Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a top-out mechanism, cleaning equipment, base station, and cleaning system. Background Technology

[0002] With the increasing popularity of smart cleaning equipment (such as robot vacuums and floor scrubbers), base station systems with automatic sewage discharge functions have become a key configuration for improving user experience.

[0003] In existing technologies, base stations typically need to actively drive the sewage tank's discharge port to open.

[0004] However, the above solution requires the base station to be equipped with a drive mechanism, which is complex in structure and has a high manufacturing cost. Summary of the Invention

[0005] This application provides an ejection mechanism, cleaning equipment, base station, and cleaning system, which can solve the technical problems of existing base stations requiring a drive mechanism, resulting in complex structures and high manufacturing costs.

[0006] In a first aspect, embodiments of this application provide an ejection mechanism for a cleaning device having a wastewater tank and a cleaning component, wherein the cleaning component is movable outward relative to the body of the cleaning device, and the wastewater tank has a drain outlet and a switch for opening or closing the drain outlet.

[0007] The ejection mechanism includes:

[0008] case;

[0009] A push rod assembly is movably disposed in the housing, the push rod assembly having at least two linked movable ends, wherein the two movable ends are respectively used to correspond to the switch and the cleaning component; the push rod assembly has an extended state;

[0010] When the cleaning component moves outward relative to the body, the cleaning component abuts against the movable end of the corresponding cleaning component, and drives the movable end of the corresponding cleaning component to move closer to the housing, so that the push rod assembly is in the ejected state;

[0011] When the push rod assembly is in the ejected state, the movable end of the corresponding switch moves away from the housing to trigger the switch and open the drain port.

[0012] The ejection mechanism provided in this application embodiment allows the cleaning component to move outward relative to the main body when the cleaning equipment returns to the base station after completing its cleaning task. The cleaning component then abuts against the movable end of the corresponding cleaning component in the ejection mechanism, pushing that movable end back into the housing, while simultaneously causing the other movable end to extend outward. The movable end moving towards the main body abuts against a switch, causing the switch to open the drain port, thus discharging wastewater from the wastewater tank.

[0013] The above process does not require additional power components in the base station. It relies solely on the structural movement of the cleaning equipment itself and the coordination of the ejection mechanism to complete the sewage discharge action. This eliminates the possibility of sewage discharge failure due to motor failure, control malfunction, or environmental interference. It solves the problems of complex structure, high cost, and low reliability in the background technology and achieves the technical effect of low cost, high stability, and easy maintenance.

[0014] As an optional implementation, the push rod assembly includes:

[0015] The first push rod and the second push rod are both slidably disposed on the housing. The first push rod corresponds to the switch of the sewage tank, and the second push rod corresponds to the cleaning component. When the ejection mechanism is in the ejection state, the second push rod moves closer to the housing.

[0016] A connecting rod is located inside the housing, the connecting rod is connected between the first push rod and the second push rod, and is rotatably connected to the housing;

[0017] The connecting rod is configured to rotate synchronously when the second push rod moves closer to the housing, and to drive the first push rod away from the housing.

[0018] With the above-described configuration, this embodiment eliminates the need for a power unit in the base station, reducing its complexity and manufacturing cost. Furthermore, the movements of the cleaning components and the ejection mechanism are transmitted mechanically without signal transmission, thus eliminating signal delay and improving the synchronization of self-cleaning, thereby enhancing the stability of the cleaning system. Simultaneously, the absence of short circuits ensures the normal operation of the cleaning equipment, base station, and cleaning system, thereby improving the user experience.

[0019] As an optional implementation, the housing has a guide hole extending in a straight direction;

[0020] At least one of the first push rod and the second push rod is slidably connected to the end of the connecting rod, so that at least one of the first push rod and the second push rod moves through the guide hole along the straight direction.

[0021] With the above settings, the linearly extending guide hole and the sliding connection can constrain the movement trajectory of at least one push rod, improve the movement stability of the first push rod and the second push rod, reduce the possibility of the trigger being accidentally touched or not being triggered, ensure that sewage discharge is accurately triggered, and thus ensure the stable operation of the cleaning equipment and improve the user experience.

[0022] As an optional implementation, the connecting rod is rotatably connected to the housing via a rotating shaft;

[0023] The connecting rod has sliding grooves formed at both ends, and the sliding grooves extend along the length direction of the connecting rod; the end of the first push rod near the rotating shaft and the end of the second push rod near the rotating shaft are respectively provided with sliders corresponding to the sliding grooves, and the sliders can slide along the length direction within the sliding grooves;

[0024] or,

[0025] The first push rod and the second push rod, both near the shaft, have sliding grooves that extend along the length of the connecting rod. Both ends of the connecting rod are provided with sliders corresponding to the sliding grooves, which can slide along the length of the sliding grooves.

[0026] With the above configuration, the first push rod and the second push rod can slide along the length of the connecting rod to ensure that the linear and sliding movements of the first and second push rods can coordinate with the rotation of the connecting rod, thereby ensuring the linkage between the first and second push rods.

[0027] As an optional implementation, it also includes an elastic element disposed between the push rod assembly and the housing; the push-out mechanism also has an initial state;

[0028] When the ejection mechanism is in the initial state, the elastic element is in the released state, the movable end of the cleaning component moves away from the housing and the movable end of the switch moves closer to the housing;

[0029] The elastic element is configured to contract during the transition of the push rod assembly from the initial state to the ejected state, and to release during the transition of the push rod assembly from the ejected state to the initial state.

[0030] The ejector mechanism, cleaning equipment, base station, and cleaning system provided in this application embodiment achieve automatic reset of the ejector mechanism under conditions without external drive. By setting an elastic element, the ejector mechanism is synchronously reset when the cleaning component is reset; and in conjunction with the aforementioned second torsion spring and spring release, it drives the sewage tank switch to reset and close the sewage outlet.

[0031] The above process is completed by a mechanical structure, eliminating the need for a power unit in the base station and reducing its complexity and manufacturing cost. Furthermore, the movements of the cleaning components and the ejection mechanism are transmitted mechanically without signal transmission, thus eliminating signal delay and improving the synchronization of self-cleaning, thereby enhancing the stability of the cleaning system.

[0032] In addition, the reset of the elastic element can improve the reliability and consistency of sewage control, ensuring that the ejection mechanism and cleaning equipment can be repeated multiple times, so as to ensure the normal operation of the cleaning equipment, base station and cleaning system, thereby improving the user experience.

[0033] As an optional implementation, when the push rod assembly includes a first push rod, a second push rod, and a connecting rod, a rotating shaft is provided inside the housing, and the connecting rod has a through hole corresponding to the rotating shaft. The connecting rod is sleeved on the rotating shaft through the through hole to rotate relative to the housing.

[0034] The elastic element is a first torsion spring, which is sleeved on the rotating shaft; one end of the first torsion spring abuts against the first push rod or a portion of the connecting rod near the first push rod, and the other end of the first torsion spring abuts against the housing.

[0035] With the above configuration, the rotating shaft simultaneously serves as both a rotation fulcrum and a torsion spring mounting shaft, improving the space utilization within the housing. This allows the ejection mechanism to occupy a smaller volume within the base station, thus providing sufficient cleaning space for the cleaning equipment to ensure its self-cleaning function.

[0036] Secondly, this application also provides a cleaning device, including a body and a wastewater tank, cleaning components and the ejection mechanism located on the body;

[0037] The cleaning component is rotatably connected to the body and can move away from or towards the housing along the axial direction of the cleaning component;

[0038] The wastewater tank includes a tank body, the tank body having a wastewater cavity for storing wastewater and a drain outlet communicating with the wastewater cavity;

[0039] The sewage tank also includes a switch corresponding to the sewage outlet. The switch is located on the outside of the tank and is rotatably connected to the tank to open or close the sewage outlet.

[0040] The ejection mechanism is located on the side of the machine body and corresponds to the cleaning component and the wastewater tank.

[0041] With the above setup, the sewage discharge of the cleaning equipment does not need to be coordinated with the base station. In this way, sewage discharge does not need to be carried out inside the base station and can be carried out at any time according to the user's needs, which can be achieved simply by moving the cleaning components.

[0042] Thirdly, this application embodiment also provides a base station, including a base station body and the aforementioned ejection mechanism;

[0043] The base station body has a receiving cavity for docking cleaning equipment, and the ejection mechanism is located on the cavity wall of the receiving cavity.

[0044] With the above configuration, when the cleaning equipment is located within the receiving cavity, the base station can clean the cleaning components on the cleaning equipment; simultaneously, the cleaning components can move outward to open the drain box via the ejection mechanism, enabling simultaneous draining and cleaning of the cleaning components. This saves time on the self-cleaning of the cleaning equipment, increasing its operating frequency and reducing noise from self-cleaning, thus improving the user experience.

[0045] Thirdly, embodiments of this application also provide a cleaning system, including the cleaning equipment or the base station;

[0046] When the cleaning equipment includes an ejection mechanism, the cleaning system further includes a base station corresponding to the cleaning equipment, the base station having a receiving cavity for docking with the cleaning equipment;

[0047] When the base station includes the ejection mechanism, the cleaning system also includes cleaning equipment, which includes a body and a wastewater tank and cleaning components located on the body;

[0048] The cleaning component is rotatably connected to the body and can move toward the outside of the body (100);

[0049] The wastewater tank includes a tank body, the tank body having a wastewater cavity for storing wastewater and a drain outlet communicating with the wastewater cavity;

[0050] The sewage tank also includes a switch corresponding to the sewage outlet. The switch is located on the outside of the tank and is rotatably connected to the tank to open or close the sewage outlet.

[0051] With the above settings, the cleaning system provided in this application embodiment can reduce manufacturing costs and the possibility of short circuits. Even if short circuits are possible, the normal operation of the cleaning equipment, base station, and cleaning system can be guaranteed, thereby improving the user experience.

[0052] As an optional implementation, when the base station includes the ejection mechanism and the ejector assembly includes a first ejector, a second ejector, and a connecting rod,

[0053] The two ends of the switch are a blocking part and a triggering part, respectively. The blocking part is used to block the drain outlet, and the triggering part is used to correspond to the first push rod.

[0054] The switch is rotatably connected to the housing via a rotating shaft. A second torsion spring is sleeved on the rotating shaft. In the axial direction intersecting the rotating shaft, the blocking part and the triggering part are located on opposite sides of the rotating shaft.

[0055] With the above settings, the switch can automatically close the drain outlet after the cleaning component is reset, without the need for an additional structure to drive the switch to close, thus reducing costs. The resettable switch also has a certain leak-proof function, which can improve the sealing performance of the sewage tank, reduce the possibility of sewage tank leakage, and improve the user experience.

[0056] As an optional implementation, when the base station includes the ejector mechanism,

[0057] The fuselage has an assembly cavity corresponding to the sewage tank, and the sewage tank is located in the assembly cavity;

[0058] The body also has a trigger hole corresponding to the trigger part, and the trigger hole is connected to the outside of the body;

[0059] The body also includes an ejector, which is fitted with a spring and is slidably disposed in the assembly cavity by means of the spring;

[0060] When the movable end of the corresponding switch moves toward the housing, the ejector moves toward the trigger part to compress the spring until the trigger part is triggered, and the second torsion spring is contracted to open the drain port;

[0061] When the movable end of the corresponding switch moves away from the housing, the spring releases, causing the ejector to move away from the trigger until the trigger is released, at which point the second torsion spring is released to close the drain port.

[0062] By incorporating a spring, the impact from the movement of the ejector component can be mitigated, thus protecting the triggering part. Furthermore, there's no need for an additional structure to drive the switch to close, resulting in lower costs. The resettable switch also provides some leak-proof functionality, improving the sewage tank's sealing performance, reducing the possibility of leakage, and enhancing the user experience.

[0086] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0087] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0088] Reference Figure 1 In a first aspect, embodiments of this application provide a cleaning system (not shown in the figures), including a cleaning device 10 and a base station. The cleaning device 10 can be placed on the base station.

[0089] The cleaning equipment 10 can be a floor scrubber, vacuum cleaner, sweeping robot, mopping robot, or a combined sweeping and mopping robot. In this embodiment, the cleaning equipment 10 is a robot with mopping function, such as a mopping robot or a combined sweeping and mopping robot.

[0090] Secondly, embodiments of this application also provide a base station. The base station includes a base station body (not shown in the figure), which is used to interface with the cleaning equipment 10.

[0091] After cleaning the surface to be cleaned, the cleaning device 10 can be placed on the base station for positioning, charging, self-cleaning, drying, or water supply and drainage. The base station has a designated placement location for the cleaning device 10, enabling its precise placement. The base station also has a charging interface for charging the cleaning device 10. The base station may be equipped with a water inlet pipe and a wastewater outlet pipe to fill the clean water tank of the cleaning device 10 and drain the wastewater tank 200. The base station may also include a drying device for drying the cleaned cleaning device 10.

[0092] In some embodiments, the base station body has a receiving cavity (not shown). The cleaning device 10 can be moved into the base station body such that the cleaning component 300 can be located within the receiving cavity.

[0093] It is understood that a nozzle (not shown in the figure) for spraying water toward the cleaning component 300 can be provided inside the receiving cavity to clean the cleaning component 300. Simultaneously, the cleaning component 300 can rotate to facilitate cleaning. This application does not limit the specific implementation of the base station cleaning device 10, nor is it limited to the above embodiments.

[0094] It should be noted that base stations generally need to be fixed to the surface to be cleaned in order to support the operation of the cleaning equipment.

[0095] Reference Figure 1 Thirdly, embodiments of this application also provide a cleaning device 10, which includes a body 100 and a wastewater tank 200 and a cleaning component 300 located on the body 100.

[0096] It is understood that the cleaning component 300 is suitable for performing cleaning actions on the surface to be cleaned to achieve a cleaning effect. The surface to be cleaned can be a surface with different roughness, a wall surface, or a carpet or blanket of different lengths or types, or the surface of an object to be cleaned. This application does not specifically limit the type of surface to be cleaned. The cleaning action can be a vacuuming action, a mopping action, or both vacuuming and mopping actions can be performed simultaneously to ensure the cleaning efficiency of the cleaning device 10.

[0097] The cleaning component 300 is rotatably connected to the machine body 100. It should be noted that the cleaning component 300 can be of various types, including but not limited to rollers, brush rollers, belts, mops, etc., all of which can clean the surface to be cleaned. This application embodiment does not limit the specific type of the cleaning component 300; the following example uses a roller as an example.

[0098] Reference Figure 2In some embodiments, the sewage tank 200 has a sewage chamber (not shown) for storing sewage and a drain outlet 201 for discharging sewage.

[0099] It is understandable that the shape of the drain outlet 201 can be arbitrary, such as a circular hole, a square hole, a triangular hole, or other shapes of holes, which can be selected according to actual needs.

[0100] Reference Figure 2 and Figure 3 In some embodiments, the sewage tank 200 also includes a switch 210 corresponding to the sewage outlet 201. The switch 210 is located on the outside of the tank and is rotatably connected to the tank to open or close the sewage outlet 201.

[0101] When switch 210 is turned on, there is an angle between switch 210 and drain outlet 201, so that drain outlet 201 is connected to the outside of the tank; when switch 210 is turned off, switch 210 can cover drain outlet 201, thereby sealing the sewage tank 200.

[0102] In related technologies, after the cleaning device 10 completes its cleaning task, it moves to the receiving cavity of the base station, where the base station can clean the cleaning components 300 of the cleaning device 10. Simultaneously, the base station is equipped with a corresponding opening device for the wastewater tank 200. When the cleaning device 10 is detected to be inside the receiving cavity, the opening device operates and opens the switch 210 of the wastewater tank 200, thereby opening the wastewater tank 200 and allowing the cleaning device 10 to discharge wastewater, facilitating its next cleaning task.

[0103] However, the above solution requires the installation of an opening device inside the base station, and the opening device requires additional power to drive it, resulting in higher costs for the base station and the cleaning system.

[0104] In addition, the main body of sewage discharge in sewage tank 200 is liquid, and the power drive is usually electric. Discharging sewage through electric drive may cause a short circuit, which may affect the normal operation of cleaning equipment 10, base station and cleaning system, and affect the user experience.

[0105] In some embodiments, the cleaning component 300 and the wastewater tank 200 are located at different positions on the main body 100. Generally, when the cleaning device 10 moves forward along a preset travel direction, the cleaning component 300 is located in front of the wastewater tank 200, and the wastewater tank 200 is located behind the main body 100. The preset travel direction refers to the travel direction of the cleaning device 10.

[0106] Furthermore, the body 100 is typically cylindrical, therefore the wastewater tank 200 is located closer to the edge of the body 100 than the cleaning components 300.

[0107] Reference Figure 2 Furthermore, to ensure smooth drainage of the drain outlet 201, the drain outlet 201 is typically formed at the bottom of the side of the tank. Therefore, the blocking part 211 of the switch 210 is located at the bottom of the wastewater tank 200, and correspondingly, the trigger part 212 is located above the blocking part 211. In some embodiments, the trigger part 212 is higher than the cleaning assembly 300 to facilitate smooth drainage.

[0108] In view of this, in a fourth aspect, embodiments of this application also provide an ejection mechanism 20 for use with the cleaning device 10.

[0109] Reference Figure 4 In some embodiments, the cleaning component 300 is movably configured. This movability includes, but is not limited to, sliding and rotating. As described above, the cleaning component 300 can rotate relative to the body 100. Furthermore, the cleaning component 300 can also move relative to the body 100. For example, the cleaning component 300 can move away from or towards the housing 400.

[0110] Reference Figure 4 In some embodiments, when the cleaning component 300 includes a roller, the roller can move outward relative to the body 100 and return to its original position after moving, i.e., the roller can reciprocate. In this way, the roller can expand outward to clean areas such as dead corners, which can increase the cleanable area of ​​the cleaning component 300, improve the cleaning effect of the cleaning device 10, and thus improve the user experience.

[0111] It is understandable that the direction of roller movement can be arbitrary. For example, the roller can move along its axial direction, its radial direction, or other directions. By setting a roller that moves axially, the rotation and movement of the roller can be independent of each other and will not affect each other. For example, the movement of the roller can be achieved by a drive structure that controls the rotation of the roller, and the space occupied is small. That is, in the axial direction of the roller, the roller can move relative to the machine body 100.

[0112] It should be noted that the movement of the cleaning component 300 is accomplished by the driving mechanism of the cleaning device 10 itself, without the need for the base station to provide power, and thus there is no need to set up a corresponding power unit in the base station, which can reduce the manufacturing cost of the base station.

[0113] Reference Figure 1 , Figure 4 Specifically, the ejection mechanism 20 includes a housing 400 and an ejector assembly 500. The ejector assembly 500 is movably disposed within the housing 400.

[0114] The housing 400 is used to mount the push rod assembly 500. The push rod assembly 500 has at least two linked movable ends 501.

[0115] It is understandable that the interconnected moving ends 501 refer to those with a definite kinematic relationship under mechanical constraints, such as rotation or movement, and the displacement direction and stroke of different moving ends 501 can be controlled. Examples include lever mechanisms, crank-connecting rod mechanisms, chain mechanisms, ratchet mechanisms, and belt mechanisms.

[0116] It should be noted that the specific linkage of the active terminal 501 in this embodiment is not limited, nor is it limited to the above example.

[0117] In some embodiments, two movable ends 501 of the push rod assembly 500 correspond to the switch 210 and the cleaning assembly 300, respectively.

[0118] It should be noted that the number of active terminals 501 can be arbitrary, such as two, three, four, etc. The specific number of active terminals 501 in this application embodiment is not limited, nor is it limited to the above example. It should be noted that the number of active terminals 501 is not less than two, to correspond to the aforementioned switch 210 and cleaning component 300.

[0119] Reference Figure 4 In some embodiments, the push rod assembly 500 has an extended state. When the cleaning component 300 is active, the cleaning component 300 abuts against the corresponding movable end 501 of the cleaning component 300, and drives the movable end 501 of the corresponding cleaning component 300 to move closer to the housing 400, so that the push rod assembly 500 is in the extended state. Specifically, the cleaning component 300 (such as a roller) moves outward relative to the machine body 100 along its axial direction. During this movement, the cleaning component 300 abuts against the corresponding movable end 501 of the cleaning component 300. Then, driven by the cleaning component 300, the movable end 501 moves closer to the housing 400 as the cleaning component 300 moves, so that the push rod assembly 500 is in the extended state.

[0120] It is understandable that the housing 400 is located outside the body 100, and the cleaning component 300 is located inside the body 100. When the cleaning component 300 moves outward relative to the body 100, the cleaning component 300 will move towards the housing 400 in sync.

[0121] As can be seen from the foregoing, the other movable end 501 of the top rod assembly 500 corresponds to the switch 210, and this movable end 501 is linked with the movable end 501 of the corresponding cleaning assembly 300.

[0122] Reference Figure 1 , Figure 4 In some embodiments, the moving direction of the active end 501 of the corresponding switch 210 is different from that of the active end 501 of the corresponding cleaning component 300.

[0123] It is understood that different directions may include, but are not limited to, opposite directions or an angle between the two directions. For example, when the movable end 501 of the corresponding roller moves away from the machine body 100 along the roller's axial direction, the movable end 501 of the corresponding switch 210 can move closer to the machine body 100 along the roller's axial direction. Another example is that when the movable end 501 of the corresponding roller moves away from the machine body 100 along the roller's axial direction, the movable end 501 of the corresponding switch 210 can move at an angle along the roller's radial direction.

[0124] The embodiments of this application do not limit the specific moving direction of different active terminals 501, nor are they limited to the above examples.

[0125] Reference Figure 2 Therefore, when the push rod assembly 500 is in the pushed-out state, the active end 501 of the corresponding switch 210 moves away from the housing 400 to trigger the switch 210 and open the drain port 201 to realize the discharge of sewage from the sewage tank 200.

[0126] The specific process is as follows:

[0127] Reference Figure 3 , Figure 4 When the cleaning equipment 10 returns to the base station after completing the cleaning task, the cleaning component 300 can move outward relative to the body 100. The cleaning component 300 abuts against the movable end 501 of the corresponding cleaning component 300 in the ejection mechanism 20, and pushes the movable end 501 to retract into the housing 400, so that the other movable end 501 extends outward simultaneously. The movable end 501 moving towards the body 100 abuts against the switch 210, and drives the switch 210 to open the drain port 201, realizing the discharge of sewage from the sewage tank 200.

[0128] The above process requires no additional power components at the base station; the sewage discharge is completed solely through the structural movement of the cleaning equipment 10 and the coordination of the ejection mechanism 20, eliminating the possibility of discharge failure due to motor malfunction, control failure, or environmental interference. Simultaneously, it solves the problems of complex structure, high cost, and low reliability in related technologies, achieving a low-cost, highly stable, and easily maintainable technical effect.

[0129] Reference Figure 2 , Figure 3 In some embodiments, the two ends of the switch 210 are a blocking part 211 and a trigger part 212, respectively. The blocking part 211 is used to block the drain outlet 201, and the trigger part 212 is used to trigger and drive the blocking part 211. The switch 210 is rotatably connected to the housing via a rotating shaft 213. In the axial direction intersecting the rotating shaft 213, the blocking part 211 and the trigger part 212 are located on opposite sides of the rotating shaft 213. That is, when the trigger part 212 rotates, the blocking part 211 rotates, so that the blocking part 211 opens or closes the drain outlet 201.

[0130] It should be noted that when the triggering part 212 is triggered, the angle at which the triggering part 212 rotates can be arbitrary, and the blocking part 211 can open the drain port 201. In order to ensure the drainage efficiency of the drain port 201, the rotation angle of the blocking part 211 can be as large as possible so that the drain port 201 is fully exposed.

[0131] Reference Figure 3 , Figure 4 As can be seen from the above, when the push rod assembly 500 is in the push-out state, the movable end 501 of the corresponding switch 210 moves away from the housing 400 (i.e. moves toward the body 100). The movable end 501 abuts against the trigger part 212 and drives the trigger part 212 to rotate relative to the rotating shaft 213, thereby driving the blocking part 211 to rotate synchronously, so that the blocking part 211 opens the drain port 201.

[0132] Reference Figure 4 In some embodiments, the rotating shaft 213 is fitted with a second torsion spring 214.

[0133] Reference Figure 3 , Figure 4 When the movable end 501 abuts against the trigger part 212, causing the trigger part 212 to rotate relative to the rotating shaft 213, the second torsion spring 214 is compressed. (Refer to...) Figure 1 , Figure 2 After the cleaning device 10 completes the sewage discharge, the cleaning component 300 resets, the second torsion spring 214 releases the stored elastic potential energy, and drives the switch 210 to rotate in the opposite direction until the shielding part 211 presses the sewage outlet 201 again to complete the closure.

[0134] With the above settings, the switch 210 can automatically close the drain port 201 after the cleaning component 300 is reset, without the need for additional structure to drive the switch 210 to close, thus reducing costs; the resettable switch 210 has a certain leak-proof function, which can improve the sealing performance of the sewage tank 200, reduce the possibility of leakage from the sewage tank 200, and improve the user experience.

[0135] As an optional implementation, the ejection mechanism 20 can be installed on the cleaning device 10 or on the base station.

[0136] Reference Figure 5 For example, when the ejector mechanism 20 is located on the cleaning device 10, the ejector mechanism 20 may be located on the side of the body 100 and correspond to the cleaning component 300 and the wastewater tank 200.

[0137] With the above settings, the sewage discharge of the cleaning device 10 does not need to be coordinated with the base station. In this way, sewage discharge does not need to be carried out inside the base station and can be carried out at any time according to the user's needs, which can be achieved simply by using the mobile cleaning component 300.

[0138] In another example, when the ejector mechanism 20 is located on the base station, the ejector mechanism 20 is located on the cavity wall of the receiving cavity.

[0139] With the above configuration, when the cleaning device 10 is located within the receiving cavity, the base station can clean the cleaning component 300 on the cleaning device 10; simultaneously, the cleaning component 300 can move outward to open the drain box via the ejection mechanism 20, enabling simultaneous draining and cleaning of the cleaning component 300. This saves time on the self-cleaning of the cleaning device 10, increasing its operating frequency and reducing noise from self-cleaning, thus improving the user experience.

[0140] It is understandable that whether the ejector mechanism 20 is installed on the cleaning equipment 10 or on the base station, it can solve the technical problems in the related technologies, such as the high cost of the base station and the cleaning system, the possibility of short circuits, which may affect the normal operation of the cleaning equipment 10, the base station and the cleaning system, and reduce the user experience.

[0141] With the above settings, the cleaning system provided in this application embodiment can reduce manufacturing costs and the possibility of short circuits. Even if a short circuit is possible, it can ensure the normal operation of the cleaning equipment 10, the base station, and the cleaning system, thereby improving the user experience.

[0142] Reference Figure 1 , Figure 4 The following explanation takes the example of the top-out mechanism 20 being located on the base station, that is, the base station includes the top-out mechanism 20.

[0143] Reference Figure 1 , Figure 4 In some embodiments, when the base station includes the ejector mechanism 20, the body 100 also has an assembly cavity 101 corresponding to the wastewater tank 200, with the wastewater tank 200 located inside the assembly cavity 101. That is, the wastewater tank 200 is located inside the body 100 to protect the wastewater tank 200.

[0144] The body 100 also has a trigger hole (not shown in the figure) corresponding to the trigger part 212, which is connected to the outside of the body 100. It can be understood that the trigger hole allows the movable end 501 of the cleaning component 300 to pass through, thereby entering the assembly cavity 101 and triggering the trigger part 212.

[0145] In some embodiments, to reduce the travel distance of the active end 501, the process of triggering the triggering unit 212 is accelerated. (Refer to...) Figure 2 , Figure 3 The body 100 also includes an ejector 110, which has a trigger hole through it. That is, the ejector 110 is located between the movable end 501 and the trigger part 212.

[0146] Reference Figure 3 , Figure 4 When the cleaning component 300 moves outward to abut against and drive the movable end 501 of the ejector mechanism 20 to move closer to the housing 400, the movable end 501 of the corresponding switch 210 moves closer to the body 100, abutting against and driving the ejector 110 to move away from the housing 400, until the ejector 110 abuts against the trigger part 212. The trigger part 212 rotates under the action of the ejector 110, thereby opening the drain port 201 and realizing the discharge of sewage from the sewage tank 200.

[0147] Reference Figure 3 , Figure 4 In some embodiments, the ejector 110 is fitted with a spring 120, and the ejector 110 is slidably disposed in the assembly cavity 101 by means of the spring 120.

[0148] Reference Figure 3 , Figure 4 When the movable end 501 of the corresponding switch 210 moves toward the housing 400, the ejector 110 moves closer to the trigger part 212, compressing the spring 120 until the trigger part 212 is triggered. The second torsion spring 214 is then contracted to open the drain port 201. (Refer to...) Figure 1 , Figure 2 When the movable end 501 of the corresponding switch 210 moves away from the housing 400, the spring 120 is released, causing the ejector 110 to move away from the trigger part 212 until the trigger part 212 is released, and the second torsion spring 214 is released to close the drain port 201.

[0149] During the above process, the spring 120 can release its elastic potential energy after the cleaning component 300 is reset, and drive the ejector 110 to move outward. The trigger part 212, under the action of the second torsion spring 214, drives the blocking part 211 to automatically close the drain port 201 to end the draining.

[0150] By incorporating a spring 120 that engages with the second torsion spring 214, the impact caused by the movement of the ejector 110 can be mitigated, thus protecting the trigger 212. Furthermore, there is no need for an additional structure to drive the switch 210 to close, resulting in lower costs. The resettable switch 210 also provides some leak-proof functionality, improving the sealing performance of the sewage tank 200, reducing the possibility of leakage, and enhancing the user experience.

[0151] The following describes the specific structure of the ejection mechanism 20.

[0152] Reference Figure 2 , Figure 3 , Figure 6 as well as Figure 7 As an optional implementation, the push rod assembly 500 includes a first push rod 510 and a second push rod 520. Both the first push rod 510 and the second push rod 520 are slidably disposed on the housing 400. The first push rod 510 corresponds to the switch 210 of the wastewater tank 200, and the second push rod 520 corresponds to the cleaning assembly 300. The ends of the first push rod 510 and the second push rod 520 are the aforementioned two movable ends 501.

[0153] Reference Figure 7 As can be seen from the foregoing, when the ejection mechanism 20 is in the ejection state, the second ejector rod 520 moves closer to the housing 400, that is, the second ejector rod 520 moves away from the body 100.

[0154] It is understood that the end of the first push rod 510 may be provided with a flat or arc-shaped contact surface that adapts to the trigger part 212, so as to abut against and drive the trigger part 212 to rotate. The material of the first push rod 510 can be selected according to user needs. For example, stainless steel or engineering plastic (such as POM) can be selected, which has high hardness and high wear resistance, and can have a long service life.

[0155] The structure and material of the second push rod 520 can be the same as or different from those of the first push rod 510.

[0156] It should be noted that the movable size range of the first push rod 510 and the second push rod 520, as well as the distance between them, are related to the dimensions of the switch 210, the cleaning component 300, and the body 100. This embodiment does not impose specific limitations on these dimensions, as long as the aforementioned triggering is achieved.

[0157] Reference Figure 6 , Figure 7 In some embodiments, the push rod assembly 500 further includes a connecting rod 530. The connecting rod 530 is located within the housing 400 and connects between the first push rod 510 and the second push rod 520, and is rotatably connected to the housing 400.

[0158] As described above, the first push rod 510 and the second push rod 520 move in opposite directions. Therefore, the first push rod 510, the second push rod 520, and the connecting rod 530 can form a lever structure. When the first push rod 510 moves in one direction, the second push rod 520 can move the same distance in the opposite direction. The same applies when the second push rod 520 moves in one direction.

[0159] The specific process is as follows:

[0160] Reference Figure 2 , Figure 4 as well as Figure 7When the cleaning equipment 10 returns to the base station after completing the cleaning task, the cleaning component 300 can move outward relative to the body 100. The cleaning component 300 abuts against the end of the second push rod 520 and pushes the second push rod 520 back into the housing 400. The second push rod 520 drives the connecting rod 530 to rotate, causing the first push rod 510 to extend outward from the housing 400. The extended first push rod 510 abuts against the trigger part 212 and drives the trigger part 212 and the blocking part 211 to rotate, thereby opening the drain port 201 and realizing the discharge of sewage from the sewage tank 200.

[0161] With the above-described configuration, this embodiment of the application eliminates the need for a power unit in the base station, reducing the complexity and manufacturing cost of the base station. Furthermore, the movements of the cleaning component 300 and the ejection mechanism 20 are transmitted mechanically without signal transmission, thus eliminating signal delay and improving the synchronization of self-cleaning, thereby enhancing the stability of the cleaning system. Simultaneously, the absence of short circuits ensures the normal operation of the cleaning equipment 10, the base station, and the cleaning system, thereby improving the user experience.

[0162] Reference Figure 1 , Figure 3 as well as Figure 6 As an optional implementation, the ejection mechanism 20 also includes an initial state, which can be switched between the initial state and the ejection state.

[0163] Reference Figure 1 , Figure 3 as well as Figure 6 When the ejection mechanism 20 is in its initial state, the movable end 501 of the corresponding cleaning component 300 moves away from the housing 400, and the movable end 501 of the corresponding switch 210 moves closer to the housing 400. At this time, the ejection mechanism 20 is not in contact with either the cleaning component 300 or the switch 210. That is, the cleaning equipment 10 is not in the sewage discharge state.

[0164] Reference Figure 6 , Figure 7 In some embodiments, the ejection mechanism 20 further includes an elastic element 540 disposed between the ejector assembly 500 and the housing 400. The elastic element 540 is configured to retract during the transition of the ejector assembly 500 from the initial state to the ejection state, and to release during the transition of the ejector assembly 500 from the ejection state to the initial state.

[0165] Reference Figure 6 Specifically, when the ejection mechanism 20 is in its initial state, the elastic element 540 is in a released state, corresponding to the movement of the movable end 501 of the cleaning component 300 away from the housing 400 and the movement of the movable end 501 of the switch 210 towards the housing 400. The elastic element 540 being in a released state means that the elastic element 540 is not compressed.

[0166] It is understood that the type of elastic element 540 can be diverse. For example, the elastic element 540 can be any structure with elastic properties, such as a spring 120 or a torsion spring. The embodiments of this application do not limit this, and the appropriate type can be selected according to the actual structure.

[0167] The following is a detailed explanation of the process:

[0168] Reference Figure 1 , Figure 6 When the cleaning equipment 10 is in a working state or standby state (or a non-drainage state), the cleaning component 300 does not extend outward. At this time, the ejection mechanism 20 is in its initial state, and the first ejector 510 of the ejector assembly 500 does not contact the trigger part 212, and the second ejector 520 does not contact the cleaning component 300. The elastic element 540, the second torsion spring 214 of the wastewater tank 200, and the spring 120 are all in the released state. The blocking part 211 seals the drain outlet 201 under the action of the second torsion spring 214.

[0169] Reference Figure 4 , Figure 7 When the cleaning equipment 10 returns to the base station after completing the cleaning task, the cleaning equipment 10 enters the sewage discharge state. At this time, the cleaning component 300 moves outward along its axial direction towards the outside of the body 100, and the ejection mechanism 20 switches from the initial state to the ejection state.

[0170] Reference Figure 2 , Figure 4 , Figure 7 During this process, the cleaning component 300 abuts against the end of the second push rod 520, pushing the second push rod 520 back towards the housing 400. The second push rod 520 drives the connecting rod 530 to rotate, causing the first push rod 510 to extend outward from the housing 400; simultaneously, the elastic element 540 retracts. The extended first push rod 510 abuts against the ejector 110, driving the ejector 110 to move away from the housing 400; simultaneously, the spring 120 extends and retracts. The ejector 110 abuts against the trigger part 212, and the trigger part 212 rotates under the action of the ejector 110, thereby opening the drain port 201, while the second torsion spring 214 retracts; thus realizing the discharge of sewage from the sewage tank 200.

[0171] Reference Figure 1 , Figure 3 , Figure 6 After the cleaning equipment 10 completes the discharge of sewage from the sewage tank 200, the cleaning equipment 10 ends the discharge state. At this time, the cleaning component 300 moves into the machine body 100 along its axial direction to achieve reset, and the ejection mechanism 20 switches from the ejection state to the initial state.

[0172] Reference Figure 1 , Figure 3 , Figure 6During this process, the cleaning component 300 disengages from the end of the second push rod 520. First, the elastic element 540 releases its elastic potential energy, causing the connecting rod 530 to rotate in the opposite direction, which in turn causes the second push rod 520 to move away from the housing 400, and further causes the first push rod 510 to move towards the housing 400, thus disengaging the first push rod 510 from the ejector 110. Then, the spring 120 releases its elastic potential energy, causing the ejector 110 to move towards the housing 400 and disengage from the trigger part 212. Then, the second torsion spring 214 releases its elastic potential energy, causing the blocking part 211 and the trigger part 212 to rotate synchronously, so that the blocking part 211 covers the drain outlet 201, ending the discharge of sewage from the sewage tank 200.

[0173] The ejector mechanism 20, cleaning equipment 10, base station, and cleaning system provided in this application embodiment enable the ejector mechanism 20 to automatically reset without external drive. By setting the elastic element 540, the ejector mechanism 20 is synchronously reset after the cleaning component 300 is reset; and in conjunction with the release of the aforementioned second torsion spring 214 and spring 120, the sewage tank 200 switch 210 is reset to close the sewage outlet 201.

[0174] The above process is completed by a mechanical structure, eliminating the need for a power unit in the base station and reducing its complexity and manufacturing cost. Furthermore, the movements of the cleaning component 300 and the ejection mechanism 20 are both transmitted mechanically, without signal transmission, thus eliminating signal delay and improving the synchronization of self-cleaning, thereby enhancing the stability of the cleaning system.

[0175] In addition, the reset of the elastic element 540 can improve the reliability and consistency of sewage control, ensuring that the ejection mechanism 20 and the cleaning equipment 10 can be repeated multiple times, so as to ensure the normal operation of the cleaning equipment 10, the base station and the cleaning system, thereby improving the user experience.

[0176] As an optional implementation, at least one of the first push rod 510 and the second push rod 520 is provided with a flexible part (not shown in the figure), which is located at the end of the corresponding push rod away from the housing 400.

[0177] Understandably, the flexible part is used to abut against the trigger part 212 of the cleaning component 300 or the switch 210. Compared with a rigid structure, the first push rod 510 and / or the second push rod 520, which are provided with flexible parts, will not damage the trigger part 212 and / or the cleaning component 300, thus ensuring the normal operation of the cleaning component 300.

[0178] Reference Figure 1 , Figure 4As described above, when the cleaning device 10 moves forward along a preset direction, the cleaning component 300 is located in front of the wastewater tank 200, and the wastewater tank 200 is located behind the body 100. Correspondingly, the position of the first push rod 510 corresponds to the switch 210 of the wastewater tank 200, and the position of the second push rod 520 corresponds to the cleaning component 300. Since the body 100 is cylindrical, the first push rod 510 is closer to the edge of the body 100 than the second push rod 520. At this time, in order to ensure that the first push rod 510 can stably abut against the trigger 212, the length of the first push rod 510 can be greater than the length of the second push rod 520.

[0179] On the body 100 of the cleaning device 10, the trigger part 212 is higher than the cleaning assembly 300. At this time, in order to ensure that the first push rod 510 can stably abut against the trigger part 212, the first push rod 510 can be higher than the second push rod 520.

[0180] It should be noted that when the positions of the wastewater tank 200 and the cleaning component 300 on the body 100 change, the positions of the aforementioned first push rod 510 and second push rod 520 can change accordingly to ensure that the first push rod 510 corresponds to the trigger part 212 and the second push rod 520 corresponds to the cleaning component 300.

[0181] As an optional implementation, the first push rod 510 and the second push rod 520 can move in a straight line or a curve relative to the housing 400.

[0182] In some embodiments, at least one of the first push rod 510 and the second push rod 520 is fixedly connected to the end of the connecting rod 530, so that at least one of the first push rod 510 and the second push rod 520 moves along an arc trajectory. At least one of the first push rod 510 and the second push rod 520 includes, but is not limited to, only the first push rod 510, only the second push rod 520, or both the first push rod 510 and the second push rod 520. In the embodiments of this application, the first push rod 510 and the second push rod 520 are respectively fixedly connected to opposite ends of the connecting rod 530.

[0183] It should be noted that a fixed connection refers to a connection between two components where there is no degree of freedom of relative displacement.

[0184] Specifically, when the cleaning component 300 pushes the second push rod 520 back toward the housing 400, the second push rod 520 rotates synchronously along the arc trajectory of the connecting rod 530; at the same time, the connecting rod 530 rotates and drives the first push rod 510 to extend synchronously along another arc trajectory so as to push the trigger part 212.

[0185] Through the above settings, the fixed connection between the first push rod 510, the second push rod 520 and the connecting rod 530 can improve the structural stability of the push rod assembly 500, thereby ensuring the effective triggering of the push mechanism 20, which is conducive to ensuring the effective sewage discharge action of the cleaning equipment 10.

[0186] In some embodiments, the housing 400 has a guide hole extending in a straight direction.

[0187] Understandably, to facilitate the movement of the cleaning component 300, the guide hole can extend in a straight line along the axial direction of the cleaning component 300. For example, the axial direction of the guide hole corresponding to the second push rod 520 can be collinear with the guiding direction of the cleaning component 300. Correspondingly, the trigger part 212 of the switch 210 can be located in the axial direction of the guide hole corresponding to the first push rod 510. In this way, the outwardly moving cleaning component 300 can directly drive the second push rod 520 to retract, and the movement of the cleaning component 300 does not require positioning. The linked first push rod 510 can directly abut against and drive the trigger part 212 to rotate, and the movement of the first push rod 510 also does not require positioning.

[0188] The guide hole refers to a straight through-hole or blind hole structure that penetrates 400 mm of the shell wall thickness, and its cross-section matches the cross-section of the first push rod 510 and the second push rod 520. The guide hole is used to limit the linear movement of the corresponding push rod.

[0189] Specifically, when the cleaning equipment 10 returns to the base station after completing the cleaning task, the cleaning component 300 moves outward along the axial direction towards the outer side of the body 100, the cleaning component 300 abuts against the end of the second push rod 520, and pushes the second push rod 520 back into the housing 400.

[0190] It should be noted that since the connecting rod 530 rotates around the housing 400, while the second push rod 520 moves linearly within the guide hole, if the second push rod 520 and the connecting rod 530 are fixedly connected, the linear movement of the second push rod 520 will conflict with the rotation of the connecting rod 530.

[0191] Therefore, at least one of the first push rod 510 and the second push rod 520 is slidably connected to the end of the connecting rod 530, so that at least one of the first push rod 510 and the second push rod 520 can move in a straight line. The direction in which the first push rod 510 and the second push rod 520 are slidably connected to the connecting rod 530 should intersect with the straight line direction of the guide hole to ensure that the linear and sliding movements of the first push rod 510 and the second push rod 520 can coordinate with the rotation of the connecting rod 530. At least one of the first push rod 510 and the second push rod 520 includes, but is not limited to, only the first push rod 510, only the second push rod 520, or both the first push rod 510 and the second push rod 520. In this embodiment, the first push rod 510 and the second push rod 520 are respectively slidably connected to the opposite ends of the connecting rod 530.

[0192] The specific process is as follows:

[0193] Both the second push rod 520 and the first push rod 510 are constrained by guide holes extending linearly along the housing 400. When the connecting rod 530 rotates under the drive of the second push rod 520, the first push rod 510 is forced to extend outward along the axis of the guide hole; the extended first push rod 510 then contacts and moves toward the trigger part 212, causing the trigger part 212 and the blocking part 211 to rotate around the rotating shaft 213, and then the blocking part 211 leaves the sewage outlet 201, realizing the gravity discharge of sewage.

[0194] With the above settings, the linearly extending guide hole and the sliding connection can constrain the movement trajectory of at least one push rod, which can improve the movement stability of the first push rod 510 and the second push rod 520, reduce the possibility of the trigger part 212 being accidentally touched or not being triggered, ensure that sewage discharge is accurately triggered, and thus ensure the stable operation of the cleaning equipment 10, which can improve the user experience.

[0195] Reference Figure 8 , Figure 9 As an optional implementation, the housing 400 includes a main body 410, a first sleeve 420, and a second sleeve 430.

[0196] Specifically, the main body 410 is installed on the base station of the cleaning system. The main body 410 has a receiving cavity 411, and the connecting rod 530 is located within the receiving cavity 411. Correspondingly, at least a portion of the first push rod 510 and the second push rod 520 are also located within the receiving cavity 411.

[0197] Both the first sleeve 420 and the second sleeve 430 extend in a straight line. Furthermore, both the first sleeve 420 and the second sleeve 430 are located on the side of the main body 410 facing the cleaning device 10 and are connected to the receiving cavity 411. Both the first sleeve 420 and the second sleeve 430 have guide holes. Additionally, the first sleeve 420 corresponds to the switch 210 of the wastewater tank 200, and the second sleeve 430 corresponds to the sleeve. Thus, the first sleeve 420 allows the first push rod 510 to slide, and the second sleeve 430 allows the second push rod 520 to slide.

[0198] In some embodiments, the first sleeve 420 and the second sleeve 430 may be integral with the main body 410 to enhance the connection strength between the first sleeve 420, the second sleeve 430 and the main body 410, thereby ensuring the stable sliding of the first push rod 510 and the second push rod 520.

[0199] In some embodiments, the body 410 has a side facing the wastewater tank 200. The extension direction of the side intersects a straight line direction and the length direction of the connecting rod 530. Exemplarily, the side of the body 410 can be a straight plane or a curved side such as an arc surface.

[0200] As described above, the side of the housing 100 is an annular surface; therefore, the side of the main body 410 can be an arc-shaped surface to match the side of the housing 100. Thus, when the cleaning device 10 is located within the base station, the distances between each position on the arc-shaped surface of the main body 410 and each position on the corresponding side of the housing 100 are equal. In this case, the first push rod 510 and the second push rod 520 can move the same distance to ensure they can abut against the housing 100, and subsequently against the corresponding trigger part 212 and cleaning assembly 300. At this time, the distance between the rotation center of the first push rod 510 and the connecting rod 530, and the distance between the rotation center of the second push rod 520 and the connecting rod 530, can be the same, eliminating the need for a separate connecting rod 530.

[0201] Reference Figure 8 , Figure 9 In some embodiments, a rotating shaft 440 is provided within the housing 400. The push rod assembly 500 includes a connecting rod 530, which is rotatably connected to the housing 400 via the rotating shaft 440. Specifically, the connecting rod 530 has a through hole corresponding to the rotating shaft 440, and the connecting rod 530 is sleeved on the rotating shaft 440 through the through hole to rotate relative to the housing 400, that is, the rotating shaft 440 can pass through the through hole.

[0202] Furthermore, the rotating shaft 440 is fixedly connected to the housing 400 to ensure that there is no relative movement between the rotating shaft 440 and the housing 400, thereby allowing the connecting rod 530 to rotate relative to the housing 400.

[0203] To ensure the connection strength between the connecting rod 530 and the housing 400, the connecting rod 530 and the housing 400 can be integrated as a single piece.

[0204] Reference Figure 8 , Figure 9 As an optional implementation, the elastic element 540 is a first torsion spring 541, which is sleeved on the rotating shaft 440. One end of the first torsion spring 541 abuts against the first push rod 510 or a portion of the connecting rod 530 near the first push rod 510, and the other end of the first torsion spring 541 abuts against the housing 400. That is, both ends of the first torsion spring 541 abut against the housing 400, the first push rod 510, or a portion of the connecting rod 530 near the first push rod 510, respectively.

[0205] The specific process is as follows:

[0206] Reference Figure 8 Change to Figure 9 When the cleaning component 300 moves the second push rod 520 closer to the housing 400 along its axial direction, the connecting rod 530 rotates around the pivot 440, causing the first push rod 510 to move closer to the body 100. At this time, the first torsion spring 541 deflects with the displacement of the connecting rod 530 or the first push rod 510, and its other end is constrained by the housing 400, forming a torsion angle. Therefore, the first torsion spring 541 is torsion and enters an energy storage state.

[0207] Reference Figure 9 Change to Figure 8 When the cleaning component 300 resets and moves away from the housing 400 along its axial direction, the external force pushing the second push rod 520 disappears, and the first torsion spring 541 releases its elastic potential energy, generating a reverse torsional torque. The first torsion spring 541 drives the connecting rod 530 to rotate in the opposite direction, thereby causing both the first push rod 510 and the second push rod 520 to reset. At this time, the ejection mechanism 20 switches from the ejection state to the initial state.

[0208] In the above process, the rotating shaft 440 simultaneously serves as both a rotation fulcrum and a torsion spring mounting shaft, which can improve the space utilization rate inside the housing 400. In this way, the ejection mechanism 20 can occupy a smaller volume inside the base station, thereby providing sufficient cleaning space for the cleaning equipment 10 to ensure the self-cleaning function of the cleaning equipment 10.

[0209] As an optional implementation, the ends of the first push rod 510, the second push rod 520 and the connecting rod 530 can be slidably connected in various ways.

[0210] In some embodiments, a sliding groove is formed at one end of the first push rod 510 near the rotating shaft 440 and at one end of the second push rod 520 near the rotating shaft 440, and the sliding groove extends along the length direction of the connecting rod 530. Both ends of the connecting rod 530 are provided with sliders corresponding to the sliding grooves, and the sliders can slide along the length direction within the sliding grooves. As described above, the first push rod 510 and the second push rod 520 can slide along the length direction of the connecting rod 530 to ensure that the linear and sliding movements of the first push rod 510 and the second push rod 520 can coordinate with the rotation of the connecting rod 530, thereby ensuring the linkage between the first push rod 510 and the second push rod 520.

[0211] In some other embodiments, sliding grooves are formed at both ends of the connecting rod 530, extending along the length of the connecting rod 530. Slider blocks corresponding to the sliding grooves are respectively provided at the ends of the first push rod 510 and the second push rod 520 near the rotating shaft 440, and the sliders can slide along the length of the sliding grooves. As described above, the first push rod 510 and the second push rod 520 can slide along the length of the connecting rod 530 to ensure that the linear and sliding movements of the first push rod 510 and the second push rod 520 can coordinate with the rotation of the connecting rod 530, thereby ensuring the linkage between the first push rod 510 and the second push rod 520.

[0212] Reference Figure 8 , Figure 9 as well as Figure 10 Specifically, the connecting segments of the connecting rod 530 are respectively provided with a first sliding groove 531 and a second sliding groove 532. The end of the first push rod 510 near the rotating shaft 440 is provided with two spaced-apart first plates 511 and a first shaft 512 connecting the two first plates 511. The end of the second push rod 520 near the rotating shaft 440 is provided with two spaced-apart second plates 521 and a second shaft 522 connecting the two second plates 521.

[0213] One end of the connecting rod 530 is located between two first plates 511, and the other end is located between two second plates 521. A first shaft 512 is located within a first sliding groove 531, and a second shaft 522 is located within a second sliding groove 532. Thus, the first shaft 512 can move within the first sliding groove 531, and simultaneously, the second shaft 522 can move within the second sliding groove 532.

[0214] It is understandable that different positions of the first shaft 512 within the first sliding groove 531 can correspond to different states of the ejection mechanism 20. The same applies to the second shaft 522.

[0215] Reference Figure 8 , Figure 9 as well as Figure 10For example, along the length of the connecting rod 530, the two ends of the first sliding groove 531 are respectively the first position 531a and the second position 531b, and the two ends of the second sliding groove 532 are respectively the third position 532a and the fourth position 532b.

[0216] Reference Figure 8 , Figure 10 When the ejector mechanism 20 is in its initial state, the first shaft 512 is in the second position 531b, and the second shaft 522 is in the third position 532a. At this time, the elastic element 540 is in the released state, the first push rod 510 is not in contact with the ejector 110, and the second push rod 520 is not in contact with the cleaning assembly 300.

[0217] Reference Figure 8 Change to Figure 9 as well as Figure 10 During the transition from the initial state to the ejection state of the ejection mechanism 20, the cleaning component 300 moves closer to the housing 400 and continues to move after contacting the second ejector rod 520, thereby moving the second ejector rod 520 away from the body 100. Simultaneously, the second shaft 522 gradually disengages from the third position 532a and moves towards the fourth position 532b. Then, the second ejector rod 520 drives the connecting rod 530 to rotate, and the elastic potential energy of the elastic element 540 gradually increases. The connecting rod 530 rotates, causing the first ejector rod 510 to move closer to the ejector 110; simultaneously, the first shaft 512 gradually disengages from the second position 531b and moves towards the first position 531a.

[0218] Reference Figure 9 , Figure 10 When the ejector mechanism 20 is in the ejector state, the first shaft 512 slides to the first position 531a, and the second shaft 522 is located in the fourth position 532b. The elastic member 540 is in a compressed state; the connecting rod 530 drives the first push rod 510 away from the housing 400 to contact the ejector 110, and causes the ejector 110 to trigger the trigger part 212, so as to realize the sewage discharge of the cleaning equipment 10.

[0219] Reference Figure 9 Change to Figure 8 as well as Figure 10During the transition from the initial state to the ejection state of the ejection mechanism 20, the cleaning component 300 moves away from the housing 400. The elastic potential energy of the elastic element 540 is released, causing the connecting rod 530 to rotate in the opposite direction. The connecting rod 530 causes the second shaft 522 to gradually disengage from the fourth position 532b and move towards the third position 532a; simultaneously, the second ejector rod 520 moves closer to the body 100. At the same time, the connecting rod 530 causes the first shaft 512 to gradually disengage from the first position 531a and move towards the second position 531b. Under the action of the connecting rod 530, the first ejector rod 510 moves closer to the housing 400, thereby disengaging from the ejector 110, thus ending the sewage discharge of the cleaning device 10.
