Description

Quick installation type auxiliary extraction filter structure

This creation relates to a filter, especially a filter structure with quick installation type auxiliary extraction.

Existing filters (water filters, water purifiers) need to be replaced after a period of use. Because the disassembly directions of the cylinder body, the filter element and the cover are fixed, the disassembly and assembly operations are inconvenient, especially Some filters are limited by space constraints, and there will be inconvenient disassembly and assembly.

When the existing filters (water filters and water purifiers) filter substances that are harmful to the human body, the replacement of the filter element will cause direct or indirect contact to cause harm to the human body.

In order to improve the tightness of the filter element installed on the filter, the amount of interference between the filter element and the assembly hole of the filter is large, which will directly cause physical load to the installation operator, and the filter element is also prone to the release of filtered substances due to operational errors; The quick installation type auxiliary extraction filter structure adopts the screw tightening method to install the filter element, so that the installation force can be dispersed to avoid insufficient force.

The structure of the conventional filter includes a lower shell, an upper shell and a filter element, wherein the top surface of the lower shell is provided with a plurality of locking grooves and a plurality of notches, and the filter element is provided with a plurality of locking parts, when the filter element is installed. , it is necessary to align each of the catches with each of the gaps, and then rotate the filter element so that each of the catches is combined with each of the catch grooves. This installation method is not intuitive, and there is still room for improvement.

In view of this, how to eliminate the above deficiencies is the technical difficulty that the creator of this case intends to solve; however, the creator of this case, based on years of experience in the relevant industry, has Years of painstaking research and trial improvement, finally successfully developed this case, and made this new model born to enhance its efficacy.

In view of the above shortcomings, the novel quick-installation auxiliary extraction filter structure includes: a casing with an accommodating space inside, and two ends of the casing are respectively a closed end and a The open end that is connected in space, the open end is provided with a plurality of wall bodies, the inner side of the wall body is provided with a catch portion, the bottom width of the catch portion is greater than the top width of the catch portion, so that the catch portion is A slope is formed on one side; and a filter unit, the top of which is combined with a fixing element, the fixing element includes a plurality of plate bodies, each plate system is arranged at intervals, and the width of each plate body is larger than that of the filter unit, and each plate body is Press along the slopes of the latching parts to make the filter unit enter the accommodating space, and the plates are respectively located at the bottom of the slopes; rotate the fixing element to make the plates leave the latching parts the bottom of the filter unit, thereby taking out the filter unit.

Please refer to the first and second drawings. The structure of the new quick-installation auxiliary extraction filter includes: A casing 10 has an accommodating space 11 inside, and two ends of the casing 10 are respectively a closed end and an open end communicating with the accommodating space 11 , and a plurality of walls 12 are spaced between the open ends. , the inner side of the wall body 12 is provided with a latching portion 13 , the bottom width of the latching portion 13 is greater than the top width of the latching portion 13 , so that one side of the latching portion 13 forms an inclined surface 131 .

A flange 14 surrounds the outer side of the casing 10 . The flange 14 is located on the outer side below the wall body 12 . The diameter of the other end is larger than that of the flange 14 , and the diameter of the other end is smaller than that of the flange 14 . The first coupling member 15 is provided for detachable coupling with a second coupling member 16 , and the second coupling member 16 has an interior chamber 161 .

Referring to the second and third figures, a filter unit 20 has a fixing element 30 on the top thereof. The fixing element 30 includes a plurality of plate bodies 31 , and the plate bodies 31 are arranged at intervals, and the The width is larger than that of the filter unit 20 ; one end of the second coupling member 16 is detachably coupled with the first coupling member 15 , so that the fixing element 30 is located in the chamber 161 .

The filter unit 20 further includes a filter element 21 and a filter shell 22 covering the outside of the filter element 21. The outside of the filter shell 22 is provided with a plurality of hollow parts 221. The top of the filter shell 22 has a neck 222. The neck The diameter of the portion 222 is smaller than the diameter of the filter housing 22 , and the fixing element 30 is combined with the neck portion 222 .
