Then take out the sealing ring 14. Then hook the first rotating rod 20 from the notch on the right part of the arc groove of the first filter screen 8 with your finger to make the first rotating rod 20 rotate. Then hold the rubber sleeve 21 with your hand and lift the first filter screen 8 upward. The first filter screen 8 moves upward, driving the second fixing block 10 and the rotating block 11 upward. The rotating block 11 rotates around the second fixing block 10 under the action of the third fixing block 13.Then, the elastic member 12 is squeezed, and the rotating block 11 is separated from the third fixed block 13. After the rotating block 11 and the third fixed block 13 are separated, the elastic member 12 is reset, and then the rotating block 11 is driven to reset. Then, a new first filter screen 8 is replaced, and after the rotating block 11 at the lower part of the new first filter screen 8 is aligned with the square groove 411, the first filter screen 8 is pressed downward from the upper part of the first filter screen 8. The first filter screen 8 moves downward, thereby driving the second fixed block 10 and the rotating block 11 to move downward, and the rotating block 11 rotates around the second fixed block 10 under the action of the third fixed block 13, thereby squeezing the elastic member 12, and then the rotating block 11 and the third fixed block 13 are buckled with each other. After the rotating block 11 and the third fixed block 13 are buckled with each other, the elastic member 12 is reset, thereby making the rotating block 11 and the third fixed block 13 The buckle is tighter, then rotate the first rotating rod 20, put the first rotating rod 20 into the arc groove of the first filter 8, then install the sealing ring 14, rotate the upper cover 5, the sealing ring 14 can form a seal between the upper cover 5 and the first cylinder 4, then move the second rotating rod 222 upward, rotate the lock 223, so that the lower part of the lock 223 and the upper part of the fourth fixing block 224 contact each other, so that the upper cover 5 and the first cylinder 4 can be fixed to each other, further deepening the sealing degree, the replacement method of the second filter 9 is the same as the first filter 8, so it will not be explained, so that when the first filter 8 and the second filter 9 are damaged, the first filter 8 and the second filter 9 can be easily disassembled and replaced, which brings convenience to the operation of the staff and increases the practicality and flexibility of the device.
