Abstract
The invention discloses a kind of Portable small fans comprising bottom case, the bottom wall of bottom case are equipped with air inlet hole, the motor equipped with fan blade component and driving fan blade rotation in bottom case, and the blade part of fan blade component stretches out bottom case, and bottom case front end is also connected with upper cover；The bottom case is cylinder, and the outer wall of bottom case front end is equipped with card slot, and the upper cover is cylindrical shape, and the inner wall of upper cover is equipped with the sliding block cooperated with card slot.In the use of the present invention, sliding upper cover moves down, blade part is made to stretch out upper cover, at this time when opening the switch, motor drives fan blade component work, and when not in use, sliding upper cover moves up, and upper cover wraps up blade.Structure is very simple, and cost is very low, small in size, is convenient for carrying, easy to use, can effectively protect blade when not in use.
Description
[technical field]
The present invention relates to a kind of Portable small fans.
[background technique]
With the first improvement of people's living standards, people like taking a kind of portable when travelling outdoors in hot weather
Small fan.Portable small fan can bring wind, play the role of for people's cooling very big.
Existing portable small fan some have USB interface, can be directly inserted on mobile power source can use it is non-
It is often convenient；Some can be automatically turned on as the power supply of included charging.But when not in use not regardless of which kind of portable small fan
Facilitate collection, it is easy to deform blade damage.
[summary of the invention]
It is an object of the invention to provide in place of overcome the deficiencies in the prior art, a kind of structure is very simple, and cost is very
It is low, it is small in size, it is convenient for carrying, it is easy to use, it can effectively protect the Portable small fan of blade when not in use.
The object of the present invention is achieved like this:
A kind of Portable small fan, it is characterised in that it includes bottom case 1, and the bottom wall 11 of bottom case 1 is equipped with air inlet hole 12, bottom case
Equipped with fan blade component 2 and the motors 3 of fan blade rotation are driven in 11, and the blade 21 of fan blade component 2 partly stretches out bottom case 1, before bottom case 1
End is also connected with upper cover 4；The bottom case 1 is cylinder, and the outer wall 13 of 1 front end of bottom case is equipped with card slot 14, the upper cover 4
For cylindrical shape, the inner wall of upper cover 4 is equipped with the sliding block 41 cooperated with card slot 14.
A kind of Portable small fan as described above, it is characterised in that closure 141 He of detent is equipped in the card slot 14
Open detent 142.
The beneficial effects of the present invention are:
In the use of the present invention, sliding upper cover moves down, blade part is made to stretch out upper cover, at this time when the opening switch
When, motor drives fan blade component work, and when not in use, sliding upper cover moves up, and upper cover wraps up blade.Structure is non-
Often simple, cost is very low, small in size, is convenient for carrying, easy to use, can effectively protect blade when not in use.
[Detailed description of the invention]
Fig. 1 is structure chart of the invention.
[specific embodiment]
The present invention will be further explained below with reference to the attached drawings:
A kind of Portable small fan, it is characterised in that it includes bottom case 1, and the bottom wall 11 of bottom case 1 is equipped with air inlet hole 12, bottom case
Equipped with fan blade component 2 and the motor 3 of fan blade rotation is driven in 1, and the blade 21 of fan blade component 2 partly stretches out bottom case 1, before bottom case 1
End is also connected with upper cover 4, and bottom case 1 is equipped with switch (not shown), and the bottom case 1 is cylinder, 1 front end of bottom case
Outer wall 13 is equipped with card slot 14, and the upper cover 4 is cylindrical shape, and the inner wall of upper cover 4 is equipped with the sliding block 41 cooperated with card slot 14.The present invention
When in use, sliding upper cover 4 moves down, and blade 21 is made partly to stretch out upper cover 4, and at this time when opening the switch, motor 5 is driven
Fan blade component work, when not in use, sliding upper cover move up, and upper cover 4 wraps up blade 21.Structure is very simple,
Cost is very low, small in size, is convenient for carrying, easy to use, can effectively protect blade when not in use.
To make upper cover conveniently be fixed on the position opened or closed after sliding, closure detent 141 is equipped in card slot 14
With opening detent 142.
