Preferably, described top panel is a upper porcelain slice, and lower panel is a lower porcelain slice.
Preferably, described water flowing canal mouth is arranged on the top panel.
Further, described pressure inlet is close to tank outer wall, and described movable contact is a spring plate, and the lower end of said spring plate is fixed on the water power divider wall of tank outer wall, and the other end is fixedly connected with the terminal elastic portion of pressure inlet through the insulation porcelain knob.
Further, the small-sized main body that described housing forms for the insulation exotic material, handle through chromium plating on the surface.
Preferably, described water tank and housing are integral type.
The technical conceive of the utility model is: when the rotation upper porcelain slice is communicated with feed water inlet, first water inlet, second water inlet with water flowing canal mouth; Beginning water filling in the water tank; The water that has hydraulic pressure simultaneously injects in the pressure inlet; The movable contact of pressure inlet end is extrapolated to stationary contact contacts, circuit is connected, and the water in the water tank begins heating; When rotating upper porcelain slice when the feed water inlet is sealed, when first water inlet, second water inlet were communicated with water flowing canal mouth, the aqueous reflux in the pressure inlet got in the water tank, and the supercharging inner pipe water pressure diminishes, movable contact and stationary contact disengaging, circuit disconnection; When rotating the sealing of upper porcelain slice to the second water inlet, feed water inlet, first water inlet are communicated with water flowing canal mouth, and the water that gets into from the feed water inlet directly gets into water inlet pipe without heating, thereby can use the water under the normal temperature.
The advantage of the utility model is: (1) rotating switch can cut off the power supply water heater, and is safe to use; (2) can realize the free adjustment of water temperature, current, can dry combustion method; (3) firing rate is fast, immediately hot-water supply; (4) switch contact-making surface resistance is little, and energy consumption is low.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
Referring to Fig. 1-7: a kind of quick electric water heater, comprise housing 1, water tank 2 is arranged in the housing 1, described water tank 2 be an integral type with housing 1, described water tank 2 is connected with water inlet pipe 3 and outlet pipe 4, and heating 5 is housed in the water tank 2; Described quick electric water heater also comprises pressure inlet 6 and hand switch 7; Described hand switch 7 comprises the top panel 9 and lower panel 8 of insulation; Described top panel 9 is a upper porcelain slice; Lower panel 8 is a lower porcelain slice, and upper and lower panel is close to rotationally, and lower panel 8 is provided with feed water inlet 10, first water inlet 11 that is connected with water inlet pipe 3, second water inlet 12 that is connected with pressure inlet 6; Top panel 9 is provided with water flowing canal mouth 13, and described water flowing canal mouth 13 has in twos the shape and size that cover or all cover described feed water inlet 10, first water inlet 11, second water inlet 12; Described heating 5 connects power supply through a hydraulic pressure switch, and described hydraulic pressure switch comprises the movable contact 14 and stationary contact 15 of cooperation, and described movable contact 14 is connected on the elastic portion 16 of pressure inlet 6 ends.
