[0068] The design of the plurality of threaded pins 12 increases the connection strength between the sealing cover 11 and the water tank body 1.

[0069] The working principle of the present application will be described below with a preferred embodiment:

[0070] The main flushing pipe 21 is connected with the external toilet bowl, and the external water source enters the water tank body 1 for storage. Under the action of water pressure in the water tank body 1, the cover plate 24 at the top end of the small-urine flushing pipe 22 and the large-urine flushing pipe 23 is in a closed state.

[0071] When it is necessary to flush the small urine in the toilet bowl, the knob 345 is rotated counterclockwise by 90 degrees, the knob 345 abuts against the stop bar 344b, the knob 345 drives the rotating shaft 342a to rotate in the end cover 344 and the shell 341, the twisting disc 342 on the outer wall of the rotating shaft 342a and the positioning pin 343 are offset, at the same time, the elastic members 342b on both sides of the twisting disc 342 are deformed. At this time, the transmission rope 33 connected with the cover plate 24 at the top end of the small-urine flushing pipe 22 is stressed and moves along the fixed pulley 32 to the inner cavity of the main flushing pipe 21, thereby driving the cover plate 24 to open. Under the action of water pressure, the water source enters the main flushing pipe 21 along the small-urine flushing pipe 22 to flush the small urine in the toilet bowl. After use, the elastic members 342b restore the deformation to drive the knob 345 to reset, and the cover plate 24 resets to cap the top end of the small-urine flushing pipe 22.

[0072] When it is necessary to flush the large urine in the toilet bowl, the knob 345 is rotated clockwise by 90 degrees, the knob 345 abuts against the stop bar 344b, at this time, the transmission rope 33 connected with the cover plate 24 at the top end of the large-urine flushing pipe 23 is stressed and moves along the fixed pulley 32 to the inner cavity of the main flushing pipe 21, the cover plate 24 is separated from the large-urine flushing pipe 23, and the water source enters the main flushing pipe 21 along the large-urine flushing pipe 23. Since the height of the water inlet end of the large-urine flushing pipe 23 is lower than that of the small-urine flushing pipe 22, the pressure during flushing of the large urine is greater than that during flushing of the small urine, and the water discharge amount can be greater, so as to flush the large urine in the toilet bowl. After use, the elastic force of the elastic members 342b is used to drive the knob 345 to reset.

[0073] ​Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
