Technical Field

[0001] This invention relates to the technical field of negative oxygen ion generators, and particularly to a gas-induced negative oxygen ion generator. Background Technology

[0002] In existing technologies, negative ion generators often utilize the principle of air-induced generation, which involves using high-pressure air to impact a liquid, thereby producing negative ions. Current negative ion generators mainly consist of a generator and an air compressor, with the compressor providing a stable, high-speed airflow to the generator.

[0003] Indoor air quality is generally poor, and opening windows for ventilation is often the only way to improve it.

Furthermore, when negative ion therapy or maintenance is needed, it's difficult to provide sufficient negative ions at home, making it hard to receive timely treatment. Therefore, providing a cabinet-style negative ion generator for indoor use is essential and can significantly improve indoor air quality. Summary of the Invention

[0033] The technical solution of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please refer to Figures 1 to 13 The present invention provides a negative oxygen ion generating device.

[0035] like Figure 1 As shown, the negative oxygen ion generator is placed inside the cabinet, so it can be placed indoors and output more negative oxygen ions, which is beneficial to improving indoor air quality.

[0036] Furthermore, in this embodiment, the cabinet is placed vertically, such as... Figure 1 As shown, when the generator 4 is placed on the upper part of the cabinet, the negative oxygen ions are sprayed horizontally from the top; when the generator 4 is placed vertically, the negative oxygen ions are sprayed vertically from the top; the cabinet can also be placed horizontally, and when the generator 4 is placed on the upper part of the cabinet, the negative oxygen ions are sprayed horizontally from the top; when the generator 4 is placed vertically, the negative oxygen ions are sprayed horizontally from both sides; a pipe can also be connected to the negative oxygen ion outlet to output the negative oxygen ions to any location; in short, the placement position can be naturally adjusted according to the actual situation to generate more negative oxygen ions and improve indoor air quality.

[0037] Specifically, the cabinet includes a first cabinet 91 and a second cabinet 92; in other embodiments, the negative ion generator can also be placed inside the furniture to enhance its function and reduce the space occupied in the room. The placement location can be freely chosen according to actual needs.

[0038] Furthermore, such as Figure 3 As shown, the negative oxygen ion generator includes a compressor 1, which compresses air and outputs high-pressure air. A main water pipe 2 is installed on one side of the compressor 1, and the main water pipe 2 stores water as a water storage chamber. The main water pipe 2 is connected to a water tank 3, allowing water to be replenished from the water tank 3 during use, or manually. Furthermore, the compressor 1 and the main water pipe 2 are installed at the bottom, inside the second cabinet 92, while the water tank 3 is located above the main water pipe 2, inside the third cabinet 93 within the first cabinet 91, facilitating water replenishment.

[0039] like Figure 3As shown, at least one generator 4 is installed on the upper part of the compressor 1 and the main water pipe 2. Further, as... Figure 4 As shown, the generators 4 are arranged horizontally and vertically, with eight units in total. The compressor 1 inputs high-pressure air into the generators 4 through the air supply pipe 11. The main water pipe 2 is connected to the generators 4 through the water supply pipe 21, and a water pump 22 is installed on the water supply pipe 21. The water pump 22 inputs water into the generators 4 through the water supply pipe 21. The water inside the generators 4 is cut and broken by the high-pressure air to form negative oxygen ions. A portion of the negative oxygen ions are discharged to the outside through the generators 4, and the other portion is re-condensed into water and collected through the collecting funnel 5, and flows back to the main water pipe 2 through the return water pipe 8.

[0040] Furthermore, the generator 4 and the collecting funnel 5 are placed inside the first cabinet 91, which is located above the second cabinet 92. A wind guide device 95 is provided on one side of the first cabinet 91, which corresponds to the generator 4, thereby forming a fixed air duct to facilitate the discharge of negative oxygen ions.

[0041] In this embodiment, the negative oxygen ion generator is integrated inside the cabinet and placed indoors, making it easy to move and adjust its position, and also helping to improve indoor air quality.

[0042] like Figure 6 and Figure 11 As shown, the generator 4 includes a first base 42, a central conveying component 43 mounted on the first base 42, and an outer mating ring 44 sleeved around the central conveying component 43; the central conveying component 43 has a water outlet 431 connected to the water supply pipe 21 in its center, and several air outlets 432 connected to the air supply pipe 11 are provided on the side of the central conveying component 43; there are 8 air outlets 432, such as... Figure 7 As shown, the outer mating ring 44 is provided with a first through hole 441. The end of the middle conveying component 43 is installed inside the first through hole 441. A high-pressure air annular outlet 442 connected to the air outlet 432 is installed between the end of the middle conveying component 43 and the first through hole 441. The high-pressure air annular outlet 442 sprays out high-pressure air to further pressurize it. Water flows out of the water outlet 431 and is cut and broken by the high-pressure air annularly to form negative oxygen ions. The negative oxygen ions are discharged to the outside through the generator 4.

[0043] Furthermore, such as Figure 11As shown, the water column output from the water outlet 431 is surrounded by annular high-pressure air. The annular high-pressure air impacts the water column in an annular manner, tearing, impacting, cutting, and shattering the water molecules, so that the airflow and water molecules are fully mixed, thereby generating more negative oxygen ions. The negative oxygen ions produced by the annular high-pressure air cutting, shattering, and tearing the water molecules are many times greater than those produced by point-area impact, which can generate more negative oxygen ions, resulting in a high concentration of negative oxygen ions output by generator 4.

[0044] Furthermore, such as Figure 11 As shown, the central conveyor 43 is threadedly connected to the first base 42, and a sealing ring 46 is installed between the central conveyor 43 and the first base 42 to increase the sealing performance between them. A fixing ring 45 is fitted around the outer mating ring 44, and the fixing ring 45 threadedly fixes the central conveyor 43 and the outer mating ring 44. The above-mentioned split structure facilitates disassembly, which can facilitate subsequent maintenance and reduce maintenance costs.

[0045] like Figure 11 As shown, the first base 42 has a first threaded hole 425 on one side for connecting to the water pipe 21, as... Figure 8 As shown, the first base 4243 is provided with a first connecting hole 426, which connects the first threaded hole 425 to the water outlet 431; Figure 11 As shown, the other side of the first base 42 is provided with a second threaded hole 427 for connecting to the gas pipeline 11, as... Figure 8 As shown, the first base 42 is provided with a second connecting hole 428, which connects the second threaded hole 427 to the air outlet 432.

[0046] like Figure 11 As shown, the middle conveyor 43 has a second annular inclined surface 439 on its side. The second annular inclined surface 439 guides high-pressure air into the high-pressure air annular outlet 442. The area of ​​the lower port of the second annular inclined surface 439 is much larger than the area of ​​the upper port. This allows the high-pressure air speed to be increased many times when it enters the high-pressure air annular outlet 442.

[0047] Similarly, the end of the water outlet 431 is provided with a first annular inclined surface 438, which pressurizes the output water, thereby increasing the water outlet speed of the first annular inclined surface 438 by several times.

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

[0049] like Figure 3 As shown, the mounting base 6 is installed inside the collecting funnel 5, and the air supply pipe 11 and water supply pipe 21 pass through the collecting funnel 5 and are connected to the mounting base 6; the collecting funnel 5 collects water and flows back to the main water pipe 2 through the return water 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, a fan 7 is installed on the rear or front side of the mounting base 6. Generally, to avoid obstructing the flow of negative oxygen ions, the fan 7 is installed on the rear side of the mounting base 6, with the installation sequence being: fan 7, generator 4, and air guide device 95. In other embodiments, the fan 7 is installed on the front side of the mounting base 6, with the installation sequence being: generator 4, fan 7, and air guide device 95. The fan 7 can accelerate the discharge of negative oxygen ions; for example... Figure 5 As shown, in order to accommodate the fan setup, the collecting funnel 5 includes an air inlet 51 on one side and a negative oxygen ion outlet 52 on the other side.

[0051] Furthermore, the collecting funnel 5 also includes a water collecting V-shaped groove 53 installed on the lower side and a guiding arc surface 54 for guiding; the guiding arc surface 54 guides water to flow into the water collecting V-shaped groove 53, and finally flows back to the main water pipe 2 through the return water pipe 8, thereby realizing the recycling of water and ensuring that the water resources in the main water pipe 2 are fully utilized.

[0052] like Figure 2 As shown, the first cabinet 91 has a third cabinet 93 inside for accommodating the water storage tank 3, as... Figure 1 As shown, the third cabinet 93 is equipped with a dustproof door 94 that is easy to open. When the dustproof door 94 is opened, water can be added to the water storage tank 3, or bottled water or barrelled water can be directly replaced.

[0053] The upper part of the first cabinet 91 is provided with an air guide device 95, which corresponds to the generator 4 and the fan 7 to form an air duct. The fan 7 drives the negative oxygen ions inside the air duct, which facilitates the discharge and long-distance transportation of negative oxygen ions. The air guide device 95 is an air guide louver. The angle between the air guide louver and the first cabinet 91 can be manually controlled to transport negative oxygen ions to the target location. The angle between the air guide louver and the first cabinet 91 can also be controlled by a motor. In addition, the air guide louver can be cyclically oscillated by controlling the forward and reverse rotation of the motor. Multi-angle control and cyclic control are achieved to facilitate the transportation and diffusion of negative oxygen ions.

[0054] Furthermore, in this embodiment, the cabinet is placed vertically, such as... Figure 1 As shown, when the air guide device 95 is placed horizontally, 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 outputting the negative oxygen ions to any location; in short, the air guide device 95 can be naturally adjusted and modified according to actual conditions, thereby facilitating the transport and diffusion of negative oxygen ions and improving indoor air quality.

[0055] like Figure 1 As shown, several ventilation holes are set at appropriate positions in the first cabinet 91 and the second cabinet 92 to allow the air inside the cabinet to circulate fully, so that negative oxygen ions can be quickly and fully discharged, and it is also beneficial for the compressor 1 to draw in external air.

[0056] Specifically, the ventilation holes can be arranged opposite each other on both sides, with one ventilation hole drawing in air and the other venting air out, forming a horizontal airflow channel; the ventilation holes can also be arranged vertically on both sides, with one ventilation hole drawing in air and the other venting air out, forming a vertical airflow channel; multiple ventilation holes can also be provided, with one ventilation hole drawing in air and the others venting air out. The ventilation holes can be naturally adjusted according to actual conditions, and in this embodiment, there is no limitation, as long as the number and location are reasonable.

[0057] Furthermore, a filter 97 is installed on the ventilation opening; the filter 97 effectively removes particulate matter, dust, and other impurities from the air, ensuring that the air entering the compressor 1 is relatively clean. The removable design of the filter 97 facilitates regular cleaning or replacement by the user. This design helps maintain the efficient operation of the equipment and extends the service life of the filter 97.

[0058] like Figure 1As shown, the first cabinet 91 is also equipped with a main control screen 96. Specifically, the main control screen 96 can display the operation process of the negative oxygen ion generator, and can also directly control or interfere with the control of the negative oxygen ion generator.

[0059] like Figure 3 As shown, the main water pipe 2 is equipped with rotating plugs 23 or drain valves at both ends; the rotating plugs 23 or drain valves pass through the second cabinet 92 and are connected to the main water pipe 2; when it is necessary to clean the internal water pipes, the rotating plugs 23 can be disassembled or the drain valves can be opened.

[0060] The operation process of the negative oxygen ion generator is as follows: First, open the dustproof door 94 and add sufficient water to the water storage tank 3; second, start the compressor 1 and input high-pressure air into the generator 4 through the air supply pipe 11; start the water pump 22, which inputs water into the generator 4 through the water supply pipe 21; third, the high-pressure air passes through the air supply pipe 11, the second threaded hole 427, the second connecting hole 428, and the air outlet 432 in sequence, and is sprayed outward at the high-pressure air annular outlet 442; the water passes through the water supply pipe 21, the first threaded hole 425, the first connecting hole 426, and the water outlet 431 in sequence, and is cut and broken by the high-pressure air annularly to form negative oxygen ions; finally, a portion of the negative oxygen ions is accelerated outward by the fan 7 and discharged outward through the air guide device 95; the other portion is recondensed into water and guided by the guide arc surface 54 to flow into the water collection V-shaped groove 53, and flows back into the main water pipe 2 through the return water pipe 8, thereby realizing the recycling of water and ensuring that the water resources in the main water pipe 2 are fully utilized.

[0061] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
