Description

technical field [0001] The invention relates to a water purification device, in particular to a portable outdoor cleansing drinking water device. Background technique [0002] Drinking clean water is necessary for people to ensure their health. It is difficult for people to carry a large amount of clean water in outdoor activities, such as outdoor adventure, outdoor survival, outdoor camping, tourism, geological exploration, emergency rescue, earthquake flood, international rescue, individual combat, etc. How to easily obtain clean water has become a field The issues that people are most concerned about during the event. [0003] The wild water source is the source for people to obtain water in the wild, but the situation of the wild water source is extremely complicated. The water often contains sediment, humus suspended matter and various harmful parasites, bacteria, viruses and toxic organic substances and toxic inorganic salts dissolved in water. , Some water sources c...

AI Technical Summary

Problems solved by technology

Adsorption is a treatment method that uses porous substances with adsorption capacity to remove impurities in water. Activated carbon is commonly used as an adsorbent, which can remove some organic pollutants, odors, and colors in water, but it is harmful to heavy metal ions and harmful substances. The removal ability is limited, and once it encounters highly polluted water sources, it is easy to absorb and saturate and completely lose the adsorption effect

Membrane separation method is a technical method that uses a semi-permeable membrane to selectively separate molecules of different particle sizes in water. Membrane separation method can effectively remove fine suspended particles, molecular or ionic organic and inorganic substances, bacteria and viruses, etc. Ultrafiltration and reverse osmosis are commonly used, but the pore size of the membrane is very small, and it is easy to be blocked during use. Therefore, it has certain requirements for pre-treatment, and the outdoor drinking water purification device is small, and it is difficult to achieve it only by the internal treatment of the water purifier. The requirements of long-term use are extremely unsuitable for field operations or travel expeditions

[0005] CN201520409063.2 discloses a portable water purifier, which includes a water inlet part, a water filter part, and a water outlet part connected in sequence. The water enters from the water inlet and can be used after being filtered by the filter water layer, but it needs pressure when filtering. Can only be used in conjunction with other water outlet equipment, easy to block, need frequent cleaning and other problems, not suitable for complex toxic and harmful water source conditions in the field

CN201620299693.3 discloses a portable water purifier, including a cylindrical body, an ultrafiltration filter element in the body, activated carbon filled in the inner wall of the body and the ultrafiltration filter element, quartz sand filter particles, the first filter screen at the water inlet end and the water outlet The second filter at the end uses a plastic bottle stuck in the water inlet to send water in, and then filters through the first filter, activated carbon, quartz sand, ultrafiltration membrane, and the second filter to obtain directly drinkable water, but It only works under gravity, the water outlet speed is slow, and the water production efficiency is low; there is no pre-treatment of water, and there are many impurities in the water, which may easily cause blockage of the ultrafiltration filter element; it is very easy to absorb and saturate, and has poor removal ability for heavy metal ions and bittern; Problems such as poor treatment of highly polluted water

CN200920298258.9 discloses a portable water purifier, which includes a stainless steel pressure tank, three filters of primary, secondary and tertiary, when in use, add mountain spring water or unpolluted surface water into the stainless steel pressure tank, and then use Household air pumps are used to pressurize the water, and the water can be used as drinking water after three-stage filtration. However, there are problems such as many items used, large volume, and difficulty in carrying by a single person, and it is only suitable for mountain spring water or unpolluted surface water.

CN201410335097.1 provides a portable water purification device, including an outer cover with a piston and a composite filter element, a lower cover with a water storage box, an ultraviolet lamp and a power supply, and the water is directly poured into the raw water of the water purifier during use The cavity is pressed by the piston so that the water passes through the composite filter element, and then flows into the water tank after purification, and is used after ultraviolet disinfection, but there is a problem that the water is directly added to the water purifier, and the impurities in the water are easy to block the filter element, and the service life is short. ; Requires ultraviolet lamps, batteries, large volume, not easy to carry and other problems, its applicability to complex conditions in the field is doubtful

CN201720018807.7 provides a portable water purifier, which uses a super battery to drive the piston movement on the electric push rod, sucks the water that has filtered out large particles into the clean water tank, and filters and absorbs it through a multi-layer filter element to ensure The cleaning of water, and the cleaning brush can move up and down to realize the external cleaning of the filter element, but the battery life of this device is limited due to the lack of electric facilities in the field, and the second is that the filter screen of the water inlet can only filter large particles, which is harmful to impurities in the water. The removal ability of the water purifier is very limited, and the cleaning brush can only brush off the debris on the surface of the filter element, and the cleaned debris still exists inside the water purifier and has not been discharged, so the effect of preventing the filter element from clogging is poor. The third is to use electric drive. Power conversion devices such as electric motors are required, which increases the size and weight, is not easy to carry, and also greatly increases the manufacturing cost, and the economy is poor. Similarly, the adaptability to complex environmental conditions in the field is doubtful.

[0006] To sum up, there is no effective device that can solve the above problems. Therefore, there is an urgent need for a portable field clean drinking water device that can be applied to water sources under complex environmental conditions in the field, and is small in size and manually pumped.
