Wooden box is a kind of packing box. However, this ordinary box can play an important role in dust removal.
Seeing the cutting stone dust on the roadside, many people will cover their noses and leave quickly. Lu Weiyi, a junior high school student in the middle school of Minjiang University, will think about dust removal. As a result, the 15-year-old girl really found a dust-removal method - in a closed box, with three fans, the dust would be sucked into the tank. At present, this dust collection device has applied for a utility model patent from the State Intellectual Property Office.
Car vacuum cleaner gave her inspiration
Before Lunar New Year, Lu Luyi and his family went to play in the suburbs of Fuzhou. Lu Weiyi saw her father's car washing for a long time and there was a lot of dust around the mat. She took out the car vacuum cleaner from the trunk and thoroughly sanitized the car. As a result, when the vacuum cleaner switch is turned on, the dust that is sucked up is ejected from the rear of the vacuum cleaner, and the spray is everywhere. Afterwards, Lu's father found out that he had forgotten to install the filter, and Lu Yi, who was standing by, suddenly had inspiration. If you design a suction box with a filter, it will not solve the dust problem of cutting stones. When the father and daughter have time, they ponder over how to perfect their ideas.
Disposal of dust in the box
They first went to the supermarket to buy a plastic finishing box with a lid, in order to allow flying dust into the box, and then to the hardware market Amoy fans. After returning, they installed a fan on the side of the sorting box and opened a vent on the top. The vents were attached to the cloth to prevent dust from drifting out of the vents. Finally they connected to the power supply and tried to cut the stone. The powder was sucked into the storage box.
With such prototypes, they were not satisfied. Four versions were made before and after that. The material of the box was replaced by a wooden board. There was a fan in the air inlet, a fan in the air outlet and the box, and a sink in the inside. The dust in the suction box was all dissolved into the water.
I believe that in the future, there will be more technological innovations that will make our lives better.
