Description

Technical Field

[0001] This utility model relates to the field of electric heater protection technology, and in particular to a protective device for electric heaters. Background Technology

[0002] Electric heaters, as a common heating device, provide warmth to people during the cold season and are widely used in homes, offices, and other places. However, in actual use, electric heaters face several potential risks, requiring effective protective measures to ensure their safe operation and the safety of users. First, electric heaters have high surface temperatures during operation, especially some heat dissipation components, which can easily burn people who accidentally come into contact with them, particularly children and pets. Their awareness and ability to prevent danger are weak, making them more likely to accidentally touch the heater, and burns are not uncommon. Second, electric heaters may tip over due to external impacts during use. Once tipped over, it may damage the heater itself, affecting its normal use and increasing maintenance costs; moreover, a tipped heater may cause serious safety accidents such as fires, especially when there are flammable materials nearby.

[0003] Existing safety measures for electric heaters have many shortcomings. While some simple protective covers can prevent direct contact with the heater surface to some extent, they may impede heat dissipation, leading to heat buildup and increasing safety hazards. Some protective devices are poorly designed, failing to effectively prevent the heater from tipping over, or failing to promptly cut off the power after tipping over, thus failing to provide the necessary protection.
