Description
Technical Field
The invention relates to a mask, in particular to a mask with an increased surface area, which can prevent the mask from blocking most of air when a user exhales or inhales, and further can enable the user to easily exhale and inhale when wearing the mask.
Background
With the development of industry and the progress of traffic, waste gas discharged from factories and vehicles exists in the living environment, the waste gas affects the ecological environment and pollutes the air more seriously, so that people are affected by haze for a long time, and people can wear the mask to go out when going out to work, go to school, travel or shop in order to avoid the harm to the health of people caused by the pollutants and bacteria in the air.
Wherein, the gauze mask is used for wearing in user's mouth nose department, make the user when absorbing outside air, the dirty and bacterium in gauze mask ability separation and the filter space, let the user breathe clean air, and, when the user is from the mouth spit gas, the gauze mask also can filter the gas that the user exhaled in order to avoid the germ to scatter in the air and infect other people, however, because the gauze mask that at present mostly sells is worn in user's mouth nose department, the physique size of gauze mask will not have too big change, and then when the user carries out the exhaling and inhales, the gauze mask only has specific region to let gas pass through, and then the gauze mask can block most gas, cause the user to feel difficult to exhale and inhale under the condition of wearing the gauze mask.
However, in order to improve the disadvantage that the user feels difficult to exhale and inhale when wearing the mask, there is a conventional three-dimensional mask 1 equipped with a piston valve 11, as shown in fig. 1A, the conventional three-dimensional mask 1 has a three-dimensional mask body 10 and a piston valve 11, the three-dimensional mask body 10 is used for covering the nose and mouth of the user and is made of a breathable material, the three-dimensional mask body 10 penetrates through a pair of openings 101 located at the nose and mouth of the user, the piston valve 11 is installed around the openings 101 and is provided with a shifting piece 111 (shown in fig. 1B) having a larger contour than the openings 101, and the shifting piece 111 is located outside the three-dimensional mask body 10 and can selectively cover the openings 101.
Referring to fig. 1B, when the conventional three-dimensional mask 1 is applied specifically, the three-dimensional mask body 10 is worn on the nose and mouth of a user, the piston valve 11 is located at one side of the nose and mouth of the user, when the user exhales, the gas in the mouth of the user can push the pull tab 111 away from the opening 101 of the three-dimensional mask body 10, and the pull tab 111 does not completely cover the opening 101, so that most of the gas in the mouth of the user can be exhausted from the opening 101 to the external space, and the user can easily exhale when wearing the conventional three-dimensional mask 1, however, when the user inhales, the gas in the external space can push the pull tab 111 close to the opening 101, so that the pull tab 111 completely covers the opening 101, and the gas in the external space cannot flow into the mouth of the user from the opening 101, and the gas in the external space can only flow into the mouth of the user through the three-dimensional mask body 10, further, when the user wears the conventional stereoscopic mask 1, only a small amount of gas is sucked, and the user feels that it is difficult to inhale the gas, so that the user must increase the number of times of inhaling the gas to obtain a desired amount of gas.
