Problems solved by technology
Due to the need to cooperate with the power supply and motor drive system, the device is complex and heavy, which is not conducive to portability
In addition, the device is biased towards theory, and it is difficult to run stably for a long time
[0007] CN 101104527U discloses a portable manual seawater desalinator, the structure of its piston and pressure control valve is complicated, which determines that the size of the parts is relatively large
The increase of the pressurized section will directly lead to a decrease in the pressure of the water, making it difficult to provide sufficient working water pressure for the reverse osmosis membrane
In addition, the structure of the stem 23 of the pressure control valve is difficult to realize

Embodiment 1
[0043] Such as figure 1 The shown portable water purifier using the low-pressure nanofiltration membrane has a base 1 at the bottom, and the low-pressure nanofiltration membrane 6 is located above the base 1, the shell 2 is connected with the base 1, and the top cover 4 is installed on the top of the shell 2.
[0044] The base 1 includes a water inlet 11 and an L-shaped water inlet channel 12. The L-shaped water inlet channel 12 is provided with a first one-way device, and is connected to a second one-way device through a transverse hole 13. The downstream of the second one-way device is Low pressure nanofiltration membrane6.
[0045] The first one-way device comprises the first tapered pipe 15 that is communicated with the L-shaped water inlet channel 12, steel ball 16 is placed in the first tapered pipe 15, and the steel ball top is provided with the first limit lever 17 (for limiting the steel ball 16 is lifted up by the movement range). Similarly, the second one-way devi...

The invention relates to a portable water purifier utilizing a low-pressure nanofiltration membrane. The water purifier comprises a base (1), a central pipe (3), a shell (2) and a top cover (4), wherein the outer side of the central pipe (3) is provided with the nanofiltration membrane, and an L-shaped water inlet passage (12) and an L-shaped water inlet bypass (14) of the bottom are respectively provided with a single-directional apparatus; and the inner side of the central pipe (3) is provided with a pressurizing assembly, the pressurizing assembly comprises a piston barrel (31) fixed in the middle part of the base (1), a piston rod (32) arranged inside the piston barrel (31) and a piston head (33), after the piston rod (32) is pulled outwards, a piston cavity (35) is formed inside the piston barrel (31), and the piston cavity (35) is communicated with the L-shaped water inlet bypass (14) by virtue of a transverse hole (13).
Description
【Technical field】 [0001] The invention relates to low-pressure nanofiltration water treatment technology, and is especially suitable for outdoor water purification technology. 【Background technique】 [0002] At present, the filter elements used in portable water purifiers on the market are generally activated carbon particle filter elements, ceramic filter elements, ultrafiltration membrane filter elements, or filter elements combined with the above filter elements. These filter elements can remove sediment, rust, suspended solids, Harmful substances such as residual chlorine and bacteria, but the removal effect of inorganic salt ions in raw water is poor, especially heavy metal ions, and viruses and organic substances cannot be effectively removed. [0003] Portable water purifiers are generally used in the field of outdoor water purification. Since the water quality of most outdoor water sources does not meet the municipal tap water standard, or even is polluted, if the w...
