Are there any safety hazards after long-term use of digital kettles?

In modern families, digital kettles have gradually become an indispensable electrical product in daily life. It not only meets the needs of fast heating of drinking water, but also provides multiple functions such as temperature regulation and heat preservation, bringing many conveniences. However, with the extension of the use time, digital kettles may also face some safety hazards, especially in the case of improper daily maintenance or high frequency of use.
During long-term use, the heating element of the digital kettle may reduce the working efficiency due to scale accumulation. Scale adheres to the heating area for a long time, which not only prolongs the heating time, but also may cause local overheating, thus bringing certain safety risks. Especially in the absence of regular cleaning, the scale problem is often ignored and gradually accumulates to the extent that it affects the safety of use. In addition, excessive local temperature during heating may cause deformation of the kettle body, aging of internal components and even circuit short circuit.
Digital kettles rely on electronic control systems for temperature management and automatic power-off protection. After long-term use, these electronic components such as temperature control sensors, circuit boards, relays, etc. may reduce performance due to aging, moisture or high temperature environment. Once the temperature control system fails, it may not be able to accurately judge the water temperature, thus losing the function of power-off protection. Continuing heating may cause the risk of dry burning. In severe cases, it may even cause the shell to melt and smoke, threatening the user's safety.
The power cord and plug of the digital kettle should not be ignored. In the case of frequent plugging and unplugging or wire pulling, problems such as loose plugs and poor wire contact are prone to occur. If these problems are not handled in time, they may cause local heating, arc discharge and other phenomena, increasing the risk of electricity use. In addition, if there is water inflow or dust accumulation in the connection area between the socket and the base of the kettle, it may also cause leakage hazards.
The material of the kettle body is also a factor that affects the safety of long-term use. Some products may experience aging of the plastic part, surface shedding, etc. during high temperature or repeated heating, and even produce harmful gases or trace amounts of harmful substances under extreme conditions. If the material selection or manufacturing process is not up to standard, the probability of this problem will be higher.
In order to reduce the above safety hazards, users should clean the digital kettle regularly, especially remove scale, and keep the heating part clean and unobstructed. In addition, avoid dry burning in daily use and ensure that there is always enough water in the kettle. For the power cord, avoid frequent twisting or pulling, and replace it immediately if any abnormality is found. If the kettle has inaccurate temperature control, automatic power-off failure, or abnormally prolonged heating time, stop using it immediately and check it or contact after-sales service.
