As shown in fig. 16-17, each of the first unidirectional air core 302 and the second unidirectional air core 403 includes an air-through column 6, a rubber sleeve 7 and a fixing disk 8, the rubber sleeve 7 is slidably sleeved on an outer wall of one end of the air-through column 6, the fixing disk 8 is fixedly sleeved on an outer wall of the other end of the air-through column 6, and third mounting holes 801 are uniformly distributed on the fixing disk 8 along the circumferential direction;
the section of the ventilation column 6 is formed by connecting a rectangle and a trapezoid, the rectangular section part of the ventilation column 6 is concentrically provided with a circulation chamber 601 with one open end, and the open end of the circulation chamber 601 is arranged at one end close to the fixed disk 8; the vent columns 6 in the rubber sleeve 7 are symmetrically provided with air outlet holes 602, and the air outlet holes 602 are communicated with the circulation cavity 601;
the principle of the one-way gas circulation of the first one-way gas core 302 and the second one-way gas core 403 is the same, gas is blown from one end of the circulation cavity 601, the gas blown into the circulation cavity 601 is discharged from the gas outlet 602 under the action of high pressure under the action of the elastic expansion of the rubber sleeve 7, when the air pressure at the two ends of the ventilation column 6 is equal, the gas cannot flow back into the circulation cavity 601 from the gas outlet 602 under the action of the elastic expansion of the rubber sleeve 7, so that the one-way circulation of the gas is realized, and the gas is combined into the embodiment, flows into the inner box body 4 from the first one-way gas core 302 in one way, and the air in the inner box body 4 is discharged through the second one-way gas core 403 in one way.
Referring to fig. 18, when food containing water or ice is stored in the inner box 4, in order to ensure normal discharge of air in the inner box 4, an air delivery pipe 4031 is further hermetically connected to one end of the air column 6 on the second unidirectional air core 403 in a sealing manner, a floating ball 4032 is fixedly connected to the outer wall of the other end of the air delivery pipe 4031 in series, and the floating ball 4032 and the air delivery pipe 4031 are arranged in a matching manner, so that one end of the air delivery pipe 4031 can always float above water, and air can be conveniently discharged.
Referring to fig. 7 and 9-10, the inner walls of the upper ends of the four corners of the inner box 4 are fixedly connected with a fixing block 401, the center of the fixing block 401 is provided with an internal threaded hole 4011, and the internal threaded hole 4011 is used for being in threaded fit with one end of the bolt column 307;
the other end of the bolt column 307 passes through the inner box cover 3 and extends to the upper part of the inner box cover 3, and the rotating handle 304 is fixedly sleeved on one end of the bolt column 307 positioned above the inner box cover 3, so that the fixed connection between the inner box cover 3 and the inner box body 4 is convenient.
EXAMPLE III
Based on the first unidirectional gas core 302 and the second unidirectional gas core 403 described in the first embodiment and the second embodiment, in practical use, in order to play a role of corrosion prevention, the gas blown in through the gas inlet end of the first unidirectional gas core 302 is ammonia gas or inert gas.
In addition, in order to ensure that the air blown in through the first unidirectional air core 302 can push out the air in the inner box 4, the inert gas should be a gas with a relative molecular mass smaller than that of the air.
