The invention discloses a front-mounted backwash filter. The backwash filter comprises a filter main body, a sleeve, a cover, a control rod, a hand wheel, a filter screen, a joint and a hose joint, wherein the filter main body and the sleeve form a water channel structure, a tap water inlet and a filter water outlet which are communicated with a water channel are respectively formed in the two sides of the filter main body, the filter main body and the sleeve are communicated through a water channel formed by a backwash hole inlet, the upper part of the control rod is provided with a control rod tap water inlet communicated with the water channel of the tap water inlet, the middle upper part of the control rod is provided with a water sealing plug which is positioned below the control rod tap water inlet, and the lower part of the control is provided with a control rod tap water outlet positioned below the water sealing plug. According to the front-mounted backwash filter, due to the adoption of the principle of switching the backwash water in the flowing direction, backwash water such as gravels and impurities, which is blocked in the filter screen, can be rushed into a sewage discharging hole, the impurities of the filter screen can be cleaned, the operation is convenient, the structure is simple, and the blocked impurities can be cleaned.
Description
Technical field
The present invention relates to the technical field of filtration device structure, particularly relate to a kind of there is backwashing function and forward type design forward type backwash filter.
Background technology
At present, the sanitary bath equipment that existing life staying idle at home or place, hotel etc. use, a lot of tap all wherein or gondola water faucet water outlet place are provided with filter plant, these filter plants not only can purified water source, filter fine impurity etc., also the contaminant filter such as gravel, iron rust can be separated simultaneously, purify water.But filter in use for some time, these gravel, iron rust etc. can accumulate and stick on filter screen, cause blocking and the breed bacteria of filter screen, also can lower the water velocity of filter effect and water outlet of slowing down to a certain extent simultaneously.And in prior art, the impurity of this type of filter is cleared up, be all generally that the filter screen by dismantling filter is cleaned out, troublesome poeration, loaded down with trivial details, also inconvenient; But not some filter product specially for cleaning filter screen impurity and without the need to dismantling filter do not occur in prior art.
Summary of the invention
The object of the invention is the shortcoming in order to overcome above-mentioned prior art, a kind of forward type backwash filter is provided, this forward type backwash filter can ensure just conventional water, without the need to dismantling filter during the impurity such as gravel, iron rust in cleaning filter screen, adopts the principle switching water (flow) direction back-flushing, back-flushings such as the gravel be blocked in filter screen, impurity, pour sewage draining exit, realize cleaning filter screen impurity, easy to operate, structure is simple, and cleaning blocking impurity is clean.
The technical solution adopted for the present invention to solve the technical problems is: a kind of forward type backwash filter, comprise filter body, with the sleeve coordinated is installed bottom filter body, with filter body top, the lid coordinated is installed, to be placed in filter body and sleeve and to protrude the control lever of lid, to be connected with control lever and rotatable control lever realizes the handwheel of control lever pull lift action, to be placed in filter body and sleeve and to entangle the filter screen of control lever, sleeve bottom is provided with movablely with control lever installs the joint be connected, joint is connected and installed with hose coupling, described filter body and sleeve form the structure with water channel, filter body both sides are respectively equipped with the running water water inlet and filtered water delivery port that communicate with water channel, form water channel by recoil inlet opening between filter body with sleeve to communicate, control lever top is provided with the control lever running water inlet opening communicated with the water channel of running water water inlet, control lever middle and upper part is provided with the water sealing plug being positioned at and also can clogging recoil inlet opening below control lever running water inlet opening, control lever bottom is provided with the control lever running water outlet hole be positioned at below water sealing plug, filtered water delivery port communicates with the water channel of sleeve.
The operation principle of this forward type backwash filter is: during normal use water outlet, water enters from running water water inlet, now water sealing plug can close recoil inlet opening, make water can not enter from recoil inlet opening, then control lever running water inlet opening is entered, flow out and net filtration after filtration from control lever running water outlet hole, through the water outlet of filtered water delivery port after filtration, and the port that now bottom of control lever also clogs joint makes water can not flow out from joint; When needs carry out backwash, to outward winding counterclockwise handwheel, drive the lift of control lever, water sealing plug no longer closes recoil inlet opening, control lever running water inlet opening is also sealed and is not communicated with the water channel of filter body, the bottom of control lever and joint are formed and depart from, water enters from running water water inlet, sleeve is entered through recoil inlet opening, rinse from the outer wall of screen pack to the inwall of filter screen, impurity such as being jammed in the gravel of its interior and iron rust is washed open, and gravel and iron rust etc. to fall in joint and wash away, and complete backwash.After flushing, use when need normally make, only need be tight handwheel dextrorotation, makes control lever etc. reset and can normally use.
Further, described running water water inlet and filtered water delivery port are provided with nut block, be provided with an O type circle water-tight, be provided with the 2nd O RunddichtringO water-tight between filter body and sleeve between lid and filter body.
In sum, forward type backwash filter of the present invention can ensure just conventional water, cleaning filter screen in the impurity such as gravel, iron rust time without the need to dismantling filter, adopt the principle switching water (flow) direction back-flushing, back-flushings such as the gravel be blocked in filter screen, impurity, pour sewage draining exit, realize cleaning filter screen impurity, easy to operate, structure is simple, and cleaning blocking impurity is clean.
