Embodiment
The present invention is further described below in conjunction with drawings and Examples:
Consult Fig. 1, Fig. 3, this temperature-indicating water tap comprises water outlet housing 100, valve body 110 and operating stem 500, described water outlet housing 100 comprises feed-water end and waterexit end, described operating stem 500 connects described valve body 110 and is arranged on the outside of described water outlet housing 100, the feed-water end of described water outlet housing 100 is provided with cold water water inlet 120 and hot water water inlet 130, described cold water water inlet 120 and hot water water inlet 130 are by behind the described valve body 110, be communicated with an outlet pipe 140, the other end of described outlet pipe 140 is arranged on the waterexit end of described water outlet housing 100, described cold water water inlet 120 and hot water water inlet 130 parallel being set up in parallel, and be thermal conductor between two pipes, be provided with thermo-electric generation sheet 300 in the described thermal conductor, the huyashi-chuuka (cold chinese-style noodles) of described thermo-electric generation sheet 300 is over against described cold water water inlet 120, the hot side of described thermo-electric generation sheet 300 is over against described hot water water inlet 130, also be provided with luminous temperature indicating parts 4 on the described water outlet housing 100, described thermo-electric generation sheet 300 is electrically connected with described luminous temperature indicating parts 4.
The principle of thermo-electric generation sheet 300 is in the metal during non-uniform temperature, and the free electron of temperature eminence is larger than the free electron kinetic energy of temperature lower.As gas, when non-uniform temperature, can produce thermodiffusion, so free electron piles up in low-temperature end, thereby form electric field in conductor to temperature low side diffusion from temperature is high-end, just draw into a potential difference at the metal bar two ends.The diffusion of this free electron is performed until till the thermodiffusion balance of electric field force to the effect of electronics and electronics.When there was the temperature difference in thermo-electric generation sheet 300 two ends, the two ends of thermo-electric generation sheet 300 just produced voltage.
Consult Fig. 1, Fig. 2, above-mentioned temperature-indicating water tap, the cross section of described cold water water inlet 120 and hot water water inlet 130 is rectangle, and the pipeline of rectangle makes whole lean on nearer of distance between two pipes, and heat is transmitted more even, is conducive to the work of thermo-electric generation sheet 300.
Consult figure Fig. 1, Fig. 3, above-mentioned temperature-indicating water tap, described luminous temperature indicating parts comprise light source 410 and diffuser plate 420, described light source 410 is arranged on the edge of described diffuser plate 420, described diffuser plate 420 embeds in the described water outlet tube wall, described diffuser plate 420 is coated with liquid crystal ink coating 400 over against a side of described outlet pipe 140, and opposite side exposes described water outlet housing 100, and described thermo-electric generation sheet 300 is electrically connected with described light source 410.
Above-mentioned temperature-indicating water tap also is coated with protective coating 430 on the described liquid crystal ink coating 400, seals described liquid crystal ink 400, prevents volatilization.
Liquid crystal ink coating 400 refers to add the compound with crystal property in printing ink.Liquid crystal ink from production method, belongs to the microcapsule structure ink type; On using, belong to the temperature induced color changing printing ink category of thermal sensitivity.The quality mechanism of liquid crystal is exactly: utilize it that special wavelength light selective reflecting is formed.Liquid crystal ink has utilized this specific character of liquid crystal just, makes liquid crystal under the impact of weak current and temperature, and lattice changes and demonstrates LO-pattern and color.
Above-mentioned temperature-indicating water tap, described light source 410 is a monochromatic LED, described monochromatic LED is arranged on the limit of described diffuser plate 420.
Consult Fig. 4, in another embodiment, described light source 410 is the EL Cold light source, and described Cold light source is around described diffuser plate 420.
It is consistent that the EL Cold light source need to just can not reach surface brightness by light guide plate, scattering diluent, and brightness is even, soft, energy-efficient, luminance is high, low in energy consumption, than ordinary incandescent lamp economize on electricity 70%-80%; Do not produce heat, do not contain ultraviolet ray, electromagnetic-radiation-free, human body without injury, is the environmental type light source.
Above embodiment's working method is:
After above-mentioned temperature-indicating water tap is opened, produce the temperature difference between cold water water inlet 120 and the hot water water inlet 130, the two ends of thermo-electric generation sheet 300 just produce voltage light source 410 are lighted, enter outlet pipe 140 after hot water and the cold water mix, liquid crystal ink coatings 400 in the described outlet pipe 140 rear generation respective color of being heated, the light that diffuser plate 420 will produce diffuses on the liquid crystal ink coating 400, from the described diffuser plate 420 of described temperature-indicating water tap visual observation, namely can judge the temperature of water pipe 140 interior water, as long as hot water exists thermo-electric generation sheet 300 light source 410 must be lighted, therefore only need to observe the color of diffuser plate 420, namely can not occur the scald time
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
