Abstract

A thin-type automatic cleaning device includes a main body, a fan module and a dust collecting box. The main body includes a placing chamber for receiving the fan module. The structural shape of the dust collecting box substantially assorts with that of the placing chamber in order to be received within the placing chamber. The lower casing is provided with a receiving cavity from the bottom side toward the interior of the dust collecting box to receive the fan module. The dust collecting box forms a nested structure with the fan module thereby to reduce the thickness of the device.

Claims

1. A thin-type automatic cleaning device including:

a main body comprising a placing chamber;

a fan module provided within the placing chamber; and

a dust collecting box having a structural shape being substantially assorted with that of the placing chamber in order to be received within the placing chamber,

wherein the dust collecting box comprises an upper casing and a lower casing engaged with each other, and the lower casing is provided with a receiving cavity, which has a side wall, protruding from the bottom side toward the interior of the dust collecting box for receiving the fan module, and an air vacuuming opening facing toward the fan module is provided on the top of the receiving cavity.

2. The thin-type automatic cleaning device according to claim 1, wherein

a dust vacuuming opening extends to the placing chamber from a bottom surface of the main body, a dust collecting opening is provided in the lower casing of the dust collecting box in a position corresponding to the dust vacuuming opening in the main body, and an air vacuuming opening provided at the periphery of the placing chamber extends through the main body.

3. The thin-type automatic cleaning device according to claim 2, wherein

the dust collecting box further comprises a partition configured by a bracket and a filter net, and the partition is provided in the lower casing to be leaned against the air vacuuming opening.

4. The thin-type automatic cleaning device according to claim 1, wherein

the main body further comprises a top lid provided on the top side of the placing chamber and a bottom lid provided on the bottom side of the placing chamber, and the fan module is provided on the bottom lid.

5. The thin-type automatic cleaning device according to claim 4, further including

a control processing module, a moving module and a power switch, wherein the fan module, the moving module and the power switch are coupled to the control processing module, the power switch is selectively switches the device between an on state and an off state by external operation, an activated signal is transmitted to the control processing module to activate the moving module and the fan module when the power switch is switched to the on state.

6. The thin-type automatic cleaning device according to claim 5, further including a sealing sensing module coupled to the control processing module, wherein the sealing sensing module is used for detecting whether the top lid is sealed to the top of the placing chamber or not to transmit a first sensing signal to the control processing module, and the control processing module determines whether or not to activate the moving module and the fan module according to the first sensing signal.

7. The thin-type automatic cleaning device according to claim 6, wherein

a buckling section is provided on the top rim of the placing chamber, a fastener is provided on the top lid for engaging the buckling section so as to dispose the top lid on the top of the placing chamber, the sealing sensing module is disposed at the buckling section for detecting whether the fastener of the top lid is engaged to the buckling section.
