Referring to fig. 1, the inner hole of the dust falling hole 8 is aligned with the left filtering surface of the filtering net 62, so as to ensure that the filtered impurities fall into the dust storage box 7 through the dust falling hole 8.

Referring to fig. 1 and 3, the dust removing tube 2 is provided with an insertion slot 81, the insertion slot 81 is inserted into vertical plates at two ends of the dust storage box 7, the outer wall of one end of the dust removing tube 2 is provided with a fixed block 9, the fixed block 9 is provided with a through hole 91, the dust storage box 7 is provided with a locking groove 71, two sides of the dust storage box 7 are provided with locking pins 72, the number of the insertion slot 81, the fixed block 9 and the locking pins 72 is two and is arranged symmetrically with the vertical central axis of the dust storage box 7 as the center, the locking pins 72 penetrate through the through hole 91 to be inserted into the locking groove 71, a spring 73 is arranged between the fixed block 9 and the locking pins 72, when the dust storage box 7 is full of dust, the locking pins 72 at two sides can be pulled simultaneously and exit from the locking groove 71, at the moment, the spring 73 is stretched and deformed, the dust storage box 7 is moved downwards and exits from the insertion slot 81, the dust storage box 7 can be rapidly disassembled, loosen the locking pin 72, the spring 73 rebounds, and drives the locking pin 72 of both sides to move downwards and insert into the locking groove 71, so that the dust storage box 7 can be installed quickly, and the quick disassembly and assembly performance of the dust storage box 7 is improved.

The utility model discloses when concrete implementation: the power cord 21 is connected to an external 220V power supply, the dial button of the switch 22 is shifted to the right, the circuit is closed, the fan 5 is powered on and works, the fan blades can rotate at a high speed to form a strong suction force to the right, a strong air flow from the left to the right is formed in the dust removing pipe 2 and acts on each dust suction branch pipe 4 through the suction force of the air flow, each dust suction branch pipe 4 can comprehensively and quickly suck and remove the smoke dust and the suspended particle impurities in the roadway body 1, the sucked smoke dust and the suspended particle impurities flow through the dust guide pipe 41 to the right through the filter screen 62 and are filtered, the suspended particle impurities in the filtered smoke dust fall along the left end filter surface of the filter screen 62 and fall into the dust storage box 7 through the dust falling hole 8, the smoke dust with the filtered impurities continuously flows through the odor removing layer 63 to the right, the clear air is formed after the odor removing layer 63 is purified, the clear air continuously flows to the right and is discharged into the roadway body 1 through, improve the air quality to realize 1 inside air cycle in tunnel body, wholly improved comprehensive absorption rate and air purification nature to smoke and dust and suspended particle impurity.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
