Referring to fig. 1 and 2, a letter-type glasses mask according to an embodiment is shown, which includes a mask body 1 covering at least from the chin to the eyebrow arch, a window 4 located at the upper portion 2 of the mask body 1, a one-way exhalation valve 5 located at the middle lower portion 3 of the mask body 1, and a string 6 fixed at both sides of the mask body 1, wherein a letter-type disinfection device 7 for disinfection is installed inside the mask body 1 and at least above the window 4.

The mask body 1 and the window 4 can be made of medical plastics, the mask body 1 can be opaque, and the window 4 needs to be made into a transparent state for the user to observe. Gauze mask body 1 sets up joint strip 8 with head contact segment, and joint strip 8 needs use the material preparation harmless not allergic to the human body for form confined space between gauze mask body 1 and the head after the glasses gauze mask has worn. When in inspiration, the air is inhaled through the bypass type disinfection device 7, and when in expiration, the air is exhaled outwards through the one-way exhalation valve 5.

The letter type disinfection device 7 rapidly filters, disinfects and disinfects the inhaled air, and finally supplies the disinfected air to a user, thereby effectively playing a virus isolation function. The rope belts 6 can be made into the mask body 1, two sides of which are respectively provided with an ear-hanging rope belt, and the ear-hanging rope belts are respectively sleeved on the left ear and the right ear when the mask is worn; or can be made into a whole elastic rope belt which can be worn by sleeving the head.

Of course, in other embodiments, the upper portion 2 and the window 4 of the mask body 1 may be made of medical plastics, and the lower portion 3 of the mask body 1 may be made of flexible materials, so that the lower portion 3 of the flexible materials is folded into the upper portion 2 when the glasses mask is not used, thereby facilitating the storage of the whole glasses mask.

Referring to fig. 2, 3 and 4, in the present embodiment, the ducted sterilizing device 7 includes a ducted casing 71 fixed inside the mask body 1, air inlet pipes 72 respectively disposed at two ends of the ducted casing 71, a sterilization generator 73 installed inside the ducted casing 71, a sterilization coating 76 coated on an inner wall of the ducted casing 71, and a detachable filter paper 75 covering the sterilization coating 76, wherein the filter paper 75 may be a common physical filter paper, and an air outlet 74 is disposed at the bottom of the ducted casing 71. The intake pipe 72 is arranged in carrying the outside air of gauze mask body 1 to letter way shell 71, and the generator 73 that disinfects is used for carrying out high efficiency to the air and disinfects, and bactericidal coating 76 and filter paper 75 all are used for carrying out preliminary germ to the air and filter and disinfect when the air gets into letter way shell 71 from intake pipe 72.

In this embodiment, the air outlet direction of the one-way exhalation valve 5 is outward, the air inlet pipe 72 is provided with a one-way valve 721, and the air outlet direction of the one-way valve 721 is inward. The mask body 1 is not breathable, and a sealed space is formed between the mask body and the head, so that air can only enter through the air inlet pipe 72 and be discharged through the one-way exhalation valve 5, and the isolation effect is further improved.

In this embodiment, the air inlet pipe 72 penetrates and extends to the outside of the mask body 1, and during breathing, air outside the mask body 1 enters the casing 71 through the air inlet pipe 72.

In this embodiment, still include battery 9 and the switch 10 of installing on gauze mask body 1, pass through the connection of electric wire between battery 9, switch 10 and the generator 73 that disinfects respectively, open switch 10 when wearing the gauze mask and make the generator 73 that disinfects work and disinfect the air that gets into in letter shell 71. The mask body 1 is also provided with a battery bin for installing a battery (because the battery bin is an over-prior art, the battery bin is not shown, is not marked, but does not influence the effect of the glasses mask body), the battery 9 and the switch 10 can be arranged at any position of the mask body 1, and the installation position can be determined by the operation convenience.

In this embodiment, the detachable filter pulp 722 is provided in the front and/or rear part of the check valve 721 in the air inlet pipe 72. Larger particles and pollutants in the air can be filtered, and the air filtering effect is further improved.

In this embodiment, the sterilization coating 76 is an aluminum layer for blocking the ultraviolet rays emitted from the sterilization generator 73, and the ultraviolet rays may cause skin cancer when being irradiated on the skin of the human body for a long time, so that the aluminum layer blocks the ultraviolet rays from irradiating the human body, and the safety of the human body is protected. The sterilization generator 73 is an ultraviolet mercury lamp, a deep ultraviolet LED lamp or an ultraviolet lamp with a wavelength of 250-270 nm. The sterilization coating 76 can effectively kill part of viruses, then kill the rest of viruses through the sterilization generator 73, and especially, an ultraviolet lamp with the wavelength of 250-270 nm has a good effect of killing coronavirus and RNA viruses.

The features and functions of the present invention will be further understood from the following description.

The embodiment also provides a working method of the letter channel type glasses and mask, wherein the working method comprises the following steps:

the user wears the glasses and mask and turns on the switch 10.

When inhaling, the air enters the bypass casing 71 from the air inlet pipe 72, the sterilization generator 73 performs sterilization and disinfection on the air, and the air is discharged to the sealed space from the air outlet 74 for the user to breathe after the sterilization and disinfection is completed; the air is purified, sterilized and disinfected in a bypass type sterilization mode.

When the respirator exhales, the air coming out of the oral cavity or the nasal cavity of the user is exhaled to the outside of the glasses and the mask through the one-way exhalation valve 5.

The human breath, the lung capacity is 2500ml-3500ml, can kill RNA virus in less than 1 second under the irradiation of 30000uW per square centimeter intensity, the air outside the mask is filtered by the physical layer and sterilized by ultraviolet rays in the duct space, the fresh air after filtering and sterilization not only stops the possibility of the suction of pathogenic bacteria, but also reduces the secondary transmission to the maximum extent and protects the self health.

In addition, a micro generator is installed in the one-way expiratory valve 5, a motor shaft of the micro generator is provided with a micro fan blade, the micro generator can be connected with the battery compartment, and when the user exhales, the micro fan blade rotates, the micro generator generates electricity to charge the battery compartment, so that the power supply of the sterilization generator is realized. Of course, the micro generator can also be directly connected with the sterilization generator through an electric wire, and the sterilization generator is directly powered in the power generation process.

In conclusion, the invention arranges the letter type disinfection device in the glasses mask to rapidly filter, sterilize and disinfect the sucked air, and finally supplies the sterilized and disinfected air to the user, thereby effectively playing a virus isolation function and avoiding the possibility of bacteria suction. Set up one-way expiratory valve on the gauze mask body for form sealed space between gauze mask body and the head, only exhale through one-way expiratory valve, the gauze mask body is airtight, even the phenomenon that pollutant can not take place to pollute yet and delay, secondary contact propagates outside the gauze mask body, and secondary propagation has been reduced to the at utmost, and protection self is healthy.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
