Description

Technical Field

[0001] This utility model relates to the field of test tube brush technology, specifically to a novel portable test tube brush. Background Technology

[0002] A test tube brush, also known as a twisted wire brush, straw brush, pipe brush, or through-hole brush, is a cleaning tool consisting of a metal frame (such as stainless steel wire) and spirally wound bristles. Test tube brushes are widely used in laboratories, industries, and medical fields, and are mainly used to clean the inner walls of test tubes, pipes, etc.

[0003] Traditional test tube brushes typically use wire as a frame, with the bristles held in place by twisting. These brushes rely on manual rotation for cleaning. The fine, spirally wound end creates a rigid, slender rod, resulting in insufficient effective contact area when gripped. In practice, the user's fingertips must apply continuous force across the narrow contact surface, which is prone to slipping due to the smooth metal surface and significantly reduces efficiency due to the lack of cushioning. This design also poses safety hazards; repeated use can cause wear and tear on gloves or skin, and precise force control during rotation is difficult, affecting the cleaning effect and lifespan of laboratory equipment. Therefore, a novel portable test tube brush is proposed. The outer bristle-covered structural column is connected to the bottom of a conical handle via a plug and groove, facilitating easy connection and disassembly. The brush is held by a conical handle that is narrower at the top and wider at the bottom, making it easy to move the brush head. Utility Model Content
