Description

Protection structure of compound bending of filter core Technical Field The utility model relates to the technical field of filter element protection, in particular to a protection structure for composite bending of a filter element. Background The filter cartridge is the core component of the filter, and its performance directly affects the filtering effect and the service life. In order to improve the use effect and the suitability of the filter, a part of the filter is provided with a filter element with a bending part. When the traditional bending type filter element is used, the traditional filter element is easy to damage at the bending position due to stress concentration, so that the filtering efficiency is reduced and even fails, and the bending position is easy to damage due to impact, so that a protection structure is required to be arranged at the bending position of the filter element. The protection structure of traditional filter core department of bending adopts the support frame that has the metal mesh to protect, however the metal mesh receives the external force after the easy deformation to the filter core department of bending and applys effort, and is general to the protection effect of filter core department of bending, support frame and metal mesh fixed connection simultaneously can not carry out position control according to actual conditions, and use flexibility and suitability are relatively poor, and the result of use is general.
