Description

Air hand washer based on double fluid atomizing technique

Technical Field

The utility model relates to a hand cleaner, in particular to an air hand cleaner based on a double-fluid atomization technology.

Background

In conventional hand washing processes, the water stream tends to play two roles, namely dissolving the stain and carrying away the stain. However, the amount of water for dissolving the stains is very small and only accounts for 1% -5% of the total water consumption, and the rest of water only plays a role in flushing away the stains, so that a large amount of water resources are wasted.

The Chinese patent document CN202901439U discloses an air pressurizing water-saving faucet, which comprises a faucet main body, a water outlet nozzle and a pressurizing part, wherein after water flow is pressurized by the pressurizing part, the water flow is fully mixed with air while being depressurized and diffused, so that the water dispersibility is improved, and the water-saving purpose is achieved. Chinese patent document CN2828487 discloses a water-saving tap comprising a spray nozzle through which water flows to form a large number of fine water droplets, which spread in a large area, so that the dispersion of water is improved, thereby achieving the purpose of saving water.

The principle of the two water saving modes of the traditional water saving faucet is to reduce the water quantity in a unit area, but the water waste problem of the water can not be well solved by using most of water to wash away a small part of sewage for dissolving stains. The corresponding data show that the water saving effect is about 40% compared with the traditional water saving mode.

The novel air hand washing concept uses the compressed air atomization hand washing device, and based on the commonality of the fluid carrying dirt, the air replaces most of the water which is wasted by washing away the dirt, so that the water waste in the hand washing process is greatly reduced. After experimental verification, the water saving effect can reach more than 90%, and the water saving rate of the water saving tap is greatly improved. If the air hand washing device is adopted, the water can be saved by about 2.04x10 per year by calculating the water saving rate of the hand washing by 85 percent conservatively ⁹ Ton, i.e. every 2 days, is equivalent to a total water storage capacity of a western lake. It can be seen that the compressed air atomizing hand washing device which replaces most of water with a large amount of air has a very wide prospect.

Chinese patent document CN104384037a discloses a two-fluid atomizing nozzle, which comprises a nozzle fluid connector, a liquid swirl plate, a two-fluid atomizing cavity and a nozzle, wherein the liquid passes through the liquid swirl plate and then performs spiral movement, and collides with the pressurized gas at a specific angle, thereby atomizing the liquid. The double-fluid atomizing nozzle is a primary atomizing nozzle, has a good atomizing effect and is convenient to disassemble and assemble. However, the two-fluid atomizing nozzle is an industrial nozzle and is used for an industrial wastewater evaporation process, so that the industrial wastewater atomizing effect and the detachable assembly property of the nozzle are ensured, and the hand washing effect of the civil atomizing nozzle is not considered.

Chinese patent document CN 105822824A discloses a faucet for atomizing water by human body pressure, and also uses a liquid cyclone to atomize water, but the actual effect is not good but there is room for improvement because the impact angle of high pressure air on water is not considered. Meanwhile, the device has certain requirements on the weight of the person, and the danger of toppling possibly occurs when the user stands, so the device is small in applicable crowd range.
