Description

Technical Field

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

[0002] In laboratories in the fields of chemistry, biology, and medicine, pipettes are commonly used as experimental tools, and their accuracy and cleanliness have a crucial impact on the reliability of experimental results. However, traditional pipette cleaning methods mostly use manual operations, which is not only inefficient, but also easily causes pipettes to collide with each other during the cleaning process, resulting in damage or contamination of the pipettes, which in turn affects the accuracy of the experimental results. Therefore, the development of a cleaning device that can clean multiple pipettes at one time while avoiding collisions has important practical significance and application value.

[0003] At present, there are some pipette cleaning equipment on the market, such as bottle washing machines, pipette cleaning machines, etc. These devices have improved the cleaning efficiency of pipettes to a certain extent, but there are still some problems. For example, although the bottle washing machine can clean multiple pipettes at the same time, it cannot completely avoid collisions between pipettes due to the limitations of its internal structure; and although the pipette cleaning machine can avoid collisions between pipettes, it can usually only clean one pipette at a time, and the efficiency is low.

[0004] Although some cleaning equipment uses ultrasonic cleaning, which can improve the cleaning efficiency to a certain extent, there is still a phenomenon that multiple pipettes collide with each other and become damaged during the simultaneous cleaning. Utility Model Content

[0005] In order to solve the above problems, an embodiment of the utility model provides a cleaning device that can simultaneously clean multiple pipettes without causing collisions between them.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a pipette cleaning device, including a base, a cleaning tank is arranged in the base, a cleaning bracket for placing the pipette is arranged in the cleaning tank, and positioning devices for fixing the cleaning bracket are arranged on both sides of the cleaning tank.

[0007] As a further improvement of the above technical solution:

[0008] The cleaning bracket comprises a shell, a positioning partition is arranged in the shell, and a water inlet hole is arranged on the side wall of the shell.

[0009] There are multiple positioning baffles which are evenly distributed along the height direction of the shell, and each positioning baffle is provided with a through hole for passing the pipette.

[0010] The positioning device comprises fixing plates symmetrically installed in the cleaning tank, and the side walls on the opposite sides of the two fixing plates are provided with fixing grooves for fixing the end of the shell.

[0011] The card slot is a U-shaped slot, and the opening increases gradually from bottom to top.

[0012] The thickness of the fixing plate gradually decreases from bottom to top.

[0013] Both ends of the shell are provided with covers used in conjunction with the card slots, one side of the cover is provided with a plug-in sleeve connected to the shell, and a card-connecting boss is provided on the side wall of the plug-in sleeve.

[0014] The beneficial effects of the embodiments of the utility model are as follows: 1. The cleaning device of the pipette comprises a base, a cleaning tank is arranged in the base, a cleaning bracket for placing the pipette is arranged in the cleaning tank, the design of the cleaning bracket can perform a single synchronous cleaning of multiple pipettes, and can avoid the phenomenon of mutual collision between the pipettes, positioning devices for fixing the cleaning bracket are arranged on both sides of the cleaning tank, and the design of the positioning device can place multiple cleaning brackets while fixing the positioning bracket, so that more pipettes can be cleaned at one time.

[0015] 2. Both ends of the shell are provided with sealing covers used in conjunction with the card slot. The function of the sealing cover is to replace the shell to bear the force when it is fixed to avoid damage to the shell during use. One side of the sealing cover is provided with a plug-in sleeve connected to the shell, and a card-connecting boss is provided on the side wall of the plug-in sleeve. The end of the plug-in sleeve is plugged into the shell, and the card-connecting boss abuts against the top of the shell. The length of the shell is less than the length of the pipette. The plug-in sleeve plays a sealing role at both ends of the shell and can also protect the end of the pipette. The advantage of this design is that it is convenient to place multiple pipettes in the shell, which is convenient for taking and fixing the pipette. BRIEF DESCRIPTION OF THE DRAWINGS
