Description

Technical Field

[0001] This utility model relates to the field of storage and transportation box technology, specifically to a storage and transportation box with ventilation and temperature regulation capabilities. Background Technology

[0002] In daily life, products with high requirements for transportation and storage environments, such as live animals, need both a constant temperature environment and ventilation, meaning air circulation between the inside and outside of the container. For example, in the transportation of live seafood, it is essential to maintain the temperature and oxygen content inside the storage container to avoid losses caused by the weakening of the fish due to adverse conditions. To address the limitations of storage, transportation, and usage environments for products with high environmental requirements, such as live animals, some storage and transportation boxes with ventilation and temperature control capabilities have been proposed. For example, invention patent CN108782408A discloses an adaptive storage and transportation box, including a lid, a movable handle, a refrigerated transport box, box body buckles, and hinges. The lid is installed on the top of the refrigerated transport box, and the two are connected by hinges. Hinges are installed at the bottom of the lid. The movable handles are installed on both sides of the refrigerated transport box and are fixedly connected by an embedded method. By controlling the wind force of the fan device, the melting rate of ice is adjusted, further controlling the amount of cold air supplied. Due to the gravity of the cold water, a movable disc mechanism and a heating device heat the cold water to a temperature suitable for aquatic products, providing fresh water and improving the survival rate and freshness of the aquatic products, effectively reducing spoilage due to lack of oxygen. However, this device cannot provide cooling and heat dissipation for extended periods and cannot purify the air inside the storage and transportation box, resulting in limited practicality. Utility Model Content

[0003] The purpose of this invention is to provide a storage and transportation box with ventilation and temperature regulation capabilities, which solves the problems of existing technologies that cannot provide long-term cooling and heat dissipation and lack air purification capabilities.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A storage and transportation box with ventilation and temperature control capabilities includes a main body, an air handling unit disposed on one side of the main body, an air supply vent disposed on the top of the main body, and a return air vent disposed on the bottom of the main body. The air handling unit is used to regulate the temperature, purify, and / or control the negative pressure of the air. The air treated by the air handling unit enters the main body of the storage and transportation box through the air supply vent, and the air inside the main body of the storage and transportation box re-enters the air handling unit through the return air vent, forming an airflow circulation.

[0006] Preferably, the air handling assembly includes a cooling module, an air purification module, and a negative pressure control module. The cooling module is used to reduce the air temperature, the air purification module is used to filter and purify the air, and the negative pressure control module is used to control the airflow inside the main body of the storage and transportation box. The cooling module, the air purification module, and the negative pressure control module are all disposed in an auxiliary housing, which is disposed on one side of the main body of the storage and transportation box.

[0007] Preferably, the main body of the storage and transportation box includes a bottom plate, side plates, and a cover plate. The four side plates are arranged above the bottom plate, and the cover plate is movably positioned above the side plates.

[0008] Preferably, the air supply outlet is located at the top of the side panel of the housing, and the return air outlet is located at the bottom of the side panel of the housing.

[0009] Preferably, the negative pressure control module includes an air-generating cavity and a fan installed in the air-generating cavity. An exhaust valve and an air supply valve are installed at the top of the air-generating cavity. When the air supply valve is closed and the exhaust valve is opened, negative pressure is generated inside the main body of the storage and transportation box. When the air supply valve is opened and the exhaust valve is closed or shut off, there is no negative pressure inside the main body of the storage and transportation box.

[0010] Preferably, the cooling module includes a semiconductor cooling chip and a semiconductor heat sink, and the air blown out by the exhaust valve is discharged after passing through the semiconductor heat sink.

[0011] Preferably, the air purification module includes a filter, a plasma purifier, and an activated carbon block. The filter is used to filter particulate matter in the air discharged from the main body of the storage and transportation box; the plasma purifier is used to ionize oxygen molecules to generate oxygen ions; and the activated carbon block is used to adsorb residual odors in the airflow.

[0012] Preferably, the air outlet is a mesh or slit type.

[0013] Preferably, a power supply and a controller are provided within the air handling assembly, the power supply being used to power the air handling assembly.

[0014] Preferably, the filter screen is rotatably mounted in the additional housing via a first rotary drive, and the activated carbon block is rotatably mounted in the additional housing via a second rotary drive.

[0015] In this invention, the storage and transportation box has two working modes: breathing purification and temperature regulation. It can be used selectively according to working conditions. In the breathing temperature regulation mode, the airflow does not pass through the filter and activated carbon block, which can reduce airflow resistance, save energy, and improve the service life of the activated carbon adsorption block.

[0016] The airflow is cooled using semiconductor refrigeration, which has a simple structure, requires no compressor, and is easy to handle. When the air supply valve is closed and the exhaust valve is opened, the negative pressure inside the storage tank increases, preventing odors from escaping. Conversely, when maintaining negative pressure inside the storage tank is not required, the air supply valve can be opened wider and the exhaust valve closed or shut off. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1 to 8The storage and transportation box shown includes a main body 1, an air handling unit 2 on one side of the main body 1, an air supply vent 3 at the top of the main body 1, and a return air vent 4 at the bottom of the main body 1. Air processed by the air handling unit 2 enters the main body 1 through the air supply vent 3, and air inside the main body 1 re-enters the air handling unit 2 through the return air vent 4, forming an airflow circulation.

[0028] The main body 1 of the storage and transportation box includes a bottom plate 10, side plates 11, and a cover plate 12. The four side plates 11 are fixedly mounted on top of the bottom plate 10. The cover plate 12 is movably mounted on top of the side plates 11. The cover plate 12 can be connected to the top of the side plates 11 either by four sets of clips or by hinges and clips. The bottom plate 10, side plates 11, and cover plate 12 are all insulated panels, providing good thermal insulation.

[0029] Air supply vents 3 are located at the top of the side panel 11 of the housing, and return air vents 4 are located at the bottom of the side panel 11 of the housing. The air supply vents 3 and return air vents 4 are evenly distributed along the upper and lower parts of the four side panels 11, respectively, forming a circumference. The air supply vents 3 are mesh or slit-type. The airflow treated by the air handling unit 2 is delivered from the upper air supply vents 3, forming an air curtain to prevent odors from escaping from the main body of the storage and transportation box 1. After passing over the odorous items inside the main body of the storage and transportation box 1, the airflow enters the air handling unit 2 from the lower return air vents 4.

[0030] The air handling unit 2 is used for air temperature regulation, purification, and / or negative pressure control. The air handling unit 2 includes a cooling module 20, an air purification module 21, and a negative pressure control module 22. All three modules are housed within an auxiliary housing 23, which is located on one side of the storage and transportation box body 1. The auxiliary housing 23 is flush against the side panel 11 of the box body, forming a single unit with the storage and transportation box body 1.

[0031] The air handling unit 2 is also equipped with a power supply 24 and a controller 25. The power supply 24 is used to supply power to the electrical components in the air handling unit 2. The specific electrical components include the controller 25, the fan 221, the exhaust valve 222, the supply valve 223, the plasma purifier 211, the first rotary drive 213 and the second rotary drive 214. Of course, other electrical components are also powered by the power supply 24. The controller 25 controls the opening and closing of the fan 221, the opening and closing of the exhaust valve 222, the opening and closing of the supply valve 223, the opening and closing of the plasma purifier 211, the rotation of the first rotary drive 213 and the rotation of the second rotary drive 214.

[0032] The negative pressure control module 22 is used to control the airflow inside the storage and transportation box body 1. The negative pressure control module 22 includes an air-generating cavity 220 and a fan 221 installed inside the air-generating cavity 220. An exhaust valve 222 and an air supply valve 223 are installed at the top of the air-generating cavity 220. When the air supply valve 223 is closed and the exhaust valve 222 is opened, negative pressure is generated inside the storage and transportation box body 1. When the air supply valve 223 is opened and the exhaust valve 222 is closed or shut off, there is no negative pressure inside the storage and transportation box body 1. The air supply valve 223 blows air into the storage and transportation box body 1 through the air supply duct, and the exhaust valve 222 blows air out through the exhaust duct.

[0033] The cooling module 20 is used to reduce the air temperature. The cooling module 20 includes a thermoelectric cooler 200 and a thermoelectric heat sink 201. The thermoelectric cooler 200 is disposed within the air supply duct and cools the passing airflow. The thermoelectric heat sink 201 is disposed within the exhaust duct, adjacent to the exterior of the auxiliary housing 23. Air blown out by the exhaust valve 222 passes through the thermoelectric heat sink 201 before being discharged, improving heat dissipation and increasing the cooling efficiency of the thermoelectric cooler 200.

[0034] The air purification module 21 is used to filter and purify the air. The air purification module 21 includes a filter screen 210, a plasma purifier 211, and an activated carbon block 212. The filter screen 210 is located at the bottom of the auxiliary housing 23 and is used to filter particulate matter in the air discharged from the storage and transportation box body 1. The filter screen 210 is rotatably mounted in the auxiliary housing 23 via a first rotary drive component 213. The controller 25 can control the rotation of the first rotary drive component 213 to adjust the installation direction of the filter screen 210. The first rotary drive component 213 includes a stepper motor and a drive shaft fixedly mounted on the output end of the stepper motor. The filter screen 210 is fixedly mounted on the drive shaft, which is rotatably mounted in the auxiliary housing 23. When the controller 25 controls the stepper motor to rotate, the drive shaft drives the filter screen 210 to rotate.

[0035] Activated carbon block 212 is used to adsorb residual odors in the airflow. Activated carbon block 212 is rotatably mounted within the auxiliary housing 23 via a second rotary drive component 214. The controller 25 controls the rotation of the second rotary drive component 214 to adjust the installation direction of the activated carbon block 212. The second rotary drive component 214 includes a stepper motor and a drive shaft fixedly mounted on the output end of the stepper motor. The activated carbon block 212 is fixedly mounted on the drive shaft, which is rotatably mounted within the auxiliary housing 23. When the controller 25 controls the stepper motor to rotate, the drive shaft drives the activated carbon block 212 to rotate. The activated carbon block 212 is composed of three activated carbon adsorption blocks joined together. The end face of each activated carbon adsorption block is a parallelogram with an acute angle of 45°.

[0036] The plasma purifier 211 uses the ionization of oxygen molecules to generate a large number of oxygen ions. Utilizing the strong oxidizing effect of oxygen ions, harmful and odorous factors are oxidized and decomposed in a very short time, breaking the chemical bonds of volatile organic gases and ultimately generating harmless small molecules. These molecules are then adsorbed by activated carbon blocks 212 to achieve the purpose of purification.

[0037] The storage and transportation box has two working modes. One is the breathing purification and temperature control mode. In this mode, the activated carbon block 212 and the filter screen 210 are installed perpendicular to the airflow direction. The air discharged from the main body 1 of the storage and transportation box passes through the filter screen 210, the plasma purifier 211 and the activated carbon block 212 in sequence and enters the air generation cavity 220. Then it is discharged through the exhaust valve 222 and the exhaust duct, or it enters the main body 1 of the storage and transportation box through the air supply valve 223 and the air supply duct. At this time, the cooling module 20 cools down the air, forming a cycle.

[0038] The second mode is the breathing temperature regulation mode. In this mode, the activated carbon block 212 and filter screen 210 are installed parallel to the airflow direction. The air discharged from the main body 1 of the storage and transportation box passes through the plasma purifier 211 and directly enters the air-generating cavity 220. Then, it is discharged through the exhaust valve 222 and exhaust duct, or enters the main body 1 of the storage and transportation box through the air supply valve 223 and air supply duct. At this time, the cooling module 20 cools down the air, forming a circulation. In this state, the activated carbon block 212 and filter screen 210 do not increase the flow resistance of the airflow, saving energy and extending the service life of both.

[0039] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
