Furthermore, one end of the first air duct 120 is communicated with the outside, the other end of the first air duct 120 is communicated with the inlet of the injection air duct 110, and the outlet of the injection air duct 110 is the air outlet 111 communicated with the outside. The fan assembly 200 is installed in the housing 100, and the wind bundle generated by the operation of the fan assembly 200 flows from the first wind path 120 to the wind outlet 111. The axis of the injection air duct 110 is set as a straight line, the axis of the first air duct 120 is also set as a straight line, and the two straight lines are designed to be collinear (due to manufacturing errors and installation errors, the two straight lines may deviate after the actual assembly process).
This air treatment device, fan unit 200 moves, and outside air gets into in the first wind channel 120 from the one end in first wind channel 120 and forms the wind bunch, and the wind bunch gets into injection wind channel 110 after first wind channel 120, and the wind bunch is by the pressure boost in injection wind channel 110, and the wind bunch speed after the pressure boost increases and finally jets from air outlet 111, and the wind bunch speed of jetting from air outlet 111 is faster like this, blows the distance farther, therefore user's the impression of blowing is better.
