Leafless electric fan is easy to use?

In recent years, in the continuous invasion of air conditioners, the sales volume of electric fans has gradually declined. At this time, in order to attract more consumers to buy, the hearts of those lost consumers are recovered. The electric fan also undergoes a round of reforms. At this time, the leafless electric fan appeared in front of the people. For a leafless electric fan, people will think it is more novel, what are the different places?

Is the leafless electric fan easy to use?

Is the leafless fan good? The leafless fan is also called the air multiplier. It produces a natural and continuous cool breeze. Since there are no blades, it will not cover the dust or hurt the curious children's fingers when used. What's even more amazing is that its shape is strange, and its appearance is both streamlined and refreshing. Its inspiration comes from the air blade hand dryer. The principle of the hand dryer is to force the air to "brush" the water on the hand through a small mouth. The air multiplier blows the air out of a slit that is 1.3 mm wide and rotates around the ring.

Why is this saying? From the energy point of view, the air inlet and outlet of the bladeless fan increase the resistance of the wind flow compared with the conventional fan, and the conversion efficiency is inevitably not as high as that of the conventional fan, that is to say, The same power consumption of the leafless fan will be higher than the traditional fan.

What are its advantages? The fanless fan has a variable frequency wind speed adjustment device at the same time, which is convenient for the user to adjust the wind speed according to the actual situation, the air volume is evenly increased, the voltage is not impacted, and the energy consumption is low, which is half of the energy consumption of the ordinary fan. At the same time, the airflow will also move the air in the ring forward by the viscous force. The result of the superposition of the two effects can theoretically make the actual amount of air blown a full 15 times the amount of air flowing through the pedestal!

Leafless electric fan selection tips

One of the tips for the leafless electric fan: the appearance color of the leafless fan, it is best to choose white, it must be white for injection molding, not white for injection. When buying, you can observe whether the color inside and outside the product is consistent. To judge. Because white products must be produced with raw materials, and sprayed products can be produced with second-hand materials (waste), and then sprayed with color to cover the inferior quality of plastic products. Most of the more than 100 leafless fans on the market are sprayed with color, so you can check it out. This method can also be used to purchase other pigment products. Plastic materials are about twice as expensive as second-hand materials.

The second choice of bladeless electric fan: check whether there is black powder on the edge of the wind gap. Be sure to check if it is black. If there is black powder on the edge, the manufacturer has used a carbon brush motor to produce no leaf. The fan, while the carbon brush bladeless fan will wear the carbon brush continuously during operation, and the black powder will be blown out.

The third choice of bladeless fan: adjust the wind speed of the leafless fan, close the ear to the air inlet, listen carefully to the sound, if there is obvious motor sound (high frequency sound), the driver board used by the fan is not a sine wave, and It is square wave, the quality is not up to standard, and the longer it takes, the louder the sound will be.

In people's subconscious, when it comes to electric fans, people will think of a fan with leaves. However, in recent years, with the emergence of leafless electric fans, there has been a good improvement in wind speed. Therefore, since the birth of the leafless electric fan, it has been receiving widespread attention and giving us a life belt. Come for more wonderful experiences.
