Through setting up spacing step, on the one hand can limit separation blade structure d304 motion stroke, avoid separation blade structure d304 to bump with inlet channel's inner wall in the motion process, impact damages inner wall or separation blade structure d304, also avoid separation blade structure d304 to move and surpass the control stroke of elastic component, improve separation blade structure d 304's life, on the other hand, set up like this, can be when separation blade structure d304 is in the open mode, form the water conservancy diversion structure with the spacing step d103 of dirt cup separation blade, and then form the water conservancy diversion passageway tangent with dust collection chamber d4 inside wall with the inner wall of second back end d115 that admits air, realize gaseous flow direction adjustment, the centrifugal separation to dirt in the gas has been realized.

In this embodiment, a plurality of ribs of different types are disposed along the periphery of the second air intake rear section d115, wherein a first rib disposed in a concave shape is further disposed on the outer wall of the second air intake rear section d115, and is disposed on the top side of the air intake end, and penetrates through the outer wall of the dust cup body d1, and a first routing portion d104 of the dust cup with an upward opening is disposed thereon, so as to accommodate and guide the direction of the electric wire. Two second reinforcing ribs are further arranged on the periphery of the outer wall of the second air inlet rear section d115, the second reinforcing ribs are arranged to be attached to the arc-shaped outer wall of the second air inlet rear section d115 and are connected with the outer wall of the dust cup body d1 and the outer wall of the second air inlet rear section d115, and a second notch-shaped dust cup routing portion d105 is arranged on the second notch-shaped dust cup routing portion and is suitable for guiding a lead to turn. A third reinforcing rib is further arranged along the lower side of the outer wall of the second air inlet rear section d115, the third reinforcing rib is also positioned in the extending direction of the air inlet channel at the inner side of the air inlet connecting port d302, and a third routing portion d106 of the dust cup is arranged on the third reinforcing rib. In addition, a fastening rib is disposed along the outer wall of the second air intake rear section d115, and is fastened and fixed with the inner wall of the air intake connecting portion d301, and a dust cup fourth routing portion d107 is disposed on a side of the fastening rib facing the second air intake front section d 114.

The first routing portion d104, the second routing portion d105, the third routing portion d106 and the fourth routing portion d107 form part of the wire-passing channel.

As an alternative embodiment, one or more of the first stiffener, the second stiffener, the third stiffener, and the fastening rib may be disposed, or one or more of the first routing portion d104, the second routing portion d105, the third routing portion d106, and the fourth routing portion d107 may not be disposed.

In addition, a dust cup mounting and positioning rib d102 is further arranged on the air inlet connecting part d301 along the circumferential direction of the second air inlet rear section d115, so that the air inlet connecting part d301 is fixedly connected with the dust cup body d 1. As an alternative embodiment, the dirt cup mounting and positioning rib d102 may be provided only on the air inlet connection portion d301 or the second air inlet rear section d 115.

In this embodiment, an annular air inlet limiting portion d312 is disposed at an inner edge position of the first air inlet section d307 adjacent to the second air inlet section d101, and an air inlet gasket d310 is fitted to the air inlet limiting portion d 312. The arrangement of the air inlet sealing gasket d310 can provide a buffering effect and a sealing effect for the connection of the dust cup assembly and other external assemblies at the first air inlet section d307, so that the collision and damage caused during connection are avoided, and the sealing performance of the dust cup assembly is improved.

In addition, an air inlet end cover d306 is further arranged at one end, back to the air inlet connecting portion d301, of the air inlet connecting port d302, the air inlet end cover d306 is fixed between the inner wall of the air inlet connecting port d302 and the outer wall of the first air inlet section d307, a notch which is arranged in the waist-shaped hole in a yielding mode is formed in the top end of the air inlet end cover d306, and screw holes fixed with screw columns are formed in the two sides of the.

Air inlet subassembly d3 still includes air inlet terminal support d303, sets up in the line passageway of crossing in air inlet connecting portion d301, and this department crosses and is provided with air inlet terminal support and holds chamber d311 in the line passageway, can hold air inlet terminal support d303, and air inlet terminal support d303 and the breach block connection of air inlet end cover d306 downside are provided with the air inlet inside and cross line hole d309, are suitable for setting up the wire.

The outer wall of the dust cup body d1 is also provided with a plurality of screw columns along the circumferential direction of the air inlet channel, and the screw columns are fixedly connected with the air inlet connecting part d 301.

The embodiment also provides a dust collector which comprises the dust cup assembly, the dust collection pipe and the dust collector head. One end of the dust suction pipe is connected with the air inlet component d3 of the dust cup component, and the dust collector head is connected with the other end of the dust suction pipe. After the dust cup subassembly starts, the vacuum motor work of dust catcher produces the negative pressure, and the negative pressure will be through the dust absorption pipe suction dust cup subassembly with dirt through the dust catcher head to the realization is to the accomodating of dirt self.
