[0022] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the present disclosure will be described in more detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments. Based on the embodiments of the present disclosure, other embodiments obtained by those skilled in the art without creative labor are all included in the protection scope of the present disclosure.

[0023] The terms used in the embodiments of the present disclosure are used only for the purpose of describing particular embodiments and are not intended to limit the present disclosure. As used in the embodiments of the present disclosure and the appended claims, the singular forms "a," "the," and "the" are also intended to encompass the plural, and "plurality" generally includes at least two, unless the context clearly indicates otherwise.

[0024] The term "and / or" used in this specification merely describes the relationship between related objects, and there are three relationships. For example, A and / or B means that A may exist alone, A and B may exist simultaneously, or B may exist alone. In addition, " / " in this specification generally indicates that the related objects before and after it are in an "or" relationship.

[0025] In the embodiments of the present disclosure, terms such as "first," "second," and "third" may be used for explanatory purposes, but it should be understood that these terms are not intended to be limiting. These terms are used only for distinction. For example, a "first" may also be called a "second," and similarly, a "second" may also be called a "first," without departing from the scope of the embodiments of the present disclosure.

[0026] It should be noted that the terms "comprises," "has," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a product or device comprising a set of elements not only includes those elements, but also other elements explicitly listed or inherent in those products or devices. Unless further limited, an element defined as "comprising" does not exclude the presence of other identical elements in a product or device that includes said element.

[0027] Selected embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0028] 1 and 2 are schematic structural diagrams of an automatic cleaning device according to an exemplary embodiment. As shown in FIGS. 1 and 2, the automatic cleaning device may be a vacuum cleaning robot, a mopping / brushing robot, a window climbing robot, etc., and the automatic cleaning device is composed of a moving platform 100, a sensing system 120, a control system 130, a driving system 140, a cleaning module 150, an energy system 160 and a human-machine interactive system 170.

[0029] The mobile platform 100 is configured to automatically move a manipulation surface in a target direction. The manipulation 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, where the automatic cleaning device works on a floor surface, and the floor surface is the manipulation surface. The automatic cleaning device may be a window cleaning robot, where the automatic cleaning device works on the glass exterior surface of a building, and the glass is the manipulation surface. The automatic cleaning device may be a pipe cleaning robot, where the automatic cleaning device works on the interior surface of a pipe, and the interior surface of the pipe is the manipulation surface. Purely for purposes of illustration, the present disclosure will be described with reference to a mopping robot.

[0030] In some embodiments, mobile platform 100 may be an autonomous mobile platform or a non-autonomous mobile platform. An autonomous mobile platform means that mobile platform 100 itself can automatically and adaptively make operational decisions in response to unexpected environmental inputs. A non-autonomous mobile platform cannot adaptively make operational decisions in response to unexpected environmental inputs, but can operate according to a predetermined procedure or logic. Correspondingly, if mobile platform 100 is an autonomous mobile platform, the target direction may be determined autonomously by an automatic cleaning device. If mobile platform 100 is a non-autonomous mobile platform, the target direction may be set by a system or manually. If mobile platform 100 is an autonomous mobile platform, mobile platform 100 is composed of a forward-facing portion 111 and a backward-facing portion 110.

[0031] The sensing system 120 includes a positioning 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 on the bottom of the mobile platform, and sensing devices such as ultrasonic sensors (not shown), infrared sensors (not shown), magnetometers (not shown), accelerometers (not shown), gyroscopes (not shown), and odometers (not shown), and provides various position information and movement status information of the equipment to the control system 130.

[0032] To more clearly describe the behavior of the automatic cleaning device, the following directions are defined. The automatic cleaning device can move across a floor surface using various combinations of movement along three mutually perpendicular axes defined by the mobile platform 100: the lateral axis Y, the front-to-rear axis X, and the central vertical axis Z. The forward drive direction along the front-to-rear axis X is designated "forward," and the rearward drive direction along the front-to-rear axis X is designated "rear." The lateral axis Y extends between the right and left wheels of the automatic cleaning device along an axis center substantially defined by the center point of the drive wheel assembly 141. Here, the automatic cleaning device can rotate around the Y axis. When the forward-facing portion of the automatic cleaning device tilts upward and the rear-facing portion tilts downward, this is referred to as "pitch up," and when the forward-facing portion of the automatic cleaning device tilts downward and the rear-facing portion tilts upward, this is referred to as "pitch down." Additionally, the automatic cleaning device can rotate around the Z axis. When the automatic cleaning device tilts to the right of the X axis at the front of the automatic cleaning device, this is referred to as "turn right," and when the automatic cleaning device tilts to the left of the X axis, this is referred to as "turn left."

[0033] As shown in Figure 2, cliff sensors 123 are provided on the bottom of the moving platform 100, in front of and behind the drive wheel assembly 141. The cliff sensors prevent the automatic cleaning device from falling when it retreats, thereby preventing damage to the automatic cleaning device. The "front" refers to the side of the automatic cleaning device in the same direction as the direction of travel, and the "rear" refers to the opposite side of the direction of travel of the automatic cleaning device.

[0034] Specific types of position determining device 121 include, but are not limited to, a camera, a laser ranging device (LDS), and the like.

[0035] Each assembly in the sensing system 120 may operate independently or may work in concert to achieve more precise purposes and functions. The cliff sensor 123 and ultrasonic sensor identify the surface to be cleaned and determine the physical characteristics of the surface to be cleaned, including surface material, cleanliness, etc., which can be combined with a camera, laser ranging device, etc. for more accurate determination.

[0036] For example, an ultrasonic sensor may be used to determine whether the surface to be cleaned is carpeted, and if the ultrasonic sensor determines that the surface to be cleaned is carpeted, the control system 130 may control the automatic cleaning device to perform a carpet mode cleaning.

[0037] A buffer 122 is provided on the forward-facing portion 111 of the mobile platform 100, and when the drive wheel assembly 141 propels the automatic cleaning device to travel on 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, for example, an infrared sensor. In response to the event (or object), for example, an obstacle or a wall, the automatic cleaning device may control the drive wheel assembly 141 so that the automatic cleaning device moves away from the obstacle in response to the event (or object) detected by the buffer 122.

[0038] The control system 130 is provided on a circuit board within the mobile platform 100 and includes a central processing unit, an application processor, or other computing processor that communicates with a non-transitory memory, such as a hard disk, flash memory, or random access memory. The application processor receives environmental information sensed by the multiple sensors from the sensing system 120 and obstacle information fed back from a positioning device, uses a positioning algorithm, such as SLAM, to draw an instant map of the environment in which the automatic cleaning device is installed, autonomously determines a travel path based on the environmental information and the environmental map, and then controls operations such as forward movement, backward movement, 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 to perform a cleaning operation based on the environmental information and the environmental map.

[0039] Specifically, the control system 130 combines distance and speed information fed back from the buffer 122, cliff sensor 123, and other sensing devices, such as ultrasonic sensors, infrared sensors, magnetometers, accelerometers, gyroscopes, and odometers, to comprehensively determine the current operating status of the vacuum cleaner, such as whether it has crossed a threshold, climbed onto a carpet, reached a cliff, been caught on the top or bottom, the dustbin is full, or been lifted, and provides specific next operating strategies according to different situations, allowing the automatic cleaning device to better meet the owner's requirements and provide 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.

[0040] Based on specific distance and angle information, such as x, y, and θ components, the drive system 140 executes drive commands to steer the automatic cleaning device across a floor surface. As shown in FIG. 2, the drive system 140 includes a drive wheel assembly 141. The drive system 140 can simultaneously control the left and right wheels, and for more precise control of the device's operation, the drive system 140 preferably comprises a left drive wheel assembly and a right drive wheel assembly, respectively. The left drive wheel assembly and the right drive wheel assembly are symmetrically disposed along a horizontal axis defined by the mobile platform 100.

[0041] To allow the automatic cleaning device to move more stably on a floor surface or to have higher mobility, the automatic cleaning device may include one or more steering assemblies 142. The steering assemblies 142 may be driven wheels or driving wheels, and may be universal wheels. The steering assemblies 142 may be located in front of the driving wheel assemblies 141.

[0042] The energy system 160 includes a rechargeable battery such as a nickel-metal hydride battery or a lithium battery. The rechargeable battery is connected to a charge control circuit, a battery pack charging temperature detection circuit, and a battery voltage drop monitoring circuit, which are connected to a microcomputer control circuit. The host computer is connected to a charging pile via charging electrodes provided on the side or bottom of the main body for charging.

[0043] The human-machine interactive system 170 includes keys on a host panel that can be used by a user to select functions, and may further include a display screen and / or indicator lights and / or a speaker, which can display the current status or function options of the device to the user, 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 a map of the environment in which the device is installed and the location of the device to the user, thereby providing the user with a richer and more user-friendly function list.

[0044] As shown in FIG. 2, cleaning module 150 may include a dry cleaning module 151 .

[0045] The dry cleaning module 151 includes a roller brush, a dust box, a fan, and an air outlet. The roller brush, which is in contact with the floor surface to some extent, sweeps dust on the floor toward the dust suction port between the roller brush and the dust box, and then sucks it into the dust box via suction gas generated by the fan. The dust removal capacity of a vacuum cleaner is indicated by its dust pickup efficiency (DPU). DPU is affected by the structure and material of the roller brush, the wind power utilization rate of the duct consisting of the dust suction port, dust box, fan, air outlet, and their connecting components, and the type and power of the fan, making it a complex system design issue. Compared to ordinary plug-in dust vacuum cleaners, improved dust removal capacity is significant for energy-constrained automatic cleaning devices. Improving dust removal capacity directly and effectively reduces the energy required, e.g., it can evolve a machine that can clean 80 square meters of floor space on a single charge to clean more than 180 square meters on a single charge. In addition, by reducing the number of charging times, battery life is also significantly extended, allowing users to replace batteries less frequently. More intuitively and importantly, improved dust removal ability is the most obvious and significant user experience, allowing users to directly conclude whether the machine cleans or wipes clean. The dry cleaning module may further include side brushes 152 having a rotating shaft that forms a certain angle with the floor surface to move dirt to the roller brush area of ​​the cleaning module 150.

[0046] As an optional cleaning module, 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, where the wet cleaning module includes a water tank, a cleaning head, a driving unit, etc., where 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 driving of the driving unit.

[0047] Existing automatic cleaning devices have a complex casing layout frame structure, a large number of parts, a large number of assembly steps, and tedious processes. Adding a top flap and flip mechanism to the automatic cleaning device and designing a top casing decorative part on the top flap increases costs. While the top casing decorative part and top flap can conceal unsightly objects and protect internal parts, they complicate the overall machine structure, increase costs, and affect the design space for the dust box under the top flap.

[0048] In this regard, embodiments of the present disclosure provide an automatic cleaning device without a flip cover. This simplifies unnecessary components of the automatic cleaning device while expanding the design space of the dust box and its storage cavity. Since the same structure provides the same technical effects, some technical effects will not be repeated herein. Specifically, the present disclosure provides an automatic cleaning device, as shown in FIG. 3 , including a moving platform 100 configured to automatically move an operation surface and a dry cleaning module 151. The moving platform 100 includes a storage cavity 200. In some embodiments, the storage cavity 200 is located on a side biased toward the rear in the forward direction of the automatic cleaning device. The storage cavity 200 includes a first cavity 201 and a second cavity 202. The dry cleaning module 151 includes a dust box 300, and the dust box 300 is removably assembled to the storage cavity 200. Here, 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, and the depth of the first cavity 201 is deeper than the depth of the second cavity 202. The first cavity 201 and the second cavity 202 are arranged adjacent to each other in the forward direction of the automatic cleaning device, and the larger volume and weight of the entire dust box is located closer to the center of the automatic cleaning device, allowing the dust box to be more stably positioned in the receiving cavity 200, stabilizing the center of gravity of the entire cleaning device and making it more stable when moving forward, turning, crossing obstacles, etc., and less likely to tip over. At the same time, the dust box receiving part and the dust box top cover are integrated into one structure, and 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 flip cover structure of conventional cleaning devices and allows the dust suction port, located approximately in the center of the bottom of the cleaning device, to be easily aligned directly with the dust box, allowing dust to enter the dust box directly from the dust suction port, reducing the process of dust entering the interior of 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 as separate structures and facilitating an integrated design of the dust box top cover. A dust suction port 203 is provided at the bottom of the front wall of the first cavity 201, and an air outlet 208 is provided on the rear wall where the first cavity 201 and the second cavity 202 connect. The air outlet 208 has a grill structure. A fan is housed in the space below the second cavity 202 and is supported by a fan bracket. In some embodiments, the air outlet 208 forms part of the fan bracket, and an air outlet 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 through the dust suction port 203, and the airflow is filtered by the dust box filter before being discharged through the air outlet 204.

[0049] In some embodiments, the dust box 300 includes a receiving portion 301 and a top cover 302 disposed above the receiving portion 301, and the top cover is fixedly connected to the receiving portion. Methods for the fixed connection include, but are not limited to, gluing, welding, integral molding, bolting, fastening, etc. The receiving portion is used to receive dust sucked through the dust suction port 203, and the appearance of the receiving portion substantially matches the first cavity 201.

[0050] The roller brush, which interferes with the floor surface to a certain extent, sweeps up the dust on the floor surface, and under the action of the negative pressure airflow generated by the fan, the dust is wound in front of the dust suction port 203 between the roller brush and the dust box 300, and then sucked into the dust box 300 by the suction airflow generated by the fan that passes through the dust box 300, and the dust is isolated inside the dust box 300 by the filter 500, and the filtered air flows into the fan.

[0051] Typically, the accommodating section 301 of the dust box 300 has a first opening 3011 at the front side of the dust box. The first opening 3011 is aligned with the dust suction port 203. The accommodating section 301 has a second opening 3012 at the rear side of the dust box. The filter 500 is installed 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 along the forward movement direction of the automatic cleaning device after the dust box 300 is assembled in the accommodating cavity 200 in the X direction, and the rear side refers to the side opposite the forward movement direction of the automatic cleaning device in the X direction.

[0052] In some embodiments, the top cover 302 includes a first portion 3021 that covers the receiving portion 301 and a second portion 3022 that protrudes outward from the receiving portion 301. When the dust box 300 is assembled to the receiving cavity 200, the receiving portion 301 and the first portion 3021 of the top cover 302 are received in the first cavity 201, and the second portion 3022 of the top cover 302 is received in the second cavity 202. The top cover 302 substantially matches the top end portion of the first cavity and the structure of the second cavity. This allows the dust box 300 to be stably installed within the receiving cavity 200, preventing the dust box from shaking due to vibrations during the operation of the automatic cleaning device. At the same time, the top cover of the dust box can exactly cover the receiving section and the fan position, the upper surface of the dust box top cover is approximately level with the upper surface of the moving platform, ensuring the flatness of the outer surface of the automatic cleaning device and improving the overall coordination of the appearance. It provides more space options for the design of each component, including the receiving section, on the underside of the top cover, making it convenient to arrange the positions of different components, improving the volume options of the dust box, allowing specific sizes to be set as needed, and reducing molding costs without affecting the overall opening size of the receiving cavity.

[0053] In some embodiments, the first portion 3021 of the top cover 302 includes a rim 30211 that protrudes outward from the edge contour of the storage portion. The storage cavity 200 includes a step 205 that extends around the top edge of the storage cavity. The step 205 is configured to receive at least a portion of the rim 30211 and at least a portion of the outer edge of the second portion. This allows the top surface of the top cover to be substantially flush with the top surface of the moving platform. The storage cavity 200 includes the step 205 that extends around the top edge of the storage cavity, allowing the entire edge of the top cover 302 to be received. The top cover 302 is received in the storage cavity 200 in a substantially tight manner, preventing foreign objects from falling directly into the gap at the edge of the dust box and becoming caught in the dust box, while at the same time maintaining the appearance of the top cover as the top surface of an automatic cleaning device.

[0054] In some embodiments, a support structure 3023 configured to support the second portion 3022 of the top cover 302 is provided below the second portion 3022 of the top cover 302. Optionally, the support structure 3023 is integrally molded with at least a portion of the receiving portion 301, which can enhance the support force of the support structure 3023 on the second portion 3022 of the top cover 302 and effectively prevent damage thereto. The support structure 3023 can include, but is not limited to, an arc-shaped structure and a linear structure. In one embodiment, for example, the support structure 3023 is two symmetrically arranged arc-shaped structures that substantially match the outer edge contour of the second portion 3022 of the top cover 302.

[0055] In some embodiments, a groove 2021 is provided on the lower surface of the second cavity 202. The groove 2021 substantially matches the contour of the support structure 3023, so that when the second portion of the top cover is received in the second cavity, the support structure 3023 is received in the groove 2021 and the upper surface of the top cover 302 is substantially horizontal.

[0056] In some embodiments, the top cover is symmetrically arranged along the central axis of the forward movement of the automatic cleaning device. In some embodiments, as shown in Figures 6a to 6h, the top cover has at least one shape selected from the group consisting of a D-shape, a rectangle, a square, a circle, an oval, a triangle, a square, a pentagon, a hexagon, a heptagon, and an octagon, or a combination thereof. The symmetrical arrangement allows the device to maintain its appearance even without an outer cover, and also facilitates the installation and removal of the dust box.

[0057] In some embodiments, the first cavity 201 includes a first locking member 701. The second cavity 202 includes a second locking member 72. The top cover first portion 3021 includes a first locking member 601. The top cover second portion 3022 includes a second locking member 602. The first locking member 601 cooperates with the first locking member 701 to lock, and the second locking member 602 cooperates with the second locking member 72 to lock.

[0058] The above embodiment relates to a dust box of an automatic cleaning device and its mounting structure, in which an accommodating cavity is provided on the rear side of the forward direction of the automatic cleaning device, the accommodating cavity including a first cavity and a second cavity, the depth of the first cavity is deeper than the depth of the second cavity, and after the dust box is assembled into the accommodating cavity, the top surface of the dust box top cover is substantially flush with the top surface of the moving platform, thereby simplifying the top surface structure of the automatic cleaning device, reducing production costs and at the same time increasing the design space of the accommodating cavity.

[0059] Existing automatic cleaning devices are equipped with both pop-up and non-pop-up dustbins, pop-up dustbin top flaps, and flip mechanisms. When installing or removing a dustbin, the user must open the top flap and press the dustbin to pop it up. This requires a complex dustbin pop-up mechanism, which includes multiple components, such as a spring. Repeated use of the spring reduces its elasticity, preventing the dustbin from popping up smoothly. Furthermore, the numerous other components can prevent the dustbin from popping up properly, negatively impacting use. Non-pop-up dustbins often employ complex locking mechanisms, the spring assemblies of which are prone to breakage due to aging, and the pressing members are not well-fitted with the user's fingers when operating them, resulting in a poor overall user experience.

[0060] In this regard, an embodiment of the present disclosure provides an automatic cleaning device without a flip cover, simplifying unnecessary elements of the automatic cleaning device while facilitating smooth removal of the dust box. This embodiment will briefly describe some structural features compared to the above-described embodiment, but the same structure has similar technical effects, and some technical effects will not be repeated herein. Specifically, as shown in FIGS. 1 to 5 and 7 , the automatic cleaning device includes a moving platform 100 configured to automatically move on an operation surface and including a storage cavity 200 at the rear side in the forward direction, and a cleaning module including a dust box 300. The dust box 300 is detachably assembled to the storage cavity 200. The dust box includes a storage portion 301, a top cover 302 above the storage portion, and a locking mechanism. The locking mechanism includes a first locking mechanism 610 located substantially on the central axis of the top cover. Here, 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 can elastically move relative to the first grommet recess 603 under the action of an external force. The first grommet recess 603 is recessed downward along the edge of the first portion of the top cover, and provides a 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 a sufficient elastic space in the X direction, providing sufficient movement space for the first locking member 601 to elastically move inward.

[0061] In some embodiments, the first locking member 601 includes a first resilient arm 6011, a first grommet portion 6012, and a first buckle portion 6013. Here, the first resilient arm 6011 extends upward from the bottom of the first grommet recess portion 603. The first grommet portion 6012 is provided at the upwardly extending end of the first resilient arm 6011. The first buckle portion 6013 extends along the horizontal direction of the first resilient arm 6011. To reduce material and increase elasticity, the first resilient arm 6011 is generally shaped like a square, but is not limited to this shape. The first grommet portion 6012 is provided laterally above the first resilient arm 6011 and has a bottom surface that protrudes substantially outward and a grommet surface that extends upward along the bottom surface. The grommet surface extends to a position that is substantially flush with the top cover. The grommet surface may be an arc-shaped structure, i.e., the projection on the horizontal plane is arc-shaped, the grommet surface facilitates manual operation, and the finger shape is more ergonomic. In some embodiments, the first buckle portion 6013 is a pair of sheet structures symmetrically provided along both sides of the first elastic arm 6011, and the sheet structures have a width from a root portion to a free end portion ranging from large to small to facilitate insertion of the first locking member 701. The first elastic arm 6011 as a whole may be formed from a common elastic material, such as plastic or organic elastic material.

[0062] In some embodiments, as shown in Fig. 8, which is an enlarged schematic view of the first locking member in A of Fig. 3a, a first locking member 701 is provided on the inner wall of the receiving cavity 200 at a position substantially corresponding to the first locking member 601, and the first locking member 601 cooperates with the first locking member 701 to be locked. In some embodiments, the first locking member 701 is a pair of through holes, and the free ends of the seat structure are inserted into the through holes to be locked.

[0063] In some embodiments, a first recess 206 is provided in the inner wall of the receiving 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 a force is applied to pull the first locking member 601 out of the through hole. The cooperation between the first recess 206 and the first grommet recess 603 makes access operation with the finger easier and more convenient.

[0064] 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 a notch, such as an arc-shaped or square-shaped notch, on the inside along approximately the midline of the top cover second portion 3022, making it easy for a finger to reach for snapping. The second locking member 602 is located below the second grommet recess 605, which provides sufficient space for a finger to control the second locking member 602, allowing the second locking member 602 to resiliently move inward under the action of an external force. Specifically, the second locking member 602 includes a second elastic arm 6021, a second grommet portion 6022, and a second buckle portion 6023. Here, the second elastic arm 6021 is located below the second grommet recess 605 and includes two symmetrical portions, each of which first extends along the opening direction of the second grommet recess 605, then extends along the edge of the top cover, and then extends along the edge of the second grommet recess 605. Here, the opening direction of the second grommet recess 605 is direction A, which extends from the center of the top cover outward, as shown in FIG. 9a, and in this embodiment, it is also the rear of the dustbin top cover. The two portions of the second elastic arm 6021 are symmetrically connected to form an approximately two-sided "K" shape. The second grommet portion 6022 is connected to the two symmetrically arranged second elastic arms 6021. Specifically, the second grommet portion 6022 is disposed above the two second elastic arms, and as shown in Fig. 9b and Fig. 9c, which is an enlarged view of the second grommet portion at C in Fig. 9b, the bottom of the second grommet portion 6022 is provided with a bottom surface 60221 that protrudes substantially outward and a grommet surface 60222 that extends upward along the bottom surface to a position where the grommet surface is substantially flush with the top cover. The grommet surface may have an arc-shaped structure, which facilitates manual operation and allows fingers to conveniently apply force.Optionally, the second grommet portion 6022 is integrally molded with a symmetrically arranged second elastic arm 6021, and the second buckle portion 6023 is provided on a horizontally extending portion of the second elastic arm. The second buckle portion 6023 is symmetrically arranged along both sides of the pair of second elastic arms 6021, and is, for example, a protrusion or sheet structure extending along the A direction. As an optional embodiment, each second buckle portion 6023 has a groove extending inward from its end. The groove prevents excessive deformation of the second buckle portion 6023 after the entire second buckle portion is molded and cooled, making snapping difficult. Optionally, the second locking member 602 further includes a symmetrically arranged connecting member 6024. The connecting member 6024 is substantially planar. One end of the second elastic arm 6021 is connected to one surface of the connecting member 6024, and the other surface of the connecting member 6024 is connected and fixed to the end surface of the support structure. The second grommet portion 6022 is exposed from the second grommet recess 605 in the X direction, and when unlocking, a finger reaches the second grommet recess 605 and presses the second grommet portion 6022, applying force to the inside of the dust box along the X axis 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.

[0065] In some embodiments, as shown in Fig. 10, which is an enlarged view of the second locking member 702 in Fig. 3b B, a second locking member 702 is provided on the inner wall of the receiving cavity 200 at a position substantially corresponding to the second locking member 602, and the second locking member cooperates with the second locking member 602 to lock. The second locking member is a pair of protrusions, and locking is achieved when a second buckle portion 6023 enters the bottom of the second locking member 702. The protrusions may be flat, cylindrical, rectangular, or the like, but are not limited thereto, as long as they can be engaged with the second buckle portion.

[0066] In some embodiments, a second recess 207 is provided on the underside of the second cavity 202 at a position substantially corresponding to the second grommet recess 605, and the pair of protrusions 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 be accommodated away from the second locking member 602 when the dust box 300 is placed in the storage cavity 200, allowing the entire dust box to be well placed in a predetermined position in the storage cavity 200.

[0067] In some embodiments, the top cover includes a first portion covering the receiving portion and a second portion extending outward from the receiving portion, and the second grommet recess 605 and the second locking member 602 are located in the second portion of the top cover. A support structure 3023 configured to support the second portion of the top cover is provided below the second portion of the top cover. The second locking member 602 is provided on the support structure 3023. As shown in FIG. 4 , the symmetrically arranged support structures 3023 form a space compressed inward in the X direction, and when the second elastic arm 6021 is connected to the symmetrically arranged support structures 3023, a sufficient elastic space is ensured to respond to an applied inward force.

[0068] In the dustbin locking structure described in the above embodiment, the locking structures are symmetrically arranged in the front and rear directions of the dustbin top cover, and unlocking can be achieved by applying force to the two elastic structures at the front and rear of the dustbin with one hand, preventing one side of the dustbin from being unlocked and popping up, which would cause the dustbin to tilt. At the same time, the elastic structure is simple, and elastic unlocking can be achieved by forming the elastic arms out of elastic material, avoiding damage to complex unlocking devices such as springs.

[0069] In some embodiments, as shown in FIG. 4 , the second locking mechanism 620 includes at least one first magnetic attraction module 604, which is disposed between the second portion of the top cover and the support structure. As shown in FIG. 3 a, the receiving cavity includes at least one second magnetic attraction module 606 configured to cooperate with the first magnetic attraction module 604 to be attracted and locked. During application, the first locking member 601 corresponding to the dustbin can be retracted by manually pressing the first locking member 601 and the second grommet recess 605. After the dustbin is placed in the receiving cavity and 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, thereby locking the dustbin. This locking mechanism is simple and easy to operate, making it convenient for locking the dustbin.

[0070] In some embodiments, the second locking mechanism 620 as described above may be an embodiment including a second grommet recess 605 and a second locking member 602, an embodiment including a first magnetic attraction module 604, or an embodiment including both, but is not limited to these.

[0071] The dust box of an existing automatic cleaning device must be equipped with a replaceable dust box filter. Conventional filters generally have a rigid frame made of plastic or metal, a cascading filter medium inserted into the frame, and a dot adhesive is used to connect and seal the frame and the periphery of the filter medium. Then, a sealing strip is attached to the frame to seal the gap between the filter and the dust box. Therefore, the filter part of the conventional dust box has a complicated structure, the filter installation process is complicated, and labor and cost are wasted. The sealing adhesive is not economical or environmentally friendly.

[0072] In this regard, an embodiment of the present disclosure provides an automatic cleaning device, comprising: a moving platform configured to automatically move on an operating surface and including a storage cavity; and a cleaning module including a dust box. The dust box is detachably attached to the storage cavity. The dust box includes a dust box filter. The dust box filter is applied to the dust box of an automatic cleaning device, simplifying the assembly process of the dust box filter. This embodiment has some simplified structural features compared to the above-described embodiments, but the same structures have similar technical effects, and some technical effects will not be discussed here. Specifically, as shown in FIGS. 11 and 12 , a dust box filter 500 includes a soft rubber frame 501. The soft rubber frame includes at least one soft rubber protrusion 5011 for sealing the assembly gap with the dust box during assembly, and a filter medium 502 sleeved within the soft rubber frame 501. The soft rubber frame 501 is non-detachably connected to the filter medium 502. The specific process for non-detachably connecting the soft rubber frame 501 and the filter material 502 includes an overmolding injection process. The filter material can be pre-sleeved in the frame, and then a rubber sleeve can be attached to the sleeved frame combination to integrally form multiple desired sealing protrusions. Alternatively, a two-shot injection molding process can be used to first inject the hard rubber frame body, then sleeve the filter material onto the frame body, and then inject soft rubber to form the inner and outer sealing protrusions.

[0073] The soft rubber frame may have a rectangular, square, oval, circular, polygonal, or other shape, and is not limited to these shapes. In some embodiments, as shown in Figures 11 and 12, the soft rubber frame has a rectangular shape, 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. The pair of first side walls 50111 and the pair of second side walls 50113 are formed to surround the rectangular structural frame, and a filter medium is sleeved within the rectangular structural frame.

[0074] In some embodiments, the first protrusion 5011 and the second protrusion 5015 have a continuous protrusion structure, for example, the first protrusion 5011 and the second protrusion 5015 extend continuously from one end to the other end of the outer circumferential surface of the first side wall 50111. Because the first protrusion 5011 and the second protrusion 5015 are made of soft rubber, when the dust box filter is assembled into the dust box, the first protrusion 5011 and the second protrusion 5015 press together to directly seal between the dust box filter 500 and the second opening 3012 of the dust box, and the second opening 3012 of the dust box is in sufficient contact with the inner wall extending substantially along the horizontal direction to be sealed, which replaces the conventional step of sealing via a sealing strip after the dust box filter is assembled into the dust box.

[0075] In some embodiments, as shown in FIG. 14 , at least one of the first protrusion and the second protrusion has a reversible buckle structure. The reversible buckle structure is configured to seal the assembly gap between the soft rubber frame and the dust box and prevent the dust box filter from falling off the dust box. Specifically, the reversible buckle structure is an arc-shaped structure that is inclined toward the opposite side to the assembly direction of the dust box filter. The reversible buckle structure facilitates the dust box filter to extend with friction into the assembly opening of the dust box, incline toward the opposite side to the assembly direction, and then be pressed and sealed between the dust box filter and the dust box during the assembly process of the dust box filter.

[0076] In some embodiments, the second side wall of the soft rubber frame further includes at least one third protrusion 5012. The third protrusions 5012 are distributed on the outer circumferential surface of at least one second side wall 50113 of the frame structure. The third protrusions 5012 may have a dispersed multi-protrusion structure. In one embodiment, the third protrusions 5012 are distributed on the outer circumferential surfaces of the two second side walls 50113 of the frame structure. When the dust box filter is assembled to the dust box, the third protrusion 5012 on the outer circumferential surface s of one second side wall 50113 of the frame structure has a slightly elongated structure and extends into a recess in the dust box side wall to function as a fastener and prevent the dust box filter from falling off. When assembling the dust box filter, the slightly elongated third protrusion 5012 is first inserted into the recess in the dust box side wall and rotated around the third protrusion 5012, and then the other side of the dust box filter is attached to the dust box. The third protrusions 5012 distributed on the outer peripheral surface of another second side wall 50113 of the frame structure have a smoother structure. When the dust box filter is assembled to the dust box, the third protrusions 5012 on that side are tightly fitted into the elastic structure 5013 on the side wall of the dust box, preventing the dust box filter from falling off. Here, the elastic structure 5013 is essentially an S-structure, including an inner recess that accommodates the third protrusions 5012 and an outer protrusion that is engaged with the third protrusions 5012. The outer protrusion is elastically movable under the action of an external force and is engaged with the third protrusions 5012. Figure 15 shows the installation structure of the dust box filter when viewed from the bottom end of the dust box. 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 the dust box filter from being installed too deeply or too shallowly in the dust box, resulting in an assembly error. During the installation of the dust box filter in the dust box, after the dust box filter is assembled in place, the first rib position 510 abuts against a pillow position 5014 provided at a corresponding position on the dust box side frame, preventing the filter from further stretching inward and preventing the dust box filter from being installed too deeply in the dust box.At the same time, during the assembly process, if the first rib position 510 is not abutted against the pillow position 5014 of the dust box side frame, as shown in Figure 15, it is considered that it is not assembled in the specified position, so it is possible to prevent the dust box filter from being installed too shallowly in the dust box.

[0077] 13a and 13b, the soft rubber frame further includes an anti-misinstallation protrusion 509, which is provided on the outer circumferential surface of the second side wall and configured to prevent the dust box filter from being installed upside down. The dust box has a recess at a position corresponding to the anti-misinstallation protrusion 509, so that when the dust box filter is installed correctly, the anti-misinstallation protrusion 509 enters the recess and the dust box filter is assembled correctly. However, if the dust box filter is installed upside down, the other side of the dust box does not have the recess, so the anti-misinstallation protrusion 509 prevents the dust box filter from being assembled, thereby reminding the user to install the dust box filter in the wrong direction and preventing incorrect installation.

[0078] 3a and 3b, the receiving cavity 200 includes a first cavity 201 and a second cavity 202. The first cavity 201 and the second cavity 202 are adjacently arranged in front and behind in the forward direction of the automatic cleaning device, and the depth of the first cavity 201 is deeper than the depth of the second cavity 202. A dust suction port 203 is provided at the bottom of the front wall of the first cavity 201, an air outlet 208 is provided at the rear wall where the first cavity 201 and the second cavity 202 connect, a fan is accommodated in the space below the second cavity 202, and an air outlet 204 is provided at the rear wall of the moving platform 100. Under the suction force of the fan, dust enters the dust box 300 through the dust suction port 203, and the air is filtered by the dust box filter and then discharged through the air outlet 204. Here, the air outlet 208 is provided with a grill structure.

[0079] 11 and 12, the soft rubber frame further includes a sealing inner lip 507. The sealing inner lip 507 is provided on a first end surface 50116 of the soft rubber frame 501 to surround the filter medium 502 and is configured to achieve a sealing fit between the dust box filter and an assembly surface 30121 of the second opening 3012 of the dust box. As shown in FIG. 14, the assembly surface 30121 of the second opening 3012 of the dust box is provided on a side of the second opening closer to the inner wall of the dust box, has a substantially planar structure, and is abutted against the first end surface 50116 of the soft rubber frame 501 to assemble it to the soft rubber frame. A sealing outer lip 506 is provided on a second end surface 50115 of the soft rubber frame 501 to surround the filter medium 502 and is configured to seal the dust box filter with the edge of the air outlet 208 of the accommodating cavity 200. The sealing inner lip 507 and the sealing outer lip 506 are higher than the first end face 50116 or the second end face 50115 where they are located, and after being assembled in place, the sealing inner lip 507 is pressed between the dust box filter and the assembly surface of the dust box. Because the sealing inner 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 pressing force. When the dust box is assembled to the automatic cleaning device, the sealing outer lip 506 of the dust box filter is pressed between the dust box filter and the outside of the grill of the air outlet 208 of the receiving cavity 200, and seals 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 installed below the second cavity 202, and the grill-type air outlet 208 is installed on the side wall connecting the first cavity 201 and the second cavity 202.The inner sealing lip 507 and outer sealing lip 506 on the soft rubber frame 501 achieve a sealing fit between the inner end face of the dust box filter 500 and the assembly surface of the dust box's air outlet, and between the outer end face of the dust box filter 500 and the outer surface of the air outlet grille of the receiving cavity 200. This eliminates the traditional cumbersome process of adding sealing strips to the inside and outside of the dust box filter to meet the air flow path sealing requirements. The soft rubber frame 501, as a carrier, also includes the inner sealing lip 507 and outer sealing lip 506, which also have a certain degree of flexibility, as a sealing structure, resulting in a tighter contact, sealing and fit, a more satisfactory fit, a stronger sealing effect, and the airtight performance of the entire air flow path can be ensured, which plays a role in better protecting the functions of the cleaning device, such as dust collection and dust discharge, through negative pressure.

[0080] 11 and 12, the soft rubber frame further includes a stepped surface 503, which extends outward along the second end surface 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 to prevent the dust box filter from being installed too deeply in the dust box. During the assembly process, as shown in FIG. 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 locks onto the outer edge of the dust box, preventing the dust box filter from being installed too deeply in the dust box.

[0081] 11, the soft rubber frame further includes a magnetic device mounting hole 504, which is provided on a second end surface 50115 of the soft rubber frame 501 and is configured to be attached to a magnetic device to ensure that the dust box filter is mounted in place. 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 has a sufficient depth 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 mounted in place.

[0082] 11, the soft rubber frame further includes a second rib position 5041, which is disposed 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 breaking down. The second rib position 5041 may be a soft rubber material, which further encloses the magnetic device when pressed.

[0083] 11, the soft rubber frame further includes a grommet 505, which is provided at a position extending outward from the stepped surface 503 and configured to facilitate removal of the dust box filter. The shape and structure of the grommet 505 are not limited and may be semicircular, square, rectangular, etc.

[0084] In some embodiments, the soft rubber frame further includes a hollow structure 508, which is disposed in the first sidewall and / or the second sidewall of the frame and configured to reduce the overall weight of the frame, as shown in Figure 12. The hollow structure 508 may be a plurality of holes recessed inward, but the shape of the holes is not limited and may be round, square, rectangular, irregular, etc.

[0085] In the automatic cleaning device described in the above embodiments, the dust box filter is designed with a soft rubber frame, so that during the assembly process, it is directly pressed into the dust box opening and assembled, cooperating with structures such as the first protrusion, the inner sealing lip, and the outer sealing lip, thereby achieving the effect of tightly sealing the filter and the assembly surface during assembly. This avoids the traditional process of manually gluing the assembly parts with dotted adhesive after the filter is attached, simplifies the process, reduces the number of assembly parts, and at the same time reduces costs. It does not require adhesive bonding, is odorless, and is more environmentally friendly.

[0086] In some embodiments, the present embodiment further provides a dust box including the dust box filter described in the above embodiments, as shown in Figure 14. The structure of the dust box can be referred to in the above embodiments, and the description will be omitted here.

[0087] In some embodiments, an automatic cleaning device is further provided, which includes the dust box described in the above embodiments, and the structure of the automatic cleaning device can be referred to in the above embodiments, and the description thereof will be omitted here.

[0088] After the automatic cleaning device finishes suctioning, it enters the dust collection station to automatically collect dust. When the automatic cleaning device automatically collects dust, there is only one air flow path entering the automatic cleaning device, and the air flow path is obstructed by the structure of the equipment and is not smooth. This makes it difficult for the dust collection station to suck all the garbage in the dust box into its own garbage bag. In order to dispose of the garbage in the dust box as cleanly as possible, the power of the dust collection station fan needs to be increased, resulting in louder noise and more energy consumption.

[0089] In this regard, the embodiment of the present disclosure further provides an automatic cleaning device with a dust collection function. By improving the air flow path structure of the automatic cleaning device, airflow can more easily enter the dust box during the dust collection process of the automatic cleaning device, making it easier to clean the dust in the dust box. This embodiment explains some structural features compared to the above embodiment, and the same structures have similar technical effects, so some technical effects will be omitted here. Specifically, according to a specific embodiment of the present disclosure, the present disclosure provides an automatic cleaning device with a dust collection function, which includes a mobile platform 100 configured to automatically move on an operating surface. The mobile platform 100 mainly includes an upper casing, a lower casing, and a side casing that form the outer shape of the automatic cleaning device, as well as structures and accessories provided in the internal space of the casing. Specifically, the mobile platform 100 includes a storage cavity 200 and a drive wheel assembly 141. The storage cavity 200 is located substantially at the rear end of the mobile platform in the forward direction and is recessed inward. As described above, the drive wheel assembly 141 is provided on the lower casing of the mobile platform 100 and is used to provide forward power for the automatic cleaning device. The mobile platform 100 further includes a cleaning module 150, which includes a dust box 300 and a main brush module 153. The dust box 300 is detachably assembled to the receiving cavity 200. The structure of part of the dust box 300 can be referred to in the previous embodiment, and a description thereof will be omitted here. The dust box 300 further includes a first intake door 3013 and a second intake door 3014. The first intake door 3013 and the second intake door 3014 are located on the first side wall 3015 and the second side wall 3016 of the dust box, respectively.The first and second intake doors 3013 and 3014 are configured to provide intake airflows in two different directions during the dust collection process, contributing to the formation of air vortices within the dust box during dust collection, significantly reducing dust residue in the dust box, reducing dead airflow angles, and improving dust collection efficiency. The installation of two intake doors increases the intake speed and improves the formation of air vortices. The intake airflow sources include at least one of airflow I entering through the gap at the top of the mobile platform 100, airflow II entering through the gap in the main brush module 153, airflow III entering through the rear wall of the mobile platform, and airflow IV entering through the gap in the drive wheel assembly 141. The multiple sets of intake airflows increase the intake air volume and speed of the automatic cleaning device, improving the dust collection strength and efficiency of the dust collection station, further reducing dead airflow angles within the dust box, reducing dust residue, and improving the dust collection rate.

[0090] When the automatic cleaning device completes dust collection and returns to the dust collection station for dust collection, the dust collection station fan starts to suck in the dust inside the dust box. During the suction process, air flows through multiple channels and enters the dust box through the first air intake door 3013 and the second air intake door 3014, and is then sucked in together with the dust through the dust collection port by the dust collection station. In the dust collection state, the main cleaning brush of the automatic cleaning device moves in the reverse direction as the dust collection station fan starts, causing the automatic cleaning device to "spit out" dust. Airflow enters the internal cavity of the dust box from the outside of the automatic cleaning device through the gaps in the casing of the automatic cleaning device, forming a vortex in the internal cavity of the dust box, causing the dust in the internal cavity to rotate and rise up. The dust collection fan of the dust collection station starts, and communicates with the main brush, the first opening 3011 of the dust box, and the internal cavity of the dust box through a specific air flow path, and then uses suction force to suck the dust in the internal cavity of the dust box into a dust storage container or bag inside the dust collection station.

[0091] Here, the airflow entering the dust box mainly includes the airflow I entering through the gap at the top of the moving platform 100. Specifically, as shown in Figure 16, the airflow I entering through the gap at the top of the moving platform 100 includes the airflow entering through the gap between the protective cover 1212 and the top surface of the moving platform 100, and the airflow entering through the gap between the protective cover 1212 and the positioning device 1211. In the present disclosure, when the protective cover 1212 and the positioning device 1211 are assembled, airflow gaps are formed between the protective cover 1212 and the top surface of the mobile platform 100 and between the protective cover 1212 and the positioning device 1211 by support structures such as protrusions, and a negative pressure is formed in the dust box 300, which is in fluid communication with the fan of the dust collection station, due to the suction of the fan of the dust collection station, and the first air intake door 3013 and the second air intake door 3014 open toward the inside of the dust box, guiding the airflow outside the dust box to enter, and a negative pressure is also formed inside the mobile platform, guiding the gas outside the mobile platform to enter the inside of the equipment through the airflow gaps formed between the protective cover 1212 and the top surface of the mobile platform 100 and between the protective cover 1212 and the positioning device 1211. Compared with conventional sealing structures, the airflow gaps formed between the protective cover 1212 and the top surface of the moving platform 100 and between the protective cover 1212 and the positioning device 1211 increase the airflow path, ensuring sufficient airflow entering the dust box, further increasing the dust box's intake volume and intake speed, improving the dust collection strength and efficiency of the dust collection station, reducing dead spots in the airflow within the dust box, reducing dust residue, and improving the dust collection rate. More importantly, guiding the airflow to pass near the positioning device 1211 helps to dissipate excess heat generated during the operation of the positioning device, fulfilling a cooling role, improving the operating stability of the positioning device, and helping to extend the life of the electronic equipment. Furthermore, the airflow at the top is cleaner than other parts, making it safer and friendlier to the airflow path inside the equipment.

[0092] The airflow entering the dust box further includes airflow II, which enters through the gap in the main brush module 153. As shown in FIG. 17 , airflow II enters the casing through the assembly gap in the main brush module 153 at the bottom of the lower casing of the mobile platform 100. During assembly, a gap between the edge of the main brush module 153 and the edge of the drive wheel assembly 141 is formed by a protrusion, groove, or self-contained assembly gap. This creates a negative pressure within the mobile platform through the suction of the dust collection station fan, guiding air outside the mobile platform to naturally enter the interior of the device through the gap in the edge of the main brush module 153. Compared to conventional sealing structures, the gap in the edge of the main brush module 153 creates a larger airflow path, allowing sufficient airflow to enter the dust box, further improving the dust box's intake volume and intake speed. This improves the dust collection strength and efficiency of the dust collection station, reduces dead airflow angles within the dust box, reduces dust residue, and improves the dust collection rate. Furthermore, the distance that the airflow II takes to reach the two intake doors of the dust box is short and the duct is smooth, which further improves the replenishment speed of the airflow and ensures dust collection efficiency.

[0093] In some embodiments, an exhaust port 204 is provided on the rear wall of the mobile platform 100. As shown in Fig. 3a, the intake airflows further include an airflow III that enters through the exhaust port 204 in the dust collection state. As shown in Fig. 18a, in the dust collection state, a negative pressure is formed inside the mobile platform due to the suction of the dust collection station fan, and the exhaust port 204 guides the gas outside the mobile platform to enter the inside of the equipment through the exhaust port 204. Specifically, as shown in FIG. 18b, gas enters both sides of the fan bracket through the exhaust ports 204, then enters the outside of the side wall of the receiving cavity through the air notches 20115 in the sealing baffles 20114 on both sides of the fan bracket, and then enters the dust box through the air intake holes 20111 on the outside of the side wall of the receiving cavity, allowing a sufficient airflow to enter the dust box, further improving the air intake volume and speed of the dust box, improving the dust collection strength and efficiency of the dust collection station, further reducing dead spots in the air flow within the dust box, reducing dust residue and improving the dust collection rate. During the dust collection process, the rear side of the moving platform 100 is fully exposed to the environment, and the exhaust ports provided there function as air inlets, more smoothly replenishing the airflow. This reduces the airflow interference caused by external devices or the environment that come into contact with or fit into the cleaning device, and allows for safer and more efficient airflow replenishment. In some embodiments, air notches 20115 are provided at the bottom of the sealing baffle 20114 to reduce the impact of airflow on other components.

[0094] 18a, the airflow entering the dust box further includes airflow IV entering through the gaps in the drive wheel assembly 141, and the drive wheel is provided with an intake passage, and the airflow entering the casing through the gaps in the edge of the bottom of the drive wheel directly enters both sides of the storage cavity through the intake passages on the upper rear side of the drive wheel, and then directly enters the dust box through the air intake holes 20111. The path of airflow IV entering through the gaps in the drive wheel assembly 141 is shorter, making it easier to enter the airflow path of the dust box, and providing a larger amount of incoming airflow.

[0095] As shown in Figure 18a, the airflows of paths II and IV above split into two parts after entering the casing of the mobile platform 100: path I and path II airflows form the first part, and path IV airflow forms the second part. In the first part, path I airflow enters through the gap between the protective cover 1212 and the top surface of the mobile platform and the gap between the protective cover 1212 and the positioning device 1211 to directly reach the front of the receiving cavity 200. Path II airflow enters through the gap between the main brush and the lower housing, passes through the opening around the main brush's driving motor, and reaches the front wall of the receiving cavity 200. As shown in Figure 18a, due to the obstruction of the front wall 2010 of the receiving cavity 200, the airflow cannot directly reach the sides of the receiving cavity 200 and must instead reach the sides via the ducts 209 on both sides of the front wall. Specifically, as shown in FIG. 19, in some embodiments, the upper outer side of the front wall of the storage cavity 200 each includes a duct 209, and the air flow I entering from the top gap of the moving platform 100 and the air flow II entering from the gap of the main brush module 153 reach the multiple air intake holes 20111 on the side of the storage cavity 200 through the duct 209, enter the storage cavity 200 through the multiple air intake holes 20111, and then enter the dust box through the first air intake door 3013 and the second air intake door 3014. The second partial airflow IV reaches the plurality of air intake holes 20111 on the side of the storage cavity 200 from the air intake passage on the rear side above the direct drive wheels, enters the storage cavity 200 through the plurality of air intake holes 20111, and enters the dust box through the first air intake door 3013 and the second air intake door 3014.

[0096] As shown in Figure 18b, the rear side of the mobile platform includes a fan bracket 20116 and baffles 20114 on both sides of the fan bracket 20116. The baffles 20114 are connected to the top and bottom surfaces and side walls of the casing, and seal the fan bracket 20116 at the rear end of the mobile platform. The fan is connected to some exhaust ports 204 on the rear side wall of the mobile platform via an air exhaust pipe. These exhaust ports are called first exhaust ports. When the automatic cleaning device is cleaning, the fan exhausts air through some of the exhaust ports 204 connected to the air exhaust pipe, i.e., the first exhaust port, and when collecting dust, it takes in air through other exhaust ports 204 around the some of the exhaust ports 204 of the fan, i.e., the second exhaust port. That is, the second exhaust port is essentially an air intake port that does not directly communicate with the fan air exhaust pipe, and the baffle 20114 is provided with air notches 20115, so that the airflow of route III enters the interior of the moving platform casing through the second exhaust port 204, and then passes through the air notches 20115 in the baffles 20114 on both sides of the fan bracket to the plurality of air intake holes 20111 on the side of the receiving cavity 200, enters the receiving cavity 200 through the plurality of air intake holes 20111, and then enters the dust box through the first air intake door 3013 and the second air intake door 3014.

[0097] In an optional embodiment, the air outlet 204 further includes a third air outlet on the baffle 20114 opposite to the first or second air outlet, i.e., the air outlets 204 shown in Fig. 18b, whereby the airflow of path III enters through the third air outlet, and then directly reaches the plurality of air intake holes 20111 on the side of the accommodating cavity 200 from the third air outlet, enters the accommodating cavity 200 through the plurality of air intake holes 20111, and then enters the dust box through the first air intake door 3013 and the second air intake door 3014. This can improve air replenishment efficiency.

[0098] In some other embodiments, the third exhaust port may be a decorative hole that does not open or penetrate and serves only a decorative purpose, thereby avoiding unnecessary communication between the inside and outside of the automatic cleaning device and controlling the air in the automatic cleaning device.

[0099] 20 , the storage cavity 200 further includes a third side wall 2011 corresponding to the first side wall 3015 and a fourth side wall 2012 corresponding to the second side wall 3016. The third side wall 2011 and the fourth side wall 2012 each have a plurality of air intake holes 20111, and the plurality of air intake holes 20111 cover at least a portion of the first air intake door 3013 and the second air intake door 3014. The exteriors of the third side wall 2011 and the fourth side wall 2012 of the storage cavity 200 each include a plurality of spacers 20112, and the plurality of spacers 20112 form a plurality of air flow paths. In some embodiments, an apex of each spacer 20112 includes at least one notch 20113 communicating with the plurality of air flow paths. The multiple air channels formed by the multiple spacers 20112 ensure uniformity of the airflow entering the receiving cavity 200, preventing a portion of the airflow from reaching the outside of the air intake holes 20111, i.e., from entering the receiving cavity 200 but not immediately reaching the dust box, resulting in airflow loss. At the same time, the lost airflow forms convection with the airflow along path I-IV, affecting the efficiency of airflow entry into the dust box. After providing the multiple spacers 20112 to form a communication structure, the multiple air channels can reach the receiving cavity 200 more uniformly through the multiple air intake holes 20111, allowing air to enter the dust box more efficiently.

[0100] 21, the first intake door 3013 and the second intake door 3014 are disposed asymmetrically with respect to the first side wall 3015 and the second side wall 3016, respectively, to prevent the airflows entering from the two sides from directly canceling each other out and to allow the intake airflows entering from two different directions to intersect, which helps to more quickly form an air vortex within the dust box during dust collection, increases the swirling speed of the airflow entering the dust box, significantly reduces dust residue within the dust box, reduces dead spots in the airflow, and improves dust collection efficiency. In some embodiments, the second intake door 3014 is disposed near the lower edge of the second side wall 3016, and the lower edge of the second intake door 3014 is lower than the lower edge of the first intake door 3013, thereby further increasing the swirling speed of the airflow entering the dust box. In some embodiments, the second intake door 3014 is disposed adjacent to the rear wall of the dust box, and the first intake door 3013 is disposed adjacent to the front wall of the dust box, thereby further increasing the swirling velocity of the airflow entering the dust box. Here, in an assembled state, the front wall of the dust box is the side wall facing the forward direction of the automatic cleaning device of the dust box, and the rear wall of the dust box is the side wall facing the opposite side of the automatic cleaning device from the front wall. In some embodiments, the first intake door 3013 rotates substantially around a first rotation axis, and the second intake door 3014 rotates substantially around a second rotation axis, and the first rotation axis is substantially perpendicular to the second rotation axis, thereby further increasing the swirling velocity of the airflow entering the dust box. Here, the first and second rotating shafts are rotating shafts on which the first intake door 3013 and the second intake door 3014 are essentially provided, and may rotate around the position where the first and second rotating shafts are located via an elastic driving member.

[0101] The first intake door 3013 and the second intake door 3014 described in this embodiment are plate surfaces that cover the openings of the first side wall and the second side wall, and in the actual dust collection process, in order to open and close the first intake door 3013 and the second intake door 3014, it is necessary to add an elastic member connected to the first intake door 3013 and the second intake door 3014, and a fixing structure fixed to the outer surfaces of the first side wall and the second side wall, but this will not be explained here.

[0102] In some embodiments, the shapes of the first intake door 3013 and the second intake door 3014 may be at least one of a rectangle, a square, a circle, an oval, an elongated shape, or a combination thereof, but are not limited thereto. In some embodiments, the first intake door 3013 has a rectangular structure, with its long side extending along the vertical direction, and the second intake door 3014 has a rectangular structure, with its long side extending along the horizontal direction. By arranging the first intake door 3013 and the second intake door 3014 according to the above structure, the airflow forms vertical vortices and horizontal vortices, which lift up dust in all directions from multiple angles, efficiently improving the dust collection rate and further increasing the swirling speed of the airflow entering the dust box. Furthermore, the first air intake door 3013 and the second air intake door 3014 are designed to open inward. As shown in FIG. 21, when the first air intake door 3013 opens inward, the air vent is half-open, with the opening of the air vent facing the front wall of the dust box, and the incoming airflow is blown directly toward the front wall of the dust box. When the second air intake door 3014 opens inward, the air vent is also half-open, with the opening of the air vent facing the bottom of the dust box, and the incoming airflow is blown directly toward the bottom of the dust box. The airflows flowing in from the two dampers do not collide with each other, but form a swirling airflow. This accelerates the rotation of the dust inside the dust box and promotes the circulation of the dust to the dust outlet, allowing it to be sent out to the dust box.

[0103] In some embodiments, the dust box 300 further includes a first opening 3011 and a second opening 3012. The first opening 3011 is configured to function as a dust inlet during dust collection and a dust outlet during dust collection. The dust inlet during dust collection and the dust outlet during dust collection are provided as a single opening, reducing the number of openings and allowing existing openings to be efficiently shared, thereby reducing the possibility of air leakage. A filter is provided on the second opening 3012. The specific structure and installation method may be referred to the above embodiments and will not be described here. As shown in FIG. 22 , the first opening 3011 and the second opening 3012 are substantially located on the central axis of the automatic cleaning device in the front-to-rear direction. This design structure ensures that the air flow path is linear when the fan of the automatic cleaning device is used to collect dust, avoiding detouring airflow and improving airflow smoothness.

[0104] In some embodiments, the receiving cavity 200 includes a first cavity 201 and a second cavity 202, which are adjacently arranged in front and behind in the forward direction of the automatic cleaning device. A dust suction opening 203 is provided at the bottom of the front wall of the first cavity 201, and an air outlet 208 is provided at the rear wall of the connection between the first cavity 201 and the second cavity 202. The dust suction opening 203, the air outlet 208, the first opening 3011, and the second opening 3012 are all located substantially on the central axis of the automatic cleaning device in the front-to-rear direction. During dust suction or collection, the airflow does not pass through a zigzag duct or air passage, which reduces fan power and suction loss, maximizes fan effectiveness, saves energy, and reduces noise.

[0105] In some embodiments, the mobile platform 100 includes a positioning device 1211 located substantially on the central axis of the mobile platform 100 in the front-to-rear direction, and a protective cover 1212 disposed over the positioning device 1211. A fan is disposed in the space below the second cavity 202, and the positioning device 1211, protective cover 1212, fan, the main brush module 153, the dust suction port 203, the air outlet 208, the first opening 3011, and the second opening 3012 are all located substantially on the central axis of the automatic cleaning device in the front-to-rear direction. In the related art, when a single air inlet is used, the intake airflow is not symmetrical, the dust inlet is usually offset, which is unsightly, and the entire air flow path between the inlet and outlet is not linear, resulting in airflow obstruction and loss, and affecting the layout of other devices. After an air inlet is added, the air flow path structure is disposed on the central axis, and existing dust collection methods have the disadvantages of low dust collection efficiency and continuous dust collection. This overcomes the drawbacks of the existing technology, where the airflow path is offset and fan power and suction force are lost due to the zigzag duct, while at the same time significantly improving the aesthetic design and space for component placement. The port of the main brush module 153 is also located on the central axis, ensuring that the dust suction airflow path is not obstructed, reducing losses and improving efficiency.

[0106] According to a specific embodiment of the present disclosure, the present disclosure provides an automatic cleaning system including a dust collection station and any one of the automatic cleaning devices described above, wherein the dust collection station includes a dust collection port, and the dust collection port is connected to a port of the main brush module to collect dust.

[0107] FIG. 23 is a schematic structural diagram of a dust collection station provided according to some embodiments of the present disclosure, where the dust collection station 700 is configured to provide dirt collection for an automatic cleaning device.

[0108] 23 , the dust collection station 700 includes a dust collection station base 710 and a dust collection station body 720. The dust collection station body 720 is configured to collect dust in the dust box of the automatic cleaning device and is mounted on the dust collection station base 710. The dust collection station base 710 includes a dust collection port 711 that mates with a port of the main brush module of the automatic cleaning device, allowing dust in the dust box of the automatic cleaning device to enter the dust collection station body 720 through the dust collection port 711. In some embodiments, as shown in FIG. 22 , a seal gasket 714 is further provided around the dust collection port 711 to seal the dust collection port 711 against the port of the main brush module of the automatic cleaning device and prevent dust leakage.

[0109] 24 is a schematic diagram illustrating the state after the automatic cleaning device provided according to some embodiments of the present disclosure returns to the dust collection station. As shown in FIG. 24, after the moving platform 100 of the automatic cleaning device, such as a cleaning robot, returns to the dust collection station 700 after completing cleaning, the automatic cleaning device moves along the X direction to the dust collection station base 710, aligns the port of the main brush module of the automatic cleaning device with the dust collection port 711, and transfers the dirt in the dust box of the automatic cleaning device into the dirt bag of the dust collection station.

[0110] The present disclosure provides an automatic cleaning device and system, which has an automatic dust collection function, and by asymmetrically installing two dampers in the dust box of the automatic cleaning device, the airflow entering the dust box forms a convection current, forming a vortex cyclone inside the dust box, and smoothly sucking dust in the dust box into a dust collection station; further, by arranging the main brush module, dust suction port, air outlet, first opening, and second opening substantially on the central axis of the automatic cleaning device in the forward and backward directions, the speed of the airflow flowing through the dust box during dust collection can be further increased, improving dust collection efficiency and simultaneously making it possible to easily suck dust in the dust box into the dust collection station during dust collection.

[0111] Finally, please note that each embodiment in this specification will be described progressively, with each embodiment focusing on differences from other embodiments, and that identical or similar parts between each embodiment may be referenced to each other.
