The present application discloses an air purifier, including: a first body including a first housing; and a second body detachably connected to the first body and including a second housing, where buckles are arranged on the first housing, and snap-fit members are arranged on the second housing; the number of the buckles is greater than the number of the snap-fit members; and the first body in butt joint is enabled to rotate relative to the second body, so that the buckles can be hooked with the snap-fit members or separated from the snap-fit members. In the air purifier, a larger number of buckles are hooked with a smaller number of snap-fit members, so that disassembly and assembly operations can be simplified. Because the first body and the second body are detachable, the second body can be operated independently when the filter screen is detached.

An object of the present invention is to provide a safety cabinet that allows a clearer observation of contamination of an operation stage surface. In order to realize the object, the safety cabinet is configured to include an operation space including an operation stage; a front panel formed in a front surface of the operation space; an operation opening provided in a lower portion of the front panel; a suction port that is provided in the vicinity of the operation opening on a front side of the operation stage to lead downward; and an air circulation path through which air suctioned from the suction port flows along a lower portion, a back surface, and an upper portion of the operation space, in which the operation stage is made of a transparent material, and a light source is provided to irradiate the operation stage with a light from a side of the operation stage, which is opposite to the operation space.

The subject matter is the assembly of a containment means with an aseptic working chamber and associated decontamination arrangement. The working chamber is delimited at the bottom by a base, and above the working chamber is a circulating air zone, in which a circulating air filter with a circulating air fan is arranged. The circulating air zone and the working chamber are delimited towards the outside by a housing. At least a first returning air channel leads from the working chamber into the circulating air zone. A returning air filter is fluidically connected to the returning air channel, specifically is arranged facing the circulating air zone. The returning air filter can be arranged at the opening of the returning air channel into the circulating air zone or arranged in the circulating air channel, set back from the opening. The returning air filter and the circulating air filter are in the form of a plate filter or an exchangeable filter cartridge or a replaceable filter insert. A single returning air filter or a series of interacting returning air filters and a single circulating air filter or a series of interacting circulating air filters can be installed. Containment means in which larger volumes of air are to be processed also have a second returning air channel at or in which a returning air filter is also installed.

An air cleaner disposed in an indoor space is disclosed. The air cleaner according to an embodiment of the present invention includes a blowing device including a suction port and a discharging port, a fan motor configured to cause air flow, a purification unit installed in the blowing device to clean air, a flow conversion configured to change a flow direction of air discharged from the discharging port, a communication unit configured to communicate with a moving agent moving in the indoor space, and a processor configured to receive feature information collected by the moving agent and associated with a structure of the indoor space, obtain a type of the indoor space by using the feature information, and control an operation of at least one of the fan motor and the flow conversion device by using the type of the indoor space to adjust at least one of an operation mode, a wind direction, and a wind volume.

An air cleaning module includes a filter, a fan, a light source unit, a housing and a guide structure. The fan is configured to provide a suction direction and a blowing direction of a fluid which are substantially aligned. The light source unit is arranged to be adjacent to the filter to emit a light toward the filter. The light having a property that sterilizes a contaminant source in a fluid. The housing includes a fluid passage space. The guide structure is arranged between the fan and the filter and configured to guide a fluid to move along a fluid passage path set by the guide structure. The filter and the light source unit are arranged in the fluid passage space such that the light source unit sterilizes a fluid as a fluid flows toward the light source unit.

An air purifier includes a housing, a first blower, a second blower, and a filter. The housing has a cavity inside, an inlet and an outlet. The first blower has a first fan in the housing. The second blower has a second fan in the housing. The second blower faces the first blower in an opposing direction. The inlet is located between the first blower and the second blower in the opposing direction. The inlet opens in a direction intersecting the opposing direction. The first fan of the first blower and the second fan of the second blower generate airflow such that air flows into the cavity through the inlet, and flows from the cavity through the filter to the outlet.

The present disclosure relates to fine filter part kit (63), comprising a replacement fine filter part (15) that is adapted to be mounted to a fine filter section (12) for a dust extractor (1). The fine filter part kit (63) further comprises a filter lid (16) that is adapted to be mounted to a corresponding used fine filter part (15) to be replaced, already mounted to the fine filter section (12), and thereby seal an opening (28) of a particle containing space inside the used fine filter part (15) before removing the used fine filter part (15). In this way, release of particles contained in the particle containing space into the ambient air is prevented and a secure disposal of the used fine filter part (15) is enabled.

An exhaust fan for preventing air pollution includes a main body and at least one gas detection module. The main body is configured to form an airflow-guiding path and includes a gas guider and a filtration and purification component disposed in the airflow-guiding path. The gas guider introduces an air convection for guiding an air pollution source contained in an air to pass through the filtration and purification component so as to filter and purify the air pollution source. The at least one gas detection module is disposed in the airflow-guiding path for detecting the air pollution source and transmitting gas detection data.

A vacuum cleaner for air pollution prevention includes a main body, a blower, a filtering and cleaning assembly, and a gas detection module. The main body is configured to form a flow-guiding path. The blower is disposed in the flow-guiding path to guide air convection. The filtering and cleaning assembly is disposed in the flow-guiding path to filter and clean the air pollution source in the air guided by the blower. The gas detection module is disposed in the flow-guiding path to detect the air pollution source and transmits a gas detection data.

A handheld air purifier may include a suction body provided with a suction surface having a first and second frame, a fan to suction air, and a filter to filter suctioned air, a bending portion extending rearward from the suction body to bend upward, and a handle extending further from the bending portion and held by the user. The second frame may be provided behind the first frame and may include a protrusion that penetrates through the first frame to create a gap between the suction surface and a garment being treated to promote a free airflow through the handheld air purifier.
