Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a plasma disinfection and sterilization air purification device. Background Technology

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) This utility model sets up a plasma generating module inside the box, and finally releases negative oxygen ions through the plasma generating module to carry out sterilization and disinfection. The plasma excitation technology reproduces the natural air activation process to generate high concentrations of positive and negative ions and a large number of neutral active particles. On the one hand, a large number of positive and negative ions will generate instantaneous high energy during the composite annihilation process, which can effectively kill bacteria and viruses. On the other hand, a large number of active particles can deactivate the necessary substances for microbial metabolism, and because they are electrically neutral, they can spread further, further enhancing the space disinfection and sterilization ability, improving the odor decomposition effect, and also achieving dust reduction effect. This solves the problem of poor indoor air quality caused by the single filter structure and poor disinfection and sterilization effect of existing air purification devices.

[0017] (2) The filter assembly consists of a pre-filter, a filter frame, and an adsorbent material filter element. The pre-filter removes particulate matter and intercepts bacterial and viral aerosols in the air. Then, the adsorbent material filter element removes gaseous pollutants such as odors, improving the odor removal effect and thus improving air quality. The adsorbent material filter element is made of low-volatility flame-retardant material, which has the advantages of being non-toxic, non-polluting, and flame-retardant. It uses ultra-fine glass fiber filter media, hot melt adhesive as a separator, polyurethane two-component sealant, and closed-cell sponge sealing strip. It is made through strict process refinement. The adsorbent material filter element is multi-pleated, which can form a ventilation airflow channel, increase the filter media area and air volume, and reduce air supply resistance.

[0018] (3) By setting an installation component at the rear of the box, the installation component consists of a vertical frame, a top plate, a bottom plate and a fixed horizontal plate. When installing the box, the bottom plate and the top plate move along the positioning column through the adjustment groove to adjust the distance between the vertical frame and the installation wall. The first nut is tightened to fix the box. Multiple fixed horizontal plates are placed in the installation groove. One end of the fastener is threaded through the fastener hole and the moving groove to connect the second nut. The fastener moves up and down along the moving groove to adjust the position of the fixed horizontal plate. Then the second nut is tightened to fix the fixed horizontal plate. By adjusting the number and position of the fixed horizontal plates, the box can be installed in different positions, improving flexibility and applicability. It is suitable for installation and use in different environments. Attached Figure Description

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1, an embodiment of the present invention: a plasma disinfection and sterilization air purification device, comprising: a housing 1, a filter assembly 3 is provided inside the housing 1, a fan 13 is provided on one side of the filter assembly 3, a plasma generating module 2 is provided on one side of the fan 13, the filter assembly 3 includes a pre-filter 8 and an adsorbent material filter element 12, and the adsorbent material filter element 12 is located between the pre-filter 8 and the fan 13, an air inlet 9 is provided on the other side surface of the pre-filter 8, and multiple air inlets 9 are provided, hexagonal bolts 10 are provided at the corners of the pre-filter 8, a filter frame 11 is provided on the outside of the adsorbent material filter element 12, and the adsorbent material filter element 12 is wrapped around the outer edge by the filter frame 11, and the pre-filter 8 is fixed to the filter frame 11 by hexagonal bolts 10. The pre-filter 8 and the filter frame 11 are fixed by hexagonal bolts 10 to form the filter assembly 3, and positioning posts 18 are provided on the upper and lower surfaces of the housing 1, and multiple positioning posts 18 are provided, and a first nut 19 is threadedly connected to the outside of the positioning post 18;

[0029] An air outlet cover 17 is provided on one side of the plasma generating module 2, and the air outlet cover 17 is fixed to the plasma generating module 2 by external bolts. An air outlet 14 is provided on one side surface of the air outlet cover 17, and multiple air outlets 14 are provided, and multiple air outlets 14 all penetrate the air outlet cover 17. A protective back plate 6 is provided at the rear end of the housing 1. A first screw 7 and a second screw 15 are provided at the rear end of the protective back plate 6. The protective back plate 6 is fixed to the housing 1 by the first screw 7, and the protective back plate 6 is fixed to the filter assembly 3, the plasma generating module 2 and the fan 13 by the second screw 15. A power port 16 is provided on the side of the air outlet cover 17 near the bottom, and the power port 16 is fixed to the air outlet cover 17 by external bolts.

[0030] Power is supplied to the plasma generating module 2 and the fan 13 via power port 16. Figure 3 As shown, the fan 13 provides air source for the equipment, and the polluted air is drawn in from the air inlet 9. The pre-filter 8 removes particulate matter and intercepts bacterial and viral aerosols. Then, the air passes through the adsorption material filter element 12 to remove odors and other gaseous pollutants. Finally, the negative oxygen ions are released through the plasma generation module 2 to carry out sterilization and disinfection. The sterilized and disinfected air is discharged from the air outlet 14.

[0031] Plasma disinfection technology is used in the air purification process. Plasma excitation technology reproduces the natural air activation process to generate high concentrations of positive and negative ions and a large number of neutral active particles. On the one hand, a large number of positive and negative ions generate instantaneous high energy during the recombination and annihilation process, which can effectively kill bacteria and viruses. On the other hand, a large number of active particles can deactivate the essential substances for microbial metabolism. Furthermore, because they are electrically neutral, they can spread further, further enhancing the space disinfection and sterilization capabilities and improving safety.

[0032] In terms of odor decomposition, high-energy electrons can break the chemical bonds of harmful gas molecules, causing them to decompose into elemental atoms or harmless molecules. At the same time, active particles can also oxidize and decompose some pollutants into harmless products. In terms of dust suppression, in plasma, electrons, due to their small mass, gain high energy and move rapidly. These high-speed electrons collide with particulate pollutants in the air inelastically, causing electrons to be captured on the surface of the particles and become charged. Particles with different charges attract each other and agglomerate into larger particles, thereby achieving dust suppression.
