FIG. 13 is an enlarged cross-sectional view illustrating a state in which a push rod of a docking station of a cleaning device presses a cover of a vacuum cleaner according to an embodiment of the disclosure. FIG. 14 is an enlarged cross-sectional view illustrating a state in which a push rod of a docking station of a cleaning device releases pressure on a cover of a vacuum cleaner according to an embodiment of the disclosure.

Referring FIGS. 13 and 14, the operation of the push rod 134 when a signal is applied to the switch 129 will be described.

As shown in FIG. 13, when a dust discharge signal is not applied to the switch 129, the rod driving portion 130 does not operate. That the rod driving portion 130 does not operate means a state in which the push rod 134 is inserted into the duct 123 by the connecting rod 133.

The user may input a dust discharge signal through the switch 129.

In this case, the pressing portion 134a of the push rod 134 is pressing the cover 11 of the dust collector 10. When the dust collector 10 of the vacuum cleaner 1 is mounted on the docking station 2, the cover 11 provided to open and close the dust collector 10 may be opened at any time.

In other words, when the vacuum cleaner 1 is not mounted on the docking station 2, an interference member (not shown) may interfere with the cover 11 of the dust collector 10 so that the cover 11 does not rotate.

However, when the vacuum cleaner 1 is mounted on the docking station 2, the interference portion 134b may be pressed so as not to interfere with the cover 11 any more. The interference portion 134b may be provided to be connected to a member having elasticity, but the concept is not limited thereto.

Therefore, as shown in FIG. 13, when the push rod 134 presses a portion of the cover 11, the cover 11 maintains the dust collector 10 in a closed state.

In addition, when a dust discharge signal is not applied to the switch 129, the driving device 13 of the suction portion 150 also does not operate. That is, the switch 129 may be provided to transmit an operation signal to the rod driving motor 132 and the driving device 153.

Therefore, in this case, the dust discharge operation of the dust collector 10 is not performed.

As shown in FIG. 14, when a dust discharge signal is applied to the switch 129, the rod driving portion 130 operates. More specifically, the rod driving motor 132 may operate.

When the rod driving motor 132 operates, the connecting rod 133 may rotate. The connecting rod 133 may rotate from a state of lying horizontally with respect to the ground to a state of being erected vertically with respect to the ground. Through this, the protrusions 133b of the connecting rod 133 may press the interference portion 134b of the push rod 134 downward. Thus, the push rod 134 descends.

As the push rod 134 descends, the pressure applied to the cover 11 of the dust collector 10 may be released. Thus, the cover 11 of the dust collector 10 may be opened.

In addition, when a dust discharge signal is applied to the switch 129, the driving device 153 of the suction portion 150 may be operated. Therefore, the foreign substances collected in the dust collector 10 may be suctioned toward the collecting portion 140. That is, foreign substances inside the dust collector 10 may pass through the duct portion 120 and move to the collection portion 140 to be collected in the dust bag 146.

Therefore, regardless of whether the vacuum cleaner 1 is mounted and charged, the user may determine whether to perform the dust collecting operation of the dust collector 10 according to the user's intention.

Through this, undesired noise that may occur when dust is discharged may be prevented, and convenience of the use may be improved.

In addition, since the docking station 2 of the cleaning device according to an embodiment of the present disclosure is provided with a recessed portion for accommodating the extension pipe 12 of the vacuum cleaner 1, and an accommodation space for accommodating the suction nozzle 13 is formed at the bottom thereof, the vacuum cleaner 1 may be docked more compactly.

Through this, the space occupied by the cleaning device may be minimized, and thus the appearance aesthetics may be improved.

In addition, since the dust collector 10 of the vacuum cleaner 1 does not need to be separately docked onto the docking station 2, the convenience of the user may be increased.

In the above, specific embodiments have been illustrated and described. However, it is not limited to the above-described embodiments, and those skilled in the art will be able to make various changes without departing from the gist of the technical concept of the disclosure described in the claims below.

By allowing the vacuum cleaner to be charged simultaneously with being docked onto the docking station, the inconvenience of separately charging the vacuum cleaner can be reduced.

By discharging foreign substances in the dust collector of the vacuum cleaner only when a dust discharge signal is input to the docking station by the user, undesired noise generated when dust is discharged can be prevented.

By providing the docking station and the vacuum cleaner mounted on the docking station to be rotatable with respect to the ground, it is possible to improve external aesthetics and increase user convenience when the vacuum cleaner is not in use.
