The protective mask comprises a mask part; a filtering part for increasing the filtering area is also connected with the mask part; the filtering part can be connected with a windpipe or be detachably clamped with the mask part or the windpipe; the filtering part comprises at least two filtering bodies nested from inner to outer; and furthermore, the filtering part can be in the shape of a cylinder, a can or a box, or in other suitable shapes. The protective mask can greatly increase the filtering area of a filtering device on the protective mask body to 600 to 1200cm <2> or more, which is 3 to 10 times of the public known filtering area of a disposable mask, so that the protective mask has little breathing resistance when in use and has a good protective performance, and a user can breath comfortably while wearing the protective mask; and the protective mask thoroughly solves the major problem that nobody is willing to wear the mask because the user is short of breath while wearing a mask.
Description
Technical field
The utility model relates to protection mouth mask technical field.
Background technology
A kind of important occupational safety and health product of protective mask, along with the deterioration of natural environment, the increasing of the great public health event that happens suddenly, the importance of protective articles such as mouth mask highlights.At present, disposable breathing articles for use market, the middle and high end of China is all occupied by the product of the international business of world developed country, as protection series products of the Protection Product of Minnesota Mining and Manufacturing Company, French Ba Gu company etc.
For protective mask, under the identical condition of the filter efficiency of its unit are filtering material, it is more little to filter the gross area, and respiratory resistance is big more, and the user will feel to breathe and feel bad more; And it is big more to filter the gross area, and inspiratory resistance is more little, and the gas communication amount is big more, and the user will feel to breathe comfortable more.The general filter area of existing disposable breathing mask mostly is 100CM
2About, maximum is no more than 200CM
2, under this filtering material area condition less than normal, if require the filter efficiency height, respiratory resistance is just big; Otherwise then protective action will variation.This is the subject matter that current protective mask exists.
Industry is for improving " filter efficiency; reduce respiratory resistance " of product in recent years, some improvement have been made technically, but mainly be confined to the exploitation of mouth mask new material, although occurred reducing the electronic gauze mask of respiratory resistance on the market,, improve the barrier propterty of disposable breathing mask articles for use with electronic technology, technology is immature, and cost is too high, unrealistic.
The utility model content
It is big that technical problem to be solved in the utility model provides a kind of filter area, and respiratory resistance is little, filter efficiency is high and use comfortable disposable breathing mask.
For solving the problems of the technologies described above, a kind of technical scheme of realization of the present utility model is:
Design a kind of protective mask, include mouth mask portion, also be connected with the filter house that is used to increase filter area in the mouth mask portion.
In order further to increase filter area, also be connected with tracheae between mouth mask portion and the filter house.Described filter house can be cylindrical body or tank-like body or box body, and filter house removably is connected on mouth mask portion or the tracheae.
Filter house in the technique scheme is made of nested inside and outside two filtering bodies at least, first filtering bodies is made up of outermost filter course and second filter course adjacent with outermost filter course inwall, the outermost filter course is connected with the second filter course two ends, space hollow between the outermost filter course and second filter course forms first hollow space, this first hollow space is communicated with tracheae or mouth mask portion, air is by outermost filter course outer wall, second filter course inner face or first the filtering bodies two ends adjacent with outermost filter course inwall enter this first hollow space after filtering, enter mouth mask portion more thus or are transported to mouth mask portion through tracheae;
Second filtering bodies is nested in first filtering bodies, link into an integrated entity by stake body between two filtering bodies, space between two filtering bodies is the air flue that is communicated with outside air, second filtering bodies is made up of the 3rd filter course and the 4th filter course adjacent with the 3rd filter course inwall, the space that the 4th filter course inwall forms also is the outside air flue that is communicated with outside air, the 3rd filter course is connected with the 4th filter course two ends, space hollow between the 3rd filter course and the 4th filter course forms second hollow space, this second hollow space is communicated with tracheae or mouth mask portion, outside air in the air flue is by the 3rd filter course outside, the 4th filter course inner face or second filtering bodies two ends enter this second hollow space after filtering, enter mouth mask portion more thus or are transported to mouth mask portion through tracheae.
For the waste gas that prevents to breathe out enters in the protective mask once more, on described mouth mask portion or tracheae or filter house, be provided with breather cheek valve, or one-way exhaust valve is set, the intake and exhaust switch also is installed on described breather cheek valve or one-way exhaust valve.
Fixing during for the ease of use also is provided with bandage on protective mask.
The utility model has following remarkable result compared to existing technology;
The utility model increases filter house and the tracheae with large tracts of land filtering bodies on the basis of existing mouth mask body, make the filter area of whole protection mouth mask increase to 600-1200 CM
2Or more, be known disposable breathing mask 3-10 doubly, this protective mask respiratory resistance is little, breathes comfortable, easy to use.
This protective mask has solved existing protective mask, the filter efficiency height, respiratory resistance is big, or respiratory resistance is low, and filter efficiency is then low, the significant problem of barrier propterty difference, this protective mask can be so that the user uses more comfortable, can solve the significant problem of " because wear masks and feel suffocated, and the no one is ready to use mouth mask ", this protective mask is a kind of occupational safety and health Protection Product of hommization more.
