The pressing portion 5 is formed in a disk shape, and is easily positioned with respect to the adsorption member 4 by inserting it into the housing recess 42 .

The suction cup fixing member 5 is formed with six protrusions 51 extending upward at regular intervals along the circumferential direction. The projecting portion 51 is formed at a position corresponding to the holes 43 and 36 and can be inserted into these holes 36 and 43 . FIG. 5 shows the inserted state. In this state, by crushing the tip 51a of the projecting portion 51 by ultrasonic welding or the like, it becomes impossible to escape from the holes 36 and 43, and the suction cup fixing member 5 falls off the base portion 3. become unable to. As a result, the adsorption member 4 can be firmly fixed to the pedestal portion 3 .

A cylindrical portion 52 that protrudes in the same direction as the protruding portion 51 is formed in the center of the suction cup fixing member 5 . The tubular portion 52 is fitted into the fitting hole 48 formed in the center of the suction cup member 4 .

<Usage condition>
When the humidifier according to the present embodiment is installed on the floor, it is sufficient to simply place the humidifier on the floor, and the operation for causing the adsorption member 4 to act is unnecessary. FIG. 5B shows a state in which the humidifier is actually installed on the floor, but the dome portion 41 of the adsorption member 4 is compressed, and the dome portion 41 is divided into the first dome housing portion 30 and the second dome housing portion 31. The humidifier is installed in a stable state. Further, the third surface 24 of the lower main body 2 and the contact portion 44 of the suction member 4 are in contact with each other, so that the weight of the device main body A is easily transmitted to the suction member 4, and the suction member 4 is reliably operated. be able to.

Further, when moving the humidifier, the suction state with the floor surface can be released by lifting the humidifier from the floor surface.
