This utility model relates to the field of thick film heater technology and discloses a sealing structure for a thick film heater. In use, the external water supply pipe is first inserted into the inlet end and tightened via the connecting thread. The water supply pipe then compresses the sealing gasket, causing a telescopic spring to contract the gasket, thus separating the gasket from the sealing block. This allows water to flow into the thick film heater from the inlet end. The telescopic spring also pushes the sealing gasket against the end of the water supply pipe, improving the sealing effect and preventing water from flowing out through the gap between the water supply pipe and the inlet end. When the external water supply pipe ages and breaks and needs replacement, it can be removed. When the water supply pipe is removed, the telescopic spring causes the sealing gasket to reset, causing it to abut against the sealing block and seal the inlet end, preventing hot water from flowing out during replacement and causing injury. This improves the practicality of the sealing structure of the thick film heater.
