[specific embodiment]

Extremely shown in Figure 5 like Fig. 1; A kind of water heater; Comprise heater fore shell 5, heater back cover 6, quartz heating tube 7, a pair of silica gel adapter sleeve 8 and water outlet threeway 9, a pair of silica gel adapter sleeve 8 is installed in the upper and lower end of quartz heating tube 7 respectively, and water outlet threeway 9 is installed in quartz heating tube 7 upper ends through silica gel adapter sleeve 8; The silica gel adapter sleeve 8 of quartz heating tube 7 lower ends is connected with into water threeway 1, is fixedly connected through screw rod 10 between said water inlet threeway 1 and the water outlet threeway 9; The upper and lower end of said water inlet threeway 1 is respectively equipped with delivery port 2 and water inlet 3; The middle part inner chamber of said water inlet threeway is equipped with the current Control Component 4 of water conduction between control delivery port 2 and the water inlet 3; Current Control Component 4 comprises magnetic float 40, water valve 41 and microswitch 42; Magnetic float 40 is installed in water valve 41 cavitys, and microswitch 42 corresponding magnetic floats 40 are installed in the outside of water valve 41; Kicker magnet A is housed in the magnetic float 40, and the kicker magnet B that is used to promote microswitch 42 contacts is repelled in being provided with kicker magnet A that water valve 41 outsides are corresponding each other; Offer the water valve mouth 410 with delivery port 2 conductings on the water valve 41, the magnetic float 40 control water valve mouths 410 in water valve 41 cavitys and the break-make of water inlet 3.Be provided with the LED Unit 55 of display power supply switch at heater fore shell 5 rear sides, offer sight vane 50 on the corresponding heater fore shell.

As depicted in figs. 1 and 2, said current Control Component 4 comprises also the water valve plain cushion 43 that is tightly connected with water valve 41 in water inlet threeway 1 inner chamber is set that water valve plain cushion 43 centers offer the through hole 430 that can be communicated with water inlet 3 and water valve mouth 410; The a pair of water valve sealing ring 44 that prevents that current leak in the into water threeway 1 of being used to also is installed on the outer wall of water valve 41; Also be respectively equipped with temperature control assembly 90 and pressure release assembly 91 in the said water outlet threeway 9, temperature control assembly 90 is made up of temperature control sealing ring a, thermal sensitive piece b and temperature controller c, and pressure release assembly 91 is made up of pressure release ball d, relief valve nut e and relief valve silica gel sheath f.

Like Fig. 1 to shown in Figure 5, after water gets into from the water inlet 3 of water inlet threeway 1, because water valve plain cushion 43 is pressed on into water threeway 1 inside by water valve 41; Water can only flow to water valve 41 inside from the through hole 430 at water valve plain cushion 43 centers, because magnetic float 40 is sealed the water valve mouth 410 of water valve 41, magnetic float 40 can be promoted by current by force; Water is flowed out from water valve mouth 410, and after magnetic float 40 was pushed, the kicker magnet A in the magnetic float 40 was promoted to move to right in the lump; Thereby move to right with the promotion of the repulsive interaction mutually kicker magnet B that kicker magnet B produces, this moment, kicker magnet B opened microswitch 42 because of repulsion effect meeting, and at this moment the indicator lamp of display water heater work is opened on the LED Unit 55 at heater fore shell 5 lower end sight vanes 50 places; Thereby accomplish whole current start-up course; Then, current are discharged from the delivery port 2 of water inlet threeway 1, get into quartz heating tube 7 heating in heater fore shell 5 and the heater back cover 6; The water outlet threeway 9 interior temperature control assemblies 90 that connect through quartz heating tube 7 upper ends are then controlled with pressure release assembly 91; Control needs the hot water of temperature outwards to supply with, and when the hydraulic pressure of quartz heating tube 7 is too high, carries out step-down through the pressure release assembly in the water outlet threeway 9 91; After closing water; The current motive force disappears, and kicker magnet B can return original position again because of the screen resilience of microswitch 42, at this moment switch closure; Promote the through hole 430 of the closed again water valve plain cushion 43 of magnetic float 40 simultaneously, the indicator lamp of display water heater work is closed on the LED Unit 55; Total can make the i.e. usefulness of water heater open, and Guan Shui promptly stops, and installs the effect that water flow switch control current can reach Switching Power Supply additional at the arbitrary end of water heater.

The above embodiment just is the preferred embodiment of the utility model, is not the practical range that limits the utility model with this, and the equivalence that all shapes according to the utility model, structure and principle are done changes, and all should be covered by in the protection domain of the utility model.
