After long-term use, the dust accumulated inside the multiplexer will affect the heat dissipation of the electronic devices inside the multiplexer.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: an optical fiber wavelength division multiplexer, comprising a multiplexer body, a wire insertion slot is provided on the multiplexer body, a heat dissipation mechanism with a filtering effect is provided on both sides of the multiplexer body, and a scraping mechanism is provided on the heat dissipation mechanism;

[0007] The heat dissipation mechanism includes a heat dissipation cavity, a through groove, a heat dissipation groove, an L-shaped plate, a filter hole and a collection groove. The heat dissipation cavity is opened on both sides of the multiplexer body, the through groove is arranged at the upper end of the heat dissipation cavity, the heat dissipation groove is arranged on the side wall of the heat dissipation cavity, the number of the heat dissipation cavities is several and evenly arranged, the L-shaped plate is arranged inside the heat dissipation cavity and slides in the through groove, the filter hole is arranged on the L-shaped plate, the number of the filter holes is several and evenly arranged, and the collection groove is arranged at the lower end of the L-shaped plate.

When in use, first the heat dissipation cavity can install the L-shaped plate, the L-shaped plate can slide in the through groove, and then the heat dissipation groove can dissipate heat for the electrical components inside the multiplexer body, and then the filter holes on the L-shaped plate can filter impurities in the air to prevent impurities in the air from entering the interior of the multiplexer body, and then the impurities on the L-shaped plate can be collected and processed in the collection groove.

[0019] Furthermore: the handle is provided with anti-skid grooves, and the number of the anti-skid grooves is several and arranged in a circle.

[0020] By adopting the above technical solution and providing the anti-skid groove, the anti-skid groove can increase the friction between the staff and the handle during use, so that the staff can better turn the handle and avoid hand slipping.

[0021] Furthermore: a plurality of the heat dissipation slots are arranged to be inclined downward.

[0022] By adopting the above technical solution and setting the shape of the heat dissipation groove, the heat dissipation groove is tilted downward when in use, which can prevent large impurities in the air from entering the heat dissipation cavity through the heat dissipation groove.

[0023] In summary, the utility model has the following beneficial effects:

[0024] By setting up the heat dissipation mechanism, when in use, first the heat dissipation cavity can install the L-shaped plate, the L-shaped plate can slide in the through groove, and then the heat dissipation groove can dissipate heat for the electrical components inside the multiplexer body, and then the filter holes on the L-shaped plate can filter impurities in the air to prevent impurities in the air from entering the interior of the multiplexer body, and then the impurities on the L-shaped plate can be collected and processed in the collection groove.

[0025] By setting up a scraping mechanism, when impurities clog the filter holes, lift the L-shaped plate upwards, and then rotate the rotating rod through the handle to make the limit plate separate from the scraping plate, and then rotate the scraping plate to make the brush on the scraping plate contact the filter holes, and then when the L-shaped plate continues to move upwards, the brush can clean the filter holes, and the cleaned impurities can be collected in the collection tank.

[0026] Based on the above improvements, the overall technical effect achieved by the device is that it can prevent impurities from the outside from entering the interior of the multiplexer body through the heat dissipation groove while dissipating the heat of the multiplexer body, thereby avoiding affecting the heat dissipation efficiency of the multiplexer body.
