The printed circuit board may be arranged in the wall of the humidifier chamber 16, and may be provided with a light such as an LED to illuminate the inside of the water tank 20 to visually check the water level. With reference to FIG. 4, an opening 35 may be provided in the outer wall of the humidifier chamber 16 so that light on the printed circuit board illuminates the humidifier chamber 16. The opening 35 is covered with a cover 37 to prevent access to the printed circuit board as well as the light source (eg, LED) from the humidifier chamber 16. The cover 37 can be transparent or colored so that colored light, such as green, appears in the humidifier chamber 16. Light is provided to illuminate the interior of the humidifier chamber 16 and allows visualization of the water level in the water tank 20. Instead, multiple light sources are placed on the printed circuit board to provide various indications regarding the heating of the water tank, for example, a darkroom light is provided to indicate that the humidifier is heating to a specified temperature and a blue light. It may be identified that the provided humidifier is at a specified temperature.
0032The humidifier 14 includes a humidifier chamber 16 and a lid 18 pivotally connected to the humidifier chamber 16. As shown in FIGS. 3 to 4, the lid 18 is provided with a hinge portion 17, and the hinge portion 17 is hinged to the hinge portion 47 provided in the humidifier chamber 16. With reference to FIG. 3, a chamber bottom plate 54 is provided in the humidifier chamber 16, details of which are shown in FIG. An opening member 28 is provided to release the lid 18 and pivots the lid to the open position, as described in detail below.
0033Referencing FIG. 3 and FIG. 4 again, the lid 18 comprises a clasp 15, which is configured to engage the latch 44 to keep the lid in the closed position. Also, the seal 19 has a wedge-shaped protrusion 13, which engages the water tank 20, for example, the water tank lid 86, and directs the water tank 20 toward the outlet 34 of the humidifier chamber 16 when the lid 18 is in the closed position. Press to help form a seal between the aquarium outlet 88 and the humidifier chamber outlet 34. Further, the dome portion 11 is provided on the seal 19, and the water tank 20 is pressed toward the heating plate 36 when the lid 18 is in the closed position. Further, a circular seal portion or a seal ring 21 is provided on the seal 19, and when the lid 18 is in the closed position, the discharge port 89 of the water tank provided in the water tank lid 86 is sealed.
0034Referring again to FIGS. 2 and 4, the humidifier chamber 16 also includes an air inlet 22, which is the flow generator 12 when the humidifier 14 is connected to the flow generator 12 by a latch 24.
