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

[0029] 1 and 2 are schematic structural diagrams of an automatic cleaning device according to an exemplary embodiment. As shown in 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 man-machine interactive system 170.

[0030] The mobile platform 100 is configured to move automatically in a target direction on an operating surface. The operating surface may be a surface to be cleaned by an automatic cleaning device. In some embodiments, the automatic cleaning device may be a mopping robot, where the automatic cleaning device works on a floor surface, and the floor surface is the operating surface. Or, the automatic cleaning device may be a window cleaning robot, where the automatic cleaning device works on a glass exterior surface of a building, and the glass is the operating surface. Or, the automatic cleaning device may be a pipe cleaning robot, where the automatic cleaning device works on an interior surface of a pipe, and the interior surface of the pipe is the operating surface. Purely for purposes of illustration, the mopping robot is used as an example in the present disclosure.

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

[0032] The sensing system 120 includes a positioning device 121 located above the mobile platform 100, a buffer 122 located in the front portion 111 of the mobile platform 100, a cliff sensor 123 located at the bottom of the mobile platform, and sensing devices such as 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.

[0033] In order to more clearly describe the behavior of the automatic cleaning device, the following directions are defined, i.e., the automatic cleaning device can move on the floor surface by various combinations of movements about three mutually perpendicular axes defined by the moving platform 100: the lateral axis Y, the front-rear axis X, and the central vertical axis Z. The forward driving direction along the front-rear axis X is designated as "forward", and the rear driving 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 around the Y axis. When the front part of the automatic cleaning device is tilted upward and the rear part is tilted downward, it is called "pitch up", and when the front part of the automatic cleaning device is tilted downward and the rear part is tilted upward, it is called "pitch down". In addition, the automatic cleaning device can rotate around the Z axis. When the automatic cleaning device is tilted to the right of the X axis at the front of the automatic cleaning device, it is called "right turn", and when the automatic cleaning device is tilted to the left of the X axis, it is called "left turn".

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

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

[0036] 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.

[0037] 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.

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

[0039] The control system 130 is provided on a circuit board in the mobile platform 100 and includes a central processing unit, an application processor, etc., which communicates with a non-transitory memory such as a hard disk, a flash memory, a random access memory, etc., and the application processor receives the environmental information sensed by the multiple sensors from the sensing system 120, the obstacle information fed back from the positioning device, etc., 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 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.

[0040] Specifically, the control system 130 combines distance information and speed information fed back from the buffer 122, cliff sensor 123, and sensing devices such as ultrasonic sensor, infrared sensor, magnetometer, accelerometer, gyroscope, odometer, etc. to comprehensively determine the current working state of the vacuum cleaner, such as crossing a threshold, riding on a carpet, being located on a cliff, being caught on the upper or lower side, 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 obtain a better user experience. Furthermore, 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.

[0041] 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 travel across the floor surface. As shown in FIG. 2, the drive system 140 includes a drive wheel assembly 141, and the drive system 140 can simultaneously control the left and right wheels, and in order to more precisely control 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 and right drive wheel assemblies are symmetrically arranged along the horizontal axis defined by the mobile platform 100.

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

[0043] The energy system 160 includes a rechargeable battery such as a nickel-metal hydride battery and 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 through a charging electrode provided on the side or under the main body.

[0044] The man-machine interactive system 170 includes keys on a host panel, which are available for the user to select functions, 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, the mobile phone client can display a map of the environment in which the device is installed and the location of the device to the user, providing the user with more abundant and convenient function items.

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

[0046] The dry cleaning module 151 includes a roller brush, a dust box, a fan, and an air outlet. The roller brush, which 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 a vacuum cleaner is characterized by the dust pickup efficiency (DPU), which is affected by the structure and material of the roller brush, 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 parts, and the type and power of the fan, and is a complex system design issue. Compared with ordinary plug-in dust suction devices, the improvement of dust removal capacity is of great significance for automatic cleaning devices with energy limitations. This is because the improvement of 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 battery less frequently. More intuitively and importantly, the improvement of dust removal ability is the most obvious and important user experience, and users can directly conclude whether the machine cleans cleanly or wipes cleanly. The dry cleaning module may further include a side brush 152 on the 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.

[0047] As a selectable cleaning module, the automatic cleaning device may further include a wet cleaning module, configured to clean at least a portion of the operating surface using a wet cleaning method, 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.

[0048] The casing layout frame structure of the existing automatic cleaning device is complex, has a large number of parts, requires long assembly labor, and is a cumbersome process. Adding a top flap and flip mechanism to the automatic cleaning device and designing a top casing decorative part on the top flap, etc., increases the cost. Although the top casing decorative part and the top flap can fulfill the functions of covering dirty items and protecting internal parts, it makes the structure of the entire machine complex, increases the cost, and affects the design space of the dust box under the top flap, etc.

[0049] In this regard, the embodiments of the present disclosure provide an automatic cleaning device without a flip cover, which can simplify unnecessary components of the automatic cleaning device while expanding the design space of the dust box and its containing cavity, and achieve the same technical effects with the same structure, and some technical effects will not be repeated in this specification. Specifically, the present disclosure provides an automatic cleaning apparatus, the automatic cleaning apparatus including a moving platform 100 configured to automatically move on an operating surface as shown in FIG. 3, the moving platform 100 including a storage cavity 200, in some embodiments, the storage cavity 200 is disposed on a rearwardly biased side in the forward movement direction of the automatic cleaning apparatus, the storage cavity 200 including a first cavity 201 and a second cavity 202, the dry cleaning module 151 including a dust box 300, the dust box 300 being removably assembled to the storage cavity 200, wherein the first cavity 201 and the second cavity 202 are sequentially arranged adjacent to each other in the forward movement direction of the automatic cleaning apparatus, and the depth of the first cavity 201 is greater than the depth of the second cavity 202. The first cavity 201 and the second cavity 202 are arranged adjacent to each other in the forward direction of the automatic cleaning device, and a larger part of the dust box in terms of volume and weight is located closer to the center of the automatic cleaning device, so that the dust box is more stably arranged in the accommodating cavity 200, making the center of gravity of the entire cleaning device more stable, and making it more stable during the processes of moving forward, turning, crossing obstacles, etc., and not easily falling over. At the same time, the dust box accommodating part and the dust box top cover are integrated into one structure, and the dust box top cover functions as a part of the top surface of the moving platform and is flush with the other parts of the top surface of the moving platform. This eliminates the flip cover structure of the conventional cleaning device, and allows the dust suction port located approximately in the center of the bottom of the cleaning device to be easily and directly aligned with the dust box, allowing dust to enter the dust box directly from the dust suction port, reducing the movement of dust entering the inside of the device, and avoiding dust pollution to the inside of 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, an air outlet 208 is provided at the rear wall of the connection point between the first cavity 201 and the second cavity 202, the air outlet 208 has a grill structure, a fan is accommodated in the lower space of 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 air outlet 204 is provided at the rear wall of the moving platform 100, and 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 discharged through the air outlet 204.

[0050] In some embodiments, the dust box 300 includes a receiving part 301 and a top cover 302 above the receiving part 301, and the top cover is fixedly connected to the receiving part. The fixed connection method includes, but is not limited to, gluing, welding, integral molding, bolting, fastening, etc. The receiving part is used to receive the dust sucked through the dust suction port 203, and the appearance of the receiving part is approximately the same as the first cavity 201.

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

[0052] Typically, the accommodating part 301 of the dust box 300 has a first opening 3011 at the front side of the dust box, the first opening 3011 is aligned with the dust inlet 203, the accommodating part 301 has a second opening 3012 at the rear side of the dust box, the filter 500 is installed at the second opening 3012, and the second opening 3012 is connected to the air outlet 208. The filter 500 and the box body of the dust box 300 are detachably connected, so that the filter can be easily detached and washed. Here, the front side refers to one 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 side opposite to the forward direction of the automatic cleaning device in the X direction.

[0053] In some embodiments, the top cover 302 includes a first portion 3021 covering the accommodating portion 301 and a second portion 3022 protruding from the accommodating portion 301 and extending outward, and 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 is approximately consistent with the top end portion of the first cavity and the structure of the second cavity, so that the dust box 300 is stably installed in the accommodating cavity 200 and the dust box is prevented from shaking due to the 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, and 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 selectivity of the volume of the dust box is improved, and a specific size can be set as required, which can reduce the molding cost without affecting the overall opening size of the accommodating cavity.

[0054] In some embodiments, the first portion 3021 of the top cover 302 includes an edge 30211 extending outward from the edge contour of the receiving portion. The receiving cavity 200 includes a step 205 extending around the top edge of the receiving cavity, the step 205 being configured to receive at least a portion of the edge 30211 and at least a portion of the second portion outer edge, so that the top surface of the top cover is substantially flush with the top surface of the moving platform. The step 205 extending around the top edge of the receiving cavity of the receiving cavity 200 can entirely receive the edge of the top cover 302, so that the top cover 302 is received in the receiving cavity 200 in a substantially seamless manner, which can prevent foreign objects from falling directly into the edge seam of the dust box and getting the dust box stuck, and at the same time ensure the appearance of the top cover as the top surface of an automatic cleaning device.

[0055] In some embodiments, a support structure 3023 configured to support the second part 3022 of the top cover 302 is provided below the second part 3022 of the top cover 302. Optionally, the support structure 3023 is integrally molded with at least a part of the receiving part 301, so as to increase the support force of the support structure 3023 on the second part 3022 of the top cover 302 and effectively prevent damage thereto. The support structure 3023 may include, but is not limited to, an arc-shaped structure and a linear structure. In one embodiment, for example, the support structure 3023 is two symmetrically arranged arc-shaped structures that are approximately consistent with the outer edge contour of the second part 3022 of the top cover 302.

[0056] In some embodiments, a groove 2021 is provided on the underside of the second cavity 202, the groove 2021 approximately conforming to the contour of the support structure 3023, and when the second part of the top cover is received in the second cavity, the support structure 3023 is received in the groove 2021 and the upper surface of the top cover 302 is approximately horizontal.

[0057] In some embodiments, the top cover is symmetrically arranged along the central axis of the forward direction of the automatic cleaning device. In some embodiments, as shown in Figures 6a to 6h, the shape of the top cover is at least one of a D-shape, a rectangle, a square, a circle, an ellipse, a triangle, a square, a pentagon, a hexagon, a heptagon, or an octagon, or a combination thereof. The symmetrical arrangement allows the appearance of the device to be maintained without being covered by an outer cover, and also makes it convenient to install and remove the dust box.

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

[0059] The above embodiment relates to a dust box of an automatic cleaning device and its mounting structure, in which an accommodating cavity is provided on the rear side of the forward direction of the automatic cleaning device, the accommodating cavity 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 upper surface of the top cover of the dust box is approximately flush with the upper surface of the moving platform, thereby simplifying the top surface structure of the automatic cleaning device, reducing production costs, and at the same time increasing the design space of the accommodating cavity.

[0060] Existing automatic cleaning devices are provided with a pop-up dust box and a non-pop-up dust box, a pop-up dust box top flap and a flip mechanism, and when attaching or detaching the dust box, the top flap must be opened and the dust box must be pressed to pop up the dust box, and this embodiment requires a complex dust box pop-up mechanism, which includes multiple parts such as a spring, and the elasticity of the spring decreases with repeated use, making it impossible for the dust box to pop up smoothly, and the dust box may not pop up normally due to many other parts, which has a negative impact on use. Non-pop-up dust boxes often adopt a complex locking 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, making the overall usability poor.

[0061] In this respect, the embodiment of the present disclosure provides an automatic cleaning device without a flip cover, which can simplify unnecessary elements of the automatic cleaning device while facilitating smooth removal of the dust box, and the embodiment will briefly describe some structural features compared with the above embodiment, but the same structure has the same technical effect, and some technical effects will not be repeated in this specification. Specifically, as shown in Figures 1 to 5 and 7, the automatic cleaning device is configured to move automatically on the 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, and the dust box 300 is removably assembled in the storage cavity 200, and the dust box includes a storage part 301, a top cover 302 above the storage part, and a locking mechanism.

Here, the first elastic arm 6011 extends upward from the bottom of the first grommet recess 603. The first grommet portion 6012 is provided at an end portion extending above the first elastic arm 6011. The first fastening 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 above the first elastic arm 6011 in the lateral direction. The first grommet portion 6012 has a bottom surface that protrudes substantially outward and a grommet surface that extends upward along the bottom surface. The grommet surface extends to a position substantially flush with the top cover. The grommet surface may have an arc-shaped structure, that is, the projection on the horizontal plane is arc-shaped. The grommet surface facilitates the reception of manual operation, and the finger shape conforms to ergonomic relationships. In some embodiments, the first fastening portion 6013 is a pair of sheet structures symmetrically provided along both sides of the first elastic arm 6011. To facilitate the insertion of the first locking member 701, the width of the sheet structure decreases from the root portion to the free end portion. The first elastic arm 6011 may be formed from a general elastic material, such as plastic or an organic elastic material, as a whole.

[0063] In some embodiments, as shown in FIG. 8, FIG. 8 is an enlarged schematic view of the first locking member at A in FIG. 3a. A first locking member 701 is provided at a location substantially corresponding to the first locking member 601 on the inner wall of the accommodation cavity 200. 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 portion of the sheet structure is inserted into the through holes and locked.

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

[0065] In some embodiments, as shown in FIG. 9a, the locking mechanism further includes a second locking mechanism 620, the second locking mechanism 620 includes a second grommet recess 605 and a second locking member 602, the second grommet recess 605 is formed with a notch, for example a circular or rectangular notch, on the inner side along approximately the midline position of the top cover second part 3022, which is easy to reach with fingers for snap operation, the second locking member 602 is located below the second grommet recess 605, 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 fastening portion 6023, where the second elastic arm 6021 is located below the second grommet recess 605, and the second elastic arm 6021 includes two symmetrical parts, where 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, where the opening direction of the second grommet recess 605 is the direction A from the center of the top cover to the outside, as shown in FIG. 9a, and is also the rear direction of the dust box top cover in this embodiment, and the two parts of the second elastic arm 6021 are symmetrically connected to each other in an approximately two “box” shaped structure, and the second grommet portion 6021 is connected to the second grommet portion 605 in an approximately two-sided “box” shaped structure. 22 is connected to the second elastic arm 6021 of two parts arranged symmetrically, specifically, the second grommet portion 6022 is arranged above the two second elastic arms, as shown in Fig. 9b and Fig. 9c, Fig. 9c is an enlarged view of the second grommet portion in C of Fig. 9b, the bottom of the second grommet portion 6022 is provided with a bottom surface 60221 protruding almost outward and a grommet surface 60222 extending upward along the bottom surface, the grommet surface extends to a position where it is almost flush with the top cover, the grommet surface may have an arc-shaped structure, the grommet surface facilitates receiving manual operation and is convenient for fingers to apply acting force, optionally, the second grommet portion 6022 is integrally molded with the second elastic arm 6021 arranged symmetrically, and the second fastening portion 6023 is provided on the horizontal extension portion of the second elastic arm. The second fastening portions 6023 are provided symmetrically along both sides of the pair of second elastic arms 6021, and are, for example, protrusion or sheet structures extending along the A direction. As an optional embodiment, each of the second fastening portions 6023 has a groove extending inward from an end of the second fastening portion 6023, and the groove can prevent the second fastening portion from deforming significantly after the entire portion is molded and cooled, which makes it difficult to snap the fastening portion.Optionally, the second locking member 602 further includes a symmetrically arranged connecting member 6024, the connecting member 6024 is substantially planar, one end of the second elastic arm 6021 is connected to one surface of the connecting member 6024, and the other surface of the connecting member 6024 is connected to and fixed on the end surface of the support structure. The second grommet portion 6022 is exposed from the second grommet recess 605 in the X direction, and during unlocking, a finger reaches the second grommet recess 605 and presses the second grommet portion 6022, exerting a force on the inside of the dust box along the X axis to make the second fastening portion 6023 elastically contract inward, and the second fastening 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 made of an elastic material such as plastic or organic elastic material.

[0066] In some embodiments, as shown in Fig. 10, Fig. 10 is an enlarged view of the second locking member 702 in Fig. 3b B, the second locking member 702 is provided at a location on the inner wall of the receiving cavity 200 that corresponds approximately to the second locking member 602, and the second locking member cooperates with the second locking member to lock. The second locking member is a pair of protrusions, and the second catch 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 catch.

[0067] In some embodiments, a second recess 207 is provided at a position on the underside of the second cavity 202 that corresponds substantially to the second grommet recess 605, and the pair of protrusions are provided equidistantly on the rear wall of the second cavity 202 and located above the second recess 207. The second recess 207 is configured to accommodate the second locking member 602 when the dust box 300 is placed in the receiving cavity 200, so that the entire dust box can be well placed in a predetermined position in the receiving cavity 200.

[0068] In some embodiments, the top cover includes a first portion covering the receiving portion and a second portion protruding from the receiving portion and extending outward, and the second grommet recess 605 and the second locking member 602 are located in the second portion of the top cover. A support structure 3023 configured to support the second portion of the top cover is provided below the second portion of the top cover, and the second locking member 602 is provided on the support structure 3023, and the symmetrically provided support structures 3023 form an inward compression space in the X direction, as shown in FIG. 4, 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 acting force.

[0069] In the dust box lock structure described in the above embodiment, the lock structure is symmetrically arranged in the front and rear directions 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 and tilting the dust box. 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, which avoids the risk of a complex unlocking device such as a spring being easily damaged.

[0070] In some embodiments, as shown in FIG. 4, the second locking mechanism 620 includes at least one first magnetic attraction module 604, and the first magnetic attraction module 604 is disposed between the second part 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 recess 605 with the hand, and the dust box is put into the receiving cavity and released, the first catch 6013 on the first locking member 601 automatically pops up and is inserted into the first locking member 701, the first magnetic attraction module 604 is attracted to the second magnetic attraction module 606, and the locking of the dust box is achieved, and the locking structure is simple and easy to operate, which is convenient to realize the locking of the dust box.

[0071] In some embodiments, the second locking mechanism 620 as described above may be an embodiment including a second grommet recess 605 and a second locking member 602, an embodiment including a first magnetic attraction module 604, or an embodiment including both, but is not limited to these.

[0072] The dust box of the existing automatic cleaning device needs to be equipped with a replaceable dust box filter, and the existing filter generally uses a hard frame made of plastic or metal, a cascading filter medium is put into the frame, and the frame and the periphery of the filter medium are connected and sealed with a dot adhesive, and then a sealing strip is attached on the frame to seal the gap between the filter and the dust box. Therefore, the structure of the existing dust box filter part is complicated, the filter installation process is complicated, there is a waste of labor and cost, and the adhesive for sealing is not economical and environmentally friendly.

[0073] In this regard, an embodiment of the present disclosure provides an automatic cleaning device, the automatic cleaning device is configured to move automatically on an operating surface, and includes a moving platform including a receiving cavity, and a cleaning module including a dust box, the dust box is detachably mounted in the receiving cavity, the dust box includes a dust box filter, and 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, and some structural features of this embodiment are simplified compared with the above embodiment, and the same structure has the same technical effect, and some technical effects are omitted here. Specifically, as shown in Figure 11 and Figure 12, the dust box filter 500 includes a soft rubber frame 501, the soft rubber frame includes at least one soft rubber protrusion 5011 for sealing the assembly gap with the dust box during the assembly process, and a filter material 502 fitted in the soft rubber frame 501, and the soft rubber frame 501 is non-detachably connected to the filter material 502. The specific process of non-detachably connecting the soft rubber frame 501 and the filter material 502 includes an overmolding injection process, in which the filter material is pre-fitted in the frame, and a rubber sleeve is fitted to the fitted frame combination to integrally form a number of desired sealing protrusions. Alternatively, a two-shot injection molding process may be used to first inject the hard rubber frame body, and then the filter material is fitted into the frame body, and then the soft rubber is injected to form the inner and outer sealing protrusions.

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

[0075] 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 of the soft rubber frame. 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 in contact with the inner wall extending along the approximately horizontal direction and sealed, which replaces the traditional step of sealing through a sealing strip after the dust box filter is assembled into the dust box.

[0076] In some embodiments, as shown in Fig. 14, at least one of the first protrusion and the second protrusion is an inverted structure, and the inverted structure is configured to seal the assembly gap between the soft rubber frame and the dust box and prevent the dust box filter from falling off from the dust box. Specifically, the inverted structure is an arc-shaped structure, and the arc-shaped structure is inclined toward the side opposite to the assembly direction of the dust box filter. Due to the inverted structure, during the assembly process of the dust box filter, the dust box filter is conveniently extended into the dust box assembly opening with friction, inclined toward the opposite side to the assembly direction, and then pressed and sealed between the dust box filter and the dust box.

[0077] In some embodiments, the second side wall of the soft rubber frame further includes at least one third protrusion 5012, the third protrusion 5012 being distributed on the outer circumferential surface of at least one soft rubber frame second side wall 50113 of the frame structure. The third protrusion 5012 may be a distributed multi-protrusion structure. In one embodiment, the third protrusions 5012 are distributed on the outer peripheral surface of the two second side walls 50113 of the frame structure. When the dust box filter is assembled into the dust box, the third protrusion 5012 on the outer peripheral surface of one soft rubber frame 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. At the same time, when assembling the dust box filter, the slightly long third protrusion 5012 is first inserted into the recess of the dust box side wall, and then rotated around the third protrusion 5012, and 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 the second side wall 50113 of another soft rubber frame of the frame structure have a smoother structure, and when the dust box filter is assembled into the dust box, the third protrusions 5012 on that side are interferingly engaged with the dust box side wall elastic structure 5013 to prevent the dust box filter from falling off, whereby the elastic structure 5013 is approximately an S-structure and includes an inner recess for accommodating the third protrusion 5012 and an outer protrusion engaged with the third protrusion 5012, and the outer protrusion can move elastically under the action of external force to be engaged with the third protrusion 5012, and Figure 15 is an installation structure diagram 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 soft rubber frame 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.In the process of mounting the dust box filter in the dust box, after the dust box filter is assembled in position, the first rib position 510 abuts against the pillow position 5014 provided at the corresponding position of the dust box side frame, preventing the filter from further stretching inward and preventing the dust box filter from being mounted too deeply in the dust box. At the same time, in the assembly process, if the first rib position 510 does not abut 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 position, and therefore the dust box filter can be prevented from being mounted too shallowly in the dust box.

[0078] In some embodiments, as shown in Figures 13a and 13b, the soft rubber frame further includes a sagging prevention protrusion 509, which is provided on the outer circumferential surface of the second side wall of the soft rubber frame and configured to prevent the dust box filter from being installed in the wrong direction. A recess is provided in the dust box at a position corresponding to the sagging prevention protrusion 509, and when the dust box filter is normally installed, the sagging prevention protrusion 509 enters the recess and the dust box filter is normally assembled, and when the dust box filter is installed in the wrong direction, the dust box filter cannot be assembled due to the sagging prevention protrusion 509 because there is no recess on the other side of the dust box, and it plays a role of preventing sagging, indicating that the installation direction of the dust box filter is reversed.

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

[0080] As shown in Figures 11 and 12, the soft rubber frame further includes a sealing inner lip 507, which is provided on the first end surface 50116 of the soft rubber frame 501 around the filter material 502 and 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 an approximately planar structure, and abuts against the first end surface 50116 of the soft rubber frame 501 and is assembled to the soft rubber frame; and a sealing outer lip 506 is provided on the second end surface 50115 of the soft rubber frame 501 around the filter material 502 and configured to seal the dust box filter and the edge of the air outlet 208 of the receiving cavity 200. The sealing inner lip 507 and the sealing outer lip 506 are higher than the first end surface 50116 or the second end surface 50115, 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, and because the sealing inner lip 507 is made of a soft material, it seals the dust box filter and the assembly surface of the dust box under the action of the pressing force, and when the dust box is assembled into the automatic cleaning device, the sealing outer lip of the dust box filter can be easily pressed against the assembly surface of the dust box. The side lip 506 is pressed between the dust box filter and the grill outer side of the air outlet 208 of the accommodating cavity 200, sealing the dust box filter and 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 arranged below the second cavity 202, and the grill-type air outlet 208 is arranged 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 surface of the dust box filter 500 and the dust box air outlet assembly surface, and between the outer end surface of the dust box filter 500 and the outer surface of the air outlet grille of the receiving cavity 200. This eliminates the traditional cumbersome step of adding sealing strips on the inside and outside of the dust box filter to meet the air passage sealing requirements. The soft rubber frame 501 is used as the carrier, and the sealing inner lip 507 and the sealing outer lip 506, which also have a certain degree of flexibility, are used as the sealing structure, making the contact, sealing and engagement tighter, more sufficient fit, and stronger sealing effect, which can ensure the airtight performance of the entire air passage, and plays a role in better guaranteeing the functions of the cleaning device such as dust suction and dust discharge by negative pressure.

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

[0082] In some embodiments, as shown in FIG. 11, the soft rubber frame further includes a magnetic device mounting hole 504, which is provided on the second end surface 50115 of the soft rubber frame 501 and is configured to be attached to a magnetic device to ensure that the dust box filter is mounted in a predetermined position, the magnetic device may be a magnet or other electromagnetic element, an inductive magnetic device is mounted in the magnetic device mounting hole 504, the magnetic device mounting hole 504 has a sufficient depth for the magnetic device to 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.

[0083] 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 encapsulates 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 location 5041 may be a soft rubber material and further encapsulates the magnetic device when pressed.

[0084] In some embodiments, as shown in Fig. 11, the soft rubber frame further includes a grommet 505, which is provided at a position extending outward from the step surface 503 and is configured to facilitate removal of the dust box filter. The shape and structure of the grommet 505 is not limited and may be semicircular, square, rectangular, etc.

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

[0086] In the automatic cleaning device described in the above embodiments, the dust box filter is designed with a soft rubber frame, so that during the assembly process, it is directly pressed and assembled into the dust box opening, and at the same time cooperates with the first protrusion, the sealing inner lip, the sealing outer lip and other structures, thereby achieving the effect of tightly sealing the filter and the assembly surface during assembly, thereby avoiding the traditional process of manually gluing the assembly parts with dot glue after being attached to the filter, simplifying the process and reducing the number of assembly parts, while reducing costs, without adhesive bonding, without odor, and more environmentally friendly.

[0087] In some embodiments, the present embodiment further provides a dust box, which includes the dust box filter described in the above some embodiments, as shown in Fig. 14. The structure of the dust box can be referred to in the above some embodiments, and the description is omitted here.

[0088] In some embodiments, an automatic cleaning device is further provided, which includes a dust box as described in the above embodiments, and the structure of the automatic cleaning device can be referred to in the above embodiments, and the description will be omitted here.

[0089] After the automatic cleaning device finishes suctioning, it enters the dust collection station to automatically collect dust. When the automatic cleaning device automatically collects dust, there is only one air passage entering the automatic cleaning device, and the air passage is blocked by the equipment structure and not smooth, so it is difficult for the dust collection station to suck all the garbage in the dust box into the garbage bag of the dust collection station. In order to dispose of the garbage in the dust box as cleanly as possible, the power of the fan of the dust collection station needs to be increased, resulting in louder noise and more energy consumption.

[0090] In this regard, the embodiment of the present disclosure further provides an automatic cleaning device with a dust collection function, and improves the airway structure of the automatic cleaning device so that the airflow can more easily enter the dust box during the dust collection process, and the garbage in the dust box can be more easily cleaned. This embodiment describes some structural features compared with the above embodiment, and the same structure has similar technical effects, and some technical effects are not described here. Specifically, according to a specific embodiment of the present disclosure, the present disclosure provides an automatic cleaning device with dust collection function, which includes a moving platform 100, the moving platform 100 is configured to move automatically on an operating surface, the moving platform 100 mainly includes an upper casing, a lower casing, a side casing which form the outer shape of the automatic cleaning device, and structures and accessories provided in the internal space of the casing, specifically, the moving platform 100 includes an accommodating cavity 200 and a driving wheel assembly 141, the accommodating cavity 200 is provided approximately at the rear half position in the forward direction of the moving platform, the accommodating cavity 200 is formed recessed inward, and the driving wheel assembly 141 is provided on the lower casing of the moving platform 100 as mentioned above, and is used to provide forward power for the automatic cleaning device. The moving platform 100 further includes a cleaning module 150, which includes a dust box 300 and a main brush module 153, and the dust box 300 is detachably assembled to the storage cavity 200, and some of the structure of the dust box 300 can be referred to the above embodiment and will not be repeated here.The dust box 300 further includes a first air inlet 3013 and a second air inlet 3014, the first air inlet 3013 and the second air inlet 3014 being respectively located on a first side wall 3015 and a second side wall 3016 of the dust box, the first air inlet 3013 and the second air inlet 3014 being configured to provide intake airflows in two different directions during a dust collection process, which contributes to forming an airflow vortex in the dust box during dust collection, and improves the airflow of the dust box. The dust collector greatly reduces the dust residue in the dust box, reduces the airflow dead space, and improves the dust collection efficiency; the installation of two air inlets increases the suction speed and improves the formation efficiency of the airflow vortex, where the source of the suction airflow includes at least one of the airflow I entering through the gap at the top end of the moving platform 100, the airflow II entering through the gap of the main brush module 153, the airflow III entering through the rear side wall of the moving platform, and the airflow IV entering through the gap of the driving wheel assembly 141. By setting up multiple sets of suction airflows, the suction volume and suction speed of the automatic cleaning device are increased, the dust collection strength and dust collection efficiency of the dust collection station are improved, and the airflow dead space in the dust box is further reduced, the dust residue is reduced, and the dust collection rate is improved.

[0091] After the automatic cleaning device has completed its dust suction, when it returns to the dust collection station to perform dust collection operation, the fan of the dust collection station starts to suck up the dust in the dust box. During the suction process, the airflow passes through multiple flow paths and enters the dust box from the first air inlet 3013 and the second air inlet 3014, and then is sucked in from the dust collection port by the dust collection station together with the dust. In the dust collection state, the main cleaning brush of the automatic cleaning device moves in the reverse direction with the start of the fan of the dust collection station, the automatic cleaning device enters the "dust discharging" state, the airflow enters the internal cavity of the dust box from the outside of the automatic cleaning device through the gaps in the casing of the automatic cleaning device, the airflow forms a vortex in the internal cavity of the dust box, the dust in the internal cavity of the dust box rotates and is lifted up, the dust collection fan of the dust collection station is started, the main brush, the first opening 3011 of the dust box and the internal cavity of the dust box are connected through a specific air passage, and then the suction force sucks the dust in the internal cavity of the dust box into a dust storage container or bag inside the dust collection station.

[0092] Here, the airflow entering the dust box mainly includes the airflow I entering through the gap at the top end of the moving platform 100, and as shown in FIG. 16, specifically, the airflow I entering through the gap at the top end of the moving platform 100 includes the airflow entering through the gap between the cover 940 and the top surface of the moving platform 100, and the airflow entering through the gap between the cover 940 and the positioning element 1211. In the present disclosure, when the cover 940 and the positioning element 1211 are assembled, an airflow gap is formed between the cover 940 and the top surface of the moving platform 100, and between the cover 940 and the positioning element 1211, by a supporting structure such as a protrusion, and a negative pressure is formed in the dust box 300 that is in fluid communication with the fan of the dust collection station due to the suction of the fan of the dust collection station, and the first air inlet 3013 and the second air inlet 3014 are opened toward the inside of the dust box to guide the airflow outside the dust box to enter, and a negative pressure is also formed in the moving platform, and the gas outside the moving platform is guided between the cover 940 and the The airflow is guided to enter the inside of the device through the airflow gaps formed between the cover 940 and the top surface of the moving platform 100 and between the cover 940 and the positioning element 1211, and compared with the conventional sealing structure, the airflow gaps formed between the cover 940 and the top surface of the moving platform 100 and between the cover 940 and the positioning element 1211 increase the number of airflow paths, ensure sufficient airflow enters the dust box, further increase the intake air volume and intake air speed of the dust box, improve the dust collection strength and dust collection efficiency of the dust collection station, reduce the airflow dead space in the dust box, reduce dust residue, and improve the dust collection rate. More importantly, the airflow is guided to pass around the positioning element 1211, which helps to remove excess heat generated by the positioning device during operation, plays a cooling role, improves the working stability of the positioning device, and helps to extend the life of the electronic device. In addition, the airflow at the top is cleaner than other parts, and is safer and more friendly to the airway inside the device.

[0093] The airflow entering the dust box further includes airflow II entering through the gap of the main brush module 153. As shown in FIG. 17, airflow II enters the casing through the assembly gap of the main brush module 153 on the bottom surface of the lower casing of the moving platform 100, whereby the edge gap of the main brush module 153 and the edge gap of the driving wheel assembly 141 are formed by the protrusion or groove or self-contained assembly gap during the assembly of the device, and the negative pressure is formed inside the moving platform by the suction of the fan of the dust collecting station, and the gas outside the moving platform is sucked through the edge gap of the main brush module 153. Compared with the conventional sealing structure, more air flow paths can be formed in the edge gaps of the main brush module 153, which can further ensure that sufficient airflow enters the dust box and further improve the suction volume and speed of the dust box. This improves the dust collection strength and dust collection efficiency of the dust collection station, while reducing the airflow dead space in the dust box, reducing garbage residue and improving the dust collection rate. Furthermore, the distance until the airflow II reaches the two air inlets of the dust box is short and the duct is smooth, which further improves the airflow replenishment speed and ensures dust collection efficiency.

[0094] In some embodiments, an exhaust port 204 is provided on the rear wall of the moving platform 100, where the sets of intake airflows further include an airflow III entering from the exhaust port 204 in a dust collection state, as shown in FIG. 3a; as shown in FIG. 18a, the exhaust port 204 is in a dust collection state, and a negative pressure is formed inside the moving platform through the suction of the fan of the dust collection station, which guides the gas outside the moving platform to enter the inside of the equipment through the exhaust port 204; specifically, as shown in FIG. 18b, the gas is guided through the exhaust port 204. 04 into both sides of the fan bracket, then through the air inlet notches 20115 of the sealing baffles 20114 on both sides of the fan bracket, into the outer side wall of the receiving cavity, and then through the air intake holes 20111 on the outer side wall of the receiving cavity, so as to further ensure that sufficient airflow enters the dust box, further improve the intake volume and intake speed of the dust box, improve the dust collection strength and dust collection efficiency of the dust collection station, further reduce the airflow dead space in the dust box, reduce the dust residue, and improve the dust collection rate. During the dust collection process, the rear side of the moving platform 100 is fully exposed to the environment, and the exhaust port provided therein functions as an airflow inlet, which can more smoothly replenish the airflow, reduce the interference of the airflow caused by external equipment or the environment that contacts or fits with the cleaning device, and more safely and efficiently replenish the airflow. In some embodiments, the air inlet notches 20115 are provided at the bottom of the sealing baffles 20114 to reduce the impact of the airflow on other components.

[0095] 18a, the airflow entering the dust box further includes airflow IV entering through the gaps in the drive wheel assembly 141, and the drive wheel is provided with an intake passage, and the airflow entering the casing through the gaps in the edge of the bottom of the drive wheel directly enters both sides of the accommodation cavity through the intake passages on the upper rear side of the drive wheel, and then directly enters the dust box through the intake hole 20111. The path of the airflow IV entering through the gaps in the drive wheel assembly 141 is shorter, making it easier to enter the airflow passage of the dust box, and providing more incoming airflow.

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

[0097] As shown in FIG. 18b, the rear side of the moving platform includes a fan bracket 20116 and a baffle 20114 on both sides of the fan bracket 20116, the baffle 20114 is connected to the upper and lower surfaces and side walls of the casing, the baffle 20114 seals the fan bracket 20116 at the rear end of the moving platform, and the fan is connected to some exhaust ports 204 on the rear side wall of the moving platform through the air exhaust pipe, these exhaust ports are called first exhaust ports, when the automatic cleaning device is cleaning, the fan exhausts air through the air exhaust pipe to some exhaust ports 204 that communicate with the air exhaust pipe, i.e., the first exhaust port, and when collecting dust, the fan The air is drawn in through other exhaust ports 204 around the above-mentioned part of the exhaust ports 204, i.e., the second exhaust ports, which are mostly intake ports that do not directly communicate with the fan air exhaust pipe, and an air inlet notch 20115 is provided on the baffle 20114, so that the III-path airflow enters the inside of the moving platform casing through the second exhaust port 204, and then reaches the plurality of air intake holes 20111 on the side of the accommodating cavity 200 through the air inlet notches 20115 of the baffles 20114 on both sides of the fan bracket, and enters the accommodating cavity 200 through the plurality of air intake holes 20111, and then enters the dust box through the first air inlet 3013 and the second air inlet 3014.

[0098] As an optional embodiment, the exhaust port 204 further includes a third exhaust port on the side opposite to the first or second exhaust port of the baffle 20114, i.e., those exhaust ports 204 shown in FIG. 18b, whereby the III path airflow enters from the third exhaust port, and the III path airflow reaches the plurality of air intake holes 20111 on the side of the accommodating cavity 200 directly from the third exhaust port, enters the accommodating cavity 200 from the plurality of air intake holes 20111, and enters the dust box via the first air inlet 3013 and the second air inlet 3014, thereby improving air replenishment efficiency.

[0099] In some other embodiments, the third exhaust port may be a decorative hole that is not open or does not penetrate, but only serves a decorative function, thereby avoiding unnecessary communication between the inside and outside of the automatic cleaning device and controlling the air inlet of the automatic cleaning device.

[0100] In some embodiments, as shown in Fig. 20, the storage cavity 200 further includes a third side wall 2011 corresponding to the first side wall 3015 of the dust box and a fourth side wall 2012 corresponding to the second side wall 3016 of the dust box, the third side wall 2011 and the fourth side wall 2012 each have a plurality of air intake holes 20111, and the plurality of air intake holes 20111 cover at least a part of the first air inlet 3013 and the second air inlet 3014. The outsides of the third side wall 2011 and the fourth side wall 2012 of the storage cavity 200 respectively include a plurality of spacers 20112, and the plurality of spacers 20112 form a plurality of air passages. In some embodiments, the top end of each of the spacers 20112 includes at least one notch 20113 communicating with the plurality of air passages. The multiple air passages formed by the multiple spacers 20112 can ensure the uniformity of the airflow entering the accommodating cavity 200, and prevent a part of the airflow from reaching the outside of the air intake holes 20111, i.e., the airflow that enters the accommodating cavity 200 but cannot immediately reach the dust box, resulting in airflow loss, and at the same time, the lost airflow forms convection with the I-IV path airflow, affecting the efficiency of airflow entering the dust box. After providing the multiple spacers 20112 to form a communication structure, the multiple air passages can reach the accommodating cavity 200 more uniformly through the multiple air intake holes 20111, and enter the dust box more efficiently.

[0101] In some embodiments, as shown in Fig. 21, the first air inlet 3013 and the second air inlet 3014 are respectively arranged at asymmetric positions on the first side wall 3015 of the dust box and the second side wall 3016 of the dust box, to avoid the airflows entering from two sides being directly offset, and the intake airflows entering from two different directions intersect, which helps to more quickly form an airflow vortex in the dust box during dust collection, increase the swirling speed of the airflow entering the dust box, greatly reduce the amount of dust remaining in the dust box, reduce the dead space of the airflow, and improve the dust collection rate. In some embodiments, the second air inlet 3014 is arranged at a position close to the lower edge of the second side wall 3016, and the lower edge of the second air inlet 3014 is lower than the lower edge of the first air inlet 3013, thereby further increasing the swirling speed of the airflow entering the dust box. In some embodiments, the second air inlet 3014 is provided adjacent to the rear wall of the dust box, and the first air inlet 3013 is provided adjacent to the front wall of the dust box, so as to further increase the swirling speed of the airflow entering the dust box, where in an assembled state, the front wall of the dust box is the side wall facing the forward direction of the automatic cleaning device of the dust box, and the rear wall of the dust box is the side wall facing the tail of the automatic cleaning device with respect to the front wall. In some embodiments, the first air inlet 3013 rotates approximately around a first rotation axis, and the second air inlet 3014 rotates approximately around a second rotation axis, where the first rotation axis is approximately perpendicular to the second rotation axis, so as to further increase the swirling speed of the airflow entering the dust box, where the first rotation axis and the second rotation axis may be actual rotation axes provided at the first air inlet 3013 and the second air inlet 3014, or may rotate around the position of the first rotation axis and the second rotation axis via an elastic drive member.

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

[0103] In some embodiments, the shapes of the first air inlet 3013 and the second air inlet 3014 include at least one of a rectangle, a square, a circle, an ellipse, and an elongated shape, or a combination thereof, including but not limited to these. In some embodiments, the first air inlet 3013 has a rectangular structure, and the long side of the first air inlet 3013 is arranged along a vertical direction, and the second air inlet 3014 has a rectangular structure, and the long side of the second air inlet 3014 is arranged along a horizontal direction, and by arranging the first air inlet 3013 and the second air inlet 3014 according to the above structure, the airflow forms a vertical vortex and a horizontal vortex, which lifts up dust from multiple angles in all directions, efficiently improving the dust collection rate, and further increasing the swirling speed of the airflow entering the dust box. Furthermore, the first air inlet 3013 and the second air inlet 3014 have a structure that opens inward. As shown in FIG. 21, when the first air inlet 3013 opens inward, the damper is half-open, and the damper opening faces the front wall of the dust box, so that when air flows in, it is blown directly toward the front wall of the dust box; when the second air inlet 3014 opens inward, the damper is also half-open, and the damper opening faces the bottom of the dust box, so that when air flows in, it is blown directly toward the bottom of the dust box; the air flows coming in from the two dampers do not blow against each other, but form a swirling airflow, which accelerates the rotation of the dust in the dust box and promotes the circulation of the dust to the dust outlet so that it can be sent out of the dust box.

[0104] In some embodiments, the dust box 300 further includes a first opening 3011 and a second opening 3012, the first opening 3011 is configured to function as a dust inlet during dust suction and a dust outlet during dust collection, the dust inlet during dust suction and the dust outlet during dust collection are provided as the same opening, the number of ports can be reduced, the existing ports can be efficiently shared, and the probability of air leakage can be reduced, and a filter is provided on the second opening 3012, the specific structure and installation method can be referred to the above embodiments, and the description will be omitted here, as shown in FIG. 22, the first opening 3011 and the second opening 3012 are located approximately on the central axis line in the front-rear direction of the automatic cleaning device, and with this design structure, when dust is suctioned through the fan of the automatic cleaning device, the air passage has a linear structure, which can avoid the airflow from detouring and improve the smoothness of the air passage.

[0105] In some embodiments, the receiving cavity 200 includes a first cavity 201 and a second cavity 202, which are adjacently arranged in front and rear in the forward direction of the automatic cleaning device, a dust suction port 203 is provided at the bottom of the front wall of the first cavity 201, an air outlet 208 is provided at the rear wall of the connection between the first cavity 201 and the second cavity 202, and the dust suction port 203, the air outlet 208, the first opening 3011, and the second opening 3012 are all located approximately on the central axis of the front and rear direction of the automatic cleaning device. During dust suction or collection, the airflow is zigzag and does not pass through a duct or airway, so that fan power and suction loss are reduced, the effectiveness of the fan is maximized, energy is saved, and noise is reduced.

[0106] In some embodiments, the moving platform 100 includes a positioning element 1211 that is approximately on the central axis of the moving platform 100 in the forward and backward direction, and a cover 940 that is arranged to cover the upper side of the positioning element 1211. A fan is arranged in the lower space of the second cavity 202, and the positioning element 1211, the cover 940, the fan, the main brush module 153, the dust suction port 203, the air outlet 208, the first opening 3011, and the second opening 3012 are all approximately on the central axis of the automatic cleaning device in the forward and backward direction. In the related art, when there is only one air inlet, the intake airflow is not symmetrical, the dust inlet is usually offset, which is unsightly, and the inlet and outlet passages of the entire airway are not straight, which causes airflow blockage and loss, and at the same time affects the layout of other devices. After adding the air inlet, the above airway structure is arranged on the central axis, which can avoid the disadvantages of the existing dust collection method such as low dust collection rate and residual dust collection. This overcomes the technical shortcomings of the existing technology, such as the offset air passage, which causes losses in fan power and suction force due to passing through a zigzag duct, while at the same time greatly improving the appearance of the design and the space required for arranging components. The port of the main brush module 153 is also located on the central axis, which ensures that the dust suction air passage is not obstructed, reducing losses and improving efficiency.

[0107] According to a specific embodiment of the present disclosure, the present disclosure provides an automatic cleaning system including a dust collection station and an automatic cleaning device described in any one of the above claims, wherein the dust collection station includes a dust collection port, and the dust collection port is connected to a port of the main brush module to collect dust.

[0108] FIG. 23 is a schematic structural diagram of a dust collection station provided according to some embodiments of the present disclosure, where the dust collection station 700 is configured to provide dirt collection for an automatic cleaning device.

[0109] As shown in FIG. 23, the dust collection station 700 includes a dust collection station base 710 and a dust collection station body 720. The dust collection station body 720 is configured to collect the dirt in the dust box of the automatic cleaning device and is provided on the dust collection station base 710. The dust collection station base 710 includes a dust collection port 711, which is connected to a port of the main brush module of the automatic cleaning device, and the dirt in the dust box of the automatic cleaning device enters the dust collection station body 720 through the dust collection port 711. In some embodiments, as shown in FIG. 22, a seal gasket 714 is further provided around the dust collection port 711, which is used to butt and seal the dust collection port 711 with the port of the main brush module of the automatic cleaning device to prevent dirt leakage.

[0110] FIG. 24 is a schematic diagram of the scene after the automatic cleaning device provided by some embodiments of the present disclosure returns to the dust collection station. As shown in FIG. 24, after the moving platform 100 of the automatic cleaning device, e.g., a cleaning robot, returns to the dust collection station 700 after completing cleaning, the automatic cleaning device moves along the X direction to the dust collection station base 710, aligns the port of the main brush module of the automatic cleaning device with the dust collection port 711, and transfers the garbage in the dust box of the automatic cleaning device into the garbage bag of the dust collection station.

[0111] The present disclosure provides an automatic cleaning device and system, the automatic cleaning device having an automatic dust collection function, and by asymmetrically providing two dampers in the dust box of the automatic cleaning device, the airflow entering the dust box forms a convection current, which forms a vortex wind within the dust box, and smoothly sucks up the dust in the dust box into a dust collection station; and by providing a main brush module, a dust suction port, an air outlet, a first opening, and a second opening substantially on the central axis line in the front-to-rear direction of the automatic cleaning device, the speed of the airflow flowing through the dust box during dust suction is further increased, improving the dust suction efficiency, and at the same time, the dust in the dust box can be easily sucked into the dust collection station during dust collection.

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

[0113] For this reason, the embodiment of the present disclosure provides an automatic cleaning device that assembles a miniaturized positioning element in the original assembly space, and the positioning device described in this embodiment includes, but is not limited to, a camera and a laser distance measuring device (LDS). For ease of understanding, the positioning device described in this embodiment is described as a laser distance measuring device, but this embodiment makes the application of the positioning device more flexible by rationally setting the structure and positional relationship of the assembly bracket, rotor, motor, cover, etc., and the same structure has the same technical effect, and the partial technical effect is not described here. Specifically, as shown in Fig. 25, the automatic cleaning device includes an assembly part 800 provided on a rack, an assembly structure 900, and a positioning element 1211, the positioning element 1211 is assembled to the assembly part 800 through the assembly structure 900, the assembly part 800 is usually a part of a rack and has one or more screw holes, the assembly structure 900 has one or more corresponding screw holes, and the positioning element 1211 is assembled to the assembly part 800 through a bolt, and the assembly part 800 and the positioning element 1211 are assembled in the automatic cleaning device at the site where they are assembled. Usually, after the design of each part of the automatic cleaning device is completed, the position and size are constant, and correspondingly, the spatial position of the spare assembly part 800 is also constant, so that when a smaller-sized positioning element of the automatic cleaning device needs to be replaced, it cannot fit the spare assembly part 800, so that the assembly structure of the automatic cleaning device and the structure of the positioning element of the embodiment of the present disclosure are improved as follows:

[0114] As shown in FIG. 26, the assembly structure 900 includes an assembly bracket 910, and the positioning device includes a rotor 920, a motor 930, a cover 940, etc., the assembly bracket 910 is fixed to the assembly part 800 through screw holes around the bracket, the rotor 920 and the motor 930 are installed inside the assembly bracket 910, and the cover 940 is installed to cover the top of the rotor 920 and performs a shielding and protection function, the rotor 920 protrudes from the top surface of the automatic cleaning device, and the rotor 920 continuously rotates and scans within a 360-degree range, thereby detecting obstacles without interruption during the operation of the automatic cleaning device. As shown in FIG. 27, the assembly bracket 910 includes a rotor accommodating portion 911 and a motor accommodating portion 912, the rotor accommodating portion 911 includes a first arc-shaped sidewall 9111, the first arc-shaped sidewall 9111 includes an arc-shaped sidewall or an arc-shaped sidewall of other curvature, where the arc-shaped sidewall is at least a portion of a circle, and as shown in FIG. 27, the first arc-shaped sidewall 9111 is a majority of the circular structure, for example a portion within a range of 180 to 270 degrees, and the motor accommodating portion 912 includes a second arc-shaped sidewall 9121, the second arc-shaped sidewall 9121 is a portion of the circular structure. The rotor accommodating part may be a portion having an arc-shaped structure with a different arc degree, or a portion having a circular structure or an arc-shaped structure and a linear structure, but is not limited to these. The first arc-shaped side wall 9111 of the rotor accommodating part and the second arc-shaped side wall 9121 of the motor accommodating part are smoothly connected, and are divided into the rotor accommodating part 911 and the motor accommodating part 912 at approximately MN, as shown in FIG. 27, and here the opening area formed by the first arc-shaped side wall 9111 is larger than the opening area formed by the second arc-shaped side wall 9121. The positioning element 1211 includes a rotor 920, and the rotation axis of the rotor 920 is disposed approximately at the geometric center of the rotor accommodating portion 911. When the first arc-shaped side wall 9111 is an arc-shaped side wall, the geometric center of the rotor accommodating portion 911 corresponds to the center of the circle in which the first arc-shaped side wall 9111 is located. When the first arc-shaped side wall 9111 is a combination structure of arcs with multiple different curvatures, the geometric center of the rotor accommodating portion 911 corresponds to the center of the circle in which the arc with the maximum arc degree is located, for example, at A shown in FIG. 27.The rotor 920 is configured to transmit and / or receive detection signals, such as visible light and / or invisible light, while rotating continuously, and the rotor 920 has a smaller diameter, i.e., a greater distance to the first circular arc-shaped side wall 9111 of the rotor housing compared to the rotor of the conventional positioning element, but is still assembled at the geometric center of the rotor housing 911 to ensure the symmetry of the structure and stability after rotation. The positioning element 1211 includes a motor 930, and the output shaft of the motor 930 is approximately provided at the connecting part between the rotor housing 911 and the motor housing 912, i.e., approximately located on the connecting line between the geometric center of the motor housing and the geometric center of the rotor housing, for example, at B in FIG. 27, specifically, approximately located between the connecting line between the geometric center C of the motor housing and the geometric center A of the rotor housing, except for points A and C, i.e., closer to the geometric center A of the rotor housing than the geometric center C of the motor housing. This allows the motor of the miniaturized positioning element to be closer to the rotor, and the internal accommodation structure of the assembly bracket can be more compatible with the motor and rotor of the positioning element, which can increase stability, reduce the size of the transmission element, e.g., the belt, and reduce energy loss and material costs. In some embodiments, the communication portion is located approximately at the center of the smooth connection between the first arc-shaped side wall 9111 and the second arc-shaped side wall 9121, i.e., the MN connection line. If the second arc-shaped side wall 9121 is an arc-shaped side wall, the geometric center of the motor accommodation portion 912 corresponds to the center of the circle in which the second arc-shaped side wall 9121 is located, and if the second arc-shaped side wall 9121 is a combination structure of multiple arc-shaped shapes with different curvatures, the geometric center of the motor accommodation portion 912 corresponds to the center of the circle in which the arc with the maximum arc degree is located, as shown in FIG. 27C. The motor 930 is configured to be connected to the rotor via a transmission structure 932, e.g., a belt, to provide a driving force to the rotor. Here, the motor 930 drives the rotor 920 through the motor roller 931 and the transfer structure 932, the transfer structure 932 may be a belt, a metal belt, an organic material belt, etc., and the rotation shaft of the motor 930 is hardwired to the motor roller 931, and the motor roller 931 rotates freely under the drive of the motor rotation shaft.

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

[0116] In some embodiments, as shown in FIG. 27, the motor accommodating portion 912 includes an opening 19122 located on a bottom surface 9124 of the motor accommodating portion 912 and configured to accommodate the motor 930, and a first support rib 9123 extending inward along the inner side of the motor accommodating portion side wall 9121 to the edge of the opening 19122, wherein the geometric center B of the opening 19122 is closer to the geometric center A of the rotor accommodating portion than the geometric center C of the motor accommodating portion, wherein the geometric center B of the opening 19122 is located approximately at the center of the circle in which the arc of the opening 19122 is located, and the geometric center C of the motor accommodating portion is located approximately at the center of the circle in which the motor accommodating portion side wall 9121 is located. Compared with the conventional size motor, its mounting position is usually at the geometric center C of the motor housing, but if the entire structure of the positioning element is small and the rotor 920 is still at the geometric center A of the rotor housing, it can reduce the transmission loss, increase the transmission efficiency, and improve the stability during belt transmission, and the motor 930 is assembled close to the rotor, and at this time the rotation gap between the motor 930 and the rotor 920 is almost constant, and a considerable transmission efficiency can be maintained, which is suitable for a more miniaturized positioning element, without separate molding, reducing costs, and the motor is closer to the rotor, saving the transmission device such as the belt, further reducing costs, and at the same time reducing the transmission resistance and improving the transmission efficiency. At this time, in order to increase the stability and rigidity of the assembly bracket 910, it is necessary to add a first support rib 9123, and especially the greater the distance from the motor, the longer the first support rib 9123 is.

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

[0118] In some embodiments, as shown in Fig. 27, the opening 2 communicates with the opening 1, and the area of ​​the opening 2 is larger than that of the opening 1. The opening 2 communicates with the opening 1 to reduce the machining process of the bracket structure, and the communication structure drives the motor to rotate the rotor through the transfer structure.

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

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

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

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

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

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

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

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

[0127] In the related art, the top of the automatic cleaning device is not completely closed, so there is a risk of water entering the inside. For example, if a user accidentally spills water on the automatic cleaning device, the water may enter the automatic cleaning device through a gap on the top cover of the automatic cleaning device, such as a gap in a positioning device, and may damage elements such as a circuit board, leading to a failure of the automatic cleaning device.

The water-blocking rib 1022 can effectively guide the condensed water formed on the inner surface of the top casing after the water vapor that may be generated in the automatic cleaning device rises and condenses, and prevent the condensed water from moving toward the surface of the mobile platform body along the platform cover 102, flowing above the circuit board 105 beyond the water-blocking bracket 104 from above and dripping down, thereby preventing the electronic elements on the circuit board 105 from being damaged.

In this way, there is no need to provide a top flap, which simplifies the device structure and further improves the technical and aesthetic appearance of the automatic cleaning device.

[0137] The platform base plate 103 is provided at the bottom of the moving platform body 101 and faces the platform cover 102.

The circuit board 105 is a circuit element in the automatic cleaning device and is generally located on the side of the positioning device closer to the front part of the automatic cleaning device.

[0140] In the present disclosure, since external liquid, such as water, may flow into the inside of the automatic cleaning device through a gap between the positioning device and the platform cover 102, the waterproof bracket 104 can prevent liquid from flowing into the circuit board from the position of the positioning device, so that the waterproof bracket can be provided between the receiving cavity and the circuit board to enable waterproofing.

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

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

[0153] The automatic cleaning device provided by the present disclosure has a water-tight bracket between the circuit board and the accommodating cavity, which can prevent liquid flowing in from the outside from entering the circuit board and damaging the circuit elements, and omits the top flap design in the original automatic cleaning device, simplifying the structure of the device, and improving the technical and aesthetic appearance of the automatic cleaning device.

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

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

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

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

[0158] The trigger assembly 182 further includes a warp prevention fastener 1823 and a positioning post 1824, and the warp prevention fastener 1823 prevents the elastic plate member from being biased and warped in a direction away from the bottom of the accommodating groove 1012. The warp prevention fastener 1823 is located on a side wall of the accommodating groove 1012 away from the elastic plate member fixed end 18221, and when the elastic plate member 1822 is in an unbiased state, the free end of the warp prevention fastener 1823 is as close as possible to the surface of the elastic plate member away from the bottom of the accommodating groove 1012.

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

[0160] During the process of performing a cleaning operation, when the automatic cleaning device is caught by an obstacle above, the positioning device 121 pivots around the pivot shaft 1043, the base plate moves in a direction closer to the trigger assembly 182, and the trigger button 1821 is triggered by the trigger protrusion 181 on the base plate. When the trigger button 1821 is triggered, an anti-trap control signal is generated and sent to the control system 130, and then the control system 130 generates a corresponding control command to make the cleaning device perform an anti-trap operation, including but not limited to stopping, reversing, steering, etc. The trigger button 1821 has a certain pressing stroke, and the motion amplitude generated by the base plate 1221 due to an upper obstacle is usually equal to or less than the pressing stroke of the trigger button 1821, so that the anti-trapping control signal can be safely generated. If the running speed of the cleaning device is too fast and the height of the upper obstacle is too low, the pivoting amplitude of the positioning device 121 may be too large, so that the movement amplitude of the trigger protrusion 181 caused by the base plate 1221 exceeds the pressing stroke of the trigger button 1821, leading to damage to the trigger button. On the other hand, if the trigger button 1821 is provided on the free end 18222 of the elastic plate member 1822, the pressing force due to the excessive movement acts on the free end, and the trigger button 1821 continues to move downward together with the free end 18222, and this buffering action can avoid damage to the trigger button 1821, extend the service life of the anti-trapping element, and improve the safety of the cleaning device. At the same time, after the automatic cleaning device leaves the obstacle above, the elastic plate member 1822 generates a reaction force to move away from the bottom of the receiving groove and warps, and the elastic plate member is finally parallel to the plane where the bottom of the receiving groove is located under the blocking action of the warp prevention fastener 1823, and is ready to trigger the next possible anti-hooking control signal. The installation of the elastic plate member 1822 ensures the working safety of the trigger button 1821, and at the same time avoids the use of other additional elements such as springs, making the structure of the device more simplified, facilitating maintenance and replacement of elements, and reducing the interference of surrounding metal parts with the positioning element.

[0161] The pressing structure on the cover of the existing automatic cleaning device is complicated. For example, most of the button structures of the existing cleaning devices are provided with a soft rubber bracket on a hard rubber bracket, and after bonding the hard rubber cap and the soft rubber bracket, the soft rubber bracket and the top casing decorative cover of the device are bonded with double-sided adhesive tape, and the hard bracket is fixed to the top casing through a hook on the lower side. Such a button assembly structure is complicated, has a large number of parts, requires a long assembly time, is complicated, and is expensive. Due to such a multi-layer structure, when attaching the soft rubber bracket to the top casing decorative cover of the device, the soft rubber is easily misaligned, making it difficult to attach and detach the button, and when attaching and detaching, the double-sided adhesive tape and the soft rubber are firmly bonded, so that the double-sided adhesive tape and the soft rubber are easily destroyed, and the button cannot be reused.

[0162] As a result, the embodiments of the present disclosure provide an automatic cleaning device without a flip cover, simplifying unnecessary elements of the button assembly of the automatic cleaning device while increasing the space from below the button assembly to above the circuit board, so that more electronic components can be placed in the space, and at the same time increasing the elastic force of the button assembly, making it easier to perform pressing. Specifically, the present disclosure provides an automatic cleaning device, and as shown in FIG. 43, according to a specific embodiment of the present disclosure, the present disclosure provides an automatic cleaning device, which includes a moving platform 100 that automatically moves on an operation surface, includes a cover 1000, and constitutes at least a part of the top surface of the moving platform; and a button assembly 400 that is used to be manually operated and pressed to control the operation of the automatic cleaning device, includes a cap 410 and a bracket 420, and is assembled to the cover 1000, where the cover 1000 has a button mounting hole 1002, the button assembly 400 includes a pressing body part 411, the pressing body part 411 is assembled to the button mounting hole 1002, and the top surface of the pressing body part is approximately flush with the top surface of the cover, and the user only needs to apply an acting force to the pressing body directly when operating, and no additional decorative parts are required, and in some embodiments, the top surface of the pressing body part is slightly lower or slightly higher than the top surface of the cover. Therefore, the user can easily identify the position of the button assembly by touch alone. Here, the button assembly 400 can be applied to the housing of any device that requires a mechanical button, including, but not limited to, a cleaning robot, a mopping robot, a sweeping and mopping robot, a handy robot, a watering robot, etc., and the button assembly may be typically provided on the top surface of the housing of the mechanical device or on the side of the housing of the mechanical device, and is not limited thereto. The housing of the mechanical device is typically formed of a hard plastic, resin, metal, or alloy material, and is not limited thereto.

[0163] Specifically, as shown in Fig. 43 to Fig. 47, the button assembly 400 includes a cap 410 and a bracket 420, the cap 410 is usually made of a soft rubber opaque material, which provides sealing, waterproofing and light-shielding during interference assembly, and the bracket 420 is usually made of a hard rubber material, which provides a supporting function during the cap assembly process and is fitted into a hard cover to fix the cap. As shown in Fig. 43, in the assembly process, the soft rubber cap is assembled to the cover from bottom to top, at least the pressing body part 411 is assembled to the corresponding button mounting hole 1002, and then the hard rubber bracket is assembled below the soft rubber cap, and the fixing is realized by the positioning post body 1001 on the cover 1000 and the positioning hole 425 on the bracket 420, forming a button assembly, and the two circular positioning holes 425 on the button bracket and the positioning post body 1001 with the fastening structure on the cover simultaneously perform a positioning function, and the cap 410 is assembled between the bracket 420 and the cover.

[0164] In some embodiments, as shown in FIG. 45, the bracket 420 has a stepped structure 430 extending along the circumferential direction, and in an assembled state, the stepped structure is a step that rises continuously from the outside to the inside or from the inside to the outside. Compared with an overall flat bracket, the rising portion in the stepped structure provides other components with arrangement space and design freedom, and the space above the bracket can be effectively utilized. Specifically, the direction of the step can be designed according to the space requirements of other components. Optionally, in an assembled state, the stepped structure is a step that rises continuously from the outside to the inside, and the step that rises continuously from the outside to the inside increases additional space, and the increased additional space is in the middle, and sufficient space required for the pressing operation is secured below the corresponding pressing body, which contributes to rationally setting the pressing stroke and elastic recovery, and can improve the user's comfort. The steps of each layer of the stepped structure 430 extend circumferentially with respect to the overall outer peripheral contour shape of the bracket 420 to form a closed structure, for example, but not limited to, a closed ellipse, circle, square, rectangle, etc. The step structure 430 has a step that rises continuously from the outside to the inside, forming a substantially tapered step structure, extending upward from the outer step to the inner step, and the specific number of steps is not limited, for example, 2 to 5 steps, for example, 2 to 3 steps, and the width and height of each step are not limited, and may be the same width and height, or may be steps of different widths and different heights, as shown in Figures 44 and 45. The bracket 420 has a larger protruding space below the bracket due to the step structure 430 extending along the circumferential direction, and the lower part of the bracket is the connected circuit board 105, so that the protruding space at this time gives the circuit board more convenience in component design than a closed space, and more electronic components can be placed by utilizing the space occupied by the lower part of the conventional bracket.In addition, the bracket 420 has a stepped structure 430 extending along the circumferential direction, which provides a larger protruding space below the bracket, thereby increasing the elasticity of the hard bracket. After the pressing force applied to the button assembly is transmitted to the hard bracket, the bracket is more likely to elastically deform and to recover easily after elastic deformation, giving the button assembly a better tactile feel and increasing the convenience of pressing contact with the device.

[0165] In some embodiments, as shown in FIG. 44, the bracket 420 includes a bracket first side wall 421 that extends continuously along the circumferential direction of the outer edge of the bracket 420, and a bracket second side wall 422 that extends continuously along the inner circumferential direction of the bracket 420, where a first assembly part 423 is formed between the bracket first side wall 421 and the bracket second side wall 422, and a second assembly part 424 is formed within the bracket second side wall 422. The bracket first side wall 421 and the bracket second side wall 422 extend circumferentially parallel to the overall outer circumferential contour shape of the bracket 420 to form a closed structure, for example, but not limited to, a closed oval, circle, square, rectangle, etc. The bracket first side wall 421 and the bracket second side wall 422 that extend closed form a first assembly part 423 and a second assembly part 424 of the receiving cap first protrusion part 412 and the second protrusion part 413, and serve to fix and support the entire cap.

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

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

[0168] In some embodiments, the bracket 420 further includes a button plate 427 connected via at least one elastic arm 426, the button plate being configured to move downward under the action of an external force to perform a pressing function, and the elastic arm 426 being configured to restore the button plate 427. As shown in FIG. 44, the button plate 427 is usually located inside the bracket and includes a pair of symmetrically arranged buttons. The button plate 427 includes a button plate head 4271 that contacts the cap abutment portion 4171 and a button plate tail 4272 that presses and contacts the components of the circuit board 105. The width of the button plate head 4271 is usually larger than the width of the button plate tail 4272. If the width of the button plate head 4271 is large, it is easy to receive the pressing force, and if the button plate tail 4272 is small, it can accurately contact and press the element and avoid erroneous pressing. The button plate 427 is connected to the inner edge of the bracket 420 via an elongated elastic arm 426, and one or more elongated elastic arms 426 are provided around the button plate 427 to provide the button plate 427 with sufficient pressing and restoring elastic force.

[0169] In some embodiments, as shown in Figures 46 and 47, the cap 410 includes a pressing body 411 located approximately at the center of the cap 410, and a first protrusion 412 and a second protrusion 413 extending downward around the pressing body 411, the first protrusion 412 and the second protrusion 413 extending parallel to the contour of the pressing body 411 along the circumferential direction to form a closed structure, where the first protrusion 412 and the second protrusion 413 are fitted to the first assembly part 423 and the second assembly part 424, respectively, when the cap 410 is assembled to the bracket 420. In order to fit the internal step structure between the first assembly part 423 and the second assembly part 424, the length of the first protrusion 412 extending downward is greater than the length of the second protrusion 413 extending downward. The first protrusion 412 and the second protrusion 413 are interference-assembled with the first assembly part 423 and the second assembly part 424, respectively, improving the stability and sealing performance of the cap assembly.

[0170] In some embodiments, as shown in Fig. 46, a third protrusion 414 is provided on the upper surface of the cap 410, connecting the first protrusion 412 and the second protrusion 413 and extending upward around the pressing body 411. The third protrusion 414 is parallel to the contour of the pressing body 411 and extends circumferentially to form a closed structure. The cap 410 further includes a first groove 415 and a second groove 416 extending along either side of the third protrusion 414, and the depth of the first groove 415 is greater than the depth of the second groove 416. As shown in Figures 49 and 50, Figure 50 is an enlarged bottom view of part D of the cover in Figure 49, where cover 1000 includes a button mounting hole 1002, and said pressing body 411 is assembled into said button mounting hole 1002, at which point a downwardly extending edge 1004 is provided at the edge of the button mounting hole 1002, and said edge is inserted into the button mounting hole 1002 from bottom to top together with the pressing body 411, thereby being inserted into the second groove 416 around the pressing body 411. The edge 1004 constitutes one of the waterproof ribs of the cover 1000, and the side wall of the edge 1004 includes at least one bump, and the pressing body 411 is interference assembled into the button mounting hole 1002 to achieve a sealed connection, thereby realizing the effects of waterproofing and preventing light leakage. Further, in some embodiments, the cover 1000 includes a waterproof rib 1003 extending downward around the button mounting hole 1002, the waterproof rib 1003 is assembled to the first groove 415, and a side wall of the waterproof rib 1003 includes at least one bump, so that the waterproof rib 1003 is interference-assembled to the first groove 415. When the pressing body 411 is inserted into the button mounting hole 1002, the edge of the button mounting hole 1002 is inserted into the second groove 416 around the pressing body 411, and the waterproof rib 1003 is also interference-inserted into the first groove 415, so that the downward extending length of the waterproof rib 1003 is greater than the length of the edge of the button mounting hole 1002, so that the pressing body 411 and the button mounting hole 1002 are further sealed and connected, and good waterproof and light leakage prevention effects are achieved.

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

[0172] In some embodiments, as shown in Fig. 47 and Fig. 48, a downwardly extending light-shielding arm 418 is provided between the two recesses 417 provided at a distance from each other. The light-shielding arm 418 may be made of an opaque material or may be formed by applying an opaque material, and after the components on the circuit board 105 are pressed by the button plates 427 on both sides, optical interference is formed between the optical elements associated with the pressing operation, affecting the user's acquisition of optically presented information. The light-shielding arm 418 may be integrally molded with the cap, or may be later processed and synthesized by bonding, engagement, etc., but is not limited thereto.
