That is, either one of the pair of main surface portions 12A may be provided with a through hole for forming the first air inlet 18A. Even in this case, it is possible to prevent both the first air inlet 18A and the second air inlet 18B from being blocked.

According to this configuration, the second air inlet 18B is formed in the gap between the exposed inner case 20 and the outer case 13 at the corner portion 12C of the housing portion 12, and is formed in a portion other than the corner portion 12C of the housing portion 12. Since the shape is completely different from that of the first air inlet 18A, it is difficult to block both the first air inlet 18A and the second air inlet 18B.
  • the edge of the exposed portion 13b is curved. According to this configuration, since the edge of the exposed portion 13b is not straight but curved, it is difficult for the second air inlet 18B to be completely blocked even if the user's finger touches it.
  • the housing part 12 has a projecting part 90 around the second air inlet 18B. According to this configuration, even if the user's finger touches the periphery of the second air inlet 18B, the projecting portion around the exposed portion 13b forms a step and forms a gap between the exposed portion 13b and the user's finger. The air inlet 18B is less likely to be blocked.
  • the housing part 12 has a protruding part 90 around the second air inlet 18B, and the protruding part 90 is formed by the outer case 13 . According to this configuration, since the projecting portion 90 around the exposed portion 13b is formed integrally with the outer case 13, the projecting portion 90 can be easily formed.
  • the housing part 12 includes a communication hole 17a communicating with the cartridge housing space 10A, a first air flow path 70 communicating the first air inlet 18A and the communication hole 17a, and a second air flow path 70. and a second air flow path 80 that communicates between the inlet 18B and the communication hole 17a.

  • the communication hole 17a has a channel cross-sectional area smaller than that of both the first air inlet 18A and the second air inlet 18B. According to this configuration, even if one of the first air inlet 18A and the second air inlet 18B is blocked, the cross-sectional area of the passage is finally narrowed in the communication hole 17a, so that the air is sucked into the cartridge housing space 10A. The flow rate and flow velocity of the air drawn can be kept substantially constant.
