DETAILED DESCRIPTION

[0018] See also Figure 1-Figure 11 , the present invention provides a technical solution: a perianal multifunctional fumigation instrument, comprising a toilet 1, comprising a fumigation box 2, the fumigation box 2 is independently arranged, and the fumigation box 2 is used to provide liquid medicine in the fumigation process; A spray mechanism, which is connected to the fumigation box 2 through an external pipe, and is used to spray the liquid medicine required during the fumigation process onto the affected part of the patient; The seat cushion 3 is placed on the toilet 1, and the spray mechanism is arranged on the inner circle of the seat cushion 3, so that the patient can sit on the seat cushion 3 for fumigation and washing; the toilet 1 is used to discharge the waste water generated during the fumigation and washing process.

[0019] When the fumigation device is in use, the fumigation box 2 and the cushion 3 are directly moved to the bathroom, where the cushion 3 is placed on the toilet 1, and then the patient sits directly on the toilet 1 for fumigation. During the fumigation process, the fumigation box 2 inputs the liquid medicine and steam used for fumigation into the spray mechanism through an external pipe, and then the patient is fumigated through the spray mechanism. During this process, the waste liquid generated by the fumigation directly enters the toilet 1 and is discharged into the sewer. At the same time, steam is generated during the fumigation process. Since the fumigation environment is located in the bathroom, the steam will not escape into other indoor environments, thereby preventing the steam from polluting the indoor environment during the fumigation process.

[0020] The present invention divides the fumigation device into two modules, namely a fumigation box 2 and a seat cushion 3, so that the fumigation process can be carried out on a common toilet 1 in life. This effectively allows patients to use the product without having to consider the discharge of waste liquid generated during use, thereby effectively reducing the user's use cost.

[0021] Furthermore, the fumigation box 2 includes a shell 2-1, and a first connector 2-7 and a second connector 2-8 are fixedly installed on the outer wall of the shell 2-1. The first connector 2-7 is connected to a spray mechanism through an external pipe and provides the spray mechanism with liquid medicine and clean water for cleaning. The second connector 2-8 is connected to a spray mechanism through an external pipe and provides the spray mechanism with liquid medicine steam and air flow for drying.

[0022] During the fumigation process, the spray mechanism first sprays medicinal liquid steam to the patient's affected area to fumigate the affected area. After the fumigation is completed, the affected area is sprayed with medicinal liquid for flushing, and then cleaned with clean water, and finally the affected area is dried by air flow.

[0023] Furthermore, the spray mechanism includes a triangular plate 4, which is fixedly connected to the right end of the inner wall of the cushion 3, the triangular plate 4 is inclined to the lower left, the end of the triangular plate 4 is upturned, and the upper end of the upturned part of the triangular plate 4 is penetrated and embedded with a mounting plate 5, and the mounting plate 5 is respectively penetrated and embedded with a jet head 6 and a liquid spray head 7, the jet head 6 is connected to the second connecting head 2-8, and the liquid spray head 7 is connected to the first connecting head 2-7, and a protective mechanism is arranged at the jet head 6, which is used to close the jet head 6 when the liquid spray head 7 sprays liquid.

[0024] Furthermore, an infrared lamp 8 connected to a power source is embedded in the center of the upper end of the triangle plate 4 .

[0025] During use, the infrared lamp 8 is started to continuously disinfect the fumigation environment.

[0026] Furthermore, the protection mechanism includes a protection shell 9, which is fixedly connected to the upper end of the mounting plate 5. The shape of the protection shell 9 is an arc concentric with the mounting plate 5. The nozzle 6 is located in the protection shell 9. The protection shell 9 is provided with a through groove 9-1 at the upper end of the nozzle head 6. The inner wall of the upper end of the protection shell 9 is slidably connected with a sealing plate 9-2 along the arc trajectory of the protection shell 9. The sealing plate 9-2 is used to close the through groove 9-1. The triangular plate 4 is provided with a control mechanism, and the control mechanism is used to control the sliding of the sealing plate 9-2.

[0027] During use, when the liquid spray head 7 sprays liquid, the interior of the toilet 1 is filled with water mist. In order to prevent the water mist from entering the spray head 6 and contaminating the spray head 6, causing the spray head 6 to be blocked, the control mechanism controls the sealing plate 9-2 to slide and close the through groove 9-1, so that the spray head 6 is isolated from the outside world through the protective shell 9; correspondingly, when the liquid spray head 7 stops spraying liquid and the spray head 6 starts spraying, the control mechanism controls the sealing plate 9-2 to slide and open the through groove 9-1, so that the spray head 6 is exposed for spraying.

[0028] Furthermore, the control mechanism includes a first connector 10, which is fixedly connected to the lower end of the triangle plate 4, and a second connector 11 is fixedly connected to the lower end of the nozzle 6. The second connector 11 is rotatably connected to a connecting ring 13, and the connecting ring 13 is fixedly connected to a hose 12. The hose 12 passes through the first connector 10 and is fixedly connected to the first connector 10. The hose 12 is connected to the second connector 2-8 through an external pipeline, and a protective tube 14 is connected to the outer shell of the hose 12; one end of the protective tube 14 is fixedly connected to the end of the first connector 10, and the other end of the protective tube 14 is arranged at the lower end of the connecting ring 13; the part of the hose 12 in the protective tube 14 is twisted around the axis of the hose 12 for multiple turns, and the connecting ring 13 is externally connected to an elastic mechanism, which applies torque to the connecting ring 13, and the elastic mechanism is used to keep the hose 12 in a twisted state; the outer wall of the connecting ring 13 is fixedly connected to a hairspring box 15, and the output end of the hairspring box 15 is transmission-connected to a driving mechanism, and the driving mechanism is used to control the sliding of the sealing plate 9-2.

[0029] During the jetting process of the jet head 6, the airflow is introduced into the jet head 6 through the hose 12 and then ejected. During this process, since the hose 12 is in a twisted state in the initial state, the inner wall of the hose 12 is closed. Then, when the airflow is introduced into the hose 12, the closed inner wall of the hose 12 will be propped up by the air pressure, which further causes the twisted hose 12 to overcome the elastic force of the elastic mechanism under the action of the air pressure, rotate and restore to a straight state. Furthermore, the hose 12 drives the connecting ring 13 to rotate. Further, the connecting ring 13 drives the hairspring box 15 and the output end of the hairspring box 15 to rotate, so that the output end of the hairspring box 15 provides driving force for the driving mechanism through the elasticity of the hairspring box 15.

[0030] The twisted hose 12 of the present invention will rotate after the airflow is introduced, and the rotation provides power for the sliding of the sealing plate 9-2, so that the linkage between the introduced airflow and the sliding of the sealing plate 9-2 is closer, so that when the nozzle 6 sprays, the opening action of the sealing plate 9-2 is more sensitive and stable.

[0031] Furthermore, the driving mechanism includes an arc groove 16 that penetrates and is opened on the mounting disk 5. The arc groove 16 is concentric with the mounting disk 5 and is located in the protective shell 9. A first rotating shaft 17 is rotatably connected to the axis center of the lower end of the mounting disk 5. A connecting rod 18 is fixedly connected to the side wall of the first rotating shaft 17. The connecting rod 18 is fixedly connected to a sliding rod 19. The upper end of the sliding rod 19 is fixedly connected to the lower end of the sealing plate 9-2. A first gear 20 is rotatably connected to the outer wall of the hairspring box 15. The inner wall of the first gear 20 is fixedly connected to the output end of the hairspring box 15. A second rotating shaft 21 is rotatably connected to the lower end of the mounting disk 5. A second gear 22 is fixedly connected to the lower end of the second rotating shaft 21. The second gear 22 meshes with the first gear 20. A third gear 23 is fixedly connected to the side wall of the second rotating shaft 21 at the upper end of the second gear 22. A fourth gear 24 is fixedly connected to the lower end of the first rotating shaft 17. The third gear 23 meshes with the fourth gear 24. The number of teeth of the third gear 23 is less than that of the second gear 22.

[0032] When the jet head 6 starts to spray, the air flow passes through the hose 12, causing the hose 12 to rotate, and the hairspring box 15 rotates, and then the output end of the hairspring box 15 applies a pulling force to the first gear 20 that makes the first gear 20 have a rotation tendency, and as the relative rotation amplitude of the hairspring box 15 and the first gear 20 increases, the output end of the hairspring box 15 pulls out more hairspring from the hairspring box 15 along with the first gear 20. The structure of the hairspring box 15 is similar to a tape measure, and the greater the pulling force, the longer the pulling force pulls the first gear 20 to rotate with the hairspring box 15. When the first gear 20 rotates, the fourth gear 24 is driven to rotate through the second gear 22 and the third gear 23, wherein the second gear 22 and the third gear 23 are used to increase the transmission ratio from the first gear 20 to the fourth gear 24, so that the pulling force provided by the hairspring box 15 required for the fourth gear 24 to rotate is reduced, and then the fourth gear 24 rotates to drive the first shaft 17 to rotate, so that the first shaft 17 drives the sealing plate 9-2 to slide through the connecting rod 18 and the sliding rod 19, so that the sealing plate 9-2 is opened, thereby exposing the jet head 6. As the sealing plate 9-2 is opened, the slide bar 19 moves to the extreme position of the arc groove 16 and cannot move further. Correspondingly, the first gear 20 cannot continue to rotate. During the continued rotation of the hairspring box 15, it rotates relative to the first gear 20. When the jet head 6 finishes jetting, the airflow no longer enters the hose 12, and the air pressure in the hose 12 drops. Under the elastic force of the elastic mechanism, the hose 12 is twisted and reset. Correspondingly, the connecting ring 13 rotates in the opposite direction to reset, and the hairspring box 15 rotates in the opposite direction. During this process, the hairspring box 15 rotates in the opposite direction relative to the first gear 20, so that the pulling force applied by the output end of the hairspring box 15 to the first gear 20 is gradually reduced, until the elastic force accumulated in the hairspring box 15 is completely released, the corresponding output end of the hairspring box 15 is reset, and the output end of the hairspring box 15 moves to the extreme position, so that the hairspring box 15 drives the first gear 20 to rotate in the opposite direction to reset, so that the first gear 20 drives the sealing plate 9-2 to slide in the opposite direction to close the through groove 9-1 through various transmission parts.

[0033] The present invention utilizes an elastic member to transfer the driving force of the hose 12 to rotate, thereby driving the sealing plate 9-2 to slide, so that the elastic member can store the excess kinetic energy released during the rotation of the hose 12 by accumulating elastic potential energy, thereby making the sliding and resetting of the sealing plate 9-2 more stable.

[0034] Furthermore, a fixing bar 28 is fixedly connected to the inner wall of the seat cushion 3, and the lower end of the fixing bar 28 is rotatably connected to the upper end of the triangular plate 4. A track ring 25 is provided at the lower end of the connecting ring 13, and the track ring 25 is provided with a downwardly extending slide rail 26. The slide rail 26 is slidably connected to a slip ring 27, and the slip ring 27 is fixedly connected to the end of the protective tube 14.

[0035] When the jet head 6 starts to spray and the hose 12 rotates to become straight, the total length of the corresponding hose 12 will become longer, and then the total length of the hose 12 will be greater than the length of the protective tube 14, so that the hose 12 extends out of the protective tube 14 and then the hose 12 lifts the lower end of the triangular plate 4, so that the triangular plate 4 rotates upward around the fixing strip 28, and further makes the spraying directions of the jet head 6 and the liquid spray head 7 approach the vertical direction. Further summary shows that when the liquid spray head 7 sprays liquid, the spraying direction of the liquid spray head 7 is relatively inclined, and when the jet head 6 sprays gas, the spraying direction of the jet head 6 is relatively vertical; correspondingly, when the liquid spray head 7 sprays liquid, in order to prevent the liquid from falling back and contaminating the nozzle, the direction of the liquid spray head 7 spraying the liquid should be inclined, and when the jet head 6 sprays gas, in order to make the gas utilization rate higher, the direction of the gas spraying of the jet head 6 should be as vertical as possible. It can be known from life experience that when a person sits on the toilet, the fit between the buttocks and the seat cushion 3 is higher than the fit between the legs and the seat cushion 3.

[0036] Furthermore, a medicine box 2-2 is provided in the shell 2-1, and the medicine box 2-2 is used to place medicine packages. A warm water tank 2-3 is provided in the shell 2-1. Both the medicine box 2-2 and the warm water tank 2-3 have a heating function. Both the medicine box 2-2 and the warm water tank 2-3 are externally connected to water injection pipes for injecting clean water. The first connector 2-7 and the second connector 2-8 are connected to a conversion valve 2-9 at one end in the shell 2-1. The medicine box 2-2 and the warm water tank 2-3 are both connected to a first liquid guide tube 2-10. The first liquid guide tube 2-10 is connected to the conversion valve 2-9 on the first connector 2-7. Water pumps for injecting liquid into the first liquid guide tube 2-10 are provided in the medicine box 2-2 and the warm water tank 2-3.

[0037] Furthermore, an air pump 2-4 is provided in the shell 2-1, and the air pump 2-4 is used to provide temperature-adjustable airflow. The air pump 2-4 is connected to the first air duct 2-5 and the second air duct 2-6. The first air duct 2-5 is connected to the conversion valve 2-9 on the second connector 2-8, and the second air duct 2-6 is connected to the medicine box 2-2. A third air duct 2-12 that only allows steam to enter is provided at the upper end of the medicine box 2-2. The third air duct 2-12 is connected to the conversion valve 2-9 on the second connector 2-8.

[0038] When in use, first put the medicine bag into the medicine box 2-2, and heat the medicine box 2-2 at the same time, so that the medicine liquid in the medicine box 2-2 boils and produces steam, and then the steam enters the spray mechanism through the third air duct 2-12 for use, and then cold water is passed into the medicine box 2-2 to reduce the temperature of the medicine liquid in the medicine box 2-2, and then the medicine liquid with reduced temperature is introduced into the spray mechanism to rinse the patient, and then the warm water in the warm water tank 2-3 is introduced into the spray mechanism to rinse the patient to remove the medicine liquid on the patient, and finally, the clean air flow is sprayed to the patient for drying.
