Description

Technical Field

[0001] The utility model belongs to the technical field of filters, and in particular relates to a filter element fixing structure of a pure water filter used in cigarette production. Background Art

[0002] The water used in the production of cigarette silk must be purified water. Therefore, tap water needs to be filtered through a filter to form purified water before it can be used. The filter currently used has 23 filter elements evenly distributed vertically inside. The lower end of the filter element is supported and limited by the lower limit plate, and the upper end of the filter element is supported and limited by the upper limit plate. When installing multiple filter elements inside the filter, first insert the limit heads at the bottom of the multiple filter elements into the corresponding holes on the lower limit plate. Since there is no other supporting and limiting structure in the middle, and due to the large number of filter elements, human hands cannot reach in to fully support them. The upper parts of multiple filter elements are tilted and easy to shake when the upper limit plate is not installed, resulting in the holes on the upper limit plate and the limit plugs on the upper part of the filter element. It is difficult to fit them together one by one. Now it generally requires four people to do it at the same time and takes 4 hours to complete, which greatly reduces the installation efficiency. Therefore, it is necessary to propose improvements. Utility Model Content
