A conversion cylinder 8 with openings at both ends is rotated between the two sets of cross slides 7, so that the conversion cylinder 8 can rotate relative to the cross slide 7, and the conversion cylinder 8 is connected externally. A waste liquid temporary storage box 9, the rotating shafts at the left and right ends of the conversion cylinder 8 rotate and pass through the cross sliders 7 on both sides respectively, one end of the rotating shaft of the conversion cylinder 8 is connected to a main gear 10, and the corresponding vertical The first motor 11 is installed on the plate 6, and its output shaft end is connected with a driving gear 12. The main gear 10 satisfies that the main gear 10 and the driving gear 12 are meshed and rotated when the conversion cylinder 8 moves to just below the drain hole 2. That is to say, in the process that the conversion cylinder 8 moves longitudinally in the vertical plate 6 along with the cross block 7, when the conversion cylinder 8 moves to just below the drain hole 2, it is also the limit position of the movement of the cross block 7, At this time, the main gear 10 and the driving gear 12 are meshed smoothly, and the first motor 11 here is a self-locking motor, which can ensure that the conversion cylinder 8 is locked in the current position when the conversion cylinder 8 is in this position, and no occurrence of Rotation in the vertical plane, unless the first motor 11 drives it to rotate, as for the locking in the longitudinal direction of the conversion cylinder 8, the present invention relies on the structure of the hydraulic cylinder 22-hydraulic push rod 23 at the other end of the rotating shaft to achieve longitudinal locking , since the hydraulic cylinder 22 has the function of locking the hydraulic push rod 23, it provides a guarantee for the locking of the longitudinal movement of the conversion cylinder 8;

For the excrement that flows out, the intermediate cavity 14 is closed and an air pressure regulating pump 16 is installed in it. The air pressure regulating pump 16 is controlled by the electronic control unit to perform the work of increasing the air pressure and reducing the air pressure. A piston 17 is slidably fitted along the axial direction. The piston 17 and the partition plate form a regulating air chamber 18, and the air tightness of the regulating air chamber 18 is good. The air pressure regulating pump 16 is connected to the regulating air chamber 18 through an air valve. It is satisfied that the air pressure regulating pump 16 drives the piston 17 to move axially by controlling the air pressure of the regulating air chamber 18. When the piston 17 needs to be pushed outward, the general control unit controls the air valve on the air pressure regulating pump 16 to open, and at the same time the air pressure regulating pump 16 The air pipe at the output end inflates the regulating air chamber 18, so the air pressure in the regulating air chamber 18 becomes larger, and pushes the piston 17 to move outward. The rod of the piston 17 extends to the middle cavity 14 and is rotatably connected with a round rod 19 which is hollow inside the entire rod of the piston 17. One end of the rod 19 is connected to a circular nozzle on the side of the piston 17 facing the opening. 20, the water jet of the circular nozzle 20 is opened on the side facing the piston 17, the other end of the circular rod 19 is connected to the water pump 5 and the waste liquid temporary storage tank 9 through a three-way pipe, and the piston The upper end of the 17 is connected with the piston 17 rod. The piston 17 rod slides vertically through the partition and the end extends into the middle cavity 14. At this time, it should be noted that the sliding connection part between the piston 17 rod and the partition must ensure air tightness. To ensure the air tightness, we can set a circle on the baffle plate with rubber rings on the upper and lower sides, and the rubber rings and the piston 17 rod are squeezed together to ensure air tightness. The sewage chamber 15 and the waste liquid temporary storage box 9 There are one-way valves between the waste liquid temporary storage tank 9 and the round rod 19, and between the water pump 5 and the round rod 19.

The operation state is controlled by the electronic control unit. Due to the limited space in the drawings, the hose is not drawn, but it does not mean that there is no such structure. Special description is given here. For those skilled in the art, it is easy to I understand how to connect, so it is not shown. The outlet end of the excretory cavity 13 is connected to a blocking device, so that the blocking device can seal or open the excretory cavity 13 during the rotation process. After the user completes the excretion work , the discharge cavity 13 needs to be rotated to the bottom for collection and cleaning. At this time, during the rotation process, a blocking device is required to effectively block the outlet end to reduce its pollution to other structures of the present invention. Wait until the discharge cavity 13 is rotated to a positive When it is down, the blocking device will completely open the outlet of the excretory cavity 13;
