The utility model relates to an improved structure of a sealing component of a mushroom culture bag, which is applied to the sealing of the mouth of a mushroom culture bag. The improved structure of the sealing component of the mushroom culture bag includes the neck sleeve and the sponge block, which is also characterized by the top cover and the double inserts inside and outside the neck sleeve; the top cover with the cover hole; the sponge block is close to the cover hole in the top cover; the inner and outer double inserts of the neck sleeve are composed of the inner plug column and the outer insert ring, the top of the inner plug column and the outer insert ring are flush, and are respectively vertically connected with the inner and outer edges of the concentric ring piece; the inner plug column The inner hole is opened, the upper end of the through hole is connected with the center of the concentric ring, and the lower end of the through hole is connected with the outside; the top cover is on the top of the inner and outer double inserts of the neck sleeve, the inner side of the top cover is sealed with the outer side of the outer insert ring, and the edge of the sponge block is compacted on the inner surface of the top cover by the concentric ring piece. The utility model has the advantages of greatly improving the air permeability, good sealing effect around the air passage, and reducing the probability that the air passage is completely blocked by the bacteria material in the bag during the movement of the bacteria bag.

食用菌培养袋封口组件的改进结构
本技术涉及食用菌培养袋封口组件的改进结构,应用于食用菌培养袋袋口的密封。
技术介绍
中国技术专利公告了题为《海棉碟托式食用菌培养袋封口组件》(授权公告号为CN203748304U)的专利技术创造,它包括颈套、海绵块、插封盖、碟托四个组件。插封盖带盖孔;颈套呈圆筒状,一端向外张开喇叭口,另一端是直口;海绵块位于插封盖内紧贴盖孔;插封盖开口端从颈套直口端方向套插在颈套上;碟托呈圆碟状,平浅底,底面靠近外圆环形分布5~8个透气孔;海绵块呈圆柱形,装在碟托内;碟托外缘卡入插封盖内部环形凹槽之中。使用时,把袋口薄膜捏成束,穿过颈套内部后展开袋口薄膜并外翻,让袋口薄膜裹在颈套外侧面。最后把插封盖套插在颈套上夹紧袋口薄膜固定。这种结构的不足之处是在蒸气高温灭活中袋内向外的透气量小,需要较长的时间蒸气灭活;在使用环境中容易进水造成感染。
技术实现思路
本技术的目的在于克服上述现有技术中的不足之处,提供一种透气量大的、在使用环境中不容易进水的食用菌培养袋封口组件的改进结构。本技术的目的可以通过下述技术方案来达到:食用菌培养袋封口组件的改进结构,包括颈套、海绵块;其特征是还包括顶盖和颈套内外双插封件;顶盖带盖孔;海绵块位于顶盖内紧贴盖孔;颈套内外双插封件由内塞柱和外插封环组成,内塞柱和外插封环顶部平齐,分别与同心圆环片内外边缘垂直连接;内塞柱内部开通孔,通孔上端与同心圆环的中心连通,通孔下端与外界连通;顶盖盖在颈套内外双插封件顶端,顶盖内侧面与外插封环的外侧面密闭配合,同心圆环 ...
