Relief for Mom! Wuhan primary school students' "invention of love" won the national patent

Yangtze River Daily Rong Media May 21 (reporter Yang Feng correspondent Li Sheng) because like to accompany the mother in the kitchen busy, Wuchang Experimental Primary School sixth grade student Zheng Yuanyin, found that the mother used kitchen paper tearing is very difficult, it took more than half a year, for the mother to design a "new type of convenient paper kitchen paper fixed seat", and the general tearing paper mouth using serrated blades different, Zheng Yuanyin designed a wet paper roller dipped in water, easier to tear than the serrated mouth, thus solving the mother's "troubles", but also won the national utility model patent.

Zheng Yuanyin said that she usually likes to cook with her mother in the kitchen, sometimes giving her mother a hand, sometimes learning how to cook vegetables. In the process of observation, she found that her mother was very upset every time she used kitchen paper, kitchen paper is more resilient than ordinary paper products, and it is not easy to tear. Mom always lamented that if you could easily take the paper with one hand, it would be good! Zheng Yuanyin listened to this sentence in her heart, and she hoped to design a fixed seat that was convenient for picking up paper and installed it in the kitchen, so that her mother could be more comfortable when cooking.

After Zheng Yuanyin said what she thought, she won the support of her parents. Her parents accompanied her to the supermarket to inspect the tear-off paper fixing seats currently on the market, and found that they were not satisfactory. "Most are serrated, and it's okay to tear soft paper towels, but it's very difficult to tear kitchen paper." Zheng Yuanyin said. In addition to the serrated mouth, Zheng Yuanyin also considered fixing the clamp rod to tear, and it could not meet her mother's expectations.

In an experiment, Zheng Yuanyin found that the water-stained kitchen paper was very easy to tear, "So why not design a water collection sink on the fixed seat?" Every time you tear the paper, flick a mechanism to make the incision wet, isn't it easy to tear? After the birth of this idea, Zheng Yuanyin was very excited. She and her parents designed, drew, modeled, and after many experiments, a new kitchen paper holder that was easy to pick up paper was finally made.

Zheng Yuanyin's small invention.

This holder is not much different from the general paper drawer holder, but a discreet sink is designed, and when used, water is injected into the sink and kitchen paper is inserted into the paper sleeve. When kitchen paper is needed, you can directly drag the paper, get the appropriate paper length, the user uses the toggle head to dial the swing frame, so that the wet paper roller comes out of the collection sink, the wet paper roller dipped in water is quickly absorbed by the kitchen paper, forming a neat tear line, at this time, the user can easily tear off the kitchen paper, the edge is neat, the tear is easy, especially suitable for use in the kitchen.

With this obvious effect, safe and low-cost small invention, Zheng Yuanyin won the national utility model patent.

Zheng Yuanyin's science teacher Guo Yingxin said that Zheng Yuanyin's usual hands-on ability is very strong, and he has also designed a solar automatic watering system before, which can automatically detect the dry moisture of the soil, and if it is too dry, it can automatically water the plants.
