[0023] 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, but not all of the embodiments. Based on the embodiments of the present disclosure, other embodiments obtained by those skilled in the art without any creative work are all included in the protection scope of the present disclosure.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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 other elements explicitly listed or inherent in those products or devices. Unless further limited, an element defined with the phrase "comprises" does not exclude the presence of other identical elements in a product or device that includes said element.

[0028] Selected embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0029] 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 man-machine interactive system 170.

[0030] The mobile platform 100 is configured to automatically move in a target direction on an operating surface. The operating surface may be a surface to be cleaned by an automatic cleaning device. In some embodiments, the automatic cleaning device may be a mopping robot, where the automatic cleaning device operates on a floor surface, and the floor surface is the operating surface. Alternatively, the automatic cleaning device may be a window cleaning robot, where the automatic cleaning device operates on the glass exterior surface of a building, and the glass is the operating surface. Alternatively, the automatic cleaning device may be a pipe cleaning robot, where the automatic cleaning device operates on the interior surface of a pipe, and the interior surface of the pipe is the operating surface. For purely illustrative purposes, the present disclosure will be described in terms of a mopping robot.

[0031] 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 front section 111 and a rear section 110.

[0032] The sensing system 120 includes a positioning device 121 located above the mobile platform 100, a buffer 122 located in the front portion 111 of the mobile platform 100, a cliff sensor 123 located at the bottom of the mobile platform, and sensing devices such as an ultrasonic sensor (not shown), an infrared sensor (not shown), a magnetometer (not shown), an accelerometer (not shown), a gyroscope (not shown), and an odometer (not shown), and provides various position information and movement status information of the equipment to the control system 130.

[0033] To more clearly describe the behavior of the automatic cleaning device, the following directions are defined: the automatic cleaning device can move on a floor surface through 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 rear 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 front portion of the automatic cleaning device tilts upward and the rear portion tilts downward, this is referred to as "pitch up," and when the front portion of the automatic cleaning device tilts downward and the rear portion tilts upward, this is referred to as "pitch down." Furthermore, 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 "right turn," and when the automatic cleaning device tilts to the left of the X axis, this is referred to as "left turn."

[0034] 2, cliff sensors 123 are provided at the bottom of the moving platform 100, in front and behind the drive wheel assembly 141, to prevent the automatic cleaning device from falling when retreating and to prevent damage to the automatic cleaning device. The "front" refers to the side in the same direction as the automatic cleaning device's travel, and the "rear" refers to the side opposite to the direction of travel of the automatic cleaning device.

[0035] Specific types of position determining device 121 include, but are not limited to, a camera, a laser ranging device (LDS), and the like.

[0036] 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.

[0037] For example, an ultrasonic sensor may be used to determine whether the surface to be cleaned is carpet, 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.

[0038] A buffer 122 is provided on the front portion 111 of the mobile platform 100, and when the drive wheel assembly 141 propels the automatic cleaning device to run on the floor surface during the cleaning process, the buffer 122 detects one or more events (or objects) in the running path of the automatic cleaning device via a sensor system, for example, an infrared sensor, and the automatic cleaning device may control the drive wheel assembly 141 in response to the event (or object), for example, an obstacle, a wall, detected by the buffer 122, so that the automatic cleaning device responds to the event (or object), for example, moves away from the obstacle.

[0039] The control system 130 is provided on a circuit board within the mobile platform 100 and includes an arithmetic processor, such as a central processing unit (CPU) or an application processor, in communication 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.

[0040] Specifically, the control system 130 combines distance and speed information fed back from the buffer 122, cliff sensor 123, and 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, been positioned on 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 needs 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.

[0041] 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. For more precise control of the device operation, the drive system 140 preferably comprises a left drive wheel assembly and a right drive wheel assembly, respectively. The left and right drive wheel assemblies are symmetrically arranged along a horizontal axis defined by the mobile platform 100.

[0042] In order for the automatic cleaning device to move more stably on the floor surface or have higher mobility, the automatic cleaning device may include one or more steering assemblies 142, and the steering assembly 142 may be a driven wheel or a driving wheel, and its structural form may be a universal wheel, and the steering assembly 142 may be located in front of the driving wheel assembly 141.

[0043] 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 via charging electrodes provided on the side or bottom of the main body for charging.

[0044] The man-machine interactive system 170 may include keys on a host panel that can be used by the user to select functions, 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 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, providing the user with a richer and more user-friendly range of functions.

[0045] As shown in FIG. 2, cleaning module 150 may include a dry cleaning module 151 .

[0046] 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 the dust into the dust box via suction gas generated by the fan that passes through the dust box. The dust removal capacity of a vacuum cleaner is characterized by its dust pickup efficiency (DPU). DPU is affected by the structure and materials 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 parts, 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. This directly and effectively reduces the energy required, e.g., a machine that can clean 80 square meters of floor space on a single charge can be upgraded 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 performance is the most obvious and important user experience, allowing users to directly conclude whether the machine cleans or wipes clean. The dry cleaning module may further include a rotating shaft side brush 152, the rotating shaft of which is angled relative to the floor surface to move dirt to the roller brush area of ​​the cleaning module 150.

[0047] 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, wherein the wet cleaning module includes a water tank, a cleaning head, a drive unit, etc., wherein water from the water tank flows along a water circuit to the cleaning head, and the cleaning head cleans at least a portion of the operating surface under the drive of the drive unit.

[0048] Existing automatic cleaning devices have a complex casing layout frame structure, many parts, long assembly time, and cumbersome 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 soiled items 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.

[0049] In this regard, the embodiments of the present disclosure provide an automatic cleaning device without a flip cover, which can simplify unnecessary components of the automatic cleaning device while expanding the design space of the dust box and its storage cavity, and achieve the same technical effects with the same structure, so some technical effects will not be repeated in this specification. Specifically, the present disclosure provides an automatic cleaning device, which includes a moving platform 100 configured to automatically move on an operating surface, as shown in FIG. 3, and the moving platform 100 includes a storage cavity 200, and in some embodiments, the storage cavity 200 is located on a rearward-biased side in the forward direction of the automatic cleaning device, and 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, wherein 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 depth of the first cavity 201 is greater than the depth of the second cavity 202. The first cavity 201 and the second cavity 202 are arranged adjacent to each other in the forward direction of the automatic cleaning device, and the larger part of the dust box in terms of volume and weight 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 and making the center of gravity of the entire cleaning device more stable, 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 and directly aligned with the dust box, allowing dust to enter the dust box directly from the dust suction port, reducing the movement of dust into the interior of the device and preventing dust contamination of the interior of the device.The depth of the first cavity 201 is greater than the depth of the second cavity 202, allowing the dust box and the dust box top cover to be housed as separate structures and facilitating the 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, an air outlet 208 is provided on the rear wall of the connection between the first cavity 201 and the second cavity 202, and 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. 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 air is filtered by the dust box filter before being discharged through the air outlet 204.

[0050] In some embodiments, the dust box 300 includes a receiving portion 301 and a top cover 302 located above the receiving portion 301, and the top cover is fixedly connected to the receiving portion 301. The fixed connection method may include, but is 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 is substantially the same as that of the first cavity 201.

[0051] The roller brush, which is in contact with the floor surface to a certain extent, sweeps up dust on the floor surface and is wound up in front of the dust suction port 203 between the roller brush and the dust box 300 under the action of the negative pressure airflow generated by the fan. The dust is then sucked into the dust box 300 by the suction airflow generated by the fan that passes through the dust box 300, and is isolated inside the dust box 300 by the filter 500, and the filtered air flows into the fan.

[0052] Typically, the receiving section 301 of the dust box 300 has a first opening 3011 at the front side of the dust box, which is aligned with the dust suction port 203, and a second opening 3012 at the rear side of the dust box, with the filter 500 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 remove, install, and clean the filter. Here, the front side refers to one side in the X direction along the forward movement direction of the automatic cleaning device after the dust box 300 is assembled into the receiving cavity 200, and the rear side refers to the side opposite to the forward movement direction of the automatic cleaning device in the X direction.

[0053] In some embodiments, the top cover 302 includes a first portion 3021 covering the storage portion 301 and a second portion 3022 protruding from the storage portion 301 and extending outward, and when the dust box 300 is assembled to the storage cavity 200, the storage portion 301 and the first portion 3021 of the top cover 302 are accommodated in the first cavity 201, and the second portion 3022 of the top cover 302 is accommodated in the second cavity 202. The top cover 302 roughly matches the top end portion of the first cavity and the structure of the second cavity, which ensures that the dust box 300 is stably installed in the receiving cavity 200 and prevents the dust box from shaking due to vibrations during the operation of the automatic cleaning device. At the same time, the dust box top cover precisely covers the position of the receiving section and the fan, so that the upper surface of the dust box top cover is roughly 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 spatial options for the design of each component, including the receiving section, on the underside of the top cover, making it easier to arrange the positions of different components, improving the selectivity of the dust box volume and allowing specific sizes to be set as needed, without affecting the overall opening size of the receiving cavity and reducing molding costs.

[0054] In some embodiments, the first portion 3021 of the top cover 302 includes a lip 30211 that protrudes outward from the edge contour of the storage compartment. The storage cavity 200 includes a step 205 that extends around the top edge of the storage cavity, and the step 205 is configured to receive at least a portion of the lip 30211 and at least a portion of the outer edge of the second portion, such that the top surface of the top cover is substantially flush with the top surface of the moving platform. The step 205 that extends around the top edge of the storage cavity 200 can entirely receive the edge of the top cover 302, allowing the top cover 302 to be received in the storage cavity 200 in a substantially seamless manner, preventing foreign objects from falling directly onto the seam at the edge of the dust box and causing the dust box to become caught, while at the same time ensuring the appearance of the top cover as the top surface of an automatic cleaning device.

[0055] 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 or 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.

[0056] In some embodiments, a groove 2021 is provided on the underside of the second cavity 202, and the groove 2021 approximately matches the contour of the support structure 3023, so that when the second part 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 approximately horizontal.

[0057] 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 shape of the top cover is at least one of a D-shape, a rectangle, a square, a circle, an oval, a triangle, a square, a pentagon, a hexagon, a heptagon, or an octagon, or a combination thereof. The symmetrical arrangement allows the appearance of the device to be maintained without being covered by an outer cover, and also makes it easier to install and remove the dust box.

[0058] In some embodiments, the first cavity 201 includes a first locking member 701, the second cavity 202 includes a second locking member 72, the first portion 3021 of the top cover includes a first locking member 601, and the second portion 3022 of the top cover includes a second locking member 602, wherein 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.

[0059] 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 greater than the depth of the second cavity, and after the dust box is assembled into the accommodating cavity, the upper surface of the top cover of the dust box is approximately 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.

[0060] Existing automatic cleaning devices are equipped with pop-up and non-pop-up dustbins, pop-up dustbin top flaps, and flip mechanisms. When installing or removing a dustbin, the top flap must be opened and the dustbin must be pressed 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 usability. 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 do not fit comfortably with the fingers when operating them, resulting in an overall poor user experience.

[0061] In this regard, an 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. Although some structural features of this embodiment are simplified compared to the above-described embodiment, the same structure has similar technical effects, and some of the technical effects will not be repeated in this specification. Specifically, as shown in Figures 1 to 5 and 7, the automatic cleaning device is configured to move automatically on an operating surface and includes a moving platform 100 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, and 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 approximately on the central axis of the top cover, wherein the first locking mechanism 610 includes at least a first grommet recess 603 and a first locking member 601, the first locking member 601 is located within the first grommet recess 603, and the first locking member 601 can 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 a first partial edge of the top cover, the first grommet recess 603 has a sufficient depth in the Z direction, and the height of the first locking member 601 is lower than the surface of the top cover. The first grommet recess 603 also provides a sufficient elastic space in the X direction, providing sufficient movement space for the first locking member 601 to elastically move inward.

[0062] In some embodiments, the first locking member 601 includes a first resilient arm 6011, a first grommet portion 6012, and a first fastening portion 6013, wherein the first resilient arm 6011 extends upward from the bottom of the first grommet recess 603, the first grommet portion 6012 is provided at the upwardly extending end of the first resilient arm 6011, and the first fastening portion 6013 extends along the lateral 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 laterally disposed above the first elastic arm 6011. The first grommet portion 6012 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 have an arc-shaped structure, i.e., its projection on the horizontal plane is arc-shaped. The grommet surface facilitates manual operation and provides a finger shape that is more ergonomic. In some embodiments, the first fastening portion 6013 is a pair of sheet structures symmetrically disposed along both sides of the first elastic arm 6011. The sheet structures have a width from the base to the free end that narrows from larger to smaller 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 an organic elastic material.

[0063] In some embodiments, as shown in Fig. 8, Fig. 8 is an enlarged schematic view of the first locking member in A of Fig. 3a, in which a first locking member 701 is provided at a location on the inner wall of the receiving cavity 200 that approximately corresponds 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.

[0064] In some embodiments, a first recess 206 is provided in the inner wall of the receiving cavity at a location 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 applies force through the first recess 206 to pull the first locking member 601 out of the through-hole. The cooperation of the first recess 206 and the first grommet recess 603 makes the access operation by the finger easier and more convenient.

[0065] In some embodiments, as shown in FIG. 9a , the locking mechanism further includes a second locking mechanism 620, which includes a second grommet recess 605 and a second locking member 602, the second grommet recess 605 having a notch, for example, an arc-shaped or rectangular notch, formed on the inner side along approximately the midline of the top cover second part 3022, which is easy for a finger to reach for snapping operation, the second locking member 602 being located below the second grommet recess 605, the second grommet recess 605 providing sufficient space for a finger to control the second locking member 602, and the second locking member 602 elastically moving 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 fastening portion 6023. The second elastic arm 6021 is located below the second grommet recess 605. The second elastic arm 6021 includes two symmetrical portions. Each second elastic arm 6021 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. The opening direction of the second grommet recess 605 is, as shown in FIG. 9a, direction A, which is from the center of the top cover to the outside, and in this embodiment, it is also toward the rear of the dust box top cover. The two portions of the second elastic arm 6021 are symmetrically connected to form two approximately "box"-shaped structures. The second grommet portion 60 22 is connected to two symmetrically arranged second elastic arms 6021, specifically, the second grommet portions 6022 are arranged above the two second elastic arms, as shown in Figures 9b and 9c, where Figure 9c is an enlarged view of the second grommet portion at C in Figure 9b, and the bottom of the second grommet portion 6022 is provided with a bottom surface 60221 that protrudes outward and a grommet surface 60222 that extends upward along the bottom surface, and the grommet surface extends to a position where it is approximately flush with the top cover, and the grommet surface may have an arc-shaped structure, which facilitates manual operation and allows fingers to apply force conveniently, and optionally the second grommet portion 6022 is molded integrally with the symmetrically arranged second elastic arms 6021, and the second fastening portion 6023 is provided on the horizontally extending portion of the second elastic arm. The second fastening portions 6023 are arranged symmetrically along both sides of the pair of second elastic arms 6021, and are, for example, protrusions or sheet structures extending along the A direction. As an optional embodiment, each of the second fastening portions 6023 has a groove extending inward from the end of the second fastening portion 6023, and the groove can prevent the second fastening portion from deforming significantly after the entire second fastening 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 to and fixed on an end surface of the support structure. The second grommet portion 6022 is exposed from the second grommet recess 605 in the X direction. When unlocking, a finger reaches the second grommet recess 605 and presses the second grommet portion 6022, applying force toward the inside of the dust box along the X axis to elastically contract the second fastening portion 6023 inward, and the second fastening portion 6023 pops up from the bottom of the second locking member 702, thereby achieving unlocking. The second elastic arm 6021 as a whole is generally formed of an elastic material such as plastic or an organic elastic material.

[0066] In some embodiments, as shown in Figure 10, which is an enlarged view of the second locking member 702 in Figure 3bB, the second locking member 702 is provided at a location on the inner wall of the receiving cavity 200 that approximately corresponds 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 the second catches 602 extend from 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 catches.

[0067] 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 equidistantly on the rear wall of the second cavity 202 and located above the second recess 207. The second recess 207 is configured to accommodate the second locking member 602 when the dust box 300 is placed in the receiving cavity 200, thereby allowing the entire dust box to be well placed in position in the receiving cavity 200.

[0068] In some embodiments, the top cover includes a first portion covering the receiving portion and a second portion protruding from the receiving portion and extending outward, 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, and the second locking member 602 is provided on the support structure 3023. As shown in FIG. 4 , the symmetrically provided support structures 3023 form an inward compression space in the X direction, and when the second elastic arm 6021 is connected to the symmetrical support structure 3023, a sufficient elastic space is ensured to respond to an applied inward force.

[0069] 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 popping up and tilting. At the same time, the elastic structure is simple, and elastic unlocking can be achieved by forming the elastic arms out of elastic material, eliminating the risk of complex unlocking devices such as springs being easily damaged.

[0070] 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 is 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 catch 6013 on 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 to lock the dustbin.

[0071] 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.

[0072] 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 dotted adhesive seals the frame and the filter medium. A sealing strip is then attached to the frame to seal the gap between the filter and the dust box. Therefore, the structure of the dust box filter part is complicated, the filter installation process is cumbersome, labor and cost are wasted, and the adhesive used for sealing is uneconomical and environmentally unfriendly.

[0073] In this regard, an embodiment of the present disclosure provides an automatic cleaning device, the automatic cleaning device being configured to automatically move on an operating surface, the automatic cleaning device comprising: a moving platform including a storage cavity; and a cleaning module including a dust box, the dust box being detachably attached to the storage cavity, the dust box including a dust box filter, the dust box filter being applied to the dust box of the automatic cleaning device, the assembly process of the dust box filter being simplified, the embodiment has some simplified structural features compared to the above-mentioned embodiment, but the same structures have similar technical effects, some of which will not be described here. Specifically, as shown in Figures 11 and 12, a dust box filter 500 includes a soft rubber frame 501, the soft rubber frame including at least one soft rubber protrusion 5011 for sealing the assembly gap with the dust box during assembly, and a filter medium 502 fitted in the soft rubber frame 501, the soft rubber frame 501 being 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, in which the filter material is pre-fitted into the frame, and a rubber sleeve is fitted over the fitted frame combination to integrally form a plurality of desired sealing protrusions. Alternatively, a two-shot injection molding process can be used, in which the hard rubber frame body is first injected, the filter material is fitted into the frame body, and then soft rubber is injected to form the inner and outer sealing protrusions.

[0074] The soft rubber frame may have a rectangular, square, oval, circular, polygonal, etc., but is not limited to these structures. In some embodiments, as shown in Figures 11 and 12, the soft rubber frame has a rectangular structure, and the rectangular soft rubber frame includes two opposing soft rubber frame first side walls 50111 and two soft rubber frame second side walls 50113, and the soft rubber protrusions include a first protrusion 5011 distributed on the outer peripheral surface of one of the soft rubber frame first side walls 50111 and a second protrusion 5015 distributed on the outer peripheral surface of the other of the soft rubber frame first side walls 50111, and a rectangular structural frame is surrounded and formed by the pair of soft rubber frame first side walls 50111 and the pair of soft rubber frame second side walls 50113, and a filter medium is fitted inside the rectangular structural frame.

[0075] 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 of the soft rubber frame. Because the first protrusion 5011 and the second protrusion 5015 have a soft rubber structure, when the dust box filter is assembled into the dust box, the first protrusion 5011 and the second protrusion 5015 are pressed 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 fully in contact with the inner wall extending along a substantially 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.

[0076] In some embodiments, as shown in Fig. 14, at least one of the first protrusion and the second protrusion has an inverted structure, which is configured to seal the assembly gap between the soft rubber frame and the dust box and prevent the dust box filter from falling out of the dust box. Specifically, the inverted structure is an arc-shaped structure that is inclined toward the side opposite to the assembly direction of the dust box filter. The inverted structure facilitates the dust box filter to extend with friction into the dust box assembly opening, incline toward the side opposite 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.

[0077] In some embodiments, the second side wall of the soft rubber frame further includes at least one third protrusion 5012, and the third protrusion 5012 is distributed on the outer peripheral surface of at least one second side wall 50113 of the soft rubber frame 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 into the dust box, the third protrusion 5012 on the outer circumferential surface of one of the soft rubber frame second side walls 50113 of the frame structure has a slightly long structure and extends into the recess in the dust box side wall to function as a fastener and prevent the dust box filter from falling off. At the same time, when assembling the dust box filter, the slightly long third protrusion 5012 is first inserted into the recess in the dust box side wall, 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 surface of the second side wall 50113 of another soft rubber frame of the frame structure have a smoother structure. When the dust box filter is assembled into the dust box, the third protrusions 5012 on this side are interferingly locked into the dust box side wall elastic structure 5013 to prevent the dust box filter from falling off. Here, the elastic structure 5013 is roughly S-shaped and includes an inner recess for accommodating the third protrusions 5012 and an outer protrusion locked onto the third protrusions 5012. The outer protrusion can elastically move under the action of external force to be locked onto the third protrusions 5012. Figure 15 is a diagram of the installation structure when the dust box filter is 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 peripheral surface of the soft rubber frame second side wall and is configured to prevent the dust box filter from being installed too deep or too shallow 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 the pillow position 5014 provided at the 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 does not abut against the pillow position 5014 on the dust box side frame, as shown in Figure 15, it is considered not assembled in place, and therefore the dust box filter can be prevented from being installed too shallowly in the dust box.

[0078] 13a and 13b, the soft rubber frame further includes a sagging prevention protrusion 509, which is provided on the outer circumferential surface of the second side wall of the soft rubber frame and configured to prevent the dust box filter from being installed backwards. A recess is provided in the dust box at a position corresponding to the sagging prevention protrusion 509, and when the dust box filter is installed properly, the sagging prevention protrusion 509 enters the recess and the dust box filter is assembled properly. When the dust box filter is installed backwards, the recess is not present on the other side of the dust box, and the sagging prevention protrusion 509 prevents the dust box filter from being assembled, thereby preventing sagging and indicating that the dust box filter is installed backwards.

[0079] In some embodiments, as shown in Figures 3a and 3b, the receiving cavity 200 includes a first cavity 201 and a second cavity 202, which are adjacent to each other in the forward direction of the automatic cleaning device, and the depth of the first cavity 201 is greater 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 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, a grill structure is provided at the air outlet 208.

[0080] As shown in Figures 11 and 12, the soft rubber frame further includes a sealing inner lip 507, which is provided on the first end surface 50116 of the soft rubber frame 501 around the filter material 502 and is configured to achieve 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 closer to the inner wall of the dust box within the second opening, has a substantially planar structure, and abuts against the first end surface 50116 of the soft rubber frame 501 to be assembled to the soft rubber frame. A sealing outer lip 506 is provided on the second end surface 50115 of the soft rubber frame 501 around the filter material 502 and is configured to seal the dust box filter and 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 surface 50116 or the second end surface 50115, 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 can seal the dust box filter and 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 of the dust box filter The side lip 506 is pressed between the dust box filter and the outside of the grill of the air outlet 208 of the accommodating cavity 200, sealing the dust box filter and the assembly surface of the fan bracket, and 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 surface of the dust box filter 500 and the dust box air outlet assembly surface, and between the outer end surface 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 on the inside and outside of the dust box filter to meet the air duct sealing requirements. The soft rubber frame 501 serves as the carrier, and the inner sealing lip 507 and outer sealing lip 506, which also have a certain degree of flexibility, serve as the sealing structure, resulting in a tighter contact, sealing and fit, a more satisfactory fit, and a stronger sealing effect, which can ensure the airtight performance of the entire air duct and better guarantee the functions of the cleaning device such as dust collection and dust discharge through negative pressure.

[0081] 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 assembly outer edge of the dust box and is locked on the outer edge of the dust box, preventing the dust box filter from being installed too deeply in the dust box.

[0082] 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 installed in a predetermined position, the magnetic device may be a magnet or other electromagnetic element, and an inductive magnetic device is installed in the magnetic device mounting hole 504, and the magnetic device mounting hole 504 has a sufficient depth so that the magnetic device can be installed in a fixed position inside the filter, and when the entire filter is installed in the fixed position, it can be detected by a Hall sensor to ensure that the filter is installed in a predetermined position.

[0083] 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 and further encloses the magnetic device when pressed.

[0084] 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 of the grommet 505 is not limited and may be semicircular, square, rectangular, etc.

[0085] In some embodiments, as shown in FIG. 12 , the soft rubber frame further includes a hollow structure 508, which is provided on the first soft rubber frame side wall and / or the second soft rubber frame side wall of the frame and is configured to reduce the overall weight of the frame, and the hollow structure 508 may be a plurality of inwardly recessed fastening holes, and the shape of the fastening holes is not limited and may be circular, square, rectangular, irregular, etc.

[0086] 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 at the same time cooperates with structures such as the first protrusion, the inner sealing lip, and the outer sealing lip, achieving the effect of tightly sealing the filter and the assembly surface during assembly, avoiding the traditional process of manually gluing the assembly parts with dotted adhesive after the filter is attached, simplifying the process and reducing the number of assembly parts, while at the same time reducing costs, not requiring adhesive bonding, odorless, and more environmentally friendly.

[0087] 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.

[0088] 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.

[0089] 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 airway entering the automatic cleaning device, and the airway is obstructed by the equipment structure and not smooth. This makes it difficult for the dust collection station to suck all of 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 fan in the dust collection station needs to be increased, resulting in louder noise and more energy consumption.

[0090] In this regard, the embodiment of the present disclosure further provides an automatic cleaning device with dust collection function, and improves the airway structure of the automatic cleaning device so that the airflow can more easily enter the dust box during the dust collection process, 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 similar technical effects, and some technical effects will not be described 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 mobile platform 100, which is configured to move automatically on an operating surface, and which 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, which is located approximately at the rear half of the mobile platform in the forward direction and is recessed inward, and the drive wheel assembly 141 is located on the lower casing of the mobile platform 100 as described above and is used to provide forward driving 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, and the dust box 300 is detachably assembled to the storage cavity 200, and some of the structure of the dust box 300 can be referred to in the above embodiment and will not be repeated here.The dust box 300 further includes a first air inlet 3013 and a second air inlet 3014, the first air inlet 3013 and the second air inlet 3014 being respectively located on a first side wall 3015 and a second side wall 3016 of the dust box, the first air inlet 3013 and the second air inlet 3014 being configured to provide intake airflows in two different directions during the dust collection process, contributing to the formation of an airflow vortex in the dust box during dust collection, and reducing the airflow in the dust box. The installation of two air inlets increases the intake speed and improves the formation efficiency of the air vortex, where the sources of the intake airflow 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 sidewall of the mobile platform, and airflow IV entering through the gap in the drive wheel assembly 141. The configuration of multiple sets of intake airflows increases the intake volume and intake speed of the automatic cleaning device, improving the dust collection strength and efficiency of the dust collection station, and further reducing the dead airflow space in the dust box, reducing the amount of dust remaining and improving the dust collection rate.

[0091] After the automatic cleaning device has completed its dust collection, when it returns to the dust collection station to perform dust collection, the fan of the dust collection station starts to suck in the dust inside the dust box. During the suction process, the airflow passes through multiple flow paths and enters the dust box through the first air inlet 3013 and the second air inlet 3014, and is then sucked in through the dust collection port by the dust collection station together with the dust. In the dust collection state, the main cleaning brush of the automatic cleaning device moves in the reverse direction as the fan of the dust collection station is started, and the automatic cleaning device enters the "dust discharge" state. 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 of the dust box to rotate and fly up. The dust collection fan of the dust collection station is started, and a specific airway connects the main brush, the first opening 3011 of the dust box, and the internal cavity of the dust box, and then the suction force sucks the dust in the internal cavity of the dust box into a dust storage container or bag inside the dust collection station.

[0092] 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. Specifically, as shown in FIG. 16, 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 cover 940 and the top surface of the moving platform 100, and the airflow entering through the gap between the cover 940 and the positioning element 1211. In the present disclosure, when the cover 940 and the positioning element 1211 are assembled, an air gap is formed between the cover 940 and the top surface of the moving platform 100, and between the cover 940 and the positioning element 1211, by a support structure such as a protrusion. The suction of the fan of the dust collecting station creates a negative pressure in the dust box 300 that is in fluid communication with the fan of the dust collecting station. The first air inlet 3013 and the second air inlet 3014 are opened toward the inside of the dust box, guiding the airflow outside the dust box to enter, and a negative pressure is also created inside the moving platform, and the gas outside the moving platform is diverted between the cover 940 and the The airflow is guided to enter the interior of the device through the airflow gaps formed between the cover 940 and the top surface of the moving platform 100 and between the cover 940 and the positioning element 1211. Compared to conventional sealing structures, the airflow gaps formed between the cover 940 and the top surface of the moving platform 100 and between the cover 940 and the positioning element 1211 increase the airflow passages, ensuring sufficient airflow to enter 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 airflow space in the dust box, reducing dust residue, and improving the dust collection rate. More importantly, guiding the airflow to pass near the positioning element 1211 helps to remove excess heat generated by the positioning device during operation, playing 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, and is safer and friendlier to the airways inside the device.

[0093] 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 through the assembly gap of the main brush module 153 at the bottom of the lower casing of the moving platform 100. Here, during the assembly of the device, a protrusion, a groove, or a self-contained assembly gap forms an edge gap between the main brush module 153 and the drive wheel assembly 141. The suction of the fan of the dust collecting station creates a negative pressure inside the moving platform, and the gas outside the moving platform is drawn through the edge gap of the main brush module 153. Compared with conventional sealing structures, more airflow paths can be formed in the edge gaps of the main brush module 153, which further ensures that sufficient airflow enters the dust box and further improves the air intake volume and intake speed of the dust box, thereby improving the dust collection strength and dust collection efficiency of the dust collection station, while reducing the dead space of the airflow in the dust box, reducing dust residue and improving the dust collection rate. Furthermore, the distance that airflow II travels to reach the two air inlets of the dust box is short and the duct is smooth, which further improves the airflow replenishment speed and ensures dust collection efficiency.

[0094] In some embodiments, the rear wall of the moving platform 100 is provided with an exhaust port 204, and as shown in FIG. 3a, the plurality of sets of intake airflows further includes an airflow III entering through the exhaust port 204 in the dust collection state. As shown in FIG. 18a, the exhaust port 204 is in the dust collection state, and a negative pressure is formed inside the moving platform by the suction of the fan of the dust collection station, which 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, the gas is guided through the exhaust port 204. The air enters both sides of the fan bracket from the air intake duct 201104, then enters the outside of the side wall of the storage cavity through the air inlet 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 storage side wall, further ensuring sufficient airflow into 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 the dead airflow space in 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 inlet ports, allowing for smoother airflow replenishment and reducing interference with the airflow from external equipment or the environment that comes into contact with or fits into the cleaning device, resulting in safer and more efficient airflow replenishment. In some embodiments, the air inlet notches 20115 are provided at the bottom of the sealing baffles 20114 to reduce the impact of the airflow on other components.

[0095] 18a, the airflow entering the dust box further includes airflow IV entering through the gaps in the drive wheel assembly 141. The drive wheel is provided with an air intake passage, and the airflow entering the casing through the gaps in the edges at the bottom of the drive wheel directly enters both sides of the accommodating cavity through the air 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 air circulation passages of the dust box, and providing a larger incoming airflow.

[0096] 18a, the airflows of the I-II and IV paths are divided into two parts after entering the casing of the moving platform 100, with the airflows of the I and II paths forming the first part and the airflow of the IV path forming the second part. Here, the airflow of the first part, the airflow of the I path, enters through the gap between the cover 940 and the top surface of the moving platform and the gap between the cover 940 and the positioning element 1211, and directly reaches the front of the receiving cavity 200. The airflow of the II path enters through the gap between the main brush and the lower housing, passes through the opening around the main brush driving motor, and reaches the front wall of the receiving cavity. As shown in FIG. 18a, due to the obstruction of the front wall 2010 of the receiving cavity 200, the airflow cannot directly reach the side of the receiving cavity 200, and instead passes through the ducts 209 on both sides of the front wall to reach the side of the receiving cavity 200. 19 , in some embodiments, the upper outer side of the front wall of the storage cavity 200 includes a duct 209, and airflow I entering through the gap at the top of the moving platform 100 and airflow II entering through the gap in the main brush module 153 reach the plurality of air intake holes 20111 on the side of the storage cavity 200 through the duct 209, enter the storage cavity 200 from the plurality of air intake holes 20111, and then enter the dust box through the first air inlet 3013 and the second air inlet 3014. A second partial airflow IV reaches the plurality of air intake holes 20111 on the side of the storage cavity 200 directly from the air intake passage on the rear side above the drive wheels, enters the storage cavity 200 from the plurality of air intake holes 20111, and then enters the dust box through the first air inlet 3013 and the second air inlet 3014.

[0097] 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 top and bottom surfaces and side walls of the casing, the baffles 20114 seal the fan bracket 20116 at the rear end of the moving platform, and 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 will exhaust air through some exhaust ports 204 that communicate with the air exhaust pipe, i.e., the first exhaust ports, through the air exhaust pipe, and when collecting dust, the fan Air is drawn in through other exhaust ports 204 around the above-mentioned some of the exhaust ports 204, i.e., the second exhaust ports. That is, the second exhaust ports are mostly intake ports that do not directly communicate with the fan air exhaust pipe, and air inlet notches 20115 are provided on the baffle 20114. Therefore, the airflow of path III enters the inside of the moving platform casing through the second exhaust port 204, and then passes through the air inlet notches 20115 in the baffles 20114 on both sides of the fan bracket to the plurality of air inlets 20111 on the side of the receiving cavity 200, and then enters the receiving cavity 200 through the plurality of air inlets 20111, and then enters the dust box through the first air inlet 3013 and the second air inlet 3014.

[0098] As an optional embodiment, the air outlet 204 may further include a third air outlet on the side of the baffle 20114 opposite to the first or second air outlet, i.e., the air outlets 204 shown in FIG. 18b, whereby the air flow 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 inlet 3013 and the second air inlet 3014, thereby improving air replenishment efficiency.

[0099] 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 inlet of the automatic cleaning device.

[0100] 20 , the storage cavity 200 further includes a third side wall 2011 corresponding to the first side wall 3015 of the dust box and a fourth side wall 2012 corresponding to the second side wall 3016 of the dust box, the third side wall 2011 and the fourth side wall 2012 each having a plurality of air intake holes 20111, the plurality of air intake holes 20111 covering at least a portion of the first air inlet 3013 and the second air inlet 3014. The third side wall 2011 and the fourth side wall 2012 of the storage cavity 200 each include a plurality of spacers 20112 on their outer sides, the plurality of spacers 20112 forming a plurality of air passages. In some embodiments, a top end of each spacer 20112 includes at least one notch 20113 communicating with the plurality of air passages. The multiple air passages formed by the multiple spacers 20112 can ensure uniformity of the airflow entering the receiving cavity 200 and prevent a portion of the airflow from reaching the outside of the air intake holes 20111, i.e., preventing the airflow 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 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 intake holes 20111 and enter the dust box more efficiently.

[0101] 21, the first air inlet 3013 and the second air inlet 3014 are located asymmetrically with respect to the first side wall 3015 and the second side wall 3016 of the dust box, 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 air space, and improves dust collection efficiency. In some embodiments, the second air inlet 3014 is located near the lower edge of the second side wall 3016, and the lower edge of the second air inlet 3014 is lower than the lower edge of the first air inlet 3013, thereby further increasing the swirling speed of the airflow entering the dust box. In some embodiments, the second air inlet 3014 is located adjacent to the rear wall of the dust box, and the first air inlet 3013 is located adjacent to the front wall of the dust box, thereby further increasing the swirling speed 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 tail of the automatic cleaning device relative to the front wall. In some embodiments, the first air inlet 3013 rotates approximately around a first rotation axis, and the second air inlet 3014 rotates approximately around a second rotation axis, and the first rotation axis is approximately perpendicular to the second rotation axis, thereby further increasing the swirling speed of the airflow entering the dust box. Here, the first rotation axis and the second rotation axis may be rotation axes actually provided at the first air inlet 3013 and the second air inlet 3014, or may rotate about the positions of the first rotation axis and the second rotation axis via an elastic drive member.

[0102] The first air inlet 3013 and the second air inlet 3014 described in this embodiment are plate surfaces that cover the openings in the first side wall of the dust box and the second side wall of the dust box. In the actual dust collection process, in order to realize the opening and closing of the first air inlet 3013 and the second air inlet 3014, it is necessary to add elastic members connected to the first air inlet 3013 and the second air inlet 3014, and fixing structures fixed to the outer surfaces of the first side wall of the dust box and the second side wall of the dust box, and the description thereof will be omitted here.

[0103] In some embodiments, the shapes of the first air inlet 3013 and the second air inlet 3014 may be at least one of, or a combination of, a rectangle, a square, a circle, an ellipse, and an elongated shape, including, but not limited to, a rectangle, a square, a circle, a ellipse, and an elongated shape. In some embodiments, the first air inlet 3013 has a rectangular structure, and the long side of the first air inlet 3013 is arranged along the vertical direction, and the second air inlet 3014 has a rectangular structure, and the long side of the second air inlet 3014 is arranged along the horizontal direction. By arranging the first air inlet 3013 and the second air inlet 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 inlet 3013 and the second air inlet 3014 are designed to open inward. As shown in FIG. 21, when the first air inlet 3013 opens inward, the damper is half-open, and the damper opening faces the front wall of the dust box, so that when air flows in, it is blown directly toward the front wall of the dust box. When the second air inlet 3014 opens inward, the damper is also half-open, and the damper opening faces the bottom of the dust box, so that when air flows in, it is blown directly toward the bottom of the dust box. The air flows from the two dampers do not blow against each other, but form a swirling airflow, which accelerates the rotation of the dust inside the dust box and promotes the circulation of the dust to the dust outlet and then sent out of the dust box.

[0104] 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 when suctioning and a dust outlet when collecting dust. The dust inlet when suctioning and the dust outlet when collecting dust are provided as the same opening, thereby reducing the number of ports, allowing existing ports to be efficiently shared, and reducing the possibility of air leakage. A filter is provided on the second opening 3012. For specific structure and installation methods, refer 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 located approximately on the central axis of the automatic cleaning device in the forward and backward directions. With this design structure, when dust is sucked through the fan of the automatic cleaning device, the airflow path is linear, which prevents detouring airflow and improves the smoothness of the airflow path.

[0105] In some embodiments, the receiving cavity 200 includes a first cavity 201 and a second cavity 202 arranged adjacently 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, and the dust suction opening 203, the air outlet 208, the first opening 3011, and the second opening 3012 are all located approximately on the central axis of the automatic cleaning device in the front-to-back direction. During dust suction or collection, the airflow zigzags and does not pass through a duct or airway, thereby reducing fan power and suction loss, maximizing fan effectiveness, saving energy, and reducing noise.

[0106] In some embodiments, the mobile platform 100 includes a positioning element 1211 located approximately on the central axis of the mobile platform 100 in the forward-backward direction, and a cover 940 disposed over the positioning element 1211. A fan is disposed in the space below the second cavity 202, and the positioning element 1211, cover 940, fan, main brush module 153, dust suction port 203, air outlet 208, first opening 3011, and second opening 3012 are all located approximately on the central axis of the automatic cleaning device in the forward-backward direction. In related art, when a single air inlet is used, the intake airflow is not symmetrical, the dust inlet is usually offset, resulting in an unsightly appearance, and the inlet and outlet paths of the entire airway are not linear, resulting in airflow obstruction and loss, and affecting the layout of other devices. After the air inlet is added, the airway structure is located on the central axis, thereby avoiding the shortcomings of existing dust collection methods, such as low dust collection efficiency and residual dust. This overcomes the technical drawbacks of existing technologies, such as the offset airway, which causes losses in fan power and suction force due to the zigzag duct, while at the same time significantly improving the design appearance and component placement space. The port of the main brush module 153 is also located on the central axis, ensuring that the dust collection airway is not obstructed, reducing losses and improving efficiency.

[0107] According to a specific embodiment of the present disclosure, the present disclosure provides an automatic cleaning system including a dust collection station and an automatic cleaning device described in any one of the above items, 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.

[0108] 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.

[0109] 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 is connected to a port of the main brush module of the automatic cleaning device, and dust 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 to abut and seal the dust collection port 711 against the port of the main brush module of the automatic cleaning device and prevent dust leakage.

[0110] FIG. 24 is a schematic diagram of the scene 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 garbage in the dust box of the automatic cleaning device into the garbage bag of the dust collection station.

[0111] The present disclosure provides an automatic cleaning device and system, which has an automatic dust collection function, and which has two dampers asymmetrically installed in the dust box of the automatic cleaning device, so that the airflow entering the dust box forms a convection current, forming a vortex within the dust box, and smoothly sucking dust in the dust box into a dust collection station; and by arranging the main brush module, the dust suction port, the air outlet, the first opening, and the second opening approximately on the central axis of the automatic cleaning device in the front-to-rear direction, the speed of the airflow flowing through the dust box during dust collection can be further increased, improving dust collection efficiency and simultaneously allowing dust in the dust box to be easily sucked into the dust collection station during dust collection.

[0112] In the related art, an automatic cleaning device includes a positioning device, which includes a positioning element and a cover. Usually, the positioning element arranged in the automatic cleaning device has a fixed size, and the size of the positioning element is approximately matched to the assembly space. However, if the application device needs to reduce the volume of the positioning element, it needs to redevelop the mold or adjust the position of the equipment around the assembly space of the positioning element, which causes great inconvenience to the flexible application of the positioning element.

[0113] For this reason, the embodiments of the present disclosure provide an automatic cleaning device that assembles a miniaturized positioning element in the original assembly space, and the positioning device described in this embodiment includes, but is not limited to, a camera and a laser distance measuring device (LDS). For ease of understanding, the positioning device described in this embodiment is described as a laser distance measuring device. However, this embodiment makes the application of the positioning device more flexible by rationally configuring the structure and positional relationship of the assembly bracket, rotor, motor, cover, etc., and the same structure has the same technical effect, so the description of partial technical effects will be omitted here. 25 , the automatic cleaning device includes an assembly 800 mounted on a rack, an assembly structure 900, and a positioning element 1211, and the positioning element 1211 is assembled to the assembly 800 via the assembly structure 900. The assembly 800 is typically part of a rack and has one or more screw holes. The assembly structure 900 has one or more corresponding screw holes, and the positioning element 1211 is assembled to the assembly 800 via bolts. The assembly 800 is the location within the automatic cleaning device where the assembly structure 900 and the positioning element 1211 are assembled. Generally, once the design of each part of the automatic cleaning device is complete, their positions and sizes are fixed, and correspondingly, the spatial position of the spare assembly 800 is also fixed. As a result, if a smaller-sized positioning element of the automatic cleaning device needs to be replaced, it cannot be accommodated in the spare assembly 800. Therefore, the assembly structure and the structure of the positioning element of the automatic cleaning device according to the embodiment of the present disclosure are improved as follows:

[0114] As shown in FIG. 26, the assembly structure 900 includes an assembly bracket 910, and the positioning device includes a rotor 920, a motor 930, a cover 940, etc. The assembly bracket 910 is fixed to the assembly part 800 through screw holes around the bracket, the rotor 920 and the motor 930 are installed inside the assembly bracket 910, and the cover 940 is installed to cover the top of the rotor 920, performing shielding and protection functions. The rotor 920 protrudes from the top surface of the automatic cleaning device, and the rotor 920 continuously rotates and scans within a 360-degree range, thereby continuously detecting obstacles during the operation of the automatic cleaning device. As shown in FIG. 27, the assembly bracket 910 includes a rotor accommodating portion 911 and a motor accommodating portion 912, the rotor accommodating portion 911 includes a first arc-shaped sidewall 9111, which includes an arc-shaped sidewall of another curvature, where the arc-shaped sidewall is at least a portion of a circle, and as shown in FIG. 27, the first arc-shaped sidewall 9111 is a majority of the circular structure, for example, a portion within a range of 180 to 270 degrees, and the motor accommodating portion 912 includes a second arc-shaped sidewall 9121, which is a portion of the circular structure. The first arc-shaped side wall 9111 of the rotor accommodating section and the second arc-shaped side wall 9121 of the motor accommodating section are smoothly connected, and as shown in Figure 27, the rotor accommodating section 911 and the motor accommodating section 912 are divided at approximately MN into the rotor accommodating section 911 and the motor accommodating section 912, and the opening area formed by the first arc-shaped side wall 9111 is larger than the opening area formed by the second arc-shaped side wall 9121. The positioning element 1211 includes a rotor 920, and the rotation axis of the rotor 920 is positioned approximately at the geometric center of the rotor accommodating portion 911. If the first arc-shaped side wall 9111 is an arc-shaped side wall, the geometric center of the rotor accommodating portion 911 corresponds to the center of the circle on which the first arc-shaped side wall 9111 is located. If the first arc-shaped side wall 9111 is a combined structure of arcs with multiple different curvatures, the geometric center of the rotor accommodating portion 911 corresponds to the center of the circle on which the arc with the maximum arc degree is located, for example, at A shown in Figure 27.The rotor 920 is configured to transmit and / or receive detection signals, such as visible light and / or invisible light, while continuously rotating. The rotor 920 has a smaller diameter than the rotor of a conventional positioning element, i.e., a greater distance to the first arc-shaped side wall 9111 of the rotor housing. However, the rotor 920 is still assembled at the geometric center of the rotor housing 911 to ensure structural symmetry and stability after rotation. The positioning element 1211 includes a motor 930. The output shaft of the motor 930 is disposed at the junction between the rotor housing 911 and the motor housing 912, i.e., located approximately on the connecting line between the geometric center of the motor housing and the geometric center of the rotor housing. For example, it is located at B in FIG. 27 . Specifically, it is located approximately between the connecting line between the geometric center C of the motor housing and the geometric center A of the rotor housing, except for points A and C. That is, it is closer to the geometric center A of the rotor housing than the geometric center C of the motor housing. This allows the miniaturized positioning element motor to be closer to the rotor, and the internal housing structure of the assembly bracket can better accommodate the positioning element motor and rotor, improving stability and reducing the size of the transmission element, e.g., the belt, and reducing energy loss and material costs. In some embodiments, the communication portion is located approximately at the center of the smooth connection between the first arc-shaped sidewall 9111 and the second arc-shaped sidewall 9121, i.e., the MN connection line. If the second arc-shaped sidewall 9121 is an arc-shaped sidewall, the geometric center of the motor housing portion 912 corresponds to the center of the circle on which the second arc-shaped sidewall 9121 is located. If the second arc-shaped sidewall 9121 is a combined structure of multiple arc-shaped sides with different curvatures, the geometric center of the motor housing portion 912 corresponds to the center of the circle on which the arc with the largest arc degree is located, as shown in FIG. 27C. Motor 930 is configured to be connected to the rotor via a transmission structure 932, e.g., a belt, to provide driving force to the rotor. Here, the motor 930 drives the rotor 920 via the motor roller 931 and the transfer structure 932, and the transfer structure 932 may be a belt, a metal belt, an organic material belt, etc., and the rotation shaft of the motor 930 is hardwired to the motor roller 931, and the motor roller 931 rotates freely under the drive of the motor rotation shaft.

[0115] In some embodiments, the position determining device is a laser ranging device, wherein the position determining element is a laser ranging element that detects distance or position by transmitting and receiving laser signals while continuously rotating.

[0116] In some embodiments, as shown in FIG. 27, the motor accommodating portion 912 includes an opening 19122 located on the bottom surface 9124 of the motor accommodating portion 912 and configured to accommodate the motor 930, and a first support rib 9123 extending inward along the inner side of the motor accommodating portion side wall 9121 to the edge of the opening 19122, wherein the geometric center B of the opening 19122 is closer to the geometric center A of the rotor accommodating portion than the geometric center C of the motor accommodating portion, and wherein the geometric center B of the opening 19122 is located approximately at the center of the circle in which the arc of the opening 19122 is located, and the geometric center C of the motor accommodating portion is located approximately at the center of the circle in which the motor accommodating portion side wall 9121 is located. Compared to conventional motors, the mounting position is usually at the geometric center C of the motor housing. However, if the overall structure of the positioning element is made smaller and rotor 920 is still at the geometric center A of the rotor housing, transmission loss can be reduced, transmission efficiency can be improved, and stability during belt transmission can be improved. Assembling motor 930 closer to the rotor maintains a nearly constant rotational gap between motor 930 and rotor 920, maintaining significant transmission efficiency. This is suitable for smaller positioning elements, eliminating the need for separate molding and reducing costs. The closer the motor is to the rotor, the less transmission devices such as belts are needed, further reducing costs, while simultaneously reducing transmission resistance and improving transmission efficiency. In this case, a first support rib 9123 must be added to increase the stability and rigidity of assembly bracket 910. The longer the first support rib 9123, the greater the distance from the motor.

[0117] In some embodiments, as shown in FIG. 27, the rotor accommodating portion 911 includes an opening 29112 located on the bottom surface 9114 of the rotor accommodating portion 911 and configured to accommodate the rotor 920, and a second support rib 9113 extending inward along the inner side of the rotor accommodating portion side wall 9111 to the edge of the opening 29112, whereby the second support rib 9113 improves the stability and rigidity of the assembly bracket 910, and wherein the geometric center of the opening 29112 corresponds to the geometric center of the rotor accommodating portion 911 and is located approximately at the center of the circle on which the rotor accommodating portion side wall 9111 is located, thereby ensuring the symmetry of the structure and the stability of the rotor after rotation.

[0118] 27, the opening 2 communicates with the opening 1, and the area of ​​the opening 2 is larger than the area of ​​the opening 1. The opening 2 communicates with the opening 1 to reduce the machining process of the bracket structure, and the communicating structure allows the motor to drive the rotor to rotate through the transfer structure.

[0119] In some embodiments, as shown in FIG. 28, the positioning device further includes a cover 940 covering the top of the rotor 920, which can block stray light from entering the positioning device, block dust, impurities, etc. from entering the positioning device, and also shield the internal components of the positioning device for aesthetic purposes. After adding a pivot structure to the cover 940, it can avoid hanging obstacles. The cover 940 includes a circular top surface 941, a bottom circular ring 942, and a plurality of connecting members 943 connecting the circular top surface 941 and the bottom circular ring 942. In some embodiments, the bottom circular ring 942 includes a base plate extending horizontally from its bottom, the bottom circular ring 942 is fixedly connected to the base plate or is integrally formed therewith, and the base plate is pivotally connected to the cover 940 and the top surface of the moving platform. A first gap is formed between the bottom circular ring 942 and the outer circumferential surface of the rotor 920, and gaps are formed between the plurality of connecting members 943, and detection signals, such as visible light and / or invisible light, can be transmitted and / or received by rotation of the rotor. Furthermore, since the rotor structure described in this embodiment is a miniaturized rotor and the cover 940 corresponds to the size of the cover of a conventional positioning device, the first gap is larger than the conventional gap.

[0120] In some embodiments, to solve technical problems caused by a large first gap, such as the ingress of stray light, dust, impurities, and the exposure of internal components of the positioning device, the size of the cover as a whole may be reduced to reduce the distance of the first gap. For example, in some embodiments, the cover 940 includes a circular top surface 941, a bottom ring 942, and a plurality of connecting members 943 connecting the circular top surface 941 and the bottom ring 942. The bottom ring 942 includes a base plate extending horizontally from its bottom. The bottom ring 942 is fixedly connected to or integrally formed with the base plate. The base plate is used for pivotal connection between the cover 940 and the top surface of the moving platform. A second gap is formed between the bottom ring 942 and the outer circumferential surface of the rotor 920. The second gap is smaller than the first gap. The second gap allows the bottom ring 942 to be as close as possible to the outer circumferential surface of the rotor 920 without affecting the rotation of the rotor, and may be, for example, 1 to 5 mm.

[0121] As shown in Figures 29 to 31, in some embodiments, to solve the technical problem caused by the first gap being too large, the assembly structure 900 further includes an annular shielding member 950, which is tightly fitted to the inside of the bottom ring 942, and a second gap is formed between the annular shielding member 950 and the outer peripheral surface of the rotor 920, the second gap being smaller than the first gap, allowing the rotor to rotate flexibly, and the second gap allows the annular shielding member 950 to be as close as possible to the outer peripheral surface of the rotor 920 without affecting the rotation of the rotor, and the gap can be, for example, 1 to 5 mm.

[0122] 30 , the annular shielding member 950 has a width extending along a radial direction and a height extending along an axial direction, and the width of the annular shielding member is greater than the height. The width of the annular shielding member 950 extending along a radial direction is sufficient to block stray light caused by an excessively large size of the first gap. The height of the annular shielding member 950 extending along an axial direction can facilitate assembly of the annular shielding member 950 inside the bottom annular ring 942.

[0123] 30 , the annular shielding member 950 includes an insert member 951 that fits to the connecting member 943, and after the insert member 951 is inserted into the connecting member 943, the annular shielding member 950 fits tightly against the inside of the bottom ring 942, the insert member 951 is provided in a one-to-one correspondence with the connecting member 943, the third slot 9433 is provided below the connecting member 943, and the T-shaped protrusion 9512 is provided below the insert member 951. When the insert member 951 is inserted into the inner wall of the connecting member 943, the thickness of the connecting member 943 increases and the distance of the first gap decreases, thereby further reducing stray light entering the rotor 920.

[0124] In some embodiments, as shown in FIG. 29 , the inner wall of the connecting member 943 includes a first slot 9431, and the outer wall of the insert member 951 includes a cam beam 9511 fitted into the first slot 9431, and when the cam beam 9511 is inserted into the first slot 9431, the annular shielding member 950 fits tightly against the inside of the bottom annulus 942, and when the cam beam 9511 is inserted into the first slot 9431, the circumferential stability of the annular shielding member 950 is improved. In some embodiments, as shown in FIG. 29 , the bottom ring includes a second slot 9432 extending along the circumferential direction of the bottom surface of the bottom ring and a third slot 9433 on the inner surface of the bottom ring 942, and the second slot 9432 is connected to the third slot 9433. As shown in FIG. 31 , the annular shielding member 950 includes a T-shaped protrusion 9512 protruding outward along the outer wall of the annular shielding member 950. When the T-shaped protrusion 9512 is inserted into the third slot 9433, the annular shielding member 950 fits tightly against the inner surface of the bottom ring 942. When assembling the annular shielding member 950, the T-shaped protrusion 9512 is first inserted along the bottom of the second slot 9432 and then pushed upward to insert the T-shaped protrusion 9512 into the third slot 9433, further improving the stability of the annular shielding member 950 in the circumferential and radial directions.

[0125] 29 , the bottom ring 943 further includes a limiting groove 9434 on the inner surface of the bottom ring 943, the limiting groove 9434 being symmetrically arranged on both sides of the third slot 9433, the annular shielding member 950 including limiting protrusions 9513 on both sides of the T-shaped protrusion 9512, the annular shielding member 950 fitting tightly to the inner surface of the bottom ring 942, and the limiting protrusions 9513 fitting into the limiting groove 9434. The engagement of the limiting protrusions 9513 with the limiting groove 9434 further limits the position of the annular shielding member 950.

[0126] The embodiments of the present disclosure provide an automatic cleaning device, and in the positioning device, by using an assembly bracket with a corresponding structure, a positioning element smaller than a conventional positioning element can be assembled into an assembly part corresponding to the conventional size, which makes it convenient to change the size of the positioning element as needed.

[0127] In related art, the top of an automatic cleaning device is not completely closed, which can allow water to enter the device. For example, if a user accidentally spills water on the automatic cleaning device, water can enter the device through gaps in the top cover of the automatic cleaning device, such as gaps in the positioning device, and damage elements such as a circuit board, potentially leading to a malfunction of the automatic cleaning device. The present disclosure provides an automatic cleaning device, which includes a moving platform with a receiving cavity, a positioning device at least partially mounted in the receiving cavity, a circuit board mounted on the moving platform adjacent to the receiving cavity, and a water-blocking bracket mounted between the circuit board and the receiving cavity and preventing liquid from entering the circuit. Here, the positioning device includes a positioning element and a cover, and the positioning device includes an imaging device, a laser ranging device, etc. The embodiments of the present disclosure will be described specifically using a laser ranging device as an example, and the positioning element is a laser ranging unit.

[0128] Figure 32 is a schematic top view of a mobile platform body in a mobile platform provided by some embodiments of the present disclosure, Figure 33 is a schematic bottom view of a platform cover assembled to the top of the mobile platform body provided by some embodiments of the present disclosure, and Figure 34 is a schematic top view of a platform base plate assembled to the mobile platform body provided by some embodiments of the present disclosure.

[0129] The automatic cleaning device includes a moving platform 100, a positioning device 121, a circuit board 105, and a water-blocking bracket 104. The moving platform 100 includes a receiving cavity 1011, and at least a portion of the positioning device 121 is mounted in the receiving cavity. The circuit board 105 is mounted on the moving platform 100 to support various electronic components of the automatic cleaning device and is mounted adjacent to the receiving cavity 1011. The water-blocking bracket 104 is mounted between the circuit board 105 and the receiving cavity 1011 to prevent liquid from entering the circuit board 105 and damaging the electronic components on the circuit board 105.

[0130] Specifically, the mobile platform 100 includes a mobile platform body 101, a platform cover 102, and a platform base plate 103, and the structures of the platform cover 102 and the platform base plate 103 are adapted to the structure of the mobile platform body 101 and may be specifically configured according to the actual product. Here, the mobile platform body 101 drives the automatic cleaning device to move and perform various cleaning tasks, and the mobile platform body 101 is provided with an accommodating cavity 1011, which is used to accommodate at least a part of the structure of the positioning device 121.

[0131] The storage cavity 1011 is a hollow cavity, and a water barrier wall 10111 is provided in the hollow cavity to guide the liquid that has entered the storage cavity to the bottom of the storage cavity and prevent it from splashing. In some embodiments, the water barrier wall 10111 is a side wall of a part of the storage cavity 1011, as shown in Figure 35 below.

[0132] A drain hole 10112 is provided at the bottom of the storage cavity 1011, allowing liquid collected in the storage cavity to flow out of the storage cavity. In some embodiments, there are multiple drain holes 10112, each provided at a different position on the edge of the bottom of the storage cavity, and the water barrier wall 10111 forms a water circuit together with the bottom of the storage cavity, so that almost all of the liquid that enters the storage cavity flows into the drain hole 10112.

[0133] The moving platform body 101 further has a storage space, which is used to store the dust box 300 in the cleaning module 150 .

[0134] The platform cover 102 is the top of the automatic cleaning device and has an opening 1021, and in response to the platform cover 102 engaging with the mobile platform main body 101, the platform cover 102 substantially covers the position determination device 121, and some of the structure of the position determination device is exposed to the external environment through the opening 1021.

[0135] The platform cover 102 is further provided with a water-blocking rib 1022 on its side facing the mobile platform main body 101, protruding toward the mobile platform main body. When the platform cover 102 is engaged with the mobile platform main body 101, the water-blocking rib 1022 is located between the circuit board 105 and the receiving cavity 1011, and is located on the side of the water-blocking bracket 104 away from the circuit board 105. The water-blocking rib 1022 effectively guides the condensed water formed on the inner surface of the top casing after water vapor that may be generated in the automatic cleaning device rises and condenses, moving along the platform cover 102 toward the surface of the mobile platform main body, and flowing over the water-blocking bracket 104 from above, dripping onto the circuit board 105, and preventing damage to the electronic components on the circuit board 105.

[0136] The platform cover 102 further includes an opening 1023 configured to insert or remove a dust box 300 through the opening 1023, and the orthogonal projection of the opening 1023 on the moving platform is within the storage space. When the dust box is inserted into the storage space, the surface of the dust box away from the platform base plate is flush with the platform cover, i.e., the top surface of the dust box functions as part of the top surface of the automatic cleaning device. This eliminates the need for a top flap, simplifying the device structure and further improving the technical and aesthetic appearance of the automatic cleaning device.

[0137] The platform base plate 103 is disposed at the bottom of the moving platform body 101, facing the platform cover 102. A holding groove 1031 configured to collect liquid discharged from the drain hole 10112 is disposed on the platform base plate 103. The drain hole 10112 is orthogonally projected onto the platform base plate 103 and is located within the holding groove 1031, allowing liquid discharged from the drain hole 10112 to naturally fall into the holding groove 1031. A drain port 1032 is further disposed on a side wall of the holding groove 1031, and liquid in the holding groove 1031 is discharged through the drain port 1032, thereby accurately guiding the specific discharge direction of the liquid and avoiding interference with the cleaning task. In some embodiments, the size and number of the holding grooves 1031 are adapted to the positions and number of the drain holes 10112.

[0138] The platform base plate 103 further includes a third opening 1033 configured to expose at least a portion of a dry cleaning module of the automatic cleaning device and to communicate with the moving platform body 101. The third opening 1033 is located adjacent to the retaining groove 1031, and the drain port 1032 guides liquid in the retaining groove 1031 to flow out of the automatic cleaning device through the third opening 1033.

[0139] At least a portion of a water-blocking bracket 104 on the moving platform 100 is provided around the positioning device 121, and Fig. 35 is a schematic structural diagram of a water-blocking bracket provided by some embodiments of the present disclosure. As shown in Fig. 35, the water-blocking bracket 104 is provided between a circuit board 105 and the receiving cavity 1011 and is configured to prevent liquid from flowing into the circuit board 105. The circuit board 105 is a circuit element in the automatic cleaning device and is generally located on the side of the positioning device closer to the front part of the automatic cleaning device.

[0140] In the present disclosure, since external liquid, such as water, may enter the inside of the automatic cleaning device through a gap between the positioning device and the platform cover 102, the waterproof bracket 104 can prevent liquid from entering the circuit board from the location of the positioning device, and thus the waterproof bracket can be provided between the receiving cavity and the circuit board to enable waterproofing. In some embodiments, at least a portion of the waterproof bracket 104 is provided on an edge of the circuit board 105 away from the surface of the platform base plate 103.

[0141] Specifically, the waterproof bracket 104 includes a bottom wall 1041 provided at a first end of the circuit board close to the accommodating cavity and configured to extend along at least a portion of the edge of the first end, and a bracket side wall 1042 extending from the edge of the bottom wall close to the circuit board in a direction approximately perpendicular to the bottom wall, and the free end of the side wall remote from the bottom wall is farther from the bottom surface of the moving platform than the circuit board.

[0142] The bottom wall 1041 is a flat plate structure having a certain width, which is the length extending from the end of the bottom wall closest to the circuit board to the receiving cavity.

[0143] The bracket sidewalls 1042 include a first bracket sidewall 10421, a second bracket sidewall 10422 and a third bracket sidewall 10423 disposed opposite each other at both ends of the first bracket sidewall, a fourth bracket sidewall 10424 connected to one end of the second sidewall remote from the first bracket sidewall, and a fifth bracket sidewall 10425 connected to one end of the third sidewall remote from the first bracket sidewall. The first bracket sidewall 10421 is disposed at a first end of the circuit board close to the accommodating cavity, and the fourth and fifth sidewalls are located at both ends of the water-blocking bracket 104, respectively, and their ends are free ends. The fourth and fifth sidewalls are configured such that their orthogonal projections on the platform base plate 103 are within the accommodating cavity and guide liquid blocked by the water-blocking brackets to fall from the free ends into the accommodating cavity. In some embodiments, the first bracket sidewall, second bracket sidewall, and third bracket sidewall are all flat.

[0144] The water-blocking bracket 104 further includes a pivot shaft 1043 pivotally connected to the positioning device 121 and configured to move at least some elements of the positioning device relative to the water-blocking bracket 104. The pivot shaft 1043 is parallel to and spaced apart from the first bracket side wall 10421, and both ends of the pivot shaft 1043 are fixed to the second bracket side wall 10422 and the third bracket side wall 10423, respectively.

[0145] The waterproof bracket 104 further includes mounting holes 1044 , which are used to determine the position of the waterproof bracket 104 and secure the waterproof bracket to the moving platform 100 .

[0146] Fig. 36 is a schematic structural diagram of a position determination device in an automatic cleaning device provided according to some embodiments of the present disclosure, and Fig. 37 is a schematic diagram of an assembled structure of the position determination device and a mobile platform shown in Fig. 36. As shown in Figs. 36 and 37, at least a portion of the position determination device 121 is provided in an accommodating cavity of the mobile platform main body 101. Specifically, the position determination device 121 includes a position determination element 1211 and a cover 940. The position determination element 1211 is exposed to the outside through an opening 1201 in the platform cover, and the position determination element 1211 is rotatable relative to the mobile platform 100 and is used to measure the horizontal distance between the automatic cleaning device and an obstacle in the circumferential direction.

[0147] The cover 940 snaps onto the positioning element 1211 to protect the positioning element from damage. FIG. 38 is a schematic structural diagram of the cover in the positioning device shown in FIG. 36 , and FIG. 39 is a schematic structural diagram of the cover shown in FIG. 38 from another perspective. As shown in FIGS. 38 and 39 , the cover 940 specifically includes a base plate 1221 and an engaging cover 1222 protruding from the base plate. A liquid guide hole 1223 is provided at the boundary between the base plate 1221 and the engaging cover 1222. The number of liquid guide holes 1223 may be one or more. When there are multiple liquid guide holes 1223, they are spaced apart at the boundary. A portion of the liquid dripping onto the base plate 1221 enters the receiving cavity 1011 through the liquid guide hole 1223.

[0148] The base plate 1221 has a flat structure, and an opening 12210 is formed in the base plate 1221, and the engagement cover 1222 protrudes from the opening 12210 of the base plate toward a side away from the platform base plate 103 and is used to accommodate a positioning element 1211. A pivot structure 1224 is provided on a surface of one end of the base plate 1221 close to the platform base plate 103, and the pivot structure 1224 is fitted to the pivot shaft 1043, and the base plate 1221 is pivotally connected to the water-blocking bracket 104 via the pivot shaft 1043.

[0149] At least a portion of the base plate 1221 is disposed so as to overlap the bottom wall of the waterproof bracket 104, and a liquid conducting groove 1225 is provided between the edge of the base plate 1221 closest to the waterproof bracket 104 and the side wall of the waterproof bracket, and is configured to guide liquid that has dropped onto the base plate 1221 into the receiving cavity. That is, the liquid conducting groove 1225 collects and guides liquid that would otherwise flow into the circuit board so that it flows out.

[0150] In addition, in the present disclosure, a liquid conducting hole 1223 and a liquid conducting groove 1225 are provided, and when external liquid that enters through the gaps in the positioning device 121 falls onto the surface of the base plate 1221 and spreads and flows around, some of the liquid flows directly into the accommodating cavity through the liquid conducting hole 1223, and when some of the liquid flows to the circuit board, it flows directly into the liquid conducting groove 1225, and some of the liquid in the liquid conducting groove 1225 flows into the accommodating cavity along the first bracket side wall 10421, the third bracket side wall 10423, and the fifth bracket side wall 10425, and some of the liquid flows into the accommodating cavity along the first bracket side wall 10421, the second bracket side wall 10422, and the fourth bracket side wall 10424.

[0151] The engagement cover 1222 has a groove structure configured to accommodate at least a portion of the positioning element, and the specific shape of the engagement cover 1222 is adapted to the structure of the positioning element, and in some embodiments, the groove structure is a hollow cylinder. The groove structure is inverted over the opening 12210 of the base plate, and the edge of the groove away from the groove bottom is bonded to the edge of the opening of the base plate, specifically, either fixedly or detachably. A plurality of windows 12220 are provided around the sidewall of the groove structure, and the positioning element in the engagement cover 1222 emits laser light through the windows 12220 and receives the returned laser signal.

[0152] In response to the completion of the assembly of the moving platform 100, the positioning device 121, and the water-blocking bracket 104, liquid that has entered through the gap between the positioning device 121 and the opening of the platform cover 102 falls onto the surface of the base plate 1221 of the positioning device, and part of it flows into the receiving cavity through the liquid conducting hole 1223, and part of it flows into the receiving cavity through the liquid conducting groove 1225, and / or when water vapor is generated in the automatic cleaning device, the water vapor is concentrated on the inner surface of the platform cover 102 and Condensed water is formed, and the water-blocking rib 1022 guides the condensed water onto the surface of the base plate of the positioning device, and allows it to flow into the accommodating cavity through the liquid guide hole and liquid guide groove. The liquid collected in the accommodating cavity 1011 falls from the drain hole 10112 at the bottom of the accommodating cavity into the holding groove 1031 of the platform base plate 103, and the liquid in the holding groove flows out through the drain port 1032 and the third opening 1033 to the automatic cleaning device, thereby preventing damage to the circuit board caused by unintentional water splashing or condensation, and the automatic cleaning device has a waterproof function.

[0153] The automatic cleaning device provided by the present disclosure has a water-tight bracket between the circuit board and the receiving cavity, which prevents external liquid from entering the circuit board and damaging the circuit elements. It also eliminates the top flap design of the original automatic cleaning device, simplifies the structure of the device, and improves the technical and aesthetic appearance of the automatic cleaning device.

[0154] Another embodiment of the present disclosure provides an automatic cleaning device, and the difference between the automatic cleaning device described in this embodiment and the automatic cleaning device described in the above embodiment is that the automatic cleaning device described in this embodiment further includes a trigger system 180, which includes a trigger protrusion 181 and a trigger assembly 182. Figure 40 is a schematic diagram of an assembled structure of a moving platform, a positioning device, and a trigger assembly provided by some embodiments of the present disclosure, Figure 41 is a schematic diagram of a partial structure of the assembled structure shown in Figure 40, and Figure 42 is a schematic diagram of an exploded structure of the trigger assembly shown in Figure 41.

[0155] 39, the trigger protrusion 181 is provided on the bottom surface of the base plate 1221 away from the other end of the waterproof bracket 104. The trigger protrusion has a rigid structure and is configured to apply pressure to the trigger assembly, and is not limited to a specific shape.

[0156] 40 to 42 , the trigger assembly 182 is mounted on the moving platform 100. Specifically, the trigger assembly 182 is mounted in a receiving groove 1012 of the moving platform 100, which is mounted at the rear portion of the automatic cleaning device. Specifically, the trigger assembly 182 includes a trigger button 1821 and an elastic plate member 1822. The trigger button 1821 is configured to cause the automatic cleaning device to perform an anti-snag operation when pressed by the trigger protrusion. The elastic plate member 1822 is mounted in the receiving groove 1012 and is approximately parallel to and spaced apart from the bottom of the receiving groove. The elastic plate member may be a flat plate that bends under the action of an external force. In some embodiments, the elastic plate member 1822 is formed of a flexible material such as a carbon nanotube film, a polyester film, etc.

[0157] The elastic plate member 1822 includes a fixed end 18221 and a free end 18222, and in some embodiments, the elastic plate member 1822 has a "T"-shaped structure, the fixed end 18221 has an elongated structure, and the free end 18222 has a square structure, one end of the free end is connected to one end of the fixed end, the fixed end 18221 is fixedly connected to the side wall of the accommodating groove 1012, the elongated structure is engaged with the engaging hole 10121 of the side wall of the accommodating groove, and the free end is provided in a hanging position. The trigger button 1821 is provided on the elastic plate member and located at the free end 18222, and in response to the cover 940 being attached to the moving platform, the trigger button 1821 and the trigger protrusion 181 face each other and are provided at a certain distance from each other.

[0158] The trigger assembly 182 further includes a warp prevention fastener 1823 and a positioning post 1824, and the warp prevention fastener 1823 prevents the elastic plate member from being biased and warping away from the bottom of the accommodating groove 1012. The warp prevention fastener 1823 is located on a side wall of the accommodating groove 1012 away from the fixed end 18221 of the elastic plate member, and when the elastic plate member 1822 is not biased, the free end of the warp prevention fastener 1823 is as close as possible to the surface of the elastic plate member away from the bottom of the accommodating groove 1012.

[0159] One end of the positioning post 1824 is fixed to the bottom of the receiving groove 1012, extends upward along a direction perpendicular to the bottom of the receiving groove, and penetrates the elastic plate member to fix the elastic plate member.

[0160] When the automatic cleaning device is caught by an obstacle above during the cleaning process, the positioning device 121 pivots around the pivot shaft 1043, the base plate moves toward the trigger assembly 182, and the trigger protrusion 181 on the base plate triggers the trigger button 1821. When the trigger button 1821 is triggered, an anti-trap control signal is generated and sent to the control system 130. Thereafter, the control system 130 generates a corresponding control command to make the cleaning device perform an anti-trap operation, including but not limited to stopping, reversing, steering, etc. The trigger button 1821 has a certain pressing stroke, and normally, the movement amplitude generated by the base plate 1221 due to an obstacle above is equal to or less than the pressing stroke of the trigger button 1821, so that the anti-trap control signal can be safely generated. However, if the traveling speed of the cleaning apparatus is too fast and the height of the obstacle above is too low, the pivoting amplitude of the positioning device 121 may be too large, resulting in the amplitude of movement of the trigger protrusion 181 by the base plate 1221 exceeding the pressing stroke of the trigger button 1821 and damaging the trigger button. On the other hand, if the trigger button 1821 is provided on the free end 18222 of the elastic plate member 1822, the pressing force caused by excessive movement acts on the free end, causing the trigger button 1821 to continue moving downward together with the free end 18222. This buffering action prevents damage to the trigger button 1821, extends the service life of the anti-trap element, and improves the safety of the cleaning apparatus. At the same time, after the automatic cleaning device moves away from the obstacle above, the elastic plate member 1822 generates a reaction force that causes it to bend away from the bottom of the receiving groove, and under the blocking action of the anti-bending fastener 1823, the elastic plate member is finally parallel to the plane where the bottom of the receiving groove is located, ready to trigger the next possible anti-trap control signal. The installation of the elastic plate member 1822 ensures the operating safety of the trigger button 1821 and at the same time avoids the use of other additional elements such as springs, making the structure of the device more simplified, facilitating maintenance and element replacement, and reducing interference of surrounding metal parts with the positioning element.

[0161] The pressing structure on the cover of an existing automatic cleaning device is complex. For example, most existing cleaning device button structures involve attaching a soft rubber bracket to a hard rubber bracket, bonding the hard rubber cap to the soft rubber bracket, then attaching the soft rubber bracket to the top casing decorative cover of the device using double-sided adhesive tape, and then fastening the hard bracket to the top casing via a hook on the underside. This button assembly structure is complex, requires many parts, requires long assembly time, is cumbersome, and is expensive. Due to this multi-layer structure, when attaching the soft rubber bracket to the top casing decorative cover of the device, the soft rubber is prone to misalignment, making it difficult to attach and remove the button. Furthermore, the double-sided adhesive tape and the soft rubber are tightly bonded together during attachment and removal, which easily causes damage to the double-sided adhesive tape and soft rubber, making the button unreusable.

[0162] Therefore, the embodiments of the present disclosure provide an automatic cleaning device without a flip cover, simplifying unnecessary elements of the button assembly of the automatic cleaning device while increasing the space from below the button assembly to above the circuit board, so that more electronic components can be placed in the space, and at the same time increasing the elastic force of the button assembly, making it easier to press. 43 , according to a specific embodiment of the present disclosure, the present disclosure provides an automatic cleaning device, which includes a mobile platform 100 that automatically moves on an operating surface and includes a cover 1000 constituting at least a portion of the top surface of the mobile platform; and a button assembly 400 that is manually operated and pressed to control the operation of the automatic cleaning device, the button assembly 400 including a cap 410 and a bracket 420, assembled to the cover 1000, wherein the cover 1000 has a button mounting hole 1002, the button assembly 400 includes a pressing body 411 that is assembled to the button mounting hole 1002, and the top surface of the pressing body 411 is substantially flush with the top surface of the cover, so that a user can directly apply force to the pressing body during operation, eliminating the need for additional decorative components. In some embodiments, the top surface of the pressing body is slightly lower or higher than the top surface of the cover. This allows a user to easily identify the location of the button assembly by touch alone. Here, the button assembly 400 can be applied to the housing of any device that requires a mechanical button, including, but not limited to, a cleaning robot, a mopping robot, a sweeping / mopping robot, a handheld robot, a watering robot, etc. The button assembly may typically be provided on the top surface of the housing of the mechanical device or on the side of the housing of the mechanical device, but is not limited thereto. The housing of the mechanical device is typically made of, but is not limited to, a hard plastic, resin, metal, or alloy material.

[0163] 43 to 47, the button assembly 400 includes a cap 410 and a bracket 420. The cap 410 is typically made of a soft, opaque rubber material, providing sealing, waterproofing, and light-blocking properties during interference assembly. The bracket 420 is typically made of a hard rubber material, providing support during the cap assembly process and being fitted into a hard cover to secure the cap. As shown in FIG. 43, during assembly, the soft rubber cap is assembled to the cover from bottom to top, with at least the pressing body 411 assembled into the corresponding button mounting hole 1002. Then, the hard rubber bracket is assembled below the soft rubber cap, and the positioning post body 1001 on the cover 1000 and the positioning hole 425 on the bracket 420 secure the cap to the bracket 420, forming a button assembly. The two circular positioning holes 425 on the button bracket and the positioning post body 1001 with the fastening structure on the cover simultaneously perform a positioning function, and the cap 410 is assembled between the bracket 420 and the cover.

[0164] In some embodiments, as shown in FIG. 45 , the bracket 420 has a stepped structure 430 extending along the circumferential direction. When assembled, the stepped structure is a step that rises continuously from the outside to the inside or from the inside to the outside. Compared to a generally flat bracket, the raised portion of the stepped structure provides additional space and design flexibility for other components, allowing for more efficient use of the space above the bracket. Specifically, the orientation of the step can be designed according to the spatial requirements of other components. Alternatively, when assembled, the stepped structure is a step that rises continuously from the outside to the inside. This increases additional space, and the increased additional space in the middle ensures sufficient space below the corresponding pressing body for the pressing operation, contributing to the rationalization of the pressing stroke and elastic recovery, and improving user comfort. The steps of each layer of the stepped structure 430 extend circumferentially relative to the overall outer circumferential contour of the bracket 420 to form a closed structure, such as, but not limited to, a closed oval, circle, square, or rectangle. The stepped structure 430 has steps that rise continuously from the outside to the inside, forming a generally tapered stepped structure, extending upward from the outer step to the inner step. The specific number of steps is not limited, and may be, for example, 2 to 5 steps, e.g., 2 to 3 steps. As shown in Figures 44 and 45, the width and height of each step are not limited, and may be the same width and height, or may be steps of different widths and heights. The stepped structure 430 extending along the circumferential direction of the bracket 420 increases the protruding space below the bracket, and since the connected circuit board 105 is below the bracket, as shown in Figure 48, this protruding space provides greater component design convenience for the circuit board compared to a closed space, and the space occupied by the lower part of a conventional bracket can be utilized to accommodate more electronic components.In addition, the bracket 420 has a stepped structure 430 extending along the circumferential direction, which creates a larger protruding space below the bracket, increasing the elasticity of the rigid bracket. After the pressing force applied to the button assembly is transmitted to the rigid bracket, the bracket is more likely to elastically deform and recover after elastic deformation, giving the button assembly a better tactile feel and increasing the convenience of pressing the device.

[0165] 44 , the bracket 420 includes a bracket first sidewall 421 extending continuously along the circumferential direction of the outer edge of the bracket 420 and a bracket second sidewall 422 extending continuously along the circumferential direction of the inner edge of the bracket 420, wherein a first assembly portion 423 is formed between the bracket first sidewall 421 and the bracket second sidewall 422, and a second assembly portion 424 is formed within the bracket second sidewall 422. The bracket first sidewall 421 and the bracket second sidewall 422 extend circumferentially parallel to the overall outer peripheral contour of the bracket 420 to form a closed structure, such as, but not limited to, a closed oval, circle, square, or rectangle. The closed and extending bracket first sidewall 421 and bracket second sidewall 422 form the first assembly portion 423 and second assembly portion 424 of the receiving cap first protrusion 412 and the receiving cap second protrusion 413, respectively, and serve to fix and support the entire cap.

[0166] Specifically, in some embodiments, at least a portion of the step structure is located in the first assembly part 423, and another portion of the step structure is located in the second assembly part 424. For example, the first assembly part 423 has at least one step structure, and the second assembly part 424 has the highest step surface of the step structure. The bracket first side wall 421 and the bracket second side wall 422 also form a height structure substantially in accordance with the elevation of the step structure 430, for example, the bracket second side wall 422 is higher than the bracket first side wall 421, which can more stably support the cap and more completely seal it.

[0167] In some embodiments, both ends of the bracket 420 each include a positioning hole 425, and a positioning post body 1001 is provided at a position corresponding to the positioning hole 425 on the underside of the cover, and the positioning post body 1001 passes through the positioning hole 425 to fix the bracket 420. Optionally, the side wall of the positioning post body 1001 includes at least one protrusion, and the positioning post body 1001 is interference-assembled with the positioning hole 425, so that the bracket 420 is firmly fixed to the underside of the cover and at the same time provides an upward pressing force to fix the cap 410.

[0168] In some embodiments, the bracket 420 further includes a button plate 427 connected via at least one elastic arm 426, which is configured to move downward under the action of an external force to perform a pressing function, and the elastic arm 426 is configured to restore the button plate 427. As shown in FIG. 44 , the button plate 427 is typically located inside the bracket and includes a pair of symmetrically arranged button plates. The button plate 427 includes a button plate head 4271 that contacts the cap abutment portion 4171 and a button plate tail 4272 that presses against and contacts components on the circuit board 105. The width of the button plate head 4271 is typically greater than the width of the button plate tail 4272. A larger width of the button plate head 4271 makes it more susceptible to pressing forces, while a smaller width of the button plate tail 4272 allows for accurate contact and pressing of the component and prevents accidental pressing. The button plate 427 is connected to the inner edge of the bracket 420 via elongated elastic arms 426, and one or more elongated elastic arms 426 are arranged around the button plate 427 to provide the button plate 427 with sufficient pressing and restoring elastic force.

[0169] 46 and 47 , the cap 410 includes a pressing body 411 located approximately at the center of the cap 410, and a first protrusion 412 and a second protrusion 413 extending downward around the pressing body 411, the first protrusion 412 and the second protrusion 413 extending circumferentially parallel to the contour of the pressing body 411 to form a closed structure, wherein, when the cap 410 is assembled to the bracket 420, the first protrusion 412 and the second protrusion 413 fit into the first assembly part 423 and the second assembly part 424, respectively. To fit into the internal stepped structure of the first assembly part 423 and the second assembly part 424, the length of the downwardly extending first protrusion 412 is greater than the length of the downwardly extending second protrusion 413. The first protrusion 412 and the second protrusion 413 are respectively interference-assembled with the first assembly part 423 and the second assembly part 424, improving the stability and sealing performance of the cap assembly.

[0170] 46, a third protrusion 414 is provided on the upper surface of the cap 410, connecting the first protrusion 412 and the second protrusion 413 and extending upward around the pressing body 411. The third protrusion 414 is parallel to the contour of the pressing body 411 and extends circumferentially to form a closed structure. The cap 410 further includes a first groove 415 and a second groove 416 extending along both sides of the third protrusion 414, and the depth of the first groove 415 is greater than the depth of the second groove 416. 49 and 50, FIG. 50 is an enlarged bottom view of portion D of the cover in FIG. 49. The cover 1000 includes a button mounting hole 1002, and the pressing body 411 is assembled into the button mounting hole 1002. At this time, a downwardly extending edge 1004 is provided at the edge of the button mounting hole 1002, and the edge is inserted into the second groove 416 around the pressing body 411 by being inserted into the button mounting hole 1002 from bottom to top together with the pressing body 411. The edge 1004 forms one of the waterproof ribs of the cover 1000, and the side wall of the edge 1004 includes at least one bump. The pressing body 411 is assembled into the button mounting hole 1002 with interference, achieving a sealed connection and realizing waterproof and light-proof effects. Furthermore, in some embodiments, the cover 1000 includes a waterproof rib 1003 extending downward around the button mounting hole 1002. The waterproof rib 1003 is assembled to the first groove 415, and the side wall of the waterproof rib 1003 includes at least one bump, so that the waterproof rib 1003 is interference-assembled to the first groove 415. When the pressing body 411 is inserted into the button mounting hole 1002, the edge of the button mounting hole 1002 is inserted into the second groove 416 around the pressing body 411, and the waterproof rib 1003 is also interference-inserted into the first groove 415. The downward extending length of the waterproof rib 1003 is longer than the edge of the button mounting hole 1002, which further seals the pressing body 411 and the button mounting hole 1002, achieving good waterproof and light-proof effects.

[0171] 47 and 48, where FIG. 48 is a cross-sectional view taken along line AB in FIG. 1, two recesses 417 are provided in the second protrusion 413 at an interval, and the recesses 417 are configured to accommodate the button plate 427 in an assembled state. An abutment portion 4171 is provided at the top end of the recess 417, and after the cap and bracket are assembled, the button plate head 4271 is tightly abutted against the abutment portion 4171 and is susceptible to a pressing force.

[0172] 47 and 48, a downwardly extending light-blocking arm 418 is provided between the two spaced-apart recesses 417. The light-blocking arm 418 may be made of an opaque material or may be formed by applying an opaque material, and after components on the circuit board 105 are pressed by the button plates 427 on both sides, optical interference is formed between optical elements associated with the pressing operation, affecting the user's acquisition of optically presented information. The light-blocking arm 418 may be integrally molded with the cap, or may be later combined by processing such as bonding or engagement, but is not limited thereto.

[0173] The present disclosure provides an automatic cleaning device, in which a button assembly is assembled to a cover of the automatic cleaning device, the button assembly including a soft rubber cap and a hard rubber bracket, the cap being assembled to the bracket, the bracket having a stepped structure extending along the circumferential direction, the stepped structure being a step that rises continuously from the outside to the inside in the assembled state, the continuously rising stepped structure providing sufficient space below the button assembly to accommodate more components, and at the same time increasing the elastic force of the bracket, allowing the button assembly to recover more easily after being pressed, and increasing the settable length of the waterproof rib on the top cover, thereby improving the waterproof effect of the button assembly.
