[0003] However, although the optical fiber fusion splicer with a cooling mechanism in the prior art has achieved a cooling effect, it still has some shortcomings: the existing optical fiber fusion splicer generally heats the fused optical fiber and wraps it with a heat shrink tube before cooling it, while the above-mentioned device directly cools it inside the windshield of the fusion splicer, and then the heat shrink tube needs to be sleeved on the connection point, which makes it inconvenient to use. When the fusion splicer is working, a large amount of heat is stored inside, and blowing air to cool the inside cannot form a good ventilation effect, resulting in a deviation in the effect; secondly, the existing fusion splicer needs to clean the dust and oil on the surface of the optical fiber before fusing the optical fiber, otherwise it will affect the quality of the fusion. In the prior art, it is troublesome to manually prepare cleaning agents and cleaning cotton for wiping and cleaning. Utility Model Content

[0004] In order to overcome the defects of the prior art, a fiber optic fusion splicer with a cooling unit is provided to solve the problems that the prior fiber optic fusion splicer has poor cooling effect on the fiber after fusion and cannot pre-clean the fiber through the device itself.

[0005] To achieve the above-mentioned purpose, a fiber optic fusion splicer with a cooling unit is provided, comprising: a fusion splicer body and a cooling device, the fusion splicer body comprising a chassis, a windshield on the upper side of the chassis and a control panel connected to the outside of the chassis, the cooling device is arranged on the upper side of the chassis of the fusion splicer body, and the cooling device comprises a mounting block, and a cooling plate is arranged on the upper side of the mounting block, and placement grooves are arranged between the cooling plates, and a fan is arranged on the outer side of the cooling plate, a cleaning groove is opened on the upper side of the mounting block, and a cleaning sponge is arranged on the inner groove wall of the cleaning groove, and a liquid storage box is arranged on the outer wall of the mounting block, and an absorbent cotton strip is connected to the inside of the liquid storage box, and the absorbent cotton strip is connected to the absorbent cotton block connected to the outside of the cleaning sponge.

[0006] Furthermore, a metal mesh plate is provided at the inner bottom of the placement groove, and the upper end of the metal mesh plate does not exceed the upper end surface of the cooling plate.

Since the cleaning sponge absorbs alcohol solvent from the liquid storage box through the absorbent cotton block and the absorbent cotton strip, it is easy to clean the dust and oil on the surface of the light. Then open the wind shield to fix the light at the fusion point of the fusion splicer for fusion splicing, then open the wind shield to take it out, put on the heat shrink tube and place it in the heating plate of the fusion splicer, then take it out and put it in the placement tank. At this time, start the fan, and cool the optical fiber through the fan and the tortuous pipeline inside the cooling plate, as well as the rotating coolant in the pipeline.
