Description
Technical field
The utility model relates to protector field, particularly a kind of safety cap of dust proof and gas defence.
Background technology
Inconvenience when commercially available various anti-dust respirator is worn, the situation that the secondary that easily occurs giving off carbon dioxide when breathing sucks, thus human body oxygen absorbed is brought uncomfortable.The commercially available filtering surface protecting dirt mouth mask is little, and filter effect is undesirable, and dust proof rate is low, and have the working region of the smog of higher concentration at some, mouth mask very easily loses dust-proof effect.
Simultaneously, the skin of traditional anti-dust respirator often gathers the dirt such as dust, bacterium in a lot of outside air, and nexine blocks bacterium, the saliva of exhalation, therefore, some bad impacts are also existed on user, and, when wearing, along with the change of working time, respiratory resistance becomes large, also can affect the filter effect of anti-dust respirator.
In addition, commercially available function singleness of protecting dirt mouth mask, only there is dust-proof effect, can limitation be there is when some special industries use, as military police time, not only need anti-dust respirator, also need effectively to protect head, current equipment is generally that head-shield is separated with mouth mask, so just causes protective cover to wear reaction slowly, affects activity.
Utility model content
The purpose of this utility model is to provide a kind of protector, a kind of safety cap being integrated with dust proof and gas defence, this safety cap is to the innovation of traditional mouth mask weak point, solve and wear inconvenience, function singleness, the secondary that gives off carbon dioxide during breathing sucks, and it is slow that reaction worn by military police protective cover, affect activity, the shortcoming of function singleness.
To achieve these goals, the utility model have employed following technical scheme:
A safety cap for dust proof and gas defence, comprises safety cap body, respirator and eyeshade, and described eyeshade is connected by the lower edge of elastic cord with described safety cap body;
Described safety cap body comprises outer cap housing, the first filter course, the first gas passage and interior cap from outside to inside successively, the two ends of described outer cap housing are provided with the air inlet of band valve, described first filter course is engraved structure, and in be provided with filtering material, described first filter course is connected with described first gas passage, the two ends of described first gas passage are provided with the gas outlet of band valve, and described gas outlet is provided with tracheae and is communicated with described respirator, and described respirator is provided with a unidirectional air outlet valve.
Preferably, described respirator comprises all-in-one-piece nose cup and mouth mask, and the edge of described respirator is that soft rubber is made, and the lower end of described respirator is provided with described unidirectional air outlet valve.
As another kind of technical scheme, described respirator comprises the nose cup linked into an integrated entity with described eyeshade, and the edge of described nose cup is that soft rubber is made, and the lower end of described nose cup is provided with described unidirectional air outlet valve.
Further, the second filter course, the second gas passage is provided with successively between first gas passage and described interior cap, described second filter course is engraved structure, and in be provided with filtering material, the two ends of the second gas passage are provided with the second gas outlet of band valve, and this second gas outlet and described tracheae adaptation.
Further, the filtering material in described first filter course or the second filter course is multi-layer nonwoven fabrics or active carbon cloth.
Further, being connected with being screwed between described interior cap of described outer cap housing.
As another kind of technical scheme, described air inlet is provided with a filter cartridge coordinated with described air inlet, is provided with filtering material in described filter cartridge, and this filtering material is multi-layer nonwoven fabrics or active carbon cloth or arranges material voluntarily according to the different material of reply.
The utility model tool has the following advantages:
1, by antidusting and anti-poisoning mask eyeshade and safety cap being integrated in one, go for numerous different occasion, and omnibearing protection can be provided to user;
2, filter course can be changed, and optionally changes different filter courses according to during the pernicious gas that reply is different;
3, filter course is integrated in safety cap, the burden of user can be reduced;
4, the area due to the traditional mouth mask of the surface area ratio of safety cap is large, thus filtering surface is large, and filter effect is strong, and dust proof rate is high;
5, safety cap is by arranging unidirectional air outlet valve, effectively can avoid the secondary suction that gives off carbon dioxide when breathing, dramatically reduce the sense of discomfort of user;
6, dress easy to use, do not need use eyeshade time, can directly eyeshade be placed on safety cap body, especially at military police reply emergency case quick donning mouth mask eyeshade.
