[0033] The beneficial effects of the cleaning equipment provided in this application are as follows: Compared with the prior art, the cleaning equipment provided in this application, by correspondingly setting a first suction port and a second suction port on the front and rear sides of the first cleaning module, and setting the first suction port to stop sucking up dirt from the surface to be cleaned when the cleaning equipment moves forward, and setting the second suction port to stop sucking up dirt from the surface to be cleaned when the cleaning equipment moves backward, allows the cleaning equipment to control the suction of dirt from the first and second suction ports according to its direction of movement.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0040] As described in the background section, with the improvement of living standards, cleaning equipment with both wet and dry cleaning functions (e.g., carpet cleaning equipment) has been widely used in homes and commercial spaces. Existing cleaning equipment typically only considers the suction effect in one direction, neglecting the cleaning needs in the opposite direction, resulting in differences in cleaning effectiveness in different directions. Therefore, the cleaning capabilities of existing cleaning equipment need to be improved.

[0041] See Figures 1 to 14As shown, in order to solve the above problems, according to one aspect of this application, this application provides a cleaning device, which includes: a device body 10, a first cleaning module 20 and a first suction module 30. The first cleaning module 20 is disposed on the device body 10; the first suction module 30 is disposed on the device body 10 and has a first suction port 3111 and a second suction port 3121. Along the forward direction of the cleaning device, the first suction port 3111 is located in front of the first cleaning module 20, and the second suction port 3121 is located behind the first cleaning module 20; wherein, the first suction port 3111 stops sucking up dirt on the surface to be cleaned when the cleaning device moves forward, and the second suction port 3121 stops sucking up dirt on the surface to be cleaned when the cleaning device moves backward. The cleaning device features a first suction port 3111 and a second suction port 3121 positioned on the front and rear sides of the first cleaning module 20. The first suction port 3111 is configured to stop sucking up dirt from the surface to be cleaned when the cleaning device moves forward, and the second suction port 3121 is configured to stop sucking up dirt from the surface to be cleaned when the cleaning device moves backward. This allows the cleaning device to control the suction of dirt from the first and second suction ports 3111 and 3121 according to its direction of movement. Specifically, when the cleaning device moves forward, since the first suction port 3111 stops sucking up dirt from the surface to be cleaned, the first cleaning module 20 first contacts the surface to be cleaned to agitate the dirt. The cleaning liquid supply unit 22 outputs cleaning liquid, which mixes with the dirt. The agitated mixture is then sucked up by the second suction port 3121, preventing the first suction port 3111 from blocking the cleaning liquid supply unit 22. The suction of the newly output cleaning fluid also avoids interference from the first suction port 3111 on the forward cleaning process. When the cleaning device moves backward, since the second suction port 3121 stops sucking up dirt on the surface to be cleaned, the first cleaning module 20 first contacts the surface to be cleaned to agitate the dirt. The cleaning fluid supply unit 22 outputs cleaning fluid to mix with the dirt, and then the first suction port 3111 sucks up the agitated mixture. This avoids the second suction port 3121 sucking up the cleaning fluid just output by the cleaning fluid supply unit 22, and also avoids interference from the second suction port 3121 on the backward cleaning process. Compared with the existing cleaning devices that only consider the suction effect in one direction, the cleaning device of this application can achieve a better suction effect in both forward and backward bidirectional movement, thereby effectively improving the consistency of the cleaning ability of the cleaning device in different directions and improving the user experience.

[0042] It should be noted that the main body 10 refers to the basic load-bearing structure of the cleaning equipment, used to install and support the first cleaning module 20, the first suction module 30, and other functional modules; the first cleaning module 20 refers to the functional module installed on the main body 10, used to contact the surface to be cleaned to agitate or scrub dirt; the first suction module 30 refers to the functional module installed on the main body 10, used to guide dirt into the cleaning equipment for recycling, and it includes at least a first suction port 3111 and a second suction port 3121; the first suction port 3111 refers to the opening structure in the first suction module 30 located on the front side of the first cleaning module 20, used to allow dirt to enter the first suction module 30; the second suction port 3121 refers to the opening structure in the first suction module 30 located on the rear side of the first cleaning module 20, used to allow dirt to enter the first suction module 30. Another opening structure of module 30; the forward direction refers to the direction of movement of the cleaning equipment during normal cleaning operation; the backward direction refers to the direction of movement opposite to the forward direction; the first suction port 3111 stops sucking up dirt on the surface to be cleaned when the cleaning equipment moves forward, meaning that during the forward process of the cleaning equipment, the first suction port 3111 is in a non-working state, and the channel in the first suction module 30 connected to the first suction port 3111 is blocked, so that dirt cannot enter the recycling through the first suction port 3111; the second suction port 3121 stops sucking up dirt on the surface to be cleaned when the cleaning equipment moves backward, meaning that during the backward process of the cleaning equipment, the second suction port 3121 is in a non-working state, and the channel in the first suction module 30 connected to the second suction port 3121 is blocked, so that dirt cannot be recycled through the second suction port 3121.

[0043] It is understandable that the first suction port 3111 being located in front of the first cleaning module 20 means that the first suction port 3111 is located in front of the first cleaning module 20 along the forward direction of the cleaning equipment; the second suction port 3121 being located behind the first cleaning module 20 means that the second suction port 3121 is located behind the first cleaning module 20 along the forward direction of the cleaning equipment.

[0044] It should be noted that when the cleaning equipment is cleaning the surface to be cleaned, at least one of the first suction port 3111 and the second suction port 3121 needs to maintain the ability to suck up dirt on the surface to be cleaned to ensure that the dirt can be recovered in a timely manner. For example, when the cleaning equipment moves forward, the first suction port 3111 stops sucking up dirt on the surface to be cleaned while the second suction port 3121 maintains the ability to suck up dirt on the surface to be cleaned. When the cleaning equipment moves backward, the second suction port 3121 stops sucking up dirt on the surface to be cleaned while the first suction port 3111 maintains the ability to suck up dirt on the surface to be cleaned. When the cleaning equipment is stationary, at least one of the first suction port 3111 and the second suction port 3121 maintains the ability to suck up dirt on the surface to be cleaned.

[0045] See Figures 3 to 6 , Figure 9 and Figure 10 As shown, optionally, the first suction module 30 includes a first suction unit 31, which has a first channel section 311 and a second channel section 312 in fluid communication with the external environment. The first suction port 3111 is located in the first channel section 311, and the second suction port 3121 is located in the second channel section 312. By setting the first channel section 311 and the second channel section 312, and placing the first suction port 3111 in the first channel section 311 and the second suction port 3121 in the second channel section 312, the first suction port 3111 and the second suction port 3121 can be structurally relatively independent, thereby facilitating the cleaning equipment to control the suction of dirt from the first suction port 3111 and the second suction port 3121 according to the direction of movement.

[0046] It should be noted that the first suction unit 31 refers to the functional unit in the first suction module 30 used to form a suction channel, which has a first channel segment 311 and a second channel segment 312 that are in fluid communication with the external environment; the first channel segment 311 refers to the tubular or channel-like structure in the first suction unit 31 that is in fluid communication with the external environment; the second channel segment 312 refers to another tubular or channel-like structure in the first suction unit 31 that is in fluid communication with the external environment; the first suction port 3111 located in the first channel segment 311 means that the first suction port 3111 is set on the first channel segment 311 and forms an opening in the first channel segment 311 that is in communication with the external environment; the second suction port 3121 located in the second channel segment 312 means that the second suction port 3121 is set on the second channel segment 312 and forms an opening in the second channel segment 312 that is in communication with the external environment.

[0047] Optionally, the first suction port 3111 is located at the end of the first channel segment 311, that is, at the end of the first channel segment 311 closer to the surface to be cleaned; the second suction port 3121 is located at the end of the second channel segment 312, that is, at the end of the second channel segment 312 closer to the surface to be cleaned. Setting the first suction port 3111 at the end of the first channel segment 311 and the second suction port 3121 at the end of the second channel segment 312 helps to shorten the distance between the first suction port 3111 and the second suction port 3121 and the surface to be cleaned, reduces suction attenuation, and improves the suction efficiency of the first suction port 3111 and the second suction port 3121.

[0048] See Figure 3 and Figure 5As shown, optionally, the cleaning equipment also includes a first negative pressure module 40, which is in fluid communication with the first channel section 311 and the second channel section 312. By setting the first negative pressure module 40 and fluidly communicating it with the first channel section 311 and the second channel section 312, the cleaning equipment can provide a common suction power source for the first suction port 3111 and the second suction port 3121 through the first negative pressure module 40, thereby reducing the manufacturing cost and overall weight of the cleaning equipment.

[0049] It should be noted that the first negative pressure module 40 refers to a functional module installed on the cleaning equipment to generate negative pressure to provide suction power. The specific form of the first negative pressure module 40 includes, but is not limited to, a fan or a vacuum pump, which is in fluid communication with the first channel section 311 and the second channel section 312. The fluid communication between the first negative pressure module 40 and the first channel section 311 and the second channel section 312 means that the air inlet of the first negative pressure module 40 is connected to the first channel section 311 and the second channel section 312 respectively through fluid channels, so that the suction force generated by the first negative pressure module 40 can act on the first channel section 311 and the second channel section 312 simultaneously, thereby forming negative pressure at the first suction port 3111 and the second suction port 3121.

[0050] Optionally, the cleaning equipment also includes a waste recovery module 90, which is disposed on the main body 10 of the equipment. The first negative pressure module 40, the waste recovery module 90, and the first suction module 30 are connected in sequence. By setting up the waste recovery module 90, the sucked-in waste can be collected in a concentrated manner, preventing waste from directly entering the first negative pressure module 40 and causing pollution or damage. It also facilitates cleaning and maintenance by the user.

[0051] It should be noted that the sequential connection of the first negative pressure module 40, the waste recovery module 90, and the first suction module 30 means that the first negative pressure module 40, the waste recovery module 90, and the first suction module 30 are connected in series through a fluid channel, so that the suction force generated by the first negative pressure module 40 can act on the first suction module 30 through the waste recovery module 90, thereby sucking the waste from the first suction module 30 and collecting it into the waste recovery module 90.

[0052] It is understood that the waste recovery module 90 refers to a functional component installed on the main body 10 for collecting and temporarily storing waste sucked in by the first suction module 30. It can be in the form of a dust cup, dust bag, wastewater tank, or solid-liquid separation container. The waste recovery module 90 is sequentially connected to the first negative pressure module 40 and the first suction module 30 to form a complete suction circuit: the first negative pressure module 40 generates negative pressure, which is transmitted to the first suction module 30 through the waste recovery module 90, causing the waste to be sucked into the first suction module 30 with the airflow and then enter the waste recovery module 90. The waste is trapped in the waste recovery module 90, while the airflow continues to flow to the first negative pressure module 40 and is then discharged.

[0053] See Figure 4 , Figure 6 , Figure 9 and Figure 10 As shown, optionally, the first suction unit 31 has a third channel section 313, with the first channel section 311 and the second channel section 312 in fluid communication with the third channel section 313. The first negative pressure module 40 is in fluid communication with the first channel section 311 and the second channel section 312 through the third channel section 313. By setting the third channel section 313 as a common confluence channel for the first channel section 311 and the second channel section 312, the first negative pressure module 40 only needs to be connected to the third channel section 313 to provide suction power to both channel sections simultaneously, thereby simplifying the piping structure of the first suction module 30 and reducing the manufacturing cost of the cleaning equipment.

[0054] It should be noted that the third channel segment 313 refers to the shared channel structure in the first suction unit 31 that is fluidly connected to the first channel segment 311 and the second channel segment 312, respectively, and is used to collect dirt from the first channel segment 311 and the second channel segment 312; the fluid connection between the first channel segment 311 and the second channel segment 312 and the third channel segment 313 means that the air outlets of the first channel segment 311 and the second channel segment 312 are respectively connected to the third channel segment 313, so that the airflow in the first channel segment 311 and the second channel segment 312 can flow into the third channel segment 313; the fluid connection between the first negative pressure module 40 and the first channel segment 311 and the second channel segment 312 through the third channel segment 313 means that the air inlet of the first negative pressure module 40 is connected to the third channel segment 313, so that the suction force generated by the first negative pressure module 40 acts on the first channel segment 311 and the second channel segment 312 simultaneously through the third channel segment 313.

[0055] See Figure 9 and Figure 10As shown, optionally, the first suction module 30 further includes a first switch unit 33 and a second switch unit 34. The first switch unit 33 is disposed in the first channel section 311 and is used to control the fluid flow between the first suction port 3111 and the first negative pressure module 40. The second switch unit 34 is disposed in the second channel section 312 and is used to control the fluid flow between the second suction port 3121 and the first negative pressure module 40. By separately setting the first switch unit 33 and the second switch unit 34, the suction of dirt from the first suction port 3111 and the second suction port 3121 can be independently controlled. This allows the cleaning equipment to control the suction state of the first suction port 3111 or the second suction port 3121 according to the forward or backward movement direction, thereby realizing automatic switching of the suction ports during bidirectional cleaning.

[0056] It should be noted that the first switch unit 33 refers to the control component disposed on the first channel section 311 for controlling the fluid flow between the first suction port 3111 and the first negative pressure module 40; the second switch unit 34 refers to the control component disposed on the second channel section 312 for controlling the fluid flow between the second suction port 3121 and the first negative pressure module 40; the first switch unit 33 being disposed on the first channel section 311 means that the first switch unit 33 is installed on the first channel section 311 and forms a cooperative relationship with the first channel section 311 to control the fluid flow within the first channel section 311; the second switch unit 34 being disposed on the second channel section 312 means that the second switch unit 34 is installed on the second channel section 312 and forms a cooperative relationship with the second channel section 311 to control the fluid flow within the first channel section 311; 12. A cooperative relationship is formed to control the flow of fluid within the second channel segment 312; the first switch unit 33 controls the flow of fluid between the first suction port 3111 and the first negative pressure module 40 by operating the first switch unit 33, which enables the fluid channel between the first suction port 3111 and the first negative pressure module 40 to be in a conducting state or a blocked state, thereby achieving the switching of the suction state of the first suction port 3111; the second switch unit 34 controls the flow of fluid between the second suction port 3121 and the first negative pressure module 40 by operating the second switch unit 34, which enables the fluid channel between the second suction port 3121 and the first negative pressure module 40 to be in a conducting state or a blocked state, thereby achieving the switching of the suction state of the second suction port 3121.

[0057] Optionally, the first switching unit 33 includes a first solenoid valve connected in series in the first channel segment 311, and has a first open state and a first closed state. In the first open state, the first solenoid valve controls the movement of its valve core to open the first channel segment 311. In the first closed state, the first solenoid valve controls the movement of its valve core to close the first channel segment 311. The second switching unit 34 includes a second solenoid valve connected in series in the second channel segment 312, and has a second open state and a second closed state. In the second open state, the second solenoid valve controls the movement of its valve core to open the second channel segment 312. In the second closed state, the second solenoid valve controls the movement of its valve core to close the second channel segment 312. By connecting the first solenoid valve in series in the first channel segment and the second solenoid valve in series in the second channel segment, and using the movement of the valve cores of the two solenoid valves to control the opening and closing of the corresponding channel segments respectively, independent, rapid, and reliable control of the dirt suction state of the first and second suction ports is achieved, thereby providing an execution basis for the cleaning equipment to automatically switch the suction port according to the forward or backward direction.

[0058] It should be noted that the first switch unit 33 and the second switch unit 34 can also be mechanical valves or other valves that can control the opening and closing of the channel segment.

[0059] See Figure 4 and Figure 6 As shown, optionally, the first suction module 30 further includes a switching unit 32, which is connected to the transfer channel segment 314. The switching unit 32 has a first state and a second state. In the first state, the switching unit 32 connects the first channel segment 311 and the third channel segment 313 and disconnects the second channel segment 312 and the third channel segment 313. In the second state, the switching unit 32 connects the second channel segment 312 and the third channel segment 313 and disconnects the first channel segment 311 and the third channel segment 313. By setting the switching unit 32, the first channel segment 311 and the second channel segment 312 can be selectively switched on by a single switching unit 32. Compared with using two independent switching units to control the on and off of the first channel segment 311 and the second channel segment 312 respectively, selective switching by a single switching unit 32 can effectively reduce the number of control components in the first suction module 30, thereby simplifying the structure of the first suction module 30 to a certain extent, reducing the manufacturing cost of the cleaning equipment, and also facilitating the synchronous switching of the opening and closing of the first suction port 3111 and the second suction port 3121 during bidirectional forward and backward movement.

[0060] It should be noted that the switching unit 32 refers to a control component disposed on the transition channel section 314 for selectively connecting the first channel section 311 and the third channel section 313, or the second channel section 312 and the third channel section 313; the switching unit 32 having a first state and a second state means that the switching unit 32 can switch between two working states to achieve selective connection between the first channel section 311 and the second channel section 312 and the third channel section 313; in the first state, the switching unit 32 connects the first channel section 311 and the third channel section 313, and disconnects the second channel section 312 and the third channel section 313, meaning that when the switching unit 32 is in the first state, the fluid channel between the first channel section 311 and the third channel section 313 is in a connected state. When the switching unit 32 is in the second state, the fluid passage between the second channel segment 312 and the third channel segment 313 is blocked, allowing dirt to be collected by the cleaning equipment from the first suction port 3111 through the first channel segment 311 and the third channel segment 313. When the switching unit 32 is in the second state, the switching unit 32 connects the second channel segment 312 and the third channel segment 313, and the disconnection of the first channel segment 311 and the third channel segment 313 means that when the switching unit 32 is in the second state, the fluid passage between the second channel segment 312 and the third channel segment 313 is connected, while the fluid passage between the first channel segment 311 and the third channel segment 313 is blocked, allowing dirt to be collected by the cleaning equipment from the second suction port 3121 through the second channel segment 312 and the third channel segment 313.

[0061] See Figure 4 and Figure 6 As shown, optionally, the first suction unit 31 has a transfer channel section 314, and the third channel section 313 is fluidly connected to the first channel section 311 and the second channel section 312 through the transfer channel section 314; the switching unit 32 is disposed in the transfer channel section. By setting the transfer channel section 314, the first channel section 311 and the second channel section 312 can merge into the third channel section 313 through the transfer channel section 314, realizing the confluence structure of two independent suction channels, while providing space for the setting of the switching unit 32.

[0062] It should be noted that the transition channel section 314 refers to the transition channel structure in the first suction unit 31 used to connect the first channel section 311, the second channel section 312, and the third channel section 313, serving as the common interface for the first channel section 311 and the second channel section 312 to converge into the third channel section 313; the switching unit 32 being disposed on the transition channel section 314 means that the switching unit 32 is installed on the transition channel section 314 and forms a cooperative relationship with the transition channel section 314 to control the fluid flow direction within the transition channel section 314; when the switching unit 32 is in the first state, the waste can be recovered by the cleaning equipment from the first suction port 3111 through the first channel section 311, the transition channel section 314, and the third channel section 313; when the switching unit 32 is in the first state, the waste can be recovered by the cleaning equipment from the second suction port 3121 through the second channel section 312, the transition channel section 314, and the third channel section 313.

[0063] See Figures 2 to 8 As shown, optionally, the switching unit 32 includes a valve core component 321 and a drive assembly 322. The valve core component 321 is movably disposed within the transition channel section 314, and the drive assembly 322 is drivenly connected to the valve core component 321 to drive the valve core component 321 to block one of the first channel section 311 and the second channel section 312. By configuring the valve core component 321 and the drive assembly 322, the switching unit 32 can selectively block the first channel section 311 and the second channel section 312 through a single movable part, which is beneficial for the compact design of the cleaning equipment and also facilitates the rapid switching of the opening and closing of the first suction port 3111 and the second suction port 3121 during forward and backward bidirectional movement.

[0064] It should be noted that the valve core component 321 refers to the movable part in the switching unit 32 used for selectively blocking the first channel segment 311 or the second channel segment 312. It is located within the transition channel segment 314 and can move to different positions under the drive of the drive assembly 322 to block different channel segments. Its specific form includes, but is not limited to, plate-shaped valve core, column-shaped valve core, ball-shaped valve core, etc. The drive assembly 322 refers to the drive component that is drivenly connected to the valve core component 321 and used to provide the movement power for the valve core component 321. Its specific form includes, but is not limited to, an electric motor. Electromagnet; the valve core component 321 being movably disposed within the transition channel section 314 means that the valve core component 321 is installed inside the transition channel section 314 and can move within the transition channel section 314, such as rotating, sliding, or swinging, to change its position within the transition channel section 314; the drive assembly 322 being driven connected to the valve core component 321 means that the drive assembly 322 and the valve core component 321 are connected directly or indirectly, so that the power generated by the drive assembly 322 can be transmitted to the valve core component 321, thereby driving the valve core component 321 to move; Understandably, when the switching unit 32 is in the first state, the drive assembly 322 moves the valve core component 321 to the first position. At this time, the valve core component 321 blocks the connection between the first channel segment 311 and the transition channel segment 314, while keeping the second channel segment 312 connected to the transition channel segment 314. When the switching unit 32 is in the second state, the drive assembly 322 moves the valve core component 321 to the second position. At this time, the valve core component 321 blocks the connection between the second channel segment 312 and the transition channel segment 314, while keeping the first channel segment 311 connected to the transition channel segment 314.

[0065] See Figure 4 and Figure 6 As shown, optionally, the first channel segment 311 is perpendicular to the surface to be cleaned; by setting the first channel segment 311 to be perpendicular to the surface to be cleaned, the first suction port 3111 can face the surface to be cleaned in a direct manner, which is beneficial for dirt to be vertically sucked into the first channel segment 311, reducing the turning point of the airflow path, thereby improving the suction efficiency of the first suction port 3111.

[0066] It should be noted that the first channel segment 311 being perpendicular to the surface to be cleaned means that the extension direction of the first channel segment 311 is perpendicular to the plane where the surface to be cleaned is located. That is, the first channel segment 311 extends along the normal direction of the surface to be cleaned, so that the first suction port 3111 located at the end of the first channel segment 311 faces the surface to be cleaned.

[0067] See Figure 11 As shown, optionally, the first channel segment 311 forms an acute angle with the surface to be cleaned, and along a direction parallel to the surface to be cleaned, the distance from the end of the first channel segment 311 furthest from the surface to be cleaned to the first cleaning module 20 is greater than the distance from the end of the first channel segment 311 closest to the surface to be cleaned to the first cleaning module 20. By setting the first channel segment 311 to form an acute angle with the surface to be cleaned, and setting the distance from the end of the first channel segment 311 furthest from the surface to be cleaned to the first cleaning module 20 to be greater than the distance from the end of the first channel segment 311 closest to the surface to be cleaned to the first cleaning module 20, the first suction port 3111 can be closer to the first cleaning module 20, which is beneficial for the first suction port 3111 to more effectively remove the dirt stirred up by the first cleaning module 20 when the cleaning equipment retracts, thereby improving the suction efficiency during the retraction process.

[0068] It should be noted that the acute angle between the first channel segment 311 and the surface to be cleaned means that the extension direction of the first channel segment 311 and the surface to be cleaned are arranged at an acute angle; the distance from the end of the first channel segment 311 away from the surface to be cleaned to the first cleaning module 20 is greater than the distance from the end of the first channel segment 311 closer to the surface to be cleaned to the first cleaning module 20 in a direction parallel to the surface to be cleaned. This means that the first channel segment 311 is deflected towards the direction of the first cleaning module 20 from the end away from the surface to the end closer to the surface to be cleaned, so that the end of the first channel segment 311 closer to the surface to be cleaned is closer to the first cleaning module 20 than the end away from the surface to be cleaned.

[0069] See Figure 4 and Figure 6 As shown, optionally, the second channel segment 312 is perpendicular to the surface to be cleaned; by setting the second channel segment 312 to be perpendicular to the surface to be cleaned, the second suction port 3121 can face the surface to be cleaned in a direct manner, which is conducive to the vertical suction of dirt into the second channel segment 312, reducing the turning of the airflow path, thereby improving the suction efficiency of the second suction port 3121.

[0070] It should be noted that the second channel segment 312 being perpendicular to the surface to be cleaned means that the extension direction of the second channel segment 312 is perpendicular to the plane where the surface to be cleaned is located. That is, the second channel segment 312 extends along the normal direction of the surface to be cleaned, so that the second suction port 3121 formed at the end of the second channel segment 312 is facing the surface to be cleaned.

[0071] See Figure 11 As shown, optionally, the second channel segment 312 forms an acute angle with the surface to be cleaned, and along a direction parallel to the surface to be cleaned, the distance from the end of the second channel segment 312 furthest from the surface to be cleaned to the first cleaning module 20 is greater than the distance from the end of the second channel segment 312 closest to the surface to be cleaned to the first cleaning module 20. By setting the second channel segment 312 to form an acute angle with the surface to be cleaned, and setting the distance from the end of the second channel segment 312 furthest from the surface to be cleaned to the first cleaning module 20 to be greater than the distance from the end of the second channel segment 312 closest to the surface to be cleaned to the first cleaning module 20, the second suction port 3121 can be closer to the first cleaning module 20, which is beneficial for the second suction port 3121 to more effectively remove the dirt stirred up by the first cleaning module 20 when the cleaning equipment moves forward, thus improving the suction efficiency during the forward movement.

[0072] It should be noted that the acute angle between the second channel segment 312 and the surface to be cleaned means that the extension direction of the second channel segment 312 and the surface to be cleaned are arranged at an acute angle; the distance from the end of the second channel segment 312 away from the surface to be cleaned to the first cleaning module 20 is greater than the distance from the end of the second channel segment 312 closer to the surface to be cleaned to the first cleaning module 20 in a direction parallel to the surface to be cleaned. This means that the second channel segment 312 is deflected towards the direction of the first cleaning module 20 from the end away from the surface to the end closer to the surface to be cleaned, so that the end of the second channel segment 312 closer to the surface to be cleaned is closer to the first cleaning module 20 than the end away from the surface to be cleaned.

[0073] Optionally, the bottom surfaces of the first channel segment 311 and the second channel segment 312 are parallel to the surface to be cleaned. It should be noted that the bottom surface refers to the end face of the first channel segment 311 and the second channel segment 312 closest to the surface to be cleaned, i.e., the bottom plane where the first suction port 3111 and the second suction port 3121 are located; the bottom surface being parallel to the surface to be cleaned means that this end face is parallel to the surface to be cleaned, allowing the suction port to evenly contact the surface to be cleaned, avoiding scratches caused by tilting or unevenness at the edges of the suction port, and also facilitating a uniform suction distribution and improving suction efficiency.

[0074] See Figure 1 and Figure 2 As shown, optionally, the cleaning equipment also includes a direction detection module 100 and a moving wheel module 50. The direction detection module 100 is used to detect the movement direction of the cleaning equipment. The moving wheel module 50 is rotatably mounted on the equipment body 10, and the cleaning equipment moves on the surface to be cleaned via the moving wheel module 50. The direction detection module 100 detects the movement direction of the cleaning equipment by detecting the rotation direction of the moving wheel module 50. By setting the moving wheel module 50 and enabling the direction detection module 100 to determine the movement direction of the cleaning equipment by detecting the rotation direction of the moving wheel module 50, the direction detection module 100 can achieve direction recognition based on the movement state of the cleaning equipment itself, without relying on external sensors or manual operation by the user. This improves the accuracy and reliability of direction detection, providing a stable detection basis for the automatic switching of the opening and closing of the first suction port 3111 and the second suction port 3121. It should be noted that the moving wheel module 50 can be an active wheel for driving the movement of the cleaning equipment or a driven wheel for supporting the cleaning equipment.

[0075] It should be noted that the direction detection module 100 refers to the functional module in the cleaning equipment used to sense the direction of movement of the cleaning equipment. It can detect whether the cleaning equipment is in a forward or backward state and generate a corresponding detection signal. The moving wheel module 50 refers to a wheel-like structural component rotatably mounted on the main body 10 of the equipment to support the movement of the cleaning equipment on the surface to be cleaned. The moving wheel module 50 can rotate around its rotation axis under the action of external force, thereby driving the cleaning equipment forward or backward. The direction detection module 100 detects the direction of movement of the cleaning equipment by the rotation direction of the moving wheel module 50. The direction detection module 100 determines the moving direction of the cleaning equipment by sensing the rotation direction of the moving wheel module 50. For example, when the direction detection module 100 detects that the moving wheel module 50 rotates clockwise, it determines that the cleaning equipment is in a forward state; when it detects that the moving wheel module 50 rotates counterclockwise, it determines that the cleaning equipment is in a backward state. Alternatively, when the direction detection module 100 detects that the moving wheel module 50 rotates counterclockwise, it determines that the cleaning equipment is in a forward state; when it detects that the moving wheel module 50 rotates clockwise, it determines that the cleaning equipment is in a backward state.

[0076] Optionally, the direction detection module 100 includes an encoding unit 101 and a detection unit 102. The encoding unit 101 is disposed on the moving wheel module 50, and the detection unit 102 is disposed on the main body 10 of the device. The encoding unit 101 detects the rotation direction of the moving wheel module 50. By disposing the encoding unit 101 on the moving wheel module 50 and the detection unit 102 on the main body of the device, and by having the detection unit 102 indirectly detect the rotation direction of the moving wheel module by sensing the encoding unit 101 rotating with the wheel, non-contact and accurate identification of the movement direction of the cleaning equipment can be achieved, providing a stable and reliable detection basis for the automatic switching of the suction port.

[0077] It should be noted that the encoding unit 101 refers to a moving component disposed on the moving wheel module 50 for providing detectable physical characteristics, which can rotate synchronously with the moving wheel module 50; the detection unit 102 refers to a functional component fixedly disposed on the main body 10 of the device for sensing the motion state of the encoding unit 101; the encoding unit 101 being disposed on the moving wheel module 50 means that the encoding unit 101 is connected to the moving wheel module 50, so that the encoding unit 101 can rotate together with the moving wheel module 50. For example, the encoding unit 101 can be embedded inside the moving wheel module 50, attached to the surface of the moving wheel module 50, or integrally formed with the moving wheel module 50; the detection unit 102 detecting the rotation direction of the moving wheel module 50 through the encoding unit 101 means that when the moving wheel module 50 rotates, the encoding unit 101 rotates accordingly. The detection unit 102 determines the rotation direction of the moving wheel module 50 by sensing the movement of the encoding unit 101, for example, by detecting the alternating marks, grooves, or magnetic nodes on the encoding unit 101, thereby determining the movement direction of the cleaning device.

[0078] It is understood that the specific forms of the encoding unit 101 and the detection unit 102 include, but are not limited to: the encoding unit 101 being a code disk, the detection unit 102 being a photoelectric sensor, the code disk rotating synchronously with the moving wheel module 50, and the photoelectric sensor determining the rotation direction by detecting alternating through holes or reflective stripes on the code disk; or, the encoding unit 101 being a magnetic element, the detection unit 102 being a Hall sensor, the magnetic element rotating synchronously with the moving wheel module 50, and the Hall sensor determining the rotation direction by detecting changes in the magnetic field; or, the encoding unit 101 being a grating disk, the detection unit 102 being a photoelectric encoder, the grating disk rotating synchronously with the moving wheel module 50, and the photoelectric encoder outputting the rotation direction and angular displacement by reading the grating signal.

[0079] Optionally, the cleaning equipment also includes a control module, which is electrically connected to the direction detection module 100 and the first suction module 30. The control module is configured to control the opening and closing of the first suction port 3111 and the second suction port 3121 on the first suction module 30 according to the movement direction of the cleaning equipment detected by the direction detection module 100. By setting the control module, the cleaning equipment can automatically control the opening and closing of the first suction port 3111 and the second suction port 3121 according to the detection result of the direction detection module 100, eliminating the need for manual operation by the user according to the movement direction, thus improving the intelligence level of the cleaning equipment and the user experience.

[0080] It should be noted that the control module refers to the functional unit set on the main body 10 of the equipment, which is used to receive the detection signal of the direction detection module 100 and control the first suction module 30 to perform corresponding operations according to the preset logic. Its specific form includes, but is not limited to, microcontroller, single-chip microcomputer, etc. The electrical connection between the control module and the direction detection module 100 and the first suction module 30 means that the control module establishes a signal connection with the direction detection module 100 and the first suction module 30 via wired or wireless means to receive the detection signal sent by the direction detection module 100 and send control commands to the first suction module 30. The control module is configured to control the opening and closing of the first suction port 3111 and the second suction port 3121 on the first suction module 30 according to the moving direction of the cleaning equipment detected by the direction detection module 100. This means that the control module internally stores preset control logic: when the direction detection module 100 detects that the cleaning equipment is moving forward, the control module controls the first suction module 30 to stop sucking up dirt from the first suction port 3111; when the direction detection module 100 detects that the cleaning equipment is moving backward, the control module controls the first suction module 30 to stop sucking up dirt from the second suction port 3121.

[0081] Optionally, the control module is electrically connected to the first switch unit 33 and the second switch unit 34, and the control module is configured to control the first switch unit 33 and the second switch unit 34 according to the moving direction of the cleaning equipment detected by the direction detection module 100.

[0082] It should be noted that the electrical connection between the control module and the first switch unit 33 and the second switch unit 34 refers to the control module establishing a signal connection with the first switch unit 33 and the second switch unit 34 via wired or wireless means to send control commands to the first switch unit 33 and the second switch unit 34. The control module is configured to control the first switch unit 33 and the second switch unit 34 according to the direction of movement of the cleaning equipment detected by the direction detection module 100. This means that the control module internally stores preset control logic: when the direction detection module 100 detects that the cleaning equipment is moving forward, the control module controls the first switch unit 33 to close, blocking the first channel segment 311, and simultaneously controls the second switch unit 34 to open, thus connecting the second channel segment 312; when the direction detection module 100 detects that the cleaning equipment is moving backward, the control module controls the second switch unit 34 to close, blocking the second channel segment 312, and simultaneously controls the first switch unit 33 to open, thus connecting the first channel segment 311.

[0083] Optionally, the control module is electrically connected to the switching unit 32, and the control module is configured to control the switching unit 32 to switch between a first state and a second state based on the direction of movement of the cleaning equipment detected by the direction detection module 100.

[0084] It should be noted that the electrical connection between the control module and the switching unit 32 refers to the control module establishing a signal connection with the switching unit 32 via wired or wireless means to send control commands to the switching unit 32; the control module is configured to control the switching unit 32 to switch between a first state and a second state based on the direction of movement of the cleaning equipment detected by the direction detection module 100. This means that the control module internally stores preset control logic: when the direction detection module 100 detects that the cleaning equipment is moving forward, the control module controls the switching unit 32 to switch to the second state to open the second channel segment 312 and close the first channel segment 311; when the direction detection module 100 detects that the cleaning equipment is moving backward, the control module controls the switching unit 32 to switch to the first state to open the first channel segment 311 and close the second channel segment 312.

[0085] See Figures 3 to 6 As shown, optionally, the first cleaning module 20 includes a first roller brush unit 21, which is rotatably disposed on the main body 10 of the device. The first roller brush unit 21 rotates along a first direction when the cleaning device moves forward and backward. By setting the first roller brush unit 21 to rotate along the same direction when moving forward and backward, it is beneficial to simplify the drive control logic of the first roller brush unit 21, so that the cleaning device does not need to switch the rotation direction of the first roller brush unit 21 according to its movement direction.

[0086] It should be noted that the first roller brush unit 21 refers to a rotatable component disposed on the main body 10 of the equipment, used to contact the surface to be cleaned to agitate dirt, and can rotate around its own axis under the drive of the drive device; the first roller brush unit 21 is rotatably disposed on the main body 10 of the equipment, meaning that the first roller brush unit 21 is installed on the main body 10 of the equipment via a rotating shaft or bearing, so that it can rotate freely relative to the main body 10 of the equipment; the first roller brush unit 21 rotates in the first direction when the cleaning equipment moves forward and backward, meaning that no matter whether the cleaning equipment is in the forward or backward state, the first roller brush unit 21 always maintains the same rotation direction and does not change its rotation direction due to the change in the movement direction of the cleaning equipment.

[0087] Optionally, the first roller brush unit 21 rotates in a first direction when the cleaning device moves forward and in a second direction when the cleaning device moves backward, wherein the first direction and the second direction are opposite. By setting the first roller brush unit 21 to rotate in opposite directions when the cleaning device moves forward and backward, the first roller brush unit 21 can always rotate in a manner that facilitates throwing dirt towards the working suction port, thereby improving the dirt suction efficiency of the cleaning device. Specifically, when the cleaning device moves forward, the second suction port 3121 is in the open state, and the first roller brush unit 21 rotates in the first direction to throw the stirred dirt backward to the second suction port 3121; when the cleaning device moves backward, the first suction port 3111 is in the open state, and the first roller brush unit 21 rotates in the second direction to throw the stirred dirt forward to the first suction port 3111, thereby improving the dirt suction efficiency in the bidirectional cleaning process.

[0088] It should be noted that the first roller brush unit 21 rotates in a first direction when the cleaning device moves forward and rotates in a second direction when the cleaning device moves backward. The first direction and the second direction are opposite, meaning that the rotation direction of the first roller brush unit 21 is related to the movement direction of the cleaning device: when the cleaning device moves forward, the first roller brush unit 21 rotates in the first direction; when the cleaning device moves backward, the first roller brush unit 21 switches to rotating in the second direction, which is opposite to the first direction.

[0089] Optionally, the first direction refers to the direction in which the first roller brush unit 21 can throw the stirred-up dirt backward to the second suction port 3121. Of course, the first direction can also be other directions.

[0090] Optionally, the first roller brush unit 21 rotates at the same speed when the cleaning device moves forward and backward. By setting the first roller brush unit 21 to rotate at the same speed when moving forward and backward, it is beneficial to simplify the drive control logic of the first roller brush unit 21, so that the cleaning device does not need to change the rotation speed of the first roller brush unit 21 according to its direction of movement.

[0091] It should be noted that the first roller brush unit 21 maintains the same rotation speed when the cleaning equipment moves forward and backward. This means that the first roller brush unit 21 always maintains the same rotation speed regardless of whether the cleaning equipment is in a forward or backward state, and the rotation speed is not adjusted due to changes in the direction of movement of the cleaning equipment.

[0092] Optionally, the first roller brush unit 21 rotates at a first rotational speed when the cleaning device moves forward and at a second rotational speed when the cleaning device moves backward, wherein the first rotational speed is greater than the second rotational speed. By setting the first roller brush unit 21 to rotate at a higher rotational speed when the cleaning device moves forward and at a lower rotational speed when it moves backward, a stronger agitation effect can be provided at a higher rotational speed during the forward movement, improving the efficiency of dirt lifting, and achieving efficient dirt suction in conjunction with the second suction port 3121 opened at the rear; while during the backward movement, since the backward movement is usually used to supplement the suction of the cleaned area or adjust its position, the lower rotational speed is sufficient to meet the cleaning needs, and at the same time, it can also reduce the energy consumption and noise of the cleaning device to a certain extent. Furthermore, when the first roller brush unit 21 rotates in the first direction when the cleaning device moves forward and backward, having the first rotational speed greater than the second rotational speed also helps to reduce the backward resistance of the cleaning device and improve the user experience.

[0093] It should be noted that the first roller brush unit 21 rotates at a first speed when the cleaning device moves forward and at a second speed when the cleaning device moves backward. The first speed being greater than the second speed means that the rotational speed of the first roller brush unit 21 is related to the direction of movement of the cleaning device: when the cleaning device moves forward, the first roller brush unit 21 rotates at a higher first speed; when the cleaning device moves backward, the first roller brush unit 21 rotates at a lower second speed, and the first speed is greater than the second speed.

[0094] Optionally, the first cleaning module 20 further includes a first roller brush drive unit, which is disposed on the main body 10 and drivenly connected to the first roller brush unit 21 for driving the first roller brush unit 21 to rotate. The specific form of the first roller brush drive unit includes, but is not limited to, an electric motor, a pneumatic motor, and a hydraulic motor.

[0095] Optionally, the control module is electrically connected to the first roller brush drive unit, and the control module is configured to control the first roller brush drive unit according to the moving direction of the cleaning equipment detected by the direction detection module 100.

[0096] It should be noted that the electrical connection between the control module and the first roller brush drive unit means that the control module establishes a signal connection with the first roller brush drive unit via wired or wireless means to send control commands to the first roller brush drive unit; the control module is configured to control the first roller brush drive unit according to the direction of movement of the cleaning equipment detected by the direction detection module 100, which means that the control module has preset control logic stored inside.

[0097] For example: when the direction detection module 100 detects that the cleaning device is moving forward, the control module controls the first roller brush drive unit to drive the first roller brush unit 21 to rotate in a first direction; when the direction detection module 100 detects that the cleaning device is moving backward, the control module controls the first roller brush drive unit to drive the first roller brush unit 21 to rotate in a second direction opposite to the first direction; or, when the direction detection module 100 detects that the cleaning device is moving forward, the control module controls the first roller brush drive unit to drive the first roller brush unit 21 to rotate at a first speed; when the direction detection module 100 detects that the cleaning device is moving backward, the control module controls the first roller brush drive unit to drive the first roller brush unit 21 to rotate at a second speed.

[0098] See Figure 12 and Figure 14 As shown, optionally, the cleaning device further includes a second cleaning module 60 and a second suction module 70, both of which are disposed on the main body 10 of the device. The orthographic projection of the first suction module 30 on the reference plane and the orthographic projection of the second suction module 70 on the reference plane at least partially overlap, wherein the reference plane is parallel to the forward direction of the cleaning device and perpendicular to the surface to be cleaned. By setting the orthographic projections of the first suction module 30 and the second suction module 70 to at least partially overlap on the reference plane, the space occupied by the two suction modules in the height direction of the cleaning device can at least partially overlap, which is beneficial to the compact layout of the internal structure of the cleaning device and realizes the miniaturization design of the cleaning device.

[0099] It should be noted that the second cleaning module 60 refers to another functional module installed on the main body 10 of the equipment for contacting the surface to be cleaned to agitate or scrub the dirt; the second suction module 70 refers to another functional module installed on the main body 10 of the equipment for guiding dirt into the cleaning equipment for recycling; the orthographic projection of the first suction module 30 on the reference plane and the orthographic projection of the second suction module 70 on the reference plane at least partially overlap means that the first suction module 30 and the second suction module 70 are projected onto the reference plane in a direction perpendicular to the reference plane, and the two projections have at least a partially overlapping area on the reference plane.

[0100] See Figure 12 As shown, optionally, the cleaning equipment also includes a second negative pressure module 80, which is disposed on the main body 10 of the equipment. The second suction module 70 has a third suction port 711, which corresponds to the position of the second cleaning module 60. The first negative pressure module 40, the waste recovery module 90, and the first suction module 30 are connected in sequence, as are the second negative pressure module 80, the waste recovery module 90, and the second suction module 70. By setting up the waste recovery module 90, the sucked-in waste can be collected in a concentrated manner, preventing waste from directly entering the second negative pressure module 80 and causing pollution or damage. It also facilitates user cleaning and maintenance.

[0101] It should be noted that the second negative pressure module 80 refers to another functional module installed on the main body 10 of the equipment, used to generate negative pressure to provide suction power. The specific form of the second negative pressure module 80 includes, but is not limited to, a fan or a vacuum pump, used to provide suction power for the second suction module 70. The second negative pressure module 80, the waste recovery module 90 and the second suction module 70 are connected in sequence, meaning that the second negative pressure module 80, the waste recovery module 90 and the second suction module 70 are connected in series through a fluid channel, so that the suction force generated by the second negative pressure module 80 can act on the second suction module 70 through the waste recovery module 90, thereby sucking the waste from the third suction port 711 of the second suction module 70 and collecting it into the waste recovery module 90.

[0102] It is understandable that the waste recovery module 90 is sequentially connected to the second negative pressure module 80 and the second waste suction module 70 to form a complete waste suction circuit: the second negative pressure module 80 generates negative pressure, which is transmitted to the second waste suction module 70 through the waste recovery module 90, so that the waste is sucked into the second waste suction module 70 with the airflow and then enters the waste recovery module 90. The waste is trapped in the waste recovery module 90, while the airflow continues to flow to the second negative pressure module 80 and is then discharged.

[0103] Optionally, the first cleaning module 20 is a liquid dirt cleaning module, with the positions of the first suction port 3111 and the second suction port 3121 corresponding to the position of the first cleaning module 20. The second cleaning module 60 is a solid dirt cleaning module, with the position of the third suction port 711 corresponding to the position of the second cleaning module 60. In the forward direction of the cleaning equipment, the second cleaning module 60 is located in front of the first cleaning module 20, and the third suction port 711 is located in front of the first suction port 3111. By placing the second cleaning module 60 in front of the first cleaning module 20 and placing the third suction port 711 in front of the first suction port 3111, the cleaning equipment can first process solid dirt through the solid dirt cleaning module and suck it in through the front-side third suction port 711, then process liquid dirt through the liquid dirt cleaning module and suck it in through the rear-side second suction port 3121. This achieves separate and sequential cleaning of solid and liquid dirt, avoiding cross-contamination and improving the cleaning effect. The second suction module 70 and the first suction module 30 can be installed separately or integrated into a single structure. For a cleaning device where the second suction module 70 and the first suction module 30 are integrated into a single structure, see [reference needed]. Figure 13 As shown.

[0104] It should be noted that the liquid dirt cleaning module refers to a functional component installed on the main body 10 for contacting the surface to be cleaned to handle liquid dirt (such as sewage, liquid stains, etc.); the solid dirt cleaning module refers to a functional component installed on the main body 10 for contacting the surface to be cleaned to handle solid dirt (such as dust, particles, debris, etc.); the positions of the first suction port 3111 and the second suction port 3121 correspond to the positions of the first cleaning module 20, meaning that the first suction port 3111 and the second suction port 3121 are respectively located on the front and rear sides of the first cleaning module 20, for sucking up the liquid dirt processed by the first cleaning module 20. The position of the third suction port 711 corresponding to the position of the second cleaning module 60 means that the third suction port 711 is set on the front or rear side of the second cleaning module 60, and is used to remove solid dirt processed by the second cleaning module 60; in the forward direction of the cleaning equipment, the second cleaning module 60 being located in front of the first cleaning module 20 means that along the moving direction of the cleaning equipment during normal cleaning operation, the second cleaning module 60 is located in front of the first cleaning module 20; the third suction port 711 being located in front of the first suction port 3111 means that along the forward direction of the cleaning equipment, the third suction port 711 is located in front of the first suction port 3111.

[0105] Optionally, the first channel segment 311, the second channel segment 312, and the third channel segment 313 constitute at least a portion of the first waste recovery channel. The second waste suction module 70 has a fourth channel segment 71 communicating with the external environment, and a third waste suction port 711 is formed in the fourth channel segment 71. The fourth channel segment 71 constitutes at least a portion of the second waste recovery channel, which is independent of the first waste recovery channel. The fourth channel segment 71 refers to a tubular or channel-like structure in the second waste suction module 70 that is fluidly communicating with the external environment, and the third waste suction port 711... The third suction port 711 is formed at the opening of the fourth channel segment 71 that connects to the external environment. The opening of the fourth channel segment 71 that connects to the external environment refers to the end of the fourth channel segment 71, that is, the end of the fourth channel segment 71 near the second cleaning module 60, which is naturally formed and connects to the external environment. The first waste recovery channel is fluidly connected to the waste recovery module 90 and the first suction port 3111 and the second suction port 3121. The second waste recovery channel is fluidly connected to the waste recovery module 90 and the third suction port 711.

[0106] Understandably, when the first cleaning module 20 is a liquid waste cleaning module and the second cleaning module 60 is a solid waste cleaning module, the cross-sectional area of ​​the second waste collection channel is larger than that of the first waste collection channel. Since solid waste (such as dust, particles, and debris) has a larger volume and poorer flowability compared to liquid waste (such as sewage and liquid stains), a relatively larger cross-sectional area of ​​the second waste collection channel ensures smooth waste transport and prevents channel blockage. Liquid waste, on the other hand, has good flowability, so a relatively smaller cross-sectional area of ​​the first waste collection channel is sufficient to meet transport requirements and helps maintain flow rate.

[0107] Optionally, the first cleaning module 20 is a liquid dirt cleaning module. The first cleaning module 20 also includes a cleaning fluid supply unit 22, which is used to directly or indirectly supply cleaning fluid to the first roller brush unit 21. It should be noted that the cleaning fluid supply unit 22 refers to a functional component installed on the main body 10 for storing and transporting cleaning fluid. It includes a storage tank, a pumping assembly, a supply pipeline, and a liquid distribution component. The cleaning fluid supply unit 22 directly or indirectly supplies cleaning fluid to the first roller brush unit 21, meaning that the cleaning fluid supply unit 22 can directly supply cleaning fluid to the first roller brush unit 21 by spraying cleaning fluid onto the first roller brush unit 21, or indirectly supply cleaning fluid to the first roller brush unit 21 by spraying cleaning fluid onto the area to be cleaned corresponding to the first roller brush unit 21, in order to assist the cleaning process.

[0108] Understandably, when the cleaning equipment moves forward, stopping the first suction port 3111 from sucking in dirt can prevent the cleaning liquid on the front side of the first roller brush unit 21 from being directly sucked away by the first suction port 3111. When the cleaning equipment moves backward, stopping the second suction port 3121 from sucking in dirt can prevent the cleaning liquid on the rear side of the first roller brush unit 21 from being directly sucked away by the second suction port 3121, thereby ensuring that the cleaning liquid can effectively act on the surface to be cleaned.

[0109] Optionally, the first negative pressure module 40 operates at the same power when the cleaning equipment moves forward and backward. By setting the first negative pressure module 40 to operate at the same power when moving forward and backward, it is beneficial to simplify the drive control logic of the first negative pressure module 40, so that the cleaning equipment does not need to change the operating power of the first negative pressure module 40 according to its direction of movement.

[0110] It should be noted that the operating power of the first negative pressure module 40 remains unchanged when the cleaning equipment moves forward and backward. This means that the first negative pressure module 40 always maintains the same operating power regardless of whether the cleaning equipment is in a forward or backward state, and the operating power is not adjusted due to the change of the moving direction of the cleaning equipment.

[0111] Optionally, the first negative pressure module 40 operates at a first power when the cleaning equipment moves forward and at a second power when the cleaning equipment moves backward, wherein the first power is greater than the second power. By setting the first negative pressure module 40 to operate at a higher power when the cleaning equipment moves forward and at a lower power when it moves backward, a stronger suction effect can be provided with higher power during the forward movement, improving the efficiency of dirt recovery; while during the backward movement, since the backward movement is usually used to supplement the suction of the already cleaned area or adjust its position, the lower power is sufficient to meet the suction needs, and at the same time, it can also reduce the energy consumption and noise of the cleaning equipment to a certain extent.

[0112] It should be noted that the first negative pressure module 40 operates at a first power when the cleaning equipment moves forward and at a second power when the cleaning equipment moves backward. The first power being greater than the second power means that the operating power of the first negative pressure module 40 is related to the direction of movement of the cleaning equipment: when the cleaning equipment moves forward, the first negative pressure module 40 operates at a higher first power; when the cleaning equipment moves backward, the first negative pressure module 40 operates at a lower second power, and the first power is greater than the second power.

[0113] Optionally, the control module is electrically connected to the first negative pressure module 40, and the control module is configured to control the first negative pressure module 40 according to the moving direction of the cleaning equipment detected by the direction detection module 100.

[0114] It should be noted that the electrical connection between the control module and the first negative pressure module 40 refers to the control module establishing a signal connection with the first negative pressure module 40 via wired or wireless means to send control commands to the first negative pressure module 40; the control module being configured to control the first negative pressure module 40 according to the direction of movement of the cleaning equipment detected by the direction detection module 100 means that the control module internally stores preset control logic. For example, when the direction detection module 100 detects that the cleaning equipment is moving forward, the control module controls the first negative pressure module 40 to operate at a higher first power to provide a stronger suction effect; when the direction detection module 100 detects that the cleaning equipment is moving backward, the control module controls the first negative pressure module 40 to operate at a lower second power to reduce energy consumption and noise; or, the control module controls the first negative pressure module 40 to operate at the same power when moving forward and backward to simplify the control logic.

[0115] See Figure 15 As shown, according to another aspect of this application, a cleaning system 3000 is provided. The cleaning system 3000 includes a cleaning device 1000 and a base station 2000. The cleaning device 1000 can be placed on the base station 2000. The cleaning device 1000 is the cleaning device 1000 described above.

[0116] It should be noted that the base station 2000 refers to a supporting device set up in a specific location to provide at least one logistical support function for the cleaning equipment 1000. Its functions include, but are not limited to: providing a charging interface for the cleaning equipment 1000 to achieve energy replenishment; storing and supplying cleaning liquid or clean water to the cleaning equipment 1000; receiving the dirt collected by the cleaning equipment 1000; cleaning, drying or disinfecting the first cleaning module 20 and the second cleaning module 60 on the cleaning equipment 1000; and interacting with the cleaning equipment 1000 for task data, status information or control commands.

[0117] In summary, implementing the aforementioned cleaning equipment and system has at least the following beneficial technical effects: The cleaning equipment, by providing a first suction port 3111 and a second suction port 3121 on the front and rear sides of the first cleaning module 20 respectively, and by configuring the first suction port 3111 to stop sucking up dirt from the surface to be cleaned when the cleaning equipment moves forward, and configuring the second suction port 3121 to stop sucking up dirt from the surface to be cleaned when the cleaning equipment moves backward, allows the cleaning equipment to control the suction of dirt from the first suction port 3111 and the second suction port 3121 according to its direction of movement. Specifically, when the cleaning equipment moves forward, since the first suction port 3111 stops sucking up dirt from the surface to be cleaned, the first cleaning module 20 first contacts the surface to be cleaned to agitate the dirt. The cleaning liquid supply unit 22 outputs cleaning liquid to mix with the dirt, and then the second suction port 3121 sucks up the agitated mixture, avoiding the first suction port 3111 stopping sucking up dirt from the surface to be cleaned. The first suction port 3111 draws in the cleaning fluid just output from the cleaning fluid supply unit 22, thus avoiding interference from the first suction port 3111 on the forward cleaning process. When the cleaning device moves backward, since the second suction port 3121 stops sucking in dirt from the surface to be cleaned, the first cleaning module 20 first contacts the surface to be cleaned to agitate the dirt. The cleaning fluid output from the cleaning fluid supply unit 22 mixes with the dirt, and then the first suction port 3111 draws in the agitated mixture. This avoids the second suction port 3121 drawing in the cleaning fluid just output from the cleaning fluid supply unit 22, and also avoids interference from the second suction port 3121 on the backward cleaning process. Compared with existing cleaning devices that only consider the suction effect in one direction, the cleaning device of this application can achieve a better suction effect in both forward and backward bidirectional movement, thereby effectively improving the consistency of the cleaning ability of the cleaning device in different directions and improving the user experience.

[0118] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
