To provide a toilet roll having a deodorizing function. The problem is solved by a toilet roll in which a volatile deodorizing fragrant agent that is vaporized to emit fragrance and chemically deodorizes a malodorous component is applied to an outer periphery of a paper tube, and a deodorizing region to which a deodorant that chemically deodorizes a malodorous component is applied for deodorizing a malodorous component by contact with the malodorous component is provided on an inner periphery of the paper tube.

A robot for atomization and disinfection is provided, which includes a robot body, an aerosol generator arranged outside the robot body for spraying aerosol mist particles into air, an aerosol concentration detector arranged outside the robot body for detecting an aerosol concentration in the air, and a main controller arranged inside the robot body and connected to the aerosol generator and the aerosol concentration detector for controlling a spray volume of the aerosol mist particles in real time according to the aerosol concentration after the aerosol generator sprays aerosol mist particles into the air. The aerosol concentration is dynamically monitored in real time, and the sterilization aerosol is supplemented in real time according to the concentration change, so as to maintain the stability of the concentration of the sterilization aerosol, improve the intelligence of space disinfection for epidemic prevention, and reduce the burden of manual disinfection.

Aspects disclosed herein include a system for generating singlet oxygen in a gas, the system comprising: a substrate; and hexanuclear clusters operably immobilized on at least a portion of the substrate; wherein each hexanuclear cluster comprises a photosensitive octahedral core complex characterized by formula FX1a: M.sub.6X.sub.8 (FX1a); wherein each M is independently Mo, W, or Re; wherein each X is independently a halide anion ligand; wherein the clusters are exposed to the gas and the gas comprises O.sub.2 gas; wherein the clusters are exposed to a light; and wherein each hexanuclear cluster is a photosensitizer configured to generate the gaseous singlet oxygen when irradiated by the light in the presence of the O.sub.2 gas.

Aqueous compositions of one or more organoethoxysilanes dissolved in an aqueous solution with one or more alcohols, polyvinyl alcohol and one or more optional fragrances, which can present or eliminate malodor aroma from microogranisms, methods of preparing the mal-odor removing compositions, and/or methods of using the mal-odor removing compositions. The mal-odor removing aqueous compositions preferably being in an liquid form that leaves is capable of providing clear, dried coating or film upon applied surfaces that removes odors and prevents proliferation of odor causing bacteria, fungi and viruses.

The present invention generally relates to a safe steady portable incense heater and, more particularly, to a self-contained incense heater shaped as a trapezoid hexagon inflated from bottom for safely holding, igniting, and heating incense (bukhoor wood bricks). The safe steady portable incense heater shaped as a trapezoid hexagon inflated from bottom heats the incense (bukhoor wood bricks) to a specific temperature in order to help the user direct the smoke flow in the exact direction of the nozzle using the fan thrust. The self-contained safe incense heater shaped as a trapezoid hexagon inflated from the bottom has a small hand size and is portable without any wires to enhance the mobility of the users and the way of using incense or bukhoor wood bricks.

A ventilation seat of a vehicle is proposed. The ventilation seat includes a ventilation pipe mounted in a seat of the vehicle and configured to suck indoor air and to discharge air toward a surface of the seat, a catalytic converter provided in an air flow path of the ventilation pipe, and configured to clean air passing through the air flow path when light is emitted, and a light source assembly provided on an inner wall of the air flow path of the ventilation pipe and arranged to face the catalytic converter to emit the light toward the catalytic converter.

The present invention relates to a carbon-based material for use in a piece of personal protective equipment and an air filtration system. The carbon-based material may function as a filter by providing a tortuous path for a pathogen to traverse. The carbon-based material may be used as a carbon-based heater that can reach a pathogen inactivation threshold temperature to enable heat inactivation of one or more pathogens. In embodiments where a piece of personal protective equipment includes a carbon-based heater, an insulating layer may be included to attenuate the temperature generated by the carbon-based heater from the face of a user.

A small, reusable scent emitting device (FIG. 1 and FIG. 6), attachable to a variety of mask types (FIG. 5), with interchangeable reservoirs for use with multiple different scented liquids (2), connected to a flexible directional extremity trim able to needed length dictated by wearer use and mask type (FIG. 1, FIG. 4 and FIG. 6), and whose manufacture is distinct from any particular mask type.

An open-cell foam structure that is used to detect and remove substances from water or air.

A method for detecting and filtering indoor polluted gas includes providing a plurality of gas detection devices to detect the polluted gas in an indoor space; providing a plurality of filtration and purification devices to filter the polluted gas and to receive a first control command through a wireless communication to enable filtration of the polluted gas; and providing a connection device to perform intelligent computation to receive and compare the data of the polluted gas detected by the gas detection devices to perform intelligent computation to figure out a location of the polluted gas and intelligently and selectively transmit the first control command to a filtration and purification device which at the location of the polluted gas, thereby filtering the polluted gas and retaining the polluted gas from spreading outwardly, allowing the polluted gas in the indoor space to become a clean, safe, and breathable gas.
