Field of the Invention The present invention relates to a portable water purifier and, more particularly, to a water storage container, a pressurizing pump, and a filtration unit. It relates to a portable water purifier. 2. Description of the Related Art In recent years, in response to demands for "safer" and "more delicious" drinking water such as tap water, a water purifier provided with a filtration unit comprising a hollow fiber membrane and activated carbon has been developed. It has been developed and used in a wide range of fields, including drinking water, sterile water used in hospitals, and various industrial uses. [0003] The most popular type of water purifier at present is a faucet direct-connection type water purifier for tap water which is used daily at home. It is said that Effective uses of this water purifier include securing drinking water in camps and the like in Yamano, and securing drinking water in emergencies. Various simple or portable water purifiers have been proposed. Few are provided and are not very popular. [0004] The reason for this is that clean drinking water is relatively easily available in Yamano, Japan, and that well water can be used, but mainly the simple water purifiers provided so far have been used. In order to be portable, the water purifier body must be reduced in size, and since the water tank is provided in the water purifier, the amount of water stored is restricted, and water supply and purification are repeated frequently. It is due to need. In addition, the user needs to continuously pressurize while performing the water purification, and the working efficiency is extremely poor. [0005] In view of the above problems, the present invention can hold a large amount of raw water in a portable water purifier, and once pressurizing work is performed, the subsequent pressurizing is not required. It is an object of the present invention to provide a water purifier that can continuously purify water and has high water purification efficiency and work efficiency. A portable water purification set according to the present invention has a water inlet, a water inlet, an air inlet, and a water storage container having an expandable and contractible structure; A pressure pump for pressurizing the container, a pipe-shaped pipe detachably connected to the air inlet and the pressure pump, and communicating air from the pressure pump to the water storage container; A filtration unit for purifying raw water sent from the storage container, a pipe-shaped water distribution pipe detachably connected to the water supply port and the filtration unit, and feeds the raw water of the water storage container to the filtration unit, The water supply port or the filtration section is a water purifier having a water stopcock, wherein each component can be stored in a separated state. The portable water purifier set of the present invention has a structure in which each component is separable, so that the portable water purifier set can be stored compactly and can be easily carried. In addition, the water storage container has a structure that can expand and contract, and can store a large amount of raw water at the time of water storage. Therefore, once water is stored, frequent water supply work thereafter becomes unnecessary, and once storage is performed. By performing the pressure work, even when the water is stopped, the pressure inside the water storage container can be maintained by the water stopcock, so that it is not necessary to perform the re-pressurization at the time of reuse. Hereinafter, the present invention will be described in detail with reference to examples. [Embodiment 1] Fig. 1 is an explanatory view showing one embodiment of a portable water purifier set of the present invention, and Fig. 2 shows a state when the portable simple water purifier set in this embodiment is stored in a separated state. FIG. In the figure, 1 is a water storage container, 2 is a water inlet, 3 is a water inlet, 4 is an air inlet, 5 is a pressurizing pump, 6
Is a filtration unit, 7 is a water stopcock, 8 is a filtration unit discharge port, 9 is a pipe-shaped pipe 10, a pipe-shaped water pipe, 11 is a sterilizing agent (solution),
Numeral 12 indicates storage containers. The water storage container has a water inlet, a water inlet, and an air inlet. The water inlet is for supplying raw water.
It has a structure that can hold the inside of the water storage container in a sealed state under a pressure of about kg / m 2 . The water supply port is detachably connected to the pipe-shaped water pipe, and discharges raw water to the pipe-shaped water pipe. The air inlet is detachably connected to the pipe-shaped pipe, and flows air from the pressure pump into the water storage container. [0011] The shape of the water storage container is a bellows-like or other extendable container that can be folded when water is not stored, so that the storage space can be reduced when the device is carried. As the material of the water storage container, any material having a pressure resistance of about 0.5 kg / m 2 or more and a water resistance that does not cause harmful substances to seep into water can be used. In consideration of the discrimination of the amount and the requirement of being able to be stored in a folded shape, a plastic transparent sheet such as polyethylene or polypropylene is preferable. The size of the water storage container can be arbitrarily set as long as it can be stored in the storage container. However, if the water storage amount is increased, the amount of purified water in a single water injection and pressurization operation can be increased. . The pressurizing pump presses air into a water storage container filled with water and pressurizes the inside of the water storage container to push out water. Any type of pressurizing mechanism can be used. However, a lightweight and small space one is preferred. The pipe-shaped pipe is detachably connected to an air inlet of the water storage container and the pressurizing pump, and is a pipe for communicating air from the pressurizing pump into the water storing container. The piping has a pressure resistance of about 0.5 kg / m 2 or more. As a method for attaching and detaching the pipe-shaped pipe and the air inlet, a conventional method such as a fitting type or a one-touch joint type can be used as long as it has the above-mentioned pressure resistance. Also, as the material of the pipe-shaped pipe, any material such as a commonly used rubber hose and plastic hose can be used as long as it has the above-mentioned pressure resistance. By connecting the air inlet and the pressurizing pump using the pipe-shaped pipe, the workability of the pressurizing operation can be improved as compared with the case where the air inlet and the pressurizing pump are directly connected. As the filtration unit, a water purifier having a conventional structure comprising a combination of a generally used hollow fiber membrane and activated carbon can be used. The water inlet of the filter has a structure that is detachably connected to a pipe-shaped water pipe. The pipe-shaped water distribution pipe is detachably connected to a water supply port of the water storage container and the filtration part, and is a water distribution pipe for supplying raw water of the water storage container to the filtration part. The connection part and the water distribution pipe part Has a pressure resistance of about 0.5 kg / m 2 or more. As a method for attaching and detaching the pipe-shaped water distribution pipe and the water supply port, a conventional method such as a fitting type, a one-touch joint type or the like can be used as long as it has the above-mentioned pressure resistance. Also, as the material of the pipe-shaped water distribution pipe, any material such as a commonly used rubber hose or plastic hose can be used as long as it has the above-mentioned pressure resistance. By using the pipe-shaped water distribution pipe to connect the water supply port and the filtration unit, usability when discharging purified water can be improved as compared with a case where the water supply port and the filtration unit are directly connected. In the portable simple water purifier set of the present embodiment, a water stopcock is provided at the water inlet of the filtration unit. A water stopcock is used to suppress the discharge of water until the inside of the water storage container reaches a certain pressurized state when air is injected into the water storage container with a pressure pump. Any mechanism can be used as long as the mechanism stops the movement of water from the container to the filtration unit. The water stopcock only needs to be provided between the water supply port and the filtration unit. However, it is preferable to provide the water stopcock in the water supply port or the filtration unit rather than in the water distribution pipe. It is preferable in terms of ease. In addition, when the water stopcock is provided in the filtration unit, it is preferable to provide the water stopcock in the water entry unit in the filtration unit, since the water pressure is not applied to the filtration unit when water is stopped. When the portable water purifier set according to the present embodiment is used, water is purified by the following method. First, the air inlet of the water storage container and the pressure pump are connected by a pipe-shaped pipe, and the water supply port of the water storage container and the filtration unit are connected by a pipe-shaped water pipe. After injecting raw water into the water storage container from the water inlet of the water storage container, close the injection port. In this case, the amount of water to be injected is preferably ２ or less of the allowable amount of the water storage container 1. After injecting the raw water, air is injected from the pressurizing pump with the water stopcock provided in the filtration unit closed to pressurize the inside of the water storage container to about 0.2 to 0.3 kg / m 2. After that, open the stopcock. The water in the water storage container is continuously fed into the filtration unit, purified by the activated carbon and the hollow fiber membrane incorporated in the filtration unit, and flows out from the discharge port provided at the tip of the filtration unit. When the filtration is interrupted in the middle of use, the stopcock is closed, and when the filter is used again, the stopcock is opened, thereby enabling filtration without pressurizing again. In the portable simple water purification set of the present invention, since the water storage container, the pressurizing pump, the filtration unit, the pipe-shaped pipe, and the pipe-shaped water pipe are individually separable, they are separated as shown in FIG. In this state, it can be stored in a portable container. In the present embodiment, by being mixed in raw water, a sterilizing agent for sterilizing bacteria in raw water can be stored at the same time.
The disinfectant may be used by the user as needed, and is not essential. According to the portable water purifier set of the present invention, the individual components can be separated, so that the portable water purifier set can be compactly stored in a portable container, and the water storage container can be used. Since it can be increased, the filtration efficiency is increased.
Also, during use, continuous filtration is possible only by the initial pressurization operation, and the operation efficiency is excellent.
