Abstract
The invention discloses a mask with multiple filtering layers. The mask comprises a mask body and filtering mask bodies, wherein two ends of the mask body are provided with ear-hook strips; a vent hole is formed in the center of the mask body; the inner side end of the vent hole is provided with an annular gasket frame connected and fixed together with the filtering mask bodies; filter screens are arranged in the filtering mask bodies; the annular gasket frame is provided with the plurality of the filtering mask bodies; the outer side wall of the mask body at one end of each filtering mask body is provided with an external thread, the inner side wall of the mask body at the other end of each filtering mask body is provided with an internal thread; and the filtering mask bodies are in threaded and rotary connection with each other. In such a way, the filtering mask bodies with corresponding thicknesses can be selected to be overlapped and used according to the using environment of the mask, the more the mounted filtering mask bodies are, the better the corresponding filtering performance is, and the filtering mask bodies are connected in a threaded dismountable way, so that the filtering mask bodies are convenient and rapid in mounting and dismounting, and the mask is convenient to use.
Description
Technical field
The present invention relates to mouth mask field, particularly relate to a kind of multi-filtering layer mouth mask.
Background technology
Mouth mask is a kind of sanitary product, refers generally to be worn over nose and mouth for filtering the air of admission port nose, to reach the apparatus of the gas of blocking harmful, smell, spittle turnover wearer's mouth nose, makes with gauze or paper etc. The air entering lung is had certain filteration by mouth mask, when respiratory infectious disease is popular, in the environment that dust etc. pollutes during operation, wears masks and has extraordinary effect. But traditional mouth mask is all one-body molded, does not possess the function carrying out selective filter use according to environmental pollution degree, parts can not be dismantled and carry out cleaning or changing, reduce the work-ing life of mouth mask.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of multi-filtering layer mouth mask, it is possible to selects the filtration cover body superposition of respective thickness to use according to mouth mask environment for use, installs more many corresponding filterablenesses of filtration cover body more good.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of multi-filtering layer mouth mask, comprise mask body and filter cover body, described mask body two ends are provided with ear and hook band, described mask body central authorities have offered a ventilation mouth, inside described ventilation mouth, end is provided with ring gasket horse, described ring gasket horse and described filtration cover body are connected and fixed, it is provided with filtering net in described filtration cover body, described ring gasket horse is provided with multiple described filtration cover body, described filtration cover body one end cover body outer side wall is provided with outside screw, described filtration cover body the other end cover body inner side-wall is provided with internal thread, the described mutual screw thread of filtration cover body spins.
In a preferred embodiment of the present invention, described ring gasket horse outside is provided with outside screw, and described filtration cover body is provided with the internal thread described ring gasket horse outside that is threaded by cover body inner side-wall and is provided with outside screw and be fixed in described mask body.
In a preferred embodiment of the present invention, described filtration cover body is provided with internal thread by inner side-wall and is threaded on cover body outer side wall outside screw and is interconnected and fixed.
In a preferred embodiment of the present invention, the filtration mesh number on the described filtration cover body of described mask body end is greater than away from the filtration mesh number on the described filtration cover body of described mask body end.
In a preferred embodiment of the present invention, described filtration cover body is cylinder type cover body.
The invention has the beneficial effects as follows: the present invention can select the filtration cover body superposition of respective thickness to use according to mouth mask environment for use, more many corresponding filterablenesses of filtration cover body are installed more good, filtering the mutual screw thread detachable of cover body to connect, it is all fast convenient to mount and dismount, it may also be useful to convenient.
