Description
Technical Field
The invention relates to the technical field of air purification, in particular to personal air purification equipment.
Background
Air pollutants such as haze in a living environment and dust in a factory working environment seriously affect life and work of people, and personal portable or wearable air purifiers developed in the year are increasing day by day. For example, patents US2003154983a1, US2007240716a1, CN2015106785768 disclose wearable personal air purification systems, which are mainly composed of a purifier, a purifier fixing device and a gas transmission conduit, wherein the filtering material, the gas transmission conduit and the gas transmission mode used for filtering all have certain defects.
For the filtering material, in order to save the space of the personal air purification equipment, the existing personal air purification equipment adopts single-layer filter paper or filter cloth, or adopts composite filtering material or active carbon filter screen which is applied to a common PM 2.5-proof mask and compounded with active carbon, the simple single-layer filtering material has poor filtering and purifying effects, sometimes, the simple single-layer filtering material is only psychologically effective, and the actual air purification effect is far from the standard; secondly, the service life of the single-layer filter paper or the composite activated carbon filter paper is very short, and the filter paper needs to be replaced in a short time; thirdly, after the active carbon is compounded into the single thin filter paper, the actual adsorption effect is greatly reduced; meanwhile, in the prior art, the arrangement of the filtering material is always the whole surface of the purifying equipment, and in the actual air inlet process, the filtering function of only part of the filtering material close to the fan can be applied; finally, because the single-layer filter paper is thin, the air purifier is arranged in an air inlet area of the personal air purifier, air leakage often occurs, and a lot of air entering the air purifier is directly discharged without being filtered by the filter paper, so that the air purification effect is greatly weakened.
For the air delivery conduit, the air delivery conduit applied in the personal air purification system is often directly made of transparent plastic or rubber conduit similar to hospital, and the conduit applied in the personal air purification equipment has a plurality of defects. Firstly, the diameter of an air duct in the actual duct of the duct is small, the air ventilation efficiency is not high, the power for driving the air in the duct to flow in the personal air purification system is effective, and the air ventilation effect is obviously low due to a narrow air ventilation cavity; secondly, the medical ventilation catheter is usually directly screwed or sleeved on a purifier or related air outlet equipment (such as a mask), so that the equipment is very complicated to assemble and disassemble, and the assembled effect is similar to that of a gas mask and is very unattractive; thirdly, the length of the traditional medical plastic or rubber catheter cannot be stretched and adjusted, and only a quantitative cutting mode is adopted, so that the length of the ventilation pipeline is inconvenient to adjust; more importantly, when the personal air purification device is worn on a human body, a certain bending angle is formed between the air duct and the purifier and between the air duct and the air delivery device (such as a mask), and when the personal air purification device is used, the bending angle of the guide pipe is too small, so that the air volume can be greatly reduced and even disappear, and great inconvenience is caused.
To the mode of supplying air, traditional personal air purification equipment is used for the gas transmission including gauze mask or face guard, the mode of disinfection mask pattern is all adopted to the connected mode, set up the air vent at gauze mask or face guard front portion or centre (notice, gauze mask or face guard can not pass through the air except that the air vent other parts), air vent connection air conduit, this kind of connected mode is not only pleasing to the eye, can obstruct the sight in the front simultaneously when using, more importantly, this kind of permeability that contains the face guard or gauze mask itself is poor or airtight complete, once air supply system goes wrong, for example, power supply electric quantity is short of, fan trouble or air supply conduit buckle completely and block etc. can cause the exhaust of certain degree, lead to the sense of suffocation and increase, can even lead to oxygen deficiency and the risk of suffocation under the serious condition.
