Abstract
The utility model belongs to the field of a household appliance manufacturing technology and particularly relates to a fan. The fan comprises a shell (1), a protective net (2) arranged at the front end of the shell (1), a supporting plate (3) arranged at the rear end of the shell (1) and a base (4), wherein the supporting plate (3) is provided with a fan (5); and fan blades (6) stretching into the shell (1) are mounted on a rotary shaft of the fan (5). The fan is characterized in that airflow through holes (7) are arranged on the side wall of the shell (1); a first airflow through hole (70) is arranged at the rear end part of the shell (1); and a second airflow through hole (71) is arranged at the front end part of the shell (1). The fan adopting the structure has smaller noises and can effectively improve the wind quantity.
Description
Technical field
The utility model belongs to living electric apparatus manufacturing technology field, is specifically related to a kind of fan.
Background technique
Existing placement on the table desk-top small fan or the fan of similar structure, usually mainly formed by shell, the protecting wire net that is installed in the shell front end, the dunnage that is installed in outer casing back and base, be provided with blower fan in dunnage, the fan blade that stretches in the shell is installed in the rotating shaft of blower fan.Adopt the fan of this structure, owing to require rotating speed of motor higher, windage is big, so in the using process, noise is big especially.
The model utility content
The purpose of this utility model is to provide a kind of noise less, and can effectively improve the fan of air quantity.
The purpose of this utility model is achieved in that a kind of fan, comprise shell (1), be installed in the protecting wire net (2) of shell (1) front end, the dunnage (3) that is installed in shell (1) rear end and base (4), be provided with blower fan (5) in dunnage (3), the fan blade (6) that stretches in the shell (1) is installed in the rotating shaft of blower fan (5), it is characterized in that the sidewall of described shell (1) is provided with air-flow through hole (7).
The rearward end of described shell (1) is provided with the first air-flow through hole (70).
The front end of described shell (1) is provided with the second air-flow through hole (71).
The rearward end of described shell (1) is provided with the first air-flow through hole (70), and the front end of shell (1) is provided with the second air-flow through hole (71).
The middle part of described shell (1) is provided with also the 3rd air-flow through hole (72).
Described air-flow through hole (7) is square opening.
Described air-flow through hole (7) is circular port.
Good effect of the present utility model: owing to be provided with the air-flow through hole at the sidewall of shell, such as front end and/rearward end and/middle part arranges air-flow to be passed through, and can effectively reduce gas-flow resistance, thereby improve air quantity and reduce noise.
