Abstract
Description
Technical Field
[0001] This utility model relates to the field of storage box technology, and in particular to a storage box temperature control system. Background Technology
[0002] Temperature-controlled storage boxes are generally used to properly preserve various items. Through temperature control, these boxes provide a stable and suitable environment for the stored items, effectively extending their shelf life or maintaining their specific condition.
[0003] Patent publication number CN221510662U discloses an intelligent fresh food packaging box, including: a box body, a refrigeration mechanism, a sensing mechanism, and a control system. Using this intelligent fresh food packaging box, the temperature inside the containment chamber is dynamically adjusted in real time through the control system to ensure the preservation effect of live fresh products. Secondly, the sealing lid effectively seals the containment chamber, further ensuring a constant temperature preservation state for live fresh products and reducing logistics transportation time. The overall packaging box is easy to handle and operate. Temperature changes can be recorded and fed back in real time during transportation, and the temperature change curve during transportation or after arrival at the destination can be viewed to determine the preservation of fresh products, thereby ensuring the preservation efficiency of live fresh products during transportation.
[0004] However, the patent relies solely on the vaporization of liquid compressed air to "provide the required oxygen," which is an indirect and passive oxygen supply method. For aquatic products with high oxygen consumption (such as fish and crabs), or in situations with long transportation times and high density, this method alone may not be able to maintain a sufficient dissolved oxygen concentration, posing a risk of oxygen deficiency. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a temperature control system for a storage box.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a temperature control system for a storage box, comprising a box body, a controller fixedly connected to the top surface of the box body, a heat preservation cavity provided in the box body, a door provided above the heat preservation cavity, the door being hinged to the top surface of the box body, an oxygen sensor provided inside the heat preservation cavity, the oxygen sensor being electrically connected to the controller, a chamber provided inside the box body, a miniature oxygen pump provided inside the chamber, the output end of the miniature oxygen pump being connected to an air pipe, the air pipe passing through the chamber and extending into the heat preservation cavity, and a one-way valve connected to the end of the air pipe, the one-way valve being fixed inside the heat preservation cavity.
[0007] A cooling chip, which is a semiconductor cooling chip, is fixedly connected to the bottom of the insulation cavity and is electrically connected to the controller.
[0008] A pump body is fixedly connected inside the insulation cavity. The output end of the pump body is connected to a delivery pipe, which extends into the cavity. The end of the delivery pipe is connected to an atomizer, which is fixed inside the cavity. The output end of the atomizer is connected to an output pipe, which passes through the cavity. A nozzle is fixedly connected inside the insulation cavity and is connected to the output pipe. A humidity sensor is fixedly connected to the bottom wall of the door. The humidity sensor, the pump body, and the atomizer are all electrically connected to the controller.
[0009] The insulation cavity is equipped with a perforated plate, and a support column is vertically fixed to the bottom surface of the perforated plate. The support column is attached to the top surface of the cooling chip, and a sponge pad is provided on the top surface of the perforated plate.
[0010] The cavity contains a storage battery, and a charging port is fixedly connected to the side of the storage battery, with the charging port penetrating the cavity.
[0011] Handles are hinged to both sides of the box.
[0012] An electronic lock is embedded in the side wall of the enclosure, and a lock hole adapted to the electronic lock is opened on the side of the enclosure door.
[0013] This utility model has the following beneficial effects: 1. Compared with existing technologies, this preservation box temperature control system, by introducing a combination of oxygen sensors and micro oxygen pumps, achieves real-time monitoring and active intervention of dissolved oxygen concentration inside the box. When the sensor detects that the oxygen concentration is lower than the critical value for the survival of live seafood, the controller will immediately start the oxygen pump to directly supplement oxygen to the water or sealed space through the air pipe and one-way valve, fundamentally solving the problem of death caused by lack of oxygen during transportation, and greatly improving the survival rate of live aquatic products (such as fish and crabs). The added humidity control module (pump body, atomizer, nozzle and humidity sensor) can automatically humidify and spray according to the environment inside the box, effectively preventing product moisture loss and quality decline caused by dry air, especially suitable for humidity-sensitive fruits and vegetables. This "temperature-oxygen-humidity" three-in-one intelligent closed-loop control provides a customized and comprehensive life-sustaining environment for different types of fresh products.
[0014] 2. Compared with existing technologies, the temperature control system of this storage box, with its combined design of a perforated plate, support column, and sponge pad, not only physically isolates the goods from the refrigeration unit, preventing localized overfreezing damage, but also allows the sponge pad to evenly distribute moisture and act as a buffer, improving transport stability. The built-in battery and charging port ensure continuous operation even when the system is disconnected from external power (such as during handling and loading), guaranteeing continuous environmental control and avoiding quality risks caused by power outages. The addition of an electronic lock enhances security during transport, preventing accidental opening of the box door. Handles on both sides make handling more convenient. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Reference Figures 1 to 4The temperature control system of this storage box includes a box body 1, a controller 2 fixedly connected to the top surface of the box body 1, a heat preservation chamber 5 in the box body 1, a door 3 above the heat preservation chamber 5, the door 3 being hinged to the top surface of the box body 1, an oxygen sensor 8 inside the heat preservation chamber 5, the oxygen sensor 8 being electrically connected to the controller 2, a cavity 11 inside the box body 1, a miniature oxygen pump 10 inside the cavity 11, the output end of the miniature oxygen pump 10 being connected to an air pipe 22, the air pipe 22 passing through the cavity 11 and extending into the heat preservation chamber 5, the end of the air pipe 22 being connected to a one-way valve 21, the one-way valve 21 being fixed inside the heat preservation chamber 5, handles 4 being hinged to both sides of the box body 1, an electronic lock 16 being embedded in the side wall of the box body 1, and a lock hole adapted to the electronic lock 16 being opened on the side of the door 3; A pump body 20 is fixedly connected inside the heat preservation chamber 5. The output end of the pump body 20 is connected to a delivery pipe 14, which extends into the chamber 11. The end of the delivery pipe 14 is connected to an atomizer 15, which is fixed inside the chamber 11. The output end of the atomizer 15 is connected to an output pipe, which passes through the chamber 11. A nozzle 17 is fixedly connected inside the heat preservation chamber 5 and is connected to the output pipe. A humidity sensor 19 is fixedly connected to the bottom wall of the door 3. The humidity sensor 19, the pump body 20, and the atomizer 15 are all electrically connected to the controller 2. A cooling chip 6 is fixedly connected to the bottom of the insulation cavity 5. The cooling chip 6 is a semiconductor cooling chip 6 and is electrically connected to the controller 2. A temperature sensor is fixedly connected to the bottom surface of the door 3. The temperature sensor is electrically connected to the controller 2. The heat preservation cavity 5 is provided with a sluice plate 9. A support column 7 is vertically fixed to the bottom surface of the sluice plate 9. The support column 7 is attached to the top surface of the cooling chip 6. A sponge pad 18 is provided on the top surface of the sluice plate 9. A storage battery 12 is installed inside the cavity 11. A charging port 13 is fixedly connected to the side of the storage battery 12 and passes through the cavity 11.
[0019] Working principle: During use, water is added to the insulation chamber 5 until the water level covers the top surface of the perforated plate 9. Then, a sponge pad 18 is placed on the perforated plate 9. Next, the controller 2 activates the cooling element 6, which cools the chamber until the temperature inside the insulation chamber 5 reaches the set value. The seafood is then placed on the sponge pad 18, and the door 3 is closed and locked using the electronic lock 16. Simultaneously, the oxygen sensor 8 monitors the oxygen content inside the insulation chamber 5 in real time. When the oxygen content is low, the controller 2 immediately activates the oxygenation pump, directly supplementing oxygen into the water through the air pipe 22 and the one-way valve 21, fundamentally solving the transportation problem. The system significantly improves the survival rate of live aquatic products (such as fish and crabs) by addressing the mortality problem caused by oxygen deficiency. Simultaneously, humidity sensor 19 monitors the humidity within the insulation chamber 5 in real time. When the humidity is too low, controller 2 activates pump 20, which delivers water through delivery pipe 14 to atomizer 15. Atomizer 15 atomizes the water and sends it through output pipe to nozzle 17, which then sprays it onto the seafood, maintaining humidity within the insulation chamber 5. The diffuser plate 9 and support column 7 form an elevated layer, separating the product storage area from the cooling element 6 below, preventing localized frostbite caused by direct contact between the product and the cold source. A sponge pad 18 is laid on the diffuser plate 9, absorbing and evenly distributing moisture (for aquatic products) while also providing cushioning and shock absorption, protecting the products from collision damage during transportation.
