Fig. 1 shows an enlarged view of the air duct of the sweeping robot in an angle according to the embodiment of the present invention. Fig. 2 is a top view of the sweeping robot shown in fig. 1 at a wind channel. As shown in fig. 1 and fig. 2, the present embodiment relates to a sweeping robot 100, which includes a main body 1, a fan 3, an air guide partition plate 4, and a sound absorption pad 5. Wherein, an air inlet and an air outlet 11 are formed on the main body 1. The air duct 2 is formed on the main body 1 and connected to the air inlet and outlet 11. The fan 3 is disposed in the air duct 2. The air guide partition plate 4 is arranged in the air duct 2 and is positioned between the fan 3 and the air outlet 11 of the main body 1. The air guide partition plate 4 partially shields the air outlet 11. The sound absorption pads 5 cover both sides of the air guide partition plate 4. The sound absorbing pad 5 is preferably, but not limited to, a noise reduction sponge, a foamed glass, a foamed metal, or the like, and for example, in the present embodiment, the sound absorbing pad 5 is selected to be made of a noise reduction sponge. In the using process, the fan 3 can generate negative pressure in the air duct 2, so that external air flow carrying dust and impurities on the ground enters the air duct 2 and is discharged from the air outlet 11. Preferably, a dust storage chamber is also formed in the air duct 2. The dust storage cavity is positioned between the air inlet and the fan 3 and can store dust and sundries carried in air flow, so that the filtered clean air flow is discharged from the air outlet 11 of the main body 1 to achieve the effect of cleaning the indoor environment.

As can be seen from the above technical solutions, the cleaning robot 100 of the present embodiment mainly adds the air guide partition plate 4 and the sound absorption pad 5 covering the air guide partition plate 4 in the air duct 2. The air guide partition plate 4 can change the flow direction of the air flow in the air duct 2. The air flow in the air duct 2 can bypass the air guide partition plate 4 and then be blown out outwards, so that the flow path of the air flow in the air duct 2 is greatly prolonged under the condition that the size of the air duct 2 is not increased, the air flow in the air duct 2 is more stable, and the noise generated by the friction between the air flow and the inner wall of the air duct 2 can be reduced. Meanwhile, the sound absorption pads 5 on the two sides of the air guide partition plate 4 can absorb noise in the air duct 2, so that a better noise reduction effect is achieved. Therefore, the sweeping robot 100 of the embodiment can overcome the defect of large noise in the air duct 2 of the sweeping robot 100 in the prior art, and can weaken the noise generated in the operation process of the sweeping robot 100, thereby being beneficial to improving the user experience. In addition, because the air duct 2 of the sweeping robot 100 of the present invention has a long length, the air flow discharged from the air outlet 11 is relatively smooth, and it is not easy to blow up the dust on the ground to pollute the indoor air, which affects the health of the user, and it can ensure that the dust on the ground is smoothly recovered by the sweeping robot 100.

In this embodiment, the air guiding partition plate 4 is obliquely arranged in the air duct 2, and an included angle between the air guiding partition plate and the direction of the air flow in the air duct 2 is an obtuse angle. This makes wind-guiding baffle 4 can enough the air current outwards discharge, can further prolong the length in wind channel 2 again, and simultaneously, the length of the wind-guiding baffle 4 that the slope set up is longer, and the area of the sound absorbing pad 5 on the wind-guiding baffle 4 is great, can further reduce the noise that robot 100 of sweeping the floor produced in the operation. The air guide partition plate 4 can be a straight plate or an arc-shaped air guide partition plate. For example, in the present embodiment, the air guide partition plate 4 is provided in an arc shape, and it is possible to reduce the wind resistance generated when the air flow flows along the air guide partition plate 4, and to more smoothly blow out the air flow. Preferably, the air guiding partition 4 protrudes toward one side of the fan 3, and can guide the airflow to generate a tendency of flowing outwards.

In the present embodiment, the number of the air guide partitions 4 is plural. Any two adjacent air guide partition plates 4 are connected with different side walls of the air duct 2. Can form snakelike wind channel between a plurality of wind-guiding baffles 4, snakelike wind channel can enough prolong the length in wind channel 2 greatly, can make the air current in the wind channel 2 turn to repeatedly again, weakens the wind speed of the air outlet 11 department of robot 100 of sweeping the floor, further reduces the air current of air outlet 11 department and blows upward subaerial dust and lead to polluting the indoor air, influences the risk that the user is healthy. The number of the air guide partition plates 4 is not limited too much, for example, in this embodiment, the number of the air guide partition plates 4 is two, and the two air guide partition plates 4 are respectively connected with the two side walls of the air duct 2, so that the manufacturing cost of the sweeping robot 100 is not excessively increased, and the air flow blown out from the air outlet 11 is more stable.

The inner walls of the air guide partition plate 4 and the air duct 2 can be selected to be bonded, clamped or welded with each other, preferably, in the embodiment, the air guide partition plate 4 and the air duct 2 are of an integrated structure, which is beneficial to improving the connection strength between the air guide partition plate 4 and the air duct 2, and can avoid the defects of burrs, wrinkles and the like at the joint of the air guide partition plate 4 and the air duct 2, which causes friction with air flow. Preferably, the sweeping robot 100 further comprises a cushioning plug 6. The cushioning plugging member 6 wraps the casing of the fan 3 and exposes the air inlet and the air outlet 11 of the fan 3. The cushioning plugging piece 6 can not only avoid the noise generated by the direct contact of the fan 3 with the inner wall of the air duct 2 during the vibration, but also plug the gap between the fan 3 and the air duct 2, thereby avoiding the backflow of the air flow in the air duct 2. The seismic block 6 is preferably, but not limited to, made of rubber or the like.

The side wall of the air duct 2 can be selected to be a straight wall or an arc wall. For example, in this embodiment, the lateral wall of the air duct 2 is in an arc shape, which further prolongs the length of the air duct 2, and makes the air outlet 11 and the side surface of the main body 1 form a certain included angle, which is helpful to enlarge the area of the air outlet 11 and make the air flow at the air outlet 12 more gentle. Preferably, the air inlet of the main body 1 is a circular hole, and the air outlet 11 is a square hole. The round smaller air inlet can facilitate the fan 3 to produce negative pressure in the air duct 2, and facilitate the outside air flow to carry the dust and sundries on the ground to be sucked into the air duct 2. When the air outlet 11 is set to be square, the area on the side surface of the main body 1 can be fully utilized, so that the area of the air outlet 11 can be set to be larger, the reduction of the wind speed in the air duct 2 is facilitated, the friction between the airflow and the outlet of the air duct 2 can be avoided, and the noise generated in the operation process of the sweeping robot 100 is further reduced.

In summary, the sweeping robot 100 of the present invention can overcome the defect of the prior art that the air duct 2 of the sweeping robot 100 has a relatively large noise, and can reduce the noise generated during the operation of the sweeping robot 100, which is helpful for improving the user experience.
