A spring 14 is set on the other side of the flow limiting insert 9, one end of the spring 14 is in contact with the flow limiting insert 9, and the other end of the spring 14 is limitedly matched with the inner wall of the water outlet joint 7.

[0026] Furthermore, the steady flow filter 4 includes a filter body 21, a filter hole 22 is opened on the filter body 21, a baffle 23 is formed at one end of the filter body 21, an opening 24 is formed at the other end of the filter body 21, and a retaining ring 25 is formed on the outer wall of the opening 24, and the outer wall of the retaining ring 25 is sealed with the inner wall of the main body 1.

[0027] Furthermore, the opening 24 of the flow stabilizing filter 4 faces the side of the water inlet joint 5, or the opening 24 of the flow stabilizing filter 4 faces the side of the water outlet joint 7. When the opening 24 of the flow stabilizing filter 4 faces the side of the water inlet joint 5, when the gas-liquid mixture delivered from the water purification equipment enters the flow stabilizing chamber 3 through the water inlet pipe 6 and the water inlet joint 5, the gas-liquid mixture first enters the inside of the flow stabilizing filter 4 from the opening 24, and due to the obstruction of the baffle 23, the gas-liquid mixture flows to the surroundings of the flow stabilizing filter 4 through the filter hole 22, and finally flows into the water outlet joint 7 (such as the attached Figure 1 As shown in the figure, when the opening 24 of the flow stabilizing filter 4 is arranged toward the side of the water outlet joint 7, the gas-liquid mixture delivered from the water inlet pipe 6 and the water inlet joint 5 enters the flow stabilizing chamber 3, and is first blocked by the baffle 23, and then flows around the baffle 23, and then enters the flow stabilizing filter 4 through the filter hole 22, and finally flows into the water outlet joint 7 from the opening 24 of the flow stabilizing filter 4 (as shown in the figure). Figure 2 As shown), by setting the flow stabilizing filter 4 in the forward or reverse direction, the flow direction of the gas-liquid mixture entering the flow stabilizing chamber 3 can be changed.

[0028] Furthermore, the outer wall of the retaining ring 25 is formed with a sealing groove 26, and a sealing ring 27 is arranged in the sealing groove 26, and the sealing ring 27 is sealed with the inner wall of the main body 1. The sealing ring 27 is arranged in the retaining ring 25 to improve the sealing between the retaining ring 25 and the inner wall of the main body 1, and prevent water from flowing through the gap between the retaining ring 25 and the main body 1.

[0029] Furthermore, the main body 1 and the cover shell 2 are connected via threads, so that the main body 1 and the cover shell 2 are easy to install and disassemble.

The flow limiting hole 11 can be made into a conical structure or a triangular cone or a square cone or a polygonal cone structure, and the flow limiting convex column 13 can also be made into a corresponding conical structure or a triangular cone or a square cone or a polygonal cone structure, or the flow limiting convex column 13 can also be made into a cylindrical structure or a triangular column or a square column or a polygonal column structure.

[0031] Further, the water flow channel 12 is arranged in the flow limiting insert 9, or the water flow channel 12 is arranged on the outer wall around the flow limiting insert 9. A hole can be directly opened in the flow limiting insert 9 to form the water flow channel 12, or a groove can be opened around the flow limiting insert 9 to form the water flow channel 12 between the groove and the inner wall of the water outlet joint 7, or the outer diameter of the flow limiting insert 9 can be directly reduced to form the water flow channel 12 between the flow limiting insert 9 and the water outlet joint 7.

[0032] Furthermore, a protruding positioning column 31 is formed on the upper part of the current limiting insert 9, and a convex rib 32 is formed on the outer wall of the positioning column 31. The positioning column 31 is cylindrical, prismatic or square, and the lower part of the spring 14 is sleeved on the outer wall of the positioning column 31. The positioning column 31 plays a positioning role for the spring 14, and the convex rib 32 makes the spring 14 and the positioning column 31 clamped reliably to prevent the positioning column 31 from being disengaged due to excessive water pressure.

[0033] Furthermore, a limiting step 33 is formed in the water outlet joint 7, a first filter screen 34 is arranged between one end of the spring 14 and the limiting step 33, a second filter screen 35 and a fixing block 36 are arranged in the water outlet joint 7 near one end of the flow-limiting block 8 at the steady flow chamber 3, and the fixing block 36 is fixed to the inner wall of the water outlet joint 7. The first filter screen 34 and the second filter screen 35 can filter the bubble water passing through, and the mesh in the filter screen can further divide the bubbles, so that the bubbles passing through become smaller and denser small bubbles.

[0034] Furthermore, the fixing block 36 is in a circular ring shape, or an inner convex ring 37 is formed on the inner wall of the circular ring-shaped fixing block 36 .

[0035] The utility model discloses a bubbler with a flow stabilizing structure. The high-pressure gas-liquid mixture delivered by the water purification equipment enters the flow stabilizing chamber 3 formed between the main body 1 and the cover shell 2 through the water inlet pipe 6 and the water inlet joint 5. The internal space of the flow stabilizing chamber 3 is increased, so that the flow velocity of the high-pressure gas-liquid mixture is reduced and the pressure is reduced, so as to achieve the effect of flow stabilization and pressure stabilization. In addition, the water flows through the filter holes 22 of the flow stabilizing filter 4, and the filter holes 22 cut the water flow to reduce the fluctuation of the outlet water type, and cut the large bubbles in the gas-liquid mixture into small bubbles. Then the gas-liquid mixture is delivered to the water outlet joint 7. If the flow velocity of the gas-liquid mixture is low, the gas-liquid mixture passes through the water flow gap between the flow limiting convex column 13 and the flow limiting hole 11, and the spring 14 elastic force is applied to the gas-liquid mixture. Under the action, the gas-liquid mixer with a low flow rate cannot push the flow limiting insert 9. When the gas-liquid mixture still has a fast flow rate and a high water pressure, the gas-liquid mixture passes through the water flow gap, and its high water pressure can overcome the elastic force of the spring 14 and push the flow limiting insert 9 to move to the left. Since the flow limiting hole 11 and the flow limiting boss 13 are conical structures, when the flow limiting insert 9 and the flow limiting boss 13 are pushed to the left, the size of the water flow gap gradually increases, so that the gas-liquid mixture can smoothly pass through the flow limiting hole 11, so that the pressure on both sides of the flow limiting hole 11 is balanced, and when the gas-liquid mixture passes through the water flow channel 12 of the flow limiting insert 9, the gas in the gas-liquid mixture precipitates from the water to form bubble water, and finally the bubble water is output through the water outlet joint 7. The present invention provides a bubbler with a flow stabilizing structure. First, a flow stabilizing structure is added to the bubbler, so that the high-pressure gas-liquid mixture delivered by the water purification equipment can reach a stable flow velocity and water pressure in the flow stabilizing chamber 3 formed between the main body 1 and the cover 2, and the water flow fluctuation is small, so that the bubbler has a better bubble effect; second, a flow stabilizing filter 4 is arranged in the flow stabilizing chamber 3, and the filter holes 22 in the flow stabilizing filter 4 can cut the gas-liquid mixture to further reduce the fluctuation of the water flow; third, the gas-liquid mixture passes through the flow limiting hole 1 1, when the flow rate is small, under the push of the spring 14, the flow limiting insert 9 and the flow limiting boss 13 move to the right, and the water flow gap between the flow limiting boss 13 and the flow limiting hole 11 is small. When the flow rate is large, the gas-liquid mixed hydraulic pressure overcomes the elastic force of the spring 14 and pushes the flow limiting insert 9 and the flow limiting boss 13 to move to the left, so that the water flow gap between the flow limiting boss 13 and the flow limiting hole 11 gradually becomes larger. According to the size of the flow rate, the water flow gap also changes accordingly, which can adapt to different flow rates and water pressures and has good versatility.
