Fan Heng and Fan Wuji, father and son, have recently been refining the structure of household humidifiers.

The technical content of this thing is not too high, mainly relying on a ceramic oscillator to break up the water molecules and atomize them into ultrafine particles of one to five microns, and diffuse the water mist into the air through the pneumatic device, so as to achieve the purpose of uniformly humidifying the air.

Fan Wuxian mainly put forward a design roadmap in terms of modeling, originally Fan Heng had not figured out how to continuously feed water for the ceramic oscillator, but when Fan Wuxian shamelessly drew the split structure for him, it all became very simple.

The later improvement work is mainly focused on power control, to ensure the safety of electricity, after all, this thing is not handled well, it is easy to cause electric shock accidents. Fan Wuxi directly referred to the design of the concave and convex plug on the computer power supply, and copied it to use, which made Fan Heng, who was used to using ordinary plugs, shine, after all, this thing is rarely seen in China now.

The core part of the final sample is only the size of a fist, but the volume of the specific finished product still depends on the size of the water tank used and the environment in which it is used.

"It seems that the finished product will be able to be launched before New Year's Day." Fan Heng leaned on the sofa, looked at the humidifier that kept emitting a white cold mist at home, and said to Fan Wuxian quite optimistically.

Not to mention, this thing to the home, the effect is indeed far from being able to compare with a few basins of cold water, its humidification intensity is large, the humidification is uniform, the humidification efficiency is high, and the energy saving, power saving, long service life, the use effect is satisfactory.

It's not very noisy, at most you can hear the sound of water in the dead of night, which is basically negligible compared to a dry mouth.

"What are you two fathers and sons doing, what are you talking about? cough-cough-" As soon as Zhang Mei entered the house, she found that the feeling inside the house was a little different, and Fan Heng and Fan Wuxian both didn't go out at home, so they couldn't help but ask curiously.

"Huh? Why did mom cough? Fan Wuxi's ears were sharp enough, and his heart was fine, and he immediately noticed that Zhang Mei was coughing.

Zhang Mei tapped her chest with her hand, "Recently, there has been a virus with a cold, and I accidentally infected it, so stay away from me!" ”

"Go to the hospital and hang a bottle of liquid, the cold surnamed the virus is very stubborn, and it's not a way for you to hold on so hard. At the end of the year, everyone's things are busy, which is not conducive to recovery. Fan Heng suggested.

"The most worrying thing is lung infection, in which case I can only be hospitalized, but there are a lot of things in the unit, and I can't do without people at all." Zhang Mei coughed again and said with a frown.

Fan Wuxian's gaze fell on the humidifier, and he suddenly had an idea. Originally, the winter colds were basically caused by dry air, and when the humidity was low, the viruses seemed to be more likely to attack people's lungs, so it seemed necessary to get a humidifier for my mother to use in the office.

So Fan Wuxian said, "Dad, we have to work overtime, hurry up and get one for my mother to use first, whether it is beautiful or not is second." ”

"There's no need to make it now, send this one to the office first, and let's get another one for home use." Fan Heng nodded in agreement, seeing his wife working so hard, he was very distressed, and immediately made a decision when he heard the words.

Although Zhang Mei didn't know what the father and son were doing, she found that since she entered the house, her cough seemed to be better, her lungs were much more comfortable, and the air in the home seemed to have a more moisturizing feeling compared with the outside.

Then she noticed the strange thing that looked so ugly, and kept coming out of the white mist, and asked, "What is this?" ”

"This is an air humidifier, which we just came up with, which can avoid all kinds of harmful phenomena caused by dry air. In the future, with this thing, you don't have to worry too much about getting hot in autumn and winter, and it is also good for your skin. Fan replied.

"It's so amazing?!" Zhang Mei walked over, stretched out her hand and walked through the white mist, and found that there was a cool feeling, not the imaginary white mist, and couldn't help but ask with some curiosity, "Why isn't this water vapor hot?" ”

She thought that since this thing was used for electricity, it must have heated the water and turned it into water vapor to send it to the air, and it should be hot, but in fact it was not the case, this water mist was actually cold.

Fan Wuxi took the water tank off the humidifier, revealing the remaining part of the water and the concussion head inside, and pointed to the white mist that was gurgling and introduced to Zhang Mei, "This is the use of ceramic oscillators to generate ultrasonic waves, and use ultrasonic waves to disperse water molecules, so that when the water mist volatilized in the air, it needs to absorb heat, so you feel that they are cool and silky." In fact, this humidifier also has other uses, such as applying cold compresses to the facial skin, or adding chemicals to medical treatment. For a lung infection like my mother's current condition, this air humidifier is the most suitable for auxiliary treatment! ”

"How do you get it?" When Zhang Mei heard that this thing could cure her cough, she immediately became interested.

The cough in winter is very annoying, not to mention that it is uncomfortable, and it also affects the work, and there are many meetings at the end of the year, and I sit on the rostrum to speak, and cough a few times from time to time, which affects the atmosphere very much.

"Probably anti-inflammatory drugs that can be used to treat lung infections can be added, and I have to ask in the hospital for details, although I know that this is feasible, but I don't know what drugs they usually add to them-" Fan Wuxian was asked at this moment, and replied with some uncertainty.

"Oh, then I'll know." What Zhang Mei wants to ask is what can be added to this water, whether it will affect its use, and what drugs to add, basically the drugs she is taking and the anti-inflammatory drugs injected can be used.

So she took out a lot of medicines from the bag, crushed them and melted them in water, and then stirred them well until there was no precipitation, which allowed Fan Wuxi to install the water tank, and then dragged it to the bedroom, and finally Zhang Mei said to the father and son, "I'll go sleep for a while, you can make lunch!" Then he closed the door to his bedroom and went to sleep.

The father and son looked at each other, and finally Fan Wuxian asked Fan Hengdao, "Can you cook?" ”

"Nonsense! Simmer some rice, get a scrambled egg with tomatoes, and then scramble shredded potatoes, I don't know how to do this?! Fan Heng stiffened his neck, his eyes widened, and he said to Fan Wuxian very unconvinced.

"Your recipe is unscientific, but when I was growing my body, I couldn't do it without nutrition! You are dealing with it so recklessly, obviously you have not fulfilled your responsibilities as a parent! It seriously violates the rights and interests of women and children! Fan Wuxian said seriously.

"So what do you have a good idea? Anyway, I'm only going to cook these two dishes—" Fan Heng said with a blushing face.

Fan Wuxian scratched his head and said, "Let me think about it, first get a sweet and sour pork ribs, then a stir-fried kidney flower, a meatball soup, and finally a tamale, the staple food rice is good, but unfortunately there are no greens except Chinese cabbage and potatoes in winter, alas!" ”

Ordinary families in this period often eat potatoes, radishes and Chinese cabbage in winter, because greenhouse technology has not yet risen, so it is very difficult for northerners to eat fresh vegetables. When winter comes, everyone pulls Chinese cabbage into their homes as winter storage vegetables, and some people also pickle sauerkraut to eat, which can be regarded as a change of taste.

Although Fan Wuxian made a lot of money, he didn't think of changing this status quo, he naturally has an advantage compared with others, that is, he never has to worry about pork, and he doesn't need to rely on meat tickets to buy pork like others. In the words of Boss Wang, what did we start for? It's not easy to eat pork if you want to, you can pick thousands of pigs!

Fan Wuxi's cooking skills were trained by himself for more than ten years, so it is natural to say that in less than an hour, the meal was on the table, looking at the fragrant table of food, Fan Heng couldn't help but move his index finger, and grinned happily, "I can't see that your kid can even do this, it was a waste of talent before!" In the future, you will be contracted for our kitchen! Your brother is only in high school, and he is so nervous about studying, you have to make sure that his nutrition is balanced! It's that your parents are not in good health, and they are all handed over to you to recuperate, as the saying goes, medicine is not as good as food! ”

"Isn't it!" When Fan Wuxian heard his father say that he would let him contract the kitchen, his face suddenly turned green, "You don't want to think about how old I am?" Even after the New Year, he is only eight years old! Let an eight-year-old cook for you, you can figure it out! You're child abuse! The flower bones that destroyed the motherland! ”

"Just talk, you're serious—" Fan Heng said curtly, "Go and see if your mother has woken up?" By the way, I asked her to come out to eat. Look at the time, it's time for Fan Kang to come back too! ”

Before Fan Heng's words fell, Fan Heng pushed the door in, "I'm back!" ”

Zhang Mei slept very deeply, and when Fan Wuxian entered the bedroom, he found that she had turned on the humidifier too much, and the room was filled with white mist and a smell of medicine, so he turned the knob down a little, and then began to push Zhang Mei.

It took Zhang Mei to wake up for a long time, and when she saw Fan Wuxi, she was shocked, "Ah! I actually fell asleep! I haven't slept so comfortably in two days! Looks like this thing you're doing really works! ”

Not only is the air moist, but the added medicine is directly supplied to the lungs through the mist, and the effect is naturally much better than entering the body through blood circulation.

"This thing, it's really good!" Deputy Director Zhang approvingly.
