The utility model adopts the technical proposal that: a portable fan with a base capable of adjusting angles comprises a fan body and a base body, and is characterized in that the fan body comprises a fan face shell, fan blades, a control circuit board, a battery and a fan back shell, the fan face shell and the fan back shell form a handheld handle part and a fan cover cavity for mounting the fan blades, and the battery and the control circuit board are mounted in the handheld handle part; the fan base is characterized in that a concave part is arranged in the base body, the bottom end of a handheld handle part of the fan body is inserted into the concave part, the base body comprises a movable upper shell and a fixed bottom shell, the movable upper shell is composed of a first upper shell and a first lower shell, an opening is formed in the first upper shell, two side edges of the first lower shell are downwards provided with L-shaped buckles, a lower concave part is arranged in the first lower shell, a protruding end is arranged at the bottom of the lower concave part, and a hollow body is arranged in the protruding end. The fixed bottom shell is composed of a second upper shell and a second lower shell, sliding grooves are formed in two side edges of the second upper shell, the second upper shell is also concave, and a row of protruding clamping gears are arranged at the bottom in the second upper shell. The L-shaped buckles on two sides of the first lower shell are clamped in the chutes on two sides of the second upper shell, the bottom of the convex end in the first lower shell is meshed with the convex end of the convex clamping gear in the second upper shell, and the first lower shell and the second upper shell are integrally arc-shaped. The arc-shaped design is adopted, so that the fan body inserted in the first upper shell and the first lower shell can change the pitching angle when the first lower shell and the second upper shell slide.

And the first upper shell and the first lower shell are fixedly connected through screws, and the second upper shell and the second lower shell are fixedly connected through screws.

Furthermore, the fan surface shell and the fan back shell are integrally formed.

Further fan housing intracavity border that fan face-piece and fan backshell are constituteed is equipped with a LED lamp ring, LED lamp ring and control circuit board electric connection, control circuit board is equipped with a fan control button and LED lamp control button, and control circuit board is equipped with the interface that charges.

The utility model has the advantages that: through the portable fan with angle regulation base that this technical scheme designed, fan body and the split type connection of base body realize that the fan body not only can hand the use, can peg graft in the base body and place the desktop in addition and use to liberation both hands. Compared with the portable small fan with the base in the prior art, the base in the prior art is fixed, and the pitch angle of the fan inserted on the base cannot be adjusted, so that when the height of the desktop is not suitable for use, the fan is placed on an overhigh desktop or an overlow desktop for use, and the effect is not ideal. And the base body that this technical scheme designed just can solve above-mentioned problem, and its base equals to have two parts that can slide to constitute, and these two parts design have certain radian, like this when two parts are interactive, can change the pitch angle of the fan body of pegging graft in it to more can satisfy people's user demand. Simultaneously, this internal round LED lamp that is equipped with of fan, it can realize acting as little night-light and use.
