The first connection component 310 is fixedly disposed on the housing 100 , and the second connection component 320 is fixedly disposed on the protective film module 200 .

[0069] It is worth mentioning that the connection module 300 can achieve the connection effect by using a latch and a slot to snap together, magic felt to stick together, or magnets to attract each other.

[0070] In some embodiments, the first connecting component 310 is a permanent magnet, and the second connecting component 320 is a magnetic material that can attract the permanent magnet of the first connecting component 310, such as iron, cobalt, nickel, and alloys thereof.

At least one ultraviolet module 450 includes a printed circuit board 451, two ultraviolet light sources 452, and two ultraviolet sensors 453. The ultraviolet sensor 453 can be a semiconductor type, and its function is to detect the intensity of the ultraviolet light source 452 in real time. When the ultraviolet intensity is lower than a preset threshold, the ultraviolet sensor 453 can trigger an alarm unit, allowing the user to check the ultraviolet module 450 or the power supply 700, or replace the ultraviolet light source 452, etc. The ultraviolet sensor 453 can also be one in number, for example, several ultraviolet light sources 452 share a corresponding ultraviolet sensor 453.

The power supply 700 can be a replaceable battery or a rechargeable battery. When it is a rechargeable battery, it can be connected to the mains through an electrical connection port. The type of the electrical connection port can be Type-C, Micro USB, Lighting, etc.

[0079] In other embodiments, holes may be provided on the side of the spiral air duct 440 to install the ultraviolet module 450. In this case, only one ultraviolet light source 452 may be provided on the first surface 454, and there is no need to provide another ultraviolet light source 452 on the second surface 455, so that the ultraviolet module 450 can be easily connected to the power supply 700. Alternatively, the ultraviolet modules 450 may be provided only at the two ends of the air duct 440 to avoid the difficulty of electrical connection of the ultraviolet module 450 deep inside. Alternatively, a slit may be provided in the air duct 440, and an ultraviolet light source 452 in the form of an ultraviolet lamp tube may be installed at the slit.

[0080] In other embodiments, the air duct 440 may not be in the shape of a spiral pipe, but may be designed as a layered body, and the cross section of the air duct 440 may be rectangular. Fig.12 and Fig.13 The air duct 440 has a plurality of layers 442, each of which is stacked on top of another. Each of the plurality of layers 442 defines a filter space 443 around it. Each of the plurality of layers 442 has an opening 444. The opening 444 of the top layer is connected to the air inlet 410, and the opening 444 of the bottom layer is connected to the air outlet 420. The openings 444 of the plurality of layers 442 adjacent to each other are connected to each other. It is worth mentioning that each layer 442 can also be spaced apart from the fan 430, or the air duct 440 can also include only one layer 442, which can also achieve the effect of the present application. The shape of the air duct 440 can be polygonal, circular, rectangular, etc.

[0081] At least one ultraviolet module 450 is disposed on the inner surface of the plurality of layers 442. Each of the at least one ultraviolet module 450 includes a printed circuit board 451, an ultraviolet light source 452, and an ultraviolet sensor 453.

The transmission tube 500 transmits the filtered air from the housing 100 to the mask 600 . The transmission tube 500 and the mask 600 can be in various forms. The mask 600 is an arc-shaped sheet arranged at one end of the transmission tube 500, which blows the filtered air to the user's mouth and nose to form an air curtain; the mask 600 can also be an ear-hanging mask, and a hole is opened on the mask 600 to connect with the transmission tube 500; the mask 600 can also be in the form of an oxygen mask, which has a good utilization rate for the filtered air and will not cause discomfort to the eyes and glasses like an air curtain; the mask 600 can also be a helmet-type mask 600 to provide more complete protection; the mask 600 can even be part of a full-body protective suit, and at this time, the transmission tube 500 is not needed, and the filtered air is directly filled in the full-body protective suit. These changes are all within the scope of protection of the present application, which can be reasonably deduced by those skilled in the art through the implementation method of the present application, and thus achieve the effect of the present application, so these changes are all within the scope of protection of the present application.

[0084] From the foregoing, it can be seen that the present application has several advantages:

[0085] 1. By designing the volume of the ultraviolet air filter to be light, thin and short, it is easy for individuals to carry around. Compared with isolation measures, this application provides a solution with lower social cost.

[0086] Second, since the protective film module 200 can be conveniently separated and connected to the shell 100 through the connecting module 300, it is convenient to replace the protective film module 200 at any time. For example, a new film body 220 can be replaced after each outing, or a new film body 220 can be replaced regularly when working in a high-risk place. Alternatively, the film body 220 can be designed as a protective material that can be washed and used multiple times, thereby extending the service life of the protective film module 200.

[0087] 3. Since the UV module 450 provides sterilization effect, the filtered air is safer.

[0088] Fourth, the ultraviolet air filter can use its transmission tube 500 and mask 600 to transmit the filtered air to the user, thereby instantly protecting the user from the invasion of germs or pollen.

[0089] 5. The size of the UV air filter is convenient to carry. Compared with installing sterilization equipment in the central air-conditioning system in the building, the application of the UV air filter is more flexible and free, and can protect different users in the same room.
