Description

Technical Field

[0001] The present invention relates to the technical field of water purification, and particularly to a portable water purification device for field training. Background Art

[0002] Field training, as an important way to improve physical fitness and survival skills, enhances people's adaptability in harsh environments and boosts their confidence in dealing with emergencies through survival training in the wild. By using the harsh survival environment in the wild and activities such as long-distance hiking and load-bearing walking, the physical strength, endurance, and mental toughness of the trainees are enhanced. Therefore, field training is an essential skill for professional groups such as soldiers, explorers, and scientific expedition members.

[0003] A portable water purification device is a lightweight and efficient water purification equipment, mainly used to provide clean drinking water in the wild, disaster areas, or scenarios lacking safe drinking water sources. During activities such as hiking, camping, and field training, field training personnel use the portable water purification device they carry to filter and purify pollutants in the water source, solve the possible pollution problems of natural water sources, avoid disease infections caused by drinking water during field training, and at the same time reduce the supplies required during field training, improving the effect of field training.

[0004] However, when the existing portable water purification devices for field training are in use, most of them are in an integral structure. After filtering the water source, they cannot clean the filtered residues in a timely manner, greatly reducing the service life of the portable water purification device. Moreover, during field training, it is very easy for the equipment to be lost or damaged. As a result, the existing portable water purification devices for field training cannot be disassembled and assembled conveniently when carried, leading to the inability to continue using the portable water purification device once it is damaged during field training. At the same time, when multiple people conduct field training, each person needs to carry their own portable water purification device, increasing the equipment burden required for field training and affecting the training effect of field training. In view of this, a portable water purification device for field training is provided to overcome the above defects. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies existing in the prior art and propose a portable water purification device for field training.

A filtering and purifying block 34 is arranged inside the filtering cavity 33. The filtering and purifying block 34 is composed of activated carbon and an ultrafiltration membrane. The annular layout design of the filtering component 3 maximizes the use of space and divides the filtering cavity 33 into levels. The activated carbon and the ultrafiltration membrane are used to filter and purify the water source. Specifically, in the filtering cavity 33 formed by two adjacent carrying rings 31 during use, granular activated carbon (particle size 1-3 mm, iodine value ≥ 1000 mg / g) is filled in the upstream carrying ring to adsorb odors and organic substances, while a hollow fiber ultrafiltration membrane (pore size 0.01 μm, cut-off molecular weight 50 kDa) is arranged in the downstream carrying ring to intercept bacteria and colloidal particles. The carrying ring 31 includes a ring body 311 arranged at the bottom of the assembly housing 11. In the present invention, the ring body 311 is made of fiberglass material to ensure the strength of the ring body 311, and the material can be rotated according to the usage requirements during specific use.

Insertion blocks 49 are provided on both sides in the middle of the collection housing 41. The connection ring 314 and the insertion blocks 49 are connected by the fixing rod 5. When the fixing rod is lost, a branch can be used instead of the fixing rod 5 on the spot to lock the filtration component 3 and the collection component 4. The filtered and purified water source is collected through the collection chamber 43, and the water source is heated and sterilized by the heating block 44, further improving the drinking water quality during field training.

[0033] Working principle:

[0034] When using the present invention, collaborative carrying allocation is carried out according to the personnel composition during field training. After the allocation is completed, field training is carried out. When it is necessary to use the portable water purification device, the assembly ring 312 at the top of the carrying ring 31 of the filtering component 3 is inserted into the docking groove 12 at the bottom of the pumping component 1, and rotated clockwise to lock. Then, the fixing rod 5 is passed through the connecting rings 314 on both sides of the filtering component 3 and the insertion block 49 of the collecting component 4. One end of the water pipe 2 is connected to the water source, and the other end is inserted into the water inlet hole 110 of the pumping component 1 to complete the preparation for water source input. After the preparation is completed, the user presses down the pressing housing 15, driving the downward pressing rod 18 to push the pressing plate 19 to compress the internal space of the assembly housing 11, generating an instantaneous pressure to make the water flow through the water outlet hole 14 of the partition plate 13 and into the filtering component 3. The water flow enters the filtering cavity 33 of the upstream carrying ring 31, flows through the activated carbon layer, adsorbing the odor, organic matter and suspended matter in the water. The water flow treated by the activated carbon then flows to the downstream carrying ring 31, and the bacteria and colloidal particles are intercepted by the ultrafiltration membrane to complete the secondary purification. The filtered purified water flows into the collecting cavity 43 of the collecting component 4, and the heating block 44 at the bottom is started to heat. When the water temperature reaches 100 °C, the built-in temperature sensor cuts off the power supply to prevent dry burning. After boiling, it flows to the kettle through the drain hole 45 and the external silicone hose or directly removes the collecting cavity 43 for direct drinking. After use, the installation block 322 of the placement plate 32 is pulled out, and the through hole 323 is rinsed reversely with clean water to remove the sediment deposited on the surface of the activated carbon.

[0035] When a component is damaged, the faulty carrying ring 31 is disassembled, and the assembly ring 312 of the spare carrying ring 31 is inserted into the assembly groove 313 of the adjacent ring body. After rotation and locking, the filtering function is restored. If the fixing rod 5 is lost, a tree branch with a suitable diameter is selected on the spot and inserted into the connecting ring 314 and the insertion block 49 for temporary fixation. When an individual is separated from the teammates, the two carrying rings 31 carried by oneself are combined, and the activated carbon layer and the ultrafiltration membrane are filled inside and stacked at the water bag inlet, and the water source can be filtered by gravity flow.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
