Mixed water delivery port 217 is offered on the wall of side, being provided between the dynamic potsherd 262 and Dingtao ceramics 263 can corresponding water outlet knot
(water flowing out structure can be not discussed herein structure using potsherd and the conventional water flowing out structure of Dingtao ceramics is moved in existing valve element
Concrete structure, not shown in figure), offer mixed water water inlet 218 on the side wall of the correspondence water flowing out structure of the valve core shell 21.
The macromolecular material injection moulding separated out without halogen atom or use ring that the structure of above-mentioned valve element 2 can be modified using glass
The casting of guarantor's type copper alloy is machining.
The faucet body 1, as shown in figure 1, being formed with spool chamber 11 in it and being respectively communicated with the hot-water cavity of spool chamber 11
12nd, cold water cavity 13 and water chamber 14, offer on the faucet body 1 and lead to the hot water water inlet connecting hole 121 of hot-water cavity 12, lead to
To the cold water water inlet connecting hole 131 of cold water cavity 13, lead to the apopore (not shown) of water chamber 14 and lead to spool chamber 11
Valve element mounting hole 111, the valve element 2 separates each cavity seal, as shown in FIG., the hot water water inlet of the valve element 2
213 correspondence hot-water cavities 12, the correspondence cold water cavity 13 of cold water water inlet 214, the correspondence water chamber 14 of water side 212；The valve element 2 will also
The sealed separation of spool chamber 11 goes out to switch water flowing out structure chamber 15, and the mixed water delivery port 217 and mixed water water inlet 218 correspondence are in switch
In water flowing out structure chamber 15, water chamber 14 is led in the connection of the water side 212, the configuration said structure of faucet body 1 of the structure
Valve element 2, the separate space wall between each chamber in inside of faucet body 1 is regular smooth, and water channel is short, spacious unobstructed, is conducive to being cast as
Type.
It is respectively equipped with down in spiral shell and spiral shell on the hot water water inlet connecting hole 121 and cold water water inlet connecting hole 131 and is provided with only
Inverse valve 3, prevents because there is string water when hot and cold water pressure value is inconsistent.
The water intake end of the check (non-return) valve 3 is provided with screen pack 4.
The hot water water inlet connecting hole 121 is set by the end of faucet body 1, and the spool chamber 11 is connected with hot water water inlet
Hole 121 is set with end, and chamber next door between the hot-water cavity 12 and cold water cavity 13 intakes connecting hole 121 and heat near hot water
Water inlet 213 and do not influence the structure of other parts to set, from Fig. 1 it can be seen that, the structure setting hot-water cavity 12 is empty
Between take whole faucet body 1 for small part, the space of cold water cavity 13 is big, hot-water cavity 12 when so capable of reducing using
Heat conduction scope, there is the protective action for preventing the large area of faucet body 1 hot.
The use process of above-mentioned constant-temperature shower faucet is such：First, temperature control handwheel 281 is rotated, makes instruction thereon
Temperature position required on the temperature scale scale of temperature scale ring 282 is pointed in position, and regulation is driven when rotating temperature control handwheel 281
Revolving part 252 is rotated, and due to there is limiting structure 256 to limit between adjustment slide 253 and joint 27, it is rotated and regulation is slided
Threads between part 253 and regulation revolving part 252, therefore adjustment slide 253 can realize axle during the regulation rotation of revolving part 252
To sliding compression back-moving spring 24, the length needed for making the length of back-moving spring 24 reach set water temperature, while adjust sliding
Moving part 253 presses to back-moving spring 24；Then, rotating water handwheel 5 drives valve core rod 261 to rotate dynamic 261 turns of the potsherd of drive
It is dynamic, make the opening state that the water flowing out structure between potsherd 262 and Dingtao ceramics 263 is different water yields, in hot-water cavity 12
Water enter in valve core shell 21 from hot water water inlet 213, water in cold water cavity 13 enters valve core shell 21 from cold water water inlet 214
It is interior, cold water and hot water mixing water outlet, if mixed water temperature reaches the temperature for extending the temperature-sensitive of shape memory alloy spring 23, now
Shape memory alloy spring 23 experiences mixing water temperature and produces phase transformation elongation, and elasticity tension promotion sliding shoe 22 makes cold water water inlet
214 become big, and hot water water inlet 213 diminishes；Conversely, shape memory alloy spring 23 does not extend, in the elasticity of back-moving spring 24
Under tension force, sliding shoe 22 makes cold water water inlet 214 diminish by promotion, and hot water water inlet 213 becomes big, by marmem bullet
The interaction force produced at a temperature of mixing water of spring 23 and back-moving spring 24 balances two length of spring, that is, determine cold
Water inlet 214 and the size of hot water inlet 213, determine cold and hot water-carrying capacity mixing match, and institute is flowed into switch water flowing out structure chamber 15
The mixing water of design temperature and keep the constant of water temperature.
The two ends of the sliding stroke of sliding shoe 22 are respectively closing hot water inlet 213 and cold water inlet 214.
Valve element of the invention 2 is provided with high temperature adjustment structure, by the structure water temperature scalded will likely be caused to be divided into
High temperature, when high-temperature water outlet is needed, it is necessary to further adjust the structure, so as to realize the function of safety temperature adjusting, for preventing nothing
Meaning high-temperature water outlet causes to scald.The implementation process of the function is：Alignment pin 285, i.e. fixture block 2872 are blocked by fixture block 2872
It is safe stop block, the elasticity tension for having spring 286 is limited, and alignment pin 285 arbitrarily will not be avoided turning over fixture block 2872, is needing
When adjusting higher temperature, press button 284 and drive alignment pin 285 to slide into the other end of guide groove 2812, avoid fixture block
2872 defined position, then rotates temperature control handwheel 281 and can be turned to high temperature range (maximum temperature is complete hot water temperature).
Due to being provided with segmental arc 2871, segmental arc 2871 has thickness, and avoiding fixture block 2872 in alignment pin 285 enters segmental arc 2871
Afterwards, the medial surface of segmental arc 2871 is stuck in, during regulation high-temperature water outlet, button 284 need to be constantly in pressed status, when in use people
Can argue current constant temperature temperature out by confirming that this pressing operation and temperature scale are pointed to.
Structure of the invention is similarly applied to Kitchen tap, tap for washbasin etc..
Above-described embodiment and schema and non-limiting product form of the invention and style, any art it is common
Appropriate change or modification that technical staff is done to it, all should be regarded as not departing from patent category of the invention.
