Detailed implementation manners

[0021] Hereinafter, embodiments of the technical solution of the present utility model will be described in detail with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and thus are only examples and cannot be used to limit the protection scope of the present utility model.

[0022] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which the present utility model belongs.

[0023] As Figure 1 and Figure 2 shown, an embodiment of the present utility model provides a nano silver antibacterial and antiviral filtering device, including an upper shell 100 and a lower shell 200.

[0024] The lower end of the upper shell 100 is open, the top of the upper shell 100 is provided with an air outlet 110, and a fan 300 for exhausting air to the air outlet 110 is provided inside the upper shell 100.

[0025] In order to facilitate the installation of the fan 300, the upper end of the upper shell 100 is open, a fan support platform 170 is provided along the circumference of the inner wall of the upper shell 100, the periphery of the fan 300 is supported on the fan support platform 170, and an air outlet member 180 pressing on the periphery of the fan 300 is embedded and installed in the opening at the upper end of the upper shell 100, and the air outlet 110 is provided on the top plate of the air outlet member 180.

[0026] The top plate of the air outlet member 180 in this embodiment is preferably in a horn shape with the middle part sunken downward, which is not only beautiful in shape but also beneficial to the diffusion of the air flow at the air outlet 110.

[0027] The fan 300 in this embodiment includes a fan housing 310 having two air ducts 311 and cross-flow fans 320 respectively installed in the two air ducts 311. Of course, in other embodiments, the fan 300 can also adopt an axial flow fan 300.

[0028] The upper end of the lower shell 200 is open. An air inlet 210 is provided on the side wall of the lower part of the lower shell 200. A filter support platform 220 is provided along the circumference on the inner wall of the middle part of the lower shell 200. A nano-silver filter 400 supported on the filter support platform 220 is provided inside the upper part of the lower shell 200. The lower end of the upper shell 100 is inserted into the opening at the upper end of the lower shell 200 and presses the edge of the nano-silver filter 400 against the filter support platform 220. At the same time, the upper shell 100 and the lower shell 200 are connected by snap-fasteners.

[0029] Specifically, one snap hole 230 is provided near the upper end on each side of the lower shell 200. One hook 120 is provided near the lower side on the outer side of each side of the upper shell 100. Each hook 120 can be correspondingly snapped into each snap hole 230. A hook retraction groove 130 is provided on the outer side of the upper shell 100 at the position corresponding to the hook 120. When the lower end of the upper shell 100 is inserted into the lower shell 200, the hooks 120 on both sides of the upper shell 100 are automatically aligned and snapped into the snap holes 230 on both sides of the lower shell 200, thereby realizing the locking between the upper shell 100 and the lower shell 200. When it is necessary to disassemble the upper shell 100 and the lower shell 200, the hooks 120 on both sides of the upper shell 100 are squeezed inward, so that the hooks 120 withdraw from the snap holes 230, and then the upper shell 100 can be pulled out from the lower shell 200.

[0030] In order to ensure that when the upper shell 100 is inserted into the lower shell 200, the lower end of the upper shell 100 can press the edge of the nano-silver filter 400, an elastic pressing member is provided at the lower end of the upper shell 100. The lower end of the upper shell 100 is pressed against the nano-silver filter 400 through the elastic pressing member. Specifically, an installation groove 140 is provided near the lower end on the inner side of the upper shell 100. The elastic pressing member includes a pressure ring 150 and a plurality of springs 160. A guiding ring 151 adapted to be inside the installation groove 140 is provided at the upper end of the pressure ring 150. Each spring 160 is respectively supported between the top of the installation groove 140 and the guiding ring 151.

[0031] In this embodiment, the nano-silver filter 400 specifically includes a coarse filter screen 410, a HEPA filter screen 420, an activated carbon filter screen 430, and a nano-silver filter screen 440 which are arranged in sequence from bottom to top. The coarse filter screen 410 is used for primary filtration and can filter dust particles larger than 5 microns. The HEPA filter screen 420 can filter very small particles, and the removal efficiency of particles with a diameter of more than 0.3 microns can reach more than 99.97%. The activated carbon filter screen 430 can effectively adsorb various odors and harmful gases in the air, such as formaldehyde and benzene, as well as some volatile organic compounds (VOCs). The nano-silver filter screen 440 has good antibacterial efficacy and can inhibit the growth and reproduction of microorganisms such as bacteria and fungi, reducing the microbial contamination in the air.

[0032] When the fan 300 in this embodiment is working, it will drive the air flow to flow upward. The external air is inhaled into the lower shell 200 through the air inlet 210, and after passing through the nano-silver filter 400 to filter out pollutants such as particulate matter, harmful gases, odors, bacteria and viruses, it enters the upper shell 100, and then is discharged from the air outlet 110, thereby realizing air filtration.

[0033] When the nano-silver filter 400 needs to be maintained or replaced, unfasten the buckle between the upper shell 100 and the lower shell 200, and separate the upper shell 100 and the lower shell 200. Then the nano-silver filter 400 in the lower shell 200 can be disassembled. After the nano-silver filter 400 is disassembled, a new filter can be replaced, or foreign matters can be cleaned with a brush or water. Then the nano-silver filter 400 is reinstalled into the lower shell 200, and the lower end of the upper shell 100 is inserted into the lower shell 200, so that the lower end of the upper shell 100 presses the edge of the nano-silver filter 400 against the filter support table 220. At the same time, the upper shell 100 and the lower shell 200 are locked by the buckle, and the installation of the nano-silver filter 400 can be realized. Therefore, the structure of this filtering device is simple, and the installation and disassembly of the nano-silver filter 400 are convenient.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
