After the installation, the waterway design of filter element group 3 and filter body 1 is that total water inlet 11 communicates with the raw water side 31 of filter element group 3, and the water purification side 32 of filter element group 3 is communicated with water outlet 12. Thus, the raw water to be purified, which is fed from the main water inlet 11, is fed to the raw water side 31 of the filter element assembly 3, enters the water purifying side 32 of the filter element assembly 3 for filtering and purifying water, and is finally fed out from the water outlet 12.

Preferably, the main water inlet 11 and the water outlet 12 are vertically arranged on the filter body 1, the related water paths are communicated and arranged, an inner sleeve 17 is formed in the inner cavity of the filter body 1, an external communication path 171 is formed by separating the inner sleeve 17 from the inner cavity wall of the filter body 1, and the communication path 171 is communicated with the main water inlet 11 and the raw water side 31 of the filter element assembly 3; the barrel cavity of the inner sleeve 17 is formed as an internal passageway 172 communicating the clean water side 32 of the cartridge module 3 with the water outlet 12.

In the preferred quick-assembly and disassembly type installation scheme, a quick-assembly and disassembly mechanism 5 is arranged between the filter element assembly 3 and the filter element assembly opening 16, and the quick-assembly and disassembly mechanism 5 mainly comprises a shifting piece 51 and a spring piece 52. The filter element assembly 3 has an assembly portion 33 assembled corresponding to the filter element assembly opening 16, a latch 53 is protruded from a side wall of the assembly portion 33, a socket 54 is provided on the filter element assembly opening 16, and the latch 53 can be inserted into the socket 54 in an axial matching manner. A clamping groove 55 capable of axially limiting the clamping block 53 is arranged beside the inserting hole 54, and a communication opening 551 is formed between the clamping groove 55 and the inserting hole 54; the latch 53 is inserted from the insertion opening 54, and then is rotated into the latch groove 55 through the communication opening 551, so that the latch 53 is axially limited by the latch groove 55.

A shifting piece groove 56 is arranged below the inserting hole 54, the shifting piece 51 is assembled in the shifting piece groove 56 through the spring piece 52, specifically, the spring piece 52 is sleeved on the shifting piece 51, and the upper end and the lower end of the spring piece are respectively supported on the top 511 and the groove bottom of the shifting piece groove 56. The shifting piece 51 is elastically supported by the spring piece 52, so that the top 511 of the shifting piece 51 is limited to be arranged at the automatic closing communication port 551 upwards, and the shifting piece 51 is provided with a hand-pulling part 512 extending out of the filter body 1.

The filter element assembly 3 is installed on the filter element assembling opening 16 of the filter body 1, as shown in fig. 8, the assembling portion 33 of the filter element assembly 3 faces the filter element assembling opening 16, the latch 53 is correspondingly inserted from the insertion opening 54, the latch 53 presses against the top 511 of the dial 51 to open the communication opening 551, and then the communication opening 551 is rotated clockwise until the communication opening is not rotated, the latch 53 is matched with the slot 55, the dial 51 automatically returns to the closed communication opening 551 under the elastic force of the spring element 52, and the filter element is installed. The axial direction of the fixture block 53 is limited by the clamping groove 55, and the radial direction of the fixture block 53 is limited by the top 511, thereby ensuring that the filter element assembly 3 is stably and reliably installed on the filter body 1.

The operation of disassembling the filter element assembly 3 from the filter element assembling port 16 of the filter body 1 is to pull down and not to release the hand-pulling portion 512 extending out of the filter body 1 as shown in fig. 9, at this time, the communicating port 551 is opened, the filter element assembly 3 is rotated counterclockwise (the inserting port 54 has a rotation stopping effect on the filter element), and then the hand-pulling portion 512 is released, and the filter element assembly is taken out upward. During the filter element group spare 3 change of present case filter, regardless of the installation still disassemble the operation, all very simple, quick.

Preferably, the top 511 of the pick 51 is designed as an inclined top surface to form a triangular top limit part, wherein the inclined high end part is arranged corresponding to the side of the communication port 551. Therefore, the closing effect of the communication opening 551 is realized, the pushing of the shifting piece 51 during installation is facilitated, and the shifting piece 51 can flexibly and smoothly move.

Preferably, the mounting manner of the pick 51 is that the bottom of the pick groove 56 has a bottom opening 571 therethrough, and the bottom of the pick 51 extends out of the bottom opening 571 and is provided with a barb part 513 limited on the bottom opening 571.

Preferably, the design mode of the shifting sheet groove 56 is that a shifting sheet box 57 is convexly arranged on the outer side wall of the filter body 1, the shifting sheet groove 56 is formed in the shifting sheet box 57, and an adjusting opening 572 is formed in the box surface of the shifting sheet box 57 and used for manual shifting and 512 stretching out and shifting up and down for adjustment.

Preferably, an auxiliary block 58 is further protruded on the side wall of the assembling portion 33 of the filter element assembly 3, and the auxiliary block 58 is arranged opposite to the block 53; the filter element assembling opening 16 is provided with an auxiliary groove for the auxiliary block to be rotatably arranged. Thus, the stability of the assembly of the filter element assembly 3 is improved by the matching of the auxiliary block 58 and the auxiliary groove.

Preferably, a month dial 7 is arranged on the filter element assembly 3. The specific scheme of the month dial 7 is that the month dial has an inner ring and an outer ring which can rotate relatively inside and outside, month scales are arranged on the outer ring, and a first mark 71 and a second mark 72 are arranged on the inner ring at proper intervals. When the filter element assembly 3 is replaced, an operator can conveniently adjust the month dial 7 on the filter element assembly, so that the current month scale is aligned with the first mark 71, and the month scale aligned with the second mark 72 is the month of the next replacement rate core assembly, thereby realizing the filter element replacement prompting function, being simple and easy to understand, and overcoming the trouble that a user forgets to replace time easily in use.
