Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, and in particular to a multifunctional bladeless fan. Background Technology

[0002] As an innovative air conditioning device, the bladeless fan generates airflow through an internal turbine device in its base and uses a ring-shaped guide structure to uniformly accelerate the airflow before outputting it. Compared with traditional fan blade structures, it has higher safety and gentler airflow.

[0003] Existing bladeless fan products generally suffer from low functional integration and insufficient expandability: on the one hand, traditional bladeless fans only have a single air supply function, which cannot meet users' needs for multi-functional integration of smart home devices; on the other hand, the few products that attempt to integrate additional functions mostly adopt a fixed built-in structure, which has problems such as non-replaceable functional modules, difficult maintenance, and occupation of air duct space. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a multifunctional bladeless fan, which features convenient replacement of functional modules and a compact structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A multi-functional bladeless fan includes a frame, a detachable multi-functional module disposed on the frame, a fan assembly disposed within the frame, and a recessed mounting platform for mounting the multi-functional module is provided on the frame, with an air outlet communicating with the fan assembly around the mounting platform.

[0007] The mounting platform has a first connector evenly arranged on its ring wall. The multifunctional module includes a mounting base and a second connector is provided on the mounting base. The multifunctional module can be fixedly mounted on the mounting platform by tightening the second connector with the first connector.

[0008] The first connector is cylindrical, with one end of the cylinder fixed to the ring wall of the mounting platform. The second connector is a wedge block disposed around the mounting base. The wedge block has an inclined surface on its upper part. When the inclined surface abuts against the first connector and rotates, the mounting base can be tightened onto the mounting platform.

[0009] Each inclined surface is provided with a number of ridges, and the direction of each ridge is perpendicular to the upward direction of the inclined surface.

[0010] The fan assembly includes an air guide cavity disposed at the bottom of the frame and a turbine fan disposed in the middle of the air guide cavity, the air guide cavity being connected to the air outlet.

[0011] The peripheral wall of the air guide cavity is circular, and several first air guide fins are evenly arranged on its peripheral wall.

[0012] The air outlet is arranged in a ring on the upper surface of the frame, and second air guide fins are evenly arranged inside the air outlet.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up a topological structure design with a centrally detachable multi-functional module and a sunken mounting platform, the device achieves a high degree of expandability. Users can quickly replace modules such as speakers and air purifiers by tightening the fastening mechanism (first connector and second connector), breaking through the technical limitations of the single function of traditional bladeless fans, while avoiding the problem of built-in modules encroaching on the air duct space in existing technologies.

[0015] 2. The wedge-shaped blocks on the periphery of the mounting base cooperate with the cylindrical first connector. Through the action of the inclined surface and the upper rib, quick disassembly and assembly are achieved, while the frictional self-locking effectively prevents the module from resonating and falling off.

[0016] 3. The layout of the annular air outlet surrounding the central module maintains the integrity of the air outlet structure while avoiding interference from additional modules in the air outlet path through the three-dimensional spatial arrangement of the sunken mounting platform. The centralized layout of the air guide cavity and turbine fan at the bottom, combined with the circumferential flow uniformity design of the first air guide fin, significantly reduces air pressure loss and ensures that the air duct system is not affected during module replacement.

[0023] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0024] Reference Figure 1 , Figure 2 This utility model proposes a multi-functional bladeless fan, including a frame 1, a detachable multi-functional module 2 disposed on the frame 1, a fan assembly 11 disposed in the frame 1, and a recessed mounting platform 10 for mounting the multi-functional module 2 on the frame 1. An air outlet 12 communicating with the fan assembly 11 is opened around the mounting platform 10.

[0025] The mounting platform 10 has first connectors 100 evenly arranged on its ring wall. The multi-functional module 2 includes a mounting base 20 and a second connector 21. By tightening the second connector 21 with the first connector 100, the multi-functional module 2 can be fixedly mounted on the mounting platform 10.

[0026] Specifically, by designing a topological structure with a centrally detachable multi-functional module 12 and a sunken mounting platform 10, the device achieves a high degree of functional expandability. Users can quickly replace modules such as speakers and air purifiers by tightening the fastening mechanism (first connector 100 and second connector 21), overcoming the technical limitations of traditional bladeless fans with their single function, while avoiding the problem of built-in modules encroaching on the air duct space in existing technologies. Furthermore, since the multi-functional module 12 is detachable, when designing other functions, only the compatibility of the mounting base 20 needs to be considered, without considering the overall bladeless fan.

[0027] Reference Figure 3 The first connector 100 is cylindrical, with one end of the cylinder fixed to the ring wall of the mounting platform 10. The second connector 21 is a wedge block disposed around the mounting base 20. An inclined surface 210 is provided on the upper part of the wedge block. When the inclined surface 210 abuts against the first connector 100 and rotates, the mounting base 20 can be tightened to the mounting platform 10.

[0028] Furthermore, the inclined surface 210 is provided with a number of ribs 211, and the direction of each rib 211 is perpendicular to the upward direction of the inclined surface 210.

[0029] Specifically, the wedge-shaped blocks on the periphery of the mounting base 20 cooperate with the cylindrical first connector 100. Through the action of the inclined surface 210 and the upper rib 211, quick assembly and disassembly are achieved, while the self-locking effect of friction effectively prevents the mounting base 20 from resonating and falling off. Furthermore, the coordinated design of the inclined surface 210 and the rib 211 generates progressive tactile feedback during tightening, increasing the accuracy of the installation process and resulting in greater stability after installation.

[0030] Reference Figures 4-6 The fan assembly 11 includes an air guide cavity 111 disposed in the bottom of the frame 1, a turbine fan 110 disposed in the middle of the air guide cavity 111, and the air guide cavity 111 is connected to the air outlet 12.

[0031] The air guide cavity 111 has a circular perimeter wall, on which a plurality of first air guide fins 112 are evenly arranged. The air outlet 12 is arranged in a ring on the upper surface of the frame 1, and second air guide fins 120 are evenly arranged inside the air outlet 12.

[0032] Specifically, the layout of the annular air outlet 12 surrounding the central multi-functional module 12 maintains the integrity of the air outlet structure while avoiding interference from additional modules on the air outlet path through the three-dimensional spatial arrangement of the sunken mounting platform 10. The bottom-mounted arrangement of the air guide cavity 111 and the turbine fan 110, combined with the circumferential flow uniformity design of the first air guide fin 112, significantly reduces air pressure loss and ensures that the air duct system is not affected during the replacement of the multi-functional module 12. Furthermore, the first air guide fin 112 is installed on the periphery of the air guide cavity 111 to achieve primary airflow rectification, and the second air guide fin 120 is installed in the air outlet 12 for secondary airflow direction orientation. This design results in smaller fluctuations in the air outlet velocity and effectively eliminates turbulent noise caused by the multi-functional module 2 occupying the air duct.
