Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and particularly to a filtering device for dispersed particles in the air. Background Art

[0002] In modern society, the air quality problem is becoming increasingly serious. Especially against the backdrop of the accelerating urbanization process, the concentration of dispersed particles in the air is constantly rising. These dispersed particles include dust, pollen, bacteria, viruses, and other harmful substances. Long-term exposure to such an environment may pose a threat to human health. Therefore, the research and development of air filtration technology are particularly important.

[0003] Against this backdrop, air filters, as important devices for improving indoor and outdoor air quality, are widely used in multiple fields such as homes, workplaces, and industrial production. Existing air filtration technologies mainly include mechanical filtration, electrostatic adsorption, activated carbon adsorption, etc. These technologies use different principles and materials to strive to remove harmful substances in the air while maintaining good air circulation. However, although these technologies are effective to a certain extent, there are still some limitations.

[0004] Firstly, traditional mechanical filters often have insufficient filtration efficiency when dealing with tiny particles. Many filters are not designed with full consideration of the characteristics of different particles, resulting in a significant decline in filtration effect in a high-concentration pollution environment. In addition, although electrostatic adsorption technology can improve the capture rate of certain particles, its effect will also be affected in a high-humidity or dusty environment, leading to unstable performance of the filter.

[0005] Secondly, during the use of existing air filtration equipment, frequent maintenance and replacement are often required. After long-term use, a large amount of dust and pollutants will accumulate on the surface of traditional filters, resulting in an increase in resistance and obstruction of air circulation. Users need to clean or replace the filter regularly, which not only increases the maintenance cost but also brings inconvenience to users. Especially in a commercial environment, frequent maintenance may affect normal operation.

[0006] In addition, existing technologies generally lack an effective self-cleaning mechanism. During the cleaning process, secondary pollution often occurs, that is, dust and harmful substances attached to the filter are released during cleaning, affecting air quality.

[0025] The following refers to Figures 1 to 8 Describe the filtering device for airborne dispersed particles provided by the embodiments of the present invention.

[0026] As Figures 1 to 3 shown, the filtering device for airborne dispersed particles provided by the embodiments of the present invention is particularly suitable for filtering indoor and outdoor air. Of course, it can also be applied to air filtration treatment under other operating conditions.

[0027] Specifically, the filtering device for airborne dispersed particles includes a main housing 100. The main housing 100 serves as the installation base for other components, and other components can be directly or indirectly installed within the main housing 100 and form a relative whole after installation. As Figure 1 shown, the outer shape of the main housing 100 is in the shape of a cuboid.

[0028] The main housing 100 includes an upper housing 110, a connecting housing 120, and a lower housing 130. Among them, the connecting housing 120 is fixedly connected to the upper housing 110, and the connecting housing 120 is detachably connected to the lower housing 130. An operation panel 111 is provided on the upper housing 110 for directly controlling the start and stop of filtration.

[0029] An elastic filter layer 300 is provided inside the lower housing 130. The lower end of the elastic filter layer 300 is detachably connected to the lower housing 130 and is arranged in the vertical direction. During operation, the two are fixed by other means such as fixing components. When it is necessary to replace or clean the elastic filter layer 300, first detach the connecting housing 120 from the lower housing 130, then detach the lower housing 130 from the elastic filter layer 300, and then remove the lower housing 130 to take out the elastic filter layer 300.

[0030] Specifically, the elastic filter layer 300 is in a cylindrical structure. The cylindrical structure has a first axis, and its outer wall is a periodically undulating structure.

[0031] As Figure 6As shown, the periodic undulating structure includes a plurality of raised areas 302 and a plurality of recessed areas 303 that are alternately connected in sequence around the first axis. Specifically, when the air is filtered through the elastic filter layer 300, the raised areas 302 produce a diversion effect on the airflow, forcing impurities to migrate to adjacent recessed areas 303, so that the impurities in the air are concentrated in the recessed areas 303 of the elastic filter layer 300, and the impurities in the raised areas 302 are less. Therefore, it is effectively avoided that the impurities are evenly distributed on the entire surface of the elastic filter layer 300, thereby preventing the clogging of many filter holes and maintaining the filtering efficiency.

[0032] When the vibration cleaning mechanism 200 drives the elastic filter layer 300 to deform, the depression degree of the depressed area 303 will increase. When the elastic filter layer 300 loses the external driving force, the elastic filter layer 300 resets and rebounds, and the depression degree of the depressed area 303 rebounds to the initial state. The depression degree change process of the depressed area 303 is the specific embodiment of the periodic deformation of the elastic filter layer 300. Therefore, during the reset and rebound of the elastic filter layer 300, the impurities lag behind the movement of the elastic filter layer 300 due to inertia and are forced to leave the depressed area 303. And during the reset and rebound process, the elastic filter layer 300 vibrates due to its own elastic characteristics, further causing the impurities to fall off the surface of the elastic filter layer 300.

[0033] In addition, the vibration cleaning mechanism 200 has a direct contact portion and a non-contact portion with the elastic filter layer 300. When the vibration cleaning mechanism 200 is started, the direct contact portion of the vibration cleaning mechanism 200 contacts the elastic filter layer 300. Since the lower end of the elastic filter layer 300 is connected to the lower shell 130 through a fixing assembly, the vibration cleaning mechanism 200 drives the elastic filter layer 300 to twist relative to the lower shell 130, causing the entire elastic filter layer 300 to deform.

[0034] When the direct contact part of the vibration cleaning mechanism 200 rotates to the non-contact part, the vibration cleaning mechanism 200 loses contact with the elastic filter layer 300, and the elastic filter layer 300 loses external driving force. At this time, the elastic filter layer 300 is reset to its original position with the help of its own elastic properties, and its wavy structure gradually rebounds to its original shape. Because the impurities lag behind the movement of the elastic filter layer 300 due to inertia, the impurities are forced to leave the surface of the elastic filter layer 300. At the same time, during the reset and rebound process, the elastic filter layer 300 vibrates due to its own elastic properties, further causing the impurities to fall off the surface of the elastic filter layer 300. In this process, since the lower end of the elastic filter layer 300 is connected to the lower shell 130 through a fixed component, and the elastic properties have a delay, the reset process is carried out from the top of the elastic filter layer 300 to the bottom, that is, Figure 6in the up-down direction. Therefore, the entire elastic filter layer 300 vibrates step by step from top to bottom, further enhancing the vibration effect of the entire filter layer, and thus more effectively shedding the impurities on the surface of the elastic filter layer 300.

[0035] Since the vibration cleaning mechanism 200 continuously drives the elastic filter layer 300, the directly contacting part and the non-contacting part thereof also continuously alternate contact with the elastic filter layer 300, causing the elastic filter layer 300 to be in a cyclic state of deformation and rebound reset, and thus enabling the elastic filter layer 300 to form periodic deformation. Thereby, the elastic filter layer 300 continuously performs impurity cleaning with periodic deformation, enhancing the self-cleaning ability of the device, prolonging the service time of the elastic filter layer 300, and improving the overall filtration efficiency.

[0036] In one embodiment, as Figure 6 shown, both the convex region 302 and the concave region 303 are in an arc shape, and the central positions of the arc shapes of the two are located inside and outside the elastic filter layer 300 respectively, forming an arc-shaped wavy structure. The convex region 302 and the concave region 303 of this arc-shaped wavy structure are connected by an arc transition. Compared with the existing smooth surface cylinder shape, its outer peripheral wall is a smooth curved surface, increasing the filtration area of the elastic filter layer 300, and thus being able to filter out more impurities. At the same time, the elastic filter layer 300 with an arc-shaped wavy structure can effectively push the impurities to the concave region 303, preventing the impurities from covering the entire elastic filter layer 300, and further preventing clogging of more filter holes and maintaining the filtration efficiency.

[0037] It can be understood that the convex region 302 and the concave region 303 can also be serrated, and the openings of the serrations of the two face the inside and outside of the elastic filter layer 300 respectively, forming a toothed wavy structure. The convex region 302 and the concave region 303 of this toothed wavy structure are connected by a straight surface. Although the design of the straight surface can better accumulate impurities in the concave region 303 compared with the design of the arc surface, the design of the arc surface makes the deformation and rebound vibration of the elastic filter layer 300 more smooth and continuous.

[0038] Therefore, the choice between the wavy structure and the toothed wavy structure needs to be weighed according to specific filtration requirements and cleaning efficiency.

[0039] In one embodiment, as Figure 5 and Figure 6 shown, the vibration cleaning mechanism 200 includes an intermittent meshing structure. Specifically, the vibration cleaning mechanism 200 further includes a driving motor 210 for providing power to the intermittent meshing structure. As Figures 5 to 8 shown, a mating gear ring 301 is provided at the edge of the elastic filter layer 300, and the mating gear ring 301 cooperates with the intermittent meshing structure.

[0040] In one embodiment, the intermittent meshing structure is an incomplete gear 220. Further, as Figure 8 shown, a part of the incomplete gear 220 is a toothed section 221 and a part is a toothless section 222, wherein the toothed section 221 corresponds to the direct contact part of the vibration cleaning mechanism 200, and the toothless section 222 corresponds to the non-contact part. When the driving motor 210 drives the incomplete gear 220 to rotate, its toothed section 221 rotates in cooperation with the mating gear ring 301, causing the elastic filter layer 300 to twist and then deform. When the toothed section 221 switches to the toothless section 222, the incomplete gear 220 disengages from the mating gear ring 301, and the elastic filter layer 300 loses the external driving force and resets to its original position, and its wavy structure gradually rebounds to the initial state. During the reset and rebound process, the elastic filter layer 300 vibrates due to its own elastic characteristics, effectively promoting the detachment of impurities attached to its surface.

[0041] Therefore, when the driving motor 210 continuously drives the incomplete gear 220 to rotate, the alternating contact of its toothed section 221 and toothless section 222 with the mating gear ring 301 causes the elastic filter layer 300 to continuously alternate contact with the toothed section 221 or the toothless section 222. The incomplete gear 220 realizes the intermittent driving of the elastic filter layer 300, forming a periodic power output to the elastic filter layer 300, making the elastic filter layer 300 in a cyclic state of deformation and rebound reset, and then forming a periodic deformation.

[0042] In one embodiment, the filtration device for dispersed particles in the air further includes a multi-layer auxiliary filtration structure.

[0043] Further, the multi-layer auxiliary filtration structure includes a primary filter screen 410, a fine filter screen 420, and an adsorption layer 430. As Figure 6 shown, the primary filter screen 410 is arranged inside the elastic filter layer 300, the fine filter screen 420 is arranged inside the primary filter screen 410, and the adsorption layer 430 is arranged inside the fine filter screen 420. Specifically, the aperture of the filtration holes on the fine filter screen 420 is smaller than the aperture of the filtration holes on the primary filter screen 410. Furthermore, the primary filter screen 410 is used to further filter larger particles in the air, and the fine filter screen 420 is used to filter smaller impurities in the air. The adsorption layer 430 used in the present invention is activated carbon, which is used for deodorization and odor removal. It can be understood that the adsorption layer 430 can also include other common adsorption layers 430, such as activated oxygen technology, diatom mud, etc., as long as the above technical effects are achieved, they can be applied to the present invention.

[0044] The primary filter screen 410 has the same shape as the elastic filter layer 300 and the two are closely arranged. Therefore, when the elastic filter layer 300 deforms, it will force the primary filter screen 410 to vibrate, and then the impurities attached to the primary filter screen 410 can be removed by vibration.

[0045] In one embodiment, as Figure 4 shown, the multi-layer auxiliary filtration structure further includes an ultraviolet sterilization lamp 440. The ultraviolet sterilization lamp 440 is disposed inside the adsorption layer 430 along the first axis and is directly controlled by the control panel for disinfection and sterilization.

[0046] In one embodiment, as Figure 1 and Figure 2 shown, the filtration device for airborne particulate matter further includes a plurality of air inlets 131 and a plurality of air outlets 113. The air inlets 131 are provided on the lower housing 130 for introducing the air to be filtered; the air outlets 113 are provided on the upper housing 110 for discharging the filtered air into the external environment.

[0047] In one embodiment, as Figure 4 and Figure 5 shown, the filtration device for airborne particulate matter further includes an air extraction mechanism 112. The air extraction mechanism 112 is disposed inside the upper housing 110 and is connected to the air outlet 113. Specifically, the air extraction mechanism 112 draws the air to be filtered into the device through the air inlets 131 on the lower housing 130. The air first passes through the elastic filtration layer 300 for preliminary filtration, and then sequentially passes through the primary filter screen 410, the fine filter screen 420 and the adsorption layer 430 for further in-depth filtration treatment. Finally, after being sterilized by the ultraviolet sterilization lamp 440, the purified air is discharged into the external environment through the air outlet 113.

[0048] In one embodiment, as Figure 4 and Figure 5 shown, the filtration device for airborne particulate matter further includes a connecting plate 121. Specifically, the connecting plate 121 is disposed on the connecting housing 120, and a plurality of vibration cleaning mechanisms 200 are disposed on both sides of the connecting plate 121.

[0049] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0050] The above-described embodiments merely represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
