Abstract

The utility model mainly discloses a quick-connecting type filter element. At least 2 fixing holes are formed on the surface of a column body at the end head of the filter element; convex ribs are arranged on the same sides of all the fixing holes, and the side of the lower part of each convex rib that faces the fixing hole extends outwards to form an oblique angle. An accommodating chamber of the end head of the filter element is formed by internally recessing on a casing seat on which the filter element is installed, spring type fixing convex blocks corresponding to the positions and shapes of the fixing holes and slots corresponding to the positions of the convex ribs are arranged on the inner wall of the accommodating chamber, and the width of each slot is the same as the maximum width of the convex rib. The edge and the lower edge of the fixing convex block facing the slots form a slope, and a round corner is formed by the edge and the upper edge of the fixing holes close to the convex ribs. The quick-connecting type filter element has the advantages of very easy and convenient assembly and disassembly, high stability and sealing property.

Description

The fast-connecting type filter core

Technical field

The utility model relates to the filter element device in the ultra-filtration water purifier, and is special relevant with a kind of fast-connecting type filter core.

Background technology

Core component in the ultra-filtration water purifier is a filter core, and general filter core is installed on the housing seat of integral type, has water inlet and delivery port on the housing seat, after water enters, through filter element filtering, forms pure water and discharges.In general, ultra-filtration water purifier has a plurality of filter cores, makes the pure water quality that obtains higher.

The filter core of ultra-filtration water purifier generally all is to adopt helicitic texture to be rotated with on the housing seat, though this conventional fixed structure is simple, rotates not in placely in practical operation easily, causes poorly sealedly, the seepage phenomenon occurs.And helicitic texture can cause wearing and tearing, the fixing stability of time one long meeting influence.If make screw fixation method quality height, must improve screw processing quality, or adopt than good material.Will certainly raise the cost like this

Given this, the inventor designs a kind of fast-connecting type filter core, overcomes above-mentioned defective, and this case produces thus.

The utility model content

The utility model main purpose is to be to provide a kind of fast-connecting type filter core, and sealing is strong, installing/dismounting is simple.

To achieve these goals, the technical solution adopted in the utility model is:

The fast-connecting type filter core has at least 2 fixing holes on the damaged surface of filter core termination, have fin in all fixing hole the same sides, the bottom of fin, stretches towards an epitaxial lateral overgrowth of fixing hole, forms an oblique angle; Indent forms the cavity volume of filter core termination on the housing seat that filter core is installed, and has fixedly projection of the elastic press type corresponding with fixing hole position shape at the cavity volume inwall, also has the slot corresponding with the fin position simultaneously, and the width of slot is identical with the Breadth Maximum of fin; Fixedly projection is a slope towards the edge and the lower edge of slot, forms smooth fillet at fixing hole near the edge and the top edge of fin.

Described fixing hole has 4, and equidistantly arranges.

Described fixing hole is shaped as ellipse.

After adopting such scheme, the utility model forms good fixed effect by the fixedly cooperation between projection and the fixing hole, passes through the auxiliary of slot simultaneously, can easily filter core be broken away from the housing seat, and dismounting freely.

Description of drawings

Fig. 1 is the filter cartridge construction schematic diagram of the utility model preferred embodiment;

Fig. 2 is the filter core housing seat schematic diagram of the utility model preferred embodiment.

The specific embodiment

As depicted in figs. 1 and 2, preferred embodiment of the present utility model has 4 oval fixing holes 2 that equidistantly distribute on the damaged surface of its filter core termination 1.Counter clockwise direction at all fixing holes 2 has fin 3, the bottom of fin 3, stretches towards an epitaxial lateral overgrowth of fixing hole 2, forms an oblique angle 4.

Indent forms cavity volume on housing seat 5, and the filter core termination is used to plant.Have fixedly projection 6 of 4 elastic press types at the cavity volume inwall, fixedly projection 6 be will with fixing hole 2 supporting settings, its position, shape are all corresponding with fixing hole 2.On the cavity volume inwall, also have simultaneously 4 slots 7.Slot 7 is to match with fin 3, and its width depends on the Breadth Maximum of fin 3.

In addition, in order to realize removing and installing, fixedly projection 6 has gradient towards the edge and two places, lower edge of slot 7, forms the slope.And form smooth fillet at the edge and the top edge of fixing hole 2 close fins 3.This is corresponding with the slope of fixing projection 6, makes that fixedly projection 6 puts fixing hole 2 under external force under.

The utility model when mounted, the position of fin 3 corresponding slots 7 is inserted, by the fixing structure of projection 6 elastic press types, and the fixedly cooperation of projection 6 slopes and fixing hole 2 smooth fillets, filter core just is fixed on the housing seat, a side that does not have oblique angle 4 of fin 3 tightly props up the cell wall of slot 7, and stability is strong.When in dismounting, clockwise turn filter core, then oblique angle 4 relies on slots 7 cell walls, and filter core is released the housing seat.The utility model is installed fast, fixing-stable, and sealing is strong.

Above-mentioned is preferred embodiment of the present utility model just, and its part is done improvement and still belonged to protection category of the present utility model, as fixing hole 2 shape quantity and position are done suitable variation, still falls into inventive concept of the present utility model.

Claims
