实施例1
如图1所示，一种防水性手动复位温控器，包括温控器本体21、复位推杆13、橡胶套16和绝缘套20，温控器本体21包括壳体，壳体由上壳体18和下壳体10装配在一起构成；壳体内设置有垫圈9、双金属元件8、顶柱5、接触片3、第一触点4、第二触点6、弹簧片7；上壳体18中插入有第一铆钉2和第二铆钉22，上壳体18上设置有第一端子11和第二端子12，第一端子11通过第一铆钉2固定在上壳体18上，第二端子12通过第二铆钉22固定在上壳体18上；双金属元件8和垫圈9设置在下壳体10内；双金属元件8设置在下壳体10的底部，垫圈9位于双金属元件8上方；顶柱5插入垫圈9中；接触片3的一端连接到第一铆钉2的下端，接触片3的另一端设置有第一触点4；复位推杆13插入上壳体18中，弹簧片7设置在复位推杆13的下端，第二触点6设置在弹簧片7上；橡胶套16盖在复位推杆13的上端，橡胶套16的下端与上 壳体18紧密贴合在一起；上壳体18上覆盖有环氧树酯层19；绝缘套20套在环氧树酯层19上，环氧树酯层19的下端与绝缘套20的下端通过环氧树脂胶粘接在一起；橡胶套16的下端嵌入环氧树酯层19中。橡胶套16能够防水，避免水进入温控器本体21的内部。
本实用新型连接在加热电路中，在加热过程中，复位推杆13处于按下的状态，第二触点6和第一触点4相接触，加热电路接通，双金属元件8为向下弯曲的状态，当温度达到所设定的值时，双金属元件8反向向上弯曲，并触碰到顶柱5的下端，使顶柱5向上推动弹簧片7，弹簧片7再带动第二触点6运动，使第一触点4和第二触点6分离，加热电路断开，加热停止；当需要再次加热时，用手按下橡胶套16，复位推杆13向下运动，使第二触点6和第一触点4相接触，接通加热电路开始加热，且推动顶柱5向下运动，顶柱5的下端向下推动双金属元件8向下运动，使双金属元件8向下弯曲复位。
实施例2
如图2所示，实施例2与实施例1不同之处在于橡胶套16的下端还套箍有一个卡环17，卡环17的下端嵌入环氧树酯层19中，卡环17使橡胶套16更牢固地固定在上壳体18上。实施例2的其他结构与实施例1相同。
实施例3
如图3所示，一种防水性手动复位温控器，包括温控器本体21、复位推杆13、橡胶垫圈14、按钮15、橡胶套16、卡环17和绝缘套20，温控器本体21包括壳体，壳体由上壳体18和下壳体10装配在一起构成；壳体内设置有垫圈9、双金属元件8、顶柱5、接触片3、第一触点4、第二触点6、弹簧片7；上壳体18中插入有第一铆钉2和第二铆钉22，上壳体18上设置有第一端子11和第二端子12，第一端子11通过第一铆钉2固定在上壳体18上，第二端子12通过第二铆钉22固定在上壳体18上；双金属元件8和垫圈9设置在下壳体10内；双金属元件8设置在下壳体10的底部，垫圈9位于双金属元件8上方；顶柱5插入垫圈9中；接触片3的一端连接到第一铆钉2的下端，接触片3的另一端设置有触点4；复位推杆13插入上壳体18中，弹簧片7设置在复位推杆13的下端，第二触点6设置在弹簧片7上；复位推杆13的上端插入按钮15中；橡胶套16盖在按钮15的上端，橡胶套16的下端与上壳体18紧密贴合在一起；按钮15的下端与上壳体18之间设置有橡胶垫圈14，橡胶垫圈14套在复位推 杆13上；上壳体18上覆盖有环氧树酯层19；绝缘套20套在环氧树酯层19上，环氧树酯层19的下端与绝缘套20的下端通过环氧树脂胶粘接在一起；卡环17套箍在橡胶套16的下端。
在加热过程中，双金属元件8为向下弯曲的状态，第二触点6和第一触点4相接触，加热电路处于接通状态，当加热到温度达到所设定的值时，双金属元件8反向向上弯曲，并触碰到顶柱5的下端，推动顶柱5向上运动，顶柱5推动弹簧片7，弹簧片7向上弹起，带动第二触点6向上运动，第二触点6与第一触点4分离，加热电路断开，加热停止；当需要再次加热时，用手按下橡胶套16，按钮15和复位推杆13向下运动，使第二触点6和第一触点4相接触，接通加热电路开始加热，同时推动顶柱5向下运动，顶柱5的下端向下推动双金属元件8向下运动，使双金属元件8向下弯曲复位，此时，橡胶垫圈14受到按钮15挤压产生形变。当放开按钮15时，复位推杆13、橡胶垫圈14和橡胶套16恢复到初始状态。
本实用新型提供的防水性手动复位温控器，结构简单，设计科学，能够防止水进入温控器本体内部，操作方便，能够实现手动复位，灵敏度高，可以很好地满足实际应用的需要。
以上所述实施例仅表达了本实用新型的实施方式，其描述较为具体和详细，但并不能因此而理解为对本实用新型专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。因此，本实用新型专利的保护范围应以所附权利要求为准。
