[0032] The following is combined with Figures 1 to 7 The technical solution of the utility model is further illustrated by specific implementation methods.

[0033] A folding humidifying fan, such as Figure 1-4As shown, it includes a base 1, a fan body 2, a humidifying component 3, a water tank 4 and a main control board, wherein the main control board and the water tank 4 are respectively arranged inside the base 1, and the main control board is electrically connected to the fan body 2 and the humidifying component 3;

[0034] The top of the base 1 is divided into a first area 01 and a second area 02 adjacent to each other; the base 1 is provided with the humidifying component 2 in the first area 01, the humidifying component 2 is provided with a mist outlet 12, the mist outlet 12 is exposed in the first area 01, and the humidifying component 2 is used to spray the water in the water tank 4 into atomized water;

[0035] The fan body 2 is rotatably and foldably installed on the top of the base 1. When the fan body 2 is in a folded state, the air outlet surface of the fan body 2 is against the first area 01; when the fan body 2 is in an unfolded state, the fan body 2 and the base 1 are perpendicular to each other, the bottom of the fan body 2 is against the second area 02, and the air outlet surface of the fan body 2 faces the atomization area of ​​the humidification component 2.

[0036] Specifically, the fan body 2 is rotatably and foldably mounted on the top of the base 1. When the fan body 2 is in a folded state (refer to Figure 3 and Figure 4 ), the air outlet surface of the fan body 2 is against the first area 01, which reduces the occupied space and is easier to store or carry. Figure 1 and Figure 2 ), the fan body 2 and the base 1 are perpendicular to each other, the bottom of the fan body 2 is against the second area 02, and the fan body 2 is stably supported on the base 1, which prevents the fan body 2 from tipping over and causing the wind direction to shift, and prevents the fan body 2 from rotating easily, so that it can be maintained stably when blowing.

[0037] In addition, the humidifying component 3 and the water tank 4 are arranged inside the base 1, so that the appearance is simple and beautiful. Specifically, the base 1 is equipped with the humidifying component 2 in the first area 01, and the humidifying component 2 is provided with a mist outlet 12, and the mist outlet 12 is exposed in the first area 01. When the fan body 2 is in a non-folded state, the air outlet surface of the fan body 2 faces the atomization area of ​​the humidifying component 2. When working, the humidifying component 3 forms water mist from the water tank 4 and sprays it at the mist outlet 12.
