[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] Example 1:

[0033] A protective cover for a CNC engraving and milling machine with heat dissipation function, such as Figures 1-5 As shown, the device includes a protective cover body 1. Multiple fans 7 are installed at the top inside the protective cover body 1, equidistantly distributed. The fans 7 generate airflow when activated, effectively dissipating heat from inside the engraving and milling machine, thus reducing internal heat. A second dustproof net 6 is installed at the bottom of the protective cover body 1 to prevent flying debris from entering the fans 7 and damaging the fan blades. The second dustproof net 6 is angled, and the bottom of the protective cover body 1 is sloped. This slope, along with the angled second dustproof net 6, places the second dustproof net 6 on the shaded side relative to the workpiece, reducing the likelihood of debris flying towards and clogging the second dustproof net 6. A guide groove 3 with a "T"-shaped cross-section is formed on the outer surface of the protective cover body 1. A handle 4 runs through the outer surface of the guide groove 3. The handle 4 is slidably connected to the guide groove 3, allowing the operator to slide the handle 4 laterally. During the sliding process, the handle 4 is limited and guided by the guide groove 3. A strong magnet 10 is installed inside the handle 4. A linkage block 8 is connected to the back of the protective cover body 1. An adsorption block 9 is fixed below the outer surface of the linkage block 8. The adsorption block 9 is made of iron. When the handle 4 slides, the magnetic field of the strong magnet 10 causes the adsorption block 9 to move along with the handle 4, thereby causing the linkage block 8 to move. A scraper 11 is connected to the middle of the outer surface of the linkage block 8. The scraper 11 is in contact with the viewing window 2. A brush 12 is connected to the top of the linkage block 8. The brush 12 is in contact with the second dustproof net 6. After the linkage block 8 moves, it drives the scraper 11 to move towards the viewing window 2 and also drives the brush 12 to move to clean the second dustproof net 6.

[0034] See Figures 1-3 In the above embodiment, a viewing window 2 is installed inside the protective cover body 1 to facilitate staff to view the milling process; the viewing window 2 is made of tempered glass, which has high strength and good impact resistance, is not prone to cracking, avoids long-term impact from affecting observation, and has a long service life; a first dustproof net 5 is installed on the top of the outer surface of the protective cover body 1 to prevent external dust from entering the interior of the protective cover body 1 through the top of the outer surface of the protective cover body 1 when the fan 7 is stopped.

[0035] Example 2:

[0036] On the basis of the above embodiment one, in order to deal with different situations, now through the following settings.

[0037] Reference Figures 1-3 In the above embodiment, the window 2 is a thickened acrylic plate, which is more flexible than tempered glass and is not easy to break after being hit, thereby reducing the phenomenon of secondary injury caused by the breakage of the window 2.

[0038] The implementation principle of the utility model is: first, the protective cover main body 1 is installed on the engraving and milling machine, the worker can check the engraving and milling condition through the window 2, and the airflow is generated by starting the fan 7, so that the heat inside the engraving and milling machine is blown out, thereby reducing the heat inside the engraving and milling machine, and the second dust screen 6 is used to avoid the splashing debris from entering the fan 7 and damaging the fan blade, and the bottom of the protective cover main body 1 is inclined and the second dust screen 6 is inclined, so that the second dust screen 6 is in the shady side relative to the workpiece, reducing the phenomenon of debris flying to the second dust screen 6, to slow down the phenomenon of debris blocking the second dust screen 6;

[0039] When the window 2 is blurred and affects observation or the second dust screen 6 is blocked, the worker can slide the handle 4 horizontally, the handle 4 is limited and guided by the guide groove 3 in the sliding process, and the handle 4 is displaced by the magnetic field of the strong magnet 10 when sliding, so that the adsorption block 9 is displaced together with the handle 4, thereby displacing the linkage block 8, and the scraper 11 is displaced to the window 2 after the linkage block 8 is displaced, and the brush 12 is displaced to clean the second dust screen 6.
