Description

Water purifier filter element with cleaning function

Technical Field

The present invention relates to a water purifying apparatus.

Background

The service life of the existing water purifier filter element is expired, and two main forms are as follows: the first active carbon filter element has saturated adsorption capacity and loses adsorption effect; the second, activated carbon filter element, adsorption capacity saturation, lose adsorption, the second, RO membrane filter element, nanofiltration membrane filter element, ultrafiltration membrane filter element, PP cotton, ceramic filter element, etc., the hole is blocked, results in the water yield diminishes.

The RO membrane filter element and the nanofiltration membrane filter element can cause membrane surface blockage and water outlet flow reduction after being used for a period of time, ions in water before the membrane cannot be effectively removed in a flushing mode, so that concentrated water before the membrane is enriched, and the filtering effect is greatly reduced.

The current method of extending the life of the filter element is mainly flushing. The disclosed documents have various flushing technical schemes, but the prior technical schemes mainly use tap water to directly flow through the inside of the filter element, and the plug on the surface of the filter element is taken away by the fluidity of the tap water, so the technical scheme has the defects of low flushing efficiency, long flushing time, large waste water quantity and the like.

The Chinese patent application with the application number 201710608790.5 discloses a filter element cleaning structure and a water purifier filter element with the same (application publication number CN 107349794A), and the application aims to clean the filter element by adding water flow to the filter material through a water stirring mechanism. However, the water seal requirement is higher when the motor is installed, the water leakage risk exists, and the maintenance is not very convenient.

Disclosure of Invention

The invention aims to solve the technical problem of providing the water purifier filter element with the cleaning function, which has lower water seal installation requirement.

The invention aims to solve the technical problem of providing the water purifier filter element with a good cleaning effect and a cleaning function aiming at the technical situation.

The technical scheme adopted for solving the technical problems is as follows: the utility model provides a water purifier filter core with cleaning function, includes the casing, locates the filtration membrane subassembly in the casing and locates the end cover at casing tail end, aforementioned casing has water inlet and water purification export, its characterized in that the end cover inboard rotationally be equipped with the driven circle that can stir the water in the casing, this driven circle is equipped with driven magnet, correspondingly, the end cover outer wall has and can drive driven circle pivoted initiative circle under the rotation state, should be equipped with on the initiative circle and inhale or repulse initiative magnet with aforesaid driven magnet, the initiative circle external connection has one can be initiative circle pivoted drive mechanism.

In order to improve the water stirring efficiency, at least one stirring blade is arranged on the driven ring.

Further, the transmission is preferably designed in two ways:

First, the drive mechanism include driven gear and with driven gear meshing transmission's rack, this driven gear and initiative circle can realize synchronous rotation through a connecting axle.

The second kind, the said drive mechanism includes driven gear and driving gear which is meshed with driven gear, the driven gear and driving ring can realize the synchronous rotation through a connecting axle.

The outer wall of the end cover is provided with a shaft groove in running fit with the connecting shaft, and the shaft groove can be positioned, so that the driving driven coil with the accurate driving coil is ensured, and the working efficiency is improved.

Further, the shell is also provided with a waste water outlet, and the waste water outlet, the water inlet and the purified water outlet are all positioned at one end of the shell far away from the end cover.

The mounting structure of the driven coil is preferably set as follows: the filtering membrane component comprises a central tube connected with the water inlet of the shell and a filtering material positioned at the periphery of the central tube, the central tube is provided with a flowing water hole for flowing to the filtering material, the inner side of the end cover is provided with a convex ring, the tail end of the central tube is inserted into the convex ring, and the driven ring is sleeved outside the convex ring and is pressed by a pressing ring to enable the driven ring to be axially positioned relative to the convex ring.

Compared with the prior art, the invention has the advantages that: first, the vortex is generated, the water in the filter element is stirred, and the plug attached to the surface of the filter element is flushed down, so that the filter element flushing process is more efficient, the flushing time is reduced, and the flushing water is reduced. Second, because of the effectual washing, the effectual plug that adheres to filter core or filter core membrane surface washes away, can improve the filter core life-span greatly. And the third point is that the filter element with ion interception function such as an RO membrane filter element can prevent the inside of the filter element from having flushing dead angles through stirring water in the filter element, so that the enrichment of concentrated water is prevented, and the filtering effect and the service life of the filter element are greatly improved. Fourth, the magnetization process converts the large molecular group water into small molecular group water, so that the water can more easily pass through the filtering material, and the water purifying flow of the water purifier is improved. Fifth, the driven ring does not need to be arranged in a water seal mode, and installation requirements are reduced.
