The wall thickness that tank body can be reduced accordingly, to mitigate weight, also reside in transport and storage prevents its deformation in the process, ensures good
Air-tightness.
In the preferred scheme, the connector is external screw thread or buckle.It is simple in structure, it is easy to connect, it is convenient for and band
The mask or powered supplied air device of internal thread connect, and using mutual rotatable engagement, installation, convenient disassembly are quick, improve the peace of protection
Overall coefficient.
A kind of lower resistance through type canister, it includes tank body, filter layer and protective cover, passes through the tank mouth setting in tank body
The screw thread of movable connection or the connector of fastening structure pass through tank wall directly with mask or powered supplied air device unicom
Reinforcing rib and protective cover prevent from causing tank body to deform in transportational process or during storage, protective cover and rubber stopper fitted seal tank
Body prevents internal filter layer rotten, shelf-life and service life is improved, in use, filtered air is directly entered mask
Or powered supplied air device.The present invention overcomes former arc canisters to use reducing connection structure, and the big operation of volume is inconvenient, resistance
Greatly, the problem of unsmooth breath, have it is simple in structure, canister directly with mask or powered supplied air device unicom, increase air inlet cut
Face area, respiratory resistance smaller improve breathing comfort, convenient and fast connection, occupy little space, operation more easily feature.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the structural schematic diagram of tank body of the present invention.
Fig. 3 is the structural schematic diagram of protective cover of the present invention.
In figure：Tank body 1, air inlet 11, connector 12, reinforcing rib 13, filter layer 2, protective cover 3, interface 31.
Specific implementation mode
In Fig. 1 ~ Fig. 3, a kind of lower resistance through type canister, it includes tank body 1, filter layer 2 and protective cover 3；It is described
Tank body 1 be hollow tube structure, bottom be equipped with evagination air inlet 11, nozzle be equipped with connector 12, cylinder body outer wall is equipped with
Reinforcing rib 13；The protective cover 3 is cylinder trench structure, and groove body inner wall is equipped with interface 31；Filter layer 2 is located at tank body 1
In cavity, the interface 31 of protective cover 3 coordinates with the connector 12 of tank body 1.It is simple in structure, it can by the tank mouth setting in tank body 1
The screw thread of flexible connection or the connector 12 of fastening structure increase air inlet section directly with mask or powered supplied air device unicom
Area prevents from causing tank body 1 to deform in transportational process or during storage by the reinforcing rib 13 and protective cover 3 of 1 outer wall of tank body,
Protective cover 3 and rubber stopper fitted seal tank body 1 prevent internal filter layer 2 rotten, improve shelf-life and service life, use
When, filtered air is directly entered mask or powered supplied air device, is connect without the air-flow variable-diameter structure and minor diameter of diminution
Mouth connection, respiratory resistance smaller improve breathing comfort, convenient and fast connection, occupy little space, operation is more convenient.
In the preferred scheme, the tank body 1 outlet is and the prismatic structure of tank body.It is straight by filtered air
It taps into mask or powered supplied air device, increases intake area, without the air-flow variable-diameter structure and minor diameter of diminution
Interface connects, respiratory resistance smaller, improves breathing comfort.
In preferred scheme, the reinforcing rib 13 is the loop configuration along 1 evagination of tank body.The structure for increasing tank body 1 is strong
Degree, can reduce the wall thickness of tank body 1 accordingly, and to mitigate weight, also reside in transport and storage prevents its deformation in the process, ensures
Good air-tightness.
