Mineral water bottle for washing machine drainage

1. This one is definitely not good. The sealing of the self-made one is not good. It is easy to breed bacteria if there is leakage. Besides, the mineral water bottle can not be used for a long time. After all, the glue will proce chemicals if it is used for a long time. It is not good for health, and the filtered water is not eaten by family members. Choose a popular brand, aorun and Midea are good, with high cost performance.

2. Your idea is very good and innovative. Even if it's made, it can't be used normally. The mineral water bottle can't bear the water pressure.

3. Unknown_Error

4. Steps: 1. Buy a bottle of yogurt (plastic bottle) from a cold drink shop and drink the yogurt. 2. Wash the yogurt bottle and cut off the bottom with scissors. 3. Take down the hollow cover in the middle of the original floor drain. 4. Insert the bottom of the yogurt bottle upward into the central round hole of the cover. 5. Put the cover with bottle back into the floor drain, and it's done.

It uses the principle of air pressure to make the water move

there are many examples of using the principle of air pressure in life. The plastic hook with suction cup can be used to hang things when it is pressed on a flat wall; The piston type and centrifugal type pump pump water from the lower part to the higher part

squeeze out the air in the pen tube, and let go the ink to suck in the pen tube; It's easy to boil the food in a pressure cooker; A small hole is opened on the cover of the tea so that the water can be easily poured out; There are also high-pressure boilers, agricultural sprayers, straw suction drinks, syringe syringe syringes, etc., all related to atmospheric pressure. p>

the cause of water cycle

the external cause of water cycle formation is solar radiation and gravity, which provide the change of water physical state and movement energy for water cycle; the internal cause of water cycle formation is the characteristics of water in gas, liquid and solid forms easy to transform each other under normal environmental conditions

precipitation, evaporation and runoff are the three most important links in the process of water cycle, which determine the global water balance and the total amount of water resources in a region

6. 1. Cut off the top half of the mineral water bottle
2. Put some coarse sand, fine sand, activated carbon and cotton in it
3. Plant water plants in it, so that the fish will have oxygen, and the fish feces will become nutrients of water plants
4. Put about 2 / 3 water in it, and some ckweed on it, Extended data: the filter consists of cylinder, stainless steel filter, sewage discharge part, transmission device and electrical control part. When the filter is working, the water to be filtered flows through the filter screen through the nozzle filter, and enters the pipeline required by the user through the outlet for process circulation, and the particles and impurities in the water are trapped in the filter screen. With such continuous circulation, more and more particles are intercepted, and the filtration speed is slower and slower. However, the inlet sewage is still flowing in, and the filter hole will be smaller and smaller, resulting in a pressure difference between the inlet and outlet. When the large difference reaches the set value, the differential pressure transmitter transmits the electrical signal to the controller, and the control system starts the drive motor to drive the shaft to rotate through the transmission components, At the same time, the drain outlet is opened and discharged from the drain outlet. When the filter screen is cleaned, the differential pressure drops to the minimum value, and the system returns to the initial filtering state, and the system operates normally

There are many examples of using the principle of air pressure in life. A plastic hook with a suction cup can be used to hang things when it is pressed on a flat wall; The piston type and centrifugal pump pump pump the water from the lower part to the higher part, extrude the air in the pen pipe, and then draw the ink into the pen pipe; It's easy to boil the food in a pressure cooker; A small hole is opened on the cover of the tea so that the water can be easily poured out; There are high-pressure boilers, agricultural sprayers, straw suckers, syringe syringes, and so on, all related to atmospheric pressure

expansion data :

air pressure is related to altitude, air temperature and atmospheric density, and generally decreases exponentially with height. p> There are diurnal and annual variations of atmospheric pressure. In a year, the pressure is higher in winter than in summer. In a day, the air pressure has a maximum value and a minimum value, which appear at 9-10 o'clock and 15-16 o'clock respectively, and a second high value and a second low value, which appear at 21-22 o'clock and 3-4 o'clock respectively. The diurnal variation of atmospheric pressure is small, generally 0.1-0.4 kPa, and decreases with the increase of latitude

The change of atmospheric pressure is closely related to wind and weather, so it is an important meteorological factor. The commonly used pressure units are PA, mm Hg and MB

The conversion relationship between them is: 100 Pa = 1 mbar ≈ 3 / 4 mm Hg. The instruments commonly used to measure air pressure in meteorological observation include mercury barometer, air box barometer and barometer. At 0 ℃, the pressure of 760 mm vertical mercury column was first measured by Italian scientist Torricelli

8. First, take a small empty bottle of mineral water (300-350 ml), wash it and dry it in the air, then put it in an empty bottle with soybeans or coarse sand, or one third or half of the bottle, seal the mouth of the bottle, tie it with a ribbon, or stick some decorative patterns on the bottle body< Other magical functions of mineral water bottle:

cockroach catcher:
tools:
1. Mineral water bottle (the rounder, the smoother, the better)
2. Adhesive tape
3. Art knife
4. Salad oil
5. Cotton stick (long)
6. Toilet paper
7. Sugar
steps:
1. Prepare the materials first
2. Cut the upper end of the mineral water bottle with an art knife
3. Use a long cotton swab to coat the mineral water bottle with oil (cockroaches with oil can't climb out if they fall into the trap), but don't get oil on the outside of the bottle, otherwise our VIP can't climb in
4. Lay a folded toilet paper on the bottom of the bottle, sprinkle some sugar and pour some water to make the paper wet
5. Put the bottle cap upside down on the bottle and stick it with adhesive tape
6. It's best to put it in the place where cockroaches often appear and close to the wall (the trap itself should be fixed, and if it falls down, it will give the cockroaches a chance to escape)< br />

It is suggested that the mineral water bottle should be a small one, half filled with sand or grain, and pasted with color strips on the outside of the bottle

1. preparation tools: mineral water bottle, cake paper, color tape, color pen, art knife

2. use an empty mineral water bottle without water to fill it with half a bottle of rice or sand, or a mixture of half a bottle of sand and rice. In this way, it can be used as

3. bottle, mineral water bottle and yogurt bottle. Put mung beans, corn or pebbles in the waste bottles, and cover them well. Cut the colored paper such as waste cardboard into your favorite patterns on the bottles, and stick them on with glue to decorate them. Then you can make a sand hammer. You can play, have music lessons, play rhythm, and do instrument exercises for two people< br />
