[0038] Combination Figure 1-Figure 7As shown, in some embodiments, the humidification device includes: a housing 100, a wet film 200 and a centrifugal fan 300. The housing 100 defines an airflow cavity; the wet film 200 is disposed in the airflow cavity, and the axis of the wet film 200 is perpendicular to the horizontal plane; the centrifugal fan 300 is disposed above the wet film 200, and the air inlet 301 of the centrifugal fan 300 is disposed toward the upper end of the wet film 200.
[0039] The humidifying device provided by the embodiment of the present disclosure is adopted, by setting the wet film 200 and the centrifugal fan 300 of the cylindrical structure, and setting the air inlet 301 of the centrifugal fan 300 toward the upper port of the wet film 200, and utilizing the characteristics of the centrifugal fan 300 of axial air intake and radial air discharge, to generate negative pressure in the inner annular space of the wet film 200, so that the outer peripheral wall of the wet film 200 is the air intake area. The airflow in the outer peripheral wall area of the wet film 200 flows to the inner annular space of the wet film 200 under the action of negative pressure, thereby increasing the airflow passing through the wet film 200, increasing the evaporation amount of the wet film 200, and thus improving the humidification effect.
[0040] It can be understood that the upper port of the wet film 200 refers to the port of the upper annular surface of the wet film 200 of the cylindrical structure.
[0041] Optionally, multiple vertical side walls of the housing 100 are provided with flow openings 110, and each flow opening 110 corresponds to a different area of the outer peripheral wall of the wet film 200. In this way, by providing the flow openings 110 on multiple vertical side walls of the housing 100, the airflow outside the housing 100 can be blown to different areas of the outer peripheral wall of the wet film 200 from multiple directions, thereby increasing the amount of airflow blown to the wet film 200, thereby improving the evaporation efficiency of the wet film 200 and improving the humidification effect of the humidifying device.
[0042] Optionally, the flow opening 110 is provided in the lower area of the outer peripheral wall of the wet film 200 corresponding to the vertical side wall of the housing 100. In this way, the airflow flowing into the flow opening 110 can be blown to the lower area of the outer peripheral wall of the wet film 200, and then gradually contact with most of the outer peripheral wall of the wet film 200 in the process of gradually flowing upward, thereby improving the evaporation effect of the wet film 200.

An air inlet 301 is provided on the side wall of the volute 310; the centrifugal impeller 320 is rotatably provided inside the volute 310, and the axis of the centrifugal impeller 320 coincides with the axis of the wet film 200. In this way, the centrifugal impeller 320 rotates inside the volute 310 to generate negative pressure, and the negative pressure acts on the inner annular space of the wet film 200 through the air inlet 301 provided on the side wall of the volute 310, so that the airflow in the outer peripheral wall area of the wet film 200 flows through the outer peripheral wall of the wet film 200, thereby accelerating the evaporation of water in the wet film 200. The axis of the centrifugal impeller 320 is set to coincide with the axis of the wet film 200, so that the negative pressure at the air inlet 301 acts more evenly on the inner annular space of the wet film 200, and the airflow in the outer peripheral wall area of the wet film 200 flows evenly to the inside of the wet film 200, so that the overall water evaporation of the wet film 200 is more uniform, thereby improving the uniformity of humidification.
[0044] Specifically, the air inlet 301 is provided on the axial side wall of the volute 310 , and the air inlet 301 provided on the axial side wall of the volute 310 is the air inlet 301 of the centrifugal fan 300 .

In this way, the volute 310 of the centrifugal fan 300 is installed through the annular seat 130, and the annular seat 130 is supported by the assembly plate 120 covering the opening of the upper side wall of the housing 100, thereby improving the stability of the centrifugal fan 300 and reducing the shaking and noise generated by the centrifugal fan 300 during operation. The axis of the air inlet 301 of the volute 310 is overlapped with the axis of the annular seat 130 , so that the air inlet 301 of the volute 310 is located directly above the annular seat 130 , thereby preventing the annular seat 130 from blocking the airflow at the air inlet 301 .
[0046] Optionally, the annular seat 130 is located directly above the wet film 200, and the axis of the annular seat 130 coincides with the axis of the wet film 200. In this way, when the volute 310 is installed through the annular seat 130, the volute 310 is positioned through the annular seat 130, so that the negative pressure at the air inlet 301 can act more evenly in the inner annular space of the wet film 200.
[0047] Optionally, a rubber gasket 140 is provided on the upper ring surface of the annular seat 130. When the volute 310 is installed above the annular seat 130, the rubber gasket 140 is located between the edge of the air inlet 301 of the volute 310 and the upper ring surface of the annular seat 130. In this way, by providing the rubber gasket 140, the assembly sealing performance of the annular seat 130 and the air inlet 301 can be improved, and vibration reduction can be provided at the same time, thereby reducing the vibration and noise generated by the centrifugal fan 300 during operation.
[0048] Optionally, a buckle is provided on the lower side wall of the assembly plate 120, and a slot is provided on the inner wall corresponding to the open edge of the housing 100, and the buckle is locked in the slot to connect the assembly plate 120 to the housing 100.

In this way, the mounting ears 311 are connected to the threaded seats 131 by screws to assemble the volute 310 of the centrifugal fan 300. Through the cooperation of the mounting ears 311 and the threaded seats 131, the centrifugal fan 300 is more stably installed above the annular seat 130, thereby improving the stability of the centrifugal fan 300 and facilitating the disassembly and maintenance of the centrifugal fan 300.

In this way, water can be stored through the annular water box 132, and water is sprayed to the wet film 200 below using the plurality of water leakage holes at the bottom of the annular water tank, so that the wet film 200 is soaked from top to bottom, and the evaporation of the wet film 200 is accelerated under the action of the incoming air flow, and the evaporation amount of the wet film 200 is further increased, thereby improving the humidification effect. The setting of the annular water box 132 can be adapted to the shape of the upper annular surface of the wet film 200, and the water in the annular water tank is evenly sprayed on the upper end of the wet film 200 through a plurality of evenly distributed water leakage holes, so that the wet film 200 is more evenly soaked by the sprayed water, thereby improving the humidification uniformity of the wet film 200.
[0052] Optionally, an annular storage space is defined between the inner annular surface of the annular seat 130 and the outer annular surface of the annular water box 132, and part of the upper annular surface of the wet film 200 extends into the annular storage space. In this way, in order to improve the assembly stability of the wet film 200 and the annular water box 132, the lower annular surface of the annular water box 132 is pressed against the upper annular surface of the wet film 200. An annular storage space is defined between the inner annular surface of the annular seat 130 and the outer annular surface of the annular water box 132, so that the part of the upper annular surface of the wet film 200 located on the outer ring side of the annular water box 132 can be pressed and deformed to extend into the annular storage space, so as to form a wrapping effect on the lower annular surface of the annular water box 132, so that the water flowing out of the annular water box 132 flows into the wet film 200 more evenly, reducing the risk of water leakage.
[0053] Optionally, a normal temperature water tank 150 is provided on the lower inner wall of the housing 100, and the lower end of the wet film 200 is soaked in the normal temperature water tank 150.

[0055] Optionally, the mounting seat 151 is a discontinuous annular structure, and the axis of the mounting seat 151 coincides with the axis of the wet film 200. In this way, the overall shape of the mounting seat 151 is adapted to the shape of the lower end of the wet film 200, further improving the installation stability of the wet film 200.

When the water pump 161 is not working, the lower end of the wet film 200 absorbs normal temperature water for humidification, which can adapt to the humidification environment with a small humidification demand. When the water pump 161 is working and the water in the temperature-controlled water tank 160 is room temperature water, the lower end of the wet film 200 absorbs room temperature water, and the upper end of the wet film 200 sprays room temperature water for humidification, which can adapt to a humidification environment with a relatively moderate humidification demand.
