Technical Field
[0001] This invention relates to the field of dust collection box technology for robotic vacuum cleaners, and particularly to a dust collection component for robotic vacuum cleaners. Background Technology
[0002] A robotic vacuum cleaner, also known as an automatic cleaning robot, smart vacuum cleaner, or robotic vacuum cleaner, is a type of smart home appliance that uses artificial intelligence to automatically clean floors in a room. It typically uses a combination of brushing and vacuuming to collect debris into its dustbin, thus completing the cleaning process. Generally, robots that perform sweeping, vacuuming, and mopping are all categorized as robotic vacuum cleaners.
[0003] Existing robotic vacuum cleaners have a three-stage cleaning function: dust collection, suction, and dust filtration. A rotating roller brush in the center of the bottom of the machine picks up larger debris and dirt from the floor, while two opposing rotating side brushes on the front left and right sides of the bottom increase the effective cleaning area per pass and sweep dust and debris from corners and under furniture into the dust collection box inside the machine.
[0004] During the operation of a robotic vacuum cleaner, the dustbin can hold different types of dirt. There is usually a filter screen at the junction of the dustbin and the air outlet of the machine. However, if there are large dirt particles collected inside the dustbin, they are easily agitated by the suction airflow generated by the robot and stick to the surface of the filter screen. They are not easy to fall off and can easily cause the filter screen to become clogged. Summary of the Invention
[0005] To address the aforementioned issues, this application provides a dust collection component for a robotic vacuum cleaner.
[0006] To achieve the above objectives, this application provides the following technical solution: a dust collection component for a sweeping robot, including a housing that can be installed inside the cavity of the sweeping robot, a movable baffle is provided on one side of the housing, a dust collection channel is opened on the surface of the movable baffle, which can be connected to the suction port of the sweeping robot, a docking channel is provided on the top of the housing, and a filter element is detachably installed on the inner side of the docking channel.
[0007] The inner cavity of the accommodating box is provided with a guide plate and a gravity transfer plate that can swing back and forth. Some of the dirt in the inner cavity of the accommodating box can slide down the surface of the guide plate and fall onto the gravity transfer plate. The guide plate is set at an angle, and the end of the guide plate faces the side of the gravity transfer plate, forming a channel to accommodate the sliding dirt.
[0008] Furthermore, the guide plate includes a flow guide plate fixed to the wall of the accommodating box. The surface of the flow guide plate is embedded with a mesh plate to block some dust, and larger dirt can slide off the surface of the mesh plate.
[0009] Furthermore, the gravity transfer plate includes a rotatable arc-shaped strip, a rotating sleeve is fixed to the side of the arc-shaped strip, and a detachable alignment structure is provided on the rotating sleeve.
[0010] The bottom end of the arc-shaped strip is fixedly connected to a first silicone plate, the surface of which is provided with a plurality of hemispherical protrusions. The top of the arc-shaped strip is fixedly connected to a second silicone plate. The arc-shaped strip, the first silicone plate and the second silicone plate are distributed in a C-shape in the inner cavity of the accommodating box. The recessed part can bear dirt. The side of the arc-shaped strip is connected to the inner wall of the accommodating box through an elastic structure.
[0011] Furthermore, the elastic structure includes a first docking block that is detachably installed on the surface of the arc-shaped strip and a second docking block that is detachably installed on the wall of the accommodating box. The opposite sides of the first docking block and the second docking block are connected by a compression spring. When the arc-shaped strip, the first silicone plate and the second silicone plate rotate downward, the first docking block moves in an arc and the compression spring is squeezed and contracted.
[0012] Furthermore, the alignment structure includes a central shaft located inside the through hole of the rotating sleeve, and rotatable blocking sleeves are fitted at both ends of the central shaft.
[0013] The surface of the accommodating box is provided with a threaded hole, and a docking knob is detachably installed on the inner side of the threaded hole. When the central shaft and the barrier sleeve are installed on the inner side of the accommodating box, the barrier sleeve and the threaded hole are positioned opposite each other, and the inner hole of the docking knob is threadedly connected to the barrier sleeve.
[0014] Furthermore, an extension rod is fixedly connected to the surface of the docking knob, and the support of the extension rod is located on the outside of the receiving box.
[0015] Furthermore, the filter element includes a frame, a wire mesh filter layer detachably installed on the inner side and lower part of the frame, a guide grille detachably installed on the inner side and upper part of the frame, and a HEPA layer is provided in the interlayer formed by the wire mesh filter layer and the guide grille.
[0016] In summary, the technical effects and advantages of this invention are as follows:
[0017] This invention features a guide plate and a reciprocating gravity transfer plate inside the housing. These components form a channel within the housing's cavity to accommodate falling dirt. Larger impurities can pass through this channel under gravity. The oscillation of the gravity transfer plate further concentrates and transfers larger dirt particles, effectively preventing them from being agitated again by the airflow of the robotic vacuum cleaner. This design effectively limits the amount of dirt inside the housing. Furthermore, it effectively prevents dirt from adhering to the filter, thus avoiding obstruction of airflow. This facilitates the centralized collection of larger dirt particles and promotes the categorized cleaning of dirt within the housing.
[0018] This invention features a detachable gravity transfer plate, which allows for quick and comprehensive cleaning, reducing dirt and grime buildup and ensuring the cleanliness of the gravity transfer plate during long-term use in the vehicle's storage compartment. This facilitates the continuous use of the gravity transfer plate. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0029] Example 1: Reference Figure 1 , Figure 2 and Figure 3 The dust collection assembly of a robotic vacuum cleaner shown includes a housing 1 that can be installed inside the cavity of the robotic vacuum cleaner. A movable baffle 2 is provided on one side of the housing 1, and a dust collection channel is formed on the surface of the movable baffle 2, which can be connected to the suction port of the robotic vacuum cleaner. A docking channel 3 is provided on the top of the housing 1, and a filter 4 is detachably installed on the inner side of the docking channel 3.
[0030] The inner cavity of the container 1 is equipped with a guide plate and a gravity transfer plate that can swing back and forth. Some of the dirt inside the container 1 can slide down the surface of the guide plate and fall onto the gravity transfer plate. The guide plate is set at an angle, with its end facing the side of the gravity transfer plate, forming a channel to accommodate the sliding dirt. Larger impurities can pass through the channel under the action of gravity. As the gravity transfer plate swings, larger dirt can be concentrated and transferred, preventing dirt from adhering to the filter element 4 and obstructing airflow. At the same time, it can collect larger dirt, which is beneficial for the classification and cleaning of dirt inside the container 1.
[0031] like Figure 3 As shown, the guide plate includes a guide plate 5 fixed to the wall of the accommodating box 1. A mesh plate 6 is embedded on the surface of the guide plate 5 to block some dust. Larger dirt particles can slide and fall off the surface of the mesh plate 6. After falling, the dirt enters the inner side of the gravity transfer plate. Since one end of the inclined guide plate faces one side of the gravity transfer plate, the channel formed to accommodate the sliding dirt is curved, which can effectively prevent the dirt from churning under the action of airflow.
[0032] like Figure 3 , Figure 4 and Figure 5 As shown, the gravity transfer plate includes a rotatable arc-shaped strip 7, and a rotating sleeve 14 is fixed to the side of the arc-shaped strip 7. The rotating sleeve 14 is provided with a detachable alignment structure, which can be docked with and disassembled with the accommodating box 1 to achieve the effect of installing and disassembling the entire gravity transfer plate with the accommodating box 1.
[0033] A first silicone plate 8 is fixedly connected to the bottom end of the arc-shaped strip 7. The surface of the first silicone plate 8 is provided with multiple hemispherical protrusions 10. A second silicone plate 9 is fixedly connected to the top of the arc-shaped strip 7. The arc-shaped strip 7, the first silicone plate 8, and the second silicone plate 9 are distributed in a C-shape in the inner cavity of the accommodating box 1. The recessed parts can hold dirt. When larger dirt falls into the recessed parts of the arc-shaped strip 7, the first silicone plate 8, and the second silicone plate 9, most of it accumulates on the surface of the first silicone plate 8 under the action of gravity.
[0034] The protrusions 10 on the surface of the first silicone plate 8 increase the frictional resistance between the first silicone plate 8 and the dirt. The side of the arc-shaped strip 7 is connected to the inner wall of the accommodating box 1 through an elastic structure. The elastic structure can generate pressure deformation, causing the dirt to accumulate. When a certain weight is reached, the arc-shaped strip 7, the first silicone plate 8, and the second silicone plate 9 rotate downwards, transferring the dirt. In the C-shaped structure formed by the connection of the three, the dirt can be effectively prevented from churning again under the action of airflow after passing through the guide plate and gravity transfer plate, thus limiting the dirt inside the accommodating box 1.
[0035] like Figure 3 , such as 4 and Figure 5 As shown, the elastic structure includes a first docking block 11 detachably mounted on the surface of the arc-shaped strip 7 and a second docking block 12 detachably mounted on the wall of the accommodating box 1. The opposite sides of the first docking block 11 and the second docking block 12 are connected by a compression spring 13. When the weight of dirt borne by the arc-shaped strip 7, the first silicone plate 8, and the second silicone plate 9 accumulates and exceeds the supporting force of the compression spring 13, causing the arc-shaped strip 7, the first silicone plate 8, and the second silicone plate 9 to rotate downwards synchronously, the first docking block 11 moves in an arc, and the compression spring 13 is compressed and contracted. This drives the first silicone plate 8 to rotate, and the solid dirt accumulated on its surface quickly falls into the bottom of the inner cavity of the accommodating box 1. Subsequently, the arc-shaped strip 7, the first silicone plate 8, and the second silicone plate 9 return to their original positions.
[0036] As the robot vacuum cleaner works, the arc-shaped strip 7, the first silicone plate 8, and the second silicone plate 9 continuously oscillate, which can separate larger dirt and dust. This can effectively prevent larger dirt from rolling inside the housing 1 due to airflow, causing it to stick to the filter 4. During the disassembly of the housing 1, it is convenient to centrally process the dirt.
[0037] Example 2: Figure 4 , Figure 5 As shown, the alignment structure includes a central shaft 15 located inside the through hole of the rotating sleeve 14. Rotatable blocking sleeves 16 are sleeved at both ends of the central shaft 15. When the central shaft 15 and the blocking sleeves 16 are installed inside the accommodating box 1, the blocking sleeves 16 remain stable.
[0038] The surface of the accommodating box 1 has a threaded hole, and a docking knob 17 is detachably installed inside the threaded hole. When the central shaft 15 and the blocking sleeve 16 are installed inside the accommodating box 1, the blocking sleeve 16 is aligned with the threaded hole, and the inner hole of the docking knob 17 is threadedly connected to the blocking sleeve 16. This maintains the stability of the alignment structure and ensures the stability of the arc-shaped strip 7, the first silicone plate 8, and the second silicone plate 9 when they rotate downwards.
[0039] If it is necessary to disassemble the gravity transfer plate, the docking knob 17 can be rotated to disengage it from the blocking sleeve 16 inside the threaded hole, allowing the central shaft 15 and the blocking sleeve 16 to be easily removed. This has the advantage of convenient disassembly. After disassembling the gravity transfer plate, it can be cleaned quickly and thoroughly, reducing the accumulation of dirt and grime and ensuring the cleanliness of the gravity transfer plate during long-term use in the vehicle-mounted housing 1, which is conducive to the continuous use of the gravity transfer plate.
[0040] like Figure 4 , Figure 5 As shown, an extension rod 18 is fixedly connected to the surface of the docking knob 17, and the support feet of the extension rod 18 are located on the outside of the housing 1. The purpose of providing the extension rod 18 is to facilitate the control of the rotation of the docking knob 17, so as to adjust the position of the docking knob 17 and smoothly dock with and disassemble the barrier sleeve 16, which has the advantage of portable operation.
[0041] like Figure 2 , Figure 7 As shown, the filter element 4 includes a frame 41, a wire mesh filter layer 42 detachably installed on the inner side and lower part of the frame 41, and a guide grille 44 detachably installed on the inner side and upper part of the frame 41. A HEPA layer 43 is disposed within the interlayer formed by the wire mesh filter layer 42 and the guide grille 44. During the operation of the housing 1, the filter element 4 is usually connected to the air outlet of the robot vacuum cleaner. The purpose of the filter element 4 is to prevent dust in the air from being discharged again through the air outlet, thus purifying the air.
[0042] The HEPA layer 43 has a high molecular fiber structure, which can improve the filtration accuracy. By combining the wire mesh filter layer 42, the HEPA layer 43 and the guide grid 44 on the inner side of the frame 41, it has the advantages of combining coarse filtration and fine filtration, and can effectively avoid clogging of the filter element 4.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
