The accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the cross section structure schematic diagram of a kind of filter for purifier of the present invention;
Fig. 2 is the structural representation of another kind of the present invention for the filter of purifier;
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
As shown in Figure 1, a kind of filter for purifier, be positioned at the upper shell 1 and the lower house 2 that is positioned at below of top, this upper shell 1 is tightly connected with lower house 2, upper shell 1 is provided with metal screen with lower house 2 connections, the cross sectional shape of the shape of this metal screen and lower house 2 inner chambers is suitable, lower house 2 is provided with running water water inlet 21 and running water outlet mouth 22, running water water inlet 21 is fixedly connected with running water water inlet pipe 23, running water outlet mouth 22 is fixedly connected with running water outlet pipe 24, upper shell 1 is provided with water purification delivery port 11, water purification delivery port 11 is fixedly connected with water purification outlet pipe 13, running water outlet pipe 24 is provided with out water control switch 241, water purification outlet pipe 13 is provided with water purification gauge tap 131.In the present embodiment, the sintered meshwork 3 of metal screen for being formed by multilevel-cell filter screen sintering, in order to guarantee the quality of filtered water, the filtering accuracy of sintered meshwork is 10 μ m-0.01 μ m, sintered meshwork 3 is comprised of 5 to 12 layers of unit filter screen.In the present embodiment, preferred, this sintered meshwork is comprised of 5 layers of unit filter screen, and filtering accuracy is 1 μ m, and the filtering accuracy of the unit filter screen bottom being positioned at is less than the filtering accuracy of the unit filter screen that is positioned at top.In Water treatment, close out water control switch 241, running water is entered in lower house 2 by running water water inlet pipe 21, under the effect of pressure, current are entered in upper shell 1 after sintered meshwork 3 filters by lower house 2, the unit filter screen that oarse-grained impurity is positioned at bottom filters, and then by other unit strainer filterings of top, water purification flows out from water purification outlet pipe 11 short grained impurity successively.After water purification gauge tap 131 cuts out, open out water control switch 241, water purification moment on sintered meshwork 3 tops upwards, upper shell 1 Central Plains has air compressed, water purification after being filtered is the back flush sintered meshwork under the effect of gravity and compressed air bounce, and water purification and running water flow out from outlet pipe simultaneously.In this process, do not need dismounting, do not need solenoid electric valve, just good reverse cleaning sintered meshwork.
As shown in Figure 2, be the filter of another kind of the present invention for purifier, it comprises upper shell 1, lower house 2 and is embedded at the sintered meshwork 3 that upper shell 1 is connected with lower house 2, and upper shell 1 is connected with the junction employing welded seal between lower house 2.Lower house 2 is provided with running water water inlet 21 and running water outlet mouth 22, running water water inlet 21 is fixedly connected with running water water inlet pipe 23, running water outlet mouth 22 is fixedly connected with running water outlet pipe 24, upper shell 1 is provided with water purification delivery port 11, water purification delivery port 11 is fixedly connected with water purification outlet pipe 13, and running water outlet pipe 24 is provided with out water control switch 241, water purification outlet pipe 13 is provided with water purification gauge tap 131.In order better to reach goal of the invention of the present invention, the inside of upper shell 1 and be provided with elastic diaphragm device 4 between its roof and water purification delivery port, when water purification gauge tap 131 cuts out, after running water gauge tap 241 is opened, the instant water of upper shell 1 inside upwards, it is large that pressure becomes, elastic diaphragm device 4 is extruded distortion under the effect of pressure, the water purification on sintered meshwork 3 tops back flush sintered meshwork under the effect of the bounce of gravity and elastic diaphragm, meanwhile water purification and running water flow out from the running water outlet pipe simultaneously, this process simultaneously well reverse cleaning sintered meshwork 3.In the present embodiment, arranging of elasticity elastic diaphragm device strengthened the cleaning performance of sintered meshwork and accelerated cleaning speed.
In the present invention, metal screen can also be for by metal dust or the metallic fiber sintered sintering felt formed, the filtering accuracy 10 μ m-0.01 μ m of sintering felt, the filtering accuracy of preferred sintering felt adopts 1 μ m, can improve significantly the quality of drinking water equally, reduce the replacement cost of the filter core of purifier.Sintered meshwork or sintering felt adopt 304 stainless steels, 316L stainless steel or copper product or other metal materials that meets the food contact material standard to make.
The present invention utilizes the impurity on the principle clean metal filter screen that the effect of natural gravity, siphonage and the compressed air bounce of water rinses residual in the other direction, reach the purpose of permanent use, greatly reduce production cost, the user does not need more renew cartridge can reach good production effect.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
