Description

Air sterilization module and air sterilization equipment including the same

The present invention relates to an air sterilization module and an air sterilization device comprising the same.

There are many kinds of bacteria, fungi and viruses in the air, which are easy to multiply in humid and poorly ventilated environment. In daily life, people often keep doors and windows tightly closed to prevent the dust and dust from polluting the indoor environment, and use the air conditioner for a long time to maintain a comfortable body temperature. However, these habits will cause poor air circulation in the indoor environment, or It is the rise of relative humidity, which forms a breeding ground for germs. Therefore, in recent years, the market for air cleaning or air reduction products has become very hot.

In terms of air sterilization effect, especially UV light has an excellent sterilization effect, but due to the sterilization characteristics of UV light, it cannot rapidly reduce bacteria in a short time. The contact time of UV light, or the increase of the intensity of UV light, can achieve the required sterilization effect. Therefore, in order to achieve the sterilization effect of the conventional air sterilization equipment, the size of the equipment cannot be greatly reduced, resulting in the size of the equipment. huge. In addition, since exposure to long-term and high-intensity UV light is harmful to the human body, especially skin or eye lesions, it is generally necessary to clear the environment when using UV light for sterilization. limit.

As mentioned above, since the conventional air sterilization equipment cannot effectively utilize UV light, it has disadvantages such as bulky size, high energy consumption, increased cost, low sterilization efficiency or poor sterilization effect. Therefore, there is an urgent need to propose a new air sterilization module or air sterilization device to eliminate or alleviate the above problems.

In view of this, the present invention proposes an air sterilization module and an air sterilization device including the same, which have the advantages of reduced volume, energy saving, cost reduction, improved sterilization efficiency, or enhanced sterilization effect.
