Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0049] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] As Figures 1-11 shown, this embodiment provides an air outlet structure of a cold fan, including a housing, an air guide structure and a first driving device.

[0051] An air outlet 3 is provided on the housing.

[0052] The air guiding structure is arranged at the air outlet 3. The air guiding structure is provided with an upward humidifying discharge outlet 4, and under the action of an external force, it has a first position where the humidifying discharge outlet 4 is exposed outside the housing and a second position where the humidifying discharge outlet 4 is received in the housing.

[0053] The first driving device is connected to the air guiding structure and drives the air guiding structure to switch between the first position and the second position.

[0054] By providing the upward humidifying discharge outlet 4, when it is necessary to humidify the indoor environment in winter, only need to drive the air guiding structure through the first driving device to make the air guiding structure in the first position. In this way, the atomized water will be discharged upward from the humidifying discharge outlet 4, which can avoid blowing directly at people during humidification, increase the humidity of the surrounding environment, and avoid making people feel cold. When it is not necessary to humidify the indoor environment, only need to drive the air guiding structure to switch to the second position through the first driving device.

[0055] The specific structural form of the air guiding structure can be various. In this embodiment, the air guiding structure includes an air guiding body 5 and an air outlet grille.

[0056] The bottom of the air guiding body 5 is rotatably connected to the housing, the top extends into the air outlet 3 from the air outlet grille, and a limiting structure 51 for limiting the top of the air guiding body 5 from disengaging from the air outlet 3 is provided at one end of the top away from the air outlet grille.

[0057] The air outlet grille is arranged on the air guiding body 5 and has a closed state of covering the air outlet 3 and an open state of opening the air outlet 3; the top of the air outlet grille and the top of the air guiding body 5 jointly form the humidifying discharge outlet 4.

[0058] In this way, it can blow cold air at people through the air outlet grille in summer to make people feel cool, and can also humidify through the humidifying discharge outlet 4 in winter to avoid making people feel cold due to blowing cold mist directly at people. At the same time, by providing the limiting structure 51, it can prevent the air guiding structure from disengaging from the air outlet 3 when the air guiding structure is in the first position.

[0059] As a variable implementation manner, the air outlet grille can also be not provided, and the cold air in summer and the wet mist in winter are both discharged from the humidifying discharge outlet 4.

[0060] The specific structural form of the first driving device can be various. In this embodiment, the first driving device includes a first power device 81, a gear 82 and a strip hole 83.

[0061] The first power device 81 is arranged on the housing and has a first output shaft for outputting rotational power.

[0063] The strip-shaped hole 83 is disposed on the top of one of the air guide bodies 5 , and a rack 831 meshing with the gear 82 is disposed on the hole wall of the strip-shaped hole 83 .

[0064] 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 .

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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 crank 92.

[0070] The second power device 91 has a second output shaft that outputs rotational power.

[0071] One end of the 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 to drive the air guide connecting rod 7 to rotate around the rotating shaft 61.

[0072] In this way, the 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.

[0073] There can be various specific structural forms of the housing. In this embodiment, the housing includes a front shell 1, a rear shell, and an air outlet frame 2.

[0074] An air outlet 3 is provided on the front shell 1.

[0075] The rear shell cooperates with the front shell 1 to form a receiving cavity.

[0076] The air outlet frame 2 is disposed in the receiving cavity and fixedly connected to the front shell 1.

[0077] Further, a card slot 21 is provided at the top of the air outlet frame 2. The top end of the air guide link 7 is clamped in the card slot 21 when the air guide structure is in the second position, and disengages from the card slot 21 when the air guide structure is in the first position.

[0078] When the surrounding environment is hot, the blowing mode is turned on. The air guide structure is in the second position, and at the same time, the top end of the air guide link 7 is clamped in the card slot 21, causing the second power device 91 to work, driving the crank 92 to drive the air guide link 7 to move, opening the grille unit 6, making the air outlet grille in an open state, and the cold air blows directly at the human body through the air outlet grille, enabling the user to quickly feel cool.

[0079] When the surrounding environment is dry, the humidifying mode is turned on, causing the first power device 81 to work. The first power device 81 drives the gear 82 to rotate. The gear 82 meshes with the rack 831 on the air guide body 5, thereby pushing the top of the air guide body 5 to move outward. The top end of the air guide link 7 disengages from the card slot 21, and the air guide body 5 rotates relative to the housing around the hinge shaft 52 until the hook-shaped structure abuts against the inner side of the housing. At this time, the air guide structure is in the first position, and the humidifying discharge port 4 is opened, and the wet mist is discharged from the humidifying discharge port 4, avoiding blowing at the human body, so that both the humidity of the surrounding environment can be increased and the feeling of cold can be avoided.

[0080] The specific forms of the first power device 81 and the second power device 91 can be various. In this embodiment, both the first power device 81 and the second power device 91 are motors.

[0081] This embodiment also provides a cold fan, including the air outlet structure of the above-mentioned cold fan.

[0082] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
