Description

 Draw device, dust box and cleaning robot thereof  

The present invention relates to a robot, and more particularly to a dust box of a cleaning robot comprising a suction device.

Smart home has infiltrated into all aspects of life without knowing it. Especially in smart home appliances, cleaning robots can be regarded as one of the relatively mature home appliances. With the control of artificial intelligence, the cleaning robot can be controlled without humans. Automatically sweeps and dusts back and forth on the ground.

Cleaning performance is one of the key points of cleaning robot considerations, and the cleaning effect will vary with the design of the cleaning brush and vacuum module, and the two need to cooperate with each other, otherwise the cleaning effect will be greatly reduced, such as the US invention patent. No. 7200892 proposes a structure in which the brush can be adjusted according to the ground to be cleaned, and a dust suction port is arranged behind the brush, and a guide airflow is arranged at the distance between the brush and the dust suction port to make the dirt cleaned by the sweeping brush. The object is guided to the suction port for suction collection. Another example is Taiwan Invention Patent No. I481377, which proposes a self-propelled cleaning device with two negative pressure suction ports, one on the opposite side of the travel path and the other on the opposite side of the travel path, using multiple suction openings to enhance cleaning. effectiveness.

However, in the above-mentioned cleaning method, the sweeping brush is used to dial the dirt to the suction port. Since the carpet is a non-planar cleaned surface, this method cannot achieve a cleaning effect because the sweeping brush on the market is usually flexible. The soft material taken in this kind of environment can't smoothly lift the dirt. Therefore, even if the cleaning robot has multiple suction ports, it is impossible to inhale the dirt at the root of the carpet by negative pressure alone. It is necessary to have the necessary issues to improve.

In view of the above problems, according to the present invention, a pick-up device, a dust collecting box thereof and a cleaning robot thereof are used to improve the cleaning effect of the cleaning robot by the auxiliary action of the dialing device.

In order to achieve the above objects and effects, the present invention provides a dial suction device comprising a combination body and a plurality of protruding tube bodies. The combined system provides a combined dialing device at the air inlet of the dust box, and the protruding body is provided with the protruding tube at a position opposite to the air inlet, and the protruding tubes extend toward the surface to be cleaned, and the protruding tube The two ends of the body respectively have a first opening communicating with the airflow inlet of the dust box and a second opening opened by the cleaning robot to guide the airflow to absorb the dirt of the external environment into the protruding pipe body.

In order to achieve the above objects and effects, the present invention provides a dust collecting case comprising a housing and the above-mentioned dialing device. The foregoing housing can be housed in a cleaning robot, and the housing comprises: an accommodation space, an air flow outlet, and an air flow inlet. The inside of the housing is an accommodating space for accommodating the sucked dirt; the housing is provided with an air outlet connected to the accommodating space at a position where the cleaning robot guides the dust box gas out; the housing faces An airflow inlet is provided on one side of the surface to be cleaned.

In order to achieve the above objects and effects, the present invention provides a cleaning robot comprising the dust box described above.

Wherein, when the cleaning robot is running, the protruding pipes move the cleaned surface, so that the dirt on the cleaned surface (such as the carpet and the root of the felt) is swiped and then leaves the cleaned surface, and the cleaning robot will When the gas of the external environment is guided into the accommodating space from the second opening of the protruding pipe body, the dirt enters the accommodating space with the airflow, and the filter is provided at the outlet of the airflow, and the dirty matter stays in the accommodating space. And the gas entering the accommodating space will be guided away from the casing by the cleaning robot from the air outlet.

In summary, the present invention has one or more of the following advantages:

1. The suction device can be used to move the surface to be cleaned (such as a carpet or a blanket), which makes it easy to remove dirt from the surface to be cleaned.

2. The suction device has a protruding pipe body extending toward the surface to be cleaned, which can protrude into the surface to be cleaned and deeply clean the root of the surface to be cleaned.
