[0036] The right side of the horizontal channel 29 is connected to the outside through the air inlet 20, and the right side of the middle space of the shell 1 is connected to the outside through the exhaust port 19.

The one-way valve in the air inlet 20 flows from right to left, the one-way valve in the exhaust port 19 flows from left to right, the one-way valve in the second one-way pipe 9 flows from the columnar groove 26 to the inside of the shell 1 in one direction, and the one-way valve in the vertical channel 30 flows from top to bottom. A second normally closed solenoid valve is installed in each of the air ports 19, a piston cylinder 17 is installed on the right side of the housing 1, a first piston block 37 that can slide left and right is arranged in the piston cylinder 17, the left side of the first piston block 37 is elastically connected to the left inner wall of the piston cylinder 17 through a spring 38, the rear side of the left space of the piston cylinder 17 is connected to the outside through the air hole 18, the right side of the first piston block 37 is fixedly connected to a connecting rod 16, the right side of the connecting rod 16 is fixedly connected to a vertical plate 13, and the left side of the vertical plate 13 is symmetrically fixedly connected to two sealing plugs 14;

[0037] Among them, two guide rods 15 are symmetrically fixedly connected to the right side of the shell 1, and the right sides of the two guide rods 15 pass through the vertical plate 13 together. An electromagnet 36 is embedded on the left inner wall of the piston cylinder 17. The first piston block 37 is magnetic. After the electromagnet 36 is energized, the adjacent surface of the first piston block 37 attracts each other with opposite charges. The electromagnet 36, the second normally closed solenoid valve and the motor 23 are in the same series circuit. The first mounting block 21 is installed on the right side of the shell 1, and the push switch 22 is installed on the right side of the first mounting block 21. The soil moisture sensor 32 cooperates with the water pump 24. When the soil moisture sensor 32 senses that the soil moisture is lower than the set humidity, it will control the water pump 24 to start. After reaching a certain humidity, Start and control the water pump 24 to shut down, the air temperature and humidity sensor 33 cooperates with the heating wire 35, the first normally closed solenoid valve and the semiconductor refrigeration component 10. The semiconductor refrigeration component 10 is composed of a semiconductor refrigeration plate and a heat dissipation fan. This is the prior art. When the air humidity is lower than the set minimum humidity, the first normally closed solenoid valve opens. When the air humidity is higher than the set maximum humidity, the first normally closed solenoid valve closes. Similarly, the heating wire 35 and the semiconductor refrigeration component 10 can be used to adjust the internal temperature and humidity. The push switch 22 is used to control the on and off of the soil moisture sensor 32 and the air temperature and humidity sensor 33 circuits. Only when the push switch 22 is triggered can the internal temperature and humidity be adjusted.

[0038] In the present invention, when it is used, the transparent sealed door 2 is opened, and then the soil is filled on the upper end of the mesh plate 27. The type of soil is one of brick red soil, red soil, red soil and yellow soil. Then, after the plants are planted in the soil, the transparent sealed door 2 is closed, and the circuit where the external program air motor 23 is located is energized for 3 minutes at intervals, and then closed. The adjustable fill light 34 can be adjusted to a suitable humidity according to the light requirement of the plant;

[0039] The motor 23 starts the electromagnet 36 and the two second normally open solenoid valves, and the electromagnet 36 is also energized. After the electromagnet 36 is energized, the first piston block 37 will slowly move to the left due to the small aperture of the air hole 18. In this process, the motor 23 drives the rotating disk 6 to rotate, thereby allowing the second piston block 45 to reciprocate back and forth through the connecting rod 7, which will generate a one-way gas flow between the outside, the air inlet 20, the first one-way tube 11, the columnar groove 26, the inside of the shell 1, the exhaust port 19 and the outside. The gas flow can discharge the gas inside the shell 1 to the outside and let in fresh air from the outside to achieve ventilation;

[0040] After a period of time, the first piston block 37 will move to the far left, at which time the two sealing plugs 14 will seal the air inlet 20 and the air outlet 19 respectively, and at the same time the vertical plate 13 will contact the push switch 22, so that the circuits of the soil moisture sensor 32 and the air temperature and humidity sensor 33 are turned on. When the soil moisture sensor 32 senses that the soil moisture is low, the water pump 24 will be started, so that the water body is pressed into the hollow bar 43 and discharged from multiple drainage ports 44 for watering. Since the motor 23 is started, the reciprocating screw rod 41 is in a rotating state, and the hollow bar 43 is driven to reciprocate left and right through the slider 42, so that the uniformity of the irrigation water body is improved;

[0041] Since the air inlet 20 and the exhaust port 19 are sealed at this time, as the second piston block 45 reciprocates back and forth, a circulating air flow will be generated in the shell 1, the first one-way tube 11, the columnar groove 26, and the shell 1. The air flow can make the temperature and humidity of the internal air more uniform, and the circulating gas will also pass through the soil to promote the growth of plant roots, and avoid the situation that the plant roots in the soil are lack of oxygen and rot. When the temperature of the circulating air is lower than the set minimum temperature, the heating wire 35 is started, and when the temperature of the circulating air is higher than the set maximum temperature, the semiconductor refrigeration element 10 is started, and when the humidity of the circulating air is lower than the set minimum humidity, the first normally closed solenoid valve is energized, and the connecting pipe 8 is turned on. When the gas passes through the second one-way tube 9, according to the Bernoulli principle, the water in the water tank 4 will be pressed into the second one-way tube 9 through the connecting pipe 8, and the water will contact with the high-speed flowing air and be quickly atomized, and then enter the shell 1 to achieve the purpose of humidification;

[0042] Finally, when the motor 23 is powered off, the regulating box will return to its initial state.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
