Description

air purification device

The present invention relates to air filters; in particular, it refers to an air purification device.

Today, humans are exposed to the dangers of air pollution. Breathing was originally necessary to maintain life, but now breathing may cause harm to the body. The concentration of PM2.5 in the air is increasing year by year. Long-term inhalation of fine suspended particles may cause allergies and asthma attacks, and also increase the incidence of lung adenocarcinoma or other cancers. In addition, during the period when the epidemic is raging, people are more worried about contracting the disease from inhaling the virus.

In the past, there have been various air purification devices, such as car air purifiers, household air purifiers, etc. However, these air purifiers are usually placed on a flat surface to purify the air within a specific range. They are not convenient to carry. Moreover, when there is wind in the air, it is impossible to ensure that the inhaled air has been purified. Even if there are portable disinfection and sterilization devices on the market, they usually use the principle of emitting negative ions to absorb air pollution to achieve the effect of purifying the air. Therefore, it is impossible to ensure that all inhaled air has been purified. Therefore, the known disinfection and sterilization devices still have room for improvement.

In view of this, the purpose of the present invention is to provide an air purification device that not only ensures that the inhaled air is disinfected and purified, but is also convenient for the user to carry and can purify the exhaled air.

Both ends of the heat dissipation tube 62 are connected with the solution bottle 22 of the filter unit 20, so that the solution S in the solution bottle 22 can flow out from one end of the heat dissipation tube 62, and then flow back to the solution bottle 22 from the other end of the heat dissipation tube 52, forming a One solution cycle. The heat dissipation pipe 62 passes through a hollow part 15 of the metal tube 14 with the UV light sources 16 , as shown in FIG. 3 , whereby the solution can take away the heat of the metal tube 14 and prevent the ultraviolet light source 16 from overheating. In addition, the aforementioned heat dissipation pipe 62 can be connected to the pump 64 to drive the solution to flow and circulate stably in the heat dissipation pipe 62 . The thermal sensor 66 can be disposed in the ultraviolet sterilization unit 10 . The thermal sensor 66 is connected to the pump 64 . The thermal sensor 66 is used to detect the temperature of the ultraviolet sterilization unit 10 . When the temperature of the ultraviolet sterilization unit 10 exceeds a predetermined value, the thermal sensor 66 transmits a signal to activate the pump 64; when the temperature of the ultraviolet sterilization unit 10 drops to a predetermined value, the thermal sensor 66 transmits a signal to turn off The Pump 64.

With the above design, the air purifying device has two flow directions and two paths. When the user inhales, the air will pass through the ultraviolet sterilization unit 10 and the filter unit 20. The ultraviolet light can kill microorganisms in the air, and the solution S can absorb impurities in the air (such as PM2.5, dust or ozone). When the user exhales, the air will also be sterilized by ultraviolet light before being discharged into the environment. Therefore, if the air exhaled by the user contains disease sources (such as bacteria or viruses), the exhaled air will first It is sterilized and disinfected by ultraviolet light before being discharged, thus preventing the spread of diseases.

In addition, when the air purifier 100 is carried and shaken by the user, the partition 26 can prevent the solution from entering the breathing tube 50 or the second extension tube 47 . Therefore, the respiratory device 100 can be carried by the user. And when the user breathes directly through the breathing tube 50, it can be ensured that all the air inhaled or exhaled has been purified.

The above are only the best possible embodiments of the present invention. Any equivalent changes made by applying the description and patent scope of the present invention should be included in the patent scope of the present invention.
