Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cleaning brush convenient to use more specifically, it relates to a kind of cleaning brush convenient to use. BACKGROUND

[0002] In the field of modern household cleaning and public environmental health maintenance, cleaning brush as one of the most basic and widely used cleaning tools, bears the dust, dirt removal work on the ground, wall, ceiling and other surfaces. With the improvement of people's living standards and the diversification of living environment, modern residence, commercial space and public building often design space of different heights and various concave-convex structures, such as high ceiling, ceiling lamp, corner bay window, wall decoration, deep cabinet, etc., the cleaning needs of these positions are increasingly prominent. However, in the face of these cleaning scenes with obvious height difference, the traditional fixed length cleaning brush shows obvious functional limitations. When it is necessary to clean dust or cobwebs on high places such as ceiling and ceiling lamp, the standard length cleaning brush often cannot reach, and the user has to match a ladder or a stool, which not only increases the complexity of the cleaning process, but also introduces the safety hazard of high-altitude operation. When it is necessary to clean low space such as the bottom of cabinet, under furniture or corner gap, the too long cleaning tool is heavy and inconvenient to operate flexibly, and is easy to collide with surrounding objects and cause damage. Although there are some extendable cleaning tools on the market, most of them adopt simple sleeve structure or threaded connection design. Such design often faces problems such as inconvenient adjustment, insecure locking and unexpected length change during use. Especially in complex cleaning environment where the length of the tool needs to be adjusted frequently, the adjustment mechanism of the existing cleaning brush often needs multi-step operation or two-hand cooperation, which interrupts the continuity of cleaning work, and the user needs to stop repeatedly for adjustment, which significantly reduces the cleaning efficiency.

[0003] From the perspective of tool use experience and function realization, the technical defects of the existing adjustable cleaning brush mainly lie in three aspects. First of all, in the design of adjustment mechanism, traditional extendable cleaning brush usually adopts rotating locking or button buckle type structure. Such structure is easy to wear, jam or loosen during frequent adjustment, affecting the smoothness of adjustment and the reliability of locking. Especially for the elderly, users with weak hand strength or joint problems, the operation mode of rotating locking or accurate pressing buckle with certain force increases the difficulty of use. Secondly, in the adjustment range and accuracy, the existing products usually only provide limited fixed length selection, which cannot meet the fine length requirement of different users in various cleaning scenes. For example, in the case of cleaning wall decoration of different heights or cleaning inclined roof, the ideal tool length may fall between two fixed positions, forcing the user to make a compromise between not reaching and being too long.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a cleaning brush convenient to use, has the following

[0017] Advantages:

[0018] This innovative easy-to-use cleaning brush effectively solves the technical problem of inconvenient adjustment of traditional cleaning tools in different height cleaning scenarios through the unique bidirectional self-locking adjustment mechanism design, providing users with a multifunctional cleaning tool that is easy to operate, accurately adjusted, and firmly locked. The core innovation of this cleaning brush is its unique bidirectional self-locking adjustment system. Users can quickly unlock and adjust the tool length by simply pinching with one hand. After releasing, the system automatically locks, ensuring the length remains stable during cleaning. Its working principle is to set symmetrical self-locking mechanisms between the telescopic rod and the fixed tube. When the user pinches the bidirectional control device in the middle of the handle, the internal transmission system drives the locking block to move outward simultaneously, temporarily releasing the locking of the telescopic rod. At this time, the user can freely adjust the telescopic rod length. After adjusting to the desired position, release the control device. The internal elastic element will drive the locking block to return and tightly fit on the surface of the telescopic rod, forming a firm friction lock. This locking force will automatically increase in the direction of force, achieving stable and reliable bidirectional self-locking effect.

[0019] This design improves the functionality and user experience of the cleaning brush from multiple dimensions. From the perspective of operational convenience, this cleaning brush achieves true one-handed adjustment. Users can adjust the length by pinching while holding the tool, without needing to put down the tool, change hand positions, or use both hands. This significantly improves the continuity and efficiency of the cleaning process. Especially for complex cleaning environments that require frequent length adjustment, such as staircases, multi-level structures, or uneven surfaces, this convenient adjustment method can significantly reduce operation steps and time costs.

[0030] In the embodiment, when cleaning with the brush head 1, the distance between the telescopic rod 5 and the fixed rod needs to be adjusted for different positions, so as to adapt to different situations. First, pinch the two bidirectional discs 13, so as to drive the two bidirectional discs 13 to move close to each other, then drive the two synchronous rings 16 at the two ends to move towards each other. Since the plurality of steering springs 10 are connected to the synchronous rings 16 respectively, the plurality of self-locking blocks 8 are driven to expand and move towards the position of the bidirectional disc 13 synchronously. At this time, the plurality of self-locking blocks 8 are away from each other, and then leave the telescopic rod 5. At this time, the position of the telescopic rod 5 can be adjusted.

Since the self-locking blocks 8 at the two ends are attached to the telescopic rod 5 respectively, and no matter which end is pulled, self-locking is formed, thereby ensuring the stability of fixation.

[0032] In summary, when the overall device is in use or operation: when cleaning with the brush head 1, the distance between the telescopic rod 5 and the fixed rod needs to be adjusted for different positions, so as to adapt to different situations. First, pinch the two bidirectional discs 13, so as to drive the two bidirectional discs 13 to move close to each other, then drive the two synchronous rings 16 at the two ends to move towards each other. Since the plurality of steering springs 10 are connected to the synchronous rings 16 respectively, the plurality of self-locking blocks 8 are driven to expand and move towards the position of the bidirectional disc 13 synchronously. At this time, the plurality of self-locking blocks 8 are away from each other, and then leave the telescopic rod 5. At this time, the position of the telescopic rod 5 can be adjusted. After adjustment, the bidirectional disc 13 can be released, so that the plurality of self-locking blocks 8 are reset and pressed on the telescopic rod 5, thereby ensuring the fixation of the telescopic rod 5.

[0033] After adjustment, the self-locking blocks 8 are ensured to shrink along the self-locking grooves 7 under the action of the intermediate spring 15, so that the self-locking blocks 8 at the two ends are pressed on the telescopic rod 5 respectively. Since the self-locking blocks 8 at the two ends are attached to the telescopic rod 5 respectively, and no matter which end is pulled, self-locking is formed, thereby ensuring the stability of fixation.
