Further, since the cushioning member 60 is provided so that the slit 62 communicates with the through hole 35 formed in the partition wall 34, the through hole 35 is prevented from being completely closed by the cushioning member 60, and the battery It is possible to suppress an increase in pressure in the battery compartment for storing 21.
  • a suction device includes an aerosol generation unit, a control unit that controls the aerosol generation unit, a battery that supplies electric power to the aerosol generation unit and the control unit, an electrical equipment compartment for storing electrical equipment, and at least. It has a partition wall for partitioning the battery compartment for storing the battery, and a cushioning member arranged between the battery and the partition wall.
  • the cushioning member has a slit.
  • the partition wall has a through hole that communicates the electrical equipment compartment and the battery compartment. The through hole of the partition wall and the slit of the cushioning member communicate with air.
  • the electrolytic solution that has reached the slit of the buffer member is held in the slit by the surface tension of the electrolytic solution, so that the electrolytic solution can be suppressed from leaking from the through hole of the partition wall. Further, since the slit is provided so as to communicate with the through hole formed in the partition wall, the through hole is prevented from being completely closed by the cushioning member, and the pressure in the battery compartment for storing the battery is increased. It can be suppressed.
  • the gist of the second form is that, in the first form, the cushioning member is configured to be able to absorb a liquid.
  • the electrolytic solution can be held by the slit and the buffer member itself while suppressing the electrolytic solution from passing through the buffer member and leaking from the through hole.
  • the gist of the third form is that, in the first form or the second form, the cushioning member is configured to expand when it absorbs a liquid.
  • the slit closes due to the expansion of the cushioning member, or the width of the slit becomes smaller, which makes it difficult for the electrolytic solution to pass through the slit. As a result, leakage of the electrolytic solution from the through holes is further suppressed.
  • the gist of the fourth form is that, in any one of the first form to the third form, the slit has at least one curved portion.
  • the slit can be made longer than when the slit is linear, the amount of the electrolytic solution held by the slit is increased, and the electrolytic solution leaks from the through hole of the partition wall. It can be further suppressed.
  • the gist of the fifth form is that in any of the first to fourth forms, the slit includes an S-shaped portion.
  • the sixth form is any of the first to fourth forms, and the gist is that the slit includes a zigzag-shaped portion.
  • the seventh form is any of the first to sixth forms, and the gist is that the slit has a terminal portion.
  • the gist of the eighth form is that, in any one of the first to seventh forms, the cushioning member has a closed cell structure.
  • the electrolytic solution can be held by the slit and the buffer member itself while suppressing the electrolytic solution from passing through the buffer member and leaking from the through hole. Further, since the closed cell structure expands by absorbing the electrolytic solution, the slit closes or the width of the slit becomes smaller due to the expansion of the cushioning member, and the electrolytic solution becomes difficult to pass through the slit. As a result, leakage of the electrolytic solution from the through holes is further suppressed.
  • the gist of the ninth form is that the width of the slit is 0.7 mm or more and 1.5 mm or less in any of the first to eighth forms.
  • the electrolytic solution can be appropriately held by the slit.
  • the gist of the tenth form is that, in any one of the first to ninth forms, at least one end of the slit extends to the end face of the cushioning member.
  • the through hole formed in the partition wall and the battery compartment for storing the battery can be communicated with each other through the slit, the slit and the penetration when the pressure in the battery compartment rises. Pressure (gas) can be efficiently released to the electrical equipment compartment through the holes. As a result, the increase in pressure in the battery compartment can be further suppressed.
