When being embodied of the invention, before energization, reference picture 3, the iron core 3 acts on lower edge in the elastic force of lower stage clip 42 Lower chamber 21 and slide up to a high position, the iron core over-hang part 31 on the top of iron core 3 is in upper cavity 11 outside upward sliding and iron core The top of extending portion 31 is higher than the position of light emitting source 71, and at this time the light of light emitting source 71 is sheltered from by iron core over-hang part 31, photosensitive Component will not receive the light signal of light emitting source 71.
After pump is initially powered up, the iron core 3 overcomes the elastic force of lower stage clip 42 and downward under the magneticaction of magnetic circle circle Slide, at this time, the volume for the part of lower chamber 21 that lower stage clip 42 is located at reduces, pressure increase, simultaneously as iron core over-hang part 31 slide downwards, the partial volume for the upper cavity 11 that valve core spring 52 is located at become big, and pressure diminishes, at this time, lower stage clip 42 The water of the residing part of lower chamber 21 holds the top of valve element 51 after overcoming the elastic force of valve core spring 52, and further hollow from valve element Flowed into passage 32 in upper cavity 11.This process, the position of the iron core over-hang part 31 is less than the position of light emitting source 71, described Photosensitive components can receive the light of light emitting source 71.
Further, when the moment of the diode 92 cut-out half waveform, the pump instant cut-off, the magnetic circle circle is to iron The magnetic force of core 3 disappears, and at this time, the iron core 3, along the upward sliding of lower chamber 21, pushes under the elastic force effect of lower stage clip 42 The volume for the part of lower chamber 21 that spring 42 is in becomes big, and pressure diminishes, and water can be pressed into cavity of resorption by outside pressure from water inlet pipe 22 In body 21;Meanwhile valve element 51 is pressed on iron core hollow channel 32 by the valve element 51 under the elastic force effect of valve core spring 52 At upper outlet, the volume of the upper cavity 11 residing for valve core spring 52 diminishes, pressure increase, the water meeting in further upper cavity 11 The elastic force of one-way valve spring 54 is overcome to wash check valve 53 open, the water in upper cavity 11 enters the water outlet tube chamber 13 of outlet pipe 12 In and export further out.During this, the iron core over-hang part 31 can cover the light of light emitting source 71, photosensitive components The light of light emitting source 71 can not be received.
So far, the pump completes a cycling, constantly circulates said process, the pump can circulation work.
In the work period of an above-mentioned pump, the iron core often moves once, and the photosensitive components receive a hair The signal of light source 71.Once there is a discharge coefficient that can be demarcated because iron core 3 often moves, if discharge coefficient is K, i.e. K= V/cycle,
Due to:
V=L*S=(L2-L1) * 1/*4 π * D2
K=(L2-L1) * 1/4* π * D2/cycle;
So total flow is:
FLOWRATE=K*TOTAL CYCLE/min.
Wherein, the S is the area of section of upper cavity 11, and D is the diameter of upper cavity 11, and the L2 is the highest of iron core 3 Point and the difference in height of minimum point, the L1 are the peak of iron core 3 and the difference in height of its position under off-position.
Above is the preferable implementation to the present invention is illustrated, but the invention is not limited to the implementation Example, those skilled in the art can also make a variety of equivalent variations on the premise of without prejudice to spirit of the invention or replace Change, these equivalent deformations or replacement are all contained in the application claim limited range.
