Portable air filtering device

Abstract

The invention provides a portable air filtering device which comprises a backpack and a treater, wherein the treater comprises a box body and a cover plate; the cover plates covers the box body so as to combine the box body and the cover plate as a square of which one side surface is opened; the internal space of the box body is sequentially divided into a treating area and an air storage area from the opening in the side surface from outside to inside; a detachable filtering plate, a positive electrode plate and a negative electrode plate are sequentially inserted into the treating area from outside to inside; air outlet holes are formed in the side wall of the air storage area in the box body so as to communicate the air storage area with a fan which is tightly adhered to the side surface of the box body; the fan is opened upwards and is connected with an air cylinder; a soft air conveying tube is connected with the top opening of the air cylinder through a first connector; a battery box is fixed at the bottom of the box body; the battery box is connected with the fan and an electrostatic generator to supply power through circuits; the electrostatic generator is connected with the positive electrode plate and the negative electrode plate and is used for supplying high-voltage static electricity. The portable air filtering device is small in size, easy to carry over and light in weight, and can well replace a mouth-muffle for effectively reducing the influence of air pollution to bodies when people live at home or go out.

Description

technical field [0001] The invention relates to a portable air filter device, which belongs to the field of air filter devices. Background technique [0002] Due to various reasons, the air problem has become one of the biggest environmental problems at present. For ordinary people, it is too far away to control the atmospheric environment, and it is not reliable to carry medium and large air treatment devices with them. As a way to reduce the negative impact of smog when going out , there is almost no choice but to wear a mask or a gas mask. However, as a daily wear, wearing a gas mask is an unimaginable choice, so it is only possible to wear a mask, but limited by the structure and size of the mask itself, its effect on the air Purification can only stop at simple filtration, mainly using activated carbon filter layer to adsorb air pollutants. Although this can play a certain role, as far as the current air pollution situation is concerned, such a role is really limited O...

[0002] Due to various reasons, the air problem has become one of the biggest environmental problems at present. For ordinary people, it is too far away to control the atmospheric environment, and it is not reliable to carry medium and large air treatment devices with them. As a way to reduce the negative impact of smog when going out , there is almost no choice but to wear a mask or a gas mask. However, as a daily wear, wearing a gas mask is an unimaginable choice, so it is only possible to wear a mask, but limited by the structure and size of the mask itself, its effect on the air Purification can only stop at simple filtration, mainly using activated carbon filter layer to adsorb air pollutants. Although this can play a certain role, as far as the current air pollution situation is concerned, such a role is really limited On the other hand, since masks only have the function of filtering, they have little effect on airborne germ pollution. Due to this limitation, some people with low resistance are still infected by germs in the air even if they wear multi-layer masks. while sick
