The first partition plate 12 is positioned at the top of the water tank 11, and the first partition plate 12 is used for sealing the outer edge of the water tank 11 and separating the water tank 11 from the water leakage prevention structure 3; the input end of the water leakage prevention structure 3 is communicated with the water tank 11, the output end of the water leakage prevention structure 3 is respectively communicated with the second air outlet 142 and the third air outlet 143, and the water leakage prevention structure 3 can prevent water flow from flowing out of the second air outlet 142 or the third air outlet 143. When the humidifier body 1 is placed vertically, the steam is discharged outwards from the second air outlet 142 and the third air outlet 143; when the humidifier body 1 is horizontally placed, the steam is discharged from the second outlet 142 or the third outlet 143.

According to the dumping pressure relief structure for the liquid heating device, the first partition plate 12 can seal the outer side edge of the water tank 11, and water flow is reduced and flows out of the humidifier body 1 from the outer side edge of the water tank 11.
