[0004] However, these prior art techniques are unable to specifically determine in which part of the aerosol generating device starvation of the aerosol source is occurring
Therefore, there is still room for improvement regarding the structure, operation method, etc. of the aerosol generating device for performing appropriate control when the aerosol source is insufficient.

[0136] figure 2 It is a figure which shows the exemplary circuit structure concerning a part of 100 A of aerosol generating apparatuses based on 1st Embodiment of this disclosure.
[0137] figure 2 The illustrated circuit 200 includes a power supply 110, a control section 106, an element 112, a load 132 (also referred to as a "heater resistor"), a first path 202, a second path 204, a circuit comprising a first field effect transistor (FET) 206 A switch Q1 , a constant voltage output circuit 208 , a switch Q2 including a second FET 210 , and a resistor 212 (also referred to as “shunt resistance”). Those skilled in the art should understand that not only FETs can be used as the switches Q1 and Q2 , but various devices such as iGBTs and contacts can also be used as the switches Q1 and Q2 .
[0138] Figure 1A The circuit 134 shown electrically connects the power source 110 to the load 132 and may include a first path 202 and a second path 204 . The first path 202 and the sec...

[0236] With regard to the aerosol generating device 100 according to the embodiment of the present disclosure, at an interval shorter than that of normal suction (for example, shorter than the time required to supply a sufficient amount of aerosol from the storage part 116 to the holding part 130 When suctioning is performed at an interval), a temporary shortage of the aerosol source in the holding unit 130 may occur even if a sufficient amount of the aerosol source is stored in the storage unit 116 . The same problem may occur also when the suction capacity in one suction is larger than that in normal suction. The same problem may occur when the suction time in one suction is longer than that of normal suction. These are but a few examples of attractions where the above mentioned problems can occur. It is hoped that those skilled in the art will understand that unintended attraction modes with a wide variety of characteristics may cause the same problem to occur. The second...

[0275] As described in the first embodiment of the present disclosure, it is possible to realize an aerosol generating device capable of distinguishing whether it is in the first state or the second state, wherein the first state is that the aerosol source stored in the storage part is insufficient. The second state is a state in which the storage part can supply the aerosol source but the aerosol source held by the holding part is insufficient. The third embodiment of the present disclosure described below can appropriately control the aerosol generating device having such characteristics.
[0276] The structure of the aerosol generating device described in relation to the first embodiment of the present disclosure (for example, with Figure 1A , Figure 1B , figure 2 , image 3 , Figure 8 etc. are described in relation to the structure) and action methods (for example, with Figure 6 , Figure 7 , Figure 10 , Figure 12B , Figure 13B etc.), and the operation meth...

Abstract
The present invention provides an aerosol generating device which is capable of performing appropriate control at a time when there is a shortage of aerosol sources. This aerosol generating device 100A is provided with: a power supply 110; a load 132 which generates heat upon receipt of electric power fed from the power supply 110 so as to atomize an aerosol source; a component 112 which is used to acquire a value related to the temperature of the load 132; a circuit 134 which electrically connects the power supply 110 and the load 132; a storage part 116 in which the aerosol source is stored;a retention part which retains the aerosol source supplied from the storage part 116 in such a state as to be ready for heating by the load 132; and a control unit 106 which is configured to discriminate, on the basis of a change of the value related to the temperature of the load 132 after the circuit 134 has come to function, whether the aerosol generating device 100 is in a first state in which there is a shortfall in the aerosol source stored in the storage part 116 or in a second state in which there is a shortfall in the aerosol source retained in the retention part 130 even though thestorage part 116 is able to supply the aerosol source.
Description
technical field [0001] The present disclosure relates to an aerosol generating device that generates an aerosol to be inhaled by a user, and a method and program for operating the same. Background technique [0002] In general electronic cigarettes, heated cigarettes, or nebulizers, etc., which are used to generate the aerosol that the user wants to inhale, if the aerosol source that becomes an aerosol due to atomization is insufficient, the user If suction is performed, sufficient aerosol cannot be supplied to the user. Not only that, but in the case of electronic cigarettes or heated cigarettes, there occurs a problem that an aerosol having an undesired savory taste may be released. [0003] As a solution to this problem, Patent Document 1 discloses a technique for detecting depletion of an aerosol source based on a change in heater temperature when electric power is supplied to a heater for heating an aerosol source. Other Patent Documents 2 to 11 also disclose various ...
