Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The first embodiment is as follows:

this embodiment is described below with reference to fig. 1 to 5, and a multifunctional mask includes a mask body 1, an air circulation mechanism 2, a straw hole mechanism 3, a nasal layering 4, a mask belt 5, and a color-changing indication strip 6, the middle portion of the mask body 1 is fixedly connected with the air circulation mechanism 2, the straw hole mechanism 3 is fixedly connected to the mask body 1, the straw hole mechanism 3 is located under the air circulation mechanism 2, the nasal layering 4 is fixedly connected to the upper portion of the mask body 1, the mask belt 5 is fixedly connected to both sides of the mask body 1, and the two color-changing indication strips 6 are adhered to the inner wall of the mask body 1. Can guarantee through setting up circulation of air mechanism 2 that there is continuous sufficient air inside the gauze mask, can not lead to the fact the difficulty of breathing in because of inside negative pressure to can filter gas, can drink water or beverage when wearing the gauze mask through setting up straw hole mechanism 3, reduced the possibility at crowded place cross infection of people's stream, can remind people to need to change the gauze mask through the change of 6 colours of color-changing indicator strip.

The second embodiment is as follows:

the following describes the present embodiment with reference to fig. 1 to 5, and the present embodiment further describes the first embodiment, the air circulation mechanism 2 includes a housing 201, a filter 202, a micro fan 203, a guard 204, a button 205 and a protective cover 206, the housing 201 is fixedly connected to the middle portion of the mask body 1, the filter 202 is fixedly connected to the inside of the housing 201, the guard 204 is fixedly connected to the housing 201, the micro fan 203 is arranged between the guard 204 and the filter 202, the button 205 is arranged on the guard 204, the micro fan 203 is electrically connected to the button 205, and the protective cover 206 is fixedly connected to the outer surface of the housing 201. During the use, the air is purified through filter screen 202, and is inhaled inside the gauze mask through micro fan 203 again to guaranteed that there is sufficient air that lasts inside the gauze mask for the people to breathe, avoided because of the inside negative pressure of gauze mask, the sensation of breathing difficulty that the air can't cause often.

The third concrete implementation mode:

the embodiment will be described with reference to fig. 1 to 5, and the second embodiment is further described in the present embodiment, where the straw hole mechanism 3 includes a straw hole 301, a moisture absorption ring 302, a sealing cover 303 and a knob 304, the straw hole 301 is fixedly connected to the mask body 1, the straw hole 301 is located right below the housing 201, the moisture absorption ring 302 is disposed in the straw hole 301, the sealing cover 303 is rotatably connected to an outer surface of the straw hole 301, and the knob 304 is fixedly connected to the sealing cover 303. When water or beverage needs to be drunk, the sealing cover 303 is opened by manually rotating the knob 304, then the straw is inserted into the straw hole 301, and the straw is taken out after drinking, so that the residual liquid can be adsorbed by the moisture absorption ring 302, and the possibility of cross infection is avoided.

The fourth concrete implementation mode:

The fifth concrete implementation mode:

the present embodiment will be described with reference to fig. 1 to 5, and the fourth embodiment will be further described, in which the color change indicator strip 6 is a humidity-sensitive indicator strip. Because human breathing produces moisture, and then attaches to on the indicator strip 6 that discolours, the chemical reaction takes place for exhaled molecule and the indicator strip that discolours, and when the live time overlength, humidity sensitive indicator strip colour changes, is convenient for remind people to need to change the gauze mask.

The utility model discloses a multifunctional mask, its theory of operation is:

when in use, air is purified by the filter screen 202 and then sucked into the mask by the micro fan 203, thereby ensuring that the inside of the mask has continuous sufficient air for people to breathe, avoiding the feeling of difficult breathing caused by the fact that the air can not enter due to the negative pressure inside the mask, when water or beverage needs to be drunk, the sealing cover 303 is opened by manually rotating the knob 304, then the straw is inserted into the straw hole 301, the straw is taken out after drinking, the residual liquid can be absorbed by the moisture absorption ring 302, the possibility of cross infection is avoided, because the breath of the human body generates moisture and then adheres to the color-changing indicator strip 6, the exhaled molecules and the color-changing indicator strip generate chemical reaction, when the service life is too long, the color of the humidity sensitive indicating strip is changed, people can be reminded of replacing the mask conveniently, the nose area and the face contour area can be tightly matched through the nose pressing strip 4, and virus infection caused by air leakage is avoided.

Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or replacements made by those skilled in the art within the scope of the present invention also belong to the protection scope of the present invention.
