In a further embodiment, aforesaid plurality of first floor may include：Multiple first narrow rib plates and multiple first are wide Floor.Plurality of first floor interval setting wide, multiple first narrow rib plates are set between two neighboring first floor wide.It is foregoing Multiple second floors may include：Multiple second narrow rib plates and multiple second floors wide, multiple second floor interval settings wide are adjacent Multiple second narrow rib plates are set between two the second floors wide.It should be readily apparent to one skilled in the art that " width " " narrow " herein is Comparatively.

In certain embodiments, each first floor wide caves inward to be formed from its side surface for forming first surface First groove；Each second floor wide caves inward to form second groove from its side surface for forming second surface, so that On the premise of ensureing the thickness very little (volume very little in other words) of support frame 32, the connection of its inner mesh structure is improve Property.

In a further embodiment, the part surface away from first surface of each the first floor wide prolongs towards the second floor Extend concordant with second surface, and cave inward to form the 3rd groove from the part surface concordant with second surface；3rd ditch Groove connects to form crisscross grooves with the position that second groove is intersected.At least one second rib wide in aforesaid plurality of second floor wide The part surface away from second surface of plate extends to concordant with first surface and certainly concordant with first surface towards the first floor The part surface caves inward to form the 4th groove；Wherein the 4th groove connects to form cross with the position that first groove is intersected Groove.In some embodiments of the present utility model, for the ease of the flowing of air-flow, as shown in figure 8, the inner surface of ceiling plate portion 26 Multiple wind-guiding floors can be extended downwardly out, with guide the air-flow from blower fan 60 flowed through in accommodating chamber controlled atmosphere membrane module 30 each The outer surface away from oxygen rich gas collecting chamber of controlled atmosphere film 31.Multiple wind-guiding floors are divided into two groups, including first group of wind-guiding Second group of wind-guiding floor that floor and first group of wind-guiding floor are set on a plane symmetry.Every group of wind-guiding floor includes first Wind-guiding floor, at least one second wind-guiding floors and at least one the 3rd wind-guiding floors.First wind-guiding floor is from centrifugal blower Extend to the side of accommodating chamber at air outlet, and extend to a lateral outer side of controlled atmosphere membrane module 30.Each second wind guide rib Plate is arranged between two the first wind-guiding floors, and between controlled atmosphere membrane module 30 and centrifugal blower.Each the 3rd wind guide rib Plate is located at a lateral outer side of controlled atmosphere membrane module 30, to guide air-flow air-flow is entered from the both lateral sides of controlled atmosphere membrane module 30 Gap between controlled atmosphere membrane module 30 and the basal surface or top surface of accommodating chamber.

So far, although those skilled in the art will appreciate that herein it is detailed have shown and described it is of the present utility model many Individual exemplary embodiment, but, in the case where the utility model spirit and scope are not departed from, still can be public according to the utility model The content opened directly determines or derives many other variations or modifications for meeting the utility model principle.Therefore, this practicality is new The scope of type is understood that and regards as covering all these other variations or modifications.
