[0041] In this embodiment, the negative oxygen ion generating device is integrated inside the cabinet and placed indoors for easy movement, thereby facilitating position adjustment and improving indoor air quality.

[0042] like Figure 6 and Fig.11 As shown, the generator 4 includes a first base 42, a middle conveying member 43 mounted on the first base 42, and an outer matching ring 44 sleeved on the outside of the middle conveying member 43; the middle of the middle conveying member 43 is provided with a water outlet 431 connected to the water pipe 21, and the side of the middle conveying member 43 is provided with a plurality of air outlets 432 connected to the air pipe 11; the air outlets 432 are provided with 8, such as Figure 7 As shown, the external matching ring 44 is provided with a first through hole 441, the end of the middle conveying member 43 is installed inside the first through hole 441, and a high-pressure air annular outlet 442 connected with the air outlet 432 is installed between the end of the middle conveying member 43 and the first through hole 441; the high-pressure air annular outlet 442 sprays out the high-pressure air to further pressurize the high-pressure air; the water outlet 431 discharges water outward, which is cut and crushed by the high-pressure air annular shape to form negative oxygen ions, and the negative oxygen ions are discharged to the outside through the generator 4.

[0043] Further, such as Fig.11As shown, the water column output by the water outlet 431 is surrounded by annular high-pressure air, and the annular high-pressure air performs annular impact on the water column, tearing, impacting, cutting, and smashing the water molecules, so that the airflow and the water molecules are fully mixed, thereby generating more negative oxygen ions; the negative oxygen ions produced by the annular high-pressure air cutting, smashing, and tearing the water molecules are many times that of the point-like surface impact, and more negative oxygen ions can be generated, resulting in a high concentration of negative oxygen ions output by the generator 4.

[0044] Furthermore, if Fig.11 As shown, the middle conveying member 43 is threadedly connected to the first base 42, and a sealing ring 46 is installed between the middle conveying member 43 and the first base 42 to increase the sealing between the middle conveying member 43 and the first base 42; a fixing ring 45 is sleeved on the outside of the external matching ring 44, and the fixing ring 45 threadably fixes the middle conveying member 43 and the external matching ring 44; the above-mentioned split structure is easy to disassemble, which can facilitate subsequent repair and maintenance and reduce maintenance costs.

[0047] Similarly, a first annular inclined surface 438 is provided at the end of the water outlet hole 431. The first annular inclined surface 438 pressurizes the output water, so that the water outlet speed of the first annular inclined surface 438 can be increased several times.

[0048] like Figure 4 As shown, the generator 4 is installed horizontally and vertically on the mounting base 6, and 8 generators 4 are installed on the mounting base 6; Fig.13As shown, one side of the mounting base 6 is connected to the air pipe 11, and the other side is connected to the water pipe 21. The air pipe 11 is connected to each generator 4 to input high-pressure air into the generator 4, and the water pipe 21 is also connected to each generator 4 to input water into the generator 4.

[0049] like Figure 3 As shown, the mounting seat 6 is installed inside the collecting funnel 5, and the air pipe 11 and the water pipe 21 pass through the collecting funnel 5 and are connected to the mounting seat 6; the collecting funnel 5 collects water and flows it back to the main water pipe 2 through the return pipe 8, thereby realizing the recycling of water and ensuring that the water resources in the main water pipe 2 are fully utilized.

[0050] like Figure 4 As shown, the rear side or front side of the mounting seat 6 is equipped with a fan 7. Generally, in order not to block the flow of negative oxygen ions, the fan 7 is installed on the rear side of the mounting seat 6, and the installation sequence is: fan 7, generator 4, wind guide device 95; in other embodiments, the fan 7 is installed on the front side of the mounting seat 6, and the installation sequence is: generator 4, fan 7, wind guide device 95.

[0054] Furthermore, in this embodiment, the cabinet is placed vertically. Figure 1 As shown, the air guide device 95 is placed horizontally, and the negative oxygen ions are ejected horizontally from the top; when the air guide device 95 is placed vertically, the negative oxygen ions are ejected vertically from the top; the air guide device 95 can also be placed and controlled at multiple angles, so that the negative oxygen ions can be ejected from multiple angles; thereby, the negative oxygen ions can be output to any place; in short, the air guide device 95 can be naturally adjusted and adjusted according to actual conditions, so as to facilitate the transportation and diffusion of negative oxygen ions and improve indoor air quality.

[0055] like Figure 1 As shown, a plurality of ventilation holes are provided at appropriate positions of the first cabinet 91 and the second cabinet 92 so that the air inside the cabinets can flow fully, so that the negative oxygen ions can be discharged quickly and fully, and it is also beneficial for the compressor 1 to absorb external air.

[0056] Specifically, the ventilation holes can be relatively arranged on two side surfaces, one of which inhales air and the other exhausts air to form a horizontal air duct; the ventilation holes can also be arranged vertically on two side surfaces, one of which inhales air and the other exhausts air to form a vertical air duct; multiple ventilation holes can also be arranged, one of which inhales air and the other exhausts air.

[0060] The operation process of the negative oxygen ion generating device is as follows: first, the dustproof door 94 is opened, and a sufficient amount of water is added to the water storage tank 3; secondly, the compressor 1 is started, and high-pressure air is input into the generator 4 through the air pipe 11; the water pump 22 is started, and the water pump 22 inputs water into the generator 4 through the water pipe 21; thirdly, the high-pressure air passes through the air pipe 11, the second threaded hole 427, the second connecting hole 428, and the air outlet 432 in sequence, reaches the high-pressure air annular outlet 442 and is ejected outward; the water passes through the water pipe 21, the first threaded hole 425, the first connecting hole 426, and the water outlet 431 in sequence, and is cut and crushed by the high-pressure air annular outlet to form negative oxygen ions; finally, a part of the negative oxygen ions is accelerated outward by the fan 7 and discharged outward through the air guide device 95; the other part is re-condensed into water, and the water is guided by the guide arc surface 54 to flow into the water collecting V-shaped groove 53, and flows back to the main water pipe 2 through the return pipe 8, thereby realizing the recycling of water and ensuring that the water resources in the main water pipe 2 are fully utilized.
