[0030] Example 1 is illustrated in conjunction with Figures 1, 2, and 3:

[0031] A laboratory constant temperature and humidity air conditioning device includes: a bottom device 1, a top waste gas recovery cylinder 2, an air duct 3, a water inlet pipe 4, an air outlet switching cylinder 5, a motor drive assembly 6, and a connecting flange 7.

[0032] The duct 3 is installed on the top exhaust gas recovery cylinder 2 and is connected to the top exhaust gas recovery cylinder 2. The top exhaust gas recovery cylinder 2 can discharge or absorb gas through the duct 3.

[0033] The water inlet pipe 4 is rotatably mounted on the top exhaust gas recovery cylinder 2 and the air outlet switching cylinder 5 via bearings. The water inlet pipe 4 can rotate around the axis on the top exhaust gas recovery cylinder 2 and the air outlet switching cylinder 5.

[0034] The lower end of the water inlet pipe 4 passes through the top exhaust gas recovery cylinder 2 and connects to the bottom device 1. The exhaust gas switching drum 5 is rotatably installed inside the top exhaust gas recovery cylinder 2. The motor drive assembly 6 is fixedly installed inside the top exhaust gas recovery cylinder 2. The output end of the motor drive assembly 6 is connected to the exhaust gas switching drum 5. The lower side of the exhaust gas switching drum 5 is fixedly connected to the bottom device 1 through the connecting flange 7.

[0035] The motor drive assembly 6 can drive the air outlet switching drum 5 to rotate inside the top waste gas recovery drum 2. At the same time, when the air outlet switching drum 5 rotates, it can drive the bottom device 1 to rotate through the connecting flange 7.

[0036] Example 2 is illustrated in conjunction with Figures 4 and 5, based on Example 1:

[0037] The top exhaust gas recovery cylinder 2 has multiple sets of first exhaust gas recovery holes 21 evenly arranged on its side wall, and multiple sets of first ventilation holes 22 evenly arranged on its bottom. The first exhaust gas recovery holes 21 and the first ventilation holes 22 are used in conjunction with the air outlet switching cylinder 5.

[0038] The side wall of the air outlet switching rotary cylinder 5 is uniformly arranged with multiple sets of second exhaust gas recovery holes 51, and the bottom of the air outlet switching rotary cylinder 5 is uniformly arranged with multiple sets of second ventilation holes 52. The second exhaust gas recovery holes 51 are used in conjunction with the first exhaust gas recovery holes 21, and the second ventilation holes 52 are used in conjunction with the first ventilation holes 22. When the axes of the second exhaust gas recovery holes 51 and the second ventilation holes 52 coincide, the second ventilation holes 52 are blocked by the top exhaust gas recovery cylinder 2. When the axes of the second ventilation holes 52 and the first ventilation holes 22 coincide, the second exhaust gas recovery holes 51 are blocked by the top exhaust gas recovery cylinder 2.

[0039] When the second exhaust gas recovery hole 51 on the exhaust switching drum 5 is coaxial with the first exhaust gas recovery hole 21 on the top exhaust gas recovery drum 2, exhaust gas in the laboratory can be recovered. When the second vent hole 52 on the exhaust switching drum 5 is coaxial with the first vent hole 22 on the top exhaust gas recovery drum 2, gas can be delivered into the laboratory, thereby increasing the temperature and humidity in the laboratory.

[0040] Example 3 is illustrated in conjunction with Figures 4 and 5, based on Example 2:

[0041] The motor drive assembly 6 includes a servo motor 61, a drive gear 62, and a driven gear 63. The servo motor 61 is fixedly installed inside the top exhaust gas recovery cylinder 2. The output end of the servo motor 61 is fixedly connected to the drive gear 62. The drive gear 62 is meshed with the driven gear 63. The driven gear 63 is fixedly installed at the center of the air outlet switching cylinder 5. The center of the driven gear 63 is provided with a through hole for accommodating the water inlet pipe 4.

[0042] With this configuration, the servo motor 61 can drive the driven gear 63 to rotate through the drive gear 62, thereby driving the air outlet switching drum 5 to rotate.

[0043] Example 4 is described in conjunction with Figures 6, 7, and 8, based on Example 3:

[0044] The bottom of the device 1 is equipped with a temperature sensor 8 and a humidity sensor 9. The temperature sensor 8 and humidity sensor 9 are used to monitor the temperature and humidity in the laboratory.

[0045] The bottom device 1 has air outlets 11 on the left and right sides, and atomizing nozzles 12 on the front and rear sides. The atomizing nozzles 12 are connected to the heating pipe 14 through a water pump 13. The upper side of the heating pipe 14 is connected to the output end of the water pump 15 through a pipeline. The input end of the water pump 15 is connected to the output end of the water tank 16 located in the bottom device 1. The water pump 15 can transport water from the water tank 16 to the heating pipe 14.

[0046] A water tank 16 is mounted inside the bottom device 1 via a mounting plate 17, and the input end of the water tank 16 is connected to the lower end of the water inlet pipe 4. A water level gauge 161 is installed inside the water tank 16. The water level gauge 161 is used to detect the water level in the water tank 16. The pipeline is connected to the middle of the heating pipe 14, thereby improving heating efficiency.

[0047] The working principle of this utility model is as follows: When this device is in use, the second exhaust gas recovery hole 51 on the exhaust switching drum 5 is coaxial with the first exhaust gas recovery hole 21 on the top exhaust gas recovery drum 2, which can recover exhaust gas in the laboratory. When the second vent hole 52 on the exhaust switching drum 5 is coaxial with the first vent hole 22 on the top exhaust gas recovery drum 2, it can supply gas into the laboratory, thereby increasing the temperature and humidity in the laboratory. When heating and humidification are required in the laboratory, water in the water tank 16 is fed into the heating tube 14 by the water pump 15. Heating is achieved by drawing air from the air duct 3 into the bottom device 1 through the fan blades. After heating by the heating tube 14, hot air is blown out from the air outlet 11. The hot water in the heating tube 14 is sprayed to the outside through the water pump 13 and the atomizing nozzle 12. When it is necessary to control the temperature and humidity in the laboratory in all directions, the motor drive assembly 6 is started to drive the bottom device 1 to rotate and adjust the air outlet 11 to blow air in the direction of airflow. This utility model has a reasonable structure and is easy to use. It can both recover laboratory exhaust gas and control the temperature and humidity in all directions in the laboratory.
