[0023] An inner column 5, wherein the inner column 5 is arranged inside the cleaning rod 4, and a disinfectant storage bag 52 is arranged inside the inner column 5. The disinfectant inside the disinfectant storage bag 52 is squeezed into the inner cavity of the endoscope by squeezing the disinfectant storage bag 52, and the inner cavity of the endoscope is cleaned in coordination with the rotation of the cleaning rod 4; The disinfectant storage bag 52 structure in the inner column 5 stores disinfectant for disinfecting the inner cavity of the endoscope. During use, the disinfectant is squeezed out of the disinfectant storage bag 52 and flows into the inner cavity of the endoscope. In combination with the structure of the brush layer 41, the inner cavity of the endoscope is deeply cleaned.

[0024] A cleaning component 7 is installed on the cleaning rod 4. An airbag 73 is installed on the side of the cleaning component 7 away from the cleaning rod 4. After the airbag 73 is inflated, it slides horizontally in the inner cavity of the endoscope and cleans the disinfectant remaining on the surface of the inner cavity of the endoscope to keep the inner cavity of the endoscope dry.

[0025] The structure of the cleaning component 7 is such that when the entire device is taken out from the inner cavity of the endoscope, the airbag 73 expands and contacts the inner wall of the endoscope, absorbing the residual moisture on the inner wall to keep the inner cavity of the endoscope dry.

[0026] The connecting ring 11 is fixed on the outer wall near the end of the blowing pipe 1, and a card slot 12 is arranged on the outer wall of the connecting ring 11. There are a plurality of card slots 12, and the card slots 12 are distributed circumferentially on the connecting ring 11. The card slot 12 is arranged in an L shape. A card block 31 is arranged on the inner wall of the connecting sleeve 3, and the card block 31 is engaged with the card slot 12. The card block 31 is arranged in an L shape. The number of the card blocks 31 corresponds to the number of the card slots 12, and the card blocks 31 correspond to the distribution of the card slots 12.

[0027] Insert the block 31 horizontally along the slot 12 so that the connecting sleeve 3 is sleeved on the connecting ring 11, rotate the connecting sleeve 3 relative to the connecting ring 11 so that the block 31 rotates in the slot 12, and engage the end of the block 31 with the slot 12 so that the connecting sleeve 3 is installed on the connecting ring 11.

[0028] The inflection point of the card block 31 is set to an arc shape, and a movable groove 13 is set on the side of the card slot 12. A stop block 2 is horizontally slidably connected in the movable groove 13, and the stop block 2 is set to a trapezoid. The side of the stop block 2 facing the opening of the card slot 12 is set to a hypotenuse, and the hypotenuse of the stop block 2 abuts against the inflection point of the card block 31, and the right-angled side of the stop block 2 facing the side of the card slot 12 abuts against the side wall of the card block 31. A first spring 21 is set between the stop block 2 and the inner wall of the movable groove 13, one end of the first spring 21 is fixedly connected to the inner wall of the stop block 2, and the other end of the first spring 21 is fixedly connected to the inner wall of the movable groove 13, and telescopic rods 22 are respectively set on both sides of the first spring 21, and the movable end and fixed end of the telescopic rod 22 are respectively fixedly connected to the stop block 2 and the inner wall of the movable groove 13.

[0029] The inflection point of the block 31 is an arc, and the outer wall of the block 2 is a bevel. In the process of inserting the block 31 into the slot 12, the arc of the block 31 abuts against the bevel of the block 2, and pushes the block 2 to shrink into the movable slot 13. After the block 31 is fully inserted into the slot 12, the elastic force of the first spring 21 pushes the block 2 to pop out outward and pushes the block 31 to rotate, so that the block 31 abuts against the slot 12. The first spring 21 always gives the block 2 an outward force, so that the block 2 abuts against the outer wall of the block 31, avoiding the block 31 from rotating in the opposite direction during use, causing the connecting sleeve 3 to fall off. The structure of the telescopic rod 22 limits the distance that the block 2 slides outward to prevent the block 2 from falling off from the movable slot 13.

[0030] The connecting sleeve 3 is fixedly connected to a fixing seat 32 on one side away from the blowing pipe 1, and the cleaning rod 4 is installed in the fixing seat 32.

The cleaning rod 4 is rotatably connected to the connecting sleeve 3 through the ball block 44.

[0031] The cleaning rod 4 is fixed in the fixing seat 32 by the structure of the fixing seat 32, and because the ball block 44 is rotatably connected to the rotating groove, after the cleaning rod 4 is installed on the connecting sleeve 3, the two can rotate relative to each other, but the cleaning rod 4 and the connecting sleeve 3 will not separate.

[0032] A guide plate 33 is installed in the middle of the connecting sleeve 3, and a guide groove 34 connected on both sides is provided on the guide plate 33. The guide groove 34 is inclined on the guide plate 33. The inner wall of the cleaning rod 4 on one side facing the connecting sleeve 3 is provided with a blade 43. The blade 43 is inclined and distributed circumferentially in the connecting sleeve 3. The gas blown out of the blowing pipe 1 is obliquely introduced into the cleaning rod 4 through the guide groove 34, and blows the blade 43 to rotate, thereby driving the cleaning rod 4 to rotate on the connecting sleeve 3.

[0033] The gas blown out of the air blowing pipe 1 is guided by the structure of the guide groove 34, so that after the gas enters the cleaning rod 4, the airflow enters at an angle and pushes the blade 43 to rotate, thereby causing the blade 43 to rotate relative to the guide plate 33, driving the cleaning rod 4 to rotate on the connecting sleeve 3.

[0034] The inner column 5 is configured to be a truncated cone, and one end of the inner column 5 toward the connecting sleeve 3 is in a diffusion shape.

The number of the openings 42 is staggered with the number of the brush layer 41, and the gas blown into the air tube 1 enters the inner cavity of the endoscope from the openings 42.

[0035] The airflow blown into the cleaning rod 4 through the air blowing tube 1 diffuses outward after contacting the end of the inner column 5, so that the airflow can blow air to the inner cavity of the endoscope along the opening 42. After the brush layer 41 scrapes off the stains remaining in the inner cavity of the endoscope, the airflow in the opening 42 blows away the impurities. Together, the stubborn impurities in the inner cavity of the endoscope are cleaned. At the same time, the drying rate of the inner cavity of the endoscope is accelerated by blowing.

[0036] A plurality of fixing columns 57 are fixedly connected to the side wall of the inner column 5, and the inner column 5 is fixed to the middle part of the cleaning rod 4 by the plurality of fixing columns 57. A mounting column 51 is installed in the inner column 5, and a disinfectant storage bag 52 is installed in the mounting column 51. A first push plate 8 is slidably connected to the inner side of the inner column 5, and the first push plate 8 is squeezed and connected to the disinfectant storage bag 52.

[0037] The inner column 5 is fixed in the cleaning rod 4 by the fixing column 57, and the disinfectant storage bag 52 is installed in the inner column 5 by the mounting column 51. When the air blowing tube 1 is blowing, the airflow in the air blowing tube 1 drives the second push plate 82 to slide horizontally in the direction of the cleaning rod 4. Under the connecting action of the connecting rod 81, the first push plate 8 is pushed to move in the same direction as the second push plate 82, and the first push plate 8 squeezes the disinfectant storage bag 52, so that the disinfectant in the disinfectant storage bag 52 is squeezed into the inner cavity of the endoscope, so as to disinfect during the cleaning of the inner cavity of the endoscope.

[0038] A plurality of outlet pipes 53 are installed on the side wall of the inner column 5. The inner side of the outlet pipe 53 extends into the disinfectant storage bag 52. The outlet pipe 53 is sealed and connected to the disinfectant storage bag 52. The outer side of the outlet pipe 53 extends to the opening 42 of the cleaning rod 4. A fixing ring 55 is fixedly connected to the inner wall of the outer side of the outlet pipe 53. A discharge pipe 6 is slidably connected in the fixing ring 55. The discharge pipe 6 is a cavity structure with an opening arranged toward one side of the disinfectant storage bag 52. The inner outer wall of the discharge pipe 6 is fixedly connected to the inner wall of the outlet pipe 6. A connecting plate 62 is connected, and a sealing slide is formed between the connecting plate 62 and the inner wall of the outlet pipe 53 and between the outlet pipe 6 and the fixing ring 55. A plurality of outlet grooves 61 are provided on the outer wall of the outlet pipe 6.

[0039] During the process of the disinfectant being squeezed out, the disinfectant moves outward along the outlet pipe 53, pushing the discharge pipe 6 to slide outward until the discharge groove 61 on the discharge pipe 6 moves to the outside of the sealing gasket 56, so that the disinfectant enters the inner cavity of the endoscope. In the initial state, when the internal disinfectant pressure is not strong enough to push the discharge pipe 6 outward, the connecting plate 62 slides toward the inside of the fixing ring 55 under the elastic force of the second spring 63, so that the discharge groove 61 remains in the sealing gasket 56, preventing the discharge groove 61 from discharging the disinfectant when not in use.

[0040] A cleaning assembly 7 is provided at the end of the cleaning rod 4. A connecting column 71 is fixedly connected to the side of the cleaning assembly 7 facing the cleaning rod 4.

[0042] When the air blowing tube 1 blows air into the cleaning rod 4, part of the gas enters the cleaning assembly 7 along the air guide tube 54, so that the air pressure inside the airbag 73 increases, thereby expanding the airbag 73, and the airbag 73 presses against the inner wall of the endoscope. The airbag 73 in this state is pulled outward to remove the residual moisture and impurities in the inner cavity of the endoscope, thereby ensuring efficient cleaning, disinfection and drying of the endoscope.
