The locking member 680 is an elastically deformable member that is locked with the dust cup lock hook 265 through the mating surface 267. The elastic member 690 is preferably a torsion spring that can reciprocate along the shaft 670 and provide sliding elastic force.

[0069] During operation, when the dust cup 200 is pushed in and the dust cup 200 has not yet contacted the actuating part 640, the actuating part 640 is in the initial position, as shown in Figure 3, and the locking part 680 is in the V state of Figure 13; the dust cup 200 contacts the actuating part 640, the wrench part 620 will rotate counterclockwise, and the locking part 680 will move in the direction of the arrow, as shown in the W state of Figure 14; when the dust cup 200 is pushed in with force, the improved dust cup unlocking device 600 will return to its original position under the spring action of the elastic part 690, and the locking part 680 will enter the recess 264 and lock with the dust cup lock hook 265 to lock the dust cup 200. At this time, the elastic part 690 acts as both a torsion spring and a spring to ensure that the improved dust cup unlocking device 600 is reset left and right, as shown in the X state in Figure 12. In the initial state, the locking part 680 presses against the dust cup 200 to prevent it from falling off; when the wrench part 620 is pressed down at an acute angle, the actuating part 640 applies force to the unlocking rod 700, and the unlocking rod 700 touches the dust cup cover 240, and the dust cup cover 240 will open for dumping dust, as shown in Figure 6; when the wrench part 620 is pressed to the bottom, the head of the actuating part 640 will apply force to the dust cup 200, causing the dust cup 200 to move forward, and then the dust cup 200 is manually removed, as shown in Figure 8.
