Description

Technical Field

[0001] The utility model belongs to the technical field of air purifiers, and in particular relates to a sterilization component utilizing high pressure in an air purifier. Background Art

[0002] Air purifiers purify indoor air, generally by filtering, adsorption and other methods, and collect various pollutants in the space, including particulate matter, dust, microorganisms, formaldehyde, volatile organic compounds (TVOC) and other gases, onto the filter. The filter can accommodate these pollutants in the early stage, but as the use time increases, the filter efficiency of the filter decreases, and particulate matter, dust, microorganisms, and gaseous formaldehyde, TVOC and other gases may escape the filter, causing secondary pollution of the indoor air. In general, the number of pollutants that escape is small or negligible, but microorganisms may grow and develop on the filter and cause harmful diffusion. In mild cases, secretions and odors are produced, which are uncomfortable, and in severe cases, it will affect people's health. Therefore, sterilizing the filter inside the air purifier is a rigorous practice.

[0003] Common technologies for sterilizing air purifiers, such as ultraviolet rays, ozone, low-temperature plasma, and chlorine dioxide, all have their own application fields, but they also have their own shortcomings. Ultraviolet rays should be kept away from people. At the same time, ultraviolet rays are used to disinfect and sterilize the surface of objects. The light stops at the irradiated part and cannot take into account the internal space, so only the outer surface is disinfected and sterilized. Ozone can simultaneously disinfect and sterilize the space and the surface. Generally, when the medium is discharged, not only ozone is produced, but also nitrogen oxides are easily produced, which is not conducive to the environment. Low-temperature plasma is relatively easy to disinfect and sterilize the space, but it is difficult to guarantee the effect of disinfecting and sterilizing the filter surface; and there are many low-temperature plasma discharge technologies that will produce a large amount of ozone and nitrogen oxides, which is not what we want. The slow-release chlorine dioxide technology currently on the market basically has no good control over the release rate of chlorine dioxide, and it is difficult to meet the use requirements. If other disinfectants applied to the filter are covered with dust and dust, the subsequent bacteria will not have the opportunity to contact the disinfectant components of the disinfectant and cannot be sterilized.

[0004] Therefore, it is necessary to continue researching and developing sterilization components for air purifiers to achieve rapid, comprehensive and effective sterilization to meet people's usage needs. Utility Model Content

[0008] The sterilization component for air purifier provided by the utility model has the following beneficial effects:

[0009] (1) The sterilization component for the air purifier provided by the utility model utilizes an alternating high-voltage electric field to achieve comprehensive sterilization inside the space and inside the filter, thereby avoiding bacterial growth caused by one-sided sterilization and also avoiding secondary pollution caused by the use of bactericides.

Preferably, a motor vibration damping pad 12 is provided at the connection between the motor 11 and the fan component 9 to reduce the friction between the motor 11 and the fan component 9 during operation.
