A device capable of stably obtaining gas of a sterilizer containing hydrogen peroxide for a long time is provided. A cleaning device that cleans a heating surface that gasifies a sterilizer of a gasifier for a sterilizer is provided, and after an operation for a fixed time period, the heating surface is cleaned.

This disclosure relates to a method for sanitizing a space. The method includes applying a composition containing triethylene glycol into a space containing a pathogen (e.g., a Staphylococcus, a Pseudomonas, a Listeria, Salmonella, Klebsiella, a Mycobacterium, a mold, or a spore) in an amount effective to inactivate the pathogen.

The present invention relates to a non-contact microplasma ozonized mist radical sterilizer. The present invention minimizes two discharge spaces to a micro size to lower a breakdown voltage, concentrates electromagnetic fields using micro-patterns to induce micro-discharge at a normal pressure, and generates plasma through glow discharge, to increase electron density and reduce power consumption according to generation of microplasma. When oxygen and air are injected as reaction gases using this principle, ozone is generated as active species, and the generated ozone is used for various purposes such as removing pests, reducing ethylene, and sterilizing harmful bacteria. Sterilization is improved by sterilizing air and generating mist using ozone generated from microplasma, and then decomposition and drying of ozone gas are performed using a heat generation device and a catalytic method.

A humidifier includes a heating element including a porous structure of electrically resistive and thermally conductive material configured to substantially vaporise liquid that is passed through the porous structure. The porous structure has a liquid inlet and a vapour outlet. The humidifier further includes an outer housing surrounding at least a portion of the porous structure for containing the liquid and vapour within the porous structure. The porous structure includes a first electrical connector and a second electrical connector, the first and second connectors being configured for receiving electrical power and applying a voltage across the porous structure to generate heat.

A portable deodorizing apparatus having: a housing with first and second releasably joinable parts; and a deodorant source. The first housing part has a first connector and the second housing part has a second connector. The connectors are configured to be: a) engaged so as to thereby maintain the first and second housing parts in an operative relationship as an incident of relatively moving the first and second housing parts from a starting relationship into the operative relationship; and b) disengaged as an incident of relatively moving the first and second housing parts with the first and second housing parts in the operative relationship, so as to thereby allow the first and second housing parts to be changed from the operative relationship into the starting relationship. With the first and second housing parts in the operative relationship, the deodorant source is maintained in an operative position wherein deodorant is diffused into a space within which the deodorizing apparatus is placed.

A portable sterilizer according to an embodiment of the present application is capable of spraying ultra-fine chemicals, and includes a housing in which a space is formed and an injection nozzle is provided at a front end thereof, a chemical tank provided on one side of the space of the housing, a chemical feed pipe formed between the chemical tank and the injection nozzle, and a water pump which is installed on one side of the chemical supply pipe to supply the chemical to the injection nozzle through the chemical supply pipe.

Apparatus, methods and instructions for disinfecting air. The apparatus may include, and the methods may involve, a fixture. The fixture may include a germicidal light source. The fixture may include a fan. The fan may circulate air through a volume into which the germicidal light source propagates germicidal light. The light source may be configured to emit, upward from a horizontal plane, a beam that, absent reflection off an environmental object, does not cross the horizontal plane. The apparatus may include a shield that prevents light from the light source from crossing the horizontal plane. The sensor may face upward from the horizontal plane. The sensor may face downward from the horizontal plane.
