Plumbing radiator-Uniform heat dissipation, comfortable and aesthetic appearance, the bathroom heater is what we frequently appellate a water heater, that is, the circulating water is heated by a wall-hung furnace or a boiler, and then connected to the heater through a pipeline, and finally outputs the appropriate temperature through the heater to form an interior temperature difference, and…

Also known as stand fan, electric stand fan is household appliance that uses an electric motor to drive the fan blades to rotate, thereby accelerating the circulation of air. Mainly used for cooling and relieving heat and circulating air, electric stand fan is widely used in homes, classrooms, offices, shops, hospitals and hotels. Common household electric fans…

The following heaters with several heating principles are very similar in appearance, slightly different in internal structure, and basically the same in use method. Electric wire heaters, quartz tube heaters and metal tube heaters convert electric heat into thermal energy. When the heating medium generates enough high temperature, the heat will be diffused by the reflecting panel….

Startup performance – Check carefully whether the fan cover and fan blades are obviously deformed. When turning the fan blades, it should be brisk and flexible, and should not always stop at the same position. The starting performance is an important quality indicator of the fan. During the inspection, when the rated voltage of the power supply…

Manufacturing active oxygen – Negative oxygen ions can effectively activate oxygen molecules in the air, making them more active and more easily absorbed by the human body, effectively preventing “air conditioning disease”. In addition, negative ions can enhance the moisture retention of the hair. Generally, the surface of the hair is in the shape of scattered fish scales,…

PM2.5 refers to particulate matter with an aerodynamic equivalent diameter of less than or equal to 2.5 microns, which are solid and liquid particles suspended in the air. With the diameter less than 1/20 of a human hair, PM2.5 is the main reason for the formation of haze weather, which the main source is the residues…

Electronic thermostat – As known as temperature control switch, temperature protector and temperature control equipment, the thermostat is an automatic control element, which will occurs the physical deformation inside the switch to generate a series of on or off instructions according to the temperature change of the working environment.The temperature is transmitted to the temperature controller…

Adjustable thermostat – As a temperature sensing element, the temperature control switch is a switch with a bimetallic strip. When the heater is working normally, the bimetal is in a free state and the contacts are in a closed state; When the temperature reaches the operating temperature of the heater, the bimetallic element is heated to produce internal…

The PTC heater is composed of PTC ceramic heating element and aluminum tube. Constant temperature heating PTC thermistor has constant temperature heating characteristics, which the principle is that after the PTC thermistor is powered on, the self-heating temperature will make the resistance value enter the transition zone, and the surface temperature of the PTC thermistor…
