Example Embodiment

[0045] Example 1:

[0046] A negative ion air purifier circuit designed with an adjustable voltage-stabilizing circuit, and a DC power supply designed by a voltage-stabilizing chip (a voltage-stabilizing chip with an adjustable function) is used to supply power to an inductive oscillator and a voltage-doubling rectifier circuit, Designed based on the existing mature integrated voltage regulation technology, it can provide a variable voltage regulation voltage for the negative ion air purifier circuit, and set an RCπ filter in the DC power supply to filter out the ripple voltage to stabilize the voltage. The output power supply is further filtered for ripple, so that the DC power supply can provide a working power supply with no ripple voltage, so that the inductive oscillator and the voltage doubler rectifier circuit can operate in a stable power supply environment and avoid the ripple voltage. The circuit operation is unstable, which affects the stabilization of negative air ...

Description

technical field [0001] The invention relates to the fields of air purification and the like, and specifically relates to a negative ion air purifier circuit designed with an adjustable voltage stabilizing circuit. Background technique [0002] Smog, as the name suggests, is fog and haze. But the difference between fog and haze is very big. The aerosol system composed of dust, sulfuric acid, nitric acid and other particles in the air causes visual impairment called haze. Haze is haze (haze). [0003] Fog is an aerosol system composed of a large number of tiny water droplets or ice crystals suspended in the air near the surface. It mostly occurs in autumn and winter, and is the product of condensation (or sublimation) of water vapor in the air near the surface. The existence of fog will reduce the transparency of the air and deteriorate the visibility. If the horizontal visibility of the target is reduced to within 1000 meters, the weather phenomenon of water vapor condens...
