What is the working principle of the suction blower?
The principle of suction can also fan example, the blade side of the compressed air, the back of the air density is reduced, the need to add air to restore the original balance
And because the blade is rigid, the partially compressed air can only move away from the direction of the blade, so that the air is moved to form the effect of blowing
Take the fan as an example: observe the fan blade, the blade has an angle. When the blade is rotated, the air is cut, and the side of the blade is expelled from the air, resulting in an increase in the local pressure of the air, an increase in the air density (the power to automatically return to normal pressure)
The principle of suction and hair is the same, are the category of fluid mechanics.
And because the leaf block, can not get the air from the front, only from the rear of the blade to get the air, if the blade made of cylindrical tube, the air on the directional movement, and produce the effect of suction.
