An improved filter

The utility model relates to the field of filter element manufacturing, and provides an improved filter, which comprises an upper cover, a filter element and a base. The upper cover and a base are respectively arranged at the upper and lower ends of the filter element. The filter element is a folding cylinder filter element consisting of a long strip filter paper folded repeatedly into a corrugated shape and the ends of the first and the last are bonded to form a hollow cylinder shape. The outer wall of the folding cylinder filter element is arranged on the circumferential outer wall of the folding cylinder filter element. There are at least two rings of external pressure rings, each ring of which is composed of plural external pressure grooves. The external pressure groove consists of a groove formed by pressing the corner of the folding part on the outer wall of the folding barrel filter core circumferentially to the central axis of the folding barrel filter core. Each outer pressure groove of each ring of the external pressure ring is arranged at intervals between the folding parts of the folding barrel filter core, and the outer side of the folding barrel filter core circumferentially. The external pressure grooves of the outer pressure rings of each upper and lower circles of the wall are staggered. The utility model solves the problems of unreasonable structure of the existing filter, deformation and folding to reduce the filtering area, and insufficient filtering area, etc.

一种改进型滤清器
本技术涉及滤芯制造
，特别涉及一种改进型滤清器。
技术介绍
常规的滤芯都有内护网和外护网。内护网主要起到增大抗压强度和加强支撑的作用，而外护网主要起到保护滤材的作用。大部分的空气滤芯和油滤芯，都是外压的，也就是空气或油是从外侧流向内侧。在现实生活中，经常出现，由于外力和阻力的作用下，滤纸或滤材发生严重的并折或变形现象，极大影响了过滤面积的有效利用和滤芯的使用寿命，使得滤芯的过滤质量不稳定，寿命较短，同时现有的滤芯的过滤面积不够大。因此，传统的滤芯还存在许多不合理的地方，需要作出改进完善。
技术实现思路
因此，针对上述的问题，本技术提出一种结构简单、能有效地避免滤芯的并折或变形现象发生、保证滤芯过滤面积的有效发挥、可以取代外护网的作用、有效节省原材料、降低成本的改进型滤清器。为解决此技术问题，本技术采取以下方案：一种改进型滤清器，包括上盖、滤芯和底座，所述上盖和底座分别盖设于滤芯上、下两端，所述滤芯为由长条形滤纸反复折叠成瓦楞状后且首尾两端粘结围成中空筒状造型构成的折叠筒式滤芯，所述折叠筒式滤芯圆周外侧壁上设有至少两圈外压环，各圈所述外压环均由复数个外压槽构成，所述外压本文档来自技高网...
