As shown in fig. 14 to 18, the filter element 36 is rotatably disposed in the filter chamber 31, the filter element 36 has a negative pressure space therein, the blower 32 forms a negative pressure in the negative pressure space, and at least a part of the filter element 36 is formed as an annular brush 361 disposed around the negative pressure space.

Specifically, a rotary filter element 36 is arranged inside the filter cavity 31, a negative pressure space formed by the fan 32 is arranged in the filter element 36, the negative pressure formed by the fan 32 is used for sucking dust into the filter cavity 31 through the first dust suction duct 11 and the second dust suction duct 14, and at least one part of the filter element 36 is formed into an annular brush 361 arranged around the negative pressure space.

Alternatively, the filter element 36 may be cylindrical, and the effective filtering area may be increased by adding pleats.

Further, as shown in fig. 14 to 18, the filter module 3 may further include: dust vibrating motor 38, drive gear 381, drive chain 39.

Meanwhile, the dust vibrating motor 38 drives the filter element 36 to rotate at a constant speed, and the poking piece 37 is matched with the filter element 36 to flap the filter element 36, so that dust can be filtered continuously and effectively, and the service life of the filter element 36 is prolonged. The filter element 36 and the paddle 37 are engaged in the same zigzag manner, and the strength of the paddle 37 and the contact area between the filter element 36 and the paddle 37 are increased by using 90-degree polyurethane having high hardness.

In summary, the dust raised by the cleaning disk 41 of the cleaning robot 100 according to the embodiment of the present invention enters through the relatively closed trumpet-shaped inlet (composed of the rubber cover and the curved sheet metal cover) by the forward speed of the cleaning robot 100 and the negative pressure formed by the fan 32, and then enters into the dust collecting channel through the second sub-pipe 352; on the other hand, the rolling brush 5 is connected with the dust collecting container 2, the rubber sheet of the surrounding edge is in soft contact with the ground by adopting a rubber plastic material to form a closed space, dust is brought into a narrow air duct inlet by high-speed rolling of the rolling brush piece 51 of the rolling brush 5 and negative pressure of air, and the dust exhausts the air out of the system through the filter cavity 31.

The fan 32 rotates to draw air, and negative pressure is formed under the action of the filter shell 33 from inside to outside through the filter element 36. Pressure is transmitted to the performing tip via two channels: the first dust collection air duct 11 is composed of a top plate 121, a soft baffle 1221 positioned at the front part, a soft baffle 1221 positioned at the left side, a side plate 122 positioned at the left side, an arc-shaped bent plate 131, a side plate 122 positioned at the right side, a second dust separation plate 15, a second sub-duct 352 and a filter shell 33; and the second dust collection air duct 14 is composed of a top plate 121, a soft baffle 1221 positioned at the front part, a soft baffle 1221 positioned at the left side, a side plate 122 positioned at the left side, an arc-shaped bent plate 131, a side plate 122 positioned at the right side, a second dust separation plate 15, a filter shell 33, a partition 34 and a dust collection container 2. Under the action of dust raised by the two cleaning disks 41 moving towards each other at the front end, the dust enters the filter cavity 31 through the first dust suction air duct 11 and is adsorbed on the filter element 36, then the serrated shifting sheet 37 and the filter element 36 are in close staggered fit, the filter elements 36 are driven to rub against each other to remove dust under the rotation of the dust vibration motor 38, and then the dust falls to the dust collection container 2 through a dust falling air duct formed by the filter shell 33, the separating piece 34 and the dust collection container 2. And the dust raised by the rotation of the roll brush member 51 falls to the dust collecting container 2 through the second dust suction duct 14 in the same manner.

Further, the air inlet of the fan 32 is butted with the inner side of the filter element 36 (made of new material polytetrafluoroethylene), wherein the cylindrical filter element 36 increases the filtering area to 2 square meters, the matching power of the air volume per minute is 180W, and the air volume is 200m³The DC centrifugal fan of/h ensures that the two are well matched. In addition, sealing strips are used at the other interfaces to increase the sealing performance and reduce wind pressure leakage; the opposite side dust-shaking motor (not shown) rotates at a low speed to drive the filter element 36 to rotate continuously, and continuously beats with the poking plate 37 (wherein the poking plate 37 is made of 90-degree polyurethane, and the surface of the poking plate 37 is provided with sawteeth meshed with teeth of a customized filter), so as to remove dust adsorbed on the filter element 36 during filtering.

In addition, the present invention is not limited to this, since the partition 34 is welded to the filter housing 33 to make both sides asymmetrical, and the second sub duct 352 is also designed as a flare with an outward inclination angle of 30 °, so that a stronger negative pressure can be formed without consuming more power of the blower 32 in terms of aerodynamics, and most of dust can be more effectively adsorbed.

According to the actual working conditions, the fan 32 with the power of 180W and the suction flow of 200m3/h is finally provided, so that the air passing rate of the customized filter element 36 matched with the fan is 200/60-3.3 m3/min per minute, and under the limit that the inner diameter of the designed filter element 36 is 140mm and the outer diameter is 260mm, the side of the final filter element 36 is separated by an angle of 2 degrees, so that the tooth angle of the plectrum 37 is 2.5 degrees.

As shown in fig. 1, M is marked at the position of the plane of the rotation axis of the guide wheel at the front of the cleaning robot 100, wherein the plurality of cleaning plates 41 in the side brush 4 are all disposed lower than M, thereby effectively cleaning the base surface.
