[0001] The utility model relates to the field of flask brushes, in particular to a flask brush with a replaceable brush head. Background Art
[0002] A flask brush is a tool designed for cleaning laboratory flasks and other utensils. It typically consists of a long stem, a brush head, and a handle. The brush head can be made of either a cleaning brush or wire, providing excellent cleaning results and removing even the most stubborn dirt. The stem provides the necessary length and flexibility for deep cleaning inside flasks. The handle is designed for comfort and ease of use. A flask brush is an essential cleaning tool in the laboratory, ensuring the hygiene and effectiveness of laboratory equipment.
[0003] A search revealed a Chinese patent application titled "A Flask Brush," with authorization number CN205696410U. The utility model provides a flask brush comprising a support bar conforming to the inner wall of a flask, a brush strip embedded within the support bar along its length, and an L-shaped rotating shaft fixed to the upper end of the support bar, extending outward from the flask. The top end of the rotating shaft is threadedly connected to a rotating handle. This utility model has the beneficial effects of avoiding blind spots while ensuring thorough cleaning of the flask interior. Furthermore, the brush strip is embedded within the support bar, allowing it to be replaced independently if damaged or worn, while the support bar remains in use. This improves component utilization and conserves resources.
[0004] Since the shapes and depths of the flasks are different, after replacing the brush strip on the support bar alone, its shape will not change and it cannot be adjusted. Therefore, the cleaning effect is not good for some irregular flasks or flasks with narrow openings and wide inner cavities, and it is impossible to achieve all-round cleaning inside the flask.
[0005] Therefore, a flask brush with a replaceable brush head is proposed to solve the above problems. Utility Model Content
[0006] The purpose of the utility model is to provide a flask brush with a replaceable brush head in order to solve the above problems, thereby improving the problems that traditional flask brushes cannot be used for flasks with different inner diameters, and the brush head cannot be replaced, making cleaning inconvenient.

[0026] When the staff needs to clean the flask, they first hold the handle 2 to insert the cleaning brush 303 into the interior of the flask. At this time, the cleaning brush 303 is in an upright position and can scrub the bottom and the inner wall of the bottle mouth of the flask. At the same time, the positioning sleeve 304 is also sleeved on the surface of the connection between the limiting rod 308 and the rotating shaft of the connecting seat 302, which can prevent the limiting rod 308 and the connecting seat 302 from bending and affecting the stability of the cleaning brush 303.
[0027] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the adjustment component 3 includes a movable shell 301 movably connected to the end of the vertical rod 1 through a rotating shaft, the inner cavity of the movable shell 301 is slidably connected to the limit rod 308, the end of the limit rod 308 away from the vertical rod 1 is movably connected to the connecting seat 302 through a rotating shaft, and a cleaning brush 303 is provided on the side of the connecting seat 302 away from the limit rod 308. The surface of the limit rod 308 is provided with a positioning sleeve 304, and the inner cavity of the positioning sleeve 304 is in contact with the limit rod 308 and the connecting seat 302 respectively; the surface of the movable shell 301 is movably connected to the adjustment rod 306 through a rotating shaft, and the adjustment rod 306 is movably connected to the adjustment rod 306. The end of 06 away from the movable shell 301 is movably connected to the sliding shell 305 through a rotating shaft, and the inner cavity of the sliding shell 305 is in contact with the vertical rod 1; a connecting rod is provided on the surface of the sliding shell 305, and the end of the connecting rod away from the sliding shell 305 is fixedly connected to the toggle block 307; the outer diameter of the limiting rod 308 is equal to the inner diameter of the movable shell 301, and the surface of the limiting rod 308 is tightly fitted with the inner cavity of the movable shell 301; the heights of the rotating shaft connections at both ends of the adjusting rod 306 are inconsistent, and the rotating shaft connection of the adjusting rod 306 close to the sliding shell 305 is higher than the rotating shaft connection close to the movable shell 301;
[0028] When the cleaning brush 303 needs to be cleaned, the cleaning brush 303 is first moved to the surface of the limit rod 308, and then the extension length of the limit rod 308 inside the movable shell 301 is adjusted, and the cleaning brush 303 can be inserted into the flask. After the cleaning brush 303 is inserted, the staff will use the toggle block 307 to cooperate with the connecting rod to pull the sliding shell 305 upward. At this time, the adjusting rod 306 moves up with the sliding shell 305, and the movable shell 301 at the lower end of the adjusting rod 306 is pulled to a parallel state by the adjusting rod 306. At this time, the cleaning brush 303 is still kept upright by contact with the inner wall of the flask or its own gravity.
