The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.
Fig. 1 is extremely shown in Figure 5 to be structural representation of the present invention.
Reference numeral wherein is: the protruding circle in filter cylinder 1, intake chamber 1a, the 1b of filter chamber, location 11, sealed groove 12, filter cylinder lid 2, water inlet 2a, delivery port 2b, first plunger cavity 21, second plunger cavity 22, location be protruding chews 23, filter core 3, first plunger 4, first annular groove 41, second plunger 5, second annular groove 51, lever 6, rotating shaft 61, microswitch 7, first sealing ring 81, second sealing ring 82, rubber seal 83, impurity 9.
Extremely shown in Figure 5 like Fig. 1; Filter with automatic detection architecture of the present invention; Comprise filter cylinder 1 that is shaped on an open end and the filter cylinder that cooperates with its liquid sealing lid 2 and be installed in the filter core 3 in the filter cylinder; Said filter core 3, filter cylinder lid 2 and filter cylinder 1 match and are formed with intake chamber 1a and the 1b of filter chamber; Filter cylinder lid 2 is shaped on water inlet 2a that is communicated with intake chamber 1a and the delivery port 2b that is communicated with the 1b of filter chamber, and wherein: filter cylinder covers 2 tops and also is shaped on first plunger cavity 21 that communicates with intake chamber 1a and second plunger cavity 22 that communicates with the 1b of filter chamber, and first plunger cavity, 21 liquid sealings are fitted with first plunger 4 of the upper and lower motion of ability; Correspondingly, second plunger cavity 22 is fitted with second plunger 5; Said first plunger 4 all contacts cooperation with the lever 6 that with rotating shaft 61 is fulcrum mutually with second plunger 5, and can promote lever 6 and trigger microswitches 7 and convert pressure signal into the warning signal of telecommunication.The present invention utilizes the variation of intake chamber 1a and the 1b of filter chamber hydraulic pressure pressure, acts on the lever 6 through first plunger 4 and second plunger 5, and converts pressure signal into the warning signal of telecommunication through lever 6 triggering microswitches 7; Thereby can realize detecting automatically, detect the filter capacity size of filter core, the duty of real-time judge filter core; Guarantee the filter core operate as normal; As shown in Figure 2, when filter core stops up, because the hydraulic pressure of intake chamber 1a increases and the hydraulic pressure of the 1b of filter chamber reduces; Thereby make the thrust of first plunger 4 cause lever 6 to tilt to second plunger, 5 directions greater than second plunger 5; Lever 6 disengagings contact with microswitch 7, realize reporting to the police, and make people can accurately and timely judge the service life of filter core through pressure differential.
Among the embodiment, first plunger 4 and second plunger 5 lay respectively at the both sides of rotating shaft 61 and match with lever 6.The position of lever 6 fulcrums can be poor according to the service pressure of different filter cores, regulates.The cross section of first plunger 4 and second plunger 5 also can be poor according to the service pressure of different filter cores, regulates.In real work; Since material that every kind of filter core adopted different with filtering function require different; Therefore its service pressure value is also different, and lever 6 and first plunger 4, second plunger 5 can be regulated, and can make the present invention make corresponding adjustment according to actual conditions; Make it can be suitable for various filter cores, guarantee the accuracy that detects.
Among the embodiment, like Fig. 4, shown in Figure 5, first plunger 4 is shaped on first annular groove 41, and first annular groove 41 is fitted with first sealing ring 81; Said second plunger 5 is shaped on second annular groove 51; And second annular groove 51 is fitted with second sealing ring 82, and said first plunger 4 and second plunger 5 cooperate with first plunger cavity 21 and second plunger cavity, 22 liquid sealings through first sealing ring 81 and second sealing ring 82 respectively.First annular groove 41 and second annular groove 51 all are shaped on the twice groove.Plunger adopts soft wear-resisting sealing ring sealing through being shaped on groove, can reduce manufacturing cost, reduces the accuracy of manufacture of plunger and plunger cavity, makes product can reach the requirement of design technology, can reduce cost again.Be shaped on the twice groove, adopt double density seal sealing can improve the sealing property of plunger, also have balanced action simultaneously, prevent that plunger from tilting.
Extremely shown in Figure 3 like Fig. 1; Filter cylinder of the present invention 1 bottom centre is shaped on the location protruding circle 11 suitable with filter core 3 internal diameters; The center of correspondingly said filter cylinder lid 2 is shaped on to what extend below and chews 23 with the suitable location of filter core 3 internal diameters is protruding; Said filter core 3, the protruding circle 11 in location and locate protruding 23 inner spaces that surround of chewing and constitute the 1b of filter chamber, and constitute intake chamber 1a with space outerpace that the inwall of filter cylinder lid 2, filter cylinder 1 surrounds.Filter core 3 and protruding circle in location 11 and location be protruding chews 23 and matches, and the inner chamber of filter cylinder 1 is separated into intake chamber 1a and the 1b of filter chamber, and former water is from water inlet 2a entering intake chamber 1a, and is full of intake chamber 1a; Because the pressure effect, former water filters to the 1b of filter chamber through the filter screen of filter core and infiltrates, and after the water purification that filters is full of the 1b of filter chamber, upwards protrudingly through the location along filter core 3 inner chambers chews 23, delivery port 2b outflow is for people to use.
Among the embodiment, filter cylinder lid 2 adopts the screw fit assembling with filter cylinder 1, and filter cylinder 1 be shaped in ring sealed groove 12, said sealed groove 12 is fitted with soft wear-resisting rubber seal 83.Filter cylinder lid 2 passes through rubber seal 83 with filter cylinder 1, realizes that liquid sealing cooperates, and like Fig. 4, shown in Figure 5, the diameter of second plunger cavity 22 is greater than the diameter of first plunger cavity 21.According to the size of the pressure principle of water design plunger can balance filtration chamber 1b with intake chamber 1a because hydraulic pressure is different, and the pressure differential of formation.
The present invention realizes detecting filter core to stop up like this:
As shown in Figure 1, normally not during blocked state, former water gets into intake chamber 1a through water inlet 2a, is full of intake chamber 1a, and hydraulic pressure simultaneously and first plunger 4 interact; First sealing ring 81 makes former water not leak with rubber seal 83.Former water is full of the 1b of filter chamber through filter core 3 and flows to second plunger 5 and delivery port 2b; Second sealing ring 82 only flows out the water after the filtration from the delivery port 2b of filter cylinder lid 2, though the pressure of first plunger 4 is bigger than the pressure of second plunger 5, the area of second plunger, 5 to the first plungers 4 is big; Thereby the thrust of second plunger, 5 suffered current is also big; Influenced by this, second plunger 5 promotes lever 6 and triggers microswitch 7, is in normal operating conditions.
As shown in Figure 2, during blocked state, after former water got into filter, former water was full of intake chamber 1a, and hydraulic pressure acts on first plunger 4 simultaneously, and first sealing ring 81 makes former water not leak with rubber seal 83.Filter core 3 has lost filtration owing to stopped up by impurity 9 after the use of normal phase, and former water can not filter and pass through; Or water-flowing amount departs from normal value, causes the pressure of former water intake chamber 1a to rise, and therefore second plunger, 5 thrusts reduce; First plunger 4 moves up the contact separation of lever 6 with microswitch 7; Make it to break off, system receives signal, begins to report to the police.
Most preferred embodiment of the present invention is illustrated, and various variations or the remodeling made by those of ordinary skills can not depart from the scope of the present invention.
