Principle of embodiment:
a blower in an air conditioner of an automobile is used as a power source of a dust collector, a second air inlet pipe 4 is connected to an air inlet pipe 2 in an internal circulation pipeline of the air conditioner, a valve is arranged on the air inlet pipe 2, when dust collection is needed, the valve is closed, a connecting sleeve 29 is inserted into a connector 7, and dust collection can be achieved by opening the blower, so that the dust collector is very convenient.
When the air conditioner is used at ordinary times, the valve is opened, air cannot enter the blower through the second air inlet pipe 4, and the air uniformly enters the blower through the air inlet pipe 2. The reason is that: at this time, the connecting sleeve 29 is not inserted into the sleeve 8, at this time, the abutting block 24 abuts against the end of the limit strip 22, the number of turns of the coil spring is large, the torsion is large, under the action of the torsion, the coil spring 10 applies the torsion to the gear, the gear applies the torsion to the transmission gear 14, the transmission gear 14 applies the torsion to the crown gear 13, and finally, the abutting block abuts against the end of the limit strip 22. Because the torsion of the coil spring 10 is large, the check plate 9 is tightly pressed against the end of the sleeve 8, when the air conditioner is in operation, negative pressure is formed in the second air inlet pipe 4 in time, but the pressure difference is enough to push the check plate 9 open, and air can not enter the blower through the second air inlet pipe 4.
When dust is required to be sucked, the third limiting block 36 on the connecting sleeve 29 is aligned with the limiting groove 21 and inserted into the sleeve 8, the connecting sleeve 29 pushes the connecting ring 20, the abutting block slides at the end of the limiting strip 22, the second guide cylinder 19 slides in the second guide groove 18, the second limiting block 30 slides in the third guide groove 25, when the abutting block slides out of the limiting strip 22, under the torsion of the coil spring 10, the connecting block 17 slides in the guide groove 16, the abutting block moves towards the limiting block 23, finally, the abutting block abuts against the limiting block 23, the second limiting block 30 is located in the second limiting groove 27, in the process, the crown gear 13 rotates, the transmission gear 14 rotates, the gear 12 rotates, the coil spring 10 twists, the number of turns of the coil spring 10 twists is reduced, and the torsion is reduced; that is, when it is desired to access the coupling sleeve 29, it is convenient to simply insert it into the sleeve 8, and the rest of the action is performed under the torsion of the coil spring 10. At the moment, during dust collection, negative pressure is formed in the second air inlet pipe 4, pressure difference is formed between two sides of the check plate 9, at the moment, due to the fact that torsion of the coil spring 10 is reduced, the check plate 9 is pushed away by air, the air carrying dust passes through the check plate 9, then the dust is filtered out through the filter screen 33, and after the air blower 1 is turned off, the check plate 9 abuts against the end portion of the sleeve 8 under the effect of the torsion of the coil spring, and the dust is prevented from returning to the interior of the vehicle through the check plate 9.
In the dust collection process, under the action of the torsion of the coil spring 10, the abutting block abuts against the limiting block 23 to prevent the coil spring 10 from losing the torsion, meanwhile, when the crown gear 13 rotates, the guide cylinder 15 is driven to rotate to drive the second guide cylinder 19 to rotate, the connecting ring 20 is driven to rotate to drive the connecting sleeve 29 to rotate, at the moment, the second limiting block 30 is located in the second limiting groove 27 to prevent the connecting sleeve 29 from being easily pulled out during dust collection, in addition, after the dust collection is finished, when the connecting sleeve 29 is pulled out, the connecting sleeve 29 needs to be rotated first, at the moment, the connecting sleeve 29 drives the connecting ring 20 to rotate to drive the second guide cylinder 19 to rotate to drive the guide cylinder 15 to rotate to drive the crown gear 13 to rotate, the transmission gear 14 is driven to rotate, the gear 12 is driven to rotate, and the coil spring 10 is driven to twist. Therefore, when the coupling sleeve 29 is rotated, it is necessary to overcome the torsion force of the coil spring, and the phase change explains the firmness of the coupling sleeve 29. When the second limiting block 30 slides to the end of the third guide groove 25, the connecting sleeve 29 is pulled outwards, the third limiting block 36 is made of a magnet, and the connecting ring 20 is made of a magnet, so that the third limiting block and the connecting ring 20 are adsorbed together, the connecting ring 20 moves along with the connecting sleeve 29 under the action of attraction, finally, the limiting protrusion 38 abuts against the limiting protrusion 37, the abutting block abuts against the end of the limiting strip 22, the second limiting block 30 is located in the third guide groove 25, at the moment, the connecting sleeve 29 is continuously pulled, the connecting ring 20 is separated from the connecting sleeve 29, at the moment, the torsion of the coil spring is increased, at the moment, when the air blower runs, air enters from the air inlet pipe 2 of the inner circulation pipe, and the connector plays a role of a valve.
Dust adsorbed on the filter screen will block the passage of air, thereby reducing the filtering speed. The spoiler is added, when the dust collector works, the spoiler abuts against the acute angle block and is in an inclined state, at the moment, airflow forms vortex in the filtering sleeve under the guiding action of the spoiler, the airflow pushes dust adsorbed on the filtering net to push the dust away, so that the air behind passes through, and the filtering speed of the clamping block is increased; the shape of spoiler and the cross section shape adaptation of filtering the telescopic, when the dust catcher is inoperative, under the effect of spring, the spoiler rotates and supports and leans on spacing post to the spoiler will filter the sleeve terminal surface and seal, when taking out filtering the telescopic time, the dust can not fly out from filtering the sleeve top, environmental protection more.
