The frame 201c includes a first filter plate 201d disposed inside the frame 201c and a second filter plate 201e disposed inside the frame 201c above the first filter plate 201d. The connecting assembly 202 includes an intrusion sleeve 202a disposed on the inner wall of the frame 201c, a sliding plate 202b disposed inside the intrusion sleeve 202a, springs 202c fixed on both sides of the sliding plate 202b, and a pull rod 202d fixed on the top of the sliding plate 202b. The fixing assembly 203 includes a guide rod 203a disposed inside the intrusion sleeve 202a, a connecting rod 203b fixed to the bottom end of the guide rod 203a, a stop block 203c fixed to the bottom end of the connecting rod 203b, a fixing ball 203d disposed on the side wall of the stop block 203c, and a blocking member 203e fixed to the bottom end of the stop block 203c.

[0034] Specifically, the side wall of the bearing block 201a is fixedly connected to the inner wall of the outer shell 101, the fixing bracket 201c is set above the bearing block 201a, the outer wall of the sliding plate 202b is slidably connected to the inner wall of the intrusion sleeve 202a, the outer wall of the pull rod 202d passes through the top end of the intrusion sleeve 202a, and the outer wall of the pull rod 202d is slidably connected to the inner wall of the top end of the intrusion sleeve 202a, the top end of the upper spring 202c is fixedly connected to the top of the inner wall of the intrusion sleeve 202a, the bottom end of the lower spring 202c is fixedly connected to the inner wall of the intrusion sleeve 202a, the top end of the guide rod 203a is fixedly connected to the bottom end of the sliding plate 202b, the outer wall of the guide rod 203a is slidably connected to the inner wall of the intrusion sleeve 202a, the side wall of the intrusion sleeve 202a is provided with a through hole, and the outer wall of the fixing ball 203d is set inside the through hole.

[0035] The operation process of this embodiment is as follows: When a large amount of oil stains accumulate on the first filter plate 201d and the second filter plate 201e, by pulling the pull rod 202d upward, during the upward movement of the pull rod 202d, the connecting rod 203b will be moved through the guide rod 203a. During the movement of the connecting rod 203b, the stop block 203c will be moved. At this time, the stop block 203c will disengage from the fixed ball 203d, so the movement of the fixed ball 203d will not be hindered. However, when the pull rod 202d is pulled upward, the inner wall of the bearing block 201a will force the fixed ball 203d to move into the interior of the bearing block 201a. The fixed ball 203d will not be stuck inside the fixed groove 201b. Then, by continuing to pull the intrusion sleeve 202a upward, the intrusion can be removed. The sleeve 202a is fully pulled out, thus completing the disassembly of the fixing frame 201c. The first filter plate 201d and the second filter plate 201e are fixedly connected to the fixing frame 201c, thus indirectly completing the disassembly of the second filter plate 201e. In addition, when installing the fixing frame 201c, the pull rod 202d is pressed down, causing the stop block 203c to move down and disengage from the fixing ball 203d, allowing the sleeve 202a to enter the interior of the bearing block 201a. Then, the pull rod 202d is released, and under the reset action of the spring 202c, the stop block 203c will be pulled back to its original position, and the fixing ball 203d will be pushed out. The fixing ball 203d will be stuck inside the fixing groove 201b, completing the installation of the fixing frame 201c.
