Abstract
Disclosed is a liftable and foldable electric fan. The liftable and foldable electric fan comprises a base, a middle column and fan blades. The middle column is divided into an upper middle column and a lower middle column. A long hole is formed in the front surface of the upper middle column, and two threaded holes are formed in the front surface of the lower middle column. The upper middle column and the lower middle column are connected through two hand screws. The height of the liftable and foldable electric fan can be adjusted through adjustment of the relative position of the upper middle column and the lower middle column. When any one hand screw is screwed off, the upper middle column and the fan blades can rotate to be in a state that the fan blades are downward by using the other hand screw as a shaft, and therefore the purposes that the electric fan is folded, and the occupied space is reduced are achieved.
Description
Technical field
The present invention relates to a kind of daily household electrical appliances, particularly relate to a kind of electric fan of Liftable foldable.

In the prior art, electric fan is that one utilizes motoring flabellum to rotate, and reaches the household electric appliance making air accelerate circulation, is mainly used in cooling and heatstroke-eliminating and ventilating air.Electric fan kind is a lot, and wherein domestic electric fan just has ceiling fan, desk fan, stand fan, rotary blade fan etc.In order to obtain suitable blowing angle, stand fan and rotary blade fan generally arrange the adjustable for height function of electric fan, in the prior art, can regulate electric fan height devices all complex structures, and long-time use is easily damaged.
Summary of the invention
In view of this, the present invention proposes a kind of electric fan of Liftable foldable, to solve the complicated perishable problem of above-mentioned electric fan height-adjusting device.
For achieving the above object, technological scheme of the present invention is achieved in that
An electric fan for Liftable foldable, comprises base, center pillar and flabellum, and described center pillar is divided into center pillar and lower center pillar, has an elongated hole on before described upper center pillar, has two tapped holes on before described lower center pillar; Described upper center pillar is connected by two hand screws with described lower center pillar, by regulating the height of the relative position of upper center pillar and lower center pillar and adjustable described Liftable foldable electric fan, screw off arbitrary described hand screw, namely described upper center pillar and described flabellum can hand screw described in another be that axle rotates to flabellum towards upper/lower positions, thus reach folding electric fan, reduce the object taken up space.
The electric fan of above-described a kind of Liftable foldable, wherein, the two ends of described elongated hole are semicircle, and be rectangular in the middle part of described elongated hole, described semicircular diameter is identical with width in the middle part of described elongated hole.
The electric fan of above-described a kind of Liftable foldable, wherein, the width of described elongated hole is less than the external diameter that described hand twists the pad of bolt.
The electric fan of above-described a kind of Liftable foldable, wherein, described elongated hole is positioned at described upper center pillar lower end.
The electric fan of above-described a kind of Liftable foldable, wherein, two tapped holes of described lower center pillar are positioned at the upper end of described lower center pillar, and described in two, tapped hole is arranged above and below.
The electric fan of above-described a kind of Liftable foldable, wherein, the length of described lower center pillar is greater than the length of described lower center pillar, and the length difference of described lower center pillar and described upper center pillar is greater than the radius of described flabellum.
The present invention is owing to have employed above-mentioned technology, and the good effect of generation is:
(1) by the use of the electric fan of a kind of Liftable foldable of the present invention, simple structure can be utilized to reach the object of electric fan blowing lift in height.
(2) used by the use of the electric fan of a kind of Liftable foldable of the present invention, the storage space of electric fan can be made greatly to reduce.
Accompanying drawing explanation
The accompanying drawing forming a part of the present invention is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
