Technical Field

[0001] The utility model relates to the technical field of circulation pools, in particular to a bubble elimination device. Background Art

[0002] In a variety of scientific and industrial fields, including electrochemical analysis, biosensing, environmental monitoring, and chemical synthesis, flow cells are key components responsible for introducing liquid samples into the detection system and facilitating effective material exchange between them and the detection electrodes. Traditional flow cell designs typically utilize linear or symmetrical flow paths to ensure stable and even flow of liquid samples across the detection electrode surface, resulting in accurate and reliable measurements.

[0003] However, in practical applications, traditional flow cell designs face a number of challenges. This is particularly true when processing liquid samples containing tiny bubbles. These bubbles can adhere to the electrode surface, interfering with the exchange of substances between the electrode and the liquid, leading to reduced measurement accuracy. Furthermore, the presence of bubbles can affect the flow of the liquid, leading to uneven pressure distribution within the flow channel, further compromising detection stability and repeatability.

[0009] As a preferred technical scheme, the test liquid outlet is arranged on a side wall of the other end of the flow cell.

[0010] As a preferred technical scheme, one end of the flow guide block is an open structure, and the other end of the flow guide block is a sealing structure, and the other end of the flow guide block is arranged corresponding to one end of the test electrode.

[0011] As a preferred technical scheme, the other end of the test electrode passes through the sealing ring and the locking nut in sequence and is arranged outside the flow cell.

[0017] The bubble eliminating device has the following beneficial effects:

[0018] 1) The device has simple structure and convenient operation, can effectively take away small bubbles attached to the surface of the test electrode, and thus significantly improves the accuracy and stability of experimental testing.

[0019] 2) When the test liquid flows from the test liquid inlet port and passes through the port of the flow guide block, the liquid will be forced to flow along the side wall of the flow guide block, especially through the eccentric hole, the direction and speed of the liquid flow will change; due to the special design of the flow guide block, the test liquid forms a dynamic liquid flow pattern in the flow cell; this liquid flow pattern helps to generate shear force and vortex, which can act on the small bubbles attached to the surface of the test electrode, making them separate from the surface of the test electrode and be carried away by the liquid flow; with the continuous flow of the liquid flow, the separated bubbles will be rolled into the main flow and finally discharged from the device through the test liquid outlet; in this way, the bubbles on the surface of the electrode are effectively removed.
