Detailed Description

The present invention will be described in further detail with reference to the following embodiments and the accompanying drawings.

A dust collecting filter element structure of an air cleaner as shown in figure 1 comprises an air inlet nozzle 1, a filter paper 2, an ash collecting funnel 3 and an ash storage box 4 which are sequentially arranged from top to bottom in the vertical direction, wherein the filter paper 2 is in a folded corrugated structure and is curled into a cylinder shape. The lower end of the air intake nozzle 1 extends into the cylinder formed by the curling of the filter paper 2, so that the air passing through the air intake nozzle 1 must pass through the filter paper 2. The upper part of the ash collecting funnel 3 is completely buckled and covers the bottom of the filter paper 2, a funnel-shaped ash collecting opening which is opposite to the filter paper 2 is arranged on the ash collecting funnel 3, and the filtered sand and dust on the filter paper 2 can enter the ash storage box 4 through the ash collecting opening. The ash storage box 4 is connected with the bottom of the ash collecting funnel 3 through a screw, and a sealing strip is arranged between the ash collecting funnel 3 and the ash storage box 4 for sealing. The middle part of the ash storage box 4 is provided with an ash storage space which is sunken downwards, so that sand and dust entering the ash storage box 4 can be prevented from rotating to the outer surface of the filter element.

In one embodiment of the present invention, the filter paper 2 is curled into an elliptical cylinder, and the circumferential surface of the elliptical cylinder is covered with a metal tempering net 5.

In this embodiment, the air inlet direction of the air inlet nozzle 1 is horizontal, and the lower inner wall of the horizontal part of the air inlet is provided with a waterproof retaining wall 6, so that rainwater is prevented from horizontally flowing into the filter element, and meanwhile, the opening edge of the air inlet is an inclined opening edge with an upper part protruding and a lower part retracting, so that vertical rainfall is prevented from entering the filter element.

As shown in fig. 2, the air cleaner in the embodiment of the present invention includes the dust collecting filter element structure shown in fig. 1, and further includes an upper housing 7 and a lower housing 8, wherein the upper housing 7 and the lower housing 8 are relatively buckled and hermetically connected, and the air inlet nozzle 1 is hermetically connected to the upper housing 7; the filter paper 2 stretches into the lower shell 8, a gap for air circulation is reserved between the filter paper 2 and the inner wall of the lower shell 8, the ash collecting funnel 3 and the ash storage box 4 are both located in the lower shell 8, an air outlet is formed in one end of the lower shell 8, and an air pipe 9 is connected to the air outlet.
