Detailed Implementation

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0025] This embodiment provides a water-absorbing and anti-fog face mask, such as Figure 1 As shown, the absorbent anti-fog mask includes a mask body 1 and a neckband 2. The mask body 1 includes an air outlet area 11 corresponding to the wearer's mouth and nose, and first air inlets 12 located on the upper and lower sides of the air outlet area 11. The air outlet area 11 is positioned close to the mouth and nose, making it easier for hot water vapor exhaled from the mouth and nose to escape from the air outlet area 11 to the outside of the absorbent anti-fog mask. Gas can more easily enter the headgear from the first air inlets 12, ensuring that the air inhaled by the wearer contains water vapor and improving the wearer's breathing comfort. Preferably, the gas permeability of the first air inlets 12 is greater than that of the air outlet area 11.

[0026] A water-absorbing layer 13 is provided in the air outlet zone 11.

[0027] The water-absorbing anti-fog mask provided by this utility model can absorb water vapor in exhaled air through the setting of water-absorbing layer 13, thereby preventing hot water vapor from forming fog on the lens. It does not require treatment of helmet lenses, has low cost, and can be used in all helmets.

[0028] The material of the absorbent house cover is not specifically limited in this invention; conventional materials in the field, such as elastic fabric, can be used.

[0029] In one embodiment, the mask body 1 is a half mask, and a sealing skirt (not shown) is provided at the top.

[0030] In one embodiment, the water-absorbing and anti-fog mask also includes a head cover 3, which is connected to the mask body 1 and forms an opening 4 in the area corresponding to the wearer's eyes.

[0031] In an embodiment, the headgear 3 and the mask body 1 are integrated.

[0032] In an embodiment, the second air inlet area 14 is arranged on both sides of the air outlet area 11.

[0033] In an embodiment, as shown in FIG. 1, the first air inlet area 12 and the second air inlet area 14 are respectively composed of a first inner side cloth 15, a first gas guiding layer 16 and a first outer side cloth 17 from inside to outside. Figure 2

[0034] In an embodiment, as shown in FIG. 1, the first gas guiding layer 16 includes a first fixed strip 18 and a first movable leaf 19. The first fixed strip 18 is fixed on the first outer side cloth 17 at intervals. One end of the first movable leaf 19 is fixed on the bottom of the first fixed strip 18 and close to the first inner side cloth 15, and the other end is overlapped on the adjacent first fixed strip 18. When the gas needs to pass from the first inner side cloth 15 to the first outer side cloth 17, the first movable leaf 19 is closed, and the gas flux is reduced. When the gas needs to pass from the first outer side cloth 17 to the first inner side cloth 15, the first movable leaf 19 is opened, and the gas flux is increased. Figure 3

[0035] In an embodiment, as shown in FIG. 1, the air outlet area 11 is composed of a second inner side cloth 20, a second gas guiding layer 21, a water absorbing layer 13 and a second outer side cloth 22 from inside to outside.

[0036] In an embodiment, the air outlet area 11 is composed of the second inner side cloth 20, the water absorbing layer 13 and the second outer side cloth 22 from inside to outside.

[0037] In an embodiment, the water absorbing layer 13 is made of high molecular water absorbing resin. The high molecular water absorbing resin has very strong water absorbing capacity, which can absorb water several hundred times or even thousands times of its own weight. The high molecular water absorbing resin has excellent water retaining capacity, and the absorbed water will not be lost even under pressure, ensuring that the mask body remains dry. The high molecular water absorbing resin has good stability to light, heat, acid and alkali, and is harmless to the environment. Preferably, the water absorbing layer 13 is made of acrylic acid-based water absorbing resin.

[0038] In the use of the above-mentioned water absorbing and anti-fog mask, the water absorbing layer 13 in the water absorbing and anti-fog mask can absorb the water vapor in the exhaled gas, thereby preventing the formation of fog on the lens caused by the hot water vapor. The helmet lens does not need to be treated, the cost is low, and it can be applied to all helmets.

[0039] ​​Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
