Abstract
The utility model relates to the technical field of fans, in particular to an improved small fan which comprises a shell. A circuit board is arranged in the shell, one end of the circuit board is connected with a motor, an output end of the motor is connected with fan blades, power supply equipment is connected to the other end of the circuit board, an air inlet is arranged on a side surface, which corresponds to the rear end of the motor, of the shell, and air outlets are arranged on a side surface, which corresponds to the fan, of the shell. The motor and the fan blades are arranged inside the shell, so that the improved small fan is convenient to use and is safe. In addition, airflow can be guided into the shell via the air inlet and exhausted via the air outlets, so that fixed circulation channels for the air are formed in the shell, and noise generated when the motor and the fan blade rotate is low.
Description
Technical field
The utility model relates to the fan technical field, particularly a kind of improved small fan.
Background technique
People are often vexed for high temperature and heating summer in summer, influence people's mood, if a kind of small fan can be arranged, can carry, constantly bring to people refrigerant and comfortable, the inconvenience that the sweltering heat of effectively alleviating summer is brought.
But the fan of the type is external with flabellum in the existing technology, does not have shield, in the running, is easy to generate scratching, and human body is caused unnecessary damages, and flabellum is caused damage, so use inconvenient.
Summary of the invention
The purpose of the utility model is the deficiency to existing technology, a kind of convenient use and safety is provided, the improved small fan that noise is little.
For realizing above-mentioned purpose, the utility model adopts following technological scheme: a kind of improved small fan comprises shell; Be provided with circuit board in the said shell; One end of said circuit board is connected with motor, and said motor output end is connected with flabellum, and the other end of said circuit board is connected with power supply unit; Said shell offers intake grill corresponding to the side of said motor rear end, and said shell is provided with exhaust outlet corresponding to the side of said flabellum.
Wherein, said intake grill is located at the rear side of said shell.
Wherein, said exhaust outlet is located at the front side and/or the upper end of said shell.
Wherein, said power supply unit comprises battery box, is located at lithium cell in the said battery box and the battery case lid that is used with said battery box.
Wherein, a side of said shell is provided with switch, states switch and is electrically connected with said circuit board.
Wherein, the opposite side of said shell offers charging inlet, and said charging inlet is electrically connected with said circuit board.
The utility model beneficial effect is: the utility model comprises shell, is provided with circuit board in the said shell, and an end of said circuit board is connected with motor; Said motor output end is connected with flabellum, and the other end of said circuit board is connected with power supply unit, and said shell offers intake grill corresponding to the side of said motor rear end; Said shell is provided with exhaust outlet corresponding to the side of said flabellum, through motor and flabellum is built-in, and convenient the use and safety; And the built-in air-flow that makes of flabellum is introduced from intake grill; Discharge from exhaust outlet again, make wind have fixing circulation passage in the enclosure, can make the noise that produces in the process of motor and flabellum rotation little like this.
