Description

Foam watering can and quick release structure for foam watering can

The present invention relates to the technical field of foam spraying pots, in particular to a foam spraying pot and a quick-release structure for the foam spraying pot.

The watering can is a common and highly practical spraying device. It is widely used in different places such as families, units, and schools because of its small size, small footprint, easy portability, and hand-held operation. Watering cans are often used in scenes such as air humidification, water spraying for plant watering, and spraying of disinfectant and cleaning solutions for object cleaning and cleaning. When objects (such as vehicles) are cleaned and cleaned, the liquid sprayed from the watering can contains a certain amount of detergent or disinfectant, and the liquid will produce a certain amount of foam. At this time, the watering can is used as a foam spraying can.

In the cleaning and cleaning of objects, such as car cleaning, glass cleaning, etc., it is required that the liquid sprayed by the foam watering can has relatively rich foam and is easy to use and operate. Existing foam watering cans usually increase the pressure inside the pot by injecting high-pressure air into the foam spraying can, so that the liquid can move upwards, and finally foam through the mouth to produce rich foam. During this process, there are extremely high requirements for the airtightness of the entire foam spraying can, otherwise it will not be able to produce a large amount of foam. Due to the high airtightness requirements, the disassembly and assembly of the entire foam spraying can is very cumbersome (usually threaded connection method, which requires a large number of turns), workers will spend a lot of working time when changing the liquid, and it is quite inconvenient to use.

The other end of the foaming pipe 12 is connected to a nozzle 14 through which foam is sprayed. Wherein the length of the foam tube 12 is between 10 cm and 500 cm, the inner diameter of the tube is between 0.8 mm and 20 mm, and the pressure of the liquid-gas mixture in the foam tube is between 8 and 32 PSI. Such setting provides sufficient time, space and conditions for liquid-gas mixing for the air and the solution to be fully mixed in the foaming tube 12 , and then the nozzle 14 sprays abundant foam.

In a specific embodiment, the ratio of the air to the solution in the liquid-gas mixture is between 1:1 and 10:1. The foam spray can 1 can be used in general common cleaning occasions, such as car cleaning, glass cleaning, etc., between the gas-liquid mixing ratio, the mixing uniformity, fluidity, and foaming ratio of the liquid-gas mixture are at the required level for use. In the best state, it can produce rich and delicate foam, thereby ensuring the cleaning or cleaning effect of different needs.
