Abstract

The utility model relates to an internal rotation type low-noise fan which comprises a fan hood. A first motor is longitudinally arranged at the upper end of the fan hood, a motor bin is arranged in the fan hood, an electric fan body matched with the motor bin is fixedly connected to the inside of the motor bin, a transmission shaft at the lower end of the first motor penetrates through the upper wall of the fan hood from top to bottom to be fixedly connected with the upper wall of the motor bin, a gap is formed between the lower surface of the motor bin and the inner wall of the fan hood, a control device for controlling the first motor is fixedly connected to the outer surface of the fan hood, and a timing switch, a time delay switch, a microprocessor and a power device are arranged in the control device, wherein the timing switch and the time delay switch are electrically connected with the first motor, the microprocessor is electrically connected with the electric fan body, the power device is used for supplying power for the microprocessor, the timing switch and the time delay switch, and the time delay switch is electrically connected with the microprocessor. According to the internal rotation type low-noise fan, changing of the position of the internal electric fan body is automatically controlled by the control device, so that noise of the fan in the daytime and at night is changed, and the intelligent noise reduction ability of the fan is improved.

Description

Internal rotation type low-noise fan
Technical field
The utility model relates to a kind of internal rotation type low-noise fan.
Background technique
Low-noise fan in the market adopts the mode of passive noise reduction to reduce the noise of fan mostly, the noise of fan is mainly reflected in the sound that sound of the wind, motor sound and resonance produce, because current fan is fixed structure mostly, cannot initiatively reduce noise by changing position of fan according to the variation of time, very not intelligent.
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 internal rotation type low-noise fan, solve the problem that common low-noise fan cannot intelligent active noise reduction.
The utility model solves the technological scheme that its technical problem adopts: a kind of internal rotation type low-noise fan, comprise hood, hood upper end is vertically arranged with the first motor, hood inside is provided with motor room, in motor room, be fixedly connected with the electric fan matching with motor room, the first motor lower end transmission shaft is fixedly connected with motor room upper wall through hood upper wall from top to bottom, between motor room lower surface and hood inwall, there is gap, hood outer surface is fixedly connected with and is useful on the control gear of controlling the first motor, in control gear, be provided with the time switch being electrically connected with the first motor, delay switch, the microprocessor being electrically connected with electric fan and for give microprocessor, the power supply unit of time switch and delay switch power supply, delay switch is electrically connected with microprocessor.
Further, for convenient rotation, electric fan length is less than hood inner diameter length.
Further, for more quiet, on hood inwall, be provided with Sound-proof material.
Further, for more quiet, the first motor is wrapped with puigging.
The beneficial effects of the utility model are that internal rotation type low-noise fan of the present utility model is automatically controlled fan by control gear and changed the position of inner electric fan according to the time, thereby changes the noise of fan round the clock, promotes the Intelligent noise reduction ability of fan.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is front view of the present utility model.
1. hoods in figure, 2. the first motor, 3. motor room, 4. electric fan, 5. control gear.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of internal rotation type low-noise fan as depicted in figs. 1 and 2, comprise hood 1, hood 1 upper end is vertically arranged with the first motor 2, hood 1 inside is provided with motor room 3, in motor room 3, be fixedly connected with the electric fan 4 matching with motor room 3, the first motor 2 lower end transmission shafts are fixedly connected with motor room 3 upper walls through hood 1 upper wall from top to bottom, between motor room 3 lower surfaces and hood 1 inwall, there is gap, hood 1 outer surface is fixedly connected with and is useful on the control gear 5 of controlling the first motor 2, in control gear 5, be provided with the time switch being electrically connected with the first motor 2, delay switch, the microprocessor being electrically connected with electric fan 4 and for give microprocessor, the power supply unit of time switch and delay switch power supply, delay switch is electrically connected with microprocessor, the first motor 2 according to time switch be controlled at 6:00 AM and evening 10 automatic operations, time switch is controlled delay switch simultaneously and is started working, after delay switch control the first motor 2 rotating shaft Rotate 180s °, automatically close, and time switch sends signal to microprocessor simultaneously, microprocessor control electric fan quits work, in the time that cutting out the first motor 2, delay switch sends signal to microprocessor, microprocessor starts counterrotating according to the SC sigmal control electric fan 4 of delay switch, thereby realize, the flabellum of electric fan 4 is rotated near outside daytime, rotate to the function of internal work night.
Further, for convenient rotation, electric fan 4 length are less than hood 1 inner diameter length, further, for more quiet, on hood 1 inwall, be provided with Sound-proof material, further, for more quiet, the first motor 2 is wrapped with puigging, internal rotation type low-noise fan of the present utility model is automatically controlled fan by control gear 5 and is changed the position of inner electric fan 4 according to the time, thereby changes the noise of fan round the clock, promotes the Intelligent noise reduction ability of fan.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this model utility technological thought, carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to claim scope.
