[0064] Based on the second embodiment, the present invention further provides a fifth embodiment of a method, which includes the following steps:

[0065] S1: First, place the dust removal device 200 vertically downward into the base station cavity 120;

[0066] S2: The first driving arm 350 is then pushed upward by the first push rod 160 until the engagement arm 330 rotates downward by an angle greater than 20 degrees, and the engagement arm 330 does not interfere with the path of rotation of one end of the second bottom cover 400 around the axis;

[0067] S3: The second driving arm 420 then comes into contact with the second push rod 180;

[0068] S4: Then the second driving arm 420 continues to be pushed upward by the second push rod 180, and one end of the second bottom cover 400 is rotated open to ensure that at least part of the dust in the primary dust collecting chamber 250 or the secondary dust collecting chamber 620 falls into the base station dust collecting chamber 140 until the first stage ends.

[0069] The above four steps are for installing the vacuum cleaner on the base station 100. Before the vacuum cleaner is installed on the base station 100, the second bottom cover 400 is attached to the first bottom cover 300 by the torsional force of the second torsion spring 460. To increase the adhesion of the second bottom cover, the torsional force of the first torsion spring 390 is used to press the second bottom cover 400, making the second bottom cover 400 more secure.

[0070] This embodiment also includes a second stage of dust cleaning, which specifically includes the following steps:

[0071] S5: After the motor of the base station 100 starts working, the remaining dust in the primary dust collecting chamber 250 or the secondary dust collecting chamber 620 falls into the base station dust collecting cavity 140;

[0072] S6: After the motor of the base station 100 stops working, one end of the second bottom cover 400 recovers its deformation and moves upward under the action of the second torsion spring 460;

[0073] S7: The dust removal device 200 is then moved vertically upward out of the base station cavity 120;

[0074] S8: Then the second push rod 180 is disengaged from the second driving arm 420, and one end of the second bottom cover 400 is rotated in the opposite direction to close the bottom cover through hole 320;

[0075] S9: The first push rod 160 then disengages from the first drive arm 350 until one end of the second bottom cover 400 is pushed upward by the engagement arm 330. The rotational path of the engagement arm 330 and the second bottom cover 400 intersect, and due to the height differences between the first push rod 160 and the second push rod 180, the second bottom cover 400 remains above the engagement arm 330 before the intersect. Furthermore, the outer layer of the first rotating shaft 370 is provided with a rubber coating 375. The rubber coating 375 creates a certain frictional force when in contact with the inner wall of the first bottom cover 300, slowing the rotation of the engagement arm 330 and ensuring that the second bottom cover 400 closes before the engagement arm 330 returns to its original position.

[0076] Therefore, when the handheld vacuum cleaner is mounted on the base station 100, the first push rod 160 on the base station pushes the first drive arm 350 to rotate about the first rotation axis 370, thereby unlocking the second bottom cover 400. The second bottom cover 400 is mounted below the first bottom cover 300 via the second rotation axis 440 and the second torsion spring 460. When the base station's motor is powered on, a certain negative pressure is generated. When the force of the negative pressure acting on the second bottom cover 400 exceeds the torque of the second torsion spring 460, the second bottom cover 400 rotates open about the second rotation axis 440, and dust in the vacuum cleaner's dust removal device 200 is sucked into the dust bag inside the base station. When the base station 100 is stopped and there is no negative pressure, the second bottom cover 400 rotates about the rotation axis due to the torque of the second torsion spring 460, attaching to the first bottom cover 300. When the handheld vacuum cleaner is removed from the base station 100, the engagement arm 330 locks one end of the second bottom cover 400 to prevent it from accidentally opening due to excessive dust. That is, the two push rods on the base station 100 successively contact the first and second driving arms 350 and 440 to clean dust from the dust removal device 200 of the vacuum cleaner. In summary, the base station 100 of this embodiment opens the second bottom cover 400 to clean dust from the inside of the handheld vacuum cleaner. When the second bottom cover 400 is closed, the engaging arms 330 press the second bottom cover 400 upward, ensuring the reliability of the second bottom cover 400 in the closed state. This reduces structural costs and improves the user experience for consumers.

[0083] S600: Continue to move the dust removal device 2000 vertically upward out of the base station cavity 1200;

[0084] S700: Finally, the trigger driving arm 4560 is released from the pressure of the ejector pin 1600, until the trigger engaging arm 4540 is restored to abut against one end of the second bottom cover 4000.
