[0002] Cleaning robots are intelligent devices that utilize sensor fusion, artificial intelligence algorithms, and automated control systems to achieve environmental perception, path planning, and autonomous cleaning. They are primarily used in home, commercial, and industrial settings, covering diverse cleaning needs such as floors, swimming pools, and building exteriors.

[0003] Patent publication number CN221285620U specifically relates to a cleaning robot, including a body, a drive wheel assembly, and a fan. The fan is mounted on the body, and the drive wheel assembly includes two opposing drive wheels with rubber layers on their surfaces. A suspension structure is provided between the two drive wheels and the body, forming a buffer area between the two drive wheels. The fan is installed within this buffer area. While this patent allows the vibrations generated by the fan to be promptly transmitted to the suspension structure by placing it within the buffer area between the two drive wheels, and the suspension structure between the drive wheels and the body can significantly absorb most of the fan's vibrations, in actual use, dust is generated during cleaning, causing it to disperse and increasing the difficulty of thorough cleaning while failing to achieve the ideal effect of efficient dust removal.

[0004] Therefore, a cleaning robot with a dust removal structure is needed. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents, which generate dust during cleaning and cause dust to scatter, thus increasing the difficulty of thorough cleaning and making it difficult to achieve the ideal effect of efficient dust removal, this utility model provides a cleaning robot with a dust removal structure.

[0006] The technical implementation scheme of this utility model is as follows: a cleaning robot with a dust removal structure includes a shell, a bottom cover, drive wheels, a top cover, a control module, steering wheels, an electric sweeping roller, and a dust collection structure. The bottom cover is provided at the bottom of the shell, and two drive wheels are installed on the bottom cover. The top cover is provided at the top of the shell, and the control module is provided on the bottom cover. The steering wheels are provided on the bottom cover, and the electric sweeping roller is rotatably installed on the bottom cover. The dust collection structure is provided on the bottom cover for adsorbing fine dust and lightweight debris. It also includes a water tank, a pipeline pump, a water outlet hose, and a nozzle. The water tank is fixedly connected to the bottom cover, the pipeline pump is installed on the top of the water tank, and the bottom of the water tank is connected to and communicates with the water outlet hose.

[0011] Optionally, the nozzle tip is funnel-shaped.

[0012] Compared with the prior art, this utility model provides a cleaning robot with a dust removal structure, which has the following beneficial effects: 1. The pipeline pump is started to pump water out of the water storage tank and deliver it to the nozzle through the water outlet hose. The nozzle sprays water on the ground in the working area of ​​the sweeping roller or near the suction nozzle, thereby pre-wetting the ground or suppressing the dust generated during sweeping, making the dust particles heavier and less likely to be scattered, and easier to be swept up by the sweeping roller or sucked away by the suction nozzle, so as to achieve the purpose of efficient dust removal.

[0013] 2. The output shaft of the servo motor rotates, driving the second shaft to rotate. The rotation of the second shaft drives the toggle block to rotate. The toggle block periodically moves the contact block. The contact block is moved, causing the first shaft to rotate. At the same time, the torsion spring is deformed. The rotation of the first shaft causes the toggle frame to swing, thereby causing the nozzle to swing and expanding the water spray range.

[0014] 3. By rotating the sweeping bar, it assists the electric sweeping roller in cleaning, sweeping dust and debris from wall edges, corners, and other areas that the electric sweeping roller cannot reach, thus improving the overall cleaning effect. Attached Figure Description

Detailed Implementation

[0023] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] Example 1: A cleaning robot with a dust removal structure, please refer to... Figures 1-7The system includes an outer shell 1, a bottom cover 2, drive wheels 201, a top cover 3, a control module 4, steering wheels 5, an electric sweeping roller 6, and a dust collection mechanism. The bottom cover 2 is located at the bottom of the outer shell 1, and two drive wheels 201 are mounted on it. The top cover 3 covers the top of the outer shell 1. The control module 4 is located on the bottom cover 2, and the steering wheels 5 are also mounted on it. The electric sweeping roller 6 is rotatably mounted on the bottom cover 2. The dust collection mechanism is used to absorb fine dust and lightweight debris. The dust collection mechanism includes a mounting shell 7, a dust collection fan 8, a dust collection pipe 9, and a suction nozzle 10. The mounting shell 7 is fixedly connected to the bottom cover 2. The device is equipped with a vacuum fan 8, with a vacuum pipe 9 connected to the top of the vacuum fan 8. One end of the vacuum pipe is connected to a nozzle 10. A water tank 11 is fixedly connected to the bottom cover 2. A pipeline pump 12 is installed on the top of the water tank 11. A water outlet hose 13 is connected to the bottom of the water tank 11. One end of the water outlet hose 13 is equipped with a nozzle 14. Several heat dissipation holes 27 are opened at the bottom of the bottom cover 2 to dissipate the heat generated by the control module 4, vacuum fan 8, pipeline pump 12 and other electronic components during operation, so as to ensure stable operation of the equipment. The top of the nozzle 10 is funnel-shaped to enhance the air collection efficiency and improve the adsorption effect.

[0025] When the cleaning robot is needed, under the command of the control module 4, the robot moves autonomously on the ground via the drive wheels 201 and steering wheels 5. The electric sweeping roller 6 rotates at high speed, sweeping up dust, debris, hair, and other objects on the ground. The vacuum fan 8 operates, generating a strong negative pressure at the suction nozzle 10. The suction nozzle 10 sucks up fine dust and light debris from the ground and transports them to the dust collection box for centralized collection through the suction pipe 9. During the cleaning process, the pipeline pump 12 is activated to pump water from the water tank 11 and deliver it to the spray nozzle 14 through the water outlet hose 13. The spray nozzle 14 sprays water onto the working area of ​​the sweeping roller or the ground near the suction nozzle 10, thereby pre-wetting the ground or suppressing the dust generated during cleaning, making the dust particles heavier and less likely to disperse, and easier to be swept up by the sweeping roller or sucked away by the suction nozzle 10, achieving the purpose of efficient dust removal. In addition, for minor stains, spraying water can soften and dissolve them, and together with the friction of the sweeping roller, improve the cleaning effect.

[0026] Example 2: Based on Example 1, please refer to... Figures 4-7The bottom cover 2 has two fixed seats 15 fixedly connected to its bottom. A first rotating shaft 16 is rotatably mounted on the fixed seat 15. The two first rotating shafts 16 are fixedly connected to a toggle frame 17, which can contact the nozzle 14. A torsion spring 18 is sleeved on the first rotating shaft 16. The two ends of the torsion spring 18 are respectively connected to the fixed seat 15 and the first rotating shaft 16. A contact block 19 is fixedly connected to one end of the first rotating shaft 16. A servo motor 20 is installed on one side of the electric cleaning roller 6. A second rotating shaft 21 is rotatably mounted on the bottom cover 2. The output shaft of the servo motor 20 and the second rotating shaft 21 are sleeved together with a pulley assembly 22. Both ends of the second rotating shaft 21 are fixedly connected to toggle blocks 23, which can move the contact block 19.

[0027] When the nozzle 14 sprays water mist, the servo motor 20 is started. The output shaft of the servo motor 20 rotates, driving the second rotating shaft 21 to rotate through the pulley assembly 22. The rotation of the second rotating shaft 21 drives the toggle block 23 to rotate. The toggle block 23 periodically moves the contact block 19. The contact block 19 is moved, causing the first rotating shaft 16 to rotate. At the same time, the torsion spring 18 is deformed. The rotation of the first rotating shaft 16 causes the toggle frame 17 to swing, thereby causing the nozzle 14 to swing and expand the water spray range. When the toggle block 23 moves away from the contact block 19, the torsion spring 18 releases its elastic force, causing the first rotating shaft 16 and the toggle frame 17 to reset, waiting for the next toggle block 23 to move.

[0028] Please see Figure 2 , Figure 4 and Figure 5 The bottom cover 2 is provided with two third rotating shafts 24. The third rotating shafts 24 and the second rotating shaft 21 are provided with a bevel gear set 25. The bottom of the third rotating shaft 24 is fixedly connected to a sweeping rod 26.

[0029] When the second rotating shaft 21 rotates, it drives the third rotating shaft 24 to rotate through the bevel gear set 25. The rotation of the third rotating shaft 24 drives the cleaning rod 26 to rotate, assisting the electric cleaning roller 6 in cleaning. It cleans dust and debris in areas that the electric cleaning roller 6 cannot reach, such as wall edges and corners, thus improving the overall cleaning effect.

[0030] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
