Description

Personal air purification equipment

Technical field

The invention relates to the technical field of air purification, and in particular to a personal air purification device. Background technique

Air pollutants such as smog in the living environment and dust in the working environment of the factory seriously affect people's lives and work, and the number of personal portable or wearable air purifiers developed this year is increasing. A wearable personal air purification system is disclosed, for example, in the patents ij US2003154983 A1, US2007240716 A1, and CN2015106785768. The purification device is mainly composed of a purifier, a purifier fixing device, and a gas conduit, wherein the filter material used for filtering, There are some defects in the gas pipeline and the air supply method.

For the filter material, in order to save space for personal air purification equipment, the existing personal air purification equipment uses a single layer of filter paper or filter cloth, or a composite filter material or activated carbon filter that is combined with activated carbon in a common PM2.5 mask. Net, this simple single-layer filter material filtration and purification effect is not good, sometimes even just psychological effects, the actual effect of purifying the air is far from the standard; Secondly, the use of single-layer filter paper or composite activated carbon filter paper often has a very long life Short, the filter paper needs to be replaced in a short time; again, after the activated carbon composite enters the thin filter paper, the actual adsorption effect will be greatly reduced; at the same time, the placement of the filter material in the prior art is often the entire surface of the purification device, and in actual practice In the gas process, only the filtering function of part of the filter material close to the fan can be applied. Finally, since the single-layer filter paper is very thin, it is placed in the air inlet area of the personal air purification device, and there are often air leakage situations, many entering the device. The air is not filtered directly through the filter paper. Discharge, greatly reducing the air purification effect.

For gas pipelines, gas pipelines used in personal air purification systems often use hospital-like transparent plastic or rubber conduits, which are used in personal air purification equipment. First of all, the diameter of the ventilation duct in the actual catheter of this type of catheter is small, the ventilation efficiency is not high, and the dynamics of the air flow in the drive tube in the personal air purification system is effective, and the narrow ventilation cavity obviously causes the ventilation effect to be low; Ventilation ducts are often threaded or sleeved in purifiers or vented Related equipment (such as masks), which makes the assembly and disassembly of the equipment very cumbersome, and the assembled effect is similar to the gas mask, very unattractive; again, the traditional medical plastic or rubber catheter length is not scalable and adjustable, only It is very inconvenient to adjust the length of the ventilation duct by means of quantitative cutting; more importantly, when the personal air purification equipment is worn on the human body, the ventilation duct and the purifier, the ventilation duct and the gas transmission device (such as the mask) have certain The bending angle, when used, the bending angle of the catheter is too small, which can greatly reduce or even eliminate the ventilation, causing great inconvenience.

For the air supply method, the traditional personal air purification equipment includes a mask or a mask for gas transmission, and the connection method is a disinfectant mask style. A vent hole is formed in the front or the middle of the mask or mask (note that the mask or mask except the vent hole) The other part does not pass through the air. The vent is connected to the air duct. This type of connection is not only unsightly, but also obstructs the front line of sight during use. More importantly, the mask or the mask itself has poor air permeability or airtightness. Completely, once there is a problem with the air supply system, such as lack of power supply, fan failure, or complete bending of the air supply duct, it will cause a certain degree of lack of air supply, resulting in increased suffocation and, in severe cases, even a risk of hypoxia and suffocation.
