In one embodiment, as shown in FIG. 18, the volute 947 and the slider housing 957 are removed to facilitate viewing of the motion conversion mechanism of the present application. The worm gear mechanism 94 includes a worm 941 sleeved on the output shaft of the motor and a worm gear 943 driven by the worm 941. The worm gear mechanism 94 converts the rotation of the motor 93 around the first direction into a worm gear Rotation of 943 around the third direction. The third direction is perpendicular to the first direction.

Continuing to refer to FIG. 19, the crank-slider mechanism 95 includes a crank 950, a slider 953, and a connecting rod 951 connecting the crank 950 and the slider 953. One end of the crank 950 is fixedly connected to the output shaft of the worm gear 943, and the other end is connected to the connecting rod 951. The rod 951 is pivotally connected, the slider is movably arranged on the slide rail along the second direction, and the crank-slider mechanism 95 converts the rotation of the worm wheel 943 in the third direction into the slider 953 Reciprocating motion in the second direction. The second direction is perpendicular to the third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

The crank 950 is sleeved on the end of the output shaft of the worm gear (not shown), and realizes a non-rotatable fixed connection to facilitate transmission. The rotation of the worm gear 943 drives the crank 950 to rotate. Further, the connecting rod 951 is pivotally connected to the crank 950 through the fixing pin 945. The rotation of the crank 950 drives the end of the connecting rod 951 to rotate around the output shaft of the worm gear 943, and the movement of the connecting rod 951 around the axis makes the connecting rod 951 rotate. The sliding block 953 reciprocates along the second direction, and the reciprocating motion of the sliding block 953 causes the sealing member 923 linked with it to vibrate back and forth, thereby shaking off the dust located at the connection between the dust extraction port and the dust extraction channel, preventing clogging and reducing the Dust extraction efficiency.

Wherein, the crank-slider mechanism 95 further includes a slide rail 955 that is movably cooperated with the slide block 953, and the slide rail 955 is arranged along the second direction to limit the movement of the slide block 953 along the first direction .

The shape of the extension arm 959 matches the outer shape of the seal 923 . In this embodiment, the sealing member 923 is C-shaped with a half-frame, correspondingly, the extension arm 959 is also set to match the shape of the half-frame, and the receiving surface is provided with a corresponding slope or chamfer.

Referring to Fig. 19 and Fig. 20, there are respectively two working states of the anti-blocking device. In the first state shown in Fig. 19, the crank 950 rotates around the pivot axis of the worm gear and is in the middle position relative to the rotation axis of the worm gear. When the extension arm 959 is at a certain distance from the seal 923, the seal 923 is in a normal state.

Continue to refer to FIG. 20, which is the second state of the anti-blocking device. At this time, the crank 950 continues to rotate around the output shaft of the worm gear to the highest position relative to the first state, that is, the other end of the crank 950 is above the output shaft of the worm gear. When the slider 953 moves toward the direction close to the volute 947 to the limit position in the second direction, the extension arm 959 is embedded in the groove of the seal 923, pushing the seal 923 to move in the same direction, mainly to make the contact with the extension arm 959 The grooves are deformed to disperse nearby dust and enter the dust extraction channel with the airflow.

Of course, the work of the anti-blocking device is continuous. In other states, the crank 950 can also rotate from the highest point to the lowest point relative to the second state, that is, the other end of the crank 950 is below the output shaft of the worm gear. At this time, the slider 953 Moving in the direction away from the volute 947 to another extreme position in the second direction, the extension arm 959 disengages from the groove of the seal 923, so that the seal 923 returns to the original position under the action of the elastic restoring force. In a word, the sealing member 923 is actively moved in the second direction under the driving of the anti-blocking device, or returns to the initial state under the action of the elastic restoring force. Such repeated regular vibration enhances the fluidity near the dust extraction port 922, effectively Dust accumulation is avoided.

To sum up, the anti-blocking device provided by the present application drives the motion conversion mechanism to move through the motor 93, so that the seal 923 vibrates regularly to shake off the dust and prevent the dust from blocking the dust extraction port 922, and the movement is sweeping the floor. The robot 96 enters the maintenance station 9100 and starts the dust extraction operation, which is almost synchronized with the dust extraction operation and stops at the same time. Therefore, the operation is intelligent and a good anti-clogging effect can be achieved.
