Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning tools, in particular to a double-brush-head multifunctional lint scraper shovel suitable for cleaning various surfaces, which can efficiently clean surfaces of different materials such as carpets, fabrics, glass, and ceramic tiles. BACKGROUND

[0002] The lint scraper shovel is a cleaning tool widely used on surfaces such as fabrics, carpets, and furniture. Its core function is to remove lint, pet hair, dust, and other impurities attached to the surface of an object through the scraping action of the brush head. Traditional lint scrapers are usually composed of a handle and a fixed brush head. The brush head is made of hard plastic or metal, and the bristles are arranged in a straight or wavy line. The target surface is cleaned by one-way or reciprocating scraping through handheld operation.

[0003] The basic structure of the existing lint scraper includes:

[0004] 1. Rigid body: mostly made of one-piece plastic or metal plate, with a single row of bristles or scraping teeth on the surface;

[0005] 2. Fixed brush head: the bristles are made of a single material, commonly stainless steel or nylon, suitable for specific surfaces such as carpets or fabrics;

[0006] 3. Straight or curved handle design: the handle is fixedly connected to the main body, usually 15-30 cm in length to meet the needs of handheld operation.

[0007] However, the traditional lint scraper has the following limitations:

[0008] 1. Single function: a single hard brush head cannot meet the cleaning needs of rough surfaces (such as carpets) and smooth surfaces (such as glass), so users need to purchase multiple tools;

[0009] 2. Structural strength defects: wide brush surfaces (more than 20 cm) are prone to bending or breaking due to lack of reinforcement, resulting in reduced service life;

[0010] 3. Poor human-machine ergonomics: the fixed handle design cannot adapt to different cleaning scenarios (such as high places or narrow gaps), and lacks anti-slip or grip angle adjustment functions.

[0011] For example, the "carpet lint scraper" disclosed in patent CN222114987U uses a single-sided metal bristle design, which can effectively remove lint, but the rigid plastic body is prone to breaking in the middle after repeated force; the "replaceable brush head cleaning shovel" proposed in patent CN222154991U achieves the function of replacing the brush head, but the replacement process requires disassembling screws, which is cumbersome and cannot simultaneously retain the synergistic effect of the double brush heads.

[0012] Therefore, it is necessary to design a reinforced scraping shovel and expand its use function. Content of the utility model
