DETAILED DESCRIPTION

[0017] See also Figure 1-Figure 3 The water purifier filter element installation structure includes a shell 1, a shell cover 2 and a filter element 9. The shell cover 2 is detachably connected to the upper end of the shell 1. The filter element 9 is installed inside the shell 1. The upper end of the shell cover 2 is fixedly connected with a handle 3. The handle 3 is arranged on the shell cover 2, so that after the filter element is placed inside the shell 1, it is convenient to hold the shell cover 2 and plug it into the shell 1;

[0018] A sealing ring 10 is fixedly connected to the outer side of the lower end of the shell cover 2, and a circle of annular groove 11 is formed on the outer side of the upper end of the shell 1. The sealing ring 10 is plugged into the annular groove 11. When the shell cover 2 is plugged into the shell 1, the sealing ring 10 is plugged into the annular groove 11. The sealing ring 10 is made of rubber, which can improve the sealing between the shell 1 and the shell cover 2.

[0019] The left and right ends of the shell 1 are fixed with lower side seats 4, the left and right ends of the shell cover 2 are fixed with upper side seats 5, the lower end of the upper side seat 5 is fixed with a concave frame 12, one end of the inner wall of the concave frame 12 is fixed with a group of gear blocks 13, the upper end of the lower side seat 4 is provided with a slot 14, the internal bearing of the slot 14 is connected with a shaft 15, the outside of the shaft 15 is fixed with a gear 16, the gear 16 is located inside the concave frame 12 and is meshed with the gear block 13. When the shell cover 2 is plugged into the shell 1, the concave frame 12 of the upper side seat 5 is aligned with the slot 14 of the lower side seat 4 and inserted, at this time, the gear 16 will be located inside the concave frame 12 and meshed with the gear block 13, and at this time, the gear 16 drives the shaft 15 to rotate;

[0020] The inner wall of the slot 14 is provided with a ratchet groove 21, and a ratchet pawl mechanism located in the ratchet groove 21 is installed outside the shaft 15, and the ratchet pawl mechanism includes a ratchet 17, a rotating shaft 18, a pawl 19, and a spring 20. The ratchet 17 is located in the ratchet groove 21 and fixed to the outside of the shaft 15, and the rotating shaft 18 is located above the ratchet 17 and connected to the bearing of the ratchet groove 21, and the pawl 19 is fixed to the other end of the rotating shaft 18, and the pawl 19 is connected to the ratchet 17. When the gear 16 drives the shaft 15 to rotate, the shaft 15 will drive the ratchet 17 to rotate synchronously, and when the concave frame 12 moves downward, the ratchet 19 is connected to the ratchet 17. The rotation direction of the wheel 17 and the gear 16 will not conflict with the pawl 19, so the pawl 19 will not affect the rotation of the ratchet 17. When the concave frame 12 needs to move up, the pawl 19 will resist the ratchet 17, so as to play a self-locking role on the gear 16. In this way, the plug-in installation is adopted, that is, the concave frame 12 under the upper side seat 5 is aligned with the slot 14 of the lower side seat 4 and inserted, and then as the gear 16 meshes and rotates with the tooth block 13 until the shell cover 2 is covered on the outer shell 1, the gear 16 is self-locked by the ratchet pawl mechanism, which can prevent the concave frame 12 from moving out of the slot 14. This is more convenient to install and can be directly plugged in.

[0021] The spring 20 is connected between the upper end of the pawl 19 and the inner top of the ratchet groove 21. By providing the spring 20, the pawl 19 can be tightly attached to the ratchet 17, and the use will not be affected by the installation direction of the water purifier and the filter element 9.

[0022] A lever 7 is fixed to one side of the end of the pawl 19, and an arc 6 communicating with the ratchet groove 21 is opened on the side of the lower side seat 4. The arc 6 extends from the end of the lever 7. When the filter element 9 needs to be removed, the lever 7 is pushed, and the lever 7 slides along the arc 6. The lever 7 drives the pawl 19 to rotate and separate from the ratchet 17. At this time, the pawl 19 squeezes the spring 20, and the shell cover 2 can be moved up. At this time, the concave frame 12 moves up and can drive the gear 16 to rotate in the opposite direction through meshing, and finally the filter element 9 is taken out, thereby facilitating the installation and removal of the filter element 9 and improving the speed of replacing the filter element 9.

[0023] A pull rope 8 is fixed between the ends of the levers 7. By fixing a pull rope 8 between the two levers 7, the two levers 7 can be pulled to slide along the arc track 6 at the same time, which makes it more convenient to unlock the two gears 16 at the same time.
