Features.

(1) Raw water storage container The raw water storage container 1 is a container in which raw water is stored. The raw water storage container 1 is a container having a bottom portion 101 and a side wall 102 erected at a predetermined height from the periphery of the bottom portion 101 and having an opening 103 formed above. The inner diameter of the opening 103 of the raw water storage container 1 is preferably formed slightly larger than the inner diameter of the bottom 101. The planar shape of the bottom 101 is not particularly limited, and examples thereof include a circular shape and a rectangular shape. Examples of the shape of the raw water storage container 1 include a cylindrical, polygonal, and conical bottomed hollow shape. The material of the raw water storage container 1 is preferably made of resin, and may be a resin composed of a soft segment and a hard segment. Either a thermoplastic resin or a thermosetting resin can be used, but it is preferable to use a thermoplastic resin in order to improve moldability. In addition, polystyrene (PS), acrylonitrile butadiene styrene (ABS), polypropylene (PP), etc., should be used as the resin species, and it increases the strength and impact resistance required for raw water storage containers and ensures excellent transparency. In order to reduce material costs, it is preferable to use polystyrene.

(2) Lid The portable water purifier of the present invention has at least one lid that closes the opening 103 of the raw water storage container 1. The lid may be formed of a single layer or may be formed of two or more layers. In the embodiment shown in FIG. 1, the first lid 2 is provided as an inner lid that closes the opening 103 of the raw water storage container 1, and the second lid 3 covers the upper side of the first lid 2. It is provided as. When the first lid 2 closes the opening 103 of the raw water storage container 1, the raw water storage unit 4 is formed. The planar shape of the first lid 2 is not particularly limited as long as it is a shape that engages with the opening 103 of the raw water storage container 1. In the embodiment shown in FIG. 1, the first lid 2 and the second lid 3 are shown as separate bodies, but they may be integrally formed. The material of the first and second lids is preferably made of resin, and may be a resin composed of a soft segment and a hard segment. Either a thermoplastic resin or a thermosetting resin can be used, but it is preferable to use a thermoplastic resin in order to improve moldability. As the resin type, acrylonitrile butadiene styrene (ABS), polypropylene (PP), polyacetal (POM) or the like is preferably used. In order to improve the bending resistance, improve the appearance, and reduce the material cost, It is preferable to use polypropylene.

(3) Raw Water Storage Unit The portable water purifier of the present invention has the raw water storage unit 4 formed by closing the opening 103 of the raw water storage container 1 with a lid. The raw water storage unit 4 stores raw water such as tap water and well water. The capacity (S1) of the raw water storage unit 4 is preferably 0.5L or more, more preferably 1L or more, and further preferably 1.5L or more. If the capacity | capacitance (S1) of the raw | natural water storage part 4 is 0.5L or more, when going out, raw | natural water will not be lost early, and the replenishment frequency of raw | natural water will decrease. Moreover, from a viewpoint of improving portability without increasing the size, the capacity (S1) of the raw water storage unit 4 is preferably 4L or less, more preferably 3L or less, and even more preferably 2.5L or less.

(4) Pressurizing means The portable water purifier of the present invention has a pressurizing means 5 for pressurizing the raw water storage unit 4. By pressurizing the raw water with the pressurizing means 5, the raw water can be passed through the purification means 6 in a short time. Examples of the pressurizing method include pressurization by air pressure or water pressure, and pressurization by air pressure is preferable. As the pressurizing means 5, a pump is preferably used. The pump can be a manual pump with manual driving force or an electric pump using electric power as the driving force, but it eliminates the problem of miniaturization, weight reduction, cost reduction and battery exhaustion of portable water purifiers. Therefore, it is better to use a manual pump. In addition, a positive displacement pump that sends out fluid by changing the volumetric space of a space having a constant volume, a turbo pump that sends out fluid by rotating an impeller in a case, etc. can be used. In order to enable sufficient fluid delivery, a positive displacement pump, that is, a manual and positive displacement pump may be used. As a positive displacement pump, a bellows type pump that changes the bellows-shaped volume space to send fluid, a piston type pump that sends and receives fluid by reciprocating a piston placed in the cylinder, and a plan that sends and receives fluid by reciprocating a plunger Jar type pumps, diaphragm type pumps that move the diaphragm to move fluids, etc. can be used, but in order to reduce the size, weight, cost, and manual operation of portable water purifiers, bellows type pumps Therefore, it is preferable to use a manual and bellows type pump. As long as the pressurizing means 5 is installed so as to pressurize the raw water storage unit 4, it may be installed at any location of the portable water purifier 10 </ b> A, for example, the lid 2 and the side wall 102 of the raw water storage container 1. Alternatively, it may be installed inside the raw water storage container 1. In addition, you may make it the structure which introduces the fluid pressurized from the outside instead of using a pump. Air or water can be used as the pressurized fluid, but since it can be used in many places, it is preferable to use tap water as the fluid. When tap water is used, supply of raw water to the raw water storage unit and pressurization can be performed simultaneously by supplying tap water to the raw water storage unit in a state where the raw water storage unit is sealed. In addition, when it is set as the structure which introduces the fluid pressurized from the outside, since it cannot pressurize, when a portable water purifier is taken out outdoors etc., it is more preferable to use a pump.

(5) Purifying means The portable water purifier of the present invention includes a purifying means 6 that is connected to the raw water storage unit 4 and purifies the raw water. As said purification | cleaning means 6, what is equipped with an adsorbent, a hollow fiber membrane, a sterilization ceramic etc. is preferable, for example. By providing an adsorbent, a hollow fiber membrane, a sterilizing ceramic, and the like, organic substances such as chlorine, heavy metals, trihalomethane, bacteria, microorganisms, and other foreign matters contained in the raw water can be removed.

  Examples of the adsorbent include a powder adsorbent, a granular adsorbent granulated from the powder adsorbent, and a fibrous adsorbent. Examples of such adsorbents include natural product-based adsorbents (natural zeolite, silver zeolite, acidic clay, etc.), synthetic-based adsorbents (synthetic zeolite, bacterial adsorption polymer, phosphate rock, molecular sieve, silica gel, silica alumina gel, etc. Inorganic adsorbents, powdered activated carbon, granular activated carbon, fibrous activated carbon, block activated carbon, extruded activated carbon, molded activated carbon, molecular adsorption resin, synthetic granular activated carbon, synthetic system Well-known materials such as fibrous activated carbon, ion-exchange resin, ion-exchange fiber, chelate resin, chelate fiber, superabsorbent resin, superabsorbent resin, oil-absorbent resin, and oil-absorbent organic adsorbents are included. Among these, activated carbon having excellent adsorptive power for organic compounds such as residual chlorine, mold odor, and trihalomethane in raw water is preferably used.

  Fibrous activated carbon has a large bulk volume, low water flow resistance, and a large bulk volume, which increases the surface area per volume, resulting in excellent initial purification performance, but degradation in purification performance over time. Is big. The length of the fibrous activated carbon is preferably 0.1 mm or more, more preferably 0.2 mm or more, further preferably 0.3 mm or more, preferably 1 mm or less, more preferably 0.8 mm or less, and further 0.6 mm or less. preferable. If it is less than 0.1 mm, it is too small and tends to cause black powder during use. On the other hand, when it is larger than 1 mm, an excessive gap is likely to be generated in the mixture, the density of the entire mixture is reduced, and the filling amount tends to be insufficient.

  Since the granular activated carbon has a small bulk volume and a large water flow resistance, the initial purification performance is inferior to the fibrous activated carbon, but the degradation of the purification performance with the passage of use time is small. The particle size of the granular activated carbon is preferably between 40 mesh pass and 200 mesh pass. When the 40 mesh is not passed, the granular activated carbon becomes large, the ratio of the surface area to the volume becomes small, and the contact efficiency with water is lowered, so that the purification performance is insufficient. Further, 50 mesh pass or more is preferable, and 60 mesh pass or more is particularly preferable. Further, if a mesh larger than 200 mesh (for example, 250 mesh) is passed, the granular activated carbon is too small, and black powder is likely to be generated during use. Therefore, 140 mesh path or less is further preferable, and 120 mesh path or less is particularly preferable.

  From the viewpoint of enhancing the purification performance per hour, it is preferable to use fibrous activated carbon. Moreover, it is preferable to use granular activated carbon from a viewpoint which suppresses the fall of the purification performance by progress of use time. It is desirable to use fibrous activated carbon and granular activated carbon in combination in order to increase the initial purification ability with fibrous activated carbon and to maintain purification performance over a long period of time with granular activated carbon. As for the mixing ratio when used in combination, the mass ratio of fibrous activated carbon to granular activated carbon (fibrous activated carbon / granular activated carbon) is preferably in the range of 0.3 to 50. If the mixing ratio is less than 0.3, the initial purification performance tends to be insufficient, and if it exceeds 50, the purification performance tends to deteriorate due to long-term use. The mixing ratio is more preferably 1 or more, further preferably 5 or more, and particularly preferably 10 or more. Moreover, 30 or less is more preferable and 20 or less is more preferable.

  The purification means 6 preferably includes a sterilizing material having a sterilizing effect, such as a sterilizing ceramic, in addition to the adsorbent. Hygiene can be further enhanced. Bactericidal ceramics are made by adsorbing silver or copper, etc. on the surface of a mixture of zinc phosphate, montmorillonite, etc. mixed with calcium phosphate and sintered in granular or pellet form. Sterilize and release metal ions to sterilize or sterilize harmful bacteria in the water, thereby detoxifying the water quality.

  The purification means 6 may include a hollow fiber membrane. The hollow fiber membrane filters and removes particulates of 0.1 μm or more containing microorganisms and bacteria. Various types of porous and tubular hollow fiber membranes can be used as the hollow fiber membrane, such as cellulose, polyolefin (polyethylene, polypropylene), polyvinyl alcohol, ethylene / vinyl alcohol copolymer, polyether, polymethacrylate. Made of various materials such as methyl acid (PMMA), polysulfone, polyacrylonitrile, polytetrafluoroethylene (Teflon (registered trademark)), polycarbonate, polyester, polyamide, aromatic polyamide Can be used. Among these, considering the handleability and processing characteristics of the hollow fiber membrane and the fact that it can be incinerated at the time of disposal, polyolefin-based hollow fiber membranes such as polyethylene and polypropylene are preferred.

  The purification means 6 is preferably a cartridge in which an adsorbent such as activated carbon is molded into a predetermined shape. Since the purifying means 6 is a cartridge, the replacement becomes easy when the purifying performance is deteriorated. At the time of molding, a binder such as a thermoplastic resin or a thermosetting resin may be used. The shape of the purification means 6 is not particularly limited, and examples thereof include a hollow cylindrical shape, a disk shape, or a columnar shape, and a hollow cylindrical shape is preferable. If the purifying means 6 is a hollow cylindrical cartridge, when raw water permeates through the cartridge, water concentrates on only a part of the adsorbent and the water purifying ability is reduced early, so-called water supply (Mizumichi) phenomenon. Occurrence can be suppressed. The purification means comprising a cartridge formed into a hollow cylindrical shape may use the inside of the cylinder as a raw water flow path, the outside of the cylinder as a water purification flow path, the outside of the cylinder as a raw water flow path, and the inside of the cylinder as a water purification flow path. It is good. When a hollow fiber membrane is used as the purification means 6, it is preferable to use a cartridge in which the hollow fiber membrane is filled in the casing.

(6) Purified water storage means The portable water purifier of the present invention includes a purified water storage section 7 for storing the purified water purified by the purification means 6. The capacity (S2) of the purified water storage unit is preferably 100 mL or more, more preferably 150 mL or more, further preferably 200 mL or more, preferably 300 mL or less, more preferably 250 mL or less, and further preferably 200 mL or less. If the capacity of the purified water storage unit is small, the amount of water discharged at one time is reduced. Moreover, when the capacity | capacitance of a purified water storage part is large, it will become easy to generate | occur | produce water discharge (no drinking). As a result, the storage period of purified water may become longer.
The material of the purified water storage section is preferably made of resin, and may be a resin composed of a soft segment and a hard segment. Either a thermoplastic resin or a thermosetting resin can be used, but it is preferable to use a thermoplastic resin in order to improve moldability. As the resin type, polystyrene (PS), acrylonitrile butadiene styrene (ABS), polypropylene (PP), etc. are preferably used, ensuring the strength required for the water purification storage and excellent transparency, and the material cost. In order to suppress this, it is preferable to use polystyrene.

  The ratio (S2 / S1) of the capacity (S2) of the purified water storage part and the capacity (S1) of the raw water storage part is preferably 0.03 or more, more preferably 0.05 or more, and further preferably 0.08 or more, 0.5 or less is preferable, 0.3 or less is more preferable, and 0.2 or less is more preferable. If the ratio of the capacity (S2) of the purified water storage unit and the capacity (S1) of the raw water storage unit is within the above range, the replenishment frequency of the raw water can be reduced, and the remaining water discharge is less likely to occur.

(7) Water discharging means The portable water purifier of the present invention has water discharging means 8 for discharging purified water from the purified water storage section 7. Examples of the water discharge means include a water discharge pipe communicating with the purified water storage unit 7, a water discharge port formed integrally with the purified water storage unit 7, and the like. For example, the water discharge pipe may be detachably coupled to the water purifier or the purified water storage unit 7. In addition to the water discharging means, an opening / closing means may be provided integrally with the water discharging means, between the water discharging means and the purified water storage unit, or downstream of the water discharging means (water discharge opening side). The opening / closing means can be an opening / closing valve or a closing member that is detachably disposed at the water discharge opening. For example, the closing member is a cap member that is detachably disposed at the water discharge opening by a screw function. Can do. By providing the opening / closing means, it is possible to prevent the purified water from being discharged without the user's intention when the portable water purifier of the present invention is carried or overturned.

  It is preferable that the portable water purifier of the present invention further includes a decompression unit that reduces the pressure of the raw water storage unit 4. By providing the pressure reducing means, when the raw water storage unit 4 is excessively pressurized, the pressure of the raw water storage unit 4 can be reduced. The decompression means is not particularly limited as long as the raw water storage section 4 under pressure can be returned to the atmospheric pressure, and examples thereof include an air vent valve and an air vent device.

  In the portable water purifier of the present invention, even when the raw water storage unit 4 is not pressurized by the pressurizing unit 5, the raw water is purified by its own weight, and the obtained purified water stores the purification unit 6. , It may flow into the purified water storage unit 7. If the purified water is stored in the purification means storage section and the purified water storage section 7 and left for several days, bacteria and microorganisms may propagate, which is not hygienic. Therefore, in the present invention, it is preferable to prevent the purified water purified by the dead weight of the raw water from flowing into the purification means storage unit and the purified water storage unit 7. From such a viewpoint, it is preferable that the raw water connection port 210 where the purification unit 6 connects to the raw water storage unit 4 is located below the purified water connection port 703 where the purification unit 6 connects to the purified water storage unit 7. That is, in the purification means 6, it is preferable that the flow of raw water treatment is from below to above. This is because if the raw water treatment flow of the purification means 6 is changed from the upper side to the lower side, the raw water is easily purified by its own weight and easily flows into the purified water storage unit 7.

  In the portable water purifier of the present invention, the bottom 707 of the purified water storage unit 7 is preferably located above the bottom 101 of the raw water storage unit 4. As long as the surface of the raw water stored in the raw water storage unit 4 is located below the bottom 707 of the purified water storage unit 7, even if the raw water is purified by its own weight, the purified water flows into the purified water storage unit 7. It is suppressed. Moreover, it is more preferable that the bottom 707 of the purified water storage unit 7 is positioned above the upper part (for example, the first lid 2) of the raw water storage unit 4. By configuring in this way, the surface of the raw water stored in the raw water storage unit 4 is not located above the bottom 707 of the purified water storage unit 7, and even if the raw water is purified by its own weight, Inflow into the purified water storage unit 7 is suppressed.

  In the portable water purifier of the present invention, it is also preferable to provide a water stop means in the flow path between the purification means 6 and the raw water storage unit 4. As the water stop means, for example, a check valve is preferable. This check valve is preferably one that does not open even when pressure is applied due to its own weight.

  Next, the effect | action of the portable water purifier of this invention is demonstrated. The raw water is poured from the opening 103 of the raw water storage container 1. After the water injection, the opening 103 of the raw water storage container 1 is closed with the first lid 2, the raw water storage unit 4 is sealed, and the second lid 3 is attached. By pressurizing the raw water storage unit 4 by the pressurizing means 5, the pressurized raw water flows into the purification means 6. Purifying means 6 removes organic substances such as chlorine, heavy metals, trihalomethane, bacteria, microorganisms, and other foreign matters. The purified water that has been purified flows into the purified water storage unit 7 and is stored.
