A docking station for a robotic vacuum cleaner has a pneumatic transfer mechanism that is used to direct air to the robotic vacuum cleaner to thereby transfer dirt from the robotic vacuum cleaner to a docking station.

Particles in an accommodation chamber are also easily discharged while facilitating replacement of an atmosphere in the accommodation chamber with an inert gas. An EFEM includes a load port 4, a housing configured to define, in the housing, a transfer chamber closed by connecting the load port 4 to an opening provided in a partition wall, a supply pipe for supplying nitrogen to a transfer chamber, and a discharge pipe 49 for discharging a gas in the transfer chamber. The load port 4 includes an opening/closing mechanism 54 capable of opening and closing a lid 101 of a mounted FOUP 100, and an accommodation chamber 60 kept in communication with the transfer chamber via a slit 51b and configured to accommodate a part of the opening/closing mechanism 54. The discharge pipe 49 is connected to the accommodation chamber 60 to discharge the gas in the transfer chamber via the accommodation chamber 60.

An air purifier capable of adjusting wind directions according to an embodiment of the present invention comprises: a housing having an air outlet port on one side thereof; an air guide having a front end portion disposed at the center of the air outlet port such that the air outlet port becomes a ring shape and a rear end portion extending in a direction toward the other surface of the housing and coupled to the inside of the housing so as to be rotatable in a direction inclined with respect to the air release direction of the air outlet port; and a rotation-restraining portion for restraining the rotation of the air guide by elastically supporting the air guide on the housing.

An air purifier (100) includes a housing (400) formed with an air duct (401), an ozone generation device (20), an activated carbon purification unit (80), and a fan (200) arranged in the air duct (401). The air duct (401) includes an air inlet (402) and an air outlet (403). The air outlet (403) is disposed indoors. The ozone generation device (20) and the activated carbon purification unit (80) are arranged in the air duct (401) along the direction of the air inlet to the air outlet (403), and the ozone generation device (20) is used to generate ozone. The fan (200) is used to suck gas from the air inlet (402) during operation and let the gas pass through the ozone generation device (20) and the activated carbon purification unit (80) to be discharged from the air outlet (403) into the room.

This application provides an air purifier, which includes a casing, a fan, a filter, and a purification module. The filter is in a cylindrical shape. The purification module includes an inner filter for purification of harmful gases in air. The inner filter includes an inner filter cylinder and a purification plate, the purification plate and/or the inner filter cylinder are honeycomb-like or reticulate, and the inner filter cylinder is disposed in the filter. In the present application, the air purifier is provided with an inner filter to remove harmful gases such as formaldehyde in the air, and the purification plate and/or inner filter cylinder are honeycomb-like or reticulate to reduce wind resistance of the inner filter and reduce air resistance, thereby reducing the fan speed and noise.

This application provides an air purifier, which includes a casing, a fan, a filter, and a photocatalytic module. The filter is in a cylindrical shape. The photocatalytic module includes a photocatalytic cylinder having a cylindrical shape and a light source for irradiating the photocatalytic cylinder. The photocatalytic cylinder is disposed in the filter, an upper end of the photocatalytic cylinder is supported in the casing, and the light source is installed in the casing. In the present application, the air purifier is provided with a photocatalytic module which can decompose harmful gases and enables a sterilization, thus the purification performance can be improved. The filter and the photocatalytic cylinder both have a cylindrical shape, and the photocatalytic cylinder is disposed in the filter.

An apparatus and method for inactivation of airborne pathogens to include a reactor space with an intake opening, an exhaust opening, and an airflow path disposed between the intake and exhaust openings for air to continuously transit throughout the reactor space. The apparatus also includes at least one of (i) a corona discharge unit with a pressure swing adsorption unit, or (ii) a UV-C germicidal lamp to generate a sufficient concentration of ozone and UV light to inactive pathogens. The apparatus also includes a catalyst disposed within the path of the airflow to convert ozone to oxygen following the inactivation step and an adsorbent to remove nitrogen oxides from the air. The apparatus also includes sensors for measuring ozone and nitrogen oxides concentrations at the exhaust opening.

An air management system for a common indoor room or space that comprises a plurality of air outflow apertures or vents, a plurality of air curtains having at least a portion of the air curtains separated from one another, a plurality of separated air suction intakes, and an air sterilization and/or air cleaning mechanism.

A composite media alternative to high pressure drop glass microfiber HEPA media for use in applications where HEPA efficiency with an oily aerosol challenge with low resistance are required. The composite media contains two light filtration layers, one or both of which is charged, and the efficiency of the material can be greatly increased over a single layer containing the same weight of material. The composite media contains a backer layer to provide mechanical support to the filtration layers.

A food waste disposer including a housing, a container disposed inside the housing and provided to accommodate food waste, an exhaust duct communicating with the container and provided to allow exhaust gas generated in the container to flow therein, a filter device including a catalytic filter part configured to filter the exhaust gas passed through the exhaust duct, and a deodorizing filter part configured to filter the exhaust gas passed through the catalytic filter part and communicating with an outside of the housing, and a condensation chamber configured to remove moisture in the exhaust gas flowing from the exhaust duct into the catalytic filter part of the filter device.
