[0038] A fruit and vegetable preservation process comprises the following steps:

[0039] The heat preservation plate 7 is pushed to connect the discharge hole 9 on the heat preservation plate 7 with the refrigerated fresh-keeping chamber 2, and the fruits and vegetables are placed in the plastic bag 34 of the refrigerated fresh-keeping chamber 2, and the heat preservation plate 7 is pushed back to block the heat preservation plate 7 to seal the refrigerated fresh-keeping chamber 2, and the plastic bag 34 is heat-sealed by the heat sealing mechanism, and the refrigeration system 49 is turned on to refrigerate the refrigerated fresh-keeping chamber 2, so as to refrigerate the fruits and vegetables. The machine body 1 is moved to a suitable storage place by the front wheels 10 and the rear wheels 11. When the fruits and vegetables in the refrigerated fresh-keeping chamber 2 need to be taken out, the heat preservation plate 7 is pushed again to connect the discharge hole 9 with the refrigerated fresh-keeping chamber 2, and the plastic bag 34 is cut by the cutting mechanism, and the door body 42 is opened. The cut plastic bag 34 containing fruits and vegetables is taken out from the door body 42, and the door body 42 is closed. The fan 44 and the electric valve 45 are turned on, and the wind force of the fan 44 generates negative pressure to make the plastic bag 34 connected to the storage box 33 fit the inner wall of the refrigerated fresh-keeping chamber 2.

[0040] Implementation process:

[0041] In the initial state, the heat preservation plate 7 blocks the refrigeration and fresh-keeping chamber 2, the electric valve 45 is closed, and the first spur gear 16 is meshed with the second transmission tooth 23 on the transmission rack 20.

[0042] When the fruits and vegetables need to be refrigerated and preserved, the insulation plate 7 is pushed forward, so that the storage hole 9 on the insulation plate 7 is connected to the refrigerated and fresh-keeping chamber 2. During this process, the insulation plate 7 will drive the push piece 35 to move forward, and the push piece 35 will push the rotating piece 37, the third permanent magnet 38, the iron knife 39, and the sliding piece 50 to move forward, so that the iron knife 39 and the front wall of the refrigerated and fresh-keeping chamber 2 are against each other. Since the lowest end of the plastic bag 34 is higher than the iron piece 39 at this time, the iron knife 39 will not cut the plastic bag 34 at this time. Since the bottom wall of the second transmission chamber 4 is inclined, the rotating piece 37 will disengage from the push piece 35 after moving forward to a certain distance and against each other. At this time, the elastic telescopic part 40 is in a compressed state. The rotating piece 37, the iron knife 39, and the sliding piece 50 move backward and reset under the elastic force of the second elastic member 36. The push piece 35 continues to move forward, and the elastic telescopic part 40 can play a buffering role.

[0043] The fan 44 and the electric valve 45 are turned on, and the fan 44 draws air to the refrigerated fresh-keeping chamber 2 to generate negative pressure. Under the action of the negative pressure, the plastic bag 34 adheres to the inner wall of the refrigerated fresh-keeping chamber 2, and the fruits and vegetables are put into the refrigerated fresh-keeping chamber 2. The fruits and vegetables fall into the plastic bag 34 on the storage box 33, and the insulation board 7 is pushed back so that the insulation board 7 blocks the refrigerated fresh-keeping chamber 2. When the push piece 35 moves backward, it pushes the rotating piece 37 to rotate. When the push piece 35 is separated from the rotating piece 37, the rotating piece 37 is reset under the elastic force of the T-shaped rod 51, and the refrigeration system 49 is turned on to refrigerate. The storage and preservation cavity 2 is refrigerated to keep fruits and vegetables fresh. The body 1 is moved to a suitable storage place by the front wheel 10 and the rear wheel 11. When the rear wheel 11 rotates, one of the rear wheels 11 drives the first rotating wheel 12, the first transmission belt 13, the second transmission belt 14, the first straight gear 16, the third rotating wheel 17, and the second straight gear 18 to rotate. The first straight gear 16 drives the transmission rack 20 to move left, and the transmission rack 20 drives the first connecting piece 25, the second connecting piece 27, the second connecting piece 27, the first heat sealing strip 28, and the second heat sealing strip 18. 29 and the conductor 30, move left, the conductor 30 and the power supply 46 are electrically connected after being offset, so that the power supply 46 supplies power to the first heat sealing strip 28 and the second heat sealing strip 29. After the first heat sealing strip 28 and the second heat sealing strip 29 are started, the plastic bag 34 is pressed against the first insulation block 47 and the second insulation block 48 for heat sealing. The transmission rack 20 and the first connecting piece 25 continue to move left, compressing the first elastic member 26, so that the first heat sealing strip 28 and the second heat sealing strip 29 are heat sealed for a period of time. When the first permanent magnet 24 on the transmission rack 20 When it moves left to below the second permanent magnet 31, the second permanent magnet 31 attracts the first permanent magnet 24, causing the transmission rack 20 and the slide 19 to move up along the second track 32, the second transmission tooth 23 disengages and engages with the first spur gear 16, the first transmission tooth 22 engages with the second spur gear 18, and the second spur gear 18 rotates to drive the transmission rack 20 to reset to the right. When the transmission rack 20 moves to the right to a certain distance, the first transmission tooth 22 disengages from the second spur gear 18, and the transmission rack 20 maintains its current position and does not move.

[0044] When it is necessary to take out the fruits and vegetables in the refrigerated fresh-keeping cavity 2, the insulation plate 7 is pushed again to connect the placing hole 9 with the refrigerated fresh-keeping cavity 2. When the iron knife 39 abuts against the inner wall of the refrigerated fresh-keeping cavity 2, the plastic bag 34 is cut. After the plastic bag 34 is cut, the cut part of the plastic bag 34 is filled with fruits and vegetables and is always kept sealed. The bottom wall of the storage box 33 connected to the storage box 33 has been heat-sealed. The door body 42 is opened, and the cut plastic bag 34 containing fruits and vegetables is taken out from the door body 42. The door body 42 is closed and the fan 44 is turned on. The electric valve 45 and the wind force of the fan 44 generate a negative pressure so that the plastic bag 34 connected to the storage box 33 fits against the inner wall of the refrigerated fresh-keeping cavity 2, so that new fruits and vegetables can be put into the storage hole 9 again. The T-shaped rod 51 is pressed down, and the T-shaped rod 51 overcomes the elastic force of the third elastic member 52 and moves downward to push the transmission rack 20 downward, so that the second transmission tooth 23 and the first spur gear 16 are re-engaged, so that the transmission rack 20 can be driven to move again in the future. The T-shaped rod 51 is released, and the T-shaped rod 51 moves upward and reset under the elastic force of the third elastic member 52.

[0045] The present invention can use the refrigeration system 49 and the plastic bag 34 to keep the fruits and vegetables fresh by using cold air, and use the plastic bag 34 to isolate the fruits and vegetables from external air, thereby greatly reducing the rate at which the fruits and vegetables deteriorate, preventing the fruits and vegetables from being contaminated, and making it convenient to take out the fruits and vegetables later; the rear wheel 11 rotates to drive the first heat sealing strip 28 and the second heat sealing strip 29 to heat-seal the plastic bag 34, without the need for manual sealing, thereby improving the efficiency of the fruit and vegetable preservation process; while the insulation plate 7 is moved to put in the fruits and vegetables, the iron knife 39 can be driven to cut the plastic bag 34 to facilitate taking out the plastic bag 34 containing the fruits and vegetables; in conjunction with the fan 44, the plastic bag 34 on the storage box 33 can be conveniently laid in the refrigerated preservation cavity 2. The present invention can improve the freshness of the fruits and vegetables, and can simplify the process of the user's preservation of fruits and vegetables, thereby improving the efficiency of the preservation process.
