Referring to fig. 1, an oxygen nozzle includes: a water inlet pipe part 100, a water outlet pipe part 200 and an air inlet pipe part 300, wherein a water inlet channel 150 is arranged in the water inlet pipe part 100; the water outlet pipe part 200 is connected with the water inlet pipe part 100, and a water outlet channel 250 is arranged in the water outlet pipe part 200; a necking channel 500 is arranged between the water inlet channel 150 and the water outlet channel 250, the water inlet channel 150 is communicated with the water outlet channel 250 through the necking channel 500, and the inner diameter of the water inlet channel 150 is larger than that of the necking channel 500; the inlet pipe portion 300 is connected to the inlet pipe portion 100 and/or the outlet pipe portion 200, an inlet passage 350 is provided in the inlet pipe portion 300, and the inlet passage 350 communicates with the throat passage 500. After entering the water inlet passage 150 from the water inlet pipe portion 100, the water will gradually flow into the throat passage 500. In this process, since the inner diameter of the throat passage 500 is smaller than that of the inlet passage 150, the flow velocity increases as the water flows from a wide place to a narrow place. From bernoulli's equation, the positive pressure fluid with a high flow rate has a lower pressure and pressure, and therefore, the throat passage 500 has a lower pressure, and a positive pressure difference is generated between the intake passage 350 and the throat passage 500. The pressure difference between the air inlet channel 350 and the throat channel 500 will drive the air in the air inlet channel 350 to enter the throat channel 500 in a pressurized state, and the air is mixed with the water flow in the throat channel 500, so as to achieve the effect of increasing oxygen. Subsequently, the oxygenated water flows out from the water outlet channel 250. Air and water are sufficiently mixed in the throat passage 500 and flow together in the throat passage 500, so that the contact area and the contact time of the air and the water can be effectively increased, and the dissolved oxygen efficiency and the oxygen content in water can be improved. The communication between the necking passage 500 and the intake passage 350 can make the air in the intake passage 350 in a pressurized state when being mixed with the water flow, thereby effectively increasing the mixing effect of the air and the water flow.

And, the oxygen spraying depth of the common oxygen spraying nozzle on the market is about 0.6 m. The product improves the fusion efficiency of water and oxygen, and can better adapt to different use requirements by matching with the deeper oxygen spraying depth of a water pump with larger lift flow and the deepest depth of the water pump can reach 7-8 meters according to Bernoulli's law.

In some embodiments, referring to fig. 2, a junction of the intake passage 350 and the throat passage 500 is provided with a throat 355, and the intake passage 350 and the throat passage 500 communicate through the throat 355; the radial dimension of the junction of the narrowed portion 355 and the constricted passage 500 is smaller than the inner diameter dimension of the intake passage 350. Compared with the air inlet channel 350, the narrow opening portion 355 has a smaller inner diameter size at the connection position of the narrow opening portion 355 and the necking channel 500, so that in the process that air passes through the narrow opening portion 355 from the air inlet channel 350 and enters the interior of the necking channel 500, the flow speed is increased at the narrow opening portion 355, and a pressure difference is generated between the narrow opening portion 355 and the air inlet channel 350, so that the effect that the air enters the necking channel 500 in a compressed state is achieved, and the effect that the air and the water are mixed is effectively increased.

In certain embodiments, referring to fig. 3, the inner diameter dimension of the throat 355 decreases from the inlet passage 350 toward the throat passage 500. The size of the narrow part 355 is changed to gradually increase the flow rate of the air, so that the air can smoothly enter the compressed state gradually, and the air can be effectively ensured to enter the necking passage 500 in the compressed state and be merged with the water flow in the necking passage 500.

In some embodiments, referring to fig. 2, the inlet pipe portion 100 is provided with a first stopper portion 135, and the outlet pipe portion 200 is provided with a second stopper portion 270; one of the inlet pipe portion 100 and the outlet pipe portion 200 extends into the other and allows the first stopper portion 135 and the second stopper portion 270 to cooperate to form a narrowed opening portion 355 and a constricted passage 500. The nested connection of the inlet pipe portion 100 and the outlet pipe portion 200 not only has an advantage of easy installation, but also forms the narrow mouth portion 355 and the constricted passage 500 directly by the first stopper portion 135 and the second stopper portion 270. The narrow mouth part 355 and the necking channel 500 are formed through the matching of the first limiting part 135 and the second limiting part 270, and compared with a conventional machining mode of in-hole cutting, the difficulty of machining and forming the narrow mouth part 355 and the necking channel 500 can be effectively reduced, so that convenience is brought to the production and machining processes.

Specifically, the first stopper 135 extends obliquely toward the central axis of the inlet pipe portion 100, and gradually reduces the inner diameter of the inlet passage 150; the second stopper 270 extends obliquely toward the central axis of the outlet pipe portion 200 such that the inner diameter of the outlet passage 250 is gradually reduced in size.

In some embodiments, referring to fig. 2, the first position-limiting portion 135 is located in the water inlet channel 150, and the second position-limiting portion 270 extends into the water inlet channel 150. The second limiting portion 270 extends into the inlet pipe portion 100, so that the outlet pipe portion 200 is connected with the inlet pipe portion 100 in a nested mode, the second limiting portion 270 can be guided and limited through the inner wall of the inlet pipe portion 100, and therefore the first limiting portion 135 and the second limiting portion 270 can be smoothly matched to form the narrow opening portion 355.

In some embodiments, referring to fig. 3 and 4, the inlet pipe portion 100 is provided with the connecting portion 170, the second stopper portion 270 passes through the connecting portion 170 and extends into the inlet pipe portion 100, and a sealant is disposed between the connecting portion 170 and the second stopper portion 270. The interface 170 can guide and limit the second limiting portion 270, so as to ensure that it can smoothly extend into the water inlet channel 150. The sealant can seal between the interface part 170 and the second limiting part 270, so that the problem of water flow flowing out from the interface part is avoided, and the use stability of the product is improved.

In some embodiments, referring to fig. 2, the inner diameter of the first position-limiting portion 135 gradually decreases toward the outlet pipe portion 200, the inner diameter of the second position-limiting portion 270 gradually decreases toward the inlet pipe portion 100, and the throat passage 500 is located between the first position-limiting portion 135 and the second position-limiting portion 270. The size change of the first and second position-limiting

portions

135 and 270 may make both the water inlet passage 150 and the water outlet passage 250 gradually narrow toward the throat passage 500. The narrowing of the water inlet channel 150 can achieve the effect of increasing the flow rate of the water flow, thereby creating a pressure difference, which can ensure that air enters the throat channel 500 in a pressurized state. The water outlet channel 250 gradually expands towards the direction away from the throat channel 500, so that the water flow in the throat channel 500 can smoothly flow out of the throat channel 500 after being mutually blended with the air, and the water flow after oxygenation can be further ensured to be sprayed out of the oxygen nozzle.

In certain embodiments, referring to FIG. 3, a connecting thread 130 is provided within the water inlet passage 150. The connection screw 130 enables the water pipe portion to be screw-connected to an external water pipe or the like, so that water is conveniently supplied into the water inlet passage 150, thereby facilitating the oxygen increasing operation.

It is contemplated that the inlet pipe portion 100 may be connected to a water pipe or the like by other means, such as a snap (not shown). Therefore, the arrangement of the connection structure on the inlet pipe portion 100 is not exclusive, and can be adjusted according to the actual situation, which is not limited herein.

In some embodiments, referring to FIG. 2, the inner diameter of the inlet channel 150 is greater than the inner diameter of the outlet channel 250. The inner diameter of the inlet passage 150 is not only larger than that of the throat passage 500, but also larger than that of the outlet passage 250. Therefore, the flow rate of the water in the throat 500 and the outlet 250 is greater than that in the inlet 150, so that the accelerated spraying effect of the water is effectively achieved.

The utility model discloses the second aspect provides an oxygen-increasing machine's embodiment, including above oxygen nozzle. After entering the water inlet passage 150 from the water inlet pipe portion 100, the water will gradually flow into the constricted passage 500. In this process, since the inner diameter of the throat passage 500 is smaller than that of the inlet passage 150, the flow velocity increases as the water flows from a wide place to a narrow place. From bernoulli's equation, the positive pressure fluid with a high flow rate has a lower pressure and pressure, and therefore, the throat passage 500 has a lower pressure, and a positive pressure difference is generated between the intake passage 350 and the throat passage 500. The pressure difference between the air inlet channel 350 and the throat channel 500 drives the air in the air inlet channel 350 to enter the throat channel 500 in a compressed state, and the air is mixed with the water flow in the throat channel 500, so that the oxygen increasing effect is achieved. Subsequently, the oxygenated water flows out from the water outlet channel 250. The communication of the converging channel 500 with the intake channel 350 allows the air in the intake channel 350 to be pressurized when combined with the water flow.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
