The components of the human body in the exhaled air comprise water vapor, carbon dioxide, nitrogen, oxygen and the like, and the color change component can obviously change color after contacting any one or more of the water vapor, the carbon dioxide and the oxygen.
Example 2, as shown in fig. 1, a schematic structural diagram of a first structure of a mask capable of displaying a usage duration; FIG. 2 is a schematic view of a first mask structure covering a release paper for showing a period of time; fig. 3 shows a schematic view of the combination of the exhalation check valve 2 and the color changing member 3 of the mask, which can show the length of time of use.
On the basis of the above embodiment, further, the exhalation check valve 2 includes a valve seat 21, a flexible sheet 22 and a valve cover 23. The valve seat 21 is connected on the mask body 1, the valve cover 23 is connected on the valve seat 21, and the flexible sheet is arranged in a cavity formed by enclosing the valve seat 21 and the valve cover 23. When a user inhales, the flexible sheet 22 covers the valve seat 21 and covers the air holes on the valve seat 21, so that the inlet air can only enter after being filtered by the mask body 1; when the user exhales, the gas blows up the flexible sheet 22 through the air hole, and then the gas flows out through the valve cover 23. The color-changing component 3 is arranged on the valve cover 23 or on the mask body 1 close to the valve cover 23, so that the exhaled air basically passes through the color-changing component 3 when flowing out, and the components such as water, carbon dioxide and the like in the exhaled air are gradually accumulated and react with the color-changing component 3 to gradually change the color of the color-changing component 3. The exhalation valve is basically the only passage of the exhaled air, and the exhaled air volume is stable, so that the color-changing component 3 is arranged on the valve cover 23 or on the mask body 1 close to the valve cover 23, the color-changing time of the color-changing component 3 is stable, and the color-changing component is not easily influenced by other factors.
Example 3, as shown in fig. 1, a schematic structural diagram of a first structure of a mask capable of displaying a usage duration; FIG. 2 is a schematic view of a first mask structure covering a release paper for showing a period of time; fig. 3 shows a schematic view of the combination of the exhalation check valve 2 and the color changing member 3 of the mask, which can show the length of time of use.
In addition to the above embodiment, the valve cover 23 is provided with the through groove 231, and the color changing member 3 is connected to the valve cover 23 to cover the through groove 231. So that the color changing member 3 is sufficiently contacted with the exhaled breath.
Further, a plurality of grid bars are arranged on the valve cover 23, the through groove 231 is formed between two adjacent grid bars, and the color-changing component 3 is adhered to the grid bars. The color-changing component 3 is bonded on one side of the grid strips close to the flexible sheet 22, and the grid strips can protect the color-changing component 3, are stably connected and are not easy to fall off; or the color-changing component 3 is bonded on one side of the grid strip far away from the flexible sheet 22, so that the connection is convenient, and a protection device of the color-changing component 3 is also convenient to arrange.
Further, a nose bridge strip 5 is arranged on the mask body 1, and the color-changing part 3 is connected to one side, far away from the nose bridge strip 5, of the valve cover 23. The drop of water after vapor condenses can flow downwards because of gravity, sets up the position that leans on after wearing with color-changing component 3, changes and receives more water, and the color development is more obvious.
Example 4, as shown in fig. 2, the first structure of the mask capable of displaying a long period of use is covered with a release paper.
On the basis of the above embodiment, further, the valve cover 23 is detachably connected to the valve seat 21, and the sealing and peeling paper 4 is connected to both sides of the valve cover 23. The sealing and peeling paper 4 covers both sides of the valve cover 23 in an initial state to cover the color changing member 3, thereby preventing the color changing member 3 from being contaminated and discolored when not in use.
Example 5, as shown in fig. 2, the first structure of the mask capable of displaying the using time period is covered with the release paper.
On the basis of embodiments 1 to 3, further, a first sealing release paper 4 is connected to the valve cover 23, and a second sealing release paper is connected to a surface of the mask body 1 away from the valve cover 23, and covers the valve seat 21. Set up sealed release paper 4 in expiration check valve 2 inside and outside both sides, with the cladding of color-changing component 3, prevent that color-changing component 3 from being contaminated when not using, and relative embodiment 2, the second sealed release paper in this embodiment is changeed and is peeled off, need not unpack valve gap 23.
Example 6, fig. 4 is a schematic structural view of a second structure of a mask capable of displaying a usage period.
On the basis of the embodiment 1-2, further, the valve cover 23 includes a bottom wall and a peripheral side wall connected to the bottom wall, the peripheral side wall is provided with the through groove 231, and the color-changing member 3 is arranged on the mask body 1 and circumferentially arranged around the valve cover 23. This gauze mask is given vent to anger by 2 a week of expiration check valves, and it is more even to give vent to anger, and the gas of exhaling can fully contact with the color-changing component who encircles the setting.
Further, the mask body 1 is connected with a sealing and peeling paper covering the color changing member 3. The color changing member 3 is covered to prevent the color changing member 3 from being contaminated when not in use.
Example 7
In addition to the above embodiments, the color changing member 3 may be any one of a PH test paper, a hygroscopic color changing strip, a litmus test paper, and a ferrous carbonate test paper. When the color-changing part 3 is a PH test paper or litmus test paper, water vapor and carbon dioxide in the gas exhaled by the human body form an acidic solution, so that the PH test paper or litmus test paper changes color. When the color changing component 3 is the ferrous carbonate test paper, the ferrous carbonate test paper is white, the ferrous carbonate test paper gradually changes from white to brown under the action of moisture exhaled by a user and oxygen in the air after the mask is worn, and the wearer can judge whether to change the mask according to the color changing depth and the color changing range.
It should be noted that the embodiments of the present invention and the features and technical solutions thereof may be combined with each other without conflict.
The above embodiments are only used for illustrating the utility model and not for limiting the technical solutions described in the utility model, and although the present invention has been described in detail in the present specification with reference to the above embodiments, the present invention is not limited to the above embodiments, and therefore, any modification or equivalent replacement of the present invention is made; all the technical solutions and modifications without departing from the spirit and scope of the present invention are within the scope of the claims of the present invention.
