detailed description

As shown in Figure 1-3, an automatic flushing toilet includes a urinal 3 and a flushing tank 4. The flushing tank 4 is connected to the urinal 3 through a pipeline. A button for a box of water, a first pressure sensing device 1 is provided on both sides of the urinal 3, a second pressure sensing device 2 is provided in front of the urinal 3, and a first flushing switch is respectively provided on the flushing tank 4 The relay 6 and the second flushing switch relay 7, the first flushing switch relay 6 and the second flushing switch relay 7 correspond to the button for flushing half a box of water and the button for flushing a box of water respectively; The pressure sensing device 1 and the second pressure sensing device 2 are connected to the input end of the controller 8 , and the first flush switch relay 6 and the second flush switch relay 7 are connected to the output end of the controller 8 .

Preferably, the flushing tank 4 is further provided with an infrared sensor 5 , and the infrared sensor 5 is connected to the input end of the controller 8 .

Preferably, the first pressure sensing device 1 and the second pressure sensing device 2 include a pressure sensor and a floor mounted on the pressure sensor.

Preferably, the controller 8 is located below the floor.

Described controller can adopt the one-chip computer that model is AT89C2051. The pressure sensor can be a QLM series sensor, and the infrared sensor can be an OS136 series sensor.

The first pressure sensing device 1 and the second pressure sensing device 2 are installed on both sides and front of the urinal to detect the pressure of the human body on the ground, and an infrared sensor 5 is installed on the water tank to set the pressure detected by the first pressure sensing device 1. The signal is a, a=1 when there is pressure, a=0 when there is no pressure; the pressure signal detected by the second pressure sensing device 2 is b, b=1 when there is pressure, and b=0 when there is no pressure; the infrared sensor 5 detects The signal is c, c=1 when there is a signal, and c=0 when there is no signal. The sensing range of the infrared sensor is approximately 0.75m. There is no induction signal when the person stands under the steps, but there is an induction signal when the person is on the steps.

The signal values detected by the first pressure sensing device 1 , the second pressure sensing device 2 and the infrared sensor 5 are converted into standard signals and input to the controller 8 . After the controller 8 receives the signal, it judges the state of the toilet, and then outputs a signal to control the first flush switch relay 6 and the second flush switch relay 7 to flush. The specific working conditions are as follows:

When someone is standing on the steps to urinate, the first pressure sensing device 1 detects a signal value a=0, the second pressure sensing device 2 detects a signal value b=1, the infrared sensor 5 detects a signal value c=1, and the control The device records the signal at this time, and controls the first flushing switch relay 6 not to act. When a person leaves after going to the toilet, the first pressure sensing device 1 detects a signal value a=0, the second pressure sensing device 2 detects a signal value b=0, the infrared sensor 5 detects a signal value c=0, the controller and Compared with the signal recorded just now, the first flushing switch relay 6 is controlled to act, and half a tank of water is started to be flushed.

When a person stands on the urinal 3 and prepares to defecate, the first pressure sensing device 1 detects a signal value a=1, the second pressure sensing device 2 detects a signal value b=0, and the infrared sensor 5 detects a signal value c=1 , the controller records the signal at this time, and controls the second flushing switch relay 7 not to act. When a person leaves after going to the toilet and walks down the steps, the first pressure sensing device 1 detects a signal value of a=0, the second pressure sensing device 2 detects a signal value of b=0, and the infrared sensor 5 detects a signal value of c= 0, the controller compares with the signal recorded just now, controls the action of the second flushing switch relay 7, and starts flushing the whole tank of water.

When there is no pre-signal input, the detection value of the infrared sensor 5 is c=0, and the detection values of the first pressure sensing device 1 and the second pressure sensing device 2 are both 0, then the controller has no signal output.

When the detection value of the infrared sensor 5 is c=0, and the detection value of the first pressure sensing device 1 or the second pressure sensing device 2 is 1, it is an abnormal state, and the controller has no signal output.
