[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the present invention proposes a water purifier filter element installation structure, including:

[0022] A filter cartridge 1 is provided with a filter cartridge 2 installed therein, and a short tube 3 is installed at the upper end of the filter cartridge 2;

[0023] Installation assembly; the installation assembly includes two arc blocks 5 fixed in the filter cartridge barrel 1, the inner walls of the two arc blocks 5 are on the same circular surface, and the two arc blocks 5 are symmetrically distributed on the inner wall of the filter cartridge barrel 1, wherein the radius of the filter element 2 is smaller than the radius of the circumference of the arc blocks 5, so that it will not hinder the filter element 2 from being installed in the filter cartridge barrel 1.

[0024] It should be noted that the size of the arc block 5 is not as shown in the figure, and the setting of the arc block 5 does not affect the installation of the filter element 2, wherein the filter element 2 includes an external rubber sealing ring to ensure that the filter element 2 can be easily installed in the filter element barrel 1.

[0025] A deformation tube 6 and a pressure ring 9 are sleeved on the short tube 3. The deformation tube 6 is made of rubber. Two connecting plates 4 are fixed on the pressure ring 9. Two protrusions 8 are fixed on the upper ends of the two connecting plates 4. A spherical groove 7 is provided at the bottom of the arc block 5. The protrusion 8 is slidably connected in the spherical groove 7. The connecting plate 4 and the pressure ring 9 are integrally formed, and the connecting plate 4 and the pressure ring 9 are both made of plastic. The protrusion 8 is made of plastic, and the protrusion 8 is fixed to the connecting plate 4 by hot melt.

[0026] When in use, after the staff installs the filter element 2 in the filter cartridge 1, the staff puts the deformed tube 6 on the short tube 3, and then puts the pressure ring 9 on the short tube 3 and abuts the upper end of the deformed tube 6. At this time, the connecting plate 4 is not opposite to the arc block 5. Then press the two connecting plates 4 downward to deform them so that they are located under the arc block 5. Then rotate the connecting plate 4. The connecting plate 4 drives the pressure ring 9 to rotate so that the connecting plate 4 is located under the arc block 5. Then loosen the connecting plate 4. The connecting plate 4 is reset so that the protrusion 8 abuts against the bottom of the arc block 5. Then continue to rotate the connecting plate 4 until the protrusion 8 is located in the spherical groove 7. At this time, the connecting plate 4 abuts against the bottom of the arc block 5. Since the connecting plate 4 is limited and has downward pressure, it will radiate to the pressure ring 9. At this time, the deformed tube 6 of the rubber material is deformed, so that the filter element 2 can be locked in the filter cartridge 1, making it difficult to slide and move.

[0027] When disassembling, just press the connecting plate 4 and rotate it to separate from the arc block 5. The operation is simple and convenient.

[0028] The utility model can install and disassemble the filter element 2 by simply pressing the connecting plate 4 and rotating it. The operation is simple and quick, the structure is simple and the practicality is better. It is also easy to produce the pressure ring 9 made of plastic and with a simple structure, which reduces the production difficulty.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
