Technical Field

[0001] The present invention belongs to the technical field of emulsion pump structures, and more specifically, particularly relates to an emulsion pump with a water inlet prevention mechanism. Background Art

[0002] An emulsion pump is usually installed on the opening of a container for holding a product. During bathing, sometimes water leaks into the packaging container through the emulsion pump, causing the product in the container to be contaminated and deteriorated. For example, when the emulsion bottle falls, or the bottle body is soaked by the water during bathing due to injury, the water will leak into the container through the air compensation channel provided to prevent negative pressure inside the container.

[0003] Based on the above, the currently used emulsion pumps are provided with air compensation channels, and the air compensation channels do not have the function of preventing water from entering, lacking a water inlet prevention mechanism. Moreover, the assembly is not tight enough, prone to generating gaps, and the internal structure is complex and not easy to assemble.
