DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] like Figures 1 to 5 As shown, a dust collection device of a sweeping robot includes a dust collection box 100, a dust collection pipe 200, a junction tube 300, a mounting sleeve 400 and a connecting sleeve 500.

[0027] like Figures 1 to 5 As shown, a dust collection device of a sweeping robot is mounted on a housing 600 of the sweeping robot. The sweeping robot is provided with at least two side brushes 700, and each side brush 700 has a cleaning surface formed at the end thereof for cleaning. The dust collection device includes:

[0028] A dust box 100 is provided on the housing 600;

[0029] The dust collection assembly includes a dust collection tube 200 and a dust collection connector. One end of the dust collection tube 200 is connected to the dust collection box 100, and the other end extends to and connects to the dust collection connector. The dust collection connector is detachably mounted on the housing 600 and located between the two side brushes 700. The dust collection connector has a confluence portion 310 that is adapted to the height of the cleaning surface and extends in the direction of the two side brushes 700. The inner diameter of the confluence portion 310 gradually decreases from the outside to the inside. When the two side brushes 700 rotate, the dust collection assembly can suck debris removed by the side brushes 700 into the dust collection box 100 through the dust collection connector. This design enables a single dust collection connector, under the action of the confluence portion 310, to absorb debris removed by multiple side brushes 700. This expands the dust collection coverage of the dust collection assembly while ensuring its simplicity and compactness, and effectively reduces the manufacturing cost of the dust collection device.

[0030] Specifically, if Figures 1 to 5 As shown, in this embodiment, the sweeping robot includes a housing 600, and at least two side brushes 700 are provided below the housing 600. Each side brush 700 is composed of a plurality of bristles dispersed in a ring shape, and a cleaning surface for cleaning is formed at the end of each side brush 700. Preferably, the side brush 700 includes a first side brush 710 and a second side brush 720 arranged side by side.

[0031] In this embodiment, the dust suction device includes a dust box 100 arranged above the housing 600, and a dust suction component connected to the dust box 100. The dust box 100 is mainly used to collect debris and dust, and is provided with a power source for driving the dust suction device to work. The dust suction component is mainly used to form a dust suction channel between the side brush 700 and the dust box 100 to ensure that the debris cleaned by the side brush 700 can be smoothly sucked into the dust box 100.

[0032] In this embodiment, the dust collection assembly includes a dust collection tube 200 and a dust collection connector. One end of the dust collection tube 200 is connected to the dust collection box 100, and the other end extends away from the dust collection box 100 and extends through the housing 600 to the dust collection connector. The design of the dust collection tube 200 allows the dust collection connector to be placed in a specific position as needed, thereby reducing the restrictions on the installation position of the side brush 700 and effectively increasing the flexibility of the side brush 700 placement.

[0033] In this embodiment, the dust suction tube 200 is a hollow flexible tube that can be bent, stretched or compressed as needed, so that the dust suction tube 200 can adapt to different installation positions and angles. While improving the installation flexibility of the dust suction component, it also makes the disassembly and assembly of the dust suction connector more convenient.

[0034] In this embodiment, the diameter of the dust collection tube 200 gradually decreases along its length, with the diameter of the dust collection tube 200 near the dust collection connector being larger than the diameter of the end near the dust collection box 100. This diameter difference provides greater suction to the dust collection connector, enabling it to effectively absorb debris removed by the side brush 700. The gradually decreasing diameter also allows for smoother air flow, reduces air resistance, and improves dust collection efficiency.

[0035] To achieve the simultaneous absorption of debris cleaned by multiple side brushes 700, in this embodiment, the dust collection connector is detachably disposed below the housing 600 and between the first side brush 710 and the second side brush 720. The dust collection connector has a confluence portion 310 that is adapted to the height of the cleaning surface and extends in the direction of arrangement of the first side brush 710 and the second side brush 720, and the inner diameter of the confluence portion 310 gradually decreases from the outside to the inside. The detachable design of the dust collection connector not only effectively improves the convenience of disassembly and assembly of the dust collection device, but also increases the flexibility of the installation position layout of the dust collection component. The design of the confluence portion 310 effectively expands the dust collection coverage of the dust collection connector, allowing a single dust collection connector to collect debris cleaned by two side brushes 700 separately or simultaneously, effectively simplifying the overall structure of the dust collection device. The design of gradually reducing the inner diameter allows the debris absorbed by the confluence portion 310 to flow into the dust collection connector and smoothly enter the dust collection box 100 through the dust collection tube 200, effectively ensuring the stability of the dust collection device.

[0036] In this embodiment, the conduit portion 310 includes a first conduit portion 311 and a second conduit portion 312 arranged opposite each other. The first conduit portion 311 extends toward the first side brush 710, while the second conduit portion 312 extends toward the second side brush 720. The first conduit portion 311 can funnel debris cleaned by the first side brush 710 into the dust collection connector, while the second conduit portion 312 can funnel debris cleaned by the second side brush 720 into the dust collection connector. This design ensures that debris cleaned by each side brush 700 is smoothly and effectively sucked into the dust collection box 100, effectively improving the coverage and dust collection efficiency of the dust collection assembly.

[0037] In this embodiment, the linear distance between the first confluence portion 311 and the second confluence portion 312 gradually decreases from the outside to the inside, with the linear distance between the two ends closer to the side brush 700 being greater than the linear distance between the two ends farther from the side brush 700. This design allows the confluence portion 310 to gradually shrink, ensuring a good confluence effect and more concentrated debris when it enters the suction connector.

[0038] In this embodiment, a 30° angle is formed between the dust suction connector and the horizontal line of the housing 600, so that the height of the confluence portion 310 can adapt to the height of the cleaning surface. It is worth noting that the size of the angle can be designed according to actual needs.

[0039] In this embodiment, the dust collection connector includes a manifold 300, a mounting sleeve 400, a connecting sleeve 500, and a dust collection port extending through the manifold 300, the mounting sleeve 400, and the connecting sleeve 500. By configuring the dust collection connector as a split structure, maintenance and assembly / disassembly of the various components are more convenient. Furthermore, the position of the dust collection port can be adjusted synchronously with the installation position of the dust collection connector, thereby increasing the flexibility of dust collection component layout.

[0040] In this embodiment, the conduit tube 300 is a hollow structure. The first and second conduit sections 311, 312 are curved surfaces, located at the end of the conduit tube 300 near the side brush 700 and arranged in a figure-eight pattern. The other end of the conduit tube 300 is detachably connected to and communicates with the dust collection tube 200. This design allows users to select conduit tubes 300 of different specifications based on actual needs to accommodate applications with varying spacing between multiple side brushes 700, effectively improving the practicality and adaptability of the dust collection device.

[0041] To achieve a detachable connection between the dust collection connector and the housing 600, in this embodiment, a mounting sleeve 400 is provided between the manifold 300 and the dust collection tube 200. The mounting sleeve 400 is provided with a connector 410 for detachably connecting to the housing 600. The manifold 300 is detachably connected and communicates with the dust collection tube 200 via the mounting sleeve 400. This design ensures a reliable connection between the dust collection connector, the dust collection tube 200, and the housing 600, and ensures the stability of the dust collection device during operation.

[0042] In this embodiment, the connector 410 is integrally formed with the mounting sleeve 400 and arranged in an annular pattern around the circumference of the mounting sleeve 400. The connector 410 is provided with a plurality of connection holes 411 arranged along the circumference of the mounting sleeve 400. The mounting sleeve 400 is removably connected to the housing 600 via the connection holes 411. The design of these connection holes 411 allows the user to achieve multiple points of connection between the two by assembling fasteners, ensuring a secure connection while also facilitating assembly, disassembly, and maintenance. Furthermore, the design of these multiple connection holes 411 allows the dust collector connector to be removably connected to the housing 600 in various positions, thereby increasing the flexibility of the dust collector connector's installation.

[0043] In this embodiment, the mounting sleeve 400 is a hollow structure, one end of which is detachably connected to and communicates with the manifold 300, and the other end of which is detachably connected to and communicates with the dust collection pipe 200. This design ensures the smooth flow of the dust collection channel and simplifies the overall structure of the dust collection assembly.

[0044] To further enhance the stability of the connection between the dust collection connector and the dust collection tube 200, in this embodiment, a connecting sleeve 500 is provided between the mounting sleeve 400 and the dust collection tube 200. The connecting sleeve 500 is a hollow structure, with one end detachably mounted on the mounting sleeve 400 and the other end mounted on the dust collection tube 200. This design ensures a secure connection between the dust collection connector and the dust collection tube 200 while facilitating assembly, disassembly, and maintenance of the mounting sleeve 400.

[0045] In this embodiment, the connecting sleeve 500 and the dust suction pipe 200 are connected by bonding.

[0046] In this embodiment, the mounting sleeve 400 has threaded portions at both ends. One end extends into the manifold 300 and is threadedly connected thereto, while the other end extends into the connecting sleeve 500 and is threadedly connected thereto. Both the manifold 300 and the connecting sleeve 500 are internally threaded. This threaded connection design further enhances the ease of assembly, disassembly, and maintenance of the vacuum connector.
