Detailed Description

In order to make the invention more comprehensible, the following detailed description is given with reference to the accompanying drawings.

As shown in fig. 1 to 3, a cyclone device for cleaning the floor comprises a cyclone cover 51, a cyclone support 52, a plurality of cyclones 53, a dust box 54 and a dust box bottom cover 55. The cyclone cap 51 is provided with a communication opening 511. The cyclone cover 51 is provided on the cyclone support 52, and the cyclone support 52 has a discoid shape as a whole. The cyclone holder 52 is circumferentially provided with a plurality of conical inner cavities 521. Each conical inner cavity 521 is in the shape of a right-angled trapezoid in cross section. The sidewall of the cyclone holder 52 is provided with an upwardly opening arc-shaped opening 522 in an amount equal to the number of the conical inner chambers 521. The arcuate opening 522 communicates with the conical lumen 521. The upper part of the cyclone support 52 is provided with an air inlet 523 at the inner wall of each conical inner chamber 521. The center of the bottom of the cyclone support 52 is provided with a total air inlet 524 communicating with each air inlet 523. The dust box 54 is fitted over the cyclone holder 52. The dirt box 54 is cylindrical. The dust box 54 is provided with a dust box communication opening 541. The dust box 54 is provided with a circular through hole. The bottom of the dust box 54 is provided with a dust box ring 542, and a plurality of dust box partition plates 543 arranged circumferentially are arranged between the dust box ring 542 and the outer wall of the dust box 54. A dust box bottom cover 55 is provided at the bottom of the dust box 54. Each of the cyclones 53 is disposed on each of the conical cavities 521 and mates with the conical cavity 521. Each of the cyclones 53 is divided into a cylindrical portion and a conical portion. The cyclone sub-interface 533 is provided on the sidewall of the cylindrical section. The air outlet duct 531 is provided at the top center of the cylindrical portion. Can play better cyclone effect, dust collection efficiency is better. The bottom surface of the conical portion of each cyclone 53 is inclined, and the bottom surface of each cyclone 53 faces the central axis of the bottom cover 55 of the dust box. The centers of the top and bottom surfaces of the conical portion of each of the cyclones 53 are not in the same line. Can play better cyclone effect, prevent that the dust from flowing out. An air outlet pipe 531 is arranged at the top of each cyclone 53, and a spoiler 532 is arranged on each air outlet pipe 531.
