Recently, there has been a worldwide shortage of drinking water due to population growth and environmental pollution, and interest in water purification technology to obtain quality water is increasing. In particular, in third-world countries that do not have adequate water supply facilities such as Africa and Southeast Asia, many lives are lost due to the severe shortage of drinking water. the current situation.

Moreover, as global warming due to abnormal climate accelerates, desertification that occurs in water-scarce countries is further exacerbating the problem of water shortage. As grazing is carried out, the vicious cycle repeats. Therefore, water, which is essential for human beings, becomes more scarce and water welfare is further deteriorated.

Therefore, in recent years, a portable water treatment device that can be used as drinking water by simply filtering water anywhere has been developed. Most of the products use a membrane filter for water filtration. Due to the nature of the membrane filter, once it is wet and then dried, bacteria proliferate on the membrane. Therefore, in the previous product, the membrane blocks the bacteria proliferating outside the membrane, but there is a problem that the user inhales the bacteria proliferated inside the membrane as it is with water. Therefore, it is recommended to store some products below 4℃.

If water is used as the quality of water provided in countries where water health and sanitation is remarkably low, such as in a water-scarce country, it can cause physical diseases such as food poisoning and atopy, and the conventional water treatment system can be a complete solution. none.

Therefore, the development of a portable advanced water purification device that can be used with confidence so that raw water can be taken as drinking water even in an area that is not properly equipped with water supply facilities, and is formed in a compact size can be carried anywhere even if it is frequently moved, is on the rise.

It can be prevented, and the present invention does not cause a hygienic problem even if the present invention rolls in a user's pocket or bag.

2 to 4, the membrane cartridge 130 into which raw water is introduced through the inlet 110 is configured to remove harmful components such as foreign substances and bacteria contained in the raw water.

The membrane cartridge 130 is shown as a configuration separate from the lower housing 100 according to an embodiment of the present invention, and is presented as a configuration to be fitted into the lower housing 100 . However, the membrane cartridge 130 may be provided integrally with the lower housing 100 or the upper housing 200 . 7 and 8 show a state in which the membrane cartridge 130 is integrally formed with the lower housing 100 .

The membrane cartridge 130 receives raw water through the inlet 110 at the bottom, and filters the raw water inside the membrane cartridge 130 through the filtration membrane 131 .

The filtration membrane 131 is a hollow fiber membrane type, and is formed as a thin pole-shaped membrane. The filtration membrane 131 is a membrane capable of separating a mixture by selectively passing only a specific size or less, and in the present invention, pure water is passed to filter out debris, foreign substances, bacteria, and the like in the water.

The filtration membrane 131 has a daerong shape, and a plurality of pores 132 are formed on the outer circumferential surface. The pores 132 are formed in a fine size and are through holes for filtering foreign substances, allowing pure water to pass through and blocking large-sized debris, foreign substances, bacteria, and the like.

The diameter of a plurality of pores 132 formed on the outer peripheral surface of the filtration membrane 131 is formed with an average size of 0.2 ㎛. Therefore, foreign substances exceeding 0.2 μm cannot pass through the pores 132 and are filtered by the filtration membrane 131 .

In order to pass through the pores 132, a pressure of a certain level or more must be applied. As a means for this, in one embodiment of the present invention, when the cartridge 112 fastened to the coupling 111 is a plastic bottle, the cartridge 112 is pressed to generate water pressure, and the cartridge 112 is pressed to Water is passed through the pores 132 with the generated water pressure.

However, the present invention is not limited thereto, and in the case of the cartridge 112 made of a material other than a plastic bottle, water is supplied into the inside of the filtration membrane 131 through the pores 132 with the intake pressure generated by the user sucking with the suction straw 230 . can be moved

Both ends of the filtration membrane 131 are opened to form a discharge through hole 133 through which water is discharged to the outside of the filtration membrane 131 . That is, as water flows into the inside of the filtration membrane 131 through the pores 132, foreign substances having a size larger than that of the pores 132 are filtered out, and the water introduced into the filtration membrane 131 is filtered through the filtration membrane ( 131) and is discharged to the outside of the filtration membrane 131 through the discharge through-holes 133 at both ends.

The filtration membrane 131 communicates with a lower through hole 212 formed in a lower plate 211 to be described later. In addition, water in the membrane cartridge 130 is discharged only through the lower hole 212 of the lower plate 211 . The lower plate 211 has a closed surface except for the lower through-hole 212 so that water cannot be discharged to any other place except the lower through-hole 212 .

That is, water flows into the membrane cartridge 130 through the water inlet 110 , and the water in the membrane cartridge 130 moves into the inside of the filtration membrane 131 through the pores 132 of the filtration membrane 131 , and the filtration membrane (131) the water inside is discharged to the outside of the filtration membrane 131 through the discharge through-hole 133, the discharge through-hole 133 is in communication with the lower through-hole 212 of the lower plate 211, the lower through-hole (212) It will be discharged to the outside of the membrane cartridge 130 through the.

The discharge through-holes 133, which are both ends of the filtration membrane 131, are in communication with the lower through-holes 212 of the lower plate 211, so they are formed in a 'U' shape. Accordingly, the discharge through-hole 133 is located at the upper end of the membrane cartridge 130 , and the pores 132 are located below the discharge through-hole 133 .

The water introduced into the filtration membrane 131 through the membrane cartridge 130 moves upward along the longitudinal direction of the filtration membrane 131 and exits through the discharge through-hole 133, and into the ceramic ball chamber 210. is brought in

7 and 8 are diagrams illustrating an embodiment capable of backwashing the portable advanced water purification apparatus of the present invention.

7 and 8, the membrane cartridge 131 is shown to be integrally formed with the lower housing 100, but is configured separately so that the membrane cartridge 131 is located inside the lower housing 100. It can also be inserted.

In addition, although the upper plate 213 and the lower plate 211 are shown to be integrally formed in the ceramic ball chamber 210 , the backwash adapter 140 may be coupled without the ceramic ball chamber 210 . If the outer peripheral surface of the membrane cartridge 130 and the backwash adapter 140 are screwed together without the ceramic ball chamber 210 , the height of the backwash adapter 140 can be reduced. Hereinafter, a situation in which the ceramic ball chamber 210 is integrally formed will be described.

If the advanced water purification device of the present invention is continuously used, the pores 132 of the filtration membrane 131 are clogged with foreign substances, etc., so that the filtration efficiency is lowered and the pressure required for water to pass through the pores 132 is further increased.

At this time, backwashing is performed to remove foreign substances covering the pores 132 by flowing water in the opposite direction, and a backwashing adapter 140 is provided for backwashing. Water flows into the inside of the filtration membrane 131 through the lower through-hole 212 of the lower plate 211 using the backwash adapter 140, and through the pores 132 in the filtration membrane 131 By discharging to the outside, foreign substances attached to the pores 132 are detached.

An adapter coupling screw 134 is formed on the outer periphery of the membrane cartridge 130 , and a lower coupling hole 141 fastened to the adapter coupling screw 134 is formed in the lower portion of the backwashing adapter 140 , and backwashing An upper coupling hole 142 coupled to the cartridge 112 is formed on the upper portion of the adapter 140 .

Looking at the flow of water during the backwashing process, in a state in which the lower coupling hole 141 is coupled to the adapter coupling screw 134 and the cartridge 112 is coupled to the upper coupling member 142, the cartridge 112 ), the water of the cartridge 112 passes through the ceramic ball chamber 210 through the through-hole communicating the upper coupler 142 and the lower coupler 141, and the lower plate 211 It flows into the inside of the filtration membrane 131 through the lower through-hole 212 .

As the water inside the filtration membrane 131 passes through the pores 132 by water pressure, foreign substances adhering to the pores 132 may be desorbed.

Therefore, the purification efficiency of the filtration membrane 131 is restored, so that water can pass through the pores 132 even with a small water pressure, and the pressure that the user must apply is reduced, so that water can be conveniently drunk.

2 to 3 and 5, the ceramic ball chamber 210 is disposed in the upper housing 200, and the water filtered in the membrane cartridge 130 is configured to further improve the water quality. .

In addition, the ceramic ball chamber 210 is provided in a cylindrical shape with a hollow inside, and the circular side has a structure in which the lower plate 211 and the upper plate 213 are coupled and is sealed.

That is, the ceramic ball chamber 210 can be introduced into the inside only through the lower through-hole 212 of the lower plate 211 , and the ceramic ball chamber 210 only through the upper through-hole 214 of the upper plate 213 . ) can be discharged to the outside, and the side has a structure in which the lower plate 211 and the upper plate 213 are coupled, so that inflow and discharge of water to the side is impossible.

A plurality of water quality improving agents 215 are filled in the ceramic ball chamber 210 . The water quality improving agent 215 is made of a ceramic ball, and the direction in which the water quality is improved can be set according to the material of the ceramic ball. For example, when the water quality improving agent 215 is formed of activated carbon, it is possible to improve taste and smell by removing soluble foreign substances such as phosphorus and nitrogen in water while in contact with water. However, the water quality improving agent 215 may be variously formed from conventional materials widely used for the purpose of improving water quality, such as illite ball, tourmaline ball, etc., in addition to activated carbon, and according to the user's preference and taste, conventional materials can be variously transformed into

2 to 3 and 5 , water with improved water quality in the ceramic ball chamber 210 is introduced into the sterilization chamber 220 through the upper through-hole 214 .

The sterilization chamber 220 sterilizes bacteria in the water flowing inside the sterilization chamber 220 by irradiating ultraviolet rays from the UV-C LED 226 .

The support plate 224 is disposed to slightly cover the upper plate 213 , and is slightly spaced apart from the upper through-hole 214 so as not to cover the upper through-hole 214 .

A sterilization inlet 225 is formed at one side of the support plate 224 so that water discharged through the upper through-hole 214 may be introduced into the sterilization chamber 220 through the sterilization inlet 225 .

In addition, the support plate 224 is disposed to be slightly inclined from the upper portion of the upper plate 213 . The inclined direction is inclined upward toward the sterilization inlet 225 .

The water discharged through the upper hole 214 of the upper plate 213 is first blocked by the support plate 224, and is guided toward the sterilization inlet 225 by the inclination of the support plate 224. . Therefore, it is introduced into the sterilization chamber 220 only through the sterilization inlet 225 .

The guiding wall 222 vertically disposed on the support plate 224 is configured to divide the space inside the sterilization chamber 220 to form a water flow path 300 .

A passage hole 223 is formed at the upper end of the guide wall 222 to allow water to pass through the passage hole 223 to the opposite side of the guide wall 222 .

The flow path 300 is formed by the guiding wall 222 , and the water flowing along the flow path 300 flows into the sterilization chamber 220 through the sterilization inlet 225 and rises. will do The flow rising from the sterilization inlet 225 is referred to as an ascending direct current section 310 .

Water rising through the rising direct current section 310 is close to the UV-C LED 226 disposed on the upper end of the sterilization chamber 220, and is exposed to ultraviolet rays irradiated from the UV-C LED 226. .

At the upper end of the ascending direct current section 310, water passes to the opposite side of the guiding wall 222 as it rotates around the passage hole 223. (320).

The water passing through the curved section 320 is changed from an ascending direction to a descending direction in the flow direction, and is strongly exposed to ultraviolet rays irradiated from the UV-C LED 226 to sterilize bacteria in the water. .

Water exits from the curved section 320 and descends from the opposite side of the guiding wall 222 toward the straw inlet 231 of the suction straw 230 . This flow is referred to as a descending DC section 330 .

The water flowing through the descending DC section 330 gradually moves away from the UV-C LED 226 irradiating the UV rays.

The water flow path 300 formed by the guiding wall 222 is formed of an ascending DC section 310 , a curved section 320 , and a descending DC section 330 .

And, since the sterilization inlet 225 introduced into the sterilization chamber 220 and the straw inlet 231 discharged to the outside of the sterilization chamber 220 have the guiding wall 222 interposed therebetween, the sterilization chamber ( The flow path 300 introduced and discharged from 220 may be formed to be long, and the residence time of the water flowing along the flow path 300 increases in the sterilization chamber 220 and the ultraviolet rays are uniformly irradiated.

The water passing through the rising DC section 310 is gradually closer to the UV-C LED 226 and closest to the UV-C LED 226 while passing through the curved section 320, and the falling DC section ( 330) and gradually away from the UV-C LED 226.

The UV-C LED 226 emits UV light to both water rising along the ascending DC section 310 , water passing through the meandering section 320 , and water descending along the descending DC section 330 . investigate Therefore, even if water flows through the sterilization chamber 220 while maintaining the flow, it is sufficiently exposed to ultraviolet rays and sterilization treatment can be performed. In addition, the flow path 300 is formed long enough so that the residence time in the sterilization chamber 220 is increased to a time sufficient for sterilization, and ultraviolet rays are evenly irradiated to the passing water so that the user can drink with confidence. Sterilization is carried out.

The suction straw 230 communicating with the inside of the sterilization chamber 220 is a configuration in which the user puts his mouth on and sucks water. A straw inlet 231 is formed at the lower end of the suction straw 230, and a straw outlet 232, which is a portion in contact with the user's oral cavity, is formed at the upper end.

The straw inlet 231 is formed at a lower position than the passage hole 223 to form the descending direct current section 330 . Since the flow of water in the sterilization chamber 220 moves along the path of the sterilization inlet 225 - the passage 223 - the straw inlet 231, the flow from the passage 223 to the straw inlet 231 is lowered. it can be done

Since the water flowing into the suction straw 230 through the straw inlet 231 is sufficiently sterilized by the UV-C LED 226 while moving along the flow path 300 in the sterilization chamber 220, bacteria, etc. It is removed to form water suitable for drinking, so the user can safely drink water.

2 to 3 and 5, an upper cap 240 is disposed on the upper end of the upper housing 200 to protect the UV-C LED 226, and An operation button 241 is provided on one side.

In addition, a battery 250 for supplying power to the UV-C LED 226 is disposed inside the upper housing 200 , and a controller 260 for controlling the power of the battery 250 is provided. The control unit 260 is provided with a terminal connected to a charging cable for charging the battery 250 . When the battery 250 is discharged, it can be charged through a terminal.

By the operation button 241, the control unit 260 may control to supply the power of the battery 250 to the UV-C LED 226 and to stop the supply of power.

Therefore, the UV-C LED 226 minimizes the consumption of the battery 250 by preventing unnecessary power consumption by allowing the user to operate only when water is taken. can

Hereinafter, with reference to FIGS. 4 to 5, the operation of the portable advanced water purification apparatus according to the present invention and the flow of water will be described with reference to an embodiment.

When the user wants to take water, he presses the operation button 241 to control the power of the battery 250 to be supplied to the UV-C LED 226 . The UV-C LED 226 receives power from the battery 250 and irradiates UV rays downward.

After removing the lower cap 120, when raw water is contained in a cartridge 112 such as a PET bottle as shown in FIG. The cartridge 112 is pressed at the same time as it is tilted so that it can be introduced into the advanced water purification device.

Alternatively, when raw water is stagnated in an unexpected container or water puddle as shown in FIG. 6(b), insert the straw 113 to communicate with the inlet 110 and allow the straw 113 to settle in the water, and then the user Suction through the suction straw (230).

Raw water flows into the membrane cartridge 130 through the inlet 110 , and water flows into the filtration membrane 131 through the pores 132 of the filtration membrane 131 in the membrane cartridge 130 . At this time, foreign substances and bacteria having a large particle size do not pass through the pores 132 and are filtered.

The water inside the filtration membrane 131 is discharged through the discharge through-hole 133 of the filtration membrane 131 , and flows into the ceramic ball chamber 210 through the lower through-hole 212 connected to the discharge through-hole 133 .

As the water comes into contact with the water quality improving agent 215 filled in the ceramic ball chamber 210 , the soluble foreign matter is removed to improve water and odor. Depending on the material of the water quality improving agent 215, the improvement direction of the water quality may be variously changed.

Water with improved water quality in the ceramic ball chamber 210 is discharged from the ceramic ball chamber 210 through the upper through-hole 214, moves along the slope of the support plate 224, and then passes through the sterilization inlet 225 to the sterilization chamber. (220) is introduced into the interior.

In the sterilization chamber 220, the water rises along the rising direct current section 310, is exposed to UV light as it approaches the UV-C LED 226, passes through the passage hole 223, and the flow direction is changed. It is most strongly exposed to UV light while moving in the curved section 320 , and moves along the descending DC section 330 while being irradiated with UV light from the UV-C LED 226 .

As the water is continuously and continuously exposed to UV light by the UV-C LED 226 as it moves along the flow path 300 , the sterilization treatment is performed while maintaining the flow.

It moves to the suction straw 230 through the straw inlet 231, which is the lower end of the passage 223, and is discharged to the outside of the advanced water purification device of the present invention through the straw outlet 232, and the user takes water.

After the water intake is finished, the power of the battery 250 is stopped from being supplied to the UV-C LED 226 through the operation button 241 .
