A vehicle-mounted negative ion air purifier using a high-frequency transformer

Abstract

The invention discloses a vehicle-mounted negative ion air purifier adopting a high-frequency transformer.The vehicle-mounted negative ion air purifier comprises an upper shell, a lower shell and a negative ion generating device, the negative ion generating device comprises a heating electrode, a low voltage electrode, a transformer, a pulse width modulation circuit, a drive circuit, an inverter circuit, the boosting transformer and a high voltage rectification filter circuit, the boosting transformer comprises a electric discharge winding and a heating winding, the generation amount of negative corona electric discharge ozone is reduced through a heating electrode heating technology, the negative ion air purifier can work in a high electric field area, high concentration negative oxygen ions are further generated, efficiency of the negative ion air purifier is improved, the content of negative oxygen ions inside a vehicle is raised, the vehicle-mounted negative ion air purifier is beneficial to human health, the ozone concentration is far lower than the indoor air quality standards, and ultraviolet light generated by strong negative corona discharge has the functions of disinfection and sterilization.By means of the vehicle-mounted negative ion air purifier, the defect that old type air purifying machines generate negative ions through needle points is effectively overcome, the generated negative ions are large in concentration and uniform, and the amount of generated ozone is extremely small.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a vehicle-mounted air purifier for purifying the air in a vehicle. Background technique [0002] Due to the acceleration of industrialization and urbanization, in modern life, the air in people's living and working places is polluted to varying degrees. Gradually attracting people's attention, the air pollution sources in the car mainly come from the car body itself, decorative materials, etc., and various solvent-based adhesives are used in the car interior, such as: wallpaper adhesives, carpet adhesives, and sealing adhesives , plastic adhesives, etc. During the use of adhesives, formaldehyde, benzene, toluene, xylene and other volatile organic compounds will be released, causing people to be poisoned unconsciously, and symptoms such as headache and fatigue will gradually appear. In severe cases, dermatitis, asthma, low immunity, and even leukopenia will occur. [0...

Problems solved by technology

[0004] In order to solve the problem of air pollution in the car and improve the air quality in the car, those skilled in the art are also making technical improvements. For example, the Chinese patent with application number CN201310384845.0 discloses a car purifier, which uses a negative ion generator Combining with the aroma box can effectively purify the air in the car and remove odors, but only relying on negative ion generators for sterilization, the sterilization method is single, and the sterilization effect has not reached the ideal expectation. Therefore, there is an urgent need for a more effective sterilization Excellent Car Air Purifier

[0005] The negative ion air purifier can effectively eliminate positively charged ions harmful to the human body such as dust, pollen, bacteria, viruses, exhaust gas, smoke and peculiar smell in the air, and it is also effective for asthma, bronchitis, allergic rhinitis and other diseases. It has a certain therapeutic effect, so people began to develop negative ion air purifiers, but the existing negative ion air purifiers generate negative ions by high-voltage needle tip discharge, and the air purifier with this structure will generate a certain amount during the needle tip discharge process. Ozone harmful to the human body and a high voltage of more than 7000V will be generated in the discharge of the needle tip. Human and animal bodies cannot directly touch the needle tip, which will pose a safety hazard during use. The output of negative ions and the increase of ozone production will affect the function of purifying the air. It needs to be cleaned and replaced frequently, which is time-consuming and laborious. However, it is difficult for ordinary users to grasp the methods and conditions of cleaning and replacement, thus affecting its popularization and application.
