Description

Wearable Invisible Air Purifier

1. Technical field

The invention relates to a wearable air pollution-proof invisible air purifier, which is a personal wearable device specially used for personal respiratory system to prevent air pollution, harmful gas or fire protection.

Two, background technology

At present, there are many kinds of air purifier equipment or supplies used to prevent smog hazards at home and abroad. According to the three types of indoor, outdoor and vehicle-mounted, there is still no one that truly adapts to personal freedom of movement, clear breathing channels, and can be worn invisible. An air purifier that fully utilizes clean air.

The basic characteristics of existing various types of air purifiers or portable anti-air pollution products are: people are active outdoors, mainly relying on the current various masks, only eyes are exposed, breathing is blocked, speech is limited, the face is covered, and carbon dioxide gas is exhaled. Re-inhalation forms secondary (circulation) pollution, insufficient clean air or oxygen supply; in a specific indoor environment, such as a dusty, odorous working environment, the air purifier is affected by indoor space, air flow, air medium, maintenance and repair. and other effects, the use efficiency is greatly reduced; the vehicle-mounted air purifier is limited to the use in the car, which is equivalent to the indoor environment. The current various types of air purification equipment or supplies are freely and efficiently used by people, all of which are limited by the volume of equipment, the amount of clean air, and the selection of breathing channels. They are not suitable for people's free activities, and the utilization rate of clean air is low. All kinds of popular masks or face masks have not gone out of the misunderstanding of basic physiological common sense in ergonomics that "the nostrils and the mouth are responsible for breathing" in the selection of breathing channels. "Wearing a mask to prevent air pollution (smog)" In fact, it is a specious and headache thinking inertia, which is contrary to the basic principle in ergonomics and environmental engineering that people inhale oxygen and exhale carbon dioxide through the nostrils to maintain life.

Three, the content of the invention

In view of the above-mentioned problems and situation analysis, the present invention takes "human-machine-environment" coordination and high efficiency as the basic concepts, integrates the principles of ergonomics, the principle of "weak current technology drive + PID control", and the principle of environmental engineering. The direct connection of the breathing passage, the one-time use of clean air, and the miniaturization and invisibility of the structure and function have been designed with a new concept of air purifiers, making it personalized, compatible, and aesthetically pleasing, allowing more people from ten In the face of "smog", you can freely breathe higher quality clean air, or actively prevent respiratory diseases.

The technical solution adopted by the present invention to solve its technical problems is as follows:

A wearable invisible air purifier composed of a filter element, a coat, and a nasal mask. It is characterized in that: the HEPA filter cover of the filter element is built into the coat, and the two nasal plugs at the head end of the Y-shaped nasal mask trachea are directly connected to the two nostrils of the person. , the outlet at the end of the trachea is connected to the filter element in a plug-and-play manner, and the jacket is a wearable accessory for the human body.

The present invention is also characterized in that the filter element is composed of HEPA filter cover, turbofan, and external power supply to form a split structure. The turbofan is nested in the HEPA filter cover to form a micro filter, and its side is provided with a suction valve outlet and an external power supply. interface, the turbofan is connected to an external power supply to form a split type weak-level fan system, and the external power supply is a current general-purpose weak-level rechargeable battery.

The present invention is also characterized in that: the built-in turbofan of the filter core and the external power supply form a split micro fan with a power less than 1W. When the fan is powered on and started, the negative pressure of the turbofan sucks a certain proportion of air, which affects the air volume and wind speed sucked into the HEPA filter cover. PID control is carried out in proportion to the ratio required for nostril inhalation to complete the dynamic balance between the initial resistance and final resistance of filtered air, and the resistance difference tends to 0, achieving the balance of supply and demand and comfort of normal human breathing.

The present invention is also characterized in that the jacket is an ornament that is nested in the outer layer of the HEPA filter cover of the filter element and can be worn by the human body. It has the functions of air purification and body invisibility while highlighting the individual aesthetic design, so that the overall structure of the purifier becomes a headgear, hair The miniature design elements of various personal accessories such as necklaces, collars, clothing, and spectacle frames are rich in variety and more in line with individual aesthetic pursuits.

The present invention is also characterized in that the nasal mask is composed of four parts: an interface, a trachea, a left nasal plug, and a right nasal plug. There are two left nasal plugs and right nasal plugs with the same structure. The plug mouth of the nasal plug is in the shape of a flexible gourd mouth with mesh to maintain air tightness and elastic connection with the nostrils. When inhaling or deactivating, the plastic sheet exhalation valve is in a sealed state because of its elasticity close to the top of the safety barrier, so that unfiltered purified air cannot enter the nostrils from above the safety barrier, that is, the exhalation valve ensures that the exhaled carbon dioxide gas is one-way Sex can only go out but not in.

The above-mentioned nasal mask integrates the principles of ergonomics and environmental engineering to liberate the face and mouth that have nothing to do with breathing, so as to meet the requirements of people's physical and mental activities and achieve the best use efficiency. The goal is safety, health and high efficiency. And comfortable, easy to be invisible and wearable, the Y-shaped transparent one-way ventilation hose made of medical-grade PVC (polyvinyl chloride) material has invisible and fully enclosed ventilation effects, ensuring that the filtered clean air is one-way from inhalation to exhalation Sexual flow, the exhaled carbon dioxide will not be repeatedly inhaled to form secondary air pollution due to the cover.

The filter screen that meets the HEPA standard has an efficiency of 99.7% for 0.1 micron and 0.3 micron. The particle removal efficiency can reach more than 99.97%, and it is the most effective filter medium for pollutants such as smoke, dust and bacteria. According to the method specified in GB/T6165-1985 "High Efficiency Air Filter Performance Test Method Transmittance and Resistance", the transmittance is ≤0.1% (that is, the efficiency is ≥99.9%) or the counting penetration of particles with a particle size of ≥0.1μm Filters with pass rate ≤0.001% (that is, efficiency ≥99.999%) are high-efficiency air filters.

The above-mentioned PID control means that the air volume and wind speed inhaled by the turbofan in the filter element are in a dynamic ratio to the air volume and frequency required by the normal natural respiration of the human body, that is, the air volume and wind speed may be too strong or too weak. For the discomfort caused, the turbofan is set as a miniature turbofan with a power less than 1W. When it is working, the negative pressure of the inhalation is only to overcome the resistance generated by the air filtered by the HEPA filter cover, so that the resistance difference of air inhaled into the human body is 0. To achieve natural balance, in line with the normal frequency of human natural breathing.

The above-mentioned nasal plug mouth is a flexible gourd mouth with mesh to maintain air tightness and elastic connection with the nostrils. The upper end of the plug mouth is provided with a safety barrier and an elastic plastic sheet exhalation valve. When inhaling or inactive, the plastic sheet exhales The valve is in a sealed state because of its own elasticity and close to the top of the safety barrier, so that the unfiltered purified air cannot enter the nostrils from above the safety barrier, that is, the exhalation valve ensures that the exhaled carbon dioxide gas can only go out in one direction.
