Abstract

An aerosol generation device having a vibration part and a control method thereof are provided. The aerosol generation device according to some embodiments of the present disclosure may include a housing including an accommodation space for accommodating an aerosol-generating article, a heating element configured to be inserted into the aerosol-generating article accommodated in the accommodation space and heat the accommodated aerosol-generating article to generate an aerosol, and a vibration part. The vibration part may vibrate the heating element to prevent formation of stuck-on residue on the heating element and allow removal of stuck-on residue formed on the heating element.

First claim

What is claimed is:

1 . An aerosol generation device comprising:
a housing including an accommodation space for accommodating an aerosol-generating article; a heating element configured to be inserted into the aerosol-generating article accommodated in the accommodation space and heat the accommodated aerosol-generating article to generate an aerosol; a vibration part configured to vibrate the heating element in a vertical direction of the accommodated aerosol-generating article; and a controller configured to control the vibration part, wherein the controller is configured to operate the vibration part to vibrate in the vertical direction while the heating element is being inserted into the aerosol-generating article.

2 . The aerosol generation device of claim 1 , wherein the vibration part vibrates the heating element in a horizontal direction of the accommodated aerosol-generating article or vibrates the heating element in a twist form.

3 . The aerosol generation device of claim 1 , wherein the controller operates the vibration part at a time point at which smoking ends or while the accommodated aerosol-generating article is being removed.

4 . The aerosol generation device of claim 1 , wherein the controller operates the vibration part at a time point at which preheating occurs.

5 . The aerosol generation device of claim 1 , wherein the controller controls an operation of the vibration part based on a predetermined time condition.

6 . The aerosol generation device of claim 1 , wherein the controller operates the vibration part in response to a determination that a temperature of the heating element is a reference value or higher.

7 . The aerosol generation device of claim 1 , wherein the controller controls a vibration intensity, a vibration duration, or a vibration speed of the vibration part based on a temperature condition of the heating element.

8 . The aerosol generation device of claim 1 , wherein the controller operates the vibration part in response to detection of a user's puff.

9 . The aerosol generation device of claim 1 , wherein the controller controls a vibration intensity, a vibration duration, or a vibration speed of the vibration part based on a user's puff condition.

10 . The aerosol generation device of claim 1 , wherein the vibration part includes an ultrasonic vibrator that converts an electric signal into the vibration that vibrates the heating element, and
wherein the electric signal applied to the vibration part is in a range from 20 KHz to 40 KHz.
