It will be appreciated that the devices are multifunctional, regardless of their orientation in space.

The utility model discloses usual working face can be plane or curved surface, can incline, also can the level. For convenience of explanation, the embodiments of the present invention are placed on a horizontal plane and used on the horizontal plane, and thus "high and low" and "up and down" are defined.

Example one

The present embodiment provides a cyclone filter assembly, which comprises a dust cup, wherein a protective layer 2 is attached to the inner side of the side wall 1 of the dust cup, and the strength of the protective layer 2 is greater than that of the side wall 1 of the dust cup, as shown in fig. 1 to 6.

Illustratively, the material of the protective layer 2 is a mixture of PC +20 wt.% glass fiber, and the hardness can reach 91, and the material of the dust cup sidewall 1 is ABS (hardness is 78) or PC (hardness is 80).

Compared with the prior art, among the cyclone filter assembly that this embodiment provided, the inboard of collection dirt cup lateral wall 1 is attached to there is protective layer 2, and protective layer 2 can separation dust particle and the collision of collection dirt cup lateral wall 1, prevents that dust particle from leaving the mar at collection dirt cup lateral wall 1 to can protect the dust cup effectively, improve the aesthetic property and/or the dust observation definition of dust cup. Meanwhile, the strength of the protective layer 2 is greater than that of the side wall 1 of the dust collecting cup, so that the protective layer 2 with higher strength can increase the overall strength of the dust collecting cup, and the service life of the dust collecting cup is prolonged.

Exemplarily, the dust cup side wall 1 is circular, and in order to make the dust cup side wall 1 better fit with the protective layer 2, the radians of the dust cup side wall 1 and the protective layer 2 are equal, that is, the outer side of the protective layer 2 is tightly fit with the inner side of the dust cup side wall 1, so that the fitting property of the protective layer 2 and the dust cup side wall 1 is improved, and the protective layer 2 is prevented from falling off in the collision process of dust particles.

In order to guide the dust particles and reduce the impact of the dust particles on the protective layer 2, the inner side of the protective layer 2 is also arc-shaped, and it should be noted that the inner side of the protective layer 2 may be arc-shaped or not, and in practical application, the radian of the inner side of the protective layer 2 may be adjusted according to practical situations.

In order to further improve the protection of the protective layer 2 on the side wall 1 of the dust collecting cup, the average thickness of the protective layer 2 is greater than or equal to the thickness of the side wall 1 of the dust collecting cup, and the thickness of the maximum thickness part of the protective layer 2 is 1.5-2.5 times of the thickness of the side wall 1 of the dust collecting cup. Like this, the whole thickness of protective layer 2 can be guaranteed to the average thickness that protective layer 2 is more than or equal to the thickness of collection dirt cup lateral wall 1, and simultaneously, the thickness of the maximum thickness department of protective layer 2 is 1.5 ~ 2.5 times of collection dirt cup lateral wall 1 thickness, and to the region that dust particle striking frequency is higher, the impact force is great, further increases protective layer 2's thickness, makes it can play the effect of protection collection dirt cup lateral wall 1 effectively.

In order to reduce the influence of the marks on the overall aesthetic property of the cyclone filter assembly, a decorative layer (e.g., a stripe pattern, a diamond pattern, etc.) or a logo layer (e.g., a pick-and-place instruction of the dust cup, etc.) may be printed between the side wall 1 of the dust cup and the protective layer 2, considering that the cyclone filter assembly inevitably leaves some marks on the protective layer 2 after a long time of use. When the dust particles filtered out from the dust outlet 6 contact with the protective layer 2 to cause the scratch for protectiveness, the scratch can be shielded through the decorative layer or the identification layer, so that the whole effect of the dust collecting cup body can not be influenced. In addition, the printing of the decorative layer or the mark layer between the side wall 1 of the dust cup and the protective layer 2 does not affect the smoothness of the outer surface of the side wall 1 of the dust cup.

It will be appreciated that the cyclone filter assembly described above also includes a filter located within the dirt cup in order to effect cyclonic separation of the dirt and dust by the cyclone filter assembly. Particularly, this filter includes the outer cover body 3, wind-guiding spiral plate 4 and filters screen panel 5, filters screen panel 5 and locates the inside of outer cover body 3, and wind-guiding spiral plate 4 is located between filtering screen panel 5 and the outer cover body 3, and centers on in the outside of filtering screen panel 5, and outer cover body 3, wind-guiding spiral plate 4 and filtering screen panel 5 form the helical passage jointly, and the lateral wall of the outer cover body 3 is equipped with dust outlet 6. The dust-containing fluid enters from a dust inlet of the spiral channel and centrifugally rotates through the spiral channel to form cyclone, dust with larger particles is separated under the centrifugal action, is discharged from a dust outlet 6 and enters a dust storage area 7 of the dust cup, and the dust-containing fluid subjected to primary filtration is guided to the filter screen 5 for further filtration.

Regarding the position of the protective layer 2, the protective layer 2 partially or completely covers the inner side of the dust cup sidewall 1, and more specifically, when the protective layer 2 partially covers the inner side of the dust cup sidewall 1, the position of the protective layer 2 corresponds to the opening area of the dust outlet 6. This is because the position corresponding to the opening area of the dust outlet 6 is the position where dust particles strike the sidewall 1 of the dust cup most severely, and the protective layer 2 is provided in this area, which not only can effectively protect the sidewall 1 of the dust cup, but also can reduce the material used for the protective layer 2, thereby reducing the cost of the cyclone filter assembly. It should be noted that, for example, the protective layer 2 is circular or circular arc-shaped, the outer cover 3 is circular, and the dust outlet 6 is circular arc-shaped, and "correspond" means that the symmetry axes of the protective layer 2 and the dust outlet 6 are coincident with each other along the radial direction of the protective layer 2 (or the dust outlet 6).

It will be appreciated that the area of the protective layer 2 is larger than the area of the open area of the dust outlet 6, so that the dust particles can all come into contact with the protective layer 2.

In order to prevent the dust particles in the dust storage area 7 of the dust cup from being guided to the dust outlet 6 of the filter again and causing backflow, the filter further comprises a dust baffle plate 8, the dust baffle plate 8 is positioned at the bottom of the outer cover body 3, and the dust baffle plate 8 is arranged along the central axis direction of the outer cover body 3, so that cyclone can be prevented from being generated in the dust collection area, and the dust in the dust storage area 7 can be effectively prevented from being guided to the dust outlet 6 along with the cyclone.

In order to realize the connection between the dust collecting cup and the main body of the dust collecting equipment, the cyclone filter assembly also comprises a front end part 9 arranged at the front end of the dust collecting cup, a fluid pipeline 10 is arranged on the front end part 9, a fluid outlet of the fluid pipeline 10 is communicated with a fluid inlet of the spiral channel, and dust-containing fluid enters the spiral channel through the fluid pipeline 10.
