Description

Technical Field

[0001] This disclosure relates to the field of plasma technology, and in particular to a self-cleaning plasma generating module and a self-cleaning gas purifier. Background Technology

[0002] Plasma purification technology can be applied to gas purification. This technology uses high-voltage discharge to ionize the air, generating a large number of electrons and ions. The energy generated by the collision and annihilation of these positive and negative ions can decompose germs in the air or on object surfaces, achieving a sterilization effect. Simultaneously, the large number of free radicals such as OH and O generated during the discharge process can further react with harmful organic molecules such as formaldehyde, SO2, and NO2, achieving the purpose of decomposing pollutants. Furthermore, particles with opposite charges in the air attract each other, causing small particles to change into larger particles, thus becoming dust and meeting the dust removal requirements.

[0003] Currently, some of the more advanced gas purification equipment on the market employs plasma purification technology. Existing plasma generators often use needle-shaped, serrated, filamentary, or DBD flat-plate emitting electrodes. After long-term operation, dust easily accumulates on the plasma generating electrodes, significantly reducing their ion release efficiency and consequently decreasing their air purification capacity. Furthermore, since the plasma generator is installed inside the gas purification equipment, cleaning and replacement require shutdown, and the disassembly process is cumbersome.

[0004] As mentioned above, existing gas purifiers have many problems, such as reduced sterilization and dust removal effects after long-term use, decreased efficiency, and inconvenience in disassembly, cleaning, and replacement. Summary of the Invention

[0052] Some embodiments of this disclosure will now be described with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this disclosure, and not all embodiments.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this disclosure, it should be noted that unless otherwise expressly specified and limited, the terms "installation," "connection," and "coupling" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two elements. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0054] Those skilled in the art will understand that the embodiments of this disclosure can be widely applied to various fields. The use of air purification as an example in the description of this disclosure is merely for the purpose of brevity and clarity, and is not intended to limit the embodiments of this disclosure. Conversely, the embodiments of this disclosure can be used in other fields, such as medical devices, cold chain logistics, fresh food processing, etc.

[0055] Figure 1This diagram shows a structural schematic of a self-cleaning plasma generating module 100 according to some embodiments of the present disclosure. Figure 2 A partial structural schematic diagram of an electrode cleaner 140 according to some embodiments of the present disclosure is shown, and Figure 4 A schematic diagram of the structure of the self-cleaning plasma generation module 100 within the electrode cleaner 140 is shown. Figure 1 , 2 As shown in Figure 4, the self-cleaning plasma generating module 100 includes a support column 110, a positive ion emitter 120, a negative ion emitter 130, and an electrode cleaner 140. Figure 4 As shown, the support column 110 has a first surface 111 and a second surface 112. A positive ion emitter 120 is disposed on the first surface 111 of the support column 110 and can be used to release positive ions. A negative ion emitter 130 is disposed on the second surface 112 of the support column 110 and can be used to release negative ions.

[0056] The electrode cleaner 140 may include a bracket 141 and an electrode wiping pad 142. The bracket 141 is disposed outside the support column 110 and can be used to drive the electrode wiping pad 142 to rotate around the support column 110. The electrode wiping pad 142 is disposed inside the bracket 141 and moves under the drive of the bracket 141 to clean the positive ion emitter 120 and / or the negative ion emitter 130. In some embodiments, the electrode wiping pad 142 may include an insulating material sheet or insulating material block, such as a plastic sheet, plastic block, rubber sheet or rubber block, etc.

[0057] The support 141 may include a perforated cylindrical body adapted to the support column 110. Electrode wiping pads 142 may be arranged in a staggered, parallel, or dispersed manner within the perforated cylindrical body. For example, as... Figure 2 As shown, the electrode wiping pads 142 are staggered within the hollow cylinder, allowing them to clean the electrodes of the positive ion emitter 120 and / or the negative ion emitter 130 alternately as the hollow cylinder rotates. The six electrode wiping pads 142 are positioned at different heights on the bracket 141 and are not aligned in a straight line. Each electrode wiping pad 142 corresponds to a positive ion emitter 120 and / or negative ion emitter 130 at the same height. This ensures that when the bracket 141 moves the electrode wiping pads 142 to clean the electrodes of the ion emitters, at least one electrode remains operational. This prevents the electrode wiping pads 142 from excessively affecting the ion generation efficiency of the self-cleaning plasma generation module 100, thus avoiding a weakening of the air purification effect.

[0058] Those skilled in the art will understand that, although Figure 1The bracket 141 shown is a hollow cylindrical body with a rectangular longitudinal section and a circular cross-section, and the hollow shape is polygonal. However, the bracket 141 can also be a hollow cylindrical body with a trapezoidal or triangular longitudinal section, and the cross-section can be polygonal. The hollow shape can be one or more of the following: triangular, circular, rectangular, rhomboid, polygonal, or irregular shapes. Those skilled in the art will understand that although... Figure 2 The number of electrode wiping pads 142 shown is 6, but the number of electrode wiping pads may be less than 6 or more than 6.

[0059] In some embodiments, such as Figure 4 As shown, the electrode cleaner 140 also includes a rotating base 143. The rotating base 143 includes a base 1431 and a rotating ring 1432 sleeved around the base 1431. The bracket 141 can be detachably mounted (e.g., by means of a fixing screw 1411, such as...). Figure 1 (As shown) It is fixed on the rotating ring 1432 and can rotate with the rotating ring 1432.

[0060] Those skilled in the art will understand that, although Figure 1 The bracket 141 is fixed to the rotating ring 1432 by fixing screws 1411. However, the bracket 141 can also be fixed to the rotating ring 1432 by magnetic coupling, snap-fit, adhesive or other fixing methods, or be integrally formed with the rotating ring 1432.

[0061] Figure 3 A partial structural bottom view of a self-cleaning plasma generating module according to other embodiments of this disclosure is shown. Figure 3 As shown, in some embodiments, the electrode cleaner 140 further includes a drive motor 144 and a transmission component 145. The transmission component 145 can be a transmission gear set, which includes a driving gear 1451 and a driven gear 1452. The driving gear 1451 is fixed to the output end of the drive motor and meshes with the driven gear 1452. The driven gear 1452 is fixed to the rotating ring 1432. The drive motor 144 drives the driving gear 1451 to rotate, thereby causing the driven gear 1452 to rotate, which in turn causes the rotating ring 1432 to rotate.

[0062] Those skilled in the art will understand that, although Figure 1 The transmission component 145 shown is a transmission gear set. The transmission method of the transmission component 145 is gear transmission, but the transmission method of the transmission component 145 can also be any one of belt transmission, chain transmission, worm gear transmission or screw transmission.

[0063] In other embodiments, the transmission element may also be a transmission rod. The two ends of the transmission rod are hinged to the output end of the drive motor 144 and the rotating ring 1432, respectively, and can be used to drive the rotating ring 1432 to rotate under the drive of the drive motor 144.

[0064] The drive motor 144 can be a stepper motor, having an output end capable of rotating around its own axis. The drive wheel 1451 can drive the rotating ring 1432 to rotate reciprocally according to a predetermined number of steps from the drive motor 144. Those skilled in the art will understand that the rotation and stopping of the drive wheel 1451 can also be controlled by turning the drive motor 144 on and off.

[0065] Figure 4 A partial front view of a self-cleaning plasma generating module 100 according to some embodiments of the present disclosure is shown; Figure 5 A partial top view of a self-cleaning plasma generating module 100 according to some embodiments of the present disclosure is shown.

[0066] like Figure 4 , 5 As shown, the support column 110 is a cuboid column structure, with the first surface 111 and the second surface 112 arranged opposite to each other.

[0067] Those skilled in the art will understand that, although Figure 4 , Figure 5 The support column 110 shown is a cuboid column structure, but the support column 110 can also be at least one of elliptical column, cylindrical, and prismatic.

[0068] Those skilled in the art will understand that, although Figure 4 , Figure 5 Only the first surface 111 and the second surface 112 are shown facing away from each other, but the first surface 111 and the second surface 112 may also be angled or connected to form a closed curved surface. Those skilled in the art will understand that, although... Figure 4 , Figure 5 Only the positive ion emitter 120 and negative ion emitter 130 arranged in a linear pattern are shown, but the positive ion emitter 120 and negative ion emitter 130 may also be arranged in one or more of the following: arc-shaped, zigzag-shaped, rectangular, circular, or polygonal patterns.

[0069] In some embodiments, the positive ion emitter 120 and the negative ion emitter 130 include clusters of micro / nano conductive fibers, which include at least one of the following: carbon fiber, graphite fiber, metal fiber, glass fiber, ceramic fiber, short tungsten filament, polypropylene or polyethylene filaments doped with carbon fiber; the number of micro / nano fibers is in the range of 1,000 to 100,000; or the diameter is in the range of 10 nanometers to 100 micrometers. Micro / nano conductive fiber sheets made of different numbers of conductive fibers have different areal densities. The more fibers there are, the smaller the diameter of the conductive fibers, the shorter the length, and the more conductive fiber ends per unit area, i.e., the more discharge tips on the plane, the higher the plasma emission efficiency.

[0070] During use, dust or other impurities easily accumulate on the tips of the micro-nano conductive fiber clusters of the positive ion emitter 120 and negative ion emitter 130, affecting ion generation efficiency. The electrode cleaning pad 142 of the electrode cleaner 140, driven by the movement (e.g., rotation) of the support 141, sweeps across the tips of the micro-nano conductive fiber clusters of the positive ion emitter 120 and negative ion emitter 130, thereby cleaning the discharge tips, removing dust or other impurities, greatly improving ion generation efficiency, and significantly extending the service life of the ion emitter.

[0071] In some embodiments, the self-cleaning plasma generating module 100 further includes a high-voltage transformer 150. The positive ion emitter 120 and the negative ion emitter 130 are connected to the high-voltage transformer 150 via leads, and the high-voltage transformer 150 can be used to supply power to the positive ion emitter 120 and the negative ion emitter 130. When the positive ion emitter 120 and the negative ion emitter 130 are connected to a high-voltage power supply, the micro / nano conductive fiber sheets discharge through a large number of fiber tips, ensuring sufficient discharge channels and thus stably releasing high-concentration plasma.

[0072] Those skilled in the art will understand that, although Figure 1 Only the high-voltage transformer 150 is shown, but the positive ion emitter 120 and the negative ion emitter 130 can also be connected to a power interface or power source to power the positive ion emitter 120 and the negative ion emitter 130, or they can be connected to a rechargeable battery for power supply.

[0073] Figure 6 A schematic diagram of the structure of a self-cleaning plasma generating module 600 according to other embodiments of the present disclosure is shown; Figure 7 A cross-sectional view of an electrode cleaner 641 according to other embodiments of the present disclosure is shown.

[0074] like Figure 6 , 7 As shown, in some other embodiments, the bracket 641 of the self-cleaning plasma generating module 600 has a rectangular cutout shape and is evenly divided into six layers from top to bottom. Each layer is provided with an electrode wiping plate 642. The six electrode wiping plates 642 are not located on the same line, so that when the bracket 641 moves the electrode wiping plates 642 to clean the electrodes of the ion emitter, there are always electrodes in the working state. This avoids the electrode wiping plates 642 from excessively affecting the ion generation efficiency of the self-cleaning plasma generating module 600, thereby avoiding a weakening of the air purification effect.

[0075] The self-cleaning plasma generating module 600 has a toothed outer ring 6432, and a gear-driven wheel 645 is located on the output end of the drive motor 644 and meshes with the outer teeth of the rotating ring 6432. The drive motor 644 drives the drive wheel 645 to rotate, thereby causing the rotating ring 6432 to rotate, which in turn causes the support 641 to rotate, thus cleaning the electrodes of the ion emitter in real time.

[0076] Figure 8 A self-cleaning gas purifier 1000 according to some embodiments of the present disclosure is shown. For example... Figure 8 As shown, the self-cleaning gas purifier 1000 includes a self-cleaning plasma generating module 100 (or a self-cleaning plasma generating module 600), a purifier housing 200, and an airflow driving device 300. The purifier housing 200 has an airflow inlet 201 and an airflow outlet 202. The airflow driving device 300 can be used to drive airflow from the airflow inlet 201 into the purifier housing 200, through the self-cleaning plasma generating module 100, and out of the purifier housing 200 from the airflow outlet 202, thereby forming a plasma processing area within the purifier housing 200.

[0077] Those skilled in the art will understand that, although Figure 8 Only the cylindrical purifier housing 200 is shown in the image, but the purifier housing 200 may also be at least one of the following: elliptical cylinder, cuboid cylinder, and prism.

[0078] In some embodiments, the airflow inlet 201 of the purifier housing 200 is disposed along the side of the purifier housing 200. For example, the airflow inlet 201 can be disposed at the lower part of the purifier housing 200, and the airflow outlet 202 can be disposed at the top of the purifier housing 200, so that the airflow can form a bottom-up circulation and fully contact the plasma generating module. The positive and negative ion emitters are arranged opposite to each other to reduce the probability of premature recombination of positive and negative ions, thereby resulting in a higher concentration of positive and negative ions in the airflow and better sterilization and dust removal effects.

[0079] In some embodiments, the self-cleaning plasma generating module 100 is detachably fixed to the center of the bottom of the purifier housing 200 by bolts. An airflow driving device 300 is positioned above the self-cleaning plasma generating module 100 to form an annular plasma treatment zone around it. The airflow driving device 300 includes a turbine fan, which causes the intake airflow to pass through the plasma treatment zone in a rotating path, extending the residence time of the gas within the plasma treatment zone and promoting the mixing of gas with positive / negative ions. This increases the probability of pathogen particles adsorbing positive / negative ions or colliding with them, achieving better sterilization and purification effects. The self-cleaning plasma generating module 100 is detachably fixed to the center of the bottom of the purifier housing 200, making it easy to install, remove, and replace during maintenance.

[0080] In some embodiments, the self-cleaning gas purifier 1000 further includes a filter 400. The filter 400 is disposed at the airflow inlet 201 of the purifier housing 200, and the filter 400 can be one or more of a pre-filter, a medium-efficiency filter, and a high-efficiency filter.

[0081] Those skilled in the art will understand that, although Figure 8 Only one filter 400 is shown, but multiple or multi-layered filters can be installed at the airflow inlet 201, such as a combination of primary and secondary filters, or a combination of primary, medium and high efficiency filters.

[0082] Because suspended particulate matter in the air attracts each other by adsorbing positive and negative ions, small particles aggregate into larger particles. Therefore, this disclosure uses a filter 400 and a self-cleaning plasma generating module 100 together, which can effectively improve the interception efficiency of the filter 400, achieving rapid air purification. The filtration level of the filter 400 can be reduced without affecting the filtration effect, reducing airflow loss, lowering turbine fan energy consumption, and promoting energy conservation and environmental protection. To further improve the filtration effect, multiple filters can be used in combination as needed. Furthermore, placing the filter 400 at the airflow inlet 201 can also reduce the degree of dust contamination on the electrodes of the self-cleaning plasma generating module 100, reducing the workload of the electrode cleaner 140, extending equipment lifespan, and lowering equipment costs. However, those skilled in the art will understand that the filter 400 can also be placed at the airflow outlet 202.

[0083] Although Figure 8 The filter 400 shown is generally annular or partially annular, but those skilled in the art will understand that the filter 400 can also take any other suitable shape, and can also take a suitable shape according to the shape and arrangement of the purifier housing 200 or the self-cleaning plasma generating module 100.

[0084] When the turbine fan and the self-cleaning plasma generator module 100 operate simultaneously, the self-cleaning plasma generator module 100 generates a large number of positive and negative ions, forming a high-concentration plasma treatment zone. Airflow is drawn into the purifier housing 200 through the airflow inlet 201. Some airborne particles and the germs they carry are intercepted by the filter 400. Uninterrupted germs are efficiently killed by the high concentration of positive and negative ions in the plasma treatment zone. The airflow is then discharged through the airflow outlet 202. The repeated circulation of airflow through the plasma treatment zone achieves the effect of sterilizing indoor air.

[0085] Furthermore, 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 airflow passing through the plasma treatment zone, sterilizing the gases and viruses present on object surfaces in the external space. In addition, these positive and negative ions diffused into the external space will also be drawn back into the purifier housing 200 by the airflow and adsorbed onto the filter 400, further killing bacteria intercepted by the filter 400, preventing bacteria from growing on the filter 400, and eliminating secondary pollution caused by a contaminated filter 400.

[0086] It should be noted that the above are merely preferred embodiments of this disclosure and are not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
