Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the utility model provides a dust collecting component of robot sweeps floor, it includes collection dirt box body 1 and sets up at the inside filter assembly 2 of collection dirt box body 1, and the region between the inner wall of collection dirt box body 1 and the filter assembly 2 forms first collection dirt region 11. Wherein, the filter assembly 2 is constructed in a cylindrical structure or a conical structure, and the axial direction of the filter assembly 2 is the same as the length direction of the dust collecting box body.
Because the dust box among the prior art all sets up the sea handkerchief filtration at the air outlet department in its wind channel of injecing to increase the volume that the dust box holds the dust, however, so, the route of air current in the wind channel is very single, gets into from the air intake promptly, from the air outlet, makes the filter effect of dust not good. And the utility model discloses in, through set up the filter assembly 2 that extends along its length direction in collection dirt box body 1, though occupied partly collection dirt box body 1's volume, the air current can flow with spiral mode around filter assembly 2, therefore the route of air current is more diversified to make the dust more easily filtered, in order to improve the filter effect.
Specifically, one end of the filter assembly 2 is a closed end 21, and the other end is an air outlet end 22; the side wall of the dust collecting box body 1 is respectively provided with an air inlet 12 positioned at the side part of the filter component 2 and an air outlet 13 butted with an air outlet end 22 of the filter component 2. As shown in fig. 1, air enters from the air inlet 12, flows around the filter module 2 in a spiral manner, and then flows out from the air outlet 13.
Further, the closed end 21 abuts against an inner wall of the dust collection box body 1 disposed opposite to the air outlet 13. Specifically, as shown in fig. 2, the inner wall of the dust collection box body 1 is provided with a catch 14, and a closed end 21 is provided in the catch 14. The size of the clamping groove 14 is slightly smaller than that of the first end of the closed end 21, and when the closed end 21 is inserted into the clamping groove 14, the clamping groove 14 is elastically deformed so as to clamp the closed end 21; and the filter assembly 2 needs to be removed from the dust collection housing 1, the dust collection housing 1 is pulled to move the closed end 21 away from the catch 14. The mounting and dismounting of the closed end 21 is more convenient. Through the block connection between the filter assembly 2 and the dust collecting box body 1, the filter assembly 2 can be conveniently taken out of the dust collecting box body 1, so that dust in the dust collecting box body 1 can be poured conveniently.
As shown in fig. 2, the filter assembly 2 includes a filter element 23 and an element support 24 disposed inside the filter element 23, and the element support 24 extends in the axial direction of the filter element 23, thereby improving the strength of the filter element 23.
The surface of the filter element body 23 forms the air inlet part of the filter assembly 2. The surface of the filter element body 23 is provided with filter holes which constitute an air inlet portion of the filter assembly 2, in other words, air can enter the interior of the filter element body 23 from the surface thereof after entering the dust collection box body 1, thereby further filtering fine dust.
In the embodiment shown in fig. 2, the filter assembly 2 is constructed in a cone-shaped structure, and the cross-sectional area of the outlet end 22 is larger than that of the closed end 21. As shown in fig. 3, the position shown at a in fig. 3 is an area where the dust collection case 1 is first piled with the garbage, and thus the smaller end of the filter assembly 2 is provided in the area, which can reduce the internal space of the dust collection case 1 occupied by it.
