Description

Technical Field

[0001] This utility model belongs to the field of sweepers, and specifically relates to a sweeper component. Background Technology

[0002] In the home and commercial cleaning sector, sweepers are widely used due to their automated cleaning capabilities. As users demand higher cleaning efficiency and convenience, the structural design of sweeper components is constantly being optimized. Existing sweepers achieve efficient cleaning and collection of dust and debris on the ground through the coordinated operation of various functional components. Among them, the sweeping component, moving component, and vacuuming component are the core components, and their performance directly affects the cleaning effect. The development of related technologies is driving sweepers to evolve towards a more intelligent and practical direction.

[0003] Existing technologies have specifically developed some floor vacuum cleaners, for example, those with the announcement number "HYPERLINK "https: / / www.uyanip.com / result?exp=GKH:(CN217447591U)" \t "https: / / www.uyanip.com / _blank" Chinese patent CN217447591U discloses a "high dynamic balance sweeper with a three-pronged rotating rod". This invention features a connecting shaft with a slotted groove and an annular groove at the end where it connects to the rotating shaft. A magnet is placed in the annular groove, allowing the rotating shaft to directly extend into the housing and magnetically connect to the connecting shaft. The slotted protrusion of the rotating shaft extends into the slot, achieving coaxial rotation. This magnetic connection method allows for quick assembly and disassembly of the rotating shaft in the sweeper's cleaning assembly, improving assembly and maintenance efficiency while maintaining a simple structure. Furthermore, this invention detachably connects three brush strips to the rotating shaft. When the brush strips experience severe wear or damage after prolonged use, the rotating shaft can be disassembled first, followed by the replacement of the brush strips.

[0004] Although a slot and annular groove are provided at the end of the connecting shaft that connects to the rotating shaft, and a magnet is placed in the annular groove, allowing the rotating shaft to directly extend into the housing and magnetically connect with the connecting shaft, and the slotted protrusion of the rotating shaft extends into the slot to achieve coaxial rotation; this magnetic connection method allows for quick assembly and disassembly of the rotating shaft in the sweeper's cleaning assembly, the brush strip and rotating shaft are connected by a snap-fit ​​pin, and the arc-shaped column is only limited by its outer edge. After long-term high-frequency rotation, it is prone to loosening. Vibration during cleaning may cause the snap-fit ​​pin to slip out of the locking hole and fixing hole, making the brush strip connection unstable, affecting the cleaning effect, requiring frequent inspection and reinforcement, and increasing maintenance trouble.

[0020] refer to Figure 3 A circular groove 25 is provided at the bottom of the sweeper body 9 near the guide wheel 1. A rotating rod 24 is rotatably installed inside the circular groove 25. The end of the rotating rod 24 away from the circular groove 25 is fixedly installed at the end of the rotating plate 2 away from the guide wheel 1. It can move flexibly through the guide wheel 1 and the moving wheel 7 at the bottom. The guide wheel 1 is installed between the first bracket 13 at the end of the rotating plate 2. The rotating plate 2 is rotatably connected to the circular groove 25 at the bottom of the sweeper body 9 through the rotating rod 24, and can rotate around the rotating rod 24 as the ground undulates.

[0021] refer to Figures 1 to 2 The rotating seat 12 has a mounting opening 14 at its center, and an anti-slip groove 18 inside the mounting opening 14. A driving plate 10 is located inside the mounting opening 14, and an anti-slip sleeve 17 is fixedly installed at the bottom of the driving plate 10.

An internal thread groove 15 is located at the center of the rotating shaft 16, and the screw rod 28 is threaded into the internal thread groove 15. The connecting seat 4 is threadedly connected to the rotating shaft 16 through the screw rod 28. When the driving plate 10 is rotated, the anti-slip sleeve 17 at its bottom rotates synchronously in the anti-slip groove 18 of the rotating seat 12. The torque is transmitted through the screw rod 28, causing the rotating seat 12 to rise and fall along the axial direction of the rotating shaft 16, thereby adjusting the contact pressure between the floor brush strip 3 and the ground to adapt to the cleaning needs of different floor materials.

[0022] Operating principle and advantages: During regular cleaning, the device uses the sweeper body 9 as the core load-bearing structure. It moves flexibly via the guide wheels 1 and moving wheels 7 at the bottom. The guide wheels 1 are installed between the first bracket 13 at the end of the rotating plate 2. The rotating plate 2 is rotatably connected to the circular groove 25 at the bottom of the sweeper body 9 via a rotating rod 24, allowing it to rotate around the rotating rod 24 to adjust the height of the guide wheels 1 to adapt to uneven surfaces, ensuring smooth sweeper movement. The moving wheels 7 are fixed to the upper end of the rectangular plate 6 via the second bracket 8, serving as the main load-bearing structure. The sweeper, along with its drive components and the steering function of the guide wheel 1, enables straight-line movement and steering. The core cleaning action is accomplished by the brush strips 3 and the suction port 5 working together. The suction port 5 at the center of the bottom of the sweeper body 9 is responsible for sucking dust and debris into the collection device. The brush strips 3 on both sides of the suction port 5 rotate and clean by connecting the rotating seat 12 and the rotating shaft 16. The three connecting seats 4 on the outer ring of the rotating seat 12 fix the brush strips 3 through the plug-in block 27, forming a triangular cleaning structure that can fully cover the area around the suction port 5 and remove debris from the ground. The brush moves towards the suction port 5. The connection between the rotating seat 12 and the rotating shaft 16 relies on the engagement of the lead screw 28 and the internal thread groove 15. When the rotating drive plate 10 is rotated, the anti-slip sleeve 17 at its bottom rotates synchronously within the anti-slip groove 18 of the rotating seat 12. Torque is transmitted through the lead screw 28, causing the rotating seat 12 to rise and fall axially along the rotating shaft 16, thereby adjusting the contact pressure between the brush strip 3 and the ground to adapt to the cleaning needs of different floor materials. When the brush strip 3 needs to be replaced, the snap-fit ​​structure of the device simplifies the operation process. The insertion groove 22 inside the connecting seat 4 provides a connection for the insertion block 27. The positioning track and the snap-fit ​​component 26 on one side of the plug-in block 27 enable quick fixation. Under normal conditions, the spring 21 pushes the snap-fit ​​block 20 into the slot 23 of the connector 4 to ensure stable installation of the floor brush strip 3. When replacing, press the snap-fit ​​block 20 to compress the spring 21 and return it to the slot 19. Then, the plug-in block 27 can be pulled out along the plug-in slot 22. Remove the old floor brush strip 3 and replace it with a new floor brush strip 3. Insert the plug-in block 27 into the plug-in slot 22. When the snap-fit ​​block 20 is aligned with the slot 23, the spring 21 resets and pushes the snap-fit ​​block 20 to re-engage, completing the fixation. No tools are required throughout the process.
