Abstract
This aerosol supply device is provided with: an accommodating section (cartridge) that accommodates a liquid; an atomizing unit that atomizes the liquid to generate an aerosol; and an atomizing amount adjusting unit (gyro sensor and control unit) that adjusts the atomizing amount of the atomizing unit. The aerosol supply device is characterized in that the atomizing amount adjusting unit (gyro sensor and control unit) stabilizes the atomizing amount regardless of the inclination of the aerosol supply device within at least a certain range.
Core Innovation
An aerosol supply device includes an accommodating section that accommodates a liquid, an atomizer that atomizes the liquid to generate an aerosol, and an atomizing amount adjuster that adjusts an atomizing amount of the atomizer. The device further includes a built-in cartridge including at least the atomizer and a housing covering the built-in cartridge. The atomizing amount adjuster stabilizes an atomizing amount regardless of an inclination of the aerosol supply device within at least a certain range.
The atomizing amount adjuster includes an inclination maintaining portion that maintains an inclination of the built-in cartridge regardless of the inclination of the aerosol supply device within at least the certain range. In additional embodiments, the atomizing amount adjuster includes an inclination detection sensor and a control unit. The control unit adjusts at least one of electric power for atomization and the amount of liquid to be supplied to the atomizer based on a signal related to detected inclination.
Further configurations include an inclination maintaining portion and retaining portions that dispose the retaining portions horizontally even when the aerosol supply device is inclined. The configurations relate the retaining portions to a center-of-gravity of the built-in cartridge and to a built-in unit that keeps the retaining portions horizontal relative to housing inclination. Additional structure includes a discharge portion with a discharge port for discharging aerosol outward, where the direction of the discharge port intersects a direction normal to an extension surface of the retaining portion.
Claims Coverage
The patent includes one principal independent claim and related coverage with five inventive features. The claim coverage focuses on stabilizing atomizing amount under inclination, maintaining the built-in cartridge inclination, and further refinements for inclination detection and control, retaining portion horizontality, and discharge port orientation.
Inclination-stabilized atomizing amount with inclination maintaining portion
An atomizing amount adjuster stabilizes an atomizing amount regardless of an inclination of the aerosol supply device within at least a certain range, and includes an inclination maintaining portion that maintains an inclination of the built-in cartridge regardless of the inclination of the aerosol supply device within at least the certain range.
Inclination detection and power adjustment of atomization
An atomizing amount adjuster includes an inclination detection sensor and a control unit, and the control unit adjusts electric power for atomization based on a signal received from the inclination detection sensor indicative of the inclination of the aerosol supply device.
Inclination detection and liquid amount adjustment to the atomizer
An atomizing amount adjuster includes an inclination detection sensor and a control unit, and the control unit adjusts an amount of the liquid to be supplied to the atomizer based on a signal received from the inclination detection sensor indicative of the inclination of the aerosol supply device.
Horizontal retaining portion supported by cartridge center of gravity and vibratory element
An atomizer includes a retaining portion, a vibratory element, and a vibration source, where the built-in cartridge includes an inclination maintaining portion and has a center of gravity disposed below the retaining portion, and the inclination maintaining portion maintains an inclination of the built-in cartridge such that the retaining portion is horizontal.
Discharge port direction intersecting a normal to the retaining portion extension surface
A discharge portion includes a discharge port for discharging aerosol outside, and the atomizer includes a retaining portion such that a discharge port direction intersects a direction normal to an extension surface of the retaining portion.
Overall, the claim set focuses on stabilizing atomizing amount despite aerosol supply device inclination by maintaining the built-in cartridge inclination with an inclination maintaining portion, optionally using an inclination detection sensor and control unit to adjust either electric power for atomization or the liquid amount supplied to the atomizer, and further constraining atomizer retaining portion horizontality and discharge port orientation relative to a normal direction.
Stated Advantages
Stabilizes an atomizing amount regardless of an inclination of the aerosol supply device within at least a certain range.
