1, automatic bottle cap Mom always needs two hands to pour oil and soy sauce when cooking. It's inconvenient to hold the bottle in one hand and the bottle cap in the other. The automatic bottle cap (pictured) I designed can be made of a piece of iron, a lead wire and a nut. Dump the oil bottle, gravity makes the nut droop, and automatically pull open the bottle cap; The oil bottle stands upright, the nut is reset by gravity, and the bottle cap closes automatically. This way, you can free up one hand to take the spoon, and you will never be in a hurry again. Just loosen the lead wire bracket, take off the automatic bottle cap and replace it with a bottle stopper, and you can buy oil in the store. It is convenient to hang the lid of the meal, but it is inconvenient to store the meal in summer. Put it in a bamboo basket, the hole is big, flies can climb in, and the bottom area of the basket is limited, so there is not much room for it. The food hanging cover I designed is very simple: bend five disks with lead wire and connect them with four strong strings. Hooks are installed on it, and the periphery is covered with mesh window screens, and the lap joint can be sealed with nylon fasteners. When in use, hang the hanging cover and put the bowl on the disc on each floor. Flies and cockroaches can't get in. When not in use, it can be folded and stored without occupying space.

Mom is busy cooking, and my brother should eat steamed bread quickly. How can a fire achieve two purposes at the same time? Making a simple steamed bun pot will be of great help. Find a small iron basin with a leaking bottom and cut it off. Cut out several rectangles with a length of 9 cm and a width of 7 cm on the basin wall, and break the rectangular iron sheets inward (see the picture above) to form a buns baking box. When cooking, put the basin upside down on the fire, cut the steamed bread into pieces and put it in the steamed bread baking box. This way, the top is fried and the steamed bread slices are baked below.

3. Automatic anti-overflow device When cooking, if there is no one near the pot, the water will easily overflow when the rice pot is opened, which has always been a very annoying thing. In order to solve this problem, I designed an automatic anti-overflow device. The structure is as shown in the figure: a round iron plate is fixed at the button of the pot cover, a wooden beam is placed between the two pot handles, and a magnet (a speaker magnet can be used) is installed at the button of the pot cover, and the distance between the magnet and the round iron plate is fine-tuned, so that it can be sucked up by the magnet as long as the pot cover is slightly opened. On the beam, you can also change the old alarm clock into an alarm clock. First, wind up the alarm clock. When the cover is sucked open, it can knock off the alarm button and give an alarm automatically. With this device, you can rest assured when cooking. When the pot boils, as long as the foam in the pot lifts the lid slightly, the magnet will immediately suck the lid open, thus preventing the pot from overflowing. At the same time, call the police and call the owner.

4. Simple robot eggs have just been boiled in boiling water, and they will be hot when held by hand. I'll tell you the simplest way, you can try it and make sure you are satisfied. Prepare a laundry clip and two spoons, and tie them as shown. Look! How convenient it is to get hot eggs! How about this method?

Call the police when the water boils. Mother asked me to boil the water. While I was boiling water, I was studying. I put the book aside several times to see if the water was boiling. What shall we do? I unscrewed the top button on the top of the lid and cut a small cork according to the size of the lid. Find a metal whistle and cut a slot in the cork according to the size of the whistle mouth. Insert the whistle into the slot. When boiling water, put a cork with a whistle on the top of the pot. As soon as the water boils, the whistle will sound. How convenient it is to wait until you hear the whistle.

6. residual temperature hot water in order to make full use of the heat of the dual-purpose furnace, I welded an arc water tank with iron sheet and fixed it tightly on the furnace wall of the dual-purpose furnace with iron wire. Open a hole in the top of the water tank and install a funnel for irrigation. The faucet is installed at the lower part of the water tank for draining water. This will not affect cooking and heating, and there is hot water at any time.

7. The oil is full, and the kerosene indicator used in my kerosene stove is broken. When my mother refuels, she often overflows because she can't see if she is full of oil. I thought of a way to install two hollow plastic pipes, one long and one short, on the cork of kerosene bottle. The long ones are inserted into the bottom of the bottle, and the exposed ones are generally flush with the short ones. When refueling, insert two plastic pipes into the oil hole of the kerosene stove at the same time. At this time, the short plastic pipe poured oil into the kerosene stove, and the air in the kerosene stove ran into the kerosene bottle along the long plastic pipe. When the oil in the kerosene stove is leveled with the nozzle of the long plastic pipe, there will be no air flow in the long plastic pipe, and the oil in the kerosene bottle will no longer flow. At this time, you will know that the oil has been filled.
