Difficulty, prolong the service life of the filter cartridge 24, reduce the frequency of replacing the filter cartridge 24, and greatly reduce the cost.

Referring to Figures 4 and 5, the wall of the filter cartridge 24 described in this embodiment is provided with a bead 6 for fixing the filter paper 26 . Specifically: one end of the bead 6 described in this embodiment is rotatably connected to the outer wall of the filter cartridge 24 , and the other end of the bead 6 is fastened to the outer wall of the filter cartridge 24 to fix the filter paper 26 to the outer wall of the filter cartridge 24 . When one end of the bead 6 fastened is opened to take out the filter paper 26, the bead 6 can be connected to the filter cartridge 24 through a rotatable end, and the bead 6 does not need to be separated from the filter cartridge 24, and the bead 6 is not easily lost. Moreover, the filter paper 26 described in this embodiment is closely attached to the outer wall of the filter cartridge 24 . The filter cartridge 24 can support the filter paper 26. The filter paper 26 is not easy to be deformed or even damaged due to the whirling of the sucked air in the cyclone space 25, and because the filter paper 26 is close to the outer wall of the filter cartridge 24, it can be more economical. The consumption of filter paper 26 reduces cost.

The bead in this embodiment is arranged axially along the outer wall of the filter cartridge. In other embodiments of the present invention, the bead can also be arranged in a ring around the circumference of the filter cartridge.

According to the idea of the embodiment of the utility model, those skilled in the art can also think of: the filter paper can be glued end to end without setting the bead, and put on the outside of the filter cylinder wall; or screws, etc. are fixed on the umbrella-shaped extensions at the upper and lower ends of the filter cartridge; in principle, as long as the filter paper can cover the outside of the area where the filter holes are provided on the filter cartridge, the fixing method of the filter paper is not limited to the above-mentioned embodiment. . In addition, the filter paper can be set in a single layer or in multiple layers. The multi-layer filter paper setting method can further improve the effect of blocking cotton, garbage or hair and other sundries; a roll of filter paper can also be set on the inner wall of the dust collection tube. The head end of the filter paper roll is pulled to the filter cylinder and fixed on the outside of the filter cylinder wall. When the filter paper needs to be replaced, just cut and discard the dirty filter paper, and fix the filter paper at the back section to continue to use until the whole roll of filter paper Replace with a new roll of filter paper after use. In this way, the replacement of filter paper can be facilitated. It is not necessary to prepare a single piece of filter paper every time the filter paper is replaced. In addition, breakpoints can be set on the filter paper at intervals, and each piece of filter paper needs to be cut and discarded. Easy to tear apart.

Referring to Fig. 6, an installation groove 7 is provided on the outer wall of the filter cartridge 24 described in the present embodiment, the bead 6 is installed in the installation groove 7, and the side wall of the installation groove 7 is provided with a card groove 71, and the bead 6 A protrusion 61 matched with the engaging groove 71 is provided on the side wall of one end of the fastening. The bead 6 is installed in the installation groove 7, so that it will not be higher than the surface of the outer wall of the filter cartridge 24, so the installation is more convenient and more beautiful. In addition, because the bead 6 is not higher than the surface of the outer wall of the filter cartridge 24, the cyclone space 25 between the filter cartridge 24 and the dust collection cylinder 23 will not be occupied, that is to say, the cyclone space 25 will not be reduced due to the bead 6 being set. It will not affect the swirling of the sucked air in the cyclone space 25, and can better ensure the separation effect of the dust collecting device 2 on the air with dust. To be specific: one end of the buckled bar 6 described in this embodiment is provided with a buckle groove 62 for pulling the bar 6 . Or there is a gap 72 between the buckled end of the bead 6 and the inner wall of the installation groove 7 , as shown in FIGS. 4 and 5 . It is more convenient to operate when it is necessary to open the bead 6. You can put your fingers in the button groove 62 to open the bead 6 outwards, or you can put your fingers on the gap 72 to open the bead 6. Of course, the user can also Use other tools such as a screwdriver instead of fingers to pull the bead 6 outward.

In other embodiments of the present utility model, the bead can also be directly installed on the outer wall of the filter cartridge.

The working principle of the utility model embodiment:

During actual use, the dust collecting device for a vacuum cleaner of this embodiment utilizes an electric blower to make the air sucked together by the suction piece and the dust swirl in the cyclone space 25 between the dust collection tube 23 and the filter tube 24, and the centrifugal force will The dust mixed in the air is separated. The airflow enters the filter cartridge 24 through the filter hole 241 on the wall of the filter cartridge 24, and is discharged from the air outlet 22 through the airflow channel, and the separated coarse dust is collected in the dust collecting box 3 below the dust collecting cartridge 23. The dust collecting device of the present embodiment is provided with filter paper 26 on the outside of the region where the filter hole 241 is provided on the side wall of the filter cylinder 24, so that the airflow can be filtered by the filter paper 26 before passing through the filter hole 241, because the filter hole of the filter paper 26 is quite small In this way, foreign matter such as cotton wool or hair and larger dust will be blocked outside the filter paper 26, unable to reach the filter hole 241 on the wall of the filter cartridge 24, some foreign matter is adhered to the filter paper 26, and the other part of foreign matter The dust is collected in the dust box 3, and the clean air can pass through the filter paper 26 and enter the filter cartridge 24 through the filter holes 241. This can effectively prevent the filter hole 241 from being entangled with foreign matter such as cotton wool or hair and cause blockage, and after being filtered by the filter paper 26, the airflow that can reach the filter hole 241 and enter the filter cartridge 24 is cleaner, greatly improving the filtering effect. And filter paper 26 adopts disposable filter paper usually, when accumulating foreign matter such as more dust or lint rubbish and hair, only need filter paper 26 is discarded together with rubbish sundry and gets final product, more convenient and simple, has reduced cleaning filter cartridge 24 difficulty, prolong the service life of the filter cartridge 24, reduce the frequency of replacing the filter cartridge 24, and greatly reduce the cost.
