This can avoid the accumulation of dust and impurities, which will reduce the effective volume in the dust collector and affect the suction force and dust collection efficiency of the vacuum cleaner, thereby increasing the practicality of the device. Then, when cleaning the dust on the filter screen 7 inside the collection box 8, the collection box 8 can be released by toggling the limit component, and then the handle of the collection box 8 can be pulled to disengage it from the inside of the dust box 3. Then, when installing the collection box 8, the collection box 8 can be directly inserted into the inside of the dust box 3, and then it can be automatically limited and fixed by the limit component, thereby increasing the convenience of installation and disassembly of the device.

[0023] like Figures 1 - 4As shown, the cleaning assembly includes a second fixed plate 16, which is fixedly connected to the inside of the dust box 3, and a reciprocating screw rod 13 is rotatably connected between the top of the second fixed plate 16 and the bottom of the dust cover 2. The cleaning assembly also includes a first fixed plate 11, which is fixedly connected to the inside of the dust box 3, and a sliding rod 10 is fixedly connected between the top of the first fixed plate 11 and the bottom of the dust cover 2. A cleaning ring 12 is movably sleeved on the outer side of the sliding rod 10, and a threaded groove is provided on the other side of the cleaning ring 12 and is threadedly connected to the outer side of the reciprocating screw rod 13. A pinion 14 is fixedly connected to the outer side of the reciprocating screw rod 13, and a large gear 15 is rotatably connected to the inside of the dust box 3, and the outer side of the large gear 15 is meshed with the outer side of the small gear 14. A motor 4 is fixedly installed on the top of the dust box 3, and one end of the output shaft of the motor 4 is fixedly connected to one end of the rotating shaft of the large gear 15.

[0024] When cleaning, the output shaft of the starting motor 4 is rotated to drive the large gear 15 to rotate and the small gear 14 to rotate, and then the reciprocating screw 13 is driven to rotate and the cleaning ring 12 is driven to move on the outside of the slide rod 10. The cleaning ring 12 reciprocates on the outside of the inner wall of the dust collector body 1, so as to scrape and clean the dust and impurities adhering to the inner wall.

[0025] like Figures 1 - 4 As shown, the limit assembly includes a slider 22, which is slidably connected to the inside of the slide groove 17, and a spring 20 is fixedly connected between one side of the slider 22 and the inner wall of the slide groove 17. The limit assembly also includes a clamping block 21, which is slidably connected to the inside of the fixed block 6, and one end of the clamping block 21 is fixedly connected to one side of the slider 22. A clamping slot 9 is provided on the top of the collection box 8, and a limit groove 18 is penetrated through one side of the fixed block 6.

Then, when installing the collection box 8, one side of the collection box 8 is in contact with the inclined surface of the block 21, driving the block 21 to move and the slider 22 to move to compress the spring 20. Then, when one side of the groove 9 moves to the bottom of the block 21, the slider 22 is driven to move under the reaction of the spring 20 and the block 21 is automatically driven into the inside of the groove 9, thereby completing the fixation of the collection box 8.

[0027] The utility model provides an automatic dust cleaning mechanism inside a dust collection cylinder, and the specific working principle is as follows: first, when cleaning, the output shaft of the starting motor 4 is rotated to drive the large gear 15 to rotate and the small gear 14 to rotate, and then the reciprocating screw rod 13 is driven to rotate and the cleaning ring 12 is driven to move on the outside of the slide rod 10, and the cleaning ring 12 is reciprocated on the outside of the inner wall of the dust collection cylinder body 1, so as to scrape and clean the dust and impurities adhered to the inner wall thereof, and finally, when the fixation of the collection box 8 is released, the lever 19 is moved inside the limit groove 18 The sliding movement drives the slider 22 to slide inside the slide groove 17, and then drives the block 21 to disengage from the inside of the slot 9, and then releases the fixation of the collection box 8. Then, when installing the collection box 8, one side of the collection box 8 contacts the inclined surface of the block 21, driving the block 21 to move and the slider 22 to move to compress the spring 20. Then, when one side of the slot 9 moves to the bottom of the block 21, the reaction of the spring 20 drives the slider 22 to move and drives the block 21 to automatically enter the inside of the slot 9, thereby completing the fixation of the collection box 8.
