How expensive is the coffee maker? Then make one yourself! The old staff of the national cotton factory made the coffee machine by hand and won the national patent!

Yesterday, the code worker saw a warm and inspiring story.

The protagonist of the story has gray temples, wearing light blue overalls and black trousers, apparently looking like a retired worker. His name is Wang Detao. He is a native of Qingdao and currently runs a coffee shop called K+.

Dianping shows that the cafe is near the Catholic Church and is open from 9:00 to 21:30. It was included by Dianping in 2015, has been included for 6 years now, and won the honor of star merchant of the year in 2020.

Through the pictures posted by consumers, we can see that the store is a small building with little space and only seven or eight tables. The overall decoration style is "forest system", fresh green plants can be seen everywhere.

There is an oversized blackboard at the bar full of food and beverages from K+ Cafe. Of course, there is also a handwritten menu on the table. The main categories are coffee, special coffee, tea, milkshake, ice cream, juice, wine and food. Such a full range of food and beverage items is not common in most boutique cafes. But for consumers, it is a very friendly menu design, so that consumers with different tastes and habits can find food that suits them.

The biggest highlight of K+ is the coffee machine designed and developed by Lao Wang for store production. It is understood that Lao Wang currently has five patents. Lao Wang first applied for a patent in 2008, but invented a utility model of shockproof bed. But the strange thing is that after 2017, Lao Wang's inventions revolve around coffee. What on earth is going on? Next, the code worker will talk about it for you.

Similar to the experience of most "post-70s" generation, Wang Detao, who majored in mechanical and electrical engineering, was assigned to the first National Cotton Factory after graduation and became a technician in repairing looms. "maintenance" became Lao Wang's main job.

In 2009, Lao Wang was exposed to coffee by chance. At that time, the coffee machine in a hotel broke down, but in that era, coffee maintenance had not yet become an industry, so we could only find Lao Wang who did the "maintenance" work. Fortunately, Lao Wang was able to follow the analogy, and after understanding how the coffee machine works, he quickly found the problem. After repairing the coffee machine, Lao Wang was paid 2000 yuan and a cup of freshly ground coffee.

Since then, Lao Wang has formed an inextricable bond with the coffee machine. Accumulate, let Lao Wang become the expert of repairing coffee machine. In 2017, Lao Wang independently designed a coffee machine, and in 2018 he applied for a patent for the design of the coffee machine. Not only did he win two patents for national inventions technically, Lao Wang also participated in the international coffee machine exhibition held in Shanghai, which was recognized by professionals.

Lao Wang revealed to the reporter of Qingdao News that when he repaired the coffee machine for the first time in his life, he did not expect that the coffee machine was not only large in size but also expensive, and each machine cost 50,000 or 60,000 yuan. Who would have thought that a few years later, Lao Wang himself had developed three coffee machines?

For Lao Wang, K+ is not only a place for his retirement, but also his ambition in the coffee field. "K" is not only the initials of "science", but also the meaning of "King'". "K" is Lao Wang's hope that his coffee machine will become the king of kings.
