In some exemplary embodiments, as shown in fig. 3, 6, 7, 9 and 10, the rotating assembly 53 is fixed to the bracket 40, and the toggle member 52 is pivoted to the bracket 40. Specifically, the bracket 40 is provided with a mounting post, the toggle member 52 is provided with a mounting hole, and the mounting post and the mounting hole are fixedly connected through a bolt. The rotating piece 531 is provided with a driving bevel gear, the poking piece 52 is provided with a driven bevel gear meshed with the driving bevel gear, so that the rotating torque of the rotating operation piece can be reduced when the operation piece is screwed, labor is saved, and the user experience is improved. In an example of this embodiment, as shown in fig. 14 and 15, the driving bevel gear on the rotating member 531 is a pinion, and the driven bevel gear on the toggling member 52 is a gearwheel, that is, a bevel gear transmission mechanism in the form of a gearwheel driven by a pinion is used for acting force and reacting force at the gear engagement, and according to a torque calculation formula, the torque N1 is the acting force arm L1 at the engagement, and the torque N2 is the acting force arm L2 at the engagement, that is, the torque N1 is smaller than the torque N2. It can be understood that the torque N1 is equivalent to the rotating force of the operator for manually screwing the operating element 532, the torque N2 is equivalent to the tensile pulling force, the large gear is driven by the small gear for transmission, the rotating force of the manual screwing operating element 532 can be reduced, the labor is saved, the moving smoothness of the transmission mechanism is improved, and the user experience is improved. Wherein the moment arm L1 is the radius R2 of the center circle (dotted line circle in fig. 15) of the gear on the rotating piece; the toggle 52 pulls a circle (a dotted circle in fig. 14) formed around the center of the rotational axis of the toggle at a pulling action point with respect to the cord, and the arm L2 indicates a radius R1 of the circle.

In some exemplary embodiments, as shown in fig. 9, a shift lever 521 for shifting the pulling member 511 is protruded from the shifting member 52, and a guide slot 5211 or a guide hole for passing the pulling rope is opened on the shift lever 521. When the toggle piece 52 rotates, the guide groove 5211 or the guide hole on the toggle piece 521 plays a role in guiding the pull rope 51, so that the pull rope 51 is effectively prevented from shifting during movement, and the stability and reliability of the unlocking mechanism are improved.

In some exemplary embodiments, as shown in fig. 9 and 10, a first tooth groove 5212 is formed on the shift lever 521, and a second tooth groove 5111 matched with the first tooth groove 5212 is formed on an end surface of the pulling member 511, so that the friction force between the shift lever 521 and the pulling member 511 is enhanced, and the stability and reliability of the unlocking mechanism are improved.

It can be understood that the pulling member 511 is provided with a through hole 5112 for passing the pulling rope 51 and a locking hole 5113, and the locking hole 5113 cooperates with a screw to lock and fix the pulling member 511 on the pulling rope 51.

It is understood that the pulling action point between the pulling of the pulling member 52 and the pulling rope can be set on the end surface of the pulling member 511 engaged with the pulling lever 521.

In an example of this embodiment, as shown in fig. 7, when the operating member 532 is in an initial state (the locking member 31 locks the filter element 20, i.e., a locking position), an included angle a between a segment of the pulling rope 31 from an end fixed in the fixing hole of the pulling handle 311 to the through hole 5112 of the pulling member 511 and the shifting lever 521 is greater than or equal to 90 °, so that the shifting lever 521 is prevented from generating an upward pushing force on the pulling member 511 during pulling the pulling rope 51, and the pushing force may cause the pulling rope 51 to be disengaged from the guiding groove 5211 of the shifting lever 521, so that the purpose of rotating the locking member 31 to unlock the filter element by pulling the pulling rope 51 cannot be achieved.

In some exemplary embodiments, as shown in fig. 8, the rotating assembly 53 further includes an elastic member 54, and the elastic member 54 is configured to be compressed when the operating member 532 is screwed, and can push the operating member 532 to be reset by its own elastic force after the external force applied to the operating member 532 is stopped. After the operating piece 532 is screwed to unlock, the operating piece can be reset through the elastic piece 54, and the use convenience of the unlocking mechanism is improved.

Specifically, the rotating assembly 53 further includes a supporting member 55 fixedly connected to the bracket 40, one end of the operating member 532 sequentially penetrates through the opening formed in the first supporting plate 41, the mounting hole 551 formed in the supporting member 55 and is fixedly connected to the rotating member 531, the elastic member 54 is a spring, the spring is disposed in the mounting hole 551 and is fixed between the baffle 5321 formed on the operating member 532 and the bracket 40, the first blocking rib 5511 is disposed on the inner side wall of the mounting hole 551, the second blocking rib 5322 is disposed on the side wall of the operating member 532, and two ends of the spring respectively abut against the first blocking rib 5511 and the second blocking rib 5322. When the operating member 532 is screwed, the second stopper rib 5322 applies pressure to the spring, forcing the spring to compress toward the first stopper rib 5511; when the pressure on the spring is stopped, the spring can push the second rib 5322 to reset by using the self-elastic force. In one example of the present embodiment, as shown in fig. 8, the two springs are provided, and the operation member 532 is rotated left and right, so that the purpose of returning can be achieved. It should be noted that the two springs in fig. 8 are superimposed at their ends for the sake of illustration.
