The invention relates to a water purifier and a method for protecting a water pump by using the water purifier. The water purifier comprises a raw water barrel, a water suction pump, a filtering system and a control assembly, wherein a gas-water liquid level control tank is installed on a raw water pipe, raw water in the raw water barrel is sucked by the water suction pump and collected to the gas-water liquid level control tank, and then flows to the filtering system to be filtered to generate purified water, the generated purified water is discharged through a purified water pipe, the generated concentrated water flows back to the raw water barrel through a water return pipe, an inductive switch is arranged on the outer wall of the tank body of the gas-water liquid level control tank, and the control assembly is in control connection with the inductive switch, the water suction pump and the filtering system. The water purifier is matched with the water pump protection method, the gas-water liquid level cont
