Description

Technical Field

[0001] The invention belongs to the technical field of fresh food refrigerated transportation, in particular to a breathable and waterproof fresh food refrigerated transportation box. Background Art

[0002] With the improvement of people's living standards, people's demand for fresh products is increasing, and the types of demand are becoming more and more diverse. At present, fresh food e-commerce has become very popular, and some fresh seafood can also go to the tables in inland areas. In the process of fresh food logistics, refrigerated transportation can maximize the freshness of fresh products. In order to ensure the survival rate of fresh food, it is usually necessary to transport fresh food in water or with a fresh-keeping solution, and at the same time, good air permeability must be guaranteed. However, there is usually a big contradiction in ensuring moisture and air permeability at the same time.

[0003] During the logistics transportation process, especially when the transport box is hit or subjected to bumps and vibrations during driving, the water in the transport box will often flow out of the box, which will not only pollute the vehicle body and the ground, but also as the amount of water in the box decreases, the moisture retention of the fresh food will also decrease, affecting the survival rate of the fresh food during transportation and causing great difficulties for the fresh food logistics. Summary of the invention

[0004] In order to make up for the deficiencies of the prior art, the present invention proposes a breathable and waterproof fresh food refrigerated transport box. The present invention is mainly used to solve the problem in the prior art that fresh food products cannot be both hydrated and ventilated during refrigerated transportation.

[0005] The technical solution adopted by the present invention to solve the technical problem is as follows: the present invention provides a breathable and waterproof fresh food refrigerated transport box, comprising an inner box body, an outer box body and a breathable component;

[0006] The inner box is arranged inside the outer box; the inner box is used to place fresh products;

[0007] The space between the outer box and the inner box is used to place refrigerating substances; the outer box is made of thermal insulation material;

[0008] The air-permeable components are provided in two sets, one set is provided at the top of the inner box body, and the other set is provided at the bottom of the inner box body; the air-permeable components at the top of the inner box body are in a ventilated state, and the air-permeable components at the bottom of the inner box body are in a closed state.

[0009] By setting two sets of breathable components, specifically by setting the breathable components at the top of the inner box body in a ventilated state and the breathable components at the bottom of the inner box body in a closed state, it is possible to add water for preservation into the inner box body, thereby ensuring that the fresh products in the inner box body are placed in a ventilated and moisturizing preservation environment for transportation; at the same time, it can ensure that the water in the transport box will not spill in a bumpy carriage or during transportation, thereby ensuring that the environment during transportation will not be polluted. The refrigeration material also ensures that the inner box body maintains a low temperature, thereby ensuring the preservation effect of the fresh products in the inner box body; the refrigeration material can be ice cubes and dry ice.

[0010] Preferably, the air permeable component includes a telescopic hose, a weighted valve core and a protective cover;

[0011] One end of the telescopic hose is nested in the mounting hole on the outer box; the other end of the telescopic hose passes through the inner box, and a No. 1 vent hole is transversely arranged at the other end of the telescopic hose; a corrugated folding portion is arranged in the middle of the telescopic hose; the counterweight valve core is arranged inside the telescopic hose near one end of the inner box;

[0012] The counterweight valve core comprises a counterweight part, a connecting part and a disconnecting part; the disconnecting part is arranged at one end of the counterweight valve core; the counterweight part is arranged at the other end of the counterweight valve core; the disconnecting part and the counterweight part are connected through the connecting part; the disconnecting part is slidably connected in the telescopic hose; and a second vent hole is transversely arranged on the disconnecting part;

[0013] The protective cover is arranged inside the inner box; the protective cover is sleeved on the counterweight valve core.

[0014] When the ventilation component on the top of the inner box body is working, the counterweight part drives the on-off part to slide downward along the inner wall of the telescopic hose under the action of its own gravity, so that the No. 2 vent hole on the on-off part is aligned with the No. 1 vent hole on the telescopic hose, thereby realizing the connection between the inside of the inner box body and the outside world, thereby ensuring the air circulation in the inner box body, and thus making the fresh products placed in the inner box body have a moisturizing and breathable refrigerated environment, thereby improving the refrigeration quality of the fresh products.

[0015] When the air permeable component at the bottom of the inner box is working, the counterweight part drives the on-off part to slide downward along the inner wall of the telescopic hose under the action of its own gravity, so that the second vent hole on the on-off part and the first vent hole on the telescopic hose are staggered, thereby blocking the connection between the inside of the inner box and the outside, thereby ensuring that the water in the inner box will not flow out. By setting a protective cover, it is ensured that the fresh products in the inner box will not interfere with the action of the counterweight valve core, thereby ensuring the accuracy of the on-off of the counterweight valve core.

[0016] Preferably, the transport box further comprises a vibration component; the vibration component is arranged between the inner box body and the outer box body; the vibration component is arranged above and below the inner box body;

[0017] The vibration component includes a folding airbag, an elastic element, a sliding baffle and a slide plate; one end of the folding airbag is fixedly connected to the inner wall of the outer box body; the other end of the folding airbag is fixedly connected to the sliding baffle; the elastic element is vertically arranged inside the folding airbag; an injection hole is horizontally arranged on the folding structure of the folding airbag; an arc-shaped protrusion structure is arranged on the surface of one side of the sliding baffle close to the inner box body; the arc-shaped protrusion structure is in contact with the surface of the slide plate; and the slide plate is fixedly connected to the outer wall of the inner box body.

[0018] When the transport box is hit or the vehicle is bumped and vibrated during driving, the vibration component can absorb the impact force transmitted by the outer box, thereby ensuring that the fresh products in the inner box are not damaged by the impact force; at the same time, the vibration component can also accelerate the flow of cold air generated by the refrigeration material in the process of absorbing the impact force;

[0019] During transportation, the bumps and vibrations generated by the vehicle during driving are transmitted to the transport box, causing vertical relative movement between the inner box and the outer box, thereby squeezing the vibrating components at the bottom of the inner box, thereby compressing the air in the folded airbag, and the compressed air is ejected from the horizontally arranged jet holes on the folded airbag. The airflow generated by the ejected air drives the movement of the cold air generated by the refrigerant placed between the inner box and the outer box;

[0020] At the same time, the vibrating component on the top of the inner box will be stretched, causing the folding airbag to be elongated. The elongated folding airbag needs to have air sucked into its interior, thereby causing the cold air generated by the refrigerant placed between the inner box and the outer box to be sucked toward one side of the folding airbag, thereby realizing the movement of cold air between the inner box and the outer box, thereby achieving a more uniform refrigeration effect for the fresh products in the inner box.

[0021] Preferably, the folded airbag is a prism-shaped structure, and the larger end of the folded airbag is close to one side of the outer box body.

[0022] By setting the size of the folding airbag close to the outer box body larger than the size close to the inner box body, the refrigerant around the folding airbag cannot interfere with the folding of the folding airbag; even if the folding airbag is attached around the folding airbag, it can still be compressed inward, so that the refrigerant placed between the inner box body and the outer box body will not hinder the normal folding of the folding airbag, thereby ensuring the normal operation of the vibration component.

[0023] Preferably, the transport box further comprises a shaking component; the shaking component is arranged between the inner box body and the outer box body; the vibration component is arranged within the vertical spacing between the inner box body and the outer box body;

[0024] The shaking component includes a No. 1 annular inflatable belt and an elastic net; the No. 1 annular inflatable belt is sleeved on the outer wall of the inner box; the No. 1 annular inflatable belt and the inner wall of the outer box are connected through the elastic net.

[0025] The inner box is connected by a No. 1 ring-shaped inflatable belt and an elastic net, which not only ensures that the inner box is stably placed inside the outer box, but also allows the inner box to swing relative to the outer box, thereby achieving cushioning of the inner box. When the transport box is bumped, the impact force on the fresh products inside will not be too large, thereby achieving protection of the fresh products inside.

[0026] Preferably, the inner box body comprises an inner upper cover, an inner lower cover and an inner sealing component; the inner sealing component is arranged at the engaging position between the inner upper cover and the inner lower cover; an annular receiving groove is arranged on the engaging surface of the inner lower cover; the inner sealing component is arranged in the annular receiving groove;

[0027] The inner sealing component includes an annular sealing strip and an annular elastic member; the upper end of the annular sealing strip is fixedly connected to the snap-fit ​​surface of the inner upper cover; the lower end of the annular sealing strip is in contact with the upper end of the annular elastic member; the lower end of the annular elastic member is fixedly connected to the bottom of the annular accommodating groove.

[0028] When the inner upper cover is engaged with the inner lower cover, the annular sealing strip is inserted into the annular receiving groove, and the annular sealing strip bends after contacting the annular elastic member in the annular receiving groove. As the inner upper cover gradually presses the annular sealing strip downward, the annular sealing strip curls up in the annular receiving groove, and the annular sealing strip bends and contacts the two side walls of the annular receiving groove, thereby achieving a sealed connection between the inner upper cover and the inner lower cover, thereby ensuring that moisture in the inner box body will not penetrate from the engaging surface. By arranging an annular elastic member at the bottom of the annular receiving groove for use with the annular sealing strip, the annular sealing strip still has a good sealing effect when the pressure of the inner upper cover changes.

[0029] Preferably, the outer box body comprises an outer upper cover, an outer lower cover, an outer sealing component and a fastening component; the outer sealing component is arranged at the engaging position of the outer upper cover and the outer lower cover; an annular rectangular groove is arranged on the engaging surface of the outer upper cover and the engaging surface of the outer lower cover; the outer sealing component is arranged in the space surrounded by the annular rectangular groove on the outer upper cover and the annular rectangular groove on the outer lower cover;

[0030] The outer sealing component comprises a second annular inflatable belt; the second annular inflatable belt is filled with nitrogen;

[0031] The fastening component is arranged on the outside of the engaging surface of the outer box body; the fastening component is used to connect the outer upper cover and the outer lower cover by snapping.

[0032] When the outer upper cover and the outer lower cover are fastened together by the fastening component, the outer upper cover squeezes the No. 2 annular inflatable belt in the annular rectangular groove, and the squeezed and deformed No. 2 annular inflatable belt blocks the seam of the clamping surface of the outer upper cover and the outer lower cover, thereby realizing the sealed connection between the outer upper cover and the outer lower cover through the No. 2 annular inflatable belt, thereby preventing the cold air generated by the refrigeration material in the outer box from leaking from the clamping surface of the outer upper cover and the outer lower cover. Nitrogen is filled in the No. 2 annular inflatable belt, so that the squeezing force of the No. 2 annular inflatable belt on the clamping surface seam will not be affected by the external temperature, thereby ensuring the stability of the sealing effect, thereby increasing the refrigeration time of the transport box for fresh products.

[0033] Preferably, the transport box also includes a shock-absorbing component and a supporting component; the shock-absorbing component is arranged at the bottom of the outer box body; the shock-absorbing component is used to reduce the vibration generated by the transport vehicle; the supporting component is arranged at the top of the outer box body; the supporting component is used to block the items above the transport box and close the ventilation holes on the top of the transport box.

[0034] The beneficial effects of the present invention are as follows:

[0035] 1. In the present invention, two sets of air-permeable components are provided, specifically, the air-permeable components at the top of the inner box body are provided in a ventilated state, while the air-permeable components at the bottom of the inner box body are provided in a closed state, so that water for preservation can be added into the inner box body, thereby ensuring that the fresh products in the inner box body are placed in a ventilated and moisturizing preservation environment for transportation; at the same time, it can ensure that the water in the transport box will not spill in a bumpy carriage or during transportation, thereby ensuring that the environment will not be polluted during transportation.

[0036] 2. When the ventilation component on the top of the inner box body of the present invention is working, the counterweight part drives the on-off part to slide downward along the inner wall of the telescopic hose under the action of its own gravity, so that the No. 2 vent hole on the on-off part is aligned with the No. 1 vent hole on the telescopic hose, thereby realizing the connection between the inside of the inner box body and the outside, thereby ensuring the air circulation in the inner box body, and thus making the fresh products placed in the inner box body have a moisturizing and breathable refrigerated environment, thereby improving the refrigeration quality of the fresh products.

[0037] 3. In the present invention, when the transport box is hit or subjected to bumps and vibrations during driving of the vehicle, the vibration component can absorb the impact force transmitted by the outer box body, thereby ensuring that the fresh products in the inner box body are not damaged by the impact force; at the same time, the vibration component can also accelerate the flow of cold air generated by the refrigerant in the process of absorbing the impact force, thereby achieving a more uniform refrigeration effect for the fresh products in the inner box body.

[0038] 4. In the present invention, the inner box is connected by a No. 1 ring-shaped inflatable belt and an elastic net, which not only ensures that the inner box is stably placed inside the outer box, but also enables the inner box to shake relative to the outer box, thereby achieving buffering of the inner box, and further ensuring that the impact force on the fresh products inside the transport box will not be too large when it is bumped, thereby achieving protection of the fresh products inside.

[0039] 5. In the present invention, the annular sealing strip is curled up in the annular containing groove, and after being bent, the annular sealing strip contacts the two side walls of the annular containing groove, thereby realizing a sealed connection between the inner upper cover and the inner lower cover, thereby ensuring that the moisture in the inner box body will not penetrate out from the engaging surface; by arranging an annular elastic member at the bottom of the annular containing groove for use with the annular sealing strip, the annular sealing strip still has a good sealing effect when the pressure of the inner upper cover changes.

DETAILED DESCRIPTION

[0048] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0049] like Figure 1 As shown, a breathable and waterproof fresh food refrigerated transport box comprises an inner box body 1, an outer box body 2 and a breathable component 3;

[0050] The inner box body 1 is arranged inside the outer box body 2; the inner box body 1 is used to place fresh products;

[0051] The outer box 2 and the inner box 1 are used to place refrigerating substances; the outer box 2 is made of thermal insulation material;

[0052] The air-permeable component 3 is provided in two sets, one set is provided at the top of the inner box body 1, and the other set is provided at the bottom of the inner box body 1; the air-permeable component 3 at the top of the inner box body 1 is in a ventilated state, and the air-permeable component 3 at the bottom of the inner box body 1 is in a closed state.

[0053] By setting two sets of air-permeable components 3, specifically by setting the air-permeable components 3 at the top of the inner box 1 in a ventilated state, and the air-permeable components 3 at the bottom of the inner box 1 in a closed state, it is possible to add water for preservation into the inner box 1, thereby ensuring that the fresh products in the inner box 1 are placed in a ventilated and moisturizing preservation environment for transportation; at the same time, it can ensure that the water in the inner box 1 will not spill in a bumpy carriage or during transportation, thereby ensuring that the environment during transportation will not be polluted. The refrigeration material also ensures that the inner box 1 maintains a low temperature, thereby ensuring the preservation effect of the fresh products in the inner box 1; the refrigeration material can be ice cubes and dry ice.

[0054] like Figures 1 to 3As shown, the air permeable component 3 includes a telescopic hose 31, a weighted valve core 32 and a protective cover 33;

[0055] One end of the telescopic hose 31 is embedded in the mounting hole on the outer box 2; the other end of the telescopic hose 31 passes through the inner box 1, and a first vent hole 311 is transversely arranged at the other end of the telescopic hose 31; a corrugated folding portion 312 is arranged in the middle of the telescopic hose 31; the counterweight valve core 32 is arranged inside the telescopic hose 31 near one end of the inner box 1;

[0056] The counterweight valve core 32 includes a counterweight portion 321, a connecting portion 322 and a disconnecting portion 323; the disconnecting portion 323 is provided at one end of the counterweight valve core 32; the counterweight portion 321 is provided at the other end of the counterweight valve core 32; the disconnecting portion 323 is connected to the counterweight portion 321 through the connecting portion 322; the disconnecting portion 323 is slidably connected in the telescopic hose 31; a second vent hole 324 is transversely provided on the disconnecting portion 323;

[0057] The protective cover 33 is disposed inside the inner box 1 ; the protective cover 33 is sleeved on the counterweight valve core 32 .

[0058] When the ventilation component 3 on the top of the inner box body 1 is working, the counterweight part 321 drives the on-off part 323 to slide downward along the inner wall of the telescopic hose 31 under the action of its own gravity, so that the second air hole 324 on the on-off part 323 is aligned with the first air hole 311 on the telescopic hose 31, thereby realizing the connection between the inside of the inner box body 1 and the outside, thereby ensuring the air circulation in the inner box body 1, and thus making the fresh products placed in the inner box body 1 have a moisturizing and breathable refrigerated environment, thereby improving the refrigeration quality of the fresh products.

[0059] When the air permeable component 3 at the bottom of the inner box 1 is working, the counterweight 321 drives the on-off part 323 to slide downward along the inner wall of the telescopic hose 31 under the action of its own gravity, so that the second vent hole 324 on the on-off part 323 is staggered with the first vent hole 311 on the telescopic hose 31, thereby blocking the connection between the inside of the inner box 1 and the outside, thereby ensuring that the water in the inner box 1 does not flow out. By setting the protective cover 33, it is ensured that the fresh products in the inner box 1 will not interfere with the action of the counterweight valve core 32, thereby ensuring the accuracy of the on-off of the counterweight valve core 32.

[0060] like Figure 1 and Figure 4 As shown, the transport box further includes a vibration component 4; the vibration component 4 is arranged between the inner box body 1 and the outer box body 2; the vibration component 4 is arranged above and below the inner box body 1;

[0061] The vibration component 4 includes a folding airbag 41, an elastic element 42, a sliding baffle 43 and a slide plate 44; one end of the folding airbag 41 is fixedly connected to the inner wall of the outer box body 2; the other end of the folding airbag 41 is fixedly connected to the sliding baffle 43; the elastic element 42 is vertically arranged inside the folding airbag 41; the injection hole 411 is horizontally arranged on the folding structure of the folding airbag 41; the surface of the sliding baffle 43 on one side close to the inner box body 1 is provided with an arc-shaped protrusion structure 431; the arc-shaped protrusion structure 431 is in contact with the surface of the slide plate 44; the slide plate 44 is fixedly connected to the outer wall of the inner box body 1.

[0062] When the transport box is hit or the vehicle is bumped and vibrated during driving, the vibration component 4 can absorb the impact force transmitted by the outer box body 2, thereby ensuring that the fresh products in the inner box body 1 are not damaged by the impact force; at the same time, the vibration component 4 can also accelerate the flow of cold air generated by the refrigeration material in the process of absorbing the impact force;

[0063] During transportation, the bumpy vibration generated by the vehicle during driving is transmitted to the transport box, causing vertical relative movement between the inner box 1 and the outer box 2, thereby squeezing the vibrating component 4 at the bottom of the inner box 1, thereby compressing the air in the folded airbag 41, and the compressed air is ejected from the jet holes 411 horizontally arranged on the folded airbag 41. The airflow generated by the ejected air promotes the movement of the cold air generated by the refrigerant placed between the inner box 1 and the outer box 2;

[0064] At the same time, the vibrating component 4 on the top of the inner box body 1 will be stretched, thereby causing the folded airbag 41 to be elongated. The elongated folded airbag 41 needs to suck air into its interior, thereby achieving the goal of sucking the cold air generated by the refrigerant placed between the inner box body 1 and the outer box body 2 toward one side of the folded airbag 41, thereby achieving the movement of cold air between the inner box body 1 and the outer box body 2, thereby achieving a more uniform refrigeration effect for the fresh products in the inner box body 1.

[0065] like Figure 4 As shown, the folded airbag 41 is a prism-shaped structure, and the larger end of the folded airbag 41 is close to one side of the outer box body 2.

[0066] By setting the size of the folding airbag 41 close to the outer box body 2 to be larger than the size close to the inner box body 1, the refrigerant around the folding airbag 41 cannot interfere with the folding of the folding airbag 41; even if the folding airbag 41 is attached around the folding airbag 41, it can still be compressed inward, so that the refrigerant placed between the inner box body 1 and the outer box body 2 will not hinder the normal folding of the folding airbag 41, thereby ensuring the normal operation of the vibration component 4.

[0067] like Figure 1 and Figure 5 As shown, the transport box further includes a shaking component 5; the shaking component 5 is arranged between the inner box body 1 and the outer box body 2; the vibration component 4 is arranged in the vertical spacing between the inner box body 1 and the outer box body 2;

[0068] The shaking component 5 includes a number one annular inflatable belt 51 and an elastic net 52 ; the number one annular inflatable belt 51 is sleeved on the outer wall of the inner box body 1 ; the number one annular inflatable belt 51 and the inner wall of the outer box body 2 are connected via the elastic net 52 .

[0069] The inner box body 1 is connected by a No. 1 annular inflatable belt 51 and an elastic net 52, which not only ensures that the inner box body 1 is stably placed inside the outer box body 2, but also allows the inner box body 1 to swing relative to the outer box body 2, thereby achieving buffering of the inner box body 1, and further, when the transport box is bumped, the impact force on the fresh products inside will not be too large, thereby achieving protection of the fresh products inside.

[0070] like Figure 1 and Figure 5 As shown, the inner box body 1 includes an inner upper cover 11, an inner lower cover 12 and an inner sealing component 13; the inner sealing component 13 is provided at the engaging position of the inner upper cover 11 and the inner lower cover 12; an annular receiving groove 121 is provided on the engaging surface of the inner lower cover 12; the inner sealing component 13 is arranged in the annular receiving groove 121;

[0071] The inner sealing component 13 includes an annular sealing strip 131 and an annular elastic member 132; the upper end of the annular sealing strip 131 is fixedly connected to the engaging surface of the inner upper cover 11; the lower end of the annular sealing strip 131 is in contact with the upper end of the annular elastic member 132; the lower end of the annular elastic member 132 is fixedly connected to the bottom of the annular accommodating groove 121.

[0072] When the inner upper cover 11 and the inner lower cover 12 are engaged, the annular sealing strip 131 is inserted into the annular receiving groove 121, and the annular sealing strip 131 bends after contacting the annular elastic member 132 in the annular receiving groove 121. As the inner upper cover 11 gradually increases the degree of pressing the annular sealing strip 131 downward, the annular sealing strip 131 curls up in the annular receiving groove 121, and the annular sealing strip 131 bends and contacts the two side walls of the annular receiving groove 121, thereby achieving a sealed connection between the inner upper cover 11 and the inner lower cover 12, thereby ensuring that the moisture in the inner box body 1 will not penetrate from the engaging surface. By arranging the annular elastic member 132 at the bottom of the annular receiving groove 121 for use with the annular sealing strip 131, the annular sealing strip 131 still has a good sealing effect when the pressure of the inner upper cover 11 changes.

[0073] like Figure 1 and Figure 6 As shown, the outer box body 2 includes an outer upper cover 21, an outer lower cover 22, an outer sealing component 23 and a fastening component 24; the outer sealing component 23 is arranged at the engaging position of the outer upper cover 21 and the outer lower cover 22; an annular rectangular groove 211 is arranged on the engaging surface of the outer upper cover 21 and the engaging surface of the outer lower cover 22; the outer sealing component 23 is arranged in the space surrounded by the annular rectangular groove 211 on the outer upper cover 21 and the annular rectangular groove 211 on the outer lower cover 22;

[0074] The outer sealing component 23 includes a second annular inflatable belt 231; the second annular inflatable belt 231 is filled with nitrogen;

[0075] The fastening component 24 is disposed outside the engaging surface of the outer box body 2 ; the fastening component 24 is used to connect the outer upper cover 21 and the outer lower cover 22 by snapping.

[0076] When the outer upper cover 21 and the outer lower cover 22 are fastened together by the fastening component 24, the outer upper cover 21 squeezes the second annular inflatable belt 231 in the annular rectangular groove 211, and the second annular inflatable belt 231 after being squeezed and deformed blocks the seam of the engaging surface of the outer upper cover 21 and the outer lower cover 22, thereby realizing the sealed connection between the outer upper cover 21 and the outer lower cover 22 through the second annular inflatable belt 231, thereby preventing the cold air generated by the refrigerant in the outer box body 2 from leaking from the engaging surface of the outer upper cover 21 and the outer lower cover 22. Nitrogen is filled in the second annular inflatable belt 231, so that the squeezing force of the second annular inflatable belt 231 on the engaging surface seam will not be affected by the external temperature, thereby ensuring the stability of the sealing effect, thereby increasing the refrigeration time of the transport box for fresh products.

[0077] like Figure 1 and Figure 4 As shown, the transport box also includes a shock-absorbing component 6 and a supporting component 7; the shock-absorbing component 6 is arranged at the bottom of the outer box body 2; the shock-absorbing component 6 is used to reduce the vibration generated by the transport vehicle; the supporting component 7 is arranged at the top of the outer box body 2; the supporting component 7 is used to block the objects above the transport box and close the ventilation holes on the top of the transport box.

[0078] The vent hole 324 on the on-off part 323 is aligned with the vent hole 311 on the telescopic hose 31, thereby realizing the connection between the interior of the inner box body 1 and the outside, thereby ensuring the air circulation in the inner box body 1, thereby providing the fresh food placed in the inner box body 1 with a moisturizing and breathable refrigerated environment, thereby improving the refrigeration quality of the fresh food; when the vent hole 324 on the bottom of the inner box body 1 is working, the vent hole 324 on the on-off part 323 is aligned with the vent hole 311 on the telescopic hose 31, thereby blocking the connection between the interior of the inner box body 1 and the outside, thereby ensuring that water in the inner box body 1 does not flow out; During transportation, the bumpy vibration generated by the vehicle during driving is transmitted to the transport box, causing vertical relative movement between the inner box body 1 and the outer box body 2, thereby squeezing the vibrating component 4 at the bottom of the inner box body 1, thereby compressing the air in the folding airbag 41, and the compressed air is ejected from the jet holes 411 horizontally arranged on the folding airbag 41. The airflow generated by the ejected air promotes the movement of cold air generated by the refrigerant placed between the inner box body 1 and the outer box body 2; at the same time, the vibrating component 4 at the top of the inner box body 1 will be stretched, thereby causing the folded airbag 41 to be elongated. The elongated folding airbag 41 needs to draw air into it, thereby realizing the suction of the cold air generated by the refrigerant placed between the inner box body 1 and the outer box body 2 to the side of the folding airbag 41, thereby realizing the movement of cold air between the inner box body 1 and the outer box body 2, thereby achieving a more uniform refrigeration effect for the fresh products in the inner box body 1.
