Blowing and sucking all-in-one machine

According to the blowing and sucking all-in-one machine, the cup opening of the dust cup is provided with the first air guide part, the second air guide part and the arc-shaped air guide wall, the air inlet is formed between the second air guide part and the arc-shaped air guide wall, and the first air guide part is used for guiding airflow to be converted from the direct flow direction to the oblique airflow facing the arc-shaped air guide wall along the first air guide part; the air flow moves towards the arc-shaped guide wall along the first air guide part, moves towards the air inlet along the arc-shaped guide wall, and finally enters the cup cavity from the air inlet to form rotary air flow or spiral air flow, so that pet hair in the cup cavity forms hair balls under the action of air flow movement, the contact area between the pet hair and the dust blocking cover is reduced, and the dust blocking effect is improved. The pet hair is not easy to attach to the dust blocking cover under the action force of
