Description

Novel filter element structure with good sealing performance Technical Field The utility model relates to the technical field of filter elements, in particular to a novel filter element structure with good sealing performance. Background Along with the continuous development of water treatment technology, the structural design of the filter element has become a core element for improving the efficiency of the water purifying equipment. The joint of the traditional filter element shell is waterproof by relying on a single-layer sealing ring, but when the filter element is frequently detached and replaced, the sealing ring is easy to displace or elastically fatigue, particularly in a threaded connection structure, friction generated by rotary assembly can lead to abrasion of the sealing ring, interface leakage is easy to be caused after long-term use, and the tightness of a filtering system is influenced; in order to solve the problems, the application provides a novel filter element structure with good sealing performance. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides a novel filter element structure with good sealing performance, wherein a sealing ring arranged in the filter element only bears a static sealing function, rotary friction is borne by the outer wall of a convex ring and the inner wall of a groove, the sealing performance can be still maintained after the filter element is disassembled and assembled for a plurality of times through testing, and the filter element structure can effectively purify and remove peculiar smell of water through the cooperation of polypropylene fiber, activated carbon fiber cloth and a nano ceramic film and has strong practicability. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a novel filter core structure that sealing performance is good, includes first casing, one side of first casing is equipped with the second casing, the one end fixedly connected with first sealing washer that the second casing is close to first casing, the outer wall of first sealing washer offsets with first casing and sets up, the contact portion of first casing and second casing bonds there is waterproof sealing cloth, run through on the second casing be equipped with rather than fixed connection's hollow post, the outer wall fixedly connected with retainer plate of hollow post, establish to the holding tank between the inner wall of retainer plate and second casing, run through on the first casing and be equipped with rather than fixed connection's conveyer pipe, be equipped with seal structure between hollow post and the conveyer pipe, the outer wall cover of conveyer pipe is equipped with the filter core, the both ends of filter core offset with the inner wall of first casing and the lateral wall of retainer plate respectively and set up, run through on the conveyer pipe and seted up a plurality of through-holes.
