Embodiment 1

[0033]In the above scheme, the left and right sides of the inner cap clamp are provided with clean air passages, the air inlet of the clean air passage is connected to the purified air inlet, and the air outlet at the front end of the clean air passage is provided with three wind direction guide pieces, the wind direction The guide vane is located at the air outlet of the purified air, and the wind direction guide vane is slightly inclined downward. The miniature silent fans installed on both sides of the cap suck in the air that has passed through the purified filter element from the outside, and discharge the purified air from the purified air outlet through the clean air channel. At this time, it can not only provide purified air for medical staff, It ensures that long-term intensive work is also comfortable, and effectively eliminates problems such as fogging of the goggle mask mirror, which blocks the line of sight and affects the treatment of patients by medical staff.

Embodiment 2

[0035] In another solution, the rear side of the inner cap clip is provided with a clean air channel, the air inlet of the clean air channel is connected to the purified air inlet, and at least three wind direction guide pieces are provided at the air outlet at the front end of the clean air channel. The wind direction guide piece is located at the air outlet of the purified air. The air outlets at the front end of the clean air channel are respectively located on the left and right inner sides of the protective mask. The miniature silent fan is installed on the back of the cap body. Similarly, the clean air channel is used to provide fresh air inside the cap body. The fan is located away from the ears on both sides, which again reduces the impact of the tiny sound produced by the fan on the medical staff.

Embodiment 3

[0037] In another solution, the top of the inner cap clip is provided with a clean air channel, the air inlet of the clean air channel is connected to the purified air inlet, and the air outlet of the clean air channel is arranged on the inside of the connection between the protective mask and the cap body. The air outlet of the clean air passage is provided with at least one air outlet, and the air outlet is located at the purified air outlet. The installation position of the miniature silent fan is changed to the top of the cap body, and the air purification channel is also connected to the air outlet hole inside the cap body from top to bottom. , and its defogging effect is even better.
