In the winter season, hot water bags are now essential for many people in winter, also known as "warm artifacts." Hot water bags are bag-shaped, metal shell, ceramic, just plug in the power, charge for a few minutes, you can heat after the power to buy carefully and use hot water bags. However, the current electric hand warmer on the market lacks uniform quality standards, product quality is uneven, and safety concerns are worrying. Then, hot water bottle which is better? Well hot water bottle what material? Let's take a look with Xiaobian.
Which kind of hot water bottle is good?
1. Touch the material, to choose the hot wire (tube) type hot water bottle, through the hand to identify, if you feel the inside is a small stick, it is electrode type. If you feel in the bottom of the hot water bottle can touch the net-like object is a hot wire hot-water bottle, if you can touch the inside of a larger U-shaped, arc-shaped pipe is electric heating tube type electric hot water bottle.
2. Look at the signs. Look for signs on the packaging of electric hot water bags that have no goods, such as trademarks, certifications, precautions, certification marks, manufacturer's names, etc. Don't buy “three non-products†at will, so as to avoid damage to rights and interests.
3. Many comparisons, consumers should make more comparisons at the time of purchase. Because electric wire (tube) type electric hot water bags are expensive to manufacture, the ex-factory price is mostly between 25 yuan and 30 yuan. If the price of the product is lower than this price, it is necessary. Choose carefully. In addition, consumers must keep shopping vouchers after purchasing electric hot water bags in order to protect their rights.
Hot water bag what material is good?
1. Fabrics. At present, there are several types of fabrics for electric hot water bags on the market: PVC materials, mercerized cloth materials, and flannel materials: PVC materials are hard to handle, easy to age, have a firm degree, are hot after heating, and belong to the low-end materials; the mercerized cloth materials are soft and firm. High degree, moderate hot degree after heating, belonging to the middle end; flannel material feels comfortable, not hot after heating, good firmness, is the best quality fabric.
2. Kind. At present, the electric hot water bags on the market are divided into electric hot wire type electric hot water bags and electrode type electric hot water bags. The electrode type electric hot water bottle is very unsafe. It depends on the heating of the electrode. The internal solution is charged during the heating process. The safety depends on the external temperature controller and the human eye. This type of electric hot water bottle has actually been banned by the country. Electric wire type and electric box is actually a principle, but it is heating the water this heat than the medium. Because of the full insulation and temperature control, it is much safer than electrode type.
3. Power supply. When purchasing the electric heating hot water bottle, it depends on whether the power cord is intact, and then see if the power cord interface on the electric heating bag is cracked or other safety hazards, such as whether there are three contact holes in the power cord interface. The three metal columns in the metal tabs and connectors are not the same length.
4. Brand. Nowadays, there are many types of electric hot water bottle brands, and the quality varies greatly. When purchasing, they must go to regular shopping malls and supermarkets to purchase products that have relatively complete information such as factory name, production license, use instructions, and qualification certificates.
Electric hot water bag explosion problem
1. Product quality: The manufacturers of electric hot water bags on the market are currently mixed, and the quality of electric hot water bags is also uneven. The main problems that exist are the "structure" of the safety, the input power and current, the non-compliance of the overvoltage protection device, and the inconsistent power and nominal of the electric hot water bag. According to national standards, electric hot water bags must be fitted with overpressure protection devices. Some companies have failed to install overvoltage protection devices because of the lack of technology, which results in explosions when the power is turned on. Some products keep rising in temperature when they are charged, and they also easily cause heating expansion and explosion. Moreover, although these products are marked with “execution standards†on the outer packaging, this is only a means by which some manufacturers deceive consumers.
2. Although the electric hot water bottle can bring warmth to everyone, there are some potential safety hazards due to poor use. In this remind everyone to pay attention to the use of electric hot water bags:
(1) Before power on, first check whether there is any water on the hot water bottle socket. To ensure safety, ensure that the socket is dry. Then insert the electric hot water bottle plug first, then plug in the power plug to power on. After the power is turned on, unplug the power plug and then remove the electric hot water bottle plug.
(2) In the process of energization, the electric hot water bottle should not be held in the arms, and it is forbidden to beat or sit on it so as not to cause leakage of liquid. It is best not to leave the site under power-on condition. Observe the indicator light. After the indicator light goes out, it indicates that the power-on heat storage is over. Generally charge 5-10 minutes.
(3) It is forbidden to heat the electric hot water bottle with boiled or roasted, if the liquid in the electric hot water bag leaks, it shall be immediately stopped.
(4) It is forbidden to use while charging, just fill the hot water bottle, do not directly close to the skin, to prevent burns caused by high temperatures.
(5) Pay attention to the water temperature not to be too hot, the time should not be too long, the hot water bottle should be placed at the foot of 10 cm, and not on the feet; it is best to sleep in the quilt before going to bed.
(6) When using the charging hot water bottle, the plastic hole cover on the bag should be opened periodically to remove the air.
(7) The life of the electric hot water bottle is generally about one or two years. Even if the electric water bottle is of good quality, the internal lines and structures are aging during use, and there are hidden dangers of malfunction and short circuit. If it exceeds this time, it is better to replace it.
Conclusion: The relevant information on what kind of hot water bottle is good and what kind of hot water bottle material is good is introduced here. I hope this article will be helpful to everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom. We will answer your questions as soon as possible.
