Compared with the existing masks, the electric mask adopts turbo centrifugal ventilation, which has large negative pressure and sufficient air volume. At the same time, through the shielding of the air inlet cover and the filter screen, the total pressure loss when the air enters is small.

[θθ16] 3. This electric mask is divided into three layers, which is very convenient to disassemble and clean, and it is also very convenient to replace the filter.

[0017] 4. The electric mask is very small in size and light in weight, and the user will not affect the appearance when using it.

[0018] 5. The electric mask wheel is circular, and the angle between the blades and the central axis is also 30°-75°. This angle design is obtained after many experiments. At this angle, the turbine wind-swing effect of the electric mask Optimal.

[0019] 6. The noise of the electric filter and the single-phase vent of the electric mask is very small, because if the noise is loud, it will make the user feel irritable, but this electric mask does not.
