Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cold chain transportation equipment, and in particular to a cold chain turnover box with temperature regulation function. BACKGROUND

[0002] The cold chain turnover box, also known as a logistics box, is a heat preservation box specially used for storing and transporting cold chain products, and can maintain the temperature of the products stable during storage and transportation, protecting the quality and safety of the products.

[0003] The traditional cold chain turnover box usually has multiple condensing plates installed inside, and the items to be stored at low temperature are stored in the space enclosed by the multiple condensing plates. The condensing plates can continuously cool the space inside the cold chain turnover box through the circulation of the refrigerant inside, so as to keep the space inside the cold chain turnover box at a low temperature, facilitating the low-temperature storage of the items.

[0004] However, when using the traditional cold chain turnover box, it is difficult to control the cooling effect of the condensing plates, so the cooling effect of the condensing plates remains relatively stable during the cooling process. When the low-temperature environment required by the stored items is higher than the temperature maintained by the condensing plates in the space inside the cold chain turnover box, the quality of the items is easily affected by the excessive low temperature.

[0005] Therefore, there is an urgent need for a cold chain turnover box with temperature regulation function. SUMMARY

[0006] The present application provides a cold chain turnover box with temperature regulation function, which can adjust the cooling effect on the stored items inside the cold chain turnover box according to the temperature change inside the cold chain turnover box, to ensure the quality of the items.

[0007] The present application provides a cold chain turnover box with temperature regulation function, which adopts the following technical solution:

[0008] A cold chain turnover box with temperature regulation function, comprising an outer box structure, an inner box structure and a plurality of temperature regulating devices;

[0009] The outer box structure comprises an outer box body and an outer box cover; the inner part of the outer box body has a mounting space adapted to the inner box structure, and the mounting space forms a mounting port on one side of the outer box body; the outer box cover is movably connected with the outer box body, and the outer box cover can control the opening and closing of the mounting port;

[0010] The inner box structure comprises an inner box body, an inner box cover and a plurality of condensing plates; the inner box body has a storage space inside, and the storage space is formed with a storage opening on one side of the inner box body; the inner box cover is movably connected with the inner box body, and the inner box cover can control the opening and closing of the storage opening; the condensing plates are arranged on the inner wall of the storage space;

[0011] A plurality of the temperature adjusting devices correspond to a plurality of the condensing plates one by one, and the temperature adjusting devices are located on the side of the corresponding condensing plates close to the storage space;

[0012] The temperature adjusting device comprises a bag body, a seat body, an ignition element and a temperature sensing element; the bag body and the seat body are arranged on the corresponding condensing plate, and the seat body is connected with the bag body; the bag body has an inner cavity inside, and the bag body is filled with combustible material in the inner cavity; the ignition element is arranged on the side of the seat body close to the bag body and partially located in the inner cavity, which can ignite the combustible material in the inner cavity; the temperature sensing element is arranged on the side of the seat body close to the storage space, and the temperature sensing element is signal connected with the corresponding ignition element.

[0013] By adopting the above technical scheme, when the temperature sensing element senses that the temperature around it in the storage space is lower than a certain value (i.e. does not reach the temperature range required for keeping the goods low), the corresponding ignition element can ignite the combustible material in the corresponding bag body. The combustible material can release heat during combustion, which can increase the temperature of the low-temperature area of the storage space, so that the temperature in the storage space can be kept within the range suitable for preserving goods, so that the cold chain turnover box can adjust the refrigeration effect on the goods stored in it according to the temperature change in it, so as to ensure the quality of the goods.

[0014] Optionally, the combustible material is a mixed gas of hydrogen and oxygen with a proper ratio.

[0015] By adopting the above technical scheme, the safety of the combustible material combustion process can be improved, the cost required for filling the combustible material can be reduced, and the harm caused by the combustible material combustion to the environment can be reduced.

[0016] Optionally, the bag body has elasticity; when the inner cavity is filled with the combustible material, the bag body is in an inflated state; after the combustible material is burned, the bag body shrinks.

At the same time, after the bag is impacted by the articles, the combustible substance in the inner cavity of the bag can be mixed more uniformly, thereby further improving the safety during the combustion of the combustible substance.

[0021] Optionally, a sealing ring is arranged on the inner box cover, and when the inner box cover closes the storage port, the sealing ring abuts against the inner box body.

[0022] By using the above technical solution, the sealing effect of the inner box cover on the storage space can be improved, and when the inner box cover is installed on the inner box body, the pressure in the storage space decreases during the contraction of the bag caused by the combustion of the combustible substance in the inner cavity of the bag, which can further improve the sealing effect of the inner box cover on the storage space, thereby further reducing the probability of the temperature in the storage space being affected by the outside world.

[0024] By using the above technical solution, when the temperature in the storage space increases due to the combustion of the combustible substance, if the temperature sensing element senses that the temperature in the storage space and its surrounding is higher than a certain value (i.e. exceeds the temperature range required for the articles to be kept), the first valve body will control the exhaust pipe to be communicated, so that the substance in the inner cavity can be discharged through the exhaust pipe, and the temperature adjusting device will stop affecting the heating and warming of the storage space, thereby strengthening the refrigeration effect of the condenser plate on the storage space, and further improving the keeping effect of the articles in the storage space.

[0025] Optionally, the seat body is located at the position of the storage space far from the storage port, and the end of the exhaust pipe far from the inner cavity is communicated with the installation space.

[0026] By adopting the technical scheme, the substances in the inner cavity can be conveniently discharged through the discharge pipes, and the influence of the substances on the environment outside the cold chain turnover box after being discharged can be reduced.

[0027] Optionally, the outer box body is provided with a plurality of grooves on the inner wall of the mounting space, and the plurality of ends of the discharge pipes away from the inner cavity are communicated with the plurality of grooves respectively after the inner box structure is mounted in the mounting space.

[0028] By adopting the technical scheme, the substances discharged from the discharge pipes can be temporarily stored in the mounting space, so that the probability of the substances polluting the mounting space can be reduced.

[0029] Optionally, the temperature adjusting device further comprises a filling pipe and a second valve body; the filling pipe is arranged in the inner part of the seat body, and the second valve body is arranged in the inner part of the filling pipe; the two ends of the filling pipe are communicated with the inner cavity and the outer side space of the inner box body respectively, and the second valve body can control whether the filling pipe is communicated.

[0030] By adopting the technical scheme, the user can conveniently fill the combustible substances into the bag body, so that the bag body in the temperature adjusting device can be reused.

[0044] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0045] Reference Figure 1 This application discloses a cold chain turnover box with temperature regulation function, which is used for low-temperature preservation of goods and facilitates the transportation of goods that require low-temperature preservation.

[0046] Reference Figure 2 and Figure 3 The cold chain turnover box includes an outer box structure 1, an inner box structure 2, and several temperature control devices 3. The outer box structure 1 protects the inner box structure 2 and improves the insulation effect of the cold chain turnover box.

The temperature control devices 3 adjust the refrigeration effect on the items stored inside the cold chain turnover box according to changes in the surrounding temperature, ensuring the items are stored within a suitable temperature range and effectively guaranteeing their quality.

[0047] The outer box structure 1 is a cuboid structure as a whole, comprising an outer box body 11, an outer box cover 12 and a plurality of buffer members 13.

[0048] The outer box body 11 is a cuboid structure as a whole, and has an installation space 111 adapted to the inner box structure 2 inside. The installation space 111 is also a cuboid structure, and the length direction and the width direction of the installation space 111 are parallel to the length direction and the width direction of the outer box body 11 respectively. Moreover, the installation space 111 is provided with an installation opening 112 on one side of the width direction of the outer box body 11, through which the inner box structure 2 can enter or exit the installation space 111.

[0049] The outer box cover 12 is a long rectangular plate structure as a whole, and is movably installed on one side of the width direction of the outer box body 11, and is located on one side of the outer box body 11 at the position of the installation opening 112.

When the outer box cover 12 is rotated to the limit position away from the installation opening 112, the installation opening 112 is in an open state at this time, and the inner box structure 2 can conveniently enter or exit the installation space 111 through the installation opening 112. In this embodiment, the outer box cover 12 is preferably provided with a lock. When the outer box cover 12 is rotated to the limit position towards the installation opening 112, the outer box cover 12 can be fixedly connected to the outer box body 11 through the lock. Since the lock with the above function is a common prior art, it will not be described here, and it is omitted in the drawings.

[0051] The buffer member 13 is a long rectangular sheet structure as a whole, and is fixedly installed on the inner wall of the installation space 111. A plurality of buffer members 13 cover the inner wall of the top and the horizontal side of the installation space 111 respectively. In this embodiment, the buffer member 13 is preferably made of rubber material.

[0052] Further, the outer box cover 12 is also preferably fixedly installed with a buffer member 13. When the outer box cover 12 covers the installation opening 112, the buffer member 13 is located on the side of the outer box cover 12 close to the installation space 111.

[0053] Reference Figure 1 and Figure 3, the inner box structure 2 is also cuboid structure, and the size of the inner box structure 2 is matched with the size of the installation space 111. When the inner box structure 2 is installed in the installation space 111, the length direction and the width direction of the inner box structure 2 are parallel to the length direction and the width direction of the outer box body 11 respectively, the bottom end surface of the inner box structure 2 is abutted with the bottom inner wall of the installation space 111, and the top and the peripheral surface of the inner box structure 2 are contacted with the buffer 13 (including the buffer 13 installed on the outer box cover 12) at the same time. In the embodiment, preferably, after the inner box structure 2 is installed in the installation space 111, the buffer 13 contacted with the inner box structure 2 is in the state of being extruded and deformed, so as to effectively improve the position stability of the inner box structure 2 in the installation space 111.

[0054] Referring to Figure 3 and Figure 4 , the inner box structure 2 includes an inner box body 21, an inner box cover 22, a plurality of condensation plates 23 and a plurality of temperature adjusting devices 3.

[0055] The inner box body 21 is cuboid structure, and the inside of the inner box body 21 has a storage space 211 for storing the items to be stored at low temperature. The shape of the storage space 211 is also cuboid structure, and the length direction and the width direction of the storage space 211 are parallel to the length direction and the width direction of the inner box body 21 respectively. In addition, the storage space 211 is formed with a storage port 212 for the items to be stored at low temperature to enter or exit the storage space 211 through one side of the height direction of the inner box body 21.

[0056] The inner box cover 22 is long rectangular plate structure, and is movably installed on one side of the height direction of the inner box body 21 and located on one side of the inner box body 21 at the position of the storage port 212. In the embodiment, preferably, the inner box cover 22 is movably connected with the inner box body 21 in a detachable manner, and the inner box cover 22 is movably connected with the inner box body 21 in a detachable manner by being partially embedded and covered.

[0057] After the inner box cover 22 is installed on the inner box body 21, the storage port 212 can be closed, so that the storage space 211 is a sealed space, and at this time, the length direction and the width direction of the inner box cover 22 are parallel to the length direction and the width direction of the inner box body 21 respectively. In the embodiment, preferably, the inner box cover 22 also has a lock, and when the inner box cover 22 closes the storage port 212, the inner box cover 22 can be fixedly connected with the inner box body 21 through the lock. Since the lock with the above function is a common prior art, it is not described here, and it is omitted in the drawings.

[0058] Further, in order to improve the sealing effect of the inner box cover 22 on the storage space 211, preferably, a sealing ring 221 is fixedly installed on one side of the inner box cover 22.

[0059] The sealing ring 221 is annular in whole and is distributed around the two length edges and the two width edges of the inner box cover 22. When the inner box cover 22 is installed to close the storage opening 212, the sealing ring 221 can be in close contact with the inner box body 21, so that the gap between the inner box cover 22 and the inner box body 21 has high sealing performance. In the embodiment, the sealing ring 221 is preferably elastic, and is preferably in a squeezed state, which can effectively reduce the probability of gas exchange between the storage space 211 and the outside.

[0060] The inner box structure 2 is installed in the installation space 111 in a position state with the storage opening 212 facing upward, and after the inner box structure 2 is installed in the installation space 111, the inner box cover 22 will be kept in abutment with the inner box body 21 under the action of the adjacent buffer 13.

[0061] The condensing plate 23 is rectangular in whole and can be fixedly installed on the rectangular inner wall of the storage space 211 in a covering manner, and a plurality of condensing plates 23 are fixedly installed on the plurality of inner walls of the storage space 211. In the embodiment, the inner box structure 2 preferably includes four condensing plates 23, and when the storage opening 212 of the inner box body 21 faces upward, the four condensing plates 23 are located on the four inner walls of the storage space 211 in the horizontal direction. The condensing plate 23 can reduce the temperature in the storage space 211 by circulating the internal refrigerant, and since the condensing plate 23 is prior art in the field, it will not be described here, and it is only briefly shown in the drawings.

[0062] Referring to Figure 4 and Figure 5 , a plurality of temperature adjusting devices 3 correspond to a plurality of condensing plates 23 one by one, and the temperature adjusting device 3 is installed on the side of the corresponding condensing plate 23 close to the storage space 211. In the embodiment, correspondingly, the inner box structure 2 preferably includes four temperature adjusting devices 3.

[0063] The temperature adjusting device 3 includes a seat body 31, a bag body 32, an ignition member 33, a temperature sensing member 34, a discharge pipe 35, a filling pipe 36, a first valve body 37, and a second valve body 38.

[0064] The seat body 31 and the bag body 32 are fixedly installed on the side of the corresponding condensing plate 23 close to the storage space 211, and the seat body 31 is located at one end of the condensing plate 23 away from the storage opening 212. The bag body 32 covers the surface of the corresponding condensing plate 23 and is fixedly connected with the corresponding seat body 31, and the bag body 32 has an inner cavity 321 in the inside, and the inner cavity 321 is filled with combustible substance 4. In the embodiment, the combustible substance 4 is preferably a hydrogen-oxygen mixed gas with a proper ratio (i.e., a mixed gas with a stoichiometric ratio of hydrogen to oxygen of 2:1).

[0065] The bag body 32 is elastic, and expands after the inner cavity 321 is filled with the combustible substance 4, at which time the bag body 32 as a whole is in a rectangular plate structure that is adapted to the size of the corresponding condensing plate 23; and shrinks after the inner cavity 321 is emptied, at which time the bag body 32 as a whole is in a rectangular sheet structure that is adapted to the size of the corresponding condensing plate 23.

[0066] The ignition element 33 is fixedly installed inside the seat body 31, at the end of the seat body 31 that is close to the corresponding bag body 32, and part of the ignition element 33 penetrates through the seat body 31 and is located in the inner cavity 321 corresponding to the ignition element 33. The ignition element 33 can be controlled by a signal to ignite the combustible substance 4 in the inner cavity 321, and the combustible substance 4 will release heat and generate water after being burned.

[0067] The temperature sensing element 34 is fixedly installed on the surface of the seat body 31, at the side of the seat body 31 that is close to the storage space 211, and can sense the temperature of the ambient environment in the storage space 211. In this embodiment, the temperature sensing element 34 is preferably a temperature sensor; since the temperature sensor is a common prior art, it will not be described here, and only a brief representation is made in the drawings.

[0068] The discharge pipe 35 is fixedly installed inside the seat body 31, one end of the discharge pipe 35 communicates with the inner cavity 321 of the corresponding bag body 32, and the other end of the discharge pipe 35 penetrates through the inner box body 21 away from the storage port 212 and communicates with the outside, so that the inner cavity 321 of the corresponding bag body 32 can communicate with the space outside the inner box body 21 through the discharge pipe 35.

[0069] The first valve body 37 is fixedly installed inside the corresponding discharge pipe 35, and can control whether the corresponding discharge pipe 35 is communicated, and in the normal state, keeps the discharge pipe 35 in a blocked state. In this embodiment, the first valve body 37 is preferably a servo valve; since the servo valve is a common prior art, it will not be described here, and only a brief representation is made in the drawings.

[0070] The filling pipe 36 is also fixedly installed inside the seat body 31, one end of the filling pipe 36 communicates with the inner cavity 321 of the corresponding bag body 32, and the other end of the filling pipe 36 penetrates through the inner box body 21 and communicates with the outside at the side adjacent to the corresponding bag body 32, so that the inner cavity 321 of the corresponding bag body 32 can also communicate with the space outside the inner box body 21 through the filling pipe 36. In this embodiment, one end of the filling pipe 36 communicates with the inner cavity 321 of the corresponding bag body 32 through the discharge pipe 35, and the position where the filling pipe 36 communicates with the discharge pipe 35 is located at the side of the first valve body 37 that is close to the inner cavity 321 of the corresponding bag body 32.

[0071] The second valve body 38 is fixedly installed in the interior of the corresponding filling pipe 36, and can control whether the corresponding filling pipe 36 is communicated, and normally keeps the filling pipe 36 in a closed state. In the embodiment, the second valve body 38 is preferably a manual valve; since the manual valve is a common prior art, it is not described here, and only a brief representation is made in the drawing.

[0072] After the user controls the second valve body 38 to open, the combustible substance 4 can be filled into the inner cavity 321 of the corresponding bag body 32 through the filling pipe 36 outside the inner box 21, so that the corresponding bag body 32 is inflated, and then the second valve body 38 is controlled to close, so that the bag body 32 can keep the state of being inflated due to the filling of the inner cavity 321 by the combustible substance 4.

[0073] In the same temperature adjusting device 3, the ignition element 33 and the first valve body 37 are both in signal connection with the temperature sensing element 34, and the temperature sensing element 34 can control the corresponding ignition element 33 and the corresponding first valve body 37 according to the temperature it senses.

[0074] When the article is stored in the storage space 211, the four condensing plates 23 can play a refrigeration effect on the article through the respective corresponding temperature adjusting device 3, so that the article is stored at a low temperature; when the temperature sensing element 34 senses that the temperature around it in the storage space 211 is lower than the suitable temperature range for low-temperature storage of the article, at this time the temperature sensing element 34 will control the corresponding ignition element 33 to ignite the combustible substance 4 filled in the inner cavity 321 of the corresponding bag body 32, and the combustible substance 4 releases heat in the process of burning, so as to increase the temperature around the temperature sensing element 34 in the storage space 211, so that the overall temperature in the storage space 211 is suitable for the storage of the article; when the temperature sensing element 34 senses that the temperature around it in the storage space 211 is higher than the suitable temperature range for low-temperature storage of the article, at this time the temperature sensing element 34 will control the corresponding first valve body 37 to open, so that the substance in the inner cavity 321 of the bag body 32 can be discharged through the discharge pipe 35, effectively reducing the influence of the combustion of the combustible substance 4 on the temperature of the storage space 211, so as to reduce the temperature around the temperature sensing element 34 in the storage space 211, so that the overall temperature in the storage space 211 remains suitable for the storage of the article.

[0075] Further, it is preferred that the inner wall surface of the storage space 211 of the inner box 21 away from the storage port 212 is smooth, that is, the friction between the article and the surface is small, so that when the article has a tendency to move in the storage space 211, it can slide along the surface. In the process of sliding along the surface, the article can contact the surrounding bag bodies 32, and the elasticity of the bag bodies 32 can effectively reduce the probability of damage caused by the article bumping. At the same time, when the article hits the bag body 32, the combustible substance 4 filled in the corresponding inner cavity 321 can be mixed more uniformly, improving the safety of subsequent combustion of the combustible substance 4.

[0076] Further, when the combustible substance 4 in the inner cavity 321 of the bag body 32 is combusted, the bag body 32 will shrink, so as to reduce the space occupied by the bag body 32 in the storage space 211, thereby reducing the air pressure in the storage space 211; at this time, due to the air pressure difference between the inside and outside of the inner box structure 2, the abutting force of the inner box cover 22 to the inner box body 21 is increased, thereby further improving the sealing effect of the inner box cover 22 to the storage space.

[0077] Further, in order to reduce the influence of the substance in the inner cavity 321 of the bag body 32 on the internal environment of the installation space 111 after being discharged through the discharge pipe 35, it is preferred that the outer box body 11 is provided with a groove 113 on one side of the outer box body 11 in the height direction of the installation space 111, and the groove 113 is used for temporarily storing the substance after being discharged, and it is preferred that the groove 113 is kept at the position of the bottom of the outer box body 11 during the transportation of the cold chain turnover box.

[0078] When the inner box structure 2 is installed in the installation space 111, the end of each discharge pipe 35 away from the corresponding inner cavity 321 can communicate with the groove 113, so as to effectively ensure that the substance in the inner cavity 321 of the bag body 32 can be temporarily stored in the groove 113 after being discharged through the discharge pipe 35.

[0079] The implementation principle of the cold chain turnover box with the temperature adjusting function in the embodiment of the present application is as follows:

[0080] During the process of storing the low-temperature preserved articles in the cold chain turnover box, the condenser plate 23 can continuously play a refrigeration effect on the storage space 211, so that the articles are preserved at low temperature.

[0081] When the temperature sensing member 34 senses that the temperature around the temperature sensing member 34 in the storage space 211 is lower than the suitable temperature range for low-temperature preservation of the articles, the temperature sensing member 34 controls the corresponding ignition member 33 to ignite the combustible substance 4 in the inner cavity 321 of the corresponding bag body 32, and the combustible substance 4 releases heat during the combustion process, so that the temperature around the temperature sensing member 34 in the storage space 211 is increased, and the temperature in the storage space 211 is kept suitable for preserving the articles.

[0082] During the combustion process of the combustible substance 4 or after the combustion of the combustible substance 4, when the temperature sensing member 34 senses that the temperature around the temperature sensing member 34 in the storage space 211 is higher than the suitable temperature range for low-temperature preservation of the articles, the temperature sensing member 34 controls the corresponding first valve body 37 to open, so that the substance in the inner cavity 321 of the corresponding bag body 32 can be discharged to the groove 113 through the discharge pipe 35, the influence of the combustible substance 4 on the temperature in the storage space 211 is reduced, the temperature around the temperature sensing member 34 in the storage space 211 is decreased, and the temperature in the storage space 211 is continuously kept suitable for preserving the articles.

[0083] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
