Description

Technical Field

[0001] This utility model belongs to the field of agricultural technology and experimental device technology, specifically relating to an adjustable environmental growth box for studying sunburn in citrus fruits. Background Technology

[0002] Citrus sunburn is a phenomenon caused by strong radiation and high temperature stress, resulting in damage to the fruit peel tissue and severely affecting fruit quality. Studies have shown that the occurrence of sunburn is closely related to the intensity of radiation received by the fruit surface, ambient temperature, humidity, and other conditions. However, traditional field experiments struggle to precisely control these environmental parameters, posing significant challenges to researching the formation mechanism of citrus sunburn.

[0003] Currently, there are no experimental devices specifically designed for studying sunburn in citrus fruits. Existing environmental simulation equipment is mostly general-purpose environmental control devices with limited functionality, large size, and high energy consumption. For example, they can only control a single temperature variable, making it difficult to meet the requirements of complex environmental simulations; their bulky structure makes installation inconvenient, and no environmental simulators specifically designed for fruit trees or specific tissues have been reported, making it difficult to realistically simulate changes in the microenvironment of citrus fruits in experiments. Therefore, there is an urgent need to develop a microenvironment simulator capable of adjusting multiple environmental parameters such as radiation, temperature, and humidity to study changes in the microenvironment of citrus fruits and the accompanying alterations in their biological traits.

[0004] Furthermore, this type of growth box, capable of controlling specific environmental conditions, is not only suitable for research on sunburn in citrus fruits but can also be widely applied to quality improvement research on ordinary fruits. For example, by rationally adjusting light, temperature, and humidity conditions, the accumulation of sugars, vitamins, and other nutrients in the fruit can be significantly increased, thereby enhancing the commercial value of the fruit and providing technical support for increasing fruit yield and quality, thus possessing significant application value. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable environmental growth chamber for studying sunburn in citrus fruits, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable environment growth box for studying sunburn in citrus fruits, comprising an adjustable environment growth box bottom, a double-layer isolation structure, an inner wall heating element, and an adjustable environment growth box top. The adjustable environment growth box bottom includes connecting threads between the bottom and top, a bottom mounting seam, and a fruit stem fixing slot. The fruit stem fixing slot, through a ring clamp and its internal spring structure, automatically adjusts the state of the internal spring according to the thickness of the fruit stem, thereby automatically adjusting the clamping force of the ring clamp. At the same time, the surface is covered with a rubber protective layer to prevent damage to the fruit stem. The double-layer isolation structure includes a light-shielding layer, a connecting layer, and a heat-insulating layer. The adjustable environment growth box top includes a wiring hole, a light-shielding cover, an observation hole, an adjustable exhaust port, a bracket-type rotating structure, a connection port, a full-spectrum LED light ring, and a temperature and humidity sensor. The inner wall heating element is located on the inner wall of the adjustable environment growth box and can regulate the air temperature inside the growth box.

[0007] Preferably, the full-spectrum LED light ring is installed at the top of the box to simulate natural light, and the observation hole is equipped with a light-shielding cover to facilitate observation of the experimental progress and avoid interference from external light.

[0008] Preferably, the adjustable exhaust port adopts a grid design, which can reduce the entry of external light and control air circulation by adjusting the opening degree.

[0009] Preferably, the temperature and humidity sensor monitors the internal environmental data in real time and transmits the data to the temperature and humidity display.

[0010] Preferably, the bracket-type rotating structure is adjustable in angle and direction and is securely connected to the tripod via a connection port.

[0011] Preferably, the light-shielding layer is made of 2mm aluminum composite panel, the connecting layer is a 2mm polycarbonate connecting layer, and the thermal insulation interlayer is made of 2mm polyurethane foam, which can effectively isolate external light and heat transmission.

[0012] Preferably, the bottom and upper structures of the adjustable environment growth box are connected by threads to ensure a stable connection.

[0013] Preferably, the bottom of the adjustable environment growth box is equipped with a spring and sleeve structure to facilitate fruit installation.

[0014] Preferably, the sleeve structure inside the bottom of the adjustable environment growth chamber is made of flexible rubber, with a spring fixedly connected to one end. When an external force is applied, the inner and outer sleeves are misaligned under the action of the external force, and the end connected to the spring is compressed. When the external force disappears, the elasticity of the spring and the flexible material of the inner and outer sleeves cause the sleeve to automatically spring back to its initial state.

[0015] Preferably, the power connection wires for the adjustable exhaust port, the full-light source LED light ring, and the inner wall heating element are all led out from the cable hole and then connected to the power source.

[0016] Preferably, the adjustable environment growth chamber system includes a power supply, an adjustable growth chamber, a tripod, a temperature and humidity display, and a temperature, humidity, and radiation controller.

[0017] Preferably, the adjustable environment growth chamber monitors the internal environment data in real time through a temperature and humidity sensor and transmits the data to a temperature and humidity display. When the temperature and humidity inside the growth chamber are detected to be higher or lower than the set limits, the temperature, humidity and radiation controller feedback mechanism will automatically trigger the inner wall heating element and the adjustable exhaust vent to adjust the temperature and humidity inside the growth chamber.

[0018] Preferably, the tripod is connected to the connector to support height adjustment of the growth box.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. In this utility model, by combining components such as a full-spectrum LED light ring, an inner wall heating plate, an adjustable exhaust port, and a temperature and humidity sensor, the experimental environment can be comprehensively controlled and monitored in real time, thereby accurately simulating the natural conditions for the occurrence of citrus sunburn, establishing a functional relationship between citrus fruit sunburn and microenvironmental variables, and having important research value for revealing the pathogenesis mechanism of citrus sunburn and risk prediction and management.

[0021] 2. In addition to its application in the study of sunburn on citrus fruits, this utility model can also be applied to other fruit quality improvement studies. For example, by rationally adjusting radiation and temperature and humidity conditions, the effects of environmental changes on the accumulation of sugar and nutrients in fruits can be studied, thereby providing a simple and feasible solution for improving fruit quality under the environmental control of facility agriculture and creating high-quality fruits, thus broadening the application scope of the device.

[0022] 3. This utility model utilizes the combination of components such as a light-shielding layer and a light-shielding cover to effectively block the influence of external light and temperature and humidity changes on the microenvironment inside the chamber, thereby reducing the interference of the external environment on the test inside the chamber.

[0023] 4. The tripod in this invention connects to the connector to support the height adjustment of the growth box, which can be adjusted according to the different growth positions of the citrus fruit, greatly improving the flexibility and practicality of the experiment.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0031] like Figure 1 As shown, an adjustable environment growth box for studying sunburn in citrus fruits includes an adjustable environment growth box bottom 1, a double-layer isolation structure 2, an adjustable environment growth box top 3, and an inner wall heating element 9.

[0032] like Figure 1 and Figure 2 As shown, the top 3 of the adjustable environment growth chamber includes a cable hole 4, a bracket-type rotating structure 7, a connection port 8, a light-shielding cover 5, an adjustable exhaust port 6, a full-spectrum LED light ring 10, an observation hole 11, and a temperature and humidity sensor 13.

[0033] like Figure 1 and Figure 2 As shown, the adjustable environment growth chamber double-layer isolation structure 2 includes a light-shielding layer 2a, a connecting layer 2b, and a heat-insulating interlayer 2c.

[0034] like Figure 3 As shown, the bottom 1 of the adjustable environment growth box includes a bottom-upper structure connecting thread 15, a bottom mounting splice seam 14, and a fruit stem fixing slot 12.

[0035] like Figure 5As shown, the adjustable environment growth chamber system includes a power supply 20, a tripod 21, an adjustable environment growth chamber 19, a temperature and humidity display 22, and a temperature, humidity, and radiation controller 23.

[0036] Furthermore, such as Figure 2 As shown, the inner wall heating element 9 is installed in the middle of the inner wall of the adjustable growth chamber 19, and its purpose is to regulate the temperature inside the environmental growth chamber by heating the air.

[0037] Furthermore, the light-shielding layer 2a is made of 2mm aluminum-plastic composite board, the connecting layer 2b is made of 2mm polycarbonate, and the thermal insulation interlayer 2c is made of 2mm polyurethane foam. The light-shielding layer 2a is opaque to isolate the interference of external light during the experiment. The thermal insulation interlayer 2c between the light-shielding layer 2a and the connecting layer 2b is filled with thermal insulation material to reduce heat exchange between the inside and outside of the chamber.

[0038] Furthermore, the lower part of the connecting layer 2b is threaded, and it is connected to the bottom 1 of the adjustable environment growth box through the connecting thread 15.

[0039] Furthermore, the all-light source LED light ring 10 is installed at the top inside the adjustable environment growth box 19 to simulate natural light, and the light intensity is adjusted by the temperature, humidity and radiation controller 23.

[0040] Furthermore, the adjustable exhaust port 6 is installed on the top of the external side of the adjustable environment growth chamber 19, and the air intake and exhaust are controlled by the opening degree of the adjustable exhaust port 6 to adjust the air humidity.

[0041] Furthermore, the temperature and humidity sensor 13 is installed at the top inside the adjustable environment growth chamber 19. The temperature and humidity sensor 13 can continuously monitor the temperature and humidity changes inside the growth chamber. The data is transmitted to the temperature and humidity display 22 via wired transmission, which facilitates control and timely adjustment of the experimental environment and improves the stability of the experiment.

[0042] Furthermore, the observation hole 11 is located at the top center of the adjustable environment growth chamber 19, which allows for observation of changes in fruit characteristics during the experiment and facilitates adjustment of the experimental progress; when observation is needed, the light-blocking cover 5 is opened to observe the condition of citrus sunburn, and the light-blocking cover 5 is closed after the observation to reduce the influence of external light on the microenvironment inside the chamber.

[0043] Furthermore, the cable tray 4 is located at the top of the adjustable environment growth chamber 19, with the purpose of leading out the power connection cables of the inner wall heating element, the adjustable exhaust port 6 and the full-light source LED ring in the growth chamber from the cable tray 4, and then connecting them to the power supply 20.

[0044] Furthermore, the bracket-type rotating structure 7 is installed on the top of the adjustable environment growth box 19. The bracket-type rotating structure 7 can achieve free rotation within a certain range, which makes it convenient to adjust the position and angle of the growth box 19 according to the actual position of the fruit tree and fruit.

[0045] Furthermore, the connection port 8 of the bracket-type rotating structure 7 is designed flexibly and can be easily connected to the tripod through connecting rods, ropes and other fixing devices, ensuring that the growth box can be firmly installed on the tripod 21, while supporting quick disassembly and adjustment.

[0046] Furthermore, the fruit stem fixing slot 12 adopts a ring clamp, and the inside of the slot is equipped with a spring control structure, which can adjust the clamping force according to the thickness of the fruit stem. The inner layer of the clamp is added with a rubber pad to prevent damage to the fruit stem, thereby ensuring the normal growth of the fruit.

[0047] like Figure 4 The image shows a detailed view of the bottom 1 of an adjustable environmental growth box used for studying sunburn in citrus fruits. When installing the fruit, the spring 18 is in a compressed state, and the inner sleeve 16 is pulled out from the outer sleeve 17 under the action of external force, forming a space sufficient to place citrus fruits or other fruits and compressing the spring. After the fruit is installed, the spring 18 returns to its natural state under the action of elasticity, the inner sleeve 16 and the outer sleeve 17 are nested together, and the fruit stem fixing slot 12 fixes the fruit stem through the internal spring structure. The bottom 1 of the adjustable environmental growth box returns to its original shape.

[0048] Furthermore, both the inner sleeve 16 and the outer sleeve 17 are made of flexible rubber, with a spring 18 fixedly connected to one end. When an external force is applied, the inner sleeve 16 and the outer sleeve 17 can be offset from each other under the action of the external force; when the external force disappears, the elasticity of the spring and the flexible material of the inner sleeve 16 and the outer sleeve 17 cause the sleeves to automatically spring back to their initial state.

[0049] Furthermore, the upper structure of the adjustable environment growth chamber is connected to the bottom and upper structure by the lower thread of the connecting layer 2b and the connecting thread 15, ensuring a stable connection.

[0050] like Figure 5As shown, the workflow of the adjustable environment growth chamber system is as follows: Power supply 20 provides power to the inner wall heating element 9, full-spectrum LED light ring 10, and adjustable exhaust port 6 within the adjustable growth chamber 19. Temperature and humidity sensor 13 monitors the environmental data inside the chamber in real time and transmits the data to temperature and humidity display 22 and temperature, humidity, and radiation controller 23 via wired transmission. The temperature, humidity, and radiation controller consists of a temperature and humidity control module and a radiation control module. The temperature, humidity, and radiation controller 23 compares the monitored data with preset values. When the temperature and humidity exceed the set range, the temperature and humidity control module automatically triggers the inner wall heating element 9 (for heating) or the adjustable exhaust port 6 (for ventilation) to adjust the environment inside the chamber. The full-spectrum LED light ring 10 has its light intensity adjusted by the radiation control module of the temperature, humidity, and radiation controller 23 to simulate natural light. The entire system forms a closed-loop control to ensure stable environmental parameters.

[0051] Furthermore, the tripod 21 is connected to the growth box connection port 8, supporting the height and orientation adjustment of the adjustable environment growth box.

[0052] Furthermore, the fruit stalk fixing slot 12 secures the fruit stalk through a ring clamp and spring 18 structure. However, the overall weight of the growth box is mainly supported by the tripod 21, and the fruit stalk fixing slot 12 is only used to slightly fix the fruit position to avoid putting pressure on the fruit stalk. The inner sleeve 16 and the outer sleeve 17 are made of flexible rubber material, allowing slight movement of the fruit and preventing stress concentration. The elasticity of the spring 18 is optimized to provide only the necessary clamping force to ensure normal fruit growth.

[0053] Although embodiments of the present invention have been shown and described, those skilled in the art can make various changes, modifications, substitutions and alterations to the embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
