The water inlet pipe 7 is used to add water to the humidifier 6. The humidifier 6 is located at the air outlet of the fan 105. The air blown by the fan 105 and the humidifying spray from the humidifier 6 are mixed and blown out, which increases the air humidity and enhances the cooling sensation of the air blown.
[0036] In some embodiments, the fan 105 is a mixed-flow fan, which increases static pressure, increases the fan outlet distance, and is compatible with the humidifier 6 to improve the humidification diffusion range.
[0037] like Figure 3 As shown, the humidifier 6 includes a front cover 601, a rear cover 602, a humidification pipe 603, humidifying cotton 604, an atomizing plate 605, a spring 606, and a humidification cover plate 607. The front cover 601 and the rear cover 602 are detachably and sealingly connected, and the detachability includes, but is not limited to, threaded tightening. The cavity formed between the front cover 601 and the rear cover 602 is a water storage chamber for storing water. A mist outlet is provided in the middle of the front cover 601. The humidification pipe 603 has an output port and an input port. The humidifying cotton 604 is filled inside the humidification pipe 603. The atomizing plate 605 is located at the output port of the humidification pipe 603, and the input end of the atomizing plate 605 is connected to the humidification pipe. Corresponding to the output port of 603, spring 606 is located at the end of humidification pipe 603 away from the output port of humidification pipe 603.

The output end of atomizing plate 605 is connected to the mist outlet of water tank front cover 601 with a limiting seal. After the water tank front cover 601 and water tank rear cover 602 are installed, the atomizing plate 605, humidification pipe 603 and spring 606 are squeezed and fixed. The inner middle of the water tank rear cover 602 is provided with a limiting protrusion for limiting the spring 606. Humidification cover plate 607 is detachably installed on the outside of the mist outlet of water tank front cover 601. Detachable installation includes but is not limited to fixing with screws.
[0038] A water inlet is provided on the side wall of the front cover 601 of the water tank. The output end of the water inlet pipe 7 is sealed and inserted into the water inlet of the front cover 601 of the water tank, so as to achieve a sealed connection between the water inlet pipe 7 and the water storage chamber of the humidifier 6. A sealing cap 8 is sealed and inserted into the input end of the water inlet pipe 7 for sealing the input end of the water inlet pipe 7.
[0039] It also includes a fixed bracket 10, through which the humidifier 6 is fixedly installed to the air duct 101.
[0040] like Figure 1 and 2 As shown, a through hole is provided in the middle of the front mesh cover 104, so that the humidifier cover plate 607 can be exposed after the humidifier 6 is installed to realize the output of humidifying spray.
[0041] like Figure 8 As shown, the humidifying pipe 603 includes a horizontal pipe 13 and a vertical pipe 14.

After the mesh cover mounting frame 103 and the air duct 101 are installed, the first through hole 11 and the second through hole 12 correspond to each other.
[0043] like Figure 4 and 5As shown, after the air duct 101 and the mesh cover mounting frame 103 are installed, the first through hole 11 and the second through hole 12 are located at the upper part of the head 1. That is, the water injection pipe 7 passes through the first through hole 11 and the second through hole 12 in sequence at the upper part of the head 1 and is inserted into the water inlet of the humidifier 6. The widened input end of the water injection pipe 7 is limited to the outside of the mesh cover mounting frame 103 to ensure the stable installation of the water injection pipe 7. The sealing cover 8 is installed at the input end of the water injection pipe 7 and is also located on the outside of the mesh cover mounting frame 103. When the humidifier 6 is short of water, the sealing cover 8 is opened to inject water into the humidifier 6. The water injection pipe 7 is located at the upper part of the humidifier 6 with the input end facing upward, which facilitates the water injection operation and avoids water leakage during the use of the fan.
[0044] like Figure 4 , 6 As shown in Figure 7, several guide plates 9 are provided on the inner side of the air duct 101. The guide plates 9 are arranged in a circular array with the center of the air duct 101 as the center.
