         74 . The toilet according to  claim 73 , wherein the dispenser is configured to work in a first working position, a second working position, and a third working position,
 wherein when the dispenser works in the first working position, the dispenser is in fluid communication with the nozzle cleaning port, and   wherein when the dispenser works in the second working position and the third working position, the dispenser is fluid communication with the water inlet.   
     
     
         75 . The toilet according to  claim 74 , wherein a first flowrate of fluid entering the cleaning pipe via the water inlet when the dispenser works in the second working position is smaller than a second flowrate of the fluid entering the cleaning pipe via the water inlet when the dispenser works in the third working position. 
     
     
         76 . The toilet according to  claim 75 , wherein a pressure generated by the fluid, at the first flowrate, entering the cleaning pipe is not sufficient to push the sliding pipe to a preset position for spraying the fluid to a user, and
 wherein a pressure generated by the fluid, at the second flowrate, entering the cleaning pipe is sufficient to push the sliding pipe to the preset position for spraying the fluid to the user.

 wherein the first flowrate is smaller than the second flowrate.   
     
     
         86 . The method according to  claim 81 , further comprising:
 controlling the dispenser to work in a fourth working position after the second preset time period so as to deliver the fluid, at a third flowrate, from the second outlet of the dispenser to the water inlet via the second pipeline,   wherein a third flowrate is greater than the second flowrate.
