In normal times when we tend to flowers and plants, we need to use various tools such as clippers, shovels, water-absorbing sticks, watering cans, etc. Some of these tools are indispensable in the care process. can sometimes be used.

Today, Xiaofeng will tell you about the most commonly used props in our daily plant care --- watering cans.

Waying cans have different styles and different functions, but today I will tell you about a regular watering can——

Pressure watering. The pressure watering can pour and spray and is convenient to use. In addition, the nozzle can be adjusted, which can be sprayed or sprayed in a straight line, which can be close or far. According to their characteristics, different plants can be watered, and all of them can meet the different water needs of plants. The thread of the atomizer mouth of the water atomizer and the rubber sealing ring of the bottle mouth are unified, the thread of the air cylinder and the inflatable leather ring are unified, and the nozzles can be changed for use.

Although we usually use pressure showers, some people still don't know how it works. What is the principle of operation of a pressure watering can, let's figure it out

How a pressure shower works:

1. Pressure difference. Use the pressure of the water in the watering can and the pressure of the internal air to pump out the water when the pressure is higher than the atmospheric pressure outside the watering can.

2. Relationship between water flow rate and spout cross-sectional area. If there are no small holes in the kettle, pour water directly from the inside,

This is one of the most commonly used garden tool props, here's how it works.

In accordance with the fact that the flow rate of liquid flowing from the same source is the same per unit time, the smaller the hole in the neck of the watering can, the faster the flow rate of water, and vice versa, the less water flow.</p >

A pressure pump is used to force gas into the bottle, and the inlet of the pressure pump can only suck in air, but not exhaust it. atmospheric pressure inside the bottle, the greater the pressure, the farther the jet will be!

A simple understanding is to compare pressure to the substance that pushes water up and out of the watering can. The size and shape of the spout changes the speed and condition of the water.

So what's the right way to use it?

1.Unscrew the cap of the liquid barrel and pour the liquid into the liquid barrel. The amount of liquid loaded at one time should not exceed the cementing ring or the level line no more. The total volume of liquid is about 0.5-2 liters. Then tighten the fluid reservoir cap.

2. Press the wrench several times before inflating. After lubrication, then inflate the fork stem to inflate. After inflating several times, it can be sprayed.

3. Tighten the spray nozzle, unscrew it to spray straight.

4. When the nominal volume of liquid is filled in the liquid barrel, it is not easy to inflate too many times.

5. When the number of pumps reaches the mark line, but still cannot spray mist, check if the nozzle is blocked and if the nozzle cover is screwed too hard, unscrew it and do not press it hard. .

6. After pumping enough air, but not yet spraying, and water dripping from the nozzle, lightly tighten the spray rod nut. , Check whether the O-ring is installed on the plug rod center, and there will be no drip after it is placed in the center.
