を入れると定常状態で液が噴霧される。Embodiment FIG. 1 and FIG. 2 show the structure of the whole inhaler. Reference numeral 1 denotes a housing of the inhaler main body, which is formed of a synthetic resin. A switch lever 2, a bottom cover 3, a water supply tank 4, a mask 5, and the like are attached to the housing 1. In the case of the present embodiment, the inhaler is a nebulizer that atomizes and sprays a liquid using ultrasonic vibration energy, and includes an ultrasonic vibration horn 6, a drive circuit 10, and a power supply 8. The ultrasonic vibration horn 6, the drive circuit 10, and the power supply 8 are electrically connected, and the switch 9 provided on the drive circuit 10 is turned on and off by opening and closing the switch 9 with the switch lever 2. Reference numeral 7 denotes a water absorbing member as an example of a water absorbing member, which is formed of felt or the like. The spray liquid is guided to the vibration surface 13 of the ultrasonic vibration horn 6 by the water absorbing body 7. The water supply tank 4 is removably attached by fitting, and the water supply tank 4 has an opening 11.
The water-absorbing body 7 is inserted with an appropriate gap. The water supply tank 4 is formed in a substantially horseshoe shape, and an opening 11 is formed in the center of the water supply tank 4. As shown in FIG. 3, the water supply tank 4 has a lower space a, an upper space b, a front space c, a rear space d, a left space e, and a right space f around the opening 11 as shown in FIG. However, the volumes of these spaces a, b, c, d, e, and f are equal. The water supply tank 4 is filled with a half of the total volume of the water supply tank 4 and is used by being attached to the inhaler main body. No liquid leaks from the part 11. For example, when the switch lever 2 of the inhaler is directed upward as shown in FIG. 4 (a), the water supply tank 4 as shown in FIG.
The liquid does not collect and spill in the space a at the lower part of the inhaler, and as shown in FIG.
4B, the liquid does not collect in the space f on the right side of the water supply tank 4 as shown in FIG. 4B ', and does not spill out, and as shown in FIG. In a state where 2 is directed downward, the liquid does not collect in the upper space b as shown in FIG. 4C 'and does not spill out, and the mask 5 is directed downward as shown in FIG. 4D. 4th in state
As shown in FIG. 5D ', the liquid does not collect in the front space c and spills. Therefore, the liquid does not spill out of the water supply tank 4 even when directed toward the inhaler or the like. FIG. 4 (a) 'shows a normal use state, in which the water absorbing body 7 is immersed in the liquid in the water supply tank 4, and the switch 9
, The liquid is sprayed in a steady state.

Since the shape of the water supply tank is formed so that the volume of each of the upper space and the lower space is equal, the spray in the water tank can be formed regardless of the direction of the inhaler. The liquid surface of the liquid is not located above the opening,
Liquid can be prevented from leaking from the opening without leaking, and since the opening is open to the atmosphere, the inside of the water supply tank can be kept at atmospheric pressure and spraying can be stabilized. You can do it.
