In the embodiment of the invention, the 220V voltage stabilizing circuit and the 110V voltage stabilizing circuit have simpler circuit structures, and the two circuits have similar overall structures and lower overall cost although the size values of the elements of the two circuits are different.
The embodiment of the invention also provides a vacuum pump, which comprises a vacuum pump body and a full-voltage controller for supplying power to the vacuum pump body, wherein the voltage display module is used for detecting the output voltage of the full-voltage controller and is provided with an LED screen for displaying the voltage, and a user displays the detected output voltage according to the voltage display module, when the output voltage is close to 110V, namely between 90V and 160V, the output voltage is adjusted to 110V by adjusting an adjusting switch corresponding to the variable resistor VR 1; when the output voltage is close to 220V, namely between 160V and 240V, the output voltage is regulated to 220V by regulating the regulating switch corresponding to the variable resistor VR 1. Although the voltage is manually regulated and stabilized by adopting the regulating switches corresponding to the variable resistors VR1 and VR2, the operation is complex, but the applicable voltage range is large, and the voltage regulator is particularly applicable to rural areas or third world countries with unstable voltage.
And because the system can automatically select the corresponding voltage stabilizing circuit to regulate voltage, for example, when the output voltage is 110V, the corresponding regulating switch of the 220V voltage stabilizing circuit can not react, so that the worry that the output voltage is excessively regulated is avoided.
Although the present invention has been described in terms of the preferred embodiments, it is not intended to be limited to the embodiments, and any person skilled in the art can make any possible variations and modifications to the technical solution of the present invention by using the methods and technical matters disclosed above without departing from the spirit and scope of the present invention, so any simple modifications, equivalent variations and modifications to the embodiments described above according to the technical matters of the present invention belong to the technical solution of the present invention.
