Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Referring to fig. 1, a schematic structural diagram of a cooling fan 100 according to an embodiment of the present invention is shown. The refrigeration fan 100 comprises, for example, a first refrigeration assembly comprising, for example, a first drip tray 10, a first humidifying element 20 and a first patting element 30. Specifically, the first water pan 10 is provided with a first water receiving area 12; the first humidifying part 20 is arranged on the first water receiving tray 10 and corresponds to the position of the first water receiving area 12, and the first beating part 30 is arranged on one side of the first humidifying part 20 and corresponds to the position of the first water receiving area 12.

Specifically, when the first water receiving area 12 is filled with water, the first beating member 30 is used for beating the water in the first water receiving area 12 onto the first humidifying member 20.

In a specific embodiment, the first beating member 30 may be a beating wheel, the number of the first humidifying members 20 is two, the first beating member 30 is sandwiched between the two first humidifying members 20, and the water is injected into the first water receiving tray 10, so that the water level at least partially covers the beating wheel, and thus, during the beating process of the beating wheel rotating, the water can be splashed onto the first humidifying members 20 on both sides, and thus, the ambient temperature where the refrigerating fan 100 is placed is lower than the ambient temperature of other areas in the room by increasing the evaporation area of the water, so that a user can feel cool when the user is in the vicinity of the refrigerating fan 100.

Preferably, the refrigerating fan 100 includes, for example, a driving assembly 40 and a heat sink 50. Drive assembly 40 is configured to be drivingly connected to first beater element 30, and heat sink 50 is also drivingly connected to drive assembly 40; wherein, the heat sink 50 is disposed on a side of the first humidifying element 20 away from the first beating element 30.

With reference to the foregoing embodiments, in another embodiment, the heat dissipating element 50 is, for example, a centrifugal wind wheel, and the driving assembly 40 is configured to drive the centrifugal wind wheel to rotate, so that, for example, the centrifugal wind wheel rotates clockwise by adjusting the driving assembly 40, so as to form an air outlet side 2 and an air suction side 1, specifically, the air suction side 1 corresponds to a position of the first cooling assembly, and the air outlet side 2 corresponds to a side of the centrifugal wind wheel away from the first cooling assembly. Therefore, in the rotating process of the centrifugal wind wheel, wind passes through the first humidifying part 20, on one hand, evaporation of water on the surface of the first humidifying part 20 is accelerated, so that heat exchange between the refrigerating fan 100 and an indoor environment is improved, and particularly, in a hot environment, the wind outlet side 2 can be in the direction of a human body, so that the comfort of the human body is improved; on the other hand, due to the blocking effect of the first humidifying part 20, the water mist formed by beating the first beating part 30 cannot be absorbed by the centrifugal wind wheel and is brought out from the air outlet side 2, and the phenomenon that the water mist is mixed with particle impurities such as dust and the like and is absorbed by a human body along with formed low-temperature cold air, so that lung diseases and the like are caused is avoided.

Preferably, the drive assembly 40 comprises, for example, a two-shaft motor; the double-shaft motor is provided with a first rotating shaft 41 and a second rotating shaft 42; the first rotating shaft 41 is used for being connected with the first beating member 30 in a matching manner, and further drives the first beating member 30 to rotate; the second rotating shaft 42 is used for being connected to the heat sink 50 in a matching manner, so as to drive the heat sink 50 to rotate. For example, the first rotating shaft 41 and the second rotating shaft 42 may be distributed in the same straight line, at this time, the paddling wheel and the centrifugal wind wheel are also coaxially disposed, the dual-shaft motor is started, the first paddling piece 30 and the heat dissipation piece 50 may be driven to rotate at the same time, because the paddling wheel and the centrifugal wind wheel are coaxially disposed, it is avoided that the paddling wheel and the centrifugal wind wheel are eccentrically disposed, and the dual-shaft motor is in an operation process, so that the refrigeration fan 100 is in an unstable state such as shaking, and similarly, the space occupied by the rotation operation of the paddling wheel and the centrifugal wind wheel is also reduced to a certain extent, so that the overall structure is more compact, for example, when the refrigeration fan 100 needs to be sleeved with the shell, the size of the refrigerator may be selected according to the operation track of the paddling wheel and the centrifugal wind wheel, so as to reduce the cost.
