[0012] Figure 1 It is a three-dimensional schematic diagram of the air outlet duct of the utility model. DETAILED DESCRIPTION
[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0014] like Figure 1 As shown, the air outlet duct includes a top cover 1 covering the top of the fan, and an opening 11 is provided on the top cover 1, and the opening 11 is opposite to the air outlet of the fan. A motor is provided inside the top cover 1 for sucking the wind from the air outlet of the fan into the air outlet duct, and a control panel 12 is provided on the top surface of the top cover 1 for the user to operate and check the usage of the air outlet duct.
[0015] The opening 11 is provided with a first wind shield 2, which is a funnel-shaped with a narrow bottom and a wide top. The upper end of the top cover 1 is provided with a second wind shield 3, which has a square frame at the bottom and covers the upper end of the top cover 1, a wide-to-narrow middle part, a round top and is provided with a straight air duct 4, the first wind shield 2 is located between the top cover 1 and the second wind shield 3, and the first wind shield 2 and the second wind shield 3 are used to gather wind.
[0016] The straight air duct 4 is a hollow tubular structure, and the cross-section of the straight air duct 4 is circular, which is used to transport the cold air gathered by the first wind hood 2 and the second wind hood 3. A window frame 5 is provided at the upper end of the straight air duct 4, and the cross-section of the window frame 5 is a quadrilateral. Several air outlet windows 51 are provided at intervals around the outer wall of the window frame 5 for outputting cold air, which can ensure that cold air is blown to the surrounding environment. Shutters 6 are provided on the air outlet windows 51 for adjusting and controlling the wind direction; a groove 52 is provided in the middle of the air outlet window 51.
[0017] A compressed air cover 7 is arranged above the window frame 5. The compressed air cover 7 is a quadrilateral. The compressed air cover 7 includes a cover, buckles 71 arranged at intervals on the edge of the cover, and a guide protrusion 72 arranged below the cover. The buckles 71 cooperate with the grooves 52 on the window frame 5 to fix the compressed air cover 7 to the window frame 5. The compressed air cover 7 and the window frame 5 are sealed. A recess is arranged at the guide protrusion 72. The recess is opposite to the air outlet window 51 and is used to guide the cold air to be blown out from the air outlet window 51 to prevent the formation of wind stagnation inside the window frame 5, which leads to a reduction in the amount of air blown out of the air outlet window 51. A cover plate 8 is arranged on the top cover of the compressed air cover 7. The cover plate 8 is connected to the compressed air cover 7 by screws. The cover plate 8 is used for shading, rain protection, etc. to prevent the air outlet duct from being damaged by exposure to the sun or water when it is used outdoors or transported.
[0018] The utility model discloses an air outlet duct which is configured to have an opening of a top cover 1 opposite to the air outlet of the fan, and to install the top cover 1 on the fan.
