Reverse osmosis water purifier capable of forming water pressure by air entrapping

Abstract

The invention relates to the technical field of water purifiers, in particular to a reverse osmosis water purifier capable of forming water pressure by air entrapping, which comprises an air entrapping device, a multi-stage filtering device taking a reverse osmosis membrane as a core filtering medium, a raw water container and a water purifying container; a connecting air pipe is provided on the side of the air entrapping device, the raw water container is connected to the other end of the connecting air pipe, a connecting water pipe is arranged on the side face, away from the air entrapping device, of the raw water container, a membrane pretreatment device is arranged at the other end of the connecting water pipe, and a vertically-arranged water filtering pipe and a sewage discharging pipe provided with a second water valve are arranged at the bottom of the membrane pretreatment device; the other end of the water filtering is connected to a reverse osmosis membrane cavity with the reverse osmosis membrane inside, the reverse osmosis water purifier which adopts the reverse osmosis membrane as a core element and forms effective water pressure by air entrapping is adopted, and the air entrapping device is used for pressurizing an internal aqueous solution of the raw water container or performing air entrapping and pressure applying on a pressurizing cavity, so that the effectivewater pressure is formed, and the water purifier can be suitable for an environment which cannot form or is difficult to form effective water pressure but has sanitary and unguaranteed water sources;and the application range and field of the reverse osmosis water purifier are expanded.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a reverse osmosis water purifier capable of adding air to form water pressure. Background technique [0002] Reverse osmosis water purifier is a kind of water purification equipment with reverse osmosis membrane as the core filter medium and multi-stage filter medium for water purification treatment. Its core technology and components are reverse osmosis technology and reverse osmosis membrane filter medium, so that water molecules From one side of the filter medium to the other side of the filter medium, because the pore size of the filter medium of the reverse osmosis membrane is very small, various viruses, bacteria, solid solubles, and polluted organic matter cannot pass through the filter medium of the reverse osmosis membrane at all, so as to achieve The purpose of water purification. [0003] But, existing reverse osmosis water purifier is to utilize existing hydr...

Problems solved by technology

[0003] But, existing reverse osmosis water purifier is to utilize existing hydraulic pressure (as tap water hydraulic pressure) or / and the hydraulic pressure that pump produces to prepare purified water now; Once lacking existing hydraulic pressure or / pump, existing Reverse osmosis water purifiers cannot produce clean water, so existing reverse osmosis water purifiers can only be used in environments with existing effective water pressure or / and pumps to generate effective water pressure, such as tap water or / and can drive Residential homes with pumps, public places with running water or / and the ability to drive pumps, etc., but not suitable for environments where it is impossible or difficult to drive pumps, unable or difficult to form effective water pressure, but there are water sources that are not guaranteed sanitation, such as outdoors, Geological disaster environment where hydropower is destroyed, etc.
