摘要： A helmet includes a helmet body and a gas detection and purification device. The gas detection and purification device in includes a body, a purification module, a gas-guiding unit, a gas detection module, and a power module. The gas detection module calculates the gas detection data obtained by the gas detection module so as to control the gas-guiding unit to start or stop operation based on the gas detection data. When the gas-guiding unit is in operation, the gas-guiding unit guides the gas into the body and to pass through the purification module for being filtered and purified to become a purified gas, and the gas-guiding unit discharges the purified gas out of the body to the nose portion, or the mouth portion, or both the nose portion and the mouth portion of the wearer for providing the wearer with the purified gas to breath.

摘要： Provided is an electrically active breathing mask. The mask contains conductive layers separated by insulating layers, the conductive layers being alternatingly positively or negatively charged. Air passing through one insulating layer is directed across the surface of a next charged layer, before flowing through a next insulating layer, and so on. Particles including virus in water vapor or sputum are evaporated as they contact alternately charged layers.

摘要： A personal air purifier is a portable device that eliminates all pathogens and particulates present in the air breathed by the user. The device includes a purifier housing, an air inlet, an air outlet, a metallic air path, an air ionizer, a power source, an air fan, and a controller. The purifier housing retains the metallic air path, the air ionizer, the power source, the air fan, and the controller. The air inlet and the air outlet are openings that allow airflow through the purifier housing. The air fan generates airflow through the purifier housing. The metallic air path and the air ionizer sanitize the airflow through the purifier housing. The power source provide the operating power for the air ionizer, the air fan, and the controller. The power source positively charges the metallic air path. The controller enables the selective control of the air ionizer and the air fan.

摘要： The present disclosure provides a filter cartridge for a facepiece respirator mask body. The filter cartridge includes a cover, a base, and a filter medium. The cover has a top surface, a cover sidewall, cover support elements, and an inhalation vent. The cover support elements extend downwardly from the top surface. The inhalation vent is located at least primarily in the cover sidewall. The base has a bottom surface, a base sidewall, base support elements, and an inhalation port. The base support elements extend upwardly from the bottom surface. The inhalation port is located in the bottom surface. The base and the cover collectively define an interior compartment. The filter medium is sandwiched between the base support elements and the cover support elements in a manner that divides the interior compartment into an upper chamber and a lower chamber.

摘要： A personal neck-wearable device is configured to direct a curtain of protective air around the face of a wearer in use to prevent or reduce inhalation of airborne particles and pathogens. The air may be purified using filtration. In an embodiment, the air may be ionised using high voltage to ionise the air molecules with negative ions (anions) having one or more extra electrons, thereby negatively charging the air molecules. The curtain of ionised air molecules surrounds the face of the user and attracts airborne air particles by electrostatic attraction. These particles are then attracted to the nearest surface away from the mouth and nose to thereby reduce the likelihood of inhalation.

摘要： A filtering mask assembly includes a housing including a fan and an outlet valve. A filter is releasably mounted onto the housing and is adapted to substantially follow a shape and contour of the housing to seal the housing. A face seal is interposed between the wearer's face and the housing to provide a resilient conformity to the wearer's face when the mask assembly is worn. The mask assembly defines an inner space between the mouth and nose of the wearer and an inner side of the mask assembly, and an intermediate space between the housing and the filter and an outer space separated from the inner space by an outer side of the mask assembly. The fan is positioned on a downstream side of the filter to draw air through the filter. The mask assembly prevents the breathing of any air which has not passed through the filter.
