The working principle of telescopic cleaning tool mainly includes two parts: magnetic attraction and retractable structure.
Working principle of telescopic cleaning tool
The design of telescopic cleaning tool allows it to be retracted as needed, so as to adapt to different usage scenarios and the height of the user. Its working principle is mainly achieved by combining magnetic attraction and retractable structure:
Magnetic attraction: The magnetic adsorption part is usually located at the bottom of the broom, close to the ground, and is used to adsorb and fix the working surface of the broom. This part uses magnets as the adsorption source. When the broom is close to the ground, the magnet generates a magnetic field and adsorbs the ground. Through the magnetic attraction between the ground and the magnet, the broom is fixed on the ground, making it difficult to slide.
Retractable structure: The telescopic rod part is the main load-bearing part of the broom, which is composed of multiple telescopic rod segments. Each telescopic rod segment is connected together by a special combination method, so that it can slide and retract freely. The telescopic rod usually realizes the telescopic function in the following two ways:
Threaded connection: One end of the telescopic rod is provided with a thread, and the other end is provided with a corresponding threaded hole. When the user rotates the telescopic rod, the telescopic rod sections will slide relative to each other under the action of the thread, thereby changing the length of the broom.
Gear mechanism: A gear is provided at one end of the telescopic rod, and the gear is equipped with a corresponding gear rack. By rotating the telescopic rod, the gear will drive the gear rack to slide relative to each other, thereby changing the length of the broom. This method is usually smoother and more convenient to operate.
