Description

Technical Field

[0001] This utility model relates to the field of stirring technology, and in particular to an electric stirrer for laboratory use. Background Technology

[0002] In the research and development process of biomedicine and other fields, experiments are often required. In laboratory experiments, various chemical substances are usually reacted. After different chemical substances are added, these mixtures need to be poured into a stirring device for stirring to ensure that they are fully mixed and reacted. After stirring, the stirring device needs to be cleaned frequently. However, the cleaning of the stirring device often requires technicians to perform the cleaning. There may be cases where the cleaning is not thorough or forgotten, which may lead to incorrect experimental data. In addition, there are problems such as low cleaning efficiency and wasting technicians' time. Utility Model Content

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0005] An experimental electric stirrer includes a body, a telescopic device rotatably connected to the body, a connecting plate on the telescopic device, a stirring rod rotatably connected to the connecting plate, a cleaning cabinet on the body, and a spray head on the cleaning cabinet.

[0006] Furthermore, the machine body is provided with a rotating shaft, which is rotatably connected to the machine body. The machine body is provided with a first motor, which is connected to a first synchronous pulley. The rotating shaft is connected to a second synchronous pulley, which is connected to the first synchronous pulley and the second synchronous pulley by a synchronous belt. The telescopic device is connected to the rotating shaft.

[0007] Furthermore, the body is provided with heat dissipation holes.

[0008] Furthermore, the connecting plate is equipped with a stirring motor, and the output end of the stirring motor is connected to the stirring rod.

[0009] Furthermore, a stirring head is provided at the lower end of the stirring rod.

[0010] Furthermore, the cleaning cabinet is also equipped with an air knife.

[0011] Furthermore, the machine body is equipped with a waste liquid collection tank, which is located below the cleaning cabinet and is connected to the waste liquid collection tank.

[0012] Furthermore, the machine body is provided with a positioning block, and the positioning block is provided with a strip-shaped hole.

[0013] Furthermore, the waste liquid collection box is equipped with a handle.

[0014] Furthermore, the outlets of the spray head and the air knife are tilted downwards.

[0015] The beneficial effects of this utility model are as follows: Stirring is achieved by rotating the stirring rod, and the stirring is continuously raised and lowered by the telescopic device, improving stirring efficiency. After stirring is complete, rotating the telescopic device moves the stirring rod to the top of the cleaning cabinet, and lowering the telescopic device allows the stirring rod to extend into the cleaning cabinet. The stirring rod is then cleaned by spraying water from the spray head. During this process, rotating the stirring rod ensures more thorough cleaning, and raising the telescopic device moves the stirring rod upwards for cleaning, improving cleaning efficiency and achieving automatic stirring. Simultaneously, the stirring rod is automatically cleaned, increasing efficiency and avoiding the impact on experimental data caused by omissions during manual cleaning. Attached Figure Description

The upper cover 3 is detachably connected to the lower frame 2 for easy installation and maintenance. The body 1 contains a power supply, a control circuit board, a water tank, a water pump, and an air pump. The front of the body 1 has a start button 4 and a stop button 5 for starting and stopping. A telescopic device 6 is rotatably connected to the body 1. The telescopic device 6 can rotate on the body 1 and can extend and retract during operation. The device 6 can be a pneumatic cylinder, hydraulic cylinder, or electric cylinder, etc. A connecting plate 7 is provided on the telescopic device 6, which can extend and retract the connecting plate 7. A stirring rod 8 is rotatably connected to the connecting plate 7, and the stirring rod 8 rotates to stir the mixture in the liquid container 25 evenly. A cleaning cabinet 9 is provided on the machine body 1, which can be located on the left side of the telescopic device 6. A spray head 10 is provided inside the cleaning cabinet 9, and the spray head 10 is connected to a water tank via a water pump. Water is supplied from the water tank and sprays from the spray head 10. High-pressure water is sprayed to clean the stirring rod 8. During operation, the liquid container 25 is first placed at the designated position on the machine body 1. The start button 4 is pressed to drive the stirring rod 8 to rotate. The telescopic device 6 descends, causing the stirring rod 8 to descend deeper into the liquid container 25 for stirring. During this process, the telescopic device 6 can be continuously driven to rise and fall, improving stirring efficiency. After stirring is complete, the stirring rod 8 stops rotating, and the telescopic device 6 rises, causing the stirring rod 8 to detach from the liquid container 25. The telescopic device 6 is rotated clockwise, moving the stirring rod 8 above the cleaning cabinet 9. The telescopic device 6 is then driven to descend, allowing the stirring rod 8 to extend into the cleaning cabinet 9. The water pump is started to pump water from the water tank into the spray nozzle 10 to clean the stirring rod 8. During this process, rotating the stirring rod 8 ensures more thorough cleaning, and the telescopic device 6 rises, causing the stirring rod 8 to move upwards for cleaning, improving cleaning efficiency. This application can achieve automatic stirring and automatic cleaning of the stirring rod 8, improving efficiency and avoiding the impact on experimental data caused by omissions in manual cleaning.
