What are the purchasing skills of warm hand treasure? What is the power of warm hand treasure
4hw.org: the weather is getting colder and colder every day. Warm hands have become the necessary heating supplies for many people, especially for the students in school. Generally, high-power electrical appliances are not allowed in dormitories. How much power is warm hands? Is it high-power electrical appliances? Let's take a look at it together!
I. power of warm hand treasure
Different brands have different power. Generally speaking, the power range is 50W ~ 500W, the voltage is 220V, and the frequency is 50Hz.
2. Will warm hand treasure explode
If warm hand treasure is a miscellaneous brand, the quality of its electric furnace wire is poor and the rated power is too high, which may explode in charging and use. Therefore, when we purchase warm hand treasure, we'd better purchase and ask for a small ticket from a regular business. In addition, the warm hand treasure needs to be placed flat when charging to prevent the hot wire from burning the bag. When charging, do not touch it, do not put it on the ground for charging, to prevent damage due to too large temperature difference. If there is any liquid leaking out or abnormal sound heard during charging, it must not be used.
According to experts, warm hands on the market can be divided into two types: liquid filled type and round cake type. Because it's like a hot water bag, the liquid filled hand warmer is very popular. Because of different heating devices, the liquid filled warm hand treasure can be divided into two types: electrode type and heating wire. In the current market, the electrode type warm hand treasure accounts for the vast majority. According to the national standard "safety of household and similar electrical appliances" issued in 2005, "electrodes shall not be used for heating liquid". As there is no product standard for warming hand treasure at present, strictly speaking, warming hand treasure heated by electrodes is unqualified.
Although all of them are conducted by liquid, the water in the warm-up handlebar with heating wire is not electrified, while the water in the electrode type warm-up handlebar is electrified. If the thickness of the insulating layer of the warm-up handlebar is not enough, or the sealing port is not strict, water leakage may occur.
According to the head of an enterprise that produces warm handlebars, the production cost of warm handlebars using hair heating wires is more than half of that using electric heating wires. The retail price of the former is about 50 yuan, and the retail price of the latter is 120 yuan. The way to distinguish the two is to knead the warming hand treasure by hand. The former can feel that there are two electrodes in it, and the latter can knead the mesh heating wire inside.
III. how to purchase warm hand treasure
Warm hand treasure purchase and brand recognition: the whole process from design to processing of famous brand products produced by regular large factories is rigorous, and the quality of products is relatively high, while the quality and processing process of warm hand treasure products produced by small workshops are not standardized, and the risk factor is large.
Warm hand treasure appearance: whether the product is damaged after collision? Whether the workmanship is fine, and whether the stitches at the seams are fine, even and intact.
Purchase and check the safety of warm hand treasure: in addition to checking whether the circuit is in good condition, pay attention to whether the material of warm hand treasure is fire-resistant and heat preservation material, and whether the furnace wire used is a high-quality brand product.
