Molding block is connect with pressure sensor, filter element life cue module and inlet valve control module respectively.Such as Fig. 4, it illustrates
The working principle diagram of the net water dispenser leakage inspector of the embodiment of the present invention.
Specifically, the embodiment of the invention provides can with intelligent decision complete machine whether the detection scheme of leak.Wherein, working as
The pressure sensor of a MEMS is inserted into preceding inlet valve rear end water inlet pipe, which can be either vertically or horizontally in water
In road (different modes of emplacement internal judgment conditions are different), while the pressure value of detection sensor and the frequency spectrum due to water impact
Value.Normal water circulation is out-of-date, spectrum value (the vortex oscillation frequency that water flow generates) and pressure change time synchronization, and if there is micro-
When small leakage, pressure value variation, spectrum value is constant, and when there is water pipe explosion, pressure value returns to open type initial value, spectrum value
More than maximum value.Changed by the two data difference, it can be determined that whether have leakage point in water route.Meanwhile the sensor it is long when
Between under operating status, can by the changing inversely (pressure value becomes larger, and spectrum value becomes smaller) of the absolute value and spectrum value of pressure,
Such as a reference value judged for filter element replacing can be 0.2 times of a reference value for leak judgement, so that whether estimate needs
Replace filter core.
