Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings of the description.

The ceiling fan shown in Figure 1-3 includes:

The circular housing 01 has a circular accommodation chamber 11 inside, and its outer peripheral edge has an annular slit facing downwards (the orientation is determined by the installation and use state, the same below) as the air outlet 12, and the center of the lower end has a through hole as the air outlet. The air inlet 13, the air outlet 12, and the air inlet 13 are connected to the circular accommodation chamber 11;

Motor 02, which is located in the circular accommodation cavity and fixedly assembled on the housing (specifically, assembled on the inside of the first wind deflector 14 mentioned below), and its output shaft extends downward;

The centrifugal wind wheel 03 shown in Figure 6 is located in a circular housing chamber, with an air suction port facing the air inlet on one axial side (the lower side when in use), and the other axial side (the upper side when in use) The central part is provided with a receiving groove and the receiving groove is sleeved on the motor, and the output shaft of the motor is connected with the centrifugal wind wheel.

The ceiling fan is rotated by the motor with the wind wheel, so that the indoor air is sucked in from the air inlet and discharged from the air outlet, forming a 360° circular air outlet.

Specifically, in order to facilitate manufacturing and assembly, the circular shell is assembled by the first wind deflector 14 (see Figure 4) and the second wind deflector 15 (see Figure 5). The first wind deflector 14, the second wind deflector The wind plates 15 are all circular, the edges of the first wind guide plate 14 and the second wind guide plate 15 keep a distance to form the air outlet 13 , and the air inlet 12 is located at the center of the second air guide plate 15 . In order to keep the distance between the edges of the first wind deflector and the second wind deflector, a support column 16 is provided on the first wind deflector, and this support is also used to fasten the first wind deflector and the second wind deflector Mounting position for assembled screws.

The first wind guide plate 14 is a curved surface with its center of curvature located at its lower side; the second air guide plate 15 is curved with its center of curvature located at its lower side. In order to achieve the best circular air outlet effect, the included angle between the first air deflector and the second air deflector and the horizontal plane is 30-60º, preferably 45º; the width of the annular slit is 5-10mm, preferably 6mm.

In order to avoid dust sticking to the exposed ceiling blades, the dust will be blown away when it is opened, causing the indoor air to be turbid, and the coverage area is small, and the airflow cannot circulate the entire space. The air inlet of the circular housing 01 will be assembled The filter device 04 covered by the tuyere is used to filter the passing air. Specifically, the filtering device 04 includes a filter screen 41 and a net cover 42. The net cover 42 is cylindrical and its lower end is closed, and ventilation holes 43 are arranged on the surrounding wall. The filter screen 41 is annular and placed in the net cover 42. The cover is assembled at the air inlet. In order to facilitate assembly and disassembly to replace the filter screen, the circular shell is provided with an arc-shaped connecting rib 17 at the air inlet (specifically, on the second air guide plate), and the mesh cover is connected to the connecting rib through an arc-shaped connecting groove. .

The upper side of the circular housing is provided with installation structures for the ceiling fan, such as lifting holes, suspension rings, etc., for installing the ceiling fan on the ceiling.

In order to realize the function of the LED lamp at the same time, an LED lamp is installed in the circular accommodation cavity.

The ceiling fan is suitable for installation in restaurants, bedrooms and other occasions.
