Description

Technical Field

[0001] The utility model relates to a cleaning device, in particular to a dust collecting device. Background Art

[0002] As a kind of smart cleaning appliance, handheld vacuum cleaners are increasingly entering thousands of households due to their small size and portability. Handheld vacuum cleaners generally use the negative pressure generated by the negative pressure motor to absorb garbage and other impurities into the dust cup for collection. After use, the dust cup is opened to dump the garbage. With the development of technology, handheld vacuum cleaners are equipped with a base station with dust collection and charging functions. The base station provides an installation position for the handheld vacuum cleaner. After use, the handheld vacuum cleaner is placed on the base station. The base station can charge and collect dust for the handheld vacuum cleaner. There is no need to manually open the dust bucket to dump garbage, which further frees your hands and improves the user experience of the handheld vacuum cleaner.

[0003] When the handheld vacuum cleaner is placed on the base station, the dust cup is placed above the dust storage chamber in the base station. When the base station collects the garbage in the handheld vacuum cleaner, first, the bottom cover buckled on the dust cup is opened by the cover opening assembly on the base station, and then the negative pressure motor located downstream of the dust storage chamber is turned on to guide the garbage in the dust cup into the dust storage chamber, so as to complete the cleaning of the dirt in the dust cup.

[0004] In the dust cup of the existing handheld vacuum cleaner, a filter assembly is located inside the dust cup, which is used to perform the first separation and filtration on the dust-containing fluid introduced into the dust cup, thereby completing the separation of flocculent dirt and gas in the dust-containing fluid.

[0005] However, since the solid dirt includes flocculent dirt such as hair, it is easy to adhere to the outer wall of the filter cover and cover the filter holes on the filter cover after contacting the filter cover. When the volume of the flocculent dirt is large, the filter holes of the filter assembly will be blocked, affecting the filtering effect of the filter assembly. Utility Model Content

[0097] Specifically, the shielding assembly is connected to the matching piece through the first spring 602. When the shielding assembly is located at the first position in the middle area 5, the first spring 602 is extended to the first state, the shielding assembly is located away from the matching piece, and blocks the first air guide port 5041. The rear end face of the shielding assembly forms a part of the outer shell of the vacuum cleaner.

When the moving block 6 is in the first position, the edge of the auxiliary plate 603 cooperates with the edge of the middle area 5 to limit the moving block 6 to the first position of the middle area 5. At this time, the bottom end face of the auxiliary plate 603 blocks the first air guide port 5041. When the moving block 6 is in the second position, the bottom end face of the auxiliary plate 603 blocks the second air guide port 5042.

The first air guide port 5041 and the second air guide port 5042 are both formed on the first bottom plate 504.

[0109] Furthermore, the first air guide port 5041 is an inclined structure, including a guide plate 50411 extending toward the air outlet end of the filter assembly 104 , and the external fluid is guided to the interior of the filter assembly 104 via the guide plate 50411 .

[0110] Furthermore, an auxiliary through hole is provided on the second side plate 505, and the auxiliary through hole corresponds to the second fluid inlet 506 and the through hole on the moving block 6. When the moving block 6 is in the first position and the second cover 107 is in the first position, the outer wall of the second cover 107 and the auxiliary plate 603 are both located inside the auxiliary through hole to form a part of the wall of the outer shell of the vacuum cleaner.

[0111] The structure of the base station in this embodiment is relative to that of the base station in the first embodiment, and further includes a second self-cleaning air duct, an air guide assembly, and a lower air guide pipe.

The driving component includes a driving motor 410 and a transmission gear 4101 sleeved on its output shaft.

[0114] The driving motor 410 is located below the air guide component 405, a portion of the transmission gear 4101 is located between the first air inlet channel 4051 and the second air inlet channel 4052, another portion of the transmission gear 4101 is located above the first air inlet channel 4051 and the second air inlet channel 4052, and a portion of the transmission gear 4101 is meshed with the matching rack 4053. When the transmission gear 4101 rotates counterclockwise, the air guide component 405 moves to the outside of the upper cavity, and at the same time, the moving block 6 moves to the second position in the middle area. When the transmission gear 4101 rotates clockwise, the air guide component 405 moves from the inside of the middle area to the inside of the upper cavity. After the air guide component 405 moves to the inside of the upper cavity, the moving block 6 resets from the second position to the first position.
