What dangers may be encountered when using a thermos cup?

The thermos cup is very convenient to see, in fact, if it is not used properly, it will also bring us danger.

1. Improper use of the thermos cup may be burned.

Thermos cups are also very common in life, and we will often hold some hot water, especially in winter, if you can drink some hot water at any time, it is also a very warm thing.

But if we open the thermos cup again, it is very likely that we will be scalded by the hot water inside, most of which will happen to children, because they don't know that it is filled with hot water, so it is very likely to be accidentally injured by the hot water inside.

Second, if the thermos cup is not qualified, it may lead to unhealthy water drinking. Most thermos cups will be made of stainless steel, and now the more common one is 304 stainless steel.

However, those unqualified thermos cups are made of 201 stainless steel.

Manufactured.

201 stainless steel belongs to industrial stainless steel, not too acid-resistant, not too alkali-resistant, usually used in such as straps, decoration materials, etc., if you meet those unconscionable businessmen they will directly use high manganese and low nickel just to replace the liner.

The thermos cup made of high manganese and low nickel can easily lead to chromium, nickel and manganese. It enters our body through water, thus causing certain harm to our physical health.

However, as long as the quality of the thermos cup has passed the inspection, it can be used normally, so it does not mean that all the thermos cups are problematic and cannot be used.

Third, the thermos cup may also happen**. A girl in Fuzhou, Fujian Province, because she soaked red dates in a thermos cup for more than 10 days, caused ** to occur when she opened it, causing her eyeballs to burst.

This is actually mainly because jujube is prone to produce some fermenting gases, so it will produce a huge momentum when it is opened, which will occur.

So the thermos mug is convenient and convenientHowever, we still have to try to choose a qualified thermos cup and use it correctlyso that it does us no harm.

It is necessary to pay attention to observe whether the thermos cup has passed the quality and safety inspection, because some thermos cups will use excessive heavy metal substances for production in order to save money, resulting in the hot water entering the water becoming toxic water, so be very careful.

You may encounter a thermos cup leaking and then accidentally be burned, or the lid is not tightened when you use it, resulting in water leakage and burns, and there is also a situation where you use a thermos cup to fill carbonated drinks, if the shaking is too violent, the cup will be sprayed on the face. Sometimes when you drink it, you forget that this is a thermos cup, and the water in it is so hot that your lips are burned.

Burns, heavy metal poisoning. Sudden spilling of hot water in a thermos cup may cause burns, so it is best not to pour boiling water. Heavy metal poisoning means that the quality of the thermos cup may be substandard, and it should be purchased through regular channels.

First scald the bottle with a small amount of boiling water to sanitize the bacteria and viruses in the bottle.

After filling the bottle with hot water, be sure to tighten the cap to prevent leakage and burn yourself.

The water can't be filled too much, and the thermos cup will leak if it is filled with too much water.

Before using the new product, it must be scalded with boiling water (or add some edible detergent) several times for high temperature disinfection.

Please overfill the cup in a hurry to avoid boiling water spilling and scalding when the lid is tightened.

Please drink slowly when hot to avoid burns.

The thermos cup is filled with 45 degrees of water, and the lid of the cup will not release harmful substances。The lid of the thermos cup will not release harmful substances, regardless of the thermos cup, it should not be toxic, if the thermos cup is toxic somewhere, the health test report will not be qualified, so ah, buy a thermos cup and buy a regular manufacturer.

Generally, it can be sold on the market, which is basically qualified and should not be toxic, so the cup lid will not release harmful substances. The lids of the thermos cup are all environmentally friendly plastic, and the lids of the regular brand of thermos cups are made of PP material, which is a safe plastic material, and the inner liner of the thermos cup is 304 stainless steel, which is also a safe raw material for the inner tank.

The thermos mug has a function

The appearance is smooth and odorless, and after pouring boiling water, a thermos cup with no heat sensation in your hand can be called a good cup. The interior and exterior are stainless steel, refined with advanced vacuum technology, elegant shape, seamless inner tank, good sealing performance, and good thermal insulation performance. Ice cubes can be placed or hot drinks can be served.

At the same time, functional innovation and detailed design also make the thermos cup more connotative and practical.

Versatile, a multi-purpose cup has become a popular practice of ** thermos cup. Almost every thermos cup has its own distinctive characteristics, some are double lid design, as long as you press the red key in the middle when driving, the water will automatically flow out, and will not splash wet in the car, and some are designed in the middle of the thermos cup with a tea partition design, which can quickly filter tea and tea, which is very suitable for small white-collar workers in the office.

Some are double-cup design, the bottom box lid also has a dark grid for tea, sugar, coffee, etc., and the vacuum liner made of stainless steel double-layer can not only hold water, but also ice water, etc., some cups also have a simmering function, the thermos cup with the least function also has at least 2 more functions, and the most functional thermos cup has 4 5 functions, whether it is traveling or home use is very convenient.

First, pay attention to the material.

Nowadays, there are a large number of thermos cups on the market, a variety of styles make many people dazzled, and the quality is uneven, if you accidentally buy a poor quality thermos cup, the insulation effect is poor, not to mention, if the stainless steel quality in the thermos cup is poor, it will affect everyone's health. Stainless steel is made of iron and various metals, and when it reacts with electric ions in water, some metal elements are easy to be separated, and if people drink a large amount of water containing heavy metals for a long time, it may lead to metal poisoning. However, you don't have to be afraid to see here, the country has specific standards for food-grade stainless steel, the common ones are, the corrosion resistance of food-grade stainless steel is better, and there is a certain guarantee for everyone's health.

Second, do not soak red dates, wolfberries, etc.

Nowadays, it is often heard that "when people reach middle age, they have to soak wolfberries in a thermos cup", but the lessons of Fuzhou girls make people have to feel scared. Why can't you soak wolfberries and red dates in the thermos cup? First of all, wolfberries and red dates contain a lot of nutrients, and the nutritional value will decrease if they are soaked in water at a higher temperature for a long time.

Secondly, wolfberries and jujubes are soaked in such an environment for a long time, and the microorganisms in them will begin to ferment and produce some gases, which are easy to occur when they are suddenly opened, harming everyone's health. Therefore, in daily life, try not to soak things in the thermos cup, if you really need to soak it, then the soaking time should not be too long, and try not to completely seal it to avoid danger.

Third, it should be cleaned in time.

Many friends in the use of the thermos cup, in addition to the new thermos cup just bought back before use will be carefully cleaned, in the future use of the rarely carefully cleaned, thinking that usually just decorate the white water, will not be dirty, such an idea is very wrong. There are a lot of hygienic dead ends in the thermos cup, which can not be cleaned up by rinsing at will, such as the gap in the lid of the cup, under the sealing rubber ring, which is easy to hide dirt and dirt, although the cup is filled with boiled water, but the bacteria that fall when the water cup is switched on and off are easy to multiply more in a warm and humid environment, if not cleaned up in time, it is easy to pollute the water in the cup, so it is necessary to carefully clean the thermos cup in a timely and regular manner, so as to make yourself drink more clean and hygienic.

Fourth, pay attention to the temperature.

Some good thermos cups keep warm for up to 12 hours, and the heat preservation effect is very good. This requires everyone to pay attention to the temperature in the thermos cup when using it. If you pour hot water initially, be careful when drinking it again to avoid burning your mouth and tongue.

In addition, if the quality of the thermos cup is more general, the sealing rubber ring is thin, and the sealing effect is not good, try not to fill it with too hot water, although the heat preservation time of the water may become shorter, but the sealing effect is not good, the hot water in the cup is easy to leak, and it will be accidentally scalded if you carry it.

Before use, the inner tank should be cleaned, first rinsed with warm water to prevent the temperature difference from bursting, and then filled with boiling water to cover the cork and soak for 12 hours, observe that it can keep warm, there is no abnormality and leakage, and the water can be used normally if the tank is re-canned, and there is a piece of paper (certificate) in the gall do not forget to take it out.

The first time you add water to the thermos cup, it should not be too full, so as not to burn the boiling water when you tighten the lid of the cup. The first time you use a thermos cup, its thermal insulation performance must be very good, so be careful when drinking hot drinks with a thermos cup, and don't make a mistake in judgment and get burned.

At the same time, pour boiling water into the thermos cup and tighten the cork or cup lid clockwise for 2-3 minutes, then touch the outer surface of the cup body with your hands.

After adding water to the cup, tighten the cork and lid in a clockwise direction, and place the cup flat on the table, so that there should be no water leakage; The screwing of the lid and the mouth of the cup should be flexible, and there is no gap, so that the cup is better sealed.

The 304 and 316 stainless steel mugs are safe to use.

The qualified thermos cup liner is made of food-grade stainless steel 304 and 316 materials, 316 material is lighter, more resistant to high temperatures, and more corrosion-resistant, but the cost is also higher. Straws, seals and accessories are generally made of Tritan, PP and food-grade silicone, which are safe and usable.

304 is a versatile stainless steel that is widely used in equipment and parts that require good overall properties (corrosion resistance and formability). In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard.

The glass thermos cup is not unsafe, 1. It is safe to drink cold water in the glass, and it is not safe to drink hot water. 2. The first choice for drinking water is a healthy drinking water that has always been advocated, but compared with ordinary glass, tempered glasses have the possibility of self-explosion, because nickel sulfide components that cannot be found by the naked eye are mixed in the manufacturing process of tempered glasses.

3. This kind of nickel sulfide will cause the tempered glass to expand greatly that does not match the glass under the temperature change of the surrounding environment, resulting in the phenomenon of glass self-explosion flyer, so the tempered glass should not use boiling water.

Heat resistance and self-explosion are inherent properties, or rather defects, of tempered glasses. No matter how thick the glass is, there is a phenomenon of self-explosion, which is a normal phenomenon. For this reason, if you want to boil water to make tea, try to choose a glass of ordinary material, and the tempered glass must not be heated in the microwave.

When buying glasses, be sure to pay attention to the following:

1. Check whether the product identification is complete, including the manufacturer's name, address, product name, model, safety warnings, etc., and do not buy three-no products.

2. Observe whether the glass has bubbles and impurities from the appearance, and it is best not to buy cups with bubbles or impurities.

3. See whether the object is out of shape through the cup, if the object is seriously out of shape through the cup, it is not recommended to buy.

4. Before use, read the product manual and warning label information in detail, especially the maximum use temperature of ordinary glass water utensils, the type of liquid contained in it, etc., to avoid burns or scratches and other injuries.

The thermos cup insulated lunch box is generally a container made of double-layer plastic or stainless steel plus a vacuum layer or thermal insulation layer, with a lid on the top and a tight seal, and the vacuum layer or thermal insulation layer can delay the heat dissipation of the meals installed inside, so as to achieve the purpose of heat preservation. The insulated lunch box is developed from a thermos flask, and the principle of thermal insulation is the same as that of a thermos flask. There are three ways in which heat can be propagated:

Radiation, convection, and transfer. The silver liner in the thermos cup can reflect the radiation of heat, and the vacuum layer or thermal insulation layer of the cup body can block the transfer of heat.

And what problems should I pay attention to when using insulated lunch boxes? Before use, check whether the rated voltage marked on the nameplate of the body is consistent with the voltage you use. Please use a power supply with grounding protection to ensure the safety of the gods.

Practical objects should be placed on a stable platform and out of the reach of children. Do not press the power switch too hard to prevent damage to the power switch.

Also, since someone asked which brand of insulated lunch box is good, it seems that everyone still has a certain recognition of a good brand. Indeed, the quality of the brand is largely related to the quality of the product.
