The far-infrared electric heater is an ideal radiant heater in winter. It is suitable for heating the human body in a room with poor heat preservation conditions, no need to heat the whole space and high fluidity. It is a kind of close-body heating equipment, and the effective heating distance is generally It is about 2m, and if it exceeds 3m, its thermal energy will be greatly reduced.
The far-infrared heater is mainly composed of three parts: electric heating element, reflecting device and electrical system. The components are generally composed of a metal tube element and a milky quartz tube element, and the opalescent quartz tube element is further divided into a vertical type and a horizontal type; the reflecting means is made of an aluminum plate which has been subjected to electrolytic polishing and anodizing, and the advantage is that the reflection is Good performance, corrosion resistance, etc., electrical systems are generally divided into two types, one is simple, one is a temperature-controlled automatic power-off device and the electric heater collapses automatic disconnect device. The far-infrared heater radiates and reflects heat from the far-infrared light emitted from the quartz tube through the parabolic reflector, so that the thermal efficiency is high and the energy saving effect is obvious.
The ear-hook earphone refers to a kind of earphone that is added with an ear-hook on the side of the earphone for convenient use. Different from in-ear earphones, ear-hook earphones are a type of earphones and earbuds that are divided according to how they are worn. Design principle: the connection between the two units of the earphone and the wearing of the fixed beam can be canceled, with a beautiful hook to make it hang on the ear.
Advantages:
1: The way of ear hooks ensures the reliability of the user's wearing. In the design of earplugs, the unit is often enlarged to meet the needs of sound quality.
2: The design of the earhook fully demonstrates the design capabilities of the earphone manufacturer, from the design to the reliability of the wearing of the ergonomic design.
