Therefore, by Fig. 2 and cooperate Fig. 3,4,5 as can be known, altitude valve 3 of the present utility model remains on identical plane with the water level of hot water liner 42, and when seal ring 332 during with valve port 310 sealing of housing 31, the water route that housing 31 and hot water liner are 42 still is the state of intercommunication, so the water level in the hot water liner 42 can be subjected to the supervision of altitude valve 3, make the interior water level of water level and altitude valve 3 in the hot water liner 42 identical, therefore during the high water stage boundary in its water level reaches altitude valve 3, reserve tank 41 stops into water immediately to hot water liner 42.

When the user takes the boiling water that has heated from hot water liner 42 after, water level in hot water liner 42 and the altitude valve 3 will descend simultaneously gradually, when water level drops between the low-water level of cylindrical shell 32 and the high water stage, because upper float 333 continues to be subjected to the suction of magnetic 341, so still be positioned at the bottom (see figure 6) of lid 34, water level in hot water liner 42 and altitude valve 3 reduces again, when water level was low to moderate the low-water level that altitude valve 3 sets, following buoyancy aid 334 was adjusted stopping of piece 336 and can't be continued the (see figure 7) that descends again because of being subjected to low-water level; When water level is reduced to low-water level adjustment piece 336 belows, because the high water stage pressure of reserve tank 41 and the elastic restoring force of seal ring 332, and on, following

buoyancy aid

333 and 334 and the action of gravity of actuating rod 331, make the suction of 3331 of the sheet metals at magnetic 341 and upper float 333 tops can't be again greater than the sum total of aforementioned acting force, upper float 333 will break away from the magnetic force control of magnetic 341 and drop in the lower end of last accommodation space 321, make the actuating rod 331 homing (see figure 3)s that are subjected to upper float 333 pullings, make seal ring 332 open valve port 310, so, unboiled water can be supplemented in the hot water liner 42 by reserve tank 41, close port 310 again during high water stage in arriving hot water liner 42 and altitude valve 3, so, altitude valve 3 can move to guarantee the water yield in the hot water liner according to the state Automatic Cycle of the above.

By the explanation of above embodiment conjunction with figs. as can be known, the utlity model has following advantage and effect:

(1) switch power resources of the present utility model have saving electric power in buoyancy, magnetic force and gravity than solenoid valve, and save the trouble of manual operations such as push valve or knob valve, so the more existing really valve body of effect of the present utility model has progressive.
