Put, and positioned at the both sides of geared worm 431, engaged by respective transmission worm gear 511 and same geared worm 431.Two biographies
Dynamic worm gear 511 is rotated along different directions, if an edge rotates clockwise, another is just rotated counterclockwise.It is corresponding, meter
The rotation direction of the aobvious number wheel 550 of number mechanism 500 is also different.
When the accumulative water flow of one of counting mechanism 500 reaches the operating limit of corresponding filter core, the filter core more renewed
Afterwards, the reset button 610 of corresponding counting mechanism 500 is pressed, corresponding counting mechanism 500 is resetted, new from new start recording
The accumulative water flow of filter core.And another counting mechanism 500 side by side is unaffected, can still continue to record its corresponding filter
Core, and correspond to when filter core reaches service life and replaced at it, it is same after replacement only to reset corresponding counting mechanism 500 i.e.
Can.Filter element life monitor 200 is realized while independently monitors the function of two kinds of filter cores.
The filter element life monitor 200 of the present invention can set multiple counting mechanisms 500, independent to monitor making for multiple filter cores
With the service life, and can be after single filter element replacing, individual reset.Realize the independent monitoring of multiple filter cores.Avoiding can only be at the same time
The problem of replacing all filter cores, greatly reduces the waste to filter core.
And the filter element life monitor 200 of the present invention is pure mechanic structure, it is not necessary to powers, also can normally make outdoors
With, can be used for remote districts and other unpowered situations uses.
The manual clarifier 100 of the present invention, is provided with above-mentioned filter element life monitor 200, and using pump 120 manually into
Row draws water so that manual clarifier 100 of the invention can be applied to remote districts and the open airs of other unpowereds, can be from
Limitation purifies water source, provides the drinking water of health for people at any time.It can realize at the same time and the longevity is used to multiple filter cores
The independent monitoring of life, reduces the waste to filter core.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, its description is more specific and detailed, but simultaneously
Cannot therefore it be construed as limiting the scope of the patent.It should be pointed out that come for those of ordinary skill in the art
Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
