Fan Wubing's idea is effective. According to Fan Heng's feedback information, in recent years, the cadres and workers of the Pingyuan Factory have really had a high enthusiasm for work.

"It seems that public opinion propaganda is indeed very important. No wonder the propaganda department has such a high status." Fan Wubing said to Fan Heng.

Fan Heng replied casually as he flipped through the information, "The recording is just a restriction problem. Now the restrictions are about to be cancelled, and technically there is no problem at all. In addition to continuing to produce a small number of single-player orders, most of the production capacity has been invested in the research and development and production of recording and playback all-in-one machines. The machine has basically been finalized, and now it is mainly doing some testing problems and external corrections." As he said that, Fan Heng took the instructions of the new machine to Fan Wubing for viewing.

Fan Heng glanced at him and found the problem.

Pingyuan Factory still adopted the same old method on the instructions for the new Walkman. The instructions are just two thin pages of paper, and the printing is average, with two circuit diagrams on it, as well as the manufacturer's contact number and after-sales service site address, which made people have no desire to read.

"Is this your instruction manual? What problem can this indicate?" Fan Wubing was speechless.

"Is there anything wrong? Our instructions are very detailed, and there are two circuit diagrams." Fan Heng felt a little strange.

"Ah—ah—ah—ah—" Fan Wubing whistled to the sky for a while, then he breathed a sigh of relief, "Oh, bring a few pieces of paper! I'll let you see what the real instruction manual is!"

It took Fan Wubing an entire afternoon to sort out what he thought out. After classifying it, he found that there were more than ten pages of paper. If the illustrations were added, there would probably be a hundred pages of instructions. It covered a lot of knowledge points, and even the most basic single-player principle involved, such as the description of a recording key was as many as two pages, which was entirely referenced to the later computer manual, but it was both knowledgeable and interesting, which made people feel relish.

When Fan Heng saw the instruction manual that Fan Wubing took out, he was immediately attracted. After reading it intently, he breathed a sigh of relief, "I really didn't expect that the instruction manual could be written like this!"

Not to mention that Fan Heng had never seen such a manual, even if most people in China had never seen such a detailed manual. At that time, the manuals of domestic products were basically just one page. Some TV manuals were just a circuit diagram. Where can ordinary people understand it?

"Humanization!" Fan Wubing stretched out a finger and said to Fan Heng, "Humanization is the key to making products! What we need to do is not just products! We must build our own unique brand! Whenever people see any product manual, they must think of the loud name Thunder! This is our goal!"

"Okay, I also believe this is a unique idea! At least after ordinary people have read it, there will be no obstacles to the use of our products! I will arrange for people from the printing workshop to do it tomorrow!" Fan Heng agreed.

Fan Wubing reminded, "You must pay attention to ensuring the printing quality! It is best to use color pages!"

"This is more difficult! I'll try to arrange someone to do it!" Fan Heng scratched his head and said.

The printing factory still uses lead type printing, and typesetting is quite troublesome. Fan Wubing remembered the computer word processing system he used later. It was convenient and I couldn't help but miss it a little.

Fan Heng coughed and frowned.

Fan Wubing looked up and found two bubbles on the corner of his father's mouth, and his lips were very dry.

Now is the season of clear and cool autumn. The weather in the north is very dry. In addition, the work in the factory has been very busy. Fan Heng is anxious because of the Japanese manufacturer's entry into the country, so he has not had a good rest and finally got angry.

"Dad, you're angry!" Fan Wubing said in a depressed manner.

"Oh! I forgot to take medicine again. The root of my tongue hurts these two days." Fan Hengjing's son reminded him, and realized that he had not taken medicine yet, so he took out a few pills from his pocket.

"Sanhuang Tablets! This thing will be useless if you eat it frequently--" Fan Wubing said.

"Where is there any other way?" Fan Heng replied, "The house is very dry during this period. I have put several basins of water into the room, which is useless! It would be great if there was a rain!"

The air is dry! This problem!

Fan Wubing's head suddenly burst into an inspiration and a question came to mind!

"Hahahaha--" Fan Wubing slapped the table and suddenly burst into laughter, "The air is dry! This is another way to make a fortune!"

Fan Heng had long been used to his son's surprise. Seeing him so crazy, he knew that the boy must have thought of something again, so he asked, "Looking at how happy you are, it's because you see bubbles on your mouth, right?"

"Where am I so sinister?" Fan Wubing's enthusiasm remained unabated. "I thought of a way of wealth. Aren't you worried that the Walkman business can't support yourself? So how about we work on another project?"

"Let's tell me, what's your idea?" Fan Heng suddenly became interested. He knew that his son had never disappointed him. Since he said he had a way out, he would definitely make money!

"Air humidifier!" Fan Wubing wrote these big words on the paper.

"Air humidifier? What is this?" After hearing this, Fan Heng intuition believed that this thing was used to improve humidity in the air, but there was no way to start with how to achieve this.

However, Fan Heng touched the big bubble on his mouth and thought that if he could really make this thing, it would be very useful! The only thing he was worried about was that the price was too high, otherwise, there would be no need to worry about the sales of this thing.

Household air humidifiers actually turn AC power into DC power through the transformer, and then pass the oscillation circuit to convert DC power into high-frequency AC power to the ultrasonic atomization head. This ultrasonic atomization head is actually a ceramic oscillator. The ceramic oscillator has a characteristic: applying external force to deform it will output the corresponding voltage and current. On the contrary, applying alternating voltage to it will produce corresponding deformation, that is, vibration. In this way, the ceramic oscillator generates ultrasonic oscillation under the driving force of high-frequency voltage, causing water to atomize, and then sends the water mist out through the fan to achieve the effect of humidifying air.

Fan Wubing knew that humidifiers use ultrasonic atomization head to achieve their function, but he really didn't know how to do this atomization head. However, ultrasonic is not something that is too difficult to do. I believe that someone will always study this content and go to the relevant department to check it out. It is estimated that there is no big problem.

In fact, the domestic technology reserves are not weak, and what they lack is just the driving force to transform technology into practical products.

After Fan Wubing's prompt, Fan Hunter went to the technical department to ask about the humidifier, but found that this thing really exists, and it is still used in industrial environments.

Generally speaking, in modern industrial production and scientific experiments, the importance of air humidity is relatively high. If the humidity cannot meet the requirements, it will cause different degrees of adverse consequences. For example, in textile factories and printing factories, the humidity is generally required to be greater than 60% rh. Otherwise, various dry dust in the air is very likely to cause fires.

The industrial humidifier is generally very large in scale. It moves transversely in the nozzle jacket through the saturated steam from the steam source to enter the evaporation chamber to slow down the steam. In addition, the inertia causes the condensate contained in the steam to be separated and discharged through the condensate outlet at the bottom of the evaporation chamber. The steam separated from the moisture enters the preheated drying chamber, filters and separates the residual water in the steam. The drying steam enters the nozzle through the regulating valve and sprays out from the spray hole with a silence metal mesh, realizing humidification of air.

But if you use it for home use, it is definitely impossible to be so complicated. Fan Heng also found the working principle and sample of the ultrasonic oscillator. He tested it with cold water according to Fan Wubing's description. Sure enough, some of the water can be atomized. As long as it is adjusted to the appropriate water flow and the appropriate input power, there is no problem in realizing the household atomizer.

After Fan Heng's experiment was successful, he ran back home without even having to get off work and told Fan Wubing about this.

"Haha, so I can still realize my idea?" Fan Wubing felt very interesting when he saw his father's excited look.

Fan Heng touched the big bubble at the corner of his mouth and said to Fan Wubing, "Anyway, no matter whether it can be sold or not, I have to make one for it first. This house is too dry!"

Fan Wubing nodded, agreeing deeply.

Dryness is the enemy of health. It not only causes a large amount of water in the human body to lose, causing tight skin, dry mouth and tongue, cleft lips, and fire, but also causes respiratory diseases such as flu and pharyngitis.

Indoor air drying can also cause harm to furniture, floors, home appliances and other objects, shortening service life.

Even in the south, the indoor air humidity in autumn and winter is only below 40% rh in the weather without rain or air conditioning, which is significantly lower than the normal humidity of the room by 40%~70% rh. Adding a humidifier allows all the items in the family and the family to be freed from the dryness, and then enjoy the warm and wet autumn and winter. It is time to enjoy the warm autumn and winter.
