[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] Reference Figure 1-Figure 11 A water bath temperature-controlled plant cultivation room comprises a cultivation cabinet 1 and a water bath container 2 arranged at the bottom of the cultivation cabinet 1. The interior of the cultivation cabinet 1 is provided with support plates 3 distributed in a linear array, and the upper surface of the support plate 3 is provided with water bath concave shells 4 distributed in a rectangular array. The inner surface of the water bath concave shell 4 is embedded with a plant container 5, and the interior of the plant container 5 is filled with nutrient solution. The interior of the cultivation cabinet 1 is respectively provided with a water bath circulation mechanism and a nutrient solution replenishing mechanism, and the interior of the cultivation cabinet 1 is provided with an LED growth lamp 8.

[0044] In order to ensure that the plants obtain sufficient carbon dioxide and oxygen, circulating air vents 9 are distributed in a rectangular array on the inner wall of the cultivation cabinet 1. Filters 10 are arranged on the surface of the circulating air vents 9. The arrangement of the circulating air vents 9 helps to form a uniform air flow in the cultivation cabinet 1, ensuring that all parts of the plants can obtain sufficient carbon dioxide and oxygen, ensuring the uniformity of the plant growth environment, and at the same time helping to dissipate heat and maintain a constant temperature. The filter 10 can filter out dust and other pollutants in the air, improve air quality, protect plants from harm, and reduce the occurrence of plant diseases.

[0045] In order to ensure the rapid circulation of fresh air, an air inlet 11 is opened on the back of the cultivation cabinet 1, and a fan 12 is fixedly installed on the outer surface of the air inlet 11. The air outlet end of the fan 12 is connected with the air inlet 11, and the air inlet 11 is connected with the circulating air outlet 9. The fan 12 draws external air into the cultivation cabinet 1 through the air inlet 11 to provide the necessary carbon dioxide for the plants and help regulate the air composition in the cultivation cabinet 1. Due to the use of the fan 12, air flow is mandatory, which more effectively controls the temperature, humidity and air composition in the cabinet, ensuring that the fresh air can be quickly and evenly distributed throughout the cultivation cabinet 1.

[0046] In order to increase the service life of the filter screen 10, the filter screen 10 is made of polyester fiber, which is corrosion-resistant and moisture-resistant.

[0047] Among them, in order to keep the nutrient solution in the plant container 5 warm, the water bath circulation mechanism includes a temperature sensor 6 fixedly installed on the surface of the water bath container 2, and the contact of the temperature sensor 6 extends into the water bath container 2. A temperature and humidity sensor 61 is fixedly installed on the upper surface of the cultivation cabinet 1, and a thermostat 62 is fixedly installed on the side surface of the cultivation cabinet 1. The water temperature in the water bath container 2 is monitored by the temperature sensor 6, and the temperature and humidity sensor 61 monitors the temperature and humidity in the cultivation cabinet 1. The temperature sensor 6 continuously monitors the actual temperature of the water bath and transmits the data to the thermostat 62. The thermostat 62 compares the actual temperature with the set temperature. If the actual temperature is higher than the set temperature, the heater 64 is turned off; if the actual temperature is lower than the set temperature, the heater 64 is turned on.

[0048] In order to protect the heater 64, a waterproof heat-conducting shell 63 is symmetrically installed inside the water bath container 2, and a heater 64 is installed inside the waterproof heat-conducting shell 63. The waterproof heat-conducting shell 63 is made of a thermally conductive silicone pad, which is a mixture of a silicone matrix and a thermally conductive filler, and can provide good thermal conductivity while maintaining a certain sealing and protective effect. The heater 64 is started so that the temperature generated by the heater 64 is transferred to the water in the water bath container 2.

[0049] In order to keep the nutrient solution in the plant container 5 warm, a suction pump 65 is installed on one side of the water bath container 2 in a linear array.

A first booster pump 67 is provided on the surface of the water pipe 66. The first booster pump 67 is installed on the inner wall of the cultivation cabinet 1. The water pipe 66 is fixedly connected to the bottom of multiple water bath concave shells 4 through multiple branch pipes. The bottoms of the multiple water bath concave shells 4 are fixedly connected to water outlet pipes 68 with valves. The three water outlet pipes 68 are fixedly connected to the bottom of the water bath concave shells 4. The free end is fixedly connected to the other side surface of the water bath container 2, and the suction pump 65 guides the heated water in the water bath container 2 into the water bath concave shell 4 through the water guide pipe 66 in sequence. The first booster pump 67 is convenient for guiding the water to the upper water bath concave shell 4, so that it flows in the water bath concave shell 4, which is convenient for heat conduction to the plant container 5, thereby keeping the nutrient solution in the plant container 5 warm, and then open the valve of the water outlet pipe 68, so that the water in the water bath concave shell 4 and the water in the water bath container 2 circulate, so as to avoid the water temperature in the water bath concave shell 4 from losing too fast and achieve a constant temperature effect.

[0050] In order to better keep warm, the water bath concave shell 4 is made of a vacuum insulation panel, and the plant container 5 is made of thermal insulation ceramics. The interior of the vacuum insulation panel is vacuum, which can effectively isolate heat transfer, so it has a good thermal insulation effect. At the same time, the surface of the vacuum insulation panel has good thermal conductivity to quickly transfer heat; the thermal insulation ceramics have a low thermal conductivity coefficient, which can effectively isolate heat and reduce heat loss.

[0051] By setting up a water bath circulation mechanism, it is not only convenient to heat the water in the water bath container 2, but also possible to introduce the heated water in the water bath container 2 into the water bath concave shell 4, so that the heated water wraps the plant container 5, thereby heating and insulating the nutrient solution in the plant container 5. The suction pump 65 and the first booster pump 67 facilitate the water in the water bath container 2 to be introduced from bottom to top into the plant containers 5 on the multiple support plates 3 in sequence, thereby achieving the effect of water bath insulation.

[0052] Among them, in order to replenish the nutrient solution in the plant container 5, the nutrient solution replenishing mechanism provided includes a nutrient solution container 7 fixedly installed inside the water bath container 2, a liquid outlet pipe 71 is fixedly connected to the surface of one side of the nutrient solution container 7, a water suction pump 72 is fixedly installed on the surface of the water bath container 2, one end of the liquid outlet pipe 71 extending out of the water bath container 2 is fixedly connected to the water suction end of the water suction pump 72, the water outlet end of the water suction pump 72 is fixedly connected to a liquid guide pipe 73, a second booster pump 74 is provided on the surface of the liquid guide pipe 73, the second booster pump 74 is installed on the surface of the cultivation cabinet 1, the liquid guide pipe 73 is fixedly connected to a shunt pipe 75 through a plurality of branch pipes, the water suction pump 72 discharges the nutrient solution in the nutrient solution container 7 through the liquid outlet pipe 71, and transports it to the shunt pipe 75 through the liquid guide pipe 73, and the second booster pump 74 facilitates the introduction of the nutrient solution into the shunt pipe 75 above.

[0053] In order to monitor the water levels in the water bath container 2 and the operating container, water level sensors 13 are installed inside the water bath container 2 and the nutrient solution container 7 .

[0054] In order to add the nutrient solution to the plant container 5, one of the shunt tubes 75 is fixedly installed on the inner top wall of the cultivation cabinet 1, and the other shunt tubes 75 are respectively fixedly installed on the bottom of multiple support plates 3. The liquid outlet of the shunt tube 75 is fixedly installed with a nozzle 76, and the multiple nozzles 76 are aimed at the plant container 5 one by one. The nutrient solution in the shunt tube 75 is sprayed out through the nozzle 76, so as to be sprayed into the plant container 5, thereby providing nutrition for the plants in the plant container 5.

[0055] By setting up a nutrient solution replenishing mechanism, it is convenient to keep the nutrient solution warm, and the nutrient solution in the plant container 5 can also be replenished to provide nutrition for the plants in the plant container 5. At the same time, it cooperates with the water bath circulation mechanism to maintain a certain temperature of the nutrient solution in the plant container 5, thereby achieving the effect of keeping the nutrient solution warm.

[0056] Working principle: When in use, place the plants to be cultivated into the plant container 5, and then close the door of the cultivation cabinet 1;

[0057] The heater 64 in the water bath container 2 is started, so that the heat generated by the heater 64 is transferred to the water body through the waterproof heat-conducting housing 63 to heat the water body. The temperature sensor 6 monitors the water temperature in the water bath container 2 in real time. The thermostat 62 receives the signal of the temperature sensor 6 and compares the monitored actual temperature with the set temperature target. When the actual temperature is higher than the set temperature, the heater 64 is turned off. When the actual temperature is lower than the set temperature, the heater 64 is turned on.

[0058] Then, the suction pump 65 and the first booster pump 67 are started, so that the heated water in the water bath container 2 is sequentially introduced into the water bath concave shell 4 on the support plate 3 through the water guide pipe 66, so that the water flows in the water bath concave shell 4, and then the valve on the water outlet pipe 68 is opened, so that the water in the water bath concave shell 4 and the water in the water bath container 2 are circulated to avoid the water temperature from being lost too quickly, so that the nutrient solution in the plant container 5 is kept at a constant temperature;

[0059] When the nutrient solution in the plant container 5 needs to be replenished, the water suction pump 72 and the second suction pump 65 are started, so that the nutrient solution in the nutrient solution container 7 is sequentially introduced into the diversion pipe 75 through the liquid guide pipe 73 and sprayed onto the plant container 5 from the nozzle 76.
