[0024] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] refer to Figure 1 As shown, an embodiment of this application provides a dust collection box structure 100, which includes a shell 110, a cover 120, a dust collection box body 130, a dust collection pipe 140, and a fan component 150.

[0026] Specifically, in combination Figure 2 and Figure 3 As shown, the housing 110 has a first opening 111, and the cover 120 covers the first opening 111. The cover 120 is movably connected to the housing 110 and defines a receiving cavity 112. The dust collection box body 130 is disposed in the receiving cavity 112. The dust collection box body 130 is provided with a dust collection hole 131 and a filter element 132. The filter element 132 is disposed facing the first opening 111. The output port of the dust collection pipe 140 is disposed corresponding to the dust collection hole 131, so that the dust collection pipe 140 is connected to the dust collection box body 130. The output end of the fan component 150 is connected to the receiving cavity 112. Accordingly, the dust collection box body 130 is installed in the receiving cavity 112 of the housing 110. Under the action of the fan component 150, the fan component... The output end of 150 forms a suction airflow for dust collection. The airflow can communicate with the gas inside the dust collection box body 130 through the filter element 132. The filter element 132 is set facing the first opening 111. Under the action of negative pressure, the dust is sucked into the dust collection box body 130 by the dust collection pipe 140 to ensure the suction effect of the suction airflow. The dust enters the dust collection box body 130 through the output port of the dust collection pipe 140. The dust collection hole 131 is the inlet for dust and impurities to enter the dust collection box body 130. The dust collection box body 130 is used to collect dust and impurities. When it is necessary to clean the dust collection box body 130, the cover 120 is opened and the dust collection box body 130 is taken out through the first opening 111 of the shell 110 to facilitate the maintenance and cleaning of dust and impurities inside the dust collection box body 130, which affects the user experience.

[0027] When vacuuming is required, the fan component 150 generates suction force on the dust collection box body 130 through the filter element 132, causing dust and impurities to be transmitted through the output port of the dust collection pipe 140 to the dust collection hole 131 of the dust collection box body 130, and then the dust and impurities enter the dust collection box body 130. The filter element 132 prevents dust and impurities from entering the fan component 150 and causing blockage of the fan component 150, thus preventing the normal operation of the fan component 150 from being affected.

[0028] For example, the dust collection box body 130 can be assembled and positioned in the receiving cavity 112 of the housing 110. The side wall of the receiving cavity 112 of the housing 110 limits and fixes the dust collection box body 130. At this time, the dust collection hole 131 of the dust collection box body 130 is connected to the dust collection pipe 140 so that dust and debris can be sucked into the dust collection box body 130 through the dust collection pipe 140.

[0029] refer to Figure 1 and Figure 2 As shown, the dust collection box structure 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X refers to the height direction of the dust collection box structure 100, the second direction Y refers to the length direction of the dust collection box structure 100, and the third direction Z refers to the width direction of the dust collection box structure 100. It is understood that the above definitions are only for the purpose of understanding the relative positional relationships of the various parts in the dust collection box structure 100 and should not be construed as limitations on this application.

[0030] It is understandable that, such as Figure 1 As shown, the housing 110 is equipped with a charging port and a dust collection port 141. The robotic vacuum cleaner 200 can be charged and cleaned through the dust collection box structure 100. The charging function and the dust collection box cleaning function of the robotic vacuum cleaner 200 are independent of each other and do not affect each other. When the dust collection box is full, the robotic vacuum cleaner 200 can automatically return to the dust collection box structure 100 to perform a dust collection operation, or when it needs to be charged, it can automatically return to the dust collection box structure 100 to perform a charging operation. The specific functions of the dust collection box structure 100 are not specifically limited here.

[0031] In one embodiment, alternatively, referencing Figure 3 and Figure 4As shown, the dust collection box body 130 includes a box body 133 and a dust collection cover 134. One end of the dust collection cover 134 is hinged to the box body 133, and the other end of the dust collection cover 134 can form a locking structure with the box body 133. The box body 133 serves as a dust collection container responsible for collecting and containing dust and debris. The dust collection cover 134 and the box body 133 form an openable and closable sealed structure. When it is necessary to clean the dust and debris inside the box body 133, the box body 133 can be opened through the dust collection cover 134 to clean the dust and debris. The locking structure prevents the dust collection cover 134 from being opened accidentally. At the same time, the dust collection cover 134 seals the box body 133, reducing the leakage of dust and debris.

[0032] Optionally, such as Figure 4 As shown, the dust collection cover 134 is provided with a first locking member 1341, and the box body 133 is provided with a second locking member 1331 and a second opening 1332. When the dust collection cover 134 is placed over the second opening 1332, the first locking member 1341 and the second locking member 1331 are connected to form the locking structure, or the first locking member 1341 and the second locking member 1331 are separated to open the dust collection cover 134. The locking structure ensures that the dust collection cover 134 forms an airtight seal with the box body 133 after it is closed, preventing dust and debris from leaking out. Moreover, the opening and closing can be completed with one hand, improving the user experience.

[0033] Optionally, refer to Figure 5 As shown, the filter element 132 includes a filter bracket 1322 and a filter screen 1323. The filter screen 1323 is disposed within the filter bracket 1322, and the filter bracket 1322 limits the filter screen 1323. A second handle 1324 is provided on the side of the filter bracket 1322 away from the housing 133. Correspondingly, the filter bracket 1322 has a frame structure, and the filter screen 1323 is disposed within the filter bracket 1322. The filter bracket 1322 supports and fixes the filter screen 1323, ensuring the stability of the filter screen 1323 while allowing for quick disassembly, cleaning, or replacement of the filter screen 1323. The filter bracket 1322 can be removed from the housing 133, and the second handle 1324 facilitates user gripping.

[0034] In summary, the dust collection box body 130 of the dust collection box structure 100 is installed in the receiving cavity 112 of the housing 110. Under the action of the fan component 150, the output end of the fan component 150 forms a suction airflow for dust collection. The airflow can communicate with the gas inside the dust collection box body 130 through the filter element 132. The filter element 132 is set facing the first opening 111. Under the action of negative pressure, dust is sucked into the dust collection box body 130 by the dust collection pipe 140, ensuring the suction effect of the suction airflow. Dust enters the dust collection box body 130 through the output port of the dust collection pipe 140. The dust collection hole 131 is the inlet for dust and impurities to enter the dust collection box body 130. The dust collection box body 130 is used to collect dust and impurities. When it is necessary to clean the dust collection box body 130, the cover 120 is opened and the dust collection box body 130 is taken out through the first opening 111 of the housing 110 to facilitate the maintenance and cleaning of dust and impurities inside the dust collection box body 130, which affects the user experience.

[0035] refer to Figure 1 As shown, an embodiment of this application provides another dust collection box structure 100, which includes a housing 110, a cover 120, a dust collection box body 130, a dust collection pipe 140, and a fan component 150.

[0036] Specifically, in combination Figure 2 and Figure 3 As shown, the housing 110 has a first opening 111, and the cover 120 covers the first opening 111. The cover 120 is movably connected to the housing 110 and defines a receiving cavity 112. The dust collection box body 130 is disposed in the receiving cavity 112. The dust collection box body 130 is provided with a dust collection hole 131 and a filter element 132. The filter element 132 is disposed facing the first opening 111. The dust collection box body 130 is installed in the receiving cavity 112 of the housing 110. Under the action of the fan component 150, the output end of the fan component 150 forms a suction airflow to perform dust collection. The airflow can communicate with the gas inside the dust collection box body 130 through the filter element 132. The filter element 132 is disposed facing the first opening 111. Under the action of negative pressure, the dust is sucked into the dust collection box body 130 by the dust collection pipe 140, ensuring the suction effect of the suction airflow.

[0037] In this embodiment, the output port of the dust collection pipe 140 is configured to correspond to the dust collection hole 131, so that the dust collection pipe 140 is connected to the dust collection box body 130. The output end of the fan component 150 is connected to the receiving cavity 112. Accordingly, dust enters the dust collection box body 130 through the output port of the dust collection pipe 140. The dust collection hole 131 is the inlet for dust and impurities to enter the dust collection box body 130. The dust collection box body 130 is used to collect dust and impurities. When the dust collection box body 130 needs to be cleaned, the cover 120 is opened, and the dust collection box body 130 is taken out through the first opening 111 of the housing 110 to facilitate the maintenance and cleaning of dust and impurities in the dust collection box body 130, which affects the user experience.

[0038] In one embodiment, alternatively, referencing Figure 3 and Figure 4 As shown, the dust collection box body 130 includes a box body 133 and a dust collection cover 134. One end of the dust collection cover 134 is hinged to the box body 133, and the other end of the dust collection cover 134 can form a locking structure with the box body 133. The box body 133 serves as a dust collection container responsible for collecting and containing dust and debris. The dust collection cover 134 and the box body 133 form an openable and closable sealed structure. When it is necessary to clean the dust and debris inside the box body 133, the box body 133 can be opened through the dust collection cover 134 to clean the dust and debris. The locking structure prevents the dust collection cover 134 from being opened accidentally. At the same time, the dust collection cover 134 seals the box body 133, reducing the leakage of dust and debris.

[0039] Optionally, such as Figure 4 As shown, the dust collection cover 134 is provided with a first locking member 1341, and the box body 133 is provided with a second locking member 1331 and a second opening 1332. When the dust collection cover 134 is placed over the second opening 1332, the first locking member 1341 and the second locking member 1331 are connected to form the locking structure, or the first locking member 1341 and the second locking member 1331 are separated to open the dust collection cover 134. The locking structure ensures that the dust collection cover 134 forms an airtight seal with the box body 133 after closing, preventing dust and debris leakage. Furthermore, the opening and closing can be completed with one hand, improving the user experience. For example, the first locking member 1341 is a snap-fit ​​structure with an elastic tongue, and the second locking member 1331 is a recessed groove on the edge of the opening of the box body 133. The two are locked by the engagement of the elastic tongue and the groove.

[0040] Optionally, the dust collection cover 134 is located on one side of the box body 133 relative to the filter element 132, that is, the dust collection cover 134 and the filter element 132 are located on opposite sides of the box body 133. The box body 133 is connected to the outside through the position of the filter element 132, so that the airflow can freely enter and exit the position of the filter element 132 during the suction process of the fan component 150. The filter element 132 plays a blocking role for dust and debris. The dust collection cover 134 can be opened freely to facilitate the cleaning of dust and debris inside the box body 133. For example, the dust collection cover 134 is located at the bottom of the box body 133. When the dust collection cover 134 is opened, the dust and debris inside the box body 133 fall out under the action of gravity, so as to facilitate the cleaning of the box body 133.

[0041] Optionally, refer to Figure 4 As shown, the box body 133 is also provided with a third opening 1333, which faces the first opening 111. The filter element 132 is installed in the third opening 1333. The third opening 1333 of the box body 133 corresponds to the first opening 111 of the housing 110. When the cover 120 is opened through the first opening 111 of the housing 110, the box body 133 in the receiving cavity 112 can be taken out. The filter element 132 is installed at the third opening 1333 of the box body 133. The filter element 132 blocks and filters dust and debris, and at the same time allows airflow to pass through the filter element 132, so that the filter element 132 and the fan element 150 together form an airflow path in the receiving cavity 112.

[0042] For example, the centerline direction of the third opening 1333 is collinear with the centerline direction of the second opening 1332.

[0043] In one embodiment, alternatively, such as Figure 5 As shown, a first limiting step 1334 is provided around the inner wall of the third opening 1333, and a limiting part 1321 is provided circumferentially for the filter element 132. When the filter element 132 is installed in the third opening 1333, the first limiting step 1334 is engaged with the limiting part 1321, and the limiting part 1321 of the filter element 132 is installed on the first limiting step 1334, which improves the installation stability and disassembly convenience of the filter element 132. The filter element 132 can be disassembled from the position of the third opening 1333. The annular design of the limiting step ensures that the filter element 132 is subjected to uniform force in the circumference and prevents local loosening.

[0044] In one embodiment, alternatively, referencing Figure 5As shown, the dust collection box body 130 also includes a first handle 1336. A second limiting step 1335 is defined on the side of the box body 133 near the third opening 1333. The first handle 1336 is hinged to the side of the box body 133 near the third opening 1333, and the first handle 1336 can be at least partially accommodated in the second limiting step 1335. The clearance space formed by the second limiting step 1335 facilitates the placement of the first handle 1336. The first handle 1336 is easy to store when not in use, improving space utilization and avoiding obstruction or influence. The first handle 1336 rotates relative to the box body 133, allowing the user to take the dust collection box body 130 out of the receiving cavity 112 using the first handle 1336. This operation is more convenient and improves the user experience.

[0045] Optionally, refer to Figure 5 As shown, the filter element 132 includes a filter support 1322 and a filter screen 1323. The filter screen 1323 is disposed within the filter support 1322, and the filter support 1322 limits the filter screen 1323. A second handle 1324 is provided on the side of the filter support 1322 away from the housing 133. Correspondingly, the filter support 1322 has a frame structure, and the filter screen 1323 is disposed within the filter support 1322. The filter support 1322 supports and fixes the filter screen 1323, ensuring the stability of the filter screen 1323 while allowing for quick disassembly, cleaning, or replacement of the filter screen 1323. The filter support 1322 can be removed from the housing 133, and the second handle 1324 facilitates user gripping. For example, the filter screen 1323 can be made of HEPA-grade filter media, and the filter support 1322 has a hollow structure, allowing the filter screen 1323 to be snapped into the filter support 1322.

[0046] In one embodiment, alternatively, referencing Figure 1 As shown, the housing 110 is provided with a first transparent portion 113, and the dust collection box body 130 is provided with a second transparent portion. The first transparent portion 113 corresponds to the second transparent portion. The user can directly observe the dust accumulation state inside the second transparent portion through the first transparent portion 113, and can intuitively judge the dust capacity without opening the dust collection box body 130. Furthermore, the dust collection box body 130 is a transparent structure, which allows the dust and debris inside the dust collection box body 130 to be observed through the position of the first transparent portion 113, so as to facilitate cleaning of the dust collection box body 130. For example, both the first transparent portion 113 and the second transparent portion are made of glass material, which has a certain light transmittance, allowing the user to intuitively judge the dust capacity inside the dust collection box body 130.

[0047] like Figure 6 As shown, an embodiment of the present invention also provides a dust collection device, which is applied to a docking robot vacuum cleaner 200.
