Description

Aeration module

The invention relates to an aeration module, in particular to an aeration module which has a gas-liquid mixing function and can be applied to purify water.

The conventional aerator is mainly composed of a pump, an outlet pipe connecting the pump, and a gas-liquid mixing pipe connecting the outlet pipe. The outlet pipe diameter is gradually tapered from the pump to the gas-liquid mixing pipe. The gas-liquid mixing pipe comprises a pipe connecting the outlet pipe and an air inlet pipe connecting the outside air, and the pipe has a larger diameter than the outlet pipe. When the pump draws water out and pressurizes it to the junction of the outlet pipe and the conduit, the water flow will create a negative pressure after entering the conduit. This phenomenon is called the Venturi tube principle. At the same time, the negative pressure will cause the outside air to be sucked into the gas-liquid mixing pipe from the intake pipe, and mixed with the water flow to form a bubble, and after the mixed bubble water flow is directed to the sewage, the purpose of aeration can be achieved.

However, when the water flow of the conventional aerator structure flows through the gas-liquid mixing tube, the bubble volume is determined by the volume of the intake pipe and the water pressure of the pump. In addition, the pump water pressure must maintain the water flow to a specific flow rate above which the air can be drawn in. Therefore, if the user can lift the gas before the flow rate can be arbitrarily reduced, the average volume of bubbles generated in the gas-liquid mixing tube cannot be changed. If the user needs finer bubbles for water purification, the conventional aerator cannot meet the demand. .

Therefore, the second stop section 222 can abut against the first stop section 142 after the connecting rod 22 is completely inserted into the connecting groove 14 .

The manner of use and the principle of operation of the present invention are described below. Referring to FIG. 4-1, the present invention is combined with the connecting groove 14 by the connecting rod 22, so that the mixing device 10 and the flow guiding device 20 are integrated into one body and passed through a pump (not shown). The high-pressure water flow is input from the second passage 23, and after entering the chamber 13 through the first passage 121, the outside of the aeration module 100 is discharged from each of the aeration holes 111. When the connecting rod 22 is coupled with the connecting groove 14, since the diameter of the first passage 121 is slightly larger than the neck of the second passage 23, a venturi configuration is formed with the second passage 23. In this embodiment, the connecting groove 14 is provided with an external thread 221a on the inner surface of the first pressing portion 141, and the outer surface of the second pressing portion 221 is provided with a corresponding internal thread 141a. The first pressing section 141 and the second pressing section 221 form a complete or partial close connection. The term "closely connected" as used in the present invention means watertight and pneumatically closed so that water or air (normal or pressurized air) cannot escape from the gap between the first pressing section 141 and the second pressing section 221. Out. In the embodiment, the connecting groove 14 is disposed at an end of the first pressing portion 141 away from the outer casing 12, and the connecting rod 22 includes a ring disposed on the second pressing portion 221 adjacent to the second portion. The stop section 222 has an end and a tension ring 223 that should accommodate the area 144 to prevent water or air from leaking between the first pressing section 141 and the second pressing section 221 .

Thereby, when the water flows through the venturi formed by the first passage 121 and the second passage 23, a disturbance zone 40 is generated in the first passage 121 due to the water pressure imbalance, and the disturbance zone 40 is specifically A negative pressure is formed near the wall surface of the first passage 121, and the air outside the connecting groove 14 is sucked into the clearance 90 through the intake passage 143 by the suction force, and is mixed with water to generate a water flow containing bubbles.

The user can adjust the degree of close connection between the first pressing section 141 and the second pressing section 221, as shown in FIG. 5-1 and FIG. 5-2, so that the first stopping section 142 and the The distance between the second stop segments 222 is increased by 50, and the associated volume increases the volume of the clearance 90 between the first passage 121 and the second passage 23. The volume of the clearance 90 affects the flow rate of air taken in from the intake passage 143 and increases the average volume of bubbles generated after the gas-liquid mixing. Therefore, the user can adjust the degree of close connection between the first pressing section 141 and the second pressing section 221 to achieve the effect of freely adjusting the size of the aeration bubble.

When the high pressure water flow is passed, the tight connection of the first pressing section 141 and the second pressing section 221 may be loosened to change the volume of the clearance 90. Therefore, the mixing device 10 includes a locking member 18 that is disposed on the first stopping portion 142 and locks the second stopping portion 222.
