Description

Technical Field

[0002] As people's living standards improve, mobile robots such as floor scrubbers and sweeping robots have become common equipment in homes and commercial spaces. These mobile robots are usually equipped with dust collection boxes.

[0003] Currently, after the mobile robot finishes vacuuming, it will drive into the base station to remove the dust, so that the garbage in the dust collection box can be discharged into the dust collection box of the base station. However, the dust removal effect is often not good, and a lot of garbage remains in the dust collection box. This will cause the suction power of the mobile robot to drop significantly, which will easily affect the vacuuming ability of the mobile robot and cause high load to damage the motor. At the same time, it is easy to breed bacteria and odor. Summary of the Invention

[0031] The technical solutions provided in this disclosure have at least the following advantages: In the dust removal mode, the first door of the disclosed dust collection box opens the airflow inlet under the action of external airflow, and the second door opens the dust removal outlet under the action of external airflow. This allows the external airflow to enter through the airflow inlet and first pass through the horizontal guide section at the bottom for buffering and initial guidance. Then, the external airflow encounters the inclined guide section. Since the top surface of the inclined guide section is an upwardly inclined inward surface, the horizontal airflow energy is converted into an upward lifting force and a forward blowing force when it encounters the inward inclined surface. This allows the dust and debris in the box to flow easily along the inward inclined surface to the dust removal outlet and be discharged from the box through the dust removal outlet. This effectively eliminates the dead airflow corner at the bottom, allowing dust and debris to be discharged smoothly and avoiding the accumulation of dust and debris in the box. This improves the dust removal and cleaning effect of the dust collection box, thereby ensuring the suction power of the intelligent robot and the service life of the motor. At the same time, it can also reduce the growth of bacteria and odors in the dust collection box and improve the user experience.

[0044] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art.

[0045] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0046] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0047] This disclosure provides a dust collection box that can be applied to intelligent robots with dust collection functions, such as floor scrubbers and sweepers. However, it is not limited to this. The dust collection box of this embodiment can also be applied to immovable devices with dust collection functions, depending on the specific circumstances.

[0048] The structure of the dust collection box according to the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.

[0049] In some embodiments, combined with Figure 1 and Figure 2 As shown, the dust collection box 10 may include a box body 101, a first door 102, and a second door 103. The inner cavity of the box body 101 is used to store dust, garbage, and other debris. The box body 101 has an airflow inlet 1011 and a dust outlet 1012, which are arranged sequentially in the dust discharge direction. The first door 102 is located at the airflow inlet 1011 and is used to open or close the airflow inlet 1011. The second door 103 is located at the dust outlet 1012 and is used to open or close the dust outlet 1012.

[0050] Specifically, in combination Figure 3 As shown, in dust removal mode, that is, when it is necessary to discharge dust and debris from the inner cavity of the dust collection box 10, the first door 102 needs to open the airflow inlet 1011, and the second door 103 needs to open the dust discharge outlet 1012. In non-dust removal mode, refer to... Figure 2 As shown, the first door 102 can close the airflow inlet 1011, and the second door 103 can close the dust outlet 1012. For example, when the dust collection box 10 is used in an intelligent robot, if the intelligent robot is in cleaning mode, the first door 102 closes the airflow inlet 1011 and the second door 103 closes the dust outlet 1012 in cleaning mode to prevent dust and garbage from flowing back or leaking out from the airflow inlet 1011 and the dust outlet 1012, thereby ensuring the normal dust collection performance of the cleaning equipment during daily cleaning.

[0051] It should be understood that when the dust collection box 10 is in a non-working state, that is, when the dust collection box 10 is neither in dust discharge mode nor in cleaning mode, the first door 102 can close the airflow inlet 1011 and the second door 103 can close the dust discharge outlet 1012.

[0052] In some embodiments, reference Figure 2 As shown, a dust inlet 1013 may be provided on the side wall of the box 101, and the dust inlet 1013 may be connected to the inner cavity of the box 101. The dust inlet 1013 is located between the airflow inlet 1011 and the dust outlet 1012, and the extension direction of the dust inlet 1013 intersects the dust outlet direction. It should be noted that the extension direction of the dust inlet 1013 is the direction that penetrates through the side wall of the box 101.

[0053] In this embodiment, reference Figure 2 As shown, when the side wall of the box 101 has a dust inlet 1013, the dust collection box 10 can be used in an intelligent robot. Specifically, it can be installed in the main unit 20 of the intelligent robot. It should be understood that the area of ​​the main unit 20 corresponding to the dust inlet 1013 can also be provided with an opening (not shown in the figure). In cleaning mode, under the action of the first fan 30 in the intelligent robot, external dust and garbage can be sucked into the inner cavity of the box 101 through the opening and the dust inlet 1013.

[0054] For example, continue to refer to Figure 2 As shown, the inner cavity of the housing 101 is also provided with a filter assembly 104, which divides the cavity of the housing 101 into an upper cavity 101a and a lower cavity 101b. The airflow inlet 1011, dust outlet 1012, and dust inlet 1013 are all connected to the lower cavity 101b, which can be understood as a dust storage cavity for storing dust and debris; the upper cavity 101a can be understood as a filter cavity, wherein, reference Figure 2 As shown, the upper cavity 101a is provided with an air outlet 1014, which can be used to connect to the first fan 30 in the intelligent robot.

[0055] Specifically, when the intelligent robot is in cleaning mode, the first fan 30 in the intelligent robot is started, and the airflow is discharged through the dust inlet 1013, the filter assembly 104 and the air outlet 1014 to suck in external dust or garbage and filter it using the filter assembly 104 to separate it and store it in the dust storage chamber of the dust storage box 10.

[0056] In some embodiments, reference Figure 2 As shown, the bottom wall of the box 101 includes a horizontal guide section 1015a and an inclined guide section 1015b, wherein the airflow inlet 1011, the horizontal guide section 1015a, the inclined guide section 1015b and the dust outlet 1012 are arranged sequentially along the dust discharge direction.

[0057] refer to Figure 3 As shown, the top and bottom surfaces of the horizontal guide section 1015a extend horizontally, while at least the top surface of the inclined guide section 1015b is an inwardly inclined surface 10151. Figure 3 and Figure 4As shown, the end of the inner inclined surface 10151 that is away from the horizontal guide section 1015a is inclined upward, that is, the top surface of the inclined guide section 1015b extends obliquely upward.

[0058] In this embodiment, combined with Figure 3 and Figure 4 As shown, when the dust collection box 10 is in dust discharge mode, the first door 102 opens the airflow inlet 1011 under the action of external airflow, and the second door 103 opens the dust discharge outlet 1012 under the action of external airflow. This allows the external airflow to enter through the airflow inlet 1011 and first pass through the horizontal guide section 1015a at the bottom for buffering and initial guidance. Then, the external airflow encounters the inclined guide section 1015b. Since the top surface of the inclined guide section 1015b is an upwardly inclined inner inclined surface 10151, the horizontal airflow energy is blocked when it encounters the inner inclined surface 10151. The inclined surface 10151 is converted into an upward lifting force and a forward blowing force, which allows the dust and debris inside the box 101 to flow easily along the inner inclined surface 10151 to the dust outlet 1012 and be discharged from the box 101 through the dust outlet 1012. This effectively eliminates the dead airflow corner at the bottom, allowing dust and debris to be discharged smoothly and avoiding the accumulation of dust and debris inside the box 101. This improves the dust removal and cleaning effect of the dust collection box 10, thereby ensuring the suction power of the intelligent robot and the service life of the motor. At the same time, it can also reduce the growth of bacteria and odors inside the dust collection box 10, and improve the user experience.

[0059] It should be noted that, Figure 3 The bold black arrows indicate the direction of airflow.

[0060] In some embodiments, the bottom surface of the inclined guide section 1015b can be a plane and flush with the bottom surface of the horizontal guide section 1015a. This design results in the thickness of the inclined guide section 1015b gradually increasing in the dust discharge direction. This structure not only effectively ensures the structural strength and reliability of the bottom wall of the dust collection box 10, but also ensures the flatness of the outer bottom surface of the dust collection box 10, thereby facilitating the stable placement of the dust collection box 10.

[0061] In some embodiments, reference Figure 4 As shown, the bottom surface of the inclined guide section 1015b is the outer inclined surface 10152, which is parallel or approximately parallel to the inner inclined surface 10151.

[0062] In order to ensure the structural strength and stable support of the bottom wall of the box 101, when the bottom surface of the inclined guide section 1015b is an outer inclined surface 10152 that is parallel or approximately parallel to the inner inclined surface 10151, reference is made. Figure 4As shown, a support column 105 is provided at the end of the outward inclined surface 10152 away from the horizontal guide section 1015a, and the bottom surface of the support column 105 is flush with the bottom surface of the horizontal guide section 1015a.

[0063] In some embodiments, the inclination angle of the inner inclined surface 10151 can be from 0.3° to 5°, such as 0.3°, 0.6°, 1.2°, 1.6°, 2.6°, 5°, etc. By ensuring that the inclination angle of the inner inclined surface 10151 is not less than 0.3°, the dust removal efficiency is improved and smooth dust removal is ensured. By ensuring that the inclination angle of the inner inclined surface 10151 does not exceed 5°, the situation where the structural stability of the box 101 is weak due to excessive inclination angle is avoided, that is, the structural stability of the box 101 is ensured.

[0064] In some embodiments, the dimension of the horizontal guide section 1015a in the dust discharge direction is A, and the dimension of the inclined guide section 1015b in the dust discharge direction is B; wherein, B ÷ (A + B) = D, and D is 15% to 60%, such as 15%, 18%, 36%, 43%, 58%, 60%, etc. By designing this ratio to be no less than 15%, the airflow can be guaranteed to accelerate smoothly and climb the slope smoothly. By designing this ratio to be no more than 60%, the overall height of the machine can be effectively controlled and the mold forming difficulty can be reduced, thus achieving a balance between dust discharge performance and spatial layout.

[0065] In some embodiments, combined with Figure 2 and Figure 5 As shown, the airflow inlet 1011 can be opened at the bottom of the side wall of the box 101, which can prevent dust or garbage in the inner cavity of the box 101 from falling or blocking the airflow inlet 1011 under the action of gravity.

[0066] For example, the first door 102 may also be provided at the bottom of the side wall of the box 101 so as to open or close the airflow inlet 1011 accordingly.

[0067] In some embodiments, the first door 102 can be installed in the inner cavity of the box 101. By hiding the first door 102 in the inner cavity of the box 101, the first door 102 is effectively prevented from being directly exposed to the external environment, thereby reducing the risk of collision damage and improving the overall aesthetics and structural protection of the product.

[0068] In some embodiments, reference Figure 5As shown, the first door 102 may include a mounting portion 1021, a cover portion 1022, and a recess 1023. The mounting portion 1021 is mounted on the housing 101 so that the entire first door 102 is mounted on the housing 101; the cover portion 1022 covers the airflow inlet 1011; the recess 1023 connects the mounting portion 1021 and the cover portion 1022, and the thickness of the recess 1023 is less than the thickness of the mounting portion 1021 and the cover portion 1022; wherein, the cover portion 1022 is configured to bend along the recess 1023 in dust exhaust mode to open the airflow inlet 1011.

[0069] In this embodiment, by using the thinner recess 1023 as the connection between the cover 1022 and the mounting part 1021, a flexible bending area is formed by reducing the thickness of the connection. This allows the first door 102 to bend smoothly along the recess 1023 to open the airflow inlet 1011 when dust is discharged. This effectively reduces structural stress and wear while realizing the opening and closing function of the first door 102.

[0070] For example, see reference Figure 5 As shown, the thickness of the mounting part 1021 can be greater than the thickness of the cover part 1022. By increasing the thickness of the mounting part 1021, the structural strength and connection reliability of the fixed end of the first door body 102 are improved, while keeping the cover part 1022 thin and light, so as to facilitate smooth bending and opening and closing.

[0071] In some embodiments, the first door body 102 can be an integral structure, which effectively avoids gaps caused by splicing multiple parts and significantly improves the sealing reliability and assembly efficiency of the structure.

[0072] The first door 102 can be integrally molded from soft rubber material. The soft rubber material gives the first door 102 elastic deformation capability, allowing the first door 102 to bend and open smoothly.

[0073] In some embodiments, reference Figure 5 As shown, an installation wall 1010 protruding from the side wall of the box 101 can be formed on the top side of the airflow inlet 1011. The installation wall 1010 is located in the inner cavity of the box 101. The top end of the first door 102 is connected to the installation wall 1010, and the bottom end of the first door 102 abuts against the bottom wall of the box 101 to close the airflow inlet 1011.

[0074] When the first door body 102 includes the aforementioned mounting portion 1021, recess 1023, and cover portion 1022, refer to Figure 5 As shown, the mounting part 1021 is located at the top of the mounting wall 1010 and is connected to the mounting wall 1010, and the recess 1023 abuts against the side end of the mounting wall 1010.

[0075] In this embodiment, the protruding mounting wall 1010 provides stable support and limit for the first door 102, and the side end of the mounting wall 1010 abuts against the recess 1023 of the first door 102 to achieve precise bending guidance.

[0076] In some embodiments, reference Figure 5 As shown, the bottom end of the cover portion 1022 may form an abutment portion 1024 protruding towards the airflow inlet 1011, and the bottom side of the airflow inlet 1011 is formed with a rib 1016 protruding relative to the top surface of the bottom wall of the box body 101; wherein, the abutment portion 1024 is configured to abut against the rib 1016 to close the airflow inlet 1011.

[0077] In this embodiment, the protruding abutment portion 1024 and the rib 1016 are precisely matched, which greatly improves the sealing performance and air leakage prevention effect when the airflow inlet 1011 is closed, and at the same time effectively enhances the structural support strength of the first door 102 in the closed state.

[0078] In some embodiments, reference Figure 5 As shown, the bottom wall of the box 101 also includes a horizontal extension section 1015c. The horizontal extension section 1015c is located on the side of the horizontal guide section 1015a away from the inclined guide section 1015b, and extends toward the side wall where the airflow inlet 1011 is provided. The extension end face of the horizontal extension section 1015c is flush with the outer surface of the side wall of the box 101.

[0079] In this embodiment, by setting the horizontal extension section 1015c, the support area of ​​the box 101 can be guaranteed, thus ensuring the stable placement of the box 101.

[0080] For example, see reference Figure 5 As shown, the orthographic projection of the mounting wall 1010 onto the bottom wall of the housing 101 can be located within the horizontal extension 1015c. Furthermore, the ribs 1016 can be provided in the region of the horizontal extension 1015c near the horizontal guide section 1015a.

[0081] In some embodiments, reference Figure 6 and Figure 7 As shown, a first alignment opening 1017a is formed in the area corresponding to the bottom wall of the housing 101 and the mounting wall 1010. The first alignment opening 1017a is located on the outside of the first door 102, and can be used to achieve alignment with the main unit 20. For example, when the dust collection box 10 is installed inside the main unit 20, the first alignment opening 1017a can be aligned with the air duct opening 201 on the bottom wall of the main unit 20.

[0082] It should be noted that the reference Figure 1 and Figure 2As shown, the host unit 20 can be the host of the intelligent robot. Besides the dust collection box 10, the host unit 20 can also house a first fan 30 and a control box (not shown in the figure), etc. Further reference is needed. Figure 1 and Figure 2 As shown, when the intelligent robot is a mobile robot, the bottom of the main unit 20 may also be equipped with walking wheels 40, etc.; when the intelligent robot is a cleaning robot, and the cleaning robot includes the aforementioned structures, the main unit 20 may also be equipped with a water tank 50, and the bottom of the main unit 20 may also be equipped with walking wheels 40, mopping components 60, sweeping components 70, etc., which will not be described in detail here.

[0083] In this embodiment, by reserving a first alignment port 1017a on the dust collection box 10, the dust collection box 10 is precisely connected to other structures, thereby greatly simplifying the assembly process of the dust collection box 10 and effectively ensuring the sealing and reliability of the air duct connection.

[0084] For example, see reference Figure 6 and Figure 7 As shown, a first protrusion 106 is formed on the side of the first alignment port 1017a near the first door body 102. The bottom surface of the first protrusion 106 protrudes relative to the bottom surface of the horizontal guide section 1015a. When the dust collection box 10 is installed in the main unit 20, the first protrusion 106 is positioned in the air duct port 201 on the bottom wall of the main unit 20.

[0085] In this embodiment, the first protrusion 106 is precisely inserted and matched with the air duct opening 201 of the host 20, which realizes the reliable positioning of the dust collection box 10 and greatly improves the sealing performance of the air duct connection.

[0086] In some embodiments, reference Figure 2 As shown, the inner cavity of the box 101 is provided with a mounting plate 107 to divide the inner cavity of the box 101 into a main cavity Q1 and a dust discharge cavity Q2. The mounting plate 107 has a dust discharge port 1012, which penetrates the mounting plate 107 in the thickness direction and also penetrates the bottom end of the mounting plate 107. The bottom end of the dust discharge cavity Q2 is an open second alignment port 1017b.

[0087] For example, see reference Figure 2 and Figure 4 As shown, the top of the second door 103 is hinged to the mounting plate 107, and the bottom of the second door 103 abuts against the side of the second alignment port 1017b near the inclined guide section 1015b to close the dust discharge port 1012; wherein, the bottom of the second door 103 is configured to move away from the inclined guide section 1015b in the dust discharge mode to open the dust discharge port 1012, so that the main cavity Q1 is connected to the second alignment port 1017b.

[0088] Among them, reference Figures 2 to 4 As shown, the second alignment port 1017b can be aligned with the main unit 20. For example, when the dust collection box 10 is installed inside the main unit 20, the second alignment port 1017b can be aligned with the dust collection and recovery port 202 on the bottom wall of the main unit 20.

[0089] In this embodiment, by reserving a second alignment port 1017b on the dust collection box 10, precise docking of the dust collection box 10 with other structures is achieved, thereby greatly simplifying the assembly process of the dust collection box 10 and effectively ensuring the sealing and reliability of the dust discharge connection. In addition, by designing the mounting plate 107, the cavity of the box body 101 can be reasonably divided, and the hinge linkage mechanism of the second door 103 is used to realize the automatic opening and closing of the dust discharge channel, effectively ensuring smooth dust discharge and cavity sealing.

[0090] It should be noted that the reference Figure 2 As shown, the main cavity Q1 mentioned here may be equipped with the aforementioned filter assembly 104 to divide the main cavity Q1 into the aforementioned upper cavity 101a and lower cavity 101b.

[0091] For example, an elastic reset member (not shown in the figure) may also be provided between the top of the second door 103 and the mounting plate 107. When the airflow in the box 101 is insufficient to push the second door 103, under the action of the elastic reset member, the bottom of the second door 103 falls back to the side of the inclined guide section 1015b and abuts against the second alignment port 1017b, thereby achieving reliable sealing of the dust discharge port 1012 again.

[0092] In some embodiments, reference Figure 2 and Figure 4 As shown, the second door 103 may include a first baffle 1031 and a second baffle 1032. The top end of the first baffle 1031 is connected to the mounting plate 107, and the top end of the second baffle 1032 is connected to the bottom end of the first baffle 1031. The bottom end of the second baffle 1032 abuts against the side of the second alignment port 1017b near the inclined guide section 1015b to close the dust discharge port 1012. The included angle between the first baffle 1031 and the second baffle 1032 is an obtuse angle, so that the second baffle 1032 can form a diffuser to prevent garbage blockage.

[0093] In this embodiment, combined with Figure 2 and Figure 3As shown, the airflow enters the inner cavity of the box 101 through the airflow inlet 1011, and flows at high speed towards the dust discharge port 1012 along the horizontal guide section 1015a and the inclined guide section 1015b. At this time, this airflow will generate an outward aerodynamic force on the second door 103, namely, wind pressure thrust. When the wind pressure thrust is greater than the weight of the second door 103 itself and the possible spring restoring force, the bottom of the second door 103 will be blown open by the airflow and move away from the inclined guide section 1015b, thereby opening the dust discharge port 1012. At this time, since the first baffle 1031 and the second baffle 1032 form an obtuse angle, the second baffle 1032 will form a diffuser that aligns with the dust collection and recovery port 202. This diffuser effectively prevents the garbage from accumulating and getting stuck when it falls and is discharged, thereby greatly improving the smoothness of dust discharge and effectively preventing the dust discharge port 1012 from getting blocked.

[0094] It should be understood that when the airflow thrust that drives the second door 103 to open disappears, the bottom of the second door 103 falls back to the side of the inclined guide section 1015b under its own weight (or the return spring) and abuts against the second alignment port 1017b, thus reliably sealing the dust discharge port 1012 again.

[0095] For example, see reference Figure 4 As shown, the top of the second baffle 1032 is inclined away from the inclined guide section 1015b when the second door 103 closes the dust discharge port 1012. This design makes the second baffle 1032 form an outwardly inclined windward slope when closed, which can effectively guide the airflow to smoothly guide the garbage downward, and also provide aerodynamic lift for the second door 103 to open outward under the impact of the airflow, thereby reducing dust discharge resistance and improving the anti-clogging effect.

[0096] In some embodiments, the dust outlet 1012 is not limited to being located inside the housing 101, but may also be located on the side wall of the housing 101, see reference. Figure 8 As shown, a dust discharge port 1012 is opened on the side wall of the box 101. The second door 103 has a first end and a second end. The first end is hinged to the box 101 by a pivot, and the second end can move away from the inclined guide section 1015b to open the dust discharge port 1012. The axis of the pivot is in the thickness direction of the dust collection box 10. This allows the second door 103 to open smoothly by tilting to the side. This not only effectively avoids interference with the internal garbage falling channel when the second door 103 is opened and closed, but also further improves the smoothness of dust discharge and the compactness of the overall structure.

[0097] In some embodiments, reference Figure 4As shown, the bottom wall of the box body 101 also includes an abutment section 1015d, which is located near the inclined guide section 1015b on the side away from the horizontal guide section 1015a. The top surface of the abutment section 1015d is in contact with the inner inclined surface 10151 on the side near the inclined guide section 1015b, and the top surface of the abutment section 1015d is inclined downward on the side away from the inclined guide section 1015b. The bottom end of the second door body 103 is at least in contact with the top surface of the abutment section 1015d.

[0098] In this embodiment, by setting an abutment section 1015d with a specific tilt angle, a precise positioning support is provided for the second door 103. This not only ensures the sealing reliability of the second door 103 when it is closed, but its downward tilted top surface can also effectively guide the garbage to slide smoothly to the dust collection and recycling inlet 202, preventing garbage accumulation and jamming at the bottom of the second door 103.

[0099] The top surface of the abutting section 1015d can be a downward-sloping plane, meaning that the angle of inclination is consistent at all points on the top surface. However, it is not limited to this. The top surface of the abutting section 1015d can include multiple inclined sections with different angles of inclination, so that the top surface of the abutting section 1015d is inclined downward as a whole.

[0100] For example, see reference Figure 4 As shown, the bottom end of the second door 103 can also abut against the side of the abutment section 1015d (the surface that forms the second alignment opening 1017b), ensuring a double seal when the second door 103 is closed.

[0101] It should be noted that the surface of the second door body 103 that abuts against the abutting section 1015d can be defined as the abutting surface 1033, which can fit against the top surface of the abutting section 1015d.

[0102] In some embodiments, reference Figure 9 As shown, the bottom end of the abutment surface 1033 is inclined away from the inclined guide section 1015b, and the angle formed between the abutment surface 1033 and the inner inclined surface 10151 is an obtuse angle; however, it is not limited to this, the abutment surface 1033 can also be a vertical surface pointing downwards. In this case, the top surface of the abutment section 1015d forms a right-angled stepped surface, and the abutment surface 1033 can fit against the vertical surface of the right-angled stepped surface; or, refer to Figure 11 As shown, the bottom end of the contact surface 1033 is inclined toward the inclined guide section 1015b, and the top surface of the contact section 1015d is formed with an acute-angled step surface. The contact surface 1033 is in contact with the inclined surface of the acute-angled step surface near the inclined guide section 1015b.

[0103] For example, see reference Figure 2 and Figure 4As shown, a second protrusion 108 is provided at the end of the bottom surface of the abutment section 1015d away from the inclined guide section 1015b. The bottom surface of the second protrusion 108 can be flush with the bottom surface of the horizontal guide section 1015a to ensure the structural strength and stable support of the bottom wall of the box body 101.

[0104] In some embodiments, the bottom surface of the second protrusion 108 may also protrude relative to the bottom surface of the horizontal guide section 1015a. When the dust collection box 10 is installed inside the host 20, the second protrusion 108 is positioned inside the dust collection and recovery port 202 on the bottom wall of the host 20. By precisely inserting and cooperating the protruding second protrusion 108 with the dust collection and recovery port 202 of the host 20, the reliable positioning of the dust collection box 10 is achieved, and the sealing performance at the joint of the dust collection and recovery port 202 is greatly improved.

[0105] In some embodiments, the bottom surfaces of the first protrusion 106 and the second protrusion 108 may be flush with each other to ensure stable support of the dust collection box 10.

[0106] This disclosure also provides an intelligent robot, combined with Figure 1 and Figure 2 As shown, the system includes a main unit 20 and a dust collection box 10, which may be located inside the main unit 20. It should be noted that the dust collection box 10 here may be the structure described in any of the foregoing embodiments. The specific structure of the dust collection box 10 will not be repeated here. The specific structure of the dust collection box 10 mentioned later can be directly used in the corresponding scenario.

[0107] In some embodiments, reference Figure 2 As shown, the bottom wall of the host 20 is provided with an air duct 201 and a dust collection and recovery port 202. In the airflow path of the dust removal mode: the air duct 201 is located upstream of the airflow inlet 1011, and the dust collection and recovery port 202 is located downstream of the dust discharge port 1012. That is to say, in the dust removal mode, when the external fan (such as the second fan in the base station) is started, the airflow flows through the air duct 201, the airflow inlet 1011, the dust discharge port 1012 and the dust collection and recovery port 202 in sequence.

[0108] In some embodiments, reference Figure 2As shown, the air duct opening 201 can be located on the side of the airflow inlet 1011 away from the dust outlet 1012. In order to make the airflow at the air duct opening 201 flow towards the airflow inlet 1011, the intelligent robot in this embodiment also includes an air duct cover 80. The air duct cover 80 can be located inside the main unit 20. The air duct cover 80 includes a cover body 801 and a cover side wall 802. The cover body 801 covers the air duct opening 201. The cover side wall 802 is formed on the side of the cover body 801 near the airflow inlet 1011. The cover body 801, the cover side wall 802 and the bottom wall of the main unit 20 form a guide channel. The cover side wall 802 is provided with an air passage structure 8021 that communicates with the interior of the guide channel.

[0109] For example, combined Figure 8 As shown, the cover body 801 includes an arc-shaped wall 8011 and a horizontal wall 8012. The orthographic projection of the arc-shaped wall 8011 on the bottom wall of the host 20 is at least partially located at the air duct opening 201. One end of the horizontal wall 8012 is connected to the top of the arc-shaped wall 8011, and the other end is connected to the cover side wall 802.

[0110] In this embodiment, the smooth transition between the arc-shaped wall 8011 and the horizontal wall 8012 can effectively guide the airflow to reduce flow resistance and eddies, thereby improving dust removal efficiency. At the same time, it makes the structure of the duct cover 80 more compact and the transition smoother.

[0111] For example, the air passage structure 8021 can be an air passage grille. Using an air passage grille as the air passage structure 8021 can effectively rectify and reduce noise, reduce wind resistance and block foreign objects, thereby improving the smoothness of dust exhaust airflow and the operational reliability of the equipment.

[0112] In some embodiments, the intelligent robot includes Figure 2 The first fan 30 shown can be connected to the air outlet 1014. When the intelligent robot needs to vacuum, the first fan 30 is started, and the airflow is discharged through the dust inlet 1013, the filter assembly 104, and the air outlet 1014 to suck in external dust or garbage and filter it using the filter assembly 104 for separation and storage.

[0113] For example, see reference Figure 2 As shown, the top of the cover sidewall 802 can extend to the air outlet 1014, and the first fan 30 can be located on the side of the cover sidewall 802 away from the air outlet 1014. Multiple through holes 8022 are provided in the area of ​​the cover sidewall 802 opposite to the air outlet 1014.

[0114] In this embodiment, the first fan 30 can be evenly connected to the air outlet 1014 through multiple through holes 8022 on the side wall 802 of the cover, which effectively reduces local wind resistance and balances the airflow distribution, thereby improving the dust collection efficiency and exhaust smoothness of the intelligent robot.

[0115] It should be noted that the specific structure of the intelligent robot in this embodiment can be referred to the content described above, and will not be repeated here.

[0116] In some embodiments, reference Figure 7 As shown, when the dust collection box 10 has a first alignment port 1017a, when the dust collection box 10 is installed inside the host 20, the orthographic projection of the first alignment port 1017a on the bottom wall of the host 20 is located inside the air duct port 201. This can shorten the airflow path and make the structure of the dust collection box 10 more compact.

[0117] In some embodiments, reference Figure 3 As shown, when the dust collection box 10 has a second alignment port 1017b, when the dust collection box 10 is installed inside the main unit 20, the orthogonal projection of the second alignment port 1017b on the bottom wall of the main unit 20 covers the dust collection and recovery port 202; wherein, when the second door 103 opens the dust discharge port 1012, the bottom end of the second door 103 is located inside the dust collection and recovery port 202 and abuts against the side of the dust collection and recovery port 202 away from the inclined guide section 1015b, so as to avoid dust or garbage accumulating on the bottom wall of the main unit 20 and ensure the emptying effect.

[0118] In some embodiments, reference Figure 3 As shown, the dust collection and recovery inlet 202 can be located on the side of the dust discharge port 1012 away from the airflow inlet 1011. This design conforms to the movement direction of the dust discharge airflow, enabling the dust collection and recovery inlet 202 to accurately receive and suck up the garbage passing through the dust discharge port 1012, thereby effectively preventing material retention and accumulation, and greatly improving the smoothness of dust discharge and recycling efficiency.

[0119] In some embodiments, reference Figure 8 As shown, when the second door 103 opens the dust discharge port 1012 by flipping it to the side, the intelligent robot also includes a guide plate 21. The guide plate 21 is installed inside the host 20, and the orthographic projection of the guide plate 21 on the bottom wall of the host 20 is located inside the dust collection and recycling port 202. The bottom surface of the guide plate 21 is a guide slope. The side of the guide slope away from the dust discharge port 1012 is inclined downward and higher than the second door 103. That is to say, the guide slope is higher than the second door 103 as a whole.

[0120] In this embodiment, after the second door 103 tilts to open the dust outlet 1012, the airflow can be guided to the guide slope by the inclined guide section 1015b. The guide slope guides the airflow downward, meaning that at least some dust or debris will fall down after hitting the guide slope. Since the dust collection and recovery outlet 202 is located below the guide slope, the guide slope can accurately guide the dust or debris into the dust collection and recovery outlet 202. In addition, by setting the guide slope higher than the second door 103, interference between the guide plate 21 and the second door 103 can be avoided when the second door 103 tilts, ensuring the smooth opening of the second door 103.

[0121] For example, see reference Figure 8 As shown, the intelligent robot also includes a support plate 22, which is installed inside the main unit 20 and located on the side of the dust collection and recycling port 202 away from the inclined guide section. The bottom end of the support plate 22 is supported on the bottom wall of the main unit 20, and the top end of the support plate 22 can be connected to the bottom end of the guide plate 21, so that the guide plate 21 is installed inside the main unit 20.

[0122] The support plate 22 can be installed perpendicular to the bottom wall of the host 20, but it is not limited to this. The top of the support plate 22 can also be tilted towards the inclined guide section. The orthogonal projection of the top of the support plate 22 on the bottom wall of the host 20 can be located in the dust collection and recovery port 202 to further guide the dust and garbage coming out of the dust discharge port 1012.

[0123] For example, the connection between the support plate 22 and the guide plate 21 can be curved to ensure structural strength.

[0124] This disclosure also provides an intelligent system, which may include a base station and an intelligent robot. The structure of the intelligent robot can be referred to the foregoing content and will not be repeated here.

[0125] In some embodiments, reference Figure 12 As shown, the base station may include a base 90, a dust collection box 91, and a second fan 92. The base 90 has an installation cavity and a docking cavity. The dust collection box 91 and the second fan 92 are installed in the installation cavity. The intelligent robot is configured to enter and exit the docking cavity. After the intelligent robot enters the docking cavity, the air duct 201 is connected to the second fan 92 through the circulating air path 93, and the dust collection recovery port 202 is connected to the dust collection box 91 through the dust collection recovery pipeline 94.

[0126] In this embodiment, after the intelligent robot completes its cleaning task and enters the docking chamber of the base station, two independent air paths working in tandem are formed inside the base station. On one hand, the base station's second fan 92 starts, connecting to the intelligent robot's air duct 201 via the circulating air path 93, generating a directional suction negative pressure inside the intelligent robot. On the other hand, the dust collection and recovery pipeline 94 connects the intelligent robot's dust collection and recovery port 202 to the base station's dust collection box 91. Under the powerful suction of the negative pressure generated by the second fan 92, the garbage and dust collected in the dust storage box 10 inside the intelligent robot are forcefully sucked in and transferred along the dust collection and recovery pipeline 94, and centrally stored in the base station's dust collection box 91, thereby achieving automatic emptying and recycling of garbage. It should be noted that the base station is not limited to including the base 90, dust collection box 91, and second fan 92; it may also include a cleaning mechanism or a charging mechanism to clean or charge the intelligent robot, which will not be described in detail here.
