Description
Technical Field
[0001] The utility model relates to the technical field of foaming pumps, mainly to a micro foaming pump. Background Art
[0002] Existing foaming micro pumps are commonly used in automatic foaming equipment, such as hand sanitizers and soap dispensers, to mix air and liquid to produce rich foam. Micro pumps are suitable for a variety of media, such as water and non-oily liquids, and are typically self-priming, capable of handling water-air mixtures. Due to their compact size, low noise, and maintenance-free design, they are widely used.
[0003] Existing foaming pumps are difficult to repair due to their small size and compact internal structure. The liquid and gas entering the chamber are not adequately isolated, leading to a small amount of premature mixing over time. The gas and liquid mixing time is short, hindering the foaming process. Micro-pumps typically have limited flow and pressure, making them inadequate for applications requiring higher flow or pressure. Furthermore, insufficient gas flow into the foaming pump results in insufficient foam volume and a suboptimal foaming effect. Utility Model Content
