[0045] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] like Figure 1-Figure 10 As shown, this embodiment provides an air outlet structure of a cooling fan, including a shell, an air guide structure and a first driving device.

[0047] An air outlet 3 is provided on the shell.

[0048] The air guide structure is arranged at the air outlet 3, and is provided with an upward humidification outlet 4. Under the action of external force, the air guide structure has a first position in which the humidification outlet 4 is exposed outside the shell, and a second position in which the humidification outlet 4 is accommodated in the shell.

[0049] The first driving device includes a first power device 81 and a first crank 82. The first power device 81 is arranged on the shell and has a first output shaft. One end of the first crank 82 is connected to the first output shaft, and the other end is rotatably connected to the air guide structure, and under the drive of the first output shaft, the air guide structure is driven to switch between the first position and the second position.

[0051] The specific structural forms of the air guide structure can be various. In this embodiment, the air guide structure includes an air guide body 5 and an air outlet grille.

[0052] The bottom of the air guide body 5 is rotatably connected to the shell, and the top extends from the air outlet grille into the air outlet 3. A limiting structure 51 is provided at one end of the top away from the air outlet grille to limit the top of the air guide body 5 from escaping from the air outlet 3.

[0053] The air outlet grille is arranged on the air guide body 5 and has a closed state covering the air outlet 3 and an open state opening the air outlet 3 ; the top of the air outlet grille and the top of the air guide body 5 together form a humidification outlet 4 .

[0054] Specifically, in this embodiment, one end of the first crank 82 away from the first output shaft is rotatably connected to the top of the air guide body 5 .

[0055] In this way, in summer, the air outlet grille can blow cold air to people to make them feel cool, and in winter, the humidification outlet 4 can be used to humidify people to avoid blowing cold mist to people and making them feel cold. At the same time, by providing the limiting structure 51, the air guide structure can be prevented from escaping from the air outlet 3 when the air guide structure is in the first position.

[0056] As a convertible embodiment, the air outlet grille may not be provided, and the cold wind in summer and the wet mist in winter are discharged from the humidification outlet 4.

[0057] In this embodiment, a hinge shaft 52 is provided at the bottom of the air guide body 5 , and a hinge hole 11 is provided on the shell body, and the hinge shaft 52 is inserted into the hinge hole 11 .

[0058] The specific structural forms of the limiting structure 51 can be various. The limiting structure 51 in this embodiment is a hook-shaped structure arranged on the top of the air guide body 5. The hook-shaped structure is stuck to the inner side of the shell when the air guide structure is in the first position.

[0059] In this embodiment, the air guide body 5 includes two triangular plates arranged opposite to each other on both sides of the air outlet grille, a hinge shaft 52 is provided at the bottom of the triangular plate, and a hook structure is provided at one end of the top away from the air outlet grille.

[0060] The air outlet grille includes a plurality of grille units 6 , both ends of which are provided with rotation shafts 61 , and the air guide body 5 is correspondingly provided with mounting holes 53 . The grille units 6 are rotatably connected to the shell through the cooperation between the rotation shafts 61 and the mounting holes 53 .

[0061] Furthermore, the air outlet structure of the cooling fan provided in this embodiment also includes two air guide connecting rods 7 arranged on both sides of the air outlet grille, each air guide connecting rod 7 is provided with multiple drive shafts at intervals along the length direction; the two ends of the grille unit 6 are respectively provided with matching holes, the matching holes are arranged at intervals with the rotating shaft 61, and each grille unit 6 is arranged along the length direction of the air guide connecting rod 7 and is connected with the corresponding drive shaft. In this way, only one grille unit 6 needs to be moved or the air guide connecting rod 7 needs to be moved, and the angle adjustment of all grille units 6 can be achieved through the air guide connecting rod 7, which can facilitate the adjustment of the air outlet angle.

[0062] The air outlet grille can be switched between the closed state and the open state manually or electrically. In this embodiment, one end of the air guide connecting rod 7 is provided with a transmission hole, and the air outlet structure of the cold fan further includes a second driving device, which includes a second power device 91 and a second crank 92.

[0063] The second power device 91 has a second output shaft that outputs rotational power.

[0064] One end of the second crank 92 is connected to the second output shaft, and the other end is cooperatively connected to the transmission hole, and driven by the second output shaft, the wind guide connecting rod 7 is driven to rotate around the rotating shaft 61.

[0065] In this way, the second crank 92 can be driven to rotate by the second power device 91, and then the air guide connecting rod 7 can be driven to rotate around the rotating shaft 61, so that the air outlet angle of the air outlet grille can be automatically adjusted.

[0066] The shell may have various specific structural forms. In this embodiment, the shell includes a front shell 1 , a rear shell and an air outlet frame 2 .

[0067] The front shell 1 is provided with an air outlet 3 .

[0068] The rear shell cooperates with the front shell 1 to form a receiving cavity.

[0069] The air outlet frame 2 is disposed in the accommodating cavity and is fixedly connected to the front shell 1 .

[0070] Furthermore, a slot 21 is provided at the top of the air outlet frame 2, and the top end of the air guide connecting rod 7 is inserted into the slot 21 when the air guide structure is in the second position, and is released from the slot 21 when the air guide structure is in the first position.

[0071] When the surrounding environment is hot, the blowing mode is turned on, the air guide structure is in the second position, and the top end of the air guide connecting rod 7 is clamped in the clamping slot 21, so that the second power device 91 works, driving the second crank 92 to drive the air guide connecting rod 7 to move, opening the grille unit 6, and making the air outlet grille in an open state. The cold air blows directly towards the human body through the air outlet grille, so that the user can quickly feel the coolness.

[0072] When the surrounding environment is dry, the humidification mode is turned on to make the first power device 81 work. The first power device 81 drives the first crank 82 to rotate. The first crank 82 pushes the top of the air guide body 5 to move outward, and the top of the air guide connecting rod 7 is disengaged from the slot 21. The air guide body 5 rotates relative to the shell around the hinge shaft 52 until the hook structure abuts against the inner side of the shell. At this time, the air guide structure is in the first position, the humidification outlet 4 is opened, and the wet mist is discharged from the humidification outlet 4 to avoid blowing towards the human body, thereby increasing the humidity of the surrounding environment and preventing people from feeling cold.

[0073] The first power device 81 and the second power device 91 may have various specific forms. In the present embodiment, the first power device 81 and the second power device 91 are both motors.

[0074] This embodiment also provides a cooling fan, including the above-mentioned air outlet structure of the cooling fan.

[0075] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
