[0035] A flushing port 25 is provided on the side wall of the upper part of the toilet bowl 2, and the flushing port 25 is connected to a water inlet pipe 27 through a second solenoid valve 26, and the second solenoid valve 26 is electrically connected to a controller in the smart toilet; by adopting this structure, when the controller in the smart toilet opens the second solenoid valve, tap water from the water inlet pipe can be flushed out through the flushing port, and at this time, the flushing of the toilet bowl can be achieved; when the controller in the smart toilet closes the second solenoid valve, the flushing port can stop flushing the toilet bowl; in addition, pipe joints are provided on the left and right walls of the outer shell of the smart toilet, and the end of the water inlet pipe away from the second solenoid valve can be connected to the pipe joint on either side of the outer shell according to actual installation requirements, and the pipe joint is finally connected to the angle valve installed on the tap water pipe through a hose.

[0036] When using the present invention, that is, when the user sits on the smart toilet to defecate, the user can start the exhaust mechanism by pressing the exhaust button on the remote control of the smart toilet. After the exhaust mechanism is started, the exhaust fan starts to work, and the first solenoid valve is opened (at this time, the piston is located on the front side of the shell). When the exhaust fan is working, the odor in the toilet bowl can flow through the exhaust port, the first connecting pipe, the three-way, the exhaust chamber, the exhaust fan, the channel, the first solenoid valve and the sewage outlet in sequence and then enter the sewer pipe. When the user finishes defecation, he can press the flush button on the remote control of the smart toilet. The flush button After the button is pressed, the exhaust fan stops working and the first solenoid valve is closed. At the same time, the driving mechanism drives the piston to slide to the rear side of the shell. After the channel on the piston connects the sewage inlet and the sewage outlet, the feces in the toilet bowl can fall into the sewer pipe. After the piston slides to the rear side of the shell, the trigger block on the rack can trigger the proximity switch on the rear side. In this way, the motor in the driving mechanism can stop working. At this time, the second solenoid valve in the smart toilet will open. After the second solenoid valve is opened, the tap water from the water inlet pipe will start to flow. The toilet bowl starts to be flushed. After 5-10 seconds of flushing, the driving mechanism can drive the piston to slide forward and reset. After the piston resets forward, the trigger block on the rack can trigger the proximity switch on the front side. At this time, the motor will stop working, and the second solenoid valve will continue to open for 1-2 seconds to replenish water in the toilet bowl, that is, a water seal can be formed at the leakage port of the toilet bowl; after the smart toilet is flushed, the ozone generator located in the smart toilet starts to work, and the ozone generated by the ozone generator can be discharged through the second connecting pipe, the tee, the first connecting pipe and the exhaust fan. The ozone enters the toilet bowl after entering the mouth. The ozone that enters the toilet bowl can sterilize and disinfect the toilet bowl. After the ozone generator has worked for 30 seconds, the controller in the smart toilet will turn off the ozone generator and at the same time turn on the exhaust mechanism and the first solenoid valve again. After the exhaust mechanism and the first solenoid valve are turned on, the ozone in the toilet bowl can be discharged into the sewer pipe. After the exhaust mechanism and the first solenoid valve are opened for 30 seconds, the controller in the smart toilet will turn off the exhaust mechanism and the first solenoid valve again. After the above steps, the smart toilet completes a working process.
