Description
Technical field
The utility model is related to the modular construction of medical oxygen generator, specifically a kind of oxygenerator inlet air filter system.
Background technology
Existing molecular-sieve type oxygen generator generally include shell and in shell by parts such as compressor, molecular sieves
The oxygen generation system of composition.The air inlet of oxygen generation system is usually the external open air inlet openings by the filter on shell
Direct air inlet.Its defect is:1, the installation cavity of filter opens wide, and not only influences the globality of hull outside, is also easy dust accumulation, no
It is convenient to clean；2, charge air flow is underused, the waste of energy consumption is caused.
Invention content
Technical problem to be solved by the utility model is to provide a kind of physical integrities, and good, cleaning facilitates, can utilize
Charge air flow carries out internal part cooling oxygenerator inlet air filter system.
The oxygenerator inlet air filter system of the utility model includes the internal shell for being mounted with oxygen generation system, under shell
Portion is provided with total air inlet, and the top of shell is arranged filter installation cavity, air intake filter is installed in filter installation cavity；Filter
Installation cavity towards being provided with venthole on the siding of enclosure interior side, venthole by the gap of housing cavity and lower part always into
Gas port communicates；The outlet nozzle of filter is connect by pipeline with internal oxygen generation system.
Further, the filter installation cavity has an opening towards the side of hull outside, it is open by with shell appearance
The equal cover closure in face.
Further, the filter includes：Fixed cover with filter installation cavity inner side wall plate one and fixed cover pair
Filter bowl, the sealing ring between fixed cover and movable guard for closing installation.
Further, the outlet nozzle extends inwardly into housing cavity, and is integrally formed with filter installation cavity inner side wall plate.
Further, total air inlet is in lattice-shaped along the arrangement of housing bottom side.
The utility model has the advantages that：1, filter is by housing cavity air inlet, outside closing, it is therefore prevented that filter installation cavity
Dust accumulation also makes hull outside keep complete plane, improves globality；2, air-flow is reached the process of filter by total air inlet
In, by the gap of housing cavity, the operation heat of the components such as compressor, molecular sieve can be taken away, auxiliary heat dissipation is played
Effect.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model embodiment；
Fig. 2 is the filter-portion sectional view of the utility model embodiment；
Fig. 3 is the filter installation cavity medial surface structural schematic diagram of the utility model embodiment.
Specific implementation mode
As shown in Figure 1, the oxygenerator inlet air filter system includes the internal shell 1 for being mounted with oxygen generation system, shell
Lower part is provided with total air inlet 2, and total air inlet 2 is in lattice-shaped along the arrangement of housing bottom side；The top setting filter of shell is pacified
It behave affectedly 3, the filter 4 of installation air inlet in filter installation cavity；Filter installation cavity is towards opening on the siding of enclosure interior side
There is venthole 5（Referring to Fig. 3）, venthole communicated by the gap of housing cavity with total air inlet 2 of lower part；Such as Fig. 2, Fig. 3, mistake
The outlet nozzle 6 of filter is connect by pipeline with internal oxygen generation system.
Such as Fig. 2, filter installation cavity has opening towards the side of hull outside, and opening is by equal with housing outer surface
Cover board 7 is closed.
As shown in Fig. 2, filter includes：Fixed cover 41 with filter installation cavity 3 inner side wall plate one and fixed cover pair
Filter bowl 42, the sealing ring 43 between fixed cover and filter bowl for closing installation.Outlet nozzle 6 extends inwardly into housing cavity, and with
Filter installation cavity inner side wall plate is integrally formed.
