Description

Technical Field

[0001] The utility model belongs to the technical field of air purifiers, and in particular relates to a sterilizing air purifier. Background Art

[0002] Air purifiers purify indoor air, usually by filtering and adsorbing, using activated carbon or molecular sieves for gases as adsorbents. After long-term use, microorganisms and bacteria in the air may breed and multiply, producing unpleasant metabolic odors that are difficult to remove and can only be replaced by replacing the filter. In many cases, the filter has not reached its service life, and replacing it to solve the odor problem will undoubtedly increase the user's usage cost.

[0003] Common technologies used to sterilize air purifiers include ultraviolet rays, ozone, low-temperature plasma, chlorine dioxide, etc. 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 the internal space cannot be taken into account, so only the outer surface is disinfected and sterilized. When ozone is produced, generally when the medium discharges, not only ozone is produced, but it is also easily accompanied by the production of nitrogen oxides, which is not conducive to the environment. The effect of low-temperature plasma on the disinfection and sterilization of the filter surface is difficult to guarantee, and it will produce a large amount of ozone and nitrogen oxides, which is not conducive to practical use. The release rate of the slow-release chlorine dioxide technology cannot be controlled, and it is difficult to meet the requirements of use.

[0004] Therefore, it is necessary to continue to research and develop air purifiers that can sterilize themselves, achieve all-round sterilization, improve the sterilization effect, and meet people's usage needs. Utility Model Content

[0005] The utility model provides a sterilizing air purifier, in which a tungsten wire mesh and a filter are arranged inside. The tungsten wire mesh forms a high-voltage electric field to sterilize the internal space of the air purifier and the filter. The single tungsten wire mesh and the filter are arranged alternately to achieve uniform sterilization in the space, greatly improve the sterilization effect, and avoid problems such as obstruction and secondary pollution.

[0006] The utility model provides a sterilizing air purifier, which comprises a tungsten wire mesh, a high-voltage generator and a filter.

[0007] The tungsten wire mesh comprises several layers of single tungsten wire mesh; each layer of single tungsten wire mesh is a tungsten wire arranged in a zigzag shape to form a plane mesh, and the two ends of the tungsten wire are respectively connected to the positive and negative electrodes of the high-voltage generator; several layers of single tungsten wire mesh are arranged in parallel.

[0008] The filter comprises several layers of filter screens, which are arranged alternately with the single tungsten wire screens, and a spacing distance is maintained between the filter screens and the single tungsten wire screens.

[0009] The self-sterilizing air purifier provided by the utility model has the following beneficial effects:

[0010] (1) The sterilizing air purifier provided by the utility model is provided with alternately arranged single tungsten wire meshes and filter screens, which can evenly sterilize the internal space of the air purifier and the filter screen, thereby ensuring the comprehensiveness of the sterilization and effectively preventing the growth and reproduction of microorganisms.

[0011] (2) In the present invention, the tungsten wire mesh is arranged in a space, and there is no need to use a bactericide. Under the premise of ensuring effective and sufficient sterilization, the secondary contamination of the bactericide and other problems can be avoided.

[0012] (3) The self-sterilizing air purifier provided by the utility model can fully sterilize, ensure the service life of the filter, reduce the user's use cost, and meet the use needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be described in detail below through specific implementation modes, and the features and advantages of the present invention will become clearer and more explicit with these descriptions.

[0023] The utility model provides a sterilizing air purifier, which comprises a tungsten wire mesh 1, a high-voltage generator 2 and a filter 3.

[0024] The tungsten wire mesh 1 comprises several layers of single tungsten wire mesh 101; each layer of single tungsten wire mesh 101 is a tungsten wire arranged in a zigzag shape to form a plane mesh, and the two ends of the tungsten wire are respectively connected to the positive and negative electrodes of the high-voltage generator 2; several layers of single tungsten wire mesh 101 are arranged in parallel, as shown in the main view of the structural schematic diagram Figure 1 and Left View Figure 2 The high voltage generator 2 generates a high voltage direct current of 1000V to 20000V, so that the tungsten wire mesh 1 forms a high voltage electric field to sterilize and prevent the growth and reproduction of microorganisms.

[0025] The filter 3 includes several layers of filter screens 301, which are arranged alternately with the single tungsten wire mesh 101, and a distance is maintained between the filter screen 301 and the single tungsten wire mesh 101. The high-voltage electric field formed by the several layers of single tungsten wire mesh 101 can be uniformly radiated to the filter screen 301 for sterilization.

[0026] The self-sterilizing air purifier also includes a housing and a fan assembly. The tungsten wire mesh 1, the high-voltage generator 2 and the filter 3 are placed in the housing. The air inlet is arranged on the outside of the outer filter 301. Under the action of the fan assembly, the incoming air enters against the outer filter 301, passes through the layers of filter 301, and then is discharged for filtering and sterilization. The bottom view of the structural schematic diagram is shown in detail. Figure 3 shown.

[0027] The filter 301 in the filter 3 is selected from a non-charged filter for filtering particulate matter and gaseous pollutants, preferably including a melt-blown filter for filtering particulate matter and / or an activated carbon filter for filtering gaseous pollutants.
