Description
Technical Field
The utility model relates to an anion generator, in particular to an anion generator for an air disinfection and purification device.
Background
Air ions have a certain influence on human health. Ions in the atmosphere can be divided into three major classes:
(1) light ion-it is a charged aggregate composed of several neutral molecules. Negatively charged light ions are commonly referred to as negative ions; light ions with positive charges are called positive ions.
(2) And (3) neutral ion: it is also a very small charged particle containing around 100 gas molecules.
(3) Heavy ion: it is a large charged particle, about 1000 times larger than light ions. Heavy ions in the air are easy to collect and remove, and the number of the air after being purified is small.
Of interest to the purification process are light and medium ions. Since outdoor air generally contains a few light ions, and urban air is polluted and often lacks light ions, the light ions make up the main component of air. Air-conditioned rooms generally require a small number of light ions, particularly negative ions. Because the negative ions can play a role in calming the nervous system of a human body, promoting the elimination of fatigue, inhibiting asthma and reducing blood pressure. The light ions have a short lifetime and will disappear quickly after contacting the metal surface during the air heating, cooling and filtering process. Therefore, if no measures are taken, the light ion density of the air-conditioned room is less than half of that of the outside. In order to improve sanitary conditions, a negative ion generator should be installed in the air-conditioned room. There are many methods of generating negative ions and,
the most common method is corona discharge. It uses the non-uniform electric field generated between needle electrode and flat electrode under the action of high voltage to make the air flowing through be ionized. In the figure, a negative high voltage pulse is applied to a thin metal wire to ionize air beside the thin wire. The positive ions are absorbed on the thin wires, the negative ions move to the metal mesh electrode, and the negative ions are taken away from the metal mesh openings under the action of wind force. The amount of ions generated is related to the wind speed, which is usually less than 10m/s, with a pulse voltage of typically 50kV and a pulse frequency of 50 Hz. When the input power is 50W, the number of ions generated is about 5x1010-5x1011Per second.
The main working principles of the current anion generators are as follows according to the appearance time sequence:
1. bipolar corona discharge technique: the method is characterized in that positive high voltage and negative high voltage are loaded on two electrodes respectively, an uneven electric field is formed between the two electrodes, corona discharge is generated, air flowing through is ionized, and air ions are generated. Many negative ion generators on the market currently adopt a bipolar corona method to generate negative ions, and the method has the defects that the concentration of the generated negative ions is generally not high, heavy ions and medium ions with large particle sizes are taken as main materials, the expansion performance is poor, and positive ions and ozone are generated.
2. The common unipolar discharge technology generally adopts unipolar negative high voltage as an electron release source, an electron release electrode adopts a needle-shaped metal tip or a common carbon fiber tip, electrons are continuously released to a space through the electron release electrode, and the electrons are combined with oxygen molecules in the air to generate negative oxygen ions. The concentration of negative oxygen ions generated by the method is generally higher, the diffusion performance is good, but certain ozone and oxynitride can be generated.
3. The nano fullerene ion releaser technology is characterized by that it utilizes nano fullerene as discharge electrode, and the fullerene is an electrocatalytic material made up by adopting nano technology, and is a material close to superconduction, and its resistance is almost equal to zero. When the ions pass through the material, a strong resonance effect is generated, which is extremely beneficial to the free precipitation of the ions, unlike the traditional ion release material (common carbon fiber or metal, etc.) which needs a strong current to output ions with higher concentration. It can release negative oxygen ions with large dose and high purity only by weak current, and can form a pure ecological negative oxygen ion bath environment in space. Meanwhile, no derived pollutants such as ozone, nitrogen oxide and the like are generated.
4. Anion converter technology: the anion converter is a conversion device applied to air anion generating equipment, and can convert artificially generated anions into small-particle-size anions equivalent to nature. The small-particle-size air negative ions have high activity and long migration distance, and the air negative ions are diffused to the distance of 4-5 meters under the condition of not using a fan to blow outside, so that the zero-noise operation of the product is realized.
5. Ecological anion generation chip technology: the ecological negative ion generating chip is formed by highly integrating a piezoelectric ceramic negative ion generator and an ion converter. The piezoelectric ceramic negative ion generator can inhibit and eliminate the adverse effects of positive ions and the like generated by the traditional negative ion generator, and greatly reduces the volume and thickness of the negative ion generator. By using the ecological anion generating chip technology, not only can ecological anions with large dose, high purity, small particle size and high activity be generated, but also the volume of anion products is greatly reduced, the space is saved more, and the removal is convenient.
6. Ecological anion generation technology with anion system and pollutant collection system: the negative ion generator is characterized in that a collector with a pollutant collecting function is added on the basis of a negative ion generator using a negative ion converter technology or an ecological negative ion generating chip technology, negative ions are released into space and then are rapidly combined with pollutants, one part of the negative ions are condensed into large particles to be settled, and the other part of the negative ions are combined with the principle that the negative ions are negatively charged due to positive and negative attraction and are adsorbed onto the pollutant collector, so that the purification efficiency of the negative ion generator is greatly improved.
The more advanced the technology in the later period, the higher the concentration and purity of generated negative ions, and the more stable the performance.
At present, there are cases in which an anion generating device is applied to air purification products, for example, chinese patent CN110030639A discloses an intelligent air purification apparatus, which includes a mounting plate, a groove is formed on a bottom side wall of the mounting plate, a slide rail is fixed on an inner wall of the groove by rivets, a hydraulic rod is slidably connected to a side wall of the slide rail, a display screen is fixed on a side wall of the mounting plate close to the slide rail by screws, a purification chamber is fixed at one end of the hydraulic rod by screws, a groove is formed on an inner wall of the purification chamber, a motor is disposed on the inner wall of the groove, an output end of the motor is connected to a shaft sleeve, a second fan blade is welded on an outer wall of the shaft sleeve, a connecting rod is slidably connected to an outer wall of the shaft sleeve close to the second fan blade, air sucked into the purification chamber through an air inlet duct can be sequentially and sufficiently purified, the freshness of the purified air is ensured, and the safety of the purified air is improved.
However, the negative ion generating part adopts a negative ion generating net, so that the controllability is poor, and an independent power supply is not designed for supplying power, so that interference is easily caused, and the work of other power utilization modules is influenced.
