DETAILED DESCRIPTION

[0044] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure.

[0045] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0047] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0048] The specific embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0049] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0050] In this article, "first", "second", etc. are only used to distinguish each other, and do not indicate the importance and order, or the prerequisite for each other's existence.

[0051] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0052] The present disclosure provides a cleaning robot that can be used in home or commercial settings. The cleaning robot can be a window cleaning robot for cleaning windows or glass exterior walls. The cleaning robot provided by the present disclosure includes a body and a liquid storage device. The body is configured to move on a work surface and has a first motion posture that moves in a height direction on the work surface and a second motion posture that moves in a horizontal direction on the work surface. The first motion posture is when the cleaning robot moves in an upward or downward direction on the work surface, and the second motion posture is when the cleaning robot moves in a left or right direction on the work surface.

[0053] A liquid storage device is disposed within the body, containing cleaning liquid. When the cleaning robot is operating, the cleaning liquid in the liquid storage device is used to clean the work surface. Furthermore, the liquid storage device is provided with a first water outlet and a second water outlet, both of which are in communication with the liquid storage device. Cleaning liquid in the liquid storage device is discharged through the first and second water outlets to clean the work surface. A baffle device is disposed within the liquid storage device adjacent to the first water outlet, enclosing the first water outlet to form a cavity. The cavity has an open end, and the first water outlet is in communication with the inner cavity of the liquid storage device through the open end.

[0054] When the body is in the first motion posture, that is, when the cleaning robot moves upward or downward on the working surface, the first water outlet is always located on the upper side of the second water outlet, and the opening end of the cavity is located at a position higher than the first water outlet, thereby preventing the cleaning liquid from flowing back into the inner cavity of the liquid storage device through the first water outlet.

[0055] By providing a blocking device within the liquid storage device, when the cleaning robot moves upward or downward on the working surface, the blocking device can prevent the liquid passing through the first water outlet from flowing back into the inner cavity of the liquid storage device, so that the first water outlet is always kept full of water, isolating the atmosphere inside and outside the first water outlet, and preventing gas from entering the inner cavity of the liquid storage device from the first water outlet. This in turn makes the inward atmospheric pressure at the second water outlet higher than the outward pressure of the liquid inside the second water outlet, effectively preventing liquid from dripping from the second water outlet. When the cleaning robot moves leftward or rightward on the working surface, there is liquid at both the first water outlet and the second water outlet, isolating the atmosphere inside and outside the liquid storage device, and there is inward atmospheric pressure at the first and second water outlets, and the inward atmospheric pressure is higher than the outward pressure of the liquid inside the first and second water outlets, thereby preventing liquid from dripping from the first and second water outlets.

[0056] For ease of understanding, refer to Figures 1 to 8 , the specific structure and working principle of the cleaning robot disclosed in the present invention are explained in detail with reference to an embodiment.

[0057] like Figure 1 、 Figure 4 and Figure 5 As shown, the cleaning robot provided by the present disclosure includes a body 1 and a liquid storage device 2. The body 1 is configured to move on a work surface and is constructed to have a first motion posture in which the body 1 moves in a height direction on the work surface. The liquid storage device 2 is disposed within the body 1 and is provided with at least a first water outlet 3 and a second water outlet 4 that communicate with its inner cavity. A baffle device 5 is disposed within the liquid storage device 2 adjacent to the first water outlet 3. The baffle device 5 is constructed to form a cavity 13 that encloses the first water outlet 3 and has an open end 12. The first water outlet 3 is configured to communicate with the inner cavity of the liquid storage device 2 through the open end 12. When in the first motion posture, the first water outlet 3 is configured to be located above the second water outlet 4, and the open end 12 of the cavity 13 is configured to be located above the first water outlet 3, so as to prevent liquid from flowing back into the inner cavity of the liquid storage device 2 through the first water outlet 3.

[0058] Specifically, if Figure 1 and Figure 8As shown, the cleaning robot provided by the present disclosure includes a body 1 and a liquid storage device 2. Among them, running wheels can be provided on the side of the body 1 that contacts the work surface, and the running wheels can not only drive the cleaning robot to move parallel to the work surface, but also drive the cleaning robot to rotate on the work surface, so that the cleaning robot can move to various places on the work surface, and then clean the entire work surface. In addition, the body 1 is also provided with cleaning components in the form of rags and trays for cleaning the work surface. When the cleaning robot is a window cleaning robot, a vacuum component can also be provided on the body 1, and the vacuum component forms a negative pressure to adsorb the window cleaning robot on the window. In this embodiment, the shape of the body 1 can be set according to actual needs, and can be set to square or round, and no limitation is made here.

[0059] like Figure 6 As shown, the body 1 is also constructed to have a first movement posture of moving in the height direction on the working surface. In this movement posture, the walking wheels on the body 1 drive the cleaning robot to move upward or downward. The body 1 is adsorbed on the working surface through the vacuum component, and the cleaning component cleans along the movement path of the cleaning robot.

[0060] The liquid storage device 2 is provided in the body 1. Cleaning liquid is provided in the liquid storage device 2. When the cleaning robot is working, the cleaning liquid in the liquid storage device 2 is combined with the cleaning components to clean the working surface. In addition, a first water outlet 3 and a second water outlet 4 are provided at both ends of the liquid storage device 2. The first water outlet 3 and the second water outlet 4 are both connected to the liquid storage device 2. The cleaning liquid in the liquid storage device 2 is discharged through the first water outlet 3 and the second water outlet 4 to clean the working surface. Figure 5 As shown, a blocking device 5 is provided in the liquid storage device 2 near the first water outlet 3, and the blocking device 5 encloses the first water outlet 3 to form a cavity 13, and the cavity 13 has an open end 12, and the first water outlet 3 is connected to the inner cavity of the liquid storage device 2 through the open end 12.

[0061] like Figure 6 As shown, when the body 1 is in the first motion posture, that is, when the cleaning robot is moving upward or downward on the working surface, the first water outlet 3 is always located on the upper side of the second water outlet 4, and the open end 12 of the cavity 13 is located at a position higher than the first water outlet 3, thereby preventing the liquid passing through the first water outlet 3 from flowing back into the inner cavity of the liquid storage device 2, so that the first water outlet 3 is always kept full of water, thereby isolating the inside and outside atmosphere of the first water outlet 3, preventing gas from entering the inner cavity of the liquid storage device 2 from the first water outlet 3, and thus making the inward atmospheric pressure at the second water outlet 4 higher than the outward pressure of the liquid inside the second water outlet 4, effectively preventing the second water outlet 4 from dripping.

[0062] like Figures 2 to 4As shown, in one embodiment of the present disclosure, the cleaning robot also includes a liquid outlet device 6, which includes at least a first liquid outlet component 61 and a second liquid outlet component 62, and the first liquid outlet component 61 and the second liquid outlet component 62 are relatively arranged on both sides of the body 1; the first liquid outlet component 61 is constructed to be connected to the first water outlet 3; the second liquid outlet component 62 is constructed to be connected to the second water outlet 4; the liquid in the liquid storage device 2 is configured to flow out from the first liquid outlet component 61 and / or the second liquid outlet component 62.

[0063] Specifically, if Figure 1 and Figure 4 As shown, a first liquid outlet assembly 61 and a second liquid outlet assembly 62 are respectively provided at the edges of both sides of the machine body 1. The first liquid outlet assembly 61 and the second liquid outlet assembly 62 are configured to spray cleaning liquid onto the work surface. The first liquid outlet assembly 61 is connected to the first water outlet 3, and the second liquid outlet assembly 62 is connected to the second water outlet 4. The cleaning liquid in the liquid storage device 2 will flow out from the first liquid outlet assembly 61 and / or the second liquid outlet assembly 62. When the body 1 is in the first motion posture, as the cleaning robot moves upward along the working surface, the barrier device 5 prevents liquid from flowing back through the first water outlet 3 into the inner cavity of the liquid storage device 2, keeping the first water outlet 3 always full of water and isolating the atmosphere inside and outside the first water outlet 3. To ensure that the first water outlet 3 is always full of water, the first liquid outlet assembly 61 and the second liquid outlet assembly 62 are configured to prevent liquid from flowing, thereby preventing gas from entering the inner cavity of the liquid storage device 2 from the first water outlet 3. This, in turn, makes the atmospheric pressure inward at the second water outlet 4 higher than the outward pressure of the liquid inside the second water outlet 4, effectively preventing the second liquid outlet assembly 62 from dripping. When the cleaning robot moves downward along the working surface, the first liquid outlet assembly 61 does not flow, and the liquid in the liquid storage device 2 flows out from the second liquid outlet assembly 62, and the second liquid outlet assembly 62 discharges liquid. In this way, after the second liquid outlet assembly 62 sprays cleaning liquid onto the working surface to wet the working surface, the cleaning assembly can then clean that portion of the working surface and remove dirt on the working surface.

[0064] It is understandable that when the cleaning robot of the present invention is working in other postures, the liquid in the liquid storage device 2 will flow out from the first water outlet 3 and the second water outlet 4, and be sprayed out from the corresponding nozzles to spray the liquid on the working surface. When the cleaning robot switches from this state to the first motion posture, the liquid remaining in the first water outlet 3 or in the pipeline between the first water outlet 3 and the corresponding liquid outlet has a tendency to flow back into the liquid storage device 2. At this time, since the passage between the first water outlet 3 and the liquid storage device 2 is blocked by the above-mentioned cavity 13, the liquid will still remain in the pipeline between the first water outlet 3 and the corresponding liquid outlet, thereby blocking the gas passage between the first water outlet 3 and the inner cavity of the liquid storage device 2, so that a certain negative pressure environment can be formed in the inner cavity of the liquid storage device 2.

[0065] like Figure 4 As shown, in one embodiment of the present disclosure, the first liquid outlet component 61 includes a first liquid outlet seat 63 having a first liquid outlet hole, a first adapter seat 65 docking with the first liquid outlet seat 63, and a first atomizing piece 67 located between the first adapter seat 65 and the first liquid outlet seat 63; the first atomizing piece 67 is configured to atomize the liquid when powered on and spray it from the first liquid outlet hole; the second liquid outlet component 62 includes a second liquid outlet seat 64 having a second liquid outlet hole, a second adapter seat 66 docking with the second liquid outlet seat 64, and a second atomizing piece 68 located between the second adapter seat 66 and the second liquid outlet seat 64; the second atomizing piece 68 is configured to atomize the liquid when powered on and spray it from the second liquid outlet hole.

[0066] Specifically, the first liquid outlet assembly 61 includes a first liquid outlet seat 63 having a first liquid outlet hole, a first adapter seat 65 docking with the first liquid outlet seat 63, and a first atomizing plate 67 located between the first adapter seat 65 and the first liquid outlet seat 63. The first liquid outlet seat 63 is connected to the first water outlet 3 via the first water inlet pipe 7. The first atomizing plate 67 is disposed between the first adapter seat 65 and the first liquid outlet seat 63. The number of first atomizing plates 67 can be set according to actual needs. In this embodiment, two sets of first atomizing plates 67 are disposed in the first liquid outlet assembly 61. Each group of first atomizing sheets 67 is composed of a metal sheet and a ceramic sheet bonded together, and a number of first liquid outlet holes are provided on the metal sheet. The first atomizing sheet 67 is connected to the signal line 11. When the first atomizing sheet 67 is energized via the signal line 11, the cleaning liquid enters the first atomizing sheet 67 of the first liquid outlet assembly 61 from the first water outlet 3. The ceramic sheet in the first atomizing sheet 67 drives the metal sheet to vibrate through high-frequency vibration, thereby quickly decomposing the liquid into tiny water droplets, which are then sprayed out through the first liquid outlet hole, thereby realizing the liquid discharge function. In this embodiment, the spray axis of each group of first atomizing sheets 67 can be set to radiate outward from the outside of the body 1 and away from each other. After such a setting, the cleaning liquid sprayed by each group of first atomizing sheets 67 will not interfere with each other, thereby effectively extending the spray distance of the cleaning liquid and reducing the spray blind area. At the same time, since the spray ranges of adjacent first atomizing plates 67 partially overlap, the amount of cleaning liquid at the edge and center of the spray range tends to be consistent, ensuring the uniformity of the cleaning liquid mist coverage on the working surface, which not only improves the cleaning efficiency of the cleaning robot, but also optimizes the user experience.

[0067] The first liquid outlet assembly 61 also includes a first adapter seat 65 that docks with the first liquid outlet seat 63. The first adapter seat 65 is connected to the first water outlet 3 through the first water inlet pipe 7 and transports the cleaning liquid from the first water inlet pipe 7 to the first liquid outlet assembly 61. In addition, the shape of the first adapter seat 65 matches that of the first liquid outlet seat 63 to ensure that the two can dock tightly and accurately, which not only facilitates assembly and disassembly, but also ensures the sealing and stability of the connection, thereby improving the working efficiency and reliability of the entire liquid outlet assembly. In this embodiment, the interface portion of the first adapter seat 65 and the first liquid outlet seat 63 adopts a complementary design, such as a concave-convex fit, a snap-fit ​​structure or other form of mechanical locking mechanism to ensure that the two can be accurately aligned and firmly fixed during installation. The first atomizer plate 67 is located between the first adapter seat 65 and the first liquid outlet seat 63. When power is turned on, the cleaning liquid enters the first liquid outlet assembly 61 through the first adapter seat 65 and is converted into fine droplets by the first atomizer plate 67 and evenly sprayed out through the first liquid outlet hole. The specific structures and working principles of the second liquid outlet seat 64 , the second adapter seat 66 and the second atomizing plate 68 may refer to the first liquid outlet seat 63 , the first adapter seat 65 and the first atomizing plate 67 , and are not described in detail here.

[0068] In the embodiment of the present disclosure, since the liquid is atomized and then sprayed out by vibrating the atomizing plate, the liquid outlet holes of the two liquid outlet components are always in a state of being able to communicate with the inner cavity of the liquid storage device 2. The liquid in the liquid storage device 2 has a tendency to flow toward the corresponding liquid outlet hole under the action of its own gravity or in a natural state, and the atomized liquid is sprayed out under the vibration of the atomizing plate. At this time, if the cleaning robot switches from other postures to the first motion posture, the liquid from the first liquid outlet component 61 to the first water outlet 3 located above will flow back into the inner cavity of the liquid storage device 2, so that the liquid storage device 2 is connected to the outside atmosphere through the first liquid outlet hole of the first liquid outlet component 61. Then, the liquid will flow out from the second liquid outlet hole of the second liquid outlet component 62 under the action of gravity, causing dripping or leakage problems.

[0069] like Figures 2 to 6 As shown, in one embodiment of the present disclosure, when in the first motion posture, the first water outlet 3 and the second water outlet 4 are constructed to be located on the upper and lower sides of the body 1 respectively, and the liquid in the inner cavity of the liquid storage device 2 is configured to have a tendency to flow toward the second water outlet 4.

[0070] Specifically, when the body 1 is in the first motion posture, the cleaning robot moves in an upward or downward direction on the working surface. At this time, the first water outlet 3 and the second water outlet 4 are respectively located on the upper and lower sides of the body 1. Under the action of gravity, the cleaning liquid in the inner cavity of the liquid storage device 2 is configured to flow to the second water outlet 4. Since the blocking device 5 is provided in the liquid storage device 2, the liquid in the first water outlet 3 cannot flow back into the inner cavity of the liquid storage device 2, so that air cannot enter the first water outlet 3. In addition, it can ensure that the inward air pressure at the second water outlet 4 is greater than the outward pressure of the liquid in the second water outlet 4, thereby preventing the second water outlet 4 from dripping.

[0071] like Figure 7 As shown, in one embodiment of the present disclosure, the body 1 is configured to switch between a first motion posture and a second motion posture; when in the second motion posture, the first water outlet 3 and the second water outlet 4 are located on both sides of the liquid storage device 2 in the horizontal direction.

[0072] Specifically, the body 1 also has a second motion posture of moving in the horizontal direction on the working surface, that is, the cleaning robot can move in the left or right direction on the working surface. When the body 1 is in the second motion posture, the first water outlet 3 and the second water outlet 4 are both located on both sides of the liquid storage device 2 in the horizontal direction, and the first liquid outlet component 61 and the second liquid outlet component 62 are respectively located on both sides of the body 1 in the horizontal direction. In this way, when the cleaning robot moves to the left or right in the horizontal direction, there is cleaning liquid in the first liquid outlet component 61 and the second liquid outlet component 62, so that the air inside and outside the liquid storage device 2 is isolated, and there is an inward atmospheric pressure at the aperture of the first liquid outlet hole and the second liquid outlet hole. The atmospheric pressure is higher than the outward pressure of the liquid inside the first liquid outlet hole and the second liquid outlet hole, which can effectively prevent the first liquid outlet component 61 and the second liquid outlet component 62 from dripping.

[0073] In one embodiment of the present disclosure, when the body 1 switches from the second motion posture to the first motion posture, the blocking device 5 is configured to prevent the liquid from flowing back into the inner cavity of the liquid storage device 2 through the first water outlet 3 .

[0074] Specifically, when the cleaning robot disclosed in the present invention switches from the second motion posture to the first motion posture, the liquid in the liquid storage device 2 will flow out from the first water outlet 3 and the second water outlet 4, and the liquid remaining in the first water outlet 3 or in the pipeline between the first water outlet 3 and the corresponding liquid outlet hole has a tendency to flow back into the liquid storage device 2. At this time, the liquid storage device 2 contains a small amount of cleaning liquid. Since the passage between the first water outlet 3 and the liquid storage device 2 is blocked by the above-mentioned cavity 13, a small amount of cleaning liquid will still remain in the pipeline between the first water outlet 3 and the corresponding liquid outlet hole, thereby blocking the gas passage between the first water outlet 3 and the inner cavity of the liquid storage device 2, so that a certain negative pressure environment can be formed in the inner cavity of the liquid storage device 2, which can still play a good liquid sealing role to prevent dripping.

[0075] like Figure 7 As shown, in one embodiment of the present disclosure, when in the second motion posture, the liquid storage device 2 is constructed to be located above the first water outlet 3 and the second water outlet 4, and the liquid in the liquid storage device 2 is configured to have a tendency to flow toward the first water outlet 3 and the second water outlet 4 under the action of its own gravity.

[0076] Specifically, when the body 1 is in the second motion posture, the liquid storage device 2 is located above the first water outlet 3 and the second water outlet 4. During operation, the cleaning robot moves horizontally to the left or right, and the cleaning liquid in the liquid storage device 2 flows to the first liquid outlet assembly 61 and the second liquid outlet assembly 62 respectively under the action of gravity, allowing the cleaning robot to discharge liquid smoothly during operation and ensuring the continuity of the cleaning process.

[0077] like Figure 5 and Figure 7 As shown, in one embodiment of the present disclosure, when in the second motion posture, the open end 12 of the cavity 13 is constructed to face horizontally away from the first water outlet 3; the liquid in the inner cavity of the liquid storage device 2 is configured to flow toward the second water outlet 4, and to flow toward the first water outlet 3 through the open end 12.

[0078] Specifically, when the robot body 1 is in the second motion posture, the open end 12 of the cavity 13 is horizontally oriented toward the outside of the liquid storage device 2, i.e., the open end 12 is located on the left side of the entire cavity 13. When the cleaning robot moves horizontally, the cleaning liquid in the inner cavity of the liquid storage device 2 flows through the open end 12 to the first water outlet 3 under the action of gravity, and enters the first liquid outlet assembly 61, and flows through the open end 12 to the first water outlet 3. When the cleaning robot moves to the left, the first liquid outlet assembly 61 sprays cleaning liquid onto the working surface, and the cleaning assembly cleans that portion of the working surface.

[0079] like Figure 6As shown, in one embodiment of the present disclosure, the cleaning robot also includes a control unit. In the first motion posture, the control unit is configured to control only the second liquid outlet component 62 to be powered on during the downward movement of the cleaning robot to discharge liquid to the working surface below the cleaning robot; and to control the first liquid outlet component 61 and the second liquid outlet component 62 to be powered off during the upward movement of the cleaning robot.

[0080] Specifically, the cleaning robot is also provided with a control unit, which is used to control the power on and off of the first liquid outlet component 61 and the second liquid outlet component 62. When the body 1 is in the first motion posture, the cleaning robot moves upward or downward. During the downward movement of the cleaning robot, the control unit controls the power on of the second liquid outlet component 62 and puts the first liquid outlet component 61 in a power-off state. At this time, the second liquid outlet component 62 can discharge liquid to the working surface below the cleaning robot. During the upward movement of the cleaning robot, the control unit controls the power off of the first liquid outlet component 61 and the second liquid outlet component 62. Neither the first liquid outlet component 61 nor the second liquid outlet component 62 discharges liquid, thereby preventing gas from entering the inner cavity of the liquid storage device 2 from the first liquid outlet component 61, and thereby making the atmospheric pressure inward at the second liquid outlet component 62 higher than the outward pressure of the liquid inside the second liquid outlet component 62, effectively preventing the second liquid outlet component 62 from dripping.

[0081] In combination with the above-mentioned embodiments in which each liquid outlet component adopts atomization vibration to discharge liquid, if the atomizing plate is controlled to be energized, the atomizing plate will vibrate to atomize the liquid and then spray it out from the corresponding liquid outlet hole; if the atomizing plate is controlled to be in a power-off state, the liquid will remain in the affected pipeline and will not spray out from the corresponding liquid outlet hole.

[0082] like Figure 7 As shown, in one embodiment of the present disclosure, the cleaning robot further includes a control unit. In the second motion posture, the control unit is configured to control the first liquid outlet component 61 to be energized when the cleaning robot moves toward the side where the first liquid outlet component 61 is located; and to control the second liquid outlet component 62 to be energized when the cleaning robot moves toward the side where the second liquid outlet component 62 is located.

[0083] Specifically, when the body 1 is in the second motion posture, the control unit can control the power on and off of the first liquid outlet component 61 and the second liquid outlet component 62 according to the direction of travel of the cleaning robot. For example, the first liquid outlet component 61 is set on the left side of the body 1. When the cleaning robot moves to the left, the control unit controls the power on of the first liquid outlet component 61. The first liquid outlet component 61 discharges liquid to the working surface on the left side of the cleaning robot, and the cleaning component cleans the working surface after the liquid is discharged. The second liquid outlet component 62 is set on the right side of the body 1. When the cleaning robot moves to the right, the control unit controls the power on of the second liquid outlet component 62. The second liquid outlet component 62 discharges liquid to the working surface on the right side of the cleaning robot, and the cleaning component cleans the working surface after the liquid is discharged.

[0084] The cleaning robot disclosed herein can operate on, for example, a glass surface in a first motion posture, such as moving up or down on the glass surface and cleaning the glass surface during the motion; or it can operate on the glass surface in a second motion posture, such as moving left or right on the glass surface and cleaning the glass surface during the motion. When the cleaning robot is working in the second motion posture, the two liquid outlet components are located on the left and right sides of the cleaning robot. When the cleaning robot moves to the left, the liquid outlet component on the left is controlled to discharge liquid to the working surface on the left side of the cleaning robot; when the cleaning robot moves to the right, the liquid outlet component on the right is controlled to discharge liquid to the working surface on the right side of the cleaning robot. When the cleaning robot walks to a predetermined position on the glass surface or controls the cleaning robot to turn according to the corresponding control logic, thereby switching to the first motion posture, the first water outlet 3 is located on the upper side of the cleaning robot, and the second water outlet 4 is located on the lower side of the cleaning robot. The cavity 13 can then block the first liquid outlet component 61 from flowing back into the liquid storage device 2 to the liquid outlet component 3, thereby preventing the liquid from leaking from the second liquid outlet component 62 located below.

[0085] like Figures 2 to 5 As shown, in one embodiment of the present disclosure, the first water outlet 3 is arranged on the side wall of the liquid storage device 2, and the blocking device 5 includes a semi-enclosed enclosing side wall 51, a bottom wall and a top wall. The side wall of the liquid storage device 2 and the enclosing side wall 51, the bottom wall and the top wall form a cavity 13; the semi-enclosed enclosing side wall 51 forms an open end 12 between its free end and the side wall of the liquid storage device 2.

[0086] Specifically, the first water outlet 3 is provided on the side wall of the liquid storage device 2 and is in communication with the inner cavity of the liquid storage device 2. The baffle device 5 is provided at a position adjacent to the liquid storage device 2. The baffle device 5 comprises a semi-enclosed enclosing side wall 51, a bottom wall and a top wall. The side wall of the liquid storage device 2 and the enclosed side wall 51, the bottom wall and the top wall of the baffle device 5 together form a cavity 13. An open end 12 is formed between the free end of the enclosed side wall 51 and the side wall of the liquid storage device 2. Figure 6 As shown, when the machine body 1 is in the first posture, the liquid in the first water outlet 3 can only flow back into the cavity 13, and cannot flow back from the open end 12 of the cavity 13 to the inner cavity of the liquid storage device 2, so that the first water outlet 3 is always kept full of water, and the inner and outer atmospheres of the first water outlet 3 are isolated to prevent gas from entering the inner cavity of the liquid storage device 2 from the first water outlet 3, thereby making the inward atmospheric pressure at the second water outlet 4 higher than the outward pressure of the liquid inside the second water outlet 4, effectively preventing the second water outlet 4 from dripping.

[0087] like Figures 2 to 3 As shown, in one embodiment of the present disclosure, the liquid storage device 2 includes an upper shell 23 and a lower shell 24; after the upper shell 23 and the lower shell 24 are buckled together, the upper shell 23, the blocking device 5, and the lower shell 24 are constructed to be enclosed together to form a cavity 13.

[0088] Specifically, the liquid storage device 2 is composed of an upper shell 23 and a lower shell 24 that are interlocked. The baffle device 5 can be configured so that a portion is located inside the upper shell 23 and the other portion is located inside the lower shell 24, which helps to ensure the stability and sealing of the internal structure of the liquid storage device 2. At the same time, by rationally allocating the position of the baffle device 5, the flow and distribution of the cleaning liquid can be effectively managed and controlled, thereby improving the overall performance of the liquid storage device 2. For example, the upper shell 23 and the lower shell 24 can be connected by ultrasonic welding, and the baffle device 5 located in the upper shell 23 and the lower shell 24 are constructed to be enclosed together to form a sealed cavity 13, thereby blocking the gas passage between the first water outlet 3 and the inner cavity of the liquid storage device 2. In another embodiment of the present disclosure, the baffle device 5 can also be configured as a separate integrally molded structure, and a sealing assembly is provided in the portion enclosed by the baffle device 5 and the upper shell 23 and the lower shell 24, thereby improving the sealing of the liquid storage device 5.

[0089] like Figures 2 to 7 As shown, in one embodiment of the present disclosure, the liquid storage device 2 includes a main box body 21, which is constructed to be arranged on one side of the body 1; when in the first motion posture, the open end 12 is located on the upper side of the main box body 21 and is constructed to face the upper side of the main box body 21.

[0090] Specifically, the liquid storage device 2 includes a main housing 21 and an extension housing 22, which are interconnected. When the housing 1 is in the first motion posture, the main housing 21 is disposed on one side of the housing 1. A first liquid outlet assembly 61 is disposed on this side corresponding to the main housing 21. The first liquid outlet assembly 61 is connected to the first water outlet 3 via a first water inlet pipe 7. A liquid injection hole 9 and a liquid injection plug 10 are also disposed on the main housing 21. The liquid injection hole 9 is configured for injecting cleaning liquid into the main housing 21. The liquid injection plug 10 is configured to cooperate with the liquid injection hole 9 to ensure that the liquid injection hole 9 is sealed when liquid is not being injected, preventing leakage of cleaning liquid or entry of external impurities. The extension housing 22 extends from the main housing 21 to the other side of the housing 1. A second liquid outlet assembly 62 is disposed on the side of the housing 1 opposite the first liquid outlet assembly 61 and is connected to the second water outlet 4 on the extension housing 22 via a second water inlet pipe 8.

[0091] In one embodiment of the present disclosure, the connection between the extension box body 22 and the main box body 21 is set to an arc structure, so that there is a certain height between the extension box body 22 and the main box body 21. Under the action of gravity, the cleaning liquid tends to flow from the main box body 21 to the extension box body 22, which is conducive to the collection of the cleaning liquid to the extension box body 22.

[0092] When in the first motion position, the main housing 21 is located on the upper side of the machine body 1, and the open end 12 is located on the upper side of the main housing 21 and faces the upper side of the main housing 21. Under the action of gravity, the cleaning liquid in the main housing 21 flows toward the extension housing 22, and flows out of the second water outlet 4 of the extension housing 22, through the second water inlet pipe 8, and into the second liquid outlet assembly. The second liquid outlet assembly then discharges the liquid toward the working surface below the machine body 1, where the cleaning assembly cleans this portion of the working surface. In this movement posture, the first water outlet 3 has a tendency to flow back, but because the open end 12 is facing the upper side of the main box body 21, and the top of the open end 12 is higher than the top of the first water outlet 3, the liquid in the first water outlet 3 cannot flow out of the open end 12 and flow into the inner cavity of the main box body 21, isolating the inside and outside atmosphere of the first water outlet 3, preventing gas from entering the inner cavity of the liquid storage device 2 from the first water outlet 3, and thus making the inward atmospheric pressure at the second water outlet 4 higher than the outward pressure of the liquid inside the second water outlet 4, effectively preventing the second water outlet 4 from dripping.

[0093] like Figures 2 to 3 As shown, in one embodiment of the present disclosure, the position of the main box body 21 adjacent to the first water outlet 3 is constructed to extend outward to form an extension chamber 212 connected to the main box body chamber 211, the blocking device 5 is constructed to extend from the position of the main box body chamber 211 to the extension chamber 212, and the opening end 12 is constructed to be located in the extension chamber 212.

[0094] Specifically, the main housing 21 includes a main housing chamber 211 and an extension chamber 212. The extension chamber 212 is located in the main housing 21 adjacent to the first water outlet 3. The extension chamber 212 extends outward relative to the main housing 21. The blocking device 5 extends from the main housing chamber 211 to the extension chamber 212, and the open end 12 is located in the extension chamber 212. In this way, when the machine body 1 is in the first motion posture, the extension chamber 212 is located at the upper end of the main housing chamber 211. The liquid in the main housing chamber 211 has a tendency to flow downward. At this time, there is air in the extension chamber 212. Therefore, on the basis of the cavity 13 preventing the liquid from flowing back from the first water outlet 3 to the liquid storage device, the negative pressure environment in the inner cavity 13 of the liquid storage device can be further increased, thereby preventing the second liquid outlet assembly 62 from dripping.

[0095] like Figure 1 、 Figures 5 to 7 As shown, in another embodiment of the present disclosure, the cleaning robot includes a body 1 and a liquid storage device 2, the body 1 is configured to move on a working surface, and the body 1 is constructed to have a first motion posture of moving in a height direction on the working surface, and a second motion posture of moving in a horizontal direction; the liquid storage device 2 is arranged in the body 1, and at least a first water outlet 3 and a second water outlet 4 connected to its inner cavity are provided on the liquid storage device 2; a blocking device 5 is provided at a position adjacent to the first water outlet 3 in the liquid storage device 2; when the body 1 switches from the second motion posture to the first motion posture, the blocking device 5 is constructed to prevent the liquid from flowing back into the inner cavity of the liquid storage device 2 through the first water outlet 3.

[0096] Specifically, the cleaning robot provided by the present disclosure includes a body 1 and a liquid storage device 2. The body 1 has two motion postures on the working surface: a first motion posture in which the body 1 moves in a height direction on the working surface, and a second motion posture in which the body 1 moves in a horizontal direction. A first water outlet 3 and a second water outlet 4 are also provided at both ends of the liquid storage device 2. The first water outlet 3 and the second water outlet 4 are both connected to the liquid storage device 2. Cleaning liquid in the liquid storage device 2 is discharged through the first water outlet 3 and the second water outlet 4 to clean the working surface. When the body 1 switches from the second motion posture to the first motion posture, because the opening end 12 of the cavity 13 formed by the baffle device 5 is higher than the height of the first water outlet 3, the baffle device 5 can isolate the atmosphere inside and outside the first water outlet 3, preventing gas from entering the inner cavity of the liquid storage device 2 through the first water outlet 3. This, in turn, makes the atmospheric pressure inward at the second water outlet 4 higher than the outward pressure of the liquid inside the second water outlet 4, effectively preventing dripping from the second water outlet 4.

[0097] like Figure 5As shown, in another embodiment of the present disclosure, the blocking device 5 is constructed to form a cavity 13 enclosing the first water outlet 3 and having an open end 12; the first water outlet 3 is constructed to communicate with the inner cavity of the liquid storage device 2 through the open end 12.

[0098] Specifically, a blocking device 5 is provided in the liquid storage device 2 near the first water outlet 3, and the blocking device 5 encloses the first water outlet 3 to form a cavity 13, and the cavity 13 has an open end 12, and the first water outlet 3 is connected to the inner cavity of the liquid storage device 2 through the open end 12.

[0099] like Figure 6 As shown, in another embodiment of the present disclosure, when in the first motion posture, the first water outlet 3 is constructed to be located on the upper side of the second water outlet 4, and the open end 12 of the cavity 13 is constructed to be located at a position higher than the first water outlet 3 to prevent the liquid from flowing back into the inner cavity of the liquid storage device 2 through the first water outlet 3.

[0100] like Figure 6 As shown, when the body 1 is in the first motion posture, that is, when the cleaning robot moves upward or downward on the working surface, the first water outlet 3 is always located on the upper side of the second water outlet 4, and the open end 12 of the cavity 13 is located at a position higher than the first water outlet 3, thereby preventing the liquid from flowing back into the inner cavity of the liquid storage device 2 through the first water outlet 3, so that the first water outlet 3 is always kept full of water, thereby isolating the inside and outside atmosphere of the first water outlet 3, preventing gas from entering the inner cavity of the liquid storage device 2 from the first water outlet 3, and thus making the inward atmospheric pressure at the second water outlet 4 higher than the outward pressure of the liquid inside the second water outlet 4, effectively preventing the second water outlet 4 from dripping.

[0101] The cleaning robot provided by the present disclosure has a baffle device disposed within the liquid storage device. When the cleaning robot moves upward or downward on a working surface, the baffle device can prevent the liquid passing through the first water outlet from flowing back into the inner cavity of the liquid storage device, thereby keeping the first water outlet always full of water. The first water outlet is isolated from the atmosphere inside and outside the first water outlet, preventing gas from entering the inner cavity of the liquid storage device from the first water outlet. This in turn makes the inward atmospheric pressure at the second water outlet higher than the outward pressure of the liquid inside the second water outlet, effectively preventing liquid from dripping from the second water outlet. When the cleaning robot moves leftward or rightward on the working surface, liquid is present at both the first water outlet and the second water outlet, isolating the atmosphere inside and outside the liquid storage device. The inward atmospheric pressure at the first and second water outlets is higher than the outward pressure of the liquid inside the first and second water outlets, thereby preventing liquid from dripping from the first and second water outlets.

[0102] It should be noted that for the aforementioned method embodiments, for ease of description, they are all expressed as a series of action combinations, but those skilled in the art should be aware that the present disclosure is not limited by the order of the actions described, because according to the present disclosure, certain steps can be performed in other orders or simultaneously.
