 53 to make the motor 53 run. The operation of the motor 53 drives the fan blade 54 to rotate, blowing air into the box body 1 for cooling and heat dissipation, thereby preventing the temperature inside the box body 1 from being too high, which will cause the wires to age faster.

[0047] The air guide part 55 includes an air collecting hood 551 fixedly connected to the box body 1, an air guide pipe 552 is fixedly connected to the air collecting hood 551, an air outlet 553 is opened on the box body 1, and the air guide pipe 552 and the air outlet 553 are connected. After the motor 53 is running, the fan blades 54 will blow the outside air into the air collecting hood 551, and then the air will be discharged from the air outlet 553 through the air guide pipe 552. When the air circulates in the air guide pipe 552, the temperature of the wall of the air guide pipe 552 will be reduced, thereby reducing the temperature of the box body 1, thereby preventing outside air from entering the box body 1 and reducing the temperature inside the box body 1.

[0048] Example 2

[0049] See also Figure 1-16 The present invention provides a technical solution: a food detection and extraction device, and Example 2 is an optimization based on Example 1.

[0050] The rack 87 is fixedly connected to a rotating shaft 6 11, one end of the rotating shaft 6 11 is fixedly connected to a fixed plate 10, and the end of the rotating shaft 6 11 away from the fixed plate 10 is fixedly connected to a fixed seat 15. A torsion spring 2 13 is fixedly connected between the rack 87, the fixed plate 10 and the fixed seat 15, and a spring 2 14 is fixedly connected in the fixed seat 15. One end of the spring 2 14 is fixedly connected to a card block 12, and the card block 12 is fixedly connected to the pull rod 9. A card slot 16 is provided on the rotating shaft 6 11. After the box door 2 is opened, the card block 12 can be disengaged from the card slot 16 by pulling the pull rod 9, and then the rack 87 is rotated upward to make the rack 87 parallel to the box door 2. After that, the pull rod 9 is released and the card block 12 will be re-engaged in the card slot 16 under the action of the spring 2 14 to fix the rack 87 in a state parallel to the box door 2, preventing the wind from blowing the box door 2 and causing the rack 87 to poke the user when the user is repairing the circuit.
