Problems solved by technology

This kind of mask and respirator will cause many inconveniences during use, such as: difficulty in breathing, difficulty in wearing glasses, and inability to use in high temperature environments, etc.
Since the main airflow channel needs to be filtered layer by layer, the airflow is not smooth. Therefore, once the mask or respirator is not tightly combined with the user's face, side leakage is easy to occur, let alone filtering bacteria and viruses.

Embodiment 1

[0026] Embodiment 1, since the current packaged volume and weight of the ultraviolet LED can be controlled as required. For example, the weight of the currently tested UV LED can be controlled at about 0.5 grams, and the volume can be less than 5*5*2.5 mm (that is, length*width*height). Therefore, it is completely feasible to bury the UV LED in the mask and let the air flow pass through the surface of the UV LED to sterilize and disinfect.

[0027] Present embodiment promptly proposes a kind of mouth mask that adopts ultraviolet LED design, as figure 1 As shown, it at least includes an outer layer 1 , an inner layer 2 , an interlayer 3 and an ultraviolet LED layer 4 . Wherein, the interlayer 3 and the ultraviolet LED layer 4 are preferably built into the chamber surrounded by the outer skin 1 and the inner skin 2, and the edge of the outer skin 1 and the edge of the interlayer 3 can also be sealed, and then the inner skin 2 is pasted or Fasten on the inner side of the interl...

Abstract

The invention discloses a mask which comprises an outer surface layer, an inner surface layer, an ultraviolet LED (light-emitting diode) layer and an interlayer, wherein the ultraviolet LED layer is arranged between the outer surface layer and the inner surface layer, is coated on the interlayer and comprises an ultraviolet LED chip or an ultraviolet LED lamp, and a power supply circuit of the ultraviolet LED chip or the ultraviolet LED lamp is paved on the interlayer or inside the interlayer. The mask can really play a role of killing bacteria and virus and is small, exquisite and light and convenient to wear. A high-radiation density ultraviolet LED is in a hidden design and does not hurt the skin. Airflow is smooth due to the absence of the baffle of textile fabrics layer by layer; the mask is comfortable to wear, and the air leakage phenomenon can be greatly reduced. If a gas check valve switch is further arranged in the mask, the ultraviolet LED is lightened only in the process of inspiration or expiration, so that the service life of the ultraviolet LED is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of masks or respirators, and in particular relates to a mask or a respirator that can effectively filter viruses and bacteria in the air. Background technique [0002] Virus particles are very small, generally less than 0.3 microns in diameter. The masks currently used, whether they are medical masks (represented by various types of surgical masks of the 3M company in the United States) or ordinary civilian masks, are all made of textiles. The fabric mesh of the mask is ineffective at isolating viruses and bacteria floating in the air. Despite this, masks are still commonly used in hospitals and daily life, because wearing masks can block the spread of liquid droplets in the mouth and nasal cavity, and can prevent dirty hands from accidentally touching the mouth and nose, bringing bacteria or viruses into the to the human body. [0003] If it is required to filter out bacteria and viruses in the air, it i...
