[0019] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] To address the problems in the background technology, this utility model proposes a multi-purpose fan structure, including a head assembly.

[0022] The head assembly is provided with a lifting and hanging component for suspending the head assembly on the wall surface;

[0023] The bottom of the head assembly is provided with a detachable connection mechanism, through which the head assembly can be selectively connected to a tabletop support module or a vertical module.

[0024] The tabletop support module is used to support the head assembly to be placed horizontally, and the vertical module is used to support the head assembly to be fixed vertically to the ground.

[0025] Combined with reference Figures 1 to 3 As shown, in this embodiment, the modular design enables the conversion between wall fan, table fan, and standing fan functions. The structure is primarily composed of a head assembly, which includes the basic components of a conventional fan, such as a protective mesh cover, back cover, drive unit, and fan blade assembly. A lifting and hanging component is fixedly installed on the top or back of the head assembly. This component uses an integrated hook structure or a rotatable hanging ring, and its load-bearing capacity allows it to directly suspend the entire fan on a pre-installed hook on the wall. In this position, the fan operates vertically, achieving the wall fan function.

[0026] In addition, the bottom of the head assembly features a detachable connection mechanism, allowing it to be selectively connected to either the tabletop support module or the vertical module as needed. The detachable connection mechanism can be designed with threaded, snap-fit, or plug-in connections, ensuring a secure connection while facilitating disassembly and replacement. Users can quickly switch between different support methods to suit various usage scenarios. The tabletop support module supports the head assembly, allowing it to be placed horizontally on a desktop or other level surface. It includes a stable base to firmly support the head assembly, preventing the fan from tilting or falling. The tabletop support module is suitable for desktops or office desks, providing stable support without taking up too much space. The vertical module also supports the head assembly, allowing it to be vertically fixed to the ground. It includes a bracket or base designed to ensure the head assembly stands vertically without tilting or collapsing. The vertical module is suitable for scenarios where the fan needs to be upright on the ground, such as open areas in homes or offices, providing convenient airflow coverage.

[0027] When switching working modes, users only need to disconnect the connection mechanism: in wall fan mode, it is directly suspended without any additional modules; in table fan mode, the tabletop support module is installed and placed on a flat surface; in standing fan mode, the standing module is connected and vertically fixed to the ground. All electrical wiring is built into the head assembly, and module replacement does not involve circuit disassembly. Users can flexibly choose the lifting and hanging parts, tabletop support module, or standing module according to different usage needs, meeting the requirements of users in different environments.

[0028] In one possible implementation, the detachable connection mechanism includes a connecting post integrally extended to the bottom of the rear housing of the head assembly, and a threaded hole opened at the bottom end of the connecting post.

[0029] Combined with reference Figure 2 or Figure 3 As shown, in this embodiment, a columnar connecting post is integrally formed at the bottom of the head assembly's rear shell through injection molding. The axis of this connecting post is perpendicular to the horizontal plane. The connecting post extends downward from the bottom of the head assembly's rear shell in a direction perpendicular to the wall surface, and its length is configured to significantly exceed the outer contour of the head assembly. A standard threaded hole is axially formed at the center of its bottom end, and an annular stress-dispersing boss is provided at the connection between its top and the bottom surface of the rear shell to prevent cracking of the injection-molded part during tightening. Alternatively, a metal insert nut can be injected into the hole and encapsulated with glue. The insert nut has an internal thread at its center, forming a mechanical interlocking structure after cooling.

[0030] In one possible implementation, the tabletop support module includes a support base and a first threaded connector adapted to the threaded hole. The first threaded connector is fixed to the top surface of the support base for screwing and fixing with the threaded hole.

[0031] Combined with reference Figure 2 As shown, in this embodiment, the support base is an ABS engineering plastic base with an anti-slip silicone pad on the bottom. An assembly hole is provided at the center of its top surface. The diameter of the stud of the first threaded connector is compatible with the threaded hole specification of the fan body connecting column. The head of the connector is fixed to a pre-embedded stainless steel bushing inside the assembly hole by laser welding, preventing loosening during use when the connector is screwed into the threaded hole of the fan body.

[0032] In one possible implementation, the vertical module includes a tripod and a second threaded connector adapted to the threaded hole, the second threaded connector being fixed to the top of the tripod for screwing into the threaded hole.

[0033] Combined with reference Figure 3 As shown, in this embodiment, the tripod consists of three aluminum alloy legs connected by hinges evenly spaced at 120° intervals, with the tops of the legs converging at the top flange. The second threaded connector is a stainless steel stud, its lower end welded to the center of the flange, and its upper end machined with a standard external thread that mates with the threaded hole of the fan body connecting post. Furthermore, anti-slip pads are fitted to the ends of the tripod legs to test the sliding resistance on a tiled floor.

[0034] In one possible implementation, the head assembly includes an air outlet grille with a clearance groove formed at its bottom. The shape of the clearance groove is adapted to the contour of the connecting post. The connecting post extends axially through the clearance groove to the bottom of the air outlet grille. Specifically, the air outlet grille has a U-shaped clearance groove stamped at its bottom. Its contour maintains a gap with the cylindrical outer surface of the connecting post. The connecting post extends vertically from the bottom of the rear housing, axially penetrating the central area of ​​the clearance groove, ensuring interference-free assembly and maintaining the aesthetic appearance of the fan.
