Description

Technical Field

[0001] This utility model relates to the field of sweeping robots, specifically a rotating cleaning mechanism and a sweeping robot thereof. Background Technology

[0002] Since robotic vacuum cleaners primarily rely on their built-in rotating cleaning mechanisms for floor cleaning, the brushes of these mechanisms inevitably wear down over time. As a key component that directly contacts the floor and performs the cleaning function, the wear and tear of the brushes directly affects the cleaning effect. Once the brushes are damaged due to prolonged use, it not only reduces cleaning efficiency and quality but may also prevent the robotic vacuum cleaner from thoroughly removing dirt and dust, thus impacting the overall cleaning performance. Therefore, regularly inspecting and replacing worn brushes is essential, although replacing brushes on existing robotic vacuum cleaners is inconvenient.

[0003] Therefore, we propose a rotating cleaning mechanism and its sweeping robot to solve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rotating cleaning mechanism and a sweeping robot thereof.

[0005] This utility model provides a rotating cleaning mechanism, including a mounting plate. A drive shaft is symmetrically rotatably connected to the mounting plate. One end of the drive shaft is embedded with a mounting hole. A cleaning shaft is installed in the mounting hole. Brush strips are installed on the cleaning shaft at equal angles. A sliding sleeve is slidably connected to the outside of the drive shaft. A clearance hole is provided on the side wall of the drive shaft opposite to the mounting hole. A spring is installed on the side wall of the drive shaft opposite to the clearance hole. A positioning post is provided on the spring. A positioning hole that cooperates with the positioning post is provided on the cleaning shaft. A reset device for driving the sliding sleeve to reset is installed on the cleaning shaft. A drive device for driving the drive shaft to rotate is installed on the mounting plate.

[0006] Preferably, the driving device includes a motor fixed at the center of one side of the mounting plate, a driving gear fixedly connected to the output shaft of the motor, a reversing gear symmetrically rotatably connected to the mounting plate via a rotating shaft, a driven gear fixed on the driving shaft, and the reversing gear meshing with the corresponding driving gear and driven gear.

[0007] Preferably, the drive gear is driven by an electric motor, which in turn drives the reversing gear, which in turn drives the driven gear, drive shaft, and cleaning shaft to rotate together.

[0008] Preferably, the drive device reset device includes a spring sleeved on the outside of the drive shaft, with both ends of the spring connected to the driven gear and the sliding sleeve, respectively.

[0009] Preferably, the cleaning shaft sidewall is symmetrically provided with guide rails, and the inner wall of the clearance hole is provided with guide grooves that slide with the guide rails to ensure that the positioning post and the positioning hole can be quickly aligned.

[0010] Preferably, the inlet of the positioning hole is chamfered to facilitate the installation of the positioning post into the positioning hole.

[0011] When disassembling the cleaning shaft, press the sliding sleeve inside the housing. The spring plate is released from the compression of the sliding sleeve and returns to its original position along the clearance hole under its own elastic force (the spring is compressed). The positioning pin is released from the positioning hole, and the cleaning shaft is pulled out of the mounting hole to complete the disassembly.

[0012] When installing the cleaning shaft, press the sliding sleeve inside the housing. The spring plate is released from the compression of the sliding sleeve and returns to its original position along the clearance hole under its own elastic force (the spring is compressed). Insert the cleaning shaft along the mounting hole and ensure that the guide rail is aligned with the guide groove. After the cleaning shaft is installed in place, release the cleaning shaft. Under the force of the spring, the sliding sleeve re-compresses the spring plate, so that the positioning pin is installed in the positioning hole, thereby locking the cleaning shaft.

[0013] A robotic vacuum cleaner includes a rotating cleaning mechanism, a housing, and a sealing cover mounted on the bottom of the housing. The mounting plate is fixed inside the housing, and the sealing cover has a through hole for avoiding a sliding sleeve.

[0014] Compared with related technologies, the present invention provides the following beneficial effects:

[0015] Easy to install and maintain: The design of the sliding sleeve, spring, positioning post, and positioning hole makes the installation and removal of the sweeping shaft exceptionally simple, greatly reducing the user's maintenance costs and time. At the same time, this design also facilitates regular inspection and replacement of the brush strips, ensuring consistently stable cleaning performance. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1 to 4 A rotary cleaning mechanism, the core component of which includes a sturdy mounting plate 1. Two drive shafts 2 are symmetrically rotatably connected to this mounting plate 1, one end of which is cleverly embedded in mounting holes 3, specifically designed to accommodate a sweeping shaft 4. Brush strips 5 are arranged at equal angles on the sweeping shaft 4 to ensure that the cleaning work is performed evenly and efficiently.

[0024] To facilitate easy assembly and disassembly of the sweeping shaft 4, a sliding sleeve 6 is cleverly slidably connected to the outer side of the drive shaft 2. On the side wall of the drive shaft 2, a clearance hole 7 is provided directly opposite the mounting hole 3. Adjacent to the clearance hole 7, a highly elastic spring piece 8 is installed. A positioning post 9 is cleverly designed on the spring piece 8, which cooperates with the positioning hole 10 on the sweeping shaft 4. This design ensures the stability of the sweeping shaft 4 after installation.

[0025] To facilitate the smooth reset of the sliding sleeve 6 during disassembly and assembly, a reset device 11 is carefully installed on the cleaning shaft 4. This reset device mainly consists of a spring 17 sleeved on the outside of the drive shaft 2, with both ends of the spring 17 tightly connected to the driven gear 16 and the sliding sleeve 6, respectively. When the sliding sleeve 6 is subjected to external force, the spring 17 deforms, providing necessary cushioning for the movement of the sliding sleeve 6, and pushing it to reset after the external force disappears.

[0026] To ensure quick and accurate alignment between the positioning post 9 and the positioning hole 10, guide rails 20 are symmetrically arranged on the side wall of the cleaning shaft 4, while the inner wall of the clearance hole 7 is correspondingly provided with guide grooves 21 that slide with the guide rails 20. This design not only improves the accuracy of positioning but also makes the installation and disassembly of the cleaning shaft 4 smoother. In addition, a chamfer 22 is carefully provided at the entrance of the positioning hole 10, a detail that greatly simplifies the installation process of the positioning post 9.

[0027] When disassembling the cleaning shaft 4, the user only needs to gently press the sliding sleeve 6 inside the housing 23. The spring piece 8 will then disengage from the sliding sleeve 6 and return to its original position along the clearance hole 7 under its own elastic force (at this time, the spring 17 will be compressed to a certain extent). As the spring piece 8 returns to its original position, the positioning pin 9 will also easily disengage from the positioning hole 10, and the user can then smoothly pull the cleaning shaft 4 out of the mounting hole 3 to complete the disassembly process.

[0028] The installation of the cleaning shaft 4 is equally simple. The user needs to press the sliding sleeve 6 into the housing 23 again to reset the spring 8. Then, slowly insert the cleaning shaft 4 along the mounting hole 3, ensuring that the guide rail 20 and the guide groove 21 are precisely aligned. Once the cleaning shaft 4 is in place, release the hand, and the spring 17 will exert its force, pushing the sliding sleeve 6 to press the spring 8 again, so that the positioning pin 9 is firmly installed in the positioning hole 10, thereby achieving a secure lock of the cleaning shaft 4.

[0029] Please refer to the following: Figures 1 to 4 A robotic vacuum cleaner includes a rotating cleaning mechanism, a housing 23, and a sealing cover 19 mounted on the bottom of the housing 23. The mounting plate 1 is fixed inside the housing 23, and the sealing cover 19 has a through hole 18 for avoiding the sliding sleeve 6.
