Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 1-10, an embodiment of the present invention provides a fan, including: the holding part 100 and a plurality of legs 220, the plurality of legs 220 are respectively hinged with the holding part 100 along the circumferential direction, so that the plurality of legs 220 can be in a combined state or an unfolded state. The plurality of legs 220 are hinged to the holding portion 100, the legs 220 can rotate around the holding portion 100, and when the plurality of legs 220 rotate towards each other and are combined, the plurality of legs 220 are in a combined state, so that a user can hold the legs conveniently; when the fan needs to be placed on a plane, the supporting legs 220 can be turned outwards, so that the plurality of supporting legs 220 are unfolded to form an umbrella shape, and the plurality of supporting legs 220 can support the main body of the fan, thereby freeing the hands of a user.

The hinged part of the supporting leg 220 and the holding part 100 can be provided with a locking screw, the gap between the hinged surfaces of the supporting leg 220 and the support plate 210 can be reduced through the locking screw, and the supporting leg 220 is not easy to naturally rotate through increasing the friction mode.

Further, in order to enhance the aesthetic appearance of the fan, the holding portion 100 includes a bracket plate, a plurality of the supporting legs 220 are respectively hinged to the bracket plate 210 along the circumferential direction of the bracket plate 210, and the bracket plate 210 and the supporting legs 220 may form a supporting assembly 200.

An accommodating cavity 110 with an opening is formed in the grip part 100, and the support plate 210 of the support assembly 200 is slidably connected with the accommodating cavity 110, so that the support legs 220 of the support assembly 200 can be retracted into the accommodating cavity 110; alternatively, the legs 220 of the support assembly 200 can extend from the receiving cavity 110.

The depth of the accommodating cavity 110 is matched with the length of the supporting component 200, the supporting component 200 can slide into the accommodating cavity 110, the appearance is cleaner, simpler and more elegant, redundant and complex details can be hidden in a visual blind area, and the human engineering is met. The bracket is convenient to slide in or out of the accommodating cavity 110, and the shape of the fan is convenient to change.

In order to avoid the support assembly 200 from slipping out of the accommodating cavity 110, the supporting legs 220 are provided with elastic protrusions 221 protruding towards the inner side of the supporting legs 220, when the supporting legs 220 are in a combined state, the elastic protrusion 221 on each supporting leg 220 can abut against the supporting leg 220 opposite to the supporting leg 220, the elastic protrusion 221 is compressed, the elastic protrusion 221 tends to restore the original shape, the elastic protrusion 221 pushes the supporting leg 220 where the elastic protrusion is located and the protrusion abutting against the elastic protrusion 221 in the opposite direction, so that the supporting legs 220 tend to expand, at this time, the supporting legs 220 are in the accommodating cavity 110, the supporting legs 220 expand outwards and abut against the inner wall of the accommodating cavity 110, and therefore the friction force between the supporting legs 220 and the accommodating cavity 110 is increased, and the probability that the support assembly 200 slips out of the accommodating cavity 110 is reduced.
