In order to ensure the compactness of the humidifier structure and not affect the air inlet at the lower part of the outer shell 1, the motor of the fan 4 is arranged in the outer shell 1 and is arranged above the fan 4, and then the motor 13 is in power connection with the fan blades. 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.
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.

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.

By adopting the evaporation device with the reducing structure, the folding layers of the small end with large density at the lower part are compact, the large end with small density at the upper part is sparse, and the running noise sound wave can effectively reduce and eliminate the running noise sound wave after passing through the evaporator by installing the fan at the lower part of the evaporator, thereby realizing silence; the diameter-variable evaporator with the lower end being tight and the upper section being loose can also improve the turbulence and mass transfer effect of air flow, so that liquid water on an evaporation device is easier to evaporate into water molecules, and the evaporation capacity of the humidifier is improved from 283ml/h to 435ml/h after the evaporation device with the diameter-variable structure is adopted in the laboratory test of the applicant. Meanwhile, as mentioned above, the folded layer at the lower small end of the evaporation device can intercept impurities in water more easily, so as to prevent the impurities from being evaporated along with liquid water.
Further, as shown in fig. 5 and fig. 6, in order to increase the fitting degree between the evaporator 3 and the water storage tank 6, in this embodiment, the inventor further provides a tapered surface 31 on the inner side of the upper portion of the evaporator 3, so that the tapered surface 31 can fit with the outer wall of the water storage tank 6; further, in order to ensure the stability of the evaporator 3 when being installed in the evaporation water tank 2, an annular step surface 32 may be further provided on the outer side of the lower portion of the evaporator 3, the lower end of the evaporator 3 may be placed in the evaporation water tank 2 by the annular step surface 32, and the upper portion of the evaporator 3 may be engaged with the evaporation water tank 2; the annular step surface 32 is formed at a right angle to the longitudinal section of the evaporator 3, thereby ensuring the stability of engagement with the notch of the evaporation water tank 2.

Furthermore, in order to facilitate water addition, a cover 10 may be installed on the top of the outer casing 1, the water storage tank 6 is disposed under the cover 10, and water can be added to the water storage tank 6 by uncovering the cover 10 or through a through hole on the cover 10, in this embodiment, the air outlet 7 may be designed on the outer side of the edge of the cover 10.
On the other hand, in order to suppress bacteria in the water in the humidifier, as a preferable configuration of the above embodiment, an ultraviolet sterilizing lamp may be further installed inside the evaporation water tank 2; referring to fig. 7, in the present embodiment, in order to improve the humidification efficiency of the humidifier, the inventor further installs a water heating device 12 at the lower part of the evaporation water tank 2, and a heating part of the water heating device 12 contacts with the bottom of the evaporation water tank 2 so as to heat the water in the evaporation water tank by means of heat transfer to improve the evaporation amount of the water passing through the evaporator 3, according to the experimental data of the inventor, when the water temperature on the evaporator 3 rises, the evaporation amount can be significantly improved, and according to the conventional test standard, in the environment with the air temperature of 23 ± 5 ℃, the indoor humidity is 30% ± 5%, the evaporation amount is 400ml/h, when the water temperature on the evaporator 3 reaches 35 ℃, the evaporation amount is 600ml/h, and when the water temperature reaches 38 ℃, the evaporation amount is 900 ml/h; therefore, by controlling the power and heating time of the water heating device 12, the water in the evaporation water tank 2 can be always kept in the temperature range of 30-39 ℃, thereby increasing the humidification amount.
Furthermore, the inventor has found through experiments that not only raising the water temperature helps to raise the humidification amount, but also raising the temperature of the inlet air can raise the humidification amount, and for this purpose, the air inlet 5 can be designed at the bottom of the outer casing 1, and then an air heating device 14 is installed at the bottom of the outer casing 1, and the air heating device 14 is disposed between the air inlet 5 and the air inlet end of the fan 4, that is, when the fan 4 rotates, the external airflow enters from the air inlet 5 and then contacts with the air heating device 14, and then enters into the airflow channel 11 and contacts with the evaporator 3, so as to raise the humidification amount.
