Abstract

The utility model provides a wire dust filter, comprising a front cover and a back cover. The utility model is characterized in that the link construction at both sides of the back cover's lower part is a hemispherical protrusion installed in the hole at the lower part of the front cover which makes the back cover connect to the front cover. The upper part of the back cover is a staircase retracting inward, and the corresponding point of the front cover is provided with a blocking rib. Adopting the link construction of the front cover and the back cover of the utility model can assure the reliable connection and can also make the dismounting of the front cover and the back cover more convenient and easier.

Description

Line bits filter

Technical field

The utility model relates to a kind of use in washing machine line bits filter, specifically existing line is considered to be worth doing the improvement of filtration device structure.

Background technology

The line of washing machine bits filter is to be used for impurity such as line bits in the filtration washing water, to guarantee having good clean result and higher clean ratio.A kind of line bits filter is arranged, and it comprises filter front shroud and filter bonnet, and bonnet is inserted in the axis hole of front shroud by the bearing pin of its underpart, and the filter front shroud is provided with permeable diaphragm.During washing, washings back down the non-return valve block from the filter bottom, enter filter chamber, behind the permeable membrane filtration on the front shroud, return washing cavities, washings are purified thus, and line bits are then stayed in the filter chamber and on the permeable diaphragm, and in the slit between front shroud and the bonnet.Thereby line bits filter need often take cleaning, and the bits of the line in the filter are washed.Thereby in the design of online bits filter, how front shroud and bonnet realize being convenient to dismounting, are beneficial to clean, and then are the factors that should consider emphatically.But the front shroud of above-mentioned line bits filter and the bottom of bonnet are connected, be that bearing pin by the bonnet bottom is inserted in the axis hole of front shroud, and the top connection is that the bonnet two sides respectively have a projection, makes bonnet and the mutual jam-packed of front shroud by this projection, connects with the top that forms both.When need are pulled down bonnet, start bonnet top, projection is in outside detach procedure, and front shroud breaks away from bonnet top and front shroud by distortion, and the bottom then still makes front shroud be connected with bonnet by bearing pin.There is following problem in this syndeton: 1, because front shroud and bonnet are still connection status, and can rotate around the axis, during cleaning, needs hand-held simultaneously front shroud and bonnet to clean, and very inconvenient, and be not easy to clean up.2, after use a period of time, the front shroud distortion, projection combines loosening with front shroud, the activity of front shroud and bonnet upper end is become flexible, and in conjunction with not firm, bonnet outwards drops out easily.If distortion is excessive, make the upper end can not in conjunction with, always have the trend of going out of outwards opening, then can cause whole line bits filter discarded.How overcoming the problems referred to above, then is the design problem that the research staff faced.

Summary of the invention

The utility model provides a kind of new molded lines bits filter, and it can solve prior art dismounting inconvenience that exists and the problem that is not easy to clean.

In order to reach the purpose that solves the problems of the technologies described above, the technical solution of the utility model is a kind of line bits filter, it comprises front shroud, bonnet, it is characterized in that: the syndeton of both sides, bonnet bottom is hemispherical projections, and above-mentioned projection is contained in the hole of front shroud bottom, and bonnet is connected with front shroud; Bonnet top is the stairstepping of inside indentation, and the front shroud corresponding position is provided with the retaining muscle.

In the utility model, also have following technical characterictic: the connecting hole of described front shroud bottom is a square hole.

In the utility model, also have following technical characterictic: the altitude range of described hemispherical projections is 0.4～0.6 of a hemisphere radius.

The utility model compared with prior art has the following advantages and good effect: 1, bonnet and front shroud top connected mode are that bonnet top is the stairstepping of inside indentation, the front shroud corresponding position is provided with the retaining muscle, during installation, earlier the bonnet upper end is sloped inwardly and be inserted at the end, keep flat then, the bonnet cascaded surface is blocked by front shroud retaining muscle, and the hemispherical projections of bottom by the bonnet bottom is enclosed in the corresponding square hole of front shroud, so just the location can be installed up and down.When need are pulled down bonnet, start the bottom, make hemispherical projections break away from square hole, take out downwards then, bonnet can be pulled down, folding is adorned very convenient.2, because after pulling down bonnet, front shroud separates with bonnet, can clean separately, hand-held convenient, and be easy to clean up.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in detail.

Fig. 1 is the front view of the utility model line bits filter;

Fig. 2 is the sectional view of the utility model line bits filter;

Fig. 3 is the cutaway view of the utility model front shroud, junction, bonnet bottom.

1, front shroud; 1-1, permeable diaphragm; 1-2, retaining muscle; 1-3, square hole; 2, bonnet; 2-1, hemispherical projections; 2-2, bonnet ladder place; 3, non-return valve block; 4, line bits filter.

The specific embodiment

Embodiment, referring to Fig. 1, Fig. 2 and Fig. 3, in order to improve the syndeton of line bits filter 4, be beneficial to cleaning and prevent that the connecting portion distortion from causing loosening, the syndeton of both sides, bonnet 2 bottom is hemispherical projections 2-1, projection 2-1 is contained in the square hole 1-3 of front shroud 1 bottom, makes be connected with the front shroud 1 bottom surface diameter of hemispherical projections 2-1 of bonnet 2 corresponding with the length of side of square hole 1-3.In this example, the height of hemispherical projections is 0.5 of a hemisphere radius.The type of attachment of hemispherical and square hole had both helped connecting, again easy disassembling.Bonnet 2 tops are the stairstepping 2-2 of inside indentation, and front shroud 1 corresponding position is provided with retaining muscle 1-2.

During installation, earlier bonnet 2 upper ends are sloped inwardly and inwardly be inserted at the end along filter chamber, make bonnet 2 place flat condition then, bonnet 2 cascaded surfaces are blocked by front shroud retaining muscle 1-2, can outwards not deviate from, and the hemispherical projections 2-1 of bottom by bonnet 2 bottoms is enclosed in the corresponding square hole 1-3 of front shroud, so just realized installing up and down the location.

When need are pulled down bonnet 2, start the bottom, in the process that starts, the sphere of hemispherical projections 2-1 is outwards deviate from from square hole 1-3 gradually, because sphere is in disengaging, the connecting portion of sphere projection 2-1 and square hole 1-3 reduces gradually, breaks away from square hole 1-3 until hemispherical projections 2-1, at this moment, bonnet 2 breaks away from the bottom of front shroud 1, takes out bonnet 2 then downwards, makes the 2-2 of ladder place of bonnet 2 break away from retaining muscle 1-3 place, bonnet 2 can be pulled down, folding is adorned very convenient.

The syndeton of above-mentioned front shroud 1 and bonnet 2 had both guaranteed to connect reliably, made front shroud 1 very easy and convenient with bonnet 2 dismountings again.

Certainly, the utility model is not limited to above-mentioned giving an example, and in essence intention scope of the present utility model, the utility model also has many variations, remodeling or replacement, all should belong to protection domain of the present utility model.
