A plane formed by the moving direction of the air guide 79 and the moving direction of the flexible link 73 is perpendicular to the opening direction of the first outlet 71 of the nozzle 7, thereby reducing the overall thickness and the spatial volume of the nozzle 7.

In a preferred embodiment, the flexible linkage 73 and the motor 72 are disposed at a connection portion of the nozzle 7, and when the flexible linkage 73 moves in an extending direction of the nozzle 7, one air guide 79 vertically ascends and the other air guide 79 vertically descends, but not limited thereto.

The specific embodiment of the utility model is as follows:

fig. 7 is a schematic view of a projection area of the fan of the present invention in an air cleaner state. Fig. 8 is a schematic view of the fan of the present invention in a projection area under the fan. Referring to fig. 4, 5, 6, 7, 8, the fan of the present invention includes a body 1 for generating an air flow and a nozzle 7 for spraying the air flow. Wherein the body 1 comprises at least a top cover, a filter 2, an inlet hood 3 providing an air inlet, a fan motor assembly 5 for generating an air flow, a housing 8 providing an air outlet, and a nozzle 7. The first side of the housing 8 is provided with an air inlet 81 and the filter 2 is arranged in the housing 8 at a position corresponding to the inside of the air inlet 81. The filter 2 is arranged upstream of the inlet hood 3, the filter 2 surrounding the inlet hood 3. The air inlet cover 3 is arranged at an air inlet of the fan motor component 5. The fan motor assembly 5 causes an air flow through the body 1 in a first direction, which is the direction of gravity. The nozzle 7 is connected to the air outlet for receiving the air flow from the body 1 and emitting the air flow, which enters the nozzle 7 with the air flow, which is emitted out of the nozzle 7 at least after moving in a second direction opposite to the first direction, which is the anti-gravity direction. The air inlet is provided in an inlet hood 3, which inlet hood 3 is located in the upper part of the body 1 in the direction of gravity. The air outlet is located in the lower part of the second side of the casing 8 of the body 1 in the direction of gravity and the fan-motor assembly 5 is located in the region between the air inlet and the air outlet. The nozzle 7 has at least one outlet duct, the extension direction of which is parallel to the first direction, and the air flow passes through the outlet duct in the second direction. The fan of the utility model adopts an air duct design completely different from the prior art, the air suction direction of the fan motor component 5 is reversed, high air suction is carried out from the upper part of the body part 1, air flow passes through the fan motor component 5 from top to bottom and enters the nozzle 7, and the air flow flows from bottom to top through the nozzle 7.

With continued reference to fig. 6 and 7, when the flexible link 73 moves in the clockwise direction (V1 direction), the left air guide 79 is lifted, and at the same time, the right air guide 79 is lowered. The left air guide 79 is guided by the oblique chute 751, and moves in an outer direction away from the central axis of the fan while rising (the direction of W1, in this embodiment, the plane formed by the direction of V1 and the direction of W1 is perpendicular to the air outlet direction of the nozzle 7), so that the maximum overlapping area between the second outlet projection area 74A of the left air guide 79 and the corresponding first outlet projection area 71A is achieved. At the same time, the right air guide 79 is guided by the inclined chute 751 and moves in the inward direction (direction W1) toward the fan center axis while descending, so that the overlapping area of the second outlet projection area 74A of the right air guide 79 and the corresponding first outlet projection area 71A is maximized, the overlapping area S1 of the projection areas overlaps the first outlet projection area 71A and the second outlet projection area 74A in the air cleaner state, and the first outlet 71 and the second outlet 74 are completely overlapped. Since the total area of the second air outlet, the total area of the first air outlet, and the total area of the effective flow cross section of the nozzle 7 are equal to or greater than the area of the air inlet, the nozzle 7 can discharge the purified air to the outside of the nozzle 7 by not pressurizing the air flow when the fan is in the air purifier state. (equivalent to a state of forming a 'no wind' effect), purified air is preferentially provided for a user facing the fan, and the personal experience of the user is improved.

Referring to fig. 6 and 8, when the flexible link 73 moves in the counterclockwise direction (V2 direction), the left air guide 79 is lowered, and at the same time, the right air guide 79 is raised. The left air guide 79 is guided by the oblique chute 751, and moves toward the inner side of the central axis of the fan while moving downward (in the direction of W2, in this embodiment, the plane formed by the direction of V2 and the direction of W2 is perpendicular to the air outlet direction of the nozzle 7), so that the displacement between the left second air outlet 74 and the first air outlet 71 is realized, and the overlapping area between the second air outlet projection area 74A of the left air guide 79 and the corresponding first air outlet projection area 71A is greatly reduced. Meanwhile, the right air guide 79 is guided by the inclined chute 751, and moves in an outer direction (direction W2) away from the central axis of the fan while rising, so that the right second outlet 74 and the first outlet 71 are displaced, and the overlapping area between the second outlet projection area 74A of the right air guide 79 and the corresponding first outlet projection area 71A is also greatly reduced. Since the overlap S2 of the projected areas in the fan state is significantly smaller than the first outlet projected area 71A or the second outlet projected area 74A, the total area of the effective flow cross section of the nozzle 7 in this case is significantly smaller than the area of the air inlet, and the nozzle 7 emits the air flow in the fan state. The nozzle 7 can emit a high-speed air stream to the outside of the nozzle 7 in a state where a "blowing" effect is formed by pressurizing the air stream.

In addition, the utility model overlaps the position layout of the fan motor component 5 and the position layout of the nozzle 7 in the first direction, further reduces the whole height, and fully utilizes the idle space in the center of the nozzle 7. Moreover, on the premise of equal height, the utility model can realize a larger nozzle 7 and strengthen the air supply capability. The nozzle 7 and the fan motor assembly 5 in the present invention may be arranged in parallel in the first direction (or the second direction), and the nozzle 7 and the fan motor assembly 5 may at least partially overlap each other based on the projection of the same vertical plane. This allows the outlet 71 of the nozzle 7 to be disposed at the same level as the fan motor assembly 5, even at a level lower than the level of the fan motor assembly 5. According to the utility model, through the improvement of the air channel, the long-distance air flow stroke of the air flow passing through the fan motor assembly and the nozzle in the single direction in the prior art is divided into at least two short-distance air flow strokes in opposite directions, and the two short-distance air flow strokes can be mutually parallel, so that the industrial technical barrier that the fan motor assembly and the nozzle must be sequentially arranged in the height direction is broken through, the overall height of the fan can be greatly reduced, the gravity center of a product is also reduced, and the stability of the standing posture of the product is improved. And the air inlet that is located the top position can not inhale the dust on ground when breathing in, has reduced the use load of filter screen, need not to change the filter screen frequently, has reduced the use cost of bladeless fan filter screen greatly.

In summary, the present invention is directed to a fan, which can change the air channel state in the fan, so that the fan can be switched between a pure air purifier state and a fan state with an air purifier, thereby enlarging the use scene and improving the user experience.

The foregoing is a more detailed description of the utility model in connection with specific preferred embodiments and it is not intended that the utility model be limited to these specific details. For those skilled in the art to which the utility model pertains, numerous simple deductions or substitutions may be made without departing from the spirit of the utility model, which shall be deemed to belong to the scope of the utility model.
