Technical Field

[0001] This utility model relates to the field of flower preservation technology, and in particular to a fresh-cut rose preservation box. Background Technology

[0002] Fresh-cut roses are susceptible to temperature fluctuations, changes in the gas environment, and mechanical damage during transportation and storage, leading to browning of petals, mold growth, and wilting due to dehydration. Existing packaging technologies have the following shortcomings:

[0003] Traditional cardboard boxes or single insulated boxes lack controlled atmosphere functionality, making it impossible to regulate oxygen and carbon dioxide concentrations and thus difficult to suppress flower respiration and ethylene synthesis.

[0004] Ordinary refrigeration equipment lacks real-time environmental monitoring and early warning mechanisms, making it impossible to detect and intervene in abnormalities in temperature, humidity, and gas concentration in a timely manner.

[0005] Fresh-cut flowers are easily damaged by compression when stacked in boxes during transportation, and the lack of comprehensive preservation methods results in a short shelf life and high loss rate. Therefore, there is an urgent need for a multi-functional and synergistic preservation box to solve the problems of insufficient environmental control and inadequate physical protection in existing technologies, and to improve the circulation and preservation effect of fresh-cut roses. Utility Model Content

By integrating components such as modified atmosphere, low-temperature maintenance, monitoring, lighting, and shock absorption, this invention forms a multi-functional and synergistic preservation system, effectively solving problems such as insufficient environmental control and lack of physical protection in existing technologies, and improving the circulation and preservation effect of fresh-cut roses.

[0007] The technical solution to the technical problem solved by this utility model is as follows:

[0008] This application provides a fresh-cut rose preservation box, including a box body and a box lid;

[0009] The lid of the chamber has multiple ventilation holes evenly spaced out, and the ventilation holes are covered with a silicone window film to regulate the oxygen and carbon dioxide concentration inside the chamber.

[0010] The chamber contains a detection component, an atomizer, an ice pack compartment, and a fan. The detection component includes a temperature and humidity sensor, an ethylene sensor, and a carbon dioxide sensor. The ice pack compartment is located in the middle of the chamber, with its opening facing upwards and containing ice packs. The atomizer is located inside the chamber and stores a preservative.

[0011] The inner walls of the lid and body of the box are each equipped with a blue light strip.

[0012] As an improvement to the above solution, an external wireless communication device and a control device are also included. The wireless communication device is connected to the detection component and the control device via a data cable and communicates with the mobile terminal. The data of the detection component is transmitted to the control device via the wireless communication device. The control device is used to compare the data detected by the detection component with a preset threshold, and to control the mobile terminal to issue an early warning when the comparison result is abnormal.

[0013] As an improvement to the above solution, a buzzer and a warning light are provided on the outer wall of the enclosure, both of which are electrically connected to the control device. The control device is also used to compare the data detected by the detection component with a preset threshold, and to control the buzzer and warning light to issue an early warning when the comparison result is abnormal.

[0014] As an improvement to the above solution, a shock-absorbing pad is laid on the bottom surface of the box.

[0015] As an improvement to the above solution, the box body and the box cover are detachably connected by a snap-fit ​​structure.

[0020] As an improvement to the above solution, the box is provided with horizontal and vertical partitions connected to its inner wall to form multiple independent placement areas; the ice pack compartment is set on the vertical partition, and both the ice pack compartment and the partition are provided with through holes evenly.

[0021] Compared with existing technologies, the above solution has the following advantages or beneficial effects:

[0022] Modified atmosphere preservation and environmental control: The ventilation holes covered with a silicone window film regulate oxygen and carbon dioxide concentrations, reducing the respiration of cut flowers; the nano-antibacterial coating and chlorine dioxide slow-release agent effectively inhibit microbial growth; the blue light strip and 1-methylcyclopropene inhibit ethylene synthesis and delay flower senescence.

[0023] Intelligent monitoring and early warning: The detection components monitor environmental parameters in real time and enable remote monitoring through wireless communication devices and mobile terminals, issuing early warning information in a timely manner so that users can keep track of the condition inside the refrigerator.

[0024] Physical protection and temperature control: dividers prevent flowers from being crushed and damaged, shock-absorbing pads reduce the impact of vibration, and ice packs and double-layer insulation structure lower the ambient temperature and reduce the damage of high temperature to flowers.

[0031] Example 1

[0032] This embodiment provides a fresh-cut rose preservation box, the main body of which includes a box body 1 and a box lid 2. The box body 1 is made of double-layer heat insulation material, with an inner layer of PP material and an outer layer of polyurethane. The two layers are tightly bonded together by a hot-pressing process to form a heat insulation layer of uniform thickness, effectively blocking the influence of external temperature on the internal environment of the box body 1. The inner PP material of the box body 1 is laminated with a high-barrier modified atmosphere film (such as ethylene-vinyl alcohol copolymer EVOH) and coated with a nano-antibacterial coating. The high-barrier modified atmosphere film can block the penetration of external oxygen and water vapor, and the nano-antibacterial coating is evenly distributed on the inner wall surface of the box body 1 to inhibit the growth of microorganisms. The box lid 2 is detachably connected to the box body 1 by a snap-fit ​​structure set around the perimeter, ensuring sealing performance while facilitating opening and closing. The overall dimensions of the box body 1 are 90cm-100cm in length, 50cm-60cm in width, and 50cm-60cm in height, and it can hold 600-800 fresh-cut roses.

[0033] The top of the lid has ten evenly distributed ventilation holes, each covered with a silicone window film to form a breathable silicone window. The silicone window film is made of a material with high oxygen permeability and appropriate carbon dioxide permeability, used to regulate oxygen and carbon dioxide concentrations, thereby creating a suitable modified atmosphere environment for preserving fresh-cut roses. Under normal circumstances, it can maintain an oxygen concentration of 3%-4% and a carbon dioxide concentration of 10%-12% inside the preservation box.

[0034] The detection assembly 3 is fixedly installed on the top of the inner wall of the cabinet 1, including a temperature and humidity sensor (DHT22, accuracy ±0.5℃ / ±3%RH), an ethylene sensor (MQ-2), and a carbon dioxide sensor (NDIR). The temperature and humidity sensor is used to monitor the temperature and relative humidity inside the refrigerator in real time, the ethylene sensor has a detection range of 0-100ppm, and the carbon dioxide sensor has a range of 0-5000ppm.

[0035] The interior of the container 1 is divided into four independent storage areas by a horizontal and a vertical partition 5. Each area is sized to fit a bunch of fresh-cut roses, preventing the flowers from being crushed or damaged. The partition 5 is made of lightweight, high-strength plastic, and the front and back walls of the container 1 have slots into which the edges of the partition 5 are secured. Each partition 5 has evenly spaced perforations to allow cold air to diffuse evenly throughout the entire container.

[0036] An ice pack compartment 10 is installed on the longitudinal partition plate 5 inside the box 1. The ice pack compartment 10 can be fixed to the longitudinal partition plate 5 by a slot structure or other connecting structure. The ice pack compartment 10 has a cuboid structure with its opening facing upwards, making it easy to place and remove ice packs. The walls of the ice pack compartment 10 have evenly spaced through holes to allow cold air to diffuse throughout the entire refrigerator. Depending on the quantity of fresh-cut roses, an appropriate number of ice packs can be placed inside the compartment. The melting of the ice packs absorbs heat, reducing the impact of high temperatures during transportation on the fresh-cut roses and maintaining a low-temperature environment inside the box.

[0037] Blue light strips 8, specifically LED blue light strips 8, are installed on the inner side of the lid 2 and the inner wall of the box body 1, emitting blue light with a wavelength of 440-460nm. Blue light can inhibit ethylene synthesis in fresh-cut roses, delay flower maturation, and partially inhibit mold growth, thus extending the shelf life.

[0038] Two atomizers 9 are installed on the left and right sides of the bottom of the box 1. Specifically, these can be miniature ultrasonic atomizers 9 (100ml capacity, 5V voltage). Both atomizers 9 contain preservatives; specifically, one atomizer 9 contains 1-methylcyclopropene, and the other contains chlorine dioxide slow-release agent. In actual operation, the atomizers 9 atomize and release the preservatives into the preservation box.

[0039] Two fans 11 (5W power, 5V voltage) are symmetrically installed inside the box 1, located on both sides of the atomizer 9. The atomized gas is evenly distributed in the box by the rotation of the fan blades of the fan 11, ensuring that the fresh-cut roses in each placement area can come into contact with the preservative, inhibiting the release of ethylene from the flowers and controlling environmental microorganisms; it can also promote the even distribution of cold air in the ice pack compartment 10 in the box.

[0040] The bottom of the box 1 is entirely covered with a layer of shock-absorbing pads 6, which are made of elastic rubber and are glued to the bottom of the box 1. During transportation, the shock-absorbing pads 6 can absorb and buffer vibration energy, reducing damage to the fresh-cut roses.

[0041] Example 2

[0042] This embodiment is basically the same as Embodiment 1 above, except that:

[0043] This embodiment provides a fresh-cut rose preservation box, which also includes a control device, a wireless communication device 4, and a data transmission interface. The wireless communication device 4 integrates Wi-Fi 6 and Bluetooth 5.0 functional modules, is fixedly installed on the outer wall of the preservation box body 1, and has multiple data transmission interfaces.

[0044] The control device is electrically connected to the light strip, atomizer 9 and fan 11 respectively, and is used to control the normal operation of each component.

[0045] The detection component 3 is connected to the data transmission interface of the wireless communication device 4 via a data cable to realize the physical transmission of monitoring data from each sensor. The control device is located outside the housing 1, and its core control unit adopts an STM32F103C8T6 microcontroller. This control device is also connected to the data transmission interface of the wireless communication device 4 via a data cable to establish a data interaction channel.

[0046] The side wall of the container 1 has a suitable cable threading hole. When the data cable passes through the cable threading hole, it is sealed by a waterproof sealing ring to ensure the airtightness of the food storage container. At the same time, the data cable connecting the wireless communication device 4 and the control device is wrapped with a shielding layer to reduce electromagnetic interference.

[0047] The wireless communication device 4 is connected to a mobile terminal and receives environmental parameters inside the refrigerator detected by the detection component 3, as well as abnormal data signals sent by the control device, in real time.

[0048] In terms of early warning functionality, a buzzer and warning light are also installed on the surface of housing 1. The buzzer is a high-decibel piezoelectric buzzer, connected to the control device via a wire. When the control device, based on the STM32F103C8T6 microcontroller, determines that the data monitored by the detection component 3 exceeds the preset range (by comparing the sensor value with the preset threshold through the built-in ADC module), the control device sends an electrical signal to the buzzer, causing it to emit a continuous or intermittent buzzing sound, thus achieving a local audible warning.

[0049] The warning light is a bright red LED, also connected to the control device via wires. When abnormal data is detected, the control device drives the warning light to flash at high frequency as a local light signal warning. Simultaneously, after receiving the abnormal data signal from the control device, the wireless communication device 4 transmits the warning information to the mobile terminal, providing remote audible and visual warnings to remind the user to take timely action.

[0050] Regarding the input / output and control methods of the control device, wireless communication device 4, etc., involved in this embodiment, it is hereby declared that this embodiment only involves the utilization and improvement of its data communication structure and communication structure. Furthermore, the implementation of the aforementioned data communication, numerical comparison, and data communication based on the PLC control system is already existing technology. This embodiment does not intend to, nor does it involve, any improvement to the microcontroller control board itself, the microcontroller control program, or the computer program. Any existing microcontroller control technology that can realize the data communication, numerical comparison, and data communication functions of this embodiment should be applicable to this embodiment.

[0051] In this embodiment of the invention, all electrical devices are connected to a power system. The power system uses an 18650 lithium battery (3000mAh) with a USB-C fast charging interface. The lithium battery is installed in an independent battery compartment on the outside of the housing 1 and connected to each electrical device via wires. The battery compartment is equipped with an insulating partition to ensure electrical safety. The power system supports a low-power mode with a standby current of <0.1mA, effectively extending battery life. During charging, the lithium battery can be quickly charged by connecting to an external power source via the USB-C fast charging interface.

[0052] Application Examples

[0053] In use, freshly harvested cut roses are first pre-cooled using differential pressure. Pre-cooling is stopped once the flower core temperature drops to 1-2℃, and the flowers are placed in their respective compartments within the preservation box. The appropriate number of ice packs are placed in the ice pack compartment 10 according to the number of flowers. 1-Methylcyclopropene and chlorine dioxide slow-release agent are placed in the two miniature ultrasonic atomizers 9, respectively. The box lid 2 is then tightly closed and secured with clips. The LED blue light strip 8, miniature ultrasonic atomizers 9, and fan 11 are turned on for 1-2 hours of atomized fumigation, ensuring even distribution of the preservative gas within the box and inhibiting ethylene release and microbial growth. Simultaneously, the detection component 3 monitors the temperature, humidity, and ethylene and carbon dioxide gas concentrations within the box in real time, transmitting the data to a mobile terminal via the wireless communication device 4. During transportation, shock-absorbing pads 6 reduce vibration damage, double-layer insulation material and ice packs maintain a low-temperature environment, and breathable silicone windows regulate gas concentration, achieving modified atmosphere preservation.

[0054] When the data detected by the detection component 3 exceeds the preset suitable range (such as temperature exceeding 20℃, relative humidity below 60%, ethylene concentration above 20μL・L-1, carbon dioxide concentration above 20%, or oxygen concentration below 1%), the buzzer and warning light will issue an early warning, and the mobile terminal will also issue an early warning message to remind the user to handle the situation in a timely manner.

[0055] Tests showed that after the above-mentioned modified atmosphere, light, preservation and anti-corrosion treatments, fresh-cut roses can be circulated at 30℃ for 5-7 days, with the shelf life extended to 15 days. The petals showed no browning or rotting, and the water loss rate was reduced by more than 80% compared to traditional cardboard packaging.

[0056] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
