The utility model discloses a straight plug type filter core, including a filter bottle and an inner core set inside the filter bottle. The filter bottle includes a bottle body and a filter head located at the upper end of the bottle. The filter head is formed with a water intake and a water outlet. The outlet port of the outlet is connected with the outlet channel of the inner core, and the bottom of the bottle body is open with an assembly mouth, and the assembly mouth is sealed and fixed with a lower end cover. The direct inserted filter core of the utility model is simple in structure and low in material and process cost, and is especially suitable to be used as a whole discard filter core, and there is no pollution problem caused by replacing the inner core. By opening the port of the filter core to the bottom of the filter bottle, there is no relative motion between the inner core and the filter bottle during the spin melting, therefore, The problem of inner core seal will not be affected by rotary melting. That is to say, the scheme ensures the simple structure and low cost and solves the problem of sealing at the same time.

本技术涉及净水
,具体地说,是涉及一种直插式滤芯及包含其的净水机。
技术介绍
直插式滤芯多为旋熔抛弃式滤芯,申请号为201310677045.8的中国专利申请提出了一种一体式滤瓶,其包括上盖、桶身以及滤芯,滤芯装入桶身后,上盖与桶身旋熔固定,旋熔时,上盖相对于桶身高速旋转,滤芯与桶身相对静止,因此,上盖相对于滤芯同样是高速旋转,上述方案中,滤芯的出水端口与上盖的出水通道密封接触,因此旋熔时上盖与滤芯的出水端口相对转动摩擦产生热量出现烧伤上盖的出水通道内壁或者滤芯出水端的外壁,或者转动过程中产生划痕,均会导致上盖的出水通道内壁与滤芯出水端的外壁之间密封不牢漏水现象,在有的方案中,为了保证滤芯与上盖的密封性能,上盖与滤芯之间一般设置密封圈,在旋熔过程中,密封圈与上盖迅速摩擦产生热量,在旋熔后会产生烧伤密封圈或者上盖的情况,同样会在烧伤处易产生密封不牢漏水现象。目前有的一些直插式滤芯通过将滤瓶的上端结构设计的较复杂,滤瓶的上端包括滤瓶头、滤瓶座等多个可拆卸式结构设计,滤瓶头与内芯之间不需要密封,在内芯放入滤瓶之后,将滤瓶头与滤瓶旋熔固定,因 ...
