Electric blanket: affordable but defective
In the market of heating products for beds, electric blankets are still playing a leading role, with prices ranging from tens to more than 100 yuan, making it easy for most consumers to accept. However, some consumers found that there were unsafe factors in electric blankets. Although some brands of electric blankets claim that they are not afraid of water, it is still unsafe to get wet because the electric heating wire is hot.
"Electric blanket also has electromagnetic radiation and skin dryness and other hidden dangers." Doctors say that every winter, some patients with dermatitis caused by electric blankets will be treated. Especially for the elderly, their skin is dry. Using electric blanket for a long time will make the body lose too much water and aggravate dryness. It will easily lead to skin allergy, itching, dry throat, constipation knot and so on. In addition, the electric blanket will produce electromagnetic radiation after electrification, which will have a certain impact on the human blood system, endocrine system and so on.
In order to prevent harm to human body, doctors remind people with respiratory diseases, cardiovascular and cerebrovascular diseases or allergic constitution that it is best to use fewer or no electric blankets.
Plumbing blanket: more comfortable and safer to use
A new type of bed heating equipment, water heating blanket (spring heating), is seen on the market. "Its principle is similar to the floor heating of a building. A water pipeline in a cotton blanket can be connected with electricity." A distributor said that the water heating blanket consists of two parts: the main engine and blanket surface. The main engine includes heating, temperature control system and circulation system. Its function is to heat water to a set temperature and then circulate it to the blanket body. Material used for blanket is quite different. Considering the cost, we usually use ordinary electric blanket with felt, which will feel a little hard when sleeping. High-grade blanket uses memory cotton, also known as zero-pressure sponge. This material has special viscoelastic properties and can provide the most uniform supporting force. It's softer and more comfortable to use, but it's more expensive.
"The water heating blanket avoids the defects of strong radiation, drying and leakage risk of the electric heating blanket, and is safer and more comfortable to use." Industry insiders said that users only need to connect the blanket body and the main engine, add 400 ml of water to the main engine, and then use electricity; if there are children in the home, they can also clean the bed with water directly, without affecting the use effect; safety is also very assured, when there is no water, the machine will automatically alarm, will not cause fire; After winter, it can be folded and collected by draining its internal moisture.
