The portable fan belongs to mini small electric fan, which can be placed on a table, winded on a bed pillar, held in hands and various utilization modes, the portable fan is very flexible, which can be charged by a power supply, and is convenient for carrying out.
Description
Technical field
The utility model relates to a kind of electric fan.
Background technique
Electric fan is in order to solve the commodity of summer weather sweltering heat, for many years, what electric fan was mainly considered is its function, satisfy the demand of people's needs reducing temperature of heatstroke prevention, be to consider strong wind power in the design, air quantity is big, therefore, electric fan mostly be body big, move inconvenience, ignored people to dexterous, practical, easy to carry pursuit.
The model utility content
Problem to be solved in the utility model provides a kind of small and exquisite, portable electric fan of carrying conveniently moving.
The utility model solves the problems referred to above by the following technical solutions: a kind of portable electric fan, comprise motor, supporting frame, supporting frame be can be arbitrarily crooked tubular structure, the supporting frame upper end is equipped with motor, the output terminal of motor is connected with collapsible blade mechanism together.
Described blade mechanism comprises newel, and the newel concentric fits is on motor output shaft, and the newel rear portion also is rotatably connected to a plurality of blades, is provided with the spring mechanism that makes vanes retract and extension between blade and the newel.
Described spring mechanism comprises and is sleeved on the newel and the end is fixed on the extension spring of newel front portion, extension spring is set with position-limiting tube outward, the position-limiting tube front end is fixed on the newel front portion, the other end opening, extension spring is connected with a plurality of little springs at the position-limiting tube opening, and the little spring the other end is connected in each blade bottom.
Be provided with buckle on blade, corresponding position-limiting tube is provided with draw-in groove, and buckle is pressed into draw-in groove and promptly blocks.
End at supporting frame is provided with power sector, is provided with connecting line in the tubular structure of supporting frame, and connecting line connects power sector and motor.
Described power sector is a rechargable power supplies.
Described power sector is the Ac connecting line.
Supporting frame is made by the metal calibration tube.
Described metal calibration tube is a metal bellows.
The blade mechanism of the utility model setting is collapsible structure, supporting frame also be can be arbitrarily crooked tubular structure, when electric fan does not use, blade mechanism can be shunk, supporting frame is folded, and reduces the volume of electric fan, and is easy to carry, conveniently moving.The flexible spring mechanism that utilizes of blade mechanism is finished, described spring mechanism main body is extension spring, extension spring is sleeved on the newel, extension spring is set with position-limiting tube outward, position-limiting tube one end is fixedlyed connected with the newel front portion, the other end opening, extension spring is connected with a plurality of little springs at the position-limiting tube opening, and the other end of little spring is connected on each blade, when spring is in relaxed state, blade is open, both can use after the energising, with blade when newel shrinks, because the position-limiting action of position-limiting tube, extension spring and little spring all are stretched, tip the buckle on the blade on the position-limiting tube draw-in groove, blade promptly is retracted, and buckle draws back, extension spring and little spring retraction, blade is opened.Supporting frame is made by the metal calibration tube, can crookedly arbitrarily as required also finalize the design, the utility model belongs to miniature little electric fan, can be placed on the desk, coil on the column, take in the hand or the like usage mode, very flexible, and the utility model can use charge power supply, is convenient for carrying and goes out.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
