[0035] In this embodiment, by starting the telescopic driving member 1341, the telescopic driving member 1341 causes the first gear 1343 to rotate, thereby causing the rotating shaft 1347 to rotate, thereby causing the first connecting rod 1344 to move, thereby causing the sealing door 134 to move. The sealing door 134 can cover the connecting port 133 for sealing, thereby preventing rainwater from entering the purifier body 1 and preventing rainwater from damaging the purifier body 1.

[0036] The other end of the purifier body 1 is provided with a flip cover 11 through a hinge, and the side of the flip cover 11 is in contact with the purifier body 1, and the bottom of the flip cover 11 is provided with a plurality of groups of air outlets 111 for air outlet, and the shape of the air outlet 111 is conical. Since the air outlet 111 is conical, the upper end of the air outlet 111 is large and the lower end is small, so that the air can be sprayed out a farther distance and the air can be quickly diffused in the tunnel. A buckle assembly 15 for facilitating the opening of the flip cover 11 is also provided between the purifier body 1 and the flip cover 11.

[0037] A purification component 14 for purifying air is provided on one side of the purifier body 1 near the air intake component 13. The purification component 14 includes a limiting groove 147, which is evenly distributed in the purifier body 1. The purification component 14 also includes an activated carbon adsorption filter element 141, a non-woven filter element 142, a PP filter element 143 and a filter screen 144. The activated carbon adsorption filter element 141 is used to absorb the exhaust gas generated by the car, and the activated carbon adsorption filter element 141 is slidably installed in one of the limiting grooves 147. The activated carbon adsorption filter element 141 is mainly used to absorb the exhaust gas generated by the car, such as hydrocarbons, nitrogen oxides and other harmful gases emitted by fuel. This filter element can be slidably installed in one of the limiting grooves 147, which is convenient for users to replace or maintain.

In order to facilitate users to replace or maintain these filter elements, handles are installed on their outsides, and users can easily pull the filter element out of or push it into the limit groove 147 through the handles.

[0038] The purification component 14 also includes a first rotating drive member 148 and a lead screw 1482, and the lead screw 1482 is movably installed on both sides of the purifier body 1 through a bearing seat, the output end of the first rotating drive member 148 is fixedly connected to one end of the lead screw 1482, and the first rotating drive member 148 is fixed on the bearing seat, and a scraper 1481 is arranged on the lead screw 1482. When the first rotating drive member 148 is started, it drives the lead screw 1482 to rotate so that the scraper 1481 reciprocates up and down, and one side of the scraper 1481 contacts the surface of the filter 144. When the first rotating drive member 148 is started, it will drive the lead screw 1482 to rotate. When the lead screw 1482 rotates, the scraper 1481 will reciprocate up and down. With the movement of the scraper 1481, it can effectively scrape off the dust and impurities on the surface of the filter 144, so as to keep the filter 144 clean and the filtering efficiency. The purification component 14 also includes a dust collection box 145, which is fixed at the bottom of the purifier body 1, and a collection drawer 146 for collecting dust is slidably arranged in the dust collection box 145, and slide grooves 1461 are provided on both sides of the outside of the collection drawer 146, and a slide rail 1451 is fixed inside the dust collection box 145, and the slide rail 1451 is slidably matched with the slide groove 1461.

[0039] In this embodiment, by starting the first rotating drive member 148, the first rotating drive member 148 causes the lead screw 1482 to rotate, and the lead screw 1482 causes the scraper 1481 to move up and down, thereby scraping off the dust on the filter 144, and then the dust falls into the collection drawer 146. When the dust in the collection drawer 146 is full, the collection drawer 146 can be pulled out, and the dust in the collection drawer 146 can be processed centrally.

[0040] An air volume regulating component 17 for controlling the air volume is arranged near the purification component 14 inside the purifier body 1. The air volume regulating component 17 includes a support ring 171, and a gear ring 172 is rotatably arranged on one side of the support ring 171, and a plurality of groups of arc grooves 1721 are evenly arranged on the gear ring 172.

The air volume regulating component 17 also includes a second rotating driving member 174, and the output end of the second rotating driving member 174 is connected to a second gear 175, and the second gear 175 is engaged with the gear ring 172 to drive the gear ring 172 to rotate.

[0041] In this embodiment, when the air volume needs to be adjusted, the second rotating drive member 174 and the second gear 175 drive the gear ring 172 to rotate, and the rotation of the gear ring 172 drives the position of the arc groove 1721 to change. Since the limiting column 1731 slides in the arc groove 1721, the rotation of the gear ring 172 causes the position of the rotating block 173 to change. The position change of the rotating block 173 directly affects the size of the air circulation channel, thereby controlling the air volume.

[0042] An air supply assembly 16 for making air flow is provided on one side of the interior of the purifier body 1. The air supply assembly 16 can be detachably installed in the purifier body 1. The air supply assembly 16 includes a motor 162, and the motor 162 is fixed in the support tube 161. The output end of the motor 162 is connected to a fan blade 163, and when the motor 162 rotates, the fan blade 163 rotates at a high speed to make the air flow. A plurality of limiting holes 1611 are opened on the outside of the support tube 161. In this embodiment, by starting the motor 162, when the motor 162 rotates at a high speed, the motor 162 rotates the fan blades 163 to make the air flow, thereby sucking the air in the tunnel and the air outside the tunnel into the purifier body 1 for purification.

[0043] A plurality of threaded rods 18 are arranged outside the purifier body 1, one end of the threaded rod 18 extends into the purifier body 1 and is inserted into the limiting hole 1611 for fixing the support tube 161. A mounting member 12 is also fixed on the top of the purification component 14, and the mounting member 12 is used to fix the purification component 14 on the tunnel.

[0044] Working principle: When in use, the purifier body 1 is installed on the tunnel through the mounting member 12, the air inlet pipe 131 is inside the tunnel, the bellows 132 can be stretched to a suitable length, so that the bellows 132 passes through the air outlet of the tunnel, and then the connecting port 133 is installed on the air outlet of the tunnel. At this time, by starting the motor 162, when the motor 162 rotates at a high speed, the motor 162 rotates the fan blades 163 to make the air flow, so that the air in the tunnel and the air outside the tunnel are sucked into the purifier body 1 for purification, and the air passes through the filter 144 to filter dust, filter dust or other particulate matter, and is activated. The carbon adsorption filter element 141, the non-woven filter element 142 and the PP filter element 143 multi-stage adsorb other pollutants in the exhaust gas, so that the exhaust gas purification is more sufficient. The air outlet 111 is arranged at the bottom of the flip cover 11. Since the air outlet 111 is conical, the upper end of the air outlet 111 is large and the lower end is small, so that the air can be sprayed out farther and the air can be quickly diffused in the tunnel. When the dust on the filter screen 144 is accumulated, the first rotating driving member 148 is started, and the first rotating driving member 148 rotates the lead screw 1482, and the lead screw 1482 moves the scraper 1481 up and down to move the filter screen 144. The dust on the collecting drawer 144 is scraped off, and then the dust falls into the collecting drawer 146. When the collecting drawer 146 is full of dust, the collecting drawer 146 can be drawn out, and the dust in the collecting drawer 146 is processed centrally. When it rains, the telescopic driving member 1341 is started, and the telescopic driving member 1341 rotates the first gear 1343, and then the rotating shaft 1347 rotates, and then the first connecting rod 1344 moves, and then the sealing door 134 moves. The sealing door 134 can cover the connecting port 133 for sealing, so as to prevent rainwater from entering the purifier body 1 and damaging the purifier. The flip cover 11 can be opened by the action of the buckle assembly 15, and by rotating the threaded rod 18, one end of the threaded rod 18 is disengaged from the limiting hole 1611, so that the support cylinder 161 can be taken out for maintenance and replacement, and by starting the second rotating driving member 174, the second rotating driving member 174 rotates the second gear 175, and the second gear 175 rotates the gear ring 172. After the gear ring 172 rotates, the limiting column 1731 moves in the arc groove 1721, so that the rotating block 173 can move, so that the air intake volume can be adjusted through the action of each rotating block 173.
