The purpose of this utility model is to provide a kind of dual sense water tap, be provided with indirect induction window and sensor and directly respond to window and sensor, employing is stretched to the indirect induction firing control that indirect induction window leaves immediately with hand both can realize responding to indirectly control mode and the directly conversion between the induction control mode by control circuit, can open or close water outlet automatically with this induction firing control control water tap again, can also under direct induction state of a control, directly hand be stretched to or leave faucet outlet, whether exist and control water tap and open or close water outlet automatically by the sensor hand in the direct induction window, use more convenient, water-saving result is better, and application area is more extensive.

The technical solution of the utility model is: a kind of dual sense water tap, comprise induction window and inner sensor thereof, control circuit and solenoid valve, it is characterized in that: on water tap, be provided with indirect induction window and sensor and directly respond to window and sensor, its indirect induction window and sensor are located on the water tap outside the direct inductive sensor surveyed area, it be detect hand with it near and leave the difference of used time immediately and produce different pulse signals and discern and realize directly responding to control mode by control circuit with the conversion between the induction control mode indirectly and control water tap and open or close water outlet automatically.Directly whether induction window and sensor are located at and are convenient to detect hand near the faucet outlet and exist, if exist just by control circuit and the automatic water outlet of electromagnetic valve water tap, otherwise just cut off the water automatically.

The utility model compared with prior art has the following advantages: both can use and hand is stretched to the indirect induction firing control control water tap that indirect induction window leaves immediately open or close effluent functions automatically by user's needs, can realize directly responding to control mode and the conversion between the induction control mode indirectly again, can also use the direct induction of stretching out one's hand water to let go to cut off the water of being convenient to wash one's hands and simply getting article express developed to open or close effluent functions automatically, be not only applicable to the public place, and be applicable to the toilet and the kitchen of residential building, use more convenient, water-saving result is better, and application area is more extensive.

The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing 1 is a schematic representation of the present utility model;

Accompanying drawing 2 is skeleton diagrams of the present utility model;

Referring to accompanying drawing 1 and accompanying drawing 2, at water outlet place direct induction window 1 and sensor 4 are set near water tap 3, whether its detecting area is convenient to detect hand and is existed in the scope that people wash one's hands.The side of the water tap 3 outside the detecting area of directly induction window 1 and sensor 4 or above (side of only drawing among the figure) indirect induction window 2 and sensor 5 are set, its detecting area is not overlapping with the detecting area of direct induction window 1 and sensor 4, and detectyion range is less than direct inductive sensor 4.

Referring to accompanying drawing 2, control circuit 6 comprises singlechip chip 7, drive circuit 8.Directly inductive sensor 4, indirectly inductive sensor 5, solenoid valve 10, power supply 11, be connected with singlechip chip 7, drive circuit 8 on the control circuit 6 by lead and printed circuit board (PCB).

For both can having been realized, indirect induction mode responds to control mode and the directly conversion between the induction control mode indirectly, induction control water tap opening and closing indirectly, we utilize hand to stretch to the difference that indirect induction window 2 leaves needed time immediately and give single-chip microcomputer 7 by the different signal (pulse width or pulse number) of indirect inductive sensor 5 outputs, by single-chip microcomputer 7 identifications and realize conversion and control.

Single-chip microcomputer 7 writes our needed control program and is welded on the circuit board.Directly inductive sensor 4 and indirectly inductive sensor 5 also can adopt pyroelectric infrared sensor by fired infra-red component and infrared receiver component or form.Power supply 11 adopts voltage adapter or the battery that the 220V exchange conversion is become low-voltage direct.If use battery as power supply, single-chip microcomputer 7 must be selected the low power consumption model, and solenoid valve 10 must adopt pulse-controlled electromagnetic valve.

During use, directly responding to the direct induction window 1 that under the state of a control hand is directly stretched to the faucet outlet place, photostat 4 detections are in one's hands just sends corresponding signal to the single-chip microcomputer 7 in the control circuit 6, single-chip microcomputer 7 sends corresponding instruction and gives drive circuit 8, open solenoid valve 10 automatic water outlets by drive circuit 8 again, hand is regained just cut off the water automatically.Hand is stretched to indirect induction window 2 regain immediately, automatic water outlet when just entering indirect induction state of a control is automatically stretched to hand indirect induction window 2 again and is regained immediately and then cut off the water automatically.In indirect induction state of a control hand is stretched to (this sensitive time should be obviously greater than the time of the normal open and close of the induction indirectly water tap) withdrawal immediately that makes a short pause a little of indirect induction window 2, then enter direct induction state of a control automatically.
