1. Adding descaling liquid:

firstly, the knob 321 of the sealing cover 3 is rotated to release the fastening state of the cover surface layer 32 and the filling opening 12; then the cover layer 32 drives the sealing part 31 to withdraw from the liquid feeding channel 121 outwards (away from one side of the inner cavity 11), in the withdrawing process, the sealing state of the overflow port 17 is firstly released (as shown in fig. 9), the overflow port 17 is communicated with the inner cavity 11, finally the whole sealing cover 3 is removed (as shown in fig. 10), and the sealing cover 3 is separated from the liquid feeding port 12; then, the descaling liquid is poured into the inner cavity 11 from the liquid adding port 12, and if the descaling liquid overflows the overflow port 17, the excessive part flows out to a specified position (such as a brush ring of a toilet) from the overflow port 17 along the overflow channel; finally, after the liquid is added, the sealing cover 3 is covered on the liquid adding port 12, the sealing part 31 extends into the liquid adding channel 121 and seals the sealing section 1211, the knob 321 is rotated to restore the fastening state of the cover surface layer 32 and the liquid adding port 12, and the inner cavity 11 of the cylinder barrel 1 is sealed and separated from the overflow port 17 (outside);
