The movable end of the spring 28 is connected to the squeezing ball 17. A heating component 7 is provided in the first mounting hole 6. A first groove 20 matched with the squeezing ball 17 is provided on the outer wall of the heating component 7. The cooperation between the first groove 20 and the squeezing ball 17 can realize the rapid loading and unloading of the heating component 7.

[0035] The cover plate 3 is covered on the upper top surface of the box body 1 , and a temperature control component is arranged on the cover plate 3 to cooperate with the heating component 7 for regulating the internal temperature of the box body 1 .

[0036] The device is provided by opening a first mounting hole 6 on the side wall of the box body 1, and opening a second mounting hole 27 in the first mounting hole 6, arranging a spring 28 in the second mounting hole 27, connecting a squeezing ball 17 to the movable end of the spring 28, and the squeezing ball 17 can be adapted to the first groove 20 on the heating component 7. When the heating component 7 is placed in the first mounting hole 6, the elastic force of the spring 28 squeezes the squeezing ball 17 into the first groove 20, thereby realizing the rapid installation of the heating component 7.

[0037] The cover plate 3 of the device is provided with a temperature control component that cooperates with the heating component 7. The temperature control component can detect whether the ambient temperature reaches the temperature required for sample growth. When the temperature control component detects that the ambient temperature is lower than the temperature required for sample growth, the temperature control component can control the heating component 7 to heat the inside of the box 1, and can quickly adjust the temperature inside the box 1.

[0038] like Figure 2 As shown, the heating assembly 7 includes a mounting frame 18 and a plurality of heating tubes 19 evenly arranged in the mounting frame 18. The heating tubes 19 are electrically connected to the temperature control assembly. After the heating assembly 7 is installed, the heating tubes 19 cooperate with the temperature control assembly on the cover plate 3 to achieve temperature regulation inside the box body 1. The heating tubes 19 in the mounting frame 18 are evenly distributed, so that the heating tubes 19 heat the inside of the box body 1 more evenly.

[0039] like Figure 3 As shown, the temperature control component includes a temperature controller 22 and a battery 23, both of which are arranged on the lower bottom wall of the cover plate 3. The temperature controller 22 is used to detect the ambient temperature and determine whether the temperature is suitable for sample growth. The battery 23 is used to provide power support for the device.

[0041] like Figure 1 , Figure 2 As shown, fixing blocks 9 are installed at the four corner edges of the bottom surface of the box body 1, and a drill rod 10 is installed at the lower end of the fixing block 9. The drill rod 10 can be inserted into the soil to seal the outside of the sample, and it is also beneficial for the box body 1 to be stably covered above the sample.

[0042] In some embodiments, a heat sink 11 is provided on the lower bottom surface of the box body 1, and ventilation holes 24 are opened in the horizontal direction of the heat sink 11, which is beneficial to ventilation and heat dissipation of the box body 1. A dustproof net 25 is fixedly installed on the ventilation hole 24. The dustproof net 25 can block dust from entering the box body 1 and reduce the impact of dust on the air inside the box body 1.

[0043] like Figure 1 , Figure 2 and Figure 4 As shown, the box body 1 is made of iron material, and a second groove 29 is provided on its bottom surface. A magnet block 26 matching the second groove 29 is provided on the heat sink 11. The magnet block 26 on the heat sink 11 is placed in the position of the second groove 29. Under the action of magnetic force, the box body 1 and the heat sink 11 can be quickly installed.

[0044] like Figure 1 , Figure 2 and Figure 6As shown, in some embodiments, a heat dissipation component is provided on the outer wall of the box body 1 , and the heat dissipation component is used for rapid heat dissipation inside the box body 1 .

[0045] like Figure 6 As shown, the heat dissipation assembly includes a fixed box 12 and a fan 30. The fixed box 12 is a hollow structure and is interconnected with the interior of the box body 1. The fan 30 is arranged in the fixed box 12. When the fan 30 is turned on, the fan 30 cooperates with the ventilation hole 24 to achieve ventilation and heat dissipation in the box body 1, which is more conducive to the growth and development of the sample.

[0046] Example 3

[0047] like Figure 2 As shown, a bearing plate 14 is arranged on the inner wall of the box body 1, a limiting hole 15 is opened on the bearing plate 14, and a limiting column 13 matching with the limiting hole 15 is arranged on the lower bottom surface of the cover plate 3. Through the matching of the limiting hole 15 and the limiting column 13, the cover plate 3 can be placed quickly and stably.

[0048] The inner wall of the box body 1 is also provided with evenly distributed water pipes 16 , and the humidity in the box body 1 can be ensured by adding a proper amount of water into the water pipes 16 .

[0049] An observation assembly is arranged on the cover plate 3, and the observation assembly includes an observation tube 4. The observation tube 4 is a hollow structure with two ends opened, one end of which is fixedly connected to the cover plate 3, and a glass plate 5 is fixedly installed on the other end. Through the glass plate 5, the growth of the sample can be better observed.

[0050] like Figure 3 As shown, a camera 21 is installed on the inner wall of the observation tube 4. When the camera 21 is turned on, the sample in the box 1 can be photographed and recorded, and the growth status of the sample can be recorded in a memory card provided in the camera 21.

[0051] When using the device of this embodiment, the cover plate 3 is placed on the top surface of the box 1, and the heating component 7 is placed in the first mounting hole 6. At this time, the elastic force of the spring 28 squeezes the squeezing ball 17 into the groove on the heating component 7, and the heating tube 19 and the thermostat 22 are electrically connected. Then the device is placed above the sample so that the sample is located in the box 1. The temperature is set by the thermostat 22. When the temperature in the box 1 does not reach the set temperature, the thermostat 22 controls the heating tube 19 to heat the inside of the box 1, so that the sample can grow at a specific temperature. The growth of the sample can be observed through the glass plate 5. The growth of the sample can be recorded in the memory card in the camera 21 by turning on the camera 21. The fan 30 is turned on to cooperate with the heat dissipation holes on the box 1 to achieve ventilation in the box 1, which is more conducive to the growth and development of the sample.
