[0049] figure 1 It is a perspective view of the fan of the present invention from a first perspective. figure 2 It is a perspective view of the fan of the present invention from a second perspective. image 3 It is a side sectional view of the fan of the present invention. like Figures 1 to 3 As shown, the fan of the present invention includes: an integral part 1 , a support member 41 , a base 42 and a nozzle 7 . The body 1 includes an air inlet, an air outlet and a fan motor assembly 5 . The fan motor assembly 5 includes a horizontal motor for generating air flow through the body 1 . The supporter 41 supports the body portion 1 . The nozzle 7 is connected to the body 1 based on the air outlet direction of the horizontal motor, and is used to receive the air flow from the body, spread it along the inside of the nozzle 7 to each air outlet 71 and spray. The base 42 supports the supporter 41 . The support member 41 is a support rod, and the extension direction of the support rod is perpendicular to the rotation axis of the horizontal motor. The opening direction of the air outlet 71 is parallel to the rotation axis of the horizontal motor. The casing of the body part 1 is a horizontally arranged cylindrical casing, the cylindrical casing is sleeved with a horizontal motor, and the casing is provided with a plurality of air inlet holes 11 . The cylindrical shell includes opposite first ends and second ends, and the first end of the cylindrical shell communicates with an air guide hood 6, which guides the air flow to the bottom 7A of the nozzle 7, and the air flow along the inside of the annular nozzle. The annular air passage moves toward the top 7B of the nozzle 7 in the direction of anti-gravity, and is sequentially distributed to each air outlet 71 and then fired separately. 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.
[0053] The air dividing wall 62 is embedded within the range of the inner pipeline of the nozzle 7 and is connected behind the first drainage slope 61 . The wind dividing wall 62 is configured to be vertically arranged, and the left and right sides of the wind dividing wall 62 are respectively formed with arc-shaped second drainage slopes 63 and third drainage slopes 64 , extending arcuately to the left and right sides. The air distribution wall 62 divides the air flow introduced into the first drainage slope 61 into a first air branch flow and a second air branch flow from left to right. Among them, the first air branch enters the inner pipeline on the left side of the nozzle 7 to the left, moves to the top 7B of the nozzle 7 in a clockwise direction (clockwise upward), and then sprays after reaching each air outlet 71 on the left side of the nozzle 7; similarly, The second air branch enters the inner pipeline on the right side of the nozzle 7 to the right, moves to the top 7B of the nozzle 7 in the counterclockwise direction (counterclockwise upward), and then sprays after reaching each air outlet 71 on the right side of the nozzle 7, but this is not the case. limit.
[0054]In this embodiment, the first diversion slope 61 , the wind dividing wall 62 , the second diversion slope 63 , and the third diversion slope 64 are realized by the surfaces of different parts of the same diversion structure, but not limited thereto. In the present invention, the air guide hood 6 and the nozzles 7 are used to divide the linear air flow and guide it to the air outlets 71 of different nozzles 7 smoothly, thereby reducing noise and avoiding the reduction of wind pressure when the air flow direction is adjusted. Small, the air volume of the air flow can be maintained, so that the air volume of the air flow emitted by the nozzle 71 is basically close to the air volume of the air flow generated by the fan motor assembly 5, and the loss of the internal pipeline to the wind force can be minimized.
[0055] Figure 5 It is a schematic diagram of the distribution of the air outlet of the nozzle of the fan of the present invention. like Figure 5 As shown, the flow cross-sectional area of each air outlet 71 gradually increases as the position of the nozzle 7 from the bottom 7A to the top 7B changes. In this embodiment, by optimizing and adjusting the opening areas of the air outlets at different positions, the air volume of each air outlet 71 at different heights is basically equal, but it is not limited thereto. The air outlet 71 can also be a circular opening, an oval opening, etc., which is not limited thereto.
[0056] In a preferred example, the air outlet 71 is a rectangular opening. As the air outlet 71 rises from the bottom 7A to the top 7B of the nozzle 7 based on the position of the nozzle 7 , the length of the long side of the rectangular opening gradually increases, but this is not the case. limit.
[0057] In a preferred example, the air outlet 71 is a rectangular opening. As the air outlet 71 rises from the bottom 7A to the top 7B of the nozzle 7 based on the position of the nozzle 7 , the length of the short side of the rectangular opening gradually increases, but this is not the case. limit.
