A top plate 10 is fixedly installed on the top of the latch 8. The top plate 10 is slidably connected to the connecting shell 3. A limiting groove 11 is provided on the inner side of the connecting shell 3. The limiting groove 11 is in a J-shape. An insert block 12 is inserted on the inner side of the limiting groove 11. A dust filter plate 13 is fixedly installed on the surface of the insert block 12. During the operation of the fan 5, the dust filter plate 13 will intercept impurities and dust in the air. After being used for a long time, a large amount of dust and impurities will accumulate on the surface of the dust filter plate 13, which will affect the air intake efficiency. Therefore, the dust filter plate 13 needs to be cleaned.

[0025] Embodiment 2

[0026] See also Figure 2 , 4 A connecting column 14 is slidably connected to the inner side of the base 1, and a thread is provided on the surface of the connecting column 14. The thread provided on the surface of the connecting column 14 meshes with the thread on the inner side of the threaded sleeve 17. A clamping plate 15 is fixedly installed at the bottom end of the connecting column 14, and a pad 16 is fixedly installed on the inner side of the clamping plate 15. The pad 16 is made of natural rubber. The surface of the connecting column 14 is threadedly connected to the threaded sleeve 17.

[0027] Working principle: When the eye protection desk lamp is working, the heat sink 6 will conduct the heat of the lamp head 2 under the action of heat conduction, and then start the fan 5 and absorb the external airflow into the inner side of the connecting shell 3 through the dust filter plate 13, so as to increase the air flow rate on the surface of the heat sink 6 and provide an effective heat dissipation effect for the lamp head 2. During the operation of the fan 5, the dust filter plate 13 will intercept impurities and dust in the air. When the dust filter plate 13 needs to be maintained and cleaned, first press the dust filter plate 13 downward, then move and rotate the dust filter plate 13 and drive the plug 12 to slide on the inner side of the limit groove 11, and slide the plug 12 along the limit groove 11 until it is pulled. The spring 9 and the top plate 10 will drive the plug block 12 and the dust filter plate 13 to separate from the connecting shell 3. During installation, first insert the plug block 12 through the limiting groove 11, then press down the plug block 12 and the dust filter plate 13 and rotate them, and then under the action of the tension spring 9 and the top plate 10, the plug block 12 will be driven to be stuck on the inner side of the limiting groove 11. At this time, the installation of the dust filter plate 13 is completed. When installing the eye-protection desk lamp, first place the place to be clamped between the clamping plate 15 and the base 1, then rotate the threaded sleeve 17 and drive the connecting column 14 to slide on the inner side of the base 1 under the action of the thread, and at the same time drive the clamping plate 15 close to the base 1, so that it can be clamped at the place where it needs to be clamped.
