In this embodiment, the airflow chamber 1008 and the vacuum source 1009 of the cleaning robot are stacked and arranged on the chassis in the vertical direction, so that the space in the height direction of the cleaning robot is fully utilized, other core components can be more loosely arranged on the horizontal plane where the chassis is located, and the miniaturization and the intensification of the whole cleaning robot product are ensured.

In one embodiment of the present application, the cleaning robot further includes a fluid applicator storing fluid required for cleaning, the fluid applicator being not higher than an upper surface of the vacuum assembly. In this embodiment, the cleaning robot further includes a fluid applicator 1006, and the fluid applicator 1006 is not higher than the upper surface of the vacuum assembly, so that the height of the robot main body 1001 is not restricted by the fluid applicator 1006.

In one embodiment of the present application, the fluid applicator is "concave" comprising a bulge at both ends and a flat below the bulge; wherein an upper surface of the raised portions is not higher than an upper surface of the vacuum assembly, the flat portions are lower than a lower surface of the vacuum assembly, and the vacuum assembly is disposed between the raised portions. Referring to fig. 1-4 and 7, in this embodiment, the fluid applicator 1006 is "concave" in shape, including a ridge 1018 at both ends and a flat 1019 below the ridge 1018; wherein the upper surface of the ridges 1018 is no higher than the upper surface of the vacuum assembly and the flat portion 1019 is lower than the lower surface of the vacuum assembly, the vacuum assembly being disposed between the ridges 1018. By adopting the scheme in this embodiment, the height space of the robot main body 1001 can be more fully utilized, at least part of the fluid applicator 1006 is disposed below the vacuum assembly, and the vacuum assembly can be supported to a certain extent by the corresponding flat portion 1019, so that the stacked layout of the airflow chamber 1008, the vacuum source 1009 and the fluid applicator 1006 is realized, and the space of the robot main body 1001 in the horizontal direction is saved to the maximum extent.

In one embodiment of the present application, the fluid applicator further comprises a fluid injection port disposed on one of the ridges and a fluid discharge port disposed on the flat portion. Referring to fig. 2 and 7, in this embodiment, fluid applicator 1006 further includes a fluid inlet 1020 and a fluid outlet 1021, wherein the fluid inlet is disposed on one of ridges 1018 and the fluid outlet 1021 is disposed on a flat portion 1019. A fluid injection port 1020 is provided on the ridge 1018 to facilitate the user's addition of fluid to the fluid applicator 1006 from above; and fluid discharge port 1021 is disposed on lower level flat portion 1019 to facilitate adequate discharge of fluid from fluid applicator 1006.

In one embodiment of the present application, the vacuum source includes an airflow discharge port, and the fluid injection port is disposed on a corresponding ridge portion on a side adjacent to the airflow discharge port. Referring to fig. 7, in this embodiment, the vacuum source 1009 includes a gas flow vent 1022 and the fluid injection port 1020 is disposed on a corresponding ridge 1018 on a side adjacent the gas flow vent 1022. When a user adds fluid through the fluid injection port 1020, there may be a case where the fluid overflows or splashes, and if the robot main body 1001 is not sealed reliably enough, the corresponding fluid may be accumulated in the robot main body 1001, which may affect the normal operation of the cleaning robot electrical lines. With the solution of this embodiment, even if a small amount of fluid overflows or spills from the fluid inlet 1020, the fluid can be dried by the airflow discharged from the airflow outlet 1022, so that the possibility of damaging the electrical circuit of the cleaning robot by the fluid is greatly reduced.

In one embodiment of the present application, the cleaning robot further comprises a pad holder attached to the bottom of the robot body by an output shaft, and the corresponding output shaft is connected to a driving motor to rotate the pad holder around a shaft. In one embodiment of the present application, at least one of the output shafts is connected to the driving motor through a transmission assembly disposed below the vacuum assembly. Referring to fig. 1, 2 and 8, the cleaning robot in this embodiment further includes a pad holder 1011 attached to the bottom of the robot main body 1001 by output shafts 1012, wherein at least one output shaft 1012 is connected to a drive motor 1015 by a transmission assembly 1024, the transmission assembly 1024 being disposed below the vacuum assembly. In this embodiment, the vacuum assembly leaves room for the drive assembly 1024 below, and the corresponding vacuum assembly can be supported by both the fluid applicator 1006 and the drive assembly 1024, thereby more fully utilizing the height space of the robot body 1001 and enabling the pad holder 1011 to swivel.

In one embodiment of the present application, the cleaning robot further includes a fluid outlet port provided at a bottom of the robot main body and communicating with the fluid discharge port through a fluid line, the fluid outlet port being located inside the driving system. In this embodiment, the fluid outlet port 1007 is provided at the bottom of the robot main body 1001 and communicates with the fluid discharge port 1021 through the fluid line 1010, and the fluid outlet port 1007 is located inside the driving system 1002. In this embodiment, the driving system 1002 can block the fluid dropped or ejected from the fluid outlet 1007 from splashing to an area outside the robot main body 1001, so that the trajectory form formed by cleaning is more regular.

In one embodiment of the present application, a receiving cavity surrounded by a rib is vertically arranged around the driving system, and the fluid outlet is separated from the driving system by the corresponding rib. In this embodiment, a containing cavity 1023 surrounded by a barrier rib is vertically arranged around the driving system 1002, the fluid outlet 1007 is separated from the driving system 1002 by the barrier rib, and the corresponding barrier rib can prevent the fluid blown down by the air flow outlet 1022 from wetting the tread or the track surface of the driving system 1002, thereby effectively avoiding the slipping of the driving system 1002.

In one embodiment of the present application, the gas flow chamber is stacked above the vacuum source. In this embodiment, the gas flow chamber 1008 is stacked above the vacuum source 1009. However, from a space saving perspective, in other embodiments, the vacuum source 1009 may be stacked above the flow chamber 1008.

Referring to fig. 1 and 2, referring to a cleaning robot in an embodiment of the present application, there is disclosed a cleaning robot including: a robot main body 1001; the driving system 1002 is used for supporting the robot main body 1001 and driving the cleaning robot to walk, and the driving system 1002 is respectively arranged on two sides of the robot main body 1001; a vacuum assembly for creating a negative pressure to make the cleaning robot suck debris of a surface to be cleaned through a debris suction port 1004, the debris suction port 1004 being provided at the bottom of the robot body 1001 and communicating with the vacuum assembly; a cleaning pad 1005 disposed under the robot body 1001 for scrubbing a surface to be cleaned; the cleaning robot further includes a fluid applicator 1006, in which a fluid required for cleaning is stored, and the corresponding fluid is guided to a fluid exit port 1007 through a fluid line 1010 to wet a surface to be cleaned; the fluid exit port 1007 is disposed in the area between the two side drive systems 1002, and is located after the debris intake 1004 and before the cleaning pad 1005, the debris intake 1004 being open to the direction of travel of the cleaning robot. In this embodiment, vacuum components are disposed within robot body 1001, including airflow chamber 1008 and vacuum source 1009.

With the solution in this embodiment, the corresponding cleaning robot can clean the surface to be cleaned in a reasonable working sequence, i.e. firstly suck in dirty air above the surface to be cleaned through the vacuum assembly, then drop or eject the fluid required for cleaning through the fluid outlet 1007, and then wipe the wetted surface to be cleaned by the cleaning pad 1005, thereby completely cleaning the surface to be cleaned. Generally, fluid is dripped or sprayed from a fluid outlet and then impacts a corresponding surface to be cleaned, so that the fluid may splash, if the fluid is splashed to an area except the area below the cleaning robot, irregular water stains (such as burrs, radiation and the like) are formed around the cleaning robot, the cleaning robot cannot wipe the water stains at one time due to the fact that the corresponding water stains exceed the cleaning range of the cleaning pad, the cleaning robot is required to return to the area where the water stains are located for supplementary cleaning, otherwise, a leakage area is formed, and the regularity of a track form formed by cleaning is affected. In the cleaning robot in the embodiment, the driving systems 1002, the fluid outlet port 1007 and the cleaning pad 1005 are reasonably arranged, so that the fluid outlet port 1007 is just positioned in the region between the driving systems 1002, even if the fluid drops or is sprayed to the surface to be cleaned, the fluid drops are blocked by the driving systems 1002 at the two sides and do not exceed the region below the robot main body 1001 even if the fluid is splashed, and the formed water stains are all in the cleaning range of the cleaning pad 1005, so that the cleaning robot can wipe the cleaning pad cleanly at one time without reworking; meanwhile, the track form formed after the cleaning pad 1005 is wiped does not have irregular figures such as bur shapes and radial shapes, and regular track forms such as arch shapes can be left along the walking path of the cleaning robot, so that intelligent and ordered product experience is provided for users in sense.

In this embodiment, the debris suction port 1004 is opened toward the forward direction of the cleaning robot, so that fluid and liquid droplets are prevented from being sucked into the debris suction port 1004, and the debris and dust in the dirty air are effectively prevented from being wetted and becoming difficult to clean. In this embodiment, the forward direction of the cleaning robot, the width direction of which is perpendicular to the forward direction, is indicated by a large arrow in fig. 1. In one of the embodiments of the present application, the corresponding surface to be cleaned may be a floor or a glass surface, etc.

In this embodiment, the corresponding driving system 1002 is mainly illustrated by taking a driving wheel as an example, but those skilled in the art can understand that the corresponding driving system can also be implemented by selecting a crawler 1003 as shown in fig. 4.

In one embodiment of the present application, the cleaning robot has at least two of the fluid exit ports arranged along a width direction of the cleaning robot; the distance between the two fluid exit ports positioned on the outermost side is a first distance; the distance between the driving systems on the two sides is a second distance; the respective first distance is less than the second distance. In this embodiment, the cleaning robot has at least two fluid exit ports 1007, and the respective fluid exit ports 1007 are arranged along the width direction of the cleaning robot; the distance between the two fluid exit ports 1007 located on the outermost side is a first distance X1; the distance between the two side drive systems 1002 is a second distance X2; wherein the first distance X1 is less than the second distance X2. After the surface to be cleaned is subjected to the negative pressure action of the debris suction opening 1004, as the cleaning robot advances, the dirty air which is not sucked in forms floating dust behind the debris suction opening 1004, and in the embodiment, at least two fluid outlet openings 1007 are arranged behind the debris suction opening 1004, so that the falling fluid can adhere to the floating dust in the dirty air, carry the floating dust to the surface to be cleaned and then be wiped clean by the cleaning pad 1005, and therefore, the situation that the floating dust falls on the surface to be cleaned again to cause secondary pollution is avoided. In this embodiment, the number of the fluid outlet ports 1007 is at least two, and increasing the number of the fluid outlet ports 1007 helps to increase the probability of the fluid adhering to floating dust; meanwhile, the fluid exit port 1007 in this embodiment is arranged along the width direction of the cleaning robot, and the first distance X1 is smaller than the second distance X2, thereby ensuring that the fluid exit port 1007 is arranged in a region between the drive systems 1002, so that the drive systems 1002 can effectively block the splashing of the fluid.

In one embodiment of the present application, the cleaning robot further includes: a pad holder attached to the bottom of the robot body by an output shaft, the respective output shaft being connected to a drive motor to cause the pad holder to swivel about an axis; the cleaning pad is disposed below the pad holder and glides relative to the surface to be cleaned when revolving with the pad holder. In this embodiment, the cleaning robot further includes a pad holder 1011 attached to the bottom of the robot main body 1001 by an output shaft 1012, the output shaft 1012 being connected to a driving motor 1015 to rotate the pad holder 1011 around an axis; the cleaning pad 1005 is disposed below the pad holder 1011 and slides relative to the surface to be cleaned while revolving along with the pad holder 1011. As will be appreciated by those skilled in the art, the cleaning pad 1005 can be mounted on the pad holder 1011 in a variety of ways, such as adhesively, threadably, suspended, etc.; in addition, the pad holder 1011 is covered by the cleaning pad 1005, not specifically shown. As shown in FIG. 1, the pad holder in this embodiment is a rotatable disk that can be rotated in a plane parallel to the surface to be cleaned, thereby causing the cleaning pad 1005 to rotationally wipe the surface to be cleaned to enhance the cleaning effect. With the solution in this embodiment, the cleaning pad 1005 rotates back along with the pad holder 1011, and after the fluid used for wetting the surface to be cleaned is absorbed by the cleaning pad 1005, the corresponding fluid has a tendency to be thrown out by the centrifugal force, which also causes the formation of irregular water stains, thereby affecting the cleaning effect. Therefore, in this embodiment, it is more necessary to block the thrown fluid by the driving system 1002, and by adopting the scheme in this embodiment, repeated cleaning can be avoided, and the track form formed by cleaning is very regular, thereby greatly improving the product experience of the cleaning robot. On the other hand, in the conventional cleaning robot, the cleaning pad is often mounted below the robot main body by a non-active pad holder, and the fluid required for cleaning is directly guided to the fluid outlet port through the fluid pipe and directly permeates into the cleaning pad; however, in the embodiment of the present application, since the pad holder 1011 is in a high-speed rotation state during the operation, if the fluid is still directly applied to the cleaning pad 1005 through the fluid pipeline 1010 and the fluid outlet port 1007, the fluid pipeline 1010 may have extremely high design requirements, which may easily cause the fluid pipeline 1010 to be twisted during the rotation of the pad holder 1011. The cleaning robot in this embodiment applies fluid to the surface to be cleaned and then wipes the wetted surface to be cleaned with the cleaning pad 1005, thereby achieving cleaning while avoiding complicated plumbing difficulties. In addition, with the solution in this embodiment of the present application, the fluid can directly wet the surface to be cleaned without wetting the cleaning pad 1005 with the fluid and then cleaning the surface to be cleaned with the wetted cleaning pad 1005, thereby improving the cleaning efficiency.

In one embodiment of the present application, the cleaning robot has at least two pad holders arranged along a width direction of the cleaning robot; wherein, the distance between the axle centers of the two pad holders positioned at the outermost side is a third distance; the respective third distance does not exceed the first distance. In this embodiment, the cleaning robot has at least two pad holders 1011, the pad holders 1011 being arranged along the width direction of the cleaning robot; wherein, the distance between the axial centers of the two pad holders 1011 positioned at the outermost side is the third distance X3, and the third distance X3 does not exceed the first distance X1. In fig. 1, the third distance X3 is substantially equal to the first distance X1. In this embodiment, if the third distance X3 exceeds the first distance X1, the cleaning pad 1005 will occupy a larger space on the robot body 1011, which is not conducive to the arrangement of the cleaning pad 1005 and overall size control. In one embodiment of the present application, a distance between the fluid outlet located at the outermost side and the driving system at the side immediately adjacent to the fluid outlet is a fourth distance; wherein the respective fourth distance is less than a geometric radius of the cleaning pad. In this embodiment, the distance between the outermost fluid exit port 1007 and the drive system 1002 on the immediate side thereof is a fourth distance X4, wherein the fourth distance X4 is less than the geometric radius of the cleaning pad 1005. With the solution in this embodiment, the cleaning pad 1005 can be made to sufficiently cover the area behind the fluid exit port 1007, and an area wetted by the fluid but not wiped by the cleaning pad 1005 is prevented from being left after the cleaning robot passes the surface to be cleaned, thereby ensuring the cleaning thoroughness.

In one embodiment of the present application, the first distance does not exceed a width of the debris intake. Referring to fig. 1, in this embodiment, the first distance X1 does not exceed the width of the debris intake 1004 to ensure that dirty air has been drawn in by the debris intake 1004 in the area where fluid is dropped or ejected, thereby avoiding the area not covered by the debris intake 1004 from becoming too hard to clean by direct wetting with fluid. If the area not covered by the debris intake 1004 is directly wetted by the fluid, since the force applied to the surface to be cleaned when the fluid is dropped is primarily vertically downward, the corresponding force will cause the debris, dirt, and dust to adhere more tightly to the surface to be cleaned; whereas if the area not covered by the debris suction opening 1004 is indirectly wetted by wiping of the cleaning pad 1005, the direction of the force applied by the cleaning pad 1005 is primarily parallel to the surface to be cleaned, and the corresponding force further assists the cleaning pad 1005 in entraining debris, dirt, and dust away, thereby avoiding the area not covered by the debris suction opening 1004 from becoming directly wetted by the fluid and becoming difficult to clean.

In one embodiment of the present application, a first blocking portion is disposed on a side of the debris suction port close to the fluid outlet port, and the corresponding first blocking portion extends from the bottom of the robot body to the surface to be cleaned. Referring to fig. 1 and 3, in this embodiment, a first barrier 1013 is provided on a side of the debris suction port 1004 adjacent to the fluid outlet port 1007, and the corresponding first barrier 1013 extends from the bottom of the robot main body 1001 to the surface to be cleaned. In this embodiment, in order to prevent the swirling pad holder 1001 from throwing the fluid on the cleaning pad 1005 out to the debris suction port 1004 in front, causing the debris near the debris suction port 1004 to be wetted and become difficult to clean, a first barrier 1013 is provided at a side of the debris suction port 1004 close to the fluid outlet port 1007 to block the thrown-out fluid, so as to separate the suction area of the debris and the wetted area of the surface to be cleaned, and avoid interference therebetween.

In one embodiment of the present application, the debris suction port is provided with second blocking portions on both sides in the width direction, and the second blocking portions are engaged with the first blocking portions to half-surround the debris suction port. In this embodiment, the debris suction port 1004 is further provided with second partitions 1014 on both sides in the width direction, and the second partitions 1014 are engaged with the first partitions 1013 to half-surround the debris suction port 1004. In this embodiment, the first and second barriers 1013 and 1014 can block the debris from the area of the debris suction inlet 1004, and the first and second barriers 1013 and 1014 can form an opening in the forward direction of the cleaning robot and half-surround the debris suction inlet 1004, so that the flow guide function can be performed to guide the dirty air into the debris suction inlet 1004.

In one embodiment of the present application, the first blocking portion extends to abut against a surface to be cleaned, and an included angle between an extending direction of the first blocking portion and a forward direction of the cleaning robot is an acute angle. In this embodiment, the angle between the extending direction of the first partition 1013 and the advancing direction of the cleaning robot is an acute angle, so that the dirty air can more smoothly enter the debris suction inlet 1004 along the first partition 1013, and the first partition 1013 abuts against the surface to be cleaned, thereby ensuring the sealing property, and improving the air suction effect and the fluid blocking effect.

Referring to fig. 5, a cleaning robot in a further embodiment of the present application is referred to. The cleaning robot in this embodiment, which includes a robot body 4001, differs from the cleaning robot shown in fig. 1 in that only one fluid ejection port 4007 is provided and the cleaning pad 4005 is disposed on a non-active pad holder, i.e., the corresponding pad holder can travel only with the cleaning robot so as to slip relative to the surface to be cleaned, and the pad holder itself is not connected to a motor so that the corresponding pad holder is fixed relative to the robot body 4001. The pad holder in this embodiment is a flat plate-like holder. The fluid exit port 4007 in this embodiment is also located in the area between the two side drive systems 4002, behind the debris intake port 4004 and in front of the cleaning pad 4005. Since there is only one fluid ejection port 4007, in order to cover as much area as possible below the robot body 4001 with fluid, the corresponding fluid ejection port 4007 may employ a jet-type opening that distributes the ejected fluid in the width direction of the robot body 4001.

Referring to fig. 6, a schematic view of a cleaning pad of a cleaning robot in accordance with yet another embodiment of the present application is shown. It will be appreciated by those skilled in the art that in one of the embodiments of the present application, the cleaning robot may be provided with a plurality of pad holders 6011, and the shape of the corresponding pad holder 6011 may be selectable, such as a circle, a regular polygon, etc., and the shape of the cleaning pad corresponds to the pad holder 6011. As shown in fig. 6, the corresponding pad holder 6011 is a regular pentagon. In one embodiment of the present application, the third distance is 2(N-1) times the geometric radius of the cleaning pad, where N is the number of pad holders and N ≧ 2. In this embodiment, the distance between the axial centers of the two pad holders 6011 located on the outermost side is a third distance X3, where the third distance X3 is 2(N-1) times the geometric radius of the cleaning pad, where N is the number of pad holders 6011. As shown in fig. 6, 4 pad holders are provided so that the third distance X3 is 6 times the geometric radius of the cleaning pads, which ensures that the cleaning pads abut each other and prevents the formation of voids between the cleaning pads that can result in missed areas during cleaning.

All the embodiments in the present specification are described in a related manner, and the same and similar parts among the embodiments may be referred to each other, and each embodiment focuses on the differences from the other embodiments.

So far, the technical solutions of the present disclosure have been described in connection with the foregoing embodiments, but it is easily understood by those skilled in the art that the scope of the present disclosure is not limited to only these specific embodiments.
