Battery equipped with mobile charging, battery connect control switch；The downside of head-shield ontology be equipped with collapsible sheath, sheath with make
User's neck is tightly connected by retraction cord.
Preferably, the filter cartridge is connect with head-shield ontology transverse direction drawing out type, and head-shield ontology is equipped with inserting for transverse opening
Slot, filter cartridge and slot are laterally extracted and are fixed.
Preferably, U-lag is equipped on the outside of the battery case, battery is equipped with nut, and nut and U-lag cooperation are realized and compressed
Connection.
Preferably, the bluff piece can be started with head-shield ontology and be connect, and bluff piece rear is equipped with sealing joint strip.
Further, sealing strip is equipped between the filter cartridge and slot.
The utility model is beneficial in that, can be administered operation in high concentration and be used, outside air is filtered
It is sent into head-shield afterwards, exhaust gas is discharged, breathe the smooth comfort level and protective for improving user, the electricity of external mobile charging
Pond provides good charging convenience for device.
Detailed description of the invention
The structural schematic diagram of Fig. 1 the utility model；
1. bluff piece in figure, 2. fans, 21. filter cartridges, 22. heating nets, 3. battery cases, 4. exhaust fans, 5. retraction cords.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, the utility model provides a kind of application operation protective device, including can be by user head entirety
The front side of the enclosed head-shield ontology of cladding, head-shield ontology is equipped with bluff piece 1, and the material of bluff piece is made of transparent plastic, is used for
Observe external circumstances.Bluff piece, which can be, to be fixed on head-shield ontology, also can be made raising type design, such rear needs to install additional
Sealing joint strip improves leakproofness.
It is equipped with below the front side of head-shield ontology in connection head-shield and extraneous air intake passage, the outermost of air intake passage
Equipped with filter cartridge 21, filter core is equipped in filter cartridge, using the filter element that may filter that poisonous gas, the rear of filter cartridge is set filter core
The fan 2 of oriented interior air-breathing, from it is existing to need human body actively to breathe air inlet different, fan 2 can replace human body air-breathing, and wind be drawn
Enter, and is sucked into head-shield ontology after being filtered by filter cartridge.The exhaust fan be vented outwards is equipped with below the rear side of head-shield ontology
4, for the intrinsic exhaust gas of head-shield to be discharged.In order to further enhance obturation effect, the downside of head-shield ontology is equipped with can
The sheath of tightening, sheath are tightly connected with user's neck by retraction cord 5.It will be external empty this makes it possible to form front fan
Gas introduces the structure internal, the exhaust gas of personnel's exhalation is discharged by rear exhaust fan after filtering, guarantee that personnel breathe to clean
Air.
As the power pack of whole device, the side of head-shield ontology is equipped with the battery case 6 of opening upwards, inside battery case
