Described water tank 12 is molded by metal material or nonmetallic materials or blowing makes；

Electrothermal tube (13) is that ceramic heating assembly has two kinds of structures, a kind of is made by positive temperature coefficient PTC thermo-sensitive material, and the both sides of ceramic heating assembly are attached to aluminum metal tube cavity or the outside of internal water flowing, after energising, tow sides can produce heat, by conduction of heat, the water flow through in adding heat pipe；Another kind is that heating wire pottery is fully wrapped around, and makes circle or flat through high temperature sintering, is arranged in water tank, the water that heating is flow through；

Described mechanical water resistance 22 refers to water inlet pipe 14, outlet pipe 15, by length > non-metallic pipe of 200mm makes；

Described tank pressure controlling organization 23, is made up of main body 23-1, the valve 23-2 being contained in main body, and sealing member 23-3 and spring 23-4, is contained in inlet channel or water flow switch；During water inlet, spring is opened by pipe-line system pressure, water inlet, and when outlet misloading or dead by resistance, within water tank 12, pressure can progressively increase to 0.2mpa, water inlet can be automatically switched off under valve 23-2 effect, it is ensured that safety.

Described instantaneous water heater refers to that water tank capacity is the least, water flows through the most heated electric heater, feature is: controlled electrothermal tube circuit on and off equipped with many electrothermal tubes 13 by water flow switch 20 in water tank, driving switch 21 determine different electrothermal tube work or do not work；The water inlet of water flow switch 20 and the passage of water outlet are not directly to communicate, but are separated by cover plate 2, and when there being water to flow, water can promote cover plate 2, simultaneously promotion sealing member 3 and impeller 4, and makes movable contact 9 contact with stationary contact 8, circuit turn-on；Current are closed, and circuit disconnects.

Beneficial effect of the present invention and novelty are directly to control being turned on or off of electrothermal tube with current, and when having water to flow, electrothermal tube is connected, and water disconnects when closing automatically.

Detailed description of the invention

In accompanying drawing, the main body 1 of water flow switch, cover plate 2, sealing member 3, impeller 4, spring or spring leaf 5, install cover plate 6, microswitch 7, stationary contact 8, movable contact 9, terminal 10, the pushing pin 11 of microswitch, water tank 12, ceramic heating assembly 13, water inlet pipe 14, outlet pipe 15, shell 17, water nozzle 18, mechanical water resistance 19, water flow switch 20, driving switch 21, current out-of-date i.e. add hot water control parts 23, preheating switch 24 in vertical utensil 22, tank pressure.

Fig. 1 to Fig. 5 is water flow switch 20, it is made up of main body 1, cover plate 2, sealing member 3, impeller 4, spring or spring leaf 5, installation cover plate 6, microswitch 7, stationary contact 8, movable contact 9, terminal 10, Fig. 1 Fig. 2 uses microswitch 7, Fig. 4 Fig. 5 is directly to make contact and terminal installing on cover plate 6, the two function is identical with use, Fig. 1 Fig. 4 Fig. 5 is water route closed mode, and circuit disconnects；Fig. 2 is that water forces cover plate 2 to move in flow regime, the strength by water, moves sealing member 3 and impeller 4 the most simultaneously, promotes the pushing pin 11 in microswitch, makes movable contact and stationary contact combine, circuit turn-on；If closedown water route, then circuit disconnects；The shape of Fig. 4 cover plate 2 is different, and cover plate 2 has multiple hole, when discharging water, promotes and moves on cover plate 2, and water flows from hole；On the body 1, inlet channel and water outlet water channel are not straight-through, it is necessary to making cover plate 2 move water could circulate mutually；When closing due to water channel, the feed water inlet of main body 1 is closed by cover plate 2 automatically, and stationary contact and movable contact in Fig. 4 Fig. 5 only illustrate one group in figure, actual product can make many groups.

Fig. 8 Fig. 9 is the quick-heating type ceramic heating assembly electric heater structural representation of vertical type water flow on-off control, and in figure, water flow switch 20, driving switch 21, electrothermal tube 13 cooperating, driving switch 21, have rotary and button type structure, and the function of the two is identical；In figure, water flow switch 20 uses microswitch 7, makes, according to Fig. 4 Fig. 5, the structure that movable contact is combined with stationary contact, and function is identical；Equipped with many electrothermal tubes 13 in water tank 12, when discharging water, water flow switch 20 makes microswitch pushing pin 11, promotes movable contact 9 to contact with stationary contact 8, now, driving switch 21 determines that different electrothermal tubes is worked；Guan Shui, circuit disconnects automatically.

Described water tank 12 is molded by metal or nonmetallic materials or blowing makes, on water tank outer be equipped with current out-of-date i.e. heat in vertical utensil 20.

Product in accompanying drawing, water temperature shows can use digital-scroll technique or fuzzy display, and in figure, arrow is water (flow) direction.
