Detailed Description

Referring to fig. 1 to 3, a specific structure of a preferred embodiment of the present invention is shown, including a water storage bottle 10, a bracket 20, a motor 30 and fan blades 40.

The water storage bottle 10 is provided with a spray head 50, the spray head 50 is communicated with the inside of the water storage bottle 10 through a spray pipe 51, and the spray head 50 is provided with a spray head 52 and a handle 53 for controlling the spray head 52 to spray. In this embodiment, the water storage bottle 10 includes a bottle body 11 and a bottom cover 12, the spray head 50 is disposed on the top of the bottle body 11, an opening 101 is formed at the bottom of the bottle body 11, the bottom cover 12 covers the opening 101, the bottom cover 12 is screwed with the bottle body 11, and a gasket 13 is interposed between the bottom cover 12 and the bottle body 11 for sealing.

The bracket 20 is fixed on the water storage bottle 10; the motor 30 is fixed on the bracket 20; the bracket 20 comprises a front body 21 and a back body 22, the back body 22 is installed at the back side of the front body 21, and the motor 30 and the spray head 50 are both clamped between the front body 21 and the back body 22; a battery cavity 201 is concavely provided on the rear side of the rear body 22, the battery cavity 201 is covered by a battery cover 23, a battery 61 is embedded in the battery cavity 201, and the battery 61 is conductively connected with the motor 30 through a positive plate 62 and a negative plate 63.
