Say "subversive" Zuvi original solar wireless hair dryer, is it worth starting with?

This time I took Zuvi's original solar wireless hair dryer. In recent years, Dyson is the only "high-end machine" in the hair dryer market. This time, China brand has produced a black technology hair dryer, which is completely innovative in principle. Tell me about this product.

In the past 100 years, hair dryers were all based on the principle of thermal convection: heating air through resistance wires, blowing hot air to the hair and transferring heat to the hair. In this process, nearly 80% of the heat heats your scalp and the surrounding air. This is also the reason why it is easy to sweat or feel dry when blowing in summer.

The principle is very simple, but no one has done it, which shows that this thing is actually not simple. How to optimize efficiency, how to achieve appropriate energy density, and how to consider battery drive all require many innovations in engineering technology.

For wireless, someone gave such a data.

"Good hair dryers are all over one kilowatt. Suppose a 1 kW hair dryer blows your hair for 20 minutes. It's about 0.34 kwh. It is roughly equivalent to the power of 80,000 mAh charging treasure. It takes about 20 minutes for a man and a woman to use it once. You need four 20,000 charging treasures. How big is it? Regardless of the size, what about charging? It takes five minutes to charge for eight hours. "

This shows that the traditional heat convection method can't solve the problem of wireless hair dryer at all. Therefore, it is basically more reliable to use the new technology of "light energy" to realize wireless, with battery life of 13-27 minutes and 19 minutes to charge 90% electricity.

Let me talk about hair care

Hair care, in addition to shampoo, conditioner, hair mask, hair dryer plays a vital role. The function of many expensive hair dryers on the market is not caviar maintenance, but 20 million negative ions, or Japanese gold nano collagen or something.

Why do you emphasize the hair care function after drying?

First, hair is becoming more and more important.

Second, because the technical principle of all hair dryers on the market now is high-temperature air baking, this high temperature is the chief culprit of hair injury.

Hair has a healthy water content standard, that is, at relative humidity, the water content in hair is 15%, which is a healthy state. Blowing hair at high temperature not only evaporates the water outside the hair, but also takes away the water inside the hair. Too much heat can also make hair overheat and lose too much water. Too much water loss will lead to more prone to static electricity, resulting in dryness, static electricity, easy to break and other problems, resulting in short hair and unsmooth hair. Long-term use of this method of hair drying is very harmful to hair. High temperature will change the structure of keratin and cause irreversible damage to hair scales.

Why doesn't the technical way of light energy heat transfer take away the moisture inside the hair?

Because water is more efficient at absorbing light at certain wavelengths, most of the light will be absorbed by water molecules around the hair, not the surrounding air and the scalp itself. Water molecules selectively absorb infrared light with a certain wavelength to ensure evaporation efficiency. After the external moisture is dried, the infrared light absorption will be reduced, and the absorption is adaptive, so that the whole process will not be overheated and the hair will be protected.

The traditional hair dryer blows the hair hot and dry, resulting in a lot of positive charges. Same-sex repulsion, hair explodes, and temper is very bad. So the negative ion generator of the negative ion blower hits the negative charge on the hair to neutralize the positive charge. But Zuvi's original hair dryer doesn't need this step, because it won't make the hair easy to accumulate charge.

But to be fair, the blowing speed is slower than Dyson's high-speed hair dryer. But the refreshing feeling of scalp and the convenience brought by wireless, such as blowing while watching TV, blowing while walking and so on. , making the concept of "slowing down" irrelevant. And it's really smooth and unexpected after blowing your hair.

So, this is very clear.

The innovation of light energy heat transfer principle brings wireless liberation, natural hair care and optimization of blowing sensation. In my opinion, this is an epoch-making technological revolution. On the whole, it is still wonderful, and the future can be expected.

What IQ tax? What pseudoscience? You can question it, but don't define it directly. It can only be said that the rapid development of domestic hair dryers is still surprising. Perhaps Zuvi's original solar wireless hair dryer needs to be improved, but it is definitely a historic subversion and will also be the promoter of a new round of innovation in the hair dryer market in the future.
