1. Development promotion
With the rapid development of science and technology, people's concept of clothing and dress has also changed. Clothing is no longer limited to the basic functions of keeping decent and beautiful, and gradually began to develop in the direction of technology and intelligence. At the same time, human beings are involved in more and more fields, and their exposure to natural and man-made environments is more harsh and diverse. Therefore, people's demand for the functionality, comfort and safety of clothing has increased, and the electric heating jacket was born on demand. The electric heating jacket can add functions such as music, positioning, and management of health data as needed, but the more mature function is the heating function.
2. Keep warm
In the cold winter, there are many special types of jobs. For these jobs, people have to work in low-temperature environments, such as freezer workers, traffic controllers, security guards, drivers driving motor vehicles, troops at border posts, military police and field explorers, polar Investigators, divers, etc., all face the same problem: keeping out the cold and keeping warm. The clothing itself does not generate heat, so it is extremely important to develop an electric warming jacket that can automatically provide a heat source. The electric heating jacket can continue to warm up the human body, making people feel warm all the time. However, there are some issues that people are concerned about, such as whether the thermal performance of an electric heating jacket will make the human body feel uncomfortable, and whether it is consistent with the principles of human physiology and hygiene, which has led to discussions on the thermal performance of the electric heating jacket.
1. Electric heating jacket
Electric heating jacket is a general term for clothing that is composed of clothing's main body, heating element, power supply, temperature control system, protection device, etc. The heating element is very important to the composition of the electric heating suit and is usually placed in some sensitive parts such as the front chest, back, waist, and abdomen of the human body. When working, the electric heating jacket first heats the important parts of the body to keep warm and then disperses the heat to the whole body.
2. Heating material of the electric heating jacket
There are three main types of heating materials for electric heating jackets: metal heating materials, carbon fiber heating materials, and electric heating films. At present, the most widely used is the use of electric heating wire heating or carbon fiber heating wire. In addition, a heating cloth made of conductive rubber, graphite, carbon polymer, etc. is used as an electric heating element. The power supply is used to power the electrically heated garment, and a voltage below 12 V is safe.
3. Temperature control system of electric heating jacket
The temperature control system automatically controls whether the heating element runs through sensors to detect changes in the temperature of human skin or under clothing. The protection device can automatically turn off the power supply when the circuit in the electric heating suit suddenly fails, so as to protect personal safety. The advantage of an electric heating jacket is that the temperature can be controlled, specific parts of the clothing can be heated at a fixed point, the performance is relatively stable, and it can be reused. Its disadvantage is that the battery is difficult to handle because the big battery with a large capacity is hard to carry while the portable battery has a small capacity and cannot maintain heat for a long time.
