In an embodiment of the water-air mixing device of the present utility model, please refer to fig. 1-3; the water-gas mixing device comprises a spiral output pressurizing pump device, a water supply device, a gas pressurizing device and an output pipe. The screw output pressurizing pump device includes a centrifugal pump 100, a mixing tube 200, and a screw shaft 300. The centrifugal pump 100 includes a pump body 110, a centrifugal impeller (not shown), and a pump cover 120, the pump cover 120 being assembled to the pump body 110, the pump cover 120 having an input port 121 and an output port 122. Wherein the mixing tube 200 is integrally formed at the output port 122. Specifically, the mixing tube 200 is integrally injection molded or die-cast with the pump cap 120. The outside of the mixing pipe 200 is provided with a connecting part 201, the connecting part 201 is connected with a water pipe, and after the water flow is output from the mixing pipe 200, the water flow is driven into the water pipe, and the water flow is output by the water pipe. Specifically, the connection portion 201 is an external thread provided on the outer side surface of the mixing tube 200, and the external thread is connected with the connector of the water pipe, so as to increase stability. The mixing tube 200 has a flow passage therein, which communicates with the output port 122 of the centrifugal pump 100. Since the outer diameter of the screw shaft 300 is equal to the inner diameter of the flow channel, the outer sidewall of the screw shaft 300 is in sealing contact with the inner sidewall of the mixing tube 200 when the screw shaft 300 is assembled to the mixing tube 200. The outer surface of the screw shaft 300 is provided with a screw groove 301, the screw shaft 300 is clamped in the flow channel, and the screw groove 301 and the inner side wall of the flow channel form a screw flow channel 202. The water supply device and the gas pressurizing device are connected to the input port 121, and the output pipe is connected to the connection portion 201 of the mixing pipe 200.

The water-gas mixing device in the above embodiment is that the input port 121 of the centrifugal pump 100 is connected with the water supply device and the gas pressurizing device, so that water flow and gas with a certain pressure can be input into the centrifugal pump 100, the water and gas are pressurized by the centrifugal pump 100 and then output into the mixing pipe 200 from the output port, when the water flow and gas enter the mixing pipe 200, the water flow and gas can strike the side wall of the spiral groove 301 of the spiral shaft 300 and are conveyed along the spiral groove 301, the water flow and gas can continuously change the direction of the water flow when conveyed in the spiral groove 301 and strike the side wall of the spiral groove 301, the water is cut into a plurality of independent water molecules, the water molecules are recombined after striking, and the gas is wrapped in the water in the combining process, so that the water-gas mixing is realized.

Further, referring to fig. 2, a step 123 is formed between the mixing tube 200 and the output port 122, a clamping groove 124 is formed on an end surface of the step 123, a clamping key 302 is formed on one side of the screw shaft 300, and the clamping key 302 is clamped in the clamping groove 124. Specifically, when the screw shaft 300 is installed into the mixing tube 200, the locking key 302 is locked into the locking groove 124, so that the screw shaft 300 is locked and fixed in the mixing tube 200, and the screw shaft 300 can be prevented from rotating under the impact of high-pressure water flow.

Still further, referring to fig. 2, the locking key 302 is locked in the locking groove 124, and the end of the locking key 302 abuts against the end surface of the locking groove 124, so that a space is formed between the end of the screw shaft 300 and the output port 122. Therefore, after the centrifugal pump 100 pumps out the water flow at high pressure, the water flow can smoothly enter the spiral groove 301, and the water flow is prevented from being excessively blocked by the end surface of the spiral shaft 300.

In this embodiment, when the output pipe is connected to the mixing pipe 200, the screw shaft 300 can be limited by the step surface inside the output pipe, so as to avoid axial movement of the screw shaft 300 in the mixing pipe 200.

Further, referring to fig. 3, the spiral surface of the spiral groove 301 near the output port is distributed with irregular grooves, and the irregular grooves enable the spiral surface to form an uneven surface 304, and the uneven surface 304 is used for increasing the resistance of water flow. Specifically, the spiral surface adjacent to the output port 122 is chemically etched to provide an irregular surface with a concave or convex or frosted surface, so that the spiral surface can increase resistance to water flow. When the water flow is conveyed in the spiral groove 301, the water flow speed near the spiral surface with the concave-convex structure is lower than that of the other spiral surface, so that a flow speed difference is formed, the impact and mixing degree of the water flow in the spiral groove 301 can be increased, the mixing effect of the water and the gas is further increased, and the content of the gas in the water is increased.

Still further, the spiral groove 301 is a smooth surface facing away from the outlet. The difference in flow rate of the water flow in the spiral groove 301 can be further increased.

In a preferred embodiment of the spiral output booster pump device, specifically referring to fig. 3 and 4, the side wall of the spiral groove 301 is further provided with a plurality of through holes 305, and the aperture of the through holes 305 is smaller than 2mm. In this embodiment, when the centrifugal pump 100 inputs water flow and gas into the spiral groove 301, most of the water flow is conveyed along the spiral groove 301, and some of the water flow is directly conveyed axially through the through hole 305; and the water flow conveyed along the through hole 305 and the water flow conveyed along the spiral groove 301 are impacted again, the spiral water flow is cut, and the intensity of the water flow in the spiral groove 301 is further increased, so that the mixing effect is further improved.

Still further, referring to fig. 2 and 3, the spiral groove 301 is a unidirectional left-handed or right-handed spiral groove, so that the water flow is always conveyed along the left-handed or right-handed direction, and the problem that the water flow is broken up again by other impactors after the water and gas are mixed and the gas locked in the water flow is released is ensured.

Further, the spiral angle of the spiral groove 301 is 10 ° to 20 °. The helix angle of the helical groove 301 is preferably 15 °, and at this helix angle, the resistance to water flow can be kept small while ensuring the intensity of the water flow impact when the water flow is conveyed in the helical groove 301.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
