[0045] When using the present invention, first install the installation frame 1 in the building wall through the fixing plate 2 and the installation hole 3, and then rotate and adjust the rotating installation cylinder 50 according to the wind direction of the natural wind outside the building, so that the openings of the rotating installation cylinder 50 and the wind guide cover 51 face the direction of the natural wind, so that the wind guide cover 51 and the wind guide plate 52 guide the natural wind into the rotating installation cylinder 50 and then into the room, thereby playing the role of being able to guide the natural wind into the room and enhancing the indoor air circulation. When guiding the wind, the multi-stage electric push rod 54 can be started according to the indoor ventilation needs, and the guide member 53 can be pushed to move, so that the wind guide cover 51 rotates, and the size of the opening between the wind guide cover 51 and the rotating installation cylinder 50 is adjusted to adapt to different indoor ventilation needs. When ventilating the room, the multi-stage electric push rod 54 can be intermittently controlled to close the wind guide cover 51 and the rotating installation cylinder 50 to achieve intermittent ventilation of the room.

[0046] The air supply mechanism 6 of the present device can adapt to walls of different thicknesses and deliver natural wind to different areas of the room. When the installation frame 1 is installed in the building wall, the corresponding number of first air guide frames 60 and second air guide frames 601 are spliced and installed on the installation frame 1 through the connecting bolts 62 according to the thickness of the wall.

When the wind guide cover 51 and the rotating mounting cylinder 50 are closed, the sliding rod 73 is squeezed forward by the rotating mounting cylinder 50, and the spring 72 is squeezed and contracted. At this time, the conducting hole on the sliding rod 73 is blocked by the conducting member 71, so that the water mist stops spraying. When the wind guide cover 51 is opened, the spring 72 rebounds, driving the sliding rod 73 to reset, so that the conducting hole on the sliding rod 73 is not blocked by the conducting member 71.

[0052] By using the rotating mechanism 9 of the present device, the rotating mounting cylinder 50 can be automatically rotated. When the rotating mounting cylinder 50 needs to be rotated and adjusted, the second motor 90 is started to drive the friction wheel 91 to rotate, so that the friction wheel 91 drives the connecting ring 92 to rotate, and then the rotating mounting cylinder 50 is rotated, thereby enabling the rotating mounting cylinder 50 to rotate automatically and improving the convenience of using the present device.
