Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
Water heater includes instant heating type tap 100, electric heater and electric heating drinking machine etc., includes heating chamber 1 and heating
Activation system 2, heating chamber 1 is interior to be equipped with heating tube 11, and when water heater is in cold water shelves, heating start-up system 2 is not turned on；Work as heat
When hydrophone opens hot water shelves, heating start-up system 2 is opened.As depicted in figs. 1 and 2, for specific such as instant heating type tap 100,
Including total water inlet 101, total water outlet 102 and water tap 103.When needing using hot water, water tap 103 is adjusted to
The heating start-up system 2 of heating mode, instant heating type tap 100 is opened, and tap water enters from total water inlet 101, is heated and is opened
Dynamic system 2 flows out after heating through total water outlet 102.As shown in Fig. 2, water tap 103 connects in instant heating type faucet body 104
Switch interface 1031 on, total water outlet 102 connects on the outlet coupling 1021 of instant heating type faucet body 104.
As shown in Figures 3 to 5, heating start-up system 2 includes the hydraulic pressure chamber 21 with inlet opening 3 and apopore 4 and heating
Float switch in the movable contact spring 251 and static contact 252 and hydraulic pressure chamber 21 of pipe circuit connection.
Tap water enters to be entered in hydraulic pressure chamber 21 from inlet opening 3, and float switch applies movable contact spring 251 under the action of water flow
Add top power, movable contact spring 251 is allowed to conduct with static contact 252,11 heating starting of heating tube.Apopore 4 of the water flow from hydraulic pressure chamber 21
It enters and is disposed in the heating chamber 1 of heating tube 11.Specifically, water flow flow separately through the first inlet opening 3, the second inlet opening 5,
Heating chamber 1 is entered after second apopore 6 and the first apopore 4.When the heating shelves of water heater are opened, water flow is by entering
Then hydraulic pressure chamber 21 enters back into heating chamber 1, heated by heating tube 11 to water, while water flow can be in the bottom of piston 22
Into this can drive piston 22 to float.And when the cold water shelves of water heater are opened, water flow is directly over heating chamber 1 to tap
Water outlet, heating tube 11 not will start at this time.
The heating starting switch block of water heater, it is living including the piston 22 that can be floated in hydraulic pressure chamber 21 along water (flow) direction
Plug 22 includes main body 221 and the first shaft 222 set on main body one end, and the first shaft 222 is extended with the floating direction of piston 22,

Form the first space 201.
When flowing water passes through hydraulic pressure chamber 21, the first shaft 222 presses elastic contact blade 25, after the first gum cover 231 is extruded
In compressive state；When in hydraulic pressure chamber 21 without flowing water, piston 22 moves backward under the active force of the first gum cover 231, the first shaft
222 leave elastic contact blade 25.When water flow flows up, piston 22 is flowed up with water flow, and the first gum cover 231 is compressed；Work as water
When not flowing, the first gum cover 231 moves down piston 22 to down spring, at this point, movable contact spring 251 is separated with static contact 252, heating
The electrical circuit of pipe 11 disconnects.
As shown in Figure 3 and Figure 5, each active force of piston 22 is analyzed, the piston 22 in hydraulic pressure chamber 21 is by water flow
Active force, gum cover is to other active forces such as its elastic force；Comprehensively consider each active force, it, can be with when designing, producing the product
It is set in when being connected with water flow, the resultant force upward by one of piston 22 drives piston 22 to move up.And when non-water flow,
Piston 22 will receive the first gum cover 231 directed force F 1 downward to piston 22, comprehensive down force F1 and other vertical sides
Upward active force, the eventually active force downward by one of piston 22, this can enable piston 22 move down, to make
Contact 251 is separated with static contact 252.
