Description

Technical Field

[0001] This invention relates to the field of robotic vacuum cleaners, and in particular to a dust collection box and a robotic vacuum cleaner using the dust collection box. Background Technology

[0002] Currently, in the dust collection bins of sweeping machines in related technologies, when collecting garbage, the garbage tends to accumulate beyond the dust collection opening of the dust collection bin, and this blocks the area inside the dust collection bin far from the dust collection opening from further containing the garbage, thus reducing the space utilization efficiency of the dust collection bin. Summary of the Invention

[0003] The main objective of this invention is to provide a dust collection box that improves the space utilization efficiency of the dust collection box.

[0004] To achieve the above objectives, the dust collection box proposed in this invention includes:

[0005] The box body is defined as having a first end and a second end arranged opposite to each other. The box body is provided with a dust collection chamber, a suction chamber, and an air outlet connecting the dust collection chamber and the suction chamber. The box body also has a dust collection port connecting to the dust collection chamber, the dust collection port being located near the first end of the box body.

[0006] A filter screen is disposed inside the housing and covers the air vent. The filter screen is located near the second end of the housing.

[0007] In one embodiment of the present invention, a center line is defined between the first end and the second end of the box body, and the filter screen has a center line parallel to the center line of the box body. The distance between the center line of the filter screen and the center line of the box body in the left-right direction is D1, where D1 is greater than or equal to 5 mm and less than or equal to 100 mm.

[0008] In one embodiment of the present invention, the dust collection port is defined to have a dust port centerline parallel to the centerline of the box body, and the distance between the dust port centerline and the centerline of the box body in the left-right direction is D2, where D2 is greater than or equal to 1 mm and less than or equal to 100 mm.

[0009] In one embodiment of the present invention, the box body is further provided with an air inlet communicating with the air suction chamber, and the air inlet is disposed near the first end of the box body.

[0010] In one embodiment of the present invention, the air intake is defined to have an air intake centerline parallel to the centerline of the box body, and the distance between the air intake centerline and the centerline of the box body in the left-right direction is the same as the distance between the dust outlet centerline and the centerline of the box body in the left-right direction.

[0011] In one embodiment of the present invention, the filter screen includes:

[0012] A primary filter, which is fixedly connected to the housing and covers the air vent; and

[0013] The secondary filter is detachably connected to the housing and covers the air vent. The primary filter and the secondary filter are distributed sequentially along the airflow direction of the air vent.

[0014] In one embodiment of the present invention, the primary filter and the housing are integrally formed.

[0015] In one embodiment of the present invention, the dust collection box further includes:

[0016] A grip, rotatably disposed on the housing; and

[0017] A limiting structure is provided, which is connected to the box body and the gripper, and can limit and fix the gripper when it is rotated to a preset angle.

[0018] In one embodiment of the present invention, the limiting structure includes:

[0019] The box body protrudes, and the box body protrusion is provided on the box body; and

[0020] A gripping protrusion is provided on the gripping member. When the gripping member is rotated to a preset angle, the side wall surface of the gripping protrusion abuts against the side wall surface of the box body protrusion, thereby limiting and fixing the gripping member to the box body.

[0021] The present invention also proposes a sweeping robot, including a dust collection box, the dust collection box comprising:

[0022] The box body is defined as having a first end and a second end arranged opposite to each other. The box body is provided with a dust collection chamber, a suction chamber, and an air outlet connecting the dust collection chamber and the suction chamber. The box body also has a dust collection port connecting to the dust collection chamber, the dust collection port being located near the first end of the box body.

[0023] A filter screen is disposed inside the housing and covers the air vent. The filter screen is located near the second end of the housing.

[0024] In use, the dust collection box of this invention draws air from the suction chamber of the box body, creating a negative pressure in the suction chamber and the dust collection chamber connected to it, thus drawing dust and other debris from the outside into the dust collection chamber. Then, a filter screen covering the connection between the suction chamber and the dust collection chamber filters the airflow, preventing larger debris particles from entering the dust collection chamber, while smaller particles are adsorbed onto the filter structure, thus completing the collection of dust and other debris.

[0025] Furthermore, when dust and other debris enter the dust collection chamber and accumulate to a certain amount near the dust collection port, the dust collection port of this design is located near the first end of the chamber, while the filter is located near the second end. This allows the suction force of the dust collection chamber at the second end of the chamber to be greater than that at the first end. This drives subsequent dust and debris entering the dust collection chamber towards the second end, where it accumulates until it reaches the first end. This gradual accumulation of dust and debris within the dust collection chamber, starting near the dust collection port, passing through the second end, and finally filling the first end, prevents excessive accumulation at the dust collection port and thus hinders further containment of debris in areas far from the port. This improves the space utilization efficiency of the dust collection chamber. Attached Figure Description

[0043] Please refer to Figure 1 This invention proposes a dust collection box 10, which can be applied to a sweeping robot 100.

[0044] Please refer to the reference. Figure 2 , Figure 3 as well as Figure 4 In one embodiment of the present invention, the dust collection box 10 includes a box body 11 and a filter screen 13; wherein, the box body 11 is defined to have a first end and a second end arranged opposite to each other, the box body 11 is provided with a dust collection chamber 111, a suction chamber 113, and an air passage 114 connecting the dust collection chamber 111 and the suction chamber 113, the box body 11 is also provided with a dust collection port 115 connecting the dust collection chamber 111, the dust collection port 115 is disposed near the first end of the box body 11; the filter screen 13 is disposed inside the box body 11 and covers the air passage 114, the filter screen 13 is disposed near the second end of the box body 11.

[0045] In one embodiment of the present invention, the box 11 is mainly used for collecting dust and other waste. Specifically, the box 11 can be drawn into the suction chamber 113 by a fan, creating a negative pressure in the suction chamber 113 and the dust collection chamber 111 to generate suction, thereby drawing dust and other waste into the dust collection chamber 111. The box 11 can be roughly rectangular in shape to make its shape more regular and easier to manufacture. In this case, one of the two opposite ends of the box 11 along its length is designated as the first end, and the other as the second end, ensuring that the left and right ends of the box 11 are opposite each other. The dust collection chamber 111 and the suction chamber 113 can be spaced apart along the height or width of the box 11. This application does not limit the specific distribution of the dust collection chamber 111 and the suction chamber 113. The size of the dust collection chamber 111 can be set larger than the size of the suction chamber 113, thereby increasing the accommodating space of the dust collection chamber 111 and increasing the capacity of the dust collection box 10 for waste. The material of the box body 11 can be plastic, such as ABS, POM, PS, PMMA, PC, PET, etc., to reduce the weight of the dust collection box 10 and facilitate its handling. Of course, this application is not limited to this. In other embodiments, the material of the box body 11 can also be metal, such as aluminum, aluminum alloy, copper, copper alloy, iron, stainless steel, to increase the strength of the box body 11 and extend its service life. The filter screen 13 is mainly used to block and filter the air outlet 114, so as to block and retain larger waste particles in the dust collection chamber 111, while smaller waste particles are adsorbed on the filter screen, reducing the possibility of waste particles moving with the airflow to the exhaust fan connected to the suction chamber 113, so as to ensure the normal and stable operation of the exhaust fan. The filter screen 13 can also be rectangular to better match the shape of the box 11, while having a larger filtration area to improve filtration efficiency. Furthermore, it should be noted that the filter screen 13 can have most of its area located at the second end of the box 11, with a small portion at the first end; alternatively, the entire area of ​​the filter screen 13 can be located at the first end of the box 11. Similarly, the dust collection port 115 can have most of its area located at the first end of the box 11, with a small portion at the second end; alternatively, the entire area of ​​the dust collection port 115 can be located at the first end of the box 11. In short, the filter screen 13 and the dust collection port 115 should be positioned slightly off-center from the box 11.

[0046] In use, the dust collection box 10 of the present invention draws air from the suction chamber 113 of the box body 11, creating a negative pressure in the suction chamber 113 and the dust collection chamber 111 connected to it, thereby drawing dust and other debris from the outside into the dust collection chamber 111. Then, the airflow is filtered by a filter screen 13 that blocks the connection between the suction chamber 113 and the dust collection chamber 111. This filters larger debris particles, preventing them from entering the dust collection chamber 111, while smaller particles are adsorbed onto the filter structure, thus completing the collection of dust and other debris.

[0047] Furthermore, when dust and other debris enter the dust collection chamber 111 and accumulate to a certain amount near the dust collection port 115, the dust collection port 115 of the dust collection box 10 in this solution is located near the first end of the box body, and the filter screen 13 is located near the second end of the box body. This allows the suction force of the dust collection chamber 111 at the second end of the dust collection box 10 for dust and other debris to be greater than that at the first end of the dust collection box 10. This drives the dust and other debris that subsequently enters the dust collection chamber to move and accumulate towards the second end of the dust collection box 10. After accumulating to a certain amount at the second end, the debris gradually accumulates to the first end of the box body 11. This allows dust and other debris to gradually accumulate and fill the dust collection chamber 111 from the position near the dust collection port 115, through the dust collection chamber 111 at the second end of the box body 11, and to the dust collection chamber 111 at the first end of the box body 11. This prevents excessive accumulation of dust and other debris at the dust collection port 115 of the dust collection box 10, which would block further containment of debris in the area of ​​the dust collection box 10 away from the dust collection port 115, thereby improving the space utilization efficiency of the dust collection box 10.

[0048] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of the present invention, a center line of the box body 11 is defined between the first end and the second end of the box body 11, and the filter screen 13 has a filter screen center line parallel to the center line of the box body 11. The distance between the filter screen center line and the center line of the box body 11 in the left-right direction is D1, where D1 is greater than or equal to 5 mm and less than or equal to 100 mm.

[0049] It is understandable that when the distance D1 between the center line of the filter screen and the center line of the box 11 in the left-right direction is less than 5mm, the distance between the second end of the filter screen 13 and the center of the box 11 is relatively small. This can easily shorten the distance that garbage can move with the airflow to the second end of the box 11, thus affecting the final amount of garbage collected by the dust collector. When the distance D1 between the center line of the filter screen and the center line of the box 11 in the left-right direction is greater than 100mm, the lengths of both the filter screen 13 and the box 11 need to be relatively long, which can easily increase the overall size of the dust collection box 10 and make installation inconvenient. Therefore, setting the distance D1 between the center line of the filter screen and the center line of the box 11 in the left-right direction to be greater than or equal to 5mm and less than or equal to 100mm ensures both the final amount of garbage collected by the dust collection box 10 and avoids the dust collection box 10 being too small and occupying too much space. The distance D1 between the center line of the filter screen and the center line of the box 11 in the left-right direction can be 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm, 100mm, etc., or any value within the above range. This application does not limit the specific value of the distance D1 between the center line of the filter screen and the center line of the box 11 in the left-right direction.

[0050] Please refer to the reference. Figure 4 and Figure 6 In one embodiment of the present invention, the dust collection port 115 is defined to have a dust port center line parallel to the center line of the box body 11. The distance between the dust port center line and the center line of the box body 11 in the left-right direction is D2, where D2 is greater than or equal to 1 mm and less than or equal to 100 mm.

[0051] It is understandable that when the distance D2 between the center line of the dust inlet and the center line of the box 11 in the left-right direction is less than 1mm, the center of the dust collection port 115 and the center of the box 11 are relatively close, meaning the distance between the dust collection port 115 and the second end of the box 11 is reduced. This makes it easy for garbage to accumulate at the second end of the box 11 and then quickly accumulate at the dust collection port 115, affecting the final amount of garbage that the dust collection box 10 can collect. When the distance D2 between the center line of the dust inlet and the center line of the box 11 in the left-right direction is greater than 100mm, the length of the box 11 needs to be relatively long, which may increase the overall size of the dust collection box 10 and make installation inconvenient. Therefore, setting the distance D2 between the center line of the dust inlet and the center line of the box 11 in the left-right direction to be greater than or equal to 1mm and less than or equal to 100mm ensures that the dust collection box can ultimately collect the maximum amount of garbage while avoiding the dust collection box 10 having a small overall size and occupying a large space. The distance D2 between the center line of the dust inlet and the center line of the box 11 in the left-right direction can be 1mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm, 100mm, etc., or any value within the above range. This application does not limit the specific value of the distance D2 between the center line of the dust inlet and the center line of the box 11 in the left-right direction.

[0052] Please refer to Figure 2 In one embodiment of the present invention, the box body 11 is further provided with an air inlet 116 communicating with the air suction chamber 113, and the air inlet 116 is disposed near the first end of the box body 11.

[0053] It is understandable that as the debris in the dust collection chamber 111 accumulates from one end of the box 11 near the dust collection port 115 and then gradually accumulates back to the first end, the suction port 116 is positioned near the first end of the box 11. This reduces the obstruction to airflow caused by the gradual accumulation of debris, ensuring relatively smooth airflow within the duct formed by the dust collection chamber 111, the air vent 114, the suction chamber 113, and the suction port 116. The suction chamber 113 can be located above the dust collection chamber 111, allowing debris and dust to remain within the dust collection chamber 111 under gravity, further reducing the possibility of debris and dust being moved to the exhaust fan by the airflow. Correspondingly, the suction port 116 can be positioned above the dust collection port 115.

[0054] Please refer to the reference. Figure 2 and Figure 6In one embodiment of the present invention, the air intake 116 is defined to have an air intake centerline parallel to the centerline of the box 11, and the distance between the air intake centerline and the centerline of the box 11 in the left-right direction is the same as the distance between the dust outlet centerline and the centerline of the box 11 in the left-right direction.

[0055] It is understandable that this arrangement allows the airflow in the dust collection chamber 111 to still flow quickly to the suction port 116 when the garbage accumulates from the second end of the box 11 to the dust collection port 115, and thus further ensures the smooth flow of air in the air duct.

[0056] Please refer to the reference. Figure 3 and Figure 4 In one embodiment of the present invention, the filter screen includes a primary filter screen 131 and a secondary filter screen 133. The primary filter screen 131 is fixedly connected to the housing 11 and covers the air vent 114; the secondary filter screen 133 is detachably connected to the housing 11 and covers the air vent 114. The primary filter screen 131 and the secondary filter screen 133 are distributed sequentially along the airflow direction of the air vent 114.

[0057] It is understandable that this setup allows for secondary filtration of the airflow passing through the air outlet 114 via the primary filter 131 and the secondary filter 133, thereby improving the filtration efficiency. Simultaneously, the primary filter 131 reduces the amount of dust and other debris adsorbed onto the secondary filter 133, thus reducing the frequency of cleaning the secondary filter 133. Furthermore, since the primary filter 131 is fixedly connected to the housing 11, while the secondary filter 133 is detachably connected to the housing 11, the primary filter 131 and the housing 11 are designed as a single unit, while the secondary filter 133 is independently installed within the housing 11. Therefore, the primary filter 131 and the secondary filter 133 in this filtration structure are not designed as a single unit. Compared to existing dust collection boxes 10, where the filter structure is typically a single unit requiring a filter support to hold the primary filter 131 and secondary filter 133 together, and further ultrasonically welded to form a single unit, the dust collection box 10 of this application eliminates the need for such a filter support in its structure and ultrasonic welding in its manufacturing process. This simplifies the composition and forming process of the filter 13, thereby reducing the manufacturing cost of the dust collection box 10.

[0058] In one embodiment of the present invention, the primary filter 131 and the housing 11 are integrally formed.

[0059] It is understandable that making the primary filter 131 and the housing 11 into a single structure eliminates the need for connecting structures, simplifying the manufacturing process and further reducing the manufacturing cost of the dust collection box 10. Furthermore, the integrated structure improves the sealing of the connection between the primary filter 131 and the housing 11, ensuring the airtightness of the dust collection chamber 111 and the suction chamber 113. Simultaneously, the integrated structure also improves the stability of the connection between the primary filter 131 and the housing 11, reducing the possibility of the primary filter 131 detaching from the housing 11 due to airflow impact at the air outlet 114. Of course, it should be noted that this application is not limited to this; in other embodiments, the primary filter 131 can also be glued to the housing 11. Additionally, the primary filter 131 and the secondary filter 133 can be of the same shape and size and arranged opposite each other in the vertical direction. Furthermore, the primary filter 131 can be a mesh screen, and the secondary filter 133 can be a HEPA filter, so that smaller debris particles can be adsorbed through the primary filter 131, and even smaller debris particles can be adsorbed through the secondary filter 133. Of course, this application is not limited to this; in other embodiments, the primary filter 131 can also be a cotton swab filter, and the secondary filter 133 can also be an activated carbon filter, as long as the area of ​​the filter pores of the primary filter 131 is smaller than the area of ​​the filter pores of the secondary filter 133.

[0060] In one embodiment of the present invention, the box body 11 includes a box body 117, a partition 118, and a box cover 119. The box body 117 is provided with a filter installation port 1171. The partition 118 is disposed inside the box body 117 and divides the space inside the box body 117 into a dust collection chamber 111 and an air suction chamber 113. An air outlet 114 is disposed on the partition 118 and can be arranged opposite to the filter installation port 1171. The box cover 119 is detachably disposed on the box body 117 and covers the filter installation port 1171. The primary filter 131 is fixedly connected to the partition 118, and the secondary filter 133 is clamped and fixed by the box cover 119 and the partition 118.

[0061] It is understood that the secondary filter 133 is clamped and fixed by the box cover 119 and the partition 118, so that when the secondary filter 133 is placed into the partition 118 through the filter installation port 1171, closing the box cover 119 can complete the limiting and locking of the secondary filter 133; when the box cover 119 is opened, the secondary filter 133 can be unlocked. That is, the limiting and locking or unlocking of the box cover 119 and the secondary filter 133 can be completed in one go, thereby improving the convenience of using the dust collection box 10. The box body 117 has a first end and a second end that are arranged opposite to each other, and the primary filter 131 and the secondary filter 133 are arranged near the second end of the box body 117; while the dust collection port 115 and the air intake port 116 are both arranged in the box body 117 and near the first end of the box body 117. Alternatively, the primary filter 131 can be fixedly connected to the upper surface of the partition 118, and the secondary filter 133 abuts against the upper surface of the primary filter 131, meaning the partition 118 indirectly supports the secondary filter 133 and serves as the lid. Conversely, the primary filter 131 can also be fixedly connected to the lower surface of the partition 118, and the secondary filter 133 abuts against the upper surface of the partition 118, meaning the partition 118 directly supports both the primary and secondary filters. The lid 119 can use protruding ribs on its bottom edge to secure and limit the edge of the secondary filter 133.

[0062] In one embodiment of the present invention, the box cover plate 119 has a rotating end and a fixed end arranged opposite to each other. The rotating end of the box cover plate 119 is rotatably connected to the box body 117, and the fixed end of the box cover plate 119 is detachably connected to the box body 117.

[0063] It is understood that the cover plate 119 is rotatably connected to the body plate 117, so that the cover plate 119 remains connected to the body plate 117 even after being opened, eliminating the need for separate placement and further improving the convenience of using the dust collection box 10. The cover plate 119 and the body plate 117 can be rotatably connected directly through a combination of a cover hinge and a cover hole; that is, the cover plate 119 has one of a cover hinge and a cover hole, and the body plate 117 has the other of a cover hinge and a cover hole, with the cover hinge inserted into the cover hole. Alternatively, the cover plate 119 and the body plate 117 can be connected by a hinge. Furthermore, it should be noted that this application is not limited to this; in other embodiments, both ends of the cover plate 119 can also be detachably fixed to the body plate 117.

[0064] Please refer to the reference. Figure 2 and Figure 4 In one embodiment of the present invention, the fixed end of the box cover plate 119 is provided with a buckle hole 1191, and the box body 117 is provided with a buckle 1173, which can be engaged or disengaged from the buckle hole 1191.

[0065] It is understood that the combination of the buckle hole 1191 and the snap fastener 1173 has the advantages of simple structure and stable connection. This simplifies the connection structure between the cover plate 119 and the body 117, further reducing manufacturing costs, and also improves the convenience of opening and closing the cover plate 119, while ensuring the stability of the connection between the cover plate 119 and the body 117. Of course, this application is not limited to this. In other embodiments, the fixed end of the cover plate 119 and the body 117 can also be magnetically fixed by interlocking magnets. Furthermore, the surface of the body 117 that abuts against the cover plate 119 can be provided with a sealing element 1175 for the filter installation port 1171 through the sealing element 1175. This reduces the possibility of external airflow flowing into the suction chamber 113 from the gap between the cover plate 119 and the body 117, or the possibility of airflow in the suction chamber 113 flowing out from the gap between the cover plate 119 and the body 117, ensuring the normal and stable operation of the dust collection box 10.

[0066] Please refer to the reference. Figure 7 and Figure 8 In one embodiment of the present invention, the dust collection box 10 further includes a gripping member 15 and a limiting structure 17. The gripping member 15 is rotatably disposed on the box body 11. The limiting structure 17 is connected to the box body 11 and the gripping member 15, and can fix the gripping member 15 when it is rotated to a preset angle limit.

[0067] It is understandable that when the grip 15 is rotated to a preset angle (i.e., placed in place), the limiting structure 17 can limit and fix the grip 15, and increase the rotational force required for the grip 15 to rotate, so that the user can feel the change in rotational force acting on the grip 15. In other words, the limiting structure 17 can provide the user with a prompt that the grip 15 is in place, allowing the user to promptly confirm whether the grip 15 is in place without having to rotate it again for confirmation, thereby improving the convenience of using the dust collection box 10. Alternatively, the limiting structure 17 could emit a prompting sound when the grip 15 is rotated to the preset angle, such as a "click" or "snap" sound. Or, the limiting structure 17 could provide both tactile feedback and audible feedback when the grip 15 is rotated to the preset angle. Furthermore, by limiting and fixing the gripper 15 through the limiting structure 17, the possibility of the gripper 15 shaking can be reduced, thereby improving the stability of the gripper 15 in the placement position. The gripper 15 is rotatably disposed on the box body 117 of the box body 11, and the limiting structure 17 is connected to the box body 117 and the gripper 15.

[0068] Please refer to Figure 8In one embodiment of the present invention, the limiting structure 17 includes a box body protrusion 171 and a gripping protrusion 173. The box body protrusion 171 is disposed on the box body 11; the gripping protrusion 173 is disposed on the gripping member 15. When the gripping member 15 is rotated to a preset angle, the side wall surface of the gripping protrusion 173 abuts against the side wall surface of the box body protrusion 171, so that the gripping member 15 is limited and fixed to the box body 11.

[0069] It is understandable that when the grip 15 is rotated to the preset angle and reaches the placement position, the grip protrusion 173 abuts against one side of the box body 11, and the box body protrusion 171 provides a certain degree of obstruction to the grip protrusion 173. At this time, it is necessary to increase the rotational force applied to the grip 15 until the grip 15 rotates to the placement position, at which point the grip protrusion 173 slides over the surface of the box body protrusion 171 and abuts against the other side of the box body protrusion 171. Thus, the interaction between the box body protrusion 171 and the grip protrusion 173 changes the rotational force required for the grip 15 to rotate, thereby providing the user with a prompt that the grip 1513 is in place. Since the box body protrusion 171 and the grip protrusion 173 protrude from the surfaces of the box body 11 and the grip 15, they are easier to form, reducing the complexity of forming the limiting structure 17, and also increasing the strength of the box body 11 and the grip 15. Of course, it should be noted that this application is not limited to this. In other embodiments, one of the box body 117 of the box 11 and the grip 15 may have a protruding structure, and the other may have a groove structure. When the grip 15 rotates to a preset angle and reaches the placement position, the protruding structure is embedded in the groove structure. Alternatively, the box 11 may have a first magnet, and the grip 15 may have a second magnet. When the grip 15 rotates to a preset angle and reaches the placement position, the second magnet and the first magnet attract and limit each other.

[0070] Please refer to Figure 1 This invention also proposes a robotic vacuum cleaner 100, which includes a dust collection box 10. The specific structure of the dust collection box 10 is as described in the above embodiments. Since the robotic vacuum cleaner 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The robotic vacuum cleaner 100 may also include a housing 30, and the dust collection box 10 may be detachably installed on the upper surface of the housing 30, so that the dust collection box 10 can be directly removed in the direction away from the ground, thereby improving the convenience of removing and placing the dust collection box 10. The connection between the dust collection box 10 and the housing 30 can be by snap-fit ​​fixing or screw connection, etc. This application does not limit the specific method of installing the dust collection box 10 on the housing 30 of the robotic vacuum cleaner 100.
