For solving the problems of the technologies described above, the utility model adopts following technical scheme: the anti-haze mouth mask of electrostatic precipitation with whistle, comprise headband, described headband front end is provided with breathes sealing face shield, headband left side and right side are respectively equipped with a high voltage electrostatic filter, breathing sealing face shield front side is provided with and the three-way pipe of breathing sealing face shield internal communication, three ports of three-way pipe are respectively towards a left side, towards right and setting down, the left port of three-way pipe is connected with the high voltage electrostatic filter in left side and the high voltage electrostatic filter on right side by air induction hose respectively with right output port, between three-way pipe rear side and breathing sealing face shield front side, be provided with the air-breathing check-valves of diaphragm type, breathe sealing bottom, face shield front side and be provided with pattern switching valve, the import of pattern switching valve is connected with the lower port of three-way pipe, pattern switching valve has two gas outlets, the gas outlet place of pattern switching valve is provided with diaphragm type expiration check-valves, and another gas outlet of pattern switching valve is connected with a whistle.
Described high voltage electrostatic filter comprises seal casinghousing and dc source, seal casinghousing is connected on headband, dc source arranges seal casinghousing end face rear portion, seal casinghousing front end is connected with air induction hose, in seal casinghousing, be provided with the positive plate and the negative plate that arrange along fore-and-aft direction, between positive plate and negative plate, form zigzag current path, seal casinghousing rear end is provided with bulky grain thing and crosses filter core, and seal casinghousing end face front portion is provided with battery capacity indication lamp.
Adopt technique scheme, pattern switching valve adopts rotation mode switch mode, and pattern switching valve is breathed the sealing valve gap of face shield front side and the valve body of rotation forms by being fixed on, on valve gap and valve body all to there being two openings.In the time of 90 ° of rotary valves, can select to seal expiratory airflow and forced draft discharges from whistle, or select directly to discharge by diaphragm type expiration check-valves from opening.By mode transitions valve, can switch and whether use whistle, there is traffic police and the traffic management assistant that the mouth mask of this architectural feature is applicable to direct traffic in city and wear.
The utility model replaces the cotton filter of traditional static dirt structure with high voltage electrostatic filter.The air-breathing check-valves of diaphragm type expiration check-valves and diaphragm type can ensure that humid air can not be back to high voltage electrostatic filter and cause short circuit.
In high voltage electrostatic filter, be provided with positive plate and negative plate, can allow like this and contact with negative plate with positive plate more fully by way of air, zigzag current path can improve pick-up performance.Bulky grain thing cross filter core be used for preventing stop up and short circuit positive plate and negative plate, this bulky grain thing cross filter core be can clean rear reusable.Positive plate and negative plate also can split out cleaning after being stopped up by dust.Therefore the member in the utility model does not have easily-consumed products.
Main design thought of the present utility model is exactly by using high voltage electrostatic filter to complete the removal to micronic dust, and there is no the use of easily-consumed products, is more suitable for like this worker of these class Long contact time pollution sources (haze etc.) of city management person.Can install the expiration whistle that can switch by pattern additional meets this class of city management person and contact stain source and has again the personnel of these class signaling device needs of pair whistle simultaneously.
The utility model is simple in structure, reasonable in design, and dedusting, anti-haze are effective, can meet the demand of long-time use.Also solved the demand to whistle while wearing mouth mask such as the city such as traffic police, traffic management assistant special population simultaneously.
