A personal air purification device

Abstract

The invention discloses a personal air purification device, which comprises a shell unit and a filter unit located in the shell unit. The shell unit is also provided with a control unit, a power supply and a suction and air supply unit connected in sequence, and the air passes through the suction and air supply unit. The air unit is purified and discharged through the filter unit; the personal air purification device of the present invention is beautiful to wear, has good air filtration effect, can prevent the air duct from not being smoothly ventilated, and can be directly adapted to ordinary masks at the same time.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a personal air purification device. Background technique [0002] Air pollutants such as smog in the living environment and dust in the factory working environment have seriously affected people's life and work, and more and more personal portable or wearable air purifiers have been developed this year. For example, patents US2003154983A1, US2007240716A1, and CN2015106785768 disclose wearable personal air purification systems. This type of purification equipment is mainly composed of a purifier, a fixing device for the purifier, and an air delivery conduit. Among them, the filter material used for filtering, the air delivery conduit and There is a certain degree of defect in the air delivery method. [0003] For filter materials, in order to save the space of personal air purification equipment, existing personal air purification equipment adopts single-layer filter pap...

AI Technical Summary

Problems solved by technology

First of all, the diameter of the ventilation pipe in the actual catheter of this type of catheter is small, and the ventilation efficiency is not high, while the power to drive the air flow in the tube in the personal air purification system is effective, and the narrow ventilation cavity will obviously make the ventilation effect low; The ventilating ducts are usually directly threaded or socketed on the purifier or related equipment (such as masks) for air outlet, which makes the assembly and disassembly of the equipment very cumbersome, and the assembled effect is similar to a gas mask, which is very unsightly; again , the length of traditional medical plastic or rubber catheters cannot be stretched and adjusted, and can only be cut quantitatively, which is very inconvenient to adjust the length of the ventilation pipe; more importantly, when personal air purification equipment is worn on the human body, the ventilation pipe and purifier There is a certain bending angle between the ventilation pipe and the gas delivery device (such as a mask), and when in use, the bending angle of the catheter is too small to directly reduce or even eliminate the ventilation volume, causing great inconvenience

[0005] For the air supply method, traditional personal air purification equipment includes a mask or face mask for air delivery, and the connection method adopts the mode of a sterile mask, and a vent hole is set in the front or middle of the mask or face mask (note that the mask or face mask except for the vent hole Other parts outside can not pass through the air), and the vent hole is connected to the air duct. This connection method is not only unsightly, but also hinders the front line of sight when used. More importantly, this kind of mask or mask itself has poor air permeability or airtight Completely, once there is a problem with the air supply system, such as power shortage, fan failure, or complete bending and blocking of the air supply duct, it will cause a certain degree of air supply shortage, resulting in increased suffocation, and even hypoxia and suffocation risks in severe cases
