Detailed Description

The embodiments of the present invention will be described in detail below, and the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

1-5, a pipette device includes a pipette component; the liquid in the container is aspirated through the pipette component.

The specific construction of the pipette component is as follows:

the pipette component comprises a horizontal pipe part 11 which is horizontally arranged, the horizontal pipe part 11 is communicated with a plurality of vertically arranged absorption pipe parts 12 which are arranged at left and right intervals, the absorption pipe parts 12 comprise vertical pipe parts 121, and liquid inlet ends of the vertical pipe parts 121 are provided with conical pipette parts 122. The vertical pipe portions 121 are provided with first valves 1211, and the first valves 1211 on different vertical pipe portions 121 are opened, so that different vertical pipe portions 121 are selected for liquid suction.

In the actual work process, the size of the conical straw part 122 is designed to be different, so that the conical straw part can be suitable for absorbing solutions with different liquid levels in different containers.

According to conventional designs, the tapered straw portion 122 includes a conically-shaped tapered portion having a liquid inlet at the bottom thereof.

The central portion of the transverse pipe portion 11 is communicated with a connection pipe 2, the connection pipe 2 includes a branch pipe 21 communicated with the transverse pipe portion 11 (in actual operation, a second valve is connected to the branch pipe 21, the branch pipe 21 is communicated with the vertical pipe portion 121 by opening the second valve), and the branch pipe 21 is communicated with a joint pipe 22.

The pipette arrangement further includes a cushion ball member 3 in communication with the mouthpiece 22; specifically, the cushion ball member 3 includes a cushion ball 32 (inside the cushion ball 32), a joint tube 31 that fits to the joint tube 22 is communicated with the bottom of the cushion ball 32, and the joint tube 31 is inserted into the joint tube 22.

The top of the buffer ball 32 is communicated with a pipette 33 (the pipette 33 is provided with scale marks), and the pipette 33 is inserted with a suction ball part. Negative pressure is formed through the ear sucking ball part, and then the solution in the container is absorbed.

The specific structure of the suction ear ball component is as follows:

the suction bulb part comprises a suction bulb 41, and the bottom of the suction bulb 41 is communicated with a suction head pipe 42 inserted with the pipette 33. The interior of the ear suction bulb 41 is hollow, and the ear suction bulb 41 is made of rubber; the pipette 33 is made of glass.
