Description

Cleaning robots and cleaning systems

[0001] This application claims priority to Chinese patent applications filed with the China Patent Office on January 26, 2024, with application numbers 202420200498.5, 202420200543.7, 202410114314.8 and 202420199746.9, all of which have the name “Cleaning Robot and Cleaning System”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning robot and a cleaning system using the cleaning robot. Background Art

[0003] At present, people's demand for smart home appliances is increasing. For whole-house cleaning, cleaning robots are a widely used cleaning equipment. Cleaning robots can rely on artificial intelligence to automatically complete floor cleaning in the room. Moreover, cleaning robots are generally used in conjunction with a cleaning base station that is compatible with them. The cleaning base station can be used to collect dust, clean and charge the cleaning robot.

[0004] In related art, a cleaning robot comprises a body, a bracket, a drive wheel assembly, a roller brush, and a side brush assembly. The body and bracket are connected to define a suction channel and a dust inlet, which is connected to the suction channel. However, the side brush assembly generally extends beyond the body contour, making it easy for the cleaning robot to contact and recontaminate already cleaned areas during cleaning. Furthermore, the side brush assembly often includes flexible bristles, making it less than ideal for cleaning corners and along edges.

[0005] Summary of the Invention

[0006] The present application provides a cleaning robot and a cleaning system, and the cleaning robot has a good cleaning effect.

[0007] On the one hand, the present application provides a cleaning robot, including a casing assembly, a driving wheel assembly, a guide member, a shielding member and a driving mechanism. The casing assembly has an air suction channel and a dust suction inlet. The dust suction inlet is connected to the air suction channel. The driving wheel assembly is connected to the casing assembly and is used to drive the cleaning robot to move on the working surface. The guide member is movably connected to the casing assembly. The shielding member is movably connected to the casing assembly and is at least partially located on the front side of the dust suction inlet. The driving mechanism is connected to the casing assembly and is transmission-connected to the guide member and the shielding member. The driving mechanism is used to drive the guide member to switch between an extended state and a retracted state in the left and right directions, and to drive the shielding member to move relative to the casing assembly to change the opening area of ​​the dust suction inlet.

[0008] On the other hand, the present application provides a cleaning system, including a cleaning base station and the above-mentioned cleaning robot, and the cleaning robot is used to dock with the cleaning base station.

[0009] In the cleaning robot and cleaning system provided in the embodiments of the present application, the cleaning robot includes a guide member and a shielding member, wherein the guide member can switch between an extended state and a retracted state in the left and right directions to flexibly adapt to different scenarios. For example, when cleaning along the edges or corners, the guide member switches to the extended state, and the airflow, under the guidance of the guide member, can suck the garbage on the wall or corner to the dust suction inlet and then into the suction channel, greatly improving the cleaning effect of the wall or corner area; when cleaning areas other than the wall or corner, the guide member can switch to the retracted state, so that it is not easy to collide and interfere with other objects placed in the cleaning area, thereby not affecting the passability of the cleaning robot. Of course, when the guide member is in the retracted state, secondary pollution of the cleaned area can also be avoided.

[0010] Moreover, the cleaning robot provided by the embodiment of the present application can also change the opening area of ​​the dust suction inlet through the movement of the covering member, thereby changing the opening size of the dust suction inlet. For different cleaning environments, the covering member adaptively adjusts the opening area of ​​the dust suction inlet through movement, thereby adjusting the suction force of the cleaning robot, so that the cleaning robot provided by the embodiment of the present application has a wider range of applications, and thus the cleaning effect of the cleaning robot provided by the embodiment of the present application is better.

DETAILED DESCRIPTION

[0027] In the related art, a cleaning robot comprises a body, a bracket, a driving wheel assembly, a roller brush, and a side brush assembly. The body and the bracket are connected to define an air suction channel and a dust suction inlet. The dust suction inlet is connected to the air suction channel, and there is a certain distance between the dust suction inlet and the working surface. The driving wheel assembly is connected to the body, the roller brush is rotatably connected to the bracket, and the side brush assembly is arranged at the bottom of the body and located in front of the roller brush. The side brush assembly is mainly used to gather garbage on the cleaning path of the roller brush and for cleaning corners and edges. However, on the one hand, the side brush assembly generally exceeds the outline of the body. When the cleaning robot performs a cleaning task, the side brush assembly is likely to contact the cleaned area, thereby re-contaminating the cleaned area. On the other hand, the side brush assembly mostly includes flexible bristles. In terms of cleaning corners and edges, the cleaning effect of the side brush assembly has always been less than ideal.

[0028] Therefore, this embodiment provides a cleaning robot and a cleaning system, wherein the cleaning robot has a better cleaning effect.

[0029] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] Referring to Figures 1 to 3, Figure 1 is a cross-sectional view of a cleaning robot according to an embodiment of the present application in one state of use, Figure 2 is a cross-sectional view of a cleaning robot according to an embodiment of the present application in another state of use, and Figure 3 is a schematic structural diagram of a partial structure of a cleaning robot according to an embodiment of the present application. As shown in Figures 1 to 3, this embodiment provides a cleaning robot 100, comprising a housing assembly 1, a drive wheel assembly 2, and a dust box 4.

[0031] Please refer to Figures 4 and 5. Figure 4 is a schematic diagram of the structure of Figure 3 from another perspective; Figure 5 is a schematic diagram of the structure of Figure 3 from yet another perspective. The housing assembly 1 has a suction channel 13 and a dust inlet 14. The dust inlet 14 is connected to the suction channel 13. The driving wheel assembly 2 is connected to the housing assembly 1 and is used to drive the cleaning robot 100 to move on the working surface 200. The dust box 4 is mounted on the housing assembly 1. The dust box 4 has a dust suction port. The suction channel 13 has an air outlet. The dust suction port and the air outlet are connected. Furthermore, the dust box 4 is connected to the suction channel 13.

[0032] Among them, the casing assembly 1 can be an integrated structure, or it can be formed by multiple parts that are detachably connected together. When the casing assembly 1 is an integrated structure, the casing assembly 1 can be formed by injection molding; when the casing assembly 1 is formed by multiple parts that are detachably connected together, the connection method between the multiple parts can be a snap connection, connection through fasteners, etc.

[0033] Generally, in order to maintain the appearance of the housing assembly 1 and to reduce the weight of the cleaning robot 100, the housing assembly 1 can be made of plastic. In this embodiment, there is no specific limitation on the material of the housing assembly 1.

[0034] During the operation of the cleaning robot 100, the garbage on the working surface 200 needs to enter from the dust suction inlet 14. Therefore, the dust suction inlet 14 is formed at the bottom of the suction channel 13. The garbage will enter the dust box 4 after passing through the suction channel 13. During the operation of the cleaning robot 100, the garbage on the working surface 200 will pass through the dust suction inlet 14 and the suction channel 13 in turn and then fall into the dust box 4.

[0035] The cleaning robot 100 also includes a roller brush 3; the casing assembly 1 includes a body 11 and a bracket 12, the bracket 12 is connected to the bottom of the body 11, the body 11 is formed with an inner cavity 111, the dust box 4 is arranged in the inner cavity 111, and the bottom of the body 11 is formed with an upwardly concave receiving cavity 112 for accommodating the bracket 12, the driving wheel assembly 2 is connected to the body 11, the roller brush 3 is rotatably connected to the bracket 12 and exposed from the dust suction inlet 14, and the roller brush 3 is used to contact the working surface 200 to clean the garbage on the working surface 200.

[0036] It is understandable that the roller brush 3 is a cleaning component used to contact the working surface 200 to clean the working surface 200. During the operation of the cleaning robot 100, the roller brush 3 will rotate relative to the bracket 12. Moreover, in order to realize the functions of the cleaning robot 100 such as obstacle crossing, the roller brush 3 will be lifted or lowered together with the bracket 12 under specific cleaning environments. The lifting and lowering of the roller brush 3 can be passive, such as floating up and down under the action of an uneven working surface, or it can be active. For active lifting, the structure that drives the roller brush 3 and the bracket 12 to rise and fall together can share some structure with the structure that drives the roller brush 3 to rotate, or it can be a driving structure that is set independently of the structure that drives the roller brush 3 to rotate. Here, there is no specific limitation on the structure that drives the roller brush 3 to rotate and the structure that drives the roller brush 3 and the bracket 12 to rise and fall together. It is understandable that for a cleaning robot with a pure suction function, both the cleaning component and the bracket 12 can be omitted.

[0037] Among them, the bracket 12 can include a bracket body 122 and a cover body 123, the bracket body 122 is connected to the fuselage 11, the cover body 123 is detachably connected to the bracket body 122, the bracket body 122 and the cover body 123 are connected to define a roller brush cavity 121 to position the roller brush 3, and the roller brush 3 and the bracket body 122 and the cover body 123 define an air suction channel 13 and a dust suction inlet 14.

[0038] Since the driving wheel assembly 2 needs to drive the cleaning robot 100 to move on the working surface 200, the driving wheel assembly 2 is arranged at the bottom of the casing assembly 1. The driving wheel assembly 2 may include two driving wheels 21 distributed in the left and right directions. The driving wheel 21 is rotatably connected to the bottom of the casing assembly 1. During the operation of the cleaning robot 100, the driving wheel 21 rotates around its own central axis, driving the cleaning robot 100 to move on the working surface 200.

[0039] In the following description, the direction of movement of the cleaning robot 100 driven by the driving wheel 21 in Figures 1 and 2 is defined as the front-to-back direction, and the left-to-right direction is based on the forward direction of the cleaning robot 100. The position on the left side of the fuselage 11 is the left side of the cleaning robot 100, and the position on the right side of the fuselage 11 is the right side of the cleaning robot 100. The left-to-right direction is perpendicular to the front-to-back direction, and in Figures 1 and 2, it is the direction perpendicular to the paper surface in the diagram.

[0040] In the first embodiment, the cleaning robot 100 is provided with a guide member 8, which is movably connected to the housing assembly 1 and can switch between an extended state and a retracted state in the left and right directions relative to the housing assembly 1. By providing the guide member 8, this embodiment allows the cleaning robot 100 provided in this embodiment to be flexibly applied to different scenarios. For example, when cleaning along edges or corners, the guide member 8 is switched to the extended state. Under the guidance of the guide member 8, the airflow can suck the garbage on the wall or corner to the dust suction inlet 14 and then into the air suction channel 13, greatly improving the cleaning effect of the wall or corner area; for example, when cleaning an open area, the guide member 8 is switched to the retracted state to avoid secondary contamination of the cleaned area.

[0041] It should be noted that, when the flow guide member 8 is in the retracted state, the flow guide member 8 may be completely hidden relative to the housing assembly 1 , or a portion of the structure of the flow guide member 8 may be exposed outside the housing assembly 1 .

[0042] Among them, when the guide member 8 can switch between the extended state and the retracted state in the left and right directions, it does not mean that the guide member 8 itself moves in the left and right directions. It can be understood that the free end of the guide member 8 is displaced in the left and right directions, that is, the position of the free end of the guide member 8 in the left and right directions is variable.

[0043] Based on this, in one implementation, the connection between the guide member 8 and the casing assembly 1 can be a sliding connection. Specifically, the guide member 8 can be slidingly connected to the fuselage 11, or it can be slidingly connected to the bracket 12. When the guide member 8 is slidingly connected to the bracket 12, it can be slidingly connected to the bracket body 122, or it can be slidingly connected to the cover body 123.

[0044] That is, when the cleaning robot 100 provided in this embodiment is cleaning along walls or corners, the guide member 8 needs to guide the airflow, and the guide member 8 can be slid relative to the casing assembly 1 to switch the guide member 8 to an extended state; when the cleaning robot 100 provided in this embodiment is cleaning an open area, the guide member 8 can be slid in the opposite direction relative to the casing assembly 1 to switch the guide member 8 to a retracted state.

[0045] Referring to Figures 6 to 8 , Figure 6 is a schematic diagram illustrating the structure of the housing assembly and the flow guide member in the cleaning robot provided in an embodiment of the present application. Figure 7 is a cross-sectional view taken along the AA direction of Figure 6 . Figure 8 is an enlarged schematic diagram of the partial structure at point B in Figure 7 . To achieve the sliding connection between the flow guide member 8 and the housing assembly 1, a chute 18 can be provided on the housing assembly 1, with the flow guide member 8 slidingly engaged with the chute 18. In this way, the chute 18 can guide the movement of the flow guide member 8 to a certain extent, improving the stability of the flow guide member 8 during movement and enhancing the performance of the cleaning robot 100 provided in this embodiment.

[0046] The chute 18 can be provided on the body 11 or the bracket 12. When the chute 18 is provided on the bracket 12, the deflector 8 and the bracket 12 form a module, which facilitates assembly. Specifically, the chute 18 can be provided on the bracket body 122 or the cover 123, or can be defined by the bracket body 122 and the cover 123.

[0047] In a specific implementation of this embodiment, the sliding groove 18 is defined by the support body 122 and the cover body 123 .

[0048] It should be noted that when the guide member 8 can be extended and retracted in the left and right directions relative to the casing assembly 1, in order for the slide groove 18 to play a certain guiding role on the guide member 8, the extension direction of the slide groove 18 is parallel to the left and right directions or the angle between it and the left and right directions is an acute angle.

[0049] In addition, in this embodiment, the extension direction of the guide member 8 can be parallel to the left and right directions, or it can be at an acute angle to the left and right directions. For example, the extension direction of the guide member 8 is the right front direction, the right rear direction, the left front direction or the left rear direction.

[0050] In another implementation, the flow guide member 8 and the housing assembly 1 may be connected in a rotational manner.

[0051] Specifically, the guide member 8 rotates around the connection with the housing assembly 1, and when extended, at least part of the guide member 8 is located outside the housing assembly 1. At this time, the moving path of the free end of the guide member 8 is an arc.

[0052] That is, when the cleaning robot 100 provided in this embodiment is cleaning along walls or corners, the guide member 8 needs to guide the airflow, and the guide member 8 can be rotated relative to the housing assembly 1 to switch the guide member 8 to an extended state; when the cleaning robot 100 provided in this embodiment is cleaning an open area, the guide member 8 can be rotated in the opposite direction relative to the housing assembly 1 to switch the guide member 8 to a retracted state.

[0053] As for the switching of the guide member 8 between the extended state and the retracted state relative to the casing assembly 1, it can be manually operated by the user. When the guide member 8 is slidingly connected to the casing assembly 1, the user can pull out or push back the free end of the guide member 8 to extend or retract the guide member 8; when the guide member 8 is rotationally connected to the casing assembly 1, the user can rotate the free end of the guide member 8 to extend or retract the guide member 8.

[0054] This method of switching the guide member 8 between the extended state and the retracted state is a passive method.

[0055] In some other embodiments, the guide member 8 can also be driven to switch between the extended state and the retracted state in an active manner, that is, a driving mechanism 10 connected to the housing assembly 1 can be provided, and the driving mechanism 10 is transmission-connected to the guide member 8 and is used to drive the guide member 8 to switch between the extended state and the retracted state.

[0056] The driving mechanism 10 may be connected to the body 11 or to the bracket 12. In some specific embodiments, the driving mechanism 10 is connected to the bracket 12.

[0057] Regarding the sliding connection between the guide member 8 and the casing assembly 1, the driving mechanism 10 may include a motor and a transmission assembly, the transmission assembly being connected to the motor, and the transmission assembly being driven to move by the rotation of the motor shaft of the motor, thereby driving the guide member 8 to move in one direction of extension or retraction; the driving mechanism 10 may also be a push rod motor or a cylinder, which drives the guide member 8 to move to move in one direction of extension or retraction.

[0058] The movement in the other direction of extension or retraction can be achieved by the drive mechanism 10 or by other means.

[0059] For example, in some embodiments, the driving mechanism 10 includes a driving component and a first reset component 30; the driving component is connected to the casing component 1, and the driving component is transmission-connected to the flow guide member 8, and the driving component is used to drive the flow guide member 8 to move relative to the casing component 1; the first reset component 30 is pressed between the casing component 1 and the flow guide member 8, and the first reset component 30 is used to reset the flow guide member 8.

[0060] When the driving assembly drives the flow guide 8 to extend relative to the housing assembly 1, the first return member 30 drives the flow guide 8 to retract relative to the housing assembly 1; when the driving assembly drives the flow guide 8 to retract relative to the housing assembly 1, the first return member 30 can drive the flow guide 8 to extend relative to the housing assembly 1. The first return member 30 here can be a spring.

[0061] In some other embodiments, the driving mechanism 10 may only include a driving component. In this case, the driving component is used to drive the guide member 8 to move relative to the casing component 1. The movement here can be understood as extending or retracting relative to the casing component 1. For example, the driving component drives the guide member 8 to extend relative to the casing component 1, and when retracting, the guide member 8 can be retracted by passive means such as manual operation; or, the driving component drives the guide member 8 to retract relative to the casing component 1, and when extending, the guide member 8 can be extended by passive means such as manual operation.

[0062] In addition, when the driving mechanism 10 only includes the driving assembly, the extension and retraction of the air guide 8 relative to the housing assembly 1 can also be achieved by the driving assembly. That is, the driving mechanism 10 can drive the air guide 8 to complete both the extension and retraction actions.

[0063] Please refer to Figure 9, which is a schematic diagram of the three-dimensional structure of the flow guide member in the cleaning robot provided in an embodiment of the present application. The flow guide member 8 may include a main body 85 and a flow guide portion 86. The main body 85 extends into the housing assembly 1, slidably engages with the chute 18, and is connected to the drive assembly and the first return member 30. The flow guide portion 86 is located outside the housing assembly 1 at least when the flow guide member 8 is in the extended state.

[0064] That is, the driving mechanism 10 drives the main body 85 to expand and contract in the left-right direction, thereby driving the air guide portion 86 to expand and contract in the left-right direction, so that the air guide portion 86 guides the airflow.

[0065] When the flow guide member 8 is rotatably connected to the housing assembly 1, a driving mechanism 10 may be used. For example, a motor may be provided within the housing assembly 1 to drive the flow guide member 8 to rotate. The motor drives the main body 85 to rotate, thereby driving the flow guide portion 86 to rotate. The method for driving the flow guide member 8 to rotate is not specifically limited.

[0066] It is worth mentioning that, for the cleaning robot 100, a single flow guide 8 can be provided, with the free end of the flow guide 8 extending out of the left or right side of the housing assembly 1. Alternatively, two flow guides 8 can be provided, with the free ends of the two flow guides 8 extending out of the left and right sides of the housing assembly 1, respectively. Of course, in other embodiments, the number of flow guides 8 can be more than three, and the positions of the flow guides 8 can be arranged according to actual conditions, which will not be listed here one by one.

[0067] In some embodiments, to enhance the airflow guiding effect of the air guide 8 and thereby improve the cleaning efficiency of the cleaning robot 100 provided in this embodiment, an airflow inlet 83 may be formed on the air guide 8. The airflow inlet 83 communicates with the air suction channel 13. When the air guide 8 is extended, external airflow can flow into the air suction channel 13 through the airflow inlet 83. In this way, while guiding the airflow, garbage can also be sucked into the air suction channel 13 through the airflow inlet 83 and then into the dust box 4.

[0068] Generally, the cleaning robot 100 mostly moves forward. Therefore, when the deflector 8 is extended, at least a portion of the airflow inlet 83 is positioned forward. Furthermore, in this embodiment, the airflow inlet 83 is connected to the suction channel 13. This ensures that the orientation of the airflow inlet 83 is consistent with the direction of travel of the cleaning robot 100, allowing more garbage to be drawn into the suction channel 13 through the airflow inlet 83. In some embodiments, the airflow inlet 83 can be positioned completely forward to receive garbage from the front of the deflector 8. Alternatively, the airflow inlet 83 can have both a forward opening and a lateral opening connected to the forward opening to receive garbage from the front and sides of the deflector 8. The lateral opening is the aforementioned end opening at the free end of the deflector 8.

[0069] In a specific implementation of this embodiment, at least when the guide member 8 is in the extended state, the guide member 8 can abut against the working surface 200, thereby allowing garbage to enter the airflow suction port 83. More specifically, the inner wall surface of the airflow suction port 83 includes a first wall surface 831 and a second wall surface 832 that are connected to each other. The second wall surface 832 is located below the first wall surface 831. The second wall surface 832 is used to abut against the working surface 200 when the guide member 8 is in the extended state. Specifically, it can be that the lower edge of the second wall surface 832 contacts the working surface. Please refer to Figure 10, which is a flow diagram of the airflow guided by the guide member in the cleaning robot provided by the embodiment of the present application. As shown in the figure, the airflow after being guided by the airflow suction port 83 can be accumulated together and then flow to the suction channel 13. In other words, after being guided by the airflow suction port 83, the garbage can be accumulated together and sucked into the suction channel 13.

[0070] Among them, the second wall 832 in the airflow suction port 83 mainly plays a guiding role. Therefore, in this embodiment, the second wall 832 is made into a curved surface, so that the extension direction of the second wall 832 is consistent with the direction of the flow trend of the airflow during the flow process, thereby making the guiding effect of the second wall 832 better.

[0071] In other embodiments, the airflow inlet 83 can be omitted. Under the guiding effect of the outer surface of the guide member 8 itself, the garbage can be sucked into the suction channel 13 through the outer surface of the guide member 8. It can be understood that even without the airflow inlet 83, the outer surface of the guide member 8 itself can also form a guide surface with a certain guiding effect. In this way, even without the airflow inlet 83, the guide member 8 still has a certain guiding effect, thereby improving the cleaning efficiency of the cleaning robot 100 provided by this embodiment.

[0072] It is worth mentioning that, in this embodiment, the guide member 8 is made of soft rubber material and can also play a role in scraping the working surface 200 .

[0073] In order to further improve the cleaning efficiency of the cleaning robot 100 provided in this embodiment, and to enable the airflow flowing through the air guide 8 to quickly flow into the air suction channel 13, in some optional embodiments, the housing assembly 1 is further provided with a side suction port 17 connected to the air suction channel 13, and the opening of the side suction port 17 is arranged at an angle to the forward direction of the cleaning robot 100; when the air guide 8 is extended, the external airflow can flow to the side suction port 17 through the air guide 8. Specifically in this embodiment, the side suction port 17 is formed on one side of the dust suction inlet 14 in the left-right direction, that is, the side suction port 17 is connected to the dust suction inlet 14, that is, the airflow flows through the air suction port 83, the side suction port 17, the dust suction inlet 14, and the air suction channel 13 in sequence.

[0074] It should be noted that when the guide member 8 is connected to the bracket 12, the guide member 8 is located on the rear side of the dust suction inlet 14, and the guide member 8 itself can not only have the function of a side brush assembly, but also act as a ground scraper to guide dry garbage into the dust suction inlet 14.

[0075] It is not difficult to understand that in some optional embodiments, the airflow suction port 83 can also be directly connected to the suction channel 13 through the side suction port 17, that is, the airflow flows through the airflow suction port 83, the side suction port 17, and the suction channel 13 in sequence.

[0076] In other optional embodiments, the side suction port 17 can also be omitted, that is, the air flow suction port 83 is connected to the suction channel 13, or the air flow suction port 83 is directly connected to the dust suction inlet 14, that is, the air flow flows through the air flow suction port 83 and the suction channel 13, or flows through the air flow suction port 83 and the dust suction inlet 14.

[0077] In order to facilitate the molding of the flow guide 8, the flow guide 8 is an integrated structure. For example, the flow guide 8 is formed by injection molding. Here, there is no specific limitation on the molding method of forming the flow guide 8.

[0078] In the second embodiment, the cleaning robot 100 is provided with a shielding member 9, which is movably connected to the housing assembly 1 and can move relative to the housing assembly 1 to change the opening area of ​​the dust suction inlet 14. In this embodiment, the opening area of ​​the dust suction inlet 14 is adjusted by the shielding member 9, so that the cleaning robot 100 can adjust the suction force of the dust suction inlet 14 and adapt to various working scenarios.

[0079] The shielding member 9 can be connected to the body 11 or the bracket 12 , and the shielding member 9 is arranged in front of the roller brush 3 .

[0080] In this embodiment, the shielding member 9 can move relative to the housing assembly 1 to change the opening area of ​​the dust suction inlet 14. In one implementation form, the connection between the shielding member 9 and the housing assembly 1 can be a sliding connection.

[0081] That is, if it is necessary to reduce the opening area of ​​the dust suction inlet 14, the shielding member 9 can be slid relative to the casing assembly 1 to reduce the opening area of ​​the dust suction inlet 14; if it is necessary to increase the opening area of ​​the dust suction inlet 14, the shielding member 9 can be slid in the opposite direction relative to the casing assembly 1 to increase the opening area of ​​the dust suction inlet 14.

[0082] In one sliding mode, the shielding member 9 can move relative to the housing assembly 1 toward or away from the work surface 200 to change the opening area of ​​the dust inlet 14. When the shielding member 9 moves relative to the housing assembly 1 toward the work surface 200, the opening area of ​​the dust inlet 14 decreases; when the shielding member 9 moves relative to the housing assembly 1 toward away from the work surface 200, the opening area of ​​the dust inlet 14 increases. In other words, the shielding member 9 can slide relative to the housing assembly 1 in the up-down direction. That is, when the shielding member 9 slides relative to the housing assembly 1 toward the work surface 200, it can be understood as a downward movement; if it is necessary to increase the opening area of ​​the dust inlet 14, the shielding member 9 slides relative to the housing assembly 1 toward the work surface 200, which can be understood as an upward movement.

[0083] It is understandable that when the shielding member 9 is connected to the bracket 12 , the positional relationship between the shielding member 9 and the bracket 12 can be that the shielding member 9 is set on the inner surface of the bracket 12 or the outer surface of the bracket 12 .

[0084] In the specific implementation of this embodiment, the shielding member 9 is arranged on the outer surface of the bracket 12. In this way, the shielding member 9 can not only adjust the opening area of ​​the dust suction inlet 14, but also the shielding member 9 will not interfere with the cleaning member such as the roller brush 3 arranged in the bracket 12.

[0085] In some optional embodiments, to enhance the structural compactness of the cleaning robot 100 provided in this embodiment, when the outer surface of the bracket 12 is a curved surface, the surface of the shielding member 9 that contacts the bracket 12 should also be a curved surface that matches the contour of the bracket 12. In other words, in this embodiment, the inner surface of the shielding member 9 is a curved surface that matches the outer surface of the bracket 12. This not only improves the connection reliability between the shielding member 9 and the bracket 12, but also enhances the structural compactness of the cleaning robot 100 provided in this embodiment.

[0086] When the shielding member 9 slides up and down relative to the housing assembly 1 , both ends of the shielding member 9 may be slidably connected to the brackets 12 respectively.

[0087] Specifically, please refer to Figure 11, which is a schematic diagram of the three-dimensional structure of a shielding member in a cleaning robot provided by an embodiment of the present application. As shown in the figure, the shielding member 9 includes a shielding body 93 and two third connecting parts 95. The shielding body 93 extends in the left and right directions, so that it can cover a large part of the dust suction inlet 14, and the shielding body 93 slides with the outer wall surface of the bracket 12. Specifically, the outer wall surface of the bracket 12 is a curved surface, and the inner surface of the shielding body 93 is formed into a curved surface that matches the surface of the bracket 12. The two third connecting parts 95 are respectively located at the two ends of the shielding body 93 along its own extension direction and are slidably connected to the bracket 12. In this way, when the third connecting part 95 slides in the up and down direction on the bracket 12, the shielding body 93 slides up and down along the curved surface of the bracket 12.

[0088] In some other embodiments, the shielding member 9 may be connected to the bracket 12 at a location between its ends. For example, the shielding body 93 may be connected to the bracket 12, and the middle portion of the shielding body 93 may be connected to the bracket 12. In this case, the two third connecting portions 95 may be omitted. The location where the shielding member 9 connects to the bracket 12 is not specifically limited. When the middle portion of the shielding body 93 is connected to the bracket 12, a similar connection method between the third connecting portions 95 and the bracket 12 may be used.

[0089] When the shielding member 9 slides up and down relative to the housing assembly 1, the cleaning robot 100 may be in operation. When it encounters an obstacle, the shielding member 9 is pushed against the obstacle and adaptively lifted. After passing the obstacle, the shielding member 9 freely falls and resets due to gravity. This can improve the passability of the cleaning robot 100 during operation. For example, when the cleaning robot 100 needs to pass through a threshold or a step, it can effectively pass through by lifting the shielding member 9. It is understandable that since the shielding member 9 has the characteristic of sliding up and down relative to the housing assembly 1, the lifting of the shielding member 9 can also be completed by manual operation.

[0090] In addition, when the shielding member 9 slides up and down relative to the casing assembly 1, the cleaning robot 100 can also be provided with an elastic member, which can be in the form of a spring, a shrapnel, an elastic block, etc. The elastic member can be connected between the shielding member 9 and the fuselage 11, or it can be connected between the shielding member 9 and the bracket 12.

[0091] The function of the elastic member is to provide downward pre-pressure to the shielding member 9. In this way, when the cleaning robot 100 encounters an obstacle such as a step during operation, the step will have an upward push-up effect on the shielding member 9. Specifically, the step will hit the shielding body 93, causing the shielding member 9 to rise, which will increase the opening area of ​​the dust suction inlet 14, so that the cleaning robot 100 can pass through the step efficiently. After passing the step, the shielding member 9 falls and resets under the drive of the elastic member.

[0092] The above content describes an embodiment in which the shielding member 9 moves passively when the shielding member 9 slides up and down relative to the housing assembly 1 .

[0093] In other embodiments, the cleaning robot 100 may also be provided with a driving mechanism 10, which is connected to the housing assembly 1 and is transmission-connected to the shielding member 9. The driving mechanism 10 is used to drive the shielding member 9 to move relative to the housing assembly 1 to change the opening area of ​​the dust inlet 14.

[0094] In the case of being provided with the driving mechanism 10, the cleaning robot 100 can be applied to more complex working scenarios. For example, when the cleaning robot 100 needs to pass through obstacles such as steps and thresholds, the driving mechanism 10 can actively drive the shielding member 9 to rise, thereby increasing the distance between the shielding member 9 and the working surface. In this process, the opening area of ​​the dust suction inlet 14 is also increased accordingly, so that it can pass quickly. After passing through obstacles such as steps and thresholds, the driving mechanism 10 can drive the shielding member 9 to descend and reset. When there are foreign objects with larger particles such as building blocks and glass balls on the working surface of the cleaning robot 100, in order to prevent these foreign objects from being sucked in and blocking the air duct, the driving mechanism 10 can also drive the shielding member 9 to move downward to reduce the distance between the shielding member 9 and the working surface 200, thereby preventing these foreign objects from being sucked in.

[0095] In some embodiments, the drive mechanism 10 includes a drive assembly and a second reset member 40. The drive assembly is connected to the housing assembly 1. Specifically, the drive assembly can be mounted on the bracket 12 or the body 11, although this application does not limit this. The second reset member 40 can be positioned between the housing assembly 1 and the shielding member 9 and can be in the form of a spring, a spring, an elastic block, or the like. It is understood that the drive assembly is used to act on the shielding member 9 to perform the aforementioned active sliding action, while the second reset member 40 is used to reset the shielding member 9.

[0096] In some other embodiments, the driving mechanism 10 may only include a driving component, which acts on the shielding member 9 to perform the above-mentioned active sliding action. It can be understood that the driving component is used to drive the shielding member 9 to move in a direction away from or close to the working surface 200. Specifically, when the driving component is used to drive the shielding member 9 to move in a direction away from the working surface 200, for the case where the shielding member 9 moves in a direction close to the working surface 200, the shielding member 9 can be moved by passive means such as manual operation; when the driving component is used to drive the shielding member 9 to move in a direction close to the working surface 200, for the case where the shielding member 9 moves in a direction away from the working surface 200, the shielding member 9 can be moved by passive means such as manual operation.

[0097] In addition, when the driving mechanism 10 only includes a driving component, the driving component can also drive the shielding member 9 to complete the movement in two directions of approaching and moving away from the working surface 200.

[0098] In order to achieve a transmission connection between the drive assembly and the shielding member 9 , the shielding member 9 may further include a second drive portion 94 , the second drive portion 94 is connected to the shielding body 93 , and the drive mechanism 10 is in transmission cooperation with the second drive portion 94 .

[0099] In one embodiment, the drive assembly includes a drive member 101 and a pusher 102. The drive member 101 is connected to the housing assembly 1 and is in driving connection with the pusher 102. The second drive portion 94 of the shielding member 9 cooperates with the pusher 102. The drive member 101 is used to drive the pusher 102 to move the shielding member 9 toward or away from the working surface 200. The drive member 101 can be in the form of a motor, an electric cylinder, a pneumatic cylinder, etc.

[0100] In this embodiment, the movement directions of the pusher 102 and the shielding member 9 can be the same or different. Please refer to Figure 3 and Figure 12. Figure 12 is a three-dimensional structural diagram of another partial structure of the cleaning robot provided by the embodiment of the present application. For example, in the method shown in Figures 3 and 12, the movement directions of the pusher 102 and the shielding member 9 are different. For example, a first inclined surface 1027 can be set on the pusher 102, and a second inclined surface 91 can be set on the second driving part 94. The second inclined surface 91 slides with the first inclined surface 1027. In this way, the movement of the shielding member 9 is achieved by the extrusion of the first inclined surface 1027 and the second inclined surface 91. Under this setting form, in the method shown in Figures 3 and 12, the pusher 102 moves in the left and right direction, while the shielding member 9 moves in the up and down direction.

[0101] The inclination direction of the first inclined surface 1027 and the second inclined surface 91 can be the extension direction in FIG3 , as shown in FIG3 , the driving member 101 is located on the left side of the pushing member 102, the bottom end of the first inclined surface 1027 is located on the side close to the driving member 101, the top end of the first inclined surface 1027 is located on the side away from the driving member 101, the bottom end to the top end of the first inclined surface 1027 is inclined to the upper right, and the extension direction of the second inclined surface 91 is consistent with the extension direction of the first inclined surface 1027; or it can be the extension direction in FIG12 , as shown in FIG12 , the driving member 101 is located on the right side of the pushing member 102, the bottom end of the first inclined surface 1027 is located on the side close to the driving member 101, the top end of the first inclined surface 1027 is located on the side away from the driving member 101, and the bottom end to the top end of the first inclined surface 1027 is inclined to the upper left. It is worth mentioning that the left and right sides mentioned here are defined based on the forward direction of the cleaning robot, not the perspective shown in the figure.

[0102] It should be noted that, in the present embodiment, the driving member 101 can be a push rod motor or a cylinder, etc., whose output shaft can make linear motion in the left-right direction, thereby driving the pushing member 102 to make linear motion. In other embodiments, the driving member 101 can also be a rotary motor, whose output shaft makes rotary motion. The driving member 101 and the pushing member 102 are connected by a transmission structure, and the transmission structure is used to convert the rotary motion of the driving member 101 into the linear motion of the pushing member 102. The transmission structure can be a screw-nut pair, or a worm gear, etc., which is not limited here. As can be seen from Figures 3 and 12, the driving member 101 is installed on the housing assembly 1 in the left-right direction. This allows the driving mechanism 10 to fully utilize the space within the housing assembly 1 and reduce the space occupied in the height, that is, the vertical direction. This can reduce the height of the cleaning robot 100 as a whole, making it easier for the cleaning robot 100 to enter spaces such as under beds and sofas for cleaning, thereby increasing the use scenarios of the cleaning robot 100 in height space.

[0103] Please refer to Figure 13, which is a three-dimensional structural diagram of another partial structure of the cleaning robot provided in an embodiment of the present application. In this embodiment, the pushing member 102 and the shielding member 9 have the same movement direction. When the pushing member 102 and the shielding member 9 have the same movement direction, as exemplified in Figure 13, when the output shaft of the driving member 101 extends in the vertical direction, the shielding member 9 also moves in the vertical direction toward or away from the working surface 200. It is not difficult to understand that in the embodiment shown in Figure 13, the first inclined surface 1027 can be omitted.

[0104] In addition, when moving in the same direction, the pushing member 102 can also be omitted, that is, the driving member 101 is directly connected to the shielding member 9 to drive the shielding member 9 to move.

[0105] Furthermore, in this embodiment, the dust suction inlet 14 mainly includes a front opening and a bottom opening that are interconnected. The front opening is located in front of the bottom opening, and the bottom opening is used to face the work surface. The shielding member 9 is mainly used to block or open the front opening to change the opening area of ​​the dust suction inlet 14. It is understood that in other embodiments, the shielding member 9 can also move back and forth to block or open a portion of the bottom opening.

[0106] In another sliding manner, the shielding member 9 may slide left and right relative to the housing assembly 1 to shield or open the front opening; or may slide left and right relative to the housing assembly 1 to shield or open the bottom opening.

[0107] In other sliding modes, the shielding member 9 may be displaced in the up-down and left-right directions relative to the bracket 12 at the same time.

[0108] It is understandable that in left-right sliding and other sliding modes, the shielding member 9 can be manually adjusted, or provided with an elastic member structure to enable reset, or a driving mechanism 10 can also be provided to perform active action.

[0109] The above description exemplifies that the connection between the shielding member 9 and the housing assembly 1 is a sliding connection, so as to realize the movement of the shielding member 9 relative to the housing assembly 1 .

[0110] In the case where the cleaning robot 100 of the present application is provided with a shielding member 9, the shielding member 9 can move relative to the housing assembly 1, or the shielding member 9 and the housing assembly 1 can be rotatably connected to each other.

[0111] Referring to Figure 3 , in the case of a rotational connection, the shielding member 9 can be rotationally connected to the bracket 12 at both ends. The structure of the shielding member 9 can refer to the above-mentioned sliding connection embodiment. Specifically, the shielding member 9 includes a shielding body 93 and two third connecting portions 95. The two third connecting portions 95 are rotationally connected to the two sides of the bracket 12. Specifically, the third connecting portions 95 are provided with first adapter holes 951, and the bracket 12 has adapter shafts 19 at both ends that are rotationally connected to the corresponding first adapter holes 951. The rotational cooperation between the first adapter holes 951 and the adapter shafts 19 achieves the rotational connection between the shielding member 9 and the bracket 12.

[0112] When the shielding member 9 is rotatably connected to the bracket 12 , the shielding member 9 can be rotatably connected to the bracket body 122 or the cover body 123 .

[0113] Thus, the shielding member 9 can rotate around the rotating connection between the third connecting part 95 and the bracket 12 to change the opening area of ​​the dust suction inlet 14, so that the cleaning robot 100 has the performance of adjusting the suction force of the dust suction inlet 14 and can adapt to various working scenarios.

[0114] When the shielding member 9 and the housing assembly 1 are rotationally connected, the cleaning robot 100 can also be provided with a driving mechanism 10 to drive the shielding member 9 to actively rotate, and the specific structural form and connection method of the driving mechanism 10 can refer to the embodiment in which the shielding member 9 and the housing assembly 1 are slidingly connected, and will not be repeated here.

[0115] Similarly, when the shielding member 9 is rotatably connected to the housing assembly 1 and is provided with a drive mechanism 10, the cleaning robot 100 can be applied to more complex working scenarios. For example, when the cleaning robot 100 needs to pass through obstacles such as steps and thresholds, the drive mechanism 10 can actively drive the shielding member 9 to rise, thereby increasing the distance between the shielding member 9 and the working surface 200. During this process, the opening area of ​​the dust suction inlet 14 is also increased accordingly to enable quick passage; after passing through obstacles such as steps and thresholds, the drive mechanism 10 can drive the shielding member 9 to descend and reset. When there are larger particles of foreign matter such as building blocks and glass balls on the working surface 200, in order to prevent these foreign matter from being sucked in and blocking the air duct, the drive mechanism 10 can also drive the shielding member 9 to move downward to reduce the distance between the shielding member 9 and the working surface 200, thereby preventing these foreign matter from being sucked in.

[0116] In addition, when the shielding member 9 is rotatably connected to the housing assembly 1, the cleaning robot 100 may not be provided with a driving mechanism 10, and the shielding member 9 may be manually adjusted or the above-mentioned passive movement, which will not be repeated here.

[0117] In some embodiments, a stroke limiting structure may be provided between the shielding member 9 and the bracket 12 , and the stroke limiting structure is used to limit the movement stroke of the shielding member 9 .

[0118] Therefore, please refer to Figures 12 and 13. In this embodiment, the stroke limiting structure includes a strip hole 130 provided on the housing assembly 1. The strip hole 130 extends along the movement direction of the shielding member 9. The shielding member 9 is provided with a limiting portion 96, which is passed through the strip hole 130. Specifically, the strip hole 130 is provided on the bracket 12 and extends in the up-down direction. The limiting portion 96 is a limiting shaft provided at both ends of the second driving portion 94. The limiting shaft passes through the strip hole 130. When the limiting shaft abuts against the top end of the strip hole 130, the distance between the shielding member 9 and the working surface 200 is the farthest. When the limiting shaft abuts against the bottom end of the strip hole 130, the distance between the shielding member 9 and the working surface 200 is the shortest.

[0119] In order to facilitate the molding of the shielding member 9, the shielding member 9 is an integrated structure. For example, the shielding member 9 is formed by injection molding. Here, there is no specific limitation on the molding method of forming the shielding member 9.

[0120] In the third embodiment, the cleaning robot 100 is provided with both a flow guide 8 and a shielding member 9 . The movement directions, functions and specific structures of the flow guide 8 and the shielding member 9 may refer to the above two embodiments.

[0121] In the cleaning robot 100 provided in this embodiment, a guide member 8 and a shielding member 9 are provided, wherein the guide member 8 switches between an extended state and a retracted state in the left and right directions to flexibly adapt to different scenarios. For example, when cleaning along the edges or corners, the guide member 8 switches to the extended state. Under the guidance of the guide member 8, the airflow can suck the garbage on the wall or corner to the dust suction inlet 14 and then into the suction channel 13, which greatly improves the cleaning effect of the wall or corner area; for example, when cleaning in an open area, the guide member 8 switches to the retracted state to avoid secondary pollution of the cleaned area.

[0122] Moreover, the movement of the shielding member 9 can change the opening area of ​​the dust suction inlet 14, thereby changing the opening size of the dust suction inlet 14. For different cleaning environments, the shielding member 9 can perform adaptive movement to adjust the suction force of the cleaning robot 100, thereby expanding the scope of application of the cleaning robot 100 provided in this embodiment, and thus improving the cleaning effect of the cleaning robot 100 provided in this embodiment. For large particles of garbage, the shielding member 9 can reduce the size of the dust suction inlet 14 to block the large particles of garbage out, thereby avoiding the situation where the cleaning robot 100 sucks in large particles of garbage and becomes blocked or stuck and cannot work normally.

[0123] In some embodiments, the driving form for the guide member 8 and the shielding member 9 can be in the form of a common driving mechanism 10, and the driving mechanism 10 can drive the guide member 8 and the shielding member 9 to move simultaneously or not simultaneously.

[0124] When the deflector 8 and the shielding member 9 move simultaneously, the shielding member 9 reduces the opening area of ​​the dust suction inlet 14 as the deflector 8 extends, and increases the opening area of ​​the dust suction inlet 14 as the deflector 8 retracts. Furthermore, in some embodiments, the shielding member 9 can move toward or away from the work surface 200 while the deflector 8 extends; and the shielding member 9 can move toward or away from the work surface 200 while the deflector 8 retracts. The coordinated movement of the deflector 8 and the shielding member 9 is not limited.

[0125] Regarding the form of the shared driving mechanism 10, the driving mechanism 10 may be connected to one of the guide member 8 and the shielding member 9 and cooperate with the other one, that is, only one of the first reset member 30 and the second reset member 40 may be provided. The "cooperation" here means that the drive of the driving component only drives movement in one direction, while the other direction is reset by the reset member.

[0126] For example, the drive mechanism 10 includes a drive assembly and a reset member. The drive assembly is in transmission connection with the guide member 8 and is used to drive the guide member 8 to switch between an extended state and a retracted state in the left-right direction. The drive assembly is in transmission connection with the shielding member 9 and is used to drive the shielding member 9 to move in a first direction. The reset member abuts between the housing assembly 1 and the shielding member 9 and is used to reset the shielding member 9 in a direction opposite to the first direction. The drive assembly can refer to the form in the first embodiment or the second embodiment described above. For example, as shown in Figure 3, the drive assembly and the shielding member 9 are connected by a matching connection between the first inclined surface 1027 and the second inclined surface 91. In this case, it is only necessary to connect the push member 102 to the guide member 8. The reset member is the second reset member 40 in the second embodiment, and the first direction is the direction of approaching or moving away from the working surface 200.

[0127] Alternatively, the drive assembly is in transmission connection with the shielding member 9, and is used to drive the shielding member 9 to move relative to the housing assembly 1. The drive assembly is in transmission connection with the flow guide member 8, and is used to drive the flow guide member 8 to move in the second direction. The reset member abuts between the housing assembly 1 and the flow guide member 8 and is used to reset the flow guide member 8 in a direction opposite to the second direction. The drive assembly can still refer to the form of the second embodiment described above. In this case, the reset member is the first reset member 30 in the first embodiment, and the second direction is the extension direction or retraction direction of the flow guide member 8.

[0128] Please refer to Figures 14 and 15. Figure 14 is a schematic diagram of the connection between the drive mechanism and the flow guide member in the cleaning robot provided by an embodiment of the present application, and Figure 15 is an enlarged schematic diagram of the partial structure at point C in Figure 14. As shown in Figures 14 and 15, the pusher 102 has a boss 1024 connected to the flow guide member 8, and the axial direction of the boss 1024 can be consistent with the up-down direction. Accordingly, the flow guide member 8 has a connecting groove 81 for the boss 1024 to be inserted into. The boss 1024 and the connecting groove 81 can be connected together by bonding, clamping, etc., so that the pusher 102 can push the flow guide member 8.

[0129] Referring to Figure 3 , in the embodiment shown in Figure 3 , the first inclined surface 1027 slopes from the upper right to the lower left, so that when the driving member 101 drives the pushing member 102 to move rightward, the pushing member 102 can simultaneously drive the deflector 8 to extend rightward and drive the shielding member 9 downward. Of course, in other embodiments, depending on the type and location of the driving member 101, the extension direction of the deflector 8, etc., the first inclined surface 1027 can also be designed to slope from the upper left to the lower right. The inclination direction of the first inclined surface 1027 is not limited here.

[0130] Furthermore, in FIG3 , in addition to the drive assembly, namely the drive member 101 and the pusher 102, the drive mechanism 10 further includes a first reset member 30 and a second reset member 40. Specifically, the first reset member 30 of the first embodiment and the second reset member 40 of the second embodiment are provided simultaneously. Specifically, the first reset member 30 is used to reset the flow guide member 8, and the second reset member 40 is used to reset the shielding member 9. The configuration and type of the first reset member 30 and the second reset member 40 can refer to the above-described embodiment.

[0131] It should be noted that in some other embodiments, the first reset member 30 and the second reset member 40 may not be provided, that is, only the driving member 101 needs to be provided, which can be a motor, so as to realize the switching of the guide member 8 between the extended state and the retracted state, and to realize the movement of the shielding member 9.

[0132] In some other embodiments, the flow guide 8 and the shielding member 9 may also use separate driving mechanisms, or may not use a driving mechanism.

[0133] When a separate driving mechanism is used, the driving mechanisms in the above two embodiments may be both provided on the housing assembly 1 ; when no driving mechanism is used, the passive movement mode in the above embodiments may be referred to.

[0134] This embodiment also provides a cleaning system, comprising a cleaning base station and the cleaning robot 100 described in the above embodiment. The cleaning robot 100 is configured to dock with the cleaning base station. The cleaning base station may include a receiving cavity for the cleaning robot 100. The cleaning base station can charge the cleaning robot 100 and vacuum the dust box 4. The cleaning base station is not specifically limited herein. The cleaning robot 100 has been described in detail in the above embodiment and will not be further described here.
