The utility model discloses a fixed structure of an exhaust valve core of a micro-piezoelectric rice cooker, which comprises an upper cover, a cover plate, an exhaust valve core and an exhaust valve. The upper cover is closed on the cover plate, an installation groove is arranged at the lower end of the upper cover, a fixed nut is installed in the installation groove, and the fixed nut is sleeved at the outer end of the lower end of the exhaust valve core. The lower end of the exhaust valve core extends a fixed nut to form an insertion end, and the insertion end shrinks downward. The outer end cover of the installation groove is provided with a sealing ring. The upper end of the sealing ring is provided with a sealing opening close to the outer side of the exhaust valve core insertion end and a funnel-shaped sealing opening. The lower end of the sealing ring is provided with an opening connected with the inner space of the cooker body, and the upper end of the exhaust valve core is connected with the exhaust valve. Because the sealing ring is provided with a sealing opening close to the outer side of the exhaust valve core insertion end and a funnel-shaped sealing opening, the exhaust valve core is inserted into the The utility model has the advantages of simple structure, convenient installation, good sealing performance of the electric rice cooker, avoiding easy damage of the sealing ring and high practicability.
【技术实现步骤摘要】
一种微压电饭煲的排气阀芯固定结构
本技术涉及厨房用具领域,具体涉及一种微压电饭煲的排气阀芯固定结构。
技术介绍
现有微压电饭煲及电压力锅主体排气阀芯固定方式主要有:1、排气阀芯通过螺母固定在金属锅盖上,依靠螺母压紧密封圈实现密封;2、排汽阀芯通过螺母固定在金属盖板上,依靠螺母压紧密封圈实现密封。上述两种固定方式存在以下缺点:微压电饭煲及电压力锅主体排气阀芯直接通过螺母固定在金属锅盖或盖板上时,需要依靠螺母压紧密封圈实现密封,锁紧螺母时螺母旋转易将密封圈弄破损导致产品密封不良,同时螺母旋紧时易划伤金属锅盖或盖板。
技术实现思路
为了克服现有技术的不足,本技术提供一种微压电饭煲的排气阀芯固定结构。本技术所采用的技术方案主要是:一种微压电饭煲的排气阀芯固定结构,包括上盖、盖板、排气阀芯和排气阀,所述上盖盖合在盖板上,上盖下端设置有安装槽,所述安装槽内安装有固定螺母,所述固定螺母套接在排气阀芯下端外侧,所述排气阀芯下端伸出固定螺母形成有插入端,所述插入端向下收缩呈锥形状,安装槽外端罩设有密封圈,所述密封圈上端设置有紧贴排气阀芯插入端外侧、漏斗状的密封口,密封圈下端设置有开口与煲体内部空间连通,排气阀芯上端与排气阀连通。作为上述技术方案的改进,所述上盖下端向下伸出形成有凸台,所述凸台中部内凹形成有所述安装槽,所述密封圈罩设于凸台上。作为上述技术方案的进一步改进,所述密封圈上端设置有与凸台配合的下沉部,密封圈通过下沉部贴合罩设在凸台上。进一步,所述下沉部中间内凹形成有所述密封口。进一步,所述上盖由塑料材质制成。本技术的有益效果是:本技术的排气阀芯通过固定螺母固定在上盖下端后再 ...
