A kind of automatic flushing toilet

Technical field

The utility model relates to a kind of toilet, particularly be a kind of automatic flushing toilet.

Background technology

The toilet of selling on the market much has the auto-flushing function, but tap water can often cut off the water, and people use under unclear situation, will make troubles to health.

The utility model content

The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of automatic flushing toilet is provided.

The utility model solves the technical scheme that its technical problem adopted: a kind of automatic flushing toilet; Comprise water level detection circuit, infrared pulse radiating circuit and single chip machine controlling circuit; The output signal of said water level detection circuit transfers to circuits for triggering; The output signal of infrared pulse radiating circuit transfers to infrared receiving circuit, and the output signal of said circuits for triggering and infrared receiving circuit is sent to bath drive circuit and alarm circuit through single chip machine controlling circuit control.

Further, said single chip machine controlling circuit and watchdog circuit bidirectional data communication.

Further, said water level detection circuit is made up of the full exploring electrode A of water, lack of water exploring electrode B and anhydrous exploring electrode C.

Basis set became module U1 when further, said circuits for triggering adopted NE555.

Further, said infrared pulse radiating circuit is made up of the output connection infrared-emitting diode VD1 of CD4011 42 input NAND gate CMOS chip IC 3.

Further, said infrared receiving circuit is connected the infrared reception of CX20106 by the output of the phototriode VT1 that matches with infrared-emitting diode VD1 and controls integrated chip IC 4 and constitute.

Through adopting above-mentioned technical scheme; The beneficial effect of the utility model is: the utility model can be after people use toilet auto-flushing; And when the toilet water level drops to setting value; Promptly send alarm sound, the prompting people can not use toilet, have intellectuality, simple, the reliability advantages of higher of circuit.

Description of drawings

Fig. 1 is the frame assumption diagram of the utility model;

Fig. 2 is the circuit theory diagrams of the utility model.

The specific embodiment

Like Fig. 1, shown in Figure 2; A kind of automatic flushing toilet of the utility model; Comprise water level detection circuit 1, infrared pulse radiating circuit 2 and single chip machine controlling circuit 3; The output signal of said water level detection circuit 1 transfers to circuits for triggering 11; The output signal of infrared pulse radiating circuit 2 transfers to infrared receiving circuit 21, and said circuits for triggering 11 are sent to bath drive circuit 31 and alarm circuit 32 through single chip machine controlling circuit 3 controls, said single chip machine controlling circuit 3 and watchdog circuit 4 bidirectional data communications with the output signal of infrared receiving circuit 21.

Said water level detection circuit 1 is made up of the full exploring electrode A of water, lack of water exploring electrode B and anhydrous exploring electrode C, and basis set became module U1 when said circuits for triggering 11 adopted NE555, when the toilet water level is lower than lack of water exploring electrode B; The 2nd pin that basis set becomes module U1 during NE555 is low level through R1 ground connection, and basis set becomes module U1 to be high level output during NE555; This signal is input to the 34th pin I/O end of single-chip microcomputer IC1; After single-chip microcomputer IC1 internal processes is judged,, promote news Chinese percussion instrument BYY and send the alarm sound by its 26th pin output low level; Expression toilet lack of water reminds the guest can not use toilet.

Said infrared pulse radiating circuit 2 is made up of the output connection infrared-emitting diode VD1 of CD4011 42 input NAND gate CMOS chip IC 3; Not circuit F1, F2 and the resistance R 1 of CD4011 42 input NAND gate CMOS chip IC 3, potentiometer RP1, capacitor C 1 are formed a clock pulse generator; CID4011 42 input NAND gate CMOS chip IC 3 include preposition amplification, amplitude limit, bandpass filtering, detection, integration, comparison shaping and ABLC circuit such as (controls of auto brightness level); Said infrared receiving circuit 21 is connected the infrared reception of CX20106 by the output of the phototriode VT1 that matches with infrared-emitting diode VD1 to be controlled integrated chip IC 4 and constitutes, and is connected on the infrared reception of CX20106 and controls the centre frequency (38kHz) that the resistance size of the 1R4 of integrated chip IC 4 the 5th pin has determined bandpass filter; Capacitor C 2, the C3 that is connected on its 2nd pin is preposition negative-feedback electric capacity; Be used for ABLC control and filtering; Under static state; The 7th pin output that integrated chip IC 4 is controlled in the infrared reception of CX20106 is low level, is connected on the infrared reception of CX20106 and controls the phototriode VT1 and the infrared-emitting diode VD1 of the 1st pin input of integrated chip IC 4 and be complementary, at ordinary times; The infrared pulse that infrared-emitting diode VD1 sends shines on the photosurface of phototriode VT1 unobstructedly; Infrared-emitting diode VD1 changes into the corresponding signal of telecommunication with infrared pulse light, and is connected to the 1st pin input that integrated chip IC 4 is controlled in the infrared reception of CX20106, controls signals such as integrated chip IC 4 amplifications, amplitude limit, bandpass filtering, shaping through the infrared reception of CX20106 and handles.

When the people comes to use toilet; Human body has blocked the path of infrared beam; The infrared reception of CX20106 is controlled the output of integrated chip IC 4 and is transmitted high level by low level; This signal is input to the 25th pin I/O end of single-chip microcomputer IC1, after single-chip microcomputer IC1 internal processor is judged, does not send control signal.After people used, the infrared light path no longer was blocked, and infrared pulse light shines again on the plane of illumination of phototriode VT1; The infrared reception of CX20106 is controlled integrated chip IC 4 outputs and is transmitted low level, and the 25th pin I/O end that this signal is input to single-chip microcomputer IC1 is low level signal, after single-chip microcomputer IC1 internal processor is judged; By its 27th pin output high level signal,, make controllable silicon SCR obtain triggering signal through resistance R 4 current limlitings; Promote electromagnetic valve and open bath, through single-chip microcomputer IC1 internal delay time after 10 seconds, the 27th pin output low level signal of single-chip microcomputer IC1; Make controllable silicon SCR turn-off triggering signal; Electromagnetic valve cuts out automatically, stops bath, reaches the purpose of intelligent closet flushing control.
