[0047] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0049] It should be noted that if the embodiments of this utility model 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.

[0050] Furthermore, if the embodiments of this utility model 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 where both A and B are satisfied simultaneously. 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 by this utility model.

[0051] 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.

[0052] This utility model proposes a cleaning device.

[0053] Please refer to Figures 1 to 3 In one embodiment of this utility model, the cleaning device includes:

[0054] 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

[0055] 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.

[0056] The technical solution of this utility model involves providing a first connecting structure 110 on the main unit 100 and a second connecting structure 210 on the working module 200. The working module 200 is installed on the main unit 100 using the first and second connecting structures 110 and 210, allowing the universal component 300 to function on both the main unit 100 and the working module 200, ensuring that the working module 200 can complete the predetermined cleaning requirements. Here, the first connecting structure 110 and the second connecting structure 210 are detachably connected. After the cleaning equipment completes the current cleaning task, the connection between the first connecting structure 110 and the second connecting structure 210 is released, and another working module 200 is replaced. The second connecting structure 210 of the other working module 200 is then connected to the first connecting structure 110 of the main unit 100 to complete another cleaning task. In this way, by replacing different operation modules 200 on a single device host 100, different operation 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.

[0057] It should be noted that the universal component 300 can be electrically connected to the working module 200 to control the working module 200. For example, if the universal 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 universal component 300 to the working module 200, enabling the working module 200 to clean the external environment. For example, if the universal component 300 is configured as a fan assembly 301, the fan can act on the working module 200 through an air duct, allowing the working module 200 to suck up the dirt on the area to be cleaned. Or, the universal component 300 can only act on the main unit 100 of the equipment to satisfy the automatic operation function of the cleaning equipment, such as movement and obstacle avoidance. In addition, the directional indicators such as the first direction and the second direction mentioned in the various embodiments of this utility model refer to... Figure 1 ,when Figure 1When the posture of the cleaning equipment changes, the directional indication also changes accordingly. The descriptions of up and down direction 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 handheld vacuum cleaner, or a fully automatic cleaning robot, such as an automatic vacuum cleaner or automatic sweeper. 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.

[0058] In one embodiment, please refer to Figure 1 , Figure 5 and Figure 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 can be understood that the general-purpose component 300 is a highly compatible component, capable of independently supporting the operation of the main equipment 100 or fulfilling the common functions of various operating modules 200. Therefore, these general-purpose components 300 are placed in the main equipment 100 to reduce the cost of the operating 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 operating module 200 to remove dirt from the cleaning area, such as the 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 surrounding 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.

[0059] Correspondingly, the types of operation modules 200 are configured according to different cleaning needs. In one embodiment, please refer to... Figure 1 , Figure 5 and Figure 7The 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 using a combination of a mop or 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 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. The operation module 200 can be equipped with additional functions beyond its basic cleaning function, such as a disinfection module with roller brush cleaning to enhance the disinfection depth. Of course, in other embodiments, operation modules 200 with other cleaning functions, such as humidification modules and drying modules, can be configured according to the configuration of the general component 300.

[0060] In one embodiment, please refer to Figure 2 , Figure 5 and Figure 7 The work module 200 is connected to the main unit 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 swaying of the work module 200 on the horizontal plane, ensuring the connection stability between the work module 200 and the main unit 100, reducing swaying 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 difficulty of operation. Of course, in other embodiments, the work module 200 can also be connected to the main unit 100 via a horizontal plug-in connection, or the work module 200 can be detachably connected to the main unit 100 via a screw connection.

[0061] In one embodiment, please refer to Figures 2 to 4The first connecting structure 110 includes a vertically extending limiting rib 111, and the second connecting structure 210 includes a vertically extending limiting groove 211, with the limiting rib 111 engaged in the limiting groove 211. It can be understood that the limiting rib 111 and the 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 limiting groove 211 and the limiting rib 111 extend vertically. Through the interaction of the limiting rib 111 and the limiting groove 211, the horizontal load-bearing capacity of the connecting structure at various points along the height of the cleaning equipment is significantly improved. This allows the working module 200 to maintain a stable connection even under significant horizontal forces, preventing it from easily detaching or loosening. This ensures convenient assembly and disassembly while also enhancing 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.

[0062] Furthermore, in this embodiment, please refer to Figures 2 to 4 The spacing of the limiting ribs 111 gradually increases from top to bottom in the first direction, and the spacing of the limiting grooves 211 gradually increases from bottom to top in the first direction. The limiting ribs 111 are fitted and locked into the limiting grooves 211. The first direction is parallel to the distribution direction of the main equipment 100 and the working module 200. It can be understood that when the working module 200 is vertically inserted into the main equipment 100, due to the gradual change in the spacing of the limiting ribs 111 and the limiting grooves 211 in the first direction, their cooperation will present a progressive locking effect. As the insertion depth increases, the friction between the limiting ribs 111 and the limiting grooves 211 gradually increases, thereby achieving a more secure connection to more effectively resist the shaking between the main equipment 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 limiting rib 111 and the limiting groove 211, they can intuitively judge the connection stability of the limiting rib 111 and the limiting groove 211, thereby improving the user experience.

[0063] In one embodiment, please refer to Figure 2 , Figure 6 and Figure 8The first connecting structure 110 includes a horizontally movable latching protrusion 116, and the second connecting structure 210 includes a horizontally positioned latching groove 212, with the latching protrusion 116 fitted into the groove 212. It can be understood that when the latching protrusion 116 is fully engaged in the 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 latching protrusion 116, during the vertical insertion process of the working module 200 into the equipment host 100, the latching protrusion 116 can initially avoid the groove 212. After the working module 200 is in place, the latching protrusion 116 can then move horizontally to the groove 212 for engagement, avoiding installation difficulties caused by interference between the latching protrusion 116 and the groove 212 during insertion. Furthermore, since the 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 connections or damage due to improper installation. Of course, in other embodiments, the movable latching protrusion 116 can also be provided in the work module 200, and the latching slot 212 that engages with it can be provided in the device host 100.

[0064] Furthermore, in this embodiment, please refer to Figures 5 to 8The first connecting structure 110 also includes a guide cylinder 112 and a movable member 119. The guide cylinder 112 has a through-hole 113 in the horizontal direction. The movable member 119 is slidably inserted into the guide cylinder 112 and is movably connected to the locking protrusion 116, so as to have an unlocking position that pulls the locking protrusion 116 back into the guide cylinder 112 and a locking position that pushes the locking protrusion 116 out of the 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 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. Furthermore, the 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 guide cylinder 112 provides a stable support structure for the movable part 119 and the locking protrusion 116. For example, the guide cylinder 112 restricts the sliding direction of the movable part 119, ensuring the stability and accuracy of the locking protrusion 116 during the extension and retraction process, thereby ensuring the stability of the locking protrusion 116 in the unlocked and locked positions, and helping to prevent the first connecting structure 110 from being deformed or damaged by external forces. Of course, in other embodiments, the 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 locking protrusion 116 is locked in the slot 212, thereby ensuring the connection stability of the main unit 100 and the working module 200 in the vertical direction.

[0065] Regarding the connection method between the movable part 119 and the latching protrusion 116, in one embodiment, please refer to... Figure 5 and Figure 6The movable part 119 and the locking protrusion 116 are rotatably connected by the connecting rod 117. In the unlocked position, the rotatable connection between the connecting rod 117 and the movable part 119 is located away from the through-hole 113. In the locked position, the rotatable connection between the connecting rod 117 and the movable part 119 is located close to the through-hole 113. It can be understood that in the unlocked position, the rotatable connection between the connecting rod 117 and the movable part 119 is located away from the through-hole 113, thereby pulling the locking protrusion 116 back into the guide cylinder 112 to release the locking relationship between the locking protrusion 116 and the slot 212. In the locked position, the rotatable connection between the connecting rod 117 and the movable part 119 is located close to the through-hole 113, so that the connecting rod 117 pushes the locking protrusion 116 outward from the through-hole 113, ensuring that the locking protrusion 116 can accurately engage in the slot 212, which helps to maintain stability when the locking protrusion 116 extends outward from the guide cylinder 112. Meanwhile, the user can easily change the horizontal tilt of the connecting rod 117 by simply pushing or pulling the movable part 119, thereby pulling the locking protrusion 116 to its horizontal position and switching the locking protrusion 116 between the unlocked and locked positions. Furthermore, the two ends of the connecting rod 117 are rotatably connected to the locking protrusion 116 and the movable part 119 respectively, which helps reduce wear between the movable part 119 and the locking protrusion 116, ensuring the durability of the first connection structure 110 and the connection stability between the main unit 100 and the operating module 200.

[0066] In another implementation, please refer to Figure 7 and Figure 8 The movable component 119 and the locking protrusion 116 are provided with sliding guide inclined walls 121, the extension directions of which are inclined relative to the axial direction of the guide cylinder 112 and the extension direction of the movable component 119. It can be understood that when the movable component 119 moves along the axial direction of the guide cylinder 112, the guide inclined walls 121 on it interact with the guide inclined walls 121 on the locking protrusion 116, thereby pushing the locking protrusion 116 to move in a direction different from the axial direction of the guide cylinder 112. This allows the movable component 119 to smoothly guide the locking protrusion 116 to move horizontally during movement, ensuring the stability of the locking protrusion 116 when switching between the unlocked and locked positions. Simultaneously, the inclined arrangement of the guide inclined walls 121 causes the contact area between the locking protrusion 116 and the movable component 119 to gradually change as the movable component 119 moves, thereby dispersing friction and making the steering movement smoother. In addition, by optimizing the tilt angle and extension direction of the guide inclined 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 locking protrusion 116 and the moving part 119, thereby improving the connection stability between the main equipment 100 and the working module 200.

[0067] Specifically, in this embodiment, please refer to Figure 6 and Figure 8The guide cylinder 112 is also provided with a limiting protrusion 115, and the movable part 119 is recessed with a positioning groove 122. The limiting protrusion 115 can slide along the axial direction of the guide cylinder 112 and is connected to the positioning groove 122. In the unlocked and locked positions, the limiting protrusion 115 abuts against the corresponding groove wall of the positioning groove 122 distributed along the axial direction of the guide cylinder 112. It can be understood that the cooperation between the limiting protrusion 115 and the positioning groove 122 provides a clear definition of the movement range of the movable part 119 in the guide cylinder 112, thereby limiting the maximum movement distance of the movable part 119 in the axial direction of the guide cylinder 112, preventing the movable part 119 from exceeding the predetermined range during movement, and avoiding damage to the connection structure or the inability of the locking protrusion 116 to maintain a stable state in the unlocked or locked positions due to excessive movement. Meanwhile, when the locking protrusion 116 is in the unlocked and locked positions, the limiting protrusions 115 abut against the corresponding groove walls of the positioning grooves 122 distributed axially in the guide cylinder 112, ensuring that the moving part 119 can stop precisely when it reaches these two key positions, thereby ensuring that the locking protrusion 116 can accurately switch to the unlocked or locked position. Of course, in other embodiments, a limiting structure can also be provided inside the guide cylinder 112 to prevent the moving part from coming out of the guide cylinder 112.

[0068] In one embodiment, please refer to Figure 6 and Figure 8 The first connecting structure 110 also includes an elastic element 118, which is sandwiched between the movable element 119 and the guide cylinder 112. The elastic extension and retraction direction is parallel to the axial direction of the guide cylinder 112. In the unlocked position, the elastic element 118 is in an elastically compressed state; 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 locking protrusion 116 back to the locked state, thus simplifying the user's operation. Simultaneously, when the locking protrusion 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 determine whether the locking protrusion 116 has switched to the unlocked position, facilitating the replacement of the operating module 200. Please refer to [reference needed]. Figure 6 Regarding the movable part 119 being connected to the latch 116 via the connecting rod 117, the elastic element 118 is located between the bottom of the movable part 119 and the bottom wall of the guide cylinder 112, and elastically extends and retracts in the vertical direction; please refer to Figure 8Regarding the connection between the movable part 119 and the latching protrusion 116 via the guide ramp, the elastic element 118 is located between the inner wall of the guide cylinder 112 and the through-hole 113 and the latching protrusion 116. The elastic element 118 elastically extends and retracts in the horizontal direction. Specifically, the elastic element 118 is configured as a compression spring, a tension spring, or a spring sheet. Of course, in other embodiments, the movable part 119 can also be stably engaged with the guide cylinder 112 in both the unlocked and locked positions of the latching protrusion 116. When the user controls the latching protrusion 116 to switch between the unlocked and locked positions, the movable part 119 needs to break through the engagement relationship with the 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.

[0069] In one embodiment, please refer to Figure 1 The guide cylinder 112 has a clearance opening 114 on its side wall adjacent to the outer periphery of the cleaning device. A button 123 is provided on the movable part 119. The button 123 is slidably connected to the clearance opening 114 along the axial direction of the 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. This avoids a more obvious visual position of the cleaning device, making the entire cleaning device more concise and streamlined in appearance, without any abrupt parts or lines, thus 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 users to easily reach and operate it, avoiding the inconvenience of having to search for or move the cleaning device to access the button 123, thus improving operational convenience. Specifically, the guide cylinder 112 extends vertically, and the clearance opening 114 is located on the vertically extending side wall of the guide cylinder 112, adjacent to the outer periphery of the cleaning device. Of course, in other embodiments, the clearance 114 may also be provided at the axial end of the guide cylinder 112, and the button 123 may be located on the side wall of the cleaning device extending in the horizontal plane.

[0070] Furthermore, in this embodiment, please refer to Figure 2The guide cylinder 112 is positioned adjacent to the drive wheel 150 of the cleaning equipment. The cleaning equipment also includes a crash barrier 160 on its outer perimeter. The crash barrier 160 has a clearance opening 161 that extends parallel to and opposite to the clearance opening 114. The button 123 is exposed through the clearance opening 161. It can be understood that while the button 123 is exposed outside the crash barrier 160 through the clearance opening 161, it is actually still hidden under the protection of the crash barrier 160. This concealed installation method maintains the integrity of the crash barrier 160, allows the button 123 to be easily accessed during operation, and does not compromise the aesthetics of the crash barrier 160. Meanwhile, the 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 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.

[0071] In one embodiment, please refer to Figures 2 to 4 The first connecting structure 110 has a supporting protrusion 130 near its bottom, and the second connecting structure 210 has a relief groove 230 formed on its bottom wall. The supporting protrusion 130 is fitted 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 supporting protrusion 130 and the relief groove 230 provides direct vertical support for the working module 200, ensuring its stability in the vertical direction and preventing swaying or displacement caused by vibration, tilting, or external forces. Simultaneously, the abutment between the supporting protrusion 130 and the relief groove 230 effectively distributes the weight and force of the working module 200, helping to maintain the overall structural and performance stability of the cleaning equipment. Furthermore, the fitting connection between the supporting protrusion 130 and the relief groove 230 allows the first connecting structure 110 and the second connecting structure 210 to be tightly connected, thereby optimizing the space utilization of the equipment. Of course, in other embodiments, the limiting ribs 111 can also be set as step-like structures with smaller upper sections and larger lower sections or from top to bottom to provide vertical support for the working module 200 from the host device 100.

[0072] Furthermore, in this embodiment, please refer to Figures 2 to 4The supporting protrusion 130 is provided with a first terminal piece 131, and the clearance groove 230 is provided with a second terminal piece 220. The first terminal piece 131 and the second terminal piece 220 are inserted into each other in the vertical direction to conduct electricity. It can be understood that when the working module 200 is connected to the equipment host 100, the first terminal piece 131 and the second terminal piece 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 piece 131 and the second terminal piece 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.

[0073] In one embodiment, please refer to Figures 2 to 4 The support protrusion 130 is located 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, the detection function and the support structure are tightly integrated, 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. Furthermore, the proximity of the support protrusion 130 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 of which has a first terminal piece 131, and the other has a cliff detection component. Of course, in other embodiments, the cliff detection component can also be located in the work module 200.

[0074] In one embodiment, please refer to Figure 2 and Figure 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 turns or experiences 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.

[0075] In one embodiment, please refer to Figure 2The main unit 100 of the equipment has a recessed mounting position 140. The working module 200 includes a storage box (not shown), which is fitted into the mounting position 140 and 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, 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 snugly 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 fitting the storage box into 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.

[0076] In one embodiment, please refer to Figure 9 and Figure 10 The common component configuration is a fan assembly 301, which 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. Simultaneously, 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.

[0077] Furthermore, in this embodiment, please refer to Figure 10 and Figure 11The main air duct 170 forms a first interface 171 on the main equipment 100, and the exhaust air duct 240 forms a second interface 241 on the working module 200. The first interface 171 is inclined at an angle α relative to the horizontal plane. The first interface 171 and the second interface 241 are adapted and connected, and α satisfies: 30°≤α≤60°. At the junction of the main air duct 170 and the exhaust air duct 240, the first interface 171 is in an upward and horizontally inclined position, which is suitable for the vertical installation of the working module 200 on the main equipment 100, and can ensure 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.

[0078] In one embodiment, please refer to Figure 10 and Figure 11 At least one side of the abutment periphery of the first interface 171 and the second interface 241 is recessed with a sealing ring groove 173, and a sealing ring is provided in the sealing ring groove 173. The sealing ring is sandwiched in the abutment periphery of the first interface 171 and the second interface 241. The sealing ring is arranged in a ring around the abutment of the first interface 171 and the second interface 241, forming a sealing protection for the exhaust flow channel at the splice of the first interface 171 and the second interface 241, preventing airflow leakage at this point, and ensuring the reliability and stability of the operation of the fan assembly 301. At the same time, the sealing ring groove 173 provides an installation position for the sealing ring, which facilitates the positioning and installation of the sealing ring and also promotes the deformation of the sealing ring, thereby ensuring the sealing of the circumferential joint of 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.

[0079] Regarding the orientation of the cleaning equipment after the work module 200 has been removed, i.e., on the main unit 100 of the equipment, in one embodiment, please refer to... Figure 10 and Figure 11The first interface 171 is provided with an air guide frame 172, which is arranged in a grid-like manner within the first interface 171. It can be understood that the air guide frame 172 provides support to the first interface 171, ensuring its stability. This ensures the stability and sealing of the connection between the first interface 171 and the second interface 241 during the assembly and disassembly of the work module 200. Simultaneously, after the main unit 100 and the work module 200 are separated, the air 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 air guide frame 172 rectifies and divides the airflow from the fan body, reducing the possibility of eddies in the exhaust air duct 240 and 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.
