two side walls of the defoaming liquid chamber are connected with a high liquid path partition 12, and a low liquid path b is formed in the space between the high liquid path partition 12 and the bottom of the defoaming liquid chamber;
the low liquid path partition 11 and the high liquid path partition 12 are arranged at intervals to form a switching liquid path c, and the high liquid path a and the low liquid path b are communicated through the switching liquid path c to form a high-low switching liquid path;
the defoaming liquid chamber is provided with a liquid inlet 13 and a liquid outlet 14 corresponding to two ends of the high-low switching liquid path.
In use, liquid (e.g., water) enters the high-low switching liquid path from the liquid inlet 13. The bubbles entrained in the liquid are pushed in the low liquid path b through the upward switching liquid path c to the surface of the high liquid path a, and are contacted with the atmosphere, and then discharged to the atmosphere. Then, the liquid flows down toward the switching liquid path c downward and enters another low liquid path b, and the bubble releasing process is repeated. The size and shape and smooth surface when switching the liquid path design can prevent the violent flowing liquid from interacting and introducing more bubbles. This upward/downward flow is repeated a plurality of times until bubbles in the liquid are eliminated, and in order to better ensure the defoaming effect, the low liquid path partition 11 and the high liquid path partition 12 are at least four groups, and this upward/downward flow is repeated at least four times.
Experimental data show that the defoaming effect is better under the following parameter design: the water flow rate is 33 to 266 ml/min, the cross section size of each switching liquid path c is 12mm multiplied by 7mm, the cross section size of each low liquid path b is 36mm multiplied by 14mm, and the surface roughness of the low liquid path partition 11 and the high liquid path partition 12 is 6 mu m.
The liquid bubble removing device of the present embodiment can remove bubbles (e.g., water) in the liquid very effectively. The liquid bubble removing means may be formed in any desired shape, for example, in the shape of a ring, or may be formed in a linear shape, etc., as long as there are a plurality of high-low switching liquid paths. The upper end or top of the defoaming chamber is open to the atmosphere, allowing the bubbles in the liquid to move to the air/water interface.
Example 2

Liquid enters the measuring liquid chamber 3 from a liquid outlet 14 arranged on the low liquid path b, the liquid flow in the measuring liquid chamber 3 continuously goes upwards over the photoelectric detector of the sensor body 2, and then is discharged outwards through a liquid outlet 5 and is exhausted outwards through an air outlet 4.
The flow-through turbidity sensor of this embodiment may be formed in any desired shape depending on the shape of the antifoam chamber, for example, the shape of the annular body, or may be linear, etc.
When the defoaming liquid chamber is formed in an annular shape, an inner ring of the defoaming liquid chamber may be provided as the measurement liquid chamber. When the defoaming liquid chamber is made into a linear shape, the measuring liquid chamber is communicated with the liquid bubble eliminating device through a liquid outlet.
