Description

Portable Water Purifying Device

The present invention relates to a water purifier, and more particularly, to a water purifier that operates without power supply.

Soldiers who are training in the field or are actually operating are often in areas where logistical support is poor. If logistics support is not smooth, one of the most uncomfortable things is water, which is one of the essential elements for life support.

Traditionally, soldiers have carried a canteen as a basic military item, since the canister's capacity is only about one liter, which makes it difficult to hold one day with a canned bottle, especially several hours on hot or active days. Water may run out in a bay.

When the water in the bottle is depleted, drinking water from the spring or river water, and filling the bottle with water, such as drinking water locally can cause diarrhea or dysentery if the drinking water does not meet the constitution of the drinker or contains a lot of impurities. In particular, when only extremely turbid water, contaminated water, or sea water is available, the likelihood of such side effects is even greater. Particularly in modern warfare, the possibility of a chemical war or a biological warfare cannot be ruled out. Therefore, in actual battlefields, it is very dangerous to drink any water because of concern about chemicals or bacteria.

Therefore, there is an urgent need for a method that allows soldiers who are training in the field or in actual operations to drink water with confidence even when water supply is not smooth.

Water purifiers that provide drinking water by purifying highly polluted water have been widely used in industrial sites, restaurants, restaurants, and homes, but conventional water purifiers are bulky and heavy, and thus cannot be used portablely. Moreover, since the existing water purifier is operated by a pump driven by electric power, if a portable water purifier is manufactured in a conventional manner, a large battery or a generator and fuel for power supply must be carried separately, and thus volume and weight are increased. It is a problem.

Some water purifiers have been proposed for use by field troops, explorers, or local residents with poor water conditions.

An example of such a water purifier may include a filter tube having an absorption port at a lower end thereof and an outlet at an upper end thereof. These water purifiers are used in such a way that the outlet is immersed in the user's mouth while the absorber is immersed in a water source. However, this water purifier may be inconvenient to use because it requires a lot of power to suck water to drink water, or may have low water purification ability for fine particles or bacteria.

As another example of a conventional portable water purifier, water that is to be purified by gravity passes through a filter. However, this water purifier has a problem that it is difficult to purify the foreign matter having a large particle size because the pressure required to pass the water through the filter is very low filtration capacity, it may take a considerable time for the water to pass through the filter. If the water purification ability is limited like this and the time required for water purification is long, it is clear that the mobility and combat power of the field forces may be reduced.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and to provide a portable water purification device which is small in size and capable of providing a drinking water with a sufficient amount of water for drinking quickly and without power.

In a preferred embodiment, a piston rod for driving the piston is provided below the piston, and the piston rod is rotatably coupled to the pressure presser.

It is desirable to provide pretreatment filtration means for filtering out large foreign matter contained in water entering the pressurized room. As such a pretreatment filtration means, a net can be used.

On the other hand, the filter assembly preferably includes a reverse osmosis filter.

The portable water purifying device according to the present invention can be operated only by the user's muscle power without using electric power, and by using the lever principle, the human body can drink contaminants by maximizing amplification of hand grip force or other muscle power to filter contaminants. The amount of water needed to clean water can be quickly treated anywhere.

In addition, the portable water purifier according to the present invention is simple in structure and convenient to carry, and it is possible to purify water in areas where there is a possibility of contamination as well as water that is already contaminated and can not be contaminated.

The pumping unit mentioned above is demonstrated. One end of the pressure support 80 is fixed to one side of the fixing ring 28 provided on the lower outer circumferential surface of the pressure cylinder 10. One end of the pressure presser 90 is coupled to the lower end of the piston rod 26 by a pivot pin 92. The pressure support 80 and the pressure presser 90 are coupled by a connecting pin 94 that operates as a rotating shaft. Handles 88 and 98 are provided at the other ends of the pressure support 80 and the pressure presser 90, respectively.

In order to be able to increase the stroke interval of the piston while reducing the distance between the handles 88 and 98, at least one of the pressure support 80 and the pressure presser 90 is provided with a bent portion. In the embodiment shown in FIG. 1, two bends are provided in the pressure support 80, such that the pressure support 80 is coupled to the stationary ring 28 by a first horizontal portion 82.

The distance from the pivot pin 92 to the connecting pin 94 and the connecting pin 94 so that a large force can be applied to the piston rod 26 even if the handle 98 is pressed with a small force by the lever principle. The ratio of the distance to the handle 98 is preferably set to be about 1: 3 to 1:10.

The portable water purifier of FIG. 1 operates as follows.

First, the user checks whether the strainer filter 30 and the suction hole 12 of the pressure cylinder 10 are connected by the absorption pipe 32, and the filter assembly 50 and the drain hole 14 of the pressure cylinder 10 are checked. ) Is connected by the filter connector (40). In addition, the user checks whether the outlet 53 at the bottom of the filter assembly 50 and the water bottle 70 are connected by the water bottle connecting tube 60. In one embodiment, absorber tube 32, filter connector 40 and water bottle connector 60 are fixedly attached to the locations described above at the time of manufacture of the device. However, in the modified embodiment, connection ports such as one-touch fittings are provided at both ends of the absorption pipe 32, the filter connection pipe 40, and the water bottle connection pipe 60, for example, so that the user can attach or detach them. It may be.

With the pressure support 80 and the pressure presser 90 coupled by the connecting pin 94 and the piston rod 26 and the pressure presser 90 coupled by the pivot pin 92, the user Inserts the piston 24 into the pressurized cylinder 10 from below the pressurized cylinder 10, and fastens the fixing ring 28 to the lower outer peripheral surface of the pressurized cylinder 10.

In this state, the user immerses the sieve filter 30 in a water source, while holding the handles 88 and 98 of the pressure support 80 and the pressure presser 90 with both hands. Apply force so that the distance of 88, 98) is farther away. Here, the piston rod 26 is moved downward in the drawing by the action of the pressure presser 90, whereby the piston 24 is also conveyed downward. As the piston 24 moves, the internal pressure of the pressurization room 22 is lowered, and water filtered by the filter net filter 30 with a large amount of foreign matter is transferred into the pressurization room 22 through the absorption pipe 32. At this time, the check valve 18 is opened, and the check valve 20 is closed.

The user then applies a force to bring the distance between the pressure support 80 and the handles 88, 98 of the pressure presser 90 close by both hands or by one hand grip. Here, the piston rod 26 is moved upward in the figure by the action of the pressure presser 90, whereby the piston 24 is also conveyed upwards. As the piston 24 moves upward, the internal pressure of the pressurization room 22 rises, and water inside the pressurization room 22 is supplied to the filter assembly 50 through the filter connecting pipe 40. At this time, the check valve 18 is closed and the check valve 20 is opened. The water supplied to the filter assembly 50 is purified through a four-stage filter filtration process in the unit filters 54, 55, 56, and 57, and exits through the outlet 53 at the bottom to filter the filter tube 60. Through the water bottle 70 is collected.

As the relative movement of the handles 88, 98 of the pressure support 80 and the pressure presser 90 is repeated, the suction and discharge in the pressure room 22 is repeated, and the pressure is discharged from the pressure room 22. The water to be purified is filtered by the filter assembly 50. And, as this process is repeated, the water is filled in the pressure room 22, the efficiency of the suction / discharge is further increased. When the water bottle 70 is sufficiently filled with water, the user may remove the lid of the water bottle 70 and drink the water collected by the purified water. In addition, by using a sealing lid instead of the lid provided with the inlet 72, the water-filled water bottle can be used for drinking when necessary.

On the other hand, while the relative movement of the pressure support 80 and the pressure presser 90 is in progress, the pressure support 80 remains firmly fixed to the fixing ring 28 below the pressure cylinder 10, The relative momentum of the pressure support 80 and the pressure presser 90 is such that it can lead to the movement of the piston 24.

When the required amount of purified water is secured and the water purification process is to be completed, the user separates the fixing ring 28 from the lower outer surface of the pressurized cylinder 10, and the piston 24, the piston rod 26, the pressure support ( 80 and the pressure presser 90 are stored together with the filter assembly 50 and the strainer filter 30.

As mentioned above, when the ratio of the distance from the pivot pin 92 to the connection pin 94 and the distance from the connection pin 94 to the handle 98 is determined to be about 1: 3 to 1:10, Even by pressing the handle 98 with a small force by the lever principle, a large force can be applied to the piston rod 26. For example, if the distance from the pivot pin 92 to the connecting pin 94 is 3 cm and the distance from the connecting pin 94 to the handle 98 is 30 cm, if a force of 5 N is applied to the handle, the piston rod A large compressive force of 50 N is applied to (26).

Such portable water purifiers can be used irrespective of chemical and / or biological pollution and regardless of water sources such as rivers, reservoirs and lakes. In particular, the water purifier according to the present invention can also be used to purify seawater. Generally, the total dissolved solids (TDS) concentration of seawater is known to be about 35,000mg / ℓ, the osmotic pressure of standard seawater is known to reach about 25bar. In addition, in order to produce fresh water by purifying such seawater, it is known that reverse osmosis pressure of about 42 to 60 bar is required. If the ratio of the distance from the pivot pin 92 to the connection pin 94 and the distance from the connection pin 94 to the handle 98 in the water purifier is 1:10, a force that can cause reverse osmosis of about 6 bar As a result, a force of 60 bar can be applied to the pressurization room 22 and the reverse osmosis filter 55, and thus the water purifier can purify the seawater.

Meanwhile, although the pressure support 80 and the pressure presser 90 are configured to operate like scissors in FIG. 1, the pressure support 80 and the pressure presser 90 may be used in the modified embodiment. ) May be modified in various ways. For example, as in the embodiment shown in FIG. 2, a support 80a having a shorter length than the pressure support 80 is provided outside the fixing ring 28 to the outside of the pressure cylinder 10, and the support 80a. And pressure presser 90 may be coupled by connecting pin 94. In this case, the user can hold the pressure cylinder 10 with one hand and operate the support 80a with the other hand.

In addition, the present invention can be modified in various ways without departing from the spirit and essential characteristics thereof, and can be embodied in other specific forms.

For example, in the above description, although the fixed ring 28 is described as a separate member that can be fastened to the pressure cylinder 10, the fixed ring 28 is considered to constitute a part of the pressure cylinder 10 itself. It may be.

On the other hand, in the above description, it has been described that the filter assembly 50 can be connected to the pressure cylinder 10 by the filter connecting pipe 40, the distance between the filter assembly 50 and the pressure cylinder 10 to the maximum By shortening, for example, attaching, the length of the filter connecting pipe 40 can be correspondingly shortened and portability can be improved. Furthermore, it is a matter of course that the filter assembly 50 and the pressure cylinder 10 may be integrally manufactured.

On the other hand, although two check valves 18 and 20 are described as being preferred in the preferred embodiment, at least the outlet side check valve 20 may be omitted in embodiments where this embodiment is modified.

On the other hand, while the filter assembly 50 has been described as having a precipitation filter 54, a reverse osmosis (RO) filter, a carbon filter 56, a ceramic filter 57, such filters One or more of these may optionally be used, and other filters may be used. In particular, a hollow fiber membrane (UF) filter may be used in place of the reverse osmosis 55 filter.

The use of fluidic connection means such as absorber tube 32, filter connector 40 and water bottle connector 60, and whether or not the corresponding connector can be used correspondingly, and various modifications as described above may be adapted to the needs of the application. Catering can be chosen.

Therefore, it should be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
