[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-6 A kettle filter element includes a filter element body 1, a fixing member 2 is provided on the top of the filter element body 1, a water outlet 3 is provided inside the fixing member 2, two locking blocks 5 are installed on the outside of the fixing member 2, a base 6 is provided at the bottom of the filter element body 1, and an auxiliary limiting mechanism for limiting and fixing the filter element body 1 is provided inside the base 6.

[0024] As a technical optimization of this utility model, a first sealing ring 4 is installed at the top of the fixing member 2, and the first sealing ring 4 is engaged with the first sealing groove preset inside the kettle. The filter body 1 is installed from bottom to top in the filter groove set inside the kettle. After the filter body 1 is completely inserted into the filter groove, the first sealing ring 4 engages with the first sealing groove, thereby improving the sealing between the top of the filter body 1 and the filter groove.

[0025] As a technical optimization of this utility model, both ends of the two locking blocks 5 are provided with inclined surfaces, and both locking blocks 5 are engaged and adapted to the two pre-set slots inside the kettle. After the filter element body 1 is inserted into the filter element slot, by driving the filter element body 1 to rotate inside the filter element slot, the two locking blocks 5 on the outer wall of the fixing member 2 are rotated and engaged in the corresponding two slots, thus realizing the initial installation and fixing of the filter element body 1.

[0026] As a technical optimization of this utility model, a second sealing ring 7 is installed on the outer wall of the base 6, and the second sealing ring 7 is engaged and matched with a pre-set second sealing groove inside the kettle. After the filter element body 1 is fully inserted into the filter element groove, the second sealing ring 7 engages with the second sealing groove, thereby improving the sealing performance between the bottom end of the filter element body 1 and the filter element groove.

[0027] As a technical optimization of this utility model, the auxiliary limiting mechanism includes two movable slots 12 opened inside the base 6. Limiting blocks 9 are slidably installed inside the two movable slots 12. The ends of the two limiting blocks 9 that are close to each other are connected to the inner wall of the movable slots 12 through springs 13. The ends of the two limiting blocks 9 that are far apart are inserted into and adapted to the limiting slots preset inside the kettle.

[0028] As a technical optimization of this utility model, the base 6 has two sliding grooves 14 connected to the movable groove 12 inside. Each sliding groove 14 has a slider 15 installed inside it, and the end of each slider 15 away from the sliding groove 14 is connected to its corresponding limiting block 9. By means of the sliding cooperation between the slider 15 and the sliding groove 14, the movement trajectory of the limiting block 9 moving inside the movable groove 12 can be limited, ensuring that it moves back and forth along a straight line.

[0029] As a technical optimization of this utility model, the bottom of the base 6 has two rectangular slots 11 that are connected to the movable slot 12. The inside of each of the two rectangular slots 11 is equipped with a toggle plate 10. The top of each of the two toggle plates 10 is connected to its corresponding limiting block 9. A knob 8 is provided between the two toggle plates 10 on the base 6. During the initial installation of the filter element body 1, the knob 8 can be manually turned to rotate the filter element body 1 inside the filter element groove, allowing the two locking blocks 5 to engage in their corresponding slots. After the filter element body 1 enters the filter element groove, the arc surfaces of the two limiting blocks 9 at opposite ends will abut against the bottom of the filter element groove. When compressed, the two limiting blocks 9 will elastically contract with the help of the corresponding springs 13, causing them to retract into their corresponding movable slots 12. Once the filter element body 1 is fully inside the filter element groove, the knob 8 can be manually turned again to engage the two locking blocks 5 with their corresponding slots. The two limiting blocks 9 will then rotate into their corresponding limiting slots. With the elastic reset of the two springs 13, the two limiting blocks 9 will extend outward from their corresponding movable slots 12 and engage with their corresponding limiting slots. This process helps to further limit the installation of the filter element body 1 and improves its stability inside the filter element groove.

[0030] In this utility model, when installing the filter body 1 inside the filter cartridge slot of the kettle, the kettle can be placed flat on the top of the placement platform so that the filter cartridge slot inside is parallel to the placement platform. Then, the filter body 1 is manually inserted into the filter cartridge slot. At this time, the two limiting blocks 9 on the outside of the base 6 will be squeezed by the inner wall of the filter cartridge slot, causing it to be stored in the corresponding movable slot 12 until the first sealing ring 4 at the top of the filter body 1 is engaged with the first sealing slot opened inside the filter cartridge slot. Then, the knob 8 is manually turned to drive the filter body 1 to rotate inside the filter cartridge slot, so that the two locking blocks 5 on the outer wall of the fixing member 2 are engaged in the corresponding locking slots, achieving the effect of initial installation and fixing of the filter body 1.

[0031] After the two locking blocks 5 engage with their corresponding slots, the two limiting blocks 9 also rotate into their corresponding limiting slots. With the elastic reset of the two springs 13, the two limiting blocks 9 extend outward from their corresponding movable slots 12 and engage with their corresponding limiting slots. This helps to further limit the installation of the filter element body 1, improving the stability of the filter element body 1 inside the filter element slot. It also avoids the problem that although the filter element body 1 in the prior art is easy to disassemble and assemble, repeated disassembly and assembly can cause the sealing structure to loosen, reducing the stability of the filter element body 1 inside the filter element slot and causing leakage and damage. This ensures the safety and stability of the filter element body 1 during installation and use.

[0032] To remove the filter cartridge body 1 from the filter cartridge slot inside the kettle, you can manually pinch the two levers 10 with one hand to move them closer together until the outer walls of the two levers 10 on the closest side abut against the knob 8. This will cause the two springs 13 to contract elastically and simultaneously move the limiting blocks 9 into the corresponding movable slots 12, thus disengaging the two limiting blocks 9 from the two limiting slots. Then, you can manually turn the two levers 10 to rotate the filter cartridge body 1 in reverse inside the filter cartridge slot, causing the two locking blocks 5 to rotate out of the corresponding locking slots. Finally, pull the filter cartridge body 1 out to quickly disassemble it.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
