Detailed Implementation

[0070] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0071] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0072] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0073] In existing technologies, different cleaning needs typically require different cleaning equipment; that is, one cleaning device is equipped with one cleaning module to meet one cleaning need. However, since homes, offices, or sports venues usually have multiple cleaning needs, such as washing, vacuuming, and disinfection, each type of venue needs to be equipped with multiple cleaning devices to meet these diverse needs. This not only increases costs but also increases the space occupied by the cleaning equipment. Furthermore, while some related technologies incorporate multiple cleaning modules into a single cleaning device to meet various needs, this can easily result in excessively large individual cleaning modules, increasing the space requirements of the cleaning device. This is not conducive to cleaning smaller areas, such as under beds, under tables and chairs, under sofas, and in corners, or the effective volume may be too low, significantly shortening the continuous cleaning capacity of the cleaning device and thus affecting the user experience.

[0074] This application proposes a cleaning device.

[0075] Please refer to Figures 1 to 3. In one embodiment of this application, the cleaning device includes:

[0076] The equipment host 100 is provided with a first connection structure 110 and at least one universal component 300, the universal component 300 being used to control the operation of the cleaning equipment; and

[0077] The work module 200 is provided with a second connection structure 210. The first connection structure 110 and the second connection structure 210 are detachably connected. At least one universal component 300 controls the conduction to the work module 200. The work module 200 is used to clean dirt.

[0078] The technical solution of this application involves providing a first connection structure 110 on the main unit 100 and a second connection structure 210 on the work module 200. The work module 200 is installed on the main unit 100 using the first and second connection structures 110 and 210, allowing the universal component 300 to function on both the main unit 100 and the work module 200, ensuring that the work module 200 can complete the predetermined cleaning requirements. Here, the first and second connection structures 110 and 210 are detachably connected. After the cleaning equipment completes the current cleaning requirement, the connection between the first and second connection structures 110 is released, and another work module 200 is replaced. The second connection structure 210 of the other work module 200 is then connected to the first connection structure 110 of the main unit 100 to complete another cleaning task. In this way, by replacing different operating modules 200 on a single device host 100, different operating modules 200 can be used to meet different cleaning needs, thereby avoiding the need to set up multiple cleaning devices, reducing costs and space occupation, while also ensuring that the size of a single cleaning device is reasonable and has good continuous cleaning capabilities, thus improving the user experience.

[0079] It should be noted that the general-purpose component 300 can be electrically connected to the working module 200 to control the working module 200. For example, if the general-purpose component 300 is an energy storage component, it can drive the roller brush of the working module 200 to clean the dirt on the area to be cleaned. Alternatively, it can be structurally integrated to apply the function of the general-purpose component 300 to the working module 200, enabling the working module 200 to clean the external environment. For example, if the general-purpose component 300 is configured as a fan assembly 301, the fan can act on the working module 200 through the air duct, allowing the working module 200 to suck up the dirt on the area to be cleaned. Or, the general-purpose component 300 can only act on the main unit 100 of the equipment to meet the automatic operation function of the cleaning equipment, such as movement and obstacle avoidance. Furthermore, the directional indicators such as the first direction and the second direction mentioned in the various embodiments of this application refer to Figure 1. When the posture of the cleaning equipment in Figure 1 changes, the directional indicators also change accordingly. The descriptions of up and down directions are based on the normal operating state of the cleaning equipment. "Parallel" is understood as being parallel or nearly parallel to each other. Without loss of generality, the cleaning equipment can be a semi-automatic cleaning device, such as a handheld floor scrubber or a handheld vacuum cleaner, or a fully automatic cleaning robot, such as an automatic vacuum cleaner or an automatic sweeping robot. In this embodiment, the cleaning equipment is configured as a cleaning robot to provide cleaning, vacuuming, and disinfection operations on carpets, floors, and other areas awaiting cleaning.

[0080] In one embodiment, referring to Figures 1, 5, and 7, the general-purpose component 300 is configured as at least one of an energy storage component (not shown), a fan component 301, a drive component (not shown), and a detection component 302. It is understood that the general-purpose component 300 is a component with good compatibility, capable of independently satisfying the operation of the main equipment 100, or fulfilling the common functions of each work module 200. Therefore, these general-purpose components 300 are placed in the main equipment 100 to reduce the cost of the work modules 200. Specifically, the energy storage component provides power for the cleaning equipment's cleaning, movement, and obstacle avoidance, such as a battery; the fan component 301 provides suction to the work module 200 to remove dirt from the cleaning area, such as a fan and part of the air duct structure; the drive component controls the cleaning equipment's movement and obstacle avoidance, such as a motor, drive wheels 150, and steering wheels; and the detection component 302 detects the environment around the cleaning equipment, providing support for planning the travel path, avoiding obstacles, and targeted cleaning. Of course, depending on the different cleaning equipment, the operating requirements of the main unit 100, and the common requirements of different operating modules 200, the general-purpose component 300 can also be configured as other components, such as inlet and outlet pipes, anti-collision plates 160, etc. In other embodiments, the fan assembly 301 can also be set in the operating module 200, reducing the design difficulty of the ventilation duct connecting the fan assembly 301 and the operating module 200.

[0081] Correspondingly, the operation module 200 is configured according to different cleaning needs. In one embodiment, referring to Figures 1, 5, and 7, the operation module 200 is configured as at least one of a cleaning module 201, a vacuuming module 202, and a disinfection module (not shown). It should be noted that the cleaning module 201 cleans the area to be cleaned by washing with water, such as a combination of a mop or a roller brush with a suction nozzle, and is equipped with a clean water tank and a wastewater tank to ensure continuous and remote cleaning capabilities. The vacuuming module 202 generates suction through a fan assembly 301, using a suction nozzle and a dust inlet duct to remove dirt from the area to be cleaned, achieving dust removal and cleaning. The disinfection module sterilizes and disinfects the area to be cleaned using hot air, disinfectant, or light disinfection to ensure that the bacterial content of the area to be cleaned is at a low level. Furthermore, the operation module 200 can be equipped with additional functions beyond its basic cleaning function, such as a disinfection module with an added roller brush cleaning function to enhance the disinfection depth. Of course, in other embodiments, other cleaning function operation modules 200, such as humidification modules and drying modules, can be set according to the configuration of the general component 300.

[0082] In one embodiment, referring to Figures 2, 5, and 7, the work module 200 is connected to the device host 100 via a vertical plug-in connection. It should be noted that the cleaning equipment is configured as a mobile cleaning robot, capable of moving horizontally to a predetermined cleaning location for automated cleaning. Here, the vertical plug-in connection effectively limits the shaking of the work module 200 on the horizontal plane, ensuring the connection stability between the work module 200 and the device host 100, reducing shaking and noise during the cleaning process, and ensuring the cleaning equipment maintains efficient and stable operation over extended periods. Simultaneously, the vertical plug-in design allows users to easily install or remove the work module 200 with simple up-and-down movements, eliminating the need for complex rotation, twisting, or other complicated operations, thus reducing the user's operational difficulty. Of course, in other embodiments, the work module 200 can also be connected to the device host 100 via a horizontal plug-in connection, or the work module 200 can be detachably connected to the device host 100 via a screw connection.

[0083] In one embodiment, referring to Figures 2 to 4, the first connecting structure 110 includes a second limiting rib 111 extending vertically, and the second connecting structure 210 includes a second limiting groove 211 extending vertically. The second limiting rib 111 is engaged with the second limiting groove 211. It can be understood that the second limiting rib 111 and the second limiting groove 211 effectively restrict the horizontal movement of the working module 200 relative to the main equipment 100, preventing lateral displacement of the working module 200 when subjected to horizontal forces during cleaning operations. Simultaneously, the second limiting groove 211 and the second limiting rib 111 extend vertically. Through the interaction of the second limiting rib 111 and the second limiting groove 211, the load-bearing capacity of the connecting structure in the horizontal direction at various points along the height of the cleaning equipment is significantly improved. This ensures that the working module 200 maintains a stable connection even when subjected to large horizontal forces, preventing it from easily detaching or loosening. This guarantees convenient assembly and disassembly while also improving the stability of the cleaning equipment during cleaning operations. Of course, in other embodiments, the first connecting structure 110 may also be a recessed groove on the horizontal plane, and the second connecting structure 210 may be a raised part on the horizontal plane. The cooperation between the raised part and the groove enables the working module 200 and the device host 100 to have a limiting connection relationship on the horizontal plane.

[0084] Further, in this embodiment, referring to Figures 2 to 4, the spacing of the second limiting ribs 111 in the first direction gradually increases from top to bottom, and the spacing of the second limiting grooves 211 in the first direction gradually increases from bottom to top. The second limiting ribs 111 are adapted to be engaged in the second limiting grooves 211, and the first direction is parallel to the distribution direction of the device host 100 and the working module 200. It can be understood that when the working module 200 is vertically inserted into the device host 100, due to the gradual change in the spacing of the second limiting ribs 111 and the second limiting grooves 211 in the first direction, their cooperation will present a progressive locking effect. As the insertion depth increases, the friction between the second limiting ribs 111 and the second limiting grooves 211 gradually increases, thereby achieving a more secure connection to more effectively resist the shaking between the device host 100 and the working module 200. Meanwhile, this progressive locking method makes the installation process simpler and more intuitive. When users feel the tight fit between the second limiting rib 111 and the second limiting groove 211, they can intuitively judge the connection stability of the second limiting rib 111 and the second limiting groove 211, thereby improving the user experience.

[0085] In one embodiment, referring to Figures 2, 6, and 8, the first connecting structure 110 includes a third latching protrusion 116 that can move horizontally, and the second connecting structure 210 includes a second latching groove 212 with a horizontally arranged opening. The third latching protrusion 116 is adapted to be latched into the second latching groove 212. It can be understood that when the third latching protrusion 116 is fully latched into the second latching groove 212, a locking mechanism is formed in the vertical direction, effectively preventing the equipment host 100 and the working module 200 from shaking or shifting in the vertical direction, ensuring the operational stability of the cleaning equipment. Simultaneously, regarding the horizontal movement of the third latching protrusion 116, during the vertical insertion process of the working module 200 into the equipment host 100, the third latching protrusion 116 can first avoid the second latching groove 212. After the working module 200 is inserted into place, the third latching protrusion 116 can then move horizontally to the position of the second latching groove 212 for latching, avoiding installation difficulties caused by interference between the third latching protrusion 116 and the second latching groove 212 during the insertion process. Furthermore, since the third latching protrusion 116 can move horizontally, the user can more accurately adjust the position of the work module 200, ensuring precise alignment between the work module 200 and the device host 100, reducing the risk of loose connection or damage due to improper installation. Of course, in other embodiments, the movable third latching protrusion 116 can also be provided in the work module 200, and the second latching slot 212 that engages with it can be provided in the device host 100.

[0086] Further, in this embodiment, referring to Figures 5 to 8, the first connecting structure 110 also includes a second guide cylinder 112 and a movable member 119. The second guide cylinder 112 has a second opening 113 in the horizontal direction. The movable member 119 is slidably inserted into the second guide cylinder 112 and is movably connected to the third locking protrusion 116, so as to have an unlocking position that pulls the third locking protrusion 116 back into the second guide cylinder 112 and a locking position that pushes the third locking protrusion 116 out of the second guide cylinder 112. It can be understood that the user only needs to push or pull the movable member 119 to realize the retraction and extension of the third locking protrusion 116, thereby completing the unlocking and locking of the first connecting structure 110 and the second connecting structure 210, reducing the operation steps. In addition, the second guide cylinder 112 and the movable member 119 make the first connecting structure 110 easy to maintain and adjust, without the need for large-scale disassembly of the entire first connecting structure 110. Meanwhile, the second guide cylinder 112 provides a stable support structure for the movable part 119 and the third locking protrusion 116. For example, the second guide cylinder 112 restricts the sliding direction of the movable part 119, ensuring the stability and accuracy of the third locking protrusion 116 during the extension and retraction process, thereby ensuring the stability of the third locking protrusion 116 in the unlocked and locked positions, and helping to prevent the first connecting structure 110 from deforming or being damaged by external forces. Of course, in other embodiments, the third locking protrusion 116 can also be configured as part of an insertion rod. After the main unit 100 and the working module 200 are connected to the predetermined position, the insertion rod is horizontally inserted at the connection between the main unit 100 and the working module 200, so that the third locking protrusion 116 is locked in the second slot 212, thereby ensuring the connection stability of the main unit 100 and the working module 200 in the vertical direction.

[0087] Regarding the connection between the movable member 119 and the third latching protrusion 116, in one embodiment, referring to Figures 5 and 6, the movable member 119 and the third latching protrusion 116 are rotatably connected by a connecting rod 117. In the unlocked position, the rotatable connection between the connecting rod 117 and the movable member 119 is located away from the second passage 113, and in the locked position, the rotatable connection between the connecting rod 117 and the movable member 119 is located close to the second passage 113. It is understood that in the unlocked position, the rotatable connection between the connecting rod 117 and the movable member 119 is positioned away from the second passage 113, thereby pulling the third locking protrusion 116 back into the second guide cylinder 112 to disengage the third locking protrusion 116 from the second slot 212. In the locked position, the rotatable connection between the connecting rod 117 and the movable member 119 is positioned close to the second passage 113, so that the connecting rod 117 pushes the third locking protrusion 116 outward from the second passage 113, ensuring that the third locking protrusion 116 can accurately engage in the second slot 212, which helps to maintain stability when the third locking protrusion 116 extends outward from the second guide cylinder 112. At the same time, the user can simply push or pull the movable member 119 to change the horizontal tilt of the connecting rod 117, thereby pulling the third locking protrusion 116 to its horizontal position, thus realizing the switching between the unlocked and locked positions of the third locking protrusion 116. In addition, the two ends of the connecting rod 117 are rotatably connected to the third locking protrusion 116 and the movable part 119, respectively, which helps to reduce the wear between the movable part 119 and the third locking protrusion 116, ensure the durability of the first connecting structure 110, and the connection stability between the main unit 100 and the working module 200.

[0088] In another embodiment, referring to Figures 7 and 8, the movable member 119 and the third locking protrusion 116 are provided with a second guide inclined wall 121 for sliding contact. The extension direction of the second guide inclined wall 121 is inclined relative to the axial direction of the second guide cylinder 112 and the extension direction of the movable member 119. It can be understood that when the movable member 119 moves along the axial direction of the second guide cylinder 112, the second guide inclined wall 121 on it interacts with the second guide inclined wall 121 on the third locking protrusion 116, thereby pushing the third locking protrusion 116 to move in a direction different from the axial direction of the second guide cylinder 112. This allows the movable member 119 to smoothly guide the third locking protrusion 116 to move horizontally during movement, ensuring the stability of the third locking protrusion 116 when switching between the unlocked and locked positions. Simultaneously, the inclined arrangement of the second guide inclined wall 121 causes the contact area between the third locking protrusion 116 and the movable member 119 to gradually change as the movable member 119 moves, thereby dispersing friction and making the steering movement smoother. In addition, by optimizing the tilt angle and extension direction of the second guide wall 121, the first connecting structure 110 can be made more stable when subjected to external forces, thereby improving its durability and ensuring the stable and reliable transmission cooperation between the third locking protrusion 116 and the moving part 119, thereby improving the connection stability between the main equipment 100 and the working module 200.

[0089] Specifically, in this embodiment, referring to Figures 6 and 8, a limiting protrusion 115 is also provided inside the second guide cylinder 112, and the movable member 119 is recessed with a first positioning groove 122. The limiting protrusion 115 can slide along the axial direction of the second guide cylinder 112 and is slidably connected to the first positioning groove 122. In the unlocked and locked positions, the limiting protrusion 115 abuts against the corresponding groove wall of the first positioning groove 122 distributed axially in the second guide cylinder 112. It can be understood that the cooperation between the limiting protrusion 115 and the first positioning groove 122 provides a clear definition of the movement range of the movable member 119 within the second guide cylinder 112, thereby limiting the maximum movement distance of the movable member 119 in the axial direction of the second guide cylinder 112, preventing the movable member 119 from exceeding the predetermined range during movement, and avoiding damage to the connection structure or the inability of the third locking protrusion 116 to maintain a stable state in the unlocked or locked positions due to excessive movement. Meanwhile, when the third locking protrusion 116 is in the unlocked and locked positions, the limiting protrusions 115 abut against the corresponding groove walls of the first positioning groove 122 axially distributed in the second guide cylinder 112, ensuring that the moving part 119 can stop precisely when it reaches these two key positions, thereby ensuring that the third locking protrusion 116 can accurately switch to the unlocked or locked position. Of course, in other embodiments, a limiting structure can also be provided in the second guide cylinder 112 to prevent the moving part 119 from coming out of the second guide cylinder 112.

[0090] In one embodiment, referring to Figures 6 and 8, the first connecting structure 110 further includes an elastic element 118. The elastic element 118 is sandwiched between the movable element 119 and the second guide cylinder 112, and its elastic extension direction is parallel to the axial direction of the second guide cylinder 112. In the unlocked position, the elastic element 118 is in an elastically compressed state, and in the locked position, the elastic element 118 is in an elastically extended state. It can be understood that the elastic element 118 enables the movable element 119 to automatically reset when switching between the unlocked and locked positions. The user only needs to apply an initial force to push or pull the movable element 119, after which the elastic element 118 will take over and automatically reset the movable element 119, pulling the third locking protrusion 116 back to the locked state, thereby simplifying the user's operation process. Simultaneously, when the third latch 116 is in the unlocked position, the elastic element 118 is in an elastically compressed state, providing a reverse elastic pushing force to the movable element 119, thus providing the user with a clearer pressing feel, helping the user to determine whether the third latch 116 has switched to the unlocked position, facilitating the replacement of the operating module 200. Referring to Figure 6, when the movable element 119 is connected to the third latch 116 via the connecting rod 117, the elastic element 118 is located between the bottom of the movable element 119 and the bottom wall of the second guide cylinder 112, exhibiting vertical elastic extension and contraction. Referring to Figure 8, when the movable element 119 is connected to the third latch 116 via the guide ramp, the elastic element 118 is located between the inner wall of the second guide cylinder 112 and the second passage 113 opposite to the third latch 116. The elastic element 118 exhibits horizontal elastic extension and contraction. Specifically, the elastic element 118 is configured as one of a compression spring, a tension spring, or a spring sheet. Of course, in other embodiments, the movable member 119 can also be stably engaged with the second guide cylinder 112 when the third latching protrusion 116 is in the unlocked position and the locked position. When the user controls the third latching protrusion 116 to switch between the unlocked position and the locked position, the movable member 119 needs to break through the engagement relationship with the second guide cylinder 112 twice to disengage from the unlocked position and enter the locked position, or disengage from the locked position and enter the unlocked position.

[0091] In one embodiment, referring to Figure 1, a clearance opening 114 is provided on the side wall of the second guide cylinder 112 adjacent to the outer periphery of the cleaning device. A button 123 is provided on the movable component 119. The button 123 is slidably connected to the clearance opening 114 along the axial direction of the second guide cylinder 112, and is exposed on the outer periphery of the cleaning device. From a top view of the cleaning device, the clearance opening 114 is located at the periphery of the cleaning device, that is, on the vertically extending side wall of the cleaning device, thus avoiding a more obvious viewing position of the cleaning device. The entire cleaning device has a simpler and smoother appearance, without any abrupt parts or lines, thereby enhancing the overall aesthetics of the product. At the same time, the button 123 being exposed on the outer periphery of the cleaning device allows the user to easily reach and operate the button 123, avoiding the inconvenience of the user needing to search for or move the cleaning device to access the button 123, thus improving operational convenience. The second guide cylinder 112 extends vertically, and the clearance opening 114 is located on the side wall of the vertically extending second guide cylinder 112, adjacent to the outer periphery of the cleaning device. Of course, in other embodiments, the clearance opening 114 may also be located at the axial end of the second guide cylinder 112, and the button 123 is located on the side wall of the cleaning device extending horizontally.

[0092] Further, in this embodiment, referring to Figure 2, the second guide cylinder 112 is positioned adjacent to the drive wheel 150 of the cleaning device. The cleaning device also includes a crash barrier 160 disposed on its outer periphery. The crash barrier 160 is provided with a clearance opening 161 extending parallel to and opposite to the clearance opening 114, and the button 123 is exposed in the clearance opening 161. It can be understood that the button 123 is exposed outside the crash barrier 160 through the clearance opening 161, but is actually still hidden under the protection of the crash barrier 160. This hidden installation method maintains the integrity of the crash barrier 160, allows the button 123 to be easily accessed during operation, and does not damage the aesthetics of the crash barrier 160. Meanwhile, the second guide cylinder 112 is positioned adjacent to the drive wheel 150, and the button 123 is installed using the clearance opening 161 on the anti-collision plate 160. This avoids the need for additional external space to be occupied due to the installation of the button 123, making full use of the internal and external space of the cleaning equipment. Through a compact layout, not only are functional requirements met, but the overall structure of the cleaning equipment is also more compact and reasonable. Of course, in other embodiments, the second guide cylinder 112 is positioned in different locations depending on the layout of the components inside the cleaning equipment, such as near the fan or near the detection component 302.

[0093] In one embodiment, referring to Figures 2 to 4, the first connecting structure 110 is further provided with a support protrusion 130 near its bottom, and the second connecting structure 210 has a relief groove 230 formed on its bottom wall. The support protrusion 130 is adapted to be inserted into the relief groove 230 and abuts against it in the vertical direction. After the working module 200 is installed on the main unit 100, the tight fit between the support protrusion 130 and the relief groove 230 provides direct vertical support for the working module 200, ensuring the stability of the working module 200 in the vertical direction and preventing shaking or displacement caused by vibration, tilting, or external forces. At the same time, the abutment between the support protrusion 130 and the relief groove 230 can effectively distribute the weight and force of the working module 200, helping to maintain the overall structural and performance stability of the cleaning equipment. In addition, the adapted connection between the support protrusion 130 and the relief groove 230 allows the first connecting structure 110 and the second connecting structure 210 to be tightly connected together, thereby optimizing the space utilization of the equipment. Of course, in other embodiments, the second limiting rib 111 can also be set as a stepped shape with smaller upper part and larger lower part or from top to bottom to provide vertical support for the working module 200 of the host device 100.

[0094] Further, in this embodiment, referring to Figures 2 to 4, the support protrusion 130 is provided with a first terminal member 131, and the clearance groove 230 is provided with a second terminal member 220. The first terminal member 131 and the second terminal member 220 are inserted into each other in the vertical direction for electrical conduction. It can be understood that while the working module 200 and the equipment host 100 are connected, the first terminal member 131 and the second terminal member 220 are also simultaneously inserted, ensuring that the universal component 300 of the equipment host 100 can function on the working module 200, enabling the working module 200 to operate stably, ensuring the operational stability of the cleaning equipment, and improving the convenience of connecting the working module 200 and the equipment host 100. The stable connection of the first terminal member 131 and the second terminal member 220 ensures that the working module can obtain a continuous power supply from the equipment host 100. Meanwhile, the connection between the first terminal component 131 and the second terminal component 220 can also utilize the gravity of the working module 200, ensuring a stable connection and reducing the probability of poor contact. This reduces downtime and maintenance costs due to equipment malfunctions. Furthermore, since the first terminal component 131 and the second terminal component 220 are located inside the cleaning equipment, specifically on the contact surfaces between the main unit 100 and the working module 200, they are less susceptible to moisture and dust intrusion, improving the stability and reliability of the universal component 300, especially in humid or harsh environments during wet operations such as cleaning and disinfection. Of course, in other embodiments, the first terminal component 131 and the second terminal component 220 can also be positioned for separate connection, with the first terminal component 131 and the second terminal component 220 connected after the working module 200 is installed on the main unit 100 via the second connection structure 210 and the first connection structure 110.

[0095] In one embodiment, referring to Figures 2 to 4, the support protrusion 130 is positioned adjacent to the drive wheel 150 of the cleaning equipment, and a cliff detection component (not shown) is provided on the support protrusion 130. By integrating the cliff detection component onto the support protrusion 130, a tight integration of the detection function and the support structure is achieved, which not only reduces the overall size of the equipment but also improves its structural compactness and integration. Simultaneously, the support protrusion 130 and the cliff detection component on it are located at the bottom of the equipment, ensuring that the cliff detection component maintains an appropriate distance from the ground. Positioning the support protrusion 130 adjacent to the drive wheel 150 allows for accurate detection of whether the cleaning equipment is near dangerous areas such as stairs or edges, thereby improving the accuracy and reliability of the detection. In this embodiment, referring to the following description of the distribution of the two first connecting structures 110 in the second direction, it can be understood that the main unit 100 has two support protrusions 130, one support protrusion 130 having a first terminal piece 131, and the other support protrusion 130 having a cliff detection component. Of course, in other embodiments, the cliff detection component can also be located in the work module 200.

[0096] In one embodiment, referring to Figures 2 and 3, the main unit 100 includes two first connecting structures 110, and the operating module 200 includes two second connecting structures 210. One first connecting structure 110 is connected to one second connecting structure 210. The two first connecting structures 110 or the two second connecting structures 210 are distributed along a second direction and are located adjacent to the outer periphery of the cleaning equipment. The second direction intersects the distribution direction of the operating module 200 and the main unit 100. It can be understood that, with the distribution direction of the main unit 100 and the operating module 200 as the central axis, the two first connecting structures 110 and the two second connecting structures 210 distributed along the second direction are positioned on both sides of the central axis. This effectively disperses the force between the main unit 100 and the operating module 200 in the second direction, thereby ensuring the stability and firmness of the connection between the main unit 100 and the operating module 200 in the first direction. Simultaneously, when the cleaning equipment is turning or experiencing uneven force with the supporting ground in the second direction, it can resist lateral forces on the cleaning equipment, preventing the cleaning equipment from tipping over or becoming uncontrollable. Without loss of generality, the two first connecting structures 110 or the two second connecting structures 210 are symmetrically distributed on the main unit 100 in the second direction, so that the force between the main unit 100 and the working module 200 tends to be uniform throughout the second direction. This can better balance the vibration of the equipment during operation, avoid tailing, and ensure the stability of the cleaning equipment operation. Of course, in other embodiments, the main unit 100 may also be provided with only one first connecting structure 110, which is located in the middle of the main unit 100 in the second direction. Correspondingly, the second connecting structure 210 is also located in the middle of the working module 200 in the second direction.

[0097] In one embodiment, referring to FIG2, the main unit 100 is recessed to form a mounting position 140. The working module 200 includes a storage box (not shown), which is adapted to be disposed in the mounting position 140. The storage box is used to store waste. It can be understood that the recessed mounting position 140 of the main unit 100 provides a stable support platform for the storage box, thereby enhancing the stability of the vertical support of the working module 200 by the main unit 100. Simultaneously, the recessed mounting position 140 allows the storage box of the working module 200 to fit tightly against the main unit 100 during installation, increasing the number and position of the interaction surfaces between the working module 200 and the main unit 100, thereby improving the stability of the working module 200 on the main unit 100. Furthermore, by adapting the storage box to be disposed within the recessed mounting position 140 of the main unit 100, the internal space of the main unit 100 can be fully utilized, improving the compactness of the cleaning equipment. For the storage box used to store dirt, the storage box is integrated as part of the working module 200 and adapted to be installed in the recessed mounting position 140 of the main unit 100. This creates a clear functional partition between the storage box and other parts of the main unit 100. When facing different cleaning needs, common components are placed in the main unit 100 as much as possible, while characteristic components corresponding to the cleaning needs are placed in the working module 200. This achieves a reasonable division between the main unit 100 and the working module 200, thereby reducing costs.

[0098] In one embodiment, referring to Figures 9 and 10, the general-purpose component is configured as a fan assembly 301. The fan assembly 301 includes a fan body and a main air duct 170 connected to the fan body. The operating module 200 is provided with an exhaust air duct 240, which is connected to the main air duct 170 and is used to exhaust the airflow generated by the fan body. It can be understood that the exhaust airflow of the cleaning equipment is divided into two parts: the main air duct 170 on the main equipment 100 and the exhaust airflow on the operating module 200. The fan body in the fan assembly 301 is located on the main equipment 100, and the fan body and the main air duct 170 are adapted to the exhaust air ducts 240 of different operating modules 200. This maximizes the installation of common equipment on the main equipment 100, reducing costs. At the same time, it ensures that the cleaning equipment can complete the corresponding cleaning task after switching between different operating modules 200. Of course, in other embodiments, the fan assembly 301 can also be set on the operation module 200 to reduce the design difficulty of the exhaust channel and enable the main unit 100 to meet more operation modules 200.

[0099] Further, in this embodiment, referring to Figures 10 and 11, the main unit air duct 170 forms a first interface 171 on the main unit 100, and the exhaust air duct 240 forms a second interface 241 on the operating module 200. The first interface 171 is inclined at an angle α relative to the horizontal plane, and the first interface 171 and the second interface 241 are adapted to communicate, where α satisfies: 30°≤α≤60°. At the junction of the main unit air duct 170 and the exhaust air duct 240, the first interface 171 is in an upward and horizontally inclined posture, which is suitable for the vertical installation of the operating module 200 on the main unit 100, ensuring the sealing of the interface between the first interface 171 and the second interface 241. Specifically, setting the horizontal tilt angle α of the first interface 171 to be greater than or equal to 30° and less than or equal to 60° can improve the sealing of the first interface 171 and the second interface 241 by utilizing the installation direction of the working module 200 and gravity. It also reduces the curvature of the exhaust airflow channel formed by the connection of the main unit air duct 170 and the exhaust air duct 240, ensuring smooth airflow and thus guaranteeing exhaust efficiency. Specifically, α is set to 30°, 36°, 40°, 45°, 50°, 56°, or 60°, etc. Of course, in other embodiments, α can also be set to less than 30° or greater than 60° depending on the position of the exhaust air duct 240 and the main unit air duct 170 and the distribution of components within the cleaning equipment.

[0100] In one embodiment, referring to Figures 10 and 11, a sealing ring groove 173 is recessed on at least one side of the abutment periphery of the first interface 171 and the second interface 241. A sealing ring is provided in the sealing ring groove 173, and the sealing ring is sandwiched between the abutment periphery of the first interface 171 and the second interface 241. The sealing ring is annularly arranged around the abutment of the first interface 171 and the second interface 241, forming a sealed protection for the exhaust channel at the joint of the first interface 171 and the second interface 241, preventing airflow leakage at this point and ensuring the reliability and stability of the fan assembly 301. Simultaneously, the sealing ring groove 173 provides an installation position for the sealing ring, facilitating its positioning and installation, and also promoting its deformation, thereby ensuring the sealing of the circumferential joint between the first interface 171 and the second interface 241. Of course, in other embodiments, the first interface 171 can also be inserted into the second interface 241.

[0101] Regarding the cleaning equipment after the work module 200 is removed, i.e., on the main unit 100, in one embodiment, referring to Figures 10 and 11, a guide frame 172 is provided on the first interface 171. The guide frame 172 is arranged in a grid shape on the first interface 171. It can be understood that the guide frame 172 can provide support for the first interface 171 within the first interface 171 to ensure its stability. This ensures the stability and sealing of the connection between the first interface 171 and the second interface 241 during the disassembly and assembly of the work module 200. Simultaneously, after the main unit 100 and the work module 200 are separated, the guide frame 172 not only prevents foreign objects from entering the main unit's air duct 170, ensuring the stability of the subsequent airflow from the main unit's air duct 170 to the exhaust air duct 240, but also, during the operation of the cleaning equipment, the guide frame 172 rectifies and divides the airflow from the fan body to reduce the possibility of eddies in the exhaust air duct 240, thereby improving airflow efficiency. Of course, in other embodiments, a protective cover may also be provided at the first interface 171, which is covered when the device host 100 is placed alone and removed when the device host 100 and the operation module 200 are connected.

[0102] This application proposes a cleaning device.

[0103] Referring to Figures 12, 13, and 16, in one embodiment of this application, the cleaning device includes:

[0104] Device host 100, device host 100 is provided with a first connection structure 110; and

[0105] The work module 200 is provided with a second connection structure 210. The first connection structure 110 and the second connection structure 210 are detachably connected. The work module 200 is used to clean dirt.

[0106] The technical solution of this application provides a first connection structure 110 on the main unit 100, and correspondingly, a matching second connection structure 210 on the operation module 200, enabling quick, stable, and fully functional docking with the first connection structure 110. Through the detachable connection of the first connection structure 110 and the second connection structure 210, users can flexibly replace different functional operation modules 200 according to actual cleaning scenarios—for example, a vacuuming module for dry waste cleaning, a floor-washing module for wet mopping, a steam module for sterilization and disinfection, and a crevice cleaning module specifically for operations in confined areas. After each operation module 200 is installed on the main unit 100, it not only achieves mechanical fixation but also automatically connects to power, signal transmission, or liquid / airflow channels, enabling the drive, control, and power supply systems of the main unit 100 to efficiently coordinate with the assigned operation module 200 to complete the predetermined cleaning task. Thus, the main unit 100 can be reused as a universal platform for a long time; different cleaning needs can be met simply by replacing different operation modules 200, reducing the user's usage threshold and maintenance costs.

[0107] It should be noted that the main unit 100 of the equipment can be equipped with universal components that can be adapted to different operating modules 200 to control the operating modules 200. For example, if the universal component is an energy storage assembly, it can drive the roller brush movement of the operating module 200 to clean the dirt on the area to be cleaned. Alternatively, through structural cooperation, the function of the universal component can be applied to the operating module 200, enabling the operating module 200 to clean the external environment. For example, if the universal component is configured as a fan assembly, the fan can act on the operating module 200 through the air duct, allowing the operating module 200 to suck up the dirt on the area to be cleaned. Or, the universal component can only act on the main unit 100 of the equipment to meet the automatic operation function of the cleaning equipment, such as movement and obstacle avoidance. In addition, the directional descriptions of up, down, front, back, left, and right in the various embodiments of this application are based on the normal operating state of the cleaning equipment. Among them, parallel is understood as being parallel or nearly parallel to each other. Without loss of generality, the cleaning equipment can be a semi-automatic cleaning device, such as a handheld floor scrubber or a handheld vacuum cleaner, or a fully automatic cleaning robot, such as an automatic vacuum cleaner, an automatic sweeping robot, or an air purifier. In this embodiment, the cleaning equipment is configured as a cleaning robot to provide cleaning operations such as washing, vacuuming, and disinfecting carpets, floors, and other surfaces awaiting cleaning.

[0108] In one embodiment, referring to Figures 13 and 16, the first connecting structure 110 includes a first slot 181, and the second connecting structure 210 includes a movably configured first protrusion 251, which is fitted and engaged with the first slot 181. It can be understood that the first protrusion 251 is configured to elastically displace or rotate under external force, and automatically reset and engage with the first slot 181 after alignment, thereby achieving a quick, stable, and detachable connection between the work module 200 and the main unit 100. This not only simplifies the user's operation process for replacing the work module 200, allowing installation or disassembly without tools, but also effectively prevents the work module 200 from accidentally falling off during operation due to vibration or force, ensuring the safety and stability of the cleaning operation. In addition, when the user is assembling or disassembling the work module 200 on the main unit 100, the user usually acts on the work module 200. At the same time, the movable first card protrusion 251 is also on the work module 200. In this way, the user can connect the first card protrusion 251 and the first card slot 181 at the same time by moving the work module 200, thereby simplifying the operation difficulty of assembling or disassembling the work module 200 on the main unit 100.

[0109] Further, in this embodiment, referring to Figures 16 to 18, the second connection structure 210 also includes a slidably disposed slider 252. The sliding direction of the slider 252 forms an angle with the movement direction of the first latching protrusion 251. The slider 252 is movably connected to the first latching protrusion 251, so that the first latching protrusion 251 has an unlocked position retracted into the working module 200 and a locked position locked in the first slot 181. It can be understood that the slider 252 is slidably installed in the housing of the working module 200 along the front-back or left-right directions of the working module 200, and the slider 252 and the first latching protrusion 251 are movably connected by a structure such as an inclined surface, a connecting rod, or a linkage groove. When the user operates the slider 252 to move along its sliding direction, the linear movement of the slider 252 is converted into the displacement of the first latching protrusion 251 in the vertical or inclined direction through this connection relationship, so that the first latching protrusion 251 can switch between the unlocked position and the locked position. When not driven by external force, the first locking protrusion 251 is in the outwardly extended locking position, fitting and locking into the first slot 181 on the main unit 100, achieving a stable connection between the working module 200 and the main unit. When the sliding member 252 is manually slid to the unlocking stroke, it causes the first locking protrusion 251 to overcome the force of the elastic reset member and retract into the working module 200, entering the unlocking position, thereby disengaging from the first slot 181, facilitating the quick disassembly of the working module 200 from the main unit. Thus, through the cooperative movement of the sliding member 252 and the first locking protrusion 251, the operating direction of the first locking protrusion 251 can be adjusted and controlled, improving the user's ease of operation in disassembling and assembling the working module 200. Alternatively, in other embodiments, a trigger can be provided on the first locking protrusion 251, which the user can directly apply to control the switching of the first locking protrusion 251 between the unlocking and locking positions.

[0110] In one embodiment, referring to Figures 16 to 18, the working module 200 is provided with a first guide cylinder 260, which extends vertically. The side wall of the first guide cylinder 260 is provided with a first through-hole 261. A first locking protrusion 251 is movably inserted through the first through-hole 261. A sliding member 252 is slidably disposed in the first guide cylinder 260 and engages with the first locking protrusion 251 through an inclined surface. Without loss of generality, an elastic element is sandwiched between the side of the first latching protrusion 251 facing away from the first passage 261 and the inner wall of the first guide cylinder 260. The first guide cylinder 260 is fixed inside the housing of the working module 200, and its side wall has a first passage 261 for the first latching protrusion 251 to pass through. The first latching protrusion 251 can reciprocate in a direction perpendicular to the axis of the first guide cylinder 260 to extend or retract. At the same time, the sliding element 252 moves up and down along the extension direction of the first guide cylinder 260 and forms a transmission connection with the first latching protrusion 251 through a mutually cooperating inclined surface structure. When the user presses down or moves the sliding element 252 up, the sliding element 252 slides along the first guide cylinder 260, and its inclined surface pushes or releases the first latching protrusion 251, causing the first latching protrusion 251 to retract laterally into the working module 200 to switch to the unlocked position, or pops out under the action of the elastic element and locks into the first slot 181 on the main unit 100 to switch to the locked position. In this way, by using the inclined plane to convert the vertical movement of the sliding member 252 into the lateral displacement of the first locking protrusion 251, on the one hand, it adapts to the user's hand posture when disassembling and assembling the operation module 200, reducing the difficulty of disassembly and assembly; on the other hand, the first locking protrusion 251 slides horizontally to lock the operation module 200 and the main unit 100 at least vertically.

[0111] Specifically, in this embodiment, referring to Figures 17 and 18, the first latching protrusion 251 has a guide opening 253. The side wall of the guide opening 253 away from the first through-hole 261 is configured as a first guide inclined wall 254. The slider 252 is slidably inserted through the guide opening 253 and slidably abuts against the first guide inclined wall 254. It can be understood that the guide opening 253 is disposed through the first latching protrusion 251 along the sliding direction of the slider 252, and the slider 252 always maintains surface contact or line contact with the first guide inclined wall 254 during its sliding process. When the slider 252 slides vertically along the first guide cylinder 260, its outer surface abuts against and moves relative to the first guide inclined wall 254. This exerts a lateral force on the first locking protrusion 251 through the inclined surface, causing the first locking protrusion 251 to overcome the elastic force of the elastic element and retract inward, disengaging from the first slot 181 on the main unit 100, thus unlocking. Conversely, when the slider 252 slides in the opposite direction or releases external force, the first locking protrusion 251 resets outward under the action of the elastic reset element. The first guide inclined wall 254 also pushes the slider 252 in the opposite direction to fine-tune its position, ensuring that the first locking protrusion 251 reliably engages with the first slot 181, completing the locking. This improves the integration of the movable connection between the first locking protrusion 251 and the slider 252. Furthermore, by having the slider 252 pass through the guide opening 253, the direction of the force exerted by the slider 252 on the guide inclined wall is consistent with the direction of movement of the first locking protrusion 251, thereby ensuring the stability of the first locking protrusion 251 when switching between the unlocked and locked positions. Of course, in other embodiments, the first card protrusion 251 may be provided on the side, and a slope that cooperates with the slider 252 may be provided at that position.

[0112] In one embodiment, referring to Figures 17 and 18, a limiting protrusion 262 is provided inside the first guide cylinder 260, and a second positioning groove 255 is recessed in the slider 252. The limiting protrusion 262 is slidably connected to the second positioning groove 255 vertically. In the unlocked position and the locked position, the limiting protrusion 262 abuts against the two vertically opposite groove walls of the second positioning groove 255, respectively. It can be understood that when the slider 252 slides up and down in the first guide cylinder 260 to drive the first locking protrusion 251 to switch positions, the limiting protrusion 262 moves relative to the second positioning groove 255 accordingly, and abuts against the two vertically opposite groove walls of the second positioning groove 255 when the slider 252 reaches the two extreme positions. Specifically, when the slider 252 is in the unlocked position, causing the first latching protrusion 251 to retract into the working module 200, the limiting protrusion 262 abuts against the lower wall of the second positioning groove 255; while when the slider 252 is in the locked position, causing the first latching protrusion 251 to extend and engage with the first latching groove 181 of the main unit, the limiting protrusion 262 abuts against the upper wall of the second positioning groove 255. Thus, through the cooperation of the limiting protrusion 262 and the limiting groove, not only is the stroke of the slider 252 limited, preventing excessive sliding or disengagement from the guide cylinder, but it also provides the user with clear positional feedback, ensuring that the working module 200 can be accurately positioned during installation or disassembly.

[0113] In one embodiment, referring to Figures 16 to 18, the working module 200 is provided with a handle portion 270, a first latching protrusion 251 and a slider 252 are mounted on the handle portion 270, and the slider 252 is exposed at the lower part of the handle portion 270. It should be noted that the lower part of the handle portion 270 is also the lower part of the first guide cylinder 260, and the lower part of the first guide cylinder 260 is open so that the slider 252 can be exposed. The handle 270 not only serves as a grip for the user to hold and move the work module 200, but also acts as a mounting carrier for the first latch 251 and the slider 252, integrating the second connecting structure 210 into the area of ​​the work module 200. Specifically, the first latch 251 and the slider 252 are both mounted inside the handle 270 or on its structural frame, with the slider 252 at least partially exposed on the lower outer surface of the handle 270. This allows the user to trigger the unlocking or locking action by flicking the slider 252 upwards with their thumb or fingers while holding the handle 270. This highly overlaps the operation positions of the unlocking and gripping actions, enabling the disassembly, assembly, and transport of the work module 200 to be completed in a single action, without needing to change the grip or find an additional operating position, thus improving the convenience and efficiency of replacing the work module 200. Furthermore, since the first latch 251 and the slider 252 are integrated within the handle 270, it saves internal space within the work module 200 and reduces the risk of bumps or cleaning dead zones caused by external protruding structures. Of course, in other embodiments, the upper part of the slider 252 may be exposed above the upper part of the first guide cylinder 260.

[0114] Further, in this embodiment, referring to Figures 12 and 16, the operating module 200 includes two handles 270 respectively disposed on the left and right sides. The main unit 100 has first slots 181 respectively provided on the left and right sides of the two handles 270 along the front-back direction. It can be understood that the two handles 270 not only facilitate user gripping with both hands or grasping with one hand, improving the stability of handling and operation, but also serve as the mounting base for the connecting mechanism. Each handle 270 integrates the aforementioned first latching protrusion 251, sliding member 252, first guide cylinder 260, and related linkage structure. When the working module 200 is installed on the host device 100, the first latches 251 on both sides simultaneously engage with the first latches 181 on the corresponding side, forming a double-point symmetrical locking, which improves the overall rigidity and torsional resistance of the connection and prevents the working module 200 from deflecting, loosening or falling off under high load or vibration conditions. At the same time, since the unlocking operation can be completed independently or collaboratively by the sliding parts 252 on either side or both sides, the user can flexibly choose the operation method according to their usage habits, further improving the convenience of human-machine interaction.

[0115] In one embodiment, referring to Figure 16, the device host 100 is provided with a detection element (not shown) located in the first slot 181 to detect the first latching protrusion 251. Without loss of generality, the detection element can specifically be a microswitch, Hall sensor, photoelectric sensor, or pressure contact, etc., and its position is configured such that when the first latching protrusion 251 is fully engaged in the first slot 181 and in the locked position, it can be directly triggered or sensed by the first latching protrusion 251. By detecting the first latching protrusion 251 through the detection element, the device host 100 can determine in real time whether the working module 200 has been correctly installed. Once the detection element is not effectively triggered, the control system of the device host 100 will identify that the working module 200 is not connected or has an abnormal connection, and can accordingly prohibit the cleaning equipment from starting, issue a warning signal, or restrict the operation of some functions, thereby avoiding safety hazards and performance losses such as idling, water leakage, motor overload, or cleaning failure caused by the working module 200 being loose, incorrectly installed, or missing. In addition, the detection component can also be designed in combination with the electrical connectors of the operation module 200 and the equipment host 100. After the electrical connectors achieve electrical connection, the detection component further detects the first latch 251, thereby ensuring the connection reliability between the operation module 200 and the equipment host 100.

[0116] In one embodiment, referring to Figures 14 and 15, the first connecting structure 110 further includes a retractable second latching protrusion 182, and the second connecting structure 210 further includes a stop protrusion 256. The second latching protrusion 182 abuts against the upper part of the stop protrusion 256, and the second latching protrusion 182 and the first latching protrusion 251 are staggered in the front-back direction and / or the left-right direction. Without loss of generality, the second locking protrusion 182 is installed on the main unit 100 of the equipment and driven by the motor assembly. When the working module 200 is installed in place and before the cleaning equipment starts to operate, the second locking protrusion 182 extends out under the action of the motor assembly and abuts against the upper part of the stop protrusion 256 from above, forming a downward support limit, thereby restricting the tendency of the working module 200 to detach in the vertical direction and ensuring the airtightness of the air duct between the working module 200 and the main unit 100 of the equipment. At the same time, the second locking protrusion 182 and the first locking protrusion 251 are staggered in the front-back direction and / or left-right direction. Referring to the scenario of setting two first locking protrusions 251 in the above embodiment, the second locking protrusion 182 and the first locking protrusion 251 in this embodiment form a triangular layout, thereby improving the connection rigidity, vibration resistance and overall stability between the working module 200 and the main unit 100 of the equipment, and preventing shaking, displacement or accidental detachment under high load, high speed operation or complex working conditions. Furthermore, since the second locking protrusion 182 is retractable via a motor assembly, no additional operation is required. It can automatically avoid interference during the disassembly and assembly of the work module 200. Before the work module 200 is installed and the cleaning equipment is operated, the second locking protrusion 182 can abut against the stop protrusion 256 to ensure the airtightness of the air duct between the work module 200 and the main unit 100. This reduces the operational sealing requirements of the work module 200, thereby reducing the difficulty of disassembling and assembling the work module 200.

[0117] In one embodiment, referring to Figures 13 to 15, the device host 100 and the operation module 200 are provided with a communicating air inlet 191 and air outlet 192. The second locking protrusion 182 and the stop protrusion 256 are provided adjacent to the air inlet 191 and / or the air outlet 192. It can be understood that the device host 100 has an air inlet 191 and an air outlet 192, and correspondingly, the operation module 200 also has an air inlet 191 and an air outlet 192. The air inlet 191 of the operation module 200 is connected to the air outlet 192 of the device host 100, and the air outlet 192 of the operation module 200 is connected to the air inlet 191 of the device host 100 to form a complete airflow channel for supporting cleaning functions such as dust collection, air-liquid separation, or heat dissipation. The second locking protrusion 182 and the stop protrusion 256 are arranged near the air inlet 191 and the air outlet 192, so that the area can achieve efficient airflow conduction, prevent the working module 200 from tilting, shifting or failing to seal due to local force under negative pressure or high-speed airflow, and also ensure the tight fit of the air duct connection between the working module 200 and the main unit 100, avoiding suction loss or reduced cleaning efficiency caused by air leakage.

[0118] Specifically, in this embodiment, referring to Figures 14 and 15, the upper part of the stop protrusion 256 is provided with a first abutting slope 257, and the lower part of the second locking protrusion 182 is provided with a second abutting slope 183. The first abutting slope 257 and the second abutting slope 183 abut against each other. It can be understood that when the working module 200 is installed onto the host device 100, the second locking protrusion 182 extends, causing its second abutting slope 183 to abut against the first abutting slope 257 of the stop protrusion 256. The cooperation between the two slopes guides the second locking protrusion 182 to smoothly slide into place during the insertion of the working module 200, achieving automatic locking. Without loss of generality, the second abutting slope 183 is provided with a clearance opening to reduce the friction between the second abutting slope 183 and the first abutting slope 257, thereby reducing the torque requirement for driving the second locking protrusion 182. Simultaneously, the cooperation between the second abutting inclined surface 183 and the first abutting inclined surface 257, in the locked state, decomposes the vertical limiting force into a component force along the normal direction of the inclined surface, reducing the gap between the working module 200 and the main unit 100, enhancing the tightness and impact resistance of the connection interface, thereby improving the durability of the cleaning equipment. In this way, while providing reliable vertical support, it avoids assembly resistance or wear caused by rigid right-angle collisions, making the module installation process smoother and less labor-intensive, and further ensuring the stability of the working module 200 on the main unit 100. Furthermore, since the inclined surface contact has a certain tolerance, it can compensate for minor displacements caused by manufacturing tolerances or thermal expansion and contraction, further improving the stability and durability of the connection. Combined with the high airflow area adjacent to the air inlet 191 and / or air outlet 192, it can effectively resist the upward tendency of the module caused by negative pressure suction, ensuring that the air outlet is sealed and leak-proof, thereby maintaining the aerodynamic performance of the cleaning equipment.

[0119] In one embodiment, referring to Figures 13 and 16, the first connecting structure 110 includes a first limiting rib 184 extending vertically, and the second connecting structure 210 includes a first limiting groove 258 extending vertically. The widths of the first limiting rib 184 and the first limiting groove 258 in the horizontal direction gradually increase from top to bottom, and the first limiting rib 184 is engaged in the first limiting groove 258. The widths of both the first limiting rib 184 and the first limiting groove 258 in the horizontal direction gradually increase from top to bottom, forming an inverted trapezoidal or trumpet-shaped profile. When the working module 200 is installed onto the host device 100 from top to bottom, the first limiting rib 184 slides into the first limiting groove 258. While the two are vertically engaged, their gradually widening sidewalls generate an automatic centering and clamping effect during the downward positioning process. This design allows for greater tolerance during the initial installation of the working module 200, facilitating quick alignment and smooth insertion. Once fully in place, the difference in width between the upper and lower sections creates a lateral constraint, effectively limiting the swaying or shifting of the working module 200 in the left-right and front-back directions, thus improving connection stability and torsional stiffness. Furthermore, this gradually widening structure further enhances the locking force through the mutual pressure of the inclined surfaces when subjected to vibration or impact, preventing loosening.

[0120] In one embodiment, referring to Figures 12 and 13, the main unit 100 of the device is provided with a mounting position 140. A first connecting structure 110 is located in the mounting position 140. At least a portion of the bottom wall of the mounting position 140 is provided through and is used to accommodate the operation module 200. It can be understood that the mounting position 140 is a receiving area recessed at the bottom or side of the main unit, with at least a portion of its bottom wall provided through to accommodate at least a part of the operation module 200; the first connecting structure 110 is integrated into the inner peripheral wall or surrounding area of ​​the mounting position 140. When the operation module 200 is pushed into the mounting position 140 from bottom to top or in a horizontal direction, it is wholly or partially embedded inside the main unit 100 of the device, making the overall shape of the cleaning device more compact and aesthetically pleasing, reducing the risk of bumps and knocks from exposed parts, and increasing the installation volume of the operation module 200 on the main unit 100 through the vertically penetrating mounting position 140, that is, increasing the storage capacity in the operation module 200 and improving the cleaning endurance of the cleaning device. In addition, the locking mechanism of the first locking protrusion 251 and the first locking groove 181, the vertical support of the second locking protrusion 182 and the stop protrusion 256, and the guiding and positioning mechanism of the first limiting rib 184 and the first limiting groove 258 are distributed around the mounting position 140 to ensure the stability of the working module 200 after it is installed in the mounting position 140.

[0121] In one embodiment, referring to Figures 12, 13, and 16, the main unit 100 is provided with a first terminal piece 131, and the operating module 200 is provided with a second terminal piece (not shown). The first terminal piece 131 and the second terminal piece are vertically connected and electrically conductive. When the operating module 200 is inserted into the mounting position 140 of the main unit from bottom to top, the first terminal piece 131 and the second terminal piece smoothly dock with the guide structure, forming a stable and reliable electrical connection for transmitting power, control signals, or sensor data. Thus, by utilizing the direction of movement during the installation of the operating module 200, the electrical connection can be completed simultaneously with locking without additional operation, improving the convenience of disassembly and assembly operations and the system integration. Without loss of generality, the connection positions of the first terminal piece 131 and the second terminal piece are adjacent to the positions of the first latching protrusion 251 and the first latching groove 181. While ensuring the stable installation of the operation module 200, it provides a stable electrical connection foundation for the host device 100 to identify the module type and adjust the operating parameters, thereby supporting the intelligent adaptation and safe operation of multiple functional modules such as vacuuming, floor cleaning, and steaming.
