How to draw a stick figure of n95 protective mask?

Tools/raw materials: paper and pens. The method/steps are as follows:

1. First, draw the general outline of the socket cover.

2. Then, draw a detail line on the socket cover diagonally.

3. Then draw a metal strip on the nose.

4. Then add the masked model to the left in the middle of the mask.

5. Next, draw a hanging rope on the left side of the image.

6. Continue to add lanyards on the right side of the chart.

7. Finally, add an indent along the edge of the mask. "n" means oil resistance. "95" means that when exposed to a specific number of special test particles, the particle concentration inside the mask is lower than that outside the mask by more than 95%. You can see that the n95 protective mask is well mapped, and the problem is solved.
