Abstract

A falling-water filter comprises a shell, a filter basket and a filter plug. The filter basket is provided with a central hole at the bottom, and a hollow column is fixed on the filter basket. The filter plug consists of a handle, a supporting cover body with filtration pore, a sealing component, and a column-shaped inserting rod. The column-shaped inserting rod passes through the central hole in the filter basket to connect the sealing component on the waterspout on the bottom of the shell with the supporting cover body. In the utility model, the handle arranged on the upper part of the filter basket, the supporting cover body and the sealing component on the lower part are connected integrally; when the handle is pressed down, the inserting rod goes downward to close together the sealing component and the waterspout of the shell, thereby achieving water storing; when the handle is lifted up, the sealing component goes up together with the inserting rod to separate from the waterspout of the shell, thereby achieving water draining. When in draining water, relatively big remains are blocked on the supporting cover body, while tiny remains are kept in the filter basket. With a simple structure, excellent air-tightness and anti-blocked effect, the utility model can be used conveniently. The utility model provides a novel product for falling-water filters in drainages.

Description

Plumbing filter

Technical field

The utility model relates to a kind of dewatering installation, specifically is used for sink or water storage tub, draining and can prevent a kind of device that drain gully stops up.

Background technology

Along with improving constantly of people's living standard, the conventional washing groove that family and hotel are used (comprising tank, bathtub) is replaced by form, different stainless steel trough or the high-grade ceramic bathtub of specification, therefore the plumbing filter that matches with it also requires superior, not only require its energy when retaining watertight, and can all tiny foreign material of effectively catching when draining.Traditional push button plumbing filter all ubiquity can not prevent effectively that tiny foreign material from flowing into the possibility of sewer with current.The patent No. is " 97224555 ", " plumbing filter ", though it has the function of draining, retaining, filtration, tiny foreign material can enter sewer from the filter opening around the filter lid when draining, so service time is long slightly, can cause sewer to stop up unavoidably.The patent No. is " 01233703.x ", " push button plumbing filter ", it can be with all foreign material in the sink through a lid and a filter basket second interception, can stop the possibility that sewer stops up, but the sealing ring on the lid of this plumbing filter and the housing bottom drain gully lay respectively at filter basket on, down, so be disconnected from each other, a lid that has handle only plays the function of holding back thick foreign material, the larynx of plugging into that sealing ring can only lean on the table top control assembly to be connected is controlled the retaining and the draining of sink, therefore it has not only increased its cost, and can not be applied to not have the sink of control assembly.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art and defective, designs a kind of plumbing filter that can match with various multi-form sinks and use.This plumbing filter comprises housing, filter basket and filtration chock plug, housing bottom has outfall, the filter basket bottom has centre bore, filter chock plug by handle, a lid of band filter opening, seal and inserted link are formed, cylindrical inserted link pass the filter basket centre bore will be positioned on the housing outfall seal with prop up a lid and be connected; Inserted link is connected to each other by upper plunger and lower plunger and forms, and centre bore and handle that a lid is passed on its top spin, and sealing member sheathing is takeed at the screw thread of lower plunger, is fixed in the middle of the inserted link after spinning with upper plunger; Spring and steel ball are equipped with in the bottom of inserted link, and this steel ball compresses mutually with housing bottom copper insert center bore inner wall; Fix a hollow cylinder on the filter basket centre bore, its aperture size is less than a lid central circular entity.The utility model will be positioned at the seal of filter basket below and top and prop up lid and link into an integrated entity, as long as handle is mentioned, seal upwards and with the housing outfall breaks away from and draining with inserted link, because of elastic force effect steel ball compresses mutually with the copper insert inwall, so inserted link can be fixed at copper insert centre bore axial location any part, can control drainage speed like this.Press handle, inserted link makes seal and the driving fit of housing outfall downwards and retaining, and sealing performance is fine.During draining, thicker residue is trapped on the lid, and tiny foreign material are trapped in the filter basket, can prevent that residue from flowing into sewer and result in blockage.It is simple in structure, and is easy to use, has increased a kind of new varieties of function admirable again for the plumbing filter in the dewatering installation.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

Label among the figure is: 1-nut, 2-packing ring, 3-handle, 4-prop up lid, 5-handle, 6-upper plunger, 7-hollow cylinder, 8-filter basket, 9-base nut, 10-housing, 11-exterior seal ring, 12-inner seal ring, 13-lower plunger, 14-copper inlay, 15-steel ball, 16-spring.

The specific embodiment

Shown in accompanying drawing, the bottom of the housing 11 of this plumbing filter has outfall, and there are the copper inlay 14 of a band endoporus, uniform three or four drainage channels around the copper inlay in its center.Place a filter basket 9 in housing, handle 3 is housed on the filter basket, its bottom and perisporium have filter opening, and hollow cylinder 7 spins with the base nut 9 of filter basket below, makes it be fixed on the filter basket center.The filter basket top has one to filter chock plug, and it is made up of handle 5, a lid 4, plug-in unit and seal.The center of propping up lid 4 is circular entity, has filter opening all around.The diameter of its circular entity can not flow out sewage greater than the hollow cylinder diameter at filter basket center from hollow cylinder.The centre bore that a lid is passed on the top of upper plunger 6 spins mutually with handle 5.After putting the seal of forming by exterior seal ring 11 and inner seal ring 12 on the screw thread shoulder of lower plunger 14, spin mutually with upper plunger 6, and seal is positioned on the outfall.Spring 16 and steel ball 15 are housed in the bottom of lower plunger, and this steel ball compresses mutually with steel inserts center bore inner wall under the spring force effect.Whole filtration chock plug can be along the upper and lower pulling of the hollow cylinder of filter basket.This plumbing filter fixes by nut 1 and stainless steel sink, during installation, loads onto packing ring 2 at housing edge and sink junction.During use, press handle 5, inserted link drives inside and outside sealing ring downwards and the driving fit of housing outfall and retaining.The pull-up handle, driving a lid and whole inserted link breaks away from and draining the outfall of inside and outside sealing ring and housing, and can control drainage speed by the height of mentioning inserted link, sewage enters outfall around a lid and filter basket, thick slag thing is trapped on the lid, thinner slag thing just is collected in the filter basket, mentions handle 3, can easily the residue thing be outwelled with handle 3.This plumbing filter is installed without any need for auxiliary body in sink.
