Background
In recent years, with the increasing of living standard, the use of tap water is more and more popular, and in the delivery pipelines of the domestic water, water leakage happens sometimes, if the leakage cannot be found in time, not only inconvenience is brought to life, but also resources are wasted, property loss is brought, and even safety accidents are seriously caused, for example, the indoor water leakage easily soaks furniture and floors, and the circuit safety problem is also caused. Some protection products for detecting water leakage appear in the market, and are generally divided into electronic products and mechanical products, wherein the electronic products are characterized in that a leakage point is detected, but the range of water leakage detection is smaller; when mechanical products are detected, the detection cannot be carried out under the condition of small water leakage.
In addition, the general detection method of the existing protection products for detecting water leakage is to determine whether water leakage occurs by detecting whether the flow rate of water flow exceeds a set limited flow rate, that is, the existing detection method generally considers that a maximum flow rate exists during normal water consumption, and when leakage occurs, the flow rate of water flow is greater than the flow rate of normal water consumption, so that the water leakage is determined when the flow rate exceeds the flow rate of normal water consumption, and the flow rate of normal water consumption is the limited flow rate determined according to the habit of normal water consumption. However, the method has the disadvantages that when the water flow is less than the set limited flow rate, whether water leakage occurs cannot be judged, so that water leakage with small flow cannot be detected, for example, if the normal water flow rate of the water tap is forgotten to be closed, water leakage cannot be judged in time and measures are taken to remind a user to close a water source in time; moreover, if the set limiting flow rate is too low, the daily water usage is affected; in addition, the flow rate of the normal water is not fixed, a plurality of water taps are needed to be used at the same time sometimes, and only one water tap is needed sometimes, so that the limited flow rate which needs to be set is difficult to determine and varies from person to person, so that the water leakage condition judged by the method has large errors, poor accuracy and low sensitivity. In addition, the existing protection product for detecting water leakage needs to detect whether the flow rate of water flow exceeds the limited flow rate, so that the requirement on the detection of the flow rate of water flow is high, the detection of the flow rate is difficult, the calculation is complex, and the cost of the product is high.
