Abstract

A dust collection sensing device of an automatic cleaner comprises: a main body with a placing chamber provided inside and a channel is provided on a side of the placing chamber, a dust collecting box installed within the placing chamber and an extended vacuuming pipe being provided on a side of the dust collecting box with an end thereof extending though the channel, a sensing assembly comprising a signal sending element and a signal receiving element, which are installed separately on the two opposite wall surfaces of the channel and are corresponding to the two sides of the bottom of the vacuuming pipe, and a warning indicator installed on the main body and connected to the signal receiving element of the sensing assembly electrically.

Claims

1. A dust collection sensing device of an automatic cleaner, comprising:

a main body for being as a dust-vacuuming cleaner with a controlling logic of an autonomous mobile robot, in which a placing chamber is provided, and a channel connected to the outside of the main body being provided on a side of the placing chamber, and the placing chamber being communicated with an air-extracting chamber inside the main body, and an air-extracting device being installed within the air-extracting chamber;

a dust collecting box, placing within the placing chamber, for being as a housing body forming a containing space, in which an extracting port corresponds to an opening of the air-extracting chamber being provided on the dust collecting box, and an extended vacuuming pipe being provided on a side of the dust collecting box to communicate with an inner space of the dust collecting box in correspondence to the channel of the main body with one end of the vacuuming pipe extending through the channel;

a sensing assembly, comprising a signal sending element and a signal receiving element correspondingly, the signal sending element and the signal receiving element being installed separately on the two opposite wall surfaces of the channel and being provided on two sides of the bottom of the vacuuming pipe, in which the signal sending element and the signal receiving element of the sensing assembly may be electronic components that are able to transmit sensing signals by a specific light source, and;

a warning indicator installed on the main body and electrically connected to the signal receiving element of the sensing assembly, in which the warning indicator transmits a warning by setting an electric logic when the sensing signal between the signal sending element and the signal receiving element is interrupted.

2. The dust collection sensing device of an automatic cleaner as claimed in claim 1, wherein the warning indicator utilizes a light source to transmit the warning, and the warning indicator is installed on an outside surface of an external shell of the main body.

3. The dust collection sensing device of an automatic cleaner as claimed in claim 2, wherein the warning indicator is a flash LED lamp.

4. The dust collection sensing device of an automatic cleaner as claimed in claim 1, wherein the warning indicator utilizes a sound speaker to transmit the warning, and the warning indicator is installed within the main body or on the outside surface of the main body.

5. The dust collection sensing device of an automatic cleaner as claimed in claim 4, wherein the warning indicator is a buzzer.
