Claims (7)

[Scope of utility model registration request] (1) By installing a removable dual-structure branch valve on an existing faucet, such as water supply, and communicating the branch valve to the water storage tank via a double hose with an inner hose inserted into the outer hose, A reserve is formed between the branch valve and the water storage tank to form a tank injection channel for storing water supplied from an existing faucet such as a tap into the water storage tank, and an external water supply channel for backflowing water when the water storage tank is full and supplying water to the outside. In a water storage and circulation system, a branch valve consists of a hanging pipe part and a horizontal pipe part that communicates with the hanging pipe part and protrudes from the middle part thereof, and works vertically inside the hanging pipe part and also connects the inside of the horizontal pipe part. A reserve water storage circulation device comprising an extending inner pipe. (2) The inner pipe of the branch valve is arranged eccentrically upward with respect to the horizontal pipe part so that the upper part of the inner circumferential surface overlaps, and the tip of the inner pipe protrudes from the horizontal pipe part in the extension direction, and the overlapping part 2. The reserve water storage and circulation device according to claim 1, wherein the outer circumferential surface of the inner tube is recessed to form a stepped wall. (3) The communication opening of the water storage tank consists of a water storage tank rim that projects upward, a water spout that is fitted into the water storage tank rim, and a cap that hooks the water spout onto the water storage tank rim. Utility model registration claim 1 is characterized in that it is composed of a circular plate-shaped base having a hole in the center, and a hollow cylindrical part that communicates with the hole and stands upward. Reserve water storage circulation device as described in Section 1. (4) Utility model registration claims 1 and 2, characterized in that the upper end of the hanging pipe part of the branch valve is provided with a connection means that can be attached and detached with one touch to an existing faucet such as water supply.
Reserve water storage circulation device as described in Section 1. (5) The existing faucet for water supply, etc. has a normal configuration with a collar, and the branch valve is attached to the existing faucet for water supply, etc. with the collar part removed from the existing faucet for water supply, etc. Claims for registration of a utility model characterized in that the lower end of the branch valve has the same threaded shape as the clasp connection structure of an existing faucet, such as a water tap, so that it can be connected to the lower end of the branch valve using an existing clasp hinge. The reserve water storage circulation device according to item 1. (6) The reserve water storage circulation device according to claim 1, wherein the water storage tank is covered with a protective cover with a styrofoam material interposed therebetween. (7) The reserve water storage and circulation device according to claim 1, wherein the water storage tank is made of a pressure-resistant structure.
