Personal water purifying device

Abstract

The invention discloses a personal water purifying device, which comprises a water purifying device body and is characterized in that the water purifying device body comprises a peristaltic pump module, a primary filtering module, a secondary filtering module and a tertiary filtering module in sequential connection. By adopting the technical scheme, the personal water purifying device has the beneficial effects that tertiary filtering mode is used; the filtering effect is good; the goal of direct drinking of producing water is realized; a hand-operated peristaltic pump is used; the continuous water inlet and water producing can be realized; the filtering driving pressure is provided for municipal pipeline tap water, so that the effective multistage filtering becomes feasible; the modular design is used; the filtering modules are connected through screw threads; any module can be simply and conveniently replaced; the whole service life of the device is effectively prolonged.

Description

technical field [0001] The invention relates to outdoor water purification equipment, in particular to an individual water purification device. Background technique [0002] Due to its light and portable features, outdoor water purifiers can be used when people go out or provide emergency relief, so they are highly respected. But for special group, as army's field operation, existing water purifier still can't satisfy service requirement. The water purifiers currently on the market mainly have the following defects: first, the filtering effect is not good, and a large amount of impurities still remain in the filtered water, which is not suitable for drinking; When the filter element is contaminated with microorganisms, it will increase the load of the filter element and reduce the service life. After the filter element is polluted, it is not easy to clean and restore, so it can only be scrapped, which greatly increases the cost of use; third, because there is no power suppl...

However, for special groups, such as military field operations, existing water purifiers still cannot meet the requirements for use

The water purifiers currently on the market mainly have the following defects: first, the filtering effect is not good, and a large amount of impurities still remain in the filtered water, which is not suitable for drinking; When the filter element is contaminated with microorganisms, it will increase the load of the filter element and reduce the service life. After the filter element is polluted, it is not easy to clean and restore, so it can only be scrapped, which greatly increases the cost of use; third, because there is no power supply and piped tap water in the field, Existing individual water purifiers usually use airbags or air cylinders to pump water sources. These methods cannot produce water continuously, resulting in low water production efficiency, long time consumption, and affecting marching speed; Fourth, due to the low filtration drive pressure (Using airbags, air cylinders and other driving forces), the filter media of multi-stage filtration is usually only a very thin layer of filter media, and the filtration area is small, it is impossible to achieve effective multi-stage filtration like household water purifiers (multi-stage filter elements, The filter elements are connected by hoses, and because the filter elements of all levels are placed side by side, there is a large pressure loss during filtration)
