Described electric heating element 13 is integrated with metal water circulation road at water inlet electrothermal tube outsourcing aluminium alloy again; The water stream channel made by 13-1 heating wire, 13-2 magnesia powder, 13-3 metal tube, 13-4 aluminium alloy, 13-5 metal material, 13-6 weld, 13-7 binding post, 13-8 Inlet and outlet water interface are formed; And be formed as the out-of-date i.e. heating water of current stay vertical utensil 22; Described being integrated is integrated with the Combination of Methods of aluminium alloy by metal electric heat pipe and water stream channel welding or casting, is called the electric heating element 13 of aluminium bag electrothermal tube.

Described water tank 12, what be equipped with that water flows through formula and healed water outward stays vertical utensil 22; Electrothermal tube 13 controls electrothermal tube circuit conducting or closedown by water flow switch 20, determines different electrothermal tube work or do not work by driving switch 21; The water inlet of water flow switch 20 and the passage of water outlet are not directly communicate, but are separated by cover plate 2, and when there being water flow, water can promote cover plate 2, promote seal 3 and impeller 4 simultaneously, and movable contact 9 is contacted with stationary contact 8, circuit turn-on; Current are closed, and circuit disconnects.

The utility model beneficial effect and novelty directly control being turned on or off of electrothermal tube with current, and when having water flow, electrothermal tube is connected, and automatically disconnects when water is closed.

Detailed description of the invention

In accompanying drawing, the main body 1 of water flow switch, cover plate 2, seal 3, impeller 4, spring or spring leaf 5, cover plate 6, microswitch 7, stationary contact 8, movable contact 9, terminal 10, the pushing pin 11 of microswitch, water tank 12, electric heating element or electrothermal tube 13 are installed, water inlet pipe 14, outlet pipe 15, shell 17, water chew 18, water flow switch 20, driving switch 21, the out-of-date i.e. heating water of current stay vertical utensil 22, tank pressure control assembly 23, preheating switch 24, mechanical water resistance 25.

Fig. 1 to Fig. 5 is water flow switch 20, be made up of main body 1, cover plate 2, seal 3, impeller 4, spring or spring leaf 5, installation cover plate 6, microswitch 7, stationary contact 8, movable contact 9, terminal 10, what Fig. 1 Fig. 2 adopted is microswitch 7, Fig. 4 Fig. 5 be by contact and terminal directly on installation cover plate 6, the two function is identical with use, Fig. 1 Fig. 4 Fig. 5 is water route closed condition, and circuit disconnects; Fig. 2 be water in flow regime, the strength by water forces cover plate 2 to move, also simultaneously hydrodynamic reciprocating sealing part 3 and impeller 4, the pushing pin 11 promoted on microswitch, movable contact and stationary contact is combined, 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, and when discharging water, promote cover plate 2 moves, water flows from hole; On the body 1, inlet channel and water outlet water channel are not straight-through, and cover plate 2 must be made to move water could circulate mutually; Due to water channel close time, the feed water inlet of main body 1 is automatically closed by cover plate 2, and stationary contact and movable contact in Fig. 4 Fig. 5, only illustrate one group in figure, and actual product can make many groups.

Fig. 8 is the electric heater structural representation of the quick-heating type aluminium bag electrothermal tube heating of horizontal current switch control rule, water flow switch 20, driving switch 21, electrothermal tube 13 cooperating in figure, and driving switch 21, has rotary and button type structure, and the function of the two is identical; In figure, water flow switch 20 adopts microswitch 7, and according to the structure that Fig. 4 Fig. 5 makes movable contact be combined with stationary contact, function is identical; Many electrothermal tubes 13 are housed in water tank 12, and when discharging water, water flow switch 20 makes microswitch pushing pin 11, promotes movable contact 9 and contacts with stationary contact 8, now, determine that different electrothermal tubes is worked by driving switch 21; Guan Shui, circuit disconnects automatically.

Described water tank 12 metal or nonmetallic materials make, in-built preheating electrothermal tube, the water inlet pipe 14 be connected with water tank and outlet pipe 15, make of the non-metallic pipe of length >200mm, after Long-Time Service, even if electrothermal tube punctures, water-band electricity also can be guaranteed, permeate safety; When water tank 12 is used nonmetal, safer.

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