An apparatus for inactivating bioaerosol, comprising an enclosure having lumen walls forming a lumen, said lumen having a lumen input opening and a lumen output opening; a ventilator arranged for forcing an air flow through said lumen; in a cleaning section of said lumen, a source of ultraviolet light arranged to irradiate with ultraviolet light all the air passing through said lumen along a length of said cleaning section; an output muffler arranged for reducing a noise of said air flow in output of said lumen output opening; and a downstream turn section of said lumen, downstream said cleaning section of said lumen, arranged for changing a direction of said air flow such that no ultraviolet light in said cleaning section of said lumen is detectable at said lumen output opening.

An ionizing device is described, comprising a tubular bulb made of electrically insulating or dielectric material extending along a longitudinal reference axis and having the two longitudinal open ends and opposite each other, a tubular cathode engaged in the bulb, a tubular anode fitted to the bulb, a pair of covers, each of which has a respective internal seat into which a respective end of the bulb is inserted so as to hermetically seal it, and a conductive electrode which extends into the bulb and is electrically connected to the cathode.

A recirculating warm air system configured to connect to an air inflatable product is provided. The system includes a first chamber and a second chamber. The first chamber includes a first air inlet and a first valve located at the first air inlet. The second chamber includes a second valve located between the first chamber and the second chamber, an air outlet, and a first hose connected to the air outlet. The second chamber further includes an air blower and a heater located between the air blower and the air outlet. The second chamber includes a second air inlet, a third valve located at the second air inlet, and a second hose connected to the second air inlet. The first hose and the second hose are configured to connect to the air inflatable product. The system further includes a processing unit configured to control elements of the system.

Disclosed in an air purification device comprising a case that contains at least a first filtering system including an M6 filter according to standard EN1822, a second filtering system including UV-C lamps, and a third filtering system. The second filtering system is situated between the first filtering system and the third filtering system, the UV-C light of the lamps sterilising the air flow that passes through the second filtering system. The UV-C light of the lamps has a powerful destructive effect on the DNA chains of microorganisms or cells retained in the first filtering system and the third filtering system and also on those of microorganisms or cells in the space delimited between the first filtering system and the third filtering system.

The present invention discloses a purifier, including a purifier body and a filter unit arranged in a purification chamber of the purifier body. A side wall of the purification chamber has an opening to which a cover is mounted. The filter unit is an integrated filter and disinfection body, which includes a filter body and a disinfection body which are detachable from each other. The filter unit is mounted inside the purification chamber and electrically connected to the purifier body to supply power to the disinfection body. According to the arrangement of the filter and disinfection body in the present invention, the disinfection body and the filter body are collectively designed into one integrated structure, so that the disinfection body and the filter body can be mounted inside or removed from the purifier body as a whole, which is convenient and fast. In addition, the disinfection body and the filter body in the present invention are assembled in a detachable manner, so that the disinfection body and the filter body can be replaced, repaired and maintained separately, and the long-term use costs of users are greatly reduced, thereby solving the technical problem existing in the related art.

An air purifier having a side-access or horizontally-removable air filter assembly may include a housing, a base plate, a filter plate, a filter, and an air blowing unit. In some configurations the air purifier also includes a UV-light source and a removable covering or panel. Once the removable cover is separated from the housing, the filter plate with the filter assembly may be slid horizontally into and out of the housing. Once the filter plate, filter, and UV-light source are removed from the housing, the filter may be replaced, cleaned, and/or inspected.

The device for releasing volatile substances comprises a support (9) for positioning a receptacle (3) containing the volatile substances, and means for generating a flow of air for releasing the volatile substances, and which is characterized in that said means for generating a flow of air comprise a mobile body (1) joined to said support (9), at least one magnet (2) disposed in said mobile body (1), and means for generating a magnetic flux (4, 5), the operation of which causes the movement of said mobile body (1) by means of the repulsive force between the at least one magnet (2) in the mobile body (1) and the magnetic flux.

An improvement in the energy consumption is permitted, using a low-consumption periodic operation, aided by magnetic means.

The mixing nozzle has a throat section, a diffuser section, a gas nozzle section, a first liquid suction port, a liquid nozzle section, a second liquid suction port, a baffle plate, and a jetting port. The first liquid suction port liquidly absorbs the solution in the water storage pool from a side of the gas nozzle section toward the gas nozzle tip. The liquid nozzle section extends to the downstream side of the gas nozzle section with intervening the first liquid suction port. The second liquid suction port liquidly absorbs the solution in the water storage pool from a side of the liquid nozzle section toward the liquid nozzle tip. The baffle plate is provided such that the mixed flow mixed in the diffuser section collides in front of a downstream end of the diffuser section, and divides and reverses the mixed flow.

An ionizing device is described, comprising a tubular bulb made of electrically insulating or dielectric material extending along a longitudinal reference axis and having the two longitudinal open ends and opposite each other, a tubular cathode engaged in the bulb, a tubular anode fitted to the bulb, a pair of covers, each of which has a respective internal seat into which a respective end of the bulb is inserted so as to hermetically seal it, and a conductive electrode which extends into the bulb and is electrically connected to the cathode.

An ionising device is described comprising a tubular bulb of electrically insulating or dielectric material extending along a longitudinal reference axis and having the two opposite longitudinal terminal ends and open, a tubular cathode engaged in the bulb, a tubular anode fitted onto the bulb, a pair of covers coupled to a relative end of said bulb so as to hermetically close it, and a conductive electrode comprising a stem extending into said bulb, and a plurality of conductive crowns which are fitted onto the stem at predetermined distances from each other and are suitable to exert an elastic compression on the tubular cathode against the inner surface of the bulb.
