In the embodiment of the application, as shown in fig. 1 to 4, the connecting piece 1 further comprises a limiting arm 11, the dust collecting bag and the dust collecting barrel 4 perform relative movement, the limiting arm 11 is arranged on the side wall of the connecting piece 1 near one end of the dust outlet 12, when the dust collecting barrel 4 is in a cleaning state, due to the elasticity of the rubber sleeve 3, the limiting arm 11 is in interference fit with the dust collecting bag so as to drive the connecting piece 1 to swing, the dust outlet 12 is removed from the dust collecting bag, meanwhile, the elastic element 2 contacts with the inner wall 45 of the dust collecting barrel to deform, and after the dust collecting bag is taken out, the elastic element 2 is reset to force the connecting piece 1 to return to the original position.
In the above embodiment, as shown in fig. 7 to 9, the limiting arm 11 includes the protruding portion 111, the protruding portion 111 is located on the side of the limiting arm 11 near the dust outlet 12 and above the dust outlet 12, wherein the protruding portion 111 has an angular protrusion protruding in the opening direction of the dust outlet 12.
As shown in fig. 7 and 8, when the dust collecting barrel 4 is in a dust collecting state, the limiting arm 11 abuts against the dust bag fixing plate 43 of the dust collecting barrel 4 under the action of the elastic element 2, so that the protruding part 111 is positioned in the dust collecting cavity 41 of the dust collecting barrel 4, that is, in order to ensure smooth removal of the dust collecting bag and ensure the air tightness of the dust collecting barrel 4 during operation, certain requirements are required for the protruding part 111, the dust outlet 12 and the whole height of the connecting piece 1, firstly, in order to meet the air tightness requirements during dust collection, the dust outlet 12 of the connecting piece 1 must extend into the dust collecting bag during the dust collecting state, and meanwhile, the elastic element 2 is ensured to abut against the dust bag fixing plate 43, so that the connecting piece 1 can abut against the inner wall 45 of the dust collecting barrel without shaking.
As shown in fig. 7 and 9, when the dust collection barrel 4 is in a cleaning state, the dust collection bag abuts against the protruding portion 111 in the process of relative movement with the dust collection barrel 4, so that the limiting arm 11 is driven to move away from the dust collection cavity 41 by the protruding portion 111, the limiting arm 11 drives the connecting piece 1 to move integrally in the direction away from the dust collection cavity 41, namely, when the dust collection bag is taken out through upward extraction, the dust collection bag presses the protruding portion 111, and the connecting piece 1 moves in the direction away from the dust collection bag fixing plate 43, so that the dust collection bag is smoothly extracted.
It should be noted that, when the protrusion 111 moves to the vertical position of the dust bag fixing plate 43 of the dust collecting barrel 4, the bottom end of the dust outlet 12 is flush with the protrusion 111 in the vertical direction, or the bottom end of the dust outlet 12 is located at one side of the protrusion 111 away from the dust bag fixing plate 43 in the vertical direction, that is, when the dust bag is taken out, the protrusion 111 of the connecting member 1 may be aligned with the vertical direction of the bottom end of the dust outlet 12 in the vertical direction, or be closer to the dust bag fixing plate 43, and the vertical position of the protrusion 111 cannot lag behind the vertical position of the bottom end of the dust outlet 12, otherwise, the phenomenon that the dust bag is caught by the dust outlet 12 when taken out occurs.
Therefore, in order to avoid the above-mentioned phenomenon that the dust bag is caught by the dust outlet 12 when being taken out, the connector 1 should satisfy the following relationship:
As shown in fig. 8, the protrusion 111 is located at a point a, the bottom end of the dust outlet 12 is located at a point B, the theoretical rotation center point of the connector 1 is defined as a point O, the horizontal distance between the point O and the vertical position of the dust bag fixing plate 43 is defined as LO, the horizontal distance between the point a and the dust bag fixing plate 43 is defined as LA, the linear distance between the point O and the point a is defined as LOA, and the rotation angle θ when the dust bag is taken out can be expressed by the following formula:
θ=arcos(LO/LOA)-arcos((LO+LA)/LOA);
Therefore, when designing the connecting piece 1, interference between the connecting piece 1 and the inner wall of the dust loading barrel caused by overlarge rotation angle θ should be avoided, so that the dust bag is difficult to take out.
As shown in fig. 9, assuming that the horizontal distance between the protrusion 111 (i.e., point a) and the bottom end of the dust outlet 12 (i.e., point B) is L, and the vertical distance between the protrusion 111 (i.e., point a) and the bottom end of the dust outlet 12 (i.e., point B) is L1, the following relationship exists:
arctan (L/L1) > θ, i.e., arctan (L/L1) > arcos (LO/LOA) -arcos ((lo+la)/LOA);
If the above relationship is not satisfied, when the protrusion 111 is pushed to the vertical position where the dust bag fixing plate 43 is located during the removal of the dust bag, the bottom end of the dust outlet 12 is not completely retracted to the side of the dust bag fixing plate 43 adjacent to the inner wall 45 of the dust loading barrel, so that the dust bag interferes with the dust outlet 12 during the removal, resulting in difficulty in removal.
Optionally, the connecting piece 1 includes two limiting arms 11, where the two limiting arms 11 are symmetrically disposed and extend to two sides of the dust outlet 12 to form a wing-shaped structure.
