  • Hose 4 is disposed in an inclined way and is connected with the drain pipe 111 and the outside sewage pipe.
  • the sewage and the water are directly discharged into the outside sewage pipe through the inclined hose 4 .
  • the drainage is downward instead of upward, and the sewage can be easily flushed away using little water.
  • the outside sewage pipe can be disposed in many ways.
  • the outside sewage pipe is a lower sewage pipe 31 or a rear sewage pipe 32 .
  • the specific type of the sewage pipe is disposed upon the specific installation position of the toilet bowl.

  • the end of hose 4 is connected and fixed with drain pipe 111 and the outside sewage pipe is fixed by a ring hoop.
  • the two ends of hose 4 are respectively provided with fixing slots that extend in the circumference; the water-saving device is also provided with a ring hoop; and the ring hoop is disposed in the fixing slots to fix hose 4 on drain pipe 111 and the sewage pipe.
  • the fixing slots further limit the axial movement of the ring hoop.
  • the fixation is firm; the dismantling is convenient; and the use is simple.
  • the toilet bowl body 1 is provided with a case inside, or the water close body 1 itself is the case.
  • the case conducts the function of fixing rotating shaft 52 .
  • Rotor 51 is rotationally disposed on rotating shaft 52 .
  • rotor 51 is composed of rotating plates which are disposed parallel to each other; the middle parts of the rotating plates have rotating holes through which rotating shaft 52 penetrates through.
  • the first pressing member 53 is a pressing rod; the two ends of the pressing rods are respectively connected with the two rotating plates; and hose 4 extends through the space between the pressing rod and the rotating shaft 52 .
  • the rotator 51 When the rotator 51 rotates towards hose 4 along the pressing rod 4 , the pressing rod presses hose 4 to reduce the cross section of hose 4 and continuously rotates to close hose 4 and in such circumstances, the rotator 51 rotates in the reverse direction to open hose 4 .
  • the rotor 51 is shaped like a rocker on the rotating shaft 52 , alternatively controlling the opening and closing of hose 4 .
  • the rotor 51 in the rocker mode in one embodiment is specially as follows: the rotor 51 is connected with a drive rope 6 which pulls the rotor 51 to rotate; and the drive rope 6 is linked with a switch 21 .
  • hose 4 is closed, and in such circumstances, the first pressing member 53 presses hose 4 .
  • the drive rope 6 drives the rotor 51 to rotate, the flushing water valve opens, the water tank 2 flushes the flushing water chamber 11 , and then hose 4 opens to drain the sewage.
  • the rotor 51 in the rocker mode in another embodiment is as follows: the drive rope 6 is connected to the rear end of the rotor 51 ; the water-saving device is also provided with a reset spring 7 ; one end of the reset spring 7 is connected to the rear end of the rotor 51 , while the other end is fixed on the case.
  • the first pressing member 53 closes hose 4 and the spring is at the normal position.
  • the force acting on the drive rope 6 disappears, and the rotor 51 resets to the original position by the effect of the reset spring 7 .
  • the outer side of the water tank 2 can be provided with a housing through which the drive rope 6 can penetrate, ensuring that the entire toilet bowl has a beautiful appearance.
  • the case is provided with a first fixing block 81 .
  • the first fixing block 81 is disposed on the other side of hose 4 relative to the first pressing member 53 and pressed against hose 4 .
  • the movement of hose 4 is limited by the effect of support of the first fixing block 81 , thus realizing the closing and opening of hose 4 .
  • the water-saving device also comprises a siphon 9 .
  • the siphon 9 is disposed on hose 4 in a reverse “U” shape.
  • the peak of the reverse “U”-shaped siphon 9 disposed is lower than the toilet bowl body 1 but higher than the water level in the flushing water chamber 11 .
  • the siphon 9 may have a smaller inner diameter;
  • the siphon has two functions. One is to generate an absorption force which generates siphonage through the siphon to continuously bring away water (or air) in the toilet bowl when the sewage hose is sealed and the sewage in the lower sewage pipe is pulled downward continuously, thus ensuring smooth sewage discharge.
  • the other is to prevent water leakage.
  • hose 4 is closed, when the toilet bowl leaks water and the water level is higher than the peak of siphon 9 , water flows out from siphon 9 by the effect of the pressure difference. Meanwhile, some sensors can be installed to prompt the users.
  • siphon 9 is closed when hose 4 is used, avoiding the situation that the sewage is shunted by siphon 9 , causes smaller flushing force of hose 4 and results in water waste. Meanwhile, the sewage is also prevented from being clamped in siphon 9 to cause failure of anti-leakage. Therefore, in this embodiment, the rotor 51 also extends to form a rotating end 54 . The top of rotating end 54 is provided with a second pressing member 55 . The second pressing member 55 presses siphon 9 to implement closing and opening of siphon 9 when rotor 51 rotates. In such circumstances, the connecting plates are trifurcate plates, and the principle is similar to that of the first pressing member 53 and therefore is not repeatedly described.
  • hose 4 and siphon 9 are alternatively to be opened and closed, which means that when hose 4 is open, siphon 9 is closed, while when hose 4 is closed, siphon 9 is open. Therefore, when the first pressing member 53 is reset and hose 4 is pressed by the effect of reset spring 7 , the second pressing member 55 turns to the direction away from siphon hose 4 .
  • the case is provided with a second fixing block 82 .
  • the second fixing block 82 is disposed on the other side of siphon 9 relative to the second pressing member 55 .
  • the first fixing block 81 and the second fixing block 82 are a whole body.
  • valve 41 which allows the fluid to flow in one direction.
  • Valve 41 functions as a one-way valve. When discharged, the water flushes open the opening in the middle part of valve 41 . When the toilet bowl is not used, the opening is closed to prevent the serious smell in the sewage pipe from flowing back into the room.
