Water purification machine

Abstract

Provided is a water purification machine. The water purification machine comprises a housing and components of a composite filtration system containing RO membrane components, a booster water pump, a water inlet solenoid valve, a waste water solenoid valve and a low voltage switch, the composite filtration system, the booster water pump, the water inlet solenoid valve, the waste water solenoid valve and the low voltage switch are installed in the housing and connected to form a pure water preparation system. The water purification machine is characterized in that, a water cup component and a water sealing device matched with the water cup component are movably arranged on the housing; the water inlet of the water cup component is equipped with a self-closing valve and communicated with the pure water outlet of the pure water preparation system; a first control element matched with the bottom of the water cup component and a second control element matched with a float switch showing a water level in the water cup component are arranged on the housing to control turn-on or turn-off of the pure water preparation system. In the water purification machine, a pressure barrel is canceled, the water cup component is arranged, and water can be controlled according to requirements. A composite filter core is employed, thus the structure is simple and small in size, joints are decreased and water leakage risk is lowered. The layout is simple and reasonable, the material consumption is little, the cost is lowered greatly, the maintenance is convenient, the occupation space is small and freshness of water quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a pure water machine with reasonable structural layout, low cost and fresh water quality. Background technique [0002] With the continuous deterioration of the ecological environment, the crisis of fresh water resources for human survival has become increasingly prominent. In order to solve the problem of healthy drinking water, various drinking water devices have been born on the market in recent years, which better solve the problem of drinking water in homes and various indoor places. problem. The working principle of the existing household pure water machine is to pressurize the source water and perform coarse filtration by PP filter element, UDF filter element, CTO filter element, etc., and then deeply separate into pure water and concentrated water through RO reverse osmosis membrane, and the pure water enters the storage water The system is stored for drinking, a...

Problems solved by technology

The working principle of the existing household pure water machine is to pressurize the source water and perform coarse filtration by PP filter element, UDF filter element, CTO filter element, etc., and then deeply separate into pure water and concentrated water through RO reverse osmosis membrane, and the pure water enters the storage water The system is stored for drinking, and the concentrated water is directly drained or recycled. Pure water is generally stored in a pressure tank. Since the control system switches between starting water production and standby according to the water pressure in the pressure tank, the pressure tank is always They are all in the state of "full water", that is, the machine will still produce water when the water treated last time has not been used up. The mixture of stale water and fresh water will cause the quality of the effluent water to be stale, even black and smelly. The mechanical failure problem that is prone to occur in the pressure tank leads to the normalization of the "strike" of the whole machine

[0003] On the other hand, the existing household water purifier filter system generally consists of a coarse filter system and a fine filter system. The filtration system is mainly RO reverse osmosis membrane, which is also installed in a plastic cylinder, that is, various filter materials are individually packaged through the plastic cylinder, and then the filter elements of all levels are connected in series with quick connectors and PE pipes. This traditional filter element The combination method takes up a lot of space inside the machine, requires a lot of consumables, and the production process is cumbersome; moreover, there are many interfaces, the risk of water leakage is high, and the production labor cost and after-sales maintenance cost are relatively high.
