Technical Field
[0001] The utility model relates to the field of laboratory equipment cleaning, in particular to a combined cleaning brush based on a container with a wide bottom. Background Art
[0002] In the laboratory, containers of various shapes are needed, and they need to be cleaned after each experiment. The cleaning of various glassware in the laboratory is crucial to the success of experimental analysis. During the cleaning process, the indispensable cleaning tool for cleaning experimental containers is the container brush.
[0003] Container brush, also called test tube brush, tube brush, straw brush, hole cleaning brush, twist wire brush, pipe brush, etc., is a widely used brush product, mainly composed of iron wire (steel wire) as the skeleton, with many neatly arranged, outward-stretched fine brush wires. Brush wire materials include nylon wire, fiber hair, pig bristle, steel wire, copper wire, abrasive wire, etc., each with different use ranges.
[0004] There are many types of experimental glassware, including test tubes and other full-diameter vessels, pipettes and other small-diameter vessels, as well as volumetric flasks, Erlenmeyer flasks and other vessels that are thin at the top and wide at the bottom. However, the container brushes currently on the market are only for a certain type of container and are generally not suitable for other types of containers. Therefore, different types of brushes are required to clean different containers. What's more, several types of experimental brushes are required to clean a type of experimental vessel. Therefore, the corners of the container cannot be effectively cleaned during cleaning, resulting in low cleaning efficiency and long cleaning time, which cannot meet the needs of actual work. Technical personnel in this field are in urgent need of an experimental brush that is easy to store and can be used for multiple purposes to improve efficiency and reduce space occupancy.
[0005] Utility model patent CN220157777U discloses a BET sample tube cleaning brush, which relates to the technical field of laboratory equipment cleaning.

[0024] The brush handle is a hollow rod-shaped structure, and a brush handle cavity 11 is provided in the hollow position inside the brush handle, and the brush handle cavity runs through the brush handle from top to bottom.
[0025] The deformable brush head includes an upper brush body 21 and a lower brush body 22, and a hinge 23 is arranged between the upper brush body and the lower brush body. The upper brush body and the lower brush body have the same structure, including an arc-shaped brush rod 24, on which a plurality of bristles 25 are arranged, and the bristles are arranged in the circumferential direction of the brush rod. Brush rod holes 26 are provided at both ends of the brush rod. The hinge connection here is mainly used to realize the rotational connection between the upper brush body and the lower brush body, which can also be realized by using a rotating shaft. The brush rod holes of the upper brush body and the lower brush body are rotatably connected by using a rotating hole. The upper brush body, the lower brush body and the hinge are generally in an outer arc structure. Usually, the length of the lower brush body is shorter than that of the upper brush body.
[0026] The tensioning structure includes a fixed ring 31, a movable strip, and a tensioner. The tensioning structure is a power structure for controlling the deformation of the deformed brush head and providing external force for the deformation of the deformed brush head. The fixed ring is installed on the brush handle, and the fixed ring is sleeved on the outside of the brush handle, or fixed at the bottom of the brush handle. The middle annular part of the fixed ring is connected to the brush handle cavity.
[0027] The upper part of the upper brush body is rotatably connected to the fixed ring, the fixed ring is provided with a mounting shaft, the brush rod hole is sleeved in the mounting shaft, the lower part of the lower brush body is rotatably connected to the bottom of the movable strip, the bottom of the movable strip is provided with a circular ring, the brush rod hole of the lower brush body is rotatably sleeved on the outside of the circular ring, the upper part of the movable strip passes through the fixed ring and extends into the brush handle cavity, the tensioner is provided on the top of the movable strip, the tensioner pulls the movable strip to move into the brush handle cavity, the movable strip drives the lower brush body to move upward, and the upper brush body and the lower brush body are in a folded state.
[0028] A bottle mouth brush 40 is arranged at the top of the brush handle, and the bottle mouth brush comprises a U-shaped groove 41, bristles are arranged inside the U-shaped groove, a threaded protrusion 42 is arranged at the bottom of the U-shaped groove, and an internal thread is arranged on the top of the brush handle, and the threaded protrusion is screwed onto the internal thread.
[0029] The combined cleaning brush also includes a fine brush 43, which is inserted into the brush handle cavity, one end of which is fixed on the threaded protrusion, and the fine brush is mainly used for the side neck of the Buchner flask.
[0030] The deformable brush heads are arranged in no less than two groups with the moving strip as the axis of symmetry. Generally, 3-6 groups are arranged. When 3 or 5 groups are arranged, the deformable brush heads are evenly arranged in the circumferential direction with the moving strip as the center. When 4 or 6 groups are arranged, the deformable brush heads are arranged with the moving strip as the axis of symmetry.
[0031] Example 2
[0032] The similarities between this embodiment and embodiment 1 are not described in detail. This embodiment mainly describes the first structure of the tensioner.
[0033] like Figure 2 As shown, the movable strip is a movable rod 32 provided with an external thread, and the tensioner includes a knob 33 and a knob cavity. The knob cavity is arranged in the middle and upper part of the brush handle, and the knob is rotatably arranged in the knob cavity. The knob is provided with an internal thread matching the movable rod, and the movable rod is sleeved in the brush handle cavity and threadedly connected with the knob.
[0034] The knob cavity is arranged at a lower middle position of the brush handle, thereby ensuring that there is enough space at the upper part of the brush handle cavity to place a fine-bristle brush.
[0035] Example 3
[0036] The similarities between this embodiment and embodiment 1 are not described in detail. This embodiment mainly describes the second structure of the tensioner.
[0037] like Figure 3 As shown, the movable strip is a pulling rope 34, and a pulling hole on the brush handle horizontally passes through the brush handle and is connected to the brush handle cavity. One end of the pulling rope is connected to the lower brush body, and the other end passes through the brush handle cavity and the pulling hole in sequence, and extends to the outside of the brush handle. The end of the pulling rope extending to the outside of the brush handle is a tensioner.
[0038] When using the pull rope for tightening, since the pull rope is made of flexible material, the fine-bristle brush can coexist with the pull rope in the brush handle cavity, and the outside of the pull rope acts as a tensioner. After being pulled out to deform the deformed brush head, it can be directly wrapped around the outside of the brush handle to fix the deformation of the deformed brush head.
[0039] Example 4
