Problems solved by technology

Existing masks cannot prevent foreign matter such as saliva from leaking directly from the bottom of the mask, which may easily cause pollution and spread of viruses
And after wearing it, because the air cannot circulate, it feels suffocating, which is very uncomfortable.

preparation example Construction

[0027] The preparation method of the polyurethane fiber cloth containing titanium dioxide is as follows: immerse the polyurethane fiber cloth in the pretreatment solution for 40-60 minutes, take it out, and dry it to obtain the product.

[0028] The preparation method of the pretreatment liquid includes the following steps: add 30 parts by weight of PEG2000, 10 parts by weight of 1,6-hexamethylene diisocyanate, and 1 part by weight of 1,4-butanediol and react at 80°C for 3 hours, Then add 3 parts by weight of succinic acid and 0.5 parts by weight of dibutyltin dilaurate and react for 2 hours; finally add titanium dioxide nano powder and stir for 2-3 hours to obtain the product.

[0029] The mask body is provided with a rechargeable lithium battery, which is electrically connected to the fan, the controller, and the LED light respectively. The built-in lithium battery can be used for more than 8 hours on a single charge.

[0030] The mask also includes a lanyard, which is not p...

Embodiment 1

[0037] Such as figure 1 , a mask that can automatically filter gas and sterilize, comprising a transparent cover and a mask body; the mask body is sequentially provided with a fan, a filter element, and an LED light from the inside to the outside.

[0038] The material of the transparent cover is copolyester; the position of the transparent cover close to the face is silica gel; the mask body also includes a controller, which is used to intelligently control the running speed or start and stop of the fan; the control The controller includes a temperature and humidity sensor and a fan motor drive. When the temperature and humidity in the mask is lower than the lower limit of the pre-designed temperature and humidity, the controller controls the fan to stop running; when the temperature and humidity in the mask is below the pre-designed temperature and humidity Between, the controller controls the fan to run at a low speed; when the temperature and humidity inside the mask is hi...

Abstract

The invention belongs to the technical field of masks, and particularly relates to a mask capable of automatically filtering gas and sterilizing. The invention discloses a mask capable of automatically filtering gas and sterilizing. The mask comprises a transparent mask and a mask body, the mask body is sequentially provided with a fan, a filter element and an LED lamp from inside to outside. Themask is modularized, the filter screen can be replaced as required, and the built-in HEPA filter screen can be replaced from H10-H13; the fan is arranged in the mask and can automatically supply air,so that the user feels more comfortable and does not feel asphyxia. The mask is made of a transparent material, so that the visualization of the mouth and the face is realized; the skin-friendly material is in contact with the skin, so that any adverse effect on the skin is avoided; the LED lamp is arranged on the outermost layer of the mask, ultraviolet sterilization can be conducted, the sterilization capacity of 99.9999% is achieved, and full and comprehensive protection is achieved. A rechargeable lithium battery is arranged in the mask, the mask can be continuously used for 8H after beingcharged once, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of masks, more specifically, the invention relates to a mask that can automatically filter gas and can be sterilized. Background technique [0002] Masks are the most basic sanitary protective equipment to prevent saliva droplets from spreading outward and viruses and pollutants from invading the human body. Therefore, masks are widely used in industries such as medical and health care and catering services. Existing masks usually include a mask and hanging straps arranged on both sides of the mask. The mask is made of gauze layered to prevent the spread of saliva droplets, while preventing external pollutants, viruses, etc. from invading the human body. The lanyards are set on the wearer's ears to fix the mask on the wearer's face. Existing masks cannot prevent foreign matter such as saliva from directly leaking from the bottom of the mask, which is likely to cause pollution and spread of viruses. And a...
