A dust suction and charging device for a floor sweeping robot, comprising a maintenance station and a floor sweeping robot;
- a charging and dust suction base is provided in a lower portion of the maintenance station, and a maintenance-station dust suction port is formed on the charging and dust suction base;
- a dust bag accommodating box is arranged inside the maintenance station, and a dust bag is arranged inside the dust bag accommodating box;
- a dust suction fan is arranged outside the dust bag accommodating box and located in a cavity of the maintenance station, and an air suction port of the dust suction fan is communicated with the dust bag accommodating box to allow a negative pressure to be generated in the dust bag accommodating box;
- one end of a dust suction hose comes into contact with a dust inlet end of the dust bag, while the other end of the dust suction hose is fixedly connected to the maintenance-station dust suction port;
- the floor sweeping robot has a floor sweeping robot body;
- a dust box is arranged on one side of the floor sweeping robot;
- a dust-box discharge port is formed on a bottom of the dust box;
- the dust-box discharge port corresponds to the maintenance-station dust suction port;
- and, the maintenance-station dust suction port is communicated with the dust-box discharge port by pressing an outer surface of the maintenance-station dust suction port;
- and
- the dust-box discharge port has a dust inlet end and a dust discharge end;
- a check valve assembly is mounted on an outer side of the dust inlet end;
- the check valve assembly comprises a valve, a valve torsion spring and a valve rotating shaft;
- the valve rotating shaft is fixedly mounted on the outer side of the dust inlet end;
- the valve is rotatably mounted on the valve rotating shaft;
- when the valve is rotated and pressed onto the dust inlet end, the valve seals the dust inlet end;
- the valve torsion spring is arranged on an outer side face of the valve and is used for applying, to the valve, a press force toward the dust inlet end, so as to press the valve onto the dust inlet end;
- and, when the outer side face of the valve is under a negative pressure, due to the negative pressure, the valve overcomes the press force from the valve torsion spring and moves in an opposite direction to open the dust inlet end;
- wherein a water tank is detachably mounted on a bottom of the floor sweeping robot body and located outside the dust-box discharge port, and a water tank detector for detecting whether the water tank is mounted is arranged on the floor sweeping robot body;
- wherein a maintenance station contact tab is arranged on the charging and dust suction base, a charging contact tab is mounted at one end of the bottom of the floor sweeping robot body, and a dust discharge contact tab is mounted on the other end of the bottom of the floor sweeping robot body;
- a floor sweeping robot mainboard and a rechargeable battery are mounted inside the floor sweeping robot body;
- a first pin of the floor sweeping robot mainboard is electrically connected to the dust discharge contact tab;
- a second pin of the floor sweeping robot mainboard is connected to one end of the rechargeable battery, and the other end of the rechargeable battery is electrically connected to the charging contact tab;
- and the floor sweeping robot mainboard is also electrically connected to the water tank detector;
- and
- a maintenance station controller is mounted in the maintenance station, and the maintenance station controller is connected to the maintenance station contact tab, the dust suction fan and a charging control circuit, respectively.
