Abstract

本实用新型属于民用压力锅的安全防堵类零 件。主要解决压力锅的堵阀,爆锅及喷出的气体,饭 渣伤人问题,是安装于压力锅的排气阀道内侧的安全 防堵罩。罩盖用冲压工艺制成具有凹凸不平的壳体 表面和其间的细长条状缝隙,并有向内侧凸起的斜螺 旋结构,罩底是向外翻边形状,是防堵防爆理想结构, 有效解决饭渣堵锅或爆锅问题。

Description

本实用新型属于民用压力锅的安全防堵阀类零件。
经查在国内现公开的专利文件中尚未此项相同的报导,在中华人民共和国专利文件88204452.4号中叙述的《高压锅安全防堵罩》采用罩盖与罩底的过渡或过盈配合联接方法,这种方法易脱落,不安全。
本实用新型的目的是提出一个改进型的压力锅安全防堵罩,使压力锅的使用更安全。此设计利用有凹凸表面和在其间形成的细长缝隙孔的壳体,达到防止饭渣、皮等物体堵塞排气阀道的目的,同时利用罩盖上向内侧凸起的斜螺旋与罩底翻边旋紧自锁,防止脱落。
技术内容:压力锅安全防堵罩(1)和罩底(3)都是采用金属薄片冲成的壳体,罩底(3)安装于压力锅盖排气阀管内侧,与罩盖(1)用斜螺旋旋紧,并要求达到自锁,防止脱落,便于拆卸清洗。
罩盖(1)利用形状类似阴阳花键轴的冲模,一次冲压成有凸凹表面,并在其间有条状缝隙孔的圆柱形壳体,开孔方向是沿圆柱壳体的园切线方向,比打园孔工艺简单,造价低,又是空间防堵的最佳结构。
罩底(3)是冲成向外翻边的喇叭状或正多边形的结构。
附图说明:罩盖(1)是冲压成具有凹凸表面和在其间的细长孔缝的园柱壳体,罩底(3)安装于压力锅盖排气阀管内侧。利用罩盖(1)向内侧凸起的斜螺旋(2)与罩底(3)的翻边旋紧自锁。

Claims (2)

1、一种压力锅安全防堵罩,包括由金属板制成的罩盖和罩底壳体,在罩盖上有凹凸不平表面和在其间形成的条状缝隙,其特征在罩盖(1)有向内侧凸出的斜螺旋(2),罩底(3)呈外翻边的喇叭状或呈外翻边的正多边形结构。
2、根据权利要求1所述的压力锅安全防堵罩,其特征在于罩盖(1)和罩底(3)结合时,罩底(3)的翻边应落在罩盖(1)的斜螺旋(2)的斜坡上。
