The utility model will be described in detail below with reference to the accompanying drawings. As shown in FIG. 1 , a cooling and heating fan structure of the utility model includes: a housing 110 , an air outlet structure 120 , a fan module 130 and a fixing structure 140 . The fan module 130 is provided with a motor 131, the air outlet structure 120 is arranged at one end of the casing 110, the fan module 130 and the fixing structure 140 are arranged inside the casing 110, and the motor 131 provided in the fan module 130 is electrically connected to the fan assembly 160. The fan blade 132 is connected to drive the fan module 130 to rotate, and the fixing structure 140 is used to fix the fan module 130 and/or the motor 131 to the casing 110 . The air outlet structure 120 is provided with a plurality of trumpet-shaped through holes 150 . Each trumpet-shaped through hole 150 has a large opening 151 and a small opening 152 , and the large openings 151 of the plurality of trumpet-shaped through holes 150 face the same direction.

As shown in Figure 2, the through hole 150 has a large mouth end 151 and a small mouth end 152, and the diameter of the large mouth end 151 is 3-6 times of the diameter of the small mouth end 152, preferably, the diameter of the large mouth end 151 is 4 times of the diameter of the small mouth end 152 times. The inner surface of the through hole 150 is a smooth curved surface, and the diameter gradually decreases from the large opening end 151 to the small opening end 152 . In this embodiment, the through hole 150 is a truncated cone structure.

The large ends 151 of the trumpet-shaped through-holes 150 face toward the end close to the fan assembly 160 , and the fan module 130 includes two or more fan assemblies 160 .

The first embodiment of the present utility model is: as shown in Figure 3, the air outlet structure 120 is a circular cover plate, and a plurality of through holes 150 are evenly arranged on the air outlet structure 120 at intervals of a certain distance; all the large openings of the through holes 150 End 151 is located close to fan assembly 160 and all small ports 152 are located away from fan assembly 160 .

It can be understood that, as shown in FIG. 4 , multiple sets of fan assemblies 160 may be provided in the fan module 130 , that is, multiple sets of motors 131 and corresponding fan assemblies 160 . Of course, the same motor 131 can also drive multiple fan assemblies 160 .

When working, when the fan blade 132 in the fan module 130 can continue to rotate under the drive of the motor 131, the rotation of the fan blade 132 drives the air in the casing 110 to flow faster, and then the air flow flows in from the large end 151 of the through hole 150, Flow out from the small mouth end 152 of the through hole 150 . As the high-speed air flow passes through the through hole 150 , the diameter of the through hole 150 gradually becomes smaller, and the inner wall of the through hole acts on the air flow, thereby reducing the temperature.

It can be understood that when the natural wind is strong enough, the motor 131 does not need to be turned on. At this time, the larger natural wind can drive the fan blade 132 of the fan module 130 to continue to rotate. The rotation of the housing 110 drives the air in the housing 110 to flow faster, and then the air flows in from the large opening 151 of the through hole 150 and flows out from the small opening 152 of the through hole 150 . As the high-speed air flow passes through the through hole 150 , the diameter of the through hole 150 gradually becomes smaller, and the inner wall of the through hole acts on the air flow, thereby reducing the temperature.

The inner surface of the through hole 150 is a smooth curved surface, which reduces the resistance of the side wall to the wind flow, and greatly reduces the noise caused by the rapid wind flow colliding with the side wall, thereby reducing noise pollution.

The second embodiment of the present invention is: as shown in FIG. 4 , the fan module 230 is provided with two motors 231 , two sets of fan assemblies 260 and corresponding fan blades 232 . Its working principle is the same as the working principle of a single motor 131 and a single fan assembly 132 , which will not be repeated here.

The large ends 352 of the plurality of trumpet-shaped through holes 350 face toward the end away from the fan module 330 , and the fan module 330 includes two or more fan assemblies 360 .

The third embodiment of the present utility model is as follows: as shown in FIG. 5 , all the small openings 351 of the through holes 350 provided on the air outlet structure 320 are arranged close to the fan assembly 360 , and all the large openings 352 are arranged away from the fan assembly 360 .

When working, when the fan blade 342 in the fan module 330 can continue to rotate under the drive of the motor 341, the rotation of the fan blade 342 drives the air in the casing 310 to flow at an accelerated rate, and then the airflow flows in from the small opening 351 of the through hole 350, from The wide mouth end 352 of the through hole 350 flows out. Since the wind flow enters the channel and is diffused, the speed of the wind flow is greatly reduced, so that the cold air is greatly weakened, thereby producing a heating effect.

It can be understood that a hook is provided on the outer surface of the housing 310 to hang it on the equipment or the wall.

The outer casing 310 provided on the outer periphery of the fan module 330 is cylindrical or regular polygonal in shape. Preferably, the outer outer casing 310 of the fan module 330 is cylindrical in shape. The shell 310 is cylindrical, which is not only beautiful, but also occupies less space.

The inner surface of the through hole 350 is a smooth curved surface, which can reduce the noise generated by the airflow colliding with the inner surface of the through hole 350 .

The air outlet structure 320 is a cover plate, and a plurality of trumpet-shaped through holes 350 pass through the cover plate, thereby allowing air to enter from one end 351 of the through holes 350 and flow out from the other end 352 of the through holes 350 .

It can be understood that the cooling and heating fan structure of the present utility model can be used alone, or it can be attached to various devices for cooperative use.

The beneficial effects of the utility model lie in the following aspects: firstly, the fan structure disclosed in the utility model is a multifunctional fan, which can not only cool down but also heat up; Third, the utility model does not need to add ice cubes or refrigerants, does not indirectly generate power consumption, and does not dissipate heat into the air to protect the environment; fourth, the special curved surface design reduces noise pollution; finally , which is simple in structure, easy to manufacture, and low in cost.

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modifications or equivalent replacements of the technical solutions without departing from the purpose and scope of the technical solutions of the utility model shall be covered by the claims of the utility model.
