When a user wears the mask 3, the reverse folding part 26 is attached to the face and forms an included angle with the back of the upper edge 25 of the mask, when exhaled air goes upwards, the reverse folding part 26 can guide the air to be folded back, and the air is scattered from other directions of the mask. The lower edge of the reverse folding part does not exceed the nose tip position of the face of the human body, so that all gas exhaled through the nose enters the reverse folding part 26 to be folded.

The utility model discloses accomplish the fan box by the manufacture factory and predetermine the procedure setting, the utility model discloses a medical facial protector application description:

the wearing sequence of the device is as follows: mask → goggles → face screen, the mask wearing mode is with ordinary mask, wear the goggles before with ventilative net according to embedding ventilative window (fig. 5), after wearing the goggles, adjust the clamp plate position, make its bilateral symmetry in the two sides of the alar part of nose, withhold on the gauze mask on the reason for the reason is hugged closely on the gauze mask on the reason and is held the alar both sides of nose. The face screen is worn, the user can start the face screen by pressing a switch, hear the voice prompt of the loudspeaker to enter a starting state, then wear the face screen, the spongy cushion is arranged above the forehead, the baffle completely covers the goggles and the front of the mask and leaves a certain gap, and the position of the fan is adjusted to enable the fan to be over against the air holes above the glasses frame. Because the upper edge of the mask is tightly buckled and pressed on the face parts at the two sides of the nose wing by the pressing plate, the exhaled air is ensured to leak upwards along the nose wing rarely; due to the existence of the reverse folding part, the exhaled air can not be diffused from the upper edge of the mask, the upward hot air is further reduced, and the probability of lens atomization is reduced. Along with the extension of the wearing time, the temperature and the humidity of the forehead of the wearer rise to reach preset threshold values, if the temperature is between 38 ℃ and 39 ℃, the probe transmits the information to the temperature sensor and the humidity sensor → the CPU, the CPU sends a working instruction to the micro fan, and the micro fan drives the fan to operate. The fan blows downwards, and the convection of air inside and outside the picture frame is accelerated to the ventilative net of air current accessible, and the fog appears in the hot air gathering in not only avoiding the picture frame, still can in time reduce skin temperature and humidity in the picture frame. The air flow can also directly convect downwards along the lens to prevent the upward flow of the exhaled hot air, effectively prevent the contact and fogging of the hot air and the lens, and promote the discharge of the hot air in the mask. If the temperature is higher than 39 ℃, the CPU sends an instruction to the loudspeaker to prompt that the ambient temperature is too high, and the user is advised to have a rest immediately. If the temperature and humidity of the fan are within the preset normal range (such as 36-37.9 ℃) after the fan works for a period of time, the CPU sends a work stopping instruction to the micro fan, and the fan stops working and is in a standby state again. If the electric quantity is less than 20%, the information of low electric quantity is transmitted to the CPU, and the CPU sends an instruction to the loudspeaker to prompt that the electric quantity is supplemented in time. When the wearing is finished, the patient can remove the breathable net and discard the breathable net, and the rest parts can be sterilized for use.

The device is not only suitable for combined use, but also has great application value when each part is used independently, and the dehumidification and heat dissipation effects are better when the panel is used independently; when the goggles are used independently, the ventilation effect is better; if the mask is used independently, the atomization of the user wearing the myopia glasses can be reduced to a certain degree. Except that the breathable net needs to be replaced when used every time, other parts can be repeatedly used after being disinfected, and the breathable net can be used for a long time by regularly and simply maintaining when necessary, is low in use cost, saves medical materials and has little harm to the environment.

Above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, a plurality of modifications and decorations without departing from the principle of the present invention should be considered as the protection scope of the present invention.
