Description
Technical field
The utility model relates to sensing sanitary appliance field, particularly relates to the sensing sanitary appliance of automatic turning off water during a kind of power circuit power-off.
Background technique
Sensing sanitary appliance be one can detect sensed user near and automatically can open impulse electromagnetic valve bath in use, use descendant to leave and can automatically close the auto-flushing sanitary equipment that impulse electromagnetic valve stops bath.Sensing sanitary appliance can prevent cross infection, and use health, convenience, a large amount of saving water resource, likes by masses deeply, uses very universal now.
But sensing sanitary appliance power line after opening impulse electromagnetic valve bath disconnects stops power supply, then sensing sanitary appliance just automatically can not be closed impulse electromagnetic valve and stop bath, and close watering until artificial and water could be stopped to flow out, this can cause the serious waste of water resources.
In order to solve this problem, the sensing sanitary appliance of Alternating Current Power Supply often configures jumbo electrochemical capacitor in the power supply adaptor of AC-DC conversion, when AC network power-off, the electric energy be stored in power supply adaptor in big capacity electrolyte capacitor can decline gradually, the circuit board of sensing sanitary appliance inside can detect that this changes, and send the instruction of closing impulse electromagnetic valve, utilize the dump energy in big capacity electrolyte capacitor to close impulse electromagnetic valve and stop bath, but problem when this can only solve AC network power-off, the sensing sanitary appliance of direct current supply is adopted on circuit main board, to increase booster circuit often, this circuit needs the IC that boosts, fast recovery diode, the electric capacity of farad level, after utilizing boosting, the electric energy be stored in farad capacitor makes impulse electromagnetic valve close and stops bath, can the object of automatic turning off water when although this reaches power circuit power-off, but the electronic parts and components adopted are many, cost is high, particularly farad capacitor, price is very expensive, and although farad capacitor capacity is large, but it is large that its shortcoming is internal resistance, large current discharging capability is poor, because impulse electromagnetic valve needs instantaneous large-current to drive, electric energy when this solution often there will be power circuit power-off in use in farad capacitor is because of can not heavy-current discharge and can not make the problem that impulse electromagnetic valve is reliably closed, have a strong impact on the reliability of product.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the sensing sanitary appliance of automatic turning off water during a kind of power circuit power-off.
The technical solution adopted in the utility model is:
The sensing sanitary appliance of automatic turning off water during a kind of power circuit power-off, comprise sensing sanitary appliance body and be located at the intrinsic circuit main board of sensing sanitary appliance, described circuit main board comprises power circuit, controller, voltage detecting circuit and drive circuit, power circuit comprises power supply and is parallel to an electrochemical capacitor of both ends of power, one output terminal of power circuit connects the input end of voltage detecting circuit, described voltage detecting circuit output terminal is connected with the input end of controller, the output terminal of controller connects drive circuit, and controller drives sensing sanitary appliance body to close water by drive circuit.
Described electrochemical capacitor is 2200 μ F.
Described controller is single-chip microcomputer.
The utility model adopts above technological scheme, and the circuit main board of sensing sanitary appliance adds the common small capacity aluminium electrolytic capacitor of a 2200uF, and the direct welded and installed of this capacitor, on circuit main board, is connected in parallel on both ends of power, for store electrical energy; When the power line power-off of power supply, circuit main board loses power supply, the electric energy now stored in 2200uF electrolytic condenser can be powered to circuit main board, its voltage can decline gradually, voltage detecting circuit on circuit main board can detect that this changes, and send this information to controller, controller can be analyzed this information, process, and send the control command of closedown, performed by drive circuit, utilize the electric energy stored in 2200uF electrolytic condenser to stop bath, reach the object of automatic turning off water during power circuit power-off.The 2200uF aluminium electrolytic capacitor volume that the utility model adopts is little, installs simple and convenient; Its internal resistance is little, and large current discharging capability is extremely strong, and the sensing sanitary appliance needing instantaneous large-current to drive can be made reliably to close; The utility model structure is simple, simple circuit, cost are extremely cheap, significantly increases the sensing sanitary appliance competitiveness of product in market.
