All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Embodiments of the present utility model are described below with reference to fig. 1 to 8.

As shown in fig. 1 and 8, according to an aspect of the present utility model, there is provided a cleaning robot 100, the cleaning robot 100 including: the dust collecting device comprises a base 110, a dust exhaust air channel 120, an inner baffle cover 130 and an outer baffle cover 140, wherein the base 110 is provided with a dust collecting cavity 111 and a shell 112, the dust collecting cavity 111 is provided with an inner dust exhaust opening 1111, the shell 112 is provided with an outer dust exhaust opening 1121, one end of the dust exhaust air channel 120 is in butt joint with the inner dust exhaust opening 1111, the other end of the dust exhaust air channel 120 is in butt joint with the outer dust exhaust opening 1121, the inner baffle cover 130 is rotationally connected with the inner dust exhaust opening 1111, the outer baffle cover 140 is rotationally connected with the outer dust exhaust opening 1121, and the outer baffle cover 140 and the inner baffle cover 130 can be synchronously and co-directionally opened under the action of suction force so as to exhaust garbage in the dust collecting cavity 111 out of the outer dust exhaust opening 1121.

The base 110 is provided with a dust collecting cavity 111, the dust collecting cavity 111 is provided with a dust inlet and an inner dust outlet 1111, a filter screen assembly is arranged in the dust collecting cavity 111, the filter screen assembly can filter the dust and the garbage entering from the dust inlet, the dust and the garbage remained in the dust collecting cavity 111 can enter the dust exhaust air channel 120 through the inner dust outlet 1111, and then the dust and the garbage are discharged from the outer dust outlet 1121 to the base 110.

The inner barrier cover 130 is rotatably connected to the inner dust exhaust outlet 1111, so that the inner barrier cover 130 can block the inner dust exhaust outlet 1111 and can also open the inner dust exhaust outlet 1111. When the inner baffle cover 130 shields the inner dust exhaust 1111, the dust collecting chamber 111 is facilitated to collect the dust. When the inner barrier cover 130 opens the inner dust exhaust port 1111, the dust and the dust in the dust collection chamber 111 can be sucked into the dust exhaust duct 120. Similarly, when the outer shield 140 shields the outer dust outlet 1121, the dust collecting chamber 111 is also beneficial to collect garbage and dust. When the outer cover 140 opens the outer dust discharge port 1121, the dust and dirt entering the dust discharge duct 120 can be discharged from the outer dust discharge port 1121.

The outer blocking cover 140 and the inner blocking cover 130 are respectively rotatable, and overcome the force to be overcome when the outer blocking cover 140 and the inner blocking cover 130 rotate through the suction force, so that the outer blocking cover 140 and the inner blocking cover 130 rotate under the action of the suction force, and the outer blocking cover 140 and the inner blocking cover 130 can synchronously rotate and rotate towards one direction under the action of the suction force. It will be understood that when the dust and the dust in the dust box are sucked into the dust exhaust duct 120 by the suction force, the source of the suction force is at least disposed at the outer dust exhaust port 1121, and therefore, the inner cover 130 needs to be turned toward the outer dust exhaust port 1121, so that the inner cover 130 can be inserted into the dust exhaust duct 120 after being turned. The outer cover 140 also turns in the same direction, so that the outer cover 140 avoids the outer dust discharge port 1121, and thus, the garbage can be discharged from the outer dust discharge port 1121, and the garbage can be prevented from being accumulated and jammed in the dust discharge duct 120.

It should be further noted that, since the outer cover 140 and the inner cover 130 are rotatable, when the suction force is larger, the opening angle of the outer cover 140 and the inner cover 130 is larger, so that the opening angle of the inner cover 130 and the outer cover 140 can be controlled by controlling the suction force, so that the opening angle of the inner cover 130 and the outer cover 140 is as large as possible, and the garbage and dust in the dust collecting cavity 111 can be discharged from the outer dust outlet 1121 more smoothly.

In addition, the outer barrier cover 140 and the inner barrier cover 130 need to be opened or closed simultaneously, if the inner barrier cover 130 is opened first and the outer barrier cover 140 is opened later, or the outer barrier cover 140 is opened at a small angle and the inner barrier cover 130 is opened in place, the garbage is blocked by the outer barrier cover 140 when entering the dust exhaust duct 120, so that the garbage is blocked in the dust exhaust duct 120; when the dust collection is completed, the outer barrier cover 140 is closed earlier than the inner barrier cover 130, and thus, the dust is deposited in the dust exhaust duct 120, resulting in a backflow of the dust.

When the torsion spring 143 stores energy, that is, the suction force overcomes the energy stored in the torsion spring 143 to rotate the rotation shaft, the outer baffle 141 can open the outer dust discharge port 1121. When the torsion spring 143 releases energy, i.e., the suction force is reduced or lost, the outer baffle 141 is caused to fall back during this process to block the outer dust discharge port 1121.

The mounting portion is provided at an end of the arc portion near one end of the outer barrier 141, and is used for mounting the rotation shaft 142. Wherein, the installation department is equipped with the round hole for install the axis of rotation.

Since the rotation shaft 142 is installed at the inner side of the housing 112, when the outer barrier 141 is turned outward to be opened, the housing 112 can be avoided by providing the bending member 144, so that the outer barrier 141 can be smoothly turned outward. It will also be appreciated that the grooves of the flexure 144 may form relief spaces.

When the rotation shaft 142 includes the first shaft 1421 and the second shaft 1422, the installation parts are provided in two, and the installation structure of the rotation shaft 142 is made more firm by passing the rotation shaft 142 through the installation parts.
