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, cover plate 6 is installed, microswitch 7, stationary contact 8, movable contact 9, terminal 10, the pushing pin 11 of microswitch, water tank 12, electrothermal tube 13, water inlet pipe 14, outlet pipe 15, heat-insulation layer 16, shell 17, non-pressure outlet open-type water nozzle 18, preheating switch 19, water flow switch 20, driving switch 21, mechanical water resistance 22, tank pressure control parts 23, current out-of-date i.e. add hot water in vertical utensil 24, water 25.

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 is the quick-heating type electric water heater structural representation of the Hybrid Heating 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, and external current out-of-date i.e. add hot water in vertical utensil 24, the water inlet pipe 14 being connected with water tank and outlet pipe 15, by length > non-metallic pipe of 200mm makes, after life-time service, make water charged even if electrothermal tube punctures, also ensure that out water security；When water tank 12 is used nonmetal, safer.

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