　　The role of temperature fuse in vacuum cleaner

　　Temperature fuses play an important role in circuit protection in vacuum cleaners. A vacuum cleaner is a household appliance typically equipped with an electric motor to generate suction. During use, the electric motor may overheat due to prolonged continuous operation or other abnormal conditions. At this point, the temperature fuse serves as an important safety device to prevent damage to the motor and ensure the safety performance of the vacuum cleaner.

　　A temperature fuse is a specially designed thermal element that contains a thermal sensitive material inside, and its resistance characteristics change with temperature. When the temperature reaches or exceeds the rated triggering temperature of the fuse, the fuse will quickly open the circuit and cut off the current. The purpose of doing this is to prevent the temperature of the motor from further increasing, in order to avoid the occurrence of dangerous situations such as motor damage or even fire caused by overheating.

　　The main functions of temperature fuses in vacuum cleaners are as follows:

　　Overheating protection: The temperature fuse can sense changes in the temperature of the motor. When the temperature of the motor rises abnormally, the fuse will quickly cut off the circuit to prevent the motor from overheating. This can protect the windings and other sensitive components inside the motor, avoiding damage or failure caused by overheating.

　　Safety protection: The function of the temperature fuse is to ensure the safe and stable operation of the vacuum cleaner's electrical system. When the motor overheats, if there is no fuse to quickly cut off the current, it may cause serious safety issues such as circuit failure, circuit board damage, and even fire. The presence of temperature fuses can effectively avoid these potential hazards.

　　Extended service life: By using temperature fuses, the temperature rise of the motor can be timely limited to prevent damage from overheating. This can extend the service life of the electric motor, improve the overall performance and durability of the vacuum cleaner.

　　It should be noted that if the temperature fuse is triggered multiple times or too frequently, it may be due to abnormal temperature rise caused by other issues. At this time, it is necessary to promptly check the operating environment, circuit connections, motor status, etc. of the vacuum cleaner, identify and solve potential fault causes, to ensure the normal operation and safety performance of the vacuum cleaner.
