Wherein, the plurality of state indication lamps 241 are uniformly and spacedly distributed, and the covered angle thereof matches the rotation angle of the swing head assembly 1.

[0038] Specifically, the outer shell 21 of the embodiment is in a hollow circular truncated cone structure, and the fixing frame 22 is inserted into the inner side wall of the outer shell 21, and the fixing frame 22 is used for installing and fixing components such as the main control circuit board 23 and the indication circuit board 24. The fixing frame 22 can be fixed in the outer shell 21 by screws, that is, the fixing frame 22 can be positioned by screws and screw holes. The main control circuit board 23 is integrated with a motion control module and a signal processing module, for example, a button is arranged on the signal processing module, a user transmits a signal through the button, and the signal processing module sends a corresponding signal to the motion control module to make it work according to the corresponding instruction.

[0039] The embodiment realizes real-time dynamic adjustment of fan swing head by real-time detection of human body position by the radar sensor 25, in combination with the signal processing module and the motion control module of the main control circuit board 23. When the human body moves in the sensing range of the fan, the fan can quickly respond and adjust the wind direction to continuously provide a comfortable air supply experience, greatly improving the convenience and comfort of use. The plurality of state indication lamps 241 are distributed in the circumferential direction of the rotation axis of the swing head assembly 1, which can directly display the position of the current tracking angle, ensure that the air supply direction is synchronized with the human body activity track, avoid the coverage blind area caused by the traditional fixed angle swing head, and directly understand the running condition of the fan through the color or flashing mode of the indication lamp, thereby enhancing the ease of use and user experience of the product.

[0040] In the embodiment, the fixed frame 22 is provided with a plurality of first elastic buckles 221, the main control circuit board 23 is provided with a plurality of positioning clamping grooves 231 matched with the first elastic buckles 221, and the first elastic buckles 221 can be buckled in the positioning clamping grooves 231. Taking four first elastic buckles 221 as an example, the four first elastic buckles 221 are distributed in a rectangular shape on the fixed frame 22, and the positioning clamping grooves 231 are also provided with four corresponding positioning clamping grooves 231, and the four first elastic buckles 221 are buckled in the four positioning clamping grooves 231 respectively, forming four-point fixing of the main control circuit board 23.

[0041] The design of the first elastic buckle 221 and the positioning clamping groove 231 enables the main control circuit board 23 to be quickly and stably installed on the fixed frame 22 without the need for additional screws or other fasteners, which not only simplifies the installation process and improves work efficiency, but also makes subsequent disassembly and replacement extremely convenient and reduces maintenance costs. In addition, a plurality of positioning blocks can also be provided on the fixed frame 22, the end faces of the plurality of positioning blocks are in the same plane and are matched with the first elastic buckles 221, when the main control circuit board 23 is installed, one side of the main control circuit board 23 is abutted against the end face of the positioning block, and the other side is fixed by the first elastic buckle 221, thereby ensuring the installation accuracy.

[0042] In the embodiment, the fixed frame 22 is provided with an installation cavity 222, the indication circuit board 24 is inserted into the installation cavity 222, and the installation cavity 222 is provided with a first through hole 2221 opposite to a plurality of state indication lamps 241. The first through hole 2221 can be a plurality of corresponding state indication lamps 241, or it can be one covering a plurality of state indication lamps 241.

[0043] The insertion structure of the installation cavity 222 realizes the quick positioning and fixing of the indication circuit board 24, and at the same time, the insertion mode facilitates the direct replacement of the circuit board during later maintenance, reduces the disassembly complexity and maintenance cost. The position of the first through hole 2221 is aligned with the state indication lamp 241, which ensures that there is no obstruction or deflection when the light passes through the light cover body 26, and avoids the attenuation of the light signal caused by assembly error. In addition, the installation cavity 222 can also play a role in positioning and preventing mistakes, which can ensure that the indication circuit board 24 is installed in the correct position and avoid misinstallation.

[0044] It should be noted that the side wall of the shell 21 is provided with a second through hole 211 opposite to the first through hole 2221, and the light-transmitting cover 26 is installed on the second through hole 211. Through the alignment design of the second through hole 211 and the first through hole 2221, it is ensured that the light of the status indicator lamp 241 penetrates the light-transmitting cover 26 along the preset path, reduces the light scattering loss, and eliminates the shielding of the side wall of the shell 21 to the light signal. In addition, the installation interface of the light-transmitting cover 26 and the second through hole 211 forms a physical isolation layer, which prevents external dust and moisture from entering the interior of the shell 21 and affecting the electronic components. Moreover, the light-transmitting cover 26 is installed as an independent component on the second through hole 211, supporting quick disassembly and replacement, facilitating cleaning and maintenance, or adjusting the light-transmitting material according to requirements.

[0046] The limiting hole 223 facilitates the positioning of the radar sensor 25 and the connection between the radar sensor 25 and the main control circuit board 23. The second elastic buckle 224 realizes tool-free installation and disassembly of the radar sensor 25 through elastic deformation of itself. The buckle structure allows the radar sensor 25 to be quickly separated during maintenance without damaging the shell 21 or disassembling other components, facilitating fault diagnosis and component replacement.

[0047] In the embodiment, the top of the fixing frame 22 is provided with a device compartment 225, the inner side wall of the shell 21 is provided with an annular protrusion (not shown in the figure), the swing head assembly 1 is arranged in the device compartment 225, and the bottom of the fixing frame 22 abuts against the protrusion. The top of the device compartment 225 is further provided with an outer edge, and the outer edge abuts against the end of the shell 21, so that the disassembly of the fixing frame 22 is more convenient.

[0048] The device compartment 225 provides a special accommodating space for the swing head assembly 1, realizes the modular layout of the core components, avoids the volume redundancy caused by traditional dispersed installation, and significantly improves the overall structural compactness and space utilization. The protrusion serves as an axial limiting reference for the fixing frame 22, avoids the falling of the fixing frame 22, and improves the stability of the installation. In addition, the fixing frame 22 and the shell 21 form a circumferential contact through the protrusion, which enhances the structural torsional stiffness, suppresses the deformation of the shell 21 during the periodic swinging of the swing head assembly 1, and maintains the alignment state of sensitive components such as optical paths and circuits.

[0049] In the embodiment, the head-shaking assembly 1 comprises a wind wheel support 11 and a power module 12 for driving the wind wheel support 11 to rotate, and the power module 12 is installed in the equipment bin 225.

[0050] In the technical solution, the power module 12 is built in the equipment bin 225, which effectively integrates the mechanical connection between the driving unit and the wind wheel support 11, reduces the external space occupation, and improves the overall structural compactness of the equipment. The equipment bin 225 provides a standardized installation interface for the power module 12, supports quick disassembly and replacement of parts, and reduces maintenance costs.

[0051] In the embodiment, the lifting adjustment assembly 3 comprises a fixed sleeve 31, a telescopic rod 32 movably arranged in the fixed sleeve 31, and a locking knob 33 arranged on the fixed sleeve 31 and capable of abutting against the telescopic rod 32, and the fixed sleeve 31 is detachably connected with the housing 21.

[0052] The fixed sleeve 31 and the housing 21 are designed to be detachably connected, allowing quick separation or recombination of parts. The locking knob is locked by abutting against the telescopic rod 32, which can accurately control the lifting stroke of the telescopic rod 32. In combination with the guiding and restraining effect of the fixed sleeve 31, the deviation or shaking during the adjustment process is effectively prevented, and the stable operation of the equipment at the target height is ensured.

[0053] It should be noted that the main control circuit board 23 is arranged in the axial direction of the housing 21, and the indication circuit board 24 is perpendicular to the main control circuit board 23. The axial arrangement of the main control circuit board 23 can make full use of the longitudinal space of the housing 21, and is highly consistent with the form of the housing 21. The vertical installation of the indication circuit board 24 forms a three-dimensional cross layout, reduces the planar projection area, and improves the space utilization. This orthogonal structure is beneficial to integrating complex circuit systems in limited space.
