When the fan-shaped clamp 5311 of rotating shaft 531 bottoms is not all when bayonet socket 5831 below two swinging mountings, 58 right parts 583 matches, two swinging mountings 58 can both rotate, now press lower platen 565, pressing plate 565 drives depression bar 564 to match and make push rod 55 move down and locate with ratchet 562, the sealing-plug 551 of push rod 55 lower ends is just opened the centre bore of the second water proof ring 542, by the centre bore of the second water proof ring 542, water in the inner chamber of the first housing 51 below the first water proof ring 54 is the exhalant canal 512 from the first housing 51 through the centre bore of the second water proof ring 542 just, flow control valve 6 flows in water tank 1, the first water proof ring 54 hydraulic pressure above is just greater than the first water proof ring 54 hydraulic pressure below, hydraulic pressure just drives rapidly the first water proof ring 54 to move down, intake tunnel 511 and exhalant canal 512 on the first housing 51 are connected, water proof diaphragm 57 the second housing 52 inner chambers above are also intake owing to being communicated with the exhalant canal 512 of the first housing 51 simultaneously, hydraulic drives water proof diaphragm 57 is out of shape downwards, water proof diaphragm 57 just drives 571 and two fore-sets 572 of fore-set cover to move down, when two fore-sets 572 just drive respectively the end, lower-left 582 of two swinging mountings 58 that two swinging mountings 58 are rotated counterclockwise, the contact 591 of two microswitches 59 is just withstood respectively in the right part 583 of two swinging mountings 58, two microswitches 59 are just connected the power supply of two electric heating tubes 2 simultaneously, two electric heating tubes 2 just heat to the water entering in water tank 1, outlet pipe 4 just can be exported hot water.
When using hot water, click again pressing plate 565, pressing plate 565 drives depression bar 564 to match with ratchet 562, under stage clip 563 effects, depression bar 564 and push rod 55 all move up and locate, depression bar 564 band dynamic pressure plate 565, two T shape bars 566 move up and locate, when two T shape bars 566 just pull respectively the end, upper left 581 of two swinging mountings 58 that two swinging mountings 58 are clockwise rotated, 591, two of the contacts microswitch 59 that the right part 583 of two swinging mountings 58 just departs from respectively two microswitches 59 just cuts off the power supply of two electric heating tubes 2 simultaneously; Now the sealing-plug 551 of push rod 55 lower ends is blocked the centre bore of the second water proof ring 542, the water of the intake tunnel 511 on the first housing 51 just progressively the moisturizing hole 541 from the first water proof ring 54 end faces to the inner chamber water-filling of the first housing 51 below the first water proof ring 54, in water filling process, the first water proof ring 54 also progressively moves up, after moving into place, the first water proof ring 54 just cut off again intake tunnel 511 and exhalant canal 512 on the first housing 51, therefore play the function that postpones to close water, can take away two waste heats on electric heating tube 2, prevent from scalding people.
When the fan-shaped clamp 5311 of rotating shaft 531 bottoms is when bayonet socket 5831 below one of them swinging mounting 58 right part 583 matches, swinging mounting 58 by card column just can not rotate, the microswitch 59 of corresponding swinging mounting 2 is failure to actuate, the electric heating tube 2 of being controlled by microswitch 59 just can not be switched on, and therefore by rotating shaft 531, can carry out the selection of heating power.
Below be only preferred embodiment of the present invention, the change that those skilled in the art does to be equal to by claim all falls into the protection domain of this case.
