Description

UV Air Filter

This novel invention relates to an air filter, in particular to a portable personal ultraviolet air filter.

Many viruses, germs, pollutants, and allergens can spread through the air and invade the respiratory tract, affecting health conditions to a greater or lesser extent, and even life safety. To prevent this from happening, common practices include vaccination, isolating patients, wearing masks, or installing sterilization and antiviral equipment in central air conditioning systems. However, all of the above practices have different shortcomings. For example, the development of vaccines is time-consuming and expensive. When it comes to the epidemic, it is too targeted and cannot provide immediate protection; isolating patients will cause extremely high social costs; wearing a mask can only isolate the aerosols of bacteria and viruses, and cannot provide sterilization or virus-killing effects; installing sterilization and virus-killing equipment in the central air-conditioning system can prevent the spread between different rooms, but it cannot prevent the spread in the same room, and the application places are limited to places with central air-conditioning.

In order to provide more immediate protection with lower social cost, capable of sterilizing, killing viruses, reducing pollen allergies and having unlimited application places, this new device provides a portable personal ultraviolet air filter.

Therefore, a new type of ultraviolet air filter includes a housing, a protective film module, a connecting module and a filter module. The housing defines a containing space around the housing. The housing also includes an inlet and an outlet connected to the containing space. The protective film module can be detachably arranged at the inlet of the housing. The connecting module includes a first connecting component and a second connecting component that can be detachably connected to each other. The second connecting assembly is fixedly mounted on the housing, the second connecting assembly is fixedly mounted on the protective film module, the filter module is mounted in the accommodating space, the filter module includes an air inlet connected to the inlet, and an air outlet connected to the outlet, wherein the unfiltered air passes through the protective film module, enters the air inlet of the filter module, and after being filtered by the filter module, becomes filtered air and is discharged from the outlet through the air outlet.

Wherein, the first connecting component is a permanent magnet, and the second connecting component is a magnetic material.

The protective film module includes a frame and a film body, the film body is arranged in the frame, and the unfiltered air enters the filter module through the film body.

The protective film module includes a frame and a film body, and the second connecting component is fixedly mounted on the frame.

The protective film module includes a frame and a film body. The frame is made of magnetic material and serves as the second connecting component.

The filter module includes a fan and an air duct, the two ends of which are connected to the air inlet and the air outlet. The fan sends unfiltered air into the air duct, which becomes filtered air in the air duct and is discharged from the air outlet.

Among them, at least one ultraviolet module is set in the air duct.

The inner surface of the air duct is coated with an ultraviolet reflective film.

The at least one ultraviolet module includes a printed circuit board, two ultraviolet light sources, and two ultraviolet sensors: the printed circuit board has a first surface and a second surface opposite to the first surface, one of the two ultraviolet light sources is arranged on the first surface, the other of the two ultraviolet light sources is arranged on the second surface, one of the two ultraviolet sensors is arranged on the first surface, and the other of the two ultraviolet sensors is arranged on the second surface.

The air duct is spiral-shaped, and the cross-section of the air duct is circular.

The air duct has a plurality of layers, each of which is stacked on top of another. Each of the layers defines a filtering space. Each of the layers is provided with an opening. The opening of the top layer is connected to the air inlet, and the opening of the bottom layer is connected to the air outlet. The openings of the adjacent layers are connected to each other in a corresponding manner.

The plurality of layers are each provided with a protruding block in the filtering space, and an air-blocking groove is provided at the bottom of the plurality of layers at the position corresponding to the respective protruding blocks, and the protruding blocks and the air-blocking grooves of the plurality of layers adjacent to each other are sleeved together.

In this case, only one ultraviolet light source 452 may be provided on the first surface 454, and no other ultraviolet light source 452 may be provided on the second surface 455, so that the ultraviolet module 450 can be easily connected to the power source 700. Alternatively, the ultraviolet module 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 in the deep part. Alternatively, a slit may be provided in the air duct 440, and the ultraviolet light source 452 in the form of an ultraviolet lamp tube may be installed at the slit.

In some other embodiments, the air duct 440 may not be in the shape of a spiral pipe, but may be designed as a layered shape. The cross-section of the air duct 440 is rectangular. Referring to Figures 12 and 13, the air duct 440 has a plurality of layers 442, each of which is stacked on top of another.

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, and the novel effect can also be achieved. The shape of the air duct 440 can be polygonal, circular, rectangular, etc.

Among them, at least one ultraviolet module 450 is arranged on the inner surface of the plurality of layers 442. The at least one ultraviolet module 450 each 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, and the mask 600 is an arc-shaped sheet disposed at one end of the transmission tube 500, and the filtered air is blown 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 an oxygen mask, which has a good utilization rate for the filtered air and will not cause damage to the eyes and glasses like an air curtain. The mask 600 may be a helmet-type mask 600 to provide more complete protection; the mask 600 may even be part of the full-body protective clothing, and the transmission tube 500 may not be needed at this time, and the filtered air may be directly filled in the full-body protective clothing. These changes are all within the scope of the patent application of the present invention, and can be reasonably deduced by those with ordinary knowledge in the field through the implementation method of the present invention, thereby achieving the effect of the present invention.

From the above, it can be seen that the new model has several advantages:

1. By designing the size of the UV air filter to be thin, light and small, it is convenient for individuals to carry around. Compared with isolation measures, this new type provides a solution with lower social costs.

Second, since the protective film module 200 can be conveniently separated and connected to the housing 100 through the connection module 300, it is convenient to replace the protective film module 200 at any time. For example, the new film body 220 can be replaced every time after going out, or the new film body 220 can be replaced regularly when working in a high-risk place, or 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.

3. Since the UV module 450 provides sterilization, the filtered air is safer.

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

5. The size of the UV air filter is convenient to carry around. 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.
