Description

Technical Field

[0001] The present invention relates to the field of air purification, and in particular to a whole-piece wearable air purification device. Background Art

[0002] There are a variety of respiratory purification devices available on the market, including non-woven masks, N95 masks, dust masks, and gas masks. However, these devices have drawbacks such as low dust protection efficiency, resistance to inhalation and exhalation, insufficient air flow during intense breathing, environmental issues related to waste, a single filter function, discomfort caused by prolonged wear, poor airtightness, and a lack of moisture and heat dissipation, resulting in hot summers and cold winters. There are also portable personal air purifiers, which consist of a protective mask, purifier, air supply, and mounting devices. These devices, however, utilize a high-pressure air pump, which in turn changes the pressure within the cylinder to inhale and deliver air. The air supply connects the protective component to the purifier, allowing external air to pass through the purifier and be purified. The air supply then delivers the purified air to the protective mask, which rests on the wearer's face, allowing the wearer to breathe fresh air. The above-mentioned traditional portable personal air purifiers have at least the following disadvantages: First, the traditional purifiers are driven by a high-pressure air pump and use a filter system pressurized by the air pump to purify the air, which is inefficient and cannot meet the user's normal breathing volume of air; second, the use of a high-pressure air pump is driven by it, which is noisy and heavy, making it inconvenient for users to carry and move; third, except for the protective mask on the user's face, the entire device only provides the user with air that is relatively clean compared to the outside air, and cannot achieve a protective function; especially in hot summers or cold winters, when people shiver in the cold and sweat in the hot and humid, the intake air is easily atomized after breathing; some have unstable air pressure in the hood; some can only be used for a short time; some cannot communicate with the outside world; some are inconvenient to put on and take off several pieces; and they always fail to meet the needs of users.

[0027] Furthermore, the outer frame 11 is a spherical transparent outer frame, which is injection molded and made of polycarbonate and acrylic resin. The spherical body adopts a semiconductor thin film process and imitates the surface concave and convex structure of the eyeball of a nocturnal moth with a 100-nanometer fine processing to reduce surface reflection. The reflectivity is less than 0.25%; the spherical body is 4 mm thick and has a light transmittance of more than 99.99%.

[0028] Furthermore, the clean air guide plate 13 is formed by injection molding and is made of polycarbonate with a thickness of 4 mm.

[0029] Furthermore, the stretchable airtight neck collar 12 is in the shape of a circular collar, and is made of glass fiber cloth coated with silicone rubber on the inside. It uses high-temperature resistant, corrosion-resistant, high-strength glass fiber cloth, which is calendered or impregnated with silicone rubber.

[0040] Furthermore, the constant temperature air conditioner 39 includes a refrigeration unit and a heating unit. The refrigeration unit adopts a semiconductor electronic refrigerator, which uses the extremely high thermoelectric potential of semiconductor materials as a small thermoelectric refrigerator, 12V120W, and dimensions of 100 mm x 120 mm x 150 mm; the heating unit adopts a ceramic electric heater for temperature control heating, 12V100W, and dimensions of 10 mm x 30 mm x 30 mm; alumina ceramic is a new type of high-efficiency, environmentally friendly and energy-saving MCH ceramic heating element device, which uses high thermal conductivity alumina ceramic as a matrix and heat-resistant refractory metal as an inner electrode to form a heating circuit, and has the advantages of no surface charge, small size, high power density, fast heating rate, high thermal efficiency, good safety, insulation and voltage resistance, long service life, good acid and alkali resistance, stable power, no harmful substances, and resistance to dry burning; the constant temperature air conditioner 39 series performs the constant temperature control function through an intelligent control module.
