Referring to fig. 1 and 3, in an embodiment of the present invention, a mask is provided, including a mask body 10 and an elastic connection portion 20 connected to the mask body 10, the elastic connection portion 20 is used for cooperating with a wearer's head to fix the mask body 10, the mask body 10 includes a filter portion 11, a light transmission portion 12 and a support portion 14 capable of transmitting visible light, the filter portion 11 is connected to the light transmission portion 12, the support portion 14 is used for forming a cavity 30 corresponding to a mouth position on the mask body 10, the filter portion 11 is used for filtering air entering the cavity 30, a portion of a side wall of the cavity 30 is formed by all or a part of the filter portion 11, another portion is formed by all or a part of the light transmission portion 12, when the mask body 10 is fixed to the head, the light transmission portion 12 is used for identifying a movement of the mouth from an outer side of the cavity 30. In the following exemplary embodiments, the present invention is illustrated by providing only a limited example, but should not be construed as limiting the present invention.

As shown in fig. 1 and 3, the mask body 10 is fixed to the head of the wearer by the elastic connection portion 20, so that the mask body 10 can be fixed to the vicinity of the mouth position of the wearer, the elastic connection portion 20 may be a string, a hanging loop, or the like having elasticity, and is hooked to the back of the head or the ear portion by elastic deformation, the support portion 14 is used to form a cavity 30 corresponding to the mouth position on the mask body 10, the support portion 14 may be formed by a rigid sheet, a bracket, or the like, so that the cavity 30 having a specific volume can be formed on the mask body 10, and the shape of the cavity 30 is not particularly limited. The filter part 11 is capable of forming a cavity 30 for filtered air to enter, where the cavity 30 may be open to the atmosphere, and due to the cavity 30, it may partially block the unfiltered air from directly passing into the nasal cavity or mouth of the wearer, thereby protecting the respiratory tract. Moreover, the cavity 30 may be used to form a space for the wearer to move and give way to the mouth, so that the mask body 10 is not pressed against the mouth completely, the wearer does not need to create the space for the mouth to move only by elastic adjustment, and the size of the cavity 30 is not limited herein.

In this embodiment, the filter portion 11 is connected to the light-transmitting portion 12, and the connection may be fixed connection or movable connection, for example, the filter portion 11 may be connected by sewing so that the filter portion 11 is movable with respect to the light-transmitting portion 12, and the filter portion 11 may be fixed to one side of the light-transmitting portion 12 by bonding. The filter part 11 is mainly used for filtering impurities in the air, such as dust, bacteria or viruses, so that the filtered air enters the cavity 30. The filter portion 11 may be formed of a cloth layer of a known material or the like. A portion of the sidewall of the cavity 30 is formed by all or a portion of the filter portion 11, and another portion of the sidewall of the cavity 30 is formed by all or a portion of the light-transmitting portion 12, so that the cavity 30 can be filled with the air filtered by the filter portion 11 smoothly, and the space inside the cavity 30 can be visible through the light-transmitting portion 12, where the light-transmitting portion 12 may be a transparent member made of a known material, and the transparent member may have a certain stiffness or may not have a good stiffness, and it should be described in detail that since the cavity 30 may have a specific volume, even though the light-transmitting portion 12 has flexibility, for example: plastic film or thin sheet, etc., can also achieve the purpose of the utility model. When a part of the sidewall of the cavity 30 is constituted by the filter portion 11 or the light-transmitting portion 12, a shape of an open cavity surrounded by the filter portion 11 and the light-transmitting portion 12 may be provided so as to be fitted near the mouth position through the open side of the open cavity; when a part of the sidewall of the chamber 30 is constituted by the filter portion 11 or the light transmitting portion 12, the mask body 10 may be supported by the support portion 14 to form the chamber 30. Of course, it is also possible that a part of the filter layer portion 11 and the light-transmitting portion 12 is outside the sidewall of the cavity 30 to provide a larger face visualization area, which will not be described in detail herein. The light-transmitting part 12 can transmit visible light, the visible light is light waves with wavelengths in the region between ultraviolet light and infrared light bands, so that the expression and the action of the mouth of a mask wearer can be observed directly by naked eyes, and when the mask body 10 is fixed on the head, the light-transmitting part 12 is used for identifying the action of the mouth from the outer side of the cavity 30, such as: can show smile when wearing, increase the sense of familiarity, promote the service impression etc. and improve the visual degree of gauze mask.

Alternatively, the supporting portion 14 is used to connect the mask body 10 and the side wall of the cavity 30, and the supporting portion 14 may have a certain stiffness to form a flexible hinge portion between the mask body 10 and the side wall, so that the side cavity 30 has a storage state of being folded into the mask body 10 and a wearing state of being extended to form a larger volume, which will not be described in detail herein.

Referring to fig. 2 and 4, in view of convenience of production, it is preferable that the mask includes a rigid transparent sheet 120 for forming the support portion 14 and the light transmission portion 12, a part of the sidewall is formed by the entire light transmission portion 12, and the filter portion 11 includes a first filter layer 111 joined to an edge of one side of the rigid transparent sheet 120 and surrounding the rigid transparent sheet 120. Since the transparent rigid sheet 120 not only transmits visible light, but also has good stiffness, the first gap V1 formed by full contact with human skin is avoided. The rigid transparent sheet 120 may be used to support the first filter layer 111, and to form a second gap V2 by standing the first filter layer 111 at a certain height from the skin of a person. The first gap V1 and the second gap V2 form a space for the wearer to move and give way to the mouth, so that the mask body 10 is not completely pressed against the mouth, and the situation that the mouth moves only through elastic adjustment is avoided. The first filter layer 111 may be made of a relatively air-permeable material such as meltblown fabric, non-woven fabric, etc. to facilitate smooth breathing of the wearer, and the rigid transparent sheet 120 is made of a known transparent plastic or resin material, such as: the PC or ABS member may also be made of a known fiber material, such as a transparent member with a certain stiffness like glass.
