Description

Technical Field

[0001] The present invention relates to a negative oxygen ion generator, in particular to a swirling water droplet splitting type negative oxygen ion generator. Background Art

[0002] Negative oxygen ions are called "air vitamins". They have the functions of promoting human metabolism, enhancing immunity, anti-oxidation, anti-aging, eliminating free radicals in the body, and calming the mind. When patients inhale air with high concentrations of negative oxygen ions (more than 10,000 / cm³), they can accelerate wound healing and recover early. At the same time, they can purify the air, kill viruses and bacteria, and are beneficial to physical health. Longevity villages around the world are located in high-concentration negative oxygen ion environments with beautiful scenery and fresh air. For example, the negative oxygen ion concentration in Bama, Guangxi is as high as (5,000~20,000 / cm³). The people there are basically free of disease, and the proportion of centenarians is much higher than other places.

[0003] There are two main types of negative oxygen ion generators currently available: one is a corona discharge type negative oxygen ion generator that uses high voltage to ionize the air; the other is a gas-excited negative oxygen ion generator that uses the Lenard effect and the principle of frictional electrification to produce ecological negative oxygen ions. The principle of the Lenard effect is that water hitting air (such as waterfalls and fountains) produces negative oxygen ions, that is, when water becomes mist, positive and negative charges will be separated. Small water droplets separated from the surface of large water droplets are negatively charged, and large water droplets are positively charged.

[0004] Both types of generators currently on the market have been widely used, and multiple invention patents and utility model patent applications have been authorized. For gas-excited negative oxygen ion generators, the current problem is: how to save energy, that is, to use the lowest possible gas pressure to produce the highest possible negative oxygen ion concentration, and achieve the goals of no water spraying, low cost, and low noise.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Example 1

[0024] Reference Figure 1 、 Figure 2 and Figure 3 This embodiment includes a bottle body 1, a middle cover 2, a top cover 3 and a cyclonic negative oxygen ion generator 4. The middle cover 2 is connected to the bottle body 1 and the top cover 3 by a threaded connection or a snap connection. The cyclonic negative oxygen ion generator 4 is arranged in the inner cavity formed by the middle cover 2 and the top cover 3.

[0025] The swirl negative oxygen ion generator 4 includes a generator body 41, an air inlet nozzle 42, a water diversion pipe 43, a partition 44, a gain tube 45, a swirl sheet 46 and an impact plate 47. A partition 44 is provided at the upper end of the generator body 41 and an impact plate 47 is provided at the lower end. An exhaust chamber 5 is formed between the partition 44 and the top cover 3. The partition 44 becomes the interface between the exhaust chamber 5 and the swirl negative oxygen ion generator 4. A gas-liquid diffusion chamber 414 is formed between the generator body 41 and the impact plate 47. The bottom of the gas-liquid diffusion chamber 414 has a second drain port 416. The second drain port 416 is used to drain the accumulated water in the gas-liquid diffusion chamber 414 into the inner cavity of the bottle body 1. The generator body 41 and the air inlet nozzle 42 are detachably connected or integrally formed and form an air inlet gap 411. The generator body 41 has a swirl jet port 412 near the air inlet gap 411.

[0026] A swirl chamber 415 is provided in the middle section of the generator body 41, and a swirl sheet 46 is provided in the swirl chamber 415. The swirl sheet 46 can be inserted and bonded into the swirl chamber 415 or formed integrally with the swirl chamber 415. The swirl sheet 46 is arranged in a spiral shape in the swirl chamber 415. After the compressed air is guided by the swirl sheet 46, the linear motion airflow is converted into a swirl motion airflow. An air inlet nozzle 42 is provided on the upper side of the swirl chamber 415 and is connected to the air inlet 421. The lower end of the swirl chamber 415 is connected to the gas-liquid mixing chamber 413 located in the inner cavity of the gas-liquid diffusion chamber 414 through the air inlet gap 411 and the swirl jet outlet 412. The gas-liquid mixing chamber 413 points to the trumpet-shaped space segment in front of the swirl jet outlet 412. In order to make the diameter of the formed water mist as small as possible, the gas-liquid mixing chamber 413 in front of the swirl jet outlet 412 can be made into the shape of a Laval nozzle such as the jet outlet of an aviation generator.

[0027] One end of the water inlet pipe 43 is set at the swirl jet outlet 412, and the other end is connected to the filter and immersed in the water surface of the inner cavity of the bottle body 1. The gain pipe 45 runs through the generator body 41 and is connected to the gas-liquid diffusion chamber 414 at one end and the exhaust chamber 5 at the other end. The water inlet pipe 43 and the gain pipe 45 are both made of stainless steel pipes or plastic pipes. When compressed air (0.05, 0.1Mpa) is ejected from the swirl jet outlet 412, negative pressure is generated at its center, and the water in the inner cavity of the bottle body 1 is sucked in through the water inlet pipe 43 and discharged from the swirl jet outlet 412. The air is ejected from the swirl jet outlet 412, and a gas-water mixture with a high concentration of negative oxygen ions is formed in the gas-liquid mixing chamber 413 in front of the swirl jet outlet 412. The gas-water mixture diffuses from the gas-liquid mixing chamber 413 to the gas-liquid diffusion chamber 414, and is then transported from the gas-liquid diffusion chamber 414 to the exhaust chamber 5 through the gain tube 45. The negative oxygen ion gas-water mixture rubs and collides with the inner wall of the gain tube 45, further increasing the concentration of negative oxygen ions. Finally, high-concentration (up to 100 million / cubic centimeter) negative oxygen ion air is discharged from the air outlet 32.

[0028] In addition, there is a drainage gap 6 between the outer surface of the generator body 41 and the inner surface of the middle cover 2, and the partition 44 has a first drainage port 441, so that the accumulated water in the drainage cavity is discharged into the inner cavity of the bottle body 1 through the first drainage port 441 and the drainage gap. In this embodiment, the water diversion pipe 43 is a nearly "U"-shaped curved pipe. Example 2

[0029] Reference Figure 4 and Figure 5 This embodiment includes a bottle body 1, a top cover 3, a cyclonic negative oxygen ion generator 4, a one-way valve 7 and a solenoid valve 8. The bottle body 1 and the top cover 3 are threaded and sealed and detachably connected. The cyclonic negative oxygen ion generator 4 is arranged in the inner cavity of the bottle body 1. The cyclonic water droplet splitting negative oxygen ion generator of this embodiment includes three functional chambers:

[0030] ①. The exhaust chamber 5 is formed between the partition 44 and the top cover 3;

[0031] ②. The gas-liquid diffusion chamber 414 in the middle of the generating device body 41 (the lower section of the gas-liquid diffusion chamber 414 is the gas-liquid mixing chamber 413 . In this embodiment, the enterprise mixing chamber is contained in the gas-liquid diffuser);

[0032] ③. The swirl chamber 415 in the lower section of the generating device body 41.

[0033] In this embodiment, the water inlet pipe 43 is a straight pipe, and the cyclone negative oxygen ion generator 4 also includes an air inlet pipe 48, wherein the upper end of the air inlet pipe 48 is connected to the air inlet 421, and the lower end is connected to the cyclone chamber 415 along the tangential direction. The lower end of the cyclone chamber 415 is provided with a third drain port 417, and the third drain port 417 is connected to the solenoid valve 8. A straight water inlet pipe 43 is provided in the center of the cyclone chamber 415, and the lower end of the water inlet pipe 43 extends below the water surface of the inner cavity of the bottle body 1, and the upper end is sleeved on the center of the cyclone jet port 412, wherein the cyclone jet port 412 is a tapered hole and is in an inverted cone shape on the generator body 41. The minimum inner diameter of the cyclone jet port 412 is larger than the outer diameter of the water inlet pipe 43, and the outlet of the cyclone jet port 412 is connected to the gas-liquid mixing chamber 413 and the gas-liquid diffusion chamber 414. The front of the cyclone jet port 412 is 10 to 50 m An impact plate 47 is set at m, and the impact plate 47 is fixed to the top plate of the gas-liquid diffusion chamber 414 by a screw. A gain tube 45 is set on the top plate of the gas-liquid diffusion chamber 414 and passes through the top plate. The lower end of the gain tube 45 is connected to the gas-liquid diffusion chamber 414, and the upper end is connected to the exhaust chamber 5, and is fixed on the partition 44. A water baffle 33 is set 5 to 30 mm in front of the outlet of the gain tube 45. The other side of the water baffle 33 faces the top cover 3 and an air outlet nozzle 31 passing through the top cover 3 is set. A first drain outlet 441 is set on the partition 44 and is connected to the one-way valve 7. In this embodiment, the water inlet pipe 43 and the gain tube 45 are made of metal pipes or plastic pipes, and compressed air with a pressure of 0.05 to 0.1 MPa is used. Negative oxygen ion gas (air or oxygen) with a maximum concentration of negative oxygen ions of 100 million per cubic centimeter can be discharged from the air outlet 32.

[0034] The working principle of the swirl water droplet splitting type negative oxygen ion generator of the present invention is:

[0035] Compressed air enters through the air inlet 421 and enters the swirl chamber 415 along a tangential direction from the air inlet pipe 48, generating a high-speed swirl in the swirl chamber 415 and ejecting swirl air from the swirl jet port 412. Negative pressure is formed at the ends of the water inlet pipe 43 and the swirl jet port 412. Water in the inner cavity of the bottle body 1 is sucked up through the water inlet pipe 43 and ejected from the swirl jet port 412. The negative oxygen ion gas-water mixture impacts the impact plate 47 and is further split into small water particles (water mist). The negative oxygen ion gas-water mixture then rises from the gas-liquid diffusion chamber 414 along the gain tube 45, where it continuously impacts and rubs against each other. Based on the principle of triboelectric charging and the Lenard effect, the concentration of negative oxygen ions is further increased. Finally, the high-concentration negative oxygen ion gas is discharged from the air outlet 32 ​​through the exhaust chamber 5.
