The lower end of the discharge pipe 8 is in the shape of a section of cylinder, an inverted truncated cone, and the positioning groove 28-1 is matched with the discharge pipe 8 in shape, so that the positioning groove 28-1 can enable the plugging to be more stable when the discharge pipe 8 is sunk into the isolation plate 12.
The upper end of the positioning boss 28 is close to the through hole 18 formed at the upper end of the discharge pipe 8, so that the flow passage area of air is reduced, and the flow velocity of the air is increased. The sealing ring is arranged at the lower end of the isolation plate 12 to ensure the sealing connection with the positioning ring 5-4, so that the air inlet cavity 10 and the collecting pipe 13 at the lower end of the mesh filter cover 5 are mutually isolated, and the stability of equipment is ensured.
Referring to fig. 8 and 9, a discharging cover 29 at the lower end of the dust cup 4 has one end rotatably connected to the dust cup 4 and the other end detachably connected to the dust cup, and a sealing ring may be added to ensure sealing performance by abutting the lower end of the collecting pipe 13 in the mesh filter cover 5 against the end surface of the discharging cover 29. The outer wall of the dust cup 4 is provided with an elastic buckle 30, the discharging cover 29 is provided with a positioning clamping groove 31 corresponding to the elastic buckle 30, and the sealing and the opening of the discharging cover 29 from the dust cup 4 are realized through the separation and the fixation of the elastic buckle 30 and the positioning clamping groove 31. A sealing ring can be arranged at the lower ends of the discharging cover 29 and the dust collecting cup 4 to ensure the tightness of the discharging cover and the dust collecting cup.
Air flow path: when the suction motor 2 works, negative pressure is formed in the handle 1 and the dust cup 4, the dust collection component 3 starts to suck sundries on the ground, and air enters the dust collection component 3 together. Dust and impurities enter from the air suction pipe 4-4 in the dust cup 4 along with air, cyclone flow occurs in the preliminary filter cavity 5-1 initially, and most impurities are left in the preliminary filter cavity 5-1; the rest enters the air inlet cavity 10 through the mesh filter cover 5, then enters the air inlet pipe 16 and the through hole 18 in the mounting ring 9, then enters the cyclone cavity 11 in the air inlet pipe 16 through the air inlet 17 and the air inlet 19 on the air inlet pipe 16, the air flows along the track of the guide rod 15 in a cyclone way, a part of impurities in the air are centrifugally filtered, and the impurities are subjected to mobile phone through the air inlet pipe 16, the discharge pipe 8 and the collecting pipe 13; the air continues to rise and passes through the filter screen 26, and sundries are filtered and adsorbed again by the filter screen 26; eventually air enters the mounting cover 4-1 and the handle 1, and is discharged from the handle 1 by the suction motor 2.
The present invention is not limited by the specific embodiments, and modifications can be made to the embodiments without creative contribution by those skilled in the art after reading the present specification, but are protected by patent laws within the scope of claims of the present invention.
