[0002] The existing flexible pipeline straight discharge closestool generally utilizes the tensile compression characteristic of the rubber bellows to realize the switching between the sewage discharge position and the water seal position. However, this design has some problems. The structural corrugation of the rubber bellows is prone to causing the sewage to be stuck in the corrugation when flushing small-particle sewage. In addition, due to the flushing mode driven by the gravitational potential energy, the flushing force is weak, and it is difficult to make the small-particle sewage separate from the grooves of the bellows, thereby affecting the discharge effect.

When the swing pipe 2 is in the water seal position, the limiting mechanism cooperates with the driving arm 51 in the limiting direction from the water seal position to the drain position; when the swing pipe 2 is in the drain position, the limiting mechanism cooperates with the driving arm 51 in the limiting direction from the drain position to the water seal position.

[0055] Specifically, as shown in Figure 6, the swing pipe 2 is provided with a swing shaft 21 outside the two sides of the width, the swing pipe 2 is C-shaped, the swing shaft 21 is arranged in the middle of the C-shaped, and the swing shaft 21 is rotationally connected with the driving arm 51. The limiting mechanism comprises an upper limiting shaft 22 and a lower limiting shaft 23; the upper limiting shaft 22 is arranged above the swing shaft 21, and the lower limiting shaft 23 is arranged below the swing shaft 21.

[0056] As Figure 4 , the pipe swing assembly further comprises a motor 52 and a support 53, the pair of driving arms 51 are divided into a driving rotary arm 511 and a driven rotary arm 512, the upper limiting shaft 22 and the lower limiting shaft 23 are arranged on the same side of the driving rotary arm 511, and the bottom of the support 53 is provided with a second mounting hole 533 (as Figure 11 , which is fixed on a fixed building, can be fixed on the bottom of a toilet ceramic base 7 or on the ground.

The motor 52 controls the drive arm 51 to continue to swing upward to the water seal position. During the swing of the drive arm 51, the upper limit rotating shaft 22 is rotationally matched with the drive arm 51 through the limiting wheel 24, so as to avoid the movement from being stuck and make the movement more smooth.

The flushing control unit is used to control the timing of the swinging action of the pipeline swinging assembly 5 and the start and stop of the main flushing water path assembly 8 or the rim flushing water path assembly 9.

[0065] In the specific flushing process, the flushing control unit performs the following timing:

[0066] Step 1: The flexible pipeline direct discharge device is in the water seal position, and the flushing control unit opens the rim flushing water path assembly 9 to flush the rim water. When the water level of the ceramic base 7 reaches the predetermined position, the flushing of the rim water is stopped.

[0067] Step 2: The flushing control unit controls the pipeline swinging assembly 5 to swing downward to the sewage discharge position (the flushing control unit controls the motor 52 to rotate, for example, counterclockwise, to drive the rotating arm 511 to swing counterclockwise and drive the swinging pipe 2 to move downward, so that the flexible pipeline direct discharge device reaches the sewage discharge position). Figure 1

[0068] Step 3: The flushing control unit opens the main flushing water path assembly 8 to flush the sewage (the water on the ceramic base is quickly discharged to the sewage pipe 4 under the gravity potential energy and the main flushing water).

[0069] Step 4: After the flushing control unit closes the main flushing water path assembly 8, the flushing control unit controls the pipeline swinging assembly 5 to swing upward to the water seal position (the flushing of the main flushing water is stopped, and the flushing control unit controls the motor 52 to rotate, for example, clockwise, to drive the rotating arm 511 to swing clockwise and drive the swinging pipe 2 to move upward, so that the flexible pipeline direct discharge device reaches the water seal position). Figure 2

[0070] Step 5: The flushing control unit opens the rim flushing water path assembly 9 to supplement the rim water, and the flushing of the rim water is stopped after the water reaches the water seal position.

[0071] The flushing process is repeated in steps 1-5.
