As used herein, the term "connected" refers to an operative coupling or link. The linked objects may be directly coupled to each other or may be indirectly coupled to each other via another set of objects.

As used herein, relative terms, such as "inside," "interior," "exterior," "top," "bottom," "front," "back," "upper," "lower," "vertical," "lateral," "above … …," and "below … …," refer to the orientation of a group of objects relative to one another as a matter of manufacture or use, for example, according to the drawings, but do not require the particular orientation of the objects during manufacture or use.

According to an embodiment of the present application, as shown in fig. 1, there is provided a sterilizing filter net including: a base fabric 12; a silver printed circuit 14 and an ultraviolet light source 16 disposed on the surface of the base fabric 12; the silver printed circuit 14 is connected to an electrode of the ultraviolet light source 16.

In the power-on state, the ultraviolet light source 16 generates ultraviolet light, and the ultraviolet light has a good sterilization effect on common germs, so that the residues of the germs on the filter screen can be inhibited. In addition, the silver printed circuit 14 serves as a lead connecting the ultraviolet light source 16 and the external power supply module, and has not only good conductivity but also sterilization function. In the present application, the silver print 14 is printed directly onto the base fabric 12, and since the silver print 14 is not a bulk metal, it has good foldability and can be used with multiple folds of the base fabric 12 without breaking. Compared with the common electric wire, the silver printed circuit 14 can be completely attached to the base fabric 12, and the occupied volume is smaller, so that the structure of the sterilization filter screen is simpler.

In the present application, the inventor designs the silver printed circuit 14 and the ultraviolet light source 16 on the surface of the base fabric 12 integrally, and does not use the common electric wire as the conducting wire of the ultraviolet light source 16, so that the obtained sterilizing filter screen basically keeps the original shape of the base fabric 12, and the structure is very convenient. The sterilization filter screen has the sterilization effects of ultraviolet rays and silver materials, has dual sterilization effects, and can kill bacteria with types and sterilization intensity far larger than the sterilization effect of a single mode.

The silver printed circuit 14 includes a polymeric medium and a silver component dispersed in the polymeric medium. The preparation process can be obtained by printing the ink containing the silver component and the polymer medium precursor on the base fabric 12, drying and curing, and a sintering process can be included in the drying and curing process. The printing means includes, but is not limited to, screen printing, ink jet printing, and the like.

The silver component in the silver printed circuit 14 includes silver nanowires, silver nanoparticles, or silver nanoplates. In some embodiments, to enhance the conductive properties of the printed circuit 14, the silver nanomaterials can be interconnected. For example, when the silver component is silver nanowires, a plurality of silver nanowires are connected to each other in a staggered manner to form a mesh structure.

The silver printed circuit 14 may be a conductive line. The conductive lines may be in a transverse as well as a longitudinal array across each other. The line width of the conductive lines is preferably less than 1 mm and the thickness of the conductive lines is preferably less than 1 mm. The electrodes of the uv light source 16 include a cathode and an anode, which are connected to different conductive lines, respectively.

In one embodiment, the ultraviolet light source 16 is a micro light emitting diode. Micro-leds refer to leds having dimensions on the order of microns, preferably between 100 and 500 microns. A plurality of micro leds may be uniformly distributed on the surface of the base fabric 12.

An adhesive member, which may be an adhesive, is also disposed between the ultraviolet light source 16 and the base fabric 12. The base fabric 12 may be a non-woven fabric, a metal mesh fabric, a metal fiber fabric or a carbon fiber fabric non-woven fabric. Preferably, the base fabric 12 is a non-woven fabric, which is made of oriented or random fibers and has the advantages of moisture resistance, air permeability and the like. When the non-woven fabric is adopted as the base fabric 12, gas can easily permeate the base fabric 12, thereby being beneficial to the application of the sterilization filter screen in the field of gas filtration. The material forming the base fabric 12 includes, but is not limited to, polyester, polypropylene, nylon, spandex, acrylic, and the like.

The application also provides a sanitary protection article, which comprises the sterilizing filter screen and a power module connected with the sterilizing filter screen, wherein the power module is used for controlling the luminous intensity of the ultraviolet light source. The power module comprises a power switch, a battery, other electronic components and the like.

The sanitary protective articles can be masks, protective clothing, protective caps, isolation clothes, experimental clothes or shoe covers.

Although the present disclosure has been described and illustrated in greater detail by the inventors, it should be understood that modifications and/or alterations to the above-described embodiments, or equivalent substitutions, will be apparent to those skilled in the art without departing from the spirit of the disclosure, and that no limitations to the present disclosure are intended or should be inferred therefrom.
