Description

Air filter sterilization device

The invention relates to an air filter and sterilizer, in particular to an air filter and sterilizer which can be sterilized by ultraviolet rays.

In the current medical behavior, medical staff and patients often have close contact. In order to prevent medical staff from being infected by viruses or bacteria scattered in the air, medical staff sometimes wear full-body protective clothing or protective masks. However, in the prior art, the gas supplied to the medical staff wearing full-body protective clothing or protective masks usually only has to be filtered by a filter screen or filter tank. However, the degree of filtration of the filter screen or filter tank is limited, and it is impossible to completely remove the virus or bacteria attached to the air particles. So healthcare workers could still be infected.

Therefore, be necessary to invent a kind of new air filter sterilization device, to solve the deficiency of prior art.

The main purpose of the present invention is to provide an air filter and sterilizer, which can utilize ultraviolet rays to sterilize.

In order to achieve the above-mentioned purpose, the air filter sterilization device of the present invention is used for supplying gas. The air filtration and sterilization device includes a body, an air inlet, a channel, an ultraviolet lamp and an output port. The air inlet is connected to the body for inputting gas. The channel is located in the body and connected to the air inlet for circulating gas. The ultraviolet lamp is located in the body and adjacent to the channel, and is used to emit ultraviolet rays to sterilize the gas flowing through the channel. The output port is located on the body and connected to the channel for outputting gas.

In order to allow your review committee members to better understand the technical content of the present invention, the preferred specific embodiments are described as follows.

Please refer to FIG. 1 below, which is a schematic diagram of the structure of the air filtration and sterilization device of the present invention.

In the embodiment of the present invention, the air filter and sterilizer 1 is used to supply a gas, and its volume is small so that it is convenient to carry. The air filtration and sterilization device 1 includes a body 10 , an air inlet 20 , a channel 31 , an ultraviolet lamp 32 and an output port 40 . The body 10 can be a plastic shell, but the invention is not limited thereto. The air inlet 20 is connected to the body 10 for inputting gas. The air inlet 20 can be further provided with a filter screen 21 and a fan 22 . The specification of the filter screen 21 can be HEPA or activated carbon, etc., and the present invention is not limited thereto. The fan 22 is arranged adjacent to the filter screen 21 to rotate. Therefore, the flow of gas can be increased by the operation of the fan 22 . On the other hand, the fan 22 can also be replaced by a pump, or the fan 22 can be combined with a pump to achieve the purpose of sucking gas, but the present invention is not limited to this structure.

The channel 31 is located in the body 10 and connected to the air inlet 20 for passing through the gas. The present invention does not limit the shape of the channel 31 . In Fig. 1, the channel 31 has a plurality of bends 33, thereby increasing the gas transmission distance. However, the channel 31 can also be linear or helical. The ultraviolet lamp 32 is a light-emitting diode, located in the body 10 and adjacent to the channel 31 , for emitting an ultraviolet ray to sterilize the gas flowing through the channel 31 . The number of ultraviolet lamps 32 can be set according to the shape or length of the channel 31 . When the channel 31 has a plurality of bends 33, a plurality of ultraviolet lamps 32 can be arranged on the plurality of bends 33 or straight lines, so as to increase the probability of being sterilized by ultraviolet radiation when the gas circulates. Furthermore, the plurality of bends 33 of the channel 31 can also be coated with a reflective paint, so as to reflect ultraviolet rays, so that the ultraviolet rays can completely irradiate every part of the channel 31 .

Finally, the output port 40 is located on the body 10 and connected to the channel 31 for outputting the sterilized gas.

Finally, please refer to FIG. 2 which is a schematic diagram of the use of the air filter sterilization device of the present invention.

Finally, the output port 40 is directly connected or connected to a protective clothing 2 by the connecting pipe 2a. The output port 40 of the air filter and sterilization device 1 can also be used to be connected to a mask or a mouth mask, and the present invention is not limited thereto. In this way, when wearing the protective clothing 2, face mask or mask, the air filtration and sterilization device 1 can prevent the user from inhaling the gas with viruses or bacteria, so as to obtain the most complete protection.

It should be noted that this embodiment is only an example of a preferred embodiment of the present invention, and all possible combinations of changes are not described in detail to avoid redundant description. However, those skilled in the art should understand that not all the above-mentioned modules or components are necessary. And in order to implement the present invention, other more detailed conventional modules or components may also be included. Each module or component may be omitted or modified as required, and there may not be other modules or components between any two modules. As long as it does not deviate from the basic structure of the present invention, it shall be within the scope of rights claimed by this patent, and the scope of patent application shall prevail.
