摘要： A liquid applicator is described. The liquid applicator includes an applicating head, a buffer in communication with the outside air, a gas-liquid exchanger, and a reservoir supplying a liquid to the gas-liquid exchanger. The gas-liquid exchanger has a wick, a liquid sealing tube covering on the outer peripheral wall of the wick, and a gas-liquid channel disposed between the wick and the liquid sealing tube; the buffer covers on the outer peripheral wall of the liquid sealing tube, and capillary pressure of the liquid sealing tube is greater than capillary pressure of the buffer by 30% or more. The liquid applicator can effectively control the release of a liquid. It can prevent the liquid from leaking out. It features a simple structure, resulting in smooth application and easy manufacturing.
