In the embodiment shown in fig. 2, the other end of the first dust inlet pipe 10 is connected to the second dust inlet pipe 13 through a flow guide baffle 11 and a magnetic attraction piece 12, and the flow guide baffle 11 and the magnetic attraction piece 12 cooperate with each other to control the connection and disconnection between the first dust inlet pipe 10 and the second dust inlet pipe 13 under the action of the dust collection fan 16. When the dust collected by the dust bag 14 is lighter than a preset weight threshold value, the dust bag 14 can generate a physical quantity to be conducted to the dust suction fan 16 and maintain normal operation thereof when a weight change factor can be sensed by using other associated physical structures or physical media in a dust box of the cleaning robot, a negative pressure is generated in the dust bag 14 and the second dust inlet pipe 13, the suction diversion baffle 11 is opened and is not attracted with the magnetic attraction piece 12, so that the dust suction fan 16 guides the diversion baffle 11 to communicate the second dust inlet pipe 13 with the first dust inlet pipe 10, thereby forming a negative pressure environment in the dust box, and the dust sucked by the cleaning robot from the outside enters the inside of the dust bag 14 along the first dust inlet pipe 10 and the second dust inlet pipe 13.

When the dust collected by the dust bag 14 is heavier than a preset weight threshold and/or the dust collection fan 16 does not work, that is, when the dust collected by the cleaning robot is too much, the dust bag 14 can trigger other associated physical structures or physical media in the dust collection box by using a weight factor, the contact sensing generates a physical quantity to trigger the dust collection fan 16 to stop working, so that the negative pressure environment of the dust collection fan 16 in the dust collection box and the first dust inlet pipeline 10 and the second dust inlet pipeline 13 arranged in the dust collection box disappears, the diversion baffle 11 and the magnetic attraction member 12 close and block the passage of the second dust inlet pipeline 13 and the first dust inlet pipeline 10 under the control of the magnetic attraction acting force, and the dust in the first dust inlet pipeline 10 and/or the second dust inlet pipeline 13 is prevented from flowing backwards and even flowing backwards outside the dust collection port of the cleaning robot due to the fact that the dust does not completely enter the dust bag 14, especially, residual dust in the dust channel is easy to leak out through the dust suction port to cause secondary pollution to the environment, and the leaked dust needs to be cleaned again in other modes, so that the steps of cleaning work are increased, and the simple cleaning control program is complicated.

In one embodiment, the dust bag 14 is disposed above the bottom of the dust box of the cleaning robot, and a sensor switch device 15 is disposed between the dust bag and the bottom of the dust box, the sensor switch device 15 is electrically connected to the dust suction fan 16, and the sensor switch device 15 is configured to maintain the dust suction fan to operate by an electrical signal if the sensor switch device 15 is subjected to a condition below a preset weight threshold or under the control of an external processor, so that a negative pressure environment is formed in the dust box, and the baffle 11 is blown to one side of the dust collection port (a passage between the second dust inlet pipe 13 and the dust bag 14) to enable sucked dust to be sucked into the dust bag 14 through the first dust inlet pipe 10. The sensing switch device 15 is used for pressing the sensing switch device 15 to a certain deformation degree when the sensing switch device 15 bears the condition that the weight exceeds a preset weight threshold value, the electric signal just changes to the corresponding threshold value, and then the electric signal is transmitted to the dust collection motor 16 as a trigger signal, so that the dust collection fan 16 is turned off through the electric signal, the negative pressure environment in the dust collection box of the cleaning robot disappears, the magnetic adsorption piece 12 attracts the diversion baffle plate 11, the second dust inlet pipeline 13 and the first dust inlet pipeline 10 are blocked, and the phenomenon that the dust flows back to the first dust inlet pipeline 10 when excessive dust is collected is avoided. Thus, the present embodiment allows the deflector and the magnetic attraction member to be naturally closed under the magnetic attraction force to block the passage of the second dust inlet pipe and the first dust inlet pipe when the first dust inlet pipe passes or has passed a large amount of dust. And maintaining the dust collection effect of the cleaning robot.

As an embodiment, a first trapezoidal fixing member 101 with a long top and a short bottom is disposed at the upper end inside the first dust inlet pipe 10, and at least one flow guide baffle plate 11 is mounted on the surface (inclined surface) of the first trapezoidal fixing member 101, so that the flow guide baffle plate 11 has a more sufficient space and is rotatably mounted on the first trapezoidal fixing member 101; the lower extreme of first dust inlet pipe 10 inside sets up short second trapezoidal mounting 102 of length from top to bottom, install on the slope face that the slope of second trapezoidal mounting 102 is upwards magnetic adsorption piece 12, so that at least one when dust absorption fan 16 is out of work, under the magnetic attraction with the slope face butt that the slope of second trapezoidal mounting 102 is upwards, close the through-hole that forms between second trapezoidal mounting 102 and the first trapezoidal mounting 101 for the dust that remains in dust inlet pipe can only fall into above-mentioned dust bag 14 along the trapezoidal slope, avoids these remaining dust to return first dust inlet pipe 10 along with the air current again, so that fall back on cleaning machines people's the dust absorption region. The slope of the second trapezoidal fixing part 102 is convenient for residual dust and garbage to quickly slide into the dust collecting bag 14, and the suction can be improved by arranging the reinforcing rib, so that the structural collision strength of the diversion baffle 11 in the process is improved, the structure is simple and practical, and the backflow pollution problem under a large number of dust collecting environments is effectively avoided.

Preferably, a heater is disposed at the periphery and bottom of the dust collecting box of the cleaning robot for drying the dust or garbage in the dust collecting bag 14 to prevent the dust or garbage in the dust collecting bag 14 from being adhered to the first dust inlet pipe 10 or the second dust inlet pipe 13.
