Although the utility model prevents makeup and toiletries from being accidentally squeezed out, causing waste and polluting the external environment, the structure is simple, easy to use, and has high practicality, but when people use the emulsion pump because the emulsion pump is sprayed The emulsion is often sprayed to the same location, resulting in a particularly large amount of application at this location, it is difficult to evenly distribute the emulsion in a certain area, and there is room for improvement.
