As shown in fig. 1 to 3, in some embodiments of the present invention, a defoaming device has a first direction 01 and includes: the device comprises a body 1, wherein at least one chamber 11 is arranged in the body, the chamber 11 is provided with a first port 111 and a second port 112 which are communicated, the first port 111 and the second port 112 are both oriented to the same side of the first direction 01 and are communicated with the environment outside the body 1, and the chamber 11 is used for accommodating liquid; wherein the caliber of the second port 112 is smaller than that of the first port 111, and the portion of the chamber 11 near the second port 112 is horn-shaped and gradually shrinks along the direction near the second port 112. Specifically, referring to fig. 3, liquid enters the first chamber 11 through the liquid inlet 2, flows to the bottom of the chamber 11, and gradually increases in the first direction 01 as the volume of the liquid increases; since the cross-section of the trumpet-like configuration near the second port 112 tapers in a direction vertically upward along the first direction 01 such that the flow velocity of the flowing liquid increases continuously before reaching the interface between the liquid and air via the second port 112, such an increasing acceleration in a vertical upward direction along the first direction 01 can continuously push bubbles entrained in the fluid to the interface between the liquid and air until the bubbles break at the interface and release the gas to the atmosphere, thereby achieving a defoaming effect for the liquid.
As shown in fig. 1 to 4, in some embodiments of the present invention, the chamber 11 includes a plurality of chambers; as shown in fig. 3, the chambers 11 are arranged one by one, and the second port 112 of one of the chambers 11 communicates with the first port 111 of the other chamber 11 on the same side in the first direction 01. Specifically, as the liquid level in the first chamber 11 increases, the liquid flowing upward through the second port 112 of the first chamber 11 will enter the second chamber 11 through the first port 111 of the second chamber 11 in communication with the first chamber 11, and the above-mentioned "flow rate increase" is performed through the second port of the second chamber 11, thereby forcing the bubbles to move to the gas-liquid interface and collapse to be discharged to the atmosphere "; because the plurality of chambers 11 are arranged, the defoaming process can be repeated for a plurality of times, and bubbles mixed in the liquid can be further discharged, so that the defoaming effect of the defoaming device provided by the invention is better and more thorough.
