Example 1
Referring to fig. 1-4, a food freezing, fresh-keeping, transporting and storing device comprises a box cover 2 provided with a gas storage bin 4 and a box body 1 communicated with a nitrogen machine 14, wherein the lower surface of the box cover 2 is provided with a sealing clamping groove 3, the top end of the box body 1 is clamped with the sealing clamping groove 3, the bottom surface of the gas storage bin 4 is provided with a ventilation through hole 8, a sealing device lapped with the ventilation through hole 8 is arranged inside the gas storage bin 4, the top surface of the box cover 2 is fixedly connected with a negative pressure machine 5, the gas storage bin 4 is communicated with the negative pressure machine 5, the bottom surface of the gas storage bin 4 is fixedly connected with a one-way valve mechanism 12, when the device is used, food is stored in the box body 1, then nitrogen is flushed for fresh keeping, if a temporary cover is needed, air in the gas storage bin 4 can be pumped away and discharged by using the negative pressure machine 5, then, after nitrogen gas gets into in the gas storage storehouse 4, close sealing device, can open case lid 2, uncap temporarily, because slightly being lighter than the air of nitrogen gas, so the negative pressure in the cooperation gas storage storehouse 4, nitrogen gas just gets into in the gas storage storehouse 4 very easily, after covering case lid 2, artifical check valve mechanism 12 that uses, squeeze into box 1 again with the nitrogen gas in the gas storage storehouse 4 in, simultaneously here, thereby the air in the box 1 can be extruded and get into gas storage storehouse 4 through ventilative through-hole 8, realize gaseous exchange.
Sealing device's structure does not add the injecion, as long as satisfy can seal ventilative through-hole 8 and live, optional, in this embodiment, sealing device includes push rod 6 and sealing baffle 7, the bottom of push rod 6 and sealing baffle 7 fixed connection and sealing baffle 7's lower surface and ventilative through-hole 8 overlap joint, the top of push rod 6 run through the top surface of gas storage storehouse 4 and with bolt fixed connection, when using, mention push rod 6 and make sealing baffle 7 rise, can open ventilative through-hole 8, realize ventilative.
The temporary cover opening can retain part of the nitrogen gas, but part of the nitrogen gas is still lost, in order to replenish the lost nitrogen gas after the temporary cover opening, in the embodiment, the box body 1 is communicated with the nitrogen gas machine 14 through the gas valve 13, the gas valve 13 is electrically connected with the control device, the control device comprises the temperature measuring instrument 10 and the controller 11, the temperature measuring instrument 10 is positioned inside the box body 1, the temperature measuring instrument 10 is electrically connected with the controller 11, the controller 11 is electrically connected with the gas valve 13, when in use, after the box cover 2 is covered again, the nitrogen gas in the gas storage bin 4 is discharged, then the temperature detecting instrument 10 is opened, the temperature in the box body 1 is detected, if the temperature is higher than the previous temperature, the controller 11 is signaled, and the controller 11 controls the gas valve 13 to be opened, the nitrogen gas is added, and the temperature is.
Because nitrogen gas weight is greater than the air, so when letting in nitrogen gas, let in from the top of box 1, extrude the air downwards, extruded air can flow to division board 9 left side along the space under division board 9, continue to be extruded will get into ventilative through-hole 8, the lower surface fixedly connected with division board 9 of case lid 2 and division board 9 and the inner wall joint of box 1, leave the gap between the bottom of division board 9 and the interior diapire of box 1.
Example 2
The present embodiment explains the operation principle of the control device in embodiment 1, specifically as follows:
when in use, after the box cover 2 is covered again, the nitrogen in the gas storage bin 4 is discharged, then the temperature detector 10 is opened to detect the temperature in the box body 1, if the temperature is higher than the previous temperature, a signal is sent to the controller 11, the controller 11 controls the gas valve 13 to be opened, the nitrogen is added, and the temperature is controlled.
The utility model discloses a theory of operation is: when the box is used, food is stored in the box body 1, then nitrogen is flushed for preservation, if temporary opening is needed, air in the gas storage bin 4 can be pumped out by using the negative pressure machine 5, then the sealing device is opened to enable the nitrogen in the box body 1 to be sucked into the gas storage bin 4, after the nitrogen enters the gas storage bin 4, the sealing device is closed, the box cover 2 can be opened and temporarily opened, the nitrogen enters the gas storage bin 4 easily by matching with the negative pressure in the gas storage bin 4 due to the fact that the nitrogen is slightly lighter than the air, after the box cover 2 is covered, the one-way valve mechanism 12 is manually used to drive the nitrogen in the gas storage bin 4 into the box body 1, meanwhile, the air in the box body 1 can be extruded to enter the gas storage bin 4 through the ventilation through hole 8 to achieve gas exchange, after the box cover 2 is covered again, the nitrogen in the gas storage bin 4 is discharged, then the temperature detector 10 is opened, the temperature in the tank 1 is detected and if the temperature is higher than the previous temperature, a signal is sent to the controller 11, and the controller 11 controls the gas valve 13 to be opened, nitrogen is added and the temperature is controlled.
Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
