The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0028] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0029] like Figure 1-Figure 3 As shown, an embodiment of the utility model provides a nano-silver antibacterial and antiviral mask, comprising a mask body 100, which is used to be worn on the mouth and nose of a user, and an air intake structure 200 and an air outlet structure 300 are provided on the mask body 100.

[0030] In this embodiment, two groups of air inlet structures 200 are provided, which are respectively located on the left and right sides of the mask body 100 , and one group of air outlet structures 300 is provided, which is located in the middle of the mask body 100 .

[0031] Reference Figure 3 The air intake structure 200 includes an air intake hole 210 , a filter housing 220 , a nano silver filter assembly 230 and a pressure ring 240 .

[0032] The air inlet hole 210 is disposed on the mask body 100 , and a retaining ring 211 is disposed on the hole wall at the inner end of the air inlet hole 210 .

[0033] The filter housing 220 is detachably connected to the outer end of the air inlet hole 210, and an air inlet mesh plate 221 is provided on the outer side of the filter housing 220, and a filter installation groove 222 is formed on the inner side of the filter housing 220. Figure 1 and Figure 3 A plurality of slots 212 are provided on the hole wall at the outer end of the air inlet 210 along the axis, a locking slot 213 is provided on the same side of the inner end of each slot 212 along the circumferential direction, and a plurality of locking blocks 223 are provided on the outer wall at the inner end of the filter housing 220, and each locking block 223 can be inserted into each slot 212 and screwed into each locking slot 213 one by one. When installing the filter housing 220, align the locking block 223 on the filter housing 220 with the slot 212 inserted into the inner wall of the air inlet 210, insert the locking block 223 to the bottom, and then rotate the filter housing 220 by an angle so that the locking block 223 is inserted into the slot 212.

[0034] The nanosilver filter assembly 230 is placed in the filter installation slot 222. The nanosilver filter assembly 230 of this embodiment includes a nanosilver filter and one or more of a primary air filter, a medium efficiency air filter, a high efficiency air filter and an activated carbon filter. The nanosilver filter and different filters can be combined into different nanosilver filter assemblies 230.

[0035] The pressing ring 240 is adapted to fit into the filter installation groove 222 and is pressed against the periphery of the nano-silver filter assembly 230 . A compression spring 250 is provided between the pressing ring 240 and the retaining ring 211 .

[0036] The filter housing 220 of the present application can be removed and replaced. When installing the nanosilver filter assembly 230, the nanosilver filter assembly 230 is loaded into the filter housing 220, and then the filter housing 220 is installed in the air inlet 210. The pressure ring 240 in the air inlet 210 is inserted into the filter housing 220 and pressed against the periphery of the nanosilver filter assembly 230 under the action of the compression spring 250, thereby achieving the fixation of the edge of the nanosilver filter assembly 230. By arranging the compression spring 250 on the inner side of the pressure ring 240, even if the thickness of the nanosilver filter assembly 230 changes within a certain range, it can be ensured that the pressure ring 240 presses the nanosilver filter assembly 230. Therefore, the present application can be applicable to the installation of filter assemblies of different thicknesses, and is convenient for using filter assemblies of different thicknesses.

The outer end of the air outlet hole 310 is provided with an air outlet mesh plate 311, and the exhaust fan 320 is installed in the exhaust fan 320. Although the nano-silver filter assembly 230 with a multi-layer filter combination can improve the filtering effect, it will increase the resistance of the air flow. In this embodiment, by setting the air intake fan 260 and the exhaust fan 320, when wearing the mask, the air intake fan 260 and the exhaust fan 320 can be actively ventilated, thereby reducing the resistance to breathing.

[0038] In order to guide and limit the pressure ring 240, the outer end of the inner ring body 214 is provided with an outer convex edge 215 protruding from the outer peripheral surface, the inner peripheral edge of the pressure ring 240 is provided with an outer ring body 241 extending inward, and the inner end of the outer ring body 241 is provided with an inner convex edge 242 protruding from the inner peripheral surface. The inner convex edge 242 is adapted to the outside of the inner ring body 214 and is limited between the outer convex edge 215 and the retaining ring 211.

[0039] In this embodiment, a protective mesh plate 243 is provided inside the pressure ring 240 to prevent external debris from falling into the air intake fan 260 when replacing the filter assembly.

[0040] In order to improve the comfort of wearing the mask and improve the sealing between the edge of the mask body 100 and the face, a face contact soft rubber 110 is provided on the periphery of the mask body 100 .

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
