AI Technical Summary

Technical Problem

[0003]现有的温控器在实际工作过程中，温控器内部会随外部温度变化、负载发热或动作元件升温而产生温度波动，密封腔体内的气体受热膨胀或冷却收缩后容易形成气压变化

Benefits of technology

[0016]本发明的有益效果为：本发明通过将功能模块设置于壳体内，并在盖体与壳体外周密封包覆橡胶套，使功能模块能够被盖体、壳体及橡胶套共同防护，减少外界水汽、粉尘、油污或腐蚀性介质进入温控器内部的风险，从而提高温控器的密封可靠性和环境适应性；通过橡胶套底部封堵壳体的第二开口，使壳体端部不再依赖传统刚性端盖、密封圈或点胶结构进行封闭，减少了机械拼接缝和潜在泄漏路径；橡胶套底部具有弹性形变能力，当温控器内部因温度变化、负载发热或热胀冷缩产生压力波动时，橡胶套底部能够通过弹性形变缓冲压力变化，降低壳体接缝被顶开、密封部位开裂或壳体变形的风险，从而提高全密封温控器在冷热循环、高低温冲击及复杂使用环境下的结构稳定性、动作可靠性和长期使用安全性。
