As the weather continues to cool down after winter, charging hot water bottles, hand warmers and other heating “gadgets” have ushered in the hot season, because of their diverse styles and cute appearance, many adults and teenagers have bought them.
However, what is the safety issue of charging hot water bottles and hand warmers? Ms. Li, a citizen of Zhengzhou, bought a rechargeable hot water bottle from the Internet to heat up, but as a result, an explosion occurred on the first charge, but fortunately the hot water splashed by the explosion did not hurt anyone. At the same time, many members of the public reported that the rechargeable hot water bottles sold in the market, hand warmers without outer packaging, lack of safety reminder signs, and poor workmanship of charging cables.
In this regard, the reporter of Dahe News and Dahe client visited and investigated the hot water bottles and hand warmers sold on the market.
Narration: Bought online to charge a hot water bottle for heating, the first charge exploded
On the morning of November 25, the reporter of Dahe Daily met Ms. Li, a citizen near the intersection of Agricultural Road and Wenhua Road in Zhengzhou City. According to Ms. Li, after the weather began to get colder because there was no heating in her home, she bought a charging hot water bottle from an online shopping platform during Double 11 half a month ago to sleep at night to warm up. But what she didn’t expect was that a week ago, after she received the hot water bottle courier, the first time she charged the hot water bottle exploded.
“I heard a ‘bang’ from the bedroom, it wasn’t loud, so I didn’t care, and when I went back to the bedroom, I found that the hot water bottle had exploded, and the liquid inside wet the bedding on the bed!” Ms. Li said that she put the hot water bottle on the bed in the bedroom to charge, originally thinking that after charging it, she would put it directly into the bed, so that she could sleep well after washing, but when she entered the bedroom to check whether the hot water bottle was charged, she found that the hot water bottle had exploded, and the bedding on the bed was also wet by the liquid splashed by the explosion, and she took a lot of effort to change the futon.
Ms. Li said that the original price of the hot water bottle she bought was more than 40 yuan, and the preferential price on Double 11 was less than 20 yuan. After the hot water bottle exploded, she immediately contacted the online seller, who directly refunded and sincerely apologized, plus she was not injured, so she did not pursue further. But to this day, she still has palpitations in her heart, and she does not dare to use the rechargeable hot water bottle. “Fortunately, I was not lying in bed at that time, and the explosion of the hot water bottle did not cause hidden dangers such as short circuits in the wires, otherwise I really didn’t dare to think about it!”
In addition, during the interview, in addition to what happened to Ms. Li, many citizens reported to reporters that when they bought rechargeable hot water bottles and hand warmers (no liquid, you can carry them with you) in the market, they found that many rechargeable hot water bottles and hand warmers not only had no packaging, but also lacked safety reminder signs, and even some charging cables were poorly made, and they were also very worried about this.
Visit: Hot water bottles and hand warmers are hot in the market, and the certificate cannot be found, and the “source is unknown”
In order to understand the situation of rechargeable hot water bottles and hand warmers sold in the market. On the morning of November 25 and 26, Dahe Daily and Dahe client reporters visited many street stores in Zhengzhou and wholesale markets around railway stations. On the shelves of these street stores and wholesale market wholesale stores, the reporter saw that a large number of charging hot water bottles and a variety of rechargeable hand warmers were on sale. Among them, the price of rechargeable hot water bottles ranges from fifteen yuan to forty or fifty yuan, and most of the appearance is made into a “plush toy” style, with a cute and attractive appearance; The price of charging hand warmers ranges from 70 or 80 yuan to more than 100 yuan, its body is small and exquisite, not only has the function of charging treasure, but also can be carried around; However, the quality of both is “uneven”!
Hot water bottle: the same “core” under different appearances, and the “certificate” cannot be found in the packaging box
During the visit, the reporter saw in a number of street stores and wholesale stores that different styles of charging hot water bottles were neatly placed on the shelves, including not only the simplest single rechargeable hot water bottle, but also many rechargeable hot water bottles wrapped in “plush toys”. According to the owner of a store that sells rechargeable hot water bottles, don’t look at the appearance of these hot water bottles is different, but the “core” inside is the same, a brand, but the wrapped “plush toys” are different, so the price is not the same.
At the same time, the reporter also found that in addition to most of the branded charging hot water bottles embroidered with charging safety tips on the edge, a small number of hot water bottles are only embroidered with an indiscernible name, without any safety tips, and many cannot see the outer packaging. When the reporter asked a wholesale shop owner whether the hot water bottle he sold had outer packaging, the owner immediately took out an unopened hot water bottle and said that they had unpacked the sample box, and there were all packaging boxes. But when the reporter found that there were only hot water bottles and charging cables in the box, and there were no instructions, certificates and other paper instructions, and when the owner asked again, the shopkeeper’s smile immediately cooled down, saying that they were factory direct sales, and if they didn’t want to buy, they could leave.
Subsequently, the reporter saw in a number of wholesale stores that there were many hot water bottles in the packaging box, only warm water bags and charging cables, no instructions, certificates, and no 3C certification and other marks on the outer packaging. Shopkeepers or associates in these wholesale stores say their hot water bottles sell very well and that it is safe to automatically cut off when fully charged.
In addition, during the observation, the reporter also saw that in a wholesale store that sells rechargeable hot water bottles, a clerk packed the rechargeable hot water bottles stacked in a large box into freshly folded packaging boxes, with dozens of bundles of charging cables waiting for boxing at its feet, and a stack of stacked packaging boxes next to it. During this period, the reporter never saw the paper items such as manuals and certificates of conformity.
Hand warmer: “On the list” charging treasure seems practical, the packaging is in English “unknown”
During the visit, in addition to the hot-selling rechargeable hot water bottles, the reporter also saw that seven handwarmers with exquisite appearance, small physique, and easy to carry were also on sale. According to one shopkeeper, their hand warmer sells very well because it not only heats up and heats up, but also can be used as a power bank, not only by many adults, but also by many students.
However, when the reporter checked these hand warmers in detail through visits, he found that the outer packaging of four of them was all English logos, without any information such as the manufacturer’s address, and there was no information on the instructions in the box, and there was no certificate of conformity in the box.
In this regard, the reporter immediately asked the clerk in a wholesale store, why are these hand warmers packaged in English and there is no manufacturer information? When asked, the clerk couldn’t answer, only saying that the boss bought the goods from the Internet, and he didn’t know.
Investigation: The reporter compared the purchase, and the professionals found that it was a product banned by the state
In order to understand the safety of rechargeable hot water bottles, the reporter purchased two rechargeable hot water bottles from wholesale markets and street stores at a price of 20 yuan and 35 yuan respectively, and consulted Mr. Chen, who has been engaged in the electrical maintenance industry in Zhengzhou for many years. As a result, Mr. Chen picked up the 20 yuan rechargeable hot water bottle bought from the wholesale market and touched it with his hand, and told reporters that this was an electrode-type hot water bottle that the state had banned the production and sale many years ago.
Mr. Chen said that as far as he knows, the heating method of the charging hot water bottle is divided into heating wire and electrode type. Among them, the heating wire is not in direct contact with the liquid for heating, and the safety is relatively high. The electrode type is directly to the liquid as the conductor, there are two metal rods, that is, positive and negative poles, because its positive and negative poles heating is directly in contact with the liquid, if there is no temperature control device, charging will appear has been expanding, there is a risk of explosion, so it was banned from production and sales by the state many years ago.
“‘The production cost of electrode type hot water bottles is extremely low, one should be less than 10 yuan, if you encounter bad merchants with some inferior electrodes, it will be cheaper, but the risk of explosion will also be greater.'” Mr. Chen said that electrode hot water bottles have been banned from production and sales by the state, and now the electrode hot water bottles sold on the market are all three-nil products.
In this regard, the reporter found through Internet search that in November 2010, the state officially implemented the “Special Requirements for Safe Heat Storage Electric Hand Warmers for Household and Similar Electrical Appliances”, which made relevant specific provisions on the load-bearing capacity, temperature rise, power outage, and sealing degree of electric hand warmers. Among them, the production and sales are prohibited because the electrode hand warmer does not meet the requirements of the national standard and is prone to leakage and bursting hazards.
Reminder: When purchasing a rechargeable hot water bottle, you can touch it first, and the hand warmer can be protected by brand
Since electrode hot water bottles, which have been banned from sale by the state for 9 years, are still hot selling in the market, how to choose a rechargeable hot water bottle? In the face of the hand warmer in English on the outer packaging, how should the public choose?
In this regard, Mr. Chen introduced that if you want to identify whether the hot water bottle is an electrode hot water bottle, it is actually very simple, as long as you touch it with your hand, if you feel that there are two cylindrical tubes in the charging place of the hot water bottle, it is an electrode hot water bottle. If you feel that there is a large U-shaped or circular arc-shaped tube in the hot water bottle, it should be a heating wire type hot water bottle, which is relatively safe. In addition, when using a hot water bottle, always check whether it is leaking, and if you find water leakage, do not continue to use it to avoid potential safety hazards.
“Compared with the rechargeable hot water bottle, the hand warmer is a new product, and its interior not only needs to be heated, but also has a storage battery, and the relative safety requirements are higher, so you must pay more attention when purchasing!” Mr. Chen said that he suggested that when buying a charging hand warmer, you must go to supermarkets and shopping malls to buy brand products produced by regular companies, so that the products not only have after-sales guarantees, but also have higher safety.
Link: Disassembly experiment, there are only two cylindrical metals in the 20 yuan hot water bottle, and the charging cable has no power off device
In order to understand the situation that Mr. Chen judged. After the interview, the reporter found scissors and other tools, and carried out a disassembly experiment on the rechargeable hot water bottle bought for 20 yuan. When the reporter used scissors to cut the hot water bottle and poured out the yellowing and discolored liquid inside, he turned over two cylindrical metal heads about one centimeter long that had been blackened, with a strong rust smell above them, and a device with aluminum foil in the middle that seemed to control temperature. The reporter took a picture of the internal structure of the hot water bottle he saw and sent it to Mr. Chen. Mr. Chen said that he was 100% sure that this was the electrode type hot water bottle that the state banned from producing and selling.
In addition, the reporter also opened the screw on the plug of the charging cable, which only has a display light and a link display lamp transistor, not only no fuse, but also did not see the automatic power off device that the salesman said.
