As shown in fig. 1 and 10, a base station 1000 is provided in an embodiment that can be used to provide a dust collection function for a surface cleaning apparatus 2000 such as a sweeper or scrubber.

As shown in fig. 1 and 3, the base station 1000 may include a housing 100, a dust collection mechanism 200, and an electrostatic precipitation mechanism 300.

Wherein the dust collection mechanism 200 may be installed in the housing 100. In an embodiment, the dust collection mechanism 200 may include a fan 210 for providing power. In use, the dust collection mechanism 200 may be in communication with a dust box of the surface cleaning apparatus 2000. The blower 210 may create a negative pressure environment inside the dust collection mechanism 200 to provide suction so that dirt in the dust box of the surface cleaning apparatus 2000 may be sucked into the dust collection mechanism 200 and remain in the dust collection mechanism 200.

It is understood that the blower 210 may be provided with a first air outlet 2111 communicating the inside of the blower 210 with the inside of the housing 100. In an embodiment, the electrostatic precipitation mechanism 300 may be installed at the first air outlet 2111. Therefore, when the air flow is discharged from the blower 210 to the inside of the housing 100 through the first air outlet 2111, the electrostatic precipitator 300 can provide further filtration to the air flow, and can filter out dirt such as fine dust in the air flow, so as to prevent the dust from entering the inside of the housing 100 to erode other components in the housing 100, and avoid the failure of other components in the housing 100 due to oxidization. Furthermore, the failure rate of the base station 1000 can be reduced, the maintenance cost in the later period can be reduced, and the service life of the base station 1000 can be prolonged.

As shown in fig. 3 and 5, further, the fan 210 may include a fan housing 211 and a movement (not shown). The inside of the fan housing 211 is a hollow structure, and the movement can be installed in the fan housing 211. The first air outlet 2111 may be opened on the fan housing 211, and may communicate the inside of the fan housing 211 with the inside of the housing 100. Accordingly, the electrostatic precipitator mechanism 300 may be mounted on the blower housing 211 and covers the first air outlet 2111.

Referring again to fig. 8, it will be appreciated that dust collection mechanism 200 further includes a dust bag 220 for collecting dirt, one end of dust bag 220 being in communication with blower 210, and the other end of dust bag 220 being in communication with a dust box of surface cleaning apparatus 2000.

In use, the blower 210 can draw negative pressure into the dust bag 220, so that dirt in the dust box of the surface cleaning apparatus 2000 can be sucked into the dust bag 220 and retained in the dust bag 220 under the action of the negative pressure, and air flow can enter the blower 210 after being filtered by the dust bag 220. Typically, the dust bag 220 may be made of non-woven fabric, so that no part of dirt such as fine dust is introduced into the blower 210 through the dust bag 220. In the embodiment, the electrostatic dust collection mechanism 300 is disposed at the first air outlet 2111 of the fan housing 211, so that the air flowing through the electrostatic dust collection mechanism can be filtered again, fine dirt in the air can be filtered, and the dirt can be prevented from entering the housing 100 to erode other components in the housing 100.

In some embodiments, a side of the fan housing 211 remote from the movement may be convexly provided with a fitting tube 2112, the fitting tube 2112 may be disposed around the circumference of the first air outlet 2111, and a cross-sectional shape of the fitting tube 2112 may be adapted to a shape of the electrostatic precipitator mechanism 300, and the electrostatic precipitator mechanism 300 may be installed in the fitting tube 2112.

Referring again to fig. 4, 6 and 7, the electrostatic precipitator mechanism 300 may comprise an insulating support 310, a positive electrode sheet 320 and a first negative electrode sheet 330. The insulating support 310 may be used as a mounting carrier in the electrostatic precipitator mechanism 300, and the positive electrode tab 320 and the first negative electrode tab 330 may be mounted in a manner of being attached to the insulating support 310.

On the one hand, when the positive electrode tab 320 and the first negative electrode tab 330 are energized, dirt such as dust can be adsorbed on the first negative electrode tab 330, so that the content of dirt such as dust flowing through the air flow is reduced.

On the other hand, when the positive electrode tab 320 and the first negative electrode tab 330 are energized, a negative ion generator can be formed between the positive electrode tab 320 and the first negative electrode tab 330, and high-concentration negative ions can be continuously generated. Bacteria in the air flow can be extremely surrounded by negative ions, and negatively charged bacteria can rapidly undergo electrolytic reaction under the infiltration of high-concentration and high-energy negative ions, so that the cell walls of the bacteria are severely damaged, and the bacteria die. Furthermore, the peculiar smell in the air flow can be reduced, the influence of the peculiar smell and bacteria on the health of the user caused by the fact that the peculiar smell and the bacteria return to the indoor environment again is avoided, and secondary pollution is prevented.

In addition, when the positive electrode plate 320 and the first negative electrode plate 330 are electrified, a high-voltage electrostatic field can be generated between the positive electrode plate 320 and the first negative electrode plate 330, so that oxygen in the air flow can be ionized, and ozone with a certain concentration can be generated. Therefore, bacteria and peculiar smell in the air flow can be removed by ozone, so that the bacteria and peculiar smell are further prevented from being discharged to the indoor environment, namely secondary pollution is further blocked, and the cleanliness of the indoor environment is improved.

In an embodiment, a second ventilation slot 3112 may be disposed between two adjacent first ventilation slots 3111. The plurality of second negative electrode sheets 340 may be installed at the plurality of second ventilating slots 3112 in one-to-one correspondence and spaced apart from the positive electrode sheet 320 to be insulated. In the embodiment, by setting the second negative electrode pieces 340, the number of negative electrode pieces in the electrostatic dust collection mechanism 300 can be increased, so that the dust adsorption effect can be improved, and the cleanliness of the airflow can be improved.

In an embodiment, a plurality of positive electrode sheets 320 may be connected in series. The plurality of first negative electrode tabs 330 and the plurality of second negative electrode tabs 340 may be sequentially connected in series.
