[0033] See also Figure 1-2A dust mask for electrical equipment maintenance, comprising an eye protection mask 1, a mouth protection mask 8 is fixedly installed in the middle of the bottom of the eye protection mask 1, an upper ventilation port 10 is fixedly installed in the middle of the front side of the mouth protection mask 8, a lower ventilation port 9 located below the upper ventilation port 10 is fixedly installed in the middle of the front side of the mouth protection mask 8, and side ventilation ports 11 are fixedly installed on the left and right sides of the mouth protection mask 8. Air outlets are provided on the lower ventilation port 9, the upper ventilation port 10 and the side ventilation port 11, and filter cotton is fixedly installed inside the lower ventilation port 9, the upper ventilation port 10 and the side ventilation port 11. The function of the filter cotton is mainly to isolate dust in the air. Dust, if you feel difficulty breathing when using the mask, you need to replace the filter cotton with a new one. Buckles 12 are fixedly installed on the top of both sides of the mouth protection cover 8, and an elastic headband 7 is fixedly sleeved on the buckle 12. The left and right sides of the inner cavity of the eye protection cover 1 are movably sleeved with movable rods 4, and the movable rod 4 is movably sleeved with a second elastic member 13 located between the vertical part of the movable rod 4 and the inner cavity of the eye protection cover 1. The other side of the movable rod 4 penetrates and extends to the outside of the eye protection cover 1 and is fixedly connected to the telescopic rod 14. A rotating block 6 is fixedly installed on the other side of the telescopic rod 14. There are two rotating blocks 6, and both rotating blocks 6 are provided with anti-slip grooves. The inner side of the rotating block 6 The upper and lower sides of the surface are fixedly installed with a card block 15, and a card slot adapted to the card block 15 is opened on the mounting block 5. The eye protection shield 1 is fixedly installed with a mounting block 5 located on the periphery of the movable rod 4 on both sides. The number of movable rods 4 is two, and the inner side surfaces of the two movable rods 4 penetrate and extend to the inside of the eye protection shield 1 and are fixedly connected by a connecting rod 2. The connecting rod 2 is cylindrical in design, and a first elastic member 17 is fixedly installed in the inner cavity of the connecting rod 2. The other side of the first elastic member 17 is fixedly connected to the cleaning plate 3. By setting the mounting block 5 and the card block 15, when the water mist in the inner cavity of the eye protection shield 1 is cleaned, the card block 15 is inserted into the mounting block 5. The cleaning plate 3 is fixed to the top of the inner cavity of the eye protection shield 1 in the card slot opened in the cavity, so as to prevent the cleaning plate 3 from blocking the user's sight and preventing the rotating block 6 from accidentally touching and changing the position of the cleaning plate 3, which is very convenient. Bristles 16 are arranged on the other side of the cleaning plate 3, and the inner cavity of the connecting rod 2 is movably sleeved with the cleaning plate 3. The bristles 16 are driven to rotate by the rotation of the connecting rod 2, and the water mist formed in the inner cavity of the eye protection shield 1 is cleaned by the bristles 16. Due to the elastic effect of the second spring 17, when the bristles 16 contact the eye protection shield 1, the bristles 16 and the inner cavity of the eye protection shield 1 are in a tightly fitted state, thereby improving the efficiency of the bristle cleaning.

[0034] Working principle: first, wear the entire mask at a suitable position on the face, put the elastic headband 7 on the head, and adjust the mask to a suitable position. When water mist appears in the inner cavity of the eye protection shield 1, pull out the rotating block 6 and rotate the rotating block 6, then the cleaning plate 3 rotates, and the bristles 16 provided on the cleaning plate 3 are used to clean the water mist in the inner cavity of the eye protection shield 1 to prevent the water mist from affecting people's vision. Due to the elastic effect of the first elastic member 17, when the bristles 16 contact the eye protection shield 1, the bristles 16 and the inner cavity of the eye protection shield 1 are in a tightly fitted state, thereby improving the cleaning efficiency of the bristles 16. When the water mist in the inner cavity of the eye protection shield 1 is cleaned, rotate the rotating block 6 so that the cleaning plate 3 is located at the top of the inner cavity of the eye protection shield 1, and then push the rotating block 6 in the direction of the mounting block 5, then the clamping block 15 is clamped into the slot opened in the inner cavity of the mounting block 5, so the connecting rod 2 is firmly fixed.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
