In addition, based on the above structure, a water tank 5 can be further installed on the side surface of the outer shell 1, the water tank 5 is designed by being attached to the outer shell 1, and the water tank 5 is communicated with the water storage tank 2 through a water inlet pipeline, so that water stored in the water tank 5 can flow into the water storage tank 2 and be absorbed by the evaporator 11; an air outlet 6 is arranged above the outer shell 1, the air outlet 6 is communicated with the air outlet end of the fan 3, so that the evaporator 11 is arranged between the air outlet 6 and the air outlet end of the fan 3. Therefore, when the fan 3 rotates, air enters from the air inlet 4, passes through the air filter element 12, passes through the evaporator 11 and is discharged from the air outlet 6, and in the process, the fan 3 rotates in the outer shell to blow out moisture on the evaporator 11 from the air outlet 6, so that the indoor humidification and air filtration purification functions are achieved; at the same time, since the sound wave is also influenced by the air flow, the noise generated by the operation of the motor 10 of the fan 3 enters the evaporator 11 along with the air flow, and the noise wave is absorbed and isolated by the evaporator.

Based on the above embodiment, it is preferable that the air filter 12 is disposed directly below the fan 3 as shown in fig. 2, and the fan 3 is disposed between the evaporator 11 and the air filter 12, to reduce the wind resistance in the outer case 1, thereby reducing noise while keeping the internal structure of the all-in-one compact. And in order to conveniently replace the air filter element 15, a hole can be opened on the side surface of the outer shell 1, and a filter element detaching door 16 is installed. Based on the above thought, when the air outlet 6, the fan 3, the evaporator 11 and the air filter element 12 are installed in the outer shell 1, the overlapped installation is carried out on the same straight line perpendicular to the horizontal plane, so that the air flow channel can be communicated with the four air flow channels at the shortest distance, the humidification efficiency and the air filtration efficiency can be improved, and the noise generated during the operation of the all-in-one machine can be further reduced.

Referring to fig. 2 again, in a more preferred embodiment of the present invention for solving the technical problem, the water tank 5 may be directly designed to be an annular structure and then surround the outer shell 1, or the inner wall of the annular water tank 5 may be directly used as the outer shell 1, such a design mode may further reduce the overall volume of the humidifier on the basis of ensuring the volume of the water tank 5; on the other hand, for avoiding the water yield in the aqua storage tank 2 too much to lead to overflowing, still add a mechanical valve 13 on the inlet channel between aqua storage tank 2 and water tank 5, the principle of the usable stopper valve that floats of this mechanical valve 13, when aqua storage tank 2 has the rated water yield, then close the inhalant canal, when the water yield in aqua storage tank 2 is not enough, then open inhalant canal, thereby make the water yield in aqua storage tank 2 keep invariable all the time, thereby make the volume of humidifying keep invariable, do not receive the influence of liquid level in the water tank 5.

As shown in fig. 3, to facilitate water addition, an annular water chute 12 may be additionally disposed at an upper portion of the outer casing 1, the annular water chute 12 is communicated with the water tank 5 through a water adding opening 7, then an arc cover 8 is mounted at the upper portion of the outer casing 1, an edge of the arc cover 8 extends to a position right above the annular water chute 12, and a gap air outlet 6 between the edge of the arc cover 8 and the outer casing 1 is used as the air outlet 6.

Similar to the above structure, a water filling opening 7 can be added directly on the water tank 5, then a cambered cover body 8 is installed on the upper part of the outer shell 1, the edge of the cambered cover body 8 extends to the right above the water filling opening 7, and the preferable structure of the water filling opening 7 is an annular opening structure matched with the structure of the annular water tank 5; in this embodiment, the gap between the edge of the arc cover 8 and the outer casing 1 may be used as the air outlet 6.

Therefore, in the structure described in the present embodiment, both the water and the air are added through the gap between the edge of the arc cover 8 and the outer shell 1, but it should be noted that this does not mean that the air flow channel and the water flow channel are the same channel in the humidifier, and it should be understood that the air flow channel and the water flow channel have the same outlet.

On the other hand, based on the above-mentioned structural design, the evaporator 11 may be designed to be cylindrical, and an annular airflow channel 9 is formed between the evaporator 11 and the outer casing 1, the airflow channel 9 is communicated with the air outlet 6, and the airflow generated by the fan 3 enters the evaporator 11 through the airflow channel 9 and is then discharged through the air outlet 6; preferably, the evaporator 11 used in this embodiment may directly use a cylindrical fiber filter element in the current mainstream air purifier, the fiber filter element may allow water in the water storage tank 2 to permeate from the lower portion to the upper portion through capillary phenomenon, and evaporate under the action of the positive pressure air flow, and the fiber filter element also has better isolation and absorption effects on noise waves, so that the fiber filter element may be periodically replaced as a consumable in the use of the humidifier.

In another preferred embodiment of the present invention for solving the above-mentioned problems, an ultraviolet sterilizing lamp may be further installed inside the water storage tank 2 as a preferred structure of the above-mentioned embodiment in order to suppress bacteria in the water in the humidifier. Meanwhile, for further increasing the humidification amount of the humidifier, experiments show that after the temperature of the water in the water storage tank is increased, the humidification amount in unit time can be significantly increased, according to the test standards in national standard GBGB/T23332-2018 and GB 21551.2-2010, in the environment with the air temperature of 23 ± 5 ℃, the indoor humidity is 30% ± 5%, at this time, 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 900ml/h, therefore, based on the aforementioned test results, referring to fig. 4, the inventor installs the first heater 14 at the lower part of the water storage tank 2, and the heating part of the first heater 14 is in contact with the bottom part of the water storage tank 2, so as to heat the water in the water storage tank by means of heat transfer, so as to increase the evaporation amount of the water passing through the evaporator 11, the humidifying quantity is increased by keeping the water in the water storage tank 2 in the temperature range of 30-38 ℃.

Further, 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 intake air can raise the humidification amount, and for this purpose, the air inlet 4 can be designed at the bottom of the outer casing 1, and then a second heater 15 is installed inside the outer casing 1, and the second heater 15 is disposed between the air inlet end of the fan 3 and the air filter element 12, that is, when the fan 3 rotates, the external airflow enters from the air inlet 4, is first filtered by the air filter element 12, then contacts with the second heater 15, and enters into the airflow channel 9 to contact with the evaporator 3 after raising the temperature, and then raises the humidification amount.
