[0015] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0016] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0017] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] Please see Figures 1 to 6 The image shows a surgical instrument cleaning machine according to the first embodiment of the present invention, including a body 10, a cleaning tank on the body 10, a cover plate 20 for covering the cleaning tank on the body 10, a drying mechanism 30 on the cover plate 20, the drying mechanism 30 including an air gun disposed through the cover plate 20, a solenoid valve 354 disposed on the air gun, a connecting structure connecting the air gun and the cover plate 20, and a driving component for driving the air gun to rotate circumferentially. The surgical instrument cleaning machine also includes an air box for supplying air to the air gun and a controller, the controller being electrically connected to the solenoid valve 354 and the driving component.

[0020] Understandably, this invention, by setting a drying mechanism 30 on the cover plate 20, allows the controller to activate the solenoid valve 354 and drive assembly after the internal cleaning and drying of the gastrointestinal endoscope tube, as well as the external cleaning of the tube, is completed. The solenoid valve 354 controls the air gun to release drying gas from the air chamber. During gas release, the drive assembly also controls the air gun to rotate circumferentially, allowing it to dry the tube's surface. Multiple air guns can be used, all rotating circumferentially to cover the entire cleaning tank as much as possible, improving drying efficiency. After drying, the controller closes the drive assembly and solenoid valve 354, the cover plate 20 is opened, and the tube is removed using sterile gloves. It should be noted that the pneumatic device on the air gun is not shown in the figure. This pneumatic device is connected to the solenoid valve 354 and is used to extract high-pressure gas from the air chamber; this is a technique known to those skilled in the art. It should also be noted that although only four drying mechanisms 30 are shown in the figure, more can be added as needed to increase the drying coverage.

[0021] This invention sets up a drying mechanism 30 on an existing machine, and the drying operation outside the pipe can be realized through a simple PLC controller.

[0022] The air box is located outside the machine body 10 and is relatively large, so it is not shown in the figure. Each drying mechanism 30 is connected to the air box.

[0023] Specifically, in this embodiment, the connecting structure includes a first mounting block 34 that penetrates the cover plate 20, and the first mounting block 34 has a receiving hole through it; the air gun includes a gun head 351, a first universal ball 352, and a gun body 353 connected in sequence, the first universal ball 352 is rotatably disposed in the receiving hole, and the gun head 351 is located on the side of the cover plate 20 facing the cleaning tank.

[0024] Understandably, the cover plate 20 can be made of plexiglass. Holes are made in the plexiglass and mounting blocks are fixedly installed. Then, the first universal ball 352 of the air gun is rotated and installed in the receiving hole, so that the air gun can rotate around the first universal ball 352, thereby adjusting the position of the gun head 351.

[0025] Furthermore, the drive assembly includes a rotating plate 37, a second mounting block 36 located at a non-axial position of the rotating plate 37, a second universal ball 355 located at the end of the gun body 353, a rotating shaft located at the axial position of the rotating plate 37, and a servo motor 38 connected to the rotating shaft. The second universal ball 355 is rotatably disposed in the second mounting block 36. The drying mechanism 30 is covered with a fixed shell 31, which is fixedly connected to the cover plate 20. The servo motor 38 is fixedly connected inside the fixed shell 31, and the rotating plate 37 is rotatably connected to the inner wall of the fixed shell 31.

[0026] Understandably, when it is necessary to control the circumferential rotation of the air gun, the servo motor 38 drives the rotating shaft and the rotating plate 37 to rotate. The rotating plate 37 drives the second mounting block 36 at the non-axial position to rotate, which in turn drives the second universal ball 355 to rotate around the center of the first universal ball 352, so as to drive the gun head 351 to rotate circumferentially. The fixed shell 31 can be detachably connected to the cover plate 20 by bolts. The main function of the fixed shell 31 is to protect the drying mechanism 30, and at the same time to support the servo motor 38 and the rotating plate 37.

[0027] Furthermore, a vent pipe 32 is provided between the air gun and the air box. The vent pipe 32 is made of elastic material and is spring-shaped. The vent pipe 32 is connected to the gun body 353. A flow channel for gas to pass through is provided in the gun body 353, the first universal ball 352 and the gun head 351. The flow channel is connected to the inner channel of the vent pipe 32.

[0028] Understandably, the vent pipe 32 serves both as a gas flow conduit and as a degree of flexibility. In this embodiment, a servo motor 38 drives the rotating plate 37 to rotate reciprocally, thereby driving the nozzle 351 to rotate back and forth. When the air gun rotates reciprocally, the vent pipe 32 can follow the air gun with limited displacement. When the solenoid valve 354 controls the pneumatic device to pressurize and draw air from the air box, the high-pressure gas will pass through the vent pipe 32 and the flow channel in sequence, and then be ejected from the nozzle. An opening needs to be made on the fixed housing 31 for the vent pipe 32 to pass through, providing space for the vent pipe 32 to move when the rotating plate 37 drives the air gun to rotate reciprocally.

[0029] It should be noted that the internal structure of the air gun in this application is the same as that of a conventional air gun, only the appearance is changed. In order to facilitate the circumferential rotation of the air gun, a gas compression device is provided in the air box.

[0030] Furthermore, the cover plate 20 is provided with an electromagnetic lock 40, which is electrically connected to the controller.

[0031] Understandably, when the cover plate 20 is closed, the machine body 10 is connected to the cover plate 20 by the electromagnetic lock 40. The electromagnetic lock 40 will be linked with the controller to indicate that the cover plate 20 is closed and the gastrointestinal endoscope tube cleaning can be performed. If the electromagnetic lock 40 does not contact the sensing block, the drying mechanism 30 cannot be started.

[0032] Preferably, the cover plate 20 is provided with a snap-fit ​​post 21, and the machine body is provided with a clamp 22 that snaps into the snap-fit ​​post 21.

[0033] Understandably, since the drying mechanism 30 has been added to the cover plate 20, the cover plate 20 has a certain weight. In order to maintain safety when opening and closing the cover plate 20, a snap-fit ​​post 21 and a clamp 22 have been added. When the cover plate 20 is opened, the clamp 22 clamps the snap-fit ​​post 21 to temporarily fix the cover plate 20. The clamp 22 can be made of a material with a certain degree of elasticity.

[0034] Furthermore, the cleaning tank is provided with a boss 12, and a through hole 13 is provided through the boss 12. The boss 12 is provided with a receiving cavity for accommodating cleaning liquid, clean water and gas. The cleaning tank is also provided with a water outlet structure 11 and a drainage structure 14.

[0035] Understandably, these structures are existing features of the cleaning machine. The workflow is as follows: various pipes are inserted into the through hole 13, and then the pressurizing device inside the boss 12 sequentially sends cleaning fluid, clean water, and gas into the pipes for cleaning and drying. Then, the waste liquid is discharged through the drainage structure 14. When it is necessary to clean the outer surface of the pipe, clean water and cleaning fluid are released through the water outlet structure 11, and the outer surface of the pipe is cleaned by ultrasonic waves. Some details of these existing structures will not be elaborated here.

[0036] In summary, the surgical instrument cleaning machine in the above embodiments of this utility model is equipped with a drying mechanism on an existing machine, and the drying operation on the outside of the pipe can be realized through a simple PLC controller. In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
