[0041] like Figure 4-14 As shown, the utility model discloses a second embodiment of a base station dust removal system, which includes a handheld cleaning device and a base station 2000 connected to the handheld cleaning device.

[0042] The handheld cleaning device includes a handheld host 1000, a connecting tube 1300 connected to the handheld host 1000 at one end and connected to the air inlet body 1220, and a floor brush 1500 connected to the other end of the connecting tube 1300; wherein the handheld host 1000 includes a body 1200, a dust cup 1400 connected to the body 1200 and having a dust cup air inlet 1422, a host motor 1600 located in the body 1200 and downstream of the dust cup 1400, and a valve assembly 1700 for closing or opening the dust cup air inlet 1422. The movement direction of the valve assembly 1700 is parallel to the central axis direction of the dust cup 1400, and the valve assembly 1700 is located downstream of the connecting tube 1300. The connecting tube 1300 has a connecting tube cavity 1320 located downstream of the dust cup air inlet 1422 and upstream of the floor brush 1500.

[0043] The air inlet body 1220 includes a body air inlet 1222 located at one end and connected to the connecting tube cavity 1320, a body air outlet 1224 located at the other end and connected to the dust cup air inlet 1422, a body buckle 1226 located between the body air inlet 1222 and the body air outlet 1224, and a valve port 1228 connected to the body air outlet 1224.

[0044] The valve assembly 1700 includes a valve base 1710, a pair of valve docking parts 1712 disposed on both sides of the valve base 1710, a valve buckle 1714 located at one end of the valve base 1710 and between the two valve docking parts 1712, and a valve plate 1716 located at the other end of the valve base 1710 and closing or opening the dust cup air inlet 1422. One end of the valve assembly spring 1720 is fixed to the body buckle 1226, and the other end is fixed to the valve buckle 1714. The valve plate 1716 can enter the body air outlet 1224 through the valve port 1228.

[0045] This embodiment further includes a push rod member connected to the valve assembly 1700, which includes a push rod base 2322, a rod-shaped portion 2324 located at one end of the push rod base 2322 and docked with the valve docking portion 1712, and a matching portion 2326 located at the other end of the push rod base 2322.

[0046] The base station 2000 includes a base station housing portion 2200 that at least partially houses the dust cup 1400, a base station connecting portion 2400 connected to the base station housing portion 2200 at one end, and a base station dust collecting portion connected to the other end of the base station connecting portion 2400 and having a base station motor 2600. The base station housing part 2200 includes a housing part shell 2220 with a hollow interior, and a housing part cover body 2240 at least partially surrounded by the housing part shell 2220, wherein the housing part shell 2220 includes a housing cavity 2222, and a housing groove 2224 located outside the housing cavity 2222 and at least partially accommodating the connecting pipe 1300; wherein the housing part cover body 2240 includes a cover body joint 2242 which can pass through the shell cavity 2222 and is hollow inside and connected to the base station connecting part 2400, a cover body cavity 2244 which is internally connected to the cover body joint 2242, a cover body groove 2246 allowing the connecting pipe 1300 to pass through, an inclined protrusion 2248 located on one side of the cover body cavity 2244 and cooperating with the inclined surface 1484, and a pair of push rods 2249 arranged in the cover body groove 2246 and cooperating with the matching part 2326 of the push rod member. The base station connection part 2400 is tubular, and its cross-sectional area is greater than or equal to the cross-sectional area of ​​the connection tube 1300. The base station dust collecting part has a base station dust collecting cavity 2020 to accommodate a dust bag.

[0047] Before the base station dust removal system of this embodiment works, the dust cup 1400 needs to be placed in the cover body cavity 2244 in advance, and at the same time, the push rod 2249 forces the matching part 2326 of the push rod to move upward, stretching the valve assembly spring 1720, and the valve docking part 1712 drives the valve plate 1716 to completely cover the dust cup air inlet 1422 or partially cover the dust cup air inlet 1422, and the inclined protrusion 2248 cooperates with the inclined surface 1484 to press the unlocking spring 1490 to move upward, so that the lock hook 1482 and the dust cup cover lock buckle 1462 are unlocked, and then the dust cup cover 146 0 rotates around the dust cup cover rotating shaft 1464 to open the end hole 1472, so that the dust in the dust cup cavity 1420 enters the cover body cavity 2244, and then after the base station motor 2600 is started, the dust in the dust cup cavity 1420, under the action of negative pressure, especially the dust attached to the inside of the cyclone net cover part 1440 or the dust attached to the filter, flows out from the inside of the cyclone net cover part 1440 to the outside under the drive of the airflow, so that the dust in the dust cup cavity 1420 goes down along the inside of the base station connecting part 2400 and enters the base station dust collection cavity 2020 of the base station dust collection part. That is, when the base station collects dust, the valve assembly is closed, the dust cup air inlet 1422 does not enter the airflow, and the airflow flows in reverse through the cyclone net cover and the filter, so that the garbage in the cyclone net cover, the filter and the dust cup can be cleaned and the use time of the filter can be extended. Similarly, the valve assembly may not be completely closed, and the dust cup can also be cleaned by breaking the cyclone system.

[0048] The utility model has the advantages that when the base station is started, the airflow in the dust cup of the handheld cleaning device is ensured to move in an orderly manner, the interference of the cyclone is reduced, the dust in the dust cup is conveniently sucked out, and at the same time the dust attached to the cyclone mesh cover and the filter element can be cleaned in the opposite direction, thereby reducing blockage and extending the service life of the filter element.

[0049] The above are only preferred implementations of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field can make several modifications and improvements without departing from the creative concept of the present utility model, which should be included in the protection scope of the present utility model.
