In order to achieve the above object, according to the present invention, there is provided a cyclone dusting device of a cleaner comprising a cylinder having an upstream air inlet, a filter screen disposed in the cylinder and an inner cyclone cylinder disposed in the filter screen. Between the cylinder and the filter screen, an upstream Staubabscheidekammer and a first dust chamber below the upstream Staubabscheidekammer are arranged. In the internal cyclone cylinder, a downstream Staubabscheidekammer is formed. The upper side wall of the internal cyclone cylinder is equipped with a downstream air inlet and the lower side wall of the internal cyclone cylinder is equipped with a dust outlet, which is connected to a second dust chamber.

Preferably, the upper side wall of the inner cyclone cylinder is provided with a plurality of inclined inlets forming the downstream air inlet, and the inclined inlets are evenly distributed along the circumference of the inner cyclone cylinder.

Preferably, the bottom of the cylinder is provided with a bottom cap, a button switch is disposed between the cylinder and the bottom cap, and when the button switch is pressed, the cylinder and the bottom cap are separated from each other.

Preferably, the top of the cylinder is provided with an upper cover and a filter plate is disposed between a conical grid and the upper cover.

Preferably, the lower portion of the inner cyclone cylinder has the shape of a cone.

Preferably, the conical grid is also arranged in the internal cyclone cylinder.

By using the above structure in the present utility model invention, the cyclone cylinder has the advantages of a compact internal structure and a high centrifugal dedusting effect, while the multi-cyclone filtration achieves within a limited space, reduces the pressure loss of the entire cleaner, improves the permanent vacuuming ability and avoids secondary pollution.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In order that those skilled in the art may better understand the advantages and features of the present invention and clearly grasp the scope of the invention, the preferred embodiment of the present invention will become more readily apparent from the following 1 - 6 described in more detail.

As 1 - 6 show, a multi-cyclone dusting device of a cleaner according to the present utility model invention comprises a cylinder 1 with an upstream air inlet 11 , a coaxial in the cylinder 1 arranged filter screen 4 , a coaxial filter in the filter 4 arranged inside cyclone cylinders 5 , a coaxial in the inside cyclone cylinder 5 arranged conical grid 6 , one at the top of the cylinder 1 arranged upper cover 2 and one at the bottom of the cylinder 1 arranged bottom cap 3 , Between the cylinder 1 and the filter screen 4 are an upstream Staubabscheidekammer 7 and a first dust chamber 13 below the upstream Staubabscheidekammer 7 arranged. The filter screen 4 is with a plurality of stitches 41 fitted. The filter screen 4 and the internal cyclone cylinder 5 form an intermediate spiral air channel 8th , Between the inner cyclone cylinder 5 and the conical grid 6 is a downstream Staubabscheidekammer 9 educated. The upper side wall of the internal cyclone cylinder 5 is with a downstream air intake 51 equipped and the lower section of the internal cyclone cylinder 5 has the shape of a cone. The lower side wall of the internal cyclone cylinder 5 is with a dust outlet 52 equipped and the dust outlet 52 is in a second dust chamber 14 , When the air flows with fine dust to the downstream Zyklonstaubabscheidekammer, the fine dust falls spirally on the bottom of the inner cyclone cylinder 5 , and then the fine dust through the dust outlet without resistance 52 ejected from the downstream Staubabscheidekammer and enters the second dust chamber 14 one.

As 5 and 6 show is the upper portion of the internal cyclone cylinder 5 equipped with a plurality of inclined inlets that the downstream air inlet 51 form, and are the inclined inlets along the circumference of the inner cyclone cylinder 5 equally distributed. If dust enters the inner cyclone cylinder, it thus retains its spiral shape, so that there is no additional impact and the air pressure in the internal cyclone cylinder is maintained.

The bottom of the cylinder 1 is with a bottom cap 3 provided. Between the cylinder 1 and the bottom cap 3 is a button switch 10 arranged, and when the button switch 10 is pressed, the cylinder 1 and the bottom cap 3 separated from each other. Thus, after the dust is collected, the user only needs the button switch 10 to push the dust out of the first dust chamber 13 and the second dust chamber 14 to remove.

Between the conical grid 6 and the top cover 2 is a filter plate 12 arranged. After the air, which was separated twice, from the downstream Staubabscheidekammer 9 ascends, the air becomes cleaner after passing through the filter plate 12 was filtered.

In the multi-cyclic dusting apparatus, among the elements for improving the sealing effect of the entire structure, a plurality of sealing rings are provided.

As 3 - 6 show the dusty air spiral over the upstream air inlet 11 in the upstream Staubabscheidekammer 7 one. The air with large particles of dust moves along the cylinder 1 adjacent inner wall down to form the outer spiral air. The dust in the outer spiral air approaches under the centrifugal force of the inner wall of the cylinder 1 , After the dust on the inner wall surface of the cylinder 1 has collected, it falls under the influence of the outer spiral air in the first dust chamber 13 and remains on the bottom cap after being separated 3 be liable. The air with a small amount of fine dust passes over the mesh 41 in the air duct 8th and then spirals up over the downstream air inlet 51 in the downstream Staubabscheidekammer 9 and completes the upper cyclone movement. The dust is in the first dust chamber 13 under the centrifugal force via the lower dust outlet 52 deposited. The clean air, which has been separated twice, rises from the central grid of the conical grid 6 upwards and is discharged after passing through the filter plate 12 was filtered.

By using the above structure in the present utility model, the cyclone cylinder has the advantages of a compact internal structure and a high centrifugal dedusting effect, while the multi-cyclone filtration achieves within a limited space, reduces the pressure loss of the entire cleaner, improves the permanent vacuuming ability and avoids secondary pollution.

The foregoing description of the embodiment is intended to illustrate the technology and characteristics of the present utility model invention. This should give the person skilled the opportunity to understand this utility model invention and put into practice. It is not intended to limit the scope of the invention. Any changes and modifications made without departing from the invention in a broad sense are deemed to be within the scope of the invention.
