Referring to the drawings, an embodiment of the present invention provides a floor sweeping robot 100, which includes a housing 10 and a magnetic adsorbing member 20. Specifically, the housing 10 includes an upper housing assembly, a lower housing and a bottom cover, which are surrounded to form an installation cavity for installing components of the sweeping robot 100, such as a dust collection assembly, a floor mopping assembly, a main controller and a battery.

The bottom of the casing 10 is provided with a dust suction port 11, the dust suction port 11 is used for sucking external dust, the magnetic adsorption member 20 is installed at the bottom of the casing 10, the magnetic adsorption member 20 is located in front of the dust suction port 11 along the traveling direction, and the magnetic adsorption member 20 can generate magnetic adsorption force.

Specifically, the housing 10 has a rolling brush cavity 12, the sweeping robot 100 further includes a rolling brush 30, the rolling brush 30 is disposed in the rolling brush cavity 12, the dust suction port 11 is connected to the rolling brush 12, and the rolling brush 30 is at least convexly disposed on the dust suction port 11 to contact with the ground, so as to bring the dust on the ground into the rolling brush cavity 12, and further enter into a dust collecting box of the sweeping robot 100 under the action of suction. It should be understood that the source of the suction force of the suction opening 11 is the suction force generated by the fan of the cleaning robot 100. In some embodiments, the dust suction opening 11 and the magnetic attraction member 20 are disposed on the bottom cover.

So, when robot 100 is in the dust absorption mode and cleans ground sweeping the floor, the fan starts in order to produce suction, dust absorption mouth 11 can inhale outside dust, robot 100 walks along the direction of travel sweeping the floor, when meetting iron needle or other metal object, because the setting of magnetic adsorption piece 20, can adsorb metal object on magnetic adsorption piece 20, and because magnetic adsorption piece 20 is located the place ahead of dust absorption mouth 11, consequently, before metal object gets into dust absorption mouth 11, just can be adsorbed by magnetic adsorption piece 20, thereby can not follow dust absorption mouth 11 and inhale, and then can not cause dust absorption components such as unsteady gluey chamber or dust-collecting box filter screen to damage.

In some embodiments, the magnetic attraction member 20 comprises a permanent magnet. The permanent magnet can always generate magnetic adsorption force to adsorb metal objects below the casing 10 at any time. In other embodiments, the magnetic attraction member 20 may also include an electromagnet, and the sweeping robot 100 further includes a controller for controlling the electromagnet to be in a conducting state or a power-off state.

Thus, the suction loss is avoided while the position interference with other parts at the bottom of the casing 10 is avoided.

Preferably, the magnetic attraction member 20 includes two magnetic attraction members 20, and the two magnetic attraction members 20 are spaced apart from each other along the longitudinal direction of the dust suction port 11.

In some embodiments, the plurality of magnetic attraction members 20 are symmetrically arranged along the center line of the dust suction port 11. Thus, the magnetic attraction pieces 20 can be uniformly arranged in front of the dust suction opening 11, and the missing of attraction can be avoided.

Specifically, the magnetic attraction member 20 and the charging pole piece 40 are disposed at an interval in a first direction perpendicular to the traveling direction. More specifically, the magnetic attraction member 20 is located outside the charging pad 40 in the first direction. So, keep suitable interval between magnetic adsorption piece 20 and the pole piece 40 that charges to avoid the performance interference between the device, also avoid magnetic adsorption piece 20 to adsorb sheltering from the pole piece 40 that charges after the metal article, and influence the pole piece 40 that charges and fill the contact of electric pile and charge.

As shown in fig. 5, in some embodiments, the bottom wall of the casing 10 has a concave portion, the magnetic attraction member 20 is disposed in the concave portion, and a first receiving cavity 21 with an opening at the bottom is defined between the magnetic attraction member 20 and the inner wall of the concave portion. Therefore, after the magnetic adsorption piece 20 adsorbs the metal object, the metal object is accommodated in the first accommodating cavity 21, so as to prevent the metal object from protruding to the bottom of the housing 10, and the cleaning is blocked or the metal object collides with the ground and falls off in the subsequent moving process of the sweeping robot. Preferably, the magnetic attraction member 20 is located at the bottom of the recess. At this time, the first accommodating cavity 21 formed by the magnetic attraction piece 20 and the inner wall of the concave portion is the largest in volume, and accommodates more metal objects.
