When the blowing fan 10 stops, the one-way exhaust plate 3 adheres to the limiting plate 13 due to gravity, thereby covering the exhaust hole on the lamp cover body 4, further preventing dust and improving protection.

[0044] A method for operating a concealed fan light, referring to... Figure 1 The working method is applied to the above-mentioned concealed fan light, and the working method includes the following steps:

[0045] S1. When blowing air downwards, the motor 19 rotates and drives the air blower 10. The turbine 21 is connected to the motor 19 through the worm gear 20 and rotates. At this time, the arc-shaped movable baffle 26, which is rotated on the fixed column 25, is squeezed by gravity and the limit strip 30 when it flips. In conjunction with the connecting column 28 and the connecting rod 31, it drives the pressure block 32 to rotate, thereby reciprocatingly squeezing the inclined push block 15. At the same time, in conjunction with the guide rod 17 and the spring 18, it reciprocally pushes the movable air intake plate 5 open to achieve air intake.

[0046] S2. The limiting block 33 set on the movable air intake plate 5, together with the fixing block 34 on the air guide turntable 7, controls the speed-limited rotation of the air guide turntable 7, so that the air is blown out more concentratedly.

[0047] S3. When blowing air upwards, the motor 19 rotates in the opposite direction, the turbine 21 rotates in the opposite direction, and the arc-shaped movable baffle 26 set on the fixed column 25 enters the receiving groove 27 after contacting the limit strip 30. It does not perform the reciprocating pushing action on the movable air intake plate 5, and the gas enters from the air guide turntable 7.

[0048] S4, the gas generated in the lampshade body 4 pushes the one-way exhaust disc 3 to rotate along the first rotating shaft 12, and the one-way exhaust disc 3 covers the exhaust hole on the lampshade body 4 after stopping blowing.

[0049] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit the present application; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalent features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
