Abstract
The invention discloses a silencing fan with two fan blades. The fan comprises a driving motor, and a first fan blade arranged on a rotating shaft of the driving motor, wherein a second fan blade which has the same size as the first fan blade is arranged on the rotating shaft and fixed on a shaft sleeve; the shaft sleeve is sleeved outside the rotating shaft and not contacted with the rotating shaft; the shaft sleeve and the rotating shaft rotate at the same speed in opposite directions; and the installation direction of the second fan blade is opposite to that of the first fan blade. According to the silencing fan with the two fan blades, the two fan blades rotate in opposite directions, and noise generated when the two fan blades work is mutually interfered and offset, so that a silencing effect is achieved; and meanwhile, the first fan blade and the second fan blade are oppositely arranged, and do work and blow air in the same direction when rotating in opposite directions, so that the air pressure and air quantity of the output end can be increased, and suction is increased at the input end of the fan.
Description
Technical field
The present invention relates to the noise reduction fan of a kind of fan, particularly a kind of biparting leaf.
Background technique
At present, fan is the household electric appliance that frequently touch in people's daily life, and fan can directly apply to and be that people blowing, fan can also be applied on the sink of computer or on the extraction fan of range hood.But more existing fans are because power is bigger, and like the extraction fan on the range hood, noise is bigger during work, influences people's life.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the present invention is to provide a kind of fan of high-power low noise.
The technological scheme that the present invention adopted mainly is:
A kind of noise reduction fan of biparting leaf; Comprise drive motor, be installed in first flabellum in the rotating shaft of drive motor; Said rotating shaft is provided with and equal-sized second flabellum of first flabellum, and said second flabellum is fixed on the axle sleeve, and said axle sleeve is socketed in outside the rotating shaft and with rotating shaft and does not contact; The rotating speed equidirectional of said axle sleeve and rotating shaft is opposite, and the installation direction of said second flabellum is opposite with first flabellum.
As the further improvement of technique scheme, said axle sleeve is preferably through second drive motor drives; The driving mode of axle sleeve is not limited to adopt motor driving, and said axle sleeve can also be driven by rotating shaft through the gear transmission group; Perhaps be connected rotating shaft with the transmission leather strap, drive by rotating shaft through drive wheel.
As the further improvement of technique scheme, said first flabellum and second flabellum can be axial flow or centrifugal, and the setting angle of said first flabellum and second flabellum is opposite fully.
The invention has the beneficial effects as follows: the noise reduction fan of this biparting leaf is owing to two flabellum backward rotation, and the noise that produces during two flabellums work interferes with each other, and cancels each other, and plays the effect of noise reduction; Because first flabellum and the antipodal relation of the second flabellum setting angle during both backward rotation, are to same direction acting blowing, can increase the blast and the air quantity of output terminal, and promote suction simultaneously at the fan input end.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
Fig. 1 is a structural representation of the present invention.
Embodiment
With reference to Fig. 1, the noise reduction fan of a kind of biparting leaf provided by the invention comprises drive motor 5, and first flabellum 2 is installed in the rotating shaft 1 of drive motor 5, and said first flabellum 2 is by drive motor 5 driven rotary; Rotating shaft 1 is provided with first flabellum, 2 equal-sized second flabellum, 3, the first flabellums 2 and second flabellum 3 and can be axial flow or centrifugal, and the setting angle of first flabellum 2 and second flabellum 3 is opposite fully; Second flabellum 3 is fixed on the axle sleeve 4, and said axle sleeve 4 is socketed in outside the rotating shaft 1 and with rotating shaft 1 and does not contact, and is preferred; Axle sleeve 4 connects second drive motor; And by the motor driving rotation, the rotating speed of axle sleeve 4 is identical with the rotating speed of rotating shaft 1, the direction of rotation of axle sleeve 4 sense of rotation and rotating shaft 1.In addition, axle sleeve 4 can also connect rotating shaft 1 through driving mechanism, and drives rotation by rotating shaft 1, and said driving mechanism can be the gear transmission group, and driving mechanism can also be made up of drive wheel and transmission leather strap.
The noise reduction fan of this biparting leaf is owing to two flabellum 2,3 backward rotation, and the noise that produces during two flabellums work interferes with each other, and cancels each other, and plays the effect of noise reduction; Because the relation of first flabellum 2 and second flabellum, 3 anti-dresses during both backward rotation, is to same direction acting blowing, can increases the blast and the air quantity of output terminal, and promote suction simultaneously at the fan input end.
The above is merely preferential mode of execution of the present invention, as long as realize that with basic identical means the technological scheme of the object of the invention all belongs within protection scope of the present invention.
