[0012] This utility model provides a floor vacuuming device for home cleaning, which has the following beneficial effects:

[0013] (1) This utility model achieves the cleaning of dust adhering to the surface of the filter cylinder by the sliding of the brush on the filter cylinder through the installation ring, avoiding the blockage of the filter cylinder due to the large amount of dust, which affects the cleaning efficiency of the dust collection device on the ground. The rotation of the fan creates negative pressure in the dust collection box, and the air and the dust on the ground are sucked into the dust collection box through the suction port and connecting pipe. The dust filtered by the filter cylinder is left in the dust collection box, and the air overflows through the filter screen.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution as follows: Figures 1-5As shown in this embodiment, a floor vacuum cleaner for home renovation includes a trolley 1, a scraper 2 mounted on the trolley 1, a dust collection box 9 inside the trolley 1, an installation cover 10 above the dust collection box 9, a fixing frame 13 fixedly mounted inside the installation cover 10, a fan 14 rotatably mounted inside the fixing frame 13, a suction port 11 fixedly mounted below the trolley 1, an installation plate 18 threadedly connected inside the dust collection box 9, a filter cartridge 19 threadedly fitted below the installation plate 18, an installation ring 20 fitted outside the filter cartridge 19, a brush 21 fitted inside the installation ring 20, the brush 21 fitting against the outer side of the filter cartridge 19, a scraper 3 rotatably mounted on the trolley 1, the scraper 3 fitting against the surface of the scraper 2, and a conveyor belt 7 inside the trolley 1. The device is activated when the worker pushes the trolley 1 forward. The motor in the mounting cover 10 drives the drive wheel 16 to rotate, which, together with the belt 17 and the driven wheel 15, causes the fan 14 to rotate at high speed. This creates negative pressure in the dust collection box 9, drawing outside air in through the suction port 11 and connecting pipe 12. The air carries dust from the ground into the dust collection box 9, where it is filtered by the filter cartridge 19. The dust adheres to the outside of the filter cartridge 19 or remains in the dust collection box 9. The air then passes through the filter cartridge 19, enters the mounting cover 10, and overflows through the filter screen 27. The mounting cover 10 contains the filter screen 27. The driven wheel 15 is fitted onto the fan 14. The drive wheel 16 is rotatably mounted on the fixed frame 13, which is equipped with a belt 17. The belt 17 is connected to both the drive wheel 16 and the driven wheel 15. The trolley 1 contains the connecting pipe 12. The two ends of the connecting pipe 12 are fixedly connected to the suction port 11 and the dust collection box 9, respectively. The dust collection box 9 contains two sets of symmetrically distributed moving blocks 22. The mounting ring 20 is slidably connected to each of the two sets of moving blocks 22. The dust collection box 9 also contains two sets of symmetrically distributed lead screws 23. A fixed rod 24 is fixedly installed inside each moving block, and the mounting ring 20 is slidably sleeved with the fixed rod 24. A cam 26 is rotatably installed inside each moving block 22. After a period of use, the motor in the dust collection box 9 is started, driving the lead screw 23 to rotate. Under the limiting action of the dust collection box 9, the moving block 22 drives the mounting ring 20 and the brush 21 to slide on the surface of the filter cartridge 19, thus cleaning the dust adhering to the filter cartridge 19. The two ends of the lead screw 23 pass through the dust collection box 9 and rotate with it via bearings. The connection is as follows: the lead screw 23 passes through the corresponding moving block 22 and is threadedly connected to the moving block 22; two sets of symmetrically distributed springs 25 are sleeved on the fixed rod 24; the two ends of the springs 25 are fixedly connected to the mounting ring 20 and the moving block 22 respectively; the cam 26 is in contact with the mounting ring 20; during the sliding process of the brush 21 driven by the mounting ring 20, the motor in the moving block 22 is activated to drive the cam 26 to rotate; during the rotation of the cam 26, it intermittently pushes the mounting ring 20, which, together with the fixed rod 24 and the springs 25, causes the mounting ring 20 to drive the brush 21 to vibrate up and down on the moving block 22, shaking off the dust cleaned from the filter cartridge 19 and putting it into the dust collection box 9, thus preventing the dust from clogging the pores of the filter cartridge 19 and affecting the overall working efficiency of the vacuuming device.

[0023] like Figure 1 and Figure 2 As shown, two sets of symmetrically distributed mounting rods 4 are rotatably installed inside the trolley 1. Two sets of symmetrically distributed synchronous pulleys 5 are sleeved on the mounting rods 4. Two sets of symmetrically distributed synchronous belts 6 are provided inside the trolley 1. The synchronous belts 6 are respectively connected to the two sets of synchronous pulleys 5. The two sides of the conveyor belt 7 are respectively fixedly connected to the two sets of synchronous belts 6. The trolley 1 is provided with a collection box 8, which is slidably connected to the trolley 1. The two ends of the conveyor belt 7 are respectively set with the shovel plate 2 and the collection box 8. When the worker pushes the trolley 1, the shovel plate 2 is in front, and the front end of the shovel plate 2 is in contact with the ground. During the movement, the shovel plate 2 shovels solid impurities on the ground onto the shovel plate 2. The motor in the trolley 1 is started to drive the scraper 3 to rotate. During the counterclockwise rotation of the scraper 3, the solid impurities on the shovel plate 2 are intermittently pushed to the conveyor belt 7. The motor on the trolley 1 drives the mounting rods 4 to rotate, which, together with the synchronous belts 6 and synchronous pulleys 5, drives the conveyor belt 7 to transport the solid impurities on the conveyor belt 7 to the collection box 8.

[0024] This utility model provides a floor vacuum cleaner for home renovation and cleaning. Its working principle is as follows: When the worker pushes the cart 1 forward, the motor in the mounting cover 10 is activated, driving the drive wheel 16 to rotate. This, combined with the belt 17 and driven wheel 15, causes the fan 14 to rotate at high speed, creating negative pressure in the dust collection box 9. External air enters the dust collection box 9 through the suction port 11 and connecting pipe 12, carrying dust from the floor into the dust collection box 9. After being filtered by the filter cartridge 19, the dust adheres to the outside of the filter cartridge 19 or remains in the dust collection box 9. The air passes through the filter cartridge 19, enters the mounting cover 10, and overflows through the filter screen 27. After a period of use, the motor in the dust collection box 9 is activated, driving the lead screw 23 to rotate. Under the limiting action of the dust collection box 9, the moving block 22 drives the mounting ring 20 and brush 21 to slide on the surface of the filter cartridge 19, thus cleaning the dust adhering to the filter cartridge 19. The moving block 22 is activated during the sliding of the brush 21 by the mounting ring 20. The motor drives the cam 26 to rotate. During the rotation of the cam 26, it intermittently pushes the mounting ring 20. In conjunction with the fixing rod 24 and the spring 25, the mounting ring 20 drives the brush 21 to vibrate up and down on the moving block 22, shaking off the dust cleaned from the filter cartridge 19 and sending it into the dust collection box 9. This prevents the dust from clogging the pores of the filter cartridge 19 and affecting the overall working efficiency of the vacuuming device. As the operator pushes the cart 1, the shovel 2 is in front, with its front end in contact with the ground. During the movement, the shovel 2 shovels solid impurities from the ground onto the shovel 2. The motor in the cart 1 is started, which drives the scraper 3 to rotate. During the counterclockwise rotation of the scraper 3, it intermittently pushes the solid impurities on the shovel 2 toward the conveyor belt 7. The motor in the cart 1 drives the mounting rod 4 to rotate, which, in conjunction with the synchronous belt 6 and synchronous pulley 5, drives the conveyor belt 7 to transport the solid impurities on the conveyor belt 7 to the collection box 8, preventing the solid impurities from affecting the normal operation of the vacuuming device.
