Description

Portable water purifier {A portable water purifier}

The present invention provides a rational structure of a portable bucket and a filter cartridge for attaching a military water bottle, so that various natural waters that may cause health hazards in outdoor leisure activities or military operations can be purified and safely ingested as drinking water. For that purpose.

So far, water purifiers and filter cartridges have been developed so that natural water can be used as safe drinking water without any restriction on spatial use. Therefore, drinking water is not processed in military training or outdoor activities. Many cases of using natural water as drinking water after simple disinfection treatment may cause waterborne diseases and various health hazards. In addition, even when the installed type water purifier is installed in a group facility such as a school, many problems of hygiene may be caused by the contamination of the water purifier itself.

Therefore, small and easy-to-use portable water purifiers can be used to safely purify the harmful substances in the natural water, which may be contaminated when using drinking water in military training, outdoor activities, group facilities, etc. The filter cartridge for water bottle attachment was developed.

Currently, the water purifier that is being developed and distributed is large capacity, expensive, and the space use is extremely limited for installation in home or group facilities. Therefore, the development of portable water purifier and filter cartridge that can purify natural water during outdoor activities is urgently needed.

Therefore, the present invention removes the physical, chemical and biological contaminants contained in the natural water as a portable water purifier and a water filter filter cartridge with a small size by using various media used in the filter cartridge. The present invention relates to the development of a portable water purifier and a filter cartridge for water tank attachment having a function capable of purifying with water suitable for use.

Currently, the water purification method of installed type water purifier is reverse osmosis membrane method, hollow fiber membrane method, ion exchange resin method, activated carbon adsorption / filtration method, electrolytic ion method, elvan method, etc. These water purification methods use a variety of media mixed rather than using a single media, and the chlorine disinfectant is used to sterilize the causative agents of waterborne infectious diseases in natural water. Methods are known.

The water treatment method using reverse osmosis membrane is a filtration of ions having high molecular weight such as various salts by using a semi-permeable membrane, which is widely used for the production of distilled water, ultrapure water, desalination of brine, and the removal of various mineral components in water. Because of the high filtration resistance at the time, separate power is required for high pressure and high vacuum. Since the air gap of membrane is very small, membrane fouling such as clogging due to turbidity of raw water is frequent, and the filtration resistance increases accordingly. This is followed by an increasing problem.

The water purification method using the hollow fiber membrane is almost the same as the water purification method using the reverse osmosis membrane, and filtration resistance and clogging are pointed out as problems.

Water purification treatment method using ion exchange resin is not used alone but mixed with other media. Its purpose is to remove ionic substances in water. It is a disadvantage that the dissolution of.

Adsorption filtration method using activated carbon is the typical method of water purifier for installation by using adsorption of various shapes of activated carbon to remove odor, color, organic and inorganic substances in water.

Electrolytic ions have limitations in the removal of ionic substances in such a way that water is ionized by electrolysis, negative ions are collected at the anode, positive ions are collected at the cathode, and ionic substances are removed from the treated water. The disadvantage is that it does not target the removal of ionic substances.

The method using elvan is a water purification method using the adsorption characteristics of porous elvan and the far-infrared radiation characteristics of elvan. Its disadvantage is that the elvan has little adsorption performance and the effect of far infrared rays on the water quality is not known. Often used.

The method of using chlorine disinfectant is a method used in the movement of outdoor activities, which causes a strong irritating smell and taste peculiar to chlorine and does not remove contaminants in natural water other than bacteria causing waterborne infectious diseases.

The purpose of the present invention is not the conventional fixed installation type water purifier, but the small capacity that is easy to carry, so there is no space use restriction, and the characteristics of the development of portable water purifier and water filter filter cartridge with water purification function similar to the previously developed installation type water purifier .

In addition, the present invention provides a filter cartridge for a portable water purifier and a water bottle attachment filter cartridge which minimizes the filter cartridge so that the filter cartridge can be purified by human oral suction power without external power in the process of purifying natural water and has an effective water purification ability with an optimal filter media arrangement. Development.

The portable water purifier of the present invention for purifying natural water with water that meets drinking water quality standards can be detached from the filter cartridge, the lid part with the suction tube and the lid on the upper part, the non-woven filter for pretreatment, silver treatment bioceramic, silver activated carbon It is composed of a filter unit filled with fabric activated carbon, ion exchange resin, fibrous activated carbon, granular activated carbon, and a fine post-treatment polyethylene filter, and a body portion that can be adjusted in size and contracted and relaxed as needed.

In the present invention, the military or general water bottle attachment filter cartridge is composed of a water inlet connection part connected to the screw cap on the top of the water bottle and a filter cartridge part filled with the same filter medium as the filter cartridge built in the portable water purifier and attached to a damper for external air control. .

Since the negative pressure corresponding to the suction pressure is formed in the water tank when the water is sucked in order to purify the natural water put in the water tank, in order to offset the negative pressure, the portable water purifier made a vent to allow external air to flow into the screw portion of the body. Ventilation dampers were installed in the filter cartridge for the water bottle attachment on the outer wall of the filter cartridge empty space not filled with the filter medium so that the valve of the water bottle cap can be inserted.

The technical problem to be solved by the present invention is to ensure that a small amount of filter cartridges can obtain appropriate filtered water by oral suction force, and that the filter cartridge of the present invention can filter natural water by oral suction force at the filtration speed of physical, chemical and biological contamination. It has the function to completely remove the substances, and the amount of filtration is determined so that the filter cartridge can be replaced after use within the filter limit by various media in the filter cartridge. It is to prevent the health risks caused by using natural water as safe drinking water that is safe and suitable for drinking water quality standards.

1 is a cross-sectional view of a portable water purifier combined with a filter cartridge 3 and a water intake port 2a, a water intake cover 2b, and a water intake cover 2 in a water bottle 1.

The material of the water bottle 1 is made of synthetic resin, and as shown in Fig. 1, the uneven bottle pleated wall 1a is placed on the body, and when used as an empty bottle, it can be compressed up and down to reduce its volume. It is to expand the capacity.

Lid 2b is a constitution of a general screw type lid and has an integrated shape in which the inlet 2a and the lid 2 are coupled to the top. The lid is opened and closed to take in through the inlet 2a.

The filter cartridge 3 is formed of synthetic resin, has a threaded portion 3c protruding outward on the upper side, and contains filter media 3d to 3k on the inner side.

Examples of the filter media 3d to 3k include a pre-treatment nonwoven fabric filter 3k, a silver-treated bio ceramic 3j, a silver activated carbon 3i, a cloth activated carbon 3h, an ion exchange resin 3g, a fiber activated carbon 3f, and granular activated carbon 3e, as shown in FIG. A polyethylene filter for processing 3d or the like can be applied and filled, and each layer can be separated as a fiber filter between the respective media. In addition to the above-described filter media 3d to 3k, other filter media may be appropriately incorporated depending on the intended use.

On the other hand, the cover 2 is covered on one side of the lid portion 2b, and when not in use, the cover 2 is covered on the lid portion 2b so that it can be kept clean.

If clean water is required outdoors, fill the water bottle 1 with natural water that requires water, and remove the cover 2 when drinking water while the lid 2b with the filter cartridge 3 is incorporated. If the water is sucked into the mouth, the water contained in the water bottle is purified through the inlet hole 3b of the filter cartridge 3 through the filter media 3d to 3k in order, and then sucked into the mouth through the inner tube of the outlet hole 3a and the intake port 2a.

Therefore, when the filter cartridge 3 of the present invention is coupled to the water bottle 1 and sucked using the intake port 2a, the purified water can be immediately consumed immediately and can be effectively used as an outdoor or portable filter.

The water bottle 1 can be manufactured not only in a cylindrical shape but also in a flexible flat tube type.

4 shows another embodiment of the present invention, in which the inlet connecting pipe 5a and the inlet 5 are coupled to the water bottle 4. The water bottle 4, the lid 4a, the inlet connection cap 4b and the inlet connector 5a at the top of the lid are used without changing the current product.

The filter cartridge 6 has the same filter medium as the cartridge 3 of FIG. 3 described above, but has an empty chamber 61 and an aeration device at the upper portion thereof, so that the filter cartridge 6 can be easily coupled to a bottle, such as a military water bottle. The water bottle cartridge 6 is made of synthetic resin and has a threaded portion protruding outward and an empty space 61 into which a valve attached to the inside of the lid can be inserted. In particular, on the outer wall of this chamber 61, a negative pressure corresponding to the suction pressure during suction is generated in the water tank. A separate ventilation damper 6c is provided for offsetting the damper 6c, which uses rubber with high flexibility. In addition, various filter agents 3d to 3k are contained inside.

Filter Media to be Used 3d to 3k The same filter media embedded in FIG. 3 can be used, and other filter media can be appropriately incorporated depending on the intended use in addition to the above composition.

The inlet port connecting cap 4b, the inlet port 5a, and the inlet port 5 are attached to the upper portion of the lid 4a.

The inlet connecting pipe 5a can be inserted into the connection part of the inlet port 5 to lengthen or shorten it according to a use.

The present invention of the above configuration is always connected to the water bottle even when carrying the filter cartridge 6, and is characterized in that it is easy to carry because only the intake port 5, the intake connector 5a and the intake connection cap 4b are stored in the pocket of the water bottle case side. .

The field to which the present invention can be applied can be widely applied to general purpose water bottles, outdoor water bottles, portable water bottles and military water bottles of industrial workers.

For example, if water purification is required for outdoor training or exhibition, load a natural water requiring water into a portable water bottle 4, such as a military water bottle, and then combine the filter cartridge 6 with the water bottle lid 4a and the water intake port 5 and the water intake connector 5a. When the water inlet port 4b is connected to the water bottle cap 4a, the portable water bottle 4 is turned upside down, and the water inlet 5 is sucked into the mouth and sucked in. The built-in water passes through the inlet 6b of the filter cartridge 6 through the filter medium 3d to 3k. After it is made, suction is made into the mouth through the inner tube of the outlet hole 6a and the intake port 5.

Therefore, when the filter cartridge 6 of the present invention is combined with the inlet connecting cap 4b, which is combined with the inlet 5 and the inlet connecting tube 5a, the inhalation using the inlet 5 can immediately drink clean purified water immediately. As a water purifier for military water can be used very effectively.

As indicated above, the present invention is a device for treating natural or ground water that may be contaminated when drinking water is difficult to drink during general leisure or military training, school life and outdoor activities. It is effective in preventing health hazards by eliminating waterborne diseases and various contaminants contained in these contaminated raw water.

In case of portable water purifier, the size of the body can be adjusted so that it can be shrunk and relaxed as needed. In addition, the chlorine disinfectant currently used when using a filter cartridge for water bottle attachment for military use can kill the causative agent of waterborne infectious diseases, which is a biological pollutant. When the filter cartridge of the present invention is installed in a military water bottle, it may have a good water purification function capable of excellent purification of physical, chemical and biological contaminants in natural water.
