Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a pipette cleaning device. Background Art

[0002] A pipette is a laboratory tool for accurately dispensing and transferring liquids. It usually consists of a handheld pipette and a pipette tip, which can absorb and release liquids through pressure difference. Pipettes are widely used in experiments in biochemistry, molecular biology, clinical diagnosis and other fields for preparing samples, preparing reagents, conducting reactions and other operations. They provide precise volume control, allowing experimenters to accurately transfer trace to large amounts of liquid in experiments. Since it is a micropipette, its internal space is cleaned using an external cleaning tool, which will bring a lot of cleaning difficulties, is not conducive to repeated use, and cause waste. If it is not cleaned thoroughly, it may cause mixing of different liquid components in the same pipette, causing errors in the experiment. During the cleaning process of the existing pipette, due to the different sizes of the pipette, the pipette may be offset when it is fixed, resulting in the inability to stably clean the pipette, thereby affecting work efficiency; therefore, we propose a pipette cleaning device to solve the above-mentioned problems. Utility Model Content

[0005] Preferably, after the pipette body is fixed, according to the position height of the pipette body, the second arc-shaped telescopic sleeve is driven by the cylinder to move downward along the second arc-shaped telescopic column until the brush enters the pipette body, and then the special cleaning solution is poured into the water supply tank through the water inlet pipe, and then driven by the water pump, the special cleaning solution enters the second water outlet pipe through the water supply tank for spraying, thereby cleaning the inner and outer walls of the pipette body. In this process, the brush is inside the pipette body, and the rotating column drives the brush to rotate through the drive of the motor, and the inner wall of the pipette is further cleaned to avoid the inner wall of the pipette being not cleaned cleanly, resulting in a mixture of different liquid components when the same pipette is used again, which brings errors to subsequent experiments.

During the cleaning process, the water that has cleaned the pipette body flows out through the water outlet hole along the annular groove, and the arc-shaped columns firmly support the operating table. When one group of pipette bodies is cleaned, the circular base rotates along the circular groove through the drive of the rotating driver, which facilitates the cleaning of the next group of pipette bodies.

When the pipette body is fixed, according to the position height of the pipette body, the second arc-shaped telescopic sleeve is driven by the cylinder to move downward along the second arc-shaped telescopic column until the brush enters the pipette body, thereby improving the flexibility of the cleaning device.

[0012] Beneficial effects of the utility model:

[0013] 1. According to the previous situation that during the cleaning process of the pipette, due to the different sizes of the pipette, the pipette may be offset when it is fixed, resulting in the inability to stably clean the pipette, thereby affecting the work efficiency.

[0014] 2. After the pipette body is fixed, according to the position height of the pipette body, the second arc-shaped telescopic sleeve is driven by the cylinder to move downward along the second arc-shaped telescopic column until the brush enters the pipette body, and then the special cleaning solution is poured into the water supply tank through the water inlet pipe, and then driven by the water pump, the special cleaning solution enters the second water outlet pipe through the water supply tank for spraying, thereby cleaning the inner and outer walls of the pipette body. In this process, the brush is inside the pipette body, and the rotating column drives the brush to rotate through the drive of the motor, and the inner wall of the pipette is further cleaned to avoid the inner wall of the pipette not being cleaned cleanly, resulting in the mixing of different liquid components inside the same pipette when it is used again, which brings errors to subsequent experiments.
