  • Publication number: 20220105226
    Abstract: The application discloses an air sterilizer. The air sterilizer includes a housing an ultraviolet light generator, and a reflector. The housing is provided with a first cavity, and the housing is provided with an air inlet and an air outlet, both of which are located at the first cavity. The ultraviolet light generator is also located in the first cavity. In the embodiment of the present application, an ultraviolet light generator is placed in the first cavity of the air sterilizer. The air flows in through the air inlet. When the air flows through the first cavity, it is sterilized by the ultraviolet light generator, and then flows out from the air outlet. The toxic or harmful substances in the air can be inactivated by ultraviolet light sterilization, which improves the sterilization and disinfection ability of the air sterilizer, and solves the problem of poor sterilization and disinfection effects of air sterilizers in the prior art.

  • Publication number: 20220054866
    Abstract: The present invention provides a mask. The mask includes a mask body, a filter module installed on the mask body, a light source and a photocatalyst plate. The filter module includes a cavity, and it is provided with an air inlet and an air outlet which are located in different regions of the filter module. The photocatalyst plate and the light source are both located in the cavity. The surface of the photocatalyst plate is covered with a photocatalyst coating, and the light emitted by the light source irradiates the photocatalyst plate. In the embodiment of the present invention, by placing the light source and the photocatalyst plate in the cavity of the filter module, the photocatalyst generates strong oxidizing substances under light irradiation, which substances can inactivate harmful substances. Therefore, by placing the light source and the photocatalyst plate in the cavity of the filter module, harmful substances entering the mask can be sterilized and inactivated.

  • Publication number: 20210393845
    Abstract: The present invention provides a photo-electronic air disinfector, which comprises a housing containing a fan, a UVC light source, a photocatalyst module consisting of a structure with entire surface area coated with a photocatalyst positioned by the side of the UVC light source, an air guide unit installed with reflecting mirrors on the internal walls of the unit. When air is drawn in the air guide unit of the device, the photocatalyst after absorbing UVC light emitted by the UVC light source or reflected through the mirrors generates superoxide (O2—) and hydroxyl radical (—OH) with strong oxidation power, which can decompose organic matter and various germs in the drawn in air and render them harmless.

  • Patent number: 7458481
    Abstract: A drink-item holding apparatus incorporates an upper flap and a lower flap which may be unfolded from a stowed configuration to a deployed configuration in which the upper flap is releasably latched in its horizontal position. Projections at the rear edge of the upper flap resiliently push in L-shaped arms against the biasing action of springs until the projections snap past the arms which then serve to latch the upper flap in its deployed configuration. The upper flap may be rotated in the reverse direction in order to unlatch the projections so as to return to the stowed configuration. The upper flap is therefore protected against inadvertent downward rotation. The lower flap folds away upwards, and the upper flap folds away downwards against the lower surface of the lower flap in order to produce a compact arrangement of the apparatus.

  • Patent number: 7364605
    Abstract: A photo-electronic air purifying disinfector firstly filters out airborne impurities using a washable filter screen. It then utilizes an activated carbon filter to filter out airborne bacteria and germs. The bacteria and germs which are capable of passing through the activated carbon filter are then eliminated by extreme-UV light emitted by extreme-UV light tubes. It also utilizes a negative ion generator to boost the level of anions in the air before being discharged. These two modes operate in the following manner: the first mode involves cathodic high-voltage output that is discharged via a carbonized fibre. The ionized air is then expelled by a fan. The second mode eliminates bacteria, germs and mould from air as it passes extreme-UV light tubes by exposure to extreme-UV light emitted by these extreme-UV light tubes.
