[0032] Referring to the accompanying drawings Figures 1-2 The dust collector dust collection air duct structure in the embodiment includes a hollow dust collection air pipe 1, and specifically, the dust collection air pipe 1 is vertically arranged; the upper and lower ends of the dust collection air pipe 1 are respectively provided with a dust inlet 6 and a dust outlet 7; the dust inlet 6 is in communication with a dust suction port at the bottom of a dust cup of the dust collector; when the dust suction port at the bottom of the dust cup is in contact with the dust inlet 6, dust in the dust cup can enter the dust collection air pipe 1 from the dust inlet 6.

[0033] In some embodiments, the dust inlet 6 on the dust collection channel and the dust suction port are matched in shape and size, so that when the dust enters the dust collection air pipe 1 from the dust cup, the dust does not escape from the connection between the two.

[0034] The dust inlet 6, the inner wall of the dust collection air pipe 1 and the dust outlet 7 form a dust collection channel for the flow of dust in the dust cup, and the dust collection channel is coaxially arranged with the dust suction port. This can more efficiently suck the dust from the dust cup into the dust collection air pipe 1, reduce the loss, and prevent the dust from being blocked at the connection between the dust cup and the dust inlet 6.

[0035] Referring to the accompanying drawings Figure 1 The caliber of the dust collection air duct gradually decreases from the dust inlet 6 to the dust outlet 7. This can guide the dust entering the dust collection air pipe 1 to quickly enter the dust collection barrel 9 under the suction of the subsequent dust collection mechanism, thereby effectively improving the dust suction efficiency.

[0036] In some embodiments, the dust collection air duct is in the shape of a funnel. The surface of the dust collection air duct is smooth, which can effectively prevent the dust from sticking to the wall during the dust collection process, improve the dust suction efficiency, and also enable the user to clean the dust collection air duct less frequently, thereby improving the convenience of use.
