DETAILED DESCRIPTION

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The embodiment of the present invention provides a low-temperature cultivation device for a Paris polyphylla tropical rain forest, such as Figure 1-17 As shown, the Paris polyphylla tropical rain forest low-temperature cultivation device comprises: a box seat 1 and a heat-insulating outer shell 2, a heat-conducting inner shell 3, a front sealing plate 4 and a rear sealing plate 5 fixedly mounted on the top of the box seat 1, the heat-conducting inner shell 3 is located on the inner side of the heat-insulating outer shell 2, and the adjacent sides of the front sealing plate 4 and the rear sealing plate 5 are respectively fixedly connected to the front side and the rear side common to the heat-insulating outer shell 2 and the heat-conducting inner shell 3; the heat-insulating outer shell 2, the heat-conducting inner shell 3, the front sealing plate 4 and the rear sealing plate 5 and the top of the box seat 1 form an air guide cavity 6 located between the heat-insulating outer shell 2 and the heat-conducting inner shell 3, which is used for air circulation to absorb the heat of the heat-conducting inner shell 3 and its internal heat to achieve low-temperature cultivation; the heat-conducting A cultivation trough 7 is placed in the thermal inner shell 3 for laying soil to cultivate plants, and a drainage hole 8 is provided at the bottom of the cultivation trough 7 for draining excess water; a plurality of raised strips 9 located in the heat-conducting inner shell 3 are fixedly installed on the top of the box seat 1, which are used to support the bottom of the cultivation trough 7 after it is placed in, so that there is a gap between the bottom of the cultivation trough 7 and the top of the box seat 1, ensuring that excess water is discharged from the drainage hole 8; an air cooling chamber 10 and a liquid storage chamber 11 are provided in the box seat 1, and the air cooling chamber 10 cooperates with the air guide chamber 6 to realize air circulation, thereby dissipating heat to the heat-conducting inner shell 3 and its interior, and the liquid storage chamber 11 is used to store solution.

[0022] In this embodiment, first, a cultivation trough 7 is placed in the heat-conducting inner shell 3, and the bottom of the cultivation trough 7 is supported by a padding plate 9 to maintain a certain gap with the top of the box seat 1 so that excess water can be smoothly discharged through the drainage hole 8. Then, a proper amount of soil is laid in the cultivation trough 7, and Paris polyphylla is planted according to conventional plant cultivation methods. Ensure that the soil is moist and well-drained to provide a suitable growth environment. During temperature control and air circulation, the cold air in the air cooling chamber 10 is circulated through the air guide chamber 6 to absorb the heat of the heat-conducting inner shell 3 and its interior, thereby reducing the temperature of the cultivation environment.

[0023] This solution achieves control of the cultivation environment temperature through the ingenious design of the heat-insulating outer shell 2, the heat-conducting inner shell 3 and the air guide cavity 6. This design can not only effectively simulate the low temperature conditions required for the growth of Paris polyphylla, but also avoid the adverse effects on the plants caused by excessive temperature fluctuations.

[0024] The air cooling chamber 10 and the air guide chamber 6 are used in combination to ensure a continuous low temperature state of the cultivation environment. This efficient heat dissipation method not only improves the energy efficiency of the device, but also reduces energy consumption.

[0025] In addition to the basic temperature control function, the present invention also designs a liquid storage chamber 11 for storing and regulating the solution, which can not only provide the required moisture and nutrients for the plants, but also adjust the humidity and temperature of the cultivation environment according to actual needs, further enhancing the practicality and flexibility of the device.

[0026] In summary, the Paris polyphylla tropical rainforest low-temperature cultivation device described herein provides an effective solution for low-temperature cultivation of Paris polyphylla and other plants in warm areas such as tropical rainforests through its unique design and versatility.

[0027] In a further preferred embodiment of the present invention, the heat-conducting inner shell 3 is made of a heat-conducting material, the heat-insulating outer shell 2 is made of a heat-insulating material, and the thickness of the heat-insulating outer shell 2 is greater than the thickness of the heat-conducting inner shell 3 .

[0028] In this embodiment, the heat-conducting inner shell 3 is made of a material with excellent thermal conductivity, such as aluminum alloy or copper alloy, to ensure that the heat generated inside can be quickly and evenly transferred to the outside. At the same time, the heat-insulating outer shell 2 is made of a material with high thermal insulation performance, such as polyurethane foam or rock wool, and its thickness is designed to be greater than the thickness of the heat-conducting inner shell 3 to effectively isolate the influence of the external high temperature environment on the temperature in the cultivation space. Such a design allows the device to effectively reduce energy loss and improve energy efficiency while maintaining a low internal temperature.

[0029] When the device is running, the heat generated inside the heat-conducting inner shell 3 will be quickly transferred to the air guide cavity 6 through its good thermal conductivity, and heat exchange will be carried out with the cold air flowing in from the air cooling cavity 10. The heat-insulating outer shell 2 plays a key role in heat insulation, preventing external heat from entering the cultivation space through heat conduction or heat radiation, thereby ensuring a stable low-temperature state of the cultivation environment.

[0030] In a further preferred embodiment of the present invention, a liquid spraying mechanism is provided in the liquid storage chamber 11 and the heat-conducting inner shell 3 for spraying the solution on the cultivation trough 7. The liquid spraying mechanism includes a water pump 12, a drainage pipe 13, a liquid guide pipe 14 and a plurality of nozzles 15. The water pump 12 is provided in the liquid storage chamber 11 for absorbing the solution in the liquid storage chamber 11. The drainage pipe 13 is installed on the drainage end of the water pump 12, and the drainage end of the drainage pipe 13 extends to the side of the rear sealing plate 5 after the outside of the box seat 1. The liquid guide pipe 14 is provided in the heat-conducting inner shell 3 and is rotatably installed on the front sealing plate 4 and the rear sealing plate 5. The liquid inlet end of the liquid guide pipe 14 is sealed and rotatably connected to the drainage end of the drainage pipe 13 to realize the conduction of the solution. The plurality of nozzles 15 are all installed on the liquid guide pipe 14 and located in the heat-conducting inner shell 3 for spraying the required solution to the cultivation trough 7 below. The plurality of nozzles 15 are all provided with solenoid valves.

[0031] In this embodiment, the liquid storage chamber 11 stores the solution required for plant cultivation. When it is necessary to spray the solution on the plants in the cultivation trough 7, the water pump 12 is first started. The water pump 12 draws the solution from the liquid storage chamber 11 and transports the solution to the outside of the box seat 1 through the drainage pipe 13 until it reaches the side of the rear sealing plate 5. At this time, since the liquid guide tube 14 is connected to the discharge end of the drainage pipe 13 through a sealed rotation connection, the solution can smoothly enter the liquid guide tube 14. The liquid guide tube 14 passes through and is rotatably installed on the front sealing plate 4 and the rear sealing plate 5. This design allows the liquid guide tube 14 to rotate while maintaining a continuous supply of the solution. After the solution flows in the liquid guide tube 14, the required solution is sprayed onto the cultivation trough 7 below through a plurality of evenly distributed nozzles 15. Each nozzle 15 is provided with a solenoid valve, which can independently control the switch to achieve precise spraying.

[0032] The working principle of the liquid spraying mechanism is based on the suction effect of the water pump 12, and the solution in the liquid storage chamber 11 is transported to the nozzle 15 through the pipeline system for spraying. The sealed rotation connection between the discharge pipe 13 and the liquid guide pipe 14 ensures the continuity and stability of the solution during the transportation process, while allowing the cultivation device to maintain the spraying function during the rotation process. The solenoid valve on the nozzle 15 provides precise control of the spraying amount, which can be flexibly adjusted according to the needs of the plants.

[0033] In a further preferred embodiment of the present invention, a cooling air drainage mechanism is provided on the box seat 1, the heat-conducting inner shell 3, the front sealing plate 4, the rear sealing plate 5 and the liquid guide pipe 14, and the cooling air drainage mechanism includes an air drainage tube 16 and an air distribution shell 20. The air drainage tube 16 is fixedly installed on the rear sealing plate 5, and a turbofan 17 is rotatably installed in the air drainage tube 16 for draining air during rotation. An intake pipe 18 and an exhaust pipe 19 are installed on the air drainage tube 16, and the air inlet end of the intake pipe 18 is connected to the air cooling chamber 10, and the exhaust pipe 19 extends into the heat-conducting inner shell 3 after passing through the rear sealing plate 5. The exhaust pipe 19 is located on one side of the liquid guide pipe 14, and the air distribution shell 20 is fixedly sleeved on a section of the liquid guide pipe 14 located in the heat-conducting inner shell 3. An air distribution chamber 21 is provided between the air distribution shell 20 and the liquid guide pipe 14, so that the solution flowing in the liquid guide pipe 14 can further The air in the air cooling chamber 21 is cooled. The installation of the air distribution shell 20 avoids the nozzle 15. The air distribution shell 20 and the exhaust pipe 19 are connected by multiple telescopic tubes 22, so that the air distribution chamber 21 is connected with the inner cavity of the exhaust pipe 19. The air distribution shell 20 and the top inner wall of the heat-conducting inner shell 3 are connected by multiple hoses 23, so that the air distribution chamber 21 is connected with the air guide chamber 6. Two return air ports 24 are provided on the top inner wall of the air cooling chamber 10. The two return air ports 24 correspond to the bottom sides of the air guide chamber 6 respectively to realize the connection between the air guide chamber 6 and the air cooling chamber 10. A plurality of heat dissipating fins 25 are fixedly installed on the bottom inner wall of the air cooling chamber 10. The bottoms of the plurality of heat dissipating fins 25 extend into the solution in the liquid storage chamber 11 to realize heat conduction cooling. The top parts are all located in the air cooling chamber 10 for cooling the internal flowing air.

[0034] In this embodiment, when working, the turbofan 17 rotates in the air guide tube 16, generates suction, and draws air from the air cooling chamber 10 through the air intake pipe 18. The sucked air is discharged into the exhaust pipe 19, and then discharged into the air distribution shell 20 through the telescopic tube 22. Since the liquid guide tube 14 is fixedly mounted by the air distribution shell 20, in the air distribution chamber 21, the low-temperature solution flowing in the liquid guide tube 14 further cools the air. The cooled air then enters the air guide chamber 6 through the hose 23, and finally returns to the air cooling chamber 10 through the return port 24, forming a complete air cooling cycle. At the same time, the heat dissipation fin 25 located at the bottom of the air cooling chamber 10 is immersed in the solution of the liquid storage chamber 11, effectively absorbing and taking away the heat inside the device, further enhancing the cooling effect.

[0035] The working principle of the cooling air drainage mechanism mainly relies on the airflow generated by the rotation of the turbofan 17, the cooling effect of the air distribution cavity 21 formed by the liquid guide tube 14 and the air distribution shell 20, and the heat exchange function of the heat dissipation fin 25. When the turbofan 17 rotates, the hot air in the air cooling cavity 10 is sucked through the air intake pipe 18, and the hot air is discharged into the exhaust pipe 19 and then enters the air distribution shell 20. In the air distribution shell 20, the air exchanges heat with the low-temperature solution in the liquid guide tube 14, thereby reducing the temperature. Subsequently, the cooled air enters the air guide cavity 6 through the hose 23, and finally returns to the air cooling cavity 10 through the return air port 24. At the same time, the heat dissipation fin 25 effectively absorbs the heat inside the device by immersing it in the solution, and takes it away by contact with the air, thereby achieving an overall cooling effect.

[0036] In a further preferred embodiment of the present invention, the portions of the plurality of heat sink fins 25 located in the air cooling chamber 10 are provided with a plurality of gas guide holes 26 for allowing air to pass through and contact the heat sink fins 25 for cooling. The plurality of heat sink fins 25 are located between the two return air ports 24 and on both sides of the air inlet end of the intake pipe 18, so that the air discharged from the return air port 24 can be cooled by the heat sink fins 25 and then sucked into the intake pipe 18.

[0037] In this embodiment, a plurality of air guide holes 26 are provided in the portion of the heat dissipation fin 25 located in the air cooling chamber 10. These air guide holes 26 allow air to pass freely and fully contact the heat dissipation fin 25, thereby achieving effective heat exchange and cooling. In addition, the layout of the heat dissipation fin 25 ensures that they are located between the two air return ports 24 and on both sides of the air inlet end of the air intake pipe 18. This layout design means that the hot air discharged from the air return port 24 will first pass through the heat dissipation fin 25 for cooling before returning to the air intake pipe 18, thereby improving the efficiency of the entire cooling system.

[0038] The gas guide hole 26 on the heat dissipation fin 25 not only increases the contact area between the air and the heat dissipation fin 25, but also promotes the flow of air between the fins, thereby improving the heat exchange efficiency. When the hot air is discharged from the return air port 24 and enters the air cooling chamber 10, it will pass through the gas guide hole 26 of the heat dissipation fin 25 and exchange heat with the fin, thereby reducing the temperature. The cooled air is then sucked into the air intake pipe 18 and enters the cooling cycle again. Since the heat dissipation fin 25 is located on both sides of the air intake end of the air intake pipe 18, it can ensure that the inhaled air is fully cooled, thereby improving the stability and efficiency of the entire cooling system.

[0039] In a further preferred embodiment of the present invention, an operation opening is provided on the front sealing plate 4, and a cabinet door is hingedly mounted on the front sealing plate 4 for closing the operation opening.

[0040] In this embodiment, an operation port is provided on the front sealing plate 4, which provides a convenient passage for the user to operate and maintain the inside of the cultivation device. In order to maintain the sealing and safety of the cultivation device, a cabinet door is also hingedly installed on the front sealing plate 4, which can tightly close the operation port to prevent outside air and pollutants from entering the interior of the cultivation device.

[0041] In a further preferred embodiment of the present invention, the liquid inlet end of the liquid guiding tube 14 is connected to the liquid discharge end of the liquid discharge tube 13 by a rotary joint, and the other end of the liquid guiding tube 14 is a closed end.

[0042] In this embodiment, the liquid inlet end of the liquid guide tube 14 is connected to the liquid discharge end of the liquid discharge tube 13 by a rotary joint. This connection method not only ensures the stable connection between the liquid guide tube 14 and the liquid discharge tube 13, but also allows the two to rotate relative to each other within a certain range, so that the liquid can be sprayed in a swinging manner. At the same time, the other end of the liquid guide tube 14 is designed as a closed end to prevent the solution from leaking out during the flow process, thereby ensuring the safety and stability of the cultivation device.

[0043] In a further preferred embodiment of the present invention, the air drainage tube 16 and the liquid guiding tube 14 are staggered, and the telescopic tube 22 and the hose 23 are respectively located on two opposite sides of the air distribution shell 20 .

[0044] In this embodiment, the layout of the air guide tube 16 and the liquid guide tube 14 ensures that they are staggered to avoid mutual interference. At the same time, the telescopic tube 22 and the hose 23 are cleverly placed on opposite sides of the air distribution shell 20, respectively, to achieve reasonable air flow. The design of the telescopic tube 22 and the hose 23 also gives the liquid guide tube 14 the flexibility and adaptability required when rotating to meet the effect of swinging and spraying the solution. At the same time, the swinging solution can also improve the heat dissipation effect of the air in the air distribution cavity 21.

[0045] In a further preferred embodiment of the present invention, a heat conducting fin 27 is provided in the liquid guiding tube 14, and a plurality of heat dissipating fins 28 are fixedly mounted on the heat conducting fin 27. The plurality of heat dissipating fins 28 all penetrate the liquid guiding tube 14 and extend into the air distribution cavity 21. The plurality of heat dissipating fins 28 are all located on the flow route of air from the telescopic tube 22 to the hose 23, and are used for secondary cooling of the air. The plurality of heat dissipating fins 28 are all provided with a plurality of gas guide holes 29.

[0046] In this embodiment, a heat conducting fin 27 and a heat dissipating fin 28 are added inside the liquid conduit 14. Specifically, the heat conducting fin 27 is cleverly installed inside the liquid conduit 14, and a plurality of heat dissipating fins 28 are fixed thereon. These heat dissipating fins 28 not only penetrate the liquid conduit 14 and extend into the air distribution cavity 21, but are also located on the air flow route from the telescopic tube 22 to the hose 23, in order to achieve secondary cooling of the air flowing through. In addition, a plurality of gas guide holes 29 are carefully opened on the heat dissipating fins 28 to further optimize the air flow and heat dissipation effect.

[0047] The heat conducting fins 27 can efficiently absorb the heat of the solution in the liquid guiding tube 14, and transfer the heat to the air in the air distribution chamber 21 through the heat dissipating fins 28. Since the heat dissipating fins 28 are all located on the air flow route from the telescopic tube 22 to the hose 23, the air flow can be fully utilized to remove the heat, thereby achieving secondary cooling of the air. At the same time, the gas guide holes 29 on the heat dissipating fins 28 can guide the air to flow through the heat dissipating fins 28 more smoothly, increase the contact area and time between the air and the heat dissipating fins 28, and thus improve the heat dissipation efficiency. This design not only helps to maintain a suitable temperature inside the cultivation device, but also provides a more stable environmental condition for the growth of plants.

[0048] In a further preferred embodiment of the present invention, a temperature sensor 30 is provided in the heat-conducting inner shell 3, and liquid guide plates 31 are fixedly installed on the inner walls on both sides of the heat-conducting inner shell 3, and the two liquid guide plates 31 are both located above the cultivation trough 7, and are used to guide the solution on the inner wall of the heat-conducting inner shell 3 into the cultivation trough 7.

[0049] In this embodiment, a temperature sensor 30 and a liquid guide plate 31 are additionally provided inside the heat-conducting inner shell 3. Specifically, the temperature sensor 30 is cleverly installed inside the heat-conducting inner shell 3 to monitor the temperature inside the heat-conducting inner shell 3 in real time. At the same time, liquid guide plates 31 are fixedly installed on the inner walls on both sides of the heat-conducting inner shell 3. Both liquid guide plates 31 are located above the cultivation trough 7, and are intended to guide the residual solution on the inner wall of the heat-conducting inner shell 3 into the cultivation trough 7, so as to ensure full utilization of the solution and avoid waste.

[0050] The temperature sensor 30 can monitor the temperature inside the heat-conducting inner shell 3 in real time and transmit the temperature data to the control system (not shown in the figure). The control system can intelligently adjust the temperature inside the cultivation device according to the received temperature data to maintain a suitable plant growth environment. At the same time, when there is solution remaining on the inner wall of the heat-conducting inner shell 3, the liquid guide plate 31 can guide the solution to flow smoothly into the cultivation trough 7. Since the liquid guide plate 31 is located above the cultivation trough 7, it can ensure that the solution can accurately fall into the cultivation trough 7 to provide sufficient nutrition and water for the plants. This design not only improves the utilization rate of the solution, but also helps to maintain the stability of the solution concentration in the cultivation trough 7.

[0051] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments: In another embodiment of the present invention, a support plate 32 is fixedly installed on the outer side of the rear sealing plate 5, a drive motor 33 is fixedly installed on the support plate 32, a drive main shaft 34 is rotatably installed on the support plate 32, a synchronous wheel 35 is fixedly installed on the input end of the turbofan 17, the output shaft of the drive motor 33 and the drive main shaft 34, and the three synchronous wheels 35 are sleeved with the same synchronous belt 36.

[0052] In this embodiment, a support plate 32, a drive motor 33, a drive main shaft 34, a synchronous wheel 35, a synchronous belt 36 and other components are additionally provided on the outside of the rear sealing plate 5. Specifically, the support plate 32 is fixedly installed on the outside of the rear sealing plate 5 to support and fix the drive motor 33 and the drive main shaft 34. The synchronous wheel 35 is fixedly installed on the output shaft of the drive motor 33, the drive main shaft 34 and the input end of the turbofan 17, and the synchronous rotation between the three is achieved through the same synchronous belt 36.

[0053] When the drive motor 33 is started, its output shaft will drive the synchronous wheel 1 35 to rotate. Since the synchronous belt 1 36 tightly connects the three synchronous wheels 1 35 together, the drive main shaft 34 and the input end of the turbofan 17 will also rotate synchronously with the rotation of the synchronous wheel 1 35. This design not only realizes the direct drive of the turbofan 17 by the drive motor 33, but also ensures the synchronization and stability between the turbofan 17, the drive motor 33 and the drive main shaft 34 through the transmission effect of the synchronous belt 1 36. This synchronous rotation design helps to improve the working efficiency of the turbofan 17, thereby enhancing the air circulation and heat dissipation effect of the entire cultivation device.

[0054] In yet another embodiment of the present invention, a liquid infusion tube 37 is fixedly mounted on one side of the box seat 1 , and the liquid infusion tube 37 is communicated with the liquid storage chamber 11 .

[0055] In this embodiment, the box base 1 is additionally provided with a liquid replenishing tube 37. Specifically, the liquid replenishing tube 37 is fixedly installed on one side of the box base 1 and communicates with the liquid storage chamber 11. This design allows the user to conveniently replenish the solution in the liquid storage chamber 11, ensuring that the cultivation device continuously and stably provides the required nutrients and water for the plants.

[0056] When the solution in the liquid storage chamber 11 is reduced to a certain extent, the user can replenish new solution into the liquid storage chamber 11 through the liquid replenishing tube 37 .

[0057] In another embodiment of the present invention, an air supply pipe 38 is fixedly installed on one side of the box seat 1, and the air supply pipe 38 is connected to the air cooling chamber 10. An air pressure sensor is provided in the air cooling chamber 10. An electromagnetic valve is provided on the air supply pipe 38, and the electromagnetic valve is connected to the air pressure sensor.

[0058] In this embodiment, the air supply pipe 38 is fixedly installed on one side of the box base 1 and is connected to the air cooling chamber 10. An air pressure sensor is installed inside the air cooling chamber 10 to monitor the air pressure in the chamber in real time. At the same time, the air supply pipe 38 is equipped with a solenoid valve, which is connected to the air pressure sensor to form an intelligent air pressure regulation system.

[0059] When the air pressure in the air cooling chamber 10 is lower than the preset value, the air pressure sensor will send a signal to the solenoid valve. After receiving the signal, the solenoid valve will automatically open, allowing external air to enter the air cooling chamber 10 through the air supply pipe 38, thereby replenishing the air pressure. When the air pressure reaches or exceeds the preset value, the air pressure sensor will send a signal to the solenoid valve again, and the solenoid valve will automatically close to stop the air supply process. This intelligent regulation system ensures that the air pressure in the air cooling chamber 10 is always maintained within an appropriate range, providing stable environmental conditions for plant growth.

[0060] In another embodiment of the present invention, an arc-shaped driven tooth group 39 is fixedly installed on the outside of the air distribution shell 20, and a support strip plate 40 located above the driven tooth group 39 is fixedly installed between the front sealing plate 4 and the rear sealing plate 5. A mouth plate 41 is slidably sleeved on the support strip plate 40, and an active tooth group 42 meshing with the driven tooth group 39 is fixedly installed at the bottom of the mouth plate 41, so that the mouth plate 41 drives the air distribution shell 20 when it slides back and forth horizontally. The two sides of the die plate 41 are provided with a position positioning plate 43 fixedly mounted on the support strip plate 1 40, and a support strip plate 2 44 located on one side of the die plate 41 is fixedly installed between the front sealing plate 4 and the rear sealing plate 5. A power transmission short shaft 45 is rotatably installed on the support strip plate 2 44, and a connecting plate 46 is fixedly installed on the top of the power transmission short shaft 45. The connecting plate 46 is hingedly installed with the top of the die plate 41 by the same hinged rod 47, the hinge rod 47 is eccentrically installed on the connecting plate 46, so that when the connecting plate 46 rotates to drive the hinge rod 47, it pushes the mouth plate 41 to slide back and forth, and a support strip three 48 is provided on the side of the mouth plate 41 away from the support strip two 44, and the support strip three 48 is fixedly connected to the front sealing plate 4 and the rear sealing plate 5, and a return spring 49 is fixedly installed between the support strip three 48 and the mouth plate 41, and a power transmission long shaft 50 is rotatably installed on the front sealing plate 4 and the rear sealing plate 5, and the power transmission long shaft 50 is located below the support strip two 44, and the two are arranged in parallel, and the power transmission long shaft 50 and the power transmission short shaft 45 are both fixedly sleeved with a bevel gear 51, and the two bevel gears 51 are meshed, and the driving main shaft 34 and the power transmission long shaft 50 are both fixedly sleeved with a synchronous wheel two 52, and the two synchronous wheels two 52 are sleeved with the same synchronous belt two 53, so that the driving main shaft 34 drives the power transmission long shaft 50 to rotate.

[0061] In this embodiment, an arc-shaped driven tooth group 39 is fixedly installed on the outside of the air distribution shell 20, and a support strip plate 40 is installed between the front sealing plate 4 and the rear sealing plate 5. The die plate 41 is slidably mounted on the support strip plate 40, and a driving tooth group 42 meshing with the driven tooth group 39 is fixedly installed at its bottom. The air distribution shell 20 and the liquid guide tube 14 can be driven to deflect back and forth by the reciprocating lateral sliding of the die plate 41. In order to realize the reciprocating sliding of the die plate 41, a power transmission short shaft 45 is rotatably installed on the support strip plate 44, and is hinged to the top of the die plate 41 through a hinge rod 47. In addition, a transmission mechanism of a power transmission long shaft 50 and a bevel gear 51, as well as a synchronous transmission mechanism of a synchronous wheel 52 and a synchronous belt 53 are designed to realize the driving of the power transmission long shaft 50 by the driving main shaft 34.

[0062] When the driving main shaft 34 rotates, the power transmission long shaft 50 will also rotate through the transmission effect of the synchronous wheel 2 52 and the synchronous belt 2 53. The bevel gear 51 on the power transmission long shaft 50 meshes with the bevel gear 51 on the power transmission short shaft 45, so the power transmission short shaft 45 will also rotate. The rotating power transmission short shaft 45 drives the die plate 41 to slide back and forth on the support strip plate 1 40 through the transmission effect of the connecting plate 46 and the hinge rod 47. The active tooth group 42 at the bottom of the die plate 41 meshes with the driven tooth group 39, so the sliding of the die plate 41 will drive the air distribution shell 20 and the liquid guide tube 14 to deflect back and forth. At the same time, the reset spring 49 between the support strip plate 3 48 and the die plate 41 plays a role of reset and buffering.

[0063] The drive mechanism realizes the reciprocating deflection of the air distribution housing 20 and the liquid guide tube 14. This reciprocating deflection helps to optimize air cooling and solution distribution.

[0064] The transmission mechanism of the bevel gear 51, the synchronous wheel 52 and the synchronous belt 53 is adopted to ensure the efficient and stable transmission of power. This design not only improves the transmission efficiency, but also helps to reduce energy loss and transmission error.

[0065] In another embodiment of the present invention, an air guide shaft 54 ​​is rotatably installed in the air cooling chamber 10, and an air guide blade 55 located in the air cooling chamber 10 is fixedly sleeved on the air guide shaft 54. A synchronous wheel three 56 is fixedly sleeved on both the air guide shaft 54 ​​and the driving main shaft 34, and the two synchronous wheels three 56 are sleeved with the same synchronous belt three 57.

[0066] In this embodiment, an air guide shaft 54 ​​and its related components are added to the air cooling chamber 10. Specifically, the air guide shaft 54 ​​is rotatably installed in the air cooling chamber 10, and an air guide blade 55 is fixedly sleeved on the shaft. In order to drive the air guide shaft 54 ​​to rotate, a synchronous wheel 3 56 is fixedly sleeved on the air guide shaft 54 ​​and the driving main shaft 34, and the two are connected by the same synchronous belt 3 57. In this way, when the driving main shaft 34 rotates, the air guide shaft 54 ​​and the air guide blades 55 thereon can be driven to rotate together through the transmission effect of the synchronous belt 3 57 and the synchronous wheel 3 56.

[0067] The rotational power of the driving main shaft 34 is transmitted to the air guide shaft 54 ​​through the synchronous wheel 3 56 and the synchronous belt 3 57, so that it starts to rotate. As the air guide shaft 54 ​​rotates, the air guide blades 55 thereon also rotate, thereby generating a guide to the inside of the air cooling chamber 10.

[0068] In another embodiment of the present invention, a solution heat dissipation pipe 58 immersed in the solution is installed through the liquid storage chamber 11 for dissipating the solution heat through air flow, and both ends of the solution heat dissipation pipe 58 located outside the box seat 1 are open, a solution heat dissipation shaft 59 is rotatably installed in the solution heat dissipation pipe 58, and a heat dissipation blade 60 is fixedly installed on the solution heat dissipation shaft 59, a solution stirring shaft 61 is rotatably installed in the liquid storage chamber 11, and a stirring blade 62 is fixedly installed on the part of the solution stirring shaft 61 located in the liquid storage chamber 11, and a synchronous wheel four 63 is fixedly installed on the solution heat dissipation shaft 59, the solution stirring shaft 61 and the air drainage shaft 54, and the multiple synchronous wheels four 63 are sleeved with the same synchronous belt four 64.

[0069] In this embodiment, a solution heat dissipation pipe 58 immersed in the solution is installed through the liquid storage chamber 11, and both ends of the pipe are open outside the box seat 1. A solution heat dissipation shaft 59 is rotatably installed in the solution heat dissipation pipe 58, and a heat dissipation blade 60 is fixedly installed on the shaft. At the same time, a solution stirring shaft 61 is also rotatably installed in the liquid storage chamber 11, and a stirring blade 62 is fixedly installed on the shaft. In order to synchronously drive the solution heat dissipation shaft 59, the solution stirring shaft 61 and the air drainage shaft 54 ​​mentioned above, a synchronous wheel 9 63 is fixedly installed on these shafts, and they are connected by the same synchronous belt 9 64.

[0070] When the air drainage shaft 54 ​​(driven by the previous driving mechanism) rotates, the solution heat dissipation shaft 59 and the solution stirring shaft 61 will also rotate synchronously through the transmission effect of the synchronous wheel 4 63 and the synchronous belt 4 64. The rotation of the solution heat dissipation shaft 59 drives the heat dissipation blades 60 to rotate in the solution heat dissipation pipe 58, thereby generating airflow, which is exchanged with the outside air through the opening of the solution heat dissipation pipe 58 to achieve heat dissipation of the solution in the liquid storage chamber 11. At the same time, the rotation of the solution stirring shaft 61 drives the stirring blades 62 to rotate in the liquid storage chamber 11 to stir the solution to improve the uniformity and heat dissipation efficiency of the solution.

[0071] By adding the solution heat dissipation pipe 58 and the heat dissipation blade 60, effective heat dissipation of the solution in the liquid storage chamber 11 is achieved. This heat dissipation method not only improves the heat dissipation efficiency, but also helps to reduce the overall temperature of the device, providing more suitable environmental conditions for plant growth.

[0072] The design of the solution stirring shaft 61 and the stirring blades 62 enables the solution to be fully stirred in the liquid storage chamber 11, thereby improving the uniformity and fluidity of the solution, which helps the plant roots absorb and utilize nutrients and improves the cultivation efficiency.

[0073] The rotational power of the air drainage shaft 54 ​​is used to synchronously drive the solution heat dissipation shaft 59 and the solution stirring shaft 61, without the need for additional energy input. This design not only improves energy utilization efficiency, but also helps to reduce energy consumption and lower operating costs.

[0074] In summary, compared with the relevant technology, the present device realizes the control of the cultivation environment temperature through the design of the heat-insulating outer shell 2, the heat-conducting inner shell 3 and the air guide cavity 6. This design can not only effectively simulate the low temperature conditions required for the growth of Paris polyphylla, but also avoid the adverse effects on the plants caused by excessive temperature fluctuations.
