Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fan technology, specifically relating to a component for adjusting the airflow direction of a bladeless fan. Background Technology
[0002] The bladeless fan outlet flexibly adjusts the airflow direction by swinging the blade assembly, improving comfort. In contrast, the blade assembly in existing fans is prone to sagging after prolonged use. Therefore, the structure of the adjustment component for adjusting the airflow direction in existing fans is unstable, resulting in unstable airflow, uneven air delivery, and reduced fan efficiency. Utility Model Content
[0003] Solve the technical problem of unstable blade assembly structure in existing fan airflow adjustment.
[0004] To achieve the above objectives, the present invention provides the following technical solution: an assembly for a bladeless fan, comprising a housing body and a blade assembly, the blade assembly comprising a plurality of blades and a linkage rod, each blade having a connecting rod at one end near the linkage rod, each connecting rod being connected to the linkage rod, each blade having a connecting shaft at its edge, both ends of the connecting shaft extending to the outer side of the blade, each blade being disposed in the air outlet of the housing body, and the connecting shafts protruding from both ends of the blade being disposed in the side wall of the air outlet.
[0005] Furthermore, the blade assembly includes a stabilizing rod, each blade having an opening in it, and the bottom of the stabilizing rod having several hooks, which are located in the openings of each blade and connected to the connecting shaft of each blade.
[0006] Furthermore, the number of openings is set according to the length of the blade, and can be one or more. The number of stabilizer bars is set according to the number of openings.
[0007] Furthermore, one end of the stabilizer bar is inserted into the side wall of the air outlet, and the other end extends to the bottom of the air outlet and is connected to the main body of the housing.
[0008] The main advantages of this invention are as follows: A pusher is provided in the side wall of the linkage rod of the main body of the housing. The pusher is connected to the linkage rod. When the fan generates wind energy and outputs it outward from the air outlet, the pusher drives the linkage rod to swing. Simultaneously, the linkage rod drives each blade to rotate around the connecting shaft. The rotation of the blades changes the airflow direction, making the air distribution more even, thus improving the fan's air delivery effect, comfort, and energy efficiency. When the fan is not in use, the linkage rod enables the blades to close with the air outlet, preventing dust or other foreign objects from entering the fan. The blades are connected by a stabilizing rod, making the structure more stable during rotation and preventing unstable airflow and uneven air delivery caused by prolonged use, thus reducing fan efficiency.

[0015] like Figures 1 to 5 As shown, an assembly for a bladeless fan includes a housing body 10 and a blade assembly 20. The blade assembly 20 includes a plurality of blades 21 and a linkage rod 22. Each blade 21 has a connecting rod 23 at one end near the linkage rod 22. Each connecting rod 23 is connected to the linkage rod 22. Each blade 21 has a connecting shaft 24 along its edge. Both ends of the connecting shaft 24 extend to the outside of the blade 21. Each blade 21 is located in the air outlet 11 of the housing body 10. The connecting shafts 24 protruding from both ends of the blade 21 are located in the side wall of the air outlet 11.
[0016] In practical implementation, the housing body 10 has a pusher in the side wall of the linkage rod 22. The pusher is connected to the linkage rod 22. When the fan generates wind energy and outputs it outward from the air outlet 11, the pusher drives the linkage rod 22 to swing. The linkage rod 22 synchronously drives each blade 21 to rotate around the connecting shaft 24. The rotation of the blades 21 can change the airflow direction, making the air more evenly distributed, improving the fan's air delivery effect, comfort and energy-saving performance. When the fan is not in use, the linkage rod 22 can cause the blades 21 to form a closure with the air outlet 11, which can prevent dust or other foreign objects from entering the fan.
[0017] To make the blades 21 more stable and less prone to collapsing during the flipping process, the blade assembly 20 also includes a stabilizing rod 30. Each blade 21 has an opening 25 in it. The number of openings 25 is set according to the length of the blade 21, and can be one or more. The number of stabilizing rods 30 is set according to the number of openings 25. The bottom of the stabilizing rod 30 is provided with several hooks 31. The hooks 31 are located in the openings 25 of each blade 21 and are connected to the connecting shaft 24 that connects to each blade 21.
[0018] One end of the stabilizer bar 30 is inserted into the side wall of the air outlet 11, and the other end extends to the bottom of the air outlet 11 and is connected to the housing body 10. When in use, the blades 21 are connected by the stabilizer bar 30, so that the structure of the blades 21 is more stable when they are flipping, preventing the wind direction from becoming unstable and the air delivery from being uneven due to long-term use of the blades, thus reducing the efficiency of the fan.
