Unless further limited, an element defined by the expression “includes…” does not exclude the presence of other identical elements in a product or apparatus containing such element.

[0027] The following describes in detail the selectable embodiments of this application with reference to the attached drawings.

[0028] Figures 1 and 2 are schematic diagrams of an automated cleaning device according to several embodiments. As shown in Figures 1 and 2, the automated cleaning device may be a vacuum cleaning robot, a mopping / brushing robot, a window climbing robot, etc., and consists of a mobile platform 100, a sensing system 120, a control system 130, a drive system 140, a cleaning module 150, an energy system 160, and a human-machine interactive system 170.

[0029] The mobile platform 100 is configured to automatically move its operating surface in the direction of a target. The operating surface may be a surface to be cleaned by an automatic cleaning device. In some embodiments, the automatic cleaning device may be a mopping robot, which works on a floor surface, the floor surface being the operating surface; the automatic cleaning device may be a window cleaning robot, which works on the outer surface of a building's glass, the outer surface of the glass being the operating surface; and the automatic cleaning device may be a pipe cleaning robot, which works on the inner surface of a pipe, the inner surface of the pipe being the operating surface. For purely illustrative purposes, this application describes an example in which the automatic cleaning device is a mopping robot.

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

[0031] The sensing system 120 includes a position determination device 121 located above the mobile platform 100, a buffer 122 located on the forward portion 111 of the mobile platform 100, a cliff sensor 123 located at the bottom of the mobile platform, and sensing devices such as an ultrasonic sensor (not shown), an infrared sensor (not shown), a magnetometer (not shown), an accelerometer (not shown), a gyroscope (not shown), and an odometer (not shown), which provide the control system 130 with various position information and movement status information of the equipment.

[0032] To more clearly describe the behavior of the automatic cleaning device, the following directions are defined. The automatic cleaning device can move on the floor surface by various combinations of movement along three mutually perpendicular axes: the lateral axis Y, the longitudinal axis X, and the central vertical axis Z, defined by the moving platform 100. The forward drive direction along the longitudinal axis X is denoted as "forward," and the rearward drive direction along the longitudinal axis X is denoted as "rearward." The lateral axis Y is substantially defined by the center point of the drive wheel assembly 141, and the axis center extends between the right and left wheels of the automatic cleaning device. Here, the automatic cleaning device can rotate around the Y axis. When the forward part of the automatic cleaning device tilts upward and the rearward part tilts downward, it is called "pitch up," and when the forward part of the automatic cleaning device tilts downward and the rearward part tilts upward, it is called "pitch down." Furthermore, the automatic cleaning device can rotate around the Z axis. In front of the automatic cleaning device, when the automatic cleaning device tilts to the right of the X axis, it is called "right turn," and when the automatic cleaning device tilts to the left of the X axis, it is called "left turn."

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

[0034] Specific types of position determination devices 121 include, but are not limited to, cameras and laser distance measuring devices (LDS).

[0035] Each assembly in the sensing system 120 may operate independently or may work together to more accurately achieve its purpose and function. The cliff sensor 123 and ultrasonic sensor can identify the surface to be cleaned, determine the physical characteristics of the surface to be cleaned, including the surface material and cleanliness, and make a more accurate determination in combination with a camera, laser rangefinder, etc.

[0036] For example, an ultrasonic sensor may be used to determine whether or not the surface to be cleaned is carpet, and if the ultrasonic sensor determines that the surface to be cleaned is made of carpet material, the control system 130 may control the automatic cleaning device to perform cleaning in carpet mode.

[0037] A buffer 122 is provided on the forward portion 111 of the mobile platform 100, and when the drive wheel assembly 141 propels the automatic cleaning device across the floor surface during the cleaning process, the buffer 122 may detect one or more events (or objects) in the path of the automatic cleaning device via a sensor system, such as an infrared sensor, and the automatic cleaning device may, by means of the buffer 122, detect the events (or objects), such as obstacles or walls, and control the drive wheel assembly 141 to move away from the obstacles in response to the events (or objects).

[0038] The control system 130 is located on a circuit board within the mobile platform 100 and includes a central processing unit that communicates with non-temporary memory such as a hard disk, flash memory, and random access memory, as well as an application processor. The application processor receives environmental information sensed by the multiple sensors from the sensing system 120, obstacle information fed back from a laser rangefinder, and other information. It uses a position determination algorithm, such as SLAM, to draw an instant map of the environment in which the automatic cleaning device is installed. Based on the environmental information and the environmental map, it autonomously determines a travel path and then controls operations such as forward, backward, and / or change of direction of the drive system 140 according to the autonomously determined travel path. Furthermore, the control system 130 can determine whether or not to activate the cleaning module 150 and perform a cleaning operation based on the environmental information and the environmental map.

[0039] In some embodiments, the control system 130 combines distance and speed information fed back from sensing devices such as the shock absorber 122, cliff sensor 123, ultrasonic sensor, infrared sensor, magnetometer, accelerometer, gyroscope, and odometer to comprehensively determine the current working state of the vacuum cleaner, such as crossing thresholds, riding on carpets, being located on cliffs, being stuck above or below, having a full dustbin, or being lifted. It then provides a specific next action strategy according to the different situations, ensuring that the automatic cleaning device better meets the owner's requirements and provides a better user experience. Furthermore, the control system can plan the most efficient and rational cleaning path and cleaning method according to the instant map information drawn by SLAM, thereby significantly improving the cleaning efficiency of the automatic cleaning device.

[0040] The drive system 140 can execute drive commands based on specific distance and angle information such as x, y, and θ components to operate the automatic cleaning device and make it travel across the floor surface. As shown in Figure 2, the drive system 140 includes a drive wheel assembly 141, and the drive system 140 can control the left and right wheels simultaneously. To control the operation of the device more precisely, it is preferable that the drive system 140 consists of a left drive wheel assembly and a right drive wheel assembly, respectively. The left and right drive wheel assemblies are arranged symmetrically along the transverse axis defined by the moving platform 100.

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

[0042] The energy system 160 includes rechargeable batteries such as nickel-metal hydride batteries and lithium batteries. The rechargeable batteries are connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery voltage drop monitoring circuit, and the charging control circuit, battery pack charging temperature detection circuit, and battery voltage drop monitoring circuit are connected to a microcontroller control circuit. The host computer is connected to the charging pile for charging via charging electrodes provided on the side or bottom of the main unit. There is a problem in that dust adheres to the exposed charging electrodes, and during the charging process, the cumulative effect of the charge causes the plastic body around the electrodes to melt and deform, and consequently the electrodes themselves deform, making it impossible to continue charging normally.

[0043] The man-machine interactive system 170 includes buttons on a host panel, which are available for the user to select functions, and may further include a display screen and / or indicator lights and / or a speaker, the display screen, indicator lights and speaker being able to show the user the current status of the device or function options, and may further include a mobile phone client program. In the case of a route navigation type automatic cleaning device, the mobile phone client can show the user a map of the environment in which the device is installed and the location of the device, providing the user with a richer and more user-friendly set of functions.

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

[0045] The dry cleaning module 151 includes a roller brush, dust box, fan, and air outlet. The roller brush, which interferes to some extent with the floor surface, sweeps debris from the floor surface in front of the dust intake port between the roller brush and the dust box, and the fan sucks the debris into the dust box via a gas with suction force that passes through the dust box. The dust removal capacity of a vacuum cleaner is indicated by the dust pickup efficiency (DPU), which is influenced by the roller brush structure and material, the airflow utilization rate of the duct consisting of the dust intake port, dust box, fan, air outlet and their connections, and the type and power of the fan, making it a complex system design issue. Compared to ordinary plug-in dust collectors, improved dust removal capacity is of great significance to energy-constrained automatic cleaning devices. This is because improved dust removal capacity directly and effectively reduces the energy required, meaning that a machine that can clean 80 square meters of floor space on a single charge can be improved to clean 180 square meters or more on a single charge. Furthermore, reducing the number of charging cycles significantly extends battery life, allowing users to reduce the frequency of battery replacement. More intuitive and importantly, the improved dust removal capability is the most obvious and significant user experience, allowing users to directly conclude whether the machine cleans or wipes cleanly. The dry cleaning module may further include side brushes 152 on the rotating shaft, which are at a certain angle to the floor surface and move debris to the roller brush area of ​​the cleaning module 150.

[0046] In some embodiments, the automatic cleaning device may further include a wet cleaning module configured to clean at least a portion of the operating surface using a wet cleaning method, wherein the wet cleaning module includes a water tank, a cleaning head, a drive unit, etc., wherein water from the water tank flows along a water circuit to the cleaning head, and the cleaning head cleans at least a portion of the operating surface under the drive of the drive unit.

[0047] The existing casing layout frame structure of automatic cleaning devices is complex, with a large number of parts, long assembly times, and cumbersome processes. Adding a top flap and flip mechanism to the automatic cleaning device, along with designing decorative top casing components on top of the top flap, increases costs. While the top casing components and top flap can serve functions such as concealing and protecting internal components, they complicate the overall structure of the machine, increase costs, and affect the design space for the dust box and other components beneath the top flap.

[0048] In this regard, embodiments of the present application provide an automatic cleaning device without a flip cover, which simplifies the design space of the dustbin and its housing cavity while simplifying unnecessary components of the automatic cleaning device, and the same technical effects are achieved with the same structure, although some technical effects are not repeated herein. Specifically, the present application provides an automatic cleaning device, as shown in Figures 3 to 5, which includes a moving platform 100 configured to automatically move an operating surface, and the moving platform 100 includes a housing cavity 200. In some embodiments, the housing cavity 200 is located towards the rear in the forward direction of the automatic cleaning device, and the housing cavity 200 includes a first cavity 201 and a second cavity 202. The automatic cleaning device further includes a dry cleaning module including a dust box 300, the dust box 300 being detachably assembled to the housing cavity 200, where the first cavity 201 and the second cavity 202 are arranged adjacently front to back 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 adjacently front to back in the forward direction of the automatic cleaning device, and the larger portion of the dust box in terms of volume and weight is located closer to the center of the automatic cleaning device, so that the dust box is more stably positioned in the housing cavity 200, the center of gravity of the entire cleaning device is more stable, and it is more stable during processes such as moving, turning, and crossing obstacles, and does not easily tip over. At the same time, the dust box housing and the dust box top cover are integrated into a single structure. The dust box top cover functions as part of the top surface of the mobile platform and is flush with the rest of the top surface of the mobile platform. This eliminates the flip cover structure of conventional cleaning devices. At the same time, the dust intake port, located approximately in the center of the bottom of the cleaning device, can be easily and directly aligned with the dust box. This allows dust to enter the dust box directly from the dust intake port, reducing the process by which dust enters the inside of the device and preventing dust contamination of the inside 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 in different structures, facilitating the integrated design of the dust box top cover. A dust intake port 203 is provided at the bottom of the front wall of the first cavity 201, and an air outlet 208 is provided on the rear wall of the connection point between the first cavity 201 and the second cavity 202. The air outlet 208 has a grille structure, and a fan is housed in the space below the second cavity 202, supported by a fan bracket. In some embodiments, the air outlet 208 constitutes part of the fan bracket, and an exhaust port 204 is provided on the rear wall of the moving platform 100. Under the suction force of the fan, dust enters the dust box 300 from the dust intake port 203, and the airflow is filtered by the dust box filter before being discharged from the exhaust port 204.

[0049] In some embodiments, the dust box 300 includes a containment section 301 and a top cover 302 located above the containment section 301, the top cover 302 being fixedly connected to the containment section 301. Methods of fixed connection include, but are not limited to, adhesive bonding, welding, integral molding, bolting, and fastening. The containment section 301 is used to contain dust sucked in through the dust intake port 203, and the appearance of the containment section 301 substantially matches that of the first cavity 201.

[0050] The roller brush, which makes some contact with the floor surface, sweeps up debris from the floor surface, and under the negative pressure airflow generated by the fan, it is wound in front of the dust collection port 203 between the roller brush and the dust box 300. Then, the airflow with suction force generated by the fan passes through the dust box 300 and sucks the debris into the dust box 300. The debris is then isolated inside the dust box 300 by the filter 500, and filtered air flows into the fan.

[0051] In some embodiments, the housing section 301 of the dust box 300 has a first opening 3011 on the front side of the dust box 300, which is aligned with the dust collection port 203, and the housing section 301 has a second opening 3012 on the rear side of the dust box, and the filter 500 is provided in the second opening 3012, which is connected to the air outlet 208. The filter 500 and the box body of the dust box 300 are detachably connected, making it easy to attach, detach, and clean the filter. Here, the front side refers to one side in the X direction along the forward direction of the automatic cleaning device after the dust box 300 has been assembled in the housing cavity 200, and the rear side refers to the side in the X direction opposite to the forward direction of the automatic cleaning device.

[0052] In some embodiments, the top cover 302 includes a first portion 3021 that covers the housing 301 and a second portion 3022 that protrudes from the housing 301 and extends outward. When the dustbin 300 is assembled into the housing cavity 200, the housing 301 and the first portion 3021 of the top cover 302 are housed in the first cavity 201, and the second portion 3022 of the top cover 302 is housed in the second cavity 202. The top cover 302 substantially matches the top portion of the first cavity 201 and the structure of the second cavity 202, thereby stably mounting the dust box 300 within the housing cavity 200 and preventing the dust box from shaking due to vibrations during the operation of the automatic cleaning device. At the same time, the top cover of the dust box can just cover the housing and fan positions, and the upper surface of the dust box top cover becomes nearly horizontal with the upper surface of the moving platform, ensuring the flatness of the outer surface of the automatic cleaning device, improving the overall coordination of the appearance, providing more spatial options for the design of each component including the housing on the lower surface of the top cover, making it convenient to position different components, improving the volume selectivity of the dust box, allowing specific sizes to be set as needed, and reducing molding costs without affecting the overall opening size of the housing cavity.

[0053] In some embodiments, the first portion 3021 of the top cover 302 includes a marginal portion 30211 that protrudes outward from the contour of the edge of the housing. The housing cavity 200 includes a stepped portion 205 that extends around the apex edge of the housing cavity, and the stepped portion 205 is configured to accommodate at least a portion of the marginal portion 30211 and at least a portion of the outer edge of the second portion 3022, so that the top surface of the top cover is substantially coplanar with the top surface of the moving platform. The housing cavity 200 includes a stepped portion 205 that extends around the apex edge of the housing cavity, and is capable of receiving the entire edge of the top cover 302, so that the top cover 302 is housed in the housing cavity 200 in a substantially gapless manner, so that foreign matter can be prevented from falling directly into the gaps of the edge of the dust box and getting caught in the dust box, while at the same time ensuring the appearance of the top cover as the top surface of the automatic cleaning device.

[0054] In some embodiments, a support structure 3023 is provided below the second portion 3022 of the top cover 302, configured to support the second portion 3022 of the top cover. In some embodiments, the support structure 3023 is integrally molded with at least a portion of the housing 301, thereby increasing the support force of the support structure 3023 on the second portion 3022 of the top cover 302 and effectively preventing damage thereto. The support structure 3023 includes, but is not limited to, arc-shaped structures and linear structures. For example, the support structure 3023 is two arc-shaped structures provided symmetrically, substantially coinciding with the outer edge contour of the second portion 3022 of the top cover 302.

[0055] In some embodiments, a groove 2021 is provided on the lower surface of the second cavity 202, the groove 2021 substantially coincides with the contour of the support structure 3023, and when the second portion 3022 of the top cover is housed in the second cavity 202, the support structure 3023 is housed in the groove 2021, and the upper surface of the top cover 302 becomes substantially horizontal.

[0056] In some embodiments, the top cover 302 is provided symmetrically along the central axis of the automatic cleaning device in the forward direction. In some embodiments, as shown in Figures 6A to 6H, the shape of the top cover is at least one of the following or a combination thereof: D-shaped, rectangular, square, circular, elliptical, triangular, quadrilateral, pentagonal, hexagonal, heptagonal, or octagonal. Symmetrical installation allows the appearance of the device to be maintained without being covered by an outer cover and is also convenient for attaching and detaching the dust box.

[0057] In some embodiments, as shown in Figure 8, the first cavity 201 includes a first locking member 701; as shown in Figure 10, the second cavity 202 includes a second locking member 72; as shown in Figures 5 and 7, the first portion 3021 of the top cover includes a first locking member 601; and as shown in Figure 9A, the second portion 3022 of the top cover includes a second locking member 602, with the first locking member 601 locking in cooperation with the first locking member 701 and the second locking member 602 locking in cooperation with the second locking member 72.

[0058] The above embodiment relates to a dust box for an automatic cleaning device and its mounting structure, wherein a housing cavity is provided on the rear side in the forward direction of the automatic cleaning device, and the housing cavity includes a first cavity and a second cavity, the depth of the first cavity being greater than the depth of the second cavity. After the dust box is incorporated into the housing cavity, the upper surface of the dust box top cover is substantially coplanar with the upper surface of the moving platform, thus simplifying the top surface structure of the automatic cleaning device, reducing production costs, and simultaneously increasing the design space of the housing cavity.

[0059] Existing automatic cleaning devices are equipped with pop-up and non-pop-up dustbins, and pop-up dustbins have top flaps and flip mechanisms. When attaching or detaching the dustbin, it is necessary to open the top flap and press the dustbin to pop it up. In this embodiment, a complex dustbin pop-up mechanism is required, which includes multiple parts such as springs. Repeated use of the springs reduces their elasticity, preventing the dustbin from popping up smoothly. Furthermore, many other parts may prevent the dustbin from popping up properly, negatively impacting usability. Non-pop-up dustbins almost always employ a complex locking structure, and the spring assembly within it is prone to breakage due to aging. The pressing member does not feel comfortable to the finger when operating it, resulting in a poor overall user experience.

[0060] In this regard, the embodiment of the present application provides an automatic cleaning device without a flip cover, simplifying unnecessary elements of the automatic cleaning device while facilitating the smooth removal of the dust box. This embodiment briefly describes some structural features compared to the above embodiment, but the same structure has similar technical effects, and some technical effects are not repeated herein. Specifically, as shown in Figures 1 to 5 and Figure 7, the automatic cleaning device comprises a moving platform 100 configured to move automatically on an operating surface and including a housing cavity 200 located at the rear in the forward direction, and a cleaning module including a dust box 300, the dust box 300 being detachably assembled to the housing cavity 200, and the dust box including a housing section 301, a top cover 302 located above the housing section, and a locking mechanism. The locking mechanism includes a first locking mechanism 610 substantially located on the central axis of the top cover, 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 being located within the first grommet recess 603, and the first locking member 601 being elastically movable relative to the first grommet recess 603 under external force. The first grommet recess 603 is a recess formed downward along the edge of a first portion of the top cover, the first grommet recess 603 provides sufficient depth in the Z direction, the height of the first locking member 601 is lower than the surface of the top cover, the first grommet recess 603 provides sufficient elastic space in the X direction, and provides sufficient working space for the first locking member 601 to elastically move inward.

[0061] In some embodiments, the first locking member 601 includes a first elastic arm 6011, a first grommet portion 6012, and a first buckle portion 6013. Here, the first elastic arm 6011 extends upward from the bottom of the first grommet recess 603. The first grommet portion 6012 is provided at an end portion that extends above the first elastic arm 6011. The first buckle portion 6013 extends along the lateral direction of the first elastic arm 6011. For material reduction and increased elasticity, the first elastic arm 6011 is generally in a substantially "U" shape as a whole, and this shape structure is not limited. The first grommet portion 6012 is provided above the first elastic arm 6011 in the lateral direction. 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 substantially flush with the top cover. The grommet surface may be in an arc-shaped structure, that is, the projection onto the horizontal plane is arc-shaped. The grommet surface facilitates the reception of manual operation and is more suitable for receiving force ergonomically by conforming to the shape of the finger. In some embodiments, the first buckle portion 6013 is a pair of sheet structures symmetrically provided along both sides of the first elastic arm 6011. To facilitate the insertion of the first locking member 701, the width of the sheet structure decreases from the root portion to the free end portion. The first elastic arm 6011 can be formed from a general elastic material as a whole, such as plastic or organic elastic material.

[0062] In some embodiments, as shown in FIG. 8, FIG. 8 is an enlarged schematic view of the first locking member 701 at A in FIG. 3A. The first locking member 701 is provided at a location approximately corresponding to the first locking member 601 on the inner wall of the accommodation cavity 200. The first locking member 601 is locked in cooperation with the first locking member 701. In some embodiments, the first locking member 701 is a pair of through holes, and the free end portion of the sheet structure is inserted into the through holes and locked.

[0063] In some embodiments, a first recess 206 is provided in the inner wall of the housing cavity at a location approximately 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 enters through the first recess 206 and applies force to pull the first locking member 601 out of the through hole. The cooperation of the first recess 206 and the first grommet recess 603 makes finger access easier and more convenient.

[0064] In some embodiments, as shown in FIG. 9A, the locking mechanism further includes a second locking mechanism 620. The second locking mechanism 620 includes a second grommet recess 605 and a second locking member 602. The second grommet recess 605 is formed with an inner notch, such as an arcuate or square notch, along approximately the midline position of the second portion 3022 of the top cover, making it easy for a finger to reach for a snap operation. The second locking member 602 is located below the second grommet recess 605. The second grommet recess 605 provides sufficient space for controlling the second locking member 602 by a finger, and the second locking member 602 elastically moves inward under an external force. Specifically, the second locking member 602 includes a second elastic arm 6021, a second grommet portion 6022, and a second buckle portion 6023. Here, the second elastic arm 6021 is located below the second grommet recess 605, and the second elastic arm 6021 includes two symmetric parts. Each second elastic arm 6021 first extends along the opening direction of the second grommet recess 605, then extends along the direction of the edge of the top cover, and then extends along the direction of the edge of the second grommet recess 605. Here, the opening direction of the second grommet recess 605 is the A direction from the center of the top cover outward as shown in FIG. 9A, which is also the backward direction of the dust box top cover in this embodiment. The two parts of the second elastic arm 6021 are symmetrically connected and provided in approximately a "Z" shape structure. The second grommet portion 6022 is connected to the two symmetrically provided parts of the second elastic arm 6021, and the second grommet portion 6022 is provided above the two second elastic arms. FIG. 9C is an enlarged view of the second grommet portion at C in FIG. 9B. As shown in FIGS. 9B and 9C, a bottom surface 60221 that substantially protrudes outward and a grommet surface 60222 that extends upward along the bottom surface are provided at the bottom of the second grommet portion 6022. The grommet surface extends to a position substantially flush with the top cover. The grommet surface may have an arcuate structure, which facilitates receiving a manual operation and makes it easy for a finger to apply a force.In some embodiments, the second grommet portion 6022 is integrally molded with a symmetrically arranged second elastic arm 6021, and the second buckle portion 6023 is provided on the laterally extended portion of the second elastic arm. The second buckle portion 6023 is provided symmetrically along both sides of a pair of the second elastic arms 6021 and is, for example, a projection or sheet structure extending along direction A, and in some embodiments, each of the second buckle portion 6023 has a groove extending inward from the end of the second buckle portion 6023, the groove preventing the entire second buckle portion from becoming too deformed after being molded and cooled, making it difficult to snap. In some embodiments, the second locking member 602 further includes a symmetrically arranged connecting member 6024, the connecting member 6024 being substantially planar, one end of the second elastic arm 6021 being connected to one face of the connecting member 6024, and the other face of the connecting member 6024 being connected to and fixed to the end face of a support structure. The second grommet portion 6022 is exposed from the second grommet recess 605 in the X direction. When unlocking, a finger reaches the second grommet recess 605 and presses the second grommet portion 6022, applying force inward along the X axis to the dust box and elastically contracting the second buckle portion 6023 inward. The second buckle portion 6023 then pops up from the bottom of the second locking member 702, achieving unlocking. The second elastic arm 6021 is generally formed as a whole from an elastic material such as plastic or an organic elastic material.

[0065] In some embodiments, as shown in Figure 10, which is an enlarged view of the second locking member 702 at location B in Figure 3B, the second locking member 702 is provided at a location on the inner wall of the housing cavity 200 that roughly corresponds to the second locking member 602, and the second locking member 602 is locked in cooperation with the second locking member 702. The second locking member 702 is a pair of projections, and the second buckle portion 602 extends to the bottom of the second locking member 702 to achieve locking. The projections may be flat, cylindrical, rectangular, etc., and are not limited thereto, as long as they can engage with the second buckle portion.

[0066] In some embodiments, a second recess 207 is provided on the lower surface of the second cavity 202 at a location approximately corresponding to the second grommet recess 605, and the pair of protrusions are provided on the rear wall of the second cavity 202 at the same height and located above the second recess 207. The second recess 207 is configured to accommodate the dust box 300 while avoiding the second locking member 602 when the dust box 300 is placed in the housing cavity 200, so that the entire dust box can be well positioned in the housing cavity 200.

[0067] In some embodiments, the top cover includes a first portion that covers the housing and a second portion that protrudes from the housing and extends outward, with the second grommet recess 605 and the second locking member 602 located in the second portion of the top cover. Below the second portion of the top cover, a support structure 3023 is provided, configured to support the second portion of the top cover, and the second locking member 602 is provided on the support structure 3023. As shown in Figure 4, the symmetrically arranged 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 structures 3023, sufficient elastic space is provided to respond to applied inward forces.

[0068] In the dustbin lock structure described in the above embodiment, the lock structure is provided symmetrically in the front-to-back direction of the dustbin top cover, and unlocking can be achieved by applying force to the two elastic structures on the front and rear of the dustbin with one hand. This prevents one side from being unlocked and the other 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 an elastic arm with an elastic material, thus avoiding the risk of damage to complex unlocking devices such as springs.

[0069] In some embodiments, as shown in Figure 4, the second locking mechanism 620 includes at least one first magnetic attraction module 604, the first magnetic attraction module 604 being located between the second portion of the top cover and the support structure. As shown in Figure 3A, the housing cavity includes at least one second magnetic attraction module 606 configured to work in conjunction with the first magnetic attraction module 604 to attract and lock. During use, pressing the first locking member 601 and the second grommet recess 605 by hand can retract the first locking member 601 corresponding to the dustbin, place the dustbin into the housing cavity, and when released, the first buckle portion 6013 on the first locking member 601 automatically pops up and inserts into the first locking member 701, the first magnetic attraction module 604 is attracted to the second magnetic attraction module 606, and the dustbin is locked. The locking structure is simple and easy to operate and convenient for achieving dustbin locking.

[0070] In some embodiments, the second locking mechanism 620 described above may include a second grommet recess 605 and a second locking member 602, or it may include a first magnetic attraction module 604, or it may include both, and is not limited thereto.

[0071] Existing automatic cleaning devices require dustbins to have replaceable dustbin filters. Conventional filters generally consist of a rigid frame made of plastic or metal, with cascaded filter media placed inside the frame. The frame and the area around the filter media are connected and sealed with dot adhesive, and then sealing strips are attached to the frame to seal the gap between the filter and the dustbin. Consequently, the structure of conventional dustbin filters is complex, the filter installation process is cumbersome, resulting in wasted labor and cost. Furthermore, the sealing adhesives are neither economical nor environmentally friendly.

[0072] In this regard, embodiments of the present application provide an automatic cleaning device configured to move automatically on an operating surface and comprising a moving platform including a housing cavity and a cleaning module including a dust box, wherein the dust box is detachably attached to the housing cavity and the dust box includes a dust box filter. The dust box filter is applied to the dust box of the automatic cleaning device, the assembly process of the dust box filter is simplified, and this embodiment simplifies some structural features compared to the above embodiment, the same structure has similar technical effects, and some technical effects are omitted here. As shown in Figures 11 and 12, the dust box filter 500 comprises a soft rubber frame 501 and a filter medium 502, wherein the soft rubber frame includes at least one soft rubber projection for sealing the assembly gap with the dust box during the assembly process, the filter medium 502 is sleeved within the soft rubber frame 501, where the soft rubber frame 501 is detachably connected to the filter medium 502. In some embodiments, the process of irremovably connecting the soft rubber frame 501 and the filter material 502 includes an overmolding injection process, in which the filter material is pre-sleeved within the frame, and then a rubber sleeve is further sleeved over the sleeved frame combination, thereby integrally forming a plurality of desired sealing protrusions. Alternatively, a two-shot injection molding process may be used, in which the hard rubber frame body is first injected, the filter material is sleeved within the frame body, and then the soft rubber is injected to form the inner and outer sealing protrusions.

[0073] The soft rubber frame 501 may have a rectangular, square, elliptical, circular, polygonal, or other structure, and is not limited to this structure. In some embodiments, as shown in Figures 11 and 12, the soft rubber frame 501 has a rectangular structure, and the rectangular soft rubber frame includes two opposing first side walls 50111 and two second side walls 50113. The soft rubber protrusions include a first protrusion 5011 distributed on the outer circumferential surface of one of the first side walls 50111 and a second protrusion 5015 distributed on the outer circumferential surface of the other first side wall 50111, and a pair of first side walls 50111 and a pair of second side walls 50113 are surrounded by a rectangular structural frame, and the filter material is sleeved within the rectangular structural frame.

[0074] In some embodiments, the first projection 5011 and the second projection 5015 are a continuous projection structure, for example, extending continuously from one end to the other of the outer circumferential surface of the first side wall 50111. Since the first projection 5011 and the second projection 5015 are made of soft rubber, when the dust box filter is assembled into the dust box, the first projection 5011 and the second projection 5015 are pressed together to directly seal 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 sealed by making sufficient contact with the inner wall that extends substantially horizontally. This replaces the prior art in which the dust box filter is sealed via a sealing strip after it has been assembled into the dust box.

[0075] In some embodiments, as shown in Figure 14, at least one of the first and second projections is an undercut structure, which is configured to seal the assembly gap between the soft rubber frame and the dust box while simultaneously preventing the dust box filter from falling out of the dust box. For example, the undercut structure is an arc-shaped structure, which is inclined toward the side opposite to the assembly direction of the dust box filter. The undercut structure is convenient for the dust box filter to extend into the dust box assembly opening with friction during the assembly process, inclined toward the opposite side of the assembly direction, and then pressed and sealed between the dust box filter and the dust box.

[0076] In some embodiments, the second side wall of the soft rubber structure further includes at least one third projection 5012, the third projection 5012 distributed on the outer circumferential surface of at least one second side wall 50113 of the frame structure. The third projection 5012 may be a dispersed plurality of projection structures. In one embodiment, the third projection 5012 is distributed on the outer circumferential surfaces of two second side walls 50113 of the frame structure, and when the dust box filter is assembled in the dust box, the third projection 5012 on the outer circumferential surface of one second side wall 50113 of the frame structure has a slightly longer structure, extends into a recess in the dust box side wall and functions as a fastener, preventing the dust box filter from falling off. At the same time, when assembling the dust box filter, the slightly longer third projection 5012 is first inserted into the recess in the dust box side wall, rotated around the third projection 5012, and then the other side of the dust box filter is attached to the dust box. The third projections 5012 distributed on the outer circumferential surface of another second side wall 50113 of the frame structure have a smoother structure, and when the dust box filter is assembled to the dust box, the third projections 5012 on that side are interlocked and locked to the dust box side wall elastic structure 5013, preventing the dust box filter from falling out. Here, the elastic structure 5013 is substantially an S structure and includes an inner recess that accommodates the third projections 5012 and an outer protrusion that is locked to the third projections 5012, the outer protrusion being able to move elastically under external force and be locked to the third projections 5012, as shown in Figure 15, which is a mounting structure diagram when viewing the dust box filter from the bottom end of the dust box. In some embodiments, as shown in Figures 13A and 13B, the soft rubber frame has a first rib position 510, which is provided on the outer circumferential surface of the second side wall, and is configured to prevent assembly defects such as the dust box filter being installed too deeply or too shallowly in the dust box. During the process of installing the dust box filter in the dust box, after being assembled in a predetermined position, the first rib position 510 abuts against a cushion position 5014 provided at a corresponding position on the dust box side frame, preventing further inward stretching of the filter and preventing the dust box filter from being installed too deeply in the dust box.At the same time, during the assembly process, as shown in Figure 15, if the first rib position 510 is not in contact with the pillow position 5014 of the dust box side frame, it is considered that the assembly is not in the predetermined position, thus preventing the dust box filter from being installed too shallowly in the dust box.

[0077] In some embodiments, as shown in Figures 13A and 13B, the soft rubber frame further includes an anti-mis-installation projection 509, which is provided on the outer circumferential surface of the second side wall and configured to prevent the dust box filter from being installed in the wrong direction. A recess is provided in the dust box at a position corresponding to the anti-mis-installation projection 509, and when the dust box filter is installed correctly, the anti-mis-installation projection 509 enters the recess and the dust box filter is assembled correctly. If the dust box filter is installed in the wrong direction, the anti-mis-installation projection 509 will not assemble the dust box filter because there is no recess on the other side of the dust box, thus serving to prevent mis-installation by drawing attention to the fact that the dust box filter is installed in the wrong direction.

[0078] In some embodiments, as shown in Figures 3A and 3B, the housing cavity 200 includes a first cavity 201 and a second cavity 202, which are arranged sequentially adjacent to each other in the forward direction of the automatic cleaning device, with the depth of the first cavity 201 being greater than the depth of the second cavity 202. A dust intake port 203 is provided at the bottom of the front wall of the first cavity 201, an air outlet 208 is provided on the rear wall of the connection point between the first cavity 201 and the second cavity 202, a fan is housed in the space below the second cavity 202, and an exhaust port 204 is provided on the rear wall of the moving platform 100. Under the suction force of the fan, dust enters the dust box 300 from the dust intake port 203, the airflow is filtered by the dust box filter, and then discharged from the exhaust port 204. Here, a grille structure is provided at the air outlet 208.

[0079] As shown in Figures 11 and 12, the flexible rubber frame further includes an inner sealing lip 507 and an outer sealing lip 506. The inner sealing lip 507 is provided on the first end face 50116 of the flexible rubber frame 501 around the filter media 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 of the second opening closer to the inner wall of the dust box, is substantially planar in structure, and is assembled to the flexible rubber frame by contacting the first end face 50116 of the flexible rubber frame 501. The outer sealing lip 506 is provided on the second end face 50115 of the flexible rubber frame 501 around the filter media 502 and is configured to seal the dust box filter and the edge of the air outlet 208 of the housing cavity 200. The inner sealing lip 507 and the outer sealing lip 506 are positioned higher than the first end face 50116 or the second end face 50115, and after being assembled in place, the inner sealing lip 507 is pressed between the assembly surfaces of the dust box filter and the dust box. Because the inner sealing lip 507 is made of a flexible material, under the action of the pressing force it seals the assembly surfaces of the dust box filter and the dust box, and when the dust box is assembled into the automatic cleaning device, the outer sealing lip 506 of the dust box filter is pressed between the dust box filter and the outside of the grille of the air outlet 208 of the housing cavity 200, sealing the assembly surfaces of the dust box filter and the fan bracket. As shown in Figures 3A and 3B, the side wall connecting the first cavity 201 and the second cavity 202 constitutes the assembly surface of the fan bracket, the fan is located below the second cavity 202, and the grille-type air outlet 208 is located on the side wall connecting the first cavity 201 and the second cavity 202. The inner sealing lip 507 and outer sealing lip 506 provided on the soft rubber frame 501 enable a sealed fit between the inner end surface of the dust box filter 500 and the dust box air outlet assembly surface, and a sealed fit between the outer end surface of the dust box filter 500 and the outer surface of the grille of the air outlet of the housing cavity 200.In the dust box filter, the conventional cumbersome step of adding sealing strips to the inside and outside to meet the airflow sealing requirements is eliminated. The soft rubber frame 501 acts as a carrier and includes an inner sealing lip 507 and an outer sealing lip 506, which are also somewhat flexible, as part of the sealing structure. This results in tighter contact, sealing, and fitting, a better fit, a stronger sealing effect, and ensures the airtightness of the entire airflow path, thus better protecting the functions of the cleaning device, such as dust collection and dust discharge, under negative pressure.

[0080] In some embodiments, as shown in Figures 11 and 12, the soft rubber frame further includes a stepped surface 503, the stepped surface 503 extending outward along the second end face 50115 of the soft rubber frame 501, and the stepped surface 503 and the side wall of the soft rubber frame 501 form a stepped structure, which prevents the dust box filter from being inserted too deeply into the dust box. During the assembly process, as shown in Figure 14, when the dust box filter enters the dust box assembly opening, the stepped surface 503 abuts against the outer edge of the dust box assembly and locks into the outer edge of the dust box, preventing the dust box filter from being inserted too deeply into the dust box.

[0081] In some embodiments, as shown in Figure 11, the soft rubber frame further includes a magnetic device mounting hole 504, which is provided on the second end face 50115 of the soft rubber frame 501 and configured to ensure that a magnetic device is mounted to the dust box filter to be installed in a predetermined position. The magnetic device may be a magnet or other electromagnetic element, and an inductive magnetic device is mounted in the magnetic device mounting hole 504. The magnetic device mounting hole 504 has sufficient depth to mount the magnetic device to a fixed position inside the filter, and the entire filter can be detected by a Hall sensor when it is mounted to the fixed position, ensuring that the filter is installed in a predetermined position.

[0082] In some embodiments, as shown in Figure 11, the soft rubber frame further includes a second rib position 5041, which is located around the magnetic device mounting hole and configured to prevent liquid from entering the magnetic device mounting hole. The second rib position 5041 tightly encloses the outer end of the magnetic device outside the magnetic device mounting hole 504, thereby preventing the magnetic device from rusting and failing. The second rib position 5041 may be made of a soft rubber material and further encloses the magnetic device when pressed.

[0083] In some embodiments, as shown in Figure 11, the soft rubber frame further includes a grommet 505, which is positioned to extend outward from the stepped surface 503 and is configured to facilitate the removal of the dust box filter. The shape and structure of the grommet 505 are not limited and may be semicircular, square, rectangular, or the like.

[0084] In some embodiments, as shown in Figure 12, the soft rubber frame further includes a hollow structure 508, which is provided on the first and / or second side walls of the frame and configured to reduce the overall weight of the frame, and the hollow structure 508 may be a plurality of inwardly recessed fastening holes, the structure of which is not limited and may be circular, square, rectangular, irregular, etc.

[0085] In the automatic cleaning device described above, the dust box filter adopts a soft rubber frame design. During the assembly process, the soft rubber frame is directly pressed and assembled into the dust box opening. Simultaneously, by cooperating with structures such as the first projection, the inner sealing lip, and the outer sealing lip, the filter and assembly surface are tightly sealed during assembly. This avoids the conventional process of manually bonding the assembly parts with dot adhesive after installation on the filter, simplifying the process, reducing the number of assembly parts, lowering costs, eliminating the need for adhesive bonding, resulting in no odor and a more environmentally friendly design.

[0086] Finally, note that each example in this specification is described incrementally, each example focuses on its differences from the others, and identical or similar parts between examples may be referenced to one another.
