When the user sits on the cushion 3, the wound at the anus can be fully exposed, and the wound is inside the cavity 2. An installation cavity 4 is opened on one side inside the base 1, and the installation cavity 4 is communicated with the cavity 2. A cleaning mechanism 5 is set inside the installation cavity 4, and the cleaning mechanism 5 is installed at an angle. The spray end of the cleaning mechanism 5 extends to the inside of the cavity 2, and the spray hole of the spray end faces upward. The water sprayed from the spray hole of the spray end rinses the wound of the user, so that the user can independently complete the cleaning of the wound at the anus.

[0034] When the water sprayed from the spray end of the cleaning mechanism 5 is used to rinse the wound of the user, the rinsed water will fall into the cavity 2. Therefore, a drainage channel 6 is provided at the lowest point below the cavity 2 to discharge the contaminated water inside the cavity 2.

[0035] Through the above arrangement, when the user needs to wash the wound at the anus, he only needs to sit on the cushion 3 so that the anus is fully exposed and the anus wound faces downward. At this time, the wound is washed by spraying water through the spray end of the cleaning mechanism 5.

The water inlet 17 can be connected to the inside of the cleaning water tank 54 through a water pipe. In addition, the driving push rod 55 is used to control the movement of the pressurizing piston 16, and the driving push rod 55 is specifically installed on the outer wall of the closed end of the outer tube 51.

[0048] Specifically, milk Figure 3 and Figure 7 As shown, a telescopic cylinder 18 is fixedly provided on the outer wall of one side of the closed end of the outer tube 51, and the telescopic cylinder 18 is arranged below the driving push rod 55. Through holes 41 are opened at both ends of the telescopic cylinder 18, and a telescopic piston 20 is slidably provided inside the telescopic cylinder 18, and a telescopic rod 19 is fixedly provided on the side of the telescopic piston 20 facing the outer tube 51, one end of the telescopic rod 19 passes through the closed end side wall of the outer tube 51 and extends to the inside of the outer tube 51, and the end of the telescopic rod 19 located inside the outer tube 51 is connected to the pressurizing piston 16. It should be noted that the insertion point between the telescopic rod 19 and the outer tube 51 is set as a sliding seal, and the telescopic rod 19 and the through hole 41 are also set as a sliding seal, and a connecting rod 21 is fixedly provided on the other side of the telescopic piston 20, and the other end of the connecting rod 21 is fixedly connected to one end of the telescopic shaft of the driving push rod 55, so that the telescopic piston 20 can move in the same direction as the telescopic shaft of the driving push rod 55.

[0049] Through the above arrangement, when flushing is required, the pressurizing piston 16 is moved toward the open end by driving the push rod 55, and then the pressurizing piston 16 moves in the inner cavity of the outer tube 51 to generate negative pressure, and the cleaning water inside the cleaning water tank 54 is sucked into the inner cavity of the outer tube 51 through the water inlet 17, and then the pressurizing piston 16 is moved toward the closed end by driving the push rod 55, and then the cleaning water inside the inner cavity of the outer tube 51 is discharged from the water inlet 15 into the inner tube 52 through the pressurizing piston 16, and the water entering the inner tube 52 pushes the piston column 533, so that the nozzle body 532 extends out and extends into the cavity 2.

[0050] After the flushing work is completed, in order to reset the piston rod 533, the nozzle body 532 can be retracted into the inner tube 52, and a sleeve 22 is further provided below the telescopic cylinder 18. An air hole 23 is provided at one end of the sleeve 22 away from the outer tube 51, and the sleeve 22 is concentrically arranged with the outer tube 51, the inner tube 52 and the connecting tube 531, and one end of the sleeve 22 is fixedly connected to one end of the outer tube 51, and a linkage rod 24 is provided inside the sleeve 22, and the linkage rod 24 slides through the outer tube 51 and the inner tube 52 toward one end of the outer tube 51. The outer wall of the closed end extends to the interior of the inner tube 52, and the joint between the linkage rod 24 and the outer tube 51 and the inner tube 52 is configured to be in a sliding seal fit. One end of the linkage rod 24 located inside the inner tube 52 is fixedly connected to one end of the center column 92, and the other end of the linkage rod 24 is fixedly provided with a linkage piston 25, and the outer circumferential wall of the linkage piston 25 is in a sliding seal fit with the inner wall of the sleeve 22. In addition, a liquid inlet pipe 42 is connected between the telescopic cylinder 18 and the sleeve 22, and the liquid inlet pipe 42 is configured to be adjacent to the closed end of the outer tube 51.

[0051] Through the above arrangement, when flushing is required, the driving push rod 55 is started to extend the telescopic shaft inside the driving push rod 55, and the extension of the telescopic shaft inside the driving push rod 55 drives the connecting rod 21 to move in the same direction, thereby making the telescopic piston 20 move in the same direction. The movement of the telescopic piston 20 in the same direction will move the telescopic rod 19 in the same direction, and the telescopic rod 19 drives the pressurizing piston 16 to move toward the closed end of the outer tube 51, and then the pressurizing piston 16 discharges the cleaning water inside the inner cavity of the outer tube 51 into the inner tube 52 through the water inlet 15, and the telescopic piston 20 will gradually move away from the liquid inlet pipe 42 while moving with the telescopic rod 19, thereby reducing the water pressure on one side of the linkage piston 25 inside the sleeve 22, and after the cleaning liquid enters the inner tube 52, it will push the piston column 533 toward the open end, and the movement of the piston column 533 will synchronously drive the linkage rod 24 and the linkage piston 25 to move in the same direction, so that the sleeve The liquid inside the tube 22 enters the telescopic cylinder 18. After that, when the piston column 533 contacts the limit ring 7, the nozzle body 532 extends out and is located inside the cavity 2. After the flushing work is completed, the telescopic shaft of the driving push rod 55 is contracted, so that the telescopic piston 20 moves in the same direction, and then the telescopic piston 20 can discharge the liquid inside the telescopic cylinder 18 into the sleeve 22 through the liquid inlet pipe 42, and move the linkage piston 25 toward the air hole 23 through the water pressure, so that the linkage piston 25 can drive the piston column 533 to move in the same direction through the linkage rod 24, so that the nozzle body 532 can be contracted to the inside of the inner tube 52. At the same time, when the telescopic piston 20 moves, the telescopic piston 20 will drive the telescopic rod 19 to move in the same direction, so that the telescopic rod 19 drives the pressurizing piston 16 to move toward the open end, and then the cleaning water inside the cleaning water tank 54 is sucked into the outer tube 51 through the water inlet 17 for the next flushing.

[0052] It should be noted that when the piston column 533 contacts the limit ring 7 and the nozzle body 532 extends out and is located inside the cavity 2, the linkage piston 25 is located on the side of the opening of the liquid inlet pipe 42 inside the sleeve 22 facing the air inlet hole 23, so that when the liquid inside the subsequent telescopic cylinder 18 enters the sleeve 22 through the liquid inlet pipe 42, the linkage piston 25 can be moved toward the air inlet hole 23, so that the piston column 533 can move in the same direction, so that the nozzle body 532 can be retracted into the inner tube 52. When the nozzle body 532 is retracted into the inner tube 52 and the linkage piston 25 contacts one end of the air hole 23 of the sleeve 22, the telescopic piston 20 is located on the side of the opening of the liquid inlet pipe 42 inside the telescopic cylinder 18 facing the air hole 23, so that the liquid inside the subsequent sleeve 22 can enter the telescopic cylinder 18.

[0053] In order to allow the nozzle body 532 to extend into the cavity 2 so that cleaning fluid can be sprayed from the spray hole of the nozzle body 532, when the telescopic shaft of the driving push rod 55 is extended, the pressurizing piston 16 is driven to move toward the closed end through the telescopic rod 19, so that the pressurizing piston 16 can add the cleaning fluid inside the outer tube 51 into the inner tube 52 through the first water inlet, and push the piston column 533 toward the open end. It should be noted that when the piston column 533 contacts the limiting ring 7, the nozzle body 532 is extended into the cavity 2. At this time, the pressurizing piston 16 is located in the middle section of the outer tube 51, and the pressurizing piston 16 is spaced a distance from the closed end, so that the pressurizing piston 16 can continue to move toward the closed end and pressurize the water inside the inner tube 52, thereby spraying it out through the spray hole of the nozzle body 532.

[0054] When flushing the wound, since the liquid spraying end of the cleaning mechanism 5 is inside the cavity 2, it is inevitable that the flushing water will splash onto the liquid spraying end of the cleaning mechanism 5 after flushing the wound, thereby contaminating the liquid spraying end of the cleaning mechanism 5, affecting the subsequent cleaning effect, and even causing the problem of wound infection.

[0055] Therefore, if Figure 3 and Figure 8As shown, a sealing disk 26 is fixedly sleeved on the outer wall of the open end of the inner tube 52, and the sealing disk 26 is located on the side of the pressurizing piston 16 facing the open end, and the outer circumferential outer wall of the sealing disk 26 is fixedly connected to the inner wall of the outer tube 51, and a limiting column 27 is arranged between the sealing disk 26 and the pressurizing piston 16, and the space between the pressurizing piston 16 and the sealing disk 26 is set as a cleaning chamber 28, and a water inlet 29 is fixedly arranged on the outer wall of the outer tube 51 in the cleaning chamber 28 section, and the water inlet 29 is communicated with the inside of the cleaning chamber 28, There are multiple water inlet ports 3 29, which are set to unidirectional flow, and the specific flow direction is from the outside of the outer tube 51 to the inside. The water inlet port 3 29 is connected to the cleaning water tank 54 through a hose, and correspondingly, a cleaning port 30 is fixedly connected and connected to the outer wall of the inner tube 52 in the cleaning chamber 28 section, and there are multiple cleaning ports 30, which are set around the outer circumferential wall of the inner tube 52, and the cleaning port 30 is also set to unidirectional flow, specifically, from the cleaning chamber 28 to the inside of the inner tube 52.

[0056] Through the above arrangement, when cleaning work is required, the pressurizing piston 16 moves toward the closed end, the pressurizing piston 16 will make the inside of the cleaning chamber 28 under negative pressure and suck the cleaning water inside the cleaning water tank 54 into the cleaning chamber 28 through the water inlet 29, and then after completing the cleaning work, the pressurizing piston 16 moves toward the open end. At this time, the pressurizing piston 16 can spray the cleaning liquid inside the cleaning chamber 28 into the inner tube 52 through the multiple cleaning ports 30 arranged around it. At the same time, the nozzle body 532 and the connecting pipe 531 inside the inner tube 52 are shrinking, and then when the nozzle body 532 and the connecting pipe 531 shrink, the cleaning liquid sprayed through the cleaning port 30 flushes and cleans the nozzle body 532 and the connecting pipe 531, and the cleaning liquid flows out through the open end.

[0057] However, simply flushing the nozzle body 532 and the connecting tube 531 will result in an insufficient cleaning effect. The nozzle body 532 needs to be disinfected to avoid infection when the wound is subsequently flushed. Therefore, a closing component 31 is provided at the open end of the inner tube 52, and the closing component 31 is set to an openable and closable state. The open end of the inner tube 52 can be closed or opened through the closing component 31. After the flushing work of the nozzle body 532 is completed, the opening at one end of the inner tube 52 can be closed, and then disinfectant can be added into the inner tube 52 to immerse and disinfect the nozzle body 532 and the connecting tube 531 to improve the cleaning effect.

[0058] like Figure 2 , such as 3, Figure 8 , Fig. 9 and Fig.10As shown, a water pipe joint 32 is installed on the outer circumferential outer wall of the outer tube 51 in the cleaning chamber 28 section. In addition, a disinfection water tank 40 is arranged inside the installation chamber 4, and the water pipe joint 32 can be connected to the disinfection water tank 40 through a hose, and liquid is supplied to the water pipe joint 32 through a water pump, and then the disinfectant is added into the cleaning chamber 28 and enters into the inner tube 52 through the cleaning port 30 for immersion disinfection.

[0059] The closing component 31 includes a closing portion 33 and an opening and closing portion 34, wherein the closing portion 33 is arranged at one end of the outer tube 51 having an opening, and an extension channel 333 is arranged inside the closing portion 33, and the extension channel 333 is arranged to be in an openable and closable state for opening or closing the opening of the inner tube 52, and the opening and closing of the extension channel 333 inside the closing portion 33 is controlled by the opening and closing portion 34.

[0060] Through the above arrangement, after the nozzle body 532 is retracted into the inner tube 52, the extension channel 333 inside the closing part 33 is closed, and then the liquid inlet part is filled with liquid, so that the nozzle body 532 and the connecting tube 531 are immersed in the disinfectant for immersion disinfection, thereby improving the disinfection effect. When flushing is required, the extension channel 333 of the closing part 33 is opened, and the piston column 533 is extended from the opening of the inner tube 52 and the extension channel 333, and the internal disinfectant is discharged at the same time.

[0061] Specifically, the sealing portion 33 includes a fixed disk 331, a movable disk 332, an extension channel 333 and a sealing baffle 334, wherein the fixed disk 331 is concentric with the outer tube 51, and the fixed disk 331 is fixedly arranged in the inner cavity of the open end of the outer tube 51, and a slide groove 35 is opened inside the fixed disk 331, and a plurality of slide grooves 35 are arranged. In this embodiment, five slide grooves 35 are arranged in a circular array with the center of the fixed disk 331 as the center and in a radial shape, and the fixed disk 331 A movable disk 332 is also provided on one side, and an extension channel 333 is transversely penetrated at the center of the movable disk 332 and the fixed disk 331, and the inner tube 52 is concentrically arranged with the movable disk 332. The movable disk 332 is rotatably sleeved on the outside of the open end of the inner tube 52 through the extension channel 333, so that the interior of the inner tube 52 is connected with the interior of the extension channel 333, and a sealing baffle 334 is also provided between the movable disk 332 and the fixed disk 331, and the number of the sealing baffles 334 is the same as the number of the slide grooves 35.

[0062] In the present embodiment, five sealing baffles 334 are arranged in a circular array with the center of the fixed disk 331 as the center, and the sealing baffles 334 are arranged in a fan shape. The five sealing baffles 334 move centripetally and merge to form a circle. The circle formed after the five sealing baffles 334 merge is concentric with the movable disk 332 and the fixed disk 331 and closes the extension channel 333 between the movable disk 332 and the fixed disk 331. In order to allow the five sealing baffles 334 to merge or move radially, a plug-in shaft 36 is fixedly provided on one side of the sealing baffle 334 facing the fixed disk 331, and the plug-in shaft 36 is movably plugged into the inside of the slide groove 35. The sealing The movement of the baffle 334 is limited. In addition, a drive shaft 38 is fixedly arranged on the side of the sealing baffle 334 facing the movable disk 332, and correspondingly, a cam groove 37 is opened inside the movable disk 332, and the number of the cam grooves 37 is the same as that of the sealing baffle 334. The cam groove 37 is arranged in an arc shape, and the drive shaft 38 is movably inserted inside the cam groove 37. By rotating the movable disk 332, the five sealing baffles 334 are made to move centripetally or radially through the cooperation of the cam groove 37 and the drive shaft 38, so that the five sealing baffles 334 are merged or opened, and the extension channel 333 is closed or opened, so as to achieve the purpose of closing and opening the opening of the inner tube 52.

[0063] It should be noted that the two side end surfaces of the sealing baffle 334 are respectively in contact with the movable disk 332 and the fixed disk 331 , and a sealing ring is provided between the outer wall of the inner tube 52 and the inner wall of the extension channel 333 .

[0064] Through the above arrangement, when performing flushing, the movable disk 332 is rotated to separate the sealing baffle 334 to open the extension channel 333, and then the piston column 533 moves to discharge the internal disinfectant through the extension channel 333, and the nozzle body 532 is extended to perform flushing. After the flushing work is completed, the nozzle body 532 shrinks to the inside of the inner tube 52, and then the sealing baffle 334 moves centripetally and merges to close the extension channel 333, so that the nozzle body 532 and the connecting tube 531 are in a closed chamber, and then disinfectant is added for immersion disinfection.

[0065] The opening and closing part 34 includes a rotating shaft 341, a gear ring 342, a gear 343 and a conversion member 344, wherein the rotating shaft 341 is rotatably arranged inside the fixed disk 331, and the outer circumferential outer wall of the movable disk 332 is fixedly provided with a gear ring 342, and the gear ring 342 is provided with a section, and the outer wall of the rotating shaft 341 is fixedly sleeved with a gear 343, and the teeth of the gear 343 and the gear ring 342 are meshed with each other, and the rotating shaft 341 is rotationally controlled by the conversion member 344, and the conversion member 344 is specifically configured to convert the lateral movement of the pressurizing piston 16 into the circumferential rotation of the rotating shaft 341.

[0066] Then, the rotating shaft 341 is rotated by the lateral movement of the pressurizing piston 16 , and the movable disk 332 is driven to rotate by the cooperation of the gear 343 and the gear ring 342 , so that the extension channel 333 is opened or closed.

[0067] It should be noted that when the flushing operation is performed, before the nozzle body 532 moves, the extension channel 333 is opened, and when the nozzle body 532 shrinks, after the nozzle body 532 is completely shrunk into the inner tube 52, the extension channel 333 is closed. Therefore, the conversion member 344 is configured to include a spiral groove 441, a spiral rod 442, a limit plate 443, an insertion rod 444, a positioning ring 445, a spring 446 and a push rod 447, wherein the spiral groove 441 is opened inside the rotating shaft 341, and the spiral rod 442 is inserted into the spiral groove 441. The spiral rod 442 can move horizontally inside the spiral groove 441 to drive the rotating shaft 341 to rotate, and the other end of the spiral rod 442 is fixedly provided with a limit plate 443, and one side of the limit plate 443 is fixedly provided with an insertion rod 444, and the insertion rod 444 extends through the sealing disk 26 to the inside of the cleaning chamber 28, and the insertion point of the plug rod 444 and the sealing disk 26 is slidingly sealed. In addition, a positioning ring 445 is sleeved on the outside of the spiral rod 442, and the outer wall of the positioning ring 445 is fixedly connected to the inner wall of the outer tube 51. A spring 446 is provided between the positioning ring 445 and the limit plate 443, and the spring 446 is sleeved on the outside of the spiral rod 442. The limit plate 443 is rebounded toward the sealing disk 26 by the spring 446, so that the limit plate 443 abuts against one side of the sealing disk 26. Therefore, when it is necessary to rotate the movable disk 332 and thus open or close the extension channel 333, it is only necessary to push the insertion rod 444 so that the insertion rod 444 drives the spiral rod 442 to move and insert inside the spiral groove 441, thereby driving the rotating shaft 341 to rotate, and driving the movable disk 332 to rotate through the cooperation of the gear 343 and the gear ring 342. In order to enable the movement of the pressurizing piston 16 to control the opening and closing of the extension channel 333, a push rod 447 is fixedly provided at one end of the telescopic rod 19 connected to the pressurizing piston 16, and the other end of the push rod 447 passes through the pressurizing piston 16 and extends to the interior of the cleaning cavity 2. The push rod 447 is located inside the cleaning cavity 2 and fits with the insertion rod 444.

[0068] It should be noted that when the insertion rod 444 moves toward the closed end of the outer tube 51, the extension channel 333 is opened, and when the insertion rod 444 moves toward the open end, the extension channel 333 is closed. When the nozzle body 532 shrinks to the inside of the inner tube 52, the pressurizing piston 16 contacts the limiting column 27. At this time, the push rod 447 contacts the insertion rod 444, and the spring 446 is compressed. When the pressurizing piston 16 moves toward the closed end, the push rod 447 moves with the telescopic rod 19, and the push rod 447 is separated from the insertion rod 444. The insertion rod 444 is moved toward the closed end by the action of the spring 446, thereby opening the extension channel 333.

[0069] In addition, the telescopic rod 19 and the side facing the pressurizing piston 16 fit each other, and a push rod 447 is fixedly provided at one end of the telescopic rod 19, and the push rod 447 slides through the pressurizing piston 16, and the insertion part of the push rod 447 and the inside of the pressurizing piston 16 is set as a sliding seal, and a top plate 39 is fixedly provided at one end of the push rod 447 located inside the cleaning chamber 28, and the top plate 39 fits with the insertion rod 444, and the outer diameter of the top plate 39 is larger than the outer diameter of the push rod 447. Therefore, when the telescopic rod 19 moves toward the closed end, it will first drive the push rod 447 to move, and the movement of the push rod 447 makes the top plate 39 and the insertion rod 444 Separation, at this time, the insertion rod 444 moves due to the rebound of the spring 446, thereby opening the extension channel 333. In this process, the pressurizing piston 16 remains stationary to prevent the pressurizing piston 16 from moving and squeezing the cleaning liquid into the inner tube 52, so that only after the extension channel 333 is opened, the pressurizing piston 16 will move under the drag of the top plate 39, thereby squeezing the water inside the outer tube 51 into the inner tube 52, so that after the extension channel is opened, the piston column 533 inside the inner tube 52 will be pushed, and the soaking disinfectant inside the inner tube 52 will be discharged through the extension channel 333.

[0070] The principle of the present invention is as follows: when the present invention is in use, first ensure that the water inlet 2 17 is connected to the cleaning water tank 54, the water inlet 3 29 is connected to the cleaning water tank 54, and the water pipe joint 32 is connected to the disinfection water tank 40, and then start the driving push rod 55. By starting the driving push rod 55, the telescopic shaft inside the driving push rod 55 is extended, and the extension of the telescopic shaft inside the driving push rod 55 drives the connecting rod 21 to move in the same direction, thereby making the telescopic piston 20 move in the same direction. The movement of the telescopic piston 20 in the same direction will move the telescopic rod 19 in the same direction, and the telescopic rod 19 drives the pressurizing piston 16 to move toward the closed end of the outer tube 51, and then the pressurizing piston 16 discharges the cleaning water inside the inner cavity of the outer tube 51 from the water inlet 15 into the inner tube 52. As the telescopic piston 20 moves with the telescopic rod 19, it will gradually move away from the liquid inlet pipe 42, thereby reducing the water pressure on the side of the linkage piston 25 inside the sleeve 22. After the cleaning liquid enters the inner tube 52, it will push the piston column 533 toward the open end. The movement of the piston column 533 will synchronously drive the linkage rod 24 and the linkage piston 25 to move in the same direction, so that the liquid inside the sleeve 22 enters the telescopic cylinder 18. After that, when the piston column 533 contacts the limit ring 7, the nozzle body 532 extends out and is inside the cavity 2. Then, the pressurizing piston 16 continues to move to squeeze the cleaning liquid into the connecting tube 531 through the flow channel 10, and then enters the nozzle body 532 from the connecting tube 531 for spraying. After the washing work is completed, the telescopic shaft of the driving push rod 55 is retracted, so that the telescopic piston 20 moves in the same direction, and then the telescopic piston 20 can discharge the liquid in the telescopic cylinder 18 into the sleeve 22 through the liquid inlet pipe 42, and the linkage piston 25 is moved toward the air hole 23 by water pressure, so that the linkage piston 25 can drive the piston column 533 to move in the same direction through the linkage rod 24, so that the nozzle body 532 can be retracted to the inside of the inner tube 52, and at the same time, when the telescopic piston 20 moves, the telescopic piston 20 will drive the telescopic rod 19 to move in the same direction, so that the telescopic rod 19 drives the pressurizing piston 16 to move toward the open end, and then the cleaning water tank 54 is filled with water through the water inlet 17. The internal cleaning water is sucked into the outer tube 51 for the next flushing, and while the pressurizing piston 16 moves toward the open end, the pressurizing piston 16 can spray the cleaning liquid in the cleaning chamber 28 into the inner tube 52 through a plurality of cleaning ports 30 arranged around it. At the same time, the nozzle body 532 and the connecting tube 531 inside the inner tube 52 are shrinking, and then when the nozzle body 532 and the connecting tube 531 shrink, the cleaning liquid sprayed through the cleaning port 30 flushes and cleans the nozzle body 532 and the connecting tube 531, and the cleaning liquid after cleaning flows out through the open end, and then the pressurizing piston 16 moves to contact the limit column 27, and the push rod 447 pushes the insertion rod 444 to close the extension channel, and then disinfectant is added for immersion disinfection.
