Specifically, the casing includes lower cover 1 and protecgulum 2, and lower cover 1 is located both sides and the rear side of dust absorption mouth are provided with horizontal mounting groove 6 and two vertical mounting grooves 4 on the lower cover 1, and horizontal mounting groove 6 is located the dust absorption mouth rear side, two vertical mounting grooves 4 are located respectively the both sides of dust absorption mouth, and horizontal sealing strip 7 bonds in horizontal mounting groove 6, and two vertical sealing strips 5 bond respectively in two vertical mounting grooves 4, and vertical mounting groove 4 includes from back to front first groove 41, second groove 42 and third groove 43, and first groove 41 aligns with the medial side 8 of lower cover 1, and third groove 43 aligns with the lateral side 9 of lower cover 1, and two vertical sealing strips 5 form first section 51, second section 52 and the third section 53 that correspond with first groove 41, second groove 42 and third groove 43 respectively, and horizontal sealing strip 7 forms a wide dust absorption space that is narrow in front and back together with two vertical sealing strips 5. The term "alignment" as used herein means that the first groove 41 and the third groove 43 are located as close to the inner side 8 and the outer side 9 of the lower cover, respectively, as possible under conditions satisfying processing and installation.
Further, the front cover 2 is arc-shaped, the lower side edge of the front cover 2 is in butt joint with the front side edge of the lower cover 1 at A, the tangent line of the arc of the front cover 2 at A is intersected with the plane of the lower cover 1 to form an included angle alpha, the value range of the included angle alpha is more than or equal to 0 and less than or equal to 75 degrees, if the included angle alpha is more than 75 degrees, large-particle dust is not easy to be sucked into the ground brush from two sides, friction is easy to be generated with the ground when the ground brush is pulled back, and dust collection effect is affected.
Further, the distance between the front end of the third groove 43 of the vertical installation groove 4 and the lower side edge of the front cover 2 is 0 to 5mm, that is, in the case that the processing condition is satisfied, the front end of the third groove 43 may be as close to the lower side edge of the front cover 2 as possible, or the front end of the third groove 43 may be directly aligned with the lower side edge of the front cover 2. The axis Y of the rolling brush 3 passes through the intersection point of the inner side edge of the second section 52 and the inner side edge of the third section 53, the intersection point of the inner side edge of the second section 52 and the inner side edge of the third section 53 is an included angle beta, and the included angle beta has the following value range: the angle beta is more than or equal to 100 degrees and less than or equal to 170 degrees, the axis Y of the rolling brush 3, the transverse sealing strips 7, the first sections 51 and the second sections 52 of the two vertical sealing strips 5 form a quasi-closed dust collection area with higher vacuum degree, and the axis Y of the rolling brush 3 and the third sections 53 of the two vertical sealing strips 5 form a dust guide area. Here, the term "quasi-closed" means that the outer periphery of the dust collection area forms a fully sealed structure, but a gap exists between the vertical seal 5 and the roller brush 3. The reason why the position of the axis Y of the roller brush 3 is used as one of the boundaries of the suction area is that the suction efficiency is related to the vacuum degree of the suction area, and the higher the vacuum degree is, the better the suction effect is, while the contact point of the roller brush 3 at the contact position with the ground is in a vertical plane with the axis Y of the roller brush itself, which, together with the transverse sealing strip 7 and the first and second sections 51, 52 of the vertical sealing strip 5, just forms a sealing area with a higher vacuum degree. Due to the fact that the third section 53 and the second section 52 of the vertical sealing strip 5 are arranged, a guiding structure with wide front and narrow rear is formed, dust in the dust guiding area can be better guided to a dust collecting area which is sealed in a quasi-mode, namely, part of dust in the dust guiding area rolls into the dust collecting area through the rolling brush 3, and part of dust is sucked into the dust collecting area through gaps between two ends of the rolling brush 3 and the vertical sealing strip 5.
