Description

[Detailed description of the invention] This invention is an air pump that removes chlorine contained in water and is equipped with a water purifier that has effective sterilizing power, and also allows for easy water injection through its pumping action. This relates to a tabletop cold water bottle.

The general structure of a cold water cylinder used at home, especially in the summer, consists of a container with a water inlet and a lid member that opens and closes the spout.Tap water poured into the container is cooled by a refrigerator. That's how you get cold water. However, from a sanitary standpoint, tap water has residual chlorine at the supply end.
It is stipulated that chlorine should be maintained at 0.1 ppm or more, but in reality it is present in large amounts, and its chlorine odor often causes discomfort when drinking, especially in the summer. Therefore, a cold water cylinder has been proposed in which a water purifier filled with granular activated carbon for removing residual chlorine is installed inside the cold water cylinder container or on the lid of the conventional cold water cylinder. Cold water cylinders with such a structure had the following drawbacks.

In other words, since the particle size of the granular activated carbon used in conventional cold water cylinders of this kind is usually about 0.3 to 2 mm, the dechlorination reaction is slow, and therefore the normal flow rate flowing out from the spout of the cold water cylinder is low. There was a problem that dechlorination treatment could not be performed effectively on water of this type. Also, in order to solve this problem, it is possible to make the water purifier larger and ensure that the water runs for a longer time in the water purifier, but this is not possible with a small-sized water purifier that can be easily stored in a refrigerator and kept cold. There were still problems with the shape and structure of the cold water cylinder.

In addition, in cold water cylinders equipped with conventional water purifiers, the water purifier increases water flow resistance, making it difficult to pour out drinking water smoothly and lacking in quick water filling. The above-mentioned water purifiers did not have a bactericidal effect, so they had problems such as easy proliferation of bacteria.

The present invention was developed to eliminate the drawbacks of conventional water coolers, and its first purpose is to effectively remove chlorine from drinking water flowing through a water purifier, and also to improve the sterilization effect of the drinking water. To provide a cold water bottle equipped with a water purifier that can be used effectively. The second object is to provide a cold water bottle that can smoothly fill a desired amount of water without being affected by water flow resistance caused by a water purifier. The third purpose is to provide a cold water bottle that has a shape (miniaturization) that can be easily stored in a refrigerator installed in the home, making it possible to always have cold drinking water on hand and making it easy to carry. It is to be.

Embodiments of a cold water cylinder that can achieve the above object will be described in detail below with reference to the drawings.

In FIG. 1, 1 is a container body made of transparent glass, and on the front side of this container body 1 are
An axial recess 2 is formed in which a cup (not shown) can be placed, and an inner lid 5 is tightly screwed into the upper opening 3 of the container body 1 via a packing 4. It's becoming like that. A water injection pipe 6 formed in a substantially inverted L shape is attached to the inner lid 5, one end 6a of which is located at the inner bottom of the container body 1, and the other end is located outside the container body 1. It is formed in a water inlet 6b extending to the front. 7 is a through hole formed in the inner lid 5,
An air supply port 9 formed in the receiving tray 8 is fitted into the through hole 7 . Reference numeral 10 denotes an air tank made of a flexible rubber material, for example, and shaped like a bellows. Further, a coil spring 11 is installed inside the air tank 10 to restore the deflection of the air tank 10.
Further, a pressing member 12 is located at the top of the outside of the air tank 10. 13 is the pressing member 1
This outer cover 13 is fitted to the inner cover 5 and protects the flexible air tank 10 and regulates its position. Reference numeral 14 denotes an air valve that is attached to the saucer 8 and is capable of sucking air into the air tank, but prevents air from being pushed out to the outside. Reference numeral 15 denotes a water purifier that is removably fitted to the inner end 6a of the container main body of the water pipe 6, and this water purifier 15 has metal silver vapor-deposited on the surface of activated carbon fiber in the container 15a. It is stuffed with a desalinated material 15b made of at least one material. The activated carbon fibers used to create this desalinated material 15b are carbonized and activated synthetic fibers such as acrylic fibers, animal fibers such as wool, or vegetable fibers such as cotton. Value is 1.5g/g
Above, specific surface area 1000-1550m ² /g, average pore diameter
It has a performance of 14A° or more, which is superior to granular activated carbon. In particular, the outer surface area of activated carbon fiber is that of granular activated carbon.
It is 1.5 to 2.0 m ² /g, more than 100 times larger than 0.01 m ² /g, and therefore the reaction rate is extremely fast.

Regarding the thickness of the single fiber, if it is too thin, the mechanical strength will be weak, and if it is too thick, the reaction rate for removing residual chlorine will be slow, so the thickness of the single fiber should be in the range of 10 to 100 μm. It is desirable to do so.

Activated carbon fibers are an aggregate of activated carbon single fibers, but if the density of the single fibers is too small, the dechlorination effect will decrease, and conversely, if the density of the single fibers is too dense, the resistance when water passes through it will decrease. Because it gets bigger,
Preferably, it has a basis weight of 50 to 500 g ^per square meter.

Furthermore, since activated carbon fibers need to have a certain thickness when being subjected to dechlorination treatment, activated carbon fibers in the form of felt, which can be formed into any thickness, are most suitable for the purpose of the present invention.

Next, a method for depositing metallic silver on the surface of the activated carbon fiber will be described. For this deposition, a general method for depositing metal on the surface of a base material can be directly applied.

That is, the activated carbon fibers are placed above the vacuum container, and metallic silver placed in a crucible or the like is heated below the vacuum container to generate metallic silver vapor, which is applied to the surface of the activated carbon fibers. It is caused to precipitate.

When depositing metallic silver on the surface of activated carbon fibers, if the deposition is too thick, the water permeability will be impaired and the dechlorination effect will be reduced, and if it is too thin, the sterilizing ability and its sustainability will be reduced. The thickness is preferably in the range of 0.05 to 5 μm, more preferably in the range of 0.5 to 1 μm.

The structure of the cold water cylinder according to this embodiment has been described above, and its function will now be described.Tap water is poured into the container body 1 of this cold water cylinder and then cooled in a refrigerator to form cold water. Next, in order to pour out cold water from this cold water cylinder, press the pressing member 12 against the elasticity of the coil spring, and the cold water in the container body 1 will be pressurized by the air pressure in the air tank 10, and this cold water will be released from the water purifier 15. Water is injected from the spout 6b after passing through the salt material 15b. As this cold water passes through the desalination material, residual chlorine in the water is removed, and the treated water, in which bacteria in the water has been sterilized, is poured into the spout 6b. It is something that will be leaked more.

In the above embodiment, the water purifier 15 is detachably attached to the bottom side end 6a of the container body of the water injection pipe 6, but as shown in FIG. It may be interposed in the middle of the water pipe 6, or it may be detachably attached at the tip of the water injection pipe 6, that is, at the spout 6b, as shown in FIG.

As described above, the present invention has an air pump and a water injection pipe that pours out drinking water from a container by the operation of the air pump, and furthermore, a part of this water injection pipe is coated with metallic silver on the surface of activated carbon fiber. It is an air pump-type desk-top cold water cylinder that is detachably equipped with a water purifier filled with a desalinated material made by vapor deposition, and in particular, the water purifier 15.
uses a desalinating material made by vapor-depositing metallic silver on the surface of activated carbon fibers.Firstly, activated carbon fibers have an extremely fast reaction rate compared to granular activated carbon, so the capacity of the water purifier can be reduced. When processing cold water with a normal flow rate flowing through the spout pipe 6 of a cold water cylinder, the desired purpose can be sufficiently achieved even if the total volume of the desalination material is around 30 ^cm3 . Therefore, a small water purifier can have a sufficient dechlorination effect.

Furthermore, since the desalination material used in this invention has metallic silver vapor-deposited on its surface, it has sterilization ability, so it not only sterilizes when water is passed through it, but also cleans water inside and on the surface of the desalination material. It is possible to effectively prevent bacteria from multiplying inside the container, and even after the water flow is restarted, the treated water has a bacteria count that is far below the water quality standard of 100 bacteria/ml under the Water Supply Act. This allows stable and hygienic treated water to be obtained at all times. Furthermore, since the silver in the desalted material is in the form of metallic silver, the amount of silver leached into the treated water is small, and can be kept below the U.S. Public Health Service drinking standard of 0.05 mg/d.

In addition, as mentioned above, by making the water purifier more compact, it is also possible to make the overall structure and shape of the cold water bottle smaller, which makes it easy to store in a regular household refrigerator and to be portable. A cold water bottle with an advantageous shape can be provided. Furthermore, according to the present invention, the cold water in the cold water cylinder is made to flow through the water purifier using air pressure from the air pump, so the required amount of water can be achieved without being affected by the water flow resistance of the water purifier. The amount of water to be poured can be easily and smoothly obtained, and there is no need to tilt the cold water cylinder, so water can be poured easily.
