[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, but obviously, the described embodiments are only some embodiments of the present disclosure, 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 specific embodiments, and are not intended to limit the present disclosure.

[0024] It should be noted that the term "and / or" as used herein is merely an explanation of 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 addition, in the embodiments of the present disclosure, terms such as first, second, and third may be used for explanation, but it should be understood that they should not be limited to these terms. These terms are used only for distinction. For example, the first may be called the second, and similarly, the second may be called the 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 that includes a set of elements not only includes those elements, but also includes other elements explicitly listed or inherent in those products or devices. Unless further limited, an element defined with the term "comprises" 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 FIG. 1 and FIG. 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 across 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 a 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 an inner surface of a pipe, and the inner pipe surface is the manipulation surface. Purely for purposes of illustration, a mopping robot is used as an example in this disclosure.

[0030] In some embodiments, the mobile platform 100 may be an autonomous mobile platform or a non-autonomous mobile platform. The autonomous mobile platform means that the mobile platform 100 itself can automatically and adaptively make operational decisions in response to unexpected environmental inputs, while the non-autonomous mobile platform itself cannot adaptively make operational decisions in response to unexpected environmental inputs, but can operate according to a predetermined procedure or a certain logic. Correspondingly, when the mobile platform 100 is an autonomous mobile platform, the target direction may be determined autonomously by an automatic cleaning device, and when the mobile platform 100 is a non-autonomous mobile platform, the target direction may be set by a system or manually. When the mobile platform 100 is an autonomous mobile platform, the mobile platform 100 is composed of a forward-facing part 111 and a backward-facing part 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 at the bottom of the mobile platform, and other 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 moving 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 on the floor surface by various combinations of movement about three mutually perpendicular axes defined by the mobile platform 100: the lateral axis Y, the front-rear axis X, and the central vertical axis Z. The forward drive direction along the front-rear axis X is designated as "forward", and the rear drive direction along the front-rear axis X is designated as "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 about the Y axis. If the forward facing part of the automatic cleaning device is tilted upward and the rear facing part is tilted downward, it is called "pitch up", and if the forward facing part of the automatic cleaning device is tilted downward and the rear facing part is tilted upward, it is called "pitch down". In addition, the automatic cleaning device can rotate about the Z axis. If the automatic cleaning device is tilted to the right of the X axis at the front of the automatic cleaning device, it is called "turn right", and if the automatic cleaning device is tilted to the left of the X axis, it is called "turn left".

[0033] 2, cliff sensors 123 are provided at the bottom of the moving platform 100, in front of and behind the drive wheel assembly 141. The cliff sensors can prevent the automatic cleaning device from falling when retreating, and prevent damage to the automatic cleaning device. The above "front" refers to the same side as the traveling direction of the automatic cleaning device, and the above "rear" refers to the opposite side to the traveling direction of the automatic cleaning device.

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

[0035] Each assembly in the sensing system 120 may operate independently or in concert to achieve more precise purpose and function. 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 cameras, laser ranging devices, etc. to make more precise determinations.

[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 bumper 122 is provided on the forward-facing portion 111 of the moving 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 bumper 122 detects one or more events (or objects) in the travel path of the automatic cleaning device via a sensor system, e.g., an infrared sensor. The automatic cleaning device may control the drive wheel assembly 141 in response to the event (or object), e.g., through an obstacle, wall, detected by the bumper 122, so that the automatic cleaning device moves away from the obstacle, for example.

[0038] The control system 130 is provided on a circuit board in the mobile platform 100 and includes a central processing unit, an application processor, etc., which communicates with a non-transitory memory such as a hard disk, a flash memory, a random access memory, etc., and the application processor receives the environmental information sensed by the multiple sensors from the sensing system 120, the obstacle information fed back from the positioning device, etc., and uses a positioning algorithm, such as SLAM, to draw an instant map of the environment in which the automatic cleaning device is installed, and autonomously determines a travel path based on the environmental information and the environmental map, and then controls the operation of the drive system 140, such as forward, backward, and / or steering, 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 the distance information and speed information fed back from the buffer 122, cliff sensor 123, and sensing devices such as ultrasonic sensor, infrared sensor, magnetometer, accelerometer, gyroscope, odometer, etc. to comprehensively determine the current working state of the vacuum cleaner, such as over the threshold, climbing up the carpet, located on the cliff, stuck above or below, the dust box is full, lifted, etc., and gives specific next operation strategies according to different situations, so that the work of the automatic cleaning device can better meet the owner's requirements and give a better user experience. In addition, the control system can plan the most efficient and reasonable cleaning path and cleaning method according to the instant map information drawn by SLAM, which can greatly improve the cleaning efficiency of the automatic cleaning device.

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

[0041] In order for the automatic cleaning device to move more stably on the floor surface or 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 driving wheel, and its structural form may be a universal wheel. The steering assembly 142 may be located in front of the driving wheel assembly 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 charging 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 the charging pile for charging via a charging electrode provided on the side or bottom of the main body.

[0043] The human-machine interactive system 170 includes keys on a host panel, which are available for 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, a map of the environment in which the device is installed and the location of the device can be displayed to the user in the mobile phone client, which can provide the user with richer and more convenient function items.

[0044] As shown in FIG. 2, the 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 has some interference with the floor surface, sweeps up the dust on the floor surface to the front of the dust suction port between the roller brush and the dust box, and sucks it into the dust box through the suction gas generated by the fan that passes through the dust box. The dust removal capacity of the vacuum cleaner is indicated by the dust pickup efficiency DPU. The cleaning efficiency DPU is affected by the structure and material of the roller brush, by the wind power utilization rate of the duct consisting of the dust suction port, the dust box, the fan, the air outlet, and their connecting members, and by the type and power of the fan, which is a complex system design issue. Compared with ordinary plug-in dust collectors, the improvement of the dust removal capacity is of great significance for automatic cleaning devices with energy limitations. The improvement of the dust removal capacity directly and effectively reduces the required energy, that is, a machine that can clean 80 square meters of floors on one charge can be evolved to clean more than 180 square meters on one charge. In addition, by reducing the number of charging times, the battery life is also greatly extended, and users can replace the batteries less frequently. More intuitively and importantly, the improvement of the dust removal ability is the most obvious and important user experience, and the user can directly conclude whether the machine cleans cleanly or wipes cleanly. The dry cleaning module may further include a side brush 152 having a rotating shaft, which is at an angle to the floor surface and moves the 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 part 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 in the water tank flows along a water circuit to the cleaning head, and the cleaning head cleans at least a part of the operating surface under the driving of the driving unit.

[0047] In the existing automatic cleaning device, the casing layout frame structure is complicated, there are many parts, many assembly steps, and the process is cumbersome. The cost is high because the top flap and flip mechanism of the automatic cleaning device are added, and the top casing decorative parts and the like are designed on the top flap. Although the top casing decorative parts and the top flap can fulfill the functions of covering up ugly things and protecting the internal parts, the structure of the entire machine is complicated, the cost is high, and the design space of the dust box under the top flap is affected.

[0048] In this respect, the embodiments of the present disclosure provide an automatic cleaning device without a flip cover. The design space of the dust box and its storage cavity can be enlarged while simplifying unnecessary components of the automatic cleaning device. The same structure provides the same technical effects, and some technical effects are not repeated in this specification. Specifically, the present disclosure provides an automatic cleaning device, which includes a moving platform 100 configured to automatically move an operation surface, and a dry cleaning module 151, as shown in FIG. 3, in which the moving platform 100 includes a storage cavity 200, and in some embodiments, the storage cavity 200 is provided 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, and the dry cleaning module 151 includes a dust box 300, and the dust box 300 is detachably 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 a larger part of the volume and weight of the entire dust box is located closer to the center of the automatic cleaning device, so that the dust box is more stably arranged in the accommodating cavity 200, making the center of gravity of the entire cleaning device more stable, and making it more stable during the processes of moving forward, turning, crossing obstacles, etc., and not easily falling over. At the same time, the dust box accommodating part and the dust box top cover are integrated into one structure, and the dust box top cover functions as a part of the top surface of the moving platform and is flush with the other parts of the top surface of the moving platform. This eliminates the flip cover structure of the conventional cleaning device, and allows the dust suction port located approximately in the center of the bottom of the cleaning device to be easily and directly aligned with the dust box, allowing dust to enter the dust box directly from the dust suction port, reducing the process of dust entering the inside of the device, and avoiding dust contamination inside the device.The depth of the first cavity 201 is deeper than that of the second cavity 202, so that the dust box and the dust box top cover can be accommodated in a separate structure, and the integrated design of the dust box top cover is facilitated. 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 at the rear wall of the connection point between the first cavity 201 and the second cavity 202. The air outlet 208 has a grill structure. A fan is accommodated in the space below the second cavity 202, and the fan is supported by a fan bracket. In some embodiments, the air outlet 208 forms a part of the fan bracket, and an exhaust port 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 airflow is filtered by the dust box filter and then exhausted through the exhaust port 204.

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

[0050] The roller brush, which interferes with the floor surface to a certain extent, sweeps up 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. The dust is then sucked into the dust box 300 by the suction airflow passing through the dust box 300 generated by the fan, 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 wash the filter. Here, the front side refers to the side along the forward 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 opposite side to the forward direction of the automatic cleaning device in the X direction.

[0052] In some embodiments, the top cover 302 includes a first portion 3021 covering the receiving portion 301 and a second portion 3022 protruding 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 portion of the first cavity and the structure of the second cavity. This allows the dust box 300 to be stably installed in the accommodating cavity 200, and prevents the dust box from shaking due to vibration during the operation of the automatic cleaning device; at the same time, the top cover of the dust box can exactly cover the position of the accommodating part and the fan, the upper surface of the top cover of the dust box is approximately level with the upper surface of the moving platform, the flatness of the outer surface of the automatic cleaning device is ensured, the overall appearance is better coordinated, more space options are provided for the design of each component, including the accommodating part, on the underside of the top cover, which is convenient for arranging the positions of different components, the volume options of the dust box are improved, specific sizes can be set as needed, and the molding costs can be reduced without affecting the overall opening size of the accommodating cavity.

[0053] In some embodiments, the first portion 3021 of the top cover 302 includes an edge 30211 that protrudes from the edge contour of the storage portion and extends outward. 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 edge 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 a step 205 that extends around the top edge of the storage cavity, and can fully receive the edge of the top cover 302, and the top cover 302 is received in the storage cavity 200 in a substantially gapless manner, which can prevent foreign objects from directly falling into the gap at the edge of the dust box and getting caught in the dust box, and at the same time ensure 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 part 3022 of the top cover 302 is provided below the second part 3022 of the top cover 302. Optionally, the support structure 3023 is integrally molded with at least a part of the receiving part 301, so as to enhance the support force of the support structure 3023 on the second part 3022 of the top cover 302 and effectively avoid damage thereto. The support structure 3023 includes, 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 part 3022 of the top cover 302.

[0055] In some embodiments, a groove 2021 is provided on the bottom surface of the second cavity 202. The groove 2021 substantially matches the contour of the support structure 3023, such 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 top 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 direction 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 ellipse, a triangle, a square, a pentagon, a hexagon, a heptagon, and an octagon, or a combination thereof. By symmetrically arranging the top cover, the appearance of the device can be maintained even if it is not covered by an outer cover, and the dust box can be easily attached and detached.

[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 includes 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 upper surface of the dust box top cover is substantially flush with the upper 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 provided with a pop-up dust box, a non-pop-up dust box, a pop-up dust box top flap and a flip mechanism. When attaching or detaching the dust box, the top flap needs to be opened and the dust box needs to be pressed to pop up. In this embodiment, a complex dust box pop-up mechanism needs to be provided, and the dust box pop-up mechanism includes multiple parts such as a spring, and the elasticity of the spring is reduced by repeated use, so that the dust box cannot be popped up smoothly. In addition, the dust box may not be able to pop up normally due to many other parts, which has a negative impact on use. Non-pop-up dust boxes mostly adopt a locking structure with a complex structure, in which the spring assembly is easily damaged due to aging, and the pressing member does not fit well with the fingers when operating, resulting in a poor overall user experience.

[0060] In this respect, the embodiment of the present disclosure provides an automatic cleaning device without a flip cover, which can simplify unnecessary elements of the automatic cleaning device while facilitating smooth removal of the dust box. In this embodiment, some structural features are briefly described compared with the above embodiment, but the same structure has the same technical effect, and some technical effects are not repeated in this specification. 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 substantially located on the central axis of the top cover. Here, the first locking mechanism 610 includes at least a first grommet recess portion 603 and a first locking member 601. The first locking member 601 is located in the first grommet recess 603, and the first locking member 601 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 part of the top cover, and the first grommet recess 603 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 to provide 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 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 the end of the first elastic arm 6011 that extends upward. 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 in a substantially "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, and 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 be in an arc shape, that is, the projection on the horizontal plane is in an arc shape, and the grommet surface facilitates the reception of manual operations and the finger shape conforms to ergonomic relationships. 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. To facilitate the insertion of the first locking member 701, the width of the sheet structure decreases from the root portion to the free end. The first elastic arm 6011 can be formed from a general elastic material as a whole, such as plastic or an organic elastic material.

[0062] In some embodiments, as shown in FIG. 8, which is an enlarged schematic view of the first locking member at A in FIG. 3a, a first locking member 701 is provided at a position substantially corresponding to the first locking member 601 on the inner wall of the receiving cavity 200, 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 end of the sheet structure is inserted into the through holes and locked.

[0063] In some embodiments, a first recess 206 is provided at a position substantially corresponding to the first grommet recess 603 on the inner wall of the receiving cavity, and the pair of through holes are provided on both sides of the first recess 206. When the first locking member 601 enters the through hole, locking is achieved, and 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, unlocking is achieved. The cooperation between the first recess 206 and the first grommet recess 603 makes the access operation by 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, for example an arc-shaped or square-shaped notch, on the inside along approximately the midline position of the top cover second part 3022, which is easy for fingers to reach for snap operation. The second locking member 602 is located below the second grommet recess 605, and the second grommet recess 605 provides enough space for fingers to control the second locking member 602, and the second locking member 602 elastically moves 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 the second elastic arm 6021 includes two symmetrical parts, and each second elastic arm 6021 first extends along the opening direction of the second grommet recess 605, then extends along the direction of the edge of the top cover, and then extends along the direction of the edge 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 to the outside, as shown in FIG. 9a, and in this embodiment, it is also the rear of the dust box top cover, and the two parts of the second elastic arm 6021 are symmetrically connected to each other in a substantially two "box" shaped structure. The second grommet part 6022 is connected to the two parts of the second elastic arm 6021 that are symmetrically arranged. Specifically, the second grommet portion 6022 is provided 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 in Fig. 9bC, 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, and the grommet surface extends to a position where it is substantially flush with the top cover. The grommet surface may have an arc-shaped structure, and the grommet surface facilitates receiving manual operation and is convenient for fingers to apply force.Alternatively, the second grommet portion 6022 is integrally formed with the symmetrically arranged second elastic arm 6021, and the second buckle portion 6023 is provided on a lateral extension 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 alternative embodiment, each of the second buckle portions 6023 has a groove extending inward from an end of the second buckle portion 6023, which can prevent the second buckle portion from being too deformed after the entire second buckle portion is molded and cooled, making it difficult to snap. 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 to and fixed on an end surface of a support structure. The second grommet portion 6022 is exposed from the second grommet recess portion 605 in the X direction, and when unlocking, a finger reaches the second grommet recess portion 605 and presses the second grommet portion 6022, applying a 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 to achieve unlocking. The second elastic arm 6021 as a whole is generally formed of 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 B of Fig. 3b, a second locking member 702 is provided at a position on the inner wall of the receiving cavity 200 that substantially corresponds to the second locking member 602, and the second locking member cooperates with the second locking member to be locked. The second locking member is a pair of protrusions, and a second buckle portion 6023 enters the bottom of the second locking member 702 to achieve locking. The protrusions may be flat, cylindrical, rectangular, etc., 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 at a position on the underside of the second cavity 202 that substantially corresponds to the second grommet recess 605, and the pair of protrusions are provided at the same height on the rear wall of the second cavity 202 and located above the second recess 207. The second recess 207 is configured to be accommodated avoiding the second locking member 602 when the dust box 300 is placed in the receiving cavity 200, and the entire dust box can be well placed in a predetermined position in the receiving 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 acting force.

[0068] In the dust box lock structure described in the above embodiment, the lock structure is symmetrically arranged in the front and rear direction of the dust box top cover, and the lock can be released by applying force to the two elastic structures in the front and rear of the dust box with one hand, which avoids the dust box on one side from being tilted due to the dust box being popped up when one side is unlocked. At the same time, the elastic structure is simple, and the elastic unlock can be achieved by forming the elastic arm with an elastic material, so that the damage of the complex unlocking device such as a spring can be avoided.

[0069] In some embodiments, as shown in FIG. 4, the second locking mechanism 620 includes at least one first magnetic attraction module 604, and the first magnetic attraction module 604 is disposed between the second portion of the top cover and the support structure. As shown in FIG. 3a, 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. In the application process, the first locking member 601 corresponding to the dust box can be retracted by pressing the first locking member 601 and the second grommet recessed portion 605 with the hand, and when the dust box is put into 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, and the first magnetic attraction module 604 is attracted to the second magnetic attraction module 606, thereby achieving the locking of the dust box. The locking structure is simple and easy to operate, and is convenient for realizing the locking of the dust box.

[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 the existing automatic cleaning device needs to be equipped with a replaceable dust box filter, and the conventional filter generally uses a hard frame made of plastic or metal, a cascading filter medium is put into the frame, and a dot adhesive is used to connect and seal the frame and the periphery of the filter medium, and then a sealing strip is attached on the frame to seal the gap between the filter and the dust box. Therefore, the conventional dust box filter part has a complicated structure, the filter installation process is complicated, there is a waste of labor and cost, and the sealing adhesive is not economical and 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 operation surface, the moving platform including a receiving cavity; and a cleaning module including a dust box. The dust box is detachably mounted in the receiving 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 has some simplified structural features compared with the above-mentioned embodiments, and the same structure has the same technical effects, and some technical effects are omitted here. Specifically, as shown in FIG. 11 and FIG. 12, the 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 the assembly process, and a filter material 502 sleeved in the soft rubber frame 501. Here, the soft rubber frame 501 is non-detachably connected to the filter material 502. The specific process of 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 a rubber sleeve can be sleeved on the sleeved frame combination to integrally form a plurality of desired sealing protrusions. Alternatively, a two-shot injection molding process can be used to first inject the hard rubber frame body, and then sleeve the filter material on the frame body, and then inject the soft rubber to form the inner and outer sealing protrusions.

[0073] The soft rubber frame may be rectangular, square, elliptical, circular, polygonal, etc., and the structure is not limited thereto. In some embodiments, as shown in Fig. 11 and Fig. 12, the soft rubber frame is rectangular, and the soft rubber frame of the rectangular structure includes two first side walls 50111 and two second side walls 50113 arranged opposite each other. 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 around the rectangular structural frame, and a filter medium is sleeved in the rectangular structural frame.

[0074] In some embodiments, the first protrusion 5011 and the second protrusion 5015 are continuous protrusion structures, 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 soft rubber structures, when the dust box filter is assembled into the dust box, the first protrusion 5011 and the second protrusion 5015 are pressed 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 fully contacted and sealed with the inner wall extending along a substantially horizontal direction, which replaces the traditional step of sealing through 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 is 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 from the dust box. Specifically, the reversible buckle structure is an arc-shaped structure, and the arc-shaped structure is inclined toward the opposite side to the assembly direction of the dust box filter. The reversible buckle structure makes it convenient for the dust box filter to extend into the assembly opening of the dust box with friction, 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 be a distributed multi-protrusion structure. In one embodiment, the third protrusions 5012 are distributed on the outer circumferential surface of the two second side walls 50113 of the frame structure, and 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 long structure, and extends into the recess of the dust box side wall to function as a fastener and prevent the dust box filter from falling off. During the assembly of the dust box filter, the slightly long third protrusion 5012 is first inserted into the recess of 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, and when the dust box filter is assembled to the dust box, the third protrusions 5012 on the side are interlocked with the elastic structure 5013 of the side wall of the dust box by interference fit, preventing the dust box filter from falling off. Here, the elastic structure 5013 is substantially an S-structure, including an inner recess for accommodating the third protrusion 5012 and an outer protrusion interlocked with the third protrusion 5012. The outer protrusion moves elastically under the action of an external force to interlock with the third protrusion 5012. Figure 15 shows the installation structure of the dust box filter when viewed 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 the dust box filter from being installed too deeply or too shallowly in the dust box, resulting in assembly failure. During the process of installing the dust box filter in the dust box, after it 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, which can prevent the filter from further stretching inward and prevent 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 that the dust box filter can be prevented from being installed too shallowly in the dust box.

[0077] In some embodiments, as shown in Figures 13a and 13b, the soft rubber frame further includes a protrusion 509 for preventing mis-installation, 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 in the wrong direction. A recess is provided at a position corresponding to the protrusion 509 for preventing mis-installation of the dust box, and when the dust box filter is installed normally, the protrusion 509 for preventing mis-installation enters the recess to assemble the dust box filter normally, and when the dust box filter is installed in the wrong direction, the protrusion 509 for preventing mis-installation cannot assemble the dust box filter because there is no recess on the other side of the dust box, so that the dust box filter is installed in the wrong direction and prevents mis-installation.

[0078] In some embodiments, as shown in Figures 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 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 that 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 of the connection between the first cavity 201 and the second cavity 202, a fan is accommodated in the space below the second cavity 202, and an exhaust port 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 airflow is filtered by the dust box filter and then exhausted through the exhaust port 204. Here, the air outlet 208 is provided with a grill structure.

[0079] As shown in Figures 11 and 12, the soft rubber frame further includes a sealing inner lip 507. The sealing inner lip 507 is provided on the first end surface 50116 of the soft rubber frame 501 to surround the filter medium 502, and is configured to realize a sealing 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 close to the inner wall of the dust box in the second opening, has a substantially planar structure, and is abutted against the first end surface 50116 of the soft rubber frame 501 to be assembled to the soft rubber frame. The sealing outer lip 506 is provided on the 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 and the edge of the air outlet 208 of the receiving cavity 200. The sealing inner lip 507 and the sealing outer lip 506 are higher than the first end surface 50116 or the second end surface 50115 where they are located, and after being assembled in a predetermined position, 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 a soft material, it seals the dust box filter with the assembly surface of the dust box under the action of pressing force. When the dust box is assembled into 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 with 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 sealing inner lip 507 and the sealing outer lip 506 provided on the soft rubber frame 501 realize the sealing engagement 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 grill outer surface of the air outlet of the receiving cavity 200, thereby eliminating the traditional cumbersome step of adding sealing strips on 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 sealing inner lip 507 and the sealing outer lip 506, which have a certain degree of flexibility as a sealing structure, so that the contact, sealing and engagement are tighter, fit more fully, and the sealing effect is stronger, which can ensure the airtight performance of the entire air flow path, and plays a role of better protecting the functions of the cleaning device such as dust suction and dust discharge by negative pressure.

[0080] In some embodiments, as shown in Figures 11 and 12, the soft rubber frame further includes a step surface 503, which extends outward along the second end surface 50115 of the soft rubber frame 501, and the step surface 503 and the side wall of the soft rubber frame 501 form a step structure, which is configured to prevent the dust box filter from being installed 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 step surface 503 abuts against the outer edge of the dust box assembly and is locked with the outer edge of the dust box, thereby preventing the dust box filter from being installed too deeply in the dust box.

[0081] In some embodiments, as shown in Fig. 11, the soft rubber frame further includes a magnetic device mounting hole 504, which is provided on the 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 a predetermined position. The magnetic device can 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 so that the magnetic device can 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 a predetermined position.

[0082] In some embodiments, as shown in Figure 11, the soft rubber frame further includes a second rib location 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 location 5041 tightly cradles the outer end of the magnetic device outside the magnetic device mounting hole 504, thereby preventing the magnetic device from rusting and becoming damaged. The second rib location 5041 may be a soft rubber material, which further cradles the magnetic device when pressed.

[0083] In some embodiments, as shown in Figure 11, the soft rubber frame further includes a grommet 505, which is disposed at a position extending outward from the step 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, disposed in a first sidewall and / or a second sidewall of the frame, configured to reduce the overall weight of the frame, as shown in Figure 12. The hollow structure 508 may be a plurality of inwardly recessed pin holes, although the shape of the pin holes is not limited and may be circular, 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 and assembled into the dust box opening, and at the same time cooperates with the first protrusion, the sealing inner lip, the sealing outer lip and other structures to achieve the effect of tightly sealing the filter and the assembly surface during assembly. After being attached to the filter, the traditional process of manually gluing the assembly parts with dot adhesive can be avoided, the process is simplified, the number of assembly parts is reduced, and at the same time, costs are reduced, and there is no need for adhesive bonding, which is odorless and more environmentally friendly.

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

[0087] In some embodiments, an automatic cleaning device is further provided, which includes a dust box as described in the above embodiments, and the structure of the automatic cleaning device can be referred to in the above embodiments, and the description 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 blocked by the structure of the equipment and is not smooth, so it is difficult for the dust collection station to suck all the garbage in the dust box into the garbage bag of the dust collection station. 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 dust collection function, and improves the air flow path structure of the automatic cleaning device, so that the airflow can more easily enter the dust box during the dust collection process of the automatic cleaning device, and the garbage in the dust box can be more easily cleaned. This embodiment describes some structural features compared with the above embodiment, and the same structure has the same technical effect, and some technical effects are omitted here. Specifically, according to a specific embodiment of the present disclosure, the present disclosure provides an automatic cleaning device with dust collection function, which includes a moving platform 100, and the moving platform 100 is configured to automatically move on an operation surface, and the moving platform 100 mainly includes an upper casing, a lower casing, a side casing, which form the outer shape of the automatic cleaning device, and structures and accessories provided in the inner space of the casing. Specifically, the moving platform 100 includes a receiving cavity 200 and a driving wheel assembly 141. The receiving cavity 200 is substantially provided at the rear half position in the forward direction of the moving platform, and the receiving cavity 200 is formed by recessing inward. As mentioned above, the driving wheel assembly 141 is provided on the lower casing of the moving platform 100 and is used to provide forward power for the automatic cleaning device. The moving 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, and the structure of part of the dust box 300 can be referred to the above embodiment, and the description 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 respectively located on the first side wall 3015 of the dust box and the second side wall 3016 of the dust box.The first intake door 3013 and the second intake door 3014 are configured to provide intake airflows in two different directions during the dust collection process, which contribute to the formation of an airflow vortex in the dust box during dust collection, greatly reducing the amount of dust remaining in the dust box, reducing the dead angle of the airflow, and improving the dust collection efficiency. The installation of two intake doors increases the intake speed and improves the formation efficiency of the airflow vortex. Here, the sources of the intake airflow include at least one of the airflow I entering through the gap at the top end of the moving platform 100, the airflow II entering through the gap of the main brush module 153, the airflow III entering through the rear side wall of the moving platform, and the airflow IV entering through the gap of the driving wheel assembly 141. By setting multiple sets of intake airflows, the intake amount and intake speed of the automatic cleaning device are increased, the dust collection strength and dust collection efficiency of the dust collection station are improved, and the dead angle of the airflow in the dust box is further reduced, the dust residue is reduced, and the dust collection rate is improved.

[0090] When the automatic cleaning device completes the dust suction and returns to the dust collection station to perform dust collection, the dust collection station fan starts to suck in the dust in the dust box. During the suction process, the airflow passes through multiple flow paths and enters the dust box through the first air intake door 3013 and the second air intake door 3014, and is then sucked in from the dust collection port by the dust collection station together with the dust. In the dust collection state, the cleaning main brush of the automatic cleaning device moves in the reverse direction with the start of the dust collection station fan, the automatic cleaning device enters the state of "spitting out" dust, the airflow enters the internal cavity of the dust box from the outside of the automatic cleaning device through the gap in the casing of the automatic cleaning device, the airflow forms a vortex in the internal cavity of the dust box, the dust in the internal cavity of the dust box rotates and soars 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 sucks the dust in the internal cavity of the dust box into a dust storage container or bag inside the dust collection station by suction force.

[0091] Here, the airflow entering the dust box mainly includes the airflow I entering through the gap at the top end of the moving platform 100. As shown in Fig. 16, specifically, the airflow I entering through the gap at the top end 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 moving 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 that 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 intake door 3013 and the second intake door 3014 open toward the inside of the dust box to guide the airflow outside the dust box to enter, and a negative pressure is also formed inside the moving platform, and the gas outside the moving platform is guided to enter the inside of the equipment through 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. Compared with the conventional sealing structure, 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, ensure sufficient airflow enters the dust box, further increase the intake volume and intake speed of the dust box, improve the dust collection strength and dust collection efficiency of the dust collection station, reduce the airflow blind spot in the dust box, reduce dust residue, and improve the dust collection rate. More importantly, the airflow is guided to pass near the positioning device 1211, which helps to take away excess heat generated during the operation of the positioning device, plays a cooling role, improves the work stability of the positioning device, and helps to extend the life of the electronic equipment. In addition, the airflow at the top is cleaner than other parts, and is safer and more friendly to the airflow path inside the equipment.

[0092] The airflow entering the dust box further includes airflow II entering through the gap of the main brush module 153. As shown in FIG. 17, airflow II enters the casing from the assembly gap of the main brush module 153 at the bottom surface of the lower casing of the moving platform 100, whereby a gap at the edge of the main brush module 153 and a gap at the edge of the driving wheel assembly 141 are formed by a protrusion, groove, or self-contained assembly gap during assembly of the device, and a negative pressure is formed in the moving platform by the suction of the dust collection station fan, which guides the gas outside the moving platform to naturally enter the inside of the device through the gap at the edge of the main brush module 153. Compared with the conventional sealing structure, the gap at the edge of the main brush module 153 increases the air flow path, allowing sufficient airflow to enter the dust box, further improving the intake volume and intake speed of the dust box. This improves the dust collection strength and dust collection efficiency of the dust collection station, reduces the dead angle of the airflow in the dust box, reduces dust residue, and improves the dust collection rate. In addition, 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 can further improve the replenishment speed of the airflow and ensure the dust collection efficiency.

[0093] In some embodiments, an exhaust port 204 is provided on the rear wall of the moving platform 100. As shown in Fig. 3a, here, the multiple intake airflows further include an airflow III entering from 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 moving platform due to the suction of the dust collection station fan, and the exhaust port 204 guides the gas outside the moving 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 accommodating cavity through the air notches 20115 of 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 accommodating cavity, so that sufficient airflow can enter the dust box, further improving the air intake volume and air intake speed of the dust box, improving the dust collection strength and dust collection efficiency of the dust collection station, further reducing the airflow blind spot in the dust box, reducing garbage 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 therein can function as airflow inlets to more smoothly replenish the airflow, and reduce the interference of external equipment or the environment that contacts or fits with the cleaning device with the airflow, so as to more safely and efficiently replenish the airflow. In some embodiments, air cutouts 20115 are provided at the bottom of the sealing baffle 20114 to reduce the impact of airflow on other components.

[0094] 18a, the airflow of the inlet dust box further includes airflow IV entering through the gap of the drive wheel assembly 141, and the drive wheel is provided with an intake passage, and the airflow entering the casing through the edge gap at the bottom of the drive wheel directly enters both sides of the accommodation cavity through the intake passage at the rear side of the upper part of the drive wheel, and then directly enters the dust box through the intake hole 20111. The path of the airflow IV entering through the gap of the drive wheel assembly 141 is shorter, and it is easier to enter the airflow path of the dust box, and more inlet airflow can be provided.

[0095] As shown in Fig. 18a, the airflow of the above-mentioned paths II and IV enters the casing of the moving platform 100 and then splits into two parts, the I and II path airflows form the first part, and the IV path airflow forms the second part. Here, in the first part airflow, the I path airflow enters through the gap between the protective cover 1212 and the top surface of the moving platform and the gap between the protective cover 1212 and the positioning device 1211 to directly reach the front of the receiving cavity 200, and the II path airflow enters through the gap between the main brush and the lower housing, and then passes through the opening around the driving motor of the main brush to reach the front wall of the receiving cavity. As shown in Fig. 18a, due to the blocking of the front wall 2010 of the receiving cavity 200, the airflow cannot directly reach the side of the receiving cavity 200, but reaches the side of the receiving cavity 200 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 airflow I entering from the top gap of the moving platform 100 and the airflow 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 enter the dust box through the first air intake door 3013 and the second air intake door 3014. The second partial air flow IV reaches the multiple 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 multiple 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 Fig. 18b, the rear side of the moving platform includes a fan bracket 20116 and baffles 20114 on both sides of the fan bracket 20116. The baffles 20114 are connected to the upper and lower surfaces and side walls of the casing, and the baffles 20114 seal the fan bracket 20116 at the rear end of the moving platform. The fan is connected to some exhaust ports 204 on the rear side wall of the moving platform through an air exhaust pipe. These exhaust ports are called first exhaust ports, and when the automatic cleaning device is cleaning, the fan exhausts air through some exhaust ports 204 that communicate with 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 above-mentioned some exhaust ports 204 of the fan, i.e., the second exhaust port. That is, the second exhaust port is actually an intake port that does not directly communicate with the fan air exhaust pipe, and an air notch 20115 is provided in the baffle 20114, so that the III-path airflow enters the inside of the moving platform casing from the second exhaust port 204, and then reaches the multiple air intake holes 20111 on the side of the accommodating cavity 200 through the air notches 20115 in the baffle 20114 on both sides of the fan bracket, enters the accommodating cavity 200 through the multiple 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] As an optional embodiment, the exhaust port 204 further includes a third exhaust port on the opposite side of the baffle 20114 from the first or second exhaust port, i.e., the exhaust ports 204 shown in Fig. 18b, where the III-path airflow enters through the third exhaust port, and the III-path airflow directly reaches the plurality of air intake holes 20111 on the side of the receiving cavity 200 from the third exhaust port, enters the receiving cavity 200 from 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. This can improve the efficiency of air replenishment.

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

[0099] In some embodiments, as shown in FIG. 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 outsides 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, a top end of each of the spacers 20112 includes at least one notch 20113 communicating with the plurality of air flow paths. The multiple air passages formed by the multiple spacers 20112 can ensure the uniformity of the airflow entering the receiving cavity 200, and prevent a part of the airflow from reaching the outside of the air suction holes 20111, i.e., entering the receiving cavity 200 but not immediately reaching the dust box, resulting in airflow loss, and at the same time, the lost airflow forms convection with the I-IV path airflow, affecting the efficiency of airflow entering the dust box. After providing the multiple spacers 20112 to form a communication structure, the multiple air passages can reach the receiving cavity 200 more uniformly through the multiple air suction holes 20111, and enter the dust box more efficiently.

[0100] In some embodiments, as shown in Fig. 21, the first intake door 3013 and the second intake door 3014 are respectively provided at asymmetric positions with respect to the first side wall 3015 and the second side wall 3016, to avoid the airflows entering from two sides being directly offset, and the intake airflows entering from two different directions cross each other, which helps to form an airflow vortex more quickly in the dust box during dust collection, to increase the swirling speed of the airflow entering the dust box, to greatly reduce the amount of dust remaining in the dust box, to reduce the dead angle of the airflow, and to improve the dust collection rate. In some embodiments, the second intake door 3014 is provided at a position close to 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, which further increases the swirling speed of the airflow entering the dust box. In some embodiments, the second intake door 3014 is provided adjacent to the rear wall of the dust box, and the first intake door 3013 is provided adjacent to the front wall of the dust box, so as to further increase the swirling speed of the airflow entering the dust box. Here, in an assembled state, the front wall of the dust box is a side wall facing the forward direction of the automatic cleaning device of the dust box, and the rear wall of the dust box is a 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, so as to further increase the swirling speed of the airflow entering the dust box. Here, the first rotating shaft and the second rotating shaft are rotating shafts on which the first intake door 3013 and the second intake door 3014 are actually provided, and may rotate around the position where the first rotating shaft and the second rotating shaft 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 order to open and close the first intake door 3013 and the second intake door 3014 during the actual dust collection process, 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 a description of this is omitted 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 ellipse, and an elongated shape, or a combination thereof, and are not limited thereto. In some embodiments, the first intake door 3013 has a rectangular structure, and the long side of the first intake door 3013 is arranged along the vertical direction, and the second intake door 3014 has a rectangular structure, and the long side of the second intake door 3014 is arranged 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 a vertical vortex and a horizontal vortex, which lifts up dust from multiple angles in all directions, efficiently improving the dust collection rate, and further increasing the swirling speed of the airflow entering the dust box. Furthermore, the first intake door 3013 and the second intake door 3014 are designed to open inward. As shown in FIG. 21, when the first 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 when airflow flows in, it is blown directly toward the front wall of the dust box. When the second 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 when airflow flows in, it is blown directly toward the bottom of the dust box. The airflows flowing in from the two dampers do not collide with each other, and a swirling airflow is formed. This accelerates the rotation of the dust in the dust box and promotes the circulation of the dust to the dust outlet so that it can be sent 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 suction and a dust outlet during dust collection, and the dust inlet during dust suction and the dust outlet during dust collection are provided as a single opening, reducing the number of openings and efficiently sharing existing openings, thereby reducing the probability of air leakage, and a filter is provided on the second opening 3012. The specific structure and installation method can be referred to the above embodiments, and the description will be omitted here. As shown in FIG. 22, the first opening 3011 and the second opening 3012 are substantially located on the central axis line in the front-rear direction of the automatic cleaning device, and this design structure allows the air flow path to be linear when dust is suctioned through the fan of the automatic cleaning device, avoiding the detouring of the airflow and improving the smoothness of the air flow path.

[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 rear in the forward direction of the automatic cleaning device. 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 at the rear wall of the connection between the first cavity 201 and the second cavity 202, and the dust suction port 203, the air outlet 208, the first opening 3011, and the second opening 3012 are all substantially located on the central axis of the automatic cleaning device in the front and 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 the effectiveness of the fan, and saves energy and reduces noise.

[0105] In some embodiments, the moving platform 100 includes a positioning device 1211 that is substantially on the central axis of the moving platform 100 in the forward and backward direction, and a protective cover 1212 that is arranged to cover the upper side of the positioning device 1211. A fan is arranged in the space below the second cavity 202, and the positioning device 1211, the protective cover 1212, the 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 substantially on the central axis of the automatic cleaning device in the forward and backward direction. In the related art, when there is a single air inlet, the intake airflow is not symmetrical, the dust inlet is usually offset, which looks bad, and the passage between the inlet and the outlet of the entire air flow path is not straight, which causes airflow blockage and loss, and at the same time affects the layout of other devices; after adding an air inlet, the air flow path structure is arranged on the central axis, and the existing dust collection method has the disadvantages of low dust collection rate and continuous dust collection. The existing technology has offset air flow path, which overcomes the technical drawback of fan power and suction force loss due to zigzag duct, and at the same time, the component arrangement space is greatly improved for aesthetic design. The port of the main brush module 153 is also located on the central axis, which ensures that the dust suction air flow path is not obstructed, reducing loss 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] As shown in FIG. 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 dirt in the dust box of the automatic cleaning device and is provided on the dust collection station base 710. The dust collection station base 710 includes a dust collection port 711, which is abutted against a port of the main brush module of the automatic cleaning device, and the dirt in the dust box of the automatic cleaning device enters 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, which is used to abut and seal the dust collection port 711 against the port of the main brush module of the automatic cleaning device and prevent dirt from leaking.

[0109] 24 is a schematic diagram showing a state after the automatic cleaning device provided by 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, the automatic cleaning device having an automatic dust collection function, and by asymmetrically providing two dampers in a dust box of the automatic cleaning device, the airflow entering the dust box forms a convection current, forming a vortex cyclone in the dust box, and smoothly sucking dust in the dust box into a dust collection station; and by providing a main brush module, a dust suction port, an air outlet, a first opening, and a second opening substantially on the central axis line of the automatic cleaning device in the front-to-rear direction, the speed of the airflow flowing through the dust box during dust suction is further increased, improving the dust suction efficiency, and at the same time, the dust in the dust box can be easily sucked into the dust collection station during dust collection.

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