[0031] See Figure 1The cleaning brush for the separatory funnel in this embodiment includes: a brush rod 100, a sleeve 200, a support rod 300, and a bristle fixing rod 400. The brush rod 100 is a rod-shaped structure with a handle at the top. The sleeve 200 is a hollow tubular structure that is sleeved on the outside of the brush rod 100 and slidably connected along the length of the brush rod 100. The bristle fixing rod 400 is a plate-shaped structure with one end rotatably connected to the bottom end of the brush rod 100 along its length. The bristle fixing rod 400 has a slide rail on one side near the brush rod and bristles 410 on the other side. The support rod 300 is a rod-shaped structure with one end rotating and the other end sliding along its length. The rotating end of the support rod 300 is rotatably connected to the outside of the sleeve 200, and the sliding end of the support rod 300 is slidably connected to the slide rail of the bristle fixing rod 400.
[0032] In this embodiment, a convenient tool is provided for cleaning separatory funnels, reagent bottles, and other laboratory instruments with narrow openings and wide interiors. This test tube brush is easy to operate; it can be inserted into the separatory funnel from the top, and the bristles 410 can be unfolded. The opening angle of the bristles 410 can be adjusted according to the width of the container's inner wall, allowing the bristles 410 to adhere to the inner wall of the instrument, effectively removing dirt and ensuring a cleaner cleaning of the separatory funnel's inner wall, preventing cross-contamination between samples. Specifically, the unopened test tube brush is inserted into a container with cleaning fluid, and the sleeve 200 fitted outside the brush rod 100 is pushed to open the bristle fixing rod 400 with bristles 410, allowing it to adhere to the inner wall of the pear-shaped funnel for better cleaning of the container's inner wall.
[0033] In one specific embodiment, there are two or more support rods 300 and bristle fixing rods 400, and the number of support rods 300 corresponds one-to-one with the number of bristle fixing rods 400. The two or more bristle fixing rods 400 are spaced apart along the circumferential direction of the movable ring 500.
[0034] Specifically, in this embodiment, there are four bristle fixing rods 400, with an angle of 90 degrees between any two adjacent bristle fixing rods 400. When all four bristle fixing rods 400 are opened simultaneously, they can be rotated circumferentially along the brush rod 100, allowing the bristles 410 on the bristle fixing rods 400 to clean the inner wall of the container. By increasing the number of bristle fixing rods 400, the number of bristles 410 is increased, thereby improving the cleanliness and efficiency of cleaning the inner wall of the container.
[0035] In one specific embodiment, it further includes a movable ring 500, which is disposed at the end of the brush rod 100 to facilitate rotatable connection with the bristle fixing rod 400.
[0036] The four bristle fixing rods and support rods 300 have the same structure.
[0037] In one specific embodiment, it further includes: a fixing knob 700, one end of which is a rod-shaped structure with external threads, and the other end is a cross-shaped structure. The end of the fixing knob 700 with external threads passes through the sleeve 200 and is detachably connected to the brush rod 100. The sleeve 200 and the brush rod 100 can be fixed by using the fixing knob 700.
[0038] Specifically, the end of the brush rod 100 furthest from the sliding ring is the grip end, which has a handle. The handle is vertically aligned with the brush rod 100 and in the same straight line direction for easy gripping. A first mounting hole is formed at the grip end of the brush rod 100 along its length perpendicular to the brush rod 100. A second mounting hole is formed on the sleeve 200 near the grip end of the brush rod 100. A fixing knob 700 passes through the second mounting hole and the first mounting hole in sequence to fix the sleeve 200 and the brush rod 100. Thus, after inserting the test tube brush into the container, the bristle fixing rod 400 is opened at a certain angle. After aligning the first and second mounting holes, the fixing knob is inserted for fixation. At this point, only the grip end at the handle end needs to be rotated.
[0039] In one specific embodiment, the rotation angle of the bristle fixing rod 400 relative to the movable switch is in the range of 0-50 degrees.
[0040] In one specific embodiment, the length of the sleeve 200 is within the range of 1 / 2 to 3 / 5 of the length of the brush rod 100.
[0041] In one specific embodiment, the length of the brush handle 100 is 35cm.
[0042] In one specific embodiment, the brush handle 100 has a diameter of 1 cm.
[0043] In one specific embodiment, the length of the bristles 410 is 4 mm.
[0044] In one specific embodiment, the sleeve 200 is 20cm long.
[0045] In one specific embodiment, the brush rod 100, sleeve 200, support rod 300, and movable ring 500 are made of polytetrafluoroethylene; the bristle fixing rod 400 is made of polyethylene; and the bristles are made of nylon.
