This application provides a thermal protection component and a thermal component, relating to the field of semiconductor or photovoltaic material processing, and solves the technical problem that product fragments falling onto the heating structure after a furnace tube ruptures, easily damaging the heating structure. The thermal protection component includes a protective element disposed between the heating structure and the furnace tube, and located below the furnace tube. After the furnace tube ruptures, the protective element can support the product, preventing short circuits caused by product contact with the heating structure and thus preventing thermal damage. Furthermore, when the protective element is removed from the furnace chamber, it can also pull the product out of the furnace chamber, improving cleaning efficiency. In addition, since the protective element is only located below the furnace tube, the obstruction area on the heating structure is small, reducing the impact on heating efficiency.

This utility model discloses an exhaust piston for a dispensing syringe, comprising a syringe, a first filter plate fixedly connected inside the syringe, a telescopic rod fixedly connected to the top of the first filter plate, a limiting groove formed inside the telescopic rod, a locking block slidably connected inside the limiting groove, and multiple blades fixedly connected to the outside of the telescopic rod. Through this structure, the impact force drives the internal telescopic rod to move, causing the internal locking block to move within the limiting groove, thus causing the telescopic rod to rotate the external blades, pulverizing impurities on the surface of the first filter plate. This breaks large impurities into tiny particles, which can either be discharged with the glue through the filter holes or reduce the clogging area of ​​the filter holes, extending the effective service life of the filter plate and avoiding problems such as sudden reduction in glue output or glue breakage due to clogging.
