The other end of spring 33 is supported on mandrel 32 near that side of button 34.
Above-mentioned hot and cold water switching valve has two kinds of mode of operations, a kind of pattern be in summer or when do not need hot water,
Water can be allowed directly to flow to exhalant canal 13 by intake tunnel 11 by switching valve element 2, i.e., valve pole 21 be made by turning knob 22
90 degree are rotated, now Open Side Down for guiding gutter 211, intake tunnel 11 and exhalant canal 13 are turned on and recovery approach 12 is cut
Only, current reach switch valve core 3, and whether the at this moment water outlet of exhalant canal 12 can be controlled by switch valve core 3, and this is with known
Water tap it is the same.Another pattern is water conservation mode, when to winter or when need hot water, due to water plus
Hot device also has one section of square from the pipeline for simultaneously flowing through is also required to current preheating, therefore the above water outlet of a period of time from switching valve
Needs are reclaimed, and can now open switching valve element 2, and allowing current to flow to recovery approach 12 from intake tunnel 11 is carried out at recovery
Reason, specific operation is knob 22 is rotated counterclockwise 90 degree, and now guiding gutter 211 is open towards intake tunnel 11, now water
Stream flows to recovery approach 12 from intake tunnel 11, when the temperature of current reaches such as 45 degree of the temperature of setting, in recovery approach 12
Temperature sensing spring 42 receive thermal stretching, its elastic force more than spring 41 screen resilience, promote the displacement of mandrel 43 realize convex shoulder 431 and step
So as to turn off recovery approach 12, such hot water would not be wasted 121 closure, when needing to use water, will switch valve element 2
90 degree are rotated clockwise, current is flowed directly into exhalant canal 13 from intake tunnel 11, at this moment reclaimed energy road 12 and be switched valve element 2
Close, exhalant canal 13 can just be turned on or off hot water effluent by switch valve core 3.Specifically, when pressing switch valve
The button 34 of core 3（Near that side being connected with mandrel 32）When, mandrel 32 overcomes the screen resilience of back-moving spring 33 to do certain
Displacement, now the sealing ring 36 on bulge loop 321 leave the delivery port 311 of valve pocket 31, now exhalant canal 13 is opened, due to current
Screen resilience of the power on mandrel 32 more than back-moving spring 33 is applied to, mandrel 32 is maintained at opening, this is to continue hot water
The state of water outlet, when need not use water, presses the other end of button 34, and now mandrel 32 is subject to returning for back-moving spring 33
Elastic force, with the power that the button 34 in the same direction of screen resilience is applied to the shut-off on mandrel 32, the two external force are applied more than fluid
The opposite force on mandrel 32 is added in, the sealing ring 36 on bulge loop 321 engages shut-off exhalant canal 13 with delivery port 311 again, this
When due to mandrel 32 be subject to water flow pressure area relative to opening when its area it is smaller, not enough power overcomes back-moving spring 33
Screen resilience open exhalant canal 13, therefore exhalant canal 13 is maintained at closed mode.
Benefit of the invention has two, and one is that cold water is fully reclaimed, while hot water can avoid wasting；As long as two is when using
Hot-water mode is transferred to, when temperature reaches hot water temperature's automatic water stopping, people can go other things of doing completely, and without waiting for together
When also avoid hot water from wasting, reach abundant water-saving function.
