Based on the foregoing, it can be seen that in the humidifier structure of the present embodiment, the evaporator 3 is disposed in the evaporation water tank 2 and between the fan 4 and the water tank 5.

In order to further save the space inside the outer casing 1, it has been mentioned above that the evaporation water tank 2 may be provided in the form of an annular groove, on the basis of which an upward protrusion may be provided in the middle of the evaporation water tank 2, the inside of the protrusion forming a cavity, so that the motor 13 may be installed in the cavity, thereby effectively utilizing the space between the cylindrical evaporator 3 and the evaporation water tank 2.

Preferably, the water storage tank 6, the evaporator 3, the evaporation water tank 2 and the fan 4 may be installed in the outer casing 1 in a longitudinal manner in sequence as shown in fig. 2, and the central axes of the water storage tank 6, the evaporator 3, the evaporation water tank 2 and the fan 4 coincide with each other, so as to further control the overall volume of the humidifier, thereby really realizing an ultra-small volume and being equipped with a large-capacity water storage tank, so that the structure of the humidifier is more compact.

In the embodiment, the fan 4 is arranged at the lower part of the evaporator 3, and the air inlet 5 is additionally arranged at the lower part of the outer shell 1, so that the noise generated by the motor 13 of the fan 4 in the running process can be blocked and absorbed by the evaporator 3, thereby effectively reducing the noise of the running humidifier, and the noise is lower than 25dB when the humidification amount is 200ml/h through the test of a prototype in a laboratory of an applicant, so that the humidification amount per unit time can be increased by increasing the rotating speed of the fan; and through designing the air current passageway 11 between storage water tank 6 outer wall and shell body 1 to the lower part with evaporimeter 3 surrounding storage water tank 6, thereby form longitudinal air current passageway 11, in order to reduce the air current of air current passageway 11 and cause the hindrance, also can further reduce the volume of humidifier, make the structure of humidifier compacter, also can promote the holistic aesthetic property of humidifier combining underlying air intake 5.

Still referring to fig. 2, in a more preferred embodiment of the present invention for solving the technical problems, in order to optimize the structure of the air flow passage 11 and to make sufficient space for the evaporator 3, the water storage tank 6 may be directly designed to have a T-shaped longitudinal section, as shown in fig. 2, the upper portion of the water storage tank 6 is larger than the lower portion of the water storage tank 6, so that the evaporator 3 may be installed around the lower portion of the water storage tank, as shown in the drawing, the evaporator 3 may also be designed to have a T-shaped cylindrical structure, when the cylindrical evaporator 3 is installed around the lower portion of the water storage tank 6, the evaporator 3 is engaged with the lower portion of the water storage tank 6, and the lower portion of the evaporator 3 is submerged into the evaporation water tank 2.

The water in the evaporation water tank 2 can be favorably immersed into the evaporator 3 from bottom to top smoothly, and most impurities in the water are filtered by the part with high folding density at the lower part of the evaporator 3 in the process that the water in the evaporation water tank enters the evaporator 3 from bottom to top through the capillary phenomenon, so that the cleanliness of the water entering the upper part of the evaporator 3 is improved, and the impurities in the water are prevented from entering the air along with the evaporation of air flow; and through the structure that the evaporator 3 is sparse from top to bottom, the airflow channel 11 is fully distributed at the upper part of the evaporator 3, so that the airflow must pass through the evaporator 3, the moisture on the evaporator 3 is evaporated, and the humid evaporator 3 adsorbs and cleans the air passing through the airflow channel 11, namely, the evaporator 3 can adsorb small particles in the air. Based on aforementioned same thinking, still can install a primary filter screen on the air intake 5 of shell 1, but through the big particulate matter in this primary filter screen filtered air to cooperate with aforementioned 3 adsorption of evaporimeter.
