[0002] In the current prior art, a humidifying fan includes a fogging device connecting pipe fitting, a humidifying device, a support column, a fan head and a base. The fan head is composed of a motor, a wind blade, a rear grille, a front grille and a spray head. The motor shaft of the motor is made in a hollow structural form, and the spray head is arranged on the motor shaft. The spray head is connected to the fog outlet of the humidifying device through the fogging device connecting pipe fitting. At the same time, in order to prevent the fogging device connecting pipe fitting between the humidifying device and the spray head from being exposed outside or in front of the humidifying fan, the fogging device connecting pipe fitting is arranged along the inner cavity of the support column and the inner cavity of the hollow shaft of the motor or between the motor housing and the motor. The water vapor atomized by the humidifying device is sent to the spray head through the fogging device connecting pipe fitting for humidification.

[0003] However, due to the arrangement of the fogging device connecting pipe fitting in the above-mentioned humidifying fan, the rotatable angle of the fan head is limited, resulting in a small blowing and humidifying area of the fan, which cannot meet the requirements of users.

[0004] Correspondingly, the field needs a new technical solution to solve the above problems. Summary of the Utility Model

[0005] The utility model aims to solve the above technical problems, that is, to solve the problem that the rotatable angle of the fan head is limited, resulting in a small blowing and humidifying area of the fan, which cannot meet the requirements of users.

[0013] In the case of adopting the above technical solution, through the setting of the ultrasonic atomization device and the first transmission pipe, the effective generation and transmission of water mist are realized. The ultrasonic atomization device provides a continuous and stable humidifying source for the fan, improving the humidifying effect.

[0014] In the specific embodiment of the above humidifying fan, the rotary support further includes a hollow support cylinder. The first connecting portion and the second connecting portion are mirror-symmetrically arranged on both sides of the support cylinder. A cavity communicating with the inner cavity of the support cylinder is arranged inside the first connecting portion. The first transmission pipe is configured to be able to pass through the inner cavity of the first connecting portion and the inner cavity of the support cylinder.

[0015] In the case of adopting the above technical solution, a hollow structure is provided inside the rotary support, enabling the first transmission pipeline to pass through it, which not only saves space but also ensures the concealment and safety of the transmission pipeline.

[0017] In the case of adopting the above technical solution, the setting of the rotating assembly enables the fan head to rotate relative to the bracket, further increasing the flexibility of the fan's use. At the same time, the channel inside the rotating bracket provides a stable passing path for the first transmission pipeline.

[0018] In the specific implementation manner of the above humidifying fan, the fan head includes a hollow fog guide shaft arranged along the air flow direction. One end of the hollow fog guide shaft is communicated with the pipeline connector, and a fog outlet head is arranged at the other end of the hollow fog guide shaft.

[0019] In the case of adopting the above technical solution, the setting of the hollow fog guide shaft enables the water mist to smoothly transfer from the humidifying pipe to the fog outlet head, reducing the loss of the water mist.

[0020] In the specific implementation manner of the above humidifying fan, the fog outlet head includes a reducing pipe and a fog outlet protection cover. The inner diameter of part of the reducing pipe gradually increases along the flow direction of the water mist, and the upstream end of the reducing pipe is communicated with the hollow fog guide shaft; the fog outlet protection cover is communicated with the downstream end of the reducing pipe, and a plurality of fog outlet holes are arranged on the fog outlet protection cover.

[0021] In the case of adopting the above technical solution, the design of the reducing pipe enables the water mist to gradually diffuse when flowing out, improving the uniformity of humidification. The plurality of fog outlet holes on the fog outlet protection cover further ensures the uniform distribution of the water mist.

[0022] In the specific implementation manner of the above humidifying fan, the fan head includes an outer cylinder and a front net cover. The outer cylinder is open in the direction of the air flow, the front net cover is communicated with the air outlet end of the outer cylinder, and a fog outlet mounting hole for mounting the fog outlet protection cover is arranged at the central position of the front net cover.

[0023] In the case of adopting the above technical solution, the setting of the outer cylinder and the front net cover not only provides stable structural support for the fan head but also provides a suitable mounting position for the fog outlet protection cover through the fog outlet mounting hole on the front net cover, making the design of the entire humidifying fan more compact and reasonable.

[0024] In the specific implementation manner of the above humidifying fan, the humidifying component includes a second transmission pipeline. One end of the second transmission pipeline is connected to the hollow mist guide shaft, and the other end is communicated with the pipeline connector; and / or

The pipeline connector is arranged on the inner layer of the outer cylinder. The humidifying pipe passes through the rotating collar and is rotatably and sealingly connected to the pipeline connector.

[0026] In the case of adopting the above technical solution, the setting of the second transmission pipeline further ensures the smooth transmission of the water mist from the humidifying pipe to the hollow mist guide shaft. At the same time, the double-layer setting of the outer cylinder and the use of the rotating collar make the connection between the humidifying pipe and the fan head more stable and flexible. The pipeline connector is arranged on the inner layer of the outer cylinder to avoid damage to the pipeline connector. BRIEF DESCRIPTION OF THE DRAWINGS
