Description

Air filter device and cover body with air filter device

This creation is about an air filter device and a cover with an air filter device, in particular an air filter device and a cover with an air filter device through aerogel, photocatalyst and nanofiber.

The novel coronavirus (COVID-19), which spread rapidly to many countries around the world in early 2020, is highly contagious, and asymptomatic infections may also become the source of infection. There has been a major and sustained human-to-human transmission in many countries, which was caused at one time. The global pandemic, and the sudden epidemic made people unable to cope for a while. At that time, there was no effective vaccine against the new coronavirus (COVID-19) and no specific medicine for this viral pneumonia. People can only prevent infection by washing hands frequently, keeping interpersonal distance, and touching their faces less. At the same time, people who are suspected of being infected can reduce the chance of infecting others by wearing a mask. In response to the panic buying of masks in countries around the world, disposable masks not only cause environmental pollution, but if they are infected with viruses, they will expand the infection and cause out of control.

The Republic of China Patent Announcement No. M592498 "Portable Multifunctional Air Purifier", the creation is to provide a portable multifunctional air purifier, which can be used indoors, in a car, or walked on its back, transmitted through a transmission air duct To the mask for use; the clean technology uses photocatalyst materials such as tungsten trioxide WO3 and plasma technology to purify the air. Among them, the WO3 photocatalyst material is stable in nature and has a wide absorption band. It is not only limited to ultraviolet light, but will work under visible light. Using low-temperature plasma sterilization technology, this purifier is multi-functional and can sterilize and purify organic gases and dust; the purifier can be illuminated according to different air quality indicators, and the vent pipe at the outlet can be connected to the mask, which is convenient for some air quality indicators. In poor countries or regions, carry it with you. When using the mask mode, temporarily turn off the photocatalyst cleaning mode.

However, the aforementioned patents only filter the inhaled air through the UV lamp and the filter, which cannot effectively isolate fine suspended particles (PM2.5) and viruses, and in the mask mode, the inhaled air cannot be filtered through the photocatalyst.

In this regard, the author proposes an air filter device, which includes: a top cover with an air outlet and a top cover connecting part; a bottom cover with an air inlet and a bottom cover connecting part; a plurality of stepped components , The inner peripheral surface of the stepped components extends toward an axial direction to form a partition plate, the partition plate is provided with a through hole, and the stepped components are respectively provided with a first joint portion and a second joint portion. A plurality of stepped components are connected to the top cover and the bottom cover in sequence along the axial direction, the first joining part is connected to the adjacent top cover joining part or the adjacent second joining part, and The second connecting portion is connected to the adjacent bottom cover connecting portion or to the adjacent first connecting portion, between the partition and the top cover, between the partition and the bottom cover, and any of An accommodating space is formed between the two partitions, and the accommodating space is directly or indirectly connected with the air outlet and the air inlet, so that the accommodating space, the air outlet and the air inlet form a gas Channel; an aerogel material arranged in the accommodating space; a photocatalyst material arranged in the accommodating space; a nanofiber material arranged in the accommodating space.

Further, a drainage module is clamped in the accommodating space to assist in inhaling outside air from the air inlet and exhausting from the air outlet through the air passage.

Further, the drainage module includes a fan blade, a motor and a battery.

Further, the battery has a charging terminal, and the charging terminal is arranged on the outer peripheral surface of the stepped component.

A cover body with an air filter device includes the aforementioned air filter device, and further includes: a cover body including a connecting port connected to the air outlet.

Further, the cover includes a mask, a face mask or a head cover.

Furthermore, the top cover, the bottom cover or the stepped component is provided with a strap.
