Abstract
Claims
1. An air supply device, characterized by, include: The housing has a bottom wall and a side wall circumferentially disposed around the bottom wall. The side wall and the bottom wall together enclose a receiving cavity. The side wall has a first air outlet and a second air outlet that are spaced apart along its circumference. A first air outlet assembly is installed inside the receiving cavity, and the air outlet of the first air outlet assembly is connected to the first air supply outlet. The second air outlet assembly is disposed in the receiving cavity and rotates circumferentially along the side wall, and can switch between the first air outlet state and the second air outlet state. In the first air outlet state, the air outlet of the second air outlet component faces into the receiving cavity and is connected to the first air supply port; in the second air outlet state, the air outlet of the second air outlet component is connected to the second air supply port.
2. The air supply device according to claim 1, wherein The second air outlet assembly includes a first air outlet and a second air outlet. The first air outlet and the second air outlet are spaced apart on the bottom wall and are both circumferentially rotated along the side wall. The first air outlet and the second air outlet are both provided with air outlets. The orientation of the air outlet of the first air outlet is different from that of the air outlet of the second air outlet. There are two second air outlets, which correspond one-to-one with the first air outlet and the second air outlet.
3. The air supply device according to claim 2, wherein When the second air outlet component is in the second air outlet state, the included angle formed between the air outlet of the first air outlet component and the air outlet of the second air outlet component is an obtuse angle.
4. The air supply device according to claim 2, wherein When the second air outlet component is in the first air outlet state, the included angle formed between the air outlet of the first air outlet component and the air outlet of the second air outlet component is an acute angle.
5. The air supply device according to claim 2, wherein The rotational movements of the first and second air outlet components are linked.
6. The air supply device according to claim 5, wherein The air supply device further includes a driving component, a first transmission component, and a second transmission component. The driving component is drivingly connected to the first transmission component and the second transmission component. The first transmission component is connected to the first air outlet component, and the second transmission component is connected to the second air outlet component.
7. The air supply device according to claim 1, wherein The air supply device further includes a first air inlet component and a second air inlet component, which are spaced apart from each other in the height direction on the housing.
