[0037] The turntable 21 is used to drive the second vent hole 23 to rotate, the first vent hole 22 is used to connect the inside of the turntable 21 with the inside of the support box 11, the first rotating shaft 24 is used to drive the turntable 21 to rotate, the first knob 25 is used to drive the first rotating shaft 24 to rotate, the indicating arrow 26 is used to indicate the position of the second vent hole 23, the sensor group 27 is used to monitor the indoor environment of the laboratory, and the warning light 28 is used to warn the outside world;

[0038] The support assembly 1 also includes handles 12 fixedly connected to both sides of the upper end of the support box 11 and hollow circular grooves 13 opened around the upper end of the support box 11;

[0039] The handle 12 is used to drive the support box 11 to move, and the hollow circular groove 13 is used to correspond to the second vent hole 23;

[0040] The sensor group 27 includes a humidity sensor, a carbon monoxide sensor, a methane sensor and a formaldehyde sensor, and the sensor group 27 is respectively located above the hollow circular groove 13;

[0041] The sensor group 27 can monitor different harmful substances;

[0042] The warning light 28 is electrically connected to the sensor group 27 through a circuit, and the positions of the second vent holes 23 correspond to the positions of the hollow circular grooves 13 respectively;

[0043] When the sensor group 27 detects that the concentration of harmful substances exceeds the standard, the warning light 28 is controlled to start;

[0044] The first rotating shaft 24 passes through the center of the upper end of the supporting box 11, and the second vent hole 23 is located in the direction indicated by the indicating arrow 26;

[0045] When the first knob 25 drives the turntable 21 to rotate via the first rotating shaft 24, the indicating arrow 26 and the second vent hole 23 rotate on the same axis;

[0046] The interior of the turntable 21 is a hollow structure, and the first vent hole 22 is connected to the hollow circular groove 13 through the second vent hole 23;

[0047] The air inside the support box 11 can enter the inside of the turntable 21 through the first vent hole 22, and then be discharged into the inside of the hollow circular groove 13 through the second vent hole 23;

[0048] Working principle: When it is necessary to monitor the indoor environment of the laboratory, for example, when it is necessary to monitor the indoor air humidity content of the laboratory, determine the position of the second vent 23 according to the direction of the indicator arrow 26, turn the first knob 25, so that the first knob 25 drives the first shaft 24 to rotate, and the rotation of the first shaft 24 drives the turntable 21 to rotate. When the second vent 23 is located below the humidity sensor, stop turning the first knob 25. At this time, the air inside the support box 11 enters the turntable 21 through the first vent 22, and then enters the humidity sensor through the second vent 23 and the hollow circular groove 13. The humidity sensor measures the humidity. When the humidity is within the standard range, the warning light 28 keeps the green light on. When the humidity exceeds the standard range, the warning light 28 keeps the red light on. When it is necessary to monitor other harmful substances, just turn the first knob 25. The principle is the same as above.

[0053] The second knob 34 is located outside the support box 11, and a set of second rotating shafts 31 penetrate the support box 11 and extend outward;

[0054] When the second knob 34 is rotated, the second rotating shaft 31 is driven to rotate, and the second rotating shaft 31 drives the fan housing 32 to rotate;

[0055] Working principle: When the air quality inside the support box 11 needs to be monitored, the second knob 34 is turned to make the second knob 34 drive the second rotating shaft 31 to rotate, and the second rotating shaft 31 drives the fan housing 32 and the fan blades 33 to rotate. When the fan blades 33 are upward, the fan blades 33 are started to discharge the air at the lower end of the support box 11 upward into the turntable 21, so as to use the sensor for monitoring;

[0056] When the monitoring is completed, in order to avoid residual harmful substances in the turntable 21 during the next monitoring, the second rotation 34 is rotated in the reverse direction until the fan blades 33 are downward, so that the fan blades 33 discharge the air at the upper end of the support box 11 downward, thereby cleaning the air inside the turntable 21.
