Embodiment two: this example is with embodiment one difference, for preventing flow backwards, sets up one-way valve in the water inlet of butterfly valve.
Embodiment three: this example is that with embodiment one difference consider the casting process at water tap, the water flow measurement impeller is difficult to be installed to the position of corner, adopts the feed-through locations that is set directly at the valve water inlet.
Above-mentioned governor circuit, water intake temperature sensing circuit and water outlet temperature sensing circuit temperature transmitting module, motor-drive circuit, valve driving mechanism etc. be integrated into a thick film module, in assembly process, be assemblied in the can at rear of water tap, install from bottom to top, seal with seal ring.The 7.2V lithium rechargeable battery is adopted in the power supply supply, and the replacing of battery also is to design on the limit of module, and battery design has waterproof ring, installs from the bottom up, and contact point of power source has self-locking mechanism, clicks battery locking, clicks battery and ejects.For by the temperature of cold and hot water inlet, the detection of flow, can obtain the temperature of mixing water: because no matter cold water or hot water, its specific heat is identical, and then the temperature of equal volume is that the water of X is the water mixing of Y with temperature, and the temperature of mixing water is (X+Y)/2.Around this principle, then can derive the water of water root Y temperature that flows through the X temperature of identical caliber with same flow velocity and mix the back temperature and be (X+Y)/2, if the flow velocity difference is A such as the flow velocity of the water of X temperature, the flow velocity of the water of Y temperature is B, and then the temperature of mixing water is exactly (AX+BY)/(A+B).
The pressure that the most normal problem of running into is exactly cold water or hot water in normal the use descends suddenly, the temperature variation that causes water outlet, influence is taken a shower even, because the utility model is provided with a current detection device, so when running into such situation, need not wait until that water outlet is checked through the folding degree that initiatively reduces the valve of another water supply line under the unusual situation of water temperature, reaches the stable purpose of holding temperature.Slowly increase the folding degree of the valve of pressure decline then simultaneously, safeguard the pressure of water outlet as far as possible.The control of cold water hot water flow is earlier open-minded among a small circle to the valve of cold water by governor circuit, the corresponding simultaneously valve of opening hot water among a small circle, and mixing water will slowly begin to increase until water velocity and the temperature of setting from small water flow.
After this product is replaced the water tap of traditional mechanical type manual temperature adjustment, the user can regulate the water temperature that needs in advance, starts governor circuit then, and water outlet water outlet this moment is the tap mouthful water outlet from the lower end, so that the user tests water temperature, do further temperature regulation.After temperature, flow data collector, processing, Control work, water temperature reaches the temperature that the user needs.This moment, the user can select by shower head water outlet (basket strainer) water outlet, or by the leading water outlet of the lower end bathtub that discharges water.In the shower process, the water temperature that induces the mouth of a river that microprocessor and sensor can be real-time drives butterfly valve by miniature motor, the flow of control hot and cold water, thus the water temperature that guarantees water outlet is constant on the temperature that the user sets.Finish in user's shower, can automatically water-out manners be set back by lower end water outlet water outlet, water temperature when simultaneously memory internal is closed can be automatically when use next time begins to regulate for the user by preceding water temperature when once closing, and avoids each use all will debug the loaded down with trivial details of temperature again.When the electricity shortage of governor circuit power supply, can give the user with the low voltage alarm, remind the user to change battery.Simultaneously, the user can oneself set high and low temperature control temperature limitation, guarantees that water temperature closes water valve under too high and low excessively situation, avoids causing scald or frostbite.Under the situation of governor circuit outage, do not influence the mode of traditional mechanical type manual temperature adjustment, do not influence the user and normally use shower set.If hotels etc. need long-term this product of use, can adopt ABAP Adapter to power for a long time, avoid often changing the trouble of battery.This design volume is little, is convenient to replace the tap of various showers, and price is low, can meet civilian cost requirement fully.
