Abstract
The invention discloses a silent fan. The silent fan comprises a body frame, wherein the body frame is fixedly connected with a motor; fan blades are rotatably connected with the motor; a group of tooth-shaped grooves are uniformly distributed in the edge of the body of the motor; a group of gaps are respectively formed in each vane of the fan blades; the tooth-shaped grooves are distributed symmetrically by taking the rotating shaft of the motor as a centre; two gaps are formed in each vane of the fan blades. According to the silent fan disclosed by the invention, the gaps and the tooth-shaped grooves which can absorb useless vibration are formed in the vanes of the fan blades and the body of the motor, so that the noises of the fan are greatly reduced.
Description
Technical field
The present invention relates to a kind of fan, or rather, is a kind of quiet fan.
Background technique
Fan, claims again electric fan, thereby refers to a kind of device that drives flabellum rotation generation wind-force by motor.Along with scientific and technological development, the use of fan has been not only people and animals' reducing temperature of heatstroke prevention, on some machinery, electronic equipment, comes equipment cooling by installing fan additional.
In the using process of fan, it is found that often noise is larger for the equipment that has fan cooling cooling, flabellum can produce noise because produce useless additional vibratory in manufacturing wind-force, affects the working life of flabellum, and people's life is caused to puzzlement.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby a kind of quiet fan that can effectively reduce noise is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of quiet fan, comprise a body frame, in described body frame, be fixedly connected with a motor, on described motor, connect rotationally flabellum, the body edges of described motor is uniformly distributed one group of profile of tooth groove, is respectively provided with one group of gap on the blade of described flabellum.
As preferred embodiment of the present invention, the distribution that is centrosymmetric centered by the rotating shaft of described motor of described profile of tooth groove.
As preferred embodiment of the present invention, the quantity of the described gap on each blade of described flabellum is 2.
Because quiet fan of the present invention is provided with gap and the profile of tooth groove that can absorb useless vibration on the blade of flabellum and on the body of motor, thereby greatly reduce the noise of fan.
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the perspective view of quiet fan of the present invention;
Fig. 2 is the perspective view of the quiet fan in Fig. 1, is now another visual angle.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
The invention provides a kind of quiet fan that can effectively reduce noise.
As shown in Figure 1 and Figure 2, a kind of quiet fan 1, comprise a body frame 21, in described body frame 21, be fixedly connected with a motor 22, on described motor 22, connect rotationally flabellum 23, the body edges of described motor 22 is uniformly distributed one group of profile of tooth groove 4, is respectively provided with one group of gap 3 on the blade of described flabellum 23.
As shown in Figure 1, described profile of tooth groove 4 distribution that is centrosymmetric centered by the rotating shaft of described motor 22.
As shown in Figure 1 and Figure 2, the quantity of the described gap 3 on each blade of described flabellum 23 is 2.
The quiet fan of this invention is provided with gap and the profile of tooth groove that can absorb useless vibration on the blade of flabellum and on the body of motor, thereby greatly reduces the noise of fan.
Below only with a mode of execution, mentality of designing of the present invention is described, in the situation that system allows, the present invention can expand to external more function module simultaneously, thereby expands to greatest extent its function.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
Claims (3)
1. a quiet fan (1), comprise a body frame (21), it is characterized in that, in described body frame (21), be fixedly connected with a motor (22), on described motor (22), connect rotationally flabellum (23), the body edges of described motor (22) is uniformly distributed one group of profile of tooth groove (4), on the blade of described flabellum (23), is respectively provided with one group of gap (3).
2. quiet fan according to claim 1, is characterized in that, the distribution that is centrosymmetric centered by the rotating shaft of described motor (22) of described profile of tooth groove (4).
3. quiet fan according to claim 2, is characterized in that, the quantity of the described gap (3) on each blade of described flabellum (23) is 2.
