Description

Technical Field

[0001] This invention relates to the field of floor cleaning, and more specifically to a cleaning machine and its control method. Background Technology

[0002] Existing cleaning machines mainly perform mopping or washing functions on the ground. They are mainly equipped with rollers, a clean water tank, and a wastewater tank. The rollers are used to contact the ground for cleaning. The clean water tank is mainly used to provide clean water to the rollers. Wastewater is generated when there is clean water and during the cleaning process. The wastewater is collected in the wastewater tank so that users can maintain the wastewater tank and prevent the wastewater from causing secondary pollution to the ground.

[0003] In the process of collecting sewage in the sewage tank, existing technologies generally use a fan with airflow suction to draw the sewage into the tank. For handheld cleaning machines, the sewage tank is usually mounted on a push rod, which the user uses to move the machine on the ground. However, when the user rotates and tilts the push rod to clean low spaces such as under tables, beds, or sofas, the push rod needs to be tilted at a large angle to meet the user's cleaning needs. When the push rod is tilted at a large angle, the sewage in the tank also tilts, which can easily cause sewage to flow back into the fan, damaging the fan and seriously affecting the safety of the cleaning machine. At the same time, existing technologies cannot effectively detect the sewage in the tank in a timely manner to prevent sewage from flowing back into the fan, resulting in low overall reliability and safety of the cleaning machine. Summary of the Invention

[0025] In the aforementioned cleaning machine, when the push rod body is tilted relative to the ground drag body and the sewage chamber is filled with sewage, the height H3 from the bottom position of the airflow port to the sewage surface and / or the height H4 from the position where the touch sensor intersects with the surface of the sewage chamber to the sewage surface is greater than the height H5 from the position where the top of the sewage chamber intersects with the rear side of the sewage chamber to the sewage surface.

[0027] The aforementioned cleaning machine has two touch-sensitive components that extend towards the wastewater chamber.

[0028] The two tactile components are arranged in a spaced-out structure along the front-back direction of the sewage chamber. When the sewage chamber is filled with sewage, the height from the bottom of the tactile component on the front side to the sewage surface is greater than or equal to the height from the bottom of the tactile component on the rear side to the sewage surface.

[0029] Alternatively, the two tactile sensors can be arranged in a spaced-out configuration along the left-right direction of the sewage chamber, and when the sewage chamber is filled with sewage, the bottom positions of the two tactile sensors are at the same height as the sewage surface.

The sewage inlet is configured to be connected to the sewage chamber in the direction of the sewage chamber.

[0031] The sewage inlet is located behind the airflow inlet, or in the area between the central axis W1 along the length of the push rod body on the sewage tank and the rear part of the sewage tank.

[0032] The aforementioned cleaning machine has a roller on its main body for contacting the ground to clean;

[0033] The drum is designed to be connected to the inlet through the sewage inlet channel, and a filter device is installed between the drum and the sewage inlet channel to form a structure in which the sewage on the drum is filtered and then enters the sewage inlet channel.

[0034] Alternatively, a wastewater zone can be set on one side of the drum to collect wastewater on the drum, and the drum can be connected to the inlet through the wastewater zone. A filtration device is installed in the wastewater zone so that the wastewater on the drum is filtered before entering the inlet.

[0035] The aforementioned cleaning machine has a chamber-dividing component at the upper part of the sewage chamber, and a ring-shaped sealing component at the upper part of the chamber-dividing component. The chamber-dividing component has an airflow chamber and a sewage inlet chamber, and the airflow chamber and the sewage inlet chamber are set as independent cavity structures. The airflow chamber is connected to the airflow port, and the sewage inlet chamber is connected to the sewage inlet.

[0036] The aforementioned cleaning machine has an airflow interface on the push rod body. The airflow interface is configured to be open towards the side or top of the push rod body, and the corresponding airflow interface is configured to be through towards the side or top of the push rod body to form a structure that is connected to the airflow cavity.

[0037] The aforementioned cleaning machine has a sewage inlet on the push rod body. The sewage inlet is designed to be open towards the side or top of the push rod body, and the sewage inlet is also designed to be through towards the side or top of the push rod body to form a structure that is connected to the sewage inlet chamber.

[0038] The sewage inlet is also designed to be connected to the roller installed on the main body of the mop.

[0039] The aforementioned cleaning machine has a sewage discharge channel inside the sewage chamber. The end of the sewage discharge channel is located near the bottom of the sewage chamber. The sewage discharge channel extends upward toward the sewage chamber and passes through the top or side surface of the sewage tank to form a sewage outlet.

[0040] The push rod body is also provided with a sewage outlet, which is open to the side or bottom of the push rod body to form a structure that is connected to the outside of the push rod body.

[0041] Furthermore, a sewage channel is provided between the sewage outlet and the sewage discharge outlet, and a sewage discharge module is installed on the sewage channel.

[0042] The aforementioned cleaning machine includes a sewage discharge module comprising an actuating element and a sewage discharge element. The actuating element is located outside the sewage discharge element and is a movable structure. The sewage discharge element has a sewage discharge channel. When the actuating element moves to press against the sewage discharge element, it forms a structure in which the actuating element does not contact the sewage discharge channel or the sewage in the sewage discharge channel, and forms a structure that seals and closes the sewage discharge channel.

[0043] The aforementioned cleaning machine also includes a flow-blocking component inside the sewage chamber. The flow-blocking component has a flow-restricting part, which at least constitutes a shielding structure for a portion of the cross-section of the sewage chamber to block sewage. The flow-restricting part is located in the area above the middle of the length direction of the sewage chamber.

[0044] The aforementioned cleaning machine has a sewage discharge channel installed on a flow-blocking component, and the flow-blocking component is also equipped with a rotatable swing component. At least the position corresponding to the end of the sewage discharge channel is installed on the swing component so that the swing component can drive the position corresponding to the end of the sewage discharge channel to swing up and down in the vertical direction.

A first energy replenishment module is installed inside the installation cavity, and a corresponding second energy replenishment module is installed on the sewage tank. When the sewage tank is installed in place, the first energy replenishment module and the second energy replenishment module are connected to form a structure that can replenish energy.

[0046] The control method for the cleaning machine includes the cleaning machine as described above, and the cleaning machine also includes a control unit and an airflow device, which is directly or indirectly connected to the airflow port.

[0047] The control unit is electrically connected to the tactile module and the airflow device, respectively;

[0048] It also includes the following control methods:

[0049] Step S1: The control unit detects the time value T of continuous contact between the tactile sensor and the sewage in the sewage chamber, where T is a non-empty value, and compares the time value T with the preset time threshold T0 in the control unit;

[0050] Step S2: If the detected time value T is less than the time threshold T0, control the airflow to stop working and the stop time is T1, where T1 is less than or equal to 30 or 60 seconds. Then control the airflow to restart working and proceed to step S1.

[0051] Step S2': If the detected time value T is greater than or equal to the time threshold T0, control the airflow device to stop working and indicate that the sewage is full.

[0052] The aforementioned control method for the cleaning machine sets T0 to be greater than or equal to 10 seconds, or sets T1 to be greater than or equal to 5 seconds, or sets T1 to be greater than or equal to 5 seconds and less than T0.

[0053] The control method for the cleaning machine includes the cleaning machine as described above, and the cleaning machine also includes a control unit, a water supply mechanism and an airflow device, the airflow device being directly or indirectly connected to the airflow port;

[0054] The control unit is electrically connected to the touch module, the water supply mechanism, and the airflow device, respectively.

[0055] The control unit controls the airflow device to start operation and enters the following control mode:

[0056] Step S01: Control the water supply mechanism to start working;

[0057] Step S02: The control unit is set with a detection cycle of time value t, where time value t is greater than or equal to 2 seconds;

[0058] If the tactile sensor is detected to be in contact with sewage in the sewage chamber during a single detection cycle, the water supply mechanism will be controlled to stop working during that detection cycle.

[0059] Furthermore, if the time t1 during which the tactile sensor is in continuous contact with the sewage in the sewage chamber is greater than or equal to the preset time threshold t0 in the control unit within a single detection cycle, it indicates that the sewage chamber is full.

[0060] Furthermore, if the cumulative contact time t2 between the tactile sensor and the sewage in the sewage chamber is greater than or equal to 0.5 times the time t within a single detection cycle, it indicates that the sewage chamber is full.

[0061] The aforementioned control method for the cleaning machine also includes step S03: if no indication of full sewage is given in step S02, proceed to step S01.

[0062] Compared with the prior art, the present invention has the following beneficial effects:

[0063] In this solution, by setting the position limits of the airflow port and the touch module, and combining the position limit when the push rod body is tilted, it is ensured that the touch module can effectively detect the liquid level of the sewage in advance. This can effectively prevent sewage from flooding the airflow port when the sewage tank is tilted, or even sewage from entering the airflow port and entering the airflow device, causing damage to the airflow device. This solution provides safety and reliability for the cleaning machine to suck up sewage.

[0064] This solution uses a touch-sensing module to detect and judge the liquid level of sewage. Combined with the tilt angle of the push rod body, the positional relationship between the touch-sensing module and the airflow port and the limiting structure are set to enable the touch-sensing module to reliably detect in advance whether the liquid level of sewage will cause the airflow port to be submerged. This allows for advance control of the airflow device's working state, preventing sewage from submerging the airflow port, improving the overall stability and safety of the cleaning machine, and enhancing the reliability of the sewage tank in collecting sewage.

[0065] This solution primarily positions the touch module behind the airflow inlet, along the tilt direction of the push rod body. This ensures that when the push rod body is tilted, the distance between the airflow inlet and the sewage surface is large, while the distance between the touch module and the sewage surface is small. Combined with the positional distribution limitation, the touch module can pre-detect the liquid level, preventing sewage from flooding the airflow inlet and ensuring that sewage does not enter the airflow inlet, so that the cleaning machine can safely suck up and collect the sewage.

[0066] The structure of this design allows the airflow device to stably suck up sewage from the drum. At the same time, the structural design of the airflow device and the sewage chamber, such as the airflow interface and airflow chamber, further prevents sewage from entering the airflow device, forming a multi-layer protection effect for the airflow device. Even if sewage splashes into the airflow port due to accident, it will not enter the airflow device, further improving the safety and stability of the airflow device's operation.

[0067] The structure of this solution allows for a stable supply of airflow to draw in wastewater, while also ensuring that wastewater is collected within the wastewater chamber and discharged outwards. This improves the ease of maintenance for the wastewater tank and enhances the user experience.

[0068] In this design, structures such as the partitioned chambers enable separate chambers for wastewater collection and airflow supply, preventing airflow dispersion and wastewater dispersion during collection. This ensures stable airflow for collecting wastewater into the wastewater tank and prevents wastewater from being easily drawn into the airflow inlet due to dispersion.

[0069] In this solution, a sewage discharge module is set up to discharge sewage from the sewage tank. The sewage discharge module can achieve stable and effective sewage discharge, and it is not easy to cause blockage during the sewage discharge process. At the same time, when the sewage discharge is turned off, it is not easy to cause air leakage, which makes the cleaning machine more stable and reliable.

[0070] The overall structure of the sewage discharge module is simple. The opening and closing effect of the sewage discharge component is achieved by setting a sewage discharge component and a trigger component. At the same time, the trigger component does not come into contact with sewage, so the sewage discharge component can be used independently for the passage of sewage. Since the trigger component does not come into contact with sewage, it is not easy for sewage or garbage to get stuck. It is also not easy for the sewage to cause blockage problems and reduced reliability due to the squeezing of garbage.

[0071] The actuator in this design can stably press against the sewage discharge component to achieve a closing effect, and not press against it to achieve an opening effect. The actuator is located on the outside and can independently open and close the sewage discharge component, allowing sewage to flow independently within the sewage discharge component without causing pollution to the actuator. This helps the sewage discharge component maintain a good overall channel flow effect, improving the sewage discharge capacity and reliability.

[0072] The structure of the actuator and the drain component in this solution can achieve a stable opening and closing effect. At the same time, during the process of the actuator pressing the drain component, it can effectively push away the garbage in the sewage, so that the actuator can stably press the drain component to form a closure, and it is not easy to have problems with air leakage.

[0073] The overall structure of the sewage tank in this solution can prevent sewage accumulation, especially preventing sewage from sloshing or accumulating and flowing to the airflow port when the push rod body is tilted. Anti-flow components are installed in the sewage chamber to block the sewage, effectively preventing sewage from accumulating at the airflow port and preventing sewage from flooding the airflow port and damaging the airflow device.

[0074] The cleaning machine in this solution has a simple overall structure and is safer and more reliable in collecting and absorbing sewage. It can effectively collect sewage and prevent sewage from entering the airflow unit. Attached Figure Description

Detailed Implementation

[0086] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific embodiments.

[0087] Example: The cleaning machine and its control method of the present invention, such as Figures 1 to 10 As shown in the diagram, the cleaning machine 1 is mainly used to move on the ground to clean the ground. It can perform mopping and washing cleaning. At the same time, it promptly disposes of the wastewater generated during the cleaning process to prevent secondary pollution of the ground and facilitates wastewater maintenance and treatment for users.

[0088] The cleaning machine 1 of this solution includes a push rod body 10 and a mop body 11. The push rod body 10 is rotatably mounted on the mop body 11. The push rod body 10 is positioned so that its tilted structure relative to the mop body 11 faces backward, and the opposite direction is forward. The user can hold the push rod body 10 to move the mop body 11 on the ground to clean the floor. The user's ability to rotate the push rod body 10 relative to the mop body 11 is suitable for cleaning indoor floors, such as the underside of tables or sofas, which are relatively low areas. The spatial area corresponds to the ground position to better meet the user's needs. The push rod body 10 rotates relative to the mop body 11 to form an inclined structure with the rear direction and the opposite direction being the front direction. That is, the user can rotate the push rod body 10 to hold and push the cleaning machine 1 forward in the front direction, and the opposite direction is the rear direction. By rotating the push rod body 10 in the rear direction, the user can easily drive the mop body 11 to move in the front direction on the ground to achieve the cleaning effect.

[0089] Specifically, a sewage tank 101 is installed on the push rod body 10. The sewage tank 101 is used to hold and collect sewage. A sewage chamber 1011 is provided inside the sewage tank 1011. A touch-sensing module 1012 is provided on the upper part of the sewage chamber 1011. The touch-sensing module 1012 is used to detect the contact with the sewage in the sewage chamber 1011, mainly detecting the sewage level in the sewage chamber 1011. At the same time, an airflow port 10111 is provided on the upper part of the sewage chamber 1011. The airflow port 10111 is mainly used to generate airflow suction in the sewage chamber 1011 to collect sewage into the sewage chamber 1011. The airflow port 10111 can be connected to an airflow device 13, which mainly generates airflow suction to achieve sewage suction and collection. The touch-sensing module 1012 in this solution can effectively detect sewage to prevent sewage from flooding the airflow port 10111 or entering the airflow port 10111 and causing problems. The wastewater damage cleaning machine 1 includes a touch module 1012 that includes at least a touch element 10121. At least a portion of the touch element 10121 is located within the wastewater chamber 1011 such that when the push rod body 10 rotates relative to the drag body 11 to form an inclination angle A and the distance from the surface of the wastewater in the wastewater chamber 1011 to the bottom of the airflow port 10111 is H0, at least a portion of the touch element 10121 is below the surface of the wastewater. When the push rod body 10 rotates relative to the drag body 11 to form an inclination angle A and the wastewater chamber 1011 contains wastewater and the distance from the surface of the wastewater to the bottom of the airflow port 10111 is H0, the touch element 10121 is located below the surface of the wastewater, i.e., it is submerged in wastewater. In this case, the touch element 10121 can detect and judge the wastewater by contacting it, preventing the wastewater from submerging the airflow port 10111 and causing wastewater to enter the airflow port 10111.

[0090] This solution ensures that when the push rod body 10 is tilted and the airflow port 10111 is above the sewage surface, at least a portion of the tactile element 10121 is below the sewage surface. This means the airflow port 10111 is not submerged by sewage, while a portion of the tactile element 10121 is. Furthermore, when the tactile element 10121 detects the sewage surface, the airflow port 10111 is above the sewage surface, preventing sewage from submerging the airflow port 10111. This allows for stable airflow through the airflow port 10111 and prevents sewage from entering and damaging the cleaning machine 1. The bottom of the tactile element 10121 is located below the sewage surface to detect the sewage level, preventing sewage from submerging the airflow port 10111. This effectively improves the cleaning machine 1's stability in cleaning the ground when the push rod body 10 is tilted, while also ensuring user safety when operating the cleaning machine 1.

[0091] In this design, the length of the sewage chamber 1011 formed by the sewage tank 101 along the length of the push rod body 10 is H, which is the distance from the top to the bottom of the sewage chamber 1011. The design is set to 0 < H and 0 ≤ H / 2 so that the airflow port 10111 is located above the sewage surface. This means that when the airflow port 10111 is above the sewage surface and the push rod body 10 rotates relative to the main body 11 to form an angle A, a part of the tactile element 10121 can contact the sewage surface. This means that a portion of the bottom of the tactile element 10121 is submerged in sewage while the airflow port 10111 is not submerged, preventing sewage from entering the airflow port 10111 and damaging the cleaning machine 1.

[0092] And / or, wherein, when the angle A is set to be greater than 90 degrees and less than 180 degrees, that is, when the tow bar body relative to the ground drag body 11 forms an angle within this range, a structure in which a part of the tactile element 10121 contacts the liquid surface of the sewage can be realized, and a structure in which the airflow port 10111 is not submerged by the sewage can be realized, thereby effectively preventing the sewage from being submerged or entering the airflow port 10111; preferably, when the angle A is set to be greater than or equal to 150 degrees and less than or equal to 170 degrees, that is, when the tow bar body relative to the ground drag body 11 forms an angle within this range, a structure in which a part of the tactile element 10121 contacts the liquid surface of the sewage can be realized, and a structure in which the airflow port 10111 is not submerged by the sewage can be realized. At this time, the tilt angle of the push bar body 10 relative to the ground drag body 11 is large and the sewage is easy to shake and surge. By using the touch element 101181 to detect the liquid surface of the sewage, the sewage can be effectively prevented from being submerged or entering the airflow port 10111 within this angle range, ensuring that the sewage will not enter the airflow port 10111 and cause damage.

[0093] The structural positional limitation between the airflow port 10111 and the touch sensor 10121 and the sewage surface in this solution enables the touch sensor 10121 to detect and judge the sewage surface in the sewage chamber 1011 in a timely manner, preventing sewage from entering the airflow port 10111 and causing damage to the cleaning machine 1, thereby improving the safety and reliability of the cleaning machine 1.

[0094] Regarding the structural components of the airflow port 10111 and the tactile element 10121, the airflow port 10111 in this design is configured to be able to communicate with the sewage chamber 1011 by facing towards it, so that airflow can pass through and sewage can be drawn into the sewage tank 101 for collection. Simultaneously, the tactile element 10121 is positioned behind the airflow port 10111, or the distance H1 from the rear of the tactile element 10121 to the rear of the sewage chamber 1011 is less than or equal to the distance H2 from the rear of the airflow port 10111 to the rear of the sewage chamber 1011. The positional distribution of the tactile sensor 10121 and the airflow port 10111 is configured such that when the towing body is tilted relative to the towing body 11, the tactile sensor 10121 can detect and judge the liquid level of the sewage in the vertical direction in advance. The airflow port 10111 is located on the front side, which can effectively reduce the risk of sewage flooding the airflow port 10111 when the sewage tank 101 is tilted. At the same time, the tactile sensor 10121 is located on the rear side, which can improve the effect of the tactile sensor 10121 in pre-detecting the liquid level of the sewage, effectively preventing sewage from flooding the airflow port 10111 and preventing sewage from entering the airflow port 10111 and causing damage to the airflow device 13.

[0095] In this design, the tactile element 10121 and the airflow port 10111 are arranged in a parallel and spaced configuration. This ensures that when the push rod body 10 rotates relative to the main body 11 to form an inclination angle A, the sewage surface in the sewage chamber 1011 at least submerges a portion of the tactile element 10121, while the sewage surface in the sewage chamber 1011 does not submerge the airflow port 10111. The tactile element 10121 and the airflow port 10111 are arranged in a parallel and spaced configuration, primarily in the front direction, thereby enhancing the position of the tactile element 10121. The rear position of the airflow port 10111 is used to pre-detect and judge the sewage surface. When the push rod body 10 is tilted, the distance from the bottom position of the touch element 10121 to the sewage surface is less than the distance from the bottom position of the airflow port 10111 to the sewage surface. The sewage surface will first submerge the touch element 10121 to trigger the signal. At this time, the airflow device 13 can be controlled to stop working to prevent sewage from entering the airflow port 10111, thereby improving the safety of the cleaning machine 1 and better adapting to the user's needs.

[0096] In this design, regarding the positions of the airflow inlet 10111 and the tactile sensor 10121, the airflow inlet 10111 is positioned between the front of the wastewater tank 101 and the central axis W1 along the length of the push rod body 10 of the wastewater tank 101. The tactile sensor 10121 is positioned between the central axis W1 along the length of the push rod body 10 of the wastewater tank 101 and the rear of the wastewater tank 101. This division along the central axis W1 along the length of the wastewater tank 101 forms the front and rear regions of the wastewater tank 101. The front region is the front side of the wastewater tank 101. The area between the location and the central axis W1, specifically the rear area between the rear side of the sewage tank 101 and the central axis W1, is used to configure the airflow port 10111 in the front area and the touch sensor 10121 in the rear area. This ensures that the airflow port 10111 is located in front of the touch sensor 10121, allowing the touch sensor 10121 to detect and judge the sewage level in the vertical direction beforehand. The front location of the airflow port 10111 effectively reduces the risk of sewage submerging the airflow port 10111 when the sewage tank 101 is shaken or tilted, effectively ensuring that the airflow port 10111 is above the sewage level.

[0097] In this scheme, the sewage level in the sewage chamber 1011 is the sewage level in the sewage chamber 1011, which is the highest level of sewage in the sewage chamber 1011.

[0098] Regarding the positional structure of the tactile sensor 10121 within the sewage chamber 1011, in this design, the distance from the tactile sensor 10121 to the rear side of the sewage chamber 1011 is less than or equal to the distance from the tactile sensor 10121 to the central axis W1 along the length of the push rod body 10 on the sewage tank 101. This is to enable the tactile sensor 10121 to be relatively close to the rear side of the sewage chamber 1011 to pre-detect and judge the sewage surface, thereby improving the effectiveness of the tactile sensor 10121 in pre-detecting the sewage surface.

[0099] Alternatively, regarding the positional structure of the tactile sensor 10121 within the sewage chamber 1011, in this solution, a mounting portion 1013 is provided on the rear side of the sewage chamber 1011, and the tactile sensor 10121 is mounted on the mounting portion 1013. By mounting the tactile sensor 10121 on the rear side of the sewage chamber 1011, the tactile sensor 10121 can effectively detect the sewage level in advance. When the push rod body 10 tilts, the sewage gradually submerges the rear side of the sewage chamber 1011, allowing the tactile sensor 10121 to be submerged in time as the liquid level rises, thus triggering the submersion of the tactile sensor 10121 and improving the effectiveness of the tactile sensor 10121 in detecting the sewage level in advance.

[0100] The mounting part 1013 can be a cylindrical sleeve structure to install the tactile element 10121 inside. The tactile element 10121 is provided with a corresponding cylindrical structure or a sheet structure to achieve sleeve or plug-in installation.

[0101] Alternatively, regarding the positional structure of the tactile sensor 10121 within the sewage chamber 1011, in this solution, a mounting portion 1013 is provided at the top of the sewage chamber 1011 near the rear side, and the tactile sensor 10121 is mounted on the mounting portion 1013. In this case, the position of the tactile sensor 10121 can be relatively close to the rear side of the sewage chamber 1011. By mounting the tactile sensor 10121 at the top of the sewage chamber 1011, a structure is formed in which the tactile sensor 10121 extends downward to pre-detect the sewage, thereby improving the effectiveness of the tactile sensor 10121 in pre-detecting the sewage level.

[0102] Alternatively, regarding the positional structure of the tactile element 10121 within the sewage chamber 1011, in this design, a protrusion 10113 extending downwards is provided at the top of the sewage chamber 1011, and a mounting portion 1013 is provided on the protrusion 10113 near the rear side of the sewage chamber 1011. The tactile element 10121 is mounted on the mounting portion 1013. The protrusion 10113 is provided within the sewage chamber 1011, and the mounting portion 10121 is correspondingly provided on the protrusion 10113. 3. Mounting the tactile element 10121 on the protrusion 10113 helps to create a certain flow guiding effect. When sewage comes into contact with the protrusion 10113, the sewage can be guided downward in time to fall back down. At the same time, the tactile element 10121 can also form a structure for pre-detecting the sewage level. The structure of the air outlet 10111 and the tactile element 10121 can effectively enable the tactile element 10121 to pre-detect the sewage level and effectively prevent the air outlet 10111 from being submerged by sewage.

[0103] Regarding the structure of the airflow port 10111, in this solution, the distance from the center of the airflow port 10111 to the front side of the sewage chamber 1011 is less than or equal to the distance from the airflow port 10111 to the central axis W1 along the length of the push rod body 10 on the sewage tank 101. This allows the airflow port 10111 to be positioned relatively close to the front side of the sewage chamber 1011, thus keeping the airflow port 10111 away from the touch sensor 10121 and effectively preventing sewage from entering the airflow port 10111.

[0104] Alternatively, regarding the structure of the airflow port 10111, in this solution, the airflow port 10111 is positioned at the top of the sewage chamber 1011, near the front side of the sewage chamber 1011. Positioning the airflow port 10111 at the top of the sewage chamber 1011 provides a better barrier to sewage, preventing sewage from shaking or tilting and contacting the airflow port 10111. This arrangement, with the airflow port 10111 positioned relatively close to the front side of the sewage chamber 1011, keeps the airflow port 10111 away from the touch sensor 10121, effectively preventing sewage from entering the airflow port 10111.

[0105] Alternatively, regarding the structural portion of the airflow port 10111, in this solution, a protrusion 10113 extending downwards is provided at the top of the sewage chamber 1011, and the airflow port 10111 is positioned in a region near the front side of the sewage chamber 1011 at the location of the protrusion 10113. The protrusion 10113 is provided within the sewage chamber 1011, and the airflow port 10111 is positioned on the protrusion 10113, so that the airflow port 10111 is formed in a downward and / or sideward direction. The structure is connected to the sewage chamber 1011, which can better guide the airflow from the sewage chamber 1011 into the airflow port 10111. At the same time, the airflow port 10111 is positioned relatively close to the front side of the sewage chamber 1011 to prevent sewage from shaking or tilting and contacting the airflow port 10111. The airflow port 10111 is positioned relatively close to the front side of the sewage chamber 1011 to keep the airflow port 10111 away from the touch sensor 10121, so as to effectively prevent sewage from entering the airflow port 10111.

[0106] Optionally, the number of airflow ports 10111 in this scheme can be set to multiple, and the multiple airflow ports 10111 can form a concentrated airflow to draw sewage into the sewage chamber 1011 for collection. The multiple airflow ports 10111 can be arranged in an intermittent distribution structure.

[0107] In this design, to improve the ease of operation for the user when using the push rod body 10, the central axis W1 along the length of the push rod body 10 on the sewage tank 101 is positioned in front of the central axis W2 along the length of the push rod body 10. This effectively reduces the strain on the user when holding the push rod body 10 and improves ease of operation. Regarding the position of the tactile component 10121, this design positions the tactile component 10121 in the area between the rear of the sewage chamber 1011 and the central axis W2, or the distance from the tactile component 10121 to the rear of the sewage chamber 1011 is less than or equal to the distance from the tactile component 10121 to the central axis W2. In other words, the tactile component 10121 is positioned in the area between the rear of the sewage tank 101 and the central axis W2. Under the premise of the central axis W1, the position of the tactile element 10121 is further defined as being located in the area between the rear part of the sewage tank 101 and the central axis W2. This allows the tactile element 10121 to be relatively close to the rear part of the sewage tank 101 or relatively far away from the air outlet 10111. Alternatively, the distance from the tactile element 10121 to the rear part of the sewage tank 1011 can be set to be less than or equal to the distance from the tactile element 10121 to the central axis W2, thereby setting the tactile element 10121 to be relatively close to the rear part of the sewage tank 101. Both methods can enable the tactile element 10121 to effectively detect sewage in advance, prevent sewage from contacting or entering the air outlet 10111, and effectively improve the reliability of the tactile element 10121 in detecting sewage.

[0108] In this solution, regarding the positional structure of the airflow port 10111 and the tactile element 10121, when the push rod body 10 is tilted relative to the ground drag body 11 and the sewage chamber 1011 contains sewage, the height H3 from the bottom position of the airflow port 10111 to the sewage surface and / or the height H4 from the intersection of the tactile element 10121 and the surface of the sewage chamber 1011 to the sewage surface are set to be greater than the height H5 from the intersection of the top and the rear side of the sewage chamber 1011 to the sewage surface. By setting these positions, the bottom position of the airflow port 10111 and the intersection of the tactile element 10121 and the surface of the sewage chamber 1011 are both located above the intersection of the top and the rear side of the sewage chamber 1011. This allows the tactile element 10121 to detect the sewage surface in advance, preventing sewage from flooding the airflow port 10111.

[0109] Optionally, when the push rod body 10 is tilted relative to the ground drag body 11 and the sewage chamber 1011 is filled with sewage, if the sewage level submerges the position where the top of the sewage chamber 1011 intersects with the rear side of the sewage chamber 1011, then at least a portion of the bottom of the touch element 10121 will be submerged below the sewage level. This effectively allows the touch element 10121 to detect the sewage level in advance, preventing sewage from submerging the airflow port 10111. It also effectively prevents the sewage level from submerging above the position where the top of the sewage chamber 1011 intersects with the rear side of the sewage chamber 1011, thus preventing sewage from accumulating and surging and easily entering the airflow port 10111, ensuring that the airflow port 10111 is not submerged by sewage.

[0110] The structural part of the tactile module 1012 in this solution mainly consists of two tactile elements 10121 that extend towards the sewage chamber 1011. When both tactile elements 10121 come into contact with sewage, the tactile module 1012 is triggered to generate a signal indicating that sewage has been detected. The two tactile elements 10121 can be arranged in a spaced-apart configuration along the front-back direction of the sewage chamber 1011, and when the sewage chamber 1011 contains sewage, the height from the bottom of the front tactile element 10121 to the sewage surface is greater than or equal to... The bottom of the rear-mounted tactile element 10121 is positioned at the height of the sewage surface. At this height, the two tactile elements 10121 distributed in the front and rear structures can more accurately detect the sewage surface. When the sewage is shaken or tilted, it is easy for the sewage to surge and intermittently contact the rear-mounted tactile element 10121. Therefore, a single tactile element 10121 cannot accurately detect the sewage surface position. When two tactile elements 10121 are set to both contact the sewage surface, the sewage surface can be determined more accurately, improving the reliability and stability of the tactile element 10121 in detecting the liquid surface.

[0111] Alternatively, the tactile module 1012 in this solution is mainly composed of two tactile elements 10121 that extend towards the sewage chamber 1011. When both tactile elements 10121 come into contact with sewage, the tactile module 1012 is triggered to generate a signal indicating that sewage has been detected. The two tactile elements 10121 are spaced apart along the left-right direction of the sewage chamber 1011, and when the sewage chamber 1011 contains sewage, the bottom positions of the two tactile elements 10121 are... With the sewage level equal to the water level, the two tactile sensors 10121 distributed on the left and right can more accurately detect the sewage level. Because the sewage in the sewage chamber 1011 is prone to shaking or tilting, the sewage is prone to surging and intermittently contacting the tactile sensors 10121. Therefore, a single tactile sensor 10121 cannot accurately detect the sewage level. When two tactile sensors 10121 are set to contact the sewage level, the sewage level can be determined more accurately, improving the reliability and stability of the tactile sensor 10121 in detecting the liquid level.

[0112] Regarding the structure of the sewage tank 101 for collecting sewage, this design includes an inlet 10114 at the upper part of the sewage chamber 1011, or a protrusion 10113 extending downwards from the top of the sewage chamber 1011 with an inlet 10114 on the protrusion 10113. The inlet 10114 is designed to face the sewage chamber 1011 and communicate with it. The inlet 10114 allows sewage to enter and be collected within the sewage chamber 1011. This is primarily for use when the sewage tank 101 is installed, allowing it to connect with the push rod body 10 to collect sewage into the sewage chamber 1011, preventing secondary pollution of the ground. To further prevent sewage from being drawn into the airflow inlet 10111 during its entry into the sewage chamber 1011, this design positions the inlet 10114 behind the airflow inlet 10111 or within the sewage tank 1011. Within the area between the central axis W1 along the length of the push rod body 10 and the rear side of the sewage tank 101, the sewage inlet 10114 is positioned behind the airflow inlet 10111 to allow sewage to enter. The sewage inlet 10114 and the airflow inlet 10111 are spaced apart to prevent sewage from being sucked into the airflow inlet 10111 when it enters the sewage chamber 1011. This facilitates the concentration of sewage into the sewage chamber 1011. Alternatively, the sewage inlet 10114 can be positioned within the area between the central axis W1 along the length of the push rod body 10 and the rear side of the sewage tank 101 so that the sewage tank 101 is positioned behind the central axis W1 for sewage entry. This achieves a large front-to-back distance between the airflow inlet 10111 and the sewage inlet 10114, effectively preventing sewage from entering the airflow inlet 10111 and causing damage to the airflow device 13.

[0113] In this solution, regarding the structural components of the cleaning machine 1 for cleaning the ground and the wastewater portion, a roller 111 for contacting the ground and cleaning is provided on the mop body 11. A clean water supply structure is also provided on the mop body 11 to supply clean water to the roller 111. The clean water supply structure includes a water supply mechanism, which can be a water pump, electromagnetic pump, or electromagnetic valve to achieve the effect of supplying clean water to the roller 111. After contacting the clean water, the roller 111 forms a wet structure to clean the ground. Simultaneously, a considerable amount of wastewater is generated during the cleaning process of the roller 111. This wastewater can be collected into the wastewater chamber 1011, mainly by the suction force of the airflow generated by the airflow device 13. Wastewater is collected within chamber 1011. The drum 111 is configured to communicate with the inlet 10114 via a wastewater inlet channel. A filter device is installed between the drum 111 and the wastewater inlet channel, ensuring that wastewater on the drum 111 is filtered before entering the wastewater inlet channel. Wastewater on the drum 111 enters the wastewater inlet channel under the suction of airflow and is filtered by the filter device before entering the wastewater chamber 1011. This prevents blockages during collection, effectively filtering the wastewater before it enters the wastewater inlet channel and then the wastewater chamber 1011, improving the reliability of wastewater collection and reducing the likelihood of blockages.

[0114] Alternatively, for the sewage collection structure, a sewage zone is set on one side of the drum 111 to collect sewage from the drum 111. The drum 111 can be connected to the sewage inlet 10114 through the sewage zone. The sewage zone is located on one side of the drum 111 to pre-collect sewage from the drum 111. A pressing device can be set to squeeze the sewage out of the drum 111. The squeezed sewage flows into the sewage zone under gravity. At this time, the sewage will form a certain accumulation effect in the sewage zone. In order to prevent the sewage from clogging during the collection process, this solution is equipped with a filtration device in the sewage zone to form a structure in which the sewage from the drum 111 is filtered before entering the sewage inlet 10114. This realizes that the sewage is filtered in the sewage zone first, and the filtered sewage then enters the sewage inlet 10114 and then enters the sewage chamber 1011 to collect the sewage. This can improve the reliability of sewage collection and reduce the likelihood of clogging.

[0115] Optionally, in the above scheme, the filtration device may include a filter element with multiple filter holes to achieve the filtration effect on wastewater.

[0116] Optionally, the roller 111 is configured as a cylindrical structure, and the number of rollers 111 can be set as needed. The outer layer of the roller 111 is made of soft cloth or sponge material to achieve the effect of cleaning by contacting the ground.

[0117] The mop body 11 is equipped with a drive mechanism and a motor. The motor drives the roller 111 to rotate and roll, so that the roller 111 can contact the ground for cleaning. The drive mechanism can be a belt pulley transmission structure or a structure with multiple gears or planetary gears to appropriately reduce the rotation speed of the motor, thereby driving the roller 111 to rotate and roll.

[0118] Regarding the structural design of the airflow channel and sewage inlet channel on the sewage tank 101, this solution provides a partition component 10115 at the upper part of the sewage chamber 1011. A ring-shaped sealing component 10116 is provided at the upper part of the partition component 10115. When the sewage tank 101 is installed in place, the sealing component 10116 achieves a sealing effect between the sewage tank 101 and the push rod body 10. The partition component 10115 is provided with an airflow chamber 101151 and a sewage inlet chamber 101152, which are designed as independent cavity structures. This allows airflow and sewage to communicate independently with the sewage chamber 1011 within their respective cavities. Furthermore, the airflow chamber 101151 is connected to the airflow outlet 10111, allowing airflow to enter from the airflow outlet 10111. The wastewater enters the airflow chamber 101151 independently and then enters the airflow device 13. The structure of the wastewater inlet chamber 101152 and the wastewater inlet 10114 being connected allows wastewater to enter the wastewater chamber 1011 independently, and then enter the wastewater chamber 1011 through the wastewater inlet 10114. This ensures that wastewater and airflow have independent chambers connected to the wastewater chamber 1011, effectively preventing wastewater from being sucked into the airflow inlet 10111 when entering the wastewater chamber 1011. Simultaneously, the airflow chamber 101151 can concentrate the airflow, preventing its diffusion and ensuring a stable airflow for wastewater absorption. This effectively prevents wastewater from being sucked into the airflow inlet 10111 during its entry into the wastewater chamber 1011.

[0119] Regarding the structural part of the airflow channel, the push rod body 10 is provided with an airflow interface 102. The airflow interface 102 is configured to be open towards the side or top of the push rod body 10. The structure of the airflow port 10111 helps to prevent sewage from flowing back into the airflow interface 102. Even if sewage accidentally enters the airflow port 10111, it can be effectively prevented from entering the airflow interface 102. The airflow interface 102 is configured to be through-type towards the side or top of the push rod body 10, forming a structure that communicates with the airflow cavity 101151. The airflow structure forms during the through-type process. The airflow channel structure effectively prevents sewage from entering and improves the stability of airflow supply. The airflow interface 102 is mainly connected to the airflow device 13 for airflow passage. When the airflow device 13 is working, the airflow in the sewage chamber 1011 enters the airflow interface 102 through the airflow port 10111 and returns to the airflow device 13 before being discharged. This creates a negative pressure suction force in the sewage chamber 1011 to suck up the sewage on the roller 111, thus collecting the sewage into the sewage chamber 1011. Furthermore, the structure of the airflow channel and the airflow interface 102 are not prone to sewage backflow.

[0120] Regarding the wastewater structure, the push rod body 10 is equipped with a wastewater inlet 103. The wastewater inlet 103 is mainly used for wastewater to enter and be collected in the wastewater chamber 1011. The wastewater inlet 103 is designed to be open towards the side or top of the push rod body 10, and correspondingly, it is designed to be through-type towards the side or top of the push rod body 10, forming a structure that communicates with the sewage inlet chamber 101152. At the same time, the wastewater inlet 103 is also connected to the roller 111, and can be connected to the sewage inlet channel or sewage area to allow the wastewater formed on the roller 111 to enter the wastewater chamber 1011. The structure of the wastewater inlet 103 facilitates the entry of wastewater into the wastewater chamber 1011 under the action of gravity after passing through the wastewater inlet 103, achieving effective collection of wastewater. At the same time, it can also effectively prevent the problem of wastewater backflow when the push rod body 10 is tilted, preventing wastewater from flowing back in.

[0121] Specifically, the sewage inlet 103 is also configured to be connected to the roller 111 on the mop body 11, and can be connected to the sewage inlet channel or the sewage area. It can be connected to the roller 111 through the sewage inlet channel or the sewage area to realize the sewage on the roller 111 being sucked into the sewage chamber 1011. The sewage suction and collection can effectively prevent secondary pollution of the ground by sewage and improve the cleaning effect of the roller 111 on the ground.

[0122] In this scheme, an airflow device 13 is mainly set on the push rod body 10 to generate airflow. The airflow device 13 mainly realizes the suction force of the airflow, which is mainly used to generate suction force on the sewage tank 101, so that the sewage on the roller 111 can be sucked in and collected into the sewage tank 101, thereby realizing the centralized collection of sewage into the sewage chamber 1011.

[0123] Alternatively, the airflow device 13 can be configured as a fan structure with high suction power, or as a vacuum pump structure.

[0124] The cleaning machine 1 in this solution can discharge sewage from the sewage tank 101 to facilitate the connection and maintenance of the cleaning machine 1 for sewage treatment. Specifically, a sewage discharge channel 10117 is provided in the sewage chamber 1011. The sewage discharge channel 10117 is mainly used for the passage of sewage in the sewage chamber 1011. The end of the sewage discharge channel 10117 is set near the bottom of the sewage chamber 1011 so that the sewage in the sewage chamber 1011 can effectively enter the sewage discharge channel 10117. The sewage discharge channel 10117 is set to extend upward toward the sewage chamber 1011 and pass through the top surface of the sewage tank 101. A drain outlet 101171 is formed on the side surface, allowing sewage in the sewage chamber 1011 to enter the drain channel 10117 under the action of power. The sewage then flows through the drain channel 10117 and is discharged through the drain outlet 101171 to the outside of the sewage tank 101. The drain outlet 101171 is positioned on the top or side surface of the sewage tank 101 to facilitate the installation and connection of the sewage tank 101, forming a sewage flow channel. This allows for better connection and transfer of sewage from the sewage chamber 1011 to the outside of the sewage tank 101. The push rod body 10 is also equipped with a drain outlet. The outlet 105 is open towards the side or bottom of the push rod body 10, forming a structure that communicates with the outside of the push rod body 10. The outlet 105 is used to connect with the outside of the cleaning machine 1 to discharge sewage from the sewage chamber 1011. For example, if a base station is set up to maintain the cleaning machine 1, the cleaning machine 1 can connect with the base station through the outlet 105 so that the sewage in the sewage chamber 1011 can enter the base station for collection, achieving the effect of sewage collection. A sewage channel is provided between the outlet 105 and the discharge port 101171. The sewage channel connects the outlet 105, the discharge port 101171, and the sewage chamber 1011, forming a passageway through which sewage can pass. The sewage in the sewage chamber 1011 can flow under the action of power and finally be discharged outward through the outlet 105. At the same time, this solution is equipped with a sewage discharge module 10118 on the sewage channel. By setting the sewage discharge module 10118, the sewage can be discharged stably and effectively. During the sewage discharge process, it is not easy to cause blockage problems. At the same time, when the sewage is closed and no sewage is discharged, it is not easy to cause air leakage problems, which makes the cleaning machine 1 more stable and reliable in operation.

[0125] In this design, a sewage discharge module 10118 is mainly used to discharge sewage from the sewage tank 101. The sewage discharge module 10118 includes an actuating element 101181 and a sewage discharge component 101182. The actuating element 101181 is located outside the sewage discharge component 101182 and is movable. A sewage discharge channel 1011821 is provided inside the sewage discharge component 101182. When the actuating element 101181 moves to press against the sewage discharge component 101182, the actuating element 101181 does not contact the sewage discharge channel 1011821 or the sewage within it, thus sealing the sewage discharge channel 1011821. The pressing against the sewage discharge component 101182 is mainly achieved through the movement of the actuating element 101181. When the actuator 101181 moves to press against the drain component 101182, the drain channel 1011821 inside the drain component 101182 is sealed and closed. During the pressing process, the actuator 101181 does not contact the drain channel 1011821 or the sewage, effectively preventing sewage from contaminating the actuator 101181 and preventing blockages caused by garbage accumulation due to contamination. When the actuator 101181 does not press against the drain component 101182, the drain component 101182 is in a normal state, and the drain channel 1011821 is open, allowing sewage to pass through and be discharged.

[0126] The actuator 101181 is configured to move relative to the drain component 101182 between a first position and a second position. The actuator 101181 primarily moves to the outer side of the drain component 101182. When the actuator 101181 is in the first position, the drain channel 1011821 is open, and the actuator 101181 does not press against the drain component 101182, allowing normal passage of sewage. When the actuator 101181 is in the second position, it presses against the drain component 101182, closing the drain channel 1011821. The movement of the actuator 101181 achieves the opening and closing effect of the drain channel 1011821, thus enabling the drainage of sewage when needed. When sewage is discharged from the water tank 101, the sewage discharge channel 1011821 is opened to discharge sewage. When sewage needs to be collected into the sewage tank 101, the sewage discharge channel 1011821 can be closed to form a sealed and leak-proof structure. The sewage discharge module 10118 of this solution has a simple structure. The opening and closing effect of the sewage discharge channel 1011821 in the sewage discharge component 101182 is achieved by setting the sewage discharge component 101182 and the trigger component 101181. At the same time, the trigger component 101181 will not come into contact with sewage, so that the sewage discharge component 101182 can be used independently for the passage of sewage. Since the trigger component 101181 does not come into contact with sewage, it is not easy for sewage or garbage to get stuck in it, and it is not easy for the sewage to cause blockage and reduced reliability due to the squeezing of garbage.

[0127] Optionally, the actuator 101181 can be configured as a translational motion structure, or a rotational swing motion structure, or a telescopic and deformable motion structure. The motion of the actuator 101181 can be configured as needed, as long as it can form a pressing structure on the sewage discharge component 101182.

[0128] Optionally, the drain component 101182 can be configured as a soft and deformable structure, so that when the actuating component 101181 presses the drain component 101182, the drain component 101182 can deform to seal and close the drain channel 1011821. At the same time, when the actuating component 101181 does not press the drain component 101182, the drain component 101182 can recover under its own elastic force, so that the drain channel 1011821 is in an open structure. Thus, the actuating component 101181 can achieve the opening and closing effect of the drain channel 1011821 by moving the drain component 101182.

[0129] For the motion structure of the actuator 101181, a motor can be installed. The motor can be mounted on a motor bracket, which is mounted on the housing of the sewage module 10118. A transmission component is connected to the motor shaft. The transmission component can drive the actuator 101181 to move or rotate. For example, the motor can drive the actuator 101181 to move back and forth by rotating in both directions. Or, the motor can drive the actuator 101181 to rotate and swing within a certain angle range. The movement or swing of the actuator 101181 can achieve the pressing effect on the sewage discharge component 101182, thereby achieving the opening and closing effect of the sewage discharge channel 1011821.

[0130] Alternatively, the actuator 101181 can be configured as a telescopic and deformable motion structure. A cylinder can be used to drive the actuator 101181 to achieve the telescopic deformation effect. The telescopic deformation of the actuator 101181 achieves a pressing effect on the drain component 101182. For example, when the actuator 101181 extends, it can press the drain component 101182; when the actuator 101181 retracts, it forms a structure that does not press the drain component 101182. Alternatively, the actuator 101181 can be configured to allow air to be pumped in. The structure allows the contact element 101181 to extend and deform when the air pump injects air into it, so that the contact element 101181 can press against the sewage discharge element 101182. When other parts of the contact element 101181 are extracted, the contact element 101181 shrinks and deforms, so that the contact element 101181 can no longer press against the sewage discharge element 101182. It can also achieve the effect of pressing against the sewage discharge element 101182 and not pressing against it, thereby realizing the opening and closing effect of the sewage discharge channel 1011821.

[0131] To further improve the sewage discharge module 10118's sewage discharge efficiency and sealing effect when not discharging sewage, this solution can also provide a pressing part on the actuator 101181 to press the sewage discharge component 101182. The pressing part has at least one depressurization part, which is configured to form a recessed structure with its outer end face facing away from the sewage discharge component 101182 relative to the pressing part. When the actuator 101181 is in the second position, the depressurization part forms a dirt-receiving part at the corresponding position on the sewage discharge component 101182, and the portion of the pressing part other than the depressurization part forms a flow-blocking part at the corresponding position on the sewage discharge component 101182. The part achieves a sealing and closing effect on the sewage discharge channel 1011821. The structure of the depressurization part allows for a relatively short stroke when pressing on the sewage discharge part 101182. At this time, the position of the depressurization part cannot form a intercepting part on the sewage discharge part 101182. Instead, the depressurization part forms a dirt-containing part on the sewage discharge part 101182. When there is garbage in the sewage discharge channel 1011821, the garbage is squeezed under the pressing of the pressing part to move the garbage to the dirt-containing part. This prevents the pressing part from squeezing the garbage, which would cause the intercepting part to have a poor sealing effect on the sewage discharge channel 1011821. The intercepting part stably seals the sewage discharge channel 1011821 to achieve a closing effect.

[0132] To further improve the sewage discharge module 10118's effectiveness in discharging sewage and its sealing performance when not discharging sewage, this solution can also set the Young's modulus of the sewage discharge component 101182 to be less than 10 GPa. The sewage discharge component 101182 can be made of soft silicone material, but its Young's modulus must be less than 10 GPa to ensure that it can maintain normal rebound over a long period, allowing the trigger component 101181 to perform multiple actions on the sewage discharge component 101182. The pressing action achieves the opening and closing effect of the sewage channel 1011821; or a spring layer or elastic element is provided on the outside of the sewage component 101182. The spring layer or elastic element can better drive the sewage component 101182 to recover and rebound so that when the trigger 101181 does not press the sewage component 101182, the sewage component 101182 can effectively rebound and recover so that the sewage channel 1011821 is in an open structure, thus improving the stable opening structure of the sewage channel 1011821.

[0133] To prevent sewage from flowing into the sewage tank 101 and causing damage to the blower when the push rod body 10 is tilted, a flow-blocking component 10112 is installed inside the sewage chamber 1011. The flow-blocking component 10112 primarily obstructs sewage flow, especially when the user rotates the push rod body 10 back and forth, causing it to sway, or when the push rod body 10 is tilted. The flow-blocking component 10112 effectively prevents sewage from accumulating and flowing into the airflow outlet 10111, or even accumulating there. Specifically, the flow-blocking component 10112 has a flow-blocking part 101121. 01121 forms a shielding structure to block sewage from at least a portion of the cross-section of the sewage chamber 1011. The flow-blocking part 101121 is located in the area above the middle of the length of the sewage chamber 1011. When the push rod body 10 shakes or tilts, the sewage in the sewage chamber 1011 will flow in the direction of shaking or tilting of the sewage tank 101. The flow-blocking part 101121 in this solution will block the flow of sewage on the cross-section of the sewage chamber 1011, preventing sewage from accumulating and entering the air outlet 10111. This can effectively prevent sewage from entering the air outlet 10111 and then entering the airflow device 13, which would cause damage to the airflow device 13, thus improving the overall reliability and safety of the cleaning machine 1.

[0134] To improve the sewage discharge channel 10117 for better sewage entry, this solution involves installing the sewage discharge channel 10117 on the anti-flow component 10112. A limiting structure can be installed on the anti-flow component 10112 to limit and fix the sewage discharge channel 10117 on it, preventing the anti-flow component 10112 from shifting. Furthermore, the anti-flow component 10112 is also equipped with a rotatable swing component 101122. At least the end of the sewage discharge channel 10117 is mounted on the swing component 101122, allowing the swing component 101122 to be driven... The end of the sewage discharge channel 10117 swings vertically up and down. The swinging component 101122 is used to stably press the end of the sewage discharge channel 10117 close to the bottom of the sewage chamber 1011. At the same time, the swinging component 101122 can also make the end of the sewage discharge channel 10117 move vertically to allow sewage to enter the sewage discharge channel 10117 better, so that the sewage in the sewage chamber 1011 can be discharged to the outside through the sewage discharge channel 10117 better.

[0135] Specifically, a rotating shaft and a rotating shaft hole are provided between the swing member 101122 and the anti-flow member 10112 to enable the swing member 101122 to be rotatably mounted on the anti-flow member 10112, thereby enabling the swing member 101122 to rotate and swing on the anti-flow member 10112 so that the end of the sewage discharge channel 10117 can better approach the bottom position of the sewage chamber 1011.

[0136] Regarding the structural components of the sewage tank 101, the push rod body 10 of this design is provided with a mounting cavity 104. The mounting cavity 104 has a recessed structure for mounting the sewage tank 101. The sewage tank 101 is detachably mounted on the mounting cavity 104, allowing it to be detachably installed within the mounting cavity 104 via a snap-fit ​​mechanism. A first energy replenishment module is provided within the mounting cavity 104, featuring two spaced electrode plates. A corresponding second energy replenishment module is provided on the sewage tank 101, also featuring two corresponding electrode plates. When the sewage tank 101 is in place, the first energy replenishment module can activate... The two electrode plates on the first power supply module and the two electrode plates on the second power supply module form a corresponding contact structure, thereby realizing the power supply effect on the sewage tank 101. The touch sensor 10121 is mainly configured to be connected to the second power supply module, so that the first power supply module and the second power supply module can supply power to the touch sensor 10121 on the touch sensor module 1012, so that the touch sensor module 1012 can sense the liquid level in the sewage chamber 1011. When the sewage tank 101 is installed in place, the first power supply module and the second power supply module are connected to form a power supply structure, thereby realizing the power supply structure for the touch sensor module 1012.

[0137] Optionally, a power supply unit is provided on the push rod body 10. The power supply unit is connected to the first energy replenishment module to realize the structure that the power supply unit can supply power to the first energy replenishment module. When the sewage tank 101 is installed in place, the power supply unit supplies power to the touch module 1012 through the first energy replenishment module and the second energy replenishment module.

[0138] The control method of the cleaning machine 1 in this solution mainly uses the touch module 1012 to detect and judge the sewage level in the sewage chamber 1011, and controls the working state of the airflow device 13 in a timely manner to prevent sewage from being sucked into the airflow device 13 and causing damage to the airflow device 13.

[0139] The control method of the cleaning machine 1 includes the cleaning machine 1 as described above. The cleaning machine 1 also includes a control unit 12 and an airflow device 13. The airflow device 13 is directly or indirectly connected to the airflow port 10111. The control unit 12 controls the start and stop of the airflow device 13. When the control unit 12 controls the airflow device 13 to start working, the sewage is sucked into the sewage tank 101 for collection. When the control unit 12 controls the airflow device 13 to stop working, the collection of sewage is stopped.

[0140] The control unit 12 is electrically connected to the tactile module 1012 and the airflow device 13, respectively;

[0141] It also includes the following control methods:

[0142] Step S1: The control unit 12 detects the time value T of continuous contact between the touch sensor 10121 and the sewage in the sewage chamber 1011, where T is a non-empty value, and compares the time value T with the preset time threshold T0 in the control unit 12.

[0143] Step S2: If the detected time value T is less than the time threshold T0, control the airflow device 13 to stop working and the stop time is T1, where T1 is less than or equal to 30 or 60 seconds. Then control the airflow device 13 to restart working and proceed to step S1.

[0144] Step S2': If the detected time value T is greater than or equal to the time threshold T0, control the airflow device 13 to stop working and indicate that the sewage is full.

[0145] In step S1, T is a non-empty value, meaning T is not equal to 0. The main detection is the time value formed by the continuous contact between the tactile sensor 10121 and the sewage. This can be understood as the continuous and uninterrupted contact between the tactile sensor 10121 and the sewage in the sewage chamber 1011 within the time value T. This allows for further comparison of the time value T with the time threshold T0, thereby determining the true state of the sewage level in the sewage chamber 1011.

[0146] In this scheme, T0 is set to be greater than or equal to 10 seconds, or T1 is set to be greater than or equal to 5 seconds, or T1 is set to be greater than or equal to 5 seconds and less than T0. Specifically, T1 can be set to be greater than or equal to 5 seconds, or T1 can be set to be greater than or equal to 5 seconds and less than T0 or less than 10 seconds. If the time T1 is larger, the user will have to wait for a relatively long time. If the time T1 is smaller, the current detection state will not change. Therefore, the value of T1 in this scheme can enable the user to reduce the tilt angle of the push rod body 10 or stop shaking the push rod body 10 within this time period so that the sewage in the sewage tank 101 is in a normal state. The actual sewage level in the sewage tank 101 can be reflected by the touch sensor 10121.

[0147] As can be seen, in the control method of this scheme, the working state of the airflow device 13 can be further controlled by comparing the continuous contact time T between the detection touch element 10121 and the sewage in the sewage chamber 1011 with the preset time threshold T0 in the control unit 12. This allows the control unit 12 to determine whether the airflow device 13 continuously stops working to prompt the user to maintain and empty the sewage tank 101, or to temporarily stop working so that the touch element 10121 can further accurately detect and judge the sewage in the sewage chamber 1011. When the user operates the push rod body 10 and it is shaking or tilted, the touch element 10121 does not necessarily determine that the sewage tank 101 is full when it detects the sewage level in the sewage chamber 1011. It can more accurately judge the sewage level in the sewage tank 101 so that the user can operate the cleaning machine 1 to clean the ground. This can effectively prevent the problem of the airflow device 13 continuously stopping working when the sewage tank 101 is not full, which would cause the user to frequently maintain the sewage tank 101.

[0148] Optionally, the control unit 12 has a preset time threshold T0, where T0 is greater than or equal to 10 seconds. This means that if the tactile sensor 10121 is in continuous contact with the sewage during the time period T0, it indicates that the sewage level is in the true state, meaning that the sewage chamber 1011 is full. This eliminates the possibility that the tactile sensor 10121 is in contact with the sewage while the sewage is shaking or tilting. This allows the tactile sensor 10121 to be controlled to determine the true sewage level, thus improving the accuracy of the tactile sensor 10121 in detecting the sewage level.

[0149] In step S2, if the detected time value T is less than the time threshold T0, the airflow device 13 is controlled to stop working for a time of T1, where T1 is less than or equal to 30 or 60 seconds. Then, the airflow device 13 is controlled to restart and proceed to step S1. This process can be mainly determined when the user operates the push rod body 10 in a state of shaking or tilting, and the touch element 10121 is in intermittent contact with the sewage, that is, the continuous contact time value T is less than the time threshold T0. At this time, it can be understood that the sewage in the sewage chamber 1011 is not full, but only formed under the structure of sewage shaking or tilting. The intermittent contact between the touch sensor 10121 and the sewage allows the user to stop rotating, tilting, or shaking the push rod body 10 during this period by controlling the airflow device 13 to restore the sewage level in the sewage chamber 1011 to a stable or vertical position to return to normal. If the sewage is not shaken or tilted, the sewage level will drop, preventing the touch sensor 10121 from contacting the sewage. After the user waits for time T1, the airflow device 13 can be controlled to start and continue the cleaning task of the cleaning machine 1, effectively adapting to the user's needs in various scenarios.

[0150] In step S2', if the contact time T between the touch sensor 10121 and the sewage is greater than or equal to the time threshold T0, it can be understood that the duration of contact between the touch sensor 10121 and the sewage meets the threshold. It can be determined that the sewage in the sewage chamber 1011 is full. At this time, the user can be prompted that the sewage is full and the cleaning machine 1 can start the airflow device 13 to suck up the sewage after the sewage needs to be maintained.

[0151] The control method of this solution can effectively and accurately detect and determine the actual sewage level in the sewage tank 101, and can also effectively adapt to user needs and improve the user experience.

[0152] The control method of the cleaning machine 1 in this solution mainly uses the touch module 1012 to detect and judge the sewage level in the sewage chamber 1011, and controls the working status of the water supply mechanism in a timely manner to prevent the sewage from being effectively collected and to prevent the water supply mechanism from supplying clean water when the sewage chamber is full.

[0153] The control method of the cleaning machine 1 includes the cleaning machine 1 as described above. The cleaning machine 1 also includes a control unit 12, a water supply mechanism, and an airflow device 13. The airflow device 13 is directly or indirectly connected to the airflow port 10111. The control unit 12 controls the start and stop of the water supply mechanism. When the water supply mechanism is started, it can provide clean water to the ground or the roller 111. When the water supply mechanism stops working, it stops supplying water. The control unit 12 controls the start and stop of the airflow device 13. When the control unit 12 controls the airflow device 13 to start working, it realizes the suction of sewage into the sewage tank 101 for collection. When the control unit 12 controls the airflow device 13 to stop working, it realizes the stop of sewage collection.

[0154] The control unit 12 is electrically connected to the touch module 1012, the water supply mechanism, and the airflow device 13, respectively, so that the control unit 12 can control the water supply mechanism and the airflow device 13.

[0155] Control unit 12 controls airflow device 13 to start operation and enter the following control mode:

[0156] Step S01: Control the water supply mechanism to start working;

[0157] Step S02: The control unit 12 is set with a detection cycle of time value t, where time value t is greater than or equal to 2 seconds;

[0158] If the touch sensor 10121 is detected to be in contact with sewage in the sewage chamber 1011 during a single detection cycle, the water supply mechanism will be controlled to stop working during that detection cycle.

[0159] Furthermore, if the time value t1 of continuous contact between the touch sensor 10121 and the sewage in the sewage chamber 1011 is greater than or equal to the preset time threshold t0 in the control unit 12 within a single detection cycle, it indicates that the sewage chamber is full.

[0160] And if the cumulative contact time t2 between the tactile sensor 10121 and the sewage in the sewage chamber 1011 is greater than or equal to 0.5 times the time value t within a single detection cycle, it indicates that the sewage chamber is full.

[0161] In step S02, if the touch sensor 10121 comes into contact with sewage within a single detection cycle, the water supply mechanism is controlled to stop working to prevent excessive water from contacting the roller 111 and causing sewage to be unable to be effectively collected. At the same time, the continuous contact time between the touch sensor 10121 and the sewage can be detected within a single detection cycle. It can be understood that the duration of contact between the touch sensor 10121 and the sewage meets the threshold, and it can be determined that the sewage chamber 1011 is full. If the continuous contact time t1 between the touch sensor 10121 and the sewage in the sewage chamber 1011 is greater than or equal to the preset time threshold t0 in the control unit 12, the user can be prompted that the sewage is full and the sewage needs to be maintained before the cleaning machine 1 can start the airflow 13 to work and suck up the sewage. Simultaneously, the cumulative contact time t2 between the tactile sensor 10121 and the sewage in the sewage chamber 1011 can be detected within a single detection cycle. During this time, the tactile sensor 10121 can intermittently contact the sewage multiple times, such as when the sewage is shaking and intermittently contacts the tactile sensor 10121. When the cumulative contact time t2 is greater than or equal to 0.5 times the time value t, it indicates that the sewage is full. At this time, it can be determined that the sewage in the sewage chamber 1011 is in a state of being almost full or already full, which is why the cumulative contact time between the tactile sensor 10121 and the sewage is greater than or equal to 0.5 times the time value t. Therefore, it is directly determined that the sewage is full and a sewage full prompt is issued, prompting the user to maintain the sewage in the sewage tank 101 before operating the cleaning machine 1 to perform the cleaning task.

[0162] The method also includes step S03: if step S02 does not indicate that the sewage is full, then step S01 is entered, which is to control the water supply mechanism to restart to supply water to the ground or roller 111 so that the cleaning machine 1 can continuously clean the ground.

[0163] Optionally, in the above method, the control unit 12 controls the airflow device 13 to continuously absorb sewage. The airflow device 13 is only controlled to stop working when the user stops the cleaning machine 1 or when the cleaning machine 1 is automatically shut down, so that the airflow device 13 can continuously absorb and collect sewage, effectively preventing a large amount of sewage from remaining on the roller 111 and effectively preventing sewage from causing secondary pollution to the ground.

[0164] Optionally, the time period of a single detection cycle can be set to a time value t greater than or equal to 5 seconds and less than or equal to 10 seconds, so as to more stably detect and judge sewage.

[0165] The control method of this scheme can effectively control the water supply status of the water supply mechanism, preventing the problem of secondary pollution to the ground caused by the continuous water supply when the sewage tank is full and the sewage cannot be collected into the sewage tank 101. In order to effectively collect the sewage formed by the contact of the roller 111 with the clean water provided by the water supply mechanism, the sewage formed during the operation of the cleaning machine 1 is effectively collected, preventing the residual sewage on the roller 111 from causing secondary pollution to the ground, and preventing the water supply mechanism from supplying clean water when the sewage tank is full.

[0166] It is understandable that during user operation of the cleaning machine 1, the user will rotate or reciprocate the push rod body 10. This causes the wastewater tank 101 to sway or sway back and forth with the push rod body 10, resulting in the wastewater inside the wastewater tank 101 swaying within the wastewater chamber 1011. At some point, the wastewater may come into contact with the touch sensor 1012, triggering the touch sensor 10121. However, at this time, the wastewater tank 101 is not full, so the wastewater level detected by the touch sensor 10121 is inaccurate. Simultaneously, when the user operates the push rod body 10 in a certain position... When the main body 11 is tilted at a relatively large angle, the sewage in the sewage tank 101 will tilt along with the tilt of the push rod main body 10. At this time, the sewage is more likely to come into contact with the touch sensor 10121, causing the touch sensor 10121 to be triggered. The control method of this solution can effectively determine whether the liquid level in the sewage tank 101 is full and control the working state of the airflow device 13 in a timely manner. At the same time, it can effectively prevent sewage from entering the airflow port 10111 or the airflow device 13, which would damage the airflow device 13. This improves the stability of the cleaning machine 1's working process and enhances the stability of the touch sensor module 1012 in detecting the sewage liquid level.

[0167] This solution effectively addresses the issue of the user stopping the cleaning machine 1 after the touch sensor 10121 is triggered when the sewage level in the sewage tank 101 is not full or is low. It prevents the system from notifying the user that the sewage tank 101 is full or needs maintenance when the sewage level in the sewage tank 101 is not full or is low. This improves the accuracy and reliability of the sewage level detection in the sewage tank 101 and prevents the touch sensor 10121 from misjudging the sewage level, resulting in a poor user experience.

[0168] Working Principle: The cleaning machine 1 in this solution mainly achieves floor cleaning. The cleaning machine 1 is composed of a mop body 11 and a push rod body 10 to form a handheld cleaning machine structure. A wastewater tank 101 is set on the push rod body 10 to collect and hold wastewater. Specifically, a roller 111 is set. Wastewater is generated by the roller 111 during the mopping process, and then the wastewater is sucked into the wastewater tank 101 by the airflow device 13. This solution uses the structural position of the touch sensor 1012 and the airflow port 10111 to ensure that when the push rod body 10 is tilted relative to the mop body 11, the wastewater level in the wastewater chamber 1011 at least submerges a part of the touch sensor 10121, and the wastewater level in the wastewater chamber 1011 does not submerge the airflow port 10111. 111 can effectively prevent sewage from flooding the airflow port 10111 when the sewage tank 101 is tilted, or even prevent sewage from entering the airflow port 10111 and entering the airflow device 13, causing damage to the airflow device 13. The touch module 1012 detects and judges the liquid level of the sewage. Combined with the tilt angle of the push rod body 10, the positional relationship and limiting structure between the touch module 1012 and the airflow port 10111 are set to enable the touch module 1012 to reliably detect whether the liquid level of the sewage will flood the airflow port 10111. This allows for advance control of the working state of the airflow device 13, preventing sewage from flooding the airflow port 10111, improving the overall stability and safety of the cleaning machine 1, and the reliability of the sewage tank 101 in collecting sewage.

[0169] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention. In practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention, and all such changes are within the protection scope of the present invention.
