Rotary filter element structure

Abstract

The invention provides a rotary filter element structure, which comprises a filter element component and a filter element base, wherein the filter element component and the filter element base are connected through a spiral clamp slot structure. According to the rotary filter element structure provided by the invention, a filter element is communicated with three channels of the filter element base in one-to-one correspondence through a rotary member on the filter element component; thus, the filter element component can be changed without changing the positions of a water purifying channel, a wastewater channel and a water inlet channel, and the problem of water permeation among the water purifying channel, the wastewater channel and the water inlet channel can be prevented; meanwhile, the water inlet channel and the wastewater channel of the filter element are changed through angle change of the rotary member; the water purifying channel is autonomously closed under the sealing effect of a check valve so as to avoid water overflow at a butting port of the filter element; when the filter element is separated from the base, three channels on the base close and seal the base channels under the actions of respective springs so as to realize a function of sealing all parts of the filter element.

Description

technical field [0001] The invention belongs to the technical field of water purification equipment, in particular, the invention relates to a rotary filter core structure. Background technique [0002] At present, in the field of water purification and filtration, especially in the design of filter elements of water purifiers, in order to facilitate installation and replacement, the installation forms of filter elements are various. Considering the overall layout of the water purifier and the user experience, the filter body of the existing filter element is generally divided into two parts: the filter element and the filter element seat. When the life of the filter element expires, the user can take out the filter element and replace it. However, during the replacement process, there will be water overflow at the interface of the filter element of the water purifier, causing water to flow through the water purification pipe, waste water pipe and raw water pipe inside the w...

Problems solved by technology

When the life of the filter element expires, the user can take out the filter element and replace it. However, during the replacement process, there will be water overflow at the interface of the filter element of the water purifier, causing water to flow through the water purification pipe, waste water pipe and raw water pipe inside the water purifier. , resulting in poor user experience, especially when the filter element is installed upside down, when the filter element is taken out, water drips continuously
