Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a dust collection structure that facilitates waste separation. Background Technology

[0002] With the widespread adoption of smart home devices, robotic vacuum cleaners have become a common automated cleaning tool in modern homes and commercial spaces. However, existing robotic vacuum cleaners generally suffer from the following technical bottlenecks: First, traditional waste collection devices often employ open or semi-closed structures, which can easily cause dust to scatter due to airflow disturbances during waste suction and temporary storage, resulting in secondary environmental pollution and potentially the spread of allergens. Second, the separation efficiency between waste and air is low, especially in terms of filtering fine particles, which can easily lead to filter clogging and difficulty in thorough cleaning with prolonged use. Third, the sealing performance between the waste bin and the main body is poor, and the negative pressure system is prone to air leakage, leading to a decrease in suction power and affecting overall cleaning efficiency. Fourth, the maintainability of existing structures is poor, with cumbersome disassembly and assembly of the waste bin lacking effective guidance, resulting in a poor user experience.

[0003] Specifically, the dustbin of traditional robotic vacuum cleaners is usually directly exposed in the airflow channel, lacking an independent filtration component for sorting and processing waste. This results in the accumulation of large particles mixed with fine dust, reducing the utilization rate of the dust collection capacity and increasing the difficulty of subsequent cleaning. Furthermore, the connection between the dustbin and the machine body often relies on simple snap-fit ​​or threaded fastening, lacking a reliable sealing design. Under negative pressure, gaps can easily form due to deformation or vibration, causing airflow leakage and waste spillage. In addition, although some models in the current technology are equipped with suction pipes, they do not form a complete closed negative pressure system, failing to effectively control the dust diffusion path at the source.

[0004] To address the aforementioned technical challenges, there is an urgent need for a novel dust collection structure that can achieve efficient waste separation, fully enclosed dust control, excellent sealing performance, and easy maintenance, thereby improving the environmental performance and reliability of cleaning robots. This utility model is proposed based on this technical need. Utility Model Content

[0024] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figure 1-7 As shown, this embodiment provides a dust collection structure that facilitates garbage separation, including a cleaning robot body 1, drive wheels 2, front auxiliary wheels 3, rear auxiliary wheels 4, side brushes 5, cleaning brushes 6, a dustbin 7, a filter assembly 8, a dust collection assembly 9, and a suction pipe 10; the drive wheels 2, front auxiliary wheels 3, and rear auxiliary wheels 4 are all located at the bottom of the cleaning robot body 1, the cleaning brushes 6 are located at the bottom of the cleaning robot body 1, the side brushes 5 are located on the left and right sides of the cleaning robot body 1 in the forward direction, the dustbin 7, the filter assembly 8, and the dust collection assembly 9 are all located in the cleaning robot body 1, the dustbin 7 is located behind the cleaning brushes 6, the filter assembly 8 is located at the entrance of the dustbin 7, and the two ends of the suction pipe 10 are connected to the filter assembly 8 and the dust collection assembly 9, respectively.

[0027] In this embodiment, there are two drive wheels 2, symmetrically arranged on both sides of the sweeping robot body 1 in the forward direction. The front auxiliary wheels 3 are located at the bottom front of the sweeping robot body 1, and there are two rear auxiliary wheels 4, symmetrically arranged on both sides of the rear of the sweeping robot body 1 in the forward direction. Two side brushes 5 collect debris and dust along the path of the sweeping robot body 1, and then sweep them into the dustbin 7 using cleaning brushes 6. The dust collection component 9, in conjunction with the suction pipe 10 and filter component 8, collects the dust, preventing it from being stirred up by the sweeping robot body 1 and causing further pollution.

[0028] The filter assembly 8 includes a fixed housing 80, which is disposed inside the cleaning robot body 1. A filter box 83 is located inside the fixed housing 80, and a connecting pipe 81 is located on the outside of the fixed housing 80. The connecting pipe 81 communicates with the interior of the filter box 83 and is connected to the suction pipe 10. Through its connection to the suction pipe 10, the connecting pipe 81 stably guides the airflow and pre-filtered debris from the filter box 83 within the fixed housing 80 into the dust collection assembly 9, ensuring that negative pressure suction is effectively transmitted to the filter box area and providing a pathway for debris suction.

[0029] The trash can 7 includes a collection box 70, with a handle 71 on one side and a guide plate 73 on the other side. An inlet slot 82 is located below the fixed housing 80, and the guide plate 73 is positioned below the inlet slot 82. A filter slot 84 is opened at the bottom of the filter box 83. The guide plate 73 guides the trash swept by the cleaning brush 6 to the vicinity of the inlet slot 82, facilitating its smooth entry into the inlet slot 82. The open filter slot 84 at the bottom of the filter box 83 allows fine trash and dust passing below the filter box 83 to pass through and enter the filter box 83, while larger trash falls directly into the collection box 70, achieving preliminary separation and filtration of trash and airflow.

[0030] The top of the collection box 70 is equipped with a buckle 72. The buckle 72's latch is fixed to the top of the collection box 70, and the buckle seat is fixed to the top of the fixing housing 80. By fixing the buckle 72 to the top of the collection box 70 with the latch and the buckle seat to the top of the fixing housing 80, the collection box 70 can be quickly fixed to the fixing housing 80. At the same time, it is easy to manually unfasten the buckle, realizing convenient assembly and disassembly of the collection box 70 and facilitating the cleaning of the collected waste.

[0031] A rubber pad 85 is provided on one side of the fixed housing 80, and a baffle 74 is integrally formed on one side of the collection box 70. The rubber pad 85 and the baffle 74 are pressed together. The pressing fit between the rubber pad 85 and the baffle 74 can enhance the sealing performance between the collection box 70 and the fixed housing 80, prevent garbage from leaking from the gap between them during the collection process, reduce the loss of negative pressure suction, and ensure dust collection efficiency.

[0032] A guide post 76 is provided on one side of the fixed housing 80, and a guide sleeve 75 is provided on the baffle 74. The guide sleeve 75 is sleeved on the guide post 76. The sleeved engagement between the guide sleeve 75 and the guide post 76 provides guidance for the installation and disassembly of the collection box 70, ensuring that the collection box 70 can be accurately aligned during the installation and disassembly process, avoiding the impact of installation deviation on the sealing performance and the fastening effect of the buckle 72, and enhancing the structural stability after the two are connected.

[0033] The dust collection assembly 9 includes a dust collection box 90, a dust collection bag 91, a mounting base 92, and a negative pressure fan 93. The dust collection box 90 is fixed in the main body 1 of the cleaning robot. The dust collection bag 91 is snapped onto the mounting base 92, and the suction pipe 10 is connected to the mounting base 92. The mounting base 92 is set on the dust collection box 90, and the negative pressure fan 93 is set on the dust collection box 90. When the negative pressure fan 93 is working, it generates negative pressure, causing outside air to carry garbage through the suction pipe 10 into the mounting base 92, where it is eventually collected by the dust collection bag 91. The dust collection bag 91 is snapped onto the mounting base 92 for easy and quick replacement. The cooperation between the mounting base 92 and the dust collection box 90 ensures the stable installation of the dust collection bag 91. The dust collection box 90 protects the dust collection bag 91 and the negative pressure fan 93, forming a complete dust collection path.

[0034] In summary, this embodiment, through structural innovation and functional integration, has significant advantages in improving waste collection efficiency, suppressing dust pollution, and simplifying maintenance operations, and is suitable for high-cleanliness cleaning needs in both residential and commercial settings.
