Detailed Description
As shown in fig. 1 to 3, the method for disinfecting and flushing a toilet without cleaning the toilet comprises the following steps:
firstly, a switching power supply 102 is connected with an electric control device 101, the electric control device 101 is connected with a pyroelectric sensor 104,
the pyroelectric sensor 104 transmits the detected human body approach signal to a first pin P1.1 of a singlechip STC15W408AS in the electric control device 101, at the moment, P1.1 is set as an input pin of A/D conversion, an adjustable threshold potential is set at a second pin P1.2 of the singlechip, at the moment, P1.2 is also set as the input pin of A/D conversion, then a voltage comparison module is arranged in a program memory of the singlechip, the voltage of the human body approach signal is compared with the threshold potential, when the human body approach signal is higher than the threshold potential, the voltage comparison module outputs an execution instruction, and a third pin P1.3 and a fourth pin P1.4 of the singlechip are driven to be in high level;
the P1 port of the single chip microcomputer STC15W408AS has 10-bit A/D conversion function, and the application precision is enough in the invention.
A status flag program module is set to "manned" status at this time;
step two, a third pin of the singlechip drives the ozone generator 105 and a fourth pin drives the air pump 103, and the air pump presses the ozone output by the ozone generator to an aerator 106 in a water tank 112 through a fluorine rubber tube 111;
the air pump 103 has an air inlet 108.
Step three, the aerator distributes ozone gas into the water storage of the water tank through the micropores of the aerator;
and step four, stopping the ozone generator and the air pump after the ozone generator and the air pump work for 3-10 minutes so as to avoid over-production of ozone.
Step five, next; when a user drains water and flushes a toilet, the singlechip detects the first pin of the singlechip all the time, the potential of the first pin is seen to be high or low, when the potential of the first pin of the singlechip is lower than the threshold potential, the user leaves the toilet, and the singlechip sets the state flag program module to be in an 'unmanned' state;
and step six, the single chip microcomputer always detects a first pin of the single chip microcomputer connected with the pyroelectric sensor to see whether a person approaches the pyroelectric sensor.
In the method, the water level sensor is arranged in the water tank of the singlechip, the output of the water level sensor is connected with the fifth pin of the singlechip, and the ozone generator and the air pump can be started to operate only when the fifth pin of the singlechip is at a high level.
In the method, the threshold potential in the step one is adjusted to be lower than the voltage of the human body approach signal when the user approaches the pyroelectric sensor for 1.5 m.
In the method, the induction angle of the pyroelectric sensor is 90-120 degrees, and the pyroelectric sensor can be detected from any direction regardless of the direction from which a user comes.
In the method, the single chip microcomputer in the sixth step always detects the first pin of the single chip microcomputer connected with the pyroelectric sensor 10, whether a person approaches the pyroelectric sensor 104 or not is detected, a timer is started, when the pyroelectric sensor 104 does not detect the approach of the person within 30 minutes, the electric control device 101 enters an energy-saving state, the pyroelectric sensor 104 cannot stop supplying power because the pyroelectric sensor 104 needs 50 seconds of initialization time when being put into operation, and only the pyroelectric sensor 104 works in the energy-saving state because the current of the pyroelectric sensor 104 is very small during the operation.
At which time the indicator light 107 is dimmed.
The aerator 106 is a microporous device, and the gas is sent to the aerator by pressure, and is uniformly diffused from a plurality of micropores and fully mixed with water, so as to achieve the purpose of disinfection and sterilization.
