[0018] See also Figure 1 to Figure 4 In an embodiment of the utility model, a mobile air quality detection device includes a control cabinet 1, a fixed block 10 is fixedly installed on the back end of the control cabinet 1, a vertical rod 11 is fixedly connected to the inner wall of the fixed block 10, a support rod 2 for supporting the bottom end of the control cabinet 1 is fixedly connected to the bottom end of the vertical rod 11, a connecting ear 3 protruding outward is fixedly connected to the outer side of the support rod 2, a universal wheel 4 is fixedly installed at the bottom end of the connecting ear 3, a supporting mechanism penetrating to the bottom of the connecting ear 3 is installed at the bottom end of the connecting ear 3, a bottom plate 7 is connected to the bottom end of the supporting mechanism, the bottom plate 7 is an "I"-shaped structure, and an air intake mechanism is fixedly installed on the top of the horizontal plate portion at the center of the bottom plate 7; the air intake mechanism is used to press gas into the supporting mechanism, and the gas entering the supporting mechanism is used to lift and extend the supporting mechanism.

[0019] In this embodiment: first, the entire device is moved to a preset position by means of the universal wheel 4, and then the gas is pressed into the support mechanism by pressing the air intake mechanism, the air pressure in the support mechanism increases, causing the support mechanism to expand and extend, and the support mechanism can drive the support rod 2 to move synchronously through the connecting ear 3, the support rod 2 drives the vertical rod 11 to move upward, and the vertical rod 11 drives the control cabinet 1 to move upward as a whole through the fixed block 10, and the device can be raised to a preset height.

[0020] Please refer to Figure 3 and Figure 4 The air intake mechanism includes a connecting ring 13 fixedly connected to the top of the crossbar of the bottom plate 7, a bellows 16 fixedly connected to the top of the connecting ring 13, two limit rods 14 fixedly connected to the top of the bottom plate 7, a pressing plate 15 for pressing the bellows 16 slidably connected to the outer wall of the limit rod 14, a spring 17 connected to the top of the inner wall of the bellows 16 fixedly connected to the bottom of the inner wall of the connecting ring 13, four air pipes 12 connected to the outer wall of the connecting ring 13, the input end of the air pipe 12 is connected to the top of the sleeve 5, and the air pipe 12 is connected to the inner cavity of the sleeve 5; the air pipe 12 is a retractable corrugated hose structure. It should be pointed out that the connecting ring 13, the bellows 16, the pressing plate 15, the air pipe 12 and the sleeve 5 are sealed.

[0021] In this embodiment: the staff steps on the end of the pressing plate 15 with their feet, and the pressing plate 15 is forced to move downward, and the pressing plate 15 presses the top of the bellows 16. The gas enters the supporting mechanism through the four air pipes 12, so that the supporting mechanism is unfolded to realize the lifting function. In the process of the pressing plate 15 moving up and down, the pressing plate 15 moves up and down along the outer wall of the limiting rod 14, and the limiting rod 14 plays the role of limiting guide.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 The supporting mechanism includes a sleeve 5 fixedly connected to the top of the connecting ear 3, and the inner wall of the sleeve 5 is slidably connected with a telescopic rod 6 that passes through the bottom of the connecting ear 3, and the four telescopic rods 6 are fixedly connected to the top four corners of the bottom plate 7.

[0023] In this embodiment: after the gas enters the sleeve 5 through the air pipe 12, the air pressure in the inner cavity of the sleeve 5 increases, and the gas pressure group is used on the piston part at the top of the telescopic rod 6. At this time, the air pressure between the top of the piston part and the top of the inner cavity of the sleeve 5 increases, and the air pressure acts on the top of the piston part, and the piston part drives the telescopic rod 6 to move downward, and the telescopic rod 6 moving downward drives the bottom plate 7 to move downward until the bottom plate 7 can no longer move downward; when the bottom plate 7 can no longer move downward, the air pressure acts in the opposite direction on the top of the inner wall of the sleeve 5, and the sleeve 5 moves upward at this time. Since the air pipe 12 is a retractable corrugated hose structure, when the air pipe 12 moves upward in the sleeve 5, the air pipe 12 unfolds accordingly until the control cabinet 1 rises to a preset height.

[0024] An exhaust pipe and an air intake pipe protruding outward are integrally formed on the outer circumference of the connecting ring 13. The exhaust pipe and the air intake pipe are symmetrically arranged. A manual valve is installed on the exhaust pipe, and a one-way air intake valve is installed on the air intake pipe.

[0025] In this embodiment: during the process of the bellows 16 being subjected to force, the bellows 16 is compressed, and the air in the bellows 16 enters the sleeve 5 through the air pipe 12. After the force applied to the bellows 16 is removed, the spring 17 drives the bellows 16 to return to its original position. At this time, the outside air enters the bellows 16 through the air intake pipe and the one-way air intake valve.

[0026] When the device needs to be transferred, the manual valve on the exhaust pipe is opened. At this time, under the action of gravity of the control cabinet 1, the control cabinet 1 drives the sleeve 5 to move downward along the outer wall of the telescopic rod 6. At this time, the gas in the inner cavity of the sleeve 5 is discharged through the exhaust pipe until the control cabinet 1 is lowered to the lowest position. At this time, the bottom plate 7 is lifted and moved upward. The bottom plate 7 drives the telescopic rod 6 to move on the inner wall of the sleeve 5 until the bottom plate 7 is completely out of contact with the ground. Then the manual valve is closed. Under the action of negative pressure, the telescopic rod 6 and the bottom plate 7 cannot fall again under the action of gravity.

[0027] Please refer to Figure 1 and Figure 2 A connecting rod 8 is fixedly connected to the back end of the control cabinet 1 , and a detection module 9 is fixedly installed on the top of the connecting rod 8 .

[0028] In this embodiment, the wires of the detection module 9 are connected to the control cabinet 1 through the hollow cavity inside the connecting rod 8 .
