[0046] As Figures 1 to 14 shown in the utility model, the cleaning device 001 includes a dust collector 100 and a base station 200.

[0047] The dust collector 100 includes a dust suction pipeline 110, a dust collector 120, a filter 130, and a dust suction fan 140. The dust suction fan 140 is configured to drive air to flow through the dust suction pipeline 110, the dust collector 120, the filter 130, and the dust suction fan 140 in sequence. The dust collector 120 is provided with a dust collection cover 121 to open and close the dust collector 120. The dust collector 100 further includes an air path blocking device 150 for controlling the air path between the dust suction pipeline 110 and the dust collector 120.

[0048] It should be noted that although it is not explicitly shown in the figure, the dust collector 100 is provided with an exhaust port on the side away from the filter 130 to ensure that the dust suction fan 140 can drive air to flow through the dust suction pipeline 110, the dust collector 120, the filter 130, and the dust suction fan 140 in sequence.

[0049] The base station 200 includes a station body 210, a driving device 220, and a dust collection fan 230. The station body 210 is provided with a dust collection port 211 and a dust collection cavity 212 communicating with the dust collection port 211. The dust collection port 211 is adapted to the dust collector 120, so that when the dust collector 120 is connected to the dust collection port 211 and the dust collection cover 121 is opened, the foreign matter 300 (including dust, debris, etc.) in the dust collector 120 enters the dust collection cavity 212. The driving device 220 is configured to drive the air path blocking device 150 to block the air path between the dust suction pipeline 110 and the dust collector 120, so that the dust collection fan 230 drives air to flow through the filter 130, the dust collector 120, and the dust collection cavity 212 in sequence, and the filter 130 is air washed.

[0050] The utility model discloses a dust collector 100 is arranged on the air path blocking device 150 for controlling the air path between the dust suction pipeline 110 and the dust collector 120, and the driving device 220 for driving the air path blocking device 150 is arranged on the base station 200, so that after the dust collector 100 is placed on the base station 200, the air path blocking device 150 can be blocked between the dust suction pipeline 110 and the dust collector 120 by the driving device 220, and then the dust collection fan 230 drives air to flow through the filter 130, the dust collector 120, and the dust collection cavity 212 in sequence, and the filter 130 is air washed. Therefore, the utility model realizes the automatic cleaning of the filter 130 of the dust collector 100, avoids manual cleaning, and improves the user's experience. At the same time, after the foreign matter 300 (including dust, debris, etc.) on the filter 130 is washed down by air, it can directly enter the dust collection cavity 212 in the base station 200, avoiding secondary pollution to the environment.

[0051] Further, the skilled in the art can set a filtering device (for example, filter cotton) between the dust suction fan 140 and the air outlet according to the need to perform secondary filtering on the discharged air to prevent secondary pollution to the environment. In this way, when the filter 130 is air washed, the air will also flow through the filtering device, so that the filtering device is also air washed.

[0052] The cleaning device 001 of the present application will be further illustrated below with reference to Figures 1 to 14 . Among them, Figures 1 to 6 shown is the cleaning device 001 in the first embodiment of the present application, Figures 7 to 10 shown is the cleaning device 001 in the second embodiment of the present application, Figures 11 to 14 shown is the cleaning device 001 in the third embodiment of the present application.

[0053] As Figure 1 shown, in the first embodiment of the present application, the dust collector 100 further comprises a handle 160 for hand holding, the handle 160, the dust collector 120, the filter 130 and the dust suction fan 140 are all arranged at one end of the dust suction pipeline 110. Moreover, the dust collector 100 further comprises a suction head 170 located at the other end of the dust suction pipeline 110, and a part of the dust suction pipeline 110 is formed on the suction head 170. That is, the dust suction pipeline 110 comprises the part formed on the suction head 170 and the pipeline connecting the suction head 170 and the dust collector 120. The pipeline is in sealing connection with the suction head 170.

[0054] That is, the dust collector 100 in the first embodiment of the present application can be a handheld dust collector.

[0055] As Figure 1 shown, in the first embodiment of the present application, the air path blocking device 150 is arranged between the dust suction pipeline 110 and the dust collector 120. That is, the air path blocking device 150 is arranged at the hand holding end of the handheld dust collector.

[0056] Continuing to refer to Figure 1 , the air path blocking device 150 comprises a sliding piece 151 in sliding connection with the dust suction pipeline 110 and / or the dust collector 120, so that the sliding piece 151 moves to a position (for example, as Figure 1 , Figure 3 and Figure 4 ) in which the dust suction pipeline 110 and the dust collector 120 are in communication by sliding, and moves to a position (for example, as Figure 5 and Figure 6 ) in which the dust suction pipeline 110 and the dust collector 120 are blocked from communication.

[0057] Among them, the sliding piece 151 can be in a sheet structure.

[0058] It should be noted that the sliding connection between the sliding member 151 and the dust suction pipeline 110 and / or the dust collector 120 can be a direct sliding connection or an indirect sliding connection.

[0059] For example, the direct sliding connection is that the dust suction pipeline 110 is provided with a slot or a sliding groove, and the sliding member 151 is inserted into the slot or the sliding groove and is slidable relative to the dust suction pipeline 110.

[0060] For example, the indirect sliding connection is that the sliding member 151 is in sliding connection with other components (for example, the shell at the handheld end) of the dust collector 100, so as to indirectly make the sliding member 151 slidable relative to the dust suction pipeline 110 and / or the dust collector 120 through the sliding connection between the sliding member 151 and the other components.

[0061] As shown in Figure 4 and Figure 6 , in the first embodiment of the utility model, the air path blocking device 150 further includes a reset spring 152, and the reset spring 152 is used for restoring and keeping the air path blocking device 150 at a position (as shown in Figure 4 ) in which the dust suction pipeline 110 and the dust collector 120 are in communication.

[0062] As shown in Figure 2 , in the first embodiment of the utility model, the driving device 220 is arranged at the top of the station body 210 and includes a rack 221 in sliding connection with the station body 210, a gear 222 in meshing connection with the rack 221, and a motor 223 in driving connection with the gear 222.

[0063] For example, the motor 223 is fixed to the station body 210, and the rotating shaft of the motor 223 is coaxially fixedly connected with the gear 222.

[0064] As can be seen from Figures 2 to 6 , in the first embodiment of the utility model, the rack 221 is arranged to slide in the vertical direction.

[0065] As shown in Figures 3 to 6 , in the first embodiment of the utility model, the motor 223 can drive the gear 222 to rotate when the motor 223 rotates, and the rack 221 moves up and down by means of the meshing between the rack 221 and the gear 222.

[0066] When the rack 221 moves upward, the rack 221 drives the sliding member 151 to move upward from the position shown in Figure 3 and Figure 4 to the position shown in Figure 5 and Figure 6 , and thus the sliding member 151 blocks the communication between the dust suction pipeline 110 and the dust collector 120.

[0067] When the rack 221 moves downward, the slider 151 moves downward under the action of the return spring 152, from the position shown in Figure 5 and Figure 6 to the position shown in Figure 3 and Figure 4 , and thus makes the dust suction pipeline 110 communicate with the dust collector 120.

[0068] In addition, under the premise that the rack 221 can drive the slider 151 to move, the person skilled in the art can also make the rack 221 slide in other directions as needed.

[0069] In addition, under the premise that the slider 151 moves from the position shown in Figure 5 and Figure 6 to the position shown in Figure 3 and Figure 4 , the person skilled in the art can also omit the setting of the return spring 152 as needed. For example, a magnet is fixed on at least one of the slider 151 and the rack 221, so that the slider 151 and the rack 221 are magnetically connected, so that when the rack 221 moves downward, the slider 151 can be pulled downward by the magnetic force. At the same time, it also ensures that the dust collector 100 and the base station 200 can be normally separated.

[0070] As shown in Figure 1 , Figures 3 to 6 , in some embodiments of the utility model, the dust collector 120 is provided with a release button 122 for controlling the opening and closing of the dust cover 121. The release button 122 is triggered by the base station 200 when the dust collector 120 is connected with the dust collecting port 211, and thus releases the dust cover 121, so that the dust cover 121 opens the dust collector 120.

[0071] As shown in Figure 4 and Figure 6 , the dust collector 120 is also provided with a locking spring 123 to provide the release button 122 with a force for locking the dust cover 121.

[0072] Exemplarily, the release button 122 is installed on the dust collector 120 in a rotating manner, and one end of the release button 122 close to the dust cover 121 is provided with a hook (not marked in the figure), which is located on the opposite side of the rotation axis of the release button 122 from the locking spring 123.

[0073] When the dust collector 120 is connected with the dust collecting port 211 of the base station 200, the end of the dust collector 120 provided with the dust cover 121 is inserted into the base station 200, and thus the side wall of the dust collecting port 211 abuts against the release button 122 and presses the locking spring 123, so as to release the dust cover 121 and make the dust cover 121 open the dust collector 120.

[0074] In order to ensure that the base station 200 can force the release button 122 to release the dust collecting cover 121, a skilled person in the art can set a protrusion on the side of the release button 122 away from the locking spring 123 according to the need. The side of the protrusion facing the base station 200 can be set as an inclined surface to ensure that the protrusion can slide into the dust collecting port 211 and be extruded by the base station 200, thereby driving the release button 122 to rotate.

[0075] A skilled person in the art can understand that, in the first embodiment of the utility model, on the basis of ensuring that the air path blocking device 150 on the dust collector 100 is driven by the driving device 220 on the base station 200 and thus controls the air path on-off between the dust collecting pipeline 110 and the dust collector 120, by setting the air path blocking device 150 as the sliding piece 151 between the dust collecting pipeline 110 and the dust collector 120, the structure of the dust collector 100 is more compact, and the air path blocking device 150 is effectively prevented from protruding too much and affecting the aesthetics of the dust collector 100.

[0076] The cooperation 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 Figures 3 to 6

[0077] When it is needed to dump the foreign matter 300 in the dust collector 120, the dust collector 120 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 122 is triggered by the base station 200 to release the dust collecting cover 121, so that the foreign matter 300 in the dust collector 120 falls into the dust collecting cavity 212.

[0078] Then, the dust collecting fan 230 is started to make air flow along the path shown by the dotted arrow in the figure, sucking the residual foreign matter 300 in the dust collector 120 and the dust collecting pipeline 110 into the dust collecting cavity 212. Figure 3

[0079] Subsequently, the motor 223 of the driving device 220 rotates to make the rack 221 push the sliding piece 151 to move upward and block the air path between the dust collecting pipeline 110 and the dust collector 120, so that air flows along the path shown by the dotted arrow in the figure, sequentially passing through the filter 130, the dust collector 120 and the dust collecting cavity 212 to wash the filter 130. Figure 5

[0080] The cooperation 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 Figures 7 to 10 ​​​The second embodiment of the utility model will be described in detail. Before that, it needs to be explained that in order to facilitate the description, and in order to enable the person skilled in the art to quickly understand the technical scheme of the utility model, the differences between the second embodiment and the first embodiment in the preceding text will be described in detail in the following text. For the same parts of the second embodiment and the first embodiment in the preceding text, the person skilled in the art can refer to the description in the first embodiment in the preceding text.

[0081] As Figure 7 , Figure 9 and Figure 10 indicated, in the second embodiment of the utility model, the air path blocking device 150 is arranged on the dust suction pipeline 110, and is arranged at one end of the dust suction pipeline 110 close to the dust collector 120.

[0082] Continuing to refer to Figure 7 , Figure 9 and Figure 10 , the air path blocking device 150 comprises a rotating piece 153 rotatably connected with the dust suction pipeline 110, so that the rotating piece 153 moves to a position of opening or blocking the dust suction pipeline 110 in a rotating manner.

[0083] As Figure 7 indicated, in the second embodiment of the utility model, the rotating piece 153 comprises a switch part 1531 located inside the dust suction pipeline 110 and a driving part 1532 located outside the dust suction pipeline 110, and the driving part 1532 is used to drive the rotating piece 153 to rotate, so as to make the switch part 1531 open or block the dust suction pipeline 110.

[0084] As Figure 8 indicated, the driving device 220 in the second embodiment of the utility model is appropriately lowered compared with the position of the driving device 220 in the first embodiment, so as to adapt to the position of the air path blocking device 150.

[0085] As Figure 9 and Figure 10 indicated, in the second embodiment of the utility model, the driving part 1532 is matched with the rack 221 of the air path blocking device 150, so that the rack 221 abuts against the driving part 1532 and drives the rotating piece 153 to rotate.

[0086] As Figure 7 , Figure 9 and Figure 10 can be seen, the rotating piece 153 can open the dust suction pipeline 110 in the direction of the air flow in the dust suction pipeline 110 towards the dust collector 120, so that the rotating piece 153 can automatically open the dust suction pipeline 110 when the dust suction fan 140 rotates. Therefore, the dust collector 100 in the second embodiment of the utility model can not be configured with a reset spring 152 for the rotating piece 153.

[0087] AsFigures 11 to 14 As shown, in the third embodiment shown, unlike the second embodiment above, the air path blocking device 150 is arranged at the end of the dust suction pipeline 110 away from the dust collector 120, and specifically can be arranged on the suction head 170. At the same time, the position of the driving device 220 on the base station 200 is also adjusted accordingly.

[0088] It should be noted that although Figures 3 to 14 The motor is not shown in the first embodiment to the third embodiment, but the driving device 220 in the first embodiment to the third embodiment all has a motor 223.

[0089] In addition, in other embodiments of the present application, those skilled in the art can set the air path blocking device 150 at any position on the dust suction pipeline 110 as needed, for example, at the middle section of the dust suction pipeline 110.

[0090] So far, the technical scheme of the present application has been described in combination with the above embodiments, but those skilled in the art can easily understand that the protection scope of the present application is not limited to these specific embodiments. Without deviating from the technical principles of the present application, those skilled in the art can split and combine the technical schemes in the above embodiments, or make equivalent changes or replacements to related technical features, and any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the present application will fall within the protection scope of the present application.

[0091] Finally, it should be noted that in the present application, the term "communication" means fluid communication to allow fluid (such as air, liquid) to flow between two things in communication with each other.
