The technical solution in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application:

referring to fig. 1 and 2, an embodiment of the present application relates to a suction and mopping integrated cleaning robot, and the embodiment discloses a suction and mopping integrated cleaning robot, including: a robot main body 1001; the driving system 1002 is used for supporting the robot main body 1001 and driving the suction and mopping integrated 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 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 suction and mopping integrated cleaning robot further comprises a fluid applicator 1006, in which fluid required for cleaning is stored, and the corresponding fluid is guided to a fluid exit port 1007 through a fluid pipeline 1010 to wet the surface to be cleaned; the fluid outlet port 1007 is provided in a region below the robot main body 1001 between the debris suction port 1004 and the cleaning pad 1005; wherein the debris suction opening 1004 sucks air inward toward the forward direction of the suction and mopping integrated cleaning robot, and the fluid discharged from the fluid discharge opening 1007 toward the surface to be cleaned is out of the axial projection range of the debris suction opening 1004.

With the solution in this embodiment, the corresponding suction and mopping integrated cleaning robot can clean the surface to be cleaned in a reasonable working sequence, that is, firstly, the vacuum assembly sucks in dirty air above the surface to be cleaned, then the fluid required for cleaning is dropped or ejected from the fluid exit port 1007, and then the cleaning pad 1005 wipes the wetted surface to be cleaned, thereby completely cleaning the surface to be cleaned. Usually, the fluid is dripped or sprayed from the fluid outlet and then impacts the corresponding surface to be cleaned, which may cause splashing of the fluid, if the fluid is splashed to an area other than the area below the suction and mop integrated cleaning robot, irregular water stains (such as bur-shaped and radial) are formed around the suction and mop integrated cleaning robot, and the corresponding water stains exceed the cleaning range of the cleaning pad, so that the suction and mop integrated cleaning robot cannot clean the water stains at one time, and the suction and mop integrated cleaning robot is often 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 the track form formed by cleaning is affected. In the cleaning robot with suction and mopping integrated functions in the embodiment, the driving system 1002, the fluid outlet 1007 and the cleaning pad 1005 are reasonably arranged, so that the fluid outlet 1007 is just surrounded by the core components such as the debris suction inlet 1004 and the cleaning pad 1005, and after the fluid drops or is sprayed to the surface to be cleaned, even if sputtering occurs, the rising liquid beads are blocked by the driving systems 1002 at the two sides, the debris suction inlet 1004 at the front side and the cleaning pad 1005 at the rear side and cannot exceed the area below the robot main body 1001, and the water stains formed in the way are all in the cleaning range of the cleaning pad 1005, so that the cleaning robot with suction and mopping integrated functions can clean at one time without rework of the cleaning robot with suction and mopping integrated functions; 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 a regular track form such as a bow shape can be left along the walking path of the suction and mopping integrated cleaning robot, so that intelligent and ordered product experience is provided for users in sense. In this embodiment, the debris suction inlet 1004 draws air inward in the forward direction of the integrated suction and mopping cleaning robot, and the fluid discharged from the fluid outlet 1007 is outside the axial projection range of the debris suction inlet 1004, so that the risk of the corresponding fluid entering the debris suction inlet 1004 is greatly reduced, the area within the action range of the debris suction inlet 1004 can be kept dry, and interference between the suction and mopping functions is avoided.

In this embodiment, the debris suction inlet 1004 forms a projected area on the surface to be cleaned by an axial projection, and the fluid discharged from the fluid outlet port 1007 toward the surface to be cleaned does not pass through a space above the corresponding projected area, so that the corresponding fluid falls behind the surface to be cleaned outside the axial projection range of the debris suction inlet 1004. In this embodiment, in order to make the fluid discharged from the fluid outlet port 1007 to the surface to be cleaned out of the axial projection range of the debris suction port 1004, the fluid outlet port 1007 can discharge the fluid to the surface to be cleaned in a dripping manner by virtue of the gravity applied to the fluid; alternatively, the fluid outlet 1007 may discharge the fluid to the surface to be cleaned by spraying, and the spraying angle of the fluid outlet 1007 is set properly, so that the discharged fluid does not pass through the area corresponding to the axial projection of the debris suction port 1004, thereby preventing the debris and dust in the dirty air from being wetted and becoming difficult to clean. In this embodiment, the forward direction of the suction and mopping integrated cleaning robot is indicated by a large arrow in fig. 1, and the width direction of the suction and mopping integrated cleaning robot is perpendicular to the forward direction. 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 one embodiment of the present application, one side of the debris intake proximate to the fluid exit port is closer to the surface to be cleaned than the other side. In this embodiment, one side (which is blocked by the first blocking part 1013 in fig. 1) of the debris suction inlet 1004 close to the fluid outlet 1007 is closer to the surface to be cleaned than the other side, so that the debris suction inlet 1004 is sucked inward in the forward direction of the integrated suction and mopping cleaning robot to avoid interference of suction and mopping functions. Wherein the arrows in fig. 3 indicate the flow trend of the dirty air, the airflow path at the section of the debris suction inlet 1004 is inclined forward to match the debris suction inlet 1004 to draw air inward toward the forward direction of the integrated suction and suction cleaning robot.

In one embodiment of the present application, the fluid exit port is closer to the cleaning pad than the debris intake port. This embodiment, the fluid exit port 1007 is closer to the cleaning pad 1005 than the debris suction port 1004, so that the fluid exiting the fluid exit port 1007 is more difficult to reach the debris suction port 1004, preventing debris and dust in the dirty air from being wetted and becoming difficult to clean. And the fluid exit port 1007 is closer to the cleaning pad 1005, the splashed fluid is more easily absorbed in close proximity by the cleaning pad 1005, thereby increasing the wetting rate of the cleaning pad 1005.

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 application, the suction-and-drag integrated cleaning robot is provided with at least two fluid outlet ports, and the fluid outlet ports are arranged along the width direction of the suction-and-drag integrated 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 suction and mopping integrated cleaning robot has at least two fluid exit ports 1007, and the corresponding fluid exit ports 1007 are arranged along the width direction of the suction and mopping integrated cleaning robot; the distance between the two fluid exit ports 1007 located on the outermost sides is a first distance X1; the distance between the two side driving 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 of the debris suction opening 1004, as the suction and mopping integrated 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 floating dust is prevented from falling on the surface to be cleaned again to cause secondary pollution. 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 ports 1007 in this embodiment are arranged along the width direction of the suction and drag integrated cleaning robot, and the first distance X1 is smaller than the second distance X2, thereby ensuring that the fluid exit ports 1007 are arranged in the region between the driving systems 1002, so that the driving systems 1002 can effectively block the splashing of the fluid.

In one embodiment of the present application, the suction and mopping integrated 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 slips relative to the surface to be cleaned when revolving with the pad holder. In this embodiment, the suction and mopping integrated cleaning robot further comprises a pad holder 1011 attached to the bottom of the robot main body 1001 through an output shaft 1012, the output shaft 1012 is connected with a driving motor 1015 to drive the pad holder 1011 to rotate around a shaft; the cleaning pad 1005 is disposed below the pad holder 1011 and slips 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 may 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 bringing 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-out fluid by the driving system 1002, and by adopting the scheme in this embodiment, repeated cleaning can be avoided, the track form formed by cleaning is very regular, and the product experience of the suction and mopping integrated cleaning robot is greatly improved. On the other hand, in the conventional suction and mopping integrated cleaning robot, the cleaning pad is often arranged below the robot body through a non-active pad holder, and the fluid required for cleaning is directly guided to the fluid outlet port through a fluid pipeline 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 suction and mopping integrated cleaning robot in this embodiment applies fluid to the surface to be cleaned, and then the cleaning pad 1005 wipes the wetted surface to be cleaned, so that the cleaning purpose is achieved while the complicated pipeline design problem is avoided. 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 suction and mopping integrated cleaning robot has at least two pad holders, which are arranged along a width direction of the suction and mopping integrated 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 suction and mopping integrated cleaning robot has at least two pad holders 1011, and the pad holders 1011 are arranged along the width direction of the suction and mopping integrated cleaning robot; wherein the distance between the axial centers of the two pad holders 1011 located at the outermost sides is a 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 of the robot main body 1011, which is not favorable for the arrangement of the cleaning pad 1005 and the overall dimension 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 outlet port 1007, so as to avoid leaving an area wetted by the fluid and not wiped by the cleaning pad 1005 after the suction and drag of the integrated cleaning robot across the surface to be cleaned, thereby ensuring the completeness of cleaning.

In one of the embodiments of the present application, the interface between the pad holders is located behind the drive system. Referring to fig. 1, in this embodiment, cleaning pads 1005 are tangent to each other, with the corresponding interface located behind drive system 1002. In this embodiment, the interface between the cleaning pads 1005 is located behind the drive system 1002, which helps to confine the majority of the fluid thrown off by the cleaning pads 1005 to the region between the leading edge and the trailing edge of the drive system 1002, depending on the direction of the centrifugal force, and thus is blocked by the drive system 1002. If the interface between the cleaning pads 1005 is too forward, there is a greater chance that the flung fluid will reach the debris intake 1004, and the area spaced from the debris intake and the drive system 1002, beyond the leading edge of the drive system 1002, thereby affecting the anti-splash effect.

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 difficult to clean by direct wetting with fluid. If the area not covered by the debris suction inlet 1004 is directly wetted by the fluid, the corresponding force will cause the debris, dirt, and dust to adhere more tightly to the surface to be cleaned since the force applied to the surface to be cleaned when the fluid is dropped is primarily vertically downward; 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, which causes 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 from interfering with each other; meanwhile, the first blocking part 1013 is also matched with the debris suction port 1004 to achieve the purpose of sucking air inwards towards the advancing direction of the integrated cleaning robot.

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 barrier 1013 and the second barrier 1014 can block the debris from the area of the debris suction inlet 1004, and the first barrier 1013 and the second barrier 1014 are disposed around the debris suction inlet 1004 in a half-surrounded manner and form an opening in the forward direction of the integrated suction and mopping cleaning robot, so that the flow guiding function is also provided, and the dirty air can be guided 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 suction and dragging integrated cleaning robot is an acute angle. In this embodiment, an angle between the extending direction of the first blocking portion 1013 and the advancing direction of the cleaning robot is an acute angle, so that the dirty air can enter the debris suction port 1004 more smoothly along the first blocking portion 1013, and the first blocking portion 1013 abuts against the surface to be cleaned to ensure the sealing performance, and improve the air suction effect and the fluid blocking effect.

Referring to fig. 5, a suction and mopping integrated cleaning robot in yet another embodiment of the present application is referred to. The suction-mopping integrated cleaning robot in this embodiment includes a robot main body 4001, and unlike the suction-mopping integrated cleaning robot shown in fig. 1, there is only one fluid ejection port 4007 and its cleaning pad 4005 is provided on a non-active pad holder, i.e., the corresponding pad holder can travel only along with the suction-mopping integrated cleaning robot to slip relative to the surface to be cleaned, and the pad holder itself is not connected to a motor, so the corresponding pad holder is fixed relative to the robot main 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 of the fluid as possible below the robot body 4001, 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 suction and mopping integrated cleaning robot is referred to in a further embodiment of the present application. As will be understood by those skilled in the art, in one of the embodiments of the present application, the suction and mopping integrated cleaning robot may be provided with a plurality of pad holders 6011, and the shape of the corresponding pad holder 6011 is 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, which can lead to the formation of missing areas during cleaning.

Referring to fig. 7, a suction and mopping integrated cleaning robot in still another embodiment of the present application is concerned. The suction and mopping integrated cleaning robot in the embodiment has a circular roller type pad holder, and a cleaning pad 7005 is at least partially arranged below the pad holder; in addition, a plurality of fluid ejection ports 7007 are provided for the suction and mopping integrated cleaning robot.

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. The technical solutions in the above embodiments can be split and combined, and equivalent changes or substitutions can be made on related technical features by those skilled in the art without departing from the technical principles of the present disclosure, and any changes, equivalents, improvements, and the like made within the technical concept and/or technical principles of the present disclosure will fall within the protection scope of the present disclosure.
