Outdoor water purification system

Abstract

The invention discloses an outdoor water purification system. The system comprises a water drawing assembly, a water purifier main body, a water outlet device and a flow limiting valve, wherein the water purifier main body comprises a water purifier shell and a multi-stage composite filter element; the water drawing assembly is communicated with the water purifier main body through a water pipe and is sequentially provided with a front filtering assembly, a connecting water pipe and a water pump in the drawn water flowing direction; and the water pump comprises a shell, a cylinder body, a piston, a connecting rod, a crank, a hand-cranking transmission device, a one-way valve and a connecting water pipe assembly. The composite filter element has a composite filter structure, which is sequentially provided with a first-stage sterilization filter material, a second-stage heavy metal removal filter material, a third-stage turbidity removal filter material and a fourth-stage sterilization filter material in the water flow direction. The final-stage filter material is connected with a water outlet pipe through a flow-limiting valve; and a military kettle adapter interface, a travel kettle adapter interface and a protection cover adapter interface are simultaneously arranged at the bottom of the water purifier shell. The system is simple and reasonable in structure and convenient to carry, water is subjected to multi-stage purification and sterilization treatment through pretreatment and the filter element in the rear end; and in addition, the system is convenient to carry in wars, field operation, and travel, does not need any electric power, is safe to use, and is suitable for outdoor application.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to an outdoor water purification system adopting manual water drawing and graded directional purification technology. Background technique [0002] Field operations, field scientific research, field trips, unidentified water sources in the field cannot be directly drunk, and the outdoor surface raw water contains various unidentified solid impurities, floating objects, bacteria, microorganisms, animal secretions, organic matter, pesticide residues, environmental hormones and heavy metals and other harmful ingredients; once drinking pathogenic bacteria, viruses and chemical toxins, the human body will quickly lose its vitality, and there is no cure for unknown reasons, which will seriously endanger life. [0003] As mentioned above, when the water source for field activities is lacking, the quality of the unidentified raw water needs to be treated before drinking. There a...

AI Technical Summary

Problems solved by technology

There are two main types of outdoor water purification systems in the existing market. One type has a large flow rate, simple filtration, and low pollutant removal efficiency, which cannot effectively kill bacteria and microorganisms. It only filters without purification and cannot guarantee water quality safet
