Why does the mouth blow things away when you blow and you can t suck them back when you inhale?

Blowing or inhaling is a collection of airflow, forming a column that flows in one direction. When you blow up, you feel a lot because your fingers (or something) are in the way of the airflow, and the airflow is resisted, so you are stressed. When you inhale, your mouth collects the surrounding gas, no matter where your fingers are, as long as you don't seal your mouth, it is impossible to block the collection of airflow, so the resistance is small, and the force on your fingers is also small.

If you can feel it in your mouth, then the force you experience is just as great.

In general, the principle of inhalation or exhalation is the same, but the direction and purpose are different. But they are all collected by collecting gases, and then condensing them into a columnar stream of air through the mouth, which changes from dispersion to condensation, which is more powerful. But the resistance is very different.

The air we blow out comes from the lungs, and some of these gases go through systemic and pulmonary circulation in the body, so the temperature of the gas is comparable to the body temperature. When we breathe, the mouth is opened relatively large, and when we breathe, the mouth is opened smaller. The rate at which the lungs exhale outside is almost constant, i.e., the flow rate is constant, so the rate of airflow is greater when blowing than when breathing.

There is also friction between the gases, and the blown gas will carry the cooler air around it and move together.

When blowing, the air column is thin and the velocity is large, so there is more entrained cold air, and the proportion of cold air when it reaches the human ** is large, and these fast-flowing gases can accelerate the evaporation of sweat, so it feels cool. The gas column is coarse, the rate is small, the entrained cold air is less, and almost all of the hot gas is out when it reaches the person, not only the temperature of the gas is high, but also the evaporation effect on sweat is very small, so it feels hot.

Because the difference in the magnitude of resistance will be large depending on the direction.

There is very little space in the mouth, so you can gather the strength to blow out, but it is difficult to inhale.

That's because the force of suction is very small, so it can't be sucked back.

Because the force of the blow is greater, the inhalation will not.

Because there is a certain resistance of the air.

Because blowing backwards only has the weight of the object, it is easy.

Inhale or exhale on the same principle, but in a different direction and purpose.

Because there is a lot of space outside the mouth, you can't suck it back.

The resistance on both sides is different, and the resistance will be less when blowing.

1. The straw is too long and the mouth is too high relative to the drink.

2. The suction power is too small, especially the sealed package, there is no ventilation port. When sucking, negative pressure is generated in the bottle, which is more difficult to suck.

3. The amount of air blowing on the sealed package is small, and the bottle is pressurized when blowing, but the increased pressure is not enough to make the drink reach the height of the mouth. Especially for large bottle packaging.

4. Blow on the bottle, but there is a loophole in the beverage packaging, and the blown air runs out of the loophole. In this way, the natural pressurization in the bottle is small or even none.

5. The straw is blocked.

6. The liquid in the bottle has high viscosity and thickness.

Because of the air leak.

Thank you for your question.

This is not going to be, it is normal to have a sound when inhaling, if you don't press the hole when blowing, then don't blow hard, in the case of full press, blow hard a few times should be OK, I guess your gourd silk is a little long. I've been in this situation before.

The reed is protruding outward, in this case, it may be that the reed is trapped underneath, or it may be that the front and back are reversed when installing, if it is trapped, it can be picked out, if it is reversed, it can be removed and reinstalled, and it is really not possible to replace a reed.

It proves that the momentum in your mouth is not from the dantian, and the inhalation is not stopped in time.

Do not inhale when blowing the gourd wire, as this will damage the reed.

When you can't blow it, push hard, don't be careful, that won't work.

It may be that I didn't pay attention to the blowing method when I blew before, and the high note should be lighter, and the breath is spit out when I blow.

Try it hard, either the reed is broken, it's best not to fix it yourself, otherwise it's more troublesome if it's broken, where to buy it, you can find it back and see.

It is normal to have a sound when inhaling.

If you blow without sound, are you not practicing properly?

In general, beginners may not be able to blow when they start blowing.

Take it out and take a look, maybe it's mildew in saliva, just wipe it clean.

You can remove it and repair it yourself.

There should be something wrong with the reeds inside.

Blowing is carbon dioxide, and inhaling oxygen, don't believe you try to suck carbon dioxide.

You put the candle in the jar and then inhale and it goes out.

Here's how to do it:

1. Do a good job of the basic relaxation variation - back support or another variation of a reclining relaxation. Once you're comfortable, start breathing slowly and gently. With each inhalation, gradually lengthen the length of your breath.

As you exhale, increase the length of your breath so that the length of your breath is equal to that of your inhale.

2. When you start to do breathing exercises, first inhale a normal amount of air, and then extend the exhalation time. Then, resume normal breathing. Inhale normally again, then extend the exhalation time. Then return to normal inhalation and exhalation.

3. Don't let yourself feel short of breath or out of breath at any time. Continue with a normal inhale, followed by an exhale that lasts twice as long. Count as you inhale:

1,001,1,002,1,003。As you exhale, you count: 1,001, 1,002, 1,003, 1,004, 1,005, 1,006.

Make sure that after each long exhale, follow with a normal exhalation and inhalation. Hold this rhythm for about five minutes. A prolonged exhalation increases the pressure in the lungs and causes the airways to dilate, making the next inhale easier.

This exercise is especially effective for people with asthma.

4. At the end, do a few normal exhalations and inhales, paying attention to the effect of such breathing. Variation of the Restore Basic Relaxation Pose – Back Support or Another Variation – Reclining Relaxation. Then gently fall to the side and lie there for a few breaths, using your arms to help you sit up.

Pinch your nose and blow into the air, then squeeze your heart with both hands outside your chest.

Breathe in outside, inhale and then blow on the first responder, never as if you were exhaling. To blow.
