[0020] As shown in FIGS. 1 and 3, an air intake port (222) communicating with a water tank (30) is installed in the bottom portion of the upper cover (20), and a ring-shaped separator plate (221) is installed inside the upper cover (20), so that a ring-shaped air duct (223) can be provided inside the upper cover (20) due to the ring-shaped separator plate (221). By installing a ring-shaped separator plate (221) inside the upper cover (20) and forming a ring-shaped air duct (223) inside the upper cover (20) using the ring-shaped separator plate (221), the steam formed inside the water tank (30) through the heating plate (70) flows into the upper cover (20) through the air intake port (222), and the flow time inside the upper cover (20) can be effectively increased. Therefore, the temperature of the steam discharged out of the upper cover (20) through the air outlet port (211) can be lowered further, and the user can be made more comfortable when using a steam humidifier equipped with a fan on the bottom. In an embodiment provided by the present invention, the separator assembly (50) includes a first separator (51) installed between the housing (10) and the water tank (30) and a second separator (52) installed between the fan assembly (40) and the housing (10), and a guide portion (511) is provided at the top of the first separator (51), and air inside the first air duct (11) flows into the second air duct (12) through the guide portion (511). Through the first separator plate (51) installed between the housing (10) and the water tank (30) and the second separator plate (52) installed between the fan assembly (40) and the housing (10), the sealing and waterproofing performance of the fan assembly (40) inside the housing (10) can be effectively improved, thereby preventing the risk of water flowing into the fan assembly (40) during the process of adding water to the water tank (30), thus improving safety when the user uses the steam humidifier (100) equipped with a fan on the bottom.In addition, since the air flowing from inside the first air duct (11) to the second air duct (12) and into the upper cover (20) can be effectively guided through the guide part (511) installed on the upper part of the first separator plate (51), the accuracy of the air flowing from inside the first air duct (11) to the second air duct (12) and into the upper cover (20) can be improved, and the effect of accelerating the water vapor flow speed inside the upper cover (20) through the air flowing into the upper cover (20) can be ensured.

[0021] As illustrated in FIGS. 1 and 2, the fan assembly (40) includes a control board (42) installed inside the housing (10), a fan blade (41) electrically connected to the control board (42), and an installation housing (43) used to install the fan blade (41) at the bottom of the housing (10). In this embodiment, by installing the fan assembly (40) at the bottom of the housing (10), the fan blade (41) inside the fan assembly (40) and the control board (42) can be directly electrically connected. Since there is no need to run the wires electrically connecting the control board (42) and the fan blade (41) from the bottom of the housing (10) to the top of the housing (10), the situation where the wires are folded inside the housing (10) can be effectively prevented, and safety during use by the user can be increased. The bottom portion of the first separator plate (51) and the top portion of the installation housing (43) are fitted and fixed, and a heating plate (70) is further installed on the bottom portion of the housing (10), and the bottom portion of the installation housing and the second separator plate are fitted and fixed. In the embodiment provided by the present invention, by fitting and fixing the installation housing (43) of the fan blade (41) to the bottom portion of the first separator plate (51) and the second separator plate (52) inside the housing (10), the stability when connecting the installation housing (43), the first separator plate (51), and the housing (10) can be effectively improved, thereby preventing the fan blade (41) from becoming detached during rotation. In addition, by fitting and fixing the installation housing (43) of the fan blade (41) to the bottom portion of the first separator plate (51) and the second separator plate (52) inside the housing (10), the convenience during installation and operation between the fan assembly (40), the first separator plate (51), and the housing (10) can be effectively improved, thereby increasing the installation efficiency when installing the fan assembly (40) on the bottom portion of the housing (10).An installation plate (14) is further provided between the fan assembly (40) and the water tank (30), and an insulating cotton (80) capable of separating the water tank (30) and the fan assembly (40) is installed on the installation plate (14).
