Specific embodiments

[0024] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] In order to improve the convenience of use, as Figures 1-6 shown, a membrane filter assembly for a filtering device that is easy to assemble according to the present utility model includes a water box 1, a threaded sleeve 2, a filter element assembly 3 and a quick closing assembly 23. The threaded sleeves 2 are arranged at equal distances along the bottom of the water box 1. The filter element assembly 3 is installed at the bottom of the threaded sleeve 2. A water supply channel 22 is provided at the center of the threaded sleeve 2. A water outlet channel 21 is opened inside the threaded sleeve 2 and on the outer periphery of the water supply channel 22. The quick closing assembly 23 is arranged in the water supply channel 22.

[0026] During use, a membrane filtration assembly with high convenience of assembly and replacement is provided for water users through the water box 1, the threaded sleeve 2, the filter element assembly 3 and the quick closing assembly 23. When replacing the filter element, the user does not need to cut off the valve of the water supply pipeline in advance, reducing the steps of filter element replacement and assembly. Moreover, when one set of filter elements is retained, the water filtration operation can be maintained without affecting the water filtration process, improving the convenience of use.

[0027] The present utility model further includes that the quick closing assembly 23 includes a plug post 231, a top cap 232 and a tension spring 233. The top cap 232 is connected to the top of the plug post 231. The tension spring 233 is sleeved on the plug post 231, and the bottom of the plug post 231 is inserted into the water supply channel 22;

[0028] ​Both ends of the tension spring 233 are respectively connected to the bottom of the top cap 232 and the top of the threaded sleeve 2.

[0029] A water outlet hole 235 is provided at the center of the bottom of the plug post 231. An inlet water hole 234 is provided at the bottom of the outer periphery of the plug post 231. A sealing ring 236 is sleeved on the top of the outer periphery of the plug post 231.

[0030] When in use, when the plug post 231 is further pulled into the water supply channel 22 by the tension spring 233, the sealing ring 236 can improve the sealing performance between the top of the outer periphery of the plug post 231 and the water supply channel 22.

[0031] The utility model further includes that the filter element assembly 3 includes a core shell 31 with a threaded joint at the top and a filter element 32. The filter element 32 is inserted into the core shell 31. An inlet joint 33 with the same inner diameter as the water supply channel 22 is arranged at the center of the top of the filter element 32. A sealing gasket 34 is arranged at the top of the filter element 32 and on the outer periphery of the inlet joint 33. An outlet water hole 35 is provided at the top of the filter element 32 and on the outer periphery of the sealing gasket 34.

[0032] The utility model further includes that the diameter of the inlet joint 33 is the same as the diameter of the plug post 231.

[0033] Both ends of the water box 1 are respectively provided with a raw water joint 11 and a purified water joint 12. The raw water joint 11 is connected to the water supply channel 22 through a pipeline. The purified water joint 12 is connected to the water outlet channel 21 through a pipeline. A one-way valve is installed on the water outlet channel 21.

[0034] The water outlet channel 21 installed with a one-way valve will only drain water to the purified water joint 12 and will not backflow.

[0035] When the utility model is in use, the raw water joint 11 is connected to the tap water supply pipeline of the water-using site, and the purified water joint 12 is connected to the indoor water-using pipeline, so that the tap water enters the indoor water-using pipeline after being filtered by the membrane filtration mechanism of the present application. During filtration, the tap water first flows through the raw water joint 11 to the water supply channel 22, and after passing through the water supply channel 22, it enters the inside of the filter element 32 through the inlet joint 33. And the tap water is filtered by the filter element 32 and then discharged to the outside of the filter element 32, and is discharged into the water outlet channel 21 from the outlet water hole 35, and then is conveyed to the indoor water-using pipeline by the purified water joint 12 to complete the filtration of the tap water;

[0036] After using for a period of time, when the filter element 32 needs to be replaced and reassembled, the user only needs to rotate the core shell 31 to threadedly remove the core shell 31 from the threaded sleeve 2. Then, a new filter element 32 can be installed into the core shell 31, and the core shell 31 can be installed on the threaded sleeve 2. During this process, there is no need to close the water valve, and the filter element 32 that has not been removed can still carry out normal filtering operations. Because after the core shell 31 is removed, the water inlet joint 33 of the filter element 32 will gradually withdraw from the water supply channel 22, and the plug 231 of the quick-closure assembly 23 is pulled back by the tension spring 233. The sealing ring 236 section on the upper part of the plug 231 will enter the water supply channel 22 to block the water supply channel 22, so that the water supply channel 22 will no longer drain water to this group of threaded sleeves 2, thus greatly improving the convenience of use.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
