[0029] An exhaust fan 10 is installed at the top of the outer shell 4, and a plurality of ventilation holes are provided at the top of the outer shell 4, so that the air in the livestock house can be drawn into the interior of the supporting inner cavity 3. A plurality of first ventilation holes 301 respectively connected to the interior of the first chamber 5 and the second chamber 6 are provided through the side wall of the supporting inner cavity 3, and an adjustment mechanism 9 for controlling the alternating opening and closing of the first ventilation holes 301 connected to the interior of the first chamber 5 and the second chamber 6 is provided on the inner wall of the supporting inner cavity 3. Referring to 5-6, the adjustment mechanism 9 includes first baffles 90 respectively abutting against the inner wall of the supporting inner cavity 3. The first baffle 901 and the second baffle 902 can be slidably connected with the inner side wall of the supporting inner cavity 3 through a slide rail. The first baffle 901 is arranged on the side wall close to the first chamber 5, and the second baffle 902 is arranged on the side wall close to the second chamber 6. The first baffle 901 and the second baffle 902 are respectively penetrated with a second ventilation hole 9011 and a third ventilation hole 9021 adapted to the first ventilation hole 301. Specifically, the first ventilation hole 301, the second ventilation hole 9011 and the third ventilation hole 9021 have the same size and are all strip-shaped through holes arranged at equal intervals from top to bottom. , the spacing between two adjacent adjustment through holes is greater than the width of the through holes, a gear 905 is installed on one side of the top of the base 1 through the rotation of the motor 906, and the first rack 903 and the second rack 904 are respectively provided on both sides of the radial direction of the gear 905 to slide up and down, the first rack 903 is fixedly connected to the first baffle 901, and the second rack 904 is fixedly connected to the second baffle 902, and the first rack 903 and the second rack 904 drive the first baffle 901 and the second baffle 902 to move up and down, so that the second ventilation hole 9011 and the third ventilation hole 9021 are connected to the first ventilation hole 3 01 overlap or separation, specifically, the motor 906 is installed on the top of the base 1 through the support plate, and its output end is fixed to the gear 905. When working, the motor 906 drives the gear 905 to rotate, and the gear 905 is meshed with the first rack 903 and the second rack 904, driving the first rack 903 and the second rack 904 to move in the opposite direction, and then driving the first baffle 901 and the second baffle 902 to move in the opposite direction, so as to adjust the opening and closing of the ventilation hole, and make the air entering the outer shell 4 be discharged after being heated or discharged after evaporation and heat absorption as needed.

[0030] Furthermore, a closed livestock house air environment control device also includes a plurality of exhaust fans installed on the wall of the livestock house, which can accelerate the air exchange between the livestock house and the outside.

[0031] Furthermore, a closed livestock and poultry house air environment control device also includes a controller, and the output ends of the temperature sensor 1501, the humidity sensor 1502 and the harmful gas detection sensor 1503 are electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input end of the exhaust fan 10, the exhaust fan, the electric heating tube 7, the water pump 12 and the motor 906, which can intelligently control the operation of each electrical component.

[0032] Working principle: When working, the temperature sensor 1501 detects the temperature inside the livestock house, the humidity sensor 1502 detects the internal humidity, and the harmful gas detection sensor 1503 detects the gas concentration of CO2, H2S or NH3;

[0033] When the temperature sensor 1501 detects that the temperature is low, the switches of the electric heating tube 7 and the exhaust fan 10 are turned on, and the exhaust fan 10 draws the cold air from the outside into the interior of the outer shell 4, and drives the gear 905 to rotate through the motor 906, and then drives the first rack 903 and the first baffle 901 to slide downward, so that the second ventilation hole 9011 coincides with the first ventilation hole 301 on the side wall of the first chamber 5. At this time, the third ventilation hole 9021 is separated from the first ventilation hole 301 on the side wall of the second chamber 6, so that the air entering the interior of the outer shell 4 can only be blown to the electric heating tube 7 through the second ventilation hole 9011. The electric heating tube 7 heats the cold air and then blows it out through the through hole in the outer shell 4. When the indoor temperature is high, the motor 9 06 drives the gear 905 to rotate in the opposite direction. At this time, the second rack 904 and the second baffle 902 descend, and the first baffle 901 and the first rack 903 rise, so that the third ventilation hole 9021 coincides with the first ventilation hole 301 on the side wall of the second chamber 6, and the second ventilation hole 9011 is separated from the first ventilation hole 301 on the side wall of the first chamber 5. The water pump 12 pumps the water inside the water tank 2 into the first water pipe 11, and then injects it into the evaporation heat absorption layer 8 through the water injection hole 1101. The exhaust fan 10 draws the outside air into the outer shell 4, supporting the formation of high pressure inside the inner cavity 3 and the outer shell 4. The air can only pass through the evaporation heat absorption layer 8 and then cool down to discharge the cold air, cool the livestock house, and ensure that the livestock and poultry are in a suitable temperature environment;

[0034] When the humidity sensor 1502 detects that the humidity in the livestock house exceeds the preset safety threshold, the system will automatically start the exhaust fan on the livestock house wall to exhaust the humid air inside the livestock house and maintain a suitable humidity environment; when the indoor humidity is low, the valve 1302 can be turned on, and the water pump 12 can draw the water in the water tank 2 into the ultrasonic atomizing nozzle 14 for atomization and then spray it out to increase the humidity in the livestock house to a suitable level;

[0035] When the harmful gas detection sensor 1503 detects that the concentration of any of CO2, H2S or NH3 exceeds the preset safety threshold, the exhaust fan will start. The exhaust fan will quickly exhaust the harmful gas to the outside, and the outdoor air will enter the livestock house through the doors and windows, effectively accelerating air exchange and quickly improving the air quality in the livestock house.

[0036] Embodiment 2, based on Embodiment 1, this embodiment is provided with a through hole connected to the inside of the water tank 2 on the base 1 below the evaporative heat absorption layer 8. Excess water infiltrating the evaporative heat absorption layer 8 will flow downward through the through hole back to the inside of the water tank 2 for continued recycling, which is more energy-saving and environmentally friendly.

[0037] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
