[0026] This application is aimed at the cleaning brush structure and usage method in the patent, which is not convenient for cleaning the reciprocating threading in the lumen of the flexible endoscope, and the cleaning effect is poor. In addition, manual reciprocating cleaning is easy to cause fatigue, and the efficiency of use needs to be improved. This application adopts a reciprocating threading mechanism and an automatic cleaning drive mechanism. The automatic cleaning drive mechanism is assembled on the wire reel, which is convenient for the linked wire reel to be taken out of the shell together, which is convenient for maintenance.

[0027] In order to realize a reciprocating threading cleaning structure, the innovation of the present application lies in: it also includes a reciprocating threading mechanism and an automatic cleaning drive mechanism; the reciprocating threading mechanism drives the shaft through the automatic cleaning drive mechanism coupling drive shaft, so that the wire reel enables the stainless steel threading wire to be wound on the wire reel or pass through the shell opening to connect to the cleaning brush for use, thereby achieving the effect of the stainless steel threading wire allowing the cleaning brush to reciprocately clean the flexible endoscope.

[0028] The reciprocating threading mechanism in this application is described as follows:

[0029] The reciprocating wire threading mechanism 2 includes a protective shell 21, a wire reel 25, and a stainless steel wire threading wire 5. The top surface of the outer shell is open and provided with a cover groove 211, and a top cover 212 is movably installed in the cover groove 211. One end of the cover groove 211 is sealed. Manually moving the top cover 212 along the track of the cover groove 211 facilitates removing the top cover 212, thereby taking out the wire reel 25 and the automatic cleaning mechanism. There is a shell opening 22 on one side of the outer shell through which the other end of the stainless steel wire threading wire 5 passes. A retaining ring 26 is provided along the outer circumference of the wire reel 25. The retaining ring 26 is arranged along the front and rear edges of the outer circumference of the wire reel 25 and is used to wind and limit the stainless steel wire threading wire 5. One end of the stainless steel wire threading wire 5 is wound and installed inside the wire reel 25. One end of the stainless steel wire threading wire 5 passes out of the protective shell 21 and is connected to the cleaning brush 1. A shaft body 29 is fixedly installed at the center of the wire reel 25. A silica gel tube is sleeved outside the stainless steel wire threading wire 5. An externally threaded connecting column 51 with an integral structure is provided at one end of the stainless steel wire threading wire 5. A wire column 27 is provided on the wire reel 25, and a wire hole 28 is opened in the wire column 27. One end of the stainless steel wire threading wire 5 passes through the wire hole 28 and is installed and fixed. An internally threaded connecting tube 52 for screwing the externally threaded connecting column 51 is provided at the rear end of the cleaning brush 1, and it is screwed and fixed. An internally threaded hole 30 is embedded at the front end of the shaft body 29, and a screwing component 4 is screwed on the internally threaded hole 30. The screwing component 4 includes a screw post 41 and a fixing plate 42 provided at the outer end of the screw post 41. It is convenient to unscrew the screwing component 4 and take out the wire reel 25 from the outer shell. A coupling column 31 is provided at the rear end of the shaft body 29, and it is connected to the drive shaft of the drive motor 62 through a coupling. It is convenient for the drive motor 62 to drive the wire reel 25 to rotate.

[0030] Further, in the present application, the automatic brushing drive mechanism is installed at one end of the reciprocating wire threading mechanism 2; for the specific structure of the automatic brushing drive mechanism, please refer to the attached drawings of the specification and the following description:

[0031] The automatic cleaning drive mechanism 6 includes a waterproof shell 61, a drive motor 62 installed in the waterproof shell 61 and having a drive shaft, and a lithium battery 63. The model of the drive motor can be flexibly used, which is not the innovation point of the present application here. A knob 64 with a switch and forward and reverse functions is provided on the back of the waterproof shell 61, which is electrically connected to the drive motor 61 and the lithium battery 63. A charging hole 65 is also provided on the back of the waterproof shell 61, which is electrically connected to the lithium battery 63 and one end of the coupling shaft of the drive motor 61. Since there is a socket 23 on the back of the outer shell, the socket 23 is communicated with the cover groove 211 on one side and the top is open. A card frame 24 is provided below the socket 23, and the automatic cleaning drive mechanism 6 is placed in the card frame 24.

[0032] For the above electrical connection working principle, by operating the knob, the drive motor is powered on to work. As known in the existing art, when the knob rotates clockwise, it is turned on and rotates forward, and vice versa for reverse rotation and turning off. The charging port provides electrical energy for the lithium battery to make the drive motor work, thereby driving the wire reel connected by the coupling to rotate.

[0033] Working principle: During the use of this application, the stainless-steel wire threading wire connected to the wire reel in the reciprocating wire threading mechanism is screwed and fixed by the external thread connecting column connected to one end of it and the internal thread connecting pipe arranged at the rear end of the cleaning brush. The driving motor installed in the waterproof housing in the automatic cleaning driving mechanism is connected to the shaft body fixed on the wire reel through a coupling drive shaft. When the operation knob is powered on, the driving motor drives the shaft body to rotate, thereby driving the wire reel to rotate forward or backward. The stainless-steel wire threading wire installed on the wire reel can pass through the shell opening, enabling the screwed cleaning brush to reciprocate through the wire in the lumen of the flexible endoscope for cleaning.

[0034] During maintenance, open the top cover 212 along the cover groove 211, unscrew the screwing component 4 screwed to the front end of the shaft body 29, and take out the automatic cleaning driving mechanism 6 together with the wire reel 25 from the socket 23, which is convenient for maintenance. After the maintenance is completed, insert the automatic cleaning driving mechanism 6 together with the wire reel 25 into the socket 23 again, place the automatic cleaning driving mechanism 6 on the card frame 24, and screw the screwing component 4 to the front end of the shaft body 29.

[0035] Working principle of the cleaning brush for the flexible endoscope: Since the metal soft rod plays a role in supporting and pulling the entire cleaning brush, when using the cleaning brush, the automatic cleaning driving mechanism drives the reciprocating wire threading mechanism to push the cleaning brush screwed with the stainless-steel wire threading wire into the pipeline to be cleaned. During the pushing process, the sponge ball head enters the pipeline first and generates friction with the inner wall of the pipeline, and initially takes away some stains during the pushing process. Through the rotation of the automatic cleaning driving mechanism, the brush hair assembly can be driven to rotate through the metal soft rod to realize the brushing of the inner wall of the pipeline. During the continuous pushing process, the columnar sponge body can push the dirt in the pipeline forward until it is pushed out of the pipeline opening. During this process, cleaning liquid is injected into the bottle body, and the cleaning liquid flows into the silica gel sleeve through the hose. Since there are seals at both ends of the silica gel sleeve, the cleaning liquid can only flow out through the spray holes. The sprayed cleaning liquid directly acts on the inner wall of the pipeline, cooperating with the cleaning brush to achieve the cleaning of the pipeline. The metal soft rod that plays a role in supporting and pulling the entire cleaning brush is wrapped in the silica gel sleeve and will not directly contact the inner wall of the pipeline, so it will not cause wear to the inner wall of the pipeline. The brush head part uses a sponge ball head, which can not only play a cleaning role but also avoid the end of the metal soft rod from wearing the inner wall of the pipeline.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
