Hot water storage device capable of adjusting water storage capacity for intelligent home water supplying

The invention relates to the technical field of home water supplying equipment, and discloses a hot water storage device capable of adjusting the water storage capacity for intelligent home water supplying. The hot water storage device comprises an outer box; the interior of the outer box is fixedly connected with an inner box, and the bottom of the inner box is fixedly connected with an adjustingseat; and the interior of the adjusting seat is rotationally connected with a lead screw, the outer side wall of the lead screw is engaged with a first gear, and the top of the first gear is fixedlyconnected with a connecting rod. By arranging an anti-blocking pipe, a worm and worm wheel mechanism is arranged in the anti-blocking pipe, a spiral rod is arranged on a worm wheel, the lead screw drives a worm to rotate while driving an adjusting plate to adjust the water storage capacity, then the worm drives the worm wheel engaged with the worm to rotate, thus the worm wheel drives the spiral rod, while adjusting work is conducted, the rotating spiral rod stirs a water body around the anti-blocking pipe to make the water body form a water flow, thus the water flow stirs water scale to enable the deposited water scale to be cleared in time, and thus the trouble of the water scale blocking the water inlet end is avoided.
