Under original state, outlet pipe 4 not water outlet, two electric heating tube 2 no powers, the the first water proof ring 54 be contained in the first housing 51 is in upper, the intake tunnel 511 on the first housing 51 and exhalant canal 512 are cut off, water is full of the inner chamber of the first housing 51 be in below the first water proof ring 54 by the moisturizing hole 541 on the first water proof ring 54 end face, push rod 55 is also in upper simultaneously, and the centre bore of the second water proof ring 542 blocked by the sealing-plug 551 of push rod 55 lower end.
When the fan-shaped clamp 5311 of rotating shaft 531 bottom does not all match with the bayonet socket 5831 below two swinging mounting 58 right parts 583, two swinging mountings 58 can both rotate, now press lower platen 565, pressing plate 565 drives depression bar 564 to match with ratchet 562 to make push rod 55 move down and locate, the centre bore of the second water proof ring 542 just opened by the sealing-plug 551 of push rod 55 lower end, by the centre bore of the second water proof ring 542, be in water in the inner chamber of the first housing 51 below the first water proof ring 54 just through the centre bore of the second water proof ring 542 from the exhalant canal 512 the first housing 51, flow control valve 6 flows in water tank 1, hydraulic pressure above first water proof ring 54 is just greater than the hydraulic pressure below the first water proof ring 54, hydraulic pressure just drives rapidly the first water proof ring 54 to move down, intake tunnel 511 on first housing 51 is connected with exhalant canal 512, the second housing 52 inner chamber simultaneously above water proof diaphragm 57 is also intake due to the exhalant canal 512 being communicated with the first housing 51, hydraulic drives water proof diaphragm 57 is out of shape downwards, water proof diaphragm 57 just drives fore-set cover 571 and two fore-sets 572 to move down, when two fore-sets 572 just drive the lower left end portion 582 of two swinging mountings 58 that two swinging mountings 58 are rotated counterclockwise respectively, the right part 583 of two swinging mountings 58 just withstands the contact 591 of two microswitches 59 respectively, the power supply of two electric heating tubes 2 just connected by two microswitches 59 simultaneously, two electric heating tubes 2 just heat to the water entered in water tank 1, outlet pipe 4 just can export hot water.
During without the need to using hot water, click pressing plate 565 again, pressing plate 565 drives depression bar 564 to match with ratchet 562, under stage clip 563 acts on, depression bar 564 and push rod 55 all move up and locate, depression bar 564 is with dynamic pressure plate 565, two T-shaped bars 566 move up and locate, when two T-shaped bars 566 just pull the end, upper left 581 of two swinging mountings 58 that two swinging mountings 58 are rotated clockwise respectively, the right part 583 of two swinging mountings 58 just cuts off the power supply of two electric heating tubes 2 simultaneously with regard to 591, two, the contact microswitch 59 departing from two microswitches 59 respectively; Now the centre bore of the second water proof ring 542 blocked by the sealing-plug 551 of push rod 55 lower end, the water of the intake tunnel 511 on the first housing 51 is just progressively from the moisturizing hole 541 the first water proof ring 54 end face to the inner chamber water-filling of the first housing 51 be in below the first water proof ring 54, in water filling process, first water proof ring 54 also progressively moves up, when the intake tunnel 511 just cut off again after the first water proof ring 54 moves into place on the first housing 51 and exhalant canal 512, therefore the function postponing to close water is played, the waste heat on two electric heating tubes 2 can be taken away, prevent from scalding people.
When the fan-shaped clamp 5311 of rotating shaft 531 bottom matches with the bayonet socket 5831 below one of them swinging mounting 58 right part 583, just can not be rotated by the swinging mounting 58 of card column, the microswitch 59 of corresponding swinging mounting 2 is failure to actuate, the electric heating tube 2 controlled by microswitch 59 just can not be energized, and therefore can be carried out the selection of heating power by rotating shaft 531.
Below be only the present invention's preferred embodiment, those skilled in the art makes by claim the protection domain that equivalent change all falls into this case.
