Further, as shown in fig. 1, according to an embodiment of the present application, the cleaning robot main body 20 has a dust collecting bin 21, the dust collecting bin 21 is located below the fan assembly 10, a dust suction port 211 is formed on a side surface of the dust collecting bin 21, the fan assembly 10 further includes an air inlet duct 13 integrally connected to the fan bottom cover 122, the air inlet duct 13 extends from the bottom surface of the fan bottom cover 122 to the upper side of the dust suction port 211 of the dust collecting bin 21, and the air inlet duct 13 communicates with the motor air inlet 111 below the fan motor 11. So set up, extend this fan motor 11 to the side with this fan bottom 122 towards the air intake of the bottom surface of this fan bottom 122 originally for this air inlet duct 13 is located the top position of this dust absorption mouth 211 of this dust collection bin 21 of this robot 1 of should sweeping the floor towards the side of this robot 1 of should sweeping the floor, avoids inhaling subaerial debris such as dust or rubbish and leading to the fact the influence to this fan motor 11 when this robot 1 of sweeping the floor during operation. Inhaled debris not only can collide with the flabellum and further produce bigger noise, influence user experience, can be to the harm that causes of fan motor 11 moreover, influence fan motor 11's life-span.

It will be appreciated that according to one embodiment of the present application, the diameter width of the inlet duct 13 at the duct inlet 133 is the largest, so that the inlet air volume can be increased, and the suction force of the fan assembly 10 can be increased.

It should be noted that, as shown in fig. 1, according to an embodiment of the present application, the flexible assembly 15 further includes a third flexible member 153, and the third flexible member 153 is sleeved on the duct air inlet 133 of the air inlet duct 13 and is located between the air inlet duct 13 and the sweeping robot main body 20. So set up, when should sweep the floor the robot 1 during operation, can cushion the vibration between the relative robot main part 20 that should sweep the floor of this air inlet duct 13, reduce the noise.

Preferably, as shown in fig. 1 and fig. 2, according to an embodiment of the present application, an edge of the air inlet duct 13 protrudes outward to form a limiting rib 134, a buckle 135 is disposed outside the duct air inlet 133 of the air inlet duct 13, and the third flexible member 153 abuts against the limiting rib 134 and is clamped to the buckle 135. So set up, this third flexible 153 is located this air inlet duct 13's outside through this buckle 135 card, avoids this third flexible 153 to take place to slide owing to this air inlet duct 13 vibration, influences its ability of buffering this air inlet duct 13 vibration.

More preferably, as shown in fig. 4, according to an embodiment of the present application, support ribs connected to the upper surface and the lower surface of the intake air duct 13 are fixedly disposed in the duct air inlet 133 of the intake air duct 13. The support ribs vertically support the upper surface and the lower surface of the air inlet duct 13, preventing the air inlet of the air inlet duct 13 from being deformed.

It should be noted that, as shown in fig. 2 and 3, according to an embodiment of the present application, the air inlet duct 13 includes an air inlet upper cover 131 and an air inlet lower cover 132, the air inlet upper cover 131 is integrally connected to the fan bottom cover 122, and the air inlet lower cover 132 is detachably mounted to the air inlet upper cover 131. So set up, this air inlet duct 13 and this fan bottom cover 122's cooperation is inseparabler, and the noise that the vibration produced is littleer.

In particular, as shown in fig. 3 and 5, since the noise generated by the fan at the air outlet 112 is influenced by the length of the air duct, the too short air duct is not favorable for reducing the noise of the air outlet 112. An extended outlet duct 14 is required to reduce the noise generated at the outlet 112 of the fan motor 11. However, the connection between the air outlet duct 14 and the fan motor 11 is difficult to be completely flat, and a certain deviation may occur. If the air outlet duct 14 is not flat in the joint with the fan motor 11, when the fan motor 11 works, the air outlet duct 14 and the fan motor 11 vibrate relatively to generate noise. According to an embodiment of the present application, the fan assembly 10 further includes an air outlet duct 14, the air outlet duct 14 is fixedly disposed on the fan housing 12 and is communicated with the air outlet 112 of the fan motor 11, and the flexible assembly 15 further includes a fourth flexible member 154, and the fourth flexible member 154 is disposed between the air outlet 112 of the fan motor 11 and the air outlet duct 14. So set up, this fourth flexible piece 154 has filled the clearance between this air outlet 112 of this fan motor 11 and this air-out wind channel 14, makes its connection level and smooth to the relative vibration of this fan motor 11 and this air-out wind channel 14 is cushioned, reduces the noise of the air outlet 112 of this fan motor 11.

Alternatively, as shown in fig. 5 and 6, according to an embodiment of the present application, in order to better eliminate the noise generated at the air outlet 112, the air outlet duct 14 includes a shielding member 143 fixed inside the air outlet duct 14. When the blower motor 11 drives the air to flow through the shielding member 143 fixed in the air outlet duct 14, the air is blocked by the shielding member 143 to work to consume kinetic energy of the air flowing through, so as to reduce noise generated by the air flowing out of the air outlet 112.

Preferably, as shown in fig. 5 and fig. 6, according to an embodiment of the present application, the air outlet duct 14 includes an air outlet lower cover 142 and an air outlet upper cover 141 fixedly disposed on the air outlet lower cover 142, and the plurality of shielding members 143 are respectively protruded from the air outlet upper cover 141 and the air outlet lower cover 142 at intervals. With such an arrangement, the air outlet duct 14 is divided into the upper air outlet cover 141 and the lower air outlet cover 142, which is more convenient for installing the air outlet duct 14 to the air outlet 112 of the fan motor 11. The shielding piece 143 is protruded on the upper outlet cover 141 and the lower outlet cover 142, so that the installation and fixation of the shielding piece 143 are simplified. The plurality of shielding members 143 are spaced apart from each other, so as to absorb the kinetic energy of the air flowing through the plurality of shielding members in a sectional manner, thereby further enhancing the noise generated by the fan motor 11 at the outlet 112.

Alternatively, the flexible member 15 is made of a soft gel material according to one embodiment of the present application. The soft rubber material has good elasticity, temperature resistance and biological aging resistance, and the service life is longer under natural conditions.

According to an embodiment of the present application, a sound absorbing material is laid in the air outlet duct 14. So set up, further strengthened this air outlet duct 14's noise silencing ability.

Specifically, as shown in fig. 2, according to an embodiment of the present application, the upper fan cover 121 is fastened to the lower fan cover 122, the lower intake cover 132 is fastened to the upper intake cover 131, and the upper outlet cover 141 is fastened to the lower outlet cover 142.

It should be noted that, according to an embodiment of the present application, the cleaning robot 1 further includes a main board 30, and the main board 30 is fixedly disposed above the fan assembly 10. So set up, this fan subassembly 10 separates this mainboard 30 and this dust collecting bin 21 of this robot 1 of sweeping the floor, avoids this robot 1 of sweeping the floor to inhale the steam accumulation in this dust collecting bin 21 and causes this mainboard 30 short circuit.
