Referring to fig. 1 and 2, the present invention provides a fan assembly, including: the machine shell 20 is provided with an inner cavity 21 and an air inlet channel 25 communicated with the inner cavity 21; the fan body 22 is arranged in the inner cavity 21 and is provided with an air inlet 23 communicated with the air inlet duct 25; the air purification module 27 is installed in the air inlet duct 25, and the air purification module 27 partially shields the air inlet duct 25, so that a first air path 251 through which an air flow enters the air inlet 23 after flowing through the air purification module 27 and a second air path 252 through which the air flow directly enters the air inlet 23 are formed in the air inlet duct 25; the first adjusting plate 28 is movably installed in the air inlet duct 25, and the first adjusting plate 28 has an air supply state for opening the second air path 252 and a purification air supply state for closing the second air path 252.
The housing 20 serves as an outer casing of the fan assembly, and a hollow structure is formed inside the housing, and serves as the inner cavity 21. The blower body 22 is installed in the inner cavity 21, and when the blower body 22 operates, airflow enters the air inlet 23 from the air inlet duct 25.
The air purification module 27 is configured to filter the airflow entering the air inlet duct 25, and the air purification module 27 blocks a portion of the air inlet duct 25, so that the airflow passing through the air purification module 27 is purified and then delivered to the air inlet 23. When the air flow passes through the air purification module 27, the air purification module 27 will block the air flow to some extent, and will generate some wind resistance to the air flow.
The first adjusting plate 28 is a baffle structure disposed in the air inlet duct 25 for blocking air flow. When the first adjusting plate 28 is in the air supply state, the air flow directly enters the air inlet 23 from the second air path 252, so that direct air supply is realized. When the first adjusting plate 28 is in the purifying air supply state, the second air path 252 is closed by the first adjusting plate 28, so that the air flow can only flow to the air inlet 23 through the air purifying module 27, and the purified air supply is realized.
The air purification module 27 has a windward side and a leeward side, and the air flow passes through the air purification module 27 from the windward side for purification and is output from the leeward side. When the first damper 28 is in the air supply state, the first damper 28 may shield the windward side of the air purification module 27, so that the air flow does not flow to the air purification module 27 at all but flows directly to the air inlet 23.
