In the cleaning robot of the embodiment of the present disclosure, the dust box 10 is disposed on the main body 20, and at least a portion of the position determining device 21 is disposed to protrude from the main body 20. Because the top end of the dust box 10 is not lower than the top end of at least part of the main body 20, and the top end of the position determining device 21 is higher than the top end of the dust box 10, on the basis of ensuring that the height of the dust box 10 is made high to the maximum extent, the position determining device 21 can be ensured to trigger the obstacle first, and therefore the dust box 10 or the main body 20 is indirectly protected from being blocked by the obstacle.

It should be noted that, since the top end of the dust box 10 is not lower than at least a part of the top end of the main body 20, the height of the dust box 10 is made as high as possible without changing the height of the original main body, so as to increase the dust collecting capability of the dust box 10 and to prevent the height of the cleaning robot.

In the disclosed embodiment, as shown in fig. 1 and 2, the main body 20 includes a top major plane 22, at least a portion of the position determining device 21 is disposed to protrude from the top major plane 22, and the top end of the dust box 10 is higher than the top major plane 22. The top main plane 22 is the upper large surface of the cleaning robot, and the positioning of at least part of the position determining means 21 protruding from the top main plane 22 ensures that the position determining means 21 reliably identifies obstacles. The fact that the top end of the dirt tray 10 is above the top major surface 22 ensures that the dirt tray 10 has sufficient dirt collecting capacity.

In the disclosed embodiment, as shown in fig. 1 and 2, the main body 20 further comprises a top convex plane 23, the top convex plane 23 being higher than the top main plane 22 and lower than the top end of the position determining device 21; wherein at least a portion of the dirt box 10 is located below the top raised plane 23. The top raised plane 23 is the upper small surface of the cleaning robot, and positioning the top end of the position determining means 21 higher than the top raised plane 23 ensures that the position determining means 21 reliably identifies obstacles. The dust box 10 is at least partially located below the top raised plane 23 to prevent the dust box 10 from having an excessively high height dimension for the cleaning robot, and the main body 20 also provides protection for the dust box 10.

In the disclosed embodiment, as shown in fig. 1 and 2, the main body 20 further includes a transition surface 24, the transition surface 24 connecting the top main plane 22 and the top convex plane 23; the top main plane 22 and the top protruding plane 23 are approximately parallel, and the transition plane 24 is inclined to the top protruding plane 23, so that the appearance design is attractive, the main body 20 can conveniently pass through short obstacles, and the cleaning robot is prevented from being locked. In particular, the transition surface 24 is effective to avoid that obstacles having a height between the top end of the position determining means 21 and said top main plane 22 will block the cleaning robot.

In the embodiment of the present disclosure, a portion of the dust box 10 is located below the top main plane 22, and a portion of the dust box 10 is located below the top protruding plane 23, so that a portion of the dust box 10 can be higher in height, which facilitates the arrangement of other structures, or a dust collecting space can be locally increased, and another portion of the dust box 10 can be adapted to the main height of the cleaning robot, and the main body 20 can effectively protect the dust box 10, thereby avoiding the occurrence of problems such as damage to the dust box 10.

As an alternative embodiment of the present disclosure, the top end of the position determining device 21 is higher than the top end of the dust box 10 by 0.2mm-10mm, which not only can ensure that the position determining device 21 triggers the obstacle first, but also can ensure that the height of the dust box 10 is relatively higher, which is beneficial to improving the dust collecting capability.

In the disclosed embodiment, the dust box 10 is located behind the position determining device 21 in the cleaning running direction of the cleaning robot. The position determining device 21 is located at the middle position of the cleaning robot, and the dust box 10 is located at the rear of the cleaning robot, the vertical projection of the position determining device 21 and the dust box 10 may have no overlapping area, so that the height of at least a part of the dust box 10 may be made larger than the top main plane 22 regardless of the interference of the position determining device 21 with the dust box 10, whereby the height of the dust box 10 may be further ensured.

The cleaning robot that this disclosed embodiment provided for cooperate with clean basic station, with the dust of discharging in it into clean basic station, cleaning robot includes: the dust storage cavity (11) is provided with a dust storage cavity, the dust storage chamber 11 includes an opening; the door body 12, the door body 12 is movably arranged relative to the dust storage cavity 11, in order to release or shelter from the opening; after the cleaning robot is in butt joint with the cleaning base station, the door body 12 can release the opening, so that the opening is communicated with a dust inlet of the cleaning base station.

The dust storage cavity 11 in the embodiment of the present disclosure may be formed by the main body 20, that is, a cavity is formed inside the main body 20, and the cavity is used for collecting dust, so as to be used as the dust storage cavity 11, and the door 12 may be disposed on the main body 20, so as to shield the opening of the dust storage cavity 11 and prevent dust from leaking, and when the dust in the dust storage cavity 11 is discharged, the door 12 may be opened to release the opening of the dust storage cavity 11, so as to discharge the dust in the dust storage cavity 11, for example, the dust in the dust storage cavity 11 is discharged into a clean base station.

The dust storage cavity 11 in the embodiment of the present disclosure may be formed by the dust box 10 on the main body 20, the dust box 10 is disposed on the main body 20, the dust box 10 and the main body 20 constitute a robot body, and the door 12 is disposed on the dust box 10, so as to release or shield an opening of the dust storage cavity 11.

The dust box 10 provided by the embodiment of the present disclosure includes a dust storage cavity 11, and the dust storage cavity 11 includes: a first chamber 111, the first chamber 111 comprising a waste inlet 1112; a second chamber 112, the second chamber 112 comprising an exhaust port 1123; a transition passage 113, the first chamber 111 communicating with the second chamber 112 through the transition passage 113.

Referring to fig. 7 to 16, the dust box 10 of the embodiment of the disclosure includes a first chamber 111 and a second chamber 112 which are independently disposed, and the first chamber 111 is communicated with the second chamber 112 through a transition passage 113, so that the primary separation of dust in the first chamber 111 can be achieved, thereby reducing the probability of the dust blocking the transition passage 113, and reliably achieving the collection of dust, so as to improve the dust collecting capability of the dust box 10.

Dust entering from the cleaning module 30 enters the first chamber 111 through the dust inlet 1112 for preliminary separation and enters the second chamber 112 through the transition passage 113, so that the dust is effectively recovered, and the filtered air is discharged out of the dust box 10 through the exhaust port 1123.

In the embodiment of the present disclosure, the transition channel 113 is approximately tangential to the second chamber 112, so that dust can reliably enter the second chamber 112 from the transition channel 113, and the gas flow can be facilitated, thereby improving the flowability of the dust in the dust storage cavity 11 and improving the dust collecting capability of the dust box 10.

As an alternative embodiment of the present disclosure, the transition passage 113 is approximately tangential to the first chamber 111, so that dust can reliably enter the transition passage 113 from the first chamber 111, and the gas flow is facilitated, thereby improving the flowability of the dust in the dust storage cavity 11.

The cyclone separator 13 is arranged in the second chamber 112, and the gas entering the second chamber 112 tangentially can be separated into fine dust and gas through the cyclone separator 13, so that the cleanliness of the filter screen is ensured. The cyclone separator 13 may be a cyclone cone.

In the disclosed embodiment, the side wall of the transition passage 113 includes a curved surface, so that the dust can smoothly flow in the transition passage 113, thereby avoiding the problems of dust blockage and the like.

In the embodiment of the present disclosure, the extension length of the transition channel 113 is greater than the minimum wall thickness between the first chamber 111 and the second chamber 112, so that the time for the airflow to pass through the transition channel 113 carrying dust can be relatively long, thereby avoiding the problem of blocking the transition channel 113 caused by accumulation of a large amount of dust.

It should be noted that the extension length of the transition channel 113 can be considered as the distance that the airflow flows in the transition channel 113, and the first chamber 111 and the second chamber 112 are blocked by the wall surface of the dust box 10, so that the extension length of the transition channel 113 is greater than the minimum wall thickness between the first chamber 111 and the second chamber 112, which can avoid the problem that the transition channel 113 is blocked due to the accumulation of dust.

In the embodiment of the present disclosure, the door 12 is rotatably disposed on the dust box 10, so that the door 12 can be conveniently released or shielded from the opening of the dust storage cavity 11.

The door 12 can be coupled to a drive mechanism to drive the door 12 to rotate relative to the dust box 10. Or, after the cleaning robot is docked with the cleaning base station, the door 12 may drive the door 12 to open or close through the airflow generated by the fan assembly 40 of the cleaning robot. Or, after the cleaning robot is docked with the cleaning base station, the door body 12 may drive the door body 12 to open or close through the suction force generated by the power assembly of the cleaning base station.

In the disclosed embodiment, at least a portion of the dust box 10 is located outside the main body 20, so that when the door body 12 releases the opening, the opening can be directly communicated with the dust inlet, so that the dust in the dust box 10 can be conveniently discharged into the cleaning base station.

After the door body 12 releases the opening, a part of the door body 12 can extend into the inner side of the dust inlet for storage, so that the opening of the dust storage cavity 11 is reliably butted with the dust inlet, and dust can be effectively collected into the cleaning base station.

The dust box 10 and the main body 20 form at least a portion of an outer surface of the cleaning robot, so that the dust box 10 is directly docked with the cleaning base station after the cleaning robot is docked with the cleaning base station, and thus the opening of the dust storage cavity 11 can be securely docked with the dust inlet after the door body 12 is opened.

In the embodiment of the disclosure, as shown in fig. 11 to 13, the dust storage cavity 11 includes a first cavity 111 and a second cavity 112, and the door 12 selectively releases the first cavity 111 and the second cavity 112, so that the first cavity 111 and the second cavity 112 can be selectively communicated with the dust inlet, thereby realizing the staged discharge of dust in the dust storage cavity 11, avoiding the problems of blockage and the like when a large amount of dust is discharged, and improving the dust collection efficiency.

The first chamber 111 and the second chamber 112 may be independently disposed, so that dust may be stored in both the first chamber 111 and the second chamber 112, but the dust in the first chamber 111 and the second chamber 112 may be dust in different stages, for example, during a cleaning process of a cleaning robot, the dust first enters the first chamber 111, and then a part of the dust enters the second chamber 112, and therefore, the sizes of dust particles in the first chamber 111 and the second chamber 112 may not be the same.

It should be noted that the cyclone separator 13 may be a cyclone separator known in the related art, the working principle of the cyclone separator is that the cyclone separator depends on the rotational motion caused by the tangential introduction of the gas flow, and the centrifugal force is much larger than the gravity when the particles rotate at high speed in the gas flow, and the centrifugal settling velocity obtained by the particles is also larger because of the larger velocity, when the particles containing solid state enter the conical cylinder along the direction of the gas autotangent line and rotate in the cylinder, at this time, the gas flow collides with the wall of the cylinder, the particles collide with the wall of the cylinder and rotate and descend, thereby achieving the purpose of separating the solid from the gas.

In the cleaning robot provided by the embodiment of the present disclosure, the cleaning module 30 is disposed on the main body 20, and the cleaning module 30 cleans a surface to be cleaned.

In the disclosed embodiment, the cleaning module 30 may be a dry cleaning module and the dry cleaning system may include a roller brush. The roller brush, which has some interference with the floor, sweeps and rolls the debris on the floor in front of the debris inlet 1112 between the roller brush and the dust box 10, and then is drawn into the dust box 10 by the suction air generated by the fan assembly 40 and passing through the dust box 10. The Dust removing capability of the cleaning robot can be represented by the cleaning efficiency (DPU) of the garbage, and the cleaning efficiency DPU is influenced by the structure and the material of the rolling brush, the wind power utilization rate of an air duct formed by the garbage inlet 1112, the Dust box 10, the fan 41, the air outlet and connecting parts among the four, the type and the power of the fan, and the cleaning robot is a complicated system design problem. Compared with the common plug-in dust collector, the improvement of the dust removal capability has greater significance for cleaning automatic cleaning equipment with limited energy. Because the improvement of the dust removal capability directly and effectively reduces the energy requirement, namely the machine which can clean the ground of 80 square meters by charging once can be developed into the machine which can clean 180 square meters or more by charging once. And the service life of the battery with reduced charging times is greatly increased, so that the frequency of replacing the battery by a user is reduced. More intuitively and importantly, the improvement of the dust removal capability is the most obvious and important user experience, and the user can directly draw a conclusion whether the sweeping/wiping is clean. The cleaning robot may also include an edge brush 37 having an axis of rotation that is angled relative to the floor for moving debris into the brush roll area of the cleaning system.

As an alternative embodiment of the present disclosure, the cleaning module 30 may be a wet cleaning module, the wet cleaning module may include a wet cleaning head, and the cleaning module 30 further includes a liquid supply portion, the liquid supply portion sends the cleaning liquid to the wet cleaning head, so that the wet cleaning head performs wet cleaning on the plane to be cleaned. In other embodiments of the present disclosure, the cleaning liquid inside the liquid supply portion may also be directly sprayed to the plane to be cleaned, and the wet cleaning head cleans the plane by uniformly smearing the cleaning liquid.

Wherein the cleaning head is for cleaning a surface to be cleaned and the drive system 50 is for driving the cleaning head in a substantially reciprocating motion along a target surface, which is a portion of the surface to be cleaned. The cleaning head reciprocates along the surface to be cleaned, cleaning cloth or a cleaning plate is arranged on the surface of the contact surface of the cleaning head and the surface to be cleaned, and high-frequency friction is generated between the cleaning head and the surface to be cleaned through reciprocating motion, so that stains on the surface to be cleaned are removed. The cleaning head may be a floor brush.

The higher the friction frequency, the more the friction times in unit time, the high-frequency reciprocating motion, also called reciprocating vibration, the cleaning capacity is much higher than that of the common reciprocating motion, such as rotation and friction cleaning, and optionally, the friction frequency is close to the sound wave, and the cleaning effect is much higher than that of the rotation friction cleaning of dozens of circles per minute. On the other hand, the hair tufts on the surface of the cleaning head can extend towards the same direction more neatly and neatly under the shaking of high-frequency vibration, so that the overall cleaning effect is more uniform, the whole cleaning effect is not improved by only applying downward pressure to increase the friction force under the condition of low-frequency rotation, the multiple groups of hair tufts cannot extend towards the same direction only by the downward pressure, and the effect is that the water marks on the surface to be cleaned after the high-frequency vibration cleaning are more uniform, and the disordered water marks cannot be left.

The reciprocating motion may be a reciprocating motion in any one or more directions within the surface to be cleaned, or may be a vibration perpendicular to the surface to be cleaned, which is not strictly limited. Alternatively, the reciprocating direction of the cleaning module is approximately perpendicular to the machine traveling direction, because the reciprocating direction parallel to the machine traveling direction may cause instability to the traveling machine itself, because the driving wheel may easily slip due to thrust and resistance in the traveling direction, the effect of slipping is more obvious in the case of including a wet cleaning module, because the wet slipping of the surface to be cleaned increases the possibility of slipping, and slipping may cause inaccurate distance measurement of sensors such as a odometer and a gyroscope besides affecting smooth traveling cleaning of the machine, thereby causing inaccurate positioning and mapping of the navigation type automatic cleaning device, and in the case of frequent slipping, the effect on SLAM may not be ignored, and therefore, the machine behavior of slipping needs to be avoided as much as possible. In addition to slippage, the component of the cleaning head motion in the direction of machine travel causes the machine to be constantly propelled forward and backward while traveling, and thus the machine travels erratically and smoothly.

Since at least part of the cleaning module 30 is movably disposed up and down relative to the main body 20, and the cyclone separator 13 is disposed, the current of the cleaning robot is not too large during the cleaning process, and the cleaning time of the cleaning robot can be increased.
