Description

Technical Field

[0001] This disclosure relates to the field of smart home technology, and more specifically, to a cleaning robot. Background Technology

[0002] Window cleaning robots are intelligent cleaning devices designed for automatic window cleaning. They are suitable for various scenarios, including homes, offices, and commercial buildings, offering significant convenience and safety, especially for windows in high-rise buildings or those that are difficult to reach. To achieve high levels of cleanliness, most window cleaning robots have left and right water spraying functions. However, because existing spray structures have water jets at both ends, water can seep out of these jets due to gravity when the machine operates in certain postures, causing dripping and ultimately affecting the cleaning effect and user experience.

Detailed Implementation

[0027] 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, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0028] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0031] The specific embodiments of this disclosure are described below with reference to the accompanying drawings.

[0032] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0033] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0034] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0035] This disclosure provides a cleaning robot applicable to home or commercial settings. The cleaning robot can be a window-cleaning robot for cleaning windows or glass exterior walls. The cleaning robot includes a body and a liquid storage device. The body is configured to move on a working surface and has a first motion posture moving vertically on the working surface and a second motion posture moving horizontally on the working surface. The first motion posture is for the cleaning robot to move upwards or downwards on the working surface, and the second motion posture is for the cleaning robot to move leftwards or rightwards on the working surface.

[0036] A liquid storage device is located inside the machine body, containing cleaning fluid. During robot operation, the cleaning surface is cleaned using this fluid. Furthermore, the liquid storage device has a first outlet and a second outlet, both connected to the storage device. The cleaning fluid is output through these outlets to clean the work surface. A baffle device is positioned near the first outlet within the storage device, enclosing it to form a cavity with an open end. The first outlet communicates with the inner cavity of the storage device through this open end.

[0037] When the robot is in the first motion posture, that is, during the upward or downward movement of the cleaning robot on the working surface, the first water outlet is always located above the second water outlet, and the opening end of the cavity is located above the first water outlet, thereby preventing the cleaning liquid from flowing back into the inner cavity of the storage device through the first water outlet.

[0038] By installing a baffle device inside the liquid storage device, when the cleaning robot moves upward or downward on the working surface, the baffle device can prevent the liquid passing through the first outlet from flowing back into the inner cavity of the liquid storage device, keeping the first outlet always full of water. This isolates the first outlet from the atmosphere, preventing gas from entering the inner cavity of the liquid storage device from the first outlet. Consequently, the inward atmospheric pressure at the second outlet is higher than the outward pressure of the liquid inside the second outlet, effectively preventing dripping from the second outlet. When the cleaning robot moves left or right on the working surface, there is liquid at both the first and second outlets, further isolating the liquid storage device from the atmosphere. There is inward atmospheric pressure at both the first and second outlets, and this inward atmospheric pressure is higher than the outward pressure of the liquid inside the first and second outlets, thus preventing dripping from the first and second outlets.

[0039] For ease of understanding, please refer to the following: Figures 1 to 8 The specific structure and working principle of the cleaning robot disclosed herein will be described in detail with reference to one embodiment.

[0040] like Figure 1 , Figure 4 and Figure 5 As shown, the cleaning robot provided in this disclosure includes a body 1 and a liquid storage device 2. The body 1 is configured to move on a working surface and is constructed to have a first motion posture where it moves along the height direction on the working surface. The liquid storage device 2 is disposed within the body 1 and has at least a first outlet 3 and a second outlet 4 communicating with its internal cavity. A baffle device 5 is disposed within the liquid storage device 2 adjacent to the first outlet 3, and the baffle device 5 is constructed to form a cavity 13 enclosing the first outlet 3 and having an open end 12. The first outlet 3 is constructed to communicate with the internal cavity of the liquid storage device 2 through the open end 12. In the first motion posture, the first outlet 3 is constructed to be located above the second outlet 4, and the open end 12 of the cavity 13 is constructed to be located above the first outlet 3, to prevent liquid from flowing back into the internal cavity of the liquid storage device 2 through the first outlet 3.

[0041] Specifically, such as Figure 1 and Figure 8As shown, the cleaning robot provided in this disclosure includes a body 1 and a liquid storage device 2. A walking wheel can be provided on the side of the body 1 that contacts the working surface. The walking wheel can not only drive the cleaning robot to move parallel to the working surface, but also drive it to rotate on the working surface, thereby enabling the cleaning robot to move to various parts of the working surface and clean the entire surface. In addition, the body 1 is also provided with cleaning components such as a wiping cloth tray for cleaning the working surface. When the cleaning robot is a window cleaning robot, a vacuum component can also be provided on the body 1. The vacuum component creates negative pressure to adhere the window cleaning robot to the window. In this embodiment, the shape of the body 1 can be set according to actual needs, and can be square or circular; no limitation is made here.

[0042] like Figure 6 As shown, the body 1 is also configured to have a first motion posture that moves along the height direction on the working surface. In this motion posture, the walking wheels on the body 1 drive the cleaning robot to move upward or downward. The body 1 is adsorbed onto the working surface by the vacuum component, and the cleaning component cleans along the movement path of the cleaning robot.

[0043] A liquid storage device 2 is installed inside the body 1. The liquid storage device 2 contains cleaning fluid. When the cleaning robot is working, the cleaning fluid in the liquid storage device 2, in conjunction with the cleaning components, cleans the working surface. Furthermore, a first water outlet 3 and a second water outlet 4 are provided at both ends of the liquid storage device 2. Both the first water outlet 3 and the second water outlet 4 are connected to the liquid storage device 2, and the cleaning fluid in the liquid storage device 2 is output through the first water outlet 3 and the second water outlet 4 to clean the working surface. Figure 5 As shown, a baffle device 5 is provided in the liquid storage device 2 near the first outlet 3. The baffle device 5 surrounds the first outlet 3 to form a cavity 13, and the cavity 13 has an open end 12. The first outlet 3 is connected to the inner cavity of the liquid storage device 2 through the open end 12.

[0044] like Figure 6 As shown, when the body 1 is in the first motion posture, that is, during the upward or downward movement of the cleaning robot on the working surface, the first water outlet 3 is always located above the second water outlet 4, and the opening end 12 of the cavity 13 is located higher than the first water outlet 3, thereby preventing the liquid through the first water outlet 3 from flowing back into the inner cavity of the liquid storage device 2, keeping the first water outlet 3 full of water, thus isolating the inner and outer 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 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.

[0045] like Figures 2 to 4As shown, in one embodiment of this disclosure, the cleaning robot further includes a liquid dispensing device 6, which includes at least a first liquid dispensing component 61 and a second liquid dispensing component 62. The first liquid dispensing component 61 and the second liquid dispensing component 62 are disposed opposite to each other on both sides of the body 1. The first liquid dispensing component 61 is configured to communicate with a first water outlet 3. The second liquid dispensing component 62 is configured to communicate with a second water outlet 4. The liquid in the liquid storage device 2 is configured to flow out from the first liquid dispensing component 61 and / or the second liquid dispensing component 62.

[0046] Specifically, such as 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 working 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 robot body 1 is in the first motion posture, as the cleaning robot moves upward along the working surface, the baffle device 5 prevents liquid from flowing back into the inner cavity of the liquid storage device 2 through the first outlet 3, keeping the first outlet 3 always full of water. This isolates the first outlet 3 from the atmosphere. To ensure the first outlet 3 remains full, the first liquid outlet assembly 61 and the second liquid outlet assembly 62 are set to not dispense liquid, thus preventing gas from entering the inner cavity of the liquid storage device 2 from the first outlet 3. Consequently, the atmospheric pressure at the second outlet 4 is higher than the pressure of the liquid inside the second 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 dispense liquid, and the liquid in the liquid storage device 2 flows out from the second liquid outlet assembly 62. Thus, after the second liquid outlet assembly 62 sprays cleaning liquid onto the working surface to wet it, the cleaning assembly can clean that part of the working surface, removing dirt.

[0047] It is understood that when the cleaning robot of this disclosure is working in other postures, the liquid in the liquid storage device 2 will flow out from the first outlet 3 and the second outlet 4, and be sprayed out from the corresponding nozzles to spray the liquid onto the working surface. When the cleaning robot switches from this state to the first motion posture, the liquid remaining in the first outlet 3 or in the pipeline between the first outlet 3 and the corresponding outlet hole tends to flow back into the liquid storage device 2. At this time, since the passage between the first outlet 3 and the liquid storage device 2 is blocked by the cavity 13, the liquid will still remain in the pipeline between the first outlet 3 and the corresponding outlet hole, thereby blocking the gas passage between the first outlet 3 and the inner cavity of the liquid storage device 2, thus creating a certain negative pressure environment in the inner cavity of the liquid storage device 2.

[0048] like Figure 4 As shown, in one embodiment of this disclosure, the first liquid dispensing assembly 61 includes a first liquid dispensing seat 63 having a first liquid dispensing hole, a first adapter seat 65 docking with the first liquid dispensing seat 63, and a first atomizing plate 67 located between the first adapter seat 65 and the first liquid dispensing seat 63; the first atomizing plate 67 is configured to atomize liquid in an energized state and spray it out from the first liquid dispensing hole; the second liquid dispensing assembly 62 includes a second liquid dispensing seat 64 having a second liquid dispensing hole, a second adapter seat 66 docking with the second liquid dispensing seat 64, and a second atomizing plate 68 located between the second adapter seat 66 and the second liquid dispensing seat 64; the second atomizing plate 68 is configured to atomize liquid in an energized state and spray it out from the second liquid dispensing hole.

[0049] Specifically, the first liquid outlet assembly 61 includes a first liquid outlet seat 63 with a first liquid outlet hole, a first adapter seat 65 that docks 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 through a 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 set of first atomizing plates 67 is composed of metal and ceramic plates bonded together. Several first liquid outlet holes are provided on the metal plates. A signal line 11 is connected to each first atomizing plate 67. When the first atomizing plate 67 is energized via the signal line 11, cleaning fluid enters the first atomizing plate 67 of the first liquid outlet assembly 61 from the first outlet 3. The ceramic plates in the first atomizing plate 67 vibrate at high frequency, causing the metal plates to vibrate, thereby rapidly decomposing the liquid into fine water droplets, which are then sprayed out through the first liquid outlet holes, thus achieving the liquid outlet function. In this embodiment, the spray axis of each set of first atomizing plates 67 can be set to radiate outwards from the outside of the body 1 and be far apart from each other. With this setting, the cleaning fluid sprayed from each set of first atomizing plates 67 will not interfere with each other, thereby effectively extending the spray distance of the cleaning fluid and reducing the spray blind zone. Meanwhile, 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. This not only improves the cleaning efficiency of the cleaning robot but also optimizes the user experience.

[0050] The first liquid dispensing assembly 61 also includes a first adapter 65 that mates with the first liquid dispensing seat 63. The first adapter 65 is connected to the first water outlet 3 via the first water inlet pipe 7, and the cleaning fluid is transported from the first water inlet pipe 7 into the first liquid dispensing assembly 61. Furthermore, the shapes of the first adapter 65 and the first liquid dispensing seat 63 are matched to ensure a tight and accurate connection, facilitating assembly and disassembly, and ensuring the sealing and stability of the connection, thereby improving the overall efficiency and reliability of the liquid dispensing assembly. In this embodiment, the interface between the first adapter 65 and the first liquid dispensing seat 63 adopts a complementary design, such as a concave-convex fit, a snap-fit ​​structure, or other forms of mechanical locking mechanism, to ensure precise alignment and secure fixation during installation. The first atomizing plate 67 is located between the first adapter 65 and the first liquid dispensing seat 63. When energized, the cleaning fluid enters the first liquid dispensing assembly 61 through the first adapter 65, and is converted into fine droplets by the first atomizing plate 67, which then sprays it out evenly through the first liquid dispensing hole. The specific structure and working principle of the second liquid outlet seat 64, the second adapter seat 66, and the second atomizing plate 68 can be found in the first liquid outlet seat 63, the first adapter seat 65, and the first atomizing plate 67, and will not be elaborated here.

[0051] In the embodiments disclosed herein, since the liquid is atomized and sprayed out by means of vibration of the atomizing plate, the outlet holes of the two liquid outlet components are always in a state where they can communicate with the inner cavity of the liquid storage device 2. The liquid in the liquid storage device 2 tends to flow towards the corresponding outlet hole under its own gravity or in a natural state, and is sprayed out by the vibration of the atomizing plate. At this time, if the cleaning robot switches from other postures to the first motion posture, the liquid in the first liquid outlet component 61 to the first 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 in a state of communication with the outside atmosphere through the first outlet hole of the first liquid outlet component 61. Then, under the action of gravity, the liquid will flow out from the second outlet hole of the second liquid outlet component 62, causing dripping or leakage problems.

[0052] like Figures 2 to 6 As shown, in one embodiment of this disclosure, when in the first motion posture, the first water outlet 3 and the second water outlet 4 are configured 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 towards the second water outlet 4.

[0053] Specifically, when the robot body 1 is in the first motion posture, the cleaning robot moves upward or downward on the working surface. At this time, the first water outlet 3 and the second water outlet 4 are located on the upper and lower sides of the robot body 1, respectively. Under the action of gravity, the cleaning fluid in the inner cavity of the liquid storage device 2 is directed to flow to the second water outlet 4. Since the liquid storage device 2 is equipped with a baffle device 5, the liquid in the first water outlet 3 cannot flow back into the inner cavity of the liquid storage device 2, preventing air from entering the first water outlet 3. This ensures 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.

[0054] like Figure 7 As shown, in one embodiment of this 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.

[0055] Specifically, the robot body 1 also has a second motion posture that allows it to move horizontally on the working surface, meaning the cleaning robot can move to the left or right on the working surface. When the robot body 1 is 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, and the first liquid outlet assembly 61 and the second liquid outlet assembly 62 are located on both sides of the robot body 1 in the horizontal direction. In this way, when the cleaning robot moves to the left or right in the horizontal direction, both the first liquid outlet assembly 61 and the second liquid outlet assembly 62 contain cleaning fluid, which isolates the air inside and outside the liquid storage device 2. There is an inward atmospheric pressure at the aperture of the first and second liquid outlet holes. The atmospheric pressure is higher than the outward pressure of the liquid inside the first and second liquid outlet holes, which can effectively prevent the first liquid outlet assembly 61 and the second liquid outlet assembly 62 from dripping.

[0056] In one embodiment of this disclosure, when the body 1 switches from a second motion posture to a first motion posture, the baffle device 5 is configured to prevent liquid from flowing back into the inner cavity of the liquid storage device 2 through the first outlet 3.

[0057] Specifically, when the cleaning robot of this disclosure 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 outlet 3 and the second outlet 4. The liquid remaining in the first outlet 3 or in the pipeline between the first outlet 3 and the corresponding outlet hole tends 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 outlet 3 and the liquid storage device 2 is blocked by the cavity 13, a small amount of cleaning liquid will still remain in the pipeline between the first outlet 3 and the corresponding outlet hole, thereby blocking the gas passage between the first outlet 3 and the inner cavity of the liquid storage device 2. This can create a certain negative pressure environment in the inner cavity of the liquid storage device 2, which can still play a good liquid sealing role and prevent dripping.

[0058] like Figure 7 As shown, in one embodiment of this disclosure, when in the second motion posture, the liquid storage device 2 is configured to be located above the first outlet 3 and the second outlet 4, and the liquid in the liquid storage device 2 is configured to have a tendency to flow towards the first outlet 3 and the second outlet 4 under its own gravity.

[0059] Specifically, when the robot 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 to the left or right in the horizontal direction, and the cleaning liquid in the liquid storage device 2 flows to the first liquid outlet component 61 and the second liquid outlet component 62 under the action of gravity, which allows the cleaning robot to smoothly dispense liquid during operation and ensures the continuity of the cleaning process.

[0060] like Figure 5 and Figure 7 As shown, in one embodiment of this disclosure, when in the second motion posture, the opening end 12 of the cavity 13 is configured to face away from the first outlet 3 in the horizontal direction; the liquid in the inner cavity of the liquid storage device 2 is configured to flow to the second outlet 4 and to the first outlet 3 through the opening end 12.

[0061] Specifically, when the robot body 1 is in the second motion posture, the opening end 12 of the cavity 13 faces the outside of the liquid storage device 2 in the horizontal direction, that is, the opening end 12 is located on the left side of the entire cavity 13. When the cleaning robot moves in the horizontal direction, the cleaning fluid in the cavity of the liquid storage device 2 flows through the opening end 12 to the first outlet 3 under the action of gravity, and enters the first liquid outlet assembly 61, and flows through the opening end 12 to the first outlet 3. When the cleaning robot moves to the left, the first liquid outlet assembly 61 sprays cleaning fluid onto the working surface, and the cleaning assembly cleans this part of the working surface.

[0062] like Figure 6As shown, in one embodiment of this disclosure, the cleaning robot further includes a control unit. In the first motion posture, the control unit is configured to control only the second liquid dispensing component 62 to be energized during the downward movement of the cleaning robot, so as to dispense liquid onto the working surface below the cleaning robot; and to control the first liquid dispensing component 61 and the second liquid dispensing component 62 to be de-energized during the upward movement of the cleaning robot.

[0063] Specifically, the cleaning robot is also equipped with a control unit, which controls the energization and de-energization of the first liquid dispensing component 61 and the second liquid dispensing component 62. When the robot 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 second liquid dispensing component 62 to be energized and the first liquid dispensing component 61 to be de-energized. At this time, the second liquid dispensing component 62 can dispense liquid onto the working surface below the cleaning robot. During the upward movement of the cleaning robot, the control unit controls the first liquid dispensing component 61 and the second liquid dispensing component 62 to be de-energized. Neither the first liquid dispensing component 61 nor the second liquid dispensing component 62 dispenses liquid, thereby preventing gas from entering the inner cavity of the liquid storage device 2 from the first liquid dispensing component 61. This also makes the inward atmospheric pressure at the second liquid dispensing component 62 higher than the outward pressure of the liquid inside the second liquid dispensing component 62, effectively preventing the second liquid dispensing component 62 from dripping.

[0064] In the above embodiments of liquid dispensing components using atomization vibration, when the atomizing plate is energized, it vibrates to atomize the liquid and spray it out from the corresponding liquid outlet; when the atomizing plate is de-energized, the liquid remains in the affected pipeline and will not be sprayed out from the corresponding liquid outlet.

[0065] like Figure 7 As shown, in one embodiment of this disclosure, the cleaning robot further includes a control unit. In the second motion posture, the control unit is configured to control the first liquid dispensing component 61 to be energized when the cleaning robot moves toward the side where the first liquid dispensing component 61 is located; and to control the second liquid dispensing component 62 to be energized when the cleaning robot moves toward the side where the second liquid dispensing component 62 is located.

[0066] Specifically, when the robot body 1 is in the second motion posture, the control unit can control the energization and de-energization of the first liquid dispensing component 61 and the second liquid dispensing component 62 according to the direction of travel of the cleaning robot. For example, the first liquid dispensing component 61 is located on the left side of the robot body 1. When the cleaning robot moves to the left, the control unit controls the first liquid dispensing component 61 to be energized, and the first liquid dispensing component 61 dispenses liquid onto the working surface on the left side of the cleaning robot. The cleaning component then cleans the working surface after the liquid dispensing. The second liquid dispensing component 62 is located on the right side of the robot body 1. When the cleaning robot moves to the right, the control unit controls the second liquid dispensing component 62 to be energized, and the second liquid dispensing component 62 dispenses liquid onto the working surface on the right side of the cleaning robot. The cleaning component then cleans the working surface after the liquid dispensing.

[0067] The cleaning robot disclosed herein can operate on a glass surface in a first motion posture, such as moving up or down on the glass surface and cleaning it during the movement; it can also operate on a glass surface in a second motion posture, such as moving left or right on the glass surface and cleaning it during the movement. When the cleaning robot is working in the second motion posture, two liquid dispensing components are located on the left and right sides of the cleaning robot. When the cleaning robot moves to the left, the liquid dispensing component on the left side of the cleaning robot is controlled to dispense liquid onto the working surface on the left side of the cleaning robot; when the cleaning robot moves to the right, the liquid dispensing component on the right side of the cleaning robot is controlled to dispense liquid onto the working surface on the right side of the cleaning robot. When the cleaning robot moves to a predetermined position on the glass surface or is controlled 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. This allows the cavity 13 to isolate the liquid from the first liquid dispensing component 61 to the first water outlet 3, preventing the liquid from leaking from the lower second liquid dispensing component 62.

[0068] like Figures 2 to 5 As shown, in one embodiment of this disclosure, the first outlet 3 is disposed on the side wall of the liquid storage device 2, and the baffle 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, together with 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 opening end 12 between its free end and the side wall of the liquid storage device 2.

[0069] Specifically, the first outlet 3 is located on the side wall of the liquid storage device 2 and communicates with the inner cavity of the liquid storage device 2. A baffle device 5 is located adjacent to the liquid storage device 2. The baffle device 5 includes a semi-enclosed side wall 51, a bottom wall, and a top wall. The side wall of the liquid storage device 2, together with the enclosing side wall 51, bottom wall, and top wall of the baffle device 5, form a cavity 13. An opening 12 is formed between the free end of the enclosing side wall 51 and the side wall of the liquid storage device 2, thus allowing for... Figure 6 As shown, when the body 1 is in the first posture, the liquid in the first outlet 3 can only flow back into the cavity 13 and cannot flow back from the opening end 12 of the cavity 13 into the inner cavity of the liquid storage device 2, so that the first outlet 3 is always full of water, isolating the inner and outer atmosphere of the first outlet 3, preventing gas from entering the inner cavity of the liquid storage device 2 from the first outlet 3, and thus making the atmospheric pressure inward at the second outlet 4 higher than the pressure of the liquid outward inside the second outlet 4, effectively preventing the second outlet 4 from dripping.

[0070] like Figures 2 to 3 As shown, in one embodiment of this disclosure, the liquid storage device 2 includes an upper housing 23 and a lower housing 24; after the upper housing 23 and the lower housing 24 are fastened together, the upper housing 23, the partition device 5, and the lower housing 24 are configured to enclose each other to form a cavity 13.

[0071] Specifically, the liquid storage device 2 consists of an upper shell 23 and a lower shell 24 that interlock. The baffle device 5 can be configured such that one part is located within the upper shell 23 and the other part within the lower shell 24, which helps ensure the stability and sealing of the internal structure of the liquid storage device 2. Simultaneously, by rationally allocating the position of the baffle device 5, the flow and distribution of the cleaning fluid can be effectively managed and controlled, 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 on the upper shell 23 and the lower shell 24 is constructed to enclose each other, forming a sealed cavity 13, thereby blocking the gas passage between the first outlet 3 and the inner cavity of the liquid storage device 2. In another embodiment of this disclosure, the baffle device 5 can also be configured as a separate, integrally molded structure, with a sealing component provided in the portion of the baffle device 5 that encloses the upper shell 23 and the lower shell 24, thereby improving the sealing performance of the liquid storage device 5.

[0072] like Figures 2 to 7 As shown, in one embodiment of this disclosure, the liquid storage device 2 includes a main housing 21, which is configured to be disposed on one side of the body 1; when in the first motion posture, the opening end 12 is located on the upper side of the main housing 21 and is configured to face the upper side of the main housing 21.

[0073] Specifically, the liquid storage device 2 includes a main housing 21 and an extension housing 22 that are interconnected. When the machine body 1 is in the first motion posture, the main housing 21 is located on one side of the machine body 1. A first liquid outlet assembly 61 is located on this side corresponding to the main housing 21. The first liquid outlet assembly 61 is connected to the first water outlet 3 through a first water inlet pipe 7. A liquid injection hole 9 and a liquid injection plug 10 are also provided on the main housing 21. The liquid injection hole 9 is configured to inject cleaning liquid into the main housing 21, and the liquid injection plug 10 is configured to cooperate with the liquid injection hole 9 to ensure that the liquid injection hole 9 can be sealed when no liquid is 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 machine body 1. A second liquid outlet assembly 62 is located on the side of the machine body 1 opposite to the first liquid outlet assembly 61 and is connected to the second water outlet 4 on the extension housing 22 through a second water inlet pipe 8.

[0074] In one embodiment of this disclosure, the connection between the extension box 22 and the main box 21 is set as an arc-shaped structure, so that there is a certain height between the extension box 22 and the main box 21. Under the action of gravity, the cleaning liquid tends to flow from the main box 21 to the extension box 22, which is conducive to the collection of the cleaning liquid into the extension box 22.

[0075] When in the first motion posture, the main housing 21 is located on the upper side of the body 1, and the opening end 12 is located on the upper side of the main housing 21 and faces the upper side of the main housing 21. The cleaning fluid in the main housing 21 flows to the extension housing 22 under the action of gravity, and flows out from the second outlet 4 of the extension housing 22, enters the second liquid outlet assembly through the second water inlet pipe 8, and the second liquid outlet assembly discharges liquid to the working surface below the body 1, and the cleaning assembly cleans this part of the working surface. In this motion posture, the first outlet 3 has a tendency to flow back, but since the opening end 12 faces the upper side of the main tank 21 and the top of the opening end 12 is higher than the top of the first outlet 3, the liquid in the first outlet 3 cannot flow out of the opening end 12 and into the inner cavity of the main tank 21, thus isolating the inner and outer atmosphere of the first outlet 3 and preventing gas from entering the inner cavity of the liquid storage device 2 from the first outlet 3. As a result, the atmospheric pressure inward at the second outlet 4 is higher than the pressure of the liquid outward inside the second outlet 4, effectively preventing the second outlet 4 from dripping.

[0076] like Figures 2 to 3 As shown, in one embodiment of this disclosure, the position of the main tank 21 adjacent to the first outlet 3 is configured to extend outward to form an extension chamber 212 communicating with the main tank chamber 211, the baffle device 5 is configured to extend from the position of the main tank chamber 211 into the extension chamber 212, and the opening end 12 is configured to be located in the extension chamber 212.

[0077] Specifically, the main housing 21 includes a main housing chamber 211 and an extension chamber 212. The extension chamber 212 is located near the first outlet 3 of the main housing 21 and extends outward relative to the main housing 21. The baffle device 5 extends from the main housing chamber 211 into the extension chamber 212, with its opening end 12 located inside the extension chamber 212. Thus, 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, and the liquid in the main housing chamber 211 tends to flow downward. At this time, the extension chamber 212 contains air. Therefore, in addition to the chamber 13 preventing the liquid from flowing back from the first outlet 3 to the liquid storage device, the negative pressure environment in the inner cavity 13 of the liquid storage device can be further improved, thereby preventing the second liquid outlet component 62 from dripping.

[0078] like Figure 1 , Figures 5 to 7 As shown, in another embodiment of this 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 is constructed to have a first motion posture that moves along the height direction on the working surface and a second motion posture that moves along the horizontal direction. The liquid storage device 2 is disposed inside the body 1 and is provided with at least a first outlet 3 and a second outlet 4 communicating with its inner cavity. A baffle device 5 is provided in the liquid storage device 2 near the first outlet 3. When the body 1 switches from the second motion posture to the first motion posture, the baffle device 5 is configured to prevent liquid from flowing back into the inner cavity of the liquid storage device 2 through the first outlet 3.

[0079] Specifically, the cleaning robot provided in this 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 moving along the height direction on the working surface, and a second motion posture moving along the horizontal direction. A first outlet 3 and a second outlet 4 are provided at both ends of the liquid storage device 2. Both the first outlet 3 and the second outlet 4 are connected to the liquid storage device 2. The cleaning liquid in the liquid storage device 2 is output through the first outlet 3 and the second outlet 4 to clean the working surface. When the body 1 switches from the second motion posture to the first motion posture, since the height of the opening end 12 of the cavity 13 formed by the baffle device 5 is higher than the height of the first outlet 3, the baffle device 5 can isolate the internal and external atmosphere of the first outlet 3, preventing gas from entering the inner cavity of the liquid storage device 2 through the first outlet 3. This results in the atmospheric pressure inside the second outlet 4 being higher than the pressure of the liquid inside the second outlet 4 flowing outward, effectively preventing dripping from the second outlet 4.

[0080] like Figure 5As shown, in another embodiment of this disclosure, the baffle device 5 is configured to form a cavity 13 that surrounds the first outlet 3 and has an open end 12; the first outlet 3 is configured to communicate with the inner cavity of the liquid storage device 2 through the open end 12.

[0081] Specifically, a baffle device 5 is provided in the liquid storage device 2 near the first outlet 3. The baffle device 5 surrounds the first outlet 3 to form a cavity 13, and the cavity 13 has an open end 12. The first outlet 3 is connected to the inner cavity of the liquid storage device 2 through the open end 12.

[0082] like Figure 6 As shown, in another embodiment of this disclosure, when in the first motion posture, the first outlet 3 is configured to be located above the second outlet 4, and the opening end 12 of the cavity 13 is configured to be located above the first outlet 3, so as to prevent liquid from flowing back into the inner cavity of the liquid storage device 2 through the first outlet 3.

[0083] like Figure 6 As shown, when the robot body 1 is in the first motion posture, that is, during the upward or downward movement of the cleaning robot on the working surface, the first water outlet 3 is always located above the second water outlet 4, and the opening end 12 of the cavity 13 is located higher than the first water outlet 3, thereby preventing liquid from flowing back into the inner cavity of the liquid storage device 2 through the first water outlet 3. This keeps the first water outlet 3 full of water, thus isolating the inside and outside of the first water outlet 3 from the atmosphere, preventing gas from entering the inner cavity of the liquid storage device 2 from the first water outlet 3. Consequently, the atmospheric pressure at the second water outlet 4 is higher than the pressure of the liquid inside the second water outlet 4, effectively preventing liquid from dripping from the second water outlet 4.

[0084] The cleaning robot provided in this disclosure, by incorporating a baffle device within the liquid storage device, prevents liquid from flowing back into the inner cavity of the liquid storage device through the first outlet when the cleaning robot moves upward or downward on the working surface. This keeps the first outlet full of water, isolating it from the atmosphere and preventing gas from entering the inner cavity of the liquid storage device. Consequently, the inward atmospheric pressure at the second outlet is higher than the outward pressure of the liquid inside the second outlet, effectively preventing dripping from the second outlet. When the cleaning robot moves to the left or right on the working surface, both the first and second outlets contain liquid, further isolating them from the atmosphere. This creates an inward atmospheric pressure at both the first and second outlets, which is higher than the outward pressure of the liquid inside the first and second outlets, thus preventing dripping from the first and second outlets.

However, those skilled in the art should understand that this disclosure is not limited to the described order of actions, because according to this disclosure, some steps can be performed in other orders or simultaneously.
