In addition, " / " in this specification generally indicates that the preceding and succeeding related objects are in an "or" relationship.

[0028] It should be noted that while terms such as "first," "second," and "third" may be used for descriptive purposes in the embodiments of this application, they should not be limited to these terms. These terms are used solely to distinguish similar subjects. For example, the first may also be called the second, and similarly, the second may also be called the first, as long as it does not deviate from the scope of the embodiments of this application.

[0029] Furthermore, the terms “includes,” “equipped with,” or any other variations thereof are intended to cover non-exclusive inclusion, and it should be noted that a product or apparatus containing a set of elements includes not only those elements but also other elements explicitly listed, or elements specific to those products or apparatus. Unless further limited, an element defined by the expression “includes” does not exclude the presence of other identical elements in a product or apparatus containing such element.

[0030] The following describes in detail the selectable embodiments of this application with reference to the attached drawings.

[0031] Figures 1 and 2 are schematic diagrams of an automated cleaning device according to several embodiments. As shown in Figures 1 and 2, the automated cleaning device may be a vacuum cleaning robot, a mopping / brushing robot, a window climbing robot, etc., and consists of a mobile platform 100, a sensing system 120, a control system 130, a drive system 140, a cleaning module 150, an energy system 160, and a human-machine interactive system 170.

[0032] The mobile platform 100 is configured to automatically move its operating surface in the direction of a target. The operating surface may be a surface to be cleaned by an automatic cleaning device. In some embodiments, the automatic cleaning device may be a mopping robot, which works on a floor surface, and the floor surface is the operating surface. The automatic cleaning device may be a window cleaning robot, which works on the outer surface of a building's glass, and the outer surface of the glass is the operating surface. The automatic cleaning device may be a pipe cleaning robot, which works on the inner surface of a pipe, and the inner surface of the pipe is the operating surface. For purely illustrative purposes, this application describes an example in which the automatic cleaning device is a mopping robot.

[0033] In some embodiments, the mobile platform 100 may be an autonomous mobile platform or a non-autonomous mobile platform. An autonomous mobile platform means that the mobile platform 100 itself can automatically and adaptively make operational decisions in response to unexpected environmental inputs, while a non-autonomous mobile platform itself cannot adaptively make operational decisions in response to unexpected environmental inputs but can operate according to predetermined procedures or certain logic. Accordingly, if the mobile platform 100 is an autonomous mobile platform, the target direction may be autonomously determined by the automatic cleaning device, while if the mobile platform 100 is a non-autonomous mobile platform, the target direction may be set by the system or manually. If the mobile platform 100 is an autonomous mobile platform, it consists of a forward-facing portion 111 and a rear-facing portion 110.

[0034] The sensing system 120 includes a position determination device 121 located above the mobile platform 100, a buffer 122 located on the forward portion 111 of the mobile platform 100, a cliff sensor 123 located at the bottom of the mobile platform, and sensing devices such as an ultrasonic sensor (not shown), an infrared sensor (not shown), a magnetometer (not shown), an accelerometer (not shown), a gyroscope (not shown), and an odometer (not shown), which provide the control system 130 with various position information and movement status information of the equipment.

[0035] To more clearly describe the behavior of the automatic cleaning device, the following directions are defined. The automatic cleaning device can move on the floor surface by various combinations of movement along three mutually perpendicular axes: the lateral axis Y, the longitudinal axis X, and the central vertical axis Z, defined by the mobile platform 100. The forward drive direction along the longitudinal axis X is denoted as "forward," and the rearward drive direction along the longitudinal axis X is denoted as "rearward." The lateral axis Y extends between the right and left wheels of the automatic cleaning device along the axis center defined substantially by the center point of the drive wheel assembly 141. Here, the automatic cleaning device can rotate around the Y axis. When the forward part of the automatic cleaning device tilts upward and the rearward part tilts downward, it is called "pitch up," and when the forward part of the automatic cleaning device tilts downward and the rearward part tilts upward, it is called "pitch down." Furthermore, the automatic cleaning device can rotate around the Z axis. In front of the automatic cleaning device, when the automatic cleaning device tilts to the right of the X axis, it is called "right turn," and when the automatic cleaning device tilts to the left of the X axis, it is called "left turn."

[0036] As shown in Figure 2, cliff sensors 123 are provided on the bottom of the mobile platform 100, in front of the drive wheel assembly 141, and behind it. The cliff sensors 123 can prevent the automatic cleaning device from falling when it is reversing, thus preventing damage to the automatic cleaning device. "Front" refers to the same side as the direction of travel of the automatic cleaning device, and "rear" refers to the opposite side from the direction of travel of the automatic cleaning device.

[0037] Specific types of position determination devices 121 include, but are not limited to, cameras and laser distance measuring devices (LDS).

[0038] Each assembly in the sensing system 120 may operate independently or may work together to achieve more precise purposes and functions. The cliff sensor 123 and ultrasonic sensor can identify the surface to be cleaned, determine the physical characteristics of the surface to be cleaned, including the surface material and cleanliness, and make more accurate determinations in combination with a camera, laser rangefinder, etc.

[0039] For example, an ultrasonic sensor may be used to determine whether the surface to be cleaned is carpet. If the ultrasonic sensor determines that the surface to be cleaned is made of carpet material, the control system 130 may control the automatic cleaning device to perform cleaning in carpet mode.

[0040] A buffer 122 is provided on the forward portion 111 of the mobile platform 100, and when the drive wheel assembly 141 propels the automatic cleaning device across the floor surface during the cleaning process, the buffer 122 detects one or more events (or objects) in the travel path of the automatic cleaning device via a sensor system, such as an infrared sensor. The automatic cleaning device may, in response to the events (or objects) detected by the buffer 122, such as obstacles or walls, control the drive wheel assembly 141 to move away from, for example, an obstacle.

[0041] The control system 130 is located on a circuit board within the mobile platform 100 and includes a central processing unit and an application processor that communicate with non-temporary memory such as a hard disk, flash memory, and random access memory. The application processor receives environmental information sensed by the multiple sensors from the sensing system 120, obstacle information fed back from a laser rangefinder, and other information. It uses a position determination algorithm, such as SLAM, to draw an instant map of the environment in which the automatic cleaning device is installed. Based on the environmental information and the environmental map, it autonomously determines a travel path. Subsequently, it controls operations such as forward, reverse, and / or steering of the drive system 140 according to the autonomously determined travel path. Furthermore, the control system 130 can determine whether to activate the cleaning module 150 and perform a cleaning operation based on the environmental information and the environmental map.

[0042] In some embodiments, the control system 130 combines distance and speed information fed back from the shock absorber 122, cliff sensor 123, and sensing devices such as ultrasonic sensors, infrared sensors, magnetometers, accelerometers, gyroscopes, and odometers to comprehensively determine the current working state of the vacuum cleaner, such as whether it is over a threshold, stuck on a carpet, located on a cliff, stuck above or below, full of dust, or lifted. It then provides a specific next action strategy according to the different situations, ensuring that the automatic cleaning device better meets the owner's requirements and provides a better user experience. Furthermore, the control system can plan the most efficient and rational cleaning path and cleaning method according to the instant map information drawn by SLAM, thereby significantly improving the cleaning efficiency of the automatic cleaning device.

[0043] The drive system 140 can execute drive commands based on specific distance and angle information such as x, y, and θ components to operate the automatic cleaning device and make it travel across the floor surface. As shown in Figure 2, the drive system 140 includes a drive wheel assembly 141. The drive system 140 can control the left and right wheels simultaneously, and to control the operation of the device more precisely, it is preferable that the drive system 140 consists of a left drive wheel assembly and a right drive wheel assembly, respectively. The left drive wheel assembly and the right drive wheel assembly are arranged symmetrically along the transverse axis defined by the moving platform 100.

[0044] To enable the automatic cleaning device to move more stably on the floor surface or to have a higher mobility, the automatic cleaning device may include one or more steering assemblies 142. The steering assembly 142 may be a driven wheel or a drive wheel, and its structural form may be a universal wheel. The steering assembly 142 may be located in front of the drive wheel assembly 141.

[0045] The energy system 160 includes rechargeable batteries such as nickel-metal hydride batteries and lithium batteries. The rechargeable batteries are connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery voltage drop monitoring circuit, which are connected to a microcontroller control circuit. The host computer is connected to the charging pile for charging via charging electrodes located on the side or bottom of the main unit.

[0046] The human-machine interactive system 170 includes buttons on a host panel, which are available to the user for selecting functions, and may further include a display screen and / or indicator lights and / or a speaker, the display screen, indicator lights and speaker being able to show the user the current status of the device or a selection of functions, and may further include a mobile phone client program. In the case of a route navigation type automatic cleaning device, the mobile phone client can display to the user a map of the environment in which the device is installed and the location of the device, providing the user with a richer and more user-friendly set of functions.

[0047] As shown in Figure 2, the cleaning module 150 may include a dry cleaning module 151.

[0048] The dry cleaning module 151 includes a roller brush, a dust box, a fan, and an air outlet. The roller brush, which interferes to some extent with the floor surface, sweeps debris from the floor surface forward to the dust intake port between the roller brush and the dust box, and sucks it into the dust box via a gas with suction force generated by the fan that passes through the dust box. The dust removal capacity of a vacuum cleaner is characterized by its dust pickup efficiency (DPU). The DPU is influenced by the structure and material of the roller brush, the airflow utilization rate of the duct consisting of the dust intake port, dust box, fan, air outlet, and their connecting members, and the type and power of the fan, making it a complex system design issue. Compared to ordinary plug-in vacuum cleaners, improved dust removal capacity is of great significance to energy-constrained automatic cleaning devices. Improved dust removal capacity directly and effectively reduces the energy required, meaning that a machine that can clean 80 square meters of flooring on a single charge can be evolved to clean 180 square meters or more on a single charge. Furthermore, reducing the number of charging cycles significantly extends battery life, allowing users to reduce the frequency of battery replacement. More intuitive and importantly, the improved dust removal capability is the most obvious and significant user experience, allowing users to directly conclude whether the machine cleans or wipes cleanly. The dry cleaning module may further include a side brush 152 having a rotating shaft, which is at a certain angle to the floor surface and moves the debris to the roller brush area of ​​the cleaning module 150.

[0049] In some embodiments, the automatic cleaning device may further include a wet cleaning module configured to clean at least a portion of the operating surface using a wet cleaning method, wherein the wet cleaning module includes a water tank, a cleaning head, a drive unit, etc., wherein water from the water tank flows along a water circuit to the cleaning head, and the cleaning head cleans at least a portion of the operating surface under the drive of the drive unit.

[0050] In existing automatic cleaning devices, the casing layout frame structure is complex, the number of parts is large, the assembly process is lengthy and cumbersome, and the cost increases due to the addition of a top flap and flip mechanism to the automatic cleaning device, and the design of top casing decorative parts on top of the top flap. Top casing decorative parts and top flaps can serve functions such as concealing unsightly parts and protecting internal components, but they complicate the overall structure of the machine, increase costs, and affect the design space for dust boxes and other components below the top flap.

[0051] In contrast, embodiments of this application provide an automatic cleaning device without a flip cover. This simplifies the design space for the dust box and its housing cavity while simplifying unnecessary components of the automatic cleaning device. The same structure produces the same technical effects, and some of these technical effects are omitted from this specification. Specifically, this application provides an automatic cleaning device including a mobile platform 100 configured to automatically move an operating surface, as shown in Figures 3-5, the mobile platform 100 including a housing cavity 200. In some embodiments, the housing cavity 200 is located on the rearward-biased side in the forward direction of the automatic cleaning device, and the housing cavity 200 includes a first cavity 201 and a second cavity 202. The automatic cleaning device further includes a dry cleaning module including a dust box 300, the dust box 300 being detachably assembled to the housing cavity 200. Here, the first cavity 201 and the second cavity 202 are arranged sequentially adjacent to each other in the forward direction of the automatic cleaning device, and the depth of the first cavity 201 is greater than the depth of the second cavity 202. The first cavity 201 and the second cavity 202 are sequentially arranged adjacent to each other in the forward direction of the automatic cleaning device, with the larger portion of the dust box's volume and weight located closer to the center of the automatic cleaning device. This allows the dust box to be more stably positioned in the housing cavity 200, stabilizing the center of gravity of the entire cleaning device. This ensures stability during movement, turning, and obstacle crossing, preventing it from easily tipping over. Simultaneously, the dust box housing and the dust box top cover are integrated into a single structure. The dust box top cover functions as part of the top surface of the moving platform and is flush with the rest of the top surface of the moving platform. This eliminates the need for the flip cover structure of conventional cleaning devices. Furthermore, the dust intake port, located approximately in the center of the bottom of the cleaning device, can be easily aligned directly with the dust box. This allows dust to enter the dust box directly from the intake port, reducing the movement of dust into the device and preventing dust contamination inside the device.The depth of the first cavity 201 is greater than the depth of the second cavity 202, allowing the dust box and dust box top cover to be housed in separate structures, facilitating the integrated design of the dust box top cover. A dust intake port 203 is provided at the bottom of the front side wall of the first cavity 201, and an air outlet 208 is provided on the rear side wall of the connection between the first cavity 201 and the second cavity 202. The air outlet 208 has a grille structure. A fan is housed in the space below the second cavity 202, and the fan is supported by a fan bracket. In some embodiments, the air outlet 208 constitutes part of the fan bracket, and an exhaust port 204 is provided on the rear side wall of the mobile platform 100. Under the suction force of the fan, dust enters the dust box 300 from the dust intake port 203, the airflow is filtered by the dust box filter, and then discharged from the exhaust port 204.

[0052] In some embodiments, the dust box 300 includes a containment section 301 and a top cover 302 located above the containment section 301, the top cover 302 being fixedly connected to the containment section 301. Methods of fixed connection include, but are not limited to, adhesive bonding, welding, integral molding, bolting, and fastening. The containment section 301 is used to contain the dust sucked in from the dust intake port 203, and the appearance of the containment section 301 is substantially consistent with the first cavity 201.

[0053] The roller brush, which makes some contact with the floor surface, sweeps up debris from the floor surface, and under the negative pressure airflow generated by the fan, it is wound in front of the dust collection port 203 between the roller brush and the dust box 300. Then, the airflow with suction force generated by the fan passes through the dust box 300 and sucks the debris into the dust box 300. The debris is then isolated inside the dust box 300 by the filter 500, and filtered air flows into the fan.

[0054] In some embodiments, the housing section 301 of the dust box 300 has a first opening 3011 located at the front of the dust box 300. The first opening 3011 is positioned to align with the dust collection port 203. The housing section 301 has a second opening 3012 located at the rear of the dust box. The filter 500 is provided in the second opening 3012, which is connected to the air outlet 208. The filter 500 and the box body of the dust box 300 are detachably connected, making it easy to attach, detach, and clean the filter. Here, the front side refers to the side in the X direction that is aligned with the forward direction of the automatic cleaning device after the dust box 300 has been assembled in the housing cavity 200, and the rear side refers to the side in the X direction that is opposite to the forward direction of the automatic cleaning device.

[0055] In some embodiments, the top cover 302 includes a first portion 3021 that covers the housing 301 and a second portion 3022 that protrudes from the housing 301 and extends outward. When the dustbin 300 is assembled into the housing cavity 200, the housing 301 and the first portion 3021 of the top cover 302 are housed in the first cavity 201, and the second portion 3022 of the top cover 302 is housed in the second cavity 202. The top cover 302 substantially matches the top portion of the first cavity 201 and the structure of the second cavity 202. This ensures that the dust box 300 is stably mounted within the housing cavity 200, preventing the dust box from shaking due to vibrations during the automatic cleaning device's operation. At the same time, the dust box top cover can just cover the housing and fan positions, and the top surface of the dust box top cover is nearly horizontal with the top surface of the moving platform, ensuring the flatness of the outer surface of the automatic cleaning device, improving the overall coordination of the appearance, providing more spatial options for the design of each component, including the housing, on the underside of the top cover, making it convenient to position different components, improving the selectivity of the dust box volume, allowing specific sizes to be set as needed, and reducing molding costs without affecting the overall opening size of the housing cavity.

[0056] In some embodiments, the first portion 3021 of the top cover 302 includes an edge 30211 that protrudes from the edge contour of the housing and extends outward. The housing cavity 200 includes a stepped portion 205 that extends around the top edge of the housing cavity. The stepped portion 205 is configured to accommodate at least a portion of the edge 30211 and at least a portion of the outer edge of the second portion 3022. This ensures that the upper surface of the top cover is substantially coplanar with the upper surface of the moving platform. The housing cavity 200 includes a stepped portion 205 that extends around the top edge of the housing cavity, allowing the entire edge of the top cover 302 to be accommodated, and the top cover 302 is housed in the housing cavity 200 in a substantially gapless manner, preventing foreign matter from falling directly into the gaps at the edge of the dustbin and getting caught in the dustbin, while simultaneously ensuring the appearance of the top cover as the top surface of the automatic cleaning device.

[0057] In some embodiments, a support structure 3023 is provided below the second portion 3022 of the top cover 302, configured to support the second portion 3022 of the top cover. In some embodiments, the support structure 3023 is integrally molded with at least a portion of the housing 301, thereby increasing the support force of the support structure 3023 on the second portion 3022 of the top cover 302 and effectively preventing damage thereto. The support structure 3023 includes, but is not limited to, arc-shaped structures and linear structures. For example, the support structure 3023 is two symmetrically provided arc-shaped structures that substantially coincide with the outer edge contour of the second portion 3022 of the top cover 302.

[0058] In some embodiments, a groove 2021 is provided on the lower surface of the second cavity 202. The groove 2021 substantially coincides with the contour of the support structure 3023, and when the second portion 3022 of the top cover is housed in the second cavity 202, the support structure 3023 is housed in the groove 2021, so that the upper surface of the top cover 302 becomes substantially horizontal.

[0059] In some embodiments, the top cover 302 is provided symmetrically along the central axis of the automatic cleaning device in the forward direction. In some embodiments, as shown in Figures 6A to 6H, the shape of the top cover is at least one of the following or a combination thereof: D-shaped, rectangular, square, circular, elliptical, triangular, quadrilateral, pentagonal, hexagonal, heptagonal, or octagonal. By installing it symmetrically, the appearance of the device can be maintained even without being covered by an outer cover, and it is also convenient for attaching and detaching the dust box.

[0060] In some embodiments, as shown in Figure 8, the first cavity 201 includes a first locking member 701. As shown in Figure 10, the second cavity 202 includes a second locking member 72. As shown in Figures 5 and 7, the first portion of the top cover 3021 includes a first locking member 601. As shown in Figure 9A, the second portion of the top cover 3022 includes a second locking member 602. The first locking member 601 locks in cooperation with the first locking member 701, and the second locking member 602 locks in cooperation with the second locking member 72.

[0061] The above embodiment relates to a dust box for an automatic cleaning device and its mounting structure, wherein a housing cavity is provided on the rear side in the forward direction of the automatic cleaning device, and the housing cavity includes a first cavity and a second cavity, the depth of the first cavity being greater than the depth of the second cavity, and after the dust box is incorporated into the housing cavity, the upper surface of the dust box top cover is substantially coplanar with the upper surface of the moving platform, thereby simplifying the top surface structure of the automatic cleaning device, reducing production costs, and simultaneously increasing the design space of the housing cavity.

[0062] Existing automatic cleaning devices are equipped with pop-up and non-pop-up dustbins, and pop-up dustbins have top flaps and flip mechanisms. When attaching or detaching the dustbin, it is necessary to open the top flap and press the dustbin to pop it up. This embodiment requires a complex dustbin pop-up mechanism, which includes multiple parts such as springs. Repeated use of the springs reduces their elasticity, preventing the dustbin from popping up smoothly. In addition, many other parts may prevent the dustbin from popping up properly, negatively impacting its usability. Non-pop-up dustbins almost always employ a complex locking structure, and the spring assembly within it is prone to breakage due to aging. The pressing member does not feel comfortable to the touch when operated, resulting in a poor overall user experience.

[0063] In this regard, embodiments of the present application provide an automatic cleaning device without a flip cover, simplifying unnecessary elements of the automatic cleaning device while facilitating the smooth removal of the dustbin. This embodiment briefly describes some structural features compared to the above embodiment, but the same structure has similar technical effects, and some technical effects are omitted from this specification. Specifically, as shown in Figures 1 to 5 and Figure 7, the automatic cleaning device comprises a moving platform 100 configured to move automatically on an operating surface and including a housing cavity 200 located at the rear in the forward direction, and a cleaning module including a dustbin 300. The dustbin 300 is detachably assembled to the housing cavity 200. The dustbin includes a housing section 301, a top cover 302 located above the housing section, and a locking mechanism. The locking mechanism includes a first locking mechanism 610 substantially located on the central axis of the top cover, where the first locking mechanism 610 includes at least a first grommet recess 603 and a first locking member 601. The first locking member 601 is located within the first grommet recess 603, and the first locking member 601 can move elastically relative to the first grommet recess 603 under external force. The first grommet recess 603 is formed recessed downward along the edge of the first portion of the top cover, and the first grommet recess 603 provides sufficient depth in the Z direction. The height of the first locking member 601 is lower than the surface of the top cover, and the first grommet recess 603 provides sufficient elastic space in the X direction, providing sufficient space for the first locking member 601 to move elastically inward.

[0064] In some embodiments, the first locking member 601 includes a first elastic arm 6011, a first grommet portion 6012, and a first buckle portion 6013. Here, the first elastic arm 6011 extends upward from the bottom of the first grommet recess 603. The first grommet portion 6012 is provided at an end portion extending above the first elastic arm 6011. The first buckle portion 6013 extends along the lateral direction of the first elastic arm 6011. For material reduction and increased elasticity, the first elastic arm 6011 is generally substantially in a "U" shape as a whole, but is not limited to this shape structure. The first grommet portion 6012 is provided laterally above the first elastic arm 6011. The first grommet portion 6012 has a bottom surface that substantially protrudes outward and a grommet surface that extends upward along the bottom surface. The grommet surface extends to a position substantially flush with the top cover. The grommet surface may have an arc-shaped structure, that is, the projection on the horizontal plane is arc-shaped. The grommet surface facilitates receiving manual operations, and the finger shape conforms to ergonomic relationships. In some embodiments, the first buckle portion 6013 is a pair of sheet-like structures symmetrically provided along both sides of the first elastic arm 6011. To facilitate insertion of the first locking member 701, the width of the sheet-like structure decreases from the root portion to the free end portion. The first elastic arm 6011 can be formed from a general elastic material as a whole, such as plastic or organic elastic material.

[0065] In some embodiments, as shown in FIG. 8, which is an enlarged schematic view of the first locking member 701 at A in FIG. 3A, the first locking member 701 is provided at a position substantially corresponding to the first locking member 601 on the inner wall of the accommodation cavity 200, and the first locking member 601 is locked in cooperation with the first locking member 701. In some embodiments, the first locking member 701 is a pair of through holes, and the free end portion of the sheet-like structure is inserted into the through holes and locked.

[0066] In some embodiments, a first recess 206 is provided in the inner wall of the housing cavity at a position substantially corresponding to the first grommet recess 603, and the pair of through holes are provided on both sides of the first recess 206. Locking is achieved when the first locking member 601 enters the through hole, and unlocking is achieved when a finger is inserted through the first recess 206 and force is applied to pull the first locking member 601 out of the through hole. The cooperation of the first recess 206 and the first grommet recess 603 makes finger access easier and more convenient.

[0067] In some embodiments, as shown in FIG. 9A, the locking mechanism further includes a second locking mechanism 620. The second locking mechanism 620 includes a second grommet recess 605 and a second locking member 602. The second grommet recess 605 forms an inner notch, such as an arc-shaped or square-shaped notch, along substantially the midline position of the second part 3022 of the top cover, making it easy for a finger to reach for a snap operation. The second locking member 602 is located below the second grommet recess 605. The second grommet recess 605 provides sufficient space for controlling the second locking member 602 by a finger, and the second locking member 602 elastically moves inward under an external force. Specifically, the second locking member 602 includes a second elastic arm 6021, a second grommet part 6022, and a second buckle part 6023. Here, the second elastic arm 6021 is located below the second grommet recess 605. The second elastic arm 6021 includes two symmetric parts. Each second elastic arm 6021 first extends along the opening direction of the second grommet recess 605, then extends along the direction of the top cover edge, and then extends along the edge direction of the second grommet recess 605. Here, the opening direction of the second grommet recess 605 is the A direction from the center of the top cover outward as shown in FIG. 9A, and in this embodiment, it is also behind the dust box top cover. The two parts of the second elastic arm 6021 are symmetrically connected and provided in a substantially two "Z" - shaped structure. The second grommet part 6022 is connected to the two symmetrically provided parts of the second elastic arm 6021. The second grommet part 6022 is provided above the two second elastic arms. As shown in FIG. 9C, which is an enlarged view of the second grommet part in FIG. 9B and FIG. 9B's C, at the bottom of the second grommet part 6022, a bottom surface 60221 that substantially protrudes outward and a grommet surface 60222 that extends upward along the bottom surface are provided, and the grommet surface extends to a position where it is substantially in the same plane as the top cover. The grommet surface may be an arc-shaped structure, which facilitates receiving manual operation and is convenient for a finger to apply a force.In some embodiments, the second grommet portion 6022 is integrally molded with a symmetrically provided second elastic arm 6021, and the second buckle portion 6023 is provided on the laterally extended portion of the second elastic arm. The second buckle portion 6023 is provided symmetrically along both sides of a pair of the second elastic arms 6021 and is, for example, a projection or sheet-like structure extending along direction A. In some embodiments, each of the second buckle portions 6023 has a groove extending inward from its end, which prevents the entire second buckle portion from becoming too deformed and difficult to snap after it has been molded and cooled. In some embodiments, the second locking member 602 further includes a symmetrically provided connecting member 6024. The connecting member 6024 is substantially planar, with one end of the second elastic arm 6021 connected to one face of the connecting member 6024, and the other face of the connecting member 6024 connected to and fixed to the end face of a support structure. The second grommet portion 6022 is exposed from the second grommet recess 605 in the X direction. When unlocking, a finger reaches the second grommet recess 605 and presses the second grommet portion 6022, applying force inward along the X axis to the dust box and elastically contracting the second buckle portion 6023 inward. The second buckle portion 6023 pops up from the bottom of the second locking member 702, achieving unlocking. The second elastic arm 6021 as a whole is generally formed from an elastic material such as plastic or an organic elastic material.

[0068] In some embodiments, as shown in Figure 10, an enlarged view of the second locking member 702 in B of Figure 3B, the second locking member 702 is provided on the inner wall of the housing cavity 200 at a location substantially corresponding to the second locking member 602, and the second locking member 602 is locked in cooperation with the second locking member 702. The second locking member 702 is a pair of projections, and the lock is achieved by the second buckle portion 602 extending to the bottom of the second locking member 702. The projections may be flat, cylindrical, rectangular parallelepiped, etc., but are not limited to these, as long as they can engage with the second buckle portion.

[0069] In some embodiments, a second recess 207 is provided on the lower surface of the second cavity 202 at a position substantially corresponding to the second grommet recess 605, and the pair of projections are provided on the rear wall of the second cavity 202 at the same height and located above the second recess 207. The second recess 207 is configured to accommodate the dust box 300 while avoiding the second locking member 602 when the dust box 300 is placed in the housing cavity 200, and the entire dust box can be well positioned in a predetermined location in the housing cavity 200.

[0070] In some embodiments, the top cover includes a first portion that covers the housing and a second portion that protrudes from the housing and extends outward, with the second grommet recess 605 and the second locking member 602 located in the second portion of the top cover. Below the second portion of the top cover, a support structure 3023 is provided, configured to support the second portion of the top cover. The second locking member 602 is provided on the support structure 3023, and as shown in Figure 4, the symmetrically arranged support structure 3023 forms a space compressed inward in the X direction, and when the second elastic arm 6021 is connected to the symmetrically arranged support structure 3023, sufficient elastic space is provided to respond to applied inward forces.

[0071] In the dustbin lock structure described in the above embodiment, the lock structure is provided symmetrically in the front-to-back direction of the dustbin top cover. By applying force to the two elastic structures on the front and back of the dustbin with one hand, the lock can be released, preventing one side from being unlocked and causing the other side of the dustbin to pop up and tilt. At the same time, the elastic structure is simple, and elastic unlocking can be achieved by forming an elastic arm with an elastic material, thus avoiding damage to complex unlocking devices such as springs.

[0072] In some embodiments, as shown in Figure 4, the second locking mechanism 620 includes at least one first magnetic attraction module 604, the first magnetic attraction module 604 being located between the second portion of the top cover and the support structure. As shown in Figure 3A, the housing cavity includes at least one second magnetic attraction module 606 configured to work in conjunction with the first magnetic attraction module 604 to attract and lock. During application, pressing the first locking member 601 and the second grommet recess 605 by hand can retract the first locking member 601 corresponding to the dustbin, and when the dustbin is placed in the housing cavity and the hand is released, the first buckle portion 6013 of the first locking member 601 automatically pops up and is inserted into the first locking member 701, the first magnetic attraction module 604 is attracted to the second magnetic attraction module 606, and the dustbin is locked. The locking structure is simple, easy to operate, and convenient for achieving locking of the dustbin.

[0073] In some embodiments, the second locking mechanism 620 described above may include a second grommet recess 605 and a second locking member 602, or it may include a first magnetic attraction module 604, or it may include both, and is not limited to these embodiments.

[0074] Existing automatic cleaning devices require dustbins to have replaceable dustbin filters. Conventional filters generally consist of a rigid frame made of plastic or metal, with cascaded filter media placed inside the frame. The frame and the area around the filter media are then connected and sealed with dot adhesive, and a sealing strip is then attached to the frame to seal the gap between the filter and the dustbin. Consequently, conventional dustbin filter sections have a complex structure, the filter installation process is cumbersome, resulting in wasted labor and cost, and the sealing adhesives are neither economical nor environmentally friendly.

[0075] In this regard, an embodiment of the present application provides an automatic cleaning device configured to move automatically on an operating surface and comprising a moving platform including a housing cavity and a cleaning module including a dust box. The dust box is detachably attached to the housing cavity. The dust box includes a dust box filter. The dust box filter is applied to the dust box of the automatic cleaning device, and the assembly process of the dust box filter is simplified. This embodiment simplifies some structural features compared to the above embodiment, and the same structure has similar technical effects, some of which are not described here. As shown in Figures 11 and 12, the dust box filter 500 includes a soft rubber frame 501, the soft rubber frame including at least one soft rubber projection for sealing the assembly gap with the dust box during the assembly process, and a filter material 502 sleeved within the soft rubber frame 501. Here, the soft rubber frame 501 is detachably connected to the filter material 502. In some embodiments, the process of irremovably connecting the soft rubber frame 501 and the filter material 502 includes an overmolding injection process. The filter material can be pre-sleeved within the frame, and the rubber sleeve can be sleeved onto the sleeved frame combination to integrally form a plurality of desired sealing protrusions. Alternatively, a two-shot injection molding process may be used, in which the hard rubber frame body is injected first, the filter material is sleeved into the frame body, and then the soft rubber is injected to form the inner and outer sealing protrusions.

[0076] The soft rubber frame 501 may have a rectangular, square, elliptical, circular, polygonal, or other structure, and is not limited to this structure. In some embodiments, as shown in Figures 11 and 12, the soft rubber frame 501 has a rectangular structure, and the rectangular soft rubber frame includes two opposing first side walls 50111 and two second side walls 50113. The soft rubber protrusions include a first protrusion 5011 distributed on the outer circumferential surface of one of the first side walls 50111 and a second protrusion 5015 distributed on the outer circumferential surface of the other first side wall 50111, and a pair of first side walls 50111 and a pair of second side walls 50113 are formed surrounding the rectangular structure frame, and the filter material is sleeved within the rectangular structure frame.

[0077] In some embodiments, the first projection 5011 and the second projection 5015 are a continuous projection structure, for example, extending continuously from one end to the other of the outer circumferential surface of the first side wall 50111. Since the first projection 5011 and the second projection 5015 are made of soft rubber, when the dust box filter is assembled into the dust box, the first projection 5011 and the second projection 5015 are pressed together to directly seal the dust box filter 500 and the second opening 3012 of the dust box, and the second opening 3012 of the dust box is sealed in sufficient contact with the inner wall that extends substantially horizontally, replacing the conventional step of sealing via a sealing strip after the dust box filter has been installed in the dust box.

[0078] In some embodiments, as shown in Figure 14, at least one of the first and second projections is a tilt-buckle structure. The tilt-buckle structure is configured to seal the assembly gap between the soft rubber frame and the dust box and to prevent the dust box filter from falling out of the dust box. For example, the tilt-buckle structure is an arc-shaped structure, and the arc-shaped structure is inclined toward the opposite side of the assembly direction of the dust box filter. The tilt-buckle structure is convenient for the dust box filter to extend into the assembly opening of the dust box with friction during the assembly process, tilt toward the opposite side of the assembly direction, and then be pressed and sealed between the dust box filter and the dust box.

[0079] In some embodiments, the second side wall of the soft rubber frame further includes at least one third projection 5012. The third projection 5012 is distributed on the outer circumferential surface of at least one second side wall 50113 of the frame structure. The third projection 5012 may be a dispersed plurality of projections. In one embodiment, the third projection 5012 is distributed on the outer circumferential surfaces of two second side walls 50113 of the frame structure, and when the dust box filter is assembled into the dust box, the third projection 5012 on the outer circumferential surface of one second side wall 50113 of the frame structure has a slightly longer structure, extends into a recess in the dust box side wall and functions as a fastener, preventing the dust box filter from falling out. Furthermore, when assembling the dust box filter, the slightly longer third projection 5012 is first inserted into the recess in the dust box side wall, rotated around the third projection 5012, and then the other side of the dust box filter is attached to the dust box. The third projections 5012 distributed on the outer circumferential surface of another second side wall 50113 in the frame structure have a smoother structure, and when the dust box filter is assembled to the dust box, the third projections 5012 on that side are locked into the elastic structure 5013 of the side wall of the dust box by interference fit, preventing the dust box filter from falling out. Here, the elastic structure 5013 is substantially an S structure and includes an inner recess that accommodates the third projections 5012 and an outer protrusion that is locked into the third projections 5012. The outer protrusion moves elastically under external force and is locked into the third projections 5012. Figure 15 shows the mounting structure when viewing the dust box filter from the bottom end of the dust box. In some embodiments, as shown in Figures 13A and 13B, the soft rubber frame has a first rib position 510, which is provided on the outer circumferential surface of the second side wall, and is configured to prevent assembly defects such as the dust box filter being installed too deeply or too shallowly in the dust box. During the process of installing the dust box filter in the dust box, after being assembled in a predetermined position, the first rib position 510 abuts against a cushion position 5014 provided at a corresponding position on the dust box side frame, preventing further inward stretching of the filter and preventing the dust box filter from being installed too deeply in the dust box.At the same time, during the assembly process, as shown in Figure 15, if the first rib position 510 is not in contact with the pillow position 5014 of the dust box side frame, it is considered that the assembly is not in the predetermined position, thus preventing the dust box filter from being installed too shallowly in the dust box.

[0080] In some embodiments, as shown in Figures 13A and 13B, the soft rubber frame further includes an anti-mis-installation projection 509 provided on the outer circumferential surface of the second side wall and configured to prevent the dust box filter from being installed in the wrong direction. A recess is provided in the dust box at a position corresponding to the anti-mis-installation projection 509. When the dust box filter is installed correctly, the anti-mis-installation projection 509 enters the recess and the dust box filter is assembled correctly. When the dust box filter is installed in the wrong direction, the anti-mis-installation projection 509 cannot assemble the dust box filter because there is no recess on the other side of the dust box, thus preventing mis-installation by prompting the user to install the dust box filter in the wrong direction.

[0081] In some embodiments, as shown in Figures 3A and 3B, the housing cavity 200 includes a first cavity 201 and a second cavity 202. The first cavity 201 and the second cavity 202 are arranged sequentially adjacent to each other in the forward direction of the automatic cleaning device, with the depth of the first cavity 201 being greater than the depth of the second cavity 202. A dust intake port 203 is provided at the bottom of the front wall of the first cavity 201, an air outlet 208 is provided on the rear wall of the connection point between the first cavity 201 and the second cavity 202, a fan is housed in the space below the second cavity 202, and an exhaust port 204 is provided on the rear wall of the moving platform 100. Under the suction force of the fan, dust enters the dust box 300 from the dust intake port 203, the airflow is filtered by the dust box filter, and then discharged from the exhaust port 204. Here, a grille structure is provided at the air outlet 208.

[0082] As shown in Figures 11 and 12, the flexible rubber frame further includes an inner sealing lip 507. The inner sealing lip 507 is provided on the first end face 50116 of the flexible rubber frame 501 so as to surround the filter material 502 and is configured to achieve a sealed fit between the dust box filter and the assembly surface 30121 of the second opening 3012 of the dust box. As shown in Figure 14, the assembly surface 30121 of the second opening 3012 of the dust box is provided on the side of the second opening closer to the inner wall of the dust box, is substantially planar in structure, and is assembled to the flexible rubber frame by contacting the first end face 50116 of the flexible rubber frame 501. The outer sealing lip 506 is provided on the second end face 50115 of the flexible rubber frame 501 so as to surround the filter material 502 and is configured to seal the dust box filter and the edge of the air outlet 208 of the housing cavity 200. The inner sealing lip 507 and the outer sealing lip 506 are higher than the first end face 50116 or the second end face 50115 on which they are located, and after being assembled in place, the inner sealing lip 507 is pressed between the dust box filter and the assembly surface of the dust box. Because the inner sealing lip 507 is made of a flexible material, it seals the dust box filter and the assembly surface of the dust box under the action of the pressing force. When the dust box is assembled into the automatic cleaning device, the outer sealing lip 506 of the dust box filter is pressed between the dust box filter and the outside of the grille of the air outlet 208 of the housing cavity 200, sealing the dust box filter and the assembly surface of the fan bracket. As shown in Figures 3A and 3B, the side wall connecting the first cavity 201 and the second cavity 202 constitutes the assembly surface of the fan bracket, the fan is located below the second cavity 202, and the grille-type air outlet 208 is located on the side wall connecting the first cavity 201 and the second cavity 202.The inner sealing lip 507 and outer sealing lip 506 provided on the soft rubber frame 501 enable a sealed fit between the inner end face of the dust box filter 500 and the assembly surface of the air outlet of the dust box, and between the outer end face of the dust box filter 500 and the outer surface of the grille of the air outlet of the housing cavity 200. This eliminates the conventional cumbersome step of adding sealing strips to the inside and outside of the dust box filter to satisfy the airflow sealing requirements. As the soft rubber frame 501 acts as a carrier, it also includes the inner sealing lip 507 and outer sealing lip 506, which are similarly somewhat flexible, as a sealing structure. This results in tighter contact, sealing, and fitting, a better fit, a stronger sealing effect, and ensures the airtightness of the entire airflow path, thus better protecting the functions of the cleaning device, such as dust collection and dust discharge, by negative pressure.

[0083] In some embodiments, as shown in Figures 11 and 12, the soft rubber frame further includes a stepped surface 503 that extends outward along the second end face 50115 of the soft rubber frame 501, and the stepped surface 503 and the side wall of the soft rubber frame 501 form a stepped structure, which prevents the dust box filter from being seated too deeply in the dust box. During the assembly process, as shown in Figure 14, when the dust box filter enters the dust box assembly opening, the stepped surface 503 abuts against the outer edge of the dust box assembly and engages with the outer edge of the dust box, thereby preventing the dust box filter from being seated too deeply in the dust box.

[0084] In some embodiments, as shown in Figure 11, the soft rubber frame further includes a magnetic device mounting hole 504, provided on the second end face 50115 of the soft rubber frame 501, and configured to be mounted on a magnetic device to ensure that the dust box filter is installed in a predetermined position. The magnetic device may be a magnet or other electromagnetic element, and an inductive magnetic device is mounted in the magnetic device mounting hole 504. The magnetic device mounting hole 504 is deep enough to allow the magnetic device to be mounted in a fixed position inside the filter, and when the entire filter is mounted in the fixed position, it can be detected by a Hall sensor to ensure that the filter is installed in the predetermined position.

[0085] In some embodiments, as shown in Figure 11, the soft rubber frame further includes a second rib position 5041, which is provided around the magnetic device mounting hole and configured to prevent liquid from entering the magnetic device mounting hole. The second rib position 5041 tightly encloses the outer end of the magnetic device outside the magnetic device mounting hole 504, thereby preventing the magnetic device from rusting and failing. The second rib position 5041 may be made of a soft rubber material and further encloses the magnetic device when pressed.

[0086] In some embodiments, as shown in Figure 11, the soft rubber frame further includes a grommet 505 positioned to extend outward from the stepped surface 503 and configured to facilitate the removal of the dust box filter. The shape and structure of the grommet 505 are not limited and may be semicircular, square, rectangular, etc.

[0087] In some embodiments, as shown in Figure 12, the soft rubber frame further includes a hollow structure 508 provided on the first and / or second side walls of the frame and configured to reduce the overall weight of the frame. The hollow structure 508 may have a plurality of inwardly recessed stopper holes, but the structure of the stopper holes is not limited and may be circular, square, rectangular, irregular, etc.

[0088] In the automatic cleaning device described above, the dust box filter adopts a soft rubber frame design, which allows it to be directly pressed into the dust box opening during the assembly process. Simultaneously, it works in cooperation with structures such as the first projection, the inner sealing lip, and the outer sealing lip to assemble and achieve a tight seal between the filter and the assembly surface. This avoids the conventional process of manually bonding the assembly parts with dot adhesive after the filter is installed, simplifying the process, reducing the number of assembly parts, lowering costs, and being odorless and environmentally friendly as it does not require adhesive bonding.

[0089] Finally, note that each example in this specification is described incrementally, each example focuses on its differences from the others, and identical or similar parts between examples may be referenced to one another.

[0090] The above embodiments are used to illustrate the technical solutions of the present disclosure and are not limiting thereto. While the present disclosure has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in each of the above embodiments can still be modified or some of their technical features can be replaced by equivalent substitutions, and that such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of each embodiment of the present disclosure.
