[0036] Principle and advantages of use: When in use, first move the box body 1 so that the installation tube 124 under the box body 1 is inserted into the upper side of the bracket matched therewith, and then rotate the anti-sliding block 122, and the anti-sliding block 122 causes the screw rod 121 to rotate and move, thereby moving the clamping pad 123, and the installation tube 124 can be fixed to the bracket under the action of the two clamping pads 123. When working, the air pump 51 generates negative pressure after working, and introduces the outside air from the air guide pipe 53 into the fixing seat, and then enters the air intake pipe 52 after being filtered by the filter element 4, and then enters the exhaust pipe 54 from the air intake pipe 52, and finally is discharged into the detection chamber 6 for detection, and when needed When the filter element 4 is to be disassembled and replaced, the operator moves the handle 86, and the handle 86 moves the blocking cover 81.
