Due to the flow guiding effect of the flow guiding cylinder 80 on the air, part of particles in the air can fall to the bottom of the flow guiding cylinder 80 under the action of gravity. In this embodiment, the bottom of the guide cylinder 80 is provided with a through hole arranged towards the bottom of the dust cup body 11, and part of the particles can fall to the bottom of the dust cup body 11 through the through hole. Meanwhile, the air flow moves upwards towards the air outlet. Because the direction that sets up of air outlet channel in this embodiment is the direction of the inside orientation top air outlet of following cyclone cone 20, and filter 51 the corresponding inside that sets up in cyclone cone 20, the air filters the secondary filter effect of 51 through filtering once more at the in-process in dust removal chamber of discharging, will mix with tiny dust in the air to improve the separation effect of dust and gas separator to the air in this embodiment.
Fig. 8 is a schematic structural view of the cleaning frame in fig. 2. Fig. 9 is a schematic view of another perspective view of the cleaning frame of fig. 8. As shown in fig. 8 and 9, in some embodiments of the present invention, the dust-air separating apparatus further includes a cleaning frame 90, and the cleaning frame 90 is used for cleaning dust particles and hairs attached to the filter screen 21. The top of the cleaning frame 90 is a cylindrical structure covered on the outer wall of the filter screen. The cylindrical structure is also a hollow structure in order to discharge dust particles and hair cleaned from the filter screen 21. A cleaning member 92 such as a brush or a scraper is provided on an inner surface of the side wall plate 91 of the hollow structure, and a cutting member 93 is provided on an outer surface of the side wall plate 91. The cleaning member 92 in this embodiment may be a brush or a scraper, and the cutting member 93 may be a blade. When the cleaning frame 90 rotates, the cleaning members 92 of the inner surface of the sidewall plate 91 can clean the filter net 21 of dust particles, and the cutting members 93 of the outer surface of the sidewall plate 91 can cut the hair wound around the filter net 21, thereby separating the hair from the filter net 21. Be equipped with a plurality of arc through-holes 95 on clean frame 90's the mounting panel 94, dust particle and hair under the clearance on the filter screen 21 pass through arc through-hole 95 and drop to the bottom of dirt cup body 11 to need not to unpack apart dirt cup subassembly 10 and can clear up adnexed dust particle and hair on the filter screen 21 of cyclone cone 20, improve dirt gas separator's separation effect.
Further, in order to drive the cleaning frame 90 to rotate in the present embodiment, a mounting seat 96 is disposed at the bottom of the cleaning frame 90, and the mounting seat 96 is connected to the inner wall of the cleaning frame 90 through a supporting plate 97. The central point department of mount pad 96 is equipped with mounting hole 98, and mounting hole 98 and the coaxial setting of connecting hole 47 to rotation through actuating lever 71 can drive simultaneously that clean frame 90 and runing rest 40 rotate jointly, thereby clear up filter 51 and the filter screen 21 on the whirlwind awl 20 simultaneously.
In another aspect of the present invention, a vacuum cleaner having the dust-air separating apparatus of any one of the above embodiments is provided.
According to the dust collector disclosed by the invention, the dust removal assembly 30 is arranged in the air outlet channel of the dust-air separation device, and the dust removal assembly 30 is used for carrying out dust removal treatment on the filtering piece 51 in the dust cup assembly 10, so that dust on the filtering piece 51 is effectively cleaned under the condition that the dust cup assembly 10 is not required to be opened, the complexity of the dust removal process is reduced, the dust removal efficiency is improved, and the environmental pollution caused in the dust removal process can be effectively reduced.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
