In one embodiment, the first dust collecting member 200 and the second dust collecting member 300 are independent from each other.

Specifically, the first dust collecting member 200 collects the objects to be cleaned, which are rotatably swept by the cleaning assembly 100, and the second dust collecting member 300 collects the objects to be cleaned, which are adsorbed by the cleaning assembly 100, to form two independent dust collecting devices.

Preferably, the first dust collecting part 200 and the second dust collecting part 300 are detachably connected to the body 10, so as to facilitate the treatment of the objects to be cleaned inside the first dust collecting part 200 and the second dust collecting part 300, and to facilitate the cleaning of the first dust collecting part 200 and the second dust collecting part 300, and in addition, the cleaning robot can collect the objects to be cleaned only by the rotation of the cleaning assembly 100 without providing the second dust collecting part 300.

In another embodiment, the first dust collecting member 200 communicates with the second dust collecting member 300, and the first dust collecting member 200 is located at an upstream position of the second dust collecting member 300.

Specifically, the first dust collecting member 200 collects the object to be cleaned which the cleaning assembly 100 is rotated to sweep; the second dust collecting member 300 collects the objects to be cleaned adsorbed by the cleaning assembly 100, and simultaneously, the objects to be cleaned inside the first dust collecting member 200 are also adsorbed by the second dust collecting member 300 and enter the second dust collecting member 300, so that the objects to be cleaned are finally collected inside the second dust collecting member 300, and centralized cleaning is facilitated.

Preferably, the first dust collecting part 200 and the second dust collecting part 300 are detachably connected to the body 10, so as to facilitate the treatment of the objects to be cleaned inside the first dust collecting part 200 and the second dust collecting part 300, and also facilitate the cleaning of the first dust collecting part 200 and the second dust collecting part 300.

Specifically, during the rotary sweeping process of the cleaning assembly 100, the cleaning assembly 100 sweeps the object to be cleaned from the surface to be cleaned into the dust collecting opening and into the first dust collecting member 200 in sequence.

As shown in fig. 3 and 10, the bottom plate 201 includes an inclined plate section 2011 and a collecting plate section 2010 arranged in this order, the inclined plate section 2011 is close to the dust collecting opening with respect to the collecting plate section 2010, and the inclined plate section 2011 extends obliquely upward in a direction close to the collecting plate section 2010; collecting plate segment 2010 has a sunken groove therein for collecting the object to be cleaned by cleaning assembly 100 through inclined plate segment 2011 to the interior of the sunken groove.

Specifically, the bottom plate 201 is designed to be inclined, so that the end of the inclined plate 2011 of the bottom plate 201 facing the dust collecting opening is close to and not in contact with the surface to be cleaned, thereby preventing the first dust collecting part 200 from rubbing the surface to be cleaned and affecting the movement of the machine body 10.

Further, the first dust collecting member 200 may be floatingly disposed.

It should be noted that the objects to be cleaned proceed along the inclined plate 2011 to the inside of the recess of the collecting plate 2010 to avoid the objects to be cleaned from falling again to the outside of the first dust collecting member 200 when the first dust collecting member 200 moves following the machine body 10.

As shown in fig. 10, a mounting plate is disposed on a side of the enclosing plate 202 facing the inside of the first dust collecting member 200, one end of the mounting plate is connected to the enclosing plate 202, and the other end of the mounting plate extends toward a direction close to the center line of the bottom plate 201, i.e., the other end of the mounting plate extends toward the center of the first dust collecting member 200, the mounting plate is designed to be inclined with respect to the enclosing plate 202, and an included angle is formed between the mounting plate and the enclosing plate 202, and the included angle is an acute angle.

Specifically, comb teeth 400 are provided on the end surface of the mounting plate facing the bottom surface 11 of the housing, and the inclination angle or radian of the comb teeth 400 is adapted to the movement path of the cleaning assembly 100. The comb teeth 400 have a function of separating the object to be cleaned wound on the cleaning assembly 100 by the comb teeth 400 when the cleaning assembly 100 is wound with a flexible object during the cleaning operation of the cleaning robot.

Further, when the object to be cleaned is hair or other objects easily wound around the cleaning arm 103, the cleaning assembly 100 cannot sweep the object to be cleaned into the first dust collecting part 200, and at this time, the cleaning assembly 100 rotates to contact the surrounding plate 202, and the comb teeth 400 on the surrounding plate 202 cut off the hair, so that the hair can be smoothly dropped from the cleaning arm 103 and can be swept into the first dust collecting part 200 by the cleaning assembly 100.

Further, sharp structures such as blades can be disposed on the enclosure 202 to cut off and cut off objects wound or stuck on the cleaning arm 103, so as to facilitate cleaning or adsorption treatment.

Further, the enclosure 202 is not limited to mounting the comb 400 and the blades, but may have other structures that can separate and collect the cleaning object remaining on the cleaning assembly 100.

As shown in fig. 10, the shroud 202 includes a first side plate section 2021, a rear plate section 2023, and a second side plate section 2022, which are connected in sequence, wherein an end of the first side plate section 2021 away from the rear plate section 2023 and an end of the second side plate section 2022 away from the rear plate section 2023 jointly form a dust collecting opening, and heights of the first side plate section 2021 and the second side plate section 2022 are gradually increased along a direction approaching the rear plate section 2023, so that an avoiding gap is formed between a top surface of the first side plate section 2021 and a top surface of the second side plate section 2022 and the bottom surface 11 of the machine body, respectively, and the avoiding gap is used for avoiding the cleaning assembly 100.

Specifically, the enclosing plate 202 is provided with a gap between the position facing the dust collecting opening and the bottom surface 11 of the housing, the cleaning arm 103 rotates along with the rotating shaft 101 to collect the object to be cleaned from the surface to be cleaned into the first dust collecting member 200, and the cleaning arm 103 passes through the gap during the rotation of the cleaning arm 103, so that the blocking phenomenon between the cleaning arm 103 and the enclosing plate 202 can be avoided.

Further, the first side plate section 2021 and the second side plate section 2022 are vertically disposed and mounted on the bottom plate 201.

In an embodiment, not shown, the first side plate section 2021 and the second side plate section 2022 may also be disposed at an angle to the vertical direction, and one end of the first side plate section 2021 and the second side plate section 2022 is connected to the bottom plate 201, and the other end extends toward or away from the center of the first dust collecting part 200, so that the first side plate section 2021 and the second side plate section 2022 are both disposed obliquely.

Specifically, when one end of the first side plate section 2021 and the second side plate section 2022 is connected to the bottom plate 201, and the other end extends toward the center of the first dust collecting element 200, the problem that the first side plate section 2021 and the second side plate section 2022 cannot be completely connected to the bottom surface 11 of the housing due to the overlong bottom plate 201 of the first dust collecting element 200 can be avoided; when one end of the first and second

side plate sections

2021 and 2022 is connected to the base plate 201 and the other end extends away from the center of the first dust collecting part 200, the collecting space of the first dust collecting part 200 is increased.

Furthermore, a baffle plate for blocking the first channel 102 is arranged at one end of the rotating shaft 101 facing the surface to be cleaned, so that the object to be cleaned flows in a single direction after entering the first channel 102 from the dust suction channel.

Specifically, the cleaning assembly 100 has a rotating shaft 101 and a cleaning member, the rotating shaft 101 has a first channel 102, the cleaning member has one or more cleaning arms 103, and the cleaning arms 103 have dust suction channels communicating with the first channel 102. The rotating shaft 101 rotates to rotate the cleaning arm 103, and the first passage 102 and the dust suction passage cooperate to form a dust collection passage. The cleaning device can clean the object to be cleaned by rotating the cleaning arm 103, and can also utilize the dust suction channel to adsorb and collect the object to be cleaned on the surface to be cleaned, or can perform the rotating cleaning and the adsorbing and collecting simultaneously.
