[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202311084035.3 filed on August 25, 2023, and the contents of the above-mentioned Chinese patent application disclosure are hereby cited in their entirety as part of this disclosure. Technical Field

[0003] The present disclosure relates to the technical field of cleaning equipment, and in particular to a dust collection box, a self-moving cleaning equipment and a system. Background Art

[0004] In recent years, with the development of science and technology, a variety of cleaning products have emerged one after another. These cleaning products have reduced the burden of cleaning and sweeping, met people's needs, and provided great convenience to people's lives. Among them, automatic cleaning equipment is popular among people for its highly intelligent features.

[0005] Currently, all robot vacuums on the market are equipped with a dust collection charging station that can both charge and collect dust. The station has a dedicated recycling area for the robot to charge and collect dust simultaneously. When the robot vacuum is charging or collecting dust, debris from the robot's internal dust box is sucked into the charging station. The charging station has a larger recycling bin that can store debris, and the user only needs to clean it. During the vacuuming process, debris easily covers the filter.

[0006] Summary of the Invention

[0007] The purpose of this disclosure is to provide a dust collection box, a self-propelled cleaning device, and a system that can solve the technical problem of garbage easily clogging the filter in the related art. The specific solution is as follows:

[0008] According to a first aspect of the present disclosure, a dust collection box is provided, comprising: a first side wall, provided with a collection port; a second side wall, the second side wall being arranged opposite to the first side wall, the second side wall being configured to cause the cleaned object to fall into the dust collection box under the action of gravity after being hit by the cleaned object; a third side wall, provided with an air outlet, the angle between the third side wall and the first side wall being a first angle, the first angle being greater than 90 degrees.

[0009] In some embodiments, the second sidewall is arranged non-parallel to the first sidewall.

[0010] In some embodiments, the dust box further includes: a fourth side wall, the fourth side wall being disposed between the second side wall and the first side wall, an air intake being provided on the fourth side wall, and an angle between the fourth side wall and the first side wall being less than or equal to 90 degrees.

[0011] In some embodiments, the dust box further includes: an air suction baffle, which is arranged at the air suction port, and the air suction baffle is rotatably connected to the fourth side wall; when the dust box is in a first state, the air suction baffle covers the air suction port; when the dust box is in a second state, the air suction baffle is opened.

[0012] In some embodiments, when the air suction baffle is opened, the air suction direction is parallel to the plane where the second side wall is located and is toward the third side wall.

[0013] In some embodiments, the dust box further includes: a fifth side wall, wherein the fifth side wall is disposed between the second side wall and the third side wall.

[0014] In some embodiments, a connection between the fifth sidewall and the second sidewall is configured as a rounded corner.

[0015] In some embodiments, a projection of the second sidewall in the direction of the first sidewall is within the range of the first sidewall.

[0016] According to another aspect of the present disclosure, a self-moving cleaning device is provided, comprising a dust collection box as described in any one of the above technical solutions.

[0017] According to another aspect of the present disclosure, the present disclosure provides a self-moving cleaning system, comprising the self-moving cleaning device as described in any one of the above technical solutions.

[0018] Compared with the related art, the above solution of the embodiment of the present disclosure has at least the following beneficial effects:

[0019] In the disclosed dust collection box, when the dust collection fan is activated, garbage enters the dust collection chamber from the collection port. Due to inertia, it continues to move straight ahead, impacting the second sidewall. Gravity forces the garbage to settle directly to the bottom of the dust box, while air is discharged from the robot through the air outlet. This utilizes the principle of gravity dust removal, and the angle between the first and third sidewalls is greater than 90 degrees, forming an obtuse angle. This allows the point where garbage impacts the third sidewall to maintain a certain distance from the filter, preventing it from sticking to the filter and affecting its lifespan and dust collection efficiency.

[0031] To make the objectives, technical solutions, and advantages of the present disclosure more clear, the present disclosure will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only a portion of the embodiments of the present disclosure, rather than all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative effort are intended to fall within the scope of protection of the present disclosure.

[0032] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the present disclosure. The singular forms "a," "an," "the," and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include plural forms, and unless the context clearly indicates otherwise, "a plurality" generally includes at least two.

[0033] It should be understood that the term "and / or" used in this document is merely a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, the characters "three" in this document generally indicate that the associated objects are in an "or" relationship.

[0034] It should be understood that although the terms "first," "second," "third," etc. may be used to describe "...," these "..." should not be limited to these terms. These terms are merely used to distinguish "...." For example, "first..." could also be referred to as "second...", and similarly, "second..." could also be referred to as "first..." without departing from the scope of the present invention.

[0035] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to the determination" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)," depending on the context.

[0036] It should also be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or device comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or device.

[0037] When recharging or collecting dust, the related art self-propelled cleaning device sucks debris from the dust box inside the self-propelled cleaning device into the dust charging station 700. The dust charging station 700 has a larger recycling bin that can store debris, and the user only needs to clean the recycling bin. During the vacuuming process, the self-propelled cleaning device can easily accumulate debris on the filter, even causing the filter to become blocked, resulting in reduced dust collection efficiency and incomplete collection of localized debris.

[0038] The present disclosure provides a dust box 670, a self-moving cleaning device and a system, wherein the dust box may include: a first side wall 100, provided with a collection port 20; a second side wall 200, wherein the second side wall 200 is arranged opposite to the first side wall 100, and the second side wall 200 is configured to be hit by the cleaned object (cleaned garbage) so that the cleaned object falls into the dust box 670 under the action of gravity; a third side wall 300, provided with an air outlet, and the angle between the third side wall 300 and the first side wall 100 is a first angle α1, and the first angle α1 is greater than 90 degrees.

[0039] The technical solution of the present disclosure can solve at least one of the technical problems mentioned above. The optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0040] FIG1 is a schematic structural diagram of a self-moving cleaning device according to some embodiments of the present disclosure.

[0041] FIG. 2 is a schematic diagram of the bottom structure of the self-moving cleaning device shown in FIG. 1 .

[0042] As shown in Figures 1 and 2, a self-moving cleaning device 600, such as a sweeping robot, may include steering wheels 620 and drive wheels 630. The self-moving cleaning device 600 can move on a supporting surface, such as the ground, under the action of the steering wheels 620 and the drive wheels 630. Optionally, the self-moving cleaning device 600 can move along a pre-set route, and in certain circumstances, such as when the self-moving cleaning device 600 itself is low on power, its dust box is full of garbage, and the cleaning task is completed, the self-moving cleaning device 600 can move back to the dust collection charging station to complete charging or unload the garbage into the dust collection container.

[0043] The self-mobile cleaning device 600 may also include charging electrodes 640, configured to electrically connect to the dust collection charging station to charge the self-mobile cleaning device 600 after the self-mobile cleaning device 600 returns to the dust collection charging station. As shown in Figure 2, in some embodiments, the charging electrodes 640 are disposed on the bottom surface of the self-mobile cleaning device 600, for example, two charging electrodes 640, one on each side of the steering wheel 620. Those skilled in the art will appreciate that the above is merely an example of the number and location of the charging electrodes, and this disclosure does not specifically limit the number and location of the charging electrodes.

[0044] The self-mobile cleaning device 600 can also include a cleaning module 610, for example, a dry cleaning module. The cleaning module 610 is configured to clean at least a portion of a support surface, such as the ground, when the self-mobile cleaning device 600 moves on the support surface, such as the ground. In certain embodiments, as shown in Figure 2, the cleaning module 610 is, for example, arranged between two driving wheels 630. The cleaning module 610 can specifically include a frame 612 and a roller brush 611 arranged in the frame 612, and a plurality of scraping strips 6111 are provided on the periphery of the roller brush 611. The frame 612 has a vent 6121, which exposes at least a portion of the roller brush 611.

[0045] When the self-mobile cleaning device 600 performs a cleaning operation, the roller brush 611 rotates, and the scraper bar 6111 exposed on it by the frame 612 can contact the ground. At the same time, the fan in the self-mobile cleaning device 600, such as a dust suction fan, generates an airflow that enters the frame 612 through the vent 6121. Under the action of the scraper bar 6111 and the airflow, the garbage will enter the frame 612 through the vent 6121 and then be collected in the dust box of the self-mobile cleaning device 600. The vent 6121 also serves as a garbage circulation port. That is to say, when the self-mobile cleaning device 600 performs a cleaning operation, the vent 6121 serves as the dust suction port of the self-mobile cleaning device 600.

[0046] FIG3 is a schematic structural diagram of a dust collection box and a self-moving cleaning device that are not assembled together according to some embodiments of the present disclosure.

[0047] As shown in Figure 3, the self-mobile cleaning device 600 also includes a dust suction fan 660. Since the dust suction fan 660 is located inside the self-mobile cleaning device 600, it is not shown in the figure. The dust suction fan 660 is configured to provide a suction power source for the self-mobile cleaning device 600 during cleaning operations, generating an airflow. When the self-mobile cleaning device 600 performs a cleaning operation, the airflow generated by the dust suction fan 660 drives garbage into the frame 612 through the vent 6121 and is then collected in the dust collection box 670 of the self-mobile cleaning device 600.

[0048] The self-mobile cleaning device 600 has a storage space 650, which is configured to accommodate the dust box 670. A second opening 651 and a vent 652 are provided on the side wall of the storage space 650, and both the second opening 651 and the vent 652 are connected to the outside world. When the self-mobile cleaning device 600 is performing cleaning work, garbage enters the dust box 670 through the vent 6121 and the second opening 651; the vent 652 is configured to allow external air to enter the dust box 670 through the vent 652 when the self-mobile cleaning device 600 returns to the dust collection charging station 700 for dust collection.

[0049] FIG4 is a schematic structural diagram of a dust collection charging pile according to some embodiments of the present disclosure.

[0050] The dust collection charging pile 700 integrates a charging pile and a dust collection pile, and is configured to provide energy supply and garbage collection for the self-moving cleaning equipment.

[0051] As shown in Figure 4, the dust collection charging pile 700 includes a dust collection charging pile base 710 and a dust collection charging pile body 720. The dust collection charging pile body 720 is configured to charge the self-mobile cleaning device 600 and collect garbage in the dust box 670 of the self-mobile cleaning device 600, and is arranged on the dust collection charging pile base 710. The dust collection charging pile body 720 includes a dust collection container 722 and a dust collection fan 723. The dust collection container 722 is, for example, in the form of a drum, and is configured to recycle garbage in the dust box 670 of the self-mobile cleaning device 600. The dust collection fan 723 is connected to the air outlet provided in the dust collection container 722 to provide power to recycle the garbage in the dust box 670 of the self-mobile cleaning device 600 into the dust collection container 722.

[0052] The dust collection charging pile 700 includes a charging connector 721 and a dust suction port 711. The charging connector 721 is configured to supply energy to the self-mobile cleaning device 600. The dust suction port 711 is configured to connect with the dust outlet of the self-mobile cleaning device 600 (when the self-mobile cleaning device 600 discharges dust into the dust collection charging pile 700, the vent 6121 in the self-mobile cleaning device 600 serves as the dust outlet). The garbage in the dust box 670 of the self-mobile cleaning device 600 enters the dust collection container 722 of the dust collection charging pile body 720 through the dust suction port 711. For example, as shown in Figure 4, the charging connector 721 is provided on the dust collection charging pile body 720, and the dust suction port 711 is provided on the dust collection charging pile base 710. In some embodiments, as shown in Figure 4, a sealing rubber gasket 712 is further provided around the dust suction port 711 to seal the dust suction port 711 and the dust outlet of the self-mobile cleaning device 600 after docking to prevent garbage leakage.

[0053] The air inlet of the dust collecting container 722 is connected to the dust suction port 711 through the dust collecting air path 713. Under the action of the airflow generated by the dust collecting fan 723, the garbage in the dust collecting box 670 in the self-moving cleaning device 600 can pass through the ventilation port 6121 in the self-moving cleaning device 600 and be collected in the dust collecting container 722 via the dust collecting air path 713.

[0054] FIG5 is a schematic diagram of a scene after a mobile cleaning device returns to a dust collection charging station according to some embodiments of the present disclosure.

[0055] As shown in Figure 5, when the self-mobile cleaning device 600, such as a sweeping robot, returns to the dust collection charging pile 700 after cleaning, the self-mobile cleaning device 600 will move along the first direction X to the dust collection charging pile base 710, so that the charging electrode 640 on the self-mobile cleaning device 600 is electrically connected to the charging connector 721 to charge the self-mobile cleaning device 600, and the dust outlet of the self-mobile cleaning device 600, that is, the ventilation port 6121, is docked with the dust suction port 711 of the dust collection charging pile 700 to transfer the garbage in the dust box 670 of the self-mobile cleaning device 600 to the dust collection container 722 of the dust collection charging pile 700.

[0056] Figure 6 shows a schematic diagram of a dust collection box according to some embodiments of the present disclosure, illustrating the direction of airflow in the dust collection box when the automatic cleaning device performs a cleaning operation. Figure 7 shows a schematic diagram of a dust collection box according to some embodiments of the present disclosure, illustrating the direction of airflow in the dust collection box when the automatic cleaning device returns to the dust collection pile to collect dust. Figure 8 shows a schematic diagram of a dust collection box according to some embodiments of the present disclosure, illustrating the relative angular relationship between the side walls.

[0057] As shown in Figures 6-8, according to the first aspect of the present disclosure, a dust collection box 670 is provided, which may include: a first side wall 100, provided with a collection port 20; a second side wall 200, the second side wall 200 being arranged opposite to the first side wall 100, and the second side wall 200 being configured to be hit by the cleaned object (cleaned garbage) so that the cleaned object falls into the dust collection box 670 under the action of gravity; a third side wall 300, provided with an air outlet, the air outlet being used to set a filter 310; the end of the third side wall 300 away from the second side wall 200 is connected to the first side wall 100, and the angle between the third side wall 300 and the first side wall 100 is a first angle α1, and the first angle α1 is greater than 90 degrees. In some embodiments, the space inside the first side wall 100, the second side wall 200 and the third side wall 300 is a dust collection chamber 10. In the dust box 670 of the present disclosure, under the action of the dust suction blower 660, when garbage enters the dust collection chamber 10 from the collection port 20, it will continue to move straight due to inertia, impacting the second side wall 200. Under the action of gravity, it will directly settle to the bottom of the dust box, and the air will be discharged from the robot through the air outlet. The present disclosure utilizes the principle of gravity dust removal, and the angle between the first side wall 100 and the third side wall 300 is greater than 90 degrees, forming an obtuse angle. The point where the garbage impacts the third side wall 300 can be kept a certain distance from the filter, preventing the garbage from sticking to the filter and affecting the filter life and dust collection efficiency.

[0058] Scenarios in actual applications may include the following:

[0059] Scenario 1, dust collection: During the cleaning process of the self-moving cleaning device 600, the dust box 670 is placed at the corresponding position of the self-moving cleaning device 600. The dust suction fan 660 in the self-moving cleaning device 600 draws air at the end of the filter 310 away from the dust collecting chamber 10. The power of the dust suction fan 660 is not enough to open the air suction baffle 410. At this time, the air suction baffle 410 is closed. Due to the suction of the dust suction fan 660, the garbage collected during cleaning will follow the air flow from the collection port 20 into the dust collecting chamber 10. Due to inertia, the garbage will continue to move straight and hit the second side wall 200, losing its forward kinetic energy. Under the action of gravity, it will directly settle to the bottom of the dust box. The air will be discharged from the self-moving cleaning device 600 through the air outlet, and the garbage will remain in the dust collecting chamber 10.

[0060] Scenario 2, dust collection: When the self-moving cleaning device 600 returns to the dust collection charging pile 700 (when charging, replenishing water, changing water or collecting dust), the dust collection box 670 is placed at the corresponding position of the self-moving cleaning device 600, and the collection port 20 corresponds to the dust collection fan 723 of the dust collection charging pile 700. The dust collection fan 723 and the dust suction fan 660 work at the same time. Due to the negative pressure in the dust collecting chamber 10, the air intake baffle 410 opens, and the air flow enters from the air intake port 30 and blows in the direction of the fifth side wall 500 along the parallel direction of the second side wall 200. The wind direction changes after passing through the fifth side wall 500. Since the wind force of the dust collection fan 723 is greater than the wind force of the dust suction fan 660, the sucked air forms an annular cyclone, which can more effectively carry away the garbage in the dust collecting chamber 10. Compared with the original rectangular dust box, there is no dead corner for garbage left, thereby improving the dust collection efficiency.

[0061] In some embodiments, the second sidewall 200 is non-parallel to the first sidewall 100. In some embodiments, the angle between the second sidewall 200 and the first sidewall 100 is a second angle α2, and the second angle α2 is less than 90 degrees (as shown in Figure 8). To ensure that garbage entering the dust collection chamber 10 during vacuuming hits the second sidewall 200, loses forward kinetic energy, and settles directly to the bottom of the dust box under the action of gravity, the second angle α2 is less than 90 degrees.

[0062] In some embodiments, the filter 310 is a detachable structure. The filter 310 can be removed from the third side wall 300 to facilitate subsequent maintenance, cleaning, and replacement.

[0063] As shown in Figures 6-8, in some embodiments, the dust collection box may further include a fourth sidewall 400, disposed between the second sidewall 200 and the first sidewall 100. The fourth sidewall 400 is provided with an air intake 30, with the angle between the fourth sidewall 400 and the first sidewall 100 being less than or equal to 90 degrees. Air drawn in through the air intake 30 forms an annular cyclone, which more effectively removes waste from the dust collection chamber 10. Compared to conventional rectangular dust boxes, this eliminates dead corners where waste can accumulate, thereby improving dust collection efficiency.

[0064] In some embodiments, the dust box 670 may further include: an air suction baffle 410 , which is disposed at the air suction port 30 , and the air suction baffle 410 is rotatably connected to the fourth side wall 400 .

[0065] In some embodiments, when the dust box 670 is in the first state, that is, when the automatic cleaning device is in a non-dust collecting state, the suction baffle 410 covers the suction port 30 .

[0066] As shown in Figures 6-8, in some embodiments, when the dust box 670 is in the second state, that is, when the automatic cleaning device returns to the dust collection pile to collect dust, the suction damper 410 is opened. The dust box 670 is placed in a corresponding position on the self-moving cleaning device 600, and the collection port 20 corresponds to the dust collection fan 723 of the dust collection charging pile 700. The dust collection fan 723 and the dust suction fan 660 operate simultaneously. Due to the negative pressure in the dust collection chamber 10, the suction damper 410 opens, and air enters through the suction port 30 and blows along the direction parallel to the second side wall 200 toward the fifth side wall 500. The wind direction changes after passing through the fifth side wall 500. Because the wind force of the dust collection fan 723 is greater than the wind force of the dust suction fan 660, the sucked air forms an annular cyclone, which can more effectively remove garbage from the dust collection chamber 10. Compared with the original rectangular dust box, there is no dead corner left for garbage, thereby improving dust collection efficiency.

[0067] The first state is the state in which the self-moving cleaning device 600 is vacuuming, that is, the state in which the automatic cleaning robot is cleaning.

[0068] The second state is the state in which the self-mobile cleaning device 600 collects dust, that is, the state in which the automatic cleaning robot transfers the garbage in the dust collecting chamber 10 to the dust collecting bin in the dust collecting charging pile 700 on the dust collecting charging pile 700 .

[0069] In some embodiments, when the air suction baffle 410 is opened, the air suction baffle 410 forms a third angle α3 with the fourth sidewall 400 .

[0070] In some embodiments, the third angle α3 and the second angle α2 are complementary to each other.

[0071] In some embodiments, the first angle is 90 degrees minus the second angle α2.

[0072] In some embodiments, the third angle α3 is less than or equal to the first angle.

[0073] When the air intake baffle 410 is parallel to the second sidewall 200, the third angle α3 is complementary to the second angle. When the third angle α3 is greater than the first angle, the airflow direction is more inclined toward the third sidewall 300. When the third angle α3 is less than the first angle, the airflow direction is more inclined toward the second sidewall 200.

[0074] The airflow direction is biased toward the second side wall 200 to form an annular cyclone.

[0075] As shown in Figures 6-8, the airflow sucked into the dust collecting chamber 10 approaches the second side wall 200, and forms an annular cyclone through the rebound of the second side wall 200 or the third side wall 300, which can more effectively carry away the garbage in the dust collecting chamber 10. Compared with the original rectangular dust box, there is no dead corner left for garbage, thereby improving the dust collection efficiency.

[0076] In some embodiments, when the air suction baffle 410 is opened, the air suction direction is parallel to the plane where the second side wall 200 is located and is toward the third side wall 300 .

[0077] In some embodiments, the dust collecting box 670 may further include: a fifth side wall 500 , wherein the fifth side wall 500 is disposed between the second side wall 200 and the third side wall 300 .

[0078] In some embodiments, the space inside the first side wall 100, the second side wall 200, the third side wall 300, the fourth side wall 400 and the fifth side wall 500 is the dust collecting chamber 10; that is, the space enclosed by the first side wall 100, the second side wall 200, the third side wall 300, the fourth side wall 400 and the fifth side wall 500 is the dust collecting chamber 10.

[0079] In some embodiments, the connection between the fifth sidewall 500 and the second sidewall 200 is rounded. The first turn encountered by the airflow entering the dust collection chamber 10 from the air intake 30 is at the connection between the fifth sidewall 500 and the second sidewall 200. Therefore, the rounded corner is set here, which makes it easier for the airflow to form an annular cyclone and can effectively reduce the loss of airflow kinetic energy. It can more effectively remove the garbage in the dust collection chamber 10 without leaving any dead corners, thereby improving dust collection efficiency.

[0080] In some embodiments, the fifth sidewall 500 is curved and has a depression on a side close to the dust collecting chamber 10. The fifth sidewall 500 is designed to curve and protrude outward from the dust collecting chamber 10, which can make it easier for the airflow to form an annular cyclone and effectively reduce the loss of airflow kinetic energy. It can more effectively remove the garbage in the dust collecting chamber 10 without leaving any dead corners for garbage, thereby improving the dust collection efficiency.

[0081] As shown in FIG. 6-8 , in some embodiments, the angle formed by the third side wall 300 and the first side wall 100 and close to the dust collecting chamber 10 is the first angle α1.

[0082] In some embodiments, an angle formed by an extension line of the second side wall 200 and an extension line of the first side wall 100 and close to the dust collecting chamber 10 is the second angle α2.

[0083] In some embodiments, an angle formed by the air suction baffle 410 and the fourth sidewall 400 and away from the first sidewall 100 is the third angle α3.

[0084] FIG9 shows a schematic diagram of a dust box according to some embodiments of the present disclosure, wherein the direction of movement of the airflow in the dust box when the automatic cleaning device performs a cleaning operation is shown.

[0085] As shown in FIG. 9 , in some embodiments, a dust shield 510 is provided on the fifth inner wall, and the dust shield 510 extends along the direction of the collecting port 20 .

[0086] In some embodiments, the corners of the inner wall of the dust collection chamber 10 may be rounded. The airflow entering the dust collection chamber 10 from the air inlet 30 encounters a turn, which reduces the kinetic energy of the airflow. Therefore, the rounded corners make it easier for the airflow to form an annular cyclone, effectively reducing the loss of kinetic energy of the airflow. This allows the dust in the dust collection chamber 10 to be more efficiently removed, leaving no dead corners for garbage, and improving dust collection efficiency.

[0087] In some embodiments, the projection of the second sidewall 200 in the direction of the first sidewall 100 is within the range of the first sidewall 100. This can increase the distance between the second sidewall 200 and the third sidewall 300, that is, the point where the sucked-in garbage hits the second sidewall 200 can be a certain distance away from the filter, preventing garbage from sticking to the filter and affecting the filter life and dust collection efficiency.

[0088] In some embodiments, the dust box 670 may further include a top plate, which is perpendicular to the first side wall 100, the second side wall 200, the third side wall 300, the fourth side wall 400, and the fifth side wall 500. When the self-moving cleaning device 600 is in use, the top plate faces upward.

[0089] In some embodiments, the dust box 670 may further include a bottom plate, a top plate perpendicular to the first side wall 100, the second side wall 200, the third side wall 300, the fourth side wall 400, and the fifth side wall 500, the bottom plate being disposed opposite the top plate. When the self-moving cleaning device 600 is in use, the bottom plate faces downward.

[0090] In some embodiments, a guide groove is provided on the top plate in the dust collecting chamber 10 .

[0091] In some embodiments, the guide groove is annular.

[0092] In some embodiments, one end of the guide groove close to the second side wall 200 is consistent with the air intake direction and is located above the air intake flow.

[0093] In some embodiments, there are multiple guide grooves, and the multiple guide grooves are arranged in parallel; the outermost guide groove is close to the end of the second side wall 200 and is consistent with the suction direction and is located above the suction airflow.

[0094] In some embodiments, the guide groove is spiral-shaped.

[0095] In some embodiments, the outermost inlet of the guide groove is arranged above the air suction baffle 410.

[0096] By arranging the guide groove in the dust collecting chamber 10, the airflow sucked into the dust collecting chamber 10 can be moved in the direction of the guide groove to a certain extent, so that the airflow sucked into the dust collecting chamber 10 forms an annular cyclone, which can more effectively carry away the garbage in the dust collecting chamber 10. Compared with the original rectangular dust box, there is no dead corner left for garbage, thereby improving the dust collection efficiency.

[0097] According to a second aspect of the present disclosure, a self-moving cleaning device 600 is provided, which may include a dust collection box 670 as described in any one of the above technical solutions.

[0098] According to a third aspect of the present disclosure, a self-moving cleaning system is provided, which may include the self-moving cleaning device 600 as described in any one of the above technical solutions.

[0099] In some embodiments, the self-moving cleaning system may further include: a dust collection charging pile 700, which responds to the self-moving cleaning device 600 as described in any of the above technical solutions, and the garbage in the dust box 670 of the self-moving cleaning device 600 is collected into the dust collection bin of the dust collection charging pile 700 through the collection port 20.

[0100] In some embodiments, the dust collection charging pile 700 may include: a dust collection fan 723, which is used to suck out the garbage in the dust collection chamber 10 through the collection port 20, and the suction force of the dust collection fan 723 is greater than the suction force of the dust suction fan 660.

[0101] The present disclosure is intended to protect a dust box 670, a self-propelled cleaning device, and a system. The dust box 670 may include: a first side wall 100 having a collection port 20; a second side wall 200 disposed opposite the first side wall 100, the second side wall 200 being configured to cause the cleaned material (cleaned garbage) to fall into the dust box 670 under the action of gravity after being impacted by the second side wall 200; and a third side wall 300 having an air outlet, the angle between the third side wall 300 and the first side wall 100 being a first angle α1, the first angle α1 being greater than 90 degrees. In the dust box 670 of the present disclosure, when garbage enters the dust collection chamber 10 from the collection port 20 under the action of the dust suction fan 660, it will continue to move straight due to inertia and impact the second side wall 200. Under the action of gravity, it will directly settle to the bottom of the dust box, and air will be discharged from the robot through the air outlet. The present invention utilizes the principle of gravity dust removal, and the angle between the first side wall 100 and the third side wall 300 is greater than 90 degrees, forming an obtuse angle. The impact point of the garbage on the third side wall 300 can be at a certain distance from the filter, thereby preventing the garbage from sticking to the filter and affecting the filter life and dust collection efficiency.

[0102] It should be understood that the above-described specific embodiments of the present disclosure are merely illustrative of or explanation of the principles of the present disclosure and do not constitute limitations on the present disclosure. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present disclosure shall be included within the scope of protection of the present disclosure. In addition, the claims appended to the present disclosure are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents of such scope and metes and bounds.
