Description

A pumpless RO pure water machine

technical field

The utility model relates to water purification equipment, in particular to a pumpless RO pure water machine.

Background technique

At present, the water purifiers on the market cannot meet people’s immediate use due to the small water output, and generally have water storage tanks. Usually, when people are not using the pure water machines, the pure water machines will store filtered pure water in the water storage tanks. Preservation, because the existing water storage tank is an airbag water storage tank, its working principle is that when there is no water, the airbag fills the space inside the tank, and when the pure water machine is working, the filtered pure water will pass through the booster pump set in the pipeline Press it into the airbag-type water storage tank, and use the booster pump to strengthen the water pressure to overcome the pressure inside the airbag to press down the airbag to store water in the tank. When people use it, turn on the faucet, and the bottom of the water storage tank will press the airbag inside and outside. Under the action of pressure difference, it bulges upwards to press the pure water stored in the tank out from the faucet for people to use. But the existing airbag type water storage tanks that pressurize the stored pure water are mostly made of plastic, and the inside of the tank cannot be opened and cleaned. It is easy to breed bacteria after long-term use, causing secondary pollution of water. People drink the pure water produced by this kind of pumpless pure water machine that uses airbag water storage tank to work for a long time, which is extremely unhygienic and not conducive to people's health. At the same time, the existing RO pure water machine overcomes the water storage tank airbag in order to strengthen the water pressure. Most of the internal pressure uses a booster pump, which increases the cost of the product and is not conducive to the market popularization of the entire product. Therefore, the above-mentioned drawbacks urgently need to make new improvements to the current technology.
