The gas mask is simple in structure and convenient to use, can improve the air inflow and increases the efficiency of use of the filter element, so that a user breathes more comfortably.
Description
Technical field
The present invention relates to a kind of protective articles, relate in particular to a kind of breathing mask.
Background technology
Present air pollution is more and more serious, and when the air quality difference, some protective articles play very crucial effect for the position that protection respiratory tract and eyes etc. are in direct contact with in the pollution sources.Goggles can protect eyes not encroached on, and breathing mask can protect respiratory tract and mouth to preserve from.Some special work can require the practitioner to be exposed in the environment of severe contamination, and it is even more important that protective articles just seems.And existing breathing mask mostly has only an air inlet, has both made the filter core of filtered air can not bring into play good effect, and reducing air inflow again, to allow the user breathe comfortable inadequately.The breathing mask that can make full use of filter core and user's comfort level is improved does not also occur.
Summary of the invention
The invention provides a kind of breathing mask, can increase air inflow and improve the service efficiency of filter core.
The present invention is a kind of breathing mask, and is concrete, and described breathing mask comprises cover body, filter core, headband, mouth mask; Wherein, described cover body is that truncated cone-shaped is provided with a plurality of air inlets filter core is in communication with the outside; The bottom surface that described mouth mask is arranged at the truncated cone-shaped cover body is connected with the filter core end, and the headband two ends link to each other with cover body.
Above-mentioned breathing mask, wherein, described air inlet is three, and described cover body upper bottom surface is provided with an air inlet, and the side is provided with two air inlets.
