The cleaning head 405 is connected to the three-pronged branch pipe 410 through a guide pipe 406. The guide pipe 406 is provided with a water pump 407 for controlling the flow rate. The guide pipe 406 is movably passed through the side wall of the movable disk 403 and is fixedly connected with the three-pronged branch pipe 410, so that the guide pipe 406 can rotate slightly with the cleaning head 405 without twisting and damage, so as to achieve continuous water supply.

[0039] The surface of the cleaning head 405 is provided with a through hole for contacting water, and the bottom of the outer cover 401 is also fixedly connected to a waste pipe 409 for discharging waste.

[0040] The intelligent processing technology process of accelerating the peristalsis and cleaning of the intestinal stoma of the present invention is as follows:

[0041] S1. The peristaltic frequency of the intestine attached to the inner wall of the skin-friendly layer 3074 is monitored by the peristaltic sensor provided in the skin-friendly layer 3074. If the peristaltic frequency of the intestine exceeds the preset threshold frequency, it is determined that the intestine is in the waste discharge stage at this time, and the start of this stage is determined by outputting a first determination signal to the controller 305. On the contrary, if the peristaltic frequency of the intestine does not exceed the preset threshold frequency, it is determined that the intestine is in the dormant stage at this time, and a second determination signal is output to the controller 305 to determine the start of this stage.

[0042] S2, the controller 305 receives the first determination signal and outputs the driving control of the electric push rod 304, controls the movable end of the electric push rod 304 to drive the outer cover body 401 connected to it through the fixed block to extend and move toward the outer end and move away from the human body, so that the entire component cleaning mechanism 4 gradually separates from the outer end of the external fixed tube 301, and at the same time, the telescopic rod 306 is stretched in the process of the component cleaning mechanism 4 moving outward to ensure that the telescopic rod 306 is always stably connected between the massage component 307 and the movable disk 403, so as to ensure the normal operation of the cleaning mechanism 4 and related components. At the same time, after the cleaning mechanism 4 separates from the external fixed tube 301, the outer end of the external fixed tube 301 is exposed, so that the intestinal stoma fixed at the end of the external fixed tube 301 is exposed, so that the intestine is convenient for the intestinal stoma to discharge waste outward through the exposed intestinal stoma;

[0043] S3, the controller 305 receives the first determination signal and outputs the driving control of the servo motor 3031, controls the output shaft of the servo motor 3031 to drive the driving gear 3032 connected thereto to rotate back and forth in both directions, so that the clamping assembly 302 drives the driven gear 3072 meshing with the bottom thereof to obtain the driving force, and causes the massage assembly 307 to rotate back and forth in both directions along the interlayer between the external fixing tube 301 and the intestine, so as to gently massage the surface of the intestine back and forth through the skin-friendly layer 3074, accelerate the peristalsis of the intestine, and relieve the local pressure of the intestine;

[0044] S4, after the waste discharge is completed, the intestinal peristalsis frequency detected by the peristalsis sensor is lower than the preset threshold frequency, at this time, the controller 305 receives the second determination signal and outputs the driving control of the electric push rod 304, controls the movable end of the electric push rod 304 to drive the cleaning mechanism 4 to shrink to the outer end of the external fixed tube 301, so that the cleaning mechanism 4 seals the intestinal stoma fixed by the outer end of the external fixed tube 301 again, and the guide tube 406 in the cleaning mechanism 4 touches the surface of the intestinal stoma;

[0045] S5. After the controller 305 receives the second determination signal, it continues to control the servo motor 3031 to drive within a preset period of time. Along with the reciprocating circular rotation of the massage component 307, the massage component 307 drives the movable disk 403 connected thereto and the connecting rod 404, the cleaning head 405, the guide tube 406, and the water pump 407 installed on the movable disk 403 to make a circular rotation along the inner cavity of the outer cover 401 through the telescopic rod 306. The range of the reciprocating circular rotation is controlled within the arc inner wall of the arc guide groove 3022. At the same time, the controller 305 05 receives the second determination signal and also outputs the driving control of the water pump 407 within a preset time period, controls the water pump 407 to extract water into the inner cavity of the water tank 402 through the three-pronged branch pipe 410 connected thereto, and the extracted water flows into the inner cavity of the cleaning head 405 through the water pump 407 and the guide pipe 406, and finally sprays on the surface of the stoma from the inner cavity of the cleaning head 405 to automatically clean the stoma. After the cleaning time is over, the servo motor 3031 stops driving, the massage component 307 and the cleaning head 405 stop rotating, the water pump 407 stops supplying water, and finally the waste water from the stoma cleaning is discharged from the waste pipe 409.

[0046] S6, executing the cyclic control process of S1-S5, accelerating the intestinal peristalsis at the end of the stoma, speeding up the waste discharge efficiency, and automatically cleaning the stoma after the waste discharge is completed, which is an automatic integrated operation process.

[0047] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or modifications within the technical scope disclosed by the present invention; according to the technical plan and its improved conception of the present invention, all of which should be included under the protection of the present invention.
