[ background of the invention ]

Since field or outdoor water sources cannot be directly drunk without being treated, the portable water purifier is important for personnel who often operate in field or outdoor environments and the personnel.

Currently, most portable water purifiers are bulky. In addition, these portable water purifiers may be further equipped with a battery or a pressurizing device in order to provide a required operating pressure of the water purifying cartridge. For example, CN201710082950.7 discloses a field solar water purifier, which comprises a folding solar panel, an external faucet, an environmental protection water tank, a self-priming water pump, an integrated water purifier body and a portable draw-bar box. Due to the design of the solar panel and the self-priming water pump, the product has larger volume, can meet the water demand of partial field or outdoor, but is not suitable for being carried by a single person.

For another example, CN201610730403.0 discloses a portable water purifier with self-priming function, which at least includes a water suction chamber and a water purifier connected to a water inlet electronic valve of the water suction chamber, wherein a piston is disposed in the water suction chamber, and the piston is rotatably connected to a crank-link structure through a rotating shaft. Due to the design of the piston, the water purifier has the defect of large volume in order to ensure the stroke of the piston. In addition, because the water inlet electromagnetic valve is adopted, a power supply device is required to be connected, and the water inlet electromagnetic valve is inconvenient to use in the field or outdoor environment.

The utility model discloses in, in order to realize the outdoor purpose that can drink the water purification at any time, the membrane filter core is enhancement mode hollow fiber membrane filter core, the hollow fiber membrane that ZL200910259973.6 for example discloses.

Preferably, the middle part of the reinforced hollow fiber membrane filter element can be provided with a breathable membrane thread which is prepared from hydrophobic materials, and the pore diameter can be controlled to ensure that water cannot infiltrate membrane pores in the membrane thread, so that water cannot permeate the membrane thread. Air can easily permeate through the membrane due to hydrophobicity, so that the air permeability function is obtained. After the membrane filter element is cleaned by the breathable membrane yarn, air in the membrane filter element can be discharged through the breathable membrane yarn, and the water yield of the membrane filter element is ensured.

Optionally, the post-filter element 4 is an activated carbon fiber filter element, and is detachably mounted in the cavity of the upper end cover 7 by a mechanical connection method, so that the replacement is convenient.

In order to protect the membrane filter element, a water inlet head 8 is preferably arranged at the far end of the water suction pipe 1, and a filter grid is arranged in the water inlet head 8 and used for filtering larger particle impurities such as silt in a water source.

Preferably, the water purifier is also provided with a dust cap 9 matched with the water suction port 2.

When in use, the water inlet head 8 is placed in a water source (such as river water), and a user absorbs water through the water suction port 2. Water from a water source enters a hollow area of the lower end cover 6 through the water suction pipe, permeates the membrane filter element 3 under the action of suction force to realize filtration, then flows out from the water outlet end of the membrane filter element 3, enters the post-positioned filter element 4, is treated by the post-positioned filter element 4, enters the water suction port 2 through the middle part of the upper end cover 7, and can be directly drunk.

The utility model discloses a portable self-priming water purifier simple structure, small in size, dead weight are light, and field or outdoor operation personnel can every people carry separately, during the use only need with the end of the pipe that absorbs water insert in the water source can.

Because the membrane filter element and the postposition filter element are both installed in the upper end cover and the lower end cover in a mechanical connection mode, the membrane filter element and the postposition filter element are detachable components, can be cleaned and replaced when the filter element is polluted, can practically ensure the drinking water quality, and are particularly suitable for field or outdoor operators to use.
