If the pressure in the water tank becomes abnormally high due to clogging of the nozzle, the safety valve operates and the water pressure in the water tank drops. However, when the internal pressure falls below the set pressure (below the spring biasing force of the safety valve), the safety valve is reactivated. Operates, and the middle cap closes the upper opening of the water supply tank. In this state, high-pressure steam still remains in the water supply tank. Therefore, if the cap is accidentally removed at the stage where the pressure becomes lower than the set pressure and the water supply tank is closed again after the safety valve is operating or after the safety valve is operated, the remaining steam is blown out at once. In other words, since the outer peripheral portion of the cap body is a complete space, at the moment when the engagement piece is disengaged from the engagement receiving piece, the residual steam is blown out from the lower peripheral portion of the cap body at once, causing the user to be burned. There is a danger of doing so. In addition, since it is unknown whether the pressure relief valve is operating or not, if the pressure relief valve is activated and the power switch is turned off, the temperature of the water supply tank decreases,
The pressure in the tank drops below the pressure in the cap. That is, as a result of the negative pressure, there is a disadvantage that it is difficult to remove the cap body (middle cap).

In the inhaler having such a configuration, the pressure relief valve includes a curved spring plate and a reset spring shaft that also serves as a notification during operation. The outer peripheral edge of the disk-shaped curved spring plate is fixed,
The central portion is curved downward (toward the steam passage portion), and the central portion closes the steam passage portion. In addition, the reset spring shaft for both operation and notification is directed downward (in the direction of the curved spring plate) with its base end fitted into a hole provided in the bottom wall of the cap body.
Has been energized. The spring force of the curved spring plate is set to be larger than the urging force of the reset spring shaft. Under normal conditions,
That is, in a state where the cap body is fitted to the water supply tank, the center of the curved spring plate closes the steam passage portion, the distal end of the reset spring shaft presses the center of the curved spring plate, and the base end is substantially the cap. It is set to be flush with the outer surface of the bottom wall of the body.

For example, when the nozzle is clogged and the internal pressure in the water supply tank becomes abnormally high (when it becomes higher than the urging force of the curved spring plate), the curved spring plate is inverted by the high pressure. That is, the center of the curved spring plate rises toward the bottom wall of the cap body, and the curved direction is reversed. At this time, the reset spring shaft also rises against the spring urging force by the curved spring plate, and the steam passage portion is opened. At the same time, the base end of the reset spring shaft rises and projects outward from the bottom wall of the cap body. Thereby, it can be seen that the safety valve is in operation, and the high pressure in the water supply tank escapes from the space between the cap body and the water supply tank when the steam passage is opened. Even if the internal pressure of the water supply tank decreases and becomes equal to or lower than the set pressure, the inverted curved spring plate does not return to the original shape. Therefore, the reset spring shaft cannot be returned, the steam passage portion remains open, and the internal pressure of the water supply tank drops completely to atmospheric pressure. That is,
When the user pushes down the base end of the reset spring shaft protruding above the bottom wall of the cap body, the center portion of the curved spring plate returns to the original shape for the first time, and the reset spring shaft also returns to the original shape. Therefore, even if the cap body is removed from the water supply tank, there is no danger of injecting steam and burning, etc., and the internal pressure of the water supply tank does not become negative pressure compared to the internal pressure of the cap body, Disadvantages such as difficulty in removing the cap are eliminated.

In the inhaler having such a configuration, when the cap body is fitted to the water supply tank, the outer peripheral surface of the cap body is substantially in contact with and surrounded by the inner surface of the cylindrical steam injection preventing wall. Therefore, if the cap body is mistakenly removed immediately after the safety valve is operated or after the safety valve is operated and the safety valve is restored, the steam remaining in the water supply tank will pass through the steam passage portion between the cap body and the steam injection preventing wall. Attempts to escape outward from the gap. Here, the outer peripheral surface of the cap body is almost in contact with the steam injection preventing wall, and only a small gap is formed between the two, so that the steam escapes from the gap to the outside. Therefore, when the cap body is about to be removed, a large amount of high-temperature steam does not erupt to the outside at one time, and disadvantages such as burns of the user are eliminated.
