Technical Field

The invention relates to the field of water purification equipment, in particular to a filter element locking structure for a water purifier and a filter element assembly system using the same.

Background

Among the components constituting the water purifying apparatus, the filter element can be said to be one of the most core components. The filter core just needs to wash after working for a period of time or even change, and whether that is convenient with the process of filter core dismouting just more important to the user. At present, a plurality of filter elements are directly inserted into the sleeve, the filter elements are more convenient to disassemble and assemble in the arrangement mode, and water is easy to leak. Some water purifying devices are directly installed by a user through manual rotation, but the water purifying devices are inconvenient and easily damage filter elements.

Disclosure of Invention

The invention aims to provide a filter element locking structure for a water purifier and a filter element assembly system using the same, so as to solve the problem of inconvenience in disassembly and assembly of a filter element.

In order to achieve the purpose, the invention adopts the following technical scheme:

a filter element locking structure for a water purifier comprises a locking rotary disc and a filter element, wherein the locking rotary disc is matched with the bottom of the filter element in a locking manner; the locking carousel is connected with the elastic component that resets, and the elastic component that resets is used for the locking fixed to the locking carousel the elasticity that resets of filter core.

The working principle of the technical scheme is as follows:

under the state that the filter core installation was accomplished, filter core and locking carousel were in the stationary state that has accomplished the locking complex, this moment the filter core with the carousel all is in the locking position on, and the process of filter core locking and unblock as follows:

locking of the filter element: in the filter core installation, accessible external force makes the locking carousel rotate certain angle relative to the filter core, rotates the in-process and compresses the elastic component that resets, and when the filter core reachd the locking position, the elastic component that resets applys reset elasticity to the locking carousel and makes the locking carousel rotate in the opposite direction until reacing the locking position, accomplishes filter core locking process.

Unlocking the filter element: rotate the locking carousel through external force, make the locking carousel leave the locking position and break away from the locking cooperation relation with the filter core, it can to take out the filter core.

Specifically, the filter further comprises a sleeve for movably sleeving the filter element; the bottom of the sleeve is in linkage fit with the locking turntable. The sleeve can play a role in protecting the filter element; the sleeve is linked with the locking turntable, and the locking turntable can be rotated by rotating the sleeve.

Specifically, the sleeve upper end is provided with the plectrum, and the plectrum upwards extends and keeps away from the mounting hole axle center setting. The sleeve needs to be rotated when the filter element is detached, and the shifting piece is arranged, so that a user can conveniently rotate the sleeve, and the filter element is more convenient to disassemble and assemble.

Specifically, the periphery of the bottom of the sleeve extends downwards to form a plurality of convex strips, and the periphery of the locking turntable is provided with grooves meshed with the convex strips; after the convex strips are arranged in the grooves to realize meshing, the sleeve and the locking turntable are in a linkage state.

Specifically, the bottom of the filter element is provided with a plurality of clamping blocks, and the locking turntable is provided with a plurality of clamping grooves corresponding to the clamping blocks; the upper side of the clamping groove is provided with a guide inclined plane, and the reset elastic piece is linked with the clamping groove and is applied with reset elasticity clamped on the clamping block; the clamping block is provided with a clamping inclined plane matched with the guide inclined plane. The filter element is pushed inwards towards the sleeve, when the filter element is contacted with the locking turntable, the guide inclined surface is matched with the clamping inclined surface, the clamping inclined surface is pushed away while the filter element is guided to slide into the locking turntable, the locking turntable rotates, the clamping block can smoothly reach a locking position opposite to the clamping groove, and the reset elastic piece also stores force in the process; after the clamping block reaches the position opposite to the clamping groove, the reset elastic piece applies reset elasticity to the locking tray, so that the clamping groove rebounds to the locking position to clamp the clamping block, and the locking turntable locks the filter element.

Specifically, the elastic reset piece is a torsion spring arranged at the center of the bottom of the locking turntable. One end of the torsion spring is connected with the locking turntable, the other end of the torsion spring is fixed on the external device, when the turntable rotates, one end of the torsion spring connected with the locking turntable moves along with the rotation of the locking turntable, and the other end of the torsion spring is fixed, so that the torsion spring is in a force storage state, and the resetting elasticity can be provided for the installation of the filter element.

Specifically, locking carousel bottom center department is provided with the pivot that upwards extends, and filter core bottom center department is provided with the through-hole that corresponds with the pivot. The through-hole is installed in the pivot, makes the rotation of carousel go on around the filter core all the time, plays limiting displacement to the filter core simultaneously.

Specifically, the top of the filter element is also provided with a lifting handle for a user to lift. Make things convenient for when filter core dismouting to pull the filter core outward toward the sleeve, make the filter core dismouting more convenient.

The invention also provides a filter element assembling system, which comprises a main frame, wherein at least two mounting holes for inserting and mounting filter elements are arranged on the main frame, the positions corresponding to the inserting and mounting positions of the filter elements are corresponding, and a filter element locking structure as claimed in any one of claims 1 to 8 is applied on the main frame. The filter core locking structure is inserted in the mounting hole of the main frame, the main frame is mounted in the corresponding water purifying equipment, and only the main frame needs to be directly disassembled and assembled during disassembly and assembly without operating the filter core locking structure. The integrity of the filter element locking structure is protected, and the filter element locking structure is not easy to damage.

The invention has the beneficial effects that: compared with the mode of installing the filter element in the prior art, after the filter element is directly inserted into the sleeve in the scheme, the locking turntable can automatically lock the filter element, so that the installation is labor-saving and simple, and the installation is firm and is not easy to loosen; when the filter element is disassembled, the poking piece is only needed to be slightly poked to pull out the filter element, so that the filter element is convenient to clean and replace, and the cleanness of the filter element is kept.
