[0003] Currently, after the toilet is used, it is necessary to discharge the chips of the excrement therein to ensure the cleanliness of its inner wall. Generally, water or a slide valve is used to discharge the excrement. However, during the sewage discharge, there may be a leakage phenomenon of the slide valve rod when the gas in the slide valve enters and exits, which will reduce the impact force and thus reduce the sewage discharge capacity. Content of the Utility Model
[0004] In order to solve the above problems, the purpose of the utility model is to provide a slide valve for a train vacuum toilet to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the utility model provides a slide valve for a train vacuum toilet, which includes a toilet body. A fecal collection tank is arranged at the top of the toilet body. Two support plates are fixedly installed on the inner wall of the toilet body, and slide valve bodies are arranged on the tops of the two support plates.
[0006] A gas guiding mechanism is arranged inside the slide valve body, and the gas guiding mechanism includes a slide valve rod, a guide rail, a slide valve ring, an eccentric wheel, a rod port, and a driving shaft. The guide rail is rotatably connected to the inner wall of the slide valve body. One side of the inner wall of the slide valve body is rotatably connected to a driving shaft that penetrates and extends outside the slide valve body. An eccentric wheel is fixedly installed at one end of the driving shaft located inside the slide valve body. A slide valve ring is arranged on the outer ring of the eccentric wheel. A slide valve rod that penetrates and extends outside the guide rail is arranged on the outer ring of the slide valve ring. A rod port is arranged on the outer ring of the slide valve rod.
[0007] In one example, a through port is arranged at the top end of the slide valve rod.
[0008] In one example, an exhaust pipe is fixedly arranged on the outer ring of the slide valve body. The exhaust pipe penetrates and extends into the fecal collection tank, and a pipe head is arranged at one end of the exhaust pipe located in the fecal collection tank.
[0009] In one example, an air inlet is arranged at one end of the slide valve body, and the size of the air inlet is adapted to the size of the slide valve rod.
[0010] In one example, a motor is fixedly installed on one side of the inner wall of the toilet body, and rotating shafts are fixedly installed on the output shafts of the two motors.
[0011] In one example, the other ends of the two rotating shafts away from the motors are fixedly connected to one end of the drive shaft outside the slide valve body.
[0012] The slide valve for a train vacuum toilet proposed by the present utility model can bring the following beneficial effects:
[0013] For the slide valve for a train vacuum toilet, through the movement of the slide valve rod in the air guiding mechanism, when the rod port on the slide valve rod is separated from the guide rail, at this time, the air inlet on the slide valve body introduces gas and then transports it through the through port on the slide valve rod into the slide valve rod, and then introduces it through the rod port. When the movement of the slide valve rod drives the rod port to be located within the guide rail, the rod port can be sealed at this time, avoiding air leakage during subsequent movement. At this time, continue to move, and the gas therein will be compressed, and then transported to the nozzle through the exhaust pipe and sprayed out to clean the fecal collection tank and prevent excrement from sticking.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] In order to more clearly illustrate the overall concept of the present utility model, the following will be described in detail by way of examples in conjunction with the drawings of the specification.
[0022] Such as Figures 1 to 5As shown in the figure, an embodiment of the present utility model provides a slide valve for a train vacuum toilet, which includes a toilet body 1. A toilet bowl 15 is provided at the top of the toilet body 1. Two support plates 13 are fixedly installed on the inner wall of the toilet body 1. Slide valve bodies 2 are provided at the tops of the two support plates 13.
[0023] A gas guiding mechanism is provided inside the slide valve body 2. The gas guiding mechanism includes a slide valve rod 4, a guide rail 5, a slide valve ring 6, an eccentric wheel 7, a rod orifice 8, and a drive shaft 14. The guide rail 5 is rotatably connected to the inner wall of the slide valve body 2. One side of the inner wall of the slide valve body 2 is rotatably connected to a drive shaft 14 that penetrates and extends outside the slide valve body 2. An eccentric wheel 7 is fixedly installed at one end of the drive shaft 14 inside the slide valve body 2. A slide valve ring 6 is provided on the outer ring of the eccentric wheel 7. A slide valve rod 4 that penetrates and extends outside the guide rail 5 is provided on the outer ring of the slide valve ring 6. A rod orifice 8 is provided on the outer ring of the slide valve rod 4.
[0024] Specifically, a through port 16 is provided at the top end of the slide valve rod 4. Gas is introduced into the slide valve rod 4 through the through port 16 and then discharged through the rod orifice 8.
[0025] Specifically, an exhaust pipe 9 is fixedly provided on the outer ring of the slide valve body 2. The exhaust pipe 9 penetrates and extends into the toilet bowl 15. A pipe head 10 is provided at one end of the exhaust pipe 9 located in the toilet bowl 15. Compressed gas is transmitted through the exhaust pipe 9 and then sprayed into the toilet bowl 15 through the pipe head 10.
[0026] Specifically, an air inlet 3 is provided at one end of the slide valve body 2. The size of the air inlet 3 is adapted to the size of the slide valve rod 4. Air enters the slide valve body 2 through the air inlet 3.
[0027] Specifically, a motor 12 is fixedly installed on one side of the inner wall of the toilet body 1. Rotating shafts 11 are fixedly installed on the output shafts of the two motors 12. The motors 12 drive the rotating shafts 11 to rotate, which drives the drive shaft 14 to rotate, and then drives the eccentric wheel 7 to rotate.
[0028] Specifically, the other ends of the two rotating shafts 11 away from the motors 12 are fixedly connected to the end of the drive shaft 14 outside the slide valve body 2. The rotation of the drive shaft 14 drives the eccentric wheel 7 to rotate, and the movement of the slide valve ring 6 is achieved.
[0029] Working principle: It is necessary to exhaust the inside of the fecal collection tank 15. At this time, start the motor 12 to drive the rotation of the rotating shaft 11, which will drive the rotation of the drive shaft 14. At this time, the eccentric wheel 7 can be driven to perform eccentric motion, which will drive the slide valve rod 4 to move through the slide valve ring 6. When the rod port 8 on the slide valve rod 4 is separated from the guide rail 5, the air inlet 3 of the slide valve body 2 will intake air at this time, and then it will be transported into the slide valve rod 4 through the through port 16, and then transported into the slide valve body 2 through the rod port 8. When the slide valve rod 4 continues to move and drives the rod port 8 to move into the guide rail 5 and be sealed, the gas inside the slide valve body 2 can be compressed at this time, and the gas is transported to the nozzle 10 through the exhaust pipe 9 and ejected, so as to discharge the excrement in the fecal collection tank 15.
