Disclosed is a needle-type vibrate-to-nebulize apparatus and nebulizer for nebulizing fluids, in particular essential oils. The needle-type vibrate-to-nebulize apparatus mainly comprises the air passage designed in the module, the steel needle and the vibrating unit. Fluid is delivered from the rear end to the front end, then nebulized at the front end by high-frequency vibration. The nebulized mist is blown out through the air passage. The nebulizer mainly comprises the needle-type vibrate-to-nebulize apparatus and the peristaltic pump with rollers. The peristaltic pump with rollers is capable of sucking and supplying essential oil to the steel needle, as well as reversing the oil back when power off to prevent clogging. High-frequency vibrating action of the vibrating unit is generated by the piezoelectric disk and induced to the steel needle. As a result of resonation, essential oil is nebulized at the front end and blown out through the air passage.

Provided is a smart inhaler and wearable smart mask configured to operate as an air ionizer and a controlled multi-liquid atomizer. The smart mask and smart inhaler use a mature technology to deliver various types of liquid solutions to different applications from health care, drug delivery, immunization to recreational and gaming uses. In addition, the smart mask contains multiple actuators to provide haptic feedback to the areas around the mask. The smart mask and inhaler have a direct communication path to a smart device or it can be a smart device by itself; its various environmental and gas sensors act as a feedback mechanism. The detection level of the organic and non-organic VOC gas emitted when exhaling can be communicated and stored for analysis purposes. The detected gas can be regenerated on the same smart mask or a different remote smart mask.

An atomization device includes an atomization machine and an atomization bottle which can be disposed after use. The atomization bottle receives a liquid to be atomized to form a mist. The atomization bottle includes an atomization bottle cork to prevent leakage of the liquid. The atomization bottle cork includes an atomizer fee of power and any control module. A power supply and a control module are disposed on a machine body of the atomization machine. When the atomization bottle is coupled with the atomization machine, the atomizer can be activated by the control module to generate a mist. After the liquid in the atomization bottle is used up, the atomization bottle can be replaced by a new atomization bottle.

A wearable personal protection device for protecting a wearer against airborne pathogens comprises a battery-powered electronic circuit and components for controllable operation of at least one piezoelectric vibrating mesh transducer which is configured to intermittently simultaneously generate and shoot droplets of a biocide fluid into the wearer's proximal airspace to contact and inactivate at least some of the pathogens which may be present; a reservoir for containing the biocide fluid therein; and a fluid delivery apparatus for conveying said biocide fluid to an uptake location of the piezoelectric vibrating mesh transducer.

A method for controlling one or more scent delivery units includes maintaining one or more scheduled events, maintaining one or more scheduled anti-events, and generating, based on the one or more scheduled events and the one or more scheduled anti-events, command data to be communicated to the one or more scent delivery units to control their activation and deactivation. Generating the command data includes identifying a conflicting period of time during which control specified by the one or more scheduled events differs from control specified by the one or more scheduled anti-events and also includes generating command data that gives priority to control specified by the one or more scheduled anti-events. Control for the one or more scent delivery units during the conflicting period of time is in accordance with control logic of the one or more scheduled anti-events and not the one or more scheduled events.

The present application relates to an atmosphere adjusting method, an atmosphere adjusting device, and an aroma diffuser. The method comprising: receiving a recognition result of a smell for a specific position; obtaining a corresponding table that indicates a corresponding relationship between the recognition result of the smell and light and/or melody; determining the light and/or the melody to be output from the corresponding table, according to the recognition result of the smell; and instructing output of the corresponding light and/or melody. The technical solution of the application implements the adjustment of light and/or melody in response to the smell indoor, which makes the light and/melody change with the change of smell, thereby creating a harmonious and unified atmosphere in seeing, hearing and smelling for users.

A system having an enclosure for containing a solution. An atomizer is in communication with an interior of the enclosure and the solution for generating an aerosolized particle mist within the interior of the enclosure. A positive pressure device is in communication with the interior of the enclosure for generating a positive pressure within the enclosure relative to an atmosphere outside of the enclosure. An ejection nozzle having a tortuous path is provided, wherein an entrance of the tortuous path is in communication with the interior of the atomizer and an exit of the tortuous path is in communication with the atmosphere outside of the enclosure.

A system for inducing a Pavlovian conditioned association of an aroma with a state of satiation, the system comprising at least a physiological sensor, wherein the at least a physiological sensor is configured to detect at least a physiological parameter of a user, and to transmit a detection signal, a control device configured to receive the detection signal from the at least a physiological sensor, wherein the control device is further configured to ascertain that the user is experiencing a physiological state associated with satiation, and to transmit the detection signal to an automatically activated scent diffuser, thereby conditioning the user to associate said scent with satiation, and an automatically activated scent diffuser, wherein the scent diffuser is configured to automatically activate upon receiving the detection signal, wherein automatically activating further comprises diffusing a scent in response to the detection signal.

A microfluidic delivery device is provided. The microfluidic delivery device includes a housing electrically connectable with a power source. A cartridge is releasably connectable with the housing. The cartridge has a reservoir for containing a fluid composition and microfluidic die in fluid communication with the reservoir. The microfluidic die is configured to dispense substantially all of the fluid composition in an upward direction relative to horizontal. The microfluidic delivery device also includes a fan that is connected with the housing. The fan is configured to generate air flow that converges with and redirects the fluid composition dispensed from the microfluidic die in a first direction to a second direction that is different from the first direction.

A vacuum cleaner includes an odor neutralizer and dust plume abatement system. The odor neutralizer and dust plume abatement system delivers a mist to a working air path of the vacuum cleaner, such as at or upstream of a working air treatment assembly defining a portion of the working air path.
