Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 illustrates a schematic diagram of the present invention.

DETAILED DESCRIPTION OF THE EMBODIMENT

(2) The present invention will be further described with the drawings and the embodiment.

(3) As figured in FIG. 1, a constant water level humidifier comprises an outer tank 1 with an outer outlet 10 disposed at the bottom; the outer outlet 10 is disposed with an oscillating plate 101, the upper portion of the outer tank 1 is disposed with an outer air vent 11 connected to the outer world; the outer tank 1 is further disposed with an inner tank 2; the lower portion of the inner tank 2 is connected to the outer tank 1 by a lock catch structure; the upper portion of the inner tank 2 is disposed with an inner air vent 21 connected to the outer air vent 11, the bottom portion of the inner tank 2 is disposed with an inner outlet 20 connected to the outer outlet 10 of the outer tank 1 and an inner inlet 22 connected to the chamber of the outer tank 1; the size of the inner outlet 20 is larger than that of the outer outlet 10. The inner inlet 22 is disposed with a water level control mechanism 23.

(4) The water level control mechanism 23 comprises a valve block 230 used to open and close the inner inlet 22 and a floating body 231 disposed in the inner tank 2, the floating body 231 is connected to the valve block 230 by a connecting rod 232. The inner outlet 20 further comprises a limit element 201 being disposed with a limit through hole 2010 sleeved on the connecting rod 232.

(5) When no water is in the inner tank 2, the floating body 231 of the water level control mechanism 23 falls down, driving the valve block 230 to open the inner inlet 22; at this time, water is filled to the outer tank 1, water in the outer tank 1 flows to the inner tank 2 through the inner inlet 22 and the water level in the water tank 2 raises, the floating body 231 floats up until it drives the valve block 230 to close the inner inlet 22, thereby the water level in the inner tank 2 keeps constant; when the oscillating plate 101 works, the water level in the inner tank 2 falls down, the floating body 231 drives the valve block 230 to fall down, again the inner tank 2 is connected to the outer tank 1, water in the inner tank 2 raises up to be constant.

(6) Although the present invention has been described with reference to the preferred embodiments thereof for carrying out the patent for invention, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the patent for invention which is intended to be defined by the appended claims.
