When the cold wave came, many netizens started "heating artifact", such as foot warmer, heating cushion, hand warmer, heating mouse pad, etc. What is the effect of these "heating artifacts"? Is it safe? Recently, Shanghai Consumer Protection Commission purchased 11 "heating artifacts" for actual measurement. Heater: pay attention to product noise and applicable area Shanghai Consumer Protection Commission has purchased three types of heater products, one of which can only be used on the table, and the other two can be placed on the table or used for heating the whole room. Among them, the desktop heater is equipped with three gears of "warm air", "hot air" and "cold air", and is also equipped with mobile phone wireless charging function. After the trial, the Shanghai Consumer Protection Commission found that the temperature difference between the "hot air" gear and the "warm air" gear was small, the "hot air" gear was stronger than the wind, and the hot air sound was louder. Compared with heaters using heating wires, Shanghai Consumer Protection Commission has also purchased popular heaters using graphene heating materials. The experience shows that there is little difference in heating effect between heating wire and graphene electric heater products, but the products using graphene heating material have less noise, but the price will be more expensive. Shanghai Consumer Protection Commission suggested that matching heater products should be selected according to the area of the room. In addition, the air outlet temperature of heater products is relatively high. Pay attention not to touch to avoid hot hands. Foot warmer: the one with power-off protection is preferred Shanghai Consumer Protection Commission has purchased five foot warming products, of which two use graphene heating materials, two are traditional heating wire foot warmers, and the other one is electric water bag foot warming products. The experience found that two foot warming products are equipped with timed power-off protection, which is safer to use. As the foot warming products are used close to the body, Shanghai Consumer Protection Commission tested the temperature of five foot warming products at the highest gear, and the temperature of four products is between 50 ℃ and 70 ℃. Among them, the top panel of one product reached 127 ℃. In this regard, Shanghai Consumer Protection Commission said that although this product has anti dumping power-off protection, it is better to be careful when getting up and walking. The gear of heating cushion is not marked, and the smell of heating mouse pad is obvious After purchasing, Shanghai Consumer Protection Commission found that the gear of heating cushion was not marked. When I first used it, I smelled obvious plastic smell. In addition, the purchased mouse pad also has an obvious plastic smell when it is opened for the first time, and the plastic smell is greater after charging and heating up. Therefore, the Shanghai Consumer Protection Commission suggested that before using plastic electric heating products, they should be blown outside to disperse the smell. Finally, with regard to whether electric heating products need 3C certification or not, Shanghai Consumer Protection Commission said that indoor heater products need CCC certification, that is, "China Compulsory Certification", and 3C certification marks can be found on the appearance of goods. It is suggested that before placing an order to buy heating products, first consult the customer service about whether the products have 3C certification number, and log in to the official website of "China Quality Certification Center" to query the corresponding filing information.
