The utility model relates to a self-adjusting low-noise fan which comprises a shell. An electric fan is arranged inside the shell and is fixedly connected with the shell through a connecting bracket, a sound insulation layer is fixedly connected to the inner wall of the shell, a first sound sensor is fixedly connected to the inner wall of the shell, a control unit is fixedly connected to the outer wall of the shell, a microprocessor electrically connected with the signal output end of the first sound sensor and an electric-control switch electrically connected with the signal output end of the microprocessor are arranged inside the control device, a second sound sensor used for detecting exterior noises of the shell is fixedly connected to the upper surface of the control device, and the second sound sensor is electrically connected with the microprocessor arranged in the control device. Reduction of rotating speed can be automatically controlled according to different time through the control device, so that service life of the fan can be greatly prolonged, the noises at night can be reduced, and energy conservation can be achieved.
Description
Technical field
The utility model relates to a kind of self-regulation low-noise fan.
Background technique
Existing low-noise fan is simple in structure, by passive noise reduction and low noise motor, to reduce the noise of blower fan mostly, but common low-noise fan cannot further reduce noise according to the variation of time by changing the rotating speed of blower fan automatically, if round-the-clock all the period of time all adopts High Rotation Speed not only to affect working life of blower fan, nor energy-conserving and environment-protective.
Model utility content
The technical problems to be solved in the utility model is: for solving the problem of above-mentioned existence, provide a kind of self-regulation low-noise fan, solving common blower fan cannot carry out the problem of energy-saving and noise-reducing along with time self-regulating rotary speed.
The utility model solves the technological scheme that its technical problem adopts: a kind of self-regulation low-noise fan, comprise housing, in housing, be provided with electric fan, between electric fan and housing, by connection bracket, be fixedly connected with, inner walls is fixedly connected with puigging, in inner walls, be fixedly connected with first sound sound sensor, on housing outer wall, be fixedly connected with control gear, in control gear, be provided with the microprocessor being electrically connected to first sound sound sensor signal output part and the electrically switchable grating being electrically connected to microprocessor signals output terminal, control gear upper surface is fixedly connected with the second sound sound sensor for detection of housing appearance noise, second sound sound sensor is electrically connected to the microprocessor in control gear.
Further, for electric energy is provided, in control gear, be provided with for the power supply unit to control gear power supply.
Further, for electric energy is provided, electric fan is powered by ABAP Adapter.
Further, for noise reduction, between control gear and housing, be provided with buffer layer.
The beneficial effects of the utility model are that self-regulation low-noise fan of the present utility model is automatically controlled blower fan by control gear according to the difference of time and reduced rotating speed, not only greatly extends the working life of blower fan, reduces noise at night, and more energy-conservation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
