[0036] The utility model discloses a bubbler with automatic adaptive flow adjustment. One end of a main body 1 is a water inlet 2, and the other end of the main body 1 is a water outlet 3. A flow limiting block 4 is arranged in the end of the main body 1 close to the water inlet 2. The lower end of the flow limiting block 4 is clamped and fixed by a fixing block 18. The fixing block 18 and the inner wall of the main body 1 can be fitted by interference. The upper end of the flow limiting block 4 is in limited contact with a second limiting step 15. A flow limiting sheet 5 is arranged in the flow limiting block 4. A flow limiting sheet 5 is arranged in the flow limiting sheet 5. A limiting hole 6 is provided on the limiting block 4, a limiting insert 7 is provided on the upper part of the limiting block 4, a spring 9 is provided on the upper part of the limiting insert 7, the upper end of the spring is in contact with the first limiting step 14, under the elastic force of the spring 9, the limiting insert 7 is pushed downward on the limiting block 4, wherein the lower part of the limiting insert 7 is provided with more than one protruding limiting boss 8, the number and position of the limiting boss 8 and the limiting hole 6 correspond, when the limiting insert 7 contacts the limiting block 4, the limiting boss 8 is inserted 9, and the vent 24 is vented to the bottom of the main body 1. When the gas-liquid mixture is injected into the water channel 11 of the water limiting insert 7, the gas-liquid mixture will enter the flow limiting hole 6, and a small water flow gap is formed between the two. When the air or oxygen and water in the water purification equipment enter the main body 1 through the water inlet 2, when the flow rate of the gas-liquid mixture is low, the gas-liquid mixture passes through the water flow gap. Under the elastic force of the spring 9, the low-flow-rate gas-liquid mixer cannot push the flow limiting insert 7. When the flow rate of the gas-liquid mixture is fast and the water pressure is high, the gas-liquid mixture passes through the water flow gap, and its high water pressure can overcome the elastic force of the spring 9 to push the flow limiting insert 7 upward. Since the flow limiting hole 6 and the flow limiting boss 8 are conical structures, when the flow limiting insert 7 and the flow limiting boss 8 move upward, the size of the water flow gap gradually increases, so that the gas-liquid mixture can pass through the flow limiting hole 6 smoothly, so that the pressure on both sides of the flow limiting hole 6 is balanced, and when the gas-liquid mixture passes through the water flow channel 11 of the flow limiting insert 7, the gas in the gas-liquid mixture precipitates out from the water, thereby forming bubble water, and finally the bubble water is output through the water outlet 3. The present invention provides a bubbler with automatic adaptive flow adjustment. When the gas-liquid mixture passes through the flow limiting hole 6 via the water inlet 2, when the flow is small, the flow limiting insert 7 and the flow limiting boss 8 move downward, and the water flow gap between the flow limiting boss 8 and the flow limiting hole 6 is small. When the flow is large, the water pressure overcomes the elastic force of the spring 9 and pushes the flow limiting insert 7 and the flow limiting boss 8 upward, so that the water flow gap between the flow limiting boss 8 and the flow limiting hole 6 gradually becomes larger. The water flow gap changes according to the size of the flow, and can adapt to different flow rates and water pressures, with good versatility.
