[0028] To better understand the purpose, structure, and function of this utility model, the following description is in conjunction with the appendix. Figures 1 to 6 The present invention provides a more detailed description of an optical fiber end-face cleaning device.

[0029] like Figures 1 to 6As shown, an embodiment of the present invention provides an optical fiber end-face cleaning device, including an air filter assembly. The output end of the air filter assembly is connected to a first pressure reducing valve 110 via a pipe. The first pressure reducing valve 110 is connected to a mechanically controlled valve 120 via a pipe. The mechanically controlled valve 120 is connected to a liquid storage tank 150 via a pipe. The liquid storage tank 150 is connected to one end of a cleaning pipe 500 via a liquid output pipe 130. The other end of the cleaning pipe 500 is connected to a cleaning handle 600. The end of the cleaning handle 600 away from the cleaning pipe 500 is connected to an optical fiber connector 610. The liquid storage tank 150 is used to output cleaning fluid. The liquid storage tank 150 is provided with a liquid inlet, and a liquid storage cap 151 is movably connected to the liquid inlet. The liquid inlet is used to inject liquid, such as ethanol, for cleaning the optical fiber end face into the liquid storage tank 150.

[0030] The air filter assembly is also connected to a second pressure reducing valve 210 via a pipe. The second pressure reducing valve 210 is connected to a cleaning pipe 500 via a pipe and is used to output gas blown toward the end face of the optical fiber.

[0031] The air filter assembly is connected to the vacuum generator 310 via a pipe, and the vacuum generator 310 is connected to the cleaning pipe 500 via a pipe. The vacuum generator 310 is used to extract gas and / or liquid from the cleaning pipe 500.

[0032] In operation, air is filtered by the air filter assembly and then enters the first pressure reducing valve 110 through a pipe. This pressure reducing valve provides a certain air pressure source for the liquid output from the liquid storage tank 150. After receiving a certain air pressure, the liquid storage tank 150 outputs the internal liquid through a pipe to the cleaning pipe 500. The liquid in the cleaning pipe 500 then flows through the cleaning handle 600 to the fiber optic connector 610, and is finally sprayed onto the end face of the fiber optic cable to be cleaned by the fiber optic connector 610. To facilitate stable cleaning, the fiber optic cable is also fixed to the fiber optic connector 610, making the cleaning more efficient. The first pressure reducing valve 110 used here can be a suitable product available on the market, such as the SMC brand pressure reducing valve model ARG20-02G1H-B.

[0033] When gas needs to be blown onto the fiber optic end face, the air is filtered by the air filter assembly and then enters the second pressure reducing valve 210 through a pipe. The second pressure reducing valve 210 then delivers the pressurized air through the pipe to the cleaning pipe 500, from where it is delivered to the fiber optic connector 610, and finally blown onto the fiber optic end face. The second pressure reducing valve 210 can be the same pressure reducing valve as the first pressure reducing valve 110.

[0034] If liquids or other substances need to be removed from the fiber optic end face after cleaning, a certain positive air pressure is provided to the vacuum generator 310 through the air filter assembly, causing a certain negative pressure to be generated at the suction port of the vacuum generator 310. The suction port of the vacuum generator 310 is connected to the cleaning pipe 500, thus enabling the fiber optic connector 610 to remove liquids or other substances from the fiber optic end face. The vacuum generator 310 used here can be a suitable product available on the market, such as a vacuum generator from the SMC brand.

[0035] The above design enables the fiber optic end-face cleaning device to not only blow air, spray liquid, and suck air on a single machine, greatly improving the applicability of the cleaning device.

[0036] In this invention, the input end of the air filter assembly is also connected to a gas input connector 410, which is used to connect to an external gas input device, providing an interface for the external gas input device. Furthermore, the air filter assembly includes an air filter 420, an oil mist separator 430, a micro-mist separator 440, and a gas output connector 450. The input port of the air filter 420 is connected to the gas input connector 410, the output port of the air filter 420 is connected to the input port of the oil mist separator 430, and the output port of the oil mist separator 430 is connected to the input port of the micro-mist separator 440. This design allows for multiple filtrations of the air through different components, reducing the impurity content in the gas output by the air filter assembly and improving the reliability and service life of subsequent components. The air filter 420 can use an SMC AF20-02-A filter with a filtration accuracy of 5μm; the oil mist separator 430 can use an SMC AFM20-02-A device with a filtration accuracy of 0.3μm; and the micro-mist separator 440 can use an SMC AFD20-02-A device with a filtration accuracy of 0.01μm. All three components are SMC brand, allowing for connection via original manufacturer connectors. This not only reduces the overall size of the air filter assembly but also improves its reliability.

[0037] The output port of the mist separator 440 is connected to a gas output connector 450, which has two gas output ports. The gas output connector 450 is used to output the air filtered by the mist separator 440. For the purpose of subsequent gas use and simplifying pipeline layout, the gas required for blowing and spraying liquid is provided through one gas output port of the gas output connector 450, and the gas used for suction is provided through the other gas output port of the gas output connector 450.

[0038] As part of the air filtration assembly, the gas output connector 450 delivers air filtered by the air filter 420, oil mist separator 430, and micro-mist separator 440 to devices such as the first pressure reducing valve 110, the second pressure reducing valve 210, and the vacuum generator 310.

[0039] In this invention, one output port of the gas output connector 450 is connected to a gas splitter via a fourth gas pipe 460. The gas splitter has two output ports. One output port of the gas splitter is connected to the first pressure reducing valve 110 via a pipe, and the other output port of the gas splitter is connected to the second pressure reducing valve 210.

The mechanically controlled valve 120 is manually controlled, allowing the user to control whether to spray cleaning liquid onto the fiber optic end face. The mechanically controlled valve can use an SMC device with model number 120VM131F-01-34R.

[0041] A second solenoid valve 220 is also provided between the second pressure reducing valve 210 and the cleaning pipe 500. The second pressure reducing valve 210 and the second solenoid valve 220 are connected through a second gas pipe 230, and the second solenoid valve 220 is also connected to the cleaning pipe 500 through the second gas pipe 230. The second solenoid valve 220 allows the user to control its on / off state, thereby controlling whether air needs to be blown onto the fiber optic end face.

[0042] In this invention, a third solenoid valve 320 is connected between the other output port of the gas output connector 450 and the vacuum generator 310. The pipe connecting the gas output connector 450 and the third solenoid valve 320 is a third gas pipe 330. A third one-way valve 340 is provided between the vacuum generator 310 and the cleaning pipe 500. The third one-way valve 340 is connected to the vacuum generator 310 via the third gas pipe 330, and also to the cleaning pipe 500 via the third gas pipe 330. The purpose of the third solenoid valve 320 is to allow the user to control whether suction is needed. The purpose of the third one-way valve 340 is also to prevent gas backflow from damaging the vacuum generator 310.

[0043] The cleaning handle 600 is equipped with a handle liquid solenoid valve. One end of the handle liquid solenoid valve is connected to the cleaning pipe 500, and the other end is connected to the optical fiber connector 610. When not in use, the handle liquid solenoid valve can prevent the outflow of cleaning liquid, avoiding the leakage of residual cleaning liquid from the cleaning pipe 500 and the cleaning handle (600) when cleaning is not being performed, thus saving cleaning liquid and reducing environmental pollution. This handle liquid solenoid valve can be an SMC brand VDW12 series liquid solenoid valve.
