- the power supply unit 111 is provided so as to be detachable from the case 20 of the inhalation device 100.
- An example of a mode of attachment and detachment of the power supply unit 111 will be specifically described below.
- the direction in which the flavor source 131 or the stick-type substrate 150 is inserted into and removed from the inhalation device 100 is defined as the up-down direction
- the side of the inhalation device 100 into which the flavor source 131 or the stick-type substrate 150 is inserted is defined as the upper side. That is, the flavor source 131 or the stick-type substrate 150 is inserted into the inhalation device 100 from above.
- a direction perpendicular to the up-down direction may be referred to as the lateral direction
- a surface facing the lateral direction may be referred to as a side surface.
- the power supply unit 111 may be provided so as to be detachable from the suction device 100 in a manner other than the first to fourth examples described below.
- FIG. 4 is a diagram showing a first example of a manner in which the power supply unit 111 can be attached and detached.

Therefore, in the insertion direction of the power supply unit 111 inserted from the opening 24, the power supply accommodating section 200 and the board accommodating section 210 are provided in this order from the opening 24.
- the board housing section 210 houses the main body side board unit 90, which is configured to include ICs and the like that make up the control section 116.
- the main body side board unit 90 is electrically connected to the power supply section 111 housed in the power supply housing section 200, for example, via a flexible cable 250 or the like. This makes it possible to supply power from the power supply section 111 housed in the power supply housing section 200 to the main body side board unit 90.
- the case 20 is provided with a connection section 26 that is connected to the terminal 1119 of the power supply section 111 housed in the power supply housing section 200.
- the connection section 26 is electrically connected to the main body side board unit 90 via, for example, a flexible cable 250.
- the power supply unit 111 has multiple terminals 1119, and the case 20 has connection parts 26 corresponding to each of the terminals 1119. Also, in the example shown in FIG. 4, all of the terminals 1119 of the power supply unit 111 are provided on the upper surface of the power supply unit 111, and therefore all of the connection parts 26 of the case 20 are also provided on the upper wall part 22 of the power supply accommodating part 200.
- the multiple terminals 1119 provided on the power supply unit 111 can include, for example, a first output terminal 1119a and a second output terminal 1119b, which will be described later.
- the upper wall portion 22 is a partition portion disposed between the power supply accommodating portion 200 and the board accommodating portion 210 in the insertion direction of the power supply unit 111. Because the upper wall portion 22 is disposed between the power supply accommodating portion 200 and the board accommodating portion 210 in the insertion direction of the power supply unit 111, the power supply unit 111 is prevented from entering the board accommodating portion 210 and coming into contact with elements disposed on the main body side board unit 90.
- the upper wall portion 22 functions as a restricting portion 29 that restricts the power supply portion 111 from entering the board accommodation portion 210.
- the restricting portion 29 it is preferable for the restricting portion 29 to cover at least the electrical connection portion between the main body side board unit 90 and the elements arranged on the main body side board unit 90 as viewed from the power supply accommodation portion 200, it is more preferable for the restricting portion 29 to cover the elements arranged on the main body side board unit 90, and it is even more preferable for the restricting portion 29 to cover the entire main body side board unit 90.
- a communication section 25 that communicates between the power supply accommodating section 200 and the board accommodating section 210 is formed in the upper wall section 22, and a flexible cable 250 is inserted into the communication section 25.
- the upper wall section 22 may be provided with a communication section 25 that communicates between the power supply accommodating section 200 and the board accommodating section 210, but the area of the communication section 25 perpendicular to the insertion direction of the power supply section 111 is smaller than the area of the power supply section 111 perpendicular to the insertion direction of the power supply section 111. This prevents the power supply section 111 from entering the board accommodating section 210 through the communication section 25 and coming into contact with elements arranged on the main body side board unit 90.
- the main body side board unit 90 has a first surface 90a on which a plurality of elements and electrical connection parts of the flexible cable 250 are mounted, and the first surface 90a is arranged in a direction perpendicular to the insertion direction of the power supply unit 111. Furthermore, by arranging the board at a position that does not overlap with the position of the communication part 25 when viewed from the insertion direction of the power supply unit 111, the mounting part of the element mounted on the board (i.e., the electrical connection part) is arranged so as not to be exposed to the power supply accommodating part 200.
- the restricting part 29 is arranged between the power supply accommodating part 200 and the mounting part of the element.
- the mounting part of the control element for example, the MCU 1161 described later
- the power supply unit 111 is prevented from coming into contact with the control element that controls the supply of power to the heating part 121, thereby improving safety.
- the power supply housing 200 communicates with the outside of the case 20, making it possible to remove the power supply unit 111 from the power supply housing 200.
- FIG. 5 is a diagram showing a second example of the attachment/detachment mode of the power supply unit 111. Note that, here, the description will be centered on the parts that are different from the description of Fig. 4, and the description of the parts that are common to the description of Fig. 4 will be omitted or simplified as appropriate.
- the power supply housing 200 communicates with the outside of the case 20, and it becomes possible to insert the power supply unit 111 into the power supply housing 200 from the side of the case 20.
- an opening 24 is provided on the side of the case 20, and the opening 24 is configured to be openable and closable by the panel 30.
- the board accommodating section 210 is not positioned in the insertion direction of the power supply section 111 inserted through the opening 24.
- the terminals 1119 of the power supply unit 111 are provided on each of the top, bottom, and side surfaces of the power supply unit 111. Therefore, the connection parts 26 of the case 20 are also provided on each of the top wall part 22, bottom wall part 21, and side wall part 23. Note that the terminals 1119 of the power supply unit 111 may be concentrated in one location on the power supply unit 111 as shown in FIG. 4, and correspondingly, the connection parts 26 of the case 20 may also be concentrated in one location on the case 20.
- the power supply unit 111 Since the board accommodating section 210 is not positioned in the insertion direction of the power supply unit 111 inserted from the opening 24, the power supply unit 111 does not normally enter the board accommodating section 210. However, if the power supply unit 111 is inserted at an angle from the opening 24, a part of the power supply unit 111 may enter the board accommodating section 210. However, the upper wall section 22, which is arranged between the power supply accommodating section 200 and the board accommodating section 210 as viewed from the power supply accommodating section 200, prevents the power supply unit 111 from coming into contact with the electrical connection section of the element arranged on the main body side board unit 90 with the main body side board unit 90. In this example, the upper wall section 22 functions as a restricting section 29 that restricts the power supply unit 111 from entering the board accommodating section 210.
- the power supply housing 200 communicates with the outside of the case 20, making it possible to remove the power supply unit 111 from the power supply housing 200.

Therefore, the connection parts 26 of the case 20 are also provided on each of the top wall part 22, bottom wall part 21, and partition part 27. Note that the terminals 1119 of the power supply unit 111 may be concentrated in one place on the power supply unit 111 as shown in FIG. 4, and correspondingly, the connection parts 26 of the case 20 may also be concentrated in one place on the case 20.
- the partition wall 27 may be provided integrally with the case 20, or may be provided separately from the case 20 and attached to the case 20, but is arranged in a fixed state to the case 20 when the power supply unit 111 is replaced. When the power supply unit 111 is replaced, the power supply unit 111 is prevented from entering the board housing portion 210 and coming into contact with elements arranged on the main body side board unit 90.
- the partition wall 27 functions as a restricting portion 29 that restricts the power supply unit 111 from entering the board housing portion 210.
- the partition 27 is penetrated by a flexible cable 250 extending from the connection portion 26 and connected to the main body side board unit 90, and a communication portion 25 is formed to communicate between the power supply accommodating portion 200 and the board accommodating portion 210.
- the partition 27 may be provided with communication portions 25 such as through holes, gaps, notches, etc. other than the through holes through which the flexible cable 250 passes, but the area of the communication portion 25 perpendicular to the insertion direction of the power supply unit 111 is smaller than the area of the power supply unit 111 perpendicular to the insertion direction of the power supply unit 111. This prevents the power supply unit 111 from entering the board accommodating portion 210 through the communication portion 25 and coming into contact with elements arranged on the main body side board unit 90.
- the partition wall 27 preferably covers at least the electrical connection between the elements arranged on the first surface 90a of the main body side board unit 90 as viewed from the opening 24, more preferably covers the elements arranged on the main body side board unit 90, and even more preferably covers the entire main body side board unit 90.
