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.
[0027] Hereinafter, optional embodiments of the present application will be described in detail with reference to the accompanying drawings.
[0028] 1 and 2 are schematic structural diagrams of an automatic cleaning device according to some embodiments. 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.
[0029] The mobile platform 100 is configured to automatically move across an operating surface in a target direction. 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 works on a floor surface, and the floor surface is the operating surface; the automatic cleaning device may be a window cleaning robot, where the automatic cleaning device works on a glass exterior surface of a building, and the glass exterior surface is the operating surface; or the automatic cleaning device may be a pipe cleaning robot, where the automatic cleaning device works on an inner surface of a pipe, and the inner surface of the pipe is the operating surface. Purely for purposes of illustration, the automatic cleaning device will be described in the present application as a mopping robot.
[0030] In some embodiments, mobile platform 100 may be an autonomous mobile platform or a non-autonomous mobile platform. An autonomous mobile platform means that mobile platform 100 itself can automatically and adaptively make operational decisions in response to unexpected environmental inputs. A non-autonomous mobile platform cannot adaptively make operational decisions in response to unexpected environmental inputs, but can operate according to a predetermined procedure or logic. Correspondingly, if mobile platform 100 is an autonomous mobile platform, the target direction may be determined autonomously by an automatic cleaning device. If mobile platform 100 is a non-autonomous mobile platform, the target direction may be set by a system or manually. If mobile platform 100 is an autonomous mobile platform, mobile platform 100 is composed of a forward-facing portion 111 and a backward-facing portion 110.
[0031] The sensing system 120 includes a positioning device 121 located above the mobile platform 100, a buffer 122 located on the forward portion 111 of the mobile platform 100, a cliff sensor 123 located on the bottom of the mobile platform, and other 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.
[0032] 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 about 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 is substantially defined by the center point of the drive wheel assembly 141, and its axis center extends between the right and left wheels of the automatic cleaning device. Here, the automatic cleaning device can rotate about the Y axis. When the forward-facing portion of the automatic cleaning device tilts upward and the rear-facing portion tilts downward, this is referred to as "pitch up." When the forward-facing portion of the automatic cleaning device tilts downward and the rear-facing portion tilts upward, this is referred to as "pitch down." Furthermore, the automatic cleaning device can rotate about the Z axis. When the automatic cleaning device tilts to the right of the X axis at the front of the automatic cleaning device, this is referred to as "turn right," and when the automatic cleaning device tilts to the left of the X axis, this is referred to as "turn left."
[0033] 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 traveling direction, and the "rear" refers to the side opposite to the automatic cleaning device's traveling direction.
[0034] Specific types of position determining device 121 include, but are not limited to, a camera, a laser ranging device (LDS), and the like.
[0035] Each assembly in the sensing system 120 may operate independently or may work in concert to more accurately achieve its purpose and function. The cliff sensor 123 and ultrasonic sensor identify the surface to be cleaned and determine the physical characteristics of the surface to be cleaned, including the surface material, cleanliness, etc., which can be combined with cameras, laser ranging devices, etc. for more accurate determination.
[0036] For example, an ultrasonic sensor may be used to determine whether the surface to be cleaned is carpeted, and if the ultrasonic sensor determines that the surface to be cleaned is carpeted, the control system 130 may control the automatic cleaning device to perform a carpet mode cleaning.
[0037] A buffer 122 is provided on the forward-facing portion 111 of the mobile platform 100, and when the drive wheel assembly 141 propels the automatic cleaning device to travel on the floor surface during the cleaning process, the buffer 122 detects one or more events (or objects) in the travel path of the automatic cleaning device via a sensor system, for example, an infrared sensor, and the automatic cleaning device may detect the event (or object), for example, an obstacle, a wall, through the buffer 122 and control the drive wheel assembly 141 so that the automatic cleaning device responds to the event (or object), for example, moves away from the obstacle.
[0038] 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, that communicates with a non-transitory memory, such as a hard disk, flash memory, or random access memory. The application processor receives environmental information sensed by the multiple sensors from the sensing system 120 and obstacle information fed back from the laser ranging 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 turning of the drive system 140 according to the autonomously determined travel path. Furthermore, the control system 130 can determine whether to activate the cleaning module 150 to perform a cleaning operation based on the environmental information and the environmental map.
[0039] In some embodiments, 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 crossing a threshold, riding on a carpet, being positioned on a cliff, being caught above or below, the dustbin being full, or being lifted, and provides specific next operating strategies according to different situations, allowing the operation of the automatic cleaning device to better meet the owner's requirements and provide a better user experience. Furthermore, the control system can plan the most efficient and rational cleaning path and cleaning method according to the instant map information drawn by SLAM, thereby significantly improving the cleaning efficiency of the automatic cleaning device.
[0040] Based on specific distance and angle information, such as x, y, and θ components, the drive system 140 can execute drive commands to steer the automatic cleaning device to travel 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.
[0041] 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 direction-changing assemblies 142, and the direction-changing assemblies 142 may be driven wheels or driving wheels, and their structural form may be universal wheels, and the direction-changing assemblies 142 may be located in front of the driving wheel assemblies 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 low battery voltage monitoring circuit, which are in turn connected to a microcomputer control circuit. The host computer is connected to the charging pile via charging electrodes located on the side or bottom of the main body. If dust adheres to the exposed charging electrodes, the accumulated charge during charging can cause the plastic body around the electrodes to melt and deform, eventually deforming the electrodes themselves and preventing normal charging.
[0043] The man-machine interactive system 170 includes buttons on a host panel that can be used by a user to select functions, and may further include a display screen and / or indicator lights and / or a speaker, which can display the current status or function options of the device to the user, and may further include a mobile phone client program. In the case of a route navigation type automatic cleaning device, the mobile phone client can display to the user a map of the environment in which the device is installed and the location of the device, providing the user with a richer and more user-friendly range of functions.
[0044] As shown in FIG. 2, cleaning module 150 may include a dry cleaning module 151 .
[0045] The dry cleaning module 151 includes a roller brush, dust box, fan, and air outlet. The roller brush, which is in contact with the floor, sweeps dust from the floor toward the dust inlet between the roller brush and the dust box. The fan generates suction gas, which passes through the dust box and sucks the dust into the dust box. The dust removal capacity of a vacuum cleaner is measured by its dust pickup efficiency (DPU). DPU is affected by the structure and material of the roller brush, the wind power utilization rate of the duct consisting of the dust inlet, 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 conventional plug-in dust vacuum cleaners, improved dust removal capacity is crucial 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 now 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 capability provides the most obvious and significant user experience, allowing users to directly conclude whether the machine cleans or wipes clean. The dry cleaning module may further include 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.
[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] 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 requires designing decorative top casing parts on the top flap, which increases costs. While the decorative top casing parts and top flap can conceal and protect internal components, they also complicate the overall machine structure, increase costs, and impact design space for the dust box under the top flap.
[0048] In this regard, embodiments of the present application 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 the same structure achieves the same technical effects, so some technical effects will not be repeated herein. Specifically, the present application provides an automatic cleaning device, which, as shown in Figures 3 to 5, includes a moving platform 100 configured to automatically move an operation surface, and the moving platform 100 includes a storage cavity 200. In some embodiments, the storage cavity 200 is located rearward in the forward direction of the automatic cleaning device, and 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, which is detachably assembled to the receiving cavity 200, wherein the first cavity 201 and the second cavity 202 are arranged adjacent to each other in the front-to-back direction in the forward movement 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 front-to-back direction in the forward movement of the automatic cleaning device, and a larger portion of the dust box in volume and weight is located closer to the center of the automatic cleaning device, which allows the dust box to be more stably positioned in the receiving cavity 200 and stabilizes the center of gravity of the entire cleaning device, making it more stable during processes such as moving forward, turning, and crossing obstacles, and less likely to tip over. At the same time, the dust box storage section and the dust box top cover are made into an integrated 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, eliminating the flip cover structure of conventional cleaning devices. At the same time, the dust suction port, located approximately in the center of the bottom of the cleaning device, can be easily aligned directly with the dust box, allowing dust to enter the dust box directly from the dust suction port, reducing the process of dust entering the interior of the device and avoiding 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 accommodated with different 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, and an air outlet 208 is provided on the rear wall of the connection between the first cavity 201 and the second cavity 202. The air outlet 208 has a grill structure, and a fan is accommodated in the space below the second cavity 202 and is supported by a fan bracket. In some embodiments, the air outlet 208 forms part of the fan bracket, and an air outlet 204 is provided on the rear wall of the moving platform 100. Under the suction force of the fan, dust enters the dust box 300 through the dust suction port 203, and the airflow is filtered by the dust box filter before being discharged through the air outlet 204.
[0049] In some embodiments, the dust box 300 includes a receiving portion 301 and a top cover 302 disposed above the receiving portion 301, and the top cover 302 is fixedly connected to the receiving portion 301. The fixed connection method may include, but is not limited to, adhesive bonding, welding, integral molding, bolting, fastening, etc. The receiving portion 301 is used to receive dust sucked through the dust suction port 203, and the appearance of the receiving portion 301 substantially matches the first cavity 201.
[0050] The roller brush, which is in contact with the floor surface to a certain extent, sweeps up the dust on the floor surface, and under the action of the negative pressure airflow generated by the fan, the dust is wound in front of the dust suction port 203 between the roller brush and the dust box 300, and then sucked into the dust box 300 by the suction airflow generated by the fan that passes through the dust box 300, and the dust is isolated inside the dust box 300 by the filter 500, and the filtered air flows into the fan.
[0051] In some embodiments, the receiving portion 301 of the dust box 300 has a first opening 3011 at the front side of the dust box 300, which is aligned with the dust suction port 203, and the receiving portion 301 has a second opening 3012 at the rear side of the dust box, and the filter 500 is disposed 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 to facilitate removal and cleaning of 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.
[0052] In some embodiments, the top cover 302 includes a first portion 3021 that covers the accommodating portion 301 and a second portion 3022 that protrudes from the accommodating portion 301 and extends outward. When the dust box 300 is assembled to the accommodating cavity 200, the accommodating 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 substantially matches the top portion of the first cavity 201 and the structure of the second cavity 202, thereby ensuring that the dust box 300 is stably installed in the receiving 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 precisely covers the receiving section and the fan, and the upper surface of the dust box top cover is approximately level with the upper surface of the moving platform, ensuring the flatness of the outer surface of the automatic cleaning device and improving the overall coordination of the appearance. It provides more spatial options for the design of each component, including the receiving section, on the underside of the top cover, making it easier to position different components, improving the volume options of the dust box, allowing specific sizes to be set as needed, without affecting the overall opening size of the receiving cavity and reducing molding costs.
[0053] In some embodiments, the first portion 3021 of the top cover 302 includes a peripheral edge 30211 that protrudes outward from the edge contour of the storage compartment. The storage cavity 200 includes a step 205 that extends around the edge of the top end of the storage cavity, and the step 205 is configured to receive at least a portion of the peripheral edge 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 flush with the top surface of the moving platform. The storage cavity 200 includes a step 205 that extends around the edge of the top end of the storage cavity, and can entirely receive the edge of the top cover 302. The top cover 302 is received in the storage cavity 200 in a substantially tight manner, which can prevent foreign objects from directly falling into gaps at the edge of the dust box and becoming caught in the dust box, while at the same time maintaining the appearance of the top cover as the top surface of an automatic cleaning device.
[0054] In some embodiments, a support structure 3023 configured to support the second portion 3022 of the top cover 302 is provided below the second portion 3022 of the top cover 302. In some embodiments, the support structure 3023 is integrally molded with at least a portion of the receiving portion 301, which increases the support force of the support structure 3023 on the second portion 3022 of the top cover 302 and effectively prevents damage to the second portion 3022. The support structure 3023 may include, but is not limited to, an arc-shaped structure or a linear structure. For example, the support structure 3023 may be two arc-shaped structures symmetrically arranged so as to substantially match the outer edge contour of the second portion 3022 of the top cover 302.
[0055] In some embodiments, a groove 2021 is provided on the lower surface of the second cavity 202, and the groove 2021 substantially matches the contour of the support structure 3023, so that when the second part 3022 of the top cover is received in the second cavity 202, the support structure 3023 is received in the groove 2021 and the upper surface of the top cover 302 is substantially horizontal.
[0056] In some embodiments, the top cover 302 is symmetrically arranged along the central axis of the forward movement of the automatic cleaning device. In some embodiments, as shown in Figures 6A to 6H, the top cover has at least one shape selected from the group consisting of a D-shape, a rectangle, a square, a circle, an oval, a triangle, a square, a pentagon, a hexagon, a heptagon, and an octagon, or a combination thereof. The symmetrical arrangement allows the device to maintain its appearance without being covered by an outer cover, and also facilitates the installation and removal of the dust box.
[0057] In some embodiments, as shown in FIG. 8, the first cavity 201 includes a first locking member 701, and as shown in FIG. 10, the second cavity 202 includes a second locking member 72, as shown in FIGS. 5 and 7, the first portion 3021 of the top cover includes a first locking member 601, and as shown in FIG. 9A, the second portion 3022 of the top cover includes a second locking member 602, and the first locking member 601 cooperates with the first locking member 701 to lock, and the second locking member 602 cooperates with the second locking member 72 to lock.
[0058] The above embodiment relates to a dust box for an automatic cleaning device and its mounting structure, in which a receiving cavity is provided on the rear side of the automatic cleaning device in the forward direction, the receiving cavity including a first cavity and a second cavity, and the depth of the first cavity is greater than the depth of the second cavity. After the dust box is installed in the receiving cavity, the top surface of the dust box top cover is substantially flush with the top surface of the moving platform, thereby simplifying the top structure of the automatic cleaning device, reducing production costs, and simultaneously increasing the design space of the receiving cavity.
[0059] Existing automatic cleaning devices are equipped with pop-up dustbins and non-pop-up dustbins, and the pop-up dustbin top flap and flip mechanism. 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 many other components may prevent the dustbin from popping up normally, negatively impacting use. Non-pop-up dustbins often use complex locking mechanisms, the spring assemblies of which are prone to breakage due to aging, and the pressing member does not fit well with the fingers when operating, resulting in a poor overall user experience.
[0060] In this regard, an embodiment of the present application 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. This embodiment will briefly describe some structural features compared to the above embodiment, but the same structure has similar technical effects, and some technical effects will not be repeated herein. Specifically, as shown in Figures 1 to 5 and 7, the automatic cleaning device is configured to automatically move on an operation 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 substantially on the central axis of the top cover, the first locking mechanism 610 including at least a first grommet recess 603 and a first locking member 601, the first locking member 601 located within the first grommet recess 603, and the first locking member 601 being able to resiliently move relative to the first grommet recess 603 under the action of an external force. The first grommet recess 603 is a recess formed downward along the edge of the first portion of the top cover, the first grommet recess 603 having a sufficient depth in the Z direction, such that the height of the first locking member 601 is lower than the surface of the top cover, and the first grommet recess 603 having a sufficient resilient space in the X direction, such that the first locking member 601 is able to move resiliently inward.
[0061] In some embodiments, the first locking member 601 includes a first resilient arm 6011, a first grommet portion 6012, and a first buckle portion 6013, wherein the first resilient arm 6011 extends upward from the bottom of the first grommet recess portion 603, the first grommet portion 6012 is provided at the upwardly extending end of the first resilient arm 6011, and the first buckle 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, although this shape is not limited. The first grommet portion 6012 is provided above the first resilient arm 6011 in the lateral direction, and has a bottom surface that protrudes substantially outward and a grommet surface that extends upward along the bottom surface, with the grommet surface extending to a position that is substantially flush with the top cover. The grommet surface may be an arc-shaped structure, i.e., its projection onto a horizontal plane is arc-shaped, and the grommet surface facilitates manual operation and is ergonomically more suitable for receiving force by conforming to the shape of the fingers. In some embodiments, the first buckle portion 6013 is a pair of sheet structures symmetrically arranged along both sides of the first elastic arm 6011. To facilitate insertion of the first locking member 701, the sheet structures have a width from the root portion to the free end that narrows from large to small. The first elastic arm 6011 as a whole may be formed from a common elastic material, such as plastic or an organic elastic material.
[0062] In some embodiments, as shown in Figure 8, which is an enlarged schematic view of the first locking member 701 in A of Figure 3A, the first locking member 701 is provided at a location on the inner wall of the receiving cavity 200 that roughly 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.
[0063] In some embodiments, a first recess 206 is provided at a location on the inner wall of the receiving cavity that roughly corresponds 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 the access operation by the finger easier and more convenient.
[0064] 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 has a notch, such as an arc-shaped or rectangular notch, formed on the inside along approximately the midline of the second portion 3022 of the top cover, for easy finger reach for snapping. The second locking member 602 is located below the second grommet recess 605, which provides sufficient space for finger control of the second locking member 602, allowing the second locking member 602 to resiliently move inward under the action of an external force. Specifically, the second locking member 602 includes a second elastic arm 6021, a second grommet portion 6022, and a second buckle portion 6023, where the second elastic arm 6021 is located below the second grommet recess 605 and 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 direction of the top cover, and then extends along the edge direction of the second grommet recess 605. Here, the opening direction of the second grommet recess portion 605 is in direction A, which is from the center of the top cover outward, as shown in Figure 9A, and in this embodiment it is also toward the rear of the dust box top cover. The two parts of the second elastic arms 6021 are arranged symmetrically connected in approximately two ``box'' shaped structures, and the second grommet portion 6022 is connected to the two parts of the second elastic arms 6021 arranged symmetrically, and the second grommet portion 6022 is arranged above the two second elastic arms. 9C is an enlarged view of the second grommet portion at C in FIG. 9B. As shown in FIGS. 9B and 9C, the bottom of the second grommet portion 6022 is provided with a bottom surface 60221 that protrudes substantially outward and a grommet surface 60222 that extends upward along the bottom surface, and the grommet surface extends to a position where it is substantially flush with the top cover. The grommet surface may have an arc-shaped structure, and the grommet surface facilitates manual operation and allows fingers to easily apply force.In some embodiments, the second grommet portion 6022 is integrally molded with the symmetrically arranged second elastic arms 6021, and the second buckle portion 6023 is provided on a horizontally extending portion of the second elastic arms. The second buckle portions 6023 are symmetrically arranged along both sides of the pair of second elastic arms 6021, and have, for example, a protrusion or sheet structure extending along the A direction. In some embodiments, each second buckle portion 6023 has a groove extending inward from an end of the second buckle portion 6023. The groove prevents the entire second buckle portion from being excessively deformed after molding and cooling, making snapping difficult. In some embodiments, the second locking member 602 further includes symmetrically arranged connecting members 6024. The connecting members 6024 are substantially planar. One end of the second elastic arms 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 to an end surface of a support structure. The second grommet portion 6022 is exposed from the second grommet recess 605 in the X direction, and when unlocking, a finger reaches the second grommet recess 605 and presses the second grommet portion 6022, applying force to the inside of the dust box along the X axis and elastically contracting the second buckle portion 6023 inward, causing the second buckle portion 6023 to pop up from the bottom of the second locking member 702, thereby achieving unlocking. The second elastic arm 6021 as a whole is generally formed from an elastic material such as plastic or an organic elastic material.
[0065] In some embodiments, as shown in FIG. 10, which is an enlarged view of the second locking member 702 at point B in FIG. 3B, the second locking member 702 is provided at a location on the inner wall of the receiving cavity 200 that roughly corresponds to the second locking member 602, and the second locking member 602 cooperates with the second locking member 702 to lock. The second locking member 702 is a pair of protrusions, and the second buckle portion 602 extends from the bottom of the second locking member 702 to achieve locking. The protrusions may be flat, cylindrical, rectangular, or the like, and are not limited thereto, as long as they can be engaged with the second buckle portion.
[0066] In some embodiments, a second recess 207 is provided on the underside of the second cavity 202 at a location roughly 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 second locking member 602 when the dust box 300 is placed in the storage cavity 200, allowing the entire dust box to be placed in a predetermined position in the storage cavity 200.
[0067] In some embodiments, the top cover includes a first portion covering the receiving portion and a second portion 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.
[0068] In the dustbin locking structure described in the above embodiment, the locking structures are symmetrically arranged in the front and rear directions of the dustbin top cover, and unlocking can be achieved by applying force to the two elastic structures on the front and rear of the dustbin with one hand. This prevents one side from being unlocked and popping up, which could cause the dustbin to tilt. At the same time, the elastic structure is simple, and elastic unlocking can be achieved by forming the elastic arms out of elastic material, eliminating the risk of complex unlocking devices such as springs being easily damaged.
[0069] In some embodiments, as shown in FIG. 4 , the second locking mechanism 620 includes at least one first magnetic attraction module 604, which is disposed between the second portion of the top cover and the support structure. As shown in FIG. 3A , the receiving cavity includes at least one second magnetic attraction module 606 configured to cooperate with the first magnetic attraction module 604 to be attracted and locked. During use, the first locking member 601 corresponding to the dustbin can be retracted by manually pressing the first locking member 601 and the second grommet recess 605. After the dustbin is placed in the receiving cavity and released, the first buckle 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.
[0070] In some embodiments, the second locking mechanism 620 as described above may be an embodiment including a second grommet recess 605 and a second locking member 602, an embodiment including a first magnetic attraction module 604, or an embodiment including both, but is not limited thereto.
[0071] The dust box of an existing automatic cleaning device must be equipped with a replaceable dust box filter. Conventional filters generally have a rigid frame made of plastic or metal, a cascading filter medium inserted into the frame, and a 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 of the conventional dust box is complicated, the filter installation process is cumbersome, labor and cost are wasted, and the sealing adhesive is uneconomical and environmentally unfriendly.
[0072] In this regard, an embodiment of the present application provides an automatic cleaning device, which is configured to automatically move on an operating surface and includes 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, and the dust box including a dust box filter. The dust box filter is applied to the dust box of the automatic cleaning device, and the assembly process of the dust box filter is simplified. This embodiment has some simplified structural features compared to the above embodiment, but the same structure has similar technical effects, and some technical effects will be omitted here. As shown in Figures 11 and 12, the dust box filter 500 includes a soft rubber frame 501, which includes at least one soft rubber protrusion for sealing the assembly gap with the dust box during assembly, and a filter medium 502 sleeved within the soft rubber frame 501, where the soft rubber frame 501 is non-detachably connected to the filter medium 502. In some embodiments, the process of non-detachably connecting the soft rubber frame 501 and the filter media 502 includes an overmolding injection process, where the filter media is pre-sleeved in the frame and then a rubber sleeve is added to the sleeved frame combination to integrally form the desired sealing protrusions. Alternatively, a two-shot injection molding process may be used to first inject the hard rubber frame body, then sleeve the filter media onto the frame body, and then inject the soft rubber to form the inner and outer sealing protrusions.
[0073] The soft rubber frame 501 may have a rectangular, square, oval, circular, polygonal, or other shape, and is not limited to these shapes. In some embodiments, as shown in Figures 11 and 12, the soft rubber frame 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. The pair of first side walls 50111 and the pair of second side walls 50113 form a rectangular structural frame, and a filter medium is sleeved within the rectangular structural frame.
[0074] In some embodiments, the first protrusions 5011 and the second protrusions 5015 have a continuous protrusion structure, for example, the first protrusions 5011 and the second protrusions 5015 extend continuously from one end to the other end of the outer circumferential surface of the first side wall 50111. Because the first protrusions 5011 and the second protrusions 5015 are made of soft rubber, when the dust box filter is assembled into the dust box, the first protrusions 5011 and the second protrusions 5015 are pressed to directly seal between the dust box filter 500 and the second opening 3012 of the dust box, and the second opening 3012 of the dust box is in sufficient contact with the inner wall extending substantially along the horizontal direction to be sealed. This replaces the prior art technique of sealing via a sealing strip after the dust box filter is assembled into the dust box.
[0075] In some embodiments, as shown in Fig. 14, at least one of the first protrusion and the second protrusion has an undercut 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. For example, the undercut structure is an arc-shaped structure that is inclined toward the side opposite to the assembly direction of the dust box filter. The undercut structure makes it convenient for the dust box filter to extend into the dust box assembly opening with friction, 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.
[0076] In some embodiments, the second side wall of the soft rubber structure further includes at least one third protrusion 5012, which is distributed on the outer circumferential surface of at least one second side wall 50113 of the frame structure. The third protrusions 5012 may be a dispersed multi-protrusion structure, and in one embodiment, the third protrusions 5012 are distributed on the outer circumferential surfaces of the two second side walls 50113 of the frame structure. When the dust box filter is assembled to the dust box, the third protrusion 5012 on the outer circumferential surface of one second side wall 50113 of the frame structure has a slightly elongated 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 elongated third protrusion 5012 is first inserted into the recess in the dust box side wall and rotated around the third protrusion 5012, and then the other side of the dust box filter is attached to the dust box. The third protrusions 5012 distributed on the outer peripheral surface of another second side wall 50113 of the frame structure have a smoother structure, and when the dust box filter is assembled to the dust box, the third protrusions 5012 on this side are tightly fitted and 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 essentially an S-structure, and includes an inner recess for accommodating the third protrusions 5012 and an outer protrusion locked with the third protrusions 5012, and the outer protrusion can elastically move under the action of an external force to be locked with the third protrusions 5012, as shown in Figure 15, which is a view of the installation structure when the dust box filter is viewed from the bottom end of the dust box. 13A and 13B, the soft rubber frame has a first rib position 510, which is provided on the outer circumferential surface of the second side wall and is configured to prevent the dust box filter from being installed too deeply or too shallowly in the dust box, resulting in an assembly error. During the installation process of the dust box filter in the dust box, after the dust box filter is assembled in place, the first rib position 510 abuts against a pillow position 5014 provided at a corresponding position on the dust box side frame, preventing the filter from further stretching inward and preventing the dust box filter from being installed too deeply in the dust box.At the same time, during the assembly process, if the first rib position 510 is not abutted against the pillow position 5014 of the dust box side frame, as shown in Figure 15, it is considered not to be assembled in the specified position, so that the dust box filter can be prevented from being installed too shallowly in the dust box.
[0077] 13A and 13B, the soft rubber frame further includes an anti-misinstallation protrusion 509, which is provided on the outer circumferential surface of the second side wall and configured to prevent the dust box filter from being installed in the wrong direction. The dust box has a recess corresponding to the anti-misinstallation protrusion 509, and when the dust box filter is installed correctly, the anti-misinstallation protrusion 509 enters the recess to properly assemble the dust box filter. If the dust box filter is installed in the wrong direction, there is no recess on the other side of the dust box, and the anti-misinstallation protrusion 509 prevents the dust box filter from being assembled, instead serving to warn that the dust box filter is installed in the wrong direction and prevent incorrect installation.
[0078] 3A and 3B , in some embodiments, the receiving cavity 200 includes a first cavity 201 and a second cavity 202, which are adjacently arranged in a front-to-back direction 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.
[0079] 11 and 12, the soft rubber frame further includes a sealing inner lip 507, which is provided on a first end surface 50116 of the soft rubber frame 501 around the filter medium 502 and configured to achieve a sealing fit between the dust box filter and an assembly surface 30121 of the second opening 3012 of the dust box. As shown in Fig. 14, the assembly surface 30121 of the second opening 3012 of the dust box is provided on a side of the second opening closer to the inner wall of the dust box, has a substantially planar structure, and is abutted against the first end surface 50116 of the soft rubber frame 501 to assemble it to the soft rubber frame. A sealing outer lip 506 is provided on a second end surface 50115 of the soft rubber frame 501 around the filter medium 502 and 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 assembly surface of the dust box filter and the dust box. Because the sealing inner lip 507 is made of a flexible material, it seals the assembly surface of the dust box filter and the dust box under the action of pressing force, and when the dust box is assembled into the automatic cleaning device, the sealing outer lip 506 of the dust box filter is pressed between the dust box filter and the outside of the grill of the air outlet 208 of the receiving cavity 200, and seals the assembly surface of the dust box filter and the fan bracket. 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 provided below the second cavity 202, and the grill-type air outlet 208 is provided on the side wall connecting the first cavity 201 and the second cavity 202. An inner sealing lip 507 and an outer sealing lip 506 provided on the soft rubber frame 501 realize a sealing fit between the inner end surface of the dust box filter 500 and the assembly surface of the dust box air outlet, and a sealing fit between the outer end surface of the dust box filter 500 and the outer surface of the grill of the air outlet of the receiving cavity 200.The conventional complicated process of adding sealing strips on the inside and outside of the dust box filter to meet the air flow path sealing requirements has been omitted. Instead, the soft rubber frame 501 as a carrier includes a sealing structure including an inner sealing lip 507 and an outer sealing lip 506, which also have a certain degree of flexibility, resulting in a tighter contact, sealing and fitting, a more satisfactory fit, a stronger sealing effect, and the airtight performance of the entire air flow path can be ensured, which plays a role in better protecting the functions of the cleaning device such as dust collection and dust discharge through negative pressure.
[0080] 11 and 12, the soft rubber frame further includes a stepped surface 503, which extends outward along the second end surface 50115 of the soft rubber frame 501, and the stepped surface 503 and the side wall of the soft rubber frame 501 form a stepped structure to prevent the dust box filter from being installed too deeply in the dust box. During the assembly process, as shown in FIG. 14, when the dust box filter enters the dust box assembly opening, the stepped surface 503 abuts against the assembly outer edge of the dust box and is locked on the outer edge of the dust box, thereby preventing the dust box filter from being installed too deeply in the dust box.
[0081] In some embodiments, as shown in FIG. 11 , the soft rubber frame further includes a magnetic device mounting hole 504, which is provided on the second end surface 50115 of the soft rubber frame 501 and is configured to be attached to a magnetic device to ensure that the dust box filter is 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 to allow the magnetic device to 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.
[0082] 11, the soft rubber frame further includes a second rib position 5041, which is disposed around the magnetic device mounting hole and configured to prevent liquid from entering the magnetic device mounting hole. The second rib position 5041 tightly encloses the outer end of the magnetic device outside the magnetic device mounting hole 504, thereby preventing the magnetic device from rusting and breaking down. The second rib position 5041 may be a soft rubber material and further encloses the magnetic device when pressed.
[0083] 11, the soft rubber frame further includes a grommet 505, which is provided at a position extending outward from the stepped surface 503 and configured to facilitate removal of the dust box filter. The shape of the grommet 505 is not limited and may be semicircular, square, rectangular, etc.
[0084] In some embodiments, as shown in FIG. 12 , the soft rubber frame further includes a hollow structure 508, which is provided on the first side wall and / or the second 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 holes, and the shape of the holes is not limited and may be circular, square, rectangular, irregular, etc.
[0085] In the automatic cleaning device described in the above embodiments, the dust box filter adopts a soft rubber frame design. During the assembly process, the soft rubber frame 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 to achieve the effect of tightly sealing the filter and the assembly surface during assembly. This avoids the traditional process of manually gluing the assembly parts with dotted adhesive after the filter is attached, simplifies the process, reduces the number of assembly parts, and at the same time reduces costs. There is no adhesive bonding, no odor, and it is more environmentally friendly.
[0086] Finally, please note that each embodiment in this specification will be described progressively, with each embodiment focusing on differences from other embodiments, and that identical or similar parts between each embodiment may be referenced to each other.
