[0038] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] 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.

[0040] like Figure 1-Figure 10 As shown, this embodiment provides an air outlet structure of a cooling fan, including a shell and an air guide structure.

[0041] An air outlet 3 is provided on the shell.

[0042] 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 where the humidification outlet 4 is exposed outside the shell, and a second position where the humidification outlet 4 is accommodated in the shell.

[0043] By setting the humidification outlet 4 upward, when it is necessary to humidify the room in winter, it is only necessary to apply external force to the air guide structure to make the air guide structure in the first position, so that the atomized water will be discharged upward from the humidification outlet 4, which can avoid blowing towards people during humidification, thereby increasing the humidity of the surrounding environment and avoiding people from feeling cold; when it is not necessary to humidify the room, it is only necessary to make the air guide structure in the second position.

[0044] In this embodiment, the wind guide structure is switched between the first position and the second position by manually applying an external force to the wind guide structure. In other embodiments, a motor may be provided to drive the wind guide structure to switch between the first position and the second position.

[0045] 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.

[0046] 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.

[0047] 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 .

[0048] 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.

[0049] 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.

[0050] Specifically, 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 .

[0051] 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.

[0052] 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.

[0053] The specific structural form of the air outlet grille is not limited. In the present embodiment, the air outlet grille includes a plurality of grille units 6. Rotation shafts 61 are respectively provided at both ends of the grille units 6. Mounting holes 53 are correspondingly provided on the air guide body 5. The grille units 6 are rotatably connected to the shell through the cooperation of the rotation shafts 61 and the mounting holes 53.

[0054] Furthermore, the air outlet structure of the cooling fan provided in this embodiment further 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 a plurality of drive shafts 71 at intervals along the length direction; both ends of the grille unit 6 are 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 matched and connected with the corresponding drive shaft 71. In this way, only one grille unit 6 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.

[0055] 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 .

[0056] An air outlet 3 is provided on the front shell 1 .

[0057] The rear shell cooperates with the front shell 1 to form a receiving cavity.

[0058] The air outlet frame 2 is disposed in the accommodating cavity and is fixedly connected to the front shell 1 .

[0059] 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.

[0060] 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 stuck in the card slot 21. The user can manually open the grille unit 6 to put 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 cool.

[0061] When the surrounding environment is dry, the humidification mode is turned on, and the user manually pulls the air guide body 5, and the top end of the air guide connecting rod 7 disengages from the slot 21, and 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.

[0062] This embodiment also provides a cooling fan, including the above-mentioned air outlet structure of the cooling fan.

[0063] 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.
