Unless further limited, an element defined with the term "comprises" does not exclude the presence of other identical elements in a product or device that includes said element.
[0030] Hereinafter, optional embodiments of the present application will be described in detail with reference to the accompanying drawings.
[0031] 1 and 2 are schematic structural diagrams of an automatic cleaning device according to some embodiments. As shown in FIG. 1 and FIG. 2, the automatic cleaning device may be a vacuum cleaning robot, a mopping / brushing robot, a window climbing robot, etc., and the automatic cleaning device is composed of a moving platform 100, a sensing system 120, a control system 130, a driving system 140, a cleaning module 150, an energy system 160, and a human-machine interactive system 170.
[0032] 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. 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 pipe interior surface is the operating surface. Purely for purposes of illustration, the automatic cleaning device is described in the present application as a mopping robot.
[0033] In some embodiments, the mobile platform 100 may be an autonomous mobile platform or a non-autonomous mobile platform. The autonomous mobile platform means that the mobile platform 100 itself can automatically and adaptively make operational decisions in response to unexpected environmental inputs, while the non-autonomous mobile platform itself cannot adaptively make operational decisions in response to unexpected environmental inputs, but can operate according to a predetermined procedure or a certain logic. Correspondingly, when the mobile platform 100 is an autonomous mobile platform, the target direction may be determined autonomously by an automatic cleaning device, and when the mobile platform 100 is a non-autonomous mobile platform, the target direction may be set by a system or manually. When the mobile platform 100 is an autonomous mobile platform, the mobile platform 100 is composed of a forward-facing part 111 and a backward-facing part 110.
[0034] The sensing system 120 includes a positioning device 121 located above the mobile platform 100, a buffer 122 located on the forward portion 111 of the mobile platform 100, a cliff sensor 123 located at the bottom of the mobile platform, and other sensing devices such as ultrasonic sensors (not shown), infrared sensors (not shown), magnetometers (not shown), accelerometers (not shown), gyroscopes (not shown), and odometers (not shown), and provides various position information and moving status information of the equipment to the control system 130.
[0035] In order to more clearly describe the behavior of the automatic cleaning device, the following directions are defined. The automatic cleaning device can move on the floor surface by various combinations of movement about three mutually perpendicular axes defined by the mobile platform 100: the lateral axis Y, the front-rear axis X, and the central vertical axis Z. The forward drive direction along the front-rear axis X is designated as "forward", and the rear drive direction along the front-rear axis X is designated as "rear". The lateral axis Y extends between the right and left wheels of the automatic cleaning device along an axis center substantially defined by the center point of the drive wheel assembly 141. Here, the automatic cleaning device can rotate about the Y axis. If the forward facing part of the automatic cleaning device is tilted upward and the rear facing part is tilted downward, it is called "pitch up", and if the forward facing part of the automatic cleaning device is tilted downward and the rear facing part is tilted upward, it is called "pitch down". In addition, the automatic cleaning device can rotate about the Z axis. If the automatic cleaning device is tilted to the right of the X axis at the front of the automatic cleaning device, it is called "turn right", and if the automatic cleaning device is tilted to the left of the X axis, it is called "turn left".
[0036] 2, cliff sensors 123 are provided at the bottom of the moving platform 100, in front of and behind the drive wheel assembly 141. The cliff sensors 123 can prevent the automatic cleaning device from falling when retreating, and prevent damage to the automatic cleaning device. The "front" refers to the same side as the traveling direction of the automatic cleaning device, and the "rear" refers to the opposite side to the traveling direction of the automatic cleaning device.
[0037] Specific types of position determining device 121 include, but are not limited to, a camera, a laser distance measuring device (LDS), and the like.
[0038] Each assembly in the sensing system 120 may operate independently or in concert to achieve more precise purpose and function. The cliff sensor 123 and ultrasonic sensor identify the surface to be cleaned and determine the physical characteristics of the surface to be cleaned, including surface material, cleanliness, etc., which can be combined with cameras, laser ranging devices, etc. to make more precise determinations.
[0039] 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.
[0040] A bumper 122 is provided on the forward-facing portion 111 of the moving platform 100, and when the drive wheel assembly 141 propels the automatic cleaning device to travel on the floor surface during the cleaning process, the bumper 122 detects one or more events (or objects) in the travel path of the automatic cleaning device via a sensor system, e.g., an infrared sensor. The automatic cleaning device may control the drive wheel assembly 141 in response to the event (or object), e.g., through an obstacle, wall, detected by the bumper 122, so that the automatic cleaning device moves away from the obstacle, for example.
[0041] The control system 130 is provided on a circuit board in the mobile platform 100 and includes a central processing unit, an application processor, etc., which communicates with a non-transitory memory such as a hard disk, a flash memory, a random access memory, etc., and the application processor receives the environmental information sensed by the multiple sensors from the sensing system 120, the obstacle information fed back from the laser ranging device, etc., and uses a positioning algorithm, such as SLAM, to draw an instant map of the environment in which the automatic cleaning device is installed, and autonomously determines a travel path based on the environmental information and the environmental map, and then controls the operation of the drive system 140, such as forward, backward, and / or steering, according to the autonomously determined travel path. Furthermore, the control system 130 can determine whether to activate the cleaning module 150 to perform a cleaning operation based on the environmental information and the environmental map.
[0042] In some embodiments, the control system 130 combines the distance information and speed information fed back from the buffer 122, the cliff sensor 123, and the sensing devices such as the ultrasonic sensor, the infrared sensor, the magnetometer, the accelerometer, the gyroscope, the odometer, etc. to comprehensively determine the current working state of the vacuum cleaner, such as exceeding the threshold, climbing up the carpet, being located on the cliff, being stuck above or below, the dust box being full, being lifted, etc., and gives specific next operation strategies according to different situations, so that the work of the automatic cleaning device can better meet the owner's requirements and give a better user experience. In addition, the control system can plan the most efficient and reasonable cleaning path and cleaning method according to the instant map information drawn by SLAM, which can greatly improve the cleaning efficiency of the automatic cleaning device.
[0043] Based on the specific distance and angle information, such as x, y and θ components, the drive system 140 can execute the drive command to steer the automatic cleaning device to move across the floor surface. As shown in FIG. 2, the drive system 140 includes a drive wheel assembly 141. The drive system 140 can control the left and right wheels simultaneously, and for more precise control of the device operation, the drive system 140 is preferably composed of a left drive wheel assembly and a right drive wheel assembly, respectively. The left drive wheel assembly and the right drive wheel assembly are symmetrically disposed along the horizontal axis defined by the mobile platform 100.
[0044] In order for the automatic cleaning device to move more stably on the floor surface or have a higher mobility, the automatic cleaning device may include one or more steering assemblies 142. The steering assembly 142 may be a driven wheel or a driving wheel, and its structural form may be a universal wheel. The steering assembly 142 may be located in front of the driving wheel assembly 141.
[0045] The energy system 160 includes a rechargeable battery such as a nickel-metal hydride battery or a lithium battery. The rechargeable battery is connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery voltage drop monitoring circuit, which are connected to a microcomputer control circuit. The host computer is connected to the charging pile for charging via a charging electrode provided on the side or bottom of the main body.
[0046] The human-machine interactive system 170 includes a button on the host panel, which is available for the user to select a function, and may further include a display screen and / or an indicator light and / or a speaker, which can display the current status or function options of the device to the user, and may further include a mobile phone client program. In the case of a route navigation type automatic cleaning device, a map of the environment in which the device is installed and the location of the device can be displayed to the user in the mobile phone client, which can provide the user with richer and more convenient function items.
[0047] As shown in FIG. 2, the cleaning module 150 may include a dry cleaning module 151 .
[0048] The dry cleaning module 151 includes a roller brush, a dust box, a fan, and an air outlet. The roller brush, which has some interference with the floor surface, sweeps up the dust on the floor surface to the front of the dust suction port between the roller brush and the dust box, and sucks it into the dust box through the suction gas generated by the fan that passes through the dust box. The dust removal capacity of the vacuum cleaner is characterized by the dust pickup efficiency (DPU). The cleaning efficiency DPU is affected by the structure and material of the roller brush, by the wind power utilization rate of the duct consisting of the dust suction port, the dust box, the fan, the air outlet, and their connecting members, and by the type and power of the fan, which makes it a complex system design problem. Compared with ordinary plug-in dust suction devices, the improvement of the dust removal capacity is of great significance for automatic cleaning devices with energy limitations. The improvement of the dust removal capacity directly and effectively reduces the required energy, that is, a machine that can clean 80 square meters of floors on one charge can be evolved to clean more than 180 square meters on one charge. In addition, by reducing the number of charging times, the battery life is also greatly extended, and users can replace the batteries less frequently. More intuitively and importantly, the improvement of the dust removal ability is the most obvious and important user experience, and the user can directly conclude whether the machine cleans cleanly or wipes cleanly. The dry cleaning module may further include a side brush 152 having a rotating shaft, which is at an angle to the floor surface and moves the dirt to the roller brush area of the cleaning module 150.
[0049] 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, where the wet cleaning module includes a water tank, a cleaning head, a driving unit, etc., where water in the water tank flows along a water circuit to the cleaning head, and the cleaning head cleans at least a portion of the operating surface under the driving of the driving unit.
[0050] In the existing automatic cleaning device, the casing layout frame structure is complicated, there are many parts, many assembly steps, and the process is complicated. The automatic cleaning device needs to add a top flap and a flip mechanism, and the top casing decorative parts and other parts are designed on the top flap, which increases the cost. Although the top casing decorative parts and the top flap can fulfill the functions of covering up ugly things and protecting internal parts, the structure of the entire machine is complicated, the cost is high, and the design space of the dust box under the top flap is affected.
[0051] In contrast, the embodiments of the present application provide an automatic cleaning device without a flip cover. It is possible to enlarge the design space of the dust box and its storage cavity while simplifying unnecessary components of the automatic cleaning device. The same structure provides the same technical effect, and some technical effects are not described in this specification. Specifically, the present application provides an automatic cleaning device, which includes a moving platform 100 configured to automatically move an operation surface, as shown in Figs. 3 to 5, and the moving platform 100 includes a storage cavity 200. In some embodiments, the storage cavity 200 is provided on a side biased toward the rear in the forward direction of the automatic cleaning device, and the storage 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, and the dust box 300 is detachably assembled to the storage cavity 200. Here, the first cavity 201 and the second cavity 202 are sequentially arranged adjacent to each other in the forward direction of the automatic cleaning device, and the depth of the first cavity 201 is deeper than the depth of the second cavity 202. The first cavity 201 and the second cavity 202 are arranged adjacent to each other in the forward direction of the automatic cleaning device, and a larger part of the volume and weight of the entire dust box is located closer to the center of the automatic cleaning device, so that the dust box is more stably arranged in the accommodating cavity 200, making the center of gravity of the entire cleaning device more stable, and it is stable during the processes of moving forward, turning, crossing obstacles, etc., and is not easily overturned. At the same time, the dust box accommodating part and the dust box top cover are integrated into one structure, and the dust box top cover functions as part of the top surface of the moving platform and is flush with the other parts of the top surface of the moving platform. This omits the flip cover structure of the conventional cleaning device, and allows the dust suction port located approximately in the center of the bottom of the cleaning device to be easily and directly aligned with the dust box, so that dust can directly enter the dust box from the dust suction port, reducing the movement of dust entering the inside of the device, and avoiding dust pollution inside the device.The depth of the first cavity 201 is greater than that of the second cavity 202, so that the dust box and the dust box top cover can be accommodated in a separate structure, and the integrated design of the dust box top cover is facilitated. A dust suction port 203 is provided at the bottom of the front wall of the first cavity 201, and an air outlet 208 is provided at the rear wall of the connection between the first cavity 201 and the second cavity 202. The air outlet 208 has a grill structure. A fan is accommodated in the space below the second cavity 202, and the fan is supported by a fan bracket. In some embodiments, the air outlet 208 forms a part of the fan bracket, and an exhaust port 204 is provided at the rear wall of the moving platform 100. Under the suction force of the fan, dust enters the dust box 300 through the dust suction port 203, and the airflow is filtered by the dust box filter and then exhausted through the exhaust port 204.
[0052] In some embodiments, the dust box 300 includes a receiving portion 301 and a top cover 302 above the receiving portion 301, and the top cover 302 is fixedly connected to the receiving portion 301. The fixed connection method includes, but is not limited to, gluing, 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 is substantially the same as that of the first cavity 201.
[0053] The roller brush, which interferes with the floor surface to a certain extent, sweeps up the dirt on the floor surface, and under the action of the negative pressure airflow generated by the fan, the dirt 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 passing through the dust box 300 generated by the fan, and the dirt is isolated inside the dust box 300 by the filter 500, and the filtered air flows into the fan.
[0054] In some embodiments, the accommodating section 301 of the dust box 300 has a first opening 3011 at the front side of the dust box 300. The first opening 3011 is aligned with the dust suction port 203. The accommodating section 301 has a second opening 3012 at the rear side of the dust box. The filter 500 is provided at 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, which makes it easy to attach, detach, and wash the filter. Here, the front side refers to the side along the forward direction of the automatic cleaning device after the dust box 300 is assembled in the accommodating cavity 200 in the X direction, and the rear side refers to the opposite side to the forward direction of the automatic cleaning device in the X direction.
[0055] In some embodiments, the top cover 302 includes a first portion 3021 covering the receiving portion 301 and a second portion 3022 protruding outward from the receiving portion 301. When the dust box 300 is assembled to the receiving cavity 200, the receiving portion 301 and the first portion 3021 of the top cover 302 are received in the first cavity 201, and the second portion 3022 of the top cover 302 is received in the second cavity 202. The top cover 302 substantially matches the top portion of the first cavity 201 and the structure of the second cavity 202. This allows the dust box 300 to be stably installed in the accommodating cavity 200, and prevents the dust box from shaking due to vibration during the operation of the automatic cleaning device; at the same time, the dust box top cover can exactly cover the position of the accommodating part and the fan, the upper surface of the dust box top cover is approximately level with the upper surface of the moving platform, the flatness of the outer surface of the automatic cleaning device is ensured, the overall appearance is better coordinated, more space options are provided for the design of each component, including the accommodating part, on the underside of the top cover, which is convenient for arranging the positions of different components, the volume options of the dust box are improved, specific sizes can be set as needed, and the molding costs can be reduced without affecting the overall opening size of the accommodating cavity.
[0056] In some embodiments, the first portion 3021 of the top cover 302 includes an edge 30211 that protrudes from the edge contour of the storage portion and extends outward. The storage cavity 200 includes a step 205 that extends around the top edge of the storage cavity. The step 205 is configured to receive at least a portion of the edge 30211 and at least a portion of the outer edge of the second portion 3022. This allows the top surface of the top cover to be substantially flush with the top surface of the moving platform. The storage cavity 200 includes a step 205 that extends around the top edge of the storage cavity, and can fully receive the edge of the top cover 302, and the top cover 302 is received in the storage cavity 200 in a substantially gapless manner, which can prevent foreign objects from directly falling into the gap at the edge of the dust box and getting caught in the dust box, and at the same time ensure the appearance of the top cover as the top surface of an automatic cleaning device.
[0057] In some embodiments, a support structure 3023 configured to support the second part 3022 of the top cover 302 is provided below the second part 3022 of the top cover 302. In some embodiments, the support structure 3023 is integrally molded with at least a part of the receiving part 301, which can increase the support force of the support structure 3023 on the second part 3022 of the top cover 302 and effectively avoid damage thereto. The support structure 3023 includes, but is not limited to, an arc-shaped structure and a linear structure. For example, the support structure 3023 is two symmetrically arranged arc-shaped structures that substantially match the outer edge contour of the second part 3022 of the top cover 302.
[0058] In some embodiments, a groove 2021 is provided on the bottom surface of the second cavity 202. The groove 2021 substantially matches the contour of the support structure 3023, such that when the second portion 3022 of the top cover is received in the second cavity 202, the support structure 3023 is received in the groove 2021 and the top surface of the top cover 302 is substantially horizontal.
[0059] In some embodiments, the top cover 302 is symmetrically arranged along the central axis of the forward direction of the automatic cleaning device. In some embodiments, as shown in Figures 6A to 6H, the top cover shape is at least one of a D-shape, a rectangle, a square, a circle, an ellipse, a triangle, a square, a pentagon, a hexagon, a heptagon, or an octagon, or a combination thereof. By symmetrically arranging the top cover, the appearance of the device can be maintained even if it is not covered with an outer cover, and the dust box can be easily installed and removed.
[0060] In some embodiments, as shown in FIG. 8, the first cavity 201 includes a first locking member 701. As shown in FIG. 10, the second cavity 202 includes a second locking member 72. As shown in FIGS. 5 and 7, the top cover first portion 3021 includes a first locking member 601. As shown in FIG. 9A, the top cover second portion 3022 includes a second locking member 602. The first locking member 601 cooperates with the first locking member 701 to lock, and the second locking member 602 cooperates with the second locking member 72 to lock.
[0061] The above embodiment relates to a dust box of an automatic cleaning device and its mounting structure, in which an accommodating cavity is provided on the rear side of the forward direction of the automatic cleaning device, the accommodating cavity includes a first cavity and a second cavity, the depth of the first cavity is greater than the depth of the second cavity, and after the dust box is assembled into the accommodating cavity, the top surface of the dust box top cover is substantially flush with the top surface of the moving platform, thereby simplifying the top surface structure of the automatic cleaning device, reducing production costs, and at the same time increasing the design space of the accommodating cavity.
[0062] Existing automatic cleaning devices are provided with a pop-up dust box, a non-pop-up dust box, a pop-up dust box top flap and a flip mechanism. When attaching or detaching the dust box, the top flap needs to be opened and the dust box needs to be pressed to pop up. In this embodiment, a complex dust box pop-up mechanism needs to be provided, and the dust box pop-up mechanism includes multiple parts such as a spring, and the elasticity of the spring is reduced by repeated use, so that the dust box cannot be popped up smoothly. In addition, the dust box may not be able to pop up normally due to many other parts, which has a negative impact on use. Non-pop-up dust boxes mostly adopt a locking structure with a complex structure, in which the spring assembly is easily damaged due to aging, and the pressing member does not fit well with the fingers when operating, resulting in a poor overall user experience.
[0063] In this respect, the 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. In this embodiment, some structural features are briefly described compared with the above embodiment, but the same structure has the same technical effect, and some technical effects are omitted in this specification. Specifically, as shown in Figs. 1 to 5 and 7, the automatic cleaning device includes a moving platform 100 configured to automatically move on an operation surface and including a storage cavity 200 at the rear side in the forward direction, and a cleaning module including a dust box 300. The dust box 300 is detachably assembled to the storage cavity 200. The dust box includes a storage portion 301, a top cover 302 above the storage portion, and a locking mechanism. The locking mechanism includes a first locking mechanism 610 located substantially on the central axis of the top cover. Here, the first locking mechanism 610 includes at least a first grommet recess portion 603 and a first locking member 601. The first locking member 601 is located in the first grommet recess 603, and the first locking member 601 can elastically move relative to the first grommet recess 603 under the action of an external force. The first grommet recess 603 is recessed downward along the edge of the first part of the top cover, and the first grommet recess 603 provides a sufficient depth in the Z direction. The height of the first locking member 601 is lower than the surface of the top cover, and the first grommet recess 603 provides a sufficient elastic space in the X direction to provide sufficient movement space for the first locking member 601 to elastically move inward.
[0064] In some embodiments, the first locking member 601 includes a first elastic arm 6011, a first grommet portion 6012, and a first buckle portion 6013. Here, the first elastic arm 6011 extends upward from the bottom of the first grommet recess 603. The first grommet portion 6012 is provided at the end of the first elastic arm 6011 that extends upward. The first buckle portion 6013 extends along the lateral direction of the first elastic arm 6011. For material reduction and increased elasticity, the first elastic arm 6011 is generally in a substantially "U" shape as a whole, but is not limited to this shape structure. The first grommet portion 6012 is provided laterally above the first elastic arm 6011. The first grommet portion 6012 has a bottom surface that substantially protrudes outward and a grommet surface that extends upward along the bottom surface. The grommet surface extends to a position substantially flush with the top cover. The grommet surface may have an arc-shaped structure, that is, the projection on the horizontal plane is arc-shaped. The grommet surface facilitates the reception of manual operations, and the finger shape conforms to ergonomic relationships. In some embodiments, the first buckle portion 6013 is a pair of sheet-like 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-like structure decreases from the root portion to the free end. The first elastic arm 6011 may be formed from a general elastic material, such as plastic or organic elastic material, as a whole.
[0065] In some embodiments, as shown in FIG. 8, which is an enlarged schematic view of the first locking member 701 at A in FIG. 3A, a first locking member 701 is provided at a position on the inner wall of the accommodating cavity 200 that substantially corresponds to the first locking member 601. The first locking member 601 cooperates with the first locking member 701 to be locked. In some embodiments, the first locking member 701 is a pair of through holes, and the free end of the sheet-like structure is inserted into the through holes to be locked.
[0066] In some embodiments, a first recess 206 is provided at a position substantially corresponding to the first grommet recess 603 on the inner wall of the receiving cavity, and the pair of through holes are provided on both sides of the first recess 206. Locking is achieved when the first locking member 601 enters the through hole, and unlocking is achieved when a finger is inserted through the first recess 206 and a force is applied to pull the first locking member 601 out of the through hole. The cooperation between the first recess 206 and the first grommet recess 603 makes the access operation by the finger easier and more convenient.
[0067] In some embodiments, as shown in FIG. 9A, the locking mechanism further includes a second locking mechanism 620. The second locking mechanism 620 includes a second grommet recess 605 and a second locking member 602. The second grommet recess 605 forms a notch, for example an arc-shaped or square-shaped notch, on the inside along approximately the midline position of the top cover second part 3022, which is easy for fingers to reach for snap operation. The second locking member 602 is located below the second grommet recess 605, and the second grommet recess 605 provides enough space for fingers to control the second locking member 602, and the second locking member 602 elastically moves inward under the action of an external force. Specifically, the second locking member 602 includes a second elastic arm 6021, a second grommet portion 6022, and a second buckle portion 6023. Here, the second elastic arm 6021 is located below the second grommet recess 605, and the second elastic arm 6021 includes two symmetrical parts, and each second elastic arm 6021 first extends along the opening direction of the second grommet recess 605, then extends along the direction of the edge of the top cover, and then extends along the edge direction of the second grommet recess 605. Here, the opening direction of the second grommet recess 605 is the A direction from the center of the top cover to the outside, as shown in FIG. 9A, and in this embodiment, it is also the rear of the dust box top cover, and the two parts of the second elastic arm 6021 are symmetrically connected to each other in a substantially two "box" shaped structure. The second grommet part 6022 is connected to the two parts of the second elastic arm 6021 that are symmetrically arranged. The second grommet portion 6022 is provided above the two second elastic arms, and as shown in Fig. 9B and Fig. 9C, which is an enlarged view of the second grommet portion in Fig. 9BC, the bottom of the second grommet portion 6022 is provided with a bottom surface 60221 that protrudes substantially outward and a grommet surface 60222 that extends upward along the bottom surface, and extends to a position where the grommet surface is substantially flush with the top cover. The grommet surface may have a circular arc structure, and the grommet surface facilitates receiving manual operation and is convenient for fingers to apply action force.In some embodiments, the second grommet portion 6022 is integrally formed with the symmetrically arranged second elastic arm 6021, and the second buckle portion 6023 is provided on a lateral extension portion of the second elastic arm. The second buckle portion 6023 is symmetrically arranged along both sides of the pair of second elastic arms 6021, and is, for example, a protrusion or sheet-like structure extending along the A direction. In some embodiments, each of the second buckle portions 6023 has a groove extending inward from an end of the second buckle portion 6023, and the groove can prevent the second buckle portion from being too deformed after the entire second buckle portion is molded and cooled, making it difficult to snap. In some embodiments, the second locking member 602 further includes a symmetrically arranged connecting member 6024. The connecting member 6024 is substantially planar, and one end of the second elastic arm 6021 is connected to one surface of the connecting member 6024, and the other surface of the connecting member 6024 is connected to and fixed on an end surface of a support structure. The second grommet portion 6022 is exposed from the second grommet recess portion 605 in the X direction, and when unlocking, a finger reaches the second grommet recess portion 605 and presses the second grommet portion 6022, applying a force to the inside of the dust box along the X axis and elastically contracting the second buckle portion 6023 inward. The second buckle portion 6023 pops up from the bottom of the second locking member 702 to achieve unlocking. The second elastic arm 6021 as a whole is generally formed of an elastic material such as plastic or an organic elastic material.
[0068] In some embodiments, as shown in FIG. 10, which is an enlarged view of the second locking member 702 in B of FIG. 3B, a second locking member 702 is provided at a location on the inner wall of the receiving cavity 200 that approximately corresponds to the second locking member 602, and the second locking member 602 cooperates with the second locking member 702 to be locked. The second locking member 702 is a pair of protrusions, and the second buckle portion 602 extends to the bottom of the second locking member 702 to achieve locking. The protrusions may be flat, cylindrical, rectangular, etc., but are not limited thereto, as long as they can be engaged with the second buckle portion.
[0069] In some embodiments, a second recess 207 is provided at a position on the underside of the second cavity 202 that substantially corresponds to the second grommet recess 605, and the pair of protrusions are provided at the same height on the rear wall of the second cavity 202 and located above the second recess 207. The second recess 207 is configured to be accommodated avoiding the second locking member 602 when the dust box 300 is placed in the receiving cavity 200, and the entire dust box can be well placed in a predetermined position in the receiving cavity 200.
[0070] In some embodiments, the top cover includes a first portion covering the receiving portion and a second portion extending outward from the receiving portion, and the second grommet recess 605 and the second locking member 602 are located in the second portion of the top cover. A support structure 3023 configured to support the second portion of the top cover is provided below the second portion of the top cover. The second locking member 602 is provided on the support structure 3023, and as shown in FIG. 4, the symmetrically arranged support structures 3023 form a space compressed inward in the X direction, and when the second elastic arm 6021 is connected to the symmetrically arranged support structures 3023, a sufficient elastic space is ensured to respond to an applied inward acting force.
[0071] In the dust box lock structure described in the above embodiment, the lock structure is symmetrically arranged in the front and rear direction of the dust box top cover, and the lock can be released by applying force to the two elastic structures in the front and rear of the dust box with one hand, which avoids one side being unlocked and the dust box on one side popping up, causing the dust box to tilt. At the same time, the elastic structure is simple, and the elastic unlock can be achieved by forming the elastic arm with an elastic material, so that the damage of the complex unlocking device such as a spring can be avoided.
[0072] In some embodiments, as shown in FIG. 4, the second locking mechanism 620 includes at least one first magnetic attraction module 604, and the first magnetic attraction module 604 is disposed between the second portion of the top cover and the support structure. As shown in FIG. 3A, the receiving cavity includes at least one second magnetic attraction module 606 configured to cooperate with the first magnetic attraction module 604 to be attracted and locked. In the application process, the first locking member 601 corresponding to the dust box can be retracted by pressing the first locking member 601 and the second grommet recessed portion 605 with the hand, and the dust box is put into the receiving cavity and released, and the first buckle portion 6013 of the first locking member 601 automatically pops up and is inserted into the first locking member 701, and the first magnetic attraction module 604 is attracted to the second magnetic attraction module 606, thereby achieving the locking of the dust box. The locking structure is simple and easy to operate, and is convenient for realizing the locking of the dust box.
[0073] In some embodiments, the second locking mechanism 620 as described above may be an embodiment including a second grommet recess 605 and a second locking member 602, an embodiment including a first magnetic attraction module 604, or an embodiment including both, but is not limited to these.
[0074] The dust box of the existing automatic cleaning device needs to be equipped with a replaceable dust box filter, and the conventional filter generally uses a hard frame made of plastic or metal, a cascading filter medium is put into the frame, and a dot adhesive is used to connect and seal the frame and the periphery of the filter medium, and then a sealing strip is attached on the frame to seal the gap between the filter and the dust box. Therefore, the conventional dust box filter part has a complicated structure, the filter installation process is complicated, there is a waste of labor and cost, and the sealing adhesive is not economical and environmentally friendly.
[0075] In this regard, an embodiment of the present application provides an automatic cleaning device, comprising: a moving platform configured to automatically move on an operation surface, including a receiving cavity; and a cleaning module including a dust box. The dust box is detachably mounted in the receiving cavity. The dust box includes a dust box filter. The dust box filter is applied to the dust box of the automatic cleaning device, and the assembly process of the dust box filter is simplified. This embodiment has some simplified structural features compared with the above embodiment, and the same structure has the same technical effect, and some technical effects are omitted here. As shown in FIG. 11 and FIG. 12, the dust box filter 500 includes a soft rubber frame 501, and the soft rubber frame includes at least one soft rubber protrusion for sealing the assembly gap with the dust box during the assembly process, and a filter material 502 sleeved in the soft rubber frame 501. Here, the soft rubber frame 501 is non-detachably connected to the filter material 502. In some embodiments, the process of non-detachably connecting the soft rubber frame 501 and the filter media 502 includes an overmolding injection process. The filter media can be pre-sleeved in the frame and a rubber sleeve can be sleeved onto the sleeved frame combination to integrally form the desired sealing protrusions. Alternatively, a two-shot injection molding process can be used to first inject the hard rubber frame body, sleeve the filter media onto the frame body, and then inject the soft rubber to form the inner and outer sealing protrusions.
[0076] The soft rubber frame 501 may be rectangular, square, elliptical, circular, polygonal, etc., and the structure is not limited thereto. In some embodiments, as shown in Fig. 11 and Fig. 12, the soft rubber frame 501 is rectangular, and the soft rubber frame of the rectangular structure includes two first side walls 50111 and two second side walls 50113 arranged opposite each other. The soft rubber protrusions include a first protrusion 5011 distributed on the outer circumferential surface of one of the first side walls 50111 and a second protrusion 5015 distributed on the outer circumferential surface of the other first side wall 50111, and a pair of first side walls 50111 and a pair of second side walls 50113 are formed around the rectangular structural frame, and a filter medium is sleeved in the rectangular structural frame.
[0077] In some embodiments, the first protrusion 5011 and the second protrusion 5015 are continuous protrusion structures, for example, the first protrusion 5011 and the second protrusion 5015 extend continuously from one end to the other end of the outer circumferential surface of the first side wall 50111. Because the first protrusion 5011 and the second protrusion 5015 are soft rubber structures, when the dust box filter is assembled into the dust box, the first protrusion 5011 and the second protrusion 5015 are pressed to directly seal between the dust box filter 500 and the second opening 3012 of the dust box, and the second opening 3012 of the dust box is fully contacted and sealed with the inner wall extending along a substantially horizontal direction, which replaces the traditional step of sealing through a sealing strip after the dust box filter is assembled into the dust box.
[0078] In some embodiments, as shown in FIG. 14, at least one of the first protrusion and the second protrusion is a reversible buckle structure. The reversible buckle structure is configured to seal the assembly gap between the soft rubber frame and the dust box and prevent the dust box filter from falling off from the dust box. For example, the reversible buckle structure is an arc-shaped structure, and the arc-shaped structure is inclined toward the opposite side to the assembly direction of the dust box filter. The reversible buckle structure makes it convenient for the dust box filter to extend into the assembly opening of the dust box with friction, incline toward the opposite side to the assembly direction, and then be pressed and sealed between the dust box filter and the dust box during the assembly process of the dust box filter.
[0079] In some embodiments, the second side wall of the soft rubber frame further includes at least one third protrusion 5012. The third protrusions 5012 are distributed on the outer circumferential surface of at least one second side wall 50113 of the frame structure. The third protrusions 5012 may be a distributed multi-protrusion structure. In one embodiment, the third protrusions 5012 are distributed on the outer circumferential surface of the two second side walls 50113 of the frame structure, and when the dust box filter is assembled to the dust box, the third protrusion 5012 on the outer circumferential surface of one second side wall 50113 of the frame structure has a slightly long structure, and extends into the recess of the dust box side wall to function as a fastener and prevent the dust box filter from falling off. During the assembly of the dust box filter, the slightly long third protrusion 5012 is first inserted into the recess of the dust box side wall, and rotated around the third protrusion 5012, and then the other side of the dust box filter is mounted to the dust box. The third protrusions 5012 distributed on the outer peripheral surface of another second side wall 50113 of the frame structure have a smoother structure, and when the dust box filter is assembled to the dust box, the third protrusions 5012 on the side are interlocked with the elastic structure 5013 of the side wall of the dust box by interference fit, so as to prevent the dust box filter from falling off. Here, the elastic structure 5013 is substantially an S-structure, and includes an inner recess for accommodating the third protrusion 5012 and an outer protrusion interlocked with the third protrusion 5012. The outer protrusion moves elastically under the action of an external force to interlock with the third protrusion 5012. Figure 15 shows the installation structure of the dust box filter when viewed from the bottom end of the dust box. In some embodiments, as shown in Figures 13A and 13B, the soft rubber frame has a first rib position 510, which is provided on the outer circumferential surface of the second side wall and is configured to prevent the dust box filter from being installed too deeply or too shallowly in the dust box, resulting in assembly failure. During the process of installing the dust box filter in the dust box, after 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, which can prevent the filter from further stretching inward and prevent the dust box filter from being installed too deeply in the dust box.At the same time, during the assembly process, if the first rib position 510 is not abutted against the pillow position 5014 of the dust box side frame, as shown in FIG. 15, it is considered that the dust box filter is not assembled in the specified position, so that the dust box filter can be prevented from being installed too shallowly in the dust box.
[0080] In some embodiments, as shown in Figures 13A and 13B, the soft rubber frame further includes an anti-mis-installation protrusion 509, which is provided on the outer circumferential surface of the second side wall and is configured to prevent the dust box filter from being installed in the opposite direction. A recess is provided at a position corresponding to the anti-mis-installation protrusion 509 of the dust box, and when the dust box filter is normally installed, the anti-mis-installation protrusion 509 enters the recess and the dust box filter is normally assembled, and when the dust box filter is installed in the opposite direction, the dust box filter cannot be assembled due to the anti-mis-installation protrusion 509 because there is no recess on the other side of the dust box, which serves to prevent the installation of the dust box filter in the opposite direction.
[0081] In some embodiments, as shown in Figures 3A and 3B, the receiving cavity 200 includes a first cavity 201 and a second cavity 202. The first cavity 201 and the second cavity 202 are sequentially arranged adjacent to each other in the forward direction of the automatic cleaning device, and the depth of the first cavity 201 is deeper than that of the second cavity 202. A dust suction port 203 is provided at the bottom of the front wall of the first cavity 201, an air outlet 208 is provided at the rear wall of the connection between the first cavity 201 and the second cavity 202, a fan is accommodated in the lower space of the second cavity 202, and an exhaust port 204 is provided at the rear wall of the moving platform 100. Under the suction force of the fan, dust enters the dust box 300 through the dust suction port 203, and the airflow is filtered by the dust box filter and then exhausted through the exhaust port 204. Here, the air outlet 208 is provided with a grill structure.
[0082] As shown in Figures 11 and 12, the soft rubber frame further includes a sealing inner lip 507. The sealing inner lip 507 is provided on the first end surface 50116 of the soft rubber frame 501 to surround the filter medium 502, and is configured to realize a sealing fit between the dust box filter and the assembly surface 30121 of the second opening 3012 of the dust box. As shown in Figure 14, the assembly surface 30121 of the second opening 3012 of the dust box is provided on the side close to the inner wall of the dust box in the second opening, has a substantially planar structure, and is abutted against the first end surface 50116 of the soft rubber frame 501 to be assembled to the soft rubber frame. The sealing outer lip 506 is provided on the second end surface 50115 of the soft rubber frame 501 to surround the filter medium 502, and is configured to seal the edge of the dust box filter and the air outlet 208 of the receiving cavity 200. The sealing inner lip 507 and the sealing outer lip 506 are higher than the first end surface 50116 or the second end surface 50115 where they are located, and after being assembled in a predetermined position, the sealing inner lip 507 is pressed between the dust box filter and the assembly surface of the dust box. Because the sealing inner lip 507 is a soft material, it seals the dust box filter with the assembly surface of the dust box under the action of pressing force. When the dust box is assembled into the automatic cleaning device, the sealing outer lip 506 of the dust box filter is pressed between the dust box filter and the outside of the grill of the air outlet 208 of the receiving cavity 200, and seals the dust box filter with the assembly surface of the fan bracket. As shown in Figures 3A and 3B, the side wall connecting the first cavity 201 and the second cavity 202 constitutes the assembly surface of the fan bracket, the fan is installed below the second cavity 202, and the grill-type air outlet 208 is installed on the side wall connecting the first cavity 201 and the second cavity 202.The sealing inner lip 507 and the sealing outer lip 506 provided on the soft rubber frame 501 realize the sealing engagement between the inner end face of the dust box filter 500 and the assembly surface of the air outlet of the dust box, and between the outer end face of the dust box filter 500 and the grill outer surface of the air outlet of the receiving cavity 200, thereby eliminating the traditional cumbersome step of adding sealing strips on the inside and outside of the dust box filter to meet the air flow path sealing requirements. The soft rubber frame 501, as a carrier, also includes the sealing inner lip 507 and the sealing outer lip 506, which have a certain degree of flexibility as a sealing structure, so that the contact, sealing and engagement are tighter, fit more satisfactorily, and the sealing effect is stronger, which can ensure the airtight performance of the entire air flow path, and plays a role of better protecting the functions of the cleaning device such as dust suction and dust discharge by negative pressure.
[0083] In some embodiments, as shown in Figures 11 and 12, the soft rubber frame further includes a step surface 503, which extends outward along the second end surface 50115 of the soft rubber frame 501, and the step surface 503 and the side wall of the soft rubber frame 501 form a step structure, which is configured to prevent the dust box filter from being installed too deeply in the dust box. During the assembly process, as shown in Figure 14, when the dust box filter enters the dust box assembly opening, the step surface 503 abuts against the outer edge of the dust box assembly and is locked with the outer edge of the dust box, thereby preventing the dust box filter from being installed too deeply in the dust box.
[0084] In some embodiments, as shown in Fig. 11, the soft rubber frame further includes a magnetic device mounting hole 504, which is provided on the second end surface 50115 of the soft rubber frame 501 and is configured to be attached to a magnetic device to ensure that the dust box filter is mounted in a predetermined position. The magnetic device can be a magnet or other electromagnetic element, and an inductive magnetic device is mounted in the magnetic device mounting hole 504. The magnetic device mounting hole 504 has a sufficient depth so that the magnetic device can be mounted in a fixed position inside the filter, and when the entire filter is mounted in the fixed position, it can be detected by a Hall sensor to ensure that the filter is mounted in a predetermined position.
[0085] In some embodiments, as shown in Figure 11, the soft rubber frame further includes a second rib location 5041, which is disposed around the magnetic device mounting hole and configured to prevent liquid from entering the magnetic device mounting hole. The second rib location 5041 tightly cradles the outer end of the magnetic device outside the magnetic device mounting hole 504, thereby preventing the magnetic device from rusting and becoming damaged. The second rib location 5041 may be a soft rubber material, which further cradles the magnetic device when pressed.
[0086] In some embodiments, as shown in Figure 11, the soft rubber frame further includes a grommet 505, which is disposed at a position extending outward from the step surface 503 and configured to facilitate removal of the dust box filter. The shape and structure of the grommet 505 are not limited and may be semicircular, square, rectangular, etc.
[0087] In some embodiments, the soft rubber frame further includes a hollow structure 508, disposed in a first sidewall and / or a second sidewall of the frame, configured to reduce the overall weight of the frame, as shown in Figure 12. The hollow structure 508 may be a plurality of inwardly recessed pin holes, although the shape of the pin holes is not limited and may be circular, square, rectangular, irregular, etc.
