Fig. 1 illustrates a schematic structural view of a self-cleaning plasma generation module 100 according to some embodiments of the present disclosure, fig. 2 illustrates a schematic structural view of a portion of an electrode cleaner 140 according to some embodiments of the present disclosure, and fig. 4 illustrates a schematic structural view of the self-cleaning plasma generation module 100 within the electrode cleaner 140. As shown in fig. 1, 2 and 4, the self-cleaning plasma generating module 100 includes a support column 110, a positive ion discharger 120, a negative ion discharger 130 and an electrode cleaner 140.

In some embodiments, the electrode wiping sheet 142 may comprise a sheet or block of insulating material, such as a sheet, block, rubber sheet or block, or the like.

The support 141 may comprise a hollow cylinder adapted to the support column 110. The electrode wiping sheets 142 may be staggered, juxtaposed, or dispersed within the hollow cylinder.

As shown in fig. 3, in some embodiments, electrode cleaner 140 further includes a drive motor 144 and a transmission 145. The transmission 145 can be a drive gear set that includes a drive gear 1451 and a driven gear 1452. The driving pulley 1451 is fixed to an output end of the driving motor and engaged with the driven pulley 1452. The driven wheel 1452 is fixed to the rotating ring 1432. The driving motor 144 drives the driving wheel 1451 to rotate, so as to drive the driven wheel 1452 to rotate, and then the rotating ring 1432 is rotated.

As shown in fig. 4 and 5, the supporting column 110 has a rectangular parallelepiped columnar structure, and the first surface 111 and the second surface 112 are disposed opposite to each other.

It will be understood by those skilled in the art that although fig. 4 and 5 only show the first surface 111 and the second surface 112 disposed opposite to each other, the first surface 111 and the second surface 112 may be disposed at an angle or connected to form a closed curved surface. It will be understood by those skilled in the art that although fig. 4 and 5 show only the positive ion releaser 120 and the negative ion releaser 130 in a linear arrangement, the positive ion releaser 120 and the negative ion releaser 130 may be in one or more of an arc-shaped arrangement, a zigzag-shaped arrangement, a rectangular arrangement, a circular arrangement, and a polygonal arrangement.

In some embodiments, the positive ion releaser 120 and the negative ion releaser 130 comprise micro-nano conductive fiber clusters comprising at least one of: one or more of carbon fiber, graphite fiber, metal fiber, glass fiber, ceramic fiber, short tungsten filament, polypropylene or polyethylene filament doped with carbon fiber; micro-nano fibers with the number within the range of 1000-; or micro-nanofibers having a diameter in the range of 10 nanometers to 100 micrometers. The micro-nano conductive fiber sheets made of the conductive fibers with different numbers have different surface densities, the more the number of the fibers is, the smaller the diameter of the conductive fibers is, the shorter the length of the conductive fibers is, the more the tail ends of the conductive fibers in unit area are, namely, the more the discharge tips on the plane are, and the higher the plasma emission efficiency is.

In the using process, dust or other impurities are easily deposited at the tips of the micro-nano conductive fiber clusters of the positive ion releaser 120 and the negative ion releaser 130, and the ion generating efficiency is affected. The electrode wiping sheet 142 of the electrode cleaner 140 can sweep the tips of the micro-nano conductive fiber clusters of the positive ion releaser 120 and the negative ion releaser 130 under the driving of the movement (e.g., rotation) of the bracket 141, so as to clean the discharge tips, sweep away dust or other impurities, greatly improve the ion generation efficiency, and significantly prolong the service life of the ion releaser.

In some embodiments, the self-cleaning plasma generation module 100 further includes a high voltage transformer 150. The positive ion releaser 120 and the negative ion releaser 130 are connected to a high voltage transformer 150 through lead wires, and the high voltage transformer 150 may be used to supply power to the positive ion releaser 120 and the negative ion releaser 130. When the positive ion releaser 120 and the negative ion releaser 130 are connected with a high-voltage power supply, the micro-nano conductive fiber sheet discharges through a large number of fiber tips, so that a sufficient discharge channel can be ensured, and high-concentration plasma can be stably released.

It will be understood by those skilled in the art that although only the high voltage transformer 150 is shown in fig. 1, the positive ion discharger 120 and the negative ion discharger 130 may be connected to a power interface or a power source to supply power to the positive ion discharger 120 and the negative ion discharger 130, or may be connected to a rechargeable battery to supply power.

FIG. 6 illustrates a schematic structural diagram of a self-cleaning plasma generation module 600 according to further embodiments of the present disclosure; fig. 7 illustrates a cross-sectional view of an electrode cleaner 641 according to further embodiments of the present disclosure.

As shown in fig. 6 and 7, in other embodiments, the hollow-out shape of the support 641 of the self-cleaning plasma generation module 600 is rectangular, and the support 641 is divided into six layers from top to bottom, each layer is provided with one electrode wiping sheet 642, and the six electrode wiping sheets 642 are not located on the same line, so that when the support 641 drives the electrode wiping sheets 642 to move to clean the electrodes of the ion releaser, the electrodes are always kept in a working state, and the ion generation efficiency of the self-cleaning plasma generation module 600 is prevented from being excessively affected by the electrode wiping sheets 642, thereby preventing the air purification effect from being weakened.

Fig. 8 illustrates a self-cleaning gas purifier 1000 according to some embodiments of the present disclosure. As shown in fig. 8, the self-cleaning gas purifier 1000 includes a self-cleaning plasma generation module 100 (or a self-cleaning plasma generation module 600), a purifier housing 200, and a gas flow driving device 300. The purifier housing 200 has an airflow inlet 201 and an airflow outlet 202. The gas flow driving device 300 may be used to drive a gas flow from the gas flow inlet 201 into the purifier housing 200 through the self-cleaning plasma generation module 100 and from the gas flow outlet 202 out of the purifier housing 200 such that a plasma processing region is formed within the purifier housing 200.

It will be understood by those skilled in the art that although only the cylindrical purifier housing 200 is illustrated in fig. 8, the purifier housing 200 may be at least one of an elliptic cylinder, a rectangular parallelepiped cylinder, and a prism.

In some embodiments, the gas flow inlet 201 of the purifier housing 200 is disposed along a side of the purifier housing 200. For example, the gas flow inlet 201 may be disposed at a lower portion of the purifier housing 200, and the gas flow outlet 202 may be disposed at a top portion of the purifier housing 200, so that the gas flow can form a bottom-to-top circulation, which is sufficiently in contact with the plasma generation module. The positive and negative ion releasers are arranged back to back, so that the probability of positive and negative ions compounding in advance is reduced, the concentration of positive and negative ions in the air flow is higher, and the degerming and dust removal effects are better.

In some embodiments, the self-cleaning plasma generation module 100 is detachably fixed at the center of the bottom of the purifier housing 200 by bolts, and the air flow driving device 300 is disposed above the self-cleaning plasma generation module 100 to form an annular plasma treatment region around the self-cleaning plasma generation module 100. The airflow driving device 300 includes a turbo fan, which makes the sucked airflow pass through the plasma processing region in a rotating path, prolongs the retention time of the gas in the plasma processing region, promotes the mixing of the gas and the positive/negative ions, improves the probability of the pathogen particles adsorbing the positive/negative ions or colliding with the positive/negative ions, and achieves better sterilization and purification effects. The self-cleaning plasma generation module 100 is detachably fixed at the center of the bottom of the purifier housing 200, and is convenient to disassemble and assemble and convenient to overhaul and replace.

In some embodiments, self-cleaning gas purifier 1000 further comprises a screen 400. The screen 400 is disposed at the airflow inlet 201 of the purifier housing 200, and the screen 400 may be one or more of a primary screen, a middle screen, and a high-efficiency screen.

It will be appreciated by those skilled in the art that although only one screen 400 is shown in fig. 8, multiple or multi-layered screens, such as primary and intermediate effect screens, or primary, intermediate and high effect screens, may be installed at the airflow inlet 201.

Because the suspended particles in the air can be mutually attracted by respectively adsorbing positive and negative ions, the particles are gathered into large particles. Therefore, the filter screen 400 and the self-cleaning plasma generation module 100 are matched for use, the intercepting efficiency of the filter screen 400 can be effectively improved, the effect of quickly purifying air is achieved, the filtering grade of the used filter screen 400 can be reduced on the premise that the filtering effect is not influenced, the air quantity loss is reduced, the energy consumption of the turbofan is reduced, and the self-cleaning plasma generation module is energy-saving and environment-friendly. In order to further improve the filtering effect, a plurality of filter screens can be combined according to actual needs. Moreover, the filter screen 400 is disposed at the airflow inlet 201, so that the degree of dust pollution of the electrode of the self-cleaning plasma generation module 100 can be reduced, the working strength of the electrode cleaner 140 can be reduced, the service life of the equipment can be prolonged, and the equipment cost can be reduced. However, it will be appreciated by those skilled in the art that the screen 400 may also be disposed at the airflow outlet 202.

Although fig. 8 illustrates the screen 400 as being substantially annular or partially annular, it will be appreciated by those skilled in the art that the screen 400 may take any other suitable shape, and may take any suitable shape depending on the shape and arrangement of the purifier housing 200 or the self-cleaning plasma generation module 100.

When the turbofan and the self-cleaning plasma generating module 100 are simultaneously operated, the self-cleaning plasma generating module 100 generates a large amount of positive and negative ions to form a high concentration plasma processing region. The air flow is sucked into the purifier shell 200 through the air flow inlet 201, particulate matters in part of the air and germs carried by the particulate matters are intercepted by the filter screen 400, the germs which are not intercepted are efficiently killed under the action of high-concentration positive and negative ions in the plasma treatment area, and then the germs are discharged through the air flow outlet 202, and the air flow can achieve the effect of sterilizing the indoor air after circulating through the plasma treatment area for multiple times.

In addition, the high concentration of positive and negative ions generated by the self-cleaning plasma generating module 100 can also diffuse into the external space of the self-cleaning gas purifier 1000 along with the gas flow passing through the plasma processing region, and can sterilize the gas in the external space and viruses existing on the surface of the object. In addition, the positive and negative ions diffused to the external space are sucked into the purifier housing 200 again along with the airflow and adsorbed onto the filter screen 400, so that germs intercepted by the filter screen 400 can be killed again, the germs are prevented from breeding on the filter screen 400, and the secondary pollution phenomenon caused by the polluted filter screen 400 is avoided.

It should be understood that the above-mentioned embodiments are merely preferred embodiments of the present disclosure, and are not intended to limit the present disclosure, so that any modification, equivalent replacement, or improvement made within the spirit and principle of the present disclosure should be included in the scope of protection of the present disclosure.
