图4至图11是装有带减压功能的水流传感器电热水器示意图；
图12是密封式加热装置；
图13是半敞开式加热装置；
具体实施方式
下面结合附图1至12的实施例进行说明，附图中：外壳1、冷水进水管2、热水出水管3、带减压功能的水流传感器4、控制器5、电热管6(上电热管6-1、下电热管6-2)、出水管固定支点7、水箱8、水咀9、测温或限温开关安装管10、法兰11、泄压阀14、排污口15、水流过时加热水装置16(密闭式16-1；半敞开式16-2)、金属或非金属套管17、空气18、水19；
图1至图3是带有减压功能的水流传感器结构图，结构类似，功能相近，只是连接方式不同。
图4至图11是装有带减压功能的水流传感器4的光波加热快热式电热水器结构示意图；水箱进水通过带减压功能的水流传感器4，无论管路系统压力大小，都能快速使水箱注满水，并使其限定在设定范围内。
同时，在水箱中安装有快速加热装置16，所述快速加热是指夏天，在20秒之内能稳定供应热水；春秋只需将水箱内的水提高约10℃；冬天才需预热至约50℃；有二种结构：
①密闭式水流过时即加热水装置16-1，是在一个小容器内，设置电热管，并有进水口和出水口，打开水咀9，电热管6通电工作，水流过电热管即被加热， 通过出水口放出热水，关闭水咀，停止加热；
②半敞开式水流过时即加热水装置16-2，是在电热管上设置一个半圆形隔板16-2/1，打开水咀9，电热管6通电工作的，水流过电热管时即被加热，通过安装在半圆形隔板上的水管16-2/2，将热水直接送至水箱上部，从热水出水口放出，关闭水咀，停止加热；
附图中，水箱可用非金属吹塑或注塑制作(图9至图11是注塑水箱)，若是非金属水箱，压力限定在0.1Mpa左右，由于非金属水箱在热态具有膨胀性，能吸收热胀压力，并对活塞产生背压，而放水时则会让管路系统的压力通过，其出水量与现有热水器相同；水箱也可采用金属为基材内衬搪瓷或用不锈钢制造，若是金属水箱(含搪瓷和不锈钢水箱)，压力限定在0.2Mpa内，这就彻底克服了水箱因热胀冷缩使水箱搪瓷裂开，焊缝裂纹的问题。
附图中，电热水器有立式结构，也有卧式结构，可通用，无论是单水箱或多水箱都通用。
附图中，水箱的进水管和出水管都是采用长度＞500mm的非金属软管，形成物理水电阻，确保安全。
所述光波加热电热管6，采用非金属卤素电热管或碳纤维电热管。
若将带有减压功能的水流传感器4的A和B，分拆为二个组件也在本专利的保护之内；箭头为水流方向。
