Embodiment Construction

[0046] The above-mentioned purpose of the present invention and its structural and functional characteristics will be described according to the preferred embodiments of the accompanying drawings.

[0047] see Figure 1A , Figure 1B , Figure 1C and Figure 1D , is an exploded schematic diagram, a combined schematic diagram, a cross-sectional schematic diagram and a schematic diagram of the first embodiment of the present invention. Figure 1C A partial schematic diagram of the present invention mainly includes a fan frame 1, a support shaft 2, an oil bearing 3, a rotor set 4, a limiting element 5, a thrust element 6 and a stator set 7:

[0048] The fan frame 1 includes an upper case 11 and a lower case 12. The outer edge of the lower case 12 extends vertically from a side wall 121 and surrounds an air outlet 14. An air inlet 13 is arranged on the upper case 11. The upper case 11 and The combination of the side walls 121 of the lower case 12 jointly define a fan blade area...

Abstract

The present invention provides an anti-pressing fan structure, which includes: a fan frame with an upper shell and a lower shell, the upper shell has an air inlet; a support shaft, one end is inserted on one side of the lower shell, and the other end extending beyond the upper shell; an oil bearing, having a bearing hole and sleeved on the outside of the support shaft; a rotor group, sleeved and combined with the outer edge of the oil bearing; a limiting element, sleeved on the outer edge of the support shaft and Close to the upper end of the oil bearing; a thrust element, sleeved on the outer edge of the support shaft and close to the lower end of the oil bearing; a stator group, arranged on the lower shell and adjacent to the outer edge of the oil bearing and not in contact with the oil bearing bearing contact. With the above structure, the support shaft is used to prevent the fan from stopping or being damaged due to the excessive downward pressure of an external unit above the fan, so as to achieve the purpose of preventing the fan from being pressed.

Description

technical field [0001] The invention relates to the field of fans, in particular to an anti-pressing fan structure. Background technique [0002] Cooling fans are widely assembled in desktop computers, notebook computers, tablet computers and other electronic products to generate heat dissipation, and the current design trend of notebook computers, tablet computers and other products is to take light and thin as the design consideration. In order to comply with the current thin and light trend, the current fan is designed as a thin fan. However, the thin fan is easily pressed by the touch of the panel or the keyboard, causing the fan wheel to be damaged or the flow channel to be deformed so that the air cannot flow out. [0003] Therefore, how to solve the above-mentioned problems and deficiencies is the direction that the inventors of this case and related manufacturers engaged in this industry are eager to study and improve. Contents of the invention [0004] To improv...
