A method and a system for generating a fragrance (also referred to herein as perfume) are disclosed. A method may comprise providing a perfume blender machine (100) and cartridges (102) for storing liquid olfactory ingredients (112), the machine comprising dispensing means to dispense olfactory ingredients (112) from the cartridges (102) for generating a fragrance (114); controlling the dispensing means to generate a fragrance (114) based on instructions given by a user on the liquid olfactory ingredients (112) to be blended and the quantity of each; and generating a recipe with the information of the ingredients (112) and their respective quantities which have been used to generate the fragrance.

The invention relates to automated devices for pro¬ducing aerosols of liquid disinfectants and for spraying same. A mo¬bile hygiene unit comprises a housing (1) containing a disinfectant spraying unit (2) with a spraying nozzle (3), a tank (4) containing disinfectant, a compressor (5), and a control unit (6). It further com¬prises a mechanism for regulating the droplet size distribution of the aerosol, including a pump (7), an electromagnetic valve (8), and a dosing nozzle (9) with an internal cylinder. The disinfectant spraying unit (2) comprises a shaped nozzle (3) having a nozzle head (10) of axisymmetric cross-section attached thereto, and a mixing chamber (11) for mixing disinfectant with compressed air, having two thread¬ed inlets for a pneumatic line (12) and a hydraulic line (13), said inlets being arranged at an angle of 180°. The dosing nozzle (9) contains an internal cylinder and a rod with a threaded tip. The mobile hygiene unit generates an aerosol in four droplet size distribution modes: dry fog (from 3.5 to 10 pm), wet fog (from 10 to 30 pm), mist (from 30 to 50 pm), and spray (from 50 to 100 pm). The invention allows highly precise regulation of the droplet size distribution of the aerosol in each mode without the need to change the spraying nozzle.

A sterilization air conditioner is provided in this disclosure, which includes an indoor unit and a sterilization device. The sterilization device is arranged on the indoor unit, and the sterilization device is configured for sterilizing the air entering the indoor unit and a body of the indoor unit by releasing chemical or physical media. In view of a structure of the air conditioner, a front end of a filter screen of the air conditioner is equipped with a disinfectant dripping, drenching, sprinkling, spraying or atomizing or a plasma or ultraviolet or electrostatic negative oxygen ion sterilization device, and disinfectant or plasma or ultraviolet or negative oxygen ion is sprayed to the air conditioner for sterilization. The disclosure has advantages of simplicity, convenience and low investment, and is more suitable for sterilization of household split air conditioners and central air-conditioning fan-coil air conditioners.

Methods, systems, and devices are disclosed for implementing switchable dispensing and/or delivery of scented substances. In one aspect, a device includes a cartridge structured to include one or more chambers containing one or more scented substances contained in a corresponding chamber, a housing structured to include a compartment to hold the cartridge, an opening to allow the scented sub stances to dispense to an outer environment from the device, and one or more transporting channels formed between the compartment and the opening, in which each of the one or more transporting channels is configured to accelerate a scented substance from the corresponding chamber to the opening, and an actuator switch arranged in a corresponding transporting channel and operable to move between an open position and a closed position based on an applied signal to selectively allow passage of the scented substance from the corresponding transporting path.

Various fragrance dispensers are disclosed. The fragrance dispenser can include a core unit that has a connection unit and a control unit. The fragrance dispenser can include a cartridge that is configured to engage with the core unit. The cartridge can include an impeller and a fragrant material. The fragrance dispenser can have a motor that drives the impeller, thereby dispersing the fragrance. The cartridge can be configured to disengage from the connection unit, such as when the cartridge reaches a depleted state.

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 system includes a plurality of carbon dioxide sensors each located in one of a plurality of spaces in a building and a plurality of air purification systems each located in one of the plurality of spaces and each including a UVC light source arranged within an internal space of a purification chamber and adapted to irradiate the internal space with UVC, an airflow system arranged to introduce environmental air from outside of the air purification system into the internal space of the purification chamber and expel purified air from the purification chamber back outside of the air purification system wherein each of the plurality of air purification systems is operable to purify air in response to an indication that an associated carbon dioxide sensor has sensed a level of carbon dioxide in excess of a predetermined threshold.

An air enhancing device (1) for disseminating molecules and/or other substances into the air is disclosed comprising a base frame (5) configured to be fixedly mounted in a wall, panel, or furniture of a human accessible space, in particular in an in-wall box or an in-wall cavity in a wall of a building; a cartridge holder (7) attached to the base frame (5) and configured to receive a removable cartridge, the cartridge being designed to contain a fluid substance; and a fan and/or microblower configured to draw air into the air enhancing device (1) and expel air containing at least a portion of the substance out of the air enhancing device (1) into the human accessible space; and/or an emission module attached to the base frame (5) in fluid communication with the cartridge and configured to distribute a portion of the fluid substance into the air.

The purpose of the art is to treat the air via an air treatment machine. The invention consists of a base; major connector; pcb; dc motor; motor/modified scotch yoke mount; and modified scotch yoke. The base supports a decorative housing which can be made by the end user. The “modified scotch yoke/motor mount” is fastened by screws and nuts to the major connector which is attached to the base also by nuts and screws. Electrical and mechanical moving parts are fixed to the major connector of the battery operated device.

Air is treated by the contents of an aerosol spray can. The aerosol can is inserted through the bottom of the air treatment machine and secured in place by the major bracket screw cap. Once the aerosol spray can's nozzle is depressed by the modified scotch yoke, a vertical spray mist is expelled through the opening at the top of the decorative housing, thus treating the air in the surrounding environment.

An essential oil diffuser including multiple diffuser channels. Each diffuser channel includes an air pump and a cartridge assembly. The cartridge assemblies are removable receivable within a chassis assembly of the diffuser.
