Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, embodiment 1: a hair drier circuit using a low-voltage DC brushless motor comprises a motor MOT, a resistor R1, a rectifier DB1, a diode D1, a capacitor C1 and a low-voltage DC brushless motor driving circuit, wherein the resistor R1 is originally connected with an AC live wire, the other end of the resistor R1 is connected with one input end of a rectifier DB1, the other input end of the rectifier DB1 is connected with an AC zero wire, the output end of the rectifier DB1 + is connected with the cathode of a diode D1, the capacitor C1 and one input end of the low-voltage DC brushless motor driving circuit, the anode of a diode D1 is connected with the other end of the capacitor C1, the output end of the rectifier DB1 and the other input end of the low-voltage DC brushless motor driving circuit, and the output end of the low-voltage DC brushless motor driving circuit is connected.
The resistor R1 is a heating resistance wire. Diode D1 is a TVS diode. The capacitor C1 is a filter capacitor.
The working principle is as follows: the 220V AC power supply is firstly reduced in voltage through a heating resistance wire R1, then rectified through a bridge stack DB1, rectified into direct current and filtered through a capacitor C1. TVS pipe D1 clamps the power, prevents that the voltage is too high to damage the drive circuit of the following low voltage DC brushless motor. The low-voltage DC brushless motor driving circuit drives the low-voltage DC brushless motor at the rear end. At the moment of switching on the 220V AC power supply, because the DC brushless motor is not started, the current consumed by the driving circuit is very small, the impedance is relatively large, the voltage division of the heating resistance wire R1 is relatively large, the voltage on the low-voltage DC brushless motor driving circuit can exceed the working voltage of the driving circuit to cause circuit damage, and the TVS tube D1 plays a clamping role and clamps the voltage within the normal working voltage of the low-voltage DC brushless motor driving circuit.
In embodiment 2, based on embodiment 1, the model of the rectifier DB1 is MB10S, and may be another rectifier module or chip of the same type.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
