Detailed Description
Example 1
As shown in fig. 1, 2 and 3, a portable spray protection device. The box-shaped body comprises a box-shaped body 1 with an upper end panel 11, wherein the upper end panel 11 is at least provided with a first strip-shaped hole 21 and a second strip-shaped hole 22; an air inlet guide port 31 and an air outlet guide port 32 are respectively arranged below the upper end panel 11 and in the box-shaped body 1, the air inlet guide port 31 is positioned below the first strip-shaped hole 21, and the air outlet guide port 32 is positioned below the second strip-shaped hole 22; the air inlet guide opening 31 and the air outlet guide opening 32 in the box-shaped body 1 are separated to form a spray absorption area 41 and a fresh air output area 42, and the spray absorption area 41 and the fresh air output area 42 in the box-shaped body 1 are provided with a fan 5.
In this embodiment, the fan 5 is a crossflow fan, such as: taiwan Sanju AC crossflow fan (model SJ5115HA 2), FS-CA30150B crossflow fan of Shenzhen Shencheng motor Limited and the like. The crossflow blower has a wide width, a simple structure, a small volume, and is generally suitable for an air curtain device, and thus can be matched with the first elongated hole 21 and the second elongated hole 22.
In this embodiment, the first elongated hole 21, the air inlet guide port 31, or the droplet absorbing region 41 has the first filter material 61 therein, and virus particles entering the droplet absorbing region 41 can be adsorbed. The second strip-shaped hole 22 or the air outlet guide opening 32 or the fresh air output area 42 is provided with a second filter material 62, so that air which is blown out from the second strip-shaped hole 22 and forms an air curtain in the fresh air output area 42 can be filtered. The first filter 61 and the second filter 62 may be made of filter core materials such as N series (N95, N99) masks or other filters according to the protection requirement. Further, the efficiency of the droplet adsorption needs to be emphasized more in selecting the first filter 61.
