example 1

[0034] Example 1: Introduction to component types and functions

[0035] The interface component consists of three parts:

[0036] Container (1): including container shell, container ring switch, container control knob, container fixing frame. Wherein the ring switch of the container is threadedly connected with the control knob of the container.

[0037] Sample (2): including the sample housing, the sample spherical switch, the sample control knob, and the sample concave piston.

[0038] Resetting part (3): including the reset part housing and the convex piston of the reset part.

[0039] When taking and sending samples, the container (1) is joined with the sample (2). It is fixed by a convex key and a card slot, and the ring switch of the container is combined with the spherical switch of the sample. The interface can be seamlessly docked and remains airtight when in use.

[0040] In order to avoid the impact of impurities or residual fluid on the follow-up work, the sa...

[0051] Example 3: Sample delivery operation

[0052] 1. Adjust the posture, turn the ring switch of the container to off, and turn the spherical switch of the sample to the concave shape to close. (Such as Figure 6 of 7)

[0053] 2. Connect and fix the interface between the container (1) and the sample (2). (Such as Figure 6 6 of

[0054] 3. Turn the ring switch of the container to open. (Such as Figure 6 of 5)

[0055] 4. Turn the sample ball switch to ON. (Such as Figure 6 of 4)

[0056] 5. Press the concave piston of the sample to send the sample. (Such as Figure 6 of 3)

[0057] 6. Turn the ring switch of the container to off. (Such as Figure 6 2) of

[0058] 7. Separate interface. (Such as Figure 6 1) of

Abstract

The invention belongs to the technical field of fluid interfaces. By utilizing a simple mechanical principle, a simple, quick, cheap and reusable fluid closed sample taking and sending interface assembly is designed. The fluid sample taking and sending closed interface assembly includes a containing piece (1), a sample piece (2) and a reset piece (3). The annular switch and the spherical switch are combined, so that the interface is seamlessly connected. Actions such as sealing, sampling and sample sending can be completed by utilizing different combination forms. The reset assembly is used for resetting. According to the invention, complicated fluid sealed sample taking and sending work is completed by a simple mechanical assembly, and repeated and continuous operation can be achieved; the sample taking and sending operation is simpler and quicker; basic requirements of teaching and basic experiments are met; the corresponding working efficiency is improved, and the cost is reduced.

Description

technical field [0001] Technical field of fluid interface. Background technique [0002] During the application, processing, and experiments related to fluids in a closed environment, sampling, sample delivery, and feeding processes are often involved. This process requires no impurities to enter and exit, so specific devices, interfaces, etc. will be required to carry out. [0003] Existing products are either complex and expensive, such as the need to create vacuum conditions; or the entire system cannot be used repeatedly and continuously before reset, such as pre-adding or post-recovery; or cannot be completely sealed, resulting in impurities or samples Overflow; or single function, can only take samples, only send samples, or must take and send phase cycles. [0004] Therefore, there is a need for an interface assembly that uses simple mechanical principles to design simple parts and operation methods, and meets the requirement of repeatedly taking and sending fluid s...
