The second end of the cylindrical shell is provided with a removable cover. The present invention provides a bladeless fan mainly used in the use scene of a vertical fan, which completely replaces the traditional vertical fan, expands the use scene and improves the user experience.
[0050] In a preferred example, the support rod is a liftable support tube assembly, and the support tube assembly includes an inner tube and an outer tube that are axially moved and limited relative to each other, so that the vertical height of the fan outlet air can be adjusted freely.
[0051] Figure 4 It is a schematic diagram of the movement direction of the air flow of the fan of the present invention in the air guide hood and the nozzle. refer to image 3 and 4 As shown, the nozzle 7 is a hollow annular nozzle, and the side of the annular nozzle facing away from the body 1 is distributed with several air outlets 71 along the extending direction of the inner cavity of the annular nozzle. In a preferred example, as the position of the inner pipeline of the nozzle 7 changes from the bottom 7A to the top 7B of the nozzle 7, the flow cross-sectional area gradually decreases, so as to achieve the effect of remote pressure increase, but not limited to this.
[0052] The wind deflector 6 in this embodiment at least includes: a first drainage slope 61 , a wind dividing wall 62 , a second drainage slope 63 and a third drainage slope 64 . Wherein, the first drainage slope 61 is a slope surface, which guides the air flow generated by the fan motor assembly 5 to be deflected downward by 70° to 85° from the horizontal direction (preferably guide the air flow to be deflected downward by 80° from the horizontal direction). The outlet direction of the motor and the movement direction of the air flow in the inner cavity of the nozzle 7 are perpendicular to each other, but not limited to this.
