Adjustable electronic transformer for heating mat

Abstract

The invention discloses an adjustable electronic transformer for a heating mat, and aims to solve the problems of incapability of adjusting the power of the heating mat and high energy consumption. The adjustable electronic transformer for the heating mat comprises an upper power supply box, a lower power supply box, an adjustable electronic transformer circuit, an adjustment knob, an AC (Alternating Current) cable, a DC (Direct Current) cable, a plug and a power supply output head, wherein the adjustable electronic transformer circuit comprises a rectifying circuit, an adjustment circuit, a high-frequency oscillating circuit and an output transformer; the adjustment circuit consists of a resistor R2, a potentiometer R3 and a capacitor C5. By adopting the adjustable electronic transformer for the heating mat provided by the invention, energy is saved, the product comfort is enhanced, and the service life of a product is prolonged.

Description

technical field [0001] The invention relates to the field of transformers, in particular to an adjustable electronic transformer for heating pads with reduced losses. Background technique [0002] An electronic transformer is actually a type of inverter. First, the alternating current is changed into a pulsed direct current, and then an oscillator is composed of electronic components to change the pulsed direct current into a high-frequency current. After outputting the required voltage through the switching transformer, it can be used by electrical appliances. In the prior art, the 60-70w electronic transformer for heating pad is composed of a rectifier circuit, a high-frequency oscillation circuit and an output transformer, which cannot be adjusted when the product load is constant, so that the transformer still uses the output transformer under different temperature environments. Constant power, so the user can't feel the constant temperature, and the comfort level is n...

Problems solved by technology

In the prior art, the 60-70w electronic transformer for heating pad is composed of a rectifier circuit, a high-frequency oscillation circuit and an output transformer, which cannot be adjusted when the product load is constant, so that the transformer still uses the output transformer under different temperature environments. Constant power, so the user can not feel the constant temperature, the comfort level is not good, in addition, when the temperature is high but the heating pad must be used, it will not only cause discomfort, but also waste electricity
