Heater structure

The invention relates to a heater structure includes a heating core, at least one heating tube and a temperature switch. The heating core has an inlet, an outlet and an inner space, in which the inlet, the outlet and the inner space can be integrated to form a channel. The heating core has a first lateral wall with a first thickness, and the first lateral wall has an installation portion with a second thickness, in which the first thickness is different to the second thickness. The heating tube providing the thermal energy contacts the heating core. The temperature switch is used for sensing temperature, contacting the installation portion, and reducing the temperature at the temperature switch so as to prevent the heating core from frequently being started/shut down and from being over high in temperature. 本发明涉及种加热芯结构，其包括加热芯、至少加热管及温度开关，加热芯具有入口端、出口端以及内部空间，入口端、出口端及内部空间形成通路，加热芯具有第侧壁，第侧壁具有第厚度，在第侧壁设有安装部位，安装部位具有第二厚度，第厚度与第二厚度不同，加热管用于提供热能，加热管与加热芯接触，温度开关用于感测温度，温度开关与安装部位接触，降低积存于温度开关处的温度，因此可避免加热芯频繁地启动/关停，也可避免加热芯的温度过高。
