DETAILED DESCRIPTION

[0023] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0024] like Figure 1-Figure 4 As shown, this embodiment provides a medical endoscope cleaning machine, including a cleaning body 1, a flip opening and closing cover 2, a rotating nozzle 3 and an elastic deformation sleeve 4.

[0025] The cleaning body 1 has a cleaning tank 11, and the flip opening and closing cover 2 is used to cover and open the opening of the cleaning tank 11. A convex seat 12 is formed at the bottom of the cleaning tank 11, and a side leakage interface, an irrigation interface, an air intake interface and a liquid injection interface are arranged on the convex seat 12. The cleaning tank 11 has a drain port at the bottom.

[0026] A through hole is formed on the inward side of the flip opening and closing cover 2, and the rotating nozzle 3 is installed on the inward side of the flip opening and closing cover 2. The rotating nozzle 3 includes a rotating shaft 31 and a water outlet 32. A first water passage is formed in the middle of the rotating shaft 31, and two equally spaced retaining notches 311 are formed on the circumference of the rotating shaft 31. The retaining notches 311 include an extension section 3111, a lateral movement section 3112 and a limiting section 3113. The opening of the extension section 3111 is located at the end face of the rotating shaft 31 and extends inward. One end of the lateral movement section 3112 is connected to the extension section 3111, and the other end of the lateral movement section 3112 is connected to the limiting section 3113. The limiting section 3113 extends toward the end face of the rotating shaft 31, and a top ring 312 is formed on the upper end of the circumference of the rotating shaft 31.

[0027] The water outlet body 32 has an installation groove, and an insertion column 3211 is formed at the bottom of the installation groove. The insertion column 3211 has a second water passage, and the insertion column 3211 is adapted to the first water passage. A sealing ring 5 is arranged between the insertion column 3211 and the first water passage. Two equally spaced limit blocks 3212 are formed on the circumferential surface of the opening of the installation groove. The limit blocks 3212 are adapted to the locking notch 311. When installing, the limit blocks 3212 are aligned with the insertion section 3111 of the locking notch 311 and then inserted, and then rotated out. The water body 32 and the limit section 3113 move to the end of the lateral moving end, and then the water outlet 32 ​​is released. Under the action of its own weight, the water outlet 32 ​​moves downward, and the limit block 3212 is inserted into the limit section 3113 to achieve installation. Then, the water outlet 32 ​​and the rotating shaft 31 are arranged to achieve quick disassembly and assembly. During the rotation of the rotating shaft 31, since the water outlet 32 ​​is affected by torque and gravity, the water outlet 32 ​​will not fall out of the limit section 3113. The above arrangement can achieve quick disassembly and assembly of the water outlet 32.

[0028] The water outlet body 32 includes a water outlet body 321 and a water outlet sleeve 323. The water outlet body 321 includes a central column and three annular connecting columns 322 arranged at equal intervals. The connecting columns 322 are connected to the peripheral surface of the central column. The connecting column 322 has a first chamber. The first chamber has three rows of first water outlets 3221. The three rows of first water outlets are arranged on the peripheral surface of the third quadrant and the fourth quadrant of the vertical cross-sectional shape of the connecting column 322. The number of first water outlets 3221 is three rows, and the included angle of the vertical cross-section between adjacent first water outlets 3221 in each row is 30-45 degrees. The first chamber is connected to the second water passage of the central column. The water outlet sleeve 323 is sleeved on the connecting column 322. The starting end and the end of the connection between the water outlet sleeve 323 and the connecting column 322 are sleeved with a sealing ring 5. The water outlet sleeve 323 and the connecting column 322 are connected by interference fit. Preferably, the water outlet sleeve 323 and the connecting column 322 can also be connected by screws. The water outlet sleeve 323 has a second water outlet 3231, and the second water outlet 3231 corresponds to the first water outlet 3221. The connecting column 322 of the central column is formed with multiple rows of first water outlets 3221, and the water outlet sleeve 323 sleeved on the connecting column 322 has only one row of second water outlets 3231. By rotating the water outlet sleeve 323, the second water outlet opening corresponds to any row of first water outlets 3221, so that the water spraying direction of the water outlet sleeve 323 can be changed.

[0029] The elastic deformation sleeve 4 is sleeved on the rotating shaft 31 and is located between the lower surface of the abutting ring 312 and the upper surface of the water outlet 32. The elastic deformation sleeve 4 is a nylon sleeve or a rubber sleeve. The circumference of the elastic deformation sleeve 4 is formed with an oblique opening. The oblique opening is convenient for the elastic deformation sleeve 4 to be sleeved on the rotating shaft 31. The elastic deformation sleeve 4 is arranged below the abutting ring 312 of the rotating shaft 31. The elastic deformation sleeve 4 abuts against the elastic deformation sleeve 4 and the upper surface of the water outlet 32, so that the water outlet 32 ​​will not be dislodged during rotation due to the irregular placement of the endoscope in the cleaning tank 11 and then hitting the water outlet 32.
