[0058] Please also refer to Figures 2 to 5 , as shown in the drawings referred to in the left column, the mask 1 of this embodiment can add liquid 132 and has a mask body 11 , an attached airway structure 12 , a hydrophilic foam 13 and a breathable cover 14 . The mask body 11 is bent to form an inner air chamber 16 of the mask, and the inner air chamber 16 of the mask can directly face the mouth and nose of the wearer to provide breathing. The mask body 11 can be selected to be made of an airtight material, thereby preventing the dust particles 3 from directly passing through the mask body 11 and entering the air chamber 16 in the mouth mask, and preventing the dust particles 3 from being sucked into the respiratory system of the wearer 2 and affecting health. Furthermore, the mask body 11 can also be selected to be made of elastic materials such as elastic colloid, so that the mask body 11 can be closely fitted to the face of the wearer 2 through elastic deformation, so that...

[0066] Please also refer to Figures 6 to 8-3 , as shown in the drawings referred to in the left column, both the second embodiment and the first embodiment have a mask body 11 and a hydrophilic foam 13, wherein the biggest difference between the second embodiment and the first embodiment lies in the first In the second embodiment, the attached airway structure is omitted. In addition, in the second embodiment, the mouth mask body 11 also has a partition 15, the partition 15 separates the face of the wearer 2 from the hydrophilic foam 13, and the partition 15 can be selected as a waterproof material, so , the moisture of the hydrophilic foam 13 after absorbing water is not easy to penetrate the isolation part 15, and the wearer 2 feels uncomfortable when the isolation part 15 is damp, that is, when the face of the wearer 2 touches the isolation part 15 , and will not feel the wet isolation portion 15, so that the wearer 2 feels comfortable.

Abstract

The invention provides a mask capable of being equipped with liquid to filter dust particles. The mask is at least composed of a mask body, an attached air channel structure and a hydrophilic foamingbody. The mask body can be elastically deformed to be attached to the face of a wearer, and breathing airflow generated when the wearer inhales enters an air chamber in the mask only through the attached air channel structure. With the hydrophilic foaming body, absorbed liquid can adsorb dust particles in the breathing airflow so as to filter the dust particles in the breathing airflow and clean the breathing airflow, and a clean breathing environment is provided for a wearer so as to protect the health of the wearer. Besides, the breathing airflow can travel on the attached air passage structure under the condition that the attached air passage structure is hardly subjected to resistance through the breathable passage penetrating through the hydrophilic foaming body, so that the wearer can breathe smoothly, the discomfort is reduced, and the problem that the wearer is difficult to breathe due to the use of a known high-density mask is solved.

Description

technical field [0001] The invention relates to a mask, in particular to a mask capable of filtering dust particles entrained by a wearer's breathing airflow. Background technique [0002] Masks on the market have different filtering effects due to different materials. Such as figure 1 As shown, gauze masks and surgical masks have poor filtering effects and cannot effectively fit the wearer's face, so that dust particles 3 in the wearer's breathing airflow can easily enter the gap between the mask and the wearer's face 4 And let the wearer inhale. In this regard, some people use N95 masks that can fit the wearer's face to block the dust particles in the external environment. However, the N95 respirator is made of high-density material with poor air permeability, thereby blocking the passage of dust particles 3 in the wearer's breathing airflow to provide filtering for the breathing airflow so that the N95 mask has a good filtering effect, but it is easy to cause the weare...
