[0006] Through this setting method, the fan assembly is installed in the installation box, and the user controls the fan assembly through the controller on the top of the installation box. The fixed frame in the installation box plays a supporting role, and the panel assembly outside the fixed frame plays a protective role for the fan assembly to avoid foreign objects from intruding or the user from accidentally touching the fan assembly during use in the middle or bottom layers. The user can install the fan assembly in any required scene through the installation box, and the mounting parts act on the installation box without affecting the normal operation of the fan assembly. The power supply can be a built-in power supply or an external power supply, so this multi-purpose fan can be suitable for a variety of usage scenarios.

[0007] The fixing frame acts as a skeleton support inside the installation box, which is beneficial to improving the structural strength of the installation box, and the fan assembly is limited by the fixing frame to ensure a firm connection between the installation box and the fan assembly. The panel assembly covers the outside of the installation box, and the user can control the operation of the fan assembly through the panel assembly, thereby improving operational convenience; and the panel assembly also plays a dust-proof protection role for the fan assembly, which is beneficial to increasing the life of the equipment.

[0008] Preferably, a plurality of ventilation holes are provided on the ventilation plate, and the air inlet of the fan assembly is connected to the outside through the ventilation holes.

[0009] Through this setting, the ventilation plate can not only protect the fan assembly in the fixed frame to prevent foreign objects from entering or the operator from accidentally touching the working fan assembly, but also the several ventilation holes on the ventilation plate can form an air flow channel to reduce the impact of the ventilation plate on the air intake of the fan assembly.

[0010] Preferably, the plurality of ventilation holes are arranged in a rectangular array on the ventilation plate.

[0011] Preferably, a dust cover is further provided on the outside of the ventilation plate.

[0012] Preferably, an air outlet hole is provided on the air outlet plate, and the air outlet of the fan assembly is connected to the air outlet hole.

[0013] Through this setting, the wind blown out from the air outlet of the fan assembly can act on the outside through the air outlet. The air outlet plate can prevent foreign objects from entering the fixed frame and affecting the operation of the fan assembly, and will not affect the blowing of the fan assembly.

[0014] Preferably, it further comprises a plurality of universal wheels, and the plurality of universal wheels are all installed at the bottom of the installation box.

[0015] With this arrangement, when frequent movement is required, universal wheels can be installed at the bottom of the base plate to conveniently move the fan; when hanging use is required, the universal wheels can be removed and the installation box can be directly installed in the suspended installation position.

[0017] Preferably, the universal wheel is provided with a locking mechanism for locking the universal wheel from rotating. With this arrangement, when the fan is moved to a location where it is needed, the user can lock the universal wheel through the locking mechanism to prevent the fan assembly from moving due to reaction force during operation.

[0018] Preferably, the controller includes a touch panel and an electric control box, the touch panel is fixedly installed on the top of the fixing frame, the electric control box is fixedly installed on the lower side of the touch panel, and the electric control box is electrically connected to the touch panel.

The motor is fixedly connected to the turbine shell through the mounting frame, and the air outlet is opened on the side of the turbine shell.

[0022] With this setting, when the fan assembly is working, the motor drives the blade ring to rotate inside the turbine shell. The rotation of the blade ring drives the air flow, attracting the air near the air inlet into the blade ring and the vortex shell. The airflow rotates along the inner wall of the vortex shell and is finally discharged at the air outlet on the side wall of the vortex shell, thereby blowing air to the outside.

[0023] Preferably, the blade ring can also be directly sleeved on the output shaft of the motor.

An installation position for fixing the power box is formed between the side of the supporting bracket, the top of the turbine shell and the fixed frame.

[0028] Through this setting method, the power supply can be installed in the power box, which improves the convenience of using the fan device. The power box is limited by the support bracket, turbine shell and fixed frame to ensure that the power box is installed firmly and avoid the power box falling off due to the high power quality.

[0029] Preferably, the fixing frame includes a plurality of profiles and connectors, and the plurality of profiles are fixedly connected to each other through the connectors to form a cubic structure.

[0030] With this setting method, the fixed frame of the cube structure is easy to place without the need for a special installation structure. It can match the installation position of most scenarios, which is conducive to improving practicality.

[0031] Preferably, the panel assembly is further provided with a lighting element, which can provide lighting during use or feedback the working status through light of different colors, and also play an aesthetic role.
