For example, unless otherwise specified, the terms "installation," "connection," "joining," and "fixing" can specifically refer to any feasible connection form such as bolt connection, screw connection, welding, insertion, riveting, fusion welding, or snap-fit.

[0037] like Figure 1 As shown, in some embodiments of this utility model, the vacuum cleaner 100 includes a suction head 110, a suction pipe 120, a dust collector 130, a filter 140, and a vacuum blower 150. The vacuum blower 150 is used to drive air to flow sequentially through the suction head 110, the suction pipe 120, the dust collector 130, the filter 140, and the vacuum blower 150.

[0038] It should be noted that, although not explicitly shown in the figure, the vacuum cleaner 100 has an exhaust port on the side of the vacuum fan 150 away from the filter 140 to ensure that the vacuum fan 150 can drive air to flow sequentially through the nozzle 110, the vacuum pipe 120, the dust collector 130, the filter 140 and the vacuum fan 150.

[0039] Furthermore, the vacuum cleaner 100 also includes a blocking member 160 and a drive device 170, which is used to drive the blocking member 160 to control the opening and closing of the air passage between the vacuum pipe 120 and the dust collector 130.

[0040] In this invention, after the air passage between the suction pipe 120 and the dust collector 130 is blocked, the vacuum cleaner 100 can utilize the reverse rotation of the suction fan 150 or the base station 200 (such as...) Figure 2 The dust collection fan 220 (as shown) rotates inside Figure 2 As shown), air is driven from the filter 140 to the dust collector 130 to perform air washing on the filter 140. Therefore, this invention achieves automatic cleaning of the filter 140 of the vacuum cleaner 100, avoiding manual cleaning by the user and improving the user experience. This is especially true when the vacuum cleaner 100 is used in conjunction with the base station 200 (e.g., Figure 3 and Figure 4 As shown, foreign objects 300 (including dust, debris, etc.) washed off by the air on the filter 140 can directly enter the dust collection chamber 212 inside the base station 200, avoiding secondary pollution to the environment.

[0041] likeFigure 2 As shown, this utility model also provides a base station 200, which is adapted to the vacuum cleaner 100 of this utility model. Furthermore, the base station 200 includes a station body 210 and a dust collection fan 220.

[0042] The station body 210 is provided with a dust collection port 211 and a dust collection chamber 212 connected to the dust collection port 211. The dust collection port 211 is adapted to the dust collector 130 so that foreign objects 300 in the dust collector 130 can enter the dust collection chamber 212.

[0043] The dust collection fan 220 is used to drive air to flow sequentially through the filter 140, the dust collector 130 and the dust collection chamber 212 when the blocking member 160 blocks the air passage between the dust suction pipe 120 and the dust collector 130, thereby performing air washing on the filter 140.

[0044] like Figure 3 to Figure 8 As shown, the present invention also provides a cleaning device 001, which includes a vacuum cleaner 100 and a base station 200 of the present invention.

[0045] The following reference Figure 1 to Figure 8 The present invention will be further illustrated by examples of the vacuum cleaner 100 and the cleaning device 001. Figure 1 to Figure 4 The image shown is of a vacuum cleaner 100 and a cleaning device 001 according to the first embodiment of this utility model. Figure 5 and Figure 6 The image shown is of a vacuum cleaner 100 and a cleaning device 001 according to the second embodiment of this utility model. Figure 7 and Figure 8 The illustration shows a vacuum cleaner 100 and a cleaning device 001 in the third embodiment of the present invention.

[0046] like Figure 1 As shown, in the first embodiment of this utility model, the dust collector 130 is equipped with a dust collection cover 131 to open and close the dust collector 130. One end of the dust collector 130 with the dust collection cover 131 can be connected to the dust collection port 211 on the base station 200, and the dust collection cover 131 is inserted into the dust collection port 211.

[0047] like Figure 1 , Figure 3 and Figure 4 As shown, in the first embodiment of this utility model, the dust collector 130 is provided with a release button 132 for controlling the opening and closing of the dust collection cover 131. The release button 132 is triggered by the base station 200 when the dust collector 130 is connected to the dust collection port 211, thereby releasing the dust collection cover 131 and opening the dust collector 130.

[0048] Furthermore, although not explicitly shown in the figure, a locking spring is also provided on the dust collector 130 to provide a force to the release button 132 to lock the dust collection cover 131.

[0049] For example, the release button 132 is rotatably mounted on the dust collector 130, and a hook (not marked in the figure) is provided at one end of the release button 132 near the dust collection cover 131. The hook and the locking spring are located on opposite sides of the rotation axis of the release button 132.

[0050] When the dust collector 130 is connected to the dust collection port 211 of the base station 200, the end of the dust collector 130 with the dust collection cover 131 is inserted into the base station 200, thereby causing the side wall of the dust collection port 211 to abut against the release button 132 and compress the locking spring to release the dust collection cover 131, so that the dust collection cover 131 opens the dust collector 130.

[0051] To ensure that the base station 200 can force the release button 132 to release the dust collection cover 131, those skilled in the art can also, as needed, provide a boss on the side of the release button 132 away from the locking spring. The side of the boss facing the base station 200 can be set as an inclined surface to ensure that the boss can slide into the dust collection port 211 and be squeezed by the base station 200, thereby driving the release button 132 to rotate.

[0052] like Figure 1 As shown, in the first embodiment of this utility model, the suction pipe 120 includes an axial pipe section 121 and a radial pipe section 122, and the suction pipe 120 is connected to the dust collector 130 through the radial pipe section 122. Furthermore, a blocking member 160 is movably disposed along the axial pipe section 121 at one end of the axial pipe section 121 near the radial pipe section 122, and the blocking member 160 can move into and out of the radial pipe section 122 to control the opening and closing of the radial pipe section 122 (e.g., ...). Figure 1 , Figure 3 and Figure 4 (As shown).

[0053] Furthermore, the blocking member 160 and the axial pipe segment 121 can be slidably connected. This slidable connection can be a direct slidable connection or an indirect slidable connection.

[0054] For example, in a direct sliding connection, the axial pipe section 121 is provided with a slot or groove, and the blocking member 160 is inserted into the slot or groove and can slide relative to the axial pipe section 121.

[0055] As an example of an indirect sliding connection, the blocking member 160 is slidably connected to other components on the vacuum cleaner 100 (e.g., the housing at the handheld end) so that the blocking member 160 is indirectly slidable relative to the axial tube segment 121 through the sliding connection between the blocking member 160 and the other components.

[0056] Further, the blocking member 160 can be provided as a plate structure to make the structure of the blocking member 160 simpler and lighter, thereby reducing the production cost of the blocking member 160 and improving the response frequency of the blocking member 160, on the basis of ensuring that the blocking member 160 can block the air path between the dust suction pipeline 120 and the dust collector 130.

[0057] As shown in Figure 1 , in the first embodiment of the utility model, the blocking member 160 comprises a rack 161.

[0058] Continuing to refer to Figure 1 , in the first embodiment of the utility model, the driving device 170 is installed on the axial pipe section 121. And the driving device 170 comprises a gear 171 engaged with the rack 161 and a motor 172 drivingly connected with the gear 171, to realize the control of the blocking member 160 on the air path on-off between the dust suction pipeline 120 and the dust collector 130 through the forward rotation and reverse rotation of the motor 172.

[0059] Exemplarily, the motor 172 is fixedly connected with the dust suction pipeline 120 through its casing (for example, screw connection between the two), and is coaxially fixedly connected with the gear 171 through its rotating shaft (for example, the two are inserted together in the form of interference fit).

[0060] As shown in Figure 1 , Figure 3 and Figure 4 , in the first embodiment of the utility model, the dust collector 100 further comprises a handle 180 for hand holding, and the handle 180, the dust collector 130, the filter 140 and the dust suction fan 150 are all arranged at one end of the dust suction pipeline 120. That is, the dust collector 100 in the first embodiment of the utility model can be a handheld dust collector 100.

[0061] The cooperation use method and working principle of the dust collector 100 and the base station 200 in the first embodiment of the utility model will be briefly explained below with reference to Figure 3 and Figure 4 .

[0062] When it is needed to dump the foreign matter 300 in the dust collector 130, the dust collector 130 is inserted into the dust collecting port 211 of the base station 200 to fix the dust collector 100 to the base station 200. In this process, the release button 132 is triggered by the base station 200 to release the dust collecting cover 131, so that the foreign matter 300 in the dust collector 130 falls into the dust collecting cavity 212.

[0063] Then, the dust collecting fan 220 is started to make the air along Figure 3The residual foreign matter 300 in the dust collector 130 and the dust suction pipeline 120 is sucked into the dust collection cavity 212 along the path indicated by the dotted arrow.

[0064] Subsequently, the motor 172 of the driving device 170 is rotated in the forward direction, so that the rack 161 drives the blocking member 160 to move into the radial pipe section 122, blocks the air path in the radial pipe section 122, and further makes the air flow along the air path in the radial pipe section 122. Figure 4 The residual foreign matter 300 in the dust collector 130 and the dust suction pipeline 120 is sucked into the dust collection cavity 212 along the path indicated by the dotted arrow.

[0065] Finally, after the cleaning of the filter 140 is completed, the motor 172 of the driving device 170 is reversed, so that the rack 161 drives the blocking member 160 to move out of the radial pipe section 122 (as shown in Figure 1 and Figure 3 ).

[0066] In addition, in the open outdoor, the cleaning of the filter 140 can also be realized without the base station 200 by controlling the dust suction fan 150 to be reversed to force the air to flow through the filter 140 and the dust collector 130 in sequence.

[0069] Exemplarily, a sliding guide structure is arranged on or installed on the dust suction pipeline 120, so that the dust suction pipeline 120 is slidingly connected with the blocking member 160 through the sliding guide structure. The sliding guide structure can be an arc-shaped groove arranged on the dust suction pipeline 120, or an arc-shaped guide rail installed on the dust suction pipeline 120, or any other feasible member.

Correspondingly, the driving device 170 is installed on the suction head 110.

[0077] It should be noted that although Figure 3 to Figure 8 does not show the motor 172, the driving device 170 in the first embodiment to the third embodiment of the utility model all has the motor 172.
