Description

[Detailed explanation of the idea]

The water purifier of this invention can be reliably installed regardless of the type of water faucet or its diameter. Namely, the water purifier has a lid having a faucet fitting opening 2a on the top of a cylindrical plastic container 1. 3 is installed, a drainage hole 6 is provided on the bottom surface of the container 1, and a coconut shell activated carbon layer 8, a dechlorination stone layer 9, and a filter 11 are sequentially filled into the container 1 through water passage plates 12, and then the container 1 is closed. In a water purifier equipped with a rotary blade 7 which is rotated by a water flow above the container 1, a protruding flange 1a is formed on the upper part of the container 1, a groove 3a is formed on the lid 3,
Fit the protruding flange 1a and the groove 3a, and open the faucet fitting socket 2a.
A plurality of holes 2b', 2b'... are formed below the metal concentric cylinder 2b, and the lower part of the concentric cylinder 2b is simultaneously molded into the thickness of the short pipe 2b'. a concentric cylinder 2b protruding from the faucet fitting socket 2a,
It is characterized in that a male thread 2c is formed on the outer peripheral surface of the concentric cylinder 2b, and a female thread 2d is formed on the inner peripheral surface, and a thin silver film 16 is applied to the surface of each water passage plate 12. It should be noted that if the silver thin film 16 is applied to the water passage plate 12 via the nickel thin film 13, copper thin film 14, and nickel thin film 15 in order from the bottom layer, it will be easy to plate and will not easily peel off. Conventionally, a lid with a faucet attachment port is attached to the top of a cylindrical plastic container, a drainage hole is provided on the bottom of the container, and a layer of coconut shell activated carbon,
A water purifier was developed in 1987-31936 in which a layer of dechlorination stone and a filter were sequentially filled through a water passage plate, and rotary blades were installed above the container to be rotated by the water flow.
Although it is known and described in the publication, there is only one water faucet installation port and it is a fit-in type, so it can only be installed on one type of faucet, and can be used when the type and diameter of the faucet is different. It has the disadvantage that it cannot be used. In addition, conventional water purifiers have been developed in which a stepped cylindrical member consisting of a small diameter part and a large diameter part is attached to the faucet installation port via a protrusion, and a female thread is screwed into the large diameter part.
This method is known and described in Publication No. 20143, but it can only be installed on two types of faucets, and since it is installed by inserting plastic protrusions into the elastic faucet installation opening, it does not stick. The effect is small. This invention solves the above-mentioned disadvantages. Next, the structure of one embodiment will be explained in detail. A flange 1a is formed on the upper part of a cylindrical transparent plastic container 1, and a lid 3 made of elastic plastic is formed. is placed over the container 1, the concave groove 3a is fitted to the protrusion 1a, the elastic band ring 5 is fitted to the attachment part 4 to secure the lid 3, and the faucet fitting socket 2a is placed in the center of the upper surface of the lid 3. A concentric cylinder 2b made of chrome-plated brass is provided protruding from the thick wall part of the short pipe 2a' for forming the faucet insertion opening 2a, and a male screw 2c is attached to the outer peripheral surface of the concentric cylinder 2b.
A female thread 2d is formed on the inner circumferential surface. In addition, in order to protrude the concentric cylinder 2b to the short pipe 2a', the lid 3
Holes 2b', 2b', etc. shown in the first and third figures are opened below the concentric tube 2b, and the plastic communicates between these holes, and the concentric tube 2b
The lower edge of the tube is also wrapped in plastic to ensure that the concentric tube 2b protrudes and prevents water from spewing out from below and causing rattling during use. Further, above the container 1 and immediately below the faucet fitting 2a, a rotor blade 7 that is rotated by the water flow is provided, and below it there is a coconut shell activated carbon layer 8, a dechlorination stone layer 9, and a mineral natural stone layer 10. and filter 11 respectively through water holes 12', 12', 12'...
Each water passing plate 12 is made of plastic, and the chemical nickel thin film 13, copper thin film 14, and nickel thin film 15 are sequentially filled from the bottom layer to the surface as shown in the fifth figure. A thin silver film 16 is applied, and a drain port 6 is provided on the bottom surface of the container 1. Next, to explain how to use this example, container 1
When the faucet fitting socket 2a is inserted into the faucet 17, the water purifier is attached to the faucet 17 by the elasticity of the plastic material of the short pipe 2a'. In addition, a female screw 2d is screwed into the faucet 18 which has a male thread cut at the tip like a foam type faucet, and a male screw 2c is screwed into the faucet 19 which has a female thread cut at the tip. Attach to each faucet. Next, when the valve of the faucet is opened, water passes through the faucet and spout 2a, and the flow of tap water discharged from this faucet causes the rotor 7 to rotate, and the water flows into the container 1.
Each part passes through the inside evenly. In other words, the water is passed through the water passage plate 1
2. The water is discharged from the drainage hole 6 through the coconut shell activated carbon layer 8, water passage plate 12, dechlorination stone layer 9, water passage plate 12, mineral natural stone layer 10, water passage plate 12, and filter 11. In addition, when the water passes through the coconut shell activated carbon layer 8, it adsorbs the sterilizing bleach contained in the water and removes the odor peculiar to lime, and when it passes through the dechlorination stone layer 9, it absorbs the sterilizing bleach contained in the water. When passing through the mineral natural stone layer 10, natural mineral components are added to the water, and when passing through the filter 11, minute dust and rust are removed. It separates fine particles, weakens the force of water spouting, and prevents the water flowing out from the drain hole 6 from splashing back. Furthermore, each layer 8, 9, 10, 1
Since the water passing plates 12 are provided between the layers 8, 9, 10, and 11, the constituent materials of the layers 8, 9, 10, and 11 do not mix with each other. Since it is formed from sintered polystyrene material, the constituent materials of layers 8 to 10 will not spill out of the container 1. In addition to the above-mentioned water purification effect, since the passing water comes into contact with the silver thin film 16 applied to the surface of the water passage plate 12, it is disinfected and sterilized by the silver ions.
In addition, if you explain the water passage plate in detail, ABS
A water passage plate 12 is made of plastic material. As a first step, the surface of the water passage plate 12 is chemically roughened and a nickel thin film 13 is applied to a thickness of 0.05 microns. Next, as a second step, the copper thin film 14 is applied to a thickness of 6 to 8 microns by immersing it in a copper solution. Next, as a third step, a nickel thin film 15 is applied electrically to a thickness of 6 microns by immersing it in a nickel solution. Next, as a fourth step, the silver thin film 16 is applied to a thickness of 0.15 to 0.10 microns by immersing it in a silver solution. In addition, the results of the water quality test between the example with the silver thin film 16 and tap water, and the microbial test between the example with the silver thin film 16 and a water purifier with the same structure having a water passage plate without the silver thin film are as follows. It is as follows. [Water quality test results of tap water a that passed through the example with the silver thin film 16 applied and tap water b that did not pass through the example]

[Table] [Microbiological test results of Example a with silver thin film 16 and water purifier a' of the same structure with a water passage plate without silver thin film] Test method 1 A and a' were respectively placed at the water faucet. The one that was set up and used for about 15 to 20 minutes a day (180 water passes) for 7 days was used for this test. 2. General bacterial count and coliform bacteria test After a and a' were left in water for a certain period of time (1 hour, 4 hours, 1 day, 3 days), immediately after water flow, and after 10
About the passing water collected after passing water for seconds and 1 minute,
General bacterial count and coliform bacteria tests were conducted for each.

[Table] This design has a concentric tube protruding from the outside of the faucet fitting, and a male thread is formed on the outer circumferential surface of the concentric tube, and a female thread is formed on the inner circumferential surface of the concentric tube. It can be attached to three types of faucets: and faucets with female threads.Moreover, the faucet insertion opening is formed from a short tube, and multiple holes are provided below the concentric tube made of metal, and the bottom of the concentric tube is connected to the short tube. Because it is fixed by simultaneous molding within the wall thickness of the container, the effect of fixing the faucet fitting and the concentric tube is extremely large, and there is no risk of it coming off, and there is no wobbling, and the flange can be attached to the top of the container. , since it fits by forming a concave groove on the lid.
The bonding effect between the container and the lid is great, and since a thin silver film is applied to the surface of the water passage plate, the water flowing down inside the water purifier comes into contact with the silver film on the surface of the water passage plate, and is disinfected and sterilized by silver ions. It produces a remarkable water purification effect.
