Description

Technical Field

[0001] This invention relates to the field of fans, and more specifically to a cooling fan. Background Technology

[0002] A fan is a device used to generate airflow and cool down in hot weather. An electric fan is a device that uses electricity to drive airflow. When the fan inside is powered on, it rotates, converting mechanical energy into wind energy, which is then transformed into natural wind to achieve a cooling effect.

[0003] However, in the hot and humid summer, the air temperature is also very high, which causes the air blown out by the fan to be hot as well, resulting in a poor overall cooling effect and making it difficult to provide a comfortable cooling experience.

[0004] In addition, brushless motors currently have advantages over brushed motors, such as lower noise, smoother operation, less heat generation, and longer lifespan, making them more suitable for the usage environment of household appliances. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a cooling fan that generates a cold source by placing cold water or a combination of cold water and ice in a water tank, and at the same time, combines a hollow plate with good thermal conductivity to achieve the effect of absorbing heat and cooling the air, so that the fan can blow a comfortable and cool breeze even in hot and humid environments.

[0006] Technical solution

[0007] A cooling fan includes a base plate, a mounting bracket fixedly mounted on the base plate, a brushless motor fixedly mounted on the mounting bracket, a fan poweredly connected to the brushless motor, a water tank fixedly mounted on the top of the mounting bracket, a circulation mechanism for cooling the air supplied to the fan provided on the lower side of the water tank, and an auxiliary mechanism for heat preservation for assisting the circulation mechanism on the base plate.

[0008] Furthermore, the circulation mechanism includes two return pipes fixedly connected to the upper side of the water tank and two outlet pipes fixedly connected to the lower side of the water tank. Several hollow plates are connected between the two outlet pipes and the two return pipes. An upper insulation layer is provided on the upper surface of the uppermost hollow plate, and a lower insulation layer is provided on the lower surface of the lowermost hollow plate. Side insulation plates are also provided at the front and rear ends of the hollow plates.

[0009] Furthermore, the auxiliary mechanism includes an electric telescopic rod fixed to the base plate, with a crossbar fixedly connected to the upper end of the electric telescopic rod, and auxiliary insulation boards fixedly connected to the left and right ends of the crossbar, respectively.

[0010] Furthermore, the return water pipe, the outlet water pipe, and the water tank are all made of heat-insulating materials, and the hollow plate is made of heat-conducting materials.

[0011] Furthermore, a water outlet is provided at the lowest end of the water outlet pipe.

[0012] Furthermore, a water inlet is provided on the upper side of the water tank.

[0013] Beneficial effects

[0014] Compared with existing technologies, this invention has the following advantages: It generates a cold source by placing cold water or a combination of cold water and ice in the water tank, while simultaneously using a hollow plate with excellent thermal conductivity to absorb and cool the air. This allows the fan to blow a comfortable, cool breeze even in hot, humid environments. The overall design uses heat-insulating materials or incorporates a heat-insulating layer, significantly reducing unnecessary heat transfer, improving cold source utilization, and extending usage time. In a home environment, ice or cold water are readily available materials, making the overall design very convenient. It is ideal for outdoor use and can also be used indoors as an alternative to air conditioning, saving energy. The use of a brushless motor results in lower noise, smoother operation, less heat generation, and a longer lifespan compared to brushed motors. The inclusion of an auxiliary insulation plate ensures that the cold source does not overheat even during short periods of non-use. Attached Figure Description

[0020] To better illustrate the content of this invention, the following description is provided in conjunction with the accompanying drawings and examples:

[0021] have Figures 1-3As shown, the present invention discloses a cooling fan, including a base plate 1, a mounting bracket 3 fixedly mounted on the base plate 1, a brushless motor 7 fixedly mounted on the mounting bracket 3, a fan 6 poweredly connected to the brushless motor 7, a water tank 9 fixedly mounted on the top of the mounting bracket 3, a circulation mechanism 901 for cooling the air supplied to the fan 6 provided on the lower side of the water tank 9, and an auxiliary mechanism 902 for assisting the circulation mechanism 901 in heat preservation on the base plate 1.

[0022] Furthermore, the circulation mechanism 901 includes two return water pipes 12 fixedly connected to the upper side of the water tank 9 and two outlet water pipes 15 fixedly connected to the lower side of the water tank 9. Several hollow plates 11 are connected between the two outlet water pipes 15 and the two return water pipes 12. An upper insulation layer 16 is provided on the upper surface of the uppermost hollow plate 11, and a lower insulation layer 13 is provided on the lower surface of the lowermost hollow plate 11. Side insulation plates 10 are also provided at the front and rear ends of the hollow plate 11.

[0023] Furthermore, the auxiliary mechanism 902 includes an electric telescopic rod 2 fixedly mounted on the base plate 1, with a crossbar 4 fixedly connected to the upper end of the electric telescopic rod 2, and auxiliary insulation boards 5 fixedly connected to the left and right ends of the crossbar 4, respectively.

[0024] Furthermore, the return water pipe 12, the outlet water pipe 15, and the water tank 9 are all made of heat-insulating materials, and the hollow plate 11 is made of heat-conducting materials.

[0025] Furthermore, the lowest end of the water outlet pipe 15 is provided with a water outlet 14.

[0026] Furthermore, a water inlet 8 is provided on the upper side of the water tank 9.

[0027] Specifically, when needed, cold water is added into the water tank 9 through the inlet 8, and ice cubes can be added into the water tank 9 at the same time for cooling and heat preservation.

[0028] After placing the ice, activate the electric telescopic rod 2 and raise the auxiliary insulation plate 5 until the left and right ends of the hollow plate 11 are sealed, reducing the gap between the hollow plates 11 and the airflow to the outside, thus reducing heat transfer.

[0029] At this point, you can wait for the ice to slowly cool the water inside water tank 9.

[0030] When temporarily leaving or when the air conditioning is not needed, you can also choose to reduce heat transfer by using the auxiliary insulation board 5;

[0031] Then the brushless motor 7 is started, and the fan 6 rotates. The air on the right side of the brushless motor 7 will be blown to the left through the gap between the hollow plates 11 by the fan 6.

[0032] When the air passes through the gaps between the hollow plates 11, it will be cooled by the hollow plates 11 and the cold water inside, thus achieving the effect of blowing cold air, which can be achieved by blowing air through a fan.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the technical solutions of the present invention have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
