DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Embodiment 1, by Figure 1-Figure 6The present invention comprises an outer circular tube 1, a front cover 2 is welded to one end of the outer circular tube 1, a rear cover 3 is welded to the other end of the outer circular tube 1, a middle partition 4 is welded to one side of the inner part of the outer circular tube 1, a primary mixing chamber 5 is formed between the middle partition 4 and the front cover 2, and a mixing chamber 6 is formed between the middle partition 4 and the rear cover 3.

[0024] A water inlet pipe 7 and an L-shaped air inlet pipe 8 are embedded at one end of the front cover 2 . One end of the water inlet pipe 7 and the L-shaped air inlet pipe 8 are both located in the primary mixing chamber 5 , and the air outlet end of the L-shaped air inlet pipe 8 is connected to one side of the water inlet pipe 7 .

[0025] One end of the rear cover 3 is connected to a water outlet pipe 9 , and the water outlet pipe 9 is located at an eccentric end of the rear cover 3 .

[0026] A first circular cutting piece 10 is embedded in the middle of one end of the middle partition 4, an inner tube 11 is provided inside the mixing chamber 6, one end of the inner tube 11 is connected to the middle partition 4, the first circular cutting piece 10 is coaxial with the inner tube 11, and a sealing plate 12 is welded to the end of the inner tube 11 away from the middle partition 4.

[0027] The inner tube 11 is sleeved with a corrugated spiral tube 13, one end of which is embedded in the middle of the sealing plate 12, and the corrugated spiral tube 13 is connected to the inside of the inner tube 11, and the other end of the corrugated spiral tube 13 is connected to a transition expanding tube 14, one end of which is connected to a second circular cutting piece 15.

[0028] The first circular cutting member 10 and the second circular cutting member 15 both include a cylinder 1001 . Flat notches 1002 are evenly formed on the surface of the cylinder 1001 . Cutting blades 1003 are formed between adjacent flat notches 1002 .

[0029] Working principle: Initial mixing of gas and liquid:

[0030] The water source is introduced into the primary mixing chamber 5 through the water inlet pipe 7. At the same time, the hydrogen and oxygen gases are input through the L-shaped air inlet pipe 8, and its air outlet end is connected to one side of the water inlet pipe 7 to ensure that the gas can enter the primary mixing chamber 5 together with the water flow. In the primary mixing chamber 5, the water source and the hydrogen and oxygen gases are preliminarily mixed to form a gas-liquid mixture.

[0031] First Cutting Breaking:

[0032] After the mixed gas-liquid fluid accumulates a certain pressure in the primary mixing chamber 5, the jet passes through the first circular cutting piece 10 on the middle partition plate 4;

[0033] The first circular cutting member 10 includes a cylinder 1001 with uniform flat notches 1002. Cutting blades 1003 are formed between adjacent flat notches 1002. When the gas-liquid fluid flows through the cutting blades 1003, it is subjected to a strong shear force and is cut into smaller bubbles and enters the inner tube 11.

[0034] Further mixing of gas and liquid and spiral cutting:

[0035] The cut bubble water continues to flow in the inner tube 11 and reaches the sealing plate 12, and the bubble water is blown into the corrugated spiral tube 13. Since the corrugated spiral tube 13 is provided with corrugations on both the inside and the outside, the bubble water enters the corrugated spiral tube 13 under the action of the blowing force, and can be ground into finer nano bubble water under the action of the internal corrugations, and then blown out of the corrugated spiral tube 13 into the mixing chamber 6, and the bubble water continues to be ground under the action of its external corrugations. The design of the corrugated spiral tube 13 enhances the further mixing between gas and liquid. At the same time, its continuous spiral structure generates additional shear force on the gas-liquid mixture, which is conducive to further refinement of the bubbles;

[0036] Second cutting and breaking:

[0037] After further mixing in the corrugated spiral tube 13, the bubble water enters the second circular cutting member 15 through the transfer expansion tube 14;

[0038] The structure of the second circular cutting member 15 is the same as that of the first circular cutting member 10, and also includes a cylinder 1001 with uniform flat notches 1002, which is used to perform a second cutting and crushing of the bubble water to ensure that the bubble size reaches the nanometer level;

[0039] Preferably, in the device, the number of the flat slots 1002 formed on the surface of the first circular cutting member 10 and the second circular cutting member 15 can be determined according to the flow rate in actual application;

[0040] Nano bubble water discharge:

[0041] After being cut and broken twice, the nano bubble water is finally discharged from the water outlet pipe 9. Since the water outlet pipe 9 is arranged at the eccentric end of the rear cover 3, it helps to reduce the fluid pressure loss and ensure the smooth discharge of the nano bubble water. The nano bubble water produced by the device reaches 2nm, which is ultra-fine nanometer, with more than 500 million per milliliter.

[0042] On the other hand, the device can not only produce nano water, but also other liquids, and has a wide range of applications.

[0043] Through the above working principle, the device realizes the effective mixing of water source and hydrogen and oxygen and the generation of nano-bubbles. The device has the advantages of simple structure, convenient operation, high efficiency, uniform bubble size, etc., and is suitable for the preparation of nano-bubble water in various fields.
