[0029] In the embodiment, the curvature radius r of the tip of the electrode body is 0.02 mm.

[0030] In the embodiment, the tip curvature radius r of the negative electrode sheet is 0.02 mm.

[0031] In the embodiment, the negative electrode is made of stainless steel.

[0032] In the embodiment, the positive electrode is made of tungsten carbide hard alloy.

[0033] Example 2

[0034] In this example, the electrode assembly in Example 1 was used.

[0035] See also Figures 1 to 9 A negative ion generating module comprises a shell 1 (made of PBT material), a motor 2 is installed in the shell 1, an electrode base 3 (made of PTFE material) is arranged on the output shaft of the motor 2, a positive electrode 41 (made of SUS material) is arranged on the electrode base 3, a negative electrode 51 is arranged on the side away from the positive electrode in the shell 1, a positive high-voltage circuit 42 and a negative high-voltage circuit 52 are arranged in the shell 1, the positive high-voltage circuit 42 is connected to the positive electrode 41, the negative high-voltage circuit 52 is connected to the negative electrode 51, and an end cap 1a is arranged at the end of the shell 1; a control module and a humidity sensor for detecting the humidity in the shell are arranged in the shell 1, and the motor, the humidity sensor, the positive high-voltage circuit and the negative high-voltage circuit are all connected to the control module.

[0036] In the embodiment, the positive high voltage circuit generates a voltage of 4.5-5.0 KV, and the negative high voltage circuit generates a voltage of 6.0-6.5 KV.

[0037] In the embodiment, a shielding layer 1b (made of metal material, refer to the prior art) is arranged outside the shell 1, and a shielding layer opening is arranged on the shielding layer 1b.

[0038] In the embodiment, the positive electrode 41 includes a plurality of circumferentially arranged electrode bodies, the electrode body having a main body, and a plurality of spiral grooves are provided on the main body. Each spiral groove extends from the lower part of the main body to a position close to the tip. The bottom area of ​​the main body is the installation part.

[0039] In the embodiment, the negative electrode 51 has an electrode ring 51a (ring structure), and a plurality of negative electrode sheets 51b are arranged on the inner upper part of the electrode ring 51a. There are six negative electrode sheets 51b, each of which is roughly triangular, and an electrode ring notch is provided on one side of each negative electrode sheet 51b.

[0040] Through the positive high voltage output, the positive electrode (spiral electrode) is used to output the negative high voltage (ring tip electrode) for mutual ionization, and a step ionization form is formed. This ionization structure ionizes the outer electrons of the atom for the second time (ionization by the positive high voltage electrode is the first ionization, and ionization by the negative high voltage electrode is the second ionization). Since the ionization potential energy of the second ionization is higher than that of the first ionization (the first ionization high voltage is set to 4.5-5.0KV, and the second ionization high voltage is set to 6.0-6.5KV), the electrons escaping from the atom in the second ionization will obtain additional kinetic energy.

[0041] The spiral electrode (made of tungsten carbide, the curvature radius r of the electrode tip is 0.02mm) is used. This material has the characteristics of high hardness and corrosion resistance. The spiral electrode shape can greatly increase the electrode surface area (2-3 times) under the same volume electrode shape. The larger the electrode surface area interface, the greater the current density, which greatly increases the reaction rate on the electrode, and the ionization electric field distribution will be more uniform. The ionization electric field lines quickly accelerate and gather in a spiral shape toward the spiral tip through the end of the spiral line, thereby improving the ionization effect and ionization potential energy.

[0042] The annular tip electrode (made of stainless steel, with a tip curvature radius r of 0.02 mm at the tip release point) adopts an integrated annular guide and tip ionization release structure. The annular structure is used as an ionization guide near the inner cavity ionization field (so that the swirling ion wind generated by the positive ionization electrode is quickly guided to the release port), and the tip ionization release near the release port forms secondary ionization to quickly and evenly distribute and release negatively charged ions from the release port.

[0043] Due to the change of environmental humidity, the ionization intensity in the cavity will be different, resulting in ionization glow, ionization noise, and ozone damage. The humidity sensor detects the humidity in the shell cavity. The control module controls the lifting motor to adjust the distance between the two electrodes according to the detected humidity value, thereby reducing the ionization glow, ionization noise, and ozone damage caused by humidity. Among them, the distance between the positive electrode and the negative electrode is L, see Fig. 9, that is: the distance from the tip of the positive electrode to the lower end of the annular part of the negative electrode is L, and the relationship between the humidity value and the distance between the positive and negative electrodes L is as follows: the relative humidity of the indoor living space is generally in the range of 30-80%. The higher the relative humidity of the space, the farther the distance between the positive and negative electrodes. The following is an example: when the humidity is 30-45%, 46-55%, 56-65%, and 66-80%, the distance between the electrodes L is 30mm, 31mm, 32mm, and 33mm respectively. It should be noted that the above correspondence between humidity and electrode distance is only an example and can be adjusted as needed.

[0044] The present invention has the following characteristics:

[0045] (1) The present invention can realize the formation of high-density plasma (disinfection and sterilization factor) inside the module cavity, and the release port only releases stable and high-concentration negative ions and does not form ozone, static electricity and other harmful ionized form-derived substances that are harmful to the human body.

[0046] (2) In the chamber of the present invention, the positive high voltage (4.5-5.0KV) ionization generating electrode (spiral electrode) and the negative high voltage (6.0-6.5KV) ionization generating electrode (ring tip electrode) are connected at a set distance (30-35mm) through the humidity sensor in the control circuit to transmit the set signal to drive the spacing adjustment motor to adjust the distance, and the positive and negative voltage difference is controlled between 10.5-11.5KV. This technology can achieve no glow discharge phenomenon and no ionization noise in an environment with a relative humidity of 80%.

[0047] (3) The negative ions generated and released by the present invention can be released in all directions in a space of 360° within a distance of one meter, and the ion stability and diffusion angle are better than the pushing effect of the rear-driven wind ion technology. Through the switch test (testing the gradual decrease of the negative ion concentration in the air after the module product is powered off), the half-life of the negative ions reaches 30-45 seconds.

[0048] (4) The present invention forms a high-density plasma in the inner cavity of the module through the mutual ionization of positive and negative ions. Through different application forms, a turbo fan or other wind-driven forms can be used to precipitate the plasma from the inner cavity, which has the effect of efficiently and quickly disinfecting the ambient air and quickly eliminating organic volatile substances (combustion smoke and odor) in the ambient air.

[0049] (5) The present invention can achieve the ion wind pushing effect through positive and negative dual high-voltage interactive ionization technology, setting the release electrode shape and ionization distance control, etc.

[0050] (6) The present invention has a wide range of applications, including but not limited to windless negative ion products, air plasma disinfection products, smoke removal / odor removal equipment, engineering air duct equipment and other fields.

[0051] Example 3

[0052] The basic scheme is the same as Example 2, except that a gain ring 1c (made of SUS material) is provided in the housing 1. By adding a metal gain ring structure in the polar field cavity, the polar field distribution in the cavity can be made more balanced and stable, so that the ionization field lines in the positive and negative alternating ionization fields have more stable guidance. The stable ionization field distribution enables the ion wind in the cavity to precipitate efficiently and continuously. After adding the gain ring, the negative ion concentration at one meter of the release port is increased by 30-50% through testing, and the value change tends to be more stable.

Since the first carrier and the second carrier are arranged on their respective carrying structures, and the second carrier is convenient for installation on the supporting equipment, the first carrier can be quickly distributed to the lifting structure to meet the adjustment of the inter-electrode distance between the two carrier electrodes to adapt to different environments.

A plurality of negative electrode sheets 51b are arranged on the upper inner side of the electrode ring 51a, for example, six triangular electrode sheets, the negative electrode sheet 51b is placed at the notch, and the negative electrode sheet and the electrode ring are a stamped integral part.
