Abstract

The present invention provides a power unit and method for an aerosol generating device capable of appropriately determining the occurrence of an abnormality that necessitates the substantial prohibition of the use of the device. The power unit comprises a control means for controlling the temperature of a load that heats an aerosol source, and a first maintenance means for maintaining first information indicating whether an abnormality regarding the load has been detected by means different from the control means. The control means determines that an abnormality has occurred that necessitates the prohibition of the use of the power unit if, during the period from the start of temperature control of the load until its termination, it detects that the first information has changed to a state indicating that an abnormality has been detected.

Description

Power unit and method of an aerosol generating device The present invention relates to a power unit of an aerosol generating device and a method of operating the power unit of an aerosol generating device. An aerosol generating device, such as an electronic cigarette, has a configuration for heating a liquid to form an aerosol. Patent Document 1 discloses an aerosol generating device in which, when a controller detects overheating of a heater, the controller limits or turns off the power supply from the battery to the heater. [Fig. 1] A drawing showing an example of the appearance of a power unit of an aerosol generating device related to an embodiment. [Fig. 2] A perspective view showing an example of the internal configuration of a power unit related to an embodiment. [Fig. 3] A drawing showing an example of the overall circuit configuration of a power unit related to an embodiment. [Fig. 4] A diagram showing an example of a temperature control pattern. [Fig. 5] A drawing taken from a portion of Fig. 3. [Fig. 6] A drawing showing an example of a battery abnormal condition in a power unit related to an embodiment. [Fig. 7] Flowchart relating to the temperature control operation of a power unit related to an embodiment. [Fig. 8] Flowchart regarding processing during startup of a power unit related to an embodiment. Hereinafter, embodiments will be described in detail with reference to the attached drawings. Furthermore, the following embodiments are not intended to limit the invention related to the patent claims, nor can it be said that all combinations of features described in the embodiments are essential to the invention. Two or more of the multiple features described in the embodiments may be arbitrarily combined. Additionally, the same reference number is assigned to identical or identical components, and redundant descriptions are omitted. FIG. 1 is an external perspective view schematically showing an example of the configuration of a power unit (1) of an aerosol generating device related to one embodiment of the present invention. The power unit (1) has a case (2) in the shape of a roughly rectangular body with rounded corners. The case (2) forms the surface of the power unit (1). Here, for convenience, the surface indicated by a in FIG. 1 is designated as the front surface, and the surface indicated by b is designated as the back surface. Additionally, the surface indicated by c in FIG. 1 is designated as the bottom surface, and the surface indicated by d is designated as the ceiling surface. The power unit (1) has a housing (case) (2) and a front panel (11) that is detachable from the case (2). Fig. 1f shows the state in which the front panel (11) is detached from state a. Also, Fig. 1g shows the state in which the front panel (11) is viewed from the inside. The front panel (11) functions as a front cover of the case (2) and allows the user to freely exchange it to customize the appearance. On the inner surface of the front panel (11) and on the front surface of the case (2), two pairs of magnets (14A and 14B) and magnets (15A and 15B) are formed in opposing positions. As magnets (14A) and (15A) attract each other and magnets (14B) and (15B) attract each other, the front panel (11) is held to the front surface of the case (2) by magnetic force. Additionally, a pushable switch (SW) and a light-emitting part (NU) are formed on the front of the case (2). On the inner surface of the front panel (11), a convex part (16) is formed at a position opposite to the switch (SW). When the front panel (11) is mounted, the switch (SW) can be indirectly pressed through the convex part (16) by pressing the area near the center (12) of the front panel (11). Additionally, the switch (SW) can be pressed directly when the front panel (11) is detached. A plurality of light-emitting elements (e.g., LEDs) are arranged in a row in the light-emitting part (NU). The state of the light-emitting part (NU) can be observed through a window (19) formed in the front panel (11). A slider (13) that can be opened and closed is formed on the ceiling surface of the case (2). When the slider (13) is moved in the direction of the arrow, a heater chamber (17) appears as shown in e of FIG. 1. For convenience, the slider (13) is not shown in e. The heater chamber (17) is a cylindrical space having an elliptical (long rectangular) horizontal cross section and heats a stick or cartridge inserted into the heater chamber (17). The stick is cylindrical in shape, and the diameter of the horizontal cross section is made larger than the short diameter of the horizontal cross section of the heater chamber (17). As a result, when the stick is inserted into the heater chamber (17), the contact between the outer surface of the stick and the heater chamber (17) is increased, and the contact area is increased. Therefore, the stick can be heated efficiently. This allows for an improvement in the amount of aerosol generated from the stick and the flavor.
