Description

Technical Field

[0001] The present invention relates to the technical field related to outdoor heater protection, and in particular to an outdoor heater with a protection function. Background Art

[0002] Outdoor heaters are devices used to keep people warm when they are outdoors. They are often used in hotel lobbies, restaurants, outdoor gardens, sentry booths, various exhibitions and other leisure places. Due to the increasingly prominent disadvantages of gas heaters, such as carbon dioxide emissions, fire hazards, and ultraviolet carcinogenicity, gas heaters are gradually being replaced by electric heaters. When using an outdoor electric heater, you need to adjust the height of the heater according to different usage scenarios. For example, in places where there are many children, you need to raise the height of the heater to prevent children from touching the heating wire and getting burned. However, when the outdoor heater is raised to a higher position, the center of gravity of the entire heating device is relatively biased upward, and when it is hit, it is very easy to fall over, causing injuries.
