  • the spray can is a common and highly practical spraying device. It is widely used in different places such as homes, units, schools, etc. because of its small size, small footprint, easy portability and hand-held operation. Spray cans are often used in air humidification, water spraying for plant watering, and spraying of disinfectants and cleaning liquids in the cleaning and cleaning scenarios. When cleaning and washing objects (such as vehicles), the liquid sprayed from the spray can contains a certain cleaning agent or disinfectant, and the liquid generates a certain amount of foam. In such condition, the spray can is used as a foam spray can.
  • the liquid sprayed from the foam spray can is required to have relatively rich foam, and it is required to be easily operated.
