Looking at the equipment that Xiao Brother Lu took out, many users in the live broadcast room began to hold their breath.

Little Brother Lu was also holding his breath.

First of all, the cleaner needs to be turned on, and Xiao Lu Ge chooses the standard mode.

In this mode, the maglev linear motor vibrates at a frequency of 80,000 vibrations per minute.

This means that the brush head vibrates linearly 1,333 times per second.

As soon as the cleaner was turned on, the painting style in the live broadcast room immediately changed.

Because of the continuous humming sound, the brush head of the cleaner in Xiao Luge's hand seems to be marked with a layer of mosaic, and users can't see the original appearance of the brush head at all.

There is only a shadow of a model lake.

"It feels good to hold in your hand." Brother Lu shook the vibrating cleaner and said with a smile: "Although the brush head is vibrating wildly, the vibration here in the handle of the cleaner is not strong, and there is no numbness in the hands that cannot be held." ”

"This also shows that the vibration amplitude of the brush head back and forth is not large, it is the kind of high-frequency and small-amplitude linear movement."

"Now, I'm going to turn on the speed camera."

Xiao Lu Ge introduced while turning on the camera recording switch to let the camera enter the working state.

Then, Xiao Lu Ge put the brush head of the cleaner in front of the camera, held the straw in his other hand, and gently dripped a drop of water on the top of the brush head.

The water droplets from dripping to hitting the brush head in the blink of an eye.

But neither Brother Xiao Lu nor the audience could see the scene of the water droplets falling on the brush head.

The droplets are barely visible, but the moment they touch the brush head, the droplets disappear.

It's like magic, and it just disappears.

Little Brother Lu blinked, followed by another drop.

In the same picture, the water droplets disappear the moment they fall on the brush head.

"Okay, okay, it seems that you can't see the results with the naked eye."

"Let's look at the replay of the high-speed camera."

Brother Lu first turned off the high-speed camera, and then turned off the cleaner.

Then take out the camcorder memory card and insert it into the computer, and then Xiao Lu Ge pointed the live broadcast camera at the computer screen.

The high-speed camera is a bargain for a few thousand dollars, and it can only shoot 545 frames per second.

But it is enough to observe water droplets, after all, the human eye can only see a maximum of 30 frames per second, and this camera is close to 20 times the frame rate of the human eye.

Use professional image software to play, first the normal multiple, the moment when Xiao Lu Ge found the water droplets dripping.

Then turn on slow play, and directly slow down to maximize.

In slow motion, the droplets of water that were originally dripping seem to be frozen in motion.

It took almost twenty seconds for it to drip from the dropper to the point where it was about to touch the surface of the brush head.

It is also in the slow down that users can barely see the movement of the brush head of the cleaner.

It pans quickly back and forth.

When the almost transparent water droplet comes into contact with the brush head, the brush head shifts back and forth, and it is immediately broken.

For the first blow, the brush head is coarsely grained with a surface coating, allowing water droplets to splash forward.

However, before the droplets could spread forward, the fast-moving brush head instantly returned, striking the droplets moving forward at high speed again.

This blow is no less than the collision of two supersonic missiles.

When the water droplets come into contact with the particles on the surface of the brush head, the fine water droplets that have been scattered immediately burst open.

A circle of air waves, appearing in the collision zone.

All the tiny droplets vanished, turning into a circle of mist that spread out to the surroundings.

"......" Little Brother Lu looked at the monitor screen in amazement.

The hundreds of thousands of users who watched the live broadcast were not much better.

The visual explosion in the first five seconds of the advertisement was so easily reproduced?

The droplets of water literally turn into mist.

"Kneel ......"

"There is a big hand who understands the principle to popularize science, why can the first drop of water still be seen clearly into a small drop of water, and the second impact will directly explode into a white mist?"

"Little Brother Lu, pour some water on his arm and see if he will break the skin on his arm."

"It's so fast, it feels like it's like a bubble of sound."

"Little Brother Lu, put it on your skin and try it."

"Yes, yes~ give me a try."

The effect of water droplets is so explosive, users quickly encourage Xiao Brother Lu to help them experience it for themselves.

Brother Lu satisfied the ideas of these users, he poured some water on his arm, and then activated the cleaner again.

However, as soon as the brush head was put on his arm, the corners of Xiao Lu's mouth were crooked, and his expression was unexpected.

"Hey~ it's so comfortable." Xiao Lu Ge picked up the brush head with some surprise, and something even more unexpected happened.

Around the piece of skin that the brush had just touched, a circle of gray things appeared.

And the piece of skin that the brush head touched turned out to be a little fairer than the surrounding skin.

This gray thing is all too familiar to everyone.

It's the ash that comes down.

？？？

Brother Xiao Lu didn't feel embarrassed, he had done all the shower gel baths live, and now this scene is pediatric.

It's just that he didn't expect that the cleaner would be placed on the skin for only a second or two, and the skin would be cleaned.

And I don't feel any pain at all, just the comfort of a gentle massage.

These users asked Brother Lu how he felt, and after Brother Lu told him how he felt, they didn't believe it.

The water droplets drip on it and directly turn into mist, how can it be comfortable to put on the skin?

Then Brother Lu washed his entire arm, and after washing, compared with the other arm, the effect was obvious.

And the arm that has been washed by the cleaner shows no signs of redness.

Hundreds of thousands of users, look at Xiao Brother Lu's arm.

If you look at another machine that has been dismantled into parts, you can clearly see that the internal parts are very well made, and the internal parts are full of electronic and mechanical aesthetics.

At this moment, hundreds of thousands of users in the live broadcast room are shouting that they want to place an order to buy one.

Of course, a lot of it is just shouting.

I was really tempted to decide to buy one, and most of them were girls who loved beauty.

However, the cleaner will not be released until the next day, and now they can only enjoy it in Xiao Lu's live broadcast room first.

While they were fascinated, they excitedly shared the news that the cleaning instrument products were about to be launched with their friends.

……

The next morning.

In the past few days, the Second Angel Technology account has risen to 15 million followers.

As of 12 o'clock this morning, 80,000 cleaning instruments were stocked in the storeroom of the building.

Because the grating sensor of the magnetic levitation linear motor can only be assembled manually for the time being, even if the current production capacity is stretched to the limit, there is only an output of 20,000 motors per day.

This output is also the result of Song Yu's special deployment of hundreds of skilled workers in the headquarters factory to set up a special assembly workshop to help the motor factory assemble grating sensors.

Fortunately, the grating sensor already has an automated solution, and the placement machine production plant is expected to be able to come up with the first automatic placement prototype next week.

Thirty p.m.

The company's press conference site has also been arranged, and Ye Ran is ready to hold a small press conference for the cleaning instrument.

The press conference is still live, and the host is still You Dong.

Two o'clock in the afternoon.

I don't know how many girls have been looking forward to the [Magic Cleaner] press conference has finally begun.
