Description

DC fan wind speed control device

In this case, a DC fan wind speed control device can be used to adjust the fan speed of the DC fan by allowing the hand or the radio to be connected to the network module.

The traditional Republic of China patent M546654, which is a DC fan wind speed control device, allows the hand or radio interface to adjust the fan speed of the DC fan, but the DC to DC converter is expensive and needs to be replaced by cheaper parts.

The average consumer uses a DC fan to control the DC fan at a high fan speed to provide a large air volume, but in the middle of the night, the DC fan is controlled at a fixed minimum fan speed, resulting in low noise, long-term use, and a mute effect.

In general, when the air quality is not good, the DC fan in the air cleaner will control the high fan speed to generate a large amount of clean air. Since the DC fan will generate high noise when the fan speed is high, it will be used after a short period of time. When the air quality is good, it will be adjusted to a low fan speed, resulting in low noise, long-term use, and will be turned off once in the middle of the night.

In the second embodiment of the present invention, a DC fan wind speed control device is provided, which comprises: a power switch, a mechanical switch, a relay or a semiconductor switch, which is connected by a button, a controller or a radio. Group control; an adjustable voltage regulator that can adjust the output voltage, which is controlled by a button, a controller or a radio network module; and a diode, the diode is used for a series adjustable regulator Connect the rear diode and the adjustable regulator together with the power switch.

Some embodiments embodying the features and advantages of the present invention are described in detail in the following description. It should be understood that the present invention can be varied in different aspects without departing from the scope of the present invention, and the description and drawings are for illustrative purposes, and are not structurally limiting.

In the first aspect, please refer to FIG. 1 , FIG. 2 and FIG. 3 . FIG. 1 is a system diagram of a button control DC fan wind speed control device, and FIG. 2 is a system diagram of a controller controlling a DC fan wind speed control device. 3 is a system diagram of a DC fan wind speed control device for controlling the radio network connection module. It can be seen from Fig. 1, Fig. 2 and Fig. 3 that an AC to DC power supply 12 outputs 5V; the constant flow fan wind speed control device 10, comprising: a power switch 103, which is controlled by a button 104, a controller 105 or a radio network module 106; a diode 102, the diode 102 is used to connect the power switch 103; The switch 103 is turned on, and the current is output through the power switch 103, which generates a 5V output, and drives the DC fan 11 to generate a maximum fan speed; once the power switch 103 is not turned on, current is output through the diode 102, since the diode 102 has 0.7V. The voltage drop, therefore 4.3V, is used to drive the DC fan 11 to produce a minimum fan speed.

In another aspect, please refer to FIG. 4, FIG. 5 and FIG. 6. FIG. 4 is a system diagram of another button control DC fan wind speed control device, and FIG. 5 is another controller control DC fan wind speed control. The system diagram of the device, Fig. 6 is a system diagram for controlling the wind speed control device of the DC fan of another radio network module.
