  • Patent number: 12180647
    Abstract: A garment steamer, including: a water tank; an evaporator assembly, communicated with the water tank and configured to generate steam; wherein the evaporator assembly includes a first heating member and a second heating member; a water pump, configured to transfer the water from the water tank to the evaporator assembly; and a switch assembly, configured to control the first heating member to be conducted and disconnected from a power source. When the first voltage is input to the garment steamer, the switch assembly controls the first heating member to be conducted, and the first heating member and the second heating member operate simultaneously; and when the second voltage is input to the garment steamer, the first heating member is disconnected from the power source, and only the second heating member is conducted and operates.
