[0018] In some embodiments, the first and second sensors are distributed along the direction of movement of the moving part.

[0030] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. The application will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0031] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0032] In this application, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this application.
[0033] This application provides a dust collection box assembly, which is detachably disposed within a cleaning device for collecting dirt (dust, hair, etc.) generated during the cleaning process. In one application scenario, the cleaning device is a robotic vacuum cleaner, and the dust collection box assembly is the dustbin assembly of the robotic vacuum cleaner. Of course, the cleaning device includes, but is not limited to, robotic vacuum cleaners; it can also be other cleaning devices with dirt collection modules, such as mite removers, pool robots, and air purifiers. Furthermore, the dust collection box assembly is not limited to cleaning devices and can also be used in other devices with airflow filtration. The following description uses the application of the dust collection box assembly in a robotic vacuum cleaner as an example, but as can be seen from the above description, the scope of protection of this application is not limited thereto.
[0034] like Figures 1 to 4 As shown, the dust collection box assembly includes a dust box 100, which has space inside for installing a filter unit 200. The dust box 100 is also provided with an air inlet 111 and an air outlet 112. External dirty airflow enters the dust box 100 through the air inlet 111, is filtered by the filter unit 200, and is discharged through the air outlet 112, thereby achieving the purpose of filtering the airflow.
[0035] The dust box 100 has a dirty chamber 101 and a clean chamber 102, which are connected by a filter unit 200. The dirty chamber 101 collects dirt filtered by the filter unit 200. The clean chamber 102 provides flow space for the filtered airflow within the dust box 100. An air inlet 111 communicates with the dirty chamber 101 and is located on the chamber wall of the dirty chamber 101. An air outlet 112 communicates with the clean chamber 102 and is located on the chamber wall of the clean chamber 102.
[0036] The function of filter unit 200 is to filter airflow. Filter unit 200 has a dense, multi-layered fiber structure that traps hair and large debris within the dustbin 100, ensuring relatively clean air exiting the dustbin 100. This prevents dirt in the airflow from being directly sucked into the robot vacuum's fan (not shown), which could affect its normal operation. Filter unit 400 needs to be replaced approximately every two months under normal use. For users with pets, due to the larger amount of pet debris (hair), the replacement interval for filter unit 400 will be more frequent. Filter unit 400 is detachable and mounted on the dustbin 100, allowing users to replace it periodically.
[0037] To prevent users from forgetting to reinstall the dustbin 100 back into the robot vacuum after cleaning it, or from forgetting to install the new filter unit 200 onto the dustbin 100 after replacing the old filter unit 200, the dustbin assembly in this application further includes a movable member 300, which is slidably disposed within the dustbin 100 and cooperates with the filter unit 200.
[0038] Specifically, the movable component 300 has a first position when the filter unit 200 is removed from the dust box 100, and a second position when the filter unit 200 is installed in the dust box 100. The movable component 300 switches between the first position and the second position in response to the removal and installation of the filter unit 200. (See attached image) Figure 4 This is a schematic diagram showing the movable part 300 in the first position; attached. Figure 3 This is a schematic diagram of the movable part 300 in the second position.
[0039] In the second position, the movable part 300 abuts (collides) with the filter unit 200, achieving linkage through the abutting cooperation, resulting in a simpler structure and more reliable movement. Furthermore, the abutting cooperation between the movable part 300 and the filter unit 200 also limits the movement of the filter unit 200. When airflow passes through the filter unit 200, the filter unit 200 tends to sway due to the airflow. If the filter unit 200 sways, gaps will be created, allowing dirty airflow to bypass the filter unit 200 and directly enter the fan, which is undesirable. The abutting of the movable part 300 with the filter unit 200 constrains the filter unit 200, preventing it from swaying.
[0040] The movable component 300 is equipped with a sensing element 310, which is used to cooperate with the sensors on the robotic vacuum cleaner. In one embodiment, the sensing element 310 is a component capable of generating or changing a magnetic field, and the sensor is a Hall sensor. The sensing element 310 can be an energized wire, coil, electromagnet, or magnet (permanent magnet), etc. Preferably, the sensing element 310 is a magnet.
[0041] When the movable part 300 moves, it causes the sensing element 310 to move along with it. The movable part 300 changes the position of the sensing element 310, giving it both a first position and a second position. The sensing state is controlled by changing the relative position of the sensing element 310 (magnet) and the Hall sensor. When the sensing element 310 is within the sensing range of the Hall sensor, the sensor outputs one state; when the sensing element 310 is outside the sensing range of the Hall sensor, the sensor outputs another state.
[0042] Regarding the location of the movable component 300, the movable component 300 is located within the clean chamber 102; alternatively, the movable component 300 is distributed independently of the clean chamber 102 and the dirty chamber 101. The dirty chamber 101 contains dirt. If the movable component 300 is located within the dirty chamber 101, the dirt within the dirty chamber 101 will affect the reliability of the movable component 300's movement. Therefore, it is best to avoid installing the movable component 300 within the dirty chamber 101. When the movable component 300 is located in an independent chamber, it is possible to effectively prevent interference and influence from the external environment on the movable component 300 and the sensing element 310.
[0043] like Figure 5 As shown, a mounting groove 305 is recessed in the movable part 300, and the sensing element 310 is disposed within the mounting groove. For example, the sensing element 310 can be disposed within the mounting groove 305 by means of adhesive bonding or interference fit. The groove wall of the mounting groove 305 can withstand external forces from all directions. Even if the adhesive fails, the sensing element 310 is still confined within the mounting groove 305 by the groove wall and will not shift, achieving precise positioning. During installation, workers or robotic arms can easily place the sensing element 310 into the mounting groove 305, resulting in good installation and positioning performance.
[0044] The sensing element 310 is positioned close to the wall of the dustbin 100 to facilitate its interaction with the Hall sensor on the robot vacuum. Since magnetic field strength decreases sharply with increasing distance, mounting the sensing element 310 close to the wall of the dustbin 100 minimizes the distance between the sensing element 310 and the external Hall sensor, thereby ensuring the reliability and stability of the sensing.
[0045] In this application, the movable part 300 is floatingly disposed within the dust box 100 via a biasing member 320. The biasing member 320 is a compression spring or a spring. One end of the biasing member 320 is connected to the movable part 300, and the other end is connected to the inner wall of the dust box 100.
[0046] The dust box 100 has a first chamber 103 for housing the filter unit 200, which can be understood as the space occupied by the filter unit 200. In a first position, the movable member 300 extends at least partially into the first chamber 103, and in a second position, the movable member 300 retracts from the first chamber 103.
[0047] The dustbin 100 also includes a second chamber 104 communicating with the first chamber 103, with the movable component 300 partially located within the second chamber 104. The sensing component 310 and the biasing component 320 are located within the second chamber 104. The first chamber 103 and the second chamber 104 are adjacent to each other, with the second chamber 104 positioned closer to the wall of the dustbin 100, resulting in a more compact overall structure. This also minimizes the distance between the sensing component 310 and the external Hall sensor, thereby ensuring the reliability and stability of the sensing.
[0048] The second chamber 104 is a closed cavity. This closed cavity reduces the influence of the external environment on the moving part 300, the sensing element 310, and the biasing element 320, making the movement of the moving part 300 and the biasing element 320 more stable and reliable. Figure 4 As shown, the second chamber 104 has an opening, and a cover plate 140 is detachably provided on the opening of the second chamber 104, making the second chamber 104 a closed chamber. The cover plate 140 can be connected by buckles, fasteners, etc.
[0049] A third chamber 105 is provided between the first chamber 103 and the second chamber 104, and the third chamber 105 communicates with both the first chamber 103 and the second chamber 104. The third chamber 105 is configured to accommodate the portion of the movable member 300 located outside the second chamber 104 when it is in the second position. A partition 106 is provided between the third chamber 105 and the second chamber 104. The movable member 300 has a stepped portion 330 that mates with the partition 106. The stepped portion 330 and the partition 106 are configured to limit the retraction limit position of the movable member 300. When the stepped portion 330 abuts against the partition 106, the movable member 300 cannot retract further and is at its retraction limit position.
[0050] like Figure 6As shown, a pair of ribs 106 are provided, symmetrically distributed. A gap 107 exists between the pair of ribs 106, forming a passageway for the movable member 300, allowing part of the movable member 300 to extend into the first chamber 103 and part to reside within the second chamber 104. As can be seen from the above, the third chamber 105 and the ribs 106 can limit the movement of the movable member 300, making its movement more stable and reliable.
[0051] like Figure 5 As shown, the movable component 300 includes a first rod portion 301 acting on the filter unit 200, a second rod portion 302 connected to the first rod portion 301, and a third rod portion 303 connected to the second rod portion 302. The first rod portion 301 has an abutment block 304 at its end away from the second rod portion 302, which abuts against the filter unit 200. The second rod portion 302 has a mounting groove 305 at its end away from the second rod portion 302.
[0052] The first rod portion 301 and the third rod portion 303 are located on the same side of the second rod portion 302. Furthermore, the first rod portion 301 and the third rod portion 303 are distributed in parallel. Even further, the first rod portion 301 and the third rod portion 303 are both perpendicular to the second rod portion 302, and the first rod portion 301, the second rod portion 302, and the third rod portion 303 are rigidly connected, forming a compact structure and a stable whole.
[0053] When the first rod 301 and the third rod 303 are located on the same side of the second rod 302, the sensing element 310 and the abutment block 304 are also located on the same side of the second rod 302. Conversely, if the sensing element 310 and the abutment block 304 are not on the same side, but are located on opposite sides of the second rod 302, then the size of the moving part 300 (length and / or width) will inevitably increase. The moving part 300 occupies a large space, resulting in a larger overall size of the dust collection box assembly, which ultimately affects the size of the robot vacuum cleaner, which is undesirable.
[0054] In one embodiment, one end of the biasing member 320 is connected to the movable member 300, and the other end is connected to the cavity wall of the second chamber 104. Specifically, as shown... Figure 3 and Figure 6 As shown, the third rod portion 303 is L-shaped, with one end of the biasing member 320 abutting against the short side of the third rod portion 303, where the sensing member 310 is also located on the aforementioned short side. A support block 108 is provided on the cavity wall of the second chamber 104, distributed opposite to and located behind the aforementioned short side. One end of the biasing member 320 abuts against the short side of the third rod portion 303, and the other end abuts against the support block 108.
[0055] Therefore, when the filter unit 200 is installed in the first chamber 103, the filter unit 200 pushes the movable member 300 to move backward, and the biasing member 320 is pressed between the short side of the third rod portion 303 and the support block 108. At this time, the biasing member 320 is under pressure. When the filter unit 200 is removed from the first chamber 103, the movable member 300 moves forward under the action of the elastic force of the biasing member 320.
[0056] A stop block 304 is disposed on a connecting plate 306 and connected to the end of the first rod portion 301 via the connecting plate 306. The projection of the connecting plate 306 in the sliding direction of the movable member 300 is larger than the projections of the stop block 304 and the first rod portion 301 in the sliding direction. The area of the connecting plate 306 is larger than the area of the end of the first rod portion 301. The stop block 304 is mounted on the connecting plate 306, which has a larger area, resulting in more stable, reliable, and convenient installation. Due to the difference in cross-sectional size between the connecting plate 306 and the end of the first rod portion 301, the aforementioned stepped portion 330 is formed for limiting the movement of the movable member 300.
[0057] like Figure 1 and Figure 4 As shown, the dustbin 100 includes a box body 110, a bracket 120 disposed at the opening of the box body 110, and a box cover 130 that can be opened and closed at the opening of the bracket 120. The opening of the box body 110 is located at the top of the box body 110, and the bracket 120 is located at the top of the box body 110. The opening of the bracket 120 is located at the top of the bracket 120, and the box cover 130 is located at the top of the bracket 120.
[0058] The filter unit 200 is housed within the bracket 120, such as Figure 9 As shown, the inner wall of the cover 130 is provided with raised ribs 131 distributed along the edge of the filter unit 200. The raised ribs 131 are configured to press against the filter unit 200 in the closing direction when the cover 130 is closed on the bracket 120. As a result, the filter unit 200 is confined within the bracket 120, and the filter unit 200 will not shake when airflow passes through it.
[0059] In this application, the rib 131 and the first chamber 103 can limit the position of the filter unit 200 in the vertical direction. For example... Figure 2 and Figure 8 , 6As shown, the bottom of the first chamber 103 is stepped, which restricts the movement and rotational freedom of the filter unit 200 in the front, back, left, right, and down directions. The protruding rib 131 is located above the filter unit 200, restricting its upward movement. The movable member 300 can press the filter unit 200 into the first chamber 103. As can be seen from the above, the protruding rib 131, the first chamber 103, and the movable member 300 can limit the filter unit 200 in different directions, resulting in good limiting effect.
[0060] like Figure 7 As shown, the filter unit 200 is a HEPA filter. The filter unit 200 includes at least filter paper 210 and a mounting frame 220 surrounding the filter paper 210. The mounting frame 220 has a flow port 223 for airflow, located in the vertical direction. The filter paper 210 is installed on the mounting frame 220 by applying adhesive around its periphery and then fixing it to the mounting frame 220. The filter unit 200 interacts with the movable component 300 through the mounting frame 220.
[0061] The mounting bracket 220 includes a bracket body 221 and a filter paper cover 222. The bottom of the bracket body 221 is open, and the filter paper cover 222 is located at the bottom opening of the bracket body 221. The bracket body 221 and the filter paper cover 222 enclose a space for receiving the filter paper 210. Both the bracket body 221 and the filter paper cover 222 are provided with the aforementioned flow ports 223, which are distributed on the top and bottom surfaces of the mounting bracket 220, allowing airflow to flow from bottom to top.
[0062] When the filter unit 200 is installed in the first chamber 103, such as Figure 3 As shown, the sidewall of the mounting bracket 220 abuts against the movable part 300. The sidewall of the mounting bracket 220 refers to the surface between its top and bottom surfaces. The mounting bracket 220 is made of rigid plastic to ensure the abutment effect of the movable part 300. For example, the mounting bracket 220 can be made of ABS material, which has high strength, good toughness, and is not easily deformed. This ensures the accuracy of the first and second positions of the movable part 300, avoiding floating first and second positions that would affect the sensing accuracy of the Hall sensor.
[0063] Furthermore, such as Figure 7 and Figure 8 As shown, the filter unit 200 also includes a sealing ring 230, which is used to seal the gap between the filter unit 200 and the wall of the first chamber 103, so that the airflow in the dirty chamber 101 can only enter the clean chamber 102 after being filtered by the filter unit 200, thus preventing unfiltered dirty airflow from directly entering the clean chamber 102 through the gap and eventually entering the fan.
[0064] The sealing ring 230 is located on the bottom end face of the filter unit 200, such as... Figure 8 As shown, the bottom of the first chamber 103 has a communication port 1031, and the sealing ring 230 is located on the outer periphery of the communication port 1031. Of course, the sealing ring 230 can also be located inside the first chamber 103, and the user can choose the installation position of the sealing ring 230 according to the actual situation.
[0065] Please continue reading. Figure 2 and Figure 8 The bottom opening of the support body 221 has a stepped inner wall, which is used to limit the filter paper cover 222. A sealing ring 230 is located below the filter paper cover 222, with part of the sealing ring 230 situated within the space formed by the stepped inner wall and part extending outside the space. The bottom end face 2211 of the support body 221 does not contact the bottom end face 1033 of the first chamber 103. The vertical distance between the bottom end face 2211 of the support body 221 and the bottom end face 1033 of the first chamber 103 is equal to the height of the portion of the sealing ring 230 extending to the outside of the support body 221. This provides both a good sealing effect and shock absorption. When the cover 130 is placed on the support 120, the rib 131 presses down on the filter unit 200, causing the sealing ring 230 at the bottom of the filter unit 200 to fit tightly against the bottom end face 1033 of the first chamber 103.
[0066] Compared to existing dustbin structures, the filter unit 200 in this application eliminates the magnet, instead placing the magnet on the sliding movable part 300. This way, when replacing the filter unit 200, the magnet is not replaced along with the filter unit, resulting in lower replacement costs for users and a greater market advantage. The filter unit 200 only includes a mounting bracket 220, filter paper 210, and a sealing ring 230, further reducing replacement costs for users and enhancing its market appeal.
[0067] Furthermore, such as Figure 2 and Figure 9 As shown, a sealing strip 160 is provided on the bottom end face of the lid 130 or at the top opening of the first chamber 103. The sealing strip 160 extends along the opening of the first chamber 103 and is annular. In one embodiment, the sealing strip 160 is provided on the bottom end face of the lid 130, and an annular groove 161 that mates with the sealing strip 160 is provided on the bottom end face of the lid 130. The sealing strip 160 is located in the annular groove 161. The rib 131 is located inside the annular groove 161.
[0068] In this application, as Figure 9The dustbin 100 is pivotally connected to the bracket 120 via one edge 132, and at least one of the remaining edges of the dustbin 130 engages with the bracket 120. In one embodiment, the pivoting structure and the engaging structure 230 on the dustbin 130 are located on a pair of opposing edges. The pivoting structure provides a stable base for rotation, while the engaging structure 230 ensures the locking force of the dustbin 130 in the closed state. Together, they prevent the dustbin 100 from being easily opened by airflow during use.
[0069] The lid 130 is provided with a snap-fit structure 150. Specifically, a notch is provided along one edge of the lid 130, and the snap-fit structure 150 is located within the notch. The snap-fit structure 150 includes a U-shaped arm 151 located within the notch, and one arm of the U-shaped arm 151 is provided with a protruding ridge 152, such as... Figure 6 As shown, the wall of the bracket 120 has a notch 121 that mates with the protrusion 152. The U-shaped arm 151 has its opening facing upwards. One end of the U-shaped arm 151 is connected to the lid 130, and the other end is free. A gripping block 153 is also provided on the free end of the U-shaped arm 151, located directly above the protrusion 152. When the locking structure 150 engages with the notch 121, the gripping block 153 is positioned above the bracket 120. This allows the user to use the gripping block 153 to move one side of the U-shaped arm 151 closer to the other side wall of the U-shaped arm 151, thereby disengaging the protrusion 152 from the notch 121 and releasing the locking relationship between the lid 130 and the bracket 120.
[0070] Furthermore, the inner wall of the bracket 120 is provided with a groove 122 that mates with the U-shaped arm 151. The groove 122 is located directly below the recess of the cover 130 and is used to accommodate the U-shaped arm 151 and provide physical protection for the U-shaped arm 151. The groove 122 is independent of the first chamber 103.
[0071] When the protruding rib 152 engages with the opening 121, the force between the protruding rib 152 and the opening 121 can effectively press the sealing strip 160 against the opening of the first chamber 103, thus achieving a good sealing effect.
[0072] like Figures 10 to 14 As shown, this application also provides a cleaning device, which includes a main body 600, a dust collection box assembly detachably disposed on the main body 600, and a filter unit 200 detachably disposed within the dust collection box assembly. The main body 600 has a groove 610, and the dust collection box assembly is detachably disposed within the groove 610, wherein the dust collection box assembly is the dust collection box assembly described above.
[0073] In one scenario, the aforementioned cleaning device is a robotic vacuum cleaner. Of course, cleaning devices include, but are not limited to, robotic vacuum cleaners; they can also be other devices with dustbin components, such as vacuum cleaners with ironing functions, filtration devices, etc. The following explanation uses a robotic vacuum cleaner as an example, but as can be seen from the above description, the scope of protection of this application is not limited thereto.
[0074] To detect whether the dustbin 100 has been reinstalled on the main body 600 after disassembly and cleaning, and to detect whether the filter unit 200 has been reinstalled in the dustbin 100, a first sensor 510 and a second sensor 520 are provided on the main body 600. The first sensor 510 and the second sensor 520 are distributed along the movement direction (front-back direction) of the movable part 300. By detecting the above two situations through the first sensor 510 and the second sensor 520, the robot vacuum cleaner can be prevented from malfunctioning due to the user forgetting to install the dustbin 100 and the filter unit 200.
[0075] In one embodiment, a Hall effect sensor 620 is mounted on the main body 600. The Hall effect sensor 620 is equipped with a first sensor 510 and a second sensor 520. The Hall effect sensor 620 is connected to a PCB board (not shown) on the main body 600. The Hall effect sensor 620 is located outside the groove 610 and close to the outer wall of the groove 610.
[0076] In this application, the sensing element 310 cooperates with the first sensor 510 and the second sensor 520 to realize the presence detection of the dust box 100 and the filter unit 200. The sensing element 310 changes the distance between itself and the first sensor 510 and the second sensor 520 through the sliding movement of the movable element 300, thereby realizing the presence detection of the dust box 100 and the filter unit 200. That is to say, by cooperating between one sensing element 310 and two sensors (the first sensor 510 and the second sensor 520), the presence detection of the dust box 100 and the filter unit 200 can be realized, reducing the number of components and lowering production costs.
[0077] When the dust collection box assembly is installed inside the main body 600 but the filter unit 200 is not installed inside the dust collection box assembly, the sensor 310 is within the sensing range of one of the first sensor 510 and the second sensor 520, but outside the sensing range of the other. One of the first sensor 510 and the second sensor 520 emits a sensing signal, while the other does not. At this time, it indicates that the dust collection box assembly is installed correctly but the filter unit 200 is not, and the cleaning equipment can remind you to install the filter unit 200.
[0078] When the dust collection box assembly is installed inside the main body 600 and the filter unit 200 is installed inside the dust collection box assembly, the sensing element 310 is within the sensing range of both the first sensor 510 and the second sensor 520. At this time, both the first sensor 510 and the second sensor 520 can simultaneously sense the sensing element 310. Both the first sensor 510 and the second sensor 520 emit sensing signals, indicating that the dust collection box assembly and the filter unit 200 are installed in place, and the cleaning equipment can perform subsequent cleaning work normally.
[0079] Specifically, when the dust collection box assembly is installed inside the main body 600 and the filter unit 200 is not installed inside the dust collection box assembly, one of the first sensor 510 and the second sensor 520 is located between the sensing element 310 and the other of the first sensor 510 and the second sensor 520. The sensing element 310, the first sensor 510, and the second sensor 520 are located at the three vertices of an obtuse triangle, with the sensing element 310 located on the longest side of the obtuse triangle.
[0080] When the dust collection box assembly is installed inside the main body 600 and the filter unit 200 is installed inside the dust collection box assembly, the sensing element 310 is located between the first sensor 510 and the second sensor 520, and the sensing element 310, the first sensor 510, and the second sensor 520 are located at the three vertices of an acute triangle.
[0081] The positional relationships between the moving part 300, the sensing part 310, the first sensor 510, and the second sensor 520 have been described in detail above. Those skilled in the art should understand the following in-situ detection process.
[0082] In one embodiment, when the dustbin 100 is mounted on the main body 600 and the filter unit 200 is installed inside the dustbin 100, such as Figure 10 As shown, the sensing element 310 is positioned between the first sensor 510 and the second sensor 520. At this position, the detection range thresholds d1 and d2 of the first sensor 510 and the second sensor 520 are controlled to be: d1 > a and d2 > b. Both the first sensor 510 and the second sensor 520 emit sensing signals. Wherein, d1 is the detection range threshold of the first sensor 510; d2 is the detection range threshold of the second sensor 520; a is the length of the line connecting the first sensor 510 and the sensing element 310 when the movable element 300 is in the second position; and b is the length of the line connecting the second sensor 520 and the sensing element 310 when the movable element 300 is in the second position.
[0083] When the dustbin 100 is installed on the main body 600 but the filter unit 200 is not installed inside the dustbin 100, such as Figure 11As shown, under the action of the bias member 320, the sensing member 310 moves forward to the position shown in the attached figure. At this time, the detection range threshold d1 of the first sensor 510 is controlled at: d1 > f, and the detection range threshold d2 of the second sensor 520 is controlled at: d2 < h. The first sensor 510 emits a sensing signal, and the second sensor 520 does not sense it. Wherein, d1 is the detection range threshold of the first sensor 510; d2 is the detection range threshold of the second sensor 520; f is the length of the line connecting the first sensor 510 and the sensing member 310 when the movable member 300 is in the first position; and h is the length of the line connecting the second sensor 520 and the sensing member 310 when the movable member 300 is in the first position.
[0084] In another embodiment, when the dust collection box assembly is installed within the main body 600 and the filter unit 200 is not installed within the dust collection box assembly, the sensing element 310 is located within the sensing range of one of the first sensor 510 and the second sensor 520, and outside the sensing range of the other. If one of the first sensor 510 and the second sensor 520 emits a sensing signal, while the other does not, it indicates that the dust collection box assembly is installed correctly but the filter unit 200 is not, and the cleaning equipment can remind the user to install the filter unit 200.
[0085] When the dust collection box assembly is installed inside the main body 600 and the filter unit 200 is installed inside the dust collection box assembly, the sensing element 310 is located within the sensing range of one of the first sensor 510 and the second sensor 520, and outside the sensing range of the other. Specifically, if one of the first sensor 510 and the second sensor 520 emits a sensing signal, and the other does not emit a sensing signal, it indicates that the dust collection box assembly and the filter unit 200 are properly installed, and the cleaning equipment can perform subsequent cleaning work normally.
[0086] Specifically, such as Figure 15As shown, when the dustbin 100 is installed on the main body 600 but the filter unit 200 is not installed in the dustbin 100, the sensor 310 is in the first position. The sensor 310 is within the sensing range of the first sensor 510 but not within the sensing range of the second sensor 520. At this time, the detection range threshold d1 of the first sensor 510 is controlled at: d1 > z1, and the detection range threshold d2 of the second sensor 520 is controlled at: d2 < z2. The sensor 310 is within the sensing range of the first sensor 510 but not within the sensing range of the second sensor 520. At this time, the first sensor 510 sends a sensing signal, indicating that the dustbin 100 is in place but the filter unit 200 is not in place. Wherein, d1 is the detection range threshold of the first sensor 510; d2 is the detection range threshold of the second sensor 520; z1 is the length of the line connecting the first sensor 510 and the sensing element 310 when the movable member 300 is in the first position; and z2 is the length of the line connecting the second sensor 520 and the sensing element 310 when the movable member 300 is in the first position.
[0087] like Figure 16 As shown, when the dust box 100 is installed on the main body 600 and the filter unit 200 is installed inside the dust box 100, the sensing element 310 is in the second position. The sensing element 310 is not within the sensing range of the first sensor 510, but within the sensing range of the second sensor 520. The detection range threshold d1 of the first sensor 510 is controlled at: d1 < z3, and the detection range threshold d2 of the second sensor 520 is controlled at: d2 > z4. The sensing element 310 is not within the sensing range of the first sensor 510, but within the sensing range of the second sensor 520. At this time, the second sensor 520 sends a sensing signal, indicating that the dust box 100 and the filter unit 200 are both installed in place. Wherein, d1 is the detection range threshold of the first sensor 510; d2 is the detection range threshold of the second sensor 520; z3 is the length of the line connecting the first sensor 510 and the sensing element 310 when the movable member 300 is in the second position; and z4 is the length of the line connecting the second sensor 520 and the sensing element 310 when the movable member 300 is in the second position.
[0088] When the dust box 100 is not installed on the main body 600, neither the first sensor 510 nor the second sensor 520 can detect the sensing element 310.
[0089] The robot vacuum cleaner can also be equipped with a voice alarm module or a buzzer to remind the user, so that the user can realize that the dust box 100 and filter unit 200 have not been installed into the main body 600 through voice reminders.
[0090] like Figure 12 , Figure 13 and Figure 17As shown, this application also provides a cleaning device, which includes: a main body 600, a dust collection box assembly detachably disposed on the main body 600, and a filter unit 200 detachably disposed within the dust collection box assembly. The main body 600 has a groove 610, and the dust collection box assembly is detachably disposed within the groove 610. The dust collection box assembly is the same as described above, and will not be elaborated further here.
[0091] In one scenario, the aforementioned cleaning device is a robotic vacuum cleaner. Of course, cleaning devices include, but are not limited to, robotic vacuum cleaners; they can also be other devices with dustbin components, such as vacuum cleaners with ironing functions, filtration devices, etc. The following explanation uses a robotic vacuum cleaner as an example, but as can be seen from the above description, the scope of protection of this application is not limited thereto.
[0092] like Figure 18 and Figure 19 As shown, the main body 600 is also equipped with a sensor 500 that cooperates with the sensing element 310. The sensor 500 is configured to sense the sensing element 310 when the movable element 300 is in the first position or the second position. The sensing element 310 is a magnet, and the sensor 500 is a Hall sensor.
[0093] When the dust collection box assembly is not installed on the main body 600, or when the dust collection box assembly is installed on the main body 600 but the filter unit 200 is not installed on the dust collection box assembly, the sensing element 310 is outside the sensing range of the sensor 500. In this case, the sensor 500 does not emit a sensing signal, indicating that the dust collection box assembly and / or filter unit 200 are not properly installed, and the cleaning equipment can remind you to install the dust collection box assembly and / or filter unit 200.
[0094] When the dust collection box assembly is installed inside the main body 600 and the filter unit 200 is installed inside the dust collection box assembly, the sensing element 310 is within the sensing range of the sensor 500. At this time, it means that the dust collection box assembly and the filter unit 200 are both installed in place, and the cleaning equipment can perform cleaning tasks normally.
[0095] When the dust collection box assembly is installed inside the main body 600 and the filter unit 200 is installed inside the dust collection box assembly, the movable part 300 abuts against the filter unit 200, which can limit the filter unit 200.
[0096] Specifically, such as Figure 18As shown, when the moving part 300 is in the first position, the filter unit 200 is not installed in the dustbin 100, and the sensing element 310 is outside the sensing range of the sensor 500. The detection range threshold d3 of the sensor 500 is controlled at: d3 < c, the sensor 500 does not sense the sensing element 310, and the robot vacuum cleaner can remind the user that the filter unit 200 has not been installed in the dustbin 100 and cannot perform the cleaning task. Here, d3 is the detection range threshold of the sensor 500; c is the length of the line connecting the sensing element 310 and the sensor 500 when the moving part 300 is in the first position.
[0097] like Figure 19 As shown, when the movable part 300 is in the second position, the filter unit 200 is installed inside the dustbin 100, and the sensing element 310 is within the sensing range of the sensor 500. The detection range threshold d3 of the sensor 500 is controlled such that d3 > r. When the sensor 500 senses the sensing element 310, the robot vacuum cleaner can remind the user that the filter unit 200 has been installed inside the dustbin 100 and can perform cleaning operations normally. Here, d3 is the detection range threshold of the sensor 500; r is the length of the line connecting the sensing element 310 and the sensor 500 when the movable part 300 is in the second position.
[0098] In this embodiment, a sensing element 310 and a sensor 500 are provided, which can realize the presence detection of the filter unit 200, effectively preventing the user from forgetting to install the new filter unit 200 back onto the main body 600 during the replacement of the filter unit 200. The configuration of one sensing element 310 and one sensor 500 effectively reduces the number of components, simplifies the installation process, and reduces manufacturing costs.
[0099] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the scope of protection of this application.
