1. Convenient soap box: If some water is added to the ordinary soap box, the soap will be sticky and difficult to take out, and its life will be short. Ping Fan, a student from Tianjin, invented the convenient soap box by using the lever principle. Open the soap box and the soap will rise. Compared with similar products, it has advanced technology and won the first prize of the first national youth invention and creation competition.

2. Use more fire extinguishers: use fire extinguishers to put out the fire in the briquette stove at home. The fire extinguisher will be very hot every time it is used up. We should use this heat energy to serve people. So, I took out the fire tube and welded a kettle. In this way, the fire is extinguished and the water in the kettle is hot, saving coal and hot water.

3. Cover hook: When taking food, always put the cover on the table, so it is easy to burn the table or make distilled water flow onto the table. In order to solve this problem, I designed a lid hook. First find out-log plug, whose diameter is equivalent to the inner diameter of the pot cover. Bend the hook in half with lead wire, insert the straight end of the hook into the log plug, and put the cork into the pot cover. Open the lid and hang it on the side of the pot, which is convenient and hygienic.
