Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, specifically to a cleaning system; this disclosure also relates to a push rod device. Background Technology

[0002] With the development of social productivity, people's living standards have also improved. With their material needs met, people have begun to use various tools to reduce labor and improve their quality of life, leading to the emergence of household cleaning equipment.

[0003] For self-propelled cleaning devices, floor cleaning relies primarily on their own sensor performance and software algorithm control, which cannot achieve precise positioning and point-to-point control. Furthermore, they are prone to getting stuck in complex environments (such as near walls, corners, groups of tables and chairs, and narrow areas), making movement difficult. In addition, when users need to clean a specific area, traditional technologies typically use apps, voice commands, or gestures for control. These methods struggle to provide precise, real-time control, resulting in a poor user experience.

[0004] To address the aforementioned issues, a push rod can be installed on the self-propelled cleaning device, allowing for more precise spot cleaning through manual user control. When installing the push rod, auxiliary wheels on the self-propelled cleaning device can pop out simultaneously (e.g., 202411533414.0). These wheels provide additional support, preventing the cleaning device from tilting up at one end when operated with the push rod. However, during push rod installation, the contact surface between the self-propelled cleaning device and the push rod is pressed down by the push rod. This creates a reverse restoring force on the contact surface, which is transmitted to the unlocked push rod. This forces the user to use one hand to hold the push rod steady and apply downward force, while using the other hand to lock it, resulting in inconvenient operation and a poor user experience.

[0046] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0047] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0048] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0049] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0050] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0051] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0052] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0053] See Figures 1 to 3 This disclosure provides a cleaning system, including a self-moving cleaning device 1 and a push rod device 2. The self-moving cleaning device 1 is configured to move on its own on a working surface. Specifically, the self-moving cleaning device 1 can be a self-moving cleaning device 1 well known to those skilled in the art, such as a sweeping robot, a sweeping and mopping robot, or a floor washing robot.

[0054] like Figure 2 As shown, the self-propelled cleaning device 1 includes a main body 10, which serves as the main component of the self-propelled cleaning device 1 and primarily supports other components of the self-propelled cleaning device 1. The self-propelled cleaning device 1 also includes drive wheels 12 and cleaning components 14 mounted on the main body 10. The drive wheels 12 rotate on the working surface, thereby driving the self-propelled cleaning device 1 to move on the working surface. The cleaning components 14 can be connected to the bottom surface of the main body 10 and can be one or more of the following: suction port, roller brush, wiping disc, roller, tracked roller, mop, side brush, etc. This disclosure does not specifically limit the type of cleaning components.

[0055] The self-propelled cleaning device 1 is provided with a docking part, which can be used to install a push rod device 2. Specifically, the docking part can be provided on the main body 10. The push rod device 2 is configured to be detachably connected to the docking part, so as to push the self-propelled cleaning device 1 to move on the working surface, at least by means of the push rod device 2. Specifically, as Figure 2As shown, when the self-moving cleaning device 1 is set up independently, that is, when it is separated from the push rod device 2, the self-moving cleaning device 1 can drive the cleaning component 14 to clean the working surface through self-movement. Figure 3 As shown, when the push rod device 2 is connected to the docking part, the user can push the push rod device 2 to control the movement of the self-moving cleaning device 1, thereby enabling precise control of the self-moving cleaning device 1 to enter more complex environments (such as walls, corners, groups of tables and chairs, narrow areas, etc.) for cleaning.

[0056] This disclosure incorporates a detachable push rod device 2 on the self-moving cleaning device 1. This allows the self-moving cleaning device 1 to be detached from the push rod device 2 for automatic large-area cleaning controlled by an algorithm, or connected to the push rod device 2 for more precise spot cleaning controlled manually by the user. This disclosure achieves both manual control and precise cleaning while retaining the original automatic cleaning function of the self-moving cleaning device 1, thus improving the user experience. Users can achieve both routine self-moving cleaning and manual spot cleaning with a single cleaning device, eliminating the need to purchase two devices and reducing acquisition costs.

[0057] The push rod device 2 includes a base 21 and a push rod assembly, wherein the base 21 is configured to be detachably connected to the docking portion. (Reference) Figure 1 , Figure 11 and Figure 12 The base 21 is provided with protruding insertion parts 26. In one specific embodiment of this disclosure, there may be two insertion parts 26, which are provided on both sides of the bottom of the base 21. The docking part is a docking groove 11 provided on the top end face of the self-moving cleaning device 1. When there are two insertion parts 26, there are also two docking grooves 11. The two docking grooves 11 are configured to correspond and cooperate with the two insertion parts 26 respectively, and the insertion parts 26 are configured to be detachably connected to the docking grooves 11. When it is necessary to install the push rod device 2, the user can align the two insertion parts 26 with the two docking grooves 11 respectively, and insert the insertion parts 26 into the docking grooves 11. After insertion, further fixation is performed, thus installing the push rod device 2 onto the self-moving cleaning device 1. When it is necessary to disassemble the push rod device 2, the user only needs to release the fixation and then pull the push rod device 2 upward, thereby pulling the insertion parts 26 out of the docking grooves 11, thus detaching the push rod device 2 from the self-moving cleaning device 1.

[0058] like Figure 1As shown, the docking groove 11 of this disclosure is disposed on the top end face of the main body 10. It is understood that in the normal operating state of the self-moving cleaning device 1, its top end face is an easily accessible surface facing upwards, allowing the user to intuitively see the position of the docking groove 11 from above, thus facilitating alignment of the insertion part 26 and installation of the push rod device 2. From a top-down view, the docking groove 11 can be positioned between the central axis of the main body 10 and the cleaning component 14. This ensures that when the push rod device 2 is connected to the self-moving cleaning device 1, the force applied by the user through the push rod device 2 to drive the self-moving cleaning device 1 is located between the central axis of the main body 10 and the cleaning component 14, avoiding the risk of tilting or tipping due to torque and ensuring operational stability during manual cleaning.

[0059] In one embodiment of this disclosure, the push rod assembly is rotatably connected to the base 21 and configured to move relative to the base 21 between an upright state and an inclined state. In one embodiment of this disclosure, reference... Figures 3 to 6 The push rod assembly includes a universal joint assembly 23 at the bottom and a push rod 22 connected to the universal joint assembly 23. The push rod 22 is configured to be universally connected to the base 21 via the universal joint assembly 23. When the push rod assembly is in an upright state, the push rod 22 is perpendicular to the working surface, which is not convenient for the user to push and clean. Therefore, the user can operate the push rod 22 to rotate relative to the base 21 according to the actual cleaning needs, thereby adjusting it to an inclined state that is not perpendicular to the working surface and has a certain angle, so that the user can manually control the self-moving cleaning device 1 for precise cleaning through the push rod device 2.

[0060] like Figure 6 As shown, the base 21 may include an upper housing 211 and a lower housing 212, which together form the outer shell of the base 21. The aforementioned two insertion portions 26 may be disposed on the bottom surface of the lower housing 212. The base 21 also includes a first fixing member 215, which is used to fix the universal joint assembly 23 to the upper housing 211, and the upper part of the universal joint assembly 23 can extend through the top of the upper housing 211, thereby facilitating the connection of the push rod 22.

[0061] Specifically, in this embodiment, the push rod 22 can be detachably connected to the universal joint assembly 23, such as... Figure 4As shown, in a specific embodiment of this disclosure, the bottom end of the push rod 22 can be fitted into the sleeve at the top of the universal joint assembly 23. A spring clip 221 can be provided on the bottom end of the push rod 22, and a locking slot 231 can be provided on the sleeve wall at the top of the universal joint assembly 23 corresponding to the spring clip 221. During installation, the user inserts the bottom end of the push rod 22 into the sleeve at the top of the universal joint assembly 23. The inner wall of the sleeve compresses the spring clip 221. When fully inserted, the spring clip 221 automatically pops out from the locking slot 231, thereby connecting the push rod 22 to the universal joint assembly 23. During disassembly, the user simply presses the spring clip 221 and simultaneously pulls the push rod 22 upwards to detach it from the universal joint assembly 23. This disclosure modularizes and miniaturizes the push rod device 2, allowing for user-friendly assembly and disassembly, facilitating storage, packaging by the manufacturer, and parts replacement by the user.

[0062] Furthermore, to enhance the user experience, the push rod 22 can be constructed as a telescopic rod, allowing the user to adjust its length according to their height and operating habits. When storing, the push rod 22 can be retracted to its shortest state, saving storage space. A handle 27 can be provided at the end of the push rod 22 furthest from the universal joint assembly 23, i.e., at the top of the push rod 22. The handle 27 is shaped for comfortable gripping, allowing the user to operate the push rod device 2 by grasping the handle 27.

[0063] In one specific embodiment of this disclosure, a control module may also be provided in the handheld unit 27. For example, it can communicate with the self-moving cleaning device 1 via built-in Bluetooth and be controlled by a button assembly, thereby interacting with the self-moving cleaning device 1. The functions of the buttons may include: pairing with the self-moving cleaning device 1, controlling the cleaning component 14 to start or stop working, and controlling the suction power of the self-moving cleaning device 1. In this embodiment, after cleaning, the self-moving cleaning device 1 and the push rod device 2 can be stored together in the base station for charging and maintenance.

[0064] A reset device is provided between the push rod assembly and the base 21. The push rod assembly is configured to move to an inclined state relative to the base 21 after being subjected to an external force, and to reset to an upright state under the elastic force of the reset device after the external force is removed. In a specific embodiment of this disclosure, reference is made to... Figure 6 and Figure 11 The universal joint assembly 23 has a rotating shaft 230 on each side. The universal joint assembly 23 is configured to be rotatably connected to the base 21 via the rotating shaft 230. The reset device is a reset torsion spring 24 sleeved on the rotating shaft 230.

[0065] When the push rod assembly is subjected to an external force, the push rod 22 drives the universal joint assembly 23 to rotate, causing the push rod assembly to move to an inclined state. At this time, the return torsion spring 24 sleeved on the rotating shaft 230 deforms under the action of rotational force. When the external force is removed, the return torsion spring 24 returns to its original shape and releases its elastic force, thereby driving the universal joint assembly 23 to drive the push rod 22 back to the upright state.

[0066] After cleaning, the self-propelled cleaning device 1 can automatically drive into the base station for maintenance while detached from the push rod device 2. The base station may have a slot for storing the push rod device 2; however, the push rod device 2, being tilted, cannot be fully inserted into the slot. This disclosure solves this problem by providing a reset device between the push rod assembly and the base 21. This allows the push rod assembly to automatically reset to an upright position under the elastic force of the reset device after the external force is removed. Thus, after each use, the push rod assembly can automatically return to an upright position for easy storage, eliminating the need for manual reset by the user and improving the user experience.

[0067] In one embodiment of this disclosure, reference is made to Figures 6 to 8 A locking assembly, including a locking part 251, is provided in the base 21. The locking part 251 is configured to move relative to the base 21 between a first position and a second position. When in the first position, as... Figure 8 As shown, the locking part 251 is configured to move to lock with the self-moving cleaning device 1; when in the second position, as Figure 7 As shown, the locking part 251 is configured to move to disengage from the self-moving cleaning device 1. Specifically, a locking groove may be provided on the self-moving cleaning device 1. When the locking part 251 moves to the first position, it can be inserted into the locking groove and locked together with the self-moving cleaning device 1; when the locking part 251 moves to the second position, it can disengage from the locking groove and disengage from the self-moving cleaning device 1.

[0068] Two locking parts 251 can be provided, with the two locking parts 251 located on the left and right sides of the base 21 respectively, and the arrangement of the two locking parts 251 is symmetrical to each other. For example... Figure 5 and Figure 6 As shown, the base 21 also includes two second fixing members 216, which are respectively fixed to the lower housing 212, thereby movably mounting the two locking parts 251 to the lower housing 212. Figure 5 As shown, the horizontal plane of the free end of the locking part 251 is not higher than that of the insertion part 26, and as... Figure 9As shown, in the second position, both locking parts 251 are located inside the base 21. Therefore, when the insertion part 26 is inserted into the mating groove 11, the locking part 251 can extend into the mating groove 11 along with the insertion part 26, thereby reaching the position corresponding to the locking groove. Figure 10 As shown, when in the first position, the two locking parts 251 extend out of the base 21 at the same time, thereby extending into their respective locking grooves to lock the push rod device 2 onto the self-moving cleaning device 1.

[0069] Further, refer to Figure 5 , Figure 6 , Figure 9 and Figure 10 The locking assembly includes a rotating part 252 rotatably connected within the base 21. The rotating part 252 is configured to drive the locking part 251 to move between a first position and a second position during rotation. Two sliding grooves 2521 may be formed on the rotating part 252. Each of the two locking parts 251 has a protruding sliding member 2511 at its closest end, which extends into and slides within the two sliding grooves 2521. When the rotating part 252 rotates, the inner wall of the sliding groove 2521 drives the sliding member 2511 to slide along the extending direction of the sliding groove 2521, thereby driving the two locking parts 251 to move between the first position and the second position.

[0070] Specifically, refer to Figure 9 , Figure 10 In the view orientation, in the initial state, the locking part 251 is located in the second position. At this time, the slider 2511 on the left locking part 251 is located at the upper end of the corresponding sliding groove 2521, and the slider 2511 on the right locking part 251 is located at the lower end of the corresponding sliding groove 2521. When the rotating part 252 rotates clockwise, as... Figure 10 As shown, the inner walls of the two sliding grooves 2521 respectively push the two sliding members 2511 to slide, so that the two locking parts 251 move away from each other to the first position, thereby locking the push rod device 2 onto the self-moving cleaning device 1. Conversely, when in the first position, the sliding member 2511 on the left locking part 251 is located at the lower end of the corresponding sliding groove 2521, and the sliding member 2511 on the right locking part 251 is located at the upper end of the corresponding sliding groove 2521; when the rotating part 252 rotates counterclockwise, as Figure 9 As shown, the inner walls of the two sliding grooves 2521 respectively push the two sliding members 2511 to slide, so that the two locking parts 251 move back to the second position in a direction that brings them closer to each other, thereby unlocking.

[0071] refer to Figure 5 and Figure 6The locking assembly also includes a pusher 253 eccentrically connected to the rotating part 252. The base 21 has a mating groove 213 for the pusher 253 to protrude. The pusher 253 is configured to drive the rotating part 252 to rotate relative to the base 21 when subjected to external force. Specifically, the pusher 253 and the rotating part 252 can be fixedly connected together or be an integrally formed structure. The pusher 253, protruding from the base 21 through the mating groove 213, is used to connect with other external control components to receive external force, thereby driving the rotating part 252 to rotate and controlling the movement of the locking part 251 between a first position and a second position.

[0072] Understandably, since the rotation center of the rotating part 252 is basically located at the center of the base 21, if the user directly controls the rotation of the rotating part 252, it is easy to cause inconvenience in operation. This disclosure provides a push part 253 that is eccentrically connected to the rotating part 252, so that the user can control the rotation of the rotating part 252 by operating the push part 253. The eccentrically connected push part 253 can be located near the edge of the base 21, thereby improving the convenience of operation and enhancing the user experience.

[0073] In one embodiment of this disclosure, reference is made to Figures 4 to 6 The locking assembly also includes a rotary button 254, which is configured to connect with the actuating part 253. Specifically, as Figure 5 As shown, the portion of the push part 253 exposed from the mating groove 213 includes a first mounting member 2531, and a second mounting member 2542 is provided at the bottom of the rotary button 254. The first mounting member 2531 and the second mounting member 2542 can be snapped together to fix them together, thereby connecting the rotary button 254 to the push part 253.

[0074] refer to Figure 9 and Figure 10 A toggle part 2541 is provided on the edge of the rotary button 254, and the toggle part 2541 is configured to extend radially outward along the rotating part 252. The radially extending toggle part 2541 protrudes from the base 21, thus facilitating the user toggle the rotary button 254 via the toggle part 2541. Figure 10 As shown, when the user moves the rotary button 254 clockwise, the rotary button 254 drives the pushing part 253, which in turn drives the rotating part 252 to rotate clockwise, thereby driving the locking part 251 to move to the first position to lock with the self-moving cleaning device 1. Figure 9 As shown, when the user moves the rotary button 254 counterclockwise, the rotary button 254 drives the pushing part 253, which in turn drives the rotating part 252 to rotate counterclockwise, thereby driving the locking part 251 to move to the second position to disengage from the self-moving cleaning device 1.

[0075] In one embodiment of this disclosure, reference is made to Figure 2 and Figure 3 The self-propelled cleaning device 1 is also equipped with auxiliary wheels 13, with the direction of travel being forward. The auxiliary wheels 13 can be installed at the rear of the main body 10, while the drive wheel 12 is located in front of the auxiliary wheels 13. The auxiliary wheels 13 are configured to move between a supported position and a raised position relative to the main body 10. When in the supported position, the auxiliary wheels 13 are configured to be supported on the working surface together with the drive wheel 12; when in the raised position, the auxiliary wheels 13 are configured to be moved away from the working surface.

[0076] The self-moving cleaning device 1 disclosed herein has an automatic cleaning state detached from the push rod device 2, and a manual cleaning state connected to the push rod device 2. In the automatic cleaning state, the auxiliary wheel 13 is in the raised position; in the manual cleaning state, the auxiliary wheel 13 is in the supported position. When the user moves the self-moving cleaning device 1 on the working surface, the auxiliary wheel 13, together with the drive wheel 12, supports the main body 10 on the working surface, thus providing effective support to the rear bottom of the main body 10. This ensures that one end of the self-moving cleaning device 1 does not tilt upwards during the user's movement via the push rod device 2, ensuring that the self-moving cleaning device 1 remains firmly in contact with the working surface.

[0077] When the user inserts the connector 26 into the docking slot 11, the auxiliary wheel 13 will pop out from the raised position to the supported position, and the connector 26 will be subjected to an upward elastic force. At this time, the user needs to hold the push rod 22 firmly with one hand and apply downward force, while using the other hand to turn the rotary button 254 to lock it, which is very inconvenient. If the user does not hold it firmly, the connector 26 may be ejected from the docking slot 11, making it difficult to perform subsequent locking operations.

[0078] To solve the above problems, refer to Figure 11 and Figure 12 The plug-in portion 26 has a flange 261 on its side wall, and a snap-fit ​​portion 111 is provided at the corresponding position in the mating groove 11 to engage with the flange 261. When the plug-in portion 26 is inserted into the mating groove 11, the flange 261 engages with the snap-fit ​​portion 111, thus forming a pre-fixed structure. Under the force of the auxiliary wheel 13 popping out, the plug-in portion 26 can still be stably held in the mating groove 11, so that the user can turn the rotary button 254 to lock it in place. This disclosure improves the stability of the installation connection and enhances the user experience by providing a flange 261 on the plug-in portion 26.

[0079] In one specific embodiment of this disclosure, the flange 261 is made of an elastic material and is configured to deform under external force. During the insertion of the insertion part 26 into the mating groove 11, the flange 261 is compressed by the inner wall of the mating groove 11, and the flange 261, made of elastic material, can deform under the action of external force; until it is inserted into place, the flange 261 is located at the position of the corresponding snap-fit ​​part 111. At this time, the flange 261 is no longer subjected to external force, so it can restore its original shape under the elastic force of its own material, thereby cooperating with the snap-fit ​​part 111 and playing a pre-fixing role.

[0080] In another specific embodiment of this disclosure, the flange 261 has an internal cavity, which is configured to compress when the flange 261 is subjected to an external force and to recover its original shape after the external force is removed. The outer wall of the flange 261 encloses the cavity, and this outer wall can be made of an elastic material. During the insertion of the insertion part 26 into the mating groove 11, the outer wall of the flange 261 is squeezed by the inner wall of the mating groove 11, thereby deforming and compressing the cavity; until it is inserted into place, the flange 261 is located at the position of the corresponding snap-fit ​​part 111. At this time, the outer wall of the flange 261 is no longer subjected to external force, so it can recover its original shape under the elastic force of its own material, thereby restoring the cavity. The flange 261 can cooperate with the snap-fit ​​part 111 to play a pre-fixing role.

[0081] In another specific embodiment of this disclosure, an elastic element is provided inside the flange 261. The elastic element is configured to compress the flange 261 when it is subjected to an external force, and to cause the flange 261 to return to its original shape after the external force is removed. Specifically, the elastic element can be a spring disposed in a cavity inside the flange 261, and the spring can be pre-compressed on the inner wall of the flange 261. During the process of inserting the insertion part 26 into the mating groove 11, the flange 261 will be squeezed by the inner wall of the mating groove 11, and its internal elastic element will be compressed as a result; until it is inserted into place, the flange 261 is located at the position corresponding to the snap-fit ​​part 111. At this time, the flange 261 is no longer subjected to external force, so under the elastic force of the elastic element, the flange 261 can return to its original shape, thereby cooperating with the snap-fit ​​part 111 and playing a pre-fixing role.

[0082] In one embodiment of this disclosure, reference is made to Figure 13 and Figure 14The lower end of the flange 261 is provided with a first inclined surface 2611 that slopes inward from top to bottom, and the upper end is provided with a second inclined surface 2612 that slopes outward from top to bottom. During the insertion of the connector 26 into the mating groove 11, the locking part 111 is configured to guide and engage with the first inclined surface 2611. The locking part 111 can abut against and slide relative to the first inclined surface 2611, thereby reducing wear during insertion and extending the service life of the flange 261 and the locking part 111. Furthermore, the guiding effect of the first inclined surface 2611 makes it easier for the user to insert the connector 26.

[0083] During the process of pulling out the connector 26 from the mating slot 11, the locking part 111 is configured to guide and engage with the second inclined surface 2612. The locking part 111 can abut against and slide relative to the second inclined surface 2612, thereby reducing wear during pull-out and extending the service life of the flange 261 and the locking part 111. In addition, the guiding effect of the second inclined surface 2612 makes it easier for the user to pull out the connector 261.

[0084] In one embodiment of this disclosure, reference is made to Figure 1 and Figure 6 A shock-absorbing sheet 214 is provided on the bottom surface of the base 21 for mating with the top end face of the self-moving cleaning device 1, and / or a shock-absorbing sheet 214 is provided on the top end face of the self-moving cleaning device 1 for mating with the base 21. In this embodiment, the shock-absorbing sheet 214 can be attached to the bottom surface of the base 21. It is understood that the flat surface of the bottom surface of the base 21, except for the insertion part 26, will directly contact and mate with the top end face of the self-moving cleaning device 1. Due to manufacturing errors, the two may not fit perfectly together, and there will be a certain gap. This disclosure eliminates the gap between the two by providing a shock-absorbing sheet 214 between the bottom surface of the base 21 and the top end face of the self-moving cleaning device 1, making the assembly tighter and preventing the push rod device 2 from loosening or colliding with the self-moving cleaning device 1, thereby improving the user experience.

[0085] In one embodiment of this disclosure, a protective pad 262 is provided on the bottom end face of the insertion part 26. The protective pad 262 can be made of a soft and elastic material such as rubber, silicone, or sponge. It is understood that when the user aligns the insertion part 26 with the docking groove 11, they may not align it perfectly on the first attempt, at which point the bottom end face of the insertion part 26 may scrape against the top end face of the self-propelled cleaning device 1. This disclosure provides a soft protective pad 262 on the bottom end face of the insertion part 26, thereby preventing scratches on the top end face of the self-propelled cleaning device 1 and affecting its aesthetics, thus improving the user experience.

[0086] In one embodiment of this disclosure, the self-propelled cleaning device 1 may be provided with a first detection unit and a second detection unit. The first detection unit is used to detect whether the plug part 26 is inserted into the docking groove 11, and the second detection unit is used to detect whether the locking part 251 has moved to the first position. In practical applications, the first and second detection units may be microswitches, optocouplers, Hall switches, or infrared sensors, etc.

[0087] Taking the example where both the first and second detection units use microswitches, when the insertion part 26 is inserted into the docking slot 11 and the insertion depth is complete, the insertion part 26 can touch the first detection unit, so that the first detection unit receives a signal to determine that the insertion part 26 has been inserted in place. When the user moves the rotary button 254, causing the locking part 251 to move to the first position, the locking part 251 can touch the second detection unit, so that the second detection unit receives a signal to determine that the locking part 251 has been locked in place. Only after both of the above signals have been determined can the self-moving cleaning device 1 proceed to the next step. The dual signals ensure that the push rod device 2 is stably connected to the self-moving cleaning device 1, avoiding the risk of falling off. Furthermore, when the above signals are completed, the self-moving cleaning device 1 can provide feedback through voice, screen, lights, etc., to remind the user to proceed to the next step, giving the user a more intuitive experience.

[0088] It should be noted that the locking part 251 of this disclosure has hard limits in both the first and second positions. As long as the rotary button 254 is moved to the limit position, the locking part 251 will inevitably move accurately to the first or second position under the transmission action of the pushing part 253 and the rotating part 252. This ensures that the locking part 251 is locked in place and avoids the risk of falling off. It can be seen that even if the first detection unit and the second detection unit malfunction or fail, the self-moving cleaning device 1 will not lose its functionality and can still be stably connected to the push rod device 2 normally.

[0089] This disclosure also provides a push rod device 2, which can be the push rod device 2 in the aforementioned cleaning system. The push rod device 2 is configured to be detachably connected to a docking groove 11 on the top end face of the self-moving cleaning device 1, so as to at least push the self-moving cleaning device 1 to move on the working surface. The push rod device 2 includes a base 21 and a push rod assembly; the base 21 is provided with a protruding insertion portion 26, which is configured to be detachably connected to the docking portion; a flange 261 is provided on the side wall of the insertion portion 26; a snap-fit ​​portion 111 is provided at a position corresponding to the docking groove 11 for engaging with the flange 261. When the insertion portion 26 is inserted into the docking groove 11, the flange 261 can engage with the snap-fit ​​portion 111, thereby forming a pre-fixed structure, improving the stability during installation and connection, and enhancing the user experience.

[0090] Application scenarios

[0091] In a home setting, the self-moving cleaning device 1 can be a robot vacuum cleaner. The user purchases a robot vacuum cleaner, and the robot vacuum cleaner is equipped with a push rod device 2 as an accessory. The push rod device 2 is detachably connected to the robot vacuum cleaner.

[0092] With the push rod device 2 not installed, the robot vacuum can move automatically along its daily cleaning route, thus automatically cleaning most areas of the house. However, because there are steps between the balcony and living room in the user's home, the robot vacuum cannot easily move into the balcony for cleaning; therefore, its daily cleaning route does not include the balcony area.

[0093] When a user needs to clean the balcony, they can move the robot vacuum cleaner to the balcony, connect the push rod device 2 to the docking part on the robot vacuum cleaner, and then lock it onto the robot vacuum cleaner. In this way, the user can use the push rod device 2 to control the robot vacuum cleaner to push and pull back and forth to clean, so as to accurately and precisely remove the garbage on the balcony floor.

[0094] Specifically, during installation, the user needs to insert the connector 26 into the mating groove 11. At this time, the auxiliary wheel 13 will pop out from the raised position to the supported position, and the connector 26 will therefore be subjected to an upward elastic force. A flange 261 is provided on the side wall of the connector 26, and a snap-fit ​​part 111 is provided at the corresponding position in the mating groove 11 for engaging with the flange 261. When the connector 26 is inserted into the mating groove 11, the flange 261 can engage with the snap-fit ​​part 111, thereby forming a pre-fixed structure. Under the force of the auxiliary wheel 13 popping out, the connector 26 can still be stably held in the mating groove 11, so that the user can turn the rotary button 254 to lock it in place.

[0095] During the push-pull cleaning operation, the user can push the push rod 22 to rotate relative to the base 21 according to the actual cleaning needs, causing the push rod assembly to move to an inclined state relative to the base 21, thus making it easier for the user to push the robot vacuum cleaner for cleaning. At this time, the return torsion spring 24 sleeved on the rotating shaft 230 deforms under the action of rotational force. After the external force is removed, the return torsion spring 24 returns to its original shape and releases its elasticity, thereby driving the universal joint assembly 23 to move the push rod 22 back to the upright state.

[0096] After cleaning, the user can detach the upright push rod 2 from the robot vacuum. The robot vacuum can automatically drive into the base station for maintenance. The base station has a slot for storing the push rod 2, which fits perfectly into the slot, making it easy for the user to store. The user does not need to manually reset the push rod 2, thus improving the user experience.
