Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a sewage tank, a cleaning equipment and a cleaning system. BACKGROUND

[0002] The cleaning equipment has the advantages of environmental protection, energy saving, high efficiency and the like. With the increasing awareness of household cleaning efficiency, the cleaning equipment has been gradually widely used in daily production and life.

[0003] At present, after the cleaning equipment completes the work, the user usually cleans the sewage tank in time to discharge the sewage and garbage in the sewage tank. The sewage tank is an important part of the cleaning equipment, and the main function is to collect dry and wet garbage, and a pre-warning structure for detecting the liquid level is usually arranged inside. When the absorbed sewage reaches the pre-warning liquid level, the user is warned.

[0004] However, the cleaning equipment will be inclined or laid flat during work to clean corners such as under the bed and under the sofa. The liquid level of the above-mentioned sewage tank changes when it is inclined or laid flat, which is easy to produce false alarm and the user experience is poor. INVENTION CONTENTS

[0005] In order to solve at least one problem mentioned in the background, the present application provides a sewage tank, a cleaning equipment and a cleaning system, which aims to solve the technical problem that the liquid level of the sewage tank changes when it is inclined or laid flat, which is easy to produce false alarm and the user experience is poor in the related art.

[0006] In order to achieve the above-mentioned purpose, in a first aspect, the present application provides a sewage tank, comprising,

[0007] a tank body, the tank body has an opening and a sewage cavity for storing sewage, and the opening communicates with the sewage cavity;

[0008] an upper cover, the upper cover covers the opening;

[0009] a detection assembly located on one side of the upper cover facing the sewage cavity; the detection assembly at least includes a first detection piece and a second detection piece, the first detection piece includes a first fixed end and a first free end, and the second detection piece includes a second fixed end and a second free end;

[0010] The first fixed end and the second fixed end are both connected to the upper cover;

[0011] The first free end is away from the upper cover relative to the first fixed end, and the second free end is away from the upper cover relative to the second fixed end, and the first free end and the second free end are both located in the sewage cavity;

[0012] If the posture of the box changes, at least the position of the first free end changes relative to the box;

[0013] The detection assembly is further configured to electrically connect the first free end and the second free end by the liquid when the first free end contacts the liquid in the sewage cavity and the second free end contacts the liquid in the sewage cavity, so as to electrically connect the first detection piece and the second detection piece.

[0014] The sewage box provided in the application keeps the first free end in a vertical downward state under the action of gravity. When the posture of the box changes, the box drives the first fixed end to tilt, so that the position between the first free end and the first fixed end changes. With the change of the posture of the box, the liquid in the sewage cavity flows synchronously, and then the liquid level changes. The first free end that changes in position will first contact the liquid. With the increase of the volume of the liquid in the sewage box, the water level increases. When the second free end of the second detection piece contacts the liquid, the first free end and the second free end can form an electrical connection through the liquid. In this way, it is ensured that the two free ends will contact the liquid and form an electrical connection at the same time when the liquid level reaches a certain height, so as to trigger the liquid level alarm and reduce the possibility of false alarm.

[0015] From the above, the first free end of the detection assembly can change its position relative to the box when the device is tilted, so as to adapt to different body postures, so that the sewage box can accurately detect the liquid level in different working states. The liquid level state is judged by the conductivity of the liquid through the multiple detection pieces, which can effectively reduce the false alarm of liquid level detection caused by the tilting or lying of the body, and improve the accuracy of liquid level detection.

[0016] Secondly, by reducing false alarms and improving detection accuracy, users do not have to frequently deal with false alarms, thereby improving user experience and the convenience of using the cleaning device.

[0017] In addition, the liquid level is detected by the conductivity of the liquid, without the need for complex electronic sensors and circuit design, which can reduce manufacturing cost and failure rate, and improve the reliability of the cleaning device and the cleaning system.

[0018] Finally, since the detection assembly can respond to the change of the liquid level in real time, the user can obtain information about the state of the sewage box in time, which is convenient for cleaning and maintenance.

[0019] The sewage box provided in the application has a simple liquid level detection process, which can reduce unnecessary alarms and device downtime, thereby improving the overall energy efficiency of the cleaning device and the cleaning system, and meeting the trend of energy saving and environmental protection.

[0020] In the above sewage box, optionally, along the gravity direction of the box, the first free end is lower than the second free end;

[0021] The detection assembly is configured such that the first free end contacts the liquid in the sewage cavity earlier than the second free end.

[0022] Through the above configuration, hierarchical detection can be realized: the contact of the first free end as a pre-warning signal, and the contact of the second free end as a confirmation signal. In this way, false alarms caused by temporary liquid level fluctuations or tilting can be effectively filtered out, and an alarm will only be triggered when the liquid level continues to rise to a certain height.

[0023] In the sewage tank described above, optionally, the first detection member includes a deformation section, and the first free end and the first fixed end are respectively located near opposite ends of the deformation section; along the gravity direction of the tank body, the first free end is lower than the first fixed end.

[0024] The deformation section is configured to deform with changes in the attitude of the tank body to change the position of the first free end relative to the first fixed end.

[0025] Through the above arrangement, when the tank body is tilted or the attitude changes, the deformation section will deform under the action of force, causing the position of the first free end to change relative to the first fixed end, thereby enabling accurate detection of the liquid level under different attitudes, and further ensuring the effectiveness of the detection member under various working conditions.

[0026] In the sewage tank described above, optionally, the first free end and the first fixed end are respectively located at opposite ends of the deformation section.

[0027] Through the above arrangement, when the attitude of the tank body changes, the deformation section will deform according to the direction and size of the external force, thereby automatically adjusting the position of the first free end relative to the liquid surface, which can reduce false alarms caused by changes in the attitude of the tank body and improve the accuracy of liquid level detection.

[0028] In the sewage tank described above, optionally, the first detection member further includes a rigid section, the rigid section is connected with the deformation section, the first fixed end is located at one end of the rigid section away from the deformation section, and the first free end is located at one end of the deformation section away from the rigid section.

[0029] Through the above arrangement, the first fixed end is arranged at the end of the rigid section, which provides a stable connection point by utilizing the structural characteristics of the rigid section, preventing changes in the position of the fixed end caused by deformation of the deformation section, so that deformation of the deformation section does not affect the positioning of the first fixed end, thereby improving the overall stability of the first detection member. The first free end is arranged at the end of the deformation section, which can move freely under the deformation of the deformation section to adapt to changes in the liquid level and the tilting state of the tank body, thereby improving the sensitivity and accuracy of detection.

[0030] In the sewage tank described above, optionally, the first detection member further comprises a rotating shaft, the rotating shaft being located between the first free end and the first fixed end, and the first free end being rotationally connected to the first fixed end through the rotating shaft.

[0031] The first detection member is configured to rotate the first free end relative to the first fixed end to change the position of the first free end when the posture of the tank changes.

[0032] Through the above arrangement, when the posture of the tank changes, the first free end rotates relative to the first fixed end through the rotating shaft, thereby automatically adjusting the position of the first free end in the liquid. Through this automatic adjustment, the first detection member can maintain accurate detection of the liquid level under various body postures, reduce false alarms, and improve user experience.

[0033] In the sewage tank described above, optionally, the first free end is a gravity structure for conducting electricity.

[0034] The gravity structure is configured to move relative to the first fixed end under the action of gravity to change the position of the gravity structure relative to the tank when the posture of the tank changes, so that the gravity structure and the second free end successively contact the liquid in the sewage cavity, forming the first detection member and the second detection member electrically conductive.

[0035] Through the above arrangement, when the posture of the tank changes, the gravity structure can automatically adjust its position according to the change in the direction of gravity. This automatic adjustment capability ensures that the first free end can maintain accurate detection of the liquid level under different body postures. Through the action of gravity, the gravity structure can automatically move to a new equilibrium position when the device is tilted to ensure that it can timely contact the liquid.

[0036] The gravity structure and the second free end are designed to successively contact the liquid when the liquid level rises, ensuring that when the liquid level reaches a certain height, the two free ends will simultaneously contact the liquid and form a circuit conduction, thereby triggering a liquid level alarm and reducing false alarms.

[0037] In the sewage tank described above, optionally, when the first detection member comprises a deformation section, the deformation section is a chain.

[0038] The chain comprises a plurality of chain links, and adjacent two chain links are rotationally arranged and detachably connected.

[0039] By the above arrangement, the chain of multiple chain links can be flexibly adjusted in multiple directions, providing strong deformation capability, so that the first detection member can accurately detect the liquid level under various working states of the machine body. The modular design of the chain links allows the chain to be adjusted and configured as needed to adapt to different liquid level detection requirements. The combination of multiple chain links allows the chain to flexibly adjust its shape when subjected to external forces, thereby improving the accuracy of liquid level detection. The two adjacent chain links are rotatably arranged and detachably connected. The detachable design allows the chain to be quickly maintained and adjusted when needed to adapt to different detection requirements or replace damaged chain links.

[0040] In the above sewage tank, optionally, the gravity structure is a chain link, and the gravity structure is rotatably arranged and detachably connected with the deformation section.

[0041] By the above arrangement, the rotatable arrangement between the gravity structure and the deformation section allows the gravity structure to rotate and adjust relative to the deformation section when the machine body posture changes, to ensure that the gravity structure can respond to liquid level changes in time and maintain detection accuracy.

[0042] By allowing the gravity structure to rotate, the detection assembly can automatically adjust the position of the gravity structure in the liquid when the machine body posture changes, reducing false positives and improving the reliability of liquid level detection.

[0043] In addition, the detachable connection design allows the gravity structure and the deformation section to be easily maintained, adjusted or replaced, which can improve the maintainability and flexibility of the sewage tank, adapt to different detection requirements, and ensure the effectiveness and reliability of the sewage tank under various working conditions.

[0044] In the above sewage tank, optionally, the gravity structure is a metal structure; the deformation section includes at least one of a metal spring and a conductive structure;

[0045] The metal spring and the conductive structure are configured to deform under the action of the gravity of the gravity structure when the posture of the tank changes.

[0046] By the above arrangement, the metal material has good electrical conductivity and high density, so that the gravity structure can effectively conduct electricity and provide weight under the action of gravity to affect the deformation of the deformation section, thereby improving the sensitivity and reliability of liquid level detection.

[0047] When the posture of the tank changes, the gravity of the gravity structure causes the metal spring and the conductive structure to deform, thereby automatically adjusting the position of the free end. That is, the deformation section automatically adjusts its shape when the machine body posture changes to ensure that the first free end can accurately contact the liquid, thereby improving the accuracy of liquid level detection.

[0048] Through automatic adjustment, the deformation section can maintain accurate detection of the liquid level under different body postures, reduce false positives, and improve user experience.

[0049] In the sewage tank described above, optionally, the conductive structure is one of a conductive rubber structure, a graphene structure, and a carbon nanostructure.

[0050] Through the above arrangement, the conductive structure described above can maintain good conductivity during deformation, so that the first detection member can be flexibly adjusted when the body posture changes.

[0051] In a second aspect, the application also provides a cleaning device, comprising a body and a sewage tank, wherein the sewage tank is arranged on the body.

[0052] Through the above arrangement, by integrating the sewage tank on the body, the user is more convenient during use and maintenance, and in addition, the attitude distribution of the cleaning device can be optimized, and the stability and operation performance of the cleaning device can be improved.

[0053] In a third aspect, the application also provides a cleaning system, comprising a cleaning device and a base station or a base that cooperates with the cleaning device.

[0054] Through the above arrangement, the cleaning device is provided with the aforementioned sewage tank, which can accurately detect the liquid level under different working conditions. The cleaning device can reduce false positives and improve the accuracy of liquid level detection. Through cooperation with the cleaning device, the base station or the base can ensure the continuous availability of the device and simplify the user's operation process.

[0055] The structure of the application and its other application purposes and beneficial effects will be more obvious and easy to understand through the description of the preferred embodiments in conjunction with the drawings.

[0056] The sewage tank, cleaning device, and cleaning system provided by the embodiments of the application can accurately detect the liquid level when the body is inclined or lying down, reduce false positives, and improve the accuracy of detection through the detection assembly described above. The sewage tank can detect the liquid level by combining the conductivity of the liquid through multiple detection members, without complex design, which can reduce manufacturing cost and failure rate. In this way, the sewage tank can respond to liquid level changes in real time through the detection assembly, and the user can obtain information about the state of the sewage tank in a timely manner, facilitating cleaning and maintenance.

[0057] The cleaning device can effectively reduce false positives under different working conditions through the aforementioned sewage tank, so that the user does not have to frequently deal with false alarms, thereby improving user experience. By reducing false positives and improving detection accuracy, the overall reliability of the cleaning device is improved, ensuring that the cleaning device can work normally under various postures. The cleaning device has a simple liquid level detection process, which can reduce unnecessary alarms and device downtime, thereby improving the overall energy efficiency of the cleaning device, in line with the trend of energy saving and environmental protection.

[0058] The cleaning system can reduce the monitoring and manual intervention of the user on the cleaning device state by the automatic function of the base station or the base, and provide a more convenient cleaning experience. The cleaning device with the above-mentioned sewage tank can simplify the operation process of the user and improve the continuous availability of the cleaning system. In addition, the cleaning system using the foregoing cleaning device can reduce false positives and simplify the operation process, and the overall energy efficiency of the cleaning system is improved, thereby saving the time and effort of the user.

DETAILED DESCRIPTION

[0081] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in combination with the figures in the preferred embodiments of the present application. In the figures, the same or similar reference signs represent the same or similar device parts or device parts with the same or similar functions throughout. The described embodiments are part of device embodiments of the present application, not the whole device embodiments. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and cannot be understood as limiting the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present application. The embodiments of the present application will be described in detail below in combination with the figures.

[0082] In a first aspect, the embodiment of the present application provides a cleaning system (not shown in the figure), which comprises a base or a base station, and a cleaning device placed on the base or the base station.

[0083] It can be understood that after the cleaning device completes cleaning of the cleaning surface, it can be placed on the base or the base station for positioning, charging, self-cleaning, drying, or water supply and drainage. The base or the base station is provided with a placement position of the cleaning device, so that the positioning of the cleaning device can be realized. The base or the base station is provided with a charging interface, so that the charging of the cleaning device can be realized. The base station can be provided with a water inlet pipe and a sewage outlet pipe to supply water to the clean water tank of the cleaning device and drain water from the sewage tank 10. The base or the base station can be provided with a drying device for drying the cleaned cleaning device.

[0084] It should be noted that the base or the base station generally needs to be fixed on the ground to support the operation of the cleaning device.

[0085] In a second aspect, the embodiments of the present application also provide a cleaning device 20, which comprises a body 21 and a sewage tank 10, and the sewage tank 10 is arranged on the body 21.

[0086] It can be understood that the body 21 is suitable for performing a cleaning action on the surface A to be cleaned to achieve a cleaning effect. The surface A to be cleaned can be a ground, a wall surface with different roughness, or a carpet, a blanket, or a surface of an object to be cleaned with different lengths or different types, and the type of the surface A to be cleaned is not limited in the present application. The cleaning action can be a dust collection action, a mopping action, or a combination of the two to ensure the cleaning efficiency of the cleaning device 20.

[0087] Further, the body 21 can be connected to the sewage tank 10, and a sewage suction channel (not shown in the figure) can be arranged in the body 21, which is in communication with the sewage tank 10, so that external sewage can enter the sewage tank 10 under the action of negative pressure and be stored, thereby completing the cleaning work.

[0088] It should be noted that the cleaning device 20 can have different use angles during use. For example, Figure 1 The body 21 can be in a state perpendicular to the surface A to be cleaned; referring to Figure 2 The body 21 can be in a state intersecting with the surface A to be cleaned but not perpendicular; referring to Figure 3 The body 21 can be in a state parallel to the surface A to be cleaned. When the sewage tank 10 is connected to the body 21, the posture of the sewage tank 10 will be adjusted according to the state of the body 21. In the figure, B represents different use angles.

[0089] Referring to Figure 4 In a third aspect, the present application provides a sewage tank 10, which comprises a tank body 100, an upper cover 200, and a detection assembly 300.

[0090] Specifically, the box 100 has a sewage cavity 120 for storing sewage. The sewage cavity 120 can accommodate the substances sucked by the body 21. It should be noted that the substances sucked by the body 21 can include liquid, and can also include hair, dust, particles and other solids. Therefore, the box 100 can accommodate sewage and dirt.

[0091] It can be understood that the shape of the sewage tank 10 is matched with the shape of the body 21. For example, the shape of the sewage tank 10 can be a rectangular parallelepiped, can be a cylinder, can be a triangular cylinder, and the like. The specific shape of the sewage tank 10 is not limited in the embodiments of the present application, and is not limited to the above examples.

[0092] The specific structure of the box 100 is described below.

[0093] Referring to Figure 4 , the box 100 also has an opening 110, and the opening 110 communicates with the sewage cavity 120. The opening 110 is arranged at the edge position of the box 100, and is used to communicate the sewage cavity 120 with the external environment. It should be noted that the opening 110 can be arranged on the end face of the box 100, or can be arranged on the side wall of the box 100. The opening 110 on the box 100 is not limited in the embodiments of the present application, and is not limited to the above examples.

[0094] The opening 110 arranged on the end face of the box 100 is described below.

[0095] The upper cover 200 covers the opening 110. That is, the upper cover 200 can close the opening 110 to ensure the closure of the box 100.

[0096] It should be noted that the opening 110 can be located on the upper end face of the box 100, or can be located on the lower end face of the box 100.

[0097] It can be understood that the opening 110 can have various purposes. For example, the opening 110 can be used to dock the body 21, and the sewage and dirt sucked by the cleaning device 20 can enter the sewage cavity 120 through the opening 110. Another example, the opening 110 can also be used for sewage discharge, that is, the sewage and dirt in the sewage cavity 120 can be discharged through the opening 110. The position and function of the opening 110 are not limited in the embodiments of the present application, and are not limited to the above examples.

[0098] Referring to Figure 5 , the detection assembly 300 is located on the side of the upper cover 200 facing the sewage cavity 120. That is, the detection assembly 300 is located in the sewage cavity 120.

[0099] The detection assembly 300 at least includes a first detection piece 310 and a second detection piece 320, that is, the detection assembly 300 includes a plurality of detection pieces. The detection assembly 300 can detect the sewage level in the sewage cavity 120 through the plurality of detection pieces.

[0100] With reference to Figure 5 , the first detection piece 310 includes a first fixed end 311 and a first free end 312, and the second detection piece 320 includes a second fixed end 321 and a second free end 322. The free end refers to the position change in the sewage cavity 120. The fixed end refers to the position change in the sewage cavity 120.

[0101] It can be understood that when the free end can move in the sewage cavity 120, the detection piece can flexibly respond to the change of the liquid level in the sewage cavity 120. For example, the state of the machine body 21 changes, and the free end changes the position synchronously, thereby reflecting the real liquid level state.

[0102] With reference to Figure 5 , the first fixed end 311 and the second fixed end 321 are connected to the upper cover 200, and the first fixed end 311 is electrically connected to the second fixed end 321. The design of the electrical connection makes it possible to form a circuit conduction when the two free ends are contacted by the liquid, thereby providing a liquid level detection signal.

[0103] With reference to Figure 5 , the first free end 312 is away from the upper cover 200 relative to the first fixed end 311, and the second free end 322 is away from the upper cover 200 relative to the second fixed end 321. The first free end 312 and the second free end 322 are located in the sewage cavity 120. The free end is away from the upper cover 200 relative to the fixed end and is located in the sewage cavity 120. The relative position relationship between the free end and the fixed end can ensure that the free end can contact the liquid in the sewage cavity 120, thereby forming an electrical connection when the liquid level reaches a certain height.

[0104] If the posture of the box body 100 changes, at least the position of the first free end 312 changes relative to the box body 100. The position of the free end changes relative to the box body 100, and the detection assembly 300 can adapt to the inclination or movement of the box body 100, thereby reducing the false alarm caused by the change of the posture.

[0105] The detection assembly 300 is further configured to electrically connect the first free end 312 and the second free end 322 through the liquid when the first free end 312 contacts the liquid in the sewage cavity 120 and the second free end 322 contacts the liquid in the sewage cavity 120, so as to electrically connect the first detection piece 310 and the second detection piece 320.

[0106] It can be understood that the machine body 21 can be provided with an alarm device, and the alarm device can be electrically connected to the detection assembly 300.

[0107] Referring to Figure 6 When both free ends contact the liquid, the two free ends form an electrical connection through the liquid. In this way, it is ensured that both free ends contact the liquid and form an electrical connection at the same time when the liquid level reaches a certain height, thereby triggering the liquid level alarm and reducing the likelihood of false alarms.

[0108] The sewage tank 10 provided by the embodiments of the present application can effectively reduce false alarms of liquid level detection caused by tilting or lying of the machine body 21 and improve the accuracy of liquid level detection by setting multiple detection members and judging the liquid level state through the electrical conductivity of the liquid.

[0109] Secondly, by reducing false alarms and improving detection accuracy, users do not have to frequently deal with false alarms, thereby improving user experience and the use convenience of the cleaning device 20.

[0110] In addition, by detecting the liquid level through the electrical conductivity of the liquid, complex electronic sensors and circuit designs are not required, which can reduce manufacturing costs and failure rates and improve the reliability of the cleaning device 20 and the cleaning system.

[0111] Finally, since the detection assembly 300 can respond to liquid level changes in real time, users can obtain information about the state of the sewage tank 10 in a timely manner, which facilitates cleaning and maintenance. The sewage tank 10 provided by the embodiments of the present application has a simple liquid level detection process, which can reduce unnecessary alarms and device downtime, thereby improving the overall energy efficiency of the cleaning device 20 and the cleaning system and meeting the trend of energy saving and environmental protection.

[0112] Referring to Figures 6-11 As an optional implementation, the first free end 312 is lower than the second free end 322 in the direction of gravity G of the tank body 100.

[0113] It can be understood that when the liquid level in the sewage cavity 120 rises, the first free end 312 contacts the liquid first due to its lower position, thereby serving as a preliminary liquid contact point. When the liquid level continues to rise until the second free end 322 is contacted, the first free end 312 and the second free end 322 form a complete circuit conduction signal through the liquid.

[0114] In addition, when the first free end 312 contacts the liquid first, it can provide a buffer time for the contact of the second free end 322 to avoid false alarms caused by liquid shaking or temporary tilting.

[0115] The detection assembly 300 is configured such that the first free end 312 contacts the liquid in the sewage cavity 120 earlier than the second free end 322. That is, the first free end 312 contacts the liquid earlier than the second free end 322 during the rising of the liquid level.

[0116] When the liquid level gradually rises, the first free end 312, which is lower in position, will first contact the liquid. If the liquid level continues to rise and reaches the second free end 322, that is, the liquid level in the sewage cavity 120 reaches the warning level, an alarm signal can be triggered, forming double detection, which can improve the reliability and accuracy of liquid level detection.

[0117] Through the above configuration, hierarchical detection can be achieved: the contact of the first free end 312 as a pre-warning signal, and the contact of the second free end 322 as a confirmation signal. In this way, false alarms caused by temporary liquid level fluctuations or tilting can be effectively filtered out, and an alarm will only be triggered when the liquid level continues to rise to a certain height.

[0118] Referring to Figure 7 As an optional embodiment, the first detection member 310 includes a deformation section 313, and the first free end 312 and the first fixed end 311 are respectively located near opposite ends of the deformation section 313.

[0119] It can be understood that when the first detection member 310 is subjected to the action of gravity G, it will deform. This deformation enables the first free end 312 to maintain a relative position with the liquid surface when the machine body 21 is in different postures, thereby improving the accuracy of liquid level detection.

[0120] The deformation section 313 enables the first detection member 310 to have a certain flexibility and deformability. In this way, when the machine body 21 changes its posture, the deformation section 313 can deform, thereby adjusting the position of the first free end 312. This arrangement can enhance the flexibility of the detection member to adapt to different working states of the cleaning device 20.

[0121] In the direction of gravity G along the tank body 100, the first free end 312 is lower than the first fixed end 311. Since the first free end 312 is lower than the first fixed end 311, when the liquid level rises, the first free end 312 will first contact the liquid. In combination with the deformation section 313, this can automatically adjust the position of the first free end 312 when the machine body 21 is tilted, to ensure that it can always accurately detect changes in the liquid level.

[0122] The deformation section 313 is configured to deform with changes in the posture of the tank body 100 to change the position of the first free end 312 relative to the first fixed end 311.

[0123] When the box 100 is tilted or the posture changes, the deformation section 313 will be deformed by the force, so that the position of the first free end 312 changes relative to the first fixed end 311, thereby maintaining accurate detection of the liquid level in different postures, and ensuring the effectiveness of the detection member under various working conditions.

[0124] Through the above setting, the first detection member 310 automatically adjusts the position when the device posture changes to accurately detect the change of the liquid level, thereby reducing the false alarm caused by the change of the posture of the machine body 21, and improving the reliability and adaptability of the liquid level detection.

[0125] As an optional embodiment, the first free end 312 and the first fixed end 311 are respectively located at opposite ends of the deformation section 313. That is, the deformation section 313 connects the first free end 312 and the first fixed end 311 in the length direction of the deformation section 313. When the deformation section 313 is deformed under the action of gravity G, the position of the first free end 312 relative to the first fixed end 311 is changed.

[0126] Since the first free end 312 and the first fixed end 311 are respectively located at the two ends of the deformation section 313, when the deformation section 313 is subjected to gravity G, the deformation section 313 can be elongated, compressed or bent in the length direction. The deformation ability makes the first free end 312 adjust its position under different postures of the machine body 21. That is, when the posture of the machine body 21 changes, the deformation section 313 will be deformed according to the direction and size of the external force, so that the position of the first free end 312 is automatically adjusted relative to the liquid surface, which can reduce the false alarm caused by the change of the posture of the machine body 21, and improve the accuracy of the liquid level detection.

[0127] Referring to Figure 7 As an optional embodiment, the first detection member 310 further comprises a rigid section 314 connected with the deformation section 313. The first fixed end 311 is located at one end of the rigid section 314 away from the deformation section 313. That is, the first fixed end 311 is arranged at the end of the rigid section 314, which provides a stable connection point by using the structural characteristics of the rigid section 314, prevents the change of the position of the fixed end caused by the deformation of the deformation section 313, so that the deformation of the deformation section 313 does not affect the positioning of the first fixed end 311, thereby improving the overall stability of the first detection member 310.

[0128] The first free end 312 is located at one end of the deformation section 313 away from the rigid section 314. The first free end 312 is arranged at the end of the deformation section 313, which can move freely under the deformation of the deformation section 313 to adapt to the change of the liquid level and the tilting state of the machine body 21, thereby improving the sensitivity and accuracy of the detection.

[0129] Referring to Figure 8As an optional implementation, the first detection member 310 further comprises a rotating shaft 315 located between the first fixed end 311 and the first free end 312.

[0130] The rotating shaft 315 provides a rotational degree of freedom, so that the first free end 312 can rotate relative to the first fixed end 311 when the device posture changes, thereby adjusting its position in the liquid, so that the first detection member 310 can adapt to the posture change of the machine body 21.

[0131] The first free end 312 is rotatably connected to the first free end 312 through the rotating shaft 315. The rotational connection enables the first free end 312 to move flexibly under the action of the deformation section 313 without affecting the stability of the first fixed end 311, which can improve the flexibility and adaptability of the first detection member 310, thereby reducing false positives caused by posture changes.

[0132] The first detection member 310 is configured to rotate the first free end 312 relative to the first fixed end 311 to change the position of the first free end 312 when the posture of the box body 100 changes.

[0133] When the posture of the box body 100 changes, the first free end 312 rotates relative to the first fixed end 311 through the rotating shaft 315, thereby automatically adjusting the position of the first free end 312 in the liquid. Through this automatic adjustment, the first detection member 310 can maintain accurate detection of the liquid level under various machine body 21 postures, reduce false positives, and improve user experience.

[0134] Referring to Figure 9 As an optional implementation, the first free end 312 is a gravity structure 316 for conducting electricity.

[0135] By designing the first free end 312 as a gravity structure 316, the first free end 312 not only can conduct electricity, but also can use the action of gravity G to adjust its position, so that the first free end 312 can flexibly respond to the posture change of the machine body 21 in liquid level detection.

[0136] The gravity structure 316 is configured to move relative to the first fixed end 311 under the action of gravity when the posture of the box body 100 changes, to change the position of the gravity structure 316 relative to the box body 100, so that the gravity structure 316 and the second free end 322 successively contact the liquid in the sewage cavity 120, forming the first detection member 310 and the second detection member 320 electrically conductive.

[0137] That is, when the posture of the box 100 changes, the gravity structure 316 can automatically adjust its position according to the direction of the gravity G. This automatic adjustment capability ensures that the first free end 312 can maintain accurate detection of the liquid level under different postures of the fuselage 21. Under the action of the gravity G, the gravity structure 316 can automatically move to a new balance position when the device is tilted to ensure that it can timely contact the liquid.

[0138] The gravity structure 316 and the second free end 322 are designed to contact the liquid in sequence when the liquid level rises, ensuring that both free ends will contact the liquid and form a circuit conduction at the same time when the liquid level reaches a certain height, thereby triggering the liquid level alarm and reducing false alarms.

[0139] Referring to Figure 10 and Figure 11 , as an optional embodiment, when the first detection member 310 includes the deformation section 313, the deformation section 313 is a chain 317.

[0140] The chain 317 structure is composed of a plurality of chain links 318, which can flexibly bend and adjust in multiple directions, so that the first detection member 310 can adapt to different postures of the fuselage 21. The chain 317 structure provides high flexibility and deformability, so that the first detection member 310 can flexibly adjust its shape and position when the posture of the fuselage 21 changes, which helps to improve the accuracy of liquid level detection.

[0141] The chain 317 includes a plurality of chain links 318. The chain 317 with a plurality of chain links 318 can flexibly adjust in multiple directions, thereby providing strong deformation capability, so that the first detection member 310 can maintain accurate detection of the liquid level under various working states of the fuselage 21.

[0142] The modular design of the chain link 318 allows the chain 317 to be adjusted and configured as needed, such as increasing or reducing the number of chain links 318, to adapt to different liquid level detection requirements.

[0143] The combination of a plurality of chain links 318 allows the chain 317 to flexibly adjust its shape when subjected to external force, thereby improving the accuracy of liquid level detection.

[0144] The adjacent two chain links 318 are rotatably arranged and detachably connected. The detachable design allows the chain 317 to be quickly maintained and adjusted when needed to adapt to different detection requirements or replace damaged chain links 318.

[0145] Referring to Figure 6 , as an optional embodiment, the gravity structure 316 is a chain link 318, and the gravity structure 316 and the deformation section 313 are rotatably arranged and detachably connected.

[0146] As can be known from the foregoing, the chain ring 318 has high flexibility and deformability, so that the gravity structure 316 can freely bend and adjust in multiple directions.

[0147] The rotatable arrangement between the gravity structure 316 and the deformation section 313 enables the gravity structure 316 to rotate and adjust relative to the deformation section 313 when the body 21 changes in posture, so as to ensure that the gravity structure 316 can respond to the liquid level change in time and maintain the detection accuracy.

[0148] By allowing the gravity structure 316 to rotate, the detection assembly 300 can automatically adjust the position of the gravity structure 316 in the liquid when the body 21 changes in posture, reduce false positives, and improve the reliability of liquid level detection.

[0149] In addition, the detachable connection design enables the gravity structure 316 and the deformation section 313 to be conveniently maintained, adjusted, or replaced, which can improve the maintainability and flexibility of the sewage tank 10, adapt to different detection requirements, and thus ensure the effectiveness and reliability of the sewage tank 10 under various working conditions.

[0150] As an optional implementation, the gravity structure 316 is a metal structure. That is, the gravity structure 316 is made of a metal material. The metal material has good electrical conductivity and high density, so that the gravity structure 316 can effectively conduct electricity and provide weight under the action of gravity G to affect the deformation of the deformation section 313, thereby improving the sensitivity and reliability of liquid level detection.

[0151] The deformation section 313 includes at least one of a metal spring and a conductive structure. That is, the deformation section 313 can be a metal spring, a conductive structure, or both.

[0152] Referring to Figure 9 The metal spring can provide elastic deformation capability while providing electrical conductivity.

[0153] The conductive structure can ensure the conductivity of the circuit.

[0154] When the deformation section 313 includes a metal spring and a conductive structure, the deformation section 313 can flexibly adjust under the action of gravity G while maintaining the integrity of the circuit.

[0155] The metal spring and the conductive structure are both configured to deform under the action of gravity G of the gravity structure 316 when the posture of the tank 100 changes. When the posture of the tank 100 changes, the gravity G exerted by the gravity structure 316 causes the metal spring and the conductive structure to deform, thereby automatically adjusting the position of the free end. That is, the deformation section 313 automatically adjusts its shape when the body 21 changes in posture, so as to ensure that the first free end 312 can accurately contact the liquid, thereby improving the accuracy of liquid level detection.

[0156] Through automatic adjustment, the deformation section 313 can maintain accurate detection of the liquid level at different body 21 postures, reduce false positives, and improve user experience.

[0157] As an optional implementation, the conductive structure is one of a conductive rubber structure, a graphene structure, and a carbon nanostructure.

[0158] It can be understood that conductive rubber is a flexible material with good electrical conductivity and elasticity. The flexibility and elasticity of conductive rubber enable it to maintain good electrical conductivity during deformation, while adapting to complex geometries and dynamic changes, so that the first detection member 310 can be flexibly adjusted when the body 21 posture changes.

[0159] Graphene is a two-dimensional material arranged by single-layer carbon atoms, with excellent electrical conductivity and mechanical strength. The high electrical conductivity and strength of graphene enable it to provide strong current conduction capability in a relatively thin structure while maintaining the integrity of the structure, so that the first detection member 310 can provide fast and accurate signal response in liquid level detection.

[0160] Carbon nanostructures include carbon nanotubes and other nanoscale carbon materials, with excellent electrical conductivity and mechanical properties. The high electrical conductivity and flexibility of carbon nanostructures enable them to provide stable current conduction during deformation while adapting to complex deformation requirements, so that the first detection member 310 can maintain efficient liquid level detection in dynamic environments.

[0161] Referring to Figure 12 It can be understood that the structure of the second detection member 320 can be the same as or different from that of the first detection member 310. Based on the first detection member 310 described above, the structure of the second detection member 320 can be combined with that of the first detection member 310 in any way, and both can form adaptive detection of the liquid level.

[0162] It should be noted that the number and position of the first detection member 310 and the second detection member 320 can be adjusted according to actual conditions, and the present application embodiment does not repeat the description.
