  In recent years, in order to drink raw water such as tap water more deliciously, a pitcher type water purifier has been developed that contains a water purification cartridge in the pitcher, purifies the raw water and can be appropriately poured into a small container such as a cup, Various types of pitcher-type water purifiers have been proposed so far, and simple water purifiers similar to this pitcher-type water purifier are also known (see Patent Documents 1 to 4 below).

  For example, a pitcher-type water purifier disclosed in Patent Document 1 below includes a casing having a water inlet and a handle, and the casing is partitioned into upper and lower portions, that is, a raw water storage section and a purified water storage section. In addition, an opening is provided in a part of the partition wall, and a columnar water purification cartridge is mounted on the bottom of the raw water storage part communicating with the opening in a state where the cartridge is exchanged in a state of protruding into the water purification storage part. Yes. This water purification cartridge is provided with a mesh-like raw water inlet at the top and a mesh-like water outlet at the bottom, and the inside of the cartridge is filled with activated carbon and ion exchange resin as an adsorbent. .

In this pitcher type water purifier, the raw water supplied to the raw water reservoir in the upper part of the casing passes through the water purification cartridge with its own pressure, and the residual water contained in the raw water by the adsorbent of activated carbon or ion exchange resin when passing through the cartridge. Organic substances such as chlorine, salty odor, musty odor and trihalomethane, impurities such as heavy metals and aluminum are removed, and purified water is stored in the purified water storage section at the lower part. Water is being injected.

  Further, the pitcher-type water purifier disclosed in the following Patent Document 2 includes a container main body, an upper container provided with a communication portion that is detachably attached to the upper portion of the container main body and communicates with the lower portion of the container main body, and a communication portion. A water purification cartridge that can be detachably attached to the container, and a lid that removably closes the opening of the container body and the upper container. In this pitcher-type water purifier, raw water is purified by the same method as the pitcher-type water purifier in Patent Document 1, and the stored purified water is appropriately poured into a cup or the like.

  Furthermore, the following patent documents 3 and 4 introduce a simple water purifier similar to the pitcher water purifier. That is, these simple water purifiers include a container having an opening at the top, a lid for sealing the opening, and a purifier housed inside the container, and a check valve having a pressure relief mechanism on the lid. A pressurizing device is provided. In this water purifier, by operating the pressurizing device to increase the pressure in the container, the liquid is sent to the outside through the purifier, and at that time, the liquid is purified by the ion exchange resin and filtered through the porous membrane.

JP 2008-253992 A (paragraphs [0035] to [0040], FIG. 2) JP 2008-237981 (paragraphs [0016] to [0022], FIG. 2) Japanese Utility Model Publication No. 60-49987 (claim for utility model registration, Fig. 2) Japanese Utility Model Publication No. 60-49986 (Claim for Utility Model Registration, Fig. 3)

  The pitcher-type water purifiers of Patent Documents 1 and 2 are purified when the raw water supplied to the raw water storage unit (which is the upper container in Patent Document 2 and hereinafter the same) passes through the water purification cartridge with its own water pressure. And since it is stored in the lower purified water storage part (container main part), the user can pour the stored purified water into a glass etc. suitably and can drink it.

  Such a pitcher type water purifier is usually used to purify tap water or the like.

  However, in order to prevent bacterial contamination, tap water has a strong sterilizing power, is not harmful to the human body, and a chemical such as chlorine is added as a disinfectant having a high residual effect. Pitcher-type water purifiers are used to purify such tap water, and purified water is usually drunk in less time after purification, but depending on the user, the purified water can be cooled. In order to do this, it may be stored for a predetermined period, for example, 2-3 days or longer and then drunk.

  Purified water removes almost all bacteria and microorganisms during purification, but trace amounts of bacteria and microorganisms may still remain. These bacteria and microorganisms propagate, and in some cases, they can propagate to concentrations that affect the human body. For this reason, since these pitcher type water purifiers store purified water in the purified water storage part (container body), the stored purified water changes in quality over time, resulting in a decrease in water quality. Such a problem may occur. Further, since the raw water is passed through the water purification cartridge using its own pressure, it takes time to pass through the water purification cartridge, resulting in problems such as being inadequate for quick drinking and poor usability. In addition, these pitcher-type water purifiers are usually placed on a table or other table, and each time they are carried and used to pour water into a cup or the like. Raw water or purified water may flow out and contaminate the surrounding area. In addition, such a pitcher-type water purifier is not supposed to be cooled in a refrigerator or the like when it is laid down, so if it is laid down, the water inside will naturally flow out. become.

  The simple water purifiers of Patent Documents 3 and 4 above are carried to purify the water of lakes, swamps, ponds and rivers where bacteria etc. are breeding in the event of an emergency such as an earthquake or other disaster. It is carried to maintain the health of business travelers. Therefore, these simple water purifiers have troublesome water injection operations. That is, a pressure relief mechanism is attached to the pressurizing device, and the valve of this pressure relief mechanism is twisted to perform pressure relief to stop the liquid delivery. For this reason, there is a problem that the switching operability between the liquid delivery and the stoppage is poor and it is difficult to control the liquid outflow amount. In addition, when these simple water purifiers fall down, the raw water or purified water inside flows out and pollutes the surroundings, and it is not supposed to be used in such a way that it is cooled in a refrigerator etc. Therefore, the same problem as the problem of the above pitcher type water purifier is inherent.

  Therefore, the present invention has been made to solve such problems of the prior art, and the object of the present invention is to provide a pitcher that can purify and supply raw water for each water injection without storing purified water. The purpose is to provide a water purifier.
