Title:
DIRECT-CURRENT CONTROL CIRCUIT AND METHOD FOR GENERATING NEGATIVE ION STEAM
Document Type and Number:
WIPO Patent Application WO/2019/047285
Kind Code:
A1
Abstract:
The invention relates to the technical field of electrical appliance designing and particularly to a direct-current control circuit for generating negative ion steam. The direct-current control circuit comprises a power supply module, a protection module, a steam generating module, a negative ion generating module, a water pump module and a control module. The invention further discloses a direct-current control method for generating the negative ion steam comprising the following steps: S1, determining whether it is in a negative ion setting mode; S2, running the steam generation module, the water pump module, and the negative ion generating module; S3, only running the steam generation module and the water pump module; S4, controlling an input voltage of the steam generation module and a water output of the water pump module; S5, detecting whether the input voltage is lower than a low pressure alarm threshold; S6, stopping the steam generation module, the water pump module and the negative ion generation module and making an alarm; S7, detecting whether the protection module is open. Thus, through the direct-current circuit which is controlled automatically, generating of negative ions and the steam is more intelligent and safer.
